  We apply the method of QCD light-cone sum rules to calculate nonfactorizable
contributions to the B -> J/psi K decay and estimate soft nonfactorizable
corrections to the a_2 parameter. The corrections appear to be positive,
favoring the positive sign of a_2, in agreement with recent theoretical
considerations and experimental data. Our result also confirms expectations
that in the color-suppressed decay nonfactorizable corrections are sizable.
