In connection with the offering of the Underwritten Securities, the Company and one or more financial institutions (the “Call Spread

and the Additional Warrant Confirmations, collectively, the “Additional Call Spread Confirmations” and together with the Base Call Spread Confirmations, the “Call Spread Confirmations”). 

The Company hereby confirms its agreement with the several Initial Purchasers concerning the purchase and sale of the Securities, as follows:

 1.    The Securities will be sold to the Initial Purchasers without being registered under the Securities Act of 1933,
as amended (the “Securities Act”), in reliance upon an exemption therefrom. The Company has prepared a preliminary offering memorandum dated July 9, 2018 (the “Preliminary Offering Memorandum”) and will prepare an
offering memorandum dated the date hereof (the “Offering Memorandum”) setting forth information concerning the Company and the Securities. Copies of the Preliminary Offering Memorandum have been, and copies of the Offering
Memorandum will be, delivered by the Company to the Initial Purchasers pursuant to the terms of this purchase agreement (this “Agreement”). The Company hereby confirms that it has authorized the use of the Preliminary Offering
Memorandum, the other Time of Sale Information (as defined below) and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. References herein to
the Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum shall be deemed to refer to and include any document incorporated by reference therein and any reference to “amend,” “amendment” or
“supplement” with respect to the Preliminary Offering Memorandum and the Offering Memorandum shall be deemed to refer to and include any documents filed after such date and incorporated by reference therein. 

At or prior to 8:05 a.m. New York City time on July 10, 2018 (the “Time of Sale”), the Company had prepared the following

2.    Purchase and Resale of the Securities by the Initial Purchasers. (a) The Company agrees to issue and
sell the Underwritten Securities to the several Initial Purchasers as provided in this Agreement, and each Initial Purchaser, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth
herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Underwritten Securities set forth opposite such Initial Purchaser’s name in Schedule 1 hereto at a price equal to 99.00% of the principal

 In addition, the Company agrees to issue and sell the Option Securities to the several Initial
Purchasers as provided in this Agreement, and the Initial Purchasers, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and
not jointly, from the Company the Option Securities at the Purchase Price plus accrued interest, if any, from July 12, 2018 to the date of payment and delivery. 

If any Option Securities are to be purchased, the amount of Option Securities to be purchased by each Initial Purchaser shall be the amount of
Option Securities which bears the same ratio to the aggregate amount of Option Securities being purchased as the amount of Underwritten Securities set forth opposite the name of such Initial Purchaser in Schedule 1 hereto (or such amount increased
as set forth in Section 10 hereof) bears to the aggregate amount of Underwritten Securities being purchased from the Company by the several Initial Purchasers, subject, however, to such adjustments to eliminate Securities in denominations other
than $1,000 as the Representatives in their sole discretion shall make. 
 The Initial Purchasers may exercise the option to purchase the
Option Securities solely to cover over-allotments at any time in whole, or from time to time in part, on or before the thirtieth day following the date of this Agreement, by written notice from the Representatives to the Company. Such notice shall
set forth the aggregate amount of Option Securities as to which the option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date (as hereinafter
defined) but shall not be earlier than the Closing Date nor later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10
hereof). Except as separately agreed in writing by the Company and the Representatives, any such notice shall be given at least two business days prior to the date and time of delivery specified therein (except in the case of any Option Securities
to be delivered on the Closing Date, in which case notice shall be delivered at least one business day prior to the Closing Date).

(ii)    it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or
sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act;
and 

  
 3 

 (iii)    it has not solicited offers for, or offered or sold,
and will not solicit offers for, or offer or sell, the Securities as part of their initial offering except within the United States to persons whom it reasonably believes to be QIBs in transactions pursuant to Rule 144A under the Securities Act
(“Rule 144A”) and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A. 

(c)    Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the opinions to be delivered to
the Initial Purchasers pursuant to Sections 6(e) and 6(f), counsel for the Company and counsel for the Initial Purchasers, respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by
the Initial Purchasers with their agreements, contained in paragraph (b) above, and each Initial Purchaser hereby consents to such reliance. 

