We consider approaches to the eikonal-like unitarization of elastic amplitude and its generalizations in theories where cross-sections grow with energy, and we discuss corresponding mechanisms of the multiple exchange standing behind it. In particular, we argue that in such theories the weight of the n-fold exchanges can grow with n much faster than for the simplest Glauber eikonal.
