  Multiquark systems such as tetraquarks, pentaquarks and hexaquarks states are
studied as di-hadronic molecules in a nonrelativistic model. The masses of
several di-hadronic states using a molecular interaction provided by asymptotic
expression of the confined gluon exchange potential are computed. The exotic
states such as f$_0$ (0.982), f$_2$ (1.565), f$_2$ (1.950), X(3.87), D$_{sJ}$
(2.317, 2.460, 2.632), $\psi$(4.040) etc are identified as the low lying
di-mesonic states, and $\Theta^+$ (1.54) as a $K-N$ molecular state.
