                  SPLIT DOLLAR ASSIGNMENT TERMINATION AGREEMENT

         This SPLIT DOLLAR ASSIGNMENT TERMINATION AGREEMENT ("Termination
Agreement") by and between Health Care and Retirement Corporation of America
("Company"), Manor Care, Inc. ("Manor Care"), Heartland Employment Services,
Inc. ("HES") and _________________________ ("Employee") is effective December
16, 2003.

                                    RECITALS

         WHEREAS, Company and HES are direct or indirect subsidiaries of Manor
Care and serve as employer corporations for individuals providing services to or
on behalf of Manor Care and its subsidiaries and affiliated entities; and

         WHEREAS, from January 1, 2000 and continuing through the present,
Employee has been employed by HES; prior to January 1, 2000 Employee was
employed by Company; and

         WHEREAS, among other benefits provided to Employee by Company and HES
are executive life insurance benefits under the Supplemental Corporate
Officer-Senior Executive Life Insurance Program ("SCO-SELIP") pursuant to which
Employee is entitled to receive life insurance death benefits equal to two (2)
times salary, prior to retirement, and two (2) times final salary,
post-retirement (the "SCO - SELIP Benefits"); and

         WHEREAS, Company and HES elected to fund their obligations under the
SCO-SELIP through collateral assignment split dollar life insurance arrangements
("CASD") pursuant to which each participant under the SCO-SELIP became the owner
of life insurance policies subject to a collateral assignment to the Company of
a corporate interest equal to the amount of premiums paid by the Company or HES;
the CASD policies were designed to generate cash value such that at the
participant's retirement the policies would have generated sufficient cash value
to provide the SCO-SELIP Benefits without payment of additional premiums; and

         WHEREAS, Company and Employee entered into a Split Dollar Assignment
Insurance Agreement dated January 1, 1993 ("SDA") pursuant to which Employee
granted the Company the right to receive the corporate interest from the life
insurance policy(ies) supporting the SCO-SELIP obligations of Company (the
"Policy") and the Company agreed to pay the premiums on the Policy, with all
such premium payments being referred to as the "Corporate Interest"; and

         WHEREAS, Section 5.10 of the SDA provided that in the event of a change
in control, as defined in the SDA, the Company would be required to release a
portion of its

<PAGE>

Corporate Interest in the Policy and, if necessary, provide a gross-up payment
to the Employee for any income taxes payable on such transfer; and

         WHEREAS, the transaction in September, 1998 between the former Health
Care and Retirement Corporation and the former Manor Care, Inc. constituted a
change in control under Section 5.10 of the SDA; and

         WHEREAS, the provisions of the Sarbanes-Oxley Act, effective in July,
2002, negatively impacted the CASD arrangement by potentially prohibiting the
continued payment of premiums by Manor Care to the extent such payments may be
considered loans to the Employee; and

         WHEREAS, in order to comply with the potential prohibition of continued
premium payments by the Sarbanes-Oxley Act, the Company discontinued premium
payments under the SDA; and

         WHEREAS, in September, 2003 the Internal Revenue Service adopted
regulations the effect of which will be to change the tax treatment of the SDA
by causing the cash value in the Policy to become taxable to the Employee at
retirement; and

         WHEREAS, IRS Notice 2002-8 established a "safe harbor" so that if the
SDA is terminated prior to January 1, 2004 the cash value of the Policy will not
be taxable to Employee at the time of such termination; and

         WHEREAS, the provisions of Sarbanes-Oxley and the IRS regulations and
notices referenced above, have impacted the original design of the SCO-SELIP so
as to reduce the advantages and benefits of the CASD arrangements for both the
Company and the participants; and

         WHEREAS, the Compensation Committee of the Manor Care Board of
Directors has received and reviewed the recommendations of its consulting firm,
Watson Wyatt, regarding the implementation of Section 5.10 of the SDA, as well
as Watson Wyatt's recommendation regarding the provisions of Sarbanes-Oxley Act
and the IRS regulations and notices referenced above; and

         WHEREAS, in view of the recommendations of Watson Wyatt, the
Compensation Committee has approved the termination of the SDA pursuant to
Section 4.1(c) thereof on the terms and conditions stated herein; and

         WHEREAS, in light of the potential adverse tax consequences of
continuing the SDA, the Employee also desires to terminate the SDA pursuant to
Section 4.1(c) thereof on the terms and conditions stated herein.

         NOW THEREFORE, in consideration of the foregoing and the mutual
promises and commitments contained herein, and for other good and valuable
consideration, the parties agree as follows:

Employee retains an amount of the payment sufficient to pay premiums on the
Policy in the amount necessary to (i) provide a cash value of the Policy
necessary to sustain the Policy equal to the Termination Death Benefit, in the
event that the waiver of the Corporate Interest under Paragraph 2 of this
Termination Agreement was not sufficient to provide such benefits; (ii) increase
the death benefits available under the Policy to account for future salary
increases of Employee so that the Policy will be sufficient to provide an amount
equal to the SCO-SELIP Benefit; and (iii) maintain the death benefits available
under the Policy in the event of any shortfalls under the Policy.

         4. Gross-Up Payment on Waiver of Corporate Interest. HES agrees to make
an additional payment to Employee, within 30 days following the date hereof, in
