 Exhibit 10.36 

BLEND BIOSCIENCES, INC. 

2011 Stock Incentive Plan 

1.        Purpose. 

The purpose of this plan (the “Plan”) is to secure for Blend Biosciences, Inc., a Delaware corporation (the “Company”) and
its shareholders the benefits arising from capital stock ownership by employees, officers and directors of, and consultants or advisors to, the Company and its parent and subsidiary corporations who are expected to contribute to the Company’s
future growth and success. Under the Plan recipients may be awarded both (i) Options (as defined in Section 2.1) to purchase the Company’s common stock, par value $0.0001 (“Common Stock”) and (ii) shares of Common Stock
(“Restricted Stock Awards”). Except where the context otherwise requires, the term “Company” shall include any parent and all present and future subsidiaries of the Company as defined in Sections 424(e) and 424(f) of the Internal
Revenue Code of 1986, as amended or replaced from time to time (the “Code”). Those provisions of the Plan which make express reference to Section 422 of the Code shall apply only to Incentive Stock Options (as that term is defined
below). Appendix A to this Plan shall apply only to participants in the Plan who are residents of the State of California. 

2.        Types of Awards and Administration. 

2.1        Options. Options granted pursuant to the Plan (“Options”) shall be
authorized by action of the Board of Directors of the Company (the “Board” or “Board of Directors”) and may be either incentive stock options (“Incentive Stock Options”) meeting the requirements of Section 422 of
the Code or non-statutory Options which are not intended to meet the requirements of Section 422. All Options when granted are intended to be non-statutory Options,
unless the applicable Option Agreement (as defined in Section 5.1) explicitly states that the Option is intended to be an Incentive Stock Option. The vesting of Options may be conditioned upon the completion of a specified period of employment
with the Company and/or such other conditions or events as the Board may determine. The Board may also provide that Options are immediately exercisable subject to certain repurchase rights in the Company dependent upon the continued employment of
the optionee and/or such other conditions or events as the Board may determine. 
 2.1.1    Incentive Stock Options.
Incentive Stock Options may only be granted to employees of the Company. For so long as the Code shall so provide, Options granted to any employee under the Plan (and any other incentive stock option plans of the Company) which are intended to
constitute Incentive Stock Options shall not constitute Incentive Stock Options to the extent that such Options, in the aggregate, become exercisable for the first time in any one calendar year for shares of Common Stock with an aggregate fair
market value (determined as of the respective date or dates of grant) of more than $100,000. If an Option is intended to be an Incentive Stock Option, and if for any reason such Option (or any portion thereof) shall not qualify as an Incentive Stock
Option, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a non-statutory Option appropriately granted under the Plan provided that such Option (or portion
thereof) otherwise meets the Plan’s requirements relating to non-statutory Options. 












 2.2        Restricted Stock Awards. The
Board in its discretion may grant Restricted Stock Awards, entitling the recipient to acquire, for a purchase price determined by the Board, shares of Common Stock subject to such restrictions and conditions as the Board may determine at the time of
grant (“Restricted Stock”), including continued employment and/or achievement of pre-established performance goals and objectives. 

2.3        Administration. The Plan shall be administered by the Board, whose construction and
interpretation of the terms and provisions of the Plan shall be final and conclusive. The Board may in its sole discretion authorize issuance of Restricted Stock, the grant of Options and the issuance of shares upon exercise of such Options as
provided in the Plan. The Board shall have authority, subject to the express provisions of the Plan, to construe Restricted Stock Agreements, Option Agreements and the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan,
to determine the terms and provisions of Restricted Stock Agreements and Option Agreements, and to make all other determinations in the judgment of the Board necessary or desirable for the administration of the Plan. The Board may correct any defect
or supply any omission or reconcile any inconsistency in the Plan or in any Restricted Stock Agreement or Option Agreement in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge
of such expediency. No director or person acting pursuant to authority delegated by the Board shall be liable for any action or determination under the Plan made in good faith. The Board may, to the full extent permitted by or consistent with
applicable laws or regulations, delegate any or all of its powers under the Plan to a committee (the “Committee”) appointed by the Board, and if the Committee is so appointed, to the extent of such delegation, all references to the Board
in the Plan shall mean and relate to such Committee, other than references to the Board in this sentence and in Section 18 (as to amendment or termination of the Plan) and Section 22. 

