 ATTACHMENT I 

OPTION AGREEMENT 
  

 ATARA BIOTHERAPEUTICS, INC. 

2014 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
Atara Biotherapeutics, 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. The option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). If there is any conflict between the
terms in this Option Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but defined in the Plan will have the same definitions as in the Plan. 

The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1. VESTING. Subject to the provisions contained herein, your option will vest as provided in your Grant Notice. 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 in your Grant Notice will be adjusted for Capitalization Adjustments. 

3. EXERCISE RESTRICTION FOR NON-EXEMPT
EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided
in the Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant, even if you have already been an employee for more than six (6) months. Consistent with
the provisions of the Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in which
your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your “retirement” (as defined in the Company’s benefit plans).  

4. EXERCISE PRIOR TO VESTING (“EARLY
EXERCISE”). If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise Permitted”) and subject to the provisions of your option, you may elect at any
time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your option; provided, however,
that: 

  
 4 

 (a) a partial exercise of your option will be deemed to cover first vested shares of
Common Stock and then the earliest vesting installment of unvested shares of Common Stock; 
 (b) any shares of Common Stock so
purchased from installments that have not vested as of the date of exercise will be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

(c) you will enter into the Company’s form of Early Exercise Stock Purchase Agreement with a vesting schedule that will result in
the same vesting as if no early exercise had occurred; and 
 (d) if your option is an Incentive Stock Option, then, to the extent
that the aggregate Fair Market Value (determined at the Date of Grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year
(under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) will be treated as Nonstatutory Stock
Options. 
 5. METHOD OF PAYMENT. You must pay the full amount of the exercise price for
the shares you wish to exercise. You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or in any other manner permitted by your Grant Notice, which may include one or more of
the following: 
 (a) Provided that at the time of exercise the Common Stock is publicly traded, 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. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”. 

(b) Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company (either by actual delivery or
attestation) of already-owned shares of Common Stock 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, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. You may not exercise your option by
delivery to the Company of Common Stock if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

(c) If this option is a Nonstatutory Stock Option, subject to the consent of the Company at the time of exercise, by a “net
exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise
price. You must pay any remaining balance of the aggregate exercise price 

  
 5 

 
not satisfied by the “net exercise” in cash or other permitted form of payment. Shares of Common Stock will no longer be outstanding under your option and will not be exercisable
thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding obligations.

 6. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock. 

7. SECURITIES LAW COMPLIANCE. In no event may you exercise your option unless the shares
of Common Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the registration requirements of the
Securities Act. The exercise of your option also must comply with all 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 (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

8. TERM. You may not exercise your option before the Date of Grant or after the expiration of the option’s term.
The term of your option expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following: 

(a) immediately upon the termination of your Continuous Service for Cause; 

(b) three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability or your
death (except as otherwise provided in Section 8(d) below); provided, however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above
relating to “Securities Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous
Service; provided further, if during any part of such three (3) month period, the sale of any Common Stock received upon exercise of your option would violate the Company’s insider trading policy, then your option will not expire
until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service during which the sale of the Common Stock received upon exercise of your
option would not be in violation of the Company’s insider trading policy. Notwithstanding the foregoing, if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant,
and (iii) you have vested in a portion of your option at the time of your termination of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date
of Grant, and (B) the date that is three (3) months after the termination of your Continuous Service, and (y) the Expiration Date; 

(c) twelve (12) months after the termination of your Continuous Service due to your Disability (except as otherwise provided in
Section 8(d)) below; 

  
 6 

 (d) eighteen (18) months after your death if you die either during your Continuous
Service or within three (3) months after your Continuous Service terminates for any reason other than Cause; 
 (e) the
Expiration Date indicated in your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death
or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide
services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates.

 9. 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 (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price and any applicable
withholding taxes to the Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require. 

