Item 5.  Other Events.

     (a) Effective June 28, 1999, John B. Bourke resigned and Lawrence D. Damron
became the Chief Financial Officer of the registrants. On July 8, 1999, Everest
issued a press release, attached as Exhibit 99.1, announcing the hiring of Mr.
Damron. The information contained in the press release is incorporated here by
reference.

     (b) Amended and Restated Credit Agreement. On June 30, 1999, the Company
refinanced its prior credit facility (the "Prior Credit Facility") with Harris
Trust and Savings Bank as agent bank, the same commercial bank that provided the
Prior Credit Facility. The new credit facility (the "New Credit Facility")
consists of three separate facilities: (i) a $35.0 million revolving credit
facility maturing on June 30, 2002 (the "Working Capital Facility"); (ii) a
$65.0 million acquisition financing facility maturing on June 15, 2005 (the
"Acquisition Facility"), which includes the requirement to convert all of the
borrowings outstanding thereunder on each of June 30, 2000, 2001 and 2002 to one
or more seven-year term loans with balloon payments due on June 15, 2005 (the
"Term Loans"); and (iii) a $40.0 million Y2K facility, available from January 1,
2000 through September 30, 2000, to finance government related accounts
receivable which are unpaid due to difficulties related to the year 2000. The
total amount drawn under the New Credit Facility may not exceed $140.0 million.
The New Credit Facility contains operating and financial covenants, including,
without limitation, requirements to maintain leverage and debt service coverage
ratios and minimum tangible net worth. In addition, the New Credit Facility
includes customary covenants relating to the delivery of financial statements,
reports, notices and other information, access to information and properties,
maintenance of insurance, payment of taxes, maintenance of assets, nature of
business, corporate existence and rights, compliance with applicable laws,
including environmental laws, transactions with affiliates, use of proceeds,
limitation on indebtedness, limitations on liens, limitations on certain mergers
and sales of assets, limitations on stock repurchases, and limitations on debt
payments and other distributions including prepayment or redemption of the
Company's Senior Subordinated Notes due 2008. The New Credit Facility contains
certain events of default after expiration of applicable grace periods,
including defaults relating to: (i) nonpayment of principal, interest, fees or
other accounts; (ii) violation of covenants; (iii) material inaccuracy of
representations and warranties; (iv) bankruptcy; (v) material judgments; (vi)
certain ERISA liabilities; and (vii) actual or asserted invalidity of any loan
documents.

     (c) Effective June 30, 1999, Everest consolidated three of its wholly-owned
Indiana corporate subsidiaries, Northwest Indiana Dialysis, Inc. ("NW
Indiana"), Lake Avenue Dialysis Center, Inc. ("Lake Avenue"), and Ohio Valley
Dialysis Center, Inc. ("Ohio Valley"), by statutory merger. NW Indiana and Lake
Avenue merged with and into Ohio Valley, with Ohio Valley being the surviving
corporation. Upon the effectiveness of the merger, Ohio Valley changed its name
to Everest Healthcare Indiana, Inc.

     (d) Acquisition of Englewood Dialysis Facility, L.L.C. Effective July 19,
1999, Everest acquired substantially all of the assets of Englewood Dialysis
Facility, L.L.C., a New Jersey limited liability company ("Englewood"),

The acquisition was made by Everest through its wholly-owned subsidiary,

officers or their votes are counted for such purpose.

     10.  Indemnification.  The Board of Directors is expressly authorized to

Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of the Corporation as consequence of such compromise or
arrangement, the compromise or arrangement and the reorganization shall, if
sanctioned by the court to which the application has been made, be binding on
all the creditors or class of creditors and/or on all the shareholders or class
of shareholders of the Corporation, as the case may be, and also on the
Corporation.

     SECTION 2.4.  Notice of Meetings.  Unless waived as herein provided,
                   ------------------
whenever stockholders are required or permitted to take any action at a meeting,
written notice of the meeting shall be given stating the place, date and hour of
the meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.  Such written notice shall be given not less than
five (5) days nor more than sixty (60) days before the date of the meeting to
each stockholder entitled to vote at the meeting or in the event of a merger,
consolidation, share exchange, dissolution or sale, lease or exchange of all or
substantially all of the Corporation's property, business or assets not less
than ten (10) days before the date of the meeting.  If mailed, notice is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at the stockholder's address as it appears on the records of the

if the time and place thereof are announced at the meeting in which the
adjournment is taken.  At the adjourned meeting the Corporation may conduct any

adjournment is for more than thirty days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

     SECTION 2.5.  Quorum and Adjourned Meetings.  Unless otherwise provided by
                   -----------------------------
law or the Corporation's Certificate of Incorporation, a majority of the shares
entitled to vote, present in person or represented by proxy, shall constitute a
quorum at a meeting of stockholders.  If less than a majority of the shares
entitled to vote at a meeting of stockholders is present in person or
represented by proxy at such meeting, a majority of the shares so represented
may adjourn the meeting from time to time without further notice.  At any
adjourned meeting at which a quorum is present, any business may be transacted
which might have been transacted at the original meeting.  The stockholders
present at a meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of such number of stockholders as may leave less
than a quorum.

     SECTION 2.6.  Fixing of Record Date.
                   ---------------------

     (a)  For the purpose of determining stockholders entitled to notice of or
to vote at any meeting of stockholders or any adjournment thereof, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which record date shall not be more than sixty nor less than ten
days before the date of such meeting.  If no record date is fixed by the Board
of Directors, the record date for determining stockholders entitled to notice of
or to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held.  A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting;

                                      -2-
<PAGE>

     (b)  For the purpose of determining stockholders entitled to consent to
corporate action in writing without a meeting, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is established by the Board of Directors, and
which date shall not be more than ten (10) days after the date on which the
resolution fixing the record date is adopted by the Board of Directors.  If no
record date has been fixed by the Board of Directors, the record date for
determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is required by
law, shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the Corporation by delivery
to its registered office in the State of New York, its principal office, or an
officer or agent of the Corporation having custody of the book in which the
proceedings of meetings of stockholders are recorded.  Delivery to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.  If no record date has been fixed by the Board
of Directors and prior action by the Board of Directors is required by law, the
record date for determining stockholders' consent to corporate action in writing
without a meeting shall be the close of business on the day on which the Board
of Directors adopts the resolution taking such prior action; and

     (c)  For the purpose of determining the stockholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect to any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix the record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty (60) days prior to such
action.  If no record date is fixed, the record date for determining the
stockholders for any such purpose shall be the close of business on the day on
which the Board of Directors adopts the resolution relating thereto.

     SECTION 2.7.  Voting List.  The officer who has charge of the stock ledger
                   -----------
of the Corporation shall prepare and make, at least ten (10) days before every
meeting of stockholders, a complete list of stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the place of the meeting during the
whole time thereof, and may be inspected by any stockholder who is present.

     SECTION 2.8.  Voting.  Unless otherwise provided by the Certificate of
                   ------
Incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by each stockholder. In all matters other than the election
of directors, the affirmative vote of the majority of shares present in person
or represented by proxy at the meeting and entitled to vote on the subject
matter shall be the act of the stockholders.  Directors shall be elected by
plurality of the

                                      -3-
<PAGE>

votes of the shares present in person or represented by a proxy at the meeting
entitled to vote on the election of directors.

     SECTION 2.9.   Proxies.  Each stockholder entitled to vote at a meeting of
                    -------
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.  A duly executed proxy
shall be irrevocable if it states that it is irrevocable and if, and only as
long as, it is coupled with an interest sufficient in law to support an
irrevocable power.  A proxy may remain irrevocable regardless of whether the
interest with which it is coupled is an interest in the stock itself or an
interest in the Corporation generally.

     SECTION 2.10.  Ratification of Acts of Directors and Officers.  Except as
                    ----------------------------------------------
otherwise provided by law or by the Certificate of Incorporation of the
Corporation, any transaction or contract or act of the Corporation or of the
directors or the officers of the Corporation may be ratified by the affirmative
vote of the holders of the number of shares which would have been necessary to
approve such transaction, contract or act at a meeting of stockholders, or by
the written consent of stockholders in lieu of a meeting.

     SECTION 2.11.  Informal Action of Stockholders.  Any action required to be
                    -------------------------------
taken at any annual or special meeting of stockholders of the Corporation, or
any action which may be taken at any annual or special meeting of such
stockholders, may be taken without a meeting, without prior notice and without a
vote, if a consent or consents in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.  Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing.  In the event that the action which is consented
to is such as would have required the filing of a certificate with any
governmental body, if such action had been voted on by stockholders at a meeting
thereof, the certificate filed shall state, in lieu of any statement required by
law concerning any vote of stockholders, that written consent had been given in
accordance with the provisions of Section 615 of the Business Corporation Law of
New York, and that written notice has been given as provided in such section.

     SECTION 2.12.  Organization.  Such person as the Board of Directors may
                    ------------
designate or, in the absence of such a designation, the president of the
Corporation or, in his or her absence, such person as may be chosen by the
holders of a majority of the shares entitled to vote who are present, in person
or by proxy, shall call to order any meeting of the stockholders and act as
chairman of such meeting.  In the absence of the secretary of the Corporation,
the chairman of the meeting shall appoint a person to serve as secretary at the
meeting.

     SECTION 11.1  Indemnification.  The Corporation shall indemnify, in
                   ---------------
accordance with and to the full extent now or hereafter permitted by law, any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (including, without limitation, any
action by or in the right of the Corporation), by reason of his acting as a
director of the Corporation (and the Corporation, in the sole discretion of the
Board of Directors, may so indemnify a person by reason of the fact that he is
or was an officer or employee of the Corporation or is or was serving at the
request of the Corporation in any other capacity for or on behalf of the
Corporation) against any liability or expense actually and reasonably incurred
by such person in respect thereof; provided, however, that the Corporation shall
not be obligated to indemnify any such director (i) with respect to proceedings,
claims or actions initiated or brought voluntarily by such person and not by way
of defense or brought against such person in response to a proceeding, claim or
action by such person against the Corporation, or (ii) for any amounts paid in
settlement of an action effected without the prior written consent of the
Corporation to such settlement or, (iii) if liability was incurred because the
director breached or failed to perform a duty he owes to the corporation and the
breach or failure to perform constitutes (a) a willful failure to deal fairly
with the corporation or its stockholders in connection with a matter in which
the director has a material conflict of interest, (b) a violation of criminal
law, unless the director had reasonable cause to believe his conduct was lawful
or no reasonable cause to believe his conduct was unlawful, (c) a transaction
from which the director derived an improper personal profit, or (d) willful
misconduct.  The termination of a proceeding by judgment, order, settlement or
conviction, or upon a plea of no contest or an equivalent plea, shall not, by
itself, create a presumption that indemnification of the director or officer is
not required.  A director or officer who seeks indemnification shall make a
written request to the Corporation.  Such indemnification is not exclusive of
any other right to indemnification provided by law, agreement or otherwise.

     SECTION 11.2  Determination of Right to Indemnification.  Unless otherwise

to indemnification shall be made by a majority

<PAGE>

vote of a quorum of the Board of Directors consisting of directors not at the
time parties to the same or related proceedings. If a quorum of disinterested
directors cannot be obtained, the determination will be made by majority vote of
a committee duly appointed by the Board of Directors and consisting solely of
two or more directors not at the time parties to the same or related
proceedings. Directors who are parties to the same or related proceedings may
participate in the designation of members of the committee.

                     AMENDED AND RESTATED CREDIT AGREEMENT

Harris Trust and Savings Bank
Chicago, Illinois
and the other Lenders from time to time party hereto

Ladies and Gentlemen:

         The undersigned, Everest Healthcare Services Corporation, a Delaware
corporation (the "Company"), refers to that certain Credit Agreement dated as of
April 16, 1996, as amended and thereafter restated by that certain Amended and
Restated Credit Agreement dated as of May 15, 1997, as amended and thereafter
restated by that certain Second Amended and Restated Credit Agreement dated as
of May 18, 1998, as amended and currently in effect among the Company, Harris
Trust and Savings Bank, as agent, and the lenders party thereto (the "Original
Credit Agreement"). The Company hereby requests that the aggregate commitments
available under the Original Credit Agreement be increased, that certain
additional amendments be made to the Original Credit Agreement and, for the sake
of clarity and convenience, that the Original Credit Agreement be restated in
its entirety as so amended. This Amended and Restated Credit Agreement amends
and replaces in its entirety the Original Credit Agreement, and from the
Effective Date all references made to the Original Credit Agreement in any Loan
Document or in any other instrument or document shall, without more, be deemed
to refer to this Amended and Restated Credit Agreement. This Amended and
Restated Credit Agreement shall become effective as of June 30, 1999 (the
"Effective Date"), and supersedes all provisions of the Original Credit
Agreement as of such date, upon the execution of this Amended and Restated
Credit Agreement by each of the parties hereto and the fulfillment of the
conditions precedent contained in Section 6.2 hereof. All capitalized terms used
herein without definition shall have the same meanings herein as such terms are
defined in Section 9.1 hereof.

SECTION 1. THE CREDITS.

