SHATTUCK LABS, INC. 

2020 EMPLOYEE STOCK PURCHASE PLAN 

Section 1. PURPOSE 
 The purpose of
this Employee Stock Purchase Plan (the “Plan”) is to provide an opportunity for Employees of Shattuck Labs, Inc., a Delaware corporation (“Sponsor”) and its Participating Subsidiaries (collectively Sponsor and its

objectives in the determination of the Committee, which sub-plans shall not be required to comply with the requirements of Section 423 of the Code or all of the specific provisions of the Plan,

shall be eligible to participate in the Plan with respect to such Offering Period and future Offering Periods, provided that the Committee may establish administrative rules requiring that employment commence some minimum period (not to exceed 90
days) prior to an Enrollment Period and/or that customary employment exceed a specified number of hours or period during a calendar year (which will be no less than 20 hours per week or 5 months in a calendar year) to be eligible to participate with
respect to the associated Offering Period. The Committee may also determine that a designated group of highly compensated Employees is ineligible to participate in the Plan so long as the excluded category fits within the definition of “highly

Subsidiaries, possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of Sponsor or of any of its Subsidiaries. All Employees who participate in the Plan shall have the same rights and privileges
under the Plan, except for differences that may be mandated by local law and that are consistent with Code Section 423(b)(5); provided that individuals participating in a sub-plan adopted pursuant to
Section 16 which is not designed to qualify under Code Section 423 need not have the same rights and privileges as Employees participating in the Code Section 423 Plan. 

Section 4. OFFERING PERIODS 
 The
Plan shall be implemented by a series of Offering Periods, which shall possess terms specified by the Committee in accordance with the terms of the Plan. Offering Periods shall continue until the Plan is terminated pursuant to Section 14
hereof. Once established, the Committee shall have the authority to change the frequency and/or duration of Offering Periods (including the Commencement Dates thereof) with respect to future Offering Periods if such change is announced prior to the
scheduled occurrence of the Enrollment Period for the first Offering Period to be affected thereafter. If the Committee does not establish different rules with respect to an Offering Period, then the duration of an Offering Period shall be six
(6) months and there shall be no overlapping Offering Periods. 
 Section 5. PARTICIPATION 

(a) An Employee who is eligible to participate in the Plan in accordance with its terms at the beginning of an Enrollment Period for an
Offering Period and elects to participate in 

  
 4 

 
such Offering Period shall automatically receive an option in accordance with Section 8(a). Such an Employee shall become a Participant by completing and submitting, on or before the date
prescribed by the Committee with respect to a given Offering Period, a completed payroll deduction authorization and Plan enrollment form provided by Sponsor or its Participating Subsidiaries or by following an electronic or other enrollment process
as prescribed by the Committee. An eligible Employee may authorize payroll deductions at the rate of any whole percentage of the Employee’s Compensation, not to be less than one percent (1.0%) and not to exceed fifteen percent (15.0%) of the
Employee’s Compensation (or such other percentages as the Committee may establish from time to time before an Enrollment Period for a future Offering Period) of such Employee’s Compensation on each payday during the Offering Period. All
payroll deductions will be held in a general corporate account or a trust account. No interest shall be paid or credited to the Participant with respect to such payroll deductions. Sponsor shall maintain or cause to be maintained a separate
bookkeeping account for each Participant under the Plan and the amount of each Participant’s payroll deductions shall be credited to such account. A Participant may not make any additional payments into such account, unless payroll deductions
are prohibited under Applicable Law, in which case the provisions of Section 5(b) of the Plan shall apply. 
 (b) Notwithstanding any
other provisions of the Plan to the contrary, in locations where local law prohibits payroll deductions, an eligible Employee may elect to participate through contributions to his or her account under the Plan in a form acceptable to the Committee.
In such event, any such Employees shall be deemed to be participating in a sub-plan, unless the Committee otherwise expressly provides that such Employees shall be treated as participating in the Plan. 

