 Exhibit 10.1 

CONKWEST, INC. 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is dated as of _____ __, ___ and is between
Conkwest, Inc., a Delaware corporation (the “Company”), and _________ (“Indemnitee”). 

RECITALS 

A.     The Company desires to attract and retain the services of highly qualified individuals such as
Indemnitee to serve as officers, directors or employees of the Company 
 B.     Individuals are
reluctant to serve as directors or officers of corporations or in certain other capacities unless they are provided with adequate protection through insurance or indemnification against the risks of claims and actions against them arising out of
such service. 
 C.     Indemnitee does not regard the protection currently provided by applicable law,
the Company’s governing documents and any insurance as adequate under the present circumstances, and Indemnitee may not be willing to serve as a director or officer without additional protection. 

D.     In order to induce Indemnitee to continue to provide services to the Company, it is reasonable,
prudent and necessary for the Company and its stockholders to contractually obligate itself to indemnify, and to advance expenses on behalf of, Indemnitee as permitted by applicable law in order that Indemnitee will serve or continue to serve the
Company free from undue concern that Indemnitee will not be so indemnified. 
 E.     This Agreement is
a supplement to and in furtherance of the indemnification provided in the Company’s certificate of incorporation and bylaws, and any resolutions adopted pursuant thereto, and this Agreement shall not be deemed a substitute therefor, nor shall
this Agreement be deemed to limit, diminish or abrogate any rights of Indemnitee thereunder. 
 The parties therefore agree
as follows: 
 1.     Definitions. 

(a)     A “Change in Control” shall be deemed to occur upon the earliest to occur
after the date of this Agreement of any of the following events: 
 (i)     Acquisition of
Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the
Company’s then outstanding securities; 
 (ii)     Change in Board
Composition. During any period of two consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Company’s board of directors, and any new directors
(other than a director designated by a person who has entered into an agreement with the Company to  







 
effect a transaction described in Sections 1(a)(i), 1(a)(iii) or 1(a)(iv)) whose election by the board of directors or nomination for election by the Company’s stockholders was approved
by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease
for any reason to constitute at least a majority of the members of the Company’s board of directors; 

(iii)     Corporate Transactions. The effective date of a merger or consolidation of the
Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or
by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and with the power to elect at
least a majority of the board of directors or other governing body of such surviving entity; 

(iv)     Liquidation. The approval by the stockholders of the Company of a complete
liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; and

response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended, whether or not the Company is then subject

following meanings: 
 (1)     “Person” shall have the meaning as

2.     Indemnity in Third-Party Proceedings. The Company
shall indemnify Indemnitee in accordance with the provisions of this Section 2 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a
judgment in its favor. Pursuant to this Section 2, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by
Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company

3.     Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify

of any claim, issue or matter as to which Indemnitee shall have been adjudged by a court of competent jurisdiction to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery or any court in which the Proceeding
was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such expenses as the Delaware Court of
Chancery or such other court shall deem proper.

the merits or otherwise, in 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 Indemnitee or on Indemnitee’s behalf in
connection with (a) each successfully resolved claim, issue or matter, and (b) any claim, issue or matter related to any such successfully resolved claim, issue or matter. For purposes of this section, the termination of any claim, issue

 -4- 








 5.     Indemnification for Expenses of a Witness. To
the extent that Indemnitee is, by reason of his or her Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified to the extent permitted by applicable law against all Expenses actually and

 6.    
Additional Indemnification. 
 (a)     Notwithstanding any limitation in Sections 2, 3 or
4, the Company shall indemnify Indemnitee to the fullest extent permitted by applicable law if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding (including a Proceeding by or in the right of the Company to
procure a judgment in its favor) against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his or her behalf in connection with the Proceeding or any claim, issue or matter therein.

