(the “Company”) and NextGen Acquisition Corporation ("NextGen") and is being provided solely for use in evaluating or pursuing a business relationship between the parties where the receiving party (“Receiving Party”) may be engaged to act as a provider of strategic support to the Company, including as an underwriter, strategic adviser or other similar role (the “Permitted Use”) or as an equity provider and is not to be used for any other purpose. The Pack is being delivered to a limited number of Receiving Parties who have entered into a Confidentiality Agreement with the Company. The Receiving Party acknowledges and agrees that the Pack and all information pertaining thereto are strictly private and confidential and proprietary to the Company. Except as expressly permitted by or otherwise authorized by the Company and NextGen, the Receiving Party shall keep the Pack and all information pertaining thereto confidential in accordance with the terms of the Confidentiality Agreement. The Receiving Party understands and agrees that the Company and NextGen have not made any, and make no representation or warranty, express or implied, herein as to the accuracy or completeness of the Pack. To the fullest extent permitted by law, in no circumstances will the Company or NextGen or any of their respective subsidiaries, stockholders, affiliates, representatives, partners, directors, officers, employees, advisers or agents be responsible or liable for any direct, indirect or consequential loss or loss of profit arising from the use of the Pack, its contents, its omissions, reliance on the information contained within it, or on opinions communicated in relation thereto or otherwise arising in connection therewith. The Company is providing Confidential Information on an “as is” basis for use by the Receiving Party at its own risk. The Company and NextGen disclaim all warranties, whether express, implied or statutory, including, without limitation, any implied warranties of title, non - infringement of third - party rights, merchantability, or fitness for a particular purpose. The Pack discusses trends and markets that the Company’s leadership team believes will impact the development and success of the Company based on its current understanding of the marketplace. Industry and market data used in the Pack have been obtained from third - party industry publications and sources as well as from research reports prepared for other purposes. The Company and NextGen have not independently verified the data obtained from these sources and cannot assure you of the data’s accuracy or completeness. This data is subject to change. In addition, this Pack does not purport to be all - inclusive or to contain all of the information that may be required to make a full analysis of the Company or the proposed business combination. The Receiving Party should make its own evaluation of the Company and of the relevance and adequacy of the information and should make such other investigations as it deems necessary. Nothing in this agreement imposes on the Company or NextGen any obligation to provide further Packs or update or correct any inaccuracies in the Pack. Forward - Looking Statement The Pack includes “forward - looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward - looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “would,” “should,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. “Forward - looking statements” include all statements about the Company’s or NextGen's future plans and performance, regardless of whether the foregoing expressions are used to identify them. In addition, these forward - looking statements include, but are not limited to, statements regarding: estimates and forecasts of financial and performance metrics; projections of market opportunity and market share, expectations and timing related to product development and launches; the implementation and potential success of the Company's go - to - market strategy; the Company’s research and development efforts; and the Company’s proposed manufacturing plans and expectations, including statements regarding the effectiveness and efficiency of its future manufacturing processes. These statements are based on various assumptions, whether or not identified in the Pack, and on the current expectations, beliefs, intentions or strategies of the Company’s management and are not predictions of actual performance. These forward - looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Company or NextGen. These forward - looking statements are subject to a number of judgments, risks and uncertainties, including risks relating to: (i) changes in domestic and foreign business, market, financial, political and legal conditions; (ii) the uncertainty of the Company’s projected financial information; (iii) the rollout of the Company’s business and the timing of expected business milestones, including product development and launches, market acceptance of its planned products and services and achieving sufficient production volumes at acceptable quality levels and prices; (iv) future market adoption and industry acceptance of the Company's products and services; (v) the Company's go - to - market strategy; (vi) the timing of the completion of the Company’s commercial - scale manufacturing capabilities; (vii) the Company’s ability to achieve its intellectual property objectives and to patent its technology; (viii) the Company’s ability to obtain expected or required regulatory certifications and authorizations; (ix) the ability and timely consummation of the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of the Company or NextGen is not obtained, (x) failure to realize 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; (xi) the Company’s ability to obtain a favorable outcome in the industry standards setting system; (xii) the effects