In evaluating the Proposals set forth in this proxy statement/prospectus, you should carefully read this proxy statement/prospectus, including the annexes, and especially consider the factors discussed in the section entitled “Risk Factors” beginning on page 37.

QUESTIONS AND ANSWERS

Q.   Why am I receiving this proxy statement/prospectus?

A.   You are receiving this proxy statement/prospectus in connection with the Shareholders Meeting. Tenzing is holding the Shareholders Meeting to consider and vote upon the Proposals described below. Your vote is important. You are encouraged to vote as soon as possible after carefully reviewing this proxy statement/prospectus.

Tenzing’s shareholders are being asked to consider and vote upon the Domestication Proposal to change the domicile of Tenzing by way of its continuation from the British Virgin Islands, as a business company incorporated under the laws of the British Virgin Islands to Delaware to become a corporation incorporated under the laws of the State of Delaware. The Domestication will be effected by Tenzing filing a Certificate of Corporate Domestication and the Interim Charter with the Delaware Secretary of State and filing an application to de-register with the Registrar of Companies of the British Virgin Islands and all outstanding securities of Tenzing will convert to outstanding securities of the Company, as described in more detail in this proxy statement/prospectus. The form of the proposed Interim Charter of the Company is attached to this proxy statement/prospectus as Annex A. See the section entitled “The Domestication Proposal.”

Tenzing’s shareholders are also being asked to consider and vote upon the Business Combination Proposal to approve the Merger Agreement and the Merger contemplated thereby. The Merger Agreement provides that, among other things, Tenzing’s wholly-owned subsidiary, Merger Sub, will merge with and into Reviva, with Reviva continuing as the surviving entity and becoming a subsidiary of the Company. Shareholder approval of the Merger Agreement and the transactions contemplated thereby is required by the Merger Agreement and the Memorandum and Articles of Association. A copy of the Merger Agreement is attached to this proxy statement/prospectus as Annex D and Tenzing encourages its shareholders to read it in its entirety. See the section entitled “The Business Combination Proposal.”

Tenzing’s shareholders are also being asked to consider and vote upon the 2020 Equity Incentive Plan Proposal to adopt the 2020 Equity Incentive Plan. Among other things, the 2020 Equity Incentive Plan, which would become effective upon the completion of the Business Combination, is intended to maintain and strengthen the Company’s ability to attract and retain key employees, directors, consultants and certain other individuals providing services to the Company and to motivate them to remain focused on long-term shareholder value. See the section entitled “The 2020 Equity Incentive Plan Proposal.” A copy of the 2020 Equity Incentive Plan is attached to this proxy statement/prospectus as Annex E, and Tenzing encourages its shareholders to read the plan in its entirety.

Tenzing’s shareholders are also being asked to consider and vote upon each of the Charter Amendment Proposals to approve and adopt the Amended and Restated Certificate of Incorporation and the Bylaws. See the section entitled “Proposal 4: The Charter Amendment Proposals” for a summary of the material provisions of and reasons for adoption of the Amended and Restated Certificate of Incorporation and the Bylaws. A copy of the Amended and Restated Certificate of Incorporation is attached to this proxy statement/prospectus as Annex B, and a copy of the Bylaws is attached to this proxy statement/prospectus as Annex C. Tenzing encourages its shareholders to read the Amended and Restated Certificate of Incorporation and the Bylaws in their entirety.

Tenzing’s shareholders are also being asked to consider and vote upon the Director Election Proposal to elect five directors to serve on the Company Board from the consummation of the Domestication and Business Combination becoming effective until the 2021 annual meeting of stockholders and until their respective successors are duly elected and qualified. It is noted in this regard that the appointments of the five directors under the Director Election Proposal will take effect under the terms of the Amended and Restated Certificate of Incorporation and the Bylaws of the Company as continued into Delaware. See the section entitled “The Director Election Proposal.”

Tenzing’s shareholders are also being asked to consider and vote upon the Working Capital Loan Conversion Proposal to permit the Sponsor to convert an additional $500,000 of promissory notes that were issued or are issuable to evidence working capital loans made by our Sponsor into additional Private Placement Units of the Company at a price of $10.00 per unit. See the section entitled “The Working Capital Loan Conversion Proposal.”

Tenzing’s shareholders are also being asked to consider and vote upon the Adjournment Proposal to adjourn the Shareholders Meeting to a later date or dates, including, if necessary, including to permit further solicitation and vote of proxies if it is determined by Tenzing that more time is necessary or appropriate to approve one or more Proposals at the Shareholders Meeting. See the section entitled “The Adjournment Proposal.”

The presence, in person or by proxy, of Tenzing shareholders representing a majority of the issued and outstanding ordinary shares on the Record Date and entitled to vote on the Proposals to be considered at the Shareholders Meeting will constitute a quorum for the Shareholders Meeting.

YOUR VOTE IS IMPORTANT. YOU ARE ENCOURAGED TO VOTE AS SOON AS POSSIBLE AFTER CAREFULLY REVIEWING THIS PROXY STATEMENT/PROSPECTUS.

Q:     What is being voted on at the Shareholders Meeting?

A:     At the Shareholders Meeting, the shareholders of Tenzing are being asked to vote on the following Proposals:

·        The Domestication Proposal;

·        The Business Combination Proposal;

·        The 2020 Equity Incentive Plan Proposal;

·        Each of the Charter Amendment Proposals;

·        Each of the nominees in the Director Election Proposal;

·        The Working Capital Loan Conversion Proposal; and

·        The Adjournment Proposal, if presented.

Q:   Are the Proposals conditioned on one another?

A:   Each of the Domestication Proposal, the Business Combination Proposal, the Director Election Proposal, each of the Charter Amendment Proposals and the 2020 Equity Incentive Plan Proposal is interdependent upon the others and each must be approved in order for Tenzing to complete the Business Combination contemplated by the Merger Agreement. All of the Proposals must be approved by the holders of a majority of the Tenzing Shares that are present and vote at the Shareholders Meeting.

Q.   Why is Tenzing proposing the Domestication?

A.   The Tenzing Board believes that it would be in the best interests of Tenzing to effect the Domestication to enable the Company to avoid certain taxes that would be imposed on the Company if the Company were to conduct an operating business in the United States as a foreign corporation following the Business Combination. In addition, the Tenzing Board believes Delaware provides a recognized body of corporate law that will facilitate corporate governance by the Company’s officers and directors. Delaware maintains a favorable legal and regulatory environment in which to operate. For many years, Delaware has followed a policy of encouraging companies to incorporate there and, in furtherance of that policy, has adopted comprehensive, modern and flexible corporate laws that are regularly updated and revised to meet changing business needs. As a result, many major corporations have initially chosen Delaware as their domicile or have subsequently reincorporated in Delaware in a manner similar to the procedures Tenzing is proposing. Due to Delaware’s longstanding policy of encouraging incorporation in that state and consequently its popularity as the state of incorporation, the Delaware courts have developed a considerable expertise in dealing with corporate issues and a substantial body of case law has developed construing the DGCL and establishing public policies with respect to Delaware corporations. It is anticipated that the DGCL will continue to be interpreted and explained in a number of significant court decisions that may provide greater predictability with respect to the Company’s corporate legal affairs. In connection with the Domestication, Tenzing will be filing the Interim Charter with the Secretary of State of Delaware prior to closing, which amends and removes the provisions of Tenzing’s Current Charter that terminate or otherwise become inapplicable because of the Domestications and provides Tenzing’s shareholders with the same or substantially the same rights in connection with the business combination; provided that the Interim Charter will also permit a majority of the Tenzing shareholders to act by written consent.

The Domestication will not occur unless the Tenzing shareholders have approved the Domestication Proposal, the Business Combination Proposal, the Charter Amendment Proposals, the Director Election Proposal and the Merger Agreement is in full force and effect prior to the Domestication.

Q.    What is involved with the Domestication?

A.   The Domestication will require Tenzing to file certain documents in both the British Virgin Islands and the State of Delaware. At the effective time of the Domestication, Tenzing will cease to be a company incorporated under the laws of the British Virgin Islands and in connection with the Business Combination, Tenzing will continue as a Delaware. The Current Charter will be replaced by the Interim Charter and your rights as a shareholder will cease to be governed by the laws of the British Virgin Islands and will be governed by Delaware law.

Q.    How will the Domestication affect my securities of Tenzing?

A.    Pursuant to the Domestication and without further action on the part of Tenzing’s shareholders, each outstanding ordinary share of Tenzing will convert to one outstanding share of the Company’s common stock and each outstanding warrant of Tenzing will convert to one outstanding warrant of the Company. Although it will not be necessary for you to exchange your certificates representing ordinary shares and warrants after the Domestication, the Company will, upon request, exchange your Tenzing share or warrant certificates for the applicable number of shares of Company’s common stock or warrants and all certificates for securities issued after the Domestication will be certificates representing securities of the Company.

Q:   What changes are being made to Tenzing’s Current Charter in connection with the business combination?

A:   In connection with the Domestication, Tenzing will be filing the Interim Charter with the Secretary of State of the State of Delaware prior to the Closing, which amends and removes the provisions of Tenzing’s Current Charter that terminate or otherwise become inapplicable because of the Domestication and provides Tenzing’s shareholders with the same or substantially the same rights in connection with the business combination. However, the Interim Charter will provide that Tenzing’s stockholders may act by written consent of the stockholders holding a majority of the issued and outstanding shares of Tenzing common stock, which is not permitted under the Current Charter. The Amended and Restated Charter, which will be effective as of the Closing and will provide for the following: (1) change the name of Tenzing to Reviva Pharmaceuticals Holdings, Inc., (2) remove or amend those provisions of our Interim Charter which terminate or otherwise cease to be applicable following the Closing, and (3) add new provisions to our Interim Charter which will be applicable following the Closing. For a summary of the differences between the Current Charter and Interim Charter and the Interim Charter and the Amended and Restated Charter, see the sections entitled “Proposal 1: The Domestication Proposal” and “Proposal 4: The Charter Amendment Proposals.”

Q.   What are the material U.S. federal income tax consequences of the Domestication to U.S. Holders of Tenzing Shares?

A.   The Domestication should qualify as a reorganization within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. However, due to the absence of guidance directly on how the provisions of Section 368(a) of the Code apply in the case of a statutory conversion of a corporation with no active business and only investment-type assets such as Tenzing, this result is subject to some uncertainty. If the Domestication qualifies as a reorganization within the meaning of Section 368(a), a U.S. Holder of Tenzing Shares will be subject to Section 367(b) of the Code and as a result:

·      A U.S. Holder of Tenzing Shares whose Tenzing Shares have a fair market value of less than $50,000 and who does not own actually and constructively 10% or more (by vote or value) of Tenzing on the date of the Domestication will not recognize any gain or loss and will not be required to include any part of Tenzing’s earnings in income;

·      A U.S. Holder of Tenzing Shares whose Tenzing Shares have a fair market value of $50,000 or more, but who on the date of the Domestication owns (actually and constructively) less than 10% of the total combined voting power or value of Tenzing will generally recognize gain (but not loss) on the exchange of Tenzing Shares for shares in the Company (a Delaware corporation) pursuant to the Domestication. As an alternative to recognizing gain, such U.S. Holders may file an election to include in income as a dividend the “all earnings and profits amounts,” (as defined in Treasury Regulation Section 1.367(b)-2(d)) attributable to their Tenzing Shares, provided certain other requirements are satisfied. Tenzing does not expect to have significant cumulative earnings and profits on the date of the Domestication; and

·      A U.S. Holder of Tenzing Shares whose Tenzing Shares have a fair market value of $50,000 or more, and who on the date of the Domestication owns (actually and constructively) 10% or more of the total combined voting power or value of Tenzing will generally be required to include in income as a dividend the “all earnings and profits amount,” (as defined in Treasury Regulation Section 1.367(b)-2(d))) attributable to its Tenzing Shares, provided certain other requirements are satisfied. Tenzing does not expect to have significant cumulative earnings and profits on the date of the Domestication.

Furthermore, even if the Domestication qualifies as a reorganization, the Domestication may be a taxable event to U.S. Holders of Tenzing Shares under special rules applicable to U.S. Holders who hold shares of a “passive foreign investment company,” or “PFIC” as described in “Proposal 1: The Domestication Proposal — Material U.S. Federal Income Tax Consequences of the Domestication to Tenzing Shareholders — U.S. Holders — PFIC Considerations.” Tenzing believes it has been treated as a PFIC since its inception. If the Domestication should fail to qualify as a reorganization under Section 368(a), a U.S. Holder of Tenzing Shares generally would recognize gain or loss with respect to its Tenzing Shares in an amount equal to the difference, if any, between the fair market value of the corresponding Company Common Stock received in the Domestication and the U.S. Holder’s adjusted tax basis in its Tenzing Shares surrendered. For a more complete discussion of the material U.S. federal income tax consequences of the Domestication, see the discussion in the section entitled “Proposal 1: The Domestication Proposal — Material U.S. Federal Income Tax Consequences of the Domestication to Tenzing Shareholders and Warrant Holders.”

Q.   What are the material U.S. federal income tax consequences to U.S. Holders that exercise their Redemption Rights?

A.   U.S. Holders that elect to exercise their Redemption Rights generally will recognize capital gain or loss equal to the difference between the amount of cash received on the Redemption of the Tenzing Shares and such U.S. Holder’s adjusted tax basis in such Tenzing Shares, which generally will be equal to the cost of such Tenzing Shares. A U.S. Holder who purchased Tenzing Shares in the IPO generally will have a tax basis in the Tenzing Shares that were part of the units equal to the portion of the purchase price of such units allocated to the Tenzing Shares (such allocation based on the relative fair market value of the Tenzing Shares and the Warrants at the time). However, in certain circumstances, the cash paid to such U.S. Holders will be treated as dividend income for U.S. federal income tax purposes. Moreover, because Tenzing should be considered a PFIC for U.S. federal income tax purposes, such U.S. Holders may be subjected to special rules applicable to PFICs as described in “The Domestication Proposal — Material U.S. Federal Income Tax Consequences of the Domestication to Tenzing Shareholders — U.S. Holders — PFIC Considerations.” For a more complete discussion of the material U.S. federal income tax consequences to U.S. Holders that elect to exercise their Redemption Rights, see the discussion in the section entitled “The Business Combination Proposal — Material U.S. Federal Income Tax Considerations to Shareholders Exercising Redemption Rights.”

