Neither treasury shares, nor shares of its own stock held by the Corporation in a fiduciary capacity shall be voted at any meeting or counted in determining the total number of outstanding shares at any given time. Shares standing in the name of another corporation, domestic or foreign, may be voted by such officer, agent or proxy as the Bylaws of such corporation may prescribe or, in the absence of such provision, as the Board of Directors of such corporation may determine.

Shares held by an administrator, executor, guardian or conservator may be voted by him, either in person or by proxy, without a transfer of such shares into his name.

If a quorum is present, the affirmative vote of a majority of the shares represented at the meeting and entitled to vote on the subject matter shall be the act of the Shareholders unless the vote of a greater number or voting by classes is required by the statutes of the State of Colorado or the Articles of Incorporation. In the event any Shareholders withdraw from a duly organized meeting at which a quorum was initially present, the remaining shares represented shall constitute a quorum for the purpose of continuing to do business, and the affirmative vote of the majority of the remaining shares represented at the meeting and entitled to vote on the subject matter shall be the act of the Shareholders unless the vote of a greater number or voting by classes is required by the statutes of the State of Colorado or the Articles of Incorporation.
