	Re:	 Offer of Employment 



Dear David: 
 Janux Therapeutics, Inc. (the
“Company”) is pleased to offer you at-will employment in the position of President and Chief Executive Officer on the terms and conditions set forth in this letter agreement (the
“Agreement”). 
 1. Employment by the Company. Your employment with the Company shall begin on January 1,
2021 or such date as otherwise agreed to by you and the Company (such actual date your employment begins (the “Start Date”)). This is an exempt position, and during your employment with the Company, you will devote your best efforts
and substantially all of your business time and attention to the business of the Company, except for approved vacation periods and reasonable periods of illness or other incapacities permitted by the Company’s general employment policies. You
shall perform such duties as are required by the Company’s Board of Directors (“Board”), to whom you will report. Your primary work location shall be the Company’s office located in San Diego, California. The Company
reserves the right to reasonably require you to perform your duties at places other than your primary office location from time to time, and to require reasonable business travel. The Company may modify your job title and duties as it deems
necessary and appropriate in light of the Company’s needs and interests from time to time. 
 2. Compensation. 

2.1 Base Salary. For services to be rendered hereunder, you shall receive a base salary at the rate of $424,408 per year (the
“Base Salary”), subject to standard payroll deductions and withholdings and payable in accordance with the Company’s regular payroll schedule. 

2.2 Annual Bonus. You will be eligible for an annual discretionary bonus with a target amount of 40% of your then current annual
Base Salary, prorated for the number of days employed in a calendar year (the “Annual Bonus”). Whether you receive an Annual Bonus for any given year, and the amount of any such Annual Bonus, will be determined by the Board and/or
its Compensation Committee in its discretion based upon the achievement of corporate and/or individual objectives and milestones that are determined in the sole discretion of the Board. You must continue to be employed through the date the Annual
Bonus is paid in order to earn such bonus. The Annual Bonus, if earned, shall be paid to you in a lump sum no later than March 15th of the calendar year that follows the performance year, subject
to applicable payroll deductions and withholdings.

 3. Reasonable Business Expenses. You will be eligible for reimbursement of all
reasonable, necessary and documented out-of-pocket business, entertainment, and travel expenses incurred by you in connection with the performance of your duties
hereunder in accordance with the Company’s expense reimbursement policies and procedures. 
 4. Vacation; Holidays.
Currently, exempt employees do not accrue vacation. Supervisors will approve paid vacation requests based on the employee’s progress on work goals or milestones, status of projects, fairness to the working team, and productivity and
efficiency of the employee. Since vacation is not allotted or accrued, there is no “unused” vacation time to be carried over from one year to the next nor paid out upon termination. You will also be eligible for certain paid holidays
pursuant to Company policy. The Company reserves the right to cancel or change its policies regarding vacation, paid sick leave and/or holidays from time to time without amendment of this Agreement. 

5. Company Policies; Standard Company Benefits. The employment relationship between the parties shall be governed by the general
employment policies and practices of the Company, except that when the terms of this Agreement differ from or are in conflict with the Company’s general employment policies or practices, this Agreement shall control. You shall be entitled to
participate in all employee benefit programs for which you are eligible under the terms and conditions of the benefit plans that may be in effect from time to time and provided by the Company to its employees. The Company reserves the right to
cancel or change the benefit plans or programs it offers to its employees at any time. 
 6.
At-Will Employment. Your employment relationship is at-will. Either you or the Company may terminate the employment relationship at any time, with or without
cause or advance notice. Upon termination of your employment for any reason, you shall resign from all positions and terminate any relationships as an employee, advisor, officer or director with the Company and any of its affiliates, each effective
on the date of termination. 
 7. Outside Activities During Employment. Except with the prior written consent of the Board, you
will not during the term of your employment with the Company undertake or engage in any other employment, occupation or business enterprise, other than ones in which you are a passive investor. You may engage in civic and not-for-profit activities so long as such activities do not materially interfere with the performance of your duties hereunder. You agree not to acquire, assume or participate
in, directly or indirectly, any position, investment or interest known to be adverse or antagonistic to the Company, its business or prospects, financial or otherwise. 