(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. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the Date of Grant or within one (1) year after such shares of
Common Stock are transferred upon exercise of your option. 
 (d) By exercising your option you agree that you will not sell, dispose
of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to any shares of Common Stock or other securities of the Company held
by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed 

  
 7 

 
under the Securities Act or such longer period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2711 or NYSE Member Rule 472 or any successor or similar
rules or regulation (the “Lock-Up Period”); provided, however, that nothing contained in this section will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You
further agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the intent of this provision or that are necessary to give further effect to this provision. In
order to enforce this covenant, the Company may impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. You also agree that any transferee of any shares of Common Stock (or other securities) of the
Company held by you will be bound by this Section 9(d). The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d) and will have the right, power and authority to enforce the provisions hereof
as though they were a party hereto. 
 10. TRANSFERABILITY. Except as otherwise provided in this Section 10, your
option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. 

(a) Certain Trusts. Upon receiving written permission from the Board or its duly authorized designee, you may transfer your option to a
trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust. You and the trustee must enter into transfer and other agreements required by
the Company. 
 (b) Domestic Relations Orders. Upon receiving written permission from the Board or its duly authorized designee, and
provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of a domestic relations order, official marital settlement agreement or other
divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this option with
the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement agreement. If this option is an Incentive
Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 
 (c) Beneficiary
Designation. Upon receiving written permission from the Board or its duly authorized designee, you may, by delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option
exercises, designate a third party who, on your death, will thereafter be entitled to exercise this option and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor or
administrator of your estate will be entitled to exercise this option and receive, on behalf of your estate, the Common Stock or other consideration resulting from such exercise. 

  
 8 

 11. RIGHT OF FIRST REFUSAL.
 
 (a) If at any time you propose to transfer (“Transfer”) shares of Common Stock that were acquired
under this option, then you will promptly give the Company written notice of your intention to make the Transfer (the “Transfer Notice”). The Transfer Notice shall include (i) a description of the shares to be
transferred (the “Offered Shares”), (ii) the name(s) and address(es) of the prospective transferee(s), (iii) the purchase price and form of consideration proposed to be paid for the Offered Shares and (iv) the
other material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Participant has received a firm offer from the prospective transferee(s) and in good faith believes a binding agreement
for the Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. 

(b) The Company shall have an option for a period of ten (10) days from its receipt of the Transfer Notice to elect to purchase the
Offered Shares at the same price and subject to the same material terms and conditions as described in the Transfer Notice. The Company may exercise such purchase option and purchase all or any portion of the Offered Shares by notifying you in
writing before expiration of such ten (10) day period as to the number of such shares that it wishes to purchase. If the Company gives you notice that it desires to purchase such shares, then payment for the Offered Shares shall be made by
check or wire transfer against delivery of the Offered Shares to be purchased at a time and place agreed upon between the parties, which time shall be no later than forty-five (45) days after receipt by the Company of the Transfer Notice,
unless the Transfer Notice contemplated a later closing with the prospective third party transferee(s) or unless the value of the consideration to be paid for the Offered Shares has not yet been established in accordance with the below provisions.
If the Company fails to purchase any or all of the Offered Shares by exercising the option within the ten day period provided, the remaining Offered Shares shall be subject to the following paragraphs. 

(c) Subject to the Company’s option set forth above, if at any time you propose a Transfer, then, within five (5) days after
the Company has declined to purchase all, or a portion, of the Offered Shares or the Company’s option to so purchase the Offered Shares has expired, you shall give each Company stockholder (each a “Holder”) that is
designated by the Company an “Additional Transfer Notice” that shall include all of the information and certifications required in a Transfer Notice and shall additionally identify the Offered Shares that the Company has declined to
purchase (the “Remaining Shares”) and reference the Holders’ rights of first refusal with respect to the proposed Transfer contained in this option. 

