Hadronic corrections to the annihilation rate of heavy vector mesons to lepton pairs are considered to leading nontrivial order in gluon exchange and in the quark-confining potential. It is shown that, to an excellent approximation, the rate is GAMMA (V ..-->.. l/sup +/l/sup -/) approx. = (16..pi cap alpha../sup 2/e/sub Q/ /sup 2//M/sup 2/) vertical-barphi/sub 0/(r = 1/m) vertical-bar/sup 2/, where M approx. = 2m is the vector-meson mass and phi/sub 0/(r) is the solution of the zeroth-order nonrelativistic quark-antiquark bound-state problem. This has the effect of reducing the Van Royen--Weisskopf prediction for the rate.
