 BOLT BIOTHERAPEUTICS, INC. 

AT-WILL EMPLOYMENT, CONFIDENTIAL INFORMATION, INVENTION ASSIGNMENT, 

AND ARBITRATION AGREEMENT 

As a condition of my employment with Bolt Biotherapeutics, Inc. (the “Company”), and in consideration of my employment with
the Company and my receipt of the compensation now and hereafter paid to me by Company, I agree to the following provisions of this At-Will Employment, Confidential Information, Invention Assignment, and
Arbitration Agreement (this “Agreement”): 
  

	 	1.	 AT-WILL
EMPLOYMENT 


 I UNDERSTAND AND ACKNOWLEDGE THAT MY EMPLOYMENT WITH THE COMPANY IS FOR
NO SPECIFIED TERM AND CONSTITUTES “AT-WILL” EMPLOYMENT. I ALSO UNDERSTAND THAT ANY REPRESENTATION TO THE CONTRARY IS UNAUTHORIZED AND NOT VALID UNLESS IN WRITING AND SIGNED BY THE PRESIDENT OR
CEO OF THE COMPANY. ACCORDINGLY, I ACKNOWLEDGE THAT MY EMPLOYMENT RELATIONSHIP MAY BE TERMINATED AT ANY TIME, WITH OR WITHOUT GOOD CAUSE OR FOR ANY OR NO CAUSE, AT MY OPTION OR AT THE OPTION OF THE COMPANY, WITH OR WITHOUT NOTICE. I FURTHER
ACKNOWLEDGE THAT THE COMPANY MAY MODIFY JOB TITLES, SALARIES, AND BENEFITS FROM TIME TO TIME AS IT DEEMS NECESSARY. 
  

	 	2.	 CONFIDENTIALITY 



A.    Definition of Company Confidential Information. I understand that “Company Confidential
Information” means information (including any and all combinations of individual items of information ) that the Company has or will develop, acquire, create, compile, discover or own, that has value in or to the Company’s business
which is not generally known and which the Company wishes to maintain as confidential. Company Confidential Information includes both information disclosed by the Company to me, and information developed or learned by me during the course of my
employment with the Company. Company Confidential Information also includes all information of which the unauthorized disclosure could be detrimental to the interests of the Company, whether or not such information is identified as Company
Confidential Information. By example, and without limitation, Company Confidential Information includes any and all non-public information that relates to the actual or anticipated business and/or products,
research or development of the Company, or to the Company’s technical data, trade secrets, or know-how, including, but not limited to, research, product plans, or other information regarding the
Company’s products or services and markets therefor, customer lists and customers (including, but not limited to, customers of the Company on which I called or with which I may become acquainted during the term of my employment), software,
developments, inventions, discoveries, ideas, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances, and other business information disclosed by the Company either directly or
indirectly in writing, orally or by drawings or inspection of premises, parts, equipment, or other Company property. Notwithstanding the foregoing, Company Confidential Information shall not include any such information which I can establish
(i) was publicly known or made generally available prior to the time of disclosure by the Company to me; (ii) becomes publicly known or made generally available after disclosure by the Company to me through no wrongful action or omission
by me; or (iii) is in my rightful possession, without confidentiality obligations, at the time of disclosure by the Company as shown by my then-contemporaneous written records; provided that any combination of individual items of information
shall not be deemed to be within any of the foregoing exceptions merely because one or more of the individual items are within such exception, unless the combination as a whole is within such exception. I understand that nothing in this Agreement is
intended to limit employees’ rights to discuss the terms, wages, and working conditions of their employment, as protected by applicable law. 













