The meeting shall be held at least once in a 12-month period and shall be on a date to be determined by the Board of Directors. The business to be transacted at the meeting shall be the election of directors and such other business as properly brought before the meeting.

At this meeting the election of directors shall take place, and the election and any other business transacted shall have the same force and effect as at an annual meeting duly called and held.

(c) No change in the time or place for a meeting for the election of directors shall be made within 20 days preceding the day on which the election is to be held. Written notice of any change shall be given each stockholder at least 20 days before the election is held, either in person or by letter mailed to the stockholder at the address last shown on the books of the Corporation.

(d) In the event the annual meeting is not held at the time prescribed in Article II, Section 1(a) above, and if the Board of Directors shall not call a special meeting as prescribed in Article II, Section 1(b) above within three months after the date prescribed for the annual meeting, then any stockholder may call that meeting, and at that meeting the stockholders may elect the directors and transact other business with the same force and effect as at an annual meeting duly called and held.

Section 2. Special Meetings.

Special meetings of the stockholders may be called by the Board of Directors. At any time, upon the written request of any person or persons entitled to call a special meeting, it shall be the duty of the Secretary to send out notices of the meeting, to be held within or without the State of Colorado and at such time, but not less than 10 days nor more than 60 days after receipt of the request, as may be fixed by the Board of Directors. If the Board of Directors fails to fix a time or place, the meeting shall be held at the principal office of the Corporation at a time as shall be fixed by the Secretary within the above limits.

Section 3. Notice and Purpose of Meetings; Waiver.

Each stockholder of record entitled to vote at any meeting shall be given in person, or by mail, or by prepaid telegram, written or printed notice of the purpose or purposes, and the time and place within or outside the State of Colorado of every meeting of stockholders. This notice shall be delivered not less than ten (10) days nor more than sixty (60) days before the meeting. If mailed or telegraphed, it should be directed to the stockholder at the address last shown on the books of the Corporation. No publication of the notice of meeting shall be required. A stockholder may waive the notice of meeting by attendance, either in person or by proxy, at the meeting, or by so stating in writing, either before or after the meeting. Attendance at a meeting for the express purpose of objecting that the meeting was not lawfully called or convened shall not, however, constitute a waiver of notice. Except where otherwise required by law, notice need not be given of any adjourned meeting of the stockholders.

Section 4. Quorum.

Except as otherwise provided by law, a quorum at all meetings of stockholders shall consist of the holders of record of a majority of the shares entitled to vote present in person or by proxy.

(a) In order to determine the holders of record of the Corporation’s stock who are entitled to notice of meetings, to vote at a meeting or its adjournment, to receive payment of any dividend, or to make a determination of the stockholders of record for any other proper purpose, the Board of Directors of the Corporation may order that the Stock Transfer Books be closed for a period not to exceed seventy days. If the purpose of this closing is to determine who is entitled to notice of a meeting and to vote at such meeting, the Stock Transfer Books shall be closed for at least thirty days preceding such meeting.

(b) In lieu of closing the Stock Transfer Books, the Board of Directors may fix a date as the record date for the determination of stockholders. This date shall be no more than seventy days prior to the date of the action which requires the determination, nor, in the case of a stockholders’ meeting, shall it be less than thirty days in advance of such meeting.

(c) If the Stock Transfer Books are not closed and no record date is fixed for the determination of the stockholders of record, the date of which notice of the meeting is mailed, or on which the resolution of the Board of Directors declaring a dividend is adopted, as the case may be, shall be the record date for the determination of stockholders.

(d) When a determination of stockholders entitled to vote at any meeting has been made as provided in this section, this determination shall apply to any adjournment of the meeting, except when the determination has been made by the closing of the Stock Transfer Books and the stated period of closing has expired.

In case there are vacancies on the Board of Directors, other than vacancies created by the removal of a director or directors by the stockholders or by an increase in the number of directors, the remaining directors, although less than a quorum, may by a majority vote elect a successor or successors for the unexpired term or terms.

Section 2. Meetings.

Meetings of the Board of Directors may be held either within or without the State of Colorado.

Section 3. Removal.

(a) At any meeting of the stockholders, any director or directors may be removed from office, without assignment of any reason, by a majority vote of the shares or class of shares, as the case may be, which elected the director or directors to be removed, provided, however, that if less than all the directors are to be removed, no individual director shall be removed if the number of votes cast against her or his removal would be sufficient, if cumulatively voted at an election of the entire board, to elect one or more directors.

(b) When any director or directors are removed, new directors may be elected at the same meeting of the stockholders for the unexpired term of the director or directors removed. If the stockholders fail to elect persons to fill the unexpired term or terms of the director or directors removed, these unexpired terms shall be considered vacancies on the board to be filled by the remaining directors.

The individual shall have no right to reimbursement, however, in relation to matters as to which he or she has been adjudged liable to the Corporation for negligence or misconduct in the performance of his or her duties, or was derelict in the performance of his or her duty as director, officer or employee by reason of willful misconduct, bad faith, gross negligence or reckless disregard of the duties of his or her office or employment.

Section 7. Dividends.
