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 

  
 22 

 
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. 
 Section 1.05

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-à-vis such party, shall be deemed controlling. The Agent shall not be liable, vis-à-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 unauthorized instructions or directions, and the risk of interception
and misuse by third parties.

as it appears in the 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.

execution of the Certificates. 

  
 28 

 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 of the
Purchase Contract Agent or its agent, in the Borough of Manhattan, The City of New York, New York, 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 of the Purchase Contract Agent or its agent in the Borough of Manhattan, The City of New York, New York, 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. 
 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 of the Purchase Contract Agent or its agent in
the Borough of Manhattan, The City of New York, New York. 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 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. 

  
 29 

 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, cause to be delivered the shares of Common Stock issuable in respect of the Purchase Contracts forming a
part of the Units evidenced by such other Certificate (or portion thereof) on the applicable Settlement Date; and 
 (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 Debentures, 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 V. 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 or between or among Depositary Participants) 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. 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,

  
 30 

 
except as provided in Section 3.09. The Purchase Contract Agent shall enter into an agreement with the Depository as required by the Depository in connection herewith and 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 and the Agents 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 evidenced by Global Certificates 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. Neither the Purchase Contract Agent nor any other Agent shall have any responsibility for any actions taken or not taken by the Depository. 

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 Depositary constitutes a “clearing agency” registered under
Section 17A of the Exchange Act. 

  
 31 

 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 Debentures, or any event that after notice or lapse of time would constitute an Event of Default with respect to the Debentures, 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 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. 

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 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. 

  
 32 

 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 Debentures, 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 V. 
 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. 
 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. 

  
 33 

 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 Debentures underlying the Applicable Ownership Interests in Debentures, on the Applicable Ownership Interests in the
Treasury Portfolio (as specified in clause (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
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 

  
 34 

 
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 Debentures underlying the Applicable Ownership Interests in Debentures, 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, effect a Collateral Substitution and separate
the Debentures underlying the Pledged Applicable Ownership Interests in Debentures in respect of such Holder’s Corporate Units by substituting for such Pledged Applicable Ownership Interests in Debentures for which Collateral Substitution is
being made, Treasury Securities in an aggregate principal amount at maturity equal to the aggregate principal amount of the Debentures underlying the Pledged Applicable Ownership Interests in Debentures; 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures for which such Collateral Substitution is made; and 

  
 35 

 (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 Debentures
from the Pledge by directing the Securities Intermediary by a notice, substantially in the form of Exhibit G hereto, to Transfer the Debentures underlying such Pledged Applicable Ownership Interests in Debentures 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 Debentures underlying the appropriate Pledged Applicable Ownership Interests in Debentures to the Purchase Contract Agent
for distribution to such Holder, free and clear of the Pledge created hereby. 
 Upon receipt of the Debentures underlying such Pledged
Applicable Ownership Interests in Debentures, the Purchase Contract Agent shall promptly: 
 (i) cancel the related Corporate
Units; 
 (ii) Transfer the Debentures 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. 

Holders who elect to separate the Debentures by substituting Treasury Securities for Applicable Ownership Interest in Debentures 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. 

  
 36 

 (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 Debentures underlying the Applicable Ownership Interests in Debentures 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 Debentures 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 Re-creation 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; 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 Debentures 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 Debentures 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. 
 The substituted Debentures 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. 

  
 37 

 Upon credit to the Collateral Account of Debentures 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 Debentures underlying Pledged Applicable Ownership Interests in
Debentures or security entitlements with respect thereto or Applicable Ownership Interests in the Treasury Portfolio; 
 (ii)
any Pledged Treasury Securities; 
 (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, 

  
 38 

 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 Debentures 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, Debentures
in denominations of $50, or integral multiples thereof, in exchange for Debentures 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 Debentures underlying Pledged Applicable Ownership Interests in Debentures, 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(b)(ix) 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 Debentures underlying Pledged Applicable Ownership Interests in Debentures, 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(b)(ix) 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 Debentures underlying Pledged Applicable Ownership Interests in Debentures, 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(b)(ix) 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. 

  
 39 

 (c) Upon the occurrence of a Termination Event and the Transfer to the Purchase Contract
Agent of the Debentures underlying Pledged Applicable Ownership Interests in Debentures, 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 Debentures, Applicable Ownership Interests in the Treasury Portfolio and/or Pledged Treasury Securities, as the case may be, from each Holder by
written request, substantially in the form of Exhibit D hereto, mailed to such Holder at its address as it appears in the Security Register. 

(d) Upon book-entry transfer of the Corporate Units or the Treasury Units or delivery of a Corporate Units Certificate or Treasury Units
Certificate to the Purchase Contract Agent with such transfer instructions in connection with a Termination Event, the Purchase Contract Agent shall transfer the Debentures underlying Pledged Applicable Ownership Interests in Debentures, the
Applicable Ownership Interests in the Treasury Portfolio or Pledged Treasury Securities, as the case may be, underlying such Corporate 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 Debentures underlying Pledged Applicable Ownership Interests in Debentures, in accordance with the terms of the Indenture. In the event a Holder of Corporate Units or Treasury
Units fails to deliver transfer instructions or effect such transfer or delivery, the Debentures underlying Pledged Applicable Ownership Interests in Debentures, 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 Purchase Contract Agent holds such property.

to have expressly withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its trustee, receiver, liquidator or a person or entity performing similar functions in
the event that the Company becomes a debtor under the Bankruptcy Code or subject to other similar state or federal law providing for reorganization or liquidation. 

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

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 Debentures or Applicable Ownership Interests in the Treasury Portfolio underlying such other Corporate Units Certificate.

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

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 or are
not clear, such funds shall remain uninvested and the Purchase Contract Agent shall have no liability for payment of interest on such uninvested funds. In no event shall the Collateral Agent or the Securities Intermediary be liable for the selection

investment direction.

transferred to the Purchase Contract Agent for the benefit of the applicable Holders for distribution to such Holders in accordance with their respective interests. 

Section 4.03 Notice and Voting. (a) Subject to Section 4.03(b) hereof, the Purchase Contract
Agent shall have no responsibility to exercise, or refrain from exercising, any and all voting and other consensual rights pertaining to the Debentures underlying Pledged Applicable Ownership Interests in Debentures or any part thereof. Upon receipt
of any notices and other communications in respect of any Debentures underlying Pledged Applicable Ownership Interests in Debentures, including either notice of any meeting at which holders of the Debentures are entitled to vote or the solicitation
of consents, waivers or proxies of holders of the Debentures, 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 Debentures underlying Pledged Applicable Ownership Interests in
Debentures as are timely prepared by the Company and delivered to the Purchase Contract Agent with respect to the Debentures underlying Pledged Applicable Ownership Interests in Debentures. 

(b) Upon receipt of notice of any meeting at which holders of Debentures are entitled to vote or upon any solicitation of consents, waivers or
proxies of holders of Debentures, 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 Debentures entitled to vote) shall be entitled to instruct the Purchase Contract Agent as to the exercise of the voting rights pertaining to such Debentures
underlying the Applicable Ownership Interests in Debentures 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 Debentures (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 Debentures underlying Applicable Ownership Interests in Debentures 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 Debentures. 

  
 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.

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 Debentures or distributions on the Applicable Ownership Interests in the
Treasury Portfolio (as specified in clause (ii) of the definition thereof)) and not released therefrom in accordance with this Agreement, the Purchase Contract Agent or such Holder shall, upon receipt of an Officer’s Certificate of the
Company so directing, promptly deliver such payments to the Securities Intermediary for credit to the Collateral Account or, if the Obligations have become due and payable, to the Company for application to the Obligations of the applicable Holder
or Holders. 
 ARTICLE V 
 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 by the Company as follows: 

(i) If the Applicable Market Value is equal to or greater than the Threshold Appreciation Price, the Settlement Rate will be 0.5003 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 $83.29 (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 0.6003 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 Market Value Averaging Period, all remaining Trading Days shall be deemed to
occur on the third Scheduled Trading Day immediately prior to the Purchase Contract Settlement Date and the VWAP for each of the remaining Trading Days will be the VWAP on such third 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 AEP <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 Scheduled Trading Days ending on the third Scheduled Trading Day
immediately preceding the Purchase Contract Settlement Date. 
 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. 

  
 45 

 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: 

(i) 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 a 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 
 (ii) any event (other than a failure to
open or, except for purpose of determining a 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 a 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 
 (iii) 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 a 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. 

(b) Each Holder of a Corporate Unit or a Treasury Unit, by purchasing 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; 

  
 46 

 (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 Debentures, 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 Debentures, 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. 
 Section 5.02
Remarketing. 
 (a) Optional Remarketing. (i) Unless a Termination Event has occurred, the Company may
elect, at its option, to engage the Remarketing Agent(s), pursuant to the terms of the Remarketing Agreement, to remarket the aggregate Debentures underlying the aggregate Applicable Ownership Interests in Debentures that are components of Corporate
Units, along with any Separate Debentures, the holders of which have elected to participate in such remarketing pursuant to the Indenture and Section 5.02(d), over a period of one or more days selected by the Company that begins on or after the
second Business Day immediately preceding the Interest Payment Date immediately prior to the Purchase Contract Settlement Date and ends any time on or before the eighth calendar day prior to the beginning of the Final Remarketing Period (such
period, the “Optional Remarketing Period”); provided that, notwithstanding anything to the contrary herein, the Company may only elect to conduct an Optional Remarketing if it is not then deferring interest on the Debentures.

  
 47 

 (i) The Company shall request that the Depository notify the Depository
Participants holding Corporate Units, Treasury Units and Separate Debentures of the Company’s election to conduct an Optional Remarketing no later than five Business Days prior to the first day of the Optional Remarketing Period, and the
Company shall provide a copy of such request to the Purchase Contract Agent, Collateral Agent and Custodial Agent. 
 (ii) If
the Company elects to conduct an Optional Remarketing on an Optional Remarketing Date, 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures 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 Debentures (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 Debentures at the applicable Remarketing Price. 

(iii) Reserved. 

(iv) Reserved. 

(v) If the Remarketing Agent(s) is able to remarket the Debentures 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures upon confirmation of deposit to the Collateral Account of proceeds of such Successful Optional Remarketing attributable to such Debentures underlying the
Pledged Applicable Ownership Interests in Debentures, and the Custodial Agent shall Transfer the remarketed Separate Debentures 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 Debentures Account”) of receipt of proceeds of such Successful Optional Remarketing attributable to such Separate Debentures. Settlement shall occur on the Optional
Remarketing Settlement Date. Upon deposit in the Collateral Account of such proceeds attributable to the remarketed Debentures underlying the Pledged Applicable Ownership Interest in Debentures, the Collateral Agent shall
(A) unless the Treasury Portfolio shall consist of Cash, (x) instruct the Securities Intermediary to apply an amount equal to the Treasury Portfolio Purchase Price to purchase the Treasury Portfolio from the dealer identified by the
Quotation Agent pursuant to the definition of “Treasury Portfolio Purchase Price” (the amount and issue of the U.S. Treasury securities (or principal or interest strips thereof) constituting the Treasury Portfolio to be determined by the
Remarketing Agent(s), who shall provide 

  
 48 

 
such information to the Collateral Agent and the Quotation Agent, who will then determine, and notify the Collateral Agent of, the Treasury Portfolio Purchase Price) and (y) credit to the
Collateral Account the Applicable Ownership Interests in the Treasury Portfolio, (B) if the Treasury Portfolio shall consist of Cash, credit to the Collateral Account Cash in an amount equal to the 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 Optional Remarketing Settlement Date to
such Holders pro rata in accordance with their interests. With respect to any Separate Debentures remarketed, upon receipt of proceeds of such Successful Optional Remarketing attributable to the remarketed Separate Debentures, the Custodial
Agent shall remit the proceeds of such Separate Debentures sold in the Successful Optional Remarketing received from the Remarketing Agent(s) pro rata to the holders of such Separate Debentures on the Optional Remarketing Settlement Date in
accordance with the instructions provided in the form of Exhibit K.

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. 

(vii) Following the occurrence of a Successful Optional Remarketing, the Applicable Ownership Interests in the Treasury
Portfolio (as specified in clause (i) of such term) will be substituted as Collateral for the Pledged Applicable Ownership Interests in Debentures 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 (i) of such term) as the Holder of Corporate Units and the Collateral Agent had in respect of the Pledged Applicable Ownership Interests in Debentures and the underlying Debentures, 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 Debentures shall thereupon be deemed to be a reference to such Applicable Ownership Interests in the Treasury Portfolio
(as defined in clause (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 (i) of such term) for the Pledged Applicable Ownership Interests in Debentures as Collateral. 

(viii) Following a Successful Optional Remarketing, the Remarketing Agent(s) shall remit (1) the proceeds attributable to
the remarketed Debentures underlying the Pledged Applicable Ownership Interest in Debentures to the Collateral Agent and (2) the proceeds attributable to the remarketed Separate Debentures to the Custodial Agent for the benefit of the Holders
of Separate Debentures that had their Debentures remarketed. 

  
 49 

 (ix) If, in spite of its commercially reasonable efforts, the Remarketing
Agent(s) cannot remarket the Debentures 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 Debentures
that were to be subject to such Optional Remarketing to the appropriate holders pursuant to the instructions provided in the form of Exhibit K. 

(x) If the Company elects to remarket the Debentures during the Optional Remarketing Period and a Successful Optional
Remarketing has not occurred on or prior to the last day of the Optional Remarketing Period, the Company shall cause 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. 
 (xi) The Company will pay the
Remarketing Fee in connection with any Successful Optional Remarketing. Holders whose Debentures are part of a Successful Optional Remarketing will not be responsible for payment of the Remarketing Fee. 

(xii) 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 or a Successful Optional Remarketing has previously occurred, in order to
dispose of the Debentures underlying Pledged Applicable Ownership Interests in Debentures 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 Debentures, along with any Separate Debentures, 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 Debentures of the Final Remarketing no later than seven 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
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 Debentures to participate in the Final Remarketing,

  
 50 

 
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 Debenture in the case of a Failed
Remarketing if such holder of Separate Debentures 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

principal amount of Separate Debentures (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 Debentures and such Separate Debentures at the applicable Remarketing
Price. 
 (iv) Reserved. 

