To Our Stockholders:

    Accompanying this letter are proxy materials concerning the proposed
acquisition by Hilton of Promus Hotel Corporation. The transaction requires the
approval of Hilton stockholders at a special meeting to be held on November 30,
1999. Promus has scheduled a stockholders meeting the same day and we expect to
complete the merger immediately following the stockholder approvals.

    The entire Hilton board and I believe that the acquisition provides a superb
opportunity to increase the profitability of our company and the value of our
shares by:

    - enhancing Hilton's competitive position;

    - increasing revenues from management and franchising;

    - broadening our portfolio of hotel brands and geographic and brand segment
      diversification; and

    - achieving significant synergies and economies of scale.

    YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE PROPOSED TRANSACTION
AND RECOMMENDS A FAVORABLE VOTE BY STOCKHOLDERS.

    In connection with the proposed acquisition, stockholders will also vote on
proposals to amend the Hilton certificate of incorporation to increase the
authorized number of shares of common stock and to amend the Hilton bylaws to
provide flexibility in determining the number of Hilton directors. YOUR BOARD OF
DIRECTORS HAS ALSO UNANIMOUSLY RECOMMENDED APPROVAL OF THESE IMPORTANT MATTERS.

    Details of the proposed acquisition and related proposals are contained in
the enclosed materials. I urge you to review them carefully. PLEASE BE CERTAIN
THAT YOUR SHARES ARE VOTED AT THE SPECIAL MEETING.

                                          Sincerely yours,

                                                     [LOGO]

Dear Fellow Stockholder:                                        October 21, 1999

    We are pleased to enclose information about a Special Meeting of
Stockholders of Promus Hotel Corporation on November 30, 1999. At the meeting,
you will be asked to approve an Agreement and Plan of Merger dated as of
September 3, 1999, as amended, among Promus, Hilton Hotels Corporation and PRH
Acquisition Corporation.

    The merger agreement provides for Hilton's acquisition of Promus. In the
acquisition, you may elect to receive, for each share of Promus common stock,
either (1) $38.50 in cash or (2) not less than 2.9096 shares or more than 3.2158
shares of Hilton common stock, determined by a formula in the merger agreement.
Your election may be subject to proration to ensure that 55% of the outstanding
Promus shares are converted into cash, while the remaining 45% are converted to
Hilton common stock. Receipt of the Hilton stock may or may not be a taxable
event to you, depending on the circumstances described in the enclosed Joint
Proxy Statement/Prospectus. We urge you to read the Joint Proxy
Statement/Prospectus carefully.

    The acquisition represents an attractive transaction because of the
strategic fit between Promus and Hilton. Promus's own strategic planning process
had identified several strategic needs which the acquisition specifically
addresses, such as the need for: (1) a global brand which could provide
overarching support for market acceptance of our family of brands; (2) a
stronger national sales force and international market access which could draw
group business; (3) a customer loyalty/frequency program which could increase
property-level revenues; (4) further expansion of cross-selling efforts which
could drive revenue growth; and (5) the acquisition or development of
owner/operator time-sharing expertise to complement our strong position in this
market.

    In each case, we believe the combination with Hilton satisfies our strategic
needs, resulting in a compelling strategic fit. Hilton is probably the most
recognized global brand in the industry. Our Doubletree brand will benefit from
the new brand affiliation. Hilton has one of the most effective national sales
forces. Its strategic alliance with Hilton International will also provide
Promus with global market access. Hilton HHonors frequency program is one of the
most recognized and effective in the industry. With a total of approximately
1700 hotels and very large, high quality Hilton hotels in major urban markets
(e.g., Waldorf Astoria in New York City), the opportunity for cross-selling and
regional cost synergies are significant. Hilton is an established owner/operator
of time-sharing resorts which provides expertise to be more successful in this
market. Moreover, our Harrison Conference Centers business will fit nicely with
Hilton's existing conference centers and large-scale hotels.

    This transaction will benefit all of our stakeholders. Our stockholders
benefit from a purchase premium and the opportunity to become stockholders in a
larger, more competitive company with greater profit potential. Our owners and
franchisees will benefit from significant revenue and cost synergies as well as
their involvement with a company which has a broader array of quality brands.
Our guests will benefit from our continued high-quality service, involvement in
the Hilton HHonors program and a broader selection of brands and locations. Our
employees can benefit from being involved with a larger company, which will
offer greater career opportunities.

    MY FELLOW DIRECTORS AND I HAVE UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
RECOMMEND YOU VOTE FOR ITS APPROVAL.

                        JOINT PROXY STATEMENT/PROSPECTUS

    Hilton Hotels Corporation and Promus Hotel Corporation have entered into a
merger agreement that provides for Hilton's acquisition of Promus. In the
acquisition, Promus stockholders will receive, at their election, for each share
of Promus common stock, either:

    - $38.50 in cash; or

    - not less than 2.9096 shares or more than 3.2158 shares of Hilton common
      stock, determined as described below.


    Each Promus stockholder's election may be subject to proration depending on
the form of consideration other Promus stockholders elect to receive. The
proration will ensure that 55% of the outstanding Promus shares will be
converted into cash, while the remaining 45% will be converted into Hilton
common stock.


    Promus stockholders who receive Hilton common stock will receive a number of
shares equal to $38.50 divided by the average Hilton stock price, but in any
event not less than 2.9096 shares or more than 3.2158 shares for each share of
Promus common stock. The average Hilton stock price is the average of the volume
weighted average per share sales price of Hilton common stock on the NYSE for 20
trading days selected by lot from the 30 trading days ending on the fifth
trading day before the closing of the acquisition.

    The acquisition requires the approval of both Promus and Hilton
stockholders.

    Hilton is also asking its stockholders to approve an amendment to Hilton's
certificate of incorporation to increase the authorized number of shares of
Hilton common stock from 400 million shares to 500 million shares. If approved,
the amendment to the certificate of incorporation will take effect only if the
acquisition is completed. Hilton is also asking its stockholders to approve an
amendment to Hilton's by-laws to change the authorized number of directors from
12 to a range of 10 to 20 directors, with the exact number to be set from time
to time by the Hilton board of directors. If approved, the amendment to the
by-laws will take effect regardless of the outcome of the votes on the
acquisition and the amendment to Hilton's certificate of incorporation. APPROVAL
OF THE MERGER AGREEMENT AND COMPLETION OF THE ACQUISITION ARE NOT DEPENDENT ON
APPROVAL OF THE PROPOSED AMENDMENTS TO THE HILTON CERTIFICATE OF INCORPORATION
OR BY-LAWS.

    THE BOARDS OF DIRECTORS OF HILTON AND PROMUS UNANIMOUSLY RECOMMEND THAT YOU
VOTE IN FAVOR OF THE ACQUISITION AND, IN THE CASE OF HILTON, THE OTHER MATTERS.
YOUR VOTE IS VERY IMPORTANT. Whether or not you plan to attend a meeting, please
take the time to vote by completing and mailing the enclosed proxy card to us or
voting by telephone.


    This joint proxy statement/prospectus provides you with detailed information
about the acquisition, a description of which begins on page 32. YOU SHOULD ALSO
CAREFULLY READ THE SECTION ENTITLED "RISK FACTORS" BEGINNING ON PAGE 23 FOR A
DISCUSSION OF SPECIFIC RISKS THAT YOU SHOULD CONSIDER IN DETERMINING HOW TO VOTE
ON THE PROPOSED ACQUISITION.


    NEITHER THE SEC NOR ANY STATE SECURITIES REGULATOR HAS APPROVED THE
SECURITIES TO BE ISSUED UNDER THIS JOINT PROXY STATEMENT/PROSPECTUS OR
DETERMINED IF THIS JOINT PROXY STATEMENT/PROSPECTUS IS ACCURATE OR ADEQUATE. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.


    This joint proxy statement/prospectus is dated October 21, 1999, and is
first being mailed to stockholders of Hilton and Promus on October 25, 1999

       Hilton, Inc., and to approve the acquisition of Promus by Hilton.


       We anticipate that the acquisition will be effected by the merger of
       Promus into PRH Acquisition, with PRH Acquisition being the surviving
       corporation. We call this the forward merger structure. However, we will
       use a reverse merger structure in which PRH Acquisition will merge into
       Promus, with Promus being the surviving corporation and a wholly-owned
       subsidiary of Hilton, if either of the following occurs:

       - the value of the Hilton stock delivered in the acquisition is less than
         40% of the total consideration paid in connection with the acquisition;
         or

       - legal opinions as to the tax-free nature of the acquisition cannot
         otherwise be delivered.


       Because the value of the Hilton common stock for tax purposes will be
       determined on the closing date, we will not know at the time of the
       stockholder meeting whether the forward merger structure or the reverse
       merger structure will be used. The structure of the acquisition will
       affect the tax consequences to you of the acquisition. If the forward
       merger structure is used, you will be taxed on any gain realized only to
       the extent of the cash consideration received in exchange for your shares
       of Promus stock. However, if the reverse merger structure is used, you
       will be taxed on any gain realized regardless of the form of
       consideration that you receive in exchange for your shares of Promus
       stock. Details are provided in the joint proxy statement/prospectus.
       Based on current information, we will use the forward merger structure so
       long as the volume weighted average per share sales price of Hilton
       common stock on the closing date is at least $9.84. The volume weighted
       average per share sales price of Hilton stock on October 18, 1999 was
       $8.97. Accordingly, if the closing had occurred on that day, we would
       have used the reverse merger structure and you would have been taxed on
       any gain realized, regardless of the form of consideration you received.


    2.  To transact such other business as may properly come before the special
       meeting or any adjournment or postponement of the meeting.

    YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE ACQUISITION IS
IN THE BEST INTERESTS OF PROMUS AND ITS STOCKHOLDERS AND RECOMMENDS THAT YOU
VOTE TO APPROVE THE ACQUISITION. Each of the items of business to be submitted
to a vote at the Promus meeting is more fully described in this proxy
statement/prospectus, which we urge you to read carefully.


    Stockholders of record on the close of business on October 15, 1999 are
entitled to notice of and to vote at the special meeting and any adjournment or
postponement of the meeting. Approval of the acquisition will require the
affirmative vote of holders of Promus common stock representing a majority of
the outstanding shares of Promus common stock. Stockholders are cordially
invited to attend the special meeting in person.

                  QUESTIONS AND ANSWERS ABOUT THE ACQUISITION

Q: WHAT AM I BEING ASKED TO VOTE UPON?

A: HILTON STOCKHOLDERS:  You are being asked to approve:

    - the merger agreement and the issuance of Hilton common stock in the
      acquisition.

    - the amendment of Hilton's certificate of incorporation to increase the
      authorized number of shares of Hilton common stock from 400 million to 500
      million. If approved, the amendment to the certificate of incorporation
      will take effect only if the acquisition is completed.

    - the amendment to Hilton's by-laws to change the authorized number of
      directors from 12 to a range of 10 to 20, with the exact number to be set
      from time to time by the board of directors. If approved, the amendment to
      the by-laws will take effect regardless of the outcome of the votes on the
      acquisition and the amendment to the certificate of incorporation.

    Approval of the merger agreement and completion of the acquisition are not
    dependent on approval of the proposed amendments to the Hilton certificate
    of incorporation or by-laws.

    PROMUS STOCKHOLDERS:  You are being asked to approve the acquisition and the
    merger agreement, which provides that Promus will become a wholly-owned
    subsidiary of Hilton.

Q: WHAT WILL I RECEIVE IN THE ACQUISITION?

A: HILTON STOCKHOLDERS:  You will not receive any consideration in the
   acquisition.


    PROMUS STOCKHOLDERS:  You will receive, for each share of Promus common
    stock you hold, at your election but subject to proration depending on the
    form of consideration other stockholders elect to receive in the merger,
    either:


    - $38.50 in cash; or


    - not less than 2.9096 shares or more than 3.2158 shares of Hilton common
      stock, depending on the average Hilton common stock price before the
      closing of the acquisition. The formula for calculating the number of
      shares is described in detail on page 69 of this joint proxy
      statement/prospectus.


Q: IF I AM A PROMUS STOCKHOLDER, HOW DO I ELECT THE FORM OF PAYMENT I PREFER?


A: You will receive in a separate mailing a form of election and letter of
   transmittal. You should return your completed and executed form of election
   and letter of transmittal to the exchange agent, together with your Promus
   stock certificates, in the appropriate envelope. DO NOT MAIL YOUR FORM OF
   ELECTION OR YOUR STOCK CERTIFICATES WITH YOUR PROXY. IN ORDER TO BE
   CONSIDERED VALID, YOUR ELECTION MUST BE RECEIVED BY THE EXCHANGE AGENT BY
   5:00 P.M., NEW YORK CITY TIME, ON NOVEMBER 29, 1999.


Q: IF I AM A PROMUS STOCKHOLDER, CAN I MAKE ONE ELECTION FOR SOME OF MY SHARES
   AND ANOTHER ELECTION FOR THE REST?

A: Yes. You may elect to receive a combination of cash and Hilton stock by
   electing cash for some of your Promus shares and Hilton stock for your
   remaining shares, subject to proration.

Q: IF I AM A PROMUS STOCKHOLDER, HOW SHOULD I SEND IN MY STOCK CERTIFICATES?


A: If you make an election of consideration by returning a completed form of
   election, you must send in your Promus stock certificates with your completed
   form of election and letter of transmittal to the exchange agent. If you do
   not make an election, then you must keep your stock certificates until after
   the closing, when you will receive a letter of transmittal describing how you
   may exchange your certificates for acquisition consideration. DO NOT SEND
   YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.


                                      iii
<PAGE>
Q: HOW DOES MY BOARD OF DIRECTORS RECOMMEND THAT I VOTE ON THE PROPOSALS?


A: HILTON STOCKHOLDERS:  The Hilton board of directors unanimously recommends
   that you vote FOR:


    - the merger agreement and the issuance of Hilton common stock in the
      acquisition;

    - the amendment to Hilton's certificate of incorporation; and

    - the amendment to Hilton's by-laws.

    PROMUS STOCKHOLDERS:  The Promus board of directors unanimously recommends
    that you vote FOR the proposal to approve the merger agreement.

Q: WHAT VOTE IS REQUIRED TO APPROVE THE PROPOSALS?

A: HILTON STOCKHOLDERS:  The three proposals to be voted upon by the Hilton
   stockholders will require the following votes:

    - holders of a majority of the shares of Hilton common stock represented at
      the special meeting must approve the merger agreement and the issuance of
      Hilton common stock in the acquisition;

    - holders of a majority of the outstanding shares of Hilton common stock
      must approve the amendment to Hilton's certificate of incorporation to
      increase the authorized number of shares of Hilton common stock; and

    - holders of 75% of the outstanding shares of Hilton common stock must
      approve the amendment to Hilton's by-laws to change the authorized number
      of directors.

    PROMUS STOCKHOLDERS:  Approval of the merger agreement requires the
    affirmative vote of the holders of a majority of the outstanding shares of
    Promus common stock.

Q: WHAT DO I NEED TO DO NOW?

A: VOTING: After you read and consider the information in this document, just
   mail your signed proxy card in the enclosed return envelope as soon as
   possible, so that your shares may be represented at the appropriate
   stockholders meeting. You may also vote by calling the toll-free number on
   your proxy card and following the telephonic procedures for delivering your
   proxy. You should return your proxy card or vote telephonically whether or
   not you plan to attend your stockholders meeting. If you attend your
   stockholders meeting, you may revoke your proxy at any time before it is
   voted and vote in person if you wish.


   ELECTION: If you are a Promus stockholder, you will receive a form of
   election and a letter of transmittal in a separate mailing. To make an
   election as to the form of consideration you would like to receive, you must
   send in your completed form of election to the exchange agent by 5:00 p.m.,
   New York City time, on November 29, 1999.



Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE AFTER I HAVE SENT IN MY PROXY CARD
   OR VOTED BY TELEPHONE?



A: You can change your vote at any time before your proxy is voted at the
   meetings. You can do this in one of three ways. You can send a written notice
   stating that you would like to revoke your proxy. You can also complete and
   submit a new proxy card or vote by telephone at a later date. If you choose
   either of these methods, you must submit your notice of revocation or your
   new proxy card to Hilton or Promus, as the case may be, or vote by telephone,
   before your stockholders meeting. Finally, you can attend your meeting and
   vote in person. Simply attending your meeting, however, will not revoke your
   proxy. If you have instructed a broker to vote your shares, you must follow
   directions received from your broker to change your vote.



Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
   SHARES FOR ME?



A: HILTON STOCKHOLDERS:  Your broker will vote your shares on the proposal to
   approve the merger agreement and the issuance of Hilton common stock in the
   acquisition and


                                       iv
<PAGE>

   the proposal to amend the certificate of incorporation only if you provide
   instructions on how to vote. For the proposal to amend the by-laws, your
   broker may vote your shares without instructions from you. You should follow
   the directions provided by your broker regarding how to instruct your broker
   to vote your shares.



    PROMUS STOCKHOLDERS:  Your broker will vote your shares only if you provide
    instructions on how to vote. You should follow the directions provided by
    your broker regarding how to instruct your broker to vote your shares.


Q: WHAT CONSTITUTES A QUORUM AT THE STOCKHOLDERS' MEETINGS?

A: A quorum is a majority of the outstanding shares entitled to vote which are
   present or represented by proxy at the special meetings. A quorum must exist
   for the transaction of business at the special meeting. If you submit a
   properly executed proxy card or a telephonic proxy, even if you abstain from
   voting, your shares will be considered part of the quorum. Broker non-votes,
   which are shares held by a broker or nominee that are represented at the
   special meeting, but with respect to which the broker or nominee is not
   empowered to vote on a proposal, are included in determining the presence of
   a quorum.

Q: WHO CAN I CALL WITH QUESTIONS?

A: HILTON STOCKHOLDERS:


        D.F. King & Co. at (800) 714-3310.


    PROMUS STOCKHOLDERS:


        Morrow & Co., Inc. at (800) 566-9061.

THE COMPANIES

Hilton Hotels Corporation (page 88).......  Hilton is primarily engaged in the ownership, management
                                            and franchising of hotels. As of September 30, 1999, all
                                            of these properties were located in the United States,
                                            with the exception of 19 hotels which are located in 10

                                            For a detailed description of the factors considered by
                                            the Hilton board of directors and the Promus board of
                                            directors in approving the acquisition, see "The
                                            Acquisition--Reasons for the Acquisition."

Recommendations of Boards of Directors
  (pages 29 and 31).......................  The Hilton board of directors believes that the terms of
                                            the acquisition are fair to and in the best interests of
                                            Hilton's stockholders, has unanimously approved the
                                            acquisition and unanimously recommends that Hilton's
                                            stockholders vote to approve the merger agreement and
                                            the issuance of Hilton common stock in the acquisition.
                                            The Hilton board of directors also unanimously
                                            recommends that Hilton stockholders vote to approve the
                                            amendments to the certificate of incorporation and the
                                            by-laws.

                                            The board of directors of Promus believes that the terms
                                            of the acquisition are fair to and in the best interests
                                            of Promus'

                                            stockholders, has unanimously approved the acquisition
                                            and unanimously recommends that Promus' stockholders
                                            vote to approve the merger agreement and the
                                            transactions contemplated by the merger agreement.

Appraisal Rights (page 66)................  If the acquisition is completed, Promus stockholders who
                                            file a written objection with Promus prior to the Promus
                                            stockholders meeting and do not vote for the acquisition
                                            are entitled to dissenters' appraisal rights under
                                            Delaware law. Hilton stockholders will have no
                                            dissenters' appraisal rights.

STRUCTURE OF THE ACQUISITION (PAGE 55)....  As long as the value, as measured on the closing date,
                                            of the Hilton common stock to be delivered in the
                                            acquisition is at least 40% of the total consideration
                                            paid in connection with the acquisition, the acquisition
                                            will be effected by the forward merger structure, in
                                            which Promus will merge into PRH Acquisition, a
                                            wholly-owned subsidiary of Hilton, with PRH Acquisition
                                            being the surviving corporation.

                                            However, we will use the reverse merger structure in
                                            which PRH Acquisition will merge into Promus, with
                                            Promus being the surviving corporation and a
                                            wholly-owned subsidiary of Hilton, if the value of the
                                            shares of Hilton common stock to be delivered in the
                                            acquisition is less than 40% of the total consideration
                                            paid in connection with the acquisition or if legal
                                            opinions as to the tax-free nature of the transaction
                                            cannot otherwise be delivered. The purpose of this
                                            modification to the structure is to avoid the
                                            substantial corporate level tax that would result if the
                                            acquisition were to be structured as a forward merger
                                            and were to fail to satisfy the requirements for a
                                            tax-free reorganization under Section 368(a) of the
                                            Internal Revenue Code.

                                            Because the value of the shares of Hilton common stock
                                            for purposes of the 40% test will be determined on the
                                            closing date, we will not know at the time of the
                                            stockholder meeting whether the forward merger structure
                                            or the reverse merger structure will be used. The
                                            structure of the acquisition will affect the tax
                                            consequences of the acquisition to Promus stockholders.
                                            If the forward merger structure is used, Promus
                                            stockholders will be taxed on any gain realized only to
                                            the extent of cash received in exchange for their shares
                                            of Promus stock. However, if the reverse merger
                                            structure is used, Promus stockholders will be taxed on
                                            any gain realized regardless of the form of
                                            consideration that they receive in exchange for their
                                            shares of Promus stock. Based on current information,
                                            the forward merger structure will be used so long as the
                                            volume weighted average per share sales price of Hilton
                                            common stock on the closing date is at least $9.84. The
                                            volume weighted average per share sales price of Hilton
                                            stock on October 18, 1999 was $8.97. Accordingly, if the
                                            closing had occurred on that date, we would have used
                                            the reverse merger structure. Details of the tax

ACQUISITION STEPS

General...................................  The rights and obligations of all parties under the
                                            merger agreement are governed by the exact language of
                                            the merger agreement, not the description in this joint
                                            proxy statement/ prospectus. A copy of the merger
                                            agreement is included in this joint proxy
                                            statement/prospectus as Appendix A.

Election of Cash or Hilton Shares
  (page 68)...............................  Subject to the requirement that 55% of the Promus shares
                                            be converted into $38.50 in cash per share and the
                                            balance be converted into Hilton common stock, Promus
                                            stockholders will have the right to elect to receive
                                            either cash or Hilton common stock for each share of
                                            Promus common stock. Subject to proration, a Promus
                                            stockholder may elect to receive all cash, all stock or
                                            a combination of cash and stock for Promus shares.
                                            Promus is sending a form of election and letter of
                                            transmittal to its stockholders in a separate mailing.
                                            Dissenting stockholders must follow the procedures
                                            provided under Delaware law and are not entitled to make
                                            an election. Promus stockholders must submit their
                                            completed forms of election to the exchange agent, First
                                            Union National Bank, by the election deadline of
                                            5:00 p.m., New York City time, on November 29, 1999.
                                            Stockholders electing the form of consideration to be
                                            received must include the Promus stock certificates that
                                            represent the shares subject to their election.

                                            Promus stockholders who do any of the following will be
                                            deemed to have made a non-election:

                                                - fail to submit a form of election prior to the
                                                  election deadline;

                                                - submit and then revoke their forms of election and
                                                  do not re-submit forms of election and other
                                                  required documents that are timely received by the
                                                  exchange agent; or

                                                - submit forms of election without corresponding
                                                  certificates or a guarantee of delivery.

                                            Stockholders who are deemed to have made a non-election
                                            will receive cash or shares of Hilton common stock as
                                            described below.

Cash Election (page 68)...................  Promus stockholders who make a cash election will
                                            receive $38.50 for each share of Promus common stock
                                            covered by the cash election, subject to proration
                                            described below.

Stock Election (page 68)..................  Promus stockholders who have made a stock election will
                                            receive shares of Hilton common stock for each share of
                                            Promus common stock covered by the stock election,

                                            common stock will depend on an exchange ratio determined
                                            by the average of the volume weighted average per share
                                            sales price of Hilton common stock on the NYSE for 20
                                            trading days selected by lot from the 30 trading days
                                            ending on the fifth trading day before the closing of
                                            the acquisition. The exchange ratio will be fixed as
                                            follows:

                                                - If the average Hilton stock price is between
                                                  $11.97 and $13.23, the exchange ratio will equal
                                                  $38.50 divided by the average Hilton stock price.

                                                - If the average Hilton stock price is more than
                                                  $13.23, the exchange ratio will be 2.9096.

                                                - If the average Hilton stock price is less than
                                                  $11.97, the exchange ratio will be 3.2158.

                                            We will issue a press release prior to closing that
                                            announces the exchange ratio.

Cash or Stock Proration (page 69).........  Hilton has agreed to pay for 55% of the outstanding
                                            shares of Promus common stock in cash and to pay for the
                                            remaining 45% of the outstanding shares of Promus common
                                            stock in shares of Hilton common stock. If Promus
                                            stockholders as a group elect to receive more cash or
                                            more shares of Hilton common stock in the acquisition
                                            than the amount available, those stockholders who make
                                            an election for the oversubscribed category will not
                                            receive the acquisition consideration entirely in the
                                            form that they elect. Instead, their election will be
                                            prorated as described below, so that on an overall basis
                                            Hilton will pay the acquisition consideration in the
                                            agreed-upon percentages of cash and shares of Hilton
                                            common stock.

                                            If Promus stockholders make cash elections for more than
                                            55% of the outstanding shares of Promus common stock,
                                            the acquisition consideration will be allocated as
                                            follows:

                                                - shares for which a stock election or a
                                                  non-election has been made will be converted into
                                                  Hilton common stock; and

                                                - shares for which a cash election has been made
                                                  will be converted into both cash and the Hilton
                                                  common stock on a pro rata basis in accordance
                                                  with the merger agreement. The maximum permitted
                                                  number of shares, as described above, will be
                                                  converted into cash. The remaining shares will be
                                                  converted into shares of Hilton common stock.

Promus Employee and Director Stock Options
  (page 72)...............................  Generally, each outstanding Promus employee and director
                                            stock option will be canceled in the acquisition.
                                            Payment for each stock option will equal an amount of
                                            cash determined by multiplying:

                                                - the excess, if any, of $38.50 over the exercise
                                                  price of the Promus stock option by

                                                - the number of Promus shares the option holder
                                                  could have purchased, assuming full vesting of the
                                                  option, had the holder exercised the option in
                                                  full immediately prior to the effective time.

                                            If the payment is made at the closing, Promus will pay
                                            the holder of the stock option. If the payment is made
                                            after the closing, Hilton will pay the holder.

Opinions of Financial Advisors (pages 39,
  46 and 51)..............................  In deciding to approve the proposed acquisition, the
                                            Hilton board considered the opinion of Morgan Stanley &
                                            Co. Incorporated that, as of the date of the opinion,
                                            the consideration that Hilton will pay in the
                                            acquisition pursuant to the merger agreement was fair to
                                            Hilton from a financial point of view. In addition, the
                                            Hilton board considered the opinion of Donaldson,
                                            Lufkin & Jenrette Securities Corporation, that, as of
                                            the date of the opinion, the consideration that Hilton
                                            will pay in the acquisition, taken as a whole, was fair
                                            to Hilton and its stockholders from a financial point of
                                            view. The opinions are subject to the qualifications and
                                            limitations referred to in their text. We attach copies

                                            Promus' financial advisor, Salomon Smith Barney Inc.,
                                            has given a written opinion to the Promus board that, as
                                            of the date of the opinion, the acquisition
                                            consideration for the Promus common stock, taken as a
                                            whole, was fair to Promus stockholders from a financial
                                            point of view. The opinion is subject to the
                                            qualifications and limitations referred to in the
                                            opinion. We attach a copy of the Salomon Smith Barney

                                                - if the forward merger structure is used, Hilton
                                                  and Promus receive legal opinions as to tax

Termination of the Merger Agreement
  (page 75)...............................  Both companies may mutually agree to terminate the
                                            merger agreement at any time without completing the
                                            acquisition. Either company may terminate the merger
                                            agreement if:

                                                (1) the acquisition is not completed by March 31,
                                                2000, unless funds are not available to Hilton
                                                    because of a Year 2000 problem that causes a
                                                    material adverse change in the financial
                                                    markets, in which case the deadline is extended
                                                    to April 30, 2000. Neither Hilton nor Promus may
                                                    terminate the merger agreement on this basis,
                                                    however, if its breach of the merger agreement
                                                    results in the acquisition not being completed
                                                    by the applicable deadline;

                                                (2) a court or other governmental authority issues a
                                                final, non-appealable order prohibiting the
                                                    acquisition, or any law or regulation makes

                                                    may terminate the merger agreement on this

                                                (3) the Hilton stockholders or the Promus
                                                stockholders do not approve the acquisition.

                                            In addition, Hilton may terminate the merger agreement
                                            if any of the following events occurs:

                                                (4) any person or group of persons acting in
                                                concert, other than Hilton or its affiliates,
                                                    acquires beneficial ownership of more than 50%
                                                    of the shares of Promus common stock;

                                                (5) the Promus board of directors withdraws or
                                                amends in a manner adverse to Hilton its
                                                    recommendation of the acquisition and approves a
                                                    proposal deemed by the Promus board of directors
                                                    to be superior to the Hilton acquisition, as
                                                    described under the "The Merger
                                                    Agreement--Termination of the Merger Agreement";
                                                    or

                                                (6) Promus enters into or announces its intention to
                                                    enter into an agreement with a third party based
                                                    on a superior proposal.

                                            Furthermore, Promus may terminate the merger agreement
                                            if any of the following events occurs:

                                                (7) the Promus board of directors approves a
                                                superior, unsolicited proposal or withdraws or
                                                    amends in a manner adverse to Hilton its
                                                    recommendation of the acquisition, so long as
                                                    Promus has complied with the requirements of the
                                                    non-solicitation, board recommendation, notice
                                                    and termination fee provisions of the merger
                                                    agreement and Hilton has not offered adjustments
                                                    to the merger agreement that would allow the
                                                    Promus board of directors to recommend the
                                                    acquisition by Hilton; or

                                                (8) the Hilton board of directors withdraws or
                                                amends in a manner adverse to Promus its
                                                    recommendation of the acquisition.

Termination Fees and Expenses
  (page 76)...............................  Promus has agreed to pay Hilton a termination fee of
                                            $75 million if:

                                                - the merger agreement is terminated in the
                                                  circumstances described in paragraphs (4), (5),

                                            Hilton has agreed to pay Promus a termination fee of
                                            $150 million if Hilton or Promus terminates the merger

No Solicitation (page 77).................  The merger agreement prohibits Promus from negotiating
                                            or engaging in discussions with a third party regarding
                                            an acquisition transaction with Promus unless:

                                                - Promus has received an unsolicited proposal for
                                                  the transaction from that third party;

                                                - Promus has notified Hilton about the proposal;

                                                - the Promus board of directors determines in good
                                                  faith that, based on the terms and conditions
                                                  contained in the proposal, the proposal could
                                                  reasonably be expected to constitute a superior
                                                  proposal, as described in the merger agreement;
                                                  and

                                                - the third party executes a confidentiality
                                                  agreement with terms substantially similar to
                                                  those contained in the confidentiality agreement
                                                  between Hilton and Promus.

Accounting Treatment (page 65)............  Hilton will treat the acquisition as a purchase for
                                            accounting and financial reporting purposes.

Certain Federal Income Tax Consequences of
  the Acquisition (page 60)...............  The tax consequences resulting from the acquisition will
                                            differ depending on whether the forward merger structure
                                            or the reverse merger structure is used. Since the
                                            structure that we will use to complete the acquisition
                                            will depend on several factors, including, in
                                            particular, the value of Hilton common stock on the
                                            closing date, we will not know at the time of the
                                            stockholder meeting which structure will be used. As a
                                            result, Promus stockholders will not know which of the
                                            alternative tax consequences described below will be
                                            applicable to them at the time they vote on the
                                            acquisition.

                                            IF THE FORWARD MERGER STRUCTURE IS USED, THE ACQUISITION
                                            WILL QUALIFY AS A REORGANIZATION UNDER SECTION 368(a) OF
                                            THE INTERNAL REVENUE CODE. In that case, generally:

                                                - a Promus stockholder who receives solely Hilton
                                                  common stock in exchange for shares of Promus
                                                  common stock will not recognize any gain or loss,
                                                  except for any gain or loss attributable to cash
                                                  received in lieu of fractional shares;

                                                - a Promus stockholder who receives solely cash in
                                                  exchange for shares of Promus common stock will be
                                                  required to recognize gain, and should be
                                                  permitted to recognize loss, equal to the
                                                  difference between the amount of cash received by
                                                  the stockholder and the stockholder's adjusted tax
                                                  basis in the shares of Promus common stock that
                                                  the stockholder surrenders in the acquisition; and

                                                  common stock and cash in exchange for shares of
                                                  Promus common stock will not recognize loss, but
                                                  will recognize gain to the extent of the lesser
                                                  of:

                                                    -- the cash received; or

                                                    -- the excess of the sum of the fair market
                                                    value of the Hilton common stock and the amount
                                                      of cash received over the stockholder's
                                                      adjusted tax basis in the shares of Promus
                                                      common stock that the stockholder surrenders
                                                      in the acquisition.

                                            Under certain circumstances, gain recognized by a Promus
                                            stockholder may be treated as a dividend, and thus as
                                            ordinary income, rather than as capital gain.

                                            IF THE REVERSE MERGER STRUCTURE IS USED, THE ACQUISITION
                                            WILL NOT QUALIFY AS A REORGANIZATION UNDER SECTION
                                            368(a) OF THE INTERNAL REVENUE CODE, BUT RATHER WILL BE
                                            TREATED AS A SALE OF PROMUS STOCK FULLY TAXABLE TO THE
                                            PROMUS STOCKHOLDERS. In that case, each Promus
                                            stockholder will recognize gain or loss equal to the
                                            difference between:

                                                - the cash received plus the fair market value of
                                                  the Hilton common stock received; and

                                                - the stockholder's adjusted tax basis in the shares
                                                  of Promus common stock that the stockholder
                                                  surrenders in the acquisition.

                                            We would use the reverse merger structure to avoid the
                                            substantial corporate level tax that would result if the
                                            acquisition were to be structured as a forward merger
                                            and were to fail to satisfy the requirements for a
                                            tax-free reorganization under Section 368(a) of the
                                            Internal Revenue Code.

            SELECTED HISTORICAL AND PRO FORMA FINANCIAL INFORMATION

HISTORICAL FINANCIAL INFORMATION

    We are providing or incorporating by reference in this joint proxy
statement/prospectus selected historical financial information for Hilton and
Promus to help you in your analysis of the financial aspects of the acquisition.


    We derived this information from the audited and unaudited financial
statements of Hilton and Promus for the periods presented. The information is
only a summary and you should read it together with the financial information
included or incorporated by reference in this joint proxy statement/ prospectus.
See "Where You Can Find More Information" on page 94.


UNAUDITED PRO FORMA FINANCIAL INFORMATION

    We are also providing unaudited pro forma financial information in this
joint proxy statement/ prospectus to show you how Hilton might have looked if
the acquisition had been completed on January 1, 1998 for results of operations
purposes and on June 30, 1999 for balance sheet purposes.

    The pro forma financial information was prepared using the purchase method
of accounting.

    If Hilton had actually completed the acquisition on those dates, the
acquired companies might have performed differently. You should not rely on the
pro forma financial information as an indication of the results that Hilton
would have achieved if the acquisition had taken place earlier or the future
results that Hilton will experience after completion of the acquisition.

EQUIVALENT SHARE DATA


    The following information shows the effect of the acquisition from the
perspective of an owner of Promus common stock. The information was computed by
multiplying the Hilton pro forma information by an assumed exchange ratio of
3.2158 shares of Hilton common stock for each share of Promus common stock.

- --------------------------


(1) Pro forma results do not reflect any operational efficiencies, cost savings
    associated with greater economies of scale or revenue enhancement
    opportunities which Hilton expects to achieve after the acquisition. Hilton
    expects to realize pre-tax annual revenue enhancements and pre-tax cost
    savings, including operating efficiencies, totaling approximately
    $90 million upon full integration of Promus. Hilton expects to realize
    approximately $55 million of benefits in 2000, and the entire $90 million of
    benefits beginning in 2001. However, the estimated benefits are based on
    projections and assumptions, not actual experiences. As a result, Hilton's
    ability to realize these benefits could be adversely impacted by
    difficulties integrating Promus into Hilton, the inability to achieve
    certain economies of scale or other risks associated with achieving
    projected revenues and cost savings. Hilton cannot assure you that these
    revenue enhancements and cost savings will be achieved.



(2) Includes after-tax non-recurring Promus charges totaling $5 million in
    employment-related expenses associated with the management change following
    the 1997 Promus/Doubletree merger.


(3) EBITDA is earnings before interest, taxes, depreciation, amortization and
    non-cash items. EBITDA can be computed by adding depreciation, amortization,
    interest and dividend income from investments related to operating
    activities and non-cash items to operating income. EBITDA is presented
    supplementally because management believes it allows for a more complete
    analysis of results of operations. Non-cash items, such as asset write-downs
    and impairment losses, are excluded from EBITDA as these items do not impact
    EBITDA on a recurring basis. You should not consider this information as an
    alternative to any measure of performance reported under generally accepted
    accounting principles, such as operating income or income from continuing
    operations, nor should you consider it as an indicator of the overall
    financial performance of either Hilton or Promus before the acquisition or
    after the acquisition. Our method of calculating EBITDA may be different
    from methods used by other companies, and therefore comparability may be
    limited.

(4) Includes $625 million of long-term debt which, although allocated under a
    debt assumption agreement to Park Place Entertainment Corporation, remains
    the legal obligation of Hilton. At the time of the spin-off of Hilton's
    gaming operations to its stockholders on December 31, 1998, Park Place
    assumed and agreed to pay 100% of the amount of each payment required to be
    made by Hilton under the terms of the indentures governing Hilton's
    $300 million 7.375% Senior Notes due 2002 and its $325 million 7% Senior
    Notes due 2004. These notes remain in Hilton's long-term debt balance and a
    long-term receivable from Park Place in an equal amount is included in
    Hilton's consolidated balance sheet. If the interest rate on these notes
    increases due to specified Hilton actions, Hilton will be required to
    reimburse Park Place for the increase.


(5) Includes after-tax non-recurring Hilton charges totaling $10 million,
    representing Hilton's proportionate share of costs associated with the
    spin-off of Park Place, and after-tax non-recurring Promus net charges
    aggregating $26 million, including a $27 million charge for severance and
    employment related expenses associated with the 1997 Promus/Doubletree
    merger, a $6 million charge for accrued severance and employment related
    expenses associated with the resignations of Promus' Chief Executive Officer
    and President in 1998, gains of $6 million on the sale of real estate and
    securities and a gain of $1 million on the sale of excess joint venture
    land.

SELECTED HISTORICAL FINANCIAL INFORMATION--HILTON

    In the table below, Hilton provides you with its selected historical
financial data. Hilton prepared this information using its consolidated
financial statements as of the dates indicated and for each of the fiscal years
in the five-year period ended December 31, 1998 and the six-month periods ended
June 30, 1999 and 1998. Hilton derived the results of operations data below for
each of the five years in the period ended December 31, 1998, and the balance
sheet data at December 31, 1998 from financial statements audited by Arthur
Andersen LLP. Hilton derived the remaining data from unaudited financial
statements. In the opinion of Hilton management, the unaudited data reflect all
adjustments, consisting only of normal or recurring adjustments, necessary to
present the data fairly for each interim period.


    When you read the selected historical financial information, you should read
along with it the historical financial statements and accompanying notes that
Hilton has included in its Annual Report on Form 10-K for the year ended
December 31, 1998. You can obtain this report by following the instructions

(1) Includes after-tax non-recurring charges totaling $10 million, representing
    Hilton's proportionate share of costs associated with the spin-off of Park
    Place on December 31, 1998.

(2) Includes after-tax non-recurring charges totaling $10 million, primarily
    related to the write-off of net costs related to Hilton's efforts to acquire
    ITT Corporation.

(3) Includes after-tax non-recurring charges totaling $24 million, primarily
    related to the write-down of certain investments and notes receivable to
    estimated fair market value.

(4) EBITDA is earnings before interest, taxes, depreciation, amortization and
    non-cash items. EBITDA can be computed by adding depreciation, amortization,
    interest and dividend income from investments related to operating
    activities and non-cash items to operating income. EBITDA is presented
    supplementally because management believes it allows for a more complete
    analysis of results of operations. Non-cash items, such as asset write-downs
    and impairment losses, are excluded from EBITDA as these items do not impact
    operating results on a recurring basis. Hilton pre-tax non-cash items for
    the year ended December 31, 1997 resulted in a

                                       18
<PAGE>
    credit of $2 million, primarily from the reversal of a 1996 non-cash
    write-down. Hilton pre-tax non-cash items for the year ended December 31,
    1996 totaled $22 million and relate to the write-down of certain investments
    and notes receivable to estimated fair market value. You should not consider
    this information as an alternative to any measure of performance reported
    under generally accepted accounting principles, such as operating income or
    income from continuing operations, nor should you consider it as an
    indicator of the overall financial performance of Hilton. Our method of
    calculating EBITDA may be different from the methods used by other
    companies, and therefore comparability may be limited.

(5) Includes $625 million of long-term debt which, although allocated under a
    debt assumption agreement to Park Place, remains the legal obligation of
    Hilton. At the time of the spin-off of Hilton's gaming operations to its
    stockholders, Park Place assumed and agreed to pay 100% of the amount of
    each payment required to be made by Hilton under the terms of the indentures
    governing Hilton's $300 million 7.375% Senior Notes due 2002 and its
    $325 million 7% Senior Notes due 2004. These notes remain in Hilton's
    long-term debt balance and a long-term receivable from Park Place in an
    equal amount is included in Hilton's consolidated balance sheet. If the
    interest rate on these notes increases due to specified Hilton actions,
    Hilton will be required to reimburse Park Place for the increase.

