EXHIBIT 4.14





DESCRIPTION OF SECURITIES



The foregoing description is intended as a summary and is qualified
in its entirety by reference to our certificate of incorporation, as amended (the “Certificate of Incorporation”) and
our amended and restated by-laws, as amended (the “By-laws”) as currently in effect, copies of which are filed as exhibits
to this Amendment No. 1 to the Annual Report on Form 10-K and are incorporated by reference herein.



Authorized Capital Stock



As of December 31, 2019, we have
authorized 650,000,000 shares of capital stock, par value $0.001 per share, of which 600,000,000 are shares of common stock
and 50,000,000 are shares of “blank check” preferred stock. As of December 31, 2019, there were 164,701,167
shares of common stock issued and outstanding. The authorized and unissued shares of common stock and the authorized and
undesignated shares of preferred stock are available for issuance without further action by our stockholders, unless such
action is required by applicable law or the rules of any stock exchange on which our securities may be listed.



Common Stock



The holders of our common stock are entitled to one vote per
share. Our Certificate of Incorporation does not provide for cumulative voting. Our directors are divided into three classes. At
each annual meeting of stockholders, directors elected to succeed those directors whose terms expire are elected for a term of
office to expire at the third succeeding annual meeting of stockholders after their election. The holders of our common stock are
entitled to receive ratably such dividends, if any, as may be declared by our board of directors out of legally available funds.
Upon liquidation, dissolution or winding-up, the holders of our common stock are entitled to share ratably in all assets that are
legally available for distribution. There are no preemptive, subscription, conversion rights, redemption or sinking fund provisions
regarding the common stock. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely
affected by, the rights of the holders of any series of preferred stock, which may be designated solely by action of our board
of directors and issued in the future.



The transfer agent and registrar for our common stock is Action
Stock Transfer Corporation. The transfer agent’s address is 2469 East Fort Union Blvd., Suite 214, Salt Lake City, UT 84121.
Our common stock is listed on the NYSE American under the symbol “ATM.”



Preferred Stock



The board of directors is authorized, subject to any limitations
prescribed by law, without further vote or action by the stockholders, to issue from time to time up to 50,000,000 shares of preferred
stock in one or more series. Each such series of preferred stock shall have such number of shares, designations, preferences,
voting powers, qualifications, and special or relative rights or privileges as shall be determined by the board of directors,
which may include, among others, dividend rights, voting rights, liquidation preferences, conversion rights and preemptive rights.
Issuance of preferred stock by our board of directors may result in such shares having dividend and/or liquidation preferences
senior to the rights of the holders of our common stock and could dilute the voting rights of the holders of our common stock.













Prior to the issuance of shares of each
series of preferred stock, the board of directors is required by the Delaware General Corporation Law and our Certificate of Incorporation
to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The certificate
of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and restrictions,
including, but not limited to, some or all of the following:



| | ● | the
                                         number of shares constituting that series and the distinctive designation of that series,

                                         from time to time by action of the board of directors;

| | ● | whether
                                         or not the shares of that series will be redeemable, and, if so, the terms and conditions

| | ● | whether
                                         or not the shares of the series will have priority over or be on a parity with or be
                                         junior to the shares of any other series or class in any respect;

Anti-Takeover Law and Provisions of
our Certificate of Incorporation and By-laws





Provisions of our Certificate of Incorporation
and By-laws may delay or discourage transactions involving an actual or potential change in our control or change in our management,
including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders
might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common
stock. Among other things, our Certificate of Incorporation and By-laws:



| | ● | permits
                                         our board of directors to issue up to 50,000,000 shares of preferred stock, without further
                                         action by the stockholders, with any rights, preferences and privileges as they may designate,
                                         including the right to approve an acquisition or other change in control;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | ● | provide
                                         that all vacancies, including newly created directorships, may, except as otherwise required
                                         by law, be filled by the affirmative vote of a majority of directors in office;                                                                                                                                 
| | ● | divide
                                         our board of directors into three classes, with each class serving staggered three-year
                                         terms;                                                                                                                                                                                                                
| | ● | do
                                         not provide for cumulative voting rights (therefore allowing the holders of a majority
                                         of the shares of common stock entitled to vote in any election of directors to elect
                                         all of the directors standing for election, if they should so choose);                       
| | ● | provide
                                         that special meetings of our stockholders may be called only by our board of directors,
                                         chairman or chief executive officer; and                                                                                                                                                                             
| | ● | provide
                                         advance notice provisions with which a stockholder who wishes to nominate a director
                                         or propose other business to be considered at a stockholder meeting must comply.
