WHEREAS, each Shareholder is, as of the date of this Agreement, the sole legal and beneficial owner of: (i) such number of fully-paid ordinary shares of GBP 0.00001 each in the Company (“Company Shares”); and (ii) such number of warrants in the Company (“Company Warrants”), set forth opposite such Shareholder’s name on Schedule 1 under the heading “Company Shares” and “Company Warrants” respectively.

WHEREAS, PubCo, the Company, CIIG Capital Partners II, Inc., a Delaware corporation (“SPAC”) and Zapp Electric Vehicles, Inc. are entering into an Agreement and Plan of Merger (the “Merger Agreement”) dated as of November     , 2022, providing for, inter alia, each Shareholder’s transfer of its respective Company Shares and Company Warrants to PubCo in exchange for newly issued ordinary shares, with $0.0001 par value per share, of PubCo (“PubCo Shares”) and warrants in PubCo (“PubCo Exchange Warrants”) (as applicable) on the terms and subject to the conditions of this Agreement;

NOW THEREFORE, intending to be legally bound, as a condition and inducement to the entry into and performance of the Merger Agreement, in consideration of the mutual covenants and agreements herein contained, and for other good and valuable consideration, the Parties hereby agree as follows:

1. DEFINITIONS; INTERPRETATION

Unless otherwise expressly indicated, capitalized terms used but not defined in this Agreement have the meanings ascribed to such terms in the Merger Agreement, and this Agreement shall be interpreted and applied in accordance with the rules of construction applicable to the Merger Agreement, mutatis mutandis.

2. SHARE AND WARRANT EXCHANGE

2.1 Acquisition. On the Closing Date (and immediately prior to the Effective Time), and upon the terms and conditions of this Agreement and the Merger Agreement, the Shareholders shall sell and transfer to PubCo, and PubCo shall purchase from the Shareholders, all of the legal and beneficial title to the Company Shares and Company Warrants set out in Schedule 1 with full title guarantee, free from all Liens and together with all rights attaching to the Company Shares and Company Warrants, respectively, at the Closing (which, for the avoidance of doubt, shall be immediately prior to the Effective Time of the Merger).

2.2 Initial Consideration. Subject to Section 2.4, the aggregate consideration to be paid to each Shareholder in respect of the transfer of its Company Shares and Company Warrants to PubCo at the Closing shall be the due issuance and allotment to such Shareholder of that number of PubCo Shares and PubCo Exchange Warrants, credited as fully paid, set out opposite such Shareholder’s name on Schedule 1 under the heading “PubCo Shares” and “PubCo Exchange Warrants” respectively.

2.3 Exchange Deliveries. At the Closing, each Shareholder shall deliver or procure the delivery to PubCo of:

(a) a duly executed stock transfer form in the form attached hereto as Exhibit A in respect of its Company Shares to effect the transfer of its Company Shares to PubCo (a “STF”); and

(b) any and all share certificates representing its Company Shares;

and the Company shall deliver to PubCo a copy of the executed resolution of the Company board of directors approving (x) the form of the STF and the transfer of the Company Shares to PubCo, (y) PubCo’s entry in the register of members as the sole holder of all such Shareholder’s Company Shares (subject to the completion of any applicable UK stamp duty formalities), and (z) the necessary filings and notifications in connection with the aforementioned matters. In the event that a Shareholder does not deliver share certificates in respect of its Company Shares to PubCo in accordance with this Section 2.3, if and to the extent a share certificate has previously been issued by the Company, such Shareholder severally agrees to indemnify PubCo (to the extent permitted by law) and the Company from and against all claims, actions, proceedings and demands which may be brought against PubCo and the Company and all losses, liabilities, charges, costs, damages and expenses which PubCo or the Company may suffer or reasonably incur, in each case as a result of allowing the registration of the transfer of all or any part of such Shareholder’s Company Shares without the production of the original share certificates.

2.4 Earnout.

(a) A Shareholder’s right to receive Earnout Shares pursuant to this Section 2.4, if any, is subject to the closing price of PubCo Shares equaling or exceeding, for any 20 trading days during a 30 consecutive trading day period, (i) $12.00 per share (the “First Earnout Condition”), (ii) $14.00 per share (the “Second Earnout Condition”) or (iii) $16.00 per share (the “Third Earnout Condition”; and each of the First, Second and Third Earnout Conditions an “Earnout Condition”), as applicable, in each case as equitably adjusted for share splits, share dividends, reorganizations and recapitalisations.

(b) As additional consideration for the transfer of Company Shares to PubCo pursuant to this Section 2, as promptly as reasonably practicable (but in any event, within ten Business Days) after the satisfaction of an Earnout Condition, PubCo shall issue and allot or cause to be issued and allotted to each applicable Shareholder the applicable Earnout Shares.

(c) In the event that an Earnout Condition is not satisfied prior to the fifth anniversary of the Closing, the contingent right and entitlement of such Shareholders to the applicable Earnout Shares shall be forfeited and cease to exist.