Q.   Why is Tenzing proposing the Business Combination?

A.   Tenzing was organized to effect a merger, capital stock exchange, asset acquisition or other similar business combination with one or more businesses or entities. Since Tenzing’s organization, the Tenzing Board has sought to identify suitable candidates in order to effect such a transaction. In its review of Reviva, the Tenzing Board considered a variety of factors weighing positively and negatively in connection with the Business Combination. After careful consideration, the Tenzing Board has determined that the Business Combination presents a highly-attractive business combination opportunity. The Tenzing Board believes that, based on its review and consideration, the Business Combination with Reviva presents an opportunity to increase shareholder value. However, there can be no assurance that the anticipated benefits of the Business Combination will be achieved. Shareholder approval of the Business Combination is required by the Merger Agreement and the Memorandum and Articles of Association as well as to comply with Nasdaq Listing Rule 5635(a) and (d).

Q.   What will happen in the Business Combination?

A.   The Business Combination consists of a series of transactions pursuant to which (i) Tenzing will complete the Domestication and (ii) Merger Sub will following the Domestication, merge with and into Reviva with Reviva continuing as the surviving entity and a subsidiary of the Company. Upon the completion of the Domestication and the Merger, each issued and outstanding ordinary share of Tenzing will become a share of common stock of the Company, and each issued and outstanding warrant to purchase ordinary shares of Tenzing will become a warrant to purchase an equal number of shares of common stock of the Company.

Q.    What is the form of consideration that shareholders of Reviva will receive in return for the acquisition of Reviva by Tenzing?

Based on the assumptions set forth under the section entitled “Frequently Used Terms — Share Calculations and Ownership Percentages,” the total number of post-Merger shares of common stock issuable to the Reviva shareholders will be approximately 5,771,934, entitling such holders collectively to exchange Reviva securities for approximately 52.12% of the Company’s common stock in the aggregate.

Each share of Company Common Stock will provide the holder the rights to vote, receive dividends, and share in distributions in connection with a liquidation and other stockholder rights with respect to the Company.

Q.    How much consideration will the holders of securities of Reviva receive in connection with the acquisition of Reviva by Tenzing?

A.    In connection with the completion of the Merger, the holders of securities of Reviva will collectively receive as consideration for their existing Reviva Common Stock a number of successor securities with an aggregate value equal to (the “Merger Consideration”) (a) Sixty Two Million Four Hundred Thousand ($62,400,000), plus the additional contingent right to receive the Earnout Shares after the Closing; provided however that the Merger Consideration otherwise payable to Reviva stockholders is subject to the withholding of the Escrow Shares (as defined below) and is subject to reduction for indemnification obligations. The Merger Consideration to be paid to Reviva stockholders will be paid solely by the delivery of new shares of Tenzing common stock, each valued at the Redemption Price.

The Merger Consideration will be allocated among Reviva Common Stockholders” and Reviva Preferred Stockholders, such that Reviva Preferred Stockholders will receive $11,000,000 in Merger Consideration (pro rata amongst them based on the number of shares of Reviva preferred stock owned) before Reviva Common Stockholders receive any Merger Consideration, and then the Reviva Common Stockholders and Reviva Preferred Stockholders will receive the remaining $51.4 million of the Merger Consideration pro rata treating the Reviva preferred stock on an as-converted to common stock basis (which is currently on a one-for one basis); provided however that the Merger Consideration otherwise payable to Reviva stockholders is subject to the withholding of the Escrow Shares (as defined below) and is subject to reduction for indemnification obligations. The Merger Consideration is not subject to any purchase price adjustments. Certain convertible promissory notes of Reviva will be required to convert into shares of Reviva common stock prior to the Closing, and will share in the Merger Consideration, as will certain obligations owed by Reviva to a broker that will be paid with Reviva common stock prior to the Closing. However, the Merger Consideration does not include any value attributable to the Assumed Warrants and Assumed Options.

See the section entitled, “The Business Combination Proposal — The Merger Agreement — Merger Consideration.”

Q.    What equity stake will current Tenzing shareholders and Reviva shareholders hold in the Company immediately after the completion of the Business Combination?

A.    Upon the completion of the Business Combination (assuming, among other things, that no Tenzing shareholders exercise Redemption Rights with respect to their ordinary shares upon completion of the Business Combination and the other assumptions described under the section entitled “Frequently Used Terms — Share Calculations and Ownership Percentages”), the holders of securities of Reviva are expected to own approximately 52.12% of the Company’s outstanding common stock and the current holders of Tenzing Shares are expected to own approximately 47.88% of the Company’s outstanding common stock.

If any of Tenzing’s shareholders exercise their Redemption Rights, the percentage of the Company’s outstanding common stock held by the current holders of Tenzing Shares will decrease and the percentages of the Company’s outstanding common stock held by the holders of securities of Reviva will increase, in each case relative to the percentage held if none of the Tenzing Shares are redeemed.

All of the relative percentages above are for illustrative purposes only and are based upon certain assumptions as described in the section entitled “Frequently Used Terms — Share Calculations and Ownership Percentages.”

Should one or more of the assumptions prove incorrect, actual beneficial ownership percentages may vary materially from those described in this proxy statement/prospectus as anticipated, believed, estimated, expected or intended.

Q.    Did the Tenzing Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

A.    No. The Tenzing Board did not obtain a third-party valuation or fairness opinion in connection with its determination to approve the Business Combination. Tenzing’s officers and directors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of Tenzing’s advisors, enabled them to make the necessary analyses and determinations regarding the Business Combination. Accordingly, investors will be relying solely on the judgment of the Tenzing Board in valuing Reviva’s business and assuming the risk that the Tenzing Board may not have properly valued such business.

Q.    What happens to the funds deposited in the Trust Account after completion of the Business Combination?

A.    After completion of the Business Combination, the funds in the Trust Account will be used to pay holders of the Public Shares who exercise Redemption Rights and, after paying the Redemptions, a portion will be used to pay, as well as to pay transaction expenses incurred in connection with the Business Combination, including deferred IPO underwriting fees to Tenzing’s investment bankers and for working capital of the Company and its subsidiaries and general corporate purposes of the Company and its subsidiaries. Such funds may also be used to reduce the indebtedness and certain other liabilities of the Company and its subsidiaries. As of September 24, 2020, there were cash and marketable securities held in the Trust Account of approximately $34.4 million. These funds will not be released until the earlier of the completion of the Business Combination or the Redemption of the Public Shares if Tenzing is unable to complete a Business Combination by December 28, 2020 (except that interest earned on the amounts held in the Trust Account may be released earlier as necessary to pay for any franchise or income taxes and up to $50,000 in liquidation expenses).

Q.    What happens if a substantial number of Public Shareholders vote in favor of the Merger Proposal and exercise their Redemption Rights?

A.    Public Shareholders may vote in favor of the Business Combination and still exercise their Redemption Rights, provided that Tenzing (without regard to any assets or liabilities of Reviva) after payment of all such Redemptions, has at least $5,000,001 in net tangible assets immediately prior to the Closing. The Business Combination may be completed even though the funds available from the Trust Account and the number of Public Shareholders is substantially reduced as a result of Redemptions by Public Shareholders. If the Business Combination is completed notwithstanding Redemptions, the Company will have fewer Public Shares and Public Shareholders, the trading market for the Company’s securities may be less liquid and the Company may not be able to meet the minimum listing standards for a national securities exchange. Furthermore, the funds available from the Trust Account for working capital purposes of the Company after the Business Combination may not be sufficient for its future operations and may not allow the Company to reduce Reviva’s indebtedness and/or pursue its strategy for growth.

Q.    What conditions must be satisfied to complete the Business Combination?

A.    Unless waived by the parties to the Merger Agreement, and subject to applicable law, the consummation of the Business Combination is subject to a number of conditions set forth in the Merger Agreement including, among others, receipt of the requisite shareholder approvals contemplated by this proxy statement/prospectus. For a summary of the conditions that must be satisfied or waived prior to completion of the Business Combination, see the section entitled, “Proposal 2: The Business Combination Proposal—The Merger Agreement—Closing Conditions.”

Q.    When do you expect the Business Combination to be completed?

A.    It is currently expected that the Business Combination will be completed in November 2020. This timing depends, among other things, on the approval of the Proposals to be presented at the Shareholders Meeting. However, such meeting could be adjourned if the Adjournment Proposal is adopted at the Shareholders Meeting and Tenzing elects to adjourn the Shareholders Meeting to a later date or dates to permit further solicitation and vote of proxies if reasonably determined to be necessary or desirable by Tenzing.

Q.    Will Tenzing enter into any financing arrangements in connection with the Business Combination?

Q.    Why is Tenzing proposing the 2020 Equity Incentive Plan Proposal?

A.    The purpose of the 2020 Equity Incentive Plan is to enable the Company to offer eligible employees, directors and consultants cash and stock-based incentive awards in order to attract, retain and reward these individuals and strengthen the mutuality of interests between them and the Company’s stockholders. For more information, see the section entitled “The 2020 Equity Incentive Plan Proposal.”

Q.    Why is Tenzing proposing the Charter Amendment Proposals?

A.    Tenzing is proposing the Charter Amendment Proposals to (1) change the name of Tenzing to Reviva Pharmaceuticals Holdings, Inc., (2) remove those provisions of the Interim Charter which terminate or otherwise cease to be applicable following the closing of the Business Combination, and (3) adopt the Amended and Restated Certificate of Incorporation and Bylaws which will be applicable following the Domestication and the closing of the Business Combination. For a summary of the material provisions of and reasons for adoption of the Certificate of Incorporation and the Amended and Restated Bylaws, see the section entitled “Proposal 4: The Charter Amendment Proposals.”

Q.    Why is Tenzing proposing the Director Election Proposal?

Q.   Why is Tenzing proposing the Working Capital Loan Conversion Proposal?

Q.   Why is Tenzing proposing the Adjournment Proposal?

A.    Tenzing is proposing the Adjournment Proposal to allow the adjournment of the Shareholders Meeting to a later date or dates, including if necessary to permit further solicitation and vote of proxies if it is determined by Tenzing that more time is necessary or appropriate to approve one or more Proposals at the Shareholders Meeting.

Q.    When and where will the Shareholders Meeting be held?

A.    The Shareholders Meeting will be held at 9:00 a.m. Eastern Time on [●], 2020 at the offices of Ellenoff Grossman & Schole LLP, at 1345 Avenue of the Americas, 11^th Floor, New York, New York 10105. Only shareholders who held ordinary shares of Tenzing at the close of business on [●], 2020 will be entitled to attend and vote at the Shareholders Meeting and at any adjournments and postponements thereof.

Q.    Who is entitled to vote at the Shareholders Meeting?

A.    Tenzing has fixed [●], 2020 as the Record Date. If you were a shareholder of Tenzing at the close of business on the Record Date, you are entitled to vote on matters that come before the Shareholders Meeting. However, a shareholder may only vote his, her or its shares if he, she or it is present in person or is represented by proxy at the Shareholders Meeting.

Q.    How do I vote?

A.    If you are a record owner of your shares, there are two ways to vote your Tenzing Shares at the Shareholders Meeting:

You Can Vote By Signing and Returning the Enclosed Proxy Card.    If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares will be voted as recommended by the Tenzing Board “FOR” the Domestication Proposal, the Business Combination Proposal, the 2020 Equity Incentive Plan Proposal, each of the Charter Amendment Proposals, the election of each of the director nominees pursuant to the Director Election Proposal, the Working Capital Loan Conversion Proposal, and the Adjournment Proposal (if presented). Votes received after a matter has been voted upon at the Shareholders Meeting will not be counted.

You Can Attend the Shareholders Meeting and Vote in Person. When you arrive, you will receive a ballot that you may use to cast your vote.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. If you wish to attend the Shareholders Meeting and vote in person and your shares are held in “street name,” you must obtain a legal proxy from your broker, bank or nominee. That is the only way Tenzing can be sure that the broker, bank or nominee has not already voted your shares.

Q:    What if I do not vote my Tenzing Shares or if I abstain from voting?

A:    The approval of the Domestication Proposal, the Business Combination Proposal, the 2020 Equity Incentive Plan Proposal, the Charter Amendment Proposals, the Director Election Proposal, the Working Capital Loan Conversion Proposal, and the Adjournment Proposal, if presented, requires the affirmative vote of a majority of the outstanding Tenzing Shares as of the Record Date that are present and vote at the Shareholders Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast. As a result, if you abstain from voting on the Proposals, your Tenzing Shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of the Memorandum and Articles of Association), but will not be counted as votes cast.

Q:    What Proposals must be passed in order for the Business Combination to be completed?

A:    The Business Combination will not be completed unless the Domestication Proposal, the Business Combination Proposal, the 2020 Equity Incentive Plan Proposal, the Charter Amendment Proposals, and the Director Election Proposal, are approved. If Tenzing does not complete a business combination by December 28, 2020, Tenzing will be required to dissolve and liquidate itself and return the monies held within its Trust Account to its Public Shareholders unless Tenzing submits and its shareholders approve an extension.

Q:    How does the Tenzing Board recommend that I vote on the Proposals?

A:    The Tenzing Board unanimously recommends that the shareholders of Tenzing entitled to vote on the Proposals, vote as follows:

“FOR” approval of the Domestication Proposal;

“FOR” approval of the Business Combination Proposal;

“FOR” approval of the 2020 Equity Incentive Plan Proposal;

“FOR” approval of each of the Charter Amendment Proposals;

“FOR” approval of the election of each of the director nominees pursuant to the Director Election Proposal;

“FOR” approval of the Working Capital Loan Conversion Proposal; and

“FOR” approval of the Adjournment Proposal, if presented;

Q:    How many votes do I have?

A:    Tenzing shareholders have one vote per each ordinary share of Tenzing held by them on the Record Date for the Shareholders Meeting.

Q.    How will the Sponsor and Tenzing’s officers and directors vote in connection with the Proposals?

Q.    Do I have Redemption Rights with respect to my Tenzing Shares?

A.    Under Section 23.5 of the Memorandum and Articles of Association, prior to the completion of the Business Combination, Tenzing will provide all of the Public Shareholders with the opportunity to have their shares redeemed upon the completion of the Business Combination, subject to certain limitations, for cash equal to the applicable Redemption Price; provided, however, that Tenzing may not redeem such shares to the extent that such Redemption would result in Tenzing having net tangible assets (as determined under the Exchange Act) of less than $5,000,001 upon the completion of the Business Combination.

