2012 Employee Stock Purchase Plan, as amended and restated, and related form agreements

1.    Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Companies with an opportunity to purchase Common Stock through accumulated Contributions. The Company intends for the Plan to have two components: a Code Section 423 Component (“423 Component”) and a Non-Code Section 423 Component (“Non-423 Component”). The Company’s intention is to have the 423 Component of the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code. The provisions of the 423 Component, accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes the grant of an option to purchase shares of Common Stock under the Non-423 Component that does not qualify as an “employee stock purchase plan” under Section 423 of the Code; such an option will be granted pursuant to rules, procedures or subplans adopted by the Administrator designed to achieve tax, securities laws or other objectives for Eligible Employees and the Company. Except as otherwise provided herein, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

2.    Definitions.

(a)    “Administrator” means the Board or any Committee designated by the Board to administer the Plan pursuant to Section 14.

(b)    “Affiliate” means any entity, other than a Subsidiary, in which the Company has an equity or other ownership interest.

(c)    “Applicable Laws” means the requirements relating to the administration of equity-based awards under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any foreign country or jurisdiction where options are, or will be, granted under the Plan.

(d)    “Board” means the Board of Directors of the Company.

(e)    “Change in Control” means the occurrence of any of the following events:

(i)    A change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change in Control; or

(ii)    A change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12)-

month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or

(iii)    A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection, the following will not constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3). For purposes of this subsection, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company.

Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final U.S. Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder from time to time.

Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.

(f)    “Code” means the U.S. Internal Revenue Code of 1986, as amended. Reference to a specific section of the Code or U.S. Treasury Regulation thereunder will include such section or regulation, any valid regulation or other official applicable guidance promulgated under such section, and any comparable provision of any future legislation or regulation amending, supplementing or superseding such section or regulation.

(g)    “Committee” means a committee of the Board appointed in accordance with Section 14 hereof.

(h)    “Common Stock” means the common stock of the Company.

(i)    “Company” means Palo Alto Networks, Inc., a Delaware corporation, or any successor thereto.

(j)    “Compensation” means an Eligible Employee’s base straight time gross earnings, payments for overtime and shift premium, but exclusive of payments for commissions, incentive compensation, bonuses and other similar compensation. The Administrator, in its discretion, may, on a uniform and nondiscriminatory basis, establish a different definition of Compensation for a subsequent Offering Period.

(k)    “Contributions” means the payroll deductions and other additional payments that the Company may permit to be made by a Participant to fund the exercise of options granted pursuant to the Plan.

(l)    “Designated Company” means any Subsidiary or Affiliate that has been designated by the Administrator from time to time in its sole discretion as eligible to participate in the Plan. For purposes of the 423 Component, only the Company and its Subsidiaries may be Designated Companies, provided, however, that at any given time, a Subsidiary that is a Designated Company under the 423 Component shall not be a Designated Company under the Non-423 Component.

(m)    “Director” means a member of the Board.

(n)    “Eligible Employee” means any individual who is providing services to the Company or a Designated Company as an employee and is considered by the Company or a Designated Company to be an employee and who meets any minimum service limitations determined under the methodology specified below. For purposes of clarity, the term “Eligible Employee” shall not include the following, regardless of any subsequent reclassification as an employee by the Company or a Designated Company, any governmental agency, or any court: (i) any independent contractor; (ii) any consultant; (iii) any individual performing services for the Company or a Designated Company who has entered into an independent contractor or consultant agreement with the Company or a Designated Company; (iv) any individual performing services for the Company or a Designated Company under a purchase order, a supplier agreement or any other agreement that the Company or a Designated Company enters into for services; (v) any individual classified by the Company or a Designated Company as contract labor (such as contractors, contract employees, job shoppers), regardless of length of service; (vi) any individual whose base wage or salary is not processed for payment by the payroll department(s) or payroll provider(s) of the Company or a Designated Company; and (vii) any leased employee within the meaning of Code Section 414(n), including such persons leased from a professional employer organization. The exclusive means for individuals who are not contemporaneously classified as employees of the Company or a Designated Company on the Company’s or Designated Company’s payroll system on an Enrollment Date to become eligible to participate in the Plan is through the adoption of a subplan that specifically designates such individuals eligible to participate.

For purposes of the Plan, the employment relationship will be treated as continuing intact while the individual is on sick leave or other leave of absence that the Employer approves or is legally protected under Applicable Laws. Where the period of leave exceeds three (3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have terminated three (3) months and one (1) day following the commencement of such leave. 

The Administrator retains the authority to revise the definition of Eligible Employee (on a uniform and nondiscriminatory basis or as otherwise permitted by Treasury Regulation Section 1.423-2). Accordingly, the Administrator, in its discretion, from time to time may, prior to an Enrollment Date for all options to be granted on such Enrollment Date in an Offering, determine (on a uniform and nondiscriminatory basis or as otherwise permitted by Treasury Regulation Section 1.423-2) that the definition of Eligible Employee will or will not include an individual if he or she: (i) has not completed at least two (2) years of service since his or her last hire date (or such lesser period of time as may be determined by the Administrator in its discretion), (ii) customarily works not more than twenty (20) hours per week (or such lesser period of time as may be determined by the Administrator in its discretion), (iii) customarily works not more than five (5) months per calendar year (or such lesser period of time as may be determined by the Administrator in its discretion), (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code, or (v) is a highly compensated employee within the meaning of Section 414(q) of the Code with compensation above a certain level or is an officer or subject to the disclosure requirements of Section 16(a) of the Exchange Act, provided the exclusion is applied with respect to each Offering in an identical manner to all highly compensated individuals of the Employer whose Employees are participating in that Offering. Until subsequent action is taken by the Administrator, to be an Eligible Employee an individual must be customarily employed for at least twenty (20) hours per week and more than five (5) months in any calendar year by the Employer, or any lesser number of hours per week and/or number of months in any calendar year established by the Administrator (if required under applicable local law) for purposes of any separate Offering or for Eligible Employees participating in the Non-423 Component. Each exclusion shall be applied with respect to an Offering in a manner complying with U.S. Treasury Regulation Section 1.423-2(e)(2)(ii).”

(ii)    If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, its Fair Market Value will be the mean between the high bid and low asked prices for the Common Stock on the date of

determination (or if no bids and asks were reported on that date, as applicable, on the last Trading Day such bids and asks were reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or

(iii)    In the absence of an established market for the Common Stock, the Fair Market Value thereof will be determined in good faith by the Administrator.

(u)    “New Exercise Date” means a new Exercise Date if the Administrator shortens any Offering Period then in progress.

(v)    “Offering” means an offer under the Plan of an option that may be exercised during an Offering Period as further described in Section 4. For purposes of the Plan, the Administrator may designate separate Offerings under the Plan (the terms of which need not be identical) in which Employees of one or more Employers will participate, even if the dates of the applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by U.S. Treasury Regulation Section 1.423-2(a)(1), the terms of each Offering need not be identical provided that the terms of the Plan and an Offering together satisfy U.S. Treasury Regulation Section 1.423-2(a)(2) and (a)(3).

3.    Eligibility.

(a)    Enrollment. Any Eligible Employee on a given Enrollment Date subsequent to the first Offering Period will be eligible to participate in the Plan, subject to the requirements of Section 5.

(b)    Non-U.S. Employees. Eligible Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether they also are citizens or residents of the United States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from participation in the Plan or an Offering if the participation of such Eligible Employees is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to violate Section 423 of the Code. In the case of the Non-423 Component, Eligible Employees may be excluded from participation in the Plan or an Offering if the Administrator has determined that participation of such Eligible Employees is not advisable or practicable.

(c)    Limitations. Any provisions of the Plan to the contrary notwithstanding, no Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds twenty-five thousand dollars ($25,000) worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time, as determined in accordance with Section 423 of the Code and the regulations thereunder.

4.    Offering Periods. The Plan will be implemented by overlapping Offering Periods with a new Offering Period commencing on the first Trading Day on or after February 28 and August 31 of each year, or on such other date as the Administrator will determine. Notwithstanding the foregoing, the first Offering Period following the Restatement Effective Date will commence on September 18, 2017. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future Offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter; provided, however, that no Offering Period may last more than twenty-seven (27) months.

5.    Participation. An Eligible Employee may participate in the Plan pursuant to Section 3(a) by (i) submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable Enrollment Date, a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose, or (ii) following an electronic or other enrollment procedure determined by the Administrator.