(d)    The Company acknowledges and agrees that the Initial Purchasers may offer and sell Securities to or through any

that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that
the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an
Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel
to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to
retain its own counsel, but the fees and expenses of such counsel shall be at the 

  
 23 

 
expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed
within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition
to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be
liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any
Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers and any control
persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the
Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such
settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does
not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 

(d)    Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an
Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial
Purchasers, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to
in clause (i) but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting
expenses, but after deducting discounts and commissions) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection

  
 24 

 
therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other,
shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial
Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e)    Limitation on Liability. The Company and the Initial Purchasers agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be
required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser
has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase
obligations hereunder and not joint. 
 (f)    Non-Exclusive Remedies. The
remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. 

8.    Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by
the parties hereto. 
 9.    Termination. This Agreement may be terminated in the absolute discretion of the
Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date (i) trading generally shall have been
suspended or materially limited on or by any of The New York Stock Exchange or The Nasdaq Global Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there
shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes
it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale
Information and the Offering Memorandum. 

  
 25 

 10.    Defaulting Initial Purchaser. (a) If, on the Closing Date
or the Additional Closing Date, as the case may be, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Initial
Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion
of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or
supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise
requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase. 

(b)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or
Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the
Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the number of Securities that such Initial Purchaser agreed to purchase hereunder on such date plus such Initial Purchaser’s pro rata share (based on the number of
Securities that such Initial Purchaser agreed to purchase on such date) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made. 

(c)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or
Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the
Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph
(b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Initial Purchasers to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part

  
 26 

 
of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the
Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect. 

(d)    Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or
any non-defaulting Initial Purchaser for damages caused by its default. 

11.    Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are
consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization,
issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer
Written Communication and the Offering Memorandum (including any amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and
expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such
jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); provided that, such fees shall not
exceed $2,500; (vi) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (vii) all expenses and application fees incurred in connection with the approval of the
Securities for book-entry transfer by DTC; (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (ix) all expenses and application fees related to the listing of
the Conversion Shares and the Warrant Shares on the Exchange. 
 (b)    If (i) this Agreement is terminated pursuant
to Section 9 (other than pursuant to clause (i), (iii) or (iv) of Section 9), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to
purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses
(including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby. 

12.    Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or
equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase. 

  
 27 

 13.    Survival. The respective indemnities, rights of contribution,
representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto
shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Initial Purchasers. 

14.    Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided,
the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York
City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in
Rule 1-02 of Regulation S-X under the Exchange Act and consists of the entities listed on Schedule 2 hereto. 

15.    Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which
information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients. 

16.    Miscellaneous. (a) Notices. All notices and other communications hereunder shall be in writing
and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Initial Purchasers shall be given to the Representatives c/o Citigroup Global Markets Inc., 388 Greenwich

standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument. 

  
 28 

 (d)    Amendments or Waivers. No amendment or waiver of any provision
of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

	1.	The Company is a corporation duly incorporated and validly existing under the laws of the State of Delaware and is in good standing under such laws. The Company has requisite corporate power to own or lease its
properties and carry on its business, as described in the Final Offering Memorandum. The Company is qualified to do business as a foreign corporation in the State of California. 

 

	2.	The execution and delivery of the Operative Documents have been duly authorized by all necessary corporate action on the part of the Company, and the Purchase Agreement has been duly executed and delivered by the
Company. 

  

	3.	The Company has the corporate power to execute and deliver the Operative Documents and to perform its obligations under the terms of the Operative Documents. 

 

	4.	The Securities being issued on the date hereof are in the form contemplated in the Indenture and have been duly authorized by all necessary corporate action of the Company and have been duly executed by the Company and
when authenticated by the Trustee in accordance with the terms of the Indenture (which authentication we have not determined by inspection of the Securities) and issued and delivered to the Initial Purchasers against payment of the purchase price
therefor specified in the Purchase Agreement, the Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms. 

 

	5.	The Indenture has been duly authorized by all necessary corporate action on the part of the Company and the Indenture has been duly executed and delivered by the Company and, assuming the due authorization, execution
and delivery thereof by the Trustee, the Indenture constitutes a valid and binding instrument, enforceable against the Company in accordance with its terms. 

  

	6.	The shares of Common Stock initially issuable upon conversion of the Securities (assuming full physical settlement of the Securities and including shares of Common Stock issuable with respect to any Make-Whole
Fundamental Change (as defined in the Indenture)) (the “Shares”) have been duly authorized by all necessary corporate action on the part of the Company and the Shares, if any, when issued upon due conversion of the Securities in accordance
with the terms of the Securities and the Indenture would, if issued today, be validly issued, fully paid and nonassessable and free of preemptive rights arising under the Certificate of Incorporation or Bylaws or the DGCL. 

