To Our Stockholders:
 
  You are cordially invited to attend a Special Meeting of Stockholders of
Hilton Hotels Corporation, a Delaware corporation ("Hilton"), at the Beverly
Hilton, 9876 Wilshire Boulevard, Beverly Hills, California 90210 on
September 19, 1996, at 11:00 a.m., local time (the "Hilton Special Meeting").
 
  At the Hilton Special Meeting, you will be asked to consider and vote upon a
proposal to approve and adopt the Agreement and Plan of Merger (the "Merger
Agreement") dated as of June 6, 1996, as amended, by and between Hilton and
Bally Entertainment Corporation, a Delaware corporation ("Bally"), pursuant to
which, among other things, Bally will merge with and into Hilton (the
"Merger"), with Hilton being the surviving corporation in the Merger, and to
approve, as required by the rules of the New York Stock Exchange, the grant of
options to purchase shares of common stock of Hilton to the Chairman,
President and Chief Executive Officer of Bally who will become a consultant of
Hilton after the Merger (the "Option Grant," and together with the Merger
Agreement, the "Hilton Merger Proposal"). Upon consummation of the Merger: (i)
each share of common stock of Bally outstanding immediately prior to the
effective time of the Merger will be converted into the right to receive one
share of common stock of Hilton (the "Hilton Common Stock"), after giving
effect to the Stock Split (as hereinafter defined), plus, under certain
circumstances described in the accompanying Joint Proxy Statement/Prospectus,
an additional cash payment, and (ii) each share of the Preferred Redeemable
Increased Dividend Equity Securities, 8% PRIDES, Convertible Preferred Stock
of Bally (the "Bally PRIDES") outstanding immediately prior to the effective
time of the Merger will be converted into the right to receive one share of
Preferred Redeemable Increased Dividend Equity Securities, 8% PRIDES,
Convertible Preferred Stock of Hilton (the "Hilton PRIDES") having rights and
preferences substantially identical to the Bally PRIDES. At the Hilton Special
Meeting, you will also be asked to (i) consider a proposal to amend Hilton's
Certificate of Incorporation, as amended and restated (the "Certificate of
Incorporation") to increase the number of authorized shares of Hilton Common
Stock from 90,000,000 shares to 400,000,000 shares, increase the number of
authorized shares of preferred stock of Hilton (the "Hilton Preferred Stock")
from 10,000,000 shares to 24,832,700 shares and designate 14,832,700 shares of
the Hilton Preferred Stock as Hilton PRIDES; (ii) consider a proposal to
effect a split of Hilton Common Stock, whereby each share of Hilton Common
Stock would be subdivided into four shares of Hilton Common Stock (the "Stock
Split"); and (iii) approve the issuance pursuant to the Merger Agreement of
shares of Hilton Common Stock (estimated to be up to approximately 62,273,733
shares, see "The Merger Agreement--Conversion of Shares"), and up to
14,832,700 shares of Hilton PRIDES.
 
  For the reasons set forth in the accompanying Joint Proxy
Statement/Prospectus, your Board of Directors believes that the Merger is fair
to, and in the best interests of, the stockholders of Hilton and, accordingly,
recommends that you vote in favor of approval and adoption of the Hilton
Merger Proposal and the other proposals described above to be considered at
the Hilton Special Meeting. In making that determination, the Board of
Directors received and took into account the opinion dated June 6, 1996 of
Donaldson, Lufkin & Jenrette Securities Corporation (the "DLJ Opinion") to the
effect that, as of such date, the consideration to be paid by Hilton to the
holders of Bally Common Stock pursuant to the Merger Agreement was fair to
Hilton from a financial point of view. A copy of the DLJ Opinion is included
in the accompanying Joint Proxy Statement/Prospectus as Appendix B thereto.
All of the directors of Hilton, who, as of July 31, 1996, in the aggregate
beneficially owned approximately 26.11% of the outstanding shares of Hilton
Common Stock, have indicated that they intend to vote in favor of approval and
adoption of the Hilton Merger Proposal and the other proposals discussed
above.

"Merger"), with Hilton being the surviving corporation in the Merger. Upon
consummation of the Merger: (i) each share of common stock of Bally (the
"Bally Common Stock") outstanding immediately prior to the effective time of
the Merger will be converted into the right to receive one share of common

and (ii) each share of the Preferred Redeemable Increased Dividend Equity

consummation of the Merger, Hilton will effect a stock split of the Hilton

into four shares of Hilton Common Stock (the "Stock Split"). Holders of Bally
Common Stock will have the right under certain circumstances to dissent from

                                ---------------
 
                           HILTON HOTELS CORPORATION
 
                                  PROSPECTUS
                            SHARES OF COMMON STOCK
               SHARES OF PREFERRED REDEEMABLE INCREASED DIVIDEND
                         EQUITY SECURITIES, 8% PRIDES,
                          CONVERTIBLE PREFERRED STOCK
 
                                ---------------
 
  This Joint Proxy Statement/Prospectus relates to the proposed merger of
Bally Entertainment Corporation, a Delaware corporation ("Bally"), with and
into Hilton Hotels Corporation, a Delaware corporation ("Hilton"), pursuant to
an Agreement and Plan of Merger dated as of June 6, 1996, as amended, between
Hilton and Bally (the "Merger Agreement"). The merger contemplated by the
Merger Agreement is referred to herein as the "Merger."
 
  As a result of the Merger: (i) each share of common stock, par value $.66
2/3 per share, of Bally (the "Bally Common Stock") outstanding immediately
prior to the effective time of the Merger will be converted into the right to
receive one (the "Conversion Number") share of common stock, par value $2.50
per share, of Hilton (the "Hilton Common Stock"), after giving effect to the
Stock Split (as hereinafter defined), plus, under certain circumstances
described below, the Additional Cash Payment (as defined below); and (ii) each
share of the Preferred Redeemable Increased Dividend Equity Securities, 8%
PRIDES, Convertible Preferred Stock of Bally (the "Bally PRIDES") outstanding
immediately prior to the effective time of the Merger shall be converted into
the right to receive one share of Preferred Redeemable Increased Dividend
Equity Securities, 8% PRIDES, Convertible Preferred Stock of Hilton (the
"Hilton PRIDES") having rights and preferences substantially identical to the
Bally PRIDES. In the event that the Determination Price (as defined below) is
less than $27, each holder of shares of Bally Common Stock shall also receive
for each share of Bally Common Stock held by such holder a cash payment (the
"Additional Cash Payment"), not to exceed $3, equal to the excess of $27 over
the Determination Price. The term "Determination Price" means the average of
the daily high and low sales prices of the Hilton Common Stock (regular way),
determined after giving effect to the Stock Split, as shown on the New York
Stock Exchange ("NYSE") Composite Tape (as reported by The Wall Street Journal
or, if not reported thereby, any other authoritative source) for the ten (10)
consecutive days on which the NYSE is open for the transaction of business (a
"Trading Day") ending on the third Trading Day prior to the date upon which
the Merger is consummated (the "Closing Date"). If the Determination Price is
equal to or less than $24, then each holder of shares of Bally Common Stock
will be entitled to receive an Additional Cash Payment of $3 per share of
Bally Common Stock. In the event that the Determination Price is less than
$20, Bally will have the right to terminate the Merger Agreement unless Hilton
shall have notified Bally that it has increased the Conversion Number such
that the product of the Conversion Number and the Determination Price equals
$20. Bally stockholders will still be entitled to receive the Additional Cash
Payment of $3 per share of Bally Common Stock in the event Hilton increases
the Conversion Number.
 
  This Joint Proxy Statement/Prospectus is being furnished to holders of
Hilton Common Stock, the holders of Bally Common Stock and the holders of
Bally PRIDES in connection with the solicitation of proxies by the respective
Boards of Directors of Hilton and Bally for use at a special meeting of
stockholders of Hilton to be held on September 19, 1996 and at a special
meeting of stockholders of Bally to be held on September 18, 1996. This Joint
Proxy Statement/Prospectus and the accompanying forms of proxy are first being
mailed to stockholders of Hilton and Bally on or about August 20, 1996.
 
  At the Bally Special Meeting, holders of Bally Common Stock and Bally PRIDES
will be asked to consider a proposal to approve and adopt the Merger
Agreement. At the Hilton Special Meeting, holders of Hilton Common Stock will
be asked to consider proposals to (i) approve and adopt the Merger Agreement,
and to approve, as required by the rules of the NYSE, the grant of options to
purchase shares of Hilton Common Stock to the Chairman, President and Chief
Executive Officer of Bally who will become a consultant of Hilton after the
Merger; (ii) amend Hilton's Certificate of Incorporation to increase the
number of authorized shares of Hilton Common Stock from 90,000,000 shares to

                                Financial Advisors to Bally" and Appendix D.
 
REGULATORY APPROVALS..........  Consummation of the Merger is subject to
                                certain regulatory approvals, including the
                                expiration or termination of the applicable
                                waiting period under the Hart-Scott-Rodino

                                1996. In addition, the gaming operations of

                                holders of Bally Common Stock are not entitled
                                to dissenters' appraisal rights under the

CERTAIN FEDERAL INCOME TAX
 CONSEQUENCES.................
                                The Merger is intended to qualify as a
                                reorganization within the meaning of Section
                                368(a) of the Internal Revenue Code of 1986, as
                                amended (the "Code"). The obligation of each of
                                Hilton and Bally to consummate the Merger is
                                subject to the condition that it shall have
                                received an opinion of its counsel, dated the
                                closing date of the Merger, to the effect that
                                the Merger will be treated for tax purposes as
                                a reorganization within the meaning of Section
                                368(a) of the Code. Assuming the Merger is so
                                treated, for Federal income tax purposes, the
                                Merger will not result in the recognition of
                                gain or loss to Hilton, Bally, or the holders
                                of Bally Common Stock or Bally PRIDES except
                                (i) with respect to cash received by such
                                holders in lieu of fractional shares and
                                (ii) if a holder of Bally Common Stock receives
                                the Additional Cash Payment, gain, if any,
                                realized by such holder pursuant to the Merger
                                will be recognized, but not in excess of the
                                Additional Cash Payment received. See "The
                                Merger--Certain Federal Income Tax
                                Consequences."
INTERESTS OF CERTAIN PERSONS
 IN THE MERGER................
                                In considering the Merger, stockholders should
                                be aware that Bally's directors and members of
                                Bally's management have certain interests in
                                the Merger. Ten executive officers of Bally
                                currently have employment agreements providing
                                for lump sum severance payments and certain
                                other benefits in the event of a termination of
                                employment following a "Change in Control"
                                (which will occur as of the Effective Time (as
                                hereafter defined)). Arthur M. Goldberg, the
                                Chairman, President and Chief Executive Officer
                                of Bally, will terminate his employment at the
                                Effective Time and as a result he will receive
                                payments under his employment agreement due to
                                the Merger of approximately $15,821,000. The
                                employment agreement of Lee S. Hillman,
                                Executive Vice President, Chief Financial
                                Officer and Treasurer, provides for a lump sum
                                payment of $1,833,334 if Hilton terminates his
                                employment after the Effective Time and
                                $200,000 if Mr. Hillman terminates his
                                employment agreement after the Effective Time.
                                Three other executive officers have employment
                                agreements which provide for a lump sum payment
                                equal to six months base salary upon the
                                voluntary termination of employment following
                                the Change in Control. Such payment increases
                                in the event the termination is by Hilton. The
                                other five executive officers will receive
                                termination payments if Hilton terminates their
                                employment agreements following the Change in
                                Control. All of the executive officers will be
                                reimbursed for excise tax liability resulting
                                from payments made as a result of the Merger.
                                As of July 31, 1996, the executive officers and

                                directors of Bally, as a group, beneficially
                                owned an aggregate of 988,999 shares of Bally
                                Common Stock (excluding shares subject to
                                outstanding stock options) and an aggregate of
                                10,000 shares of Bally PRIDES, which will be
                                treated in the same manner as shares of Bally
                                Common Stock and Bally PRIDES held by other
                                stockholders. As of July 31, 1996, such
                                executive officers and directors, as a group,
                                also held options with respect to 3,706,832
                                shares of Bally Common Stock under Bally's
                                stock option plans (500,000 of the options
                                include tandem stock appreciation rights).
                                Under the Merger Agreement, such options/stock
                                appreciation rights will become immediately
                                exercisable in full at the Effective Time and
                                will be settled in exchange for an amount of
                                cash per option share as set forth below under
                                "The Merger Agreement--Treatment of Stock
                                Options." In addition, pursuant to the Merger
                                Agreement, Bally's Casino, Inc., a subsidiary
                                of Bally ("Bally Casino"), will be merged with
                                and into Bally immediately prior to the Merger,
                                with Bally continuing as the surviving
                                corporation, and as a result, all shares of
                                Bally Casino's Series A Cumulative Exchangeable
                                Preferred Stock currently held by Mr. Goldberg
                                will be converted into Bally Common Stock which
                                in turn will be converted into shares of Hilton
                                Common Stock in the Merger. The Board of
                                Directors of Bally has approved certain
                                transactions between Bally and Mr. Goldberg
                                that will occur immediately prior to the
                                Effective Time, subject to the consummation of
                                the Merger, and upon consummation of the
                                Merger, these arrangements will be binding on
                                Hilton. See "The Merger--Interests of Certain
                                Persons in the Merger."
 
                              THE MERGER AGREEMENT
 
TERMS OF THE MERGER...........  The Merger Agreement provides that, following
                                the approval and adoption of the Merger
                                Agreement by the stockholders of Hilton and
                                Bally and the satisfaction or waiver of the
                                other conditions to the Merger, Bally will be
                                merged with and into Hilton, and Hilton shall
                                continue as the surviving corporation. As a
                                result of the Merger, Bally shall cease to
                                exist and Hilton shall succeed to and assume
                                all rights and obligations of Bally in
                                accordance with the DGCL.
 
EFFECTIVE TIME OF THE           The Merger will become effective upon the
 MERGER.......................  filing of a Certificate of Merger with the
                                Secretary of State of the State of Delaware
                                (the "Effective Time") upon the satisfaction or
                                waiver of the conditions to the Merger.
 
CONVERSION OF SHARES .........  At the Effective Time: (i) each issued and
                                outstanding share of Bally Common Stock will be
                                converted into the right to receive one share
                                of Hilton Common Stock, after giving effect to
                                the Stock Split, provided that if the
                                Determination Price is less than $27, each
                                holder of Bally Common Stock will receive an
 
                                       7
<PAGE>
 
                                additional cash payment for each share equal to
                                the difference between $27 and the
                                Determination Price, up to a maximum of $3 per
                                share; and (ii) each issued and outstanding
                                share of Bally PRIDES will be converted into
                                the right to receive one share of Hilton
                                PRIDES.
 
                                In the event that the Determination Price is
                                less than $20, Hilton shall have the right, but
                                not the obligation, to give written notice to
                                Bally (the "Top-Up Intent Notice") that the
                                Board of Directors of Hilton has elected to
                                increase the Conversion Number such that the
                                product of the Conversion Number and the
                                Determination Price equals $20. Such increase,
                                however, will not result in any increase or
                                decrease in the amount of the Additional Cash
                                Payment which will, in such circumstances,
                                equal $3 per share.
 
TREATMENT OF STOCK OPTIONS....  At the Effective Time, each then outstanding
                                option to purchase shares of Bally Common Stock

                                right to receive cash in an amount equal to all
                                accrued and unpaid dividends thereon (other
                                than previously declared dividends payable to a
                                holder of record as of a prior date). If an
                                Additional Cash Payment is made in connection
                                with the Merger, at conversion a holder of
                                Hilton PRIDES will receive a cash payment in an
                                amount equal to the Additional Cash Payment
                                such holder would have received if such
                                conversion had occurred immediately prior to
                                the Effective Time. The value of the shares of
                                Hilton Common Stock that may be received by
                                holders of shares of Hilton PRIDES upon their
                                mandatory conversion may be more or less than
                                the value of the Bally PRIDES being surrendered
                                in exchange for shares of Hilton PRIDES in the
                                Merger due to market fluctuations in the price
                                of the Hilton Common Stock.
 
OPTIONAL REDEMPTION...........  Shares of Hilton PRIDES are not redeemable

                                Redemption Date"). At any time and from time to
                                time on or after the Initial Redemption Date,
                                and ending immediately prior to the Mandatory
                                Conversion Date, Hilton may redeem any or all
                                of the outstanding shares of Hilton PRIDES.
                                Upon any such redemption, each holder will
                                receive, in exchange for each share of Hilton
                                PRIDES, the number of shares of Hilton Common
                                Stock equal to (A) the sum of (i) $11.348,
                                declining after January 3, 1998, to $11.125 at
                                the Mandatory Conversion Date; and (ii) all
                                accrued and unpaid dividends thereon (other
                                than previously declared dividends payable to a
                                holder of record as of a prior date) (the "Call
                                Price"); divided by (B) the Current Market
                                Price (as defined herein) on the applicable
                                date of determination, but in no event less
                                than 0.92 of one share of Hilton Common Stock
                                (after giving effect to the Stock Split),

                                subject to adjustment in certain events. If an
                                Additional Cash Payment is made in connection
                                with the Merger, at redemption a holder of
                                Hilton PRIDES will receive a cash payment in an
                                amount equal to the Additional Cash Payment
                                such holder would have received if such
                                redemption had occurred immediately prior to
                                the Effective Time. The number of shares of
                                Hilton Common Stock to be delivered in payment
                                of the applicable Call Price will be determined
                                on the basis of the Current Market Price of the
                                Hilton Common Stock prior to the announcement
                                of the redemption, and the market price of the
                                Hilton Common Stock may vary between the date
                                of such determination and the subsequent
                                delivery of such shares.
 
CONVERSION AT THE OPTION OF     At any time prior to the Mandatory Conversion
 THE HOLDER...................  Date, unless previously redeemed, each share of
                                Hilton PRIDES will be convertible at the option
                                of the holder thereof into 0.92 of a share of
                                Hilton Common Stock (after giving effect to the
                                Stock Split), subject to adjustment in certain
                                events (the "Optional Conversion Rate"),
                                equivalent to a conversion price of $12.092 per
                                share (after giving effect to the Stock Split)
                                of Hilton Common Stock (the "Conversion
                                Price"), subject to adjustment in certain
                                events. If an Additional Cash Payment is made
                                in connection with the Merger, at conversion a
                                holder of Hilton PRIDES will receive a cash
                                payment in an amount equal to the Additional
                                Cash Payment such holder would have received if
                                such conversion had occurred immediately prior
                                to the Effective Time. The value of the shares
                                received upon conversion by a holder will vary
                                depending on the market price of the Hilton
                                Common Stock from time to time, and adjustment
                                in certain events, all as set forth herein. The
                                right of holders to convert shares of Hilton
                                PRIDES called for redemption will terminate
                                immediately prior to the close of business on
                                the applicable redemption date.

                                have the right with the holders of Hilton

                                of Hilton PRIDES and the holders of Hilton

 (1) Net income for Hilton in 1993 includes a credit of $3.4 million ($.07 per
     share) resulting from the implementation of new accounting standards for
     income taxes and post-retirement benefits other than pensions.
 (2) Does not give effect to the Stock Split.
 (3) "EBITDA" consists of operating income plus consolidated depreciation,
     amortization and abandonment loss. Hilton and Bally have presented EBITDA
     supplementally because the companies believe it allows for a more complete
     analysis of their results of operations. This information should not be
     considered as an alternative to any measure of performance or liquidity as
     promulgated under generally accepted accounting principles (such as net
     income or cash provided by or used in operating, investing and financing
     activities) nor should it be considered as an indicator of the overall
     financial performance of Hilton and Bally.
 (4) The ratio of earnings to fixed charges is calculated by dividing (i)
     income (loss) from continuing operations before income taxes and minority
     interests plus fixed charges (adjusted for capitalized interest) by (ii)
     fixed charges. Fixed charges consist of interest incurred (expensed or
     capitalized) and the portion of rent expense which is deemed
     representative of interest.
 (5) Bally's Las Vegas has been consolidated since December 1, 1993 as a result
     of Bally's controlling interest in Bally's Grand, Inc. at that date. Prior
     to December 1, 1993, Bally's investment in Bally's Grand, Inc. was
     principally recorded on the equity method of accounting. As of June 30,
     1996, Bally (through a subsidiary of which it is the sole common
     stockholder) owned approximately 85% of the outstanding common stock of
     Bally's Grand, Inc. In addition, Bally's New Orleans commenced operation
     of its riverboat casino in July 1995 and Bally's Mississippi reopened its
     dockside casino in December 1995. Between December 1993 and February 1995,
     Bally's Mississippi operated the dockside casino at a different site.
 (6) Total revenue, total operating income and EBITDA for Bally for the six
     months ended June 30, 1996 and 1995 and the years ended December 31, 1995,
     1994, 1993, 1992 and 1991 exclude interest income of $9.2 million, $5.9
     million, $13.7 million, $9.1 million, $5.9 million, $3.2 million and $7.3
     million, respectively, to conform to the financial presentation of Hilton.
 (7) Income from continuing operations and net income for Bally for the year
     ended December 31, 1995 include a credit of $41.0 million ($.76 per share)
     for certain adjustments to the prior years' income taxes. Loss from
     continuing operations and net loss for the year ended December 31, 1994
     include a charge (net of taxes) of $8.5 million ($.18 per share) to write
     off certain assets which were abandoned upon the relocation of Bally's
     Mississippi's operations closer to Memphis, Tennessee.
 (8) Net income (loss) for Bally includes losses from discontinued operations
     of $11.0 million ($.20 per share), $46.1 million ($.98 per share), $20.0
     million ($.43 per share) and $1.2 million ($.03 per share) for the years
     ended December 31, 1995, 1994, 1993 and 1991, respectively, and net income
     for the year ended December 31, 1992 includes income from discontinued
     operations of $.6 million ($.01 per share). Net income for the six months
     ended June 30, 1995 and the years ended December 31, 1995, 1992 and 1991
     includes extraordinary gains of $.4 million ($.01 per share), $.4 million
     ($.01 per share), $11.2 million ($.27 per share) and $56.1 million
     ($1.65 per share), respectively, and net income (loss) for the six months
     ended June 30, 1996 and the years ended December 31, 1994 and 1993
     includes extraordinary losses of $.6 million ($.01 per share), $20.4
     million ($.44 per share) and $8.5 million ($.18 per share), respectively.
     In addition, net loss for the year ended December 31, 1993 includes a
     charge for the cumulative effect on prior years of change in accounting
     for income taxes of $28.2 million ($.61 per share).
 (9) Bally's earnings were insufficient to cover fixed charges for the years
     ended December 31, 1992 and 1991 by $6.5 million and $50.2 million,
     respectively.
(10) The ratio of earnings to combined fixed charges and preferred stock
     dividends is calculated by dividing (i) income (loss) from continuing
     operations before income taxes and minority interests plus fixed charges
     (adjusted for capitalized interest and preferred stock dividend
     requirements of consolidated subsidiaries) by (ii) fixed charges plus
     total preferred stock dividend requirements.
(11) Bally's earnings were insufficient to cover combined fixed charges and
     preferred stock dividends for the years ended December 31, 1992 and 1991
     by $9.3 million and $53.0 million, respectively.

Special Meeting. The presence, in person or by proxy, of the holders of shares
of Hilton Common Stock entitled to cast a majority of the votes entitled to be
cast at the Hilton Special Meeting will constitute a quorum at the Hilton
Special Meeting.
 
  The Board of Directors of Bally has fixed the close of business on August
16, 1996 (the "Bally Record Date") for the determination of the holders of
Bally Common Stock and Bally PRIDES entitled to receive notice of and to vote
at the Bally Special Meeting. The presence, in person or by proxy, of the
holders of Bally Common Stock and Bally PRIDES entitled to cast a majority of
the votes entitled to be cast at the Bally Special Meeting will constitute a
quorum at the Bally Special Meeting.
 
VOTES REQUIRED
 
  As of August 15, 1996, there were outstanding and entitled to vote
48,854,451 shares of Hilton Common Stock, excluding 2,170,256 shares held in
Hilton's treasury. Each share of Hilton Common Stock is entitled to one (1)
vote on each matter that comes before the Hilton Special Meeting. Approval and
adoption of the Hilton Merger Proposal and the Related Hilton Proposals
requires the affirmative vote of a majority of all outstanding shares of
Hilton Common Stock (other than the Stock Issuance, which, assuming the
presence of a quorum, requires the affirmative vote of a majority of the votes
cast with respect to such proposal).
 
  As of July 31, 1996, directors and executive officers of Hilton and their
affiliates beneficially owned an aggregate of 12,764,315 shares of Hilton
Common Stock, or approximately 26.13% of the shares of Hilton Common Stock
outstanding on such date. The directors and executive officers of Hilton and
their affiliates have indicated their intentions to vote the shares of Hilton
Common Stock beneficially owned by them in favor of approval of the Hilton
Merger Proposal and the Related Hilton Proposals.
 
  At the Bally Special Meeting, the outstanding shares of Bally Common Stock
and Bally PRIDES will vote together as a single class. As of August 15, 1996,
there were outstanding and entitled to vote 51,620,865 shares of Bally Common
Stock and 14,832,700 shares of Bally PRIDES. Each share of Bally Common Stock
is
 
                                      20
<PAGE>

entitled to one vote on each matter that comes before the Bally Special
Meeting, and each share of Bally PRIDES is entitled to four-fifths (4/5ths) of
one vote on each matter that comes before the Bally Special Meeting. Approval
and adoption of the Bally Merger Proposal requires the affirmative vote of a
majority of the votes entitled to be cast by the holders of all issued and
outstanding shares of Bally Common Stock and Bally PRIDES.
 
  As of July 31, 1996, Bally directors and executive officers and their
affiliates beneficially owned an aggregate of 988,999 shares of Bally Common
Stock and 10,000 shares of Bally PRIDES, or approximately 1.9% of Bally Common
Stock and approximately .1% of the Bally PRIDES outstanding on such date. The
directors and executive officers of Bally and their affiliates have indicated
their intention to vote the shares of Bally Common Stock and Bally PRIDES
beneficially owned by them in favor of the approval of the Bally Merger
Proposal.
 
  In the event that the Merger Agreement is not approved and adopted by both
the Hilton and Bally stockholders, the Merger Agreement may be terminated in
accordance with its terms. See "The Merger Agreement--Termination."
 
VOTING AND REVOCATION OF PROXIES
 
  Shares of Hilton Common Stock, Bally Common Stock and Bally PRIDES
represented by a proxy properly signed and received at or prior to the
appropriate Special Meeting, unless subsequently revoked, will be voted in
accordance with the instructions thereon. If a proxy for the Hilton Special
Meeting is properly executed and returned without indicating any voting
instructions, shares of Hilton Common Stock represented by the proxy will be
voted for approval of the Hilton Merger Proposal and the Related Hilton
Proposals. If a proxy for the Bally Special Meeting is properly executed and
returned without indicating any voting instructions, shares of Bally Common
Stock or Bally PRIDES, as applicable, represented by the proxy will be voted
for approval of the Bally Merger Proposal. Any proxy given pursuant to the
solicitation may be revoked by the person giving it at any time before the
proxy is voted by the filing of an instrument revoking it, or of a duly
executed proxy bearing a later date, with the Secretary of Hilton, for Hilton
stockholders, or with the Secretary of Bally, for Bally stockholders, prior to
or at the appropriate Special Meeting, or by voting in person at the
appropriate Special Meeting. Attendance at a Special Meeting will not in and
of itself constitute a revocation of a proxy. Because the approval of the
Hilton Merger Proposal and certain of the Related Hilton Proposals require the
affirmative vote of a majority of the issued and outstanding shares of Hilton
Common Stock, abstentions and broker non-votes with respect to such shares
will be the equivalent of votes against such proposals. Because approval of
the Bally Merger Proposal by the stockholders of Bally requires the
affirmative vote of a majority of all votes entitled to be cast by all holders
of the issued and outstanding shares of Bally Common Stock and Bally PRIDES,
abstentions and broker non-votes with respect to such shares will be
equivalent to votes against approval of the Bally Merger Proposal.
 
  Proxies sent via facsimile transmission will be accepted if received not
later than fifteen (15) minutes prior to the scheduled commencement of the
relevant Special Meeting. Such proxies may be sent via facsimile for Hilton to
D.F. King & Co., Inc., proxy solicitors for Hilton, at (212) 809-8839 and for
Bally, to MacKenzie Partners, Inc., proxy solicitors for Bally, at (212) 929-
0308.
 
  The Boards of Directors of Hilton and Bally are not aware of any business to
be acted upon at the Special Meetings of their respective stockholders other
than as described herein. If, however, other matters are properly brought
before either Special Meeting, or any adjournments or postponements thereof,
the persons appointed as proxies will have discretion to vote or act thereon
according to their best judgment and subject to applicable rules of the SEC or
Delaware law.
 
SOLICITATION OF PROXIES
 
  In addition to solicitation by mail, directors, officers and employees of
Hilton and Bally, who will not be specifically compensated for such services,
may solicit proxies from the stockholders of Hilton and Bally, respectively,
personally or by telephone or telegram or other forms of communication.
Brokerage houses,
 
                                      21

nominees, fiduciaries and other custodians will be requested to forward
soliciting materials to beneficial owners and will be reimbursed for their
reasonable expenses incurred in doing so.
 
  Hilton has retained D.F. King & Co., Inc. to assist in the solicitation of
proxies from its stockholders. The fees to be paid to D.F. King & Co., Inc.
for such services by Hilton are not expected to exceed approximately $8,000
plus reasonable out-of-pocket costs and expenses. Bally has retained MacKenzie
Partners, Inc. to assist in the solicitation of proxies from its stockholders.
The fees paid to MacKenzie Partners, Inc. are not expected to exceed
approximately $15,000, plus reasonable out-of-pocket costs and expenses. Each
of Hilton and Bally will bear its own expenses in connection with the
solicitation of proxies for its Special Meeting, except that Hilton and Bally
each will pay one-half of the expenses incurred in printing this Joint Proxy
Statement/Prospectus, the forms of proxies and other proxy materials.
 
STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY CARDS. THE

AGREEMENT--EXCHANGE PROCEDURES."
 
                                  THE MERGER
 
BACKGROUND TO THE MERGER AND REASONS FOR THE MERGER
 
 General Background--Hilton
 
  In November 1994, Hilton commenced a process of evaluating possible
strategic alternatives to enhance stockholder value and engaged an investment
banking firm to undertake a study and make recommendations to Hilton's
management and Board of Directors concerning such strategic alternatives.
These alternatives included the sale of the entire company in one or a series
of transactions; the spin-off of one or more of Hilton's businesses; a
recapitalization; a share repurchase program; a business combination; or other
acquisitions and similar transactions. As a result of the evaluation of such
alternatives, in June 1995, the Board of Directors of Hilton approved a plan
to separate Hilton's gaming and hotel businesses by means of a spin-off of
Hilton's gaming operations. In the course of pursuing the spin-off, however,
management continued to evaluate other strategic alternatives and, in January
1996, Hilton's Board of Directors determined to continue to develop the
marketing, operating and financial efficiencies between its hotel and gaming
businesses. Accordingly, Hilton announced in January 1996 that it would not
proceed with the spin-off of its gaming operations and determined to pursue
expansion of its gaming operations through acquisitions, the development of
new facilities and enhancement of its existing gaming properties.
 
 General Background--Bally
 
  Over the past few years Bally has faced increased competition from both
established casinos and newly emerging gaming operations, including gaming
facilities operated by Native American Indians. Recent developments such as
the legalization of casino gaming in new geographic markets and the increasing
popularity of riverboat gaming have forced Bally to expend significant
resources to develop a presence in new markets while at the same time
expending capital to upgrade and improve its existing locations. In order to
capitalize on the growth in the new markets, and to counter the increasing
competitive pressures, Bally embarked upon a major capital expenditures and
expansion program to improve and expand its existing properties and to build
additional properties. In order to implement this expansion program, Bally
determined that it would need access to substantial capital. Over the past two
years, Bally has considered various ways to raise capital and position itself
to compete effectively against the growing field of large, well-capitalized
companies in the gaming industry.
 
 Prior Negotiations with Hilton and Other Parties
 
  In mid-February 1996, representatives of a significant industry participant
(the "Industry Participant") contacted Arthur M. Goldberg, the Chairman, Chief
Executive Officer and President of Bally, regarding a
 
                                      22
<PAGE>
 
possible business combination. In order to explore such combination on a
preliminary basis, the parties agreed to exchange certain non-public
information and accordingly executed a confidentiality agreement on February
16, 1996. In March 1996, representatives of Hilton contacted Mr. Goldberg
regarding a possible business combination, and the two companies exchanged
certain non-public information pursuant to a confidentiality agreement which
was executed on March 11, 1996. These preliminary discussions with the
Industry Participant and Hilton did not result in any offer for a transaction
involving Bally. In April 1996, representatives of each of the Industry
Participant and Hilton separately approached Mr. Goldberg to initiate further
discussions about a possible business combination involving Bally. After
preliminary negotiations with the Industry Participant, the Industry
Participant discussed with Bally a stock for stock merger proposal involving
an exchange of stock having a value of $26.00 for each share of Bally Common
Stock based on the trading price of the Industry Participant common stock at
that time. However, this proposal did not include any protection for Bally
stockholders in the event of a decline in the price of the Industry
Participant's common stock. At the same time that Bally was engaging in
negotiations with the Industry Participant, Bally and Hilton held discussions
about a possible merger, including a discussion with Bally of a proposal in
which .2285 shares of Hilton Common Stock would be issued in exchange for each
share of Bally Common Stock, which represented approximately $23.75 for each
share of Bally Common Stock based on the trading price of Hilton Common Stock
at that time. This proposal included limited protection against a decline in
the stock price of Hilton's Common Stock. Bally engaged Goldman Sachs and
Merrill Lynch as financial advisors to assist in analyzing the proposals
discussed with the Industry Participant and Hilton. Discussions with the
Industry Participant terminated when the Industry Participant did not agree to
protect Bally stockholders against a stock price decline and discussions with
Hilton terminated due to an impasse over price. At the regular Bally Board of
Directors meetings held on March 13, 1996 and May 21, 1996, the Bally Board of
Directors reviewed the status of the preliminary merger discussions with the
Industry Participant and Hilton.
 
 Negotiations of the Merger
 
  At the end of May 1996, representatives of Hilton contacted Mr. Goldberg in
order to resume discussions concerning a possible business combination. Hilton
discussed with Bally a stock for stock merger involving an exchange of one
share of Hilton Common Stock for each share of Bally Common Stock (after
giving effect to the Stock Split), plus protection for Bally stockholders
against a decline in the price of Hilton Common Stock below $27 per share
(after giving effect to the Stock Split) in the form of a cash payment of up
to $3 per share. Based on the trading price of Hilton Common Stock at that
time, this represented approximately $27 per share of Bally Common Stock.
While Bally was considering the Hilton proposal, it authorized one of Bally's
financial advisors to approach the Industry Participant to ascertain whether
the Industry Participant was interested in holding merger discussions with
Bally. The Industry Participant declined.
 
  During the week of June 2, 1996, Bally and its financial and legal advisors
met with Hilton and its advisors to negotiate the terms of a proposed merger
agreement and other ancillary agreements. The entire Board of Directors of
Bally met on June 6, 1996 to consider the proposed merger agreement with
Hilton and other ancillary agreements and matters. At this meeting,
representatives of Weil, Gotshal & Manges, legal counsel to Bally, and Goldman
Sachs and Merrill Lynch, financial advisors to Bally, made presentations to
and had discussions with the Bally Board of Directors. The Bally Board of
Directors reviewed and discussed, among other things, (i) the background of
the proposed merger; (ii) financial and valuation analyses of the proposed
merger; (iii) the terms of the proposed merger agreement; (iv) regulatory
aspects of the Merger; (v) certain affiliate transactions described below
under "--Interests of Certain Persons in the Merger"; and (vi) other matters
described below under "--Recommendation of the Bally Board of Directors;
Bally's Reasons for the Merger." Goldman Sachs rendered its oral opinion
(subsequently confirmed in writing as of the date hereof) that, based upon and
subject to the matters set forth therein and based upon such other matters as
it considered relevant, as of such date, the total consideration to be
received by the holders of shares of Bally Common Stock pursuant to the Merger
was fair to such holders. Merrill Lynch rendered its oral opinion
(subsequently confirmed in writing as of the date hereof) that, on the basis
of and subject to the matters set forth therein, as of such date, the
consideration to be received by holders of shares of Bally Common Stock
pursuant to the Merger was fair to
 
                                      23
<PAGE>
 
such holders from a financial point of view. After further deliberation, the
Bally Board of Directors unanimously approved the terms of the Merger
Agreement and the transactions contemplated thereby and authorized the
execution of the Merger Agreement.
 
  Also on June 6, 1996, the Board of Directors of Hilton met to consider the
proposed merger agreement and the other ancillary agreements. At this meeting,
representatives of Latham & Watkins, legal counsel to Hilton, and DLJ,
financial advisor to Hilton, made presentations to the Board of Directors of
Hilton and discussed the terms of the proposed transaction. The Board of
Directors further discussed the terms of the proposed transaction, and DLJ
rendered its written opinion that as of such date, the consideration to be
paid by Hilton pursuant to the Merger Agreement was fair to Hilton from a
financial point of view. After further deliberation, the Board of Directors of
Hilton unanimously approved the terms of the Merger Agreement and the
transactions contemplated thereby.
 
 Recommendation of the Hilton Board of Directors; Hilton's Reasons for the
Merger
 
  THE HILTON BOARD OF DIRECTORS, BY UNANIMOUS VOTE, HAS DETERMINED THAT THE
MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF HILTON
AND RECOMMENDS THAT THE STOCKHOLDERS OF HILTON VOTE FOR THE HILTON MERGER
PROPOSAL AND THE HILTON RELATED PROPOSALS.
 
  The Board of Directors of Hilton has unanimously determined that the Merger
is advisable and fair to, and in the best interests of, the stockholders of
Hilton. In approving the Merger Agreement and the transactions contemplated
thereby, the Board of Directors of Hilton considered a number of factors. The
factors material to the decision of the Board of Directors of Hilton are
summarized below:
 
    (i) The strategic benefits of significantly expanding Hilton's gaming
  operations and the value of Bally's gaming properties.
 
    (ii) The fact that the Merger would provide Hilton with a significant
  presence in the Atlantic City, New Jersey gaming market.
 