 B.    Nonuse and Nondisclosure. I agree that during and after my
employment with the Company, I will hold in the strictest confidence and take all reasonable precautions to prevent any unauthorized use or disclosure of Company Confidential Information. I will not (i) use Company Confidential Information for
any purpose whatsoever other than for the benefit of the Company in the course of my employment, or (ii) disclose Company Confidential Information to any third party without the prior written authorization of the President, CEO, or the Board of
Directors of the Company. Prior to disclosure, when compelled by applicable law, I shall provide prior written notice to the President, CEO, and General Counsel of the Company (as applicable). I agree that I obtain no title to any Company
Confidential Information, and that as between Company and myself, the Company retains all Confidential Information as the sole property of the Company. I understand that my unauthorized use or disclosure of Company Confidential Information during my
employment may lead to disciplinary action, up to and including, immediate termination and legal action by the Company. I understand that my obligations under this Section 2.B shall continue after termination of my
employment and also that nothing in this Agreement prevents me from engaging in Protected Activity, as described below. 

C.    Former Employer Confidential Information. I agree that during my employment with the Company, I will not
improperly use, disclose, or induce the Company to use any proprietary information or trade secrets of any former employer or other person or entity with which I have an obligation to keep such proprietary information or trade secrets in confidence.
I further agree that I will not bring onto the Company’ s premises or transfer onto the Company’s technology syst ems any unpublished document, proprietary information, or trade secrets belonging to any such third party unless disclosure
to, and use by, the Company has been consented to, in writing, by such third party and the Company. 
 D.    Third
Party Information. I recognize that the Company has received, and in the future may receive, from third parties (for example, customers, suppliers, licensors, licensees, partners, and collaborators) as well as its subsidiaries and affiliates
(“Associated Third Parties”), information which the Company is required to maintain and treat as confidential or proprietary information of such Associated Third Parties (“Associated Third Party Confidential
Information”), and I agree to use such Associated Third Party Confidential Information only as directed by the Company and to not use or disclose such Associated Third Party Confidential Information in a manner that would violate the
Company’s obligations to such Associated Third Parties. By way of example, Associated Third Party Confidential Information may include the habits or practices of Associated Third Parties, the technology of Associated Third Parties, requirements
of Associated Third Parties, and information related to the business conducted between the Company and such Associated Third Parties. I agree at all times during my employment with the Company and thereafter, that I owe the Company and its
Associated Third Parties a duty to hold all such Associated Third Party Confidential Information in the strictest confidence, and not to use it or to disclose it to any person, firm, corporation, or other third party except as necessary in carrying
out my work for the Company consistent with the Company’s agreement with such Associated Third Parties. I further agree to comply with any and all Company policies and guidelines that may be adopted from time to time regarding Associated Third
Parties and Associated Third Party Confidential Information. I understand that my unauthorized use or disclosure of Associated Third Party Confidential Information or violation of any Company policies during my employment may lead to disciplinary
action, up to and including, immediate termination and legal action by the Company.

protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act. I understand and agree that the decision whether or not to commercialize or market any Inventions is within the
Company’s sole discretion and for the Company’ s sole benefit, and that no royalty or other consideration will be due to me as a result of the Company’ s efforts to commercialize or market any such Inventions. 

B.    Pre-Existing Materials. I will inform the Company, in writing, before
incorporating any inventions, discoveries, ideas, original works of authorship, developments, improvements, trade secrets and other proprietary information or intellectual property rights owned by me or in which I have an interest prior to, or

restriction, including, without limitation, as part of, or in connection with, such Invention, and to practice any method related thereto. I will not incorporate any inventions, discoveries, ideas, original works of authorship, developments,
improvements, trade secrets and other proprietary information or intellectual property rights owned by any third party into any Invention without the Company’s prior written permission. I have attached hereto as Exhibit A a list
describing all Prior Inventions that relate to the Company’s proposed business, products, or research and development or, if no such list is attached, I represent and warrant that there are no such Prior Inventions. Furthermore, I represent and
warrant that if any Prior Inventions are included on Exhibit A, they will not materially affect my ability to perform all obligations under this Agreement. 

C.    Moral Rights. Any assignment to the Company of Inventions includes all rights of attribution, paternity,
integrity, modification, disclosure and withdrawal, and any other rights throughout the world that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like (collectively,
“Moral Rights”). To the extent that Moral Rights cannot be assigned under applicable law, I hereby waive and agree not to enforce any and all Moral Rights, including, without limitation, any limitation on subsequent modification, to
the extent permitted under applicable law.

proceeding relating to such Inventions. I further agree that my obligations under this Section 3.E shall continue after the termination of this Agreement. 

