A model is proposed for inclusive $a+b\to c+X$ for $a\overline{c}$ exotic in terms of the Mueller-Regge framework involving $a+b+\overline{c}\to a+b+\overline{c}$ where the central Pomeron—$c$-particle amplitude is approximated by the $c$-particle propagator. In terms of a simple form-factor cutoff parametrization for the $c$-particle propagator, excellent agreement is obtained with the experimental data on inclusive production of $\phi$ and $\psi$. It is argued that even when $a\overline{c}$ is not exotic our model is applicable as long as $t$ and $u$ are large.