	7.	The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Description of Notes” insofar as such statements purport to constitute a summary of the terms of
the Indenture and the Securities, fairly summarize such terms in all material respects. 

  

	8.	The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Certain U.S. Federal Income Tax Considerations,” insofar as they purport to summarize the United
States federal tax laws referred to therein or legal conclusions with respect thereto, are fair summaries in all material respects. 

  

	9.	The statements set forth in the General Disclosure Package and Final Offering Memorandum under the caption “Description of Capital Stock,” insofar as such statements constitute summaries of legal matters or
documents, fairly summarize the matters and documents referred to therein in all material respects. 

  

	10.	The Company is not, and immediately after giving effect to the offering and sale of the Securities and the application of the net proceeds thereof as described in the Final Offering Memorandum, will not be required to
be registered as, an “investment company,” as such term is defined in the Investment Company Act. 

  

	11.	None of the issuance and sale of the Securities being delivered on the date hereof, the execution, delivery and performance by the Company of its obligations under the Purchase Agreement, the Indenture and the
Securities or the consummation of the transactions contemplated thereby will (i) violate the Certificate of Incorporation or Bylaws, (ii) conflict with, result in a breach or violation by the Company of any of the terms or provisions of,
or constitute a default by the Company under any Reviewed Agreement, or (iii) result in a violation of any Reviewed Judgment. 

  

	12.	No consent, approval, authorization, order, registration or qualification of or with any U.S. federal, New York, California or Delaware (solely with respect to the DGCL) governmental agency or body or court is required
for the execution and delivery of the Purchase Agreement, the offer and sale by the Company of the Securities or the consummation by the Company of the transactions contemplated by the Purchase Agreement or the Indenture, except (i) such as
have been obtained under the Securities Act, (ii) such as may be required under state securities or Blue Sky laws, and (iii) as contemplated by the Operative Documents. 

	13.	Assuming the accuracy of the Initial Purchasers’ representations contained in the Purchase Agreement and the accuracy of the Company’s representations contained in the Purchase Agreement, no registration of
the Securities or the Shares is required under the Securities Act for the sale of the Securities by the Company to the Initial Purchasers pursuant to the Purchase Agreement and the Indenture or for the initial resale of the Securities by the Initial
Purchasers in the manner contemplated by the Purchase Agreement, the General Disclosure Package and the Final Offering Memorandum, and it is not necessary to qualify the Indenture under the Trust Indenture Act (it being understood that, in each
case, no opinion is expressed as to any subsequent resale of the Securities or the Shares or the consequences thereof).

to certain conditions, holders of notes may require us to repurchase for cash all or part of their notes in principal amounts of $1,000 or a multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of
the notes to be

	Pricing Date:	  	July 10, 2018.
		
	Trade Date:	  	July 10, 2018.
		
	Expected Settlement Date:	  	July 12, 2018 (T+2).
		
	CUSIP Number (144A):	  	697435 AC9
		
	ISIN (144A):	  	US697435AC95
		
	Listing:	  	None.
		
	Net Proceeds:	  	We estimate that the net proceeds from this

			
		  	offering will be approximately $1.48 billion (or $1.70 billion if the initial purchasers exercise their over-allotment option in full), after deducting fees and estimated offering expenses payable by us.
		
	Use of Proceeds:	  	 We entered into convertible note hedge transactions with certain of the initial purchasers or their respective affiliates or other financial
institutions, whom we refer to as the option counterparties. We also entered into warrant transactions with the option counterparties. We intend to use $165.3 million of the net proceeds from this offering to pay the cost of the convertible
note hedge transactions (after such cost is partially offset by the proceeds to us from the warrant transactions). We intend to use the remainder of the net proceeds from this offering for general corporate purposes, which may include working
capital, capital expenditures, potential acquisitions, strategic transactions, the payment of amounts due upon conversion, at maturity or upon repurchase of our outstanding 2019 notes and repurchases of our common stock pursuant to our stock
repurchase program.
  
