                                MANOR CARE, INC.
                             THIRD RIGHTS AMENDMENT
                             ----------------------

         THIRD AMENDMENT, dated as of March 11, 2000 (this "Amendment"), to the
Rights Agreement, dated as of May 2, 1995, as amended, (the "Rights Agreement"),
between MANOR CARE, INC., as successor to HEALTH CARE AND RETIREMENT
CORPORATION, a Delaware corporation (the "Company"), and HARRIS TRUST AND
SAVINGS BANK (the "Rights Agent").

         The Company and the Rights Agent have heretofore executed and entered
into the Rights Agreement. Pursuant to Section 26 of the Rights Agreement, the
Company and the Rights Agent may from time to time supplement or amend the
Rights Agreement in accordance with the provisions of Section 26 thereof. All
acts and things necessary to make this Amendment a valid agreement according to
its terms have been done and performed, and the execution and delivery of this
Agreement by the Company and the Rights Agent have been in all respects
authorized by the Company and the Rights Agent.

         In consideration of the foregoing premises and mutual agreements set
forth in the Rights Agreement and this Amendment, the parties hereto agree as
follows:

         1. The definition of "Acquiring Person" set forth in Section 1.1 of the
Rights Agreement is hereby modified by and amended by adding the following
sentence at the end thereof:

                  Notwithstanding the foregoing, none of (i) Stewart Bainum,
                  Jr., (ii) any other Person or group approved by the Board of
                  Directors or the Special Committee of the Board of Directors
                  of the Company (any of Stewart Bainum, Jr. and each such other
                  Person or group being an "Approved Person") and (iii) each
                  other stockholder of the Company with whom an Approved Person
                  may from time to time be deemed to have formed a group shall
                  become an Acquiring Person solely as a result of Permitted
                  Actions (as such term is hereinafter defined) taken on or
                  after March 10, 2000 and prior to the Company's announcement
                  of either an Extraordinary Transaction (as hereinafter
                  defined) with a Person other than the Approved Person or that
                  the Company is no longer exploring the possibility of an
                  Extraordinary Transaction (the "Termination Time"). "Permitted
                  Action" means having non-public discussions with stockholders
                  of the Company solely to inquire whether they would be
                  interested in becoming participants

                               Page 4 of 6 Pages

                  in the submission by an Approved Person of a proposal for a
                  negotiated acquisition of the Company pursuant to an
                  invitation from the Special Committee of the Company's Board
                  of Directors (and provided no information is disclosed to such
                  stockholders in violation of any agreement between the
                  Approved Person and the Company) or entering into any
                  arrangements, agreements or understandings with such
                  stockholders solely regarding such participation, provided
                  that all parties (including the Approved Person) party to such
                  agreements, arrangements or understandings do not in the
                  aggregate beneficially own more than 35% of the then
                  outstanding Common Shares of the Company and any such
                  arrangement, agreement or understanding must, by its terms,
                  automatically terminate at the Termination Time.
                  "Extraordinary Transaction" shall occur if the Board of
                  Directors of the Company approves a transaction (or a binding
                  agreement relating thereto) with any person or group that
                  would result in such person or group beneficially owning more
                  than 35% of the outstanding voting securities of the Company
                  (or a successor to the Company in a merger or consolidation
                  transaction) or all or substantially all of its assets, a
                  transaction with any person or group involving a merger,
                  consolidation, tender or exchange offer, recapitalization or
                  other business combination or similar transaction involving
                  the Company or its subsidiaries or that would result in any
                  person or group (other than the Company's Board of Directors)
                  having the right to elect or appoint a majority of the members
                  of the Company's Board of Directors, or any person or "group"
                  (as defined in the Exchange Act) has commenced or publicly
                  announced its intention to commence a tender or exchange offer
                  for more than 35% of the outstanding voting securities of the
                  Company.

         2. This Amendment to the Rights Agreement shall be effective as of
March 10, 2000.

         3. Except as expressly amended hereby, the Rights Agreement remains in
full force and effect in accordance with its terms.

         4. The Rights Agreement, as amended by this Agreement, and each Right
and each Rights Certificate exist under and pursuant to the Delaware General
Corporation Law.

