We show that any element of the special linear group SL₂(R) is a product of two exponentials if the ring R is either the ring of holomorphic functions on an open Riemann surface or the disc algebra. This is sharp: one exponential factor is not enough since the exponential map corresponding to SL₂(C) is not surjective. Our result extends to the linear group GL₂(R), where it is sharp as well.