(v) If the Remarketing Agent(s) is able to remarket such Debentures and the Separate Debentures (if any) for at least the
applicable Remarketing Price 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures upon confirmation of deposit to the Collateral Account of proceeds of such Successful Final Remarketing attributable to such Debentures, and the
Custodial Agent shall Transfer the remarketed Separate Debentures to the Remarketing Agent(s) upon confirmation of deposit to the Separate Debentures Account of proceeds of such Successful Final Remarketing attributable to such Separate Debentures.
Settlement shall occur on the Remarketing Settlement Date. Upon deposit in the Collateral Account of such proceeds attributable to the remarketed Debentures underlying the Pledged Applicable Ownership in Debentures, 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 Debentures underlying Pledged Applicable Ownership Interests
in Debentures 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 the Holders of Corporate Units who have elected Cash Settlement, and

  
 51 

 
paid the Purchase Price as required by Section 5.03(a)(ii), the Debentures underlying the Applicable Ownership Interest in Debentures underlying such Corporate Units. With respect to any
Separate Debentures remarketed, upon receipt of proceeds attributable to remarketed Separate Debentures, 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 Debentures 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 Debentures underlying the Pledged Applicable Ownership Interest in Debentures to the Collateral Agent and (2) the proceeds attributable to the remarketed Separate Debentures to the Custodial Agent for the benefit of the Holders of
Separate Debentures that had their Debentures 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, including
all Deferred Interest (and compounded interest thereon), to be paid to the Holders of the Debentures, as of the relevant Record Date (as defined in the Indenture) (whether or not such Debentures 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 Debentures 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 Debentures, 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 second 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 second 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 of 20 Corporate Units), shall be deemed to have exercised such

  
 52 

 
Holder’s Put Right with respect to the Debentures underlying such Pledged Applicable Ownership Interests in Debentures 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 Debentures underlying such Pledged Applicable Ownership Interests in Debentures
from the Collateral Account and shall promptly transfer such Debentures 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 written instructions of the Company with respect to Cash Settlement, (Y) promptly release from the
Pledge the Debentures underlying the Applicable Ownership Interest in Debentures related to the Corporate Units as to which such Holder has paid such separate cash and (Z) promptly Transfer all such Debentures 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 Debentures 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 Debentures, 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 Debentures 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 Debentures from exercising their Put Right after a Failed Final
Remarketing. 

  
 53 

 (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. 

(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 Debentures
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 Debentures underlying the Pledged Applicable Ownership in Debentures will be substituted as Collateral for the Pledged Applicable Ownership Interests in
Debentures 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 Debentures. 
 (c) In connection with
any Remarketing, the Company may elect, in consultation with the Remarketing Agent(s) to, among other things, remarket the Debentures as fixed-rate notes or floating-rate notes and, in the case of floating-rate notes, provide that the interest rate
on the Debentures shall be equal to an index selected by the Company plus a spread determined by the Remarketing Agent, in consultation with the Company, in which case interest on the Debentures may be calculated on the basis of a 365 day year and
the actual number of days elapsed (or such other basis as is customarily used for floating-rate notes bearing interest at a rate based on such index rate). These modifications shall become effective if the Remarketing is successful, without the
consent of the Holders, upon the earlier of the Optional Remarketing Settlement Date and the Purchase Contract Settlement Date and shall apply to all the Debentures, whether or not included in such Remarketing; provided, however, that if the
Company makes any such elections in connection with an Optional Remarketing and no Successful Remarketing occurs during the Optional Remarketing Period, such elections shall cease to apply and the Company may make new elections in connection with
the Final Remarketing. If a Successful Remarketing occurs, the Company will request the Depository to notify the Depository Participants holding Debentures of the Reset Rate, whether the interest rate is fixed or floating, interest payment dates and
maturity for the Debentures on the Business Day following the date of the Successful Remarketing. 
 (d) At any time following notice by the
Company of a Remarketing, other than during a Blackout Period, holders of Separate Debentures may elect to have their Separate Debentures remarketed in such Remarketing in the same manner as the Debentures included in Corporate

  
 54 

 
Units by delivering their Separate Debentures 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 Debentures in an account separate from the Collateral Account in which any Pledged Applicable Ownership Interests in Debentures and/or any Pledged Treasury Securities shall be held. Holders electing to have their Separate Debentures
remarketed shall also have the right to withdraw the election 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 Debentures that elects to have its Debentures remarketed shall receive for each
$1,000 principal amount of Debentures, the Remarketing Price Per Debenture. In the event of a Successful Remarketing during the Final Remarketing Period, each holder of Separate Debentures that elects to have its Debentures remarketed shall receive
its pro rata portion of the proceeds of such Successful Remarketing attributable to remarketed Separate Debentures pursuant to 5.02(b)(v), which shall be, for each $1,000 principal amount of Debentures, at least equal to $1,000 in cash. Any
accrued and unpaid interest on such Debentures, including any accrued and unpaid Deferred Interest (including compounded interest thereon), 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 Debentures underlying the aggregate Applicable Ownership Interests in
Debentures 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
Debentures, the holders of which have elected to participate in any Remarketing, to have such Debentures remarketed 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 Debentures at the
applicable Remarketing Price based on the Reset Rate and (iv) each condition precedent to settlement of the remarketed Debentures 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 Debentures 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 Remarketing has occurred, each Holder of Corporate Units
shall have the right, subject to the conditions set 

  
 55 

 
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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures pursuant to any Remarketing occurring
in the Final Remarketing Period as set forth in Section 5.02(b) or to have exercised such Holder’s Put Right, in each case, as applicable. 

(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 Debentures 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); 

  
 56 

 (B) release from the Pledge the Debentures underlying the Applicable
Ownership Interest in Debentures 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 Debentures 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 Debentures 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 Debentures, 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 Debentures and interest payments thereon, if any, are held. 

The Company shall instruct the Collateral Agent in writing as to the specific investment, which shall be a 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 9:00 a.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 specific investment, which shall be 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 or is not clear, such Cash shall remain uninvested and the Purchase Contract Agent shall have no
liability for interest on such uninvested funds. 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. 

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. 

  
 57 

 (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 Debentures 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 or is not clear, 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 (whether under Section 5.01, 5.02,
5.03, 5.05(b)(ii) or 5.08 or otherwise). 
 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. 

  
 58 

 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 V (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 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. 
 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 pays or makes a dividend or other
distribution on the Common Stock in shares of Common Stock, each Fixed Settlement Rate in effect at the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such dividend or other
distribution shall be increased by dividing each Fixed Settlement Rate by a fraction, 
 (A) the numerator of which
shall be the number of shares of the Common Stock outstanding at the close of business on the date fixed for such determination; and 

(B) the denominator of which shall be the sum of such number of shares and the total number of shares constituting such
dividend or other distribution. 

  
 59 

 Any adjustment made under this clause (i) shall become effective immediately after the
opening of business on the day following the date fixed for the determination of shareholders entitled to receive such dividend or other distribution. If any dividend or distribution of the type described in this clause (i) is declared but not
so paid or made, each Fixed Settlement Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Fixed Settlement Rate that would then be in effect if
such dividend or distribution had not been declared. 
 (ii) If the Company issues to all or substantially all holders of the
Common Stock rights, options, warrants or other securities (other than pursuant to a dividend reinvestment, share purchase or similar plan), entitling them to subscribe for or purchase shares of the Common Stock for a period expiring within 45 days
from the date of issuance of such rights, options, warrants or other securities at a price per share of Common Stock less than the Current Market Price calculated as of the date fixed for the determination of shareholders entitled to receive such
rights, options, warrants or other securities, each Fixed Settlement Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing each Fixed Settlement Rate by a fraction,

 (A) the numerator of which shall be the number of shares of the Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock which the aggregate consideration expected to be received by the Company upon the exercise of such rights, options, warrants or other securities would purchase at
such Current Market Price; and 
 (B) the denominator of which shall be the number of shares of the Common Stock outstanding
at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase. 

Any increase in the Fixed Settlement Rates made pursuant to this clause (ii) shall become effective immediately after the opening of
business on the day following the date fixed for the determination of shareholders entitled to receive such rights, options, warrants or other securities. To the extent such rights, options, warrants or other securities are not exercised or
converted prior to their 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, warrants or other securities), each new Fixed
Settlement Rate shall be readjusted, effective 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, warrants or other securities 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, warrants or other securities entitle the holders thereof to subscribe for or purchase shares of the Common Stock at less than the Current Market Price per share of Common Stock on the date fixed for the
determination of shareholders entitled to receive such rights, options, warrants or other 

  
 60 

 
securities, and in determining the aggregate price payable to exercise such rights, options, warrants or other securities, there shall be taken into account any consideration the Company receives
for such rights, options, warrants or other securities 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. 

(iii) If outstanding shares of the Common Stock shall be subdivided, split or reclassified into a greater number of shares of
Common Stock, each Fixed Settlement Rate in effect at the opening of business on the day following the day upon which such subdivision, split or reclassification becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of the Common Stock shall each be combined or reclassified into a smaller number of shares of Common Stock, each Fixed Settlement Rate in effect at the opening of business on the day following the day upon which such combination
or reclassification becomes effective shall be proportionately reduced. 
 (iv) If the Company, by dividend or otherwise,
distributes to all or substantially all holders of the Common Stock evidences of the Company’s indebtedness, assets or securities or any rights, options or warrants (or similar securities) to subscribe for, purchase or otherwise acquire
evidences of the Company’s indebtedness, other assets or property of the Company or other securities (but excluding any rights, options, warrants or other securities referred to in clause (ii) of this Section 5.05(a), any dividend or
distribution paid exclusively in cash referred to in clause (v) below of this Section 5.05(a) (in each case, whether or not an adjustment to the Fixed Settlement Rates is required by such clause), any dividend paid in shares of capital
stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit of the Company in the case of a Spin-Off referred to below, or dividends or distributions
referred to in clause (i) of this Section 5.05(a)), each Fixed Settlement Rate in effect immediately prior to the close of business on the date fixed for the determination of shareholders entitled to receive such dividend or distribution
shall be increased by dividing each Fixed Settlement Rate by a fraction, 
 (A) the numerator of which shall be the
Current Market Price calculated as of the date fixed for such determination less the then fair market value (as determined in good faith by the Board of Directors) of the portion of the assets, securities or evidences of indebtedness so
distributed applicable to one share of the Common Stock; and 
 (B) the denominator of which shall be such Current Market
Price. 
 Any increase made under the portion of this clause (iv) shall become effective immediately after the close of business on the date fixed for
the determination of shareholders entitled to receive such dividend or distribution. Notwithstanding the foregoing, if the fair market value (as determined in good faith by the Board of Directors) of the portion of the assets, securities or
evidences of indebtedness so distributed applicable to one share of the Common Stock exceeds the Current Market Price of the Common Stock on the date fixed for the determination of shareholders entitled to receive such distribution, in lieu of the
foregoing increase, each Holder 

  
 61 

 
shall receive, for each Purchase Contract included in such Holder’s Units, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of such distributed
assets, securities or evidences of indebtedness that such Holder would have received if such Holder owned a number of shares of the Common Stock equal to the Maximum Settlement Rate on the record date for such dividend or distribution. 

In the case of the payment of a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity
interests, of or relating to a subsidiary or other business unit of the Company, which are or will, upon issuance, be listed on a U.S. securities exchange or quotation system (a “Spin-Off”),
each Fixed Settlement Rate in effect immediately before the close of business on the date fixed for determination of shareholders entitled to receive such dividend or distribution will be increased by dividing each Fixed Settlement Rate by a
fraction, 
 (A) the numerator of which is the Current Market Price; and 

(B) the denominator of which is such Current Market Price plus the Fair Market Value (determined as set forth below) of
those shares of capital stock or similar equity interests so distributed applicable to one share of Common Stock. 
 The adjustment to each
Fixed Settlement Rate under the immediately preceding paragraph will occur on (A) the 10th Trading Day from and including the effective date of the Spin-Off; or (B) if the Spin-Off is effected simultaneously with an Initial Public Offering of the securities being distributed in the Spin-Off and the Ex-Date
for the Spin-Off occurs on or before the date that the Initial Public Offering price of the securities being distributed in the Spin-Off is determined, the issue date of
the securities being offered in such Initial Public Offering. For purposes of this section, “Initial Public Offering” means the first time securities of the same class or type as the securities being distributed in the Spin-Off are offered to the public for cash. 
 Subject to the immediately following paragraph, the
“Fair Market Value” of the securities to be distributed to holders of Common Stock means the average of the closing sale prices of those securities on the principal U.S. securities exchange or quotation system on which such
securities are listed or quoted at that time over the first 10 Trading Days following the effective date of the Spin-Off. For purposes of such a Spin-Off, the
“Current Market Price” of the Common Stock means the average of the closing sale prices of the Common Stock on the principal U.S. securities exchange or quotation system on which the Common Stock is listed or quoted at that time
over the first 10 Trading Days following the effective date of the Spin-Off. 
 If, however, an
Initial Public Offering of the securities being distributed in the Spin-Off is to be effected simultaneously with the Spin-Off and the
Ex-Date for the Spin-Off occurs on or before the date that the Initial Public Offering price of the securities being distributed in the
Spin-Off is determined, the “Fair Market Value” of the securities being distributed in the Spin-Off means the Initial Public Offering price, while the
“Current Market Price” of the Common Stock means the closing sale price of the Common Stock on the principal U.S. securities exchange or quotation system on which the Common Stock is listed or quoted at that time on the Trading Day
on which the Initial Public Offering price of the securities being distributed in the Spin-Off is determined.

 If any dividend or distribution described in this clause (iv) is declared but not so
paid or made, the new Fixed 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 Fixed Settlement Rates that would then be in effect if such dividend or
distribution had not been declared. 
 For purposes of this clause (iv) (and subject in all respect to clause (x) below), rights,
options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock, including Common Stock (either initially or under certain circumstances), which
rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (a) are deemed to be transferred with such shares of the Common Stock; (b) are not exercisable; and (c) are also issued in
respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this clause (iv) (and no adjustment to the Fixed Settlement Rates under this clause (iv) will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Fixed Settlement Rates shall be made under this clause (iv). If any such right,
option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Agreement, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such rights (in
which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or
warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Fixed Settlement Rates
under this clause (iv) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Fixed
Settlement Rates shall be readjusted as if such rights, options or warrants had not been issued and (y) the Fixed Settlement Rates shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the
case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights,
options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof,
the Fixed Settlement Rates shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of clause (i),
clause (ii) and this clause (iv), if any dividend or distribution to which this clause (iv) is applicable also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which clause (i) is applicable (the “Clause
(i) Distribution”); or 

  
 63 

 (B) a dividend or distribution of rights, options or warrants to which
clause (ii) is applicable (the “Clause (ii) Distribution”), 
 then, in either case, (1) such dividend or distribution, other than
the Clause (i) Distribution and the Clause (ii) Distribution, shall be deemed to be a dividend or distribution to which this clause (iv) is applicable (the “Clause (iv) Distribution”) and any Fixed Settlement Rate
adjustment required by this clause (iv) with respect to such Clause (iv) Distribution shall then be made, and (2) the Clause (i) Distribution and Clause (ii) Distribution shall be deemed to immediately follow the Clause
(iv) Distribution and any Fixed Settlement Rate adjustment required by clause (i) and clause (ii) with respect thereto shall then be made, except that, if determined by the Company (I) the record date of the Clause
(i) Distribution and the Clause (ii) Distribution shall be deemed to be the record date of the Clause (iv) Distribution and (II) any shares of Common Stock included in the Clause (i) Distribution or Clause
(ii) Distribution shall be deemed not to be “outstanding at the close of business on the date fixed for such determination” within the meaning of clause (i) or clause (ii). 