         5. This Amendment to the Rights Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware.

         6. This Amendment to the Rights Agreement may be executed in any number
of counterparts and each of such counterparts shall for all purposes be deemed
an original, and all such counterparts shall together constitute but one and the
same instrument.

         7. Except as expressly set forth herein, this Amendment to the Rights
Agreement shall not by implication or otherwise alter, modify, amend or in any
way affect any of the terms, conditions, obligations, covenants or agreements
contained in the Rights Agreement, all of which are ratified and affirmed in all
respects and shall continue in full force and effect.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Amendment to the Rights Agreement to be duly executed as of the day and year
first above written.

         3. ADMINISTRATION.

            (a) Board Administration. The Plan will be administered by the
Board. The Board may delegate its administrative duties and authority (other
than its authority to amend the Plan) to any Board committee or to any officers
or employees or committee thereof as the Board may designate (in which case
references to the Board will be deemed to refer to the administrator to which
such duties and authority have been delegated). The Board will have full
authority to adopt, amend, suspend, waive, and rescind rules and regulations and
appoint agents as it deems necessary or advisable to administer the Plan, to
correct any defect or supply any omission or reconcile any inconsistency in the
Plan and to construe and interpret the Plan and rules and regulations
thereunder, to furnish to the Custodian such information as the Custodian may
require, and to make all other decisions and determinations under the Plan
(including determinations relating to eligibility). No person acting in
connection with the administration of the Plan will, in that capacity,
participate in deciding any matter relating to his or her participation in the
Plan.

            (b) The Custodian. The Custodian will act as custodian under the
Plan, and will perform duties under the Plan and in any agreement between the
Company and the Custodian. The Custodian will establish and maintain
Participants Stock Accounts and any subaccounts as may be necessary or desirable
to administer the Plan.

            (c) Waivers. The Board may waive or modify any requirement that a
notice or election be made or filed under the Plan a specified period in advance
on an individual case or by adopting a rule or regulation under the Plan,
without amending the Plan.

            (d) Other Administrative Provisions. The Company will furnish
information from its records as directed by the Board, and such records,
including a Participant's Earnings, will be conclusive on all persons unless
determined by the Board to be incorrect. Each Participant and other person
claiming benefits under the Plan must furnish to the Company in writing an
up-to-date mailing address and any other information as the Board or Custodian
may reasonably request. Any communication, statement, or notice mailed with
postage prepaid to

                                     - 2 -
<PAGE>   3
any such Participant or other person at the last mailing address filed with the
Company will be deemed sufficiently given when mailed and will be binding upon
the named recipient. The Plan will be administered on a reasonable and
nondiscriminatory basis and uniform rules will apply to all persons similarly
situated. All Participants will have equal rights and privileges (subject to the
terms of the Plan) with respect to Purchase Right outstanding during any given
Offering Period.

         4. STOCK SUBJECT TO PLAN. Subject to adjustment as provided below, the
total number of shares of Stock reserved and available for issuance or which may
be otherwise acquired upon exercise of Purchase Rights under the Plan will be
400,000. Any shares of Stock delivered by the Company under the Plan may
consist, in whole or in part, of authorized and unissued shares or treasury
shares. The number and kind of such shares of Stock subject to the Plan will be
proportionately adjusted, as determined by the Board, in the event of any
extraordinary dividend or other distribution, recapitalization, forward or
reverse split, reorganization, merger, consolidation, spin-off, combination,
repurchase, or share exchange, or other similar corporate transaction or event
affecting the Stock.

         5. ENROLLMENT AND CONTRIBUTIONS.

            (a) Eligibility. An employee of the Company or a Subsidiary may be
enrolled in the Plan for any Offering Period if such employee is employed by the
Company or a Subsidiary on the first day of the Offering Period, unless one of
the following applies to the employee:

                (i)    such person has been employed by the Company or a
                       Subsidiary less than 90 days, or

                (ii)   such person is customarily employed by the Company or a
                       Subsidiary for 20 hours or less a week; or

                (iii)  such person is customarily employed by the Company or a
                       Subsidiary for not more than five months in any calendar
                       year; or

                (iv)   such person would, immediately upon enrollment, be deemed
                       to own, for purposes of Section 423(b)(3) of the Code, an
                       aggregate of five percent or more of the total combined
                       voting power or value of all outstanding shares of all
                       classes of the Company or any Subsidiary.