SELECTED HISTORICAL FINANCIAL INFORMATION--PROMUS

    In the table below, Promus provides you with its selected historical
financial data. Promus prepared this information using its consolidated
financial statements as of the dates indicated and for each of the fiscal years
in the five-year period ended December 31, 1998 and the six-month periods ended
June 30, 1999 and 1998. The information below reflects the December 19, 1997,
merger between Promus and Doubletree Corporation. This merger was accounted for
as a pooling of interests, and all periods before and including fiscal 1997 were
restated to combine the historical results of Promus and Doubletree.

    Promus derived the results of operations data below for each of the four
years in the period ended December 31, 1998, and the balance sheet data at
December 31, 1998 from financial statements audited by Arthur Andersen LLP, with
certain reliance placed on other auditors. Promus derived the remaining data
from unaudited financial statements. In the opinion of Promus' management, the
unaudited data reflect all adjustments, consisting only of normal or recurring
adjustments, necessary to present the data fairly for each interim period.


    When you read the selected historical financial information, you should read
along with it the historical financial statements and accompanying notes that
Promus has included in its Annual Report on Form 10-K for the year ended
December 31, 1998. You can obtain this report by following the instructions
under "Where You Can Find More Information" on page 94.

(6) Before June 30, 1995, Promus was a division of The Promus Companies
    Incorporated. In June 1995, Promus was spun off by its parent. For periods
    before the spin-off, weighted average shares outstanding are assumed to be
    equal to the actual shares outstanding at the spin-off. For the period
    January 1, 1994 through June 30, 1994, the date of Doubletree's initial
    public offering, shares outstanding were assumed to be equal to the number
    of shares issued on June 30, 1994.


(7) EBITDA is earnings before interest, taxes, depreciation, amortization and
    non-cash items. EBITDA can be computed by adding depreciation, amortization,

    the year ended December 31, 1997 totaled $32 million and relate to the
    provision for business combination expenses. Promus' presentation of EBITDA
    has been changed to conform with Hilton's presentation. You should not
    consider this information as an alternative to any measure of performance
    reported under generally accepted accounting principles, such as operating
    income or income from continuing operations, nor should you consider it as

                                  RISK FACTORS

    You should consider the following risk factors, together with the other
information included and incorporated by reference in this joint proxy
statement/prospectus, in deciding whether to vote to approve the acquisition.

RISKS RELATING TO THE ACQUISITION

    WE MAY EXPERIENCE DIFFICULTIES INTEGRATING PROMUS WITH HILTON


    After the acquisition's completion, we intend to integrate the operations of
Promus with those of Hilton. We cannot assure you that Hilton will be able to
integrate the operations without encountering difficulties. These difficulties
could include integrating different business strategies with respect to
franchising, managing, owning and leasing hotels; integrating personnel with
disparate business backgrounds and corporate cultures; integrating different
reservations systems and other technology; and managing relationships with hotel
owners, franchisees and other business parties. The integration of operations
may temporarily distract management from the day-to-day business of Hilton after
the acquisition. Hilton also may lose key Promus or Hilton personnel because of
the acquisition and the consolidation of Promus' corporate headquarters with
Hilton's. For these reasons, Hilton cannot assure you that it will be able
successfully to integrate the Promus operations in the anticipated time frame.


    WE MAY NOT ACHIEVE THE EXPECTED SYNERGIES FROM THE ACQUISITION


    Hilton's management believes that the acquisition of Promus will allow
Hilton to achieve approximately $90 million of pre-tax annual synergistic
benefits once Promus is fully integrated. Hilton expects to realize
approximately $55 million of benefits in 2000, and the entire $90 million of
benefits beginning in 2001. The anticipated benefits relate to operational
efficiencies, cost savings associated with greater economies of scale and
revenue enhancement opportunities. However, the estimated benefits are based on
projections and assumptions, not actual experience. As a result, Hilton cannot
assure you that it will realize the anticipated benefits. Hilton's ability to
realize these benefits could be adversely impacted by difficulties in
integrating Promus into Hilton, the inability to achieve certain economies of
scale and other risks associated with achieving expected revenue enhancements
and cost savings.


    PROMUS STOCKHOLDERS MAY RECEIVE HILTON COMMON STOCK THAT HAS A VALUE OF LESS
     THAN $38.50


    No assurances can be given to Promus stockholders of the value of the shares
of Hilton common stock to be issued in the merger. Upon completion of the
acquisition, 45% of the shares of Promus common stock will be exchanged for a
number of shares of Hilton common stock that will be determined as described in
this joint proxy statement/prospectus, but in no case more than 3.2158 shares of
Hilton common stock per Promus share. The 3.2158 exchange ratio will apply if
the average Hilton stock price is less than $11.97 per share. Therefore, if the
value of Hilton common stock is less than $11.97 per share, the value of Hilton
common stock exchanged for Promus shares will be less than $38.50 per share. The
volume weighted average per share sales price of the Hilton stock on
October 18, 1999 was $8.97. Neither party is permitted to terminate the merger
agreement because of changes in the market price of Hilton or Promus common
stock. You are urged to obtain recent market quotations for Hilton and Promus
common stock. We cannot predict or give any assurances as to the market price of
Hilton common stock at any time before or after the acquisition.


    PROMUS STOCKHOLDERS MAY RECEIVE ACQUISITION CONSIDERATION IN A FORM THAT
     DIFFERS FROM THEIR ELECTIONS OF CASH OR STOCK CONSIDERATION


    Although Promus stockholders may elect to receive cash, Hilton common stock,
or a combination of cash and stock in exchange for their shares of Promus common
stock, 55% of the outstanding shares


                                       23
<PAGE>

of Promus common stock will be converted into cash and 45% of the outstanding
shares of Promus common stock will be converted into Hilton common stock. If a
Promus stockholder elects to receive cash, and cash elections are
oversubscribed, then the holder will receive a portion of the acquisition
consideration in shares of Hilton common stock. As described in the preceding
risk factor, the value of the stock consideration delivered at closing may be
below $38.50 per Promus share. Similarly, if a holder elects to receive Hilton
common stock and stock elections are oversubscribed, then the holder will
receive a portion of the acquisition consideration in cash. The form of the
consideration ultimately received by a Promus stockholder will depend upon the
election and proration procedures described in this joint proxy
statement/prospectus and the elections made by other Promus stockholders.


    PROMUS STOCKHOLDERS WILL NOT KNOW THE FEDERAL INCOME TAX CONSEQUENCES TO
     THEM OF THE ACQUISITION AT THE TIME THEY MAKE AN ELECTION AS TO THE FORM OF
     CONSIDERATION OR AT THE TIME THEY VOTE


    The federal income tax consequences of the acquisition to each Promus
stockholder will vary depending on whether we complete the acquisition through
the use of the forward merger structure or the reverse merger structure. These
tax consequences will also vary depending on whether a Promus stockholder
receives cash, stock, or a combination of cash and stock in exchange for the
stockholder's shares of Promus common stock. At the time that a Promus
stockholder makes an election as to the form of the consideration to be received
in the acquisition and at the time that the stockholder votes on the
acquisition, the stockholder will not know if, or to what extent, the
consideration proration procedures will be applicable. Therefore, a Promus
stockholder will not know at those times the extent to which the stockholder's
elected forms of acquisition consideration will be given effect. Additionally,
at the time of making the election and voting on the acquisition, the Promus
stockholders will not know which of the two alternative structures we will use
to complete the acquisition. Accordingly, although the federal tax treatment of
both of these alternative structures is described in this joint proxy
statement/prospectus, the actual federal income tax consequences to each Promus
stockholder will not be ascertainable at that time. Based on the volume weighted
per share sales price of Hilton stock of $8.97 on October 18, 1999, if the
closing had occurred on that date, we would have used the reverse merger
structure. However, the structure actually used will not be determined until the
closing date.


    THIS ACQUISITION MAY LIMIT HILTON'S ABILITY TO OPERATE THE COMBINED BUSINESS
     IN SOME GEOGRAPHIC AREAS


    A number of Hilton's and Promus' franchise, management and license
agreements purport to restrict Hilton's or Promus' right to own, manage or
franchise additional hotels, or in some cases brands, in a specified geographic
area. After the acquisition, Hilton will own, manage or franchise additional
hotels in some of these areas and, consequently, may be in violation of some of
these purported restrictions. If Hilton is unable to renegotiate successfully or
otherwise resolve the effects of these restrictions, the agreements may be
terminated, Hilton may be required to pay monetary damages or Hilton may be
required to sell certain of these hotels. We cannot predict or give any
assurances that Hilton will be able to renegotiate successfully or otherwise
resolve the effects of these restrictions. See "The Acquisition--Recent
Litigation" at page 66 for a description of a recently filed lawsuit which
alleges that the acquisition will violate the territorial restriction in one of
Hilton's hotel management agreements.


    IF SUFFICIENT FUNDS ARE NOT AVAILABLE TO HILTON, THE ACQUISITION WILL LIKELY
     NOT BE CONSUMMATED


    The acquisition's completion is conditioned upon funds being available to
Hilton in an amount sufficient to pay the cash component of the consideration to
the Promus stockholders, to refinance certain existing indebtedness of Promus
and to pay fees and expenses. If these funds are not available and Hilton is not
in material breach of the financing-related provisions of the merger agreement
or the provisions of Hilton's financing agreements, Hilton will not be required
to complete the acquisition. Hilton has obtained a fully underwritten commitment
from Bank of America N.A. for financing that,


                                       24
<PAGE>

together with existing credit capacity and available cash, Hilton believes is
sufficient to complete the acquisition. That commitment is subject to customary
closing conditions, including a provision that no material adverse change in or
material disruption of conditions in the financial, banking or capital markets
has occurred. We cannot assure you that all of the conditions to the
consummation of the financing will be met. We expect to close the acquisition
before December 31, 1999. We cannot predict what impact the Year 2000 issue,
relating to the ability of computer software, hardware and hardware systems to
properly process data containing dates on or after January 1, 2000, may have on
the financial markets generally. If the financing under the commitment were not
available, Hilton would attempt to obtain financing from other sources, although
Hilton cannot assure you that it would be able to do so on favorable terms or at
all. If Hilton's costs of financing are greater than anticipated, its future
results may be adversely affected. If we do not complete the acquisition because
sufficient funds are not available to Hilton other than as a result of a breach
of any representation or warranty attributable solely to facts and circumstances
relating to Promus, Hilton would be obligated to pay Promus a fee of
$150 million if other conditions to the closing of the acquisition that are
specified in the merger agreement have been satisfied. For further information,
see "The Merger Agreement--Termination Fees and Expenses" on page 76.


    WE CANNOT ASSURE YOU THAT THIS ACQUISITION WILL NOT IMPACT THE TAX
     CONSEQUENCES OF HILTON'S 1998 SPIN-OFF OF PARK PLACE


    On December 31, 1998, Hilton distributed the stock of Park Place
Entertainment Corporation, then a wholly-owned subsidiary of Hilton, to its
stockholders. Hilton received a ruling from the Internal Revenue Service to the
effect that the Park Place distribution was tax-free to Hilton and its
stockholders pursuant to Sections 355(a) and (c) of the Internal Revenue Code.
However, despite that ruling, the Park Place distribution would not be a
tax-free distribution as far as Hilton is concerned if the distribution were
deemed to be part of a plan or series of related transactions, pursuant to which
one or more persons acquired, directly or indirectly, stock representing a 50%
or greater interest in Hilton or Park Place, as set forth in Section 355(e) of
the Internal Revenue Code. Hilton has received an opinion from its counsel to
the effect that the acquisition will not cause the Park Place distribution to
fail to qualify as a tax-free transaction based on the application of Section
355(e) of the Internal Revenue Code. Moreover, as a condition to the obligation
of Promus to complete the acquisition, the opinion must be confirmed as of the
closing of the acquisition. In rendering the tax opinions, counsel has relied
and will rely on factual representations and statements made by Hilton. Any
inaccuracy or change with respect to the factual representations or statements
could adversely affect the conclusions reached in the opinions. The tax opinion
received at signing does, and the tax opinion to be delivered at closing will,
represent tax counsel's best judgment as to the effect of the acquisition on the
Park Place distribution, but will not be binding on the Internal Revenue
Service. There can be no assurance that the Internal Revenue Service will not
contest the conclusions reached in the opinions of counsel. If Hilton's
acquisition of Promus or other transactions involving acquisition of the stock
or assets of Hilton or Park Place were to affect the tax-free nature of the Park
Place distribution, Hilton would be subject to tax on the gain inherent in the
stock of Park Place at the time of the distribution. Hilton would, however, be
entitled to indemnification from Park Place if Park Place entered into a
transaction that caused the distribution to fail to comply with Section 355.


    PROMUS STOCKHOLDERS WILL HAVE A REDUCED OWNERSHIP AND VOTING INTEREST AFTER
     THE ACQUISITION

    After the acquisition's completion, Promus stockholders will own a
significantly smaller percentage of Hilton than they currently own of Promus.
Consequently, Promus stockholders may be able to exercise less influence over
the management and policies of Hilton than they currently exercise over the
management and policies of Promus.

                                       25
<PAGE>
    PROMUS' DIRECTORS AND OFFICERS HAVE INTERESTS THAT DIFFER IN SOME RESPECTS
     FROM PROMUS STOCKHOLDERS


    In considering the recommendation of the Promus board of directors to
approve the acquisition, Promus stockholders should consider that some of
Promus' directors and officers have interests in the acquisition that differ
from, or are in addition to, their interests as Promus stockholders. Promus'
directors and officers may receive benefits from the acquisition not available
to Promus stockholders generally. These benefits include the receipt of cash in
connection with Promus stock options, potential payments under Promus' severance
agreements and the continuation of existing indemnification policies and
agreements. These and additional interests are described under the headings "The
Acquisition--Interests of Certain Persons in the Acquisition" on page 56 and
"Hilton After the Acquisition--Management" on page 78.


RISKS RELATING TO THE BUSINESS OF HILTON AFTER THE ACQUISITION

    HILTON WILL HAVE TO COMPETE FOR CUSTOMERS, MANAGEMENT CONTRACTS, LEASES AND
     FRANCHISE AGREEMENTS

    Hilton's hotels will compete for customers with a wide range of lodging
facilities offering full-service, limited-service and all-suite lodging options
to the public. Companies in the lodging industry compete based on factors such
as room rates, quality of accommodations, name recognition, service levels,
marketing programs and convenience of location. We cannot assure you that our
competitors will not significantly expand or improve facilities, adjust prices
or implement new or improved marketing programs in markets in which Hilton's
hotels compete so that Hilton's operations are adversely affected. Hilton also
will compete for management contracts, leases and franchise agreements with
other hotel management companies and national brand franchisers, including
Marriott, Starwood, Hyatt, Cendant and Wyndham, as well as hotel management
companies, including some that do not have their own brand. We cannot assure you
that Hilton will be successful in retaining current, or competing for
additional, management contracts, leases or franchise agreements.

    HILTON MAY EXPERIENCE ADVERSE EFFECTS OR INCUR LIABILITY AS A RESULT OF ITS
     OWNERSHIP AND LEASING OF REAL ESTATE

    Hilton owns and leases, and will continue to own and lease, hotels and will
therefore be subject to varying degrees of risk generally related to leasing and
owning real estate. In addition to general risks related to the lodging
industry, these risks include liability for long-term lease obligations, changes
in national, regional and local economic conditions, local real estate market
conditions, changes in interest rates and in the availability, cost and terms of
financing, the potential for uninsured casualty and other losses, the impact of
present or future environment legislation and compliance with environmental
laws, and adverse changes in zoning laws and other regulations, many of which
are beyond the control of Hilton. Additionally, real estate investments are
relatively illiquid, which means that the ability of Hilton to vary its
portfolio of hotels in response to changes in economic and other conditions may
be limited.

    Under various federal, state, and local environmental laws and regulations,
a current or previous owner, lessee or operator of real property may be liable
for the costs of removal or remediation of hazardous or toxic substances on,
under or in such property. These laws often impose liability whether or not the
owner, lessee or operator knew of or was responsible for the presence of such
hazardous or toxic substances. For example, liability may arise as a result of
the historical use of a site or from the migration of contamination from
adjacent or nearby properties. Any such contamination or liability may also
reduce the value of the property. Additionally, environmental laws govern the
removal, encapsulation or disturbance of asbestos-containing materials when
those materials are in poor condition or in the event of a building remodeling,
renovation or demolition. These laws and common law principles could be used to
impose liability for the release of asbestos-containing materials into the air,
and third parties may seek recovery from owners or operators of real properties
for personal injury

                                       26
<PAGE>
associated with exposure to such materials. In connection with the ownership,
lease or operation of hotels, including properties managed or franchised by
Hilton or Promus, Hilton may be potentially liable for any such costs. While we
are currently involved in several remedial projects, we are not currently aware
of any obligations to perform any remediation that will have a material adverse
effect on Hilton. We cannot assure you, however, that Hilton's or Promus'
properties have not been or will not be adversely affected by the historical or
current uses of such properties or the activities in the vicinity of such
properties or that the potential liability resulting from non-compliance or
other claims relating to environmental matters will not have a material adverse
effect on Hilton.

    HILTON'S BUSINESS WILL CONTINUE TO BE REGULATED

    The lodging industry is subject to federal, state and local government
regulations, including those relating to the preparation and sale of food and
beverages, such as health and liquor license laws, and building and zoning
requirements. Also, Hilton and its customers are subject to laws governing their
relationships with employees, including minimum wage requirements, overtime,
working conditions and work permit requirements. Hilton will also be subject to
federal regulations and state laws that govern the offer and sale of franchises,
including state laws that require approvals before franchises can be offered or
sold in that state. The failure to obtain or retain liquor licenses or approvals
to sell franchises, or an increase in the minimum wage rate, employee benefit
costs or other costs associated with employees, could harm Hilton.

    Under the Americans with Disabilities Act of 1990, all public accommodations
are required to meet federal requirements related to access and use by disabled
persons. We believe that the hotels that we own or that are under our management
are substantially in compliance with these requirements. However, a
determination that these hotels are not in compliance with the law could result
in the imposition of fines, an award of damages to private litigants or
significant expense to Hilton in bringing these hotels into compliance.


    Hilton operates a riverboat casino in Kansas City, Missouri, which it has
agreed to sell to a third party. Hilton also owns a 50% interest in the
consortium that operates the Casino Windsor in Windsor, Ontario, Canada. These
operations are subject to regulation by the Missouri Gaming Commission and the
Ontario Alcohol and Gaming Commission. These regulations are more fully
described in Hilton's filings with the SEC. For information on how you can
obtain copies of these filings, see "Where You Can Find More Information" on
page 94 of this joint proxy statement/prospectus.

                    THE MEETINGS--GENERAL PROXY INFORMATION

THE HILTON STOCKHOLDERS MEETING

    GENERAL; DATE, TIME AND PLACE OF THE SPECIAL MEETING


    Hilton's board of directors is sending this joint proxy statement/prospectus
to Hilton's stockholders in connection with the Hilton board's solicitation of
proxies for use at the special meeting of Hilton stockholders to be held on
November 30, 1999, at 10:00 a.m., local time, at:


       Hilton Beverly Hills
       9876 Wilshire Boulevard
       Beverly Hills, California 90210

    MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

    At the special meeting, Hilton stockholders will be asked:

    - to approve the merger agreement and the issuance of Hilton common stock in
      the acquisition.


    - to approve the amendment to Hilton's certificate of incorporation to
      increase the authorized number of shares of Hilton common stock from
      400 million shares to 500 million shares. This is designed to allow for
      future stock issuances by Hilton for purposes such as raising funds to
      repay debt, making acquisitions or granting employee incentives. Assuming
      that approximately 113 million shares are issued in the acquisition,
      Hilton would have approximately 368 million shares of common stock
      outstanding. If approved, the amendment to the certificate of
      incorporation will take effect only if the acquisition is completed.



    - to approve an amendment to Hilton's by-laws to change the authorized
      number of directors from the fixed number of 12 to a range of 10 to 20,
      with the exact number to be set from time to time by the board of
      directors. The amendment to Hilton's by-laws is designed to provide Hilton
      greater flexibility in the composition of its board of directors. If
      Hilton stockholders approve the amendment to the by-laws, Hilton intends
      to set the authorized number of directors at 14 and add to its board two
      new directors chosen from Promus' current board. If approved, the
      amendment to the bylaws will take effect regardless of the outcome of the
      votes on the acquisition and the amendment to Hilton's certificate of
      incorporation.



    - to transact other business that properly comes before the special meeting
      or any postponements or adjournments of the special meeting.


    APPROVAL OF THE MERGER AGREEMENT AND COMPLETION OF THE ACQUISITION ARE NOT
DEPENDENT ON APPROVAL OF THE PROPOSED AMENDMENTS TO THE HILTON CERTIFICATE OF
INCORPORATION AND BYLAWS.

    RECORD DATE FOR VOTING ON THE ACQUISITION; STOCKHOLDERS ENTITLED TO VOTE


    Only Hilton stockholders of record at the close of business on October 15,
1999 are entitled to notice of and to vote at the special meeting. As of the
close of business on that record date, there were 254,978,461 shares of Hilton
common stock outstanding and entitled to vote, which were held of record by
11,533 stockholders. Each Hilton stockholder is entitled to one vote for each
share of Hilton common stock held as of the record date.


    SECURITY OWNERSHIP


    Hilton's previous SEC filings contain information on the security ownership
of certain beneficial owners and the security ownership of management. For
information on how you may obtain copies of these filings, please see the
section entitled "Where You Can Find More Information" on page 94.


                                       28
<PAGE>
    VOTING AND REVOCATION OF PROXIES


    The proxy for the Hilton stockholders meeting is solicited on behalf of
Hilton's board of directors. Hilton stockholders are requested to complete, date
and sign the Hilton proxy and promptly return it in the accompanying envelope or
otherwise mail it to Hilton. All properly executed proxies received by Hilton
before the special meeting that are not revoked will be voted at the special
meeting in accordance with the instructions indicated on the proxies or, if no
direction is indicated, to approve the merger agreement and the issuance of
Hilton common stock in the acquisition and the amendments to Hilton's
certificate of incorporation and by-laws. Hilton stockholders may also vote by
calling the toll-free telephone number on the proxy card and following the
instructions on the proxy card.


    A Hilton stockholder that has given a proxy may revoke it at any time before
it is exercised at the special meeting by doing any of the following:

    - delivering to the Secretary of Hilton a written notice, bearing a date
      later than the date of the proxy, stating that the proxy is revoked;

    - signing and delivering a proxy relating to the same shares and bearing a
      later date than the date of the previous proxy, or submitting a telephonic
      proxy at a later date, before the vote at the special meeting; or

    - attending the special meeting and voting in person.

    PROXY SOLICITATION

    In addition to this mailing, Hilton employees may solicit proxies
personally, electronically or by telephone. Hilton is also paying D. F. King &
Co. a fee of $13,500 plus expenses to help with the solicitation.

    STOCKHOLDER VOTE REQUIRED FOR HILTON PROPOSALS

    Hilton stockholders' approval of the merger agreement and the issuance of
Hilton common stock in the acquisition requires the affirmative vote of the
holders of a majority of the shares of Hilton common stock represented at the
special meeting. Hilton stockholders' approval of the amendment to Hilton's
certificate of incorporation requires the affirmative vote of the holders of a
majority of the outstanding shares of Hilton common stock. Hilton stockholders'
approval of the amendment to the by-laws requires the affirmative vote of the
holders of 75% of the outstanding shares of Hilton common stock.


    Abstentions and broker non-votes are not counted as voting with respect to
the approval of the merger agreement and the issuance of shares and will have no
effect on this vote. Abstentions and broker non-votes are not counted as
affirmative votes with respect to the proposed amendment to Hilton's certificate
of incorporation and will have the same effect as votes against approval of the
amendment. Abstentions are not counted as affirmative votes with respect to the
proposed amendment to Hilton's by-laws and will have the same effect as votes
against approval of the amendment.



    In addition, the required vote of the Hilton stockholders with respect to
the proposed amendments to the certificate of incorporation and the by-laws is
based upon the number of outstanding shares of Hilton common stock rather than
upon the shares actually voted in person or by proxy at the special meeting.
Therefore, if a stockholder fails either to submit a proxy or to vote in person
at the special meeting, it will have the same effect as a vote against approval
of the amendments.

    RECORD DATE FOR VOTING ON THE ACQUISITION; STOCKHOLDERS ENTITLED TO VOTE


    Only Promus stockholders of record at the close of business on October 15,
1999 are entitled to notice of and to vote at the special meeting. As of the
close of business on that record date, there were 78,692,352 shares of Promus

    A Promus stockholder that has given a proxy may revoke it at any time before
it is exercised at the special meeting by doing any of the following:

    - delivering to the Secretary of Promus a written notice, bearing a date
      later than the date of the proxy, stating that the proxy is revoked;

    PROXY SOLICITATION


    In addition to this mailing, Promus employees may solicit proxies
personally, electronically or by telephone. Morrow & Co., Inc. has also been
engaged to assist with proxy solicitation. Morrow & Co., Inc. was previously
engaged by Promus to perform strategic consulting, stock watch/nominee
identification and related consulting services for a fee of $125,000.
Subsequently, Morrow & Co., Inc. agreed to perform proxy solicitation services
at no additional charge other than reimbursement of out-of-pocket expenses.


    STOCKHOLDER VOTE REQUIRED TO APPROVE THE ACQUISITION


    Promus stockholders' approval of the acquisition requires the affirmative
vote of the holders of a majority of the outstanding shares of Promus common
stock. Abstentions and broker non-votes are not affirmative votes and will have
the same effect as votes against approval of the acquisition. IN ADDITION, THE
REQUIRED VOTE OF THE PROMUS STOCKHOLDERS IS BASED UPON THE NUMBER OF OUTSTANDING
SHARES OF PROMUS COMMON STOCK RATHER THAN UPON THE SHARES ACTUALLY VOTED IN
PERSON OR BY PROXY AT THE SPECIAL MEETING. THEREFORE, IF A STOCKHOLDER FAILS
EITHER TO SUBMIT A PROXY OR TO VOTE IN PERSON AT THE SPECIAL MEETING, IT WILL
HAVE THE SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE ACQUISITION.

of consideration to be received should hold their stock certificates until after
the closing, when they will receive a letter of transmittal instructing them on
how to exchange their certificates for acquisition consideration. For more
information regarding the procedures for completing the forms of election and
exchanging Promus stock certificates for Hilton stock certificates, please see
the section entitled "The Merger Agreement--Election and Proration" on page 68.

                                THE ACQUISITION


GENERAL


    Each of our boards of directors has approved the merger agreement, which
provides for an acquisition of Promus by Hilton. As a result of the acquisition,
Promus stockholders will receive in the aggregate for their shares
approximately:


    - $1.66 billion in cash; and



    - 113 million shares of Hilton common stock; this number of shares is based
      on what the exchange ratio would be if the average Hilton stock price were
      $9.00, which was the closing price on October 18, 1999.


BACKGROUND OF THE ACQUISITION


    Hilton has from time to time considered expanding its operations through
acquisitions of other lodging companies, including Promus. On April 14, 1999,
Stephen Bollenbach, Hilton's President and Chief Executive Officer, and Matthew
Hart, Hilton's Executive Vice President, Chief Financial Officer and Treasurer,
met at Hilton's initiative with Norman Blake, Promus' Chairman, President and
Chief Executive Officer, and Dan Hale, Promus' Executive Vice President and
Chief Financial Officer. The Hilton representatives expressed an interest in
exploring a business combination of the two companies. Mr. Blake indicated that
Promus was not interested in pursuing a transaction, and no further contact
occurred between Hilton and Promus until July 1999.


    On May 25, 1999, Promus announced that it had lowered its earnings
expectation for 1999 as a result of softening market conditions, costs to be
incurred as a result of repositioning both the Doubletree and Red Lion brands
and deteriorating performance of Doubletree and Red Lion hotels. Promus' stock
price declined from $30.50 on May 24 to a low of $23.75 on June 2, 1999.

    In light of the Promus announcement, Hilton again reviewed a possible
acquisition of Promus. From July 6, 1999 to July 15, 1999, Hilton acquired
500,000 shares of Promus common stock in the open market, for a total price of
approximately $14.2 million.

    Hilton sent a letter dated July 16, 1999 to Mr. Blake, in which Hilton
discussed a potential acquisition of Promus. The proposed purchase price was
$37.00 per share, which was a 32% premium over the closing price of Promus stock
on July 15, 1999. Hilton proposed paying for the acquisition with 50% cash and
50% Hilton stock. On July 19, 1999, Mr. Blake informed Mr. Bollenbach that a
Promus board meeting was scheduled for July 29 and 30, 1999, and that the Hilton
proposal would be reviewed with the Promus board at that meeting in conjunction
with the already scheduled presentations of Promus's new operating and strategic
plan. Mr. Blake informed the Promus board of the Hilton proposal at a special
meeting held on July 20, 1999.

    On July 29, the Promus board of directors held a regular meeting at which,
among other things, the Promus board received a presentation from management
regarding a new operating and strategic plan for Promus. The Promus board of
directors met again the following day to continue discussions about the
strategic plan and also to discuss the proposal outlined in Hilton's July 16th
letter. At that meeting, the Promus board of directors determined not to proceed
with Hilton's proposal and instructed Promus management to explore Promus'
strategic alternatives, including remaining independent and third party
transactions that might further Promus' strategic goals and the interests of
Promus and its stockholders.

    On August 2, 1999, Mr. Blake called Mr. Bollenbach and said that Hilton's
proposal had been rejected by the Promus board. Later that day, Hilton faxed a
letter to Promus indicating that Hilton intended to issue a press release
regarding Hilton's recent acquisition of Promus shares, Hilton's intent

                                       32
<PAGE>
to buy more shares and its interest in Promus. After discussion between
Mr. Bollenbach and Mr. Blake, Hilton agreed not to issue the proposed press
release at that time.

    During the week of August 2nd, Promus management and Salomon Smith Barney,
Promus' financial advisor, contacted a number of companies in the hotel industry
to gauge their interest in a business combination or other strategic transaction
with Promus. The following week, Promus signed confidentiality agreements with
several of these parties and began discussions concerning potential
transactions.

    On August 9, Mr. Blake and Mr. Bollenbach met in Houston, Texas. At the
meeting, Mr. Bollenbach and Mr. Blake discussed the strategic fit and potential
synergies between Hilton and Promus, as well as a possible acquisition of Promus
by Hilton. Mr. Bollenbach gave Mr. Blake a draft form of merger agreement that
Hilton believed was appropriate for the proposed transaction. Mr. Blake informed
Mr. Bollenbach that the Promus board of directors had instructed Promus
management to explore Promus' strategic alternatives, including remaining
independent and third party transactions, and that, as part of this strategic
review, Promus would be willing to consider any proposal from Hilton that was
superior to the proposal in Hilton's July 16th letter. Mr. Blake invited Hilton
to participate in a series of due diligence meetings with Promus management,
similar to meetings being held with other parties.

    Hilton responded that it was not interested in pursuing a transaction under
circumstances involving the solicitation of interest of other parties because
Hilton believed that such a process inevitably would become public and risk
significant damage to the business and value of Promus.


    At a special meeting of the Promus board of directors on August 13, Promus
management and Salomon Smith Barney apprised the Promus board of Mr. Blake's
conversations with Mr. Bollenbach and the contents of a letter from Hilton dated
August 11 indicating that Hilton would withdraw its proposal effective
August 16 if Promus' process with third parties continued. Promus management and
Salomon Smith Barney also reported on the status of discussions with other
parties. The Promus board of directors authorized management to continue with
its review of Promus' strategic alternatives, including possible further
discussions with Hilton. On August 16, 1999, Hilton's July 16, 1999 proposal was
withdrawn.


    During the week of August 16th, Promus management met with, and provided
information about Promus to, the third parties that had executed confidentiality
agreements. These parties were asked to present preliminary indications of
interest and value ranges as promptly as practicable.


    At a special meeting of the Promus board of directors on August 23, Promus
management and Salomon Smith Barney updated the Promus board on the status of
their discussions with the other parties. The Promus board of directors
authorized management and Salomon Smith Barney to continue these discussions and
also to initiate negotiations with Hilton.


    Between August 17 and August 24, 1999, financial advisors representing
Hilton and Promus had various discussions in anticipation of a potential meeting
between the parties. On August 25, 1999, a confidentiality agreement was
executed by the parties. On August 26, 1999, Mr. Bollenbach, Mr. Blake and
others from Promus and Hilton and their advisors met in Denver, Colorado to
discuss an acquisition. At this meeting, Promus' representatives urged Hilton to
make its best offer. In response, Hilton proposed a per share purchase price of
$38.50, with the total consideration consisting of 55% cash and 45% stock,
including a "collar" centered on the Hilton stock price, and the cash-out of
outstanding Promus stock options. Mr. Blake stated that he would present this
proposal to the Promus board of directors and would communicate Promus' response
to Mr. Bollenbach. Subject to approval by the Promus board of directors, the
parties scheduled negotiating and diligence sessions for the following week.

    At a special meeting of the Promus board of directors on August 27, Promus
management and Salomon Smith Barney informed the Promus board about the meeting
with Hilton and the status of the discussions with other parties. Based on this
report, the Promus board of directors decided that no other third party had
proposed a transaction that was as favorable to Promus stockholders as the
Hilton proposal. The Promus board of directors authorized Promus management to
proceed with further discussions with Hilton to determine whether a definitive
agreement could be reached.

    During the week of August 30, 1999, Hilton and Promus, together with their
legal and financial advisors, met in New York to conduct due diligence and to
negotiate the terms of the merger agreement. Negotiations continued throughout
the week.

    On September 1, in response to press reports about a possible transaction
between Hilton and Promus, Hilton and Promus each issued statements confirming
that discussions were taking place.

    On September 3, 1999, the boards of directors of Hilton and Promus met
separately to consider the proposed transaction. At the Hilton board meeting,
senior management and Hilton's financial and legal advisors discussed the
following with the board:

    - the status of the negotiations with respect to the proposed transaction;

    - the potential benefits and risks associated with an acquisition of Promus;
      and

    - the principal terms and conditions of the merger agreement.

    Hilton's financial advisors reviewed the strategic rationale for, and
financial analyses relating to, the acquisition. Morgan Stanley delivered its
oral opinion to the Hilton board, which was subsequently confirmed in writing,
that, as of such date and based upon and subject to the matters stated in the
opinion, the proposed consideration to be paid pursuant to the merger agreement
was fair to Hilton from a financial point of view. In addition, DLJ delivered
its oral opinion to the Hilton board, which was subsequently confirmed in
writing, that, as of such date and based upon and subject to the matters stated
in the opinion, the proposed transaction was fair to Hilton and its stockholders
from a financial point of view.


    The Hilton board then discussed the terms of the proposed acquisition and
the analyses presented by the financial advisors, unanimously approved the
acquisition, and authorized management to finalize the terms of the merger
agreement.



    At the Promus board meeting, the Promus board received presentations from
Promus management, Salomon Smith Barney and Davis Polk & Wardwell, the law firm
engaged to represent Promus, regarding the terms and conditions of the proposed
merger agreement. As part of its financial presentation to the Promus board,
Salomon Smith Barney delivered its oral opinion to the Promus board, which was
subsequently confirmed in writing, that, as of such date and based upon and
subject to the matters stated in the opinion, the consideration to be received
in the acquisition by Promus stockholders was fair from a financial point of
view to Promus stockholders. After discussion and due consideration, the Promus
board of directors unanimously approved the acquisition and authorized
management to finalize the terms of the merger agreement.


    The acquisition was jointly announced by Hilton and Promus on the morning of
September 7.

REASONS FOR THE ACQUISITION

    HILTON'S REASONS FOR THE ACQUISITION

    Hilton's board of directors believes that the acquisition will benefit
Hilton and its stockholders for the following reasons:

    - ENHANCED COMPETITIVE POSITION. The acquisition will enhance Hilton's
      competitive position as a multi-branded owner, operator, manager and
      franchisor of hotels, comparable in size to its principal competitors in
      terms of number of properties, market segments served and profitability.

    - INCREASE REVENUES FROM MANAGEMENT AND FRANCHISING. Due to the number of
      Promus' management and franchise properties, the acquisition will increase
      Hilton's revenues from fees relating to management, franchising,
      purchasing and other services from approximately 13% of total revenues to
      approximately 30% of total revenues. This addition to Hilton's portfolio
      will create a more diversified and balanced income stream.


    - COMPLEMENTARY PORTFOLIO OF HOTEL BRANDS AND GEOGRAPHIC
      DIVERSIFICATION. Upon completion of the acquisition, Hilton will offer
      brands in most industry categories, including upscale to mid-priced
      products in the full service, all suite, extended stay and limited service
      segments, as well as vacation ownership. Doubletree will serve as a
      complementary brand to Hilton's full service product. Promus' Embassy
      Suites and Homewood Suites will expand Hilton's offerings in the all-
      suites and extended stay segments of the market, while Hampton Inns will
      give Hilton a stronger presence in the limited service segment. The
      addition of the Promus' properties will also diversify Hilton's
      geographical asset concentration and expand its presence throughout the
      United States.



    - SYNERGIES AND ECONOMIES OF SCALE. Hilton believes that the acquisition
      will result in significant synergies and revenue enhancements from
      consolidating corporate functions and regional offices by combining
      strengths in all core functional areas such as finance, legal, human
      resources, operations, technology and development. In addition, Hilton
      believes that the acquisition will result in significant economies of
      scale in such areas as marketing and purchasing. By way of example, Hilton
      believes that the acquisition will result in economies of scale by:



       -- providing greater opportunity for expansion with multiple brands and
          market segments, including growing the Embassy Suites and Hampton Inns
          brands and extended stay product, and growing and maintaining
          Doubletree as a complementary brand to Hilton;


       -- blending both companies' products in the extended-stay, conference
          hotel and time-share markets;

       -- including the Promus brands in Hilton's award-winning HHonors frequent
          guest program and its central reservation system, Hilton Reservations
          Worldwide, as well as Hilton's international sales organization,
          consisting of 39 sales offices worldwide, Hilton.com and Hilton
          Direct, Hilton's group business booking operation; and

       -- spreading fixed overhead expense across a wider base of properties.

    Hilton's board of directors consulted with Hilton's senior management, as
well as its legal and financial advisers, in reaching its decision to approve
the acquisition. Among the factors considered by Hilton's board in its
deliberations were the following:

    - historical information concerning Hilton's and Promus' financial
      performance, results of operations, assets, liabilities, operations, brand
      development, management and competitive position;

                                       35
<PAGE>
    - management's view of the financial condition, results of operations,
      assets, liabilities, businesses and prospects of Hilton and Promus after
      giving effect to the acquisition;

    - current market conditions and historical trading information with respect
      to Hilton and Promus common stock;

    - comparable merger transactions in the lodging industry;


    - the terms and conditions of the merger agreement, including closing
      conditions, termination fees and no solicitation provisions;



    - the analysis prepared by Morgan Stanley and presented to Hilton's board of
      directors and the oral opinion of Morgan Stanley, subsequently confirmed
      in writing, that the consideration to be paid by Hilton pursuant to the
      merger agreement was fair, from a financial point of view, to Hilton as
      described more fully in the text of the entire opinion attached as
      Appendix B to this joint proxy statement/prospectus; and


    - the analysis prepared by DLJ and presented to Hilton's board of directors
      and the oral opinion of DLJ, subsequently confirmed in writing, that the
      consideration to be paid by Hilton in the acquisition was fair, from a
      financial point of view, to Hilton and its stockholders, as described more
      fully in the text of the entire opinion attached as Appendix C to this
      joint proxy statement/ prospectus.


    Hilton's board of directors does not intend the discussion of information
and factors to be exhaustive, but believes the discussion to include all of the
material factors that it considered. In view of the complexity and wide variety
of information and factors that it considered, Hilton's board did not find it
practical to quantify or otherwise assign relative or specific weights to the
factors considered. However, after taking into consideration all of the factors
discussed above, Hilton's board concluded that the merger agreement and
acquisition were fair to, and in the best interests of, Hilton and its
stockholders and that Hilton should proceed with the acquisition.


    PROMUS' REASONS FOR THE ACQUISITION


    At its September 3, 1999 meeting, the Promus board of directors unanimously
determined that the acquisition is fair to and in the best interests of Promus
and Promus' stockholders. Accordingly, the Promus board of directors has
unanimously approved the merger agreement and recommends that Promus'
stockholders vote "FOR" approval of the merger agreement and the acquisition.