3.        Eligibility. 

Options may be granted, and Restricted Stock may be issued, to persons who are, at the time of such grant or issuance, employees, officers or
directors of, or consultants or advisors to, the Company; provided, that the class of persons to whom Incentive Stock Options may be granted shall be limited to employees of the Company. 

3.1        10% Shareholder. If any employee to whom an Incentive Stock Option is to be granted
is, at the time of the grant of such Option, the owner of stock possessing more than 10% of the total combined voting power of all classes of stock of the Company (after taking into account the attribution of stock ownership rules of
Section 424(d) of the Code) (a “Greater Than 10% Shareholder”), any Incentive Stock Option granted to such individual must: (i) have an exercise price per share of not less than 110% of the fair market value of one share of
Common Stock at the time of grant; and (ii) expire by its terms not more than five years from the date of grant. 

4.        Stock Subject to Plan. 

Subject to adjustment as provided in Section 14.2 below, the maximum number of shares of Common Stock which may be issued under the Plan
is 400,000 shares. If an Option shall expire or terminate for any reason without having been exercised in full, the unpurchased shares 

  
 - 2 - 













 
Subject to such Option shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan. If shares of Restricted Stock shall be forfeited to, or otherwise
repurchased by, the Company pursuant to a Restricted Stock Agreement, such repurchased Shares shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan. If shares issued upon exercise of an Option are tendered
to the Company in payment of the exercise price of an Option, such tendered shares shall again be available for subsequent Option grants or Restricted Stock Awards under the Plan. 

5.        Forms of Restricted Stock Agreements and Option Agreements. 

5.1        Option Agreement. Each recipient of an Option shall execute an option agreement
(“Option Agreement”) in such form not inconsistent with the Plan as may be    approved by the Board of Directors.    Such Option Agreements may differ among recipients 

5.2        Restricted Stock Agreement. Each recipient of a grant of Restricted Stock shall
execute an agreement (“Restricted Stock Agreement”) in such form not inconsistent with the Plan as may be approved by the Board of Directors. Such Restricted Stock Agreements may differ among recipients. 

5.3        “Lock-Up” Agreement. Unless the
Board specifies otherwise, each Restricted Stock Agreement and Option Agreement shall provide that upon the request of the Company or the managing underwriter(s) of any offering of securities of the Company that is the subject of a registration
statement filed under the United States Securities Act of 1933, as amended from time to time (the “Act”), the holder of any Option or the purchaser of any Restricted Stock shall, in connection therewith, agree in writing (in such form as
the Company or such managing underwriter(s) shall request) to the general effect that for a period of time (not to exceed 180 days, plus such additional number of days (not to exceed 35) as may reasonably be requested to enable the underwriter(s) of
such offering to comply with Rule 2711(f) of the Financial Industry Regulatory Authority or any amendment or successor thereto) from the effective date of the registration statement under the Act for such offering, the holder or purchaser will not
sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any shares of the common stock of the Company owned or controlled by him or her. 

6.        Purchase Price. 

6.1        General. The purchase price per share of Restricted Stock and per share of stock
deliverable upon the exercise of an Option shall be determined by the Board, provided, however, that in the case of any Option, the exercise price shall not be less than 100% of the fair market value of such stock, as determined by the Board, at the
time of grant of such Option, or less than 110% of such fair market value in the case of any Incentive Stock Option granted to a Greater Than 10% Shareholder. 

6.2        Payment of Purchase Price. Option Agreements may provide for the payment of the
exercise price by delivery of cash or a check to the order of the Company in an amount equal to the exercise price of such Options, or, to the extent provided in the applicable Option Agreement, by one of the following methods: 

  
 - 3 - 













 (i)  with the consent of the Board, by delivery to the Company of
shares of Common Stock; such surrendered shares shall have a fair market value equal in amount to the exercise price of the Options being exercised, 

