the Original Agreement in accordance with the terms hereof (the Original Agreement, as amended and restated by the A&R Agreement,

NOW
THEREFORE, IN CONSIDERATION of the foregoing recitals, the mutual covenants and agreements hereinafter set forth and other good and valuable
consideration, the receipt and sufficiency of which are acknowledged hereby, the Borrower and Lender hereto, intending legally to be

1.
Commitment. As of the date hereof, the Lender has made loans to the Borrower in the aggregate principal amount of $507,500.00.
Subject to and in accordance with the provisions of this Agreement, Lender agrees to make additional disbursements of a loan (collectively,

Borrower upon the terms and conditions expressed in this Agreement in an aggregate principal amount of not to exceed One Million Seven
Hundred Fifty Seven Thousand Five Hundred and no/100 Dollars ($1,757,500.00) (which includes the $507,500.00 that is currently outstanding).
The Borrower (i) shall borrow, so long as the Effective Date has occurred by such time, Five Hundred Thousand and no/100 Dollars ($500,000.00)
of the One Million Two Hundred Fifty Thousand and no/100 Dollars ($1,250,000.00) in remaining commitment on and after June 15, 2022 but
on or before June 20, 2022, and (ii) may borrow up to Seven Hundred Fifty Thousand and no/100 Dollars ($750,000.00) of the One Million
Two Hundred Fifty Thousand and no/100 Dollars ($1,250,000.00) in remaining commitment on and after January 14, 2023 but prior to December
30, 2023. The Lender’s commitment to make such disbursements shall terminate on the earlier of (a) December 30, 2023 and (b) the

however that the Lender’s commitment shall be reduced by Five Hundred Thousand and no/100 Dollars ($500,00.00) of the Borrower
fails to borrow such amount by June 20, 2022 pursuant to clause (i) above of this paragraph 1. All proceeds of the Loan shall be used
by Borrower in the normal course of Borrower’s business, provided that no Loan proceeds shall be used to make any payments,
dividends, or other disbursements to any owners of Borrower or family members thereof other than, to the extent permitted under the terms
and provisions of the Acquisition Agreement, the salaries of the owners of the Borrower in the ordinary course of business and in the
amounts paid to such owners as of the date of this Agreement. To make a borrowing under the Loan, the Borrower shall provide written
notice to the Lender requesting such borrowing at least one (1) business day prior to the making of such borrowing. In no event shall
the aggregate principal amount of all borrowing made (i) under this Agreement exceed One Million Seven Hundred Fifty Seven Thousand and
no/100 Dollars ($1,757,500.00) and (ii) under this Agreement on and after the Effective Date exceed One Million Two Hundred Fifty Thousand
and no/100 Dollars ($1,250,000.00). All amounts borrowed hereunder shall be due and payable, together with all accrued and unpaid interest

2.
The Note. Borrower’s obligation to pay the principal on the Loan shall be evidenced by an Amended and Restated Secured Promissory
Note (as the same may be amended, restated, supplemented or modified from time to time, the “Note”), substantially
in the form attached hereto as Exhibit A, the terms of which are incorporated herein by this reference. The Loan may be repaid
in whole or in part at any time, without penalty or premium, as provided in the Note. The Note shall bear interest and such interest
shall be payable as provided therein.

 

3.
Security. Borrower’s obligations under this Agreement, the Note and each other agreement, instrument and document delivered
in connection herewith (collectively, as the same may be amended, restated, supplemented or modified from time to time, the “Credit
Documents”) shall be secured by a binding lien on the collateral of Borrower set forth and described in Exhibit B attached
hereto and made a part hereof (the “Collateral”) created by this Agreement. In addition to any other remedies which
Lender has hereunder or by law, upon default, Lender shall have the right to enforce the Credit Documents. The Borrower together with
any other person who grants a lien to secure, or who guarantees, the Obligations (as defined below) are referred to in the Credit Documents
as the “Loan Parties” and each a “Loan Party”.

 

4.
Security Interest and Collateral Covenants.

 

(a)
To secure the prompt payment and performance in full when due, whether by lapse of time, acceleration, mandatory prepayment or otherwise,
of the Loan and Note and all other Obligations (as defined below), Borrower hereby grants to Lender, for itself and for the benefit of
its successors and assigns, a continuing security interest in, and a right to set off against, any and all right, title and interest
of Borrower in and to the Collateral. “Obligations” means (a) all advances to, and debts, liabilities, obligations,
covenants and duties of, any Loan Party arising under any Credit Document or otherwise with respect to the Loan or Note, whether direct
or indirect (including those acquired by assumption), absolute or contingent, due or to become due, now existing or hereafter arising
and including interest and fees that accrue after the commencement by or against any Loan Party or any Affiliate thereof of any proceeding
under any Debtor Relief Laws naming such Person as the debtor in such proceeding, regardless of whether such interest and fees are allowed
claims in such proceeding. “Affiliate” means, with respect to any Person, any Person that directly or indirectly through
one or more intermediaries, controls, or is controlled by, or is under common control with, such first Person. A Person shall be deemed
to control another Person (“Control” or “Controlling”) if such first Person possesses, directly
or indirectly, the power to direct, or cause the direction of, the management and policies of the second Person, whether through the
ownership of voting securities, common directors, trustees or officers, the power to appoint common directors, trustees or officers by
contract or otherwise. “Debtor Relief Laws” means the Bankruptcy Code of the United States, and all other liquidation,
conservatorship, bankruptcy, assignment for the benefit of creditors, moratorium, rearrangement, receivership, insolvency, reorganization,

of creditors generally. “Person” means an individual, a corporation, a partnership, an association, a trust or any

payable, and cash balances and (ii) deliver to Lender copies of customers’ invoices or the equivalent, original shipping and delivery
receipts or other proof of delivery, customers’ statements, the original copy of all documents, including, without limitation,
repayment histories and present status reports, relating to accounts and such other documents and information relating to the accounts
as Lender shall specify.

