We present an evaluation of a two-photon exchange correction to the cross section for unpolarized Ξ” isobar production in electron-proton collisions, using a relativistic, crossing symmetric and gauge invariant approach. The calculated box and crossed-box diagrams include nucleon and Ξ” intermediate s