8. Termination; Severance. 

8.1 Term and Termination. The term of this Agreement shall be the period commencing on the Start Date and ending on the date that
this Agreement is terminated by either party pursuant to the provisions of this Agreement. You are employed at-will, meaning that, subject to the terms and conditions set forth herein, either the Company or
you may terminate your employment at any time, with or without Cause.

 8.2 Compensation upon Termination. Upon the termination of your employment for
any reason, the Company shall pay you all of your accrued and unpaid wages earned through your last day of employment (the “Separation Date”). 

8.3 Termination without Cause; Resignation for Good Reason. In the event your employment with the Company is terminated by the
Company without Cause, or you resign for Good Reason, then provided such termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without
regard to any alternative definition thereunder, a “Separation from Service”), and provided that you remain in compliance with the terms of this Agreement (including the conditions described in Section 8.5 below), the Company
shall provide you with the following benefits (the “Severance Benefits”): 
 (a) Cash Severance. The Company
shall pay you, as severance, the equivalent of six (6) months (the “Severance Period”) of your Base Salary in effect as of the Separation Date, subject to standard payroll deductions and withholdings (the
“Severance”). The Severance will be paid as a continuation on the Company’s regular payroll, beginning no later than the first regularly-scheduled payroll date following the sixtieth (60th) day after your Separation from Service, provided the Separation Agreement (as discussed in Section 8.5) has become effective. 

(b) Payment of Continued Group Health Plan Benefits. If you are eligible for and timely elect continued group health plan
coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 or any state law of similar effect (“COBRA”) following your employment termination date, the Company will pay your COBRA group health insurance premiums for
you and your eligible dependents directly to the insurer until the earliest of (A) the end of the period immediately following your employment termination date that is equal to the Severance Period (the “COBRA Payment Period”),
(B) the expiration of your eligibility for continuation coverage under COBRA, or (C) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment. For purposes of
this Section, references to COBRA premiums shall not include any amounts payable by you under a Section 125 health care reimbursement plan under the Code. Notwithstanding the foregoing, if at any time the Company determines, in its sole
discretion, that it cannot pay the COBRA premiums without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then regardless of whether you
elect continued health coverage under COBRA, and in lieu of providing the COBRA premiums, the Company will instead pay you on the last day of each remaining month of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA premiums
for that month, subject to applicable tax withholdings (such amount, the “Special Severance Payment”), which payments shall continue until the earlier of expiration of the COBRA Payment Period or the date when you become eligible
for substantially equivalent health insurance coverage in connection with new employment or self-employment. On the first payroll date following the effectiveness of the Separation Agreement, the Company will make the first payment to the insurer
under this clause (and, in the case of the Special Severance Payment, such payment will be to you, in a lump sum) equal to the aggregate amount of payments that the Company would have paid through such date had such payments instead commenced on the
Separation Date, with the balance of the payments paid thereafter on the schedule described above. If you become eligible for

 Main: (858) 750-4700 Fax: (858) 750-4701 













 
coverage under another employer’s group health plan, you must immediately notify the Company of such event, and all payments and obligations under this subsection shall cease. 

8.4 Termination for Cause; Resignation Without Good Reason; Death or Complete Disability. If the Company terminates your
employment for Cause or you resign without Good Reason, upon dissolution or cessation of the Company, or upon your death or Complete Disability, then (a) you will no longer vest in any equity, (b) all payments of compensation by the
Company to you hereunder will terminate immediately (except as to amounts already earned), and (c) you will not be entitled to any Severance Benefits. 

8.5 Conditions to Receipt of Severance Benefits. The receipt of the Severance Benefits will be subject to you signing and not
revoking a separation agreement and general release of claims in a form reasonably satisfactory to the Company (the “Separation Agreement”) by no later than the sixtieth (60th) day after the Separation Date (“Release
Deadline”). No Severance Benefits will be paid or provided until the Separation Agreement becomes effective. You shall also resign from all positions and terminate any relationships as an employee, advisor, officer or director with the
Company and any of its affiliates, each effective on the Separation Date. 
 9. Definitions. 

