Loan shall not limit or otherwise affect the obligations of the Borrowers

Borrowing, in the case of an Absolute Rate Auction; provided that Competitive
Bids submitted by the Agent (or any Affiliate of the Agent) in the capacity of a
Bank or Designated Bidder may be submitted, and may only be submitted, if the
Agent or such Affiliate notifies the applicable Borrower of the terms of the
offer or offers contained therein not later than (A) 6:15 a.m. (San Francisco
time) three Business Days prior to the proposed date of Borrowing, in the case
of a LIBOR Auction or (B) 6:15 a.m. (San Francisco time) on the proposed date of
Borrowing, in the case of an Absolute Rate Auction.

                  (ii) Each Competitive Bid shall be in substantially the form
of EXHIBIT H, specifying therein:

                  (A) the proposed date of Borrowing;




                                       35

<PAGE>   41



                  (B) the principal amount of each Bid Loan for which such
         Competitive Bid is being made, which principal amount (x) may be equal
         to, greater than or less than the Commitment of the quoting Bank, (y)
         must be $5,000,000 or in multiples of $1,000,000 in excess thereof, and
         (z) may not exceed the principal amount of Bid Loans for which
         Competitive Bids were requested;

                  (C) in case a Borrower elects a LIBOR Auction, the margin
         above or below the LIBO Rate (the "LIBOR BID MARGIN") offered for each
         such Bid Loan, expressed in multiples of 1/1000th of one basis point to
         be added to or subtracted from the applicable LIBO Rate and the
         Interest Period applicable thereto;

                  (D) in case a Borrower elects an Absolute Rate Auction, the
         rate of interest per annum expressed in multiples of 1/1000th of one
         basis point (the "ABSOLUTE RATE") offered for each such Bid Loan; and

                  (E) the identity of the quoting Bank or Designated Bidder.

A Competitive Bid may contain up to three separate offers by the quoting Bank or
Designated Bidder with respect to each Interest Period specified in the related
Invitation for Competitive Bids.

                  (iii) Any Competitive Bid shall be disregarded if it:

                  (A) is not substantially in conformity with EXHIBIT H or does
         not specify all of the information required by SECTION (c)(ii) of this
         Section;

                  (B) contains qualifying, conditional or similar language;

                  (C) proposes terms other than or in addition to those set
         forth in the applicable Invitation for Competitive Bids; or

                  (D) arrives after the time set forth in SECTION (C)(I).

                  (d) Promptly on receipt and not later than 7:00 a.m. (San
Francisco time) three Business Days prior to the proposed date of Borrowing in
the case of a LIBOR Auction, or 7:00 a.m. (San Francisco time) on the proposed
date of Borrowing, in the case of an Absolute Rate Auction, the Agent will
notify the applicable Borrower of the terms (i) of any Competitive Bid submitted
by a Bank or Designated Bidder that is in accordance with SECTION 2.6(c), and
(ii) of any Competitive Bid that amends,



                                       36

<PAGE>   42



modifies or is otherwise inconsistent with a previous Competitive Bid submitted
by such Bank or Designated Bidder with respect to the same Competitive Bid
Request. Any such subsequent Competitive Bid shall be disregarded by the Agent
unless such subsequent Competitive Bid is submitted solely to correct a manifest
error in such former Competitive Bid and only if received within the times set
forth in SECTION 2.6(c). The Agent's notice to the applicable Borrower shall
specify (1) the aggregate principal amount of Bid Loans for which offers have
been received for each Interest Period specified in the related Competitive Bid
Request; and (2) the respective principal amounts and LIBOR Bid Margins or
Absolute Rates, as the case may be, so offered. Subject only to the provisions
of SECTIONS 4.2, 4.5 and 5.2 hereof and the provisions of this subsection (d),
any Competitive Bid shall be irrevocable except with the written consent of the
Agent given on the written instructions of the applicable Borrower.

                  (e) Not later than 7:30 a.m. (San Francisco time) three
Business Days prior to the proposed date of Borrowing, in the case of a LIBOR
Auction, or 7:30 a.m. (San Francisco time) on the proposed date of Borrowing, in
the case of an Absolute Rate Auction, the applicable Borrower shall notify the
Agent of its acceptance or non-acceptance of the offers so notified to it
pursuant to SECTION 2.6(d). Such Borrower shall be under no obligation to accept
any offer and may choose to reject all offers. In the case of acceptance, such
notice shall specify the aggregate principal amount of offers for each Interest
Period that is accepted. Such Borrower may accept any Competitive Bid in whole
or in part; provided that:

                  (i) the aggregate principal amount of each Bid Borrowing may
         not exceed the applicable amount set forth in the related Competitive
         Bid Request;

                  (ii) the principal amount of each Bid Borrowing must be
         $5,000,000 or in any multiple of $1,000,000 in excess thereof;

                  (iii) acceptance of offers may only be made on the basis of
         ascending LIBOR Bid Margins or Absolute Rates within each Interest
         Period, as the case may be; and

                  (iv) such Borrower may not accept any offer that is described
         in SECTION 2.6(c)(iii) or that otherwise fails to comply with the
         requirements of this Agreement.

                  (f) If offers are made by two or more Banks or Designated
Bidders with the same LIBOR Bid Margins or Absolute



                                       37

<PAGE>   43



Rates, as the case may be, for a greater aggregate principal amount than the
amount in respect of which such offers are accepted for the related Interest
Period, the principal amount of Bid Loans in respect of which such offers are
accepted shall be allocated by the Agent among such Banks or Designated Bidders
as nearly as possible (in such multiples, not less than $1,000,000, as the Agent
may deem appropriate) in proportion to the aggregate principal amounts of such
offers. Determination by the Agent of the amounts of Bid Loans shall be
conclusive in the absence of manifest error.

                  (g) (i) The Agent will promptly notify each Bank or Designated
Bidder having submitted a Competitive Bid if its offer has been accepted and, if
its offer has been accepted, of the amount of the Bid Loan or Bid Loans to be
made by it on the date of the Bid Borrowing.

                  (ii) Each Bank or Designated Bidder, which has received notice
         pursuant to SECTION 2.6(g)(i) that its Competitive Bid has been
         accepted, shall make the amounts of such Bid Loans 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) in the case of Absolute Rate
         Bid Loans, and by 11:00 a.m. (San Francisco time) in the case of LIBOR
         Bid Loans, on such date of Bid Borrowing, in funds immediately
         available to the Agent for the account of such Borrower at the Agent's
         Payment Office. Promptly thereafter the proceeds of such Bid Borrowing
         shall then be made available to the applicable Borrower by wire
         transfer in accordance with such Borrower's instructions.

                  (iii) Promptly following each Bid Borrowing, the Agent shall
         notify each Bank and Designated Bidder of the ranges of bids submitted
         and the highest and lowest Bids accepted for each Interest Period
         requested by such Borrower and the aggregate amount borrowed pursuant
         to such Bid Borrowing.

                  (iv) From time to time, the Borrowers and the Banks and
         Designated Bidders shall furnish such information to the Agent as the
         Agent may request relating to the making of Bid Loans, including the
         amounts, interest rates, dates of borrowings and maturities thereof,
         for purposes of the allocation of amounts received from the Borrowers
         for payment of all amounts owing hereunder.

                  (h) If, on or prior to the proposed date of Borrowing, the
Commitments have not been terminated and if, on such proposed date of Borrowing
all applicable conditions to funding referenced



                                       38

<PAGE>   44



in SECTIONS 4.2, 4.5 and 5.2 hereof are satisfied, the Banks and Designated
Bidders whose offers a Borrower has accepted will fund each Bid Loan so
accepted. Nothing in this SECTION 2.6 shall be construed as a right of first
offer in favor of the Banks or Designated Bidders or to otherwise limit the
ability of the Borrowers to request and accept credit facilities from any Person
(including any of the Banks or Designated Bidders).

