exclude category in sidebar of mimbo script

Hi, have a nice day!

I am implementing my blog using Mimbo 3. In sidebar.php have a nice code. This show “more from this category”…the next is the code:

<!–BEGIN ‘MORE FROM THIS CATEGORY’–>
<?php
if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
$posts = get_posts(‘numberposts=4&exclude=’ . $GLOBALS[‘current_id’] . ‘&category=’. $category->term_id);
if(count($posts) > 1) {
?>

<div class=”widget”>
<h3><?php _e(‘More in’,’Mimbo’); ?> ‘<?php echo $category->name; ?>'</h3>

<?php foreach($posts as $post) : ?>

• “><?php the_title(); ?>

<?php endforeach; ?>

</div>

<?php } ?>

<?php endforeach; ?>
<?php endif; ?>

<!–END–>

My questions is… How do I exclude certain categories of results that show? Please Help Me…

Tanks a lot,

Pavel