 (b)     For purposes of Section 6(a), the meaning of the phrase “to the fullest
extent permitted by applicable law” shall include, but not be limited to: 
 (i)     the
fullest extent permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 

(ii)     the fullest extent authorized or permitted by any amendments to or replacements of the DGCL
adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

7.     Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be
obligated under this Agreement to make any indemnity in connection with any Proceeding (or any part of any Proceeding): 

(a)     for which payment has actually been made to or on behalf of Indemnitee under any insurance policy
or indemnity provision, except with respect to any excess beyond the amount paid; 
 (b)     for an
accounting or disgorgement of profits pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law, if Indemnitee is held liable therefor; 

(c)     for any reimbursement of the Company by Indemnitee of any bonus or other incentive-based or
equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Securities Exchange Act of 1934, as amended (including any such reimbursements that arise from an
accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment
to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act), if Indemnitee is held liable therefor; or 

  
 -5- 








 (d)     initiated by Indemnitee and not by way of defense,
including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees, agents or other indemnitees, unless (i) the Company’s board of directors authorized the Proceeding
(or the relevant part of the Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, (iii) otherwise authorized in
Section 12(d) or (iv) otherwise required by applicable law. 
 8.     Advances of
Expenses. The Company shall advance the Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding prior to its final resolution, and such advancement shall be made as soon as reasonably practicable, but in any event no
later than 30 days, after the receipt by the Company of a written statement or statements requesting such advances from time to time (which shall include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices
in connection with legal services, any references to legal work performed or to expenditure made that would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the invoice. Advances shall be unsecured and
interest free and made without regard to Indemnitee’s ability to repay such advances. The Company’s obligation to provide an advancement of expenses is subject to the following conditions: (a) if the proceeding arose in connection
with Indemnitee’s service as a director or officer, as applicable, then the Indemnitee or his or her representative shall have executed and delivered to the Company an undertaking, which need not be secured and shall be accepted without
reference to Indemnitee’s financial ability to make repayment, by or on behalf of Indemnitee to repay all advances if and to the extent that it shall ultimately be determined by a final, non-appealable decision rendered by a court having
jurisdiction over the parties and the question that Indemnitee is not entitled to be indemnified for such advances under this Agreement or otherwise; (b) Indemnitee shall give the Company such information and cooperation as it may reasonably
request and as shall be within Indemnitee’s power; and (c) Indemnitee shall furnish, upon request by the Company and if required under applicable law, a written affirmation of Indemnitee’s good faith belief that any applicable
standards of conduct have been met by Indemnitee. Indemnitee’s entitlement to such advances shall include those incurred in connection with any proceeding by Indemnitee seeking an adjudication pursuant to this Agreement. Indemnitee hereby
undertakes to repay any advance to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. 

9.     Procedures for Notification and Defense of Claim. 

(a)     Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee
intends to seek indemnification or advancement of Expenses as soon as reasonably practicable following the receipt by Indemnitee of notice thereof. The written notification to the Company shall include, in reasonable detail, a description of the
nature of the Proceeding and the facts underlying the Proceeding. The failure by Indemnitee to notify the Company will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement,
except to the extent that such failure or delay materially prejudices the Company. 

  
 -6- 








 (b)     If, at the time of the receipt of a notice of a
Proceeding pursuant to the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of the Proceeding to the insurers in accordance with the procedures
set forth in the applicable policies. The Company shall thereafter take all action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(c)     The Company will be entitled to participate in the defense of any Proceeding at its own expense.

 10.     Procedures upon Application for Indemnification. 

(a)     To obtain indemnification, Indemnitee shall submit to the Company a written request, including
therein or therewith such documentation and information as is reasonably available to Indemnitee and as is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of the
Proceeding. Any delay in providing the request will not relieve the Company from its obligations under this Agreement, except to the extent such failure is prejudicial. 

