Recently, Neubert has suggested that a certain class of nonperturbative corrections dominates the shape of the electron spectrum in the end point region of semileptonic [ital B] decay. Perturbative QCD corrections are important in the end point region. We study the effects of these corrections on Neubert's proposal. A connection between the end point of the electron spectrum in semileptonic [ital B] decay and the photon spectrum in [ital b][r arrow][ital s][gamma] is outlined.
