Forward-looking statements may be identified by the use of words such as "estimate," "plan," "project," "forecast," "intend," "expect," "anticipate," "believe," "seek," or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of management of Hyzon Motors Inc. ("Hyzon" or the "Company") and Decarbonization Plus Acquisition Corporation ("DCRB") 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 Hyzon and DCRB. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination between Hyzon and DCRB and related transactions (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 DCRB or Hyzon is not obtained; failure to realize the anticipated benefits of the Proposed Business Combination; risks relating to the uncertainty of the projected financial information with respect to Hyzon; risks related to the rollout of Hyzon's business and the timing of expected business milestones; the effects of competition on Hyzon's business; the amount of redemption requests made by DCRB's public stockholders; the ability of DCRB or the combined company to issue equity or equity-linked securities in connection with the Proposed Business Combination or in the future; and those factors discussed in DCRB's final prospectus filed with the Securities and Exchange Commission (the "SEC") on October 21, 2020 under the heading "Risk Factors" and other documents of DCRB filed, or to be filed, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither DCRB nor Hyzon presently know or that DCRB and Hyzon currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect DCRB's and Hyzon's expectations, plans or forecasts of future events and views as of the date of this Presentation. DCRB and Hyzon anticipate that subsequent events and developments will cause DCRB's and Hyzon's assessments to change. However, while DCRB and Hyzon may elect to update these forward-looking statements at some point in the future, DCRB and Hyzon specifically disclaim any obligation to do so.

Information regarding DCRB's directors and executive officers is available under the heading "Management" in DCRB's final prospectus filed with the SEC on October 21, 2020. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, will be contained in the proxy statement relating to the Proposed Business Combination when it becomes available. FINANCIAL INFORMATION; NON-GAAP FINANCIAL MEASURES The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X promulgated under the Securities Act of 1933, as amended. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement to be filed by DCRB with the SEC. Some of the financial information and data contained in this Presentation, such as EBITDA and EBITDA Margin, have not been prepared in accordance with United States generally accepted accounting principles ("GAAP"). DCRB and Hyzon believe that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to Hyzon's financial condition and results of operations. DCRB and Hyzon believe 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 Hyzon'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 Hyzon's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures.

FUTURE OF HYDROGEN IS NOW A hydrogen fuel cell truck has the potential to generate more revenue because it can carry more weight and can operate for 24 hours without the need for long recharging times ADVANTAGES OF HYDROGEN OVER BEV HYZON | DCRB+ Payload Hydrogen enables autonomy in high utilization, 24/7 assets with significant advantages over battery technology Hyzon has entered into a collaboration agreement to deploy the world's first fully autonomous, zero-emission truck currently targeted for 2021 Faster Refueling Better Range Environmentally cleaner Higher Payload The problem is that batteries are big and heavy. The more weight you're trying to move, the more batteries you need to power the vehicle. But the more batteries you use, the more weight you add-and the more power you need. Even with big breakthroughs in battery technology, electric vehicles will probably never be a practical solution for things like 18-wheelers, cargo ships, and passenger jets. Electricity works when you need to cover short distances, but we need a different solution for heavy, long-haul vehicles.

The 'hydrogen hub' method only adds an electrolyzer Depending on the electricity price, the hydrogen hub will switch between selling electricity to the grid or producing green hydrogen. Dispatch optimization is expected to maximize revenues and provide very low cost hydrogen Hydrogen is intended to only be produced with very low cost electricity and the hydrogen hub is expected to receive a 'tipping fee' for using waste gas. The only incremental expense to this model is a low-cost electrolyzer. This leads to hydrogen produced for $1 per kg at the hub or $2 per kg at the fueling station The hydrogen hub model is intended to be carbon negative with the carbon captured in briquettes In collaboration with its partners, Hyzon is currently building its first Hydrogen Hub in Australia. Hyzon's partner, NRG Global, has multiple waste to electricity sites, and is planning to build Hydrogen Hubs 48#49Distributed Steam Methane Reforming (SMR) Lowers the cost of hydrogen by eliminating the distribution costs Distributed SMR Hydrogen Landfill Animal waste Food waste Crop residue Wastewater treatment ■ ■ ■ Waste Gases ■ Renewable Natural Gas Natural Gas HYZON | DCRB+ Modular Distributed SMR Syngas CO2 Carbon Capture, Utilization and Storage Distributed SMR can use Renewable Natural Gas or Natural Gas as a feedstock.