(c) Under procedures and at times established by the Committee, a Participant may withdraw from the Plan during an Offering Period, by
completing and filing a new payroll deduction authorization and Plan enrollment form with the Company or by following electronic or other procedures prescribed by the Committee. If a Participant withdraws from the Plan during an Offering Period, his
or her accumulated payroll deductions will be refunded to the Participant without interest, his or her right to participate in the current Offering Period will be automatically terminated and no further payroll deductions for the purchase of Common
Stock will be made during the Offering Period. Any Participant who wishes to withdraw from the Plan during an Offering Period, must complete the withdrawal procedures prescribed by the Committee, subject to any rules established by the Committee, or
changes to such rules, pertaining to the timing of withdrawals, limiting the frequency with which Participants may withdraw and re-enroll in the Plan, or imposing a waiting period on Participants wishing to re-enroll following withdrawal. 
 (d) A Participant may not increase his or her rate of contribution
through payroll deductions or otherwise during a given Offering Period. A Participant may decrease his or her rate of contribution through payroll deductions during a given Offering Period during such times specified by the Committee by filing a new
payroll deduction authorization and Plan enrollment form or by following electronic or other procedures prescribed by the Committee. If a Participant has not followed such procedures to change the rate of contribution, the rate of contribution shall
continue at the originally elected rate throughout the Offering Period and future Offering Periods. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) 

  
 5 

 
of the Code for a given calendar year, the Committee may reduce a Participant’s payroll deductions to zero percent (0%) at any time during an Offering Period scheduled to end during such
calendar year. Payroll deductions shall re-commence at the rate provided in such Participant’s enrollment form at the beginning of the first Offering Period which is scheduled to end in the following
calendar year, unless terminated by the Participant as provided in Section 5(c). 
 Section 6. TERMINATION OF EMPLOYMENT 

In the event any Participant terminates employment with Sponsor and its Participating Subsidiaries for any reason (including death) prior to
the expiration of an Offering Period, the Participant’s participation in the Plan shall terminate and all amounts credited to the Participant’s account shall be paid to the Participant or, in the case of death, to the Participant’s
heirs or estate, without interest. Whether a termination of employment has occurred shall be determined by the Committee. If a Participant’s termination of employment occurs within a certain period of time as specified by the Committee (not to
exceed 30 days) prior to the Purchase Date of the Offering Period then in progress, his or her option for the purchase of shares of Common Stock will be exercised on such Purchase Date in accordance with Section 9 as if such Participant were
still employed by the Company. If the Committee does not establish different rules with respect to an Offering Period, then if a Participant’s termination of employment occurs on or after the fifth (5th) day preceding the Purchase Date of an Offering Period, then his or her option for the purchase of shares of Common Stock will be exercised on such Purchase Date in accordance with Section 9 as
if such Participant were still employed by the Company. Following the purchase of shares on such Purchase Date, the Participant’s participation in the Plan shall terminate and all amounts credited to the Participant’s account shall be paid
to the Participant or, in the case of death, to the Participant’s heirs or estate, without interest. The Committee may also establish rules regarding when leaves of absence or changes of employment status will be considered to be a termination
of employment, including rules regarding transfer of employment among Participating Subsidiaries, Subsidiaries and Sponsor, and the Committee may establish
termination-of-employment procedures for this Plan that are independent of similar rules established under other benefit plans of Sponsor and its Subsidiaries; provided
that such procedures are not in conflict with the requirements of Section 423 of the Code. 
 Section 7. STOCK 

Subject to adjustment as set forth in Section 11 and the “evergreen” provision in this Section 7, the aggregate number of
shares of Common Stock which may be issued pursuant to the Plan shall not exceed 395,795 shares (the “Share Reserve”). The Share Reserve will automatically increase on January 1st
of each calendar year, for ten years, commencing on January 1 of the calendar year following the Effective Date, in an amount equal to one percent (1%) of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year. The Board may act prior to January 1st of a given year to provide that there will be no January 1st increase of the Share Reserve for such year or that the increase in the Share Reserve for such year will be a smaller number of shares of Common Stock than would otherwise occur pursuant to the
preceding sentence. 

  
 6 

 Notwithstanding the above, subject to adjustment as set forth in Section 11, the
maximum number of shares of Common Stock that may be issued to any Employee in a given Offering Period shall be 600. The Committee may change this limitation at any time on a prospective basis to apply to future Offering Periods. If, on a given
Purchase Date, the number of shares with respect to which options are to be exercised exceeds either maximum, the Committee shall make, as applicable, such adjustment or pro rata allocation of the shares remaining available for purchase in as
uniform a manner as shall be practicable and as it shall determine to be equitable. 
 Section 8. OFFERING 

