(See facts in previous case). We hereby grant petitioner's suggestion for rehearing en banc. We do not, however, vacate the panel's opinion and order dated December 31, 1986. 820 F.2d 1342. Rather, we issue the attached en banc opinion as an addendum to, and modification of, said panel opinion; and as so modified said panel opinion and order may stand as reflecting the opinion of the en banc court.
