either (i) causes serious physical injury to another person other
than a participant, or (ii) the explosion or fire was caused with
the  expectation  or  receipt of financial advantage or pecuniary
profit by the actor; and when (b) another person  who  is  not  a
participant  in  the  crime  is present in such building or motor