6.    Contributions.

(a)    At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering Period in an amount not exceeding fifteen percent (15%) of the Compensation, which he or she receives on each pay day during the Offering Period, including any pay day that occurs on an Exercise Date. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

(b)    In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10 hereof; provided, however, that for the first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window.

(c)    All Contributions made for a Participant will be credited to his or her account under the Plan and Contributions will be made in whole percentages only. A Participant may not make any additional payments into such account.

(d)    A Participant may discontinue his or her participation in the Plan as provided in Section 10. Unless otherwise determined by the Administrator, during an Offering Period, a Participant may not increase the rate of his or her Contributions and may only decrease the rate of his or her Contributions one (1) time per Purchase Period. Any such decrease during an Offering Period requires the Participant (i) properly completing and submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in Contribution rate in the form provided by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the Administrator. If a Participant has not followed such procedures to change the rate of Contributions, the rate of his or her Contributions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless terminated as provided in Section 10). The Administrator may, in its sole discretion, amend the nature and/or number of Contribution rate changes that may be made by Participants during any Offering Period or Purchase Period, and may establish such other conditions or limitations as it deems appropriate for Plan administration. Any change in payroll deduction rate made pursuant to this Section 6(d) will be effective as of the first full payroll period following five (5) business days after the date on which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in payroll deduction rate more quickly).

(e)    Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(c), a Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(c) hereof, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10.

(f)    Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Eligible Employees to participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code, or (iii) for Participants participating in the Non-423 Component.

(g)    At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

7.    Grant of Option. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than 625 shares of Common Stock (subject to any adjustment pursuant to Section 19) and provided further that such purchase will be subject to the limitations set forth in Sections 3(d) and 13. The Eligible Employee may accept the grant of such option (i) with respect to the first Offering Period by submitting a properly completed subscription agreement in accordance with the requirements of Section 5 on or before the last day of the Enrollment Window, and (ii) with respect to any subsequent Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period of an Offering Period. Exercise of the option will occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period.

8.    Exercise of Option.

(a)    Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be promptly refunded to Participant as soon as reasonably practicable following an Exercise Date. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her.

(b)    If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date.

9.    Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided in this Section 9.

10.    Withdrawal.

(a)    A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or her option under the Plan at least one (1) business day prior to an Exercise Date by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure determined by the Administrator. All of the Participant’s

Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5.

(b)    A Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws.

11.    Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such Participant’s option will be automatically terminated.

12.    Interest. No interest will accrue on the Contributions of a participant in the Plan, except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f).

13.    Stock.

(a)    Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of Common Stock that will be made available for sale under the Plan will be 1,000,000 shares of Common Stock, plus an annual increase to be added on the first day of each Fiscal Year beginning with the 2014 Fiscal Year equal to the least of (i) 2,000,000 shares of Common Stock, (ii) one percent (1%) of the outstanding shares of Common Stock on such date, or (iii) an amount determined by the Administrator.

(b)    Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

(c)    Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and his or her spouse.

14.    Administration. The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to designate separate Offerings under the Plan, to designate Subsidiaries and Affiliates as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including, without limitation, to adopt such procedures and sub-plans as are necessary or

appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans may take precedence over other provisions of this Plan, with the exception of Section 13(a) hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan). Unless otherwise determined by the Administrator, the Employees eligible to participate in each sub-plan will participate in a separate Offering or in the Non-423 Component. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.

15.    Designation of Beneficiary.

(a)    If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any shares of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

(b)    Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Administrator, which may be electronic. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

(c)    All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

16.    Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15

hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

17.    Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party. Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to such shares.

18.    Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

19.    Adjustments, Dissolution, Liquidation, Merger or Change in Control.

(a)    Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13.

(b)    Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

(c)    Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

20.    Amendment or Termination.

(a)    The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12 hereof) as soon as administratively practicable.

(b)    Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change the Offering Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit Contributions in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with the Plan.

(c)    In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:

(i)    amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;

(ii)    altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the time of the change in Purchase Price;

(iii)    shortening any Offering Period or Purchase Period by setting a New Exercise Date, including an Offering Period or Purchase Period underway at the time of the Administrator action;

(iv)    reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and

(v)    reducing the maximum number of Shares a Participant may purchase during any Offering Period or Purchase Period.

Such modifications or amendments will not require stockholder approval or the consent of any Plan Participants.

21.    Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

22.    Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

23.    Code Section 409A. The 423 Component of the Plan is exempt from the application of Code Section 409A and any ambiguities herein will be interpreted to so be exempt from Code Section 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Code Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Code Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. Notwithstanding the foregoing, the Company shall have no liability to a Participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Code Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under the Plan is compliant with Code Section 409A.

24.    Term of Plan. The Plan will become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It will continue in effect for a term of twenty (20) years, unless sooner terminated under Section 20.

25.    Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

26.    Governing Law. The Plan shall be governed by, and construed in accordance with, the laws of the State of California (except its choice-of-law provisions).

27.    No Right to Employment. Participation in the Plan by a Participant shall not be construed as giving a Participant the right to be retained as an employee of the Company or a Subsidiary or Affiliate, as applicable. Furthermore, the Company or a Subsidiary or Affiliate may dismiss a Participant from employment at any time, free from any liability or any claim under the Plan.

28.    Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

29.    Compliance with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed accordingly.

30.    Automatic Transfer to Low Price Offering Period. To the extent permitted by Applicable Laws, if the Fair Market Value of the Common Stock on any Exercise Date in an Offering Period is lower than the Fair Market Value of the Common Stock on the Enrollment Date of such Offering Period, then all participants in such Offering Period will be automatically withdrawn from such Offering Period immediately after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period as of the first day thereof.

Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider-trading policy. I am responsible for complying with any applicable restrictions, and I should speak to my personal legal advisor for further details regarding any applicable insider-trading and/or market-abuse laws in my country.

Exchange Control, Foreign Asset/Account and/or Tax Reporting. I acknowledge that certain foreign asset and/or account reporting requirements which may affect my ability to acquire or hold shares of Common Stock under the ESPP or cash received from participating in the ESPP (including from any dividends received or sale proceeds arising from the sale of shares of Common Stock) in a brokerage or bank account outside my country. I also may be required to repatriate sale proceeds or other funds received as a result of my participation in the ESPP to my country through a designated bank or broker and/or within a certain time after receipt. In addition, I may be subject to tax payment and/or reporting obligations in connection with any income realized under the ESPP and/or from the sale of shares of Common Stock.

By clicking “ACCEPT” and electronically enrolling in the ESPP, I hereby agree to be bound by the terms of the ESPP and this Agreement. The effectiveness of this Agreement is dependent upon my eligibility to participate in the ESPP. I have received a copy of the complete ESPP and its accompanying prospectus. I understand that my participation in the ESPP is in all respects subject to the terms of the ESPP. Further, I expressly acknowledge the information provided in the Appendix related to the collection, processing and use of my personal data by the Company and its Subsidiaries or Affiliates and the transfer of personal data to the recipients mentioned in the Appendix.

I UNDERSTAND THAT THIS AGREEMENT WILL REMAIN IN EFFECT THROUGHOUT SUCCESSIVE OFFERING PERIODS UNLESS TERMINATED BY ME.

Certain capitalized terms used but not defined in this Appendix have the meanings set forth in the ESPP and/or the Global Subscription Agreement.

This Appendix includes additional terms and conditions that govern my participation in the ESPP, including the option to purchase shares of Common Stock granted under the ESPP, if I reside and/or work in one of the countries listed below.

If I am a citizen or resident (or am considered as such for local law purposes) of a country other than the one in which I am currently residing and/or working or if I transfer employment and/or residency to another country after enrolling in the ESPP, the terms and conditions of participation in the ESPP contained herein may not be applicable to me and the Company shall, in its discretion, determine to what extent the terms and conditions contained herein shall apply to my participation in the ESPP.

This Appendix also includes information regarding exchange controls and certain other issues of which I should be aware with respect to participation in the ESPP. The information is based on the securities, exchange control and other laws in effect in the respective countries as of August 2022. Such laws are often complex and change frequently. As a result, the Company strongly recommends that I not rely on the information herein as my only source of information relating to the consequences of my participation in the ESPP because the information may be out of date at the time that I purchase shares of Common Stock under the ESPP or sell the shares of Common Stock acquired under the ESPP.

