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 the combined company’s 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 and raw materials. • Our gross profit and gross margin are dependent on a number of factors, including our services 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. • If demand for our services 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 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. M A R C H 2022 30 Risk Factors

Risks Relating to Tempo’s Business and Industry (continued) • Many of our customers and potential customers operate in industries that experience rapid technological change resulting in short product life cycles and as a result, if the product life cycles of our customers slow materially, and research and development expenditures are reduced, our financial condition, business and results of operations will be materially adversely affected. • We purchase a significant amount of the materials and components we use from a limited number of suppliers and if such 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. • 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, 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 or counterfeit products that we supply. • 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. • 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 cybersecurity breach or disruption in our 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 may not be accurate, and even if these markets 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. M A R C H 2022 31 Risk Factors (continued)

Risks Relating to Tempo’s Business and Industry (continued) • Our industry routinely experiences cyclical market patterns and our services 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 services and harm our operating results. • Third - party lawsuits and assertions to which may become subject alleging our infringement of patents, trade secrets or other intellectual property rights may have a significant adverse effect on our business and financial condition. • 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. • We conduct a portion of our business pursuant to U.S. government contracts, which are subject to unique risks. • The U.S. government may modify, curtail or terminate one or more of our contracts. • Any of the foregoing may adversely affect our margins, cash flow, and our ability to grow our revenue, and may increase the variability of our operating results from period to period. Our failure to meet our customers’ price expectations may adversely affect our business and results of operations. • We have identified material weaknesses in our internal control over financial reporting and may continue to identify additional material weaknesses in the future. If the combined company fails 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 the post - combination company. 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 Sponsor and ACE’s directors, officers and initial shareholders and their permitted transferees have agreed to vote in favor of the Business Combination, regardless of how ACE’s public shareholders vote. M A R C H 2022 32 Risk Factors (continued)

Risks Related to the Business Combination and ACE (continued) • 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. • 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. • Subsequent to consummation of the Business Combination, ACE 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 ACE’s financial condition, results of operations and share price, which could cause a loss of some or all of one’s investment. • The historical financial results of Tempo and unaudited pro forma financial information included in the Registration Statement may not be indicative of what Tempo’s actual financial position or results of operations would have been. • 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. • ACE may be forced to close the Business Combination even if they determined it is no longer in ACE’s shareholders’ best interest. • Since the Sponsor and ACE’s directors and executive officers have interests that are different, or in addition to (and which may conflict with), the interests of ACE’s shareholders, a conflict of interest may have existed in determining whether the Business Combination with Tempo is appropriate as ACE’s initial business combination. Such interests include that Sponsor will lose its entire investment in ACE if ACE’s business combination is not completed. • The exercise of ACE’s directors’ and executive officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in ACE’s shareholders’ best interest. • Deferred underwriting fees in connection with the IPO and payable at the consummation of the Business Combination will not be adjusted to account for redemptions by the public stockholders; if the public stockholders exercise their redemption rights, the amount of effective total underwriting commissions as a percentage of the aggregate proceeds from the IPO will increase. • 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. M A R C H 2022 33 Risk Factors (continued)

Risks Related to the Business Combination and ACE (continued) • 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 PIPE Investment and due to future issuances pursuant to the combined company’s equity plan(s). Having a minority share position may reduce the influence that current stockholders have on the management of the combined company. • Even if the Business Combination is consummated, the public warrants may never be in the money, and they may expire worthless and the terms of the warrants may be amended in a manner adverse to a holder if holders of at least 65% of the then outstanding public warrants approve of such amendment. • ACE may redeem unexpired warrants prior to their exercise at a time that is disadvantageous to an investor, thereby making those warrants worthless. • ACE’s and Tempo’s ability to consummate the Business Combination, and the operations of the combined company following the Business Combination, may be materially adversely affected by the COVID - 19 pandemic. • Following the consummation of the Business Combination, ACE’s only significant asset will be ACE’s ownership interest in the combined company and such ownership may not be sufficient to pay dividends or make distributions or loans to enable ACE to pay any dividends on the combined company’s common stock or satisfy ACE’s other financial conditions. • ACE has a specified maximum redemption threshold. This redemption threshold may make it more difficult for ACE to complete the Business Combination as contemplated. • The Sponsor may elect to purchase shares or warrants from public shareholders prior to the consummation of the Business Combination, which may influence the vote on the Business Combination and reduce the public “float” of ACE’s securities. • There are risks to ACE shareholders who are not affiliates of the Sponsor associated with becoming stockholders of the combined company through the Business Combination rather than acquiring securities of Tempo directly in an underwritten public offering, including no independent due diligence review by an underwriter and conflicts of interest of the Sponsor. • ACE is not registering the shares of the combined company common stock issuable upon exercise of the warrants under the Securities Act or any state securities laws at this time, and such registration may not be in place when an investor decides to exercise warrants, thus precluding such investor from being able to exercise its warrants and causing such warrants to expire worthless. • If third parties bring claims against ACE, the proceeds held in the trust account could be reduced and the per share redemption amount received by shareholders may be less than $10.00 per share (which was the offering price per unit in its initial public offering). M A R C H 2022 34 Risk Factors (continued)