    (iii) The fact that, after taking into account savings resulting from
  Hilton's lower cost of capital relative to that of Bally, the Merger is
  expected to be accretive to Hilton's earnings per share by the end of the
  first year of operations following the Merger.
 
    (iv) The opportunity to achieve significant synergies by combining the
  management expertise of the two companies and exploiting the potential
  economies of scale and cost savings in general and administrative expenses.
 
    (v) The financial condition, results of operation and cash flows of
  Hilton and Bally.
 
    (vi) The terms and conditions of the Merger Agreement, including the
  amount and form of the Merger Consideration.
 
    (vii) The historical market prices and trading information with respect
  to the Hilton Common Stock and the Bally Common Stock.
 
    (viii) The presentation of DLJ to the Board of Directors of Hilton,
  including DLJ's written opinion, dated as of June 6, 1996, to the effect
  that, as of the date of such opinion, the consideration to be paid by
  Hilton pursuant to the Merger Agreement was fair to Hilton, from a
  financial point of view. See "--Opinion of Financial Advisor to Hilton."
 
  In view of the number and disparate nature of the factors considered by the
Board of Directors of Hilton, the Hilton Board of Directors did not assign
relative weight to the factors considered in reaching its conclusions. Rather,
the Board of Directors of Hilton viewed its conclusions and recommendations as
being based on the totality of the information being presented to and
considered by it.

 Recommendation of the Bally Board of Directors; Bally's Reasons for the
Merger.
 
  THE BALLY BOARD OF DIRECTORS, BY UNANIMOUS VOTE, HAS DETERMINED THAT THE
MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE STOCKHOLDERS OF BALLY AND
RECOMMENDS THAT THE STOCKHOLDERS OF BALLY VOTE FOR THE BALLY MERGER PROPOSAL.
 
  The Bally Board of Directors believes the Merger offers its stockholders a
unique opportunity to participate in the growth of a company, which, after the
Merger, will be the largest operator of casinos in the United States. The
Bally Board of Directors also believes that as a result of the Merger, Bally's
operations will have better access to the substantial capital it needs for its
expansion program. In addition, the Bally Board of Directors has determined
that the Merger affords Bally stockholders a substantial premium over the
market price of Bally Common Stock, which was trading in the range of $14 1/2
to $17 3/8 per share prior to the first public commentary regarding a possible
business combination pushed the market price to above $23 per share in April
1996. Based on the closing sales price of Hilton Common Stock on the date of
the Merger Agreement, Bally stockholders would receive Hilton Common Stock
having a value of $28.40 for each share of Bally Common Stock, representing a
premium of 8.6% over the closing sales price of Bally Common Stock on June 5,
1996, the date before the execution of the Merger Agreement, and of 102.8%
over the highest closing sales price of Bally Common Stock during 1995.
 
  The decision of the Bally Board of Directors to approve the Merger Agreement
and to recommend approval of the Merger by the stockholders of Bally was based
upon a number of factors, including without limitation, the following:
 
    (i) the Bally Board of Directors' recognition of the increased capital
  amounts required for Bally to maintain its competitive position;
 
    (ii) the Bally Board of Directors' understanding of the present and
  anticipated environment of the gaming industry and the potential for
  further consolidation within the industry that could adversely affect
  Bally's competitive position;
 
    (iii) the Bally Board of Directors' consideration of, among other things,
  information concerning the financial condition, results of operations,
  prospects and businesses of Bally and Hilton;
 
    (iv) the Bally Board of Directors' consideration of, among other things,
  current industry, economic and market conditions;
 
    (v) the Bally Board of Directors' understanding that the Merger should
  aid Bally's expansion of its gaming operations, and specifically that the
  expansion program would benefit from financing alternatives that are not
  currently available to Bally;
 
    (vi) the terms of the Merger Agreement, including without limitation, the
  form of consideration, the proposed price protection (up to a $3 cash
  payment in the event of a decline in the price of Hilton Common Stock below
  $27 per share), the tax-free structure of the Merger, the degree of
  flexibility provided to Bally to conduct its business prior to closing the
  Merger, Bally's right to terminate the Merger Agreement in the event
  Hilton's stock price, as adjusted to reflect the Stock Split, declines
  below $20 per share (the total per share consideration at this level being
  $23 per share as a result of the $3 cash payment) and Hilton does not offer
  to increase the stock consideration, Bally's "no-solicitation" covenant
  which prohibits Bally from soliciting any acquisition proposal or, subject
  to the fiduciary duties of the Bally Board of Directors, from negotiating
  with any other parties with respect to an acquisition proposal, and the
  obligation of Bally to pay a termination fee to Hilton if an acquisition
  proposal were consummated or an agreement were entered into with respect
  thereto in the 12 months following termination of the Merger Agreement;
 
    (vii) the Bally Board of Directors' receipt of opinions from Goldman
  Sachs that, based upon and subject to the matters set forth therein and
  based upon such other matters as it considered relevant, as of the date of
  the Merger Agreement and the date of this Joint Proxy Statement/Prospectus,
  respectively, the total
 
                                      25
<PAGE>
 
  consideration to be received by the holders of Bally Common Stock pursuant
  to the Merger is fair to such holders; and
 
    (viii) the Bally Board of Directors' receipt of opinions from Merrill
  Lynch that, on the basis of and subject to the matters set forth therein,
  as of the date of the Merger Agreement and the date of this Joint Proxy
  Statement/Prospectus, respectively, the consideration to be received by the
  holders of Bally Common Stock pursuant to the Merger is fair to such
  holders from a financial point of view.
 
  The Bally Board of Directors did not assign relative weights to the factors
discussed above.
 
OPINION OF FINANCIAL ADVISOR TO HILTON
 
  Hilton selected DLJ as its exclusive financial advisor with respect to the
Merger because DLJ is a nationally recognized investment banking firm that has
substantial experience in the gaming and lodging industries and is familiar
with Hilton, Bally and their respective businesses. As part of its investment
banking business, DLJ 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 estate, corporate and other purposes.
 
  As part of its role as financial advisor to Hilton, DLJ was asked to render
an opinion to the Board of Directors of Hilton as to the fairness to Hilton of
the consideration to be paid by Hilton to holders of Bally Common Stock
pursuant to the Merger Agreement. On each of June 6, 1996 and August 15, 1996,
DLJ delivered to the Board of Directors of Hilton its written opinion
(collectively, the "DLJ Opinion") that, based upon and subject to the
provisions set forth in such opinions, the consideration to be paid by Hilton
to the holders of Bally Common Stock pursuant to the Merger Agreement is fair
to Hilton from a financial point of view.
 
  A COPY OF THE DLJ OPINION IS ATTACHED HERETO AS APPENDIX B. HOLDERS OF
HILTON COMMON STOCK ARE URGED TO READ THE DLJ OPINION IN ITS ENTIRETY FOR THE
ASSUMPTIONS MADE, THE MATTERS CONSIDERED AND THE LIMITS OF THE REVIEW MADE BY
DLJ IN CONNECTION WITH SUCH OPINION.
 
   The DLJ Opinion was prepared for the Hilton Board of Directors and is
directed only to the fairness to Hilton from a financial point of view of the
consideration to be paid by Hilton to holders of Bally Common Stock. The DLJ
Opinion does not constitute a recommendation to any holder as to how to vote
on the Merger. DLJ did not make any recommendation as to the form or amount of
consideration to be paid by Hilton pursuant to the transactions contemplated
by the Merger Agreement. Such consideration was determined by arm's length
negotiations between Hilton and Bally in which negotiations DLJ advised Hilton
management. DLJ's opinion does not constitute an opinion as to the prices at
which the Hilton Common Stock will actually trade at any time, including the
Effective Time. No restrictions or limitations were imposed by Hilton upon DLJ
with respect to the investigations made or the procedures followed by DLJ in
rendering the DLJ Opinion.
 
  In arriving at its opinion, DLJ reviewed the Merger Agreement. DLJ also
reviewed financial and other information that was publicly available or
furnished to it by Hilton and Bally, including information provided during
discussions with their respective managements. Included in the information
provided to DLJ were certain financial projections of Hilton and Bally
prepared by management of Hilton and Bally, respectively. In addition, DLJ
compared certain financial and securities data of Hilton and Bally with
various other companies whose securities are traded in the public markets,
reviewed historical stock prices and trading volumes of Hilton Common Stock
and Bally Common Stock, reviewed prices and financial data implied by the
consideration paid in other business combinations and conducted such other
financial studies, analyses and investigations as DLJ deemed appropriate for
the purposes of its opinion.
 
  In rendering the DLJ Opinion, DLJ, with the consent of the Board of
Directors of Hilton, relied upon and assumed the accuracy, completeness and
fairness of all of the financial and other information that was available to
it from public sources, that was provided to it by Hilton and Bally or their
respective representatives or that
 
                                      26
<PAGE>
 
was otherwise reviewed by DLJ. DLJ also, with the consent of the Board of
Directors of Hilton, assumed that the financial projections supplied to it
were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the managements of Hilton and Bally as to the
future operating and financial performance of Hilton and Bally, respectively,
and of the operating synergies and other cost reductions achievable as a
result of the Merger. DLJ has not assumed any responsibility for making any
independent evaluation or appraisal of the assets or liabilities of Hilton or
Bally or for making any independent verification of any information reviewed
by it or for making an independent verification of such information.
 
  The DLJ Opinion is necessarily based on economic, market, financial and
other conditions as they existed on, and on the information made available to
it as of, the date of the DLJ Opinion. Although subsequent developments may
affect its opinion, DLJ does not have any obligation to update, revise or
reaffirm its opinion.
 
  The following is a summary of certain factors and the principal financial
analyses performed by DLJ to arrive at its opinion dated as of August 15,
1996. This summary does not purport to be a complete description of the
analyses performed by DLJ. DLJ drew no specific conclusions from any of these
analyses but subjectively factored its observations from these analyses into
its qualitative assessment of the relevant facts and circumstances.
 
  Pro Forma Merger Analysis. DLJ analyzed certain pro forma effects resulting
from the Merger. In conducting its analysis, DLJ relied upon the assumptions
described above and the financial projections provided by the managements of
Hilton and Bally. Using the financial information and projections (normalized
for nonrecurring items) provided to DLJ by Bally's and Hilton's respective
managements, DLJ reviewed the impact on Hilton's 1996, 1997 and 1998 projected
earnings per share resulting from the Merger. DLJ's analysis separately
considered accretion/dilution (i) on an unadjusted basis and (ii) giving
effect to the synergies and other cost reductions estimated by Hilton's and
Bally's management. This analysis revealed that the Merger would be accretive
to 1997 and 1998 projected earnings per share. DLJ also considered the effect
on its analysis of a variance in the Determination Price based on a range from
$80 per share to $120 per share.
 
  Analysis of Certain Other Publicly Traded Companies. To provide contextual
data and comparative market information, DLJ compared selected historical
earnings and operating and financial ratios for Bally to corresponding data
and ratios of certain gaming companies whose securities are publicly traded.
In conducting its analysis, DLJ compared the ratios implied by the
consideration to be paid by Hilton in the transactions contemplated by the
Merger Agreement (the "Transaction") to the ratios implied from the market
valuation of publicly traded companies selected by DLJ (the "Gaming
Companies") based upon qualitative factors which DLJ deemed relevant based
upon its experience in the gaming industry: Aztar Corporation, Circus Circus
Enterprises, Inc., Harrah's Entertainment, Inc., Mirage Resorts, Incorporated,
Showboat, Inc. and Trump Hotels & Casino Resorts, Inc. DLJ also compared the
ratios implied by the consideration to be paid by Hilton in the transactions
contemplated by the Merger Agreement in the Merger to the ratios implied from
the market valuation of a subgroup of the Gaming Companies which included
Circus Circus Enterprises, Inc., Harrah's Entertainment, Inc. and Mirage
Resorts, Incorporated (the "Selected Gaming Companies") based upon the fact
that the Selected Gaming Companies are multi-property, multi-jurisdictional
gaming entities which have similar growth rates and operating performance
characteristics to Bally. Although DLJ used these companies for comparison
purposes, none of such companies is directly comparable to Bally or Hilton.
Data and ratios considered included: the ratio of enterprise value to latest
twelve months ("LTM") revenues; LTM EBITDA; LTM earnings before interest and
taxes ("EBIT"); 1996 projected EBITDA; the ratio of market price to 1996
projected earnings per share; and the ratio of market price to 1997 projected
earnings per share. All projected information for the Gaming Companies was
obtained from Institutional Brokers Estimate Service, a third-party service
which summarizes the estimates made by analysts employed by several investment
banking firms and from the published reports of research analysts employed by
investment banking firms, including analysts employed by DLJ. Enterprise value
is defined as the sum of the principal amount of a company's debt and minority
interests in consolidated subsidiaries plus the market value of its equity
securities less excess cash. EBITDA was selected for analysis by DLJ because
it is a widely used estimate of cash flows generated by operations. EBIT was
selected by DLJ because it is a measure of operating performance. The ratio of
enterprise
 
                                      27

value to LTM revenues ranged from 1.4x to 3.3x for the Gaming Companies and
1.9x to 3.3x for the Selected Gaming Companies, was 3.6x for Hilton and was
2.6x for Bally. The ratio of enterprise value for the Gaming Companies and the
Selected Gaming Companies to LTM EBITDA ranged from 7.5x to 11.5x and 7.5x to
11.5x, respectively, was 11.0x for Hilton and was 8.7x for Bally after giving
effect to operating synergies and other cost reductions. The ratio of
enterprise value for the Gaming Companies and the Selected Gaming Companies to
LTM EBIT ranged from 9.4x to 20.8x and 9.4x to 14.8x, respectively, was 16.9x
for Hilton and was 12.0x for Bally after giving effect to operating synergies
and other cost reductions. The ratio of enterprise value to 1996 projected
EBITDA ranged from 5.5x to 10.5x for the Gaming Companies and 6.3x to 10.5x
for the Selected Gaming Companies, was 10.5x for Hilton and was 7.9x for Bally
after giving effect to operating synergies and other cost reductions. The
ratio of market price to 1996 projected earnings per share ranged from 15.2x
to 21.5x for the Gaming Companies and 15.2x to 21.5x for the Selected Gaming
Companies, was 26.4x for Hilton and was 22.1x for Bally after giving effect to
operating synergies and other cost reductions. The ratio of market price to
1997 projected earnings per share ranged from 12.3x to 20.2x for the Gaming
Companies and 12.3x to 20.2x for the Selected Gaming Companies, was 23.3x for
Hilton and was 15.4x for Bally after giving effect to operating synergies and
other cost reductions. DLJ also separately considered the effects of the
transaction costs associated with the Merger on these ratios.
 
  Comparable Merger and Acquisition Analysis. DLJ reviewed the implied
valuation multiples of: (i) selected merger and acquisition transactions
including the majority of casino hotel company transactions completed since
1984 (the "Casino Resort Transactions"), (ii) Trump Hotels & Casino Resorts,
Inc.'s acquisition of the Trump Taj Mahal Casino Resort in June of 1995 (the
"Taj Mahal Transaction") and (iii) ITT Corporation's acquisition of Caesars
World in 1995 (the "Caesars Transaction"). DLJ made the analysis referred to
in (ii) above because it is the most recent, completed acquisition of an
Atlantic City casino and in (iii) above because it is the most recent,
completed, multi-property, multi-jurisdictional gaming merger and acquisition
transaction with significant Atlantic City operations. Neither the Taj Mahal
Transaction, the Caesars Transaction nor the transactions described in (i)
above, however, are directly comparable to the Merger. Additionally, in
reviewing the multiples in the transactions set forth above, DLJ considered
the effects of the prevailing market conditions. DLJ compared the ratios
implied by the aggregate consideration to be paid by Hilton to the holders of
Bally Common Stock in the Merger (with and without accounting for the
synergies and other cost reductions estimated by Hilton's and Bally's
respective managements) to the ratios implied by mean (calculated excluding
the high and low multiple) of the Casino Resort Transactions, the Taj Mahal
Transaction and the Caesars Transaction. The ratio of enterprise value implied
by the consideration paid to LTM Revenues for the mean of the Casino Resort
Transactions was 1.6x, 1.7x for the Taj Mahal Transaction, 1.8x for the
Caesars Transaction and 2.8x for the Transaction (both with and without giving
effect to synergies and other cost reductions). The ratio of enterprise value
implied by the consideration paid to LTM EBITDA for the mean of the Casino
Transactions was 8.7x, 6.8x for the Taj Mahal Transaction, 9.lx for the
Caesars Transaction, 10.7x in the Transaction without giving effect to
synergies and other cost reductions and 10.0x in the Transaction after giving
effect to synergies and other cost reductions. The ratio of enterprise value
implied by the consideration paid to LTM EBIT was 12.2x for the mean of the
Casino Resort Transactions, 9.9x for the Taj Mahal Transaction, 13.5x for the
Caesars Transaction, 15.2x for the Transaction without giving effect to
synergies and other cost reductions and 13.8x for the Transaction after giving
effect to the synergies and other cost reductions. DLJ also separately
considered the effects of transaction costs associated with the Merger on
these ratios.
 
  Discounted Cash Flow Valuation Analysis. DLJ performed a discounted cash
flow analysis of Bally. DLJ performed its analysis using Bally's management's
estimates of future performance and the future results of operations of Bally.
DLJ selected a range of terminal exit multiples of 8.0 to 10.0 times EBITDA
and a range of weighted average cost of capital from 10.0% to 15.0% based upon
its subjective judgments about, among other things, the capital markets, Bally
prospects and the gaming industry. The terminal exit multiple represents an
estimate of the value of Bally earnings at the end of the three year period
covered by Bally's management's projections and an additional two year period
covered by an extrapolation of Bally's management projections by DLJ. This
analysis implied a per share value of Bally ranging from $30.80 to $51.27.
 
                                      28

  Contribution Analysis. DLJ reviewed the relative contribution to Hilton
after the Merger of Hilton, as a stand alone enterprise, and Bally, as a stand
alone enterprise. DLJ relied upon estimates of 1995, 1996, 1997 and 1998
financial information provided by Hilton's and Bally's respective managements.
Hilton and Bally provided 67.4% and 32.6%, respectively, of the combined
enterprise value. The projections made by Bally's and Hilton's management
reveal, over the four year period, that Hilton would provide from 61.7% to
55.6% of combined revenues; from 67.1% to 60.1% of combined EBITDA and from
65.4% to 57.8% of combined EBIT. On a corresponding basis Bally would provide
from 38.3% to 44.4% of combined revenues, from 32.9% to 39.9% of combined
EBITDA and from 34.6% to 42.2% of combined EBIT. Bally would contribute 12.3%
of tangible book value to the combined company after the Merger.
 
  Premium Analysis. DLJ calculated the premium, represented by multiplying
Hilton's stock price by the Conversion Ratio to Bally's closing stock prices
on the day, week and four weeks prior to June 6, 1996, the date the Merger was
announced, that Hilton will pay to the holders of Bally Common Stock in
connection with the Merger. Based upon Bally's closing stock price of $26.13,
$24.38 and $22.13 on June 5, May 30 and May 9, 1996, respectively, the
Conversion Ratio would have represented premiums of 5.1%, 12.1% and 24.1%,
respectively, for the day before, the week prior to, and four weeks prior to,
the announcement of the Merger. DLJ also examined the premiums paid in recent
transactions of comparable size. The average premium to the closing price of
the common stock of the targets on the day, week and four weeks prior to the
announcement of such transactions was 31.1%, 34.7% and 42.0%, respectively.
 
  Stock Trading Price History. DLJ also reviewed the history of trading prices
for the Bally Common Stock over the last twelve months. Over the 52 weeks
prior to the announcement of the Merger, Bally Common Stock traded between
$26.13 and $9.44 per share and had a price immediately prior to announcement
of the Merger of $26.13 per share. DLJ also reviewed the history of trading
prices for the Bally Common Stock for the periods 90 days and 30 days prior to
the announcement of the Merger. Over the 90 days prior to the announcement of
the Merger, Bally Common Stock traded between $26.13 and $15.50 per share.
Over the 30 days prior to the announcement of the Merger, Bally Common Stock
traded between $26.13 and $19.75 per share.
 
  The summary set forth above does not purport to be a complete description of
the analyses performed and factors considered by DLJ. 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. Accordingly, notwithstanding the
separate factors summarized above, DLJ believes that its analysis 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 view of the evaluation process underlying its opinions.
Furthermore, in arriving at its fairness opinion, DLJ did not attribute any
particular weight to any analysis, or factor considered by it, but rather made
subjective and qualitative judgments as to the significance and relevance of
each analysis and factor. In performing its analyses, DLJ made numerous
assumptions with respect to industry performance, business and economic
conditions and 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, as amended, Hilton has agreed
to pay DLJ (i) an initial retainer fee of $100,000 and (ii) a fee of
$1,000,000 for rendering its fairness opinion. In addition, Hilton has agreed
to pay DLJ $10,000,000, less the amounts set forth in (i) and (ii) above, upon
consummation of the Merger. Additionally, in the event that Hilton does not
consummate the Merger and Hilton receives any termination fees from Bally, DLJ
shall receive $5.0 million (provided that this fee shall not be greater than
10.0% of any payment received from Bally in the event the Merger is not
consummated). Hilton has also agreed to reimburse DLJ for its reasonable out-
of-pocket expenses (including the reasonable fees and expenses of DLJ's
counsel) incurred in connection with its engagement, and to indemnify DLJ and
certain of its related persons against certain 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 arm's length
between Hilton and DLJ. In May 1996, DLJ was the lead manager of an
 
                                      29
<PAGE>
 
offering by Hilton of $500,000,000 of 5% Convertible Subordinated Notes due
2006 for which DLJ received approximately $6,500,000.
 
  In the ordinary course of business, DLJ actively trades the debt and equity
securities of Hilton and Bally 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.
 
OPINIONS OF FINANCIAL ADVISORS TO BALLY
 
  Opinion of Goldman Sachs. On June 6, 1996, Goldman Sachs delivered its oral
opinion to the Bally Board of Directors that, based upon and subject to the
matters set forth therein and based upon such other matters as it considered
relevant, as of the date of such opinion, the Merger Consideration to be
received by the holders of Bally Common Stock pursuant to the Merger Agreement
was fair to such holders. Goldman Sachs subsequently confirmed its oral
opinion by delivering to the Bally Board of Directors its written opinion,
dated as of the date hereof, that, based upon and subject to the matters set
forth therein and based upon such other matters as it considered relevant, as
of the date hereof, the total consideration to be received by the holders of
Bally Common Stock pursuant to the Merger Agreement is fair to such holders.
 
  THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED THE DATE HEREOF,
WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE
REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED TO THIS JOINT
PROXY STATEMENT/PROSPECTUS AS APPENDIX C AND IS INCORPORATED HEREIN BY
REFERENCE. THE GOLDMAN SACHS OPINION IS NECESSARILY BASED ON ECONOMIC, MARKET
AND OTHER CONDITIONS IN EFFECT ON, AND THE INFORMATION MADE AVAILABLE TO IT AS
OF, THE DATE HEREOF. SUBSEQUENT DEVELOPMENTS MAY AFFECT SUCH OPINION. HOLDERS
OF BALLY COMMON STOCK ARE URGED TO READ, AND SHOULD READ, THE GOLDMAN SACHS
OPINION IN ITS ENTIRETY AND CONSIDER IT CAREFULLY. THE FOLLOWING SUMMARY IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION. THE
GOLDMAN SACHS OPINION IS ADDRESSED TO THE BALLY BOARD OF DIRECTORS AND DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER
SHOULD VOTE ON THE PROPOSED MERGER.
 
  In connection with its written opinion, Goldman Sachs reviewed, among other
things, (i) the Merger Agreement; (ii) the Registration Statement on Form S-4,
including this Joint Proxy Statement/Prospectus; (iii) Annual Reports to
Stockholders and Annual Reports on Form 10-K of Bally and Hilton for the five
years ended December 31, 1995; (iv) certain interim reports to stockholders
and Quarterly Reports on Form 10-Q of Bally and Hilton; (v) certain other
communications from Bally and Hilton to their respective stockholders; and
(vi) certain internal financial analyses and forecasts for Bally and Hilton
prepared by Bally's and Hilton's management, respectively, including forecasts
of certain cost savings, operating efficiencies, and financial synergies
(collectively, the "Synergies") expected to be achieved as a result of the
Merger prepared by Bally's management. Goldman Sachs also held discussions
with members of the senior management of Bally and Hilton regarding the past
and current business operations, financial condition and future prospects of
their respective companies and the combined company resulting from the Merger,
and regarding their assessment of the strategic fit and implications of the
Merger and the Synergies. In addition, Goldman Sachs reviewed the reported
price and trading activity for the Bally Common Stock and Hilton Common Stock,
compared certain financial and stock market information for Bally and Hilton
with similar information for certain other companies the securities of which
are publicly traded, reviewed the financial terms of certain recent business
combinations in the gaming and lodging industries specifically and in other
industries generally. Goldman Sachs also reviewed and performed such other
studies and analyses as Goldman Sachs considered appropriate.
 
  Goldman Sachs relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by it or
conveyed to it in discussions with the senior managements of Bally and Hilton
for purposes of its opinion. In addition, Goldman Sachs did not make an
independent evaluation
 
                                      30
<PAGE>
 
or appraisal of the assets and liabilities of Bally or Hilton or any of their
respective subsidiaries and was not furnished with any such evaluation or
appraisal. Goldman Sachs also assumed, with Bally's consent, that the
financial forecasts of Bally and Hilton (and the assumptions and bases
therefor), as well as the Synergies, were reasonably prepared on a basis
reflecting the best currently available judgments and estimates of Bally and
Hilton, as the case may be, and that such Synergies will be realized in the
amounts and at the times projected.
 
  Goldman Sachs did not express any opinion as to the prices at which the
Hilton Common Stock will trade following the consummation of the Merger or the
prices at which the Bally Common Stock or the Hilton Common Stock will trade
between the announcement of and the consummation of the Merger.
 
  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth below, without
considering the analysis as a whole, could create an incomplete view of the
processes underlying Goldman Sachs' opinion. In arriving at its fairness
determination, Goldman Sachs considered the results of all such analyses as a
whole and did not draw any specific conclusions from or with regard to any one
method of analysis. No company or transaction used in such analyses as a
comparison is identical to Bally or Hilton or the contemplated transaction.
The analyses were prepared solely for purposes of Goldman Sachs' providing its
opinion to the Bally Board of Directors as to the fairness of the Merger
Consideration to be received by the holders of Bally Common Stock pursuant to
the Merger and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually may be sold. Analyses based
upon forecasts of future results are not necessarily indicative of actual
future results, which may be significantly more or less favorable than
suggested by such analyses. Because such analyses are inherently subject to
uncertainty being based upon numerous factors or events beyond the control of
the parties or their respective advisors, none of Bally, Hilton, Goldman Sachs
or any other person assumes responsibility if future results are materially
different from those forecast.
 
  As described above, Goldman Sachs' opinion and presentation to the Bally
Board of Directors was one of many factors taken into consideration by the
Bally Board of Directors in making its determination to approve the Merger
Agreement. The following summary does not purport to be a complete description
of the analysis performed by Goldman Sachs and is qualified by reference to
the written opinion of Goldman Sachs set forth in Appendix C hereto.
 
  Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with Bally, having acted as its financial advisor in connection with,
and having participated in certain of the negotiations leading to, the Merger
Agreement. In addition, Goldman Sachs is a full service securities firm and in
the ordinary course of its trading activities may from time to time effect
transactions, for its own account or the account of customers, and hold
positions in securities or options on securities of Bally or Hilton.
 
  In consideration for Goldman Sachs' services as financial advisor to Bally,
Bally has agreed to pay to Goldman Sachs a fee equal to 0.44% of the aggregate
purchase price paid in a business combination transaction involving Bally,
such as the Merger, but in no event less than $8,000,000, payable upon
consummation of such business combination. Bally has also agreed to reimburse
Goldman Sachs for their reasonable out-of-pocket expenses, including fees and
disbursements of their legal counsel, incurred in connection with its
activities as financial advisor to Bally, and to indemnify Goldman Sachs and
certain related persons against certain liabilities in connection with its
engagement, including certain liabilities under the federal securities laws.
 
  Opinion of Merrill Lynch. On June 6, 1996, Merrill Lynch delivered its oral
opinion to the Bally Board of Directors that, on the basis of and subject to
the matters set forth therein, as of the date of such opinion, the proposed
consideration to be received by the holders of Bally Common Stock (other than
Hilton and its affiliates) in the Merger was fair to such holders from a
financial point of view. Merrill Lynch subsequently confirmed its
 
                                      31
<PAGE>
 
June 6, 1996 opinion by delivering to the Bally Board of Directors its written
opinion, dated as of the date hereof, that, on the basis of and subject to the
matters set forth therein, as of the date hereof, the proposed consideration
to be received by the holders of Bally Common Stock (other than Hilton and its
affiliates) in the Merger is fair to such holders from a financial point of
view.
 
  THE FULL TEXT OF THE OPINION OF MERRILL LYNCH DATED THE DATE HEREOF, WHICH
SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW
UNDERTAKEN, IS ATTACHED TO THIS JOINT PROXY STATEMENT/PROSPECTUS AS APPENDIX D
AND IS INCORPORATED HEREIN BY REFERENCE. MERRILL LYNCH'S OPINION IS
NECESSARILY BASED ON ECONOMIC, MARKET AND OTHER CONDITIONS IN EFFECT ON, AND
THE INFORMATION MADE AVAILABLE TO IT AS OF, THE DATE HEREOF. SUBSEQUENT
DEVELOPMENTS MAY AFFECT SUCH OPINION. HOLDERS OF BALLY COMMON STOCK ARE URGED
TO READ THE MERRILL LYNCH OPINION IN ITS ENTIRETY AND CONSIDER IT CAREFULLY.
THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF SUCH OPINION. THE MERRILL LYNCH OPINION IS ADDRESSED TO THE BALLY
BOARD OF DIRECTORS AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER
AS TO HOW SUCH STOCKHOLDER SHOULD VOTE ON THE PROPOSED MERGER.
 
  In arriving at its written opinion, Merrill Lynch, among other things: (i)
reviewed Bally's Annual Reports, Forms 10-K and related financial information
for the five fiscal years ended December 31, 1995 and Bally's Form 10-Q and
the related unaudited financial information for the quarterly period ending
March 31, 1996; (ii) reviewed Hilton's Annual Reports, Forms 10-K and related
financial information for the five fiscal years ended December 31, 1995 and
Hilton's Form 10-Q and the related unaudited financial information for the
quarterly period ending March 31, 1996; (iii) reviewed certain information,
including financial forecasts, relating to the business, earnings, cash flow,
assets and prospects of Bally and Hilton furnished to Merrill Lynch by Bally
and Hilton, respectively, as well as the cost savings and related expenses and
synergies expected to result from the Merger, furnished to Merrill Lynch by
Bally; (iv) conducted discussions with members of senior management of Bally
and Hilton concerning their respective businesses and prospects; (v) reviewed
the historical market prices and trading activity for the Bally Common Stock
and the Hilton Common Stock and compared them with those of certain publicly
traded companies which Merrill Lynch deemed to be reasonably similar to Bally
and Hilton, respectively; (vi) compared the results of operations of Bally and
Hilton with those of certain companies which Merrill Lynch deemed to be
reasonably similar to Bally and Hilton, respectively; (vii) compared the
proposed financial terms of the Merger with the financial terms of certain
other mergers and acquisitions which Merrill Lynch deemed to be relevant;
(viii) considered the pro forma effect of the Merger on the earnings, cash
flow, consolidated capitalization and certain financial ratios of Hilton; (ix)
reviewed the Merger Agreement; (x) reviewed the Registration Statement on Form
S-4, including this Joint Proxy Statement/Prospectus; and (xi) reviewed such
other financial studies and analyses and took into account such other matters
as Merrill Lynch deemed necessary, including its assessment of general
economic, market and monetary conditions.
 
  Merrill Lynch assumed and relied on the accuracy and completeness of all
information supplied or otherwise made available to it by or on behalf of
Bally and Hilton and all information made publicly available by Bally and
Hilton, and did not independently verify such information or undertake an
independent evaluation or appraisal of any of the assets or liabilities of
Bally or Hilton and was not furnished with any such evaluation or appraisal.
In addition, Merrill Lynch did not make any physical inspection of the
properties or assets of Bally or Hilton. With respect to the financial
forecasts furnished by Bally and Hilton, Merrill Lynch assumed that they were
reasonably prepared and reflect the best currently available estimates and
judgment of the management of Bally and Hilton, respectively, as to the
expected future financial performance of Bally and Hilton, respectively, and
of the management of Bally as to the cost savings and related expenses and
synergies expected to result from the Merger. Merrill Lynch further assumed
that the Merger will qualify as a reorganization within the meaning of
Section 368(a) of the Code. Merrill Lynch's opinion is necessarily based upon
market, economic, financial and other conditions as they exist and can be
evaluated as of the date hereof.
 
 
                                      32
<PAGE>
 
  Merrill Lynch did not express any opinion as to the prices at which the
Hilton Common Stock will trade following the consummation of the Merger or the
prices at which the Bally Common Stock or the Hilton Common Stock will trade
between the announcement of and the consummation of the Merger.
 
  In arriving at its opinion, Merrill Lynch performed a variety of financial
analyses, the material portions of which are summarized below. The summary set
forth below does not purport to be a complete description of the analyses
performed by Merrill Lynch. In addition, Merrill Lynch believes that its
analyses must be considered as
a whole and that selecting portions of its analyses and of the factors
considered by it, without considering all such factors and analyses, could
create a misleading view of the process underlying its analyses set forth in
its opinion and its report to the Bally Board of Directors. Merrill Lynch did
not draw any specific conclusions from or with regard to any one method of
analysis. The matters considered by Merrill Lynch in arriving at its opinion
that, as of the date of such opinion, the proposed consideration to be
received by the holders of Bally Common Stock (other than Hilton and its
affiliates) in the Merger is fair to such holders from a financial point of
view, are based on numerous macroeconomic, operating and financial assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond Bally's or Hilton's control. Any
estimates incorporated in the analyses performed by Merrill Lynch are not
necessarily indicative of actual past or future results or values, which may
be significantly more or less favorable than such estimates. Estimated values
do not purport to be appraisals and do not necessarily reflect the prices at
which businesses or companies may be sold in the future, and such estimates
are inherently subject to uncertainty. Arriving at a fairness opinion is a
complex process not necessarily susceptible to partial or summary description.
No public company utilized as a comparison is identical to Bally or Hilton.
Accordingly, an analysis of publicly traded comparable companies and
comparable business combinations is not mathematical; rather it involves
complex considerations and judgments concerning differences in financial and
operating characteristics of the comparable companies and other factors that
could affect the public trading value of the comparable companies or company
to which they are being compared.
 
  The Bally Board of Directors selected Merrill Lynch to render a fairness
opinion because Merrill Lynch is an internationally recognized investment
banking firm with substantial experience in transactions similar to the Merger
and because it is familiar with Bally and its business. Merrill Lynch has, in
the past, provided financial advisory and financing services to Bally and
Hilton and has received fees for the rendering of such services. In addition,
in the ordinary course of its business, Merrill Lynch may actively trade Bally
Common Stock and other securities of Bally, as well as securities of Hilton,
for its own account and for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities.
 
  In consideration for Merrill Lynch's services as financial advisor to Bally,
Bally has agreed to pay to Merrill Lynch a fee equal to 0.22% of the aggregate
purchase price paid in a business combination transaction involving Bally,
such as the Merger, but in no event less than $4,000,000, payable upon
consummation of such business combination. Bally has also agreed to reimburse
Merrill Lynch for its reasonable out-of-pocket expenses, including fees and
disbursements of its legal counsel, incurred in connection with its activities
as financial advisor to Bally, and to indemnify Merrill Lynch and certain
related persons against certain liabilities in connection with its engagement,
including certain liabilities under the federal securities laws.
 
  Financial Analyses. The following is a summary of the material financial
analyses used by Goldman Sachs and Merrill Lynch in connection with their
joint presentation to the Bally Board of Directors with regard to their oral
opinions on June 6, 1996. Such presentation and the following summary thereof
do not reflect the Stock Split. Goldman Sachs and Merrill Lynch, respectively,
relied upon analysis such as those below in connection with providing their
written opinions dated as of the date hereof.
 
  (i) Historical Stock Price Analysis. Goldman Sachs and Merrill Lynch
reviewed the performance of the per share closing market prices of Bally
Common Stock and Hilton Common Stock over the period from June 3, 1991 through
June 3, 1996. Goldman Sachs and Merrill Lynch then compared the movement of
such closing prices for Bally Common Stock with the movement of the Standard &
Poor's 400 Index and with a composite index of certain large capitalization
gaming companies, specifically, Circus Circus Enterprises, Inc., Harrah's
 
                                      33
<PAGE>
 
Entertainment, Inc., ITT Corporation, MGM Grand, Inc., Mirage Resorts,
Incorporated, Trump Hotels & Casino Resorts, Inc. (collectively, the "Large
Cap Gaming Companies") and Hilton. Goldman Sachs and Merrill Lynch also
compared the movement of such closing prices for Hilton Common Stock over the
period from June 3, 1993 through June 3, 1996 with the movement of a composite
index of the Large Cap Gaming Companies, including Bally, and with a composite
index of certain hotel companies, specifically, HFS Incorporated, Host
Marriott Corporation, La Quinta Inns, Inc., Marriott International, Inc., ITT
Corporation and The Promus Companies Incorporated.
 
  Goldman Sachs and Merrill Lynch also reviewed the historical ratios of the
closing market prices of Bally Common Stock to Hilton Common Stock over the
period from June 3, 1993 through June 3, 1996 and compared such ratios with
the Exchange Ratio (defined as the Conversion Number without giving effect to
the Stock Split) of 0.250. Goldman Sachs and Merrill Lynch noted that the
ratio of the closing market prices of Bally Common Stock to Hilton Common
Stock for the one-year period and three-year period ended June 3, 1996 were
0.185 and 0.159, respectively.
 
