Need help with a theme

Hi All,
I’m working on a site and it’s pulling the excerpt for a post which is causing there to be no breaks in the text. The client wants to show the natural breaks, but I’m not familiar with the coding for this theme.

These are the arrays the theme calls. Does anyone know how to add one for the post?

$arr[$i]["title"] = truncate_title(50,false);
$arr[$i]["title_small"] = truncate_title(25,false);

$arr[$i]["fulltitle"] = truncate_title(250,false);

$arr[$i]["excerpt"] = truncate_post(260,false);
$arr[$i]["excerpt_small"] = truncate_post(80,false);

$arr[$i]["tagline"] = get_post_meta($post->ID, 'Tagline', $single = true);
$arr[$i]["permalink"] = get_permalink();

$arr[$i]["thumbnail"] = get_thumbnail($width,$height,'thumb',$arr[$i]["fulltitle"],$arr[$i]["tagline"]);
$arr[$i]["thumb"] = $arr[$i]["thumbnail"]["thumb"];
$arr[$i]["thumbnail_small"] = get_thumbnail($width_small,$height_small,'',$arr[$i]["fulltitle"],$arr[$i]["tagline"]);
$arr[$i]["thumb_small"] = $arr[$i]["thumbnail_small"]["thumb"];

$arr[$i]["use_timthumb"] = $arr[$i]["thumbnail"]["use_timthumb"];
