SECTION 2.  ADMINISTRATION

     Prior to the date of the Distribution, the Plan shall be administered by

Hilton Hotels Corporation 1996 Stock Incentive Plan.  From and after the date 
of the Distribution, the Plan shall be administered by the Stock Option 
Committee or such other committee of the Board as the Board may from time to 
time designate (the "Committee"), which shall be composed of not less than 
two members of the Board, each of whom shall be an "outside director" for 
purposes of Section 162(m)(4) of the Code and a "non-employee director" 
within the meaning of Rule 16b-3, and shall be appointed by and serve at the 
pleasure of the Board.

     The Committee shall have authority to grant Awards pursuant to the terms 
of the Plan to officers and employees of the Corporation and its subsidiaries 
and Affiliates.

     Among other things, the Committee shall have the authority, subject to 
the terms of the Plan:

     (a)    To select the officers and employees to whom Awards may from time 
to time be granted;

     (b)    Determine whether and to what extent Incentive Stock Options, 
Nonqualified Stock Options and Stock Appreciation Rights or any combination 
thereof are to be granted hereunder;


                                       3



     (c)    Determine the number of shares of Common Stock to be covered by 
each Award granted hereunder;

     (d)    Determine the terms and conditions of any Award granted hereunder 
(including, but not limited to, the option price (subject to Section 5(a)), 
any vesting condition, restriction or limitation (which may be related to the 
performance of the participant, the Corporation or any subsidiary or 
Affiliate) and any vesting acceleration or forfeiture waiver regarding any 
Award and the shares of Common Stock relating thereto, based on such factors 
as the Committee shall determine;

     (e)    Modify, amend or adjust the terms and conditions of any Award, at 
any time or from time to time; and

     (f)    Determine to what extent and under what circumstances Common 
Stock and other amounts payable with respect to an Award shall be deferred.

     The Committee shall have the authority to adopt, alter and repeal such 
administrative rules, guidelines and practices governing the Plan as it shall 
from time to time deem advisable, to interpret the terms and provisions of 
the Plan and any Award issued under the Plan (and any agreement relating 
thereto) and to otherwise supervise the administration of the Plan.

     The Committee may act only by a majority of its members then in office, 
except that the members thereof may (i) delegate to an officer of the 
Corporation the authority to make decisions pursuant to paragraphs (c), (f), 
(g), (h) and (i) of Section 5 (provided that no such delegation may be made 
that would cause Awards or other transactions under the Plan to cease to be 
exempt from Section 16(b) of the Exchange Act) and (ii) authorize any one or 
more of their number or any officer of the Corporation to execute and deliver 
documents on behalf of the Committee.

     Any determination made by the Committee or pursuant to delegated 
authority pursuant to the provisions of the Plan with respect to any Award 
shall be made in the sole discretion of the Committee or such delegate at the 
time of the grant of the Award or, unless in contravention of any express 
term of the  Plan, at any time thereafter.  All decisions made by the 
Committee or any appropriately delegated officer pursuant to the provisions 
of the Plan shall be final and binding on all persons, including the 
Corporation and Plan participants.

SECTION 3.  COMMON STOCK SUBJECT TO PLAN

     The total number of shares of Common Stock reserved and available for 
grant under the Plan shall be 45,000,000.  Of that amount, a maximum of 
9,000,000 shares of Common Stock are reserved and available for the grant of 
Special Options.  Except with respect to the Special Options and Adjusted 
Park Place Options issued pursuant to the Option Adjustment, no participant 
may be granted Awards covering in excess of 2,000,000 shares of Common Stock 
in 

                                       4



any calendar year; PROVIDED, HOWEVER, that Adjusted Park Place Options issued 
pursuant to the Option Adjustment under Section 12 hereof shall not count 
towards such limit. With respect to the Adjusted Park Place Options, no 
participant may be granted Awards in any calendar year covering in excess of 
the number of shares of Common Stock required to make the option adjustment 
with respect to such participant prescribed by Section 12(a) hereof.  With 
respect to the Special Options, the CEO may not be granted Special Options 
covering in excess of 6,000,000 shares of Common Stock in the aggregate, and 
the Chairman may not be granted Special Options covering in excess of 
3,000,000 shares of Common Stock in the aggregate. Shares subject to an Award 
under the Plan may be authorized and unissued shares or may be treasury 
shares.

