Exhibit 4.3

DESCRIPTION OF COMMON STOCK  

General

The following description summarizes the most important terms of our common stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth in this “Description of Common Stock,” you should refer to our articles of incorporation (the “articles of incorporation”), and second amended and restated bylaws, as amended (the “bylaws”), which are included as exhibits to our Annual Report on Form 10-K, and to the applicable provisions of Nevada law. Our authorized capital stock consists of 50,000,000 shares of common stock, par value $0.001 per share and 5,000,000 shares of preferred stock, par value $0.001 per share. Our board of directors is authorized, without stockholder approval, except as required by the listing standards of The Nasdaq Stock Market LLC, to issue additional shares of our capital stock.  

Common Stock

Voting Rights. Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Our bylaws provide that in contested director elections (meaning elections in which the number of nominees exceeds the number of directors to be elected), directors are elected by a plurality of the votes cast, and the nominees receiving the greatest numbers of votes are elected to serve as directors. Our bylaws further provide that our directors are elected in uncontested elections by a majority of the votes cast, meaning that a director nominee will be elected if the number of votes cast for that nominee’s election exceeds the number of votes cast against that nominee’s election.

Dividends. Subject to the preference in dividend rights of any series of preferred stock that we may issue in the future, the holders of common stock are entitled to receive such cash dividends, if any, as may be declared by our board of directors out of legally available funds.

Liquidation. In the event of any liquidation, dissolution or winding up, after payment of all debts and liabilities and after payment of the liquidation preferences of any shares of preferred stock then outstanding, the holders of the common stock will be entitled to participate pro rata in all assets that are legally available for distribution.

Rights and Preferences. Holders of common stock have no preemptive, subscription, redemption, sinking fund or conversion rights and are not subject to further calls or assessments. The rights and preferences of holders of common stock will be subject to the rights of any series of preferred stock that we may issue in the future.

Preferred Stock

Our board of directors, without any vote or action by our stockholders, has the authority to designate and issue up to an aggregate of 5,000,000 shares of preferred stock from time to time, in one or more classes or series or shares, on terms that it may determine, including among other things:

1

Our board of directors could issue all or part of the preferred stock with, among other things, substantial voting power or advantageous conversion rights. This stock could be issued to persons deemed by our board of directors likely to support our current management in a context for control of us, either as a precautionary measure or in response to a specific takeover threat.  The issuance of preferred stock could adversely affect the voting power of holders of common stock or reduce the likelihood that common stockholders would receive distributions or other payments upon liquidation. Any such issuance could have the effect of decreasing the market price of the common stock. The issuance of preferred stock also could have the effect of delaying, deterring or preventing a change in control.

Anti-Takeover Effects of Certain Provisions of Nevada Law and Our Articles of Incorporation and Bylaws

Anti-Takeover Effects of Certain Provisions of Nevada Law and Nevada Anti-takeover Statutes.

Certain provisions of the Nevada Revised Statutes, or NRS, as described below, 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.

Combinations with Interested Stockholders Statutes

Nevada’s “combinations with interested stockholders” statutes, NRS 78.411 through 78.444, inclusive, prohibit specified types of 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 (1) the corporation’s board of directors approves, in advance, either the combination itself, or the transaction by which such person becomes an interested stockholder, or (2) the combination is approved by the board of directors and 60% of the then-outstanding voting power of the corporation’s stockholders not beneficially owned by the interested stockholder, its affiliates and associates. Further, in the absence of the prior approval described above, certain restrictions may apply even after such two-year period. However, these statutes do not apply to any combination of a corporation and an interested stockholder after the expiration of four years after the person first became an interested stockholder.

For purposes of these statutes, an “interested stockholder” is any person who is (1) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (2) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of 10% 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 a corporation and an interested stockholder. These statutes generally apply to “resident domestic corporations,” namely Nevada corporations with 200 or more stockholders of record. However, a Nevada corporation may elect in its articles of incorporation not to be governed by these particular laws, but if such election is not made in the corporation’s original articles of incorporation, the amendment (1) must be approved by the affirmative vote of the holders of stock representing a majority of the outstanding voting power of the corporation not beneficially owned by interested stockholders or their affiliates and associates, and (2) is not effective until 18 months after the

2

vote approving the amendment and does not apply to any combination with a person who first became an interested stockholder on or before the effective date of the amendment.

Our original articles of incorporation include a provision providing that at such time, if any, that we become a “resident domestic corporation” as defined in the NRS, we will not be subject to, or governed by, any of the provisions of NRS 78.411 to 78.444, inclusive, as amended from time to time, or any successor statute.  As a result, pursuant to NRS 78.434, the “combinations with interested stockholders” statutes will not apply to us, unless our articles of incorporation are subsequently amended to provide that we are subject to those provisions.

