Excluding a category

Hi. I want to hide certain categories from being shown, by editing the code below:

<footer class="entry-meta">
		<?php
			/* translators: used between list items, there is a space after the comma */
			$categories_list = get_the_category_list(__( ', ', 'catchbox' ) );

			/* translators: used between list items, there is a space after the comma */
			$tag_list = get_the_tag_list( '', __( ', ', 'catchbox' ) );
			if ( '' != $tag_list ) {
				$utility_text = __( '<b>Region:</b> %1$s &nbsp; | &nbsp; <b>Branche:</b> %2$s', 'catchbox' );
			} elseif ( '' != $categories_list ) {
				$utility_text = __( '<b>Region:</b> %1$s &nbsp; | &nbsp; <b>Branche:</b> %2$s', 'catchbox' );
			} else {
				$utility_text = __( '<b>Region:</b> %1$s &nbsp; | &nbsp; <b>Branche:</b> %2$s', 'catchbox' );
			}

			printf(
				$utility_text,
				$categories_list,
				$tag_list,
				esc_url( get_permalink() ),
				the_title_attribute( 'echo=0' ),
				get_the_author(),
				esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) )
			);
		?>

I know I can do something along the lines of this:
<?php wp_list_categories('orderby=name&show_count=1&exclude=5'); ?>
but I’m not sure where to put it in the above code for it to work.

Can someone help?
