EXHIBIT 10.21 EMPLOYMENT AGREEMENT AGREEMENT by and between Hilton Hotels Corporation, a Delaware corporation (the "Company"), and Stephen F. Bollenbach (the "Executive"), dated as of the 1st day of February, 1996. WHEREAS, the Board of Directors of the Company (the "Board") has determined that it is in the best interests of the Company and its shareholders to employ the Executive as President and Chief Executive Officer, and the Executive desires to serve in that capacity; NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 1. EMPLOYMENT PERIOD. The Company shall employ the Executive, and the Executive shall serve the Company, on the terms and conditions set forth in this Agreement, for the period beginning on the date first above appearing (the "Commencement Date") and ending on the fifth anniversary of the Commencement Date (the "Employment Period"). 2. POSITION AND DUTIES. (a) During the Employment Period, the Executive shall be employed as the President and Chief Executive Officer and commencing with the Company's 1996 annual meeting of shareholders, shall be a member of the Board of Directors of the Company. In such capacity, the Executive shall report to the Board through the Chairman of the Board. During the Employment Period, no executive of the Company other than the Executive shall have a direct reporting relationship with the Chairman of the Board. During the Employment Period, the Executive shall have authority to make all operating decisions, plan the strategic direction of the Company, and hire, promote and terminate employment of all personnel, subject to the direction of the Board. During the Employment Period, the Executive shall have such reasonable and customary powers as are generally associated with the positions of President and Chief Executive Officer, including, without limitation, authority to expend capital resources of the Company and shall have, subject to the direction of the Board, authority to fill all management positions including, without limitation, the position of Chief Financial Officer, which position shall entitle its holder to an annual base salary of up to approximately $450,000, an annual target incentive bonus in the range of up to 50 to 70 per cent of base salary, and a grant of stock options under the Company's stock incentive plans to purchase up to 50,000 shares of the Company's common stock. (b) If, during the Employment Period, Barron Hilton shall cease to serve as Chairman of the Board for any reason, the Executive thereupon shall become Chairman of the Board in addition to President and Chief Executive Officer and shall, as Chairman, report directly to the Board. -2- (c) During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive shall devote principal attention and time during normal business hours to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive under this Agreement, use the Executive's reasonable best efforts to carry out such responsibilities faithfully and efficiently. It shall not be considered a violation of the foregoing for the Executive to (A) serve on corporate, civic or charitable boards or committees (excluding those which would create a conflict of interest), (B) deliver lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not materially interfere with the performance of the Executive's responsibilities as an employee of the Company in accordance with this Agreement. (d) The Executive's services shall be performed primarily at the Company's Headquarters in Beverly Hills, California. (e) From time to time during the Employment Period, the Personnel and Compensation Committee of the Company's Board of Directors (the "P&C Committee") shall consider whether, in its good faith judgment, the Executive is -3- endowed with authority comparable to that typically granted to chief executive officers of publicly held companies ("Appropriate Authority"). If the P&C Committee shall determine that the Executive does not have Appropriate Authority and such determination is not cured within 90 days after the other members of the Board have received notice of such determination, the Executive may, but need not, terminate his employment with the Company, and such termination shall be a termination for Good Reason for all purposes under this Agreement. 3. COMPENSATION. (a) BASE SALARY. During the Employment Period, the Executive shall receive an annual base salary ("Annual Base Salary") of $540,000, payable in accordance with the regular payroll practices of the Company. During the Employment Period, the Annual Base Salary shall be reviewed for possible increase at least annually, with any increase being at the sole discretion of the Board or the P&C Committee. Any increase in the Annual Base Salary shall not limit or reduce any other obligation of the Company under this Agreement. The Annual Base Salary shall not be reduced after any such increase, and the term "Annual Base Salary" shall thereafter refer to the Annual Base Salary as so increased. -4- (b) ANNUAL BONUS. In addition to the Annual Base Salary, the Executive shall be eligible to receive, for each fiscal year or portion of a fiscal year ending during the Employment Period, an annual bonus (the "Annual Bonus") (either pursuant to the Company's annual incentive plan or otherwise) with an annual target award opportunity of up to 100 per cent of Annual Base Salary provided that the Executive shall receive a minimum guaranteed award for 1996 in an amount equal to the remainder of $1,000,000 minus the amount of Annual Base Salary actually paid to the Executive in 1996. Each Annual Bonus shall be paid in a single cash lump sum no later than 90 days after the end of the fiscal year or portion thereof for which the Annual Bonus is awarded, unless the Executive elects in writing, before the beginning of the fiscal year for which the Annual Bonus is to be awarded (or at such later date as may be permitted under the Company's generally applicable policies or procedures), to defer receipt of the Annual Bonus. (c) OTHER BENEFITS. During the Employment Period: (i) the Executive shall be entitled to participate in all incentive, savings and retirement plans, practices, policies and programs of the Company to at least the same extent as other senior executives of the Company, provided that in determining the Executive's participation in such plans the Incentive Options granted hereunder shall be taken -5- into account; and (ii) the Executive and/or the Executive's family, as the case may be, shall be eligible for participation in, and shall receive all benefits under, all welfare benefit plans, practices, policies and programs provided by the Company (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life insurance, group life insurance, accidental death and travel accident insurance plans and programs) to at least the same extent as other senior executives of the Company. (d) EXPENSES. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive in carrying out the Executive's duties under this Agreement, provided that the Executive complies with the generally applicable policies, practices and procedures of the Company for submission of expense reports, receipts, or similar documentation of such expenses. (e) FRINGE BENEFITS. During the Employment Period, the Executive shall be entitled to fringe benefits and perquisites in accordance with the most favorable plans, practices, programs and policies of the Company as in effect at the time with respect to other senior executives of the Company, including, without limitation, the use of an automobile and payment of related expenses; reasonable travel on -6- the Company's aircraft; and first-class travel accommodations on all commercial carriers for travel related to the business of the Company.

