documents, agreements, certificates, indentures, notices and other writings,
however evidenced.

                           (ii) The term "including" is not limiting and means
                  "including without limitation."

                           (iii)In the computation of periods of time from a
         specified date to a later specified date, the word "from" means "from
         and including"; the words "to" and "until" each mean "to but
         excluding", and the word "through" means "to and including."

because of the Agent's or Banks' involvement in their preparation.

         1.3.     ACCOUNTING PRINCIPLES.

                  (a) Unless the context otherwise clearly requires, all
accounting terms not expressly defined herein shall be construed, and all
financial computations required under this Agreement shall be made, in
accordance with GAAP. In the event a change in GAAP causes a change in the
results of calculation of the financial covenants, standards or terms found in
this Agreement, the Borrowers, the Agent and the Banks agree to negotiate in
good faith adjustments to the provisions of this Agreement to reflect such
change with the desired result that the criteria for evaluating the Borrowers'
financial condition shall be the same after such change as if such change had
not been made, it being understood that any such adjustments are subject to the
consent of the Majority Banks.

                  (b) References herein to "fiscal year" and "fiscal quarter"
refer to such fiscal periods of the Company.


                                   ARTICLE II

                                   THE CREDITS

         2.1. AMOUNTS AND TERMS OF COMMITMENTS. Each Bank severally agrees, on
the terms and conditions set forth herein, to make loans to the Borrowers (each
such loan, a "REVOLVING LOAN") from time to time on any Business Day during the
period from the Effective Date to the Revolving Termination Date, in an
aggregate amount not to exceed at any time outstanding the amount set forth on
SCHEDULE 2.1 (such amount as the same may be reduced under SECTION 2.5 or as a
result of one or more assignments under SECTION 9.8, the Bank's "COMMITMENT");
PROVIDED, HOWEVER, that, after giving effect to any Committed Borrowing of
Revolving Loans, the aggregate principal amount of all outstanding Revolving
Loans outstanding at such time, shall not at any time exceed the combined
Commitments; and PROVIDED FURTHER, that, after giving effect to such Committed
Borrowing of Revolving Loans, the aggregate principal amount of all outstanding
Revolving Loans of any Bank at such time shall not at any time exceed such
Bank's Commitment. Within the limits of each Bank's Commitment, and subject to
the other terms and conditions hereof, the Borrowers may borrow under this
SECTION 2.1, prepay under SECTION 2.6 and reborrow under this SECTION 2.1.

         2.2.     LOAN ACCOUNTS.

                  (a) The Loans made by each Bank shall be evidenced by one or
more accounts or records maintained by such Bank in the ordinary course of
business. The accounts or records maintained



                                       26

<PAGE>   32



by the Agent and each Bank shall, in the absence of manifest or demonstrable
error, be presumptive evidence of the amount of the Loans made by the Banks to
the Borrowers, and the interest and payments thereon. Any failure so to record
or any error in doing so shall not, however, limit or otherwise affect the
obligation of the Borrowers hereunder to pay any amount owing with respect to
the Loans.

                  (b) Upon the request of any Bank made through the Agent, the
Loans made by such Bank may be evidenced by one or more Notes, instead of or in
addition to loan accounts. Each such Bank shall endorse on the schedules annexed
to its Note(s) the date, amount and maturity of each Loan made by it and the
amount of each payment of principal made by the Borrowers with respect thereto.
Each such Bank is irrevocably authorized by the Borrowers to endorse its Note(s)
and each Bank's record shall be conclusive absent manifest or demonstrable
error; provided, however, that the failure of a Bank to make, or an error in
making, a notation thereon with respect to any Loan shall not limit or otherwise
affect the obligations of the Borrowers hereunder or under any such Note to such
Bank.

         2.3.     PROCEDURE FOR COMMITTED BORROWING.

                  (a) Each Committed Borrowing shall be made upon a Borrower's
irrevocable telephonic notice delivered to the Agent (which notice must be
received by the Agent prior to (i) 8:00 a.m. (San Francisco time) two Business
Days prior to the requested Borrowing Date, in the case of Offshore Rate Loans,
and (ii) 10:00 a.m. (San Francisco time) on the requested Borrowing Date, in the
case of Base Rate Committed Loans, and which notice shall be promptly confirmed
by a written Notice of Borrowing transmitted by facsimile, in each case
specifying:

                  (i) the amount of the Committed Borrowing, which shall be in
         an aggregate minimum amount of $3,000,000 or any multiple of $1,000,000
         in excess thereof;

                  (ii) the requested Borrowing Date, which shall be a Business
         Day;

                  (iii) the Type of Loans comprising the Committed Borrowing;
         and

                  (iv) the duration of the Interest Period applicable to such
         Committed Loans included in such notice. If the Notice of Borrowing
         fails to specify the duration of the Interest Period for any Committed
         Borrowing comprised of Offshore Rate Loans, such Interest Period shall
         be one month.



                                       27

<PAGE>   33



                  (b) The Agent will promptly notify each Bank of its receipt of
any Notice of Borrowing and of the amount of such Bank's Pro Rata Share of that
Committed Borrowing.

                  (c) Each Bank will make the amount of its Pro Rata Share of
each Committed Borrowing available to the Agent for the account of the
applicable Borrower at the Agent's Payment Office by 11:00 a.m. (San Francisco
time) on the Borrowing Date requested by such Borrower in funds immediately
available to the Agent. The proceeds of all such Committed Loans will then be
made available to the applicable Borrower by the Agent by wire transfer in
accordance with written instructions provided to the Agent by such Borrower of
like funds as received by the Agent.

                  (d) After giving effect to any Committed Borrowing, unless the
Agent shall otherwise consent, there may not be more than 15 different Interest
Periods in effect in respect of all Committed Loans then outstanding.

         2.4.     CONVERSION AND CONTINUATION ELECTIONS FOR COMMITTED
BORROWINGS.

                  (a) A Borrower may, upon irrevocable telephonic notice in the
form of EXHIBIT B to the Agent in accordance with SECTION 2.4(b):

                  (i) elect, as of any Business Day, in the case of Base Rate
         Committed Loans, or as of the last day of the applicable Interest
         Period, in the case of any other Type of Committed Loans, to convert
         any such Committed Loans (or any part thereof in an amount not less
         than $3,000,000, or that is in an integral multiple of $1,000,000 in
         excess thereof) into Committed Loans of any other Type; or

                  (ii) elect, as of the last day of the applicable Interest
         Period, to continue any Committed Loans having Interest Periods
         expiring on such day (or any part thereof in an amount not less than
         $3,000,000, or that is in an integral multiple of $1,000,000 in excess
         thereof);

PROVIDED, that if at any time the aggregate amount of Offshore Rate Committed
Loans in respect of any Committed Borrowing is reduced, by payment, prepayment,
or conversion of part thereof to be less than $3,000,000, such Offshore Rate
Committed Loans shall automatically convert into Base Rate Committed Loans, and
on and after such date the right of such Borrower to continue such Committed
Loans as, and convert such Committed Loans into, Offshore Rate Committed Loans
shall terminate.



                                       28

<PAGE>   34



                  (b) A Borrower shall deliver telephonic notice to be received
by the Agent not later than (i) 8:00 a.m.(San Francisco time) at least two
Business Days in advance of the Conversion/ Continuation Date, if the Committed
Loans are to be converted into or continued as Offshore Rate Committed Loans,
and (ii) 10:00 a.m. (San Francisco time) on the Conversion/Continuation Date, if
the Loans are to be converted into Base Rate Committed Loans, and which notice
shall be promptly confirmed by a written Notice of Conversion/Continuation
transmitted by facsimile, in each case specifying:

                  (i) the proposed Conversion/Continuation Date;

                  (ii) the aggregate amount of Committed Loans to be converted
         or continued;

                  (iii) the Type of Committed Loans resulting from the proposed
         conversion or continuation; and

                  (iv) other than in the case of conversions into Base Rate
         Committed Loans, the duration of the requested Interest Period.

                  (c) If upon the expiration of any Interest Period applicable
to Offshore Rate Committed Loans, a Borrower has failed to select timely a new
Interest Period to be applicable to such Offshore Rate Committed Loans, or if
any Event of Default then exists, such Borrower shall be deemed to have elected
to convert such Offshore Rate Committed Loans into Base Rate Committed Loans
effective as of the expiration date of such Interest Period.

                  (d) The Agent will promptly notify each Bank of its receipt of
a Notice of Conversion/ Continuation, or, if no timely notice is provided by a
Borrower, the Agent will promptly notify each Bank of the details of any
automatic conversion. All conversions and continuations shall be made ratably
according to the respective outstanding principal amounts of the Committed Loans
with respect to which the notice was given held by each Bank.

                  (e) Unless the Majority Banks otherwise consent, during the
existence of an Event of Default, the Borrowers may not elect to have a
Committed Loan converted into or continued as an Offshore Rate Committed Loan.

                  (f) After giving effect to any conversion or continuation of
Committed Loans, unless the Agent shall otherwise consent, there may not be more
than 15 different Interest Periods in effect in respect of all Committed Loans.



                                       29

<PAGE>   35



         2.5.     VOLUNTARY TERMINATION OR REDUCTION OF COMMITMENTS. The
Borrowers may, upon not less than three Business Days' prior notice to the
Agent, terminate the Commitments, or permanently reduce the Commitments by an
aggregate minimum amount of $5,000,000 or any multiple of $1,000,000 in excess
thereof; unless, after giving effect thereto and to any prepayments of Committed
Loans made on the effective date thereof, the then-outstanding principal amount
of the Loans would exceed the amount of the combined Commitments then in effect.
Once reduced in accordance with this Section, the Commitments may not be
increased. Any reduction of the Commitments shall be applied to each Bank
according to its Pro Rata Share.

         2.6.    OPTIONAL AND MANDATORY PREPAYMENTS; MANDATORY COMMITMENT
REDUCTIONS. Subject to SECTION 3.4, the Borrowers may, at any time or from time
to time, upon not less than one Business Day's irrevocable notice to the Agent,
ratably prepay Committed Loans in whole or in part, in minimum amounts of
$3,000,000 or any multiple of $1,000,000 in excess thereof. Such notice of
prepayment shall specify the date and amount of such prepayment and the Type(s)
of Committed Loans to be prepaid. The Agent will promptly notify each Bank of
its receipt of any such notice, and of such Bank's Pro Rata Share of such
prepayment. If such notice is given by the Borrowers, the Borrowers shall make
such prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein, together with (except in the case of Base
Rate Committed Loans) accrued interest to each such date on the amount prepaid
and any amounts required pursuant to SECTION 3.4.

         2.7.     REPAYMENT. The Borrowers shall repay to the Banks on the
Revolving Termination Date the aggregate principal amount of Revolving Loans
outstanding on such date.

         2.8.     INTEREST.

                  (a) Each Committed Loan shall bear interest on the outstanding
principal amount thereof from the applicable Borrowing Date at a rate per annum
equal to the Offshore Rate or the Base Rate, as the case may be (and subject to
the Borrowers' right to convert to other Types of Loans under SECTION 2.4), plus
the Applicable Margin.

                  (b) Interest on each Loan shall be paid in arrears on each
Interest Payment Date. During the existence of any Event of Default, interest
shall be paid on demand of the Agent at the request or with the consent of the
Majority Banks.

                  (c) Notwithstanding subsection (a) of this Section, while any
Event of Default exists or after acceleration, the



                                       30

<PAGE>   36



Borrowers shall pay interest (after as well as before entry of judgment thereon
to the extent permitted by law) on the principal amount of all outstanding
Obligations, at a rate per annum which is determined by adding 2% per annum to
the Applicable Margin then in effect for such Loans and, in the case of
Obligations not subject to an Applicable Margin, at a rate per annum equal to
the Base Rate plus 2%; PROVIDED, HOWEVER, that, on and after the expiration of
any Interest Period applicable to any Offshore Rate Loan outstanding on the date
of occurrence of such Event of Default or acceleration, the principal amount of
such Loan shall, during the continuation of such Event of Default or after
acceleration, bear interest at a rate per annum equal to the Base Rate plus 2%.

