Gompf's end-sum techniques are used to establish the existence of an infinity of non-diffeomorphic manifolds, all having the same trivial R^4 topology, but for which the exotic differentiable structure is confined to a region which is spatially limited. Thus, the smoothness is standard outside of a region which is topologically (but not smoothly) B^3× R^1, where B^3 is the compact three ball. The exterior of this region is diffeomorphic to standard R^1× S^2× R^1. In a space-time diagram, the
