Risk Factors OCTOBER 2021 52 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATING TO TEMPO'S BUSINESS AND INDUSTRY • We are an early - stage company with a history of losses. We have not been profitable historically and may not achieve or maintain profitability in the future. • Our limited operating history and rapid growth makes evaluating our current business and future prospects difficult and may increase the risk of your investment. • The success of our business is dependent on our ability to keep pace with technological changes and competitive conditions in our industry, and our ability to effectively adapt our services as our customers react to technological changes and competitive conditions in their respective industries. We may not timely and effectively scale and adapt our existing technology, processes, and infrastructure to meet the needs of our business. • Our operating results and financial condition may fluctuate from period to period and may fall below expectations in any particular period, which could adversely affect the market price of our common stock. • We compete with numerous other diversified manufacturing service providers, electronic manufacturing services and design providers and others, and may face increasing competition, which could cause our operating results to suffer. • We are dependent on a limited number of customers and end markets. A decline in revenue from, or the loss of, any significant customer, could have a material adverse effect on our financial condition and operating results. • Customer relationships with emerging companies may present more risks than with established companies. • We may be adversely affected by supply chain issues, including shortages of required electronic components. • Our gross profit and gross margin are dependent on a number of factors, including our product mix, market prices, labor costs and availability, acquisitions we may make and our ability to achieve cost synergies, level of capacity utilization and component, material, and other services prices. • Our failure to meet our customers' price expectations may adversely affect our business and results of operations. • If demand for our products does not grow as expected, or develops more slowly than expected, our revenues may stagnate or decline, and our business may be adversely affected. • Defects in shipped products that give rise to product returns or warranty or other claims could result in material expenses, diversion of management time and attention, adversely affect customer relationships and damage to our reputation. • We may be involved in legal proceedings, including intellectual property ("IP"), anti - competition and securities litigation, employee - related claims and regulatory investigations, which could, among other things, divert efforts of management and result in significant expense and loss of our IP rights. • Our operations could suffer if we are unable to attract and retain key management or other key employees. • The effect of COVID - 19 on our operations and the operations of our customers, suppliers and logistics providers has had, and may continue to have, a material and adverse impact on our financial condition and results of operations.

Risk Factors (continued) OCTOBER 2021 53 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATING TO TEMPO'S BUSINESS AND INDUSTRY (CONTINUED) • We purchase a significant amount of the materials and components we use from a limited number of suppliers . If our suppliers become unavailable or inadequate, our customer relationships, results of operations and financial condition may be adversely affected . Our facilities, and our suppliers ' and our customers' facilities, are vulnerable to disruption due to natural or other disasters, public health crises, strikes and other events beyond our control . • Our facili ties , and our suppliers' and our customers' facilities, are vulnerable to disruption due to natural or other disasters, public health crises, strikes and other events beyond our control . • If we fail to grow our business as anticipated, our operating results will be adversely affected. If we grow as anticipated but fail to manage our operations and costs accordingly, our business may be harmed and our results of operations may suffer. • As we acquire and invest in companies or technologies, we may not realize expected business, expected cost synergies, or technological or financial benefits. The acquisitions or investments could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our business , results of operations, and financial condition. • We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all. • We could be subject to warranty and other claims involving allegedly defective products that we supply. • Failure of our global operations to comply with anti - corruption laws and various trade restrictions, such as sanctions and export controls, could have an adverse effect on our business. • Compliance or the failure to comply with current and future environmental, health and safety, product stewardship and producer responsibility laws or regulations could cause us significant expense. • We collect, use , store, or otherwise process confidential customer information, which subjects us to privacy and data security laws and contractual commitments, and our actual or perceived failure to comply with such laws and commitments could harm our business. • An inability to successfully manage the procurement, development, implementation or execution of IT systems, or to adequately maintain these systems and their security, as well as to protect data and other confidential information, may adversely affect our business and reputation. • If we experience a significant cybersecurity breach or disruption in our information systems or any of our partners' information systems, our business could be adversely affected. • We rely on our information technology systems to manage numerous aspects of our business and a disruption of these systems could adversely affect our business. • Our current levels of insurance may not be adequate for our potential liabilities. • Because our industry is rapidly evolving, forecasts of market growth in this presentation may not be accurate, and even if the markets in which we compete achieve the forecasted growth, there can be no assurance that our business will grow at similar rates, or at all. • Global economic, political and social conditions and uncertainties in the markets that we serve may adversely impact our business.

