Document Content:

Representative shall notify the Company within ten (10) Business Days of its receipt of such written offer as to whether or not it agrees to accept such retention. If the Representative declines such retention (or does not respond within the ten (10) Business Day notice period), then the Company shall have no further obligations to the Representative pursuant to this Section 4.20 with respect to such Subject Transaction. For the avoidance of doubt, during the eighteen (18) month period covered by this Section 4.20, the Company shall provide written notice to the Representative prior to each Subject Transaction. 4.21 Subsequent Equity Sales. (a) Except for Exempt Issuances, from the date hereof until six (6) months after the Closing Date, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents.

(b) From
the date hereof until six (6) months after the Closing Date, the Company shall be prohibited from effecting or entering into an agreement
to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units
thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company
(i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to
receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based
upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of
such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date
after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly
related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction under, any agreement,
including, but not limited to, an equity line of credit, whereby the Company may issue securities at a future determined price. Any Underwriter
shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to
any right to collect damages.

(c) Notwithstanding
the foregoing, this Section 4.21 shall not apply in respect of an Exempt Issuance, except that, other than the terms of the Securities
Purchase Agreement dated December 30, 2025 by and between the Company and the signatories thereto, no Variable Rate Transaction shall
be an Exempt Issuance.

4.22 Capital
Changes. Until one hundred twenty (120) days after the Closing Date, the Company shall not undertake a reverse or forward stock split
or reclassification of the Common Stock without the prior written consent of the Representative.

4.23 Research
Independence. The Company acknowledges that each Underwriter’s research analysts and research departments, if any, are required
to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and
that such Underwriter’s research analysts may hold and make statements or investment recommendations and/or publish research reports
with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company hereby waives and releases,
to the fullest extent permitted by law, any claims that the Company may have against such Underwriter with respect to any conflict of
interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be
different from or inconsistent with the views or advice communicated to the Company by such Underwriter’s investment banking divisions.
The Company acknowledges that each Representative is a full-service securities firm and as such from time to time, subject to applicable
securities laws, may effect transactions for its own account or the account of its customers and hold long or short position in debt or
equity securities of the Company.

4.24 Tail
Period. Notwithstanding any other provision of this Agreement, including, but not limited to, Section 4.20 of this Agreement, for
a period during the period commencing on the Initial Closing and continuing for a period of eighteen (18) months from the date of this
Agreement, if the Company completes any financing of equity, equity-linked, convertible or debt or other capital raising activity with,
or receives any proceeds from, any of the investors introduced by the Representative via email communication to which the investor responds,
teleconference, videoconference, in-person or other meeting with the Company, the Company agrees to pay to the Representative, upon the
closing of such financing or receipt of such proceeds, compensation equivalent to an underwriting discount of seven percent (7%) to the
public offering price and Representative’s Warrants to purchase an aggregate of eight percent (8%) of the number of securities sold
in such financing.

DEFAULT BY UNDERWRITERS

If on the Closing Date or
any Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Closing Securities or Option Securities,
as the case may be, which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on
the part of the Company), the Representative, or if a Representative is the defaulting Underwriter, the non-defaulting Underwriters, shall
use their reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from
the Company such amounts as may be agreed upon and upon the terms set forth herein, the Closing Securities or Option Securities, as the
case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours the Representative shall not
have procured such other Underwriters, or any others, to purchase the Closing Securities or Option Securities, as the case may be, agreed
to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of Closing Securities or Option Securities,
as the case may be, with respect to which such default shall occur does not exceed 10% of the Closing Securities or Option Securities,
as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Closing
Securities or Option Securities, as the case may be, which they are obligated to purchase hereunder, to purchase the Closing Securities
or Option Securities, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate
number of Closing Securities or Option Securities, as the case may be, with respect to which such default shall occur exceeds 10% of the
Closing Securities or Option Securities, as the case may be, covered hereby, the Company or the Representative will have the right to
terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided
in Article VI hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Article V, the applicable Closing
Date may be postponed for such period, not exceeding seven days, as the Representative, or if a Representative is the defaulting Underwriter,
the non-defaulting Underwriters, may determine in order that the required changes in the Prospectus or in any other documents or arrangements
may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under
this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.
