The leading non-perturbative QCD corrections to the one-gluon exchange quark-quark, quarkantiquark and qt7 pair-excitation potentials are derived by using a covariant form of non-local two-quark and two-gluon vacuum expectation values. Our numerical calculation indicates that the correction of quark
