References to “EO” or the “Company” herein are to: (i) Juuce Limited and its subsidiaries prior to the consummation of the Proposed Business Combination and (ii) EO Charging and its subsidiaries following the consummation of the Proposed Business Combination. The contents of this presentation have not been approved by an authorised person within the meaning of the Financial Services and Markets Act 2000.

You acknowledge that the Company, FRSG, and their respective representatives are under no obligation to accept any offer or proposal by any person or entity regarding any investment or transaction. This presentation contains information of a general nature and is not, and does not purport to be, a complete description of the Company or FRSG, or to contain all information that any investor may require or consider material in respect of any evaluation of the Company.

Investors are responsible for conducting their own due diligence in respect of the information, considering the appropriateness of the information in this document having regard to their own objectives, financial situation and needs, and seeking independent financial, legal and taxation advice before proceeding with any further conversations regarding the Company and FRSG.

Forward-Looking Statements All statements contained in this presentation other than statements of historical facts, including the Company's business strategy and plans and objectives for future operations, including its financial performance, are forward-looking statements. Forward-looking statements may be identified by the use of words such as estimate, plan, project, forecast, intend, will, expect, anticipate, believe, seek, target, continue, may or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean a statement is not forward looking. Indications of, and guidance or outlook on, future earnings, dividends or financial position or performance are also forward looking statements. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially, and potentially adversely, from those expressed or implied in the forward-looking statements. Most of these factors are outside FRSG’s and the Company’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (i) the occurrence of any event, change, or other circumstances that could impact the Proposed Business Combination, give rise to the termination of the Business Combination Agreement and Plan of Reorganization (the “Business Combination Agreement”) or could otherwise cause the transaction to fail to close; (ii) the outcome of any legal proceedings that may be instituted against FRSG or the Company following the announcement of the Business Combination Agreement and the transactions contemplated therein; (iii) the inability to complete the Proposed Business Combination, including due to failure to obtain approval of the stockholders of FRSG, certain regulatory approvals, or the satisfaction of other conditions to closing in the Business Combination Agreement; ; (iv) the impact of the COVID-19 pandemic on the Company’s business and/or the ability of the parties to complete the Proposed Business Combination; (v) the inability to obtain or maintain the listing of the Company’s common shares on the Nasdaq Stock Market following the Proposed Business Combination; (vi) the risk that the Proposed Business Combination disrupts current plans and operations of the Company; (vii) the ability to recognize the anticipated benefits of the Proposed Business Combination, which may be affected by, among other things, competition, and the ability of the Company to grow and manage growth profitably and retain its key employees; (viii) costs related to the Proposed Business Combination; (ix) changes in applicable laws or regulations; and (x) the possibility that the Company or FRSG may be adversely affected by other economic, business, and/or competitive factors. The foregoing list of factors is not exclusive. Additional information concerning certain of these and other risk factors is contained in FRSG’s most recent filings with the SEC, including under the heading “Risk Factors” in the registration statement on Form F-4 filed by EO with the SEC on September 30, 2021, (SEC File No. 333-259901), as amended from time to time (the “Registration Statement”). All subsequent written and oral forward-looking statements concerning FRSG or the Company, the transactions described herein or other matters attributable to FRSG, the Company or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Each of FRSG and the Company expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in their expectations with respect thereto or any change in events, conditions, or circumstances on which any statement is based, except as required by law. Use of Projections This presentation also contains estimates and other statistical data made by independent parties and by the Company relating to market size and growth and other data about the relevant industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. None of the Company, FRSG, nor any other person makes any representation as to the accuracy or completeness of such data or undertakes any obligation to update such data after the date of this presentation. In addition, projections, assumptions and estimates of the Company's future performance and the future performance of the markets in which it operates are necessarily subject to a high degree of uncertainty and risk. Such projections, assumptions and estimates constitute forward-looking statements and are for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The inclusion of financial forecast information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. Neither the Company’s or FRSG’s independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation or any other purpose, and accordingly, none of such independent auditors has expressed any opinion or provided any other form of assurance with respect to such projections. Neither the Company nor FRSG make any representation or warranty, express or implied, as to the currency, fairness, reasonableness, correctness, accuracy, completeness or otherwise of this presentation, the contents of this presentation or any other document or information supplied (whether provided in writing or orally), or which may be supplied at any time or any opinions or projections expressed herein or therein. Nothing contained in this presentation, the information or other document shall be relied upon as a promise or a representation, whether as to the past, present or future. Financial Information and Use of Non-GAAP Financial Measures The financial information and data contained in this presentation is unaudited and does not conform to Regulation S-X. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement, registration statement, or prospectus that has been or will be filed by FRSG with the SEC. Some of the financial information and data contained in this presentation, such as EBITDA and adjusted EBITDA (see p36 of PDF), have not been prepared in accordance with United States generally accepted accounting principles or IFRS ( GAAP ). These non-GAAP financial measures (including on a projected basis) are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP. The Company believes that non-GAAP financial information may be helpful to investors because it provides consistency and comparability with past financial performance and useful supplemental information about the Company. There are a number of limitations related to the use of non-GAAP financial metrics versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP metrics differently or may use other metrics to evaluate their performance, all of which could reduce the usefulness of the Company's non-GAAP financial metrics as tools for comparison. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty without unreasonable efforts in forecasting and quantifying certain amounts that are necessary for such reconciliations. The Company urges you to not to rely on any single financial measure to evaluate the business. 1

Important Information About the Proposed Business Combination and Where to Find It In connection with the Proposed Business Combination, EO has filed the Registration Statement with the SEC, which contains a preliminary proxy statement/prospectus, in connection with the proposed transactions contemplated by the Business Combination Agreement and will mail, when available, the definitive proxy statement/prospectus and other relevant documents to its stockholders. FRSG and the Company urge investors, stockholders and other interested persons to read the preliminary proxy statement/prospectus that forms a part of the Registration Statement, the amendments thereto, and, when available, the effective Registration Statement and definitive proxy statement/prospectus in connection with FRSG’s solicitation of proxies for the FRSG stockholders’ meeting because those documents will contain important information about the Proposed Business Combination.