 If the over-allotment option granted to the initial purchasers
is exercised with respect to additional notes, we may sell additional warrants and use a portion of the net proceeds from the sale of such additional notes, together with the proceeds from the sale of additional warrants, to enter into additional
convertible note hedge transactions relating to the additional notes. We expect to use the remaining net proceeds from the sale of the additional notes, together with the remaining proceeds from the sale of the additional warrants, for general
corporate purposes. See “Use of Proceeds” in the Preliminary Offering Memorandum.

		
	Convertible Note Hedge and Warrant Transactions:	  	 In connection with the pricing of the notes, we entered into privately negotiated convertible note hedge transactions with the option
counterparties. The convertible note hedge transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the notes, the number of shares of our common stock that initially underlie the
notes. We also entered into warrant transactions with the option counterparties relating to the same number of shares of our common stock that underlie the notes, with a strike price of $417.80, subject to customary anti-dilution adjustments.

 
 The convertible note hedge transactions are expected generally to reduce potential
dilution to our common stock upon any conversion of notes and/or offset any cash payments we are required

			
		  	 to make in excess of the principal amount of any converted notes, as the case may be. However, the warrant transactions could separately have
a dilutive effect to the extent that the market value per share of our common stock exceeds the applicable strike price of the warrants unless, subject to certain conditions, we elect to cash settle the warrants.

 
 If the initial purchasers exercise their over-allotment option, we expect to enter into
additional convertible note hedge and warrant transactions with the option counterparties relating to the additional notes.
  

In connection with establishing their initial hedge of the convertible note hedge and warrant transactions, the option counterparties or their respective
affiliates expect to purchase shares of our common stock and/or enter into various derivative transactions with respect to our common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size
of any decrease in) the market price of our common stock or the notes at that time.
  

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with
respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during any
observation period related to a conversion of the notes). This activity could also cause or avoid an increase or a decrease in the market price of our common stock or the notes, which could affect your ability to convert the notes and, to the extent
the activity occurs during any observation period related to a conversion of notes, it could affect the amount and value of the consideration that you will receive upon conversion of the notes.

 Description of Notes—Conversion Rights—Increase in Conversion Rate upon
Conversion upon A 
 Make-Whole Fundamental Change 

Holders who convert their notes in connection with a “make-whole fundamental change” (as defined in the Preliminary Offering Memorandum) occurring
prior to the maturity date may be entitled to an increase in the conversion rate for the notes so surrendered for conversion. 
 The following table sets
forth the number of additional shares by which the conversion rate will be increased per $1,000 principal amount of notes 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: 

 

	 	•	 	If the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares by which the conversion rate will be increased will be
determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day
year. 

  

	 	•	 	If the stock price is greater than $600.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the
conversion rate. 

  

	 	•	 	If the stock price is less than $208.90 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion
rate. 

 Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of notes exceed 4.7869 shares of
common stock, subject to adjustment in the same manner as the conversion rate as set forth under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering Memorandum. 

Our obligation to increase the conversion rate for notes converted in connection with a make-whole fundamental change could be considered a penalty, in which
case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

the Indenture section numbers used herein are based on the [draft of the Indenture last reviewed by Dealer as of the date of this Confirmation, and if any such section numbers are changed in the Indenture as executed, the parties will amend this
Confirmation in good faith to preserve the intent of the parties]7[Indenture as executed]8. Subject to the foregoing, references to the
Indenture herein are references to the Indenture as in effect on the date of its execution, and if the Indenture is amended following such date (other than any amendment pursuant to Section 10.01(j) of the Indenture that, as determined by the
Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum), any such amendment will be disregarded for purposes of this Confirmation unless the parties agree otherwise in writing.

Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty has provided a Notice of Exercise to Dealer in accordance with “Notice of Exercise” below;
provided further that if the Trustee or any other such agent on behalf of Counterparty provides such Notice of Exercise to Dealer, Dealer shall be entitled to rely on the accuracy of such Notice of Exercise without any independent
investigation.
		
		  	Notwithstanding the foregoing, in no event shall the number of Relevant Options that are exercised or deemed exercised hereunder exceed the Number of Options.
		