         Section 1.1. Revolving Credit. Subject to the terms and conditions
hereof, each Lender, by its acceptance hereof, severally agrees to extend a
revolving credit (the "Revolving Credit") to the Company in the aggregate amount
of such Lender's commitment to extend the Revolving Credit as set forth on the
applicable signature page hereof or pursuant to Section 11.17 hereof (its
"Revolving Credit Commitment" and cumulatively for all Lenders the "Revolving
Credit Commitments") (subject to any reductions thereof pursuant to the terms
hereof) prior to the Termination Date. The Revolving Credit, subject to all of
the terms and conditions hereof, may be utilized by the Company in the form of
Revolving Loans and Letters of Credit, all as more fully hereinafter set forth;
provided, however, that the aggregate principal amount of the Revolving Loans
and L/C Obligations outstanding at any one time shall not at any time exceed the
lesser of (i) the Revolving Credit Commitments then in effect and (ii) the
Borrowing Base as then determined and computed. During the period from and
including the date thereof to but not including the Termination Date, the
Company may use the Revolving Credit Commitments by borrowing, repaying and
reborrowing Revolving Loans in whole or in part and/or by having the Agent issue
Letters of Credit, having such Letters of Credit expire or otherwise terminate
without having been drawn upon or, if drawn upon, reimbursing the Agent for each
such drawing, and having the Agent issue new Letters of Credit, all in
accordance with the terms and conditions of this Agreement. For all purposes of
this Agreement, where a determination of the unused or available amount of the
Revolving Credit Commitments is
<PAGE>

necessary, the Revolving Loans and L/C Obligations shall all be deemed to
utilize the Revolving Credit Commitments. The obligations of the Lenders
hereunder are several and not joint, and no Lender shall under any circumstances
be obligated to extend credit hereunder in excess of its Revolving Credit
Commitment.

         Section 1.2. Revolving Loans. Subject to the terms and conditions
hereof, the Revolving Credit may be availed of in the form of loans
(individually a "Revolving Loan" and collectively the "Revolving Loans"). Each
Borrowing of Revolving Loans shall be made ratably by the Lenders in accordance
with their Percentages. Each Borrowing of Revolving Loans shall be in an amount
of $250,000 or such greater amount which is an integral multiple of $50,000;
provided, however, that (i) a Borrowing made to repay a Reimbursement Obligation
may be made in the amount thereof and (ii) a Borrowing of Revolving Loans, or
any part thereof, which bears interest with reference to the Adjusted LIBOR Rate
shall be in such greater amount as is required by Section 2 hereof. All
Revolving Loans made by a Lender shall be evidenced by a single Revolving Credit
Note of the Company (individually a "Revolving Credit Note" and collectively the
"Revolving Credit Notes", which shall include the Revolving Credit Notes issued
pursuant to Section 11.17 hereof) payable to the order of such Lender in the
amount of its Revolving Credit Commitment, each Revolving Credit Note to be in
the form (with appropriate insertions) attached hereto as Exhibit A. Each
Revolving Credit Note shall be dated the date of issuance thereof, be expressed
to bear interest as set forth in Section 2 hereof, and be expressed to mature on
the Termination Date. Without regard to the principal amount of each Revolving
Credit Note stated on its face, the actual principal amount at any time
outstanding and owing by the Company on account thereof shall be the sum of all
Revolving Loans then or theretofore made thereon less all payments of principal
actually received thereon.

         Section 1.3.    Letters of Credit.

         (a) General Terms. Subject to the terms and conditions hereof, as part
of the Revolving Credit, the Agent shall issue standby letters of credit (each a
"Letter of Credit") for the account of the Company in U.S. Dollars in an
aggregate undrawn face amount up to the amount of the L/C Commitment. Each
Letter of Credit shall be issued by the Agent, but each Lender shall be
obligated to reimburse the Agent for such Lender's Percentage of the amount of
each draft drawn under a Letter of Credit and, accordingly, each Letter of
Credit shall be deemed to utilize the Revolving Credit Commitment of each Lender
pro rata in accordance with its Percentage thereof.

         (b) Applications. At any time before the Termination Date, the Agent
shall, at the request of the Company, issue one or more Letters of Credit to or
for the account of the Company in a form satisfactory to the Agent, with
expiration dates no later than 12 months from the date of issuance (or be
cancellable not later than 12 months from the date of issuance and each
renewal), in an aggregate face amount as set forth above, upon the receipt of an
application for the relevant Letter of Credit in the form then customarily
prescribed by the Agent duly executed by the Company (each an "Application").
For purposes of this Agreement and the other Loan Documents, Harris Trust and
Savings Bank Standby Letter of Credit SPL no. 33769 issued for the account of
WSKC Dialysis Services, Inc. (f/k/a West Suburban Kidney Center, S.C.) in favor
of Bankamerica Trust & Banking Corporation (Cayman) Limited shall be deemed a
Letter of Credit issued under this Agreement, and the Company agrees that from
and after the date of this Agreement the Company shall be jointly and severally
liable with WSKC Dialysis Services, Inc. for all obligations owing to Harris
Trust and
<PAGE>

Savings Bank with respect to such Letter of Credit, including all reimbursement
obligations arising under or relating to that certain Application and Agreement
for Irrevocable Standby Letter of Credit dated December 8, 1989, as amended,
with respect thereto (which agreement shall be deemed an Application for all
purposes of this Agreement and the other Loan Documents). On the Termination
Date, the Company shall pay to the Agent an amount equal to the aggregate
amounts undrawn on all Letters of Credit which are outstanding on that date to
be held as cash collateral for the Obligations of the Company with respect to
such Letters of Credit. Notwithstanding anything contained in any Application to
the contrary, (i) the obligation of the Company to pay fees in connection with
each Letter of Credit shall be as set forth in Section 3.3 hereof and (ii)
except during the existence of an Event of Default, the Agent will not call for
the funding by the Company of any amount under a Letter of Credit, or any other
form of collateral security for the obligations of the Company in connection
with such Letter of Credit, before being presented with a drawing thereunder
other than the collateral security contemplated by this Agreement and the
Collateral Documents. The Agent will promptly notify the Lenders of each
issuance by the Agent of a Letter of Credit. If the Agent issues any Letter of
Credit with an expiration date that is automatically extended unless the Agent
gives notice that the expiration date will not so extend beyond its then
scheduled expiration date, the Agent will give such notice of non-renewal before
the time necessary to prevent such automatic extension if, before such required
notice date, (i) the expiration date of such Letter of Credit if so extended
would be after the Termination Date, (ii) the Revolving Credit Commitments have
been terminated or (iii) a Default or an Event of Default has occurred and is
continuing and the Required Lenders have given the Agent instructions not to so
permit the extension of the expiration date of such Letter of Credit. The Agent
agrees to issue amendments to the Letter(s) of Credit increasing the amount, or
extending the expiration date, thereof at the request of the Company subject to
the conditions of Section 6 and the other terms of this Section 1.3. Without
limiting the generality of the foregoing, the Agent will not issue, amend or
extend the expiration date of any Letter of Credit if the Required Lenders
notify the Agent of any failure to satisfy or otherwise comply with the
conditions and terms of Section 6 and of this Section 1.3 and direct the Agent
not to take such action.

         (c) The Reimbursement Obligation. Subject to Section 1.3(b) hereof, the
obligation of the Company to reimburse the Agent for all drawings under a Letter
of Credit (a "Reimbursement Obligation") shall be governed by the Application
related to such Letter of Credit, except that (i) reimbursement of each drawing
shall be made in immediately available funds at the Agent's principal office in
Chicago, Illinois by no later than 12:00 noon Chicago time on the date when such
drawing is paid if the Company has been informed of such drawing by the Agent on
or before 11:30 a.m. Chicago time on the date when such drawing is paid or, if
notice of such drawing is given to Company after 11:30 a.m. Chicago time on the
date when such drawn is paid, by the end of such day and (ii) the Company's
Reimbursement Obligation shall bear interest (which the Company hereby promises
to pay), whether before or after judgment, until payment in full thereof at the
rate per annum equal to 2% plus the Applicable Margin for Revolving Loans plus
the Base Rate as in effect from time to time. If the Company does not make any
such reimbursement payment on the date due and the Participating Lenders fund
their participations therein in the manner set forth in Section 1.3(d) below,
then all payments thereafter received by the Agent in discharge of any of the
relevant Reimbursement Obligations shall be distributed in accordance with
<PAGE>

Section 1.3(d) below.

     (d) The Participating Interests. Each Lender (other than the Lender then
acting as Agent in issuing Letters of Credit), by its acceptance hereof,
severally agrees to purchase from the Agent, and the Agent hereby agrees to sell
to each such Lender (a "Participating Lender"), an undivided percentage
participating interest (a "Participating Interest"), to the extent of its
Percentage, in each Letter of Credit issued by, and each Reimbursement
Obligation owed to, the Agent. Upon any failure by the Company to pay any
Reimbursement Obligation in respect of a Letter of Credit at the time required
on the date the related drawing is paid, as set forth in Section 1.3(c) above,
or if the Agent is required at any time to return to the Company or to a
trustee, receiver, liquidator, custodian or other Person any portion of any
payment of any Reimbursement Obligation, each Participating Lender shall, not
later than the Business Day it receives a certificate in the form of Exhibit B
hereto from the Agent to such effect, if such certificate is received before
2:00 p.m. Chicago time, or not later than the following Business Day, if such
certificate is received after such time, pay to the Agent an amount equal to
such Lender's Percentage of such unpaid or recaptured Reimbursement Obligation
together with interest on such amount accrued from the date the related payment
was made by the Agent to the date of such payment by such Participating Lender
at a rate per annum equal to (i) from the date the related payment was made by
the Agent to the date 2 Business Days after payment by such Participating Lender
is due hereunder, the Federal Funds Rate for each such day and (ii) from the
date 2 Business Days after the date such payment is due from such Participating
Lender to the date such payment is made by such Participating Lender, the Base
Rate in effect for each such day. Each such Participating Lender shall
thereafter be entitled to receive its Percentage of each payment received in
respect of the relevant Reimbursement Obligation and of interest paid thereon,
with the Agent retaining its Percentage as a Lender hereunder.

     The several obligations of the Participating Lenders to the Agent under
this Section 1.3 shall be absolute, irrevocable and unconditional under any and
all circumstances whatsoever and shall not be subject to any set-off,
counterclaim or defense to payment which any Participating Lender may have or
have had against the Company, the Agent, any other Lender or any other Person
whatsoever. Without limiting the generality of the foregoing, such obligations
shall not be affected by any Default or Event of Default or by any reduction or
termination of any Revolving Credit Commitment of any Lender, and each payment
by a Participating Lender under this Section 1.3 shall be made without any
offset, abatement, withholding or reduction whatsoever. The Agent shall be
entitled to offset amounts received for the account of a Lender under this
Agreement against unpaid amounts due from such Lender to the Agent hereunder
(whether as fundings of participations, indemnities or otherwise), but shall not
be entitled to offset against amounts owed to the Agent by any Lender arising
outside this Agreement.

     (e) Indemnification. The Participating Lenders shall, to the extent of
their respective Percentages, indemnify the Agent (to the extent not reimbursed
by the Company) against any cost, expense (including reasonable counsel fees and
disbursements), claim, demand, action, loss or liability (except such as result
from the Agent's gross negligence or willful misconduct) that the Agent may
suffer or incur in connection with any Letter of Credit. The obligations of the
Participating Lenders under this Section 1.3(e) and all other parts of this
Section 1.3 shall survive termination of this Agreement, the Applications, and
all drafts and any other documents presented in connection with a drawing under
any Letter of Credit.
<PAGE>

    Section 1.4. Acquisition Financing Credit. (a) Subject to the terms and
conditions hereof, each Lender severally agrees to make on or after the date of
this Agreement one or more loans (individually an "Acquisition Financing Loan"
and collectively the "Acquisition Financing Loans") to the Company in the
aggregate amount of such Lender's commitment to make Acquisition Financing Loans
as set forth on the applicable signature page hereof or pursuant to Section
11.17 hereof (its "Acquisition Financing Commitment" and cumulatively for all
Lenders the "Acquisition Financing Commitments") (subject to increases thereof
pursuant to Section 1.8 hereof and to any reductions thereof pursuant to the
terms hereof) prior to the Acquisition Financing Termination Date. Each
Borrowing of Acquisition Financing Loans shall be made ratably by the Lenders in
accordance with their Percentages. Each Borrowing of Acquisition Financing Loans
shall be in an amount of $500,000 or such greater amount which is an integral
multiple of $50,000; provided, however, that a Borrowing of Acquisition
Financing Loans, or any part thereof, which bears interest with reference to the
Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2
hereof. The principal amount of each Acquisition Financing Loan shall
permanently reduce the amount available to the Company under each Lender's
Acquisition Financing Commitment, and no amount repaid or prepaid on any
Acquisition Financing Loan may be borrowed again. The proceeds of each
Acquisition Financing Loan shall be used solely for the purposes set forth in
Section 5.4(d) hereof. The obligations of the Lenders hereunder are several and
not joint, and no Lender shall under any circumstances be obligated to extend
credit hereunder in excess of its Acquisition Financing Commitment.