  (ii) Selected Comparable Companies Analysis. Goldman Sachs and Merrill Lynch
compared certain publicly available financial and operating data and projected
financial performance (based on Institutional Brokers Estimate System
estimates (a composite of research analysts' estimates)) of the Large Cap
Gaming Companies, including Hilton, and certain small capitalization gaming
companies, specifically, Boyd Gaming Corporation, Primadonna Resorts, Inc.,
Showboat, Incorporated, Station Casinos, Inc. and Aztar Corporation
(collectively, the "Small Cap Gaming Companies"), with similar financial and
operating data and projected financial performance of Bally. Data for Bally
was analyzed both at June 5, 1996 (the "June Bally Statistics"), the day
before Goldman Sachs and Merrill Lynch presented their analyses to the Bally
Board of Directors, and at March 28, 1996 (the "March Bally Statistics") , the
day prior to the first public commentary regarding a possible acquisition of
Bally. Such analysis indicated: (a) mean and median values of levered market
capitalization (i.e., market value of common equity plus face value of
preferred stock, debt and minority interest less cash, cash equivalents and
marketable securities) as a multiple of latest twelve months' ("LTM") earnings
before interest, taxes, depreciation and amortization ("EBITDA") of 14.5x and
14.0x, respectively, for the Large Cap Gaming Companies, including Hilton, and
10.4x and 10.8x, respectively, for the Small Cap Gaming Companies (as compared
to corresponding values of 7.2x for Bally based on the March Bally Statistics
and 8.6x for Bally based on the June Bally Statistics); (b) mean and median
values of levered market capitalization as a multiple of LTM earnings before
interest and taxes ("EBIT") of 18.8x and 19.0x, respectively, for the Large
Cap Gaming Companies, including Hilton, and 17.5x and 18.3x, respectively, for
the Small Cap Gaming Companies (as compared to corresponding values of 10.4x
for Bally based on the March Bally Statistics and 12.4x for Bally based on the
June Bally Statistics); (c) based on consensus analysts' estimates, mean and
median 1996 price to earnings multiples of 24.5x and 25.2x, respectively, for
the Large Cap Gaming Companies, including Hilton, and 20.9x and 20.7x,
respectively, for the Small Cap Gaming Companies (as compared to corresponding
values of 21.2x for Bally based on the March Bally Statistics and 30.7x for
Bally based on the June Bally Statistics); (d) mean and median values for
price as a percentage of the 52-week high trading price of 99% and 100% for
the Large Cap Gaming Companies, including Hilton, and 88% and 90% for the
Small Cap Gaming Companies (as compared to corresponding values of 62% for
Bally based on the March Bally Statistics and 100% for Bally based on the June
Bally Statistics); (e) based on consensus analysts' estimates, mean and median
1997 price to earnings multiples of 20.8x, for the Large Cap Gaming Companies,
including Hilton, and 16.lx and 15.8x, respectively, for the Small Cap Gaming
Companies (as compared to corresponding values of 14.9x for Bally based on the
March Bally Statistics and 20.9x for Bally based on the June Bally
Statistics); (f) mean and median consensus analysts' five year earnings per
share growth rate estimates of 18.7% and 18.0%, respectively, for the Large
Cap Gaming Companies, including Hilton, and 19.3% and 19.5%, respectively, for
the Small Cap Gaming Companies (as compared to corresponding values of 15.0%
for Bally based on the March Bally Statistics and 13.5% for Bally based on the
June Bally Statistics); (g) mean and median LTM EBITDA margins (i.e., the
ratio of EBITDA to gross revenues) of 23.4% and 26.4%, respectively, for the
Large Cap Gaming Companies, including Hilton, and 21.5% and 21.9%,
respectively, for the Small Cap Gaming Companies (as compared to corresponding
values of 26.1% for Bally based on the March Bally Statistics and 26.4% for
 
                                      34
<PAGE>
 
Bally based on the June Bally Statistics); and (h) mean and median ratios of
debt (i.e., face value of preferred stock and debt) to levered market
capitalization of 15% and 13%, respectively, for the Large Cap Gaming
Companies, including Hilton, and 39% and 42%, respectively, for the Small Cap
Gaming Companies (as compared to corresponding values of 53% for Bally based
on the March Bally Statistics and 41% for Bally based on the June Bally
Statistics).
 
  Goldman Sachs and Merrill Lynch also compared certain publicly available
financial and operating data and projected financial performance (based on
Institutional Brokers Estimate System estimates) of the Large Cap Gaming
Companies, including Bally, and certain hotel and other companies,
specifically, ITT Corporation, Carnival Corporation, Marriott International,
Inc., La Quinta Inns, Inc., The Promus Companies Incorporated and Doubletree
Corporation (collectively, the "Lodging Companies"), with similar financial
and operating data and projected financial performance of Hilton as of June 5,
1996. Such analysis indicated: (a) mean and median values of levered market
capitalization as a multiple of LTM EBITDA of 14.9x and 13.2x, respectively,
for the Lodging Companies and 13.9x and 14.0x, respectively, for the Large Cap
Gaming Companies, including Bally (as compared to a corresponding value of
12.7x for Hilton); (b) mean and median values of levered market capitalization
as a multiple of LTM EBIT of 18.9x and 17.5x, respectively, for the Lodging
Companies and 18.0x and 19.0x, respectively, for the Large Cap Gaming
Companies, including Bally (as compared to a corresponding value of 17.9x for
Hilton); (c) based on consensus analysts' estimates, mean and median 1996
price to earnings multiples of 23.6x and 23.5x, respectively, for the Lodging
Companies and 24.9x and 25.2x, respectively, for the Large Cap Gaming
Companies, including Bally (as compared to a corresponding value of 27.9x for
Hilton); (d) mean and median values for price as a percentage of the 52-week
high trading price of 96% for the Lodging Companies and 99% and 100%,
respectively, for the Large Cap Gaming Companies, including Bally (as compared
to a corresponding value of 100% for Hilton); (e) based on consensus analysts'
estimates, mean and median 1997 price to earnings multiples of 19.7x for the
Lodging Companies and 20.3x and 20.8x, respectively, for the Large Cap Gaming
Companies, including Bally (as compared to a corresponding value of 24.0x for
Hilton); (f) mean and median consensus analysts' five year earnings per share
growth rate estimates of 20.9% and 21.0%, respectively, for the Lodging
Companies and 18.8% and 18.0%, respectively, for the Large Gap Gaming
Companies, including Bally (as compared to a corresponding value of 13.0% for
Hilton); (g) mean and median LTM EBITDA margins (i.e., the ratio of EBITDA to
gross revenues) of 28.9% and 29.2%, respectively, for the Lodging Companies
and 22.9% and 26.4%, respectively, for the Large Cap Gaming Companies,
including Bally (as compared to a corresponding value of 29.7% for Hilton);
and (h) mean and median ratios of debt to total market capitalization of 14%
and 11%, respectively, for the Lodging Companies and 19% and 15%,
respectively, for the Large Cap Gaming Companies, including Bally (as compared
to a corresponding value of 13% for Hilton).
 
  (iii) Selected Comparable Transaction Analysis. Goldman Sachs and Merrill
Lynch reviewed certain publicly available information regarding the
acquisition of Caesar's World Inc. by ITT Corporation announced on December
19, 1994, which was the only recent acquisition of a large capitalization
public gaming company that Goldman Sachs and Merrill Lynch deemed relevant,
and compared such information to similar information regarding the Merger. The
analysis showed, among other things, that the implied EBITDA transaction
multiples for the Merger exceeded the EBITDA multiples for the Caesars World
transaction, with (a) LTM EBITDA multiples of 9.4x for the Caesars World
transaction and 10.6x for the Merger based on the March Bally Statistics at an
assumed price per share of Hilton Common Stock of $114.00, which approximated
the per share price of Hilton Common Stock immediately prior to the rendering
of the analysis; and (b) an estimated 1995 EBITDA multiple of 8.1x for Caesars
World (based upon then current research estimates) and an estimated 1996
EBITDA multiple of 9.3x for the Merger (based on Bally management's
estimates).
 
  (iv) Review of Implied Transaction Multiples. Goldman Sachs and Merrill
Lynch reviewed certain implied transaction multiples based on the Exchange
Ratio and a range of Hilton Common Stock prices from $80.00 to $116.00 per
share. Based on an assumed price per share of Hilton Common Stock of $114.00,
which approximated the per share price of Hilton Common Stock immediately
prior to the rendering of the analysis, such analysis indicated: (a) with
respect to EBITDA, multiples of 11.3x 1995 EBITDA, 10.6x LTM EBITDA, 9.3x
estimated 1996 EBITDA (based on Bally management's EBITDA estimates), and 7.8x
estimated 1997
 
                                      35
<PAGE>
 
EBITDA (based on Bally management's EBITDA estimates); (b) with respect to
earnings per share, multiples of 54.8x 1995 earnings per share, 30.3x
estimated 1996 earnings per share (based on Bally management's earnings per
share estimates), 19.3x estimated 1997 earnings per share (based on Bally
management's earnings per share estimates), 33.5x estimated 1996 earnings per
share (based on Institutional Brokers Estimate System estimates), and 22.8x
estimated 1997 earnings per share (based on Institutional Brokers Estimate
System estimates); (c) with respect to the weighted average Bally Common Stock
price per share over the period from March 28, 1995 to March 28, 1996, a
premium of 129%; and (d) with respect to the weighted average Bally Common
Stock price over the period from June 5, 1995 to June 5, 1996, a premium of
67%.
 
  (v) Discounted Cash Flow Analysis. Goldman Sachs and Merrill Lynch performed
a discounted cash flow analysis of Bally, on a stand-alone basis, and Hilton,
on a stand-alone basis, based upon estimates of projected financial
performance prepared by the managements of Bally and Hilton, respectively.
Utilizing these
projections, Goldman Sachs and Merrill Lynch calculated a range of implied per
share equity values based upon the discounted net present value of the sum of:
(a) the projected stream of unlevered free cash flows from 1996 to the year
2000; (b) the projected terminal value at such year based upon a range of
multiples of projected EBITDA; and (c) an assumed cash value net of debt.
Goldman Sachs and Merrill Lynch applied several discount rates (ranging from
12% to 18% for Bally and 10% to 16% for Hilton) and multiples of EBITDA
(ranging from 7.0x to 9.0x for Bally and 10.0x to 12.5x for Hilton). Utilizing
this methodology, the implied present value per share of Bally Common Stock
ranged from $18.63 to $37.85, and the implied present value per share of
Hilton Common Stock ranged from $81.71 to $136.34.
 
  (vi) Pro Forma Merger Analysis. Goldman Sachs and Merrill Lynch also
analyzed certain pro forma effects resulting from the Merger based on the
Exchange Ratio, including the potential impact of the Merger on the estimated
earnings per share of Hilton for the years 1996 through 2000. Such analysis
was based on estimates of Bally management on projected annual pre-tax
combination benefits of approximately $37 million. The analysis indicated that
the Merger would be accretive on an earnings per share basis for the years
1996 through 2000. Goldman Sachs and Merrill Lynch also performed a
sensitivity analysis of the potential impact of the Merger on the estimated
earnings per share of Hilton for the years 1996 through 1998, for a range of
prices of Hilton Common Stock from $96.00 to $108.00 per share, at which
levels Hilton would be required to pay an Additional Cash Payment of up to
$3.00 per share to the holders of Bally Common Stock. The Merger remained
accretive on an earnings per share basis for the three years analyzed.
 
  (vii) Pro Forma Contribution Analysis. In addition, Goldman Sachs and
Merrill Lynch compared the relative equity ownership of the stockholders of
Bally and stockholders of Hilton to the combined company of 25.9% and 74.1%,
respectively, to the relative contributions of each of Bally and Hilton to the
combined company for the years 1995 through 1997 to net income, book value as
of March 31, 1996 and equity market capitalization as of March 28, 1996 and
June 5, 1996. Such analysis was based on estimates prepared by Bally
management with respect to Bally and was based on estimates prepared by Hilton
management with respect to Hilton. The analysis indicated, among other things:
that Bally would have contributed approximately 15.6% of the actual 1995 net
income, 24.9% of the estimated 1996 net income and 29.0% of the estimated 1997
net income of the combined company; 18.6% of the March 31, 1996 book value of
the combined company; 19.2% of the equity market capitalization as of March
28, 1996 of the combined company; and 24.6% of the equity market
capitalization as of June 5, 1996 of the combined company. Goldman Sachs and
Merrill Lynch also compared the relative contributions of the stockholders of
Bally and the stockholders of Hilton to the total enterprise value (i.e.,
market value of common equity assuming conversion of preferred stock and
exercise of all in-the-money stock options plus the face value of debt and
minority interest less cash, cash equivalents and marketable securities) of
the combined company of 31.9% and 68.1% to the relative contributions of each
of Bally and Hilton to the combined company for the years 1995 through 1997 to
EBITDA, EBIT and levered market capitalization. Such analysis was based on
estimates prepared by Bally management with respect to Bally and was based on
estimates prepared by Hilton management with respect to Hilton. The analysis
indicated, among other things, that Bally would have contributed approximately
35.1% of the actual 1995 EBITDA, 37.4% of the estimated 1996 EBITDA and 37.1%
of the estimated 1997 EBITDA of the combined company; 34.6% of the
 
                                      36
<PAGE>
 
actual 1995 EBIT, 39.8% of the estimated 1996 EBIT and 39.0% of the estimated
1997 EBIT of the combined company; 27.6% of the levered market capitalization
as of March 28, 1996 of the combined company; and 30.6% of the levered market
capitalization as of June 5, 1996 of the combined company.
 
REGULATORY APPROVALS
 
  Antitrust. Transactions such as the Merger are reviewed by the Antitrust
Division of the United States Department of Justice (the "DOJ") and the United
States Federal Trade Commission (the "FTC") to determine whether they comply
with applicable antitrust laws. Under the provisions of the HSR Act, the
Merger may not be consummated until such time as the applicable waiting period
requirements of the HSR Act have been satisfied. Hilton and Bally filed
notification reports, together with requests for early termination of the
waiting period, with the DOJ and the FTC under the HSR Act on July 17, 1996
and July 12, 1996, respectively. The applicable waiting periods for both
Hilton and Bally expired on August 16, 1996 with no request for additional
information having been made.
 
  At any time before or after the Effective Time, the DOJ, the FTC or a
private person or entity could seek under the antitrust laws, among other
things, to enjoin the Merger or to cause Hilton to divest itself, in whole or
in part, of Bally or of other businesses conducted by Hilton. There can be no
assurance that a challenge to the Merger will not be made or that, if such a
challenge is made, Hilton and Bally will prevail.
 
  Gaming Regulation. The gaming operations of each of Hilton and Bally are
subject to extensive regulation, and each of Hilton and Bally hold gaming
licenses or permits in each jurisdiction in which it operates gaming
activities. In each such jurisdiction, certain regulatory requirements must be
complied with and/or certain approvals must be obtained in connection with the
Merger. Hilton's obligations to consummate the Merger are subject to the
satisfaction or waiver at or prior to the Effective Time of the condition that
all necessary gaming regulatory approvals and authorizations shall have been
obtained. See "The Merger Agreement--Conditions to the Merger."
 
  Review of the Merger by gaming regulatory authorities will involve
examination of the structure of the combined company and its financial
stability after the Merger and may require the demonstration of qualifications
of key individuals associated with the combined company, i.e. officers,
directors, major stockholders and other individuals deemed appropriate by the
gaming regulatory authorities.
 
  The failure to obtain the required approval of the Merger or the failure to
comply with the procedural requirements prescribed by any applicable gaming
regulatory authority or the failure of the combined company to qualify or make
disclosure or applications as required under the laws and regulations of any
applicable gaming regulatory authority may result in the loss of license or
denial of application for licensure in any such jurisdiction. See "Regulation
and Licensing." In addition, in connection with the regulatory approvals to be
obtained in New Jersey in connection with the Merger, the Hilton and Bally
Boards of Directors may choose to consummate the Merger upon the receipt of
interim casino authorization from New Jersey regulators. In the event that
following the consummation of the Merger final casino authorization were
withheld, the New Jersey gaming regulators would have the right to take
remedial action, including action which would result in the divestiture of
Hilton's ownership of the stock of the Bally subsidiaries licensed to operate
in New Jersey. See "Regulation and Licensing--New Jersey Gaming Laws."
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger will be accounted for as a "purchase" in accordance with
generally accepted accounting principles. After the Effective Time of the
Merger, the results of operations of Bally will be included in the
consolidated financial statements of Hilton. On the date that the Merger
becomes effective, the cost of Bally to Hilton, based upon (i) the value of
shares of Hilton Common Stock exchanged for Bally Common Stock and the Hilton
Common Stock equivalent value of Hilton PRIDES exchanged for Bally PRIDES
based on the average of the quoted market prices of Hilton Common Stock (A)
for three day periods both before and after the Merger was announced, or (B)
on the third Trading Day prior to the date upon which the Merger is
consummated in the event any Additional Cash Payment is to be made, in each
case as adjusted for the Stock Split, and (ii) costs
 
                                      37
<PAGE>
 
incurred related to the Merger, will be allocated to the net assets of Bally
acquired based upon their respective estimated fair market values.
 
APPRAISAL RIGHTS
 
  In the event any Additional Cash Payment is made in connection with the
Merger, any holder of Bally Common Stock will have the right to dissent from
the Merger and demand and perfect appraisal rights in accordance with the
conditions established by Section 262 of the DGCL ("Section 262"). While
determination as to whether there will be any Additional Cash Payment will be
made after the Bally Special Meeting, in order to preserve their rights,
stockholders who wish to exercise their statutory appraisal rights must submit
a written demand for appraisal prior to the Bally Special Meeting and comply
with the other procedural requirements of Section 262 described below.
 
  SECTION 262 IS REPRINTED IN ITS ENTIRETY AS APPENDIX E TO THIS JOINT PROXY
STATEMENT/PROSPECTUS. THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF
THE LAW RELATING TO APPRAISAL RIGHTS AND IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO APPENDIX E. THIS DISCUSSION AND APPENDIX E SHOULD BE REVIEWED
CAREFULLY BY ANY HOLDER WHO WISHES TO EXERCISE STATUTORY APPRAISAL RIGHTS, IF
AVAILABLE, OR WHO WISHES TO PRESERVE THE RIGHT TO DO SO, AS FAILURE TO COMPLY
WITH THE PROCEDURES SET FORTH HEREIN OR THEREIN WILL RESULT IN THE LOSS OF
APPRAISAL RIGHTS, IF AVAILABLE.
 
  A record holder of Bally Common Stock who makes the demand described below
with respect to such shares, who continuously is the record holder of such
shares through the Effective Time, who otherwise complies with the statutory
requirements of Section 262 and who neither votes in favor of the Merger
Agreement nor consents thereto in writing may be entitled to an appraisal by
the Delaware Court of Chancery (the "Delaware Court") of the fair value of his
or her shares of Bally Common Stock. All references in this summary of
appraisal rights to a "stockholder" or "holders of shares of Bally Common
Stock" are to the record holder or holders of shares of Bally Common Stock.
Except as set forth herein, stockholders of Bally will not be entitled to
appraisal rights in connection with the Merger. Holders of Bally PRIDES and
stockholders of Hilton will have no appraisal rights in connection with the
Merger.
 
  Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the Bally Special Meeting, not less than 20
days prior to the meeting, each constituent corporation must notify each of
the holders of its stock for which appraisal rights are available that such
appraisal rights are available and include in each such notice a copy of
Section 262. This Joint Proxy Statement/Prospectus shall constitute such
notice to the record holders of Bally Common Stock.
 
  Holders of shares of Bally Common Stock who desire to exercise their
appraisal rights must not vote in favor of the Merger Agreement or the Merger
and must deliver a separate written demand for appraisal to Bally prior to the
vote by the stockholders of Bally on the Merger Agreement and the Merger. A
stockholder who signs and returns a proxy without expressly directing by
checking the applicable boxes on the reverse side of the proxy card enclosed
herewith that his or her shares of Bally Common Stock be voted against the
proposal or that an abstention be registered with respect to his or her shares
of Bally Common Stock in connection with the proposal will effectively have
thereby waived his or her appraisal rights as to those shares of Bally Common
Stock because, in the absence of express contrary instructions, such shares of
Bally Common Stock will be voted in favor of the proposal. Accordingly, a
stockholder who desires to perfect appraisal rights with respect to any of his
or her shares of Bally Common Stock must, as one of the procedural steps
involved in such perfection, either (i) refrain from executing and returning
the enclosed proxy card and from voting in person in favor of the proposal to
approve the Merger Agreement, or (ii) check either the "Against" or the
"Abstain" box next to the proposal on such card or affirmatively vote in
person against the proposal or register in person an abstention with respect
thereto. A demand for appraisal must be executed by or on behalf of the
stockholder of record and must reasonably inform Bally of the identity of the
stockholder of record and that such record stockholder intends thereby to
demand appraisal of the Bally Common Stock. A person having a beneficial
interest in shares of Bally Common Stock that are held of record in the name
of another person, such as a broker, fiduciary or other
 
                                      38
<PAGE>
 
nominee, must act promptly to cause the record holder to follow the steps
summarized herein properly and in a timely manner to perfect whatever
appraisal rights are available. If the shares of Bally Common Stock are owned
of record by a person other than the beneficial owner, including a broker,
fiduciary (such as a trustee, guardian or custodian) or other nominee, such
demand must be executed by or for the record owner. If the shares of Bally
Common Stock are owned of record by more than one person, as in a joint
tenancy or tenancy in common, such demand must be executed by or for all joint
owners. An authorized agent, including an agent for two or more joint owners,
may execute the demand for appraisal for a stockholder of record; however, the
agent must identify the record owner and expressly disclose the fact that, in
exercising the demand, such person is acting as agent for the record owner.
 
  A record owner, such as a broker, fiduciary or other nominee, who holds
shares of Bally Common Stock as a nominee for others, may exercise appraisal
rights with respect to the shares held for all or less than all beneficial
owners of shares as to which such person is the record owner. In such case,
the written demand must set forth the number of shares covered by such demand.
Where the number of shares is not expressly stated, the demand will be
presumed to cover all shares of Bally Common Stock outstanding in the name of
such record owner.
 
  A stockholder who elects to exercise appraisal rights, if available, should
mail or deliver his or her written demand to: Bally Entertainment Corporation,
8700 West Bryn Mawr Avenue, Chicago, Illinois 60631. Attention: James S.
Montana, Jr., Senior Vice President and Secretary.
 
  The written demand for appraisal should specify the stockholder's name and
mailing address, the number of shares of Bally Common Stock owned, and that
the stockholder is thereby demanding appraisal of his or her shares. A proxy
or vote against the Merger Agreement will not by itself constitute such a
demand. Within ten days after the Effective Time, the surviving corporation
must provide notice of the Effective Time to all stockholders who have
complied with Section 262.
 
  Within 120 days after the Effective Time, either the surviving corporation
or any stockholder who has complied with the required conditions of Section
262 may file a petition in the Delaware Court, with a copy served on the
surviving corporation in the case of a petition filed by a stockholder,
demanding a determination of the fair value of the shares of all dissenting
stockholders. There is no present intent on the part of Hilton to file an
appraisal petition and stockholders seeking to exercise appraisal rights
should not assume that the surviving corporation will file such a petition or
that the surviving corporation will initiate any negotiations with respect to
the fair value of such shares. Accordingly, Bally stockholders who desire to
have their shares appraised should initiate any petitions necessary for the
perfection of their appraisal rights within the time periods and in the manner
prescribed in Section 262. If appraisal rights are available, within 120 days
after the Effective Time, any stockholder who has theretofore complied with
the applicable provisions of Section 262 will be entitled, upon written
request, to receive from the surviving corporation a statement setting forth
the aggregate number of shares of Bally Common Stock not voting in favor of
the Merger Agreement and with respect to which demands for appraisal were
received by Bally and the number of holders of such shares. Such statement
must be mailed within 10 days after the written request therefor has been
received by the surviving corporation.
 
  If a petition for an appraisal is timely filed and assuming appraisal rights
are available, at the hearing on such petition, the Delaware Court will
determine which stockholders, if any, are entitled to appraisal rights. The
Delaware 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 Delaware Court may dismiss the proceedings as to such
stockholder. Where proceedings are not dismissed, the Delaware Court will
appraise the shares of Bally Common Stock owned by such stockholders,
determining the fair value of such shares exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest, if any, to be paid upon the amount determined to be the
fair value. In determining fair value, the Delaware Court is to take into
account all relevant factors. In Weinberger v. UOP Inc., the Delaware Supreme
Court discussed the factors that could be considered in determining fair value
in an appraisal proceeding, stating that "proof of value by any techniques or
methods which are generally
 
                                      39
<PAGE>
 
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that in making this determination of fair value
the court must consider 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 merger which throw light on future prospects
of the merged corporation. In Weinberger, the Delaware Supreme Court stated
that "elements of future value, including the nature of the enterprise, which
are known or susceptible of proof as of the date of the merger and not the
product of speculation, may be considered." Section 262, however, provides
that fair value is to be "exclusive of any element of value arising from the
accomplishment or expectation of the merger."
 
  Holders of shares of Bally Common Stock 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 cost of the appraisal proceeding may be
determined by the Delaware Court and taxed against the parties as the Delaware
Court deems equitable in the circumstances. Upon application of a dissenting
stockholder of Bally, the Delaware Court may order that all or a portion of
the expenses incurred by any dissenting stockholder in connection with the
appraisal proceeding, including, without limitation, reasonable attorney's
fees and the fees and expenses of experts, be charged pro rata against the
value of all shares of stock entitled to appraisal.
 
  Any holder of shares of Bally Common Stock who has duly demanded appraisal
in compliance with Section 262 will not, after the Effective Time, be entitled
to vote for any purpose any shares subject to such demand or to receive
payment of dividends or other distributions on such shares, except for
dividends or distributions payable to stockholders of record at a date prior
to the Effective Time.
 
  At any time within 60 days after the Effective Time, any stockholder will
have the right to withdraw such demand for appraisal and to accept the terms
offered in the Merger; after this period, the stockholder may withdraw such
demand for appraisal only with the consent of the surviving corporation. If no
petition for appraisal is filed with the Delaware Court within 120 days after
the Effective Time, stockholders' rights to appraisal shall cease, and all
holders of shares of Bally Common Stock will be entitled to receive the
consideration offered pursuant to the Merger Agreement. Inasmuch as the
surviving corporation has no obligation to file such a petition, and Hilton
has no present intention to do so, any holder of shares of Bally Common Stock
who desires such a petition to be filed is advised to file it on a timely
basis. Any stockholder may withdraw such stockholder's demand for appraisal by
delivering to the surviving corporation a written withdrawal of his or her
demand for appraisal and acceptance of the Merger, except (i) that any such
attempt to withdraw made more than 60 days after the Effective Time will
require written approval of the surviving corporation and (ii) that no
appraisal proceeding in the Delaware Court shall be dismissed as to any
stockholder without the approval of the Delaware Court, and such approval may
be conditioned upon such terms as the Delaware Court deems just.
 
RESALE OF HILTON STOCK
 
  All shares of Hilton Common Stock and Hilton PRIDES received by holders of
Bally Common Stock and Bally PRIDES in the Merger will be freely transferable,
except that shares of Hilton Common Stock received by persons deemed to be
"affiliates" (as defined under the Securities Act) of Bally at the Effective
Time may be resold only in certain permitted circumstances set forth in Rules
144 and 145 under the Securities Act. This Joint Proxy Statement/Prospectus
does not cover resales of Hilton Common Stock received by any person who may
be deemed to be an affiliate of Bally.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion is a general summary of the material United States
Federal income tax consequences of the Merger. This discussion is based upon
the Code, regulations, proposed or promulgated thereunder, judicial precedent
relating thereto, and current rulings and administrative practice of the
Internal Revenue Service (the "Service"), in each case as in effect as of the
date hereof and all of which are subject to
 
                                      40
<PAGE>
 
change at any time, possibly with retroactive effect. It is assumed that
shares of Bally Common Stock and shares of Bally PRIDES are held as "capital
assets" within the meaning of Section 1221 of the Code (i.e., property held
for investment). This discussion does not address all aspects of Federal
income taxation that might be relevant to particular holders of Bally Common
Stock and Bally PRIDES in light of their status or personal investment
circumstances; nor does it discuss the consequences to such holders who are
subject to special treatment under the Federal income tax laws, such as
foreign persons, dealers in securities, regulated investment companies, life
insurance companies, other financial institutions, tax-exempt organizations,
pass-through entities, taxpayers who hold Bally Common Stock and Bally PRIDES
as part of a "straddle," "hedge" or "conversion transaction" or who have a
"functional currency" other than the United States dollar. In addition, this
discussion does not address the tax consequences to holders of options under
the Bally stock option plans or other persons who have received their Bally
Common Stock as compensation. Neither Hilton nor Bally has requested or will
receive a ruling from the Service as to the tax consequences of the Merger.
 
  HOLDERS OF BALLY COMMON STOCK AND BALLY PRIDES SHOULD CONSULT THEIR TAX
ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY FEDERAL, STATE, LOCAL AND
FOREIGN INCOME AND OTHER TAX LAWS.
 
TAX CONSEQUENCES OF THE MERGER
 
  The Merger is intended to qualify as a reorganization under Section 368(a)
of the Code. It is a condition to the obligation of Hilton to consummate the
Merger that Hilton shall have received an opinion from Latham & Watkins to the
effect that the Merger will be treated as a reorganization within the meaning
of Section 368(a) of the Code and that no gain or loss will be recognized by
Hilton or Bally as a result of the Merger. It is a condition to the obligation
of Bally to consummate the Merger that Bally shall have received an opinion
from Weil, Gotshal & Manges LLP to the effect that the Merger will be treated
as a reorganization within the meaning of Section 368(a) of the Code and that
no gain or loss will be recognized by a holder of Bally Common Stock or Bally
PRIDES as a result of the Merger except (i) with respect to cash received by
such holder in lieu of fractional shares; and (ii) if a holder of Bally Common
Stock receives the Additional Cash Payment, gain, if any, realized by a holder
of Bally Common Stock pursuant to the Merger will be recognized, but not in
excess of the Additional Cash Payment received. In rendering such opinions,
counsel to each of Hilton and Bally will rely upon certain representations
made by Hilton, Bally, and certain stockholders of Bally.
 
  Assuming the Merger is treated as a reorganization within the meaning of
Section 368(a) of the Code, no gain or loss will be recognized for Federal
income tax purposes by Hilton or Bally as a result of the Merger. Subject to
the discussion under "Receipt of Additional Cash Payment" below and except as
described below with respect to cash received in lieu of fractional shares, a
holder of Bally Common Stock or Bally PRIDES will not recognize gain or loss
on the exchange of shares of Bally Common Stock or Bally PRIDES for Hilton
Common Stock or Hilton PRIDES, respectively, pursuant to the Merger. The
aggregate tax basis of the Hilton Common Stock and Hilton PRIDES received by
such holder will be the same as the aggregate tax basis of the Bally Common
Stock and Bally PRIDES surrendered therefor (reduced by the amount of such tax
basis allocable to fractional shares for which cash is received and adjusted
as provided for below in the event the Additional Cash Payment is received).
The holding period of the Hilton Common Stock and Hilton PRIDES will include
the holding period of the Bally Common Stock and Bally PRIDES surrendered
therefor.
 
  Receipt of Additional Cash Payment. If holders of Bally Common Stock receive
the Additional Cash Payment pursuant to the Merger, a holder of Bally Common
Stock will realize gain or loss equal to the difference between (i) the sum of
the Additional Cash Payment and the fair market value of the Hilton Common
Stock received; and (ii) the aggregate tax basis in Bally Common Stock
surrendered therefor. However, any such loss will not be recognized, and any
such gain will only be recognized to the extent of the Additional Cash Payment
received. For this purpose, gain or loss must be calculated separately for
each identifiable block of shares of Bally Common Stock surrendered in the
Merger, and a loss realized on one block of shares of Bally Common Stock
cannot be used to offset a gain realized on another block of shares of Bally
Common Stock. Any such
 
                                      41

gain recognized generally will be treated as capital gain and will be long-
term if the Bally Common Stock surrendered in the Merger has been held for
more than one year at the Effective Time unless the Additional Cash Payment
received has the effect of the distribution of a dividend, in which case the
gain would be treated as a dividend, taxable as ordinary income, to the extent
of the holder's share of Bally's accumulated earnings and profits.
 
  For purposes of determining whether the Additional Cash Payment received has
the effect of the distribution of a dividend, the holder is treated as if such
holder first exchanged all of such holder's Bally Common Stock and, if
applicable, Bally PRIDES, solely for Hilton Common Stock and, if applicable,
Hilton PRIDES, respectively, and then Hilton immediately redeemed (the "deemed
Hilton redemption") a portion of such Hilton Common Stock in exchange for the
Additional Cash Payment the holder actually received. Under this analysis, in
general, if the receipt of the Additional Cash Payment in this deemed Hilton
redemption by a holder of Bally Common Stock results in a "substantially
disproportionate" reduction in such holder's interest in Hilton or is "not
essentially equivalent to a dividend", the receipt of the Additional Cash
Payment will not have the effect of the distribution of a dividend. For
purposes of this determination, the holder's interest in Hilton before the
deemed Hilton redemption is compared to such holder's interest in Hilton after
the deemed Hilton redemption, taking into account in each case any Hilton
stock constructively owned by such holder as a result of the application of
the attribution rules of Section 318 of the Code. If (taking into account
actual ownership and ownership by attribution) the holder's interest in the
voting stock of Hilton has declined, as a result of the deemed Hilton
redemption, by more than 20 percent, then the receipt of the Additional Cash
Payment will not be taxed as a dividend. If such interest in the voting stock
of Hilton has declined, as a result of the deemed Hilton redemption, by 20
percent or less, then generally, in the case of a minority shareholder who is
neither an officer or director of Hilton or who exercises no control over
Hilton's corporate affairs, the receipt of the Additional Cash Payment likely
would not be taxed as a dividend. Holders of Bally Common Stock should consult
with their own tax advisors as to whether the receipt of the Additional Cash
Payment has the effect of a distribution of a dividend, and, if so, the
consequences thereof.
 
  The aggregate tax basis of the Hilton Common Stock received by a holder of
Bally Common Stock who receives an Additional Cash Payment will be the same as
the aggregate tax basis of the Bally Common Stock surrendered therefor,
decreased by the Additional Cash Payment received (and cash received in lieu
of fractional shares) and increased by any recognized gain (whether capital
gain or dividend income). The holding period of the Hilton Common Stock will
include the holding period of the Bally Common Stock surrendered therefor.
 
  Cash In Lieu of a Fractional Share. Cash received by a holder of Bally
Common Stock in lieu of a fractional share interest in Hilton Common Stock
will be treated as received in exchange for such fractional share interest,
and gain or loss will be recognized for Federal income tax purposes, measured
by the difference between the amount of cash received and the portion of the
basis of the Bally Common Stock allocable to such fractional share interest.
Such gain or loss will be capital gain or loss and will be long-term if such
share of Bally Common Stock has been held for more than one year at the
Effective Time.
 
  Certain Foreign Holders. While as set forth above, this general discussion
does not address the special treatment of foreign persons under the Federal
income tax laws, holders of Bally Common Stock and Bally PRIDES who are
foreign persons are urged to consult their tax advisors concerning the effect
of special rules which, depending on their particular facts and circumstances,
may be applicable to them upon consummation of the Merger if Bally is or has
been a "United States real property holding company" within the meaning of
Section 897(c)(2) of the Code.
 
  Backup Withholding. Under the Code, a holder of Bally Common Stock may be
subject, under certain circumstances, to backup withholding at a 31% rate with
respect to the amount of the Additional Cash Payment, if any, received
pursuant to the Merger unless such 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 Service.

ownership and disposition of Hilton PRIDES issuable in the Merger, see
"Description of the Hilton PRIDES--Certain Federal Income Tax Considerations"
and "Description of the Hilton PRIDES--Certain Federal Income Tax
Considerations for Non-U.S. Holders."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the Merger, Bally stockholders should be aware that Bally's
directors and certain members of Bally's management have interests in the
Merger different from, or in addition to, the interests of Bally stockholders
generally.
 
  Executive Officer Employment Agreements. All ten executive officers of Bally
have employment agreements that provide for certain benefits if a "Change in
Control" of Bally (as defined in each employment agreement) occurs and the
executive officer's employment terminates either by (i) an involuntary
termination by Bally or its successor without "Cause" or in a "constructive
termination" or (ii) in certain cases, a voluntary termination by the
executive. For purposes of these agreements, a "Change in Control" will occur
by reason of the Merger. If a qualifying termination occurs, the executive
officer would be entitled to receive termination benefits as set forth below.
 
  Under Mr. Goldberg's employment agreement, if his employment is terminated
(either by him or by Hilton) for any reason during the two-year period
following the Change in Control, Mr. Goldberg would be entitled to receive a
lump sum payment equal to the greater of (i) the sum of his base salary for
the remainder of his employment term, plus the average of the semi-annual
bonuses awarded to him prior to his termination multiplied by two times the
number of half-years remaining in his employment term or (ii) three times his
base salary. In such event, he would also be entitled to any bonuses awarded
but not yet paid, the value of his continued participation in certain employee
benefit plans of Bally (or continued participation in such plans until the end
of the employment term or the time Mr. Goldberg receives equivalent coverage
from a subsequent employer), certain retirement trust contributions and
payment by Bally of premiums on his split-dollar life insurance policy as if
Mr. Goldberg had been employed by Bally until age 62. Because Mr. Goldberg's
employment will terminate at the Effective Time (which for this purpose is
presumed to be November 1, 1996) when he commences the rendering of consulting
services to Hilton pursuant to a consulting agreement (see "--Consulting
Agreement" below), he will receive payments under his employment agreement of
approximately $15,821,000.
 
  Under Mr. Hillman's employment agreement, if he voluntarily terminates his
employment agreement following a Change in Control, he would be entitled to
receive a lump sum payment equal to six months of base salary. If, however,
Hilton terminates Mr. Hillman's employment agreement without "cause" (as
defined in the employment agreement) or "constructively terminates" Mr.
Hillman's employment, he would be entitled to receive (i) a lump sum payment
equal to 36 months of base salary and (ii) a payment equal to two times the
average of the bonuses paid with respect to the prior three years. If Mr.
Hillman's employment agreement is terminated by Hilton at the Effective Time
(which for this purpose is presumed to be November 1, 1996) without "cause" or
as a result of a "constructive termination," he would be entitled to receive
payments under his employment agreement of $1,833,334; if Mr. Hillman's
employment agreement is voluntarily terminated by him following the Effective
Time, he would be entitled to receive payments under his employment agreement
of $200,000.
 
