  An analogue of the Oppenheimer-Synder collapsing model is treated
analytically, where the matter source is a scalar field with an exponential
potential. An exact solution is derived followed by matching to a suitable
exterior geometry, and an analysis of the visibility of the singularity. In
some situations, the collapse indeed leads to a finite time curvature
singularity, which is always hidden from the exterior by an apparent horizon.