(v) If the Company, by dividend or otherwise, makes distributions to all or substantially all holders of the Common Stock
exclusively in cash during any quarterly period in an amount that exceeds $0.70 per share per quarter in the case of a regular quarterly dividend (such per share amount being referred to as the “Reference Dividend,” which shall be
adjusted proportionally for any change in frequency of the Company’s regular dividends), then immediately after the close of business on the date fixed for determination of the shareholders entitled to receive such distribution, each Fixed
Settlement Rate in effect immediately prior to the close of business on such date shall be increased by dividing each Fixed Settlement Rate by a fraction, 

(A) the numerator of which shall be equal to the Current Market Price on the date fixed for such determination less the
amount, if any, by which the per share amount of the distribution exceeds the Reference Dividend; and 
 (B) the denominator
of which shall be equal to such Current Market Price. 
 Such increase shall become effective immediately after the close of business on the
date fixed for determination of the shareholders entitled to receive such distribution. Notwithstanding the foregoing, if (x) the amount by which the per share amount of the cash distribution exceeds the Reference Dividend exceeds (y) the
Current Market Price of the Common Stock on the date fixed for the determination of shareholders entitled to receive such distribution, in lieu of the foregoing increase, each Holder shall receive, for each Purchase Contract included in such
Holder’s Units, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of distributed cash that such Holder would have received if such Holder owned a number of shares of the Common Stock equal to the
Maximum Settlement Rate on the record date for such cash dividend or distribution. If such distribution is declared but not so paid or made, each Fixed Settlement Rate shall be decreased, effective as of the date the Board of Directors determines
not to pay or make such dividend, to the Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 64 

 The Reference Dividend will be subject to an inversely proportional adjustment (determined
in the same manner as the adjustment to the Reference Price and Threshold Appreciation Price set forth below in clause (vii) of this Section 5.05(a)) whenever each Fixed Settlement Rate is adjusted, other than pursuant to this clause (v).
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. 

(vi) In the case that a tender offer or exchange offer made by the Company or any subsidiary thereof for all or any portion of
shares of the Common Stock shall expire and such tender or exchange offer (as amended through the expiration thereof) shall require the payment to shareholders (based on the acceptance (up to any maximum specified in the terms of the tender offer or
exchange offer) of Purchased Shares) of an aggregate consideration having a fair market value per share of the Common Stock that 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 offer or exchange offer, then, immediately prior to the opening of business on the day after the date of the last time (the “Expiration Time”) tenders or exchanges could have been made
pursuant to such tender offer or exchange offer (as amended through the expiration thereof), each Fixed Settlement Rate in effect immediately prior to the close of business on the date of the Expiration Time shall be increased by dividing
each Fixed Settlement Rate, by a fraction, 
 (A) the numerator of which shall be equal to (x) the product of
(i) the Current Market Price on the date of the Expiration Time and (ii) the number of shares of Common Stock outstanding (including any Purchased Shares) on the date of the Expiration Time less (y) the amount of cash
plus the fair market value of the aggregate consideration payable to shareholders pursuant to the tender offer or exchange offer (assuming the acceptance of Purchased Shares); and 

(B) the denominator of which shall be equal to the product of (x) the Current Market Price on the date of the Expiration
Time and (y) the result of (i) the number of shares of the Common Stock outstanding (including any Purchased Shares) on the date of the Expiration Time less (ii) the number of all shares validly tendered, not withdrawn and
accepted for payment on the date of the Expiration Time (such actually validly tendered or exchanged shares, up to any maximum acceptance amount specified by the Company in the terms of the tender offer or exchange offer, the “Purchased
Shares”). 
 In the event the Company is, or one of the Company’s subsidiaries is, obligated to purchase shares of Common
Stock pursuant to any such tender or exchange offer, but the Company is, or such subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then each Fixed Settlement Rate shall be
readjusted to the Fixed Settlement Rate that would then be in effect if such tender or exchange offer had not been made. 

  
 65 

 (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)(vi) 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)(vi) of this Section 5.05.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. 
 (viii) All
adjustments to the Fixed Settlement Rate shall be calculated 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 

  
 66 

 
under this Section 5.05(a) shall be made no later than each day of any Market Value Averaging Period and the time at which the Company is otherwise 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. The Company may only make such a discretionary adjustment if the Company makes the same proportionate adjustment to each Fixed Settlement Rate. 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. If the Company or another applicable withholding agent pays withholding taxes on behalf of a Holder or beneficial owner of a Purchase Contract as a result of an adjustment to the Fixed Settlement Rate, the Company or such
other applicable withholding agent may set off such payments against payments on such Purchase Contract, including any Common Stock received upon purchase on the Settlement Date. 

(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)(iv), 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 

  
 67 

 
provides for different treatment of Common Stock held by a Constituent Person and/or the Affiliates of a 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 (x) the weighted average of the types and amounts of consideration
received by the holders of Common Stock that affirmatively make an election or (y) if no holders of the Common Stock affirmatively make such an election, 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 Officer’s Certificate 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 

  
 68 

 
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). 
 (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 30th Scheduled Trading 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 were determined, for such purpose, based on the Market Value Averaging Period starting on the 23rd Scheduled Trading Day prior to the Fundamental
Change Early Settlement Date and ending on the third Scheduled Trading Day immediately preceding the Fundamental Change Early Settlement Date, 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 if 20 Trading Days for the Common Stock have not occurred during such
deemed Market Value Averaging Period, all remaining Trading Days will be deemed to occur on the third Scheduled Trading Day immediately prior to the Fundamental Change Early Settlement Date and the VWAP for each of the remaining Trading Days will be
the VWAP on such third Scheduled Trading Day or, if such day is not a Trading Day, the Closing Price of the Common Stock as of such day; provided further that no Fundamental Change Early 

  
 69 

 
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 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 third Scheduled Trading Day preceding the Purchase Contract Settlement Date) and the Fundamental Change Early Settlement Date shall be postponed to the third Scheduled Trading Day following the end of the Fundamental
Change Exercise Period. The Company shall provide written notice to Holders of Units of any such extension and postponement at least 23 Scheduled Trading Days prior to such extension and postponement. 

The Company shall provide written notice to Holders of Units of the completion of a Fundamental Change within four Scheduled Trading Days
after the Effective Date (as hereinafter defined) of a Fundamental Change, which shall specify (1) an early settlement date (subject to postponement, as set forth above, the “Fundamental Change Early Settlement Date”), which
shall be at least 26 Scheduled Trading Days after the date of the notice and 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, (2) the date by which Holders must exercise the Fundamental Change Early Settlement Right, which shall be no earlier than the second Scheduled Trading Day before the Fundamental Change Early Settlement Date,
(3) the first Scheduled Trading Day of the deemed Market Value Averaging Period, which will be the 23rd Scheduled Trading Day prior to the Fundamental Change Early Settlement Date, the
Reference Price, the Threshold Appreciation Price, and the Fixed Settlement Rates, (4) the amount and kind (per share of Common Stock) of cash, securities 

  
 70 

 
and other consideration receivable by the Holder upon settlement and (5) 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 Debentures
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 multiples of 160,000 Corporate Units. 

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 of the Purchase Contract Agent or its agent in the Borough of Manhattan, The City of New York, New York, 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 third Scheduled Trading 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 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures 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 

  
 71 

 
specified in clause (ii) of the definition thereof) or Debentures underlying Pledged Applicable Ownership Interests in Debentures 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); 

(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 Debentures, 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. 

  
 72 

 (iii) The number of Make-Whole Shares per Purchase Contract deliverable upon
a Fundamental Change Early Settlement 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 (ii) 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. 
 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. 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 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.

 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 year, as applicable; 

  
 73 

 (2) if the Stock Price is in excess of $300.00 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 $30.00 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) The Fixed Settlement Rates shall not be
adjusted (subject to Section 5.05(a)(ix)): 
 (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; 
 (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) Each adjustment to each Fixed Settlement Rate will result in a corresponding adjustment to the number of shares of Common Stock issuable
upon Early Settlement. 
 (e) 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 Officer’s 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 

  
 74 

 (ii) provide a written notice to the Holders of the Units 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 Officer’s 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 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 V. 

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 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 Debentures (or security entitlements with respect thereto) underlying the Applicable Ownership Interests in Debentures, 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
Debentures (or security entitlements with respect thereto) underlying the Pledged Applicable Ownership Interests in Debentures or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (i) of the definition of
Applicable Ownership Interests in the Treasury Portfolio) 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. 

  
 75 

 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 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. 
 (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 of the Purchase Contract Agent or its
agent in the Borough of Manhattan, The City of New York, New York, 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. 

  
 76 

 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures, or the Pledged Applicable Ownership
Interests in the Treasury Portfolio, as the case may be, relating to the Purchase Contracts to which Early Settlement is effected, or (2) in the case of a Holder of Treasury Units, 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 (ii) of the definition thereof) or Debentures underlying such Pledged Applicable Ownership Interests in Debentures 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 Debentures as a component of the Corporate Units, Corporate Units Holders may only effect Early Settlement pursuant to this Section 5.08 in integral multiples of 160,000
Corporate Units. 

  
 77 

 (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 Debentures, the Applicable Ownership Interests 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. 
 (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 Debentures, 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
Debentures, the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, related to such Units, 

(ii) cause to be delivered 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); provided that, for the avoidance of doubt, the Purchase Contract Agent shall have no obligation to determine whether delivering such Prospectus is required under
the Securities Act. 

  
 78 

 (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 of such Purchase Contacts 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 which 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. 

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 in the Borough of Manhattan, The
City of New York, New York, maintained for that purpose; provided that, 

  
 79 

 
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 re-creation 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. 

(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 Senior Indebtedness of the Company. The CAP Obligations shall
rank on a parity with (i) the Debentures and all other securities issued under the Base Indenture, and (ii) all other indebtedness and obligations of the Company ranking on parity with the indebtedness described in the foregoing clause
(i). 
 In the event (A) of any insolvency or bankruptcy proceedings or any receivership, liquidation, reorganization or other similar
proceedings in respect of the Company or a substantial part of its property, or of any proceedings for liquidation, dissolution or other winding up of the Company, whether or not involving insolvency or bankruptcy, or (B) subject to the
provisions of Section 1403 of the Base Indenture, that (i) a default shall have occurred with respect to the payment of principal of or interest on or other monetary amounts due and payable on any Senior Indebtedness of the Company and
such default shall have continued beyond the period of grace, if any, in respect thereof, or (ii) there shall have occurred a default (other than a default in the payment of principal or interest or other monetary amounts due and payable) in

  
 80 

 
respect of any Senior Indebtedness of the Company, as defined therein or in the instrument under which the same is outstanding, permitting the holder or holders thereof, to accelerate the
maturity thereof (with notice or lapse of time, or both), and such default shall have continued beyond the period of grace, if any, in respect thereof, and, in the cases of subclauses (i) and (ii) of this clause (B), such default shall not have
been cured or waived or shall not have ceased to exist, or (C) that the principal of and accrued interest on the Securities of any series shall have been declared due and payable pursuant to Section 801 of the Base Indenture and such
declaration shall not have been rescinded and annulled as provided in Section 802 of the Base Indenture, then: 
 (1)
the holders of all Senior Indebtedness of the Company shall first be entitled to receive payment of the full amount due thereon, or provision shall be made for such payment in money or money’s worth, before the Holders of the Units are entitled
to receive a payment on account of the CAP Obligations; 
 (2) any payment by, or distribution of assets of, the Company of
any kind or character, whether in cash, property or securities, to which any Holder of the Units or the Purchase Contract Agent would be entitled except for the provisions of this Section 5.11, shall be paid or delivered by the Person making
such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of such Senior 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 Senior Indebtedness of the Company may have been issued, ratably according to the aggregate amounts remaining unpaid on account of such Senior Indebtedness of the
Company held or represented by each, to the extent necessary to make payment in full of all Senior Indebtedness of the Company remaining unpaid after giving effect to any concurrent payment or distribution (or provision therefor) to the holders of
such Senior Indebtedness of the Company, before any payment or distribution is made to the Holders of the Units or to the Purchase Contract Agent under this Agreement, the Units or the Purchase Contracts on account of the CAP Obligations; and 

(3) in the event that, notwithstanding the foregoing, any payment by the Company on account of the CAP Obligations, shall be
received by the Purchase Contract Agent or any Holder of the Units before all Senior Indebtedness of the Company is paid in full, or provision is made for such payment in money or money’s worth, such payment on account of the CAP Obligations
shall be paid over to the holders of such Senior Indebtedness of the Company or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any such Senior Indebtedness of the
Company may have been issued, ratably as aforesaid, for application to the payment of all Senior Indebtedness of the Company remaining unpaid until all such Senior Indebtedness of the Company shall have been paid in full, after giving effect to any
concurrent payment or distribution (or provision therefor) to the holders of such Senior Indebtedness of the Company. 

  
 81 

 Notwithstanding the foregoing, at any time after the 123rd day following the date of deposit of cash or Eligible Obligations (as defined in the Base Indenture) pursuant to Section 701 or 702 of the Base Indenture (provided all conditions set out in
such Section shall have been satisfied), the funds so deposited and any interest thereon will not be subject to any rights of holders of Senior Indebtedness of the Company including, without limitation, those arising under the provisions of
Section 5.11(d) through (p); provided that no event described in clauses (e) and (f) of Section 801 of the Base Indenture with respect to the Company has occurred during such 123-day period.

 For purposes of the provisions of Section 5.11(d) through (p) only, the words “cash, property or securities” shall
not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment which are subordinate in right of payment to all
Senior Indebtedness of the Company which may at the time be outstanding to the same extent as, or to a greater extent than, the CAP Obligations are so subordinated as provided in this Section 5.11. The consolidation of the Company with, or the
merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article Nine hereof shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of the provisions of Section 5.11(d) through (p) if such
other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article Nine hereof. Nothing in this Section 5.11(d) shall apply to claims of, or payments to, the Purchase Contract
Agent under or pursuant to Section 7.07. 
 (e) Any failure by the Company to make any payment on or perform any other obligation in
respect of Senior Indebtedness of the Company, other than any indebtedness incurred by the Company or assumed or guaranteed, directly or indirectly, by the Company for money borrowed (or any deferral, renewal, extension or refunding thereof) or any
other obligation as to which the provisions of this Section 5.11 shall have been waived by the Company in the instrument or instruments by which the Company incurred, assumed, guaranteed or otherwise created such indebtedness or obligation,
shall not be deemed a default under clause (d) of this Section 5.11 if (i) the Company shall be disputing its obligation to make such payment or perform such obligation and (ii) either (A) no final judgment relating to such
dispute shall have been issued against the Company which is in full force and effect and is not subject to further review, including a judgment that has become final by reason of the expiration of the time within which a party may seek further
appeal or review, or (B) in the event that a judgment that is subject to further review or appeal has been issued, the Company shall in good faith be prosecuting an appeal or other proceeding for review and a stay or execution shall have been
obtained pending such appeal or review. 
 (f) Senior Indebtedness of the Company shall not be deemed to have been paid in full unless the
holders thereof shall have received cash (or securities or other property satisfactory to such holders) in full payment of such Senior Indebtedness of the Company then outstanding. Upon the payment in full of all Senior Indebtedness of the Company,
the rights of the Holders of the Units shall be subrogated to the rights of the holders of Senior Indebtedness of the Company to receive any further payments or distributions of cash, property or securities of the Company

  
 82 

 
applicable to the holders of the Senior Indebtedness of the Company until the CAP Obligations shall be paid in full; and such payments or distributions of cash, property or securities received by
the Holders of the Units, by reason of such subrogation, which otherwise would be paid or distributed to the holders of such Senior Indebtedness of the Company shall, as between the Company, its creditors other than the holders of Senior
Indebtedness of the Company, and the Holders of the Units, be deemed to be a payment by the Company to or on account of Senior Indebtedness of the Company, it being understood that the provisions of the provisions of Section 5.11(d) through
(p) 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 Senior Indebtedness of the Company, on the other hand. 