9.1 Cause. For purposes of this Agreement, “Cause” for termination means: (a) your repeated failure to
satisfactorily perform your job duties following written notice of such failure by the Board to you and your failure to cure such failure within thirty (30) calendar days following the date you receive such written notice; (b) your
commission of any felony or any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (c) your attempted commission of, or participation in, a fraud or act of dishonesty against the
Company, its affiliates, employees, agents or customers, or your intentional misappropriation for your personal use or benefit of any funds; (d) your engaging, or in any manner participating, in any activity which is directly competitive with
or materially injurious to the Company or which violates any material provisions of Section 10 hereof or the Confidentiality Agreement, or any other unauthorized use or disclosure of the Company’s confidential information or trade secrets;
(e) your intentional, material violation of any contract or agreement between you and the Company or of any statutory duty owed to the Company; or (f) your gross misconduct. The determination that your employment hereunder was terminated
either for Cause or without Cause will be made in good faith by the Company in its sole discretion. Any determination by the Company that your employment was terminated by reason of dismissal without Cause for the purposes of paying your Base Salary
in semimonthly payments at the rate in effect at the time of termination, for a period of six (6) months following your termination, shall have no effect upon any determination of the rights or obligations of the Company or you for any other
purpose. 
 9.2 Code. For purposes of this Agreement, “Code” means the U.S. Internal Revenue Code of 1986 (as
it has been and may be amended from time to time) and any regulations and guidance that has been promulgated or may be promulgated from time to time thereunder and any state law of similar effect. 

9.3 Complete Disability. For purposes of this Agreement, “Complete Disability” shall mean Disability” shall
mean your inability to perform your duties under this 

  
 11099 N Torrey Pines
Road, Suite 290, La Jolla, CA 92037 
 Main: (858) 750-4700 Fax: (858) 750-4701 













 
Agreement, even with reasonable accommodation, because you have become permanently disabled within the meaning of any policy of disability income insurance covering employees of the Company then
in force. In the event the Company has no policy of disability income insurance covering employees of the Company in force when you become disabled, the term “Complete Disability” shall mean your inability to perform your duties
under this Agreement, whether with or without reasonable accommodation, by reason of any incapacity, physical or mental, which the Board, based upon medical advice or an opinion provided by a licensed physician mutually acceptable to the Board and
you (or your legal representative), determines to have incapacitated you from satisfactorily performing all of your usual services for the Company, with or without reasonable accommodation, for a period of at least one hundred eighty
(180) calendar days during any twelve (12) month period (whether or not consecutive). Based upon such medical advice or opinion, the determination of the Board shall be final and binding and the date such determination is made shall be the
date of such Complete Disability for purposes of this Agreement. 
 9.4 Good Reason. For purposes of this Agreement, you shall
have “Good Reason” for resignation from employment with the Company if any of the following actions are taken by the Company without your prior written consent: (a) a material reduction in your Base Salary, which the parties
agree is a reduction of at least 10% of your Base Salary (unless pursuant to a salary reduction program applicable generally to the Company’s similarly situated employees); (b) a material reduction in your duties (including responsibilities
and/or authorities), provided, however, that a change in job position (including a change in title) shall not be deemed a “material reduction” in and of itself unless your new duties are materially reduced from the prior duties; or
(c) relocation of your principal place of employment to a place that increases your one-way commute by more than fifty (50) miles as compared to your then-current principal place of employment
immediately prior to such relocation. In order to resign for Good Reason, you must provide written notice to the Company’s Board within 30 days after the first occurrence of the event giving rise to Good Reason setting forth the basis for your
resignation, allow the Company at least 30 days from receipt of such written notice to cure such event, and if such event is not reasonably cured within such period, you must resign from all positions you then hold with the Company not later than 90
days after the expiration of the cure period. 
 10. Proprietary Information Obligations. As a condition of employment, you
shall execute and abide by the Company’s standard form of Confidential Information and Inventions Assignment Agreement (the “Confidentiality Agreement”), attached as Exhibit A. In your work for the Company, you
will be expected not to use or disclose any confidential information, including trade secrets, of any former employer or other person to whom you have an obligation of confidentiality. Rather, you will be expected to use only that information which
is generally known and used by persons with training and experience comparable to your own, which is common knowledge in the industry or otherwise legally in the public domain, or which is otherwise provided or developed by the Company. You agree
that you will not bring onto Company premises any unpublished documents or property belonging to any former employer or other person to whom you have an obligation of confidentiality. You hereby represent that you have disclosed to the Company any
contract you have signed that may restrict your activities on behalf of the Company. 
 11. Section 409A. It is intended that
all of the severance benefits and other payments payable under this Agreement satisfy, to the greatest extent possible, the exemptions from the 