(ii)  with the consent of the Board, a personal recourse note issued by the optionee to the Company in a principal
amount equal to such aggregate exercise price and with such other terms, including interest rate and maturity, as the Company may determine in its discretion; provided, however, that the interest rate borne by such note shall not be less than the
lowest applicable federal rate, as defined in Section I274(d) of the Code, 
 (iii)  with the consent of the
Board, if the class of Common Stock is registered under the Securities Exchange Act of 1934 at such time, subject to rules as may be established by the Board, by delivery to the Company of a properly executed exercise notice along with irrevocable
instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price, 

(iv)  with the consent of the Board, by reducing the number of Option shares otherwise issuable to the optionee
upon exercise of the Option by a number of shares of Common Stock having a fair market value equal to such aggregate exercise price, 

(v)  with the consent of the Board, by any combination of such methods of payment. 

The fair market value of any shares of Common Stock or other non-cash consideration which may be
delivered upon exercise of an Option shall be determined by the Board of Directors. Restricted Stock Agreements may provide for the payment of any purchase price in any manner approved by the Board of Directors at the time of authorizing the
issuance thereof. 
 7.        Option Period. 

Notwithstanding any other provision of the Plan or any Option Agreement, each Option and all rights thereunder shall expire on the date
specified in the applicable Option Agreement, provided that such date shall not be later than ten years after the date on which the Option is granted (or five years in the case of an Incentive Stock Option granted to a Greater Than 10% Shareholder),
and in either case, shall be subject to earlier termination as provided in the Plan or Option Agreement. 

8.        Exercise of Options. 

8.1        General. Each Option shall be exercisable either in full or in installments at such
time or times and during such period as shall be set forth in the Option Agreement evidencing such Option, subject to the provisions of the Plan. To the extent not exercised, installments shall accumulate and be exercisable, in whole or in part, at
any time after becoming exercisable, but not later than the date the Option expires. 

  
 - 4 - 













 8.2        Notice of Exercise. An Option may
be exercised by the optionee by delivering to the Company on any business day a written notice specifying the number of shares of Common Stock the optionee then desires to purchase and specifying the address to which the certificates for such shares
are to be mailed (the “Notice”), accompanied by payment for such shares. In addition, the Company may require any individual to whom an Option is granted, as a condition of exercising such Option, to give written assurances (the
“Investment Letter”) in a substance and form satisfactory to the Company to the effect that such individual is acquiring the Common Stock subject to the Option for his or her own account for investment and not with a view to the resale or
distribution thereof, and to such other effects as the Company deems necessary or advisable in order to comply with any securities law(s). 

8.3        Delivery. As promptly as practicable after receipt of the Notice, the Investment
Letter (if required) and payment, the Company shall deliver or cause to be delivered to the optionee certificates for the number of shares with respect to which such Option has been so exercised, issued in the optionee’s name; provided,
however, that such delivery shall be deemed effected for all purposes when the Company or a stock transfer agent shall have deposited such certificates in the United States mail, addressed to the optionee, at the address specified in the Notice.

 9.        Transferability of Options.    No Incentive Stock
Option shall be assignable or transferable by the person to whom it is granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and during the life of an optionee, an Incentive Stock Option shall be
exercisable only by the optionee. The Board may, in its discretion, determine the extent to which a non-statutory Option shall be transferable. 

10.      Termination of Employment; Disability; Death. Except as may be otherwise expressly
provided in the terms and conditions of the Option Agreement, Options shall terminate on the earliest to occur of: 
  

	 	(i)	 the date of expiration thereof; 



 

	 	(ii)	 90 days after termination of the optionee’s employment with, or provision of services to, the Company by
the Company for Cause (as hereinafter defined); 


  

	 	(iii)	 90 days after the date of voluntary termination of the optionee’s employment with, or provision of
services to, the Company by the optionee (other than for death or permanent disability as defined below); or 


  

	 	(iv)	 90 days after the date of termination of the optionee’s employment with, or provision of services to, the
Company by the Company without Cause (other than for death or permanent disability as defined below). 


 Until the date on which the
Option so expires, the optionee may exercise that portion of his or her Option which is exercisable at the time of termination of the employment or service relationship. 

  
 - 5 - 













 An employment or service relationship between the Company and the optionee shall be deemed
to exist during any period during which the optionee is employed by or providing services to the Company. Whether an authorized leave of absence or an absence due to military    or government service shall constitute termination
of the employment relationship between the Company and the optionee shall be determined by the Board at the time     thereof. 