In addition, the information contained herein is general in nature and may not apply to my particular situation, and the Company is not in a position to assure me of a particular result. Accordingly, I should seek appropriate professional advice as to how the relevant laws in my country may apply to my situation.

Finally, if I am a citizen or resident (or am considered as such for local law purposes) of a country other than the one in which I am currently residing and/or working or if I transfer employment and/or residency to another country after enrolling in the ESPP, the information contained herein may not be applicable to me.

Australian Offer Document. The Company is providing me with an offer to participate in the ESPP. This offer sets out information regarding the ESPP to Australian resident employees. This information is provided by the Company to ensure compliance of the ESPP with Australian Securities and Investments Commission (“ASIC”) Class Order 14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information set out in the Agreement (including this Appendix), I am also being provided with copies of the following documents:

The Additional Documents provide further information to help me make an informed investment decision about participating in the ESPP. Neither the ESPP nor the ESPP prospectus is a prospectus for the purposes of the Corporations Act 2001.

I should not rely upon any oral statements made in relation to this offer. I should rely only upon the statements contained in the Agreement (including this Appendix) and the Additional Documents when considering participation in the ESPP.

Exchange Control Information. Exchange control reporting is required for cash transactions exceeding AUD10,000 and international fund transfers. I understand that the Australian bank assisting with the transaction may file the report for me. If there is no Australian bank involved in the transfer, I will have to file the report. I acknowledge that I should consult with a personal advisor to ensure that I am properly complying with applicable reporting requirements in Australia.

Securities Law Information. Investment in Common Stock involves a degree of risk. Eligible employees who elect to participate in the Plan should monitor their participation and consider all risk factors relevant to the acquisition of Common Stock under the ESPP as set forth below and in the Additional Documents.

Additional Risk Factors for Australian Residents. I should have regard to risk factors relevant to investment in securities generally and, in particular, to holding shares of Common Stock. For example, the price at which an individual share of Common Stock is quoted on The Nasdaq Global Select Market (“Nasdaq”) may increase or decrease due to a number of factors. There is no guarantee that the price of a share of Common Stock will increase. Factors that may affect the price of the Common Stock include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company operates and general operational and business risks.

More information about potential factors that could affect the Company’s business and financial results will be included in the Company’s most recent Annual Report on Form 10-K and the Company’s Quarterly Report on Form 10-Q. Copies of these reports are available at www.sec.gov, on the Company’s investor’s page at https://investors.paloaltonetworks.com/investor-relations/financials/sec-filings/default.aspx, and upon request to the Company.

In addition, Participant should be aware that the Australian dollar (“AUD”) value of any shares of Common Stock acquired under the ESPP will be affected by the USD/AUD exchange rate. Participation in the ESPP involves certain risks related to fluctuations in this rate of exchange.

Common Stock in a U.S. Corporation. Common stock of a U.S. corporation is analogous to ordinary shares of an Australian corporation. Each holder of a share of Common Stock is entitled to one vote. Dividends may be paid on the shares of Common Stock out of any funds of the Company legally available for dividends at the discretion of the Board. Further, the Common Stock is not liable to any further calls for payment of capital or for other assessment by the Company and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption provisions.

Ascertaining the Market Price of Shares. I may ascertain the current market price of the Common Stock as traded on The Nasdaq Global Select Market under the symbol “PANW” at https://www.nasdaq.com/market-activity/stocks/panw. The AUD equivalent of that price can be obtained at www.rba.gov.au/statistics/frequency/exchange-rates.html. Please note that this is not a prediction of what the market price of the Common Stock will be on any applicable Exercise Date or when shares of Common Stock are issued to me (or at any other time), or of the applicable exchange rate at such time.

Interest Waiver. By enrolling in the ESPP and accepting the terms of the Agreement, I unambiguously consent to waive my right to any interest with respect to payroll deductions accumulated for me during an Offering Period.

Amount of Contribution. My individual payroll deductions are subject to compliance with the minimum salary and minimum subsistence level provisions under Applicable Laws in Austria. The Company and/or the Employer, at their discretion, may limit the amount of my payroll deductions to comply with such requirements.

Exchange Control Information. If I hold securities (including shares of Common Stock acquired under the ESPP outside Austria, even if I hold them outside of Austria with an Austrian bank) or cash (including proceeds from the sales of shares of Common Stock), I understand I must submit an annual report to the Austrian National Bank using the form “Standmeldung/Wertpapiere.” An exemption applies if the value of the shares held outside Austria of any quarter does not exceed

€5,000,000. The deadline for filing the quarterly report is the 15th of the month following the end of the respective quarter.

If I sell shares of Common Stock or receive any cash dividends, there may be exchange control obligations if the cash received is held outside Austria, as a separate reporting requirement applies to any non-Austrian cash accounts. If the transaction volume of all of my cash accounts abroad exceeds €10,000,000, the movements and the balance of all accounts must be reported monthly, as of the last day of the month, on or before the 15th day of the following month, using the form “Meldungen SI-Forderungen und/oder SI-Verpflichtungen.”

Authorization to Remit Eligible Cash Earnings. For Belgian law purposes, I understand that “payroll deductions” means a specific instruction to the Employer to pay out part of my Compensation (as indicated in the Agreement) in order to fund the Purchase Price for the shares of Common Stock, in accordance with the terms and conditions of the ESPP.

Exchange Control Information. I acknowledge and understand that if I am a Belgian resident, I am required to complete a report providing the National Bank of Belgium with details regarding any securities or bank accounts held outside Belgium, including the account number, the name of the bank in which such account is held and the country in which the account is located. This report, as well as information on how to complete it, can be found on the website of the National Bank of Belgium, www.nbb.be, under the Kredietcentrales / Centrales des credits caption.

Authorization for Transmission of Funds. I agree to execute a letter of authorization and any other agreements or consents that may be required to enable the Company, any Subsidiary or Affiliate or the Employer to remit accumulated payroll deductions from Brazil to the United States for the purchase of shares of Common Stock. I understand that if I fail to execute the letter of authorization or any other agreements or consents that may be required for the remittance of payroll deductions, I will not be able to participate in the ESPP.

Compliance with Law. By enrolling in the ESPP and accepting the terms of this Agreement, I acknowledge and agree to comply with all applicable Brazilian laws and pay any and all applicable taxes associated with the purchase and sale of shares of Common Stock acquired pursuant to the ESPP and the receipt of any dividends paid on such shares.

Nature of Grant. The following provision supplements Section 5 of the Global Subscription Agreement:

By enrolling and participating in the ESPP, I agree that (i) I am making an investment decision and

Exchange Control Information. If I am a resident or domiciled in Brazil, I will be required to submit an annual declaration of assets and rights held outside of Brazil to the Central Bank of Brazil if the aggregate value of such assets and rights is equal to or greater than US$1,000,000.

Quarterly reporting is required if the aggregate value of such assets and rights exceeds US$100,000,000. Assets and rights that must be reported include shares of Common Stock acquired pursuant to the ESPP.

In the event of termination of my employment (for any reason and whether or not later found to be invalid or in breach of Canadian laws or the terms of my employment agreement, if any), my right to participate in the ESPP, if any, shall terminate effective as of the date that is the earlier of (i) the date of my termination or (ii) the date I receive notice of termination. In either case, the date shall exclude any period during which notice, pay in lieu of notice or related payments or damages are provided or required to be provided under local law. For greater certainty, I will not purchase or be entitled to any pro-rated purchase of shares for that portion of time before the date on which my participation terminates, nor will I be entitled to any compensation for lost purchase.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued participation in the ESPP during a statutory notice period, I acknowledge my right to participate in the ESPP, if any, will terminate effective as of the last day of my minimum statutory notice period, but I will not earn or be entitled to any pro-rated purchase of shares if the Exercise Date falls after the end of my statutory notice period, nor will I be entitled to any compensation for the lost purchase of shares.

I hereby authorize the Company and the Company’s representatives to discuss with and obtain all relevant information from all personnel, professional or not, involved in the administration and operation of the ESPP. I further authorize the Company or any Subsidiary or Affiliate and the Administrator to disclose and discuss the ESPP with their advisors. I acknowledge and agree that my personal information, including sensitive personal information, may be transferred or disclosed outside the Province of Quebec, including to the United States. I further authorize the Company or any Subsidiary or Affiliate to record such information and to keep such information in my employee file. I also acknowledge and authorize the Company and other parties involved in the administration of the ESPP to use technology for profiling purposes and to make automated decisions that may have an impact on me or the administration of the ESPP.

