The perturbation-theory mechanism for the exponentiation of all infrared divergences in the bare skeleton expansion of the color-singlet fermion form factor is exhibited. It is observed that infrared exponentiation is also a property of many infinite subsums of the full bare skeleton expansion. The method employed, based on an observation by Weinberg in the context of QED, avoids complicated combinatoric and group-theoretic arguments, and holds in any covariant gauge.