     If any Stock Option (and related Stock Appreciation Right, if any) 
terminates without being exercised, shares subject to such Awards shall again 
be available for distribution in connection with Awards under the Plan.

     In the event of any change in corporate capitalization, such as a stock 
split or a corporate transaction, any merger, consolidation, separation, 
including a spin-off, or other distribution of stock or property of the 
Corporation, any reorganization (whether or not such reorganization comes 
within the definition of such term in Section 368 of the Code) or any partial 
or complete liquidation of the Corporation, the Committee or Board may make 
such substitution or adjustments in the aggregate number and kind of shares 
reserved for issuance under the Plan, in the number, kind and option price of 
shares subject to outstanding Stock Options and Stock Appreciation Rights, in 
the number and kind of shares subject to other outstanding Awards granted 
under the Plan and/or such other equitable substitution or adjustments as it 
may determine to be appropriate in its sole discretion; PROVIDED, HOWEVER, 
that the number of shares subject to any Award shall always be a whole 
number.  Such adjusted option price shall also be used to determine the 
amount payable by the Corporation upon the exercise of any Stock Appreciation 
Right associated with any Stock Option.

SECTION 4.  ELIGIBILITY

     Except with respect to the Special Options and as provided in Section 
12, full-time (30 hours per week) officers and employees of the Corporation, 
its subsidiaries and Affiliates who are responsible for or contribute to the 
management, growth and profitability of the business of the Corporation, its 
subsidiaries and Affiliates are eligible to be granted Awards under the Plan. 
Except with respect to the Special Options, no grant shall be made under  
this Plan to a director who is not an officer or a salaried employee of the 
Corporation, its subsidiaries or Affiliates.  Only the CEO and the Chairman 
are eligible to be granted Special Options under the Plan.

SECTION 5.  STOCK OPTIONS

     Stock Options may be granted alone or in addition to other Awards 
granted under the Plan and, except with respect to the Special Options, may 
be of two types:  Incentive Stock 
                                       5



Options and Nonqualified Stock Options.  Special Options may only be 
Nonqualified Stock Options.  Any Stock Option granted under the Plan shall be 
in such form as the Committee may from time to time approve.

     Except with respect to the Special Options, the Committee shall have the 
authority to grant any optionee Incentive Stock Options, Nonqualified Stock 
Options or both types of Stock Options (in each case with or without Stock 
Appreciation Rights); PROVIDED, HOWEVER, that grants hereunder are subject to 
the aggregate limit on grants to individual participants set forth in Section 
3. Incentive Stock Options may be granted only to employees of the 
Corporation and its subsidiaries (within the meaning of Section 424(f) of the 
Code).  To the extent that any Stock Option is not designated as an Incentive 
Stock Option or even if so designated does not qualify as an Incentive Stock 
Option, it shall constitute a Nonqualified Stock Option.

     Stock Options shall be evidenced by option agreements, the terms and 
provisions of which may differ.  An option agreement shall indicate on its 
face whether it is intended to be an agreement for an Incentive Stock Option 
or a Nonqualified Stock Option.  The grant of a Stock Option shall occur on 
the date a majority of the independent directors of the Corporation ratify by 
resolution the Committee's recommendation with respect to the individuals to 
be participants in any grant of a Stock Option,  the number of shares of 
Common Stock to be subject to such Stock Option to be granted to such 
individual and specifies the terms and provisions of the Stock Option.  The 
Corporation shall notify a participant of any grant of a Stock Option, and a 
written option agreement or agreements shall be duly executed and delivered 
by the Corporation to the participant.  Such agreement or agreements shall 
become effective upon execution by the Corporation and the participant.