Risk Factors (continued) OCTOBER 2021 54 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATING TO TEMPO'S BUSINESS AND INDUSTRY (CONTINUED) • We are subject to taxes in numerous jurisdictions. The Company's future effective tax rates could be affected by changes in the mix of earnings in jurisdictions with differing statutory rates and changes in tax laws or their interpretation. • Our industry routinely experiences cyclical market patterns and our products are used across different end markets. A significant downturn in the industry or in any of these end markets could cause a meaningful reduction in demand for our products and harm our operating results. • Third - party lawsuits and assertions to which we are subject alleging our infringement of patents, trade secrets or other intellectual property rights may have a significant adverse effect on our financial condition. • We may incur substantial costs enforcing and defending our intellectual property rights. • If we are unable to adequately protect or enforce our intellectual property rights, such information may be used by others to compete against us. • Our internal controls over financial reporting currently do not meet all of the standards contemplated by Section 404 of the Sarbanes - Oxley Act of 2002 (the "Sarbanes - Oxley Act"), and failure to achieve and maintain effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes - Oxley Act could impair our ability to produce timely and accurate financial statements or comply with applicable regulations and have a material adverse effect on our business. • Fluctuations in the cost and availability of raw materials, equipment, labor, and transportation could cause manufacturing delays or increase our costs. • Certain software we use is from open source code sources, which, under certain circumstances could materially adversely affect our business, financial condition, and operating results. RISKS RELATED TO BECOMING A PUBLIC COMPANY • We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance and investor relations initiatives. • Members of our management team and board of directors have limited experience managing a public company. • We are an "emerging growth company" and a "smaller reporting company" and the reduced disclosure requirements applicable to emerging growth companies and smaller reporting companies may make our common stock less attractive to investors, and may make it more difficult to compare our performance with other public companies. • If we are unable to meet expectations and projections in any research or reports published by securities or industry analysts, or if securities or industry analysts do not publish research or reports or publish unfavorable research or reports about our business, our stock price and trading volume could decline, or there may be a depressed market price and limited liquidity for our securities. • If we fail to maintain proper and effective internal controls over financial reporting , our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline. • Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

Risk Factors (continued) OCTOBER 2021 55 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATED TO BECOMING A PUBLIC COMPANY (CONTINUED) • Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies. • Provisions in our proposed charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management. • Our proposed certificate of incorporation will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders and that the federal district courts shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the U.S. Securities Act of 1933, as amended, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. RISKS RELATED TO THE BUSINESS COMBINATION AND ACE • Each of ACE Convergence Acquisition Corp. ("ACE") and Tempo Automation, Inc. ("Tempo") will incur significant transaction costs in connection with the business combination between ACE and Tempo (the "Business Combination"). • The announcement of the proposed Business Combination could disrupt Tempo's relationships with its customers, suppliers, business partners and others, as well as its operating results and business generally. • The consummation of the Business Combination is subject to a number of conditions, including, among other things, the consummation of the acquisitions by Tempo of each of Whizz Systems, Inc. and Compass AC Holdings, Inc. (collectively, the "Add - on Acquisitions") and all required waiting periods or approvals under the Hart - Scott - Rodino Antitrust Improvements Act of 1976 and all applicable antitrust laws relating to the Business Combination and the Add - On Acquisitions having expired, been received or terminated , as applicable, which conditions may not be satisfied on a timely basis, if at all. If those conditions are not satisfied or waived, the merger agreement may be terminated in accordance with its terms and the Business Combination may not be completed. The Add - on Acquisitions are also subject to a number of conditions, which, if not satisfied or waived, may prevent the Business Combination from being completed. • If ACE is not able to complete the Business Combination by January 30, 2022, nor able to complete another business combination by such date, in each case, as such date may be further extended pursuant to ACE's current amended and restated memorandum of association under the Cayman Islands Companies Act and ACE's current amended and restated articles of associa tion , ACE would cease all operations except for the purpose of winding up and would redeem its Class A ordinary shares and liquidate the trust account, in which case its public shareholders may only receive approximately $10.00 per share and its warrants will expire worthless. • If the net proceeds of ACE ' s initial public offering not being held in the trust account are insufficient to allow ACE to operate through to January 30, 2022 and ACE is unable to obtain additional capital, ACE may be unable to complete its initial business combination, in which case its public shareholders may only receive $10.00 per share, and its warrants will expire worthless. • Compliance obligations under the Sarbanes - Oxley Act may make it more difficult to effectuate the Business Combination, require substantial financial and management resources and increase the time and costs of completing a business combination. • 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. The las of such key personnel could negatively impact the operations and financial results of the combined business.

