 Exhibit 10.6 

ADURO BIOTECH 
 STOCK
INCENTIVE PLAN 
 STOCK OPTION AGREEMENT 

1. Definitions. Unless otherwise defined herein, the terms defined in the Aduro BioTech Stock Incentive Plan (the “Plan”)
shall have the same defined meanings in this Stock Option Agreement. 
 2. Grant of Option. Pursuant to the terms and conditions set
forth in the Notice of Stock Option Grant attached hereto, this Agreement, and the Plan, Aduro BioTech (the “Company”) grants to the optionee named in the Notice of Stock Option Grant (“Optionee”) on the date of grant set forth
in the Notice of Stock Option Grant (“Date of Grant”) the option to purchase, at the exercise price set forth in the Notice of Stock Option Grant (“Exercise Price”), the number of Shares set forth in the Notice of Stock Option
Grant. This option is intended to be an Incentive Stock Option or a Non-Statutory Stock Option, as provided in the Notice of Stock Option Grant. 

3. Exercise of Option. Subject to the other conditions set forth in this Agreement, all or part of this option may be exercised before
its expiration or termination at the time or times set forth in the Notice of Stock Option Grant; provided, however, the Optionee shall cease vesting in this option on the Optionee’s Termination Date. In addition, in the event of a Change in
Control before the Optionee’s Termination Date, this option shall be subject to Section 6.9 of the Plan. Notwithstanding anything herein to the contrary, this option may not be exercised until the stockholders of the Company have approved
the Plan in accordance with Section 17 of the Plan. If the stockholders of the Company do not approve the Plan within the 12 months provided for in Section 17 of the Plan, then this option shall terminate as of the end of such 12-month
period without consideration. 
 4. Term of Option. This option shall terminate, and all rights to purchase Shares hereunder shall
cease, on the expiration date stated in the Notice of Stock Option Grant, or pursuant to the termination period set forth in the Notice of Stock Option Grant if sooner. 

5. Non-Transferability of Option. This option shall be non-transferable by the Optionee other than by will or by the laws of descent
and distribution, or to a revocable trust, and shall be exercisable during the lifetime of the Optionee only by the Optionee, or if this is a Non-Statutory Stock Option, also by the Optionee’s guardian or legal representative. After the death
of the Optionee, this option may be exercised before its termination by the Optionee’s legal representative, heir, or legatee, to the extent permitted in the Plan. Upon any attempt to sell, transfer, assign, pledge, hypothecate, or otherwise
dispose of this option (a “Transfer”), or of any right or privilege conferred hereby, contrary to the provisions hereof, or upon any attempted sale under any execution, attachment, or similar process upon the rights and privileges
conferred hereby, this option and the rights and privileges conferred hereby shall immediately be nullified. Until written notice of any permitted passage of rights under this option has been received by the Secretary of the Company, the Company,
for all purposes, may regard the Optionee as the holder of this option. 

  
 -1- 

 6. Method of Exercise. The rights granted under this Agreement may be exercised by the
Optionee, or by the person or persons to whom the Optionee’s rights under this Agreement shall have passed under the provisions of Section 5 hereof, by delivering to the Company in care of its Secretary at the Company’s principal
office, written notice of the number of Shares with respect to which the rights are being exercised, accompanied by this Agreement for appropriate endorsement by the Company, such investment letter as may be required by Section 13, executed
Stock Restriction Agreement described in Section 7, payment of the Exercise Price, satisfaction of all tax withholding obligations, and such other representations and agreements as may be required by the Administrator. The Exercise Price may be
paid in (i) cash; (ii) check; (iii) if approved by the Administrator, other Shares having a Fair Market Value on the date of surrender or attestation equal to the aggregate Exercise Price; (iv) consideration received by the
Company under a broker-assisted sale and remittance program acceptable to the Administrator; (v) if approved by the Administrator, the Company’s retention of so many of the Shares that would otherwise have been delivered upon exercise of
the Option as have a Fair Market Value on the exercise date equal to the aggregate Exercise Price of all Shares as to which the Option is being exercised, in which case the Option shall be surrendered and cancelled as to such Shares; or
(vi) any combination of the foregoing methods of payment. 
 7. Stock Restriction Agreement. Notwithstanding any other provision
of this Agreement to the contrary, the initial exercise of this option shall be conditioned upon the execution and delivery by the Optionee and, if applicable, his or her spouse, of a Stock Restriction Agreement (in the form attached hereto as
Exhibit A). The certificates evidencing the Shares issued to the Optionee hereunder shall bear the legend required by the Stock Restriction Agreement. This provision may be waived by the Company in writing and shall terminate when the Common
Stock becomes publicly traded. 
 8. Regulatory Compliance. The issue and sale of Common Stock pursuant to this Agreement shall be
subject to full compliance with all then applicable requirements of law and the requirements of any stock exchange or interdealer quotation system upon which the Common Stock may be listed or traded. 

