F5 NETWORKS, INC 
2011 EMPLOYEE STOCK PURCHASE PLAN


1.PURPOSE.
(a)   The purpose of the Plan is to provide a means by which Employees of the Company and certain designated Affiliates may be given an opportunity to purchase Shares of the Company.
(b)   The Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Affiliates.
(c)   The Company intends that the Rights to purchase Shares granted under the Plan be considered options issued under an “employee stock purchase plan,” as that term is defined in Section 423(b) of the Code.


2.    DEFINITIONS.
Certain terms used in the Plan have the meanings set forth in Appendix I.


3.    ADMINISTRATION.
(a)   The Board shall administer the Plan unless and until the Board delegates administration to a Committee, as provided in subparagraph 3(d). Whether or not the Board has delegated administration, the Board shall have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan.
(b)   The Board (or the Committee) shall have the power, subject to, and within the limitations of, the express provisions of the Plan:
(i)   To determine when and how Rights to purchase Shares shall be granted and the provisions of each Offering of such Rights (which need not be identical).
(ii)   To designate from time to time which Affiliates of the Company shall be eligible to participate in the Plan.
(iii)   To construe and interpret the Plan and Rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this 







power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.
(iv)   To amend the Plan as provided in paragraph 14.
(v)   Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote the best interests of the Company and its Affiliates and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan.
(c)   Without limitation on paragraph 3(b) and without amending the Plan, the Board (or the Committee) may grant rights or establish other procedures to provide benefits to Eligible Employees outside of the United States on such terms and conditions different from those specified in this Plan as may, in the judgment of the Board (or the Committee), be necessary or desirable to foster and promote achievement of the purposes of the Plan and shall have the authority to adopt such modifications, procedures, subplans and the like as may be necessary or desirable (i) to comply with provisions of the laws or regulations or conform to the requirements to operate the Plan in a qualified or tax or accounting advantageous manner in other countries or jurisdictions in which the Company or any other Employer may operate or have employees, (ii) to ensure the viability of the benefits from the Plan to Eligible Employees employed in such countries or jurisdictions and (iii) to meet the objectives of the Plan. Further to the foregoing and notwithstanding anything to the contrary herein, the Board (or the Committee) may grant Rights under one or more subplans which do not qualify as an “employee stock purchase plan” under Section 423 of the Code and are not subject to the requirements of Section 423 of the Code. 
(d)   The Board may delegate administration of the Plan to a Committee of the Board composed of two (2) or more members, all of the members of which Committee may be, in the discretion of the Board Non-Employee Directors. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or such a subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan.


4.    SHARES SUBJECT TO THE PLAN.
(a)   Subject to the provisions of paragraph 13 relating to adjustments upon changes in securities, the Shares that may be sold pursuant to Rights granted under the Plan shall not exceed in the aggregate ten million (10,000,000) Shares. If any Right granted under the Plan shall for 







any reason terminate without having been exercised, the Shares not purchased under such Right shall again become available for the Plan.
(b)   The Shares subject to the Plan may be unissued Shares or Shares that have been bought on the open market at prevailing market prices or otherwise.


5.    GRANT OF RIGHTS; OFFERING.
(a)   The Board may from time to time grant or provide for the grant of Rights to purchase Shares of the Company under the Plan to Eligible Employees in an Offering on an Offering Date or Dates selected by the Board. Each Offering shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate, which shall comply with the requirements of Section 423(b)(5) of the Code that all Employees granted Rights to purchase Shares under the Plan shall have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering shall include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering shall be effective, which period shall not exceed twenty-seven (27) months beginning with the Offering Date, and the substance of the provisions contained in paragraphs 6 through 9, inclusive.
(b)   If a Participant has more than one Right outstanding under the Plan, unless he or she otherwise indicates in agreements or notices delivered hereunder: (i) each agreement or notice delivered by that Participant will be deemed to apply to all of his or her Rights under the Plan, and (ii) an earlier-granted Right (or a Right with a lower exercise price, if two Rights have identical grant dates) will be exercised to the fullest possible extent before a later-granted Right (or a Right with a higher exercise price if two Rights have identical grant dates) will be exercised.


6.    ELIGIBILITY.
(a)   Rights may be granted only to Employees of the Company or, as the Board may designate as provided in subparagraph 3(b), to Employees of an Affiliate. Except as provided in subparagraph 6(b), an Employee shall not be eligible to be granted Rights under the Plan unless, on the Offering Date, such Employee has been in the employ of the Company or the Affiliate, as the case may be, for such continuous period preceding such grant as the Board may require, but in no event shall the required period of continuous employment be equal to or greater than two (2) years.