     Anything in the Plan to the contrary notwithstanding, no term of the 
Plan relating to Incentive Stock Options shall be interpreted, amended or 
altered nor shall any discretion or authority granted under the Plan be 
exercised so as to disqualify the Plan under Section 422 of the Code or, 
without the consent of the optionee affected, to disqualify any Incentive 
Stock Option under such Section 422.

     Stock Options granted under the Plan shall be subject to the following 
terms and conditions and shall contain such additional terms and conditions 
as the Committee shall deem desirable:

     (a)    OPTION PRICE.  The option price per share of Common Stock 
purchasable under a Stock Option shall be determined by the Committee and set 
forth in the option agreement, and shall not be less than the Fair Market 
Value of the Common Stock subject to the Stock Option on the date of grant.

     (b)    OPTION TERM.  The term of each Stock Option shall be fixed by the 
Committee, but no Incentive Stock Option shall be exercisable more than ten 
years after the date the Stock Option is granted and no Nonqualified Stock 
Option shall be exercisable more than ten years and 


                                       6



one day after the date the Stock Option is granted.

     (c)    EXERCISABILITY.  Except as otherwise provided herein, Stock 
Options shall be exercisable at such time or times and subject to such terms 
and conditions as shall be determined by the Committee.  If the Committee 
provides that any Stock Option is exercisable only in installments, the 
Committee may at any time waive such installment exercise provisions, in 
whole or in part, based on such factors as the Committee may determine.  In 
addition, the Committee may at any time accelerate the exercisability of any 
Stock Option.

     (d)    METHOD OF EXERCISE.  Subject to the provisions of this Section 5, 
Stock Options may be exercised, in whole or in part, at any time during the 
option term by giving written notice of exercise to the Corporation 
specifying the number of shares of Common Stock subject to the Stock Option 
to be purchased.

     Such notice shall be accompanied by payment in full of the purchase 
price by certified or bank check or such other instrument as the Committee 
may accept. Payment, in full or in part, may also be made in the form of 
unrestricted Common Stock already owned by the optionee of the same class as 
the Common Stock subject to the Stock Option (based on the Fair Market Value 
of the Common Stock on the date the Stock Option is exercised).

     Payment for any shares subject to a Stock Option may also be made by 
delivering a properly executed exercise notice to the Corporation, together 
with a copy of irrevocable instructions to a broker to deliver  promptly to 
the Corporation the amount of sale or loan proceeds to pay the purchase 
price, and, if requested, by the amount of any federal, state, local or 
foreign withholding taxes.  To facilitate the foregoing, the Corporation may 
enter into agreements for coordinated procedures with one or more brokerage 
firms.

     No shares of Common Stock shall be issued until full payment therefor 
has been made.  An optionee shall have all of the rights of a shareholder of 
the Corporation holding the class or series of Common Stock that is subject 
to such Stock Option (including, if applicable, the right to vote the shares 
and the right to receive dividends), when the optionee has given written 
notice of exercise, has paid in full for such shares and, if requested, has 
given the representation described in Section 11(a).

     (e)    NONTRANSFERABILITY OF STOCK OPTIONS.  No Stock Option shall be 
transferable by the optionee other than (i) by will or by the laws of descent 
and distribution; or (ii) in the case of a Nonqualified Stock Option, 
pursuant to a qualified domestic relations order (as defined in the Code or 
Title I of the Employee Retirement Income Security Act of 1974, as amended, 
or the rules thereunder); or (iii) in the case of the Special Options, 
subject to such terms as the Committee deems appropriate, pursuant to a 
transfer to the optionee's spouse, children, grandchildren or parents 
("Family Members"), to trusts for the benefit of Family Members, to 
partnerships or limited liability companies in which Family Members are the 
only partners or shareholders, or to entities exempt from federal income tax 
pursuant to Section 501(c)(3) of the 
                                       7



Code.  All Stock Options shall be exercisable, subject to the terms of this 
Plan, during the optionee's lifetime, only by the optionee or by the guardian 
or legal representative of the optionee or, in the case of a Nonqualified 
Stock Option, its alternative payee pursuant to such qualified domestic 
relations order, it being understood that the terms "holder" and "optionee" 
include the guardian and legal representative of the optionee named in the 
option agreement and any person to whom an option is transferred by will or 
the laws of descent and distribution or, in the case of a Nonqualified Stock 
Option, pursuant to a qualified domestic relations order.

