CONFIDENTIAL © 2021 Jasper Therapeutics, Inc. Risk Factors 74 The list below of risk factors has been prepared solely for purposes of the proposed private placement transaction (the “Priv ate Placement”) as part of the proposed business combination (the “Business Combination”) of Amplitude Healthcare Acquisition Cor p. (“AMHC”) and Jasper Therapeutics, Inc. (“Jasper”), and solely for potential investors in the Private Placement, and not for any other purpose. T he risks presented below are certain of the general risks related to the businesses of Jasper, the Private Placement and the Bus ine ss 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 J asp er and AMHC, with the U.S. Securities and Exchange Commission (“SEC”), including the documents filed or furnished in connecti on with the proposed transactions between Jasper and AMHC. The risks presented in such filings will be consistent with those that would be required for a publ ic company in its SEC filings, including with respect to the business and securities of Jasper and AMHC and the proposed transac tio ns between Jasper and AMHC, 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 ri sk. Investors should carefully consider the risks and uncertainties inherent in an investment in Jasper and in the Securitie s, including those described below, before subscribing for the Securities. If either Jasper cannot address any of the following risks and uncertainties effectiv ely , or any other risks and difficulties that may arise in the future, Jasper’s business, financial condition or results of oper ati ons could be materially and adversely affected. The risks described below are not the only ones Jasper faces. Additional risks that Jasper currently does not kno w a bout or that Jasper currently believes to be immaterial may also impair its business, financial condition or results of opera tio ns. You should review the investors’ presentation and perform your own due diligence, prior to making an investment in AMHC or Jasper. Risks Related to Jasper’s Financial Position and Capital Requirements Jasper has incurred significant net losses since its inception. Jasper expects to incur net losses for the foreseeable future an d may never achieve or maintain profitability. Jasper will need substantial additional funding. If Jasper is unable to raise capital when needed, it would be forced to dela y, reduce or eliminate its research and product development programs or future commercialization efforts. Jasper has a limited operating history and no history of commercializing pharmaceutical products, which may make it difficult to evaluate the prospects for its future viability. Jasper has never generated revenue from product sales and may never be profitable. Risks Related to the Development of Jasper’s Product Candidates Jasper is early in its development efforts. If Jasper is unable to advance its product candidates to obtain regulatory approv al and ultimately commercialize its product candidates, or experiences significant delays in doing so, its business will be mate ria lly harmed. Results of preclinical studies and early clinical trials may not be predictive of results of future clinical trials, and such re sults do not guarantee approval of a product candidate by regulatory authorities. In addition, Jasper’s clinical trials to da te have been limited in scope and results received to date may not be replicated in expanded or additional future clinical trials. Clinical development involves a lengthy and expensive process, with an uncertain outcome. Jasper may incur additional costs o r e xperience delays in completing, or ultimately be unable to complete, the development and commercialization of any product can did ates. Jasper may not be successful in its efforts to identify, develop and commercialize additional product candidates. If these ef for ts are unsuccessful, Jasper may never become a commercial stage company or generate any revenues. Jasper may expend its limited resources to pursue a particular product candidate or indication and fail to capitalize on prod uct candidates or indications that may be more profitable or for which there is a greater likelihood of success. Jasper faces significant competition in an environment of rapid technological change, and there is a possibility that its com pet itors may achieve regulatory approval before Jasper or develop therapies that are safer or more advanced or effective than Ja spe r’s, which may harm Jasper’s financial condition and its ability to successfully market or commercialize its product candidates. If any of Jasper’s product candidates causes serious adverse events, undesirable side effects or unexpected characteristics, suc h events, side effects or characteristics could delay or prevent regulatory approval of the product candidate, limit its comm erc ial potential or result in significant negative consequences following any potential marketing approval.

CONFIDENTIAL © 2021 Jasper Therapeutics, Inc. Risk Factors (cont’d) 75 Risks Related to the Regulatory Regime for Jasper’s Product Candidates Jasper has no experience as a company in obtaining regulatory approval for a drug. The regulatory landscape that will govern Jasper’s product candidates is uncertain; regulations relating to more established cel lular therapy products are still developing, and changes in regulatory requirements could result in delays or discontinuation of development of its product candidates or unexpected costs in obtaining regulatory approval. The FDA and other governing bodies may disagree with Jasper’ s r egulatory plan and it may fail to obtain regulatory approval of its product candidates. Jasper’s product candidates are complex and difficult to manufacture. Jasper could experience delays in satisfying regulatory au thorities or production problems that result in delays in its development or commercialization programs, limit the supply of its product candidates, or otherwise harm its business. If clinical trials of Jasper’s product candidates it may identify and develop fail to demonstrate safety and efficacy to the sat isfaction of regulatory authorities or do not otherwise produce positive results, Jasper may incur additional costs or experi enc e delays in completing, or ultimately be unable to complete, the development and commercialization of such product candidates. Even if Jasper completes the necessary clinical trials, it cannot predict when, or if, it will obtain regulatory approval to com mercialize its product candidates in the United States or any other jurisdiction, and any such approval may be for a more nar row indication than Jasper seeks. Interim “top - line” and preliminary results from Jasper’s clinical trials that it may announce or publish from time to time may c hange as more patient data become available and are subject to audit and verification procedures that could result in materia l c hanges in the final data. If Jasper experiences delays or difficulties in the enrollment of patients in clinical trials, the cost of developing product ca ndidates could increase and its receipt of necessary regulatory approvals could be delayed or prevented. Jasper may never obtain FDA approval for any of its product candidates in the U.S., and even if it does, Jasper may never obt ain approval for or commercialize any of its product candidates in any other jurisdiction, which would limit Jasper’s ability to re alize their full market potential. Risks Related to Jasper’s Dependence on Third Parties Jasper relies on third parties to conduct its preclinical and clinical trials and will rely on them to perform other tasks fo r i t. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or comply with regu lat ory requirements, Jasper may not be able to obtain regulatory approval for or commercialize its product candidates and its business could be substantially harmed. Jasper is highly dependent on intellectual property licensed from third parties and termination of any of these licenses coul d r esult in the loss of significant rights, which would harm its business. Jasper currently relies on a single manufacturer for its clinical supply of its product candidates. In the event of a loss o f t his manufacturer, or a failure by such manufacturer to comply with FDA regulations, Jasper may not be able to find an alterna tiv e source on commercially reasonable terms, or at all. In addition, third - party manufacturers and any third - party collaborators may be unable to successfully scale - u p manufacturing of Jasper’s current or future product candidates in sufficient quality and quantity, which would delay or pre ven t Jasper from developing its product candidates and commercializing approved products, if any.