(b)   The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a Right under that Offering, which Right shall thereafter be deemed to be a part of that Offering. Such Right shall have the same characteristics as any Rights originally granted under that Offering, as described herein, except that:
(i)   the date on which such Right is granted shall be the “Offering Date” of such Right for all purposes, including determination of the exercise price of such Right;
(ii)   the period of the Offering with respect to such Right shall begin on its Offering Date and end coincident with the end of such Offering; and
(iii)   the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Right under that Offering.
(c)   No Employee shall be eligible for the grant of any Rights under the Plan if, immediately after any such Rights are granted, such Employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 6(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding rights and options shall be treated as stock owned by such Employee.
(d)   An Eligible Employee may be granted Rights under the Plan only if such Rights, together with any other Rights granted under all Employee Stock Purchase Plans of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such Eligible Employee’s rights to purchase Shares of the Company or any Affiliate to accrue at a rate which exceeds twenty five thousand dollars ($25,000) of the fair market value of such Shares (determined at the time such Rights are granted) for each calendar year in which such Rights are outstanding at any time.
(e)   The Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to participate.









7.    RIGHTS; PURCHASE PRICE.
(a)   On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, shall be granted the Right to purchase up to the number of Shares purchasable either:
(i)   with a percentage designated by the Board not exceeding fifteen percent (15%) of such Employee’s Earnings (as defined by the Board in each Offering) during the period which begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering; or
(ii)   with a maximum dollar amount designated by the Board that, as the Board determines for a particular Offering, (1) shall be withheld, in whole or in part, from such Employee’s Earnings (as defined by the Board in each Offering) during the period which begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering and/or (2) shall be contributed, in whole or in part, by such Employee during such period.
(b)   The Board shall establish one or more Purchase Dates during an Offering on which Rights granted under the Plan shall be exercised and purchases of Shares carried out in accordance with such Offering.
(c)   In connection with each Offering made under the Plan, the Board may specify a maximum amount of Shares that may be purchased by any Participant as well as a maximum aggregate amount of Shares that may be purchased by all Participants pursuant to such Offering. In addition, in connection with each Offering that contains more than one Purchase Date, the Board may specify a maximum aggregate amount of Shares which may be purchased by all Participants on any given Purchase Date under the Offering. If the aggregate purchase of Shares upon exercise of Rights granted under the Offering would exceed any such maximum aggregate amount, the Board shall make a pro rata allocation of the Shares available in as nearly a uniform manner as shall be practicable and as it shall deem to be equitable. Unless a different maximum amount of Shares that may be purchased by any Participant during an Offering is determined by the Board prior to the start of an Offering, the maximum amount of Shares that may be purchased by any Participant during an Offering is 10,000 Shares.
(d)   The purchase price of Shares acquired pursuant to Rights granted under the Plan shall be not less than the lesser of:
(i)   an amount equal to eighty-five percent (85%) of the fair market value of the Shares on the Offering Date; or







(ii)   an amount equal to eighty-five percent (85%) of the fair market value of the Shares on the Purchase Date.
8.    PARTICIPATION; WITHDRAWAL; TERMINATION.
(a)   An Eligible Employee may become a Participant in the Plan pursuant to an Offering by delivering a participation agreement to the Company within the time specified in the Offering, in such form as the Company provides. Each such agreement shall authorize payroll deductions of up to the maximum percentage specified by the Board of such Employee’s Earnings during the Offering (as defined in each Offering). The payroll deductions made for each Participant shall be credited to a bookkeeping account for such Participant under the Plan and either may be deposited with the general funds of the Company or may be deposited in a separate account in the name of, and for the benefit of, such Participant with a financial institution designated by the Company. To the extent provided in the Offering, a Participant may reduce (including to zero) or increase such payroll deductions. To the extent provided in the Offering, a Participant may begin such payroll deductions after the beginning of the Offering. A Participant may make additional payments into his or her account only if specifically provided for in the Offering and only if the Participant has not already had the maximum permitted amount withheld during the Offering.
(b)   At any time during an Offering, a Participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company provides. Such withdrawal may be elected at any time prior to the end of the Offering except as provided by the Board in the Offering. Upon such withdrawal from the Offering by a Participant, the Company shall distribute to such Participant all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire Shares for the Participant) under the Offering, without interest unless otherwise specified in the Offering, and such Participant’s interest in that Offering shall be automatically terminated. A Participant’s withdrawal from an Offering will have no effect upon such Participant’s eligibility to participate in any other Offerings under the Plan but such Participant will be required to deliver a new participation agreement in order to participate in subsequent Offerings under the Plan.
(c)   Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of any participating Employee’s employment with the Company or a designated Affiliate for any reason (subject to any post-employment participation period required by law) or other lack of eligibility. The Company shall distribute to such terminated Employee all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire Shares for the terminated Employee) under the Offering, without interest unless otherwise specified in the Offering. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of 







