preceding the payroll date for which it is to be effective.

to the Company or a designated Related Corporation in such form as the Company provides. A Participant who has withdrawn from an Offering shall not again participate in such Offering, but may participate in subsequent Offerings under the Plan in
accordance with the terms of the Plan and the terms of such subsequent Offerings. 
 (d) Notwithstanding
the foregoing or any other provision of this Offering document or of the Plan to the contrary, neither the enrollment of any Eligible Employee in the Plan nor any forms relating to participation in the Plan shall be given effect until such time as a
registration statement covering the shares reserved under the Plan that are subject to the Offering has been filed by the Company and has become effective. 
 (e) If the provisions of Section 5(d) are applicable, the Company shall establish such procedures as will enable the purposes of the Plan to be satisfied while complying with applicable
securities laws. Such procedures may include, for example, allowing Participants to participate other than by means of payroll deduction and/or allowing Participants to decrease their level of participation during an Offering to a level other than
zero percent (0%). 
 Except as otherwise provided by the Company pursuant to the preceding sentence, for the
Initial Offering ending March 31, 2007, no payroll deductions shall be required from the Eligible Employee until such time as the Eligible Employee affirmatively elects to commence such payroll deductions (which may be for a percentage that is
less than fifteen percent (15%) of the Eligible Employee’s Earnings) following the Eligible Employee’s receipt of the Securities Act prospectus for the Plan. Each Eligible Employee shall automatically be enrolled in the Initial
Offering with a contribution rate equal to fifteen percent (15%) of the Eligible Employee’s Earnings, subject to the limitations set forth in Sections 3(c)-(e). If an Eligible Employee elects not to authorize payroll deductions for the
purchase of shares during the Initial Offering, the Eligible Employee instead may purchase shares of Common Stock under the Plan by delivering a single cash payment for the purchase of such shares to the Company or a designated Related

  
 4. 

 
Corporation prior to the ten (10) day period immediately preceding the Purchase Date under the Initial Offering (or such shorter period of time determined by the Company and communicated to
Participants). To the extent that the Eligible Employee’s payroll deductions for the Initial Offering are less than fifteen percent (15%) of Earnings paid to the Eligible Employee during the Initial Offering, the Eligible Employee may make
an additional cash payment at any time to the Company or a designated Related Corporation prior to the ten (10) day period immediately preceding the Purchase Date under the Initial Offering (or such shorter period of time determined by the
Company and communicated to Participants) in order to fund the purchase of shares of Common Stock purchased on behalf of the Eligible Employee on the Purchase Date under the Initial Offering. If an Eligible Employee neither elects to authorize
payroll deductions nor chooses to make a cash payment in accordance with the foregoing, then no shares shall be purchased on behalf of the Eligible Employee on the Purchase Date under the Initial Offering. 

After the end of the Initial Offering, in order to participate in any subsequent Offerings, an Eligible Employee must
enroll and authorize payroll deductions prior to the commencement of the Offering, in accordance with Section 5(a); provided, however, that once an Eligible Employee enrolls in an Offering and authorizes payroll deductions (including in
connection with the Initial Offering), the Eligible Employee automatically shall be enrolled for all subsequent Offerings until he or she elects to withdraw from an Offering pursuant to Section 5(c) above or terminates his or her participation
in the Plan. 
  

	 6.
	 PURCHASES. 

 Subject to the limitations contained herein, on each Purchase Date, each Participant’s Contributions (without any increase for interest) shall be applied to the purchase of whole shares, up to the
maximum number of shares permitted under the Plan and the Offering. 
  

	 7.
	 NOTICES AND AGREEMENTS. 

Any notices or agreements provided for in an Offering or the Plan shall be given in writing, in a form provided by the
Company (including documents delivered in electronic form, if authorized by the Committee), and unless specifically provided for in the Plan or this Offering, shall be deemed effectively given upon receipt or, in the case of notices and agreements

	 8.
	 EXERCISE CONTINGENT ON STOCKHOLDER APPROVAL.

 The Purchase Rights granted under an Offering are subject to the approval of the Plan by the
stockholders of the Company as required for the Plan to obtain treatment as an Employee Stock Purchase Plan.

