<P style="font-size: 10pt" align="justify">On September&nbsp;18, 2008, the Board of Directors of the Corporation voted
to merge the two stock repurchase programs of the Corporation, and authorized the allocation of an additional $500,000

its shares in individually negotiated transactions from time to time as shares become available. The Corporation will
fund purchases under the repurchase program from available working capital. The stock repurchase program does not
require the Corporation to acquire any specific number of shares and may be modified, suspended, extended or terminated
by the Corporation at any time without prior notice. The repurchase program will terminate on December&nbsp;31, 2008
unless earlier suspended or discontinued by the Corporation. As of September&nbsp;23, 2008, $361,343 was available for
the repurchase of shares under the stock repurchase program.