Public Shareholders may seek to have their shares redeemed regardless of whether they vote for or against the Business Combination, whether or not they were holders of Tenzing ordinary shares as of the Record Date or acquired their shares after the Record Date. The Redemptions will be effectuated in accordance with the Memorandum and Articles of Association and British Virgin Islands law. Any Public Shareholder who holds ordinary shares of Tenzing on or before [●], 2020 (two business days before the Shareholders Meeting) will have the right to demand that his, her or its shares be redeemed for a pro rata share of the aggregate amount then on deposit in the Trust Account, less any taxes then due but not yet paid, at the completion of the Business Combination); provided that such Public Shareholders follow the procedures provided for exercising such Redemption as set forth in the Memorandum and Articles of Association, as described below, by such date. However, the proceeds held in the Trust Account could be subject to claims that could take priority over those of Public Shareholders exercising Redemption Rights, regardless of whether such holders vote for or against the Business Combination Proposal and whether such holders are holders of Tenzing ordinary shares as of the Record Date. Therefore, the per-share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. A Public Shareholder will be entitled to receive cash for these shares only if the Business Combination is completed.

Q:    May the Sponsor, Tenzing’s directors, officers, advisors or their affiliates purchase shares in connection with the Business Combination?

A:    The Sponsor and Tenzing’s directors, officers, advisors or their affiliates may purchase Tenzing Shares in privately negotiated transactions or in the open market either prior to or after the Closing of the Business Combination, including from Tenzing shareholders who would have otherwise exercised their Redemption Rights. However, the Sponsor, directors and officers have no current commitments or plans to engage in such transactions and have not formulated any terms or conditions for any such transactions at the date of this proxy statement/prospectus. If Tenzing engages in such transactions, any such purchases will be subject to limitations regarding possession of any material nonpublic information not disclosed to the seller of such shares and they will not make any such purchases if such purchases are prohibited by Regulation M under the Exchange Act. Any such purchase after the Record Date would include a contractual acknowledgement that the selling shareholder, although still the record holder of Tenzing Shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its Redemption Rights. In the event the Sponsor or Tenzing’s directors, officers or advisors or their affiliates purchase shares in privately negotiated transactions from Public Shareholders who have already elected to exercise their Redemption Rights, such selling shareholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are in excess of the per-share pro rata portion of the aggregate amount then on deposit in the Trust Account.

Pursuant to the Insider Letter Agreement, the Sponsor and Tenzing’s directors and officers have agreed to waive their Redemption Rights with respect to the Founder Shares and Private Placement Shares owned by the Sponsor and any Public Shares purchased during or after the IPO in connection with the consummation of the Business Combination. However, if the Sponsor or Tenzing’s directors, officers and their affiliates acquired Public Shares in or after the IPO (or acquire Public Shares following the date of this proxy statement/prospectus), they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if Tenzing fails to complete a Business Combination by September 28, 2020.

Q.    Is there a limit on the number of shares I may redeem?

A.    Each Public Shareholder, together with any affiliate or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking Redemption Rights with respect to 20% or more of the Public Shares. Accordingly, any shares held by a Public Shareholder or “group” in excess of such 20% cap will not be redeemed by Tenzing. Any Public Shareholder who holds less than 20% of the Public Shares may have all of the Public Shares held by him or her redeemed for cash.

Q.    How do I exercise my Redemption Rights?

A.    If you are a Public Shareholder and you seek to have your shares redeemed, you must (i) demand, no later than 5:00 p.m., Eastern time on [●], 2020 (two (2) business days before the Shareholders Meeting), that Tenzing redeem your shares into cash; (ii) affirmatively certify in your request to Tenzing’s Transfer Agent for Redemption if you “ARE” or “ARE NOT” acting in concert or as a “group” (as defined in Section 13d-3 of the Exchange Act) and (iii) submit your request in writing to Tenzing’s Transfer Agent, at the address listed at the end of this section and deliver your shares to Tenzing’s Transfer Agent physically or electronically using The Depository Trust Company’s DWAC system at least two business days prior to the vote at the Shareholders Meeting.

Any request for Redemption, once made by a Public Shareholder, may be withdrawn at least two (2) business days before the vote is taken with respect to the Business Combination Proposal at the Shareholders Meeting. In addition, if you deliver your shares for Redemption to Tenzing’s Transfer Agent and later decide prior to the Shareholders Meeting not to elect Redemption, you may request that Tenzing’s Transfer Agent return the shares (physically or electronically). You may make such request by contacting Tenzing’s Transfer Agent at the phone number or address listed at the end of this section.

Any corrected or changed written demand of Redemption Rights must be received by Tenzing’s secretary two business days prior to the vote taken on the Business Combination Proposal at the Shareholders Meeting. No demand for Redemption will be honored unless the holder’s shares have been delivered (either physically or electronically) to the Transfer Agent at least two business days prior to the vote at the Shareholders Meeting.

Public Shareholders seeking to exercise their Redemption Rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from the Transfer Agent and time to effect delivery. It is Tenzing’s understanding that shareholders should generally allot at least two weeks to obtain physical certificates from the Transfer Agent. However, Tenzing does not have any control over this process and it may take longer than two weeks. Shareholders who hold their shares in street name will have to coordinate with their banks, brokers or other nominees to have the shares certificated or delivered electronically. There is a cost associated with this tendering process and the act of certificating the shares or delivering them through the DWAC system. The Transfer Agent will typically charge a nominal fee to the tendering broker and it would be up to the broker whether or not to pass this cost on to the redeeming shareholder. In the event the Business Combination is not completed, this may result in an additional cost to shareholders for the return of their shares.

If a Public Shareholder properly demands Redemption as described above, then, if the Business Combination is completed, Tenzing will redeem the shares subject to the Redemptions for cash. Such amount will be paid promptly after completion of the Business Combination. If you exercise your Redemption Rights, then you will be exchanging your Tenzing Shares for cash and will no longer own these shares following the Business Combination.

If you are a Public Shareholder and you exercise your Redemption Rights, it will not result in either the exercise or loss of any Tenzing warrants that you may hold. Your Tenzing warrants will continue to be outstanding following a Redemption of your Tenzing Shares and will become exercisable in connection with the completion of the Business Combination.

If you intend to seek Redemption of your Public Shares, you will need to deliver your shares (either physically or electronically) to Tenzing’s Transfer Agent prior to the Shareholders Meeting, as described in this proxy statement/prospectus. If you have questions regarding the certification of your position or delivery of your shares, please contact:

Q.    What happens if the Business Combination is not completed?

A.    If a Public Shareholder has tendered shares to be redeemed but the Business Combination is not completed, the Redemptions will be canceled and the tendered shares will be returned to the relevant Public Shareholders as appropriate. The current deadline set forth in the Memorandum and Articles of Association for Tenzing to complete its initial Business Combination is September 28, 2020.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

Tenzing is providing the following unaudited pro forma combined financial information to aid you in your analysis of the financial aspects of the Business Combination.

The unaudited pro forma combined balance sheet as of May 31, 2020 gives pro forma effect to the Business Combination as if it had been consummated as of that date. The unaudited pro forma combined statements of operations for the three months ended May 31, 2020 and for the year ended February 29, 2020 give pro forma effect to the Business Combination as if it had occurred as of the earliest period presented. This information should be read together with Reviva’s and Tenzing’s respective audited and unaudited financial statements and related notes, “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Reviva,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Tenzing” and other financial information included elsewhere in this proxy statement.

The unaudited pro forma combined balance sheet as of May 31, 2020 has been prepared using the following:

The unaudited pro forma combined statement of operations for the three months ended May 31, 2020 has been prepared using the following:

The unaudited pro forma combined statement of operations for the year ended February 29, 2020 has been prepared using the following:

Description of the Transactions

On July 20, 2020, Tenzing entered into the Merger Agreement. Pursuant to the Merger Agreement, subject to the terms and conditions set forth therein, (i) prior to the Closing, Tenzing will consummate the Domestication, and (ii) upon the Closing, Merger Sub will merge with and into Reviva, with Reviva continuing as the surviving corporation in the Merger and a wholly-owned subsidiary of Tenzing (after itsdomestication to Delaware).

The aggregate merger consideration to be paid pursuant to the Merger Agreement to Reviva shareholders will be an amount equal to the Merger Consideration, plus the additional contingent right to receive the Earnout Shares after the Closing, as described below. The Merger Consideration to be paid to Reviva stockholders will be paid solely by the delivery of new shares of the Company’s common stock, each valued at the Redemption Price.

In addition to the Merger Consideration set forth above, the Reviva Stockholders will also have a contingent right to receive the Earnout Shares after the Closing based on the stock price performance of the Company’s common stock and the achievement by Reviva of certain clinical trial milestones during the Earnout Period.

For more information about the Business Combination, please see the section entitled “Proposal 1: The Business Combination Proposal.” A copy of the Merger Agreement is attached to the accompanying proxy statement as Annex A.

Accounting for the Business Combination

The Business Combination will be accounted for as a reverse merger in accordance with U.S. GAAP. Under this method of accounting, Tenzing will be treated as the “acquired” company for financial reporting purposes. This determination was primarily based on the holders of Reviva expecting to have a majority of the voting power of the post-combination company, Reviva senior management comprising substantially all of the senior management of the post-combination company, the relative size of Reviva compared to Tenzing, and Reviva operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Reviva issuing stock for the net assets of Tenzing, accompanied by a recapitalization. The net assets of Tenzing will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of Reviva.

Basis of Pro Forma Presentation

The historical financial information has been adjusted to give pro forma effect to events that are related and/or directly attributable to the Business Combination, are factually supportable, and as it relates to the unaudited pro forma combined statement of operations, are expected to have a continuing impact on the results of the post-combination company. The adjustments presented on the unaudited pro forma combined financial statements have been identified and presented to provide relevant information necessary for an accurate understanding of the post-combination company upon consummation of the Business Combination.

The unaudited pro forma combined financial information is for illustrative purposes only. The financial results may have been different had the companies always been combined. You should not rely on the unaudited pro forma combined financial information as being indicative of the historical financial position and results that would have been achieved had the companies always been combined or the future financial position and results that the post-combination company will experience. Reviva and Tenzing have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

There is no historical activity with respect to Merger Sub, and accordingly, no adjustments were required with respect to this entity in the pro forma combined financial statements.

The unaudited pro forma combined financial information has been prepared assuming two alternative levels of redemption into cash of Tenzing ordinary shares:

Included in the shares outstanding and weighted average shares outstanding as presented in the pro forma combined financial statements are 5,771,934 shares of common stock to be issued to Reviva stockholders in connection with the Merger Agreement.

As a result of the Business Combination and immediately following the closing of the Business Combination, assuming no Tenzing shareholders elect to redeem their shares for cash, Reviva will own approximately 52.1% of the outstanding Company common stock and the former shareholders of Tenzing will own approximately 47.9% of the outstanding Company common stock, as of May 31, 2020 (in each case, not giving effect to any shares issuable to them upon the exercise of warrants).

If 2,002,460 ordinary shares are redeemed for cash, which assumes the maximum redemption of Tenzing ordinary shares providing for a minimum net tangible asset value of $5,000,001, after giving effect to payments to redeeming shareholders, Reviva will own approximately 63.6% of the outstanding Company common stock and Tenzing former shareholders will own approximately 36.4% of the outstanding Company common stock, as of May 31, 2020 (in each case, not giving effect to any shares issuable to them upon the exercise of warrants).

As the issuance of the additional 1,000,000 shares of common stock is contingent on the future performance of the trading price of the common stock and the achievement by Reviva of certain clinical trial milestones, they have been classified as an equity arrangement and therefore have not been recorded in the unaudited pro forma combined financial statements.

Pro Forma Adjustments to the Unaudited Combined Balance Sheet

Pro Forma Adjustments to the Unaudited Combined Statements of Operations

The following presents the calculation of basic and diluted weighted average ordinary shares outstanding. The computation of diluted loss per share excludes the effect of 6,861,313 warrants to purchase 6,861,313 shares of common stock, because the inclusion of these securities would be anti-dilutive.

COMPARATIVE SHARE INFORMATION

The following table sets forth the historical comparative share information for Reviva and Tenzing on a stand-alone basis and the unaudited pro forma combined per share information after giving effect to the Business Combination, (1) assuming no Tenzing shareholders exercise redemption rights with respect to their ordinary shares upon the consummation of the Business Combination; and (2) assuming that Tenzing shareholders exercise their redemption rights with respect to a maximum of 2,002,460 ordinary shares upon consummation of the Business Combination.

The historical information should be read in conjunction with the information in the sections entitled “Selected Historical Financial Information of Tenzing” and “Selected Historical Consolidated Financial and Other Data of Reviva” and the historical financial statements of Tenzing and Reviva  incorporated by reference in or included elsewhere in this proxy statement. The unaudited pro forma condensed combined per share information is derived from, and should be read in conjunction with, the information contained in the section of this proxy statement entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

The unaudited pro forma combined share information below does not purport to represent what the actual results of operations or the earnings per share would been had the companies been combined during the periods presented, nor to project the Company’s results of operations or earnings per share for any future date or period. The unaudited pro forma combined shareholders’ equity per share information below does not purport to represent what the value of Tenzing and Reviva would have been had the companies been combined during the periods presented.

RISK FACTORS

You should carefully consider all the following risk factors, together with all of the other information in this proxy statement/prospectus, including the financial information, before deciding how to vote or instruct your vote to be cast to approve the Proposals described in this proxy statement/prospectus.

The value of your investment following the completion of the Business Combination will be subject to significant risks affecting, among other things, the Company’s business, financial condition and results of operations. If any of the events described below occur, the Company’s post-Business Combination business and financial results could be adversely affected in material respects. This could result in a decline, which may be significant, in the trading price of the Company’s securities and you therefore may lose all or part of your investment. The risk factors described below are not necessarily exhaustive and you are encouraged to perform your own investigation with respect to the businesses of Tenzing and Reviva.

Throughout this section, references to the “Company” refer to the Company and its consolidated subsidiaries as the context so requires.

