In this paper we show that uniformly global asymptotic stability for a family of ordinary differential
equations is equivalent to uniformly global exponential stability under a suitable nonlinear change of
variables. The same is shown for input-to-state stability and input-to-state exponential stability, and for
input-to-state exponential stability and a nonlinear $H_\infty$ estimate.

Keywords: asymptotic stability, exponential stability, input-to-state stability, state transformation
