A complete classification is given for quasi-symmetric design which have intersection numbers 0 and 2 and which satisfy certain conditions concerning sub-configurations. It is also proved that if a biplane B(k) has characteristic 3 then k is divisible by 3 and the number of points of the biplane is even.