Risks Related to the Domestication and the Business Combination

Tenzing’s shareholders will experience dilution due to the issuance of Company Common Stock to the Reviva shareholders as consideration in the Merger entitling them to a significant voting stake in the Company.

Based on Reviva’s and Tenzing’s current capitalization (and the assumptions regarding the Merger Consideration paid at Closing described under the section entitled “Frequently Used Terms — Share Calculations and Ownership Percentages”), we anticipate issuing to the Reviva shareholders approximately an aggregate of 5,771,934 shares of Company Common Stock pursuant to the Merger Agreement, and it is currently expected that Tenzing’s current shareholders would hold in the aggregate approximately 47.88% of the outstanding common stock of the Company. If any of the Public Shares are redeemed in connection with the Merger, the percentage of the outstanding ordinary shares held by the Public Shareholders will decrease and the percentages of the outstanding common stock held immediately following the Business Combination by the Sponsor and outstanding common stock issuable to Reviva shareholders will increase. To the extent that any of the outstanding warrants and Assumed Options are exercised for Company Common Stock, or additional awards are issued under the proposed 2020 Equity Incentive Plan, Tenzing’s existing shareholders may experience substantial dilution. Such dilution could, among other things, limit the ability of Tenzing’s current shareholders to influence the Company’s management through the election of directors following the Business Combination.

The ability of Tenzing’s shareholders to exercise Redemption Rights with respect to the Public Shares may prevent Tenzing from completing the Business Combination or optimizing its capital structure.

Tenzing does not know how many shareholders will ultimately exercise their Redemption Rights in connection with the Business Combination. As such, the Business Combination is structured based on Tenzing’s expectations (and those of the other parties to the Merger Agreement) as to the number of shares that will be submitted for Redemption. In addition, if a larger number of shares are submitted for Redemption than Tenzing initially expected, Tenzing may need to seek to arrange for additional third party financing to be able to have the minimum amount of cash required pursuant to the Merger Agreement.

Furthermore, raising such additional financing may involve dilutive equity issuances at higher than desirable levels. For information on the consequences if the Business Combination is not completed or must be restructured, please see the section of this proxy statement/prospectus entitled “Risk Factors — Risks Related to Tenzing.”

Subsequent to the completion of the Business Combination, the Company may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition and its share price, which could cause you to lose some or all of your investment.

Tenzing cannot assure you that the due diligence Tenzing has conducted on Reviva will reveal all material issues that may be present with regard to Reviva, or that factors outside of Tenzing’s or Reviva’s control will not later arise. As a result of unidentified issues or factors outside of Tenzing’s or Reviva’s control, the Company may be forced to later write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in reporting losses. Even if Tenzing’s due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with the preliminary risk analysis conducted by Tenzing. Even though these charges may be non-cash items that would not have an immediate impact on the Company’s liquidity, the fact that the Company reports charges of this nature could contribute to negative market perceptions about the Company or its securities. In addition, charges of this nature may cause the Company to violate leverage or other covenants to which it may be subject. Accordingly, any shareholders who choose to remain shareholders following the Business Combination could suffer a reduction in the value of their shares from any such write-down or write-downs.

The Company’s ability to be successful following the Business Combination will depend upon the efforts of the Company Board and Reviva’s key personnel and the loss of such persons could negatively impact the operations and profitability of the Company’s business following the Business Combination.

The Company’s ability to be successful following the Business Combination will be dependent upon the efforts of the Company Board and key personnel. Tenzing cannot assure you that, following the Business Combination, the Company Board and the Company’s key personnel will be effective or successful or remain with the Company. In addition to the other challenges they will face, such individuals may be unfamiliar with the requirements of operating a public company, which could cause the Company’s management to expend time and resources becoming familiar with such requirements.

The COVID-19 pandemic triggered an economic crisis which may delay or prevent the consummation of the Business Combination.

In December 2019, a coronavirus (COVID-19) outbreak was reported in China, and, in March 2020, the World Health Organization declared it a pandemic. Since being initially reported in China, the coronavirus has spread throughout the world and has resulted in unprecedented restrictions and limitations on operations of many businesses, educational institutions and governmental entities, including in the United States and Canada. Given the ongoing and dynamic nature of the COVID-19 crisis, it is difficult to predict the impact on the business of Reviva, Tenzing and Reviva Pharmaceutical Holdings, Inc., and there is no guarantee that efforts by Reviva, Tenzing and Reviva Pharmaceutical Holdings, Inc. to address the adverse impact of COVID-19 will be effective. If Reviva or Tenzing is unable to recover from a business disruption on a timely basis, the Business Combination and Reviva Pharmaceutical Holdings, Inc.’s business and financial conditions and results of operations following the completion of the Business Combination would be adversely affected. The Business Combination may also be delayed and adversely affected by the coronavirus outbreak and become more costly. Each of Reviva and Tenzing may also incur additional costs to remedy damages caused by such disruptions, which could adversely affect its financial condition and results of operations.

The Company will be a holding company and its only material asset after completion of the Business Combination will be its interest in Reviva, and it is accordingly dependent upon distributions made by its subsidiaries to pay taxes and pay dividends.

Upon completion of the Business Combination, the Company will be a holding company with no material assets other than cash in the approximate amount of approximately $8.6 million assuming maximum redemption or approximately $29.9 million if no redemption and its ownership of all of the issued and outstanding Reviva Common Stock. As a result, the Company will have no independent means of generating revenue or cash flow. The Company’s ability to pay taxes and pay dividends will depend on the financial results and cash flows of Reviva and its subsidiaries and the distributions it receives from Reviva. Deterioration in the financial condition, earnings or cash flow of Reviva and its subsidiary for any reason could limit or impair Reviva’s ability to pay such distributions. Additionally, to the extent that the Company needs funds and Reviva and/or its subsidiary are restricted from making such distributions under applicable law or regulation or under the terms of any financing arrangements, or Reviva is otherwise unable to provide such funds, it could materially adversely affect the Company’s liquidity and financial condition.

Dividends on the Company’s common stock, if any, will be paid at the discretion of the Company Board, which will consider, among other things, the Company’s business, operating results, financial condition, current and expected cash needs, plans for expansion and any legal or contractual limitations on its ability to pay such dividends. Financing arrangements may include restrictive covenants that restrict the Company’s ability to pay dividends or make other distributions to its stockholders. In addition, Reviva is generally prohibited under Delaware law from making a distribution to a shareholder to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Reviva (with certain exceptions) exceed the fair value of its assets. Reviva’s subsidiaries are generally subject to similar legal limitations on their ability to make distributions to Reviva. If Reviva does not have sufficient funds to make distributions, the Company’s ability to declare and pay cash dividends may also be restricted or impaired.

Some of Tenzing’s officers and directors may be argued to have conflicts of interest that may influence or have influenced them to support or approve the Business Combination without regard to your interests or in determining whether Reviva is appropriate for Tenzing’s initial business combination.

The personal and financial interests of Tenzing’s Sponsor, officers and directors may influence or have influenced their motivation in identifying and selecting a target for the Business Combination, their support for completing the Business Combination and the operation of the Company following the Business Combination.

Tenzing’s Sponsor owns 1,581,250 ordinary shares, which were initially acquired prior to Tenzing’s IPO and for an aggregate purchase price of $25,000 and Tenzing’s directors and officers have pecuniary interests in such ordinary shares through their ownership interest in the Sponsor. In addition, the Sponsor purchased an aggregate of 323,750 Private Placement Units at a price of $10 per unit. Such shares had an aggregate market value of approximately $20.6 million based on the last sale price of $10.75 per share on Nasdaq on October 1, 2020. Tenzing’s Memorandum and Articles of Association require Tenzing to complete an initial business combination prior December 28, 2020 (unless Tenzing submits and its shareholders approve an extension of such date). If the Business Combination is not consummated and Tenzing is forced to wind up, dissolve and liquidate in accordance with Tenzing’s Memorandum and Articles of Association, the securities of Tenzing currently held by the Sponsor will be worthless as the holders have waived liquidation rights with respect to such securities.

Certain officers and directors of Tenzing also participate in arrangements that may be argued to provide them with other interests in the Business Combination that are different from yours, including, among others, arrangements for the continued service as directors of the Company. Tenzing’s officers and directors collectively (including entities controlled by and families of officers and directors)  have made an aggregate average investment per share of $1.78 (including the Founder Shares and Private Placement Shares allotted as part of Private Placement Units; excluding the Private Placement Warrants) as of the consummation of Tenzing’s initial public offering, exclusive of their aggregate working capital contributions of ($1,775,000) as of September 25, 2020.  If such working capital contributions are included, Tenzing’s officers and directors collectively have made an aggregate average investment per share of $2.47 (including Founder Shares and Private Placement Shares allotted as part of Private Placement Units; excluding Private Placement Warrants allotted as part of Private Placement Units) as of September 25, 2020 (assuming $1,775,000 of working capital units convert to units at $10.00 per share). The officers’ and directors’ significantly lower investment per share in their ordinary shares of Tenzing results in a difference between a transaction that increases the value of the officers' and directors' investment and a transaction that increases the value of the public shareholders' investment.  As such, Tenzing's officers’ and directors’ risk to lose their entire investment if the Business Combination is not approved may be argued to create a conflict of interest that may cause them to support or approve the Business Combination.

Further, Tenzing’s Sponsor, officers and directors have, pursuant to the Insider Letter Agreement, each agreed (A) to vote any Tenzing shares owned by them in favor of the Business Combination and (B) not to redeem any shares in connection with a shareholder vote to approve the Business Combination.

These interests, among others, may influence or have influenced the Sponsor and the officers and directors of Tenzing and Reviva to support or approve the Business Combination. For more information concerning the interests of Tenzing’s officers and directors, see the section entitled “The Business Combination Proposal — Interests of Tenzing’s Directors and Officers and Others in the Business Combination” and the risk factor entitled “ — Risks Related to Tenzing — The Sponsor controls a substantial interest in Tenzing and thus may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support” in this proxy statement/prospectus.

Tenzing has not obtained an opinion from an independent investment banking firm or another independent firm, and consequently, you may have no assurance from an independent source that the terms of the Business Combination are fair to Tenzing from a financial point of view.

The Tenzing Board did not obtain a third-party valuation or fairness opinion in connection with their determination to approve the Business Combination. Tenzing is not required to obtain an opinion from an independent investment banking firm that is a member of FINRA or from another independent firm that the price it is paying is fair to Tenzing from a financial point of view. In analyzing the Business Combination, the Tenzing Board and Tenzing’s management conducted due diligence on Reviva and researched the industry in which Reviva operates and concluded that the Business Combination was in the best interest of its shareholders. Accordingly, Tenzing’s shareholders will be relying solely on the judgment of the Tenzing Board in determining the value of the Business Combination, and the Tenzing Board may not have properly valued such business. The lack of third-party valuation or fairness opinion may also lead an increased number of shareholders to vote against the Business Combination or demand Redemption of their shares, which could potentially impact our ability to consummate the Business Combination. For more information about our decision-making process, see the section entitled “The Business Combination Proposal — Tenzing Board’s Reasons for the Approval of the Business Combination.”

Tenzing does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible to complete a Business Combination in which a substantial majority of Tenzing’s shareholders do not intend to retain their investment in which case the Reviva shareholders may receive a greater number of post-Business Combination Company Common Stock as a result of redemptions.

The Memorandum and Articles of Association of Tenzing does not provide a specified maximum Redemption threshold, except that in no event will Tenzing redeem its Public Shares in an amount that would cause its net tangible assets, without regard to any assets or liabilities of Reviva, to be less than $5,000,001 immediately prior to the completion of the Business Combination (such that Tenzing is not subject to the SEC’s “penny stock” rules) or any greater net tangible asset or cash requirement contained in the Merger Agreement. As a result, Tenzing may be able to consummate the Business Combination even if a substantial majority of the Public Shareholders do not agree with the transaction and have redeemed their shares or if we have entered into privately negotiated agreements for investors to sell their shares to the Sponsor, officers, directors, advisors or their affiliates. In the event the aggregate cash consideration we would be required to pay for all Public Shares that are validly submitted for Redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed Business Combination exceed the aggregate amount of cash available to Tenzing, Tenzing will not consummate the Business Combination or redeem any shares, all Public Shares submitted for redemption will be returned to the holders thereof and Tenzing will be required to liquidate.

Nasdaq may delist the Company’s securities from trading on its exchange, which could limit investors’ ability to make transactions in the Company’s securities and subject the Company to additional trading restrictions.

Tenzing’s securities are currently listed on Nasdaq and it is anticipated that, following the Business Combination, the Company’s securities will continue to be listed on Nasdaq. However, there can be no assurance that the Company’s securities will continue to be listed on Nasdaq in the future. In order to continue to maintain the listing of the Company’s securities on Nasdaq, the Company must maintain certain financial, distribution, liquidity and stock price levels. For instance, the Company’s stock price would generally be required to be at least $4 per share and its stockholders’ equity would generally be required to be at least $5 million and the Company would be required to have a minimum of 300 public holders of “round lots” of 100 shares (with at least 50% of such round lot holders holding securities with a market value of at least $2,500). In addition to the listing requirements for the Company’s common stock, Nasdaq imposes listing standards on warrants. There can be no assurance that the Company will be able to meet those initial listing requirements.

If Nasdaq delists the Company’s securities from trading on its exchange and the Company is not able to list its securities on another national securities exchange, Tenzing expects the Company’s securities could be quoted on an over-the-counter market. If this were to occur, the Company could face significant material adverse consequences, including:

•        a limited availability of market quotations for its securities;

•        reduced liquidity for its securities;

•        a determination that the Company common stock is a “penny stock” which will require brokers trading in the common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for the Company’s securities;

•        a limited amount of news and analyst coverage; and

•        a decreased ability to issue additional securities or obtain additional financing in the future.

With respect to Tenzing ordinary shares before the Business Combination, if these shares are delisted from trading by Nasdaq, then such an event may be considered a Material Adverse Event under the Merger Agreement, and Reviva is not obligated to close the Business Combination for as long as such Material Adverse Event is continuing and uncured.

The unaudited pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” may not be representative of the Company’s results if the Business Combination is completed.

