hide post on home page

I’m still a little unsure of how I would modify it to exclude posts from category ID 2 on my home page only.

Here is my loop that I think I need to modify:

function thesis_home_loop() {
	$post_count = 1;
	$teaser_count = 1;

	while (have_posts()) {
		the_post();

		if (thesis_is_teaser($post_count)) {
			if (($teaser_count % 2) == 1) {
				$top = ($post_count == 1) ? ' top' : '';
				$open_box = '			<div class="teasers_box' . $top . '">' . "\n\n";
				$close_box = '';
				$right = false;
			}
			else {
				$open_box = '';
				$close_box = '			</div>' . "\n\n";
				$right = true;
			}

			if ($open_box != '') {
				echo $open_box;
				thesis_hook_before_teasers_box($post_count);
			}

			thesis_teaser($classes, $post_count, $right);

			if ($close_box != '') {
				echo $close_box;
				thesis_hook_after_teasers_box($post_count);
			}

			$teaser_count++;
		}
		else {
			$classes = 'post_box';

			if ($post_count == 1)
				$classes .= ' top';

			thesis_post_box($classes, $post_count);
		}

		$post_count++;
	}

	if ((($teaser_count - 1) % 2) == 1)
		echo '			</div>' . "\n\n";
}

could you help me out?