F.    Attorney-in-Fact. l agree
that, if the Company is unable because of my unavailability, mental or physical incapacity, or for any other reason to secure my signature with respect to any Inventions, including, without limitation, for the purpose of applying for or pursuing any
application for any United States or foreign patents or mask work or copyright registrations covering the Inventio ns assigned to the Company in Section 3.A, then I hereby irrevocably designate and appoint the Company and
its duly authorized officers and agents as my agent and attorney-in-fact, to act for and on my behalf to execute and file any papers and oaths, and to do all other
lawfully permitted acts with respect to such Inventions to further the prosecution and issuance of patents, copyright and mask work registrations with the same legal force and effect as if executed by me. This power of attorney shall be deemed
coupled with an interest, and shall be irrevocable.

 EXHIBIT D 

BOLT BIOTHERAPEUTICS, INC. CONFLICT OF INTEREST GUIDELINES 

It is the policy of Bolt Biotherapeutics, Inc. to conduct its affairs in strict compliance with the letter and spirit of the law and to adhere
to the highest principles of business ethics. Accordingly, all officers, employees, and independent contractors must avoid activities that are in conflict, or give the appearance of being in conflict, with these principles and with the interests of
the Company. The following are potentially compromising situations that must be avoided: 
 1.    Revealing confidential
information to outsiders or misusing confidential information. Unauthorized divulging of information is a violation of this policy whether or not for personal gain and whether or not harm to the Company is intended. (The At-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement elaborates on this principle and is a binding agreement.) 

2.    Accepting or offering substantial gifts, excessive entertainment, favors, or payments that may be deemed to
constitute undue influence or otherwise be improper or embarrassing to the Company. 
 3.    Participating in civic or
professional organizations that might involve divulging confidential information of the Company. 
 4.    Initiating or
approving personnel action s affecting reward or punishment of employees or applicants where there is a family relationship or is, or appears to be, a personal or social involvement. 

5.    Initiating or approving any form of personal or social harassment of employees. 

6.    Investing or holding outside directorship in suppliers, customers, or competing companies, including financial
speculations, where such investment or directorship might influence in any manner a decision or course of action of the Company. 

7.    Borrowing from or lending to employees, customers, or suppliers. 

8.    Acquiring real estate of interest to the Company. 

9.    Improperly using or disclosing to the Company any proprietary information or trade secrets of any other employer or
other person or entity with whom obligations of confidentiality exist. 
 10.    Unlawfully discussing prices, costs,
customers, sales, or markets with competing companies or their employees. 
 11.    Making any unlawful agreement with
distributors with respect to prices. 
 12.    Improperly using or authorizing the use of any inventions that are the
subject of patent claims of any other person or entity. 
 13.    Engaging in any conduct that is not in the best
interest of the Company. 
 Each officer, employee, and independent contractor must take every necessary action to ensure compliance with
these guidelines and to bring problem areas to the attention of higher management for review. Violations of this conflict of interest policy may result in discharge without warning. 













 Nothing in these guidelines is intended to limit employees’ rights to discuss the
terms, wages, and working conditions of their employment, as protected by applicable law. Also, nothing in these guidelines is intended to limit or prohibit employees from engaging in any Protected Activity. “Protected Activity” means
filing a charge or complaint or complaint with, or otherwise communicating or cooperating with or participating in any investigation or proceeding that may be conducted by any federal, state or local government agency or commission, including the
Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”). In connection with such Protected Activity,
employees are permitted to disclose documents or other information as permitted by law, and without giving notice to, or receiving authorization from, the Company. Notwithstanding, in making any such disclosures or communications, employees must
take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company Confidential Information to any parties other than the Government Agencies. “Protected Activity” does not include
the disclosure of any Company attorney-client privileged communications.
