SECTION 4. ELIGIBILITY Except as provided in Section 10, Independent Directors are eligible to be granted Stock Options under the Plan. SECTION 5. STOCK OPTIONS No Stock Option granted under the Plan shall constitute an "incentive stock option" under Section 422 of the Code. Any Stock Option granted under the Plan shall be in such form as the Board may from time to time approve. During the term of the Plan, each person who is an Independent Director as of the effective date of the approval of the amended Plan shall be automatically granted a Stock Option to purchase fifty thousand (50,000) shares of common stock (subject to adjustment as provided herein) on such effective date. During the term of the Plan, each person who is initially elected to the Board as an Independent Director after the effective date of the approval of the amended Plan, shall be automatically granted a Stock Option to purchase fifty thousand (50,000) shares of common stock (subject to adjustment as provided herein) on the date of such initial election. 4 Stock Options shall be evidenced by option agreements, the terms and provisions of which may differ. The grant of a Stock Option shall occur on the dates specified above. 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. 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 Board shall deem desirable: (a) OPTION PRICE. The option price per share of common stock purchasable under a Stock Option shall equal 100% of 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 10 years from the date such Stock Option is granted, without variation or acceleration hereunder, but subject to paragraphs (f), (g), (h) and (i) of this Section 5, and no Stock Option shall be exercisable more than ten years after the date the Stock Option is granted. (c) VESTING AND EXERCISABILITY. Except as otherwise provided herein, each Stock Option to purchase 50,000 shares shall become fully vested and exercisable over a four-year period from and after the date on which such Stock Option is granted, as follows: 20% on the date of the grant, 20% on the first anniversary of the grant, 20% on the second anniversary of the grant, 20% on the third anniversary of the grant, and 20% on the fourth anniversary of the grant, for such period as the person remains in office as an Independent Director. (D) METHOD OF EXERCISE. Subject to the provisions of this Section 5, vested 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 Board 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). 5 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 turns. 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 8(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) 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) whether directly or indirectly or by means of a trust or partnership or otherwise, under the applicable option agreement. 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 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 pursuant to a qualified domestic relations order. (f) TERMINATION BY DEATH. Unless otherwise determined by the Board, if an optionee's directorship terminates by reason of death, any Stock Option held by such optionee may thereafter be exercised, to the extent then exercisable, for a period of one year (or such other period as the Board 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 Board, if an optionee's directorship 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, for a period of one year (or such other period as the Board may specify in the option agreement) from the date of such termination of directorship 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. (h) TERMINATION BY REASON OF RETIREMENT. Unless otherwise determined by the Board, if an optionee's directorship 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, for a period of two years (or such other period as the Board may specify in the option agreement) from the date of such termination of directorship 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. (i) OTHER TERMINATION. Unless otherwise determined by the Board: (A) if an optionee incurs a Termination of Directorship, other than by death, Disability or Retirement, all Stock Options held by 6 such optionee shall thereupon terminate; and (B) if an optionee incurs a Termination of Directorship for any reason other than death, Disability or Retirement, any Stock Option held by such optionee, to the extent then exercisable, may be exercised, for the lesser of three months from the date of such Termination of Directorship 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 Directorship at or after a Change in Control, 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 Directorship, and (2) the balance of such Stock Option's term. (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 Board 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 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 and is subject to Section 16(b) of the Exchange Act, such Stock Option shall be canceled 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 pooling of interests accounting under APB No. 16 that but for this Section 5(j) would otherwise be eligible for such accounting treatment, the Board 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. TERM, AMENDMENT AND TERMINATION The Plan will terminate 10 years after the effective date of the Plan. Under the Plan, Stock Options 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 theretofore granted without the optionee'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 stockholders (i) if such amendment would increase the limit imposed under Section 3 on the maximum number of shares of common stock reserved and available for grant under the Plan, or (ii) to the extent such approval is required by law or agreement. The Board may amend the terms of any Stock Option theretofore granted, prospectively or retroactively, but no such amendment shall impair the rights of any holder without the holder's consent 7 except such an amendment made to cause the Plan or Stock Option 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 Stock Options which qualify for beneficial treatment under such rules without stockholder approval. SECTION 7. UNFUNDED STATUS OF PLAN It is presently intended that the Plan constitute an "unfunded" plan for incentive and deferred compensation. The Board may authorize the creation of trusts or other arrangements to meet the obligations created under the Plan to deliver common stock or make payments; provided, however, that unless the Board otherwise determines, the existence of such trusts or other arrangements is consistent with the "unfunded" status of the Plan. SECTION 8. GENERAL PROVISIONS (a) The Board may require each person purchasing or receiving shares pursuant to a Stock Option 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 Board 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: (i) 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; (ii) 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 Board shall, in its absolute discretion upon the advice of counsel, deem necessary or advisable; and (iii) Obtaining any other consent, approval, or permit from any state or Federal governmental agency which the Board 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 or Directors. (c) Adoption of the Plan shall not confer upon any Independent Director any right to continue to serve as a Director, nor shall it interfere in any way with the right of the Corporation to terminate the directorship of any Independent Director 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 Stock Option under the Plan, the participant shall pay to the Corporation, or make arrangements satisfactory to the Board 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. The obligations of 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 Board may establish such procedures as it deems appropriate, including making irrevocable elections, for the settlement of withholding obligations with common stock. 8 (e) The Board 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) The Plan and all Stock Options granted 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 9. EFFECTIVE DATE OF PLAN The Plan shall be effective on December 31, 1998. The amendments to this Plan shall be effective as of the date of the stockholder meeting approving the amendments. SECTION 10. 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 granted under the Hilton 1997 Independent Director Stock Option Plan (each, a "Hilton Director Option") 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 Director Options immediately prior to the Distribution shall be preserved immediately after the Distribution, and the exercise price of the Hilton Director 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. (b) Following the date of the Option Adjustment, all Adjusted Park Place Options which were issued as a result of Hilton Director Options shall be subject to the terms of this Plan and the applicable option agreement and all Adjusted Hilton Options which were issued as a result of Hilton Director Options shall be subject to the terms of the Hilton 1997 Independent Director Stock Option Plan and any applicable option agreement. (c) For purposes of this Plan, with respect to Adjusted Park Place Options held by members of the Board of Directors of Hilton (the "Hilton Board") as a result of the Option Adjustment, references to directorship or termination of directorship in this Plan and in the applicable option agreement shall be deemed to refer to directorship or termination of directorship on the Hilton Board. 9
