G2K Group GmbH

2023 RESTRICTED STOCK UNIT PLAN

1. PURPOSE. The purpose of this Plan is to provide incentives to attract, retain, and motivate eligible persons whose present and potential contributions are important to the success of the Company, and any Parents, Subsidiaries, and Affiliates that exist now or in the future, by offering them an opportunity to participate in the Company’s future performance through the grant of Awards. This Plan provides for the grant of Restricted Stock Units to acquire Shares. Capitalized terms not defined elsewhere in the text are defined in Section 18.

2. SHARES SUBJECT TO THE PLAN

2.1 Number of Shares Available. Subject to Sections 2.3 and 12 and any other applicable provisions hereof, the total number of Shares which may be available for grant and issuance pursuant to this Plan as of the Effective Date, may not exceed 10,000,000 Shares, representing the number of Shares undertaken by shareholders of the Company to be issued. Prior to any settlement of Awards under this Plan, the Company will reserve and keep available a sufficient number of Shares as will be required to satisfy the requirements of all outstanding Awards granted under this Plan. Shares offered under this Plan may be authorized but unissued Shares or Shares the shareholders of the Company have undertaken to issue.

2.2 Lapsed, Returned Awards. Shares subject to Awards, and Shares issued under the Plan under any Award, will again be available for grant and issuance in connection with subsequent Awards under this Plan to the extent such Shares (a) are subject to Awards granted under this Plan that are forfeited to or repurchased by the Company or (b) are subject to Awards granted under this Plan that otherwise terminate without such Shares being issued. In the event that Participant tenders or the Company withholds Shares to pay the withholding taxes due upon the settlement of an Award, (i) the full number of Shares, including such number of Shares used to pay the withholding taxes, shall reduce the Number of Shares available for issuance under the Plan and (ii) such number of Shares used to pay the withholding taxes shall not be added to the Shares authorized for grant under the Plan.

2.3 Adjustment of Shares. If the number or class of outstanding Shares is changed by a stock dividend, extraordinary dividend or distribution (whether in cash, shares, or other property, other than a regular cash dividend), recapitalization, stock split, reverse stock split, subdivision, combination, consolidation, reclassification, spin-off, or similar change in the capital structure of the Company, without consideration, then the number and class of Shares reserved for issuance and future grant under the Plan set forth in Section 2.1, and the number and class of Shares subject to other outstanding Awards, in each case, will be proportionately adjusted, subject to any required action by the shareholders of the Company and in compliance with applicable securities laws. Furthermore, if the Company's share capital (Stammkapital) is increased by a recapitalization from the Company's funds (Kapitalerhöhung aus Gesellschaftsmitteln), or if the Company's share capital (Stammkapital) is decreased (Kapitalherabsetzung) without a distribution of the Company's funds, or in the event of any other change in the Parent’s registered share capital (Stammkapital) without consideration affecting the Shares, then the number and class of Shares reserved for issuance and future grant under the Plan set forth in Section 2.1, and the number and class of Shares subject to other outstanding Awards, in each case, will be proportionately adjusted, subject to any required action by the shareholders of the Company and in compliance with applicable securities laws.

3 ELIGIBILITY. Awards may be granted to Employees, Consultants and Managing Directors, provided that such Consultants and Managing Directors render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction.

5 RESTRICTED STOCK UNITS. The Awards granted pursuant to this Plan represent Restricted Stock Units. A Restricted Stock Unit (“RSU”) is an award to an eligible Employee, Consultant or Managing Director covering a number of Shares that may be settled by issuance of those Shares . All RSUs will be made pursuant to the Award Agreement.

5.1 Terms of RSUs. The Managing Directors will determine the terms of an RSU including, without limitation: (a) the number of Shares subject to the RSU, (b) the time or times during which the RSU may be settled, (c) the consideration to be distributed on settlement, and (d) the effect of the Participant’s termination of Service on each RSU, provided that no RSU will have a term longer than ten (10) years.

5.2 Form and Timing of Settlement. Payment of earned RSUs will be made as soon as practicable after the date(s) determined by the Managing Directors and set forth in the Award Agreement. The Managing Directors, in their sole discretion, may settle earned RSUs in cash, Shares or a combination of both.

5.3 Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date Participant’s Service terminates (unless determined otherwise by the Managing Directors).

5.4 Payment for Restricted Stock Units. Except for the payment of the mandatory par value of EUR 1.00 (in words: Euro one) for the subscription of each Share of the Company that becomes issuable under this Plan (the “Par Value Payment”) no cash consideration shall be required of the Participant in connection with the grant of Restricted Stock Units.

5.5 Vesting. Each Award Agreement shall specify the vesting requirements applicable to the Restricted Stock Units subject thereto, which the Managing Directors shall determine in their sole discretion.

6 TAXES. Whenever a tax event occurs in relation to an Award under the Plan, the Company may require the Participant to remit to the Company, or to the Parent, Subsidiary, or Affiliate, as applicable, employing the Participant an amount sufficient to satisfy applicable income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items (the “Tax-Related Items”) legally due from the Participant prior to the delivery of Shares pursuant to settlement of any Award.

