  A model for Pomeron-Pomeron total cross section in the resonance region
$\sqrt{M^{2}} \le$ 5 GeV is presented. This model is based on Regge poles from
the Pomeron and two different $f$ trajectories, and includes the isolated
f$_{0}(500)$ resonance in the region $\sqrt{M^{2}}\lesssim 1$ GeV. A slowly
varying background is included. The presented Pomeron-Pomeron cross section is
not directly measurable, but is an essential ingredient for calculating
exclusive resonance production at the LHC.
