 In connection with the offering of the Underwritten Securities, the Company and one or
more financial institutions (the “Call Spread Counterparties”) are entering into convertible note hedge transactions and warrant transactions pursuant to convertible note hedge confirmations (the “Base Bond Hedge
Confirmations”) and warrant confirmations (the “Base Warrant Confirmations”), each dated the date hereof (the Base Bond Hedge Confirmations and the Base Warrant Confirmations, collectively, the “Base Call Spread
Confirmations”), and in connection with the issuance of any Option Securities, the Company and the Call Spread Counterparties may enter into additional convertible note hedge transactions and additional warrant transactions pursuant to
additional convertible note hedge confirmations (the “Additional Bond Hedge Confirmations”) and additional warrant confirmations (the “Additional Warrant Confirmations”), each to be dated the date of the exercise by
the Initial Purchasers of their option to purchase such Option Securities pursuant to Section 2 hereof (the Additional Bond Hedge Confirmations 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 June 23, 2014 (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 7:00 p.m. New York City time on June 24, 2014 (the “Time of Sale”), the Company had prepared the
following information (collectively, the “Time of Sale Information”): the Preliminary Offering Memorandum, as supplemented and amended by the written communications listed on Annex A hereto.  

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 

  
 2 








 
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 97.5% of the principal amount thereof (the “Purchase Price”). 

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. 
 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). 

(b) The Company understands that the Initial Purchasers intend to offer the Securities for resale on the terms set forth in the Time of Sale
Information. Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

 (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 
 (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 affiliate of an Initial Purchaser and that any such affiliate may offer and sell Securities purchased by it to or through any Initial
Purchaser; provided that such offers and sales shall be made in accordance with the provisions of this Agreement. 
 (e) Payment for
the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives in the case of the Underwritten Securities, at the offices of Davis Polk & Wardwell LLP, 1600 El
Camino Real, Menlo Park, California at 10:00 A.M. New York City time on June 30, 2014, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may
agree upon in writing or, in the case of the Option Securities, on the date and at the time and place specified by the Representatives in the written notice of the Initial Purchasers’ election to purchase such Option Securities. The time and
date of such payment for the Underwritten Securities is referred to herein as the “Closing Date” and the time and date for such payment for the Option Securities, if other than the Closing Date, is herein referred to as the
“Additional Closing Date”. 
 Payment for the Securities to be purchased on the Closing Date or the
Additional Closing Date, as the case may be, shall be made against delivery to the nominee of The Depository Trust Company (“DTC”), for the respective accounts of the several Initial Purchasers of the Securities to be purchased on
such date of one or more global notes representing the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of such Securities duly paid by the Company. The Global Note will be

counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any

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 

  
 23 








 
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

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 

  
 24 








 
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 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 

  
 25 








 
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. 

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 

  
 26 








 
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 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. 

  
 27 








 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. 

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;

 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.

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 J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York

 PRICING TERM SHEET 

DATED JUNE 24, 2014 
  





 
 PALO ALTO NETWORKS, INC. 

$500,000,000 PRINCIPAL AMOUNT OF 

0% CONVERTIBLE SENIOR NOTES DUE 2019

only to Palo Alto Networks, Inc. and not to its consolidated subsidiaries. Terms used herein but not defined herein shall have the respective meanings as set forth in the Preliminary Offering Memorandum. All references to dollar amounts are
references to U.S. dollars.

subject to certain conditions, holders 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 repurchased, plus any accrued and unpaid special interest to, but excluding, the fundamental change repurchase date. See “Description of notes—Fundamental change permits holders to require us to repurchase notes” in
the Preliminary Offering Memorandum.
		
	No regular interest; Special interest:	  	 0% per year.
  

The notes will not accrue interest, and the principal amount of the notes will not accrete. We will pay special interest, if any, at our election as the sole
remedy relating to the failure to comply with our reporting obligations as described under “Description of notes—Events of default” and under the circumstances described under “Description of notes—No registration rights;
special interest” in the Preliminary Offering Memorandum.