Tenzing and Reviva currently operate as separate companies and have had no prior history as a combined entity, and their operations have not previously been managed on a combined basis. The pro forma financial information included in this proxy statement/prospectus is presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Business Combination been completed at or as of the dates indicated, nor is it indicative of the future operating results or financial position of the Company. The pro forma statement of operations does not reflect future nonrecurring charges resulting from the Business Combination. The unaudited pro forma financial information does not reflect future events that may occur after the Business Combination and does not consider potential impacts of future market conditions on revenues or expenses. The pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” has been derived from Tenzing’s and Reviva’s historical financial statements and certain adjustments and assumptions have been made regarding the Company after giving effect to the Business Combination. There may be differences between preliminary estimates in the pro forma financial information and the final acquisition accounting, which could result in material differences from the pro forma information presented in this proxy statement/prospectus in respect of the estimated financial position and results of operations of the Company.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate and other factors may affect the Company’s financial condition or results of operations following the Closing. Any potential decline in the Company’s financial condition or results of operations may cause significant variations in the stock price of the Company.

During the pendency of the Business Combination, Tenzing will not be able to enter into a business combination with another party because of restrictions in the Merger Agreement. Furthermore, certain provisions of the Merger Agreement will discourage third parties from submitting alternative takeover proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.

Covenants in the Merger Agreement impede the ability of Tenzing to make acquisitions or complete other transactions that are not in the ordinary course of business pending completion of the Business Combination. As a result, Tenzing may be at a disadvantage to its competitors during that period. In addition, while the Merger Agreement is in effect, neither Tenzing nor Reviva may solicit, assist, facilitate the making, submission or announcement of, or intentionally encourage any alternative acquisition proposal, such as a merger, material sale of assets or equity interests or other business combination, with any third party, even though any such alternative acquisition could be favorable to Tenzing’s shareholders than the Business Combination. In addition, if the Business Combination is not completed, these provisions will make it more difficult to complete an alternative business combination following the termination of the Merger Agreement due to the passage of time during which these provisions have remained in effect.

If the conditions to the Merger Agreement are not met, the Business Combination may not occur.

Even if the Merger Agreement is approved by the shareholders of Tenzing and Reviva, specified conditions must be satisfied or waived before the parties to the Merger Agreement are obligated to complete the Business Combination. For a list of the material closing conditions contained in the Merger Agreement, see the section entitled “The Business Combination Proposal — The Merger Agreement — Closing Conditions.” Tenzing and Reviva may not satisfy all of the closing conditions in the Merger Agreement. If the closing conditions are not satisfied or waived, the Business Combination will not occur, or will be delayed pending later satisfaction or waiver, and such delay may cause Tenzing and Reviva to each lose some or all of the intended benefits of the Business Combination.

Each of Tenzing and Reviva may waive one or more of the conditions to the Business Combination.

Each of Tenzing and Reviva may agree to waive, in whole or in part, some of the conditions to their respective obligations to complete the Business Combination, to the extent permitted by their respective existing charters and applicable laws. For example, it is a condition to Tenzing’s obligations to close the Business Combination that the representations and warranties of Reviva and its subsidiaries are true and correct in all respects as of the date of the Merger Agreement and as of the date of the Closing Date (as defined in the Merger Agreement) (or an earlier date to the extent that an earlier date is referenced in the representation and warranty), except, for certain of the representations and warranties, for such inaccuracies that, individually or in the aggregate, would not result in a Material Adverse Effect (as defined in the Merger Agreement) on Reviva and its subsidiaries. Tenzing is not able to waive the condition that its stockholders approve the Business Combination. Reviva is not able to waive the condition that its stockholders approve the Business Combination. The following closing conditions also may not be waived: expiration of any applicable waiting period under any antitrust laws; receipt of requisite consents from governmental authorities to consummate the Transactions; the absence of any law or order that would prohibit the consummation of the Merger or other transactions contemplated by the Merger Agreement; upon the Closing, after giving effect to the completion of the Redemption, the Company having net tangible assets of at least $5,000,001; and the effectiveness of this registration statement. If either Tenzing or Reviva elects to waive any conditions to their respective obligations to complete the Business Combination, the parties may close the Business Combination without the satisfaction of any such conditions.

Because Tenzing is incorporated under the laws of the British Virgin Islands, in the event the Business Combination is not completed, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. Federal courts may be limited.

Because Tenzing is currently incorporated under the laws of the British Virgin Islands, you may face difficulties in protecting your interests and your ability to protect your rights through the U.S. Federal courts may be limited prior to the Domestication. Tenzing is currently a business company under the laws of the British Virgin Islands. As a result, it may be difficult for investors to effect service of process within the United States upon Tenzing’s directors or officers, or enforce judgments obtained in the United States courts against Tenzing’s directors or officers.

Until the Domestication is effected, Tenzing’s corporate affairs are governed by the Memorandum and Articles of Association, the Companies Act and the common law of the British Virgin Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of its directors to Tenzing under the laws of the British Virgin Islands in part governed by the common law of the British Virgin Islands. The common law of the British Virgin Islands is derived in part from comparatively limited judicial precedent in the British Virgin Islands as well as from English common law, the decisions of whose courts are of persuasive authority, but are not binding on a court in the British Virgin Islands. The rights of Tenzing’s shareholders and the fiduciary responsibilities of its directors under British Virgin Islands law are different from what they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the British Virgin Islands has a different body of securities laws as compared to the United States, and certain states, such as Delaware, may have more fully developed and judicially interpreted bodies of corporate law. In addition, British Virgin Islands companies may not have standing to initiate a shareholders derivative action in a Federal court of the United States.

Tenzing has been advised by its British Virgin Islands legal counsel that the courts of the British Virgin Islands are unlikely (i) to recognize or enforce against Tenzing judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the British Virgin Islands, to impose liabilities against Tenzing predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the British Virgin Islands of judgments obtained in the United States, the courts of the British Virgin Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the British Virgin Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a British Virgin Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the British Virgin Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A British Virgin Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

The Public Shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the Tenzing Board or controlling shareholders than they would as public shareholders of a United States company.

There is a risk that a U.S. Holder may recognize taxable gain with respect to its Tenzing Shares at the effective time of the Domestication.

The Tenzing Board believes the Domestication should qualify as a reorganization within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. However, due to the absence of guidance directly on how the provisions of Section 368(a) of the Code apply in the case of a statutory conversion of a corporation with no active business and only investment-type assets such as Tenzing, this result is subject to some uncertainty. Accordingly, due to the absence of such guidance, it is not possible to predict whether the IRS or a court considering the issue would take a contrary position. If the Domestication should fail to qualify as a reorganization under Section 368(a) of the Code, a U.S. Holder (as that term is defined in the section entitled “Proposal 1: The Domestication Proposal — Federal Income Tax Consequences of the Domestication to Tenzing Shareholders and Warrant Holders”) of Tenzing Shares generally would recognize a gain or loss with respect to its Tenzing Shares in an amount equal to the difference, if any, between the fair market value of the corresponding common stock of the Delaware corporation received in the Domestication and the U.S. Holder’s adjusted tax basis in its Tenzing Shares surrendered.

As discussed more fully under the section entitled “Proposal 1: The Domestication Proposal — Material U.S. Federal Income Tax Consequences of the Domestication to Tenzing Shareholders and Warrant Holders” below, it is intended that the Domestication will constitute a tax-free reorganization within the meaning of Section 368(a)(l)(F) of the Code.

Upon effectiveness of the Domestication, the rights of holders of the Company’s common stock arising under the DGCL will differ from and may be less favorable to the rights of holders of Tenzing’s ordinary shares arising under the British Virgin Islands Companies Act.

Upon the effectiveness of the Domestication, the rights of holders of the Company’s common stock will arise under the DGCL. The DGCL contains provisions that differ in some respects from those in the Companies Act, and, therefore, some rights of holders of the Company’s common stock could differ from the rights that holders of Tenzing ordinary shares currently possess. For instance, while class actions are generally not available to shareholders under British Virgin Islands law, such actions are generally available under Delaware law. This change could increase the likelihood that the Company becomes involved in costly litigation, which could have a material adverse effect on the Company.

The application of Delaware law to Tenzing as a result of the Domestication may have the effect of deterring hostile takeover attempts or a change in control. Section 203 of the Delaware General Corporation Law, or the DGCL, restricts certain “business combinations” with “interested stockholders” for three years following the date that a person becomes an interested stockholder unless: (1) the “business combination” or the transaction which caused the person or entity to become an interested stockholder is approved by the Board of Directors prior to such business combination or transactions; (2) upon the completion of the transaction in which the person or entity becomes an “interested stockholder” such interested stockholder holds at least 85% of the voting stock of the combined company not including (x) shares held by officers and directors and (y) shares held by employee benefit plans under certain circumstances; or (3) at or after the person or entity becomes an “interested stockholder,” the “business combination” is approved by the Board of Directors and holders of at least 66 2/3% of the outstanding voting stock, excluding shares held by such interested stockholder. A Delaware corporation may elect not to be governed by Section 203. We do not anticipate making such an election.

For a more detailed description of the rights of holders of the Company’s common stock under the DGCL and how they may differ from the rights of holders of Tenzing ordinary shares under the Companies Act, please see the section entitled “The Domestication Proposal — Comparison of Shareholder Rights under the Applicable Corporate Law Before and After the Domestication.”

Delaware law and the Amended and Restated Certificate of Incorporation and Bylaws will 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.

The Amended and Restated Certificate of Incorporation and Bylaws that will be in effect upon completion of the Business Combination differ from the Memorandum and Articles of Association. Among other differences, the Amended and Restated Certificate of Incorporation, and the DGCL, contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Company Board and therefore depress the trading price of the Company Common Stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of the Company Board or taking other corporate actions, including effecting changes in management. Among other things, the Amended and Restated Certificate of Incorporation and Bylaws include provisions regarding:

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in the Company Board or management.

In addition, as a Delaware corporation, the Company will generally be subject to provisions of Delaware law, including Section 203 of the DGCL. See the section entitled “Description of Reviva’s, Tenzing’s and the Company’s Securities — Capital Stock of the Company after the Business Combination — Anti-Takeover Effects of the Certificate of Incorporation, the Bylaws and Certain Provisions of Delaware Law — Business Combinations.”

Any provision of the Amended and Restated Certificate of Incorporation, Bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of the Company’s capital stock and could also affect the price that some investors are willing to pay for the Company’s common stock.

The form of the Amended and Restated Certificate of Incorporation is attached as Annex B to this proxy statement/prospectus and we urge you to read it.

The Certificate of Incorporation will designate a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between the Company and its stockholders, which could limit the Company’s stockholders’ ability to choose the judicial forum for disputes with the Company or its directors, officers, or employees.

The Amended and Restated Certificate of Incorporation will provide that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware, or if such court does not have subject matter jurisdiction, any other court located in the State of Delaware with subject matter jurisdiction, will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee or stockholder of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against the Company or its officers or directors arising pursuant to any provision of the Delaware General Corporate Law or the Amended and Restated Certificate of Incorporation or Bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) any action asserting a claim against the Company or any director or officer of the Company governed by the internal affairs doctrine of the law of the State of Delaware; provided, that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state court sitting in the State of Delaware. Additionally, the Amended and Restated Certificate of Incorporation will provide that, unless the Company consents to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended; provided, however, that such provision will not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction.

Any person or entity purchasing or otherwise acquiring any interest in any of the securities of the Company will be deemed to have notice of and consented to these provisions. These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with the Company or its directors, officers, or other employees, which may discourage lawsuits against the Company and its directors, officers, and other employees. If a court were to find these exclusive-forum provisions to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm its results of operations.

Tenzing’s officers and directors and/or their affiliates may enter into agreements concerning Tenzing’s securities prior to the Shareholders Meeting, which may have the effect of increasing the likelihood of completion of the Business Combination or decreasing the value of the Tenzing Shares.

At any time prior to the Shareholders Meeting, during a period when they are not then aware of any material nonpublic information regarding Tenzing or its securities, Tenzing’s officers and directors and/or their affiliates may enter into a written plan to purchase Tenzing’s securities pursuant to Rule 10b5-1 of the Exchange Act, and may engage in other public market purchases, as well as private purchases, of securities. In addition, at any time prior to the Shareholders Meeting, during a period when they are not then aware of any material nonpublic information regarding Tenzing or its securities, Tenzing’s officers and directors and/or their respective affiliates may (i) purchase shares from institutional and other investors who vote, or indicate an intention to vote, against the Business Combination Proposal or the other Proposals, (ii) execute agreements to purchase such shares from institutional and other investors in the future, and/or (iii) enter into transactions with institutional and other investors to provide such persons with incentives to acquire Public Shares or vote their Public Shares in favor of the Business Combination Proposal or the other Proposals. Such an agreement may include a contractual acknowledgement that such shareholder, although still the record holder of such shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its Redemption Rights. In the event that Tenzing’s officers and directors or their affiliates purchase shares in privately negotiated transactions from Public Shareholders who have already elected to exercise their Redemption Rights, such selling Public Shareholders would be required to revoke their prior elections to redeem their shares. While the exact nature of any such incentives has not been determined as of the date of this proxy statement/prospectus, they might include, without limitation, arrangements to protect such investors or holders against potential loss in value of their shares, including the granting of put options and the transfer of shares or Warrants owned by the Sponsor for nominal value to such investors or holders.

The purpose of such share purchases and other transactions by Tenzing’s officers and directors and/or their respective affiliates would be to increase the likelihood of satisfaction of the requirements that (x) the holders of the requisite number of Tenzing Shares present and voting at the Shareholders Meeting vote in favor of the Business Combination Proposal and the other Proposals and/or (y) that Tenzing will (without regard to any assets or liabilities of Reviva) have at least $5,000,001 in net tangible assets immediately prior to the Closing or satisfy the Cash Consideration Condition after taking into account holders of Public Shares that properly demanded Redemption of their shares into cash, when, in each case, it appears that such requirements would otherwise not be met.

Entering into any such arrangements may have a depressive effect on the Tenzing Shares. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares it owns, either prior to or immediately after the Shareholders Meeting.

