ORGANIZATION	NOTE 1—ORGANIZATION: The Mohegan Tribe of Indians of Connecticut (the “Mohegan Tribe” or the “Tribe”) established the Mohegan Tribal Gaming Authority (the “Authority”) in July 1995 with the exclusive authority to conduct and regulate gaming activities for the Tribe on Tribal lands and the non-exclusive authority to conduct such activities elsewhere. The Tribe is a federally-recognized Indian tribe with an approximately 595-acre reservation situated in Southeastern Connecticut, adjacent to Uncasville, Connecticut. Under the Indian Gaming Regulatory Act of 1988, federally-recognized Indian tribes are permitted to conduct full-scale casino gaming operations on tribal lands, subject to, among other things, the negotiation of a compact with the affected state. The Tribe and the State of Connecticut entered into a compact (the “Mohegan Compact”), which was approved by the United States Secretary of the Interior. The Authority is primarily engaged in the ownership, operation and development of gaming facilities. In October 1996, the Authority opened Mohegan Sun, a gaming and entertainment complex situated on an approximately 185-acre site on the Tribe’s reservation. The Authority is governed by a nine-member Management Board, whose members also comprise the Mohegan Tribal Council, the governing body of the Tribe. Any change in the composition of the Mohegan Tribal Council results in a corresponding change in the Authority’s Management Board.
