 Exhibit 10.13 

EXCHANGE AGREEMENT 

THIS EXCHANGE AGREEMENT (this “Agreement”) is made as of April
[●], 2021, by and among the investors listed on Exhibit A attached hereto (each an “Investor” and together, the “Investors”) and Rain Therapeutics Inc., a Delaware corporation
(the “Company”). 
 RECITALS 

A. Each Investor holds that number of shares of the Company’s Series A Preferred Stock, par value $0.001 per share
(“Series A Preferred”) and the Company’s Series B Preferred Stock, par value $0.001 per share (“Series B Preferred”), set forth opposite such Investor’s name on Exhibit
A attached hereto (the “Preferred Exchange Stock”). 
 B. Subject to the terms and
conditions and limitations set forth herein, each Investor desires to exchange up to the number of shares of Preferred Exchange Stock set forth opposite such Investor’s name on Exhibit A attached hereto for shares of a
newly designated Non-Voting Common Stock of the Company, par value $0.001 per share (the
“Non-Voting Common”). 
 NOW
THEREFORE, in consideration of the foregoing premises and the respective representations and warranties, covenants and agreements contained herein, the receipt and sufficiency of which is hereby acknowledged, the Company and each of the
Investors agree as follows: 
 Article I: Exchange 

1.1 Upon the terms and subject to the conditions herein contained, at the Closing (as defined below), the Applicable Number of Shares (defined
below) of Preferred Exchange Stock held by each investor shall, automatically, and without any further action on the part of the Investors or the Company, be exchanged for shares of Non-Voting Common
at a ratio of [●] shares of Non-Voting Common for every single share of Preferred Exchange Stock (rounded down to the nearest whole share). Each Investor shall assign and deliver to the Company
Preferred Exchange Stock (including any stock certificates representing the Applicable Number of Shares) for cancellation by the Company, free and clear of any mortgage, lien, pledge, charge, security interest, encumbrance, title retention
agreement, option, equity or other adverse claim thereto (collectively, “Liens”), other than restrictions on transfer under applicable securities laws, together with any documents of conveyance or transfer that the Company
may deem reasonably necessary or desirable, and in exchange therefor the Company shall issue to each Investor [●] shares of Non-Voting Common (rounded down to the nearest whole share) for each
single share of Preferred Exchange Stock exchanged hereunder. The “Applicable Number of Shares” shall mean, for each Investor, such number of shares of Preferred Exchange Stock (which may be zero) as would be necessary to
cause such Investor, immediately following the closing of the IPO, to beneficially own (for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended and the rules and regulations promulgated thereunder (collectively, the
“Exchange Act”)), when aggregated with such Investor’s affiliates who are also party hereto, not more than 9.99% (or such other amount as may be agreed to by the Company and the applicable Investor) of the Company’s
Voting Common Stock. The exchange of the Preferred Exchange Stock for the Non-Voting Common pursuant to this Agreement is referred to herein as the “Exchange.” 

1.2 Each Investor severally, and not jointly, shall be liable for only the Exchange that relates to such Investor. The Company’s agreement
with each of the Investors is a separate agreement, and the Exchange with respect to each Investor is a separate exchange. The obligations of each Investor hereunder are expressly not conditioned on the exchange of
the Non-Voting Stock by any or all of the other Investors. 
 1.3 Subject to the
satisfaction of each of the conditions set forth in Article IV and Article V hereof (to the extent not waived in accordance therewith), the closing of the Exchange (the “Closing”) shall take place remotely immediately
prior to the closing of a firm-commitment underwritten public offering of the Company’s Voting Common Stock pursuant to the Company’s Registration Statement on Form S-1 (file number 333-254998) (the “IPO”) (the date on which such Closing occurs is hereinafter referred to as the “Closing Date”).

instrument in writing signed on behalf of each of the parties to this Agreement. 
 6.3. Termination. This Agreement shall

6.4. Governing Law. This Agreement shall in all respects be construed in accordance with and governed by the substantive laws of
the State of Delaware, without reference to its choice of law rules. 
 6.5. Severability. Any term or provision of
this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or

Transactions. Gibson Dunn has served as outside general counsel to the Company and has negotiated the terms of the Transactions solely on behalf of the Company. The Company and each Investor hereby (a) acknowledge that they have had an
opportunity to ask for and have obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of such representation; (b) acknowledge that with respect to the negotiation,
preparation, execution and performance of this Agreement and the consummation of the Transactions, Gibson Dunn has represented solely the Company, and not any Investor or any stockholder, member, beneficiary, director or employee of any Investor;

6.7. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Counterparts may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission
