 ISSUE, DESCRIPTION,
EXECUTION, REGISTRATION AND EXCHANGE OF NOTES 
 Section 2.01. Designation and Amount; Payments. The Notes are hereby created and authorized as a single series of Securities under the Original Indenture. The Notes shall be designated as the
“2.25% Convertible Senior Notes due 2019”. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is initially limited to $400,000,000, subject to Section 2.06 and except for Notes
authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 2.09, Section 2.10, Section 2.12 and Section 10.05 of the Original Indenture and Section 8.02,
Section 9.03 and Section 10.04(c) of this Supplemental Indenture. 
 The principal amount of Notes then outstanding
shall be payable on the Maturity Date. The Notes will bear interest at a rate of 2.25% per year from March 4, 2013, or from the most recent date on which interest had been paid or provided for, until the principal thereof is paid or made
available for payment. Interest is payable on each Interest Payment Date, beginning on September 1, 2013, to the Person in whose name a Note is registered on the Security Register at the close of business on the Regular Record Date immediately
preceding the applicable Interest Payment Date. If any Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date falls on a day that is not a Business Day, the required payment shall be made on the next succeeding Business
Day and no interest on such payment shall accrue in respect of such delay. 
 Section 2.02. Form of Notes. The Notes
shall be substantially in the form set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their
execution and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby. 

  
 - 12 -

 Any Global Note may be endorsed with or have incorporated in the text thereof such legends
or recitals or changes not inconsistent with the provisions of the Indenture as may be required by the Note Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and
regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to
which any particular Notes are subject. 
 Each Global Note shall represent such principal amount of the Outstanding Notes as
shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented thereby may from
time to time be increased or reduced to reflect redemptions, repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of Outstanding Notes
represented thereby shall be made on the Schedule of Exchanges of Notes to such Global Note by the Trustee or the Note Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance
with the Indenture. Payment of principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price (if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, the Global Note
shall be made to the Holder of such Note (or, in the case of consideration due upon conversion, such Holder or its designee, as the case may be) on the date of payment, unless a record date or other means of determining Holders of the Notes eligible
to receive payment is provided for herein. 
 Section 2.03. Depositary. 

(a) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be
represented by one or more Global Securities to which the provisions of Section 2.01, Section 2.09 and Section 2.15 of the Original Indenture apply (each, a “Global Note”) registered in the name of the Depositary or
the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note, shall be effected through the Depositary (but not the Trustee or the Note Custodian) in
accordance with the Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures of the Depositary therefor. 
 (b) The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company, a New York corporation (“DTC”), to act as
Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 (c) Section 2.09(d) of the Original Indenture is hereby amended and restated in full, with respect
to the Notes, to read as follows: 
 “Physical Notes shall be issued and delivered by the Company (i) to each Person
that DTC identifies as a beneficial owner of the related Securities only if (a) DTC has notified 

  
 - 13 -

 
the Company that it is unwilling or unable to continue as depositary for the Global Securities of the relevant series and a successor depositary is not appointed within 90 calendar days or
(b) DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (ii) if an Event of Default with respect to the Securities of any series has occurred and is
continuing, to each beneficial owner who requests that its beneficial interests in the Securities be exchanged for Securities in definitive form.” 
 (d) Notwithstanding anything to the contrary in the Indenture (including, without limitation, Section 1.01, Section 2.01, Section 2.09 and Section 2.15 of the Original Indenture) or
the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial owner of a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the
Depositary or any other Person, such beneficial owner’s right to exchange its beneficial interest in such Global Note for a Physical Note in accordance with Section 1.05 of the Original Indenture. 

(e) At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be,
upon receipt thereof, canceled by the Trustee in accordance with Applicable Procedures. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a
transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing
between the Depositary and the Note Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule of Exchanges of Notes to such Global Note, by the Trustee or the Note Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 Section 2.04. Cancellation of Surrendered Notes.
The Company shall cause all Notes surrendered for payment, repurchase (including pursuant to Section 2.06), redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of
the Company’s Agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation pursuant to Section 2.13 of the Original Indenture. All Notes delivered to the Trustee shall be cancelled promptly by the Trustee. No Notes
shall be authenticated in exchange for any Notes cancelled hereunder or under the Original Indenture. 
 Section 2.05.
Notice of Defaults. The Company shall deliver to the Trustee, at its Corporate Trust Office, in accordance with Section 13.02 of the Original Indenture, within 30 calendar days after the occurrence thereof, an Officers’ Certificate
containing notice of any events that would constitute Defaults, the status thereof and what action the Company is taking or proposes to take in respect thereof, which notice shall make express reference to the Company, the Indenture and the Notes.

 Section 2.06. Additional Notes; Repurchases. The Company may, without the consent of the Holders of the Notes and
notwithstanding Section 2.01, reopen this Supplemental Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued 

  
 - 14 -

 
hereunder in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax
purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such
Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 13.05 of the Original Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by
law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer
or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased to be surrendered to the Trustee for cancellation, and such Notes shall no longer be considered
Outstanding under the Indenture upon the repurchase thereof. 
 Section 2.07. Payments on Physical Notes. The
Company shall pay interest on any Physical Notes (A) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of such Notes at their address as it appears in the Security Register and (B) to
Holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each such Holder or, upon application by a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in immediately
available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies the Registrar, in writing, to the contrary.

such Event of Default is continuing. 
 If the Company so elects to pay Additional Interest, any such
Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st calendar day after such Event of Default (if the Event of Default relating to the reporting obligations is not cured
or waived prior to such 181st calendar day), the Notes
shall be subject to acceleration under Section 5.03. The provisions of this Section 5.04 shall not affect the rights of Holders of the Notes in the event of the occurrence of any other Event of Default. In the event the Company does not

Section 5.04, the Company must notify all Holders of the

is payable. 
 Section 5.05. Rescission and Annulment. Holders of a majority in principal amount of the Outstanding
Notes, by written notice to the Company and to the Trustee, may rescind any acceleration under Section 5.03 with respect to the Notes and its consequences if: 
 (a) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; 
 (b) all existing Events of Default, other than the nonpayment of the principal of and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived; and

 (c) all amounts owing to the Trustee hereunder have been paid. 

No such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right
consequent thereon.

the Fundamental Change Repurchase Price, principal and interest that are not made when due shall accrue interest per annum at the then-applicable interest rate plus one percent from the required payment date.

the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal, including the Fundamental Change Repurchase Price, if
applicable, the Redemption Price, if applicable, or interest, as the case may be, with interest upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of accrued
and unpaid interest determined in accordance with the first paragraph of this Section 5.06 and (ii) any amounts due the Trustee under Section 7.06 of the Original Indenture. 

In case the Company shall fail forthwith to pay such amounts, upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any
such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be
payable.

obligor on the Notes under any Bankruptcy Law, or any other

Company, the property of the Company, or in the case of any other judicial proceedings relative to the Company upon the Notes, or to the creditors or property of the Company, the Trustee, irrespective of whether the principal of the Notes shall then
be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.06, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal (including the Fundamental Change Repurchase Price, if applicable), the Redemption Price, if applicable, and accrued and unpaid interest in respect of
the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Holders of the Notes allowed in such judicial
proceedings relative to the Company on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of
any amounts due the Trustee under Section 7.06 of the Original Indenture, and to take any other action with respect to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or
advisable, unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders of the Notes to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of the Notes, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements,
including counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for
any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the Holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of the Notes any plan of reorganization, arrangement, adjustment or composition affecting the Holder or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of the Notes in any such proceeding. 
 All rights of action
and of asserting claims under the Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or
proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 
 In any proceedings brought by the
Trustee (and in any proceedings involving the interpretation of any provision of the Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any
Holders of the Notes parties to any such proceedings. 