    In the course of reaching its decision to adopt the merger agreement, the
Promus board of directors consulted with Promus' management, as well as its
outside legal counsel and its financial advisor, and considered a number of
factors, including:


       - the Promus board's view of the need to reposition the business and
         brand portfolio of Promus in order to sustain and drive long-term
         growth, and the significant short- and medium-term costs associated
         with executing such a long-term strategic plan as an independent entity
         and the risks associated with implementation of such plan, balanced
         against the possible long-term benefits that would result from
         execution of such plan;

       - a review of the feasibility of other possible strategic alternatives to
         the acquisition, including the fact that, notwithstanding an
         investigation of potential third-party interest conducted by management
         and Salomon Smith Barney, no other third party proposed a transaction
         that was as favorable to Promus stockholders as the acquisition;

       - current industry, economic and market conditions, including softening
         in the market segments in which Promus operates and the risks to Promus
         associated with remaining independent amidst industry-wide
         consolidation;

                                       36
<PAGE>
       - the presentations made by Salomon Smith Barney to the Promus board of
         directors, and Salomon Smith Barney's opinion to the effect that, as of
         September 3, 1999, the acquisition consideration was fair, from a
         financial point of view, to Promus' stockholders;

       - the fact that Promus stockholders may elect to receive the acquisition
         consideration in the form of cash or Hilton stock, subject to
         proration;


       - the fact that the value of the stock portion of the acquisition
         consideration is not fixed if the average Hilton stock price prior to
         the closing (calculated as described under "The Merger
         Agreement--Consideration to be Received for Promus Common Stock in the
         Acquisition" on page 69) is below $11.97 or above $13.23, and that the
         closing price of the Hilton stock on September 2, 1999 was below
         $11.97;



       - the fact that if the average Hilton stock price prior to the closing is
         below $11.97, Promus stockholders would receive 3.2158 shares of Hilton
         stock for each Promus share, but if the average Hilton stock price
         prior to the closing is above $13.23, Promus stockholders would receive
         2.9096 shares of Hilton stock, and accordingly share in any
         appreciation or depreciation in the Hilton stock prior to the closing;



       - the historical trading prices of the Promus stock and the fact that an
         acquisition consideration of $38.50 represented a premium of
         approximately



           -- 32.5% over the closing price of Promus stock on August 31, 1999,
              the date prior to announcement that Hilton and Promus were in
              discussions regarding a possible transaction, and


           -- 21.5% over the closing price of Promus stock on September 2, 1999,
              the date prior to the Promus board meeting;


       - the potential for appreciation and the risk of depreciation in value of
         the Hilton stock as a result of the acquisition or for other reasons,
         and the ability of Promus stockholders to have a significant equity
         participation in the combined company through ownership of
         approximately 30% of the outstanding stock of the combined company
         after the acquisition;

       - the strategic benefits of a combination with Hilton, including:

           -- the global nature of Hilton's brand which could provide
              overarching support for market awareness of Promus' brands,

           -- Hilton's strong national sales force and international market
              access which could enhance group business,

           -- Hilton's established customer loyalty/frequency program which
              could increase property-level revenues,

           -- Promus' franchising expertise which could add incremental growth
              to Hilton's brands,

           -- the opportunity to extend Hampton Inn, Hampton Inn & Suites and
              Homewood Suites development and franchising in the western part of
              the U.S. by leveraging Hilton's regional presence, and


           -- the opportunity for near- and longer-term synergies resulting from
              the combination;


       - the fact that after the acquisition the combined company would be
         significantly more leveraged on a relative basis than Promus, the
         possible implications of such increased leverage on the credit rating
         of the long term debt of the combined company and the associated risks,
         including increased interest costs under Hilton's outstanding debt;


       - the risks and difficulties of integrating the two companies, and other
         risks of the transaction and to the business, as more fully described
         under "Risk Factors," on page 23;


                                       37
<PAGE>

       - an evaluation of the likelihood that the acquisition would be
         consummated, including the terms and conditions of the financing
         commitment that Hilton has obtained to fund the cash portion of the
         consideration and the fact that the availability of such funds is
         (except in circumstances of material breach of representations,
         warranties, covenants or agreements or material failure by Hilton to
         take any action necessary under any financing agreements) a condition
         to Hilton's obligation to consummate the acquisition, and the
         circumstances under which Hilton's failure to obtain financing could
         result in a payment of $150 million to Promus;



       - the intention of the parties that the acquisition be treated as a
         tax-free reorganization for U.S. federal income tax purposes, such that
         Promus stockholders would be taxed on any gain realized only to the
         extent of cash consideration received by them, the circumstances under
         which the acquisition would not be so treated and the likelihood or
         unlikelihood of such circumstances developing;



       - that if the fair market value for tax purposes of all shares of Hilton
         stock to be delivered in connection with the acquisition is less than
         40% of the sum of the total consideration paid in connection with the
         acquisition or if the opinions as to the tax-free nature of the
         transaction could not otherwise be delivered, the acquisition would not
         constitute a tax-free reorganization for U.S. federal income tax
         purposes and the Promus stockholders would be taxed on any gain
         realized regardless of the form of consideration received by them;



       - the terms and conditions of the merger agreement, including the
         provisions that permit Promus to furnish information to and participate
         in discussions or negotiations with a third party if the Promus board
         of directors determines in good faith that such third party has
         presented an acquisition proposal that could reasonably be expected to
         constitute a superior proposal, as described under "The Merger
         Agreement--No Solicitation; Covenant to Recommend," on page 77, and to
         terminate the merger agreement to accept such superior proposal upon
         prior notice to Hilton and payment of a $75 million termination fee;


       - that two of the Promus board members would become directors of Hilton;
         and


       - the interests that certain executive officers and directors of Promus
         may have with respect to the acquisition in addition to their interests
         as stockholders of Promus generally. See "Interests of Certain Persons
         in the Acquisition" on page 56.



    In view of the wide variety of factors considered in connection with its
evaluation of the acquisition and the complexity of these matters, the Promus
board of directors did not find it useful to and did not attempt to quantify,
rank or otherwise assign relative weights to these factors. The Promus board
relied on the experience and expertise of Salomon Smith Barney, its financial
advisor, for quantitative analysis of the financial terms of the acquisition.
See "Opinions of Financial Advisors--Opinion of Salomon Smith Barney Inc." on
page 51. In addition, the Promus board did not undertake to make any specific
determination as to whether any particular factor, or any aspect of any
particular factor, was favorable or unfavorable to the Promus board's ultimate
determination, but rather the Promus board conducted an overall analysis of the
factors described above, including through discussions with and questioning of
Promus' management and legal and financial advisors. In considering the factors
described above, individual members of the Promus board of directors may have
given different weight to different factors.


OPINIONS OF HILTON FINANCIAL ADVISORS

    OPINION OF MORGAN STANLEY & CO. INCORPORATED

    In a letter agreement dated August 11, 1999, Hilton retained Morgan Stanley
to render a financial opinion in connection with the acquisition, based on
Morgan Stanley's qualifications, expertise and

                                       38
<PAGE>
reputation. On September 3, 1999, Morgan Stanley delivered an oral opinion,
subsequently confirmed in writing on September 7, 1999, to the effect that,
based upon and subject to the considerations set forth in the opinion, the
consideration to be paid by Hilton pursuant to the merger agreement is fair from
a financial point of view to Hilton.

    THE FULL TEXT OF MORGAN STANLEY'S WRITTEN OPINION, DATED AS OF SEPTEMBER 7,
1999, WHICH SETS FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, PROCEDURES
FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS
ATTACHED AS APPENDIX B TO THIS JOINT PROXY STATEMENT/PROSPECTUS. HILTON'S
STOCKHOLDERS ARE URGED TO, AND SHOULD, READ THE OPINION CAREFULLY AND IN ITS
ENTIRETY. MORGAN STANLEY'S OPINION IS DIRECTED TO HILTON'S BOARD OF DIRECTORS,
ADDRESSES ONLY THE FAIRNESS OF THE CONSIDERATION TO BE PAID BY HILTON FROM A
FINANCIAL POINT OF VIEW, AND DOES NOT ADDRESS ANY OTHER ASPECT OF THE
ACQUISITION OR CONSTITUTE A RECOMMENDATION TO ANY HILTON STOCKHOLDER AS TO HOW
TO VOTE AT THE SPECIAL MEETING. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.

    In connection with rendering its opinion, Morgan Stanley, among other
things:

    - reviewed certain publicly available financial statements and other
      information of Promus and Hilton;

    - reviewed certain internal financial statements and other financial and
      operating data concerning Promus prepared by the management of Promus;

    - reviewed certain financial projections prepared by the management of
      Promus;

    - discussed the past and current operations and financial condition and the
      prospects of Promus, including information relating to certain strategic,
      financial and operational benefits anticipated from the acquisition, with
      senior executives of Promus;

      and Hilton common stock;

    - compared the financial performance of Promus and the prices and trading
      activity of Promus common stock with those of certain other comparable
      publicly traded companies and their securities;

    - compared the financial performance of Hilton and the prices and trading
      activity of Hilton common stock with those of certain other comparable
      publicly traded companies and their securities;

    - reviewed the financial terms, to the extent publicly available, of certain

                                       39
<PAGE>
    - participated in discussions and negotiations among representatives of
      Promus and Hilton and their financial and legal advisors;

    - reviewed a draft of the merger agreement and certain related documents;
      and

    - performed such other analyses and considered such other factors as Morgan
      Stanley deemed appropriate.

    Morgan Stanley assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by it for the purposes of
its opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the acquisition, Morgan Stanley assumed that they had been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the future financial performance of Promus and Hilton. Morgan
Stanley has also relied upon, without independent verification, the assessment
of Hilton of the strategic, financial and operational benefits expected to
result from the acquisition. In addition, Morgan Stanley has assumed that the
acquisition will be consummated in accordance with the terms set forth in the
merger agreement. Morgan Stanley has not made any independent valuation or
appraisal of the assets or liabilities of Promus, nor was Morgan Stanley
furnished with any such appraisals. Morgan Stanley's opinion is necessarily
based on financial, economic, market and other conditions as in effect on, and
the information made available to it as of, September 7, 1999.

    The following is a summary of certain analyses performed by Morgan Stanley
in connection with its oral opinion and the preparation of its written opinion
letter dated September 7, 1999. These summaries of financial analyses include
information presented in tabular format. In order to fully understand the
financial analyses used by Morgan Stanley, the tables must be read together with
the text of each summary. The tables alone do not constitute a complete
description of the financial analyses.

    HISTORICAL STOCK PRICE TRADING ANALYSIS.  Using the closing price for
Hilton's and Promus' common stock on the NYSE, Morgan Stanley reviewed the
closing prices over a 12-month period ending August 31, 1999. Morgan Stanley
noted that the trading range per share for Hilton over the period examined was
between a low of $12.06 and a high of $16.82. Morgan Stanley noted that the
trading range per share for Promus over the period examined was between a low of
$20.50 and a high of $38.50.

    PROMUS COMPARABLE COMPANY ANALYSIS.  Using publicly available information,
Morgan Stanley performed an analysis comparing Promus' current trading value and
the implied multiples for a variety of operating statistics to those of selected
publicly traded companies that share some of the same characteristics of Promus.
In particular, Morgan Stanley focused on the following companies:

    - Choice Hotels International, Inc.

    - Hilton

    - Marriott International, Inc.

    - Starwood Hotels & Resorts Worldwide, Inc.

    - Wyndham International Inc.

    Morgan Stanley reviewed financial information including the price to
forecasted calendar year 1999 and calendar year 2000 earnings multiples and the
aggregate value to forecasted calendar year 1999 and 2000 earnings before
interest, taxes, depreciation and amortization ("EBITDA") multiples. The

                                       40

financial information was based on a compilation of earnings projections by
securities research analysts. The tables below summarize these analyses and the
relevant statistics for Promus as of August 31, 1999.

    Morgan Stanley applied these multiples from the comparable companies to
Promus' corresponding financial statistics to arrive at a range of per share
equity values for Promus. Using this methodology, Morgan Stanley observed that,
assuming a 25% - 35% control premium, the implied value per share of Promus
common stock ranged from $38.08 to $54.39. Morgan Stanley noted that the
acquisition consideration based on the merger agreement was $38.50 per share. No
company considered in the foregoing analysis is identical to Promus. In
evaluating comparable companies, Morgan Stanley made judgments and assumptions
with regard to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Hilton and Promus, such as the impact of competition on Promus and the industry
generally, industry growth and the absence of any adverse material change in the
financial condition and prospects of Promus or the industry or in the financial
markets in general. Mathematical analysis (such as determining the average or
median) is not in itself a meaningful method of using comparable company data.

    PROMUS SELECTED TRANSACTION ANALYSIS.  Using publicly available information,
Morgan Stanley examined the terms of certain transactions involving acquisitions
of companies in businesses that were similar in some characteristics to the
business of Promus. These transactions included the following transactions:

Doubletree Corporation.........................  Promus
Wyndham International, Inc.....................  Patriot American Hospitality, Inc.
Renaissance Hotel Group N.V....................  Marriott International, Inc.
Red Lion Hotels, Inc...........................  Doubletree Corporation
</TABLE>

    Based on this review, Morgan Stanley selected a range of 10.0-12.0 times
next 12 months EBITDA for the purposes of determining a valuation. Applying this
range to Promus' next 12 months EBITDA produced an implied value per share of
Promus common stock between $45.54 and $56.91. Morgan

                                       41
<PAGE>
Stanley also analyzed each of the above transactions to determine the premium
offered by the acquiror to the acquiree's stockholders one month before the
announcement of the transaction. Based on this analysis, Morgan Stanley selected
a range of premiums of 25% to 35% for purposes of determining a valuation.
Applying this range to the average closing price for Promus, measured from 90 to
30 days before August 31, 1999, produced an implied value per share of Promus
common stock between $36.06 and $38.95.

    No transaction utilized in the analysis of selected precedent transactions
is identical to the acquisition in timing and size, and, accordingly, an
analysis of the results of the foregoing necessarily involves complex
considerations and judgments concerning financial and operating characteristics
of Promus and other factors that would affect the acquisition value of companies
to which it is being compared. In evaluating the precedent transactions, Morgan
Stanley made judgments and assumptions with regard to industry performance,
general business, economic, market and financial conditions and other matters,
many of which are beyond the control of Hilton and Promus, such as the impact of
competition on Promus and the industry generally, industry growth and the
absence of any adverse material change in the financial condition and prospects
of Promus or the industry or in the financial markets in general. Mathematical
analysis (such as determining the average or median) is not in itself a
meaningful method of using selected transaction data.

    PROMUS SUM OF THE PARTS ANALYSIS.  Morgan Stanley performed an analysis of
Promus assuming separation of Promus into its material components based on its
operating units.

    Morgan Stanley compared financial information of each operating unit with
publicly available information in the lodging industry. For this analysis,
Morgan Stanley examined a range of estimates based on securities research
analysts. The following table presents, as of August 31, 1999, the low and high
for the operating units of the estimated aggregate value to projected calendar
year 1999 EBITDA multiples based on the relevant lodging industry information:

    Morgan Stanley applied these multiples to Promus' corresponding financial
statistics, and using publicly available data for the value of Promus
outstanding debt, general and administrative expenses, land and other
investments, Morgan Stanley arrived at a range of per share equity values for
Promus of $40.85 to $46.35. In evaluating selected multiples, Morgan Stanley
made judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of Hilton and Promus, such as the impact of
competition on Promus and the industry generally, industry growth and the
absence of any adverse material change in the financial condition and prospects
of Promus or the industry or in the financial markets in general. Mathematical

    PROMUS DISCOUNTED CASH FLOW ANALYSIS.  Morgan Stanley performed a discounted
cash flow analysis for Promus based upon publicly available information, equity
research estimates and financial projections provided by the management of
Hilton, the "base case." Morgan Stanley calculated unlevered free cash flows,
defined as net income plus the aggregate of depreciation and amortization, other
non-cash expenses and after-tax interest expense less the sum of capital
expenditures and investment in non-cash working capital.

    Morgan Stanley calculated terminal values by applying a range of multiples
from 8.5x to 9.5x to last 12 months EBITDA. The cash flow streams and terminal
values were then discounted to the present using an estimated range of the
weighted average cost of capital for Promus of 11.5% to 12.5%. Morgan Stanley
performed its analysis both including and excluding assumed operational benefits
from the transaction prepared by the management of Hilton. The results of this
analysis as of August 31, 1999 are summarized in the table below.

    HILTON COMPARABLE COMPANY ANALYSIS.  Using publicly available information,
Morgan Stanley performed an analysis comparing Hilton's current trading value
and the implied multiples for a variety of operating statistics, both historical
and projected, to those of selected publicly traded companies that share some of
the same characteristics of Hilton. In particular, Morgan Stanley focused on the
following companies:

    - Marriott International, Inc.

    - Promus

    - Starwood Hotels & Resorts Worldwide, Inc.

    - Wyndham International, Inc.

    Morgan Stanley reviewed financial information including the price to
forecasted calendar year 1999 and calendar year 2000 earnings multiples and
aggregate value to forecasted calendar year 1999 and calendar year 2000 EBITDA
multiples. The financial information was based on a compilation of earnings

    PRO FORMA ANALYSIS OF THE ACQUISITION.  Morgan Stanley analyzed the pro
forma impact of the acquisition on Hilton's earnings per share ("EPS") and cash
EPS, defined as the sum of EPS and annual goodwill amortization per share. The
analysis was performed utilizing estimates for Hilton and Promus and
incorporated assumed operational benefits anticipated from the acquisition
prepared by the management of Hilton. Based on these forecasts and assuming
Hilton's share price of $12.65 and the achievement of the assumed benefits,
while the acquisition is not expected to be accretive to Hilton's EPS in 2000,
the acquisition is expected to be accretive to Hilton's cash EPS in 2000.

    In connection with the review of the acquisition by Hilton's board of
directors, Morgan Stanley performed a variety of financial and comparative
analyses for purposes of its opinion given in connection therewith. The
preparation of a fairness opinion is a complex process and is not necessarily
susceptible to a partial analysis or summary description. In arriving at its
opinion, Morgan Stanley considered the results of all of its analyses as a whole
and did not attribute any particular weight to any analysis or factor considered
by it. Morgan Stanley believes that the summary set forth and the analyses
described above must be considered as a whole and that selecting portions
thereof, without considering all its analyses, would create an incomplete view
of the process underlying its analyses and opinion. In addition, Morgan Stanley
may have given various analyses and factors more or less weight than other
analyses and factors and may have deemed various assumptions more or less
probable than other assumptions, so that the range of valuations resulting from
any particular analysis described above should therefore not be taken to be
Morgan Stanley's view of the actual value of Hilton or Promus.

    In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Hilton or Promus. Any
estimates contained in Morgan Stanley's analysis are not necessarily indicative
of future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates. The analyses performed were
prepared solely as a part of Morgan Stanley's analysis of the fairness from a
financial point of view to Hilton of the consideration to be paid pursuant to
the merger agreement and were conducted in connection with the delivery of
Morgan Stanley's opinion dated September 7, 1999 to Hilton's board of directors.
Morgan Stanley's analyses do not purport to be appraisals or to reflect the
prices at which shares of Promus' or Hilton's common stock might actually trade.
The consideration to be paid pursuant to the merger agreement was determined
through arm's length negotiations between Hilton and Promus and was approved by
Hilton's board of directors. Morgan Stanley did not recommend any specific
consideration to Hilton or that any specific consideration constituted the only
appropriate consideration for the acquisition.

    In addition, as described above, Morgan Stanley's opinion and presentation
to Hilton's board of directors was one of many factors taken into consideration
by the board in making its determination to recommend adoption of the merger
agreement. Consequently, the Morgan Stanley analyses described above should not
be viewed as determinative of the opinion of the board or the view of the
management of Hilton with respect to the value of Promus or of whether the board
would have been willing to agree to different consideration.

    Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking and financial
advisory business, is continuously engaged in the valuation of businesses and
their securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and

purposes. In the ordinary course of Morgan Stanley's trading and brokerage
activities, Morgan Stanley or its affiliates may at any time hold long or short
positions, trade or otherwise effect transactions, for its own account or for
the account of customers, in the securities or senior loans of Hilton or Promus.

    Pursuant to an engagement letter dated August 11, 1999 between Hilton and
Morgan Stanley, Hilton has agreed to pay to Morgan Stanley a fee of
approximately $7,200,000 and to reimburse Morgan Stanley for its expenses
incurred in performing its services. In the past, Morgan Stanley and its
affiliates have provided financial advisory and financing services to Doubletree
Corporation, which merged with Promus, and have received fees for its services.
Furthermore, Hilton has also agreed to indemnify Morgan Stanley and its
affiliates, their respective directors, officers, agents and employees and each
person, if any, controlling Morgan Stanley or any of its affiliates against
certain liabilities and expenses, including certain liabilities under federal
securities laws, related to or arising out of Morgan Stanley's engagement and
any related transactions. Morgan Stanley may receive additional fees for
providing financing services in connection with this transaction.

    OPINION OF DONALDSON, LUFKIN & JENRETTE SECURITIES CORPORATION

    Hilton asked DLJ as its financial advisor to render an opinion to the Hilton
board of directors as to the fairness to Hilton and the Hilton stockholders,
from a financial point of view, of the acquisition consideration pursuant to the
terms of the merger agreement. DLJ was not retained as an advisor or agent to
Hilton's stockholders or any other person, other than as an advisor to the
Hilton board of directors. On September 3, 1999, DLJ delivered an oral opinion,
subsequently confirmed in writing on September 7, 1999, to the effect that as of
the date of such opinion, and based upon and subject to the assumptions,
limitations and qualifications set forth in such opinion, the acquisition
consideration was fair to Hilton and the Hilton stockholders from a financial
point of view.


    THE FULL TEXT OF DLJ'S OPINION IS ATTACHED TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AS APPENDIX C. HILTON STOCKHOLDERS ARE URGED TO READ DLJ'S
OPINION IN ITS ENTIRETY FOR ASSUMPTIONS MADE, PROCEDURES FOLLOWED, OTHER MATTERS
CONSIDERED AND LIMITS OF THE REVIEW UNDERTAKEN IN ARRIVING AT SUCH OPINION.
DLJ'S OPINION WAS PREPARED FOR THE HILTON BOARD OF DIRECTORS AND IS DIRECTED
ONLY TO THE FAIRNESS OF THE ACQUISITION CONSIDERATION TO HILTON AND THE HILTON
STOCKHOLDERS FROM A FINANCIAL POINT OF VIEW AND DOES NOT ADDRESS THE MERITS OF
THE UNDERLYING DECISION BY HILTON TO ENGAGE IN THE ACQUISITION OR OTHER BUSINESS
STRATEGIES CONSIDERED BY THE HILTON BOARD OF DIRECTORS. DLJ'S OPINION DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY HILTON STOCKHOLDER AS TO HOW SUCH STOCKHOLDER
SHOULD VOTE AT THE HILTON STOCKHOLDERS MEETING.


    DLJ's opinion does not constitute an opinion as to the price at which the
Promus common stock or the Hilton common stock will actually trade at any time.
The acquisition consideration was determined in arms-length negotiations between
Hilton and Promus. DLJ advised Hilton in connection with these negotiations. No
restrictions or limitations were imposed by Hilton upon DLJ with respect to the
investigations made or the procedures followed by DLJ in rendering its opinion.


    In arriving at its opinion, DLJ reviewed, among other things, an executed
copy of the merger agreement, dated as of September 3, 1999. DLJ also reviewed
financial and other information that was publicly available or furnished to DLJ
by Hilton and Promus including information provided during discussions with
their respective management. Included in the information provided during
discussions with the respective management were certain financial projections of
Promus for the period beginning July 31, 1999 and ending December 31, 2003
prepared by the management of Hilton and certain financial projections of Hilton
for the period beginning July 31, 1999 and ending December 31, 2003 prepared by
the management of Hilton. In addition, DLJ compared certain financial and
securities data of Hilton and Promus with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of the common stock of Promus and Hilton, reviewed prices
and premiums paid in certain other business combinations and conducted such
other financial studies, analyses and investigations as DLJ deemed appropriate
for purposes of its opinion.



    In rendering its opinion, DLJ relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
DLJ from public sources, that was provided to


                                       46
<PAGE>

DLJ by Hilton and Promus or their respective representatives, or that was
otherwise reviewed by DLJ. In particular, DLJ relied upon the estimates of the
management of Hilton of the projected operating synergies possible as a result
of the acquisition and upon its discussion of such synergies with the management
of Promus. With respect to the financial projections supplied to DLJ by Hilton,
DLJ relied on representations of Hilton that they were reasonably prepared on
the basis reflecting the best currently available estimates and judgments of the
management of Hilton as to the future operating and financial performance of
Hilton and Promus. DLJ has not assumed any responsibility for making any
independent evaluation of any assets or liabilities or for making any
independent verification of any of the information reviewed by DLJ. DLJ has also
assumed that the acquisition will result in no corporate level taxation for
Hilton or Promus.


    DLJ's opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to DLJ as of,
the date of its opinion. It should be understood that, although subsequent
developments may affect its opinion, DLJ does not have any obligation to, nor
did it, update, revise or reaffirm its opinion. DLJ is expressing no opinion as
to the prices at which Hilton or Promus securities will actually trade at any
time. DLJ's opinion does not address the relative merits of the acquisition and
the other business strategies being considered by Hilton's or Promus' board of
directors, nor does it address either company's board of director's decision to
proceed with the acquisition. DLJ's opinion does not constitute a recommendation
to any stockholder as to how such stockholder should vote on the proposed
transaction or as to what election regarding form of consideration any such
stockholder should make.

    SUMMARY OF FINANCIAL ANALYSIS PERFORMED BY DLJ.  The following is a summary
of the principal aspects of certain financial analysis performed by DLJ in
connection with its oral opinion and the presentation of its written opinion
dated September 7, 1999:


        ACCRETION/DILUTION ANALYSIS.  DLJ analyzed the pro forma financial
impact of the acquisition assuming the acquisition would close at the end of
fiscal year 1999. DLJ compared the projected earnings per share, cash earnings
per share and after-tax cash flows per share of Hilton, assuming the acquisition
had not occurred, to that of the new company based on projections for both
Hilton and Promus provided by Hilton management. Earnings per share were
calculated as net income to common stock divided by the fully diluted shares
outstanding using the treasury method and adjusted for any dilutive effects of
Hilton's convertible notes and the acquisition on a pro forma basis, as
appropriate. Cash earnings per share were calculated as net income to common
stock plus goodwill amortization expense divided by the fully diluted shares
outstanding using the treasury method and adjusted for any dilutive effects of
the convertible notes and the acquisition on a pro forma basis, as appropriate.
After-tax cash flows per share were calculated as net income to common stock
plus depreciation and amortization expense divided by the fully diluted shares
outstanding using the treasury method and adjusted for any dilutive effects of
the convertible notes and the acquisition on a pro forma basis, as appropriate.
DLJ used Hilton management's assumptions with respect to Hilton and Promus
operating synergies, including the phase-in period for achieving those
synergies. DLJ's analysis of the acquisition, assuming the maximum exchange
ratio under the merger agreement, showed that, in 2000, the acquisition,
compared to continued operation of Hilton on a stand-alone basis, would be
dilutive to earnings per share, modestly dilutive to cash earnings per share,
and accretive to after-tax cash flow per share. DLJ's analysis of the
acquisition, assuming the minimum exchange ratio under the merger agreement,
showed that, in 2000, the acquisition, compared to continued operation of Hilton
on a


                                       47
<PAGE>

stand-alone basis, would be dilutive to earnings per share, modestly accretive
to cash earnings per share, and accretive to after-tax cash flow per share.


    ANALYSIS OF CERTAIN OTHER PUBLICLY TRADED COMPANIES.  DLJ compared selected
common stock prices, earnings and operating and financial ratios for Promus,
based on consideration per share for Promus common stock of $38.50 both taking
into account and excluding the anticipated operating synergies, to the
corresponding data and ratios of certain comparable companies whose securities
are publicly traded, including Hilton, based on September 2, 1999 prices for the
common stock of these comparable companies. The comparable companies were chosen
because they possess general business, operating and financial characteristics
representative of companies in the industry in which Promus operates. The
comparable companies consisted of Marriott International, Inc., Choice Hotels
International, Inc., Starwood Hotels & Resorts Worldwide, Inc., Wyndham
International, Inc. and Hilton. For each company, DLJ calculated common stock
price to projected calendar 1999 and calendar 2000 earnings per share multiples
and multiples representing ratios of enterprise value, aggregate market equity
value, plus total debt, preferred equity and minority interests, less cash and
cash equivalents and investments in unconsolidated affiliates, to projected
calendar 1999 and 2000 EBITDA, earnings before interest, taxes, depreciation and
amortization expense. Hilton and Promus EBITDA and earnings per share
projections were provided by Hilton management. Projections for comparable
companies were based on published research analysts' reports in the case of
EBITDA and First Call Corporation consensus estimates in the case of earnings
per share. The average enterprise value to calendar 1999 EBITDA ratio for the
comparable companies was 9.2x with no premium for control, as compared to 9.3x
for Promus based on an assumed consideration per share for Promus common stock
of $38.50 in the acquisition.

    DLJ's analysis of certain comparable publicly traded companies necessarily
involves complex considerations and judgments concerning differences in
financial and operating characteristics of Hilton and Promus and other factors
that could affect the public trading values of Hilton, Promus and the other
companies included in such analysis.

    COMPARABLE TRANSACTION ANALYSIS.  DLJ reviewed the following 13 selected
comparable acquisitions announced since September 1996 involving companies DLJ
deemed to be relevant (Acquiror/Target):

    - Accor SA/Red Roof Inns, Inc.,

    - Hilton Group plc/Stakis plc,

                                       48
<PAGE>
    - Bass plc/Inter-Continental Hotels & Resorts Corporation,

    - Patriot American Hospitality, Inc./Arcadian International plc,

    - Meditrust Companies Corporation/La Quinta Inns, Inc.,

    - Patriot American Hospitality, Inc./Interstate Hotels Company,

    - Starwood Hotels & Resorts Worldwide, Inc./ITT Corporation,

    - Starwood Hotels & Resorts Worldwide, Inc./Westin Hotels LP,

    - Promus/Doubletree Corporation,

    - Patriot American Hospitality, Inc./Wyndham International, Inc.,

    - Marriott International, Inc./Renaissance Hotel Group N.V.,

    - Extended Stay America, Inc./Studio Plus Hotels Inc.,

    - Doubletree Corporation/Red Lion Hotels, Inc.

    For purposes of the comparable transaction analysis, total transaction value
was calculated as the aggregate purchase price of equity, in the case of stock
purchases, or the aggregate purchase price of the assets, in the case of asset
purchases, plus total debt, preferred equity and minority interests, less cash
and cash equivalents and investments in unconsolidated affiliates. Investments
in unconsolidated affiliates was only subtracted if the related investment
income was excluded from EBITDA. For each of the comparable transactions, DLJ
calculated an EBITDA multiple representing the ratio of transaction value to the
next full calendar year EBITDA estimate. Promus forward EBITDA was provided by
Hilton management. Forward EBITDA for comparable companies was based on
published research analysts' reports. The analysis resulted in an average EBITDA
multiple of 11.2x for the comparable transactions, compared to 9.0x for Promus,
excluding synergies, based on an assumed consideration per share for Promus
common stock of $38.50 in the acquisition.

    No transaction utilized in the comparable transaction analysis is identical
to the acquisition. Accordingly, such analysis necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of Hilton and Promus and other factors that could affect the
acquisition value of the companies to which they are being compared.

        PREMIUMS PAID ANALYSIS.  DLJ determined the premiums paid or to be paid
over the common stock trading prices for selected acquisitions of publicly
traded companies announced since January 1, 1999 with total transaction values
greater than $1.0 billion. For each selected transaction, DLJ calculated such
premiums paid or to be paid for one-day, one-week, and four-weeks prior to the
announcement of the transaction. The mean premiums for these transactions over
the closing prices

                                       49
<PAGE>
one day, one week and four weeks prior to the announcement of the transactions
were 33.1%, 40.3% and 47.9%, as compared to 21.5%, 34.4% and 44.2% based on
Promus' respective closing common stock prices and consideration per share for
Promus common stock of $38.50 in the acquisition.

    No transaction utilized in the premiums paid analysis is identical to the
acquisition. Accordingly, such analysis necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of Hilton and Promus and other factors that could affect the
acquisition value of the companies to which they are being compared.

        DISCOUNTED CASH FLOW ANALYSIS.  DLJ performed a discounted cash flow
analysis to estimate a range of present values per share of Promus common stock
assuming it continued to operate as a stand-alone entity. DLJ performed this
analysis both including and excluding the synergies estimated by the management
of Hilton as set forth above. These ranges were determined by adding the present
value of the estimated future free cash flow that Hilton management estimated
Promus could generate through December 31, 2003 and the present value of the
"terminal value" of Promus at December 31, 2003. Free cash flow is defined as
earnings before interest and taxes, net of tax expenses, plus depreciation and
amortization expense, less changes in working capital and capital expenditures.

    DLJ determined the range of present values per share of Promus common stock
using the terminal year multiples and discount rates that DLJ viewed as
appropriate for companies with its risk characteristics. DLJ relied on Hilton
management estimates of Promus' future cash flows and operating data.

    In calculating a terminal value of Promus common stock at December 31, 2003,
DLJ applied multiples ranging from 8.0x to 10.0x to forecasted EBITDA for fiscal
year 2003. The free cash flows and terminal values were then discounted back to
December 31, 1999 using discount rates ranging from 10.0% to 13.0%. Based on
these assumptions, the stand-alone present value of Promus common stock ranged
from $31.86 to $46.10 per share. Assuming the amount of all the synergies
described above were to be reflected in the future value of Promus, the present
value of Promus common stock ranged from $39.62 to $56.31.

    The discounted cash flow analyses are not necessarily indicative of actual
values or actual future results and do not purport to reflect the prices at
which any securities may trade at the present time or at any time in the future.
Discounted cash flow analysis is a widely used valuation methodology, but the
results of this methodology are highly dependent upon the numerous assumptions
that must be made, including earnings growth rates, working capital growth,
capital expenditure growth, terminal values and discount rates.

    The summary set forth above describes the material elements of the
presentation made by DLJ to the Hilton board on September 3, 1999. The
preparation of a fairness opinion involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to summary description. Each of the analyses conducted
by DLJ was carried out in order to provide a different perspective on the
transaction and add to the total mix of information available. DLJ did not form
a conclusion as to whether any individual analysis, considered in isolation,
supported or failed to support an opinion as to fairness from a financial point
of view. Rather, in reaching its conclusion, DLJ considered the results of the
analyses in light of each other and ultimately reached its opinion based on the
results of all analyses taken as a whole. DLJ did not place particular reliance
or weight on any individual analysis, but instead concluded that its analyses,
taken as a whole, supported its determination. Accordingly, notwithstanding the
separate factors summarized above, DLJ believes that its analyses must be
considered as a whole and that selecting portions of its analysis and the
factors considered by it, without considering all analyses and factors, could
create an incomplete or misleading view of the evaluation process underlying its
opinions. In performing its analyses, DLJ made numerous assumptions with respect
to industry performance, business and economic conditions and

                                       50
<PAGE>
other matters. The analyses performed by DLJ are not necessarily indicative of
actual values or future results, which may be significantly more or less
favorable than suggested by such analyses.

    Pursuant to the terms of an engagement letter, dated September 3, 1999,
Hilton agreed to pay DLJ (a) a fee of $600,000 payable promptly upon the
execution of a definitive agreement providing for the acquisition of the Promus
by Hilton and (b) an additional cash compensation of $4.8 million, less the
initial $600,000 fee, payable upon consummation of the acquisition. Hilton has
also agreed to reimburse DLJ promptly for all out-of-pocket expenses, including
the reasonable fees and out-of-pocket expenses of counsel, incurred by DLJ in
connection with its engagement, and to indemnify DLJ and related persons against
liabilities in connection with its engagement, including liabilities under the
federal securities laws. The terms of the fee arrangement with DLJ, which DLJ
and Hilton believe are customary in transactions of this nature, were negotiated
at arms-length between Hilton and DLJ and the Hilton board of directors was
aware of such arrangement, including the fact that a significant portion of the
aggregate fee payable to DLJ is contingent upon consummation of the acquisition.

    In the ordinary course of business, DLJ may actually trade the securities of
both Hilton and Promus for its own account and for the accounts of its customers
and accordingly, may at any time hold a long or short position in such
securities.

    DLJ, as part of its investment banking services, is regularly engaged in the
valuation of businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. DLJ has
performed investment banking and other services for Hilton in the past and has
been compensated for such services. DLJ co-managed $200 million of Senior Notes
due 2009 and $200 million of Senior Notes due 2017 for the Company in
December 1997, lead-managed a $773 million offering of the Company's common
stock in April 1998, delivered a fairness opinion to the Company in connection
with a spin-off of its gaming assets to its shareholders and the simultaneous
acquisition of the gaming business of Grand Casinos, Inc. in June 1998 and acted
as dealer manager and lead consent solicitation agent for Park Place
Entertainment Corporation, a wholly owned subsidiary of the Company at the time,
in connection with a tender offer and consent solicitation for $450 million of
Grand Casinos' First Mortgage Notes due 2003 in December 1998. DLJ received
usual and customary compensation in connection with these transactions.

OPINION OF PROMUS FINANCIAL ADVISOR

    OPINION OF SALOMON SMITH BARNEY INC.

    Salomon Smith Barney was retained by Promus to act as its financial advisor
in connection with the acquisition and the merger agreement. In connection with
such engagement, Promus requested that Salomon Smith Barney evaluate the
fairness, from a financial point of view, to holders of Promus common stock of
the consideration to be received by such holders pursuant to the terms of the
merger agreement. On September 3, 1999, at a meeting of the Promus board of
directors held to approve the merger agreement, Salomon Smith Barney delivered
an oral opinion, which was subsequently confirmed in writing, to the Promus
board of directors to the effect that, as of the date of such opinion and based
upon and subject to certain matters stated therein, the consideration to be
received in the acquisition by holders of Promus common stock was fair from a
financial point of view to the stockholders.

    In arriving at its opinion, Salomon Smith Barney reviewed the merger
agreement and held discussions with certain officers and employees of Promus and
Hilton concerning the business, operations, financial condition and prospects of
Promus and Hilton. Salomon Smith Barney examined certain publicly available
information relating to Promus and Hilton as well as certain other financial
information concerning Promus and Hilton which were provided to or otherwise
discussed with Salomon Smith Barney by Promus and Hilton respectively. Salomon
Smith Barney reviewed the financial terms of the acquisition in relation to,
among other things: (i) current and historical market

                                       51
<PAGE>
prices and trading volumes of the Promus common stock; (ii) the historical and
projected earnings and other operating data of Promus; and (iii) the
capitalization and financial condition of Promus. Salomon Smith Barney also
considered, to the extent publicly available, the financial terms of certain
other similar transactions effected which Salomon Smith Barney considered
relevant in evaluating the acquisition and analyzed certain financial, stock
market and other publicly available information relating to the businesses of
other companies whose operations Salomon Smith Barney considered relevant in
evaluating those of Promus. In addition to the foregoing, Salomon Smith Barney
conducted such other analyses and examinations and considered such other
financial, economic and market criteria as Salomon Smith Barney deemed
appropriate in arriving at its opinion. Salomon Smith Barney noted that its
opinion was necessarily based upon information available and conditions as they
existed and could be evaluated on the date of its opinion.

    In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney. With respect to the
financial forecasts of Promus and Hilton, Salomon Smith Barney has assumed that
they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the managements of Promus and Hilton as to
the future financial performance of Promus and Hilton and Salomon Smith Barney
expresses no opinion with respect to such forecasts. Salomon Smith Barney did
not make and was not provided with an independent evaluation or appraisal of any
of the assets or liabilities (contingent or otherwise) of Promus or Hilton nor
did Salomon Smith Barney make any physical inspection of the properties,
facilities or assets of Promus and Hilton.

    At the meeting of the Promus board of directors held on September 3, 1999,
Salomon Smith Barney made a presentation to the Promus board of directors
regarding the acquisition. The following is a summary of the material financial
analyses of Salomon Smith Barney included in such presentation:

        PUBLIC MARKET VALUATION.  Using publicly available information, Salomon
Smith Barney analyzed the market values and trading multiples of the following
five publicly traded companies in the lodging industry:

    - Choice Hotels

    - Marriott International, Inc.

    - Hilton

    - Starwood Hotels & Resorts Worldwide, Inc.

    - Wyndham International, Inc.

    Salomon Smith Barney compared, among other things, equity values as a
multiple of estimated calendar years 1999 and 2000 earnings per share, commonly
called "EPS," and firm values, calculated as equity value, plus total debt and
minority interests, less cash, as multiples of estimated calendar year 1999 and
2000 earnings before interest, taxes, depreciation and amortization, commonly
called "EBITDA." All multiples were based on closing stock prices on September
2, 1999. Estimated financial data for the selected lodging companies were based
on publicly available research analysts' estimates and estimated financial data
for Promus were based on internal estimates of the management of Promus.

    Applying a range of multiples derived from the selected lodging companies of
estimated calendar 1999 and 2000 EPS and estimated calendar 1999 and 2000 EBITDA
to corresponding financial data of Promus resulted in an implied equity
reference range for Promus of approximately $33.98 to $38.98 per share, as
compared to the acquisition consideration of approximately $38.50 per share.

        PRIVATE MARKET VALUATION.  Using publicly available information, Salomon
Smith Barney reviewed the purchase prices and implied transaction value
multiples paid or proposed to be paid in the following 12 selected transactions
in the lodging industry:

</TABLE>

    Salomon Smith Barney compared purchase prices in the selected transactions
as a multiple of one-year forward EBITDA. All multiples were based on publicly
available financial information for the relevant transaction. Applying a range
of multiples derived from the selected transactions of one-year forward EBITDA
to estimated calendar year 2000 EBITDA of Promus resulted in an implied equity
reference range for Promus of approximately $44.67 to $56.16 per share, as
compared to the acquisition consideration of approximately $38.50 per share.

    Salomon Smith Barney also employed the concept of an adjusted forward EBITDA
multiple analysis, which it believed was a more appropriate valuation measure
than that described in the previous paragraph given the current market
circumstances. The averages of the forward price to earnings multiples for
Marriott International, Hilton and Choice Hotels for the period January 1997 to
May 1998 were compared to those for the period May 1998 to July 1999. This
analysis revealed that the average multiples for the latter period were 26% less
than the earlier period. This discount of 26% was then applied to the forward
multiples of the precedent transactions that were announced in the January 1997
to May 1998 time period to derive an adjusted forward EBITDA multiple. Applying
a range of multiples derived from the adjusted forward multiple EBITDA analysis
to Promus' 2000 EBITDA resulted in an implied equity reference range for Promus
of approximately $34.23 to $43.41 per share, as compared to acquisition
consideration of approximately $38.50 per share.

