FOR IMMEDIATE RELEASE
 
FORT WORTH, TEXAS
JUNE 15, 1998
 
                         CRESCENT REAL ESTATE EQUITIES
                      ANNOUNCES THAT 66% DIVIDEND INCREASE
                     WILL FOLLOW CLOSING OF STATION MERGER
 
     Crescent Real Estate Equities Company (NYSE:CEI), one of the country's
largest real estate investment trusts, today announced that the board of trust
managers has approved, upon completion of its pending merger with Station
Casinos, Inc. (NYSE:STN), an increase in the company's quarterly dividend to
$.63 per share from $.38 per share, representing an increase of approximately
66%. Crescent anticipates completion of the merger in the fourth quarter of
1998, subject to approval by Station's shareholders, gaming regulators in Nevada
and Missouri and satisfaction of other closing conditions.
 
     Gerald W. Haddock, Crescent's president and chief executive officer
commented, "In determining the new dividend amount, management and the board of
trust managers considered such factors as the Company's substantial cash flow
growth in the prior twelve months and near-term and long-term internal and
external growth prospects, including the accretion resulting from the Station
transaction. After initiating this dividend increase upon completion of the
Station merger, the Company will continue to maintain a conservative payout
ratio based on both funds from operations and funds available for distribution."
 
     Crescent also announced that, upon completion of the merger with Station,
it will commence a rights offering, pursuant to which Crescent's shareholders
(including the former shareholders of Station) will receive one right for each
share of common stock held. Every five rights will entitle the holder thereof to
purchase one share of Crescent common stock at an exercise price of $31 1/8 per
share, which was the closing price of the common stock on June 12, 1998, as
reported by the NYSE. Unitholders in Crescent's operating partnership will
receive corresponding rights. All of the rights will be exercisable until 60
days after the record date for the distribution. The record date for
distribution of the rights will follow the closing of the merger with Station.
Proceeds of the rights offering will be used to fund acquisitions or to prepay
outstanding borrowings. The rights offering will be made pursuant to a
registration statement filed today with the Securities and Exchange Commission,
following its effectiveness.
 
     Crescent also announced that it intends to contribute substantially all of
the real estate assets acquired from Station to a new partnership (the "Casino
Partnership") that will invest principally in casinos, other gaming properties
and other real estate properties in Las Vegas, Nevada. Crescent initially would
own all of the Casino Partnership, but expects to offer Crescent's shareholders
and unitholders rights to acquire common or preferred equity interests in the
Casino Partnership, or in a real estate investment trust which would hold
interests in the Casino Partnership. The record date for any such offering will
follow the closing of the merger with Station. Any proceeds raised through such
an offering would be used to prepay indebtedness assumed in connection with the
Station merger or to fund new acquisitions or developments. No decisions have
been made as to the terms of any such offering, or as to what securities might
be offered. The structuring of the Casino Partnership has not been finalized,
and its formation is contingent upon the closing of the merger transaction with
Station.
 
     "A rights offering currently represents the optimal manner in which to
raise new equity as it provides our shareholders the ability to maintain their
pro rata ownership interests in Crescent," stated Mr. Haddock. "Furthermore,
because of the opportunity we have to expand the Station gaming franchise, a
separately capitalized and focused gaming entity in which Crescent retains
control and the majority of the ownership is the ideal structure to execute our
game plan."

     Crescent will be conducting a conference call to discuss these
announcements on Monday, June 15, 1998 at 4:00 P.M. EST. To access the
conference call, please dial 800/779-1743 (Code: Crescent).
 
     Crescent is a fully integrated real estate company which, upon completion
of certain pending transactions, will own through its subsidiaries a portfolio
of real estate assets, consisting of 88 office properties and 7 retail
properties totaling 32 million square feet, a 38% interest in 94 refrigerated
warehouse facilities, 89 behavioral healthcare facilities, 6 hotel/casino
properties, 7 full-service hotels totaling 2,276 rooms, 2 destination health and
fitness resorts, and economic interests in 5 residential development

TERMS OF DECLARATION OF STOCK PURCHASE RIGHTS

   Crescent common stock for $31 1/8. The same number of unit purchase rights
   will entitle a holder to purchase one unit of Crescent Real Estate Equities
   Limited Partnership for $66 1/4.
 
4. The rights will be freely transferable and will be listed for trading on the
   New York Stock Exchange.
 
5. The record date for the distribution of rights shall be established by the
   board of directors of Crescent, in its discretion, so long as the record date
   follows the Effective Time of the Merger.
