an explosive; or when such explosion or fire 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 vehicle at the time; and (c) the defendant knows that
fact or the circumstances are such as to render the presence of such
