INDEMNIFICATION AND INSURANCE SECTION 47.  (a)  Voluntary Indemnification.  Unless otherwise provided in the Articles of Incorporation, the Corporation shall indemnify any individual made a party to a proceeding because he is or was a director of the Corporation, against liability incurred in the proceeding, but only if the Corporation has authorized the payment in accordance with the applicable statutory provisions [Sections 16-10a-902 and 16-10a-904 of Utah's Revised Business Corporation Act] and a determination has been made in accordance with the procedures set forth in such provision that the director conducted himself in good faith; that he reasonably believed that his conduct, if in his official capacity with the Corporation, was in its best interests   13  and that his conduct, in all other cases, was at least not opposed to the Corporation's best interests; and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding. (b)  The Corporation may not voluntarily indemnify a director in connection with a proceeding by or in the right of the Corporation in which the director was adjudged liable to the Corporation or in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him. (c)  Indemnification permitted under Paragraph (a) in connection with a proceeding by or in the right of the Corporation is limited to reasonable expenses incurred in connection with the proceeding. (d)  If a determination is made, using the procedures set forth in the applicable statutory provision, that the director has satisfied the requirements listed herein and if an authorization of payment is made, using the procedures and standards set forth in the applicable statutory provision, then, unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if the director furnishes the Corporation a written affirmation of his good faith belief that he has satisfied the standard of conduct described in this Section, furnishes the Corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct (which undertaking must be an unlimited general obligation of the director, but need not be secured and may be accepted without reference to financial ability to make repayment); and if a determination is made that the facts then known of those making the determination would not preclude indemnification under this Section. (e)  Mandatory Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall indemnify a director or officer of the Corporation who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he   14  is or was a director or officer of the Corporation against reasonable expenses incurred by him in connection with the proceeding. (f)  Court-Ordered Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, a director or officer of the Corporation who is or was a party to a proceeding may apply for indemnification to the court conducting the proceeding or to another court of competent jurisdiction.  The court may order indemnification if it determines that the director or officer is entitled to mandatory indemnification as provided in this Section and applicable law, in which case the court shall also order the Corporation to pay the reasonable expenses incurred by the director or officer to obtain court-ordered indemnification.  The court may also order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not the director or officer met the applicable standard of conduct set forth in this Section and applicable law.  Any indemnification with respect to any proceeding in which liability has been adjudged in the circumstances described in Paragraph (b) above is limited to reasonable expenses. (g)  Indemnification of Others.  Unless otherwise provided in the Corporation's Articles of Incorporation, an officer, employee, or agent of the Corporation shall have the same indemnification rights provided to a director by this Section.   The Board of Directors may also indemnify and advance expenses to any officer, employee, or agent of the Corporation, to any extent consistent with public policy as determined by the general or specific purpose of the Board of Directors. (h)  Insurance.  The Corporation may purchase and maintain liability insurance on behalf of a person who is or was a director, officer, employee, fiduciary, or agent or the Corporation, or who, while serving as a director, officer, employee, fiduciary, or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, trustee, employee, fiduciary or agent of another foreign or domestic corporation, other person, of an employee benefit plan, or incurred by him in that capacity or arising from his status as a director, officer, employee, fiduciary, or agent, whether or not the Corporation has the power to indemnify him against the same liability under applicable law.   15  LIMITATION ON LIABILITY SECTION 48.  No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any action taken or any failure to take any action, as a director, except liability for (a) the amount of a financial benefit received by a director to which he is not entitled; (b) an intentional infliction of harm on the Corporation or the shareholders; (c) for any action that would result in liability of the director under the applicable statutory provision concerning unlawful distributions or (d) an intentional violation of criminal law.  This provision shall not limit the liability of a director for any act or omission occurring prior to August 11, 1992.  Any repeat or modification of this provision by the stockholders shall be prospective only and shall not adversely affect any limitation on the personal liability of a director for the Corporation for acts or omissions occurring prior to the effective date of such repeal or modification.      16