    (b) On June 30 of each of 2000, 2001, and 2002 (each, a "Conversion Date"),
the aggregate principal amount of Acquisition Financing Loans outstanding on
each Conversion Date shall convert into term loans (individually a "Term Loan"
and collectively the "Term Loans"). The conversion of outstanding Acquisition
Financing Loans into Term Loans on each Conversion Date shall be deemed a
Borrowing of Term Loans made ratably by the Lenders in accordance with their
Percentages of the outstanding Acquisition Financing Loans being converted. Each
Term Loan shall mature in quarterly principal installments, in an amount equal
to 1/28th of the original principal amount of the relevant Term Loan, commencing
on the date which is three calendar months after the date on which the relevant
Acquisition Financing Loans are converted into such Term Loan and continuing on
the same date of each and every third calendar month thereafter (or if no such
date exists for any one or more of such installments, then on the last day of
such third calendar month), with a final payment of both principal and interest
not sooner paid due on the Term Loan Final Maturity Date. No amount repaid or
prepaid on any Term Loan may be borrowed again.

    (c) All Acquisition Financing Loans made by a Lender to the Company, and all
Term Loans created by conversion thereof pursuant to this Section 1.4, shall
initially be evidenced by a single Acquisition Financing/Term Note of the
Company (individually an "Acquisition Financing/Term Note" and collectively the
"Acquisition Financing/Term Notes", which shall include the Acquisition
Financing/Term Notes issued pursuant to Section 11.17 hereof) payable to the
order of such Lender in the amount of its Acquisition Financing Commitment, each
Acquisition Financing/Term Note to be in the form (with appropriate insertions)
attached hereto as Exhibit C. Each Acquisition Financing/Term Note shall be
dated the date of issuance thereof, be expressed to bear interest as set forth
in Section 2 hereof, and be expressed to mature on the Term Loan Final Maturity
Date. Without regard to the principal amount of each Acquisition Financing/Term
Note
<PAGE>

stated on its face, the actual principal amount at any time outstanding and
owing by the Company on account thereof shall be the sum of all Acquisition
Financing Loans then or theretofore made thereon and all Term Loans created by
conversion thereof less all payments of principal actually received thereon.

     Section 1.5. Supplemental Revolving Credit. (a) Subject to the terms and
conditions hereof, and only for so long as the Acquisition Financing Commitments
remain outstanding, each Lender, by its acceptance hereof, severally agrees to
extend a supplemental revolving credit (the "Supplemental Revolving Credit") to
the Company in the aggregate amount of such Lender's commitment to extend the
Supplemental Revolving Credit as set forth on the applicable signature page
hereof or pursuant to Section 11.17 hereof (its "Supplemental Revolving Credit
Commitment" and cumulatively for all Lenders the "Supplemental Revolving Credit
Commitments") (subject to any reductions thereof pursuant to the terms hereof)
prior to the Supplemental Revolving Credit Termination Date. The Supplemental
Revolving Credit, subject to all of the terms and conditions hereof, may be
utilized by the Company in the form of loans (individually a "Supplemental
Revolving Loan" and collectively the "Supplemental Revolving Loans"), all as
more fully hereinafter set forth; provided, however, that:

               (i)  the aggregate principal amount of the Supplemental
         Revolving Loans outstanding at any one time shall not at any time
         exceed the difference between (x) the Supplemental Revolving Credit
         Commitments then in effect minus (y) the aggregate amount of loans and
         advances made by the Company or any Restricted Subsidiary to, and
         guarantees made by the Company or any Restricted Subsidiary in respect
         of the obligations of, any Person (other than Restricted Subsidiaries)
         in which the Company, directly or indirectly, holds an equity interest
         in (determined in accordance with Section 7.14 hereof, but determined
         exclusive of any such loans or advances financed with the proceeds of a
         Supplemental Revolving Loan); and

               (ii) the sum of the aggregate principal amount of the
         Supplemental Revolving Loans at any one time outstanding plus the
         original principal amount of all Acquisition Financing Loans made
         hereunder (without regard to any conversions thereof into Term Loans or
         any payments of principal on the Acquisition Financing/Term Notes)
         shall not at any time exceed the difference of (i) $65,000,000 plus any
         portion (up to $10,000,000) of the Revolving Credit Commitments
         converted into Acquisition Financing Commitments pursuant to Section
         1.8 hereof minus (ii) all amounts of the Acquisition Financing
         Commitments voluntarily terminated pursuant to Section 3.8 hereof.

The proceeds of each Supplemental Revolving Loan shall be used solely for the
purposes set forth in Section 5.4(b) hereof. During the period from and
including the date thereof to but not including the Supplemental Revolving
Credit Termination Date, the Company may use the Supplemental Revolving Credit
Commitments by borrowing, repaying and reborrowing Supplemental Revolving Loans
in whole or in part, all in accordance with the terms and conditions of this
Agreement.

     (b) Each Borrowing of Supplemental Revolving Loans shall be made ratably by
the Lenders in accordance with their Percentages. Each Borrowing of Supplemental
Revolving Loans shall be in an amount of $250,000 or such greater amount which
is an integral multiple of $50,000; provided, however, that a Borrowing of
Supplemental Revolving Loans, or any part thereof, which bears interest with
reference to the Adjusted LIBOR Rate shall be in such greater amount as is
<PAGE>

required by Section 2 hereof. All Supplemental Revolving Loans made by a Lender
shall be evidenced by a single Supplemental Revolving Credit Note of the Company
(individually a "Supplemental Revolving Credit Note" and collectively the
"Supplemental Revolving Credit Notes", which shall include the Supplemental
Revolving Credit Notes issued pursuant to Section 11.17 hereof) payable to the
order of such Lender in the amount of its Supplemental Revolving Credit
Commitment, each Supplemental Revolving Credit Note to be in the form (with
appropriate insertions) attached hereto as Exhibit D. Each Supplemental
Revolving Credit Note shall be dated the date of issuance thereof, be expressed
to bear interest as set forth in Section 2 hereof, and be expressed to mature on
the Supplemental Revolving Credit Termination Date. Without regard to the
principal amount of each Supplemental Revolving Credit Note stated on its face,
the actual principal amount at any time outstanding and owing by the Company on
account thereof shall be the sum of all Supplemental Revolving Loans then or
theretofore made thereon less all payments of principal actually received
thereon. The obligations of the Lenders hereunder are several and not joint, and
no Lender shall under any circumstances be obligated to extend credit hereunder
in excess of its Supplemental Revolving Credit Commitment.

     Section 1.6. Y2K Revolving Credit. (a) Subject to the terms and conditions
hereof, and commencing on January 1, 2000 (the "Y2K Commencement Date"), each
Lender, by its acceptance hereof, severally agrees to extend a revolving credit
to fund governmentrelated reimbursement interruptions associated with Year 2000
Problems of governmental entities (the "Y2K Revolving Credit") to the Company in
the aggregate amount of such Lender's commitment to extend the Y2K Revolving
Credit as set forth on the applicable signature page hereof or pursuant to
Section 11.17 hereof (its "Y2K Revolving Credit Commitment" and cumulatively for
all Lenders the "Y2K Revolving Credit Commitments") (subject to any reductions
thereof pursuant to the terms hereof) prior to the Y2K Revolving Credit
Termination Date. The Y2K Revolving Credit, subject to all of the terms and
conditions hereof, may be utilized by the Company in the form of loans
(individually a "Y2K Revolving Loan" and collectively the "Y2K Revolving
Loans"), all as more fully hereinafter set forth; provided, however, that the
aggregate principal amount of the Y2K Revolving Loans outstanding at any one
time shall not at any time exceed the lesser of (i) the Y2K Revolving Credit
Commitments then in effect and (ii) the Y2K Borrowing Base as then determined
and computed less the aggregate principal amount of all Revolving Loans and L/C
Obligations then outstanding. The proceeds of each Y2K Revolving Loan shall be
used solely for the purposes set forth in Section 5.4(e) hereof. During the
period from and including the Y2K Commencement Date to but not including the Y2K
Revolving Credit Termination Date, the Company may use the Y2K Revolving Credit
Commitments by borrowing, repaying and reborrowing Y2K Revolving Loans in whole
or in part, all in accordance with the terms and conditions of this Agreement.
The obligations of the Lenders hereunder are several and not joint, and no
Lender shall under any circumstances be obligated to extend credit hereunder in
excess of its Y2K Revolving Credit Commitment.

     (b) Each Borrowing of Y2K Revolving Loans shall be made ratably by the
Lenders in accordance with their Percentages. Each Borrowing of Y2K Revolving
Loans shall be in an amount of $250,000 or such greater amount which is an
integral multiple of $50,000; provided, however, that a Borrowing of Y2K
Revolving Loans, or any part thereof, which bears interest with reference to the
Adjusted LIBOR Rate shall be in such greater amount as is required by Section 2
hereof. All
<PAGE>

Y2K Revolving Loans made by a Lender shall be evidenced by a single Y2K
Revolving Credit Note of the Company (individually a "Y2K Revolving Credit Note"
and collectively the "Y2K Revolving Credit Notes", which shall include the Y2K
Revolving Credit Notes issued pursuant to Section 11.17 hereof) payable to the
order of such Lender in the amount of its Y2K Revolving Credit Commitment, each
Y2K Revolving Credit Note to be in the form (with appropriate insertions)
attached hereto as Exhibit E. Each Y2K Revolving Credit Note shall be dated the
date of issuance thereof, be expressed to bear interest as set forth in Section
2 hereof, and be expressed to mature on the Y2K Revolving Credit Termination
Date. Without regard to the principal amount of each Y2K Revolving Credit Note
stated on its face, the actual principal amount at any time outstanding and
owing by the Company on account thereof shall be the sum of all Y2K Revolving
Loans then or theretofore made thereon less all payments of principal actually
received thereon.

     Section 1.7. Manner of Borrowing Loans.

     (a) Generally. The Company shall give the Agent notice (which may be
written or oral, but if oral, promptly confirmed in writing, including notice by
telecopy) by 10:00 a.m. Chicago time on any Business Day of each request for any
Borrowing of Loans, in each case specifying the amount of each such Borrowing,
the type of Loan being requested, and the date such Borrowing is to be made
(which shall be a Business Day). The Agent shall notify each Lender of its
receipt of each such notice by 12:00 noon Chicago time on the Business Day any
Borrowing of Loans constituting the Base Rate Portion is to be made and by 12:00
noon Chicago time on the Business Day it receives such a request for any
Borrowing of Loans constituting a LIBOR Portion. Each Borrowing shall initially
constitute part of the relevant Base Rate Portion except to the extent the
Company has timely elected that such Borrowing, or any part thereof, constitute
part of a LIBOR Portion as provided in Section 2 hereof. Not later than 2:00
p.m. Chicago time on the date specified for any Borrowing of Loans to be made
hereunder, each Lender shall make the proceeds of its Loan comprising part of
such Borrowing available in immediately available funds to the Agent in Chicago,
Illinois, except in the case of the Term Loans, in which case each Lender shall
record the Term Loan made by it as part of the conversion of the Acquisition
Financing Loans, or such portion thereof, held by it into such Term Loan on its
books and records. Subject to all of the terms and conditions hereof, the
proceeds of each Lender's Loan shall be made available to the Company in
accordance with the instruction of the Company at the office of the Agent in
Chicago, Illinois and in funds there current.

     (b) Reimbursement Obligation. In the event the Company fails to give
notice pursuant to Section 1.7(a) above of a Borrowing equal to the amount of a
Reimbursement Obligation and has not notified the Agent by 11:30 a.m. Chicago
time on the day such Reimbursement Obligation becomes due that the Company
intends to repay such Reimbursement Obligation through funds not borrowed under
this Agreement, the Company shall be deemed to have requested a Borrowing of
Revolving Loans constituting part of the Base Rate Portion on such day in the
amount of the Reimbursement Obligation then due, subject to Section 6 hereof,
which Borrowing shall be applied to pay the Reimbursement Obligation then due.

     (c) Agent Reliance on Bank Funding. Unless the Agent shall have been
notified by a Lender before the date on which such Lender is scheduled to make
payment to the Agent of the proceeds of a Loan (which notice shall be effective
upon receipt) that such Lender does not intend to make such payment, the Agent
may assume that such Lender has made such payment when due
<PAGE>

and the Agent may in reliance upon such assumption (but shall not be required
to) make available to the Company the proceeds of the Loan to be made by such
Lender and, if any Lender has not in fact made such payment to the Agent, such
Lender shall, on demand, pay to the Agent the amount made available to the
Company attributable to such Lender together with interest thereon in respect of
each day during the period commencing on the date such amount was made available
to the Company and ending on (but excluding) the date such Lender pays such
amount to the Agent at a rate per annum equal to (i) from the date the related
advance was made by the Agent to the date 2 Business Days after payment by such
Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from
the date 2 Business Days after the date such payment is due from such Lender to
the date such payment is made by such Lender, the Base Rate in effect for each
such day. If such amount is not received from such Lender by the Agent
immediately upon demand, the Company will, on demand, repay to the Agent the
proceeds of the Loan attributable to such Lender with interest thereon at a rate
per annum equal to the interest rate applicable to the relevant Loan, but
without such payment being considered a payment or prepayment of a Loan under
Section 2.8 hereof, so that the Company will have no liability under Section 2.8
with respect to such payment.

     (d) Reliance. All requests for Borrowings and selection of interest rates
to be applicable thereto may be written or oral, including by telephone or
telecopy. The Company agrees that the Agent may rely on any such notice given by
any person the Agent in good faith believes is an Authorized Representative
without the necessity of independent investigation (the Company hereby
indemnifying the Agent and Lenders from any liability or loss ensuing from such
reliance), and in the event any such telephonic or other oral notice conflicts
with any written confirmation, such oral or telephonic notice shall govern if
the Agent has acted in reliance thereon.

