Preamble

A. The Company is a German limited liability company (Gesellschaft mit beschränkter Haftung), with its business address at ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, registered with the commercial register of the local court (Amtsgericht) of Munich under HRB 224131.

D. ▇▇▇▇▇ ▇▇▇▇▇, the sole shareholder of Purchaser 1, and ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇▇, the sole shareholder of Purchaser 2, are currently the managing directors of the Company.

E. The Company has a registered share capital of EUR 33,588.00 (in words: thirty-three thousand five hundred and eighty-eight euros), divided into 33,588 (in words: thirty-three thousand five hundred and eighty-eight) shares with the consecutive numbers 1 to 33,588 held by the Seller (the "Shares").

F. The Seller has granted several unsecured, interest-bearing shareholder loans in the total nominal amount of EUR 9,806,000.00 (in words: nine million eight hundred and six thousand euros) to the Company (the "Shareholder Loans") in connection with a so-called back to back letter of credit dated 18 November 2023 (the "LoC") between the Seller and the Company. As of 29 April 2026, a total amount of EUR 10,507,498.01 (in words: ten million five hundred and seven thousand four hundred and ninety-eight euros and one cent), is outstanding under the Shareholder Loans (including all accrued interest).

The respective repayment claims of the Seller under the Shareholder Loans including interest as of 29 April 2026 are collectively referred to as the "Shareholder Loan Repayment Claim").

G. On 30 November 2020, the Seller and the Company entered into a service agreement, pursuant to which the Company provided certain services to the Seller ("Pre-Restructuring Service Agreement"). After the Seller and the Company applied for self-administration proceedings in May 2023, a restructuring was carried out following Seller’s withdrawal of its application for preliminary self-administration proceedings and Company’s exit from its self-administration proceedings (the "Restructuring").

On 1 May 2021, the Seller and the Company entered into a sublease agreement relating to the Premises (the "Sublease Agreement").

I. The Purchasers intend to acquire the Shares and the Shareholder Loan Repayment Claim from the Seller and the Seller intends to sell and transfer the Shares and the Shareholder Loan Repayment Claim to the Purchasers ("Transaction").

J. As part of the Transaction, the Corporate Services Agreement shall be terminated with effect as of 30 April 2026. The Company shall continue to provide certain limited financial and reporting information of the Company to the Seller, to the extent reasonably required for the Seller to fulfill certain tax and regulatory requirements following the Transaction.

K. Furthermore, as part of the Transaction, the Parties intend to agree on the procedure to achieve that the Company takes over the Lease Agreement for the Premises in course of which the Seller is intended to be released from any liabilities and obligations under the Lease Agreement.

Now, therefore, the Parties agree as follows:

1. Sale and Transfer of the Sold Shares

1.1 Sale and Transfer of the Sold Shares

(a) The Seller hereby sells and transfers with effect in rem (abtreten mit dinglicher Wirkung) the shares with the consecutive numbers 1 to 16,794 corresponding to a share percentage of 50% of the shares in the Company and the nominal capital of the Company to Purchaser 1 and Purchaser 1 accepts this sale and transfer; and

It is the joint understanding of the Parties that the Seller shall sell and transfer all shares held by it in the Company and the Seller shall not retain any shares or other interest in the Company.

The transfers in rem (Abtretung mit dinglicher Wirkung) of the Sold shares in Sections 1.1(a) and 1.1(b) shall not be subject to a condition precedent (aufschiebende Bedingung) and take immediate effect in rem (mit sofortiger dinglicher Wirkung).

1.2 Ancillary Rights

The Sold Shares are sold and transferred together with any and all rights and obligations pertaining thereto (Nebenrechte) including the right to any undistributed profits for the current business year and for any prior business years of the Company.

1.3 Consent of the Seller, No Right of First Refusal

Pursuant to section 14 para. 1 of the articles of association of the Company, the transfer of the Sold Shares requires the approval of the Company’s shareholders with a majority of at least 80% of the share capital. In addition, pursuant to section 14 para. 2 of the articles of association of the Company the shareholders of the Company have a Right of First Refusal. As a matter of precaution: The Seller is the sole shareholder of the Company. The Seller hereby gives its consent to the Transaction. Section 14 para 2 of the articles of association is not applicable.

