We examine the LEP limits for the Zh{yields}Z+b's final state and find that the excess of observed events for m{sub h}{approx}100 GeV correlates well with there being an m{sub h}{approx}100 GeV Higgs boson with SM-like ZZh coupling that decays partly via h{yields}bb+{tau}{sup +}{tau}{sup -} [with B(h{yields}bb){approx}0.08] but dominantly via h{yields}aa [with B(h{yields}aa){approx}0.9], where m{sub a}<2m{sub b} so that a{yields}{tau}{sup +}{tau}{sup -} (or light quarks and gluons) decays are dominant. This type of scenario is precisely that predicted in the Next-to-Minimal Supersymmetric Model for parameter choices yielding the lowest possible fine-tuning.