(a) On the Commencement Date relating to each Offering Period, each eligible Employee, whether or not such Employee has elected to participate
as provided in Section 5(a), shall be granted an option to purchase that number of whole shares of Common Stock (as adjusted as set forth in Section 11) not to exceed that number of shares of Common Stock determined in accordance with the
last paragraph of Section 7 above (or such lower number of shares as determined by the Committee), which may be purchased with the payroll deductions accumulated on behalf of such Employee during each Offering Period at the purchase price
specified in Section 8(b) below, subject to the additional limitation that no Employee participating in the Plan shall be granted an option to purchase Common Stock under the Plan if such option would permit his or her rights to purchase stock
under all employee stock purchase plans (described in Section 423 of the Code) of Sponsor and its Subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars (USD$25,000) of the Market Value of such Common Stock (determined at
the time such option is granted) for each calendar year in which such option is outstanding at any time. For purposes of the Plan, an option is “granted” on a Participant’s Commencement Date. An option will expire upon the earliest to
occur of (i) the termination of a Participant’s participation in the Plan or such Offering Period, (ii) the beginning of a subsequent Offering Period in which such Participant is participating, or (iii) the termination of the
Offering Period. This Section 8(a) shall be interpreted so as to comply with Code Section 423(b)(8). 
 (b) The Purchase Price
under each option shall be with respect to an Offering Period the lower of (i) a percentage (not less than eighty-five percent (85%)) (“Designated Percentage”) of the Offering Price, or (ii) the Designated Percentage of
the Market Value of a share of Common Stock on the Purchase Date; provided that the Purchase Price may be adjusted by the Committee pursuant to Sections 11 or 12 in accordance with Section 424(a) of the Code. For a given Offering Period, the
Designated Percentage shall be established no later than the beginning of the Enrollment Period for such Offering Period. The Committee may change the Designated Percentage with respect to any future Offering Period, but not to below eighty-five
percent (85%), and the Committee may determine with respect to any prospective Offering Period that the Purchase Price shall be the Designated Percentage of the Market Value of a share of the Common Stock solely on the Purchase Date. If the
Committee does not establish the Designated Percentage prior to the beginning of the Enrollment Period for a given Offering Period, the Designated Percentage for such Offering Period shall be eighty-five percent (85%). 

  
 7 

 Section 9. PURCHASE OF STOCK 

Unless a Participant withdraws from the Plan as provided in Section 5(c), terminates employment prior to the end of an Offering Period as
provided in Section 6, or except as provided in Sections 7, 12 or 14(b), upon the expiration of each Offering Period, a Participant’s option shall be exercised automatically for the purchase of that number of whole shares of Common Stock
which the accumulated payroll deductions credited to the Participant’s account at that time shall purchase at the applicable price specified in Section 8(b) in accordance with the terms of the Plan, including Section 7. If a
Participant’s contributions are collected in a currency other than U.S. Dollars, then unless otherwise provided by the Committee with respect to an Offering Period, such contributions shall be converted into U.S. Dollars using an exchange rate
prevailing on the Purchase Date as selected in the reasonable determination of the Sponsor. Notwithstanding the foregoing, Sponsor or its Participating Subsidiary may make such provisions and take such action as it deems necessary or appropriate for
the withholding of taxes and/or social insurance and/or other amounts which Sponsor or its Participating Subsidiary determines is required by Applicable Law. Each Participant, however, shall be responsible for payment of all individual tax
liabilities arising under the Plan. The shares of Common Stock purchased upon exercise of an option hereunder shall be considered for tax purposes to be sold to the Participant on the Purchase Date. A Participant’s option to purchase shares of
Common Stock hereunder is exercisable only by him or her. 
 Section 10. PAYMENT AND DELIVERY 

As soon as practicable after the exercise of an option, Sponsor shall deliver or cause to have delivered to the Participant a record of the
Common Stock purchased and the balance of any amount of payroll deductions credited to the Participant’s account not used for the purchase of Common Stock, except as specified below. The Committee may permit or require that shares be deposited
directly with a broker designated by the Committee or to a designated agent of the Company, and the Committee may utilize electronic or automated methods of share transfer. The Committee may require that shares be retained with such broker or agent
for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. Sponsor or its Participating Subsidiary shall retain the amount of payroll deductions used to purchase Common
Stock as full payment for the Common Stock and the Common Stock shall then be fully paid and non-assessable. No Participant shall have any voting, dividend, or other Stockholder rights with respect to shares
subject to any option granted under the Plan until the shares subject to the option have been purchased and delivered to the Participant as provided in this Section 10. The Committee may in its discretion direct Sponsor to retain in a
Participant’s account for the subsequent Offering Period any payroll deductions which are not sufficient to purchase a whole share of Common Stock or return such amount to the Participant. Any other amounts left over in a Participant’s
account after a Purchase Date shall be returned to the Participant. If the Committee does not establish different rules with respect to an Offering Period, then all amounts left over in a Participant’s account after a Purchase Date shall be
returned to the Participant.

