Description of Registrants Securities

Exhibit 4.5

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT
TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

The following is a description of our common stock and provisions of our Articles of Incorporation and amended and restated bylaws, each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K to which this Exhibit 4.5 is a part. This summary does not purport to be complete and is qualified in its entirety by the full text of our aforementioned Articles of Incorporation and amended and restated bylaws and by applicable law.

Our Certificate of Incorporation authorizes us to issue up to 150,000,000 shares of Class A Common Stock and 10,000,000 shares of preferred stock, par value $0.001 per share, all of which shares of preferred stock are currently undesignated. Our board of directors may establish the rights and preferences of the preferred stock from time to time.

Voting

Holders of our Class A Common Stock are entitled to receive notice of and attend any general meeting of the Company. In addition, holders of our Class A Common Stock shall have the right to vote at any such meeting on the basis of one vote for each such share held.

Dividends

Holders of our Class A Common Stock shall, in the absolute discretion of the Board, be entitled to receive dividends as and when declared by the directors out of monies of the Company properly applicable to the payment of dividends. We have never declared or paid any cash dividends on our Class A Common Stock. We currently intend to retain future earnings, if any, to finance the expansion of our business. As a result, we do not anticipate paying any cash dividends in the foreseeable future.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of our Class A Common Stock will be entitled to share ratably in the net assets legally available for distribution to shareholders after the payment of all of our debts and other liabilities, and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of preferred stock.

Rights and Preferences

In the event of the liquidation, dissolution or winding-up of the Company or other distribution of assets of the Company for the purpose of winding-up its affairs or upon a reduction of capital the holders of our Class A Common Stock shall share equally, share for share, in the assets and property of the Company.

Anti-Takeover Effects of Our Articles of Incorporation and Wyoming General Corporation Law

Our Articles of Incorporation provide for unlimited authorized shares of our Class A Common Stock. Our authorized but unissued shares of Class A Common Stock will be available for future issuance without shareholder 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 unlimited authorized but unissued shares of Class A Common Stock could render more difficult or discourage an attempt to obtain control of a majority of our Class A Common Stock by means of a proxy contest, tender offer, merger or otherwise.

Though not now, we may be or in the future we may become subject to Wyoming’s control share law. The law focuses on the acquisition of a “controlling interest” which means the ownership of outstanding voting shares sufficient, but for the control share law, to enable the acquiring person to exercise the following proportions of the

voting power of the corporation in the election of directors: (i) one-fifth or more but less than one-third, (ii) one-third or more but less than a majority, or (iii) a majority or more. The ability to exercise such voting power may be direct or indirect, as well as individual or in association with others. The effect of the control share law is that the acquiring person, and those acting in association with it, obtains only such voting rights in the control shares as are conferred by a resolution of the shareholders of the corporation, approved at a special or annual meeting of shareholders. The control share law contemplates that voting rights will be considered only once by the other shareholders. Thus, there is no authority to strip voting rights from the control shares of an acquiring person once those rights have been approved. If the shareholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares. The acquiring person is free to sell its shares to others. If the buyers of those shares themselves do not acquire a controlling interest, their shares do not become governed by the control share law. If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, any shareholder of record, other than an acquiring person, who has not voted in favor of approval of voting rights is entitled to demand fair value for such shareholder’s shares.

Wyoming’s control share law may have the effect of discouraging takeovers of the corporation. In addition to the control share law, Wyoming has a business combination law which prohibits certain business combinations between Wyoming corporations and “interested stockholders” for three years after the “interested stockholder” first becomes an “interested stockholder,” unless the corporation’s board of directors approves the combination in advance. For purposes of Wyoming law, an “interested stockholder” is any person who is (i) the beneficial owner, directly or indirectly, of fifteen percent or more of the voting power of the outstanding voting shares of the corporation, or (ii) an affiliate or associate of the corporation and at any time within the three previous years was the beneficial owner, directly or indirectly, of fifteen percent or more of the voting power of the then outstanding shares of the corporation. The definition of the term “business combination” is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation’s assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other shareholders. The effect of Wyoming’s business combination law is to potentially discourage parties interested in taking control of the Company from doing so if it cannot obtain the approval of our Board.

Choice of Forum

Our Certificate of Incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for:

The provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act.

The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any action, a court could find the choice of forum provisions contained in our Certificate of Incorporation to be inapplicable or unenforceable in such action. Our Certificate of Incorporation further provides that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision.
