This is closer to how PSL would represent it.
(Buttering j t) would be a term denoting the activity that is the 
buttering of toast t by agent j:
(forall (j t)
(if (and (agent j)
            (toast t))
     (activity (Buttering j t))))    (04)

To represent the "slowly", one could quantify over occurrences of the 
activity:
(exists (j t o)
(and (occurrence_of o (Buttering j t))
        (lesser D (duration_of ?o))))
where D would be some constant capturing your idea of "slowly".    (05)