Risk Factors (continued) OCTOBER 2021 56 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATED TO THE BUSINESS COMBINATION AND ACE (CONTINUED) • There is no assurance that a stockholder's decision whether to redeem its shares for a pro rata portion of ACE's trust account will put the stockholder in a better future economic position. • If the Business Combination's benefits do not meet the expectations of investors or securities analysts, the market price of ACE's securities or, following the consummation of the Business Combination, the combined company's securities, may decline. • A market for the combined company's securities may not develop, which would adversely affect the liquidity and price of such securities. • There can be no assurance that the combined company's securities will be approved for listing on the Nasdaq Stock Market LLC {"Nasdaq") or that the combined company will be able to comply with the continued listing standards of Nasdaq. • Directors of ACE have potential conflicts of interest in recommending that ACE's stockholders vote in favor of the adoption of the Business Combination. • ACE may redeem unexpired warrants prior to their exercise at a time that is disadvantageous to the holders of ACE warrants, thereby making such warrants worthless. • ACE's warrants are accounted for as liabilities and the changes in value of ACE's warrants could have a material effect on Tempo's financial results. • Even if the Business Combination is completed, there can be no assurance that ACE's warrants will be in the money during their exercise period, and they may expire worthless. • If ACE seeks stockholder approval of the Business Combination, its sponsor, directors, of ficers , advisors and their affiliates may elect to purchase shares or warrants from public stockholders, which may influence a vote on the Business Combination and reduce the public "float" of ACE's securities. • If ACE seeks stockholder approval of the Business Combination, its sponsor, officers and directors have agreed to vote in favor of such Business Combination, regardless of how its public stockholders vote. • The ability of ACE's public stockholders to exercise redemption rights with respect to a large number of its shares could increase the probability that the Business Combination would be unsuccessful. • ACE is not required to obtain an opinion from an independent investment banking firm or from an independent accounting firm, and consequently, its stockholders may have no assurance from an independent source that the price it is paying for the business is fair to ACE from a financial point of view. • Neither the ACE board of directors nor any committee thereof obtained a third party valuation in determining whether or not to pursue the Business Combination. • Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination. • ACE has identified a material weakness in its internal control over financial reporting as of December 31, 2020. If ACE is unable to develop and maintain an effective system of internal control over financial reporting, it may not be able to accurately report its financial results in a timely manner, which may adversely affect investor confidence in it and materially and adversely affect its business and operating results. • ACE has been subject to inquiries by the U.S. Securities and Exchange Commission {the "SEC") since May 2021 regarding certain disclosures in its Registration Statement on Form S - 4, filed with the SEC on February 10, 2021, as amended on March 19, 2021 , April 9, 2021 and May 6, 2021, and such inquiries remain ongoing. Such inquiries may materially adversely affect ACE or the combined company.

Risk Factors (continued) OCTOBER 2021 57 STRICTLY PRIVATE & CONFIDENTIAL RISKS RELATED TO THE BUSINESS COMBINATION AND ACE (CONTINUED) • Subsequent to consummation of the Business Combination , the combined company may be exposed to unknown or contingent liabilities and may be required to subsequently take write - downs or write - offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and its share price, which could cause you to lose some or all of your investment. • Future resales of common stock after the consummation of the Business Combination may cause the market price of the combined company's securities to drop significantly, even if its business is doing well. • The public stockholders of ACE will experience immediate dilution as a consequence of the issuance of common stock as consideration in the Business Combination and the private placement and due to future issuances pursuant to the combined company's equity plan(s). • The combined company may issue additional equity securities without your approval, which would dilute your ownership interests and may depress the market price of our securities. • The domestication of ACE as a Delaware corporation may result in adverse tax consequences for holders of ACE securities. • The Business Combination or combined company may be materially adversely affected by the recent COVID - 19 outbreak. • The price of the combined company's securities may be volatile. • Changes in laws or regulations, or a failure to comply with any laws or regulations , may adversely affect ACE's and the combined company's business , including ACE's ability to consummate the Business Combination, and ACE's and the combined company's results of operations.
