             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 



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 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 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.
