  Experiment 865 at the Brookhaven AGS obtained 410 K+ -> e+ nu e+e- and 2679
K+ -> mu+ nu e+e- events including 10% and 19% background. The branching ratios
were measured to be (2.48+-0.14(stat.)+-0.14(syst.))x10^-8 (m_ee>150 MeV) and
(7.06+-0.16+-0.26)x10^-8 (m_ee>145 MeV), respectively. Results for the decay
form factors are presented.
