Hyperlink Inside of Array

Hello,

I’m in the middle of editing the WP Nivo Slider plugin (the free one) to customize the title. I am having the following problem, though:
I want to link the title that is inside of $thumb_attr array, but I can’t seem to figure it out. :/ I don’t know much about PHP, so I am fumbling my way through this.

The code for the plugin is as follows:

<div id="slider">
<?php
	$category = get_option('wpns_category');
	$n_slices = get_option('wpns_slices');
?>
<?php query_posts( 'cat='.$category.'&posts_per_page='.$n_slices.'' ); if( have_posts() ) : while( 

have_posts() ) : the_post(); ?>
	<?php if(has_post_thumbnail()) : ?>
	<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
		<?php $thumb_attr = array(
				'title' => '<h3>' . '<a href="THIS IS WHERE LINK SHOULD GO">' . get_the_title() . '</a>' . '</h3>' . '<h4>' . get_the_excerpt() . '</h4>'
		); ?>
		<?php the_post_thumbnail('featured-thumbnail', $thumb_attr );  ?>
</a>
	<?php endif ?>
	<?php endwhile; endif;?>
	<?php wp_reset_query();?>
</div>
