2014 EQUITY INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

(NONSTATUTORY STOCK OPTION) 

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Stock Option Agreement, XenoPort, Inc. (the
“Company”) has granted you an option under its 2014 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant Notice at the exercise
price indicated in your Grant Notice. Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. 

The details of your option are as follows: 

1. VESTING. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice,
provided that vesting will cease upon the termination of your Continuous Service. 
 2. NUMBER OF
SHARES AND EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to
time for Capitalization Adjustments. 
 3. METHOD OF PAYMENT. Payment of the exercise
price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the
following: 
 (a) In the Company’s sole discretion at the time your option is exercised and provided that at the time of
exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results
in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. 

(b) In the Company’s sole discretion at the time your option is exercised and provided that at the time of exercise the Common
Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock either that you have held for the period required to avoid
a charge to the Company’s reported earnings (generally six (6) months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances or security interests, and that
are valued at Fair Market Value on the date of exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of
such shares of Common Stock in a form approved by the Company. Notwithstanding the 

  
 1. 

 
foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the
redemption of the Company’s stock. 
 4. WHOLE SHARES. You may exercise your option only for whole
shares of Common Stock. 
 5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the
contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not
exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 

6. TERM. You may not exercise your option before the commencement or after the expiration of its term. The term of your
option commences on the Date of Grant and expires upon the earliest of the following: 
 (a) thirty-six (36) months after the
termination of your Continuous Service for any reason other than your Disability or death or upon a Change in Control, provided that if during any part of such thirty-six (36) month period your option is not exercisable solely because of the
condition set forth in Section 5, your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of thirty-six (36) months after the termination of your Continuous
Service; 
 (b) thirty-six (36) months after the termination of your Continuous Service due to your Disability; 

(c) thirty-six (36) months after your death if you die either during your Continuous Service or within three (3) months after
your Continuous Service terminates; 
 (d) thirty-six (36) months after your Continuous Service terminates if termination occurs
as of, or within twelve (12) months following the effective date of a Change in Control; 
 (e) the Expiration Date indicated in
your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

7. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by delivering a notice of exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with
such additional documents as the Company may then require. 

  
 2. 

 (b) By exercising your option you agree that, as a condition to any exercise of your
option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any
substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise. 

8. TRANSFERABILITY. Your option is transferable only by will or by the laws of descent and distribution and is
exercisable only by you during your lifetime. However, you may transfer your option for no consideration upon written consent of the Board (i) if, at the time of transfer, a Form S-8 registration statement under the Securities Act is available
for the issuance of shares by the Company upon the exercise of such transferred option, or (ii) the transfer is to your employer at the time of transfer or an affiliate of your employer at the time of transfer. Any such transfer is subject to
such limits as the Board may establish, and subject to the transferee agreeing to remain subject to all the terms and conditions applicable to your option prior to such transfer. The forgoing right to transfer your option shall apply to the right to
consent to amendments to the Stock Option Agreement for such option. In addition, until you transfers the option, you may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company, designate a third
party who, in the event of your death, shall thereafter be entitled to exercise your option. 
 9. CHANGE
IN CONTROL. 
 (a) In the event that you are required to resign your position as a Non-Employee
Director as a condition of a Change in Control or you are removed from your position as a Non-Employee Director in connection with a Change in Control, your option shall become fully vested and exercisable immediately prior to the effectiveness of
such resignation or removal (and contingent upon the effectiveness of such Change in Control). 
 (b) If any payment or benefit you
would receive pursuant to a Change in Control from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this
sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest
portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable
federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some
portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in a manner necessary to
provide you with the greatest economic benefit. If more than one manner of reduction of payments or benefits necessary to arrive at the Reduced Amount yields the greatest economic benefit, the payments and benefits shall be reduced pro rata.

  
 3. 

 (c) The accounting firm engaged by the Company for general tax purposes as of the day
prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control,
the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. 

(d) The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting
documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by you or the Company) or such other time as requested by you or the Company. If the
accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish you and the Company with an opinion reasonably acceptable to you that no Excise Tax
will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company. 

