addition to the powers and privileges conferred upon the Corporation by law, and those incidental thereto, the Corporation shall possess
and may exercise all the powers and privileges that are necessary or convenient to the conduct, promotion or attainment of the business
or purposes of the Corporation, including, but not limited to, effecting a merger, capital stock exchange, asset acquisition, stock purchase,

Stock”), and (ii) [___________________] ([________________])preferred stock, par value $[0.0001] per share (“Preferred
Stock”).

Common Stock.

General. All shares of Common Stock shall be identical and shall entitle the holders thereof to the same powers, preferences,
qualifications, limitations, privileges and other rights provided under the DGCL. The voting, dividend and liquidation rights of the
holders of the Common Stock are subject to and qualified by the rights of the holders of the Preferred Stock (when, if and to the
extent shares or series of such stock are designated and issued). The Board of Directors of the Corporation (the “Board
of Directors”), in its sole discretion, shall determine the terms and conditions (including the consideration to be
received by the Corporation) on which shares of Common Stock are to be issued.

Voting Rights. Each holder of record of Common Stock shall be entitled to one vote for each share of Common Stock standing in
such holder’s name on the books of the Corporation. Except as otherwise required by law or by or pursuant to Section (b) of
this Article FOURTH, the holders of Common Stock and the holders of Preferred Stock shall vote together as a single class on all
matters submitted to stockholders for a vote (including any action by written consent).

(iii) Dividends.
Subject to provisions of law and Section (b) of this Article FOURTH, the holders of Common Stock shall be entitled to receive
dividends out of funds legally available therefor at such times and in such amounts as the Board of Directors may determine in its
sole discretion.

(iv) Liquidation. Subject to provisions of law and Section (b) of this Article FOURTH, upon any liquidation, dissolution or winding
up of the Corporation, whether voluntary or involuntary, after the payment or provision for payment of all debts and liabilities of
the Corporation and any and all preferential amounts to which the holders of the Preferred Stock are entitled with respect to the
distribution of the net assets of the Corporation in liquidation, the holders of Common Stock shall be entitled to share ratably in
the remaining net assets of the Corporation available for distribution.

Preferred Stock.

(i) Issuance of Preferred Stock. The Board of Directors is expressly authorized, subject to limitations prescribed by the DGCL and
the provisions of this Certificate of Incorporation, to provide by resolution or resolutions from time to time, and by filing a
certificate(s) pursuant to the DGCL, for the issuance of shares of Preferred Stock in one or more class or series, to establish the
number of shares to be included in each such class or series, the consideration to be paid for such shares, and to fix the voting
powers (if any), designations, powers, preferences, and relative, participating, optional or other rights, if any, of the shares of
each such class or series, and any qualifications, limitations or restrictions of such preferences and rights, including, without
limitation, dividend rights, conversion rights, voting rights (if any), redemption privileges and liquidation preferences, as shall
be stated and expressed in such resolutions, in each instance as the Board of Directors may determine in its sole discretion and
without stockholder approval. Each class or series shall be designated so as to distinguish the shares thereof from the shares of
all other classes and series. All shares of a series of Preferred Stock shall have preferences, limitations and relative rights
identical with those of other shares of the same series and, except to the extent otherwise specifically provided in the designation
and description of the series, with those of other series of the same class.

Authority to Establish Variations Between Classes or Series of Preferred Stock. The authority of the Board of Directors with
respect to each class, or each series within a class shall include, but not be limited to, determination of the
following:

the distinctive designation of such class or series and the number of shares to constitute such class or series;

the rate at which dividends on the shares of such class or series shall be declared and paid, or set aside for payment, whether
dividends at the rate so determined shall be cumulative or accruing, and whether the shares of such class or series shall be
entitled to any participating or other dividends in addition to dividends at the rate so determined, and if so, on what terms or in
what events;

the right or obligation, if any, of the Corporation to redeem shares of the particular class or series of Preferred Stock and, if
redeemable, the price, terms and manner of such redemption;

the special and relative rights and preferences, if any, and the amount or amounts per share, which the shares of such class or
series of Preferred Stock shall be entitled to receive, in preference over any or all other class(es) or series, upon any voluntary
or involuntary liquidation, dissolution or winding up of the Corporation (and distribution of the net assets of the Corporation in
connection therewith);

the terms and conditions, if any, upon which shares of such class or series shall be convertible into, or exchangeable for, shares
of capital stock of any other class or series, including the price or prices or the rate or rates of conversion or exchange, the
terms and conditions of conversion or exchange, and the terms of adjustment, if any;

the obligation, if any, of the Corporation to retire, redeem or purchase shares of such class or series pursuant to a sinking fund
or fund of a similar nature or otherwise, and the terms and conditions of such obligation;

voting rights, if any, including special, conditional or limited voting rights with respect to any matter, including with respect to
the election of directors and matters adversely affecting any class or series of Preferred Stock;