of competition and the abilities and rights of third parties on the Company’s business and operations; (xiii) the need for, timing and availability of additional financing and the Company’s ability access to additional capital; (xiv) the amount of redemption requests made by NextGen’s public stockholders; the ability of NextGen or the combined company to issue equity or equity - linked securities in connection with the proposed business combination or in the future; and (xv) the risks and uncertainties described in the “Risk Factors” section of NextGen’s registration statement on Form S - 1, the proxy statement/prospectus on Form S - 4 relating to the business combination, which is expected to be filed by NextGen with the Securities and Exchange Commission (the “SEC”) and other documents filed by NextGen from time to time with the SEC. If any of these risks materialize or if the Company’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward - looking statements. There may be additional risks that are not presently known to the Company or NextGen or that the Company or NextGen currently believes are immaterial that could also cause actual results to differ from those contained in the forward - looking statements. In addition, forward - looking statements reflect the Company’s and NextGen’s expectations, plans or forecasts of future events and views as of the date of this Pack. Forward - looking statements speak only as of the date they are made, and the Company and NextGen undertake no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward - looking statements, whether as the result of new information, future events or otherwise, except as required by law. These forward - looking statements should not be relied upon as representing the Company’s or NextGen’s assessments as of any date subsequent to the date of the Pack. Accordingly, undue reliance should not be placed upon the forward - looking statements. Please consider the environment before printing this presentation. DISCLAIMER Confidential and Privileged, Property of Xos, Inc. 2

Use of Projections and Description of Key Partnerships The Pack contains projected financial information with respect to the Company, namely revenue, gross profit, operating capital expenditures, Adjusted EBIT, Adjusted EBITDA, EBITDA margin and Net Working Capital for 2020 – 2025. Such projected financial information constitutes forward - looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. See “Forward - Looking Statements” above. Actual results may differ materially from the results contemplated by the projected financial information contained in the Pack, and the inclusion of such information in the Pack should not be regarded as a representation by any person that the results reflected in such projections will be achieved. The independent registered public accounting firm of the Company has not audited, reviewed, compiled, or performed any procedures with respect to the projections for the purpose of their inclusion in the Pack, and accordingly, does not express an opinion or provided any other form of assurance with respect thereto for the purpose of the Pack. The Pack contains descriptions of certain key business partnerships of the Company. These descriptions are based on the Company’s management team’s discussions with such counterparties and the latest available information and estimates as of the date of the Pack. In certain cases, such descriptions are subject to negotiation and execution of definitive agreements with such counterparties which have not been completed as of the date of the Pack and, as a result, such descriptions of key business partnerships of the Company, remain subject to change. Financial Information; Non - GAAP Financial Measures The financial information and data contained in the Pack is unaudited and does not conform to Regulation S - X. Some of the financial information and data contained in the Pack, such as EBITDA and EBITDA margin, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). EBITDA is defined as net earnings (loss) before interest expense, income tax expense (benefit), depreciation and amortization. The Company believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors. Management does not consider these non - GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP financial measures. In order to compensate for these limitations, management presents non - GAAP financial measures in connection with GAAP results. The Company is not providing a reconciliation of projected EBITDA for full years 2020 – 2025 to the most directly comparable measure prepared in accordance with GAAP because the Company is unable to provide this reconciliation without unreasonable effort due to the uncertainty and inherent difficulty of predicting the occurrence, the financial impact, and the periods in which the adjustments may be recognized. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results. In addition, all the Company historical financial information included herein is preliminary and subject to change pending finalization of the 2020 audit of the Company in accordance with PCAOB auditing standards. No Offer or Solicitation The Pack does not constitute an offer to sell or the solicitation of an offer to buy any securities, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale wou ld be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. Investment in any securities described herein has not been approved or disapproved by the SEC or any other regulatory authority nor has any authority passed upon or endorsed the merits of the offering or the accuracy or adequacy of the information contained herein. Any representation to the contrary is a criminal offense. Trademarks The Pack contains trademarks, service marks, trade names and copyrights of the Company and other companies, which are the property