As of the date of this proxy statement/prospectus, except as noted above, Tenzing’s directors and officers and their affiliates have not entered into any such agreements. Tenzing will file a Current Report on Form 8-K to disclose arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the Business Combination Proposal or the Redemption threshold. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

The Company’s business and operations could be negatively affected if it becomes subject to any securities litigation or shareholder activism, which could cause the Company to incur significant expense, hinder execution of business and growth strategy and impact its stock price.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Shareholder activism, which could take many forms or arise in a variety of situations, has been increasing recently. Volatility in the stock price of the Company’s common stock or other reasons may in the future cause it to become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert management’s and board of directors’ attention and resources from the Company’s business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to the Company’s future, adversely affect its relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, the Company may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, its stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

Risks Related to Tenzing

You have limited rights or interests in funds in the Trust Account. To liquidate your investment, therefore, you may be forced to sell your Public Shares or warrants, potentially at a loss.

Public Shareholders will be entitled to receive funds from the Trust Account only upon (i) such shareholder’s exercise of Redemption Rights in connection with Tenzing’s initial business combination (which will be the Business Combination should it occur) and then only in connection with those ordinary shares of Tenzing that such shareholder properly elected to redeem, subject to the limitations described herein, (ii) the Redemption of any Public Shares properly tendered in connection with a shareholder vote to amend the Memorandum and Articles of Association to (A) modify the substance or timing of Tenzing’s obligation to redeem 100% of the Public Shares if Tenzing does not complete an initial business combination by December 28, 2020 or (B) with respect to any other provision relating to shareholders’ rights or pre-business combination activity and (iii) the Redemption of Public Shares if Tenzing is unable to complete an initial business combination by December 28, 2020, subject to applicable law and as further described herein. In that case, Public Shareholders may be forced to wait beyond December 28, 2020 before they receive funds from the Trust Account. In no other circumstances will a Public Shareholder have any right or interest of any kind in the Trust Account. Accordingly, to liquidate your investment, you may be forced to sell your Public Shares or warrants, potentially at a loss.

If you or a “group” of shareholders are deemed to hold in excess of 20% of Tenzing’s Public Shares, you will lose the ability to redeem all such shares in excess of 20% of Tenzing’s Public Shares.

The Memorandum and Articles of Association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from seeking Redemption Rights with respect to more than an aggregate of 15% of the shares sold in Tenzing’s IPO, which is referred to as the “Excess Shares.” However, such shareholders may vote all their shares (including Excess Shares) for or against the Business Combination. Your inability to redeem the Excess Shares will reduce your influence over Tenzing’s ability to complete the Business Combination and you could suffer a material loss on your investment in Tenzing if you sell Excess Shares in open market transactions. Additionally, you will not receive Redemption distributions with respect to the Excess Shares if Tenzing completes the Business Combination. As a result, you will continue to hold that number of Public Shares exceeding 20% and, in order to dispose of such shares, would be required to sell such shares in open market transactions, potentially at a loss.

Tenzing’s shareholders may be held liable for claims by third parties against Tenzing to the extent of distributions received by them upon Redemption of their shares.

If Tenzing is forced to enter into an insolvent liquidation, any distributions received by shareholders could be viewed as an unlawful payment if it was proved that immediately following the date on which the distribution was made, Tenzing was unable to pay its debts as they fall due in the ordinary course of business. As a result, a liquidator could seek to recover all amounts received by Tenzing’s shareholders. Furthermore, Tenzing’s directors may be viewed as having breached their fiduciary duties to Tenzing or Tenzing’s creditors and/or having acted in bad faith, and thereby exposing themselves and Tenzing to claims, by paying public shareholders from the Trust Account prior to addressing the claims of creditors. There is no assurance that claims will not be brought against Tenzing for these reasons.

Although Tenzing seeks to have all vendors, service providers, prospective target businesses or other entities with which it does business execute agreements with Tenzing waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of Tenzing’s Public Shareholders, as well as distributions to Public Shareholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Public Shareholders or claims challenging the enforceability of the waiver.

If third parties bring claims against Tenzing, the proceeds held in the Trust Account could be reduced and the Redemption Price received by Public Shareholders may be less than $10.20 per share.

Tenzing’s placing of funds in the Trust Account may not protect those funds from third-party claims against Tenzing. Although Tenzing seeks to have all vendors, service providers, prospective target businesses or other entities with which it does business execute agreements with Tenzing waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of Tenzing’s Public Shareholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against Tenzing’s assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, Tenzing’s management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to Tenzing than any alternative.

Examples of possible instances where Tenzing may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with Tenzing and will not seek recourse against the Trust Account for any reason. Upon Redemption of Tenzing’s Public Shares, if Tenzing is unable to complete its initial business combination within the prescribed time frame, or upon the exercise of a Redemption Right in connection with the Business Combination, Tenzing will be required to provide for payment of claims of creditors that were not waived that may be brought against Tenzing within the ten years following Redemption. Accordingly, the Redemption Price received by Public Shareholders could be less than the $10.20 per share initially held in the Trust Account, due to claims of such creditors.

Pursuant to the Insider Letter Agreement, the Sponsor has agreed that it will be liable to Tenzing if and to the extent any claims by a vendor (other than the independent auditors) for services rendered or products sold to Tenzing, or a prospective target business with which Tenzing has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below $10.20 per public share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under Tenzing’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. Tenzing believes that the Sponsor’s only assets are securities of Tenzing, and Tenzing has neither undertaken any efforts to independently verify whether the Sponsor has sufficient funds available to satisfy its indemnification obligations, nor asked the Sponsor to reserve for such obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for an initial business combination and Redemptions could be reduced to less than $10.20 per Public Share without any meaningful recourse against the Sponsor. In such event, Tenzing may not be able to complete an initial business combination, and you would receive such lesser amount per share in connection with any Redemption of your Public Shares.

None of Tenzing’s officers or directors will indemnify Tenzing for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Tenzing’s directors may decide not to enforce the indemnification obligations of the Sponsor under the Insider Letter Agreement, resulting in a reduction in the amount of funds in the Trust Account available for distribution to Tenzing’s Public Shareholders.

In the event that the proceeds in the Trust Account are reduced below $10.20 per Public Share due to reductions in the value of the trust assets, net of the interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, Tenzing’s independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While Tenzing currently expects that its independent directors would take legal action on behalf of Tenzing against the Sponsor to enforce their indemnification obligations to Tenzing, it is possible that Tenzing’s independent directors in exercising their business judgment may choose not to do so in any particular instance. If Tenzing’s independent directors choose not to enforce these indemnification obligations, there may be less funds in the Trust Account available for distribution to Tenzing’s Public Shareholders.

If, after Tenzing distributes the proceeds in the Trust Account to its Public Shareholders, Tenzing files for insolvent liquidation or a petition for the insolvent liquidation of Tenzing is filed that is not dismissed, a British Virgin Islands court may seek to recover such proceeds and the members of the Tenzing Board may be viewed as having breached their fiduciary duties to Tenzing’s creditors, thereby exposing the members of the Tenzing Board and Tenzing to claims of punitive damages.

If, after Tenzing distributes the proceeds in the Trust Account to its Public Shareholders, Tenzing files a petition for insolvent liquidation or a petition for the insolvent liquidation of Tenzing is filed that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as an unlawful distribution. As a result, a British Virgin Islands court could seek to recover all amounts received by Tenzing’s shareholders. In addition, the Tenzing Board may be viewed as having breached its fiduciary duty to Tenzing’s creditors and/or having acted in bad faith, thereby exposing itself and Tenzing to claims of punitive damages, by paying Public Shareholders from the Trust Account prior to addressing the claims of creditors.

Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect the business, investments and results of operations of Tenzing.

Tenzing is subject to laws and regulations enacted by national, regional and local governments. In particular, Tenzing is required to comply with certain SEC and other legal requirements. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time and those changes could have a material adverse effect on the business, investments and results of operations of Tenzing. In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on Tenzing’s business and results of operations.

The Insider Letter Agreement may be amended without shareholder approval.

The Insider Letter Agreement with Tenzing’s Sponsor, directors and officers contains provisions relating to transfer restrictions of Tenzing’s Founder Shares and Private Placement Units (including the underlying securities), indemnification of the Trust Account, waiver of Redemption Rights and participation in liquidation distributions from the Trust Account. The Insider Letter Agreement may be amended without shareholder approval. While Tenzing does not expect the Tenzing Board to approve any amendment to this agreement prior to the Business Combination, it may be possible that the Tenzing Board, in exercising its business judgment and subject to its fiduciary duties and any restrictions under the Merger Agreement, chooses to approve one or more amendments to such agreement. Any such amendment may have an adverse effect on the value of an investment in Tenzing’s securities.

The Sponsor controls a substantial interest in Tenzing and thus may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support.

The Sponsor owns 30.9% of Tenzing’s issued and outstanding ordinary shares. Accordingly, they may exert a substantial influence on actions requiring a shareholder vote, including the matters to be considered at the Shareholders Meeting, potentially in a manner that you do not support. If the Sponsor purchases any additional ordinary shares in the aftermarket or in privately negotiated transactions, this would increase its control. Neither the Sponsor nor, to Tenzing’s knowledge, any of Tenzing’s officers or directors, have any current intention to purchase additional securities, other than as may be disclosed in this proxy statement/prospectus. Factors that would be considered in making such additional purchases would include consideration of the current trading price of Tenzing’s ordinary shares. Tenzing will not hold an annual meeting of shareholders to elect new directors prior to the consummation of the Business Combination, in which case all of the current directors will continue in office until at least the completion of the Business Combination. Accordingly, the Sponsor will continue to exert control at least until the consummation of the Business Combination.

Your unexpired Warrants may be redeemed prior to their exercise at a time that is disadvantageous to you, thereby making your Warrants worthless.

Outstanding Warrants may be redeemed at any time after they become exercisable and prior to their expiration, at a price of $0.01 per Warrant, provided that the last reported sales price of Tenzing’s ordinary shares equals or exceeds $21.00 per share for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date Tenzing sends the notice of redemption to the warrant holders. If and when the warrants become redeemable by Tenzing, Tenzing may not exercise its redemption rights if the issuance of ordinary shares upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or Tenzing is unable to effect such registration or qualification, subject to its obligation in such case to use its best efforts to register or qualify the ordinary shares of common stock under the blue sky laws of the state of residence in those states in which the warrants were initially offered by Tenzing in its IPO. Redemption of the outstanding warrants could force you (i) to exercise your warrants and pay the exercise price at a time when it may be disadvantageous for you to do so, (ii) to sell your warrants at the then-current market price when you might otherwise wish to hold your warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely to be substantially less than the market value of your warrants. None of the Private Placement Warrants will be redeemable by Tenzing so long as they are held by their initial purchasers — the Sponsor and Maxim — or their permitted transferees.

Tenzing is an emerging growth company within the meaning of the Securities Act and Tenzing has taken advantage of certain exemptions from disclosure requirements available to emerging growth companies; this could make the Company’s securities less attractive to investors and may make it more difficult to compare the Company’s performance with other public companies.

Tenzing (and the Company following the Business Combination) is an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act and has taken advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in Tenzing’s periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on certain executive compensation matters. As a result, Tenzing’s shareholders may not have access to certain information they may deem important. Tenzing and the Company may be an emerging growth company for up to five years from the IPO, although circumstances could cause the loss of that status earlier, including if the market value of the common stock of the Company held by non-affiliates exceeds $700 million as of the last business day in any August before that time, in which case the Company would no longer be an emerging growth company as of the following February 28. Tenzing cannot predict whether investors will find its (or the Company’s) securities less attractive because Tenzing (or the Company) rely on these exemptions. If some investors find the securities less attractive as a result of reliance on these exemptions, the trading prices of the Company’s securities may be lower than they otherwise would be, there may be a less active trading market for the Company’s securities and the trading prices of the securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. Tenzing has elected not to opt out of such extended transition period. Accordingly, when a standard is issued or revised and it has different application dates for public or private companies, Tenzing (or the Company following the Business Combination), as an emerging growth company, will adopt the new or revised standard at the time private companies adopt the new or revised standard, unless early adoption is permitted by the standard. This may make comparison of Tenzing’s and the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for Tenzing to effectuate the Business Combination, require substantial financial and management resources and increase the time and costs of completing an acquisition.

Section 404 of the Sarbanes-Oxley Act requires that Tenzing evaluate and report on its system of internal controls. Following the initial Business Combination, if the Company is deemed to be a large accelerated filer or an accelerated filer, it will be required to comply with the independent registered public accounting firm attestation requirement on its internal control over financial reporting. Further, for as long as the Company remains an emerging growth company, it will not be required to comply with the independent registered public accounting firm attestation requirement on its internal control over financial reporting. Following the Business Combination, the Company will be required to assure that it is in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of its internal controls. The need to develop the internal control system to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete the Business Combination as well as impose obligations of the Company following the Business Combination.

Risks Related to Reviva’s Business and Industry

Following the Business Combination, the Company will be a holding company with no direct operations that relies on dividends, distributions, loans and other payments, advances and transfers of funds from Reviva and its subsidiary to pay dividends, pay expenses and meet its other obligations. Accordingly, the Company’s stockholders will be subject to all of the risks of Reviva’s business following the Business Combination. Throughout this section, unless otherwise noted, “Reviva” refers to Reviva Pharmaceuticals, Inc. and its consolidated subsidiary.

Risks Related to Reviva’s Business, Financial Position and Capital Requirements

Reviva has never generated any product revenues.

Reviva is a clinical-stage biopharmaceutical company. Although Reviva was formed in May 2006, to date, Reviva has not generated any product revenues from its product candidates currently in development. Reviva has not yet demonstrated an ability to successfully complete a large-scale, pivotal clinical trial, obtain marketing approval, manufacture a commercial scale product, or arrange for a third-party to do so on its behalf, or conduct sales and marketing activities necessary for successful product commercialization.

Consequently, Reviva has no meaningful operations upon which to evaluate its business and predictions about Reviva’s future success or viability may not be as accurate as they could be if Reviva had a history of successfully developing and commercializing pharmaceutical products.

Reviva’s ability to generate revenue and become profitable depends upon its ability to successfully complete the development of Reviva’s product candidates, RP5063 for the treatment of schizophrenia, respiratory/pulmonary diseases such as Pulmonary Arterial Hypertension, or PAH, and Idiopathic Pulmonary Fibrosis, or IPF, and for other neuropsychiatric diseases, such as bipolar disorder, or BD, major depressive disorder, or MDD, Alzheimer’s psychosis/agitation, or AD, Parkinson’s psychosis, or PD, and attention deficit hyperactivity disorder, or ADHD/ADD, and RP1208 for the treatment of depression and obesity, and obtain the necessary regulatory approvals for their commercialization. Reviva has never been profitable, has no products approved for commercial sale and to date has not generated any revenue from product sales.

