Fixing Neatline Incompatability Problem

How do I fix this?
Warning: Declaration of NeatlineExhibit::beforeSave() should be compatible with Omeka_Record_AbstractRecord::beforeSave($args) in /home/norumbe1/public_html/plugins/Neatline/models/NeatlineExhibit.php on line 10

Do I need to go into the PHP, or is there a solution that I can apply to solve this incompatibility issue?