2. Sale and Assignment of Shareholder Loan Repayment Claim; Standstill

2.1 Sale and Assignment

The Seller hereby sells and assigns with immediate effect in rem (sofortiger Wirkung) 50 % of the Shareholder Loan Repayment Claim to the Purchaser 1 and 50 % of the Shareholder Loan Repayment Claim to the Purchaser 2, whereby an indivisible cent amount shall be allocated to Purchaser 1, which hereby each accept such sale and assignment. The Company hereby consents to such assignments. The Company and the respective Purchaser may after the notarization of this agreement enter into a separate loan agreement governing the respective part of the Shareholder Loan Repayment Claim acquired by the respective Purchaser under this Section 2.1. Such loan agreement shall not require the consent of any of the other Parties, provided that Section 2.2 remains unaffected and provided further that a qualified subordination as set out in Section 2.3 shall be included in the respective loan agreement.

3

2.2 Standstill

(a) The Purchasers hereby undertake vis-à-vis the Seller (but not vis-à-vis the Company, neither directly nor by way of a contract for the benefit of a third party (kein Vertrag zu Gunsten Dritter)) that they will not demand, enforce or otherwise seek repayment, whether fully or partly, of the Shareholder Loan Repayment Claim for a period of two years following the Signing Date.

(b) Nothing in this Clause shall be construed as a waiver or deferral (Stundung) of the Shareholder Loan Repayment Claim.

2.3 Qualified subordination (Qualifizierter Rangrücktritt)

(a) As of the Signing Date, each Purchaser, each as holder of the acquired part of the Shareholder Loan Repayment Claim, hereby subordinates, pursuant to Section 19 para. 2 sentence 2 and Section 39 para. 2 of the German Insolvency Code (“InsO”), the part of the Shareholder Loan Repayment Claim acquired by such Purchaser (including any ancillary rights (Nebenrechte) and any present and future claims for principal, interest (including default interest) and costs arising out of or in connection with the Shareholder Loans and/or the Shareholder Loan Repayment Claim) (collectively, the “Subordinated Receivables“) to the claims of all other present and future creditors of the Company (other than (i) creditors whose claims are already subordinated by agreement and rank equally with the Subordinated Receivables, and (ii) equally ranking creditors) to such extent that the Subordinated Receivables may only be asserted and satisfied after satisfaction in full of all other claims against the Company (including the claims referred to in Section 39 para. 1 nos. 1–5 InsO), but prior to shareholders’ claims for repayment of capital contributions within the meaning of Section 199 sentence 2 InsO, and only out of (i) future net profits (künftige Jahresüberschüsse), (ii) a liquidation surplus (Liquidationsüberschuss) or (iii) other free assets (sonstiges freies Vermögen) of the Company which remain after satisfaction of such other creditors and which are not required for capital maintenance purposes (the “Subordination”).

(b) The Parties agree that the Subordination shall also apply outside insolvency proceedings, i.e. prior to the opening of insolvency proceedings over the assets of the Company. Accordingly, no payment (and no enforcement) in respect of the Subordinated Receivables shall be made if and to the extent that the Company is at the relevant time unable to pay its debts as they fall due (zahlungsunfähig) or over-indebted (überschuldet) within the meaning of Sections 17 and 19 InsO, or would become unable to pay its debts as they fall due or over-indebted as a result of such payment or enforcement. For the purposes of avoiding illiquidity within the meaning of Section 17 InsO, the Subordinated Receivables shall be deemed not to be seriously demanded (nicht ernsthaft eingefordert). For the avoidance of doubt, the Purchasers shall refrain from any acts in relation to the Subordinated Receivables that would constitute, trigger or deepen any ground for insolvency of the Company under German insolvency law.

(c) The Parties agree that the Subordination constitutes neither a deferral/moratorium (Stundung) nor a waiver (Verzicht) of any Subordinated Receivables.

2.4 Termination of LoC

The Company and the Seller agree that the Seller has fulfilled all payment obligations under or in connection with the LoC.