The Company will notify an employee of the date as of which he or she is
eligible to enroll in the Plan, and will make available to each eligible
employee the necessary enrollment forms. Notwithstanding the above, any
individual who is employed by the Company or a Subsidiary and who is working
outside of the United States shall not be eligible to participate in the Plan if
the laws of the country in which the employee is working makes the offer of the
Purchase Right or the delivery of Stock under the Plan impractical.
Additionally, the offer of the Purchase Right and the delivery of Stock under
the Plan shall only be effective for any individual who is employed by the
Company or a Subsidiary and who is working outside of the United States only
after the Company has complied with the applicable laws of the country in which
the employee is working.

                                     - 3 -

            (b) Initial Enrollment. An employee who is eligible under Section
5(a) (or who will become eligible on or before a given Offering Period) may,
after receiving current information about the Plan, initially enroll in the Plan
by executing and filing with the Company a properly completed enrollment form,
including the employee's election as to the rate of payroll contributions for
the Offering Period. To be effective for any Offering Period, such enrollment
form must be filed at least two weeks preceding such Offering Period.

            (c) Automatic Re-enrollment for Subsequent Offering Periods. A
Participant whose enrollment in, and payroll contributions under, the Plan
continues throughout a Offering Period will automatically be re-enrolled in the
Plan for the next Offering Period unless (i) the Participant terminates
enrollment before the next Offering Period in accordance with Section 7(a), or
(ii) the Participant is ineligible to participate under Section 5(a). The
initial rate of payroll contributions for a Participant who is automatically
re-enrolled for a Offering Period will be the same as the rate of payroll
contribution in effect at the end of the preceding Offering Period, unless the
Participant files a new enrollment form designating a different rate of payroll
contributions and such new enrollment form is received no later than two weeks
prior to the beginning of the next Offering Period.

            (d) Payroll Contributions. A Participant will make contributions
under the Plan by means of payroll deductions from each payroll period which
ends during the Offering Period, at the rate elected by the Participant in his
or her enrollment form in effect for that Offering Period (except that such rate
may be changed during the Offering Period to the extent permitted below). The
rate of payroll contributions elected by a Participant may not be less than one
percent (1%) nor more than ten percent (10%) of the Participant's Earnings for
each payroll period, and only whole percentages may be elected; provided,
however, that the Board may specify a lower minimum rate and higher maximum
rate, subject to Section 8(c). Notwithstanding the above, a Participant's
payroll contributions will be adjusted downward by the Company as necessary to
ensure that the limit on the amount of Stock purchased with respect to a
Offering Period set forth in Section 6(a)(iii) is not exceeded. A Participant
may elect to increase, decrease, or discontinue payroll contributions for a
future Offering Period by filing a new enrollment form designating a different
rate of payroll contributions, which form must be received at least two weeks
prior to the beginning of an Offering Period to be effective for that Offering
Period. In addition, a Participant may elect to discontinue payroll
contributions during an Offering Period by filing a new enrollment form, such
change to be effective for the next payroll after the Participant's new
enrollment form is received.

            (e) Crediting Payroll Contributions to Cash Accounts. All payroll
contributions by a Participant under the Plan will be credited to a Cash Account
maintained by the Company on behalf of the Participant. The Company will credit
payroll contributions to each Participant's Cash Account as soon as practicable
after the contributions are withheld from the Participant's Earnings.

            (f) No Interest on Cash Accounts. No interest will be credited or
paid on cash balances in Participant's Cash Accounts pending investment in
Stock.

         6. PURCHASES OF STOCK

            (a) Purchase Rights. Enrollment in the Plan for any Offering Period
by a Participant will constitute a grant by the Company of a Purchase Right to
such Participant for such Offering Period. Each Purchase Right will be subject
to the following terms:

                (i)    The purchase price at which Stock will be purchased under
                       a Purchase Right will be as specified in Section 6(c).

