The Rolling Stones produced a new four-disc DVD called Four Flicks. TGA Entertainment, the band’s management company, made an agreement with Future Shop (FS) granting FS the exclusive right to sell the DVD set to consumers. In return, the Stones received a larger portion of profits from the DVD than they would have through normal distribution. The music retailer HMV Canada anticipates huge demand for the DVD and wants to be able to sell it through its outlets. TGA refuses to sell to HMV because of the agreement with FS. Is this agreement valid under marketing law? Explain.
