  Heavy quark production in five jet events at $e^+e^-$ colliders is studied at
tree level using helicity amplitudes. Total production rates for $2b3j$ and
$4bj$ are given and compared with the corresponding results for massless
quarks. The process $e^+e^-\rightarrow q\bar q gg\gamma$ which is the dominant
contribution to $4j\gamma$ production is briefly discussed.
