We apply the method of QCD light-cone sum rules to calculate nonfactorizable contributions to the $\stackrel{\ensuremath{\rightarrow}}{B}J/\ensuremath{\psi}K$ 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.