(d) Each Holder shall have an option for a period of fifteen (15) days from its receipt of the Additional Transfer Notice to elect
to purchase its respective pro rata share of the Remaining Shares at the same price and subject to the same material terms and conditions as described in the Additional Transfer Notice. Each Holder may exercise such purchase option and purchase all
or any portion of its pro rata share of the Remaining Shares (a “Participating Holder”) by notifying you and the Company in writing, before expiration of the fifteen (15)-day period as to the number of such shares that it
wishes to purchase (the “Participating Holder Notice”). Each Holder’s pro rata share of the Remaining Shares shall be a fraction of the 

  
 9 

 
Remaining Shares, the numerator of which shall be the number of shares of Common Stock (including shares of Common Stock issuable upon conversion of preferred stock) owned by such Holder on the
date of the Transfer Notice and denominator of which shall be the total number of outstanding shares of capital stock (including any securities convertible into shares of capital stock) held by all Holders on the date of the Transfer Notice. 

(e) In the event any Holder elects not to purchase its pro rata share of the Remaining Shares available pursuant to its option above
within the time period set forth therein, then you will promptly give written notice (the “Overallotment Notice”) to each Participating Holder that has elected to purchase all of its pro rata share of the Remaining Shares
(each a “Fully Participating Holder”), which notice shall set forth the number of Remaining Shares not purchased by the other Holders (the “Unsubscribed Shares”), and shall offer the Fully
Participating Holders the right to acquire the Unsubscribed Shares. Each Fully Participating Holder shall have five (5) days after its receipt of the Overallotment Notice to deliver a written notice to you (the “Participating Holders
Overallotment Notice”) of its election to purchase its pro rata share of the Unsubscribed Shares on the same terms and conditions as set forth in the Additional Transfer Notice, which such Participating Holders Overallotment Notice
shall also indicate the maximum number of the Unsubscribed Shares that such Fully Participating Holder will purchase in the event that any other Fully Participating Holder elects not to purchase its pro rata share of the Unsubscribed Shares. For the
purposes of determining a Fully Participating Holder’s pro rata share of the unsubscribed shares, the numerator shall be the same as that used in above and the denominator shall be the total number of shares of capital stock (including shares
issuable upon conversion of preferred stock) owned by all Fully Participating Holders on the date of the Transfer Notice. 
 (f) Each
Participating Holder shall be entitled to apportion Remaining Shares to be purchased among its partners and affiliates, provided that such Participating Holder notifies you of such allocation. 

(g) The Participating Holders shall effect the purchase of the Remaining Shares with payment by check or wire transfer against delivery
of the Remaining Shares to be purchased at a time and place agreed upon between the parties, which time shall be no later than sixty (60) days after receipt by the Company of the Transfer Notice, unless the Transfer Notice contemplated a later
closing with the prospective third-party transferee(s) or unless the value of the consideration to be paid for the Offered Shares has not yet been established. 

(h) Should the purchase price specified in the Transfer Notice or Additional Transfer Notice be payable in a form of consideration other
than cash or evidences of indebtedness, the Company (and the Participating Holders) shall have the right to pay such purchase price in an amount of cash equal to the fair market value of such consideration. If you and the Company (or the
Participating Holders) cannot agree on such fair market value within ten (10) days after receipt by the Company of the Transfer Notice (or receipt of the Additional Transfer Notice by the Holders), the valuation shall be made by an appraiser of
recognized standing selected by you and the Company (or a majority-in-interest of the Participating Holders) or, if the parties cannot agree on an appraiser within twenty (20) days after receipt by the Company of the Transfer Notice (or the
receipt of the Additional Transfer Notice by the Holders), each shall select an appraiser of recognized standing and those appraisers shall 

  
 10 

 
designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. The cost of such appraisal shall be shared equally by you, on the one hand, and the
Company (and, to the extent there are any, the Participating Holders, on the other hand, with that half of the cost to be borne by the Company and the Participating Holders to be apportioned on a pro rata basis based on the number of Shares each
such party has expressed an interest in purchasing. If the time for the closing of the Company’s purchase or the Participating Holders’ purchase has expired but the determination of the value of the purchase price offered by the
prospective transferee(s) has not been finalized, then such closing shall be held on or prior to the fifth business day after such valuation shall have been made pursuant to this section. 