         2.9.     FEES.

                  (a) ARRANGEMENT, AGENCY FEES. The Company shall pay an
arrangement fee to the Lead Arranger for the Lead Arranger's own account, and
shall pay an agency fee to the Agent for the Agent's own account, as required by
the letter agreement ("Fee Letter") between the Company and the Lead Arranger
and Agent dated August 26, 1998.

                  (b) FACILITY FEES. The Borrowers shall pay to the Agent for
the account of each Bank a facility fee on such Bank's Commitment (whether used
or unused), computed on a quarterly basis in arrears on the last Business Day of
each calendar quarter, at a rate per annum equal to the Applicable Facility Fee
Rate. Such facility fee shall accrue from the Effective Date to the Revolving
Termination Date and shall be due and payable quarterly in arrears on the last
Business Day of each calendar quarter, commencing on December 31, 1998 through
the Revolving Termination Date, with the final payment to be made on the
Revolving Termination Date. The facility fees provided in this subsection shall
accrue at all times after the above-mentioned commencement date, including at
any time during which one or more conditions in Article IV are not met.

                  (c) UTILIZATION FEES. If on any date the sum of (i) the
aggregate utilization of this Agreement and (ii) the aggregate utilization of
the $500,000,000 Credit Agreement shall exceed 50% (fifty percent) of the sum of
(i) the aggregate Commitments under this Agreement and (ii) the aggregate
commitments of the Banks under the $500,000,000 Credit Agreement, the Borrowers
shall pay to the Agent for the account of each Bank an amount equal to .05 of 1%
(one percent)of the aggregate amount of the utilization of the Agreement as of
each such date, computed on a quarterly basis in arrears on the last Business
Day of each calendar quarter, commencing on December 31, 1998 through the
Revolving Termination Date, with the final payment, if any, to be made on the
Revolving Termination Date.



                                       31

<PAGE>   37



         2.10.    COMPUTATION OF FEES AND INTEREST.

                  (a) All computations of interest for Base Rate Committed Loans
when the Base Rate is determined by BofA's "reference rate" shall be made on the
basis of a year of 365 or 366 days, as the case may be, and actual days elapsed.
All other computations of fees and interest shall be made on the basis of a
360-day year and actual days elapsed (which results in more interest being paid
than if computed on the basis of a 365-day year). Interest and fees shall accrue
during each period during which interest or such fees are computed from the
first day thereof to the last day thereof.

                  (b) Each determination of an interest rate by the Agent shall
be conclusive and binding on the Borrowers and the Banks in the absence of
manifest or demonstrable error. The Agent will, at the request of the Borrowers
or any Bank, deliver to the Borrowers or the Bank, as the case may be, a
statement showing the quotations used by the Agent in determining any interest
rate.

         2.11.    PAYMENTS BY THE BORROWERS.

                  (a) All payments to be made by the Borrowers shall be made
without set-off, recoupment or counterclaim. Except as otherwise expressly
provided herein, all payments by the Borrowers shall be made to the Agent for
the account of the Banks at the Agent's Payment Office, and shall be made in
dollars and in immediately available funds, no later than 10:00 a.m. (San
Francisco time) on the date specified herein. The Agent will promptly distribute
to each Bank its Pro Rata Share (or other applicable share as expressly provided
herein) of such payment in like funds as received. Any payment received by the
Agent later than 10:00 a.m. (San Francisco time) shall be deemed to have been
received on the following Business Day and any applicable interest or fee shall
continue to accrue.

                  (b) Subject to the provisions set forth in the definition of
"Interest Period" herein, whenever any payment is due on a day other than a
Business Day, such payment shall be made on the following Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be.

                  (c) Unless the Agent receives notice from the Borrowers prior
to the date on which any payment is due to the Banks that a Borrower will not
make such payment in full as and when required, the Agent may assume that the
Borrowers have made such payment in full to the Agent on such date in
immediately available funds and the Agent may (but shall not be so required),



                                       32

<PAGE>   38



in reliance upon such assumption, distribute to each Bank on such due date an
amount equal to the amount then due such Bank. If and to the extent the
Borrowers have not made such payment in full to the Agent, each Bank shall repay
to the Agent on demand such amount distributed to such Bank, together with
interest thereon at the Federal Funds Rate for each day from the date such
amount is distributed to such Bank until the date repaid.

         2.12.    PAYMENTS BY THE BANKS TO THE AGENT.

                  (a) Unless the Agent receives notice from a Bank on or prior
to the Effective Date or, with respect to any Borrowing after the Effective
Date, at least one Business Day prior to the date of such Committed Borrowing,
that such Bank will not make available as and when required hereunder to the
Agent for the account of the Borrowers the amount of that Bank's Pro Rata Share
of the Committed Borrowing, the Agent may assume that each Bank has made such
amount available to the Agent in immediately available funds on the Borrowing
Date and the Agent may (but shall not be so required), in reliance upon such
assumption, make available to the Borrowers on such date a corresponding amount.
If and to the extent any Bank shall not have made its full amount available to
the Agent in immediately available funds and the Agent in such circumstances has
made available to the Borrowers such amount, that Bank shall on the Business Day
following such Borrowing Date make such amount available to the Agent, together
with interest at the Federal Funds Rate for each day during such period. A
notice of the Agent submitted to any Bank with respect to amounts owing under
this subsection (a) shall be conclusive, absent manifest error. If such amount
is so made available, such payment to the Agent shall constitute such Bank's
Loan on the date of Borrowing for all purposes of this Agreement. If such amount
is not made available to the Agent on the Business Day following the Borrowing
Date, the Agent will notify the Borrowers of such failure to fund and, upon
demand by the Agent, the Borrowers shall pay such amount to the Agent for the
Agent's account, together with interest thereon for each day elapsed since the
date of such Committed Borrowing, at a rate per annum equal to the interest rate
applicable at the time to the Committed Loans comprising such Committed
Borrowing.

                  (b) The failure of any Bank to make any Committed Loan on any
Borrowing Date shall not relieve any other Bank of any obligation hereunder to
make a Committed Loan on such Borrowing Date, but no Bank shall be responsible
for the failure of any other Bank to make the Committed Loan to be made by such
other Bank on any Borrowing Date.

         2.13.    SHARING OF PAYMENTS, ETC. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Committed Loans made
by it any payment (whether



                                       33

<PAGE>   39



voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) in excess of its Pro Rata Share, such Bank shall immediately (a)
notify the Agent of such fact, and (b) purchase from the other Banks such
participations in the Committed Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Bank, such purchase shall to that
extent be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price paid therefor, together with an amount equal to such paying
Bank's ratable share (according to the proportion of (i) the amount of such
paying Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. The Borrowers agree
that any Bank so purchasing a participation from another Bank may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Bank were the direct creditor of the Borrowers in the amount of such
participation. The Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Banks following any such purchases or
repayments.

         2.14. EXTENSION OF REVOLVING TERMINATION DATE. Not more than 60 nor
less than 30 days prior to the then-scheduled Revolving Termination Date, the
Company may, at its option, request that the scheduled Revolving Termination
Date be extended for an additional 364 days by means of a letter, addressed to
the Agent and each Bank, substantially in the form of EXHIBIT F. Each Bank
consenting (in its sole and complete discretion) so to extend the scheduled
Revolving Termination Date shall deliver signed counterparts of such letter to
the Company and the Agent no later than 21 days after the date of such request
by the Company. Any Bank which does not deliver such counterparts by the 21st
day after such request shall be deemed to have declined to extend the scheduled
Revolving Termination Date. If all Banks consent to the requested extension of
the scheduled Revolving Termination Date, the scheduled Revolving Termination
Date shall be extended for an additional 364 days on the previously- scheduled
Revolving Termination Date (and the Agent shall notify the Company and the Banks
of such extension). If all Banks do not consent to the requested extension of
the scheduled Revolving Termination Date, the scheduled Revolving Termination
Date shall not be extended.

                                   ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.1.     TAXES.

                  (a) Any and all payments by the Borrowers to each Bank, Tax
Transferee or the Agent under this Agreement and any other Loan Document shall
be made free and clear of, and without deduction or withholding for any Taxes.
In addition, the Borrowers shall pay all Other Taxes.

                  (b) The Borrowers agree to indemnify and hold harmless each
Bank and the Agent for the full amount of Taxes or Other Taxes (including any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section) paid by the Bank or the Agent and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. Payment under this indemnification shall be made within 30 days after
the date the Bank or the Agent makes written demand therefor.

                  (c) If the Borrowers shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Bank, Tax Transferee or the Agent, then:

                  (i) the sum payable shall be increased as necessary so that
         after making all required deductions and withholdings (including
         deductions and withholdings applicable to additional sums payable under
         this Section) such Bank, Tax Transferee or the Agent, as the case may
         be, receives an amount equal to the sum it would have received had no
         such deductions or withholdings been made;

                  (ii) the Borrowers shall make such deductions and
         withholdings;

                  (iii) the Borrowers shall pay the full amount deducted or
         withheld to the relevant taxing authority or other authority in
         accordance with applicable law; and

                  (iv) the Borrowers shall also pay to each Bank, Tax Transferee
         or the Agent for the account of such Bank or Tax Transferee, at the
         time interest is paid, all additional amounts which the respective Bank
         specifies as necessary to preserve the after-tax yield



                                       35

         the Bank or Tax Transferee would have received if such Taxes or Other
         Taxes had not been imposed.

                  (d) Within 30 days after the date of any payment by the
Borrowers of Taxes or Other Taxes, the Borrowers shall furnish the Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment satisfactory to the Agent.

                  (e) Within 30 days after the date that any Bank, Tax
Transferee or the Agent receives a refund of any Taxes or Other Taxes for which
it has been indemnified by the Borrowers pursuant to this Agreement (other than
through potential use of such Taxes as a Foreign tax credit on a tax return
filed by such Bank, Tax Transferee or Agent), such Bank, Tax Transferee or the
Agent, as the case may be, shall pay to the applicable Borrower such refund of
Taxes or Other Taxes. Notwithstanding the foregoing, such Bank, Tax Transferee
or the Agent shall not be required to make any payment hereunder before such
time as the Borrowers shall have made all payments or indemnities then due
pursuant to this Agreement; PROVIDED HOWEVER, that such Bank, Tax Transferee or
the Agent shall be required to make such payments promptly after such time as
the Borrowers shall have made all such payments or indemnities.

                  (f) Notwithstanding anything to the contrary herein, the
Borrowers shall not be required to indemnify any Bank or Tax Transferee or pay
any additional amounts to any Bank or Tax Transferee pursuant to this SECTION
3.1 to the extent that such additional amounts are attributable to a
determination by the Internal Revenue Service that such Bank or Tax Transferee
is a "conduit entity" participating in a "conduit financing arrangement" within
the meaning of Treas. Reg. ss.1.881-3.

         3.2.     ILLEGALITY.

                  (a) If the introduction of any Requirement of Law, or any
change in any Requirement of Law, or in the interpretation or administration of
any Requirement of Law, in each case occurring after the Effective Date, has
made it unlawful, or that any central bank or other Governmental Authority has
asserted that it is unlawful, for any Bank or its applicable Lending Office, to
make Offshore Rate Loans, then, on notice thereof by the Bank to the Borrowers
through the Agent, any obligation of that Bank to make Offshore Rate Loans shall
be suspended until the Bank notifies the Agent and the Borrowers that the
circumstances giving rise to such determination no longer exist.

                  (b) If it is unlawful to maintain any Offshore Rate Loan, the
Borrowers shall, upon receipt of notice of such fact



                                       36

<PAGE>   42



and demand from such Bank (with a copy to the Agent), prepay in full such
Offshore Rate Loans of that Bank then outstanding, together with interest
accrued thereon and amounts required under SECTION 3.4, either on the last day
of the Interest Period thereof, if the Bank may lawfully continue to maintain
such Offshore Rate Loans to such day, or immediately, if the Bank may not
lawfully continue to maintain such Offshore Rate Loan. If a Borrower is required
to so prepay any Offshore Rate Committed Loan, then concurrently with such
prepayment, such Borrower shall borrow from the affected Bank, in the amount of
such repayment, a Base Rate Committed Loan.

