Document

The following is a summary description of common stock of Ekso Bionics Holdings, Inc. (the “Company” or “we,” “us” or “our”), which are the only securities of the Company registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The following summary does not purport to be complete and is subject to and qualified in its entirety by reference to the applicable provisions of Nevada law, our articles of incorporation, as amended (“charter”) and our bylaws (“bylaws”). For a complete description of our common stock, we refer you to our charter and our bylaws, which are included as exhibits to our Annual Report on Form 10-K for the year ended December 31, 2021.

Liquidation Rights. Upon liquidation, dissolution or winding up of our Company, the assets legally available for distribution to stockholders are distributable ratably among the holders of the common stock after payment of liquidation preferences, if any, on any outstanding payment of other claims of creditors. Each outstanding share of common stock is duly and validly issued, fully paid and non-assessable.

Nevada Revised Statutes (“NRS”) sections 78.411 to 78.444 prohibit certain business “combinations” between certain Nevada corporations and any person deemed to be an “interested stockholder” for two years after such person first becomes an “interested stockholder” unless (i) the corporation’s Board of Directors approves the combination (or the transaction by which such person becomes an “interested stockholder”) in advance, or (ii) the combination is approved by the Board of Directors and sixty percent of the corporation’s voting power not beneficially owned by the interested stockholder, its affiliates and associates. Furthermore, in the absence of prior approval, certain restrictions may apply even after such two-year period. For purposes of these statutes, an “interested stockholder” is any person who is (x) the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the outstanding voting shares of the corporation, or (y) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the then outstanding shares of the corporation. The definition of the term “combination” is sufficiently broad to cover most significant transactions between the corporation and an “interested stockholder”. Subject to certain timing requirements set forth in the statutes, a corporation may elect not to be governed by these statutes. We have not included any such provision in our articles of incorporation. The effect of these statutes may be to potentially discourage parties interested in taking control of the Company from doing so if it cannot obtain the approval of our Board of Directors.

Nevada law also seeks to impede “unfriendly” corporate takeovers by providing in Sections 78.378 to 78.3793 of the NRS, commonly referred to as the “Control Share Act”, that an “acquiring person” shall only obtain voting rights in the “control shares” purchased by such person to the extent approved by the other stockholders. With certain exceptions, an acquiring person is one who acquires or offers to acquire a “controlling interest” in the corporation. These statutes provide that a person acquires a “controlling interest” whenever a person acquires shares of a subject corporation that, but for the

application of these provisions of the NRS, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority or (3) a majority or more, of all of the voting power of the corporation in the election of directors. Control shares include not only shares acquired or offered to be acquired in connection with the acquisition of a controlling interest, but also all shares acquired by the acquiring person within the preceding 90 days. The statute covers not only the acquiring person but also any persons acting in association with the acquiring person. The NRS control share statutes only apply to issuers that have 200 or more stockholders of record, at least 100 of whom have had addresses in Nevada appearing on the stock ledger of the corporation at all times during the 90 days immediately preceding such date; and whom do business in Nevada directly or through an affiliated corporation. At this time, we do not believe we have 100 shareholders of record who have addresses in Nevada and we do not conduct business in Nevada directly or through an affiliated corporation. Therefore, the provisions of the Control Share Act are believed not to apply to acquisitions of our shares and will not until such time as these requirements have been met. At such time as they may apply, the provisions of the Control Share Act may discourage companies or persons interested in acquiring a significant interest in or control of us, regardless of whether such acquisition may be in the interest of our shareholders.
