On the basis of the operator-formulation of the conventional dual resonance model we derive an expression for the one-loop Pomeron exchange amplitude with four external excited particles lying on the parent Regge trajectory. Evaluation of the high energy behaviour leads to the definition of spin-spin-Pomeron form factors. There is a leading Pomeron contribution only if the sum of external spins is even. The dual Pomeron does not exhibit any helicity conservation properties except for <I>s</I>-channel forward scattering. The extension to multiloop amplitudes is briefly discussed.
