Final answer:
An artist may work on a nonexclusive basis with an agency within specific territories or types of performances, retaining the freedom to engage with multiple representatives.
Step-by-step explanation:
An artist may indeed work on a nonexclusive basis with an agency. Such arrangements could be designed within a specific territory or for a particular type of performance. This is a common practice in the arts industry where artists retain the freedom to work with multiple agencies or take on projects outside the agency’s purview, as long as those projects do not directly conflict with the agency's efforts.
Exclusive dealing agreements in other industries, such as between a manufacturer and a dealer, can be either legal or illegal. If the agreement promotes competition among dealers, such as in the case of automotive companies like Ford Motor Company or General Motors selling only to their respective dealers, it is typically legal.