The list below is qualified in its entirety by disclosures contained in future documents filed or furnished by the Company and Decarbonization Plus Acquisition Corporation ("Acquiror"), with the United States Securities and Exchange Commission ("SEC"), including the documents filed or furnished in connection with the proposed transactions between the Company and Acquiror. 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 Acquiror and the proposed transactions between the Company and Acquiror, and may differ significantly from and be more extensive than those presented below. The risks described below are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making an investment in the Company and Acquiror. Litigation and Regulatory Risks The motor vehicle manufacturing and hydrogen industries are highly regulated, and if we fail to comply with national, federal, state and local laws, rules, regulations and guidance, our business could be adversely affected. We are subject to licensing and operational requirements that result in substantial compliance costs, and our business would be adversely affected if our licenses are impaired. Litigation, regulatory actions and compliance issues could subject us to significant fines, penalties, judgments, remediation costs, negative publicity and requirements resulting in increased expenses. Laws, regulations and rules relating to privacy, information security, and data protection could increase our costs, affect or limit how we collect and use personal information, and adversely affect our business opportunities. In addition, the ongoing costs of complying with such laws, regulations and rules could be significant. Changes in government policy, including changes to existing trade agreements and any resulting changes in international trade relations, regulatory requirements and the availability of tax and other governmental incentives promoting fuel efficiency and alternate forms of energy, including the adoption of fuel cell technology may have an adverse effect on the Company. Changes in regulatory enforcement policies and priorities may negatively impact the management of our business, results of operations, and ability to compete. As a private company, we have not endeavored to establish and maintain public-company-quality internal control over financial reporting. If we fail to establish and maintain proper and effective internal control over financial reporting as a public company, 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. HYZON | DCRB+ 53#54■ APPENDIX Risk Factors (cont.) Relationship to Horizon; Intellectual Property There is no assurance that customers will embrace our product in significant numbers or that we will be able to identify potential new customers. Overall changes in consumer demand could have an adverse effect on our profitability and a mass market for our products may never develop or may take longer to develop than we anticipate. We may face legal challenges in one or more jurisdictions in our attempts to sell directly to customers that could adversely affect our costs. We are the U.S. subsidiary of Singapore incorporated Hymas Pte Ltd, which is majority but indirectly controlled by Horizon Fuel Cell Technologies Pte Ltd ("Horizon"). The Company was formed primarily to commercialize Horizon's industry-leading fuel cell technology for the manufacture and commercialization of certain vehicles for the transportation sector. Horizon has control over our voting stock, including the election of directors, and has a significant understanding of our business and may be uniquely positioned to compete against us. Certain customers of our existing deployed technology will continue to be customers of both the Company and Horizon, and certain future customers could terminate their relationships with us and/or become customers of Horizon. Although we have endeavored to enter into agreements on market terms, our agreements with Horizon and its affiliates may not reflect terms that would have resulted from arm's-length negotiations with unaffiliated third parties. Certain members of management, directors and shareholders will hold stock in both the combined company and Horizon and its affiliates and the Executive Chairman of the board of the combined company will also serve as the Chairman of the board of Horizon, and as a result may face actual or potential conflicts of interest. Horizon's subsidiaries will continue to be our majority shareholder immediately following the proposed transaction. We own certain pre-existing intellectual property jointly with Horizon's subsidiaries, and such intellectual property is subject to exclusive licenses between us and Horizon's subsidiaries. Such intellectual property may be more difficult to enforce, including if Horizon's subsidiaries refuse to join in our enforcement actions, or if our arrangements with Horizon's subsidiaries are considered unenforceable by courts or other government bodies. If such arrangements are considered unenforceable or otherwise impermissible, we may also be subject to fines, liability or other sanctions by courts or other government bodies. We may be unable to protect, defend, maintain or enforce intellectual property on which our business depends, including as against existing or future competitors. Failure to protect defend, maintain and enforce that intellectual property could result in our competitors offering similar products, potentially adversely affecting our growth and success. The provisional and non-provisional patent applications that we own may not issue as patents, which may hinder our ability to prevent competitors from selling products similar to ours. We may be subject to third-party claims of infringement, misappropriation or other violation of intellectual property rights, or other claims challenging our agreements related to intellectual property, which may be time-consuming and costly to defend, and could result in substantial liability. Business and Operating Risks; Projections Nonbinding pre-orders, signed memorandums of understanding or heads of terms in our sales pipeline may not be converted into binding orders or sales, and customers may cancel or delay that pipeline. The implementation of our business plan and strategy will require additional capital. If we are unable to achieve sufficient sales to generate that capital or otherwise raise capital, it may create substantial doubt about our ability to pursue our business objectives and achieve profitability or to continue as a going concern. If adequate capital is not available to us, including due to the cost and availability of funding in the capital markets, our business, operating results and financial condition may be harmed. There is no assurance that we will be able to execute on our business model, including market acceptance of our planned products or identify potential new customers. Our future growth is dependent upon the competition, pace and depth of hydrogen vehicle adoption generally and the willingness of potential customers, including operators of commercial vehicle fleets, to adopt hydrogen fuel cell technology and upon our ability to produce, sell and service vehicles that meet their needs. If the market for commercial hydrogen vehicles does not develop as we expect, or if it develops slower than we