Exhibit 10.3


 


STOCK ESCROW AGREEMENT


 


This STOCK ESCROW AGREEMENT, dated as of March 2,
2021 (“Agreement”), is by and among Roth CH Acquisition III Co., a Delaware corporation (the “Company”),
the initial securityholders listed on Exhibit A attached hereto (each, an “Initial Securityholder” and
collectively the “Initial Securityholders”) and Continental Stock Transfer & Trust Company, a New York corporation
(the “Escrow Agent”).


 


WHEREAS, the Company has entered into an Underwriting
Agreement, dated as of March 2, 2021 (“Underwriting Agreement”), with Roth Capital Partners, LLC and Craig-Hallum
Capital Group LLC, acting jointly as the representatives of the underwriters (collectively, the “Underwriters”), pursuant
to which, among other matters, the Underwriters have agreed to purchase 10,000,000 units (“Units”) of the Company,
plus an additional 1,500,000 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 (“Common Stock”), and one-quarter of one redeemable warrant,
each whole warrant entitling its holder to purchase one share of Common Stock at an exercise price of $11.50 per full share of
Common Stock, both as more fully described in the Company’s final Prospectus, dated March 2, 2021 (“Prospectus”),
comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-252044) under the Securities
Act of 1933, as amended (“Registration Statement”), declared effective on March 2, 2021 (“Effective Date”).


 


WHEREAS, the Initial Securityholders 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 in Exhibit A attached hereto (collectively “Escrow Securities”), in escrow
as hereinafter provided.


 


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


 


IT IS AGREED:


 


1.             Appointment
of Escrow Agent. The Company and the Initial Securityholders hereby appoint the Escrow Agent to act in accordance with and
subject to the terms of this Agreement with authority and power to transfer the Escrow Securities, and the Escrow Agent hereby
accepts such appointment and agrees to act in accordance with and subject to such terms without the need for any further guaranteed
share power from the Initial Securityholders.


 


2.             Deposit
of Escrow Securities. On or prior to the Effective Date, the Escrow Securities shall have been issued to each of the Initial
Securityholders in book entry representing such Initial Securityholder’s respective Escrow Securities, to be held and disbursed
subject to the terms and conditions of this Agreement. Each of the Initial Securityholders acknowledges that such Initial Securityholder’s
Escrow Securities is legended to reflect the deposit of such Escrow Securities under this Agreement.


 


3.             Disbursement
of the Escrow Securities.


 


3.1           The
Escrow Agent shall hold the Insider Shares during the period (the “Insider Shares Escrow Period”) commencing on the
date hereof and (i) for 50% of the Insider 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 Insider
Shares, ending six months after the date of the consummation of a Business Combination. The Insider Shares shall be released upon
notice to the Escrow Agent by any Initial Securityholder or the Company that the foregoing requirements have been met. The Company
shall promptly provide written notice of the consummation of a Business Combination to the Escrow Agent. Upon completion of the
Insider Shares Escrow Period, the Escrow Agent shall disburse such amount of each Initial Securityholder’s Insider Shares
to such Initial Securityholder; 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 Insider Shares Escrow Period, then the Escrow Agent shall promptly
destroy the certificates representing the Insider Shares; provided further, however, that if, subsequent to the Company’s
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 written 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 Insider
Shares to the Initial Securityholders. The Escrow Agent shall have no further duties hereunder after the disbursement or cancellation
of the Insider Shares in accordance with this Section 3.


 



    


     


    




 


3.2           Notwithstanding
Section 3.1, if the Underwriters do not exercise their over-allotment option to purchase an additional 1,500,000 Units of
the Company in full within 45 days of the date of the Prospectus (as described in the Underwriting Agreement), the Initial Securityholders
agree that the Escrow Agent shall return to the Company for cancellation, at no cost, the number of Insider Shares held by each
such holder determined by multiplying (a) the product of (i) 375,000 multiplied by (ii) a fraction, (x) the
numerator of which is the number of Insider Shares held by each such holder, and (y) the denominator of which is the total
number of Insider Shares, by (b) a fraction, (i) the numerator of which is 1,500,000 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
1,500,000. The Company shall promptly provide written 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.
The Initial Securityholders hereby irrevocably constitute and appoint Escrow Agent to transfer the said Insider Shares on the books
of the Company with full power of substitution in the premises.


 


4.             Rights
of Initial Securityholders in Escrow Securities.


 


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


 


4.2           Dividends
and Other Distributions in Respect of the Escrow Securities. During the Escrow Periods, all dividends payable in cash with
respect to the Escrow Securities shall be paid to the Initial Securityholders, but all dividends payable in shares 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 Securities” shall be deemed to include the Non-Cash Dividends distributed thereon,
if any.


 


4.3           Restrictions
on Transfer. During the Escrow Periods, the only permitted transfers of the Escrow Securities will be for transfers (i) to
any persons (including their affiliates and stockholders) participating in the private placement of the private units and the Company’s

and employees, (iii) if an Initial Securityholder is an entity, as a distribution to its, partners, stockholders or members
upon its liquidation, (iv) by bona fide gift to a member of the Initial Securityholder’s immediate family or to a trust,

(vii) by certain pledges to secure obligations incurred in connection with purchases of the Company’s securities, (viii) by
private sales at prices no greater than the price at which the Escrow Securities were originally purchased, or (ix) to the
Company for cancellation in accordance with Section 3.2 above or in connection with the consummation of a Business Combination,
in each case, (except for clause (ix) or with the Company’s 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 Securityholder transferring the Escrow Securities.


 


4.4           Insider
Letters. Each of the Initial Securityholders has executed a letter agreement with the Company, dated as of the date hereof,
and the form of which is filed as an exhibit to the Registration Statement (“Insider Letter”), respecting the rights
and obligations of such Initial Securityholder in certain events, including but not limited to the liquidation of the Company.

of any information therein contained) which is believed by the Escrow Agent 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

Assurances. From time to time on and after the date hereof, the Company and the Initial Securityholders shall deliver or cause

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