Exhibit 10.3


 


STOCK ESCROW AGREEMENT


 


This STOCK ESCROW AGREEMENT,
dated as of _______, 2021 (“Agreement”), by and among MOUNTAIN CREST ACQUISITION CORP. V, a Delaware corporation (“Company”),
and the initial shareholders listed on the signature pages hereto (collectively, the “Initial Shareholders”) CONTINENTAL STOCK
TRANSFER & TRUST COMPANY, a New York corporation (“Escrow Agent”).


 


WHEREAS, the Company has entered
into an Underwriting Agreement, dated as of _______, 2021 (“Underwriting Agreement”), with Chardan Capital Markets LLC (“Chardan”)
acting as representative of the several underwriters (collectively, the “Underwriters”), pursuant to which, among other matters,
the Underwriters have agreed to purchase 6,000,000 units (“Units”) of the Company, plus an additional 900,000 Units if the
Underwriters exercise their over-allotment option in full. Each Unit consists of one share of common stock of the Company, par value
$0.0001 per share (the “Common Stock”) and one right to receive one-tenth (1/10) of a share of common stock upon the consummation
of an initial business combination, all as more fully described in the Company’s final Prospectus, dated _______, 20[  ]
(“Prospectus”), comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-260124) under the
Securities Act of 1933, as amended (“Registration Statement”), declared effective on _______, 2021 (“Effective Date”).


 


WHEREAS, the Initial Shareholders
have agreed as a condition of the sale of the Units to deposit their Insider Shares (as defined in the Prospectus), as set forth opposite
their respective names on Exhibit A attached hereto (collectively “Escrow Shares”), in escrow as hereinafter
provided.


 


WHEREAS, the Company and the
Initial Shareholders desire that the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed as hereinafter provided.


 


IT IS AGREED:


 


1. Appointment of
Escrow Agent. The Company and the Initial Shareholders 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 Escrow
Shares. On or prior to the date hereof, each of the Initial Shareholders delivered to the Escrow Agent certificates representing
such Initial Shareholder’s respective Escrow Shares, together with applicable share powers, to be held and disbursed subject to
the terms and conditions of this Agreement. Each of the Initial Shareholders acknowledges that the certificate representing such
Initial Shareholder’s Escrow Shares is legended to reflect the deposit of such Escrow Shares under this Agreement.


 






     


     


    

 


3. Disbursement of
the Escrow Shares.


 


3.1 The Escrow Agent shall
hold the Escrow Shares during the period (the “Escrow Period”) commencing on the date hereof and (i) for 50% of the Escrow
Shares, ending on the earlier of (x) six months after the date of the consummation of the Company’s initial business combination
(as described in the Registration Statement, hereinafter a “Business Combination”) and (y) the date on which the closing price
of the Common Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations)
for any 20 trading days within any 30-trading day period commencing after the Company’s initial Business Combination and (ii) for
the remaining 50% of the Escrow Shares, ending six months after the date of the consummation of an initial Business Combination. The Company
shall promptly provide notice of the consummation of a Business Combination to the Escrow Agent. Upon completion of the Escrow Period,
the Escrow Agent shall disburse such amount of each Initial Shareholder’s Escrow Shares (and any applicable share power) to such
Initial Shareholder; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company
is being liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy the certificates representing the
Escrow Shares; provided further, however, that if, within six months after the Company consummates an initial Business Combination, the
Company (or the surviving entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results
in all of the shareholders of such entity having the right to exchange their shares of Common Stock for cash, securities or other property,
then the Escrow Agent will, upon receipt of a notice executed by the Chairman of the Board, Chief Executive Officer or other authorized
officer of the Company, in form reasonably acceptable to the Escrow Agent, certifying that such transaction is then being consummated
or such conditions have been achieved, as applicable, release the Escrow Shares to the Initial Shareholders. The Escrow Agent shall
have no further duties hereunder after the disbursement or destruction of the Escrow Shares in accordance with this Section 3.1.


  


3.2 Notwithstanding Section
3.1, if the Underwriters do not exercise their over-allotment option to purchase an additional 900,000 Units of the Company in full within
45 days of the date of the Prospectus (as described in the Underwriting Agreement), the Initial Shareholders agree that the Escrow Agent
shall return to the Company for cancellation, at no cost, the number of Escrow Shares held by the Initial Shareholders listed on Exhibit
B determined by multiplying (a) the product of (i) 225,000 multiplied by (ii) a fraction, (x) the numerator of which is the number
of Escrow Shares held by each such holder, and (y) the denominator of which is the total number of Escrow Shares, by (b) a fraction, (i)
the numerator of which is 900,000 minus the number of shares of Common Stock purchased by the Underwriters upon the exercise of their
over-allotment option, and (ii) the denominator of which is 900,000. The Company shall promptly provide notice to the Escrow Agent of
the expiration or termination of the Underwriters’ over-allotment option and the number of Units, if any, purchased by the Underwriters
in connection with their exercise thereof.


 


4. Rights of Initial
Shareholders in Escrow Shares.


 


4.1 Voting Rights as
a Shareholder. Subject to the terms of the Insider Letters described in Section 4.4 hereof and except as herein provided, the
Initial Shareholders shall retain all of their rights as shareholders of the Company during the Escrow Period, including, without limitation,
the right to vote such shares.


 


4.2 Dividends and Other
Distributions in Respect of the Escrow Shares. During the Escrow Period, all dividends payable in cash with respect to the Escrow
Shares shall be paid to the Initial Shareholders, 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 (1) to the Company’s pre-IPO stockholders or their
respective affiliates, or to the Company’s offices, directors, advisors and employees, (2) if the Initial Shareholder is an entity,
as a distribution to its, partners, stockholders or members upon its liquidation, (3) by bona fide gift to a member of the Initial Shareholder’s
immediate family or to a trust, the beneficiary of which is the Initial Shareholder or a member of the Initial Shareholder’s immediate
family for estate planning purposes, (4) by virtue of the laws of descent and distribution upon death of the Initial Shareholder, (5)
pursuant to a qualified domestic relations order, (6) by certain pledges to secure obligations incurred in connection with purchases of
the Company’s securities, (7) by private sales at prices no greater than the price at which the Insider Shares were originally purchased
or (8) for the cancellation of up to 225,000 shares of Common Stock subject to forfeiture to the extent that the Underwriters’ over-allotment
is not exercised in full or in part or in connection with the consummation of our initial Business Combination, in each case (except for
clause 8 or with our prior consent) on the condition that such 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 (as defined below) signed by the
Initial Shareholder transferring the Escrow Shares.


 


4.4 Insider Letters. Each
of the Initial Shareholders has executed a letter agreement with Chardan and the Company, dated as indicated on Exhibit C hereto,
and the form of which is filed as an exhibit to the Registration Statement (“Insider Letter”), respecting the rights and obligations
of such Initial Shareholder in certain events, including but not limited to the liquidation of the Company.

the Escrow Shares with any court it reasonably deems appropriate.


 


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