        DISCOUNTED CASH FLOW ANALYSIS.  Salomon Smith Barney performed a
discounted cash flow analysis of Promus to estimate a range of values for the
Promus common stock. The discounted cash flow analysis for Promus was based upon
certain financial forecasts for the years 1999 through 2003 prepared by the
management of Promus. Salomon Smith Barney performed a discounted cash flow
analysis of Promus in order to determine the aggregate net present value of the
unlevered free cash flows of Promus' businesses, net of the outstanding debt
balances. A terminal value multiple range of 8.5x to 10.5x was applied to the
projected EBITDA in year 2003. The unlevered free cash flows were then
discounted to present value using discount rates ranging from 9.5% to 11.5%.
This analysis of the forecasts for Promus indicated an implied equity value
range per share of Promus common stock of approximately $35.03 to $40.31 on a
fully diluted basis, as compared to the acquisition consideration of
approximately $38.50 per share.

    Salomon Smith Barney also performed a discounted cash flow analysis of
Hilton to estimate a range of values for the common stock of Hilton. The
discounted cash flow analysis for Hilton was based upon certain financial
forecasts for the years 1999 through 2003 prepared by the management of

                                       53
<PAGE>
Hilton. Salomon Smith Barney performed a discounted cash flow analysis of Hilton
in order to determine the aggregate net present value of the unlevered free cash
flows of Hilton's businesses, net of the full payment of outstanding debt
balances. A terminal value multiple range of 7.5x to 9.5x was applied to the
projected EBITDA in year 2003. The unlevered free cash flows were then
discounted to present value using discount rates ranging from 10.0% to 12.0%.
This analysis of the forecasts for Hilton indicated an implied equity value
range per share of Hilton common stock of approximately $12.96 to $16.72 on a
fully diluted basis.

        OTHER FACTORS.  In rendering its opinion, Salomon Smith Barney also
reviewed and considered, among other things:

    - a business, financial and shareholder profile of Promus and Hilton;

    - the relationship between movements in Promus common stock and movements in
      the common stock of selected companies in the lodging industry and the
      relationship between movements in Hilton stock and movements in selected
      companies in the lodging industry; and

    - selected analysts' reports on Hilton, including reports containing 1999
      and 2000 EPS estimates.

    In preparing its opinion to the Promus board of directors, Salomon Smith
Barney performed a variety of financial and comparative analyses, including
those described above, in connection with its opinion dated September 3, 1999.
The summary of described analyses does not purport to be a complete description
of the analyses underlying Salomon Smith Barney's opinion. The preparation of a
fairness opinion is a complex analytic process involving various determinations
as to the most appropriate and relevant methods of financial analyses and the
application of those methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. Salomon Smith
Barney believes that its analyses must be considered as a whole and that
selecting portions of such analyses or any of the individual factors considered,
without considering all analyses and factors, could create a misleading or
incomplete view of the processes underlying such analyses and its opinion. In
its analyses, Salomon Smith Barney made numerous assumptions with respect to
Promus, industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Promus.
The estimates contained in such analyses and the valuation ranges resulting from
any particular analysis are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than those suggested by such analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty.

    Pursuant to the terms of Salomon Smith Barney's engagement, Promus has
agreed to pay Salomon Smith Barney for its services in connection with the
acquisition an estimated financial advisory fee of $14 million, a substantial
portion of which is contingent upon the consummation of the acquisition. Promus
has also agreed to indemnify Salomon Smith Barney and related persons against
certain liabilities, including liabilities under the federal securities laws,
arising out of Salomon Smith Barney's engagement.

    Salomon Smith Barney has advised Promus that, in the ordinary course of
business, Salomon Smith Barney and its affiliates may actively trade or hold the
securities of Promus and Hilton for their own account or for the account of
customers and, accordingly, may at any time hold a long or short position in
such securities. Salomon Smith Barney has in the past provided certain
investment banking services to Hilton unrelated to the acquisition, for which
services Salomon Smith Barney has received customary compensation. In addition,
Salomon Smith Barney and its affiliates, including Citigroup Inc. and its
affiliates, may maintain relationships with Promus, Hilton and their respective
affiliates.

    THE FULL TEXT OF THE WRITTEN OPINION OF SALOMON SMITH BARNEY DATED
SEPTEMBER 3, 1999, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX D AND IS
INCORPORATED HEREIN BY REFERENCE. HOLDERS OF PROMUS COMMON STOCK ARE URGED TO
READ THIS OPINION CAREFULLY IN ITS ENTIRETY. SALOMON SMITH BARNEY'S OPINION IS
ADDRESSED TO THE BOARD OF DIRECTORS OF PROMUS AND RELATES ONLY TO THE FAIRNESS,
FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO BE RECEIVED BY HOLDERS
OF PROMUS COMMON STOCK IN THE ACQUISITION AND DOES NOT ADDRESS ANY OTHER ASPECT
OF THE ACQUISITION OR RELATED TRANSACTIONS. THE SUMMARY OF THE OPINION OF
SALOMON SMITH BARNEY SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

STRUCTURE OF THE ACQUISITION


    In the acquisition, each share of Promus common stock other than shares held
by Hilton, Promus or any of their respective subsidiaries and shares with
respect to which dissenters' appraisal rights have been perfected will be
converted into either $38.50 in cash or a number of shares of Hilton common
stock determined as described elsewhere in this joint proxy
statement/prospectus, such that 55% of the number of shares of Promus common
stock outstanding immediately prior to the closing will be converted into cash
and the remaining 45% of the Promus shares will be converted into Hilton common
stock.


    As long as the value of the Hilton common stock delivered in the acquisition
is at least 40% of the total consideration described below, the transaction will
be effected using the forward merger structure, under which Promus will merge
into PRH Acquisition, and PRH Acquisition will be the surviving corporation.
However, the companies will not use the forward merger structure in either of
the following circumstances:


    - on the closing date, the fair market value, based on the volume weighted
      average per share sales price of Hilton common stock on that day on the
      NYSE, of all shares of Hilton common stock to be delivered in the
      acquisition is less than 40% of the sum of:


       -- the cash consideration paid in the acquisition, determined by:

           * adding together the total number of shares of Promus common stock
             that receive cash consideration in the acquisition and the total
             number of shares of Promus common stock for which dissenters'
             rights are exercised, and

           * multiplying that number by $38.50;


       -- $14.2 million, which is the amount of cash paid by Hilton to acquire
          shares of Promus common stock within the two-year period before the
          date of the acquisition; and


       -- the fair market value of all shares of Hilton common stock to be
          delivered in the acquisition; or


    - the tax opinions described under "The Merger Agreement--Conditions to the
      Completion of the Acquisition," on page 75 cannot otherwise be delivered,
      assuming that the legally required minimum percentage of stock
      consideration under the continuity of interest test applicable pursuant to
      U.S. Treasury Regulations promulgated under the Internal Revenue Code is
      40%.


                                       55
<PAGE>
Under either of these circumstances, the companies will implement the reverse
merger structure, under which PRH Acquisition will merge into Promus and Promus
will be the surviving corporation and a wholly-owned subsidiary of Hilton. The
purpose of this modification to the structure is to avoid the substantial
corporate level tax that would result if the acquisition were to be structured
as a forward merger and were to fail to satisfy the requirements for a tax-free
reorganization under Section 368(a) of the Internal Revenue Code.


    The tax consequences to the Promus stockholders under each of the
acquisition structures will differ, and the structure will not be determined
until immediately before closing. As a result, Promus stockholders will not know
at the time they vote what the tax consequences of the acquisition will be.
These tax consequences are discussed in the section titled "The
Acquisition--Certain Federal Income Tax Consequences of the Acquisition" on page
60.


    As an alternative to both the forward merger structure and the reverse
merger structure, the merger agreement provides that the companies will use
their best efforts to implement a holding company structure if both Hilton and
Promus agree that a holding company structure will not result in any material
adverse consequences under any material indebtedness of Hilton. Under this
structure, Hilton and Promus would form a new holding company, which in turn
would form two wholly-owned subsidiaries. One subsidiary would merge into
Hilton, with Hilton being the surviving corporation, and the other subsidiary
would merge into Promus, with Promus being the surviving corporation. As a
result, both Hilton and Promus would become subsidiaries of the new holding
company.


    Under this structure, the stock consideration component of the acquisition
would be satisfied by the issuance of holding company common stock and each
outstanding share of Hilton common stock would be converted into one share of
holding company common stock. Promus stockholders would receive holding company
common stock based on the exchange ratio calculated on the Hilton common stock
trading price described in "The Merger Agreement--Consideration to be Received
for Promus Common Stock in the Acquisition," and Hilton stockholders would have
their Hilton shares converted into holding company shares on a one-for-one
basis. The result would be that Hilton and Promus stockholders would hold
holding company common stock in the same proportions as they would have held
Hilton common stock if either of the other structures had been used.
Implementation of the holding company structure would require amendments to the
merger agreement and a supplement to this joint proxy statement/prospectus.
Since Hilton and Promus have not agreed that the holding company structure will
not result in material adverse consequences under any material indebtedness of
Hilton, we do not currently intend to implement the holding company structure.


INTERESTS OF CERTAIN PERSONS IN THE ACQUISITION

    In considering the recommendation of the Promus board of directors to
approve the acquisition, Promus stockholders should consider that some of
Promus' directors and officers have interests in the acquisition that differ
from, or are in addition to, their interests as Promus stockholders. Promus'
directors and officers may receive benefits from the acquisition not available
to Promus stockholders generally. The Promus board of directors was aware of
these interests and considered them, among other matters, in approving the
merger agreement and the transactions contemplated by the merger agreement.

    DIRECTORS AND EXECUTIVE OFFICERS


    See "Hilton After the Acquisition--Management" on page 78.


    INCENTIVE COMPENSATION AND STOCK OWNERSHIP ARRANGEMENTS


    Promus' key management employees and directors are participants in incentive
compensation and stock ownership plans currently maintained by Promus.
Generally, options outstanding under these


                                       56
<PAGE>

plans contain change of control provisions that provide for accelerated vesting
upon completion of the vote of Promus stockholders approving the acquisition.



    Under the merger agreement, generally, each outstanding Promus employee and
directors stock option will be canceled at the closing of the acquisition, and
Promus or Hilton will pay the holder of the stock option, at or promptly after
the effective time, an amount in cash determined by multiplying:


    - the excess, if any, of $38.50 over the applicable exercise price of such
      Promus stock option by

    - the number of Promus shares the option holder could have purchased,
      assuming full vesting of the option, had the holder exercised the option
      in full immediately prior to the effective time.


    The following table shows the number of unvested options held by individuals
who were Promus' seven most highly compensated executive officers as of the end
of 1998, all other executive officers as a group, and all other directors as a
group, as well as the aggregate value of the unvested options, which are subject
to accelerated vesting as discussed earlier, assuming the acquisition is
completed on November 30, 1999. Unless otherwise noted, the information in the
following table is as of October 15, 1999.

Plan or the Independent Director Equity Participation Program under The 1997
Equity Participation Plan of Promus Hotel Corporation will have the same
opportunity to elect to receive cash or Hilton common stock for the deferred
shares, subject to proration, as Promus stockholders. As of October 15, 1999,
independent directors as a group were credited with 11,057 deferred shares of
Promus common stock under these two plans.


    A more detailed description of the benefits under Promus' incentive
compensation and stock ownership plans may be found in Promus' 1998 Proxy
Statement under the heading "Executive Officer Compensation."

    SEVERANCE AGREEMENTS AND ARRANGEMENTS


    Specified Promus employees, including all executive officers named in the
preceding table, are parties to employment or severance agreements. Among other
things, the agreements provide for a lump sum payment based on a specified
multiple of annual base salary, bonus amount and a benefit allowance equal to
25% of the officer's then current annual base salary, as well as the payment of
earned or accrued and other customary severance benefits, in the event of a
termination of employment under circumstances specified in the agreements. An
executive officer who is covered by an employment or severance agreement is
entitled to receive severance benefits if (x) Hilton or the surviving
corporation terminates his or her employment without "cause," as defined in the
agreement, or (y) the executive terminates his or her employment with "good
reason," as defined in the agreement, in either case within two years following
the acquisition. For this purpose, "good reason" generally includes the
executive's voluntary termination for any reason within the 30-day period
immediately following the first anniversary of the completion of the
acquisition, except that under the agreements applicable to Messrs. Blake and
Keltner, "good reason" includes the executive's voluntary termination for any
reason during the two-year period following completion of the acquisition. In
connection with the merger agreement, Promus has also agreed to pay relocation
benefits to certain of its executive officers in the event of a termination of
their employment that results in the payment of severance benefits, in an amount
sufficient to make such officers whole for the costs (including loss in home
value) incurred in moving to another city.


    Under the agreements, officers receiving severance benefits agree for a
two-year period to certain restrictions relating to confidentiality,
nonsolicitation of Promus employees and non-interference with hotel development
opportunities. They also agree for a period of three years to cooperate with
Promus on matters with which they were involved while employed.

    Under the agreements, Promus is required, if necessary, to make an
additional gross-up payment to any covered employee to offset fully the effect
of any excise tax imposed by Section 4999 of the Internal Revenue Code on any
excess parachute payment, whether made to that employee under his or her
severance agreement or otherwise.

    payable in accordance with the merger agreement upon specified terminations
    of employment.

    A more detailed description of the severance benefits payable under these
agreements may be found in Promus' 1998 Proxy Statement under the heading
"Executive Officer Compensation--Severance Agreements."

    Promus also maintains more broadly based severance agreements and plans that
will provide benefits to its other officers and employees in the event of
termination of employment under certain circumstances following the acquisition.


    ARRANGEMENTS WITH MR. BLAKE



    Norman P. Blake, Jr. serves as the Chairman of the Board, President and
Chief Executive Officer of Promus pursuant to an employment agreement entered
into as of December 3, 1998, and is also a party to a severance agreement
entered into as of January 13, 1999. Promus and Mr. Blake have agreed to
arrangements relating to the termination of Mr. Blake's employment effective
upon the closing of the acquisition. Pursuant to these arrangements, the parties
confirmed that the termination of Mr. Blake's employment on that date would be a
"Covered Termination" entitling him to severance benefits under his existing
severance agreement. The estimated amount of these severance benefits is stated
in the table above. In addition, Promus agreed to pay Mr. Blake an aggregate
amount of $5,128,000, minus withholding taxes, in full satisfaction of other
rights to benefits and entitlements under his employment and severance
agreements. The arrangements also confirm Mr. Blake's right to lifetime medical
benefits for himself and his wife, in accordance with his employment agreement.
More detailed descriptions of the terms of Mr. Blake's existing employment and
severance agreements may be found in Promus' 1998 Proxy Statement under the
headings "Executive Officer Compensation--Employment Agreements--Norman P.
Blake, Jr." and "Executive Officer Compensation--Severance Agreements--Norman P.
Blake, Jr."


    DEFERRED COMPENSATION BENEFITS

    Promus' Capital Accumulation Plan for Executives, a deferred compensation
plan in which many of Promus' executive officers participate, provides that upon
completion of a transaction such as the acquisition, participants will vest,
upon termination of employment within 24 months, in the right to a higher
interest crediting rate on their account balances than would otherwise apply.

                                       59
<PAGE>
    In addition, certain funding arrangements maintained in connection with
Promus' deferred compensation plans, including the Capital Accumulation Plan for
Executives, contain provisions requiring enhanced or accelerated contributions
by Promus in the event of a transaction such as the acquisition. Any additional
funding required upon completion of the acquisition will serve as additional
security for the payment of benefits under the deferred compensation plans, but
will not itself affect the level of benefits to which participants are entitled
under the plans' terms.

GOVERNMENTAL AND REGULATORY MATTERS



    We have filed the notifications required under the Hart-Scott-Rodino Act
and, on October 14, 1999, the required waiting period was terminated. The
Justice Department, the Federal Trade Commission or any state or foreign
governmental authority could take action under the antitrust laws as it deems
necessary in the public interest. This action could include seeking to enjoin
the acquisition or seeking Hilton's divestiture of Promus or Promus' divestiture
of all or some portion of its business. Private parties may also seek to take
legal action under the antitrust laws under certain circumstances.


    Based on information available to us, we believe that the acquisition will
comply with all significant federal, state and foreign antitrust laws. We cannot
assure you, however, that there will not be a challenge to the acquisition on
antitrust grounds or that, if this challenge were made, we would prevail.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE ACQUISITION

    The following discussion is a summary of the material federal income tax
consequences of the acquisition to Promus stockholders who hold their shares of
Promus common stock as capital assets. This summary is based upon provisions of
the Internal Revenue Code, applicable Treasury regulations promulgated under the
Internal Revenue Code, and judicial and administrative decisions currently in
effect. All of these authorities are subject to retroactive or prospective
change and to possibly differing interpretations. This discussion does not
address the federal income tax consequences applicable to holders of Promus
common stock who are subject to special treatment under the Internal Revenue
Code, such as foreign holders, holders who acquired their stock pursuant to the
exercise of employee stock options or otherwise as compensation, holders who are
dealers in securities, banks, insurance companies or tax exempt organizations,
and holders who hold their shares of Promus or Hilton common stock as part of a
hedge, straddle, or other risk reduction transaction. In addition, this
discussion does not address the tax consequences of the acquisition under
applicable foreign, state or local tax laws. STOCKHOLDERS ARE URGED TO CONSULT
WITH THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE ACQUISITION,
INCLUDING THE EFFECTS OF STATE, LOCAL AND FOREIGN TAX LAWS.

                                       60
<PAGE>
    SUMMARY


    The federal income tax consequences resulting from the acquisition will
differ depending on whether the forward merger structure or the reverse merger
structure is used.



    - If the forward merger structure is used, Hilton will receive an opinion
      from its counsel, Gibson, Dunn & Crutcher LLP, and Promus will receive an
      opinion from its counsel, Davis Polk & Wardwell, substantially to the
      effect that the acquisition will qualify as a reorganization under Section
      368(a) of the Internal Revenue Code. The federal income tax consequences
      of the forward merger structure are discussed below under the heading "Tax
      Consequences of the Forward Merger Structure" on page 62.



    - If the reverse merger structure is used, the acquisition will not
      constitute a reorganization under Section 368(a). Instead, it will be
      treated as a sale of Promus common stock fully taxable to the Promus
      stockholders as discussed below under the heading "Tax Consequences of the
      Reverse Merger Structure" on page 64.



    We will not know until the closing of the acquisition whether the forward
merger structure or the reverse merger structure will be used. As a result,
Promus stockholders will not know the tax consequences to them of the
acquisition at the time they vote on it. THE FORWARD MERGER STRUCTURE WILL BE
USED IF THE ACQUISITION QUALIFIES AS A REORGANIZATION UNDER SECTION 368(A) OF
THE INTERNAL REVENUE CODE. IF THE ACQUISITION DOES NOT SO QUALIFY, THE REVERSE
MERGER STRUCTURE WILL BE USED. The purpose of using the reverse merger structure
is to avoid the substantial corporate level tax that would result if the
acquisition were to be structured as a forward merger and were to fail to
satisfy the requirements for a tax-free reorganization under Section 368(a) of
the Internal Revenue Code. One of the requirements that must be satisfied in
order for the acquisition to qualify as a reorganization under Section
368(a) of the Internal Revenue Code is the continuity of interest requirement.
This requirement will be satisfied if the Promus stockholders exchange a
substantial portion of their proprietary interests in Promus for proprietary
interests in Hilton. The Internal Revenue Service takes the position for advance
ruling purposes that the continuity of interest requirement is satisfied in a
reorganization if the value of the acquiring corporation's stock received in the
reorganization by the acquired corporation's stockholders equals or exceeds 50%
of the total consideration paid for the stock of the acquired corporation in the
reorganization. However, these guidelines only describe the circumstances in
which the Internal Revenue Service will issue a favorable ruling in advance of
the completion of a transaction. They are not a statement of the substantive law
with regard to the continuity of interest requirement. The case law is less
restrictive than the ruling guidelines of the Internal Revenue Service in this
area and, in one early case, the Supreme Court held that the continuity
requirement was satisfied where the stockholders of the acquired company
received stock of the acquiring company having a value of approximately 38% of
the value of the formerly outstanding stock of the acquired company. Hilton and
Promus have thus been advised by their respective tax counsel that the
continuity of interest requirement will be satisfied if at least 40% of the
consideration received by the Promus stockholders in connection with the
acquisition is comprised of Hilton common stock.



    The merger agreement contains a mechanism to ensure that the forward merger
structure is used only if the mix of stock and cash received by the Promus
stockholders is such that it satisfies the 40% continuity of interest threshold.
Pursuant to the merger agreement, the continuity of interest requirement will be
satisfied if on the closing date, the fair market value of the Hilton common
stock, as determined based on the volume weighted average per share sales price
of that stock on that date, delivered in the acquisition is greater than or
equal to 40% of the total consideration delivered in the acquisition. Whether
this requirement will be satisfied depends on certain variables, including in
particular the volume weighted average price of the Hilton common stock on the
closing date. Based on current information, if the price of Hilton common stock
on that date is at least $9.84, the value of the Hilton common stock delivered
to the Promus stockholders in connection with the acquisition will


                                       61
<PAGE>

be at least 40% of the value of the total consideration delivered to Promus
stockholders in the acquisition. In that case, the continuity of interest test
will be satisfied and the acquisition will be completed through the use of the
forward merger structure and will qualify as a reorganization under Section
368(a) of the Internal Revenue Code. However, if the price of Hilton common
stock on that date declines below $9.84, the value of the Hilton common stock
delivered to the Promus stockholders in the acquisition will be less than 40% of
the total consideration delivered to Promus stockholders in the acquisition. In
this event, the continuity of interest requirement will not be satisfied and the
acquisition will be completed through the use of the reverse merger structure
and will not qualify as a reorganization under Section 368(a) of the Internal
Revenue Code. Because the value of the Hilton common stock for purposes of the
40% test will be determined on the closing date, we will not know at the time of
the stockholder meeting whether the acquisition will qualify as a reorganization
under Section 368(a) of the Internal Revenue Code and, therefore, whether the
forward merger structure or the reverse merger structure will be used.


    TAX CONSEQUENCES OF THE FORWARD MERGER STRUCTURE

    If we use the forward merger structure, as conditions to the consummation of
the acquisition, Gibson, Dunn & Crutcher LLP and Davis Polk & Wardwell will give
opinions that the acquisition will qualify as a reorganization under Section
368(a) of the Internal Revenue Code. If the acquisition qualifies as a
reorganization, the federal income tax consequences of the acquisition to a
Promus stockholder will depend on whether the stockholder receives solely Hilton
common stock, solely cash, or a combination of cash and Hilton common stock in
the acquisition. The opinion of each counsel will represent counsel's best
judgment as to the tax treatment of the acquisition and as to the consequences
of the acquisition to Promus stockholders, but will not be binding on the
Internal Revenue Service or the courts. Additionally, these opinions will be
based on certain factual representations and statements by Hilton, Promus and
PRH Acquisition. Any inaccuracy or change in the representations and any future
actions by Hilton or Promus contrary to the representations could adversely
affect the conclusions reached in the opinions and the tax discussion set forth
below.

    THE RECEIPT OF SOLELY HILTON COMMON STOCK BY A PROMUS STOCKHOLDER IN
     EXCHANGE FOR PROMUS COMMON STOCK UNDER THE FORWARD MERGER STRUCTURE


    A Promus stockholder who exchanges all of the shares of Promus common stock
owned by the stockholder for shares of Hilton common stock will not recognize
any gain or loss upon the exchange, except for any gain or loss attributable to
any cash received in lieu of a fractional share of Hilton common stock. The
aggregate tax basis of the shares of Hilton common stock received by the
stockholder in the exchange will be the aggregate tax basis of the shares of
Promus common stock surrendered in the exchange. Also, the stockholder's holding
period for the Hilton common stock received in exchange for shares of Promus
common stock will include the period during which the stockholder held shares of
Promus common stock that were surrendered in the exchange.


    THE RECEIPT OF A COMBINATION OF CASH AND HILTON COMMON STOCK BY A PROMUS
     STOCKHOLDER IN EXCHANGE FOR PROMUS COMMON STOCK UNDER THE FORWARD MERGER
     STRUCTURE

    A Promus stockholder who exchanges the shares of Promus common stock owned
by the stockholder for a combination of cash and shares of Hilton common stock
will not recognize any loss on the exchange. However, the stockholder will
recognize gain equal to the lesser of the amount of cash received and the gain
realized. The gain realized will be the excess of the sum of the fair market
value of Hilton common stock and the amount of cash received in exchange for the
stockholder's shares of Promus common stock that were surrendered in the
exchange over the stockholder's adjusted tax basis in those shares. For this
purpose, a Promus stockholder must calculate gain or loss separately for each
identifiable block of shares of Promus common stock that is surrendered in the
exchange, and

                                       62
<PAGE>
the Promus stockholder may not offset a loss recognized on one block of the
shares against gain recognized on another block of the shares.

    Any gain recognized by a Promus stockholder who receives a combination of
Hilton common stock and cash will generally be treated as capital gain. However,
if the receipt of the cash has "the effect of the distribution of a dividend"
for federal income tax purposes, any gain recognized by the stockholder will be
treated as ordinary dividend income to the extent of the stockholder's ratable
share of the accumulated earnings and profits of Hilton and/or Promus. Any gain
that is treated as capital gain will be long-term capital gain if the holding
period for shares of Promus common stock that are surrendered in the exchange is
greater than one year as of the date of the exchange.

    For purposes of determining whether the cash received has the effect of a
distribution of a dividend for federal income tax purposes, a Promus stockholder
is treated as if the stockholder first exchanged all of the stockholder's shares
of Promus common stock solely for Hilton common stock and then Hilton
immediately redeemed a portion of the Hilton common stock in exchange for the
cash the stockholder actually received. This is called a "deemed redemption."
Under this analysis, in general, if the receipt of cash by the holder in the
deemed redemption results in a "substantially disproportionate" reduction in the
holder's voting stock interest in Hilton or is "not essentially equivalent to a
dividend," the receipt of the cash will not have the effect of the distribution
of a dividend.

    The deemed redemption will be "substantially disproportionate," and,
therefore, will not have the effect of a distribution of a dividend with respect
to a Promus stockholder if the percentage of the outstanding Hilton common stock
that is actually and constructively owned by the stockholder immediately after
the deemed redemption is less than 80% of the percentage of the outstanding
Hilton common stock that is considered to be actually and constructively owned
by the stockholder immediately before the deemed redemption. The deemed
redemption will not be "essentially equivalent to a dividend," and, therefore,
will not have the effect of a distribution of a dividend with respect to a
Promus stockholder if it results in a "meaningful reduction" in the
stockholder's proportionate interest in Hilton. If a stockholder that is
considered to have a relatively minimal stock interest in Hilton and no right to
exercise control over corporate affairs suffers a reduction in the stockholder's
proportionate interest in Hilton, the stockholder should be regarded as having
suffered a meaningful reduction of his or her interest in Hilton. For example,
the Internal Revenue Service has held in a published ruling that, in the case of
a less than 1% stockholder who does not have management control over the
corporation, any reduction in the stockholder's proportionate interest will
constitute a "meaningful reduction."

    In applying this deemed redemption analysis, certain attribution rules apply
in determining a Promus stockholder's ownership interest in Hilton immediately
after the acquisition, but before the deemed redemption, and after the deemed
redemption. Under those rules, a Promus stockholder is deemed to own stock held
by certain family members, estates and trusts of which the stockholder is a
beneficiary, a partnership in which the stockholder is a partner, and a
corporation in which the stockholder is a direct or indirect 50% stockholder, as
well as stock subject to options that are held by the stockholder or the
entities. Because these constructive ownership rules are complex, each Promus
stockholder who believes that he or she may be subject to these rules should
consult his or her tax advisor.

    The aggregate tax basis of the Hilton common stock received by a Promus
stockholder who exchanges his or her shares of Promus common stock for a
combination of Hilton common stock and cash will be the same as the aggregate
tax basis of the shares Promus common stock surrendered in the exchange,
decreased by the amount of cash received, and increased by the amount of gain
recognized, including any portion of the gain that is treated as a dividend. The
holding period of the Hilton common stock received will include the holding
period of the shares of Promus common stock surrendered in exchange therefor. If
a Promus stockholder has differing tax bases and/or holding periods with respect
to the stockholder's shares of Promus common stock that the stockholder

                                       63
<PAGE>
surrenders in the exchange, the stockholder should consult a tax advisor in
order to identify the particular tax bases and/or holding periods of the
particular shares of Hilton common stock received in the exchange.

    THE RECEIPT OF SOLELY CASH BY A PROMUS STOCKHOLDER IN EXCHANGE FOR PROMUS
     COMMON STOCK UNDER THE FORWARD MERGER STRUCTURE


    Currently, the state of the law is unclear as to the analysis that must be
applied in determining the federal income tax consequences to a Promus
stockholder who exchanges all of the shares of Promus common stock owned by the
stockholder solely for cash. The stockholder may be treated as:


    - having sold his or her shares of Promus common stock in a taxable sale or
      exchange;

    - having received shares of Hilton common stock in the merger of Promus into
      PRH Acquisition and having had the shares redeemed by Hilton immediately
      after the acquisition; or

    - having had his or her shares of Promus common stock redeemed by Promus
      prior to the merger.

    However, in most circumstances, both the sales analysis and the redemption
analysis will yield the same tax result to the Promus stockholder.

    If the sales analysis is applied, the Promus stockholder will recognize gain
or loss, measured by the difference between the amount of cash received and the
adjusted tax basis of the Promus common stock surrendered in exchange for the
cash.

    If the redemption analysis is applied, the Promus stockholder will be
treated as having exchanged the Promus stock held by the stockholder for cash,
rather than having received a dividend distribution, if, after applying the
attribution rules discussed above, the redemption is:

    - in complete redemption of all of the Promus stockholder's stock in either
      Hilton or Promus, as the case may be;

    - a substantially disproportionate reduction in the holder's voting stock
      interest in either Hilton or Promus, as the case may be; or

    - not essentially equivalent to a dividend.

    If the redemption qualifies as an exchange, a Promus stockholder will
recognize any gain or loss realized on the exchange. If the redemption does not
qualify as an exchange, the cash received by the Promus stockholder will be
treated as a dividend distribution, and thus as ordinary income, to the extent
of the current and accumulated earnings and profits of the redeeming
corporation. Any excess will be treated as gain from the sale or exchange of the
Promus stock held by the stockholder. However, under those circumstances, the
Promus stockholder will not be permitted to recognize any loss.

    Given the unclear state of the law with respect to the exchange of Promus
stock solely for cash, Promus stockholders who will receive solely cash are
urged to consult their own tax advisors with regard to the receipt of cash.

    TAX CONSEQUENCES OF THE REVERSE MERGER STRUCTURE

    If we complete the acquisition through the use of the reverse merger
structure, the obligations of Hilton and Promus to consummate the acquisition
will not be conditioned upon the issuance of opinions by tax counsel, and the
acquisition will not constitute a reorganization under Section 368(a). Instead,
it will be treated as a sale of Promus stock fully taxable to the Promus
stockholders. In this case, each Promus stockholder will recognize gain or loss
equal to the difference between:

    - the amount of cash plus the fair market value of the Hilton common stock
      received; and

                                       64
<PAGE>
    - the stockholder's adjusted tax basis in the shares of Promus common stock
      surrendered in the exchange.

    CASH RECEIVED IN LIEU OF FRACTIONAL SHARES

    A Promus stockholder who receives cash in lieu of a fractional share of
Hilton common stock will recognize gain or loss equal to the difference between
the amount of cash received and the portion of the adjusted tax basis of the
stockholder's shares of Promus common stock that are allocable to the fractional
interest. Such gain or loss will constitute capital gain or loss, and will
generally be long-term capital gain or loss if the holding period for the shares
was greater than one year as of the date of the exchange.

    TRANSFER TAXES

    Pursuant to the merger agreement, Hilton will pay certain federal, state,
local, foreign or provincial tax that is attributable to the transfer of real
property by Promus or its subsidiaries or that is attributable to the transfer
of Promus common stock or Hilton common stock and that arises from the
acquisition. Payments attributable to the transfer of Promus common stock may be
considered for federal income tax purposes to be additional consideration paid
to each holder of Promus common stock. In that event, each holder would be
treated as if the holder received cash equal to the amount of the taxes that are
paid on its behalf, which could result in additional taxable gain to the holder
and a corresponding increase in tax basis of the holder's shares of Hilton
common stock.

    BACKUP WITHHOLDING

    Under the Internal Revenue Code, a Promus stockholder may be subject, under
certain circumstances, to backup withholding at a 31% rate with respect to the
amount of consideration received pursuant to the acquisition unless the holder
provides proof of an applicable exemption or a correct taxpayer identification
number and otherwise complies with applicable requirements of the backup
withholding rules. Any amounts withheld under the backup withholding rules are
not an additional tax and may be refunded or credited against the holder's
federal income tax liability, provided the required information is furnished to
the Internal Revenue Service.

    THE ABOVE DISCUSSION MAY NOT APPLY TO CERTAIN CATEGORIES OF STOCKHOLDERS
SUBJECT TO SPECIAL TREATMENT UNDER THE INTERNAL REVENUE CODE. STOCKHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE SPECIFIC TAX
CONSEQUENCES OF THE ACQUISITION, INCLUDING ANY FEDERAL, STATE, LOCAL OR OTHER
TAX CONSEQUENCES OF THE ACQUISITION.

DELISTING AND DEREGISTRATION OF PROMUS COMMON STOCK; LISTING OF HILTON COMMON
STOCK ISSUED IN CONNECTION WITH THE ACQUISITION

    Promus common stock is currently listed on the NYSE under the symbol "PRH."
Upon the completion of the acquisition, Promus common stock will be delisted
from the NYSE and deregistered under the Securities Exchange Act.

    Hilton common stock is currently listed on the NYSE under the symbol "HLT."
Hilton has agreed to use its reasonable best efforts to cause the shares of
Hilton common stock to be issued in the acquisition to be approved for listing
on the NYSE.

ACCOUNTING TREATMENT

    Hilton will account for the acquisition as a purchase for accounting and
financial reporting purposes. As a result, Hilton will record Promus' assets and
liabilities at their estimated fair values and

                                       65
<PAGE>
will record as goodwill the excess of the purchase price over the estimated net
fair values. Promus' operating results will be combined with Hilton's results
only from the date of the acquisition.

RECENT LITIGATION


    On or around September 7, 1999, two actions were filed in the Court of
Chancery for the State of Delaware by alleged common stockholders of Promus on
behalf of a purported class of similarly situated Promus stockholders. The
actions are styled STEVEN GOLDSTEIN V. PROMUS HOTEL CORPORATION, ET AL., C.A.
No. 17410NC and JOSEPH CARCO V. PROMUS HOTEL CORPORATION, ET AL., C.A. No.
17411NC. The complaints in the actions, which are substantially similar, name as
defendants Promus, the members of the Promus board of directors and Hilton, and
allege that the Promus directors breached their fiduciary duties to Promus
stockholders by agreeing to the acquisition and by allegedly failing to obtain
the highest value for Promus stockholders, and that Hilton allegedly aided and
abetted such alleged breaches of fiduciary duty. The complaints seek injunctive
relief and monetary damages in an unspecified amount. Defendants intend to
defend the actions vigorously.



    On or about October 11, 1999, an action was filed in the United States
District Court for the Southern District of Florida entitled HOTELRAMA
ASSOCIATES, LTD. V. HILTON HOTELS CORPORATION (Case No. 99-CV02717). The
plaintiff is the owner of the Fontainebleau Hilton Resort & Towers in Miami,
Florida, which is managed by Hilton. The complaint alleges that the acquisition
will cause Hilton to be in violation of territorial restrictions contained in
the management agreement. The complaint seeks an injunction enjoining Hilton
from violating the restrictive covenant by its acquisition of Promus and for the
entry of a judgment entitling the plaintiff to any and all remedies available
under Florida law. Hilton intends to defend the action vigorously.


DISSENTERS' APPRAISAL RIGHTS OF PROMUS STOCKHOLDERS

    Promus' stockholders have the right to dissent from the acquisition and to
receive payment for their shares in accordance with the terms of Section 262 of
the Delaware General Corporation Law. The following discussion is a summary of
the dissenters' rights law under the Delaware law. The entire statute is
reprinted in Appendix E. ANY STOCKHOLDER THAT WISHES TO EXERCISE DISSENTERS'
RIGHTS OR PRESERVE THE RIGHT TO DO SO SHOULD REVIEW THE STATUTE CAREFULLY.
PROMUS STOCKHOLDERS THAT DO NOT COMPLY WITH THE PROCEDURES OF THE STATUTE WILL
LOSE THEIR DISSENTERS' RIGHTS.

    A Promus stockholder that wishes to dissent from the acquisition must
satisfy both of the following conditions, among others:

    - WRITTEN OBJECTION. The stockholder must file a written objection to the
      acquisition with Promus at its offices at 755 Crossover Lane, Memphis,
      Tennessee 38117, Attention: Secretary, before the vote is taken at the
      Promus stockholders meeting.

    - NO VOTE IN FAVOR. The stockholder must not vote in favor of the
      acquisition.


    Promus stockholders that file and do not withdraw a written objection to the
acquisition will not be entitled to elect between cash and Hilton common stock
as acquisition consideration. Any Promus stockholder in that circumstance that
later withdraws the stockholder's demand for appraisal will then receive the
combination of cash and Hilton common stock that is allocated to non-electing
Promus stockholders as a result of the proration procedure discussed in the
section titled "The Merger Agreement--Election and Proration" on page 68.


    A negative vote alone will not constitute the written objection required
before the meeting. The written objection should specify the stockholder's name
and mailing address, the number of shares of Promus common stock owned by the
stockholder and that the stockholder is demanding appraisal of his or her
shares.

                                       66
<PAGE>
    If the Promus stockholders approve the acquisition, Promus will send written
notice to each dissenting stockholder that has filed an objection and not voted
in favor of the acquisition no later than 10 days after consummation of the
acquisition. The notice will state the date that the acquisition has become
effective.

    Within 120 days after the effective time of the acquisition, any dissenting
stockholder that desires to have his or her shares appraised should file a
petition with the Delaware Court of Chancery demanding a determination of the
fair value of the shares of all the dissenting stockholders. Within the same
period, a dissenting stockholder may also make a written request to Promus
demanding a statement by Promus of the number of dissenting Promus stockholders
and the aggregate number of dissenting shares of Promus common stock. Promus
must mail the statement within 10 days after it receives the request.

    If a proper petition for appraisal is timely filed, the Chancery Court will
determine which Promus stockholders, if any, are entitled to appraisal rights.
The Chancery Court may require any stockholders demanding appraisal rights to
submit their certificates of Promus common stock to the Register in Chancery for
notation on these certificates of the pendency of the appraisal proceedings.
Where the proceedings are not dismissed, the Chancery Court will appraise the
shares of Promus common stock owned by the dissenting stockholders by
determining the fair value of the shares exclusive of any element of value
arising out of the accomplishment or expectation of the acquisition and the fair
rate of interest, if any, on the amount determined to be the fair value. In
making this determination of fair value, the Chancery Court must consider the
following factors:

    - market value;

    - asset value;

    - dividends;

    - earnings prospects;

    - the nature of the enterprise; and

    - any other facts which could be ascertained as of the date of the
      acquisition which would throw light on future prospects of the combined
      corporation.

    Promus stockholders considering seeking appraisal should recognize that the
fair value of their shares determined under Section 262 could be more than, the
same as or less than the consideration they are entitled to receive pursuant to
the merger agreement if they do not seek appraisal of their shares. The Chancery
Court may determine the cost of the appraisal proceedings and allocate the cost
against the dissenting stockholders and Promus as it deems equitable under the
circumstances.

    After the acquisition is complete, any Promus stockholder who has demanded
appraisal in compliance with Section 262 will not be entitled to vote for any
purpose any shares subject to the demand or to receive payment of dividends or
other distributions on the shares, except for dividends or distributions payable
to stockholders of record on a date prior to the effective time of the
acquisition.


    At any time within 60 days after the consummation of the acquisition, any
dissenting stockholder will have the right to withdraw his or her demand for
appraisal and to accept the terms offered in the acquisition. After this period,
the stockholder may withdraw the demand only with the written consent of Promus.
If no petition is filed by any dissenting stockholder within 120 days after the
effective time of the acquisition, Promus stockholders' rights as to appraisal
will cease and dissenting stockholders will be entitled only to receive the
consideration offered pursuant to the merger agreement. These stockholders also
will not be able to elect between cash and Hilton common stock. Instead, they
will receive whatever consideration is available as a result of the proration
procedure discussed in the section titled "The Merger Agreement--Election and
Proration" on page 68.

    THIS IS A DESCRIPTION OF THE TERMS OF THE MERGER AGREEMENT THAT WE BELIEVE
ARE IMPORTANT. HOWEVER, THE DESCRIPTION DOES NOT CONTAIN ALL THE TERMS OF THE
MERGER AGREEMENT. A COPY OF THE MERGER AGREEMENT, AS AMENDED, IS ATTACHED AS
APPENDIX A TO THE JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. WE ENCOURAGE YOU TO READ THE ENTIRE MERGER AGREEMENT.


CLOSING

    The acquisition will become effective at the closing, which will take place
on the date on which the certificate of merger is filed with the Delaware
Secretary of State or at such later time as the certificate of merger specifies.