                (ii)   Except as limited in (iii) below, the number of shares of
                       Stock that may be purchased upon exercise of the Purchase
                       Right for a Offering Period will equal the number of
                       shares (including fractional shares) that can be
                       purchased at the purchase price specified in Section 6(c)
                       with the aggregate amount credited to the Participant's
                       Cash Account as of the last day of an Offering Period.

                (iii)  The number of shares of Stock subject to a Participant's
                       Purchase Right for any Offering Period will not exceed
                       the number derived by dividing $12,500 by 100% of the
                       Fair Market Value of one share of Stock on the first day
                       of the Offering Period for the Offering Period.

                (iv)   The Purchase Right will be automatically exercised on the
                       last day of the Offering Period.

                (v)    Payments by a Participant for Stock purchased under a
                       Purchase Right will be made only through payroll
                       deduction in accordance with Section 5(d) and (e).

                (vi)   The Purchase Right will expire on the earlier of the last
                       day of the Offering Period or the date on which the
                       Participant's enrollment in the Plan terminates.

            (b) Purchase of Stock. At or as promptly as practicable after the
last day of an Offering Period, amounts credited to each Participant's Cash
Account will be applied by the Company to purchase Stock, in accordance with the
terms of the Plan. Shares of Stock will be purchased from the Company. The
Company will aggregate the amounts in all Cash Accounts when purchasing Stock,
and shares purchased will be allocated to each Participant's Stock Account in
proportion to the cash amounts withdrawn from such Participant's Cash Account.
After completing purchases for each Offering Period (which will be completed in
not more than 15 calendar days after the last day of an Offering Period), all
shares of Stock so purchased for a Participant will be credited to the
Participant's Stock Account.

            (c) Purchase Price. The purchase price of each share of Stock
purchased for each Offering Period will equal 85% of the lesser of (i) the Fair
Market Value of a share of Stock on the first day of an Offering Period, or (ii)
the Fair Market Value of a share of Stock on the last day of an Offering Period.

                                     - 5 -
<PAGE>   6
            (d) Dividend Reinvestment; Other Distributions. Cash dividends on
any Stock credited to a Participant's Stock Account will be automatically
reinvested in additional shares of Stock; such amounts will not be available in
the form of cash to Participants. The Company will aggregate all purchases of
Stock in connection with dividend reinvestment for a given dividend payment
date. Purchases of Stock for purposes of dividend reinvestment will be made as
promptly as practicable (but not more than 15 calendar days) after a dividend
payment date. The purchases will be made directly from the Company at 100% of
the Fair Market Value of a share of Stock on the dividend payment date. Any
shares of Stock distributed as a dividend or distribution in respect of shares
of Stock or in connection with a split of the Stock credited to a Participant's
Stock Account will be credited to such Account.

            (e) Withdrawals and Transfers. Shares of Stock may be withdrawn from
a Participant's Stock Account, in which case one or more certificates for whole
shares may be issued in the name of, and delivered to, the Participant, with
such Participant receiving cash in lieu of fractional shares based on the Fair
Market Value of a share of Stock on the day preceding the date of withdrawal.
Alternatively, whole shares of Stock may be withdrawn from a Participant's Stock
Account by means of a transfer to a broker-dealer or financial institution that
maintains an account for the Participant, together with the transfer of cash in
lieu of fractional shares based on the Fair Market Value of a share of Stock on
the day preceding the date of withdrawal. Participants may not designate any
other person to receive shares of Stock withdrawn or transferred under the Plan.
A Participant seeking to withdraw or transfer shares of Stock must give
instructions to the Custodian in such manner and form as may be prescribed by
the Custodian, which instructions will be acted upon as promptly as practicable.
Withdrawals and transfers will be subject to any fees imposed in accordance with
Section 8(a).

            (f) Excess Account Balances. If any amounts remain in a Cash Account
following the date on which the Company purchases Stock for an Offering Period
as a result of the limitation set forth in Section 6(a)(iii) or for any other
reason, such amounts will be returned to the Participant as promptly as
practicable.