  Under the employment agreements for James S. Montana, Jr., Wallace R. Barr
and Darrell A. Luery, if the executive officer's employment agreement is
voluntarily terminated by the executive officer following a Change in Control,
he would be entitled to receive a lump sum payment equal to six months of base
salary; however, if Hilton terminates the executive officer's employment
agreement without "cause" (as defined in the respective employment agreement)
or "constructively terminates" the executive officer's employment, the
executive officer would be entitled to receive (i) a lump sum payment equal to
the greater of (x) 24 months of base salary or (y) base salary for the
remainder of the employment term, and (ii) a payment equal to the greater of
(a) the prior year's bonus or (b) the average of the bonuses paid with respect
to the prior two years (in the case of
 
                                      43
<PAGE>
 
Mr. Montana) or the prior three years (in the case of Mr. Barr or Mr. Luery).
If the employment agreement of Mr. Montana, Barr or Luery is terminated by
Hilton at the Effective Time (which for this purpose is presumed to be
November 1, 1996) without "cause" or as a result of a "constructive
termination," the executive officer would be entitled to receive payments
under his employment agreement of $650,000, $2,600,000, and $1,417,500,
respectively; if the employment agreement of Mr. Montana, Barr or Luery is
voluntarily terminated by the executive officer following the Effective Time,
he would be entitled to receive payments under his employment agreement of
$150,000, $450,000, and $283,500, respectively.
 
  Under the employment agreements for Robert G. Conover, John W. Dwyer, Harold
Morgan, Bernard J. Murphy and Jerry Thornburg, if Hilton terminates the
executive officer's employment agreement without "Cause" (as defined in the
respective employment agreement), the executive officer would be entitled to
receive (i) a lump sum payment equal to the greater of (x) 24 months of base
salary or (y) base salary for the remainder of the employment term, and (ii) a
payment equal to the greater of (a) the prior year's bonus or (b) the average
of the bonuses paid with respect to the prior three years. If the employment
agreement of Mr. Conover, Dwyer, Morgan, Murphy or Thornburg is terminated by
Hilton at the Effective Time (which for this purpose is presumed to be
November 1, 1996), without "cause," the executive officer would be entitled to
receive payments under his employment agreement of $725,000, $697,500,
$464,000, $375,000 and $347,000, respectively.
 
  Excise Tax Reimbursement Payments. In addition to the Change in Control
payments described above, the Bally Board of Directors approved certain
amendments to the employment agreements of Messrs. Goldberg, Hillman, Barr and
Luery with respect to the existing obligation by Bally to make tax-
reimbursement payments to any of these executive officers if he incurs an
excise tax liability under Section 4999 of the Code, as well as the additional
income and excise taxes liability due to such tax reimbursement payment,
resulting from a Change in Control. Generally, the amendments expanded the
tax-reimbursement payment provision in their employment agreements to include
the payment of compensation other than salary and bonus (such as the
accelerated vesting of stock options) in determining the amount of such tax-
reimbursement payment. In addition, the Bally Board of Directors adopted the
Executive Tax Reimbursement Plan which provides for similar tax-reimbursement
payments to be made by Bally to any member of a select group of executives who
incurs such excise tax liability under Section 4999 of the Code. This group of
27 executives includes all executive officers and certain other officers and
employees with employment agreements which have change-in-control provisions.
For purposes of these agreements and plan, a Change in Control will occur by
reason of the Merger. With respect to the termination of Mr. Goldberg's
employment, it is expected that his excise tax reimbursement payment will be
approximately $5,186,000; with respect to the other executive officers,
assuming that Hilton terminates the employment of such executive officers as
of November 1, 1996, it is expected that the aggregate excise tax
reimbursement payment would be approximately $2,299,000. Because the
calculation of excise tax reimbursement payments is dependent upon specific
facts and circumstances at the time a Change in Control payment is made, the
foregoing amounts are only estimates.
 
  Retirement Plans. On September 7, 1994, Bally adopted the Bally
Entertainment Corporation Management Retirement Savings Plan for a select
group of management or highly compensated employees. The plan provides for
employee contributions, which are 100 percent vested when contributed, and
employer matching contributions, which vest over a three-year period, to be
credited to a participant's account. Under the plan, participants will become
100 percent vested in all employer matching contributions credited to his or
her account not later than five days following a Change in Control of Bally
(as defined in the plan). In addition, Bally will fund these interests through
a grantor trust (if such interests have not already been funded) not later
than five days following a Change in Control. For purposes of this plan, a
Change in Control will occur by reason of the Merger. As of June 28, 1996, the
aggregate amount of the unvested accounts for all executive officers under the
plan which will become vested at the Effective Time due to the Merger is
approximately $653,000.
 
  Stock Option Plans. Under Bally's 1989 Incentive Plan and 1993 Non-
Employees' Director Stock Option Plan, if a Change in Control of Bally (as
defined in the applicable plan) occurs, outstanding stock options and/or
tandem stock appreciation rights will become fully vested on the fifth day
preceding the date of the Change in
 
                                      44
<PAGE>
 
Control. As of July 31, 1996, the executive officers of Bally (in the
aggregate) held vested and unvested options to purchase an aggregate of
3,643,500 shares of Bally Common Stock (500,000 of the options include tandem
stock appreciation rights). In addition, as of July 31, 1996, the non-employee
directors of Bally (as a group) held vested and unvested options to purchase
an aggregate of 63,332 shares of Bally Common Stock. The treatment of such
options and stock appreciation rights is described under "The Merger
Agreement--Treatment of Stock Options." Assuming the amount payable with
respect to each share of Bally Common Stock underlying each option/stock
appreciation right is determined based on the closing sale price of Hilton
Common Stock of $111.00 on August 12, 1996, if all such options/stock
appreciation rights are exercised for the difference between such amount and
the aggregate exercise price under such options/stock appreciation rights, the
aggregate amount payable to all executive officers would be $84,919,322 and
the aggregate amount payable to all non-employee directors would be
$1,157,432.
 
  Hilton has agreed to honor all of the foregoing commitments with respect to
(i) termination payments under the employment agreements, (ii) excise tax
reimbursement payments under the employment agreements and the Executive Tax
Reimbursement Plan, (iii) acceleration of vesting of interests under the
Management Retirement Savings Plan and (iv) acceleration of the vesting of
stock options under the stock option plans.
 
  Stock Ownership. As of July 31, 1996, the executive officers and directors
of Bally in the aggregate beneficially owned an aggregate of 988,999 shares of
Bally Common Stock (excluding shares subject to outstanding stock options) and
10,000 shares of Bally PRIDES. All such shares will be treated in the Merger
in the same manner as the Bally Common Stock and the Bally PRIDES held by
other stockholders of Bally.
 
  Preferred Stock. Pursuant to the Merger Agreement, Bally Casino, all of the
outstanding shares of common stock of which is owned by Bally, will be merged
with and into Bally immediately prior to the Merger (the "Subsidiary Merger"),
with Bally as the surviving corporation. At the effective time of the
Subsidiary Merger (the "Subsidiary Effective Time"), all outstanding shares of
Bally Casino's common stock will be cancelled and all outstanding shares of
Bally Casino's Series A Cumulative Exchangeable Preferred Stock (the
"Subsidiary Preferred Stock") will be converted into the right to receive a
number of shares of Bally Common Stock (rounded-up to the nearest whole
number) equal to the sum of: (i) the number of shares of Bally Common Stock
exchangeable for the Subsidiary Preferred Stock pursuant to the present terms
of the Subsidiary Preferred Stock, and (ii) the number of shares of Bally
Common Stock equal to the quotient of (A) the product of (1) the average of
the last sale prices of the common stock of Bally Total Fitness Holding
Corporation ("Bally Fitness") quoted on the Nasdaq National Market for the
thirty consecutive trading days ending on the third trading day prior to the
Subsidiary Effective Time, and (2) the number of shares of common stock of
Bally Fitness transferable pursuant to the present terms of the Subsidiary
Preferred Stock upon exchange of such Subsidiary Preferred Stock immediately
prior to the Subsidiary Effective Time, divided by (B) the average of the last
sale prices of Bally Common Stock quoted on the NYSE for the thirty
consecutive trading days ending on the third trading day prior to the
Subsidiary Effective Time. All shares of Bally Common Stock issuable in the
Subsidiary Merger shall be deemed issued and outstanding immediately prior to
the Effective Time. As of August 12, 1996, Mr. Goldberg beneficially owned all
of the 1,685,994 shares of Subsidiary Preferred Stock which are exchangeable
for 1,505,405 shares of Bally Common Stock and 376,351 shares of common stock
of Bally Fitness. Based on the closing sale price of Bally Common Stock of
$27.62 on August 12, 1996 and the last sale price of common stock of Bally
Fitness of $4.34 on August 12, 1996, Mr. Goldberg would be entitled to receive
a total of 1,564,582 shares of Bally Common Stock in exchange for his shares
of Subsidiary Preferred Stock at the Subsidiary Effective Time. All such
shares of Bally Common Stock will be converted into the right to receive
shares of Hilton Common Stock in the Merger.
 
  Indemnification Agreements. See "The Merger Agreement--Indemnification" for
a description of provisions of the Merger Agreement relating to the
indemnification of officers and directors of Bally. Also, under the Merger
Agreement, Hilton has agreed that it will, for a period of one year following
the Effective Time, continue to maintain employee benefit plans and
arrangements which are substantially comparable in value (excluding the value
of any benefits under equity based plans) to those currently in effect for
Bally employees.
 
                                      45
<PAGE>
 
  Other Transactions. In addition, the Bally Board of Directors authorized the
following actions to take place immediately prior to the Effective Time and
subject to the consummation of the Merger: (i) in accordance with Hilton's
desire to terminate all relationships with Bally Fitness after the Effective
Time, Bally will sell to Mr. Goldberg and/or his assigns, for a purchase price
of $250,000, Bally's warrant to purchase shares of common stock of Bally
Fitness, which purchase price represents the book value of such warrant; (ii)
in order to ensure Mr. Goldberg's continued participation and the success of
Bally's investment in certain harness racing facilities in the State of
Maryland, Bally will transfer to Mr. Goldberg 20% of Bally's 50% interest and
right to participate in such Maryland racetrack project, on the same terms and
conditions applicable to Hilton as the successor to Bally to the extent Hilton
elects to pursue such racetrack project; (iii) in order to ensure Mr.
Goldberg's continued participation in and the success of Bally's proposed
gaming venture in Cancun, Mexico, Bally will transfer to Mr. Goldberg 40% of
Bally's 50% interest in such Cancun project to the extent Hilton elects to
pursue such project and, until the Effective Time, not make any further
commitment in excess of $5,000 without Hilton's prior approval; and (iv) in
accordance with Hilton's desire to terminate all relationships with Bally
Fitness following the Effective Time and in order to ensure the financial
viability of Bally Fitness which was spun-off to Bally's stockholders in
January 1996, Bally will forgive approximately $15.2 million of indebtedness
of Bally Fitness to Bally. Bally's expenditures in the Maryland racetrack
project and the Cancun project were approximately $500,000 in the aggregate.
As of the date hereof, the executive officers and directors of Bally
beneficially owned less than 5% of the outstanding shares of Bally Fitness
(excluding the shares subject to the warrant being transferred to Mr. Goldberg
described above and excluding the shares which would have been exchangeable
for the Subsidiary Preferred Stock described above). Hilton has consented to
these transactions under the Merger Agreement.
 
  Hilton has agreed to create an advisory board comprised of the current
members of the Bally Board of Directors who will each receive as compensation
for serving on such advisory board a fee of $50,000. Such advisory board will
assist in transition matters after the Effective Time for a period of one
year. Mr. Goldberg will serve as an ex officio member of the advisory board
and will not receive the advisory board fee of $50,000.
 
  Consulting Agreement. Although it is not intended that Mr. Goldberg will
become an employee of Hilton following the Effective Time, Hilton recognizes
that Mr. Goldberg possesses special expertise and knowledge which can benefit
Hilton in the future. Accordingly, based on Hilton's desires to benefit from
Mr. Goldberg's expertise and knowledge after the Effective Time, Hilton and
Mr. Goldberg have entered into a consulting agreement, pursuant to which Mr.
Goldberg will be retained as a consultant to Hilton for a term of three years,
at $2 million per year. Mr. Goldberg will be provided with the use of an
office, secretary, chauffeured car, hotel suites, and company plane for the
term of the consulting agreement, and health insurance benefits until age 62
and will be granted an option to purchase 600,000 shares of Hilton Common
Stock, after giving effect to the Stock Split, at the Effective Time and on
each of the first and second anniversaries of the Effective Time during the
term of the consulting agreement. Mr. Goldberg's stock options will have a per
share exercise price equal to the average of the high and low prices of the
Hilton Common Stock on the date of grant, will be fully exercisable on the
date of grant and will have a term of 5 years, unless Mr. Goldberg voluntarily
terminates the consulting agreement, in which case each option will expire on
the 180th day after the date of termination. In addition, the consulting
agreement provides for Mr. Goldberg to receive tax-reimbursement payments if
he incurs an excise tax liability under Section 4999 of the Code, as well as
the additional income and excise tax liability due to such tax-reimbursement
payments.
 
  Bally's Grand, Inc. In 1995, Bally's Grand, Inc., a majority owned
subsidiary of Bally, announced its intention to develop a separate casino
hotel resort with a Paris, France theme (the "Paris Casino-Resort") on
approximately 24 acres of land situated on the Strip adjacent to Bally's Las
Vegas. In August 1996, Bally agreed to acquire the subsidiary of Bally's
Grand, Inc. that owns and is developing the land expected to be utilized for
the construction of the Paris Casino-Resort in exchange for shares of Bally
Common Stock and cash having an aggregate value of approximately $60 million.
Bally currently expects to issue approximately 1,600,000 shares of Bally
Common Stock in connection with this acquisition.

                             THE MERGER AGREEMENT
 
  The following is a brief summary of certain provisions of the Merger
Agreement, which is attached as Appendix A to this Joint Proxy
Statement/Prospectus and is incorporated herein by reference. Such summary is
qualified in its entirety by reference to the Merger Agreement.
 
TERMS OF THE MERGER
 
  The Merger Agreement provides that, following the approval and adoption of
the Merger Agreement by the stockholders of Hilton and Bally and the
satisfaction or waiver of the other conditions to the Merger, Bally will be
merged with and into Hilton, and Hilton shall continue as the surviving
corporation. As a result of the Merger, Bally shall cease to exist and Hilton
shall succeed to and assume all rights and obligations of Bally in accordance
with the DGCL.
 
EFFECTIVE TIME
 
  The Merger Agreement provides that, subject to the requisite approval of the
stockholders of Bally and Hilton, and subject to the satisfaction or waiver of
certain other conditions, the Merger will be consummated by the filing of a
Certificate of Merger with the Secretary of State of the State of Delaware.
The Merger will become effective at the time of filing, or at such a time
thereafter as is provided in the Certificate of Merger (the "Effective Time").
 
CONVERSION OF SHARES
 
  At the Effective Time, pursuant to the Merger Agreement (subject to the
matters discussed under "The Merger--Appraisal Rights"):
 
    (i) Each share of Bally Common Stock outstanding immediately prior to the
  Effective Time will be converted into the right to receive one (1) share of
  Hilton Common Stock, after giving effect to the Stock Split; provided,
  however, if the Determination Price is less than $27, each holder of Bally
  Common Stock will receive an additional cash payment for each share of
  Bally Common Stock held by such holder, up to a maximum of $3 per share,
  equal to the excess of $27 over the Determination Price; and
 
    (ii) Each share of Bally PRIDES issued and outstanding immediately prior
  to the Effective Time of the Merger will be converted into the right to
  receive one share of Hilton PRIDES.
 
  In the event that the Determination Price is less than $20, Hilton shall
have the right, but not the obligation, to give written notice to Bally (the
"Top-Up Intent Notice") that the Board of Directors of Hilton has elected to
increase the Conversion Number such that the product of the Conversion Number
and the Determination Price equals $20. Such increase, however, will not
result in any increase or decrease in the amount of the Additional Cash
Payment which will, in such circumstances, equal $3 per share.
 
  Up to approximately 62,273,733 shares of Hilton Common Stock (after giving
effect to the Stock Split) may be issued to holders of outstanding shares of
Bally Common Stock pursuant to the Merger. This figure is calculated by taking
into account that as of August 15, 1996, there were (i) approximately 51.6
million shares of Bally Common Stock issued and outstanding; (ii) outstanding
stock options to purchase approximately 4.8 million shares of Bally Common
Stock; (iii) approximately 2.6 million shares of Bally Common Stock reserved
for issuance upon conversion of the 6% Convertible Subordinated Debentures due
1998 and the 10% Convertible Subordinated Debentures due 2006; (iv) the
Subsidiary Preferred Stock to be cancelled and converted into the right to
receive approximately 1.6 million shares of Bally Common Stock; and (v) 1.6
million shares of Bally Common Stock to be issued to Bally's Grand, Inc. in
connection with the acquisition by Bally of the land for the Paris Casino-
Resort in Las Vegas. In the event (i) that holders of Bally PRIDES convert
their shares into Bally Common Stock prior to the Merger, the number of Hilton
PRIDES issued in the Merger will decrease and the number of shares of Hilton
Common Stock issued in the Merger will increase based on a conversion ratio of
0.92 shares of Bally Common Stock for each share of Bally PRIDES, and (ii)
that Hilton gives the Top-Up Intent Notice, the Conversion Number will
increase as set forth in the foregoing paragraph.
 
TREATMENT OF STOCK OPTIONS
 
  At the Effective Time, each then outstanding option to purchase shares of
Bally Common Stock granted under a Bally stock option plan (as described in
the Merger Agreement), whether or not then exercisable, will
 
                                      47
<PAGE>
 
become immediately exercisable in full and will be settled in exchange for an
amount of cash per option share equal to (i) the product of the Conversion
Number and the Determination Price, plus (ii) the Additional Cash Payment (if
any), minus (iii) the exercise price per option share.
 
EXCHANGE PROCEDURES
 
  Promptly after the Effective Time, transmittal forms and instructions will
be mailed to each holder of record of certificates that, immediately prior to
the Effective Time, represented shares of Bally Common Stock or Bally PRIDES.
After receipt of such transmittal form, each holder of such certificates
should surrender the certificates to ChaseMellon Shareholder Services, L.L.C.
(the "Exchange Agent"), together with such letter of transmittal duly executed
and completed in accordance with the instructions thereto. In exchange
therefor, each such holder will be entitled to receive: (i) certificates of
Hilton Common Stock or Hilton PRIDES, as applicable, evidencing the whole
number of shares of Hilton Common Stock or Hilton PRIDES to which such holder
is entitled; (ii) in the case of holders of Bally Common Stock, the Additional
Cash Payment (if any), receivable upon consummation of the Merger; and (iii)
any dividends or other distributions to which such holder is entitled
(collectively, the "Merger Consideration"). If the certificate for shares of
Hilton Common Stock or Hilton PRIDES is to be issued in a name other than the
one in which the certificate for shares of the Bally Common Stock or Bally
PRIDES surrendered in exchange therefor is registered, documents evidencing
such transfer and establishing that applicable stock transfer taxes have been
paid or are not applicable must be presented to the Exchange Agent.
 
  After the Effective Time, no holder of a certificate which immediately prior
to the Effective Time represented shares of Bally Common Stock or Bally PRIDES
will be entitled to receive any dividend or other distribution from Hilton
until the holder surrenders the certificate for a certificate representing
shares of Hilton Common Stock or Hilton PRIDES. Upon such surrender, there
will be paid to the holder the amount of any dividends or other distributions
(without interest) which theretofore became payable with respect to the number
of whole shares of Hilton Common Stock or Hilton PRIDES. Until such surrender,
the certificates shall be deemed to evidence only the right to receive the
appropriate Merger Consideration.
 
  No fractional shares of Hilton Common Stock will be issued in the Merger. A
holder of Bally Common Stock who would otherwise be entitled to receive
fractional shares of Hilton Common Stock as a result of the Merger shall
receive cash in lieu thereof.
 
  Neither Hilton nor Bally will be liable to any holder of shares of Bally
Common Stock or Bally PRIDES for any shares of Hilton Common Stock, Hilton
PRIDES (or dividends or distributions with respect thereto), or Additional
Cash Payments which have been delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

the adoption of, and to take all other lawful action necessary to secure the
approval of its stockholders in regard to, the Merger and all other

to be issued in the Merger and to use all reasonable efforts to have the

for the purpose of approving and adopting the Merger Agreement; (iii) use its

<PAGE>
 
reasonable efforts to cause the shares of Hilton Common Stock and Hilton

  In addition, Bally has agreed, among other things, not to: (i) initiate,
solicit, or knowingly encourage the submission of any Acquisition Proposal (as
defined below); or (ii) enter into any agreement with respect to any such
Acquisition Proposal, or participate in discussions or negotiations regarding,
or furnish to any person any non-public information with respect to, or take
any other action to knowingly facilitate any inquiries or the making of any
proposal that constitutes or would reasonably be expected to lead to, an
Acquisition Proposal; provided, however, that, notwithstanding anything to the
contrary in the Merger Agreement: (A) Bally may participate in discussions or
negotiations with, and may furnish information concerning Bally and its
business, properties and assets to, a third party who, without any
solicitation by Bally or any of its representatives, seeks to engage in such
discussions or negotiations or requests such information, if (1) the Board of
Directors of Bally determines, based on the advice of Bally's outside legal
counsel, that failing to engage in such discussion or negotiations or provide
such information would reasonably be expected to violate the fiduciary duties
of the Board of Directors of Bally to its stockholders and (2) prior to
engaging in discussions or negotiations with, or furnishing information to,
such third party, Bally shall receive from such third party an executed
confidentiality agreement in reasonably customary form on terms no more
favorable to such person or entity than the terms contained in the
confidentiality agreement entered into by Hilton and Bally; and (B) the Board
of Directors of Bally may take and disclose to Bally's stockholders a position
with regard to a tender offer or exchange offer contemplated by Rules 14d-9
and 14e-2(a) promulgated under the Exchange Act and may make such disclosure
to the stockholders of Bally as may be required under applicable law;
provided, that the Board of Directors of Bally shall not recommend that the
stockholders of Bally tender their shares of Bally Common Stock unless such
recommendation constitutes a Permitted Action (as defined below).
 
  Notwithstanding anything to the contrary in the Merger Agreement, the Board
of Directors of Bally shall be permitted from time to time to take the
following actions in the circumstances described below: (i) to withdraw or
modify its approval or recommendation of the Merger Agreement or the Merger in
a manner adverse to Hilton; or (ii) to approve or recommend or enter into an
agreement with respect to an Acquisition Proposal; if, in each such case, (A)
an Acquisition Proposal is publicly proposed, publicly disclosed or
communicated to Bally and (B) the Board of Directors of Bally determines,
based on the advice of Bally's outside legal counsel, that such action is
required in order to comply with its fiduciary duties to the stockholders of
Bally. No action by the Board of Directors of Bally permitted by the preceding
sentence (each, a "Permitted Action") shall constitute a breach of the Merger
Agreement by Bally.
 
  "Acquisition Proposal" is defined in the Merger Agreement to include any
proposal or offer from any person relating to: (i) any direct or indirect
acquisition or purchase of more than 20% of either the capital stock of Bally
or the consolidated assets of Bally and its subsidiaries taken as a whole;
(ii) any tender offer or exchange offer that if consummated would result in
any person beneficially owning 20% or more of the capital stock of Bally; or
(iii) any merger, consolidation or business combination, involving Bally other
than the transactions contemplated by the Agreement; provided, however, that
any acquisition of shares of capital stock of Bally by Hilton and its
subsidiaries described in clause (i) shall not constitute an Acquisition
Proposal.
 
INDEMNIFICATION
 
  Until the Effective Time Bally shall, and from and after the Effective Time,
Hilton shall, indemnify, defend, and hold harmless any officer or director of
Bally or any subsidiary of Bally (each an "Indemnified Party") against all
losses, claims, damages, costs, expenses (including reasonable attorneys' fees
and expenses), liabilities or judgments or amounts that are paid in settlement
of or in connection with any action based in whole or substantially on, or
arising in whole or substantially out of the fact that such a person is or was
an officer or
 
                                      51
<PAGE>
 
director of Bally or any subsidiary of Bally, pertaining to any matter
existing or occurring on or prior to the Effective Time (including, without
limitation, the transactions contemplated in the Merger Agreement), whether
asserted or claimed prior to, or on or after, the Effective Time. In each such
case indemnification shall be to the full extent a corporation is permitted
under the DGCL to indemnify its own directors and officers. Bally or Hilton,
as the case may be, will pay expenses in advance of the final disposition of
any such action or proceeding to each Indemnified Party to the fullest extent
permitted by law.
 
  After the Effective Time, Hilton shall maintain, and shall cause its
subsidiaries to maintain, for a period of at least six (6) years from the
Effective Time, among other things: (i) all rights to indemnification and
exculpation now existing in their respective Certificates of Incorporation and
Bylaws; (ii) the current policies of directors and officers liability
insurance maintained by Bally (or to provide at least the same amounts and
coverage and to maintain conditions which are no less advantageous in any
material respect to the Indemnified Parties), with respect to matters arising
before the Effective Time; provided, however, that Hilton shall not be
required to pay an annual premium for such insurance in excess of 150% of the
last annual premium paid by Bally.
 
TERMINATION
 
  The Merger Agreement may be terminated at any time prior to the Effective
Time: (a) by mutual written consent of Bally and Hilton; (b) by either Bally
or Hilton, if any of the conditions precedent to its consummation of the
Merger Agreement shall have become incapable of fulfillment and shall not have
been waived (other than as a result of its breach); (c) by either Bally or
Hilton if the Merger shall not have been consummated on or before the earlier
of (i) the 90th day following the mailing of this Joint Proxy
Statement/Prospectus and (ii) March 31, 1997 (other than as a result of its
breach); (d) by Bally, if the Determination Price is less than $20 (after
giving effect to the Stock Split) and Hilton shall not have given the Top-Up
Intent Notice to Bally at or before 2:00 p.m. on the second business day prior
to the Closing Date; (e) by Hilton, if the Board of Directors of Bally shall
have taken any Permitted Action; and (f) by Bally if (i) the Board of
Directors of Bally withdraws or modifies its approval of the recommendation of
the Merger Agreement as permitted by the terms of the Merger Agreement or (ii)
Bally enters into a definitive agreement providing for the implementation of
an Acquisition Proposal, in accordance with the provisions of the Merger
Agreement. If an Acquisition Proposal is publicly commenced, proposed or
disclosed and the Merger Agreement is terminated (i) pursuant to clause (e) or
(f) of the immediately preceding sentence, or (ii) pursuant to clause (b) of
the preceding sentence due to rejection of the Bally Merger Proposal by the
Bally stockholders, Bally shall pay Hilton a topping fee of $50,000,000 and
certain of its related expenses (not to exceed $5,000,000) in the event that
an Acquisition Proposal is consummated or Bally enters into an agreement with
respect thereto within one (1) year following the termination of the Merger
Agreement.
 
AMENDMENT AND MODIFICATION
 
  Subject to applicable law, the Merger Agreement may be amended, modified or
supplemented only by written agreement of Hilton and Bally at any time prior
to the Effective Time with respect to any of the terms contained therein;
provided, that after the Merger Agreement is adopted by Bally stockholders, no
such amendment or modification may reduce the amount or change the form of the
Merger Consideration.
 
FEES AND EXPENSES
 
  The Merger Agreement provides that, except as provided under "Termination"
above, each party thereto shall pay all costs and expenses incurred by it in
connection with the Merger Agreement and the consummation of the transactions
contemplated thereby.

                                                                    $3,187.1
                                                                    ========
</TABLE>
 
 (1) There are no significant adjustments required to the historical financial
     data of Bally to conform to the accounting policies of Hilton. Certain
     reclassifications have been made to the historical amounts of Bally to
     conform the financial presentation of the two companies. Specifically,
     selling, general and administrative expenses and depreciation and
     amortization have been reclassified to other costs and expenses, and
     interest income has been reclassified from other revenue to interest and
     dividend income. Other reclassifications made to conform the financial
     presentation are not material to the unaudited pro forma condensed
     financial statements.
 (2) Historical income from continuing operations per share of Hilton is
     presented after giving effect to the Stock Split. Pro forma income from
     continuing operations per share is computed on the basis of the combined
     weighted average number of shares of Hilton Common Stock and Hilton
     Common Stock equivalents after giving effect to the Stock Split and the
     issuance of shares to consummate the Merger.
 (3) To record certain estimated operational efficiencies derived from the
     historical cost of those items which are expected to be eliminated or
     reduced as a result of the Merger. The elimination of duplicative
     corporate office and operational support functions is estimated to reduce
     other costs and expenses and corporate expense by $11.5 million and $7.8
     million, respectively, for the six months ended June 30, 1996, and to
     reduce other costs and expenses and corporate expense by $22.3 million
     and $13.9 million, respectively, for the year ended December 31, 1995.
 (4) To adjust depreciation expense due to the revaluation of acquired
     property and equipment and adjust goodwill amortization resulting from
     the allocation of the purchase price of Bally. Depreciation expense is
     reduced $8.2 million for the six months ended June 30, 1996 and $9.3
     million for the year ended December 31, 1995. Goodwill amortization is
     increased $14.0 million for the six months ended June 30, 1996 and $28.4
     million for the year ended December 31, 1995. Goodwill is amortized over
     40 years.
 (5) Pro forma results and financial position are adjusted by an assumed
     refinancing of Bally debt as follows:
   (i) Bally debt is adjusted to estimated fair market value;
   (ii) Reduction of Bally debt totaling $150.0 million assumed to have been
        paid with excess Hilton and Bally cash balances based on estimates of
        available cash reserves throughout the periods; and
 
                                      57
<PAGE>
 
     (iii) Refinancing the balance of Bally debt with available Hilton debt
           capacity at an average floating rate of 5.89% for the six months
           ended June 30, 1996 and 6.42% for the year ended December 31, 1995.
           Each 1/8 percent change in the floating rate on this refinancing
           would result in a change in interest expense of $.7 million for the
           six months ended June 30, 1996 and $1.5 million for the year ended
           December 31, 1995.
     The refinancing decreases interest expense by $31.9 million for the six
     months ended June 30, 1996 and $57.0 million for the year ended December
     31, 1995 due to lower outstanding debt balances and lower interest rates.
     Lower cash balances available for investment result in a reduction of
     interest income of $4.4 million for the six months ended June 30, 1996 and
     $9.6 million for the year ended December 31, 1995.
 (6) Interest expense is reduced $.4 million for the six months ended June 30,
     1996 and $1.1 million for the year ended December 31, 1995 due to the
     conversion of Bally's 8% Convertible Senior Subordinated Debentures due
     2000.
 (7) To record the tax effect of pro forma adjustments to depreciation
     expense, interest income, interest expense and cost reductions associated
     with estimated operational efficiencies. The amortization of goodwill is
     not deductible for tax purposes.
 (8) Adjustment to minority interest is attributable to the following:
      (i) The cancellation and conversion of the Series A Cumulative
          Exchangeable Preferred Stock of Bally's Casino, Inc. (the "Subsidiary
          Preferred Stock") into the right to receive shares of Bally Common
          Stock in connection with the merger of Bally's Casino, Inc. with and
          into Bally, and
     (ii) The impact of the Bally debt refinancing.
 (9) To increase Bally's property and equipment to estimated fair market
     value.
(10) To reflect the excess purchase price over fair value of net tangible
     assets acquired and liabilities assumed.
(11) The reduction in other assets reflects (i) deferred financing costs of
     Bally not valued due to the adjustment of debt to estimated fair market
     value and (ii) the forgiveness of a tax-sharing receivable of Bally
     pursuant to the Merger Agreement.
(12) The net increase in current liabilities reflects (i) the accrual of
     severance and direct merger costs of Hilton and Bally and (ii) a
     reduction of the current portion of long-term debt as part of the Bally
     debt refinancing.
(13) To record the deferred tax effect of the pro forma balance sheet
     adjustments, primarily related to property and equipment and estimated
     severance costs.
(14) The net increase in stockholders' equity results from the following:

                      DESCRIPTION OF HILTON CAPITAL STOCK
 
  As of August 15, 1996, Hilton was authorized to issue 90,000,000 shares of
Hilton Common Stock, of which 51,024,707 shares were issued, including
treasury shares of 2,170,256, and 10,000,000 shares of Hilton Preferred Stock,
of which no shares have been issued. Assuming approval of the amendments to
Hilton's Certificate of Incorporation proposed for consideration at the Hilton
Special Meeting, the authorized capital stock of Hilton will consist of
400,000,000 shares of Hilton Common Stock and 24,832,700 shares of Hilton
Preferred Stock, of which 14,832,700 shares will be designated as Hilton
PRIDES.
 
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 the Hilton Board out of funds legally available therefor. Hilton
has paid cash dividends on its Common Stock. Any further determination to pay
cash dividends will be at the discretion of the Board of Directors of Hilton
and will depend upon the earnings of Hilton, its financial condition, capital
requirements and other factors as the Board of Directors of Hilton may deem
relevant. The Hilton Common Stock is not convertible and has no preemptive
rights. There are no redemption provisions with respect to the Hilton Common
Stock.
 
  For a description of redemption or forced sale for regulatory reasons
applicable to the Hilton Common Stock, see "Description of the Hilton PRIDES--
Redemption or Forced Sale for Regulatory Reasons."
 
PREFERRED STOCK
 
  Hilton's Certificate of Incorporation provides that Hilton Preferred Stock
may be issued from time to time in one or more series. The Board of Directors
of Hilton has authority to fix or alter the dividend rights, dividend rates,
conversion rights, voting rights and terms of redemption (including sinking
fund provisions), redemption prices and liquidation preferences of any wholly
unissued series of Hilton Preferred Stock, as well as the number of shares
constituting any such unissued series and the designation thereof, and to
increase or decrease the number of shares of any outstanding series (but not
below the number of shares of such series then outstanding), without any
further vote or action by Hilton's stockholders.
 
PREFERRED SHARE PURCHASE RIGHTS
 
  On July 14, 1988, Hilton adopted a Preferred Share Purchase Rights Plan
("Rights Plan") and declared a dividend distribution of one Preferred Share
Purchase Right (collectively, the "Rights") on each outstanding share of
Hilton Common Stock. The Rights are transferrable only with Hilton Common
Stock until they become exercisable.
 
  Generally, the Rights become exercisable only if a person or group (other
than the Hilton Interests, as hereafter defined) acquires 20% or more of the
issued and outstanding shares of Hilton Common Stock or announces a tender
offer, the consummation of which would result in ownership by a person or
group of 20% or more of the issued and outstanding shares of Hilton Common
Stock. Each Right entitles stockholders to buy one one-hundredth of a share of
a new series of junior participating preferred stock at an exercise price of
$150, designated Series A Junior Participating Preferred Stock, par value $.01
per share, of Hilton (the "Hilton Series A Preferred Stock").
 
  If Hilton is acquired in a merger or other business combination transaction,
each Right entitles its holder to purchase, at the Right's then current price,
a number of the acquiring company's common shares having a then current market
value of twice the Right's exercise price. In addition, if a person or group
(other than the Hilton Interests) acquires 30% or more of the issued and
outstanding shares of Hilton Common Stock, otherwise than
 
                                      59
<PAGE>
 
pursuant to a cash tender offer for all shares in which such person or group
increases its stake from below 20% to 80% or more of the issued and
outstanding shares of Hilton Common Stock, each Right entitles its holder
(other than such person or members of such group) to purchase, at the Right's
then current exercise price, shares of the Hilton Common Stock having a market
value of twice the Right's exercise price.
 
  Following the acquisition by a person or group of beneficial ownership of
50% or more of the Hilton Common Stock and prior to an acquisition of 50% or
more of the Hilton Common Stock, Hilton's Board of Directors may exchange the
Rights (other than Rights owned by such person or group), in whole or in part,
at an exchange ratio of one share of Hilton Common Stock (or one one-hundredth
of a share of the new series of junior participating preferred stock) per
Right.
 
  Prior to the acquisition by a person or group of beneficial ownership of 20%
or more of the Hilton Common Stock, the Rights are redeemable for one cent per
Right at the option of Hilton's Board of Directors.
 
  "Hilton Interests" refer to Barron Hilton and the Conrad N. Hilton Fund and
the shares of Hilton Common Stock beneficially owned by them.
 
DELAWARE GENERAL CORPORATION LAW SECTION 203
 
  As a corporation organized under the laws of the State of Delaware, Hilton
is subject to Section 203 of the Delaware General Corporation Law, which
restricts certain business combinations between Hilton and an "interested
stockholder" (in general, a stockholder owning 15% or more of the outstanding
voting stock of Hilton) or such stockholder's affiliates or associates for a
period of three years following the date on which the stockholder becomes an
"interested stockholder." The restrictions do not apply if: (i) prior to an
interested stockholder becoming such, the Hilton Board approves either the
business combination or the transaction in which the stockholder becomes an
interested stockholder; (ii) upon consummation of the transaction in which
such stockholder becomes an interested stockholder, such interested
stockholder owns at least 85% of the voting stock of Hilton outstanding at the
time the transaction commenced (excluding shares owned by certain employee
stock ownership plans and persons who are both directors and officers of
Hilton); or (iii) on or subsequent to the date an interested stockholder
becomes such, the business combination is both approved by the Hilton Board
and authorized at an annual or special meeting of Hilton's stockholders (and
not by written consent) by the affirmative vote of at least 66 2/3% of the
outstanding voting stock of Hilton not owned by the interested stockholder.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
  Upon consummation of the Merger and the transactions contemplated thereby,
it is estimated there will be approximately 140,000,000 shares of Hilton
Common Stock authorized but unissued (assuming the issuance of approximately
62,273,733 shares of Hilton Common Stock in the Merger), and 10,000,000 shares
of Hilton Preferred Stock authorized but unissued, for future issuance without
additional stockholder approval. These additional shares may be utilized for a
variety of corporate purposes, including future offerings to raise additional
capital or to facilitate corporate acquisitions.
 
  The issuance of the Hilton PRIDES could have the effect of delaying or
preventing a change in control of Hilton. The issuance of the Hilton PRIDES
could decrease the amount of earnings and assets available for distribution to
the holders of Hilton Common Stock or could adversely affect the rights and
powers, including voting rights, of the holders of the Hilton Common Stock. In
certain circumstances, such issuance could have the effect of decreasing the
market price of the Hilton Common Stock.
 
  One of the effects of the existence of unissued Hilton Common Stock or
Hilton Preferred Stock may be to enable the Hilton Board to issue shares to
persons friendly to current management which could render more difficult or
discourage an attempt to obtain control of Hilton by means of a merger, tender
offer, proxy contest or otherwise, and thereby protect the continuity of
management. Such additional shares also could be used to dilute the stock
ownership of persons seeking to obtain control of Hilton.
 