Securities Law Information. I acknowledge that I am permitted to sell shares of Common Stock acquired pursuant to the ESPP through the designated broker appointed under the ESPP, if any, provided the sale of the shares acquired pursuant to the ESPP takes place outside of Canada through the facilities of a stock exchange on which the shares are listed (i.e., the Nasdaq Stock Market).

Purchase Conditioned on Satisfaction of Regulatory Obligations. Notwithstanding anything to the contrary in the Agreement or the ESPP, no shares of Common Stock will be purchased on my behalf unless and until all necessary exchange control or other approvals with respect to the ESPP have been obtained from SAFE or its local counterpart (“SAFE Approval”) and maintained prior to each Exercise Date. In the event SAFE Approval has not been obtained or maintained prior to any Exercise Date(s), the Company may return payroll deductions credited to my account but not used to purchase shares during the Purchase Period, without interest, or take such other steps as it determines in its sole discretion to be necessary for the implementation of the ESPP. In such case, participation in the ESPP will continue, unless I otherwise withdraw from or becomes ineligible to participate in the ESPP.

Shares Must Remain With Company’s Designated Broker. I agree to hold any shares of Common Stock acquired under the ESPP with E*TRADE, or such other broker as the Company may designate, until the shares are sold. The limitation shall apply to all shares issued to me under the ESPP, whether or not I remain an Eligible Employee.

Sale of Shares. Due to local regulatory requirements, I understand and agree that the Company may require that any shares of Common Stock purchased under the ESPP be immediately sold.

I further agree that the Company is authorized to instruct its designated broker to assist with the mandatory sale of such shares (on my behalf pursuant to this authorization without further consent) and I expressly authorize the Company’s designated broker to complete the sale of such shares. In this regard, I agree to sign any agreements, forms and/or consents that may be reasonably requested by the Company (or the Company’s designated broker) to effectuate the sale of the shares (including, without limitation, as to the transfers of the proceeds and other exchange control matters noted below) and shall otherwise cooperate with the Company with respect to such matters, provided that I shall not be permitted to exercise any influence over how,

when or whether the sales occur. I acknowledge that the Company’s designated broker is under no obligation to arrange for the sale of the shares at any particular price.

If the Company, in its discretion, does not exercise its right to require the automatic sale of the shares purchased under the ESPP, as described in the preceding paragraph, I understand and agree that any shares acquired under the ESPP must be sold no later than six months from my termination of employment, or within any such other period as may be permitted by the Company or required by SAFE. I understand that any shares acquired under the ESPP that have not been sold within six months of my termination or within such other period as may be permitted by the Company or required by SAFE will be automatically sold by the designated broker pursuant to this authorization without further consent and subject to the terms of the preceding paragraph.

Upon the sale of the shares, I will receive the cash proceeds from the sale, less any brokerage fees or commissions and subject to any obligation to satisfy any Tax-Related Items. I agree to comply with all requirements the Company may impose in order to facilitate compliance with exchange control requirements in China prior to receipt of the cash proceeds. I acknowledge that I am not aware of any material nonpublic information with respect to the Company or any securities of the Company as of the date of the Agreement.

Exchange Control Requirements. By enrolling and participating in the ESPP, I understand and agree that, pursuant to local exchange control requirements, I will be required to repatriate the cash proceeds from the sale of the shares and the receipt of any dividends to China. I further understand that, under local law, such repatriation of the cash proceeds may need to be effectuated through a special exchange control account established by the Company, the Employer or another Subsidiary or Affiliate, and I hereby consent and agree that any proceeds from the sale of any shares I acquire under the ESPP and any dividends may be transferred to such special account prior to being delivered to me.

I further understand that the proceeds will be delivered to me as soon as possible, but there may be delays in distributing the funds to me due to exchange control requirements in China. Proceeds may be paid to me in U.S. dollars or local currency, at the Company’s discretion. If the proceeds are paid in U.S. dollars, I will be required to set up a U.S. dollar bank account in China so that the proceeds may be deposited into this account. If the proceeds are paid in local currency, I agree that the Company, the Employer or any other Subsidiary or Affiliate in China is under no obligation to secure any particular exchange conversion rate and there may be delays in converting the cash proceeds to local currency due to exchange control restrictions. I agree to bear any currency fluctuation risk between the time the cash proceeds are received and the time the cash proceeds are distributed to me through the special account described above.

I further agree to comply with any other requirements that may be imposed by the Company in the future in order to facilitate compliance with exchange control requirements in China.

Additional Restrictions. No shares of Common Stock will be purchased or issued unless the Company determines that such purchase and issuance and delivery of shares complies with all

Applicable Laws. Further, the Company is under no obligation to purchase and/or issue shares if the Company’s SAFE approval becomes invalid or ceases to be in effect by the Exercise Date.

Authorization for Payroll Deductions. I hereby expressly acknowledge that my authorization to the Employer to withhold a percentage of my Compensation, as specified in the Global Subscription Agreement, was given voluntarily for purposes of my participation in the ESPP.

Payroll Deduction Authorization.

I understand I will not be able to participate in the ESPP if I fail to execute the Agreement on Wage Deductions.

Exchange Control Information. The Czech National Bank may require me to fulfill certain notification duties in relation to the purchase of shares of Common Stock under the ESPP and/or the opening and maintenance of a foreign bank or brokerage account. In addition, I may need to report certain events even in the absence of a request from the Czech National Bank. Because exchange control regulations may change without notice, I should consult my personal legal advisor prior to the purchase or the sale of shares of Common Stock to ensure compliance with current regulations. It is my responsibility to comply with any applicable Czech exchange control laws.

Danish Stock Option Act. By accepting the option to purchase shares of Common Stock and enrolling in the ESPP, I acknowledge that I have received the Employer Statement translated into Danish and set forth below, which is being provided to comply with the Danish Stock Option Act (the “Act”).

I acknowledge that the Act has been amended as of January 1, 2019. Accordingly, I agree that in the event of termination of my employment, the provisions governing my participation in the ESPP under this Agreement and the ESPP will apply for any Offering Period which begins on or after January 1, 2019. The relevant provisions are detailed in the Agreement, the ESPP and the Employer Statement.

The form of report (“Allgemeine Meldeportal Statistik”) can be accessed via the Bundesbank’s website (www.bundesbank.de) and is available in both German and English.

Exchange Control Information. I understand that I must repatriate any proceeds from the sale of shares of Common Stock purchased under the ESPP and any dividends received in relation to the shares of Common Stock to India and convert the proceeds into local currency within such period of time as required under applicable regulations). I should obtain a foreign inward remittance certificate (the “FIRC”) from the bank where I deposit the foreign currency and maintain the FIRC as evidence of the repatriation of funds in the event the Reserve Bank of India or the Employer requests proof of repatriation.

As a condition of my participation in the ESPP, I authorize the Company or the Employer to withhold Tax-Related Items arising in Ireland at the time I purchase shares of Common Stock under the ESPP, regardless of the fact that such withholding may not be required by law. I further acknowledge and agree that the Company or the Employer may accomplish such withholding by any one or a combination of the methods described in Section 4 of the Global Subscription Agreement. Notwithstanding this provision, I acknowledge and agree that, should the Company or the Employer fail to withhold Tax-Related Items for any or no reason, it remains my obligation to satisfy all Tax- Related Items and neither the Company nor the Employee will be liable for my failure to satisfy such obligations.

This notification requirement also applies with respect to the interests of the spouse or children under the age of 18 of the director, shadow director or secretary (whose interests will be attributed to the director, shadow director or secretary).

Acknowledgement of the Agreement. By enrolling and participating in the ESPP, I acknowledge that I have received a copy of the ESPP and the Agreement, including this Appendix, which I have reviewed. I further acknowledge that I accept all the provisions of the ESPP and the Agreement, including this Appendix. I also acknowledge that I have read and specifically and expressly approves the terms and conditions set forth in Section 5 of the Global Subscription Agreement, which clearly provide as follows:

Labor Law Policy and Acknowledgment. I expressly recognize that the Company, with registered offices at 3000 Tannery Way, Santa Clara, California 95054, USA, is solely responsible for the

administration of the ESPP and that my participation in the ESPP and purchase of shares of Common Stock does not constitute an employment relationship between myself and the Company since I am participating in the ESPP on a wholly commercial basis. Based on the foregoing, I expressly recognize that the ESPP and the benefits that I may derive from participation in the ESPP do not establish any rights between myself and the Employer and do not form part of the employment conditions and/or benefits provided by the Employer and any modification of the ESPP or its termination shall not constitute a change or impairment of the terms and conditions of my employment.

