CASH DIVIDEND</font></b></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">LAREDO, TX,&nbsp;&nbsp;October 2, 2006&nbsp;-
International Bancshares Corporation (&#147;IBC&#148;) today announced that the Board of
Directors approved the declaration of a <b><font style="font-weight:bold;">35</font> cents</b> per share cash dividend,
for shareholders of record as of the close of business on October 16, 2006,
payable on November 1, 2006.&#160;&#160; &#147;This cash
dividend was made possible because of the strong performance of IBC for 2006&#148;,
said Dennis E. Nixon, Chairman and President of IBC.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">It is the inclination of the Board to continue to
declare semiannual cash dividends.&#160;
However, any declaration of future cash dividends will depend upon IBC&#146;s
financial position, acquisition opportunities, and general business conditions
at the time.</font></p>

billion multi-bank financial holding company headquartered in Laredo, Texas,