expect, or if there is inadequate access to refueling stations, our business, prospects, financial condition and operating results could be adversely affected. Our projections are subject to significant risks, assumptions, estimates and uncertainties. As a result, our projected revenues, market share, expenses and profitability may differ materially from our expectations. Incorrect estimates or assumptions by management in connection with the preparation of our consolidated financial statements could adversely affect our reported assets, liabilities, income, revenue or expenses. We expect to derive significant revenue from contracts awarded through competitive bidding processes involving substantial costs and risks. Due to this competitive pressure, we may be unable to realize revenue and achieve profitability. We may not be able to accurately estimate the supply and demand for our vehicles, which could result in a variety of inefficiencies in our business and hinder our ability to generate revenue. If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience delays. HYZON | DCRB*#55APPENDIX Risk Factors (cont.) Hydrogen Fuel Cell Industry; Automotive Industry Fuel cell and hydrogen production may not scale at the rate we anticipate, and there is no assurance that our expectation that the price of hydrocarbon will decrease and the hydrogen economy will become more competitive than the hydrocarbon economy will be realized. A significant energy transition away from oil derivatives may never occur or may be slow to occur. Our hydrogen vehicles compete for market share with vehicles powered by other vehicle technologies that may prove to be more attractive. If the prices of the alternative sources are lower than energy sources used by our products, offer greater efficiencies, greater reliability or otherwise benefit from other factors resulting in an overall lower total cost of ownership this could decrease incentives to transition to hydrogen vehicles adversely impact sales of our products and affect the commercial success of our vehicles or make our vehicles uncompetitive or obsolete. A significant percentage of our existing customers have access to secured hydrogen supplies. If hydrogen supplies do not scale as anticipated or new customers do not have access to hydrogen supplies, we may need to make significant capital expenditures in order to build out hydrogen infrastructure. If we are unable to provide customers with a complete hydrogen solution through strategic partnerships, including hydrogen plants and refueling stations, the results of our operations may be adversely impacted. Fuel prices, including volatility in the cost of diesel or a prolonged period of low gasoline and natural gas costs, could decrease incentives to transition to hydrogen vehicles, and low-carbon solutions may be more popular than decarbonization. Hydrogen is a flammable gas and therefore a potentially dangerous fuel. Any accidents involving our products or other hydrogen-based products, or safety concerns regarding the production, transportation and use of hydrogen generally, could materially impede our business and the widespread market acceptance and demand for fuel cell products. We operate in the highly competitive automotive industry and face aggressive and increasing competition to innovate and develop compelling renewable energy products. Many of our competitors and future competitors may have significantly more and if we do not compete effectively, our competitive positioning and our operating results will be harmed. Our operating success depends on our ability to hire and retain key personnel, including a highly skilled and diverse management team with experience in the fuel cell and automotive sectors. If any of our products are or are alleged to be defective in design or manufacturing or experience other failures, including with respect to the safety of hydrogen or the efficiency and performance of hydrogen fuel cells, we may be compelled to undertake product recalls or take other actions, which could adversely affect our business, prospects, operating results, reputation and financial condition. Insufficient warranty reserves to cover future warranty claims could adversely affect our business, prospects, financial condition and operating results. Our future growth depends upon our ability to maintain relationships with third parties, and the terms and enforceability of many of these relationships are not certain. We rely on our existing suppliers and source suppliers for critical components, and to complete building out our supply chain, while effectively managing the risks due to such relationships, which could result in increased supply costs. We will rely on complex machinery for our operations and production involves a significant degree of risk and uncertainty in terms of operational performance and costs. There are complex software and technology systems that need to be developed in coordination with vendors and suppliers in order to manufacture, market and distribute our hydrogen vehicles, and there can be no assurance such systems will be successfully developed. In addition, the development of these systems will require us to incur potentially significant costs and expenses. Our facilities could be damaged or adversely affected as a result of disasters or other unpredictable events. Any prolonged disruption in the operations of our facility would adversely affect our business, prospects, financial condition and operating results. We could be liable for environmental damages resulting from our manufacturing operations. Other Risks Cyber-attacks and other security breaches could have an adverse effect on our business, harm our reputation and expose us to liability. Sales of a substantial number of shares of our securities in the public market, including those issued upon exercise of Warrants, could cause the market price of our Class A common stock to drop significantly, even if our business is doing well. Changes in business, economic, or political conditions are beyond our control and could impact our business, resulting in lower revenues and other adverse effects to our results of operations. Our financial condition and results of operations are expected to be, adversely affected by the COVID-19 virus and related legislative and regulatory responses, which has caused a material adverse effect on the level of economic activity around the world, including in the markets we serve. Negative publicity could result in a decline in our growth and have a material adverse effect on our business, our brand and our results of operations. We operate in a cyclical industry. In an economic downturn, we may not be able to grow our business or maintain expected levels of liquidity, loss minimization and revenue growth. Our financial statements have not been audited or reviewed by an independent registered public accounting firm. The audited financial statements, which will be provided prior to the consummation of the proposed transactions between the Company and the Acquiror, may vary significantly from the financial condition and results of operations reflected in our historical unaudited financial statements. An audit of the Company could identify material weaknesses or significant deficiencies in our internal controls over financial reporting.
