  To include the quark sector, the $A_{5}\equiv I$ (icosahedron) four
generation lepton model is extended to a binary icosahedral symmetry $I'$
flavor model. We find the masses of fermions, including the heavy sectors, can
be accommodated. At leading order the CKM matrix is the identity and the PMNS
matrix, resulting from same set of vacua, corresponds to tribimaximal mixings.
