Click inside the second block of text (paragraph beginning: 'Depending on your specific needs . . . ) and in the CSS Styles panel change 'font-size' from '110%' to '12px'. That should sort it out.
Alternatively, find the line (somewhere around line 200) and change it there:
<div style="line-height: 150%; float:left; width:269px; font-size: 110%; font-family: Arial, Helvetica, sans-serif;">
to
<div style="line-height: 150%; float:left; width:269px; font-size: 12px; font-family: Arial, Helvetica, sans-serif;">