I further understand that my participation in the ESPP is as a result of a unilateral and discretionary decision of the Company, therefore, the Company reserves the absolute right to amend and/or discontinue my participation at any time without any liability to me.

Finally, I hereby declare that I do not reserve any action or right to bring any claim against the Company for any compensation or damages regarding any provision of the ESPP or the benefits derived under the ESPP, and I therefore grant a full and broad release to the Company, its branches, representation offices, shareholders, officers, agents or legal representatives and any Subsidiary or Affiliate with respect to any claim that may arise.

Securities Law Information. The option to purchase shares of Common Stock and any shares of Common Stock acquired under the ESPP have not been registered with the National Register of Securities maintained by the Mexican National Banking and Securities Commission and cannot be offered or sold publicly in Mexico. In addition, the ESPP, the Agreement and any other document relating to the option to purchase shares of Common Stock may not be publicly distributed in Mexico. I acknowledge that these materials are addressed to me because of my existing relationship with the Company and these materials should not be reproduced or copied in any form. The offer contained in these materials does not constitute a public offering of securities, but rather constitutes a private placement of securities addressed specifically to Eligible Employees made in accordance with the provisions of the Mexican Securities Market Law, and any rights under such offering shall not be assigned or transferred.

Polish residents holding foreign securities (including shares of Common Stock) and maintaining accounts abroad must report information to the National Bank of Poland on transactions and balances of the securities and cash deposited in such accounts if the value of such transactions or balances exceeds PLN 7,000,000. If required, the reports must be filed on a quarterly basis on special forms available on the website of the National Bank of Poland. In addition, transfers of funds in excess of €15,000 into and out of Poland must be made via a bank account held at a bank in Poland. Polish residents are required to store all documents related to any foreign exchange transactions for a period of five years. I understand that I am responsible for complying with all applicable exchange control regulations.

Language Consent. I hereby agree to receive information related to the ESPP in English through my participation in the ESPP. Specifically, I acknowledge as follows:

I hereby expressly declare that I have full knowledge of the English language and have read, understood and fully accepted and agreed with the terms and conditions established in the ESPP and the Agreement.

Exchange Control Information. If I hold shares of Common Stock acquired under the ESPP, the acquisition of shares should be reported to the Banco de Portugal for statistical purposes. If the shares are deposited with a commercial bank or financial intermediary in Portugal, such bank or financial intermediary will submit the report on my behalf. If the shares are not deposited with a commercial bank or financial intermediary in Portugal, I am responsible for submitting the report to the Banco de Portugal.

Securities Law Information. The options granted under the ESPP and any shares of Common Stock issued under the ESPP have not been offered, sold or delivered and will not be offered, sold or delivered, at any time, directly or indirectly in the State of Qatar in a manner that would constitute a public offering.

The Agreement, the ESPP and any other incidental communication materials distributed in connection with the ESPP have not been, and will not be, registered with or approved by the Qatar Financial Markets Authority or Qatar Central Bank and may not be publicly distributed. The Agreement, the ESPP and any other incidental communication materials distributed in connection with the ESPP are intended only for Eligible Employees and must not be provided to any other person. These materials are not for general circulation in the State of Qatar and may not be reproduced or used for any other purpose.

Language Consent. By participating in the ESPP, I acknowledge that I am proficient in reading and understanding English and fully understand the terms of the documents related to my participation (the ESPP and the Agreement), which were provided in the English language. I accept the terms of those documents accordingly.

Exchange Control Information. If I deposit the proceeds from the sale of shares of Common Stock acquired under the ESPP into a bank account in Romania, I may be required to provide the Romanian bank with appropriate documentation explaining the source of the funds. I understand that I should consult with my personal legal advisor to determine whether I will be required to submit such documentation to the Romanian bank.

Authorization for ESPP Participation. I agree to act in accordance with any procedures established by the Company to comply with the exchange control regulations in Russia and to provide a power of attorney (if I have not already done so) or any other agreements or consents that may be required by the Company to facilitate my participation in the ESPP. I understand that if I fail to comply with required procedures or to execute a power of attorney or any other required agreement or consent, I will not be able to participate in the ESPP.

U.S. Transaction. I understand that acceptance of the Agreement results in a contract between me and the Company completed in the United States and that the Agreement is governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. I understand that, upon purchase of shares of Common Stock under the ESPP, any such shares of Common Stock shall be held in the United States and in no event will such shares of Common Stock be delivered to me in Russia. I acknowledge that I am not permitted to sell or otherwise transfer shares of Common Stock directly to other individuals in Russia, nor am I permitted to bring any certificates representing the shares of Common Stock into Russia (if such certificates are actually issued).

Securities Law Information. The option to purchase shares of Common Stock, the Agreement, the ESPP and all other materials I may receive regarding my participation in the ESPP do not constitute advertising or an offering of securities in Russia. The issuance of shares of Common Stock under the ESPP has not and will not be registered in Russia and, therefore, the shares of Common Stock purchased by me under the ESPP may not be offered or placed in public circulation in Russia.

Exchange Control Information. I understand that I am responsible for complying with any and all Russian foreign exchange requirements in connection with the ESPP, any shares of Common Stock acquired under the ESPP and funds remitted into Russia in connection with ESPP. This may include, in certain circumstances, reporting and repatriation requirements. Because the exchange control regulations change frequently and without notice, I should consult with a legal advisor to ensure compliance with any exchange control regulations applicable to any aspect of my participation in the ESPP.

Foreign Asset/Account Reporting Information. Russian residents are required to report the opening, closing or change in account details of any foreign bank account to the Russian tax authorities within one month of the opening, closing or change of such account. Russian residents also are required to report to the Russian tax authorities on or before June 1 of the following year (i) the beginning and ending balances in a foreign bank account each year and (ii) transactions related to such a foreign account during the year. Foreign brokerage accounts and foreign accounts with other financial institutions (financial market organizations) also must be reported. Certain specific exceptions from the reporting requirements may apply. Non-compliance with these reporting obligations could impact my ability to receive shares of Common Stock and participate in the ESPP. I should consult with my personal legal advisor to determine how these reporting requirements apply to any account opened in connection with my participation in the ESPP.

Anti-Corruption Information. Anti-corruption laws prohibit certain public servants, their spouses and their dependent children from owning any foreign source financial instruments (e.g., shares of Common Stock of foreign companies such as the Company). I understand that I should inform the Company if I am covered by these laws because I should not hold shares of Common Stock under the ESPP.

Purchase of Shares. I understand that no shares of Common Stock will be purchased on my behalf under the ESPP, provided the Company, in its sole discretion, determines that such purchase does not comply with securities law requirements in Saudi Arabia.

Securities Law Information. The Agreement and related ESPP plan document may not be distributed in Saudi Arabia except to such persons as are permitted under the Offers of Securities and Continuous Obligations issued by the Capital Market Authority.

The Capital Market Authority does not make any representation as to the accuracy or completeness of the Agreement, and expressly disclaims any liability whatsoever for any loss arising from, or incurred in reliance upon, any part of the Agreement. I should conduct my own due diligence on the accuracy of the information relating to the shares of Common Stock. If I do not understand the contents of the Agreement, I should consult an authorized financial advisor.

Restriction on Sale and Transferability of Shares. I understand and acknowledge that my option to purchase shares of Common Stock is subject to section 257 of the Singapore Securities and Futures Act (Chapter 289, 2006 Ed.) (“SFA”) and I will not be able to make any subsequent sale of shares of Common Stock in Singapore, or any offer of the shares of Common Stock acquired under the ESPP unless such sale or offer in Singapore is made (i) more than six months from the date of offer, (ii) pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA, or (iii) pursuant to, and in accordance with the condition of, any other applicable provisions of the SFA.

Securities Law Information. I understand that the option to purchase shares of Common Stock under the ESPP is being granted to me pursuant to the “Qualifying Person” exemption under section 273(1)(f) of the SFA. I further understand that the ESPP has not been lodged or registered as a prospectus with the Monetary Authority of Singapore.