For purposes of this Section 10, the term “Cause” shall mean (a) any material breach by the optionee of any agreement to
which the optionee and the Company are both parties, (b) any act (other than retirement) or omission to act by the optionee which may have a material and adverse effect on the Company’s business or on the optionee’s ability to perform
services for the Company, including, without limitation, the commission of any crime (other than minor traffic violations), or (c) any material misconduct or material neglect of duties by the optionee in connection with the business or affairs
of the Company. An optionee’s employment shall be deemed to have been terminated for Cause if the Company determines within thirty (30) days of the termination of employment (whether such termination was voluntary or involuntary) that
termination for Cause was warranted. 
 In the event of the permanent and total disability or death of an optionee while in an employment or
other relationship with the Company, any Option held by such optionee shall terminate on the earlier of the date of expiration of the Option or one (1) year following the date of such disability or death. After disability or death, the optionee
(or in the case of death, his or her executor, administrator or any person or persons to whom this option may be transferred by will or by laws of descent and distribution) shall have the right, at any time prior to such termination of an Option, to
exercise the Option to the extent the optionee was entitled to exercise such Option as of the date of his or her disability or death. An optionee is permanently and totally disabled if he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment which can be expected to last for a continuous period of not less than 12 months; permanent and total disability shall be determined in accordance with
Section 22(e)(3) of the Code and the regulations issued thereunder. 

11.        Rights as a Shareholder. The holder of an Option shall have no rights as a
shareholder with respect to any shares covered by the Option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a
stock certificate to him or her for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 

12.        Additional Provisions. The Board of Directors may, in its sole discretion,
include additional provisions in Restricted Stock Agreements and Option Agreements, including, without limitation, restrictions on transfer, rights of the Company to repurchase shares of    Restricted Stock or shares of Common
Stock acquired upon exercise of Options, commitments to pay cash bonuses, to make, arrange for or guaranty loans or to transfer other property to    optionees upon exercise of Options, or such other provisions as shall be
determined by the Board of Directors; provided that such additional provisions shall not be inconsistent with any other    term or condition of the Plan and such additional provisions shall not be such as to cause any
Incentive Stock Option to fail to qualify as an Incentive Stock Option within the meaning of    Section 422 of the Code. 

  
 - 6 - 













 13.        Acceleration, Extension, Etc. The
Board of Directors may, in its sole discretion, (i) accelerate the date or dates on which all or any particular Option or Options may be exercised or (ii) extend the period or periods of time during which all, or any particular, Option or
Options may be exercised. 
 14.        Adjustment Upon Changes in Capitalization 

14.1        No Effect of Options upon Certain Corporate Transactions. The existence of
outstanding Options shall not affect in any way the right or power of the Company to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger
or consolidation, or any issue of Common Stock, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 

14.2        Adjustment Provisions. If, through or as a result of any merger, consolidation,
sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are
increased, decreased or exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other
non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment shall be made in (x) the maximum number and kind of shares
reserved for issuance under the Plan, (y) the number and kind of shares or other securities subject to any then outstanding Options, and (z) the price for each share or other security subject to any then outstanding Options, so that upon
exercise of such Options, in lieu of the shares of Common Stock for which such Options were then exercisable, the relevant optionee shall be entitled to receive, for the same aggregate consideration, the same total number and kind of shares or other
securities, cash or property that the owner of an equal number of outstanding shares of Common Stock immediately prior to the event requiring adjustment would own as a result of the event. If any such event. Shall occur, appropriate adjustment shall
also be made in the application of the provisions of this Section 14 and Section 15 with respect to Options and the rights of optionees after the event so that the provisions of such Sections shall be applicable after the event and be as
nearly equivalent as practicable in operation after the event as they were before the event. 

