View in feature.php tag instead of category

My theme, displays featured.php in a given category would change that to a certain tag.

The post would be in focus would only have this tag

The code of my feature.php and this:

<?php

	$showfeatured = get_option('woo_show_featured');
   if ( $showfeatured ) { 

?>

<div class="box">

    <div class="top"></div>

    <div class="spacer"> 

    	<div id="arrows">
			<a id="prev2" href="#"><img src="<?php bloginfo('template_directory'); ?>/images/left-bar.gif" alt="" class="fl" /></a>
    		<a id="next2" href="#"><img src="<?php bloginfo('template_directory'); ?>/images/right-bar.gif" alt="" class="fr" /></a>
    	</div><!--/arrows -->

    	<div class="featuredpost">

			<?php 

				$showfeatured = get_option('woo_featured_entries'); // Number of other entries to be shown
				include(TEMPLATEPATH . '/includes/version.php');

				$the_query = new WP_Query('cat=' . $ex_feat . '&showposts=' . $showfeatured . '&orderby=post_date&order=desc');
				$wp_query->in_the_loop = true; // Need this for tags to work

				while ($the_query->have_posts()) : $the_query->the_post(); $do_not_duplicate = $post->ID;
			?>

            <div class="featureditem">

                <div class="col4">
                    <img src="<?php echo bloginfo('template_url'); ?>/thumb.php?src=<?php echo get_post_meta($post->ID, "image", $single = true); ?>&amp;h=210&amp;w=310&amp;zc=1&amp;q=95" alt="<?php the_title(); ?>" />
                </div>

                <div class="col5">

                    <h2><a title="Permanent Link to <?php the_title(); ?>" href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>
                    <div class="date-comments">
                        <p class="fl"><?php the_time('l, F j, Y'); ?></p>
                        <p class="fr"><span class="comments"></span><?php comments_popup_link('0 Comments', '1 Comment', '% Comments'); ?></p>
                    </div>

                    <p class="content"><?php echo strip_tags(get_the_excerpt(), '<a><strong>'); ?></p>

                    <div class="continue-tags">
                        <p class="fl"><a title="Permanent Link to <?php the_title(); ?>" href="<?php the_permalink() ?>">Continue reading...</a></p>
                        <p><?php the_tags('<span class="fr tags">', ', ', '</span>'); ?></p>

                    </div>    	

                </div><!--/col5 -->		

            </div>

			<?php endwhile; ?>

		</div><!--/featuredpost -->

        <div class="fix"></div>

    </div><!--/spacer -->

    <div class="bot"></div>

</div><!--/box -->

<?php

	}

?>

How do I change it drops show only a specific tag instead of a category