(g) Nothing contained in the provisions of Section 5.11(d) through (p) or elsewhere in this Agreement, the Units or the Purchase
Contracts is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness of the Company and the Holders of the Units, the obligation of the Company, which is absolute and unconditional, to satisfy
the CAP Obligations as and when the same shall become due and payable in accordance with this Agreement, the Units or the Purchase Contracts, or is intended to or shall affect the relative rights of the Holders and creditors of the Company other
than the holders of Senior Indebtedness of the Company, nor shall anything herein or therein prevent the Purchase Contract Agent or any Holder from exercising all remedies otherwise permitted by applicable law upon a failure of the Company to
satisfy the CAP Obligations under this Agreement, the Units or the Purchase Contracts, subject to the rights, if any, under the provisions of Section 5.11(d) through (p) of the holders of Senior Indebtedness of the Company in respect of
cash, property or securities of the Company received upon the exercise of any such remedy. 
 Upon any payment or distribution of assets or
securities of the Company referred to in the provisions of Section 5.11(d) through (p), the Purchase Contract Agent and the Holders shall be entitled to rely upon any order or decree of a court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness of the Company and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon, and all other facts pertinent thereto or to the provisions of Section 5.11(d) through (p). 

The Purchase Contract Agent shall be entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Indebtedness of the Company (or a representative of such holder or a trustee under any indenture under which any instruments evidencing any such Senior Indebtedness of the Company may have been issued) to establish that such
notice has been given by a holder of such Senior Indebtedness of the Company or such representative or trustee on behalf of such holder. 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 Senior Indebtedness of the Company, to participate in any payment or distribution pursuant to Purchase Contract Agent, 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 Senior Indebtedness of the Company held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts
pertinent to the right of such Person under the provisions of Section 5.11(d) through (p), 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 or distribution. 

  
 83 

 (h) Upon the maturity of the principal of any Senior Indebtedness of the Company by lapse of
time, acceleration or otherwise, all matured principal of Senior Indebtedness of the Company and interest and premium, if any, thereon shall first be paid in full before any payment of the CAP Obligations is made. 

(i) The Purchase Contract Agent in its individual capacity shall be entitled to all rights set forth in the provisions of Section 5.11(d)
through (p) with respect to any Senior Indebtedness of the Company at any time held by it, to the same extent as any other holder of Senior Indebtedness of the Company. Nothing in the provisions of Section 5.11(d) through (p) shall
deprive the Purchase Contract Agent of any of its rights as such holder. 
 Nothing in the provisions of Section 5.11(d) through
(p) shall apply to claims of, or payments to, the Purchase Contract Agent under or pursuant to Section 7.07. 
 (j)
Notwithstanding the provisions of Section 5.11(d) through (p) or any other provision of this Agreement, the Units or the Purchase Contracts, the Purchase Contract Agent shall not 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 the Purchase Contract Agent shall have received written notice thereof at the address specified in Section 1.05 from the Company,
from a Holder or from a holder of any Senior Indebtedness of the Company or from any representative or representatives of such holder or any trustee or trustees under any indenture under which any instruments evidencing any such Senior Indebtedness
of the Company may have been issued and, prior to the receipt of any such written notice, the Purchase Contract Agent shall be entitled, subject to Section 7.01, 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
Section, then, anything herein contained to the contrary notwithstanding, the Purchase Contract Agent shall 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, however, that no such application shall affect the obligations under the provisions of Section 5.11(d) through (p)of the persons receiving such moneys from the
Purchase Contract Agent. 
 (k) The holders of Senior Indebtedness of the Company may, without affecting in any manner the subordination of
the satisfaction CAP Obligations, at any time or from time to time and in their absolute discretion, agree with the Company to change the manner, place or terms of payment, change or extend the time of payment of, or renew or alter, any Senior
Indebtedness of the Company, or amend or supplement any instrument pursuant to which any Senior Indebtedness of the Company is issued, or exercise or refrain from exercising any other of their rights under the Senior Indebtedness of the Company
including, without limitation, the waiver of default thereunder, all without notice to or assent from the Holders or the Purchase Contract Agent. 

  
 84 

 (l) With respect to the holders of Senior Indebtedness of the Company, the Purchase Contract
Agent undertakes to perform or to observe only such of its covenants and objectives as are specifically set forth in this Agreement, the Units or the Purchase Contracts, and no implied covenants or obligations with respect to the holders of Senior
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 Senior Indebtedness
of the Company, and shall not be liable to any such holders if it shall mistakenly pay over or deliver to the Holders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by
virtue of the provisions of Section 5.11(d) through (p) or otherwise. 
 (m) In case at any time any Paying Agent other than the
Purchase Contract Agent shall have been appointed by the Company and be then acting hereunder, the term “Purchase Contract Agent” as used in the provisions of Section 5.11(d) through (p) shall in such case (unless the context
shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in the provisions of Section 5.11(d) through (p) in addition
to or in place of the Purchase Contract Agent; provided, however, that Sections 5.11 (i), (j) and (l) shall not apply to the Company if it acts as Paying Agent. 

(n) No right of any present or future holder of Senior Indebtedness of the Company to enforce the subordination herein shall at any time or in
any way be prejudiced or impaired by any act or failure to act on the part of the Company 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 any such holder may have or be otherwise charged with. 
 (o) Notwithstanding anything contained herein to the contrary,
other than as provided in the immediately succeeding sentence, all the provisions of this this Agreement, the Units or the Purchase Contracts shall be subject to the provisions of Section 5.11(d) through (p), so far as the same may be
applicable thereto. 
 Notwithstanding anything contained herein to the contrary, the provisions of Section 5.11(d) through
(p) shall be of no further effect, and the CAP Obligations shall no longer be subordinated in right of payment to the prior payment of Senior Indebtedness of the Company, if, and to the extent, the Company shall have delivered to the Purchase
Contract Agent a notice to such effect. Any such notice delivered by the Company shall not be deemed to be a supplemental indenture for purposes of Article Twelve of the Base Indenture. 

(p) 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 (p) 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 

  
 85 

 
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 4.825% 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. 

(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 

  
 86 

 
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; 

(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 the Debentures, any preferred trust 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 will not be permitted under this Agreement to make Contract Adjustment Payments in part; or 

  
 87 

 (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 9.01 Covenant Not to Consolidate, Merge, Convey, Transfer or Lease
Property except under Certain Conditions. The Company shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, unless

Company to the Purchase Contract Agent for authentication and execution, and any Certificate evidencing Units which such successor corporation thereafter shall cause to be signed and delivered to the Purchase Contract Agent for that purpose. All the
Certificates issued shall in all respects have the same legal rank and benefit under this Agreement as the Certificates theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Certificates had been

send copies of all statements, confirmations and other correspondence concerning the Collateral Account and any financial assets credited thereto simultaneously to each of the Purchase Contract Agent and the Collateral Agent at their addresses for
notices under this Agreement. 
 Section 12.09 Reserved. 

Section 12.10 No Other Agreements. The Securities Intermediary has not entered into, and prior to the
termination of the Pledge will not enter into, any agreement with any other Person relating to the Collateral Account or any financial assets credited thereto, including, without limitation, any agreement to comply with entitlement orders of any
Person other than the Collateral Agent. 
 Section 12.11 Powers Coupled with an Interest. The rights
and powers granted in this Agreement to the Collateral Agent have been granted in order to perfect its security interests in the Collateral Account, are powers coupled with an interest and will be affected neither by the bankruptcy of the Purchase
Contract Agent or any Holder nor by the lapse of time. The obligations of the Securities Intermediary under this Purchase Contract and Pledge Agreement shall continue in effect until the termination of the Pledge. 

Section 12.12 Waiver of Lien; Waiver of Set-off. The
Securities Intermediary waives any security interest, lien or right to make deductions or set-offs that it may now have or hereafter acquire in or with respect to the Collateral Account, any financial asset
credited thereto or any security entitlement in respect thereof. Neither the financial assets credited to the Collateral Account nor the security entitlements in respect thereof will be subject to deduction,
set-off, banker’s lien, or any other right in favor of any person other than the Company.

interest payments thereon), (ii) Pledged Applicable Ownership Interests in the Treasury Portfolio, or (iii) the Pledged Treasury Securities as provided in this Agreement in satisfaction of the Obligations of the Holder of the Units of which
such Debentures underlying Pledged Applicable Ownership Interests in Debentures, such Pledged Applicable Ownership Interests in the Treasury Portfolio or such Pledged Treasury Securities are a part under the related Purchase Contracts, the inability

Ownership Interests in Debentures, Pledged Treasury Securities or Pledged Applicable Ownership Interests in the Treasury Portfolio, as applicable, any and all of the rights and remedies available to a secured party under the UCC and the TRADES

executing any documents or taking any such acts requested by the Collateral Agent hereunder, except for liability for its own grossly negligent acts, its own grossly negligent failure to act or its own willful misconduct.

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

(b) such Holder is the sole beneficial owner of the Collateral and, in the case of Collateral delivered in physical form, is the sole holder

liability to pay money or other restriction other than the security interest and lien granted under Article XI; 
 (c) upon the Transfer of
the Collateral to the Securities Intermediary for credit to the Collateral Account, the Collateral Agent, for the benefit of the Company, will have a valid and perfected first priority security interest therein (assuming that any central clearing
operation or any securities intermediary or other entity not within the control of the Holder involved in the Transfer of the Collateral, including the Collateral Agent and the Securities Intermediary, gives the notices and takes the action required
of it hereunder and under applicable law for perfection of that interest and assuming the establishment and exercise of control pursuant to Article XII); and 

(d) the execution and performance by the Holder of its obligations under this Agreement will not result in the creation of any security
interest, lien or other encumbrance on the Collateral (other than the security interest and lien granted under Article XI) or violate any provision of any existing law or regulation applicable to it or of any mortgage, charge, pledge, indenture,
contract or undertaking to which it is a party or which is binding on it or any of its assets.

(a) neither the Purchase Contract Agent nor such Holders will create or purport to create or allow to subsist any mortgage, charge, lien,
pledge or any other security interest whatsoever over the Collateral or any part of it other than pursuant to this Agreement; and 

  
 108 

 (b) neither the Purchase Contract Agent nor such Holders will sell or otherwise dispose (or
attempt to dispose) of the Collateral or any part of it except for the beneficial interest therein, subject to the Pledge hereunder, transferred in connection with a Transfer of the Units. 

ARTICLE XV 
 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: 

(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

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. 

  
 109 

 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 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 such Agent deems appropriate; 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 Officer’s 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. 

  
 110 

 (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 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. 

  
 111 

 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 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 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 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: 

  
 112 

 (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. 
 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. 

  
 113 

 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 Borough of Manhattan, The City of New York, New York) with a combined capital and surplus of at least $50,000,000. Upon the acceptance of any appointment as Collateral
Agent, Custodial Agent or Securities Intermediary hereunder by a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, such successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may
be, shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, and the retiring Collateral Agent, Custodial Agent
or Securities Intermediary, as the case may be, shall take all appropriate action, subject to payment of any amounts then due and payable to it hereunder, to transfer any money and property held by it hereunder (including the Collateral) to such
successor. The retiring Collateral Agent, Custodial Agent or Securities Intermediary shall, upon such succession, be discharged from its duties and obligations as Collateral Agent, Custodial Agent or Securities Intermediary hereunder. After any
retiring Collateral Agent’s, Custodial Agent’s or Securities Intermediary’s resignation hereunder as Collateral Agent, Custodial Agent or Securities Intermediary, the provisions of this Article XV 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 XV 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.

  
 114 

 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; 

(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. 

  
 115

2020 Corporate Units 

This Corporate Units Certificate certifies that [Cede & Co.] is the registered Holder of the number of Corporate Units set forth
above [For inclusion in Global Certificates only — or such other number of Corporate Units reflected in the Schedule of Increases or Decreases in Global Certificate attached hereto, which number, taken together with the number of all other
Outstanding Corporate Units and the number of all Outstanding Treasury Units, shall not exceed [___________] Units]. Each Corporate Unit consists of (i) 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 and (ii) either (A) an Applicable Ownership Interest in Debentures or (B) upon the occurrence of a Successful Optional Remarketing during the Optional
Remarketing Period, the Applicable Ownership Interest in the Treasury Portfolio, subject to the pledge of the Applicable Ownership Interest in the Treasury Portfolio (as specified in clause (i) of the definition of Applicable Ownership Interest
in the Treasury Portfolio) by such Holder pursuant to the Purchase Contract and Pledge Agreement. 
 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 Debentures or the Applicable
Ownership Interest in the Treasury Portfolio (as specified in clause (i) of the definition of Applicable Ownership Interest in the Treasury Portfolio), 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 Debentures or distributions with respect to the Applicable Ownership
Interests in the Treasury Portfolio (as specified in clause (ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio), as the case may be, constituting part of the Corporate Units shall be paid on the dates and in the
manner set forth in the Purchase Contract and Pledge Agreement. Interest on the Debentures underlying the Applicable Ownership Interests in Debentures or distributions on the Applicable Ownership Interests in the Treasury Portfolio (as specified in
clause (ii) of the 

  
 A-2 

 
definition of Applicable Ownership Interests in the Treasury Portfolio), 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 (ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio), 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 Debentures underlying the
Pledged Applicable Ownership Interests in Debentures 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. 
 Interest on the Applicable Ownership Interests in Debentures and distributions on the Applicable Ownership
Interests in the Treasury Portfolio (as specified in clause (ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio), to the extent payable to the Holder pursuant to the Purchase Contract and Pledge Agreement, if the
book entry system for the Units has been terminated, will be payable by check mailed to the address of the Holder as it appears on the Security Register or, if the Holder 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. 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 Debentures underlying the Applicable Ownership Interests in Debentures or the Applicable Ownership Interests in the Treasury Portfolio, as the case may be, (ii) to treat the Debentures 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 Debentures and 0% to each Purchase Contract, which will establish each Beneficial Owner’s initial tax basis in each Purchase Contract as $0.00 and
each Beneficial Owner’s initial tax basis in each Applicable Ownership Interest in Debentures as $50.00, 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. 

  
 A-3 

 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 4.825% 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 Senior Indebtedness. 
 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, facsimile or electronic signature, this Corporate Units Certificate shall not be entitled to any benefit under the Purchase Contract and Pledge Agreement or be valid or obligatory for any purpose.