CONSIDERATION TO BE RECEIVED FOR PROMUS COMMON STOCK IN THE ACQUISITION

    At the effective time, each share of Promus common stock, other than shares
held by dissenting stockholders and shares held by Promus or Hilton, will be
converted at the election of each holder, subject to proration as described
below, to the right to receive either:

    - $38.50 in cash; or

    - not less than 2.9096 shares or more than 3.2158 shares of Hilton common
      stock determined by the exchange ratio.

    Promus stockholders who receive Hilton common stock will receive a number of
shares equal to $38.50 divided by the average Hilton stock price, but in any
event not less than 2.9096 shares or more than 3.2158 shares, for each share of
Promus common stock.

    - If the average Hilton stock price, as described below, is between $11.97
      and $13.23, Promus stockholders who receive Hilton common stock will
      receive for each Promus share a number of Hilton shares equal to $38.50
      divided by the average Hilton stock price.

    - If the average Hilton stock price is greater than $13.23, Promus
      stockholders who receive Hilton common stock will receive 2.9096 Hilton
      shares for each Promus share.

    - If the average Hilton stock price is less than $11.97, Promus stockholders
      who receive Hilton common stock will receive 3.2158 Hilton shares for each
      Promus share.

    The average Hilton stock price is the average of the volume weighted average
per share sales price of Hilton common stock on the NYSE for 20 trading days
selected by lot from the 30 trading days ending on the fifth trading day before
the closing of the acquisition.

    After the effective time, all shares of Promus common stock will cease to be
outstanding and will automatically be canceled.

    Each share of Promus common stock held by Promus as treasury stock or owned
by Hilton or any wholly-owned subsidiary of either company immediately before
the effective time of the acquisition will be canceled without any conversion or
payment.

ELECTION AND PRORATION

    ELECTION


    Promus stockholders who do not exercise their dissenters' appraisal rights
may elect, on a share-by-share basis, to receive $38.50 in cash or shares of
Hilton common stock. This election must be made by completing the form of
election and letter of transmittal distributed to Promus stockholders in a
separate mailing. Promus stockholders making an election must submit their
completed form of election and letter of transmittal as to any or all of their
shares to First Union National Bank, the


                                       68
<PAGE>

exchange agent in this transaction, by 5:00 p.m. on November 29, 1999. Those
stockholders must also include the Promus stock certificates representing the
Promus shares that are the subject of their election.


    Promus stockholders who do any of the following will be deemed to have made
a non-election, which means that the stockholder will receive cash or shares of
Hilton common stock based on the proration method described below:

    - fail to submit a form of election prior to the election deadline;

    - submit and then revoke the forms of election and not re-submit forms of
      election prior to the election deadline; or

    - submit a form of election without corresponding stock certificates or a
      guarantee of delivery.

    Notwithstanding a Promus stockholder's election, the conversion of Promus
common stock is limited as follows:


    - the aggregate number of shares of Promus common stock that may be
      converted into cash in the acquisition is equal to 55% of the number of
      shares of Promus common stock outstanding immediately prior to the
      closing, excluding shares held by Promus, Hilton or any of their wholly-
      owned subsidiaries, less any dissenting shares. We refer to these shares
      as the maximum cash shares; and



    - the aggregate number of shares of Promus common stock that may be
      converted into the right to receive shares of Hilton common stock in the
      acquisition is equal to 45% of the number of shares of Promus common stock
      outstanding immediately prior to the closing excluding shares held by
      Promus, Hilton or any of their wholly-owned subsidiaries.


    PRORATION

    If cash elections are received for more than the maximum cash shares, the
acquisition consideration will be allocated as follows:

    - shares for which a stock election or a non-election has been made will be
      converted into Hilton common stock; and

    - shares for which a cash election has been made will be converted into
      Hilton common stock and cash as follows:

       -- for each cash election, the number of shares of Promus common stock
          covered by the cash election that will receive cash will be the
          product of:

           * the total number of shares covered by the cash election, times

           * a proration fraction, the numerator of which is a number equal to
             the maximum cash shares and the denominator of which is the
             aggregate number of shares of Promus common stock covered by all
             cash elections; and

       -- all remaining shares of Promus common stock covered by a cash election
          will be converted into shares of Hilton common stock.

    If stock elections are received for more than 45% of the outstanding shares
of Promus common stock, the acquisition consideration will be allocated as
follows:

    - shares for which a cash election or a non-election has been made will be
      converted into cash;

                                       69
<PAGE>
    - shares for which a stock election has been made will be converted into
      Hilton common stock and cash as follows:

       -- for each stock election, the number of shares of Promus common stock
          covered by such stock election that will be exchanged into Hilton
          common stock will be the product of:


           * the total number of shares covered by the stock election, times



           * a proration fraction, the numerator of which is a number equal to
             45% of the outstanding shares of Promus common stock (less shares
             owned by Promus, Hilton or their subsidiaries) and the denominator
             of which is the aggregate number of shares of Promus common stock
             covered by all stock elections; and


       -- all remaining shares of Promus common stock covered by a stock
          election will be converted into cash.


    If cash elections are received for less than the maximum cash shares and
stock elections are received for less than 45% of the outstanding shares of
Promus common stock, the acquisition consideration will be allocated as follows:



    - shares for which a cash election has been made will be converted into
      cash;



    - shares for which a stock election has been made will be converted into
      Hilton common stock; and



    - shares for which a non-election has been made will be converted into cash
      and Hilton common stock as follows:



       -- the number of shares of Promus common stock covered by the
          non-election that will receive cash will be the product of:



           * the total number of shares covered by the non-election, times



           * a proration fraction, the numerator of which is the number equal to
             the amount by which the maximum cash shares exceeds the aggregate
             number of shares of Promus common stock covered by all cash
             elections and the denominator of which is the aggregate number of
             shares of Promus common stock covered by all non-elections; and



       -- all remaining shares of Promus common stock covered by a non-election
          will be converted into shares of Hilton common stock.



    The following are three examples of the proration of the acquisition
consideration received by a Promus stockholder who owns 100 shares of Promus
common stock and elects the type of acquisition consideration shown in the
examples. The examples assume there are no dissenting shares.

PROCEDURES FOR EXCHANGE OF PROMUS COMMON STOCK



    At the closing, Hilton will deposit with the exchange agent certificates
representing the shares of Hilton common stock and an estimated amount of the
cash to be paid to Promus stockholders in the acquisition. Each form of election
and letter of transmittal sent to Promus stockholders before closing includes
detailed instructions on how Promus stockholders may exchange their Promus
common stock for the consideration they will receive in the acquisition. After
the closing, the exchange agent will send to former Promus stockholders who
submitted their forms of election and letters of transmittal to the exchange
agent with their Promus share certificates new certificates for the Hilton
common stock, and a check for the cash and any fractional share interests or
dividends or distributions the stockholder is entitled to receive. No interest
will be paid on any cash to be paid pursuant to the acquisition.



    In addition, soon after the acquisition is completed, Hilton will send to
Promus stockholders of record immediately before the closing, other than
dissenting stockholders and stockholders who have previously sent their stock
certificates to the exchange agent, a letter of transmittal instructing the
stockholders on how to exchange their Promus common stock for the consideration
they are entitled to receive in the acquisition.



    Hilton will not pay Promus stockholders entitled to receive Hilton common
stock in the acquisition any dividends or other distributions with respect to
Hilton common stock with a record date occurring after the closing until those
stockholders have properly surrendered their Promus share certificates.


TREATMENT OF FRACTIONAL SHARES

    Holders of Promus common stock will be paid cash instead of any fractional
shares of Hilton common stock they would otherwise receive. The amount of cash
to be received instead of the fractional share will be equal to:

    - a fraction, the numerator of which is the fractional share interest to
      which a holder would otherwise be entitled and the denominator of which is
      the aggregate amount of fractional share interests to which all holders
      would otherwise be entitled, multiplied by


    - the net proceeds from the sale on the NYSE by the exchange agent of any
      excess shares of Hilton common stock received from Hilton by the exchange
      agent but not delivered to Promus stockholders receiving Hilton shares in
      the acquisition.


                                       71
<PAGE>
TREATMENT OF PROMUS EMPLOYEE AND DIRECTOR STOCK OPTIONS


    In general, each outstanding Promus employee and director stock option will
be canceled in accordance with the terms of the plans under which such options
were issued. Payment for each stock option will equal an amount in cash
determined by multiplying:


    - the excess, if any, of $38.50 over the applicable exercise price of such
      Promus stock option by

    - the number of Promus shares such holder could have purchased (assuming
      full vesting of the option) had the holder exercised the option in full
      immediately prior to the effective time.


    If the payment is made at the closing, Promus will pay the holder of the
stock option. If the payment is made after the closing, Hilton will pay the
holder.


TREATMENT OF GE WARRANTS AND OPTIONS

    An affiliate of General Electric Company holds warrants to purchase an
aggregate of 262,753 shares of Promus common stock. At the effective time of the
acquisition, Hilton will assume each outstanding GE warrant such that each
holder of a GE warrant will have the right to receive the same number of shares
of Hilton common stock as the holder would have been entitled to receive in the
acquisition if the holder had exercised its GE warrants in full immediately
prior to the effective time, had elected to receive Hilton common stock in the
acquisition and the stock consideration was not subject to proration.

    Affiliates of General Electric hold options to purchase an aggregate of
22,500 shares of Promus common stock. At the effective time of the acquisition,
Hilton will assume each of these outstanding GE options such that each holder
will have the right to receive the same number of shares of Hilton common stock
as the holder would have been entitled to receive in the acquisition if the
holder had exercised its GE options in full immediately prior to the effective
time, had elected to receive common stock in the acquisition and the stock
consideration was not subject to proration.

REGISTRATION AND LISTING OF HILTON COMMON STOCK

    Hilton has agreed to use its reasonable best efforts to register the shares
of Hilton common stock to be issued as consideration in the acquisition under
the Securities Act and to cause the shares to be listed on the NYSE. The
registration and listing are conditions to the obligations of Hilton and Promus
to consummate the acquisition. Hilton has registered the issuance of such shares
in the acquisition under the Securities Act pursuant to a registration statement
which the SEC has declared effective.

REPRESENTATIONS AND WARRANTIES

    Promus and Hilton made certain customary representations and warranties to
each other, including as to:

action outside the parameters specified in the merger agreement, such as:

    - changing its accounting practices or its fiscal year;

    - engaging in a transaction with any affiliate, director or officer of
      Hilton, except on an arms' length basis; or

      1999 bonus plan to all employees who, as of September 3, 1999,

      directors chosen by Hilton;

    - to use its reasonable best efforts to cause the Hilton stock issuable in
      the acquisition to be listed on the NYSE and Pacific Stock Exchange;

    - not to take any action that, in the opinion of counsel, would cause the
      distribution by Hilton of Park Place to fail to be qualified as a tax-free
      transaction under Section 355(a) and (c) of the Internal Revenue Code;

    - to use its best efforts to obtain financing for the cash consideration and
      the other amounts contemplated by the merger agreement;

      agreement.


                                       74
<PAGE>
CONDITIONS TO THE COMPLETION OF THE ACQUISITION

    Hilton and Promus will complete the acquisition only if the conditions
specified in the merger agreement are either satisfied or waived. The conditions
are:

    - the Hilton stockholders and the Promus stockholders approve the
      acquisition;


    - there is no law or court order prohibiting the acquisition;


    - the stock issuable in the acquisition is authorized for listing on the
      NYSE;

    - each of Hilton and Promus has performed in all material respects all of
      their respective obligations under the merger agreement;

      agreement remain accurate in all material respects, with such exceptions
      as would not reasonably be expected to have a material adverse effect.
      Material adverse effect excludes any effect resulting from changes in the
      hotel industry or a geographic region generally, changes in general
      economic or business conditions or the merger agreement;

    - if the forward merger structure is used, Hilton and Promus receive legal
      opinions as to tax matters relating to the acquisition; and

    - funds are available to Hilton in an amount sufficient to pay the cash
      consideration contemplated by the acquisition, to refinance certain
      existing indebtedness of Promus and to pay related fees and expenses,
      except that this condition will not apply if Hilton is in material breach
      of the financing-related provisions of the merger agreement or any
      provisions of Hilton's financing agreements, other than breaches of
      representations and warranties in the financing agreements attributable
      solely to facts and circumstances relating to Promus.

TERMINATION OF THE MERGER AGREEMENT

    Both companies may mutually agree to terminate the merger agreement at any
time without completing the acquisition. Either company may terminate the merger
agreement if:


    (1) the acquisition is not completed by March 31, 2000, unless funds are not
       available to Hilton because of a "Year 2000 problem" that causes a
       material adverse change in the financial markets, in which case the
       deadline is extended to April 30, 2000. Neither Hilton nor Promus may
       terminate the merger agreement on this basis, however, if that company's
       breach of the merger agreement results in the acquisition not being
       completed by the applicable deadline;


    (2) a court or other governmental authority issues a final, non-appealable
       order prohibiting the acquisition, or any law makes the acquisition
       illegal. Neither Hilton nor Promus may terminate the merger agreement on
       this basis, however, if its breach of the merger agreement results in the
       imposition of the order or the application of the law or regulation to
       the acquisition; or

    (3) the Hilton stockholders or the Promus stockholders do not approve the
       acquisition.

    In addition, Hilton may terminate the merger agreement if:

    (4) any person or group of persons acting in concert, other than Hilton or
       its affiliates, acquires beneficial ownership of more than 50% of the
       shares of Promus common stock;

    (5) the Promus board of directors withdraws or amends in a manner adverse to
       Hilton its recommendation of the acquisition and approves a superior
       proposal; or

    (6) Promus enters into or announces its intention to enter into an agreement
       with a third party based on a superior proposal.

                                       75
<PAGE>
    Furthermore, Promus may terminate the merger agreement if:

    (7) the Promus board of directors approves a superior, unsolicited proposal
       or withdraws or amends in a manner adverse to Hilton its recommendation
       of the acquisition, so long as Promus has complied with the
       non-solicitation, board recommendation, notice and termination fee
       provisions of the merger agreement and Hilton has not offered adjustments
       to the merger agreement that would allow the Promus board of directors to
       recommend the acquisition by Hilton; or

    (8) the Hilton board of directors withdraws or amends in a manner adverse to
       Promus its recommendation to approve the acquisition.

TERMINATION FEES AND EXPENSES

    Promus has agreed to pay Hilton a termination fee of $75 million if:

    - the merger agreement is terminated in the circumstances described in
      paragraphs (4), (5), (6) or (7) above;

    - the merger agreement is terminated by Hilton under the circumstances
      described in paragraph (1) above and:

       - prior to the termination, a third party has made a proposal for an
         alternative transaction with Promus and after the proposal is made,
         Promus materially and intentionally breaches any of its material
         obligations under the merger agreement; and

       - within 12 months of the termination, Promus enters into an agreement
         for or consummates an alternative transaction with any third party; or

    - the merger agreement is terminated by Hilton because the Promus
      stockholders do not approve the merger agreement and

       - any person or group of persons acting in concert other than Hilton or
         its affiliates acquires beneficial ownership of 25% or more of the
         outstanding shares of Promus common stock and within 12 months of
         termination of the merger agreement Promus enters into an agreement for
         an alternative transaction with that person or group; or

       - prior to the Promus stockholder meeting, a third party has made a
         proposal for an alternative transaction with Promus and within 12
         months of termination of the merger agreement, Promus enters into an
         agreement for or consummates an alternative transaction with any third
         party.

    Hilton has agreed to pay Promus a termination fee of $150 million if Hilton
or Promus terminates the merger agreement in the circumstances described in
paragraph (1) above, and all of the following have occurred:

    - funds have not been made available to Hilton in an amount sufficient to
      pay the cash consideration, to refinance certain Promus indebtedness and
      to pay merger related fees and expenses;

    - other conditions to the completion of the acquisition specified in the
      merger agreement have been satisfied; and

    - the unavailability of the funds was not due to a breach of any
      representation or warranty in Hilton's financing agreements that is
      attributable solely to facts and circumstances relating to Promus.

                                       76
<PAGE>
NO SOLICITATION; COVENANT TO RECOMMEND

    The merger agreement prevents Promus from negotiating or otherwise engaging
in discussions with, or furnishing information to, a third party regarding an
acquisition transaction with Promus unless:

    - Promus has received an unsolicited proposal for the transaction from that
      third party;

    - Promus has notified Hilton about the proposal;

    - the Promus board of directors determines in good faith that, based on the
      terms and conditions contained in the proposal, the proposal could
      reasonably be expected to constitute a superior proposal, as described
      below; and

    - the third party executes a confidentiality agreement with terms
      substantially similar to those contained in the confidentiality agreement
      between Hilton and Promus.

    The Promus board of directors has agreed to recommend the approval and
adoption of the merger agreement and the acquisition to Promus stockholders.
However, the Promus board is permitted to withdraw, or modify in a manner
adverse to Hilton, its recommendation if:

    - Promus has received an unsolicited proposal from a third party regarding
      an acquisition transaction with Promus which the Promus board determines
      in good faith would, if consummated, constitute a superior proposal;

    - the Promus board determines in good faith, on the basis of advice of
      outside legal counsel, that it must withdraw, or modify in a manner
      adverse to Hilton, its recommendation in order to comply with its
      fiduciary duties under applicable law;

    - Promus delivers to Hilton a prior written notice advising Hilton that it
      intends to withdraw, or modify in a manner adverse to Hilton, its
      recommendation; and

    - Promus concurrently terminates the merger agreement and pays the
      $75 million termination fee.

    A superior proposal is a bona fide written proposal from a third party for:

    - a business combination transaction involving Promus; or

    - the acquisition of more than 50% of the voting securities of Promus or a
      substantial portion of Promus' assets,

which the Promus board of directors concludes in good faith, after consultation
with its financial advisors and legal counsel, taking into account all legal,
financial, regulatory and other aspects of the proposal including the nature and
sufficiency of financing for the proposal and the person making the proposal:

    - would, if consummated, result in a transaction that is more favorable to
      Promus stockholders from a financial point of view than the transactions
      contemplated by the merger agreement; and

    - is reasonably likely to be completed.

AMENDMENT OR WAIVER OF THE MERGER AGREEMENT

    The parties may amend the merger agreement or waive its terms and conditions
before the effective time, but, after Promus' stockholders have approved the
merger agreement, the parties may not amend the merger agreement in a manner
that would reduce or change the kind of consideration Promus stockholders will
receive in the acquisition.

                          HILTON AFTER THE ACQUISITION

MANAGEMENT

    DIRECTORS


    In connection with the acquisition, Hilton has agreed to appoint two of
Promus' current directors to the Hilton board. Hilton is asking its stockholders
to approve at the special meeting an amendment to the Hilton by-laws to provide
for a board of directors comprised of between 10 and 20 members. See "Amendment
to Hilton's By-laws" on page 93. If the amendment is approved, Hilton intends to
increase the size of its board from 12 to 14, and to appoint two of the current
Promus directors chosen by Hilton to fill the vacancies. If the by-law amendment
is not approved at the special meeting, Hilton expects to appoint two of Promus'
current directors to replace two of Hilton's current directors. Hilton has not
yet chosen which two of the current Promus directors it will appoint. More
information about each of the members of Promus' board of directors is included
in Promus' filings with the SEC. For information on how you can obtain copies of
these filings, please see the section entitled "Where You Can Find More
Information" on page 94.



    Following the acquisition, the directors of PRH Acquisition on the closing
date will be the directors of the surviving corporation. These directors are
Stephen F. Bollenbach, Thomas E. Gallagher and Matthew J. Hart. More information
about Messrs. Bollenbach, Gallagher and Hart is included in Hilton's filings
with the SEC. For information on how you can obtain copies of these filings,
please see the section entitled "Where You Can Find More Information" on
page 94.


    EXECUTIVE OFFICERS


    The composition of Hilton's management is not expected to change materially
as a result of the acquisition but certain officers of Promus may become
officers of Hilton in connection with the integration of management following
the acquisition. More information about each of Hilton's executive officers is
included in Hilton's filings with the SEC. For information on how you can obtain
copies of these filings, please see the section entitled "Where You Can Find
More Information" on page 94. Hilton may enter into retention or other
arrangements with Promus officers who are employed by the surviving corporation
following the acquisition.



    The officers of Promus at the effective time will be the officers of the
surviving corporation, a wholly-owned subsidiary of Hilton. Hilton intends to
appoint new officers of the surviving corporation immediately after the closing
of the acquisition. These new officers will be selected from Hilton's and
Promus' officers. More information about each of Hilton's and Promus' executive
officers is included in Hilton's and Promus' respective filings with the SEC.
For information on how you can obtain copies of these filings, please see the
section entitled "Where You Can Find More Information" on page 94.


HILTON CAPITAL STOCK

    As of September 3, 1999, Hilton was authorized to issue 400,000,000 shares
of Hilton common stock, of which 254,976,661 shares were issued, including
treasury shares of 10,337,356, and 24,832,700 shares of Hilton preferred stock,
of which no shares have been issued. If the Hilton stockholders approve the
amendment to Hilton's certificate of incorporation and the acquisition is
completed, then Hilton will be authorized to issue 500,000,000 shares of Hilton
common stock.

    Each share of Hilton common stock entitles the holder to one vote on matters
submitted to a vote of the stockholders, and, subject to the prior preferences
of the Hilton preferred stock, if issued, a pro rata share of assets remaining
available for distribution to stockholders upon a liquidation of Hilton.
Dividends may be paid to the holders of the Hilton common stock when and if
declared by Hilton's board of directors out of funds legally available therefor,
but any dividend that exceeds $0.02 per share

                                       78
<PAGE>
per quarter may be declared only after consummation of the acquisition. Hilton
has in the past paid cash dividends on its common stock. Any determination to
pay cash dividends following the effective time will be at the discretion of
Hilton's board of directors and will depend upon the earnings of Hilton, its
financial condition, capital requirements and other factors as the board of
directors may deem relevant. Hilton common stock is not convertible or
redeemable and has no preemptive rights.


    After giving effect to the acquisition, the former holders of Promus common
stock who receive Hilton common stock in the acquisition will hold approximately
30% of the outstanding shares of Hilton common stock. This percentage is based
on the number of shares of Hilton common stock and Promus common stock
outstanding as of October 15, 1999.


DESCRIPTION OF HILTON'S BANK CREDIT FACILITIES

    In connection with the acquisition, Hilton has entered into a fully
underwritten commitment for a new $2 billion unsecured senior credit facility
with Bank of America N.A.

    Bank of America's commitment is subject to customary closing conditions,
including no occurrence of a material adverse change in or disruption of
conditions in the financial banking or capital markets and the absence of any
material adverse change in Hilton's and Promus' pro forma combined condition,
business or assets since December 31, 1998. In connection with the new credit
facility, Hilton will obtain an amendment to its existing credit facility to
permit debt incurred under the new credit facility to be in compliance with
Hilton's leverage ratio covenant.

    The existing credit facility provides for borrowings up to $1.75 billion,
and the new credit facility will provide for borrowings up to an additional
$2.0 billion. Proceeds of borrowings under the bank credit facilities will be
used to consummate the acquisition, refinance certain existing debt of Promus,
pay related fees and expenses and, after completion of the acquisition, for
general corporate purposes of Hilton.

    Loans under the bank credit facilities will bear interest at a rate equal to
LIBOR or, at Hilton's option, Bank of America's prime rate, in either case plus
a margin determined by reference to Hilton's long-term senior unsecured debt
ratings or to the ratio of its consolidated total debt to its consolidated
EBITDA.

    The existing credit facility matures on October 18, 2001 and may be extended
for successive one-year periods at the request of Hilton with the prior written
consent of the lenders. The new credit facility will consist of a $1.5 billion
five-year revolver and $500 million 364-day revolver. Hilton expects that the
maturity dates of the new credit facility will be extendible on substantially
the same terms as are applicable to the existing credit facility.

    The bank credit facilities will contain customary affirmative and negative
covenants, substantially consistent with Hilton's existing credit facility,
including covenants that restrict, subject to specified exceptions, the
incurrence of liens and consolidations, mergers and sales of assets. In
addition, the bank credit facilities will require that Hilton maintain
compliance with specified financial covenants, including a maximum consolidated
total debt to consolidated EBITDA ratio and a minimum consolidated interest
coverage ratio. The bank credit facilities will contain customary events of
default substantially consistent with Hilton's existing credit facility,
including payment defaults, breaches of representations and warranties, covenant
defaults, certain events of bankruptcy and insolvency and cross defaults to
other material indebtedness.

INDEPENDENT ACCOUNTANTS

    Arthur Andersen LLP will remain the independent accountants for Hilton after
the acquisition. Arthur Andersen LLP currently also serves as the independent
accountants for Promus.

                HILTON UNAUDITED PRO FORMA FINANCIAL STATEMENTS

    The unaudited pro forma statements of income and balance sheet of Hilton
illustrate the estimated effects of the acquisition. The unaudited pro forma
balance sheet of Hilton as of June 30, 1999 presents the financial position of
Hilton as if the acquisition had been completed as of such date. The unaudited
pro forma income statements of Hilton for the six month period ended June 30,
1999 and the year ended December 31, 1998 present the results of operations of
Hilton as if the acquisition had been completed as of January 1, 1998.


    The unaudited pro forma statements of income and balance sheet of Hilton are
based upon the historical consolidated financial statements of Hilton and Promus
contained in each company's Annual Report on Form 10-K for the year ended
December 31, 1998 and Quarterly Report on Form 10-Q for the quarter ended
June 30, 1999, each of which is incorporated by reference in this joint proxy
statement/prospectus, and should be read in conjunction with those consolidated
financial statements and related notes. See "Where You Can Find More
Information" on page 94.


    The unaudited pro forma statements of income of Hilton for the six months
ended June 30, 1999 and the year ended December 31, 1998 give effect to the
acquisition of Promus by applying the purchase method of accounting and certain
adjustments that are directly attributable to the acquisition as if the
transaction was consummated as of January 1, 1998.

    The unaudited pro forma balance sheet of Hilton presents the combined
financial position of Hilton and Promus as of June 30, 1999. The unaudited pro
forma balance sheet reflects the acquisition of Promus applying the purchase
method of accounting and certain adjustments that are directly attributable to
the acquisition. Such data further assume that the transactions described above
were consummated as of June 30, 1999.

    The pro forma financial data of Hilton does not purport to represent what
the financial position or results of operations of Hilton would have been if the
acquisition had in fact been consummated on such date or at the beginning of the
period indicated or to project the financial position or results of operations
for any future date or period. The pro forma adjustments are based upon
available information and upon certain assumptions that Hilton and Promus
management believe are reasonable. In the opinion of Hilton management, all
adjustments necessary to present fairly the unaudited pro forma financial
information have been made.

    For the purposes of preparing the financial statements of Hilton, management
will undertake a study to establish the fair value of the acquired assets and
liabilities of Promus. The allocation of the purchase price to the assets and
liabilities acquired reflected in this pro forma financial data is preliminary.
Accordingly, the actual financial position and results of operations may differ
from these pro forma amounts.

                           HILTON HOTELS CORPORATION

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

The following table sets forth the estimated determination and allocation of the
purchase price of Promus. In the acquisition, Promus stockholders will receive,
at their election, for each share of Promus common stock either:

    - $38.50 in cash; or

    - not less than 2.9096 shares or more than 3.2158 shares of Hilton common
      stock determined as described below.


    Each Promus stockholder's election may be subject to proration depending on
the consideration other stockholders elect to receive in the acquisition. The
proration will ensure that 55% of the outstanding Promus shares will be
converted into cash, while the remaining 45% will be converted into Hilton
common stock.


    Promus stockholders who receive Hilton common stock will receive a number of
shares equal to $38.50 divided by the average Hilton stock price, but in any
event not less than 2.9096 shares or more than 3.2158 shares, for each share of
Promus common stock.

    - If the average Hilton stock price, as described below, is between $11.97
      and $13.23, Promus stockholders who receive Hilton common stock will
      receive for each Promus share a number of Hilton shares equal to $38.50
      divided by the average Hilton stock price.

    - If the average Hilton stock price is greater than $13.23, Promus
      stockholders who receive Hilton common stock will receive 2.9096 Hilton
      shares for each Promus share.

    - If the average Hilton stock price is less than $11.97, Promus stockholders
      who receive Hilton common stock will receive 3.2158 Hilton shares for each
      Promus share.

    The average Hilton stock price is the average of the volume weighted average
per share sales price of Hilton common stock on the NYSE for 20 trading days
selected by lot from the 30 trading days ending on the fifth trading day before
the closing of the acquisition.


    For purposes of the pro forma financial statements, an exchange ratio of
3.2158 has been computed based on the October 18, 1999 Hilton common stock
closing price of $9.00. The actual exchange ratio will be computed over the time
period described above. For a more detailed discussion of the exchange ratio,
see "The Merger Agreement--Consideration to be Received for Promus Common Stock
in the Acquisition" on page 68.

 (1) Pro forma results do not reflect any operational efficiencies, cost savings
     associated with greater economies of scale or revenue enhancement
     opportunities which Hilton expects to achieve after the acquisition. Hilton
     expects to realize pre-tax annual revenue enhancements and pre-tax cost
     savings, including operating efficiencies, totaling approximately
     $90 million upon full integration of Promus. Hilton expects to realize
     approximately $55 million of benefits in 2000, and the entire $90 million
     of benefits beginning in 2001. However, the estimated benefits are based on
     projections and assumptions, not actual experiences. As a result, Hilton's
     ability to realize these benefits could be adversely impacted by
     difficulties integrating Promus into Hilton, the inability to achieve
     certain economies of scale or other risks associated with achieving
     projected revenues and cost savings. Hilton cannot assure you that these
     revenue enhancements and cost savings will be achieved.


 (2) There are no significant adjustments required to the historical financial
     data of Promus to conform to the accounting policies of Hilton. Certain
     reclassifications have been made to the historical balances of Hilton and
     Promus to conform the financial presentation of Hilton and Promus. Hilton's
     rooms, food and beverage and other revenue and expenses have been
     reclassified as owned hotel revenues and expenses and depreciation and
     amortization expense has been segregated. Promus' general and
     administrative expenses have been reclassified as corporate and other
     operating expenses. These reclassifications have no effect on historical or
     pro forma operating income, income from continuing operations or earnings
     per share.

 (3) To adjust depreciation and amortization to reflect the revaluation of
     acquired property and equipment, equity investments, identifiable
     intangible assets and goodwill.

 (4) To record the estimated increase in interest expense and long-term debt
     associated with

       - the cash portion of the acquisition consideration totaling $1,666
         million,

       - estimated change of control and severance costs relating to certain
         Promus employees, and

       - estimated direct acquisition costs of Hilton and Promus.

     The estimated increase in interest expense for these items is computed at
     an assumed weighted average borrowing rate of 6.29% for the six months
     ended June 30, 1999 and 6.84% for the year ended December 31, 1998,
     representing 30-day LIBOR plus 125 basis points. Change of control costs
     include contractual payments for certain Promus executives, including
     option cash-outs. Severance costs include termination benefits related to
     the elimination of duplicative corporate office and operational support
     functions. Direct acquisition costs include investment advisor fees and
     bank financing costs. Each 1/8 percent change in the rate on this financing
     would result in a change in interest expense of $1 million for the six
     months ended June 30, 1999 and $2 million for the year ended December 31,
     1998.

     The pro forma adjustment to interest expense also includes amortization of
     estimated debt issuance costs totaling $2 million for the six months ended
     June 30, 1999 and $5 million for the year ended December 31, 1998.

 (5) To record the tax effect of the pro forma adjustments to depreciation and
     amortization expense, cost reductions associated with estimated operational
     efficiencies, and interest expense. The amortization of goodwill is not tax
     effected for financial accounting or tax purposes.

 (6) To record the deferred tax effect of the pro forma balance sheet
     adjustments, primarily related to property and equipment, equity
     investments, identifiable intangible assets, severance and acquisition
     costs.

 (7) To increase Promus' equity hotel investments to estimated fair market
     value.

 (8) To increase Promus' property and equipment to estimated fair market value.

 (9) To value Promus' identifiable intangible assets at fair market value and
     reflect the excess purchase price over the estimated fair value of assets
     acquired and liabilities assumed. Identifiable intangible assets include
     management and franchise contracts, lease agreements and acquired brands
     and trademarks, and are amortized over a weighted average life of 23 years.
     Goodwill is amortized over 40 years.

 (10) To record deferred costs associated with financing the cash portion of the
      acquisition, net of deferred financing costs of Promus not valued in
      purchase accounting.

 (11) The net increase in stockholders' equity results from:


       - the issuance of an estimated $1,025 million in Hilton equity
         consideration in connection with the acquisition and


       - the elimination of Promus' historical equity.

                            INFORMATION ABOUT HILTON


    The following is a brief description of Hilton's business. Additional
information regarding Hilton is contained in its filings with the SEC. For
information on how you can obtain copies of such filings, please see the section
entitled "Where You Can Find More Information" on page 94 of this joint proxy
statement/prospectus.



    Hilton is primarily engaged in the ownership, management and franchising of
hotels. As of September 30, 1999, all of these properties were located in the
United States, with the exception of 19 hotels which are located in 10 foreign
countries.



    On September 30, 1999, Hilton owned an interest in or leased and operated 43
hotels and managed 23 hotels owned by others. In addition, 217 hotels were
operated under the Hilton, Hilton Garden Inn and Hilton Suites names by third
parties pursuant to franchises granted by Hilton. Hilton operates vacation
ownership resorts under the Hilton Grand Vacations name. Hilton is also engaged
in various other activities related to the operation of hotels.


    Hilton's principal executive offices are located at 9336 Civic Center Drive,
Beverly Hills, California 90210, and its telephone number is (310) 278-4321.

                          HILTON'S RECENT DEVELOPMENTS


    Since the filing of Hilton's Quarterly Report on Form 10-Q for the period
ended June 30, 1999, Hilton has opened the new 600-room Hilton Boston Logan
Airport, located in the center of Boston's Logan Airport, and acquired a 100%
ownership interest in the Hilton Minneapolis & Towers, which has been managed by
Hilton since 1992.


                            INFORMATION ABOUT PROMUS


    The following is a brief description of Promus' business. Additional
information regarding Promus is contained in its filings with the SEC. For
information on how you can obtain copies of such filings, please see the section
entitled "Where You Can Find More Information" on page 94.


    Through its wholly-owned subsidiaries, Promus franchises and manages hotels
with the following brands: Doubletree, Doubletree Guest Suites, Club Hotel by
Doubletree, Embassy Suites, Hampton Inn, Hampton Inn & Suites, Homewood Suites
and Red Lion. Promus may also own all or a portion of these hotels or lease
these hotels from others. In addition, Promus leases and manages some hotels
that are not Promus-branded.


    As of September 30, 1999, Promus franchised 1,112 hotels and operated 331
hotels, of which 184 were managed for third party owners, 51 were wholly-owned,
23 were partially-owned through joint ventures and 73 were leased from third
parties. These hotels are located in all 50 states, the District of Columbia,
Puerto Rico, the U.S. Virgin Islands and six foreign countries. Promus also
operates and franchises vacation interval ownership systems under the Embassy
Vacation Resort and Hampton Vacation Resort names.


    Promus' principal executive offices are located at 755 Crossover Lane,
Memphis, Tennessee, 38117, and its telephone number is (901) 374-5000.

                          PROMUS' RECENT DEVELOPMENTS


    In the third quarter of 1999, Promus identified 26 owned hotels to be sold
as part of a plan to reduce ownership of real estate. During September 1999,
Promus closed on sales of 14 of these hotels. The aggregate sales proceeds for
these hotels was approximately $135 million, of which $27 million was received
in the form of a note with a one year maturity. The total net book value for the
14 hotels was $81 million and the total gain on the sales was approximately $46
million. A portion of the gain will be


                                       88
<PAGE>

recognized on the installment method as the note receivable is collected. Promus
signed franchise agreements for all of the sold hotels and will retain
management agreements for four of these hotels.


    Promus is in negotiations with potential buyers or is actively marketing the
12 remaining hotels and expects these hotels to be sold within one year. For two
of these hotels, Promus recorded a write-down in the third quarter of
approximately $17 million to adjust the carrying value to estimated net
realizable value. After consideration of this write down, the total net book
value for the 12 hotels is approximately $95 million and will be reported in
Promus' September 30, 1999 consolidated balance sheet as assets held for sale.

                        COMPARISON OF STOCKHOLDER RIGHTS

    THIS SECTION OF THE JOINT PROXY STATEMENT/PROSPECTUS DESCRIBES CERTAIN
DIFFERENCES BETWEEN THE RIGHTS OF HOLDERS OF HILTON COMMON STOCK AND PROMUS
COMMON STOCK. WHILE WE BELIEVE THAT THIS DESCRIPTION COVERS THE IMPORTANT
DIFFERENCES BETWEEN THE TWO STOCKS, IT MAY NOT CONTAIN ALL OF THE INFORMATION
THAT IS IMPORTANT TO PROMUS STOCKHOLDERS. PROMUS STOCKHOLDERS SHOULD CAREFULLY
READ THIS ENTIRE DOCUMENT AND THE OTHER DOCUMENTS THAT WE REFER TO FOR A MORE
COMPLETE UNDERSTANDING OF THE DIFFERENCES BETWEEN BEING A STOCKHOLDER OF HILTON
AND BEING A STOCKHOLDER OF PROMUS.

    The rights of Promus stockholders are governed by Promus' restated
certificate of incorporation, as currently in effect, and Promus' amended and
restated by-laws. After completion of the acquisition, Promus stockholders may
become stockholders of Hilton. As a Hilton stockholder, your rights will be
governed by Hilton's restated certificate of incorporation and Hilton's by-laws,
each as currently in effect or as proposed to be amended as described in this
joint proxy statement/prospectus. Each of Hilton and Promus is incorporated
under the laws of the State of Delaware and, accordingly, the rights of Promus
stockholders will continue to be governed by the Delaware General Corporation
Law after completion of the acquisition.

CLASSES OF COMMON STOCK OF HILTON AND PROMUS

    We each have one class of common stock issued and outstanding. Holders of
Hilton common stock and holders of Promus common stock are each entitled to one
vote for each share held. Neither of our certificates of incorporation permits
our respective stockholders to cumulate votes at any election of directors.
However, Hilton's by-laws provide that, except where a date shall have been
fixed as a stockholders record date for determination of the shares of Hilton
common stock entitled to vote, no share of stock that was transferred within 20
days prior to any election of directors may be voted at such election.

CLASSIFIED BOARD OF DIRECTORS

    A classified board of directors is one with respect to which a certain
number of directors, but not necessarily all, are elected on a rotating basis
each year. Delaware law permits, but does not require, a classified board of
directors, pursuant to which the directors can be divided into as many as three
classes with staggered terms of office, with only one class of directors
standing for election each year. Each of our certificates of incorporation calls
for a division of each of our respective boards of directors into three classes,
as nearly equal in size as possible, with one class being elected annually and
with each director elected for a term of three years.

REMOVAL OF DIRECTORS

    Any director or the entire board of Promus may be removed only for cause by
the holders of a majority of the shares of Promus stock entitled to vote
generally in the election of directors, voting together as a single class.

                                       89
<PAGE>
    Hilton's certificate of incorporation provides that any director of Hilton
may be removed with or without cause only by the affirmative vote of the holders
of 75% of the voting power of all shares of Hilton stock entitled to vote
generally in the election of directors, voting together as a single class.

FILLING VACANCIES ON THE BOARD OF DIRECTORS

    Any newly created directorships or vacancies in either of our boards of
directors, resulting from any increase in the number of authorized directors or
death, resignation, disqualification, removal or other cause, may be filled
solely by the vote of a majority of the remaining members of such board of
directors, even though less than a quorum, or in the case of Promus, by a sole
remaining director, subject to the rights of holders of any outstanding series
of preferred stock. No decreases in the number of directors on either of our
respective boards of directors may shorten the term of any director then in
office.

LIMITS ON STOCKHOLDER ACTION BY WRITTEN CONSENT

    Both Promus stockholders and Hilton stockholders may take action only at
annual or special meetings of stockholders, and they may not take action by
written consent.

ABILITY TO CALL SPECIAL MEETINGS

    Promus' certificate of incorporation provides that only a majority of its
board of directors, the chairman of the board of directors or the president may
call a special meeting of the stockholders.

    Hilton's certificate of incorporation provides that special meetings of the
stockholders may be called only by the chairman of the board or by the board of
directors pursuant to a resolution approved by a majority of the entire board of
directors.

ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND PROPOSALS

    Promus' by-laws provide that to be timely, a stockholder's notice of
nomination of a director or other proposed business must be received not fewer
than 60 nor more than 90 calendar days before the annual meeting. If the public
announcement of such meeting is not made at least 70 days before the date of
such meeting, the stockholder must make the request no later than 10 calendar
days after the announcement of the meeting.

    Hilton's by-laws provide that a stockholder's notice of a nomination of a
director or other proposed business to be brought before an annual meeting must
be received by the secretary not fewer than 60 calendar days prior to the
meeting.

PREFERRED STOCK

    Both of our certificates of incorporation provide that our boards of
directors are authorized to provide for the issuance of shares of preferred
stock in one or more series, and to fix the designations, powers, preferences
and rights of the shares of each series and any qualifications, limitations or
restrictions on such shares.

AMENDMENT OF CERTIFICATE OF INCORPORATION AND BY-LAWS

    Under Delaware law, a certificate of incorporation of a Delaware corporation
may be amended by approval of the board of directors of the corporation and the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote for the amendment, unless the corporation's certificate of incorporation
requires a higher vote. Stockholders entitled to vote have the power to adopt,
amend or repeal by-laws. In addition, a corporation may, in its certificate of
incorporation,

                                       90
<PAGE>
confer that power upon the board of directors. The stockholders always have the
right to adopt, amend or repeal by-laws, even though the board of directors may
also be delegated such power.