     Section 1.8. Commitment Conversion Option. At any time prior to the
Acquisition Financing Termination Date, the Company shall have the option from
time to time to convert up to $10,000,000 of the Revolving Credit Commitments in
the aggregate into Acquisition Financing Commitments, provided that (a) the
Company shall give the Agent and the Lenders not less than 5 Business Days prior
written notice of the Company's exercise of such option, (b) the minimum amount
of Revolving Credit Commitments converted at any one time into Acquisition
Financing Commitments pursuant hereto shall not be less than $1,000,000 at such
time, or such greater amount which is an integral multiple of $1,000,000, (c)
the Revolving Credit Commitments shall be permanently reduced by the amount so
converted to Acquisition Financing Commitments, which reduction shall be applied
ratably among the Lenders in accordance with their Percentages, and (d) after
giving effect to the conversion, the Revolving Loans and L/C Obligations then
outstanding must not exceed the Revolving Credit Commitments in effect after
giving effect to such conversion.

Section 2.  Interest.

     Section 2.1. Options. Subject to all of the terms and conditions of this
Section 2, portions of the principal indebtedness evidenced by the Notes (all of
the indebtedness evidenced by Notes of the same type and, with respect to the
Term Loans, relating to the same Borrowing, and bearing interest at the same
rate for the same period of time being hereinafter referred to as a "Portion")
may, at the option of the Company, bear interest with reference to the Base Rate
("Base Rate Portions") or with reference to the Adjusted LIBOR Rate ("LIBOR
Portions"), and Portions may be converted from time to time from one basis to
the other. All of the indebtedness evidenced by
<PAGE>

the Notes of the same type and, with respect to the Term Loans, relating to the
same Borrowing, which is not part of a LIBOR Portion shall constitute a single
Base Rate Portion. All of the indebtedness evidenced by the Notes of the same
type and, with respect to the Acquisition Financing/Term Notes, relating to the
same Borrowing, which bears interest with reference to a particular Adjusted
LIBOR Rate for a particular Interest Period shall constitute a single LIBOR
Portion. Anything contained herein to the contrary notwithstanding, there shall
not be more than 6 LIBOR Portions applicable to Notes of the same type and, with
respect to the Term Loans, relating to the same Borrowing, outstanding at any
one time and each Lender shall have a ratable interest in each Portion. The
Company hereby promises to pay interest on each Portion applicable to it at the
rates and times specified in this Section 2.

     Section 2.2. Base Rate Portion. Each Base Rate Portion shall bear interest
(which the Company hereby promises to pay at the times herein provided) at the
rate per annum determined by adding the Applicable Margin to the Base Rate as in
effect from time to time, provided that if a Base Rate Portion is not paid when
due (whether by lapse of time, acceleration or otherwise), such Portion shall
bear interest (which the Company hereby promises to pay at the times hereinafter
provided), whether before or after judgment, and until payment in full thereof,
at the rate per annum determined by adding 2% to the sum of the Applicable
Margin plus the Base Rate as in effect from time to time. Interest on the Base
Rate Portions shall be payable on the last day of each March, June, September
and December in each year and at maturity of the applicable Notes, and interest
after maturity shall be due and payable upon demand.

     Section 2.3. LIBOR Portions. Each LIBOR Portion shall bear interest (which
the Company hereby promises to pay at the times herein provided) for each
Interest Period selected therefor at a rate per annum determined by adding the
Applicable Margin to the Adjusted LIBOR Rate for such Interest Period, provided
that if any LIBOR Portion is not paid when due (whether by lapse of time,
acceleration or otherwise), such Portion shall bear interest (which the Company
hereby promises to pay at the times hereinafter provided), whether before or
after judgment, and until payment in full thereof, through the end of the
Interest Period then applicable thereto at the rate per annum determined by
adding 2% to the interest rate otherwise applicable thereto and effective at the
end of such Interest Period, such LIBOR Portion shall automatically be converted
into and added to the applicable Base Rate Portion and shall thereafter bear
interest at the interest rate applicable to such Base Rate Portion after
default. Interest on each LIBOR Portion shall be due and payable on the last day
of each Interest Period applicable thereto (provided that if any Interest Period
is longer than three months, then interest on the LIBOR Portion having such
Interest Period shall be due and payable on the date occurring every three
months after the date such Interest Period began and on the last day of such
Interest Period), and interest after maturity shall be due and payable upon
demand. The Company shall notify the Agent on or before 10:00 a.m. Chicago time
on the third Business Day preceding the end of an Interest Period applicable to
a LIBOR Portion whether such LIBOR Portion is to continue as a LIBOR Portion, in
which event the Company shall notify the Agent of the new Interest Period
selected therefor, and in the event the Company shall fail to so notify the
Agent, such LIBOR Portion shall automatically be converted into and added to the
applicable Base Rate Portion as of and on the last day of such Interest Period.
The Agent shall promptly notify each Lender of each notice received from the
Company pursuant to the foregoing provisions. Each LIBOR Portion shall be in an
amount equal to $1,000,000 or such greater amount
<PAGE>

which is an integral multiple of $100,000. Anything contained herein to the
contrary notwithstanding, the obligation of the Lenders to create, continue or
effect by conversion any LIBOR Portion shall be conditioned upon the fact that
at the time no Default or Event of Default shall have occurred and be
continuing.

     Section 2.4. Manner of Rate Selection. The Company shall notify the Agent
by 10:00 a.m. Chicago time at least 3 Business Days prior to the date upon which
it requests that any LIBOR Portion be created or that any part of the applicable
Base Rate Portion be converted into a LIBOR Portion (such notice to specify in
each instance the amount thereof and the Interest Period selected therefor) and
the Agent shall advise each Lender of each such notice by 12:00 noon Chicago
time on the same Business Day it receives such notice. If any request is made to
convert a LIBOR Portion into the applicable Base Rate Portion, such conversion
shall only be made so as to become effective as of the last day of the Interest
Period applicable thereto. All requests for the creation, continuance or
conversion of Portions under this Agreement shall, subject to Section 2.6
hereof, be irrevocable.

     Section 2.5. Change of Law. Notwithstanding any other provisions of this
Agreement or the Notes, if at any time a Lender shall determine in good faith
that any change in applicable laws, treaties or regulations or in the
interpretation thereof makes it unlawful for such Lender to create or continue
to maintain LIBOR Portions, it shall promptly so notify the Agent (which shall
in turn promptly notify the Company and the other Lenders) and the obligation of
such Lender to create, continue or maintain any LIBOR Portion under this
Agreement shall be suspended until it is no longer unlawful for such Lender to
create, continue or maintain LIBOR Portions. The Company shall, on demand, if
the continued maintenance of a LIBOR Portion is unlawful, thereupon prepay the
outstanding principal amount of the LIBOR Portion, together with all interest
accrued thereon and all other amounts payable to the affected Lender with
respect thereto under this Agreement; provided, however, that the Company may
instead elect to convert the principal amount of the affected LIBOR Portion into
the applicable Base Rate Portion, subject to the terms and conditions of this
Agreement.

     Section 2.6. Unavailability of Deposits or Inability to Ascertain the
Adjusted LIBOR Rate. Notwithstanding any other provision of this Agreement or
the Notes, if prior to the commencement of any Interest Period, (a) any Lender
shall inform the Agent that such Lender has determined that United States dollar
deposits in the amount of any LIBOR Portion scheduled to be outstanding during
such Interest Period are not readily available to such Lender in the offshore
interbank market or (b) the Required Lenders shall advise the Agent that LIBOR
as determined by the Agent will not adequately and fairly reflect the cost to
such Lenders of funding such LIBOR Portion for such Interest Period, the Agent
shall promptly give notice thereof to the Company and each other Lender and the
obligations of the Lenders to create, continue or effect by conversion any LIBOR
Portion in such amount and for such Interest Period shall be suspended until the
circumstances giving rise to such termination no longer exist.

     Section 2.7. Taxes and Increased Costs. With respect to the LIBOR Portions,
if any Lender shall determine in good faith that any change in any applicable
law, treaty, regulation or guideline (including, without limitation, Regulation
D of the Board of Governors of the Federal Reserve System) or any new law,
treaty, regulation or guideline, or any interpretation of any of the foregoing
by any governmental authority charged with the administration thereof or any
central bank or other
<PAGE>

fiscal, monetary or other authority having jurisdiction over such Lender or its
lending branch or the Portions contemplated by this Agreement (whether or not
having the force of law) shall:

               (i)    impose, increase, or deem applicable any reserve, special
         deposit or similar requirement against assets held by, or deposits in
         or for the account of, or loans by, or any other acquisition of funds
         or disbursements by, such Lender which is not in any instance already
         accounted for in computing the Adjusted LIBOR Rate;

               (ii)   subject such Lender, the LIBOR Portions or any Note to
         the extent it evidences such Portions, to any tax (including, without
         limitation, any United States interest equalization tax or similar tax
         however named applicable to the acquisition or holding of debt
         obligations and any interest or penalties with respect thereto), duty,
         charge, stamp tax, fee, deduction or withholding in respect of this
         Agreement, any LIBOR Portion or any Note to the extent it evidences
         such a Portion, except such taxes as may be measured by the overall net
         income or gross receipts of such Lender or its lending branches and
         imposed by the jurisdiction, or any political subdivision or taxing
         authority thereof, in which such Lender's principal executive office or
         its lending branch is located;

               (iii)  change the basis of taxation of payments of principal and
         interest due from the Company to such Lender hereunder or under any
         Note to the extent it evidences any LIBOR Portion (other than by a
         change in taxation of the overall net income or gross receipts of such
         Lender or its lending branches); or

                  (iv) impose on such Lender any penalty with respect to the
         foregoing or any other condition regarding this Agreement, any LIBOR
         Portion, or any Note to the extent it evidences any LIBOR Portion;

and such Lender shall determine that the result of any of the foregoing is to
increase the cost (whether by incurring a cost or adding to a cost) to such
Lender of creating or maintaining any LIBOR Portion hereunder or to reduce the
amount of principal or interest received or receivable by such Lender, then the
Company shall pay on demand to the Agent for the account of such Lender from
time to time as specified by such Lender such additional amounts as such Lender
shall reasonably determine are sufficient to compensate and indemnify it for
such increased cost or reduced amount. If a Lender makes such a claim for
compensation, it shall provide to the Company (with a copy to the Agent) a
certificate setting forth in reasonable detail the computation of the increased
cost or reduced amount as a result of any event mentioned herein and such
certificate shall be deemed prima facie correct.

         Section 2.8. Funding Indemnity. In the event any Lender shall incur any
loss, cost or expense (including, without limitation, any loss (including loss
of profit), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired or contracted to be acquired by
such Lender to fund or maintain its part of any LIBOR Portion or the relending
or reinvesting of such deposits or other funds or amounts paid or prepaid to
such Lender) as a result of:

                   (i) any payment of a LIBOR Portion on a date other than the
         last day of the then applicable Interest Period for any reason, whether
         before or after default, and whether or not such payment is required by
         any provisions of this Agreement; or

                  (ii) any failure by the Company to create, borrow, continue or
         effect by conversion a LIBOR Portion on the date specified in a notice
         given pursuant to this
<PAGE>

     Agreement;

then, upon the demand of such Lender, the Company shall pay on demand to the
Agent for the account of such Lender such amount as will reimburse such Lender
for such loss, cost or expense. If a Lender requests such a reimbursement, it
shall provide the Company (with a copy to the Agent) with a certificate setting
forth in reasonable detail the computation of the loss, cost or expense giving
rise to the request for reimbursement and such certificate shall be deemed prima
facie correct.

     Section 2.9. Lending Branch. Each Lender may, at its option, elect to make,
fund or maintain its Loans hereunder at the branches or offices specified on the
signature pages hereof or on any Assignment Agreement executed and delivered
pursuant to Section 11.17 hereof or at such other of its branches or offices as
such Lender may from time to time elect. To the extent reasonably possible, a
Lender shall designate an alternative branch or funding office with respect to
its pro rata share of the LIBOR Portions to reduce any liability of the Company
to such Lender under Section 2.7 hereof or to avoid the unavailability of an
interest rate option under Section 2.6 hereof, so long as such designation is
not otherwise disadvantageous to the Lender.

     Section 2.10. Discretion of Lenders as to Manner of Funding.
Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of its
Notes in any manner it sees fit, it being understood, however, that for the
purposes of this Agreement all determinations hereunder (including
determinations under Sections 2.6, 2.7 and 2.8 hereof) shall be made as if each
such Lender had actually funded and maintained its share of each LIBOR Portion
during each Interest Period applicable thereto through the purchase of deposits
in the offshore interbank market in the amount of its share of such LIBOR
Portion, having a maturity corresponding to such Interest Period and bearing an
interest rate equal to LIBOR for such Interest Period.

     Section 2.11. Computation of Interest. All interest on the Notes, and all
fees, charges and commissions due hereunder, shall be computed on the basis of a
year of 360 days for the actual number of days elapsed, except that interest on
the Base Rate Portions of the Notes and on Reimbursement Obligations with
respect to Letters of Credit shall be computed on the basis of a year of 365 or
366 days (as the case may be) for the actual number of days elapsed.

