Exhibit 10.6

STOCK ESCROW AGREEMENT

STOCK ESCROW AGREEMENT, dated as of [●], 2021 (“Agreement”), by and among Astrea Acquisition Corp., a Delaware corporation (“Company”), the stockholder of the Company listed on Exhibit A hereto (the “Sponsor”) and Continental Stock Transfer & Trust Company, a New York limited purpose trust company (“Escrow Agent”).

WHEREAS, the Company was formed for the purpose of completing a merger, stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination (a “Business Combination”) with one or more businesses or entities.

WHEREAS, the Sponsor purchased an aggregate of 4,312,500 shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”) in a private placement;

WHEREAS, the Company has entered into an Underwriting Agreement, dated [●], 2021 (“Underwriting Agreement”), with EarlyBirdCapital, Inc. (the “Representative”) acting as representative of the several underwriters (collectively, the “Underwriters”), pursuant to which, among other matters, the Underwriters have agreed to purchase 15,000,000 units (“Units”) of the Company, plus up to an additional 2,250,000 Units if the Representative exercises the over-allotment option in full. Each Unit consists of one share of Common Stock and one-half of one warrant (“Warrant”), each whole Warrant to purchase one share of Common Stock, all as more fully described in the Company’s final Prospectus, dated [●], 2021 (“Prospectus”) comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-252010) under the Securities Act of 1933, as amended (“Registration Statement”), declared effective on [●], 2021 (“Effective Date”).

WHEREAS, the Sponsor has agreed as a condition of the sale of the Units to deposit its shares of Common Stock of the Company in escrow as hereinafter provided.

WHEREAS, the Company and the Sponsor desire that the Escrow Agent accept the shares of Common Stock, in escrow, to be held and disbursed as hereinafter provided.

IT IS AGREED:

1. Appointment of Escrow Agent. The Company and the Sponsor hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms.

2. Deposit of Shares. On or before the Effective Date, the Sponsor’s shares of Common Stock set forth on Exhibit A hereto shall be deposited in escrow, to be held and disbursed subject to the terms and conditions of this Agreement. The Sponsor acknowledges that the shares deposited in escrow will be legended to reflect the deposit of such shares under this Agreement.

3. Disbursement of the Escrow Shares.

3.1 If the over-allotment option to purchase all or a portion of the additional 2,250,000 Units of the Company is not exercised in full within 45 days of the date of the Prospectus (as described in the Underwriting Agreement), the Sponsor agrees that the Escrow Agent shall return to the Company for cancellation, at no cost, the number of shares of Common Stock determined by multiplying 562,500 by a fraction, (i) the numerator of which is 2,250,000 minus the number of shares of Common Stock included in the Units purchased by the Underwriters upon the exercise of the over-allotment option, and (ii) the denominator of which is 2,250,000. The Company shall promptly provide notice to the Escrow Agent of the expiration or termination of the over-allotment option and the number of Units, if any, purchased by the Underwriters in connection with the exercise thereof.

3.2 Except as otherwise set forth herein, the Escrow Agent shall hold the shares remaining after any cancellation required pursuant to Section 3.1 above (such remaining shares to be referred to herein as the “Escrow Shares”) until the earlier of (i) the six-month anniversary of the date of the consummation of the Company’s initial Business Combination and (ii) the date on which the closing price of the Common Stock equals or exceeds $12.50 per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any 20 trading days within a 30-trading day period following 150 days after the consummation of the initial Business Combination, or earlier if, subsequent to the initial Business Combination, the Company consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property (such period of time during which the Escrow Shares are held in escrow, the “Escrow Period”). Upon the achievement of any of the conditions set forth above, the Company shall promptly provide notice to the Escrow Agent, in form reasonably acceptable to the Escrow Agent. Upon completion of the Escrow Period, the Escrow Agent shall disburse such amount of each Sponsor’s Escrow Shares to the Sponsor. The Escrow Agent shall have no further duties hereunder after the disbursement of the Escrow Shares in accordance with this Section 3.2.

3.3 Notwithstanding the provisions of Section 3.2, if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company’s Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and the Escrow Agent as trustee thereunder) is being liquidated, then the Escrow Agent shall deliver the certificates representing the Escrow Shares to the Sponsor promptly after the public stockholders are paid the liquidating distributions and shall have no further duties hereunder.

4. Rights of Sponsor in Escrow Shares.

4.1 Voting Rights as a Stockholder. Subject to the terms of the Insider Letter described in Section 4.4 hereof and except as herein provided, the Sponsor shall retain all of its rights as a stockholder of the Company as long as any shares are held in escrow pursuant to this Agreement, including, without limitation, the right to vote such shares.