10. OPTION NOT A SERVICE CONTRACT. Your option is not an
employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for
the Company or an Affiliate. 
 11. WITHHOLDING OBLIGATIONS. 

(a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of
your option. 
 (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any
applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined
by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting). If the date of determination of any tax withholding
obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering
the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the 

  
 4. 

 
determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully
vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole
responsibility. 
 (c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate
are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common
Stock from any escrow provided for herein unless such obligations are satisfied. 
 12. NOTICES. Any notices provided
for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage
prepaid, addressed to you at the last address you provided to the Company. 
 13. GOVERNING PLAN
DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and 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 your option and those of the Plan, the provisions of the Plan shall control.

2014 EQUITY INCENTIVE PLAN 

NON-EMPLOYEE DIRECTOR RESTRICTED STOCK UNIT
AWARD AGREEMENT 
 Pursuant to the Restricted Stock Unit Grant Notice (“Grant
Notice”) and this Non-Employee Director Restricted Stock Unit Award Agreement (“Agreement”), XenoPort, Inc. (the “Company”) has awarded you a Restricted Stock Unit Award pursuant to
Section 6(b) of the Company’s 2014 Equity Incentive Plan (the “Plan”) for the number of Stock Units as indicated in the Grant Notice (collectively, the “Award”). Defined terms not explicitly
defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan. Subject to adjustment and the terms and conditions as provided herein and in the Plan, each Stock Unit shall represent the right to receive one
(1) share of Common Stock. 
 The details of your Award, in addition to those set forth in the Grant Notice, are as follows. 

1. NUMBER OF STOCK UNITS AND SHARES
OF COMMON STOCK. The number of Stock Units in your Award is set forth in the Grant Notice. 

(a) The number of Stock Units subject to your Award and the number of shares of Common Stock deliverable with respect to such Stock
Units may be adjusted from time to time for Capitalization Adjustments as described in the Plan. You shall receive no benefit or adjustment to your Award with respect to any cash dividend or other distribution that does not result in a
Capitalization Adjustment pursuant to the Plan; provided, however, that this sentence shall not apply with respect to any shares of Common Stock that are delivered to you in connection with your Award after such shares have been delivered to
you. 
 (b) Any additional Stock Units, shares of Common Stock, cash or other property that becomes subject to the Award pursuant to
this Section 1 shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Stock Units and Common Stock covered by your
Award. 
 (c) Notwithstanding the provisions of this Section 1, no fractional Stock Units or rights for fractional shares of
Common Stock shall be created pursuant to this Section 1. The Board shall, in its discretion, determine an equivalent benefit for any fractional Stock Units or fractional shares that might be created by the adjustments referred to in this
Section 1. 
 2. VESTING. The Stock Units shall vest, if at all, as provided in the Vesting
Schedule set forth in your Grant Notice and the Plan, provided that vesting shall cease upon the termination of your Continuous Service. 

 3. DELIVERY OF SHARES OF
COMMON STOCK.  
 (a) Subject to the provisions of this Agreement and the
Plan, in the event one or more Stock Units vests, the Company shall deliver to you one (1) share of Common Stock for each Stock Unit that vests on the applicable vesting date. However, if a scheduled delivery date falls on a date that is not a
business day, such delivery date shall instead fall on the next following business day. 
 (b) The form of such delivery
(e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company. 
 4.
PAYMENT BY YOU. This Award was granted in consideration of your services for the Company. Subject to Section 10 below, except as otherwise provided in the Grant Notice, you will
not be required to make any payment to the Company (other than your past and future services for the Company) with respect to your receipt of the Award, vesting of the Stock Units, or the delivery of the shares of Common Stock underlying the Stock
Units. 
 5. SECURITIES LAW COMPLIANCE. You may not be issued any Common
Stock under your Award unless either (i) the shares of Common Stock are then registered under the Securities Act of 1933, as amended (the “Securities Act”) or (ii) the Company has determined that such issuance would
be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt
would not be in material compliance with such laws and regulations. 
 6. RESTRICTIVE LEGENDS. The
Common Stock issued under your Award shall be endorsed with appropriate legends, if any, determined by the Company. 
 7.
TRANSFER RESTRICTIONS. Prior to the time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of the shares in respect of your Award. For example, you may
not use shares that may be issued in respect of your Stock Units as security for a loan, nor may you transfer, pledge, sell or otherwise dispose of such shares. This restriction on transfer will lapse upon delivery to you of shares in respect of
your vested Stock Units. Your Award is not transferable, except by will or by the laws of descent and distribution. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate
a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of Common Stock to which you were entitled at the time of your death pursuant to this Agreement. 

