 Exhibit 10.1 

NKARTA, INC. 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is effective as of [________], 2020 and is between Nkarta, Inc., a
Delaware corporation (the “Company”), and [______________] (“Indemnitee”). 
 RECITALS

 A. Indemnitee’s service to the Company substantially benefits 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 to
contractually obligate itself to indemnify, and to advance expenses on behalf of, Indemnitee as permitted by applicable law. 
 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

(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; provided that, notwithstanding the foregoing,
a Change in Control shall not be deemed to occur if any such change in Beneficial Ownership of the Company’s securities by any Person results solely from (A) a reduction in the aggregate number of outstanding shares of securities entitled
to vote generally in the election of directors, or (B) a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities that is approved by at least a

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;

amended, whether or not the Company is then subject to such reporting requirement.

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. 

  
 -3- 

 (h) “Proceeding” means any threatened, pending or completed formal
or informal action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in
the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative, regulatory or investigative nature, including any appeal therefrom and including without limitation any such Proceeding pending as of the date of

taken by Indemnitee or any action or inaction on Indemnitee’s part while acting pursuant to Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which
indemnification or advancement of expenses can be provided under this Agreement. If the Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under
this paragraph. 
 (i) Reference to “other enterprises” shall include employee benefit plans; references to
“fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director,
officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith
and in a manner he or she reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the
Company” as referred to in this Agreement. 
 2. Indemnity in Third-Party Proceedings. The Company shall hold harmless
and indemnify Indemnitee to the fullest extent permitted by applicable law 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 by reason of Indemnitee’s Corporate Status. Pursuant to this Section 2, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all
Expenses, judgments, penalties, 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 and, with respect to any criminal Proceeding, had no reasonable cause to believe that his or her conduct was unlawful. 

3. Indemnity in Proceedings by or in the Right of the Company. The Company shall hold harmless and indemnify Indemnitee to the fullest
extent permitted by applicable law in accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its
favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on
Indemnitee’s 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. If
applicable law so provides, no indemnification for Expenses shall be made under this Section 3 in 

  
 -4- 

 
respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been finally 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 such court shall deem proper. 
 4. 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 a party to or a participant in and is successful (on the merits or otherwise) in defense of any Proceeding or any
claim, issue or matter therein, the Company shall hold harmless and indemnify Indemnitee to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in
connection therewith. To the fullest extent permitted by applicable law, if Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, in defense of 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 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. 
 5. Indemnification for Expenses of a Witness. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness, or is or was made (or asked) to respond to discovery requests or otherwise participate, in any Proceeding to which
Indemnitee is not a party, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

6. Additional Indemnification. 

(a) If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses, but
not, however, for the total amount therefor, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. If the Company disputes a portion of the amounts for which indemnification is requested, the
undisputed portion shall be paid and only the disputed portion withheld pending resolution of any such dispute. 
 (b) Notwithstanding any
limitation in Sections 2, 3, 4 or 5, the Company shall hold harmless and 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) by reason of Indemnitee’s Corporate Status, including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of
Indemnitee, against all Expenses, judgments, penalties, 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. 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 this Agreement) to be unlawful. 

  
 -5- 

 (c) For purposes of this Agreement, 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. 
 (d) If (i) Indemnitee is or was affiliated
with one or more venture capital funds and/or one or more other entities that has invested in the Company (an “Appointing Stockholder”), and (ii) Appointing Stockholder is, or is threatened to be made, a party to or a
participant in any Proceeding relating to or arising by reason of Appointing Stockholder’s position as a stockholder of, or lender to, the Company, or Appointing Stockholder’s appointment of or affiliation with Indemnitee or any other
director, including, without limitation, any alleged misappropriation of a Company asset or corporate opportunity, any claim of misappropriation or infringement of intellectual property relating to the Company, any alleged false or misleading
statement or omission made by the Company (or on its behalf) or its employees or agents, or any allegation of inappropriate control or influence over the Company or the members of its board of directors, officers, equity holders or debt holders,
then Appointing Stockholder will be entitled to indemnification hereunder for Expenses to the same extent as Indemnitee, and the terms of this Agreement as they relate to procedures for indemnification of Indemnitee and advancement of Expenses shall
apply to any such indemnification of Appointing Stockholder. 
 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 claim made against Indemnitee: 
 (a) for
which payment has actually been made to or on behalf of Indemnitee under any statute, insurance policy, indemnity provision, vote or otherwise, except with respect to any excess beyond the amount paid or with respect to any amounts paid under any
insurance policy or other indemnity provision, provided, that the foregoing shall not affect the rights of Indemnitee or the Secondary Indemnitors (as defined below) in Section 15 hereof; 

(b) for an accounting or disgorgement 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 federal, state or local statutory law or common law; 

  
 -6- 

 (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), or any reimbursement of the Company by Indemnitee of any compensation pursuant to any compensation recoupment or clawback policy adopted by the Company’s board of directors
or the compensation committee of the Company’s board of directors, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act; 

(d) in connection with 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) such indemnity arises in connection with any
mandatory counterclaim or cross claim brought or raised by Indemnitee in any Proceeding (or the relevant part of the Proceeding), (iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company
under applicable law, (iv) otherwise authorized in Section 12(d) or (v) otherwise required by applicable law; or 
 (e) if
prohibited by applicable law. 
 8. Advances of Expenses. Notwithstanding any other provision of this Agreement, the Company shall
advance the Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding, 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, whether prior to or after final disposition of such Proceeding (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. 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. This Section 8 shall not apply to any Proceeding for which indemnity is excluded pursuant to Sections 7(b) or 7(c). 

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, and any delay in so notifying the Company
shall not constitute a waiver by Indemnitee of any rights, except to the extent that such failure or delay actually and materially prejudices the interests of the Company. 

  
 -7- 

 (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 necessary or desirable 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) In the event the Company may be obligated to make any indemnity in connection with a Proceeding, the Company shall be entitled to assume
the defense of such Proceeding with counsel approved by Indemnitee, which approval shall not be unreasonably withheld, upon the delivery to Indemnitee of written notice of its election to do so. After delivery of such notice, approval of such
counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee for any fees or expenses of counsel subsequently incurred by Indemnitee with respect to the same Proceeding. Notwithstanding the
Company’s assumption of the defense of any such Proceeding, the Company shall be obligated to pay the fees and expenses of Indemnitee’s counsel to the extent (i) the employment of counsel by Indemnitee is authorized by the Company,
(ii) counsel for the Company or Indemnitee shall have reasonably concluded that there is a conflict of interest between the Company and Indemnitee in the conduct of any such defense such that Indemnitee needs to be separately represented,
(iii) the fees and expenses are non-duplicative and reasonably incurred in connection with Indemnitee’s role in the Proceeding despite the Company’s assumption of the defense, (iv) the
Company is not financially or legally able to perform its indemnification obligations or (v) the Company shall not have retained, or shall not continue to retain, such counsel to defend such Proceeding. The Company shall have the right to
conduct such defense as it sees fit in its sole discretion. Regardless of any provision in this Agreement, Indemnitee shall have the right to employ counsel in any Proceeding at Indemnitee’s personal expense. The Company shall not be entitled,
without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the Company. 
 (d) Indemnitee shall
give the Company such information and cooperation in connection with the Proceeding as may be reasonably appropriate. 
 (e) The Company
shall not be liable to indemnify Indemnitee for any settlement of any Proceeding (or any part thereof) without the Company’s prior written consent, which shall not be unreasonably withheld. 

