The refined infinite-momentum limit approach is used in the derivation amplitudes. The sum rules are based on covariance, causality, and fixed-q$sup 2$ unsubtracted dispersion relations in $nu$ for the amplitudes. The fixed-mass sum rules so obtained are found to include those of the light-cone algebra. For amplitudes where the unsubtracted dispersion relation assumption is doubtful, the results are shown to be unaltered if once-subtracted dispersion relations are assumed instead. Convergence of the sum rules and inclusion of class-II contributions are also discussed. (AIP)