9. Legends. The certificates evidencing the Common Stock issued upon exercise of this option, if any, shall bear the following legend,
if applicable, at the time of exercise: 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, OR UNDER THE APPLICABLE SECURITIES LAWS OF ANY STATE AND MAY BE OFFERED AND SOLD ONLY IF REGISTERED PURSUANT TO THE PROVISIONS OF SUCH ACT OR SUCH LAWS OR IF AN EXEMPTION FROM REGISTRATION IS AVAILABLE. 

10. Modification and Termination. The rights of the Optionee are subject to modification and termination in certain events, as provided
in the Plan. 
 11. Withholding Tax. As a condition to the exercise of this option, the Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, 

  
 -2- 

 
state, and local income and employment tax withholding requirements and any other tax withholding requirements that may arise in connection with such exercise. The Optionee shall also make such
arrangements as the Administrator may require for the satisfaction of any federal, state, and local income and employment tax withholding requirements and any other tax withholding requirements that may arise in connection with the disposition of
Shares purchased by exercising this option. The Optionee shall pay to the Company an amount equal to the withholding amount (or the Company may withhold such amount from the Optionee’s salary) in cash or check. At the Administrator’s
election, the Optionee may pay the withholding amount with Shares (including previously vested Optioned Stock) or by the Company’s withholding Shares that otherwise would be issued to the Optionee pursuant to exercise of the Option, provided
that payment in Shares shall be limited to the withholding amount calculated using the minimum statutory withholding rates interpreted in accordance with applicable accounting requirements; or by consideration received by the Company under a
broker-assisted sale and remittance program acceptable to the Administrator. 
 12. Holder of Shares. Neither the Optionee nor the
Optionee’s legal representative, legatee, or distributee shall be or be deemed a holder of any Shares subject to this option unless and until such Shares have been issued (as evidenced by the appropriate entry on the books of the books of the
Company or of the Company’s duly authorized transfer agent) and such person has been issued a certificate or certificates therefor. No adjustment will be made for dividends or other rights for which the record date precedes the date such stock
certificate or certificates are so issued. 
 13. Investment Covenant. The Optionee represents and agrees that if the Optionee
exercises this option in whole or in part at a time when there is not in effect under the Securities Act, a registration statement relating to the Shares issuable upon exercise hereof and there is not available for delivery a prospectus meeting the
requirements of Section 10(a)(3) of such Act, (i) the Optionee will acquire the Shares upon such exercise for the purpose of investment and not with a view to the distribution thereof; (ii) if requested by the Company, upon such
exercise of this option, the Optionee will furnish to the Company an investment letter in form acceptable to it; (iii) if requested by the Company, before selling or offering for sale any such Shares, the Optionee will furnish the Company with
an opinion of counsel satisfactory to it to the effect that such sale may lawfully be made and will furnish it with such certificates as to factual matters as it may reasonably request; and (iv) certificates representing such shares may be
marked with an appropriate legend describing such conditions precedent to sale or transfer. Any person or persons entitled to exercise this option under the provision of Section 5 hereof shall furnish to the Company letters, opinions, and
certificates to the same effect as would otherwise be required of the Optionee. 
 14. Nondisclosure. The grant and terms of this
option are confidential and may not be disclosed by Optionee to any other person, including other employees of the Company and other participants in the Plan, without the express written consent of the Company’s President. Notwithstanding the
foregoing, the Optionee may disclose the grant and terms of this option to the Optionee’s family member, financial advisor, and attorney. Any breach of this provision will be deemed a material breach of this Agreement. 

