A detailed analysis is presented of the Reggeized pion exchange Deck model for processes of the type ap $Yields$ A*N $Yields$ (a*$pi$)N, where a = $pi$, K, or nucleon and a* = rho, K*, or $delta$. Predictions of the model for both production and decay properties of the low mass system A* $Yields$ (a*$pi$) are derived and contrasted with data. Diffractive as well as charge exchange reactions are treated. The role of pion exchange in generating (a*$pi$) enhancements near threshold and their properties is examined from several points of view. Characteristic exchange effects and quantum number properties (e.g., crossovers) of the pion exchange Deck graph are shown to be verified in the data, but this graph alone is inadequate. The failures all point to the need for a second graph, having a* exchange properties. The contribution of a* exchange is roughly equal to that of the $pi$-exchange graph. (auth)