 (REVERSE OF CORPORATE UNITS CERTIFICATE) 

Each Purchase Contract evidenced hereby is governed by the Purchase Contract and Pledge Agreement, dated as of August 14, 2020 (as may be
supplemented from time to time, the “Purchase Contract and Pledge Agreement”), among the Company and The Bank of New York Mellon Trust Company, N.A., 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 (i) of the definition of Applicable Ownership Interest in the Treasury Portfolio), from the proceeds of a Final Remarketing of
the Debentures underlying the Pledged Applicable Ownership Interests in Debentures 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 

  
 A-7 

 
Common Stock to be delivered under the related Purchase Contract (1) in the case of a Successful Final Remarketing, from the proceeds of the sale of the Debentures underlying the Pledged
Applicable Ownership Interests in Debentures held by the Collateral Agent in the Final Remarketing, (2) in the case of a Successful Optional Remarketing, from the proceeds at maturity of the Applicable Ownership Interests in the Treasury
Portfolio (as specified in clause (i) of the definition of Applicable Ownership Interests in the Treasury Portfolio) 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 Debentures, 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 Debentures underlying such Applicable Ownership Interests in Debentures 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 Debentures underlying the Pledged
Applicable Ownership Interests in Debentures or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (i) of the definition of such term) 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 Debentures underlying the Applicable Ownership Interest in the Debentures 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures to the extent instructed in writing by the Holders.
Upon receipt of notice of any meeting at which holders of Debentures 

  
 A-8 

 
are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Debentures, 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. 
 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 Treasury Portfolio Purchase Price to purchase the Treasury Portfolio. 
 Following the occurrence of a
Successful Optional Remarketing, 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 (i) of the definition of such
term) as the Collateral Agent had in respect of Applicable Ownership Interests in Debentures and the underlying Debentures, subject to the Pledge thereof as provided in the Purchase Contract and Pledge Agreement and any reference herein to the
Debentures or Applicable Ownership Interests in Debentures 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 Debentures underlying the Applicable Ownership Interests in Debentures, 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 Debentures, 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 Debentures as a component of the Corporate Units, in integral multiples of 160,000 Corporate Units. 

  
 A-9 

 Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Debentures
underlying the Pledged Applicable Ownership Interests in Debentures or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (i) of the definition of such term) 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 Debentures as a component of the Corporate Units, in integral multiples of 160,000 Corporate Units. Upon Fundamental Change Early Settlement of Purchase Contracts by a Holder of the related Corporate Units, the
Debentures underlying the Pledged Applicable Ownership Interests in Debentures or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (i) of the definition of such term) 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 Debentures and the underlying Debentures or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (i) of the definition of Applicable Ownership Interests in
the Treasury 

  
 A-10 

 
Portfolio), 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 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 Debentures underlying the Pledged Applicable Ownership Interests in Debentures (other than interest payments thereon) or the Proceeds of the Applicable Ownership Interests in
the Treasury Portfolio (as specified in clause (i) of the definition of Applicable Ownership Interests in the Treasury Portfolio), 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 Debentures underlying the Applicable Ownership Interests in Debentures, the Applicable
Ownership Interests in the Treasury Portfolio (as specified in clause (ii) of the definition thereof) 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.

 AMERICAN ELECTRIC POWER COMPANY, INC. 

2020 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 [__________] Units].
Each Treasury Unit consists of (i) a 1/20 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 (i) 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 and (ii) in all events, not take any position for U.S. federal, state or local income tax purposes that is inconsistent with or contrary to the above covenant. 

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 4.825% 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 Senior Indebtedness. 
 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, facsimile or electronic signature, this Treasury Units Certificate shall not be entitled to any benefit under the Purchase Contract and Pledge Agreement or be valid or obligatory for any purpose.

 (REVERSE OF TREASURY UNITS CERTIFICATE) 

Each Purchase Contract evidenced hereby is governed by a Purchase Contract and Pledge Agreement, dated as of August 14, 2020 (as may be
supplemented from time to time, the “Purchase Contract and Pledge Agreement”) among the Company and The Bank of New York Mellon Trust Company, N.A., 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-6 

 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 Debentures
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 Debentures 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-7 

 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-8 

 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.

and in the Purchase Contract and Pledge Agreement and the Supplemental Indenture, the Reset Rate for the Debentures, and (iii) performing such other duties as are assigned to the Remarketing Agent in the Transaction Documents. 

(b) Unless a Termination Event has occurred prior to such date, if the Company elects to conduct an Optional Remarketing during the Optional
Remarketing Period selected by the Company pursuant to the Purchase Contract and Pledge Agreement, the Remarketing Agent shall use its commercially reasonable efforts to remarket the Remarketed Debentures at the applicable Remarketing Price. For the
avoidance of doubt, the Company shall determine in its sole discretion if and when to attempt an Optional Remarketing, as the Company may commence or postpone or cancel an Optional Remarketing in its absolute and sole discretion. In the case of an
Optional Remarketing, on any Remarketing Date, the Remarketing Agent shall notify the Company, the Collateral Agent and the Quotation Agent of the amount and issue of the U.S. Treasury securities (or principal or interest strips thereof) that will

 P-4 

 (c) If there is no Successful Optional Remarketing during the Optional Remarketing Period or
no Optional Remarketing occurs on any Optional Remarketing Date, if any, and unless a Termination Event has occurred prior to such date, on each Remarketing Date in the Final Remarketing Period, the Remarketing Agent shall use its commercially
reasonable efforts to remarket the Remarketed Debentures at the applicable Remarketing Price. It is understood and agreed that the Remarketing on any Remarketing Date in the Final Remarketing Period will be considered successful if the resulting
proceeds are at least equal to the applicable Remarketing Price. 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 two Business Days of the Final Remarketing
Period. 
 (d) In connection with a Remarketing, the Remarketing Agent shall determine, in consultation with the Company, the rate per
annum, rounded to the nearest one-thousandth (0.001) of one percent per annum, or, if the Company elects to remarket the Debentures as floating-rate Debentures as described in Section 2(i)(3), the index
rate plus spread that the Remarketed Debentures should bear (such fixed or floating rate, the “Reset Rate”) in order for the Remarketed Debentures to have an aggregate market value equal 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 Debentures 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 Debentures, 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
Debentures 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 Debentures and the aggregate principal amount of Remarketed Debentures sold in such Remarketing; 

(ii) each purchaser (or the Depository Participant thereof) of Remarketed Debentures of the Reset Rate and the aggregate
principal amount of Remarketed Debentures such purchaser is to purchase; 

  
 P-5 

 (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 Debentures purchased through the facilities of the Depository; and 

(iv) each such purchaser (or Depository Participant thereof) that the Remarketed Debentures will not be delivered until the
Remarketing Settlement Date and (if applicable) that if such purchaser wishes to trade the Remarketed Debentures 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 Debentures underlying the Applicable Ownership Interests in
Debentures that are components of the Corporate Units and (ii) with respect to the Separate Debentures, 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 Debentures,
whether in the Remarketing or otherwise, and shall in no way be obligated to provide funds to make payment upon surrender of Remarketed Debentures 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 Debentures for Remarketing. 

(i) Notwithstanding anything to the contrary herein, it is understood and agreed that in connection with any Remarketing, the Company may
elect, in consultation with the Remarketing Agent to, among other things, remarket the Debentures as fixed-rate notes or floating-rate notes and, in the case of floating-rate notes, provide that the interest rate on the Debentures shall be equal to
an index selected by the Company plus a spread determined by the Remarketing Agent, in consultation with the Company, in which case interest on the Debentures may be calculated on the basis of a 365 day year and the actual number of days elapsed (or
such other basis as is customarily used for floating-rate notes bearing interest at a rate based on such index rate).

the Remarketing Agent; and not file any such amendment or supplement that shall be reasonably disapproved by the Remarketing Agent; 

(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 

  
 P-12 

 (xi) take such action as the Remarketing Agent may reasonably request in
order to qualify the Remarketed Debentures 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 Debentures; 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. 
 (xii) 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 Debentures
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 Debentures; (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 Debentures (such fees and expenses not to exceed $[_____]). 

(b) 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.

 (c) 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 Debentures. 

  
 P-13 

 (d) 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 Debentures 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
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. 

(e) The Company will prepare a final term sheet relating to the Remarketed Debentures, containing only information that describes the final
terms of the Remarketed Debentures 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 Debentures. Any such final term
sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. 
 Section 6. CONDITIONS TO THE
REMARKETING AGENT’S OBLIGATIONS. 
 The obligations of the Remarketing Agent hereunder shall be subject to the following
conditions: 
 (a) If the Registration Covenants are applicable, no stop order with respect to the effectiveness of the Registration

 (b) Subsequent to the
Commencement Date, there shall not have been any material adverse change in the business, properties or financial condition of the Company (“Material Adverse Change”) from that set forth in the Disclosure Package or the Registration
Statement (other than changes referred to in or contemplated by the Disclosure Package), and that the Company shall have furnished to the Remarketing Agent a certificate of an executive officer of the Company, dated the applicable Remarketing
Settlement Date, to the effect that, to the best of his or her knowledge, information and belief, there has been no such 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. 

  
 P-14 

 (d) The Company shall have furnished to the Remarketing Agent a written certificate executed
by an authorized officer of the Company, dated the applicable Remarketing Settlement Date, to the effect of the following and as to such other matters as the Representatives may reasonably request, to the best of his or her knowledge:

Registration Statement, and no proceedings for that purpose or pursuant to Section 8A of the Securities Act have been instituted or threatened by the Commission; 

(ii) subsequent to the Commencement Date and prior to the applicable Remarketing Date, there has not occurred any downgrading
in the rating accorded to the Company’s senior debt securities by any nationally recognized statistical rating organization, as defined in Section 3(a)(62) of the Securities Exchange Act, that rated the senior debt securities as of the
Commencement 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. 
 (e) On the date of a
Successful Remarketing and on the Remarketing Settlement Date, the Remarketing Agent shall have received a letter addressed to the Remarketing Agent and dated each such date, in form and substance satisfactory to the Remarketing Agent, of the
independent accountants of the Company who have certified the consolidated financial statements of the Company and its 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 internal counsel shall have furnished to the Remarketing Agent their opinion letter
with respect to the Remarketed Debentures, addressed to the Remarketing Agent and dated the applicable Remarketing Settlement Date, addressing such matters with respect to the Debentures as are set forth in such counsels’ opinion letters
furnished pursuant to Section [ ] of the Underwriting Agreement, adapted as necessary to relate to the securities being remarketed hereunder and to the Remarketing Materials, if any, or to any changed circumstances or events occurring subsequent to
the date of this Agreement, such adaptations being reasonably acceptable to counsel to the Remarketing Agent. 
 (g) The counsel for the
Remarketing Agent shall have furnished to the Remarketing Agent its opinion, addressed to the Remarketing Agent and dated as of the applicable Remarketing Settlement Date, addressing such matters as are set forth in such counsel’s opinion
furnished pursuant to Section [ ] of the Underwriting Agreement, adapted as necessary to relate to the securities being remarketed hereunder and to the Remarketing Materials, if any, or to any changed circumstances or events occurring subsequent to
the date of this Agreement, such adaptations being reasonably acceptable to the Remarketing Agent. 

  
 P-15 

 (h) Subsequent to the Commencement Date and prior to the applicable Remarketing Settlement
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) To
the extent permitted by law, the Company agrees to indemnify and hold harmless the Remarketing Agent, its employees, agents, officers and directors and each person, if any, who controls the Remarketing Agent within the meaning of Section 15 of
the Securities Act, against any and all losses, claims, damages or liabilities to which it may become subject under the Securities Act or otherwise and to reimburse the Remarketing Agent for any legal or other expenses incurred by the Remarketing
Agent in connection with defending any action, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any alleged untrue statement or untrue statement of a material fact contained in the Registration
Statement, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, any related preliminary prospectus supplement (or contained in the 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 arise out of or are based upon any alleged omission or omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such alleged untrue statement or omission, or untrue statement or
omission which was made in the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, any related preliminary prospectus supplement (or contained in the 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 information furnished in
writing to the Company by the Remarketing Agent expressly for use therein or with any statements in or omissions from that part of the Registration Statement that shall constitute the Statement of Eligibility under the Trust Indenture Act of the
Trustee under the Indenture 
 (b) The Remarketing Agent agrees promptly after its receipt of written notice of the commencement of any
action in respect to which indemnity or contribution from the Company on account of its agreement contained in Section 7 or Section 8 hereof may be sought the Remarketing Agent, or by any person controlling such Remarketing Agent, to
notify the Company in writing of the commencement thereof, but the omission so to notify the Company of 

  
 P-16 

 
any such action shall not release the Company from any liability which it may have to the Remarketing Agent or to such controlling person otherwise than on account of the indemnity and
contribution agreement contained in this Agreement. In case any such action shall be brought against the Remarketing Agent or any such controlling person and the Remarketing Agent shall notify the Company of the commencement thereof, as above
provided, the Company shall be entitled to participate in, and, to the extent that it shall wish, including the selection of counsel (such counsel to be reasonably acceptable to the indemnified party), to direct the defense thereof at its own
expense. In case the Company elects to direct such defense and select such counsel (hereinafter, Company’s counsel), the Remarketing Agent or any controlling person shall have the right to employ its own counsel, but, in any such case, the fees
and expenses of such counsel shall be at such Remarketing Agent’s or controlling person’s expense unless (i) the Company has agreed in writing to pay such fees and expenses or (ii) the named parties to any such action (including
any impleaded parties) include both the Remarketing Agent or any controlling person and the Company and such Remarketing Agent or any controlling person shall have been advised by its counsel that a conflict of interest between the Company and such
Remarketing Agent or any controlling person may arise (and the Company’s counsel shall have concurred in good faith with such advice) and for this reason it is not desirable for the Company’s counsel to represent both the indemnifying
party and the indemnified party (it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for the Remarketing Agent or any controlling person (plus any local counsel retained by the Remarketing Agent or any controlling
person in their reasonable judgment), which firm (or firms) shall be designated in writing by the Remarketing Agent or any controlling person). 

(c) The Remarketing Agent agrees, to the extent permitted by law, to indemnify, hold harmless and reimburse the Company, its directors and
such of its officers as shall have signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, to the same extent and upon the same terms as the indemnity
agreement of the Company set forth in Section 7(a) hereof, but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement, any Issuer Free Writing Prospectus, the
Prospectus or any amendment or supplement thereto, any related preliminary prospectus supplement (or contained in the 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 information furnished in writing to the Company by the Remarketing Agent expressly for use therein. The Company agrees
promptly after the receipt by it of written notice of the commencement of any action in respect to which indemnity from the Remarketing Agent on account of the Remarketing Agent’s agreement contained in this Agreement may be sought by the
Company, or by any person controlling the Company, to notify the Remarketing Agent in writing of the commencement thereof, but the Company’s omission so to notify the Remarketing Agent of any such action shall not release the Remarketing Agent
from any liability which it may have to the Company or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 7(b). 

  
 P-17 

 (d) 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 Agreement (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 such indemnified
party. 
 (e) In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of,
or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent. 