     (f)    TERMINATION BY DEATH.  Unless otherwise determined by the 
Committee, if an optionee's employment terminates by reason of death, any 
Stock Option held by such optionee may thereafter  be exercised, to the 
extent then exercisable, or on such accelerated basis as the Committee may 
determine, for a period of one year (or such other period as the Committee 
may specify in the option agreement) from the date of such death or until the 
expiration of the stated term of such Stock Option, whichever period is the 
shorter.

     (g)    TERMINATION BY REASON OF DISABILITY.  Unless otherwise determined 
by the Committee, if an optionee's employment terminates by reason of 
Disability, any Stock Option held by such optionee may thereafter be 
exercised by the optionee, to the extent it was exercisable at the time of 
termination, or on such accelerated basis as the Committee may determine, for 
a period of six months (or such other period as the Committee may specify in 
the option agreement) from the date of such termination of employment or 
until the expiration of the stated term of such Stock Option, whichever 
period is the shorter; PROVIDED, HOWEVER, that if the optionee dies within 
such period, any unexercised Stock Option held by such optionee shall, 
notwithstanding the expiration of such period, continue to be exercisable to 
the extent to which it was exercisable at the time of death for a period of 
12 months from the date of such death or until the expiration of the stated 
term of such Stock Option, whichever period is the shorter.  In the event of 
termination of employment by reason of Disability, if an Incentive Stock 
Option is exercised after the expiration of the exercise periods that apply 
for purposes of Section 422 of the Code, such Stock Option will thereafter be 
treated as a Nonqualified Stock Option.

     (h)    TERMINATION BY REASON OF RETIREMENT.  Unless otherwise determined 
by the Committee, if an optionee's employment terminates by reason of 
Retirement, any Stock Option held by such optionee may thereafter be 
exercised by the optionee, to the extent it was exercisable at the time of 
such Retirement, or on such accelerated basis as the Committee may determine, 
for a period of two years (or such other period as the Committee may specify 
in the option agreement) from the date of such termination of employment or 
until the expiration of the stated term of such Stock Option, whichever 
period is the shorter; PROVIDED, HOWEVER, that if the optionee dies within 
such period any unexercised Stock Option held by such optionee shall, 
notwithstanding the expiration of such period, continue to be exercisable to 
the extent to which it was exercisable at the time of death for a period of 
12 months from the date of such death or until the expiration of the stated 
term of such Stock Option, whichever period is the shorter.  In the event of 
termination of employment by reason of Retirement, if an Incentive Stock 
Option is exercised after the expiration of the exercise periods that apply 
for purposes of Section 422 of the 
                                       8



Code, such Stock Option will thereafter be treated as a Nonqualified Stock 
Option.

     (i)    OTHER TERMINATION.  Unless otherwise determined by the Committee: 
(A) if an optionee incurs a Termination of Employment, all Stock Options held 
by such optionee shall thereupon terminate; and (B) if an optionee incurs a 
Termination of Employment for any reason other than death, Disability or 
Retirement, any Stock Option held by such optionee, to the extent then 
exercisable, or on such accelerated basis as the Committee may determine, may 
be exercised for the lesser of three months from the date of such Termination 
of Employment or the balance of such Stock Option's term;  PROVIDED, HOWEVER, 
that if the optionee dies within such three-month period, any unexercised 
Stock Option held by such optionee shall, notwithstanding the expiration of 
such three-month period, continue to be exercisable to the extent to which it 
was exercisable at the time of death for a period of 12 months from the date 
of such death or until the expiration of the stated term of such Stock 
Option, whichever period is the shorter.  Notwithstanding the foregoing, if 
an optionee incurs a Termination of Employment at or after a Change in 
Control (as defined Section 7(b)), other than by reason of death, Disability 
or Retirement, any Stock Option held by such optionee shall be exercisable 
for the lesser of (1) six months and one day from the date of such 
Termination of Employment, and (2) the balance of such Stock Option's term.  
In the event of Termination of Employment, if an Incentive Stock Option is 
exercised after the expiration of the exercise periods that apply for 
purposes of Section 422 of the Code, such Stock Option will thereafter be 
treated as a Nonqualified Stock Option.