         2.7.     SWINGLINE.

                  (a) The Swingline Bank shall from time to time from the
Effective Date through the day prior to the Revolving Termination Date make
Swingline Loans to the Borrowers in such amounts as the Borrowers may request,
PROVIDED that (i) after giving effect to such Swingline Loan, the Swingline
Outstandings shall not exceed $20,000,000, (ii) after giving effect to such
Swingline Loan, the aggregate principal amount of all outstanding Loans plus the
Effective Amount of all L/C Obligations shall not exceed the combined
Commitments, and (iii) without the consent of all of the Banks, no Swingline
Loan may be made during the continuation of any Default or Event of Default. The
Borrowers may borrow, repay and reborrow under this Section. Unless notified to
the contrary by the Swingline Bank, borrowings under the Swingline may be made
in amounts which are integral multiples of $100,000 upon telephonic request by a
Responsible Officer of a Borrower made to the Agent not later than 10:00 a.m.,
San Francisco time, on the Business Day of the requested Swingline Loan (which
telephonic request shall be promptly confirmed in writing by telecopier).
Promptly after receipt of such a request for a Swingline Loan, the Agent shall
provide telephonic verification to the Swingline Bank that, after giving effect
to such request, the aggregate principal amount of all outstanding Loans plus
the Effective Amount of all L/C Obligations shall not exceed the combined
Commitments (and such verification shall be promptly confirmed in writing by
telecopier). Promptly thereafter the proceeds of such Swingline Loan shall then
be made available to the applicable Borrower by the Swingline Lender by wire
transfer in accordance with such Borrower's instructions. Unless the Swingline
Bank otherwise agrees, each repayment of a Swingline Loan shall be in an amount
which is an integral multiple of $100,000. If a Borrower instructs the Swingline
Bank to debit its demand deposit account at the Swingline Bank in the amount of
any payment with respect to Swingline Loan, or the Swingline Bank otherwise
receives repayment, after 3:00 p.m., San Francisco time, on a Business Day, such
payment shall be deemed received on the next Business Day. The Swingline Bank
shall promptly notify the Agent of the Swingline Loan Outstandings each time
there is a change therein.

                  (b) Swingline Loans shall bear interest at a fluctuating rate
per annum equal to the Base Rate. Interest



                                       39

<PAGE>   45



shall be payable quarterly on the last Business Day of each calendar quarter and
in any event on the Revolving Termination Date. The Swingline Bank shall be
responsible for submitting invoices to the Borrowers for such interest. The
interest payable on Swingline Loans shall be solely for the account of the
Swingline Bank unless and until the Banks fund their participations therein
pursuant to clause (d) of this Section.

                  (c) The Swingline Loans shall be payable on demand made by the
Swingline Bank and in any event on the Revolving Termination Date.

                  (d) Upon the making of a Swingline Loan, each Bank shall be
deemed to have purchased from the Swingline Bank a participation therein in an
amount equal to that Bank's Pro Rata Share TIMES the amount of the Swingline
Loan. Upon demand made by the Swingline Bank, each Bank shall, according to its
Pro Rata Share, promptly provide to the Swingline Bank its purchase price
therefor in an amount equal to its participation therein. The obligation of each
Bank to so provide its purchase price to the Swingline Bank shall be absolute
and unconditional (except only demand made by the Swingline Bank) and shall not
be affected by the occurrence of a Default or Event of Default; PROVIDED that no
Bank shall be obligated to purchase its Pro Rata Share of (i) Swingline Loans to
the extent that Swingline Outstandings are in excess of $20,000,000 and (ii) any
Swingline Loan made (absent the consent of all of the Banks) when the Swingline
Bank has written notice that a Default or Event of Default has occurred and such
Default or Event of Default remains continuing. Each Bank that has provided to
the Swingline Bank the purchase price due for its participation in Swingline
Loans shall thereupon acquire a pro rata participation, to the extent of such
payment, in the claim of the Swingline Bank against the applicable Borrower for
principal and interest and shall share, in accordance with that pro rata
participation, in any principal payment made by such Borrower with respect to
such claim and in any interest payment made by such Borrower (but only with
respect to periods subsequent to the date such Bank paid the Swingline Bank its
purchase price) with respect to such claim.

                  (e) Upon any demand for payment of the Swingline Outstandings
by the Swingline Bank (unless the applicable Borrower has made other
arrangements acceptable to the Swingline Bank to repay in full all Swingline
Outstandings), such Borrower shall request a Committed Loan in an amount
sufficient to repay Swingline Outstandings. In each case, the Agent shall
automatically provide the Committed Loans made by each Bank to the Swingline
Bank (which the Swingline Bank shall then apply to the Swingline Outstandings).
In the event that the applicable Borrower fails to request a Committed Loan
within the time specified by SECTION 2.3 on any such date, the Agent may, but



                                       40

<PAGE>   46



shall not be required to, without notice to or the consent of such Borrower,
cause Committed Loans to be made by the Banks under the Commitment in amounts
which are sufficient to reduce the Swingline Outstandings as required above. The
conditions precedent set forth in ARTICLE V shall not apply to Committed Loans
to be made by the Banks pursuant to the three preceding sentences. The proceeds
of such Committed Loans shall be paid directly to the Swingline Bank for
application to the Swingline Outstandings.

         2.8.     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, (a) the then-outstanding principal
amount of the Loans plus the Effective Amount of all L/C Obligations would
exceed the amount of the combined Commitments then in effect or (b) the
Effective Amount of all L/C Obligations then outstanding would exceed the L/C
Commitment. 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. If and to the extent specified by the Borrowers
in the notice to the Agent, some or all of the reduction in the combined
Commitments shall be applied to reduce the L/C Commitment.

         2.9.     OPTIONAL AND MANDATORY PREPAYMENTS; MANDATORY COMMITMENT 
REDUCTIONS.

                  (a) Subject to SECTION 4.4, 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 4.4.

                  (b) Bid Loans may not be voluntarily prepaid unless consented
to by the applicable Bank or Designated Bidder.




                                       41

<PAGE>   47



                  (c) If on any date the Effective Amount of L/C Obligations
exceeds the L/C Commitment, the Borrowers shall Cash Collateralize on such date
the outstanding Letters of Credit in an amount equal to the excess of the
maximum amount then available to be drawn under the Letters of Credit over the
L/C Commitment. Subject to SECTION 4.4, if on any date the aggregate principal
amount of all Loans then outstanding plus the Effective Amount of all L/C
Obligations and minus the face amount of the Letters of Credit that have been
Cash Collateralized exceeds the combined Commitments, the Borrowers shall
immediately, and without notice or demand, prepay the outstanding principal
amount of the Loans and L/C Advances by an amount equal to the applicable
excess.

         2.10.    REPAYMENT.

                  (a) REVOLVING LOANS. The Borrowers shall repay to the Banks on
the Revolving Termination Date the aggregate principal amount of Revolving Loans
outstanding on such date.

                  (b) BID LOANS. The Borrowers shall repay each Bid Loan on the
last day of the relevant Interest Period.

         2.11.    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. Each Bid Loan shall bear interest on the outstanding
principal amount thereof from the relevant Borrowing Date at a rate per annum
equal to the LIBO Rate plus (or minus) the LIBOR Bid Margin, or at the Absolute
Rate, as the case may be.

                  (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 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



                                       42

<PAGE>   48



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%.