(f) The indemnity and contribution agreements contained in this Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of the Remarketing Agent or the Company, or the delivery of and any payment for any Remarketed Debentures hereunder, and shall survive the termination or cancellation of this Agreement 

Section 8. CONTRIBUTION. 
 If
recovery is not available or insufficient to hold the indemnified party harmless under Section 7(a) or 7(b) hereof for any reason other than as specified therein, the indemnified party shall be entitled to contribution for any and all losses,
claims, damages, liabilities and expenses for which such indemnification is so unavailable or insufficient under this Section 8. In determining the amount of contribution to which such indemnified party is entitled, there shall be considered
the portion of the proceeds of the offering of the Remarketed Debentures realized by the Company on the one hand and the Remarketing Agent on the other hand, the relative knowledge and access to information concerning the matter with respect to
which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any equitable considerations appropriate under the circumstances. The Company and the Remarketing Agent agree that it would not be equitable if the
amount of such contribution were determined by pro rata or per capita allocation without reference to the considerations called for in the previous sentence. The Remarketing Agent or any person controlling the Remarketing Agent shall not be
obligated to contribute any amount or amounts hereunder which in the aggregate exceeds the total price of the Remarketed Debentures sold by or through the Remarketing Agent under this Agreement, less the aggregate amount of any damages which the
Remarketing Agent and its controlling persons have otherwise been required to pay in respect of the same claim or any substantially similar claim. 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 who was not guilty of such fraudulent misrepresentation. 
 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 

  
 P-18 

 
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 Debentures, 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
Debentures 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. 
 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 Remarketing Transaction
Documents, and the Remarketing Agent shall not be responsible for the performance of any other duties and obligations than as are specifically set forth in the Transaction Documents, and no implied covenants or obligations shall be read into the
Transaction Documents against the Remarketing Agent. The Remarketing Agent may conclusively rely upon any notice or document given or furnished to the Remarketing Agent and conforming to the requirements of the Transaction Documents and shall be
protected in acting upon any such notice or document reasonably believed by it to be genuine and to have been given, signed or presented 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 Debentures or, if there is any such limitation, the maximum permissible Reset Rate on the Debentures, 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 Debentures 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. 

  
 P-19 

 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 Debentures 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 Debentures 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 Debentures, but the Company shall then be under no further liability to the Remarketing Agent with respect to such failed settlement of the Remarketed Debentures except as provided in Sections 5(b), 7 and 8. 

Section 14. [RESERVED]. 
 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.

Agreement.

GENERAL TERMS AND CONDITIONS OF THE DEBENTURES 

Section 2.01 Designation and Principal Amount. There is hereby authorized a new series of Securities, to be designated the
“1.30% Junior Subordinated Debentures due 2025,” (the “Debentures”) in the initial aggregate principal amount of $850,000,000, which amount shall be set forth in any written orders of the Company for the authentication and
delivery of Debentures pursuant to Section 301 of the Base Indenture and Section 6.01 hereof. For the avoidance of doubt, no additional Debentures may be issued following the Original Issue Date, except as expressly
set forth in the first sentence of this Section 2.01. 
 Section 2.02 Stated Maturity. The
“Stated Maturity” of the Debentures is August 15, 2025. For the avoidance of doubt, with respect to the Debentures, the term “Stated Maturity” refers only to the date on which principal is due and payable as set forth
in this Section 2.02. 
 Section 2.03 Form and Payment; Minimum Transfer Restriction. 

(a) Except as provided in Section 2.04, the Debentures shall be issued in fully registered definitive form without
coupons. All Debentures shall have identical terms. Debentures corresponding to Applicable Ownership Interests in Debentures that are components of Corporate Units shall be registered in the name of the Purchase Contract Agent. Principal of the
Debentures will be payable (subject to the last sentence of this Section 2.03(a)), the transfer of such Debentures will be registrable, and such Debentures will be exchangeable for Debentures of a like aggregate principal
amount bearing identical terms and provisions, at the Corporate Trust Office of the Trustee; provided, however, that, except as otherwise provided in the form of Debenture attached hereto as Exhibit A, payment of interest will be made
by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or, if such Person so requests and designates an account in writing to the Trustee at least five Business Days prior to the relevant
Interest Payment Date, by wire transfer to such account, and provided, further, that the Company, in its discretion may remove the Paying Agent and may appoint one or more additional Paying Agents (including the Company or any of its
affiliates). Payments with respect to any Global Debenture or any Debenture corresponding to Applicable Ownership Interests in Debentures that are components of Corporate Units will be made by wire transfer to the Depository or in accordance with
any other applicable procedures of the Depository. 
 (b) The Debentures shall be issuable in minimum denominations of $1,000 and integral
multiples of $1,000 in excess thereof; provided, however, that upon the release by the Collateral Agent of Debentures underlying the Pledged Applicable Ownership Interests in Debentures in accordance with Section 3.15 of the
Purchase Contract and Pledge Agreement, if any Holder or Beneficial Owner shall be entitled to receive Debentures in an aggregate principal amount that is not an integral multiple of $1,000, the Purchase Contract Agent may request, on behalf of such
Holder or Beneficial Owner, that the Company issue Debentures in denominations of $50, or integral multiples thereof, in exchange for Debentures in denominations of $1,000 or integral multiples thereof. Section 302 of the Base Indenture

  
 4 

 
shall not apply with respect to the Debentures, and any reference in the Base Indenture to such provision shall, for purposes of the Debentures, be deemed to refer instead to this
Section 2.03(b). 
 Section 2.04 Exchange and Registration of Transfer of Debentures; Restrictions on
Transfers; Depositary. Debentures corresponding to Applicable Ownership Interests in Debentures that are no longer a component of the Corporate Units and are released from the Collateral Account will be initially issued in permanent global form
(a “Global Debenture”), and if issued as one or more Global Debentures, the Depository shall be The Depository Trust Company or such other depository that is a clearing agency registered under Section 17A of the Exchange Act as
any officer of the Company may from time to time designate. On the date on which the Debentures registered in the name of the Purchase Contract Agent pursuant to Section 2.03 are issued, the Company shall also issue one or
more Global Debentures, registered in the name of the Depository or its nominee, each having a zero principal balance. Upon the creation of Treasury Units, or the re-creation of Corporate Units or in any other
case where the Collateral Agent releases Debentures underlying the Pledged Applicable Ownership Interests in Debentures, an appropriate annotation shall be made on the Schedule of Increases or Decreases in Debentures on the Global Debentures held by
the Depository and on the Pledged Debenture (as defined below) held by the Collateral Agent. Except upon recreation of Corporate Units, Debentures represented by the Global Debentures will be exchangeable for Debentures in certificated form only
(x) if the Depository (A) has notified the Company that it is unwilling or unable to continue as depository for the Global Debentures or (B) has ceased to be a “clearing agency” registered under the Exchange Act and, in
either case, a successor depository that is a clearing agency registered under Section 17A of the Exchange Act is not appointed by the Company within 90 days after such notice or cessation, or (y) upon the occurrence and during the
continuance of an Event of Default or any other event that after notice or lapse of time, would constitute an Event of Default with respect to the Debentures and any beneficial owner of a Global Debenture requests that its beneficial interest be
exchanged for a Debenture in certificated form; provided, subject to Section 2.03, that the Debentures in certificated form so issued in exchange for the Global Debentures shall be in denominations of $1,000 or any whole
multiple of $1,000 above that amount and shall be of like aggregate principal amount and tenor as the portion of the Global Debenture to be exchanged. Except as provided above, owners of a beneficial interest in a Global Debenture will not be
entitled to receive physical delivery of Debentures in certificated form and will not be considered the Holders thereof for any purpose under the Indenture. Any Global Debenture that is exchangeable pursuant to clause (x) of the fourth
sentence of this Section 2.04 shall be exchangeable for Debentures in certificated form registered in such names as the Depository shall direct. 

Section 2.05 Interest. 

(a) Subject to Article IV and Section 9.04, interest on the Debentures shall be payable quarterly in arrears
on February 15, May 15, August 15 and November 15 of each year (each, subject to adjustment in accordance with Section 2.05(b), an “Interest Payment Date”), commencing November 15,
2020 and at maturity, whether Stated Maturity or otherwise, to the Person in whose name the relevant Debentures are registered at the close of business on the Regular Record Date for such Interest Payment Date except that interest payable at the
Stated Maturity shall be paid to the Person to whom principal is payable. Interest shall be calculated on the basis of a 360-day year of twelve 30-day months, and with
respect to any period less than a full calendar month, on the basis of the actual number of days elapsed during the period. If any Interest Payment Date, the Stated Maturity or the date (if any) on which the Company is required to purchase the
Debentures pursuant to Section 9.05 is not a Business Day, then the applicable payment shall be made on the next succeeding day that is a Business Day and no interest shall accrue or be paid in respect of such delay.
Section 113 of the Base Indenture is hereby superseded in its entirety, with respect to the Debentures, by the immediately preceding sentence. 

  
 5 

 (b) The Debentures will bear interest initially at the rate of 1.30% per year (the
“Coupon Rate”) from and including August 14, 2020, to, but excluding, the date the principal amount thereof is paid or made available for payment, or in the event of a Successful Remarketing, the Remarketing Settlement Date. In the
event of a Successful Remarketing of the Debentures, the interest rate applicable to the Debentures may be reset by the Remarketing Agent(s) to the applicable Reset Rate with effect from the Remarketing Settlement Date, as set forth in
Section 9.03. If the interest rate is so reset, the Debentures will bear interest at the applicable Reset Rate from, and including, the Remarketing Settlement Date to, but excluding, the date the principal amount thereof is
paid or made available for payment. In the event of a Successful Remarketing, following the applicable Remarketing Settlement Date, interest on Debentures will be payable semi-annually on February 15 and August 15 and, if the Debentures
are remarketed as floating-rate notes, interest on the Debentures will be payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, or if any such date is not a Business Day, on the next
following Business Day. If the Company remarkets the Debentures as floating-rate notes, without the consent of any Holder of Debentures, the Company may modify the Interest Payment Dates to provide that if any February 15, May 15,
August 15 and November 15 is not a Business Day, the relevant Interest Payment Date shall be the immediately succeeding Business Day. If there is no Successful Remarketing, the interest rate will not be reset, the Interest Payment Dates
shall remain the same and the Debentures shall continue to bear interest at the Coupon Rate. The Debentures shall bear interest, to the extent permitted by law, on any overdue principal and interest at the Coupon Rate, unless a Successful
Remarketing shall have occurred, in which case on and after the Remarketing Settlement Date the Debentures shall bear interest, to the extent permitted by law, on any overdue principal and interest at the Reset Rate. Section 307 of the Base
Indenture shall not apply with respect to the Debentures, and any reference in the Base Indenture to such provision shall, for purposes of the Debentures, be deemed to refer instead to this Section 2.05. 

Section 2.06 Events of Default. 

Any Event of Default as defined in the Base Indenture shall be an Event of Default with respect to the Debentures; provided that the
nonpayment of interest for so long as and to the extent that interest is permitted to be deferred pursuant to Article IV herein shall not be deemed to be a default in the payment of interest for the purposes of Article VIII of the Base
Indenture and shall not otherwise be deemed an Event of Default with respect to the Debentures. 
 In addition, an Event of Default with
respect to the Debentures will occur if the Company fails to pay the Put Price of any Debenture on the Purchase Contract Settlement Date after a Holder’s Put Right has been exercised pursuant to Section 9.05
(“Put Right Default”). For the avoidance of doubt, and without prejudice to any other remedies that may be available to the Trustee or the Holders of the Debentures, no breach by the Company of any covenant or obligation under the
Base Indenture or the terms of the Debentures shall be an Event of Default except those that are specifically identified as an Event of Default under the Base Indenture (including, for the avoidance of doubt in Section 801(c) of the Base
Indenture) or a Put Right Default. 
 Section 2.07 No Defeasance. Prior to the Purchase Contract Settlement Date, the provisions
of Section 701 of the Base Indenture shall not apply to the Debentures. 
 Section 2.08 No Sinking Fund or Repayment at Option
of the Holder. The Debentures shall not be subject to any sinking fund or analogous provision and, except in the case of the Put Right, shall not be repayable at the option of a Holder thereof prior to the Stated Maturity. 

Section 2.09 Increase and Decrease in Pledged Debentures. In the event that any Debentures underlying Pledged Applicable Ownership
Interests in Debentures with respect to any Corporate Units in 

  
 6 

 
global form are to be released from the Pledge following a Termination Event, Collateral Substitution, Cash Settlement, Successful Remarketing, Early Settlement or Fundamental Change Early
Settlement pursuant to the Purchase Contract and Pledge Agreement (a “Released Debenture”), such release and delivery shall be evidenced by an endorsement by the Collateral Agent on the Debenture held by the Collateral Agent (the
“Pledged Debenture”) reflecting a reduction in the principal amount of such Pledged Debenture equal in amount (the “Reduced Principal Amount”) to the principal amount of the Released Debenture. The Collateral Agent
shall confirm any such Reduced Principal Amount by telecopying or otherwise delivering a photocopy of such endorsement made on the Pledged Debenture evidencing such Reduced Principal Amount to the Trustee at the telecopier number or address of the
Trustee provided for notices to the Trustee Section 12.06 (or at such other telecopier or address as the Trustee shall provide to the Collateral Agent). Upon receipt of such confirmation, the Trustee shall increase the
principal amount of a Global Debenture held by the Trustee in an amount equal to the Reduced Principal Amount by an endorsement made by the Trustee on such Global Debenture to reflect such increase. In the event that a Debenture is transferred to
the Collateral Agent pursuant to Section 3.14 of the Purchase Contract and Pledge Agreement (a “Subjected Debenture”) in connection with the re-creation of Corporate Units, such transfer
shall be evidenced by an endorsement by the Collateral Agent on the Pledged Debenture held by the Collateral Agent reflecting an increase in the principal amount of such Pledged Debenture equal in amount (the “Increased Principal
Amount”) to the principal amount of such Subjected Debenture. The Collateral Agent shall confirm any such Increased Principal Amount by telecopying or otherwise delivering a photocopy of such endorsement made on the Pledged Debenture
evidencing such Increased Principal Amount to the Trustee at the telecopier number or address of the Trustee provided for notices to the Trustee in Section 12.06 (or at such other telecopier or address as the Trustee shall
provide to the Collateral Agent). Upon receipt of such confirmation, the Trustee shall decrease the principal amount of the Global Debenture held by the Trustee in an amount equal to the Increased Principal Amount by an endorsement made by the
Trustee on such Global Debenture to reflect such decrease. 
 Section 2.10 No Additional Amounts. The Company will not pay any
additional amounts to any Holder in respect of any tax, assessment or governmental charge. 
 Section 2.11 Reserved. 

Section 2.12 Reserved. 

Section 2.13 Reserved. 

Section 2.14 Reserved. 

Section 2.15 Ranking; Subordination. For the avoidance of doubt, the Debentures shall rank on a parity with all Securities of
other series issued under the Base Indenture, as well as the CAP Obligations.

 ARTICLE IV

 OPTION TO DEFER INTEREST PAYMENTS 

Section 4.01 Option to Defer Interest Payments. 

(a) The Company may elect at one or more times to defer payment of interest on the Debentures (such unpaid interest, the “Deferred
Interest”) for one or more consecutive Interest Periods; 

  
 7 

 
provided that the interest payable on the Purchase Contract Settlement Date or the Stated Maturity may not be deferred, and no Interest Payment may be deferred beyond the Purchase Contract
Settlement Date, in the case of a Deferral Period that begins prior to the Purchase Contract Settlement Date, or the Stated Maturity, in the case of a Deferral Period that begins after the Purchase Contract Settlement Date. Furthermore, in the event
of a Successful Remarketing, following the applicable Remarketing Settlement Date, the Company shall have no right to defer the payment of interest on the Debentures. If all Deferred Interest has been paid (including compounded interest thereon) and
the Company still has the right to defer the payment of interest, the Company may again defer Interest Payments subject to and in accordance with the terms of this Section 4.01. 

(b) Deferred Interest on the Debentures will bear interest at the interest rate applicable to the Debentures, and subject to applicable law,
such interest will be compounded on each Interest Payment Date to, but excluding, the Interest Payment Date on which such Deferred Interest is paid. 