(f) The Company shall not settle any Proceeding (or any part thereof) without Indemnitee’s prior written consent, which shall not be
unreasonably withheld, unless such settlement includes a complete and unconditional release of Indemnitee from all liability on all claims that are the subject matter of such Proceeding.

 10. Procedures upon Application for 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, 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. The Company shall, as soon as
reasonably practicable after receipt of such a request for indemnification, advise the board of directors that Indemnitee has requested indemnification. Any delay in providing the request will not relieve the Company from its obligations under this
Agreement, except to the extent such failure actually and materially prejudices the interests of the Company. 
 (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 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), to the
extent permitted by applicable law, and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled
to indemnification, including a description of any reason or basis for which indemnification has been denied. 
 (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 (unless Indemnitee shall request that such selection be made by the Company’s board 

  
 -9- 

 
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). 
 (d) The Company agrees to pay the reasonable fees and expenses of any Independent Counsel 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. The Company agrees to pay any and all reasonable fees and expenses incident to the procedures of
Section 10(c), regardless of the manner in which such Independent Counsel was selected or appointed. 
 (e) If the person, persons or
entity empowered or selected under Sections 10 or 11 of this Agreement 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 sixty (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 10(e) shall not apply if the
determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 10(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for
such determination, the Company’s board of directors or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their 

  
 -10- 

 
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. 

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 if Indemnitee has submitted a request for indemnification in accordance with Section 10(a) of this
Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by such person, persons or entity of any determination contrary to 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 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 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) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith to the extent Indemnitee
relied in good faith on (i) the records or books of account of the Enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, (iii) the advice
of legal counsel for the Enterprise or its board of directors or counsel selected by any committee of the board of directors or (iv) information or records given or reports made to the Enterprise by an independent certified public accountant,
an appraiser, investment banker or other expert selected with reasonable care by the Enterprise or its board of directors or any committee of the board of directors. The provisions of this Section 11(c) shall not be deemed to be exclusive or to
limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement, and 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. 

(d) Neither the knowledge, actions nor failure to act of any other director, officer, trustee, partner, managing member, fiduciary, agent or
employee of the Enterprise shall be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

  
 -11- 

 (e) 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. 
 12. Remedies of
Indemnitee. 
 (a) Subject to Section 12(d), 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 60 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, 6(a) 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 be a defense to the action or 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. 

  
 -12- 

 (c) If a determination shall have been made pursuant to Section 10 of this Agreement
that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any 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 statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) To the 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, and, if requested by Indemnitee,
shall (as soon as reasonably practicable, but in any event no later than 10 days, after receipt by the Company of a written request therefor) advance such Expenses to Indemnitee, subject to the provisions of Section 8. 

(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. 
 (f) 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. 
 13. Contribution. 

(a) To the fullest extent permitted by applicable law, 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 actually and reasonably incurred by Indemnitee, whether for Expenses, judgments, penalties, 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 cause to such Proceeding and (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with
such events and transactions. 
 (b) The Company hereby agrees to indemnify and hold harmless Indemnitee from any claims for contribution
which may be brought by directors, officers or employees of the Company (other than Indemnitee) who may be jointly liable with Indemnitee. 

(c) Whether or not the indemnification provided for in this Agreement is available, in respect of any Proceeding in which the Company is
jointly liable with Indemnitee, the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such 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 Proceeding in which the Company is jointly liable with Indemnitee unless such settlement provides for a full and final
release of all claims asserted against Indemnitee. 

  
 -13- 

 (d) 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, 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, on the one hand, and Indemnitee, on the other hand, from the transaction or events 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, on the one hand, and Indemnitee, on the other hand, in connection with the transaction or 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, 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. 
 (e) Notwithstanding anything to the contrary, no person or entity
found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act of 1933, as amended) shall be entitled to contribution from any person or entity who was not found guilty of such fraudulent
misrepresentation. 
 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. 

  
 -14- 

 15. [Primary Responsibility. The Company hereby acknowledges that Indemnitee has
certain rights to indemnification, advancement of expenses and/or insurance provided by [[________________________] and certain of its affiliates]1 (collectively, the “Secondary
Indemnitors”). 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 Secondary 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 Secondary Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Secondary Indemnitors from any and all claims against the Secondary
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 Secondary 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 Secondary 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 Secondary Indemnitors are express third party beneficiaries of the terms of this Section 15.] 

16. No Duplication of Payments. Except as provided in Section 15 above, 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, 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 coverage
available for any such director, trustee, general partner, managing member, officer, agent or fiduciary under such policy or policies. 

18. Subrogation. Except as provided in Section 15 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 Secondary Indemnitors), 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, dies 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 

 

	1 	 [NTD: To be updated, as applicable, for relevant Indemnitees.]

  
 -15- 

 
Company (or any of its 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 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. 
 20. Duration of Agreement. This
Agreement shall continue for the duration of Indemnitee’s service as a director of the Company or as a director, trustee, partner, management member, officer, employee, agent, fiduciary, stockholder or controlling person of the Company or any
other Enterprise and thereafter for so long as Indemnitee may be subject to any pending or possible claim due to Indemnitee’s Corporate Status (or any claim arising from a Proceeding commenced under Section 12 hereof), 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. 

21. Successors. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of
Indemnitee and, as the case may be, Indemnitee’s spouse, heirs, executors, administrators, successors and assigns. 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 and/or assets of the Company, 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. Additionally, (if requested by any Indemnitee in the event of any change in control as defined in the Company’s then current directors’ and officers’ liability insurance and fiduciary liability insurance policies ), the Company
shall pay up to an amount equal to 250% of the premium of such directors’ and officers’ liability insurance and fiduciary liability insurance policies to purchase or cause to be purchased a six-year
extended reporting period (“Tail Coverage”) under those policies or comparable (in quality of coverage and quality of insurer) replacement policies. In the event the Company cannot purchase Tail Coverage with respect to the entirety
of the then current directors’ and officers’ liability and fiduciary liability insurance policies for such premium amount, the Company shall purchase the amount of Tail Coverage as the Company is able to purchase for such premium amount.

 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 applicable 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 

  
 -16- 

 
the intent of the parties hereto; and (iii) to the fullest extent permitted by applicable law, 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. Without limiting the
generality of the foregoing, this Agreement is intended to confer upon Indemnitee and Appointing Stockholder indemnification rights to the fullest extent permitted by applicable law. 

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. The Company shall not seek
from a court, or agree to, a “bar order” which would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement. 

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, termination 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 facsimile or electronic mail or otherwise delivered by hand, messenger or courier service addressed:

 (a) if to Indemnitee, to Indemnitee’s address, facsimile number 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, with a copy (which shall not constitute notice) to [______________________________________]; or 

(b) if to the Company, to the attention of the Chief Executive Officer or Chief Financial Officer of the Company at such address as the
Company shall have furnished to Indemnitee, with a copy (which shall not constitute notice) to C. Brophy Christensen, O’Melveny & Myers LLP., Two Embarcadero Center, 28th Floor, San
Francisco, CA 94111. 

  
 -17- 

 Each such notice or other communication shall for all purposes of this Agreement be treated
as effective or having been given (i) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying
next-business-day delivery, one business day after deposit with the courier), (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, or (iii) if sent via facsimile, upon confirmation of facsimile transfer or, if sent via electronic mail, upon confirmation of delivery when directed to the
relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day. 