                  (d) Anything herein to the contrary notwithstanding, the
obligations of the Borrowers to any Bank or Designated Bidder hereunder shall be
subject to the limitation that payments of interest shall not be required for
any period for which interest is computed hereunder, to the extent (but only to
the extent) that contracting for or receiving such payment by such Bank or
Designated Bidder would be contrary to the provisions of any law applicable to
such Bank or Designated Bidder limiting the highest rate of interest that may be
lawfully contracted for, charged or received by such Bank or Designated Bidder,
and in such event the Borrowers shall pay such Bank or Designated Bidder
interest at the highest rate permitted by applicable law.

         2.12.    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 V 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 364 Day 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 364 Day 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



                                       43

<PAGE>   49



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. The aggregate
outstanding principal amount of Bid Loans shall not be included in any
calculation of the aggregate utilization of this Agreement; HOWEVER, all other
Loans and all L/C Obligations shall be so included.

         2.13.    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, the Banks and Designated Bidders in
the absence of manifest or demonstrable error. The Agent will, at the request of
the Borrowers or any Bank or Designated Bidder, deliver to the Borrowers or the
Bank or Designated Bidder, as the case may be, a statement showing the
quotations used by the Agent in determining any interest rate.

         2.14.    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 and Designated Bidders 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 (or Designated Bidder) 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



                                       44

<PAGE>   50



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

         2.15.    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



                                       45

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.

         2.16.    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 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, but subject to SECTION 10.9) 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. Any Bank having outstanding
both Committed Loans and Bid Loans at any time a right of set-off is exercised
by such Bank and applying such setoff to the Loans shall apply the proceeds of
such set-off first to such Bank's Committed Loans, until its Committed Loans are
reduced to zero, and thereafter to its Bid Loans.

                                   ARTICLE III

                              THE LETTERS OF CREDIT

         3.1.     THE LETTER OF CREDIT SUBFACILITY.

                  (a) On the terms and conditions set forth herein (i) the
Issuing Bank agrees, (A) from time to time on any Business Day during the period
from the Effective Date to the Revolving Termination Date to issue Letters of
Credit for the account of the Borrowers and their Subsidiaries, and to amend or
renew Letters of Credit previously issued by it, in accordance with SECTIONS
3.2(c) and 3.2(d), and (b) to honor drafts under the Letters of Credit; and (ii)
the Banks severally agree to participate in Letters of Credit Issued for the
account of the Borrowers and their Subsidiaries; PROVIDED, that the Issuing Bank
shall not be obligated to Issue, and no Bank shall be obligated to participate
in, any Letter of Credit if as of the date of Issuance of such Letter of Credit
(the "ISSUANCE DATE") (1) the Effective Amount of all L/C Obligations plus the
outstanding principal amount of all Loans exceeds the combined Commitments, (2)
the participation of any Bank in the Effective Amount of all L/C Obligations
plus the outstanding principal amount of the Revolving Loans of such Bank plus
the participation of such Bank in the outstanding principal amount of Swingline
Loans exceeds such Bank's Commitment, or (3) the Effective Amount of L/C
Obligations exceeds the L/C Commitment. Within the foregoing limits, and subject
to the other terms and conditions hereof, the Borrowers' ability to obtain
Letters of Credit shall be fully revolving, and, accordingly, the Borrowers may,
during the foregoing period, obtain Letters of Credit to replace Letters of
Credit which have expired or which have been drawn upon and reimbursed.

                  (b) The Issuing Bank is under no obligation to Issue any
Letter of Credit if:

                  (i) any order, judgment or decree of any Governmental
         Authority or arbitrator shall by its terms purport to enjoin or
         restrain the Issuing Bank from Issuing such Letter of Credit, or any
         Requirement of Law applicable to the Issuing Bank or any request or
         directive (whether or not having the force of law) from any
         Governmental Authority with jurisdiction over the Issuing Bank shall
         prohibit, or request that the Issuing Bank refrain from, the Issuance
         of letters of credit generally or such Letter of Credit in particular
         or shall impose upon the Issuing Bank with respect to such Letter of
         Credit any restriction, reserve or capital requirement (for which the
         Issuing Bank is not otherwise compensated hereunder) not in effect on
         the Effective Date, or shall impose upon the Issuing Bank any



                                       47

<PAGE>   53



         unreimbursed loss, cost or expense which was not applicable on the
         Effective Date and which the Issuing Bank in good faith deems material
         to it;

                  (ii) the Issuing Bank has received written notice from any
         Bank, the Agent or the Borrowers, on or prior to the Business Day prior
         to the requested date of Issuance of such Letter of Credit, that one or
         more of the applicable conditions contained in Article V is not then
         satisfied;

                  (iii) the expiry date of any requested Letter of Credit is (A)
         more than 364 days after the date of Issuance, unless the Majority
         Banks have approved such expiry date in writing, or (B) later than the
         fifth Business Day prior to the Revolving Termination Date, unless all
         of the Banks have approved such expiry date in writing;

                  (iv) any requested Letter of Credit does not provide for
         drafts, or is not otherwise in form and substance acceptable to the
         Issuing Bank, or the Issuance of a Letter of Credit shall violate any
         applicable policies of the Issuing Bank;

                  (v) any standby Letter of Credit is for the purpose of
         supporting the issuance of any letter of credit by any other Person; or

                  (vi) such Letter of Credit is in a face amount less than
         $500,000 (or such lesser amount as may be acceptable to the Issuing
         Bank) or to be denominated in a currency other than Dollars.

         3.2.     ISSUANCE, AMENDMENT AND RENEWAL OF LETTERS OF CREDIT.

                  (a) Each Letter of Credit shall be issued upon the irrevocable
written request of a Borrower received by the Issuing Bank (with a copy sent by
such Borrower to the Agent) at least two Business Days (or such shorter time as
the Issuing Bank may agree in a particular instance in its sole discretion)
prior to the proposed date of issuance. Each such request for issuance of a
Letter of Credit shall be by facsimile, confirmed immediately in an original
writing, in the form of an L/C Application, and shall specify in form and detail
satisfactory to the Issuing Bank: the proposed date of issuance of the Letter of
Credit (which shall be a Business Day); the face amount of the Letter of Credit;
the expiry date of the Letter of Credit; the name and address of the beneficiary
thereof; the documents to be presented by the beneficiary of the Letter of
Credit in case of any drawing thereunder; the full text of any certificate to be
presented by the beneficiary in case of any drawing thereunder; and such other
matters as the Issuing Bank may require.



                                       48

<PAGE>   54



                  (b) At least one Business Day prior to the Issuance of any
Letter of Credit, the Issuing Bank will confirm with the Agent (by telephone or
in writing) that the Agent has received a copy of the L/C Application or L/C
Amendment Application from a Borrower and, if not, the Issuing Bank will provide
the Agent with a copy thereof. Unless the Issuing Bank has received notice on or
before the Business Day immediately preceding the date the Issuing Bank is to
issue a requested Letter of Credit from the Agent (A) directing the Issuing Bank
not to issue such Letter of Credit because such issuance is not then permitted
under SECTION 3.1(a) as a result of the limitations set forth in clauses (1)
through (3) thereof or SECTION 3.1(b)(ii); or (B) that one or more conditions
specified in Article V are not then satisfied; then, subject to the terms and
conditions hereof, the Issuing Bank shall, on the requested date, issue a Letter
of Credit for the account of the applicable Borrower in accordance with the
Issuing Bank's usual and customary business practices.