	 Notice of Exercise:
	  	Notwithstanding anything to the contrary in the Equity Definitions or under “Automatic Exercise” above, in order to exercise any Options, Counterparty or the Trustee (or other agent authorized by Counterparty and
previously identified to Dealer by Counterparty in writing) on behalf of Counterparty must notify Dealer in writing before 5:00 p.m. (New York City time) on the Scheduled Valid Day immediately preceding the scheduled first day of the Settlement

		 	amount of Convertible Notes outstanding on such date immediately prior to such conversion (upon which Dealer shall be entitled to rely on the accuracy of such amount without any independent investigation), (ii) the scheduled first
day of the Settlement Averaging Period and the scheduled Settlement Date, (iii) the Relevant Settlement Method for such Options, and (iv) if the Relevant Settlement Method is Combination Settlement, the percentage of the consideration due
upon conversion per Convertible Note in excess of the principal amount thereof that Counterparty has elected to pay to Holders (as such term is defined in the Indenture) of the Relevant Convertible Notes in cash (the “Cash
Percentage”); provided that notwithstanding the foregoing, in respect of any Options relating to Relevant Convertible Notes with a Conversion Date occurring prior to the Free Convertibility Date, such notice (and the related exercise
of Options) shall be effective if given after the Exercise Notice Deadline, but prior to 4:00 p.m. (New York City time) on the fifth Scheduled Valid Day following the Exercise Notice Deadline, in which event the Calculation Agent shall have the
right to adjust the delivery obligation under this Confirmation as appropriate to reflect the commercially reasonable additional costs (including, but not limited to, additional costs related to hedging mismatches and market losses and gains) and
commercially reasonable expenses incurred by Dealer in connection with commercially reasonable hedging activities (including the unwinding of any commercially reasonable Hedge Positions) as a result of Dealer not having received such notice on or
prior to the Exercise Notice Deadline and Dealer’s obligation to make any payment or delivery in respect of such exercise shall not be extinguished; and provided further that in respect of any Options relating to Relevant
Convertible Notes with a Conversion Date occurring on or after the Free Convertibility Date, (A) such notice may be given on or prior to the second Scheduled Valid Day immediately preceding the Expiration Date and need only specify the
information required in clause (i) above, and (B) if the Relevant Settlement Method for such Options is (x) Cash Settlement or (y) Combination Settlement, Dealer shall have received a separate notice (the “Notice of Final
Settlement Method”) in respect of all such Convertible Notes before 5:00 p.m. (New York City time) on the Free Convertibility Date specifying the information required in clause (iii) and, if applicable, clause (iv) above.
Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act (as defined below) and the rules and regulations thereunder, in respect of any election of a
settlement method with respect to the Convertible Notes. The parties hereto agree and acknowledge that if the Trustee or any other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing on behalf of

  
 5 

			
		
		  	Counterparty provides notice to Dealer as provided for in the second immediately preceding sentence, Dealer shall be entitled to rely on the accuracy of such notice without any independent investigation.
		
	 Valuation Time:
	  	At the close of trading of the regular trading session on the Exchange; provided that if the principal trading session is extended, the Calculation Agent shall determine the Valuation Time in good faith and in a commercially
reasonable manner.
		
	 Market Disruption Event:
	  	Section 6.3(a) of the Equity Definitions is hereby replaced in its entirety by the following:
		
		  	“‘Market Disruption Event’ means, in respect of a Share, (i) a failure by the primary United States national or regional securities exchange or market on which the Shares are listed or admitted for trading to
open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m. (New York City time) on any Scheduled Valid Day for the Shares for more than one half-hour period in the aggregate during regular trading
hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Shares or in any options contracts or futures contracts relating to the
Shares.”
		
	 Settlement Terms.
	  	
		
	 Settlement Method:
	  	For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement
Method, but only if Counterparty, or the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty, shall have notified Dealer of the Relevant Settlement Method in
the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option. The parties hereto agree and acknowledge that if the Trustee or any other agent authorized by Counterparty and previously identified to Dealer by
Counterparty in writing on behalf of Counterparty provides notice to Dealer as provided for in the proviso to the immediately preceding sentence, Dealer shall be entitled to rely on the accuracy of such notice without any independent
investigation.
		