  
 - 20 -

 In case the Trustee shall have proceeded to enforce any right under the Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders of the
Notes, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders of the Notes, and the Trustee
shall continue as though no such proceeding had been instituted. 
 Section 5.07. Application of Monies Collected by
Trustee. Any monies collected by the Trustee pursuant to this Article V with respect to the Notes and any other monies or property distributable in respect of the Company’s obligations under this Indenture following an Event of Default
specified in Section 5.02(i) or Section 5.02(j) with respect to the Company shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid (or in accordance with Applicable Procedures, with respect to Global Notes): 
 First, to the payment of all amounts due the Trustee and any predecessor Trustee under Section 7.06 of the Original Indenture; 

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

Third, in case the principal of the Outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the
payment of the whole amount (including the Redemption Price or Fundamental Change Repurchase Price and any cash due upon conversion, if applicable) then owing and unpaid upon the Notes for principal and interest, if any, and any cash due upon
conversion other amounts then payable on the Notes, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of accrued and unpaid interest and any such cash due upon
conversion or other amounts at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and such
interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such
principal and such accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company.

 Section 5.08. Proceedings by Holders of the Notes. No Holder of any Note shall
have any right by virtue of 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, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, except to enforce the right to receive payment of principal or interest on the Notes when due or the right to receive payment or delivery of the consideration due upon
conversion of the Notes, unless: 
 (a) such Holder shall have given to the Trustee written notice of an Event of Default and of
the continuance thereof; 
 (b) such Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall
have made written request upon the Trustee to institute such action, suit or proceeding; 
 (c) such Holders shall have offered
to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; 
 (d) the
Trustee shall not have complied with such request within 60 calendar days after the receipt of the request and the offer of security or indemnity; and 
 (e) the Holders of a majority in aggregate principal amount of the Outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within
such 60-day period pursuant to Section 5.11; 
 it being understood and intended, and being expressly covenanted by the taker and Holder of
every Note with every other taker and Holder of the Notes and the Trustee that no one or more Holders of the Notes shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or
prejudice the rights of any other Holder of the Notes, or to obtain or seek to obtain priority over or preference to any other such Holder of the Notes, or to enforce any right under the Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all Holders of the Notes (except as otherwise provided herein). For the protection and enforcement of this Section 5.08, each and every Holder of the Notes and the Trustee shall be entitled to such relief as
can be given either at law or in equity. 
 Notwithstanding any other provision of the Indenture and any provision of the Notes,
the right of the Holder of any Note to receive payment or delivery, as the case may be, of (w) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (x) accrued and unpaid interest, if any, on, (y) if
applicable, the Redemption Price of and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any
such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. 
 Anything contained in this Indenture or the Notes to the contrary notwithstanding, the Holder of any Note, without the consent of either the Trustee or the Holder of any other Note, in its own behalf and
for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 

  
 - 22 -

 Section 5.09. Proceedings by Trustee. In case of an Event of Default, the
Trustee may, in its discretion, proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law
or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable
right vested in the Trustee by the Indenture or by law. 
 Section 5.10. Remedies Cumulative and Continuing. All
powers and remedies given by this Article V to the Trustee or to the Holders of the Notes shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or
the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to
exercise any right or power accruing upon any Default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence
therein; and, subject to the provisions of Section 5.08, every power and remedy given by this Article V or by law to the Trustee or to the Holders of the Notes may be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Holders of the Notes. 
 Section 5.11. Direction of Proceedings and Waiver of Defaults by Majority
of Holders of the Notes. The Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available
to the Trustee or of exercising any trust or power conferred on the Trustee with respect to Notes; provided, that (i) such direction shall not be in conflict with any rule of law or with the Indenture, and (ii) the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder of the Notes or that would involve
the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may, on behalf of the Holders of all of the Notes, waive any past Default or Event of Default hereunder and its
consequences except (i) a default in the payment of principal of, or interest on, any Note when due, and (ii) a failure by the Company to fulfill its Conversion Obligation and convert any Notes in accordance with the provisions of the
Indenture. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair
any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.11, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have
been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

  
 - 23 -

 Section 5.12. Notice of Defaults. If a Default has occurred and is continuing
and is known to the Trustee, the Trustee shall mail to each Holder of the Notes, at the address of such Holder included in the Security Register, notice of such Default within 90 calendar days after it occurs; provided that, except in the
case of a Default in the payment of the principal of, or interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a
committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of the Notes. 
 Section 6.10 of the Original Indenture shall not apply to the Notes. Instead this Section 5.12 shall, with respect to the Notes, supersede in its entirety Section 6.10 of the Original
Indenture, and all references in the Original Indenture to Section 6.10 thereof and the notice provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Section 5.12 and the notice
provisions set forth in this Section 5.12, respectively. 
 Section 5.13. Undertaking to Pay Costs. All parties
to the Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including
reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this
Section 5.13 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder of the Notes, or group of Holders of the Notes, holding in the aggregate more than 10% in principal amount
of the Notes at the time Outstanding, or to any suit instituted by any Holder of the Notes for the enforcement of the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price, if
applicable, of, or accrued and unpaid interest, if any, on, any Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article
VIII.

thereby. 

  
 - 25 -

 The portion of the second sentence of Section 10.02 of the Original Indenture preceding
clause (a) thereof is hereby amended and restated, with respect to the Notes, to read as follows:

 ARTICLE VII 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

 Section 7.01. Applicability of Article 5 of the Original Indenture. Article 5 of the Original Indenture shall not
apply to the Notes. The provisions set forth in this Article VII shall, with respect to the Notes, supersede in their entirety Article 5 of the Original Indenture, and all references in the Original Indenture to Article 5 thereof shall, with respect
to the Notes, be deemed to be references to this Article VII. 
 Section 7.02. Company May Consolidate, etc. on Certain
Terms. Subject to the provisions of Section 7.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its assets to, another Person (any such transaction, a
“Consolidation Transaction”), unless: 
 (a) the resulting, surviving or transferee Person (the
“Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company)
shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and the Indenture; and 

(b) immediately after giving effect to the transaction, no Default or Event of Default shall have occurred and be continuing. 

For purposes of this Section 7.02, the sale, conveyance, transfer or lease of all or substantially all of the assets of one or more

conveyance, transfer or lease of all or substantially all of the assets of the Company to another Person. 

  
 - 26 -

 Section 7.03. Successor Company to be Substituted. Upon any such consolidation,
merger or sale, conveyance, transfer or lease, the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor had been named as the
Company herein; and thereafter the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of any such lease.

appropriate. 
 Section 7.04. Opinion of Counsel to be Given to Trustee. The Company shall not enter into any
consolidation, merger, sale, conveyance, transfer or lease subject to Section 7.02 unless the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale,
conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article VII. 