                  (c) From time to time while a Letter of Credit is outstanding
and prior to the Revolving Termination Date, the Issuing Bank will, upon the
written request of a Borrower received by the Issuing Bank (with a copy sent by
such Borrower to the Agent) at least two days (or such shorter time as the
Issuing Bank may agree in a particular instance in its sole discretion) prior to
the proposed date of amendment, amend any Letter of Credit issued by it. Each
such request for amendment of a Letter of Credit shall be made by facsimile,
confirmed immediately in an original writing, made in the form of an L/C
Amendment Application and shall specify in form and detail satisfactory to the
Issuing Bank: the Letter of Credit to be amended; the proposed date of amendment
of the Letter of Credit (which shall be a Business Day); the nature of the
proposed amendment; and such other matters as the Issuing Bank may require. The
Issuing Bank shall be under no obligation to amend any Letter of Credit if: (A)
the Issuing Bank would have no obligation at such time to issue such Letter of
Credit in its amended form under the terms of this Agreement; or (B) the
beneficiary of any such Letter of Credit does not accept the proposed amendment
to the Letter of Credit. The Agent will promptly notify the Banks of the receipt
by it of any L/C Application or L/C Amendment Application.

                  (d) The Issuing Bank and the Banks agree that, while a Letter
of Credit is outstanding and prior to the Revolving Termination Date, at the
option of a Borrower and upon the written request of such Borrower received by
the Issuing Bank (with a copy sent by such Borrower to the Agent) at least two
days (or such shorter time as the Issuing Bank may agree in a particular
instance in its sole discretion) prior to the proposed date of notification of
renewal, the Issuing Bank shall be entitled to authorize the renewal of any
Letter of Credit issued



                                       49

<PAGE>   55



by it. Each such request for renewal of a Letter of Credit shall be made by
facsimile, confirmed immediately in an original writing, in the form of an L/C
Amendment Application, and shall specify in form and detail satisfactory to the
Issuing Bank: the Letter of Credit to be renewed; the proposed date of
notification of renewal of the Letter of Credit (which shall be a Business Day);
the revised expiry date of the Letter of Credit; and such other matters as the
Issuing Bank may require. The Issuing Bank shall be under no obligation so to
renew any Letter of Credit if: (A) the Issuing Bank would have no obligation at
such time to issue or amend such Letter of Credit in its renewed form under the
terms of this Agreement; or (B) the beneficiary of any such Letter of Credit
does not accept the proposed renewal of the Letter of Credit. If any outstanding
Letter of Credit shall provide that it shall be automatically renewed unless the
beneficiary thereof receives notice from the Issuing Bank that such Letter of
Credit shall not be renewed, and if at the time of renewal the Issuing Bank
would be entitled to authorize the automatic renewal of such Letter of Credit in
accordance with this SECTION 3.2(d) upon the request of a Borrower but the
Issuing Bank shall not have received any L/C Amendment Application from a
Borrower with respect to such renewal or other written direction by such
Borrower with respect thereto, the Issuing Bank shall nonetheless be permitted
to allow such Letter of Credit to renew, and such Borrower and the Banks hereby
authorize such renewal, and, accordingly, the Issuing Bank shall be deemed to
have received an L/C Amendment Application from a Borrower requesting such
renewal.

                  (e) The Issuing Bank may, at its election (or as required by
the Agent at the direction of the Majority Banks), deliver any notices of
termination or other communications to any Letter of Credit beneficiary or
transferee, and take any other action as necessary or appropriate, at any time
and from time to time, in order to cause the expiry date of such Letter of
Credit to be a date not later than the Revolving Termination Date.

                  (f) This Agreement shall control in the event of any conflict
with any L/C-Related Document (other than any Letter of Credit).

                  (g) The Issuing Bank will also deliver to the Agent,
concurrently or promptly following its delivery of a Letter of Credit, or
amendment to or renewal of a Letter of Credit, to an advising bank or a
beneficiary, a true and complete copy of each such Letter of Credit or amendment
to or renewal of a Letter of Credit.

         3.3.     EXISTING BofA LETTERS OF CREDIT; RISK PARTICIPATIONS,
DRAWINGS AND REIMBURSEMENTS.




                                                        50

<PAGE>   56



                  (a) On and after the Effective Date, the Existing BofA Letters
of Credit shall be deemed for all purposes, including for purposes of the fees
to be collected pursuant to SECTIONS 3.8(a) and 3.8(c), and reimbursement of
costs and expenses to the extent provided herein, Letters of Credit outstanding
under this Agreement and entitled to the benefits of this Agreement and the
other Loan Documents, and shall be governed by the applications and agreements
pertaining thereto and by this Agreement. Each Bank shall be deemed to, and
hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank
on the Effective Date a participation in each such Letter of Credit and each
drawing thereunder in an amount equal to the product of such Bank's Pro Rata
Share times the maximum amount available to be drawn under such Letter of Credit
and the amount of such drawing, respectively. For purposes of SECTION 2.1, the
Existing BofA Letters of Credit shall be deemed to utilize pro rata the
Commitment of each Bank.

                  (b) Immediately upon the Issuance of each Letter of Credit in
addition to those described in SECTION 3.3(a), each Bank shall be deemed to, and
hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank
a participation in such Letter of Credit and each drawing thereunder in an
amount equal to the product of the Pro Rata Share of such Bank, times the
maximum amount available to be drawn under such Letter of Credit and the amount
of such drawing, respectively. For purposes of SECTION 2.1, each Issuance of a
Letter of Credit shall be deemed to utilize the Commitment of each Bank by an
amount equal to the amount of such participation.

                  (c) In the event of any request for a drawing under a Letter
of Credit by the beneficiary or transferee thereof, the Issuing Bank will
promptly notify the Borrowers. The applicable Borrower shall reimburse the
Issuing Bank prior to 10:00 a.m. (San Francisco time), on each date that any
amount is paid by the Issuing Bank under any Letter of Credit (each such date,
an "HONOR DATE"), in an amount equal to the amount so paid by the Issuing Bank.
In the event the Borrowers fail to reimburse the Issuing Bank for the full
amount of any drawing under any Letter of Credit by 10:00 a.m. (San Francisco
time) on the Honor Date, the Issuing Bank will promptly notify the Agent and the
Agent will promptly notify each Bank thereof, and the applicable Borrower shall
be deemed to have requested that Base Rate Committed Loans be made by the Banks
to be disbursed on the Honor Date under such Letter of Credit, subject to the
amount of the unutilized portion of the Commitments and subject to the
conditions set forth in SECTION 5.2. Any notice given by the Issuing Bank or the
Agent pursuant to this SECTION 3.3(c) may be oral if immediately confirmed in
writing (including by facsimile); provided that the lack of such an immediate



                                       51

<PAGE>   57



confirmation shall not affect the conclusiveness or binding effect of such
notice.

                  (d) Each Bank shall upon any notice pursuant to SECTION 3.3(c)
make available to the Agent for the account of the relevant Issuing Bank an
amount in Dollars and in immediately available funds equal to its Pro Rata Share
of the amount of the drawing, whereupon the participating Banks shall (subject
to SECTION 3.3(e)) each be deemed to have made a Revolving Loan consisting of a
Base Rate Committed Loan to the applicable Borrower in that amount. If any Bank
so notified fails to make available to the Agent for the account of the Issuing
Bank the amount of such Bank's Pro Rata Share of the amount of the drawing by no
later than 12:00 noon (San Francisco time) on the Honor Date, then interest
shall accrue on such Bank's obligation to make such payment, from the Honor Date
to the date such Bank makes such payment, at a rate per annum equal to the
Federal Funds Rate in effect from time to time during such period. The Agent
will promptly give notice of the occurrence of the Honor Date, but failure of
the Agent to give any such notice on the Honor Date or in sufficient time to
enable any Bank to effect such payment on such date shall not relieve such Bank
from its obligations under this SECTION 3.3.

