  The next generation of electron-hadron facilities has the potential for
significantly improving our understanding of exotic hadrons. The XYZ states
have not been seen in photon-induced reactions so far. Their observation in
such processes would provide an independent confirmation of their existence and
offer new insights into their internal structure. Based on the known
experimental data and the well-established quarkonium and Regge phenomenology,
we give estimates for the exclusive cross sections of several XYZ states. For
energies near threshold we expect cross sections of few nanobarns for the
Zc(3900)+ and upwards of tens of nanobarn for the X(3872), which are well
within reach of new facilities.
