We suggest new benchmark scenarios for the Higgs-boson search at LEP2. Keeping mt and MSUSY fixed, we improve on the definition of the maximal mixing benchmark scenario defining precisely the values of all MSSM parameters such that the new mhmax benchmark scenario yields the parameters which maximize the value of mh for a given tan(beta). The corresponding scenario with vanishing mixing in the scalar top sector is also considered. We propose a further benchmark scenario with a relatively large value of |mu|, a moderate value of MSUSY, and moderate mixing parameters in the scalar top sector. While the latter scenario yields mh values that in principle allow to access the complete MA-tan(beta)-plane at LEP2, on the other hand it contains parameter regions where the Higgs-boson detection can be difficult, because of a suppression of the branching ratio of its decay into bottom quarks.