     (j)    CHANGE IN CONTROL CASH-OUT.  Notwithstanding any other provision 
of the Plan, during the 60-day period from and after a Change in Control (the 
"Exercise Period"), unless the Committee shall determine otherwise at the 
time of grant, an optionee shall have the right, whether or not the Stock 
Option is fully exercisable and in lieu of the payment of the exercise price 
for the shares of Common Stock being purchased under the Stock Option and by 
giving notice to the Corporation, to elect (within the Exercise Period) to 
surrender all or part of the Stock Option to the Corporation and to receive 
cash, within 30 days of such notice, in an amount equal to the amount by 
which the Change in Control Price per share of Common Stock on the date of 
such election shall exceed the exercise price per share of Common Stock under 
the Stock Option (the "Spread") multiplied by the number of shares of Common 
Stock granted under the Stock Option as to which the right granted under this 
Section 5(j) shall have been exercised; PROVIDED, HOWEVER, that if the Change 
in Control is within six months of the date of grant of a particular Stock 
Option held by an optionee who is an officer or director of the Corporation 
and is subject to Section 16(b) of the Exchange Act no such election shall be 
made by such optionee with respect to such Stock Option prior to six months 
from the date of grant.  However, if the end of such 60-day period from and 
after a Change in Control is within six months of the date of grant of a 
Stock Option held by an optionee who is an officer or director of the 
Corporation and is subject to Section 16(b) of the Exchange Act, such Stock 
Option shall be cancelled in exchange for a cash payment to the optionee, 
effected on the day which is six months and one day after the date of grant 
of such Option, equal to the Spread multiplied by the number of shares of 
Common Stock granted under the Stock Option. Notwithstanding the foregoing, 
if any right granted pursuant to this Section 5(j) would make a Change in 
Control transaction ineligible for 
                                       9



pooling of interests accounting under APB No. 16 that but for this Section 
5(j) would otherwise be eligible for such accounting treatment, the Committee 
shall have the ability to substitute the cash payable pursuant to this 
Section 5(j) with Stock with a Fair Market Value equal to the cash that would 
otherwise be payable hereunder.

SECTION 6.  STOCK APPRECIATION RIGHTS

     (a)    GRANT AND EXERCISE.  Stock Appreciation Rights may be granted in 
conjunction with all or part of any Stock Option granted under the Plan.  In 
the case of a Nonqualified Stock Option, such rights may be granted either at 
or after the time of grant of such Stock Option.  In the case of an Incentive 
Stock Option, such rights may be granted only at the time of grant of such 
Stock Option.  A Stock Appreciation Right shall  terminate and no longer be 
exercisable upon the termination or exercise of the related Stock Option.

     A Stock Appreciation Right may be exercised by an optionee in accordance 
with Section 6(b) by surrendering the applicable portion of the related Stock 
Option in accordance with procedures established by the Committee.  Upon such 
exercise and surrender, the optionee shall be entitled to receive an amount 
determined in the manner prescribed in Section 6(b).  Stock Options which 
have been so surrendered shall no longer be exercisable to the extent the 
related Stock Appreciation Rights have been exercised.