  
 11099 N Torrey Pines
Road, Suite 290, La Jolla, CA 92037 
 Main: (858) 750-4700 Fax: (858) 750-4701 













 
application of Code Section 409A provided under Treasury Regulations Sections 1.409A 1(b)(4), 1.409A 1(b)(5) and 1.409A 1(b)(9), and this Agreement will be construed to the greatest extent
possible as consistent with those provisions, and to the extent not so exempt, this Agreement (and any definitions hereunder) will be construed in a manner that complies with Section 409A. For all purposes of Code Section 409A (including,
without limitation, for purposes of Treasury Regulations Sections 1.409A 2(b)(2)(i) and (iii)), your right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) shall be treated as a right
to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this Agreement, if you are deemed by the
Company at the time of your Separation from Service to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or under any other agreement
with the Company are deemed to be “deferred compensation,” then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the
related adverse taxation under Section 409A, such payments shall not be provided to you prior to the earliest of (i) the first date following expiration of the six-month period following the date of
your Separation from Service with the Company, (ii) the date of your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of
such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Paragraph shall be paid in a lump sum to you, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement.
No interest shall be due on any amounts so deferred. If the severance benefits are not covered by one or more exemptions from the application of Section 409A and the Release Deadline occurs in the calendar year following the calendar year of
your Separation from Service, the Separation Agreement will not be deemed effective any earlier than the Release Deadline for purposes of determining the timing of provision of any severance benefits. 

12. Arbitration of All Disputes. 

12.1 Agreement to Arbitrate. To ensure the timely and economical resolution of disputes that may arise between you and the Company, both
you and the Company mutually agree that pursuant to the Federal Arbitration Act, 9 U.S.C. §1-16, and to the fullest extent permitted by applicable law, you and the Company will submit solely to final,
binding and confidential arbitration any and all disputes, claims, or causes of action arising from or relating to: (i) the negotiation, execution, interpretation, performance, breach or enforcement of this Agreement; or (ii) your
employment with the Company (including but not limited to all statutory claims); or (iii) the termination of your employment with the Company (including but not limited to all statutory claims). BY AGREEING TO THIS ARBITRATION PROCEDURE,
BOTH YOU AND THE COMPANY WAIVE THE RIGHT TO RESOLVE ANY SUCH DISPUTES THROUGH A TRIAL BY JURY OR JUDGE OR THROUGH AN ADMINISTRATIVE PROCEEDING. 

12.2 Arbitrator Authority. The arbitrator shall have the sole and exclusive authority to determine whether a dispute, claim or
cause of action is subject to arbitration under this Section and to determine any procedural questions which grow out of such disputes, claims or causes of action and bear on their final disposition.

Road, Suite 290, La Jolla, CA 92037 
 Main: (858) 750-4700 Fax: (858) 750-4701 













 12.3 Individual Capacity Only. All claims, disputes, or causes of action under
this Section, whether by you or the Company, must be brought solely in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any purported class or representative proceeding, nor joined or consolidated with
the claims of any other person or entity. The arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative or class proceeding. To the extent that the preceding sentences in this
Section are found to violate applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court of law rather than by arbitration. 