         7. TERMINATION AND DISTRIBUTIONS.

            (a) Termination of Enrollment. A Participant's enrollment in the
Plan will terminate upon (i) the beginning of any payroll period or Offering
Period that begins after he or she files a written notice of termination of
enrollment with the Company, provided that such Participant will continue to be
deemed to be enrolled with respect to any completed Offering Period for which
purchases have not been completed, (ii) such time as the Participant becomes
ineligible to participate under Section 5(a) of the Plan, or (iii) the
termination of the Participant's employment by the Company and its Subsidiaries.
An employee whose enrollment in the Plan terminates may again enroll in the Plan
as of any subsequent Offering Period that is at least 90 days after such
termination of enrollment if he or she satisfies the eligibility requirements of
Section 5(a) as of such Offering Period. A Participant's election to discontinue
payroll contributions will not constitute a termination of enrollment.

            (b) Distribution. As soon as practicable after a Participant's
enrollment in the Plan terminates, amounts in the Participant's Cash Account
which resulted from payroll contributions will be repaid to the Participant. The
Custodian will continue to maintain the Participant's Stock Account for the
Participant until the earlier of such time as the Participant

                                     - 6 -

directs the sale of all Stock in the Account, withdraws, or transfers all Stock
in the Account, or one year after the Participant ceases to be employed by the
Company and its Subsidiaries. If a Participant's termination of enrollment
results from his or her death, all amounts payable will be paid to his or her
estate.

         8. GENERAL.

            (a) Costs. Costs and expenses incurred in the administration of the
Plan and maintenance of Accounts will be paid by the Company, to the extent
provided in this Section 8(a). Any brokerage fees and commissions for the
purchase of Stock under the Plan (including Stock purchased upon reinvestment of
dividends and distributions) will be paid by the Company, but any brokerage fees
and commissions for the sale of Stock under the Plan by a Participant will be
borne by such Participant. The rate at which such fees and commissions will be
charged to Participants will be determined by the Custodian or any broker-dealer
used by the Custodian (including an affiliate of the Custodian), and
communicated from time to time to Participants. In addition, the Custodian may
impose or pass through a reasonable fee for the withdrawal of Stock in the form
of stock certificates (as permitted under Section 6(e)), and reasonable fees for
other services unrelated to the purchase of Stock under the Plan, to the extent
approved in writing by the Company and communicated to Participants.

            (b) Statements to Participants. The Participant's statement will
reflect payroll contributions, purchases, sales, and withdrawals and transfers
of shares of Stock and other Plan transactions by appropriate adjustments to the
Participant's Accounts. The Custodian will, not less frequently than
semi-annually, provide or cause to be provided a written statement to the
Participant showing the transactions in his or her Stock Account and the date
thereof, the number of shares of Stock credited or sold, the aggregate purchase
price paid or sales price received, the purchase or sales price per share, the
brokerage fees and commissions paid (if any), the total shares held for the
Participant's Stock Account (computed to at least three decimal places), and
such other information as agreed to by the Custodian and the Company.

            (c) Compliance with Section 423. It is the intent of the Company
that this Plan comply in all respects with applicable requirements of Section
423 of the Code and regulations thereunder. Accordingly, if any provision of
this Plan does not comply with such requirements, such provision will be
construed or deemed amended to the extent necessary to conform to such
requirements.

         9. GENERAL PROVISIONS.

            (a) Compliance With Legal and Other Requirements. The Plan, the
granting and exercising of Purchase Rights hereunder, and the other obligations
of the Company and the Custodian under the Plan will be subject to all
applicable federal and state laws, rules, and regulations, and to such approvals
by any regulatory or governmental agency as may be required. The Company may, in
its discretion, postpone the issuance or delivery of Stock upon exercise of
Purchase Rights until completion of such registration or qualification of such
Stock or other required action under any federal or state law, rule, or
regulation, or the laws of any country in which employees of the Company and a
Subsidiary who are nonresident aliens and who are eligible to participate
reside, or other required action with respect to any automated quotation system
or stock exchange upon which the Stock or other Company securities are
designated or

                                     - 7 -
<PAGE>   8
listed, or compliance with any other contractual obligation of the Company, as
the Company may consider appropriate, and may require any Participant to make
such representations and furnish such information as it may consider appropriate
in connection with the issuance or delivery of Stock in compliance with
applicable laws, rules, and regulations, designation or listing requirements, or
other contractual obligations.