(b)     Upon written request by Indemnitee for indemnification pursuant to Section 10(a), a
determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Company’s board of directors, a copy
of which shall be delivered to Indemnitee or (ii) if a Change in Control shall not have occurred if required by applicable law (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Company’s
board of directors, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Company’s board of directors, (C) if there are no such Disinterested
Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be delivered to Indemnitee or (D) if so directed by the Company’s board of
directors, by the stockholders of the Company. If it is determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten days after such determination. Indemnitee shall cooperate with the person, persons or
entity making the 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 that is not privileged or
otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’ fees and disbursements) reasonably incurred by Indemnitee in so
cooperating with the person, persons or entity making such determination shall be borne by the Company, to the extent permitted by applicable law. 

(c)     In the event the determination of entitlement to indemnification is to be made by Independent
Counsel pursuant to Section 10(b), the Independent Counsel shall be selected as provided in this Section 10(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Company’s board of
directors, and the Company shall give written notice to Indemnitee advising him or her of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee


  
 -7- 








 
(unless Indemnitee shall request that such selection be made by the Company’s board of directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice
to the Company advising it of the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten days after such written notice of selection shall have been given, deliver to the
Company or to Indemnitee, as the case may be, 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 1 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 such written objection is so made and substantiated, the Independent Counsel so 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 the later of (i) submission by Indemnitee of a written request for indemnification pursuant to Section 10(a) hereof and (ii) the final disposition of the Proceeding, the parties have not agreed
upon an Independent Counsel, either the Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel
and 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 10(b) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a) of this Agreement, the Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). The Company shall pay the reasonable fees and expenses of any Independent Counsel. 

11.     Presumptions and Effect of Certain Proceedings. 

(a)     In making a determination with respect to entitlement to indemnification hereunder, the person,
persons or entity making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement, and the Company shall, to the fullest extent not prohibited by law, have the
burden of proof to overcome that presumption. 
 (b)     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 create a presumption that
Indemnitee did not act in good faith and in a manner which he or she 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 or her conduct was unlawful. 
 (c)     Neither the knowledge, actions nor failure to act of any
other director, officer, agent or employee of the Enterprise shall be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.

 12.     Remedies of Indemnitee. 

(a) Subject to Section 12(e), in the event that (i) a determination is made pursuant to Section 10 of this
Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 or 12(d) of this Agreement, (iii) no determination of entitlement to
indemnification shall have been made pursuant to Section 10 of this Agreement within 90 days after the receipt by the Company of the request for indemnification, (iv) payment of indemnification pursuant to this Agreement is not made
(A) within ten days after a determination has been made that Indemnitee is entitled to indemnification or (B) with respect to indemnification pursuant to Sections 4, 5 and 12(d) of this Agreement, within 30 days after receipt by the
Company of a written request therefor, or (v) the Company or any other person or entity takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed
to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of competent jurisdiction of his or her entitlement to such indemnification
or advancement of Expenses. Alternatively, Indemnitee, at his or her option, may seek an award in arbitration with respect to his or her entitlement to such indemnification or advancement of Expenses, to be conducted by a single arbitrator pursuant
to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to
commence such proceeding pursuant to this Section 12(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his or her rights under Section 4 of this
Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration in accordance with this Agreement. 

(b)     Neither (i) the failure of the Company, its board of directors, any committee or subgroup of
the board of directors, Independent Counsel or stockholders to have made a determination that indemnification of Indemnitee is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual
determination by the Company, its board of directors, any committee or subgroup of the board of directors, Independent Counsel or stockholders that Indemnitee has not met the applicable standard of conduct, shall create a presumption that Indemnitee
has or has not met the applicable standard of conduct. In the event that a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration
commenced pursuant to this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding
or arbitration commenced pursuant to this Section 12, the Company shall, to the fullest extent not prohibited by law, have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 

(c)     To the fullest extent not prohibited by law, the Company shall be precluded from asserting in any
judicial proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the
Company is bound by all the provisions of this Agreement. If a determination shall have been made pursuant to Section 10 of this 