12.4 Arbitration Process. Any arbitration proceeding under this Section shall be presided over by a single arbitrator and
conducted by Judicial Arbitration and Mediation Services, Inc. (“JAMS”) in San Diego, California, or as otherwise agreed to by you and the Company, under the then applicable JAMS rules for the resolution of employment disputes
(available upon request and also currently available at http://www.jamsadr.com/rules-employment-arbitration/). You and the Company both have the right to be represented by legal counsel at any arbitration proceeding, at each party’s own
expense. The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute; (ii) issue a written arbitration decision, to include the arbitrator’s essential
findings and conclusions and a statement of the award; and (iii) be authorized to award any or all remedies that you or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS arbitration fees in
excess of the amount of court fees that would be required of you if the dispute were decided in a court of law. 
 12.5 Excluded
Claims. This Section shall not apply to any action or claim that cannot be subject to mandatory arbitration as a matter of law, including, without limitation, claims brought pursuant to the California Private Attorneys General Act of 2004, as
amended, the California Fair Employment and Housing Act, as amended, and the California Labor Code, as amended, to the extent such claims are not permitted by applicable law to be submitted to mandatory arbitration and such applicable law is not
preempted by the Federal Arbitration Act or otherwise invalid (collectively, the “Excluded Claims”). In the event you intend to bring multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be
filed with a court, while any other claims will remain subject to mandatory arbitration. 
 12.6 Injunctive Relief and Final
Orders. Nothing in this Section is intended to prevent either you or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any final award in any arbitration proceeding
hereunder may be entered as a judgment in the federal and state courts of any competent jurisdiction and enforced accordingly. 
 13.
General Provisions. This Agreement, together with the Confidentiality Agreement, constitutes the entire agreement between you and the Company with regard to this subject matter and is the complete, final, and exclusive embodiment of the
parties’ agreement with regard to this subject matter. This Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other such promises,
warranties or representations, including without limitation that certain Employment Agreement between you and Arafix, Inc. dated September 1, 2009 (the “Prior 

  
 11099 N Torrey Pines
Road, Suite 290, La Jolla, CA 92037 
 Main: (858) 750-4700 Fax: (858) 750-4701 













 
Agreement”). You agree and acknowledge that there are no circumstances as of the date of this Agreement that constitute, and nothing contemplated in this Agreement shall be deemed for
any purpose to be or to create, an involuntary termination without Cause, including for purposes of the Prior Agreement, or any other severance or change in control plan, agreement or policy maintained by the Company. You further hereby expressly
waive any claim or right you may have as of the date of this Agreement (if any) to assert that this Agreement, or any other condition or occurrence, forms the basis for a without Cause termination for any purpose, including for purposes of the Prior
Agreement, or any other severance or change in control plan, agreement or policy maintained by the Company. Modifications or amendments to this Agreement, other than those changes expressly reserved to the Company’s discretion in this letter,
must be made in a written agreement signed by you and the Company’s Board. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this
Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this
Agreement will be reformed, construed and enforced in such jurisdiction to the extent possible in keeping with the intent of the parties. Any waiver of any breach of any provisions of this Agreement must be in writing to be effective, and it shall
not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement. This Agreement is intended to bind and inure to the benefit of and be enforceable by you and the Company, and their
respective successors, assigns, heirs, executors and administrators. The Company may freely assign this Agreement, without your prior written consent. You may not assign any of your duties hereunder and you may not assign any of your rights
hereunder without the written consent of the Company. This Agreement shall become effective as of the Start Date and shall terminate upon your termination of employment with the Company. The obligations as forth under Sections 8, 9, 10, 11, 12, and
13 will survive the termination of this Agreement. All questions concerning the construction, validity and interpretation of this Agreement will be governed by the laws of the State of California. 

This offer is subject to satisfactory proof of your identity and right to work in the United States and other applicable pre-employment screenings. 
 We look forward to having you join us. If you have any questions about this
Agreement, please do not hesitate to call me.