                                      60

  Hilton does not currently have any plans to issue additional shares of
Hilton Common Stock or Hilton Preferred Stock other than the shares of Hilton
Common Stock and Hilton PRIDES which may be issued pursuant to the Merger.
 
REGISTRAR AND TRANSFER AGENT
 
  The registrar and transfer agent for the Hilton Common Stock and Hilton
PRIDES will be ChaseMellon Shareholder Services, L.L.C.
 
                       DESCRIPTION OF THE HILTON PRIDES
 
  The summary contained herein of the terms of shares of Hilton PRIDES does
not purport to be complete and is subject to and qualified in its entirety by
reference to all of the provisions of Hilton's proposed amendment to its
Certificate of Incorporation and the Certificate of Designations, Preferences,
Rights and Limitations (the "Certificate of Designations") relating to the
shares of Hilton PRIDES, copies of which have been filed as exhibits to the
Registration Statement of which this Joint Proxy Statement/Prospectus is a
part.
 
  Hilton's Board of Directors has authorized the issuance of up to 14,832,700
shares of Hilton PRIDES with a stated liquidation value of $11.125 per share.
 
DIVIDENDS
 
  Holders of shares of Hilton PRIDES will be entitled to receive, when, as and
if declared by the Hilton Board out of funds legally available therefor, cash
dividends from the date of initial issuance of the shares of Hilton PRIDES at
the rate per annum of 8% of the stated liquidation value per share (equivalent
to $.89 per annum, or $.2225 per quarter, for each share of Hilton PRIDES),
payable quarterly in arrears on each January 3, April 3, July 3 and October 3,
or, if any such date is not a business day, on the next succeeding business
day commencing (subject to the provisions of the immediately following
sentence) on the next such date following consummation of the Merger. All
accumulated and unpaid dividends on the Bally PRIDES as of the Effective Time
shall become accumulated dividends on the Hilton PRIDES exchanged therefor,
payable on the next dividend payment date following the Merger (and such
dividends shall not be payable with respect to Bally PRIDES); provided,
however, that in the event the Merger occurs on or after the record date for a
dividend on the Bally PRIDES but prior to the payment date for such dividend,
then such dividend shall be payable with respect to the Bally PRIDES (and
shall not constitute an accumulated dividend on the Hilton PRIDES), and
dividends shall commence accruing on the Hilton PRIDES as of the payment date
for such dividend (payable on the next succeeding payment date).
 
  With respect to any dividend period during which a redemption occurs, Hilton
may, at its option, declare accrued dividends to, and pay such dividends on,
the date fixed for redemption, in which case such dividends will be payable in
cash to the holders of shares of Hilton PRIDES as of the record date for such
dividend payment and would not be included in the calculation of the related
Hilton PRIDES Call Price as set forth below. The first dividend period will be
from the date of initial issuance of the shares of Hilton PRIDES to but
excluding the payment date next following the consummation of the Merger, and
the first dividend will be payable on the payment date next following the
consummation of the Merger. Dividends will cease to accrue in respect of the
shares of Hilton PRIDES on the Mandatory Conversion Date (as hereinafter
defined) or on the date of their earlier conversion or redemption.
 
  Dividends will be payable to holders of record as they appear on the stock
register of Hilton on such record dates, not less than 15 nor more than 60
days preceding the payment date thereof, as shall be fixed by the Hilton
Board. Dividends payable on shares of Hilton PRIDES for any period less than a
full quarterly dividend period will be computed on the basis of a 360-day year
of twelve 30-day months and the actual number of days elapsed in any period
less than one month.
 
                                      61
<PAGE>
 
  Dividends on shares of Hilton PRIDES will accrue whether or not there are
funds legally available for the payment of such dividends and whether or not
such dividends are declared. Accrued but unpaid dividends on shares of Hilton
PRIDES will cumulate as of the dividend payment date on which they first
become payable, but no interest will accrue on accumulated but unpaid
dividends on shares of Hilton PRIDES.
 
  The shares of Hilton PRIDES will rank on a parity as to payment of dividends
with any future preferred stock issued by Hilton that by its terms ranks pari
passu with the shares of Hilton PRIDES ("Parity Preferred Stock").
 
  As long as any shares of Hilton PRIDES are outstanding, no dividends (other
than dividends payable in shares of, or warrants, rights or options
exercisable for or convertible into shares of, Hilton Common Stock or any
other capital stock of Hilton ranking junior to Hilton PRIDES as to the
payment of dividends or the distribution of assets upon liquidation ("Junior
Stock") and cash in lieu of fractional shares in connection with any such
dividend) will be paid or declared in cash or otherwise, nor will any other
distribution be made (other than a distribution payable in Junior Stock and
cash in lieu of fractional shares in connection with any such distribution) on
any Junior Stock unless: (i) full dividends on Preferred Stock (including the
shares of Hilton PRIDES) that does not constitute Junior Stock ("Senior
Preferred Stock") have been paid, or declared and set aside for payment, for
all dividend periods terminating at or before the date of such Junior Stock
dividend or distribution payment to the extent such dividends are cumulative;
(ii) dividends in full for the current quarterly dividend period have been
paid, or declared and set aside for payment, on all Senior Preferred Stock to
the extent such dividends are cumulative; (iii) Hilton has paid or set aside
all amounts, if any, then or theretofore required to be paid or set aside for
all purchase, retirement, and sinking funds, if any, for any Senior Preferred
Stock; and (iv) Hilton is not in default on any of its obligations to redeem
any Senior Preferred Stock.
 
  In addition, as long as any shares of Hilton PRIDES are outstanding, no
shares of any Junior Stock may be purchased, redeemed, or otherwise acquired
by Hilton or any of its subsidiaries (except in connection with a
reclassification or exchange of any Junior Stock through the issuance of other
Junior Stock (and cash in lieu of fractional shares in connection therewith)
or the purchase, redemption or other acquisition of any Junior Stock with any
Junior Stock (and cash in lieu of fractional shares in connection therewith))
nor may any funds be set aside or made available for any sinking fund for the
purchase or redemption of any Junior Stock unless: (i) full dividends on
Senior Preferred Stock have been paid, or declared and set aside for payment,
for all dividend periods terminating at or before the date of such purchase or
redemption to the extent such dividends are cumulative; (ii) dividends in full
for the current quarterly dividend period have been paid, or declared and set
aside for payment, on all Senior Preferred Stock to the extent such dividends
are cumulative; (iii) Hilton has paid or set aside all amounts, if any, then
or theretofore required to be paid or set aside for all purchase, retirement,
and sinking funds, if any, for any Senior Preferred Stock; and (iv) Hilton is
not in default on any of its obligations to redeem any Senior Preferred Stock.
 
  Subject to the provisions described above, such dividends or other
distributions (payable in cash, property, or Junior Stock) as may be
determined by the Hilton Board may be declared and paid on the shares of any
Junior Stock from time to time and Junior Stock may be purchased, redeemed or
otherwise acquired by Hilton or any of its subsidiaries from time to time. In
the event of the declaration and payment of any such dividends or other
distributions, the holders of such Junior Stock will be entitled, to the
exclusion of holders of any Senior Preferred Stock, to share therein according
to their respective interests.
 
  As long as any shares of Hilton PRIDES are outstanding, dividends or other
distributions may not be declared or paid on any Parity Preferred Stock (other
than dividends or other distributions payable in Junior Stock and cash in lieu
of fractional shares in connection therewith), and Hilton may not purchase,
redeem or otherwise acquire any Parity Preferred Stock (except with any Junior
Stock and cash in lieu of fractional shares in connection therewith), unless:
either (a)(i) full dividends on Senior Preferred Stock have been paid, or
declared and set aside for payment, for all dividend periods terminating at or
before the date of such Parity Preferred Stock dividend, distribution,
purchase, redemption or other acquisition payment to the extent such dividends
are cumulative; (ii) dividends in full for the current quarterly dividend
period have been paid, or declared and set
 
                                      62
<PAGE>
 
aside for payment, on all Senior Preferred Stock to the extent such dividends
are cumulative; (iii) Hilton has paid or set aside all amounts, if any, then
or theretofore required to be paid or set aside for all purchase, retirement,
and sinking funds, if any, for any Senior Preferred Stock; and (iv) Hilton is
not in default on any of its obligations to redeem any Senior Preferred Stock;
or (b) with respect to the payment of dividends only, any such dividends will
be declared and paid pro rata so that the amounts of any dividends declared
and paid per share of Hilton PRIDES and each other share of Senior Preferred
Stock will in all cases bear to each other the same ratio that accrued
dividends (including any accumulation with respect to unpaid dividends for
prior dividend periods, if such dividends are cumulative) per share of Hilton
PRIDES and such other shares of Senior Preferred Stock bear to each other.
 
MANDATORY CONVERSION OF PRIDES
 
  On October 3, 1999 (the "Mandatory Conversion Date"), each outstanding share
of Hilton PRIDES will, unless previously either redeemed or converted at the
option of the holder into Hilton Common Stock, as hereinafter described,
mandatorily convert into (i) shares of Hilton Common Stock at the Common
Equivalent Rate (as defined below) in effect on such date and (ii) the right
to receive cash in an amount equal to all accrued and unpaid dividends on such
shares of Hilton PRIDES (other than previously declared dividends payable to a
holder of record as of a prior date) to the Mandatory Conversion Date, whether
or not declared, out of funds legally available for the payment of dividends,
subject to the right of Hilton to redeem the shares of Hilton PRIDES on or
after October 3, 1998, and before the Mandatory Conversion Date, as described
below, and subject to the conversion of the shares of Hilton PRIDES at the
option of the holder at any time before the Mandatory Conversion Date, as
described below. The "Common Equivalent Rate" is initially 1.12 shares of
Hilton Common Stock for each share of Hilton PRIDES, after giving effect to
the Stock Split, and is subject to adjustment as described below. Dividends
will cease to accrue on the Mandatory Conversion Date in respect of the shares
of Hilton PRIDES then outstanding. If an Additional Cash Payment is made in
connection with the Merger, at conversion a holder of Hilton PRIDES will
receive a cash payment in an amount equal to the Additional Cash Payment such
holder would have received if such conversion had occurred immediately prior
to the Effective Time.
 
  Because the price of the Hilton Common Stock is subject to market
fluctuations, the value of the Hilton Common Stock that may be received by
holders of shares of Hilton PRIDES upon their mandatory conversion may be more
or less than the current market value of the Bally PRIDES being exchanged for
Hilton PRIDES in the Merger.
 
OPTIONAL REDEMPTION
 
  Shares of Hilton PRIDES are not redeemable by Hilton before October 3, 1998
(the "Initial Redemption Date"). At any time and from time to time on or after
the Initial Redemption Date until immediately before the Mandatory Conversion
Date, Hilton will have the right to redeem, in whole or in part, the
outstanding shares of Hilton PRIDES. Upon any such redemption, Hilton will
deliver to the holder thereof in exchange for each share of Hilton PRIDES
subject to redemption the greater of: (i) the number of shares of Hilton
Common Stock equal to the applicable Call Price (as defined below) in effect
on the redemption date divided by the Current Market Price (as defined below)
of the Hilton Common Stock, determined as of the second Trading Day
immediately preceding the Notice Date (as defined below); or (ii) 0.92 of one
share of Hilton Common Stock (the "Minimum Redemption Rate", which is subject
to adjustment in the manner described below), after giving effect to the Stock
Split. Dividends will cease to accrue on the shares of Hilton PRIDES on the
date fixed for their redemption. If an Additional Cash Payment is made in
connection with the Merger, at redemption a holder of Hilton PRIDES will
receive a cash payment in an amount equal to the Additional Cash Payment such
holder would have received if such redemption had occurred immediately prior
to the Effective Time.
 
  The Call Price of each share of Hilton PRIDES is the sum of: (i) $11.348 on
and after the Initial Redemption Date to and including January 2, 1999;
$11.292 on and after January 3, 1999, to and including April 2, 1999;
 
                                      63
<PAGE>
 
$11.237 on and after April 3, 1999, to and including July 2, 1999; $11.181 on
and after July 3, 1999, to and including September 2, 1999; and $11.125 (the
stated liquidation value of one share of Hilton PRIDES) on and after September
3, 1999, to and including October 3, 1999; and (ii) all accrued and unpaid
dividends thereon to but not including the date fixed for redemption (other
than previously declared dividends payable to a holder of record as of a prior
date).
 
  The "Current Market Price" per share of the Hilton Common Stock on any date
of determination means the lesser of (x) the average of the closing sale
prices of the Hilton Common Stock for the 15 consecutive Trading Days ending
on and including such date of determination and (y) the closing sale price of
the Hilton Common Stock for such date of determination; provided, however,
that, with respect to any redemption of shares of Hilton PRIDES, if any event
resulting in an adjustment of the Common Equivalent Rate occurs during the
period beginning on the first day of such 15-day period and ending on the
applicable Redemption Date, the Current Market Price as determined pursuant to
the foregoing will be appropriately adjusted to reflect the occurrence of such
event. The "Notice Date" with respect to any notice given by Hilton in
connection with a redemption of the shares of Hilton PRIDES means the earlier
of the date of the public announcement of such redemption and the date of the
commencement of mailing of such notice to the holders of shares of Hilton
PRIDES. Closing sale prices shall be based on the last sale price or the
average of the closing bid and ask prices on the NYSE or, if not listed
thereon, the Nasdaq National Market or the over the counter market, as
appropriate.
 
  If fewer than all the outstanding shares of Hilton PRIDES are to be called
for redemption, the shares of Hilton PRIDES to be called will be selected by
Hilton from outstanding shares of Hilton PRIDES not previously called by lot
or pro rata (as nearly as may be) or by any other method determined by the
Board of Directors in its sole discretion to be equitable.
 
  Hilton will provide notice of any redemption of shares of Hilton PRIDES to
holders of record of the shares of Hilton PRIDES to be called for redemption
not less than 30 nor more than 60 days before the date fixed for redemption.
Any such notice will be provided by mail, sent to the holders of record of the
shares of Hilton PRIDES to be called at each such holder's address as it
appears on the stock register of Hilton, first class postage prepaid;
provided, however, that failure to give such notice or any defect therein will
not affect the validity of the proceeding for redemption of any shares of
Hilton PRIDES to be redeemed except as to the holder to whom Hilton has failed
to give such notice or whose notice was defective. On and after the redemption
date, all rights of the holders of the shares of Hilton PRIDES called for
redemption will terminate except the right to receive the redemption price and
to receive dividends on such shares previously declared and payable to the
holders of record of such shares as of a prior date (unless Hilton defaults on
the payment of the redemption price). A public announcement of any call for
redemption will be made by Hilton before, or at the time of, the mailing of
such notice of redemption.
 
  Each holder of shares of Hilton PRIDES called for redemption must surrender
the certificates evidencing such shares of Hilton PRIDES to Hilton at the
place designated in the notice of redemption and will thereupon be entitled to
receive certificates for shares of Hilton Common Stock and cash for any
fractional share amount.
 
REDEMPTION OR FORCED SALE FOR REGULATORY REASONS
 
  If the Nevada Gaming Commission (the "Nevada Commission"), the Mississippi
Gaming Commission (the "Mississippi Commission"), the New Jersey Casino
Control Commission (the "New Jersey Commission") or the Louisiana Gaming
Control Board (the "Louisiana Board," and together with the Nevada Commission,
the New Jersey Commission and the Mississippi Commission, the "Gaming
Commissions") find that a holder or beneficial owner of shares of Hilton
PRIDES or Hilton Common Stock must be licensed or qualified or found suitable
to hold or own the shares of Hilton PRIDES or Hilton Common Stock under the
Nevada Gaming Control Act and regulations promulgated thereunder
(collectively, the "Nevada Act"), the Mississippi Gaming Control Act and
regulations promulgated thereunder (collectively, the "Mississippi Act"), the
New Jersey Casino Control Act and regulations promulgated thereunder
(collectively, the "New Jersey Act") or the Louisiana Riverboat Economic
Development and Gaming Control Act (the "Louisiana Act," and together with the
Nevada
 
                                      64
<PAGE>
 
Act, the Mississippi Act and the New Jersey Act, the "Gaming Acts"), and if
such holder or such beneficial owner is not found qualified, licensed or
suitable within any time period specified by the Gaming Acts, Hilton has the
right, at its option: (i) to require such holder or beneficial owner to
dispose of all or a portion of such holder's or beneficial owner's shares of
Hilton PRIDES or Hilton Common Stock within 120 days after receipt of notice
by such holder or beneficial owner of its disqualification under such Gaming
Act (the "Notice Date") (or such different period as may be prescribed by the
respective Gaming Commission); or (ii) to redeem shares of Hilton PRIDES or
Hilton Common Stock held by such holder, by action of the Hilton Board if in
the judgment of the Hilton Board such action should be taken pursuant to
Section 151(b) of the DGCL or any other applicable provision of law, to the
extent necessary to prevent the loss or secure the reinstatement of any
government-issued license or franchise held by Hilton or any subsidiary to
conduct any portion of the business of Hilton or any subsidiary, which license
or franchise is conditioned upon some or all of the holders of Hilton's
securities possessing prescribed qualifications. Such unsuitable or
disqualified holder is required to indemnify Hilton for any and all direct or
indirect costs, including attorneys' fees, incurred by Hilton as a result of
such holder's continuing ownership or failure to divest promptly.
 
  The redemption price of shares of Hilton PRIDES or Hilton Common Stock to be
redeemed would be equal to the lesser of (i) the holder's original purchase
price for the security or (ii) the lowest closing sale price of such security
between the Notice Date and the date 120 days after the Notice Date.
 
  Commencing on the date a Gaming Commission serves notice upon Hilton of the
determination of unsuitability or disqualification, it is unlawful under the
respective Gaming Act for the unsuitable or disqualified holder: to (i)
receive any dividends upon shares of Hilton PRIDES or Hilton Common Stock, or
any distribution of any kind other than in connection with the repurchase of
such securities; (ii) exercise, directly or through any trustee or nominee,
any voting right conferred by shares of Hilton PRIDES or Hilton Common Stock;
or (iii) receive any remuneration in any form from Hilton for services
rendered or otherwise.
 
CONVERSION AT THE OPTION OF THE HOLDER
 
  The shares of Hilton PRIDES are convertible, in whole or in part, at the
option of the holder thereof, at any time before the Mandatory Conversion
Date, unless previously redeemed, into shares of Hilton Common Stock at a rate
of 0.92 of a share of Hilton Common Stock, after giving effect to the Stock
Split, subject to adjustment in certain events, for each share of Hilton
PRIDES (the "Optional Conversion Rate"), equivalent to a conversion price of
$12.092 per share of Hilton Common Stock (the "Conversion Price"), subject to
adjustment as described below. The right to convert shares of Hilton PRIDES
called for redemption will terminate immediately before the close of business
on any redemption date with respect to such shares. If an Additional Cash
Payment is made in connection with the Merger, at conversion a holder of
Hilton PRIDES will receive a cash payment in an amount equal to the Additional
Cash Payment such holder would have received if such conversion had occurred
immediately prior to the Effective Time for an equivalent number of shares of
Bally Common Stock.
 
  Conversion of shares of Hilton PRIDES at the option of the holder may be
effected by delivering certificates evidencing such shares of Hilton PRIDES,
together with written notice of conversion and a proper assignment of such
certificates to Hilton or in blank (and, if applicable, cash payment of an
amount equal to the dividend attributable to the current quarterly dividend
period payable on such shares), to the office of the transfer agent for Hilton
PRIDES or to any other office or agency maintained by Hilton for that purpose
and otherwise in accordance with conversion procedures established by Hilton.
Each optional conversion will be deemed to have been effected immediately
before the close of business on the date on which the foregoing requirements
have been satisfied. The conversion will be at the Optional Conversion Rate in
effect at such time and on such date.
 
  Holders of shares of Hilton PRIDES at the close of business on a record date
for any payment of declared dividends will be entitled to receive the dividend
payable on such shares of Hilton PRIDES on the corresponding dividend payment
date notwithstanding the optional conversion of such shares of Hilton PRIDES
following such
 
                                      65
<PAGE>
 
record date and before such dividend payment date. However, shares of Hilton
PRIDES surrendered for conversion after the close of business on a record date
for any payment of declared dividends and before the opening of business on
the next succeeding dividend payment date must be accompanied by payment in
cash of an amount equal to the dividend attributable to the current quarterly
dividend payable on such date (unless such shares of Hilton PRIDES are subject
to redemption on a redemption date on or after such record date and on or
prior to such dividend payment date). A holder of shares of Hilton PRIDES
called for redemption on or after the record date for any dividend payment and
on or prior to the payment date for such dividend will receive the dividend on
such shares of Hilton PRIDES payable on that dividend payment date and will be
able to convert such shares of Hilton PRIDES after the record date for such
dividend without paying an amount equal to such dividend to Hilton upon
conversion. Except as provided above, upon any optional conversion of shares
of Hilton PRIDES, Hilton will make no payment of or allowance for unpaid
dividends, whether or not in arrears, on such shares of Hilton PRIDES, or for
previously declared dividends or distributions on the shares of Hilton Common
Stock issued upon such conversion.
 
CONVERSION ADJUSTMENTS
 
  The Common Equivalent Rate, the Minimum Redemption Rate and the Optional
Conversion Rate are each subject to adjustment as appropriate in certain
circumstances, including if Hilton: (i) pays a stock dividend or makes a
distribution with respect to its Hilton Common Stock in shares of Hilton
Common Stock; (ii) subdivides or splits its outstanding Hilton Common Stock;
(iii) combines its outstanding Hilton Common Stock into a smaller number of
shares; (iv) issues by reclassification of its shares of Hilton Common Stock
any shares of Hilton Common Stock; (v) issues certain rights or warrants to
all holders of its Hilton Common Stock; or (vi) pays a dividend or distributes
to all holders of its Hilton Common Stock evidences of its indebtedness, cash
or other assets (including capital stock of any company other than Hilton
Common Stock, but excluding any cash dividends or distributions other than
Extraordinary Cash Distributions (as defined below) and dividends referred to
in clause (i) above). Hilton will be entitled (but will not be required) to
make upward adjustments in the Common Equivalent Rate, the Minimum Redemption
Rate, the Optional Conversion Rate and the Call Price as Hilton, in its
discretion, determines to be advisable, in order that any stock dividends,
subdivision of shares, distribution of rights to purchase stock or securities,
or distribution of securities convertible into or exchangeable for stock (or
any transaction which could be treated as any of the foregoing transactions
under Section 305 of the Code) hereafter made by Hilton to its stockholders
will not be taxable. "Extraordinary Cash Distribution" means, with respect to
any consecutive 12-month period, all cash dividends and cash distributions on
the Hilton Common Stock during such period (other than cash dividends and cash
distributions for which a prior adjustment to the Common Equivalent Rate, the
Minimum Redemption Rate, and Optional Conversion Rate was previously made) to
the extent such dividends and distributions exceed, on a per share of Hilton
Common Stock basis, 10% of the average daily closing price of the Hilton
Common Stock over such period. All adjustments to the Common Equivalent Rate,
the Minimum Redemption Rate, and the Optional Conversion Rate will be
calculated to the nearest one one-hundredth of a share of Hilton Common Stock.
No adjustment in the Common Equivalent Rate, the Minimum Redemption Rate, or
the Optional Conversion Rate will be required unless such adjustment would
require an increase or decrease of at least one percent therein; provided,
however, that any adjustments which, by reason of the foregoing, are not
required to be made will be carried forward and taken into account in any
subsequent adjustment. All adjustments will be made successively.
 
  Whenever the Common Equivalent Rate, the Minimum Redemption Rate, and the
Optional Conversion Rate are adjusted as provided in the preceding paragraph,
Hilton will file with the transfer agent for the shares of Hilton PRIDES a
certificate with respect to such adjustment, make a prompt public announcement
thereof and mail a notice to holders of the shares of Hilton PRIDES providing
specified information with respect to such adjustment. At least 10 business
days before taking any action that could result in certain adjustments in the
Common Equivalent Rate, the Minimum Redemption Rate, and the Optional
Conversion Rate, Hilton will notify each holder of shares of Hilton PRIDES
concerning such proposed action.

  In the event that the Stock Split is not effected by Hilton, the Common
Equivalent Rate, the Minimum Redemption Rate, the Optional Conversion Rate and
the Current Market Price, as stated herein, shall be divided by four.
 
ADJUSTMENT FOR CERTAIN CONSOLIDATIONS OR MERGERS
 
  In case of: (i) any consolidation or merger to which Hilton is a party
(other than a merger or consolidation in which Hilton is the surviving or
continuing corporation and in which the shares of Hilton Common Stock
outstanding immediately before the merger or consolidation remain unchanged);
(ii) any sale or transfer to another corporation of the property of Hilton as
an entirety or substantially as an entirety; or (iii) any statutory exchange
of securities with another corporation (other than in connection with a merger
or consolidation), each share of Hilton PRIDES will, after consummation of
such transaction, be subject to (A) conversion at the option of the holder
into the kind and amount of securities, cash or other property receivable upon
consummation of such transaction by a holder of the number of shares of Hilton
Common Stock into which such share of Hilton PRIDES might have been converted
immediately before consummation of such transaction, (B) conversion on the
Mandatory Conversion Date into the kind and amount of securities, cash, or
other property receivable upon consummation of such transaction by a holder of
the number of shares of Hilton Common Stock into which such share of Hilton
PRIDES would have been converted if the conversion on the Mandatory Conversion
Date had occurred immediately before the date of consummation of such
transaction, plus the right to receive cash in an amount equal to all accrued
and unpaid dividends on such share of Hilton PRIDES (other than previously
declared dividends payable to a holder of record as of a prior date), and (C)
redemption on any redemption date in exchange for the kind and amount of
securities, cash, or other property receivable upon consummation of such
transaction by a holder of the number of shares of Hilton Common Stock that
would have been issuable at the Call Price in effect on such redemption date
upon a redemption of such share of Hilton PRIDES immediately before
consummation of such transaction, assuming that, if the Notice Date for such
redemption is not before such transaction, the Notice Date had been the date
of such transaction; and assuming in each case that such holder of shares of
Hilton Common Stock failed to exercise rights of election, if any, as to the
kind or amount of securities, cash, or other property receivable upon
consummation of such transaction (provided that, if the kind or amount of
securities, cash, or other property receivable upon consummation of such
transaction is not the same for each non-electing share, then the kind and
amount of securities, cash, or other property receivable upon consummation of
such transaction for each non-electing share will be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares). The
kind and amount of securities into or for which the shares of Hilton PRIDES
will be convertible or redeemable after consummation of such transaction will
be subject to adjustment as described above under the caption "Conversion
Adjustments" following the date of consummation of such transaction. Hilton
may not become a party to any such transaction unless the terms thereof are
consistent with the foregoing.
 
FRACTIONAL SHARES
 
  No fractional shares of Hilton Common Stock will be issued upon redemption
or conversion of shares of Hilton PRIDES. In lieu of any fractional share
otherwise issuable in respect of the aggregate number of shares of Hilton
PRIDES of any holder that are redeemed or converted on any redemption date or
upon mandatory conversion or any optional conversion, such holder will be
entitled to receive an amount in cash equal to the same fraction of the: (i)
Current Market Price of the Hilton Common Stock, determined as of the second
Trading Day immediately preceding the Notice Date, in the case of redemption;
or (ii) Closing Price (as defined in the Certificate of Designation) of the
Hilton Common Stock determined (A) as of the fifth Trading Day immediately
preceding the Mandatory Conversion Date, in the case of mandatory conversion,
or (B) as of the second Trading Day immediately preceding the effective date
of conversion, in the case of an optional conversion by a holder.
 
LIQUIDATION RIGHTS
 
  In the event of any voluntary or involuntary liquidation, dissolution, or
winding up of Hilton, and subject to the rights of holders of any other series
of Hilton Preferred Stock, the holders of outstanding shares of Hilton
 
                                      67
<PAGE>
 
PRIDES are entitled to receive for each share of Hilton PRIDES an amount equal
to $11.125 per share, plus accrued and unpaid dividends thereon, out of the
assets of Hilton available for distribution to stockholders, before any
distribution of assets is made to holders of Hilton Common Stock or any other
capital stock ranking junior to Hilton PRIDES upon liquidation, dissolution or
winding up. The shares of Hilton PRIDES will rank on a parity upon liquidation
with any Parity Preferred Stock.
 
  If, upon any voluntary or involuntary liquidation, dissolution, or winding
up of Hilton, the assets of Hilton are insufficient to permit the payment of
the full preferential amounts payable with respect to the shares of Hilton
PRIDES and all other series of Parity Preferred Stock, the holders of shares
of Hilton PRIDES and of all other series of Parity Preferred Stock will share
ratably in any distribution of assets of Hilton in proportion to the full
respective preferential amounts to which they are entitled. After payment of
the full amount of the liquidating distribution to which they are entitled,
the holders of shares of Hilton PRIDES will not be entitled to any further
participation in any distribution of assets by Hilton. A consolidation or
merger of Hilton with or into one or more other corporations (whether or not
Hilton is the corporation surviving such consolidation or merger), or a sale,
lease or exchange of all or substantially all of the assets of Hilton, will
not be deemed to be a voluntary or involuntary liquidation, dissolution, or
winding up of Hilton.
 
VOTING RIGHTS
 
  The holders of shares of Hilton PRIDES shall have the right with the holders
of Hilton Common Stock to vote in the election of directors and upon each
other matter coming before any meeting of the holders of Hilton Common Stock
on the basis of four-fifths (4/5ths) of a vote for each share of Hilton PRIDES
held, after giving effect to the Stock Split. The holders of shares of Hilton
PRIDES and the holders of Hilton Common Stock will vote together as one class
on such matters except as otherwise provided by law or the Certificate of
Incorporation of Hilton.
 
  In the event that dividends on the shares of Hilton PRIDES or any other
series of Hilton Preferred Stock are in arrears and unpaid for six quarterly
dividend periods, or if any other series of Hilton Preferred Stock is entitled
for any other reason to exercise voting rights, separate from the Hilton
Common Stock, to elect any Directors of Hilton ("Preferred Stock Directors"),
the holders of the shares of Hilton PRIDES (voting separately as a class with
holders of all other series of Preferred Stock upon which like voting rights
have been conferred and are exercisable with the Hilton PRIDES as a class),
with each share of Hilton PRIDES entitled to one vote on this and other
matters in which such Preferred Stock votes as a group, will be entitled to
vote for the election of two Directors, such Directors to be in addition to
the number of Directors constituting the Board of Directors of Hilton
immediately before the accrual of such right. Such right, when vested, will
continue until all dividends in arrears and payable on the shares of Hilton
PRIDES and such other series of Preferred Stock have been paid in full and the
right of any other such series of Preferred Stock to exercise voting rights,
separate from the Hilton Common Stock, to elect Preferred Stock Directors of
Hilton terminates or has terminated, and, when so paid and any such
termination occurs or has occurred, such right of the holders of the shares of
Hilton PRIDES will cease. The term of office of any Director elected by the
holders of the shares of Hilton PRIDES and such other series will terminate on
the earlier of (i) the next annual meeting of stockholders at which a
successor has been elected and qualified or (ii) the termination of the right
of holders of the shares of Hilton PRIDES and such other series to vote for
such Directors.
 
  Hilton will not, without the approval of the holders of at least 66 2/3% of
the shares of Hilton PRIDES then outstanding: (i) amend, alter or repeal any
of the provisions of the Certificate of Incorporation or Bylaws of Hilton so
as to affect adversely the powers, preferences, or rights of the holders of
the shares of Hilton PRIDES then outstanding or reduce the minimum time for
any required notice to which the holders of the shares of Hilton PRIDES then
outstanding may be entitled (an amendment of the Certificate of Incorporation
to authorize or create, or to increase the authorized amount of, Hilton Common
Stock or other Junior Stock or any stock of any class ranking on a parity with
the shares of Hilton PRIDES being deemed not to affect adversely the powers,
preferences, or rights of the holders of the shares of Hilton PRIDES); (ii)
authorize or create or increase the authorized amount of any stock of any
class (whether or not convertible into capital stock of any class) ranking
 
                                      68
<PAGE>
 
prior to the shares of Hilton PRIDES either as to the payment of dividends or
the distribution of assets upon liquidation, dissolution or winding up of
Hilton; or (iii) merge or consolidate with or into any other corporation,
unless each holder of shares of Hilton PRIDES immediately preceding such
merger or consolidation receives or continues to hold in the resulting
corporation the same number of shares, with substantially the same rights and
preferences, as correspond to the shares of Hilton PRIDES so held.
 
  Hilton will not, without the approval of the holders of at least a majority
of the shares of Hilton PRIDES then outstanding, increase the authorized
number of shares of Preferred Stock to more than 60,000,000 shares.
 
  Notwithstanding the provisions summarized in the preceding two paragraphs,
no such approval described therein of the holders of the shares of Hilton
PRIDES will be required if, at or before the time when such amendment,
alteration, or repeal is to take effect or when the authorization, creation,
increase or issuance of any such prior or parity stock or convertible security
is to be made, or when such consolidation or merger, voluntary liquidation,
dissolution, or winding up, sale, lease, conveyance, purchase, or redemption
is to take effect, as the case may be, provision is made for the redemption of
all shares of Hilton PRIDES at the time outstanding.
 
TRANSFER AGENT AND REGISTRAR
 
  ChaseMellon Shareholder Services, L.L.C. will act as transfer agent and
registrar for, and paying agent for the payment of dividends on, the shares of
Hilton PRIDES.
 
MISCELLANEOUS
 
  Upon issuance, the shares of Hilton PRIDES will be fully paid and
nonassessable. Holders of shares of Hilton PRIDES have no preemptive rights.
Hilton will at all times reserve and keep available out of its authorized and
unissued Hilton Common Stock, solely for issuance upon the conversion or
redemption of shares of Hilton PRIDES, such number of shares of Hilton Common
Stock as will from time to time be issuable upon the conversion or redemption
of all the shares of Hilton PRIDES then outstanding. Shares of Hilton PRIDES
redeemed for, or converted into, Hilton Common Stock or otherwise reacquired
by Hilton will resume the status of authorized and unissued shares of
Preferred Stock, undesignated as to series, and will be available for
subsequent issuance.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a summary of certain United States Federal tax consequences
of the ownership and disposition of the Hilton PRIDES. Hilton does not intend
to seek a ruling from the Service with respect to any of these tax
consequences. This summary is intended for general information only and deals
only with holders who are initial holders of shares of Hilton PRIDES and who
hold shares of Hilton PRIDES as capital assets within the meaning of Section
1221 of the Code. It does not address aspects of taxation, other than Federal
income taxation, or all tax consequences that may be relevant in the
particular circumstances of each holder (some of which, such as dealers in
securities, banks, insurance companies and tax-exempt organizations, may be
subject to special rules). Stock having terms closely resembling those of
shares of Hilton PRIDES has not been the subject of any regulation, ruling or
judicial decision currently in effect, and there can be no assurance that the
Service will adopt the positions set forth below. There can be no assurance
that future changes in applicable law or administration and judicial
interpretations thereof, any of which could have a retroactive effect, will
not adversely affect the tax consequences discussed herein or that there will
not be differences of opinion as to the interpretation of applicable law. For
purposes of this summary, "U.S. Holder" means a citizen or resident of the
United States, a corporation, partnership or other entity created or organized
under the laws of the United States or any State, or an estate or trust the
income of which is subject to United States Federal income taxation regardless
of its source, and "non-U.S. Holder" means a holder other than a U.S. Holder.
Certain aspects of United States Federal income and estate tax relevant to a
non-U.S. Holder are discussed separately below. Holders of Bally PRIDES should
consult their tax advisors with respect to the application of the United
States
 
                                      69
<PAGE>
 
Federal income tax laws to their particular situations as well as any tax
consequences arising under the laws of any state, local or foreign taxing
jurisdiction.
 
  Dividends. Dividends paid on shares of Hilton PRIDES out of Hilton's current
or accumulated earnings and profits will be taxable as ordinary income.
Certain corporate holders will generally qualify for the 70 percent
intercorporate dividends-received deduction subject to satisfaction of the
minimum holding period (generally at least 46 days) and other applicable
requirements. The dividends-received deduction is not available in computing a
corporate U.S. Holder's liability for alternative minimum tax.
 
  Under certain circumstances, a corporation that receives an "extraordinary
dividend" as defined in Section 1059(c) of the Code, is required to reduce its
stock basis by the non-taxed portion of such dividend. Generally, quarterly
dividends not in arrears paid to an original holder of shares of Hilton PRIDES
will not constitute extraordinary dividends under Section 1059(c). Under
Section 1059(f), any dividend with respect to "disqualified preferred stock"
is treated as an "extraordinary dividend." Hilton does not believe that shares
of Hilton PRIDES will be determined to constitute "disqualified preferred
stock."
 
  Call or Conversion Premium. Under certain circumstances, Section 305 of the
Code requires that any excess of the redemption price of preferred stock over
its issue price is includable in income, before receipt, as a constructive
dividend. While the issue is not free from doubt due to a lack of authority
directly on point, a holder of shares of Hilton PRIDES should not be required
to include any call or conversion premium in income as a redemption premium
under Section 305 of the Code.
 
  Redemption or Mandatory or Optional Conversion into Hilton Common Stock. As
a general rule, gain or loss will not be recognized by a holder upon the
redemption of shares of Hilton PRIDES for shares of Hilton Common Stock or the
conversion of shares of Hilton PRIDES into shares of Hilton Common Stock if no
cash is received. Income may be recognized, however, to the extent Hilton
Common Stock or cash is received in payment of accrued and unpaid dividends
upon a redemption or conversion. Such income would likely be characterized as
dividend income although some uncertainty exists as to the appropriate
characterization of payments in satisfaction of accrued and undeclared
dividends. A holder who received cash in lieu of a fractional share will be
treated as having received such fractional share of Hilton Common Stock and as
having exchanged it for cash in a transaction subject to Section 302 of the
Code and related provisions. Such exchange should generally result in capital
gain or loss measured by the difference between the cash received for the
fractional share interest and the holder's tax basis in the fractional share
interest. A holder who received an Additional Cash Payment would realize gain
or loss equal to the difference between (i) the sum of the Additional Cash
Payment and the fair market value of the Hilton Common Stock received and (ii)
the aggregate tax basis of the Hilton PRIDES surrendered therefor. Any loss
would not be recognized, however, and gain would be recognized, but not in
excess of the Additional Cash Payment received. For a discussion of the rules
governing the computation of gain and the determination of the character of
any gain, see "The Merger--Tax Consequences of the Merger--Receipt of
Additional Cash Payment."
 