  
 -9- 








 
Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 12,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statements not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d)     To the fullest extent not
prohibited by law, the Company shall indemnify Indemnitee against all Expenses that are incurred by Indemnitee in connection with any action for indemnification or advancement of Expenses from the Company under this Agreement or under any
directors’ and officers’ liability insurance policies maintained by the Company, unless the court (or arbitrator) finds that each material argument or defense advanced by Indemnitee in such action or arbitration was either frivolous or not
made in good faith. Further, if requested by Indemnitee, the Company shall (as soon as reasonably practicable, but in any event no later than 30 days, after receipt by the Company of a written request therefor) advance such Expenses to Indemnitee,
subject to the provisions of Section 8, subject to Indemnitee’s agreement to repay the sums advanced if the court (or arbitrator) finds that each material argument or defense advanced by Indemnitee in such action or arbitration was either
frivolous or not made in good faith. 
 (e)     Notwithstanding anything in this Agreement to the
contrary, no determination as to entitlement to indemnification shall be required to be made prior to the final disposition of the Proceeding. 

13.     Contribution. To the fullest extent permissible under applicable law, if the
indemnification provided for in this Agreement is unavailable to Indemnitee, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amounts incurred by Indemnitee, whether for Expenses, judgments, fines or amounts paid or to be
paid in settlement, in 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 events and transactions giving rise to such Proceeding; and (ii) the relative fault of Indemnitee and the Company (and its other directors, officers, employees and
agents) in connection with such events and transactions. 
 14.     Non-exclusivity. The rights of indemnification and to receive advancement of Expenses 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 Company’s certificate of incorporation or bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. To the extent that a change in Delaware law, whether by statute or judicial
decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the Company’s certificate of incorporation and bylaws 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, subject to the restrictions expressly set forth herein or therein. Except as expressly set forth herein, 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. Except as expressly set forth herein, 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. 

  
 -10- 








 15.     Primary Responsibility. The Company
acknowledges that to the extent Indemnitee is serving as a director on the Company’s board of directors at the request or direction of a venture capital fund or other entity and/or certain of its affiliates (collectively, the
“Secondary Indemnitors”), Indemnitee may have certain rights to indemnification and advancement of expenses provided by such Secondary Indemnitors. The Company agrees that, as between the Company and the Secondary
Indemnitors, the Company is primarily responsible for amounts required to be indemnified or advanced under the Company’s certificate of incorporation or bylaws or this Agreement and any obligation of the Secondary Indemnitors to provide
indemnification or advancement for the same amounts is secondary to those Company obligations. To the extent not in contravention of any insurance policy or policies providing liability or other insurance for the Company or any director, trustee,
general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise, the Company waives any right of contribution or subrogation against the Secondary Indemnitors with respect to the liabilities for which
the Company is primarily responsible under this Section 15. In the event of any payment by the Secondary Indemnitors of amounts otherwise required to be indemnified or advanced by the Company under the Company’s certificate of
incorporation or bylaws or this Agreement, the Secondary Indemnitors shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee for indemnification or advancement of expenses under the Company’s certificate
of incorporation or bylaws or this Agreement or, to the extent such subrogation is unavailable and contribution is found to be the applicable remedy, shall have a right of contribution with respect to the amounts paid. The Secondary Indemnitors are
express third-party beneficiaries of the terms of this Section 15. 

16.     No Duplication of Payments. The Company shall not be liable under this Agreement to make
any payment of amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received payment for such amounts under any insurance policy, contract, agreement
or otherwise. 
 17.     Insurance. To the extent that the Company maintains an insurance policy
or policies providing liability insurance for directors, trustees, general partners, managing members, officers, employees, agents or fiduciaries of the Company or any other Enterprise, Indemnitee shall be covered by such policy or policies to the
same extent as the most favorably-insured persons under such policy or policies in a comparable position. 

