MOHEGAN TRIBAL GAMING AUTHORITY COMMENCES

TENDER OFFER AND CONSENT SOLICITATION

UNCASVILLE, CONNECTICUT, June 19, 2003 – The Mohegan Tribal Gaming Authority (the “Authority”) announced today that it has commenced a cash tender offer and consent solicitation (the “Offer”) for any and all of its $300,000,000 aggregate principal amount of 8.75% Senior Subordinated Notes due 2009 (the “Notes”).

The Offer is scheduled to expire at 12:00 midnight, New York City time, on Thursday, July 17, 2003, unless extended or earlier terminated (the “Expiration Date”). The consent solicitation will expire at 5:00 p.m., New York City time, on Monday, June 30, 2003 (the “Consent Date”). Holders tendering their Notes will be required to consent to certain proposed amendments to the indenture governing the Notes, which will eliminate substantially all of the restrictive covenants. Holders may not tender their Notes without delivering consent or deliver consents without tendering their Notes.

Holders who validly tender their notes by the Consent Date will receive the total consideration of $1,077.50 per $1,000 principal amount of Notes (if such notes are accepted for purchase). Holders who validly tender their Notes after the Consent Date and prior to the Expiration Date will receive as payment for the Notes $1,047.50 per $1,000 principal amount of Notes (if such notes are accepted for purchase). In either case, Holders who validly tender their Notes also will be paid accrued and unpaid interest up to, but not including, the date of payment for the Notes (if such notes are accepted for purchase).

The Offer is subject to the satisfaction of certain conditions, including the Authority’s receipt of tenders of Notes representing a majority of the principal amount of the Notes outstanding and senior subordinated financing on terms acceptable to the Authority in an amount sufficient to consummate the Offer. The terms of the Offer are described in the Authority’s Offer to Purchase and Consent Solicitation Statement dated June 19, 2003, copies of which may be obtained from Mellon Investor Services LLC.