     (b)    TERMS AND CONDITIONS.  Stock Appreciation Rights shall be subject 
to such terms and conditions as shall be determined by the Committee, 
including the following:

            (i)    Stock Appreciation Rights shall be exercisable only at 
     such time or times and to the extent that the Stock Options to which 
     they relate are exercisable in accordance with the provisions of Section 
     5 and this Section 6; PROVIDED, HOWEVER, that a Stock Appreciation Right 
     shall not be exercisable during the first six months of its term by an 
     optionee who is actually or potentially subject to Section 16(b) of the 
     Exchange Act, except that this limitation shall not apply in the event 
     of death or Disability of the optionee prior to the expiration of the 
     six-month period.

            (ii)   Upon the exercise of a Stock Appreciation Right, an 
     optionee shall be entitled to receive an amount in cash, shares of 
     Common Stock or both, equal in value to the excess of the Fair Market 
     Value of one share of Common Stock over the option price per share 
     specified in the related Stock Option multiplied by the number of shares 
     in respect of which the Stock Appreciation Right shall have been 
     exercised, with the Committee having the right to determine the form of 
     payment.

            (iii)  Stock Appreciation Rights shall be transferable only to 
     permitted transferees of the underlying Stock Option in accordance with 
     Section 5(e).

            (iv)   Upon the exercise of a Stock Appreciation Right, the Stock 
     Option or part 
                                       10



     thereof to which such Stock Appreciation Right is related shall be 
     deemed to have been exercised for the purpose of the limitation set 
     forth in Section 3 on the number of shares of Common Stock to be issued 
     under the Plan, but only to the extent of the number of shares covered 
     by the Stock Appreciation Right at the time of exercise based on the 
     value of the Stock Appreciation Right at such time.

SECTION 7.  CHANGE IN CONTROL PROVISIONS

     (a)    IMPACT OF EVENT.  Notwithstanding any other provision of the Plan to
the contrary, in the event of a Change in Control, any Stock Options and Stock
Appreciation Rights outstanding as of the date such Change in Control is

     also members of the Incumbent Board (or deemed to be such pursuant to 
     this proviso) shall be considered as though such individual were a 
     member of the Incumbent Board; but, PROVIDED FURTHER, that any such 
     individual  whose initial assumption of office occurs as a result of 
     either an actual or threatened election contest (as such terms are used 
     in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or

     entitled to vote generally in the election of directors, as the case may

     transaction owns the Corporation or all or substantially all of the
     Corporation's assets either directly or through one or more subsidiaries)

discretion of the Board.

SECTION 8.  TERM, AMENDMENT AND TERMINATION

     The Plan will terminate ten years after the effective date of the Plan. 
Under the Plan, Awards outstanding as of such date shall not be affected or 
impaired by the termination of the Plan.

     The Board may amend, alter, or discontinue the Plan, but no amendment, 
alteration or discontinuation shall be made which would (i) impair the rights 
of an optionee under a Stock Option or a recipient of a Stock Appreciation 
Right theretofore granted without the optionee's or recipient's consent, 
except such an amendment made to cause the Plan to qualify for the exemption 
provided by Rule 16b-3, or (ii) disqualify the Plan from the exemption 
provided by Rule 16b-3.  In addition, no such amendment shall be made without 
the approval of the Corporation's shareholders to the extent such approval is 
required by law or agreement.

     The Committee may amend the terms of any Stock Option or other Award 
theretofore granted, prospectively or retroactively, but no such amendment 
shall impair the rights of any holder without the holder's consent except 
such an amendment made to cause the Plan or Award to qualify for the 
exemption provided by Rule 16b-3.

     Subject to the above provisions, the Board shall have authority to amend 
the Plan to take into account changes in law and tax and accounting rules as 
well as other developments, and to grant Awards which qualify for beneficial 
treatment under such rules without stockholder approval.

SECTION 9.  UNFUNDED STATUS OF PLAN

     It is presently intended that the Plan constitute an "unfunded" plan for 
incentive and deferred compensation.  The Committee may authorize the 
creation of trusts or other arrange-
                                       13



ments to meet the obligations created under the Plan to deliver Common Stock 
or make payments; PROVIDED, HOWEVER, that unless the Committee otherwise 
determines, the existence of such trusts or other arrangements is consistent 
with the "unfunded" status of the Plan.

