In CDF we have observed exclusive processes gamma gamma
--> e+ e- and mu+ mu-, gamma + IP --> J/psi, psi(2S) and IP + IP
--> chi(c).  The cross sections agree with QED, HERA photoproduction
data, and theoretical estimates of gg --> chi(c) with another gluon
exchanged to screen the color.  This observation of exclusive chi(c),
together with earlier observations of exclusive dijets and exclusive
gamma gamma candidates, support some theoretical predictions for p +
p --> p + SMH + p at the LHC.  Exclusive dileptons offer the best
means of precisely calibrating forward proton spectrometers.