ARTICLE VIII 

CONVERSION OF NOTES 
 Section 8.01. Conversion Privilege. Article 12 of the Original Indenture shall not apply to the Notes. 
 (a) Subject to and upon compliance with the provisions of this Article VIII, each Holder of the Notes shall have the right, at such Holder’s option, to irrevocably convert all or any portion (if the
portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 8.01(b), at any time prior to the close of business on the Business Day
immediately preceding December 1, 2018 under the circumstances and during the periods set forth in Section 8.01(b), and (ii) irrespective of the conditions described in Section 8.01(b), on or after December 1, 2018 until the
close of business on the second Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 94.3396 shares of Common Stock (subject to adjustment as provided in Section 8.04, the “Conversion
Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 8.02, the “Conversion Obligation”). 
 (b) (i) Prior to the close of business on the Business Day immediately preceding December 1, 2018, the Notes may be surrendered for conversion during the five Business Day period immediately after
any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of the Notes in accordance with this subsection (b)(i)
and the definition of “Trading Price” in Section 1.02, for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading
Day (the “Trading Price Condition”). 
 (A) The Trading Price shall be determined by the
Company based on bids, if any, received by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture. 

  
 - 27 -

 (B) The Bid Solicitation Agent shall have no obligation to determine the
Trading Price per $1,000 principal amount of Notes or whether the Trading Price Condition has been met. The Bid Solicitation Agent shall have no obligation to solicit bids from nationally recognized securities dealers the Company selects unless the
Company has requested such solicitation in writing providing the name and contact information for the nationally recognized securities dealers the Company has chosen and the determination dates for which such market bid quotations are to be
solicited, and the Company shall have no obligation to make such request or determine the Trading Price unless a Holder of the Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent to solicit bids pursuant to this subsection (b)(i) and the definition of
Trading Price, and based upon such bids the Company shall determine the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of
Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. 
 (C) If (x) the Company does not, when it is required to, instruct the Bid Solicitation Agent to solicit bids as described above, (y) the Company gives such instruction to the Bid Solicitation
Agent to solicit bids and the Bid Solicitation Agent fails to obtain such bids or (z) the Bid Solicitation Agent obtains such bids and the Company fails to determine the Trading Price based upon such bids, then, in each case, the Trading Price
per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. 

(D) If the Trading Price Condition has been met on any Trading Day, the Company shall provide notice thereof to the
Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing on such Trading Day, subject to Section 13.02 of the Original Indenture. If, at any time after the Trading Price Condition has been met, the
Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such Trading Day, the Company shall promptly provide notice thereof to
the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing, subject to Section 13.02 of the Original Indenture. 

  
 - 28 -

 (ii) If, prior to the close of business on the Business Day immediately
preceding December 1, 2018, the Company elects to: 
 (A) issue to all or substantially all holders of its
Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(B) distribute to all or substantially all holders of its Common Stock the Company’s assets, debt securities or
rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the shares of Common Stock on the Trading Day preceding the
date of announcement for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the
Conversion Agent (if other than the Trustee) at least 20 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time
until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place,
even if the Notes are not otherwise convertible at such time. 
 Holders of the Notes may not exercise this conversion right if each Holder has
the right to participate (as a result of holding the Notes, and at the same time and on the same terms as Holders of shares of Common Stock participate) in any of the transactions described above as if such Holder of the Notes held a number of
shares of Common Stock equal to (i) the applicable conversion rate, multiplied by (ii) (x) the principal amount of Notes held by such Holder divided by (y) $1,000, without having to convert its notes. 

(iii) If a transaction or an event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior
to the close of business on the Business Day immediately preceding December 1, 2018, regardless of whether a Holder of the Notes has the right to require the Company to repurchase the Notes pursuant to Section 9.01, or if the Company is a
party to a consolidation, merger, binding share exchange or similar transaction, or transfer or lease of all or substantially all of its assets, pursuant to which the Common Stock would be converted into cash, securities or other assets, the Notes
may be surrendered for conversion at any time from or after the date that is 20 Scheduled Trading Days prior to the anticipated effective date of such transaction or event (or, if later, the Business Day after the Company gives notice of such
transaction or event) up to, and including, the date that is 35 Trading Days after the actual effective date of such transaction or event, or, if such transaction or event also constitutes a Fundamental Change, up to, and including, the related
Fundamental Change Repurchase 

  
 - 29 -

 
Date. The Company shall notify Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company publicly
announces such transaction or event, but in no event less than 20 Scheduled Trading Days prior to the anticipated effective date of such transaction or event, or (ii) if the Company does not have knowledge of such transaction or event at least
20 Scheduled Trading Days prior to the anticipated effective date of such transaction or event, within five Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction or event, but in no event
later than the actual effective date of such transaction or event. 
 (iv) Prior to the close of business on the
Business Day immediately preceding December 1, 2018, a Holder may surrender all or a portion of its Notes (that is $1,000 principal amount or an integral multiple thereof) for conversion during any calendar quarter commencing after the calendar
quarter ending on March 31, 2013 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on
the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine whether the Notes may be surrendered for conversion in accordance
with this clause (iv) and shall notify the Holders of the Notes, the Trustee and the Conversion Agent if the Notes become convertible in accordance with this clause (iv). 

(v) If, prior to the close of business on the Business Day immediately preceding December 1, 2018, the Company calls
the Notes for redemption pursuant to Article X, Holders may convert their Notes at any time prior to the close of business on the Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such time.
After that time, Holders will no longer have the right to convert their Notes on account of the Company’s delivery of the relevant Redemption Notice, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of
the Notes may convert its Notes until the Redemption Price has been paid or duly provided for. 
 Section 8.02.
Conversion Procedure; Settlement Upon Conversion. 
 (a) Subject to this Section 8.02, Section 8.03(b) and
Section 8.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder of the Notes, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash
Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 8.02(i) (“Physical Settlement”) or a combination of cash and shares of
Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 8.02(i) (“Combination Settlement”), at its election, as set forth in this Section 8.02.

 (i) All conversions occurring on or after December 1, 2018 and all conversions occurring after the
Company’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement Method. 

  
 - 30 -

 (ii) Except for any conversions that occur after the Company’s issuance
of a Redemption Notice with respect to the Notes but prior to the related Redemption Date and any conversions occurring on or after December 1, 2018, the Company shall use the same Settlement Method for all conversions occurring on the same
Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. 

(iii) Subject to the two immediately succeeding sentences, if, in respect of any Conversion Date, the Company elects a
Settlement Method in respect of such Conversion Date, the Company, through the Trustee, shall deliver the relevant Settlement Notice to converting Holders of the Notes no later than the close of business on the Trading Day immediately following the
relevant Conversion Date. In the case of any conversions occurring on or after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, if the Company elects a Settlement Method, the Company
shall notify Holders of the Notes of the relevant Settlement Method in such Redemption Notice. In the case of any conversions on or after December 1, 2018, if the Company elects a Settlement Method, the Company, through the Trustee, shall
deliver a Settlement Notice to all Holders of the Notes no later than December 1, 2018. If the Company does not elect a Settlement Method prior to the relevant deadline set forth in the three immediately preceding sentences, the Company shall
no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of
Notes shall be equal to $1,000. The Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company
elects Combination Settlement, but does not timely notify converting Holders of the Specified Dollar Amount, such Specified Dollar Amount shall be deemed to be $1,000. 