    Promus' certificate of incorporation provides that the affirmative vote of
the holders of at least 75% of the shares of Promus stock entitled to vote
generally in the election of directors, voting together as a single class, is
required to amend Promus' by-laws or, in certain circumstances, to amend the
business combination provision of Promus' certificate of incorporation.

    Hilton's certificate of incorporation provides that the affirmative vote of
the holders of at least 75% of the shares of Hilton stock entitled to vote
generally in the election of directors, voting together as a single class, is
required to amend any of the following provisions of Hilton's certificate of
incorporation, among others:

    - the number, election and terms of directors;

    - nominating procedures;

    - the bringing of stockholder business;

    - removal of directors;

    - filling of vacancies;

    - procedures to amend the by-laws; and

    - procedures to call a special meeting of Hilton's stockholders.

DELAWARE ANTI-TAKEOVER STATUTES

    We are both subject to Section 203 of the Delaware General Corporation Law,
which, under certain circumstances, may make the consummation of various
business transactions by "Interested Stockholders," as defined in Section 203,
with either of us more difficult for a three-year period from the time that the
stockholder becomes an "Interested Stockholder." Under Delaware law, a
corporation may elect in its certificate of incorporation or by-laws not to be
governed by Section 203. Neither Hilton nor Promus has done so.

    Hilton's certificate of incorporation requires that mergers, significant
asset sales, significant stock issuances and other significant transactions with
any entity that owns, directly or indirectly, 10% or more of Hilton's voting
stock be approved by the affirmative vote of at least 75% of the then
outstanding capital stock of Hilton entitled to vote generally in the election
of directors, voting together as a single class. This provision does not apply
if either of the following conditions is satisfied, in which case only the
affirmative vote of a majority of the Hilton voting stock is required for
approval: (i) the transaction is approved by a majority of disinterested
directors of Hilton or (ii) certain enumerated price and procedural requirements
are satisfied.

    Promus' certificate of incorporation requires that acquisitions, mergers,
significant asset sales, significant stock issuances and other significant
transactions with any entity that owns, directly or indirectly, or publicly
discloses a plan to own 10% or more of Promus' voting stock be approved by the
affirmative vote of at least 75% of the then outstanding Promus stock entitled
to vote generally in the election of directors, voting together as single class,
and by a majority of the then outstanding Promus voting stock not held
beneficially by such 10% stockholder. This provision does not apply if either of
the following conditions is satisfied, in which case only the affirmative vote
of a majority of the Promus voting stock is required for approval:

    - the transaction is approved by a majority of directors of Promus who are
      not affiliates of the 10% stockholder and were members of Promus' board of
      directors prior to the time that the 10% stockholder acquired 10% or more
      Promus' voting stock, or

                                       91
<PAGE>
    - certain enumerated price and procedural requirements are satisfied.

LIMITATION OF LIABILITY OF DIRECTORS

    The Delaware General Corporation Law permits a corporation to include a
provision in its certificate of incorporation eliminating or limiting the
personal liability of a director or officer to the corporation or its
stockholders for damages for a breach of the director's fiduciary duty, subject
to certain limitations.


    Each of our respective certificates of incorporation includes a provision
eliminating personal liability of our respective directors to each of us or to
our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability for any of the following:


    - any breach of the director's duty of loyalty to the company or its
      stockholders;

    - any acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

    - under Section 174 of the Delaware General Corporation Law regarding
      unlawful payment of dividends or unlawful stock purchases or redemptions;
      or

    - any transaction from which the director derived an improper personal
      benefit.

    In addition, Promus' certificate of incorporation provides that if the
Delaware General Corporation Law is amended to authorize corporate action
further limiting or eliminating the personal liability of directors, then the
liability of each Promus director will be limited or eliminated to the fullest
extent permitted by the Delaware General Corporation Law as so amended from time
to time.

    While these provisions provide directors with protection from awards for
monetary damages for breaches of their fiduciary duties, they do not eliminate
that duty. Accordingly, these provisions will have no effect on the availability
of equitable remedies such as an injunction or recission based on a director's
breach of his or her fiduciary duty.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Delaware General Corporation Law permits a corporation to indemnify
officers and directors for actions taken in good faith and in a manner they
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and with respect to any criminal action, which they had no
reasonable cause to believe was unlawful.

    Both of our respective certificates of incorporation provide that any person
who was or is a party or is threatened to be made a party to or is involved in
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, other than an action by or in right
of the corporation, because that person is or was a director or officer, or is
or was serving at the request of either of us as a director or officer of
another corporation or of a partnership, joint venture, trust or other
enterprise, will be indemnified against expenses, including attorney's fees,
judgments, fines and amounts paid in a settlement, and held harmless by each of
us to the fullest extent permitted by the Delaware General Corporation Law. In
the case of actions, suits or proceedings by or in right of the corporation,
both of our certificates of incorporation provide that an otherwise indemnified
person will be indemnified only for expenses, including attorneys' fees, and
only if such person was not adjudged to be liable to the corporation, subject to
certain exceptions. The indemnification rights conferred by each of us are not
exclusive of any other right to which persons seeking indemnification may be
entitled under any statute, our respective certificates of incorporation or
by-laws, any agreement, vote of stockholders or disinterested directors or
otherwise. In addition, each of us is authorized to, and does, purchase and
maintain insurance on behalf of its directors and officers.

                                       92
<PAGE>
    Additionally, each of us may pay expenses incurred by our directors or
officers in defending a civil or criminal action, suit or proceeding because
that person is a director or officer, in advance of the final disposition of
that action, suit or proceeding. However, such payment will be made only if we
receive an undertaking by or on behalf of that director or officer to repay all
amounts advanced if it is ultimately determined that he or she is not entitled
to be indemnified by us, as authorized by our respective certificates of
incorporation and by-laws.

    Hilton's certificate of incorporation extends the indemnification,
advancement of expenses and authorization to maintain insurance provisions
described above to employees, agents and fiduciaries of Hilton and, if serving
at Hilton's request, to employees, agents and fiduciaries of other corporations,
joint ventures, partnerships, trusts or other enterprises.

STOCKHOLDER RIGHTS PLAN


    Both Hilton and Promus have stockholder rights plans. In general, the Hilton
rights become exercisable only if a person or group acquires beneficial
ownership of 20% or more of the outstanding shares of Hilton common stock. Under
Promus' rights plan, the beneficial ownership threshold is 15% instead of 20%.
Barron Hilton and the Conrad N. Hilton Fund are excluded in determining whether
a person or group has crossed the 20% threshold in Hilton's rights plan. Promus
has taken all action necessary to render the Promus rights inapplicable to the
acquisition. More information about the Hilton and Promus rights plans are
included in their filings with the SEC. For information on how you can obtain
copies of these filings, please see the section entitled "Where You Can Find
More Information" on page 94.


               AMENDMENT TO HILTON'S CERTIFICATE OF INCORPORATION

    Hilton is asking its stockholders to approve an amendment to Hilton's
certificate of incorporation to increase the authorized number of shares of
Hilton common stock from 400 million shares to 500 million shares. A form of the
amendment is attached as Appendix F to this joint proxy statement/ prospectus.
This amendment is designed to allow for future stock issuances by Hilton for
purposes such as raising funds to repay debt, acquisition of assets or employee
incentives. If approved, the amendment to the certificate of incorporation will
take effect only if the acquisition is completed.

                         AMENDMENT TO HILTON'S BY-LAWS

    Hilton is asking its stockholders to approve an amendment to Hilton's
by-laws to change the authorized number of directors from the fixed number of 12
to a range of 10 to 20, with the exact number of directors to be set from time
to time by the board of directors. A form of the amendment is attached as
Appendix G to this joint proxy statement/prospectus. This amendment is designed
to provide Hilton greater flexibility in the composition of its board. If
approved, the amendment to the bylaws will take effect regardless of the outcome
of the votes on the acquisition and the amendment to Hilton's certificate of
incorporation.

                             STOCKHOLDER PROPOSALS

    Hilton's next annual meeting of stockholders is expected to be held on
May 11, 2000. If any Hilton stockholder intends to present a proposal at the
2000 Hilton annual meeting and wishes to have the proposal considered for
inclusion in the proxy materials for the meeting, the stockholder must submit
the proposal to the Secretary of Hilton in writing so that the proposal will be
received at Hilton's executive offices by December 2, 1999. The proposal must
meet the other requirements of the rules of the SEC relating to stockholder
proposals. Stockholder nominations or proposals must be duly submitted to the
Secretary of Hilton by March 13, 2000 in order to be eligible to be considered
at the 2000 annual meeting of Hilton stockholders.

                                       93
<PAGE>
    PROMUS WILL HAVE AN ANNUAL MEETING IN 2000 ONLY IF THE ACQUISITION IS NOT
COMPLETED. If you are a Promus stockholder and you wish to submit a proposal to
be considered for inclusion in Promus' proxy materials for its next annual
meeting, you must submit the proposal to the Secretary of Promus in writing so
that the proposal will be received at Promus' executive offices by November 26,
1999. Promus' by-laws provide that to be timely, a stockholder's notice of
nomination of a director or other proposed business must be received not fewer
than 60 nor more than 90 calendar days before the annual meeting. If the public
announcement of the meeting is not made at least 70 days before the date of the
meeting, the stockholder must make the request not later than 10 calendar days
after the announcement of the meeting.

    SECTION 1.02.  CERTAIN ACTIVITIES OF SUBSIDIARIES.  The parties hereto
acknowledge that certain Subsidiaries of the Company and of Parent (including,
for example, partnerships formed for the purpose of owning and/or operating
single hotel properties) have engaged, and may after the date hereof engage, in
the ordinary course of their or the Company's or Parent's businesses, in the
following activities: (a) the declaration, setting aside and payment of
dividends or other distributions and (b) the repurchase, redemption or other
acquisition of, or amendment to the existing terms of, capital stock or other
ownership interests of such Subsidiaries. Notwithstanding anything else in this
Agreement, the parties agree that any such activity referred to in clause (a) or
(b) by any such Subsidiary will not constitute the breach of any representation
and warranty of the Company or Parent, as the case may be, made pursuant to this
Agreement or the violation of any covenant binding on the Company or Parent, as
the case may be, pursuant to this Agreement, so long as such activity is (i) in
the ordinary course of business consistent with past practice, (ii) on arm's
length terms and (iii) permitted or required pursuant to any agreement.

                                   THE MERGER

    SECTION 2.01.  THE MERGER.  (a)  Subject to Section 2.01(e) and
Section 2.01(f), at the Effective Time, the Company shall be merged (the
"MERGER") with and into Merger Subsidiary in accordance with Delaware Law,
whereupon the separate existence of the Company shall cease, and Merger
Subsidiary shall be the surviving corporation (the "SURVIVING CORPORATION").

    (b)  As soon as practicable after satisfaction or, to the extent permitted
hereunder, waiver of all conditions to the Merger, the Company and Merger
Subsidiary will file a certificate of merger with the Delaware Secretary of
State and make all other filings or recordings required by Delaware Law in
connection with the Merger. The Merger shall become effective at such time (the
"EFFECTIVE TIME") as the certificate of merger is duly filed with the Delaware
Secretary of State or at such later time as is specified in the certificate of
merger.

    (c)  From and after the Effective Time, the Surviving Corporation shall
possess all the rights, powers, privileges and franchises and be subject to all
of the obligations, liabilities, restrictions and disabilities of the Company
and Merger Subsidiary, all as provided under Delaware Law.

    (d)  The closing of the Merger shall take place (i) at the offices of Davis
Polk & Wardwell, 450 Lexington Avenue, New York, NY, as soon as practicable, but
in any event within three business days after the day on which the last to be
fulfilled or waived of the conditions set forth in Article 9 (other than those
conditions that by their nature are to be fulfilled at the closing, but subject
to the fulfillment or waiver of such conditions) shall be fulfilled or waived in
accordance with this Agreement or (ii) at such other place and time or on such
other date as the Company and Parent may agree in writing.


    (e)  If (A) on the day upon which the Effective Time occurs (or if no
trading of Parent Stock on the NYSE takes place prior to the Effective Time on
such day, the last date prior to the date upon which the Effective Time occurs
upon which there was trading of Parent Stock on the NYSE), the fair market
value, based on the volume weighted average per share sales price of the Parent
Stock on that day on the NYSE, of all shares of Parent Stock to be delivered in
connection with the Merger (the "TOTAL STOCK VALUE") is less than 40% of the sum
of (i) the sum of the Maximum Cash Shares and Dissenting Shares, multiplied by
the Cash Consideration, (ii) the amount of cash paid by Parent to acquire Shares
within the two year period prior to the date of the Merger and (iii) the Total
Stock Value (such sum being referred to as the "TOTAL CONSIDERATION") or
(B) the conditions in Sections 9.02(b) and 9.03(b) cannot be satisfied (assuming
that the legally required minimum percentage of stock consideration under the
continuity of interest test applicable pursuant to Treasury Regulations is 40%),
then the Merger contemplated by Section 2.01(a) shall be restructured such that
Merger Subsidiary shall be merged with and into the Company, and the Company
shall be the surviving corporation. In such event: all references to the term
"Merger" shall be deemed references to the merger contemplated by this
Section 2.01(e); all references to the term "Surviving Corporation" shall be
deemed references to the Company; all references to the term "Effective Time"
shall be deemed references to the time at which the certificate of merger is
duly filed with the Delaware Secretary of State or at such later time as is
specified in the certificate of merger with respect to the Merger as
restructured in the manner contemplated by this Section 2.01(e); and the
conditions set forth in Sections 9.02(b) and 9.03(b) and the covenant set forth
in Section 8.07 shall thereafter cease to apply. The parties shall cooperate and
take all steps necessary to implement such alternative structure.
Notwithstanding Section 3.01, in the event the alternative structure
contemplated by this Section 2.01(e) is implemented, the certificate of
incorporation of the Company in effect at the Effective Time shall be the
certificate of incorporation of the Surviving Corporation until amended in
accordance with applicable law.


                                      A-5
<PAGE>
    (f)  The parties agree that after the date hereof, if Parent and the Company
are satisfied in their sole discretion that consummation of the Alternative
Double Merger Structure (as defined below) will not result in any material
adverse consequences pursuant to the Parent Notes, the parties shall use their
best efforts to implement the Alternative Double Merger Structure on the terms
and conditions contained in this Merger Agreement (preserving the economic and
financial terms of this Agreement) with such modifications to such terms and
conditions as are required to implement such structure. The "ALTERNATIVE DOUBLE
MERGER STRUCTURE" means a structure whereby the following shall occur: (i)
Parent and the Company will form a corporation under Delaware Law ("NEW HILTON")
owned and controlled equally by Parent and the Company; (ii) promptly following
the incorporation of New Hilton, Parent and the Company will cause New Hilton to
form two wholly-owned subsidiaries under Delaware Law ("PARENT MERGER
SUBSIDIARY" and "COMPANY MERGER SUBSIDIARY"); (iii) Parent and the Company will
cause New Hilton, Parent Merger Subsidiary and Company Merger Subsidiary to
become parties to this Agreement and to execute and deliver all documents
required by Delaware Law to authorize and adopt this Agreement and (iv) at the
Effective Time, (x) Company Merger Subsidiary shall be merged with and into the
Company in accordance with Delaware Law, whereupon the separate existence of
Company Merger Subsidiary shall cease, and the Company shall be the surviving
corporation and (y) Parent Merger Subsidiary shall be merged with and into
Parent in accordance with Delaware Law, whereupon the separate existence of
Parent Merger Subsidiary shall cease, and Parent shall be the surviving
corporation.

    SECTION 2.02.  CONVERSION OF SHARES.  At the Effective Time:

    (a)  Each Share held by the Company as treasury stock, held by any
Subsidiary of the Company, or owned by Parent or any of its Subsidiaries,
immediately prior to the Effective Time shall be canceled, and no payment shall
be made with respect thereto.

    (b)  Each share of common stock of Merger Subsidiary outstanding immediately
prior to the Effective Time shall be converted into and become one share of
common stock of the Surviving Corporation with the same rights, powers and
privileges as the shares so converted and shall constitute the only outstanding
shares of capital stock of the Surviving Corporation.

    (c)  Except as otherwise provided in Section 2.02(a) or Section 2.06 and
subject to Sections 2.03 and 2.04, each Share outstanding immediately prior to
the Effective Time, together with the associated Right, issued and outstanding
immediately prior to the Effective Time shall be converted into the right to
receive either (i) $38.50 in cash, without interest (the "CASH CONSIDERATION"),
or (ii) the number of shares of validly issued, fully paid and non-assessable
Parent Stock equal to the Exchange Ratio (the "STOCK CONSIDERATION").

    The "EXCHANGE RATIO" shall be a number (rounded to the nearest
ten-thousandth) determined by dividing $38.50 by the Market Price per share of
Parent Stock; PROVIDED, HOWEVER, that in no event shall the Exchange Ratio be
(x) greater than 3.2158 or (y) less than 2.9096. The "MARKET PRICE" per share of
Parent Stock shall be the average of the volume weighted average per share sales
price of Parent Stock on the New York Stock Exchange, Inc. (the "NYSE") for
twenty trading days selected by lot out of the thirty trading days ending on and
including the fifth trading day prior to the Effective Time. The consideration
provided for in this Section 2.02(c) is referred to herein as the "MERGER
CONSIDERATION".


    SECTION 2.03.  ELECTION OF CASH OR PARENT STOCK.


    (a)  Subject to Section 2.04, each holder of Shares (other than holders of
such shares that are to be canceled pursuant to Section 2.02(a)) shall be
entitled to elect to specify (i) the number of Shares which such holder desires
to have converted into the right to receive the Cash Consideration in the Merger
(a "CASH ELECTION") and (ii) the number of Shares which such holder desires to
have converted into the right to receive the Stock Consideration in the Merger
(a "STOCK ELECTION"); PROVIDED, HOWEVER, that no holder of Dissenting Shares (as
defined in Section 2.06) shall be entitled to make an Election.

                                      A-6
<PAGE>
A holder may also indicate that such record holder has no preference as to the
receipt of Cash Consideration, Stock Consideration or a combination thereof with
respect to such holder's Shares (a "NON-ELECTION"). Any Cash Election, Stock
Election or Non-Election shall be referred to herein as an "ELECTION". All such
Elections shall be made on a form furnished by Parent for that purpose (a "FORM
OF ELECTION") and reasonably satisfactory to the Company. Holders of record of
Shares who hold such Shares as nominees, trustees or in other representative
capacities may submit multiple Forms of Election, PROVIDED that such nominee,
trustee or representative certifies that each such Form of Election covers all
Shares held for a particular beneficial owner.

    (b)  Elections shall be made by holders of Shares by delivering the Form of
Election to the Exchange Agent. To be effective, a Form of Election must be
properly completed, signed and submitted to the Exchange Agent by no later than
5:00 p.m. (New York City time) on the business day preceding the date of the
Company Stockholder Meeting (the "ELECTION DATE"), and accompanied by (i)
(x) the Certificates representing the Shares as to which the election is being
made or (y) an appropriate guarantee of delivery of such Certificates as set
forth in such Form of Election from a firm which is a member of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc. or a commercial bank or trust company having an office or
correspondent in the United States, PROVIDED such Certificates are in fact
delivered to the Exchange Agent within three NYSE trading days after the date of
execution of such guarantee of delivery (a "GUARANTEE OF DELIVERY") and (ii) a
properly completed and signed letter of transmittal. Failure to deliver
Certificates covered by any Guarantee of Delivery within three NYSE trading days
after the date of execution of such Guarantee of Delivery shall be deemed to
invalidate any otherwise properly made Cash Election or Stock Election.

    (c)  The Exchange Agent will have the discretion to determine whether Forms
of Election have been properly completed, signed and submitted or revoked and to
disregard immaterial defects in Forms of Election. The good faith decision of
the Exchange Agent in such matters shall be conclusive and binding; PROVIDED
that the Exchange Agent may, in its discretion, seek guidance from Parent and
the Company in connection therewith. Neither Parent nor the Company nor the
Exchange Agent will be under any obligation to notify any person of any defect
in a Form of Election submitted to the Exchange Agent. A Form of Election with
respect to Dissenting Shares shall not be valid. The Exchange Agent shall also
make all computations contemplated by Section 2.04 and all such computations
shall be conclusive and binding on the holders of Shares in the absence of
manifest error. Any Form of Election may be changed or revoked prior to the
Election Date. In the event a Form of Election is revoked prior to the Election
Date, Parent shall, or shall cause the Exchange Agent to, cause the Certificates
representing the Shares covered by such Form of Election to be promptly returned
without charge to the Person submitting the Form of Election upon written
request to that effect from such Person.

    (d)  For the purposes hereof, a holder of Shares who does not submit a Form
of Election which is received by the Exchange Agent prior to the Election Date
(including a holder who submits and then revokes his or her Form of Election and
does not resubmit a Form of Election which is timely received by the Exchange
Agent), or who submits a Form of Election without the corresponding Certificates
or a Guarantee of Delivery, shall be deemed to have made a Non-Election. Holders
of Dissenting Shares shall not be entitled to make an Election and shall not be
deemed to have made a Non-Election; the rights of such holders of Dissenting
Shares shall be determined in accordance with Section 262 of Delaware Law and as
provided in Section 2.06 hereof. If any Form of Election is defective in any
manner such that the Exchange Agent cannot reasonably determine the election
preference of the stockholder submitting such Form of Election, the purported
Cash Election or Stock Election set forth therein shall be deemed to be of no
force and effect and the stockholder making such purported Cash Election or
Stock Election shall, for purposes hereof, be deemed to have made a
Non-Election.

                                      A-7
<PAGE>
    (e) A Form of Election and a letter of transmittal shall be included with or
mailed contemporaneously with each copy of the Joint Proxy Statement mailed to
the Company's stockholders in connection with the Company Stockholder Meeting.
Each of Parent and the Company shall use reasonable best efforts to mail or
otherwise make available the Form of Election and a letter of transmittal to all
persons who become record holders of Shares during the period between the record
date for the Company Stockholder Meeting and the Election Date.

    SECTION 2.04.  PRORATION.  The determination of whether Shares (other than
Shares that are to be canceled pursuant to Section 2.02(a)), and the associated
Rights, shall be converted in the Merger into the Stock Consideration or the
Cash Consideration shall be made as set forth in this Section 2.04.

    (a) As is more fully set forth below, the aggregate number of Shares to be
converted in the Merger into the right to receive the Cash Consideration shall
equal the Maximum Cash Shares. The "MAXIMUM CASH SHARES" means 55% of the
Aggregate Shares, less any Dissenting Shares. The "AGGREGATE SHARES" means all
Shares issued and outstanding immediately prior to the Effective Time other than
those Shares which are to be canceled in accordance with Section 2.02(a).

    (b) If Cash Elections are received for a number of Shares which is more than
the Maximum Cash Shares:

        (i)  each Share subject to a Non-Election (a "NON-ELECTING SHARE") and
    each Share for which a Stock Election has been received (in each case,
    together with the associated Right) shall be converted in the Merger into
    the Stock Consideration; and

        (ii)  the Shares for which Cash Elections have been received (and the
    associated Rights) shall be converted in the Merger into the Cash
    Consideration and the Stock Consideration in the following manner: For each
    Cash Election, the number of Shares covered by such Cash Election that shall
    receive the Cash Consideration shall be the total number of Shares covered
    by such Cash Election multiplied by the Cash Proration Factor. The "CASH
    PRORATION FACTOR" means a fraction the numerator of which shall be a number
    equal to the Maximum Cash Shares and the denominator of which shall be the
    aggregate number of Shares covered by all Cash Elections made by all holders
    of Shares. All Shares covered by a Cash Election, other than that number
    converted into the right to receive the Cash Consideration in accordance
    with this Section 2.04(b)(ii), shall be converted into the right to receive
    the Stock Consideration.

    (c) If Stock Elections are received for a number of Shares which is more
than 45% of the Aggregate Shares,

        (i)  each Non-Electing Share and each Share for which a Cash Election
    has been received (in each case, together with the associated Right) shall
    be converted in the Merger into the Cash Consideration; and

        (ii)  the Shares for which Stock Elections have been received shall be
    converted in the Merger into the Stock Consideration and the Cash
    Consideration in the following manner: For each Stock Election, the number
    of Shares covered by such Stock Election that shall receive the Stock
    Consideration shall be the total number of Shares covered by such Stock
    Election multiplied by the Stock Proration Factor. The "STOCK PRORATION
    FACTOR" means a fraction the numerator of which shall be a number equal to
    45% of the Aggregate Shares and the denominator of which shall be the
    aggregate number of Shares covered by all Stock Elections made by all
    holders of Shares. All Shares covered by a Stock Election, other than that
    number converted into the right to receive the Stock Consideration in
    accordance with this Section 2.04(c)(ii), shall be converted into the right
    to receive the Cash Consideration.

    (d) If Cash Elections are received for a number of Shares which is equal to
the Maximum Cash Shares, each Share covered by a Cash Election shall be
converted in the Merger into the Cash

                                      A-8
<PAGE>
Consideration, and each Share covered by a Stock Election and each Non-Electing
Share shall be converted in the Merger into the Stock Consideration.

    (e) If Non-Electing Shares are not converted under either Section 2.04(b),
Section 2.04(c) or 2.04(d), the Exchange Agent shall determine by lot (or by
such other method as is deemed reasonable by Parent and the Company) which of
such Non-Electing Shares shall be converted in the Merger into the Cash
Consideration; PROVIDED, HOWEVER, that such selection by lot (or by such other
method) will cease when the sum of the shares converted in such manner, plus the
number of Shares covered by all Cash Elections made by the holders of Shares is
equal to the Maximum Cash Shares. Each Non-Electing Share not so converted into
the Cash Consideration shall be converted in the Merger into the Stock
Consideration.

    SECTION 2.05.  SURRENDER AND PAYMENT.  (a) Prior to the record date for the
Company Stockholder Meeting, Parent shall appoint an agent (the "EXCHANGE
AGENT") reasonably acceptable to the Company for the purpose of exchanging
certificates representing Shares (the "CERTIFICATES") for the Merger
Consideration and for purposes of receiving Election Forms and determining, in
accordance with Sections 2.02, 2.03 and 2.04 the form of the Merger
Consideration to be received by each holder of Shares. At the Effective Time,
Parent will deposit with the Exchange Agent the Merger Consideration to be paid
in respect of the Shares. For the purpose of determining the Merger
Consideration to be made available, Parent shall assume that no holders of
Shares will perfect rights to appraisal of their Shares.

    (b) Each holder of Shares that have been converted into the right to receive
the Merger Consideration will be entitled to receive, upon surrender to the
Exchange Agent of a Certificate, together with a properly completed letter of
transmittal, the Merger Consideration payable for each Share represented by such
Certificate. Until so surrendered, each such Certificate shall represent after
the Effective Time for all purposes only the right to receive such Merger
Consideration.

    (c) If any portion of the Merger Consideration is to be paid to a Person
other than the Person in whose name the surrendered Certificate is registered,
it shall be a condition to such payment that the Certificate so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such payment shall pay to the Exchange Agent any transfer
or other taxes required as a result of such payment to a Person other than the
registered holder of such Certificate or establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable.

    (d) After the Effective Time, there shall be no further registration of
transfers of Shares. If, after the Effective Time, Certificates are presented to
the Surviving Corporation, they shall be canceled and exchanged for the Merger
Consideration provided for, and in accordance with the procedures set forth, in
this Article.

    (e) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 2.05(a) (and any interest or other income earned
thereon) that remains unclaimed by the holders of Shares one year after the
Effective Time shall be returned to Parent, upon demand, and any such holder who
has not exchanged Shares for the Merger Consideration in accordance with this
Section prior to that time shall thereafter look only to Parent for payment of
the Merger Consideration in respect of such Shares without any interest thereon.
Notwithstanding the foregoing, Parent shall not be liable to any holder of
Shares for any amount paid to a public official pursuant to applicable abandoned
property, escheat or similar laws. Any amounts remaining unclaimed by holders of
Shares three years after the Effective Time (or such earlier date immediately
prior to such time when the amounts would otherwise escheat to or become
property of any governmental authority) shall become, to the extent permitted by
applicable law, the property of Parent free and clear of any claims or interest
of any Person previously entitled thereto.

                                      A-9
<PAGE>
    (f) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 2.05(a) to pay for Shares for which appraisal rights
have been perfected shall be returned to Parent, upon demand.

    (g) No dividends or other distributions with respect to any Parent Stock
constituting part of the Merger Consideration shall be paid to the holder of any
unsurrendered Certificates until such Certificates are surrendered as provided
in this Section. Subject to the effect of applicable laws, following such
surrender, there shall be paid, without interest, to the record holder of the
Parent Stock issued in exchange therefor (i) at the time of such surrender, all
dividends and other distributions payable in respect of such Parent Stock with a
record date after the Effective Time and a payment date on or prior to the date
of such surrender and not previously paid and (ii) at the appropriate payment
date, the dividends or other distributions payable with respect to such Parent
Stock with a record date after the Effective Time but with a payment date
subsequent to such surrender.

    SECTION 2.06.  DISSENTING SHARES.  Shares outstanding immediately prior to
the Effective Time and held by a holder who has not voted in favor of the Merger
or consented thereto in writing and who has demanded appraisal for such Shares
in accordance with Delaware Law ("DISSENTING SHARES") shall not be converted
into a right to receive the Merger Consideration, unless such holder fails to
perfect, withdraws or otherwise loses its right to appraisal. If, after the
Effective Time, such holder fails to perfect, withdraws or loses its right to
appraisal, such Shares shall be treated as if they had been converted as of the
Effective Time into a right to receive the Merger Consideration and shall be
deemed to have been subject to a Non-Election. The Company shall give Parent
prompt notice of any demands received by the Company for appraisal of Shares.
Except as required by applicable law or with the prior written consent of
Parent, the Company shall not make any payment with respect to, or settle or
offer to settle, any such demands.

    SECTION 2.07.  STOCK OPTIONS.

    (a) Each stock option to purchase Shares outstanding under any employee or
director stock option or compensation plan or arrangement of the Company (a
"COMPANY STOCK OPTION") shall be canceled, and the Company shall pay the holder
of such Company Stock Option at or promptly after the Effective Time an amount
in cash determined by multiplying the excess, if any, of the Cash Consideration
over the applicable exercise price of such Company Stock Option by the number of
Shares such holder could have purchased (assuming full vesting of such option)
had such holder exercised such option in full immediately prior to the Effective
Time.

    (b) Parent, the Company and their Boards of Directors shall take all steps
necessary to cause the payments referred to in this Section 2.07 to be exempt
transactions pursuant to Rule 16b-3 promulgated by the Securities and Exchange
Commission.

    SECTION 2.08.  DEFERRED SHARES; GE WARRANTS; GE OPTIONS.  (a)  Each
participant in the Promus Hotel Corporation 1996 Non-Management Directors Stock
Incentive Plan (as amended, the "DIRECTORS PLAN") or the Independent Director
Equity Participation Program under The 1997 Equity Participation Plan of Promus
Hotel Corporation (the "DIRECTORS PROGRAM"), as applicable, will be provided
with a Form of Election and given the opportunity to make an Election with
respect to all Shares credited to such participant's account under the Directors
Plan or the Directors Program, whether or not previously vested ("CREDITED
SHARES"), at the same time and in the same manner as holders of Shares are given
the opportunity to make Elections. Upon consummation of the Merger, each such
participant shall have rights with respect to such Credited Shares that are
identical to those of a holder of Shares who had made the same Election as that
made by such participant.

    (b) At the Effective Time, Parent shall assume all obligations under the GE
Warrants, and the holder of the GE Warrants thereafter shall have the right to
acquire, on the same pricing and payment terms and conditions as are currently
applicable under the GE Warrants, the same number of shares of

                                      A-10
<PAGE>
Parent Stock as the holder of the GE Warrants would have been entitled to
receive pursuant to the Merger had such holder exercised the GE Warrants in full
immediately prior to the Effective Time (rounded up to the nearest whole number)
and made a Stock Election in connection with the Merger that was not subject to
proration, at the price per share (rounded down to the nearest whole cent) equal
to (y) the aggregate exercise price for the Shares purchasable pursuant to the
GE Warrants immediately prior to the Effective Time divided by (z) the number of
full shares of Parent Stock deemed purchasable pursuant to the GE Warrants in
accordance with the foregoing.

    (c) At the Effective Time, Parent shall assume all obligations under the GE
Options, and each holder of the GE Options thereafter shall have the right to
acquire, on the same pricing and payment terms and conditions as are currently
applicable under the GE Options, the same number of shares of Parent Stock as
such holder of the GE Options would have been entitled to receive pursuant to
the Merger had such holder exercised the GE Options in full immediately prior to
the Effective Time (rounded up to the nearest whole number) and made a Stock
Election in connection with the Merger that was not subject to proration, at the
price per share (rounded down to the nearest whole cent) equal to (y) the
aggregate exercise price for the Shares purchasable pursuant to the GE Options
immediately prior to the Effective Time divided by (z) the number of full shares
of Parent Stock deemed purchasable pursuant to the GE Options in accordance with
the foregoing.

    SECTION 2.09.  FRACTIONAL SHARES.  (a) No fractional shares of Parent Stock
shall be issued in the Merger, but in lieu thereof each holder of Shares
otherwise entitled to a fractional share of Parent Stock will be entitled to
receive, from the Exchange Agent in accordance with the provisions of this
Section 2.09, a cash payment in lieu of such fractional shares of Parent Stock
representing such holder's proportionate interest, if any, in the proceeds from
the sale by the Exchange Agent in one or more transactions of the number of
shares of Parent Stock delivered to the Exchange Agent by Parent pursuant to
Section 2.05(a) over the aggregate number of whole shares of Parent Stock to be
distributed to the holders of the certificates representing Shares pursuant to
Section 2.05(b) (such excess being herein called the "EXCESS SHARES"). As soon
as practicable after the Effective Time, the Exchange Agent, as agent for the
holders of the certificates representing Shares, shall sell the Excess Shares at
then prevailing prices on the NYSE in the manner provided in the following
paragraph.

    (b) The sale of the Excess Shares by the Exchange Agent, as agent for the
holders that would otherwise receive fractional shares, shall be executed on the
NYSE through one or more member firms of the NYSE and shall be executed in round
lots to the extent practicable. The compensation payable to the Exchange Agent
and the expenses incurred by the Exchange Agent, in each case, in connection
with such sale or sales of the Excess Shares, and all related commissions,
transfer taxes and other out-of-pocket transaction costs, will be paid by the
Surviving Corporation out of its own funds and will not be paid directly or
indirectly by Parent. Until the proceeds of such sale or sales have been
distributed to the holders of Shares, the Exchange Agent shall hold such
proceeds in trust for the holders of Shares (the "COMMON SHARES TRUST"). The
Exchange Agent shall determine the portion of the Common Shares Trust to which
each holder of Shares shall be entitled, if any, by multiplying the amount of
the aggregate proceeds comprising the Common Shares Trust by a fraction, the
numerator of which is the amount of the fractional share interest to which such
holder of Shares would otherwise be entitled and the denominator of which is the
aggregate amount of fractional share interests to which all holders of Shares
would otherwise be entitled.

    (c) As soon as practicable after the determination of the amount of cash, if
any, to be paid to holders of Shares in lieu of any fractional shares of Parent
Stock, the Exchange Agent shall make available such amounts to such holders of
Shares without interest.

    SECTION 2.10.  WITHHOLDING RIGHTS.  Each of the Surviving Corporation and
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable to any Person pursuant to this Article such amounts as it is required to
deduct and withhold with respect to the making of such

                                      A-11
<PAGE>
payment under any provision of federal, state, local or foreign tax law. If the
Surviving Corporation or Parent, as the case may be, so withholds amounts, such
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Shares in respect of which the Surviving Corporation or
Parent, as the case may be, made such deduction and withholding.

    SECTION 2.11.  LOST CERTIFICATES.  If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue, in exchange for such lost, stolen or destroyed
Certificate, the Merger Consideration to be paid in respect of the Shares
represented by such Certificate, as contemplated by this Article.

                                   ARTICLE 3
                           THE SURVIVING CORPORATION

    SECTION 3.01.  CERTIFICATE OF INCORPORATION.  The certificate of
incorporation of Merger Subsidiary in effect at the Effective Time shall be the
certificate of incorporation of the Surviving Corporation until amended in
accordance with applicable law, PROVIDED that, at the Effective Time, such
certificate of incorporation shall be amended to provide that the name of the
Surviving Corporation shall be Promus Hotel Corporation.

    SECTION 3.02.  BYLAWS.  The bylaws of Merger Subsidiary in effect at the
Effective Time shall be the bylaws of the Surviving Corporation until amended in
accordance with applicable law.

    SECTION 3.03.  DIRECTORS AND OFFICERS.  From and after the Effective Time,
until successors are duly elected or appointed and qualified in accordance with
applicable law, (i) the directors of Merger Subsidiary at the Effective Time
shall be the directors of the Surviving Corporation and (ii) the officers of the
Company at the Effective Time shall be the officers of the Surviving
Corporation.

                                   ARTICLE 4
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    Except as set forth in the corresponding sections or subsections of the
disclosure schedule delivered to Parent by the Company on or prior to the date
hereof (the "COMPANY DISCLOSURE SCHEDULE") or in the Company SEC Documents, the
Company represents and warrants to Parent that:

    SECTION 4.01.  CORPORATE EXISTENCE AND POWER.  The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware and has all corporate powers and all governmental licenses,
authorizations, permits, consents and approvals required to carry on its
business as now conducted, except for those licenses, authorizations, permits,
consents and approvals the absence of which would not reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect. The
Company is duly qualified to do business as a foreign corporation and is in good
standing in each jurisdiction where such qualification is necessary, except for
those jurisdictions where failure to be so qualified would not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect. The Company has heretofore made available to Parent true and complete
copies of the certificate of incorporation and bylaws of the Company as
currently in effect.

    SECTION 4.02.  CORPORATE AUTHORIZATION.  The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company
of the transactions contemplated hereby are within the Company's corporate
powers and, except for the affirmative vote of the holders of a majority of the
outstanding Shares in connection with the consummation of the Merger, have been

                                      A-12
<PAGE>
duly authorized by all necessary corporate action on the part of the Company.
The affirmative vote of the holders of a majority of the outstanding Shares is
the only vote of the holders of any of the Company's capital stock necessary in
connection with the consummation of the Merger. This Agreement constitutes a
valid and binding agreement of the Company.

    SECTION 4.03.  GOVERNMENTAL AUTHORIZATION.  The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company
of the transactions contemplated hereby require no action by or in respect of,
or filing with, any governmental body, agency, official or authority, domestic
or foreign, other than (i) the filing of a certificate of merger with respect to
the Merger with the Delaware Secretary of State and appropriate documents with
the relevant authorities of other states in which the Company is qualified to do
business, (ii) compliance with any applicable requirements of the HSR Act, (iii)
compliance with any applicable requirements of the 1933 Act, the 1934 Act and
any other applicable securities or takeover laws, whether state or foreign, (iv)
such consents, approvals, orders, authorizations, permits, filings or
registrations of or with any governmental entity related to, or arising out of,
compliance with statutes, rules or regulations regulating the consumption, sale
or serving of alcoholic beverages and (v) any actions or filings the absence of
which would not be reasonably expected to have, individually or in the
aggregate, a Company Material Adverse Effect or materially impair the ability of
the Company to consummate the transactions contemplated by this Agreement or
delay the consummation of the transactions contemplated by this Agreement beyond
the Outside Termination Date.

    SECTION 4.04.  NON-CONTRAVENTION.  The execution, delivery and performance
by the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not (i) contravene, conflict
with, or result in any violation or breach of any provision of the certificate
of incorporation or bylaws of the Company, (ii) assuming compliance with the
matters referred to in Section 4.03, contravene, conflict with, or result in a
violation or breach of any provision of any applicable law, regulation,
judgment, injunction, order or decree, (iii) except as to Material Company
Agreements (which are addressed in Section 4.24), require any consent or other
action by any Person under, constitute a default under, or cause or permit the
termination, cancellation, acceleration or other change of any right or
obligation or the loss of any benefit to which the Company or any of its
Subsidiaries is entitled under any provision of any agreement or other
instrument binding upon the Company or any of its Subsidiaries or any license,
franchise, permit, certificate, approval or other similar authorization
affecting, or relating in any way to, the assets or business of the Company and
its Subsidiaries or (iv) result in the creation or imposition of any Lien on any
asset of the Company or any of its Subsidiaries, except for such contraventions,
conflicts and violations referred to in clause (ii) and for such failures to
obtain any such consent or other action, defaults, terminations, cancellations,
accelerations, changes, losses or Liens referred to in clauses (iii) and
(iv) that would not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.

    SECTION 4.05.  CAPITALIZATION.  (a) The authorized capital stock of the
Company consists of 500,000,000 Shares and 10,000,000 shares of preferred stock,

Revenue Service determination letters, most recent filings on Form 5500,
actuarial valuations, financial statements, and any correspondence with a
government agency relating thereto) and all amendments thereto and written

    (c) Each Company Employee Plan which is intended to be qualified under
Section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service, and the Company knows of no fact or circumstance
giving rise to a material likelihood that the plan would not be treated as so
qualified by the Internal Revenue Service. Each Company Employee Plan has been
maintained in material compliance with its terms and with the requirements
prescribed by any and all

                                      A-18
<PAGE>
statutes, orders, rules and regulations, including but not limited to ERISA and

    has been assessed, and no investigation, action, claim, suit, proceeding or
    review (or any basis therefor) is pending or, to the knowledge of the
    Company, is threatened by any governmental entity or other Person with
    respect to any matters relating to the Company or any Subsidiary and
    relating to or arising out of any Environmental Law;

        (ii) the Company and its Subsidiaries are in compliance with all
    applicable Environmental Laws and all Environmental Permits; and

       (iii) there are no liabilities or obligations of the Company or any of
    its Subsidiaries, whether accrued, contingent, absolute, determined,
    determinable or otherwise arising under or relating to any Environmental
    Law.

