  We discuss exclusive production of lepton-antilepton, quark-antiquark, $\pi
\pi$ and $\rho^0 \rho^0$ pairs in ultraperipheral, ultrarelativistic heavy-ion
collisions.
  The cross sections for exclusive production of pairs of particles is
calculated in Equivalent Photon Approximation (EPA). Realistic (Fourier
transform of charge density) charge form factors of nuclei are used and the
corresponding results are compared with the cross sections calculated with
monopole form factor used in the literature. Absorption effects are discussed
and quantified. The cross sections obtained with realistic form factors are
significantly smaller than those obtained with the monopole form factors.
