Abstract
The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric particles, with masses less than M/sub Z/. These particles might also provide decay channels for the fourth generation quarks of mass ~100 GeV. We also require tan beta to lie in the range 1.50 lt or approximately=tan beta 1.75 and obtain an upper limit on the lightest Higgs boson mass in the MSSM4 of 152 GeV.
