         WHEREAS, Executive served as HCA's Chief Executive Officer and Chairman
from July 1997 to January 2001, and as Chairman until January 2002, without

reputation, business and prospects of HCA;

         WHEREAS, the Executive desires to retire as an employee of the Company
and as Chairman of HCA as of January 1, 2002; and

         WHEREAS, the Company, HCA and Executive desire to enter into this
agreement on the terms and conditions set forth herein or under the terms of all
employee benefit plans and programs in which Executive was a participant in
accordance with the terms of such plans and programs;

         NOW, THEREFORE, the parties agree as follows:

         1.     Executive shall receive a one-time payment of $30,352.39, less
                withholding taxes, to enable Executive to continue medical
                insurance comparable to that currently provided by the Company.

         2.     The Company shall provide or reimburse the Executive for office
                space and reasonable office equipment, including supplies,
                furniture and fixtures, comparable to the Executive's existing
                office and equipment. This arrangement shall terminate upon
                written notice by the Executive.

         3.     The Company shall employ an Administrative Assistant of
                Executive's choosing for the Executive's clerical support. The
                Assistant shall remain an employee of the Company subject to the
                policies of the Company until the Assistant's voluntary
                termination, release by the Company at the Executive's request
                or until such time as the Executive chooses to no longer

                the budget guidelines used for other employees of the Company.

                any resulting compensation change.