Risks Related to the Business Combination and ACE (continued) • If, after ACE distributes the proceeds in the trust account to its public shareholders, ACE files a winding - up or bankruptcy petition or an involuntary winding - up or bankruptcy petition is filed against it that is not dismissed, a bankruptcy court may seek to recover such proceeds, and we and our board of directors may be exposed to claims of punitive damages. • If, before ACE distributes the proceeds in the trust account to its public shareholders, ACE files a winding - up or bankruptcy petition or an involuntary winding - up or bankruptcy petition is filed against it that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of ACE’s shareholders and the per share amount that would otherwise be received by ACE’s shareholders in connection with the liquidation may be reduced. • ACE’s shareholders may be held liable for claims by third parties against ACE to the extent of distributions received by them upon redemption of their shares. • Warrants will become exercisable for combined company common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to ACE stockholders. • Nasdaq may not list the combined company’s securities on its exchange, and the combined company may not be able to comply with the continued listing standards of Nasdaq, which could limit investors’ ability to make transactions in its securities and subject it to additional trading restrictions. Risks Related to the Convertible Notes • Our convertible notes to be issued and outstanding after the consummation of the Business Combination may impact our financial results, result in dilution to our stockholders, create downward pressure on the price of our common stock, and restrict our ability to raise additional capital or take advantage of future opportunities. • We may not have the ability to raise the funds necessary to settle conversions of the convertible notes, repurchase the convertible notes upon a fundamental change or repay the convertible notes in cash at their maturity, and our future debt may contain limitations on our ability to pay cash upon conversion, redemption or repurchase of the convertible notes. • We may still incur substantially more debt or take other actions that would diminish our ability to make payments on the convertible notes when due. • The Indenture will contain restrictions and limitations that could significantly impact our ability to operate our business. M A R C H 2022 35 Risk Factors (continued)

Risks Related to the Combined Company • Concentration of ownership among the combined company’s executive officers, directors and their affiliates may prevent new investors from influencing significant corporate decisions. • If the Business Combination’s benefits do not meet the expectations of investors or securities analysis, the market price of ACE’s securities or, following the Closing, the combined company’s securities, may decline. • Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud. Additional Risks Related to Ownership of the Combined Company Stock Following the Business Combination and the Combined Company operating as a Public Company • The price of the combined company’s stock and warrants may be volatile. • We do not intend to pay cash dividends for the foreseeable future. • Future resales of common stock after the consummation of the Business Combination may cause the market of the combined company’s securities to drop significantly, even if its business is doing well. • We will incur increased costs as a result of operating as a public company, and the combined company’s management will be required to devote substantial time to new compliance and investor relations initiatives. • 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 the combined company’s common stock may decline. • Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting changes or require us to change our compensation policies. M A R C H 2022 36 Risk Factors (continued)

Additional Risks Related to Ownership of the Combined Company Stock Following the Business Combination and the Combined Company operating as a Public Company (continued) • While we anticipate losing our emerging growth company status by the end of 2022 , we are currently an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and to the extent we have taken advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies . • The combined company’s 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 the combined company and its 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 the combined company’s stockholders’ ability to obtain a favorable judicial forum for disputes with the combined company or its directors, officers or employees. Risks Related to the Consummation of the Domestication of ACE (“the Domestication”) • The Domestication may result in adverse tax consequences for holders of ACE Class A ordinary shares and warrants. • Upon consummation of the Business Combination, the rights of holders of the combined company common stock arising under the DGCL as well as the proposed organizational documents will differ from and may be less favorable to the rights of holders of ACE Class A ordinary shares arising under the Cayman Islands Companies Act as well as ACE’s current amended and restated memorandum and articles of association. • Delaware law and the combined company’s proposed organizational documents contain certain provisions, including anti - takeover provisions that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable. Risks if the Adjournment Proposal (as defined in the Registration Statement) is not approved • If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination, our board of directors will not have the ability to adjourn the extraordinary general meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved, and, therefore, the Business Combination may not be consummated . M A R C H 2022 37 Risk Factors (continued)

Risks if the Domestication and the Business Combination are not Consummated • If we are not able to complete the Business Combination by July 13, 2022, and if ACE is not able to complete another business combination by then, in each case as may be further extended pursuant to the Cayman Constitutional Documents, ACE would cease all operations except for the purpose of winding up and ACE would redeem its Class A ordinary shares and liquidate the trust account, in which case ACE’s public shareholders may only receive approximately $10.00 per share and ACE’s warrants will expire worthless. • You will not have any rights or interests in funds from the trust account, except under certain limited circumstances. To liquidate your investment, therefore, you may be forced to sell your public shares and/or public warrants, potentially at a loss. • If ACE has not completed its initial business combination or validly extended beyond the combination deadline, its public shareholders may be forced to wait until after July 13, 2022 before redemption from the trust account. • 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 July 13, 2022 (or if such date is further extended at a duly called extraordinary general meeting, such later date) and ACE is unable to obtain additional capital, it 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. General Risk Factors • The combined company may be subject to securities litigation, which is expensive and could divert management attention. • If analysts do not publish research about our business or if they publish inaccurate or unfavorable research, the combined company’s stock price and trading volume could decline. • ACE’s warrants are accounted for as liabilities and the changes in value of its warrants could have a material effect on its financial results. • ACE identified a material weakness in its internal controls 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 ACE and materially and adversely affect its business and operating results. • ACE may face litigation and other risks as a result of the material weakness in its internal control over financial reporting. • ACE faces risks and uncertainties related to litigation, regulatory actions and government investigations and inquiries.