     Section 2.12. Capital Adequacy. If any Lender shall determine that any
applicable law, rule or regulation regarding capital adequacy instituted after
the date hereof, or any change in the interpretation or administration of any
applicable law, rule or regulation regarding capital adequacy by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof or compliance by such Lender (or its
lending office) with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on such Lender's capital as a consequence of its obligations hereunder or credit
extended by it hereunder to a level below that which such Lender could have
achieved but for such law, rule, regulation, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy) by an
amount deemed by such Lender to be material, then from time to time, within 15
days after demand by such Lender, the Company shall pay to the Agent for the
account of such Lender such additional amount or amounts as will compensate such
Lender for such reduction. Any Lender claiming compensation under this Section
shall accompany its demand for compensation with a certificate (with a copy to
the Agent) setting forth the additional amount or
<PAGE>

amounts to be paid to it hereunder in reasonable detail, which certificate shall
be conclusive if reasonably determined. In determining such amount, such Lender
may use any reasonable averaging and attribution methods.

Section 3.  Fees, Payments, Reductions, Applications and Notations.

     Section 3.1. (a) Revolving Credit Commitment Fee. For the period from the
date hereof to but not including the Termination Date, the Company shall pay to
the Agent for the account of the Lenders in accordance with their Percentages a
commitment fee at the rate equal to 0.50% per annum on the average daily unused
amount of the Revolving Credit Commitments hereunder. Such fee shall be payable
in arrears on the last day of each March, June, September, and December in each
year (commencing with the first of such dates after the date hereof) and on the
Termination Date.

     (b) Y2K Revolving Credit Commitment Fee. For the period from January 1.
2000 to but not including the Y2K Revolving Credit Termination Date, the Company
shall pay to the Agent for the account of the Lenders in accordance with their
Percentages a commitment fee at the rate equal to 0.50% per annum on the average
daily unused amount of the Y2K Revolving Credit Commitments (including the full
amount thereof for all periods prior to the Y2K Commencement Date) hereunder.
Such fee shall be payable in arrears on the last day of each March, June,
September, and December in each year (commencing with the first of such dates
after the date hereof) and on the Y2K Revolving Credit Termination Date.

     Section 3.2. Acquisition Financing Commitment Fee. For the period from the
date hereof to but not including the Acquisition Financing Termination Date, the
Company shall pay to the Agent for the account of the Lenders in accordance with
their Percentages a commitment fee at the rate per annum equal to 0.75% per
annum on the average daily unused amount of the Acquisition Financing
Commitments hereunder. For purposes of this Section, Supplemental Revolving
Loans shall be deemed a utilization of the Acquisition Financing Commitments.
Such fee shall be payable in arrears on the last day of each March, June,
September, and December in each year (commencing with the first of such dates
after the date hereof) and on the date the Acquisition Financing Termination
Date.

     Section 3.3. Letter of Credit Fees. Quarterly in arrears, on the last day
of each March, June, September, and December in each year (commencing on the
first of such dates after the date hereof), the Company shall pay to the Agent,
for the benefit of the Lenders, a letter of credit fee at the Applicable Margin
per annum applied to the daily average face amount of Letters of Credit
outstanding during such quarter. In addition, the Company shall pay to the Agent
for its own use and benefit an issuance fee of 0.125% per annum as the issuing
bank and the Agent's standard drawing, negotiation, amendment and other
administrative fees for each Letter of Credit, as such standard fees may be
established by the Agent from time to time.

     Section 3.4. Audit Fees. The Company shall pay to the Agent for its own use
and benefit charges for audits of the Collateral by the Agent in such amounts as
the Agent may from time to time request (the Agent acknowledging and agreeing
that such charges shall be computed in the same manner as it at the time
customarily uses for the assessment of charges for similar collateral audits);
provided, however, that in the absence of any Default or Event of Default, the
Company shall not be required to pay the Agent for more than one such audit per
calendar year (determined exclusive of Y2K Audits which are at the expense of
the Company pursuant to Section 7.6 hereof).
<PAGE>

     Section 3.5. Agent's Fee. The Company shall pay to the Agent, for its own
use and benefit, such agency and arrangement fees as may from time to time be
mutually agreed upon by the Company and the Agent.

     Section 3.6. Voluntary Prepayments. The Company shall have the privilege of
prepaying the Revolving Credit Notes, the Y2K Revolving Credit Notes, and the
Supplemental Revolving Credit Notes in whole or in part (but if in part, then in
a minimum amount of $250,000 or such greater amount which is an integral
multiple of $50,000) and the Acquisition Financing/Term Notes in whole or in
part (but if in part, then in a minimum amount of $500,000 or such greater
amount which is an integral multiple of $50,000) at any time upon written notice
to the Agent (prior to 12:00 noon Chicago time on any Business Day and any such
notice received after such time to be treated as though received at the opening
of business on the next Business Day), which shall promptly so notify the
Lenders, by paying to the Agent for the account of the Lenders the principal
amount to be prepaid and (i) if such a prepayment prepays the Revolving Credit
Notes in full and is accompanied by the termination in whole of the Revolving
Credit Commitments, accrued interest thereon to the date of prepayment plus any
commitment fee which has accrued and is unpaid plus any prepayment fee due under
Section 3.8 hereof, (ii) if such a prepayment prepays the Acquisition
Financing/Term Notes in full, accrued interest thereon to the date of prepayment
plus, if accompanied by the termination in whole of the Acquisition Financing
Commitments, any commitment fee which has accrued and is unpaid plus any
prepayment fee due under Section 3.8 hereof, (iii) if such a prepayment prepays
the Supplemental Revolving Credit Notes in full and is accompanied by the
termination in whole of the Supplemental Revolving Credit Commitments, accrued
interest thereon to the date of prepayment plus any prepayment fee due under
Section 3.8 hereof, (iv) if such prepayment prepays the Y2K Revolving Credit
Notes in full and is accompanied by the termination in whole of the Y2K
Revolving Credit Commitments, accrued interest thereon to the date of prepayment
plus any commitment fee which has accrued and is unpaid plus any prepayment fee
due under Section 3.8 hereof, and (v) any amounts due to the Lenders under
Section 2.8 hereof.

     Section 3.7. Mandatory Prepayments. (a) The Company covenants and agrees
that if at any time the sum of the unpaid principal balance of the Revolving
Loans and the L/C Obligations outstanding at any one time shall be in excess of
the Borrowing Base as then determined and computed, the Company shall
immediately and without notice or demand pay over the amount of the excess to
the Agent for the account of the Lenders as and for a mandatory prepayment on
such Obligations, with each such prepayment first to be applied to the Revolving
Credit Notes until payment in full thereof with any remaining balance to be held
by the Agent as collateral security for the Obligations owing under the
Applications with respect to the Letters of Credit.

     (b) The Company covenants and agrees that if any time the sum of the unpaid
principal balance of the Y2K Revolving Credit Loans, the Revolving Loans, and
the L/C Obligations outstanding at any one time shall be in excess of the Y2K
Borrowing Base as then determined and computed, the Company shall immediately
and without notice or demand pay over the amount of the excess to the Agent for
the account of the Lenders as and for a mandatory prepayment on such
Obligations, with each such prepayment first to be applied to the Y2K Revolving
Credit Notes until payment in full thereof, then to the Revolving Credit Notes
until payment in full thereof, with any remaining balance to be held by the
Agent as collateral security for the Obligations owing under the
<PAGE>

Applications with respect to the Letters of Credit.

     (c) Within 90 days after the close of each fiscal year of the Company
(commencing with the fiscal year ending September 30, 2000), the Company shall
pay over to the Agent for the account of the Lenders as and for a mandatory
prepayment on the Acquisition Financing/Term Notes an amount equal to 50% of
Excess Cash Flow for the most recently completed fiscal year, provided that if
the Cash Flow Leverage Ratio computed as of the last day of any fiscal quarter
and as of the last day of the immediately preceding fiscal quarter (in each case
computed on a rolling four quarter basis) is less than 3.0 to 1.0, then the
mandatory prepayment due hereunder for all subsequent fiscal years shall be
reduced to 25% of Excess Cash Flow.  Mandatory prepayments of the Acquisition
Financing/Term Notes pursuant to this Section 3.7(b) shall be applied first to
the Term Loans then outstanding (which application shall be made to the most
recent Borrowing of Term Loans made to the Company and applied to the several
installments thereon in the inverse order of maturity) and then to the
Acquisition Financing Loans.

     (d) The Company covenants and agrees that if at any time the sum of the
unpaid principal balance of the Supplemental Revolving Loans then outstanding
plus the original principal amount of all Acquisition Financing Loans made
hereunder (determined without regard to any subsequent payments of principal
thereon) shall be in excess of the maximum permitted amounts thereof as
determined under Section 1.5(a)(i) or Section 1.5(a)(ii) hereof, the Company
shall immediately and without notice or demand pay over the amount of the excess
to the Agent for the account of the Lenders as and for a mandatory prepayment on
the Supplemental Revolving Credit Notes.

     (e) If the Company or any Subsidiary shall at any time or from time to time
make or agree to make a Disposition or shall suffer an Event of Loss resulting
in Net Cash Proceeds in excess of $1,000,000 in any fiscal year of the Company,
then (x) the Company shall promptly notify the Agent of such proposed
Disposition or Event of Loss (including the amount of the estimated Net Cash
Proceeds to be received by the Company or such Subsidiary in respect thereof)
and (y) promptly upon, and in no event later than the Business Day after,
receipt by the Company or the relevant Subsidiary of the Net Cash Proceeds of
such Disposition or Event of Loss, the Company shall prepay the Acquisition
Financing/Term Notes in an aggregate amount equal to 100% of the amount of such
Net Cash Proceeds; provided that in the case of each Disposition or Event of
Loss, if the Company states in its notice of such event that the Company or the
applicable Subsidiary intends to reinvest, within 180 days of the applicable
Disposition or receipt of Net Cash Proceeds from an Event of Loss, the Net Cash
Proceeds thereof in assets in a Permitted Line of Business, then so long as no
Default or Event of Default then or thereafter exists, the Company shall not be
required to make a mandatory prepayment under this Section in respect of such
Net Cash Proceeds to the extent such Net Cash Proceeds are actually reinvested
in such similar assets within such 180 day period. Promptly after the end of
such 180 day period, the Company shall notify the Agent whether the Company or
such Subsidiary has reinvested such Net Cash Proceeds in assets in a Permitted
Line of Business, and to the extent such Net Cash Proceeds have not been so
reinvested, the Company shall promptly prepay the Acquisition Financing/Term
Notes in the amount of such Net Cash Proceeds not so reinvested. The amount of
each such prepayment shall be applied first to the Term Loans then outstanding
(which application shall be made to the most recent Borrowing of Term Loans made
to the Company and applied to the several installments thereon in the inverse
order of maturity) and then to the Acquisition Financing Loans. The Company
acknowledges that
<PAGE>

its performance hereunder shall not limit the rights and remedies of the Lenders
for any breach of any other provisions of this Agreement.

     (f) If the Company or any Restricted Subsidiary issues any equity
securities in a public offering or issues at least $5,000,000 of debt securities
in a private placement at any time after the date hereof, the Company shall pay
to the Agent for the account of the Lenders, as and for a mandatory prepayment
on the Acquisition Financing/Term Notes, 50% of any Net Issuance Proceeds
(calculated without giving effect to any non-cash proceeds). Mandatory
prepayments of the Acquisition Financing/Term Notes made pursuant to this
Section shall be applied first to the Term Loans then outstanding (which
application shall be made to the most recent Borrowing of Term Loans made to the
Company and applied to the several installments thereon in the inverse order of
maturity) and then to the Acquisition Financing Loans.

     (g) Notwithstanding anything in this Section 3.7 to the contrary, prior to
the final maturity of the relevant Notes, the Company shall not be required to
make any prepayment of any LIBOR Portions pursuant to this Section 3.7 until the
last day of the Interest Period with respect thereto (provided that, in the case
of clause (e), any such cash collateral shall have the same effect as a
prepayment of the Loans for purposes of the Senior Subordinated Notes or any
issue of Subordinated Debt requiring that Subordinated Debt be retired out of
the proceeds of any such Disposition or Event of Loss after giving effect to any
mandatory prepayment of the Obligations) so long as (i) no Default or Event of
Default then exists or arises until the last day of the applicable Interest
Period and (ii) an amount equal to the principal amount of such LIBOR Portions
is deposited by the Company in a segregated cash collateral account with the
Agent for the benefit of the Lenders to be held in such account on terms
reasonably satisfactory to the Agent. The amount held on deposit in such account
shall if and when requested by the Company be invested in direct obligations of,
or obligations the principal of and interest on which are unconditionally
guaranteed by, the United States of America with a remaining maturity of one
year or less, or other investments mutually satisfactory to the Company and the
Agent. On the last day of such Interest Period, the amount held in such account
shall be applied so as to make such prepayment, and except during the
continuance of any Default or Event of Default, any balance remaining on deposit
in such account after such application shall be remitted to the Company.