7. TRANSFERABILITY. Unless determined otherwise by the Managing Directors, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution. If the Managing Directors make an Award transferable, including, without limitation, by instrument to an inter vivos or testamentary trust in which the Awards are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or by domestic relations order to a Permitted Transferee, such Award will contain such additional terms and conditions as the Managing Directors deem appropriate.

8. VOTING AND DIVIDENDS. No Participant will have any of the rights of a shareholder with respect to any Shares until the Shares are issued to and duly subscribed by the Participant. After Shares are issued to and duly subscribed by the Participant, the Participant will be a shareholder and have all the rights of a shareholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares.

9. CERTIFICATES. All Shares or other securities whether or not certificated, delivered under this Plan will be subject to such stock transfer orders, legends, and other restrictions as the Managing Directors may deem necessary or advisable, including restrictions under any applicable federal, state, or foreign securities law, or any rules, regulations, and other requirements of any stock exchange or automated quotation system upon which the Shares may be listed or quoted.

10. APPLICABLE LAW AND OTHER REGULATORY COMPLIANCE. The grant of an Award to a Participant will not be effective unless the grant of such Award is in compliance with all applicable laws, rules, and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable and/or (b) completion of any registration or other qualification of such Shares under applicable laws or ruling of any governmental body that the Company determines to be necessary or advisable.

11. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent, Subsidiary, or Affiliate or limit in any way the right of the Company or any Parent, Subsidiary, or Affiliate to terminate Participant’s employment or other relationship at any time.

12. CORPORATE TRANSACTIONS.

12.1 Assumption or Replacement of Awards by Successor Corporation. In the event of a Corporate Transaction any or all outstanding Awards shall be treated in the manner described in the definitive transaction agreement (or, in the event the transaction does not entail a definitive agreement to which the Company is party, in the manner determined by the Managing Directors in their capacity as administrator of the Plan, with such determination having final and binding effect on all parties), which agreement or determination need not treat all Awards (or all portions of an Award) in an identical manner. The treatment specified in the transaction agreement or as determined by the Managing Directors may include (without limitation) one or more of the following with respect to each outstanding Award, subject to obtaining any required consents from the affected Participant and/or the successor or acquiring corporation (if any) to the extent required by German or other applicable law: (i) the Successor Corporation may assume or replace the Plan, which assumption or replacement shall be binding on all Participants; (ii) the Successor Corporation may substitute equivalent Awards or provide substantially similar consideration to Participants as was provided to shareholders (after taking into account the existing provisions of the Awards); and (iii) the successor corporation may also issue, in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions no less favorable to the Participant.

In the event such successor or acquiring corporation (if any) refuses to assume, convert, replace or substitute Awards, as provided above, pursuant to a Corporate Transaction, then notwithstanding any other provision in this Plan to the contrary, such Awards shall have their vesting accelerate as to all shares subject to such Award (and any applicable right of repurchase fully lapse) immediately prior to the Corporate Transaction and then such Awards will terminate.

Awards need not be treated similarly in a Corporate Transaction and treatment may vary from Award to Award and/or from Participant to Participant.

13. GOVERNING LAW. This Plan and all Awards granted hereunder, including the applicable Award Agreement(s), will be governed by and construed in accordance with the laws of Germany.

14. AMENDMENT OR TERMINATION OF PLAN, SHAREHOLDER APPROVAL. The Managing Directors may at any time terminate or amend this Plan in any respect, including, without limitation, amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan, provided, however, that the Managing Directors will not, without the approval of the shareholders of the Company, amend this Plan in any manner that requires such shareholder approval, provided further that a Participant’s Award will be governed by the version of this Plan then in effect at the time such Award was granted. No termination or amendment of the Plan will affect any then- outstanding Award unless expressly provided by the Managing Directors. In any event, no termination or amendment of the Plan or any outstanding Award may adversely affect any then outstanding Award without the consent of the Participant, unless such termination or amendment is necessary to comply with applicable law, regulation, or rule. To the extent require by applicable law, the Plan, or any amendment thereto, will be subject to the approval of the Company's shareholders prior to its adoption or any amendment thereto.

15. INSIDER TRADING POLICY. Each Participant who receives an Award will comply with any policy adopted by the Company from time to time covering transactions in the Company’s securities by Employees, officers, and/or Directors of the Company, as well as with any applicable insider trading or market abuse laws to which the Participant may be subject.

16. ALL AWARDS SUBJECT TO COMPANY CLAWBACK OR RECOUPMENT POLICY. All Awards, subject to applicable law, will be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Managing Directors or required by law during the term of Participant’s employment or other service with the Company that is applicable to officers, Employees, Directors or other service providers of the Company, and in addition to any other remedies available under such policy and applicable law, may require the cancellation of outstanding Awards and the recoupment of any gains realized with respect to Awards.