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of
Notes (the “Settlement Amount”) shall be computed by the Company as follows: 
 (A) if the
Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder a number of shares of Common Stock equal to the product of the aggregate principal amount of
Notes to be converted, divided by $1,000, and the Conversion Rate in effect on the Conversion Date; 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the
Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted, cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive Trading Days during the related
Observation Period; and 

  
 - 31 -

 (C) if the Company elects (or is deemed to have elected) to satisfy its
Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount
equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days during the relevant Observation Period. 
 (v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly
after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than
the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have
no responsibility for any such determination. 
 (b) Subject to Section 8.02(e), before any Holder of a Note shall be
entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest
Payment Date to which such Holder is not entitled as set forth in Section 8.02(g) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form
of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in
which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and
accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the
next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(g). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article VIII on the Conversion
Date for such conversion. No Holder may surrender Notes for conversion if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase
Notice in accordance with Section 9.03. 
 If more than one Note shall be surrendered for conversion at one time by the
same Holder of the Notes, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

  
 - 32 -

 (c) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the Holder of the Notes has complied with the requirements set forth in subsection (b) above. The Company shall pay or deliver, as the case may be, the consideration due (including any
cash in lieu of fractional shares) in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following
the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method (subject to the provisions of Section 8.03(b) and Section 8.07(a)). If any shares of Common Stock are due to converting Holders of the
Notes, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of
Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 
 (d) In case
any Note shall be surrendered for partial conversion, in $1,000 principal amount or an integral multiple thereof, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so
surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder of the Notes but, if required by
the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such
conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 
 (e) If a Holder of
the Notes submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares
of Common Stock to be issued in a name other than such Holder’s name, in which case such Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other
than such Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. 
 (f) Upon the conversion of an interest in a Global Note, the Trustee, or the Note Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal
amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (g) Upon conversion, a Holder of the Notes shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s payment or delivery, as the
case may be, of the Settlement Amount upon conversion of any Note shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date.
As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be 

  
 - 33 -

 
deemed to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be
deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record
Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date
to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for
conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date;
(3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (4) to the extent of any overdue Interest, if any overdue interest
exists at the time of conversion with respect to such Note. 
 (h) The Person in whose name the certificate for any shares of
Common Stock delivered upon conversion is registered shall be treated as the holder of record of such shares as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical
Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a
Holder of such Notes surrendered for conversion; provided that (a) the converting Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion between a Regular Record Date and
the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with clause (g) above.

 (i) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash
in lieu of any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation
Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the
aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. 
 Section 8.03. Adjustment to Conversion Rate upon Conversion upon a Make-Whole Fundamental Change. 
 (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder of the Notes elects to convert its Notes in connection with such Make-Whole Fundamental Change,
the Company shall, under the circumstances described 

  
 - 34 -

 
below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the
Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the
proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash
Settlement or Combination Settlement in accordance with Section 8.02; provided, however, that if, as of the Effective Date of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change,
the Reference Property is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction
and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation
shall be determined and paid to Holders of the Notes in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent in writing of the Effective Date of any
Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below in subsection 8.03(e), based on the date on which the
Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of Common Stock in the Make-Whole Fundamental Change. If the
holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise,
the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

 (d) The Stock Prices set forth in the column headings of the table below in subsection 8.03(e) shall be adjusted as of any
date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner
and at the same time as the Conversion Rate as set forth in Section 8.04. 

  
 - 35 -

 (e) The following table sets forth the number of Additional Shares to be added to the
Conversion Rate per $1,000 principal amount of Notes pursuant to this Section 8.03 for each Stock Price and Effective Date set forth below:

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

 (i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two
Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates
based on a 365-day year, as applicable; 
 (ii) if the Stock Price is greater than $75.00 per share (subject to
adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $8.00 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 125.0000, subject to adjustment in the same manner as the Conversion Rate pursuant to
Section 8.04. 
 (f) Nothing in this Section 8.03 shall prevent an adjustment to the Conversion Rate pursuant to
Section 8.04 in respect of a Make-Whole Fundamental Change. 
 Section 8.04. Adjustment of Conversion Rate. The
Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a
share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 8.04, without having to convert their
Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder of the Notes. 

  
 - 36 -

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

 

											
	CR1	 	=	 	CR0	 	×	 	 OS1
	 	
	 	 	 	 	OS0	 	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the
Effective Date of such share split or share combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and
			
	OS1	  	=	  	the number of shares of Common Stock that will be outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 8.04(a) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in
this Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors or a committee thereof determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company
issues to all or substantially all holders of its shares of Common Stock any rights, options or warrants (other than rights issued pursuant to a shareholder rights plan) entitling them, for a period of not more than 45 calendar days after the
announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and
including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	 	=	 	CR0	 	×	 	 OS0 + X
	 	
	 	 	 	 	OS0 + Y	 	

  
 - 37 -

 where, 
  

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

 Any increase made under this Section 8.04(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 For purposes of this Section 8.04(b) and Section 8.01(b)(ii)(A), in determining whether any rights, options or
warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or
warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors or a committee thereof. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company
or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment is or was effected pursuant
to Section 8.04(a) or Section 8.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment is or was effected pursuant to Section 8.04(d), and (iii) Spin-Offs as to which the provisions set
forth below in this Section 8.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the
“Distributed Property”), then the Conversion Rate shall be increased (subject in all respects to Section 8.11) based on the following formula: 

 

											
	CR1	 	=	 	CR0	 	×	 	         SP0        
	  	
	 	 	 	 	SP0 – FMV	  	

  
 - 38 -

 where, 
  

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

 Any increase made under the portion of this Section 8.04(c) above shall become
effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each
$1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to
the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors or a committee thereof determines the “FMV” (as defined above) of any distribution for purposes of this Section 8.04(c) by reference
to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing SP0. 

With respect to an adjustment pursuant to this Section 8.04(c) where there has been a payment of a dividend or other distribution on
the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S.
national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	 	=	 	CR0	 	×	 	 FMV0 + MP0
	  	
	 	 	 	 	MP0	  	

  
 - 39 -

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock
(determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.02 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period
after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph shall be determined on the last
Trading Day of the Valuation Period but shall be given effect at the open of business on the Ex-Dividend Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion during the Valuation Period, references in the portion of
this Section 8.04(c) related to Spin-Offs with respect to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including the Ex-Dividend Date of such Spin-Off to, but
excluding, the Conversion Date in determining the Conversion Rate. In addition, if the Ex-Dividend Date for the Spin-Off is less than 10 consecutive Trading Days prior to, and including, the end of the Observation Period in respect of any
conversion, references in the portion of this Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and
including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. 
 If any
such distribution that constitutes a Spin-Off is declared but not made, and such distribution has resulted in an adjustment to the Conversion Rate, the Conversion Rate shall be re-adjusted, effective as of the date the Board of Directors or a
committee thereof determines not to make such distribution, to be the Conversion Rate that would then be in effect if such distribution had not been declared. 
 For purposes of this Section 8.04(c) (and subject in all respects to Section 8.11), rights, options or warrants distributed by the Company to all holders of its shares of Common Stock entitling
them to subscribe for or purchase shares of the Company’s Capital Stock, including shares of Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events
(“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the shares of Common Stock, shall be deemed
not to have been distributed for purposes of this Section 8.04(c) (and no adjustment to the 

