class style for excerpt

I’m trying to make the excerpt look different when displayed in the complete article.
I managed so far to pull the excerpt and make it different, the problem is it repeats when pulling the content.
What is the way of displaying the content without the excerpt?

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
	<a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a>
<div class="EXCERPT_STYLE">
	<?php the_excerpt(); ?></div>
	<?php the_content($more_link_text , $strip_teaser, $more_file );?>
