<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
Bylaws provide that we may voluntarily indemnify any individual made a party to a proceeding because he is or was our director, officer, employee or agent against liability incurred
in the proceeding, but only if we have authorized the payment in accordance with the applicable statutory provisions of the Utah Revised Business Corporation Act (Sections
16-10a-902, 16-10a-904 and 16-10a-907) and a determination has been made in accordance with the procedures set forth in such
provision that such individual conducted himself in good faith, that he reasonably believed his conduct, in his official capacity with us, was in our best interests and that his conduct, in all other
cases, was at least not opposed to our best interests, and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding. The foregoing indemnification in
connection with a proceeding by or in the right of us is limited to reasonable expenses incurred in connection with the proceeding, which expenses may be advanced by us. Our Bylaws provide that we may
not voluntarily indemnify our director, officer, employee or agent in connection with a proceeding by or in the right of us in which such individual was adjudged liable to us 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. </FONT></P>

Item 6. Indemnification of Directors and Officers
Reference is made to Section 16-10a-901 of the Utah Revised Business Corporation Act, which provides for indemnification of
directors and officers in certain circumstances.
Our
Bylaws provide that we may voluntarily indemnify any individual made a party to a proceeding because he is or was our director, officer, employee or agent against liability incurred
in the proceeding, but only if we have authorized the payment in accordance with the applicable statutory provisions of the Utah Revised Business Corporation Act (Sections
16-10a-902, 16-10a-904 and 16-10a-907) and a determination has been made in accordance with the procedures set forth in such
provision that such individual conducted himself in good faith, that he reasonably believed his conduct, in his official capacity with us, was in our best interests and that his conduct, in all other
cases, was at least not opposed to our best interests, and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding. The foregoing indemnification in
connection with a proceeding by or in the right of us is limited to reasonable expenses incurred in connection with the proceeding, which expenses may be advanced by us. Our Bylaws provide that we may
not voluntarily indemnify our director, officer, employee or agent in connection with a proceeding by or in the right of us in which such individual was adjudged liable to us 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.
Our
Bylaws provide further that we shall indemnify our director, officer, employee or agent who was wholly successful, on the merits or otherwise, in defense of any proceeding to which
he was a party because he is or was such a director, officer, employee or agent, against reasonable expenses incurred by him in connection with the proceeding.
Our
Bylaws further provide that no director of ours shall be personally liable to us or our stockholders for monetary damage 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 us 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.
We
maintain insurance on behalf of our officers and directors pursuant to which (subject to the limits and limitations of such insurance) the officers and directors are insured against
certain expenses in connection with the defense of actions or proceedings, and certain liabilities which might be imposed as a result of such actions or proceedings, to which any of them is made a
party by reason of being or having been a director or officer.