SECTION 10. GENERAL PROVISIONS

     (a)    The Committee may require each person purchasing or receiving 
shares pursuant to an Award to represent to and agree with the Corporation in 
writing that such person is acquiring the shares without a view to the 
distribution thereof.  The certificates for such shares may include any 
legend which the Committee deems appropriate to reflect any restrictions on 
transfer.

     Notwithstanding any other provision of the Plan or agreements made 
pursuant thereto, the Corporation shall not be required to issue or deliver 
any certificate or certificates for shares of Common Stock under the Plan 
prior to fulfillment of all of the following conditions:

            (1)    Listing or approval for listing upon notice of issuance, of
     such shares on the New York Stock Exchange, Inc., or such other securities
     exchange as may at the time be the principal market for the Common Stock;

            (2)    Any registration or other qualification of such shares of the
     Corporation under any state or federal law or regulation, or the
     maintaining in effect of any such registration or other qualification which
     the Committee shall, in its absolute discretion upon the advice of counsel,
     deem necessary or advisable; and

            (3)    Obtaining any other consent, approval, or permit from any
     state or federal governmental agency which the Committee shall, in its
     absolute discretion after receiving the advice of counsel, determine to be
     necessary or advisable.

     (b)    Nothing contained in the Plan shall prevent the Corporation or 
any subsidiary or Affiliate from adopting other or additional compensation 
arrangements for its employees.

     (c)    Adoption of the Plan shall not confer upon any employee any right 
to continued employment, nor shall it interfere in any way with the right of 
the Corporation or any subsidiary or Affiliate to terminate the employment of 
any employee at any time.

     (d)    No later than the date as of which an amount first becomes 
includible in the gross income of the participant for federal income tax 
purposes with respect to any Award under the Plan, the participant shall pay 
to the Corporation, or make arrangements satisfactory to the Committee 
regarding the payment of, any federal, state, local or foreign taxes of any 
kind required by law to be withheld with respect to such amount.  Unless 
otherwise determined by the Corporation, withholding obligations may be 
settled with Common Stock, including Common Stock that is part of the Award 
that gives rise to the withholding requirement.  The obligations of 

                                       14



the Corporation under the Plan shall be conditional on such payment or 
arrangements, and the Corporation and its Affiliates shall, to the extent 
permitted by law, have the right to deduct any such taxes from any payment 
otherwise due to the participant.  The Committee may establish such 
procedures as it deems appropriate, including making irrevocable elections, 
for the settlement of withholding obligations with Common Stock.

     (e)    The Committee shall establish such procedures as it deems 
appropriate for a participant to designate a beneficiary to whom any amounts 
payable in the event of the participant's death are to be paid or by whom any 
rights of the participant, after the participant's death, may be exercised.

     (f)    In the case of a grant of an Award to any employee of a 
subsidiary of the Corporation, the Corporation may, if the  Committee so 
directs, issue or transfer the shares of Common Stock, if any, covered by the 
Award to the subsidiary, for such lawful consideration as the Committee may 
specify, upon the condition or understanding that the subsidiary will 
transfer the shares of Common Stock to the employee in accordance with the 
terms of the Award specified by the Committee pursuant to the provisions of 
the Plan.

     (g)    The Plan and all Awards made and actions taken thereunder shall 
be governed by and construed in accordance with the laws of the State of 
Delaware, without reference to principles of conflict of laws.

SECTION 11. EFFECTIVE DATE OF PLAN

     The Plan shall be effective as of July 9, 1998, provided that it is 
approved by at least a majority of the shares voted of Hilton Common Stock at 
the special meeting of Hilton stockholders with respect to the Distribution 
and other related matters.