18.     Subrogation. 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, who shall execute 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. 
 19.     Services to the Company. Indemnitee
agrees to serve as a director or officer of the Company or, at the request of the Company, as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of another Enterprise, for so long as Indemnitee is duly
elected or appointed or until Indemnitee tenders his or her resignation or is removed from such position. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed
by operation of law), in which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its


  
 -11- 








 
subsidiaries or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that any employment with the Company (or any of its subsidiaries or any Enterprise) is at will, and Indemnitee
may be discharged at any time for any reason, with or without cause, with or without notice, except as may be otherwise expressly provided in any executed, written employment contract or change of control agreement between Indemnitee and the Company
(or any of its subsidiaries or any Enterprise), any existing formal severance policies adopted by the Company’s board of directors or, with respect to service as a director or officer of the Company, the Company’s certificate of
incorporation or bylaws or the DGCL. No such document shall be subject to any oral modification thereof. In the event that any indemnification provision in any written employment contract or change of control agreement conflicts with this Agreement,
the provisions of this Agreement will govern. 
 20.     Duration. This Agreement shall continue
until and terminate upon the later of (a) ten years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or as a director, trustee, general partner, managing member, officer, employee, agent or
fiduciary of any other Enterprise, as applicable; or (b) one year after the final termination of any Proceeding, including any appeal, then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses
hereunder and of any proceeding commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto. 

21.     Successors. This Agreement shall be binding upon the Company and its successors and
assigns, 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, and shall inure to the benefit of Indemnitee and Indemnitee’s heirs,
executors and administrators. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company, by written agreement,
expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

22.     Severability. Nothing in this Agreement is intended to require or shall be construed as
requiring the Company to do or fail to do any act in violation of applicable law. The Company’s inability, pursuant to court order or other applicable law, to perform its obligations under this Agreement shall not constitute a breach of this
Agreement. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Agreement (including
without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby
and shall remain enforceable to the fullest extent permitted by law; (ii) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties
hereto; and (iii) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is
not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby.

 23.     Enforcement. The Company expressly confirms
and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this
Agreement in serving as a director or officer of the Company. 
 24.     Entire Agreement. 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; provided, however, that this Agreement is a supplement to and in furtherance of the Company’s certificate of incorporation and bylaws and applicable law. 

25.     Modification and Waiver. No supplement, modification or amendment to this Agreement shall
be binding unless executed in writing by the parties hereto. No amendment, alteration or repeal of this Agreement shall adversely affect any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his
or her Corporate Status prior to such amendment, alteration or repeal. No waiver of any of the provisions of this Agreement shall constitute or be deemed a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing
waiver. 
 26.     Notices. All notices and other communications required or permitted hereunder
shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by electronic mail or otherwise delivered by hand, messenger or courier service addressed: 

(a)     if to Indemnitee, to Indemnitee’s address or electronic mail address as shown on the
signature page of this Agreement or in the Company’s records, as may be updated in accordance with the provisions hereof; or

Goodrich & Rosati, P.C., 12235 El Camino Real, Suite 200, San Diego, California 92130. 
 Each such notice or other

freight prepaid, specifying next-business-day delivery, one business day after deposit with the courier), or (ii) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained
receptacle for the deposit of the United States mail, addressed and mailed as aforesaid. 
 27.    
Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of
laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 12(a) of this Agreement, or except as mutually agreed by the parties in writing, the Company and Indemnitee hereby irrevocably and unconditionally
(i) agree that any action or proceeding arising out of or in connection with this

to submit to the exclusive jurisdiction of the Delaware Court of Chancery for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) appoint, to the extent such party is not otherwise subject to service
of process in the State of Delaware, The Corporation Trust Company, Wilmington, Delaware as its agent in the State of Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding against such

28.     Counterparts. This Agreement may be executed in one or more counterparts, each of which
shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. This Agreement may also be executed and delivered by facsimile signature and in counterparts, each of which shall for all
purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this
Agreement. 
 29. Captions. The headings of the paragraphs of this Agreement are inserted for convenience only and