 

(c)
The Borrower shall defend its title in and to the Collateral and shall defend the security interest of Lender in the Collateral against
the claims and demands of all persons, other than Lender and its successors and assigns and other than those Liens described in Section
6 herein.

 

(d)
The Borrower shall (i) protect and preserve all properties material to its business, and maintain all tangible property in good and workable
condition in all material respects, with reasonable allowance for wear and tear, and (ii) from time to time make or cause to be made
all needed and appropriate repairs, renewals, replacements, and additions to such properties necessary for the conduct of its business.

 

(e)
Borrower shall not change the location of its place of business (or, if it has more than one place of business, its chief executive office)
or the place where it keeps its books and records relating to the Collateral or change its name, identity, corporate structure or jurisdiction
of organization without giving Lender at least 30 days’ prior written notice thereof.

 

(f)
To the extent allowed by law, neither Lender nor any of its officers, directors, employees or agents shall be liable or responsible in
any way for the safekeeping of any Collateral or for any act or failure to act with respect to the Collateral, or for any loss or damage
thereto or any diminution in the value thereof, or for any act by any other person. In the case of any instruments and chattel paper
included within the Collateral, Lender shall have no duty or obligation to preserve rights against prior parties. The Loan shall not
be affected by any failure of Lender to take any steps to perfect its security interests or to collect or realize upon the Collateral,
nor shall loss of or damage to the Collateral release Borrower from any of the obligations.

 

(g)
The Borrower shall perform, at its expense, all actions requested by Lender at any time to perfect, maintain, protect and enforce Lender’s
security interest in the Collateral. The Borrower hereby agrees that the Lender may file Uniform Commercial Code financing statements
in any jurisdiction and such financing statements may describe the Collateral as “all assets” or it may contain any other
description. The Borrower shall also execute upon request and copyright, patent and/or trademark security agreement requested by Lender.
Lender may make any filings with the U.S. Patent and Trademark Office and the U.S. Copyright Office it determines is necessary to protect
its security interest in the Intellectual Property (as defined in Exhibit B).

of the Collateral and in this connection review, audit and make extracts from all records and files related to any of the Collateral.

behalf of Borrower.

13.
Modifications; Waiver. No provision of this Agreement may be amended, supplemented, waived or otherwise modified except by a written
agreement mutually executed by Borrower and Lender. Neither any failure nor any delay by Borrower or Lender in exercising any right,
power or privilege under this Agreement or any other Credit Document will operate as a waiver of such right, power or privilege, and

or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable law, (a) no waiver
that may be given by Borrower or Lender will be applicable except in the specific instance for which it is given, and (b) no notice to

16.
Maximum Interest. Notwithstanding anything to the contrary contained in any Credit Document, the interest paid or agreed to be
paid under the Credit Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum
Rate”). If the Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied
to the principal of the Loan or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted
for, charged, or received by the Lender exceeds the Maximum Rate, Lender may, to the extent permitted by applicable law, (a) characterize
any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects
thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated
term of the Obligations hereunder.

		3.	Miscellaneous Provisions.

 

		3.1	Effectiveness of the Amendment. Each of the parties hereto acknowledges and agrees that the effectiveness
of this Agreement shall be expressly subject to the occurrence of the Mergers and substantially contemporaneous occurrence of the SPAC
Merger Effective Time and shall automatically be terminated and shall be null and void if the Business Combination Agreement shall be
terminated for any reason.

 

    	 	3	 

     

    

 

		3.2	Successors. All the covenants and provisions of this Agreement by or for the benefit of Holdco,
the Company or the Warrant Agent shall bind and inure to the benefit of their respective successors and assigns.

 

		3.3	Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement
shall be governed in all respects by the laws of the State of New York. Subject to applicable law, each of Holdco and the Company hereby
agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced
in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits
to such jurisdiction, which jurisdiction shall be exclusive forum for any such action, proceeding or claim. Each of Holdco and the Company
hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing,
the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other
claim for which the federal district courts of the United States of America are the sole and exclusive forum.

 

Any person or entity
purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented to the forum provisions
in this Section 3.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court
other than a court located within the State of New York or the United States District Court for the Southern District of New York (a “foreign
action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction
of the state and federal courts located within the State of New York or the United States District Court for the Southern District of
New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”),
and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s
counsel in the foreign action as agent for such warrant holder.

 

		3.4	Counterparts. This Agreement may be executed in any number of original or facsimile counterparts
and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission
shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

 

		3.5	Effect of Headings. The section headings herein are for convenience only and are not part of this
Agreement and shall not affect the interpretation thereof.

 

		3.6	Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability
of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof.
Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a
part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and
enforceable.