     Section 3.8. Terminations. (a) Voluntary. The Company shall have the
privilege upon 5 Business Days prior notice to the Agent (which shall promptly
notify the Lenders) to ratably terminate the Revolving Credit Commitments and/or
the Acquisition Financing Commitments and/or the Supplemental Revolving Credit
Commitments and/or after March 31, 2000, the Y2K Revolving Credit Commitments in
whole or in part (but if in part then in the amount of $5,000,000 or such
greater amount which is an integral multiple of $5,000,000) and upon payment of
any prepayment premium required by the terms of the following sentence. On the
effective date of any such termination of the Commitments, or any part thereof,
the Company shall pay as a prepayment premium to the Agent for the account of
the Lenders, as liquidated damages for the loss of bargain and not as a penalty,
an amount equal to 0.50% per annum, in the case of any termination of the
Revolving Credit Commitments and 0.75% per annum, in the case of any termination
of the Acquisition Financing Commitments, times the aggregate Commitments then
being terminated multiplied by a fraction, the numerator of which is the number
of days remaining until September 30, 2000, and the denominator of which is 360
days. No partial terminations of the
<PAGE>

Revolving Credit Commitments may be made below the L/C Commitment then in
effect, unless the L/C Commitment is concurrently reduced by a like amount. No
partial terminations of the Acquisition Financing Commitments may be made below
the Supplemental Revolving Credit Commitments then in effect, unless the
Supplemental Revolving Credit Commitments are concurrently reduced by a like
amount. Not later than the termination date stated in such notice, there shall
be made such payments to the Agent as may be necessary to reduce the sum of the
aggregate outstanding principal amount of the relevant Loans to the amount to
which the relevant Commitments have been reduced, together with (x) any amount
due the Lenders under this Section 3.8 and under Section 2.8 hereof and (y) in
the case of a termination in whole, all interest, fees and other amounts due on
the Obligations. The foregoing to the contrary notwithstanding, (i) no
termination of the Revolving Credit Commitment may be effected hereunder if as a
result thereof the outstanding aggregate amount of L/C Obligations would exceed
the L/C Commitment as reduced by such termination and (ii) the relevant
Commitments may not be terminated below $5,000,000 except concurrently with
their termination in whole.

     (b) Mandatory Revolving Credit Terminations. If at any time Net Cash
Proceeds or Net Issuance Proceeds remain after the prepayment of the Acquisition
Financing/Term Notes in full pursuant to Section 3.7(e) or (f) hereof, the
Acquisition Financing Commitments and the Revolving Credit Commitments shall
terminate by an amount equal to 100% of such excess proceeds (first to the
Acquisition Financing Commitments until reduced to zero and then to the
Revolving Credit Commitments).

     (c) Mandatory Termination Upon a Change of Control. After the occurrence of
a Change of Control, the Required Lenders may, by written notice to the Company
at any time on or before the date occurring 90 days after the date the Company
notifies the Lenders of such Change of Control, terminate the remaining
Commitments and all other obligations of the Lenders hereunder on the date
stated in such notice (which shall in no event be sooner than 30 days after the
occurrence of such Change of Control). On the date the Commitments are so
terminated, all outstanding Obligations (including, without limitation, all
principal of and accrued interest on the Notes) shall forthwith be due and
payable without further demand, presentment, protest, or notice of any kind and
the Company shall immediately pay to the Lenders the full amount then available
for drawing under each Letter of Credit, such amount to be held by the Agent as
collateral security for the Letters of Credit and the Applications therefor and
any remaining Obligations (the Company agreeing to immediately make such payment
on the date the Commitments are so terminated and acknowledging and agreeing
that the Lenders would not have an adequate remedy at law for the failure by the
Company to honor any such demand and that the Lenders, and the Agent on their
behalf, shall have the right to require the Company to specifically perform such
undertaking whether or not any drawings or other demands for payment have been
made under any of the Letters of Credit).

     (d) Any termination of the Commitments pursuant to this Section may not be
reinstated.

     Section 3.9. Place and Application. All payments of principal, interest,
fees and any other Obligations shall be made to the Agent at its office 111 West
Monroe Street, Chicago, Illinois (or at such other place as the Agent may
specify) in immediately available and freely transferable funds at the place of
payment. All such payments shall be made without setoff or counterclaim and
without reduction for, and free from, any and all present or future taxes,
levies, imposts, duties, fees,
<PAGE>

charges, deductions, withholdings, restrictions or conditions of any nature
imposed by any government or political subdivision or taxing authority thereof.
Payments received by the Agent after 12:00 noon Chicago time shall be deemed
received as of the opening of business on the next Business Day. Except as
herein provided, all payments shall be received by the Agent for the ratable
account of the Lenders and shall be promptly distributed by the Agent to the
Lenders in accordance with their Percentages. Unless the Company otherwise
directs, payments (including prepayments) on any Loans shall be deemed first
applied to the applicable Base Rate Portion until payment in full thereof, with
any balance applied to the LIBOR Portions in the order in which their Interest
Periods expire. Any amount prepaid on the Revolving Credit Notes, Y2K Revolving
Credit Notes or Supplemental Revolving Credit Notes may, subject to all of the
terms and conditions hereof, be borrowed, repaid and borrowed again. No amounts
prepaid on the Acquisition Financing/Term Notes may be reborrowed, and any
partial prepayments (whether voluntary or mandatory) shall be applied first to
the Term Loans then outstanding (which application shall be made to the most
recent Borrowing of Term Loans made to the Company and applied to the several
installments thereon in the inverse order of maturity) and then to the
Acquisition Financing Loans. All payments (whether voluntary or required) shall
be accompanied by any amount due the Lenders under Section 2.8 hereof, but no
acceptance of such a payment without requiring payment of amounts due under
Section 2.8 shall preclude a later demand by the Lenders for any amount due them
under Section 2.8 in respect of such payment.

     Anything contained herein to the contrary notwithstanding, all payments and
collections received in respect of the Obligations and all proceeds of the
Collateral received, in each instance, by the Agent or any of the Lenders after
the occurrence and during the continuation of an Event of Default shall be
remitted to the Agent and distributed as follows:

          (a) first, to the payment of any outstanding costs and expenses
     incurred by the Agent in monitoring, verifying, protecting, preserving or
     enforcing the Liens on the Collateral or by the Agent in protecting,
     preserving or enforcing rights under the Loan Documents, and in any event
     all costs and expenses of a character which the Company has agreed to pay
     under Section 11.5 hereof (such funds to be retained by the Agent for its
     own account unless the Agent has previously been reimbursed for such costs
     and expenses by the Lenders, in which event such amounts shall be remitted
     to the Lenders to reimburse them for payments theretofore made to the
     Agent);

          (b) second, to the payment of any outstanding interest or other fees
     or amounts due under the Notes and the other Loan Documents, in each case
     other than for principal or in reimbursement or collateralization of L/C
     Obligations, ratably as among the Agent and the Lenders in accord with the
     amount of such interest and other fees or amounts owing each;

          (c) third, to the payment of the principal of the Notes and any unpaid
     Reimbursement Obligations, and to the Agent to be held as collateral
     security for any other L/C Obligations (until the Agent is holding an
     amount of cash equal to the then outstanding amount of all such L/C
     Obligations) and, during the existence of any Event of Default when the
     Obligations have been declared due and payable pursuant to Section 8.2 or
     8.3 hereof, to the payment of any unpaid Hedging Liability and ACH
     Liability, the aggregate amount paid to or held as collateral security for
     the Lenders to be allocated pro rata as among the
<PAGE>

     Lenders in accordance with the then respective aggregate unpaid principal
     balances of their Loans, interests in the Letters of Credit, and such
     unpaid Hedging Liability;

          (d) fourth, to the Agent and the Lenders ratably in accordance with
     the amounts of any other indebtedness, obligations or liabilities of the
     Company owing to each of them and secured by the Collateral Documents
     unless and until all such indebtedness, obligations and liabilities have
     been fully paid and satisfied; and

          (e) fifth, to the Company or whoever else may be lawfully entitled
     thereto.

In the event that the amount of any Hedging Liability is not fixed and
determined at the time any funds are to be allocated thereto pursuant to the
above provisions, the amount thereof shall be reasonably estimated by the Lender
(or its affiliate) to whom such Hedging Liability is owed and in a manner
reasonably acceptable to the Agent, with such funds so allocated to be held by
the Agent as collateral security until such Hedging Liability is fixed and
determined and the same shall then be applied to the Hedging Liability, with any
surplus reallocated among the Lenders, to cover any deficiency which would not
have existed had the exact amount of the Hedging Liability been known at the
time such funds were originally distributed.

     Section 3.10. Notations and Requests. All Borrowings made against the
Notes, the status of all amounts evidenced by the Notes as constituting part of
the applicable Base Rate Portion or LIBOR Portion and the rates of interest and
Interest Periods applicable to such Portions shall be recorded by the Lenders on
their books or, at their option in any instance, endorsed on the reverse side of
the Notes and the unpaid principal balances and status, rates and Interest
Periods so recorded or endorsed by the Lenders shall, absent manifest error, be
prima facie evidence in any court or other proceeding brought to enforce the
Notes of the principal amount remaining unpaid thereon, the status of such
Borrowings and the interest rates and Interest Periods applicable thereto. Prior
to any negotiation of any Note, the Lender holding such Note shall endorse
thereon the status of all amounts evidenced thereby as constituting part of the
Base Rate Portion or LIBOR Portion and the rates of interest and the Interest
Periods applicable thereto.

Section 4.  The Collateral and Guaranties.

     Section 4.1. Collateral. The Obligations shall be secured by valid and
enforceable security interests in and liens on all now owned or hereafter
acquired accounts, general intangibles, instruments, documents, chattel paper,
investment property, inventory, equipment, real estate and certain other goods
and assets of the Company and of each Restricted Subsidiary, in each case
whether now owned or hereafter acquired or arising, and all proceeds thereof.
The Company acknowledges and agrees that the Liens on the Collateral shall be
granted to the Agent for the benefit of itself, the Lenders and, with respect to
any Hedging Liability or ACH Liability, their affiliates, and shall be valid and
perfected first priority Liens subject, however, to Liens permitted by Section
7.13 hereof, and each case pursuant to one or more Collateral Documents from
such Persons in form and substance satisfactory to the Agent.

     Section 4.2. Guaranties. The payment and performance of the Obligations
shall at all times be guaranteed by each Restricted Subsidiary pursuant to a
guaranty agreement executed by such Restricted Subsidiary in form and substance
satisfactory to the Agent (individually a "Guaranty" and collectively the
"Guaranties").

     Section 4.3. Further Assurances. The Company agrees that it will, and will
cause each Restricted Subsidiary to, from time to time at the request of the
Agent or the Required Lenders,
<PAGE>

execute and deliver such documents and do such acts and things as the Agent or
the Required Lenders may reasonably request in order to provide for or perfect
or protect such Liens on the Collateral. In the event the Company or any
Restricted Subsidiary forms or acquires any Restricted Subsidiary after the date
hereof, the Company shall within 10 Business Days of such formation or
acquisition cause such newly formed or acquired Restricted Subsidiary to execute
a Guaranty and such Collateral Documents as the Agent may then require, and the
Company shall also deliver, or cause such Restricted Subsidiary to deliver, at
the Company's cost and expense, such other instruments, documents, certificates,
and opinions required by the Agent in connection therewith.

     Section 4.4. Liens on AfterAcquired Real Property. In the event that the
Company or any Restricted Subsidiary owns or hereafter acquires any real
property, at the request of the Agent or the Required Lenders, the Company
shall, or shall cause such Restricted Subsidiary to, execute and deliver to the
Agent (or a security trustee therefor) a mortgage or deed of trust acceptable in
form and substance to the Agent for the purpose of granting to the Agent for the
benefit of the Lenders a lien on such real property to secure the Obligations,
shall pay all taxes, costs and expenses incurred by the Agent in recording such
mortgage or deed of trust, and shall at its expense supply to the Agent a Phase
I environmental site assessment, a survey and a mortgagee's policy of title
insurance from a title insurer reasonably acceptable to the Agent insuring the
validity of such mortgage or deed of trust and its status as a first lien
(subject to liens permitted by this Agreement) on the real property encumbered
thereby.

Section 5.  Representations and Warranties.

      The Company represents and warrants to the Lenders as follows:

     Section 5.1. Organization and Qualification. The Company is duly organized,
validly existing and in good standing as a corporation under the laws of the
State of Delaware, has full and adequate corporate power to own its Property and
conduct its business as now conducted, and is duly licensed or qualified and in
good standing in each jurisdiction in which the nature of the business conducted
by it or the nature of the Property owned or leased by it requires such
licensing or qualifying.

     Section 5.2. Subsidiaries. Each Subsidiary is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
incorporated or organized, as the case may be, has full and adequate power to
own its Property and conduct its business as now conducted, and is duly licensed
or qualified and in good standing in each jurisdiction in which the nature of
the business conducted by it or the nature of the Property owned or leased by it
requires such licensing or qualifying. Schedule 5.2 hereto (as the same may be
deemed amended pursuant to Section 7.14(g) or 7.15 hereof) identifies each
Subsidiary, the jurisdiction of its incorporation or organization, as the case
may be, the percentage of issued and outstanding shares of each class of its
capital stock or other equity interests owned by the Company and the
Subsidiaries and, if such percentage is not 100% (excluding directors'
qualifying shares as required by law), a description of each class of its
authorized capital stock and other equity interests and the number of shares of
each class issued and outstanding. All of the outstanding shares of capital
stock and other equity interests of each Subsidiary are validly issued and
outstanding and fully paid and nonassessable and all such shares and other
equity interests indicated on Schedule 5.2 (as the same may be deemed amended
pursuant to Section 7.14(g) or 7.15 hereof) as owned by the Company or a
Subsidiary are owned, beneficially and of record, by the Company or such
Subsidiary free and clear of all Liens
<PAGE>

other than the Liens granted in favor of the Agent pursuant to the Collateral
Documents. Except as disclosed on Schedule 5.2 hereof, there are no outstanding
commitments or other obligations of any Subsidiary to issue, and no options,
warrants or other rights of any Person to acquire, any shares of any class of
capital stock or other equity interests of any Subsidiary.

     Section 5.3. Corporate Authority and Validity of Obligations. The Company
has full right and authority to enter into this Agreement and the other Loan
Documents executed by it, to make the borrowings herein provided for, to issue
its Notes in evidence thereof, to grant to the Agent the Liens described in the
Collateral Documents executed by the Company, and to perform all of its
obligations hereunder and under the other Loan Documents executed by it. Each
Restricted Subsidiary has full right and authority to enter into the Loan
Documents executed by it, to guarantee the Obligations, to grant to the Agent
the Liens described in the Collateral Documents executed by such Restricted
Subsidiary, and to perform all of its obligations under the Loan Documents
executed by it. The Loan Documents delivered by the Company and by each of its
Restricted Subsidiaries have been duly authorized, executed and delivered by
such Person and constitute valid and binding obligations of such Person
enforceable in accordance with their terms except as enforceability may be
limited by bankruptcy, insolvency, fraudulent conveyance or similar laws
affecting 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); and this Agreement and the other Loan Documents
do not, nor does the performance or observance by the Company or any Restricted
Subsidiary of any of the matters and things herein or therein provided for, (a)
contravene or constitute a default under any provision of law or any judgment,
injunction, order or decree binding upon the Company or any Restricted
Subsidiary or any provision of the charter, articles of incorporation or by-laws
of the Company or any Restricted Subsidiary, (b) contravene or constitute a
default under any covenant, indenture or agreement of or affecting the Company
or any Restricted Subsidiary or any of its Property, in each case where such
contravention or default is reasonably likely to have a Material Adverse Effect,
or (c) result in the creation or imposition of any Lien on any Property of the
Company or any Restricted Subsidiary other than the Liens granted in favor of
the Agent pursuant to the Collateral Documents.

     Section 5.4. Use of Proceeds; Margin Stock. The Company shall use the
proceeds of the Loans and other extensions of credit made available hereunder
solely for its general working capital purposes and for such other legal and
proper purposes as are consistent with all applicable laws, except that (a)
Revolving Loan proceeds shall not be used, directly or indirectly, to invest in,
or make loans or advances to, Persons who are not Restricted Subsidiaries, (b)
Supplemental Revolving Loan proceeds shall only be used by the Company to make
loans and advances, directly or indirectly through a Restricted Subsidiary, to
Persons (other than Restricted Subsidiaries) to the extent permitted by Section
7.14(i) hereof, (c) Letters of Credit shall only be issued in support of
insurance policy obligations of the Company or any Restricted Subsidiary or for
such other purpose as is acceptable to the Agent in its sole discretion, (d) the
proceeds of the Acquisition Financing Loans shall only be used (1) to make
Permitted Acquisitions, (2) to finance the acquisition and construction of new
dialysis or perfusion clinics and expansion to existing dialysis or perfusion
clinics and to refinance Revolving Loans which were used for such purpose;
provided that no more than $20,000,000 of the proceeds of the Acquisition
Financing Loans may be used pursuant to this subsection (2), and (e) the
proceeds of the Y2K Revolving Loans shall only be used to fund
<PAGE>

government-related reimbursement interruptions associated with Year 2000
Problems of governmental entities. Neither the Company nor any Subsidiary is
engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System), and no part of the proceeds of any
Loan or any other extension of credit made hereunder will be used to purchase or
carry any such margin stock or to extend credit to others for the purpose of
purchasing or carrying any such margin stock.

     Section 5.5. Financial Reports. The consolidated balance sheet of the
Company and its Subsidiaries as at September 30, 1998, and the related
consolidated statements of income, retained earnings and cash flows of the
Company and its Subsidiaries for the fiscal year then ended, and accompanying
notes thereto, which financial statements are accompanied by the audit report of
Ernst & Young, independent public accountants, and the unaudited interim
consolidated balance sheet of the Company and its Subsidiaries as at March 31,
1999, and the related consolidated statements of income and retained earnings of
the Company and its Subsidiaries for the 6 months then ended, heretofore
furnished to the Lenders, fairly present in all material respects the
consolidated financial condition of the Company and its Subsidiaries as at said
dates and the consolidated results of their operations and cash flows for the
periods then ended in conformity with generally accepted accounting principles
applied on a consistent basis. Neither the Company nor any Subsidiary has
contingent liabilities which are material to it other than as indicated on such
financial statements or, with respect to future periods, on the financial
statements furnished pursuant to Section 7.5 hereof.

     Section 5.6. No Material Adverse Change. Since March 31, 1999, there has
been no change in the condition (financial or otherwise) or business prospects
of the Company or any Subsidiary, except those occurring in the ordinary course
of business, none of which individually or in the aggregate have been materially
adverse.

     Section 5.7. Full Disclosure. The statements and information furnished to
the Lenders in connection with the negotiation of this Agreement and the other
Loan Documents and the commitments by the Lenders to provide all or part of the
financing contemplated hereby do not contain any untrue statements of a material
fact or omit a material fact necessary to make the material statements contained
herein or therein not misleading; the Lenders acknowledging that as to any
projections furnished to the Lenders, the Company only represents that the same
were prepared on the basis of information and estimates the Company believed to
be reasonable at the time made.

     Section 5.8. Trademarks, Franchises, and Licenses. The Company and its
Subsidiaries own, possess, or have the right to use all necessary patents,
licenses, franchises, trademarks, trade names, trade styles, copyrights, trade
secrets, know how and confidential commercial and proprietary information to
conduct their businesses as now conducted, without known conflict with any
patent, license, franchise, trademark, trade name, trade style, copyright or
other proprietary right of any other Person.

     Section 5.9. Governmental Authority and Licensing. The Company and its
Subsidiaries have received all licenses, permits, and approvals of all Federal,
state, local, and foreign governmental authorities, if any, necessary to conduct
their business as now conducted and to receive Medicare and Medicaid
reimbursement and/or payments for health care currently provided
<PAGE>

by them, including all certificates of need and other licenses, permits, and
approvals, if any, required to own and/or operate any health care facilities or
services currently owned or operated by them, in each case where the failure to
obtain or maintain the same is reasonably likely to have a Material Adverse
Effect. No investigation or proceeding which, if adversely determined, is
reasonably likely to result in revocation or denial of any material license,
permit, or approval, or of any right to receive reimbursement or payments under
Medicare or other governmental thirdparty reimbursement or prospective payment
program, is pending or, to the knowledge of the Company, threatened.

     Section 5.10. Good Title. The Company and its Subsidiaries each have good
and defensible title to their assets as reflected on the most recent
consolidated balance sheet of the Company and its Subsidiaries furnished to the
Lenders (except for sales of assets by the Company and its Subsidiaries in the
ordinary course of business), subject to no Liens other than such thereof as are
permitted by Section 7.13 hereof.

     Section 5.11. Litigation and Other Controversies. There is no litigation or
governmental proceeding or labor controversy pending, nor to the knowledge of
the Company threatened, against the Company or any Subsidiary which if adversely
determined is reasonably likely to have a Material Adverse Effect.

     Section 5.12. Taxes. Except as disclosed on Schedule 5.12 hereof, all tax
returns required to be filed by the Company or any Subsidiary in any
jurisdiction have, in fact, been filed, and all taxes, assessments, fees and
other governmental charges upon the Company or any Subsidiary or upon any of
their respective Properties, income or franchises, which are shown to be due and
payable in such returns, have been paid, except such taxes, assessments, fees
and governmental charges, if any, as are being contested in good faith and by
appropriate proceedings which prevent enforcement of the matter under contest
and as to which adequate reserves established in accordance with GAAP have been
provided. The Company does not know of any proposed additional tax assessment
against the Company or any of its Subsidiaries for which adequate provisions in
accordance with GAAP have not been made on their accounts. Adequate provisions
in accordance with GAAP for taxes on the books of the Company and each
Subsidiary have been made for all open years, and for its current fiscal period.

     Section 5.13. Approvals. No authorization, consent, license, or exemption
from, or filing or registration with, any court or governmental department,
agency or instrumentality, nor any approval or consent of the stockholders of
the Company, any Subsidiary, or any other Person, is or will be necessary to the
valid execution, delivery or performance by the Company of this Agreement or by
the Company or any Subsidiary of any other Loan Document, except for such
approvals which have been obtained prior to or concurrently with the execution
and delivery of this Agreement and which remain in full force and effect.

     Section 5.14. Affiliate Transactions. Except for agreements in effect on
the date hereof and described on Schedule 5.14 attached hereto, neither the
Company nor any Subsidiary is a party to any contracts or agreements with any of
its Affiliates (other than with WhollyOwned Subsidiaries) on terms and
conditions which are less favorable to the Company or such Subsidiary than would
be usual and customary in similar contracts or agreements between Persons not
affiliated with each other.

     Section 5.15. Investment Company; Public Utility Holding Company. Neither
the Company
<PAGE>

nor any Subsidiary is an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, or a "public utility holding company" within the meaning of the
Public Utility Holding Company Act of 1935, as amended.

     Section 5.16. ERISA. The Company and each other member of its Controlled
Group has fulfilled its obligations under the minimum funding standards of and
is in compliance in all material respects with ERISA and the Code to the extent
applicable to it and has not incurred any liability to the PBGC or a Plan under
Title IV of ERISA other than a liability to the PBGC for premiums under Section
4007 of ERISA. Neither the Company nor any Subsidiary has any contingent
liabilities with respect to any post-retirement benefits under a Welfare Plan,
other than liability for continuation coverage described in article 6 of Title I
of ERISA.

     Section 5.17. Compliance with Laws. The Company and each of its
Subsidiaries are in compliance with the requirements of all federal, state and
local laws, rules and regulations applicable to or pertaining to their
Properties or business operations (including, without limitation, the
Occupational Safety and Health Act of 1970, the Americans with Disabilities Act
of 1990, laws and regulations relating to the providing of health care services,
and laws and regulations establishing quality criteria and standards for air,
water, land and toxic or hazardous wastes and substances), where any such non-
compliance, individually or in the aggregate, is reasonably likely to have a
Material Adverse Effect. Neither the Company nor any Subsidiary has received
notice to the effect that its operations are not in compliance with any of the
requirements of applicable federal, state or local environmental, health and
safety statutes and regulations or are the subject of any governmental
investigation evaluating whether any remedial action is needed to respond to a
release of any toxic or hazardous waste or substance into the environment, where
any such non-compliance or remedial action, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect.

     Section 5.18. Other Agreements. Neither the Company nor any Subsidiary is
in default under the terms of any covenant, indenture or agreement of or
affecting the Company, any Subsidiary, or any of their Properties, which default
if uncured is reasonably likely to have a Material Adverse Effect.

     Section 5.19. No Default. No Default or Event of Default has occurred and
is continuing.

     Section 5.20. Solvency. The Company and its Subsidiaries are solvent, able
to pay their debts as they become due, and have sufficient capital to carry on
their business and all businesses in which they are about to engage.

     Section 5.21. Year 2000 Compliance. The Company has conducted a review and
assessment of the computer applications of the Company and its Subsidiaries and
has made inquiry of their material suppliers, service vendors (including data
processors) and customers, with respect to any defect in computer software, data
bases, hardware, controls and peripherals related to the occurrence of the year
2000 or the use at any time of any date which is before, on and after December
31, 1999, in connection therewith. Based on the foregoing review, assessment and
inquiry, the Company believes that no such defect would reasonably be expected
to have a Material Adverse Effect, except for government-related reimbursement
interruptions associated with Year 2000 Problems of governmental entities.

     and the Required Lenders, provided that in each case any consideration to
     be paid therefor (other than consideration in the form of additional
     Subordinated Debt permitted by Section 7.12(h) hereof) shall only be
     payable so long as no Default or Event of Default exists prior to or would
     result after giving effect to such payment;

          (b) nothing herein contained shall prevent the making of dividends or
     distributions out of earnings by a WhollyOwned Subsidiary to the Company;

     equity interest holders so long as no Default or Event of Default exists
     prior to or would result after giving effect to any such dividend, except
     that any Subsidiary which is either a partnership or limited liability
     company may make distributions to the extent necessary to allow each of its
     partners or members, as the case may be, to make payment of its federal and
     state income tax liability attributable to such Subsidiary's taxable income
     regardless of whether or not a Default or Event of Default then exists;

          (d) the Company may declare and pay dividends on its capital stock
     in an aggregate amount during any fiscal year not to exceed 10% of Net
     Income of the Company from the immediately preceding fiscal year so long as

     effect to any such dividend; and

          (e) nothing herein contained shall prevent the purchase, redemption
     or other acquisition or retirement of the capital stock of the Company in
     connection with the death, retirement or termination of any officer,

     hereunder or under the Indenture prior to or would result after giving
     effect to any such purchase, redemption or other acquisition or retirement.