Even if Reviva receives regulatory approval for the commercialization of RP5063, Reviva does not know when this product candidate will generate revenue, if at all. RP1208 is in pre-clinical development. Reviva’s ability to generate product revenue depends on a number of factors, including its ability to:

Because of the numerous risks and uncertainties associated with product development, Reviva is unable to predict the timing or amount of increased expenses, or when, or if, Reviva will be able to achieve or maintain profitability. Reviva’s expenses could increase beyond expectations if Reviva is required by the U.S. Food and Drug Administration, or the FDA, and comparable non-U.S. regulatory authorities, to perform studies or clinical trials in addition to those that it currently anticipates. Even if Reviva’s product candidates are approved for commercial sale, Reviva anticipates incurring significant costs associated with the commercial launch of these products. If Reviva cannot successfully execute any one of the foregoing, its business, prospects and results of operations may be adversely affected.

Reviva expects to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

Investment in pharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a product candidate will fail to gain regulatory approval or become commercially viable. Reviva has never generated any revenues and cannot estimate with precision the extent of its future losses. Reviva does not currently have any products that are available for commercial sale and Reviva may never generate revenue from selling products or achieve profitability. Reviva expects to continue to incur substantial and increasing losses through the projected commercialization of RP5063 and RP1208. For the six months ended June 30, 2020, Reviva reported a loss of $1,600,395, and a negative cash flow from operations of $415,395. Reviva had an accumulated deficit of $56,127,100 and had cash and cash equivalents of $194,798 as of June 30, 2020.

RP5063 has not been approved for marketing in the United States and may never receive such approval. Although RP1208 may be in IND enabling studies for depression and may be in animal efficacy studies for obesity within a short time frame following the receipt of adequate additional financing, it is not currently in an IND-enabling study or animal efficacy study, respectively, and may never meet the requirements for filing an IND. As a result, Reviva is uncertain when or if it will achieve profitability and, if so, whether Reviva will be able to sustain it. Reviva’s ability to produce revenue and achieve profitability is dependent on its ability to complete the development of its product candidates, obtain necessary regulatory approvals, and have its product candidates manufactured and successfully marketed. Reviva cannot assure you that it will be profitable even if it successfully commercializes its product candidates. If it does successfully obtain regulatory approval to market its product candidates, its revenues will be dependent, in part, upon, among other things, the size of the markets in the territories for which Reviva gains regulatory approval, the number of competitors in such markets, the accepted price for its product candidates and whether Reviva owns the commercial rights for that territory. If the indication approved by regulatory authorities is narrower than Reviva expects, or the treatment population is narrowed by competition, physician choice or treatment guidelines, Reviva may not generate significant revenue from sales of its product candidates, even if approved. Even if Reviva does achieve profitability, Reviva may not be able to sustain or increase profitability on a quarterly or annual basis. Failure to become and remain profitable may adversely affect the timing of Reviva’s clinical results and its ability to raise capital and continue operations.

Reviva expects its research and development expenses to be significant in connection with the following planned research:

Further, Reviva will require additional capital to proceed with the planned research described above. See “Risks Related to Reviva’s Business and Industry - Risks Related to Reviva’s Business, Financial Position and Capital Requirements - Reviva will require additional capital to fund its operations, and if Reviva fails to obtain necessary financing, Reviva may not be able to complete the development and commercialization of RP5063.”

In addition, if Reviva obtains regulatory approval for RP5063, Reviva expects to incur increased sales and marketing expenses. As a result, Reviva expects to continue to incur significant and increasing operating losses and negative cash flows for the foreseeable future. These losses have had and will continue to have an adverse effect on Reviva’s financial position and working capital.

Reviva is heavily dependent on the success of RP5063, its only advanced product candidate, which is still under clinical development, and if RP5063 does not receive regulatory approval or is not successfully commercialized, Reviva’s business will be harmed.

Reviva currently has no products that are approved for commercial sale and may never be able to develop marketable drug products. Reviva expects that a substantial portion of its efforts and expenditures in the foreseeable future will be devoted to RP5063. Reviva’s only other product candidate is RP1208, which is in the pre-clinical phase. Reviva does not expect to allocate a significant portion of its efforts or resources to the clinical trials or development of this product candidate in the foreseeable future. Accordingly, Reviva’s business currently depends heavily on the successful development, regulatory approval and commercialization of RP5063. Reviva cannot be certain that RP5063 will receive regulatory approval or be successfully commercialized even if Reviva receives regulatory approval. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of drug products are and will remain subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries that each have differing regulations. Reviva is not permitted to market RP5063 in the United States until it receives approval of a new drug application, or NDA, from the FDA, or in any foreign countries until it receives the requisite approval from such countries. Reviva has not submitted an NDA to the FDA or comparable applications to other regulatory authorities and does not expect to be in a position to do so for the foreseeable future. Obtaining approval of an NDA is an extensive, lengthy, expensive and inherently uncertain process, and the FDA may delay, limit or deny approval of RP5063 for many reasons, including:

The COVID-19 outbreak and global pandemic could adversely impact Reviva’s business, including its clinical trials.

Public health crises such as pandemics or similar outbreaks could adversely impact Reviva’s business. In December 2019, a novel strain of coronavirus, or COVID-19, surfaced in Wuhan, China. Since then, COVID-19 has spread globally. As a result of the COVID-19 outbreak, or similar pandemics, and government response to pandemics, Reviva has and may in the future experience disruptions that could severely impact its business and clinical trials, including:

The COVID-19 outbreak continues to rapidly evolve. The extent to which the outbreak may impact Reviva’s business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and actions to contain the outbreak or treat its impact, such as social distancing and quarantines or lock-downs in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

Reviva will require additional capital to fund its operations, and if Reviva fails to obtain necessary financing, Reviva may not be able to complete the development and commercialization of RP5063 or RP1208.

Reviva expects to spend substantial amounts to complete the development of, seek regulatory approvals for, and commercialize RP5063 and RP 1208. With the expected proceeds from the Business Combination and potential proceeds from a PIPE Investment, Reviva intends to proceed with the development and potential commercialization of RP5063 for the treatment of schizophrenia. However, Reviva will require additional capital to complete the development and potential commercialization of RP5063 for the treatment of schizophrenia and to continue the development of RP5063 for PAH, IPF, BD, MDD, AD, PD, ADHD/ADD and other potential indications, and to continue the development of RP1208 for the treatment of depression and obesity. No assurance can be given that such additional capital will be available on terms acceptable to Reviva, if at all. If Reviva is unable to raise capital when needed or on acceptable terms, Reviva could be forced to delay, reduce or eliminate its planned development programs or any future commercialization efforts. In addition, attempting to secure additional financing may divert the time and attention of Reviva’s management from day-to-day activities and harm Reviva’s product candidate development efforts. Because the length of time and activities associated with successful development of RP5063 and RP1208 is highly uncertain, Reviva is unable to estimate the actual funds it will require for development and any approved marketing and commercialization activities. Reviva’s future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

Reviva cannot be certain that such funding will be available on acceptable terms, or at all. If Reviva is unable to raise additional capital in sufficient amounts or on terms acceptable to Reviva, Reviva may have to significantly delay, scale back or discontinue the development or commercialization of RP5063 or RP1208 or potentially discontinue operations.

Raising additional funds by issuing securities may cause dilution to existing shareholders, and raising funds through lending and licensing arrangements may restrict Reviva’s operations or require it to relinquish proprietary rights.

Reviva expects that significant additional capital will be needed in the future to continue its planned operations. Until such time, if ever, as Reviva can generate substantial product revenues, Reviva expects to finance its cash needs through a combination of equity offerings, debt financings, strategic alliances and license and development agreements in connection with any collaborations. Reviva does not have any committed external source of funds. To the extent that Reviva raises additional capital by issuing equity securities, Reviva’s existing shareholders’ ownership may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect then-existing stockholders’ interests. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting Reviva’s ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If Reviva raises additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, Reviva may have to relinquish valuable rights to its technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to Reviva. Any debt financing Reviva enters into may involve covenants that restrict its operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of Reviva’s assets as well as prohibitions on its ability to create liens, pay dividends, redeem Reviva’s shares or make investments. If Reviva is unable to raise additional funds through equity or debt financings when needed, Reviva may be required to delay, limit, reduce or terminate its product development or future commercialization efforts or grant rights to develop and market product candidates that Reviva would otherwise develop and market itself.

Reviva will need to expand its organization, and Reviva may experience difficulties in managing this growth, which could disrupt its operations.

As of September 30, 2020, Reviva had 4 employees, and Reviva is highly dependent on its management personnel, especially its Chief Executive Officer, Laxminarayan Bhat. Following the completion of the Business Combination, Reviva expects to hire a significant number of additional employees for its managerial, clinical, scientific, operational, sales and marketing teams. Reviva may have operational difficulties in connection with identifying, hiring and integrating new personnel. Future growth would impose significant additional responsibilities on Reviva’s management, including the need to identify, recruit, maintain, motivate and integrate additional employees, consultants and contractors. Also, Reviva’s management has no prior experience in managing these growth activities, and may need to divert a disproportionate amount of its attention away from Reviva’s day-to-day activities and devote a substantial amount of time to such activities. Reviva may not be able to effectively manage the expansion of its operations, which may result in weaknesses in Reviva’s infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Reviva’s expected growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of product candidates. If Reviva’s management is unable to effectively manage its growth, Reviva’s expenses may increase more than expected, its ability to generate and/or grow revenues could be reduced, and Reviva may not be able to implement its business strategy. Reviva’s future financial performance and Reviva’s ability to commercialize RP5063 and RP1208 and compete effectively will depend, in part, on Reviva’s ability to effectively manage any future growth.

Many of the other pharmaceutical companies that Reviva competes against for qualified personnel and consultants have greater financial and other resources, different risk profiles and a longer history in the industry than Reviva. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates and consultants than what Reviva has to offer. If Reviva is unable to continue to attract and retain high-quality personnel and consultants, the rate and success at which Reviva can discover and develop product candidates and Reviva’s business will be limited.

Reviva’s employees, independent contractors, principal investigators, consultants, commercial collaborators, service providers and other vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on Reviva’s results of operations.

Reviva is exposed to the risk that its employees and contractors, including principal investigators, consultants, commercial collaborators, service providers and other vendors may engage in fraudulent or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or other unauthorized activities that violate the laws and regulations of the FDA and other similar regulatory bodies, including those laws that require the reporting of true, complete and accurate information to such regulatory bodies; manufacturing standards; federal and state healthcare fraud and abuse and health regulatory laws and other similar foreign fraudulent misconduct laws; or laws that require the true, complete and accurate reporting of financial information or data. Activities subject to these laws also involve the improper use or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to Reviva’s reputation. It is not always possible to identify and deter third-party misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting Reviva from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against Reviva, and Reviva is not successful in defending itself or asserting its rights, those actions could have a significant impact on Reviva’s business and financial results, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, reputational harm, diminished profits and future earnings, and curtailment of Reviva’s operations, any of which could adversely affect Reviva’s ability to operate its business and its results of operations.

If Reviva seeks to enter into strategic alliances for the development of RP5063 or RP1208 but fails to enter into and maintain successful strategic alliances, Reviva’s development costs may increase and its ability to develop RP5063 or RP1208 may be significantly delayed.

Reviva may seek to enter into strategic alliances or collaborative arrangements with pharmaceutical companies or other industry participants in order to advance its development of RP5063 or, in the future, RP1208 or other product candidates, and to reduce Reviva’s costs of development. If Reviva seeks such alliances or collaborative arrangements, Reviva may not be able to negotiate such alliances or collaborative arrangements on acceptable terms, if at all. Reviva faces significant competition from other biopharmaceutical companies for appropriate partners in such alliances or arrangements. Furthermore, if Reviva is successful in entering strategic alliances or collaborative arrangements, Reviva may not be able to maintain such alliances or arrangements for a sufficient amount of time to commercialize RP5063, RP1208 or other product candidates, or such alliances or arrangements may not result in successful development of Reviva’s products. If Reviva seeks suitable alliances or arrangements but then fail to create or to maintain these, Reviva may have to limit the size or scope of, or delay, its development of RP5063, RP1208 or other future product candidates. If Reviva elects to fund its development or research programs on its own, Reviva will have to increase its expenditures and will need to obtain additional funding, which may be unavailable or available only on unfavorable terms. See “Risks Related to Reviva’s Business and Industry - Risks Related to Reviva’s Business, Financial Position and Capital Requirements - Reviva will require additional capital to fund its operations, and if Reviva fails to obtain necessary financing, Reviva may not be able to complete the development and commercialization of RP5063.”

To the extent Reviva is able to enter into collaborative arrangements or strategic alliances, Reviva will be exposed to risks related to those collaborations and alliances.

Biotechnology companies at Reviva’s stage of development may become dependent upon collaborative arrangements or strategic alliances to complete the development and commercialization of drug candidates, particularly after the phase 2 stage of clinical testing. If Reviva elects to enter into collaborative arrangements or strategic alliances, these arrangements may place the development of RP5063, RP1208 or other future product candidates outside Reviva’s control, may require Reviva to relinquish important rights or may otherwise be entered on terms unfavorable to Reviva.

Dependence on collaborative arrangements or strategic alliances will subject Reviva to a number of risks, including the risk that:

Reviva’s business and operations would suffer in the event its computer systems and networks fail.

Reviva’s business depends on the proper functioning and availability of its computer systems and networks. Reviva’s computer systems, as well as those of its CROs and other contractors and consultants, are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. If such an event were to occur and cause interruptions in Reviva’s operations, it could result in a material disruption of Reviva’s drug development programs. For example, the loss of preclinical or clinical trial data from completed, ongoing or planned trials could result in delays in Reviva’s regulatory approval efforts and significantly increase its costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to Reviva’s data or applications, or inappropriate disclosure of personal, confidential or proprietary information, Reviva could incur liability and the further development of RP5063, RP1208 or any future product candidate could be delayed.  Any successful cyber security attack or other unauthorized attempt to access Reviva’s systems also could result in negative publicity which could damage its reputation or brand with its patients, referral sources, payors or other third parties and could subject Reviva to substantial penalties under HIPAA and other federal and state privacy laws, in addition to private litigation with those affected.