14.3        No Adjustment in Certain Cases. Except as hereinbefore expressly provided, .the
issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property or for labor or services, either upon direct sale or upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock
then subject to outstanding options. 
 14.4        Board Authority to Make Adjustments. Any
adjustments under this Section 14 will be made by the Board of Directors, whose determination as to what adjustments, 

  
 - 7 - 













 
if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued under the Plan on account of any such adjustments 

15.        Effect of Certain Transactions 

15.1        General. Except as provided in any Option Agreement or Restricted Stock Agreement
to the contrary, if the Company is merged with or into or consolidated with another corporation under circumstances where the stockholders of the Company immediately prior to such merger or consolidation do not own after such merger or consolidation
shares representing at least fifty percent (50%) of the voting power of the Company or the surviving or resulting corporation, as the case may be, or if shares representing fifty percent (50%) or more of the voting power of the Company are
transferred to an Unrelated Third Party, as hereinafter defined, or if the Company is liquidated, or sells or otherwise disposes of all or substantially all its assets (each such transaction is referred to herein as a “Change in Control
Transaction”), the Board, or the board of directors of any corporation assuming the obligations of the Company, may, in its discretion, take any one or more of the following action , as to some or all outstanding Options or Restricted Stock
Awards (and need not take the same action as to each such Option or Restricted Stock Award): (i) provide that such Options shall be assumed, or equivalent Options shall be substituted, by the acquiring or succeeding corporation (or an affiliate
thereof), provided that any such Options substituted for Incentive Stock Options shall meet the requirements of Section 424(a) of the Code, (ii) upon written notice to the optionees, provide that all .unexercised Options will
terminate immediately prior to the consummation of the Change in Control Transaction unless exercised by the optionee to the extent otherwise then exercisable within a specified period following the date of such notice, (iii) upon written
notice to the grantees, provide that all unvested shares of Restricted Stock shall be repurchased at cost, (iv) make or provide for a cash payment to the optionees equal to the difference between (A) the fair market value of the per share
consideration (whether cash, securities or other property or any combination of the above) the holder of a share of Common Stock will receive upon consummation of the Change in Control Transaction (the “Per Share Transaction Price”) times
the number of shares of Common Stock subject to outstanding vested Options (to the extent then exercisable at prices not equal to or in excess of the Per Share Transaction Price) and (B) the aggregate exercise price of such outstanding vested
Options, in exchange for the termination of such Options, or (v) provide that all or any outstanding Options shall become exercisable and all or any outstanding Restricted Stock Awards shall vest in part or in full immediately prior to such
event. To the extent that any Options are exercisable at a price equal to or in excess of the Per Share Transaction Price, the Board may provide that such Options shall terminate immediately upon the consummation of the Change in Control Transaction
without any payment being made to the holders of such Options. “Unrelated Third Party” shall mean any person who is not, on the date of adoption of this Plan by the Board, a holder of stock of any class or preference or any stock
option of the Company. 
 15.2        Substitute Options. The Company may grant Options in
substitution for options held by employees, officers or directors of, or consultants or advisors to, another corporation who become employees, officers or directors of, or consultants or advisors to, the Company, as the result of a merger or
consolidation of the employing corporation with the Company or as a result of the acquisition by the Company of property or stock of the employing 

  
 - 8 - 













 
corporation. The Company may direct that substitute Options be granted on such terms and conditions as the Board considers appropriate in the circumstances. 

15.3        Restricted Stock. In the event of a business combination or other transaction of
the type detailed in Section 15.1, any securities, cash or other property received in exchange for shares of Restricted Stock shall continue to be governed by the provisions of any Restricted Stock Agreement pursuant to which they were issued,
including any provision regarding vesting, and such securities, cash, or other property may be held in escrow on such terms as the Board of Directors may direct, to insure compliance with the terms of any such Restricted Stock Agreement. 

16.        No Special Employment Rights. Nothing contained in the Plan or in any Option
Agreement or Restricted Stock Agreement shall confer upon any optionee or holder of Restricted Stock any right with respect to the continuation of his or her employment by the Company or interfere in any way with the right of the Company at any time
to terminate such employment or to increase or decrease his or her compensation. 

17.        Other Employee Benefits. The amount of any compensation deemed to be received
by an employee as a result of the issuance of shares of Restricted Stock or the grant or exercise of an Option or the sale of shares received upon issuance of a Restricted Stock Award or exercise of an Option will not constitute compensation with
respect to which any other employee benefits of such employee are determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined
by the Board of Directors. 
 18.        Amendment of the Plan. 