(i) If, from time to time, there is any stock dividend, stock split or other change in the character or amount of any of the outstanding
Common Stock which is subject to the provisions of your option, then in such event any and all new, substituted or additional securities to which you are entitled by reason of your ownership of the shares of Common Stock acquired upon exercise of
your option will be immediately subject to the provisiosn of this Section 11 with the same force and effect. The Company’s right of first refusal provided in this Section 11 will expire on the first date upon which any security of the
Company is listed (or approved for listing) upon notice of issuance on a national securities exchange or quotation system (the “Listing Date”). 

12. OPTION NOT A SERVICE CONTRACT. Your option is not an
employment or service contract, and nothing in your option will 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 will 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. 
 13. WITHHOLDING OBLIGATIONS. 

(a) At the time you exercise your option, in whole or in part, and 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 “same day sale” 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) If this option is a Nonstatutory Stock Option, then upon your request and subject to approval by the Company, 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 classification of your option as a liability for
financial accounting purposes). 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

  
 11 

 
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 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 will 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, if applicable, unless such obligations are satisfied. 
 14. TAX
CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim
against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the
Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated
with the option.  
 15. NOTICES. Any notices provided for in your option or the Plan will be given in writing
(including electronically) and will 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. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the Plan by
electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 
 16. 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. If there is any conflict between the provisions of your option and those of the Plan, the provisions of the Plan will control. In addition, your option (and any compensation paid or shares issued under your option) is subject to recoupment
in accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable
law. 

  
 12 

 17. EFFECT ON OTHER EMPLOYEE
BENEFIT PLANS. The value of this option will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan sponsored
by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans. 

18. VOTING RIGHTS. You will not have voting or any other rights as a stockholder of the
Company with respect to the shares to be issued pursuant to this option until such shares are issued to you. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this option, and no
action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

19. SEVERABILITY. If all or any part of this Option Agreement or the Plan is declared by any court or
governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Option Agreement (or part of such a
Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

20. MISCELLANEOUS. 

(a) The rights and obligations of the Company under your option will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. 

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the
Company to carry out the purposes or intent of your option. 
 (c) You acknowledge and agree that you have reviewed your option in its

 ATTACHMENT I 

ATARA BIOTHERAPEUTICS, INC. 

RESTRICTED STOCK UNIT AWARD AGREEMENT 

(2014 EQUITY INCENTIVE PLAN) 

Pursuant to the Restricted Stock Unit Grant Notice (the “Grant Notice”) and this Restricted Stock Unit Award Agreement
(the “Agreement”) and in consideration of your services, Atara Biotherapeutics, Inc. (the “Company”) has awarded you a Restricted Stock Unit Award (the “Award”) under its 2014
Equity Incentive Plan (the “Plan”). The Award is granted to you effective as of the Date of Grant set forth in the Grant Notice for this Award. Defined terms not explicitly defined in this Agreement will have the same
meanings given to them in the Plan. In the event of any conflict between the terms in this Agreement and the Plan, the terms of the Plan will control. The details of the Award, in addition to those set forth in the Grant Notice and the Plan, are as
follows. 
 1. GRANT OF THE AWARD. The Award represents the right to be
issued on a future date the number of shares of the Company’s Common Stock as indicated in the Grant Notice upon the satisfaction of the terms set forth in this Agreement. Except as otherwise provided herein, you will not be required to make
any payment to the Company with respect to your receipt of the Award, the vesting of the shares or the delivery of the underlying Common Stock. 

2. VESTING. Subject to the limitations contained herein, the Award will vest, if at all, in accordance with the vesting
schedule provided in the Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. Upon such termination of your Continuous Service, the shares credited to the Account that were not vested on the date of such
termination will be forfeited at no cost to the Company and you will have no further right, title or interest in or to such underlying shares of Common Stock. 

