and execute, for and on behalf of the undersigned, such documents as may be
required from time to time by Section&nbsp;16 of the Securities Exchange Act of
1934, as amended, and rules thereunder (collectively, the &#8220;Exchange
Act&#8221;);

<P style="font-size: 10pt; text-indent: 4%" align="justify">(2)&nbsp;do and
perform any and all acts for and on behalf of the undersigned which may be
necessary or desirable to comply with the requirements of Section&nbsp;16 of
the Exchange Act including, but not limited to, executing documents required by
such section and effecting the timely filing thereof with the United States
Securities and Exchange Commission and any stock exchange or similar authority;
and

<P style="font-size: 10pt; text-indent: 4%" align="justify">(3)&nbsp;take any
other action of any type whatsoever in connection with the foregoing which, in
the opinion of such attorney-in-fact, may be of benefit to, in the best
interest of, or legally required by, the undersigned, it being understood that
the documents executed by such attorney-in-fact on behalf of the undersigned
pursuant to this Power of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve in his discretion.

<P style="font-size: 10pt; text-indent: 4%" align="justify">The undersigned
hereby grants to such attorney-in-fact full power and authority to do and

undersigned, is not assuming any of the undersigned&#8217;s responsibilities to

<P style="font-size: 10pt; text-indent: 4%" align="justify">This Power of
Attorney shall remain in full force and effect until the undersigned is no
