Abstract
We consider static solutions of two dimensional dilaton gravity models as toy laboratories to address the question of the final fate of black holes. A non perturbative correction to the CGHS potential term is shown to lead classically to an extremal black hole geometry, thus providing a plausible solution to Hawking evaporation paradox. However, the full quantum theory does not admit an extremal solution.

12 pages, LaTex, no figures. We have improved the main argument leading to the non-existence of an extremal black hole in the quantum theory
