Nucleon-exchange effects are examined in the case where one of the nuclei involved exhibits properties of considerable clustering. The results, obtained by analyzing the exponential parts of the exchange-normalization kernel function in a three-cluster resonating-group formulation, indicate that, as in the case of no target clustering, the one-exchange and core-exchange terms are still the terms which make the dominant contribution. The characteristics of the one-exchange term are found to be rather insensitive to the clustering nature of the target nucleus. The core-exchange term, on the other hand, may acquire a rather long range compared to the direct potential when the degree of clustering is appreciable.
