Custom List_Page Function How to Excluse Pages?

I have this theme and it uses a custom function to list pages, therefor I can’t excluse pages with the usual excluse or plugin. How can I excluse a page using this custom fs_list_pages function?

# Displays a list of pages
$fs_first = true;
function fs_list_pages($parent=0) {
	global $fs_first;
	$pages = fs_get_pages($parent);
	if (count($pages)>0) {
		?><ul><?php
		if ($fs_first) {
			?><li class="f"><a href="<?php echo get_option('home'); ?>">ACCEUIL</a></li><?php
			$fs_first = false;
		}
		foreach ($pages as $page) {
			if ($page->id>0) {
				?><li><a href="<?php echo get_permalink($page->id); ?>"><?php echo $page->title; ?><?php if (fs_has_subpages($page->id)) echo ' &raquo;'; ?></a>
				<?php $count = fs_list_pages($page->id); ?>
				</li><?php
			}
						if ($page->id>0) {
				?><?php
			}
		}
		?></ul><?php
	}
	$count++;
	return $count;
}