                  (e) With respect to any unreimbursed drawing that is not
converted into Revolving Loans consisting of Base Rate Committed Loans to a
Borrower in whole or in part, because of the Borrower's failure to satisfy the
conditions set forth in SECTION 5.2 or for any other reason, the applicable
Borrower shall be deemed to have incurred from the Issuing Bank an L/C Borrowing
in the amount of such drawing, which L/C Borrowing shall be due and payable on
demand (together with interest) and shall bear interest at a rate per annum
equal to the Base Rate plus 2% per annum, and each Bank's payment to the Issuing
Bank pursuant to SECTION 3.3(d) shall be deemed payment in respect of its
participation in such L/C Borrowing and shall constitute an L/C Advance from
such Bank in satisfaction of its participation obligation under this SECTION
3.3.

                  (f) Each Bank's obligation in accordance with this Agreement
to make the Revolving Loans or L/C Advances, as contemplated by this SECTION
3.3, as a result of a drawing under a Letter of Credit, shall be absolute and
unconditional and without recourse to the Issuing Bank and shall not be affected
by any circumstance, including any set-off, counterclaim, recoupment, defense or
other right which such Bank may have against the Issuing Bank, the Borrowers or
any other Person for any reason whatsoever; the occurrence or continuance of a
Default, an Event of Default or a Materially Adverse Effect; or any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing; PROVIDED, HOWEVER, that each



                                       52

<PAGE>   58



Bank's obligation to make Revolving Loans under this SECTION 3.3 is subject to
the conditions set forth in SECTION 5.2. Each Bank's obligations under this
clause (f) are several and not joint or joint and several, and no Bank shall be
responsible for the failure of any other Bank to satisfy its obligations under
this clause (f).

         3.4.     REPAYMENT OF PARTICIPATIONS.

                  (a) Upon (and only upon) receipt by the Agent for the account
of the Issuing Bank of immediately available funds from the Borrowers in
reimbursement of any payment made by the Issuing Bank under the Letter of Credit
with respect to which any Bank has paid the Agent for the account of the Issuing
Bank for such Bank's participation in the Letter of Credit pursuant to SECTION
3.3 or in payment of interest thereon, the Agent will pay to each Bank, in the
same funds as those received by the Agent for the account of the Issuing Bank,
the amount of such Bank's Pro Rata Share of such funds, and the Issuing Bank
shall receive the amount of the Pro Rata Share of such funds of any Bank that
did not so pay the Agent for the account of the Issuing Bank.

                  (b) If the Agent or the Issuing Bank is required at any time
to return to the Borrowers, or to a trustee, receiver, liquidator, custodian, or
any official in any Insolvency Proceeding, any portion of the payments made by a
Borrower to the Agent for the account of the Issuing Bank pursuant to this
SECTION 3.4 in reimbursement of a payment made under the Letter of Credit or
interest or fee thereon, each Bank shall, on demand of the Agent, forthwith
return to the Agent or the Issuing Bank the amount of its Pro Rata Share of any
amounts so returned by the Agent or the Issuing Bank plus interest thereon from
the date such demand is made to the date such amounts are returned by such Bank
to the Agent or the Issuing Bank, at a rate per annum equal to the Federal Funds
Rate in effect from time to time.

         3.5.     ROLE OF THE ISSUING BANK.

                  (a) Each Bank and the Borrowers agree that, in paying any
drawing under a Letter of Credit, the Issuing Bank shall not have any
responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document.

                  (b) No Agent-Related Person nor any of the respective
correspondents, participants or assignees of the Issuing Bank shall be liable to
any Bank for: any action taken or omitted in connection herewith at the request
or with the approval of the



                                       53

<PAGE>   59



Banks (including the Majority Banks, as applicable); any action taken or omitted
in the absence of gross negligence or willful misconduct; or the due execution,
effectiveness, validity or enforceability of any L/C-Related Document.

                  (c) The Borrowers hereby assume all risks of the acts or
omissions of any beneficiary or transferee with respect to its use of any Letter
of Credit; PROVIDED, HOWEVER, that this assumption is not intended to, and shall
not, preclude the Borrowers' pursuing such rights and remedies as they may have
against the beneficiary or transferee at law or under any other agreement. No
Agent-Related Person, nor any of the respective correspondents, participants or
assignees of the Issuing Bank, shall be liable or responsible for any of the
matters described in clauses (i) through (vii) of SECTION 3.6; PROVIDED,
HOWEVER, anything in such clauses to the contrary notwithstanding, that the
Borrowers may have a claim against the Issuing Bank, and the Issuing Bank may be
liable to the Borrowers, to the extent, but only to the extent, of any direct,
as opposed to consequential or exemplary, damages suffered by the Borrowers
which the Borrowers prove were caused by the Issuing Bank's willful misconduct
or gross negligence or the Issuing Bank's willful failure to pay under any
Letter of Credit after the presentation to it by the beneficiary of a sight
draft and certificate(s) strictly complying with the terms and conditions of a
Letter of Credit. In furtherance and not in limitation of the foregoing: the
Issuing Bank may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary; and the Issuing Bank shall not be responsible for
the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

         3.6.     OBLIGATIONS ABSOLUTE. The obligations of the Borrowers under 
this Agreement and any L/C-Related Document to reimburse the Issuing Bank for a
drawing under a Letter of Credit, and to repay any L/C Borrowing and any drawing
under a Letter of Credit converted into Revolving Loans, shall be unconditional
and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement and each such other L/C-Related Document under all circumstances,
including the following:

                  (i) any lack of validity or enforceability of this Agreement
         or any L/C-Related Document;

                  (ii) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the obligations of the Borrowers in
         respect of any Letter of Credit or any other amendment or waiver of or
         any



                                       54

<PAGE>   60



         consent to departure from all or any of the L/C-Related Documents;

                  (iii) the existence of any claim, set-off, defense or other
         right that the Borrowers may have at any time against any beneficiary
         or any transferee of any Letter of Credit (or any Person for whom any
         such beneficiary or any such transferee may be acting), the Issuing
         Bank or any other Person, whether in connection with this Agreement,
         the transactions contemplated hereby or by the L/C-Related Documents or
         any unrelated transaction;

                  (iv) any draft, demand, certificate or other document
         presented under any Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect; or any loss or delay in the
         transmission or otherwise of any document required in order to make a
         drawing under any Letter of Credit;

                  (v) any payment by the Issuing Bank under any Letter of Credit
         against presentation of a draft or certificate that does not strictly
         comply with the terms of any Letter of Credit; or any payment made by
         the Issuing Bank under any Letter of Credit to any Person purporting to
         be a trustee in bankruptcy, debtor-in-possession, assignee for the
         benefit of creditors, liquidator, receiver or other representative of
         or successor to any beneficiary or any transferee of any Letter of
         Credit, including any arising in connection with any Insolvency
         Proceeding;

                  (vi) any release or amendment or waiver of or consent to
         departure from any other guarantee, for all or any of the obligations
         of the Borrowers in respect of any Letter of Credit; or

                  (vii) any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, the Borrowers or a guarantor.

         3.7.     CASH COLLATERAL PLEDGE.  Upon the request of the Agent,

                  (i) (A) while an Event of Default exists, if the Issuing Bank
         has honored any full or partial drawing request on any Letter of Credit
         and such drawing has resulted in an L/C Borrowing hereunder, or (B) if,
         as of the Revolving Termination Date, any Letters of



                                       55

<PAGE>   61



         Credit may for any reason remain outstanding and partially or wholly
         undrawn, or

                  (ii) the occurrence of the circumstances described in SECTION
         2.9 requiring the Borrowers to Cash Collateralize Letters of Credit,
         then, the Borrowers shall immediately Cash Collateralize the L/C
         Obligations in an amount equal to such L/C Obligations.