  
 - 40 -

 
Conversion Rate under this Section 8.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 8.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to
the date of this Supplemental Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the
occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to
terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in
the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 8.04(c) was made, (1) in the case of any such
rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had
not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or purchase price received by a holder or holders of shares 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 shares of Common Stock as of
the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights,
options and warrants had not been issued. 
 For purposes of Section 8.04(a), Section 8.04(b) and this
Section 8.04(c), if any dividend or distribution to which this Section 8.04(c) is applicable also includes one or both of: 
 (A) dividend or distribution of shares of Common Stock to which Section 8.04(a) is applicable (the “Clause A Distribution”); or 

(B) dividend or distribution of rights, options or warrants to which Section 8.04(b) is applicable (the
“Clause B Distribution”), 
 then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 8.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 8.04(c) with respect to
such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 8.04(a) and
Section 8.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date
of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be 

  
 - 41 -

 
“outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 8.04(a) or “outstanding immediately prior to
the open of business on such Ex-Dividend Date” within the meaning of Section 8.04(b). 
 (d) If any cash dividend or
distribution is made to all or substantially all holders of the shares of Common Stock (other than a regular, quarterly cash dividend that does not exceed an amount equal to $0.0025 per share (the “Initial Dividend Threshold”) and
other than dividends or distributions made in connection with the Company’s liquidation, dissolution, or winding up), the Conversion Rate shall be adjusted based on the following formula: 

 

											
	CR1	 	=	 	CR0	 	×	 	 SP0 – T
	 	
	 	 	 	 	SP0 – C	 	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such dividend or distribution;
			
	C	  	=	  	the amount of cash per share of Common Stock the Company distributes to all or substantially all holders of Common Stock; and
			
	T	  	=	  	the Initial Dividend Threshold; provided that if the dividend or distribution in question is not a regular quarterly cash dividend, the Initial Dividend Threshold will be
deemed to be zero.

 The Initial Dividend Threshold is subject to concurrent adjustment in a manner inversely proportional to
adjustments to the Conversion Rate; provided that no adjustment shall be made to the Initial Dividend Threshold for any adjustment to the Conversion Rate on account of a regular quarterly cash dividend under this clause (d). 

Any increase pursuant to this Section 8.04(d) shall become effective immediately after the open of business on
the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors or a committee thereof determines not to make or pay
such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would

  
 - 42 -

 
have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. For the avoidance of doubt,
there will not be any adjustment to the Conversion Rate under this Section 8.04(d) as a result of any distribution of Reference Property to holders of the Common Stock in connection with any Merger Event. 

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

											
	CR1	 	=	 	CR0	 	×	 	 AC + (SP1 × OS1)
	  	
	 	 	 	 	OS0 × SP1	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires (the “Expiration
Date”);
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or a committee thereof) paid or payable for shares of Common Stock purchased in
such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on the date such tender or exchange offer is consummated (prior to giving effect to the
purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the open of business on the date such tender or exchange offer is consummated (after giving effect to the purchase
of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date
such tender or exchange offer expires.

  
 - 43 -

 The adjustment to the Conversion Rate under this Section 8.04(e) shall be determined at
the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date but shall be given effect at the open of business on the Trading Day next succeeding the Expiration Date.
Notwithstanding the foregoing, in respect of any conversion within the 10 Trading Days immediately following, and including, the Trading Day next succeeding any Expiration Date, references in this Section 8.04(e) with respect to 10 Trading Days
shall be deemed replaced with such lesser number of Trading Days as have elapsed between such Expiration Date and the Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the Expiration Date is less
than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in this Section 8.04(e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such
lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading Day of such Observation Period. For the avoidance of doubt, no adjustment under this
Section 8.04(e) shall be made if such adjustment would result in a decrease in the Conversion Rate. 
 (f) Notwithstanding
anything to the contrary in this Section 8.04, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date
would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 8.02(h) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate
adjustment provisions in this Section 8.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the
shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or
the right to purchase shares of Common Stock or such convertible or exchangeable securities. 
 (h) In addition to those
adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted by applicable law and subject to the applicable rules of The New York Stock Exchange, (i) the Company may increase the
Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if the Board of Directors or a committee thereof determines that such increase would be in the Company’s best interest and (ii) the Company may (but is
not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares of Common
Stock) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice of the increase at least 15
calendar days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

  
 - 44 -

 (i) Notwithstanding anything to the contrary in Section 8.04, the Conversion Rate shall
not be adjusted: 
 (i) upon the issuance any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

(ii) upon the issuance any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any
present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 
 (iii) upon the issuance any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and
outstanding as of the date the Notes were first issued, subject to Section 8.11; 
 (iv) upon any regular,
quarterly cash dividend to holders of the Common Stock that does not exceed an amount equal to the Initial Dividend Threshold; 
 (v) solely for a change in the par value of the Common Stock; or 

(vi) for accrued and unpaid interest, if any. 
 (j) All calculations and other determinations under this Article VIII shall be made by the Company and all calculations of the Conversion Rate shall be made to the nearest one-ten thousandth
(1/10,000) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file
with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a
Responsible Officer shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder of the Notes at its last address appearing on the Security Register. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment. 
 (l) For the purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock. 

  
 - 45 -

 Section 8.05. Adjustments of Prices. Whenever any provision of the Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable, the period for
determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors or a committee thereof shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or
any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the
Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 Section 8.06. Shares to be Fully
Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares that are not reserved for other purposes or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes
from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder of the Notes and that Physical Settlement is applicable, and
including the maximum number of Additional Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change). 
 Section 8.07. Effect of Recapitalizations, Reclassifications and Changes of the Shares of Common Stock. 
 (a) In the case of: 
 (i) any recapitalization, reclassification or
change of the Common Stock (other than changes resulting from a subdivision or combination or a change solely in par value), 
 (ii) any consolidation, merger, combination or similar transaction involving the Company, 
 (iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety, or 

(iv) any statutory share exchange, 
 in each case, as a result of which the shares of Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any
such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the
kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event
would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock would have
received) upon such Merger 

  
 - 46 -

 
Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture
permitted under Section 6.01(d) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (A) the Company shall
continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of the Notes in accordance with Section 8.02 and (B) (I) any amount payable in cash upon conversion of the
Notes in accordance with Section 8.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 8.02 shall instead be
deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of
Reference Property. 
 If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive
more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (A) the weighted average of the types
and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (B) if no holders of the shares of Common Stock affirmatively make such an election, the types and amounts of consideration
actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely
cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 8.03), multiplied by the price paid per share of Common Stock in such Merger Event and
(y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other
than the Trustee) of such weighted average as soon as practicable after such determination is made. 
 Such supplemental
indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article VIII. If, in the case of any Merger Event, the
Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such
supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the
foregoing, including to the extent required by the Board of Directors and as practicable, the provisions providing for the purchase rights set forth in Article IX. Following any Merger Event, each reference herein to a share of Common Stock shall be
deemed to refer to a unit of Reference Property, subject to the provisions of such supplemental indenture. 

