A nonsingular cosmological scenario based on a new phenomenological decay law for the effective term is proposed. In such a model, the cosmic history began from an instability of the de Sitter space-time rather than a singularity. The process is characterized by an arbitrary time scale H₈^-1 giving the largest value of the cosmological constant (₈=3H₈^2) and the initial temperature of the Universe. Subsequently, the Universe evolved continuously toward a slightly modified Friedmann-Robertson-Walker cosmology. Among the "remnants" of the primordial inflationary period are the present values of the cosmological term ₀3H₀^2, the density parameter ₀1-, and the deceleration parameter q₀ (1-3) 2, where is smaller than unity. In addition, the age parameter of the vacuum-matter-dominated phase is H₀t₀23 (1-). It is also shown that, if H₈^-1 is of the order of the Planck time, the Universe started with the Planck temperature and this model is consistent with the theoretically suggested value {₁}{₀10^118}.
