  We present new results on the related rare KL decay modes KL -> pi+ pi- gamma
and KL -> pi+ pi- e+ e-. KTeV has performed the first direct measurement of the
form factor for the "direct emission" component of KL -> pi+ pi- gamma decays,
a quantity with ramifications for particular chiral models. In addition, the
form factor and direct emission/inner bremsstrahlung branching ratio - also
presented here - are important input parameters for the understanding of the
planar-angle distribution of KL -> pi+ pi- e+ e- decays. Preliminary results
indicating the presence of a T-violating asymmetry in the KL -> pi+ pi- e+ e-
angular distribution are presented.