the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.
(d)   Rights granted under the Plan shall not be transferable by a Participant otherwise than by will or the laws of descent and distribution and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such Rights are granted.


9.    EXERCISE.
(a)   On each Purchase Date specified therefor in the relevant Offering, each Participant’s accumulated payroll deductions and other additional payments specifically provided for in the Offering (without any increase for interest) will be applied to the purchase of Shares up to the maximum amount of Shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional Shares shall be issued upon the exercise of Rights granted under the Plan unless specifically provided for in the Offering.
(b)   Unless otherwise specifically provided in the Offering, the amount, if any, of accumulated payroll deductions remaining in any Participant’s account after the purchase of Shares that is equal to the amount required to purchase one or more whole Shares on the final Purchase Date of the Offering shall be distributed in full to the Participant at the end of the Offering, without interest. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.
(c)   No Rights granted under the Plan may be exercised to any extent unless the Shares to be issued upon such exercise under the Plan (including Rights granted thereunder) are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not so registered or in such compliance, no Rights granted under the Plan or any Offering shall be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve (12) months and the Purchase Date shall in no event be more than 







twenty-seven (27) months from the Offering Date. If, on the Purchase Date of any Offering hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, no Rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering (reduced to the extent, if any, such deductions have been used to acquire Shares) shall be distributed to the Participants, without interest unless otherwise specified in the Offering. If the accumulated payroll deductions have been deposited with the Company’s general funds, then the distribution shall be made from the general funds of the Company, without interest. If the accumulated payroll deductions have been deposited in a separate account with a financial institution as provided in subparagraph 8(a), then the distribution shall be made from the separate account, without interest unless otherwise specified in the Offering.


10.    ISSUANCE OF SHARES.
(a)   If on a given Purchase Date, the number of Shares with respect to which Rights are to be exercised exceeds the number of Shares then available under the Plan, the Board shall make a pro rata allocation of the Shares remaining available under the Plan in as nearly a uniform manner as shall be practical and as it shall determine to be equitable.
(b)   If the Company is unable to obtain from any regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Shares under the Plan, the Company shall be relieved from any liability for failure to issue and sell Shares upon exercise of such Rights unless and until such authority is obtained.


11.    USE OF PROCEEDS FROM SHARES.
Proceeds from the sale of Shares pursuant to Rights granted under the Plan shall constitute general funds of the Company.


12.    RIGHTS AS A SHAREHOLDER.
A Participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, Shares subject to Rights granted under the Plan unless and until the Participant’s Shares acquired upon exercise of Rights under the Plan are issued. No adjustment will be made for dividends or other rights for which the record date is prior to the date of issuance.









13.    ADJUSTMENTS UPON CHANGES IN SECURITIES.
(a)   If any change is made in the Shares subject to the Plan, or subject to any Right, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of Shares subject to the Plan pursuant to subparagraph 4(a), and the outstanding Rights will be appropriately adjusted in the class(es), number of Shares and purchase limits of such outstanding Rights. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction that does not involve the receipt of consideration by the Company.)
(b)   In the event of: (i) a dissolution, liquidation, or sale of all or substantially all of the assets of the Company; (ii) a merger or consolidation in which the Company is not the surviving corporation; or (iii) a reverse merger in which the Company is the surviving corporation but the Shares outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then: (1) any surviving or acquiring corporation shall assume Rights outstanding under the Plan or shall substitute similar rights (including a right to acquire the same consideration paid to Shareholders in the transaction described in this subparagraph 13(b)) for those outstanding under the Plan, or (2) in the event any surviving or acquiring corporation refuses to assume such Rights or to substitute similar rights for those outstanding under the Plan, then, as determined by the Board in its sole discretion such Rights may continue in full force and effect or the Participants’ accumulated payroll deductions (exclusive of any accumulated interest which cannot be applied toward the purchase of Shares under the terms of the Offering) may be used to purchase Shares immediately prior to the transaction described above under the ongoing Offering and the Participants’ Rights under the ongoing Offering thereafter terminated.


