  The exponential parameterization of Pontecorvo-Maki-Nakagawa-Sakata mixing
matrix for neutrino is discussed. The exponential form allows easy
factorization and separate analysis of the CP-violating and Majorana terms.
Based upon the recent experimental data on the neutrino mixing, the values for
the exponential parameterization matrix for neutrinos are determined. The
matrix entries for the pure rotational part in charge of the mixing without
CP-violation are derived. The complementarity hypothesis for quarks and
neutrinos is demonstrated. The comparison of the results, based on most recent
and on old data is held. The CP-violating parameter value is estimated, based
on the so far imprecise experimental indications, regarding CP-violation for
neutrinos. The unitarity of the exponential parameterisation and the
CP-violating term transform is confirmed. The transform of the neutrino mass
state vector by the exponential matrix with account for CP-violation is shown.