         3.3.     INCREASED COSTS AND REDUCTION OF RETURN.

                  (a) If due to either (i) the introduction of or any change
(other than any change by way of imposition of or increase in reserve
requirements included in the calculation of the Offshore Rate) in or in the
interpretation of any law or regulation or (ii) the compliance by that Bank with
any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to such Bank of agreeing to make or making, funding or maintaining any
Offshore Rate Committed Loans, then the Borrowers shall be liable for, and shall
from time to time, upon demand (with a copy of such demand to be sent to the
Agent), pay to the Agent for the account of such Bank, additional amounts as are
sufficient to compensate such Bank for such increased costs.

                  (b) If (i) the introduction of any Capital Adequacy
Regulation, (ii) any change in any Capital Adequacy Regulation, (iii) any change
in the interpretation or administration of any Capital Adequacy Regulation by
any central bank or other Governmental Authority charged with the interpretation
or administration thereof, or (iv) compliance by the Bank (or its Lending
Office) or any corporation controlling the Bank with any Capital Adequacy
Regulation, in each case (A) not currently scheduled to become effective and (B)
occurring after the Effective Date, affects or would affect the amount of
capital required or expected to be maintained by the Bank or any corporation
controlling the Bank and (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy) determines that the
amount of such capital is increased as a consequence of its Commitments, loans,
credits or obligations under this Agreement, then, upon demand of such Bank to
the Borrowers through the Agent, the Borrowers shall pay to the Bank, from time
to time as specified by the Bank, additional amounts sufficient to compensate
the Bank for such increase.

         3.4.     FUNDING LOSSES. The Borrowers shall reimburse each Bank and
hold each Bank harmless from any loss or expense which the Bank may sustain or
incur as a consequence of:

                  (a) the failure of the Borrowers to make on a timely basis any
payment of principal of any Offshore Rate Loan;

                  (b) the failure of the Borrowers to borrow, continue or
convert an Offshore Rate Committed Loan after the Borrowers have given (or is
deemed to have given) a Notice of Borrowing or a Notice of Conversion/
Continuation;

                  (c) the failure of the Borrowers to make any prepayment of any
Offshore Rate Committed Loan in accordance with any notice delivered under
SECTION 2.6;

                  (d) the prepayment (including pursuant to SECTION 2.6) or
other payment (including after acceleration thereof) of any Offshore Rate Loan
on a day that is not the last day of the relevant Interest Period; or

                  (e) the automatic conversion under SECTION 2.4(a) of any
Offshore Rate Committed Loan to a Base Rate Committed Loan on a day that is not
the last day of the relevant Interest Period; including any such loss or expense
arising from the liquidation or reemployment of funds obtained by it to maintain
its Offshore Rate Loans or from fees payable to terminate the deposits from
which such funds were obtained. For purposes of calculating amounts payable by
the Borrowers to the Banks under this Section and under SECTION 3.3(a), each
Offshore Rate Committed Loan made by a Bank (and each related reserve, special
deposit or similar requirement) shall be conclusively deemed to have been funded
at the IBOR used in determining the Offshore Rate for such Offshore Rate Loan by
a matching deposit or other borrowing in the interbank eurodollar market for a
comparable amount and for a comparable period, whether or not such Offshore Rate
Loan is in fact so funded.

         3.5. INABILITY TO DETERMINE RATES. If the Majority Banks and the Agent
determine that for any reason adequate and reasonable means do not exist for
determining the Offshore Rate for any requested Interest Period with respect to
a proposed Offshore Rate Loan or dollar deposits in the relevant amount and for
the relevant Interest Period are not available to BofA in the interbank
Eurodollar market, the Agent will promptly so notify the Borrowers and each
Bank. Thereafter, the obligation of the Banks to make or maintain Offshore Rate
Loans hereunder shall be suspended until the Agent upon the instruction of the
Majority Banks revokes such notice in writing. Upon receipt of such notice, the
Borrowers may revoke any Notice of Borrowing or



                                       38

<PAGE>   44



Notice of Conversion/Continuation then submitted by them. If the Borrowers do
not revoke such Notice, the Banks shall make, convert or continue the Committed
Loans, as proposed by a Borrower, in the amount specified in the applicable
notice submitted by such Borrower, but such Committed Loans shall be made,
converted or continued as Base Rate Committed Loans instead of Offshore Rate
Committed Loans.

         3.6.     CERTIFICATES OF BANKS. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Borrowers (with a copy
to the Agent) a certificate setting forth in reasonable detail the amount
payable to the Bank hereunder and such certificate shall be conclusive and
binding on the Borrowers in the absence of manifest error.

         3.7.     SUBSTITUTION OF BANKS. Upon the receipt by the Borrowers from
any Bank (an "Affected Bank") of a claim for compensation under SECTION 3.1 or
SECTION 3.3 or in the event any Bank whose obligations to make Offshore Loans
have been suspended under SECTION 3.2, the Borrowers may: (i) request the
Affected Bank to use its reasonable efforts to obtain a replacement bank or
financial institution satisfactory to the Borrowers to acquire and assume all or
a ratable part of all of such Affected Bank's Loans and Commitment (a
"Replacement Bank"); (ii) request one more of the other Banks to acquire and
assume all or part of such Affected Bank's Loans and Commitment; or (iii)
designate a Replacement Bank. Any such designation of a Replacement Bank under
clause (i) or (iii) shall be subject to the prior written consent of the Agent
(which consent shall not be unreasonably withheld).

         3.8.     AFFECTED BANK'S OBLIGATION TO MITIGATE. Each Bank agrees that,
as promptly as practicable after it becomes aware of the occurrence of an event
or the existence of a condition that would cause (a) a Borrower to be required
to pay additional amounts to it under SECTION 3.1 (b) or (c) or (b) it to be
illegal for such Bank to make or maintain any Offshore Rate Loan, it will, to
the extent not inconsistent with such Bank's internal policies, use its
reasonable efforts to make, fund or maintain the affected Loans of such Bank
through another Lending Office of such Bank if as a result thereof the
additional moneys which would otherwise be required to be paid in respect of
such Loans pursuant to SECTION 3.1(c) would be materially reduced or the
illegality or other adverse circumstances which would otherwise require
prepayment of such Loans pursuant to SECTION 3.2, and if, as such Bank
determines, in its sole discretion, the making, funding or maintaining of such
Loans through such Lending Office would not otherwise materially adversely
affect such Loans or such Bank. The Borrowers hereby agree to pay all reasonable
expenses incurred by any Bank in utilizing another Lending Office pursuant to
this SECTION 3.8.



                                       39

<PAGE>   45



         3.9.     PRESENTATION OF CLAIMS; SURVIVAL. Each Bank will promptly
notify the Company and the Agent of any event of which it has knowledge,
occurring after the Effective Date, which will entitle such Bank to compensation
pursuant to this Article III (each, a "TRIGGER EVENT"). Notwithstanding any
other provision of this Article III, no Bank shall be entitled to any
compensation pursuant to this Article in respect of any Trigger Event for any
period of time in excess of 6 months prior to such notice unless such Trigger
Event is retroactive and notice is given within 6 months of such retroactive
Trigger Event.

such licenses, permits, and other approvals would be reasonably likely to have a
Materially Adverse Effect. Each other Obligor is a corporation duly incorporated
or partnership duly formed, validly existing and in good standing under the laws
of the jurisdiction of its incorporation or formation (to the extent applicable

any Organization Document or material Contractual Obligation of the Company or
such Obligor or any law or governmental regulation or court decree or order
(and, in the case of any such material Contractual Obligation or any such law,
regulation, decree or order, such conflict, violation or default would not be
reasonably likely to have a Materially Adverse Effect) and will not result in or
require the creation or imposition of any Lien on any of the Company's or such
Obligor's properties having an aggregate value in excess of $500,000 pursuant to
the provisions of any Contractual Obligation (other than under this Agreement).

or is to be a party will, on the due execution and delivery thereof, constitute

                  (b) individually or in the aggregate would reasonably be
expected to result in or constitute a Materially Adverse Effect, except as
disclosed in ITEM 5.7 ("Litigation") of the Disclosure Schedule;

and none of the Company and the other Obligors is subject, to the best knowledge
of the Company, to any arbitration proceedings under collective bargaining
agreements or otherwise or any governmental investigations or inquiries which

to result in or constitute a Materially Adverse Effect.

principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying margin stock, and less than 25%
of the assets of either Borrower, individually and on a consolidated basis with
its Subsidiaries, consists of margin stock. The proceeds of any Loans made

                  (a) Each Plan is in compliance in all material respects with
the applicable provisions of ERISA, the Code and other federal or state law.
Each Plan which is intended to qualify under Section 401(a) of the Code has
received a favorable determination letter from the IRS and to the best knowledge
of the Company, nothing has occurred which would cause the loss of such
qualification. The Company and each ERISA Affiliate has made all required
contributions to any Plan subject to Section 412 of the Code, and no application
for a funding waiver or an extension of any amortization period pursuant to
Section 412 of the Code has been made with respect to any Plan.

                  (b) There are no pending or, to the best knowledge of Company,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan which has resulted or could reasonably be expected to
result in a Material Adverse Effect. There has been no prohibited transaction or
violation of the fiduciary responsibility rules with respect to any Plan which
has resulted or could reasonably be expected to result in a Materially Adverse
Effect.

                  (c) (i) No ERISA Event has occurred or is reasonably expected
to occur; (ii) no Pension Plan has any Unfunded Pension Liability; (iii) neither
the Company nor any ERISA Affiliate has incurred, or reasonably expects to
incur, any liability under Title IV of ERISA with respect to any Pension Plan
(other than premiums due and not delinquent under Section 4007 of ERISA); (iv)
neither the Company nor any ERISA Affiliate has incurred, or reasonably expects
to incur, any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under
Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan; and (v)
neither the Company nor any ERISA Affiliate has engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA.

         5.10.    SUBSIDIARIES. The Obligors have no Subsidiaries except those
listed on ITEM 5.10 ("Subsidiaries") of the Disclosure Schedule and those
Subsidiaries which are permitted to have been acquired after the Effective Date
in accordance with the terms hereof.

         5.11.    TAXES. Each of the Company and each other Obligor has filed
all Federal and all other material tax returns and reports required by law to
have been filed by it; all such tax returns are complete and accurate in all
material respects; and the Company and each other Obligor has paid or properly
accrued for or withheld (as applicable) all taxes and governmental charges
thereby shown to be owing or required to be withheld, except any such taxes or
charges which are being diligently contested in good faith by appropriate
proceedings and for which



                                       47

<PAGE>   53



adequate reserves in accordance with GAAP shall have been set aside on its
books.

         5.12.    ABSENCE OF DEFAULT. Neither the Company nor any other Obligor
is in default under any governmental regulation or court decree or order or
under any law if such default would be reasonably likely to have a Materially
Adverse Effect.

         5.13.    LABOR CONTROVERSIES. There are no labor controversies pending
or, to the best knowledge of the Company, threatened against the Company or any
other Obligor, which would be reasonably likely to have a Materially Adverse
Effect.

         5.14.    OWNERSHIP OF PROPERTIES. Each of the Company and each other
Obligor has good and marketable title to, or a valid leasehold interest in, all
of its properties and assets, real and personal, of any nature whatsoever, free
and clear of all Liens, except as permitted pursuant to SECTION 6.2.3 and, as of
the Effective Date, as disclosed in ITEM 6.2.2(L)/6.2.3(A) ("Existing
Indebtedness and Existing Liens") of the Disclosure Schedule and except for
defects to title which have not had and would not, individually or in the
aggregate, reasonably be expected to have a Materially Adverse Effect.

         5.15.    PATENTS, TRADEMARKS, ETC. Each of the Company and each other
Obligor owns and possesses all such patents, patent rights, trademarks,
trademark rights, trade names, trade name rights, service marks, service mark
rights and copyrights as the Company considers necessary for the conduct of the
businesses of the Company and the other Obligors as now conducted without, to
the best knowledge of the Company after due inquiry, any infringement upon
rights of other Persons, except as may be disclosed in ITEM 5.15 ("Patent and
Trademark Infringements") of the Disclosure Schedule.

