The dispersion relation for noninteracting excitons and the influence ofperturbative correction is examined in the case of pentacene structure. Thevalues of exchange integrals are determined by the nonlinear fits to theexperimental dispersion data obtained by inelastic electron scattering in Phys.Rev. Lett. \textbf{98}, 037402 (2007). We obtain theoretical dispersion curvesalong four different directions in the Brillouin zone which possess the sameperiodicity as the experimental data. We also showed that perturbativecorrections are negligible since the exciton gap in dispersion relation is hugein comparison to exchange integrals.