 Section 11. RECAPITALIZATION 

Subject to any required action by the Stockholders of Sponsor, if there is any change in the outstanding shares of Common Stock or other
securities of Sponsor because of a merger, consolidation, spin-off, reorganization, recapitalization, dividend in property other than cash, extraordinary dividend whether in cash and/or other property, stock
split, reverse stock split, stock dividend, liquidating dividend, combination or reclassification of the Common Stock or other securities (including any such change in the number of shares of Common Stock or other securities effected in connection
with a change in domicile of Sponsor), or any other increase or decrease in the number of shares of Common Stock or other securities effected without receipt of consideration by Sponsor, provided that conversion of any convertible securities of
Sponsor shall not be deemed to have been “effected without receipt of consideration,” the type and number of securities covered by each option under the Plan which has not yet been exercised and the type and number of securities which have
been authorized and remain available for issuance under the Plan, as well as the maximum number of securities which may be purchased by a Participant in an Offering Period, and the price per share covered by each option under the Plan which has not
yet been exercised, shall be appropriately and proportionally adjusted by the Board, and the Board shall take any further actions which, in the exercise of its discretion, may be necessary or appropriate under the circumstances. The Board’s
determinations under this Section 11 shall be conclusive and binding on all parties. 
 Section 12. MERGER, LIQUIDATION, OTHER CORPORATE
TRANSACTIONS 
 (a) In the event of the proposed liquidation or dissolution of Sponsor, the Offering Period will terminate immediately
prior to the consummation of such proposed transaction, unless otherwise provided by the Board in its sole discretion, and all outstanding options shall automatically terminate and the amounts of all payroll deductions will be refunded without
interest to the Participants. 
 (b) In the event of a proposed sale of all or substantially all of the assets of Sponsor, or the merger or
consolidation or similar combination of Sponsor with or into another entity, then in the sole discretion of the Board, (1) each option shall be assumed or an equivalent option shall be substituted by the successor corporation or parent or
subsidiary of such successor entity, (2) on a date established by the Board on or before the date of consummation of such merger, consolidation, combination or sale, such date shall be treated as a Purchase Date, and all outstanding options
shall be exercised on such date, (3) all outstanding options shall terminate and the accumulated payroll deductions will be refunded without interest to the Participants, or (4) outstanding options shall continue unchanged. 

Section 13. TRANSFERABILITY 
 Neither
payroll deductions credited to a Participant’s bookkeeping account nor any rights to exercise an option or to receive shares of Common Stock under the Plan may be voluntarily or involuntarily assigned, transferred, pledged, or otherwise
disposed of in any way, and any attempted assignment, transfer, pledge, or other disposition shall be null and void and without effect. If a Participant in any manner attempts to transfer, assign or otherwise encumber his or her rights or interests
under the Plan, other than as permitted by the Code, such act shall be treated as an election by the Participant to discontinue participation in the Plan pursuant to Section 5(c). 

  
 9 

 Section 14. AMENDMENT OR TERMINATION OF THE PLAN 

(a) The Plan shall continue from the Effective Date until the time that the Plan is terminated in accordance with Section 14(b). 

(b) The Board or the Committee may, in its sole discretion, insofar as permitted by law, terminate or suspend the Plan, or revise or amend it
in any respect whatsoever, except that, without approval of the Stockholders, no such revision or amendment shall increase the number of shares subject to the Plan, other than an adjustment under Section 11 of the Plan, or make other changes
for which Stockholder approval is required under Applicable Law. Upon a termination or suspension of the Plan, the Board may in its discretion (i) return without interest, the payroll deductions credited to Participants’ accounts to such
Participants or (ii) set an earlier Purchase Date with respect to an Offering Period then in progress. 
 Section 15. ADMINISTRATION 