(d) Any issuance of Earnout Shares shall be treated as an adjustment to the consideration paid at the Closing, except to the extent otherwise required by Law, and an amount equal to the aggregate par value of the Earnout Shares so issued will be credited to the capital account of PubCo.

(e) To the extent that, prior to the fifth anniversary of the Closing, there is a bona fide third party transaction that results in PubCo Shares being converted into the right to receive cash or other consideration having a per share value (as adjusted for share splits, share dividends, reorganizations and recapitalisations, and in the case of any non-cash consideration, as provided in the definitive transactions documents for such transaction, or if not so provided, determined by the board of directors of PubCo in good faith) (i) equal to or in excess of any Earnout Condition that has not yet been satisfied, then the applicable Earnout Shares shall be issued to the relevant Shareholders effective as of immediately prior to the consummation of such transaction, or otherwise treated as so issued in connection therewith, so as to ensure that the recipients of such Earnout Shares shall receive such Earnout Shares, and all proceeds thereof, in connection with such transaction, and (ii) less than any Earnout Condition that has not yet been satisfied, then the contingent right and entitlement of such Shareholders to the applicable Earnout Shares shall be forfeited and cease to exist.

6.9 Adjustment of Schedule 1. If any Shareholder has reason to believe that its record or beneficial ownership of Subject Shares differs from the number of Company Shares and Company Warrants set forth on Schedule 1, such Shareholder shall promptly notify PubCo and the Company, and Schedule 1 shall be updated to reflect the same.

This document contains certain forward-looking statements within the meaning of U.S. federal securities laws with respect to the proposed business combination (the “Business Combination”) between Zapp Electric Vehicles Limited (“Zapp”), Zapp Electric Vehicles Group Limited (“PubCo”) and CIIG Capital Partners II, Inc. (“CIIG II”), including statements regarding the benefits of the transaction, the anticipated timing of the transaction, the anticipated growth in the industry in which Zapp operates and anticipated growth in demand for Zapp’s products, projections of Zapp’s future financial results and possible growth opportunities for Zapp. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “budget,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this document, including but not limited to: (i) the risk that the transaction may not be completed in a timely manner or at all, which may adversely affect the price of CIIG II’s securities, (ii) the risk that the transaction may not be completed by CIIG II’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by CIIG II, (iii) the failure to satisfy the conditions to the consummation of the transaction, including the adoption of the business combination agreement by the stockholders of CIIG II, (iv) the lack of a third party valuation in determining whether or not to pursue the proposed Business Combination, (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the business combination agreement, (vi) the effect of the announcement or pendency of the transaction on Zapp’s business relationships, performance, and business generally, (vii) risks that the proposed Business Combination disrupts current plans of Zapp or diverts management’s attention from Zapp’s ongoing business operations and potential difficulties in Zapp’s employee retention as a result of the proposed Business Combination, (viii) the outcome of any legal proceedings that may be instituted against Zapp, PubCo, CIIG II or their respective directors or officers related to the proposed Business Combination, (ix) the ability of PubCo, CIIG II or a successor thereto to maintain the listing of its securities on The Nasdaq Stock Market LLC, (x) volatility in the price of the securities of PubCo, CIIG II or a successor thereto due to a variety of factors, including changes in the competitive and highly regulated industries in which Zapp plans to operate, variations in performance across competitors, changes in laws and regulations affecting Zapp’s business and changes in the combined capital structure, (xi) the ability to implement business plans, forecasts, and other expectations after the completion of the proposed Business Combination, and identify and realize additional opportunities, (xii) the risk of downturns in the highly competitive electric vehicle industry, (xiii) the ability of Zapp to build the Zapp brand and consumers’ recognition, acceptance and adoption of the Zapp brand, (xiv) the risk that Zapp may be unable to develop and manufacture electric vehicles of sufficient quality and on schedule and scale, that would appeal to a large customer base, (xv) the risk that Zapp has a limited operating history, has not yet released a commercially available electric vehicle and does not have experience manufacturing or selling a commercial product at scale and (xvi) the risk that Zapp may not be able to effectively manage its growth, including its design, research, development and maintenance capabilities.

The foregoing list of factors is not exhaustive. Forward-looking statements are not guarantees of future performance. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of PubCo’s registration statement on Form F-4, the proxy statement/prospectus discussed below, CIIG II’s Annual Report on Form 10-K and Quarterly Report on Form 10-Q and other documents filed by PubCo, CIIG II or a successor thereto from time to time with the U.S. Securities and Exchange Commission (the “SEC”). These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. The forward-looking statements in this document represent the views of Zapp, PubCo and CIIG II as of the date of this document. Subsequent events and developments may cause that view to change. Readers are cautioned not to put undue reliance on forward-looking statements, and all forward-looking statements in this document are qualified by these cautionary statements. Zapp, PubCo and CIIG II assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of Zapp, PubCo nor CIIG II gives any assurance that Zapp, PubCo or CIIG II will achieve its expectations. The inclusion of any statement in this document does not constitute an admission by Zapp, PubCo or CIIG II or any other person that the events or circumstances described in such statement are material.
