Results from studies on exclusive production of electron-p=
osition pair, di-photon, and di-jet production at CDF in proton-antip=
roton collisions at the Fermilab Tevatron are presented.  The first o=
bservation and cross section measurements of exclusive e+ e- and di=
-jet production in hadron-hadron collisions are emphasized.
