We revisit the calculation of nonfactorizable contributions induced by charm-quark loops to the amplitudes of exclusive FCNC B-decays. Nonfactorizable contributions may be expressed via the three-particle quark-antiquark-gluon distribution amplitude (3DA) of the B-meson ⟨0|q̄(x)Gμν(y)b(0)|B(p)⟩. We show that the knowledge of the full generic 3DA with non-aligned arguments, is necessary for a proper summation of large ( ΛQCDmb/mc )n corrections. In particular, the dependence of 3DA on variable (x − y)2 is crucial.