         5.16.    ENVIRONMENTAL MATTERS. The Company conducts in the ordinary
course of business a review of the effect of existing Environmental Laws and
existing Environmental Claims on its business, operations and properties, and as
a result thereof the Company has reasonably concluded that, except as
specifically disclosed in ITEM 5.16 ("Environmental Matters") of the Disclosure
Schedule, such Environmental Laws and Environmental Claims could not,
individually or in the aggregate, reasonably be expected to have a Materially
Adverse Effect.

         5.17.    ACCURACY OF INFORMATION. All factual information (taken as a
whole) heretofore or contemporaneously furnished by or on behalf of the Company
or any other Obligor in writing to any Bank for purposes of or in connection
with this Agreement or any transaction contemplated hereby is, and all other
such



                                       48

<PAGE>   54



factual information (taken as a whole) hereafter furnished by or on behalf of
the Company or any other Obligor in writing to the Agent or any Bank will be,
true and accurate in every material respect on the date as of which such
information is dated or certified.

         5.18.    YEAR 2000 REPRESENTATIONS. On the basis of a comprehensive
review and assessment of Company's systems and equipment and inquiry made of
Company's material suppliers, vendors and customers, the Company reasonably
believes that the "Year 2000 problem" (that is, the inability of computers, as
well as embedded microchips in non-computing devices, to perform properly
date-sensitive functions with respect to certain dates prior to and after
December 31, 1999), including costs of remediation, will not have a Materially
Adverse Effect. The Company has developed feasible contingency plans adequate to
ensure uninterrupted and unimpaired business operation in the event of failure
of its own or, to the extent within the Company's control, a third party's
systems or equipment due to the Year 2000 problem, including those of vendors,
customers, and suppliers, as well as a general failure of or interruption in its
communications and delivery infrastructure.

         5.19.    HEALTH CARE REGULATORY MATTERS.

                  (a) Except as disclosed in ITEM 5.19 ("Regulatory Matters") of
the Disclosure Schedule and except to the extent that the failure to obtain or
maintain any of the items in clauses (i) through (iv) below would not be
material to the conduct of the Company's business, each Facility or the
appropriate Subsidiary, as the case may be, has:

                  (i) where required by Applicable Law, obtained all required
         CONs for the construction or expansion of or investment in such
         Facility;

                  (ii) obtained and maintains all Health Facility Licenses
         necessary to operate such Facility as a long-term care facility;

                  (iii) obtained and maintains Medicaid Certification and
         Medicare Certification with respect to such Facility;

                  (iv) entered into and maintains its Medicaid Provider
         Agreement and its Medicare Provider Agreement with respect to such
         Facility; and

                  (v) not received, to the knowledge of the Company, any
         Hill-Burton Act funds nor has any



                                       49

<PAGE>   55



         obligations with respect to Hill-Burton Act charity
         care.

                  (b) Except as disclosed in ITEM 5.19 ("Regulatory Matters") of
the Disclosure Schedule, all necessary steps have been or are being taken to
secure the renewal of any Health Facility License, Medicaid Provider Agreement
or Medicare Provider Agreement issued with respect to any Facility that is to
expire within 60 days after the date hereof and that is material to the conduct
of the Company's business, and there is no reasonable basis known to the Company
or its Subsidiaries that any such renewal will not be obtained.

                  (c) Except as disclosed in ITEM 5.19 ("Regulatory Matters") of
the Disclosure Schedule, there are no proceedings pending, or, to the best of
the Company's knowledge, threatened by any Governmental Authority seeking to
modify, revoke or suspend any Health Facility License, Medicaid Provider
Agreement, Medicare Provider Agreement, Medicare Certification or Medicaid
Certification with respect to any Facility, which would be reasonably likely to
have a Materially Adverse Effect. Since the date of the most recent Medicare
Certification and Medicaid Certification with respect to each Facility, none of
the Company or any Subsidiary has taken any action that would materially
adversely affect such Certification or the Medicare Provider Agreement or
Medicaid Provider Agreement with respect to such Facility.

         5.20.    MERGER AGREEMENT.

                  (a) Consummation of the transactions contemplated by the
Merger Agreement by the Company and Manor Care has not and will not:

                  (i) contravene the terms of any of that Person's
         Organization Documents;

                  (ii) result in a breach or contravention of, or the creation
         of any Lien under, any document evidencing any material Contractual
         Obligation to which such Person is a party or any order, injunction,
         writ or decree of any Governmental Authority to which such Person or
         its property is subject, except where the breach, continuation or
         creation would neither materially impair the ability of Manor Care to
         consummate the transactions contemplated by the Merger Agreement nor
         have a Material Adverse Effect (as defined in the Merger Agreement) on
         the Company or Manor Care; or




                                       50

<PAGE>   56



                  (iii) violate a Requirement of Law, except where the violation
         would neither materially impair the ability of Manor Care to consummate
         the transactions contemplated by the Merger Agreement nor have a
         Material Adverse Effect (as defined in the Merger Agreement) on the
         Company or Manor Care.

                  (b) The Merger Agreement constitutes the legal, valid and
binding obligations of the Company and, to the Company's knowledge, Manor Care,
enforceable against such Person in accordance with their respective terms,
except as enforceability may be limited by applicable bankruptcy, insolvency, or
similar laws affecting the enforcement of creditors' rights generally or by
equitable principles relating to enforceability.

<PAGE>   58



         GAAP consistently applied, certified by the principal accounting or
         financial Responsible Officer of the Company, and

                  (ii) a Compliance Certificate, including computation of the

Subsidiaries as of the dates and for the periods stated therein, subject, in the
case of unaudited financial statements, to changes resulting from normal
year-end audit adjustments (none of which would, alone or in the aggregate, have
a Materially Adverse Effect).

         6.1.2.   MAINTENANCE OF EXISTENCES, ETC. Except as expressly otherwise
permitted by SECTION 6.2.6 or 6.2.7, the Company will:

                  (a) cause to be done at all times all things necessary to
maintain and preserve the existences, rights (statutory and other) and
franchises (including licenses, authorizations and permits necessary to the
operation of its businesses) of the Company, the other Obligors and their
respective Subsidiaries, in the case of the Company as a corporation and in the
case of each



                                       53

<PAGE>   59



other Obligor and each such Subsidiary as a partnership or corporation or other
business entity, as the case may be, unless the failure so to do in any case
could not reasonably be expected to have a Materially Adverse Effect; and

                  (b) as of the Effective Date and thereafter, continue to own
and hold, directly or indirectly, free and clear of all Liens (except for the
Liens permitted by clauses (c), (e) and (f) of SECTION 6.2.3), all of the

         6.1.3.   FOREIGN QUALIFICATION. The Company will, and will cause each
other Obligor and each Subsidiary of the Obligors to, cause to be done at all
times all things necessary to be duly qualified to do business and be in good

partnerships in any such jurisdiction) in each jurisdiction where the failure so
to qualify would reasonably be expected to have a Materially Adverse Effect.

         6.1.4.   PAYMENT OF TAXES, ETC. The Company will, and will cause each
other Obligor and each Subsidiary of the Obligors to, pay and discharge, as the
same may become due and payable, all Federal, state, local and foreign taxes,
assessments, fees and other governmental charges or levies against it or on any
of its property or the income or profits therefrom, in excess of $500,000 in the
aggregate; PROVIDED that the foregoing shall not require the Company or any
other Obligor or Subsidiary to pay or discharge any such tax, assessment, fee,
charge or levy so long as it shall be diligently contesting the validity thereof
in good faith by appropriate proceedings and shall have set aside on its books
adequate reserves in accordance with GAAP with respect thereto.

         6.1.5.   INSURANCE. The Company will, and will cause each other Obligor
and each Subsidiary of the Obligors to, maintain, with reputable, financially
sound insurance companies, insurance with respect to its properties and business
against such casualties and contingencies and of such types and in such amounts
as is customary in accordance with prudent business practice in the case of
similar businesses in similar locations and will from time to time upon the
reasonable request of the Agent, furnish a certificate of a Responsible Officer
of the Company setting forth the nature and extent of all insurance maintained
by the Company, the other Obligors and their Subsidiaries in accordance with
this SECTION 6.1.5.

         6.1.6.   NOTICE OF DEFAULT, LITIGATION, ETC. The Company will give
prompt notice (but in no event later than ten days after any Responsible Officer
of the Company has or should



                                       54

<PAGE>   60



reasonably have obtained knowledge thereof) (with a description in reasonable
detail of the nature and period of existence thereof and of the actions which
the Company has taken and proposes to take with respect thereto) to the Agent

                  (a) the occurrence of any Default;

                  (b) any litigation, arbitration or governmental investigation
or proceeding not previously disclosed by the Company to the Banks which has
been instituted or, to the knowledge of the Company, is threatened against, the
Company or any other Obligor or any of their Subsidiaries or to which any of its
properties, assets or revenues is subject which

                  (i) would be reasonably likely to have a
         Materially Adverse Effect, or

                  (ii) relates to this Agreement or any other Loan Document;

                  (c) the occurrence of any other circumstance of which any of
the officers of the Company has knowledge and which has a reasonable likelihood
of resulting in a Materially Adverse Effect;

litigation, arbitration or governmental investigation or proceeding previously
disclosed by the Company to the Banks; and

                  (e) of the occurrence of any of the following events affecting
the Company or any ERISA Affiliate:

                  (i) an ERISA Event;

         to, any Plan subject to Section 412 of the Code by the Company or any
         ERISA Affiliate; or

                  (iv) the adoption of any amendment to a Plan subject to
         section 412 of the Code, if such amendment results in a material
         increase in contributions or Unfunded Pension Liability.

         6.1.7.  PERFORMANCE OF OBLIGATIONS.  The Company will, and
will cause each other Obligor and each Subsidiary of the Obligors
to, (a) perform promptly and faithfully all of its Obligations



                                       55

<PAGE>   61



under each Loan Document executed by it and (b) comply with the provisions of
all contracts or agreements to which it is a party or by which it is bound,
whether oral or written, express or implied, and pay all obligations which it
has incurred or may incur pursuant to any such contract or agreement as such
obligations become due, where the failure so to comply or make such payment
would, individually or in the aggregate with all such other failures, have a
Materially Adverse Effect.

         6.1.8. BOOKS AND RECORDS. The Company will, and will cause each other
Obligor and each Subsidiary of the Obligors to, keep proper books and records
reflecting all of its business affairs and transactions so that its consolidated
financial statements are in accordance with GAAP and permit the Agent and the
Banks, on reasonable notice and at reasonable times and intervals during
ordinary business hours, to visit all of its offices, discuss its financial
matters with officers of any Obligor or any Subsidiary of the Obligors and its
independent public accountants, and examine and make abstracts from any of its
books or other corporate records. The Company shall pay any reasonable fees of
such independent public accountants incurred in connection with the exercise by
the Agent and the Banks of their rights pursuant to this SECTION 6.1.8.

         6.1.9. COMPLIANCE WITH LAWS, ETC. The Company will, and will cause each
other Obligor and each Subsidiary of the Obligors to, comply with the
requirements of all Applicable Laws (including, without limitation,
Environmental Laws) noncompliance with which would reasonably be expected to
have a Materially Adverse Effect.

         6.1.10. MANOR CARE OBLIGORS. The Company will cause each Manor Care
Obligor to execute and deliver to the Agent for the benefit of the Banks on or
before October 31, 1998:

                  (ii) copies of resolutions, incumbency certificates
         organizational documents and good standing certificates responsive to
         the requirements of clauses (b) and (c) of SECTION 4.1. or such other
         evidence reasonably satisfactory to the Agent; and

                  (iii) a legal opinion of R. Jeffrey Bixler, general counsel to
         the Manor Care Obligors, in the form of EXHIBIT D or otherwise
         satisfactory to the Agent.

In addition, the Company will use reasonable efforts to cause each Manor Care
Obligor to become a party to the Guaranty by



                                       56

<PAGE>   62



executing and delivering to the Agent for the benefit of the Banks an Assumption
Agreement in the form of Exhibit 1 to the Guaranty.

