ARYD ARYA Sciences Acquisition Corporation IV

On November 7, 2022, ARYA Sciences Acquisition Corp IV (the “Company”) issued an unsecured convertible promissory note (the “Convertible Promissory Note”) to ARYA Sciences Holdings IV (the “Sponsor”), pursuant to which the Company may borrow $120,000 (the “Working Capital Loan”) from the Sponsor for general corporate purposes. Such loan may, at the Sponsor’s discretion, be converted into Class A ordinary shares, par value $0.0001 per share, of the Company (the “Working Capital Shares”) at a conversion price equal to $10.00 per Working Capital Share. The terms of the Working Capital Shares will be identical to those of the private placement shares that were issued to the Sponsor in connection with the Company’s initial public offering that was consummated on March 2, 2021  (the “Private Placement Shares”). The Working Capital Loan will not bear any interest, and will be repayable by the Company to the Sponsor, if not converted or repaid on the effective date of an initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Company and one or more businesses. The maturity date of the Working Capital Loan may be accelerated upon the occurrence of an Event of Default (as defined under the Convertible Promissory Note). The Company granted customary registration rights to the Sponsor with respect to any Working Capital Shares, which shall constitute “Registrable Securities” pursuant to that certain Registration and Shareholder Rights Agreement, dated March 2, 2021, by and among the Company, the Sponsor and the other parties thereto. Further, each newly issued Working Capital Share shall bear the same transfer restrictions that apply to the Private Placement Shares, as contemplated by the Letter Agreement, dated February 25, 2021, by and among the Company, the Sponsor and the other parties thereto.

The foregoing description of the Convertible Promissory Note does not purport to be complete and is qualified in its entirety by the terms and conditions of thereof. A copy of the Convertible Promissory Note is attached hereto as Exhibit 10.1 and incorporated herein by reference.