Offering. The Offering is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of an Offering and
those of the Plan (including interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan), the provisions of the Plan shall control.

times be considered a separate and distinct payment. 
 5. Excise Tax Limitation. 

(a) Notwithstanding anything contained in this Agreement to the contrary, in the event that the benefits provided by this Agreement,
together with all other payments and the value of any benefits received or to be received by Executive (“Payments”), constitute “parachute payments” within the meaning of Section 280G of the Code, and, but for this
Section 5, would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Payments shall be made to Executive either (i) in full or (ii) as to such lesser amount as would
result in no portion of the Payments being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Executive on an
after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of the Payments may be subject to the Excise Tax. The Corporation shall reduce or eliminate the Payments by first reducing or eliminating cash payments and
then by reducing those payments or benefits which are not payable in cash, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Determination (as hereinafter defined). 

(b) Unless the Corporation and Executive otherwise agree in writing, an initial determination as to whether the Payments shall be
reduced and the amount of such reduction shall be made, at the Corporation’s expense, by the accounting firm that is the Corporation’s independent accounting firm as of the date of the Change in Control (the “Accounting
Firm”). The Accounting Firm shall provide its determination (the “Determination”), together with detailed supporting calculations and documentation, to the Corporation and Executive within twenty (20) days of the Date
of Termination if applicable, or such other time as requested by the Corporation or by Executive (provided Executive reasonably believes that Executive will receive Payments which may be subject to the Excise Tax), and if the Accounting Firm
determines that there is substantial authority (within the meaning of Section 6662 of the Code) that no Excise Tax is payable by Executive with respect to a Payment or Payments, it shall furnish Executive with an opinion reasonably acceptable
to Executive that no Excise Tax will be imposed with respect to any such Payment or Payments. Within ten (10) days of the delivery of the Determination to Executive, Executive shall have the right to dispute the Determination (the
“Dispute”). If there is no Dispute, the Determination shall be binding, final and conclusive upon the Corporation and Executive. 
 (c) As a result of the uncertainty in the application of Sections 4999 and 280G of the Code, it is possible that the Payments to be made to, or provided for the benefit of, Executive either will be
greater (an “Excess Payment”) or less (an “Underpayment”) than the amounts provided for by the limitation contained in Section 5( a). 
 (i) If it is established pursuant to a final determination of a court or an Internal Revenue Service (the “IRS”) proceeding which has been finally and conclusively resolved that an Excess
Payment has been such Excess Payment shall be deemed for all 
  

  
 6 

 purposes to be a loan to Executive made on the date Executive received the Excess Payment and Executive
shall repay the Excess Payment to the Corporation on demand (but not less than ten (10) days after written notice is received by Executive) together with interest on the Excess Payment at the “Applicable Federal Rate” (as defined in
Section 1274(d) of the Code) from the date of Executive’s receipt of such Excess Payment until the date of such repayment. 
 (ii) In the event that it is determined by (A) the Accounting Firm, the Corporation (which shall include the position taken by the Corporation, or together with its consolidated group, on its federal
income tax return) or the IRS, (B) pursuant to a determination by a court, or (C) upon the resolution to Executive’s satisfaction of the Dispute that an Underpayment has occurred, the Corporation shall pay an amount equal to the
Underpayment to Executive within ten (10) days of such determination or resolution, together with interest on such amount at the Applicable Federal Rate from the date such amount would have been paid to Executive until the date of payment.

 (a) The Corporation shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Corporation
to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform it if no such succession had taken place. Unless expressly provided otherwise,
“Corporation” as used herein shall mean the Corporation as defined in this Agreement and any successor to its business and/or assets as aforesaid. 
 (b) This Agreement shall inure to the benefit of and be enforceable by Executive and Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If Executive should die while any amount would still be payable to Executive hereunder had Executive continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to Executive’s devisee, legatee or other designee or, if there is no such designee, to Executive’s estate. 