(c) If a Deferral Period is continuing with respect to the Debentures or the Company has given notice of a Deferral Period but such Deferral
Period has not yet commenced, then until all Deferred Interest (including compounded interest thereon) has been paid, the Company will not: 

(i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares
of its Capital Stock; 
 (ii) make any payment of principal of, or interest or premium, if any, on, or repay, repurchase or redeem any of
its debt securities ranking on a parity with, or ranking junior to, the Debentures (including debt securities of other series issued under the Base Indenture); or 

(iii) make any guarantee payments on any guarantee of debt securities if the guarantee ranks on a parity with or junior to the Debentures.

 (d) However, the foregoing provisions of Section 4.01(c) shall not prevent or restrict the Company from making:

 (i) purchases, redemptions or other acquisitions of its 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 its obligations pursuant to any contract or security outstanding on the
date that the payment of interest is deferred requiring it to purchase, redeem or acquire its Capital Stock; 
 (ii) any payment,
repayment, redemption, purchase, acquisition or declaration of dividends described in clause (c)(i) above as a result of a reclassification of its Capital Stock, or the exchange or conversion of all or a portion of one class or series of its
Capital Stock for another class or series of its Capital Stock; 
 (iii) the purchase of fractional interests in shares of its Capital
Stock pursuant to the conversion or exchange provisions of its 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 payment of interest is
deferred; 
 (iv) dividends or distributions paid or made in its Capital Stock (or rights to acquire its Capital Stock), or repurchases,
redemptions or acquisitions of Capital Stock in connection with 

  
 8 

 
the issuance or exchange of Capital Stock (or of securities convertible into or exchangeable for shares of its Capital Stock) and distributions in connection with the settlement of stock purchase
contracts outstanding on the date that the payment of interest 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 payment of interest 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 the Debentures, 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 Debentures, so long as the amount of payments made on account of such securities or guarantees is paid on all such securities and guarantees
then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities and guarantees is then entitled if paid in full; provided that, for the avoidance of doubt, the Company will not be
permitted under the Indenture to make interest payments on the Debentures in part; or 
 (vii) any payment of deferred interest or
principal on, or repayment, redemption or repurchase of, securities ranking on a parity with or ranking junior to the Debentures that, if not made, would cause the Company to breach the terms of the instrument governing such parity or junior
securities. 
 (e) In the event that the Company elects to defer any Interest Payment, the Company shall notify the Trustee and the Holders
in writing of such election at least one Business Day prior to the Regular Record Date for the Interest Payment Date on which the Company intends to begin a Deferral Period; provided, however, that the Company’s failure to pay the
interest owed on a particular Interest Payment Date shall also constitute the commencement of a Deferral Period, unless such interest is paid within five Business Days after such Interest Payment Date, whether or not the Company provides a notice of
deferral. 
 (f) The Company may pay Deferred Interest (including compounded interest thereon) in cash on any scheduled Interest Payment
Date occurring on or prior to (i) the Purchase Contract Settlement Date, in the case of a Deferral Period that begins prior to the Purchase Contract Settlement Date, or (ii) the Stated Maturity, in the case of a Deferral Period that begins
after the Purchase Contract Settlement Date; provided that in order to end a Deferral Period on any scheduled Interest Payment Date other than the Purchase Contract Settlement Date or the Stated Maturity, the Company must deliver written
notice thereof to Holders of the Debentures and the Trustee on or before the relevant Regular Record Date. Deferred Interest paid on any Interest Payment Date shall be payable to the Person in whose name the Debentures are registered at the close of
business on the Regular Record Date next preceding such Interest Payment Date. 
 (g) In the event there is any Deferred Interest
outstanding, the Company may not elect to conduct an Optional Remarketing. 
 (h) Notwithstanding anything to the contrary herein, in
connection with any Successful Final Remarketing of the Debentures, all accrued and unpaid Deferred Interest (including compounded interest thereon), calculated to, but excluding, the Purchase Contract Settlement Date at the Coupon Rate, shall be
paid to the Holders of Debentures (whether or not such Debentures were remarketed in such Remarketing), as of the applicable Regular Record Date, on the Purchase Contract Settlement Date in cash.

may from time to time, and at any time enter into an indenture or indentures supplemental hereto to amend the Indenture and the Debentures, in form satisfactory to the Trustee (which shall comply with the provisions of the Trust Indenture Act as

 (a)
following the Purchase Contract Settlement Date, to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of the Debentures pursuant to Section 701 of the
Base Indenture, provided that any such action shall not adversely affect the interests of any Holder in any material respect; 
 (b)
to modify Section 2.15 hereof in a manner not materially adverse to the rights of the Holders, it being understood that any modification of the terms of the Debentures permitted pursuant to
Section 9.04 in connection with a Remarketing that is made in accordance with the terms of the Indenture may be made without the consent of any Holders of the Debentures; or 

(c) to amend the Debentures, the Base Indenture (insofar as it relates to the Debentures) and the Indenture to conform the provisions thereof
or hereof to the descriptions thereof or hereof contained in the preliminary prospectus supplement dated August 11, 2020 for the Equity Units, as supplemented by any free writing prospectus used in connection with the offering of the Equity Units,
under the sections entitled “Description of the Equity Units,” “Description of the Purchase Contracts,” “Certain Provisions of the Purchase Contract and Pledge Agreement” and “Description of the Junior Subordinated
Debentures.” 
 The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make
any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, mortgage, pledge or assignment of any property thereunder, but the Trustee shall not be obligated to enter into any such
supplemental indenture which affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

Section 1201 of the Base Indenture shall apply, as amended, with respect to the Debentures, and any reference in the Base Indenture to

an indenture or indentures supplemental hereto or to the Base Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Base Indenture or this Supplemental Indenture No. 2 or of
modifying in any manner the rights of the Holders of the Debentures; provided, however, that, in addition to the restrictions set forth in the proviso contained in Section 1202 of the Base Indenture (which shall apply to this
Section 8.02, mutatis mutandis), no supplemental indenture may without the consent of the Holders of each outstanding Debenture directly affected thereby: (i) modify the Put Right of Holders of the Debentures
upon a Failed Remarketing in a manner materially adverse to the rights of the Holders, (ii) modify the Remarketing provisions of the Debentures in a manner materially adverse to the rights of the Holders or (iii) modify
Section 2.15 hereof in a manner materially adverse to the rights of the Holders, it being understood that any modification of the terms of the Debentures permitted pursuant to Section 9.04 in

ARTICLE IX 
 REMARKETING

 Section 9.01 Remarketing Procedures. 

(a) In the case of an Optional Remarketing, unless a Termination Event has occurred prior to the Optional Remarketing Period, or in the case
of a Final Remarketing, unless a Successful Optional Remarketing or Termination Event has occurred prior to the Final Remarketing Period, the Company shall engage the Remarketing Agent(s) pursuant to the Remarketing Agreement for the Remarketing of
the Debentures as set forth under Section 9.02. The Company shall, no later than (a) in the case of an Optional Remarketing, five Business Days prior to the first day of the Optional Remarketing Period or (b) in
the case of a Final Remarketing, seven days prior to the first day of the Final Remarketing Period, request that the Depository or its nominee notify the Beneficial Owners or Depository Participants holding Separate Debentures, Corporate Units and
Treasury Units, and shall provide a copy of such request to the Collateral Agent and the Purchase Contract Agent, in the case of an Optional Remarketing, of the Company’s intent to attempt an Optional Remarketing in the Applicable Remarketing
Period, and in all cases, of the proposed Remarketing Dates and the procedures to be followed in each Remarketing, including the procedures to be followed by Holders of Separate Debentures to participate in a Remarketing, the applicable procedures
for Holders of Corporate Units to create Treasury Units or Holders of Treasury Units to recreate Corporate Units, as the case may be, the applicable procedures for Holders of Corporate Units to effect an Early Settlement and, in the case of a Final
Remarketing, applicable procedures to effect a Cash Settlement and the applicable procedures that 

  
 11 

 
must be followed by a Holder of Separate Debentures if such Holder wishes to exercise its Put Right or by a Holder of Corporate Units if such Holder elects not to exercise its Put Right. 

(b) At any time after notice is given by the Company in accordance with Section 9.01(a), other than during a
Blackout Period, each Holder of Separate Debentures may elect to have Separate Debentures held by such Holder remarketed in the applicable Remarketing for which notice was given. A Holder making such an election must notify the Custodial Agent and
deliver such Separate Debentures to the Custodial Agent in accordance with the provisions set forth in the Purchase Contract and Pledge Agreement. Any such notice and delivery may not be conditioned upon the level at which the Reset Rate is
established in the Remarketing. Any such notice and delivery may be withdrawn, other than during a Blackout Period, by notifying the Custodial Agent on or 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 accordance with the Purchase Contract and Pledge Agreement. Any such notice and delivery not withdrawn in accordance with the immediately preceding sentence will be irrevocable with respect to each
Remarketing to occur during the Applicable Remarketing Period. Pursuant to Section 5.02 of the Purchase Contract and Pledge Agreement, by 4:00 p.m., New York City time on the Business Day immediately preceding the first day of the Applicable
Remarketing Period, the Custodial Agent, based on the notices and deliveries received by it prior to such time, shall notify the Remarketing Agent of the aggregate principal amount of Separate Debentures surrendered for Remarketing. Pursuant and
subject to Section 5.02 of the Purchase Contract and Pledge Agreement, Debentures that underlie Applicable Ownership Interests in Debentures included in Corporate Units will be deemed surrendered for Remarketing (unless in the case of a final
Remarketing, the Holder thereof has duly notified the Purchase Contract Agent of its intent to effect a Cash Settlement and timely paid the Purchase Price) and will be remarketed in accordance with the terms of the Remarketing Agreement and the
Purchase Contract and Pledge Agreement. 
 (c) The right of each Holder of Remarketed Debentures to have such Debentures remarketed on any
Remarketing Date and sold on any Optional Remarketing Date or Final Remarketing Date, as the case may be, shall be subject to the conditions that (i)(A) the Remarketing Agent conducts any Optional Remarketing or (i)(B) in the case of a Final
Remarketing, that no Successful Optional Remarketing has occurred pursuant to the terms of the Remarketing Agreement and the Purchase Contract and Pledge 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) are able to find a purchaser or purchasers for Remarketed Debentures at the Remarketing Price based on the Reset Rate and (iv) each condition precedent to
settlement of the Remarketed Debentures set forth in the Remarketing Agreement is satisfied or waived. 
 (d) Neither the Trustee, the
Company, nor the Remarketing Agent(s) shall be obligated in any case to provide funds to make payment upon surrender of Debentures for remarketing. 

Section 9.02 Remarketing. 

(a) Unless a Termination Event has occurred prior to such date, if the Company elects to conduct an Optional Remarketing during an Optional
Remarketing Period selected by the Company pursuant to the Purchase Contract and Pledge Agreement, the Remarketing Agent shall use its commercially reasonable efforts to remarket the Remarketed Debentures at the applicable Remarketing Price as
provided in the Remarketing Agreement. 
 (b) In the case there is no Successful Optional Remarketing during the Optional Remarketing
Period, either because the Remarketing Agent is unable to remarket the Debentures at the applicable Remarketing Price or because a condition precedent to the Remarketing has not been satisfied, 

  
 12 

 
and unless a Termination Event has occurred prior to such date, during the Final Remarketing Period, the Remarketing Agent shall use its commercially reasonable efforts to remarket the Remarketed
Debentures at the applicable Remarketing Price as provided in the Remarketing Agreement. The Remarketing on any Remarketing Date will be considered successful if the resulting proceeds are at least equal to the applicable Remarketing Price. The
Company has the right to postpone any Optional Remarketing for any reason in its sole and absolute discretion. The Company has the right to postpone the Final Remarketing in its sole and absolute discretion on any day prior to the last three
Business Days of the Final Remarketing Period. 
 Section 9.03 Reset Rate. 

(a) In connection with each Remarketing, in order to remarket the Debentures, the Remarketing Agent, in consultation with the Company, may
reset the interest rate on the Debentures either upward or downward, or if any Debentures are remarketed as floating-rate notes, may determine the index selected by the Company and the reset spread applicable to such Debentures (the new interest
rate in the case of fixed-rate Debentures, and the index plus the reset spread, in the case of floating-rate notes, referred to as the “Reset Rate”), as provided in the Remarketing Agreement. 

(b) Anything herein to the contrary notwithstanding, no Reset Rate shall in any event exceed the maximum rate permitted by applicable law.

 (c) In the event of a Successful Remarketing, the interest rate for the Debentures may be reset on the Remarketing Settlement Date to the
applicable Reset Rate as determined by the Remarketing Agent, in consultation with the Company, under the Remarketing Agreement, and the Company shall (1) notify the Trustee by an Officer’s Certificate delivered to the Trustee and
(2) request the Depository to notify its Depository Participants holding Debentures, in each case, of the maturity date, the Reset Rate, the Interest Payment Dates and any other modified terms established for the Debentures during the
Remarketing no later than 9:00 a.m. New York time on the Business Day following the date of such Successful Remarketing. Upon a Successful Remarketing, if the interest rate for the Debentures is reset, the Reset Rate shall apply to all outstanding
Debentures, whether or not the Holders of all outstanding Debentures participated in such Remarketing. 
 (d) If a reset of the interest
rate on the Debentures occurs pursuant to a Successful Optional Remarketing, the Reset Rate of the Debentures shall be the interest rate or reset spread determined by the Remarketing Agent(s), in consultation with the Company, pursuant to the
Remarketing Agreement, as the interest rate or reset spread the Debentures should bear in order for the Remarketing proceeds to equal at least 100% of the sum of the Treasury Portfolio Purchase Price and the Separate Debentures Purchase Price (if
any). 
 (e) If a reset of the interest rate on the Debentures occurs pursuant to a Successful Final Remarketing, the Reset Rate shall be
the interest rate determined by the Remarketing Agent(s), in consultation with the Company, pursuant to the Remarketing Agreement, as the rate the Debentures should bear in order for the Remarketing proceeds to equal at least 100% of the aggregate
principal amount of Debentures to be remarketed. 
 (f) In the event of a Failed Final Remarketing, or if no Applicable Ownership Interests
in Debentures are included in Corporate Units (or the Holder of each such Corporate Unit has duly notified the Purchase Contract Agent of its intent to effect a Cash Settlement and timely paid the Purchase Price) and none of the Holders of the
Separate Debentures elect to have their Debentures remarketed in any Remarketing, the applicable interest rate on the Debentures will not be reset and will continue to be the Coupon Rate. 

  
 13 

 (g) If there is a Failed Remarketing, the Company shall cause a notice of the unsuccessful
Remarketing to be published not later than 9:00 a.m., New York City time on the Business Day following the Applicable 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. 
 Section 9.04 Modification of Terms in Connection with a Successful
Remarketing. 
 (a) In consultation with the Remarketing Agent and without the consent of any Holders of the Debentures, the Company may
(but will not be required to) elect to, pursuant to Section 9.03, remarket any Debentures as fixed-rate notes or floating-rate notes and, in the case of floating-rate notes, provide that the interest rate on the Debentures
shall be equal to an index selected by the Company plus the reset spread (as determined by the Remarketing Agent), in consultation with the Company, in which case interest on the Debentures may be calculated on the basis of a 360 day year and the
actual number of days elapsed (or such other basis as is customarily used for floating-rate Debentures bearing interest at a rate based on such index rate). 