	Net proceeds:	  	We estimate that the net proceeds from this offering will be approximately $486.4 million (or $559.5 million 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, whom we refer
to as the option counterparties. We also entered into warrant transactions with the option counterparties. We intend to use approximately $28.5 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 and strategic transactions.
  
 If the initial purchasers exercise
their over-allotment option, we expect to sell additional warrants and use a portion of the net proceeds from the sale of the additional notes, together with the proceeds from the additional warrants, to enter into additional convertible note hedge
transactions and for general corporate purposes. Any remaining net proceeds from the sale of additional notes will be used 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, with a strike price of $137.8475, 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.
  

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.
  
 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 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.

Preliminary Offering Memorandum.

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 $250.00 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 $78.77 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 12.6951 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. 







 Capitalization 

The following table sets forth our cash, cash equivalents and short-term investments and capitalization as of April 30, 2014: 

 

	 	•	 	on an actual basis; and 

  

	 	•	 	on an as adjusted basis to give effect to (1) the issuance and sale of the notes in this offering (assuming the initial purchasers’ over-allotment option is not exercised), after deducting fees and estimated
offering expenses payable by us, and (2) the use of approximately $28.5 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. 

 This table should be read in conjunction with the section titled “Use of proceeds” in the Preliminary
Offering Memorandum and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Quarterly Report on Form 10-Q for our fiscal quarter ended April 30, 2014 and our
financial statements and related notes thereto, which are incorporated by reference into the Preliminary Offering Memorandum.

	(1)	In accordance with ASC 470-20, convertible debt that may be wholly or partially settled in cash is required to be separated into a liability and an equity component, such that interest expense reflects the issuer’s
non-convertible debt interest rate. Upon issuance, a debt discount is recognized as a decrease in debt and an increase in equity. The debt component will accrete up to the principal amount ($500.0 million for the notes offered hereby) over the
expected term of the debt. ASC 470-20 does not affect the actual amount that we are required to repay, and the amount shown in the table above for the notes is the aggregate principal amount of the notes and does not reflect the debt discount that
we will be required to recognize in our consolidated balance sheet. 


	(2)	The number of shares of common stock issued and outstanding is based on the number of shares outstanding as of April 30, 2014, which includes 1,556,925 shares of common stock issued to certain former shareholders
of Cyvera Ltd. and excludes: 

  

	 	•	 	approximately 6,596,000 shares of common stock issuable upon the exercise of outstanding options to purchase our common stock at April 30, 2014 at a weighted average exercise price of $12.88 per share;


  

	 	•	 	approximately 5,310,000 shares of common stock issuable upon the vesting of outstanding restricted stock units as of April 30, 2014; 


 

	 	•	 	approximately 8,955,000 shares of common stock reserved for future issuance under our equity compensation plans at April 30, 2014; 


 

	 	•	 	1,080,747 shares of common stock and 463,177 shares of common stock issuable upon the exercise of a warrant at an exercise price of $0.0001 per share, issued to Juniper Networks, Inc. in May 2014 and June 2014,
respectively; and 









	 	•	 	the shares of common stock reserved for issuance upon conversion of the notes offered hereby and upon exercise of the warrants to be sold pursuant to the warrant transactions described in the offering memorandum.


  

	(3)	Issuance of the notes (giving effect to the application of ASC 470-20 to the notes as described in note (1) above) and the entry into the convertible note hedge and warrant transactions will result in a net
increase in additional paid-in capital and, therefore, a net increase in total stockholders’ equity and total capitalization. The amounts shown in the above table do not reflect these increases.

Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. 

The restrictions described in the prior sentence shall not apply to: 
  


	 	(a)	the transfer of shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (i) to the spouse, domestic partner, parent, sibling, child or grandchild (each, an

	 	(e)	the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock

of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the 90-day period referred to herein; 


 

	 	(f)	transfers of shares of Common Stock pursuant to any trading plan pursuant to Rule 10b5-1 under the Exchange Act in effect on the date hereof, provided that any filing under Section 16 of the Exchange Act

 48 








 In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the
registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement. 

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All
authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.
