PHP - How To Add An Addtional Count Per 4 Items

I would like to add another count that after every 4 items, it loops and create  a added piece of script, by adding <ul><li> tags after every 4 items.

I want to addthis piece of code, every fours items after it close </div>

Code: [Select]
            <ul>
               <li>
                <div class="box">
             <!--All fields and information here-->
                </div>
               <div class="h2"></div>
                <div class="box">
             <!--All fields and information here-->
                </div>
               <div class="h2"></div>
                <div class="box">
             <!--All fields and information here-->
                </div>
               <div class="h2"></div>
                <div class="box">
             <!--All fields and information here-->
                </div>
               <div class="h2"></div>
                   </li>
              </ul>

I currently have this piece of code, which builds a list per every <div class="box">, then closes the item </div> and start another one as same.
SEE current CODE.
Code: [Select]

 <?php
    $dealList = $this->dealList;
    if(count($dealList)==0) echo '<h3>'.JText::_('NO_DEAL_MESSAGE').'</h3>';
$count = 1; 
foreach ( $dealList as $row): 
$link = 'index.php?xxx=' . $row->id;
if(!Helper::is_urlEncoded($row->pic_dir))
 {
  $imageUrl = $row->pic_dir;
 }
 else
 {
$imageUrlArr= unserialize(urldecode($row->pic_dir));
$imageUrl = str_replace("\\","/",$imageUrlArr[0]);
 }
?>

<div class="box">
information fields here
</div>


  <?php if ($count%2==1){?>
     <div class="h2"></div>
    <?php }
    else if($count%2==0){?>
    <div class="h3"></div>
   <?php  }$count++ ; endforeach;?>

How do I added the Additonal count for efter four items <div class=box"> it places and start over with
Code: [Select]
<ul>
  <li>
     <div class="box">
      information fields
     </div>
 </li>
</ul>
