We present a new method for making exact calculations of physical quantities of two-dimensional gauge-fermion models on a finite lattice. The method is applied to the {ital Z}{sub 2} gauge-fermion model with a Kogut-Susskind fermion action. The behavior of the zeros of the partition function, Wilson loops, and other quantities is explicitly examined on the basis of the exact calculation on a 6{times}4 lattice. A novel symmetry of the partition function and the Wilson loop is also discussed briefly.
