<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On February&nbsp;4, 2008, the Reporting Person filed, with the Securities Exchange Commission, a
preliminary proxy statement (the &#147;Proxy Statement&#148;) nominating himself, Lloyd I. Miller, III, to be
elected by the common stockholders to the Board of Directors of the Company. Mr.&nbsp;Miller intends to
solicit proxies from the holders of shares of the Company&#146;s common stock, in favor of his election,
to be used at the 2008 Annual Meeting of Stockholders of the Company. The Reporting Person
proposes the election of himself, Lloyd I. Miller, III, for the purpose of diversifying the current
Board of Directors with a new, independent, shareholder-nominated director who will seek to
maximize shareholder value and further the goals of all public stockholders of the Company. For
additional information regarding Lloyd I. Miller, III and his proxy solicitation, see the Proxy
Statement.