         3.8.     LETTER OF CREDIT FEES.

                  (a) The Borrowers shall pay to the Agent for the account of
each of the Banks a letter of credit fee on average daily maximum amount
available to be drawn of the outstanding Letters of Credit, computed on a
quarterly basis in arrears on the last Business Day of each calendar quarter
based upon Letters of Credit outstanding for that quarter as calculated by the
Agent, at a rate per annum equal to the Applicable Letter of Credit Fee Rate.
Such letter of credit fees shall be due and payable quarterly in arrears on the
last Business Day of each calendar quarter during which Letters of Credit are
outstanding, commencing on September 30, 1998, through the Revolving Termination
Date (or such later date upon which the outstanding Letters of Credit shall
expire), with the final payment to be made on the Revolving Termination Date (or
such later expiration date).

                  (b) The Borrowers shall pay to the Issuing Bank a letter of
credit fronting fee for each Letter of Credit Issued by the Issuing Bank equal
to .125 of 1% of the face amount (or increased face amount, as the case may be)
of such Letter of Credit. Such Letter of Credit fronting fee shall be due and
payable on each date of Issuance of a Letter of Credit.

                  (c) The Borrowers shall pay to the Issuing Bank from time to
time on demand the normal Issuance, presentation, amendment and other processing
fees, and other standard costs and charges, of the Issuing Bank relating to
Letters of Credit as from time to time in effect.

         3.9.     UNIFORM CUSTOMS AND PRACTICE. The Uniform Customs and Practice
for Documentary Credits as published by the International Chamber of Commerce
most recently at the time of issuance of any Letter of Credit shall (unless
otherwise expressly provided in the Letters of Credit) apply to the Letters of
Credit.

                     TAXES, YIELD PROTECTION AND ILLEGALITY



                                       56

<PAGE>   62



         4.1.     TAXES.

                  (a) Any and all payments by the Borrowers to each Bank,
Designated Bidder, 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, Designated Bidder, 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, Designated Bidder, 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, Designated Bidder, 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, Designated Bidder, 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, Designated Bidder, 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, Designated
         Bidder, Tax Transferee or the Agent for the account of such Bank,
         Designated Bidder or Tax Transferee, at the time interest is paid, all
         additional amounts which the respective Bank or Designated Bidder
         specifies as necessary to preserve the after-tax yield the Bank,
         Designated Bidder or Tax Transferee would have received if such Taxes
         or Other Taxes had not been imposed.



                                       57

<PAGE>   63



                  (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
4.1 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. Section 1.881-3.

         4.2.     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, or
such Bank's Designated Bidders in the case of LIBOR Bid Loans, to make Offshore
Rate Loans, then, on notice thereof by the Bank to the Borrowers through the
Agent, any obligation of that Bank or Designated Bidder to make Offshore Rate
Loans (including in respect of any LIBOR Bid Loan as to which the Borrowers have
accepted such Bank's or Designated Bidder's Competitive Bid, but as to which the
Borrowing Date has not arrived) shall be suspended until the Bank notifies the
Agent and the Borrowers that the circumstances giving rise to such determination
no longer exist.




                                       58

<PAGE>   64



                  (b) If it is unlawful to maintain any Offshore Rate Loan, the
Borrowers shall, upon receipt of notice of such fact 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 4.4, 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.

         4.3.     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 or participating in Letters of Credit, or, in the
case of the Issuing Bank, any increase in the cost to the Issuing Bank of
agreeing to issue, issuing or maintaining any Letter of Credit or of agreeing to
make or making, funding or maintaining any unpaid drawing under any Letter of
Credit, 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



                                       59

<PAGE>   65



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.

         4.4. 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 2.9;

                  (d) the prepayment (including pursuant to SECTION 2.9) or
other payment (including after acceleration thereof) of any Offshore Rate Loan
or Absolute Rate Bid 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 4.3(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.

         4.5.     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



                                       60

<PAGE>   66



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 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.

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

         4.7.     SUBSTITUTION OF BANKS. Upon the receipt by the Borrowers from
any Bank (an "Affected Bank") of a claim for compensation under SECTION 4.1 or
SECTION 4.3 or in the event any Bank whose obligations to make Offshore Loans
have been suspended under SECTION 4.2, 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).

        4.8.      AFFECTED BANK'S OBLIGATION TO MITIGATE. Each Bank and
Designated Bidder 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 4.1
(b) or (c) or (b) it to be illegal for such Bank or Designated Bidder to make or
maintain any Offshore Rate Loan, it will, to the extent not inconsistent with
such Bank's or Designated Bidder's internal policies, use its reasonable efforts
to make, fund or maintain the affected Loans of such Bank or Designated Bidder
through another Lending Office of such Bank or Designated Bidder if as a result
thereof the additional moneys which would otherwise be required to be paid in
respect of such Loans pursuant to SECTION 4.1(c) would be materially reduced or
the illegality or other adverse circumstances which would otherwise require
prepayment of such Loans pursuant to SECTION 4.2, and if, as such Bank or



                                       61

<PAGE>   67



Designated Bidder determines, in its sole discretion, the making, funding or
maintaining of such Loans through such Lending Office would not, in the judgment
of such Bank or Designated Bidder, be disadvantageous to such Bank or Designated
Bidder. The Borrowers hereby agree to pay all reasonable expenses incurred by
any Bank or Designated Bidder in utilizing another Lending Office pursuant to
this SECTION 4.8.

         4.9.     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 IV (each, a "TRIGGER EVENT"). Notwithstanding any other
provision of this Article IV, 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.

                         REPRESENTATIONS AND WARRANTIES

         The Company hereby represents and warrants to the Agent and each Bank
that:

         6.1.     ORGANIZATION, POWER, AUTHORITY, ETC. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the state of Delaware, is duly qualified to do business and is in good
standing as a foreign corporation in each jurisdiction where the failure so to
qualify would be reasonably likely to have a Materially Adverse Effect, and has
full power and authority and holds all requisite governmental licenses, permits

business substantially as currently conducted by it where the failure to hold
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

to partnerships in any such jurisdiction), is duly qualified to do business and

where the failure so to qualify would be reasonably likely to have a Materially
Adverse Effect, and has full power and authority and holds all requisite
governmental licenses, permits and other approvals to own and hold under lease
its property and to conduct its business substantially as currently conducted by
it where the failure to hold such licenses, permits, and other approvals would
be reasonably likely to have a Materially Adverse Effect. Each of the Company
and each other Obligor has full power and authority to execute, deliver and
perform its Obligations under this Agreement, the Notes and each other Loan
Document to which it is or is to be a party, to obtain Credit Extensions
hereunder, and all other actions incidental thereto, as applicable.

all Credit Extensions obtained hereunder by the Borrowers, the execution,
delivery and performance by each other Obligor of each Loan Document executed or
to be executed by it, and all other actions incidental to any thereof have been
duly authorized by all necessary action, do not and will not conflict with,
result in any violation of, or constitute any default under, any provision of
any Organization Document or material Contractual Obligation of the Company or
such Obligor or any law or



                                       66

<PAGE>   72



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).

it is or is to be a party or the consummation of any other transactions
contemplated hereby or thereby, except for authorizations, approvals, actions,
notices or filings which have been duly obtained or made and are in full force

delivered by the Borrowers and constitutes the legal, valid and binding
obligation of the Borrowers enforceable in accordance with its terms; and each
Note and each other Loan Document to which the Borrowers or any other Obligor is
or is to be a party will, on the due execution and delivery thereof, constitute
the legal, valid and binding obligation of the Borrowers or such Obligor, as the
case may be, enforceable in accordance with its terms; except, in each case, as
enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or limiting creditors' rights generally or by
equitable principles relating to enforceability.

of the Company, threatened litigation, action, proceeding, order, investigation
or claim, at law or in equity or before or by any governmental department,
commission, board, bureau, agency or instrumentality affecting the Company or
any of the other Obligors, or any of their respective properties, assets or

                                       69

<PAGE>   75



occurred which, with the giving of notice under Section 4219 of ERISA, would

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

proceedings and for which adequate reserves in accordance with GAAP shall have
been set aside on its books.