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, the Company
and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court of Chancery, and not in any other state or federal
court in the United States of America or any court in any other country, (ii) consent 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 party with the same legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying
of venue of any such action or proceeding in the Delaware Court of Chancery, and (v) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court of Chancery has been brought in an
improper or inconvenient forum. 
 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 shall not be deemed to
constitute part of this Agreement or to affect the construction thereof.

 Exhibit 10.4 

NKARTA, INC. 
 2020
PERFORMANCE INCENTIVE PLAN 
  

	1.	 PURPOSE OF PLAN 

The purpose of this Nkarta, Inc. 2020 Performance Incentive Plan (this “Plan”) of Nkarta, Inc., a Delaware corporation (the
“Corporation”), is to promote the success of the Corporation by providing an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons and to enhance the
alignment of the interests of the selected participants with the interests of the Corporation’s stockholders. 
  

	2.	 ELIGIBILITY 

The Administrator (as such term is defined in Section 3.1) may grant awards under this Plan only to those persons that the Administrator
determines to be Eligible Persons. An “Eligible Person” is any person who is either: (a) an officer (whether or not a director) or employee of the Corporation or one of its Subsidiaries; (b) a director of the Corporation
or one of its Subsidiaries; or (c) an individual consultant or advisor who renders or has rendered bona fide services (other than services in connection with the offering or sale of securities of the Corporation or one of its Subsidiaries in a
capital-raising transaction or as a market maker or promoter of securities of the Corporation or one of its Subsidiaries) to the Corporation or one of its Subsidiaries and who is selected to participate in this Plan by the Administrator; provided,
however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either the Corporation’s eligibility to use Form S-8 to register under the Securities Act of 1933, as amended (the “Securities Act”), the offering and sale of shares issuable under this Plan by the Corporation or the Corporation’s compliance
with any other applicable laws. An Eligible Person who has been granted an award (a “participant”) may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As used herein,
“Subsidiary” means any corporation or other entity a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by the Corporation; and “Board” means the Board of
Directors of the Corporation. 
  

	3.	 PLAN ADMINISTRATION 

 

	 	3.1	 The Administrator. This Plan shall be administered by and all awards under this Plan shall
be authorized by the Administrator. The “Administrator” means the Board or one or more committees (or subcommittees, as the case may be) appointed by the Board or another committee (within its delegated authority) to administer all
or certain aspects of this Plan. Any such committee shall be comprised solely of one or more directors or such number of directors as may be required under applicable law. A committee may delegate some or all of its authority to another committee so
constituted. The Board or a committee comprised solely of directors may also delegate, to the extent permitted by applicable law, to one or more officers of the Corporation, its authority under this Plan. The Board or another committee (within its
delegated authority) may delegate different levels of authority to different committees or persons with 

  
 1 

	 	
administrative and grant authority under this Plan. Unless otherwise provided in the Bylaws of the Corporation or the applicable charter of any Administrator: (a) a majority of the members
of the acting Administrator shall constitute a quorum, and (b) the vote of a majority of the members present assuming the presence of a quorum or the unanimous written consent of the members of the Administrator shall constitute action by the
acting Administrator. 

  

	 	3.2	 Powers of the Administrator. Subject to the express provisions of this Plan, the
Administrator is authorized and empowered to do all things necessary or desirable in connection with the authorization of awards and the administration of this Plan (in the case of a committee or delegation to one or more officers, within any
express limits on the authority delegated to that committee or person(s)), including, without limitation, the authority to: 

  

	 	(a)	 determine eligibility and, from among those persons determined to be eligible, determine the particular
Eligible Persons who will receive an award under this Plan; 

  

	 	(b)	 grant awards to Eligible Persons, determine the price (if any) at which securities will be offered or awarded
and the number of securities to be offered or awarded to any of such persons (in the case of securities-based awards), determine the other specific terms and conditions of awards consistent with the express limits of this Plan, establish the
installment(s) (if any) in which such awards shall become exercisable or shall vest (which may include, without limitation, performance and/or time-based schedules), or determine that no delayed exercisability or vesting is required, establish any
applicable performance-based exercisability or vesting requirements, determine the circumstances in which any performance-based goals (or the applicable measure of performance) will be adjusted and the nature and impact of any such adjustment,
determine the extent (if any) to which any applicable exercise and vesting requirements have been satisfied, establish the events (if any) on which exercisability or vesting may accelerate (which may include, without limitation, retirement and other
specified terminations of employment or services, or other circumstances), and establish the events (if any) of termination, expiration or reversion of such awards; 

 

	 	(c)	 approve the forms of any award agreements (which need not be identical either as to type of award or among
participants); 

  

	 	(d)	 construe and interpret this Plan and any agreements defining the rights and obligations of the Corporation, its
Subsidiaries, and participants under this Plan, make any and all determinations under this Plan and any such agreements, further define the terms used in this Plan, and prescribe, amend and rescind rules and regulations relating to the
administration of this Plan or the awards granted under this Plan; 

  
 2 

	 	(e)	 cancel, modify, or waive the Corporation’s rights with respect to, or modify, discontinue, suspend, or
terminate any or all outstanding awards, subject to any required consent under Section 8.6.5; 

  

	 	(f)	 accelerate, waive or extend the vesting or exercisability, or modify or extend the term of, any or all such
outstanding awards (in the case of options or stock appreciation rights, within the maximum term of such awards) in such circumstances as the Administrator may deem appropriate (including, without limitation, in connection with a retirement or other
termination of employment or services, or other circumstances) subject to any required consent under Section 8.6.5; 

  

	 	(g)	 adjust the number of shares of Common Stock subject to any award, adjust the price of any or all outstanding
awards or otherwise waive or change previously imposed terms and conditions, in such circumstances as the Administrator may deem appropriate, in each case subject to Sections 4 and 8.6 (and subject to the no repricing provision below);

  

	 	(h)	 determine the date of grant of an award, which may be a designated date after but not before the date of the
Administrator’s action to approve the award (unless otherwise designated by the Administrator, the date of grant of an award shall be the date upon which the Administrator took the action approving the award); 

 

	 	(i)	 determine whether, and the extent to which, adjustments are required pursuant to Section 7.1 hereof and
take any other actions contemplated by Section 7 in connection with the occurrence of an event of the type described in Section 7; 

  

	 	(j)	 acquire or settle (subject to Sections 7 and 8.6) rights under awards in cash, stock of equivalent value, or
other consideration (subject to the no repricing provision below); and 

  

	 	(k)	 determine the fair market value of the Common Stock or awards under this Plan from time to time and/or the
manner in which such value will be determined. 

  

	 	3.3	 Prohibition on Repricing. Notwithstanding anything to the contrary in Section 3.2 and
except for an adjustment pursuant to Section 7.1 or a repricing approved by stockholders, in no case may the Administrator (1) amend an outstanding stock option or SAR to reduce the exercise price or base price of the award,
(2) cancel, exchange, or surrender an outstanding stock option or SAR in exchange for cash or other awards for the purpose of repricing the award, or (3) cancel, exchange, or surrender an outstanding stock option or SAR in exchange for an
option or SAR with an exercise or base price that is less than the exercise or base price of the original award.