7. Miscellaneous. 
 (a) Modification or Amendment. No provision of this Agreement may be modified or amended unless such modification or amendment is agreed to in writing and signed by Executive and an authorized
officer of the Corporation as may be specifically designated by the Board or a committee thereof. 
 (b) Waiver. No
waiver by either party hereto at anytime of any breach by the other party hereto of or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. 
 (c) Complete Agreement. This Agreement constitutes the
entire agreement between Executive and the Corporation and is the complete, final and exclusive embodiment of their agreement with regard to this subject matter, and this Agreement shall supersede any prior 

 

  
 7 

 or contemporaneous written or oral agreements regarding this subject matter. No agreements or
representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement. 

(d) Non-Exclusivity of Rights. Notwithstanding Section 7(c), nothing in this Agreement shall prevent or limit
Executive’s continuing or future participation in any benefit, bonus, incentive or other plan or program provided by the Corporation (except for any severance or termination policies, plans, programs or practices) and for which Executive may
qualify, nor shall anything herein limit or reduce such rights as Executive may have under any other agreements with the Corporation (except for any severance, termination or other agreement regarding the subject matter of this Agreement). Amounts
which are vested benefits or which Executive is otherwise entitled to receive under any plan or program of the Corporation shall be payable in accordance with such plan or program, except as explicitly modified by this Agreement. 

(e) Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of
the State of California without regard to its conflicts of law principles. 
 (f) Statutory References. All references to
sections of the Exchange Act or the Code shall be deemed also to refer to any successor provisions to such sections. 
 (g)
Tax Withholding. Any payments provided for hereunder shall be paid net of any applicable withholding required under federal, state or local law. 
 (h) Section Headings. The section headings contained in this Agreement are for convenience only, and shall not affect the interpretation of this Agreement. 

(i) Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or
enforceability of any other provision of this Agreement, which shall remain in full force and effect. 
 (j)
Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. 

8. Arbitration. The parties hereby agree that any and all claims or controversies regarding this Agreement shall be resolved, to
the fullest extent permitted by law, by final, binding and confidential arbitration in Palo Alto, California conducted before a single arbitrator by Judicial Arbitration and Mediation Services/Endispute (“JAMS”) or its successor,
under the then applicable JAMS rules. By agreeing to this arbitration procedure, both parties waive the right to resolve any such dispute through a trial by jury or judge or by administrative proceeding. The arbitrator shall: (a) have the
authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision including the arbitrator’s essential findings and
conclusions and a statement of the award. The Corporation shall pay all of JAMS’ arbitration fees. Nothing in this Agreement shall prevent either party from obtaining injunctive relief in court if necessary to prevent irreparable harm pending
the conclusion of any arbitration.

 9. Fees and Expenses. In connection with a Covered Termination which occurs within
twelve (12) months after a Change in Control, the Corporation shall pay all reasonable legal fees and related expenses (including the costs of experts, evidence and counsel) incurred by Executive as they become due as a result of(a) Executive
seeking to obtain or enforce any right or benefit provided by this Agreement (including, but not limited to, any such fees and expenses incurred in connection with the Dispute whether as a result of any applicable government taxing authority
proceeding, audit or otherwise), and (b) Executive’s hearing before the Board as contemplated in Section 1 (b) of this Agreement. To the extent that any reimbursements payable to Executive pursuant to this Section 9 are
subject to the provisions of Section 409 A of the Code, such reimbursements shall be paid to Executive no later than December 31 of the year following the year in which the cost was incurred, the amount of expenses reimbursed in one year
shall not affect the amount eligible for reimbursement in any subsequent year, and Executive’s right to reimbursement under this Section 9 will not be subject to liquidation or exchange for another benefit. 

10. Settlement of Claims. The Corporation’s obligation to make the payments provided for in this Agreement and otherwise to
perform its obligations hereunder shall not be affected by any circumstances, including, without limitation, any set-off, counterclaim, recoupment, defense or other right which the Corporation may have against Executive or others. 

11. At-Will Employment. Nothing contained in this Agreement shall (a) confer upon Executive any right to continue in the
employ of the Corporation, (b) constitute any contract or agreement of employment, or (c) interfere in any way with the at-will nature of Executive’s employment with the Corporation. 

12. Miscellaneous. The Corporation shall not be required to fund or otherwise segregate assets to be used for the payment of any
benefits under this Agreement. The Corporation shall make such payments only out of its general corporate funds, and therefore its obligation to make such payments shall be subject to any claims of its other creditors having priority as to its
assets.