    SECTION 4.18.  ANTITAKEOVER STATUTES; RIGHTS AGREEMENT; DIRECTOR VOTES.  (a)
The Company has taken all action necessary to exempt the Merger, this Agreement

<PAGE>
software programs or applications and tangible or intangible proprietary
information or material that are necessary to conduct the business of the
Company as currently conducted, subject to such exceptions that, individually
and in the aggregate, would not be reasonably likely to have a Company Material
Adverse Effect. The Company has no knowledge of any assertion or claim
challenging the validity of any of such intellectual property that would be
reasonably likely to have a Company Material Adverse Effect.

    SECTION 4.22.  REAL PROPERTY.  (a) Neither the Company nor any of its
Subsidiaries has received a notice of default or termination under any leases
for real property providing for the occupancy, in each case, of (i) a hotel or
(ii) other facilities in excess of 50,000 square feet except where the existence
of such notices, individually or in the aggregate, is not reasonably likely to
have a Company Material Adverse Effect.

    (b) With respect to the real property that the Company and any of its
Subsidiaries own, the Company or one of its Subsidiaries has title sufficient to
conduct the business of the Company and its Subsidiaries as currently conducted,
except for such matters as would not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect.

    SECTION 4.23.  YEAR 2000 COMPLIANCE.  The Company and its Subsidiaries have
(i) completed a review and assessment of all areas within the business and
operations of the Company and its Subsidiaries that could be adversely affected

used by the Company or any of its Subsidiaries may be unable to recognize and
perform properly date-sensitive functions involving certain dates prior to, on,
and any date after December 31, 1999) and (ii) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, which plan and timeline have
been made available to Parent.

available to Parent, or otherwise identified, all material management, license
and franchise agreements (or forms thereof) to which the Company or any of its
Subsidiaries is a party (collectively, the "MATERIAL COMPANY AGREEMENTS") that
contain material radius or non-competition restrictions which would prohibit
Parent or its Subsidiaries (as determined immediately prior to the Effective
Time) from the ownership, operation or management of any of their respective
currently owned hotel properties or that require any consent or other action by
any Person for, or will be subject to default, termination or cancellation
because of, the transactions contemplated hereby, other than (x) those
agreements the loss of the net income from which, individually or in the
aggregate, would not have a Company Material Adverse Effect or (y) those
agreements the Company has the right or the ability to terminate and the loss of
net income from which, or any payment required to be made or otherwise payable
in connection therewith, individually or in the aggregate, would not have a
Company Material Adverse Effect. Neither the Company nor any of its Subsidiaries
has received as of the date hereof a notice of default or termination under any
Material Company Agreement, except where the existence of such notices,
individually or in the aggregate, is not reasonably likely to have a Company
Material Adverse Effect.

                    REPRESENTATIONS AND WARRANTIES OF PARENT

    Except as set forth in the corresponding sections or subsections of the
disclosure schedule delivered to the Company by Parent on or prior to the date
hereof (the "PARENT DISCLOSURE SCHEDULE") or in the Parent SEC Documents, Parent
represents and warrants to the Company that:

    SECTION 5.01.  CORPORATE EXISTENCE AND POWER.  Each of Parent and Merger
Subsidiary is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
corporate powers and all governmental licenses, authorizations, permits,
consents and approvals required to carry on its business as now conducted,
except for those licenses,

                                      A-20
<PAGE>
authorizations, permits, consents and approvals the absence of which would not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Parent is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where such
qualification is necessary, except for those jurisdictions where failure to be
so qualified would not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. Parent has heretofore made
available to the Company true and complete copies of the certificate of
incorporation and bylaws of Parent and Merger Subsidiary as currently in effect.
Since the date of its incorporation, Merger Subsidiary has not engaged in any
activities other than in connection with or as contemplated by this Agreement or
in connection with arranging any financing required to consummate the
transactions contemplated hereby.

    SECTION 5.02.  CORPORATE AUTHORIZATION.  The execution, delivery and
performance by Parent and Merger Subsidiary of this Agreement and the
consummation by Parent and Merger Subsidiary of the transactions contemplated
hereby are within the corporate powers of Parent and Merger Subsidiary and,
except for any required approval by the stockholders of Parent of the issuance
of shares of Parent Stock in connection with the Merger, have been duly
authorized by all necessary corporate action. The affirmative vote of the
holders of a majority of the outstanding shares of Parent Stock is the only vote
of the holders of any of Parent's capital stock necessary in connection with
consummation of the Merger. This Agreement constitutes a valid and binding
agreement of each of Parent and Merger Subsidiary.

<PAGE>
    (e) Neither Parent nor any of its Subsidiaries is or has been a member of an
affiliated group of corporations (within the meaning of Section 1504(a)) filing
a consolidated federal income tax return (or a group of corporations filing a
consolidated, combined or unitary income tax return under comparable provisions

    (g) Parent (i) is not aware of any fact or circumstance as of the date
hereof which is reasonably likely to cause the Merger to fail to qualify as a
"reorganization" within the meaning of Section 368(a) of the Code, PROVIDED that
Merger Subsidiary is the surviving corporation in the Merger and (ii) is not
aware of any fact or circumstance (including the Merger), or combination
thereof, which has caused or may cause the distribution by Parent of Park Place
Entertainment Corporation ("PPEC") on December 31, 1998 (the "DISTRIBUTION") to
fail to qualify as a tax-free transaction under Section 355(a) and (c) of the
Code.

    (h) The representations set forth in the private letter ruling issued by the
IRS to Parent dated December 10, 1998, and the representations made by Parent in
its request (and any supplements thereto) for such private letter ruling, were
true, correct and complete in all respects at the date of the Distribution and
are true, correct and complete in all respects on the date hereof.

    (i) At the time of the Distribution, neither Parent, PPEC, nor any
"Controlling Shareholder" (as defined below) of either corporation anticipated,
in light of (i) industry trends, (ii) any information known regarding the
intentions of the managements of corporations engaging in businesses similar to
those of Parent and PPEC, and (iii) the general economic climate at the time of
the distribution, that it was more likely than not that one or more persons
would acquire a 50-percent or greater interest in Parent or PPEC within 2 years
after the Distribution (or later pursuant to an agreement, understanding, or
arrangement existing at the time of the Distribution or within 6 months
thereafter) who would not have acquired such interests if the Distribution had
not occurred. For purposes of this representation, "CONTROLLING SHAREHOLDER"
means any stockholder of (i) Parent who directly or indirectly together with
related persons (as described in Sections 267(b) and 707(b) of the Code) owned
5 percent or more of any class of stock of Parent and who actively participated
in the management of Parent, or (ii) PPEC who immediately after the Distribution
directly or indirectly together with related persons (as described in Sections
267(b) and 707(b) of the Code) owned 5 percent or more of any class of stock of
PPEC and who actively participated in the management of PPEC.

    (j) The Parent Disclosure Schedule sets forth Parent's federal income tax
basis, at the time of the Distribution, in the shares of PPEC distributed to its
stockholders.

    (k) Parent has received an opinion from Gibson, Dunn & Crutcher LLP to the
effect that the Merger pursuant to this Agreement will not cause the
Distribution to fail to qualify as a tax-free transaction under Section 355(a)
and (c) of the Code. In rendering such opinion Gibson, Dunn & Crutcher LLP shall
be entitled to rely upon certain documentation including representations of
officers and shareholders of Parent.

Disclosure Schedule contains a correct and complete list identifying each
"employee benefit plan," as defined in Section 3(3) of ERISA, each written
employment, severance or similar contract, plan, arrangement or policy and each
other plan or arrangement providing for compensation, bonuses, profit-sharing,
stock option or other stock related rights or other forms of incentive or
deferred compensation, vacation benefits, insurance coverage (including any
self-insured arrangements), health or medical benefits,

severance benefits, change of control benefits and post-employment or retirement
benefits (including compensation, pension, health, medical or life insurance
benefits) which is maintained, administered or contributed to by Parent or any
ERISA Affiliate and covers any employee or former employee of Parent or any of
its Subsidiaries, or with respect to which Parent or any of its Subsidiaries or
ERISA Affiliates has any liability. Copies of such plans (and, if applicable,
related trust agreements, insurance policies and other funding documents
relating thereto, Internal Revenue Service determination letters, most recent
filings on Form 5500, actuarial valuations, financial statements, and any
correspondence with a government agency relating thereto) and all amendments

available upon request, to the Company. Such plans are referred to collectively

in Section 5.16(a) of the Parent Disclosure Schedule, neither Parent nor any
ERISA Affiliate maintains, contributes to, has any obligation to contribute to,

to, had an obligation to contribute to, or participated in, any plan that
constitutes or constituted a defined benefit or money purchase pension plan, as
defined in Section 412 of the Code or ERISA, a Multiemployer Plan, a "multiple
employer plan," as defined in ERISA, or that is or was subject to Title IV of
ERISA.

    (c) Each Parent Employee Plan which is intended to be qualified under
Section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service, and Parent knows of no fact or circumstance giving
rise to a material likelihood that the plan would not be treated as so qualified
by the Internal Revenue Service. Each Parent Employee Plan has been maintained
in material compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations, including but not limited
to ERISA and the Code, which are applicable to such Parent Employee Plan. No
material audit or investigation by any governmental authority is pending or, to
the knowledge of Parent, threatened, regarding any Parent Employee Plan.

    (d) No Parent Employee Plan provides for post-employment welfare benefits of
any kind, except as may be required by Section 4980B of the Code.

    (e) With respect to the Parent Employee Plans which are Multiemployer Plans,
(i) during the last six years neither Parent nor any ERISA Affiliate thereof has
incurred any complete or partial withdrawal, withdrawal liability, or any other
obligation or liability under Title IV of ERISA (including Section 4212(c))
(other than contributions due in the normal course); and (ii) no such Plan is in
reorganization status, is insolvent, has terminated, or suffered a mass
withdrawal.

    SECTION 5.17.   ENVIRONMENTAL MATTERS.  Except as would not reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect:

           (i) no notice, notification, demand, request for information,
       citation, summons or order has been received, no complaint has been
       filed, no penalty has been assessed, and no investigation, action, claim,
       suit, proceeding or review (or any basis therefor) is pending or, to the
       knowledge of Parent, is threatened by any governmental entity or other
       Person with respect to any matters relating to Parent or any Subsidiary
       and relating to or arising out of any Environmental Law;

           (ii) the Parent and its Subsidiaries are in compliance with all
       applicable Environmental Laws and all Environmental Permits; and

           (iii) there are no liabilities or obligations of Parent or any of its
       Subsidiaries, whether accrued, contingent, absolute, determined,
       determinable or otherwise arising under or relating to any Environmental
       Law.

    SECTION 5.18.   FINANCING.   Parent has received and furnished a copy to the
Company of a commitment letter (including the Summary of Terms and Conditions
annexed thereto, the "COMMITMENT LETTER") with Bank of America, N.A. and Bank of
America Securities LLC (collectively, "BANK OF AMERICA") dated as of
September 3, 1999. The funds which Bank of America has agreed, subject to the
terms and conditions of the Commitment Letter, to provide will be sufficient,
when taken together with funds available pursuant to (A) Parent's Existing
Senior Credit Facility (as defined in the Commitment Letter) (the "EXISTING
SENIOR CREDIT FACILITY"), as amended as contemplated by the Commitment Letter,
and (B) other funds available to Parent, to pay all cash amounts payable to

indebtedness of the Company and its Subsidiaries or of Parent and its
Subsidiaries that is required as a result of the transactions contemplated by
this Agreement, and to pay all related fees and expenses (such amount, the

also agreed to purchase assignments of commitments and loans outstanding under
the Existing Senior Credit Facility to the extent, if any, necessary to enable
Bank of America and any other lenders under the Existing Senior Credit Facility
that consent to such amendment, to adopt any amendment, waiver or other
modification necessary under the Existing Senior Credit Facility to permit the
consummation of the transactions contemplated by this Agreement and all
financings and refinancings required to consummate such transactions. Parent
knows of no facts or circumstances as of the date hereof that would result in
any of the conditions set forth in the Commitment Letter not being satisfied.

    SECTION 5.19.  ANTITAKEOVER STATUTES; RIGHTS AGREEMENT; DIRECTOR VOTES.  (a)
Parent has taken all action necessary to exempt the Merger, this Agreement and
the transactions contemplated hereby from the provisions of Section 203 of
Delaware Law, any other applicable antitakeover or similar statute or regulation
and the business combination provisions of Article IX of Parent's certificate of
incorporation.

    (b) Under the terms of the Amended and Restated Rights Agreement dated as of
September 10, 1998 between Parent and ChaseMellon Shareholder Services, L.L.C.,
as amended as of September 3, 1999 (the "PARENT RIGHTS AGREEMENT"), neither the
execution of this Agreement nor the transactions contemplated hereby will cause
a "Distribution Date" to occur or otherwise cause the rights ("PARENT RIGHTS")
issued pursuant to the Parent Rights Agreement to become exercisable, and all
such rights shall be non-exercisable at the Effective Time.

    (c) Parent has been advised that all of its directors who own shares of
Parent Stock intend to vote in favor of the Merger.

normal risks incident to the business of Parent and its Subsidiaries and their
respective properties and assets, and are in character and amount comparable to
that carried by persons engaged in similar businesses and subject to the same or
similar perils or hazards, except for any such failures to maintain insurance
policies that, individually or in the aggregate, are not reasonably likely to
have a Parent Material Adverse Effect.

    SECTION 5.21.  INTELLECTUAL PROPERTY.  Parent owns, or is licensed or
otherwise possesses legally enforceable rights to use, all trademarks, trade
names, service marks, copyrights, and any applications for such trademarks,
trade names, service marks and copyrights, know-how, computer software programs
or applications and tangible or intangible proprietary information or material
that are necessary to conduct the business of Parent as currently conducted,
subject to such exceptions that, individually and in the aggregate, would not be
reasonably likely to have a Parent Material Adverse Effect. Parent has no
knowledge of any assertion or claim challenging the validity of any of such
intellectual property that would be reasonably likely to have a Parent Material
Adverse Effect.

    SECTION 5.22.  REAL PROPERTY.  (a) Neither Parent nor any of its
Subsidiaries has received a notice of default or termination under any leases
for real property providing for the occupancy, in each case, of (i) a hotel or
(ii) other facilities in excess of 50,000 square feet except where the existence
of such notices, individually or in the aggregate, is not reasonably likely to
have a Parent Material Adverse Effect.

    (b) With respect to the real property that Parent and any of its
Subsidiaries own, Parent or its Subsidiary has title sufficient to conduct the
business of Parent and its Subsidiaries as currently conducted, except for such
matters as would not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect.

    SECTION 5.23.  YEAR 2000 COMPLIANCE.  Parent and its Subsidiaries have
(i) completed a review and assessment of all areas within the business and
operations of Parent and its Subsidiaries that could be adversely affected by
the "Year 2000 Problem" (that is, the risk that computer software and systems
used by Parent or any of its Subsidiaries may be unable to recognize and perform
properly date-sensitive functions involving certain dates prior to, on, and any
date after December 31, 1999) and (ii) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, which plan and timeline have
been made available to the Company.

    SECTION 5.24.  MANAGEMENT AND FRANCHISE AGREEMENTS.  Parent has made
available to the Company, or otherwise identified, all material management and
franchise agreements (or forms thereof) to which Parent or any of its
Subsidiaries is a party (collectively, the "MATERIAL PARENT AGREEMENTS") that
contain material radius or non-competition restrictions which would prohibit the
Company or its Subsidiaries (as determined immediately prior to the Effective
Time) from the ownership, operation or management of any of their respective
currently owned hotel properties or that require any consent or other action by
any Person for, or will be subject to default, termination or cancellation
because of, the transactions contemplated hereby, other than (x) those
agreements the loss of the net income from which, individually or in the
aggregate, would not have a Parent Material Adverse Effect or (y) those
agreements Parent has the right or the ability to terminate and the loss of net
income from which, or any payment required to be made or otherwise payable in
connection therewith, individually or in the aggregate, would not have a Parent
Material Adverse Effect. Neither Parent nor any of its Subsidiaries has received
as of the date hereof a notice of default or termination under any Material
Parent Agreement, except where the existence of such notices, individually or in
the aggregate, is not reasonably likely to have a Parent Material Adverse
Effect.

    SECTION 5.25.  OPINION OF FINANCIAL ADVISOR.  Parent has received the
written opinions of Morgan Stanley & Co. Incorporated and Donaldson, Lufkin &
Jenrette Securities Corporation, financial advisors to Parent, each to the
effect that, as of the date of this Agreement, the Merger Consideration is fair
to Parent from a financial point of view.

other aspects of the proposal including the nature and sufficiency of financing
for such proposal and the Person making the proposal, (i) would, if consummated,
result in a transaction that is more favorable to the Company's stockholders (in
their capacities as stockholders) from a financial point of view, than the

indirectly, (i) take any action to solicit or initiate the submission of any
Acquisition Proposal or (ii) engage in discussions or negotiations with, or
disclose any nonpublic information relating to the Company or any of its
Subsidiaries to, any Person who, to the knowledge of the Company, is considering
making, or has made, an Acquisition Proposal; PROVIDED that the Company may
negotiate or otherwise engage in discussions with, and furnish nonpublic
information to, any Person in response to an unsolicited Acquisition Proposal if
(w) the Company has complied with the terms of Section 6.03(b), (x) the Board of
Directors of the Company determines in good faith that, based on the terms and
conditions contained in such Acquisition Proposal, such Acquisition Proposal
could reasonably be expected to constitute a Superior Proposal, (y) prior to
providing any information or data to any Person in connection with an
Acquisition Proposal, such Person executes a confidentiality agreement with
terms substantially similar to those contained in the Confidentiality Agreement
(except as to the standstill provisions, PROVIDED that if the Company so enters
into any such confidentiality agreement without standstill provisions
substantially similar to those in the Confidentiality Agreement, then Parent
shall to the extent of such difference be relieved of compliance with the
Confidentiality Agreement's standstill obligations) and (z) the Company shall
have delivered to Parent a prior written notice advising Parent that it intends
to take such action.

                                      A-32
<PAGE>

immediately and cause to be terminated all activities, discussions and
negotiations, if any, with any Persons conducted prior to the date hereof with
respect to any Acquisition Proposal.

    SECTION 6.04.  AFFILIATES.  Prior to the Effective Time, the Company shall
cause to be delivered to Parent a letter identifying, to the best of the
Company's knowledge, all Persons who may be deemed "affiliates" of the Company
under Rule 145 of the 1933 Act. The Company shall use its reasonable best
efforts to cause each Person who is so identified as an affiliate to deliver to
Parent on or prior to the Effective Time a letter substantially in the form of
Exhibit A to this Agreement.

    (a) For six years after the Effective Time, the Surviving Corporation shall
indemnify and hold harmless each present and former officer and director of the
Company and of any Subsidiary of the Company (each, an "INDEMNIFIED PERSON") in
respect of acts or omissions occurring at or prior to the Effective Time to the

provided under the Company's certificate of incorporation and bylaws in effect
on the date hereof; PROVIDED that such indemnification shall be subject to any

acceptable to the Surviving Corporation and the Surviving Corporation shall
cooperate in the defense thereof; PROVIDED that the Surviving Corporation shall
not be liable for the fees of more than one counsel for all Indemnified Persons,
other than local counsel, unless a conflict of interest shall be caused thereby,

settlement effected without its written consent (which consent shall not be
unreasonably withheld).

    (c) For six years after the Effective Time, the Surviving Corporation shall
provide officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time covering each such Indemnified
Person currently covered by the Company's officers' and directors' liability
insurance policy on terms with respect to coverage and amount no less favorable

annual premium equal to 200% of such rate.

    (d) If Parent, the Surviving Corporation or any of its successors or assigns
(i) consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any Person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of Parent or
the Surviving Corporation, as the case may be, shall assume the obligations set

    (e) The rights of each Indemnified Person under this Section 7.04 shall be
in addition to any rights to indemnification, exculpation from liabilities for
acts or omissions or other rights such Person may have under the certificate of
incorporation or bylaws of the Company or any of its Subsidiaries, or under

arrangements with the Company or its Subsidiaries. These rights shall survive
consummation of the Merger and are intended to benefit, and shall be enforceable
by, each Indemnified Person.

    (f) The obligations of the Surviving Corporation under this Section 7.04
shall be joint and several obligations of Parent and the Surviving Corporation.

    SECTION 7.05.  EMPLOYEE MATTERS.  (a) EXISTING EMPLOYMENT AND SEVERANCE
AGREEMENTS. From and after the Effective Time Parent shall, or shall cause the
Surviving Corporation to, without further action, assume and honor the
obligations of the Company and its Subsidiaries under the terms of each written
employment and severance agreement in effect immediately prior to the Effective
Time between the Company or any of its Subsidiaries and any employee or former
employee thereof.

Corporation to, honor all obligations under all severance agreements and
arrangements referred to in Sections 7.05(b)(i) and 7.05(b)(ii) of the Company
Disclosure Schedule.

    (c)  EMPLOYEE BENEFIT LEVELS.  For one year after the Effective Time, Parent
shall, or shall cause the Surviving Corporation to provide employees of the
Company or its Subsidiaries immediately prior to the Effective Time ("AFFECTED
EMPLOYEES") with benefits substantially comparable, in the aggregate, to the
benefits available to Affected Employees immediately prior to the Effective Time
(taking into account, whether or not implemented as of the Effective Time, the
changes to the Company's benefit plans described in Section 7.05(c) of the
Company Disclosure Schedule). In addition to the foregoing requirement, on and
after the first anniversary of the Effective Time, Parent shall, or shall cause
the Surviving Corporation to, provide Affected Employees with benefits
substantially comparable, in the aggregate, to the benefits provided similarly
situated employees of Parent or its Affiliates. In addition, Parent shall, or
shall cause the Surviving Corporation to, maintain in effect during the period
from the Effective Time until the first anniversary of the Effective Time for
the benefit of Affected Employees the severance plans, policies and practices of
the Company and its Subsidiaries applicable to Affected Employees as in effect
immediately prior to the Effective Time.

    (d)  HONORING ACCRUED AND VESTED BENEFITS.  Parent shall, or shall cause the
Surviving Corporation to, honor all accrued, vested benefits under all
compensation and benefit plans, policies, practices and arrangements of the
Company or its Subsidiaries in existence immediately prior to the Effective
Time. Without limiting the generality of the foregoing, Parent shall, or shall
cause the Surviving Corporation to, honor all unused vacation, holiday, sickness
and personal days accrued by Affected Employees under the policies and practices
of the Company and its Subsidiaries.

    (e)  SERVICE CREDIT.  In the event of any change in the welfare benefits
provided to an Affected Employee under any plan, Parent shall, or shall cause
the Surviving Corporation to, (i) waive all limitations as to preexisting
conditions, exclusions and waiting periods with respect to participation and
coverage requirements applicable to the Affected Employee under such plan
(except to the extent that such conditions, exclusions or waiting periods would
apply under the Company or Subsidiary's then existing plans absent any change in
such welfare plan coverage) and (ii) provide each Affected

                                      A-35
<PAGE>
Employee with credit for any co-payments and deductibles paid prior to any such
change in coverage in satisfying any applicable deductible or out-of-pocket
requirements under such new or changed plan. Parent shall, or shall cause the
Surviving Corporation to, provide each Affected Employee with credit for all
service with the Company and its Affiliates under each employee benefit plan,
policy, program or arrangement in which such Affected Employee is eligible to
participate, except to the extent that it would result in a duplication of
benefits with respect to the same period of services. However, neither Parent
nor the Surviving Corporation shall be required to provide past service credit
for benefit accrual purposes (other than under any vacation, sick pay or
severance plan), unless such past service credit is given to other similarly
situated employees.

    (f)  ANNUAL BONUSES.  On or prior to March 15, 2000, without duplicating any
benefits under any severance, termination or employment agreement, Parent shall,
or shall cause the Surviving Corporation to, pay to each Affected Employee then
employed by Parent, the Surviving Corporation or any of their respective
Affiliates who currently participates in the Company's bonus plans, and each
such Affected Employee whose employment was involuntarily terminated without
"cause" by Parent, the Surviving Corporation or any of their respective
Affiliates after the Effective Time but prior to March 15, 2000, a cash bonus
equal to the amount to which such Affected Employee would have been entitled
under the terms of such plans, PROVIDED that the performance measures used to
determine whether an Affected Employee is eligible for such bonus shall be
adjusted to exclude extraordinary expenses arising from the transactions
contemplated by the Agreement. In the event an Affected Employee whose
employment is terminated in 1999 is entitled to a bonus pursuant to this
Section 7.05(f), such bonus shall be pro rated to reflect the portion of
calendar 1999 elapsed between January 1, 1999 and the date of such employee's
termination. A termination will be deemed to be involuntary and without "cause"
if the Affected Employee is terminated in a manner that entitles such person to
severance benefits under the Tier I or Tier II Severance Agreement or Tier III
or Tier IV severance or similar arrangement or agreement for which he or she is
eligible, or the Affected Employee terminates his or her employment after (i) a
material reduction in the level of such Affected Employee's compensation and
benefits, taken in the aggregate; (ii) an assignment of duties substantially
different from his or her current duties and incompatible with such Affected
Employee's education, training and experience; (iii) a relocation of such
Affected Employee's principal workplace by more than 50 miles; or (iv) the
occurrence of any event, fact or circumstance entitling such Affected Employee
to receive severance benefits under any severance or employment agreement.

    Without limiting the generality of the immediately preceding paragraph,
Parent shall not, and shall cause the Surviving Corporation not to, adversely
modify, impair or diminish the ability of any Affected Employee to attain such
Affected Employee's full bonus opportunity for 1999 afforded by any relevant
bonus plan in effect as of the Effective Time.

    (g) Nothing in this Agreement shall be construed to restrict the ability of
Parent and its Subsidiaries to make hiring, promotion or termination decisions
after the Effective Time or to prevent changes in compensation or benefits as
may result due to changes in title, position or responsibility.

    SECTION 7.06.  PARENT BOARD OF DIRECTORS.  Prior to the Effective Time, the
Board of Directors of Parent shall take all action necessary to appoint 2
persons, selected by Parent, who are currently directors of the Company (the
"COMPANY DESIGNEES") to the Board of Directors of Parent as of the Effective
Time.

    SECTION 7.07.  PARENT STOCKHOLDER MEETING.  Parent shall cause a meeting of
its stockholders (the "PARENT STOCKHOLDER MEETING") to be duly called and held
as soon as reasonably practicable for the purpose of voting on the approval and
adoption of this Agreement and the Merger, and, at such stockholder meeting, the
Board of Directors of Parent shall recommend approval and adoption by Parent's
stockholders of this Agreement and the Merger and shall not withdraw such
recommendation. In connection with such meeting, Parent will (i) promptly
prepare and file with the SEC, will use its reasonable best efforts to have
cleared by the SEC and will thereafter mail to its stockholders as promptly as
practicable the Joint Proxy Statement and all other proxy materials for such
meeting,

                                      A-36
<PAGE>
(ii) use its reasonable best efforts to obtain the necessary approvals by its
stockholders of this Agreement and the transactions contemplated hereby and
(iii) otherwise comply with all legal requirements applicable to such meeting.

    SECTION 7.08.  REGISTRATION STATEMENT.  Parent shall promptly prepare and
file with the SEC under the 1933 Act the Registration Statement, and shall use
its reasonable best efforts to cause the Registration Statement to be declared
effective by the SEC as promptly as practicable. Parent shall promptly take any
action required to be taken under foreign or state securities or Blue Sky laws
in connection with the issuance of Parent Stock in the Merger and upon the
exercise of Parent Stock Options.

    SECTION 7.09.  STOCK EXCHANGE LISTING.  Parent shall use its reasonable best
efforts to cause the shares of Parent Stock to be issued in connection with the
Merger to be listed on the NYSE and the Pacific Stock Exchange, subject to
official notice of issuance.

    SECTION 7.10.  TAX-FREE NATURE OF DISTRIBUTION.  Parent will not take any
action or fail to take any action which in the opinion of Gibson, Dunn &
Crutcher LLP or other nationally recognized tax counsel selected by Parent may
cause the Distribution to fail to be qualified as a tax-free transaction under
Section 355(a) and (c) of the Code.

    SECTION 7.11.  FINANCING AGREEMENTS.  (a) Parent shall use its best efforts
to obtain financing in an amount at least equal to the Required Cash Amount,
including by (i) executing before December 2, 1999 (or such later date as agreed
by Bank of America) definitive agreements for the New Senior Credit Facilities
(as defined in the Commitment Letter) contemplated by the Commitment Letter and
(ii) executing as promptly as practicable any necessary amendments, waivers or
other modifications to the Existing Senior Credit Facility. The Commitment
Letter, the definitive agreements for the New Senior Credit Facilities and the
Existing Senior Credit Facility, as so amended, modified or waived (along with
any other document pursuant to which Parent obtains financing of all or a
portion of the Required Cash Amount) are referred to herein collectively as the
"FINANCING AGREEMENTS". The Company will be afforded a reasonable opportunity to
review and comment on the representations and warranties contained in the
Financing Agreements and no such representation or warranty, insofar as it
relates to facts and circumstances relating to the Company and its Subsidiaries,
shall be included therein that the Company shall have advised Parent is
incorrect or inaccurate. Parent shall use its reasonable best efforts to ensure
that the representations and warranties contained in the Financing Agreements
shall be consistent with the Commitment Letter.

    (b) Without limiting the generality of the foregoing, in the event that at
any time funds are not or have not been made available under the Financing
Agreements so as to enable Parent to proceed with the Closing in a timely
manner, Parent shall (i) use its best efforts to obtain alternative funding in
an amount at least equal to the Required Cash Amount on terms and conditions
materially comparable to those provided in such Financing Agreements or
otherwise on terms reasonably acceptable to Parent and (ii) shall continue to
use its reasonable best efforts to take, or cause to be taken, all actions and
to do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate the transactions contemplated by
this Agreement.

    (c) Parent shall take all actions necessary to enforce any or all of its
rights, and comply with all of its obligations under the Financing Agreements,
except to the extent consented to by the Company in writing.

Surviving Corporation any and all right, title and interest in, to and under any
of the rights, properties or assets of the Company acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger.

    SECTION 8.05.  ACCESS TO INFORMATION.  From the date hereof until the

<PAGE>
counsel, financial advisors, auditors and other authorized representatives to
cooperate with the other party in its investigation. Any investigation pursuant
to this Section shall be conducted in such manner as not to interfere
unreasonably with the conduct of the business of the other party. Unless
otherwise required by law, each of Company and Parent will hold, and will cause
its respective officers, employees, counsel, financial advisors, auditors and

made by any party hereunder.

    SECTION 8.06.  NOTICES OF CERTAIN EVENTS.  Each of the Company and Parent
shall promptly notify the other of:

    (a) any notice or other communication from any Person alleging that the
consent of such Person is or may be required in connection with the transactions
contemplated by this Agreement;

pursuant to Section 4.12, 4.13, 5.12 or 5.13, as the case may be, or that relate
to the consummation of the transactions contemplated by this Agreement.

    SECTION 8.07.  COOPERATION AS TO TAX MATTERS.  Each of the Company and
Parent will (a) not take any action that is reasonably likely to cause the
Merger to fail to qualify as a "reorganization" within the meaning of
Section 368 of the Code, and (b) use its reasonable best efforts (including the
provision of customary representations) to permit counsel to render the opinions
described in Section 9.02(b) and Section 9.03(b). Neither Parent nor the Company
shall take or cause to be taken any action which would cause to be untrue (or
fail to take or cause not to be taken any action which would cause to be untrue)
any of the representations set forth in certificates delivered to such counsel.

    SECTION 8.08.  TRANSFER AND GAINS TAX.  Parent will pay any federal, state,

Gains Taxes, payable in connection with the consummation of the Merger, (except
as otherwise provided in Section 2.10) any federal, state, local, foreign or
provincial tax which is attributable to the transfer of Shares or Parent Stock
pursuant to the terms of this Agreement (collectively, "STOCK TRANSFER TAXES")
and any penalties or interest with respect to any such Stock Transfer Taxes.
Parent and the Company agree to cooperate with the other in the filing of any
returns with respect to the Gains Taxes, including supplying in a timely manner
a complete list of all real property interests held by the Company and its
Subsidiaries and any information with respect to such property that is
reasonably necessary to complete such returns. The portion of the consideration
allocable to the real property of the Company and its Subsidiaries shall be
agreed to between Parent and the Company. The stockholders of the Company shall
be deemed to have agreed to be bound by the allocation established pursuant to
this Section 8.08 in the preparation of any return with respect to the Gains
Taxes.

reasonable best efforts to cause to be delivered to the other party and such
other party's directors a letter of its independent auditors, dated the date on

other party and such other party's directors, in form and substance customary
for "comfort" letters delivered by independent public accountants in connection
with registration statements similar to the Registration Statement.

    (b) by either the Company or Parent, if:

        (i) the Merger has not been consummated on or before the Outside
    Termination Date. The "OUTSIDE TERMINATION DATE" shall mean March 31, 2000;
    PROVIDED however that if by such date the condition set forth in
    Section 9.02(c) has not been satisfied solely because the lenders under the
    Financing Agreements have declined to provide funds thereunder because of a
    material adverse change in or material disruption of conditions in the
    financial, banking or capital markets related to the "Year 2000 Problem"
    (that is, the risk that computer software and systems may be unable to
    recognize and perform date-sensitive functions involving certain dates prior

        (ii) there shall be any law or regulation that makes consummation of the
    Merger illegal or otherwise prohibited or any judgment, injunction, order or
    decree of any court or governmental

                                      A-41
<PAGE>
    body having competent jurisdiction enjoining Company or Parent from
    consummating the Merger is entered and such judgment, injunction, judgment

    to terminate this Agreement pursuant to this Section 10.01(b)(ii) shall not
    be available to any party whose breach of any provision of this Agreement
    results in the application of any such law or regulation to the Merger or
    the imposition of any such judgment, injunction, order or decree;

        (iii) this Agreement shall not have been approved and adopted in
    accordance with Delaware Law by the Company's stockholders at the Company
    Stockholder Meeting (or any adjournment thereof); or

    Act), other than Parent or any of its Affiliates, shall have acquired
    beneficial ownership of more than 50% of the Shares;

        (ii) (A) the Board of Directors of the Company shall have failed to
    recommend or withdrawn, or modified in a manner adverse to Parent, its
    approval or recommendation of this Agreement or the Merger and shall have
    approved or recommended a Superior Proposal, or (B) the Company shall have
    entered into, or publicly announced its intention to enter into, a
    definitive agreement or an agreement in principle with respect to a Superior
    Proposal; or

    (d) by the Company, if

        (i) the Board of Directors of the Company shall approve a Superior
    Proposal or shall withdraw, or modify in a manner adverse to Parent, its
    recommendation of this Agreement or the Merger to its stockholders, provided
    however that (A) the Company shall have complied with Section 6.02(b) and
    Section 6.03, (B) the Company shall have given Parent five business days
    written prior notice of its intention to terminate the Agreement, attaching
    a description of all material terms and conditions of the Superior Proposal
    to such notice, (C) Parent does not make prior to such termination of this
    Agreement a definitive, binding offer to make adjustments to this Agreement
    which the Board of Directors of the Company determines would enable the
    Company to proceed with its recommendation to its stockholders of the
    transactions contemplated hereby as amended by such proposed adjustments,
    and (D) the Company prior to such termination pursuant to this
    clause (d)(i) pays to Parent in immediately available funds the fee required
    to be paid pursuant to Section 11.04(b). The Company agrees to notify Parent
    promptly if its intention to enter into a written agreement referred to in
    its notification shall change at any time after giving such notification; or

        (ii) if the Board of Directors of Parent shall have failed to recommend

(other than pursuant to Section 10.01(a)) shall give notice of such termination
to the other party.

    SECTION 10.02.  EFFECT OF TERMINATION.  If this Agreement is terminated
pursuant to Section 10.01, this Agreement shall become void and of no effect
with no liability on the part of any party (or any stockholder, director,
officer, employee, agent, consultant or representative of such party) to the
other party hereto; PROVIDED that, if such termination shall result from the
willful (i) failure of either party to fulfill a condition to the performance of
the obligations of the other party, (ii) failure of either party to perform a
covenant hereof or (iii) breach by either party hereto of any representation or
warranty or agreement contained herein, such party shall be fully liable for any
and all liabilities and damages incurred or suffered by the other party as a
result of such failure or breach. The provisions of Sections 11.04, 11.06, 11.07
and 11.08 shall survive any termination hereof pursuant to Section 10.01.

                 FORM OF RULE 145 LETTER FOR COMPANY AFFILIATES

                                                                       [Date]

Hilton Hotels Corporation

Beverly Hills, CA 90210

Promus Hotel Corporation
755 Crossover Lane
Memphis, TN 98031

Ladies and Gentlemen:

    The undersigned has been advised that, as of the date of this letter, the
undersigned may be deemed to be an "affiliate" of Promus Hotel Corporation, a
Delaware corporation (the "COMPANY"), as the term "affiliate" is defined for
purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the
"RULES AND REGULATIONS") of the Securities and Exchange Commission (the "SEC")
under the Securities Act of 1933, as amended (the "1933 ACT"). Pursuant to the
terms of the Agreement and Plan of Merger dated as of September 3, 1999 (the
"MERGER AGREEMENT") among the Company, Hilton Hotels Corporation, a Delaware
corporation ("PARENT"), and Chicago Hilton, Inc., a Delaware corporation and
wholly-owned subsidiary of Parent ("MERGER SUBSIDIARY"), the Company will be
merged with and into Merger Subsidiary with Merger Subsidiary to be the
surviving corporation in the merger (the "MERGER").

    As a result of the Merger, the undersigned will receive shares of common
stock, par value $2.50 per share, of Parent ("PARENT STOCK") in exchange for
shares owned by the undersigned of common stock, par value $0.01, of the Company
(the "COMPANY COMMON STOCK"), or options, warrants or other rights to acquire
Parent Stock.

    The undersigned represents, warrants and covenants to Parent and the Company
that, as of the date the undersigned receives any Parent Stock (including
through exercise of any options, warrants or other rights) as a result of the
Merger:

    A. The undersigned shall not make any sale, transfer or other disposition of
the Parent Stock in violation of the 1933 Act or the Rules and Regulations.

    B. The undersigned has carefully read this letter and reviewed the principal
terms of the Merger Agreement and discussed the requirements of such documents
and other applicable limitations upon the undersigned's ability to sell,
transfer or otherwise dispose of Parent Stock, to the extent the undersigned
felt necessary, with the undersigned's counsel or counsel for the Company.

    C. The undersigned has been advised that the issuance of Parent Stock to the
undersigned pursuant to the Merger will be registered with the SEC under the
1933 Act on a Registration Statement on Form S-4. However, the undersigned has
also been advised that, because, at the time the Merger is submitted for a vote
of the stockholders of the Company, the undersigned may be deemed an affiliate
of the Company, the undersigned may not sell, transfer or otherwise dispose of
Parent Stock issued to the undersigned in the Merger (including through the
exercise of any options, warrants or other rights) unless (i) such sale,
transfer or other disposition has been registered under the 1933 Act, (ii) such
sale, transfer or other disposition is made in conformity with Rule 145
promulgated by the SEC under the 1933 Act, or (iii) in the opinion of counsel
reasonably acceptable to Parent, or

                                      A-47
<PAGE>
pursuant to a "no action" letter obtained by the undersigned from the SEC staff,
such sale, transfer or other disposition is otherwise exempt from registration
under the 1933 Act.

    D. The undersigned understands that Parent is under no obligation to
register the sale, transfer or other disposition of the Parent Stock by the
undersigned or on the undersigned's behalf under the 1933 Act or to take any
other action necessary in order to enable the undersigned to make such sale,
transfer or other disposition in compliance with an exemption from such
registration.

    E. The undersigned also understands that there will be placed on the
certificates for the Parent Stock issued to the undersigned, or on any
substitutions therefor, a legend stating in substance:

       "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
       TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
       1933 APPLIES. THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE SOLD,
       TRANSFERRED OR OTHERWISE DISPOSED OF ONLY IN ACCORDANCE WITH THE TERMS OF
       A LETTER AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND HILTON HOTELS
       CORPORATION, A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL
       OFFICES OF HILTON HOTELS CORPORATION."

    F. The undersigned also understands that, unless the transfer by the
undersigned of the undersigned's Parent Stock (including any Parent Stock
acquired pursuant to the exercise of any options, warrants or other rights) has
been registered under the 1933 Act or is a sale made in conformity with the
provisions of Rule 145, Parent reserves the right to put the following legend on
the certificates issued to the undersigned's transferee:

       "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
       UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
       RECEIVED SUCH SECURITIES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED
       UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SECURITIES HAVE NOT BEEN
       ACQUIRED BY THE HOLDER WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH,
       ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933
       AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT
       TO AN EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN EXEMPTION
       FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."

It is understood and agreed that the legends set forth in paragraphs E and F
above shall be removed by delivery of substitute certificates without such
legend if (i) the securities represented thereby have been registered for sale
by the undersigned under the 1933 Act or (ii) Parent has received either an
opinion of counsel, which opinion and counsel shall be reasonably satisfactory
to Parent, or a "no-action" letter obtained by the undersigned from the SEC
staff to the effect that the restrictions imposed by Rule 145 under the 1933 Act
no longer apply to the undersigned.