18.1        The Board may at any time, and from time to time, modify or amend in any respect or
terminate the Plan. If shareholder approval is not obtained within twelve months after any amendment increasing the number of shares authorized under the Plan or changing the class of persons eligible to receive Options under the Plan, no Options
granted pursuant to such amendments shall be deemed to be Incentive Stock Options and no Incentive Stock Options shall be issued pursuant to such amendments thereafter. 

18.2        The termination or any modification or amendment of the Plan shall not, without the
consent of an optionee or the holder of Restricted Stock, adversely affect his or her rights under an Option or Restricted Stock Award previously granted to him or her. With the consent of the recipient of Restricted Stock or optionee affected, the
Board may amend outstanding Restricted Stock Agreements or Option Agreements in a manner not inconsistent with the Plan. 

19.      Withholding. The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee or recipient of Restricted Stock, any federal, state or local taxes of any kind required by law to be withheld with respect to issuance of any shares of Restricted Stock or shares issued upon exercise of Options. Prior
to delivery of any Common Stock pursuant to the terms of this Plan, the Board has the right to require that the optionee or recipient of Restricted Stock remit to the Company an amount sufficient to satisfy any minimum


  
 - 9 - 













 
tax withholding obligation. Subject to the prior approval of the Company, which may be withheld by the Company in its sole discretion, the obligor may elect to satisfy any minimum withholding
obligations, in whole or in part, (i) by causing the Company to withhold shares of Common Stock otherwise issuable, or (ii) by delivering to the Company a sufficient number of shares of Common Stock. The shares so withheld shall have a
fair market value equal to such minimum withholding obligation. The fair market value of the shares used to satisfy such minimum withholding obligation shall be determined by the Company as of the date that the amount of tax to be withheld is to be
determined. A person who has made an election pursuant to this Section 19 may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any repurchase, forfeiture, unfulfilled vesting or other
similar restrictions. 
 20.        Effective Date and Duration of the Plan. 

20.1        Effective Date. The Plan shall become effective when adopted by the Board of
Directors. If shareholder approval is not obtained within twelve months after the date of the Board’s adoption of the Plan, no Options previously granted under the Plan shall be deemed to be Incentive Stock Options and no Incentive Stock
Options shall be granted thereafter. Amendments to the Plan not requiring shareholder approval shall become effective when adopted by the Board. Amendments requiring shareholder approval shall become effective when adopted by the Board, but if
shareholder approval is not obtained within twelve months of the Board’s adoption of such amendment, any Incentive Stock Options granted pursuant to such amendment shall be deemed to be non-statutory
Options provided that such Options are authorized by the Plan. Subject to this limitation, Options may be granted under the Plan at any time after the effective date and before the date fixed for termination of the Plan. 

20.2        Termination. Unless sooner terminated by action of the Board of Directors, the
Plan shall terminate upon the close of business on the day next preceding the tenth anniversary of the date of its adoption by the Board of Directors. 

21.        Provision for Foreign Participants. The Board of Directors may, without
amending the Plan, modify the terms of Option Agreements or Restricted Stock Agreements to differ from those specified in the Plan with respect to participants who are foreign nationals or employed outside the United States to recognize differences
in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters. 