                                       15




SECTION 12. PROVISIONS REGARDING THE DISTRIBUTION

     (a)    Concurrently with the Distribution, the Corporation and Hilton 
are entering into that certain Employee Benefits and Other Employment Matters 
Allocation Agreement, dated as of the date of the Distribution (the "Benefits 
Allocation Agreement"), which provides for the Corporation and Hilton to 
allocate the responsibilities with respect to certain matters relating to 
employees and employee compensation, benefits, labor and other employment 
matters.  Concurrently with the Distribution and pursuant to the terms of the 
Benefits Allocation Agreement, all outstanding options to purchase Hilton 
Common Stock (each, a "Hilton Option"), other than Hilton Options held by 
Arthur M. Goldberg, shall be adjusted (the "Option Adjustment") to represent 
options to purchase an equivalent number of shares of Hilton Common Stock 
(each adjusted option to purchase Hilton Common Stock, an "Adjusted Hilton 
Option") and shares of the Corporation's Common Stock (each adjusted option 
to purchase the Corporation's Common Stock, an "Adjusted Park Place Option"). 
 Pursuant to the Option Adjustment, the intrinsic value of the Hilton Options 
immediately prior to the Distribution shall be preserved immediately after 
the Distribution, and the exercise price of the Hilton Options shall be 
allocated between the Adjusted Hilton Options and the Adjusted Park Place 
Options based upon the relative values of Hilton Common Stock and the 
Corporation's Common Stock on the date of the Distribution, all as determined 
by Hilton.  Concurrently with the Distribution and pursuant to the terms of 
the Benefits Allocation Agreement, all outstanding Hilton Options held by 
Arthur M. Goldberg shall be adjusted to represent Adjusted Park Place 
Options.  Pursuant to such adjustment, the intrinsic value of Mr. Goldberg's 
outstanding Hilton Options immediately prior to the Distribution shall be 
preserved immediately after the Distribution, and the number of shares 
subject to and the exercise price of such options shall be adjusted based on 
the relative values of the Hilton Common Stock and the Corporation's Common 
Stock on the date of the Distribution, all as determined by Hilton.

     (b)    Following the date of the Option Adjustment, all Adjusted Park 
Place Options which are issued as a result of Hilton Options granted under 
any of the Hilton 1984 Stock Option and Stock Appreciation Rights Plan, the 
Hilton 1990 Stock Option and Stock Appreciation Rights Plan, the Hilton 1996 
Stock Incentive Plan, or the Hilton 1996 Chief Executive Stock Incentive Plan 
shall be subject to the terms of this Plan and the applicable option 
agreement, and all Adjusted Hilton Options shall be subject to the terms of 
the applicable Hilton stock option plan and any applicable option agreement.

     (c)    For purposes of this Plan, with respect to Adjusted Park Place 
Options held by Hilton Individuals (as defined in the Benefits Allocation 
Agreement) as a result of the Option Adjustment, references to employment or 
termination of employment in this Plan and in the applicable option agreement 
shall be deemed to refer to employment by or termination of employment with 
Hilton and its subsidiaries or affiliates.  Notwithstanding the foregoing, 
with respect to Adjusted Park Place Options held by the Chairman as a result 
of the Option Adjustment, references to employment or termination of 
employment in this Plan and in the applicable option agreement shall be 
deemed to refer to employment by or termination of 

                                       16



employment with the Corporation and Hilton and their subsidiaries or 
affiliates.  For purposes of this Plan, no termination of the Chairman's 
employment shall be deemed to have occurred until such time as the Chairman's 
employment with both the Corporation and Hilton (and their subsidiaries or 
affiliates) has been terminated.

SECTION 13. SPECIAL OPTIONS

     The Committee shall have the authority to grant Special Options to the 
CEO and/or the Chairman on such terms and conditions as it shall determine in 
its sole discretion.  The terms and conditions of such Special Options 
granted to the Corporation's initial CEO shall be set forth in the Employment 
Agreement, and the terms and conditions of such Special Options granted to 
the Corporation's initial Chairman shall be set forth in the Chairman 
Agreement.  To the extent that certain terms and conditions of the Special 
Options are not set forth in the Employment Agreement or the Chairman 
Agreement, as the case may be, the terms of the Plan shall apply to the 
Special Options.