    G. The undersigned further understands and agrees that the representations,
warranties, covenants and agreements of the undersigned set forth herein are for
the benefit of Parent, the Company and the Surviving Corporation (as defined in
the Merger Agreement) and will be relied upon by such firms and their respective
counsel and accountants.

    H. The undersigned understands and agrees that this letter agreement shall
apply to all shares of the capital stock of Parent and the Company that are
deemed beneficially owned by the undersigned pursuant to applicable federal
securities laws and which were directly or indirectly acquired by the
undersigned as a result of the consummation of the transactions contemplated by
the Merger Agreement.

    Execution of this letter should not be considered an admission on the part

such an affiliate on or after the date of this letter.

                                                          September 7, 1999

Board of Directors
Hilton Hotels Corporation
9336 Civic Center Drive
Beverly Hills, CA 90210

Members of the Board:

We understand that Promus Hotel Corporation (the "Company"), Hilton Hotels
Corporation ("Buyer") and Chicago Hilton, Inc., a wholly owned subsidiary of
Buyer ("Acquisition Sub"), propose to enter into an Agreement and Plan of
Merger, substantially in the form of the draft dated as of September 3, 1999
(the "Merger Agreement"), which provides for, among other things, the merger of
the Company with Acquisition Sub (the "Merger"). You have advised us that in its
final form, the Merger Agreement contemplates an alternative possibility as to
the mechanics of the Merger (not reflected in the September 3 draft referred to
above) depending upon future circumstances, in order to minimize adverse effects
of the Merger under certain existing contracts. You have further advised that
such alternative would not adversely affect Buyer in any material respect.
Pursuant to the Merger, other than shares of Company Common Stock held in
treasury or held by any Subsidiary (as defined in the Merger Agreement) of the
Company or by Buyer or any of its Subsidiaries or as to which appraisal rights
have been perfected, 55% of the outstanding shares of common stock, par value
$.01 per share of the Company (the "Company Common Stock") will be converted
into the right to receive $38.50 per share in cash, and 45% of the outstanding
shares of Company Common Stock will be converted into the right to receive the
number of shares of common stock, par value $2.50 per share of Buyer (the "Buyer
Common Stock) equal to the Exchange Ratio (as defined below). You have advised
us that under the alternative mechanics referred to above, common stock of a new
holding company could be substituted for Company Common Stock. The "Exchange
Ratio" is defined in the Merger Agreement as the number (rounded to the nearest
ten-thousandth) determined by dividing $38.50 by the Market Price per share of
Buyer Common Stock; provided, that in no event shall the Exchange Ratio be
(x) greater than 3.2158 or (y) less than 2.9096. The "Market Price" per share of
Buyer Common Stock is defined in the Merger Agreement as the average of the
volume weighted average per share sales price of Buyer Common Stock on the New
York Stock Exchange, Inc. for twenty trading days selected by lot out of the
thirty trading days ending on and including the fifth trading day prior to the
Effective Time (as defined in the Merger Agreement). The terms and conditions of
the Merger are more fully set forth in the Merger Agreement and are incorporated
herein by reference.

You have asked for our opinion as to whether the consideration to be paid by
Buyer pursuant to the Merger Agreement is fair from a financial point of view to
Buyer.

For purposes of the opinion set forth herein, we have:

    (i) reviewed certain publicly available financial statements and other
        information of the Company and Buyer;

    (ii) reviewed certain internal financial statements and other financial and
         operating data concerning the Company prepared by the management of the
         Company;

   (iii) reviewed certain financial projections prepared by the management of
         the Company;

    (iv) discussed the past and current operations and financial condition and
         the prospects of the Company, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Merger, with senior executives of the Company;

                                      B-1
<PAGE>
    (v) discussed the past and current operations and financial condition and
        the prospects of the Company, including information relating to certain
        strategic financial and operational benefits anticipated from the merger
        with senior executives of Buyer;

    (vi) reviewed certain internal financial statements and other financial and
         operating data concerning Buyer prepared by the management of Buyer;

   (vii) reviewed certain financial projections prepared by the management of
         Buyer;

  (viii) discussed the past and current operations and financial condition and
         the prospects of Buyer, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Merger, with senior executives of Buyer;

    (ix) reviewed with senior executives of Buyer the pro forma impact of the
         Merger on Buyer's earnings per share, consolidated capitalization and
         financial ratios;

    (x) reviewed the reported prices and trading activity for the Company Common
        Stock and the Buyer Common Stock;

    (xi) compared the financial performance of the Company and the prices and
         trading activity of the Company Common Stock with those of certain
         other comparable publicly traded companies and their securities;

   (xii) compared the financial performance of Buyer and the prices and trading
         activity of the Buyer Common Stock with those of certain other
         comparable publicly traded companies and their securities;

  (xiii) reviewed the financial terms, to the extent publicly available, of
         certain comparable acquisition transactions;

   (xiv) participated in discussions and negotiations among representatives of
         the Company and Buyer and their financial and legal advisors;

   (xv) reviewed the draft Merger Agreement and certain related documents; and

   (xvi) performed such other analyses and considered such other factors as we
         have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy
and completeness of the information reviewed by us for the purposes of this
opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the Merger, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company and Buyer. We have also relied upon,
without independent verification, the assessment of Buyer of the strategic,
financial and operational benefits expected to result from the Merger. In
addition, we have assumed that the Merger will be consummated in accordance with
the terms set forth in the Merger Agreement. We have not made any independent
valuation or appraisal of the assets or liabilities of the Company, nor have we
been furnished with any such appraisals. Our opinion is necessarily based on
financial, economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.

We have acted as financial advisor to the Board of Directors of Buyer in
connection with this transaction and will receive a fee for our services,
including possibly fees for providing financing services in connection with this

and its affiliates have provided financial advisory and financing services to
Doubletree Corporation, which merged with the Company, and have received fees
for its services.

It is understood that this letter is for the information of the Board of
Directors of Buyer and may not be used for any other purpose without our prior
written consent, except that this letter may be included in its entirety in any
filing made by the Buyer with the Securities and Exchange Commission in
connection with the Merger. In addition, this opinion does not in any manner
address the prices at which the Buyer Common Stock will trade following
consummation of the Merger, and Morgan Stanley expresses no opinion or
recommendation as to how shareholders of the Company and Buyer should vote at
the shareholders meetings to be held in connection with the Merger.

Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the consideration to be paid by Buyer pursuant to the Merger
Agreement is fair from a financial point of view to Buyer.

                                          Very truly yours,

                                                          September 7, 1999

Board of Directors
Hilton Hotels Corporation
9336 Civic Center Drive
Beverly Hills, CA 90210
Dear Sirs:

    You have requested our opinion as to the fairness from a financial point of
view to Hilton Hotels Corporation (the "Company") and its stockholders of the
consideration to be paid by the Company pursuant to the terms of the Agreement
and Plan of Merger, dated as of September 3, 1999 (the "Agreement"), by and
among the Company, Promus Hotel Corporation ("Promus") and Chicago
Hilton, Inc., a wholly owned subsidiary of the Company ("Merger Subsidiary"),
pursuant to which Promus will be merged with and into Merger Subsidiary (or in
certain circumstances, Merger Subsidiary shall be merged with and into Promus)
(the "Merger"). We understand that the Agreement contemplates an alternative
possibility as to the mechanics of the Merger depending upon future
circumstances, in order to minimize adverse effects of the Merger under certain
existing contracts. You have advised that such alternative would not adversely
affect the Company or Promus in any material respect.

    Pursuant to the Agreement, each share of common stock, $.01 par value
("Promus Stock"), of Promus will be converted into the right to receive, at the
election of the holder (subject to the limitations below) (the "Cash Election"
and the "Stock Election," respectively) either (i) $38.50 in cash (the "Cash
Consideration") or (ii) the number of shares of common stock, $2.50 par value
("Company Stock"), of the Company equal to the Exchange Ratio (as defined below)
(the "Stock Consideration" and together with the Cash Consideration, the "Merger
Consideration"). The "Exchange Ratio" shall be a number of shares determined by
dividing $38.50 by the Market Price (as defined below) per share of the Company
Stock; PROVIDED, HOWEVER, that in no event shall the Exchange Ratio be greater
than 3.2158 or less than 2.9096. The "Market Price" per share of the Company
Stock shall be the average of the volume weighted average per share sales price
of the Company Stock on the New York Stock Exchange, Inc. for twenty trading
days selected by lot out of the thirty trading days ending on and including the
fifth day prior to the effective date of the Merger. If Cash Elections exceed
55% of the aggregate shares of Promus Stock, shares for which cash elections
have been received will receive prorated Cash and Stock Consideration, such that
the aggregate Cash Consideration equals 55% of the total Merger Consideration.
If Stock Elections exceed 45% of the aggregate shares of Promus Stock, shares
for which Stock Elections have been received will receive prorated Stock and
Cash Consideration, such that the aggregate Stock Consideration equals 45% of
the total Merger Consideration. You have advised us that under the alternative
mechanics of the Merger referred to above, common stock of a new holding company
with minimal operations and whose sole assets are its interests in the Company
and Promus could be substituted for Company Stock.

    In arriving at our opinion, we have reviewed the Agreement dated as of
September 3, 1999. We also have reviewed financial and other information that
was publicly available or furnished to us by the Company and Promus including
information provided during discussions with their respective management.
Included in the information provided during discussions with the respective
managements were certain financial projections of Promus for the period
beginning July 31, 1999 and ending December 31, 2003 prepared by the management
of Company and certain financial projections of the Company for the period
beginning July 31, 1999 and ending December 31, 2003 prepared by the management
of the Company. In addition, we have compared certain financial and securities
data of the Company and Promus with various other companies whose securities are
traded in public markets, reviewed the historical stock prices and trading
volumes of the common stock of Promus and the Company, reviewed prices and
premiums paid in certain other business combinations and conducted

                                      C-1
<PAGE>
such other financial studies, analyses and investigations as we deemed
appropriate for purposes of this opinion. We have also assumed that the Merger
will result in no corporate level taxation for the Company or Promus.

    In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
us from public sources, that was provided to us by the Company and Promus or
their respective representatives, or that was otherwise reviewed by us. In
particular, we have relied upon the estimates of the management of the Company
of the operating synergies achievable as a result of the Merger and upon our
discussion, with your knowledge, of such synergies with the management of
Promus. With respect to the financial projections supplied to us, we have relied
on representations that they have been reasonably prepared on the basis
reflecting the best currently available estimates and judgments of the
management of the Company as to the future operating and financial performance
of the Company and Promus. We have not assumed any responsibility for making any
independent evaluation of any assets or liabilities or for making any
independent verification of any of the information reviewed by us.

    Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion as to the prices
at which Company Stock will actually trade at any time. Our opinion does not
address the relative merits of the Merger and the other business strategies
being considered by the Company's Board of Directors, nor does it address the
Board's decision to proceed with the Merger. Our opinion does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed transaction or as to what election regarding form of consideration any
such stockholder should make.

    Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. DLJ has performed investment
banking and other services for the Company in the past and has been compensated
for such services. DLJ co-managed $200 million of Senior Notes due 2009 and
$200 million of Senior Notes due 2017 for the Company in December 1997,
lead-managed a $773 million follow-on offering of the Company's common stock in
April 1998, delivered a fairness opinion to the Company in connection with a
spin-off of its gaming assets to its shareholders and the simultaneous
acquisition of the gaming business of Grand Casinos, Inc. in June 1998 and acted
as dealer manager and lead consent solicitation agent for Park Place
Entertainment Corporation, a wholly owned subsidiary of the Company at the time,
in connection with a tender offer and consent solicitation for $450 million of
Grand Casinos' First Mortgage Notes due 2003 in December 1998. DLJ received
usual and customary compensation in connection with these transactions.

    Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the Merger Consideration to be paid by the Company pursuant
to the Agreement is fair to the Company and its stockholders from a financial
point of view.

                                          Very truly yours,

Board of Directors
Promus Hotel Corporation
755 Crossover Lane
Memphis, TN 38117

Members of the Board:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the common stock of Promus Hotel Corporation (the
"Company") of the consideration to be received by such holders pursuant to an
Agreement and Plan of Merger (the "Merger Agreement") dated as of September 3,
1999, by and among the Company, Hilton Hotels Corporation ("Parent") and Chicago
Hilton, Inc. ("Merger Subsidiary"). As more fully described in the Merger
Agreement, (i) the Company and Merger Subsidiary will merge (the "Merger") and
(ii) each outstanding share of the common stock, par value $0.01 per share, of
the Company (the "Company Common Stock") (other than shares held by the Company,
Parent or Merger Subsidiary) will be converted into the right to receive, at the
election of the holder thereof and subject to proration, either (A) $38.50 in
cash (the "Cash Consideration") or (B) that number of shares (rounded to the
nearest ten-thousandth) of the common stock, par value $2.50 per share, of
Parent (the "Parent Common Stock") determined by dividing $38.50 by the Market
Price (as defined below) of the Common Stock (the "Exchange Ratio"); PROVIDED,
HOWEVER, that in no event shall the Exchange Ratio be (x) greater than 3.2158 or
(y) less than 2.9096. Alternatively, pursuant to the Merger Agreement, the
parties may agree to implement the Alternative Double Merger Structure (as
defined in the Merger Agreement), in which case you have advised us that
(i) each outstanding share of Company Common Stock will be converted into the
right to receive, at the election of the holder thereof and subject to
proration, either (A) the Cash Consideration or (B) that number of shares
(rounded to the nearest ten-thousandth) of the common stock (the "New Hilton
Common Stock") of a new holding company ("New Hilton") equal to the Exchange
Ratio, (ii) each outstanding share of Parent Common Stock will be converted into
one share of New Hilton Common Stock and (iii) each of the Company and Parent
will become wholly owned subsidiaries of New Hilton. The "Market Price" per
share of Parent Common Stock shall be the average of the volume weighted average
per share sales price of Parent Common Stock on the New York Stock
Exchange, Inc. for twenty trading days selected by lot out of the thirty trading
days ending on and including the fifth trading day prior to the effective time
of the Merger. In this opinion, the term "Merger Consideration" means (i) if the
Alternative Double Merger Structure is not implemented, the Cash Consideration
and the shares of Parent Common Stock, together with cash in lieu of fractional
shares of Parent Common Stock, payable and issuable to the holders of Company
Common Stock and (ii) if the Alternative Double Merger Structure is implemented,
the Cash Consideration and the shares of New Hilton Common Stock payable and
issuable to holders of Company Common Stock.

    In arriving at our opinion, we have reviewed the Merger Agreement, certain
publicly available information concerning the Company and Parent and certain
other financial information concerning the Company and Parent, including
financial forecasts and estimated cost savings and synergies resulting from the
Merger, that were provided to us by the Company and Parent, respectively. We
have discussed the past and current business operations, financial condition and
prospects of the Company and Parent with certain officers and employees of the
Company and Parent, respectively. We have also considered such other
information, financial studies, analyses, investigations and financial, economic
and market criteria that we deemed relevant.

    In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the information reviewed by us for the purpose of this opinion,
and we have not assumed any responsibility

                                      D-1
<PAGE>
for independent verification of such information. With respect to the financial
forecasts of the Company and Parent, we have assumed that they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the managements of the Company and Parent, respectively, as to
the future financial performance of the Company and Parent and we express no
opinion with respect to such forecasts.

    Our opinion, as set forth herein, relates to the relative values of the
Company and Parent. We are not expressing any opinion as to what the value of
the Parent Common Stock or New Hilton Common Stock actually will be when issued
pursuant to the Merger or the price at which the Parent Common Stock or New
Hilton Common Stock will trade subsequent to the Merger. We have not made or
obtained or assumed any responsibility for making or obtaining any independent
evaluation or appraisal of any of the assets (including properties and
facilities) or liabilities of the Company or Parent. We have assumed that the
implementation of the Alternative Double Merger Structure will preserve the
economic and financial terms of the Merger Agreement.

    Our opinion is necessarily based upon conditions as they exist and can be
evaluated on the date hereof. Our opinion does not address the Company's
underlying business decision to effect the proposed Merger, and we express no
view on the effect on the Company of the Merger and related transactions. Our
advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of the Company in its evaluation of the
proposed Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder of the Company as to how such stockholder
should vote on any matters relating to the proposed Merger or whether such
stockholder should elect to receive the Cash Consideration or, as applicable,
Parent Common Stock or New Hilton Common Stock.

    We have acted as financial advisor to the Board of Directors of the Company
in connection with the proposed Merger and will receive a fee for our services,
a significant portion of which is contingent upon the consummation of the
Merger. We are currently providing investment banking services to the Company
and have in the past provided investment banking services to the Company and
Parent, in each case unrelated to the proposed Merger, for which services we
will receive or have received compensation. In the ordinary course of our
business, we and our affiliates may actively trade or hold the securities of the
Company and Parent for our own account or for the account of our customers and,
accordingly, may at any time hold a long or short position in such securities.
In addition, we and our affiliates (including Citigroup Inc. and its affiliates)
may maintain relationships with the Company, Parent and their respective
affiliates.

    Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Consideration is fair, from a financial point of view,
to the holders of Company Common Stock.

                                          Very truly yours,
                                          /s/ SALOMON SMITH BARNEY INC.

                        DELAWARE GENERAL CORPORATION LAW

SECTION 262. APPRAISAL RIGHTS.

    (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to Section 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section 251 (other than a merger effected pursuant to
Section 251(G) of this title), Section 252 Section 254 Section 257 Section 258
Section 263 or Section 264 of this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of Section 251 of this title.

        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to
    SectionSection 251, 252, 254, 257, 258, 263 and 264 of this title to accept
    for such stock anything except:

           a.  Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

           b.  Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock (or depository receipts in
       respect thereof) or depository receipts at the effective date of the
       merger or consolidation will be either listed on a national securities
       exchange or designated as a national market system security on an
       interdealer quotation system by the National Association of Securities
       Dealers, Inc. or held of record by more than 2,000 holders;

           c.  Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or

           d.  Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

                                      E-1
<PAGE>
        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under Section 253 of this title is not owned by
    the parent corporation immediately prior to the merger, appraisal rights
    shall be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections
(d) and (e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsection (b) or (c) hereof that appraisal rights are available
    for any or all of the shares of the constituent corporations, and shall
    include in such notice a copy of this section. Each stockholder electing to
    demand the appraisal of such stockholder's shares shall deliver to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of such stockholder's shares. Such demand will
    be sufficient if it reasonably informs the corporation of the identity of
    the stockholder and that the stockholder intends thereby to demand the
    appraisal of such stockholder's shares. A proxy or vote against the merger
    or consolidation shall not constitute such a demand. A stockholder electing
    to take such action must do so by a separate written demand as herein
    provided. Within 10 days after the effective date of such merger or
    consolidation, the surviving or resulting corporation shall notify each
    stockholder of each constituent corporation who has complied with this
    subsection and has not voted in favor of or consented to the merger or
    consolidation of the date that the merger or consolidation has become
    effective; or

        (2) If the merger or consolidation was approved pursuant to Section 228
    or Section 253 of this title, each consitutent corporation, either before
    the effective date of the merger or consolidation or within ten days
    thereafter, shall notify each of the holders of any class or series of stock
    of such constitutent corporation who are entitled to appraisal rights of the
    approval of the merger or consolidation and that appraisal rights are
    available for any or all shares of such class or series of stock of such
    constituent corporation, and shall include in such notice a copy of this
    section; provided that, if the notice is given on or after the effective
    date of the merger or consolidation, such notice shall be given by the
    surviving or resulting corporation to all such holders of any class or
    series of stock of a constituent corporation that are entitled to appraisal
    rights. Such notice may, and, if given on or after the effective date of the
    merger or consolidation, shall, also notify such stockholders of the
    effective date of the merger or consolidation. Any stockholder entitled to
    appraisal rights may, within 20 days after the date of mailing of such
    notice, demand in writing from the surviving or resulting corporation the
    appraisal of such holder's shares. Such demand will be sufficient if it
    reasonably informs the corporation of the identity of the stockholder and
    that the stockholder intends thereby to demand the appraisal of such
    holder's shares. If such notice did not notify stockholders of the effective
    date of the merger or consolidation, either (i) each such constitutent
    corporation shall send a second notice before the effective date of the
    merger or consolidation notifying each of the holders of any class or series
    of stock of such constitutent corporation that are entitled to appraisal
    rights of the effective date of the merger or consolidation or (ii) the
    surviving or resulting corporation shall send such a second notice to all
    such holders on or within 10 days after such effective date; provided,
    however, that if such second notice is sent more than 20 days following the
    sending of the first notice, such second notice need only be sent

                                      E-2
<PAGE>
    to each stockholder who is entitled to appraisal rights and who has demanded
    appraisal of such holder's shares in accordance with this subsection. An
    affidavit of the secretary or assistant secretary or of the transfer agent
    of the corporation that is required to give either notice that such notice
    has been given shall, in the absence of fraud, be prima facie evidence of
    the facts stated therein. For purposes of determining the stockholders
    entitled to receive either notice, each constitutent corporation may fix, in
    advance, a record date that shall be not more than 10 days prior to the date
    the notice is given, provided, that if the notice is given on or after the
    effective date of the merger or consolidation, the record date shall be such
    effective date. If no record date is fixed and the notice is given prior to
    the effective date, the record date shall be the close of business on the
    day next preceding the day on which the notice is given.

    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all

                                      E-3
<PAGE>
relevant factors, including the rate of interest which the surviving or
resulting corporation would have had to pay to borrow money during the pendency
of the proceeding. Upon application by the surviving or resulting corporation or
by any stockholder entitled to participate in the appraisal proceeding, the
Court may, in its discretion, permit discovery or other pretrial proceedings and
may proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection
(f) of this section and who has submitted such stockholder's certificates of
stock to the Register in Chancery, if such is required, may participate fully in
all proceedings until it is finally determined that such stockholder is not
entitled to appraisal rights under this section.

    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

    Directors to be fixed from time to time solely by resolution adopted by a
    majority of the total number of Directors which the Corporation would have

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law, Article XI of Hilton's
    Certificate of Incorporation, and Paragraph 35 of Hilton's By-Laws, as
    amended, authorize and empower Hilton to indemnify its directors, officers,
    employees and agents, and agreements with each of Hilton's directors and
    executive officers provide for indemnification against liabilities incurred
    in connection with, and related expenses resulting from, any claim, action
    or suit brought against any such person as a result of such person's
    relationship with Hilton, provided that such persons acted in accordance
    with a stated standard of conduct in connection with the acts or events on
    which such claim, action or suit is based. The finding of either civil or
    criminal liability on the part of such persons in connection with such acts
    or events is not necessarily determinative of the question of whether such
    persons have met the required standard of conduct and are, accordingly,
    entitled to be indemnified. Hilton has purchased for the benefit of its
    officers and directors and those of certain subsidiaries insurance policies
    under which the issuing insurance companies agree, among other things, that
    in the event any such officer or director becomes legally obligated to make
    a payment (including legal fees and expenses) in connection with an alleged
    wrongful act, such insurance companies will pay Hilton up to $100,000,000.
    Wrongful act means any breach of duty, neglect, error, misstatement,
    misleading statement or other act done by an officer or director of Hilton
    or any subsidiary.

*  Management contracts or compensatory plans or arrangements required to be
   filed as exhibits to this Registration Statement by Item 601(b)(10)(iii) of
   Regulation S-K, previously filed where indicated and incorporated herein by
   reference.



    Pursuant to Regulation Section 229.601, Item 601(b)(4)(iii) of
Regulation S-K, upon request of the Securities and Exchange Commission, the
Registrant hereby undertakes to furnish a copy of any unfiled instrument which
defines the rights of holders of long-term debt of the Registrant and its
consolidated subsidiaries (and for any of its unconsolidated subsidiaries for
which financial statements are required to be filed) wherein the total amount of
securities authorized thereunder does not exceed 10% of the total consolidated
assets of the Registrant.


ITEM 22.  UNDERTAKINGS.

    The undersigned registrant hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
       post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
            Securities Act of 1933;

        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) that, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in the registration statement. Notwithstanding the foregoing,
             any increase or decrease in volume of securities offered (if the
             total dollar value of securities offered would not exceed that
             which was registered) and any deviation from the low or high end of
             the estimated maximum offering range may be reflected in the form
             of prospectus filed with the Commission pursuant to Rule 424(b) if,
             in the aggregate, the changes in volume and price represent no more
             than 20 percent change in the maximum aggregate offering price set
             forth in the "Calculation of Registration Fee" table in the
             effective registration statement; and

       (iii) To include any material information with respect to the plan of

             or any material change to such information in the registration
             statement.

    (3) To remove from registration by means of a post-effective amendment any

    employee benefit plan's annual report pursuant to Section 15(d) of the
    Securities Exchange Act of 1934) that is incorporated by reference in the
    registration statement shall be deemed to be a new registration statement
    relating to the securities offered therein, and the offering of such
    securities at the time shall be deemed to be the initial BONA FIDE offering
    thereof.

        The undersigned registrant hereby undertakes to deliver or cause to be
    delivered with the prospectus, to each person to whom the prospectus is sent
    or given, the latest annual report, to security holders that is incorporated

    a prospectus which is a part of this registration statement, by any person
    or party who is deemed to be an underwriter within the meaning of
    Rule 145(c), the issuer undertakes that such reoffering prospectus will
    contain the information called for by the applicable registration form with
    respect to reofferings by persons who may be deemed underwriters, in
    addition to the information called for by the other items of the applicable
    form.

        The registrant undertakes that every prospectus: (i) that is filed
    pursuant to the immediately preceding paragraph, or (ii) that purports to
    meet the requirements of Section 10(a)(3) of the Act and is used in
    connection with an offering of securities subject to Rule 415, will be filed
    as a part of an amendment to the registration statement and will not be used
    until such amendment is effective, and that, for purposes of determining any
    liability under the Securities Act of 1933, each such post-effective
    amendment shall be deemed to be a new registration statement relating to the
    securities offered therein, and the offering of such securities at that time
    shall be deemed to be the initial bona fide offering thereof.

        The undersigned registrant hereby undertakes to respond to requests for
    information that is incorporated by reference into the prospectus pursuant
    to Items 4, 10(b), 11, or 13 of this form, within one business day of

        The undersigned registrant hereby undertakes to supply by means of a
    post-effective amendment all information concerning a transaction, and the
    company being acquired involved therein, that was not the subject of and
    included in the registration statement when it became effective.

Company's Common Stock, par value $2.50 per share (the "Shares"), in
connection with the Acquisition. The Company proposes to issue the Shares in
exchange for shares of Promus Common Stock, par value $0.01 per share, as
described in the above-referenced Registration Statement on Form S-4 (the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Act"). In connection therewith, we have examined, among other things, the
Registration Statement, as well as the proceedings and other actions taken by
the Company in connection with the authorization of the Shares and such other
matters as we deemed necessary for purposes of rendering this opinion.

     Based on the foregoing, and in reliance thereon, we are of the opinion
that (i) the Shares have been duly authorized and (ii) upon issuance of the
Shares in connection with the Acquisition as described in the Registration
Statement and the Prospectus constituting a part thereof ("Prospectus"), the
Shares will be validly issued, fully paid and non-assessable.

     The Company is a Delaware corporation. We are not admitted to practice
in Delaware.  However, we are familiar with the Delaware General Corporation
Law and have made such

review thereof as we consider necessary for the purpose of this opinion.
Subject to the foregoing, this opinion is limited to the present laws of the
State of Delaware and to the present federal laws of the United States of
America.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"Legal Matters" contained in the Prospectus. In giving this consent, we do
not admit that we are within the category of persons whose consent is required
under Section 7 of the Act or the General Rules and Regulations of the
Securities and Exchange Commission.

     Re:   TAX OPINION FOR REGISTRATION STATEMENT ON FORM S-4 (FILE NO._______)

   Ladies and Gentlemen:

       We represent Hilton Hotels Corporation, a Delaware corporation
   ("Hilton"), in connection with the acquisition (the "Acquisition") of
   Promus Hotel Corporation, a Delaware corporation ("Promus"), pursuant to
   an Agreement and Plan of Merger dated as of September 3, 1999, ("Merger
   Agreement") among Hilton, Chicago Hilton, Inc., a Delaware corporation and
   a wholly-owned subsidiary of Hilton ("Merger Subsidiary") and Promus.

       The Merger Agreement provides that the Acquisition will be effectuated
   by a merger of Promus into Merger Subsidiary with Merger Subsidiary being
   the surviving corporation.  However, the Merger Agreement also provides
   that if the value of Hilton stock delivered in the Acquisition is less
   than 40% of the total consideration paid in connection with the
   Acquisition or if legal opinions as to the tax-free nature of the
   acquisition cannot otherwise be delivered, the Acquisition will be
   effectuated by a merger of Merger Subsidiary into Promus with Promus being
   the surviving corporation.  The Merger Agreement is attached as Appendix
   A to Registration Statement on Form S-4, File No. _______ (the
   "Registration Statement"), filed with the Securities and Exchange
   Commission in connection with the Acquisition.

       You have requested our opinion regarding certain United States federal
   income tax consequences of the Acquisition.  In delivering this opinion,
   we have reviewed and relied upon and assumed as accurate (without any
   independent investigation) the facts, statements, descriptions and
   representations set forth in the Registration Statement and such other
   documents pertaining to the Acquisition as we have deemed necessary or
   appropriate.  In connection with rendering this opinion, we have also
   assumed (without any independent investigation):

       1.     The truth and accuracy of the statements, covenants,
   representations and  warranties contained in the Merger Agreement, in the
   representations received from Hilton, Promus and Merger Subsidiary (the
   "Tax Representation Letters") and in all other instruments and documents
   related to the formation, organization and operation of Hilton, Promus and
   Merger Subsidiary that we have reviewed in connection with the Acquisition;

       2.     The authenticity of original documents submitted to us, the
   conformity to the originals of documents submitted to us as copies, and
   the due and valid execution and delivery of all such documents where due
   execution and delivery are a prerequisite to the effectiveness thereof; and

      3.      The performance of all covenants contained in the Merger
   Agreement and the Tax Representation Letters without waiver or breach of
   any material provision thereof. On the basis of the foregoing, we are of
   the opinion that:

      On the basis of the foregoing, we are of the opinion that:

      A.      The Acquisition will constitute a "reorganization" within the
   meaning of Section 368(a) of the Code if Promus merges into Merger
   Subsidiary with Merger Subsidiary being the surviving corporation; and

      B.      The discussion in the Proxy Statement/Prospectus under the
   caption "Certain Federal Income Tax Consequences of the Acquisition," to
   the extent it constitutes summaries of legal matters or legal conclusions
   and subject to the limitations and qualifications set forth therein, is
   accurate in all material respects.

      This opinion expresses our views only as to federal income tax laws in
   effect as of the date hereof, including the Internal Revenue Code of 1986,
   as amended, applicable Treasury Regulations, published rulings and
   administrative practices of the Internal Revenue Service (the "Service")
   and court decisions.  This opinion represents our best legal judgment as
   to the matters addressed herein, but is not binding on the Service or the
   courts.  Furthermore, the legal authorities upon which we rely are subject
   to change either prospectively or retroactively.  Any change in such
   authorities might adversely affect the conclusion stated herein.  We
   undertake no responsibility to advise you of any new developments in the
   application or interpretation of the federal income tax laws.  This
   opinion does not address any other federal, state, local or foreign tax
   consequences.

      No opinion is expressed herein as to any transaction other than the
   Acquisition as described in the Merger Agreement (including any
   transaction undertaken in connection with the Acquisition) or to any
   transaction whatsoever, including the Acquisition, if any of the
   transactions described in the Merger Agreement are not consummated in
   accordance with the

<PAGE>

   Page 3

   terms of such Merger Agreement or if there is a waiver
   or breach of any material provision thereof, or if any of the
   representations, warranties, statements and assumptions upon which we
   relied are not true and accurate at all relevant times.  In the event any
   one of the statements, representations, warranties or assumptions upon
   which we have relied to issue this opinion is incorrect, our opinion might
   be adversely affected and may not be relied upon.

       We hereby consent to the filing of this opinion as an exhibit to the
   Registration Statement and further consent to the use of our name under
   the caption "Certain Federal Income Tax Consequences of the Acquisition"
   in the Proxy Statement/Prospectus included in the Registration Statement.

              INSTRUCTIONS FOR COMPLETION OF LETTER OF TRANSMITTAL

    This Letter of Transmittal should be properly filled in, dated, signed and
delivered, together with the certificate(s) representing the shares of Promus
Common Stock currently held by you, to the Exchange Agent. Please read and
carefully follow the instructions regarding completion of this Letter of
Transmittal set forth below.

INSTRUCTIONS

    1.  EXECUTION AND DELIVERY

    This Letter of Transmittal, or a photocopy of it, should be properly
completed, dated and signed, and should be delivered, together with the
certificate(s) representing your Promus Common Stock, to the Exchange Agent at
the appropriate address set forth on the cover page of this Letter of
Transmittal before the Delivery Deadline.

    THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, AND THE CERTIFICATE(S)
FOR SHARES OF PROMUS COMMON STOCK IS AT THE OPTION AND RISK OF THE STOCKHOLDER.
IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. EXCEPT AS OTHERWISE PROVIDED, DELIVERY WILL BE DEEMED
MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT.

    2.  SIGNATURES

    The signature (or signatures, in the case of certificate(s) owned by two or
more joint holders) on this Letter of Transmittal must correspond exactly to the
name(s) on the face of the certificate(s) sent to the Exchange Agent, unless the
shares of Promus Common Stock represented by the certificate(s) have been
transferred by the holder(s) of record. If there has been any such transfer, the
signature(s) on the Letter of Transmittal should be signed in exactly the same
form as the name of the last transferee indicated on the accompanying stock
powers attached to or endorsed on the certificate(s) (see Instruction 4 below).

    If shares of Promus Common Stock are registered in different names on
several certificates, it will be necessary to complete, sign and submit a
separate Letter of Transmittal for each different registration of certificates.
For example, if some certificates are registered solely in your name, some are
registered solely in your spouse's name and some are registered jointly in the
name of you and your spouse, three separate Letters of Transmittal should be
submitted.

    3.  CHECKS AND/OR CERTIFICATES IN SAME NAME

    If checks in payment of any cash and/or any new certificates for shares of
Hilton Common Stock are to be payable to the order of and/or registered in
exactly the same name on the surrendered certificate(s), you will not be
required to endorse the surrendered certificate(s) or have your signature
guaranteed. For corrections in name or changes in name not involving changes in
ownership, see Instruction 4(c) below.

    4.  CHECKS AND/OR CERTIFICATES IN DIFFERENT NAMES

    If checks in payment of any cash and/or any new certificates for shares of
Hilton Common Stock are to be payable to the order and/or registered in a
different name from the name on the surrendered certificate(s), or delivered to
a different address, please follow these instructions:

           (a)  REGISTERED HOLDERS.  If the registered holder of certificate(s)
       signs the Letter of Transmittal, the registered holder should complete
       Box B and/or Box C and have signature(s) guaranteed on this Letter of
       Transmittal. No endorsements or signature guarantees on certificate(s) or
       stock powers are required in this case.

           (b)  TRANSFEREES.  If the Letter of Transmittal is signed by a person
       other than the registered holder, the certificate(s) surrendered must be
       properly endorsed or accompanied by appropriate stock power(s) properly
       executed by the record holder of such certificate(s) to the person who is
       to receive the check or certificate representing Hilton Common Stock. The
       signature of the record holder on the endorsement(s) or stock power(s)
       must correspond with the name that appears on the face of the
       certificate(s) in every particular and must be guaranteed by a bank,
       broker, dealer, credit union, savings association or other entity that is
       a member in good standing of the Security Transfer Agents Medallion
       Program, the New York Stock Exchange Medallion Signature Guarantee
       Program or the Stock Exchange Medallion Program (each of the foregoing an
       "Eligible Institution"). If this Instruction 4(b) applies, please check
       with your financial

                                       6
<PAGE>
       institution or brokerage firm immediately to determine whether it is an
       Eligible Institution or will need to help you locate an Eligible
       Institution.

           (c)  CORRECTION OF OR CHANGE IN NAME.  For a correction in name which
       does not involve a change in ownership, the surrendered certificate(s)
       should be appropriately endorsed: for example, "John A. Doe, incorrectly
       inscribed as John B. Doe," with the signature guaranteed by an Eligible
       Institution. For a change in name by marriage, etc., the surrendered
       certificate(s) should be appropriately endorsed: for example, "Mary Doe,
       now by marriage Mary Jones," with the signature guaranteed by an Eligible
       Institution.

    5.  SUPPORTING EVIDENCE

    If any Letter of Transmittal, certificate, endorsement or stock power is
executed by an agent, attorney, administrator, executor, guardian, trustee or
any person in any other fiduciary or representative capacity, or by an officer
of a corporation on behalf of the corporation, there must be submitted (with the
Letter of Transmittal, surrendered certificate(s) and/or stock powers)
documentary evidence of appointment and authority to act in such capacity
(including court orders when necessary), as well as evidence of the authority of
the person making such execution to assign, sell or transfer the certificate(s).
Such documentary evidence of authority must be in a form satisfactory to the
Exchange Agent.

    6.  NOTICE OF DEFECTS; RESOLUTION OF DISPUTES

    NEITHER HILTON NOR THE EXCHANGE AGENT WILL BE UNDER ANY OBLIGATION TO NOTIFY
YOU THAT THE EXCHANGE AGENT HAS NOT RECEIVED A PROPERLY COMPLETED LETTER OF
TRANSMITTAL OR THAT THE LETTER OF TRANSMITTAL SUBMITTED IS DEFECTIVE IN ANY WAY.

    Any and all disputes with respect to Letters of Transmittal (including, but
not limited to, matters relating to time limits and defects or irregularities in
the surrender of any certificate) will be resolved by the Exchange Agent and its
decision will be final and binding on all parties concerned. The Exchange Agent
will have the absolute right, in its sole discretion, to reject any and all
Letters of Transmittal and surrenders of certificates which are deemed by it to
be not in proper form or to waive any immaterial irregularities in any Letter of
Transmittal or in the surrender of any certificate. Surrenders of certificates
will not be deemed to have been made until all defects or irregularities that
have not been waived have been cured.

    7.  FEDERAL TAX WITHHOLDING/SUBSTITUTE FORM W-9

    Federal income tax law requires each stockholder to provide the Exchange
Agent with his/her current Taxpayer Identification Number ("TIN") on a
Substitute Form W-9 set forth below. If such stockholder is an individual, the
TIN is his/her social security number. If the Exchange Agent is not provided
with the correct TIN, the stockholder or other payee may be subject to a $50
penalty imposed by the Internal Revenue Service (the "IRS"). In addition,
reportable payments that are made to such stockholder or other payee who has not
provided a correct TIN may be subject to 31% backup withholding.

    Certain persons (including, among others, tax-exempt organizations and
certain foreign persons) are not subject to these backup withholding
requirements. In order for a foreign person to qualify as an exempt recipient,
that person must submit to the Exchange Agent a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that person's exempt status. A
Form W-8 can be obtained from the Exchange Agent. See the enclosed "Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.

    If backup withholding applies, the Exchange Agent is required to withhold
31% of any reportable payment made to the payee. Backup withholding is not an
additional tax. Rather, any amount of tax withheld will be credited against the
tax liability of the person subject to the withholding. If withholding results
in an overpayment of taxes, a refund may be obtained from the IRS.

    If you have not been issued a TIN, but have applied for a TIN or intend to
apply for a TIN in the near future, write "Applied For" in the space for the TIN
in Part I of the Substitute Form W-9 and also complete the Certificate of
Awaiting Taxpayer Identification Number. If the Exchange Agent is not provided
with a TIN by the time of payment, 31% of all reportable payments made to you
will be withheld.

    You are required to give the Exchange Agent the TIN (i.e., social security
number or employer identification number) of the record owner of the Promus
shares. If the shares are registered in more than one name or are not

                                       7
<PAGE>
registered in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

    8.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS

    Any checks representing cash consideration and any certificates representing
Hilton Common Stock will be mailed to the address of the holder of record as
indicated in Box A, or to the person identified in Box B (if completed), unless
instructions to the contrary are given in Box C.

    9.  LOST STOCK CERTIFICATES

    If you are unable to locate the certificates representing your shares of
Promus Common Stock, contact the Exchange Agent at the address provided in the
Letter of Transmittal. The Exchange Agent will instruct you on the procedures to
follow.

    10. MISCELLANEOUS.

    As soon as practicable, the Exchange Agent will begin mailing and delivering
checks and share certificates for Hilton Common Stock in exchange for
certificates that have been received by the Exchange Agent. There will be a
delay, however, if backup withholding pursuant to Instruction 7 applies.

    Requests for assistance may be directed to the Information Agent(s) and
additional copies of the Proxy Statement/Prospectus or this Letter of
Transmittal may be obtained from the Information Agent(s) at the address set
forth below.

 CERTIFICATION--Under penalties of perjury, I certify that:

 (1) The number shown on this form is my correct TIN (or I am waiting for a number to be issued to me); and

 (2) I am not subject to backup withholding because
    (a) I am exempt from backup withholding, or
    (b) I have not been notified by the Internal Revenue Service ("IRS") that I am subject to backup    withholding as a
 result of a failure to report interest or dividends, or
    (c) the IRS has notified me that I am no longer subject to backup withholding.

 CERTIFICATION INSTRUCTIONS--You must cross out item (2) above if you have been notified by the IRS that you are subject
 to backup withholding because of underreporting interest or dividends on your tax return. However, if after being
 notified by the IRS that you were subject to backup withholding, you received another notification from the IRS that you
 were no longer subject to backup withholding, do not cross out item (2). (Also see instructions in the enclosed
 Guidelines.)
