Exhibit 4.1

DESCRIPTION OF SECURITIES

Our amended and restated articles of incorporation authorize us to issue 200,000,000 shares of common stock, par value $0.001 per share and 10,000,000 shares of preferred stock, par value $0,001 per share. As of March 25, 2024, we had 26,392,315 shares of common stock and no shares of preferred stock outstanding.

Common Stock

The following description of our common stock, may not be complete and is subject to, and qualified in its entirety by reference to, Nevada law and the actual terms and provisions contained in our amended and restated articles of incorporation and our bylaws, each as amended from time to time.

Voting Rights: Each outstanding share of our common stock is entitled to one vote per share of record on all matters submitted to a vote of stockholders and to vote together as a single class for the election of directors and in respect of other corporate matters. At a meeting of stockholders at which a quorum is present, for all matters other than the election of directors, an affirmative vote of the majority of shares entitled to vote on a matter and that are represented either in person or by proxy at a meeting of stockholders decides all questions, unless the matter is one upon which a different vote is required by express provision of law or our amended and restated articles incorporation or our bylaws. Directors will be elected by a plurality of the votes of the shares present at a meeting. Holders of shares of common stock do not have cumulative voting rights with respect to the election of directors or any other matter.

Dividends: Holders of our common stock are entitled to receive dividends or other distributions when, as and if declared by our board of directors. The right of our board of directors to declare dividends, however, is subject to any rights of the holders of other classes of our capital stock, any indebtedness outstanding from time to time and the availability of sufficient funds, as determined under Nevada law, to pay dividends.

Preemptive Rights: The holders of our common stock do not have preemptive rights to purchase or subscribe for any of our capital stock or other securities

Redemption: Shares of our common stock are not subject to redemption by operation of a sinking fund or otherwise.

Liquidation Rights: In the event of any liquidation, dissolution, or winding up of our company, subject to the rights, if any, of the holders of other classes of our capital stock, the holders of shares of our common stock are entitled to receive any of our assets available for distribution to our stockholders ratably in proportion to the number of shares held by them.

Listing: Our common stock is traded on the Nasdaq Capital Market under the symbol “USIO.” 

Transfer Agent and Registrar: The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC, 6201 15th Avenue, Brooklyn, NY 11219, telephone (718) 921-8200.

Preferred Stock

Under our amended and restated articles of incorporation, as amended, we have the authority to issue 10,000,000 shares of preferred stock, par value $0.01 per share, which are issuable in series on terms to be determined by our board of directors. Accordingly, our board of directors is authorized, without action by the stockholders, to issue preferred stock from time to time with such dividend, liquidation, conversion, voting, redemption, sinking fund and other rights and restrictions as it may determine. All shares of any one series of our preferred stock will be identical, except that shares of any one series issued at different times may differ as to the dates from which dividends may be cumulative. The Board may determine:

● the distinctive designation of each series and the number of shares that will constitute the series;

● the voting rights, if any, of shares of the series and the terms and conditions of the voting rights;

● the dividend rate on the shares of the series, the dates on which dividends are payable, any restriction, limitation or condition upon the payment of dividends, whether dividends will be cumulative, and the dates from and after which dividends shall accumulate;

● the prices at which, and the terms and conditions on which, the shares of the series may be redeemed, if the shares are redeemable;

● the terms and conditions of a sinking or purchase fund for the purchase or redemption of shares of the series, if such a fund is provided;

● any preferential amount payable upon shares of the series in the event of the liquidation, dissolution or winding up of, or upon the distribution of any of our assets; and

● the prices or rates of conversion or exchange at which, and the terms and conditions on which, the shares of the series may be converted or exchanged into other securities, if the shares are convertible or exchangeable.

If our board of directors decides to issue any shares of preferred stock, it may discourage or make more difficult a merger, tender offer, business combination or proxy contest, assumption of control by a holder of a large block of our securities, or the removal of incumbent management, even if these events were favorable to the interests of stockholders. Our board of directors, without stockholder approval, may issue preferred stock with voting and conversion rights and dividend and liquidation preferences that may adversely affect the holders of our other equity or debt securities.

Certain Provisions of Nevada Law And Our Charter And Bylaws

The following paragraphs summarize certain provisions of Nevada law and our restated articles of incorporation, as amended, and our amended and restated bylaws, as amended. The summary does not purport to be complete and is subject to and qualified in its entirety by reference to Nevada law and to our restated certificate of incorporation, as amended, and our amended and restated bylaws, as amended, copies of which are on file with the SEC as exhibits to reports previously filed by us.

General

Certain provisions of our amended and restated articles of incorporation, as amended, and our amended and restated bylaws and Nevada law could make our acquisition by a third party, a change in our incumbent management, or a similar change in control more difficult, including:

● An acquisition of us by means of a tender or exchange offer;

● An acquisition of us by means of a proxy contest or otherwise; or

● The removal of a majority or all of our incumbent officers and directors.

These provisions, which are summarized below, are likely to discourage certain types of coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that these provisions help to protect our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that this benefit outweighs the potential disadvantages of discouraging such a proposal because our ability to negotiate with the proponent could result in an improvement of the terms of the proposal. The existence of these provisions which are described below could limit the price that investors might otherwise pay in the future for our securities.