Director Reporting Notice. If I am a director, associate director or shadow director of a Singapore Subsidiary or Affiliate, as such terms are used in the Singapore Companies Act (the “SCA”), I agree to comply with notification requirements under the SCA. Among these requirements is an obligation to notify the Singapore Subsidiary or Affiliate in writing when I receive an interest (e.g., shares of Common Stock) in the Company or any related companies (including when I sell shares acquired under the ESPP). In addition, I must notify the Singapore

Subsidiary or Affiliate when I sell or receive shares of the Company or any related company (including when I sell or receive shares under the ESPP). These notifications must be made within two business days of acquiring or disposing of any interest in the Company or any related company. In addition, I acknowledge that a notification must be made of my interests in the Company or any related company within two business days of becoming a director.

There are no country-specific provisions.

Language Consent. By enrolling in the ESPP, I acknowledge that I am proficient in reading and understanding English and fully understand the terms of the documents related to the grant (the Agreement and the ESPP), which were provided in the English language. I accept the terms of those documents accordingly.

Responsibility for Taxes. The following provision supplements Section 4 of the Global Subscription Agreement:

By enrolling and participating in the ESPP, I agree that, immediately upon the purchase of shares of Common Stock, I will notify the Employer of the amount of any discount/gain realized. I understand that if I fail to advise the Employer of the gain realized upon purchase, I may be liable for a fine. I acknowledge that I am solely responsible for paying any difference between the actual tax liability and the amount withheld.

Tax Clearance Certificate for ESPP Participation. I understand that in order to participate in the ESPP, I may be required to obtain and provide to the Employer, or any third party designated by the Employer or the Company, a Tax Clearance Certificate (with respect to foreign investments – see Exchange Control Information below) bearing the official stamp and signature of the Exchange Control Department of the South African Revenue Service (“SARS”) and I must renew this Tax Clearance Certificate each year or such other period as may be required by the SARS. I acknowledge that my failure to provide a valid Tax Clearance Certificate by the deadline provided by the Employer or the Company may result in my withdrawal from participation in the ESPP.

Securities Law Information. The documents listed below are available for my review on the Company’s website at https://investors.paloaltonetworks.com and the Company’s intranet:

A copy of the above documents will be sent to me free of charge on written request to stockadmin@paloaltonetworks.com.

I should carefully read the materials provided before making a decision whether to participate in the ESPP. In addition, I should contact my tax advisor for specific information concerning my personal tax situation with regard to ESPP participation.

Exchange Control Information. Under current South African exchange control policy, South African residents may invest a maximum of ZAR 11 million per annum in offshore investments, including in shares of Common Stock. The ZAR 11 million allowance consists of a ZAR 1 million annual discretionary allowance which may be utilized for investment and non-investment purposes and without prior authorization, and a ZAR 10 million annual allowance which may be utilized solely for investment purposes and requires a tax clearance certificate. These limits do not apply to non-resident Participants.

It is my responsibility to ensure that I do not exceed the combined limit. This limit is a cumulative allowance; therefore, my ability to remit funds for the purchase of Common Stock will be reduced if my foreign investment limit is utilized to make a transfer of funds offshore that is unrelated to the ESPP. If the ZAR 11 million limit will be exceeded as a result of a purchase under the ESPP, I may still participate in the ESPP; however, I will need to immediately sell the shares of Common Stock purchased on my behalf under the ESPP and repatriate the proceeds to South Africa in order to ensure that I do not hold assets outside South Africa with a value in excess of the permitted offshore investment allowance amount.

As the investment limit and other exchange control requirements are subject to change without notice, I should consult my personal legal advisor prior to the purchase or sale of shares of Common Stock under the ESPP to ensure compliance with current regulations. I am solely responsible for complying with exchange control requirements in South Africa and neither the Company nor any Subsidiary or Affiliate will be liable for any fines or penalties resulting from my failure to do so.

Nature of Grant. This provision supplements Section 5 of the Global Subscription Agreement:

By enrolling in the ESPP, I consent to participation in the ESPP and acknowledge that I have received a copy of the ESPP.

I understand and agree that I will cease to be a Participant in the ESPP upon the termination of my status as an Eligible Employee for any reason (including for the reasons listed below) and my payroll deductions shall cease and be returned to me, without interest, as soon as administratively possible.

In particular, I understand and agree that I will no longer be able to participate in the ESPP and any right to the shares of Common Stock will be forfeited upon the termination of my status as an Eligible Employee due to, but not limited to: resignation, retirement, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause, individual or collective layoff on objective grounds, whether adjudged to be with cause or adjudged or recognized to be without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, unilateral withdrawal by the Employer, and under Article 10.3 of Royal Decree 1382/1985.

Furthermore, I understand that the Company has unilaterally, gratuitously and discretionally decided to grant options to purchase shares of Common Stock under the ESPP to individuals who may be Eligible Employees. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any Subsidiary or Affiliate on an ongoing basis. Consequently, I understand that the option to purchase shares of Common Stock is granted on the assumption and condition that the option and any shares of Common Stock purchased under the ESPP are not part of any employment contract either with the Company or any Subsidiary or Affiliate and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever. In addition, I understand that the option to purchase shares of Common Stock would not be granted to me but for the assumptions and conditions referred to herein; thus, I acknowledge and freely accept that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then the grant of the option to purchase shares of Common Stock shall be null and void.

Securities Law Information. No “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory in connection with the ESPP or the shares of Common Stock acquired pursuant thereto. The Agreement (including this Appendix) has not been nor will it be registered with the Comisión Nacional del Mercado de Valores, and does not constitute a public offering prospectus.

Exchange Control Information. When receiving foreign currency payments exceeding €50,000 derived from the ownership of any shares of Common Stock (i.e., dividends or sale proceeds), I acknowledge that I must inform the financial institution receiving the payment of the basis upon

which such payment is made. I will need to provide the institution with the following information:

(i) my name, address, and tax identification number; (ii) the name and corporate domicile of the Company; (iii) the amount of the payment and the currency used; (iv) the country of origin; (v) the reasons for the payment; and (vi) further information that may be required.

Further, I am required to declare electronically to the Bank of Spain any securities accounts (including brokerage accounts held abroad), as well as the shares held in such accounts, and any transactions carried out with non-residents, if the value of the transactions for all such accounts during the prior tax year or the balances in such accounts as of December 31 of the prior tax year exceed €1,000,000.

Responsibility for Taxes: The following provisions supplement Section 4 of the Global Subscription Agreement:

Without limiting the Company and the Employer’s authority to satisfy their withholding obligations for Tax-Related Items as set forth in Section 4 of the Global Subscription Agreement, by participating in the ESPP, I authorize the Company and/or the Employer to withhold or to sell shares of Common Stock otherwise deliverable to me upon purchase in order to satisfy Tax-Related Items, regardless of whether the Company and/or the Employer has an obligation to withhold such Tax- Related Items.

Securities Law Information. Neither this document nor any other materials relating to participation in the ESPP (i) constitutes a prospectus according to articles 35 et seq. of the Swiss Federal Act on Financial Services (“FinSA”), (ii) may be publicly distributed or otherwise made publicly available in Switzerland to any person other than an Eligible Employee, or (iii) has been or will be filed with, approved or supervised by any Swiss reviewing body according to article 51 FinSA or any Swiss regulatory authority, including the Swiss Financial Market Supervisory Authority.

Data Privacy. I hereby acknowledge that I have read and understand the terms regarding the collection, processing and transfer of Data contained in the Data Privacy Provisions above in this Appendix and, by enrolling and participating in the ESPP, I agree to such terms. In this regard, upon request of the Company or the Employer, I agree to provide any executed data privacy consent form (or any other agreements or consents that may be required by the Employer or the Company) should the Company and/or the Employer deem such agreement or consent necessary

under applicable data privacy laws, either now or in the future. I understand I will not be able to participate in the ESPP if I fail to execute any such consent or agreement.

Securities Law Information. The offer to participate in the ESPP and the shares of Common Stock to be purchased under the ESPP are available only for Eligible Employees. It is not a public offer of securities by a Taiwanese company. Therefore, it is exempt from registration in Taiwan.

Exchange Control Information. I may acquire and remit foreign currency (including proceeds from the sale of shares of Common Stock and the receipt of any dividends paid on such shares) into and out of Taiwan up to US$5,000,000 per year. If the transaction amount is TWD500,000 or more in a single transaction, I must submit a Foreign Exchange Transaction Form and also provide supporting documentation to the satisfaction of the remitting bank.

