The LEP-II bound on the light Higgs mass rules out the vast majority ofparameter space left to the Minimal Supersymmetric Standard Model (MSSM) withweak-scale soft-masses. This suggests the importance of exploring extensions ofthe MSSM with non-minimal Higgs physics. In this article, we explore a theorywith an additional singlet superfield and an extended gauge sector. The theoryhas a number of novel features compared to both the MSSM and Next-to-MSSM,including easily realizing a light CP-even Higgs mass consistent with LEP-IIlimits, tan(beta) < 1, and a lightest Higgs which is charged. These featuresare achieved while remaining consistent with perturbative unification andwithout large stop-masses. Discovery modes at the Tevatron and LHC arediscussed.Comment: 15 pages, 5 figures; Typo in equation (4.5) corrected; submitted to JHE
