Abstract: We consider the realization of four-dimensional theories with $N=2$ supersymmetry as $M$-theory configurations including a five-brane. Our emphasis is on the spectrum of massive states that are realized as two-branes ending on the five-brane. We start with a determination of the supersymmetries that are left unbroken by the background metric and five-brane. We then show how the central charge of the $N=2$ algebra arises from the central charge associated with the $M$-theory two-brane. This determines the condition for a two-brane configuration to be BPS saturated in the four-dimensional sense. By imposing certain conditions on the moduli, we can give concrete examples of such two-branes. This leads us to conjecture that vector multiplet and hypermultiplet BPS-saturated states correspond to two-branes with the topology of a cylinder and a disk, respectively.