	 	3.4	 Binding Determinations. Any determination or other action taken by, or inaction of, the
Corporation, any Subsidiary, or the Administrator relating or pursuant to this Plan (or any award made under this Plan) and within its authority hereunder or under applicable law shall be within the absolute discretion of that entity or body and
shall be conclusive and binding upon all persons. Neither the Board nor any other Administrator, nor any member thereof or person acting at the direction thereof, shall be liable for any act, omission, interpretation, construction or determination
made in good faith in connection with this Plan (or any award made under this Plan), and all such persons shall be entitled to indemnification and reimbursement by the Corporation in respect of any claim, loss, damage or expense (including, without
limitation, attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors and officers liability insurance coverage that may be in effect from time to time. Neither the Board nor any other
Administrator, nor any member thereof or person acting at the direction thereof, nor the Corporation or any of its Subsidiaries, shall be liable for any damages of a participant should an option intended as an ISO (as defined below) fail to meet the
requirements of the Internal Revenue Code of 1986, as amended (the “Code”), applicable to ISOs, should any other award(s) fail to qualify for any intended tax treatment, should any award grant or other action with respect thereto
not satisfy Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, or otherwise for any tax or other liability imposed on a participant with respect to an award. 

 

	 	3.5	 Reliance on Experts. In making any determination or in taking or not taking any action
under this Plan, the Administrator may obtain and may rely upon the advice of experts, including employees and professional advisors to the Corporation. No director, officer or agent of the Corporation or any of its Subsidiaries shall be liable for
any such action or determination taken or made or omitted in good faith. 

  

	 	3.6	 Delegation. The Administrator may delegate ministerial,
non-discretionary functions to individuals who are officers or employees of the Corporation or any of its Subsidiaries or to third parties. 

 

	4.	 SHARES OF COMMON STOCK SUBJECT TO THE PLAN; SHARE LIMITS 

 

	 	4.1	 Shares Available. Subject to the provisions of Section 7.1, the capital stock that
may be delivered under this Plan shall be shares of the Corporation’s authorized but unissued Common Stock and any shares of its Common Stock held as treasury shares. For purposes of this Plan, “Common Stock” shall mean the
common stock of the Corporation and such other securities or property as may become the subject of awards under this Plan, or may become subject to such awards, pursuant to an adjustment made under Section 7.1. 

 

	 	4.2	 Aggregate Share Limit. The maximum number of shares of Common Stock that may be delivered
pursuant to awards granted to Eligible Persons under this Plan (the “Share Limit”) is equal to the sum of the following: 

  

	 	(1)	 2,660,371 shares of Common Stock, plus 

  
 4 

	 	(2)	 the number of any shares subject to stock options granted under the Corporation’s 2015 Equity Incentive
Plan (the “2015 Plan”) and outstanding on the date of stockholder approval of this Plan (the “Stockholder Approval Date”) which expire, or for any reason are cancelled or terminated, after the Stockholder Approval
Date without being exercised, plus 

  

	 	(3)	 the number of any shares subject to restricted stock awards granted under the 2015 Plan that are outstanding
and unvested on the Stockholder Approval Date that are forfeited, terminated, cancelled or otherwise reacquired by the Corporation without having become vested. 

In addition, the Share Limit shall automatically increase on the first trading day in January of each calendar year during the term of this
Plan, commencing with January 2021, by an amount equal to the lesser of (i) five percent (5%) of the total number of shares of Common Stock issued and outstanding on December 31 of the immediately preceding calendar year or (ii) such
number of shares of Common Stock as may be established by the Board. 
  

	 	4.3	 Additional Share Limits. The following limits also apply with respect to awards granted
under this Plan. These limits are in addition to, not in lieu of, the aggregate Share Limit in Section 4.2. 

  

	 	(a)	 The maximum number of shares of Common Stock that may be delivered pursuant to options qualified as incentive
stock options granted under this Plan is 2,660,371 shares. 

  

	 	(b)	 Awards that are granted under this Plan during any one calendar year to any person who, on the grant date of
the award, is a non-employee director are subject to the limits of this Section 4.3(b). The maximum number of shares of Common Stock subject to those awards that are granted under this Plan during any one
calendar year to an individual who, on the grant date of the award, is a non-employee director is the number of shares that produce a grant date fair value for the award that, when combined with (i) the
grant date fair value of any other awards granted under this Plan during that same calendar year to that individual in his or her capacity as a non-employee director and (ii) the dollar amount of all
other cash compensation payable by the Corporation to such non-employee director for his or her services in such capacity during that same calendar year (regardless of whether deferred and excluding any
interest or earnings on any portion of such amount that may be deferred), is $750,000; provided that this limit is $1,000,000 as to (1) a non-employee director who is serving as the independent Chair of
the Board or as a lead independent director at the time the applicable grant is made or (2) any new non-employee director for the calendar year in which the
non-employee director is first elected or appointed to the Board. For purposes of this Section 4.3(b), a “non-employee director” is an individual who, on
the grant date of the award, is a member of the Board who is not then an officer or employee of the Corporation or one of its Subsidiaries. For purposes of this Section 4.3(b), “grant date fair value” means the value of the award as
of the date of grant of the award and as determined using the 

  
 5 

	 	
equity award valuation principles applied in the Corporation’s financial reporting. The limits of this Section 4.3(b) do not apply to, and shall be determined without taking into
account, any award granted to an individual who, on the grant date of the award, is an officer or employee of the Corporation or one of its Subsidiaries. The limits of this Section 4.3(b) apply on an individual basis and not on an aggregate
basis to all non-employee directors as a group. 

  

	 	4.4	 Share-Limit Counting Rules. The Share Limit shall be subject to the following provisions
of this Section 4.4: 

  

	 	(a)	 Shares that are subject to or underlie awards granted under this Plan which expire or for any reason are
cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under this Plan shall not be counted against the Share Limit and shall be available for subsequent awards under this Plan. 

 

	 	(b)	 Except as provided below, to the extent that shares of Common Stock are delivered pursuant to the exercise of a
stock appreciation right granted under this Plan, the number of underlying shares which are actually issued in payment of the award shall be counted against the Share Limit. (For purposes of clarity, if a stock appreciation right relates to 100,000
shares and is exercised in full at a time when the payment due to the participant is 15,000 shares, 15,000 shares shall be counted against the Share Limit with respect to such exercise and the 85,000 shares not issued shall not be counted against
the Share Limit and shall be available for subsequent awards under this Plan.) 

  

	 	(c)	 Shares that are exchanged by a participant or withheld by the Corporation as full or partial payment in
connection with any award granted under this Plan, as well as any shares exchanged by a participant or withheld by the Corporation or one of its Subsidiaries to satisfy the tax withholding obligations related to any award granted under this Plan,
shall not be counted against the Share Limit and shall be available for subsequent awards under this Plan. 

  

	 	(d)	 To the extent that an award granted under this Plan is settled in cash or a form other than shares of Common
Stock, the shares that would have been delivered had there been no such cash or other settlement shall not be counted against the Share Limit and shall be available for subsequent awards under this Plan. 

 

	 	(e)	 In the event that shares of Common Stock are delivered in respect of a dividend equivalent right granted under
this Plan, the number of shares delivered with respect to the award shall be counted against the Share Limit. (For purposes of clarity, if 1,000 dividend equivalent rights are granted and outstanding when the Corporation pays a dividend, and 50
shares are delivered in payment of those rights with respect to that dividend, 50 shares shall be counted against the Share Limit). Except as otherwise provided by the Administrator, shares delivered in respect of dividend equivalent rights shall
not count against any individual award limit under this Plan other than the aggregate Share Limit. 

  
 6 

	 	(f)	 The Corporation may not increase the Share Limit by repurchasing shares of Common Stock on the market (by using
cash received through the exercise of stock options or otherwise). 

