Pinnacle Entertainment Closes Sale of Remaining 60 Acres of Land in Inglewood, California for $36 Million

Pinnacle Entertainment, Inc. today announced that it completed the previously disclosed pending sale of the remaining 60 acres of land in Inglewood, California. The Company received approximately $33 million on May 28, 2004, which constitutes the balance of the $36 million total purchase price. Previously the Company had received $3 million of non-refundable deposits. After expenses, the Company anticipates net cash proceeds of approximately $35 million and a gain of approximately $28 million when further reduced for the net book value of the land and other costs. Consistent with the previously announced 37-acre land sale in February, the Company does not anticipate paying any current income tax on this land sale based on its federal net operating loss carry-forwards.

The Company intends to use the net cash proceeds to fund its development plans, including the Lake Charles project, the downtown St. Louis project and the St. Louis County project (in the case of each St. Louis project, pending approval by the Missouri Gaming Commission).

Pursuant to the Company’s bank agreement, its approximate $68 million delayed draw term loan commitment will be reduced by 50% of the net cash proceeds from the land sale. Hence, the delayed draw term loan will be reduced to approximately $50 million. The Company’s $75 million revolver remains undrawn and available.
