Erytech Pharma S.A. 
 Bâtiment Adénine 

60 Avenue Rockefeller 
 69008 Lyon 

France 
 The undersigned (the “Investor”) hereby
confirms its agreement with you as follows: 
  

	1.	 This Subscription Agreement (the “Agreement”) is made as of the date set forth below between
Erytech Pharma S.A., a societé anonyme organized under the laws of France, with a share capital of €2,164,648.90 and a registered office at Bâtiment Adénine, 60 Avenue Rockefeller, 69008 Lyon France, registered with
the Register of Commerce and Companies (Registre du commerce et des sociétés) of Lyon under the number 479 560 013 (the “Company”), and the Investor. 



 

	2.	 The Investor wishes to purchase and the Company wishes to issue, upon the terms and conditions stated in this
Agreement (the “Offering”), without preferential subscription rights to specified categories of investors up to 1,034,483 shares with warrants attached (Actions à bons de souscription d’actions or ABSA)
(the “Units”), each consisting of (i) four ordinary shares, par value €0.10 per share (each, a “Share”) and (ii) three warrants, each warrant to purchase one Share (each, a
“Warrant”), whose Terms and Conditions (the “Terms and Conditions of the Warrants”) are attached hereto as Exhibit A (as exercised, collectively the “Warrant Shares”), for a subscription
price of $29.00 per Unit (the “Subscription Price”), pursuant to the 25th resolution of the combined general meeting of the shareholders of the Company held on June 26, 2020
(the “25th Resolution”). The issuance of the Shares will result in an immediate capital increase of €24,868,971.30 (divided into a nominal amount of
€413,793.20 and a total issuance premium of €24,455,178.10 and corresponding to a nominal value of ten cents (€0.10) plus an issuance premium of €5.91 per Share issued). Immediately upon creation, each Share within a Unit will be
transferred to The Bank of New York Mellon (the “Depositary”) and the Depositary will issue one American Depositary Share (“ADS”) instead of such Share to the Investor purchasing such Unit. 



 

	3.	 The Shares, including as represented by the ADSs, the Warrants and the Warrant Shares collectively are referred
to herein as the “Securities.” 


  

	4.	 The Securities will be issued pursuant to an effective registration statement under the U.S. Securities Act of
1933, as amended (the “Securities Act”). 


  

	5.	 In connection with the offering and sale of the Securities, the Company has entered into a placement agent
agreement dated April 29, 2021 (the “Placement Agent Agreement”) with H.C. Wainwright & Co., LLC (the “Placement Agent”). 


  


	6.	 The Company and the Investor agree that the Investor will subscribe from the Company and the Company will issue
to the Investor, who meets the categories defined in the 25th Resolution, namely (i) natural and legal persons, including companies, trusts or investment funds, organized under French or
foreign law, that regularly invest in the pharmaceutical, biotechnological or medical technology sector and/or (ii) companies, institutions or entities of any type, French or foreign, that exercise a significant part of their business in the
pharmaceutical, cosmetic, chemical or medical devices and/or technologies or research in these sectors, the number of Units set forth below for the aggregate subscription price set forth below. The Units shall be subscribed for pursuant to, and the
manner of settlement shall be as set forth in, the Terms and Conditions for Subscription of Units attached hereto as Annex I and incorporated herein by this reference as if fully set forth herein. The Investor expressly acknowledges and
agrees that all representations, warranties, covenants and agreements made or given by the Investor to the Company herein, and specifically as made or given in the Terms and Conditions for Subscription of Units attached hereto as Annex I, are
also irrevocably made and given for the benefit of the Placement Agent (as defined in Annex I hereto) and that the Placement Agent is entitled to rely on the same in connection with the placement of the Units. 















	7.	 The Company and the Investor agree that the Investor may, on an annual basis, request information related to
the Company’s status for United States federal income tax purposes as a “passive foreign investment company” and information required for IRS form 5471 status and the Company will use its commercially reasonable efforts to provide any
information the Company has in its possession or can obtain without significant burden that the Investor is required to have under United States tax law for such purpose. 



 

	8.	 The Investor represents and warrants that, except as set forth below, it has had no position, office or other
material relationship (including, but not limited to, a commercial, industrial, banking, consulting or accounting relationship) within the past three years with the Company or any of its affiliates.

in any jurisdiction where action for that purpose is required. 


  

	4.6	 The Investor further represents and warrants to, and covenants with, the Company that (a) the Investor has
full right, power, authority and capacity to enter into this Agreement (including the Terms and Conditions of the Warrants) and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution,
delivery and performance of this Agreement (including the Terms and Conditions of the Warrants), and (b) this Agreement and the Terms and Conditions of the Warrants constitute a valid and binding obligation of the Investor enforceable against

	4.7	 All of the Investor’s information on the Signature Page hereto may be used in connection with the
admission to trading of the Shares on Euronext Paris and the information thereon is true and correct as of the date hereof and will be true and correct as of the Closing Date.

Majesty’s Treasury.