            (b) Limits on Encumbering Rights. No right or interest of a
Participant under the Plan, including any Purchase Right, may be pledged,
encumbered, or hypothecated to or in favor of any party, subject to any lien,
obligation, or liability of such Participant, or otherwise assigned,
transferred, or disposed of except pursuant to the laws of descent or
distribution, and any right of a Participant under the Plan will be exercisable
during the Participant's lifetime only by the Participant.

            (c) No Right to Continued Employment. Neither the Plan nor any
action taken hereunder, including the grant of a Purchase Right, will be
construed as giving any employee the right to be retained in the employ of the
Company or any of its Subsidiaries, nor will it interfere in any way with the
right of the Company or any of its Subsidiaries to terminate any employee's
employment at any time.

            (d) Taxes. The Company or any Subsidiary is authorized to withhold
from any payment to be made to a Participant, including any payroll and other
payments not related to the Plan, amounts of withholding and other taxes due in
connection with any transaction under the Plan, and a Participant's enrollment
in the Plan will be deemed to constitute his or her consent to such withholding.
In addition, Participants may be required to advise the Company of sales and
other dispositions of Stock acquired under the plan in order to permit the
Company to comply with tax laws and to claim any tax deductions to which the
Company may be entitled with respect to the Plan. This provision and other Plan
provisions do not set forth an explanation of the tax consequences to
Participants under the Plan. A brief summary of the tax consequences will be
included in disclosure documents to be separately furnished to Participants.

            (e) Changes to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan without the consent of shareholders or
Participants, except that any such action will be subject to the approval of the
Company's shareholders within one year after such Board action if such
shareholder approval is required by any federal or state law or regulation or
the rules of any automated quotation system or stock exchange on which the Stock
may then be quoted or listed, or if such shareholder approval is necessary in
order for the Plan to continue to meet the requirements of Section 423 of the
Code, and the Board may otherwise, in its discretion, determine to submit other
such actions to shareholders for approval. However, without the consent of an
affected Participant, no amendment, alteration, suspension, discontinuation, or
termination of the Plan may materially and adversely affect the rights of such
Participant with respect to outstanding Purchase Rights relating to any Offering
Period that has been completed prior to such Board action. The foregoing
notwithstanding, upon termination of the Plan the Board may elect to terminate
all outstanding Purchase Rights at such time as the Board may designate; in the
event of such termination of any Purchase Right prior to its exercise, all
amounts contributed to the Plan which remain in a Participant's Cash Account
will be returned to the Participant (without interest) as promptly as
practicable.

                                     - 8 -

            (f) No Rights to Participate; No Shareholder Rights. No Participant
or employee will have any claim to participate in the Plan with respect to
Offering Periods that have not commenced, and the Company will have no
obligation to continue the Plan. No Purchase Right will confer on any
Participant any of the rights of a shareholder of the Company unless and until
Stock is duly issued or transferred and delivered to the Participant (or
credited to the Participant's Stock Account).

            (g) Fractional Shares. Unless otherwise determined by the Board,
purchases of Stock under the Plan executed by the Custodian may result in the
crediting of fractional shares of Stock to the Participant's Stock Account. Such
fractional shares will be computed to at least three decimal places. Fractional
shares will not, however, be issued by the Company, and certificates
representing fractional shares will not be delivered to Participants under any
circumstances.

            (h) Plan Year. The Plan will operate on a plan year that begins on
January 1 and ends December 31 in each year.

            (i) Governing Law. The validity, construction, and effect of the
Plan and any rules and regulations relating to the Plan will be determined in
accordance with the laws of the State of Arizona, without giving effect to
principles of conflicts of laws, and applicable federal law.

            (j) Effective Date. The Plan will become effective on the First
Commencement Date, subject to the Plan being approved by shareholders of the
Company, at a meeting thereof, by a vote sufficient to meet the requirements of
Section 423(b)(2) of the Code. If the Plan is not approved in accordance with
Section 423(b)(2) of the Code, each Participant's Purchase Right shall be void
and amounts credited to the Participant's Cash Account shall be promptly
returned to the Participant. In the event the First Commencement Date does not
commence by December 31, 2000, the Plan shall be terminated notwithstanding any
approval thereof by shareholders of the Company.