8. AWARD NOT A SERVICE CONTRACT. Your Award
is not an employment or service contract, and nothing in your Award shall be deemed to create in any way whatsoever any obligation on your part to continue in the service of the Company or any Affiliate, or on the part of the Company or any
Affiliate to continue such service. In addition, nothing in your Award shall obligate the Company or any Affiliate, their respective stockholders, boards of directors or employees to continue any relationship that you might have as an Employee or
Consultant of the Company or any Affiliate. 
 9. UNSECURED OBLIGATION. Your Award is
unfunded, and even as to any Stock Units that vest, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue Common Stock pursuant to this Agreement. You shall not have voting or
any other rights as a stockholder of the Company with respect to the Common 

 
Stock acquired pursuant to this Agreement until such Common Stock is issued to you pursuant to Section 3 of this Agreement. Upon such issuance, you will obtain full voting and other rights
as a stockholder of the Company with respect to the Common Stock so issued. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship
between you and the Company or any other person. 
 10. WITHHOLDING OBLIGATIONS. 

(a) On or before the time you receive a distribution of Common Stock pursuant to your Award, or at any time thereafter as requested by
the Company, you hereby authorize any required withholding from the Common Stock issuable to you and otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state, local and foreign income and employment tax
withholding obligations of the Company or any Affiliate which arise in connection with your Award (the “Withholding Taxes”). If specified in your Grant Notice, you may direct the Company to withhold shares of Common Stock
with a Fair Market Value (measured as of the date shares of Common Stock are delivered pursuant to Section 3) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld
shall not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable
to supplemental taxable income. 
 (b) Unless the tax withholding obligations of the Company and/or any Affiliate are satisfied, the
Company shall have no obligation to deliver to you any Common Stock. 
 (c) In the event the Company’s obligation to withhold
arises prior to the delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to
indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount. 
 11. CHANGE
IN CONTROL. In the event that you are required to resign your position as a Non-Employee Director as a condition of a Change in Control or you are removed from your position as a Non-Employee Director in connection
with a Change in Control, the vesting of your Award shall be accelerated in full. 
 12. BEST
AFTER-TAX PROVISION. 
 (a) If any payment or benefit you would receive pursuant to a
Change in Control from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the
excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that
would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after 

 
taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on
an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so
that the Payment equals the Reduced Amount, reduction shall occur in a manner necessary to provide you with the greatest economic benefit. If more than one manner of reduction of payments or benefits necessary to arrive at the Reduced Amount yields
the greatest economic benefit, the payments and benefits shall be reduced pro rata. 
 (b) The accounting firm engaged by the
Company for general tax purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual,
entity or group effecting the Change in Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such
accounting firm required to be made hereunder. 
 (c) The accounting firm engaged to make the determinations hereunder shall provide
its calculations, together with detailed supporting documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by you or the Company) or such
other time as requested by you or the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish you and the Company with an
opinion reasonably acceptable to you that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company. 

13. NOTICES. Any notices provided for in your Award or the Plan shall be given in writing to each of the
other parties hereto and shall be deemed effectively given on the earlier of (i) the date of personal delivery, including delivery by express courier, or (ii) the date that is five (5) days after deposit in the United States Post
Office (whether or not actually received by the addressee), by registered or certified mail with postage and fees prepaid, addressed at the following addresses, or at such other address(es) as a party may designate by ten (10) days’

interpretation made in good faith with respect to the Plan or this Agreement.