3. NUMBER OF SHARES. 

(a) The number of units/shares subject to the Award may be adjusted from time to time for Capitalization Adjustments, as provided in
the Plan. 
 (b) Any shares, cash or other property that becomes subject to the Award pursuant to this Section 3 and
Section 7, if any, will 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 shares covered by the Award. 

(c) Notwithstanding the provisions of this Section 3, no fractional shares or rights for fractional shares of Common Stock will be
created pursuant to this Section 3. The Board will, in its discretion, determine an equivalent benefit for any fractional shares or fractional shares that might be created by the adjustments referred to in this Section 3. 

4. SECURITIES LAW AND OTHER COMPLIANCE. You may not be
issued any shares under the Award unless either (a) the shares are registered under the Securities Act; or (b) the Company has determined that such issuance would be exempt from the registration requirements

  
 1. 

 
of the Securities Act. The Award also must comply with other applicable laws and regulations governing the Award, and you will not receive such shares if the Company determines that such receipt
would not be in material compliance with such laws and regulations. 
 5. TRANSFER RESTRICTIONS. 

(a) General. Prior to the time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise
dispose of this Award or the shares issuable in respect of the Award, except as expressly provided in this Section 5. For example, you may not use shares that may be issued in respect of the Award as security for a loan. The restrictions on
transfer set forth herein will lapse upon delivery to you of shares in respect of the vested portion of the Award. 
 (b) Death. The
Award is transferable by will and by the laws of descent and distribution. In addition, upon receiving written permission from the Board or its duly authorized designee, you may, by delivering written notice to the Company, in a form provided by or
otherwise satisfactory to the Company and any broker designated by the Company to effect transactions under the Plan, designate a third party who, in the event of your death, will thereafter be entitled to receive any distribution of Common Stock or
other consideration to which you were entitled at the time of your death pursuant to this Agreement. In the absence of such a designation, your executor or administrator of your estate will be entitled to receive, on behalf of your estate, such
Common Stock or other consideration. 
 (c) Certain Trusts. Upon receiving written permission from the Board or its duly authorized
designee, you may transfer the Award to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the Award is held in the trust, provided that you and the trustee
enter into transfer and other agreements required by the Company. 
 (d) Domestic Relations Orders. Upon receiving written permission
from the Board or its duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer the Award or your right to receive the distribution of Common
Stock or other consideration thereunder, pursuant to a domestic relations order that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this Award with the
Company prior to finalizing the domestic relations order to help ensure the required information is contained within the domestic relations order. 

6. DATE OF ISSUANCE. 

(a) The Company will deliver to you a number of shares of the Company’s Common Stock equal to the number of vested shares subject
to the Award, including any additional shares received pursuant to Section 3 above that relate to those vested shares on the applicable vesting date(s). However, if a scheduled delivery date falls on a date that is not a business day, such
delivery date will instead fall on the next following business day. 
 (b) Notwithstanding the foregoing, in the event that
(i) you are subject to the Company’s policy permitting certain individuals to sell shares only during certain “window” 

  
 2. 

 
periods, in effect from time to time or you are otherwise prohibited from selling shares of the Company’s Common Stock in the public market and any shares covered by the Award are scheduled
to be delivered on a day (the “Original Distribution Date”) that does not occur during an open “window period” applicable to you, as determined by the Company in accordance with such policy, or does not occur on a
date when you are otherwise permitted to sell shares of the Company’s Common Stock on the open market, and (ii) the Company elects not to satisfy its obligations for Tax-Related Items (as defined in Section 10) by withholding shares
from your distribution, then such shares will not be delivered on such Original Distribution Date and will instead be delivered on the first business day of the next occurring open “window period” applicable to you pursuant to such policy
(regardless of whether you are still providing Continuous Service at such time) or the next business day when you are not prohibited from selling shares of the Company’s Common Stock in the open market, but in no event later than the fifteenth
(15th) day of the third calendar month of the calendar year following the calendar year in which the shares of Common Stock originally became vested. The form of such delivery (e.g., a stock certificate or electronic entry evidencing
such shares) will be determined by the Company. In all cases, the delivery of shares under this Award is intended to comply with Treasury Regulation Section 1.409A-1(b)(4) and will be construed and administered in such a manner. 