  
 - 47 -

 (b) In the event the Company shall execute a supplemental indenture pursuant to subsection
(a) of this Section 8.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Reference
Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders of the Notes. The Company shall cause notice of the
execution of such supplemental indenture to be mailed to each Holder of the Notes, at its address appearing on the Security Register, within 20 Business Days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. 
 (c) The Company shall not become a party to any Merger Event unless its terms are
consistent with this Section 8.07. None of the foregoing provisions shall affect the right of a Holder of the Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as
set forth in Section 8.01 and Section 8.02 prior to the effective date of such Merger Event. 
 (d) In connection with
any Merger Event, the Initial Dividend Threshold shall be subject to adjustment as described in clause (i), clause (ii) or clause (iii) below, as the case may be: 

(i) In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to
Section 8.07(a) above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “Merger Common Stock”), the Initial Dividend Threshold at and after the effective time of such
Merger Event shall be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger 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 Merger Event (such quotient rounded down to nearest cent); 
 (ii) In the case of a Merger
Event in which the Reference Property (determined, as appropriate, pursuant to Section 8.07(a) above and excluding any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the Initial Dividend Threshold at
and after the effective time of such Merger Event shall be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, multiplied by (y) the Merger Valuation Percentage for such Merger
Event (such quotient rounded down to nearest cent). 
 (iii) For the avoidance of doubt, in the case of a Merger
Event in which the Reference Property (determined, as appropriate, pursuant to Section 8.07(a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares of common stock, the Initial
Dividend Threshold at and after the effective time of such Merger Event shall be equal to zero. 
 (e) The above provisions of
this Section shall similarly apply to successive Merger Events. 

  
 - 48 -

 Section 8.08. Certain Covenants. 

(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and nonassessable by the
Company and free from all taxes, liens and charges with respect to the issue thereof. 
 (b) The Company covenants that, if any
shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the
Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c) The Company covenants that if at any time the shares of Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as
the shares of Common Stock shall be so listed on such exchange or automated quotation system, any share of Common Stock issuable upon conversion of the Notes. 
 Section 8.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder of the Notes to determine the
Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount)
of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither
the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the
purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article VIII. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 8.07 relating either to the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders of the Notes upon the conversion of their Notes after any event referred to in such Section 8.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.02 of the Original
Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with
the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 8.01(b) has occurred that
makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 8.01(b) with respect to the commencement or termination of such
conversion rights, on which notices the Trustee and the Conversion Agent 

  
 - 49 -

 
may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent promptly after the occurrence of any such event or at such other times as shall be
provided for in Section 8.01(b). 
 Section 8.10. Notice to Holders of the Notes Prior to Certain Actions. In
case of any: 
 (a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate
pursuant to Section 8.04 or Section 8.11; 
 (b) Merger Event or Consolidation Transaction; or 

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries; 

then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture, excluding for the avoidance of
doubt Section 8.04(k)), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder of the Notes at its address appearing on the Security Register, as promptly as
possible and at least 20 calendar days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record
is not to be taken, the date as of which the holders of shares of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, Consolidation
Transaction, dissolution, liquidation or winding-up is expected to become effective or occur, and, if applicable, the date as of which it is expected that holders of shares of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities or other property deliverable upon such Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such action by the Company or one of its Subsidiaries, Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up. 
 Section 8.11. Shareholder Rights Plans. If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, each share of Common Stock, if any, issued upon such
conversion shall be entitled to receive the appropriate number of rights, if any, and any certificate representing the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of
any such shareholder rights plan, as the same may be amended from time to time. If however, prior to any conversion, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights
plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of shares of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, assets,
property, rights, options or warrants to acquire its Capital Stock or other securities as provided in Section 8.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 8.12. Insurance Conversion Restriction. Notwithstanding anything to the contrary in this Indenture or the Notes, the
Notes will not be convertible by a Holder to the 

  
 - 50 -

 
extent that conversion of such Holder’s Notes would cause such Holder or a Person who directly or indirectly controls (as defined under the applicable state insurance laws and regulations),
is controlled by, or under common control with, such Holder to hold, for purposes of such insurance laws and regulations, 10% or more of the outstanding shares of Common Stock, except to the extent that the conversion of such Holder’s notes has
been approved by the applicable insurance regulator, or is exempted from the approval requirements by such regulator, under all insurance statutes and regulations applicable to the Company’s direct and indirect insurance company subsidiaries
(any such approvals or exemptions from approval requirements, the “Insurance Regulatory Approvals”) (such restriction, the “Insurance Conversion Restriction”); provided, however, that if permitted
under the applicable insurance statutes and regulations, the Insurance Conversion Restriction will not apply to the extent the Company and such Holder shall have entered into mutually agreed alternative arrangements (such as delivery of the shares
of Common Stock into which the Notes may be converted into an escrow account or voting trust) permitting the conversion of the Notes to occur pending receipt of any required Insurance Regulatory Approvals. 

Without limiting the foregoing, if any delivery of shares of Common Stock upon conversion of the Notes is not made, in whole or in part,
as a result of the Insurance Conversion Restriction, the Company’s obligation to deliver such shares of Common Stock shall not be extinguished and the Company shall deliver such shares of Common Stock as promptly as practicable following the
time at which the Insurance Conversion Restriction no longer applies and such Holder gives notice thereof to the Company. No interest will accrue and be payable on Notes under which the delivery of shares of Common Stock is not made upon conversion,
as a result of an Insurance Conversion Restriction, during any period that the delivery of shares of Common Stock upon conversion would otherwise have been made if not for the presence of such Insurance Conversion Restriction. 

In providing such notice, and in exercising its right of conversion, such Holder will be deemed to have represented to the Company that
no Insurance Conversion Restriction applies. For the avoidance of doubt, the restrictions on conversion described in the preceding paragraphs of this Section 8.12 shall apply to any exercise of a conversion right by a Holder of Notes, but in
the case of a Global Note, only to the extent that such restrictions apply to the owners of beneficial interests in such Global Note other than participants of the Depositary who hold beneficial interests in the Notes on behalf of other Persons.

 ARTICLE IX 
 REPURCHASE OF NOTES AT OPTION OF HOLDERS 

Section 9.01. Repurchase at Option of Holders of the Notes Upon a Fundamental Change 

(a) If a Fundamental Change occurs at any time, each Holder of the Notes shall have the right, at such Holder’s option, to require
the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal thereof that is equal to $1,000 principal amount or an integral multiple of $1,000 principal amount, on the date (the “Fundamental Change
Repurchase Date”) specified by the Company that is not less than 20 calendar days or more 

  
 - 51 -

 
than 35 calendar days following the date of the Fundamental Change Company Notice, subject to extension if necessary to comply with applicable securities laws, at a repurchase price equal to 100%
of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided that if the
Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, then the Company shall instead pay the full amount of accrued and unpaid interest to the
Holder of record on such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article IX. 

(b) On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the
Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the
repurchase right at the option of the Holders of the Notes arising as a result thereof. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 
 (ii) the date of
the Fundamental Change; 
 (iii) the last date on which a Holder of the Notes may exercise the repurchase right
pursuant to this Article IX; 
 (iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder of the
Notes may be converted only if such Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and 
 (ix) the procedures that the Holders of the Notes must follow to require the Company to repurchase their Notes. 
 At the Company’s request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such
Fundamental Change Company Notice shall be prepared by the Company. 

