changed a file without backup function.php

I am using the Expound theme in wordpress and changed the fuction.php file trying to change the footer. Now I am getting the message

Parse error: syntax error, unexpected T_CLASS in /home/content/27/11058027/html/bellferro/dev/wp-content/themes/expound/functions.php on line 264

Does anyone know what I can do to fix this. The following is the code I need to fix. I can’t even sign into my wordpress anymore. Thanks in advance.

/**
* Footer credits.
*/
function expound_display_credits() {
$text = ‘Bellferro Ironworks | Custom Iron Designs’ ;
$text = ‘<span class=”sep”> | </span>’;
$text = ’29 Ridge Road West’;
$text = ‘Grimsby,ON’;
$text = ‘905-401-3001’;
echo apply_filters( ‘expound_credits_text’, $text );
}
add_action( ‘expound_credits’, ‘expound_display_credits’ );