	 Relevant Settlement Method:
	  	In respect of any Option:
		
		  	(i) if Counterparty has not elected to settle all or any portion of its conversion obligations in respect of the Relevant Convertible Note in excess of its principal amount in cash either by specifying a Cash Percentage of 0% or not
timely specifying a Cash Percentage, in each case, pursuant to Section 14.02(a)(i) of the Indenture, then the Relevant Settlement Method for such Option shall be Net Share Settlement; and

  
 6 

			
		  	(ii) if Counterparty has elected to settle its conversion obligations in respect of the Relevant Convertible Note in excess of its principal amount in a combination of cash and Shares by specifying a Cash Percentage less than 100%
but greater than 0% pursuant to Section 14.02(a)(i) of the Indenture, then the Relevant Settlement Method for such Option shall be Combination Settlement; and
		
		  	(iii) if Counterparty has elected to settle its conversion obligations in respect of the Relevant Convertible Note in excess of its principal amount entirely in cash by specifying a Cash Percentage of 100% pursuant to
Section 14.02(a)(i) of the Indenture (such settlement method, “Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement.
		
	 Net Share Settlement:
	  	If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share
Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid
Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such
Option, divided by the Applicable Limit Price on the Settlement Date for such Option.
		
		  	Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
		
	 Combination Settlement:
	  	If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:
		
		  	 (i) cash (the “Combination Settlement Cash Amount”) equal to the sum, for
each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the product of (1) the Cash Percentage and (2) the Daily Option Value,
divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash
Amount for such Valid Day shall be deemed to be zero; and

  
 7 

			
		
		  	 (ii)  Shares (the “Combination Settlement Share Amount”) equal to the
sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid
Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period;
provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be
zero;

		
		  	provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, and (y) the Combination Settlement Share Amount for such Option, multiplied by the Applicable Limit Price
on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
		
		  	Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging
Period.
		
	 Cash Settlement:
	  	If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an
amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number
of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount exceed the Applicable Limit for such Option.
		
	 Daily Option Value:
	  	For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the
calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.

	 Early Termination upon a Make-Whole Fundamental Change:
	  	Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the
Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference
to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the
Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be
payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction
and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess, with such reduction first being
made to any Shares deliverable hereunder.
		
	 Applicable Limit:
	  	For any Option, an amount of cash equal to the Applicable Percentage, multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the Relevant Convertible Note upon
conversion of such Convertible Note as determined pursuant to Section 14.02(a) of the Indenture and (B) the number of Shares, if any, delivered to the Holder of the Relevant Convertible Note upon conversion of such Convertible Note as
determined pursuant to Section 14.02(a) of the Indenture, multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

	  	On any day, the opening price as displayed under the heading “Op” on Bloomberg page PANW <equity> (or any successor thereto).
		
	 Valid Day:

regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a United States national or regional securities exchange, on the principal other market on which the Shares are then listed or admitted for
trading. If the Shares are not so listed or admitted for trading, “Valid Day” means a Business Day.
		
	 Scheduled Valid Day:
	  	A day that is scheduled to be a Valid Day on the principal United States national or regional securities exchange or market on which the Shares are listed or admitted for trading. If the Shares are not so listed or admitted for

of the period from the scheduled opening time of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Valid Day, as determined by
the Calculation Agent in good faith and in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the
regular trading session trading hours.
		
	 Settlement Averaging Period:
	  	For any Option and regardless of the Settlement Method applicable to such Option:
		
		  	 (i) if the related Conversion Date occurs prior to the Free Convertibility Date, the 30
consecutive Valid Days commencing on, and including, the second Valid Day following such Conversion Date; or

	  	For any Option, the date cash is paid and Shares, if any, are delivered under the terms of the Indenture with respect to the conversion of the Convertible Note related to such Option.
		
	 Settlement Currency:
	  	USD
		
	 Other Applicable Provisions:
	  	The provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share
Settled”. “Share Settled” in relation to any Option means that Net Share Settlement or Combination Settlement is applicable to that Option.
		
	 Representation and Agreement:
	  	Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery,
subject to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of
delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities

adjustment under the Indenture to the “Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price” , “Daily VWAP,” “Daily Conversion Value” or
“Daily Net Settlement Amount” (each as defined in the Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account
of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate,
in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Indenture or the fourth sentence
of Section 14.04(d) of the Indenture).
		
	 Method of Adjustment:
	  	Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make a corresponding adjustment to any one or more of
the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided that, notwithstanding the foregoing, if the Calculation Agent acting in good faith
and in a commercially reasonable manner disagrees with any adjustment pursuant to the terms and provisions of the Indenture that is the basis of any calculation hereunder and that involves an exercise of discretion by Counterparty or its board of
directors (including, without limitation, pursuant to Section 14.05 of the Indenture or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each
such case, the Calculation Agent will determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a
commercially reasonable manner.

