We present a solution of the bootstrap equations in the five--vertex approximation. We show that the bootstrap approach gives a particularly simple way to obtain next to leading order corrections to critical exponents in the large $N$ expansion and present the values of the anomalous dimensions of the fermion field $ψ$ and the composite $\barψψ$ to order $1/N^2$.10pp, text and figures both in latex, UBCTP-92-34High Energy Physics - TheoryCondensed Mattertext
