We find broad classes of exact 4-dimensional asymptotically flat black holesolutions in Einstein-Maxwell theories with a non-minimally coupled dilaton andits non-trivial potential. We consider a few interesting limits, in particular,a regular generalization of the dilatonic Reissner-Nordstr{\"o}m solution and,also, smooth deformations of supersymmetric black holes. Further examples areprovided for more general dilaton potentials. We discuss the thermodynamicalproperties and show that the first law is satisfied. In the non-extremal casethe entropy depends, as expected, on the asymptotic value of the dilaton. Inthe extremal limit, the entropy is determined purely in terms of charges and isindependent of the asymptotic value of the dilaton. The attractor mechanism canbe used as a criterion for the existence of the regular solutions. Since thereis a `competition' between the effective potential and dilaton potential, wealso obtain regular extremal black hole solutions with just one U(1) gaugefield turned on.
