A microscopic estimate of imaginary coupling potentials used in coupled-channels calculations is performed for the ^6Li+^<40>Ca and ^6Li+^<208>Pb system in the framework of the Feshbach formalism. Two-step contributions to the imaginary potentials are calculated by taking account of the excitation of the target collective states in the intermediate states. The estimated strength of the potential is found to be too small by a factor of about 3 in comparison with the phenomenological one used in the microscopic coupled-channels analyses of ^6Li scattering data by Sakuragi et al.
