               DOUBLETREE CORPORATION AND PROMUS HOTEL CORPORATION
                  SIGN $4.7 BILLION DEFINITIVE MERGER AGREEMENT

         PHOENIX, AZ AND MEMPHIS, TN, SEPTEMBER 2, 1997 - Doubletree Corporation
(NASDAQ: TREE) and Promus Hotel Corporation (NYSE: PRH) today announced the
execution of a definitive merger agreement, creating one of the world's largest
hotel companies with a portfolio of fast-growing upscale and mid-priced brands
including Doubletree Hotels, Embassy Suites, Doubletree Guest Suites, Homewood
Suites, Club Hotels by Doubletree, Hampton Inn, Hampton Inn & Suites, and Red
Lion. This stock-for-stock transaction, valued at approximately $4.7 billion, is
a merger of equals, combining Doubletree's strength in hotel management with
Promus' strength in franchising and building brands.

         With approximately $5 billion in annual system-wide revenues under
management contract for franchise agreement, the combined company will be the
lodging industry's third largest revenue producer. As of June 30, the new
company had 1,136 hotels, approximately 172,000 rooms, and more than 40,000
employees in all regions of the United States and its major markets, as well as
selected locations in Latin America and Asia.

         The terms of the agreement call for the two companies to be merged into
subsidiaries of a new holding company to be named Promus Hotel Corporation.
Doubletree shareholders will receive one share in the new company for each of
their shares in Doubletree. Promus shareholders will receive 0.925 shares in the
new company for each of their shares in Promus. The transaction is intended to
be accounted for as a pooling-of-interests and is expected to be tax-free. The
merger is













   2



expected to be accretive to earnings per share in the first full year, excluding
costs related to the transaction. The shares of the new company are expected to
be listed on the New York Stock Exchange.

         The companies have agreed that:

         -        Promus' President and Chief Executive Officer, Raymond E.
                  Schultz, will serve as Chairman and Chief Executive Officer of
                  the new company, and as a member of the Board's Executive
                  Committee.

         -        Doubletree's President and Chief Executive Officer, Richard M.
                  Kelleher, will serve as President and Chief Operating Officer
                  following the merger, and will succeed Mr. Schultz as Chief
                  Executive Officer upon his retirement. He will also be an
                  ex-officio member of the Board's Executive Committee.

         -        The key management team will consist of top managers of both
                  Doubletree and Promus, including William L. Perocchi,
                  currently Executive Vice President and Chief Financial Officer
                  of Doubletree, as Executive Vice President and Chief Financial
                  Officer, and Thomas L. Keltner, currently Executive Vice
                  President and Chief Development Officer of Promus, as
                  Executive Vice President and Chief Development Officer.

         -        The new company will be governed by a 14-member Board of
                  Directors, with seven directors designated by each company.
                  The Board will include Richard J. Ferris and Peter V.
                  Ueberroth, Doubletree Co-Chairmen, and Michael D. Rose, Promus
                  Chairman, who will serve as members of the Board's Executive
                  Committee.

         -        Each company has granted the other an option to acquire 19.9
                  percent of its common stock under certain conditions.

         Doubletree also announced that it has adopted a Stockholder Rights
Plan, the details of which will be released separately.

         Approximately 40% of Doubletree's shareholders, including, among
others, General Electric Pension Trust and Kohlberg Kravis Roberts & Co., have
indicated they intend to vote in








   3

favor of the merger. GE and KKR will continue to be represented on the Board of
the new company.

         Raymond E. Schultz, Promus President and Chief Executive Officer, said:
"This transaction is truly a merger of equals. The combined company will greatly
benefit from the complementary strengths of each partner. Doubletree has grown
rapidly through acquisitions and an aggressive conversion strategy. It has an
outstanding record and reputation as a quality operator and brand marketer of
full service hotels. Promus has grown through franchising and new hotel
development. We have grown our proprietary brands primarily on a one-at-a-time
basis with emphasis on product quality and consistency and our unique 100%
satisfaction guaranteed service culture, which will be extended to all
Doubletree's brands."

         Mr. Schultz added, "This merger is a `defining moment' for Promus. We
have achieved a significant presence in the upscale suites and extended-stay
markets, and are the industry leader in the mid-priced limited service segment.
In joining with a quality upscale full-service brand in Doubletree Hotels, as
well as its other brands, the combined company will be able to offer a full
range of quality accommodations to meet the needs of business and leisure
travelers in markets throughout the United States. Our ability to cross-sell and
cross-market our brands will be a key driver of our future growth. We will also
be able to offer to franchisees, developers and investors an even more complete
line of hotel development opportunities in virtually every important segment of
the lodging business.

         "The combination of two of the strongest and most successful management
teams in our industry will provide the depth to continue to grow rapidly and
expand to new areas. Rick Kelleher and I worked together for many years, so I
know we share the same values and commitment to product quality, customer
service and creating shareholder value. The cultures of our companies are
remarkably similar and that should make the transition more seamless. We will
immediately form transition task forces so that we will hit the ground running,"
Mr. Schultz continued.

         Richard M. Kelleher, President and Chief Executive Officer of
Doubletree Corporation, said, "The merger of Doubletree and Promus is a natural
marriage of two strong institutions with a common heritage and a focus on
growth. Doubletree traces its roots to a company that was one of





   4

the original franchisees of Embassy Suites. Today, Embassy Suites is the clear
market leader in the upscale all-suites segment and accounts for more than half
of Promus' operating profit. The blending of Embassy Suites and Doubletree Guest
Suites will give the new company an even stronger base on which to build market
share."

         "There are also tremendous opportunities for growth in the
extended-stay market, with the upscale Homewood Suites brand complementing
Doubletree's investment in the mid-market Candlewood Hotels brand. Likewise, our
smaller Club Hotels by Doubletree and Red Lion brands will benefit from Promus'
strength as a franchisor and builder of brands. We are also excited about having
Hampton Inn, one of this decade's fastest growing mid-market brands, included in
our combined portfolio."

         Mr. Kelleher added, "At a time when the lodging industry is rapidly
consolidating, the merger creates a company with significant free cash flow, one
of the strongest balance sheets in our industry and access to sources of
lower-cost capital than most of our competitors. We are very well positioned to
leverage these financial strengths to accelerate our growth in the future.

         Both companies expect to realize substantial synergies and cost savings
from the merger. They will be able to combine their respective reservation
systems, information system development and maintenance, purchasing functions,
accounting, payroll, and many other corporate support functions to provide
substantial efficiencies. The companies said that their preliminary estimated
cost savings and synergies should yield approximately $15 to $20 million
annually. Both companies have preferred vendor programs which provide growing
revenue streams that will benefit from the combined larger room count.

         Consummation of this transaction is subject to customary conditions,
including regulatory approvals and approval of the merger by shareholders of
each company. It is anticipated that this transaction will close prior to 1997
year-end.
