Using the epsilon expansion of Reggeon field theory, we evaluate the exponent which governs the behavior of the inclusive differential cross section in the triple-Regge region at second order. It is found that the first-order result is modified by contributions coming from g/sup 4/ terms connecting three Pomeron lines, and that only diagrams with one or two Pomeron lines attached to the external particles are important at asymptotic energies.