7. DIVIDENDS. You will receive no benefit or adjustment to your Restricted Stock Units with respect to any cash
dividend, stock dividend or other distribution except as provided in the Plan with respect to a Capitalization Adjustment. 
 8.
RESTRICTIVE LEGENDS. The shares issued under the Award will be endorsed with appropriate legends as determined by the Company. 

9. AWARD NOT AN EMPLOYMENT OR SERVICE
CONTRACT.  
 (a) Your Continuous Service with the Company or an Affiliate is not for any specified term
and may be terminated by you or by the Company or an Affiliate at any time, for any reason, with or without cause and with or without notice. Nothing in this Agreement (including, but not limited to, the vesting of the Award pursuant to
Section 2 or the issuance of the shares subject to the Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan will: (i) confer upon you any right to continue in the employ
of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or
condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or 

  
 3. 

 
benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company or an Affiliate of the right to terminate you at will and without regard to any future
vesting opportunity that you may have. 
 (b) By accepting this Award, you acknowledge and agree that the right to continue vesting
in the Award pursuant to Section 2 and the schedule set forth in the Grant Notice is earned only by continuing as an employee, director or consultant at the will of the Company or an Affiliate (not through the act of being hired, being granted
this Award or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a
“reorganization”). You further acknowledge and agree that such a reorganization could result in the termination of your Continuous Service, or the termination of Affiliate status of your employer and the loss of benefits
available to you under this Agreement, including but not limited to, the termination of the right to continue vesting in the Award. You further acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and the
vesting schedule set forth in the Grant Notice or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant with the
Company or an Affiliate for the term of this Agreement, for any period, or at all, and will not interfere in any way with your right or the right of the Company or an Affiliate to terminate your Continuous Service at any time, with or without cause
and with or without notice. 
 10. RESPONSIBILITY FOR TAXES. 

(a) You acknowledge that, regardless of any action taken by the Company, the ultimate liability for all income tax, social insurance,
payroll tax, fringe benefits tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you or deemed by the Company in its discretion to be an appropriate charge to you even if legally
applicable to the Company (“Tax-Related Items”) is and remains your responsibility and may exceed the amount actually withheld by the Company. 

(b) Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the
Company and/or the Employer to satisfy all Tax-Related Items. In this regard, you authorize the Company or its agent to satisfy their withholding obligations with regard to all Tax-Related Items, if any, by any of the following means or by a
combination of such means: (i) withholding from any compensation otherwise payable to you by the Company or the Employer; (ii) causing you to tender a cash payment; (iii) entering on your behalf (pursuant to this authorization without
further consent) into a “same day sale” commitment with a broker dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby you irrevocably elect to sell a portion of the
shares to be delivered under the Award to satisfy the Tax-Related Items and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Tax-Related Items directly to the Company and/or its Affiliates; or
(iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you in connection with the Award with a Fair Market Value (measured as of the date shares of Common Stock are issued pursuant to
Section 6) equal to the amount of such Tax-Related Items. Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable 

  
 4. 

 
minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case you will receive a refund of any over-withheld amount in cash and will
have no entitlement to the Common Stock equivalent. If the obligation for Tax-Related Items is satisfied by withholding in shares of Common Stock, for tax purposes, you are deemed to have been issued the full number of shares of Common Stock subject
to the vested portion of the Award, notwithstanding that a number of the shares of Common Stock are held back solely for the purpose of paying the Tax-Related Items. 