Avansino, Jr. during Mr. Avansino's tenure as President and Chief Operating Officer of the Company, and to secretarial and other assistance, at least equal to the most favorable of such as provided with respect to other senior executives of the Company. Without limiting the generality of the foregoing, the Executive shall at all times have a personal secretary and a personal assistant. (g) VACATION. During the Employment Period, the Executive shall be entitled to four weeks of paid vacation annually. (h) STOCK OPTIONS: (i) The Executive was granted non-statutory stock options under the Company's 1996 Chief Executive Stock Incentive Plan (the "Stock Plan") covering 1,500,000 shares of the Company's common stock with an exercise price equal to $74.6875 per share (the "Incentive Options"). The Company shall register with the Securities and Exchange Commission under the Securities Act of 1933, as amended, the shares issuable upon the exercise of the -7- Incentive Options not later than January 1, 1997. No Incentive Option shall be exercisable more than 5 years after the date the Incentive Option is granted. The Incentive Options shall vest and become exercisable according to the following schedule: (1) 25%: on January 1, 1997. (2) 50%: on January 1, 1998. (3) 75%: on January 1, 1999.

Notwithstanding the foregoing, in the event that the Executive receives the Substitute Payment, the Incentive Option shall cease to be exercisable at the end of the fifth trading day after the Executive receives the Substitute Payment. (iii) Notwithstanding the foregoing, the Incentive Options shall terminate if the Plan is not approved by a majority of the shares of common stock of the Company voting at its annual meeting scheduled to be held on May 6, 1996. The Company will use its reasonable best efforts to secure such shareholder approval. If such approval is not obtained and unless the Company elects to implement a similar award without obtaining such approval, this Agreement and the Executive's employment with the Company shall terminate immediately, the Company shall pay to the Executive $10,000,000, and the Company thereafter shall have no further -9- obligations under this Agreement and the Executive's sole obligations shall be those set forth in Section 9 hereof. (i) SUBSTITUTE PAYMENT. (1) Notwithstanding any other provision hereof, upon the earlier to occur of: (A) a Triggering Event; or (B) a termination of employment by the Executive without Good Reason on or after the third anniversary of the Commencement Date, the Executive shall be entitled to receive a payment (the "Substitute Payment") not to exceed $20,000,000, equal to the excess, if any, of (x) $20,000,000 over (y) the sum of A plus B, where "A" equals the product of (i) the excess of the Fair Market Value of the Company's Common Stock on the date the Executive becomes entitled to receive the Substitute Payment over the Fair Market Value of the Company's Common Stock on the Commencement Date times (ii) 1,500,000 less the sum of (x) the number of shares of Company common stock acquired upon exercise and disposal of which are referred to in clause (i) of B below, (y) the number of shares of Company common stock acquired upon exercise and referred to in clause (ii) of B below and (z) the number of shares of the Company's Common Stock subject to the Incentive Option that are not vested following the event giving rise to the right to the Substitute Payment; and "B" equals the sum of (i) the aggregate gain, if any, realized by the Executive on the disposition prior to the date the Executive becomes entitled to receive the Substitute Payment of shares of the Company's Common Stock acquired via exercise of Incentive Options, and (ii) the excess, if any, of the Fair Market Value of any shares of the Company's common stock held by the Executive on the date -10- the Executive becomes entitled to the Substitute Payment acquired via the exercise of Incentive Options, over the price paid for those shares. (2) The Executive may elect to receive the Substitute Payment either in cash or the Company's common stock based on the Fair Market Value of such stock on the date the Executive becomes entitled to receive the Substitute Payment, provided, however, that the Company shall have the right to require that the Substitute Payment be made in shares of the Company's common stock if, in the opinion of the Company's accountants, payment of the Substitute Payment in cash would make any transaction ineligible for pooling of interests accounting under APB No. 16 that but for payment of the Substitute Payment in cash would otherwise be eligible for such accounting treatment. The Company shall register any shares issuable in respect of the Substitute Payment with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended. (3) The Executive may assign the right to receive the Substitute Payment to a family partnership designated by the Executive. -11- (4) If the Executive becomes entitled to receive the Substitute Payment because the Executive's employment terminates because of death or Disability, then subparagraphs (1), (2) and (3), above, shall apply with "the Executive or his estate or legal representative" substituted for "the Executive" and "$10,000,000" substituted for "$20,000,000." (j) LOAN. On the Commencement Date, the Company will lend the Executive $5,000,000 (the "Loan"). The Loan will be full recourse and will be due and payable on the earlier of (x) January 1, 2000, and (y) the termination of the Executive's employment, and will bear interest, compounded semi-annually, at 100 per cent of the applicable federal rate provided for in Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended. The Loan shall be prepayable by the Executive at any time without penalty. The Loan will be secured by a security interest which the Executive will grant the Company in (i) the net number of shares of the Company's common stock (after the payment of any associated tax liability) acquired by the Executive via exercise of Incentive Options, (ii) the Substitute Payment and (iii) the payment, if any, referred to in Section 3(h)(iii), provided that the Company shall release such security interest from any shares as to which the Executive gives the Company notice of his intent sell, so long as the -12- Executive makes arrangements reasonably satisfactory to the Company to apply the net after tax proceeds of such sale to repay such Loan. The Company, in lieu of receiving the security interest described in the preceding sentence, may elect to withhold a portion of the Substitute Payment equal to the total outstanding amount due under the Loan as of the date the Executive becomes entitled to receive the Substitute Payment, such withheld amount, if any, to be in full satisfaction of the Executive's repayment obligations under the terms of the Loan. 4.

