</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On April&nbsp;13, 2007, the Audit Committee of the Company&#146;s Board of Directors and the Company&#146;s
management concluded that the consolidated financial statements for the first quarter of fiscal
2007 ended December&nbsp;31, 2006 and for the eleven-month transition period ended September&nbsp;30, 2006
and one or more fiscal quarters in such transition period should no longer be relied upon due to
certain accounting errors found at one of its divisions. The Company is diligently evaluating the
impact of these accounting errors on its previously filed financial statements and continuing the
process of restating the financial statements included in, and preparing amendments to, the
relevant Exchange Act reports it previously filed.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a result of the errors and restatements discussed above, the time required to amend the
relevant Exchange Act reports and the effect of such restatements on the consolidated financial
statements to be included in the quarterly report for the quarter ended March&nbsp;31, 2007, we were
unable to prepare and file our quarterly report on Form 10-Q for the quarter ended March&nbsp;31, 2007
within the time period prescribed by Rule&nbsp;13a-13 of the Securities Exchange Act of 1934. We plan
to file our quarterly report on Form 10-Q for the quarter ended March&nbsp;31, 2007 as soon as
practicable. We are still assessing whether such errors were the
result of a material weakness in our internal controls over financial
reporting.
