Seymore v. Metson Marine opinion amended after rehearing

The Court of Appeal (First Appellate District, Division Three), issued its initial opinon in Seymore v. Metson Marine, Inc. on February 28, 2011).  Today, the Court issued an ameded opinion.  Seymore v. Metson Marine, Inc. (April 15, 2011).  I haven't had a chance to compare the opinions, so I'm not sure whether the opinion changed in any substantive way, or whether the Court simply addressed additional points raised during rehearing.  The opinion is four pages longer; however, the Court's reversal of the trial court remains in place.
