(a) The
Escrow Agent shall invest the Escrow Property in accordance with the written instructions provided to the Escrow Agent and signed by
the Company in such investments (i) as shall from time to time be selected by the Company and (ii) be investments the Escrow Agent is
able to hold. In the absence of written investment instructions from the Company, the Escrow Agent shall hold the Escrow Property un-invested,

(b) The
Escrow Agent is hereby authorized and directed to sell or redeem any such investments as it deems necessary to make any payments or distributions
required under this Escrow Agreement. The Escrow Agent shall have no responsibility or liability for any loss which may result from any
investment, including, without limitation, negative interest, or sale of investment made pursuant to this Escrow Agreement. The Escrow
Agent is hereby authorized, in making or disposing of any investment permitted by this Escrow Agreement, to deal with itself (in its
individual capacity) or with any one or more of its affiliates, whether it or any such affiliate is acting as agent of the Escrow Agent
or for any third person or dealing as principal for its own account. The Parties acknowledge that the Escrow Agent is not providing investment
supervision, recommendations, or advice.


 


(c) In
the event that market conditions are such that negative interest applies to amounts deposited with the Escrow Agent, the Company shall
be responsible for the payment of such interest and the Escrow Agent shall be entitled to deduct from amounts on deposit with it an amount
necessary to pay such negative interest. For the avoidance of doubt, the indemnification protections afforded to the Escrow Agent under
Section 3.1 of this Escrow Agreement shall cover any interest-related expenses (including, but not limited to, negative interest)
incurred by the Escrow Agent in the performance of its duties hereunder.


 


1.3. Disbursements.


 


(a) The
Escrowed Property shall be held by the Escrow Agent for the purpose of satisfying the initial $400,000 of the indemnification obligations
of the Company, with respect to the Escrow Property, pursuant to Section 3(p) of the Underwriting Agreement dated June [ ], 2021 by and
between the Company and the Underwriters, for a period of 12 months from the closing of the Offering. Disbursement of such Escrowed Property
upon a claim of indemnity pursuant to the terms of the Underwriting Agreement shall be determined by an independent third-party intermediary
(who shall have the requisite experience in determining indemnification claims) to be chosen by mutual written consent of the Company
and the Underwriters. If the Company and the Underwriters are unable to agree on such intermediary within 30 days upon a written claim
for indemnity by the Underwriters, such intermediary shall be a single arbitrator (with the requisite experience in determining indemnification
claims) selected by the American Arbitration Association’s New York office.


 


(b) In
the event that any litigation or proceeding arising out of any matter in connection with the Offering and the Underwriters acting in
its capacity as underwriters (which matter would be covered by the Company’s indemnification obligations under the Underwriting
Agreement) within 12 months following the Closing Date and in which the Company, the Underwriters, or the Escrow Property becomes the
subject of such litigation or proceeding, the Underwriters and the Company hereby authorize the Escrow Agent, at the Underwriters’
sole instruction upon Underwriters’ written no tice to the Escrow Agent if not otherwise so required, to release and deposit the
Escrow Property with the clerk of the court in which the litigation is pending for the purpose of indemnifying and defending the Underwriters
in such litigation and proceeding, and thereupon the Escrow Agent shall be relieved and discharged of any further responsibility with
regard thereto to the extent determined by any such court. The Company and the Underwriters further hereby authorize the Escrow Agent,
if it receives conflicting claims to any of the Escrow Property, is threatened with litigation in its capacity as escrow agent under
this Escrow Agreement, or if the Escrow Agent determines it is necessary to do so for any other reason relating to this Escrow Agreement
or the Offering, to interplead all interested parties in any court of competent jurisdiction and to deposit the Escrow Property with
the clerk of that court and thereupon the Escrow Agent shall be relieved and discharged of any further responsibility hereunder to the
parties from which they were received to the extent determined by such court.

all instances, if either (i) no claim for indemnity is made by the Underwriters during the 12-month period from the closing of the Offering
or (ii) it is finally determined that the Underwriters are not entitled to any disbursement (or any further disbursement, as the case
may be) of Escrow Property by the conclusion of the 12-month period from the closing of the Offering, the Escrow Agent shall disburse
to the Company the full balance of the Escrow Property then held by wire transfer of immediately available funds to an account designated
by the Company.


