The qqq-barq-bar system has been examined by solving the four-particle Schroedinger equation variationally. The main findings are that: (1) qqq-barq-bar bound states normally do not exist, (2) the cryptoexotic 0/sup + +/ sector of this system with KK-bar quantum numbers is probably the only exception to (1) and its bound states can be identified with the S* and delta just below KK-bar threshold, (3) qqq-barq-bar bound states provide a model for the weak binding and color-singlet clustering observed in nuclei, and (4) there is no indication that this system has strong resonances.