  
 -3- 

 15. Governing Law. This Agreement shall be governed by and interpreted in accordance with
the internal laws of the State of California. 
 16. Successors. This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their legal representatives, heirs, and permitted successors and assigns. 
 17. Plan. This Agreement is subject
to all of the terms and provisions of the Plan, receipt of a copy of which is hereby acknowledged by the Optionee. The Optionee further acknowledges receipt of a copy of the Stock Restriction Agreement. The Optionee hereby agrees to accept as
binding, conclusive, and final all decisions and interpretations of the Administrator upon any questions arising under the Plan, this Agreement, and Notice of Stock Option Grant. 

18. Rights to Future Employment. This option does not confer upon the Optionee any right to continue in the Service of the Company or
any Affiliate, nor does it limit the right of the Company to terminate the Service of the Optionee at any time. 
 19. Market
Standoff. In connection with any underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, the
Optionee shall not directly or indirectly sell, make any short sale of, loan, hypothecate, pledge, offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the sale of, or otherwise dispose of
or transfer, or agree to engage in any of the foregoing transactions with respect to, any Shares acquired under this Agreement without the prior written consent of the Company or its underwriters. Such restriction (the “Market Standoff”)
shall be in effect for such period following the date of the final prospectus for the offering as may be requested by the Company or such underwriters. In no event, however, shall such period exceed 180 days. In the event of the declaration of a
stock dividend, a spin-off, a stock split, an adjustment in conversion ratio, a recapitalization, or a similar transaction affecting the Company’s outstanding securities without receipt of consideration, any new, substituted, or additional
securities that are by reason of such transaction distributed with respect to any Shares subject to the Market Standoff, or into which such Shares thereby become convertible, shall immediately be subject to the Market Standoff. In order to enforce
the Market Standoff, the Company may impose stop-transfer instructions with respect to the Shares acquired under this Agreement until the end of the applicable standoff period. The Company’s underwriters shall be beneficiaries of the agreement
set forth in this Section. This Section shall not apply to Shares registered in the public offering under the Securities Act. 
 20.
Entire Agreement. The Notice of Stock Option Grant, this Agreement, the Plan, and the Stock Restriction Agreement constitute the entire contract between the parties hereto with regard to the subject matter hereof. They supersede any other
agreements, representations, or understandings (whether oral or written and whether express or implied) that relate to the subject matter hereof.

 Exhibit 10.11 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of
                                        
between Aduro BioTech, Inc., a Delaware corporation (the “Company”), and
                                        
(“Indemnitee”). 
 WITNESSETH THAT: 

WHEREAS, highly competent persons have become more reluctant to serve corporations as directors and officers or in
other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the
corporation; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined
that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities.
Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may
be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and
time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The By-laws and Certificate of Incorporation of the Company require indemnification
of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The By-laws and Certificate of Incorporation and the DGCL
expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect
to indemnification; 
 WHEREAS, the uncertainties relating to such insurance and to indemnification have
increased the difficulty of attracting and retaining such persons; 
 WHEREAS, the Board has determined that
the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such
protection in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to
obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so
indemnified; 

  
 -1- 

 WHEREAS, this Agreement is a supplement to and in furtherance of the
By-laws and Certificate of Incorporation of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

WHEREAS, Indemnitee does not regard the protection available under the Company’s By-laws and Certificate of
Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as an officer and/or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to
serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and 

WHEREAS, Indemnitee may be a representative of or affiliated with a venture capital fund (together with any affiliated
venture capital funds and the general partners, managing members or other control persons and/or any affiliated management companies, the “VC Funds,” and each, individually, a “VC Fund”), and, if so, has certain
rights to indemnification and/or insurance provided by the VC Funds, which Indemnitee and the VC Fund intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement
and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board. 

NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as an officer and/or director from and
after the date hereof, the parties hereto agree as follows: 
 1. Indemnity of Indemnitee. The Company hereby
agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of
indemnification provided in this Section l(a) if, by reason of such person’s Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined)
other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually
and reasonably incurred by such person, or on such person’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification
provided in this Section 1(b) if, by reason of such person’s Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee 

  
 -2- 

 
acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so
provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of
Chancery of the State of Delaware shall determine that such indemnification may be made. 
 (c) Indemnification for
Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any
Proceeding, he shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly
successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by him or on his behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or
without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 2. Additional
Indemnity. 
 (a) Indemnification of Indemnitee. In addition to, and without regard to any limitations on, the
indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf if, by reason of his Corporate Status, he is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without
limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be
obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful. 

(b) Indemnification of Venture Capital Funds. If (i) Indemnitee is or was a representative of or affiliated with
one or more VC Funds that has invested in the Company, (ii) the VC Fund is, or is threatened to be made, a party to or a participant in any Fund Proceeding (as hereinafter defined), and (iii) the VC Fund’s involvement in the Fund
Proceeding arises out of facts or circumstances that are the same or substantially similar to the facts and circumstances that form the basis of claims that have been or could be brought against the Indemnitee in a Proceeding, regardless of whether
the legal basis of the claims against the Indemnitee and the VC Fund are the same or similar, then the VC Fund shall be entitled to all of the indemnification rights and remedies under this Agreement pursuant to this Agreement as if the VC Fund were
the Indemnitee. 

  
 -3- 

 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any
threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any
judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter
into any settlement of any action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims
asserted against Indemnitee. 
 (b) Without diminishing or impairing the obligations of the Company set forth in the
preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with
Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in
proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one
hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform
to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or
proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law may require to
be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and
Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and
the degree to which their conduct is active or passive. 
 (c) The Company hereby agrees to fully indemnify and hold
Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d) To the fullest extent permissible under applicable law and without diminishing or impairing the obligations of the Company
set forth in the preceding subparagraphs of this Section 3, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the
amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in 

  
 -4- 

 
connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in
order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors,
officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 4.
Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any
Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company shall advance all
Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting
such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by
a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this
Section 5 shall be unsecured and interest free and not conditioned on Indemnitee’s ability to repay such advances. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement
to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event
of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a) To obtain
indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine
whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification.
Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the
extent that, such failure actually and materially prejudices the interests of the Company. 
 (b) Upon written request by
Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which
shall be at the election of the Board: (1) by a majority vote of the Disinterested Directors (as hereinafter

defined), even though less than a quorum, (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum,
(3) if there are no Disinterested Directors or if the Disinterested Directors so direct, by Independent Counsel (as hereinafter defined) in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, or (4) if so
directed by the Board, by the stockholders of the Company. 
 (c) If the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within 10
days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so
selected does not meet the requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and
timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a
court has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and
not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s
selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the
person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant
to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making
such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither
the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has
met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a
presumption that Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee shall be deemed to have acted
in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the

  
 -6- 

 
Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified
public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to
Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times
acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing
evidence. 
 (f) If the person, persons or entity empowered or selected under Section 6 to determine whether
Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have
been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in
connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional
thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and
provided, further, that the foregoing provisions of this Section 6(g) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this
Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board of Directors or the Disinterested Directors, if appropriate, resolve to submit such determination to the
stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen
(15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s
entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available
to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board of Directors or stockholder of the Company shall act reasonably and in good faith in making a determination regarding the Indemnitee’s
entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the
Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

  
 -7- 

 (h) The Company acknowledges that a settlement or other disposition short of
final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse
judgment against Indemnitee (including, without limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise
in such action, suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(i) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction,
or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in
good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. 

