The kinetic exchange mechanism in Anderson's theory of super-exchange is formulated for the case of Co^<2+> in CoO. The exchange interaction depends on the orbital augular-momentum operators as well as on the spin operators. The nearest neighbor interaction is shown to be largely anisotropic. The coeffcients of the exchange interaction are estimated with the following parameters: Mattheiss'APW result and its modification for the transfer integrals, Anderson's value for the effective Coulomb integral, and the experimental values for the intra-ionic exchange integral and the crystalline field splitting. The estimated values should be correct at least in order of magnitude on account of the fact that the came procedure in the cases of NiO and MnO give result in fairly good agreement with the experimental result. The potential exchange in CoO is also discussed.