Potential product liability lawsuits against Reviva could cause Reviva to incur substantial liabilities and limit commercialization of any products that Reviva may develop.

The use of RP5063 and RP1208 in clinical trials and the sale of any products for which Reviva obtains marketing approval exposes Reviva to the risk of product liability claims. Product liability claims might be brought against Reviva by consumers, health care providers, pharmaceutical companies or others selling or otherwise coming into contact with its products. On occasion, large judgments have been awarded in class action lawsuits based on drugs that had unanticipated adverse effects. If Reviva cannot successfully defend against product liability claims, Reviva could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product liability claims may result in:

Any product liability insurance coverage Reviva acquires in the future may not be sufficient to reimburse Reviva for any expenses or losses it may suffer. Moreover, insurance coverage is becoming increasingly expensive and in the future Reviva may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect it against losses due to liability. If Reviva obtains marketing approval for RP5063 or RP1208, Reviva intends to acquire insurance coverage to include the sale of commercial products; however, Reviva may be unable to obtain product liability insurance on commercially reasonable terms or in adequate amounts. A successful product liability claim or series of claims brought against Reviva could cause its share price to decline and, if judgments exceed Reviva’s insurance coverage, could adversely affect Reviva’s results of operations and business, including preventing or limiting the commercialization of any product candidates it develops.

Risks Related to Clinical Development, Regulatory Approval and Commercialization

Clinical trials are very expensive, time-consuming, difficult to design and implement and involve an uncertain outcome.

Reviva’s only advanced product candidate, RP5063, is still in development and will require extensive clinical testing before Reviva is prepared to submit an NDA for regulatory approval. Reviva cannot predict with any certainty if or when it might submit an NDA for regulatory approval for RP5063 or whether any such NDA will be approved by the FDA. Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming. Reviva estimates that the phase 3 clinical trials of RP5063 for schizophrenia indication will take at least four years to complete. Furthermore, failure can occur at any stage of the trials, and Reviva could encounter problems that cause it to abandon or repeat clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials, and the results of early clinical trials of RP5063 therefore may not be predictive of the results of Reviva’s planned phase 3 clinical study.

The commencement and completion of clinical trials may be delayed by one or more factors, including:

In addition, Reviva’s management has limited prior experience in managing and completing late-stage clinical trials, and may not be able to successfully design and implement these trials or respond to adverse factors that may arise in the course of conducting these trials.

Further, Reviva, the FDA or an institutional review board, or IRB, at a clinical trial site may suspend Reviva’s clinical trials at any time if it appears that Reviva or its collaborators are failing to conduct a trial in accordance with regulatory requirements, including the FDA’s current Good Clinical Practice, or GCP, regulations, that Reviva is exposing participants to unacceptable health risks, or if the FDA finds deficiencies in Reviva’s investigational new drug, or IND, submissions or the conduct of these trials.

Therefore, Reviva cannot predict with any certainty the schedule for commencement and completion of future clinical trials. If Reviva experiences delays in the commencement or completion of its clinical trials, or if Reviva terminates a clinical trial prior to completion, the commercial prospects of RP5063 could be harmed, and Reviva’s ability to generate revenues from RP5063 may be delayed. In addition, any delays in Reviva’s clinical trials could increase Reviva’s costs, slow down the approval process and jeopardize its ability to commence product sales and generate revenues. Any of these occurrences may harm Reviva’s business, financial condition and results of operations.

Moreover, while Reviva is not currently intending to engage any principal investigators as advisors or consultants, it is conceivable that principal investigators for Reviva’s clinical trials may serve as scientific advisors or consultants from time to time and receive compensation in connection with such services. Under certain circumstances, Reviva may be required to report some of these relationships to the FDA. The FDA may conclude that a financial relationship between Reviva and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. FDA may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of Reviva’s marketing applications by the FDA and may ultimately lead to the denial of marketing approval of one or more of Reviva’s product candidates.

The results of Reviva’s clinical trials may not support its RP5063, RP1208 and any future product candidate claims.

Even if Reviva’s clinical trials are completed as planned, Reviva cannot be certain that its results will support the safety and effectiveness of RP5063 for the treatment of schizophrenia or any other potential indication, including but not limited to PAH, IPF, BD, MDD, AD, PD, ADHD/ADD, or any of other product candidates, including RP1208. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and Reviva cannot be sure that the results of later clinical trials will replicate the results of prior clinical trials and preclinical testing. A failure of a clinical trial to meet its predetermined endpoints would likely cause Reviva to abandon a product candidate and may delay development of any other product candidates. Any delay in, or termination of, Reviva’s clinical trials will delay the submission of Reviva’s NDAs with the FDA and, ultimately, Reviva’s ability to commercialize RP5063, RP1208 or any future product candidate, and generate product revenues.

Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be made more difficult or rendered impossible by multiple factors outside Reviva’s control.

Reviva may encounter delays in enrolling, or be unable to enroll, a sufficient number of patients to complete any of its clinical trials, and even once enrolled Reviva may be unable to retain a sufficient number of patients to complete any of its trials. Patient enrollment and retention in clinical trials depends on many factors, including the size of the patient population, the nature of the trial protocol, the existing body of safety and efficacy data with respect to the study drug, the number and nature of competing treatments and ongoing clinical trials of competing drugs for the same indication, the proximity of patients to clinical sites and the eligibility criteria for the study. Furthermore, any negative results Reviva may report in clinical trials of its product candidate may make it difficult or impossible to recruit and retain patients in other clinical trials of that same product candidate. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on Reviva’s ability to develop RP5063, RP1208 or any future product candidate, or could render further development impossible. In addition, Reviva expects to rely on CROs and clinical trial sites to ensure proper and timely conduct of Reviva’s future clinical trials and, while Reviva intends to enter into agreements governing their services, Reviva will be limited in its ability to compel their actual performance.

The continued spread of COVID-19 globally could adversely impact Reviva’s clinical trial operations, including its ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak occurs in their geography. Disruptions or restrictions on the ability of patients enrolled in Reviva’s clinical studies to travel, or the ability of staff at study sites to travel, as well as temporary closures of Reviva’s facilities or the facilities of Reviva’s clinical trials partners and their contract manufacturers, would negatively impact Reviva’s clinical trial activities.

Reviva faces significant competition from other biotechnology and pharmaceutical companies, and Reviva’s operating results will suffer if it fails to compete effectively.

Drug development is highly competitive and subject to rapid and significant technological advancements. As a significant unmet medical need exists for the treatment of schizophrenia, there are several large and small pharmaceutical companies focused on delivering therapeutics for the treatment of schizophrenia. Further, it is likely that additional drugs will become available in the future for the treatment of schizophrenia.

Reviva is aware of other companies that are working to develop drugs that would compete against RP5063 for schizophrenia treatment. Many of Reviva’s existing or potential competitors have substantially greater financial, technical and human resources than Reviva does and significantly greater experience in the discovery and development of product candidates, as well as in obtaining regulatory approvals of those product candidates in the United States and in foreign countries. Reviva’s current and potential future competitors also have significantly more experience commercializing drugs that have been approved for marketing.

Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a small number of Reviva’s competitors.

Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Reviva’s competitors may succeed in developing, acquiring or licensing, on an exclusive basis, drugs that are more effective or less costly than any product candidate that Reviva may develop.

Reviva will face competition from other drugs currently approved or that will be approved in the future for the treatment of schizophrenia. Therefore, Reviva’s ability to compete successfully will depend largely on its ability to:

The availability of Reviva’s competitors’ products could limit the demand, and the price Reviva is able to charge, for any product candidate it develops. The inability to compete with existing or subsequently introduced drugs would have an adverse impact on Reviva’s business, financial condition and prospects.

Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make RP5063 less competitive. In addition, any new product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, Reviva’s competitors may succeed in obtaining patent protection, receiving FDA approval for or commercializing medicines before Reviva does, which would have an adverse impact on Reviva’s business and results of operations.

If Reviva is not able to obtain required regulatory approvals, Reviva will not be able to commercialize RP5063, RP1208 or any other product candidates, and its ability to generate revenue will be materially impaired.

RP5063 and the activities associated with its development and commercialization, including its design, research, testing, manufacture, safety, efficacy, recordkeeping, labeling, packaging, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by the EMA and similar regulatory authorities outside the United States. Failure to obtain marketing approval for RP5063 will prevent Reviva from commercializing it.

Reviva has not received approval from regulatory authorities to market any product candidate in any jurisdiction, and it is possible that none of RP5063, RP1208 nor any other product candidates Reviva may seek to develop in the future will ever obtain the appropriate regulatory approvals necessary for Reviva to commence product sales.

Prior to submitting an NDA to the FDA, a marketing authorization application, or MAA, to the EMA, or an equivalent application to other foreign regulatory authorities for approval of RP5063, Reviva will need to complete its phase 3 clinical study.

Reviva expects to rely on third-party CROs and consultants to assist it in filing and supporting the applications necessary to gain marketing approvals. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish RP5063’s safety and efficacy for that indication. Securing marketing approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities.

Reviva may not be able to obtain or maintain orphan drug designation or exclusivity for its product candidate.

Reviva has been granted orphan drug designation in the United States for RP5063 for the treatment of IPF and PAH. Upon receipt of regulatory approval, orphan drug status will provide Reviva with seven years of market exclusivity in the United States under the Orphan Drug Act. However, there is no guarantee that the FDA will grant orphan drug designation for any of its drug candidates for any future indication, which would make Reviva ineligible for the additional exclusivity and other benefits of orphan drug designation. Moreover, there can be no assurance that another company also holding orphan drug designation for the same indication or which may receive orphan drug designation in the future will not receive approval prior to Reviva, in which case Reviva’s competitor would have the benefit of the seven years of market exclusivity, and Reviva would be unable to commercialize its product candidate for the same indication until the expiration of such seven-year period. Even if Reviva is the first to obtain approval for the orphan drug indication, there are circumstances under which a competing product may be approved for the same indication during Reviva’s seven-year period of exclusivity.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a drug available in the Unites States for this type of disease or condition will be recovered from sales of the product. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan designation does not convey any advantage in or shorten the duration of regulatory review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company eligible for grant funding of up to $400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption from the FDA application user fee.

If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is withdrawn; (iii) the orphan exclusivity holder consents to the approval of another applicant’s product; (iv) the orphan exclusivity holder is unable to assure the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the product with orphan exclusivity by a competitor product. If a drug designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan drug exclusivity. There can be no assurance that Reviva will receive orphan drug designation for RP5063 for any additional indications or for RP1208, if Reviva elects to seek such designation.

RP5063, RP1208 and any future product candidate may cause adverse effects or have other properties that could delay or prevent its regulatory approval or limit the scope of any approved label or market acceptance.

Adverse events caused by RP5063, RP1208 and any future product candidate could cause Reviva, other reviewing entities, clinical trial sites or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of regulatory approval. If an unacceptable frequency or severity of adverse events are reported in Reviva’s clinical trials for RP5063, RP1208 or any future product candidates, Reviva’s ability to obtain regulatory approval for such product candidates may be negatively impacted.

Furthermore, if any of Reviva’s product candidates are approved and then cause serious or unexpected side effects, a number of potentially significant negative consequences could result, including:

Any of these events could prevent Reviva from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing RP5063, RP1208 and any future product candidate.

Because the results of pre-clinical testing are not necessarily predictive of future results, RP1208 may not have favorable results in Reviva’s planned clinical trials.

Any positive results from Reviva’s pre-clinical testing of RP1208 may not necessarily be predictive of the results from Reviva’s planned clinical trials. Many companies in the pharmaceutical industry have suffered significant setbacks in clinical trials after achieving positive results in pre-clinical development, and Reviva cannot be certain that it will not face similar setbacks. The pre-clinical data Reviva has obtained for RP1208 may not predict results from studies in larger numbers of subjects drawn from more diverse populations or in a commercial setting, and also may not predict the ability of RP1208 to achieve its intended goals, or to do so safely.

Moreover, pre-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in pre-clinical studies and clinical trials nonetheless failed to obtain FDA or EMA approval. If Reviva fails to produce positive results in its clinical trials, the development timeline and regulatory approval and commercialization prospects for its products and, correspondingly, Reviva’s business and financial prospects, would be materially adversely affected.

Even if Reviva obtains FDA approval for RP5063, RP1208 or any future product candidate in the United States, Reviva may never obtain approval for or commercialize it in any other jurisdiction, which would limit Reviva’s ability to realize its full market potential.

In order to market any products in any particular jurisdiction, Reviva must establish and comply with numerous and varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by FDA in the United States does not ensure approval by regulatory authorities in other countries or jurisdictions. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approval could result in difficulties and costs for us and require additional preclinical studies or clinical trials which could be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of Reviva’s products in those countries. Reviva does not have any product candidates approved for sale in any jurisdiction, including in international markets, and Reviva does not have experience in obtaining regulatory approval in international markets. If Reviva fails to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in international markets are delayed, Reviva’s target market will be reduced and Reviva’s ability to realize the full market potential of any product it develops will be unrealized.

Even if Reviva obtains regulatory approval for RP5063, RP1208 or any future product candidate, Reviva will still face extensive regulatory requirements and its products may face future development and regulatory difficulties.

Any product candidate for which Reviva obtains marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, packaging, distribution, adverse event reporting, storage, recordkeeping, export, import, advertising and promotional activities for such product, among other things, will be subject to extensive and ongoing requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, establishment registration and drug listing requirements, continued compliance with current Good Manufacturing Practice, or cGMP, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping and current GCP requirements for any clinical trials that Reviva conducts post-approval. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including any requirement to implement a REMS. If RP5063, RP1208 or any future product candidate receives marketing approval, the accompanying label may limit the approved use of Reviva’s drug candidate, which could limit sales of the product.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the product. The FDA closely regulates the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if Reviva does not market its products for their approved indications, Reviva may be subject to enforcement action for off-label marketing. Violations of the Federal Food, Drug, and Cosmetic Act relating to the promotion of prescription drugs may lead to FDA enforcement actions and investigations alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with Reviva’s products, manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:
