ITEM 5.  OTHER EVENTS.

         Omnicare, Inc. (the "Company") entered into an Amendment No. 2 to
Credit Agreement dated as of December 21, 1998 (the "Amendment"), with certain
banks (the "Banks") and The First National Bank of Chicago, as one of the Banks
and agent for the Banks (the "Agent"). The Amendment amends the Credit Agreement
dated as of October 22, 1996, among the Borrower, the Banks and the Agent (the
"Original Credit Agreement"), as previously amended, to provide for, among other
things, (i) an increase in the commitment fee rate, the letter of credit fee
rate and the interest rate margin, and (ii) the imposition of a utilization fee
on the outstanding loans under the Original Credit Agreement. The Company also
entered into a 364-Day Credit Agreement dated as of December 21, 1998 (the "1998
Credit Agreement"), with certain banks (the "Lenders") and the Agent as one of
the Lenders and agent for the Lenders. The 1998 Credit Agreement provides for an
additional revolving line of credit in the principal amount of up to
$400,000,000 for a term of 364-days that may, at the option of the Company, be
converted at maturity into a one-year term loan. Except for the commitment fee
rate, the interest rate margin and other pricing terms, the representations,
warranties and covenants of the Company in the 1998 Credit Agreement are
substantially the same as the Original Credit Agreement as amended by the
Amendment.

      following new SECTION 5.17 at the end thereof:

                           5.17. YEAR 2000. The Borrower and its Subsidiaries
                  have made an assessment of the Year 2000 Issues and in good
                  faith believe they have a realistic and achievable program for
                  remediating the Year 2000 Issues on a timely basis and a
                  reasonable contingency plan to address any inability of
                  computer applications in the computer systems of their
                  material customers, suppliers and vendors to effectively
                  handle data including dates on and after January 1, 2000.
                  Based on such assessment and program, the Borrower and its
                  Subsidiaries do not reasonably anticipate that Year 2000

                  definition of "Indebtedness") of any Guarantor, (e) Contingent
                  Obligations incurred by any Guarantor in respect of

                  6.14(m), not to exceed in the aggregate more than 5% of
                  Consolidated Net Worth; PROVIDED, HOWEVER, that nothing
                  contained in this SECTION 6.15 shall prohibit any Subsidiary
                  of the Borrower that is a Guarantor from also guaranteeing the

                  to assure that the Year 2000 Issues will not have a Material
                  Adverse Effect and to implement their contingency plan to
                  address any inability of computer applications in the computer
                  systems of their material customers, suppliers and vendors to
                  effectively handle data including dates on and after January
                  1, 2000. The Borrower, on behalf of itself and its
                  Subsidiaries, will promptly notify the Agent in writing of any
                  reasonably anticipated Material Adverse Effect as a result of
                  Year 2000 Issues or as a result of any such inability with
                  respect to their material customers, suppliers and vendors.

                  (o) SECTION 9.6 of the Credit Agreement is amended by deleting

going business or all or substantially all of the assets of any firm,
corporation or division thereof which constitutes a going business, whether
through purchase of assets, merger or otherwise or (b) directly or indirectly
acquires (in one transaction or as the most recent transaction in a series of
transactions) at least a majority (in number of votes) of the securities of a
corporation which have ordinary voting power for the election of directors
(other than securities having such power only by reason of the happening of a
contingency) or a majority (by percentage or voting power) of the outstanding
partnership interests of a partnership or a majority (by percentage or voting
power) of the outstanding ownership interests of a limited liability company.

                  "ADVANCE" means a borrowing consisting of simultaneous Loans
of the same Type made to the Borrower by each of the Lenders pursuant to SECTION

                  "AFFILIATE" of any Person means any other Person directly or
indirectly controlling, controlled by or under common control with such Person.
A Person shall be deemed to control another Person if the controlling Person

                  2.1. THE LOANS. From and including the date of this Agreement
and prior to the Revolving Credit Termination Date, each Lender severally
agrees, on the terms and conditions set forth in this Agreement (including,
without limitation, the terms and conditions of SECTION 2.9 and SECTION 8.1
relating to the reduction, suspension or termination of the Aggregate
Commitment), to make Loans to the Borrower from time to time in an aggregate
amount not to exceed at any one time outstanding the amount of such Lender's
Commitment. Subject to the terms of this Agreement (including, without
limitation, the terms and conditions of SECTION 2.9 and SECTION 8.1 relating to
the reduction, suspension or termination of the Aggregate Commitment), the
Borrower may borrow, repay and reborrow Loans at any time prior to the Revolving

the Revolving Credit Termination Date. Principal payments made after the

                  2.2 REPAYMENT OF THE LOANS . The Revolving Credit Termination
Balance shall be paid in full by the Borrower on the Revolving Credit
Termination Date; PROVIDED, HOWEVER, that (a) Loans may be prepaid prior to the
Revolving Credit Termination Date in accordance with the terms of this Agreement
and (b) the Revolving Credit Termination Balance may be consolidated and
converted into a single one-year term loan (the "TERM LOAN OPTION"). The
Borrower may elect the Term Loan Option by providing written notice of such
election to the Agent and Lenders at least thirty days prior to the Revolving
Credit Termination Date. Upon such election, the Revolving Credit Termination
Balance shall be converted into a one-year term loan payable in four equal,
consecutive quarterly installments of principal, on March 20, 2000, June 20,
2000, September 20, 2000, and on the Facility Termination Date. All unpaid
Obligations shall be paid in full by the Borrower on the Facility Termination
Date. All other provisions of this Agreement shall apply to such term loans,
including, without limitation, interest rate options and interest payment
provisions pursuant to SECTIONS 2.7 and 2.8. Notwithstanding the foregoing, the
Term Loan Option shall not be available to the Borrower if a Default or
Unmatured Default has occurred or is continuing as of the date of the Revolving
Credit Termination Date.

                  2.3. RATABLE LOANS; TYPES OF ADVANCES . Each Advance hereunder
shall consist of Loans made from the several Lenders ratably in proportion to
the ratio that their respective Commitments bear to the Aggregate Commitment.
Any Advance may be a Floating Rate Advance or a Eurodollar Advance, as the
Borrower shall select in accordance with SECTIONS 2.6 and 2.7.

                  2.4. MINIMUM AMOUNT OF EACH ADVANCE . Each Advance shall be in
a minimum amount not less than $15,000,000 or an integral multiple of $1,000,000
in excess thereof; PROVIDED, HOWEVER, that any Advance may be in the amount of
the unused Aggregate Commitment.

                  2.5. OPTIONAL PREPAYMENTS OF LOANS . Subject to SECTION 3.4
and the requirements of SECTION 2.4, the Borrower may (a) following notice given
to the Agent by the Borrower, in the form attached hereto as EXHIBIT G (a
"PREPAYMENT NOTICE") by not later than 10:00 a.m. (Chicago time) one Business
Day prior to the date of the proposed prepayment, such notice specifying the
aggregate principal amount of and the proposed date of the prepayment, and if
such notice is given the Borrower shall, prepay the outstanding principal
amounts of the Floating Rate Loans comprising part of the same Advance in whole
or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid and (b) following a Prepayment Notice
given to the Agent by the Borrower by not later than 10:00 a.m. (Chicago time)
on, if the Advance to be prepaid is a Eurodollar Advance, the third Business Day
preceding the date of the proposed prepayment, such notice specifying the
Advance to be prepaid and the proposed date of the prepayment, and, if such
notice is given, such Borrower shall, prepay the outstanding principal amounts
of the Eurodollar Loans comprising a Eurodollar Advance in whole (and not in
part), together with accrued interest to the date of such prepayment on the
principal amount prepaid. In the case of a Floating Rate Advance, each partial
prepayment shall be in an aggregate principal amount not less than $1,000,000.

                  2.6. METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW
ADVANCES . The Borrower shall select the Type of each Advance and, in the case
of a Eurodollar Advance, the Interest Period applicable to such Advance from
time to time. The Borrower shall give the Agent irrevocable notice, in the form
attached hereto as EXHIBIT F (a "BORROWING NOTICE"), not later than 10:00 a.m.
(Chicago time) (i) on the Borrowing Date for each Floating Rate Advance and (ii)
at least three Business Days before the Borrowing Date for each Eurodollar
Advance, specifying:

                  (a) the Borrowing Date, which shall be a Business Day, of such
         Advance,

                  (b) the aggregate amount of such Advance,

                  (c) the Type of such Advance, and

                  (d) in the case of each Eurodollar Advance, the Interest
         Period applicable thereto.

Not later than the Specified Remittance Time on each Borrowing Date, each Lender
shall make available its Loan or Loans to the Agent in immediately available
funds at the relevant Payment 


                                       9
<PAGE>   15



Office. To the extent that the Agent has received funds from the Lenders as
specified in the preceding sentence and the applicable conditions set forth in
ARTICLE IV have been fulfilled, the Agent will make such funds available to the
Borrower at the relevant Payment Office within two hours following the Specified
Remittance Time, it being understood that if the relevant Payment Office is
located in Chicago, the Agent will make the applicable funds available to the
Borrower by depositing such funds to such account with First Chicago as the
Borrower shall designate.

                  2.7. CONVERSION AND CONTINUATION OF OUTSTANDING ADVANCES .
Floating Rate Advances shall continue as Floating Rate Advances unless and until
such Floating Rate Advances are converted into Eurodollar Advances or prepaid
pursuant to SECTION 2.5. Each Eurodollar Advance of any Type shall continue as a
Eurodollar Advance of such Type until the end of the then applicable Interest
Period therefor, at which time such Eurodollar Advance shall be automatically
converted into a Floating Rate Advance unless the Borrower shall have given the
Agent a Conversion/Continuation Notice requesting that, at the end of such
Interest Period, such Eurodollar Advance either continue as a Eurodollar Advance
of such Type for the same or another Interest Period or be converted into an
Advance of another Type. Subject to the terms of SECTION 2.6, the Borrower may
elect from time to time to convert all or any part of an Advance of any Type
into any other Type or Types of Advances; provided that any conversion of any
Eurodollar Advance shall be made on, and only on, the last day of the Interest
Period applicable thereto. The Borrower shall give the Agent irrevocable notice
in the form of EXHIBIT I hereto (a "CONVERSION/CONTINUATION NOTICE") of each
conversion of an Advance or continuation of a Eurodollar Advance not later than
10:00 a.m. (Chicago time) (i) in the case of a conversion into a Floating Rate
Advance on the date of such conversion and (ii) in the case of a conversion into
or continuation of a Eurodollar Advance, at least three Business Days before the
date of such conversion or continuation, specifying:

                  (a) the requested date, which shall be a Business Day, of such
         conversion or continuation;

                  (b) the aggregate amount and Type of the Advance which is to
         be converted or continued; and

                  (c) the amount and Type(s) of Advance(s) into which such
         Advance is to be converted or continued and, in the case of a
         conversion into or continuation of a Eurodollar Advance, the duration
         of the Interest Period applicable thereto.

The Borrower shall select Interest Periods so that it is not necessary to repay
any portion of a Eurodollar Advance prior to the last day of the applicable
Interest Period in order to make a mandatory repayment required pursuant to
SECTION 2.2.

                  2.8. PAYMENT OF INTEREST ON ADVANCES; CHANGES IN INTEREST
RATE. (a) Interest accrued on each Floating Rate Advance shall be payable on the
last Business Day of each calendar month, on the Revolving Credit Termination
Date, and on the earliest of the Facility Termination Date, the date of the
reduction to zero of the Aggregate Commitment pursuant to SECTION 2.9 and the
date of the acceleration of the Obligations pursuant to SECTION 8.1. Interest
accrued on each Eurodollar Advance shall be payable on the last day of its
applicable Interest Period, on any date on which such Eurodollar Advance is
prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued
on each Eurodollar Advance having an Interest Period longer than three months
shall also be payable on the last day of each three-month interval during such
Interest Period. Interest on Floating Rate Advances shall be calculated for
actual days elapsed on the basis of a 365/366-day year. Interest on Eurodollar
Advances shall be calculated for actual days elapsed on the basis of a 360-day
year. Interest shall be payable for the day a Advance is made but not for the
day of any payment on the amount paid if payment is received prior to noon
(local time) at the place of payment. If any payment of principal of or interest
on a Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

                  (b) Each Floating Rate Advance shall bear interest on the
outstanding principal amount thereof, for each day from and including the date
such Advance is made or is converted from a Eurodollar Advance into a Floating
Rate Advance pursuant to SECTION 2.7(b) to but excluding the date it becomes due
or is converted into a Eurodollar Advance pursuant to SECTION 2.7(b), at a rate
per annum equal to the Floating Rate for such day. Changes in the rate of
interest on each Advance maintained as a Floating Rate Advance will take effect
simultaneously with each change in the Alternate Base Rate. Each Eurodollar
Advance shall bear interest from and 



                                       10
<PAGE>   16


including the first day of the Interest Period applicable thereto to (but not
including) the last day of such Interest Period at the Eurodollar Rate
determined as applicable to such Eurodollar Advance. No Interest Period may end
after the Facility Termination Date.

                  2.9. COMMITMENT FEE; REDUCTIONS IN AGGREGATE COMMITMENT. (a)
The Borrower agrees to pay to the Agent for the account of each Lender a
commitment fee at a rate per annum equal to the Applicable Commitment Fee Rate
in effect from time to time on the daily unused portion of such Lender's
Commitment from the date hereof to but excluding the earliest of the Revolving
Credit Termination Date, the date of the reduction to zero of the Aggregate
Commitment pursuant to SECTION 2.9(b) and the date of the termination of the
Aggregate Commitment pursuant to SECTION 8.1. Such commitment fees shall be
payable in arrears on the last Business Day of each March, June, September and
December, and on the earliest of the Revolving Credit Termination Date, the date
of the reduction to zero of the Aggregate Commitment pursuant to SECTION 2.9(b)
and the date of the termination of the Aggregate Commitment pursuant to SECTION
8.1. Commitment fees shall be calculated for actual days elapsed on the basis of
a 360-day year.

                  (b) The Borrower may permanently reduce the Aggregate
Commitment in whole, or in part ratably among the Lenders in integral multiples
of not less than $20,000,000 or an integral multiple of $5,000,000 in excess
thereof, upon at least three Business Days' written notice to the Agent, which
notice shall specify the amount of any such reduction; PROVIDED, HOWEVER, that
the amount of the Aggregate Commitment may not be reduced below the sum of the
aggregate principal amount of the outstanding Advances.

                  2.10. RATES APPLICABLE AFTER DEFAULT. Notwithstanding
anything to the contrary contained in SECTION 2.8, during the continuance of a
Default or Unmatured Default no Advance may be made as, converted into or
continued as a Eurodollar Advance. During the continuance of a Default pursuant
to SECTION 7.2 and, if the Required Banks so elect, during the continuance of
any other Default, (a) each Eurodollar Advance, until paid in full or converted
to a Floating Rate Advance, shall bear interest at the Eurodollar Rate then
applicable to such Advance plus 3% per annum, and (b) each Floating Rate Advance
shall bear interest until paid in full at a rate per annum equal to the Floating
Rate plus 3% per annum.

                  2.11. METHOD OF PAYMENT. All payments of the Obligations
hereunder shall be made, without setoff, deduction, or counterclaim, in
immediately available funds to the Agent at the Agent's address specified
pursuant to ARTICLE XIII, or at any other Lending Installation of the Agent
specified in writing by the Agent to the Borrower, by 12:00 noon (local time) on
the date when due and shall be remitted by the Agent to the Lenders according to
their respective interests therein. Each payment delivered to the Agent for the
account of any Lender shall be delivered promptly by the Agent to such Lender in
the same type of funds that the Agent received at its address specified pursuant
to ARTICLE XIII or at any Lending Installation specified in a notice received by
the Agent from such Lender. The Agent is hereby authorized, but is not
obligated, to charge the accounts of the Borrower maintained with First Chicago
into which proceeds of Advances are remitted pursuant to SECTION 2.6 for each
payment of interest and fees as it becomes due hereunder and for each payment of
principal, in accordance with the applicable Prepayment Notice or when otherwise
due and payable in accordance with the terms hereof.

                  2.12. NOTES; TELEPHONIC NOTICES. Each Lender is hereby
authorized to record the date and principal amount of each of its Loans and the
date and amount of each repayment on the schedule attached to its Note;
PROVIDED, HOWEVER, that the failure to so record shall not affect the Borrower's
obligations under such Note. The Borrower hereby authorizes the Lenders and the
Agent to extend, convert or continue Advances and effect selections of Types of
Advances based on telephonic notices made by any person or persons the Agent in
good faith believes to be acting on behalf of the Borrower. The Borrower agrees
to deliver promptly to the Agent a written confirmation, if such confirmation is
requested by the Agent or any Lender, of each telephonic notice, signed by an
Authorized Officer. If the written confirmation differs in any material respect
from the action taken by the Agent and the Lenders, the records of the Agent of
the relevant telephonic notice shall govern absent manifest error.

                  2.13. NOTIFICATION OF ADVANCES, INTEREST RATES, PREPAYMENTS
AND COMMITMENT REDUCTIONS. Promptly after receipt thereof, the Agent will
notify each Lender of the contents of each Aggregate Commitment reduction
notice, Borrowing Notice, Conversion/Continuation Notice, and Prepayment Notice
received by it hereunder. The Agent will notify each Lender of the interest rate
applicable to each Eurodollar Advance promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Alternate Base Rate.


                                       11
<PAGE>   17



                  2.14. LENDING INSTALLATIONS. Each Lender may book its Loans
at any one or more Lending Installations selected by such Lender and may change
any such Lending Installation from time to time. All terms of this Agreement
shall apply to any such Lending Installation and the Notes shall be deemed held
by each Lender for the benefit of such Lending Installation. Each Lender may, by
written or telex notice to the Agent and the Borrower, designate a Lending
Installation through which Loans will be made by it and for whose account Loan
payments are to be made.

                  2.15. NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Borrower
or a Lender, as the case may be, notifies the Agent prior to the date on which
it is scheduled to make payment to the Agent of (a) in the case of a Lender, the
proceeds of a Loan or (b) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. If
such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (a) in the case of repayment by a Lender,
the Federal Funds Effective Rate for such day or (b) in the case of repayment by
the Borrower, the interest rate applicable to the relevant Loan.

                  2.16. WITHHOLDING TAX EXEMPTION. At least five Business Days
prior to the first date on which interest or fees are payable hereunder for the
account of any Lender, each Lender that is not incorporated under the laws of
the United States of America, or a state thereof, agrees that it will deliver to
each of the Borrower and the Agent two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224, certifying in either case that such
Lender is entitled to receive payments under this Agreement and the Notes
without deduction or withholding of any United States federal income taxes. Each
Lender which so delivers a Form 1001 or 4224 further undertakes to deliver to
each of the Borrower and the Agent two additional copies of such form (or any
successor form or related form as may from time to time be required under
applicable law) on or before the date that such form expires (currently, three
successive calendar years for Form 1001 and one calendar year for Form 4224) or
becomes obsolete or after the occurrence of any event requiring a change in the
most recent forms so delivered by it, and such amendments thereto or extensions
or renewals thereof as may be reasonably requested by the Borrower or the Agent,
in each case certifying that such Lender is entitled to receive payments under
this Agreement and the Notes without deduction or withholding of any United
States federal income taxes, unless an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any
such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Lender from duly completing and
delivering any such form with respect to it and such Lender advises the Borrower
and the Agent that it is not capable of receiving payments without any deduction
or withholding of United States federal income tax.

                                   ARTICLE III
                             CHANGE IN CIRCUMSTANCES

                  3.1. YIELD PROTECTION. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law), or any interpretation thereof, or the compliance
by any Lender therewith,

                  (a) subjects any Lender or any applicable Lending Installation
         to any tax, duty, charge or withholding on or from payments due from
         the Borrower (excluding federal taxation of the overall net income of
         any Lender), or changes the basis of taxation of payments to any Lender
         in respect of its Loans or other amounts due it hereunder, or

                  (b) imposes or increases or deems applicable any reserve,
         assessment, insurance charge, special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by, any Lender or any applicable Lending Installation (other
         than reserves and assessments taken into account in determining the
         interest rate applicable to Eurodollar Advances), or

                  (c) imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Lending Installation
         of making, funding or maintaining Loans or reduces any amount
         receivable by any Lender or any applicable Lending Installation in


                                       12
<PAGE>   18



         connection with Loans, or requires any Lender or any applicable Lending
         Installation to make any payment calculated by reference to the amount
         of Loans held, or interest received, by it by an amount deemed material
         by such Lender,

then, within 15 days of demand by such Lender, the Borrower shall pay such
Lender that portion of such increased expense incurred or reduction in an amount
received which such Lender determines is attributable to making, funding and
maintaining its Loans and its Commitment.

                  3.2. CHANGES IN CAPITAL ADEQUACY REGULATIONS. If a Lender
determines that the amount of capital required or expected to be maintained by
such Lender, any Lending Installation of such Lender or any corporation
controlling such Lender is increased as a result of a Change (as defined below
in this SECTION 3.2), then, within 15 days of demand by such Lender, the
Borrower shall pay such Lender the amount necessary to compensate for any
shortfall in the rate of return on the portion of such increased capital which
such Lender determines is attributable to this Agreement, its Loans, or its
obligation to make Loans hereunder (after taking into account such Lender's or
such controlling corporation's policies as to capital adequacy). "CHANGE" means
(a) any change after the date of this Agreement in the Risk-Based Capital
Guidelines (as defined below in this SECTION 3.2) or (b) any adoption of or
change in any other law, governmental or quasi-governmental rule, regulation,
policy, guideline, interpretation, or directive (whether or not having the force
of law) after the date of this Agreement which affects the amount of capital
required or expected to be maintained by any Lender or any Lending Installation
or any corporation controlling any Lender. "RISK-BASED CAPITAL GUIDELINES" means
(a) the risk-based capital guidelines in effect in the United States on the date
of this Agreement, including transition rules, and (b) the corresponding capital
regulations promulgated by regulatory authorities outside the United States
implementing the July 1988 report of the Basle Committee on Banking Regulation
and Supervisory Practices Entitled "International Convergence of Capital
Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.

                  3.3. AVAILABILITY OF TYPES OF ADVANCES. If any Lender
determines that maintenance of its Eurodollar Loans at a suitable Lending
Installation would violate any applicable law, rule, regulation, or directive,
whether or not having the force of law, or if the Required Lenders determine
that (a) deposits of a type and maturity appropriate to match fund Eurodollar
Advances are not available or (b) the interest rate applicable to a Type of
Advance does not accurately reflect the cost of making or maintaining such
Advance, then the Agent shall suspend the availability of the affected Type of
Advance and require any Eurodollar Advances of the affected Type to be prepaid.

                  3.4. FUNDING INDEMNIFICATION. If any payment of a Eurodollar
Advance occurs on a date which is not the last day of the applicable Interest
Period in the case of a Eurodollar Advance, whether because of acceleration,
prepayment or otherwise, or a Eurodollar Advance is not made (whether by
borrowing, continuation or conversion) on the date specified by the Borrower for
any reason other than default by the Lenders, or an optional prepayment, notice
of which has been given in accordance with SECTION 2.5, is not made on the date
specified therefor in such notice, the Borrower will indemnify each Lender for
any loss or cost incurred by it resulting therefrom, including, without
limitation, any loss or cost in liquidating or employing deposits acquired to
fund or maintain such Eurodollar Advance.

                  3.5. MITIGATION; LENDER STATEMENTS; SURVIVAL OF INDEMNITY .
(a) To the extent reasonably possible, each Lender shall designate an alternate
Lending Installation with respect to its Eurodollar Loans to reduce any
liability of the Borrower to such Lender under SECTIONS 3.1 and 3.2 or to avoid
the unavailability of a Type of Advance under SECTION 3.3, so long as such
designation is not disadvantageous to such Lender. If the obligation of the
Lenders to make Eurodollar Advances has been suspended pursuant to SECTION 3.3
as a consequence of a determination by any Lender that maintenance of its
Eurodollar Loans at a suitable Lending Installation would violate any applicable
law or any Lender has demanded compensation under SECTION 3.1 or 3.2, the
Borrower may elect (i) subject to SECTION 3.4, to prepay any outstanding
Advances to the extent necessary to mitigate its liability under SECTION 3.1 or
3.2, (ii) to terminate the applicable Lender's Commitment hereunder or (iii) to
require the applicable Lender to assign its outstanding Loans and Commitment
hereunder to another financial institution designated by the Borrower and
reasonably acceptable to the Agent. The obligation of a Lender to assign its
rights and obligations hereunder or terminate its Commitment hereunder as
contemplated by this SECTION 3.5(a) is subject to the requirements that (x) all
amounts owing to that Lender under the Loan Documents are paid in full upon the
completion of such assignment or prior to such termination and (y) any
assignment is effected in accordance with the terms of SECTION 12.3 and 



                                       13

on terms otherwise satisfactory to that Lender (it being understood that the
Borrower shall pay the processing fee payable to the Agent pursuant to SECTION
12.3.2 in connection with any such assignment).

                  (b) Each Lender shall deliver a written statement of such
Lender as to the amount due, if any, under SECTION 3.1, 3.2 or 3.4. Such written
statement shall set forth in reasonable detail the calculations upon which such
Lender determined such amount and shall be final, conclusive and binding on the
Borrower in the absence of manifest error. Determination of amounts payable
under such Sections in connection with a Eurodollar Loan shall be calculated as
though each Lender funded such Loan through the purchase of a deposit of the
type and maturity corresponding to the deposit used as a reference in
determining the interest rate applicable to such Loan, whether in fact that is
the case or not. Unless otherwise provided herein, the amount specified in the
written statement shall be payable on demand after receipt by the Borrower of
the written statement. The obligations of the Borrower under SECTIONS 3.1, 3.2
and 3.4 shall survive payment of the Obligations and termination of this
Agreement.

                              CONDITIONS PRECEDENT

                   4.1. EFFECTIVENESS; INITIAL ADVANCE. This Agreement shall

         any are deemed necessary by counsel for any Lender) authorizing the
         execution of the relevant Loan Documents;

                  (c) incumbency certificates, executed by the Secretary or
         Assistant Secretary or other appropriate officer or director of the
         Borrower, which shall identify by name and title and bear the signature
         of the officers of the Borrower authorized to sign the relevant Loan
         Documents and to make borrowings hereunder, as applicable, upon which
         certificate the Agent and the Lenders shall be entitled to rely until

                  (d) a certificate, signed by the Chief Financial Officer of
         the Borrower, stating that, to the best of his knowledge after due

By January 22, 1999, the Borrower shall deliver to the Agent a certificate of
the Secretary or Assistant Secretary of each Initial Guarantor certifying
resolutions of such Initial Guarantor's board of directors authorizing the
execution, delivery and performance of the Guaranty.

                  4.2. EACH ADVANCE. No Lender shall be required to make any
Loan hereunder, unless on the applicable Borrowing Date:

                  (a) there exists no Default or Unmatured Default;

                  (b) the representations and warranties contained in ARTICLE V
         are true and correct as of such Borrowing Date except to the extent any
         such representation or warranty is stated to relate solely to an
         earlier date, in which case such representation or warranty shall be
         true and correct on and as of such earlier date; and

                  (c) after giving effect to such Loan, the aggregate
         outstanding principal amount of all Advances does not exceed the
         Aggregate Commitment.

Each Borrowing Notice and each Conversion/Continuation Notice with respect to a
Loan shall constitute a representation and warranty by the Borrower that the
conditions contained in SECTIONS 4.2(a), (b) and (c) have been satisfied.


                                    ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

                  5. REPRESENTATIONS AND WARRANTIES. The Borrower represents
and warrants to the Lenders that:

                  5.1. CORPORATE EXISTENCE AND STANDING. The Borrower and each
         of its Subsidiaries is a corporation duly incorporated, validly
         existing and in good standing under the laws of its jurisdiction of
         incorporation and has all requisite authority to conduct its business
         in each jurisdiction in which its business is conducted, except to the
         extent that, in the case of any Subsidiary of the Borrower, the failure
         to be in good standing or authorized to conduct business in any
         jurisdiction could not, when taken together with all similar failures
         by such Subsidiary and each other Subsidiary, reasonably be expected to
         have a Material Adverse Effect.

                  5.2. AUTHORIZATION AND VALIDITY. The Borrower and each
         Guarantor has the corporate power and authority and legal right to
         execute and deliver the Loan Documents to which it is party and to
         perform its obligations thereunder. The execution and delivery by each
         of the Borrower and each Guarantor of the Loan Documents to which it is
         party and the performance of its obligations thereunder have been duly
         authorized by proper corporate proceedings, and each Loan Document to
         which the Borrower or any Guarantor is party constitutes the legal,
         valid and binding obligation of the Borrower or such Guarantor, as
         applicable, enforceable against the Borrower or such Guarantor, as
         applicable, in accordance with its terms, except as enforceability may
         be limited by bankruptcy, insolvency or similar laws affecting the
         enforcement of creditors' rights generally and general principles of
         equity, regardless of whether the application of such principles is
         considered in a proceeding in equity or at law.

                  5.3. NO CONFLICT; GOVERNMENT CONSENT. Neither the execution
         and delivery by each of the Borrower and each Guarantor of the Loan
         Documents to which it is party, nor the consummation of the
         transactions therein contemplated, nor compliance with the provisions
         thereof will violate any law, rule, regulation, order, writ, judgment,
         injunction, decree or award binding on the Borrower or any Subsidiary
         or the Borrower's or any Subsidiary's articles of incorporation or
         by-laws or comparable constitutive documents or the provisions of any
         indenture, instrument or agreement to which the Borrower or any
         Subsidiary is a party or is subject, or by which it, or its Property,
         is bound, or conflict with or constitute a default thereunder, or
         result in the creation or imposition of any Lien in, of or on the
         Property of the Borrower or any Subsidiary pursuant to the terms of any
         such indenture, instrument or agreement which violation, conflict or
         imposition could reasonably be expected to have a Material Adverse
         Effect. No order, consent, approval, license, authorization, or
         validation of, or filing, recording or registration with, or exemption
         by, any governmental or public body or authority, or any subdivision
         thereof, is required to authorize, or is required in connection with
         the execution, delivery and 



                                       15
<PAGE>   21


         performance of, or the legality, validity, binding effect or
         enforceability of, any of the Loan Documents.

                  5.4. FINANCIAL STATEMENTS. The December 31, 1997 and June 30,
         1998 consolidated financial statements of the Borrower and its
         Subsidiaries, heretofore delivered to the Lenders, were prepared in
         accordance with GAAP in effect on the dates such statements were
         prepared and fairly present the consolidated financial condition and
         operations of the Borrower and its Subsidiaries at the dates thereof
         and the consolidated results of their operations for the periods then
         ended, subject, in the case of the June 30, 1998 financial statements,
         to normal year-end adjustments and the absence of notes.

                  5.5. MATERIAL ADVERSE CHANGE. Since June 30, 1998, there has
         been no change in the business, Property, prospects, condition
         (financial or otherwise) or results of operations of the Borrower and
         its Subsidiaries which could reasonably be expected to have a Material
         Adverse Effect.

                  5.6. TAXES. All tax returns required to be filed by the
         Borrower or any of its Subsidiaries in any jurisdiction have, in fact,
         been filed, all such tax returns have been prepared in accordance with
         applicable laws, and all taxes, assessments, fees and other
         governmental charges upon the Borrower or any Subsidiary or upon any of
         their respective properties, income or franchises, which are shown on
         such returns have been paid except to the extent such tax payments are
         being contested in good faith by appropriate proceedings and with
         respect to which adequate reserves or other appropriate provisions are
         being maintained in accordance with Agreement Accounting Principles.
         For all taxable years ending on or before December 31, 1994, the United
         States Federal income tax liability of the Borrower and its
         Subsidiaries has been satisfied and either the period of limitations on
         assessment of additional United States Federal income tax has expired
         or the Borrower or the applicable Subsidiary has entered into an
         agreement with the United States Internal Revenue Service closing
         conclusively the total tax liability for the taxable year. Neither the
         Borrower nor any of its Subsidiaries knows of any proposed additional
         tax assessment against it or any of them for which adequate provision
         has not been made on its or their accounts, and no controversy in
         respect of additional income or other taxes due or claimed to be due to
         any Governmental Authority is pending or to the knowledge of the
         Borrower or its Subsidiaries threatened the outcome of which could
         reasonably be expected to have a Material Adverse Effect. The charges,
         accruals and reserves on the books of the Borrower and its Subsidiaries
         in respect of any taxes or other governmental charges are adequate.

                  5.7. LITIGATION AND CONTINGENT LIABILITIES. Except as set
         forth on SCHEDULE II hereto, there is no litigation, arbitration,
         governmental investigation, proceeding or inquiry pending or, to the
         knowledge of any of their officers, threatened against or affecting the
         Borrower or any Subsidiary of the Borrower which could reasonably be
         expected to have a Material Adverse Effect. Other than any liability
         incident to such litigation, arbitration or proceedings, to the
         knowledge of the Borrower's officers neither the Borrower nor any of
         its Subsidiaries has any material contingent liabilities not provided
         for or disclosed in the financial statements referred to in SECTION
         5.4.

                  5.8. SUBSIDIARIES. SCHEDULE II hereto, together with the most
         recent update, if any, delivered pursuant to SECTION 6.1(i), contains
         an accurate list of all of the Subsidiaries (except for inactive
         Subsidiaries with immaterial assets and liabilities) of the Borrower,
         setting forth their respective jurisdictions of incorporation and the
         percentage of their respective capital stock owned by the Borrower or
         its Subsidiaries. All of the issued and outstanding shares of capital
         stock of the Subsidiaries of the Borrower listed on SCHEDULE II hereto,
         together with the most recent update, if any, delivered pursuant to
         SECTION 6.1(i), have been duly authorized and issued and are fully paid
         and non-assessable.

                  5.9. ERISA. The Unfunded Liabilities of all Single Employer
         Plans do not in the aggregate exceed $10,000,000. Neither the Borrower
         nor any other member of the Controlled Group has incurred, or is
         reasonably expected to incur, any withdrawal liability to Multiemployer
         Plans in excess of $10,000,000 in the aggregate. Each Plan complies in
         all material respects with all applicable requirements of law and
         regulations, no Reportable Event has occurred with respect to any Plan,
         none of the Borrower or any other member of the Controlled Group has
         withdrawn from any Plan or initiated steps to do so, and no steps have
         been taken to reorganize or terminate any Plan.

                  5.10. ACCURACY OF INFORMATION. No written information,
         exhibit or report prepared and furnished by the Borrower or any
         Subsidiary to the Agent or to any Lender in connection with the
         negotiation of, or compliance with, the Loan Documents, taken as a
         whole, contained any material misstatement of fact or omitted to state
         a material fact or any fact necessary to make the statements contained
         therein not misleading.

                  5.11. REGULATION U. The Borrower and its Subsidiaries are in
         compliance with Regulation U.

                  5.12. MATERIAL AGREEMENTS. Neither the Borrower nor any of its
         Subsidiaries is in default in the performance, observance or
         fulfillment of any of the obligations, covenants or conditions
         contained in any agreement to which it is a party, which default could
         have a Material Adverse Effect.

                  5.13. COMPLIANCE WITH LAWS. The Borrower and its Subsidiaries
         have complied in all material respects with all applicable statutes,
         rules, regulations, orders and restrictions of any Governmental
         Authority having jurisdiction over the conduct of their respective
         businesses or the ownership of their respective Property except for
         such non-compliance as could not reasonably be expected to have a
         Material Adverse Effect. Neither the Borrower nor any of its
         Subsidiaries has received any notice to the effect that, or is
         otherwise aware that, its operations are not in material compliance
         with any of the requirements of applicable environmental, health and
         safety statutes and regulations of any Governmental Authority or the
         subject of any investigation by any Governmental Authority evaluating
         whether any remedial action is needed to respond to a release of any
         toxic or hazardous waste or substance into the environment, which
         non-compliance or remedial action could reasonably be expected to have
         a Material Adverse Effect.

                  5.14. OWNERSHIP OF PROPERTIES. Except as set forth on
         SCHEDULE II hereto, on the date of this Agreement, there are no Liens,
         other than those permitted by SECTION 6.16, on the Property and assets
         reflected as owned by the Borrower or any of its Subsidiaries in the
         financial statements delivered from time to time pursuant hereto.

                  5.15. INVESTMENT COMPANY ACT. Neither the Borrower nor any of
         its Subsidiaries is an "investment company" or a company "controlled"
         by an "investment company", within the meaning of the Investment
         Company Act of 1940, as amended.

                  5.16. PUBLIC UTILITY HOLDING COMPANY ACT. Neither the
         Borrower nor any of its Subsidiaries is a "holding company" or a
         "subsidiary company" of a "holding company", or an "affiliate" of a
         "holding company" or of a "subsidiary company" of a "holding company",
         within the meaning of the Public Utility Holding Company Act of 1935,
         as amended.

                  5.17. YEAR 2000. The Borrower and its Subsidiaries have made
         an assessment of the Year 2000 Issues and in good faith believe they
         have a realistic and achievable program for remediating the Year 2000
         Issues on a timely basis and a reasonable contingency plan to address
         any inability of computer applications in the computer systems of their
         material customers, suppliers and vendors to effectively handle data
         including dates on and after January 1, 2000. Based on such assessment
         and program, the Borrower and its Subsidiaries do not reasonably
         anticipate that Year 2000 Issues will have a Material Adverse Effect.

                                   ARTICLE VI
                                    COVENANTS

Required Lenders shall otherwise consent in writing:

         cause each of its Subsidiaries to maintain, a system of accounting
         established and administered in accordance with generally accepted
         accounting principles, and will furnish or cause to be furnished to the
         Lenders:

                  and based solely upon their audit of such financial
                  statements, nothing has come to their attention to cause them
                  to believe that there existed on the date of such statements
                  any Default or Unmatured Default under SECTIONS 6.17 or 6.18,
                  or, if in the opinion of such accountants, any Default or

         thereto.

         to remain duly incorporated, validly existing and in good standing as a
         domestic corporation in its jurisdiction of incorporation and maintain
         all requisite authority to conduct its business in each jurisdiction in

         Adverse Effect.

                  6.5. TAXES. The Borrower will, and will cause each of its
         Subsidiaries to, pay when due all taxes, assessments and governmental

         insurance companies insurance on all their Property in such amounts and

         insurance carried.

                  6.7. COMPLIANCE WITH LAWS. The Borrower will, and will cause

         laws (including, without limitation, all environmental laws), rules,

         their respective officers at such reasonable times and intervals during
         normal business hours, upon oral or written request of the Agent or any
         Lender at least three Business Days in advance so long as no Default or
         Unmatured Default shall have occurred and is continuing, or, if a
         Default or Unmatured Default has occurred and is continuing, upon the
         Agent's request. Such inspection rights are subject to reasonable
         limitations imposed by the Borrower and its Subsidiaries with respect

                  surviving corporation); and

                           (b) the Borrower may merge with or into any other
                  corporation if the Borrower shall be the continuing or

                  no Default or Unmatured Default shall have occurred and be
                  continuing or would result from such merger or consolidation

         of the Borrower's or such Subsidiary's business and upon fair and

         this SECTION 6.13 shall prohibit transactions between the Borrower and

         reasonably anticipated Material Adverse Effect as a result of Year 2000
         Issues or as

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

                  8.1. ACCELERATION. If any Default described in SECTION 7.6 or
7.7 occurs, the obligations of the Lenders to make Loans hereunder shall
automatically terminate and the Obligations shall immediately become due and
payable without any election or action on the part of the Agent or any Lender,
and without presentment, demand, protest or notice of any kind, all of which the
Borrower hereby expressly waives. If any other Default occurs, the Required
Lenders may (a) terminate or suspend the obligations of the Lenders to make
Loans or (b) declare the Obligations to be due and payable, whereupon the
Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which the 



                                       25
<PAGE>   31



Borrower hereby expressly waives, or (c) take the action described in both the
preceding clause (a) and the preceding clause (b).

                  If, within 30 days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
SECTION 7.6 or 7.7) and before any judgment or decree for the payment of the
Obligations due shall have been obtained or entered, the Required Lenders (in
their sole discretion) shall so direct, the Agent shall, by notice to the
Borrower, rescind and annul such acceleration and/or termination.

                  8.2. AMENDMENTS. Subject to the provisions of this ARTICLE
VIII, the Required Lenders (or the Agent with the consent in writing of the
Required Lenders) and the Borrower may enter into agreements supplemental hereto
for the purpose of adding or modifying any provisions to the Loan Documents or
changing in any manner the rights of the Lenders and the Borrower hereunder or
waiving any Default hereunder; PROVIDED, HOWEVER, that no such supplemental
agreement shall, without the consent of each Lender affected thereby:

                  (a) extend the maturity of any Loan or Note or forgive all or
         any portion of the principal amount thereof, any interest thereon or
         any fees or other amounts payable hereunder, or reduce the rate or
         extend the time of payment of interest, fees or other amounts payable
         hereunder;

                  (b) reduce the percentage specified in the definition of
         Required Lenders;

                  (c) reduce the amount or extend the payment date for the
         mandatory payments required under SECTION 2.2, or increase the amount
         of the Commitment of any Lender hereunder, or permit the Borrower to
         assign its rights or obligations under this Agreement;

                  (d) amend this SECTION 8.2; or

                  (e) release any Guarantor.

No amendment of any provision of this Agreement relating in any way to the Agent
shall be effective without the written consent of the Agent. The Agent may waive
payment of the fee required under SECTION 12.3.2 without obtaining the consent
of any other party to this Agreement.

                  8.3. PRESERVATION OF RIGHTS. No delay or omission of the
Lenders or any of them or the Agent to exercise any right under the Loan
Documents shall impair such right or be construed to be a waiver of any Default
or an acquiescence therein, and the making of a Loan notwithstanding the
existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to such Loan shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude any other or further exercise thereof or the exercise of any other
right, and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by (or with the consent of) the Lenders required pursuant to SECTION 8.2,
and then only to the extent specifically set forth in such writing. All remedies
contained in the Loan Documents or afforded by law shall be cumulative and all
shall be available to the Agent and the Lenders until the Obligations have been
paid in full.

                               GENERAL PROVISIONS

                  9.1. SURVIVAL OF REPRESENTATIONS. All representations and
warranties of the Borrower contained in this Agreement shall survive delivery of
the Notes and the making of the Loans herein contemplated.

                  9.2. GOVERNMENTAL REGULATION. Anything contained in this
Agreement to the contrary notwithstanding, no Lender shall be obligated to
extend credit to the Borrower in violation of any limitation or prohibition
provided by any applicable statute or regulation.

                  9.3. STAMP DUTIES. The Borrower shall pay and forthwith on
demand indemnify each of the Agent and each Lender against any liability it
incurs in respect of any stamp, 



                                       26

                  9.4. HEADINGS. Section headings in the Loan Documents are for
convenience of reference only and shall not govern the interpretation of any of
the provisions of the Loan Documents.

                  9.5. ENTIRE AGREEMENT; INDEPENDENCE OF COVENANTS. The Loan
Documents and the letter agreement among the Agent, First Chicago Capital
Markets, Inc. and the Borrower dated November 2, 1998 embody the entire
agreement and understanding among the Borrower, the Agent and the Lenders and
supersede all prior agreements and understandings among the Borrower, the Agent
and the Lenders relating to the subject matter thereof. Except as otherwise
expressly provided herein, no provision of this Agreement shall be construed as
waiving, negating or otherwise qualifying any restriction, limitation or other
condition imposed by any other provision of this Agreement.

                  9.6. SEVERAL OBLIGATIONS; BENEFITS OF THIS AGREEMENT. The
respective obligations of the Lenders hereunder are several and not joint and no
Lender shall be the partner or agent of any other (except to the extent to which
the Agent is authorized to act as such). The failure of any Lender to perform
any of its obligations hereunder shall not relieve any other Lender from any of
its obligations hereunder. This Agreement shall not be construed so as to confer
any right or benefit upon any Person other than the parties to this Agreement
(and their Affiliates and respective directors, officers and employees with
respect to SECTION 9.7) and their respective successors and assigns.

                  9.7. EXPENSES; INDEMNIFICATION. The Borrower shall reimburse
the Agent for any reasonable costs, internal charges and out-of-pocket expenses
(including reasonable attorneys' fees and time charges of attorneys for the
Agent, which attorneys may be employees of the Agent) paid or incurred by the
Agent in connection with the preparation, negotiation, execution, delivery,
review, amendment, modification, and administration of the Loan Documents. The
Borrower also agrees to reimburse the Agent and the Lenders for any reasonable
costs, internal charges and out-of-pocket expenses (including reasonable
attorneys' fees and time charges of attorneys for the Agent and the Lenders,
which attorneys may be employees of the Agent or the Lenders) paid or incurred
by the Agent or any Lender in connection with the collection and enforcement of
the Loan Documents. The Borrower further agrees to indemnify the Agent, each
Lender and their respective Affiliates, and such entities' respective directors,
officers and employees (each an "Indemnitee") against all losses, claims,
damages, penalties, judgments, liabilities and expenses (including, without
limitation, all reasonable expenses of litigation or preparation therefor
whether or not the Agent or any Lender is a party thereto) which any of them may
pay or incur arising out of or relating to this Agreement, the other Loan
Documents, the transactions contemplated hereby or the direct or indirect
application or proposed application of the proceeds of any Loan hereunder except
to the extent that such losses, claims, damages, penalties, judgments,
liabilities and expenses are found in a final judgment by a court of competent
jurisdiction to have arisen solely from the Gross Negligence or willful
misconduct of such Indemnitee. The obligations of the Borrower under this
Section shall survive the termination of this Agreement.

                  9.8. NUMBERS OF DOCUMENTS. All statements, notices, closing
documents, and requests hereunder shall be furnished to the Agent with
sufficient counterparts so that the Agent may furnish one to each of the
Lenders.

                  9.9. ACCOUNTING. Except as provided to the contrary herein,
all accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles; PROVIDED, HOWEVER, that to the extent that any change in GAAP shall
alter the result of any financial covenant or test or any other accounting
determination to be computed or made hereunder, the Borrower agrees that such
covenant, test or other determination shall continue to be computed or made on
the basis of Agreement Accounting Principles as in effect prior to such change
in GAAP, unless the Required Lenders shall otherwise consent.

                  9.10. SEVERABILITY OF PROVISIONS. Any provision in any Loan
Document that is held to be inoperative, unenforceable, or invalid in any
jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or
invalid without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

                  9.11. NONLIABILITY OF LENDERS. The relationship between the
Borrower, on the one hand, and the Lenders and the Agent, on the other hand,
shall be solely that of borrower and lender. Neither the Agent nor any Lender
shall have any fiduciary responsibilities to the Borrower or any of its
Subsidiaries. Neither the Agent nor any Lender undertakes any responsibility to
the Borrower or any of its Subsidiaries to review or inform the Borrower or any
of its Subsidiaries of any matter in connection with any phase of the business
or operations of the Borrower or any of its Subsidiaries.

                  9.12. CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE
CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF
ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

                  9.13. CONSENT TO JURISDICTION. THE BORROWER HEREBY
IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES
FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION
IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM.
NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING
PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.

                  9.14. WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH
LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY
OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN
ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.

                  9.15. CONFIDENTIALITY. Each of the Agent and each Lender
agrees to hold any confidential information which it may receive from the
Borrower or any of its Subsidiaries pursuant to this Agreement in confidence,
except for disclosure (a) to other Lenders or their respective affiliates, (b)
to legal counsel, accountants, and other professional advisors to that Lender or
to a Transferee, (c) to regulatory officials and examiners, (d) to any Person as
requested pursuant to or as required by law, regulation, or legal process, (e)
to any Person in connection with any legal proceeding to which that Lender is a
party, and (f) permitted by SECTION 12.4; PROVIDED, HOWEVER, with respect to any
disclosure pursuant to SUBSECTIONS (d) and (e), the Agent or such Lender, as
applicable, uses its best efforts to notify the Borrower in writing immediately
upon its or their receipt of any demand for such disclosures except to the
extent such notice to the Borrower is prohibited by any law or regulatory
authority.


                                    ARTICLE X
                                    THE AGENT

                  10.1. APPOINTMENT. First Chicago is hereby appointed Agent
hereunder and under each other Loan Document, and each of the Lenders
irrevocably authorizes the Agent to act as the agent of such Lender. The Agent
agrees to act as such upon the express conditions contained in this ARTICLE X.
The Agent shall not have a fiduciary relationship in respect of the Borrower,
any Subsidiary of the Borrower or any Lender by reason of this Agreement.

                  10.2. POWERS. The Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the Agent by
the terms of each thereof, together with such powers as are reasonably
incidental thereto. The Agent shall have no implied duties to the Lenders, or
any obligation to the Lenders to take any action thereunder except any action
specifically provided by the Loan Documents to be taken by the Agent.

                  10.3. GENERAL IMMUNITY. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable to any or all of the
Borrower, any Subsidiary of the Borrower or the Lenders for any action taken or
omitted to be taken by it or them hereunder or under any 



                                       28
<PAGE>   34


other Loan Document or in connection herewith or therewith, except to the extent
that such action or inaction is found in a final judgment by a court of
competent jurisdiction to have arisen solely from the Gross Negligence or wilful
misconduct of such Person.

                  10.4. NO RESPONSIBILITY FOR LOANS, RECITALS, ETC. Neither the
Agent nor any of its directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into, or verify (a) any
statement, warranty or representation made in connection with any Loan Document
or any borrowing hereunder; (b) the performance or observance of any of the
covenants or agreements of any obligor under any Loan Document, including,
without limitation, any agreement by an obligor to furnish information directly
to each Lender; (c) the satisfaction of any condition specified in ARTICLE IV,
except receipt of items required to be delivered to the Agent; or (d) the
validity, effectiveness or genuineness of any Loan Document or any other
instrument or writing furnished in connection therewith. The Agent shall have no
duty to disclose to the Lenders information that is not required to be furnished
by the Borrower to the Agent at such time, but is voluntarily furnished by the
Borrower to the Agent (either in its capacity as Agent or in its individual
capacity).

                  10.5. ACTION ON INSTRUCTIONS OF LENDERS. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
and under any other Loan Document in accordance with written instructions signed
by the Required Lenders or, in the case of any act or failure to act calculated
to give rise to any of the events or circumstances described in clauses (a)
through (e) of SECTION 8.2, each affected Lender, and such instructions and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders and on all holders of Notes. The Agent shall be fully justified in
failing or refusing to take any action hereunder and under any other Loan
Document unless it shall first be indemnified to its satisfaction by the Lenders
pro rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action.

                  10.6. EMPLOYMENT OF AGENTS AND COUNSEL. The Agent may execute
any of its duties as Agent hereunder and under any other Loan Document by or
through employees, agents, and attorneys-in-fact and shall not be answerable to
the Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning all matters pertaining to the agency hereby created and its
duties hereunder and under any other Loan Document.

                  10.7. RELIANCE ON DOCUMENTS; COUNSEL. The Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
of legal matters, upon the opinion of counsel selected by the Agent, which
counsel may be employees of the Agent.

                  10.8. AGENT'S REIMBURSEMENT AND INDEMNIFICATION. The Lenders
agree to reimburse and indemnify the Agent ratably in proportion to their
respective Commitments (a) for any amounts not reimbursed by the Borrower for
which the Agent is entitled to reimbursement by the Borrower under the Loan
Documents, (b) for any amounts not reimbursed by the Borrower for any other
expenses incurred by the Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents and (c) for any amounts not reimbursed by the Borrower for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or
arising out of the Loan Documents or any other document delivered in connection
therewith or the transactions contemplated thereby, or the enforcement of any of
the terms thereof or of any such other documents, provided that no Lender shall
be liable for any of the foregoing to the extent they are determined in a final
judgment of a court of competent jurisdiction to have arisen solely from the
Gross Negligence or willful misconduct of the Agent. The obligations of the
Lenders under this SECTION 10.8 shall survive payment of the Obligations and
termination of this Agreement.

                  10.9. RIGHTS AS A LENDER. In the event the Agent is a Lender,
the Agent shall have the same rights and powers hereunder and under any other
Loan Document as any Lender and may exercise the same as though it were not the
Agent, and the term "Lender" or "Lenders" shall, at any time when the Agent is a
Lender, unless the context otherwise indicates, include the Agent in its
individual capacity. The Agent may accept deposits from, lend money to, and
generally engage in any kind of trust, debt, equity or other transaction, in
addition to those contemplated by 



                                       29
<PAGE>   35


this Agreement or any other Loan Document, with the Borrower or any of its
Subsidiaries in which the Borrower or any of its Subsidiaries is not restricted
hereby from engaging with any other Person. The Agent, in its individual
capacity, is not obligated to remain a Lender; PROVIDED, HOWEVER, that in the
event that the Agent ceases to be a Lender hereunder, the Required Lenders may
remove the Agent and appoint a successor Agent, if no Default has occurred and
is continuing, with the consent of the Borrower.

                  10.10. LENDER CREDIT DECISION. Each Lender acknowledges that
it has, independently and without reliance upon the Agent or any other Lender
and based on the financial statements prepared by the Borrower and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and the other Loan Documents.
Each Lender also acknowledges that it will, independently and without reliance
upon the Agent or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement and the other Loan
Documents.

                  10.11. SUCCESSOR AGENT. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower, such resignation
to be effective upon the appointment of a successor Agent or, if no successor
Agent has been appointed, 45 days after the resigning Agent gives notice of its
intention to resign. Upon any such resignation the Required Lenders shall have
the right to appoint, on behalf of the Borrower and the Lenders, a successor
Agent. If no successor Agent shall have been so appointed by the Required
Lenders within 30 days after the resigning Agent's giving notice of its
intention to resign, then the resigning Agent may appoint, on behalf of the
Borrower and the Lenders, a successor Agent. If the Agent has resigned and no
successor Agent has been appointed, the Lenders may perform all the duties of
the Agent hereunder and the Borrower shall make all payments in respect of the
Obligations to the applicable Lender and for all other purposes shall deal
directly with the Lenders. No successor Agent shall be deemed to be appointed
hereunder until such successor Agent has accepted the appointment and, if no
Default or Unmatured Default has occurred and is continuing, the Borrower has
consented to such appointment. Any such successor Agent shall be a commercial
bank having capital and retained earnings of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning Agent. Upon the
effectiveness of the resignation of the Agent, the resigning Agent shall be
discharged from its duties and obligations hereunder and under the Loan
Documents. After the effectiveness of the resignation of an Agent, the
provisions of this ARTICLE X shall continue in effect for the benefit of such
Agent in respect of any actions taken or omitted to be taken by it while it was
acting as the Agent hereunder and under the other Loan Documents.

                  10.12. AGENT'S FEE. The Borrower agrees to pay to the Agent,
for its own account, the fees agreed to by the Borrower and the Agent by
separate letter agreement, or as otherwise agreed from time to time.

                  10.13. CO-AGENTS, DOCUMENTATION AGENTS, ETC. Neither any of
the Lenders identified in this Agreement as a "Co-Agent" nor the
Co-Documentation Agents shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of such Lenders shall have
or be deemed to have a fiduciary relationship with any Lender. Each Lender
hereby makes the same acknowledgments with respect to such Lenders as it makes
with respect to the Agent in SECTION 10.10.

                                   ARTICLE XI
                            SETOFF; RATABLE PAYMENTS

                  11.1. SETOFF. In addition to, and without limitation of, any
rights of the Lenders under applicable law, if the Borrower becomes insolvent,
however evidenced, or any Default or Unmatured Default occurs, any and all
deposits (including all account balances, whether provisional or final and
whether or not collected or available) and any other Indebtedness at any time
held or owing by any Lender to or for the credit or account of the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part hereof, shall then be due.

                  11.2. RATABLE PAYMENTS. If any Lender, whether by setoff or
otherwise (other than pursuant to SECTION 3.5 and ARTICLE XII), has payment made
to it upon its Loans (other than payments received pursuant to SECTION 3.1, 3.2
or 3.4) in a greater proportion than that received 


                                       30
<PAGE>   36


by any other Lender, such Lender agrees, promptly upon demand, to purchase a
portion of the Loans held by the other Lenders so that after such purchase each
Lender will hold its ratable proportion of Loans. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Lender agrees, promptly upon demand, to
take such action necessary such that all Lenders share in the benefits of such
collateral ratably in proportion to their Loans. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.


                                   ARTICLE XII
                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

                  12.1. SUCCESSORS AND ASSIGNS. The terms and provisions of the
Loan Documents shall be binding upon and inure to the benefit of the Borrower,
the Agent and the Lenders and their respective successors and assigns, except
that (a) the Borrower shall not have the right to assign its rights or
obligations under the Loan Documents without the consent of all of the Lenders
and (b) any assignment by any Lender must be made in compliance with SECTION
12.3. Notwithstanding clause (b) of the preceding sentence, any Lender may at
any time, without the consent of the Borrower or the Agent, assign all or any
portion of its rights under this Agreement and its Notes to a Federal Reserve
Bank; provided, HOWEVER, that no such assignment shall release the transferor
Lender from its obligations hereunder. The Agent may treat the payee of any Note
as the owner thereof for all purposes hereof unless and until such payee
complies with SECTION 12.3 in the case of an assignment thereof or, in the case
of any other transfer, a written notice of the transfer is filed with the Agent.
Any assignee or transferee of a Note agrees by acceptance thereof to be bound by
all the terms and provisions of the Loan Documents. Any request, authority or
consent of any Person, who at the time of making such request or giving such
authority or consent is the holder of any Note, shall be conclusive and binding
on any subsequent holder, transferee or assignee of such Note or of any Note or
Notes issued in exchange therefor.

                  12.2. PARTICIPATIONS .

                  12.2.1 PERMITTED PARTICIPANTS; EFFECT. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         (a) with contemporaneous notice to the Borrower, at any time sell to
         one or more banks or (b) with the consent of the Borrower, which
         consent shall not be unreasonably withheld, at any time sell to one or
         more other entities (each such bank or other entity being referred to
         herein as a "PARTICIPANT") participating interests in any Loan owing to
         such Lender, any Note held by such Lender, the Commitment of such
         Lender or any other interest of such Lender under the Loan Documents;
         PROVIDED, HOWEVER, that if a Participant is an Affiliate of such Lender
         or if a Default has occurred and is continuing, the consent of the
         Borrower shall not be required. In the event of any such sale by a
         Lender of participating interests to a Participant, such Lender's
         obligations under the Loan Documents shall remain unchanged, such
         Lender shall remain solely responsible to the other parties hereto for
         the performance of such obligations, such Lender shall remain the
         holder of any such Note for all purposes under the Loan Documents, all
         amounts payable by the Borrower under this Agreement shall be
         determined as if such Lender had not sold such participating interests,
         and the Borrower and the Agent shall continue to deal solely and
         directly with such Lender in connection with such Lender's rights and
         obligations under the Loan Documents. The participation agreement
         effecting the sale of any participating interest shall contain a
         representation by the Participant to the effect that none of the
         consideration used to make the purchase of the participating interest
         in the Commitment and Loans under such participation agreement are
         "plan assets" as defined under ERISA and that the rights and interests
         of the Participant in and under the Loan Documents will not be "plan
         assets" under ERISA.

                  12.2.2. VOTING RIGHTS. Each Lender shall retain the sole
         right to approve, without the consent of any Participant, any
         amendment, modification or waiver of any provision of the Loan
         Documents other than any amendment, modification or waiver with respect
         to any Loan or Commitment in which such Participant has an interest
         which forgives principal, interest or fees or reduces the interest rate
         or fees payable with respect to any such Loan or Commitment, postpones
         any date fixed for any regularly-scheduled payment of principal of, or
         interest or fees on, any such Loan or Commitment, or releases any
         guarantor of any such Loan.



                                       31
<PAGE>   37


                  12.2.3. BENEFIT OF SETOFF. The Borrower agrees that to the
         extent permitted by applicable law each Participant shall be deemed to
         have the right of setoff provided in SECTION 11.1 in respect of its
         participating interest in amounts owing under the Loan Documents to the
         same extent as if the amount of its participating interest were owing
         directly to it as a Lender under the Loan Documents, provided that each
         Lender shall retain the right of setoff provided in SECTION 11.1 with
         respect to the amount of participating interests sold to each
         Participant. The Lenders agree to share with each Participant, and each
         Participant shall be deemed to agree, by exercising the right of setoff
         provided in SECTION 11.1, to share with each Lender, any amount
         received pursuant to the exercise of its right of setoff, such amounts
         to be shared in accordance with SECTION 11.2 as if each Participant
         were a Lender.

                  12.3. ASSIGNMENTS.

                  12.3.1. PERMITTED ASSIGNMENTS. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time assign to one or more banks or other entities
         ("PURCHASERS") all or any part of its Commitment and outstanding Loans,
         together with its rights and obligations under the Loan Documents with
         respect thereto; PROVIDED, HOWEVER, that (a) each such assignment shall
         be of a constant, and not a varying, percentage of all of the assigning
         Lender's rights and obligations so assigned; (b) the amount of the
         Commitment of the assigning Lender being assigned pursuant to each such
         assignment (determined as of the date of such assignment) may be in the
         amount of such Lender's entire Commitment but otherwise shall not be
         less than $10,000,000 or an integral multiple of $1,000,000 in excess
         of that amount; and (c) notwithstanding the foregoing clause (b), (i)
         if the assignment is made to a Lender, the amount of the Commitment
         assigned shall not be less than $1,000,000 or an integral multiple
         thereof and (ii) if the assignment is made pursuant to SECTION 3.5, the
         Commitment assigned may be in the amount of the relevant Lender's
         entire remaining Commitment. Such assignment shall be substantially in
         the form of EXHIBIT D hereto or in such other form as may be agreed to
         by the parties thereto. The consent of the Borrower and the Agent shall
         be required prior to an assignment becoming effective with respect to a
         Purchaser which is not a Lender; PROVIDED, HOWEVER, that if a Default
         has occurred and is continuing, the consent of the Borrower shall not
         be required. Such consents shall not be unreasonably withheld.

                  12.3.2. EFFECT; EFFECTIVE DATE. Upon the later of (i) two
         Business Days (or such shorter period agreed to by the Agent) after (a)
         delivery to the Agent of a notice of assignment, substantially in the
         form attached to EXHIBIT D hereto (a "NOTICE OF ASSIGNMENT"), together
         with any consents required by SECTION 12.3.1, and (b) payment of a
         $3,500 fee to the Agent for processing such assignment, and (ii) the
         date certain specified in such Notice of Assignment, such assignment
         shall become effective. The Notice of Assignment shall contain a
         representation by the Purchaser to the effect that none of the
         consideration used to make the purchase of the Commitment and Loans
         under the applicable assignment agreement are "plan assets" as defined
         under ERISA and that the rights and interests of the Purchaser in and
         under the Loan Documents will not be "plan assets" under ERISA. On and
         after the effective date of such assignment, such Purchaser shall for
         all purposes be a Lender party to this Agreement and any other Loan
         Document executed by the Lenders and shall have all the rights and
         obligations of a Lender under the Loan Documents, to the same extent as
         if it were an original party hereto and thereto, and no further consent
         or action by the Borrower, the Lenders or the Agent shall be required
         to release the transferor Lender with respect to the percentage of the
         Aggregate Commitment and Loans assigned to such Purchaser. Upon the
         consummation of any assignment to a Purchaser pursuant to this SECTION
         12.3.2, the transferor Lender, the Agent, and the Borrower shall make
         appropriate arrangements so that replacement Notes are issued to such
         transferor Lender and new Notes or, as appropriate, replacement Notes,
         are issued to such Purchaser, in each case in principal amounts
         reflecting its Commitment, as adjusted pursuant to such assignment.

                  12.4. DISSEMINATION OF INFORMATION. The Borrower authorizes
each Lender to disclose to any Participant or Purchaser or any other Person
acquiring an interest in the Loan Documents by operation of law (each a
"TRANSFEREE") and any prospective Transferee any and all information in such
Lender's possession concerning the creditworthiness of the Borrower and its
Subsidiaries; provided that each Transferee and prospective Transferee agrees to
be bound by SECTION 9.15.

                  12.5. TAX TREATMENT. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of SECTION 2.16.


                                  ARTICLE XIII
                                    NOTICES

                  13.1. GIVING NOTICE. Except as otherwise permitted by SECTION
2.12 with respect to Borrowing Notices, all notices and other communications
provided to any party hereto under this Agreement or any other Loan Document
shall be in writing or by telex or by facsimile and addressed or delivered to
such party at its address set forth below its signature hereto or at such other
address as may be designated by such party in a notice to the other parties. Any
notice, if mailed and properly addressed with postage prepaid, shall be deemed
given when received; any notice, if transmitted by telex or facsimile, shall be
deemed given when transmitted (answerback confirmed in the case of telexes).

                  13.2. CHANGE OF ADDRESS. The Borrower, the Agent and any
Lender may each change the address for service of notice upon it by a notice in
writing to the other parties hereto.


                                   ARTICLE XIV
                                  COUNTERPARTS

                  This Agreement may be executed in any number of counterparts,
all of which taken together shall constitute one agreement, and any of the
parties hereto may execute this Agreement by signing any such counterpart.
Subject to SECTION 4.1, this Agreement shall be effective when it has been
executed by the Borrower, the Agent and the Lenders and each party has notified
the Agent by telex or telephone, that it has taken such action.

         For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

         "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating is Baa1 or better or the Borrower's S&P Rating is BBB+ or better.

         "Level II Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status and (ii) the Borrower's Moody's Rating is
Baa2 or better or the Borrower's S&P Rating is BBB or better.

         "Level III Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status or Level II Status and (ii) the
Borrower's Moody's Rating is Baa3 or better or the Borrower's S&P Rating is BBB-
or better.

         "Level IV Status" exists at any date if, on such date (i) the Borrower
has not qualified for Level I Status, Level II Status or Level III Status and
(ii) the Borrower's Moody's Rating is Ba1 or better or the Borrower's S&P Rating
is BB+ or better.

         "Level V Status" exists at any date if, on such date, the Borrower has
not qualified for Level I Status, Level II Status, Level III Status, or Level IV
Status.

         "Moody's Rating" means, at any time, the rating issued by Moody's
Investors Service, Inc. and then in effect with respect to the Borrower's senior
unsecured long-term debt securities without third-party credit enhancement.

         "S&P Rating" means, at any time, the rating issued by Standard & Poor's
Rating Services, a division of The McGraw-Hill Companies, Inc. and then in
effect with respect to the Borrower's senior unsecured long-term debt securities
without third-party credit enhancement.

         "Status" means either Level I Status, Level II Status, Level III
Status, Level IV Status or Level V Status.

         The Applicable Margin and Applicable Commitment Fee Rate shall be
determined in accordance with the foregoing table based on the Borrower's Status
as determined from its then-current Moody's and S&P Ratings. The credit rating
in effect on any date for the purposes of this Schedule is that in effect at the
close of business on such date. If at any time the Borrower has no Moody's
Rating or no S&P Rating, Level V Status shall exist, PROVIDED that if either S&P
or Moody's shall no longer provide debt ratings for companies in the Borrower's
industry generally, the Borrower may substitute for either such rating
organization another nationally recognized statistical rating organization, the
corresponding ratings of which shall be used to determine the Borrower's Status.
If the Borrower is split-rated and the ratings differential is one level, the
higher rating will apply. If the Borrower is split-rated and the ratings
differential is two levels, 


                                       50

the intermediate rating at the midpoint will apply. If the Borrower is
split-rated and the ratings differential is more than two levels, the rating
that is one level above the lowest rating will apply.

TO THE LENDERS AND THE AGENT
     REFERRED TO HEREIN

     REFERRED TO BELOW
C/O THE FIRST NATIONAL BANK OF CHICAGO
ONE FIRST NATIONAL PLAZA
CHICAGO, ILLINOIS 60670

LADIES AND GENTLEMEN:

         WE HAVE ACTED AS COUNSEL TO OMNICARE, INC. (THE "COMPANY") AND THE
ENTITIES LISTED ON SCHEDULE 1 HERETO (THE "GUARANTORS") IN CONNECTION WITH THE
364-DAY CREDIT AGREEMENT DATED AS OF DECEMBER 21, 1998 (THE "CREDIT AGREEMENT")
AMONG THE COMPANY, THE LENDERS LISTED ON THE SIGNATURE PAGES THEREOF (THE
"LENDERS") AND THE FIRST NATIONAL BANK OF CHICAGO, AS AGENT. THIS OPINION IS
FURNISHED TO YOU PURSUANT TO SECTION 4.1(e) OF THE CREDIT AGREEMENT. CAPITALIZED
TERMS USED IN THIS OPINION, AND NOT OTHERWISE DEFINED HEREIN, SHALL HAVE THE
MEANINGS ASCRIBED TO THEM IN THE CREDIT AGREEMENT.

         IN CONNECTION WITH THIS OPINION, WE HAVE REVIEWED THE CREDIT AGREEMENT
AND THE DOCUMENTS CONTEMPLATED BY THE CREDIT AGREEMENT TO BE EXECUTED AND
DELIVERED BY THE COMPANY AND THE GUARANTORS, INCLUDING THE NOTES AND THE
GUARANTY AND CONTRIBUTION AGREEMENT ENTERED INTO BY EACH OF THE GUARANTORS
(COLLECTIVELY, WITH THE CREDIT AGREEMENT, HEREIN REFERRED TO AS THE "LOAN
DOCUMENTS"). THE COMPANY AND THE GUARANTORS ARE HEREINAFTER COLLECTIVELY
REFERRED TO AS THE "CORPORATIONS." IN ADDITION, WE HAVE MADE SUCH INVESTIGATIONS
OF LAW AS WE HAVE DEEMED APPROPRIATE AS A BASIS FOR THE OPINIONS EXPRESSED
BELOW.

         IN RENDERING SUCH OPINIONS WE HAVE ASSUMED (I) THE GENUINENESS OF ALL
SIGNATURES (OTHER THAN THOSE ON BEHALF OF EACH CORPORATION), (II) THE
AUTHENTICITY OF ALL DOCUMENTS SUBMITTED TO US AS ORIGINALS AND THE CONFORMITY TO
THE ORIGINALS OF ALL DOCUMENTS SUBMITTED TO US AS CERTIFIED OR PHOTOSTATIC
COPIES, (III) THE DUE ORGANIZATION AND VALID EXISTENCE OF EACH OF THE LENDERS
AND THE AGENT, AND THE DUE AUTHORIZATION, EXECUTION AND DELIVERY BY EACH OF THE
LENDERS AND THE AGENT, AND THE LEGAL RIGHT OF EACH OF THE LENDERS AND THE AGENT
TO PERFORM ITS OBLIGATIONS UNDER, THE LOAN DOCUMENTS TO WHICH EACH IS A PARTY
AND (IV) THE ACCURACY AS TO FACTUAL MATTERS OF THE REPRESENTATIONS AND
WARRANTIES CONTAINED IN OR MADE PURSUANT TO THE CREDIT AGREEMENT.

         THE OPINION EXPRESSED BELOW AS TO THE CHOICE OF ILLINOIS LAW IS SUBJECT
TO THE CONDITION THAT THE APPLICATION OF ILLINOIS LAW WOULD NOT BE CONTRARY TO
THE FUNDAMENTAL POLICY OF A JURISDICTION OTHER THAN THE STATE OF OHIO (THE LAWS
OF WHICH OTHER JURISDICTION WOULD BE THE APPLICABLE LAW BUT FOR THE CHOICE OF
THE LAWS OF THE STATE OF ILLINOIS) HAVING A GREATER MATERIAL INTEREST IN THE
ISSUE THAN THE STATE OF ILLINOIS.

         WE ARE MEMBERS OF THE BAR OF THE STATE OF OHIO, AND WE EXPRESS NO
OPINION AS TO MATTERS GOVERNED BY THE LAWS OF ANY JURISDICTION OTHER THAN THE
FEDERAL LAW OF THE UNITED STATES, THE LAWS OF THE STATE OF OHIO AND, AS TO THE
OPINION EXPRESSED IN NUMBERED PARAGRAPHS 1, 2 AND 3 BELOW, THE GENERAL
CORPORATION LAW OF THE STATE OF DELAWARE. THE OPINION IN NUMBERED PARAGRAPH 1
WITH RESPECT TO THE INCORPORATION OF ANY CORPORATION UNDER THE LAWS OF ANY
JURISDICTION OTHER THAN OHIO OR DELAWARE AND WITH RESPECT TO THE FOREIGN
CORPORATION QUALIFICATION OR LICENSING OF ANY CORPORATION UNDER ANY JURISDICTION
IS BASED SOLELY UPON OUR REVIEW OF GOOD STANDING OR FOREIGN QUALIFICATION (AS
APPROPRIATE) CERTIFICATES FROM THE NECESSARY JURISDICTIONS.

To the Lenders and the Agent
     referred to herein                                                  Page 2



         BASED UPON THE FOREGOING AND SUBJECT TO THE FURTHER ASSUMPTIONS AND
QUALIFICATIONS SET FORTH HEREIN, WE ARE OF THE OPINION THAT:


         1. EACH OF THE CORPORATIONS IS A CORPORATION OR LIMITED LIABILITY
COMPANY, AS THE CASE MAY BE DULY ORGANIZED, VALIDLY EXISTING AND IN GOOD
STANDING UNDER THE LAWS OF ITS JURISDICTION OF INCORPORATION AND HAS ALL
REQUISITE CORPORATE POWER AND AUTHORITY TO OWN ITS PROPERTY AND ASSETS AND TO
CARRY ON ITS BUSINESS AS NOW BEING CONDUCTED. THE COMPANY AND, TO THE BEST OF
OUR KNOWLEDGE EACH OF THE GUARANTORS IS DULY QUALIFIED OR LICENSED TO DO
BUSINESS AS A FOREIGN CORPORATION, AND IS IN GOOD STANDING IN EACH JURISDICTION
WHEREIN BY REASON OF THE NATURE OF ITS ACTIVITIES AND/OR THE PROPERTIES OWNED OR
LEASED BY IT, SUCH QUALIFICATION OR LICENSING IS NECESSARY, EXCEPT WHERE THE
FAILURE TO BE SO QUALIFIED OR LICENSED DOES NOT HAVE A MATERIAL ADVERSE AFFECT
UPON ALL OF THE CORPORATIONS AND THEIR SUBSIDIARIES, TAKEN AS A WHOLE.

         2. THE EXECUTION, DELIVERY AND PERFORMANCE BY THE CORPORATIONS OF THE
LOAN DOCUMENTS TO WHICH THEY ARE PARTIES ARE WITHIN THEIR RESPECTIVE CORPORATE
POWERS, HAVE BEEN DULY AUTHORIZED AND, TO THE BEST OF OUR KNOWLEDGE, ARE NOT IN
CONTRAVENTION OF THE TERMS OF THEIR RESPECTIVE ARTICLES OR CERTIFICATES OF
INCORPORATION OR BY-LAWS.

         3. EACH OF THE LOAN DOCUMENTS TO WHICH THE CORPORATIONS ARE PARTIES
HAVE BEEN DULY EXECUTED AND DELIVERED BY THEM BY THEIR RESPECTIVE DULY
AUTHORIZED OFFICERS.

         4. ASSUMING THAT SUCH PROVISIONS ARE LEGAL, VALID, AND BINDING UNDER
THE LAWS OF ILLINOIS, THE PROVISIONS OF THE LOAN DOCUMENTS PROVIDING THAT SUCH
DOCUMENTS ARE GOVERNED BY ILLINOIS LAW SHOULD BE RESPECTED BY COURTS OF THE
STATE OF OHIO, AND, ACCORDINGLY, ILLINOIS LAW SHOULD BE APPLIED BY THE COURTS OF
THE STATE OF OHIO SO LONG AS THE PROVISIONS OF ILLINOIS LAW SOUGHT TO BE
ENFORCED ARE NOT INCONSISTENT WITH PUBLIC POLICY, AS SUCH TERM IS INTERPRETED
UNDER THE LAWS OF OHIO, IF ENFORCEMENT OF THE LOAN DOCUMENTS IS CONSIDERED BY
SUCH COURTS. IN THE EVENT COURTS IN THE STATE OF OHIO OR FEDERAL COURTS WERE TO
APPLY OHIO LAW AS THE GOVERNING LAW, EACH LOAN DOCUMENT WOULD CONSTITUTE THE
LEGAL, VALID AND BINDING OBLIGATION OF EACH CORPORATION WHICH IS A PARTY
THERETO, ENFORCEABLE AGAINST SUCH CORPORATION IN ACCORDANCE WITH ITS TERMS,
SUBJECT TO THE QUALIFICATIONS EXPRESSED BELOW.

         5. TO THE BEST OF OUR KNOWLEDGE, THE EXECUTION, DELIVERY AND
PERFORMANCE BY EACH CORPORATION OF THE LOAN DOCUMENTS TO WHICH IT IS A PARTY
WILL NOT (a) VIOLATE OR RESULT IN A BREACH OF THE PROVISIONS OF, OR CONSTITUTE A
DEFAULT UNDER, ANY CONTRACT TO WHICH EACH SUCH CORPORATION IS A PARTY, EXCEPT
FOR ANY SUCH BREACH OR DEFAULT WHICH IS NOT LIKELY TO RESULT IN ANY MATERIAL
ADVERTISE CHANGE IN THE BUSINESS, OPERATIONS, CONDITION (FINANCIAL OR OTHERWISE)
, PROPERTIES OR ASSETS OF ALL OF THE CORPORATIONS AND THEIR SUBSIDIARIES, TAKEN
AS A WHOLE, OR (b) CONFLICT WITH OR RESULT IN THE BREACH OF ANY COURT DECREE OR
ORDER OF ANY GOVERNMENTAL BODY BINDING UPON EACH SUCH CORPORATION.

         THE OPINIONS EXPRESSED HEREIN ARE SUBJECT TO THE FOLLOWING
QUALIFICATIONS:

         A. THE ENFORCEABILITY OF THE LOAN DOCUMENTS MAY BE LIMITED BY
APPLICABLE BANKRUPTCY, INSOLVENCY, REORGANIZATION, FRAUDULENT TRANSFER,
MORATORIUM, REARRANGEMENT, LIQUIDATION, CONSERVATORSHIP OR OTHER LAWS AFFECTING
CREDITORS, RIGHTS GENERALLY, INCLUDING COURT DECISIONS INTERPRETING SUCH LAWS,
STATUTES OF LIMITATIONS AND PERSONAL JURISDICTION.

         B. THE ENFORCEABILITY OF THE LOAN DOCUMENTS AND THE AVAILABILITY OF
SPECIFIC PERFORMANCE, INJUNCTIVE RELIEF, AND OTHER FORMS OF EQUITABLE RELIEF ARE
SUBJECT TO PRINCIPLES OF EQUITY (REGARDLESS OF WHETHER SUCH ENFORCEABILITY

IS CONSIDERED IN A PROCEEDING IN EQUITY OR AT LAW), COMMERCIAL REASONABLENESS
AND CONSCIONABILITY, UNDER WHICH A COURT MIGHT, AMONG OTHER THINGS., DECLINE TO
PERMIT ACCELERATION OF INDEBTEDNESS OR DEMAND FOR PAYMENT WITH RESPECT TO BREACH
OF A COVENANT DEEMED NOT MATERIAL BY THE COURT, OR REQUIRE THE LENDERS AND/OR
THE AGENT TO ACT WITH REASONABLENESS AND GOOD FAITH.

         C. CERTAIN RIGHTS OR REMEDIES UNDER THE LOAN DOCUMENTS MAY BE LIMITED
BY, OR UNAVAILABLE UNDER, THE LAWS OF THE STATE OF OHIO. HOWEVER, NONE OF SUCH
LIMITATIONS OR AVAILABILITY, SINGLY OR IN THE AGGREGATE, SHOULD MATERIALLY
INTERFERE WITH THE PRACTICAL REALIZATION OF THE LEGAL RIGHTS AND REMEDIES
PROVIDED FOR BY THE LOAN DOCUMENTS.

         D. NO OPINION IS EXPRESSED WITH RESPECT TO THE ENFORCEABILITY OF ANY
PROVISIONS OF THE LOAN DOCUMENTS THAT PURPORT TO REQUIRE PAYMENT OR
REIMBURSEMENT OF ATTORNEYS' FEES OR LITIGATION EXPENSES OF ANOTHER PARTY.

         E. WITH REGARD TO THE ENFORCEABILITY OF EACH GUARANTY AND CONTRIBUTION
AGREEMENT, WE HAVE ASSUMED, BUT EXPRESS NO OPINION AS TO, THE EXISTENCE OF
ADEQUATE AND SUFFICIENT CONSIDERATION TO THE APPLICABLE GUARANTOR AND
CO-OBLIGOR. NO OPINION IS EXPRESSED WITH RESPECT TO THE ENFORCEABILITY OF ANY
PROVISIONS OF THE LOAN DOCUMENTS THAT PURPORT TO REQUIRE, OR WOULD HAVE THE
EFFECT OF REQUIRING, ANY OF THE CORPORATIONS TO PAY, PURSUANT TO A GUARANTY OR
CONTRIBUTION AGREEMENT, ANY AMOUNT IN EXCESS OF ITS ALLOCABLE AMOUNT (AS DEFINED
IN THE CONTRIBUTION AGREEMENT) TO ANY OR ALL OF THE CREDITORS.

         F. NO OPINION IS EXPRESSED WITH RESPECT TO (I) SECTION 12.2 OF THE
CREDIT AGREEMENT INSOFAR AS IT PROVIDES THAT ANY ENTITY PURCHASING A
PARTICIPATION FROM A LENDER PURSUANT THERETO MAY EXERCISE SET-OFF OR SIMILAR
RIGHTS WITH RESPECT TO SUCH PARTICIPATION, (II) SECTION 11.1 OF THE CREDIT
AGREEMENT INSOFAR AS IT AUTHORIZES EACH LENDER TO SET OFF AND APPLY ANY DEPOSITS
AT ANY TIME HELD, AGAINST ANY OTHER INDEBTEDNESS AT ANY TIME OWING, BY SUCH
LENDER TO OR ON ACCOUNT OF THE COMPANY, AND (III) THE EFFECT OF THE LAW OF ANY
JURISDICTION OTHER THAN THE STATE OF OHIO WHEREIN ANY LENDER MAY BE LOCATED OR
WHEREIN ENFORCEMENT OF THE LOAN DOCUMENTS MAY BE SOUGHT THAT LIMITS THE RATES OF
INTEREST LEGALLY CHARGEABLE OR COLLECTIBLE.

         G. AN OPINION EXPRESSED "TO THE BEST OF OUR KNOWLEDGE", IS BASED SOLELY
UPON THE CURRENT ACTUAL KNOWLEDGE OF THOSE LAWYERS OF THE FIRM ACTIVELY ENGAGED
IN REPRESENTING THE COMPANY IN CURRENT MATTERS AND OUR INQUIRY OF OFFICERS,
INCLUDING THE CHIEF FINANCIAL OFFICER, OF THE COMPANY.

         THIS OPINION IS PROVIDED AS A LEGAL OPINION ONLY, AND NO OPINIONS MAY
BE INFERRED OR IMPLIED BEYOND THE MATTERS EXPRESSLY STATED HEREIN. THIS OPINION
IS SOLELY FOR THE BENEFIT OF THE AGENT AND THE BANKS (AND THEIR PERMITTED
ASSIGNEES) AND MAY NOT BE RELIED UPON IN ANY MANNER FOR ANY PURPOSE BY ANY OTHER
PERSON OR ENTITY WITHOUT OUR PRIOR WRITTEN CONSENT. THIS OPINION SPEAKS AS OF
ITS DATE ONLY, AND WE DISCLAIM ANY UNDERTAKING OR OBLIGATION TO ADVISE YOU OF
CHANGES THAT HEREAFTER MAY BE BROUGHT TO OUR ATTENTION.


                                             VERY TRULY YOURS,