         6.1.11. MAINTENANCE OF PROPERTY. The Company will, and will cause each
other Obligor and each Subsidiary of the Obligors to, at their joint and several
expense, maintain and keep its properties which are used or useful to its
business in good repair, working order and condition (except for ordinary wear
and tear), and from time to time make all necessary or desirable repairs,
renewals and replacements, so that its businesses may be properly and
advantageously conducted at all times.

any Obligor which remain in effect for more than 60 days.

         7.1.9.   IMPERMISSIBLE CHANGE IN CONTROL. Any Impermissible Change in
Control shall occur.

         7.1.10.  GUARANTOR DEFAULTS. Any Obligor fails in any material respect
to perform or observe any term, covenant or agreement in the Guaranty or, if
applicable, the Manor Care Subsidiary Guaranty subject, in each case, to the
grace periods set forth in this Article VII that would otherwise be applicable
to the Company; or the Guaranty or the Manor Care Subsidiary Guaranty is for any
reason partially (including with respect to future advances) or wholly revoked
or invalidated, or otherwise ceases to be in full force and effect, or any
Obligor or any other Person contests in any manner the validity or
enforceability thereof or denies that it has any further liability or obligation
thereunder.

         7.1.11.  LOSS OF LICENSES. Any Governmental Authority revokes or fails
to renew any material license, permit or franchise of the Company or any
Subsidiary, or the Company or any Subsidiary for any reason loses any material
license, permit or franchise, or the Company or any Subsidiary suffers the
imposition of any restraining order, escrow, suspension or impound of funds in
connection with any proceeding (judicial or administrative) with respect to any
material license, permit or franchise, in each case which would be reasonably
likely to have a Materially Adverse Effect.

         7.2.     REMEDIES.  If any Event of Default occurs, the Agent
shall, at the request of, or may, with the consent of, the
Majority Banks,

                  (a) declare the commitment of each Bank to make Loans to be
terminated, whereupon such commitments shall be terminated;

                  (b) declare the unpaid principal amount of all outstanding
Loans, all interest accrued and unpaid thereon, and all other amounts owing or
payable hereunder or under any other Loan Document to be immediately due and
payable, without presentment, demand, protest or other notice of any kind, all
of which are hereby expressly waived by the Company; and

                  (c) exercise on behalf of itself and the Banks all rights and
remedies available to it and the Banks under the Loan Documents or applicable
law;

provided, however, that upon the occurrence of any event specified in clauses
(a) through (d) of SECTION 7.1.4, the obligation of each Bank to make Loans
shall automatically terminate and the unpaid principal amount of all outstanding
Loans and all interest and other amounts as aforesaid shall



                                       68

<PAGE>   74



automatically become due and payable without further act of the Agent or any
Bank.

         7.3.    RIGHTS NOT EXCLUSIVE. The rights provided for in this Agreement
and the other Loan Documents are cumulative and are not exclusive of any other
rights, powers, privileges or remedies provided by law or in equity, or under
any other instrument, document or agreement now existing or hereafter arising.


                                  ARTICLE VIII

                                    THE AGENT

         8.1.    APPOINTMENT AND AUTHORIZATION. Each Bank hereby irrevocably
(subject to SECTION 9.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.

         8.2.    DELEGATION OF DUTIES. The Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

         8.3.    LIABILITY OF AGENT. None of the Agent-Related Persons shall
(i) be liable to the Banks for any action taken or omitted to be taken by any of
them under or in connection with this Agreement or any other Loan Document or
the transactions contemplated hereby (except for its own gross negligence or
willful misconduct), or (ii) be responsible in any manner to any of the Banks
for any recital, statement, representation or warranty made by the Company or
any Subsidiary or Affiliate of the Company, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Agent under or in connection with, this Agreement



                                       69

<PAGE>   75



or any other Loan Document, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of the Company or any other party to any Loan Document to
perform its obligations hereunder or thereunder. No Agent- Related Person shall
be under any obligation to any Bank to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Company or any of the Company's Subsidiaries or
Affiliates.

         8.4.     RELIANCE BY AGENT.

                  (a) The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Borrowers), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the Majority Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Loan Document in accordance with a request or consent of the Majority
Banks and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Banks.

                  (b) For purposes of determining compliance with the conditions
specified in SECTION 4.1, each Bank that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Bank for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Bank.

         8.5.     NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Banks, unless the Agent shall
have received written notice from a Bank or the Borrowers referring to this
Agreement, describing such Default or Event of Default and



                                       70

<PAGE>   76



stating that such notice is a "notice of default". The Agent will notify the
Banks of its receipt of any such notice. The Agent shall take such action with
respect to such Default or Event of Default as may be requested by the Majority
Banks in accordance with Article VII; PROVIDED, HOWEVER, that unless and until
the Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Banks.

         8.6.     CREDIT DECISION. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, and all applicable bank regulatory laws relating
to the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Company and its Subsidiaries
hereunder. Each Bank also represents that it will, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company.
Except for notices, reports and other documents expressly herein required to be
furnished to the Banks by the Agent, the Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of the Company which may come into the possession
of any of the Agent-Related Persons.

         8.7.     INDEMNIFICATION OF AGENT. Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrowers and without limiting the obligation of the Borrowers to do so), pro
rata, from and against any and all Indemnified Liabilities; PROVIDED, HOWEVER,
that no Bank shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified



                                       71

<PAGE>   77



Liabilities resulting solely from such Person's gross negligence or willful
misconduct. Without limitation of the foregoing, each Bank shall reimburse the
Agent upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by the Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,
any other Loan Document, or any document contemplated by or referred to herein,
to the extent that the Agent is not reimbursed for such expenses by or on behalf
of the Borrowers. The undertaking in this Section shall survive the payment of
all Obligations hereunder and the resignation or replacement of the Agent.

         8.8.     AGENT IN INDIVIDUAL CAPACITY. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent hereunder and
without notice to or consent of the Banks. The Banks acknowledge that, pursuant
to such activities, BofA or its Affiliates may receive information regarding the
Company or its Affiliates (including information that may be subject to
confidentiality obligations in favor of the Company or such Subsidiary) and
acknowledge that the Agent shall be under no obligation to provide such
information to them. With respect to its Loans, BofA shall have the same rights
and powers under this Agreement as any other Bank and may exercise the same as
though it were not the Agent, and the terms "Bank" and "Banks" include BofA in
its individual capacity.

         8.9.     SUCCESSOR AGENT. The Agent may, and at the request of the
Majority Banks shall, resign as Agent upon 60 days' notice to the Banks and the
Company. If the Agent resigns under this Agreement, the Majority Banks shall
appoint from among the Banks a successor agent for the Banks which successor
agent shall be approved by the Company (which approval shall not be unreasonably
withheld or delayed). If no successor agent is appointed prior to the effective
date of the resignation of the Agent, the Agent may appoint, after consulting
with the Banks and the Company, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this Article VIII and
SECTIONS 9.4 and 9.5 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this



                                       72

<PAGE>   78



Agreement. If no successor agent has accepted appointment as Agent by the date
which is 30 days following a retiring Agent's notice of resignation, the
retiring Agent's resignation shall nevertheless thereupon become effective and
the Banks shall perform all of the duties of the Agent hereunder until such
time, if any, as the Majority Banks appoint a successor agent as provided for
above.

         8.10.    WITHHOLDING TAX.

                  (a) If any Non-U.S. Bank claims exemption from, or a reduction
of, U.S. withholding tax under Sections 1441 or 1442 of the Code, such Non-U.S.
Bank agrees with and in favor of the Borrowers and the Agent, to deliver to the
Borrowers and the Agent:

                  (i) if such Non-U.S. Bank claims an exemption from, or a
         reduction of, withholding tax under a United States tax treaty,
         properly completed IRS Forms 1001 and W-8 or any successor form, before
         the payment of any interest in the first calendar year and before the
         payment of any interest in each third succeeding calendar year during
         which interest may be paid under this Agreement or such other time as
         may be required by any change in law if so requested by the Borrowers;

                  (ii) if such Non-U.S. Bank claims that interest paid under
         this Agreement is exempt from United States withholding tax because it
         is effectively connected with a United States trade or business of such
         Non-U.S. Bank, two properly completed and executed copies of IRS Form
         4224 or any successor form before the payment of any interest is due in
         the first taxable year of such Non-U.S. Bank and in each succeeding
         taxable year of such Non-U.S. Bank during which interest may be paid
         under this Agreement or such other time as may be required by any
         change in law if so requested by the Borrowers, and IRS Form W-9; and

                  (iii) such other form or forms as may be required under the
         Code or other laws of the United States as a condition to exemption
         from, or reduction of, United States withholding tax.

Such Non-U.S. Bank agrees to promptly notify the Borrowers and the Agent of any
change in circumstances which would modify or render invalid any claimed
exemption or reduction.

                  (b) If any Non-U.S. Bank claims exemption from, or reduction
of, withholding tax under a United States tax treaty by



                                       73

<PAGE>   79



providing IRS Form 1001 and such Non-U.S. Bank sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Borrowers to such Non-U.S. Bank, such Non- U.S. Bank agrees to notify the
Borrowers and the Agent of the percentage amount in which it is no longer the
beneficial owner of Obligations of the Borrowers to such Non-U.S. Bank. To the
extent of such percentage amount, the Borrowers and the Agent will treat such
IRS Form 1001 as no longer valid.

                  (c) If any Non-U.S. Bank claiming exemption from United States
withholding tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Borrowers to such Non-U.S. Bank, such Non-U.S. Bank agrees to undertake sole
responsibility for complying with the withholding tax requirements imposed by
Sections 1441 and 1442 of the Code.

                  (d) If any Non-U.S. Bank is entitled to a reduction in the
applicable withholding tax, the Borrowers and the Agent may withhold from any
interest payment to such Non-U.S. Bank an amount equivalent to the applicable
withholding tax after taking into account such reduction. If the forms or other
documentation required by subsection (a) of this Section are not delivered to
the Borrowers and the Agent, then the Agent may withhold from any interest
payment to such Non-U.S. Bank not providing such forms or other documentation an
amount equivalent to the applicable withholding tax.

                  (e) If the IRS or any other Governmental Authority of the
United States or other jurisdiction asserts a claim that the Agent did not
properly withhold tax from amounts paid to or for the account of any Non-U.S.
Bank (because the appropriate form was not delivered, was not properly executed,
or because such Non-U.S. Bank failed to notify the Borrowers or the Agent of a
change in circumstances which rendered the exemption from, or reduction of,
withholding tax ineffective, or for any other reason) such Non-U.S. Bank shall
indemnify the Borrowers and the Agent fully for all amounts paid, directly or
indirectly, by the Borrowers and the Agent as tax or otherwise, including
penalties and interest, and including any taxes imposed by any jurisdiction on
the amounts payable to the Borrowers and the Agent under this Section, together
with all costs and expenses (including Attorney Costs). The obligation of the
Non-U.S. Banks under this subsection shall survive the payment of all
Obligations and the resignation or replacement of the Agent.

         8.11.    DOCUMENTATION AGENTS AND SYNDICATION AGENT. None of the Banks
identified on the facing page or signature pages of this Agreement as a
"documentation agent" or "syndication agent" shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those



                                       74

<PAGE>   80



applicable to all Banks as such. Without limiting the foregoing, none of the
Banks so identified as a "documentation agent" or "syndication agent" shall have
or be deemed to have any fiduciary relationship with any Bank. Each Bank
acknowledges that it has not relied, and will not rely, on any of the Banks so
identified in deciding to enter into this Agreement or in taking or not taking
action hereunder.


                                   ARTICLE IX

                                  MISCELLANEOUS

         9.1.     AMENDMENTS AND WAIVERS. No amendment or waiver of any
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by the Borrowers therefrom, shall be effective unless
the same shall be in writing and signed by the Majority Banks (or by the Agent
at the written request of the Majority Banks) and the Borrowers and acknowledged
by the Agent, and then any such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; PROVIDED,
HOWEVER, that no such waiver, amendment, or consent shall, unless in writing and
signed by all the Banks and the Borrowers and acknowledged by the Agent, do any
of the following:

                  (a) increase or extend the Commitment of any Bank (or
reinstate any Commitment terminated pursuant to SECTION 7.2);

                  (b) postpone or delay any date fixed by this Agreement or any
other Loan Document for any payment of principal, interest, fees or other
amounts due to the Banks (or any of them) hereunder or under any other Loan
Document;

                  (c) reduce the principal of, or the rate of interest specified
herein on any Loan (except that payment of the default rate of interest under
SECTION 2.8(c) may be waived by Majority Banks), or (subject to clause (ii)
below) any fees or other amounts payable hereunder or under any other Loan
Document;

                  (d) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Loans which is required for the Banks
or any of them to take any action hereunder;

                  (e) amend this Section, or SECTION 2.13, or any provision
herein providing for consent or other action by all Banks; or

                  (f) except as provided in SECTION 6.2.7 or in accordance with
their respective terms, terminate the Guaranty or



                                       75

<PAGE>   81



the Manor Care Subsidiary Guaranty or release a Material Group of Subsidiaries
from their obligations under the Guaranty or the Manor Care Subsidiary Guaranty;

and, PROVIDED FURTHER, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks or all the
Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Loan Document, and (ii) the Fee Letter may be amended, or
rights or privileges thereunder waived, in a writing executed by the parties
thereto.

         9.2.     NOTICES.

                  (a) All notices, requests and other communications shall be in
writing (including, unless the context expressly otherwise provides, by
facsimile transmission, PROVIDED that any matter transmitted by the Borrowers by
facsimile (i) shall be immediately confirmed by a telephone call to the
recipient at the number specified on SCHEDULE 9.2, and (ii) shall be followed
promptly by delivery of a hard copy original thereof) and mailed, faxed or
delivered, to the address or facsimile number specified for notices on SCHEDULE
9.2; or, as directed to the Borrowers or the Agent, to such other address as
shall be designated by such party in a written notice to the other parties, and
as directed to any other party, at such other address as shall be designated by
such party in a written notice to the Borrowers and the Agent.

                  (b) All such notices, requests and communications shall, when
transmitted by overnight delivery, or faxed, be effective when delivered for
overnight (next-day) delivery, or transmitted in legible form by facsimile
machine, respectively, or if mailed, upon the third Business Day after the date
deposited into the U.S. mail, or if delivered, upon delivery; except that
notices pursuant to Article II or VIII shall not be effective until actually
received by the Agent.

                  (c) Any agreement of the Agent and the Banks herein to receive
certain notices by telephone or facsimile is solely for the convenience and at
the request of the Borrowers. The Agent and the Banks shall be entitled to rely
on the authority of any Person purporting to be a Person authorized by the
Borrowers to give such notice and the Agent and the Banks shall not have any
liability to the Borrowers or other Person on account of any action taken or not
taken by the Agent or the Banks in reliance upon such telephonic or facsimile
notice. The obligation of the Borrowers to repay the Loans shall not be affected
in any way or to any extent by any failure by the Agent and the Banks to receive
written confirmation of any telephonic or facsimile notice or the receipt by the
Agent and the Banks of a confirmation which is at variance with the terms
understood by



                                       76

<PAGE>   82



the Agent and the Banks to be contained in the telephonic or facsimile notice.

         9.3.     NO WAIVER; CUMULATIVE REMEDIES. No failure to exercise and no
delay in exercising, on the part of the Agent or any Bank, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

         9.4.     COSTS AND EXPENSES.  The Company shall:

                  (a) whether or not the transactions contemplated hereby are
consummated, pay or reimburse BofA (including in its capacity as Agent) within
five Business Days after demand (subject to SECTION 4.1(g)) for all reasonable
costs and expenses incurred by BofA (including in its capacity as Agent) in
connection with the development, preparation, delivery, administration and
execution of, and any amendment, supplement, waiver or modification to (in each
case, whether or not consummated), this Agreement, any Loan Document and any
other documents prepared in connection herewith or therewith, and the
consummation of the transactions contemplated hereby and thereby, including
reasonable Attorney Costs incurred by BofA (including in its capacity as Agent)
with respect thereto; and

                  (b) pay or reimburse the Agent, the Lead Arranger and each
Bank within five Business Days after demand (subject to SECTION 4.1(g)) for all
costs and expenses (including Attorney Costs) incurred by them in connection
with the enforcement, attempted enforcement, or preservation of any rights or
remedies under this Agreement or any other Loan Document during the existence of
an Event of Default or after acceleration of the Loans (including in connection
with any "workout" or restructuring regarding the Loans, and including in any
Insolvency Proceeding or appellate proceeding).

         9.5.     COMPANY INDEMNIFICATION. Whether or not the transactions
contemplated hereby are consummated, the Borrowers shall indemnify and hold the
Agent-Related Persons, and each Bank and each of its respective officers,
directors, employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including Attorney Costs) of any kind or
nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the
Agent or replacement of any Bank) be imposed on, incurred by or asserted against
any such Person in any way relating to or arising out of



                                       77

<PAGE>   83



this Agreement or any document contemplated by or referred to herein, or the
transactions contemplated hereby, or any action taken or omitted by any such
Person under or in connection with any of the foregoing, including with respect
to any investigation, litigation or proceeding (including any Insolvency
Proceeding or appellate proceeding) related to or arising out of this Agreement
or the Loans or the use of the proceeds thereof, whether or not any Indemnified
Person is a party thereto (all the foregoing, collectively, the "INDEMNIFIED
LIABILITIES"); PROVIDED, that the Borrowers shall have no obligation hereunder
to any Indemnified Person with respect to Indemnified Liabilities resulting from
the gross negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other Obligations.

         9.6.     PAYMENTS SET ASIDE. To the extent that the Borrowers makes a
payment to the Agent or the Banks, or the Agent or the Banks exercise their
right of set-off, and such payment or the proceeds of such set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

         9.7.     SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Borrowers may not assign or
transfer any of their rights or obligations under this Agreement without the
prior written consent of the Agent and each Bank.

         9.8.     ASSIGNMENTS, PARTICIPATIONS, ETC.

                  (a) Any Bank may, with the written consent of the Company at
all times other than during the existence of an Event of Default and the Agent,
which consents shall not be unreasonably withheld, at any time assign and
delegate to one or more Eligible Assignees (provided that no written consent of
the Company or the Agent shall be required in connection with any assignment and
delegation by a Bank to another Bank or to an Eligible Assignee that is an
Affiliate of such Bank) (each an "ASSIGNEE") all, or any ratable part of all, of
the Loans, the Commitments and the other rights and obligations of such Bank
hereunder, in a minimum amount of $10,000,000 or, if less, the



                                       78

<PAGE>   84



entire amount of such Bank's Commitment; PROVIDED, HOWEVER, that the Company and
the Agent may continue to deal solely and directly with such Bank in connection
with the interest so assigned to an Assignee until (i) written notice of such
assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall have been given to the Company
and the Agent by such Bank and the Assignee; (ii) such Bank and its Assignee
shall have delivered to the Company and the Agent an Assignment and Acceptance
in the form of EXHIBIT I ("ASSIGNMENT AND ACCEPTANCE") together with any Note or
Notes subject to such assignment and (iii) the assignor Bank or Assignee has
paid to the Agent a processing fee in the amount of $3,500.

                  (b) From and after the date that the Agent notifies the
assignor Bank that it has received (and provided its consent with respect to) an
executed Assignment and Acceptance and payment of the above-referenced
processing fee, (i) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Bank under the Loan Documents, and (ii) the assignor Bank shall, to the extent
that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.

                  (c) Within five Business Days after its receipt of notice by
the Agent that it has received an executed Assignment and Acceptance and payment
of the processing fee, (and provided that it consents to such assignment in
accordance with SECTION 9.8(a)), the Company shall execute and deliver to the
Agent, new Notes evidencing such Assignee's assigned Loans and Commitment and,
if the assignor Bank has retained a portion of its Loans and its Commitment,
replacement Notes in the principal amount of the Loans retained by the assignor
Bank (such Notes to be in exchange for, but not in payment of, the Notes held by
such Bank). Immediately upon each Assignee's making its processing fee payment
under the Assignment and Acceptance, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect the addition
of the Assignee and the resulting adjustment of the Commitments arising
therefrom. The Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

                  (d) Any Bank may at any time sell to one or more commercial
banks or other Persons not Affiliates of the Company (a "PARTICIPANT")
participating interests in any Loans, the Commitment of that Bank and the other
interests of that Bank (the "ORIGINATOR") hereunder and under the other Loan
Documents;



                                       79

<PAGE>   85



PROVIDED, HOWEVER, that (i) the Originator's obligations under this Agreement
shall remain unchanged, (ii) the Originator shall remain solely responsible for
the performance of such obligations, (iii) the Company and the Agent shall
continue to deal solely and directly with the Originator in connection with the
Originator's rights and obligations under this Agreement and the other Loan
Documents, and (iv) no Bank shall transfer or grant any participating interest
under which the Participant has rights to approve any amendment to, or any
consent or waiver with respect to, this Agreement or any other Loan Document,
except to the extent such amendment, consent or waiver would require unanimous
consent of the Banks as described in the first proviso to SECTION 9.1. In the
case of any such participation, the Participant shall be entitled to the benefit
of SECTIONS 3.1, 3.3 and 9.5 as though it were also a Bank (as the case may be)
hereunder, and if amounts outstanding under this Agreement are due and unpaid,
or shall have been declared or shall have become due and payable upon the
occurrence of an Event of Default, each Participant shall be deemed to have the
right of set-off in respect of its participating interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing directly to it as a Bank under this Agreement.

                  (e) Notwithstanding any other provision in this Agreement, any
Bank may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement and the Notes held by
it in favor of any Federal Reserve Bank in accordance with Regulation A of the
FRB or U.S. Treasury Regulation 31 CAR ss.203.14, and such Federal Reserve Bank
may enforce such pledge or security interest in any manner permitted under
applicable law.

         9.9.     CONFIDENTIALITY. Each Bank agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as "confidential" or
"secret" by the Company and provided to it by the Company or any Subsidiary, or
by the Agent on such Company's or Subsidiary's behalf, under this Agreement or
any other Loan Document, and neither it nor any of its Affiliates shall use any
such information other than in connection with or in enforcement of this
Agreement and the other Loan Documents or in connection with other business now
or hereafter existing or contemplated with the Company or any Subsidiary; except
to the extent such information (i) was or becomes generally available to the
public other than as a result of disclosure by the Bank, or (ii) was or becomes
available on a non- confidential basis from a source other than the Company,
provided that such source is not bound by a confidentiality agreement with the
Company known to the Bank; PROVIDED, HOWEVER, that any Bank may disclose such
information (A) at the request or



                                       80

<PAGE>   86



pursuant to any requirement of any Governmental Authority to which the Bank is
subject or in connection with an examination of such Bank by any such authority;
(B) pursuant to subpoena or other court process; (C) subject to appropriate
confidentiality protections, when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) subject to appropriate
confidentiality protections, to the extent reasonably required in connection
with any litigation or proceeding to which the Agent, any Bank or its Affiliates
may be party; (E) to the extent reasonably required in connection with the
exercise of any remedy hereunder or under any other Loan Document; (F) to such
Bank's independent auditors and other professional advisors; (G) to any
Participant or Assignee, actual or potential, provided that such Person agrees
in writing to keep such information confidential to the same extent required of
the Banks hereunder; (H) as to any Bank or its Affiliate, as expressly permitted
under the terms of any other document or agreement regarding confidentiality to
which the Company or any Subsidiary is party or is deemed party with such Bank
or such Affiliate; and (I) to its Affiliates subject to confidentiality and only
for use in connection herewith.

         9.10.    SET-OFF. In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Borrowers, any such notice being waived by the Borrowers to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of the Borrowers against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Loan Document and although
such Obligations may be contingent or unmatured. Each Bank agrees promptly to
notify the Borrowers and the Agent after any such set-off and application made
by such Bank; PROVIDED, HOWEVER, that the failure to give such notice shall not
affect the validity of such set-off and application.

