This may make comparison of the Company’s consolidated 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. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Use of Estimates </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Making estimates requires management to exercise significant judgment.

The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">paid-in</div> capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">non-cash</div> gain or loss on the statements of operations. The fair value of the Placement Warrants was estimated using a Black Scholes valuation approach (see Note 10). </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Income Taxes </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company complies with the accounting and reporting requirements of ASC Topic 740 “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">more-likely-than-not</div> to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2021 and December 31, 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The effective tax rate differs from the statutory tax rate of 25% for the three months ended March 31, 2021 and 2020 primarily due to permanent differences. </div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company may be subject to potential examination by federal, state and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Net Income (Loss) Income Per Common Share </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Net income (loss) per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. The Company has not considered the effect of (1) warrants sold in the Initial Public Offering and private placement to purchase 3,586,250 shares of common stock, (2) rights sold in the Initial Public Offering and private placement that convert into 717,250 shares of common stock and (3) 600,000 shares of common stock, warrants to purchase 300,000 shares of common stock and rights that convert into 60,000 shares of common stock in the unit purchase option sold to the underwriter, in the calculation of diluted (loss) income per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. </div><br/></div><div style="font-size: 1px; margin-top: 18px; margin-bottom: 0px;"><div style="font-size: 1px; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"> </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Concentration of Credit Risk </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000.

ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Level 1—Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Level 2—Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">Level 3—Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying consolidated balance sheets, primarily due to their short-term nature. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">See Note 10 for additional information on assets and liabilities measured at fair value. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Derivative Financial Instruments </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">re-valued</div> at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">non-current</div> based on whether or not <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">net-cash</div> settlement or conversion of the instrument could be required within 12 months of the balance sheet date. <br/></div><div style="font-size: 1px; margin-top: 18px; margin-bottom: 0px;"><div style="font-size: 1px; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"> </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">Recently Issued Accounting Standards </div></div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">2020-06,</div> Debt — Debt with Conversion and Other Options (Subtopic <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">470-20)</div> and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">815-40)</div> (“ASU <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">2020-06”)</div> to simplify accounting for certain financial instruments.

For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">non-cash</div> gain or loss on the statements of operations.

ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances. </div></div><div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The valuation hierarchy is composed of three levels.

On November 22, 2017, the Company consummated the Initial Public Offering of 6,000,000 units (the “Units” and, with respect to the common stock included in the Units being offered, the “Public Shares”), generating gross proceeds of $60,000,000, which is described in Note 3.

The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding taxes payable on income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The stockholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account ($10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations).

If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, a stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or other legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor, officers and directors (the “Initial Stockholders”) have agreed (a) to vote their Founder’s Shares (as defined in Note 5), Placement Shares (as defined in Note 4) and any Public Shares held by them in favor of approving a Business Combination and (b) not to convert any Founder’s Shares, Placement Shares and any Public Shares held by them in connection with a stockholder vote to approve a Business Combination or sell any such shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. </div></div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company initially had until November 22, 2018 to complete a Business Combination. However, if the Company anticipated that it would not be able to consummate a Business Combination by November 22, 2018, the Company could extend the period of time to consummate a Business Combination up to two times, each by an additional three months. Pursuant to the terms of the Company’s Amended and Restated Certificate of Incorporation and the trust agreement entered into between the Company and Continental Stock Transfer & Trust Company on November 20, 2017, in order to extend the time available for the Company to consummate a Business Combination, the Sponsor or its affiliates or designees must deposit into the Trust Account $<div style="letter-spacing: 0px; top: 0px;;display:inline;">690,000</div> ($0.10 per share) for each three month extension, up to an aggregate of $1,380,000, or $0.20 per share, if the Company extends for the full six months, on or prior to the date of the applicable deadline. </div></div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On November 20, 2018, the period of time for the Company to consummate a Business Combination was extended for an additional three-month period ending on February 22, 2019, and, accordingly, $690,000 was deposited into the Trust Account. On February 21, 2019, the Company further extended the time required to consummate a Business Combination to May 22, 2019 and deposited an additional $690,000 into the Trust Account.

Additionally, the agreement entered into by AZ Property Partners specifically provides for two exceptions to the indemnity it has given: it will have no liability (1) as to any claimed amounts owed to a target business or vendor or other entity who has executed an agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, or (2) as to any claims for indemnification by the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that AZ Property Partners will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. </div></div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;">NASDAQ Notifications </div></div></div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">On January 4, 2021, the Company received a notice from the Staff stating that the Company’s failure to hold an annual stockholder meeting for the fiscal year ended December 31, 2019 by December 31, 2020, as required by Nasdaq Listing Rule 5820, could serve as an additional basis for delisting the Company’s securities from Nasdaq. The Company requested a hearing before the Panel to appeal the Staff’s determination with respect to both notices and the hearing was held on January 14, 2021. The Panel’s decision is subject to certain conditions, including that the Company will have completed its proposed business combination (the “Business Combination”) with NeuroRx on or before the Extended Date and that the combined company will have demonstrated compliance with all requirements for initial listing on Nasdaq.

As of March 31, 2021, approximately $120,000 of the amount on deposit in the Trust Account represented interest income, which is available to pay the Company’s tax obligations.

If a Business Combination is not consummated, all outstanding loans made by the Sponsor will be forgiven (see Note 6). In addition, BRAC agreed to loan the Company all funds necessary to pay expenses incurred in connection with and in order to consummate a business combination (the “Business Combination Expenses”) and such loans will be added to the Initial Notes (as defined in Note 6). If the Company does not consummate a Business Combination, all outstanding loans under the Notes will be forgiven, except to the extent of any funds held outside of the Trust Account after paying all other fees and expenses of the Company incurred prior to the date of such failure to consummate a Business Combination (see Note 6). </div><br/></div> <div style="font-size: 1px; margin-top: 12px; margin-bottom: 0px;"><div style="font-size: 1px; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;"> </div></div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: "times new roman"; font-size: 10pt; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company may raise additional capital through loans or additional investments from the Sponsor or its stockholders, officers, directors, or third parties.

Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to suspending the pursuit of a potential transaction. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Even if the Company can obtain sufficient financing or raise additional capital, it only has until May 24, 2021 (or as may be extended) to consummate a Business Combination.

The estimated fair value of the warrant liability is determined using Level 3 inputs. Inherent in a binomial options pricing model are assumptions related to expected share-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury <div style="white-space: nowrap; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">zero-coupon</div> yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero. </div> <div style="font-family: times new roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="display:inline;"><div style="font-family: "times new roman";