 


(d) In
the event that Escrow Agent makes any payment to any other party pursuant to this Escrow Agreement and for any reason such payment (or
any portion thereof) is required to be returned to the Escrow Account or another party or is subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to a receiver, trustee or other party under any bankruptcy or insolvency
law, other federal or state law, common law or equitable doctrine, then the recipient shall repay to the Escrow Agent upon written request
the amount so paid to it.


 


(e) The
Escrow Agent shall, in its sole discretion, comply with judgments or orders issued or process entered by any court with respect to the
Escrow Property, including without limitation any attachment, levy or garnishment, without any obligation to determine such court's jurisdiction
in the matter and in accordance with its normal business practices. If the Escrow Agent complies with any such judgment, order or process,
then Escrow Agent shall not be liable to either Party or any other person by reason of such compliance, regardless of the final disposition
of any such judgment, order or process.


 


(f) Each
Party understands and agrees that the Escrow Agent shall have no obligation or duty to act upon a Written Direction delivered to the
Escrow Agent for the disbursement of Escrow Property under this Escrow Agreement if such Written Direction is not (i) in writing, (ii)
signed by, in the case of Company, any individual designated by Company on Exhibit B-1 hereto or, in the case of Underwriters,
any individual designated by Underwriters on Exhibit B-2 hereto (in each case, each such individual an “Authorized Representative”
of such Party), and (iii) delivered to, and able to be authenticated by, the Escrow Agent in accordance with Section 1.5.


 


(g) Upon
request, the Escrow Agent will furnish monthly statements to each Party setting forth the activity in the Escrow Account.

any means chosen by the Escrow Agent.

1.4. Written
Direction and Other Instruction.


 


(a) With
respect to any Written Direction or any other notice, direction or other instruction required to be delivered by a Party to the Escrow
Agent under this Escrow Agreement, the Escrow Agent is authorized to follow and rely upon any and all such instructions given to it from
time to time if the Escrow Agent believes, in good faith, that such instruction is genuine and to have been signed by an Authorized Representative
of such Party. The Escrow Agent shall have no duty or obligation to verify that the person who sent such instruction is, in fact, a person
duly authorized to give instructions on behalf of a Party, other than to verify that the signature of the Authorized Representative on
any such instruction appears to be the signature of such person. Each Party acknowledges and agrees that it is fully informed of the
protections and risks associated with the various methods of transmitting instructions to the Escrow Agent, and that there may be more
secure methods of transmitting instructions other than the method selected by such Party. The Escrow Agent shall have no responsibility
or liability for any loss which may result from:


 


(i) any
action taken or not taken by the Escrow Agent in good faith reliance on any such signatures or instructions;


 


(ii) as
a result of a Party’s reliance upon or use of any particular method of delivering instructions to the Escrow Agent, including the
risk of interception of such instruction and misuse by third parties; or


 


(iii) any
officer or Authorized Representative of a Party named in an incumbency certificate, Exhibit B-1 or Exhibit B-2 delivered
hereunder prior to actual receipt by the Escrow Agent of a more current incumbency certificate or an updated Exhibit B-1 or Exhibit
B-2 and a reasonable time for the Escrow Agent to act upon such updated or more current certificate or Exhibit.


 


(b) Company
may, at any time, update Exhibit B-1 and Underwriters may, at any time, update Exhibit B-2 by signing and submitting to
the Escrow Agent an updated Exhibit. Any updated Exhibit shall not be effective unless the Escrow Agent countersigns a copy thereof.
The Escrow Agent shall be entitled to a reasonable time to act to implement any changes on an updated Exhibit.


 


1.5. Delivery
and Authentication of Written Direction.


(a) A
Written Direction must be delivered to the Escrow Agent by one of the delivery methods set forth in Section 4.3.


 


(b) Each
Party and the Escrow Agent hereby agree that the following security procedures will be used to verify the authenticity of a Written Direction
delivered by any Party to the Escrow Agent under this Escrow Agreement:


 


(i) The
Written Direction must include the name and signature of the person delivering the disbursement request to the Escrow Agent. The Escrow
Agent will check that the name and signature of the person identified on the Written Direction appears to be the same as the name and
signature of an Authorized Representative of such Party;


 


(ii) The
Escrow Agent will make a telephone call to an Authorized Representative of the Party purporting to deliver the Written Direction (which
Authorized Representative may be the same as the Authorized Representative who delivered the Written Direction) at any telephone number
for such Authorized Representative as set forth on Exhibit B-1 or Exhibit B-2, as applicable, to obtain oral confirmation
of delivery of the Written Direction. If the Written Direction is a joint written notice of the Parties, the Escrow Agent shall call
back an Authorized Representative of both of those Parties; and


 


(iii) If
the Written Direction is sent by email to the Escrow Agent, the Escrow Agent also shall review such email address to verify that it appears
to have been sent from an email address for an Authorized Representative of such Party as set forth on Exhibit B-1 or Exhibit
B-2, as applicable, or from an email address for a person authorized under Exhibit B-1 or Exhibit B-2, as applicable,
to email a Written Direction to the Escrow Agent on behalf of the Authorized Representative).