(a) The Board has appointed the Compensation Committee of the Board to administer the Plan (the “Committee”), who will serve
for such period of time as the Board may specify and whom the Board may remove at any time. The Committee will have the authority and responsibility for the day-to-day
administration of the Plan, the authority and responsibility specifically provided in this Plan and any additional duty, responsibility and authority delegated to the Committee by the Board, which may include any of the functions assigned to the
Board in this Plan. The Committee may delegate to a sub-committee and/or to officers or employees of Sponsor the day-to-day
administration of the Plan. As of the Effective Date, the Committee has delegated such day-to-day administrative authority to the Controller. The Committee shall have
full power and authority to adopt, amend and rescind any rules and regulations which it deems desirable and appropriate for the proper administration of the Plan, to construe and interpret the provisions and supervise the administration of the Plan,
to make factual determinations relevant to Plan entitlements and to take all action in connection with administration of the Plan as it deems necessary or advisable, consistent with the delegation from the Board. Decisions of the Committee shall be
final and binding upon all Participants. Any decision reduced to writing and signed by a majority of the members of the Committee shall be fully effective as if it had been made at a meeting of the Committee duly held. The Company shall pay all
expenses incurred in the administration of the Plan. 
 (b) In addition to such other rights of indemnification as they may have as members
of the Board or officers or employees of the Company, members of the Board and of the Committee and their delegates shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily
incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or
any right granted under the Plan, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Sponsor) or paid by them in satisfaction of a judgment in any such
action, suit or 

  
 10 

 
proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct
in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 

Section 16. COMMITTEE RULES FOR JURISDICTIONS OTHER THAN THE UNITED STATES 

The Committee may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements
of the laws and procedures of jurisdictions outside of the United States. Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding handling of payroll deductions or other
contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures and handling of stock certificates which vary with local requirements; however, if such varying provisions
are not in accordance with the provisions of Section 423(b) of the Code, including but not limited to the requirement of Section 423(b)(5) of the Code that all options granted under the Plan shall have the same rights and privileges unless
otherwise provided under the Code and the regulations promulgated thereunder, then the individuals affected by such varying provisions shall be deemed to be participating under a sub-plan and not in the Plan.
The Committee may also adopt sub-plans applicable to particular Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Code
Section 423 and shall be deemed to be outside the scope of Code Section 423 unless the terms of the sub-plan provide to the contrary. The rules of such
sub-plans may take precedence over other provisions of this Plan, with the exception of Section 7, but unless otherwise superseded by the terms of such sub-plan,
the provisions of this Plan shall govern the operation of such sub-plan. The Committee shall not be required to obtain the approval of the Stockholders prior to the adoption, amendment or termination of any sub-plan unless required by the laws of the jurisdiction in which Employees participating in the sub-plan are located. 

Section 17. SECURITIES LAWS REQUIREMENTS 

(a) No option granted under the Plan may be exercised to any extent unless the shares to be issued upon such exercise under the Plan are
covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable provisions of any applicable national, regional, state, local or other jurisdiction, including, without
limitation, the Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, applicable state and foreign securities laws and the requirements of any stock exchange upon which the Shares may then be listed, subject to the
approval of counsel for the Company with respect to such compliance. If on a Purchase Date in any Offering Period hereunder, the Plan is not so registered or in such compliance, options granted under the Plan which are not in material compliance
shall not be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve
(12) months and the Purchase Date shall in no event be more than twenty-seven (27) months from the Commencement Date relating to such Offering Period. If, on the Purchase Date of any offering

  
 11 

 
hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, options granted under the Plan which are not in material compliance shall not be
exercised and all payroll deductions accumulated during the Offering Period (reduced to the extent, if any, that such deductions have been used to acquire shares of Common Stock) shall be returned to the Participants, without interest. The
provisions of this Section 17 shall comply with the requirements of Section 423(b)(5) of the Code to the extent applicable. 
 (b)
As a condition to the exercise of an option, Sponsor may require the person exercising such option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to
sell or distribute such Shares if, in the opinion of counsel for Sponsor, such a representation is required by any of the aforementioned applicable provisions of law. 

Section 18. GOVERNMENTAL REGULATIONS 

This Plan and Sponsor’s obligation to sell and deliver shares of its stock under the Plan shall be subject to the approval of any
governmental authority required in connection with the Plan or the authorization, issuance, sale, or delivery of stock hereunder. 
 Section 19. NO
ENLARGEMENT OF EMPLOYEE RIGHTS 
 Nothing contained in this Plan shall be deemed to give any Employee or other individual the right to be
retained in the employ or service of Sponsor or any Participating Subsidiary or to interfere with the right of Sponsor or Participating Subsidiary to discharge any Employee or other individual at any time, for any reason or no reason, with or
