BRG of Georgia, Inc. (BRG), and Harcourt Brace Jovanovich Legal and Professional Publications (HJB) are the nation's two largest providers of bar review materials and lectures. HJB began offering a Georgia bar review course on a limited basis in 1976 and was in direct, and often intense, competition with BRG from 1977 to 1979 when the companies were the two main providers of bar review courses in Georgia. In early 1980, they entered into an agreement that gave BRG an exclusive license to market HJB's materials in Georgia and to use its trade name "Bar/Bri." The parties agreed that HJB would not compete with BRG in Georgia and that BRG would not compete with HJB outside of Georgia. Under the agreement, HJB received $100 per student enrolled by BRG and 40 percent of all revenues over $350. Immediately after the 1980 agreement, the price of BRG's course was increased from $150 to more than $400. Is their conduct illegal under federal antitrust laws? [Palmer v.