(c) Each
Party acknowledges and agrees that given its particular circumstances, including the nature of its business, the size, type and frequency
of its instructions, transactions and files, internal procedures and systems, the alternative security procedures offered by the Escrow
Agent and the security procedures in general use by other customers and banks similarly situated, the security procedures set forth in
this Section 1.5 are a commercially reasonable method of verifying the authenticity of a payment order in a Written Direction.


 


(d) The
Escrow Agent is authorized to execute, and each Party expressly agrees to be bound by any payment order in a Written Direction issued
in its name (and associated funds transfer) (i) that is accepted by the Escrow Agent in accordance with the security procedures set forth
in this Section 1.5, whether or not authorized by such Party and/or (ii) that is authorized by or on behalf of such Party or for which
such Party is otherwise bound under the law of agency, whether or not the security procedures set forth in this Section 1.5 were followed,
and to debit the Escrow Account for the amount of the payment order. Notwithstanding anything else, the Escrow Agent shall be deemed
to have acted in good faith and without negligence, gross negligence or misconduct if the Escrow Agent is authorized to execute the payment
order under this Section 1.5. Any action taken by the Escrow Agent pursuant to this Section 1.5 prior to the Escrow Agent’s actual
receipt and acknowledgement of a notice of revocation, cancellation or amendment of a Written Direction shall not be affected by such
notice of revocation, cancellation or amendment of a Written Direction.


 


(e) The
security procedures set forth in this Section 1.5 are intended to verify the authenticity of payment orders provided to the Escrow Agent
and are not designed to, and do not, detect errors in the transmission or content of any payment order. The Escrow Agent is not responsible
for detecting an error in the payment order, regardless of whether either Party believes the error was apparent, and the Escrow Agent
is not liable for any losses arising from any failure to detect an error.


 


(f) When
instructed to credit or pay a party by both name and a unique numeric or alpha-numeric identifier (e.g. ABA number or account number),
the Escrow Agent, and any other banks participating in the funds transfer, may rely solely on the unique identifier, even if it identifies
a party different than the party named. Each Party agrees to be bound by the rules of any funds transfer network used in connection with
any payment order accepted by the Escrow Agent hereunder.


 


(g) The
Escrow Agent shall not be obliged to make any payment requested under this Escrow Agreement if it is unable to validate the authenticity
of the request by the security procedures set forth in this Section 1.5. The Escrow Agent’s inability to confirm a payment order
may result in a delay or failure to act on that payment order. Notwithstanding anything else in this Escrow Agreement, the Escrow Agent
shall not be required to treat a payment order as having been received until the Escrow Agent has authenticated it pursuant to the security
procedures in this Section 1.5 and shall not be liable or responsible for any losses arising in relation to such delay or failure to
act.


 


1.6. Income
Tax Allocation and Reporting.


 


(a) Each
Party agrees that, for tax reporting purposes, the Escrow Property shall be deemed to be the property of [Purchaser/Seller] and
all interest and other income from investment of the Escrow Property shall, as of the end of each calendar year and to the extent required
by the Internal Revenue Service, be reported as having been earned by such Party, whether or not such income was disbursed during such
calendar year. Notwithstanding anything to the contrary herein, the Escrow Agent shall have no duty to prepare or file any Federal or
state tax report or return with respect to the Escrow Property, except for the delivery and filing of tax information reporting forms
required to be delivered and filed with the Internal Revenue Service. With respect to the preparation, delivery and filing of such required
tax information reporting forms and all matters pertaining to the reporting of earnings on the Escrow Property, the Escrow Agent shall
be entitled to request and receive written instructions from [Purchaser/Seller], and the Escrow Agent shall be entitled to rely
conclusively and without further inquiry on such written instructions. With respect to any other payments made under this Escrow Agreement,
the Escrow Agent shall not be deemed the payer and shall have no responsibility for performing tax reporting. The Escrow Agent’s
function of making such payments is solely ministerial and upon express direction of the Parties.

identification numbers by furnishing appropriate forms W-9 or W-8 and such other forms and documents that the Escrow Agent may request.

be required by the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, to withhold a portion of any
interest or other income earned on the investment of the Escrow Property.