Authorization for Participation in the ESPP. I hereby authorize the Employer, the Company and any Subsidiary or Affiliate to remit my accumulated payroll deductions under the ESPP, on my behalf, to the United States of America, to purchase shares of Common Stock under the ESPP.

Upon request of the Company or the Employer, I agree to execute a power of attorney and any other agreements or consents that may be required to enable the Employer, the Company or any Subsidiary or Affiliate or any third party designated by the Employer or the Company to remit my accumulated payroll deductions from Thailand for the purchase of shares of Common Stock. I understand that if I fail to execute a power of attorney or any other form of agreement or consent that is required for the remittance of my payroll deductions, I will not be able to participate in the ESPP.

Exchange Control Information. I acknowledge that I am required to immediately repatriate the proceeds from the sale of shares of Common Stock to Thailand if the funds received in a single transaction are US $1,000,000 or more, unless I can rely on an applicable exemption (e.g., where the funds will be used offshore for any permissible purposes under exchange control regulations and the relevant form and supporting documents have been submitted to a commercial bank in Thailand). Any foreign currency repatriated to Thailand must either be converted to Thai Baht or deposited into a foreign currency deposit account within 360 days of repatriation. I must specifically report the inward remittance to the Bank of Thailand on a foreign exchange transaction form. If I fail to comply with these obligations, I may be subject to penalties assessed by the Bank of Thailand. I acknowledge that I should consult my personal legal advisor prior to

taking any action with respect to remittance of proceeds from the sale of shares of Common Stock into Thailand. I am responsible for ensuring compliance with all exchange control laws in Thailand.

Securities Law Information. By electing to participate in the ESPP, I understand and agree that I am not permitted to sell any shares of Common Stock acquired under the ESPP in Turkey. The shares of Common Stock are currently traded on the Nasdaq Stock Market, which is located outside of Turkey, under the ticker symbol “PANW” and the shares may be sold through this exchange.

Financial Intermediary Information. Activity by Turkish residents related to investments in foreign securities (e.g., the sale of shares of Common Stock under the ESPP) must be conducted through a bank or financial intermediary institution licensed by the Turkish Capital Markets Board and should be reported to the Turkish Capital Markets Board. I understand that I am solely responsible for complying with this requirement and I should contact my personal legal advisor for further information regarding my obligations in this respect.

Nature of Grant. The following provision supplements Section 5 of the Global Subscription Agreement:

I acknowledge that the ESPP and related benefits do not constitute a component of my “wages” for any legal purpose. Therefore, the ESPP and related benefits will not be included and/or considered for purposes of calculating any and all labor benefits, such as social insurance contributions and/or any other labor-related amounts which will be payable.

Securities Law Information. Participation in the ESPP is being offered only to selected employees and is in the nature of providing equity incentives to Eligible Employees in the United Arab Emirates. The ESPP and the Agreement are intended for distribution only to such employees and must not be delivered to, or relied on by, any other person. Prospective purchasers of the securities offered should conduct their own due diligence on the securities. If I do not understand the contents of the ESPP or the Agreement, I understand that I should consult an authorized financial adviser. The Emirates Securities and Commodities Authority has no responsibility for reviewing or verifying any documents in connection with the ESPP, and neither the Ministry of Economy nor the Dubai Department of Economic Development have approved the ESPP or the Agreement nor taken any steps to verify the information set out therein and have no responsibility for such documents.

Joint Election. As a condition of my participation in the ESPP, I agree to accept any liability for secondary Class 1 NICs (“Employer NICs”) and, to the extent permissible, the employer portion of the Health and Social Care levy, which may be payable by the Company or the Employer with respect to the purchase of the shares of Common Stock or otherwise payable in connection with my participation in the ESPP. Without prejudice to the foregoing, I agree to enter into the joint election with the Company and/or the Employer attached hereto as Exhibit D (the “Election”), the form of such Election being formally approved by HM Revenue and Customs (“HMRC”), and any other consent or elections required to accomplish the transfer of the Employer NICs to me. I further agree to execute such other joint elections as may be required between me and any successor to the Company and/or the Employer. I agree to enter into an Election prior to any event giving rise to Employer NICs. I further agree that the Company and/or the Employer may collect the Employer NICs by any of the means set forth in Section 4 of the Global Subscription Agreement.

If I do not enter into an Election prior to the purchase of shares of Common Stock, I will not be entitled to purchase shares unless and until I enter into an Election, without any liability to the Company, the Employer or any other Subsidiary or Affiliate.

Responsibility for Taxes. The following supplements Section 4 of the Global Subscription Agreement:

Without limitation to Section 4 of the Global Subscription Agreement, I agree that I am liable for all Tax-Related Items and hereby covenant to pay all such Tax-Related Items as and when requested by the Company or the Employer or by HMRC (or any other tax authority or any other relevant authority). I also agree to indemnify and keep indemnified the Company and the Employer against any Tax–Related Items that they are required to pay or withhold or have paid or will pay to HMRC (or any other tax authority or any other relevant authority) on my behalf.

Notwithstanding the foregoing, if I am a director or executive officer of the Company (within the meaning of Section 13(k) of the Exchange Act), I may not be able to indemnify the Company or the Employer for the amount of any income tax not collected from or paid by me, as it may be considered a loan. In this case, the amount of any income tax not collected within 90 days of the end of the U.K. tax year in which the event giving rise to the Tax-Related Items occurs may constitute an additional benefit to me on which additional income tax and NICs may be payable. I understand that I will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for paying the Company and/or Employer for the value of any employee NICs due on this additional benefit, which may be collected from me by the Company or the Employer by any of the means referred to in Section 4 of the Global Subscription Agreement.

Palo Alto Networks, Inc. (the “Company” or the “Issuer”) offers to its non-U.S. eligible employees (including employees in the EU/EEA and the United Kingdom) the opportunity to purchase shares of common stock, par value USD $0.0001 (the "Shares"), under the 2012 Employee Stock Purchase Plan, as amended and restated (the “Plan”), at a discounted purchase price through contributions that are made by payroll deductions. This information document provides information about the number and nature of the securities and the reasons for and details of the offer or allotment. To that end, this information document describes the Issuer, the Plan, the grant of purchase rights under the Plan and the Shares to be purchased.

To the extent offers of shares under the Plan are offers of securities to the public in the EU/EEA and the United Kingdom, the Issuer can claim an exemption from the obligation to publish a prospectus which meets the requirements set forth in Regulation (EU) 2017/1129 of the European Parliament and of the Council of 14 June 2017 (the "Prospectus Regulation") and the United Kingdom Prospectus Regulation Rules (“PRR”), respectively. Article 1(4)(i) of the Prospectus Regulation and Rule 1.2.3(4)(i) of the PRR exempt issuers from the obligation to publish a prospectus if the securities are offered to existing or former directors or employees by their employer or by an affiliated undertaking provided that the present document is made available to the eligible employees (the "Exemption"). The Exemption has been incorporated into United Kingdom domestic law in Rule 1.2.3 of the United Kingdom Prospectus Rules contained in the Financial Conduct Authority's Handbook. Accordingly, in reliance on the Exemption, for offers under the Plan made after this information document is made available to eligible employees, the Issuer has not prepared or filed a prospectus with any competent regulatory authority in the EU/EEA or the United Kingdom in relation to offers made under the Plan, and no such prospectus has been approved and/or published in the EU/EEA or the United Kingdom.

This document does not constitute a prospectus. Instead, this document contains the information that the Company must make available to employees in the EU/EEA and the United Kingdom in order to comply with the Exemption.

The Issuer is Palo Alto Networks, Inc., a U.S. publicly-traded corporation which has listed its Shares on the Nasdaq stock exchange (“Nasdaq”) under the ticker symbol "PANW." The International Securities Identification Number (the "ISIN") for the Shares is US6974351057. The U.S. security identification number (the "CUSIP number") for the Shares is ###-###-####.

The Issuer’s address is 3000 Tannery Way, Santa Clara, California 95054, U.S.A.

