<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Section&nbsp;78.138 of the Nevada Revised Statute
provides that a director or officer is not individually liable to the corporation or its stockholders or creditors for any damages as
a result of any act or failure to act in his capacity as a director or officer unless it is proven that (1)&nbsp;his act or failure to
act constituted a breach of his fiduciary duties as a director or officer and (2)&nbsp;his breach of those duties involved intentional
misconduct, fraud or a knowing violation of law.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">This provision is intended to afford directors
and officers protection against and to limit their potential liability for monetary damages resulting from suits alleging a breach of
the duty of care by a director or officer. As a consequence of this provision, stockholders of our company will be unable to recover monetary
damages against directors or officers for action taken by them that may constitute negligence or gross negligence in performance of their
duties unless such conduct falls within one of the foregoing exceptions. The provision, however, does not alter the applicable standards
governing a director&rsquo;s or officer&rsquo;s fiduciary duty and does not eliminate or limit the right of our company or any stockholder
to obtain an injunction or any other type of non-monetary relief in the event of a breach of fiduciary duty.</P>

to the fullest extent permitted by Nevada law (as amended from time to time). Section&nbsp;78.7502 of the Nevada Revised Statute provides
that such indemnification may only be provided if the person acted in good faith and in a manner he or she reasonably believed to be in,
or not opposed to, the best interest of the Registrant and, with respect to any criminal action or proceeding, had no reasonable cause

unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of
expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action,
