SHARES

Section 5-1     Certificates and Transfers. The interest of each shareholder of the Corporation shall be evidenced by certificates for shares of stock in such form as the appropriate officers of the Corporation may from time to time prescribe or by uncertificated or electronic shares. The shares of the stock of the Corporation shall be entered in the books of the Corporation as they are issued and shall exhibit the holder’s name and number of shares. Subject to the provisions of the Articles of Incorporation, the shares of the stock of the Corporation shall be transferred on the books of the Corporation, which may be maintained by a third-party registrar or transfer agent, by the holder thereof in person or by his attorney, upon surrender for cancellation of certificates for at least the same number of shares, with an assignment and power of transfer endorsed thereon or attached thereto, duly executed, with such proof of the authenticity of the signature as the Corporation or its agents may reasonably require or upon receipt of proper transfer instructions from the registered holder of uncertificated shares and upon compliance with appropriate procedures for transferring shares in uncertificated form, at which time the Corporation shall issue a new certificate to the person entitled thereto (if the stock is then represented by certificates), cancel the old certificate and record the transaction upon its books. The Board shall have the power and authority to make all such rules and regulations as it may deem expedient concerning the issue, transfer and registration or the replacement of certificates for shares of stock of the Corporation. The Corporation may enter into additional agreements with shareholders to restrict the transfer of stock of the Corporation in any manner not prohibited by the Act.

Each certificated share of stock shall be signed, countersigned and registered by the President and Secretary, or such other manner as the Board may by resolution prescribe. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate has ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.

Section 5-2     Lost or Destroyed Certificates. No certificate for shares or uncertificated shares of stock in the Corporation shall be issued in place of any certificate alleged to have been lost, destroyed or stolen, except on production of such evidence of such loss, destruction or theft and on delivery to the Corporation of a bond of indemnity in such amount, upon such terms and secured by such surety, as the Board or any financial officer of the Corporation may in its or his/her discretion require.

Section 5-3     Transfer of Shares.

Transfer of uncertificated shares of stock shall be upon receipt of proper transfer instructions from the registered owner of the uncertificated shares, an instruction from an approved source duly authorized by such owner, or from an attorney lawfully constituted in writing. The Corporation may impose such additional conditions to the transfer of shares of its stock as may be necessary or appropriate for compliance with applicable law or to protect the Corporation, a transfer agent or the registrar from liability with respect to such transfer.

Section 5-3-2     The Corporation shall be entitled to treat the holder of record of any share as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such share on the part of any other person whether or not it shall have express or other notice thereof, except as expressly provided by the laws of Colorado.

DIVIDENDS

Except as otherwise provided by law or the Articles of Incorporation, the Board may from time to time declare, and the Corporation may pay, dividends on its outstanding shares of stock, which dividends may be paid in either cash, property or shares of stock of the Corporation. A member of the Board shall be fully protected in relying in good faith upon the records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of its officers or employees, or committees of the Board, or by any other person as to matters the Director reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation, as to the value and amount of the assets, liabilities or net profits of the Corporation, or any other facts pertinent to the existence and amount of surplus or other funds from which dividends might properly be declared and paid.

The Board may fix in advance a future date which precedes the date for the payment to shareholders of any dividend, or the date for the distribution or allotment of rights, or the date when any change, conversion or exchange of capital stock shall go into effect, as a record date for the determination of shareholders entitled to receive payment of any such dividend, or to receive any distribution or allotment of such rights, or to exercise the rights in respect of any such change, conversion or exchange or capital stock, and in such case only such shareholders as shall be shareholders of record on the date so fixed shall be entitled to receive payment of such dividend, or to receive such distribution or allotment of rights, or to exercise any stock on the books of the Corporation after any such record date fixed as aforesaid

INDEMNIFICATION AND ADVANCEMENT OF EXPENSES

Section 8-1     Indemnification and Advancement of Expenses.

Section 8-1-1     The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that he, she, or a person for whom they are the legal representative, is or was a member of the Board of the Corporation or an officer of the Corporation elected or appointed by resolution of the Board of Directors, or, while a Director or such an officer of the Corporation, is or was serving at the request of the Corporation as a Director, officer, employee or agent of another Corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (a “Covered Individual”), whether the basis of such proceeding is alleged action in an official capacity as a Director, officer, employee or agent, or in any other capacity while serving as a Director, officer, employee or agent, against all expenses, liability and loss (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by such Covered Individual in connection with such proceeding.

Section 8-1-2     The Corporation shall, to the fullest extent not prohibited by applicable law as it presently exists or may hereafter be amended, before the final disposition of a proceeding pay the expenses (including attorneys’ fees) incurred by a Covered Individual in defending any proceeding; provided, however, that to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding must be made only upon receipt of an undertaking by the Covered Individual to repay all amounts advanced if it should be ultimately determined that the Covered Individual is not entitled to be indemnified under this Section 8-1 or otherwise.

Section 8-1-3     The rights to indemnification and advancement of expenses under this Section 8-1 are contract rights and such rights shall continue as to a Covered Individual who has ceased to be a Director, officer, employee or agent and shall inure to the benefit of his heirs, executors and administrators. Notwithstanding the foregoing provisions of this Section 8-1, except for proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to a Covered Individual in connection with a proceeding (or part thereof) initiated by such Covered Individual only if such proceeding (or part thereof) was authorized by the Board.

-15-

Section 8-1-4     If a claim for indemnification under this Section 8-1 (following the final disposition of such proceeding) is not paid in full within 60 days after the Corporation has received a claim by the Covered Individual, or if a claim for any advancement of expenses under this Section 8-1 is not paid in full within 30 days after the Corporation has received a statement or statements requesting such amounts to be advanced, the Covered Individual shall thereupon (but not before) be entitled to file suit to recover the unpaid amount of such claim. If successful in whole or in part, the Covered Individual shall be entitled to be paid the expense of prosecuting such claim to the fullest extent permitted by applicable law. In any such action, the Corporation shall have the burden of proving that the Covered Individual is not entitled to the requested indemnification or advancement of expenses under applicable law.

Section 8-1-5     The rights conferred on any Covered Individual by this Section 8-1 shall not be exclusive of any other rights that such Covered Individual may have or hereafter acquire under any statute, any provision of the Articles of Incorporation, these Bylaws, any agreement or vote of shareholders or disinterested Directors or otherwise.

Section 8-1-6     This Section 8-1 shall not limit the right of the Corporation, to the extent and in the manner permitted by applicable law, to indemnify and to advance expenses to persons other than Covered Individual when and as authorized by appropriate corporate action.