  Generally, a holder's tax basis in the Hilton Common Stock received upon the
redemption or conversion of shares of Hilton PRIDES, other than shares of
Hilton Common Stock taxed upon receipt, will equal the adjusted tax basis of
the redeemed or converted shares of Hilton PRIDES (exclusive of any basis
allocable to a fractional share interest) and the holding period of such
Common Sock will include the holding period of the redeemed or converted
shares of Hilton PRIDES. As a general rule, a holder's tax basis in shares of
Hilton Common Stock taxed upon receipt will equal the fair market value
thereof and the holding period for such Hilton Common Stock will begin on the
day following the redemption or conversion.
 
  Adjustment of Conversion Rates. Certain adjustments to the Common Equivalent
Rate and the Optional Conversion Rate to reflect Hilton's distribution of
certain rights, warrants, evidences of indebtedness, securities or other
assets to holders of Hilton Common Stock may result in constructive
distributions taxable as dividends to the holders of shares of Hilton PRIDES
which may constitute (and cause other dividends to constitute) "extraordinary
dividends" to corporate holders of Hilton PRIDES as described above.
 
                                      70
<PAGE>
 
  Conversion of Hilton PRIDES after Dividend Record Date. If a holder whose
shares of Hilton PRIDES have not been called for redemption, surrenders such
shares for conversion into shares of Hilton Common Stock after a dividend
record date but before payment of the dividend, such holder will be required
to pay Hilton an amount equal to such dividend upon conversion. The holder
would likely recognize the dividend payment which is received as income, and
would increase the basis of the Hilton Common Stock received by the amount
paid to Hilton in connection with the receipt of such dividend.
 
  Backup Withholding. Certain non-corporate U.S. Holders may be subject to
backup withholding at a rate of 31% on dividends and certain consideration
received upon the redemption or conversion of shares of Hilton PRIDES unless
such holder provides proof of an applicable exemption or a correct taxpayer
identification number, and otherwise complies with applicable requirements of
the backup withholding rules.
 
  Proposed Legislation. The Clinton Administration has proposed tax
legislation which would, among other things, decrease the dividend-received
deduction for certain corporate holders from 70 percent to 50 percent, require
the immediate recognition of income for certain "extraordinary dividends,"
including dividends received with respect to stock the basis of which would be
reduced below zero, and require that a shareholder satisfy a 46-day holding
period for each dividend received. No assurance can be given concerning the
likelihood of enactment of such legislative proposals, and holders of shares
of Hilton PRIDES are urged to consult their tax advisors concerning such
legislative proposals and their possible application to the Hilton PRIDES.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS
 
  Dividends. In general, dividends (including constructive distributions
taxable as dividends) paid to a non-U.S. Holder will be subject to United
States withholding tax at a 30 percent rate (or a lower rate prescribed by an
applicable tax treaty) unless the dividends are either: (i) effectively
connected with a trade or business carried on by the non-U.S. Holder within
the United States; or (ii) if a tax treaty applies, attributable to a United
States permanent establishment maintained by the non-U.S. Holder. Dividends
effectively connected with such trade or business or attributable to such
permanent establishment will generally be subject to United States Federal
income tax at regular rates and, in the case of a non-U.S. Holder which is a
corporation, may be subject to the branch profits tax. To determine the
applicability of a tax treaty providing for a lower rate of withholding,
dividends paid to an address in a foreign country are presumed under current
Treasury regulations to be paid to a resident of that country.
 
  Gain on Redemption or Conversion into Hilton Common Stock. A non-U.S. Holder
generally will not be subject to United States Federal income tax on any gain
recognized on a disposition, redemption or conversion (a "disposition") of a
share of Hilton PRIDES unless: (i) all or a portion of such gain is treated as
dividend income; (ii) subject to the exception discussed below, Hilton is or
has been a "United States real property holding corporation" (a "USRPHC")
within the meaning of Section 897(c)(2) of the Code at any time within the
shorter of the five-year period preceding such disposition or such non-U.S.
Holder's holding period (the "Required Holding Period"); (iii) the gain is
effectively connected with a trade or business carried on by the non-U.S.
Holder within-the United States or, if a tax treaty applies, attributable to a
United States permanent establishment maintained by the non-U.S. Holder; (iv)
in the case of a non-U.S. Holder who is an individual, who holds the share as
a capital asset, and who is present in the United States for 183 days or more
in the taxable year of the disposition, either (a) such non-U.S. Holder has a
"tax home," (as defined for U.S. Federal income tax purposes) in the United
States and the gain from the disposition is not attributable to an office or
other fixed place of business maintained by such non-U.S. Holder outside of
the United States or (b) the gain from the disposition is attributable to an
office or other fixed place of business maintained by such non-U.S. Holder in
the United States; or (v) the non-U.S. Holder is subject to a tax pursuant to
provisions of the Code applicable to certain United States expatriates. If a
non-U.S. Holder fails to satisfy clause (iii) above, the non-U.S. Holder will
be taxed on the net gain derived from the disposition under regular graduated
U.S. Federal income tax rates (and, with respect to corporate non-U.S.
Holders, may also be subject to the branch profits tax described above). If an
individual non-U.S. Holder fails to satisfy clause (iv) above, the non-U.S.
Holder generally will be subject to a
 
                                      71
<PAGE>
 
30 percent tax on the gain derived from the disposition, which gain may be
offset by U.S. capital losses recognized within the same taxable year of such
disposition (notwithstanding the fact that the non-U.S. Holder is not
considered a resident of the United States).
 
  A corporation is generally a USRPHC if the fair market value of its United
States real property interests equals or exceeds 50 percent of the sum of the
fair market value of its worldwide real property interests plus its other
assets used or held for use in a trade or business. While not free from doubt,
Hilton believes that it currently is a USRPHC. However, a non-U.S. Holder
would generally not be subject to tax or withholding in respect of such tax on
gain from a disposition of a share of Hilton PRIDES by reason of Hilton's
USRPHC status if Hilton PRIDES are regularly traded on an established
securities market ("regularly traded") during the calendar year in which such
disposition occurs provided that such non-U.S. Holder does not own, actually
or constructively, Hilton PRIDES with a fair market value in excess of 5
percent of the fair market value of all Hilton PRIDES outstanding at any time
during the Required Holding Period. Hilton believes that Hilton PRIDES will be
treated as regularly traded.
 
  If Hilton is or has been a USRPHC within the Required Holding Period, and if
a non-U.S. Holder owns in excess of 5 percent of the fair market value of
Hilton PRIDES (as described in the preceding paragraph), such non-U.S. Holder
of shares of Hilton PRIDES will be subject to United States Federal income tax
at regular graduated rates under certain rules ("FIRPTA tax") on gain
recognized on a disposition of shares of Hilton PRIDES. Any amount withheld
pursuant to such withholding tax will be creditable against such non-U.S.
Holder's United States Federal income tax liability. Following conversion of
one or more of a non-U.S. Holder's shares of Hilton PRIDES into shares of
Hilton Common Stock, such non-U.S. Holder will be subject to the same FIRPTA
tax rules with respect to the sale, exchange, or other disposition of shares
of Hilton Common Stock by a non-U.S. Holder (as well as the exception
discussed above) as are applicable to a disposition of one or more shares of
Hilton PRIDES by such non-U.S. Holder. Non-U.S. Holders are urged to consult
their tax advisors concerning the potential applicability of these provisions.
 
  Federal Estate Tax. Shares of Hilton PRIDES owned or treated as owned by an
individual who is not a citizen or resident (as defined for United States
Federal estate tax purposes) of the United States at the time of death will be
includable in the individual's gross estate for United States Federal estate
tax purposes unless an applicable estate tax treaty provides otherwise.
 
  Backup Withholding and Information Reporting Requirements. Under current
United States Treasury regulations, Hilton must report annually to the Service
and to each non-U.S. Holder the amount of dividends paid to and the tax
withheld with respect to such holder. These information reporting requirements
apply regardless of whether withholding was reduced or eliminated by an
applicable tax treaty. Copies of these information returns may also be made
available under the provisions of a specific treaty or agreement to the tax
authorities in the country in which the non-U.S. Holder resides. United States
backup withholding tax (which generally is a withholding tax imposed at the
rate of 31% on certain payments to persons that fail to furnish the
information required under the United States information reporting
requirements) will generally not apply to dividends paid on shares of Hilton
PRIDES to a non-U.S. Holder at an address outside the United States. Backup
withholding may apply to such payments unless the payee is able to establish
its status as a non-U.S. Holder.
 
  The payment of the proceeds from the disposition of shares of Hilton PRIDES
to or through the United States office of a broker will be subject to
information reporting and backup withholding at a rate of 31% unless the owner
certifies, among other things, its status as a non-U.S. Holder under penalties
of perjury or otherwise establishes an exemption. The payment of the proceeds
from the disposition of shares of Hilton PRIDES to or through a non-U.S.
office of a broker will generally, except as noted below, not be subject to
backup withholding and information reporting. In the case of proceeds from a
disposition of shares of Hilton PRIDES paid to or through a non-U.S. office of
a U.S. broker or paid to or through a non-U.S. office of a non-U.S. broker
that is: (i) a "controlled foreign corporation" for United States Federal
income tax purposes; or (ii) a person 50% or more of whose gross income from
all sources for a certain three-year period was effectively connected with a
United States trade or business, (a) backup withholding will not apply unless
the broker has actual knowledge
 
                                      72
<PAGE>
 
that the owner is not a non-U.S. Holder, and (b) information reporting will
not apply if the broker has documentary evidence in its files that the owner
is non-U.S. Holder (unless the broker has actual knowledge to the contrary).
 
  Any amounts withheld under the backup withholding rules from a payment to a
non-U.S. Holder will be refunded (or credited against the non-U.S. Holder's
United States Federal income tax liability, if any), provided that the
required information is furnished to the Service.
 
  The United States Treasury has recently issued proposed regulations regarding
the withholding and information reporting rules discussed above. In general, the
proposed regulations do not alter the substantive withholding and information
reporting requirements but unify current certification procedures and forms and
clarify and modify reliance standards. If finalized in their current form, the
proposed regulations would generally be effective for payments made after
December 31, 1997, subject to certain transition rules.

                           REGULATION AND LICENSING
 
  Each of Hilton and Bally hold gaming licenses or permits in each
jurisdiction in which it operates gaming activities. In each such
jurisdiction, certain regulatory requirements must be complied with and/or
certain approvals must be obtained prior to the consummation of the Merger.
Upon consummation of the Merger, Bally will cease to exist and Hilton will
succeed to Bally's operations and will be subject to such laws and regulations
to which Bally's operations were subject prior to the Merger. Unless the
context otherwise requires, the discussion below assumes the Merger has been
consummated.
 
  Under provisions of Nevada, Mississippi, Missouri, Louisiana and New Jersey
and other gaming laws, and Hilton's Certificate of Incorporation, certain
securities of Hilton are subject to restrictions on ownership which may be
imposed by specified governmental authorities. Such restrictions may require
the holder to dispose of the securities or, if the holder refuses to make such
disposition, Hilton may be obligated to repurchase the securities.
 
  Nevada Gaming Laws. The ownership and operation of casino gaming facilities
in Nevada are subject to (i) the Nevada Gaming Control Act and the regulations
promulgated thereunder (the "Nevada Act") and (ii) various local regulations.
Hilton's gaming operations are subject to the licensing and regulatory control
of the Nevada Gaming Commission (the "Nevada Commission"), the Nevada State
Gaming Control Board (the "Nevada Board"), and, depending on the facility's
location, the Clark County Liquor and Gaming Licensing Board (the "CCB") and
the City of Reno. The Nevada Commission, the Nevada Board, the CCB and the
City of Reno are collectively referred to as the "Nevada Gaming Authorities."
 
  The laws, regulations and supervisory procedures of the Nevada Gaming
Authorities are based upon declarations of public policy that are concerned
with, among other things: (i) the prevention of unsavory or unsuitable persons
from having a direct or indirect involvement with gaming at any time or in any
capacity; (ii) the establishment and maintenance of responsible accounting
practices and procedures; (iii) the maintenance of effective controls over the
financial practices of licensees, including the establishment of minimum
procedures for internal fiscal affairs and the safeguarding of assets and
revenues, providing reliable record keeping and requiring the filing of
periodic reports with the Nevada Gaming Authorities; (iv) the prevention of
cheating and fraudulent practices; and (v) providing a source of state and
local revenues through taxation and licensing fees. Change in such laws,
regulations and procedures could have an adverse effect on Hilton's gaming
operations.
 
  Each subsidiary of Hilton that operates a casino in Nevada (individually, a
"Corporate Licensee" and collectively, the "Corporate Licensees") is required
to be licensed by the Nevada Gaming Authorities. The gaming license requires
the periodic payment of fees and taxes and is not transferable. Hilton is
required to be registered by the Nevada Commission as a publicly traded
corporation ("Registered Corporation") and as such, it is required
periodically to submit detailed financial and operating reports to the Nevada
Commission and furnish any other information that the Nevada Commission may
require. No person may become a stockholder of, or receive any percentage of
profits from, a Corporate Licensee without first obtaining licenses and
approvals from the Nevada Gaming Authorities.
 
  The Nevada Gaming Authorities may investigate any individual who has a
material relationship to, or material involvement with, Hilton or any of its
Corporate Licensees in order to determine whether such individual is suitable
or should be licensed as a business associate of a gaming licensee. Officers,
directors and certain key employees of a Corporate Licensee must file
applications with the Nevada Gaming Authorities and may be required to be
licensed or found suitable by the Nevada Gaming Authorities. Officers,
directors and key employees of Hilton who are actively and directly involved
in gaming activities of any Corporate Licensee may be required to be licensed
or found suitable by the Nevada Gaming Authorities. The Nevada Gaming
Authorities may deny an application for licensing for any cause which they
deem reasonable. A finding of suitability is comparable to licensing, and both
require submission of detailed personal and financial information followed by
a thorough investigation. An applicant for licensing or an applicant for a
finding of suitability must pay all costs of the investigation. Changes in
licensed positions must be reported to the Nevada Gaming Authorities and in
addition to their authority to deny an application for a finding of
suitability or licensing, the Nevada Gaming Authorities have the jurisdiction
to disapprove a change in a corporate position.
 
                                      74
<PAGE>
 
  If the Nevada Gaming Authorities were to find an officer, director or key
employee unsuitable for licensing or unsuitable to continue having a
relationship with Hilton or any Corporate Licensee, Hilton and the Corporate
Licensee would have to sever all relationships with such person. In addition,
the Nevada Commission may require Hilton or a Corporate Licensee to terminate
the employment of any person who refused to file appropriate applications.
Determinations of suitability or questions pertaining to licensing are not
subject to judicial review in Nevada.
 
  Hilton and all Corporate Licensees are required to submit detailed financial
and operating reports to the Nevada Commission. Substantially all material
loans, leases, sales of securities and similar financing transactions of a
Corporate Licensee must be reported to, or approved by, the Nevada Commission.
 
  If it were determined that the Nevada Act was violated by a Corporate
Licensee, the gaming licenses it holds could be limited, conditioned,
suspended or revoked, subject to compliance with certain statutory and
regulatory procedures. In addition, the Corporate Licensee, Hilton and the
persons involved could be subject to substantial fines for each separate
violation of the Nevada Act at the discretion of the Nevada Commission.
Further, a supervisor could be appointed by the Nevada Commission to operate a
Corporate Licensee's gaming property and, under certain circumstances,
earnings generated during the supervisor's appointment (except for the
reasonable rental value of the gaming property) could be forfeited to the
State of Nevada. Limitation, conditioning or suspension of any gaming license
of a Corporate Licensee or the appointment of a supervisor could (and
revocation of any gaming license would) have a material adverse effect on
Hilton's gaming operations.
 
  Any beneficial holder of Hilton Common Stock, Hilton PRIDES, or any other
voting security of Hilton ("Hilton Voting Securities"), regardless of the
number of shares owned, may be required to file an application, be
investigated, and have such person's suitability as a beneficial holder of
Hilton Voting Securities determined if the Nevada Commission has reason to
believe that such ownership would otherwise be inconsistent with the declared
policies of the State of Nevada. The applicant must pay all costs of the
investigation incurred by the Nevada Gaming Authorities in conducting any such
investigation.
 
  The Nevada Act requires any person who acquires beneficial ownership of more
than 5% of Hilton Voting Securities to report the acquisition to the Nevada
Commission. The Nevada Act requires that beneficial owners of more than 10% of
Hilton Voting Securities apply to the Nevada Commission for a finding of
suitability within thirty days after the Chairman of the Nevada Board mails
the written notice requiring such filing. Under certain circumstances, an
"institutional investor," as defined in the Nevada Act, which acquires
beneficial ownership of more than 10%, but not more than 15%, of Hilton Voting
Securities may apply to the Nevada Commission for a waiver of such finding of
suitability if such institutional investor holds Hilton Voting Securities for
investment purposes only. An institutional investor shall not be deemed to
hold Hilton Voting Securities for investment purposes unless Hilton Voting
Securities were acquired and are held in the ordinary course of business as an
institutional investor and not for the purpose of causing, directly or
indirectly, the election of a majority of the members of the Board of
Directors of Hilton, any change in Hilton's corporate charter, bylaws,
management, policies or operations of Hilton, or any of its gaming affiliates,
or any other action which the Nevada Commission finds to be inconsistent with
holding Hilton Voting Securities for investment purposes only. Activities
which are not deemed to be inconsistent with holding voting securities for
investment purposes only include: (i) voting on all matters voted on by
stockholders; (ii) making financial and other inquiries of management of the
type normally made by securities analysts for informational purposes and not
to cause a change in its management, policies or operations; and (iii) such
other activities as the Nevada Commission may determine to be consistent with
such investment intent. If the beneficial holder of voting securities who must
be found suitable is a corporation, partnership, limited partnership, limited
liability company or trust, it must submit detailed business and financial
information including a list of beneficial owners. The applicant is required
to pay all costs of investigation. Barron Hilton, Hilton's largest
stockholder, has been found suitable as a controlling stockholder of Hilton.
 
                                      75
<PAGE>
 
  Any person who fails or refuses to apply for a finding of suitability or a
license within 30 days after being ordered to do so by the Nevada Commission
or by the Chairman of the Nevada Board may be found unsuitable. The same
restrictions apply to a record owner if the record owner, after request, fails
to identify the beneficial owner. Any stockholder found unsuitable and who
holds, directly or indirectly, any beneficial ownership of Hilton Voting
Securities beyond such period of time as may be prescribed by the Nevada
Commission may be guilty of a criminal offense. Hilton is subject to
disciplinary action if, after it receives notice that a person is unsuitable
to be a stockholder or to have any other relationship with Hilton or a
Corporate Licensee, Hilton (i) pays that person any dividend or interest upon
any Hilton Voting Securities; (ii) allows that person to exercise, directly or
indirectly, any voting right conferred through securities held by that person;
(iii) pays remuneration in any form to that person for services rendered or
otherwise; or (iv) fails to pursue all lawful efforts to require such
unsuitable person to relinquish the voting securities for cash at fair market
value. Additionally, the CCB has the authority to approve all persons owning
or controlling the stock of any corporation controlling a gaming licensee.
 
  The Nevada Commission may, in its discretion, require the holder of any debt
security of a Registered Corporation to file applications, be investigated and
be found suitable to own such debt security of a Registered Corporation. If
the Nevada Commission determines that a person is unsuitable to own such
security, then pursuant to the Nevada Act, the Registered Corporation can be
sanctioned, including the loss of its approvals, if without the prior approval
of the Nevada Commission, it (i) pays to the unsuitable person any dividend,
interest or any distribution whatsoever; (ii) recognizes any voting right by
such unsuitable person in connection with such securities; (iii) pays the
unsuitable person remuneration in any form; or (iv) makes any payment to the
unsuitable person by way of principal, redemption, conversion, exchange,
liquidation or similar transaction.
 
  Hilton is required to maintain a current stock ledger in Nevada which may be
examined by the Nevada Gaming Authorities at any time. If any securities are
held in trust by an agent or by a nominee, the record holder may be required
to disclose the identity of the beneficial owner to the Nevada Gaming
Authorities. A failure to make such disclosure may be grounds for finding the
record holder unsuitable. Hilton is also required to render maximum assistance
in determining the identity of the beneficial owner of any Hilton Voting
Securities. The Nevada Commission has the power to require Hilton's stock
certificates to bear a legend indicating that the securities are subject to
the Nevada Act. However, to date, the Nevada Commission has not imposed such a
requirement on Hilton.
 
  Hilton may not make a public offering of its securities without the prior
approval of the Nevada Commission if the securities or the proceeds therefrom
are intended to be used to construct, acquire or finance gaming facilities in
Nevada, or to retire or extend obligations incurred for such purposes. On
September 28, 1995, the Nevada Commission granted Hilton prior approval to
make public offerings for a period of one year, subject to certain conditions
(the "Shelf Approval"). However, the Shelf Approval may be rescinded for good
cause without prior notice upon the issuance of an interlocutory stop order by
the Chairman of the Nevada Board. In addition to its applications for other
required approvals in order to consummate the Merger, Hilton has filed an
application seeking the approval of the Nevada Board and the Nevada Commission
for a renewal of the Shelf Approval until September 1997. The Hilton Common
Stock and the Hilton PRIDES will be offered pursuant to the renewed Shelf
Approval. However, there can be no assurances that any of the approvals will
be granted. Furthermore, any approval, if granted, does not constitute a
finding, recommendation or approval of the Nevada Gaming Authorities as to the
accuracy or adequacy of the prospectus or the investment merits of the
securities offered thereby. Any representation to the contrary is unlawful.
 
  Changes in control of Hilton through merger, consolidation, stock or asset
acquisitions, management or consulting agreements, or any act or conduct by a
person whereby such person obtains control, may not occur without the prior
approval of the Nevada Commission. Entities seeking to acquire control of a
Registered Corporation must satisfy the Nevada Board and Nevada Commission in
a variety of stringent standards prior to assuming control of such Registered
Corporation. The Nevada Commission may also require controlling stockholders,
officers, directors and other persons having a material relationship or
involvement with the entity
 
                                      76
<PAGE>
 
proposing to acquire control, to be investigated and licensed as part of the
approval process relating to the transaction.
 
  The Nevada legislature has declared that some corporate acquisitions opposed
by management, repurchases of voting securities and corporate defense tactics
affecting Nevada gaming licenses, and Registered Corporations that are
affiliated with those operations, may be injurious to stable and productive
corporate gaming. The Nevada Commission has established a regulatory scheme to
ameliorate the potentially adverse effects of these business practices upon
Nevada's gaming industry and to further Nevada's policy to: (i) assure the
financial stability of corporate gaming operators and their affiliates; (ii)
preserve the beneficial aspects of conducting business in the corporate form;
and (iii) promote a neutral environment for the orderly governance of
corporate affairs. Approvals are, in certain circumstances, required from the
Nevada Commission before Hilton can make exceptional repurchases of voting
securities above the current market price thereof and before a corporate
acquisition opposed by management can be consummated. The Nevada Act also
requires prior approval of a plan of recapitalization proposed by Hilton's
Board of Directors in response to a tender offer made directly to its
stockholders for the purpose of acquiring control of Hilton.
 
  License fees and taxes, computed in various ways depending on the type of
gaming or activity involved, are payable to the State of Nevada and to the
counties and cities in which the Corporate Licensees' respective operations
are conducted. Depending upon the particular fee or tax involved, these fees
and taxes are payable either monthly, quarterly or annually and are based upon
either: (i) a percentage of the gross revenues received; (ii) the number of
gaming devices operated; or (iii) the number of table games operated. A casino
entertainment tax is also paid by casino operators where entertainment is
furnished in connection with the selling of food or refreshments. Nevada
Corporate Licensees that hold a license as an operator of a slot route, or a
manufacturer's or distributor's license also pay certain fees and taxes to the
State of Nevada.
 
  Any person who is licensed, required to be licensed, registered, required to
be registered, or is under common control with such persons (collectively,
"Licensees"), and who proposes to become involved in a gaming venture outside
of Nevada is required to deposit with the Nevada Board, and thereafter
maintain, a revolving fund in the amount of $10,000 to pay the expenses of
investigation by the Nevada Board of the Licensee's participation in such
foreign gaming. The revolving fund is subject to increase or decrease in the
discretion of the Nevada Commission. Thereafter, Licensees are required to
comply with certain reporting requirements imposed by the Nevada Act. A
Licensee is also subject to disciplinary action by the Nevada Commission if it
knowingly violates any laws of the foreign jurisdiction pertaining to the
foreign gaming operation, fails to conduct the foreign gaming operation in
accordance with the standards of honesty and integrity required of Nevada
gaming operations, engages in activities that are harmful to the State of
Nevada or its ability to collect gaming taxes and fees, or employs a person in
the foreign operation who has been denied a license or finding of suitability
in Nevada on the ground of personal unsuitability.
 
  The sale of alcoholic beverages at establishments operated by a Corporate
Licensee is subject to licensing, control and regulation by applicable local
regulatory agencies. All licenses are revocable and are not transferable. The
agencies involved have full power to limit, condition, suspend or revoke any
such license, and any such disciplinary action could (and revocation would)
have a material adverse effect upon the operations of the Corporate Licensee.
 
  Louisiana Gaming Laws. The ownership and operation of a riverboat gaming
vessel in the State of Louisiana is subject to the Louisiana Riverboat
Economic Development and Gaming Control Act (the "Act"). As of May 1, 1996,
gaming activities have been regulated by the Louisiana Gaming Control Board
(the "Board"). The Board is responsible for investigating the background of
all applicants seeking a riverboat gaming license, issuing the license and
enforcing the laws, rules and regulations relating to riverboat gaming
activities.
 
  The applicant, its officers, directors, key personnel, partners and persons
holding a 5% or greater interest in the holder of a gaming license are
required to be found suitable by the Board. This requires the filing of an
 
                                      77
<PAGE>
 
extensive application to the Board disclosing personal, financial, criminal,
business and other information. On October 13, 1993, the Board's predecessor
issued a riverboat gaming license to the Queen of New Orleans, a joint venture
of which Hilton owns a 50% interest.
 
  The transfer of a Louisiana gaming license is prohibited under the Act. The
sale, assignment, transfer, pledge or disposition of securities which
represent 5% or more of the total outstanding shares issued by a holder of a
license is subject to Board approval and the transferee must be found
suitable. Ownership of the Hilton PRIDES may constitute ownership of Hilton
Common Stock for this purpose. In addition, all contracts and leases entered
into by a licensee are subject to approval and certain enterprises which
transact business with the licensee must be licensed.
 
  The Board must approve all security holders of the licensees and may find
any such security holder not qualified to own those securities. Louisiana law
may require that the charter or bylaws of the licensee provide that securities
are held subject to the condition that, if a holder is found to be
disqualified by the Board, the holder must dispose of the securities of the
licensee. If a security holder of a licensee is found disqualified, it will be
unlawful for the security holder: to (i) receive any dividend or interest with
regard to the securities; (ii) exercise, directly or indirectly, any rights
conferred by the securities; or (iii) receive any remuneration from the
licensee for services rendered or otherwise. The Board may impose similar
approval requirements on holders of securities of any intermediary or holding
company of the licensee, but may waive those requirements with respect to
holders of publicly-traded securities of intermediary and holding companies if
such holders do not have the ability to control the publicly-traded
corporation or elect one or more directors thereof.
 
  On April 19, 1996, the Louisiana legislature approved legislation mandating
statewide local elections on a parish-by-parish basis to determine whether to
prohibit or continue to permit three individual types of gaming. The
referendum will be brought before the Louisiana voters at the time of the 1996
presidential election and will determine whether each of the following types
of gaming will be prohibited or permitted in the following described Louisiana
parishes: (i) the operation of video draw poker devices in each parish; (ii)
the conduct of riverboat gaming in each parish that is contiguous to a
statutorily designated river or waterway or (iii) the conduct of land-based
casino gaming operations in Orleans Parish. If a majority of the voters in a
parish elect to prohibit one or more of the above-described gaming activities
in such parish, then no license or permit shall be issued to conduct such
prohibited gaming activity in such parish and no such gaming activity may be
permitted in that parish. If, however, riverboat gaming was previously
permitted in such parish, the legislation permits the current gaming operator
to continue riverboat gaming in that parish until the expiration of its gaming
license. Hilton's current riverboat gaming license expires on October 12,
1998, and Bally's current riverboat gaming license expires on March 24, 1999.
Further, in parishes where riverboat gaming is currently authorized and voters
elect to prohibit riverboat gaming, the legislation provides that the gaming
license shall not be reissued or transferred to any parish other than a parish
in which a riverboat upon which gaming is conducted is berthed. The current
legislation, however, does not provide for any moratorium on future local
elections on gaming. Further, the current legislation does not provide for any
moratorium that must expire before future local elections on gaming could be
mandated or allowed.
 
  New Jersey Gaming Laws. The ownership and operations of hotel-casino
facilities in Atlantic City, New Jersey are subject to extensive state
regulation under the New Jersey Casino Control Act (the "Act"). No hotel-
casino facility may operate unless various licenses and approvals are obtained
from New Jersey regulatory authorities, including the Casino Control
Commission (the "New Jersey Commission"). The New Jersey Commission is
authorized under the Act to adopt regulations covering a broad spectrum of
gaming and gaming related activities and to prescribe the methods and forms of
applications for licenses.
 
  In order to be granted a casino license under the Act, officers and
directors of a licensee and its employees who are employed in hotel or casino
operations in Atlantic City are required to be licensed or approved by the New
Jersey Commission. In addition, all contracts and leases entered into by a
licensee would be subject to approval and certain enterprises which transact
business with the licensee would themselves have to be licensed.
 
                                      78
<PAGE>
 
  The Act requires prior approval from the New Jersey Commission before
control of a casino licensee can be transferred. However, pursuant to an
interim casino authorization, the Act permits an entity that obtains the
securities of a casino licensee to acquire and own such securities upon
obtaining interim authorization from the New Jersey Commission. During the
period of interim authorization the securities of any such licensee must be
held in trust pursuant to the provisions of the Act. Prior to a determination
of final approval, the holder of the securities of the licensee retains
complete authority over the actions of the trustee of the trust. If the New
Jersey Commission thereafter denies qualification, the trustee of the trust
will be charged with disposing of the trust property.
 
  For a more complete description of the various applicable gaming regulatory
requirements under (i) the Nevada and Louisiana Gaming Laws, see "Additional
Information--Regulation and Licensing" in the Hilton Form 10-K and (ii) the
New Jersey Gaming Laws, see "Additional Information--Regulation and Licensing"
in the Hilton Form 10-K and "Gaming Regulation" in the Bally Form 10-K.
 
  Mississippi Gaming Laws. The ownership and operation of casino gaming
facilities in Mississippi are subject to extensive state and local regulation,
but primarily the licensing and regulatory control of the Mississippi Gaming
Commission and the Mississippi State Tax Commission. An owner and operator of
casino gaming facilities in Mississippi and its related holding companies must
register under the Mississippi Gaming Control Act (the "Mississippi Act") and
its gaming operations are subject to the licensing and regulatory control of
the Mississippi Gaming Commission and various local, city and county
regulatory agencies. Although not identical, the Mississippi Act is similar to
the Nevada Act. The adopted regulations of the Mississippi Gaming Commission
are also similar in many respects to the Nevada gaming regulations.
 
  Mississippi statutes and regulations give the Mississippi Gaming Commission
the discretion to require a suitability finding with respect to any person or
entity who acquired any security of an owner and operator of casino gaming
facilities in Mississippi regardless of the percentage of ownership. The
current policy of the Mississippi Gaming Commission is to require any person
or entity acquiring 5% or more of any voting securities of a public company
with a licensed subsidiary or private company licensee to be found suitable.
If the owner of voting securities who is required to be found suitable is a
corporation, partnership or trust, it must submit detailed business and
financial information including a list of beneficial owners. The applicant is
required to pay all costs of investigation. The sale of alcoholic beverages by
Hilton is subject to licensing, control and regulation by the Alcoholic
Beverage Control Division ("ABC") of the Mississippi State Tax Commission. An
ABC license is revocable and is not transferable. The Alcoholic Beverage
Control Division of the Mississippi State Tax Commission has full power to
limit, condition, suspend or revoke any such license. For a more complete
description of the various applicable gaming regulatory requirements under the
Mississippi Gaming Laws, see "Gaming Regulation--Mississippi Regulation" in
the Bally Form 10-K.
 
  Missouri Gaming Laws. In 1993, Missouri enacted the Missouri Gaming Law (the
"MGL") and established the Missouri Gaming Commission (the "MGC"), which is
responsible for the licensing and regulation of riverboat gaming in Missouri.
The number of licenses which may be granted is not specifically limited by
statute or regulation but may be subject to limitations imposed by the MGC.
The MGL grants specific powers and duties to the MGC to supervise riverboat
gaming and implement the MGL and take any other action as may be reasonable or
appropriate to enforce the MGL. The MGC may approve permanently moored
("dockside") riverboat casinos subject to specific criteria that includes the
economic interest of Missouri and the safety of the general public.
 
  Under the MGL, the ownership and operation of riverboat gaming facilities in
Missouri are subject to extensive state and local regulation. If a company is
granted a gaming license in Missouri, such company, any related subsidiaries
and its officers, directors, significant shareholders and employees will be
subject to regulation. The initial license and first subsequent license
renewal of an excursion gambling boat operator generally is for a period of
one year. The MGC, however, may reopen license hearings at any time and may
terminate or impose additional regulations upon a licensee at any time during
the term of a license. In addition to the owner's license and operator's
license for the riverboat, most individuals participating in gaming
 
                                      79
<PAGE>
 
operations are required to have an occupational license from the MGC.
Applicants and licensees are responsible to keep the application and any
requested materials current at all times, and this responsibility continues
throughout any period of licensure granted by the MGC. In addition, Missouri
has extensive licensing disclosure requirements. In August, 1996, the MGC
issued a riverboat gaming license to the Flamingo Hilton Riverboat Casino,
L.P., a limited partnership wholly-owned by Hilton.
 
  Pursuant to its rulemaking authority, the MGC has adopted certain
regulations which provide, among other things, that: (i) no gaming licensee or
occupational licensee may pledge, hypothecate or transfer in any way any
license, or any interest in a license, issued by the MGC; (ii) without first
notifying the MGC at least 60 days prior to such consummation of any of the
following transactions (and during such period the MGC may disapprove the
transaction or require the transaction to be delayed pending further
investigation) (a) a gaming licensee or a holding company affiliated with a
gaming licensee may not make a public issuance of debt, (b) a publicly held
gaming licensee or a publicly held holding company may not make any issuance
of an ownership interest equaling 5% or greater of the gaming licensee or
holding company (ownership of the Hilton PRIDES may constitute ownership of
Hilton Common Stock for this purpose) or (c) a person or entity may not pledge
or hypothecate an ownership interest in a gaming licensee that is not a
publicly held company or a holding company that is not a publicly held
company; provided that no such ownership interest may be transferred
voluntarily or involuntarily pursuant to any pledge without separate notice to
the MGC as required by the regulations; (iii) not later than 7 days after the
consummation of any transfer of ownership interest in a publicly held gaming
licensee, if such transfer would result in an entity or group of entities
acting in concert owning, directly or indirectly, a total amount of ownership
interest equaling 5% or greater of the ownership interest in the gaming
licensee, the transferee must report such consummation to the MGC; (iv) no
withdrawals of capital, loans, advances or distribution of any type of assets
in excess of 5% of accumulated earnings of a licensee to anyone with an
ownership interest in the licensee may occur without prior MGC approval; and
(v) the MGC may take action against a licensee or other person who has been
disciplined in another jurisdiction for gaming related activity.
 
                   GENERAL COMPARISON OF STOCKHOLDERS RIGHTS
 
  At the Effective Time, the holders of Bally Common Stock will become holders
of Hilton Common Stock and their rights will be governed by Hilton's
Certificate of Incorporation and Bylaws and by the DGCL, and the holders of
Bally PRIDES will become holders of Hilton PRIDES and their rights will be
governed by Hilton's Certificate of Incorporation and Bylaws and by the DGCL.
The following are summaries of certain differences between the rights of
holders of Bally Common Stock and holders of Hilton Common Stock. The rights
of holders of the Hilton PRIDES, which are substantially identical to the
rights of the holders of the Bally PRIDES, are described above under
"Description of Hilton PRIDES." Because each of Bally and Hilton are organized
under the DGCL, any differences in the rights of their stockholders arise
solely from differences in their respective Certificates of Incorporation and
Bylaws.
 
  The following discussion is not intended to be complete and is qualified in
its entirety by reference to the DGCL, Bally's Restated Certificate of
Incorporation and Bylaws and Hilton's Certificate of Incorporation and Bylaws.
 
  Authorized Capital. As of the date hereof, the total number of authorized
shares of capital stock of Hilton is 100,000,000 shares, consisting of
90,000,000 shares of Hilton Common Stock and 10,000,000 shares of Hilton
Preferred Stock and the total number of authorized shares of capital stock of
Bally is 150,000,000 shares, consisting of 120,000,000 shares of Bally Common
Stock and 30,000,000 shares of preferred stock, par value $1.00 per share, of
Bally, of which 15,525,000 shares are designated Bally PRIDES. Assuming
consummation of the Merger and approval of the Related Hilton Proposals,
immediately following the Merger, the total number of authorized shares of
capital stock of Hilton will be 424,832,700 shares, consisting of 400,000,000
shares of Hilton Common Stock and 24,832,700 shares of Hilton Preferred Stock,
14,832,700 shares of which shall be designated as Hilton PRIDES.
 
 
                                      80
<PAGE>
 
  Special Meetings of Stockholders. Bally's Bylaws provide that its Board of
Directors, Chairman of the Board of Directors or President may call a special
meeting of the stockholders. Hilton's Bylaws provide that special meetings of
the stockholders may be called only by the Chairman of the Board or the Board
of Directors pursuant to a resolution approved by a majority of the entire
Board of Directors.
 
  Number and Election of Directors. Bally's Bylaws provide for a Board of
Directors consisting of not fewer than three (3) directors, elected by a
plurality of votes cast at the stockholders' annual meeting at which each
director's term expires. The exact number of directors is to be determined by
an 80% vote of the then authorized number of directors or by an affirmative
vote of the holders of at least 80% of the voting stock of Bally.
 
