  We study the effects of dimension six terms on the predictions of the
holographic model for the vector meson form factors and determine the
corrections to the electric radius, the magnetic and the quadrupole moments of
the rho-meson. We show that the only dimension six terms which contribute
nontrivially to the vector meson form factors are X^2F^2 and F^3. It appears
that the effect from the former term is equivalent to the metric deformation
and can change only masses, decay constants and charge radii of vector mesons,
leaving the magnetic and the quadrupole moments intact. The latter term gives
different contributions to the three form factors of the vector meson and
changes the values of the magnetic and the quadrupole moments. The results
suggest that the addition of the higher dimension terms improves the
holographic model.
