the "Loans") in the aggregate amount of up to USD 1'530'000.00 (the "Principal Amount").

Lender grants a Loan with an amount as further specified in Annex A beside such Lenders' name.

rights of each Lender under or in connection with the Agreement are separate and independent rights and any debt arising under the Agreement

obligation entered into by the Lenders under this Agreement shall be construed as a joint and several liability of the Lenders and the

Lenders explicitly waive any joint and several liability (Ausschluss der Solidarhaftung). Each Lender shall only be liable to

contribute to the payment of its Loan in proportion as set forth in Section 2 above. No Lender will be liable for any obligation of another

Lender. Each Lender shall accordingly be solely and independently responsible for its own obligations under this Agreement.

coupon shall apply on the Principal Amount at a coupon rate of 10% per annum and be calculated on the basis of the actual number of days

elapsed and assuming a 365-day year, from and including the relevant value date of the Loan.

whichever occurs earlier.

above on the cover page (i.e., November 17, 2022) (the "Maturity Date").

number of Conversion Shares issuable upon such Conversion shall be determined by di-viding the Loan Balance of each respective Lender

by the applicable Conversion Price.

Lender has the right to exercise its conversion right at any time other than the events specified in this Section 8.1.

Lender hereby undertakes to take all such actions as may be reasonably necessary or appropriate in order to implement the Conversion,

relevant Loan Balance.

Borrower shall accept each respective Lender as new shareholder of the Borrower with voting rights and will not claim any restriction

on transferability of shares on the grounds of the articles of association of the Borrower (Statuten) or for any other reasons.

The Borrower undertakes to disclose to each Lender all information necessary to ensure that such Lender can ascertain in due course the

proper calculation of the Conversion Price. To the extent required for the implementation of the Conversion, the Borrower shall use best

efforts to procure that the shareholders of the Borrower waive their subscription rights in order to allow for the respective Lender

to become a shareholder of the Borrower according to the terms of this Agreement.

increase may not be authorized by the Borrower at that given time. However, the Borrower will take all reasonable measures in order to

take such corporate actions and obtain all authorizations and consents necessary to authorize and issue such shares to ensure that the

respective Lender can enforce their conversion right under this Agreement.

this Agreement between the respective Lender and the Borrower shall be deemed to have been mutually settled, except for the claims in

connection with the Warrant Coverage set forth in Section 10.

Shares, the Conversion Price and/or other terms of the Conversion shall be adjusted so that the number of Conversion Shares will reflect

such effects without detriment to each Lender.

Loan shall not be secured.

Borrower will grant on the date first written above to each Lender the right to purchase shares of the Borrower in form of options (such