         6.12.    ABSENCE OF DEFAULT. Neither the Company nor any other Obligor

other Obligor, which would be reasonably likely to have a Materially Adverse

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 7.2.3 and, as of
the Effective Date, as disclosed in ITEM 7.2.2(l)/7.2.3(a) ("Existing
Indebtedness and Existing Liens") of the Disclosure Schedule and except for

         6.15.    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

                                       70

Trademark Infringements") of the Disclosure Schedule.

         6.16.    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 6.16 ("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.

         6.17.    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 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.

         6.18.    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.

         6.19.    HEALTH CARE REGULATORY MATTERS.

                  (a) Except as disclosed in ITEM 6.19 ("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 obligations with respect to
         Hill-Burton Act charity care.

                  (b) Except as disclosed in ITEM 6.19 ("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 6.19 ("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



                                       72

<PAGE>   78



adversely affect such Certification or the Medicare Provider Agreement or
Medicaid Provider Agreement with respect to such Facility.

         6.20.    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

                  (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.

Each of the financial statements referred to in SECTIONS 7.1.1(a), 7.1.1(b) and
7.1.1(C) will fairly present the financial position of the Company and its
Subsidiaries as of the dates and for the periods stated therein, subject, in the

permitted by SECTION 7.2.6 or 7.2.7, 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 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 7.2.3), all of the

other Obligor and each Subsidiary of the Obligors to, pay and discharge, as the

provide a release of the Guaranty or, if applicable, the Manor Care Subsidiary
Guarantee,



                                       85

<PAGE>   91

cause, suffer or permit to exist, any arrangement or contract with any of its

such other Obligor or such Subsidiary and is not of a sort which would not be
entered into by a prudent Person in the position of the Company or such other
Obligor or such Subsidiary with, or which is on terms which are less favorable
than are obtainable from, any Person which is not one of its Affiliates;
provided, however, that nothing in this SECTION 7.2.9 shall restrict (i)

to, enter into any agreement (other than a Loan Document) which (a) except with
respect to specific property encumbered to secure payment of Indebtedness

restrictions greater in the aggregate than those under this Agreement upon the
creation or assumption of any Lien upon its properties, revenues or assets,

<PAGE>   92



will not permit any Person to, except in accordance with Applicable Law, dispose
of any Hazardous Material into, onto or from any real property owned or operated
by the Company or any other Obligor or any Subsidiary of the Obligors, nor allow
any Lien imposed pursuant to any law, regulation or order relating to Hazardous
Materials or the disposal thereof to remain on such real property, which
disposal or Lien would be reasonably likely to have a Materially Adverse Effect.

         7.2.12.  ACQUISITIONS. The Company will not, nor will it permit any of
its Subsidiaries to, make any Acquisition unless:

                  (i) immediately before and after giving effect to the

         continuing or will exist;

                  (ii) for each such Acquisition involving the purchase of a
         majority of the stock of another party, the prior, effective written
         consent or approval to such Acquisition of the board of directors or
         equivalent governing body of the other party or parties has been
         obtained; and

                  (iii) the aggregate value of the cash or other non-stock
         consideration (including Indebtedness assumed by the Company or its

         than those described in the following proviso) does not exceed
         $150,000,000 in any fiscal year;

PROVIDED, HOWEVER, that notwithstanding the foregoing, any Subsidiary of the
Company may be merged or consolidated with or into the Company if the Company
shall be the continuing or surviving corporation or with or into any other
Subsidiary of the Company.

shall, at the request of, or may, with the consent of, the
Majority Banks,

                  (a) declare the commitment of each Bank to make Loans and any
obligation of the Issuing Bank to Issue Letters of Credit to be terminated,
whereupon such commitments and obligation shall be terminated;

                  (b) declare an amount equal to the maximum aggregate amount
that is or at any time thereafter may become available for drawing under any
outstanding Letters of Credit (whether or not any beneficiary shall have

documents required to draw under such Letters of Credit) to be immediately due
and payable, and declare the unpaid principal amount of all outstanding Loans,
all interest accrued and unpaid thereon, and



                                       90

<PAGE>   96



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 8.1.4, the obligation of each Bank to make Loans and
any obligation of the Issuing Bank to Issue Letters of Credit shall
automatically terminate and the unpaid principal amount of all outstanding Loans
and all interest and other amounts as aforesaid shall automatically become due
and payable without further act of the Agent, the Issuing Bank or any Bank.

         8.3.     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 IX

                                    THE AGENT

         9.1.     APPOINTMENT AND AUTHORIZATION.

                  (a) 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.

                  (b) The Issuing Bank shall act on behalf of the Banks with
respect to any Letters of Credit Issued by it and the documents associated
therewith until such time and except for so long as the Agent may agree at the
request of the Majority Banks



                                                        91

<PAGE>   97



to act for such Issuing Bank with respect thereto; PROVIDED, HOWEVER, that the
Issuing Bank shall have all of the benefits and immunities (i) provided to the
Agent in this Article IX with respect to any acts taken or omissions suffered by
the Issuing Bank in connection with Letters of Credit Issued by it or proposed
to be Issued by it and the application and agreements for letters of credit
pertaining to the Letters of Credit as fully as if the term "Agent", as used in
this Article IX, included the Issuing Bank with respect to such acts or
omissions, and (ii) as additionally provided in this Agreement with respect to
the Issuing Bank.

         9.2.     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.

         9.3.     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 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.

         9.4.     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



                                       92

<PAGE>   98



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 5.1, 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.

         9.5.     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 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 VIII; 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.

         9.6.     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



                                       93

<PAGE>   99



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.

         9.7.     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 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.

         9.8.     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,



                                       94

<PAGE>   100



underwriting or other business with the Company and its Subsidiaries and
Affiliates as though BofA were not the Agent or the Issuing Bank 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 or the Issuing Bank, and the terms "Bank" and
"Banks" include BofA in its individual capacity.

         9.9.     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 IX and
SECTIONS 10.4 and 10.5 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this 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. Notwithstanding
the foregoing, however, BofA may not be removed as the Agent at the request of
the Majority Banks unless BofA shall also simultaneously be replaced as "Issuing
Bank" hereunder pursuant to documentation in form and substance reasonably
satisfactory to BofA.

         9.10.    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



                                       95

<PAGE>   101



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 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



                                       96

<PAGE>   102



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.

         9.11.    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 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.

         10.1.    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 8.2);

                  (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 2.11(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 2.16, or any provision
herein providing for consent or other action by all Banks; or

                  (f) except as provided in SECTION 7.2.7 or in accordance with
their respective terms, terminate the Guaranty or the Manor Care Subsidiary

and, PROVIDED FURTHER, that (i) no amendment, waiver or consent shall, unless in

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.

                  (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 10.2, 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
10.2; 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

notices pursuant to Article II or IX 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 the Agent and the Banks to be contained in the telephonic or
facsimile notice.