  
 - 10 - 













 22.      Requirements of Law. The Company shall
not be required to sell or issue any shares under any Option or Restricted Stock Award if the issuance of such shares shall constitute a violation by the optionee, the Restricted Stock Award recipient, or by the Company of any provision of any law
or regulation of any governmental authority. In addition, in connection with the Act, the Company shall not be required to issue any shares upon exercise of any Option unless the Company has received evidence satisfactory to it to the effect that
the holder of such Option will not transfer such shares except pursuant to a registration statement in effect under the Act or unless an opinion of counsel satisfactory to the Company has been received by the Company to the effect that such
registration is not required in connection with any such transfer. Any determination in this connection by the Board shall be final, binding and conclusive. In the event the shares issuable on exercise of an Option are not registered under the Act
or under the securities laws of each relevant state or other jurisdiction, the Company may imprint on the certificate(s) appropriate legends that counsel for the Company considers necessary or advisable to comply with the Act or any such state or
other securities law. The Company may register, but in no event shall be obligated to register, any securities covered by the Plan pursuant to the Act; and in the event any shares are so registered the Company may remove any legend on certificates
representing such shares. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option, the grant of any Restricted Stock Award or the issuance of shares pursuant thereto to comply with any law or
regulation of any governmental authority. 
 23.      Conversion of Incentive Stock Options into Non-Qualified Options; Termination. The Board of Directors, with the consent of any optionee, may in its discretion take such actions as may be necessary to convert such optionee’s Incentive Stock Options
(or any installments or portions of installments thereof) that have not been exercised on the date of conversion into non-statutory Options at any time prior to the expiration of such Incentive Stock Options,
regardless of whether the optionee is an employee of the Company or a parent or subsidiary of the Company at the time of such conversion. At the time of such conversion, the Board of Directors (with the consent of the optionee) may impose such
conditions on the exercise of the resulting non-statutory Options as the Board of Directors in its discretion may determine, provided that such conditions shall not be inconsistent with this Plan. Nothing in
this Plan shall be deemed to give any optionee the right to have such optionee’s Incentive Stock Options converted into non-statutory Options, and no such conversion shall occur until and unless the Board
of Directors takes appropriate action. The Board of Directors, with the consent of the optionee, may also terminate any portion of any Incentive Stock Option that has not been exercised at the time of such termination. 

24.      Non-Exclusivity of this Plan; Non-Uniform Determinations. Neither the adoption of this Plan by the Board of Directors nor the approval of this Plan by the stockholders of the Company shall be construed as creating any limitations on the
power of the Board of Directors to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either applicable
generally or only in specific cases. 
 The determinations of the Board of Directors under this Plan need not be uniform and may be made by
it selectively among persons who receive or are eligible to receive Options or Restricted Stock Awards under this Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Board of Directors
shall be entitled, among

other things, to make non-uniform and selective determinations, and to enter into non-uniform and selective Option
Agreements and Restricted Stock Agreements, as to (a) the persons to receive Options or Restricted Stock Awards under this Plan, (b) the terms and provisions of Options or Restricted Stock Awards, (c) the exercise by the Board of
Directors of its discretion in respect of the exercise of Options pursuant to the terms of this Plan, and (d) the treatment of leaves of absence pursuant to Section 10 hereof. 

25.      Governing Law. This Plan and each Option or Restricted Stock Award shall be governed by
the laws of Massachusetts, without regard to its principles of conflicts of law.

 APPENDIX A 

TO BLEND BIOSCIENCES, INC. 2011 STOCK INCENTIVE PLAN 

FOR CALIFORNIA RESIDENTS ONLY 

This Appendix to the Blend Biosciences, Inc. 2011 Stock Incentive Plan (the “Plan”) shall have application only to participants in
the Plan who are residents of the State of California. Capitalized terms contained herein shall have the same meanings given to them in the Plan, unless otherwise provided in this Appendix. Notwithstanding any provision contained in the Plan to
the contrary and to the extent required by applicable law, the following terms and conditions shall apply to all Options and Restricted Stock Awards (collectively “Awards”) granted to residents of the State of California, until such
time as the Common Stock becomes subject to registration under the Securities Act of 1933: 

1.        Awards shall be nontransferable other than by will or the laws of descent and distribution.
Notwithstanding the foregoing, and to the extent permitted by Section 422 of the Code, the Board, in its discretion, may permit distribution of an Award to an inter vivos or testamentary trust in which the Award is to be passed to beneficiaries
upon the death of the trustor (settlor), or by gift to “immediate family” as that term is defined in Rule 16a-l(e) of the United States Exchange Act of 1934. 

2.        Unless employment is terminated for Cause, the right to exercise an Option in the event of
termination of employment, to the extent that the optionee is otherwise entitled to exercise an Option on the date employment terminates, shall be 

(a)        at least six months from the date of termination of employment if termination was caused
by death or permanent disability; and 
 (b)        at least 30 days from the date of termination
if termination of employment was caused by other than death or permanent disability; 

(c)        but in no event later than the remaining term of the Option. 

3.        Any Award exercised before shareholder approval is obtained shall be rescinded if
shareholder approval is not obtained within 12 months of the Board’s adoption of the Plan.