of their respective owners. The use or display of third parties’ trademarks, service marks, trade names or products in the Pack is not intended to, and does not imply, a relationship with the Company or NextGen, or an endorsement or sponsorship by or of the Company or NextGen. Solely for convenience, the trademarks, service marks, trade names and copyrights referred to in the Pack may appear without the TM, SM, ® or © symbols, but such references are not intended to indicate, in any way, that the Company or NextGen will not assert, to the fullest extent under applicable law, their rights to these trademarks, service marks, trade names and copyrights. Additional Information; Participants in the Solicitation If the contemplated business combination is pursued, NextGen will be required to file a preliminary and definitive proxy statement, which may include a registration statement, and other relevant documents with the SEC. Shareholders and other interested persons are urged to read the proxy statement and any other relevant documents filed with the SEC when they become available because they will contain important information about the Company, NextGen and the contemplated business combination. Shareholders will be able to obtain a free copy of the proxy statement (when filed), as well as other filings containing information about the Company, NextGen and the contemplated business combination, without charge, at the SEC’s website located at www.sec.gov. NextGen and its directors and executive officers may be deemed to be participants in the solicitation of proxies from NextGen's shareholders in connection with the proposed transaction. A list of the names of such directors and executive officers and information regarding their interests in the business combination will be contained in the proxy statement/prospectus when available. You may obtain free copies of these documents as described in the preceding paragraph. The Pack does not contain all the information that should be considered in the contemplated business combination. It is not intended to form any basis of any investment decision or any decision in respect to the contemplated business combination. The definitive proxy statement will be mailed to shareholders as of a record date to be established for voting on the contemplated business combination when it becomes available. Please consider the environment before printing this presentation. DISCLAIMER Confidential and Privileged, Property of Xos, Inc. 3

The list below of risk factors has been prepared solely for purposes of the proposed private placement transaction (the “Private Placement”) as part of the proposed business combination of NextGen Acquisition Corporation (“NextGen”) and Xos, Inc. (the “Business Combination”), and solely for potential investors in the Private Placement, and not for any other purpose. All references to “Xos,” the “Company,” “we,” “us” or “our” refer to the business of Xos, Inc. and its consolidated subsidiaries. The risks presented below are certain of the general risks related to the business of the Company, the Private Placement and the Business Combination, and such list is not exhaustive. The list below is qualified in its entirety by disclosures contained in future documents filed or furnished by the Company and NextGen, with the U.S. Securities and Exchange Commission (“SEC”), including the documents filed or furnished in connection with the proposed transactions between the Company and NextGen. The risks presented in such filings will be consistent with those that would be required for a public company in its SEC filings, including with respect to the business and securities of the Company and NextGen and the proposed transactions between the Company and NextGen, and may differ significantly from and be more extensive than those presented below. Investing in securities (the “Securities”) to be issued in connection with the Business Combination involves a high degree of risk. You should carefully consider these risks and uncertainties, together with the information in the Company’s consolidated financial statements and related notes, and should carry out your own due diligence and consult with your own financial and legal advisors concerning the risks and suitability of an investment in the Private Placement, before making an investment decision. There are many risks that could affect the business and results of operations of the Company, many of which are beyond its control. If any of these risks or uncertainties occurs, the Company’s business, financial condition and/or operating results could be materially and adversely harmed. Additional risks and uncertainties not currently known or those currently viewed to be immaterial may also materially and adversely affect the Company’s business, financial condition and/or operating results. If any of these risks or uncertainties actually occurs, the value of the Company’s equity securities may decline, and any investor in the Offering may lose all or part of its investment. Risks Related to our Business and our Industry ● Capital Requirements and Cost Fluctuations . We require significant capital to develop and grow our business, including with respect to the design, development, marketing, distribution and sale of our goods and services. Increased costs associated with the operation of our business, the disruption of our supply chain or a shortage of materials (including, without limitation, a change in the price or availability of lithium - ion battery cells and their component parts) could harm our business. Our financial results may be significantly and negatively impacted from period to period due to the aforementioned fluctuations in operating costs and other factors. ● Financial Condition and Potential Dilution . We are an early stage company with a history of losses. We could incur significant expenses and continued losses for the foreseeable future. We have yet to achieve positive operating cash flow and our ability to generate positive cash flow is uncertain. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown events which may result in our inability to achieve or maintain profitability. In addition, our operational and financial results forecasts rely in large part upon assumptions and analyses developed by us. If these assumptions or analyses prove to be incorrect, in whole or in part, our actual operational and financial results may be materially different from forecasted results. Our future capital needs may require us to sell additional equity or debt securities that may dilute our stockholders or introduce covenants that may restrict our operations or our ability to pay dividends. ● Limited Operational History and Competitive Landscape . Our limited operating history makes evaluating our business and future prospects difficult and may increase the risk of your investment. Our ability to develop and manufacture EVs and their component parts of sufficient quality and appeal to customers on schedule and on a large scale is still unproven and continues to evolve. Our limited operational history may hinder our ability to anticipate and timely adapt to increases or decreases in revenues or experiences significant and unanticipated delays in the design, production and launch of our goods and services. Our business, prospects, financial condition and operating results could experience significant harm as a result. We also face a competitive market with respect to our goods and services and may therefore not be successful in competing within the industry. There may also be significant developments in alternative technologies, such as advanced diesel, ethanol, or compressed natural gas or improvements in the fuel economy of the internal combustion engine, which may materially and adversely affect our business and prospects in ways we do not currently anticipate. ● Business Development and Partnerships . Certain of our strategic, development and deployment arrangements or expected arrangements could be terminated or may not materialize into contract partnership arrangements on a long - term basis or at all. We may also not be able to successfully engage target customers or convert early trial deployments with truck fleets into meaningful orders or additional deployments in the future. If we fail to manage or develop our partnerships and customer growth effectively, including failing to attract and integrate qualified personnel, we may not be able to design, develop, manufacture, market and launch our EVs and related products successfully. ● Suppliers. We rely on suppliers, some of which are limited source suppliers, for necessary components of our vehicles and outsourced partners for the manufacturing of our vehicles and component parts. A loss of any of these partners or defects in or failure of the products that they supply to us could negatively affect our business. ● Insurance . We maintain certain levels of insurance; we may, however, face claims from time - to - time that could exceed our insurance coverage or not fall within our coverage. ● Forecasts . Our operating and financial result forecasts rely in large part upon assumptions and analyses developed by us. If these assumptions and analyses prove to be incorrect, our actual operating results may differ materially. Risks Related to the Private Placement ● Capital Raise . There can be no assurance that NextGen will be able to raise sufficient capital in the Private Placement to consummate the Business Combination or for use by the combined company following the Business Combination (the “Combined Company”). ● Voting Power. The issuance of shares of the Combined Company’s securities in connection with the Private Placement will dilute substantially the voting power of Combined Company’s shareholders. RISK FACTORS Confidential and Privileged, Property of Xos, Inc. 44

RISK FACTORS Risks Related to the Business Combination ● Transaction Costs. Both NextGen and Xos will incur significant transaction costs in connection with the Business Combination. ● Contingencies of Business Combination. The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed. ● Key Personnel. The ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate the business thereafter will be largely dependent upon the efforts of certain key personnel of Xos, all of whom we expect to stay with the Combined Company following the Business Combination. The loss of such key personnel could negatively impact the operations and financial results of the combined business. ● Redemption. There is no assurance that a shareholder’s decision whether to redeem its shares for a pro rata portion of the Trust Account will put the shareholder in a better future economic position. ● Value of Securities. If the Business Combination’s benefits do not meet the expectations of investors or securities analysts, the market price of NextGen’s securities or, following the consummation of the Business Combination, the value of the Combined Company’s securities, may decline. ● Stock Exchange Approval. There can be no assurance that the Combined Company’s securities will be approved for listing on the chosen stock exchange or that the Combined Company will be able to comply with the continued listing standards of such stock exchange. ● Legal Proceedings. Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination. ● COVID - 19. The Business Combination or Combined Company may be materially adversely affected by the recent COVID - 19 outbreak. ● Compliance with Laws. Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect Xos’ and the Combined Company’s business, including NextGen’s and Xos’ ability to consummate the Business Combination, and results of operations.