         9.11.    NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC. Each Bank
shall notify the Agent in writing of any changes in the address to which notices
to the Bank should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

         9.12.    COUNTERPARTS. This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken



                                       81

together shall be deemed to constitute but one and the same instrument.

         9.13.    SEVERABILITY. The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

         9.14.    NO THIRD PARTIES BENEFITED. This Agreement is made and entered
into for the sole protection and legal benefit of the Borrowers, the Banks, the
Agent and the Agent-Related Persons, and their permitted successors and assigns,
and no other Person shall be a direct or indirect legal beneficiary of, or have
any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

         9.15.    GOVERNING LAW AND JURISDICTION.

                  (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK WITHOUT REFERENCE
TO ITS CONFLICTS OF LAWS; PROVIDED THAT THE AGENT AND THE BANKS AND THE BORROWER
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

                  (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE
OF NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK, AND
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE BORROWERS, THE AGENT

NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE BORROWERS, THE AGENT AND
THE BANKS IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH
JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO. THE
BORROWERS, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS,
COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY
NEW YORK LAW.

         9.16. WAIVER OF JURY TRIAL. THE BORROWERS, THE BANKS AND THE AGENT EACH
WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN
DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION,
PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST
ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER

                                       82

<PAGE>   88



TORT CLAIMS, OR OTHERWISE. THE BORROWERS, THE BANKS AND THE AGENT EACH AGREE
THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A
JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR
RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO
ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART,
TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN
DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS.

Documents, embodies the entire agreement and understanding among the Borrowers,
the Banks and the Agent, and supersedes all prior or contemporaneous agreements
and understandings of such Persons, verbal or written, relating to the subject

                                    --------

         THIS GUARANTY (this "GUARANTY") dated as of September 25, 1998 is
executed by the undersigned (collectively hereinafter referred to as the
"GUARANTORS" and individually as a "GUARANTOR") in favor of Bank of America
National Trust and Savings Association, as Agent (as hereinafter defined in the
first recital below).

                                    RECITALS
                                    --------

         WHEREAS, HCR Manor Care, Inc. (the "COMPANY"), Manor Care, Inc. ("MANOR
CARE"), certain lenders (the "BANKS"), The Chase Manhattan Bank, as syndication
agent, TD Securities (USA) Inc., as documentation agent and Bank of America
National Trust and Savings Association, individually and as administrative agent
for the Banks (in such capacity, the "AGENT"), have entered into that certain
364 Day Credit Agreement dated as of even date herewith (as amended or modified
and in effect, hereinafter referred to as the "CREDIT AGREEMENT") pursuant to
which the Agent and the Banks may from time to time extend credit to the
Borrowers (each capitalized term used but not defined herein shall have the
meaning assigned thereto in the Credit Agreement);

         WHEREAS, as partial consideration for the Banks and the Agent entering
into the Credit Agreement, each of the undersigned agrees to execute and deliver
this Guaranty to the Agent for the benefit of the Agent and the Banks; and

         WHEREAS, the ability of the Borrowers to receive Credit Extensions from
time to time under the Credit Agreement is expected to be of benefit to the
consolidated group of which the Guarantors are a part,

         NOW, THEREFORE, in order to induce the Banks and the Agent to enter
into the Credit Agreement, each Guarantor hereby covenants as follows:

         SECTION 5. GUARANTY.

         a. Subject to SECTION 1(b), each Guarantor hereby jointly and severally
and unconditionally guarantees the performance and the full and prompt payment
when due, whether by acceleration or otherwise, and at all times thereafter, of
all Obligations of the Borrowers, including all such amounts which would become
due but for the operation of the automatic stay under Section 362(a) of the
United States Bankruptcy Code, 11 U.S.C. Section 362(a), and the operation of
Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C
Section 502(b) and Section 506(b)(all such



<PAGE>   100



Obligations being hereinafter collectively called the "GUARANTEED LIABILITIES").

         b. The liability of each of the Guarantors under this Guaranty shall
not exceed the maximum amount of liability that such Guarantor can hereby incur
without rendering this Guaranty void or voidable under Applicable Law relating
to fraudulent conveyance or fraudulent transfers, and not for any greater
amount. For purposes of determining such liability of each of the Guarantors,
due consideration shall be given to the direct and indirect benefits received by
each of the Guarantors as a result of the Credit Extension under the Credit
Agreement.

         c. Subject to clause (b) above, the liability under the Guaranty of
each Guarantor shall not be less than the outstanding amount of Loans which have
been advanced to such Guarantor as reflected from time to time in the statements
required by Section 6.1.1(g) of the Credit Agreement.

         d. This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect as to each
other Guarantor notwithstanding the dissolution of any Guarantor or that at any
time or from time to time all Guaranteed Liabilities may have been paid in full
so long as any Commitment under the Credit Agreement remains outstanding.

     SECTION 6. DISGORGED PAYMENTS. Each Guarantor further agrees that, if at
any time all or any part of any payment theretofore applied by the Agent or the
Banks to any of the Guaranteed Liabilities is or must be rescinded or returned
by the Agent or the Banks for any reason whatsoever (including the insolvency,
bankruptcy or reorganization of the Company or any Guarantor), such Guaranteed
Liabilities shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Agent or the Banks, and this
Guaranty shall continue to be effective or be reinstated, as the case may be, as
to such Guaranteed Liabilities, all as though such application by the Agent or
the Banks had not been made.

         SECTION 7. COVENANTS. Each Guarantor agrees with the Agent and each
Bank that, until all Commitments have been terminated and all Obligations have
been paid and performed in full, each Guarantor will perform all Obligations
applicable to such Guarantor set forth in Article VI of the Credit Agreement.

         SECTION 8. CERTAIN PERMITTED ACTIONS. To the extent permitted by law or
the Loan Documents, each of the Agent and any Bank may, from time to time,
whether before or after any discontinuance of this Guaranty, at its sole
discretion and



<PAGE>   101



without notice to any Guarantor, take any or all of the following actions
without impairing its rights arising hereunder: (a) retain or obtain a lien upon
or a security interest in any property to secure any of the Guaranteed
Liabilities, (b) retain or obtain the primary or secondary obligation of any
obligor or obligors, in addition to such Guarantors' obligations, with respect
to any of the Guaranteed Liabilities, (c) extend or renew for one or more
periods (whether or not longer than the original period), alter or exchange any
of the Guaranteed Liabilities, or release or compromise any obligation of any
Obligor under any Loan Document or any obligation of any nature of any other
obligor with respect to any of the Guaranteed Liabilities, (d) release or fail
to perfect its lien upon or security interest in, or impair, surrender, release
or permit any substitution or exchange for, all or any part of any property
securing any of the Guaranteed Liabilities, or extend or renew for one or more
periods (whether or not longer than the original period) or release, compromise,
alter or exchange any obligations of any nature of any obligor with respect to
any such property, and (e) resort to any Guarantor for payment of any of the
Guaranteed Liabilities, whether or not the Agent or the Banks (i) shall have
resorted to any property securing any of the Guaranteed Liabilities or (ii)
shall have proceeded against any other obligor primarily or secondarily
obligated with respect to any of the Guaranteed Liabilities (all of the actions
referred to in preceding CLAUSES (i) and (ii) being hereby expressly waived by
each Guarantor to the fullest extent permitted by Applicable Law).

         SECTION 9. APPLICATION OF FUNDS. The Agent may apply any payments
hereunder to the payment of expenses which the Agent incurs in connection with
the enforcement of this Guaranty, including reasonable attorneys' fees and legal
expenses. The Agent may apply any balance of such payments hereunder toward the
payment of such of the Guaranteed Liabilities, and in such order of application,
as the Agent may, in its sole discretion, elect from time to time.

         SECTION 10. LIMIT ON SUBROGATION; WAIVERS.

         a. Except as provided in clause (b) below, no payment made by or for
the account of any Guarantor pursuant to this Guaranty shall entitle any
Guarantor by subrogation or otherwise to any payment by any Borrower or from or
out of any property of any Borrower, and no Guarantor shall exercise any right
or remedy against any Borrower or any property of any Borrower by reason of any
performance by such Guarantor of this Guaranty, all of which rights and remedies
are hereby waived by such Guarantor to the fullest extent permitted by
Applicable Law.




<PAGE>   102



         b. In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, INTER SE, that in the event any payment or
distribution is made by any Guarantor (a "FUNDING GUARANTOR") under this
Guaranty, such Funding Guarantor shall be entitled to a contribution from all
other Guarantors in a PRO RATA amount based on the Adjusted Net Assets (as
hereinafter defined) of each Guarantor (including the Funding Guarantor) for all
payments, damages and expenses incurred by that Funding Guarantor in discharging
the Guaranteed Liabilities or any other Guarantor's obligations with respect to
this Guaranty. "ADJUSTED NET ASSETS" of any Guarantor at any date means the
lesser of (a) the amount by which the fair value of the property of such
Guarantor exceeds the total amount of liabilities (including, without
limitation, contingent liabilities, but excluding liabilities of such Guarantor
under this Guaranty) of such Guarantor at such date, and (b) the amount by which
the present fair salable value of the assets of such Guarantor at such date
exceeds the amount that will be required to pay the probable liability of such
Guarantor on its debts (after giving effect to all contingent liabilities, but
excluding liabilities of such Guarantor under this Guaranty) as they become
absolute and matured.

         c. To the extent permitted by Applicable Law, each Guarantor hereby
expressly waives (i) notice of the acceptance by the Agent or the Banks of this
Guaranty, (ii) notice of the existence or creation or non-payment of all or any
of the Guaranteed Liabilities, (iii) presentment, demand, notice of dishonor,
protest, and all other notices whatsoever, (iv) all diligence in collection or
protection of or realization upon the Guaranteed Liabilities or any security for
or guaranty of any of the foregoing and (v) all other rights and defenses
(including, without limitation, all suretyship rights and defenses) the
assertion of which would in any way diminish the liability of such Guarantor
hereunder.

         SECTION 11. TRANSFER OF OBLIGATIONS. Subject to Section 9.8 of the
Credit Agreement, the Agent and the Banks may, from time to time, without notice
to any Guarantor, assign or transfer, or cause to be assigned or transferred,
any or all of the Guaranteed Liabilities or any interest therein and,
notwithstanding any such assignment or transfer or any subsequent assignment or
transfer thereof, such Guaranteed Liabilities shall be and remain Guaranteed
Liabilities for the purposes of this Guaranty, and each and every immediate and
successive assignee or transferee of any of the Guaranteed Liabilities or of any
interest therein shall, to the extent of the interest of such assignee or
transferee in the Guaranteed Liabilities, be entitled to the benefits of this
Guaranty to the same extent as if such assignee or transferee were the Agent or
a Bank.

         SECTION 12. NO CONDITIONS TO EFFECTIVENESS. No claim or defense by any
Person as to the invalidity or unenforceability of any obligation under the Loan
Documents shall affect or impair the obligations of the Guarantors under this
Guaranty. The obligations of the Guarantors under this Guaranty shall be
absolute and unconditional irrespective of any circumstance whatsoever which
might constitute a legal or equitable discharge or defense of any Borrower. Each
Guarantor hereby acknowledges that there are no conditions to the effectiveness
of this Guaranty.

         SECTION 13. WARRANTIES. Each Guarantor hereby warrants and represents
to the Agent and the Banks that (i) it now has and expects to continue to have
independent means of obtaining information concerning the affairs, financial
condition and business of the Company, and the Agent and the Banks shall not
have any duty or responsibility to provide such Guarantor with any credit or
other information concerning the affairs, financial condition or business of the
Company which may come into such Person's possession; (ii) the execution,
delivery and performance of this Guaranty by such Guarantor are within its
corporate or partnership powers and do not (a) contravene any law, rule or
regulation presently in effect which affects or binds it or any of its
properties, or (b) conflict with or result in a material breach of any guaranty
or loan or credit agreement or any other agreement or instrument to which it is
a party in respect of indebtedness for money borrowed; and (iii) any and all
information heretofore or hereafter provided by such Guarantor to the Agent and
the Banks hereunder and certified by a Responsible Officer of such Guarantor is
and shall be true and accurate in all material respects as of the date
furnished.

