Boards of Directors have approved in principle MGM Grand`s acquisition of
Primadonna in an all stock transaction.  The terms of the merger provide for
Primadonna`s stockholders to receive 0.33 shares of MGM Grand common stock for
each share of Primadonna stock held, or a total of approximately 9.5 million
shares of MGM Grand common stock.  The transaction is subject to the execution
of a definitive merger agreement, Primadonna shareholder approval and the
satisfaction of various conditions to be contained in the merger agreement,
including obtaining certain regulatory approvals.

The parties expect to enter into a definitive merger agreement within two
weeks.  The merger is expected to be completed in the first quarter of 1999.
 
Primadonna`s assets include three hotel/casino resorts in Primm, Nevada,
50% ownership of New York - New York Hotel and Casino in Las Vegas, Nevada,
and two world class golf courses.  The Primm, Nevada hotel/casino resorts and
golf courses are located on approximately 590 acres of company-owned land in
California and Nevada, of which about 140 acres are undeveloped.  In addition,
the company leases 142 acres of land in Nevada.

“The combination of Primadonna and MGM Grand affords us the opportunity to
take advantage of economies of scale, as well as the diversification of
revenues,” said J. Terrence Lanni, MGM Grand`s Chairman and Chief Executive
Officer.

“This is a significant step toward our goal of creating a gaming and
entertainment giant,” said Alex Yemenidjian, MGM Grand`s President and Chief
Operating Officer.

“We believe that the merger is compelling for Primadonna`s shareholders.
By joining with MGM Grand, Primadonna`s shareholders will benefit from MGM
Grand`s financial strength and exciting growth prospects.  The exchange
represents a premium for Primadonna, based on stock prices for Primadonna and
MGM Grand when negotiations commenced,” said Gary E. Primm, Primadonna`s
Chairman and Chief Executive Officer.

“We believe MGM Grand will continue to enjoy the strongest balance sheet
in the gaming industry after the merger.  The transaction will be accounted
for as a purchase, and the acquisition will be immediately accretive to MGM
Grand`s earnings, even before taking into effect anticipated cost savings and
synergies,” said James J. Murren, MGM Grand`s Chief Financial Officer.

Morgan Stanley Dean Witter is advising Primadonna on this transaction.
