<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td valign="top" align="right" width="35" style="line-height: 18px;">

</td>
<td valign="middle" style="line-height: 18px;">
<span style="font: 10pt Arial, Sans-Serif; color: #444444; line-height: 18px;">This is bullet №1</span>

<tr>
<td height="5" colspan="2" style="border-collapse: collapse;">
<div style="margin: 0; padding: 0; line-height: 0;">
<img src="indent.gif" border="0" width="1" height="1"
style="display: block;" alt="" />