A termination of the Executive's employment by the Company for Disability shall be communicated to the Executive by written notice, and shall be effective on the 30th day after receipt of such notice by the Executive (the "Disability Effective Date"), unless the Executive returns to full-time performance of the Executive's duties before the Disability Effective Date. (b) BY THE COMPANY. (i) The Company may terminate the Executive's employment during the Employment Period for Cause or without Cause. "Cause" means: A. the willful and continued failure of the Executive substantially to perform the Executive's duties under this Agreement (other than as a result of physical or mental illness or injury), after the Board delivers to the Executive a written demand for substantial performance that specifically identifies the manner in which the Board believes that the Executive has not substantially performed the Executive's duties; -14- B. illegal conduct or gross misconduct by the Executive, in either case that is willful and results in material and demonstrable damage to the business or reputation of the Company; or C. a breach of the covanants or representations contained in Section 9.

The Executive's termination for Cause shall be effective when and if a resolution is duly adopted at the Special Board Meeting, stating that, in the good faith opinion of the Board, the Executive is guilty of the conduct described in the Notice of -15- Termination for Cause, and such conduct constitutes Cause under this Agreement. (c) GOOD REASON. (i) The Executive may terminate employment for Good Reason or without Good Reason. "Good Reason" means: A. the assignment to the Executive of any duties inconsistent in any material respect with paragraph (a) or, if applicable, (b) of Section 2 of this Agreement, or any other action by the Company that results in a material diminution in the Executive's position, authority, duties or responsibilities, other than an action that is not taken in bad faith and is remedied by the Company promptly after receipt of notice thereof from the Executive; B. any material failure by the Company to comply with any provision of Section 3 of this Agreement, other than a failure that is not taken in bad faith and is remedied by the Company promptly after receipt of notice thereof from the Executive; C. any requirement by the Company that the Executive's services be rendered primarily at a location or locations other than that provided for in paragraph (d) of Section 2 of this Agreement, other than normal business travel; D. any purported termination of the Executive's employment by the Company for a reason or in a manner not expressly permitted by this Agreement; or E. any failure by the Company to comply with paragraph (c) of Section 10 of this Agreement.

A termination of employment by the Executive for Good Reason shall be effective on the fifth business day following the date when the Notice of Termination for Good Reason is given, unless the notice sets forth a later date (which date shall in no event be later than 30 days after the notice is given).

(d) DATE OF TERMINATION. The "Date of Termination" means the date of the Executive's death, the Disability Effective Date, the date on which the termination of the Executive's employment by the Company for Cause or by the Executive for Good Reason or without Good Reason, as the case may be, is effective. 6.

NON-EXCLUSIVITY OF RIGHTS.

Vested benefits and other amounts that the Executive is otherwise entitled to receive -19- under any plan, policy, practice or program of, or any contract or agreement with, the Company or any of its affiliated companies on or after the Date of Termination shall be payable in accordance with such plan, policy, practice, program, contract or agreement, as the case may be, except as explicitly modified by this Agreement. 8.
