THIS NOMINATING AGREEMENT (this “Agreement”), dated as of June 28, 2019, is by and between IGM Biosciences, Inc., a
Delaware corporation (the “Company”) Redmile Biopharma Investments II, L.P., RAF, L.P. and Redmile Strategic Master Fund, LP (each an “Investor” and together, the “Investors”). 

WHEREAS, the Company and the Investors are parties to that certain Series C Preferred Stock Purchase Agreement dated of even date herewith
(the “Purchase Agreement”) pursuant to which the Investors are purchasing shares of Series C Preferred Stock (“Series C Shares”); 

WHEREAS, in order to induce the Investors to invest funds in the Company pursuant to the Purchase Agreement, the Investors and the Company
hereby agree that this Agreement shall set forth certain rights and obligations with respect to the shares of the Company’s capital stock beneficially owned by the Investors. 

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto, intending
to be legally bound, hereby agree as follows: 
 1. Definitions. As used in this Agreement, the following terms shall have the
following respective meanings: 
 (a) “Affiliate” has the meaning given to that term in Rule 12b-2 under the Securities Exchange Act of 1934, as amended. 
 (b) “Board of
Directors” means the Board of Directors of the Company. 
 (c) “Bylaws” means the Bylaws of the Company, as
may be amended, restated or otherwise modified from time to time. 
 (d) “Common Stock” means shares of the
Company’s Common Stock, par value $0.01 per share. 
 (e) “IPO” means the Company’s first underwritten
public offering of its Common Stock under the Securities Act of 1933, as amended. 
 2. Board Representation. 

(a) Subject at all times to Sections 2(b) and 3(n) herein, during the period beginning at the closing of the IPO until the earliest of
(a) the twelfth anniversary of the date of the closing of the IPO; (b) such time as the Investors and their respective Affiliates no longer beneficially own, collectively, at least 6,250,000 Series C Shares or the equivalent of any
successor securities issued upon conversion of such Series C Shares (including shares of voting common stock issued upon conversion of non-voting common stock issued upon conversion of the Series C Shares) (as
adjusted for any stock dividends, combinations, splits, recapitalizations and the like with respect to such Series C Shares), or (c) following the third year anniversary of the IPO, such time as the Investors collectively hold less than 5% of
the as-converted securities of the Company, the Company shall support the nomination of, and cause the Board of Directors (or the nominating committee thereof), subject to the requirements of fiduciary duties
under applicable law, to recommend and include in the slate of nominees recommended to the Company’s stockholders for election as directors of the Company at each annual or special meeting of the Company’s stockholders at which directors
are to be 













 
elected (an “Election Meeting”), one (1) person designated at any time and from time to time by the mutual consent of the Investors (an “Investor
Designee”); provided that, the Company shall have no obligation to support the nomination of or cause the Board of Directors to include in the slate of nominees recommended to the Company’s stockholders for election as directors of the
Company an Investor Designee if the Investors already have an Investor Designee serving as a director on the Board of Directors at the time of the Election Meeting and the term(s) of such Investor Designee(s) as a director on the Board of Directors
does not expire at such Election Meeting. In the event that an Investor Designee resigns from his or her seat on the Board of Directors or is removed or otherwise fails to become or ceases to be a director for any reason, the vacancy will be filled
by the election or appointment of another Investor Designee nominated by the Investors as soon as reasonably practicable in compliance with applicable laws, rules and regulations. The Investors will provide the Company, in writing, the information
about any Investor Designee that is reasonably required by applicable law promptly after the Company requests such information from the Investors, and will cause any Investor Designee to submit on a timely basis to the Company a completed and
executed questionnaire in the form that the Company provides to its outside directors generally. 
 (b) Notwithstanding the provisions
of Section 2(a), the Investors shall not be entitled to designate any person as a nominee to the Board of Directors if (i) a majority of the disinterested members of the Board of Directors reasonably and in good faith determines, after
consultation with the Company’s outside legal counsel, that such person would not be qualified to serve as a director of the Company under any applicable law (including requirements of fiduciary duties under applicable law), rule or regulation,
rule of the stock exchange on which the Company’s shares are listed, the Bylaws or any policy, or guidelines previously approved by the Board of Directors or (ii) such person is not approved for nomination by the Board of Directors (or the
nominating committee thereof). The Company shall notify the Investors as soon as reasonably practicable of any objection to an Investor Designee pursuant to this Section 2(b) as to enable the Investors to propose a replacement Investor Designee
in accordance with the terms of this Agreement. The Investors shall use reasonable best efforts to propose an Investor Designee sufficiently in advance of the date on which the proxy materials are to be mailed by the Company in connection with an
Election Meeting to allow for inclusion of an Investor Designee in such proxy materials. 
 3. Miscellaneous.

Delaware, without giving effect to its principles of conflicts of laws.

sale of assets or otherwise) that may be issued in respect of, in exchange for, or in substitution for the shares of Common Stock, by combination, recapitalization, reclassification, merger, consolidation or otherwise and the term “Common
Stock” shall include all such other securities. In the event of any change in the capitalization of the Company, as a result of any stock split, stock dividend or stock combination or otherwise, the provisions of this Agreement shall be
appropriately adjusted.