         10.3.    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.

         10.4.    COSTS AND EXPENSES.  The Company shall:




                                       99

<PAGE>   105



                  (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 5.1(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 5.1(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).

         10.5.    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 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



                                       100

<PAGE>   106



Indemnified Person.  The agreements in this Section shall survive
payment of all other Obligations.

         10.6.    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.

         10.7.    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.

         10.8.    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 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



                                       101

<PAGE>   107



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 10.8(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 or Designated Bidder 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 or Designated Bidder (the "ORIGINATOR")
hereunder and under the other Loan Documents; 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



                                       102

<PAGE>   108



amendment, consent or waiver would require unanimous consent of the Banks as
described in the first proviso to SECTION 10.1. In the case of any such
participation, the Participant shall be entitled to the benefit of SECTIONS 4.1,
4.3 and 10.5 as though it were also a Bank or Designated Bidder (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 or Designated Bidder (as the case
may be) under this Agreement.

                  (e) Notwithstanding any other provision in this Agreement, any
Bank or Designated Bidder 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.

         10.9.    DESIGNATED BIDDERS. Any Bank may designate one Designated 
Bidder to have a right to offer and make Bid Loans pursuant to SECTION 2.6;
PROVIDED, HOWEVER, that (i) no such Bank may make more than one such
designation, (ii) each such Bank making any such designation shall retain the
right to make Bid Loans, and (iii) the parties to each such designation shall
execute and deliver to the Agent a Designation Agreement. Upon its receipt of an
appropriately completed Designation Agreement executed by a designating Bank and
a designee representing that it is a Designated Bidder, the Agent will accept
such Designation Agreement and give prompt notice thereof to the Company,
whereupon such designation of such Designated Bidder shall become effective and
shall become a party to this Agreement as a "Designated Bidder."

         10.10.   CONFIDENTIALITY. Each Bank and Designated Bidder 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



                                       103

<PAGE>   109



as a result of disclosure by the Bank or Designated Bidder, 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 or Designated Bidder; PROVIDED, HOWEVER, that
any Bank or Designated Bidder may disclose such information (A) at the request
or pursuant to any requirement of any Governmental Authority to which the Bank
or Designated Bidder is subject or in connection with an examination of such
Bank or Designated Bidder 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, Designated Bidder or their respective 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 or Designated Bidder'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 Designated Bidder
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 Designated Bidder or such Affiliate;
and (I) to its Affiliates subject to confidentiality and only for use in
connection herewith.

         10.11.   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 and Designated Bidder 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 or Designated Bidder to or for the credit or the account of the Borrowers
against any and all Obligations owing to such Bank or Designated Bidder, now or
hereafter existing, irrespective of whether or not the Agent or such Bank or
Designated Bidder shall have made demand under this Agreement or any Loan
Document and although such Obligations may be contingent or unmatured. Each Bank
and Designated Bidder agrees promptly to notify the Borrowers and the Agent
after any such set-off and application made by such Bank or Designated Bidder;
PROVIDED, HOWEVER, that the failure to give such notice shall not affect the
validity of such set-off and application.




                                       104

<PAGE>   110



         10.12.   NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC. Each Bank and
Designated Bidder shall notify the Agent in writing of any changes in the
address to which notices to the Bank and Designated Bidder 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.

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

         10.14.   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.

         10.15.   NO THIRD PARTIES BENEFITED. This Agreement is made and entered
into for the sole protection and legal benefit of the Borrowers, the Banks, the
Designated Bidders, 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.

         10.16.   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
AND THE BANKS CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE BORROWERS, THE AGENT,
THE DESIGNATED BIDDERS 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, THE DESIGNATED BIDDERS AND THE BANKS
EACH WAIVE PERSONAL SERVICE OF



                                       105

<PAGE>   111



ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS
PERMITTED BY NEW YORK LAW.

         10.17.   WAIVER OF JURY TRIAL. THE BORROWERS, THE BANKS, THE DESIGNATED
BIDDERS 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 WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS,
OR OTHERWISE. THE BORROWERS, THE BANKS, THE DESIGNATED BIDDERS 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.

         10.18.   ENTIRE AGREEMENT. This Agreement, together with the other Loan
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
matter hereof and thereof.

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>   123



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 7.1.1(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 VII 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>   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 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>   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
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 10.8 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.





<PAGE>   126



         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 abso-
lute 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.

notices by telephone or facsimile is solely for the convenience and at the
request of the Guarantors. The Agent and the Banks shall be entitled to rely on
the authority of any Person purporting to be a Person authorized by the
Guarantors to give such notice and the Agent and the Banks shall not have any
liability to the Guarantors 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 obligations of the Guarantors under this Guaranty 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

with the terms understood by the Agent and the Banks to be contained in the
telephonic or facsimile notice.

NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION

                                    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
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 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>   150



Section 502(b) and Section 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 7.1.1(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 VII 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>   151



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>   152



         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 26. TRANSFER OF OBLIGATIONS. Subject to Section 10.8 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.





<PAGE>   153



         SECTION 27. 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 abso-
lute and unconditional irrespective of any circumstance whatsoever which might
constitute a legal or equitable discharge or defense of Manor Care. Each
Guarantor hereby acknowledges that there are no conditions to the effectiveness
of this Guaranty.

         SECTION 28. 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 Manor Care, 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 Manor
Care 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 29. 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 30. NOTICES.

         a. All notices, requests and other communications shall be in writing

recipient at the number specified on SCHEDULE 10.2 of the Credit Agreement, and

         b. All such notices, requests and communications shall, when

         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 Guarantors. The Agent and the Banks shall be entitled to rely on
the authority of any Person purporting to be a Person authorized by the
Guarantors to give such notice and the Agent and the Banks shall not have any
liability to the Guarantors 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 obligations of the Guarantors under this Guaranty 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 the Agent and the Banks to be contained in the
telephonic or facsimile notice.

         SECTION 31. GOVERNING LAW AND JURISDICTION. THIS GUARANTY SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK

SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION AND DELIVERY OF THIS GUARANTY,
EACH OF THE GUARANTORS, THE AGENT AND THE BANKS CONSENTS, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH
OF THE GUARANTORS, 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 GUARANTY OR ANY DOCUMENT
RELATED HERETO. THE GUARANTORS, THE AGENT AND THE BANKS EACH WAIVE PERSONAL
SERVICE OF ANY SUMMONS, COMPLAINT OR




<PAGE>   155



OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

         SECTION 32. WAIVER OF JURY TRIAL. THE GUARANTORS, 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 GUARANTY 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 WITH RESPECT TO
CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE GUARANTORS, 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 GUARANTY
OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,

                                    GUARANTY
                                    --------

executed by the undersigned (the "GUARANTOR") in favor of Bank of America
National Trust and Savings Association, as Agent (as hereinafter defined in the

                                    RECITALS
                                    --------

         WHEREAS, the Guarantor, 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 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, 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
consolidated group of which the Guarantor is a part,

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

         SECTION 35. GUARANTY.

         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
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

<PAGE>   163




         b. The liability of the Guarantor 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 the Guarantor, due consideration
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
Guarantor notwithstanding the dissolution of any other 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 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.

         SECTION 37. [Intentionally omitted]

         SECTION 38. 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 without notice to the 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 Guarantor's 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)



                                        5

<PAGE>   164



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 the 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 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.

         b. To the extent permitted by Applicable Law, the 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 the Guarantor
hereunder.

the Agent and the Banks that (i) it now has and expects to continue to have

information concerning the affairs, financial condition or business of Manor
Care which may come into such Person's possession; (ii) the execution, delivery
