Capitalized terms used and not otherwise defined herein shall have the meanings given to such terms in the Merger Agreement.

1. As a condition to the obligations of Acquiror, Merger Sub and the Company to consummate the Merger, the undersigned hereby agrees that from the date hereof until the 180^th day after the Closing (the “Lock-Up Period”), the undersigned will not: (x) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder (the “Exchange Act”), with respect to (i) shares of Acquiror Common Stock received pursuant to the Merger Agreement, (ii) any outstanding share of Acquiror Common Stock or any other equity security (including the shares of Acquiror Common Stock issued or issuable upon the exercise of any other equity security) of Acquiror received in connection with the transactions contemplated by the Merger Agreement, and (iii) any other equity security of Acquiror issued or issuable with respect to any such share of Acquiror Common Stock by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (such shares, collectively, the “Lock-Up Securities”), (y) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Lock-Up Securities, in cash or otherwise, or (z) publicly announce any intention to effect any transaction specified in clause (x) or (y) (any of the foregoing described in clauses (x), (y) or (z), a “Transfer”), provided that the foregoing shall not apply to any Transfer of any Acquiror Common Stock or other securities convertible into or exercisable or exchangeable for Acquiror Common Stock acquired in open market transactions after the Closing (as defined in the Merger Agreement); provided, however, that no such transaction is required to be, or is, publicly announced (whether on Form 4, Form 5 or otherwise, other than a required filing on Schedule 00X, 00X, 00X/X, 13G or 13G/A) during the Lock-Up Period. Furthermore, Section 1 shall not apply to the entry, by the undersigned, at any time after the Closing, of any trading plan providing for the sale of shares of Acquiror Common Stock by the undersigned, which trading plan meets the requirements of Rule 10b5-1(c) under the Exchange Act; provided, however, that such plan does not provide for, or permit, the sale of any Acquiror Common Stock during the Lock-Up Period and no public announcement or filing is voluntarily made or required regarding such plan during the Lock-Up Period.

2. The undersigned hereby (a) authorizes Acquiror during the Lock-Up Period to cause its transfer agent for the Lock-Up Securities to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Lock-Up Securities for which the undersigned is the record holder and, (b) in the case of Lock-Up Securities for which the undersigned is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Lock-Up Securities, in each case of clauses (a) and (b), if such transfer would constitute a violation or breach of this Agreement. Acquiror agrees to instruct its transfer agent to remove any stop transfer restrictions on the stock register and other records related to the Lock-Up Securities promptly upon the expiration of the Lock-Up Period. If any Transfer is made or attempted contrary to the provisions of this Agreement, such purported Transfer shall be null and void ab initio.

3. During the Lock-Up Period, each certificate evidencing any Lock-Up Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [    ], 2021, BY AND BETWEEN PROPERTY SOLUTIONS ACQUISITION CORP. (“ACQUIROR”) AND THE HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY ACQUIROR TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

4. Notwithstanding the foregoing, the undersigned may sell or otherwise transfer Lock-Up Securities during the undersigned’s lifetime or on death (or, if the undersigned is not a natural person, during its existence): (i) to Acquiror’s or the undersigned’s officers, directors, partners, members or their respective affiliates or to the undersigned’s affiliates; (ii) if the undersigned is not a natural person, to its stockholders, partners or members upon its liquidation; (iii) by bona fide gift to any immediate family members (including spouses, significant others, lineal descendants and ascendants (including adopted and step children and parents of such person)), brothers and sisters (including half-sibling and step-siblings) of the undersigned or the undersigned’s spouse or siblings (collectively, “Family Members”) or to a family trust, established for the exclusive benefit of the undersigned, its equity holders or any of their respective Family Members for estate planning purposes or to any charitable organization; (iv) by virtue of laws of descent and distribution upon death of the undersigned; (v) pursuant to a court order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union[; or (vi) to any of the ultimate beneficiaries of the Pre-A Convertible Debt set forth in Schedule A hereto or any of their designees for nominal consideration simultaneously with such beneficiaries of the Pre-A Convertible Debt entering into a separate agreement to cancel debt owed to such beneficiaries by Beijing Bairui Culture and Media Co., Ltd. in a manner permitted under Chinese law.];¹ provided, however, that except with Acquiror’s prior written consent, any such sale or transfer shall be conditioned upon entry by such transferees into a written agreement, addressed to Acquiror, agreeing to be bound by these transfer restrictions and the other terms and conditions of this Agreement.
