Description of the Registrants Securities Under Section 12 of the Securities Exchange Act of 1934

Exhibit 4.3

DESCRIPTION OF SECURITIES

The following description is a general summary of the terms of our common stock and preferred stock. This summary does not purport to be complete and is qualified in its entirety by reference to the provisions of our Articles of Incorporation and Bylaws, as amended, copies of which have been incorporated by reference as exhibits to this Form 10-K, and to the applicable provisions of Oregon law. We encourage you to read our Articles of Incorporation, Bylaws and the applicable provisions of Oregon law carefully.

General

Under our Articles of Incorporation, we are authorized to issue 75,000,000 shares, of which 50,000,000 have been designated shares of common stock, without par value, and 25,000,000 have been designated shares of preferred stock, without par value, of which 200,000 shares of preferred stock have been designated as Series A participating preferred stock.

Common Stock

Holders of common stock are entitled to one vote per share on all matters to be voted upon by the shareholders. There are no cumulative voting rights. Holders of common stock have no preemptive or conversion rights and are entitled to receive ratable dividends when and if declared by the board of directors out of funds legally available for the payment of dividends, subject to any preferential rights of any then-outstanding preferred stock. There are no redemption or sinking fund provisions applicable to common stock. Subject to the rights of holders of any preferred stock, holders of common stock are entitled to share ratably in our assets legally available for distribution to shareholders in the event of our liquidation, dissolution or winding up after payment of or adequate provision for all our known debts and liabilities. Our common stock is listed on the New York Stock Exchange under the symbol “GBX.”

Preferred Stock

The board of directors may, without further action by the shareholders, issue preferred stock in one or more series and fix the rights and preferences of the preferred stock, including voting rights, dividend rates, conversion rights, terms of redemption (including sinking fund provisions) and liquidation preferences. The issuance of preferred stock by action of the board of directors could adversely affect the voting power, dividend rights and other rights of holders of common stock. Issuance of a series of preferred stock also could, depending upon the terms of series, impede the completion of a merger, tender offer or other takeover attempt.

Antitakeover Provisions

Our Articles of Incorporation and Bylaws, as currently in effect, contain provisions that may have the effect of delaying, deferring or preventing a change in control of our ownership or management. They provide for:

Antitakeover Effects of Provisions of Oregon Law

Oregon Takeover Statute; Hostile Takeovers. The Oregon Control Share Act, or OCSA, regulates the process by which a person may acquire control of certain Oregon-based corporations without the consent and cooperation of the board of directors. The OCSA provisions restrict a shareholder’s ability to vote shares of stock acquired in certain transactions not approved by the board that cause the acquiring person to gain control of a voting position exceeding one-fifth, one-third, or one-half of the votes entitled to be cast in an election of directors. Shares acquired in a control share acquisition have no voting rights except as authorized by a vote of the shareholders. A corporation may opt out of the OCSA by provision in the corporation’s articles of incorporation or bylaws. We have not opted out of the coverage of the OCSA.

Interested Shareholder Transactions. Except under certain circumstances, the Oregon Business Corporation Act, or OBCA, prohibits a “business combination” between a corporation and an “interested shareholder” within three years of the shareholder becoming an “interested shareholder.” Generally, an “interested shareholder” is a person or group that directly or indirectly owns, controls, or has the right to acquire or control, the voting or disposition of 15% or more of the outstanding voting stock or is an affiliate or associate of the corporation and was the owner of 15% or more of such voting stock at any time within the previous three years. A “business combination” is defined broadly to include, among others, (i) mergers and sales or other dispositions of 10% or more of the assets of a corporation with or to an interested shareholder, (ii) certain transactions resulting in the issuance or transfer to the interested shareholder of any stock of the corporation or its subsidiaries, (iii) certain transactions which would result in increasing the proportionate share of the stock of a corporation or its subsidiaries owned by the interested shareholder, and (iv) receipt by the interested shareholder of the benefit (except proportionately as a shareholder) of any loans, advances, guarantees, pledges, or other financial benefits. A business combination between a corporation and an interested shareholder is prohibited for three years following the date that the shareholder became an “interested shareholder” unless (i) prior to the date the person became an interested shareholder, the board of directors approved either the business combination or the transaction which resulted in the person becoming an interested shareholder, (ii) upon consummation of the transaction that resulted in the person becoming an interested shareholder, that person owns at least 85% of the corporation’s voting stock outstanding at the time the transaction is commenced (excluding shares owned by persons who are both directors and officers and shares owned by employee stock plans in which participants do not have the right to determine confidentially whether shares will be tendered in a tender or exchange offer), or (iii) the business combination is approved by the board of directors and authorized by the affirmative vote (at an annual or special meeting and not by written consent) of at least two-thirds of the outstanding voting stock not owned by the interested shareholder.

These restrictions placed on interested shareholders by the OBCA do not apply under certain circumstances, including, but not limited to, the following: (i) if the corporation’s original articles of incorporation contain a provision expressly electing not to be governed by the applicable section of the OBCA; or (ii) if the corporation, by action of its shareholders, adopts an amendment to its bylaws or articles of incorporation expressly electing not to be governed by the applicable section of the OBCA, provided that such an amendment is approved by the affirmative vote of not less than a majority of the outstanding shares entitled to vote. Such an amendment, however, generally will not be effective until 12 months after its adoption and will not apply to any business combination with a person who became an interested shareholder at or prior to such adoption. We have not elected to be outside the coverage of the applicable sections of the OBCA.

Board Of Directors’ Criteria For Evaluating Business Combinations. Under the OBCA, members of the board of directors of a corporation are authorized to consider certain factors in determining the best interests of the corporation when evaluating any (i) offer of another party to make a tender or exchange offer, (ii) merger or consolidation proposal, or (iii) offer of another party to purchase or otherwise acquire all or substantially all of the assets of the corporation. These factors include the social, legal and economic effects on employees, customers and suppliers of the corporation and on the communities and geographical areas in which the corporation and its subsidiaries operate, the economy of the state and the nation, the long-term and short-term interests of the corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the corporation, and other relevant factors.

Number of Directors; Filling Vacancies

Our Bylaws, as currently in effect, provide that the number of directors shall be ten. The shareholders and the board of directors have the authority to adopt, repeal or amend the bylaws. The affirmative vote of a majority of the total number of votes of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class, may remove any director only with cause. Unless previously filled by the holders of at least a majority of the shares of capital stock entitled to vote for the election of directors, vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by a majority vote of the directors then in office, even if less than a quorum, or by a sole remaining director.