  Hilton's Bylaws currently provide for a Board of Directors consisting of
eleven (11) directors. At the stockholders' annual meeting, each Hilton
director whose term expires at that meeting must be elected by a plurality
vote of the stockholders. However, Hilton's Bylaws provide that no share of
stock shall be voted on at any election of directors that was transferred
within twenty (20) days prior to such election.
 
  Classes and Terms of Directors. Bally's Restated Certificate of
Incorporation and Bylaws establish three (3) classes of directors, as nearly
equal in number of directors as possible, with each director elected for a
term expiring at the third succeeding annual meeting of stockholders after his
or her election. Hilton's Bylaws similarly provide that the Board of Directors
be classified into three (3) classes, each class of directors holding office
for a term of three (3) years.
 
  Removal of Directors. Bally's Restated Certificate of Incorporation provides
that a director may only be removed, with or without cause, at any time by the
vote or consent of the holders of at least 80% of the shares of voting stock
of Bally, voting as a single class. Hilton's Bylaws provide that any director
may be removed, with or without cause, by the affirmative vote of the holders
of at least 75% of the votes represented by all then outstanding shares of
voting stock, voting as a single class.
 
  Notices of Director Nominations and Stockholder Business. Bally's Bylaws
provide that to be timely, a stockholder's notice of nomination or proposed
business must be received not fewer than 40 nor more than 65 calendar days
before the annual meeting. If the public announcement of such meeting is not
made at least 50 days before the date of such meeting, the stockholder must
make a request not later than 10 calendar days after the announcement of the
meeting. Hilton's Bylaws provide that a stockholder's notice of a nomination
or of a 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.
 
  Business Combination Provisions. Each of Hilton and Bally is subject to
Section 203 of the DGCL. In addition, Hilton's Certificate of Incorporation
requires that combination transactions with any individual, firm, corporation
or other entity (other than Hilton or any subsidiary of Hilton) that owns 10%
or more of Hilton's voting stock be approved by the affirmative vote of at
least 75% of the voting power of the then outstanding capital stock of Hilton,
except that, if (i) such business combination transaction is approved by a
majority of disinterested directors of Hilton or (ii) certain enumerated price
and procedural requirements are satisfied, then only the affirmative vote of a
majority of the outstanding voting stock of Hilton is required for approval.
 
  Under Bally's Restated Certificate of Incorporation: (i) any merger or
consolidation of Bally or a subsidiary of Bally with; (ii) any sale, lease,
exchange or other disposition by Bally or a subsidiary of Bally of assets
constituting all or substantially all the assets of Bally and its
subsidiaries, taken as a whole, to; or (iii) any issuance or transfer by Bally
or any subsidiary of Bally of any voting securities of Bally (except for
voting securities issued pursuant to a stock option, purchase, bonus or other
plan) to, in each case, an entity or person holding 5% or more of the voting
stock of Bally, shall require the affirmative vote of at least 80% of the
voting power of the then outstanding capital stock of Bally; provided that
such a vote is not required if the Board of Directors of Bally shall have (i)
by resolution approved a memorandum of understanding with such 5% holder with
respect to, and substantially consistent with the transaction prior to the
time such entity became a 5% holder
 
                                      81
<PAGE>
 
or (ii) by resolution adopted by more than 80% of the directors of Bally then
in office approved such transaction at any time prior to its consummation.
 
  Amendment of Certificate of Incorporation and Bylaws. Under Bally's Restated
Certificate of Incorporation, the provisions thereof relating to: (i)
amendments to Bally's Restated Certificate of Incorporation; (ii) merger,
consolidation or sale of substantially all the assets of Bally or a subsidiary
of Bally and issuance or transfer of voting securities of Bally; and (iii)
removal of directors may not be amended except with the vote of stockholders
representing 80% of the voting power of Bally, voting together as a single
class. Amendments with respect to other provisions of Bally's Restated
Certificate of Incorporation require a majority vote. Stockholders may also
amend the Bylaws of Bally by a majority vote.
 
  Hilton's Certificate of Incorporation provides that the provisions contained
therein and in the Bylaws relating to the number, election and terms of
directors, nominating procedures, the bringing of stockholder business,
removal of directors, filling of vacancies, amending the Bylaws and certain
other matters cannot be amended by the stockholders without the affirmative
vote of at least 75% of Hilton's voting stock, voting together as a single
class.
 
  Dividend Payment, Liquidation Preference and Redemptions. Bally's Restated
Certificate of Incorporation permits the Board of Directors of Bally to issue
shares of preferred stock in such series and with such designations and
relative rights and preferences as may be determined by resolution. Pursuant
to Bally's Restated Certificate of Incorporation, dividends on outstanding
shares of Bally Preferred Stock shall be declared and paid, or set apart for
payment, before any dividends shall be declared and paid, or set apart for
payment, on the outstanding shares of Bally Common Stock with respect to the
same dividend period. Bally's Restated Certificate of Incorporation further
provides that the Board of Directors of Bally may, in establishing any series
of Bally Preferred Stock, establish further limitations on the payment of
dividends on Bally Common Stock while any dividends on shares of preferred
stock are accrued and unpaid.
 
  Hilton's Certificate of Incorporation also provides that the Board of
Directors shall have authority to issue shares of Hilton Preferred Stock from
time to time on such terms as it may determine, and to divide the Hilton
Preferred Stock into one or more classes or series and, in connection with the
creation of any such class or series, to fix by the resolution the
designation, powers and relative, participating, optional or other special
rights of such class or series, and the qualifications, limitations, or
restrictions thereof, to the fullest extent permitted by law.

                          OTHER PROPOSALS RELATING TO
                          THE HILTON SPECIAL MEETING
 
          APPROVAL OF AN INCREASE IN THE NUMBER OF AUTHORIZED SHARES
               OF HILTON COMMON STOCK AND HILTON PREFERRED STOCK
                     AND THE DESIGNATION OF HILTON PRIDES
 
  The Hilton Board has approved and adopted, subject to stockholder approval,
an amendment (the "Authorized Shares Amendment") to the Hilton Certificate of
Incorporation to: (i) increase the authorized number of shares of Hilton
Common Stock from 90,000,000 shares to 400,000,000 shares; (ii) increase the
authorized number of shares of Hilton Preferred Stock from 10,000,000 shares
to 24,832,700 shares; and (iii) designate 14,832,700 shares of Hilton
Preferred Stock as Hilton PRIDES.
 
  Reasons for Amendment. The purpose of the Authorized Shares Amendment is to:
(i) authorize a sufficient number of shares of Hilton Common Stock to effect
the Stock Split; (ii) make a sufficient number of authorized shares of Hilton
Common Stock available after consummation of the Merger to provide flexibility
for future issuance of Hilton Common Stock for business and financial
purposes; and (iii) make a sufficient number of authorized shares of Hilton
Preferred Stock available for the designation and issuance of up to 14,832,700
shares of Hilton PRIDES required to be issued in connection with the Merger.
 
  Except for issuance of Hilton Common Stock and Hilton PRIDES in connection
with the Merger, Hilton does not have any immediate plans, agreements,
arrangements, commitments or understandings with respect to the issuance of
any of the remaining additional shares of Hilton Common Stock or Hilton
Preferred Stock which would be authorized by the Authorized Shares Amendment.
 
  Principal Effects. The additional shares of Hilton Common Stock to be
authorized by the Authorized Shares Amendment would have rights identical to
the currently outstanding Hilton Common Stock. Adoption of the Authorized
Shares Amendment would not affect the rights of the holders of currently
outstanding Hilton Common Stock, except for effects incidental to increasing
the number of shares of Hilton Common Stock outstanding upon the issuance of
newly authorized shares of Hilton Common Stock. If the Authorized Shares
Amendment is approved by the Hilton stockholders, it will become effective
upon the filing of a Certificate of Amendment to Hilton's Certificate of
Incorporation with the Secretary of State of the State of Delaware, which is
expected to be effective prior to the close of business on the date of the
Hilton Special Meeting and, in any event, prior to the consummation of the
Merger.
 
  The proposal to amend Hilton's Certificate of Incorporation will be voted
upon by the stockholders of Hilton separately from each of the Hilton Merger
Proposal and the Related Hilton Proposals. HOWEVER, THE APPROVAL OF THE HILTON
MERGER PROPOSAL AND APPROVAL OF THE STOCK SPLIT IS CONDITIONED UPON APPROVAL
OF THE AUTHORIZED SHARES AMENDMENT BY THE STOCKHOLDERS OF HILTON. ACCORDINGLY,
A VOTE AGAINST THE PROPOSAL TO AMEND HILTON'S CERTIFICATE OF INCORPORATION
WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE HILTON MERGER PROPOSAL AND
PROPOSAL TO EFFECT THE STOCK SPLIT. THE HILTON BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS THAT HILTON STOCKHOLDERS VOTE "FOR" APPROVAL OF THE AUTHORIZED
SHARES AMENDMENT.
 
                                      83
<PAGE>
 
                      APPROVAL OF A FOUR-FOR-ONE SPLIT OF
                              HILTON COMMON STOCK
 
  The Board of Directors of Hilton has approved and adopted, subject to
stockholder approval, an amendment to Hilton's Certificate of Incorporation to
effect the Stock Split, pursuant to which each share of Hilton Common Stock
outstanding immediately prior to the Hilton Special Meeting will be subdivided
into four shares of Hilton Common Stock.
 
  Reasons for Stock Split. The objectives of the Stock Split are to shift the
trading range of the Hilton Common Stock to a level that will facilitate
increased trading activity and encourage round lot trading, which may be
expected to increase the liquidity and broaden the marketability of Hilton
Common Stock. For these reasons, the Board has determined that the Stock Split
would be in the best interests of Hilton and its stockholders.
 
  Principal Effects. The Stock Split will not affect the stockholders'
proportionate equity interest in Hilton or the rights of the stockholders with
respect to each share of Hilton Common Stock as to voting, dividends and other
matters. Since there is no consideration received by Hilton in connection with
the Stock Split, the overall capital of Hilton will not change solely as a
result of the Stock Split.
 
  Effective Date; Delivery of New Certificates. If the Stock Split is approved
by the stockholders of Hilton, it will become effective upon the filing of a
Certificate of Amendment to Hilton's Certificate of Incorporation with the
Secretary of State of the State of Delaware which is expected to be effective
prior to the close of business on the date of the Hilton Special Meeting (the
"Stock Split Record Date"). Subject to such approval, on or about October 24,
1996 (the "Stock Split Payment Date"), Hilton will mail a certificate
representing three (3) additional shares of Hilton Common Stock for each share
held on the Stock Split Record Date to holders of Hilton Common Stock as of
the Stock Split Record Date. Stockholders should retain their stock
certificates representing shares of Hilton Common Stock and should not send
them to Hilton or its transfer agent. In addition, Hilton stockholders
contemplating a sale between the Stock Split Record Date and the Stock Split
Payment Date should consult their brokers as to their entitlement to the split
shares.
 
  Tax Consequences. The following discussion is included for general
information only. Hilton stockholders should consult their personal tax
advisors to determine the particular consequences of the Stock Split,
including the applicability and effect of Federal, state, local and foreign
income and other taxes. No gain or loss will be recognized for Federal income
tax purposes on the receipt of additional shares of Hilton Common Stock in the
Stock Split. A stockholder's tax basis in the shares of Hilton Common Stock
held immediately prior to the Stock Split will be allocated proportionately
among the original shares and the additional shares issued as a result of the
Stock Split. The holding period of the shares of Hilton Common Stock received
by a holder will include the period during which the shares of Hilton Common
Stock owned immediately prior to the Stock Split were held.
 
  THE HILTON BOARD UNANIMOUSLY RECOMMENDS THAT HILTON STOCKHOLDERS VOTE "FOR"
  APPROVAL OF THE PROPOSAL TO AMEND HILTON'S CERTIFICATE OF INCORPORATION TO
                            EFFECT THE STOCK SPLIT.

                          APPROVAL OF THE ISSUANCE OF
                     HILTON COMMON STOCK AND HILTON PRIDES
                       PURSUANT TO THE MERGER AGREEMENT
 
  At the Hilton Special Meeting, Hilton stockholders will be asked to consider
and vote upon a proposal to approve the issuance pursuant to the Merger
Agreement of shares of Hilton Common Stock (estimated to be up to
approximately 62,273,733 shares, see "The Merger Agreement--Conversion of
Shares"), and 14,832,700 shares of Hilton PRIDES. As of August 15, 1996,
51,620,865 shares of Bally Common Stock and 14,832,700 shares of Bally PRIDES
were issued and outstanding and 10,652,868 shares of Bally Common Stock were
issuable pursuant to outstanding options and agreements and securities
convertible or exchangeable into shares of Bally Common Stock. Based upon such
number of shares, it is currently anticipated that up to approximately
62,273,733 shares of Hilton Common Stock (see "The Merger Agreement--
Conversion of Shares") and 14,832,700 shares of Hilton PRIDES will be issued
upon consummation of the Merger, after giving effect to the Stock Split.
 
  Reason for Authorization. The rules of the NYSE require the affirmative vote
of a majority of the votes cast in person or by proxy at the Hilton Special
Meeting to approve the issuance of shares of Hilton Common Stock and Hilton
PRIDES pursuant to the Merger Agreement.
 
  The Proposal to authorize the issuance of shares of Hilton Common Stock and
shares of Hilton PRIDES will be voted on upon by the stockholders of Hilton
separately from the Hilton Merger Proposal. HOWEVER, THE APPROVAL OF THE
HILTON MERGER PROPOSAL IS CONDITIONED UPON APPROVAL OF THE ISSUANCE OF SHARES
OF HILTON COMMON STOCK AND HILTON PRIDES PURSUANT TO THE MERGER. ACCORDINGLY,
A VOTE AGAINST THE PROPOSAL TO ISSUE ADDITIONAL SHARES OF HILTON COMMON STOCK
AND HILTON PRIDES WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE HILTON
MERGER PROPOSAL.
 
  THE HILTON BOARD UNANIMOUSLY RECOMMENDS THAT THE HILTON STOCKHOLDERS VOTE
"FOR" APPROVAL OF THE ISSUANCE OF HILTON COMMON STOCK AND HILTON PRIDES.

  share of Company Capital Stock that is directly owned by Acquiror or any
  subsidiary of Acquiror shall be canceled and retired and shall cease to
  exist and no consideration shall be delivered or deliverable in exchange
  therefor.
 
    (c) Conversion of Company Common Stock. (i) Subject to Section 3.3, each
  share of Common Stock, par value $.66 2/3 per share ("Company Common
  Stock"), of the Company, issued and outstanding immediately prior to the
  Effective Time (excluding shares cancelled in accordance with Section
  3.1(b)) together with the Company Rights attached thereto or associated
  therewith shall be converted into the right to receive a number of fully
  paid and non-assessable shares of Common Stock, par value $2.50 per share,
  of Acquiror ("Acquiror Common Stock") equal to the Common Conversion Number
  (the "Stock Consideration"); provided, however, that in the event the
  Determination Price is less than $108 (as adjusted pursuant to Section
  3.1(d), the "Target Amount"), each share of Company Common Stock shall be

  assessable shares of Acquiror Common Stock equal to the Common Conversion
  Number plus an amount in cash, not to exceed $3.00, equal to (i) the

  provided, further, that in the event the Determination Price is less than
  $80 (as adjusted pursuant to Section 3.1(d), the "Floor Amount"), Acquiror

  Intent Notice") that the board of directors of Acquiror elects to increase
  the Common Conversion Number such that the product of the Common Conversion
  Number and the Determination Price shall equal $20 (it being understood
  that notwithstanding such increase in the Common Conversion Number, the
  Cash Consideration shall remain the same). The Top-Up Intent Notice shall
  be delivered to the Company no later than 2:00 p.m. on the second Business
  Day prior to the Closing Date. If, in such case, Acquiror does not deliver
  a Top-Up Intent Notice, the Company shall have the right to give written
  notice to Acquiror (the "Termination Notice") that the Company elects to
  terminate this Agreement. The Termination Notice shall be delivered to
  Acquiror no later than 2:00 p.m. on the Business Day prior to the Closing
  Date.
 
    (ii) Pursuant to the Rights Agreement, dated as of July 14, 1988 (the

  of Chicago, as rights agent, one right issued under the Acquiror Rights
  Agreement (an "Acquiror Right") will be attached to each share of Acquiror
  Common Stock issued upon conversion of Company Common Stock in accordance
  with Section 3.1(c) and all references in this Agreement to Acquiror Common
  Stock shall be deemed to include the Acquiror Rights. As of the Effective
  Time, all shares of Company Common Stock and all Company Rights converted
  pursuant to Section 3.1(c) shall no longer be outstanding and shall
  automatically be canceled and retired and shall cease to exist, and each
  holder of a certificate representing any such shares of Company Common
  Stock and any such Company Rights shall cease to have any rights with
  respect thereto, except the right to receive, upon the surrender of any
  such certificates, certificates representing the shares of Acquiror Common
  Stock and any cash in lieu of fractional shares of Acquiror Common Stock to
  be issued or paid in consideration therefor upon surrender of such
  certificate in accordance with Section 3.2(e), and any dividends or other
  distributions to which such holder is entitled pursuant to Section 3.2(c),
  in each case without interest.
 
    (d) Certain Adjustments and Determinations. If, between the date of this
  Agreement and the Effective Time, the outstanding shares of Acquiror Common
  Stock or Company Common Stock shall have been changed into a different
  number of shares or a different class, by reason of any stock dividend,
  subdivision, reclassification, recapitalization, split, combination or
  exchange of shares, the Common Conversion Number, the Determination Price,
  the Target Amount and the Floor Amount specified in Section 3.1(c)
  correspondingly shall be adjusted to reflect such stock dividend,
  subdivision, reclassification, recapitalization, split, combination or
  exchange of shares. Acquiror intends to effect a 4-for-1 stock split of
  Acquiror Common Stock, and upon such stock split, the Common Conversion
  Number shall be 1.0 (as may
 
                                      A-7
<PAGE>
 
  be further adjusted pursuant to Section 3.1(c)), the Target Amount shall be
  $27 and the Floor Amount shall be $20; and, in the event the Determination
  Price is calculated on the basis of pre-split trading prices, the
  Determination Price shall be such amount divided by four or, if the
  Determination Price is calculated on the basis of pre-split and post-split
  trading prices, appropriate adjustments shall be made to calculate a
  comparable number.
 
    (e) Conversion of PRIDES. Each share PRIDES issued and outstanding at the
  Effective Time (other than shares to be canceled in accordance with Section
  3.1(b)) shall be converted into the right to receive one validly issued,
  fully paid and nonassessable share of New PRIDES, subsequent to the
  Effective Time. As of the Effective Time, all such shares of PRIDES shall
  no longer be outstanding and shall automatically be canceled and retired
  and shall cease to exist, and each holder of a certificate representing any
  such shares of PRIDES shall cease to have any rights with respect thereto,
  except the right to receive the shares of New PRIDES, to be issued in
  consideration thereof upon surrender of such certificate in accordance with
  Section 3.2(a) and any dividends or other distributions to which such
  holder is entitled to pursuant to Section 3.2(c), in each case without
  interest.
 
    (f) Stock Options; SARS. At the Effective Time, each then outstanding
  option to purchase shares of Company Common Stock under the Company's 1989
  Incentive Plan, 1993 Non-Employee Directors' Stock Option Plan and 1985
  Incentive Plan (collectively, the "Company Stock Option Plans"), whether or
  not then vested or exercisable in accordance with its terms (collectively,
  the "Options"), shall become exercisable in full and shall be settled in
  exchange for an amount of cash equal to the product of (1) the amount by
  which (A) the sum of (i) the product of the Common Conversion Number and
  the Determination Price plus (ii) the Cash Consideration (if any) exceeds
  (B) the exercise price per share of such Option and (2) the number of
  shares of Company Common Stock issuable pursuant to the unexercised portion
  of such Option, subject to any required withholding of taxes (such amount
  being hereinafter referred to as, the "Option Consideration"). At the
  Effective Time, each then outstanding stock appreciation right granted by
  the Company under any of the Company Stock Option Plans, whether or not
  then vested or exercisable in accordance with its terms (collectively, the
  "SARs"), shall become exercisable in full and shall be settled in exchange
  for an amount of cash equal to the product of (1) the amount by which (A)
  the sum of (i) the product of the Common Conversion Number and the
  Determination Price plus (ii) the Cash Consideration (if any) exceeds (B)
  the appreciation base per share of Company Common Stock for such SAR and
  (2) the number of shares of Company Common Stock covered by such SAR,
  subject to any required withholding of taxes (such amount being hereinafter
  referred to as, the "SAR Consideration"); provided, however, that with
  respect to each SAR issued in tandem with an Option, the payment pursuant
  to the immediately preceding sentence with respect to the corresponding
  Option shall be deemed to constitute full satisfaction and settlement of
  such SAR and the holder of such SAR will be entitled to no additional
  payment with respect to the SAR, and such SAR shall be cancelled.
  Notwithstanding the foregoing, with respect to any person subject to
  Section 16(a) of the Exchange Act, any amount of Option Consideration or
  SAR Consideration, as the case may be, shall be paid as soon as practicable
  after the first date payment can be made without liability to such person
  under Section 16(b) of the Exchange Act. From and after the Effective Time,
  the Options and SARs shall represent only the right of the holders of such
  Options and SARs to receive the payments specified above upon the surrender
  thereof. Upon receipt of the Option Consideration or the SAR Consideration
  (if any), as the case may be, the corresponding Option or the corresponding
  SAR, as the case may be, shall be canceled. The surrender of an Option or a
  SAR, as the case may be, to the Company in exchange for the Option
  Consideration or the SAR Consideration, as the case may be, shall be deemed
  a release of any and all rights the holder had or may have had in respect
  of such Option or such SAR. Except as otherwise agreed to by the parties
  hereto, (i) all Company Stock Option Plans shall terminate as of the
  Effective Time and the provisions in any other plan, program or arrangement
  providing for the issuance or grant of any other interest in respect of the
  capital stock of the Company or, except as set forth in Section 3.1(f) of
  the Company Disclosure Schedule, any Subsidiary thereof, shall be canceled
  as of the Effective Time, and (ii) the Company shall take all permitted
  action necessary to ensure that following the Effective Time no participant
  in any Company Stock Option Plan or other plans, programs or
 
                                      A-8
<PAGE>
 
  arrangements shall have any right thereunder to acquire equity securities
  of the Company, the Surviving Corporation or any Subsidiary thereof and to
  terminate all such plans.
 
  3.2 Exchange of Certificates. (a) Exchange Agent. Prior to the Effective
Time, Acquiror shall designate a bank or trust company to act as exchange
agent in the Merger (the "Exchange Agent"), and Acquiror shall deposit with
the Exchange Agent as of the Effective Time (or otherwise when requested by
the Exchange Agent from time to time in order to effect any exchange pursuant
to this Section 3.2) for the benefit of the holders of shares of Company
Common Stock and PRIDES for exchange in accordance with this Article III,
through the Exchange Agent, certificates evidencing the shares of Acquiror
Common Stock and New PRIDES issuable and the Cash Consideration (if any)
deliverable pursuant to Sections 3.1(c) and 3.1(d) in exchange for outstanding
shares of Company Common Stock and PRIDES. Such shares of Acquiror Common
Stock and PRIDES and Cash Consideration (if any), together with any dividends
or distributions with respect thereto with a record date after the Effective
Time, shall hereinafter be referred to as the "Exchange Fund." The Exchange
Agent shall, pursuant to irrevocable instructions, deliver the shares of
Acquiror Common Stock and New PRIDES issuable and the Cash Consideration (if
any) deliverable pursuant to Sections 3.1(c) and 3.1(d) out of the Exchange
Fund.
 
  (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, Acquiror shall instruct the Exchange Agent to mail to each
holder of record of a certificate or certificates that immediately prior to
the Effective Time evidenced outstanding shares of Company Capital Stock (the
"Certificates") whose shares were converted into the right to receive shares
of Acquiror Common Stock and Cash Consideration (if any) or New PRIDES, as the
case may be, pursuant to Section 3.1, (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other provisions as
Acquiror reasonably may specify) and (ii) instructions for use in effecting
the surrender of the Certificates in exchange for certificates evidencing
shares of Acquiror Common Stock or New PRIDES, as the case may be, and payment
of Cash Consideration, if applicable. Upon surrender of a Certificate for
cancellation to the Exchange Agent, together with such letter of transmittal,
duly executed, and such other customary documents as may be required by the
Exchange Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor (A) a certificate evidencing that number of whole shares of
Acquiror Common Stock or New PRIDES, as applicable, that such holder has the
right to receive pursuant to the provisions of Section 3.1, (B) in the case of
Acquiror Common Stock, payment evidencing the Cash Consideration (if any) and
cash in lieu of fractional shares of Acquiror Common Stock to which such
holder is entitled pursuant to Sections 3.1(c) and 3.2(e), and (C) any
dividends or other distributions to which such holder is entitled pursuant to
Section 3.2(c) (the shares of Acquiror Common Stock or New PRIDES, as the case
may be, cash, dividends and distributions described in clauses (A), (B) and
(C) being hereinafter collectively, the "Merger Consideration"), and the
Certificates so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of shares of Company Capital Stock that is not
registered in the transfer records of the Company, certificates evidencing the
proper number of shares of Acquiror Common Stock or New PRIDES, as applicable,
may be issued in accordance with this Article III to a person other than the
person in whose name the Certificate so surrendered is registered, if the
Certificate is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid or are not applicable. Until
surrendered as contemplated by this Section 3.2(b), each Certificate shall be
deemed at any time after the Effective Time to evidence only the right to
receive upon such surrender the appropriate Merger Consideration.
 
  (c) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to
Acquiror Common Stock with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to the shares
of Acquiror Common Stock or New PRIDES evidenced thereby, and no other part of
the Merger Consideration shall be paid to any such holder, until the holder of
such Certificate shall surrender such Certificate in accordance with this
Article III. Subject to the effect of Applicable Laws, following surrender of
any such Certificate, there shall be paid to the holder of the certificates
evidencing whole shares of Acquiror Common Stock or New PRIDES, as applicable,
issued in exchange therefor, without interest, (i) at the time of such
surrender, the amount of dividends or other
 
                                      A-9
<PAGE>
 
distributions with both a record date and payment date after the Effective
Time, but prior to surrender, payable with respect to such whole shares of
Acquiror Common Stock or New PRIDES, as applicable, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with
a record date after the Effective Time but prior to surrender and a payment
date occurring after surrender, payable with respect to such whole shares of
Acquiror Common Stock or New PRIDES as applicable. No interest shall be paid
on the Merger Consideration or such dividends or other distributions.
 
  (d) No Further Rights in Company Capital Stock. All shares of Acquiror
Common Stock and New PRIDES issued upon the surrender for exchange of
Certificates in accordance with the terms of this Article III (and any cash
paid pursuant to Section 3.2(c) or, in the case of Acquiror Common Stock,
Sections 3.1(c) and 3.2(e)) shall be deemed to have been issued (or paid) in
full satisfaction of all rights pertaining to such shares of Company Capital
Stock and Company Rights exchanged therefor represented by such Certificates;
subject, however, to the Surviving Corporation's obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time which may have been declared or made by the Company on such
shares of Company Capital Stock in accordance with the terms of this Agreement
or prior to the date of this Agreement and which remain unpaid at the
Effective Time and have not been paid prior to surrender, and there shall be
no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares of Company Capital Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation or the Exchange
Agent for any reason, they shall be canceled and exchanged as provided in this
Article III, except as otherwise provided by law.
 
  (e) No Fractional Shares. (i) No certificates or scrip representing
fractional shares of Acquiror Common Stock shall be issued upon the surrender
for exchange of Certificates, and such fractional share interests will not
entitle the holder thereof to vote or to any rights of a shareholder of
Acquiror.
 
  (ii) Notwithstanding any provision of this Agreement, each holder of shares
of Company Common Stock exchanged pursuant to the Merger who would otherwise
have been entitled to receive a fraction of a share of Acquiror Common Stock
(after taking into account all Certificates delivered by such holder) shall
receive, in lieu thereof, cash (without interest) in an amount equal to such
fractional part of a share of Acquiror Common Stock multiplied by the
Determination Price.
 
  (f) No Liability. Neither Acquiror nor the Company shall be liable to any
holder of shares of Company Capital Stock or Acquiror Common Stock, as the
case may be, for such shares of Acquiror Common Stock or New PRIDES (or
dividends or distributions with respect thereto) or cash in lieu of fractional
shares of Acquiror Common Stock which have been delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.
 
  3.3. Dissenting Shares. Notwithstanding any other provisions of this
Agreement to the contrary, in the event shares of Company Common Stock are
converted into the right to receive both the Stock Consideration and Cash
Consideration pursuant to Section 3.1(c), shares of Company Common Stock that
are outstanding immediately prior to the Effective Time and that are held by
stockholders who shall have not voted in favor of the Merger and who shall
have demanded properly in writing appraisal for such shares in accordance with
Section 262 of the DGCL (collectively, the "Dissenting Shares") shall not be
converted into or represent the right to receive the Stock Consideration and
Cash Consideration. Such stockholders instead shall be entitled to receive
payment of the appraised value of such shares of Company Common Stock held by
them in accordance with the provisions of such Section 262, except that all
Dissenting Shares held by stockholders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
shares of Company Common Stock under such Section 262 shall thereupon be
deemed to have been converted into and to have become exchangeable, as of the
Effective Time, for the right to receive, without any interest thereon, the
Stock Consideration and Cash Consideration upon surrender in the manner
provided in this Article III, of the Certificate or Certificates that formerly
evidenced such shares of Company Common Stock. The Company shall give Acquiror
(i) prompt notice of any demands for appraisal of shares of Company Common
Stock received by the Company and (ii) the opportunity to direct all
negotiations and proceedings with respect to any such demands. The Company
shall not, without the prior written consent of Acquiror, make any payment
with respect to, or settle, offer to settle, or otherwise negotiate any such
demands.

Company and customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements

  7.4 Reasonable Best Efforts; Notification. (a) Upon the terms and subject to
the conditions set forth in this Agreement, each of the parties agrees to use
all reasonable best efforts to take, or cause to be taken, all actions, and to
do, or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the
other transactions contemplated by this Agreement, including (i) the obtaining
of all necessary actions or nonactions, waivers, consents and approvals from
Governmental Authorities and the making of all necessary registrations and
filings (including filings with Governmental Authorities, if any) and the
taking of all reasonable steps as may be necessary to obtain an approval or
waiver from, or to avoid an action or proceeding by, any Governmental
Authority (including in respect of any Gaming Law), (ii) the obtaining of all
necessary consents, approvals or waivers from third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of any of the
transactions contemplated by this Agreement, including seeking to have any
stay or temporary restraining order entered by any court or other Governmental
Authority vacated or reversed and (iv) the execution and delivery of any
additional instruments necessary to consummate the transactions contemplated
by, and to fully carry out the purposes of, this Agreement.
 
  (b) The Company shall give prompt notice to Acquiror, and Acquiror shall
give prompt notice to the Company, of (i) any representation or warranty made
by it contained in this Agreement becoming untrue or inaccurate in any
material respect (including in the case of representations or warranties by
the Company or Acquiror, as applicable, such party's receiving knowledge of
any fact, event or circumstance which may cause any representation qualified
as to the knowledge of such party to be or become untrue or inaccurate in any
material respect) or (ii) the failure by it to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement; provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.
 
  7.5 Approval of Gaming Commissions; Regulatory Matters. Acquiror shall as
promptly as practicable, but in no event later than fifteen Business Days
following the execution and delivery of this Agreement, file or submit those
filings and other submissions under applicable Gaming Laws in connection with
the Merger, this Agreement and the transactions contemplated hereby, and to
respond as promptly as practicable to inquiries received from state or local
gaming authorities and to appear before such authorities as promptly as
practicable in order to obtain as soon as practicable those approvals and
consents required or necessary in connection with the Merger, this Agreement
or the transactions contemplated hereby. In addition, Acquiror shall, and
shall cause its Subsidiaries to (and shall use its reasonable efforts to cause
its affiliates other than its Subsidiaries to), if it is necessary to obtain
any regulatory approval for the Merger, disassociate themselves from any
person or persons deemed, or reasonably likely to be deemed, unacceptable by
any Gaming Commission and, in the case of any such person who is a nominee to
serve as a director of Acquiror or any of its Subsidiaries, Acquiror shall,
and shall cause its relevant Subsidiary or Subsidiaries to replace any such
director nominee with a suitable nominee. Acquiror shall keep the Company
apprised of the status of any communications with, and any inquiries or
requests for additional information from, the Gaming Commissions and shall
comply promptly with any such inquiry or request. Acquiror shall use its
reasonable best efforts to obtain all required approvals of the Gaming
Commissions for the consummation of the Merger no later than October 15, 1996.
 
  7.6 Supplemental Disclosure. The Company shall confer on a regular and
frequent basis with Acquiror, report on operational matters and promptly
notify Acquiror of, and furnish Acquiror with, any information it may
reasonably request with respect to, any event or condition or the existence of
any fact that would cause any of the conditions to Acquiror's obligation to
consummate the Merger not to be completed, and Acquiror shall
 
                                     A-28
<PAGE>
 
promptly notify the Company of, and furnish the Company any information it may
reasonably request with respect to, any event or condition or the existence of
any fact that would cause any of the conditions to the Company's obligation to
consummate the Merger not to be completed.
 
  7.7 Announcements. Prior to the Closing, neither the Company nor Acquiror
will issue any press release or otherwise make any public statement with
respect to this Agreement and the transactions contemplated hereby without the
prior consent of the other (which consent shall not be unreasonably withheld),
except as may be required by Applicable Law or applicable stock exchange
regulations, in which event the party required to make the release or
announcement shall, if possible, allow the other party reasonable time to
comment on such release or announcement in advance of such issuance. The
parties agree that the initial press release to be issued with respect to the
transactions contemplated by this Agreement shall be in the form heretofore
agreed to by the parties.
 
  7.8 No Solicitation. (a) From and after the date hereof until the Effective
Time, the Company shall not, nor shall it authorize any of its officers,
directors, employees, agents, investment bankers, attorneys, financial
advisors or other representatives (collectively, "Company Representatives") to
(i) solicit, initiate or knowingly encourage the submission of, any
Acquisition Proposal, (ii) enter into any agreement with respect to any
Acquisition Proposal, or (iii) participate in any discussions or negotiations
regarding, or furnish to any Person any non-public information with respect
to, or take any other action to knowingly facilitate any inquiries or the
making of any proposal that constitutes or would reasonably be expected to
lead to, an Acquisition Proposal; provided, however, that, notwithstanding
anything to the contrary in this Agreement, (i) the Company may participate in
discussions or negotiations with, and may furnish information concerning the
Company and its business, properties and assets to, a Third Party who, without
any solicitation by the Company or any Company Representatives after the date
of this Agreement, seeks to engage in such discussions or negotiations or
requests such information, if (1) the Board of Directors of the Company
determines, based on the advice of the Company's outside legal counsel, that
failing to engage in such discussion or negotiations or provide such
information would reasonably be expected to violate the fiduciary duties of
the Board of Directors of the Company to its stockholders and (2) prior to
engaging in discussions or negotiations with, or furnishing information to,
such Third Party, the Company shall receive from such Third Party an executed
confidentiality agreement in reasonably customary form on terms not more
favorable to such Person or entity than the terms contained in the
Confidentiality Agreement, and (ii) the Board of Directors of the Company may
take and disclose to the Company's stockholders a position with regard to a
tender offer or exchange offer contemplated by Rules 14d-9 and 14e-2(a)
promulgated under the Exchange Act and may make such disclosure to the
stockholders of the Company as may be required under Applicable Law; provided,
that the Board of Directors of the Company shall not recommend that the
stockholders of the Company tender their shares of Company Common Stock unless
such recommendation is permitted by Section 7.8(d).
 
  (b) The Company shall notify Acquiror of any Acquisition Proposal, including
the identity of the Third Party making any such Acquisition Proposal and the
material terms and conditions of any Acquisition Proposal.
 
  (c) As used in this Agreement, "Acquisition Proposal" shall mean any
proposal or offer from any person relating to (i) any direct or indirect
acquisition or purchase of more than 20% of either the capital stock of the
Company or the consolidated assets of the Company and its Subsidiaries taken
as a whole, (ii) any tender offer or exchange offer that if consummated would
result in any person beneficially owning 20% or more of the capital stock of
the Company or (iii) any merger, consolidation or business combination,
involving the Company other than the transactions contemplated by this
Agreement; provided, however, that any acquisition of shares of capital stock
of the Company by FMR Corp. (and its subsidiaries, Fidelity Management &
Research Company and Fidelity Management Trust Company) described in clause
(i) shall not constitute an Acquisition Proposal.
 
  (d) Notwithstanding anything to the contrary in this Agreement, the Board of
Directors of the Company shall be permitted from time to time to take the
following actions in the circumstances described below: (i) to withdraw or
modify its approval or recommendation of this Agreement or the Merger in a
manner adverse to Acquiror; or (ii) to approve or recommend or enter into an
agreement with respect to an Acquisition Proposal; if,
 
                                     A-29
<PAGE>
 
in each such case, (A) an Acquisition Proposal is publicly proposed, publicly
disclosed or communicated to the Company and (B) the Board of Directors of the
Company determines, based on the advice of the Company's outside legal
counsel, that such action is required in order to comply with its fiduciary
duties to the stockholders of the Company. No action by the Board of Directors
of the Company permitted by the preceding sentence (each, a "Permitted
Action") shall constitute a breach of this Agreement by the Company, provided
that such Permitted Action shall give rise to the rights of Acquiror set forth
in Section 9.3.
 
  7.9 Indemnification; Directors' and Officers' Insurance. (a) Until the
Effective Time the Company shall, and from and after the Effective Time,
Acquiror shall, indemnify, defend and hold harmless each person who is now, or
has been at any time prior to the date hereof or who becomes prior to the
Effective Time, an officer or director of the Company or any of its
Subsidiaries (the "Indemnified Parties") against all losses, claims, damages,
costs, expenses (including reasonable attorneys' fees and expenses),
liabilities or judgments or amounts that are paid in settlement of or in
connection with any threatened or actual claim, action, suit, proceeding or
investigation based in whole or substantially on, or arising in whole or
substantially out of the fact that such person is or was a director or officer
of the Company or any of its Subsidiaries, whether pertaining to any matter
existing or occurring at or prior to the Effective Time and whether asserted
or claimed prior to, or at or after, the Effective Time ("Indemnified
Liabilities"), including all Indemnified Liabilities based in whole or
substantially on, or arising in whole or substantially out of, or pertaining
to this Agreement or the transactions contemplated hereby, in each case to the
fullest extent a corporation is permitted under the DGCL to indemnify its own
directors or officers as the case may be (and the Company or the Surviving
Corporation, as the case may be, will pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
fullest extent permitted by law).
 
