<P align="left" style="margin-left:2%; font-size: 10pt; text-indent: 3%">Argyle
Security, Inc. (the &#147;Company&#148;) had revenues of $86.8&nbsp;million (including related party revenues of
$1.9&nbsp;million) and $105.8&nbsp;million (including related party revenues of $15.1&nbsp;million) for the nine months ended
September&nbsp;30, 2009 and 2008, respectively, representing a
decrease of $19.0&nbsp;million or 18.1%. The decrease in 2009
was because in 2008, the Company&#146;s Corrections business segment saw significant revenue growth due to an increase
in the number of projects booked during 2007 when the U.S. economy was more robust. During 2008, the number of
projects booked was lower because of the overall slowdown of the U.S. economy and a more challenging
debt-financing market for larger private prison developers. The fewer projects booked resulted in lower revenues
for the nine months ended September&nbsp;30, 2009.



<P align="left" style="margin-left:2%; font-size: 10pt; text-indent: 3%">Because of the ongoing work being done by the Company to finalize the financial results, a reasonable
estimate of the cost of revenues, gross margin, operating expenses, other income and net income cannot be made at
this time.
