  We present 15 binary lens candidates from OGLE-III Early Warning System
database for seasons 2002-2003. We also found 15 events interpreted as single
mass lensing of double sources. The candidates were selected by visual light
curves inspection. Examining the models of binary lenses of this and our
previous study (10 caustic crossing events of OGLE-II seasons 1997-1999) we
find one case of extreme mass ratio binary (q ~ 0.005) and the rest in the
range 0.1<q<1.0, which may indicate the division between planetary systems and
binary stars. There is no strong discrepancy between the expected and the
observed distributions of mass ratios and separations for binary stars.
