permissible date of distribution under Section 409A(a)(2)(A) of the Code and the regulations thereunder, and where Section 409A of the Code applies to such distribution, the Beneficiary shall definitively acquire the Free Shares on the date

|
| b) |
the Executive Board may, at its sole discretion but with the prior approval of the Supervisory Board, at any time during the Holding Period, decide to waive for a concerned Beneficiary the Holding Period in respect of a sufficient number

under no circumstances shall this waiver result in an Acquisition Period and, where applicable, a Holding Period of less than 2 years.

| (1) | The amount of shares registered may be represented by American Depositary Shares, or ADSs, of Nanobiotix S.A. (the “Registrant”). Each ADS represents one ordinary share of the Registrant. The Registrant’s ADSs issuable upon deposit of the ordinary shares registered hereby have been registered pursuant to a separate registration statement on Form F-6 (File No. 333-250880). Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement shall also cover any additional ordinary shares of the Registrant that may become issuable under the Registrant’s 2026 Free Share Plan by reason of any share dividend, share split, share combination, recapitalization or other similar transaction effected without receipt of consideration that increases the number of the Registrant’s outstanding ordinary shares. The Proposed Maximum Offering Price Per Unit is estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and Rule 457(h) of the Securities Act based upon the price of $35.31 per ADS, which was the average of the high and low prices of the ADS as reported on NASDAQ for June 3, 2026 (rounded to the nearest cent). |
