We study formal classification of systems of differential equations of the form (1) in the case of function a(α) having two structurally stable critical points. Invariants of such vector fields are constructed in the nonresonant case. Conditions of equivalence of the system to a linear or to an autonomous one are stated in terms of these invariants.
