Alternate coloured Row Issue

My xml is as follows:

<products>
               <product>
                 <productID>1</productID>
                 <name>Motorcyle</name>
                 </product>
                 <product>
                 <productID>2</productID>
                 <name>Accessories</name>
                 </product>
                  ..........
</products>

My xsl allows for the products to be displayed on alternate coloured lines:

<xsl:template match="product[position() mod 2 = 1]">
        <tr class="odd">
                 <td>

                 <div align="center">
			<a> <xsl:attribute name="href">product.jsp?productID=<xsl:value-of
select="productID"/>&amp;secondhtml=<xsl:value-of select="$secondhtml"/>
           </xsl:attribute>
             <b> <font face="Verdana, Arial, Helvetica, sans-serif">

                <xsl:value-of select="name"/>
               </font>   </b>
             </a>
             </div>
             </td>
            </tr>
  </xsl:template>

<xsl:template match="product">
       <tr class="even">
                 <td>
                 <div align="center">
			<a> <xsl:attribute name="href">product.jsp?productID=<xsl:value-of
select="productID"/>&amp;secondhtml=<xsl:value-of select="$secondhtml"/>
           </xsl:attribute>
             <b> <font face="Verdana, Arial, Helvetica, sans-serif">

                <xsl:value-of select="name"/>
               </font>   </b>
             </a>
             </div>
            </td>
            </tr>
  </xsl:template>

My problem relates to incorporating an independent last row, and making it
follow the same colour pattern:
<tr>
          <td>
            <div align="center">
              <a>
		  <xsl:attribute name="href"><xsl:value-of
select="$email"/></xsl:attribute>
		  <b><font size="3" face="Verdana, Arial, Helvetica, sans-serif">Contact
              Us</font></b>
	      </a>

           </div>
          </td>
 </tr>

E.G
if odd=red and even=blue

if there were 4 products you would expect:
        row 1 (red) Motorcyles
        row 2 (blue) Accessories
        row 3 (red) Clothing
        row 4 (blue) Cars
       row 5 (red) Contact Us <!-- here is the problem-->

if there were 3 products then you would expect:
       row 1 (red) Motorcyles
        row 2 (blue) Accessories
        row 3 (red) Clothing
        row 4 (blue) Contact Us <!-- here is the problem-->

Thanks.