  
 - 52 -

 Such notice shall be by first class mail to the Trustee, to the Paying Agent and to each
Holder of the Notes at its address shown in the Security Register (and to beneficial owners as required by applicable law) or, in the case of Global Notes, in accordance with Applicable Procedures. Simultaneously with providing such notice, the
Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such
other public medium as the Company may use at that time. 
 No failure of the Company to give the foregoing notices and no
defect therein shall limit the repurchase rights of the Holders of the Notes or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 9.01. 

(c) Repurchases of Notes under this Section 9.01 shall be made, at the option of the Holder of the Notes thereof, upon: 

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

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the
Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of
the Depositary, in each case such delivery being a condition to receipt by the Holder of the Notes of the Fundamental Change Repurchase Price therefor. 
 (d) The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 
 (ii) the portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 

(iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the
Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with
Applicable Procedures. 
 Notwithstanding anything herein to the contrary, any Holder of the Notes delivering to the Paying
Agent the Fundamental Change Repurchase Notice contemplated by this Section 9.01 

  
 - 53 -

 
shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 9.02. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

(e) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders of the Notes upon
a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a default by the Company in the payment of
the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders of the Notes thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an
acceleration resulting from a default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary
shall be deemed to have been canceled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 9.02. Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in
whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 9.02 at any time prior to the close of business on the Business Day immediately preceding
the Fundamental Change Repurchase Date, specifying: 
 (i) the principal amount of the Notes with respect to
which such notice of withdrawal is being submitted; 
 (ii) if Physical Notes have been issued, the certificate
number of the Note in respect of which such notice of withdrawal is being submitted; and 
 (iii) the principal
amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the Notes are Global Notes, the notice must comply with Applicable Procedures. 
 Section 9.03. Deposit of Fundamental Change Repurchase Price. 
 (a)
The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.07 of the Original Indenture) on or
prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase

  
 - 54 -

 
Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close
of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided that the Holder of the Notes has
satisfied the conditions in Section 9.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by
Section 9.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date then: 
 (i) such Notes shall cease to be Outstanding, 
 (ii) interest shall
cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent), and 

(iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change
Repurchase Price and, if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive the related interest
payment). 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 9.01, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered, without payment of any service charge. 

Section 9.04. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer
pursuant to a Fundamental Change Company Notice, the Company shall, if required: 
 (a) comply with the provisions of Rule
13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; 
 (b) file a Schedule TO
or any other required schedule under the Exchange Act; and 
 (c) otherwise comply with all federal and state securities laws in
connection with any offer by the Company to repurchase the Notes; 

  
 - 55 -

 in each case, so as to permit the rights and obligations under this Article IX to be exercised in the time
and in the manner specified in this Article IX. 
 ARTICLE X 

OPTIONAL REDEMPTION 
 Section 10.01. Applicability of Article 3 of the Original Indenture. Article 3 of the Original Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article X
shall, with respect to the Notes, supersede in its entirety Article 3 of the Original Indenture and all references in the Original Indenture to Article 3 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be
deemed to be references to this Article X and the provisions set forth in this Article X. 
 Section 10.02. Right to
Redeem; Notices to Trustee. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company prior to March 8, 2016. On any Business Day on or after March 8, 2016, the Company may redeem (an “Optional
Redemption”) for cash all or part of the Notes, at the Redemption Price, if the Last Reported Sale Price of the Common Stock has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not
consecutive), including the Trading Day immediately preceding the date on which the Company provides the Redemption Notice, during any 30 consecutive Trading Day period ending on the Trading Day prior to the date on which the Company provides the
Redemption Notice in accordance with Section 10.03. 
 Section 10.03. Notice of Optional Redemption; Selection of
Notes.  
 (a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may
be, any part of the Notes pursuant to Section 10.02, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee not less than 65 calendar days prior to the
Redemption Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall provide or cause to be provided a notice of such Optional Redemption (a “Redemption
Notice”) not less than 30 nor more than 60 calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Note Register; provided,
however, that, if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a Business Day. 

(b) The Redemption Notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly
given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity
of the proceedings for the redemption of any other Note. 
 (c) Each Redemption Notice shall specify: 

(i) the Redemption Date; 

  
 - 56 -

 (ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and
that interest thereon, if any, shall cease to accrue on and after the Redemption Date; 
 (iv) the place or
places where such Notes are to be surrendered for payment of the Redemption Price; 
 (v) that Holders may
surrender their Notes for conversion at any time prior to the 5:00 p.m., New York City time, on the Scheduled Trading Day immediately preceding the Redemption Date; 

(vi) the procedures a converting Holder must follow to convert its Notes and the Settlement Method and specified cash
amount, if applicable; 
 (vii) the Conversion Rate and, if applicable, the number of Additional Shares added to
the Conversion Rate in accordance with Section 8.03; 
 (viii) the CUSIP, ISIN or other similar numbers, if
any, assigned to such Notes; and 
 (ix) in case any Note is to be redeemed in part only, the portion of the
principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

A Redemption Notice shall be irrevocable. 
 (d) If fewer than all of the outstanding Notes are to be redeemed and the Notes are in the form of Global Notes, the Depositary will select the Notes to be redeemed. If fewer than all of the outstanding
Notes are to be redeemed and the Notes are in the form of Physical Notes, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another
method the Trustee considers to be fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be
possible) to be the portion selected for redemption. 
 Section 10.04. Payment of Notes Called for Redemption.

 (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 10.03, the
Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption
Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 

  
 - 57 -

 (b) Prior to 9:00 am., New York City time, on the Redemption Date, the
Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 8.02 of the Original Indenture an amount of cash (in
immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be
redeemed shall be made promptly after the later of: 
 (i) the Redemption Date for such Notes; and 

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by this Section 10.04. 
 (c) Upon surrender of a Note that is to be redeemed
in part only pursuant to Section 10.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note surrendered,
without payment of any service charge. 
 Section 10.05. Restrictions on Redemption. The Company may not redeem any
Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of the Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration
resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

 [FORM OF REVERSE OF NOTE] 

RADIAN GROUP INC. 

2.25% Convertible Senior Note due 2019 
 This Note is one of a duly authorized issue of Securities of the Company, designated as its 2.25% Convertible Senior Notes due 2019 (the “Notes”), limited to the aggregate principal
amount of $400,000,000 all issued or to be issued under and pursuant to the Senior Indenture dated as of March 4, 2013 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of
March 4, 2013 (herein called the “Supplemental Indenture”; the Original Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the
“Indenture”), by and between the Company and U.S. Bank National Association (the “Trustee”) to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the
Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of,
and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject
to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture,
the Company will make all payments and deliveries in respect of the Redemption Price, the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to
collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of
the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price, if applicable, of, and accrued and unpaid interest on, and the consideration due upon
conversion of, this Note at the place, at the respective times, in the amounts and, if applicable, in the lawful money herein prescribed. 

 The Notes are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal
amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that
may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture.

 Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company
to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

 Exhibit 10.25 
 SoundBite Communications, Inc. 
 2013 Management Cash Compensation Plan

 Purpose 
 The
purpose of this 2013 Management Cash Compensation Plan (this “Plan”) of SoundBite Communications, Inc. (“SoundBite”) is to provide a balanced compensation package for SoundBite’s management for 2013, in light of
SoundBite’s needs and stage of development. This Plan seeks to establish competitive levels of management compensation, integrate management’s pay with SoundBite’s performance, and facilitate the attraction and retention of qualified
management. This Plan is intended to align management’s financial interests with those of stockholders and to increase stockholder value through continued revenue growth coupled with improved financial performance. This Plan is designed to
focus management on increasing revenue, achieving profitability, and attaining strategic initiatives. The bonus opportunity is tied directly to factors that are expected to increase stockholder value. 

Participants 
 The following
members of management will participate in this Plan: 
  

	 	•	 	 President and Chief Executive Officer 

  

	 	•	 	 Chief Operating Officer and Chief Financial Officer 

  

	 	•	 	 Chief Technology Officer 

  

	 	•	 	 Executive Vice President and General Manager, Mobile Services Business Unit, and Chief Marketing and Business Development Officer

 The President and Chief Executive Officer, the Chief Operating Officer and Chief Financial Officer, and the Chief
Technology Officer are collectively referred to below as the “General Participants,” and the Executive Vice President and General Manager, Mobile Services Business Unit, and Chief Marketing and Business Development Officer is referred to
as the “CMO.” 
 Compensation 
 Compensation for each participant consists of two components: base salary and a variable performance-based bonus. 
 In 2012 the Compensation Committee of SoundBite’s Board of Directors engaged a third-party executive compensation consulting firm to review senior management compensation and to advise the
Compensation Committee with respect to 2013 compensation for senior management, including each of the participants. Based in part on information and advice provided by the compensation consultants, the Compensation Committee established a base
salary and a variable performance-based bonus for each participant after considering a number of factors, including: the status of the competitive marketplace for the participant’s position, including a comparison of base salaries and bonuses
for comparable positions at peer companies of SoundBite; the responsibilities of the position; the level of experience of the participant; and the knowledge required of the participant. 

 

	1.	Base Salary 

 The base
salary of each participant for 2013 is set forth on Schedule 1. 

	2.	Variable Performance-Based Bonus for General Participants 

  

	 	A.	Bonus Target Available 

The aggregate amount of the target bonus available for all General Participants is $427,000 (the “General Bonus Target”).

  

	 	B.	Bonus Target Calculation 

The aggregate amount of the General Bonus Target payable to all General Participants will equal the sum of components for revenue, pro
forma EBITDA, and strategic initiatives and goals, each as described below. 
  

	 	•	 	 Revenue Component: Thirty-three percent of the General Bonus Target ($140,910) will consist of a component based on consolidated revenue
recognized in 2013 in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The revenue component of the General Bonus Target will be earned on an annual basis and will be computed in accordance with a schedule
approved by the Compensation Committee, which schedule shall provide that the revenue component of the General Bonus Target will be payable in full if and only if revenue for 2013 equals or exceeds the amount of revenue reflected in SoundBite’s
operating plan for 2013 (as approved by the Board of Directors, the “Operating Plan”). 

  

	 	•	 	 Pro Forma Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”): Thirty-three percent of the General Bonus Target
($140,910) will consist of a component based on EBITDA for 2013. For these purposes, EBITDA shall be defined as operating income determined in accordance with U.S. GAAP, plus (a) the total amount of expense recorded in accordance with Financial
Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC 718”), (b) the total amount of amortization of intangibles recorded in accordance with U.S. GAAP, (c) the total amount of depreciation expense recorded
in accordance with U.S. GAAP and (d) the total amount of expense recorded in accordance with U.S. GAAP as a result of the EBITDA component for all Plan participants’ Bonus Target. The EBITDA component of the General Bonus Target will be
earned on an annual basis and will be computed in accordance with a schedule approved by the Compensation Committee, which schedule shall provide that the EBITDA component of the General Bonus Target will be payable in full if and only if EBITDA for
2013 equals or exceeds the amount of EBITDA reflected in the Operating Plan plus $162,510 (the amount of the EBITDA component for all Plan participants’ Bonus Target). 

 

	 	•	 	 Strategic Initiatives and Goals Component: Thirty-four percent of the General Bonus Target ($145,180) will consist of a component based upon
strategic initiatives and goals. The General Participants will be provided with group strategic initiatives and goals in order to align the interests of senior management with SoundBite’s stockholders and to build and maintain a cohesive
management team. The Compensation Committee will have full discretion to evaluate and determine the extent to which the Strategic Initiatives and Goals component of the General Bonus Target has been satisfied for 2013, consistent with the
measurement criteria set forth in, or pursuant to, this Plan. 

  

	 	C.	Allocation and Payment of General Bonus Target 

 The General Bonus Target will be allocated among the General Participants in accordance with the percentages set forth under “General Bonus Target—%” on Schedule 1. Payment of the
General Bonus Target amounts to the several General Participants will be due within 30 days

	 	•	 	 MSBU Revenue Component: Fifty percent of the CMO Bonus Target ($54,000) will consist of a component based on MSBU revenue recognized by
SoundBite in 2013 in accordance with U.S. GAAP. The MSBU revenue component of the CMO Bonus Target will be earned on an annual basis and will be computed in accordance with a schedule approved by the Compensation Committee, which schedule shall
provide that such MSBU revenue component will be payable on a commission basis, based on the MSBU revenue earned. Specifically, the amount earned shall equal $54,000 (the applicable CMO Bonus Target), multiplied by a fraction, the numerator of which
shall be the amount of MSBU revenue actually earned in 2013 and the denominator of which shall be the amount of MSBU revenue reflected in the Operating Plan. 

 

	 	•	 	 Revenue Component: Twenty percent of the CMO Bonus Target ($21,600) will consist of a component based on consolidated revenue recognized in 2013
in accordance with U.S. GAAP. The revenue component of the CMO Bonus Target will be earned on an annual basis and will be computed in accordance with a schedule approved by the Compensation Committee, which schedule shall provide that the revenue
component of the CMO Bonus Target will be payable in full if and only if revenue for 2013 equals or exceeds the amount of revenue reflected in the Operating Plan. 

 

	 	•	 	 Pro Forma Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) Component: Twenty percent of the CMO Bonus Target
($21,600) will consist of a component based on EBITDA for 2013. For these purposes, EBITDA shall be defined as operating income determined in accordance with U.S. GAAP, plus (a) the total amount of expense recorded in accordance with ASC 718,
(b) the total amount of amortization of intangibles recorded in accordance with U.S. GAAP, (c) the total amount of depreciation expense recorded in accordance with U.S. GAAP and (d) the total amount of expense recorded in accordance
with U.S. GAAP as a result of the EBITDA component for all Plan participants’ Bonus Target. The EBITDA component of the CMO Bonus Target will be earned on an annual basis and will be computed in accordance with a schedule approved by the

amount of the EBITDA component for all Plan participants’ Bonus Target).

	 	•	 	 Strategic Initiatives and Goals Component: Ten percent of the CMO Bonus Target ($10,800) will consist of a component based upon strategic
initiatives and goals. The participants have been provided with group strategic initiatives and goals in order to align the interests of senior management with SoundBite’s stockholders and to build and maintain a cohesive management team. The
Compensation Committee will have full discretion to evaluate and determine the extent to which the Strategic Initiatives and Goals component of the CMO Bonus Target has been satisfied for 2013, consistent with the measurement criteria set forth in,
or pursuant to, this Plan.
