Retention Provisions and Stay Bonus. Up to the Effective Time of the Merger, the Employee shall continue to serve as Chairman of the Board, President and Chief Executive Officer of the Company. From the Effective Time of the Merger until December 31, 1998, the Employee shall be employed by the Company as a Special Consultant to HCR with such duties as reasonably requested by the President and reasonably agreed to by -3- the Employee. During this period, the Employee shall receive compensation and benefits at the rate and under the provisions in effect on the date hereof. If the Employee remains in employment with the Company until December 31, 1998, the Employee shall be entitled to receive within 30 days thereafter in a lump sum a special bonus in the amount of $838,724. Except as provided in Section 2 below, such special bonus shall not be payable if the Employee's employment with the Company terminates prior to December 31, 1998. 2. Bonus Upon Early Termination. (a) If the Employee's employment with the Company shall terminate prior to December 31, 1998 either (i) because of termination by the Company other than for Cause (as hereinafter defined) or (ii) because of termination by the Employee for Good Reason (as hereinafter defined), the Employee shall be entitled to receive a special bonus in the amount of $838,724. Such special bonus shall be paid in a lump sum within 30 days after the date of such termination of employment. (b) For purposes of this Agreement, "Cause" shall mean the Employee's (i) willfully engaging in conduct which is materially and demonstrably injurious to the Company, or (ii) willfully engaging in an act or acts of dishonesty resulting in -4- material personal gain to the Employee at the expense of the Company. (c) For purposes of this Agreement, "Good Reason" shall mean (i) a significant reduction after the Effective Time of the Merger in the scope of the Employee's authority, position, title, functions, duties or responsibilities as Special Consultant to HCR, (ii) the relocation of the Employee's office location to a location more than 25 miles away from the Employee's principal place of employment on the Effective Date, (iii) any reduction in the Employee's base salary, (iv) a significant change in the Company's annual bonus program adversely affecting the Employee, or (v) a significant reduction in the other employee benefits provided to the Employee. 3. Additional Benefits upon Termination Without Cause or For Good Reason. If the Employee's employment with the Company shall terminate (regardless of whether before December 31, 1998 or on or after such date) either (i) because of termination by the Company other than for Cause (as defined in Section 2(b)) or (ii) because of termination by the Employee for Good Reason (as defined in Section 2(c)), the Employee shall be entitled to the following: (a) The Company shall pay to the Employee as a bonus for the year of termination of his employment an -5- amount equal to a portion (determined as provided in the next sentence) of the maximum bonus that the Employee could have received under the Company's annual bonus program for the fiscal year in which his employment terminates. Such portion shall be determined by dividing the number of days of the Employee's employment during such fiscal year up to his termination of employment by 365 (366 if a leap year). Such payment shall be made in a lump sum within 30 days after the date of such termination of employment, and the Employee shall have no right to any further bonuses under said program. (b) The Employee shall receive under the Company's Supplemental Executive Retirement Plan (the "SERP") the benefits that he would have been entitled to receive under the SERP if he had continued in employment with the Company for the period beginning on his date of termination of employment and continuing thereafter for a period of years and months corresponding to the Applicable Multiple and had received base salary for such period at the rate in effect on such date of termination of employment. For purposes of this Agreement, the Applicable Multiple shall be the greater of (i) two years or (ii) the number of years from the date of the Employee's termination of employment until June 9, 2001 (such number of years to be determined by treating each -6- full 12-month period as one year and each month or part thereof in excess of full 12-month periods as one-twelfth of a year). (c) The Company shall credit to the Employee's Company Contribution Account under the Company's Nonqualified Retirement Savings and Investment Plan (the "Nonqualified Plan"), effective as of the date of the Employee's termination of employment, an amount equal to the product of (i) 6%, (ii) the Applicable Multiple, and (iii) the Employee's annual rate of base salary immediately preceding his termination of employment. In addition, effective as of the date of the Employee's termination of employment, the Employee's account balance under the Nonqualified Plan (as adjusted pursuant to the preceding sentence) shall be increased by a factor of 20%, and the Employee shall receive credit for vesting purposes for an additional period of service equal to the period of years and months corresponding to the Applicable Multiple. 4. Entitlement To Other Benefits. Except as provided in this Agreement, this Agreement shall not be construed as limiting in any way any rights or benefits that the Employee or his spouse, dependents or beneficiaries may have pursuant to any other plan or program of the Company. -7- 5. Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall, if the Employee so elects, be settled by arbitration, conducted before a panel of three arbitrators in Washington, D.C. in accordance with the applicable rules and procedures of the American Arbitration Association then in effect.

Successors. This Agreement shall be binding upon and inure to the benefit of the Employee and his estate and the Company and any successor or Parent (as hereinafter de- -8- fined) of the Company, but neither this Agreement nor any rights arising hereunder may be assigned or pledged by the Employee.

Severability.