4.2 Dividends and Other Distributions in Respect of the Escrow Shares. For as long as any shares are held in escrow pursuant to this Agreement, all dividends payable in cash with respect to the Escrow Shares shall be paid to the Sponsor, but all dividends payable in stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term “Escrow Shares” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.

4.3 Restrictions on Transfer. During the Escrow Period, the only permitted transfers of the Escrow Shares will be (i) to officers, directors, consultants or affiliates of the Sponsor or the Company, (ii) to the Sponsor’s stockholders, partners or members upon the Sponsor’s liquidation, (iii) by bona fide gift to a member of the Sponsor’s immediate family or to a trust, the beneficiary of which is a Sponsor or a member of a Sponsor’s immediate family for estate planning purposes, (iv) by virtue of the laws of descent and distribution upon death of a Sponsor, (v) pursuant to a qualified domestic relations order binding on a Sponsor, (vi) to the Company for no value for cancellation in connection with the consummation of a Business Combination or (vii) by private sales of the Escrow Shares made at or prior to the consummation of a Business Combination at prices no greater than the price at which the Escrow Shares were originally purchased; provided, however, that except for clause (vi) or with the Company’s prior written consent, such permitted transfers may be implemented only upon the respective transferee’s written agreement to be bound by the terms and conditions of this Agreement and of the Insider Letter signed by the Sponsor transferring the shares.

4.4 Insider Letter. The Sponsor has executed a letter agreement with the Company and the Representative, dated as of the date hereto, the form of which is filed as an exhibit to the Registration Statement (“Insider Letter”), respecting the rights and obligations of the Sponsor in certain events, including, but not limited to, the liquidation of the Company.

5. Concerning the Escrow Agent.

5.1 Good Faith Reliance. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith and in the exercise of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Escrow Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which is believed by the Escrow Agent in good faith to be genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto.

5.2 Indemnification. Subject to Section 5.8 below, the Escrow Agent shall be indemnified and held harmless by the Company from and against any expenses, including reasonable counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with any action, suit or other proceeding involving any claim which in any way, directly or indirectly, arises out of or relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses arising from the gross negligence, fraud or willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or disposition of the Escrow Shares or it may deposit the Escrow Shares with the clerk of any appropriate court or it may retain the Escrow Shares pending receipt of a final, non-appealable order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Escrow Shares are to be disbursed and delivered. The provisions of this Section 5.2 shall survive in the event the Escrow Agent resigns or is discharged pursuant to Sections 5.5 or 5.6 below.

5.3 Compensation. Subject to Section 5.8 below, the Escrow Agent shall be entitled to reasonable compensation from the Company for all services rendered by it hereunder. The Escrow Agent shall also be entitled to reimbursement from the Company for all reasonable expenses paid or incurred by it in the administration of its duties hereunder including, but not limited to, all counsel, advisors’ and agents’ fees and disbursements and all taxes or other governmental charges.

5.4 Further Assurances. From time to time on and after the date hereof, the Company and the Sponsor shall deliver or cause to be delivered to the Escrow Agent such further documents and instruments and shall do or cause to be done such further acts as the Escrow Agent shall reasonably request to carry out more effectively the provisions and purposes of this Agreement, to evidence compliance herewith or to assure itself that it is protected in acting hereunder.

5.5 Resignation. The Escrow Agent may resign at any time and be discharged from its duties as escrow agent hereunder by its giving the other parties hereto written notice and such resignation shall become effective as hereinafter provided. Such resignation shall become effective at such time that the Escrow Agent shall turn the Escrow Shares over to a successor escrow agent appointed by the Company and approved by the Representative, which approval will not be unreasonably withheld, conditioned or delayed. If no new escrow agent is so appointed within the 60-day period following the giving of such notice of resignation, the Escrow Agent may deposit the Escrow Shares with any court it reasonably deems appropriate in the State of New York.

5.6 Discharge of Escrow Agent. The Escrow Agent shall resign and be discharged from its duties as escrow agent hereunder if so requested in writing at any time by all of the other parties hereto; provided, however, that such resignation shall become effective only upon the appointment of a successor escrow agent selected by the Company and approved by the Representative, which approval will not be unreasonably withheld, conditioned or delayed.

5.7 Liability. Notwithstanding anything herein to the contrary, the Escrow Agent shall not be relieved from liability hereunder for its own gross negligence, fraud or willful misconduct.

5.8 Waiver. The Escrow Agent hereby waives any right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.