 Refer to Section 8.10 for application of the
share limits of this Plan, including the limits in Sections 4.2 and 4.3, with respect to assumed awards. Each of the numerical limits and references in Sections 4.2 and 4.3, and in this Section 4.4, is subject to adjustment as contemplated by
Sections 7 and 8.10. 
  

	 	4.5	 No Fractional Shares; Minimum Issue. Unless otherwise expressly provided by
the Administrator, no fractional shares shall be delivered under this Plan. The Administrator may pay cash in lieu of any fractional shares in settlements of awards under this Plan. The Administrator may from time to time impose a limit (of not
greater than 100 shares) on the minimum number of shares that may be purchased or exercised as to awards (or any particular award) granted under this Plan unless (as to any particular award) the total number purchased or exercised is the total
number at the time available for purchase or exercise under the award. 

  

	5.	 AWARDS 

  

	 	5.1	 Type and Form of Awards. The Administrator shall determine the type or types of award(s)
to be made to each selected Eligible Person. Awards may be granted singly, in combination or in tandem. Awards also may be made in combination or in tandem with, in replacement of, as alternatives to, or as the payment form for grants or rights
under any other employee or compensation plan of the Corporation or one of its Subsidiaries. The types of awards that may be granted under this Plan are: 

5.1.1 Stock Options. A stock option is the grant of a right to purchase a specified number of shares of Common Stock
during a specified period as determined by the Administrator. An option may be intended as an incentive stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified stock option (an option not
intended to be an ISO). The agreement evidencing the grant of an option will indicate if the option is intended as an ISO; otherwise it will be deemed to be a nonqualified stock option. The maximum term of each option (ISO or nonqualified) shall be
ten (10) years. The per share exercise price for each option shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the option. When an option is exercised, the exercise price for the shares to
be purchased shall be paid in full in cash or such other method permitted by the Administrator consistent with Section 5.4. 

  
 7 

 5.1.2 Additional Rules Applicable to ISOs. To the extent that the
aggregate fair market value (determined at the time of grant of the applicable option) of stock with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account both Common Stock subject
to ISOs under this Plan and stock subject to ISOs under all other plans of the Corporation or one of its Subsidiaries (or any parent or predecessor corporation to the extent required by and within the meaning of Section 422 of the Code and the
regulations promulgated thereunder), such options shall be treated as nonqualified stock options. In reducing the number of options treated as ISOs to meet the $100,000 limit, the most recently granted options shall be reduced first. To the extent a
reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Administrator may, in the manner and to the extent permitted by law, designate which shares of Common Stock are to be treated as shares acquired pursuant to the
exercise of an ISO. ISOs may only be granted to employees of the Corporation or one of its subsidiaries (for this purpose, the term “subsidiary” is used as defined in Section 424(f) of the Code, which generally requires an unbroken
chain of ownership of at least 50% of the total combined voting power of all classes of stock of each subsidiary in the chain beginning with the Corporation and ending with the subsidiary in question). No ISO may be granted to any person who, at the
time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined voting power of all classes of stock of the Corporation, unless the
exercise price of such option is at least 110% of the fair market value of the stock subject to the option and such option by its terms is not exercisable after the expiration of five years from the date such option is granted. If an
otherwise-intended ISO fails to meet the applicable requirements of Section 422 of the Code, the option shall be a nonqualified stock option. 

5.1.3 Stock Appreciation Rights. A stock appreciation right or “SAR” is a right to receive a payment, in
cash and/or Common Stock, equal to the excess of the fair market value of a specified number of shares of Common Stock on the date the SAR is exercised over the “base price” of the award, which base price shall be set forth in the
applicable award agreement and shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the SAR. The maximum term of a SAR shall be ten (10) years. 

5.1.4 Other Awards; Dividend Equivalent Rights. The other types of awards that may be granted under this Plan include:
(a) stock bonuses, restricted stock, performance stock, stock units, restricted stock units, deferred shares, phantom stock or similar rights to purchase or acquire shares, whether at a fixed or variable price (or no price) or fixed or variable
ratio related to the Common Stock, and any of which may (but need not) be fully vested at grant or vest upon the passage of time, the occurrence of one or more events, the satisfaction of performance criteria or other conditions, or any combination
thereof; or (b) cash awards. The types of cash awards that may be granted under this Plan include the opportunity to receive a payment for the achievement of one or more goals established by the Administrator, on such terms as the Administrator
may provide, as well as discretionary cash awards. Dividend equivalent rights may be granted as a separate award or in connection with another award under this Plan; provided, however, that dividend equivalent rights may not be granted as to a stock
option or SAR granted under this Plan. In addition, any dividends and/or dividend equivalents as to the portion of an award that is subject to unsatisfied vesting requirements will be subject to termination and forfeiture to the same extent as the
corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied. 

  
 8 

	 	5.2	 Award Agreements. Each award shall be evidenced by a written or electronic award agreement
or notice in a form approved by the Administrator (an “award agreement”), and, in each case and if required by the Administrator, executed or otherwise electronically accepted by the recipient of the award in such form and manner as the
Administrator may require. 

  

	 	5.3	 Deferrals and Settlements. Payment of awards may be in the form of cash, Common Stock,
other awards or combinations thereof as the Administrator shall determine, and with such restrictions (if any) as it may impose. The Administrator may also require or permit participants to elect to defer the issuance of shares or the settlement of
awards in cash under such rules and procedures as it may establish under this Plan. The Administrator may also provide that deferred settlements include the payment or crediting of interest or other earnings on the deferral amounts, or the payment
or crediting of dividend equivalents where the deferred amounts are denominated in shares. 

  

	 	5.4	 Consideration for Common Stock or Awards. The purchase price (if any) for any award
granted under this Plan or the Common Stock to be delivered pursuant to an award, as applicable, may be paid by means of any lawful consideration as determined by the Administrator, including, without limitation, one or a combination of the
following methods: 

  

	 	(a)	 services rendered by the recipient of such award; 

 

	 	(b)	 cash, check payable to the order of the Corporation, or electronic funds transfer; 

 

	 	(c)	 notice and third party payment in such manner as may be authorized by the Administrator; 

 

	 	(d)	 the delivery of previously owned shares of Common Stock; 

 

	 	(e)	 by a reduction in the number of shares otherwise deliverable pursuant to the award; or 

 

	 	(f)	 subject to such procedures as the Administrator may adopt, pursuant to a “cashless exercise” with a
third party who provides financing for the purposes of (or who otherwise facilitates) the purchase or exercise of awards. 

In no event shall any shares newly-issued by the Corporation be issued for less than the minimum lawful consideration for such shares or for
consideration other than consideration permitted by applicable state law. Shares of Common Stock used to satisfy the exercise price of an option shall be valued at their fair market value. The Corporation will not be obligated to deliver any shares
unless and until it receives full payment of the exercise or purchase price therefor and any 

  
 9 

 
related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement,
the Administrator may at any time eliminate or limit a participant’s ability to pay any purchase or exercise price of any award or shares by any method other than cash payment to the Corporation. 

