did you try

<div class="alt1 block_row">
<ul class="list_no_decoration">
	$block_data[fields]
</ul>
</div>
<br /><br />
<div class="thead block_row">$vbphrase[signature]</div>
<div class="alt1 block_row">
	<if condition="$prepared['signature']">
		<dl class="list_no_decoration profilefield_list"><dd id="signature">$prepared[signature]</dd></dl>
	</if>
</div>

i didn't try it, but it looks like it'd make sense?
