Let ℙ=()>0 be a 0-contraction semigroup on a real Banach space ℬ. A ℙ-exit law is a ℬ-valued function ∈]0,∞[→∈ℬ satisfying the functional equation: =+, ,>0. Let be a Bochner subordinator and let ℙ be the subordinated semigroup of ℙ (in the Bochner sense) by means of . Under some regularity assumption, it is proved in this paper that each ℙ-exit law is subordinated to a unique ℙ-exit law