 

	 	5.5	 Definition of Fair Market Value. For purposes of this Plan, “fair market value”
shall mean, unless otherwise determined or provided by the Administrator in the circumstances, the closing price (in regular trading) for a share of Common Stock on the Nasdaq Global Market (the “Market”) for the date in question
or, if no sales of Common Stock were reported on the Market on that date, the closing price (in regular trading) for a share of Common Stock on the Market for the next preceding day on which sales of Common Stock were reported on the Market. The
Administrator may, however, provide with respect to one or more awards that the fair market value shall equal the closing price (in regular trading) for a share of Common Stock on the Market on the last trading day preceding the date in question or
the average of the high and low trading prices of a share of Common Stock on the Market for the date in question or the most recent trading day. If the Common Stock is no longer listed or is no longer actively traded on the Market as of the
applicable date, the fair market value of the Common Stock shall be the value as reasonably determined by the Administrator for purposes of the award in the circumstances. The Administrator also may adopt a different methodology for determining fair
market value with respect to one or more awards if a different methodology is necessary or advisable to secure any intended favorable tax, legal or other treatment for the particular award(s) (for example, and without limitation, the Administrator
may provide that fair market value for purposes of one or more awards will be based on an average of closing prices (or the average of high and low daily trading prices) for a specified period preceding the relevant date). 

 

	 	5.6	 Transfer Restrictions. 

5.6.1 Limitations on Exercise and Transfer. Unless otherwise expressly provided in (or pursuant to) this Section 5.6
or required by applicable law: (a) all awards are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge;
(b) awards shall be exercised only by the participant; and (c) amounts payable or shares issuable pursuant to any award shall be delivered only to (or for the account of) the participant. 

5.6.2 Exceptions. The Administrator may permit awards to be exercised by and paid to, or otherwise transferred to, other
persons or entities pursuant to such conditions and procedures, including limitations on subsequent transfers, as the Administrator may, in its sole discretion, establish in writing. Any permitted transfer shall be subject to compliance with
applicable federal and state securities laws and shall not be for value (other than nominal consideration, settlement of marital property rights, or for interests in an entity in which more than 50% of the voting interests are held by the Eligible
Person or by the Eligible Person’s family members). 

  
 10 

 5.6.3 Further Exceptions to Limits on Transfer. The exercise and
transfer restrictions in Section 5.6.1 shall not apply to: 
  

	 	(a)	 transfers to the Corporation (for example, in connection with the expiration or termination of the award);

  

	 	(b)	 the designation of a beneficiary to receive benefits in the event of the participant’s death or, if the
participant has died, transfers to or exercise by the participant’s beneficiary, or, in the absence of a validly designated beneficiary, transfers by will or the laws of descent and distribution; 

 

	 	(c)	 subject to any applicable limitations on ISOs, transfers to a family member (or former family member) pursuant
to a domestic relations order if received by the Administrator; 

  

	 	(d)	 if the participant has suffered a disability, permitted transfers or exercises on behalf of the participant by
his or her legal representative; or 

  

	 	(e)	 the authorization by the Administrator of “cashless exercise” procedures with third parties who
provide financing for the purpose of (or who otherwise facilitate) the exercise of awards consistent with applicable laws and any limitations imposed by the Administrator. 

 

	 	5.7	 International Awards. One or more awards may be granted to Eligible Persons who provide
services to the Corporation or one of its Subsidiaries outside of the United States. Any awards granted to such persons may be granted pursuant to the terms and conditions of any applicable sub-plans, if any,
appended to this Plan and approved by the Administrator from time to time. The awards so granted need not comply with other specific terms of this Plan, provided that stockholder approval of any deviation from the specific terms of this Plan is not
required by applicable law or any applicable listing agency. 

  

	6.	 EFFECT OF TERMINATION OF EMPLOYMENT OR SERVICE ON AWARDS 

 

	 	6.1	 General. The Administrator shall establish the effect (if any) of a termination of
employment or service on the rights and benefits under each award under this Plan and in so doing may make distinctions based upon, inter alia, the cause of termination and type of award. If the participant is not an employee of the Corporation or
one of its Subsidiaries, is not a member of the Board, and provides other services to the Corporation or one of its Subsidiaries, the Administrator shall be the sole judge for purposes of this Plan (unless a contract or the award otherwise provides)
of whether the participant continues to render services to the Corporation or one of its Subsidiaries and the date, if any, upon which such services shall be deemed to have terminated. 

 

	 	6.2	 Events Not Deemed Terminations of Employment. Unless the express policy of the Corporation
or one of its Subsidiaries, or the Administrator, otherwise provides, or except as otherwise required by applicable law, the employment relationship shall not be considered terminated in the case of: (a) sick leave, (b) military leave, or
(c) any other leave of absence authorized by the Corporation or 

  
 11 

	 	
one of its Subsidiaries, or the Administrator; provided that, unless reemployment upon the expiration of such leave is guaranteed by contract or law or the Administrator otherwise provides, such
leave is for a period of not more than three months. In the case of any employee of the Corporation or one of its Subsidiaries on an approved leave of absence, continued vesting of the award while on leave from the employ of the Corporation or one
of its Subsidiaries may be suspended until the employee returns to service, unless the Administrator otherwise provides or applicable law otherwise requires. In no event shall an award be exercised after the expiration of any applicable maximum term
of the award. 

  

	 	6.3	 Effect of Change of Subsidiary Status. For purposes of this Plan and any award, if an
entity ceases to be a Subsidiary of the Corporation a termination of employment or service shall be deemed to have occurred with respect to each Eligible Person in respect of such Subsidiary who does not continue as an Eligible Person in respect of
the Corporation or another Subsidiary that continues as such after giving effect to the transaction or other event giving rise to the change in status unless the Subsidiary that is sold, spun-off or otherwise
divested (or its successor or a direct or indirect parent of such Subsidiary or successor) assumes the Eligible Person’s award(s) in connection with such transaction. 

 

	7.	 ADJUSTMENTS; ACCELERATION 

 

	 	7.1	 Adjustments. 

 

	 	(a)	 Subject to Section 7.2, upon (or, as may be necessary to effect the adjustment, immediately prior to): any
reclassification, recapitalization, stock split (including a stock split in the form of a stock dividend) or reverse stock split; any merger, combination, consolidation, conversion or other reorganization; any
spin-off, split-up, or similar extraordinary dividend distribution in respect of the Common Stock; or any exchange of Common Stock or other securities of the
Corporation, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; then the Administrator shall equitably and proportionately adjust: (1) the number and type of shares of Common Stock (or other
securities) that thereafter may be made the subject of awards (including the specific share limits, maximums and numbers of shares set forth elsewhere in this Plan); (2) the number, amount and type of shares of Common Stock (or other securities or
property) subject to any outstanding awards; (3) the grant, purchase, or exercise price (which term includes the base price of any SAR or similar right) of any outstanding awards; and/or (4) the securities, cash or other property
deliverable upon exercise or payment of any outstanding awards, in each case to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding awards. 

 

	 	(b)	 Without limiting the generality of Section 3.4, any good faith determination by the Administrator as to
whether an adjustment is required in the circumstances pursuant to this Section 7.1, and the extent and nature of any such adjustment, shall be conclusive and binding on all persons. 