  (b) The Acquiror shall and shall cause the Subsidiaries of the Surviving
Corporation to keep in effect provisions in their respective Certificates of
Incorporation and By-laws providing for exculpation for director, officer and
employee liability and such corporation's indemnification of the Indemnified
Parties to the fullest extent permitted under the DGCL, which provisions shall
not be amended, repealed or otherwise modified for a period of six years after
the Effective Time in any manner that would adversely affect the rights
thereunder of individuals who at any time prior to the Effective Time were
directors, officers or employees of the Company in respect of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the transactions contemplated by this Agreement), unless such
modification is required by law.
 
  (c) For a period of six years after the Effective Time, Acquiror shall cause
to be maintained in effect the current policies of directors' and officers'
liability insurance maintained by the Company and its Subsidiaries (provided
that Acquiror may substitute therefor policies of at least the same coverage
and amounts containing terms and conditions that are no less advantageous in
any material respect to the Indemnified Parties) with respect to matters
arising before the Effective Time, provided that Acquiror shall not be
required to pay an annual premium for such insurance in excess of 150% of the
last annual premium paid by the Company prior to the date hereof, but in such
case shall purchase as much coverage as possible for such amount.
 
  (d) After the Effective Time, any Indemnified Party wishing to claim
indemnification under this Section, upon learning of any such action, suit,
claim, proceeding or investigation, shall notify Acquiror within 30 days
thereof; provided, however, that any failure so to notify Acquiror of any
obligation to indemnify such Indemnified Party or of any other obligation
imposed by this Section shall not affect such obligations except to the extent
Acquiror is materially prejudiced thereby. Acquiror shall be entitled to
assume the defense of any such action, suit, claim, proceeding or
investigation with counsel of its choice (who shall be reasonably acceptable
to the Indemnified Party), unless there is a conflict between the positions of
Acquiror, on the one hand, and the Indemnified Party, on the other, in which
event the Indemnified Party, together with all other similarly situated
Indemnified Parties in the same proceeding as a group, may retain one law firm
and one local counsel to represent them with respect to such matter, the cost
of which shall be borne by Acquiror. Neither Acquiror, on the one hand, nor
any Indemnified Party, on the other hand, may settle any such action, suit,
claim, proceeding or investigation without the prior written consent of the
other party, which consent shall not be unreasonably withheld or delayed.

  (e) The provisions of this Section 7.9 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Party, his or her heirs and
his or her personal representatives and shall be binding on all successors and
assigns of Acquiror and the Company.
 
  7.10 NYSE Listing. Acquiror shall use its reasonable efforts to cause the
shares of Acquiror Common Stock and New PRIDES to be issued in the Merger to
be approved for listing on the NYSE, subject to notice of official issuance,
prior to the Effective Time.
 
  7.11 Affiliates. Prior to the Closing Date, the Company shall deliver to
Acquiror a letter identifying all persons who are, at the time this Agreement
is submitted for approval to the stockholders of the Company, "affiliates" of
the Company for purposes of Rule 145 under the Securities Act. The Company
shall use its best efforts to cause each such person to deliver to Acquiror on
or prior to the Closing Date a written agreement substantially in the form
attached as Exhibit F.
 
  7.12 Rights Agreement. The Board of Directors of the Company shall take all
action necessary to render the Company Rights or any similar instrument
inapplicable to the Merger and to effect the conversion of the Company Rights
as of the Effective Date in accordance with Section 3.1(c) hereof.
 
  7.13 Employee Benefits. (a) Acquiror shall or shall cause the Surviving
Corporation to maintain in effect employee benefit plans and arrangements
which provide benefits which have a value which is substantially comparable,
in the aggregate, to the benefits provided by the Employee Benefit Plans (not
taking into account the value of any benefits under any such plans which are
equity based) for a period of one year after the Effective Time.
 
  (b) Acquiror shall honor all employment, severance and termination
agreements (including change in control provisions) of the employees of the
Company and its Subsidiaries.
 
  (c) For purposes of determining eligibility to participate and vesting, but
not accrual or entitlement to benefits (other than severance benefit accrual)
where length of service is relevant under any employee benefit plan or
arrangement of Acquiror or the Surviving Corporation, employees of the Company
and its Subsidiaries as of the Effective Time shall receive service credit for
service with the Company and any of its Subsidiaries to the same extent such
service was granted under the Employee Benefit Plans.
 
  (d) The provisions of Section 7.13(b) are intended to be for the benefit of
and shall be enforceable by each applicable employee and his heirs and
personal representatives and shall be binding on all successors and assigns of
Acquiror, the Surviving Corporation and its Subsidiaries.
 
  (e) In the event the Surviving Corporation terminates any Employee Benefit
Plan which provides pension, profit sharing or non-qualified deferred
compensation benefits, the Acquiror shall use its reasonable best efforts to
provide the participants and beneficiaries under any such plan with the means
to maintain and continue tax deferred treatment of such benefits, other than
through the use of an individual retirement account.
 
  7.14 Tax Treatment. Each of Acquiror and the Company shall use its best
efforts to cause the Merger to qualify as a reorganization under the
provisions of Sections 368(a) of the Code and use its reasonable best efforts
to obtain the opinions of counsel referred to in Sections 8.2(c) and 8.3(c).
 
  7.15 Transfer Taxes. The Company and Acquiror shall cooperate in the
preparation, execution and filing of all returns, questionnaires, applications
or other documents regarding any real property transfer or gains, sales, use,
transfer and stamp taxes, any transfer, recording, registration and other fees
and any similar taxes that become payable in connection with the transactions
contemplated by this Agreement ("Transfer Taxes"). The Company shall pay or
cause to be paid any such Transfer Taxes.
 
  7.16 Subsidiary Merger. Immediately prior to the Effective Time, the Company
will effect the merger of Bally's Casino, Inc., all of the common stock of
which is owned by the Company, with and into the Company
 
                                     A-31
<PAGE>
 
(the "Subsidiary Merger"), with the Company as the surviving corporation,
pursuant to the terms of a merger agreement which shall be in form and
substance reasonably satisfactory to Acquiror. At the effective time of the
Subsidiary Merger (the "Subsidiary Effective Time"), all outstanding shares of
Bally's Casino, Inc. common stock shall be cancelled and all outstanding
shares of Subsidiary Preferred Stock shall, by virtue of the merger and
without any action on the part of the holder thereof, be converted into the
right to receive a number of fully paid and non-assessable shares of Company
Common Stock (rounded-up to the nearest whole number) equal to the sum of: (i)
the number of shares of Company Common Stock exchangeable for the Subsidiary
Preferred Stock pursuant to the present terms of the Subsidiary Preferred
Stock, and (ii) the number of shares of Company Common Stock equal to the
quotient of (A) the product of (1) the average of the last sale prices of the
common stock of Bally Total Fitness Holding Corporation ("Bally Fitness")
quoted on the Nasdaq National Market (as reported by the Wall Street Journal)
for the thirty consecutive trading days ending on the third trading day prior
to the Subsidiary Effective Time, and (2) the number of shares of common stock
of Bally Fitness transferable pursuant to the present terms of the Subsidiary
Preferred Stock upon exchange of such Subsidiary Preferred Stock immediately
prior to the Subsidiary Effective Time, divided by (B) the average of the last
sale prices of the Company Common Stock quoted on the NYSE for the thirty
consecutive trading days ending on the third trading day prior to the
Subsidiary Effective Time. All shares of Company Common Stock issuable in the
Subsidiary Merger shall be deemed issued and outstanding immediately prior to
the Effective Time.

    (iii) this Agreement is terminated by Acquiror pursuant to Section 9.1(b)
  based on the failure of the condition set forth in Section 8.2(g);
 
and within one year following any such termination, an Acquisition Proposal is
consummated or the Company enters into an agreement with respect thereto, then
the Company shall pay to Acquiror within five business days following such

however, that in no event shall the Company be obligated to pay more than one
such fee with respect to all such occurrences.
 
  (c) If a Topping Fee is payable to Acquiror pursuant to Section 9.3(b), then
the Company shall also reimburse Acquiror (not later than five business days

incurred by it prior to such termination in connection with the proposed

Ladies & Gentlemen:
 
  You have requested our opinion regarding certain federal income tax
consequences of the merger (the "Merger") of Bally Entertainment Corporation
("BEC"), a Delaware corporation with and into Hilton Hotels Corporation
("HHC"), a Delaware corporation.
 
  In formulating our opinion, we examined such documents as we deemed
appropriate, including the Agreement and Plan of Merger among BEC and HHC
dated as of June , 1996 (the "Merger Agreement"), the Joint Proxy
Statement/Prospectus filed by BEC and HHC with the Securities and Exchange
Commission (the "SEC") on     , 1996 (the "Joint Proxy Statement"), and the
Registration Statement on Form S-4, as filed by HHC with the SEC on     ,
1996, in which the Joint Proxy Statement/Prospectus is included as a
prospectus, (with all amendments thereto, the "Registration Statement"). In
addition, we have obtained such additional information as we deemed relevant
and necessary through consultation with various officers and representatives
of BEC and HHC.
 
  Our opinion set forth below assumes (1) the accuracy of the statements and
facts concerning the Merger set forth in the Merger Agreement, the Joint Proxy
Statement, and the Registration Statement, (2) the consummation of the Merger
in the manner contemplated by, and in accordance with the terms set forth in,
the Merger Agreement, the Joint Proxy Statement and the Registration Statement
and (3) the accuracy of (i) the representations made by BEC, which are set
forth in the Certificate delivered to us by BEC, dated the date hereof, (ii)
the representations made by HHC, which are set forth in the Certificate
delivered to us by HHC, dated the date hereof and (iii) the representations
made by certain shareholders of BEC in Certificates delivered to us by such
persons dated the date hereof.
 
  Based upon the facts and statements set forth above, our examination and
review of the documents referred to above and subject to the assumptions set
forth above, we are of the opinion that for federal income tax purposes:
 
    1. The Merger will constitute a reorganization within the meaning of
  Section 368(a) of the Internal Revenue Code of 1986, as amended (the
  "Code").
 
    2. Each of BEC and HHC will be a party to the reorganization within the
  meaning of Section 368(b) of the Code.
 
    3. No gain or loss will be recognized by BEC or HHC as a result of the
  Merger.
 
We express no opinion concerning any tax consequences of the Merger other than
those specifically set forth herein.

Revenue Service and case law, any of which may be changed at any time with

Ladies & Gentlemen:
 
  You have requested our opinion regarding certain federal income tax
consequences of the merger (the "Merger") of Bally Entertainment Corporation
("BEC"), a Delaware corporation with and into Hilton Hotels Corporation
("HHC"), a Delaware corporation.
 
  In formulating our opinion, we examined such documents as we deemed
appropriate, including the Agreement and Plan of Merger among BEC and HHC
dated as of June , 1996, as amended (the "Merger Agreement"), the Joint Proxy
Statement/Prospectus filed by BEC and HHC with the Securities and Exchange
Commission (the "SEC") on     , 1996 (the "Joint Proxy Statement"), and the
Registration Statement on Form S-4, as filed by HHC with the SEC on     ,
1996, in which the Joint Proxy Statement/Prospectus is included as a
prospectus, (with all amendments thereto, the "Registration Statement"). In
addition, we have obtained such additional information as we deemed relevant
and necessary through consultation with various officers and representatives
of BEC and HHC.
 
  Our opinion set forth below assumes (1) the accuracy of the statements and
facts concerning the Merger set forth in the Merger Agreement, the Joint Proxy
Statement, and the Registration Statement, (2) the consummation of the Merger
in the manner contemplated by, and in accordance with the terms set forth in,
the Merger Agreement, the Joint Proxy Statement and the Registration Statement
and (3) the accuracy of (i) the representations made by BEC, which are set
forth in the Certificate delivered to us by BEC, dated the date hereof, (ii)
the representations made by HHC, which are set forth in the Certificate
delivered to us by HHC, dated the date hereof and (iii) the representations
made by certain shareholders of BEC in Certificates delivered to us by such
persons dated the date hereof.
 
  Based upon the facts and statements set forth above, our examination and
review of the documents referred to above and subject to the assumptions set
forth above, we are of the opinion that for federal income tax purposes:
 
    1. The Merger will constitute a reorganization within the meaning of
  Section 368(a) of the Internal Revenue Code of 1986, as amended (the
  "Code").
 
    2. Each of BEC and HHC will be a party to the reorganization within the
  meaning of Section 368(b) of the Code.
 
    3. No gain or loss will be recognized by a stockholder of BEC as a result
  of the Merger except (i) with respect to cash received by such stockholder
  in lieu of fractional shares and (ii) if a stockholder receives the
  Additional Cash Payment (as defined in the Joint Proxy Statement), gain, if
  any, realized by such stockholder pursuant to the Merger will be
  recognized, but not in excess of the Additional Cash Payment received.
 
  The foregoing opinions do not address the United States federal income tax
consequences of the Merger to a non-U.S. Holder (as defined in the Joint Proxy
Statement), including, without limitation, the application of Section 897 of
the Code to such holder. We express no opinion concerning any tax consequences
of the Merger other than those specifically set forth herein.

                                                                  TO APPENDIX A
 
                        BALLY ENTERTAINMENT CORPORATION
 
                                  CERTIFICATE
 
  In connection with your tax opinion dated        , 1996 regarding certain
federal income tax consequences of the merger (the "Merger") of Bally
Entertainment Corporation, a Delaware corporation ("BEC"), with and into
Hilton Hotels Corporation, a Delaware corporation ("HHC"), pursuant to the
Agreement and Plan of Merger dated as of June   , 1996, as amended (the
"Merger Agreement"), and recognizing that you will rely on this Certificate in
delivering said opinion, BEC hereby represents that the facts relating to the
Merger, as such facts are described in the Registration Statement of HHC filed
with the Securities and Exchange Commission (the "Commission") on        ,
1996 (and all amendments thereto) are, insofar as such facts pertain to BEC
true, correct, and complete in all material respects in accordance with
applicable rules of the Commission.
 
  BEC further represents the following:
 
    1. The fair market value of the HHC stock, cash (if any) and any cash in
  lieu of fractional shares received by each BEC shareholder will be
  approximately equal to the fair market value of the BEC stock surrendered
  in the exchange.
 
    2. There is no plan or intention of the shareholders of BEC who own 5
  percent or more of the BEC stock, and to the best of the knowledge of the
  management of BEC, there is no plan or intention on the part of the
  remaining shareholders of BEC to sell, exchange, or otherwise dispose of a
  number of shares of HHC stock received in the transaction that would reduce
  the BEC shareholders' ownership of HHC stock to a number of shares having a
  value on the date of the transaction of less than 50 percent of the value
  of all of the formerly outstanding stock of BEC as of the same date. For
  purposes of the representation, shares of BEC stock exchanged or redeemed
  for cash, surrendered by dissenters or exchanged for cash in lieu of
  fractional shares of HHC stock will be treated as outstanding BEC stock on
  the date of the transaction. Moreover, shares of BEC stock and shares of
  HHC stock held by BEC shareholders and otherwise sold, redeemed, or
  disposed of prior or subsequent to the transaction will be considered in
  making this representation.
 
    3. The liabilities of BEC assumed by HHC and the liabilities to which the
  transferred assets of BEC are subject were incurred by BEC in the ordinary
  course of its business.
 
    4. HHC, BEC and the shareholders of BEC will pay their respective
  expenses, if any, incurred in connection with the Merger.
 
    5. There is no intercorporate indebtedness existing between BEC and HHC
  that was issued, acquired, or will be settled at a discount.
 
    6. BEC is not an investment company as defined in Section
  368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as amended
  (the "Code").
 
    7. BEC is not under the jurisdiction of a court in a title 11 or similar
  case within the meaning of Section 368(a)(3)(A) of the Code.
 
    8. None of the compensation received by any shareholder-employees of BEC
  will be separate consideration for, or allocable to, any of their shares of
  BEC stock; none of the shares of HHC stock received by any shareholder-
  employees will be separate consideration for, or allocable to, any
  employment agreement, and the compensation paid to any shareholder-
  employees will be for services actually rendered and will be commensurate
  with amounts paid to third parties bargaining at arm's-length for similar
  services.

    9. The Merger Agreement represents the full and complete agreement
  between HHC and BEC regarding the Merger, and there are no other written or
  oral agreements regarding the Merger other than those expressly referred to
  in the Merger Agreement.
 
  IN WITNESS WHEREOF, BEC has executed this Certificate on this      day of
       , 1996.

    1. The fair market value of the HHC stock, cash (if any) and any cash in
  lieu of fractional shares received by each BEC shareholder will be
  approximately equal to the fair market value of the BEC stock surrendered
  in the exchange.
 
    2. HHC has no plan or intention to redeem or otherwise reacquire any HHC
  stock issued in the Merger.
 
    3. HHC has no plan or intention to sell or otherwise dispose of any of
  the assets of BEC acquired in the Merger, except for dispositions made in
  the ordinary course of business, or transfers to a direct wholly-owned
  subsidiary of HHC.*
 
    4. Following the Merger, HHC will continue the historic business of BEC
  or use a significant portion of BEC's historic business assets in HHC's
  business.
 
    5. HHC, BEC and the shareholders of BEC will pay their respective
  expenses, if any, incurred in connection with the Merger.
 
    6. There is no intercorporate indebtedness existing between BEC and HHC
  that was issued, acquired, or will be settled at a discount.
 
    7. None of the compensation received by any shareholder-employees of BEC
  will be separate consideration for, or allocable to, any of their shares of
  BEC stock; none of the shares of HHC stock received by any shareholder-
  employees will be separate consideration for, or allocable to, any
  employment agreement, and the compensation paid to any shareholder-
  employees will be for services actually rendered and will be commensurate
  with amounts paid to third parties bargaining at arm's-length for similar
  services.
 
    8. HHC does not own, nor has HHC owned during the past five years, more
  than a de minimus number of shares of stock of BEC.
 
    9. HHC is not an investment company as defined in Section
  368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as
  amended.
 
    10. The fair market value of the assets of BEC transferred to HHC will
  equal or exceed the sum of the liabilities assumed by HHC plus the amount
  of liabilities, if any, to which the transferred assets are subject.
 
    11. The payment of cash in lieu of fractional shares of HHC stock merely
  represents a mechanical rounding-off of fractional share interests as a
  result of the Merger and does not represent separately bargained for
  consideration.
- --------
*  May be modified on delivery of certificate to exclude any asset disposition
   not in the ordinary course, provided, however, that any such disposition
   does not prevent counsel for HHC and BEC from delivering the opinions
   required by Sections 8.2(c) and 8.3(d) of the Merger Agreement.
<PAGE>
 
    12. The Merger Agreement represents the full and complete agreement among
  HHC and BEC regarding the Merger, and there are no other written or oral
  agreements regarding the Merger other than those expressly referred to in
  the Merger Agreement.
 
  IN WITNESS WHEREOF, HHC has executed this Certificate on this      day of
       , 1996.

Ladies and Gentlemen:
 
  The undersigned has been advised that as of the date of this letter it may
be deemed to be an "affiliate" of Bally Entertainment Corporation, a Delaware
corporation (the "Company"), as such term is (i) 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 "Commission")
under the Securities Act of 1933, as amended (the "Securities Act"), or (ii)
used in and for purposes of Accounting Series Releases 130 and 135, as
amended, of the Commission. Pursuant to the terms of the Agreement and Plan of
Merger, dated as of June   , 1996 (as amended from time to time, the "Merger
Agreement"), between Hilton Hotels Corporation, a Delaware corporation
("Acquiror"), and the Company, the Company will be merged with and into
Acquiror (the "Merger"), with Acquiror continuing as the surviving
corporation.
 
  Pursuant to the Merger, each share of Common Stock of the Company owned by
the undersigned will be converted into the right to receive shares of Common
Stock, par value $2.50 per share, of Acquiror ("Acquiror Common Stock") on the
terms set forth in the Merger Agreement.
 
  The undersigned represents, warrants and covenants to Acquiror that, with
respect to all Acquiror Common Stock received by it as a result of the Merger:
 
    1. The undersigned shall not make any sale, transfer or other disposition
  of Acquiror Common Stock in violation of the Securities Act or the Rules
  and Regulations.
 
    2. The undersigned has carefully read this letter and the Merger
  Agreement and discussed the requirements of such documents and any other
  applicable limitations upon its ability to sell, transfer or otherwise
  dispose of Acquiror Common Stock to the extent it felt necessary, with its
  counsel or counsel for the Company.
 
    3. The undersigned has been advised that the issuance of Acquiror Common
  Stock to it pursuant to the Merger has been registered with the Commission
  under the Securities Act. However, the undersigned has also been advised
  that, since at the time the Merger Agreement was submitted for a vote of
  the stockholders of the Company, the undersigned may be deemed to have been
  an "affiliate" of the Company and the distribution by the undersigned of
  Acquiror Common Stock has not been registered under the Act, the
  undersigned may not sell, transfer or otherwise dispose of Acquiror Common
  Stock issued to it in the Merger unless (i) such sale, transfer or other
  disposition has been registered under the Securities Act or is made in
  conformity with Rule 145 under the Securities Act, or (ii) such sale,
  transfer or other disposition is otherwise exempt from registration under
  the Securities Act.
 
    4. The undersigned understands, that Acquiror is under no obligation to
  register under the Securities Act the sale, transfer or other disposition
  of Acquiror Common Stock by the undersigned or on its behalf or to take any
  other action necessary in order to make compliance with an exemption from
  such registration available.

* Appropriate conforming changes shall be made with respect to any affiliate
receiving New Prides.
<PAGE>
 
    5. The undersigned understands that Acquiror will give stop transfer
  instructions to Acquiror's transfer agents with respect to the Acquiror
  Common Stock and that the certificates for the Acquiror Common Stock issued
  to the undersigned, or any substitutions therefor, will bear a legend
  substantial to the following effect:
 
    "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 ONLY
    BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT, DATED
                , 1996, 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."
 
    6. The undersigned also understands that unless the transfer by the
  undersigned of its Acquiror Common Stock has been registered under the
  Securities Act or is a sale made in conformity with the provisions of Rule
  145, Acquiror reserves the right to place the following legend on the
  certificates issued to any 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 5 and 6
above shall be removed by delivery of substitute certificates without such
legend if Acquiror receives an opinion of counsel reasonably satisfactory to
Acquiror to the effect that such legend is not required for purposes of the
Securities Act. It is understood and agreed that such legends and the stop
orders referred to above will be removed if (i) two years shall have elapsed
from the date the undersigned acquired Acquiror Common Stock received in the
Merger and the provisions of Rule 145(d)(2) are then available to the
undersigned, (ii) three years shall have elapsed from the date the undersigned
acquired Acquiror Common Stock received in the Merger and the provisions of
Rule 145(d)(3) are then available to the undersigned, or (iii) Acquiror has
received either an opinion of counsel, which opinion and counsel shall be
reasonably satisfactory to Acquiror, or a "no-action" letter obtained by the
undersigned from the staff of the Commission, to the effect that the
restrictions imposed by Rule 145 under the Securities Act no longer apply to
the undersigned.

after the date of this letter.
 
                                          Sincerely,

Dear Sirs:
 
  You have requested our opinion as to the fairness from a financial point of
view to Hilton Hotels Corporation (the "Company") of the consideration to be
paid by the Company pursuant to the terms of the Agreement and Plan of Merger
dated as of June 6, 1996 (the "Agreement"), between the Company and Bally
Entertainment Corporation ("Bally") pursuant to which Bally will be merged
(the "Merger") with and into the Company.
 
  Pursuant to the Agreement, each issued and outstanding share of Bally common
stock, par value $.66 2/3 per share, together with the associated Company
Rights (as defined in the Agreement) (together "Bally Common Stock"), shall be
converted into the right to receive one quarter (0.25) of a share (the
"Exchange Ratio") of common stock of the Company, $2.50 par value per share
(the "Company Common Stock"), provided, however, that in the event the average
of the high and low sales prices of the Company Common Stock for the ten
consecutive trading days ending on the third trading day prior to Bally's
stockholders' meeting (the "Stockholders' Meeting") relating to the Merger
(the "Determination Price") is less than $108 and equal to or greater than
$80, each share of Bally Common Stock shall be converted into the right to
receive a number of shares of Company Common Stock equal to the Exchange Ratio
plus an amount in cash, not to exceed $3.00, equal to (i) the difference
between $108 and the Determination Price multiplied by (ii) the Exchange Ratio
(rounded to the nearest hundredth, or if there shall not be a nearest
hundredth, to the next highest hundredth) (the "Cash Consideration"); and,
provided, further, that in the event the Determination Price is less than $80,
the Company shall have the right to increase the Exchange Ratio ("Top-Up")
such that the Exchange Ratio multiplied by the Determination Price equals $20.
If, in such case, the Company does not Top-Up, Bally shall have the right to
terminate this Agreement no later than the business day prior to the date of
Bally's Stockholders' Meeting. The Exchange Ratio and the Determination Price
thresholds described above of 0.25, $108 and $80 shall be equal to 1.0, $27
and $20, respectively, in the event the Company effects a 4-for-1 stock split
as contemplated in the Agreement (the Exchange Ratio together with the Cash
Consideration, if any, the "Consideration").
 
  In arriving at our opinion, we have reviewed the June 5 1996 draft of the
Agreement, including exhibits thereto. We also have reviewed certain financial
and other information that was publicly available or furnished to us by the
Company and Bally including information provided during discussions with their
respective managements. Included in the information provided during
discussions with the respective managements were certain financial projections
of Bally for the period beginning January 1996 and ending December 1998
prepared by the management of Bally and certain financial projections of the
Company for the period beginning January 1996 and ending December 2000
prepared by the management of the Company. In addition, we have compared
certain financial and securities data of the Company and Bally with various
other companies whose securities are traded in public markets, reviewed the
historical stock prices and trading volumes of the common stock of Bally and
the Company, reviewed prices and premiums paid in certain other business
combinations and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion.

  In rendering our opinion, we have relied upon and assumed the accuracy,
completeness and fairness of all of the financial and other information that
was available to us from public sources, that was provided to us by the
Company, Bally or their respective representatives, or that was otherwise
reviewed by us. With respect to the financial projections supplied to us, we
have assumed that they have been reasonably prepared on the basis reflecting
the best currently available estimates and judgments of the management of the
Company and Bally as to the future operating and financial performance of the
Company and Bally. We have not assumed any responsibility for making any
independent evaluation of Bally's or the Company's 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 herein as to the
price at which the Company Common Stock will trade at any time. Our opinion
does not constitute a recommendation to any stockholder of the Company as to
how such stockholder should vote on the proposed transaction and related
issuance of the Company Common Stock. In addition, our opinion does not
address the underlying business decision of the Company to consummate the
transaction contemplated by the Agreement.

DLJ has acted as an underwriter for the Company with respect to the issuance
of its Convertible Debentures due 2006. DLJ has received usual and customary
compensation for the above-mentioned services.

of the opinion that the Consideration to be paid by the Company pursuant to
the Agreement is fair to the Company from a financial point of view.

(a) if the average of the daily high and low sales prices of the Hilton Shares
on the New York Stock Exchange for the ten consecutive trading days ending on
the third trading day prior to the special meeting of the Company's
stockholders held to vote upon the Merger (the "Determination Price") is less
than $108 and equal to or greater than $80, each such Share will be converted
into the right to receive a number of Hilton Shares equal to the Conversion
Number plus an amount in cash, not to exceed $3.00, equal to (i) the
difference between $108 and the Determination Price multiplied by (ii) the
Conversion Number, and (b) if the Determination Price is less than $80, Hilton
shall have the right to elect to increase the Conversion Number by the
quotient of $80 divided by the Determination Price, and if Hilton shall not
make such an election, the Company shall have the right to terminate the
Agreement. The total consideration in the form of Hilton Shares and cash, if
any, to be paid to the holders of Shares is referred to herein as the
"Aggregate Consideration."
 
  Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. We are familiar with the Company having acted as its financial
advisor in connection with, and having participated in certain of the
negotiations leading to, the Agreement. Goldman, Sachs & Co. is a full service
securities firm and in the course of its trading activities it may from time
to time effect transactions, for its own account or the account of customers,
and hold positions in securities or options on securities of the Company or
Hilton.
 
  In connection with this opinion, we have reviewed, among other things, the
Agreement; the Registration Statement on Form S-4, including the Joint Proxy
Statement/Prospectus relating to the special meetings of stockholders of the
Company and Hilton to be held in connection with the Merger; Annual Reports to
Stockholders and Annual Reports on Form 10-K of the Company and Hilton for the
five years ended December 31, 1995; and certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company and Hilton;
certain other communications from the Company and Hilton to their respective
stockholders; certain internal financial analyses and forecasts for the
Company and Hilton prepared by the Company's and Hilton's management,
respectively, including forecasts of certain cost savings, operating
efficiencies, and financial synergies (collectively, the "Synergies") expected
to be achieved as a result of the
 
                                      C-1

Merger prepared by the Company's management. We also have held discussions
with members of the senior management of the Company and Hilton regarding the
past and current business operations, financial condition and future prospects
of their respective companies and the combined company resulting from the
Merger, and regarding their assessment of the strategic fit and implications
of the Merger and the Synergies. In addition, we have reviewed the reported
price and trading activity for the Shares and Hilton Shares, compared certain
financial and stock market information for the Company and Hilton with similar
information for certain other companies the securities of which are publicly
traded, reviewed the financial terms of certain recent business combinations
in the gaming and lodging industries specifically and in other industries
generally. We have also reviewed and performed such other studies and analyses
as we considered appropriate.
 
  For purposes of this opinion, we have relied without independent
verification upon the accuracy and completeness of all of the financial and
other information reviewed by us or conveyed to us in discussions with senior
managements of the Company and Hilton. In addition, we have not made an
independent evaluation or appraisal of the assets and liabilities of the
Company or Hilton or any of their respective subsidiaries and we have not been
furnished with any such evaluation or appraisal. We have assumed, with your
consent, that the financial forecasts of the Company and Hilton (and the
assumptions and bases therefor), as well as the Synergies, have been
reasonably prepared on a basis reflecting the best currently available
judgments and estimates of the Company and Hilton, as the case may be, and
that such Synergies will be realized in the amounts and at the times
projected.
 
  Goldman, Sachs & Co. does not express any opinion as to the prices at which
the Hilton Shares will trade following the consummation of the Merger or the
prices at which the Shares or the Hilton Shares will trade between the
announcement of and the consummation of the Merger.
 
  Our opinion is directed to the Board of Directors of the Company and does
not constitute a recommendation to any stockholder of the Company as to how
such stockholder should vote at the stockholders' meeting held in connection
with the Merger.
 
  Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that as of the date hereof the
Aggregate Consideration to be received by the holders of Shares pursuant to
the Agreement is fair to such holders.
 
                                          Very truly yours,
 
                                          /s/ Goldman, Sachs & Co.

Board of Directors
Bally Entertainment Corporation
8700 West Bryn Mawr Avenue
Chicago, Illinois 60631
 
Gentlemen:
 
  Bally Entertainment Corporation (the "Company") and Hilton Hotels
Corporation ("Hilton") have entered into an Agreement and Plan Merger, dated
as of June 6, 1996 as amended by First Amendment to Merger Agreement (the
"Merger Agreement"), pursuant to which the Company will be merged with Hilton
in a transaction (the "Merger") in which each outstanding share of the
Company's common stock, par value $0.66-2/3 per share (the "Company Shares")
(other than any Company Shares that are owned by the Company, Hilton or any
subsidiary of Hilton, which will be cancelled), will be converted into the
right to receive one (the "Conversion Number") share of common stock, par
value $2.50 per share, of Hilton (the "Hilton Shares"), after giving effect to
a proposed stock split of the Hilton Shares whereby each Hilton Share will be
subdivided into four Hilton Shares (the "Stock Split"); provided, however,
that (a) if the average of the daily high and low sales prices of the Hilton
Shares (regular way), determined after giving effect to the Stock Split, as
shown on the New York Stock Exchange Composite Tape for the ten consecutive
trading days ending on the third trading day prior to the date on which the
Merger is consummated (the "Determination Price") is less than $27.00, each
such Company Share will be converted into the right to receive a number of
Hilton Shares equal to the Conversion Number plus an amount in cash, not to
exceed $3.00, equal to (i) the excess of $27.00 over the Determination Price,
and (b) if the Determination Price is less than $20.00, Hilton shall have the
right to elect to increase the Conversion Number to the quotient of $20.00
divided by the Determination Price, and if Hilton shall not make such an
election, the Company shall have the right to terminate the Merger Agreement.
The Merger is expected to be considered by the stockholders of the Company and
Hilton at special stockholders' meetings and consummated on or shortly after
the dates of such meetings.
 
  You have asked us whether, in our opinion, the proposed consideration to be
received by the holders of the Company Shares (other than Hilton and its
affiliates) in the Merger is fair to such holders from a financial point of
view.
 
  In arriving at the opinion set forth below, we have, among other things:
 
   1) Reviewed the Company's Annual Reports, Forms 10-K and related
      financial information for the five fiscal years ended December 31,
      1995 and the Company's Forms 10-Q and the related unaudited financial
      information for the quarterly periods ending March 31, 1996 and June
      30, 1996;
 
   2) Reviewed Hilton's Annual Reports, Forms 10-K and related financial
      information for the five fiscal years ended December 31, 1995 and
      Hilton's Forms 10-Q and the related unaudited financial information
      for the quarterly periods ending March 31, 1996 and June 30, 1996;
 
   3) Reviewed certain information, including financial forecasts, relating
      to the business, earnings, cash flow, assets and prospects of the
      Company and Hilton furnished to us by the Company and Hilton,
      respectively, as well as the cost savings and related expenses and
      synergies expected to result from the Merger, furnished to us by the
      Company;
 
   4) Conducted discussions with members of senior management of the Company
      and Hilton concerning their respective businesses and prospects;
 
 
                                      D-1
<PAGE>
 
   5) Reviewed the historical market prices and trading activity for the
      Company Shares and the Hilton Shares and compared them with those of
      certain publicly traded companies which we deemed to be reasonably
      similar to the Company and Hilton, respectively;
 
   6) Compared the results of operations of the Company and Hilton with
      those of certain companies which we deemed to be reasonably similar to
      the Company and Hilton, respectively;
 
   7) Compared the proposed financial terms of the Merger with the financial
      terms of certain other mergers and acquisitions which we deemed to be
      relevant;
 
   8) Considered the pro forma effect of the Merger on the earnings, cash
      flow, consolidated capitalization and certain financial ratios of
      Hilton;
 
   9) Reviewed the Merger Agreement;
 
  10) Reviewed the Registration Statement of Form S-4 relating to the
      issuance of Hilton Shares in the Merger, and the Joint Proxy
      Statement/Prospectus of the Company and Hilton included therein; and
 
  11) Reviewed such other financial studies and analyses and took into
      account such other matters as we deemed necessary, including our
      assessment of general economic, market and monetary conditions.
 
  In preparing our opinion, we have with your consent assumed and relied on
the accuracy and completeness of all information supplied or otherwise made
available to us by or on behalf of the Company and Hilton and all information
made publicly available by the Company and Hilton, and we have not
independently verified such information or undertaken an independent
evaluation or appraisal of any of the assets or liabilities of the Company or
Hilton or been furnished with any such evaluation or appraisal. In addition,
with your consent we have not made any physical inspection of the properties
or assets of the Company or Hilton. With respect to the financial forecasts
furnished by the Company and Hilton, we have assumed with your consent that
they have been reasonably prepared and reflect the best currently available
estimates and judgment of the management of the Company and Hilton,
respectively, as to the expected future financial performance of the Company
and Hilton, respectively, and of the management of the Company as to the cost
savings and related expenses and synergies expected to result from the Merger.
We have further assumed that the Merger will quality as a reorganization
within the meaning of Section 368(a) of the U.S. Internal Revenue Code of
1986, as amended. Our opinion is necessarily based upon market, economic,
financial and other conditions as they exist and can be evaluated as of the
date hereof.
 
  We have acted as financial advisor to the Company in connection with the
Merger and will receive a fee from the Company for our services, a significant
portion of which is contingent upon the consummation of the Merger. We have
also, in the past, provided financial advisory and financing services to the
Company and Hilton and have received fees for the rendering of such services.
In addition, in the ordinary course of our business, we may actively trade the
Company Shares and other securities of the Company, as well as securities of
Hilton, for our own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
  This opinion is addressed to the Board of Directors of the Company and does
not constitute a recommendation to any shareholder as to how such shareholder
should vote on the proposed Merger.
 
  We are not expressing any opinion herein as to the prices at which the
Hilton Shares will trade following the consummation of the Merger or the
prices at which the Company Shares or the Hilton Shares will trade between the
announcement of and the consummation of the Merger.
 
  On the basis of, and subject to the foregoing, we are of the opinion that,
as of the date hereof, the proposed consideration to be received by the
holders of the Company Shares (other than Hilton and its affiliates) in the
Merger is fair to such holders from a financial point of view.
 
                                          Very truly yours,
 
                                          MERRILL LYNCH, PIERCE, FENNER &

                            GENERAL CORPORATION LAW
                        RELATING TO DISSENTERS' RIGHTS
 
  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 (S) 228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of his 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 (S)(S) 251 (other than a merger effected pursuant to
subsection (g) of 251), 252, 254, 257, 258, 263 or 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 holders
of the surviving corporation as provided in subsection (f) of (S) 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 (S)(S) 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 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 depositary 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.
 
  (3) In the event all of the stock of a subsidiary Delaware corporation party
to a merger effected under (S) 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.
 
                                      E-1

  (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 subsections (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 his shares shall deliver to the corporation, before
the taking of the vote on the merger or consolidation, a written demand for
appraisal of his 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 his 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 (S) 228 or (S)
253 of this title, each constituent 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 constituent
corporation that 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. Any stockholder entitled to appraisal rights
may, within twenty 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 constituent 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
constituent 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 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 to be sent 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 such notice, each constituent
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 the 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 next day 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
 
                                      E-2
<PAGE>
 
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 his 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 his 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 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 his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he 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.
 
 
                                      E-3
<PAGE>
 
  (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 his 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 his 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. (Last amended by Ch. 79, L.
'95, eff. 7-1-95.)
