  Recent improvements of the hard scattering picture for exclusive reactions,
namely the inclusion of both Sudakov corrections and the intrinsic transverse
momentum dependence of the hadronic wave function, are reviewed. On account of
these improvements the perturbative contribution to the pion's form factor can
be calculated in a theoretically self-consistent way for momentum transfers as
low about $2\,{\rm GeV}$. This is achieved at the expense of a substantial
suppression of the perturbative contribution in the few GeV region. Eventual
higher twist contributions are also discussed.\\