14.    AMENDMENT OF THE PLAN.
(a)   The Board at any time, and from time to time, may amend the Plan. However, except as provided in paragraph 13 relating to adjustments upon changes in securities and except as to minor amendments to benefit the administration of the Plan, to take account of a change in legislation or to obtain or maintain favorable tax, exchange control or regulatory treatment for Participants or the Company or any Affiliate, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary for the Plan to satisfy the requirements of Section 423 of the Code and any Nasdaq or other securities 







exchange listing requirements. Currently under the Code, shareholder approval within twelve (12) months before or after the adoption of the amendment is required where the amendment will:
(i)   Increase the amount of Shares reserved for Rights under the Plan;
(ii)   Modify the provisions as to eligibility for participation in the Plan to the extent such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code; or
(iii)   Modify the Plan in any other way if such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code.
(b)   It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Employee Stock Purchase Plans and/or to bring the Plan and/or Rights granted under it into compliance therewith.
(c)   Rights and obligations under any Rights granted before amendment of the Plan shall not be impaired by any amendment of the Plan, except with the consent of the person to whom such Rights were granted, or except as necessary to comply with any laws or governmental regulations, or except as necessary to ensure that the Plan and/or Rights granted under the Plan comply with the requirements of Section 423 of the Code or are exempt from or comply with the requirements of Section 409A of the Code.


15.    TERMINATION OR SUSPENSION OF THE PLAN.
(a)   The Board in its discretion may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate at the time that all of the Shares subject to the Plan’s reserve, as increased and/or adjusted from time to time, have been issued under the terms of the Plan. No Rights may be granted under the Plan while the Plan is suspended or after it is terminated.
(b)   Rights and obligations under any Rights granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except as expressly provided in the Plan or with the consent of the person to whom such Rights were granted, or except as necessary to comply with any laws or governmental regulation, or except as necessary to ensure that the Plan and/or Rights granted under the Plan comply with the requirements of Section 423 of the Code.









16.    TREATMENT OF ELIGIBLE EMPLOYEES OUTSIDE OF THE UNITED STATES.
Eligible Employees who are paid in foreign currency, and who contribute foreign currency to the Plan through contributions or payroll deductions will have such amounts converted to U.S. dollars. The exchange rate and method for such conversion will be determined as prescribed by the Board or Committee. In no event will any procedure implemented for dealing with exchange rate fluctuations that may occur during an Offering result in a purchase price below the purchase price permitted under subparagraph 7(d) of the Plan. Each Eligible Employee shall bear the risk of any currency exchange fluctuations (if applicable) between the date on which any Eligible Employee amounts are converted to U.S. dollars and the Purchase Date.


17.    WITHHOLDING.
The Employer shall have the power and the right to (a) deduct, withhold or cause the sale of Shares purchased pursuant to an Offering under the Plan to obtain, (b) deduct or withhold from any other compensation to the Participant, or (c) require a Participant to remit to the Employer, an amount sufficient to satisfy Federal, state and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of the Plan.


18.    SECTION 409A.
Rights under the Plan are intended to be exempt from the application of Section 409A of the Code and the Plan is intended to be interpreted consistent with such intention. Notwithstanding the foregoing, neither the Company nor the Board shall have any liability to any Participant or any other party if the Rights under the Plan are not exempt from or compliant with Section 409A of the Code.


19.    NO RIGHT OF EMPLOYMENT.
Neither the grant nor the exercise of any Right under the Plan nor anything in this Plan shall impose upon the Company or any other Employer any obligation to employ or continue to employ any Eligible Employee. The right of the Company or any other Employer to terminate any Employee shall not be diminished or affected because any Rights have been granted to such Employee.









20.    OBLIGATION TO MAINTAIN SHARES WITH BROKER.
Without limitation on the Participant’s or former Participant’s ability to sell, transfer, or otherwise makes a disposition of Shares purchased pursuant to an Offering under the Plan and without limitation on paragraph 3, Participants and former Participants must maintain any Shares purchased pursuant to an Offering under the Plan at the broker designated by the Committee unless the Committee determines otherwise.


21.    EFFECTIVE DATE AND HISTORY OF PLAN.
The 1999 Employee Stock Purchase Plan was originally adopted by the Board and approved by shareholders in 1999 and subsequently amended as set forth on Appendix II. The 2011 Employee Stock Purchase Plan is an amendment and restatement of the 1999 Employee Stock Purchase Plan, as amended.
