  In this talk we discuss an $E_6$ inspired supersymmetric (SUSY) model with an
extra $U(1)_{N}$ gauge symmetry under which right-handed neutrinos have zero
charge. In this exceptional supersymmetric standard model (E$_6$SSM) the
$\mu$-term is generated dynamically after the electroweak symmetry breaking. We
specify the particle content of the model and argue that the presence of a $Z'$
and exotic particles predicted by E$_6$SSM allows the lightest Higgs boson to
be significantly heavier than in the MSSM and NMSSM. Other possible
manifestations of E$_6$SSM at the LHC are also discussed.