7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to
Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten (10) days after receipt by the
Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made
pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such
indemnification. Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall
not oppose Indemnitee’s right to seek any such adjudication. 
 (b) In the event that a determination shall have been
made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the
merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 
 (c)
If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this
Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to 

  
 -8- 

 
make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of his rights under,
or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all
expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by him in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, advancement of expenses or insurance recovery. The Company irrevocably authorizes the Indemnitee from time to time to retain counsel of Indemnitee’s choice, at the expense of the Company to the extent provided
hereunder or under applicable law, to advise and represent Indemnitee in connection with any such judicial adjudication or recovery, including without limitation the initiation or defense of any litigation or other legal action, whether by or
against the Company or any director, officer, stockholder or other person affiliated with the Company. Notwithstanding any existing or prior attorney-client relationship between the Company and such counsel, the Company irrevocably consents to
Indemnitee’s entering into an attorney-client relationship with such counsel, and in that connection the Company and Indemnitee agree that a confidential relationship shall exist between Indemnitee and such counsel. 

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7
that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any
and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by
Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company,
regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under
this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 8. Non-Exclusivity;
Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 
 (a) The rights of indemnification as provided
by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the By-laws, any agreement, a vote of stockholders, a resolution of directors
or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his
Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in 

  
 -9- 

 
the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of Incorporation, By-laws and this Agreement, it is the
intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and
remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an
insurance policy or policies providing liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that
such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary
under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as
a result of such proceeding in accordance with the terms of such policies. 
 (c) The Company hereby acknowledges that
Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more VC Funds and certain of its or their affiliates (collectively, the “Fund Indemnitors”). If the indemnity has
such rights, the Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same
expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and
amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to
any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other
recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall
affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree
that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(c). 
 (d) Except as provided
in paragraph (c) above, in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee (other than against the Fund Indemnitors), who shall execute

  
 -10- 

 
all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(e) Except as provided in paragraph (c) above, the Company shall not be liable under this Agreement to make any payment
of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(f) Except as provided in paragraph (c) above, the Company’s obligation to indemnify or advance Expenses hereunder
to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount
Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be
obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for an
accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of
state statutory law or common law; or 
 (b) in connection with any Proceeding (or any part of any Proceeding) initiated by
Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any
Proceeding) prior to its initiation, (ii) the Proceeding is initiated by Indemnitee pursuant to Indemnitee’s rights under Section 7 of this Agreement, or (iii) the Company provides the indemnification, in its sole discretion,
pursuant to the powers vested in the Company under applicable law. 
 10. Duration of Agreement. All agreements and
obligations of the Company contained herein shall continue during the period the Indemnitee is an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise) and for a period of five (5) years thereafter and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under
Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement. This
Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially
all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Security. To the extent requested by Indemnitee and approved by the Board, the Company may at any time and from
time to time provide security to Indemnitee for 

  
 -11- 

 
the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or
released without the prior written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on
it hereby in order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 

13. Definitions. For purposes of this Agreement: 

(a) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or
fiduciary of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving at the express written request of the Company. 

(b) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding
in respect of which indemnification is sought by Indemnitee. 
 (c) “Enterprise” shall mean the Company and
any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary. 

(d) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs,
fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with
prosecuting, defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding. Expenses also shall
include Expenses incurred in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement,
including without limitation the premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount
of judgments or fines against Indemnitee. 
 (e) “Fund Proceeding” means any threatened, pending or
completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative 

  
 -12- 

 
hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in
which a VC Fund was, is or will be involved as a party or otherwise. 
 (f) “Independent Counsel” means a
law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such
party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the
Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all
Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 

(g) “Proceeding” includes any threatened, pending or completed action, suit, arbitration, alternate dispute
resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or
investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was an officer or director of the Company, by reason of any action taken by him or of any inaction on his part while
acting as an officer or director of the Company, or by reason of the fact that he is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other
Enterprise; in each case whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this
Agreement, but excluding one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce his rights under this Agreement. 

14. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or
enforceability of any other provision. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision
hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding
unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver. 

  
 -13- 

 16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company
in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The
failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company. 

17. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and
shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the

proceeding arising out of or in connection with this Agreement shall be brought only in the Chancery Court of the State of Delaware (the “Delaware Court”), and not in any other state or federal court in the United States of America