(b) The modifications listed in Section 9.04(a) shall take effect only if the Remarketing is successful. All such
modifications, without the consent of the Holders, shall be effective upon the earlier of the applicable Remarketing Settlement Date and the Purchase Contract Settlement Date and shall apply to all of the Debentures, regardless of whether the
Debentures were included in the Remarketing; provided, however, that if the Company makes any such elections in connection with an Optional Remarketing and no Successful Remarketing occurs during the Optional Remarketing Period, such
elections shall cease to apply and the Company may make new elections in connection with the Final Remarketing. 
 Section 9.05 Put
Right. 
 (a) If there has not been a Successful Remarketing on or prior to the last day of the Final Remarketing Period, Holders of
Debentures will, subject to this Section 9.05, have the right (the “Put Right”) to require the Company to purchase such Debentures for cash on the Purchase Contract Settlement Date, at a price per Debenture
to be purchased equal to the principal amount of the applicable Debenture (the “Put Price”). 
 (b) The Put Right of a
Holder of a Separate Debenture shall only be exercisable upon delivery of a notice substantially in the form attached as Exhibit B hereto (or, in the case of Global Debentures, in accordance with applicable procedures of the Depository), together
with such Holder’s Separate Debentures, to the Trustee by such Holder at or prior to 4:00 p.m., New York City time, on the second Business Day immediately preceding the Purchase Contract Settlement Date. Such Put Right for a Holder of a
Separate Debenture may be exercised with respect to all or a portion of such Holder’s Separate Debentures (so long as such portion is an integral multiple of $1,000 principal amount). Prior to the Purchase Contract Settlement Date, the Company
shall deposit with the Trustee immediately available funds in an amount sufficient to pay, on the Purchase Contract Settlement Date, the aggregate Put Price of all Separate Debentures with respect to which a Holder has exercised a Put Right. In
exchange for any Separate Debentures surrendered pursuant to the Put Right, the Trustee shall then distribute such amount to the Holders of such Separate Debentures. 

(c) If there has not been a Successful Remarketing on or prior to the last day of the Final Remarketing Period, the Put Right of Holders with
respect to Debentures relating to Applicable Ownership Interests in Debentures included in Corporate Units will be deemed to be automatically exercised in accordance with Section 5.02(b) of the Purchase Contract and Pledge Agreement (unless any

  
 14 

 
such Holder has duly notified the Purchase Contract Agent of its intent to effect a Cash Settlement and timely paid the Purchase Price). 

(d) Debentures purchased pursuant to the Put Right shall be cancelled by the Trustee.

each Holder (or Beneficial Owner) will be deemed to have agreed for U.S. federal, state and local income tax purposes (unless otherwise required by any taxing authority) (a) 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 Debentures underlying the Applicable Ownership Interest in Debentures constituting a part of such Corporate Unit, (b) to treat
the Debentures as indebtedness that are contingent payment debt instruments (as that term is used in U.S. Treasury Regulations Section 1.1275-4), (c) to be bound by the Company’s determination of the
comparable yield and projected payment schedule with respect to the Debentures, (d) with respect to Holders who purchase Corporate Units upon issuance, to allocate, as of the Original Issue Date, 100.0% of a Holder’s purchase price for a
Corporate Unit to the Applicable Ownership Interests in Debentures and 0.0% to each Purchase Contract, which will establish each Holder’s initial tax basis in each Purchase Contract as $0.00 and each Holder’s initial tax basis in each
Applicable Ownership Interest in Debentures as $50.00, and (e) 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. 

Section 11.02 FATCA. The Company agrees (i) to provide the Purchase Contract Agent and the Collateral Agent with such
reasonable information as it has in its possession to enable the Contract Agent and the Collateral Agent to determine whether any payments pursuant to the Indenture are subject to the withholding requirements described in Section 1471(b) of the
US Internal Revenue Code of 1986 (the “Code”) or otherwise imposed pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof (“Applicable
Law”), and (ii) that the Contract Agent and the Collateral Agent shall be entitled to make any withholding or deduction from payments under the Indenture to the extent necessary to comply with Applicable Law, for which the Contract
Agent and the Collateral Agent shall not have any liability.

have received an incumbency certificate listing persons designated to give such instructions or directions 

  
 17 

 
and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the
Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s
understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions
notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee,
including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any Note
provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary (or its

to any suit, action or proceeding that may be brought in connection with this Indenture or any Security, including such actions, suits or proceedings relation to securities laws of the United States of America or any state thereof, in such courts
whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an inconvenient forum.”

 AMERICAN ELECTRIC POWER COMPANY, INC., a corporation duly organized and existing under the laws of the state of New York
(herein referred to as the “Company,” which term includes any successor person under the Indenture hereinafter referred to), for value received, hereby promises to pay to the Registered Holder named above, the principal sum [of [•]
Dollars]*** [specified in the Schedule of Increases or Decreases in Debentures annexed hereto]* on August 15, 2025 (the “Stated
Maturity”), and to pay (subject to deferral as set forth herein) interest thereon at the rate of 1.30% per annum, such interest to accrue from August 14, 2020, subject to any reset of such interest rate in connection with a
Successful Remarketing, as described below. Subject to the Company’s right to defer interest payments as set forth in Supplemental Indenture No. 2 (as defined on the reverse hereof) and to changes in the interest payment dates as set forth
in Supplemental Indenture No. 2 in connection with a Successful Remarketing, interest is payable quarterly in arrears on each February 15, May 15, August 15 and November 15, commencing on November 15, 2020 (the
“Interest Payment Dates”), until the principal thereof is paid or made available for payment. On and after the Purchase Contract Settlement Date or, if earlier, the Optional Remarketing Settlement Date, interest on this Debenture
will be payable at the relevant Reset Rate or, if the interest rate has not been reset, at the Coupon Rate of 1.30% per year. The Reset Rate, if any, shall be established pursuant to the terms of the Indenture and the Remarketing Agreement. If
Interest Payments are deferred or otherwise not paid, they will accrue and compound on each Interest Payment Date until paid at the annual rate of 1.30% per annum, to the extent permitted by applicable law. 

The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months, and with respect to any period less than a full calendar month, on the basis of the actual number of days elapsed during the period. The interest so payable on an Interest Payment Date will be paid to
the Person in whose name this Debenture is registered, at the close of business on the Regular Record Date next preceding such Interest Payment Date; provided that interest payable at Stated Maturity will be paid to the Person to whom
principal is payable. Any such interest that is not so punctually paid or duly provided for, and that is not deferred as described below, will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid (i) to
the Person in whose name this Debenture (or any Debenture issued upon registration of transfer or exchange thereof) is registered at the close of business on the record date for the payment of such defaulted interest established in accordance with
Section 307 of the Base Indenture or (ii) at any time in any other lawful manner not inconsistent with the requirements of the securities exchange, if any, on which the Debenture may be listed, and upon such notice as may be required by
such exchange. The “Regular Record Date” with respect to any Interest Payment Date for the Debentures, will be the thirtieth day of the calendar month immediately preceding the calendar month in which the applicable Interest Payment

 If an Interest Payment
Date or the Stated Maturity of the Debentures or the date (if any) on which the Company is required to purchase the Debentures falls on a day that is not a Business Day, the applicable payment will be made on the next succeeding Business Day, and no
interest shall accrue or be paid in respect of such delay. 
 This Debenture may be presented for payment of principal and interest at the office of the
Paying Agent, in the Borough of Manhattan, City and State of New York; provided, however, that at the option of the Company, interest on this Debenture may be paid by check mailed to the address of the Person entitled thereto, as the
address shall appear on the Security Register, or by a wire transfer to an account designated by the Person entitled thereto. Payment of the principal and interest on this Debenture shall be made in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and private debts. 
 The indebtedness of the Company evidenced by this Debenture,
including the principal hereof and interest hereon, is, to the extent and in the manner set forth in the Indenture, subordinate and junior in right of payment to the Company’s obligations to Holders of Senior Indebtedness of the Company and
each Holder of this Debenture, by acceptance hereof, agrees to and shall be bound by such provisions of the Indenture and all other provisions of the Indenture. 

Reference is hereby made to the further provisions of this Debenture set forth on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place. 
 In the event of any inconsistency between the provisions of this Debenture and the provisions of the
Indenture, the provisions of the Indenture shall govern and control. 
 This Debenture shall not be entitled to any benefit under the Indenture, or be valid
or become obligatory for any purpose until the certificate of authentication hereon shall have been manually or electronically signed by an authorized signatory of the Trustee under the Indenture.

 REVERSE OF DEBENTURE 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to
be issued pursuant to the Junior Subordinated Indenture (the “Base Indenture”), dated as of March 1, 2008, between the Company and The Bank of New York Mellon Trust Company, N.A., as supplemented and amended by Supplemental
Indenture No. 2 dated as of August 14, 2020 by and between the Company and the Trustee (“Supplemental Indenture No. 2”, and together with the Base Indenture, as it may be hereafter supplemented or
amended from time to time, the “Indenture”). Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders
(the word “Holder” or “Holders” meaning the registered holder or registered holders) of the Debentures. This Security is one of the series designated on the face hereof (the “Debentures”) which is
limited in aggregate principal amount to $850,000,000. 
 Capitalized terms used herein but not defined herein shall have the respective
meanings assigned thereto in the Indenture. 
 The Debentures shall be remarketed as provided in Supplemental Indenture No. 2. In
connection with a Successful Remarketing, the Remarketing Agent, in consultation with the Company, may remarket the Debentures as fixed- or floating-rate Debentures and reset the interest rate of the Debentures. Furthermore, in connection with a
Successful Remarketing, the Company will cease to have the ability to defer interest payments on the Debentures. Following any Successful Remarketing of the Debentures, if the Debentures are remarketed as fixed-rate notes, interest on the Debentures
will be payable semi-annually on February 15 and August 15 of each year or, if the Debentures are remarketed as floating-rate notes, interest on the Debentures will be payable quarterly in arrears on February 15, May 15,
August 15 and November 15 of each year. 
 Pursuant to Supplemental Indenture No. 2, if there has not been a Successful
Remarketing prior to the end of the Final Remarketing Period, Holders of the Debentures will have the right to require the Company to purchase such Debentures for cash on the Purchase Contract Settlement Date at a price per Debenture to be purchased
equal to the principal amount of the applicable Debenture. 
 The Debentures are not subject to the operation of any sinking fund and,
except as set forth in Supplemental Indenture No. 2, are not repayable at the option of a Holder thereof prior to the Stated Maturity. 

In the case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Debentures
may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 

Prior to the Purchase Contract Settlement Date, the provisions of Section 701 of the Base Indenture shall not apply to the Debentures.

 The Company will not pay any additional amounts to any Holder in respect of any tax, assessment or governmental charge. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Debentures by the Company and the Trustee with the consent of the Holders of not less than a majority in 

  
 A-6 

 
principal amount of the Debentures outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Debentures at the time
outstanding, on behalf of the Holders of all outstanding Debentures, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount in certain
instances of the outstanding Debentures, to waive on behalf of all of the Holders of Debentures, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Debenture shall be conclusive and
binding upon such Holder and upon all future Holders of this Debenture and of any Debenture issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this
Debenture. 
 As provided in and subject to the provisions of the Indenture, no Holder of Debentures shall have any right by virtue or by
availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless such
holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as provided in the Indenture, and unless also the Holders of not less than a majority in principal amount of all the Securities
at the time outstanding (considered as one class) shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee under the Indenture and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute
any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 812 of the Base Indenture; it being understood and intended, and being expressly covenanted by
the taker and Holder of every Debenture with every other taker and Holder and the Trustee, that no one or more Holders of Debentures shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect,
disturb or prejudice the rights of the Holders of any other of such Securities, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the Indenture, except in the manner therein provided
and for the equal, ratable and common benefit of all Holders of Securities. For the protection and enforcement of the provisions of Section 807 of the Base Indenture, each and every Holder and the Trustee shall be entitled to such relief as can
be given either at law or in equity. 
 Nothing contained in the Indenture is intended to or shall impair, as between the Company and the
Holders of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay to such Holders the principal of and interest on such Debentures when, where and as the same shall become due and payable, all in accordance with
the terms of the Debentures, or is intended to or shall affect the relative rights of such Holders and creditors of the Company other than the holders of the Senior Indebtedness of the Company, nor shall anything herein or therein prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under the Indenture, subject to the rights, if any, under Article XIV of the Base Indenture of the holders of Senior Indebtedness
of the Company in respect of cash, property, or securities of the Company received upon the exercise of any such remedy. 
 As provided in
the Indenture and subject to certain limitations therein set forth, the transfer of this Debenture may be registered on the Security Register upon surrender of this Debenture for registration of transfer at the offices maintained by the Company or
its agent for such purpose, duly endorsed by the Holder hereof or his attorney duly authorized in writing, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Securities registrar duly executed by the
Holder hereof or his attorney duly authorized in writing, but without payment of any charge other than a sum sufficient to reimburse the Company for any tax or other governmental charge incident thereto. Upon any such registration of transfer, a new
Debenture or Debentures of authorized denomination or denominations for the same aggregate principal amount will be issued to the transferee in exchange herefor. 

  
 A-7 

 No service charge shall be made for any registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 

Pursuant to Supplemental Indenture No. 2, Debentures corresponding to Applicable Ownership Interests in Debentures that are no longer a
component of the Corporate Units and are released from the Collateral Account will be initially issued as Global Debentures. Except upon recreation of Corporate Units and except as otherwise provided in the Indenture, Debentures represented by
Global Debentures will not be exchangeable for, and will not otherwise be issuable as, Debentures in certificated form. Unless and until such Global Debentures are exchanged for Debentures in certificated form, Global Debentures may be transferred,
in whole but not in part, and any payments on the Debentures shall be made, only to the Depository or a nominee of the Depository, or to a successor Depository selected or approved by the Company or to a nominee of such successor Depository. 

By acceptance of this Debenture or a beneficial interest in this Debenture, each Holder hereof and any Person acquiring a beneficial interest
herein, for United States federal, state and local tax purposes, agrees to treat this Debenture as indebtedness that is a contingent payment debt instrument and to take other positions for such tax purposes as set forth in Supplemental Indenture
No. 2. 
 Prior to due presentment for registration of transfer of this Debenture, the Company, the Trustee, and any agent of the
Company or the Trustee may deem and treat the person in whose name this Debenture shall be registered upon the Security Register of this series as the absolute owner of this Debenture (whether or not this Debenture shall be overdue and
notwithstanding any notation of ownership or other writing hereon) for the purpose of receiving payment of or on account of the principal hereof and, subject to the provisions on the face hereof, interest due hereon and for all other purposes; and
neither the Company nor the Trustee nor any such agent shall be affected by any notice to the contrary. 
 No recourse shall be had for the
payment of the principal of or interest on this Debenture, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture, against any stockholder, officer, director or employee, as such, past, present or
future, of the Company or of any successor person, either directly or through the Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by
the acceptance hereof and as a part of the consideration for the issue hereof, expressly waived and released. 
 This Debenture shall be
deemed to be a contract made under the laws of the State of New York and for all purposes shall be governed by, and construed in accordance with, the laws of said State.
