The low-lying energy spectra of five quark systems $uudcbar{c}$ (I=1/2, S=0) and $udscbar{c}$ (I=0, S=-1) are investigated with three kinds of schematic interactions: the chromomagnetic interaction, the flavor-spin dependent interaction and the instanton-induced interaction. In all the three models, the lowest five quark state ($uudcbar{c}$ or $udscbar{c}$) has an orbital angular momentum L=0 and the spin-parity $J^{P}=1/2^{-}$; the mass of the lowest $udscbar{c}$ state is heavier than the lowest $uudcbar{c}$ state.