 


(c) To
the extent that the Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of the
Escrow Property, the Escrow Agent shall satisfy such liability to the extent possible from the Escrow Property. The Parties, jointly
and severally, hereby indemnify, defend and hold the Escrow Agent harmless from and against any tax, late payment, interest, penalty
or other cost or expense that may be assessed against the Escrow Agent on or with respect to the Escrow Property and the investment thereof
unless such tax, late payment, interest, penalty or other expense was finally adjudicated to have been directly caused by the gross negligence
or willful misconduct of the Escrow Agent. The indemnification provided by this Section 1.6(c) is in addition to the indemnification
provided in Section 3.1 and shall survive the resignation or removal of the Escrow Agent and the termination of this Escrow Agreement.

Property in accordance with Section 1.3 (Disbursements) and this Escrow Agreement shall be of no further force and effect, except that

4.4. Governing
Law. This Escrow Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard

4.5. Venue. 
Each Party and the Escrow Agent hereby consent to the exclusive personal jurisdiction of the courts located in New Castle County in
the State of Delaware in the event of a dispute arising out of or under this Escrow Agreement. Each Party and the Escrow Agent hereby
irrevocably waives any objection to the laying of the venue of any suit, action or proceeding and irrevocably submits to the exclusive
jurisdiction of such court in such suit, action or proceeding.


 


4.6. Entire
Agreement. This Escrow Agreement and the exhibits hereto set forth the entire agreement and understanding of the parties related
to the Escrow Property and supersedes all prior agreements and understandings, oral or written. If a court of competent jurisdiction
declares a provision invalid, it will be ineffective only to the extent of the invalidity, so that the remainder of the provision and
Escrow Agreement will continue in full force and effect. In the event of any direct conflict of the terms of this Escrow Agreement with
the terms of the Underwriting Agreement, as with respect to the rights of the Company and Underwriters, the terms of the Underwriting
Agreement shall control and prevail; provided, in no event shall the Escrow Agent be bound by the terms of the Underwriting
Agreement. This Escrow Agreement is not intended to confer upon any person other than the parties hereto any rights or remedies.


 


4.7. Amendment.
This Escrow Agreement may be amended, modified, supplemented, superseded, rescinded, or canceled only by a written instrument executed
by the Parties and the Escrow Agent; provided that Exhibit B-1 or Exhibit B-2, as applicable, may be amended at any time
in accordance with Section 1.4.


 


4.8. Waivers.
The failure of any party to this Escrow Agreement at any time or times to require performance of any provision under this Escrow Agreement
shall in no manner affect the right at a later time to enforce the same performance. A waiver by any party to this Escrow Agreement of
any such condition or breach of any term, covenant, representation, or warranty contained in this Escrow Agreement, in any one or more
instances, shall neither be construed as a further or continuing waiver of any such condition or breach nor a waiver of any other condition
or breach of any other term, covenant, representation, or warranty contained in this Escrow Agreement.


 


4.9. Interpretation.
Section headings of this Escrow Agreement have been inserted for convenience of reference only and shall in no way restrict or otherwise
modify any of the terms or provisions of this Escrow Agreement. Unless otherwise indicated by the context, the singular shall include
the plural and the plural shall include the singular. Any references to an Exhibit is a reference to an Exhibit of this Escrow Agreement.

of counterparts may occur by manual signature, electronic signature, facsimile signature, manual signature transmitted by means of facsimile
transmission or manual signature contained in an imaged document attached to an email transmission, and any such execution that is not

in accordance with the foregoing shall be deemed an original, with all such counterparts together constituting one and the same instrument.
The exchange of executed copies of this Escrow Agreement or of executed signature pages to this Escrow Agreement by electronic transmission,
facsimile transmission or as an imaged document attached to an email transmission shall constitute effective execution and delivery hereof.
Any copy of this Escrow Agreement which is fully executed and transmitted in accordance with the terms hereof may be used for all purposes
in lieu of a manually executed copy of this Escrow Agreement and shall have the same legal effect, validity and enforceability as if
executed by manual signature.
