We address the mu problem of gauge mediation by considering a singlet chiral superfield coupled to the Higgs and messenger fields. We compute the soft terms generated below the messenger scale and study the phenomenological consequences of the model. The experimental bound on the Higgs mass provides a severe constraint that identifies three special regions of parameters where the mass spectrum and the collider signatures can be distinct from ordinary gauge mediation.