(c) Finally, you agree to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be
required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the shares or the proceeds of the sale of shares of Common Stock
if you fail to comply with your obligations in connection with the Tax-Related Items. 
 11. NO OBLIGATION
TO MINIMIZE TAXES. You acknowledge that the Company is not making representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Award,
including, but not limited to, the grant, vesting or settlement of the Award, the subsequent sale of shares of Common Stock acquired pursuant to such settlement and the receipt of any dividends and/or any dividend equivalent payments. Further, you
acknowledge that the Company does not have any duty or obligation to minimize your liability for Tax-Related Items arising from the Award and will not be liable to you for any Tax-Related Items arising in connection with the Award. 

12. NO ADVICE REGARDING GRANT. The Company is not providing any tax, legal
or financial advice, nor is the Company making any recommendations regarding your participation in the Plan, or your acquisition or sale of the underlying shares of Common Stock. You are hereby advised to consult with your own personal tax,
financial and/or legal advisors regarding the Tax-Related Items arising in connection with the Award and by accepting the Award, you have agreed that you have done so or knowingly and voluntarily declined to do so. 

13. UNSECURED OBLIGATION. The Award is unfunded, and as a holder of a vested Award, you will be
considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares pursuant to this Agreement. You will not have voting or any other rights as a stockholder of the Company with respect to the
shares to be issued pursuant to this Agreement until such shares are issued to you pursuant to Section 6 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in
this Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

14. OTHER DOCUMENTS. You hereby acknowledge receipt or the right to receive
a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s policy permitting certain individuals to sell shares
only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

  
 5. 

 15. NOTICES. Any notices provided for in the Grant Notice, this Agreement
or the Plan will be given in writing and will be deemed effectively given upon receipt or, in the case of notices delivered 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. Notwithstanding the foregoing, the Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic means or to request your consent to
participate in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an on-line or electronic system established and maintained by the Company
or another third party designated by the Company. 
 16. MISCELLANEOUS. 

(a) The rights and obligations of the Company under the Award will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. Your rights and obligations under the Award may only be assigned with the prior written consent of the Company. 

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the
Company to carry out the purposes or intent of the Award. 
 (c) You acknowledge and agree that you have reviewed the documents
provided to you in relation to the Award in their entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting the Award, and fully understand all provisions of such documents. 

(d) This Agreement will be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies
or national securities exchanges as may be required. 
 (e) All obligations of the Company under the Plan and this Agreement will be
binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 

17. GOVERNING PLAN DOCUMENT. The Award is subject to all the provisions of the Plan, the
provisions of which are hereby made a part of the Award, 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. Except as expressly provided
herein, in the event of any conflict between the provisions of the Award and those of the Plan, the provisions of the Plan will control. 

18. SEVERABILITY. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to
be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or
invalid will, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

  
 6. 

 19. EFFECT ON OTHER EMPLOYEE
BENEFIT PLANS. The value of the Award subject to this Agreement will not be included as compensation, earnings, salaries, or other similar terms used when calculating the Employee’s benefits under any employee
benefit plan sponsored by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit
plans. 
 20. AMENDMENT. This Agreement may not be modified, amended or terminated except by an instrument in writing,
signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which specifically states that it is amending this Agreement, so long as a copy of
such amendment is delivered to you, and provided that, except as otherwise expressly provided in the Plan, no such amendment adversely affecting your rights hereunder may be made without your written consent. Without limiting the foregoing, the
Board reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any
future law, regulation, ruling, or judicial decision, provided that any such change will be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided herein. 

21. COMPLIANCE WITH SECTION 409A OF THE
CODE. This Award is intended to comply with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4). Notwithstanding the
foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise deferred compensation subject to Section 409A, and if you are a “Specified Employee” (within the meaning
set forth Section 409A(a)(2)(B)(i) of the Code) as of the date of your separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)), then the issuance of any shares that would otherwise be made upon the date of
the separation from service or within the first six months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the date that is six months and one day after the date of the separation from
service, with the balance of the shares issued thereafter in accordance with the original vesting and issuance schedule set forth above, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of taxation on
you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2).

This Agreement will be deemed to be signed by you upon the signing by you of the 

Restricted Stock Unit Grant Notice to which it is attached.