         SECTION 14. MODIFICATION OF GUARANTY. This Guaranty shall not be
amended, supplemented or otherwise modified without the written consent of the
Agent and the Majority Banks and, as to any Guarantor, such Guarantor. Except as
otherwise provided in the Credit Agreement, this Guaranty shall not be released
or terminated as to any Guarantor without the written consent of all Banks.

         SECTION 15. NOTICES.

                                    GUARANTY
                                    --------

         THIS GUARANTY (this "GUARANTY") dated as of ____________, 1998 is
executed by the undersigned (collectively hereinafter referred to as the
"GUARANTORS" and individually as a "GUARANTOR") in favor of Bank of America
National Trust and Savings Association, as Agent (as hereinafter defined in the
first recital below).

                                    RECITALS

         WHEREAS, HCR Manor Care, Inc. (the "COMPANY"), Manor Care, Inc. ("MANOR
CARE"), certain lenders (the "BANKS"), The Chase Manhattan Bank, as syndication
agent, TD Securities (USA) Inc., as documentation agent and Bank of America
National Trust and Savings Association, individually and as administrative agent
for the Banks (in such capacity, the "AGENT"), have entered into that certain
364 Day Credit Agreement dated as of September 25, 1998 (as amended or modified
and in effect, hereinafter referred to as the "CREDIT AGREEMENT") pursuant to
which the Agent and the Banks may from time to time extend credit to the
Borrowers (each capitalized term used but not defined herein shall have the
meaning assigned thereto in the Credit Agreement);

         WHEREAS, as partial consideration for the Banks and the Agent entering
into the Credit Agreement, each of the undersigned agreed to execute and deliver
this Guaranty to the Agent for the benefit of the Agent and the Banks; and

         WHEREAS, the ability of the Borrowers to receive Credit Extensions from
time to time under the Credit Agreement is expected to be of benefit to the
consolidated group of which the Guarantors are a part,

         NOW, THEREFORE, in order to induce the Banks and the Agent to enter
into the Credit Agreement, each Guarantor hereby covenants as follows:

         SECTION 20.            GUARANTY.

         a. Subject to SECTION 1(b), each Guarantor hereby jointly and severally
and unconditionally guarantees the performance and the full and prompt payment
when due, whether by acceleration or otherwise, and at all times thereafter, of
all Obligations of Manor Care under the Credit Agreement and the Notes,
including all such amounts which would become due but for the operation of the
automatic stay under Section 362(a) of the United States Bankruptcy Code, 11
U.S.C. Section 362(a), and the operation of Sections 502(b) and 506(b) of the
United States Bankruptcy Code, 11 U.S.C



<PAGE>   123



ss.502(b) and ss.506(b)(all such Obligations being hereinafter collectively
called the "GUARANTEED LIABILITIES").

         b. The liability of each of the Guarantors under this Guaranty shall
not exceed the maximum amount of liability that such Guarantor can hereby incur
without rendering this Guaranty void or voidable under Applicable Law relating
to fraudulent conveyance or fraudulent transfers, and not for any greater
amount. For purposes of determining such liability of each of the Guarantors,
due consideration shall be given to the direct and indirect benefits received by
each of the Guarantors as a result of the Credit Extension under the Credit
Agreement.

         c. Subject to clause (b) above, the liability under the Guaranty of
each Guarantor shall not be less than the outstanding amount of Loans which have
been advanced to such Guarantor as reflected from time to time in the statements
required by Section 6.1.1(g) of the Credit Agreement.

         d. This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect as to each
other Guarantor notwithstanding the dissolution of any Guarantor or that at any
time or from time to time all Guaranteed Liabilities may have been paid in full
so long as any Commitment under the Credit Agreement remains outstanding.

     SECTION 21. DISGORGED PAYMENTS. Each Guarantor further agrees that, if at
any time all or any part of any payment theretofore applied by the Agent or the
Banks to any of the Guaranteed Liabilities is or must be rescinded or returned
by the Agent or the Banks for any reason whatsoever (including the insolvency,
bankruptcy or reorganization of Manor Care or any Guarantor), such Guaranteed
Liabilities shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Agent or the Banks, and this
Guaranty shall continue to be effective or be reinstated, as the case may be, as
to such Guaranteed Liabilities, all as though such application by the Agent or
the Banks had not been made.

         SECTION 22. COVENANTS. Each Guarantor agrees with the Agent and each
Bank that, until all Commitments have been terminated and all Obligations have
been paid and performed in full, each Guarantor will perform all Obligations
applicable to such Guarantor set forth in Article VI of the Credit Agreement.

     SECTION 23. CERTAIN PERMITTED ACTIONS.  To the extent permitted by law or 
the Loan Documents, each of the Agent and any Bank may, from time to time,
whether before or after any discontinuance of this Guaranty, at its sole
discretion and



<PAGE>   124



without notice to any Guarantor, take any or all of the following actions
without impairing its rights arising hereunder: (a) retain or obtain a lien upon
or a security interest in any property to secure any of the Guaranteed
Liabilities, (b) retain or obtain the primary or secondary obligation of any
obligor or obligors, in addition to such Guarantors' obligations, with respect
to any of the Guaranteed Liabilities, (c) extend or renew for one or more
periods (whether or not longer than the original period), alter or exchange any
of the Guaranteed Liabilities, or release or compromise any obligation of any
Obligor under any Loan Document or any obligation of any nature of any other
obligor with respect to any of the Guaranteed Liabilities, (d) release or fail
to perfect its lien upon or security interest in, or impair, surrender, release
or permit any substitution or exchange for, all or any part of any property
securing any of the Guaranteed Liabilities, or extend or renew for one or more
periods (whether or not longer than the original period) or release, compromise,
alter or exchange any obligations of any nature of any obligor with respect to
any such property, and (e) resort to any Guarantor for payment of any of the
Guaranteed Liabilities, whether or not the Agent or the Banks (i) shall have
resorted to any property securing any of the Guaranteed Liabilities or (ii)
shall have proceeded against any other obligor primarily or secondarily
obligated with respect to any of the Guaranteed Liabilities (all of the actions
referred to in preceding CLAUSES (i) and (ii) being hereby expressly waived by
each Guarantor to the fullest extent permitted by Applicable Law).

         SECTION 24. APPLICATION OF FUNDS. The Agent may apply any payments
hereunder to the payment of expenses which the Agent incurs in connection with
the enforcement of this Guaranty, including reasonable attorneys' fees and legal
expenses. The Agent may apply any balance of such payments hereunder toward the
payment of such of the Guaranteed Liabilities, and in such order of application,
as the Agent may, in its sole discretion, elect from time to time.

         SECTION 25. LIMIT ON SUBROGATION; WAIVERS.

         a. Except as provided in clause (b) below, no payment made by or for
the account of any Guarantor pursuant to this Guaranty shall entitle any
Guarantor by subrogation or otherwise to any payment by Manor Care or from or
out of any property of Manor Care, and no Guarantor shall exercise any right or
remedy against Manor Care or any property of Manor Care by reason of any
performance by such Guarantor of this Guaranty, all of which rights and remedies
are hereby waived by such Guarantor to the fullest extent permitted by
Applicable Law.




<PAGE>   125



         b. In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, INTER SE, that in the event any payment or
distribution is made by any Guarantor (a "FUNDING GUARANTOR") under this
Guaranty, such Funding Guarantor shall be entitled to a contribution from all
other Guarantors in a PRO RATA amount based on the Adjusted Net Assets (as
hereinafter defined) of each Guarantor (including the Funding Guarantor) for all
payments, damages and expenses incurred by that Funding Guarantor in discharging
the Guaranteed Liabilities or any other Guarantor's obligations with respect to
this Guaranty. "ADJUSTED NET ASSETS" of any Guarantor at any date means the
lesser of (a) the amount by which the fair value of the property of such
Guarantor exceeds the total amount of liabilities (including, without
limitation, contingent liabilities, but excluding liabilities of such Guarantor
under this Guaranty) of such Guarantor at such date, and (b) the amount by which
the present fair salable value of the assets of such Guarantor at such date
exceeds the amount that will be required to pay the probable liability of such
Guarantor on its debts (after giving effect to all contingent liabilities, but
excluding liabilities of such Guarantor under this Guaranty) as they become
absolute and matured.

         c. To the extent permitted by Applicable Law, each Guarantor hereby
expressly waives (i) notice of the acceptance by the Agent or the Banks of this
Guaranty, (ii) notice of the existence or creation or non-payment of all or any
of the Guaranteed Liabilities, (iii) presentment, demand, notice of dishonor,
protest, and all other notices whatsoever, (iv) all diligence in collection or

                                    --------

         WHEREAS, the Guarantor, Manor Care, Inc. ("MANOR CARE"), certain
lenders (the "BANKS"), The Chase Manhattan Bank, as syndication agent, TD

         WHEREAS, as partial consideration for the Banks and the Agent entering
into the Credit Agreement, the undersigned agrees to execute and deliver this
Guaranty to the Agent for the benefit of the Agent and the Banks; and

         WHEREAS, the ability of Manor Care to receive Credit Extensions from
time to time under the Credit Agreement is expected to be of benefit to the

         a. Subject to SECTION 1(b), the Guarantor hereby unconditionally
guarantees the performance and the full and prompt payment when due, whether by
acceleration or otherwise, and at all times thereafter, of all Obligations of
Manor Care, including all such amounts which would become due but for the
operation of the automatic stay under Section 362(a) of the United States

shall be given to the direct and indirect benefits received by the Guarantor as
a result of the Credit Extensions under the Credit Agreement.

         c. This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect as to the

time or from time to time all Guaranteed Liabilities may have been paid in full

     SECTION 36. DISGORGED PAYMENTS. The Guarantor further agrees that, if at
any time all or any part of any payment theretofore applied by the Agent or the
Banks to any of the Guaranteed Liabilities is or must be rescinded or returned
by the Agent or the Banks for any reason whatsoever (including the insolvency,
bankruptcy or reorganization of Manor Care or the Guarantor), such Guaranteed
Liabilities shall, for the purposes of this Guaranty, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Agent or the Banks, and this
Guaranty shall continue to be effective or be reinstated, as the case may be, as
to such Guaranteed Liabilities, all as though such application by the Agent or
the Banks had not been made.

for one or more periods (whether or not longer than the original period) or
release, compromise, alter or exchange any obligations of any nature of any
obligor with respect to any such property, and (e) resort to the Guarantor for
payment of any of the Guaranteed Liabilities, whether or not the Agent or the

Liabilities or (ii) shall have proceeded against any other obligor primarily or
secondarily obligated with respect to any of the Guaranteed Liabilities (all of
the actions referred to in preceding CLAUSES (i) and (ii) being hereby expressly
waived by the Guarantor to the fullest extent permitted by Applicable Law).

         SECTION 39. APPLICATION OF FUNDS. The Agent may apply any payments
hereunder to the payment of expenses which the Agent incurs in connection with
the enforcement of this Guaranty, including reasonable attorneys' fees and legal
expenses. The Agent may apply any balance of such payments hereunder toward the
payment of such of the Guaranteed Liabilities, and in such order of application,
as the Agent may, in its sole discretion, elect from time to time.

         SECTION 40. LIMIT ON SUBROGATION; WAIVERS.

         a. No payment made by or for the account of the Guarantor pursuant to
this Guaranty shall entitle the Guarantor by subrogation or otherwise to any
payment by Manor Care or from or out of any property of Manor Care, and the
Guarantor shall not exercise any right or remedy against any Borrower or any
property of Manor Care by reason of any performance by the Guarantor of this
Guaranty, all of which rights and remedies are hereby waived by the Guarantor to
the fullest extent permitted by Applicable Law.

expressly waives (i) notice of the acceptance by the Agent or the Banks of this
Guaranty, (ii) notice of the existence or creation or non-payment of all or any
of the Guaranteed Liabilities, (iii) presentment, demand, notice of dishonor,
protest, and all other notices whatsoever, (iv) all diligence in collection or
protection of or realization upon the Guaranteed Liabilities or any security for