Additional information about the Issuer, as well as the current trading price of the Shares and the total number of Shares that are issued and outstanding, can be found on its website at https://investors.paloaltonetworks.com. Filings made by the Company with the U.S. Securities and Exchange

Commission ("SEC") are available on its website at www.sec.gov. You also can access these filings through the Investor Relations section of the Company’s website, or you can request copies of the filings by contacting the Company’s Investor Relations Department at:

The purpose of the Plan is to provide eligible employees of the Company and subsidiaries or affiliates of the Company that have been designated by the Administrator (as defined below) as eligible to participate in the Plan (“Designated Companies”) with an opportunity to purchase Shares through accumulated contributions. The Company intends for the Plan to have two components: a component that is intended to qualify as an “employee stock purchase plan” under Section 423 of the U.S. Internal Revenue Code of 1986 (the “423 Component”) and a component that is not intended to qualify as such (the “Non‐423 Component”).

The Plan is offered on a wholly discretionary basis. The Plan is administered by the Company’s Board of Directors (“Board”), or a committee appointed by the Board (the “Administrator”). The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to designate separate offerings under the Plan, to designate subsidiaries and affiliates of the Company as participating in the 423 Component or Non‐423 Component, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan.

Generally, all individuals who are common law employees of the Company or a Designated Company and are customarily employed for at least twenty hours per week and more than five months in any calendar year are eligible to participate in the Plan. However, the Administrator also may determine (subject to the terms of the Plan) that certain individuals will or will not be eligible to participate in the Plan if they have not completed at least two years of service since their last hire date (or such lesser period of time as may be determined by the Administrator in its discretion), or they customarily work no more than twenty hours per week or five months per calendar year (or such lesser period of time as may be determined by the Administrator in its discretion) as required under applicable local law.

Each “Offering Period” under the Plan is approximately twenty-four months in duration, commencing on the first trading day on or after February 28 and August 31 of each year and ending on the first trading day on or after February 28 and August 31, approximately twenty-four months later. Each Offering Period consists of four six-month “Purchase Periods” during which your payroll deductions or other contributions are accumulated under the Plan.

If you are eligible to participate in the Plan, you may become a participant by submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to the applicable enrollment date for the Offering Period, a properly completed subscription agreement authorizing

Contributions (as defined below) in the form provided by the Administrator for such purpose, or following an electronic or other enrollment procedure determined by the Administrator.

Once you become a participant in the Plan, you will automatically participate in each succeeding Offering Period unless you either withdraw from the Plan or you cease to be an eligible employee. You are not required to complete any additional subscription agreement, form or procedure in order to continue participation in the Plan, unless requested by the Administrator for legal or administrative reasons.

You may contribute through contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) (“Contributions”) an amount not exceeding fifteen percent (15%) of your eligible Compensation (as defined below) toward the purchase of Shares under the Plan, subject to the terms of the Plan. The payroll deductions will commence on the first payday following the first trading day of the Offering Period and will continue until the first trading day on or after February 28 and August 31 of each Purchase Period (the “Exercise Date”) unless sooner altered or terminated as provided in the Plan. Contributions may be made in whole percentages only.

For purposes of the Plan, your “Compensation” includes base straight time gross earnings, payments for overtime and shift premium, but excludes payments for commissions, incentive compensation, bonuses and other similar compensation. The Administrator, in its discretion, may, on a uniform and nondiscriminatory basis, establish a different definition of Compensation for a subsequent Offering Period.

Unless otherwise determined by the Administrator, during a Purchase Period, you may not increase the rate of your Contributions and may only decrease the rate of your Contributions one time per Purchase Period. Any such decrease during a Purchase Period requires you to properly complete and submit to the Company’s stock administration office (or another Company designee), on or before a date determined by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in Contribution rate or follow an electronic or other procedure prescribed by the Administrator.

The purchase price is eighty-five percent (85%) of (i) the fair market value of the Shares on the first trading day of the Offering Period or (ii) the fair market value of the Shares on the applicable Exercise Date, whichever is lower. The fair market value is generally the closing price of a Share on the Nasdaq on the Exercise Date.

On each Exercise Date, so long as the Plan remains in effect and provided that you have not withdrawn from the Offering Period in accordance with the requirements of the Plan, the Company shall apply the funds then in your account to the purchase of whole Shares. Any Contributions accumulated in your account which are not sufficient to purchase a full Share will be promptly refunded to you promptly following an Exercise Date.

The maximum number of Shares initially reserved for issuance under the Plan was 1,000,000 Shares. However, the number of Shares available for issuance under the Plan is increased on an annual basis in accordance with the terms of the Plan.

As soon as reasonably practicable after each Exercise Date, the Company will arrange the delivery to each participant of the Shares purchased upon exercise of his or her purchase right in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that Shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that Shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of dispositions of such Shares.

The Company has selected a broker to administer the issuance of Shares under the Plan (currently E*TRADE Corporate Financial Services, Inc.) (the “Broker”). At the time of enrollment, you were or will be asked to open an account with the Broker. You will not have to pay a fee for opening an account with the Broker for the management of your account or for the purchase of Shares. You are responsible for all the commissions and fees related to any sale or transfer of the Shares from the account with the Broker. In addition, the SEC applies a fee to most securities transactions at a rate determined by the SEC. Such commissions and fees are subject to change at any time.

You may withdraw from the Plan at least one (1) business day prior to an Exercise Date by submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or following an electronic or other withdrawal procedure determined by the Administrator. Upon withdrawal from the Plan, all of your accumulated payroll deductions will be returned to you, without interest (unless otherwise required by applicable law), promptly after receipt of notice of withdrawal, and your purchase right for the Offering Period will be automatically terminated, and no further Contributions for the purchase of Shares will be made for such Offering Period..

If you voluntarily withdraw from the Plan, you may not resume participation in the Plan during the same Offering Period. However, you may participate in any Offering Period under the Plan which begins on a date after such withdrawal by completing a subscription agreement in the same manner as described in the Plan for initial participation in the Plan.

If you cease to be an eligible employee, for any reason, you will be deemed to have elected to withdraw from the Plan and the Contributions credited to your account during the Offering Period but not yet used to purchase Shares under the Plan will be returned to you without interest (unless otherwise required by applicable law), and your purchase right will be automatically terminated.

Neither Contributions credited to your account nor any rights with regard to the exercise of a purchase right or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution). Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with the Plan.

The Shares in this offering under the Plan are registered on a registration statement on Form S-8 with the SEC and are generally freely transferable (subject however to any transferability restrictions resulting from applicable insider trading laws and the Company's insider trading policy).

The Plan is intended to provide Shares for investment and not for resale. The Company does not, however, intend to restrict or influence any participant in the conduct of his or her own affairs. Therefore, you may sell Shares purchased under the Plan at any time you choose, subject to compliance with any applicable securities laws. You assume the risk of any market or currency fluctuations in the price of the Shares. Moreover, you should be aware of the risks of investing in Shares as described, in particular, in the “Risk Factors” section of certain of the Company’s SEC filings.

The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of Shares on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to the Plan).

If the Offering Periods are terminated prior to expiration, all amounts then credited to participants’ accounts that have not been used to purchase Shares will be returned to participants without interest (unless otherwise required by applicable laws) as soon as administratively practicable.

The Shares acquired under the Plan are shares of the Company’s common stock, which will allow a shareholder to participate in:

•Dividends – If and when declared payable by the Company as authorized in its bylaws.

•Voting – A shareholder will be entitled to vote at the Company’s shareholder meetings where each of the Shares will count for one vote.

•Information Reporting – A shareholder will have the right to receive certain information from the Company such as the Company’s annual report to shareholders and annual proxy statement. The Company can make such information available for its shareholders at its office and/or via its website.

•Liquidation Proceeds – In the event of liquidation, dissolution or winding up of the Company, the holders of Shares are entitled to share ratably in all assets remaining after payment of or provisions for the Company's liabilities, subject to prior rights or preferred stock, if any, then outstanding.

•No Preemptive, Redemptive or Conversion Provisions – The Shares are not entitled to preemptive rights and are not subject to conversion or redemption.

With respect to Shares subject to the purchase right under the Plan, you will not be deemed a shareholder with the above rights until the Shares have been purchased and delivered to you.

The Company may issue other classes of shares and/or securities which are not part of this offer and the Plan.

Note that the Company may, at any time, but subject to the passing of a shareholder vote, amend its Bylaws and/or Certificate of Incorporation in a way that impacts the rights of holders of the Shares. These documents can be found on the Company's website at https://investors.paloaltonetworks.com.