Articles of Incorporation and Bylaws

Authorized But Unissued Capital Stock. We have shares of common stock and preferred stock available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of any securities exchange on which our stock may be listed. We may utilize these additional shares for a variety of corporate purposes, including for future public offerings to raise additional capital or facilitate corporate acquisitions or for payment as a dividend on our capital stock. The existence of unissued and unreserved common stock and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a controlling interest in our company by means of a merger, tender offer, proxy contest, or otherwise. In addition, if we issue preferred stock, the issuance could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation.

Blank Check Preferred Stock. Our board of directors, without stockholder approval, has the authority under our amended and restated articles of incorporation, as amended, to issue preferred stock with rights superior to the rights of the holders of common stock. As a result, preferred stock could be issued quickly and easily, could impair the rights of holders of common stock, and could be issued with terms calculated to delay or prevent a change in control or make removal of management more difficult.

Election of Directors. Our amended and restated bylaws provide that a majority of directors then in office may fill any vacancy occurring on our board of directors, even though less than a quorum may then be in office. These provisions may discourage a third party from voting to remove incumbent directors and simultaneously gaining control of our board of directors by filling the vacancies created by that removal with its own nominees.

Removal of Directors. A director may be removed from office only by the affirmative vote of two-thirds or more of the combined voting power of the then issued and outstanding shares of our capital stock entitled to vote in the election of directors, voting together as a single class. 

Anti-takeover Effects of Nevada Law

Business Combinations with Interested Stockholders

The “business combination with interested stockholders” provisions of Sections 78.411 to 78.444, inclusive, of the Nevada Revised Statutes, or NRS, generally prohibit a Nevada corporation with at least 200 stockholders of record from engaging in various “combination” transactions with any interested stockholder for a period of two years after the date of the transaction in which the person became an interested stockholder, unless the combination is approved by our board of directors prior to the date the interested stockholder obtained such status or the combination is approved by our board of directors and at such time or thereafter is approved at a meeting of the stockholders by the affirmative vote of stockholders representing at least 60% of the outstanding voting power held by disinterested stockholders, and extends beyond the expiration of the two-year period, unless:

● the combination was approved by our board of directors prior to the person becoming an interested stockholder or the transaction by which the person first became an interested stockholder was approved by our board of directors before the person became an interested stockholder or the combination is later approved by a majority of the voting power held by disinterested stockholders; or

● if the consideration to be paid by the interested stockholder is at least equal to the highest of: (a) the highest price per share paid by the interested stockholder within the two years immediately preceding the date of the announcement of the combination or in the transaction in which it became an interested stockholder, whichever is higher; (b) the market value per share of common stock on the date of announcement of the combination and the date the interested stockholder acquired the shares, whichever is higher; or (c) for holders of preferred stock, the highest liquidation value of the preferred stock, if it is higher.

Notwithstanding the foregoing, NRS 78.411 to 78.444, inclusive, do not apply to any combination of a resident domestic corporation with an interested stockholder after the expiration of four years after the person first became an interested stockholder.

A “combination” is generally defined to include mergers or consolidations or any sale, lease exchange, mortgage, pledge, transfer, or other disposition, in one transaction or a series of transactions, with an “interested stockholder” having: (a) an aggregate market value equal to more than 5% of the aggregate market value of the assets of the corporation, (b) an aggregate market value equal to more than 5% of the aggregate market value of all outstanding voting shares of the corporation, (c) more than 10% of the earning power or net income of the corporation, and (d) certain other transactions with an interested stockholder or an affiliate or associate of an interested stockholder.

In general, an “interested stockholder” is a person who, together with affiliates and associates, owns (or within two years, did own) 10% or more of a corporation’s voting stock. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire our company even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

A Nevada corporation may “opt out” of these provisions either with an express provision in its original articles of incorporation or in an amendment to its articles of incorporation or bylaws approved by its stockholders. However, we have not opted out, and do not currently intend to opt out of, these provisions. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us.

Control Share Acquisitions

The “control share” provisions of Sections 78.378 to 78.3793, inclusive, of the NRS apply to “issuing corporations” that are Nevada corporations with at least 200 stockholders of record, including at least 100 stockholders of record who are Nevada residents, and that conduct business directly or indirectly in Nevada. The control share statute prohibits an acquirer, under certain circumstances, from voting its shares of a target corporation’s stock after crossing certain ownership threshold percentages, unless the acquirer obtains approval of the target corporation’s disinterested stockholders. The statute specifies three thresholds: one-fifth or more but less than one-third, one-third but less than a majority, and a majority or more, of the outstanding voting power. Generally, once an acquirer crosses one of the above thresholds, those shares in an offer or acquisition and acquired within 90 days thereof become “control shares” and such control shares are deprived of the right to vote until disinterested stockholders restore the right. These provisions also provide that if control shares are accorded full voting rights and the acquiring person has acquired a majority or more of all voting power, all other stockholders who do not vote in favor of authorizing voting rights to the control shares are entitled to demand payment for the fair value of their shares in accordance with statutory procedures established for dissenters’ rights.  

A corporation may elect to not be governed by, or “opt out” of, the control share provisions by making an election in its articles of incorporation or bylaws, provided that the opt-out election must be in place on the 10th day following the date an acquiring person has acquired a controlling interest, that is, crossing any of the three thresholds described above. We have not opted out of the control share statutes, and will be subject to these statutes if we are an “issuing corporation” as defined in such statutes.

The effect of the Nevada control share statutes is that the acquiring person, and those acting in association with the acquiring person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders at an annual or special meeting. The Nevada control share law, if applicable, could have the effect of discouraging takeovers of our company.
