We demand: gauge coupling constant unification at high energy scales; perturbative values for all Yukawa couplings for energy scales $\\leq \\mgut$; radiative electroweak symmetry breaking via renormalization group evolution; and a neutral LSP. The perturbative constraints imply a light fourth-family quark and lepton spectrum, and $\\tanb\\lsim 3$. The lightest CP-even Higgs mass is increased.
