We show that the Random Energy Model has interesting rejuvenation properties in its frozen phase. Different "susceptibilities" to temperature changes, for the free energy and for other ("magnetic" ) observables, can be computed exactly. These susceptibilities diverge at the transition temperature, as for the free energy.