  
 12 

	 	7.2	 Corporate Transactions—Assumption and Termination of Awards. 

 

	 	(a)	 Upon any event in which the Corporation does not survive, or does not survive as a public company in respect of
its Common Stock (including, without limitation, a dissolution, merger, combination, consolidation, conversion, exchange of securities, or other reorganization, or a sale of all or substantially all of the business, stock or assets of the
Corporation, in any case in connection with which the Corporation does not survive or does not survive as a public company in respect of its Common Stock), then the Administrator may make provision for a cash payment in settlement of, or for the
termination, assumption, substitution or exchange of any or all outstanding awards or the cash, securities or property deliverable to the holder of any or all outstanding awards, based upon, to the extent relevant under the circumstances, the
distribution or consideration payable to holders of the Common Stock upon or in respect of such event. Upon the occurrence of any event described in the preceding sentence in connection with which the Administrator has made provision for the award
to be terminated (and the Administrator has not made a provision for the substitution, assumption, exchange or other continuation or settlement of the award): (1) unless otherwise provided in the applicable award agreement, each then-outstanding
option and SAR shall become fully vested, all shares of restricted stock then outstanding shall fully vest free of restrictions, and each other award granted under this Plan that is then outstanding shall become payable to the holder of such award
(with any performance goals applicable to the award in each case being deemed met, unless otherwise provided in the award agreement, at the “target” performance level); and (2) each award (including any award or portion thereof that,
by its terms, does not accelerate and vest in the circumstances) shall terminate upon the related event; provided that the holder of an option or SAR shall be given reasonable advance notice of the impending termination and a reasonable opportunity
to exercise his or her outstanding vested options and SARs (after giving effect to any accelerated vesting required in the circumstances) in accordance with their terms before the termination of such awards (except that in no case shall more than
ten days’ notice of the impending termination be required and any acceleration of vesting and any exercise of any portion of an award that is so accelerated may be made contingent upon the actual occurrence of the event). 

 

	 	(b)	 Without limiting the preceding paragraph, in connection with any event referred to in the preceding paragraph
or any change in control event defined in any applicable award agreement, the Administrator may, in its discretion, provide for the accelerated vesting of any award or awards as and to the extent determined by the Administrator in the circumstances.

  

	 	(c)	 For purposes of this Section 7.2, an award shall be deemed to have been “assumed” if (without
limiting other circumstances in which an award is assumed) the award continues after an event referred to above in this Section 7.2, and/or is assumed and continued by the surviving entity following such event (including, without limitation, an
entity that, as a result of such event, owns the Corporation or all or substantially all of the Corporation’s assets directly or through one or more subsidiaries (a “Parent”)), and confers the right to purchase or receive, as
applicable and subject to vesting and the other terms and conditions 

  
 13 

	 	
of the award, for each share of Common Stock subject to the award immediately prior to the event, the consideration (whether cash, shares, or other securities or property) received in the event
by the stockholders of the Corporation for each share of Common Stock sold or exchanged in such event (or the consideration received by a majority of the stockholders participating in such event if the stockholders were offered a choice of
consideration); provided, however, that if the consideration offered for a share of Common Stock in the event is not solely the ordinary common stock of a successor corporation or a Parent, the Administrator may provide for the consideration to be
received upon exercise or payment of the award, for each share subject to the award, to be solely ordinary common stock of the successor corporation or a Parent equal in fair market value to the per share consideration received by the stockholders
participating in the event. 

  

	 	(d)	 The Administrator may adopt such valuation methodologies for outstanding awards as it deems reasonable in the
event of a cash or property settlement and, in the case of options, SARs or similar rights, but without limitation on other methodologies, may base such settlement solely upon the excess if any of the per share amount payable upon or in respect of
such event over the exercise or base price of the award. In the case of an option, SAR or similar right as to which the per share amount payable upon or in respect of such event is less than or equal to the exercise or base price of the award, the
Administrator may terminate such award in connection with an event referred to in this Section 7.2 without any payment in respect of such award. 

  

	 	(e)	 In any of the events referred to in this Section 7.2, the Administrator may take such action contemplated
by this Section 7.2 prior to such event (as opposed to on the occurrence of such event) to the extent that the Administrator deems the action necessary to permit the participant to realize the benefits intended to be conveyed with respect to
the underlying shares. Without limiting the generality of the foregoing, the Administrator may deem an acceleration and/or termination to occur immediately prior to the applicable event and, in such circumstances, will reinstate the original terms
of the award if an event giving rise to an acceleration and/or termination does not occur. 

  

	 	(f)	 Without limiting the generality of Section 3.4, any good faith determination by the Administrator pursuant
to its authority under this Section 7.2 shall be conclusive and binding on all persons. 

  

	 	(g)	 The Administrator may override the provisions of this Section 7.2 by express provision in the award
agreement and may accord any Eligible Person a right to refuse any acceleration, whether pursuant to the award agreement or otherwise, in such circumstances as the Administrator may approve. The portion of any ISO accelerated in connection with an
event referred to in this Section 7.2 (or such other circumstances as may trigger accelerated vesting of the award) shall remain exercisable as an ISO only to the extent the applicable $100,000 limitation on ISOs is not exceeded. To the extent
exceeded, the accelerated portion of the option shall be exercisable as a nonqualified stock option under the Code.

	8.	 OTHER PROVISIONS 

 

	 	8.1	 Compliance with Laws. This Plan, the granting and vesting of awards under this Plan, the
offer, issuance and delivery of shares of Common Stock, and/or the payment of money under this Plan or under awards are subject to compliance with all applicable federal, state, local and foreign laws, rules and regulations (including, but not
limited to, state and federal securities law and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Corporation, be necessary or advisable in connection
therewith. The person acquiring any securities under this Plan will, if requested by the Corporation or one of its Subsidiaries, provide such assurances and representations to the Corporation or one of its Subsidiaries as the Administrator may deem
necessary or desirable to assure compliance with all applicable legal and accounting requirements. 

  

	 	8.2	 No Rights to Award. No person shall have any claim or rights to be granted an award (or
additional awards, as the case may be) under this Plan, subject to any express contractual rights (set forth in a document other than this Plan) to the contrary. 

 

	 	8.3	 No Employment/Service Contract. Nothing contained in this Plan (or in any other documents
under this Plan or in any award) shall confer upon any Eligible Person or other participant any right to continue in the employ or other service of the Corporation or one of its Subsidiaries, constitute any contract or agreement of employment or
other service or affect an employee’s status as an employee at will, nor shall interfere in any way with the right of the Corporation or one of its Subsidiaries to change a person’s compensation or other benefits, or to terminate his or
her employment or other service, with or without cause. Nothing in this Section 8.3, however, is intended to adversely affect any express independent right of such person under a separate employment or service contract other than an award
agreement. 

  

	 	8.4	 Plan Not Funded. Awards payable under this Plan shall be payable in shares or from the
general assets of the Corporation, and no special or separate reserve, fund or deposit shall be made to assure payment of such awards. No participant, beneficiary or other person shall have any right, title or interest in any fund or in any specific
asset (including shares of Common Stock, except as expressly otherwise provided) of the Corporation or one of its Subsidiaries by reason of any award hereunder. Neither the provisions of this Plan (or of any related documents), nor the creation or
adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Corporation or one of its Subsidiaries and any participant,
beneficiary or other person. To the extent that a participant, beneficiary or other person acquires a right to receive payment pursuant to any award hereunder, such right shall be no greater than the right of any unsecured general creditor of the
Corporation. 

  
 15 

	 	8.5	 Tax Withholding. Upon any exercise, vesting, or payment of any award, or upon the
disposition of shares of Common Stock acquired pursuant to the exercise of an ISO prior to satisfaction of the holding period requirements of Section 422 of the Code, or upon any other tax withholding event with respect to any award,
arrangements satisfactory to the Corporation shall be made to provide for any taxes the Corporation or any of its Subsidiaries may be required or permitted to withhold with respect to such award event or payment. Such arrangements may include (but
are not limited to) any one of (or a combination of) the following: 

  

	 	(a)	 The Corporation or one of its Subsidiaries shall have the right to require the participant (or the
participant’s personal representative or beneficiary, as the case may be) to pay or provide for payment of the amount of any taxes which the Corporation or one of its Subsidiaries may be required or permitted to withhold with respect to such
award event or payment. 

