Ferromagnetic ordering in a generalization of the Hubbard model with correlated hopping to the case of twofold orbital degeneracy has been studied. An effective Hamiltonian of the model has been derived for the case of strong intra-atomic Coulomb repulsion and strong Hund's rule coupling. The energy
