RESOLVED:
That the Third Amended and Restated Certificate of Incorporation of this corporation be amended as follows:

The

The total number of shares of all classes of stock which the Corporation shall have authority to issue is (i) twenty-five million (25,000,000)
shares of Common Stock, $0.0001 par value per share (“Common Stock”) and (ii) twelve million five hundred
thousand (12,500,000) shares of Preferred Stock, $0.0001 par value per share (“Preferred Stock”), of
which four million eight hundred fifty thousand (4,850,000) shares are designated Series A Preferred Stock and seven million six hundred
fifty thousand (7,650,000) shares are designated Blank Check Preferred Stock.”

The
first paragraph of ARTICLE FOURTH Part B. of the Third Amended and Restated Certificate of Incorporation shall be deleted and
replaced with the following:

PREFERRED STOCK

Seven
million six hundred fifty thousand (7,650,000) shares of the authorized Preferred Stock of the Corporation are hereby designated “Blank
Check Preferred Stock” that may be issued from time to time and in one or more series. The Board of Directors of the Corporation
is authorized to determine or alter the powers, preferences and rights, and the qualifications, limitations and restrictions granted
to or imposed upon any wholly unissued series of Blank Check Preferred Stock, and within the limitations or restrictions stated in any
resolution or resolutions of the Board of Directors originally fixing the number of shares constituting any series of Blank Check Preferred

of shares of any such series of Blank Check Preferred Stock, and to fix the number of shares of any series of Blank Check Preferred Stock.
In the event that the number of shares of any series of Blank Check Preferred Stock shall be so decreased, the shares constituting such

Section
3.2 of Part B. of Article FOURTH of the Third Amended and Restated Certificate of Incorporation shall be deleted and replaced
with the following:

“3.2. Election
of Directors. The holders of record of the shares of Common Stock, exclusively and as a separate class, shall be entitled to
elect two (2) directors of the Corporation; provided, however, for administrative convenience, any director elected as
provided in the preceding sentence may be removed without cause by, and only by, the affirmative vote of the holders of the shares
of the Common Stock given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written
consent of stockholders. If the holders of shares of Common Stock fail to elect a sufficient number of directors to fill all
directorships for which they are entitled to elect directors, voting exclusively and as a separate class, pursuant to the first
sentence of this Section 3.2, then any directorship not so filled shall remain vacant until such time as the holders of the
Common Stock elect a person to fill such directorship by vote or written consent in lieu of a meeting. The holders of record of the
shares of Common Stock and the holders of record of the shares of Series A Preferred Stock, exclusively and voting together as a
single class, shall be entitled to elect the balance of the total number of directors of the Corporation. At any meeting held for
the purpose of electing a director, the presence in person or by proxy of the holders of a majority of the outstanding shares of the
class or series entitled to elect such director shall constitute a quorum for the purpose of electing such director. Except as
otherwise provided in this Section 3.2, a vacancy in any directorship filled by the holders of any class or classes or series
shall be filled only by vote or written consent in lieu of a meeting of the holders of such class or classes or series or by any
remaining director or directors elected by the holders of such class or classes or series pursuant to this Section 3.2. The
rights of the holders of the Series A Preferred Stock under this Section 3.2 shall terminate on the first date following the
date the first share of Series A Preferred Stock was issued (the “Original Issue Date”) on which there are issued and
outstanding less than 782,500 shares of Preferred Stock (subject to appropriate adjustment in the event of any stock dividend, stock
split, combination, or other similar recapitalization with respect to the Series A Preferred Stock).”

Section
5.1 of Part B. of Article FOURTH of the Third Amended and Restated Certificate of Incorporation shall be deleted and replaced
with the following:

“5.1 Triggering
Event. Upon the closing of the sale of shares of Common Stock to the public in a public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, resulting in at least $7,500,000 of gross proceeds, net of the
underwriting discount and commissions, to the Corporation and in connection with such offering the Common Stock is listed for
trading on the Nasdaq Stock Market’s National Market, the New York Stock Exchange or another exchange or marketplace approved
the Board of Directors (the time of such closing or the date and time specified or the time of the event specified in such approval
is referred to herein as the “Mandatory Conversion Time”), then at the Mandatory Conversion Time (i) each outstanding
share of Series A Preferred Stock shall automatically be converted into shares of Common Stock at a conversion rate equal to the
greater of (A) the then effective conversion rate as calculated pursuant to Section 4.1.1 or (B) the Liquidation Amount of
the Series A Preferred Stock divided by the price per share of the Common Stock issued in the public offering and (ii) such shares
may not be reissued by the Corporation.”

WITNESS WHEREOF, this Second Amendment to the Third Amended and Restated Certificate of Incorporation has been executed by the President