	 Tender Offers:
	  	Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment
under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction;
provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate determined pursuant to any Excluded Provision; provided further that if, with respect to a Merger Event or a Tender
Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or
the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer, will not be a corporation or will not be the Issuer following such Merger Event or Tender Offer, then Cancellation and Payment
(Calculation Agent Determination) may apply at Dealer’s sole election.
		
	 Nationalization, Insolvency or Delisting:
	  	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located
in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange,
The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the
Exchange.

limited to, stock price and volatility risk. And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms.”; and

		
		  	 (ii)  Section 12.9(b)(iii) of the Equity Definitions is hereby amended by

obligation, as the case may be, and ending on the earlier of the Early Termination Date with respect to such Event of Default and the date on which such Event of Default is no longer continuing, as the Calculation Agent.

	 	(v)	Counterparty is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares. 

 

	 	(vi)	Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise
independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million. 

 

	 	(b)	Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the
“CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA). 

  

	9.	Other Provisions. 

  

	 	(a)	Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to due incorporation, existence and good standing of Counterparty in Delaware, the due
authorization, execution and delivery of this Confirmation, and, in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to
Counterparty’s Annual Report on Form 10-K, Counterparty’s certificate of incorporation or Counterparty’s by-laws. Delivery of such opinion to Dealer shall
be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement. 

  
 16 

	 	(b)	Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”)
on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than [    ]15 million (in the case of the first such
notice) or (ii) thereafter more than [    ]16 million less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to
indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses
(including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of
hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become
subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for
any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental
or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified
Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty
may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its
written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment.
Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is a party and
indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms
reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then
Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in
this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain
operative and in full force and effect regardless of the termination of the Transaction. 

  

	 	(c)	Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day
immediately following the Effective Date, engage in any such distribution. 

  

	15 	Insert the number of Shares outstanding that would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is
exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by 0.5%, based on dealer with highest Applicable Percentage. 

	16 	Insert the number of Shares that, if repurchased, would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares underlying any additional transaction if the
greenshoe is exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by a further 0.5% from the threshold for the first Repurchase Notice, based on dealer
with highest Applicable Percentage. 

  
 17 

	 	(d)	No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to
manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act. 

  

	 	(e)	Transfer or Assignment. 

  

	 	(i)	Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”);
provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions: 

 

	 	(A)	With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(m) or 9(r) of this
Confirmation; 

  

	 	(B)	Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended); 

 

	 	(C)	Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws
in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by
such third party and Counterparty, as are requested and reasonably satisfactory to Dealer; 

  

	 	(D)	Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have
been required to pay to Counterparty in the absence of such transfer and assignment; 

  

	 	(E)	An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; 

  

	 	(F)	Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit
Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and 

  

	 	(G)	Counterparty shall be responsible for all commercially reasonable costs and expenses, including commercially reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment. 

 

	 	(ii)	 Dealer may, without Counterparty’s consent, transfer or assign (such transfer or assignment, a
“Transfer”) all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time
of such Transfer, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or Dealer’s ultimate parent, or (B) to any
other third party with a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the Transfer and (2) A- by Standard and Poor’s Rating Group,
Inc. or its successor (“S&P”), or A3 by Moody’s Investor 

  
 18 

	 	
Service, Inc. (“Moody’s”) or, if either S&P or Moody’s ceases to rate such third party, at least an equivalent rating or better by a substitute rating
agency mutually agreed by Counterparty and Dealer; provided that Dealer shall provide notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (B) the Option Equity
Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its
commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists,
then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position
exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated
in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial
termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as
if Counterparty was not the Affected Party).    The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares
that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of
Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the
equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The
“Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate
number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that
Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of
Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of
ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting
or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer
in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. 

  

	 	(iii)	Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or
from Counterparty, Dealer may designate any of its affiliates (each, a “Dealer Designated Affiliate”) to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise
to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty under this Confirmation to the extent such Dealer Designated
Affiliate fully performs the obligations designated by Dealer to such Dealer Designated Affiliate under this Section 9(e)(iii). 

  
 19 

	 	(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities
hereunder that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire
Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to
deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows: 

  

	 	(i)	in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th)
Exchange Business Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date; 

  

	 	(ii)	the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal
Settlement Date; and 

  

	 	(iii)	if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case
may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause
(i) above. 