  

	 	(b)	 The Corporation or one of its Subsidiaries shall have the right to deduct from any amount otherwise payable in
cash (whether related to the award or otherwise) to the participant (or the participant’s personal representative or beneficiary, as the case may be) the amount of any taxes which the Corporation or one of its Subsidiaries may be required or
permitted to withhold with respect to such award event or payment. 

  

	 	(c)	 In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock
under this Plan, the Administrator may in its sole discretion (subject to Section 8.1) require or grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions
as the Administrator may establish, that the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their fair market value or at the sales price in
accordance with authorized procedures for cashless exercises, necessary to satisfy any applicable withholding obligation on exercise, vesting or payment. 

  

	 	8.6	 Effective Date, Termination and Suspension, Amendments. 

8.6.1 Effective Date. This Plan is effective as of June 30, 2020, the date of its approval by the Board (the
“Effective Date”). This Plan shall be submitted for and subject to stockholder approval no later than twelve months after the Effective Date. Unless earlier terminated by the Board and subject to any extension that may be approved
by stockholders, this Plan shall terminate at the close of business on the day before the tenth anniversary of the Effective Date. After the termination of this Plan either upon such stated termination date or its earlier termination by the Board,
no additional awards may be granted under this Plan, but previously granted awards (and the authority of the Administrator with respect thereto, including the authority to amend such awards) shall remain outstanding in accordance with their
applicable terms and conditions and the terms and conditions of this Plan. 

  
 16 

 8.6.2 Board Authorization. The Board may, at any time, terminate or,
from time to time, amend, modify or suspend this Plan, in whole or in part. No awards may be granted during any period that the Board suspends this Plan. 

8.6.3 Stockholder Approval. To the extent then required by applicable law or deemed necessary or advisable by the Board,
any amendment to this Plan shall be subject to stockholder approval. 
 8.6.4 Amendments to Awards. Without limiting any
other express authority of the Administrator under (but subject to) the express limits of this Plan, the Administrator by agreement or resolution may waive conditions of or limitations on awards to participants that the Administrator in the prior
exercise of its discretion has imposed, without the consent of a participant, and (subject to the requirements of Sections 3.2 and 8.6.5) may make other changes to the terms and conditions of awards. Any amendment or other action that would
constitute a repricing of an award is subject to the no-repricing provision of Section 3.3. 

8.6.5 Limitations on Amendments to Plan and Awards. No amendment, suspension or termination of this Plan or amendment of
any outstanding award agreement shall, without written consent of the participant, affect in any manner materially adverse to the participant any rights or benefits of the participant or obligations of the Corporation under any award granted under
this Plan prior to the effective date of such change. Changes, settlements and other actions contemplated by Section 7 shall not be deemed to constitute changes or amendments for purposes of this Section 8.6. 

 

	 	8.7	 Privileges of Stock Ownership. Except as otherwise expressly authorized by the
Administrator, a participant shall not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by the participant. Except as expressly required by Section 7.1 or otherwise
expressly provided by the Administrator, no adjustment will be made for dividends or other rights as a stockholder for which a record date is prior to such date of delivery. 

 

	 	8.8	 Governing Law; Severability. 

8.8.1 Choice of Law. This Plan, the awards, all documents evidencing awards and all other related documents shall be
governed by, and construed in accordance with the laws of the State of Delaware, notwithstanding any Delaware or other conflict of law provision to the contrary. 

8.8.2 Severability. If a court of competent jurisdiction holds any provision invalid and unenforceable, the remaining
provisions of this Plan shall continue in effect. 
  

	 	8.9	 Captions. Captions and headings are given to the sections and subsections of this Plan
solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of this Plan or any provision thereof. 

  
 17 

	 	8.10	 Stock-Based Awards in Substitution for Stock Options or Awards Granted by Other
Corporation. Awards may be granted to Eligible Persons in substitution for or in connection with an assumption of employee stock options, SARs, restricted stock or other stock-based awards granted by other entities to persons who are or who
will become Eligible Persons in respect of the Corporation or one of its Subsidiaries, in connection with a distribution, merger or other reorganization by or with the granting entity or an affiliated entity, or the acquisition by the Corporation or
one of its Subsidiaries, directly or indirectly, of all or a substantial part of the stock or assets of the employing entity. The awards so granted need not comply with other specific terms of this Plan, provided the awards reflect adjustments
giving effect to the assumption or substitution consistent with any conversion applicable to the common stock (or the securities otherwise subject to the award) in the transaction and any change in the issuer of the security. Any shares that are
delivered and any awards that are granted by, or become obligations of, the Corporation, as a result of the assumption by the Corporation of, or in substitution for, outstanding awards previously granted or assumed by an acquired company (or
previously granted or assumed by a predecessor employer (or direct or indirect parent thereof) in the case of persons that become employed by the Corporation or one of its Subsidiaries in connection with a business or asset acquisition or similar
transaction) shall not be counted against the Share Limit or other limits on the number of shares available for issuance under this Plan. 

  

	 	8.11	 Non-Exclusivity of Plan. Nothing in this Plan shall limit or be deemed to limit the
authority of the Board or the Administrator to grant awards or authorize any other compensation, with or without reference to the Common Stock, under any other plan or authority. 

 

	 	8.12	 No Corporate Action Restriction. The existence of this Plan, the award agreements and the
awards granted hereunder shall not limit, affect, or restrict in any way the right or power of the Corporation or any Subsidiary (or any of their respective shareholders, boards of directors or committees thereof (or any subcommittees), as the case
may be) to make or authorize: (a) any adjustment, recapitalization, reorganization or other change in the capital structure or business of the Corporation or any Subsidiary, (b) any merger, amalgamation, consolidation or change in the
ownership of the Corporation or any Subsidiary, (c) any issue of bonds, debentures, capital, preferred or prior preference stock ahead of or affecting the capital stock (or the rights thereof) of the Corporation or any Subsidiary, (d) any
dissolution or liquidation of the Corporation or any Subsidiary, (e) any sale or transfer of all or any part of the assets or business of the Corporation or any Subsidiary, (f) any other award, grant, or payment of incentives or other
compensation under any other plan or authority (or any other action with respect to any benefit, incentive or compensation), or (g) any other corporate act or proceeding by the Corporation or any Subsidiary. No participant, beneficiary or any
other person shall have any claim under any award or award agreement against any member of the Board or the Administrator, or the Corporation or any employees, officers or agents of the Corporation or any Subsidiary, as a result of any such action.
Awards need not be structured so as to be deductible for tax purposes. 

  
 18 

	 	8.13	 Other Company Benefit and Compensation Programs. Payments and other benefits received by a
participant under an award made pursuant to this Plan shall not be deemed a part of a participant’s compensation for purposes of the determination of benefits under any other employee welfare or benefit plans or arrangements, if any, provided
by the Corporation or any Subsidiary, except where the Administrator expressly otherwise provides or authorizes in writing. Awards under this Plan may be made in addition to, in combination with, as alternatives to or in payment of grants, awards or
commitments under any other plans, arrangements or authority of the Corporation or its Subsidiaries. 

  

	 	8.14	 Clawback Policy. The awards granted under this Plan are subject to the terms of the
Corporation’s recoupment, clawback or similar policy as it may be in effect from time to time, as well as any similar provisions of applicable law, any of which could in certain circumstances require repayment or forfeiture of awards or any
shares of Common Stock or other cash or property received with respect to the awards (including any value received from a disposition of the shares acquired upon payment of the awards).
