Abstract: The symplectization of an overtwisted contact $(\mathbb {R}^3,\xi _{ot})$ is shown to be an exotic symplectic $\mathbb {R}^4$. The technique of proof is also used to produce exotic symplectic $\mathbb {R}^{2n}$ using a GPS–structure and applies to symplectizations of open contact manifolds.