  

	 	(g)	[Role of Agent. [Insert agency language for particular Dealer, if applicable.]][Reserved.] 

 

	 	(h)	Submission to Jurisdiction. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN
CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS. 

  

	 	(i)	Additional Termination Events. 

  

	 	(i)	Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture, then
such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the
Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. 

 

	 	(ii)	 Promptly (and in any event within five Scheduled Trading Days) following any repurchase (which, for the avoidance
of doubt, includes any exchange transaction) and cancellation of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture) (such event, a
“Repurchase Event”), Counterparty may notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”). Notwithstanding
anything to the 

  
 20 

	 	
contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a
written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the
Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day
following receipt of such Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repurchase Event) as an Early Termination Date with respect
to the portion of this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice [minus the number of
“Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes] divided by the Applicable Percentage and (B) the Number of Options as of the date Dealer designates such
Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repurchase Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if
(1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with
respect to such Additional Termination Event, (3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible
Notes remaining outstanding as if the circumstances related to the Repurchase Event had not occurred, (5) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of
Counterparty leading thereto had not occurred, and (6) the terminated portion of the Transaction were the sole Affected Transaction. 

  

	 	(j)	Amendments to Equity Definitions. 

  

	 	(i)	Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and
(2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master
Agreement with respect to that Issuer.” 

  

	 	(ii)	Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party”
with “notice to Counterparty” in the first sentence of such section. 

  

	 	(k)	No Setoff. Neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it, whether arising
under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise. 

  

	 	(l)	 Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If
(a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an
Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within
Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in
Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of 

  
 21 

	 	
the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to
Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation
by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger
Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply,
(b) Counterparty remakes the representation set forth in Section 8(a)(v) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or
Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply. 

  

			
	 Share Termination Alternative:
	  	If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant
to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.
		
	 Share Termination Delivery Property:
	  	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery
Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
		
	 Share Termination Unit Price:
	  	The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in good faith and in a commercially reasonable manner and notified by the Calculation Agent to Dealer at the
time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of
Share Termination Delivery Property.
		
	 Share Termination Delivery Unit:
	  	One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the
“Exchange Property”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of
any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

  
 22 

			
	 Failure to Deliver:
	  	Applicable
		
	 Other applicable provisions:
	  	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in
Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as
references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

  

	 	(m)	Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the
Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the
foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein. 

 

	 	(n)	Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the
purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the
Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in customary form and substance reasonably satisfactory to Dealer, substantially in the form of
an underwriting agreement for a registered secondary offering of equity securities of comparable size of companies of comparable size, maturity and line of business; provided, however, that if Dealer, in its sole reasonable discretion,
is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this paragraph
shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for
private placements of equity securities of comparable size of companies of comparable size, maturity and line of business, in customary form and substance that is commercially reasonable and reasonably satisfactory to Dealer (in which case, the
Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge
Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer. 

 

	 	(o)	Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all
persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax
structure. 

  
 23 

	 	(p)	Right to Extend. Dealer may postpone or add, in a commercially reasonable manner, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation,
payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in its reasonable discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially
reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder
in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer;
provided that in no event shall Dealer have the right to so postpone or add any Valid Day(s) or any such other date beyond the 30th Valid Day immediately following the last Valid Day of the relevant Settlement Averaging Period (determined
without regard to this Section 9(o)). 

  

	 	(q)	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior
to the claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a
breach by Counterparty of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the
Transaction. 

  

	 	(r)	Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title
11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code,
(ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described
in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy
Code. 

  

	 	(s)	Notice of Certain Other Events. Counterparty covenants and agrees that: 

  

	 	(i)	promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written
notice of the weighted average of the types and amounts of consideration actually received by holders of Shares (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the
Consideration Notification Date be later than the date on which such Merger Event is consummated; and 

  

	 	(ii)	promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer, Counterparty shall give Dealer written notice of the details of such
adjustment. 

  

	 	(t)	Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that
neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend
or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or
the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)). 

  
 24 

	 	(u)	Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or
sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be
active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of

provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such

terms of the Convertible Notes or the Indenture) to take into account the effect of an event, the Calculation Agent or Determining Party (as the case may be) shall make such adjustment by reference to the effect of such event on the Hedging Party,