Acquisition of Controlling Interest Statutes

Nevada’s “acquisition of controlling interest” statutes, NRS 78.378 through 78.3793, inclusive, contain provisions governing the acquisition of stockholder voting power above specified thresholds in certain Nevada corporations. These “control share” laws provide generally that any person that acquires a “controlling interest” in certain Nevada corporations may be denied voting rights, unless a majority of the disinterested stockholders of the corporation elects to restore such voting rights. These laws 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. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become “control shares” to which the voting restrictions described above apply.

In our bylaws, we have elected not to be governed by, and to otherwise opt out of, the provisions of NRS 78.378 to 78.3793, inclusive. Absent such provision in our bylaws, these statutes would apply to us as of a particular date if we were to have 200 or more stockholders of record (at least 100 of whom have addresses in Nevada appearing on our stock ledger at all times during the 90 days immediately preceding that date) and do business in the State of Nevada directly or through an affiliated corporation, unless our articles of incorporation or bylaws in effect on the tenth day after the acquisition of a controlling interest provide otherwise.

NRS 78.139(4) also provides that directors of a Nevada corporation may resist a change or potential change in control of the corporation if the board of directors determines that the change or potential change is opposed to, or not in, the best interest of the corporation upon consideration of any relevant facts, circumstances, contingencies or constituencies that the directors are entitled, but not required, to consider when exercising their directorial powers pursuant to NRS 78.138(4).

The existence of the foregoing provisions and other potential anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that you could receive a premium for your common stock in an acquisition.

Articles of Incorporation and Bylaw Provisions.

Our articles of incorporation and bylaws contain provisions that might have an anti-takeover effect. These provisions, which are summarized below, may have the effect of delaying, deterring or preventing a change in control of our company. They could also impede a transaction in which our stockholders might receive a premium over the then-current market price of our common stock and our stockholders’ ability to approve transactions that they consider to be in their best interests.

Articles of Incorporation. Our authorized but unissued shares of common stock and preferred stock are available for our board of directors to issue without stockholder approval. We may use these additional shares for a variety of corporate purposes, including future public or private offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of our authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our company by means of a proxy contest, tender offer, merger or other transaction. Our authorized but unissued shares may be used to delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders.

Bylaws. Certain provisions of our bylaws may be considered to have anti-takeover effects, including advance notice requirements for director nominations and other stockholder proposals. Our bylaws establish advance notice procedures for stockholder proposals to be brought before an annual meeting of stockholders, and for proposed nominations of candidates for election to our board of directors at an annual or special meeting of stockholders. Generally, such notices must be received by our corporate secretary at our principal executive offices, in the case of an annual meeting, between 90 days and 120 days prior to the first anniversary of the preceding year’s annual meeting and, in the case of a special meeting called for the purpose of electing directors, between 90 and 120 days prior to the date of the special meeting or within 10 days after the day on which public announcement of the date of the special meeting is first made by us. In addition, our board of directors has the authority to amend or repeal our bylaws, or to adopt new bylaws, which could have the effect of delaying, deterring or preventing a change of control.

Certain other provisions of Nevada Law and our Articles of Incorporation, and Bylaws

Certain provisions of Nevada Law, our articles of incorporation and bylaws, which are summarized below, could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they might also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

Removal of Directors. Directors may be removed with or without cause by the holders of not less than two-thirds of the voting power of all of our then-outstanding stock entitled to vote generally in the election of directors (voting as a single class), excluding stock entitled to vote only upon the happening of a fact or event unless such fact or event shall have occurred.

Resolutions to Change Authorized Number of Directors. The authorized number of directors shall be fixed from time to time by resolution of the Board of Directors but shall not be less than three or more than 10.

Vacancies may be Filled by Directors. All vacancies, including newly created directorships, shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors and the director(s) so chosen shall hold office until their successors are elected and qualified, at which the term of the class to which he or she has been elected expires, or until his or her earlier resignation or removal.

Advance Notice Procedures. Stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance and timely notice in writing, and also specify requirements as to the form and content of a stockholder’s

4

notice.

No Cumulative Voting Rights. Our articles of incorporation and bylaws do not provide for cumulative voting rights. As a result, the holders of a majority of the shares of common stock entitled to vote in any election of directors would have the ability to elect all of the directors standing for election.

Action by Written Consent; Special Meetings of Stockholders. Stockholder action can only be taken at an annual or special meeting of stockholders called and noticed in the manner required by the bylaws. The stockholders may not in any circumstance take action by written consent.

Authorized but Unissued Shares. Our authorized but unissued shares of common stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.
