Description of Organization and Business Operations	1. Description of Organization and Business Operations *Organization and General* PropTech Acquisition Corporation (the "Company") is a blank check company incorporated in Delaware on July 31, 2019 (date of inception). The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the "Business Combination"). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2020, the Company had not yet commenced any operations. All activities for the period from July 31, 2019 (date of inception) to March 31, 2020 related to the Company's formation and the Offering (as defined below), and since the closing of the Offering, the search for a prospective target for the initial Business Combination. The Company has selected December 31 as its fiscal year end. *Sponsor and Initial Public Offering* On November 26, 2019, the Company closed its initial public offering (the "Offering") of 17,250,000 units at $10.00 per unit (including the underwriters' full exercise of their over-allotment option) (the "Units" and, with respect to the shares of Class A common stock included in the Units, the "Public Shares") which is discussed in Note 3 and the sale of 5,700,000 warrants (each, a "Private Placement Warrant" and collectively, the "Private Placement Warrants") at a price of $1.00 per Private Placement Warrant in a private placement (the "Private Placement") to our sponsor, HC PropTech Partners I LLC (the "Sponsor") that closed simultaneously with the closing of the Offering (as described in Note 4). The Company has listed the Units, the Public Shares and the Public Warrants (as defined below) on the Nasdaq Capital Market ("Nasdaq"). *Trust Account* Upon the closing of the Offering on November 26, 2019, the Company deposited $172,500,000 ($10.00 per Unit) from the proceeds of the Offering and the sale of the Private Placement Warrants, into a trust account (the "Trust Account"), which were then invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any money market fund meeting certain conditions of Rule 2a-7 of the Investment Company Act of 1940, as amended (the "Investment Company Act"), which invest only in direct U.S, government treasury obligations until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company's stockholders, as described below. *Initial Business Combination* The Company's management has broad discretion with respect to the specific application of the net proceeds of the Offering and sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. Nasdaq rules provide that the 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 (as defined below) (less any deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the signing a definitive agreement to enter 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. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide its holders of the outstanding Public Shares (the "public stockholders") with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholders meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which public stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company's Amended and Restated Certificate of Incorporation provides that, a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a "group" (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), will be restricted from seeking redemption rights with respect to 15% or more of the Public Shares without the Company's prior written consent. The public stockholders will be entitled to redeem their shares for a pro rata portion of the amount then in the Trust Account (initially $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 tax obligations). The per-share amount to be distributed to public stockholders who redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the representative of the underwriters (as discussed in Note 5). There will be no redemption rights upon the completion of a Business Combination with respect to the Company's warrants ("Warrants"). These shares of Class A common stock will be recorded at a redemption value and classified as temporary equity upon the completion of the Offering, in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 480 "Distinguishing Liabilities from Equity." If a stockholder vote is not required 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, offer such redemption pursuant to the tender offer rules of the Securities and Exchange Commission (the "SEC"), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. The Company's Sponsor has agreed (a) to vote its Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Offering in favor of a Business Combination, (b) not to propose an amendment to the Company's Amended and Restated Certificate of Incorporation with respect to the Company's pre-Business Combination activities prior to the consummation of a Business Combination unless the Company provides dissenting public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares) and Private Placement Warrants (including underlying securities) into the right to receive cash from the Trust Account in connection with a stockholder vote to approve a Business Combination (or to sell any shares in a tender offer in connection with a Business Combination if the Company does not seek stockholder approval in connection therewith) or a vote to amend the provisions of the Amended and Restated Certificate of Incorporation relating to stockholders' rights of pre-Business Combination activity and (d) that the Founder Shares and Private Placement Warrants (including underlying securities) shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Sponsor will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the Offering if the Company fails to complete its Business Combination. If the Company is unable to complete a Business Combination within 18 months from the closing of the Offering, or May 26, 2021, (the "Combination Period"), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company's board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations to provide for claims of creditors and the requirements of applicable law. The representative of the underwriters has agreed to waive its rights to the deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Offering price per Unit ($10.00). The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company's indemnity of the underwriters of the Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations. None of the Company's officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. On January 9, 2020, the Company announced that, commencing on January 13, 2020, the holders of Units may elect to separately trade the shares of Class A common stock and warrants included in the Units. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The shares of Class A Common Stock and the warrants currently trade on the Nasdaq Capital Market under the symbols "PTAC" and "PTACW," respectively. The Units not separated will continue to trade on the Nasdaq Capital Market under the symbol "PTACU." *Liquidity* As of March 31, 2020, the Company had approximately $1.2 million of cash in its operating account, approximately $1.1 million of investment income held in the Trust Account available to pay franchise and income taxes (less up to $100,000 of such net interest to pay dissolution expenses), and working capital of approximately $1.1 million (including approximately $271,000 of tax obligations). Through March 31, 2020, the Company's liquidity needs have been satisfied through proceeds of $25,000 from the Sponsor for issuance of the Founder Shares (Note 4), $225,000 in loans from the Sponsor, and the net proceeds from the consummation of the Private Placement not held in the Trust Account. The balance of $225,000 in loans was paid in full upon the closing of the Offering on November 26, 2019. Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet the Company's needs through the earlier of the consummation of a Business Combination or one year from the date of this filing. Over this time period, the Company will use these funds for payment of general and administrative expenses as well as expenses associated with identifying and evaluating prospective Business Combination candidates, performing due diligence on prospective target businesses and structuring, negotiating and consummating a Business Combination.

Nasdaq rules provide that the 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 (as defined below) (less any deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination.