CONFIDENTIAL © 2021 Jasper Therapeutics, Inc. Risk Factors (cont’d) 76 Risks Related to Jasper’s Intellectual Property Jasper’s commercial success depends on its ability to obtain, maintain and protect its intellectual property and proprietary tec hnology. The patent protection Jasper obtains for its product candidates may not be sufficient enough to provide it with any competiti ve advantage or its patents may be challenged. Patent terms may be inadequate to protect Jasper’s competitive position on its product candidates for an adequate amount of t ime , and the lives of its patents may not be sufficient to effectively protect its product candidates and business. In addition, ch anges to patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing Jasper’s ability to p rot ect its product candidates. If Jasper is unable to protect the confidentiality of its trade secrets, its business and competitive position may be harmed. Third - party claims of intellectual property infringement, misappropriation or other violations may prevent or delay Jasper’s pro duct discovery and development efforts and have a material adverse effect on its business. Jasper may become involved in lawsuits to protect or enforce its patents or other intellectual property, which could be expen siv e, time - consuming and unsuccessful. Jasper may not be able to protect its intellectual property rights throughout the world. Other Risk Factors Related to Jasper The COVID - 19 pandemic has caused, and could continue to cause, severe disruptions in the U.S., regional and global economies and could seriously harm Jasper’s development efforts, increase its costs and expenses and have a material adverse effect on Jasp er ’s business, financial condition and results of operations. Jasper’s internal computer systems, or those of its third - party vendors, collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of its product development programs, compromise se nsitive information related to its business or prevent Jasper from accessing critical information, potentially exposing it to liability or otherwise adverse ly affecting its business. Jasper and its management have a limited track record as an operating company. Failures in the operational execution of the exp ected business plans may have a material impact on Jasper’s commercial prospects. Further, if Jasper is not able to attract and retain highly - qualified personnel, it may not be able to successfully implement its business strategy. If Jasper loses key management personnel, or if it fails to recruit additional highly skilled personnel, Jasper’s ability to con tinue developing and identify and develop new or next generation product candidates will be impaired, which could result in d ela ys in the development process, loss of market opportunities, make Jasper less competitive and have a material adverse effect on Jasper’s business, financial cond iti on and results of operations. Jasper may be adversely affected by existing or future laws and regulations. Jasper is subject to the laws and regulations of th e federal government and of various state, local and provincial government entities. These laws and regulations set very stri nge nt requirements for the business. In addition, such laws and regulations are subject to change and amendment at any time. Jasper may incur significant expenses re lated to compliance with such laws and regulations and it may need to adjust rapidly to address changes in the regulatory fra mew ork applicable to its business. Jasper may fail to comply with federal, state, local and international regulations in its area of operation, and fu tur e regulations may impose additional requirements on its business. Jasper’s business is subject to possible scrutiny from regu lat ors, who may enforce existing or future regulations that impact the viability or attractiveness of its assets. Jasper currently has limited marketing personnel. If Jasper is unable to establish effective marketing and sales capabilities or enter into agreements with third parties to market and sell its product candidates, if approved, Jasper may not be able to ef fe ctively market and sell its product candidates, if approved, or generate product revenues Jasper’s commercial success depends upon attaining significant market acceptance of its product candidates, if approved, amon g p hysicians, patients, healthcare payers and operators of major clinics. Jasper’s business will ultimately depend on its ability to successfully generate revenues from its product candidates, if app rov ed. Reimbursement for such products is subject to different regulatory regimes in different jurisdictions. If any of Jasper ’s product candidates is approved, an unfavorable reimbursement determination in any of the major markets could have a material impact on Jasper. Further, an unfa vor able change in such regimes (e.g., price controls) could have a material impact on Jasper.

CONFIDENTIAL © 2021 Jasper Therapeutics, Inc. Risk Factors (cont’d) 77 Risks Related to the Private Placement AMHC may be unable to raise sufficient capital in the Private Placement or otherwise obtain additional financing to complete the Business Combination or to fund the operations and growth of the combined company following the Business Combination (the “Co mb ined Company”). The issuance of shares of the Combined Company’s securities in connection with the Private Placement will dilute substantiall y t he voting power of Combined Company's stockholders. AMHC may issue shares of its Class A common stock upon the conversion of its Class B common stock at a ratio greater than one - to - one at the closing of the Business Combination as a result of the anti - dilution provisions contained in its amended and restate d certificate of incorporation. Any such issuance would dilute the interest of the Combined Company’s stockholders and likely present other ri sks . Risks Related to the Business Combination Each of AMHC and Jasper will incur significant transaction costs in connection with the Business Combination. The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied o r w aived, the Business Combination agreement may be terminated in accordance with its terms and the Business Combination may not be completed. The ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate the bu sin ess thereafter will be largely dependent upon the efforts of certain key personnel of Jasper. The loss of such key personnel co uld negatively impact the operations and financial results of the combined business.