   Section 7.18.  ERISA.  The Company shall, and shall cause each of its
Subsidiaries to, promptly pay and discharge all obligations and liabilities
arising under ERISA of a character which if unpaid or unperformed is reasonably
likely to result in the imposition of a Lien against any of its Properties.  The
Company shall, and shall cause each of its Subsidiaries to, promptly notify the

in ERISA) with respect to a Plan, (ii) receipt of any notice from the PBGC of
its intention to seek termination of any Plan or appointment of a trustee
therefor, (iii) its intention to terminate or withdraw from any Plan, and (iv)
the occurrence of any event with respect to any Plan which would result in the
incurrence by the Company or any of its Subsidiaries of any material liability,
fine or penalty, or any material increase in the contingent liability of the
Company or any of its Subsidiaries with respect to any post-retirement Welfare
Plan benefit.

   Section 7.19. Compliance with Laws. The Company shall, and shall cause each
of its Subsidiaries to, comply in all respects with the requirements of all
federal, state and local laws, rules, regulations, ordinances and orders
applicable to or pertaining to its Properties or business
<PAGE>

operations, where any such non-compliance, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect or could result in a Lien
upon any of their Property.

   Section 7.20. Burdensome Contracts with Affiliates. (a) The Company shall
not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, enter into or permit to exist any transaction or series of related
transactions (including, without limitation, the purchase, sale, lease or
exchange of any Property or the rendering of any service) with, or for the
benefit of, any Affiliate of the Company or its Restricted Subsidiaries (each an
"Affiliate Transaction"), other than (x) Affiliate Transactions permitted under
paragraph (b) below and (y) Affiliate Transactions on terms that are no less
favorable to the Company or such Restricted Subsidiary than those that could
reasonably have been obtained in a comparable transaction at such time on an
arm's length basis from a Person that is not an Affiliate of the Company or such
Restricted Subsidiary. All Affiliate Transactions (and each series of related
Affiliate Transactions which are similar or part of a common plan) involving
aggregate payments or other Property with a fair market value in excess of
$1,000,000 shall be approved by the Board of Directors of the Company or such
Restricted Subsidiary, as the case may be, such approval to be evidenced by a
Board Resolution stating that such Board of Directors has determined that such
transaction complies with the foregoing provisions. If the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction (or a
series of related Affiliate Transactions related to a common plan) that involves
aggregate payments or other property with a fair market value of more than
$5,000,000, the Company or such Restricted Subsidiary, as the case may be,
shall, prior to the consummation thereof, obtain a favorable opinion as to the
fairness of such transaction or series of related transactions to the Company or
the relevant Restricted Subsidiary, as the case may be, from a financial point
of view, from an independent financial advisor acceptable to the Agent and
deliver the same to the Agent.

     (b) The restrictions set forth in Section 7.20(a) above shall not apply to,
and the following shall be deemed not to be Affiliate Transactions: (i)

as determined in good faith by the Company's Board of Directors; (ii)
transactions exclusively between or among the Company and any of its Wholly-
Owned Subsidiaries or exclusively between or among such Wholly-Owned
Subsidiaries, provided such transactions are not otherwise prohibited by this
Agreement; (iii) any agreement described in Schedule 5.14 hereof or any
amendment thereto or any transaction contemplated thereby (including pursuant to
any amendment thereto) in any replacement agreement thereto so long as any such
amendment or replacement agreement is not more disadvantageous to the Lenders in
any material respect than the original agreement as in effect on the date
hereof; (iv) investments, acquisitions, loans, advances or guarantees permitted
by Section 7.14 hereof; (v) dividends and other restricted payments permitted by
Section 7.17 hereof; (vi) contracts pursuant to which the Company or a Wholly-
Owned Subsidiary provides management services to an Affiliate in exchange for
payments in cash or cash equivalents, that are not less favorable to the Company
or such Wholly-Owned Subsidiary than those that could reasonably be obtained in
a comparable transaction at such time on an arm's-length basis from a Person
that is not an Affiliate of the Company or such Wholly-Owned Subsidiary; and
(vii) leases of employees for payments in cash or cash equivalents that are
greater than or equal to the wage and benefit cost of such employees.

Subsidiaries would be changed in any material respect from the general nature of
the business engaged in by it as of the date of this Agreement or as of the date
such Person becomes a Subsidiary hereunder.

     Section 7.24. Subordinated Debt. The Company shall at all times ensure that
all Obligations now existing or hereafter arising constitute "Senior Debt", or

and conditions relating to any Subordinated Debt or make any voluntary
prepayment thereof or affect any voluntary redemption thereof or make any
payment on account of Subordinated Debt which is prohibited under the terms of
any instrument or agreement subordinating the same to the Obligations; provided,
however, that nothing contained herein shall prohibit any payment obligation
under Section 7 of the Alliance Purchase Agreement of Hurdle, Kuntz, BeTech,
Services, Perfusion, Czaplicka or Lewis from being satisfied by set-off in
accordance with the terms of the Alliance Purchase Agreement.

Subsidiaries.

provided herein, the Company shall not and shall not permit any of its
Restricted Subsidiaries directly or indirectly to create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or restriction of
any kind on the ability of any Restricted Subsidiary to: (1) pay dividends or
make any other distribution on any of such Restricted Subsidiary's capital stock

Subsidiary; (2) pay any indebtedness owed to the Company or any other Restricted
Subsidiary; (3) make loans or advances to the Company or any

Material Adverse Effect.

Arrangements, with all of the foregoing to effectively limit the amount of
interest that the Company must pay on notional amounts of not less than such
portion of the Term Loans to not more than a rate acceptable to the Agent in its
reasonable discretion. Any Hedging Arrangements entered into after the date of
this Agreement shall be on terms and conditions, and with such parties,
reasonably acceptable to the Agent.

and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers hereunder and under the other Loan Documents as are
designated to the Agent by the terms hereof and thereof together with such
powers as are reasonably incidental thereto. The Lenders expressly agree that
the Agent is not acting as a fiduciary of the Lenders in respect of the Loan
Documents, the Company or otherwise, and nothing herein or in any of the other
Loan Documents shall result in any duties or obligations on the Agent or any of
the Lenders except as expressly set forth herein. The Agent may resign at any
time by sending 20 days prior written notice to the Company and the Lenders. In
the event of any such resignation, the Required Lenders may appoint a new agent
after consultation with the Company (and, so long as no Default or Event of
Default exists, the Company's prior written consent) which shall succeed to all
the rights, powers and duties of the Agent hereunder and under the other Loan
Documents. Any resigning Agent shall be entitled to the benefit of all the
protective provisions hereof with respect to its acts as an agent hereunder, but
no successor Agent shall in any event be liable or responsible for any actions
of its predecessor. If the Agent resigns and no successor is appointed, the
rights and obligations of such Agent shall be automatically assumed by the
Required Lenders and (i) the Company shall be directed to make all payments due
each Lender hereunder directly to such Lender and (ii) the Agent's rights in the
Collateral Documents shall be assigned without representation, recourse or
warranty to the Lenders as their interests may appear.

     Section 10.2.  Rights as a Lender.  The Agent has and reserves all of
the rights, powers and duties hereunder and under the other Loan Documents as
any Lender may have and may exercise the same as though it was not the Agent.
The terms "Lender" and "Lenders" as used herein and in all other Loan Documents
shall, unless the context otherwise expressly indicates, include the Agent in
its individual capacity as Lender.

     Section 10.3. Standard of Care. The Lenders acknowledge that they have
received and approved copies of the Loan Documents and such other information
and documents concerning the transactions contemplated and financed hereby as
they have requested to receive and/or review. The Agent makes no representations
or warranties of any kind or character to the Lenders with respect to the
validity, enforceability, genuineness, perfection, value, worth or
collectibility hereof or of the Notes or any of the other Obligations or of the
Loan Documents or of the Liens provided for thereby or of any other documents
called for hereby or thereby or of the Collateral. The Agent need not verify the
worth or existence of the Collateral and may rely exclusively on reports of the
Company with respect thereto. Neither the Agent nor any director, officer,
employee, agent or representative thereof (including any security trustee
therefor) shall in any event be liable for any clerical errors
<PAGE>

or errors in judgment, inadvertence or oversight, or for action taken or omitted
to be taken by it or them hereunder or under the Loan Documents or in connection
herewith or therewith except for its or their own gross negligence or willful
misconduct.  The Agent shall not incur any liability to the Lenders under or in
respect of this Agreement or any other Loan Documents by acting upon any notice,
certificate, warranty, instruction or statement (oral or written) of anyone
(including anyone in good faith believed by it to be authorized to act on behalf
of the Company), unless it has actual knowledge of the untruthfulness of same.
The Agent may execute any of its duties hereunder by or through representatives,
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders for the default or misconduct of any such representatives, employees,
agents or attorneys-in-fact selected 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 shall incur no liability to the
Lenders and be fully protected in acting upon the advice of such counsel.  The
Agent shall be entitled to assume that no Default or Event of Default exists
unless notified to the contrary by a Lender.  The Agent shall in all events be
fully protected in acting or failing to act in accordance with the instructions
of the Required Lenders.  Upon the occurrence of an Event of Default hereunder,
the Agent shall take such action with respect to the enforcement of its Liens on
the Collateral and the preservation and protection thereof as it shall be
directed to take by the Required Lenders but, unless and until the Required
Lenders have given such direction, the Agent shall take or refrain from taking
such actions as the Agent determines are appropriate and in the best interest of
all Lenders.  The Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
the Agent by reason of taking or continuing to take any such action.  The Agent
may treat the owner of any Note as the holder thereof until written notice of
transfer shall have been filed with the Agent signed by such owner in form
satisfactory to the Agent.  Each Lender acknowledges that it has independently
and without reliance on the Agent or any other Lender and based upon such
information, investigations and inquiries as it deems appropriate made its own
credit analysis and decision to extend credit to the Company.  It shall be the
responsibility of each Lender to keep itself informed as to the creditworthiness
of the Company and the Agent shall have no liability to any Lender with respect
thereto.

     Section 10.4. Costs and Expenses. Each Lender agrees to reimburse the Agent
for all costs and expenses (including, without limitation, reasonable attorneys'
fees) suffered or incurred by the Agent or any security trustee in performing
its duties hereunder and under the other Loan Documents, or in the exercise of
any right or power imposed or conferred upon the Agent hereby or thereby, to the
extent that the Agent is not promptly reimbursed for same by the Company after
making request of the Company for payment thereof, or out of the Collateral, all
such costs and expenses to be borne by the Lenders ratably in accordance with
their Percentages.

     Section 10.5. Indemnity. The Lenders shall ratably indemnify and hold the
Agent, and its directors, officers, employees, agents, representatives or
attorneys-in-fact (including as such any security trustee therefor), harmless
from and against any liabilities, losses, costs or expenses suffered or incurred
by it hereunder or under the other Loan Documents or in connection with the
transactions contemplated hereby or thereby, regardless of when asserted or
arising, except to the extent it is promptly reimbursed for the same by the
Company or out of the Collateral and except to the extent that any event giving
rise to a claim was caused by the gross negligence or willful
<PAGE>

misconduct of the party seeking to be indemnified.

     Section 10.6. Hedging Liability/ACH Liability. By virtue of a Lenders'
execution of this Agreement or an Assignment Agreement pursuant to Section 11.17
hereof, as the case may be, any Affiliate of such Lender with whom the Company
has entered into a Hedging Arrangement or agreement or arrangement creating ACH
Liability shall be deemed a Lender party hereto for purposes of any reference in
a Loan Document to the parties for whom the Agent is acting, it being understood
and agreed that the rights and benefits of such Affiliate under the Loan
Documents consist exclusively of such Affiliate's right to share in payments and
collections out of the Collateral and the Guarantees as more fully set forth in
other provisions hereof.

Section 11. Miscellaneous.

     Section 11.1.  Withholding Taxes.

      (a) Payments Free of Withholding.  Except as otherwise required by law and
subject to Section 11.1(b) hereof, each payment by the Company under this
Agreement or the other Loan Documents shall be made without withholding for or
on account of any present or future taxes (other than overall net income taxes
on the recipient) imposed by or within the jurisdiction in which the Company is
domiciled, any jurisdiction from which the Company makes any payment, or (in
each case) any political subdivision or taxing authority thereof or therein.  If
any such withholding is so required, the Company shall make the withholding, pay
the amount withheld to the appropriate governmental authority before penalties
attach thereto or interest accrues thereon and forthwith pay such additional
amount as may be necessary to ensure that the net amount actually received by
each Lender and the Agent free and clear of such taxes (including such taxes on
such additional amount) is equal to the amount which that Lender or the Agent
(as the case may be) would have received had such withholding not been made.  If
the Agent or any Lender pays any amount in respect of any such taxes, penalties
or interest the Company shall reimburse the Agent or that Lender for that
payment on demand in the currency in which such payment was made.  If the
Company pays any such taxes, penalties or interest, it shall deliver official
tax receipts evidencing that payment or certified copies thereof to the Lender
or Agent on whose account such withholding was made (with a copy to the Agent if
not the recipient of the original) on or before the thirtieth day after payment.

      (b) U.S. Withholding Tax Exemptions.  Each Lender that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) shall
submit to the Company and the Agent on or before the earlier of the date the
initial Borrowing is made hereunder and 30 days after the date hereof, two duly
completed and signed copies of either Form 1001 (relating to such Lender and
entitling it to a complete exemption from withholding under the Code on all
amounts to be received by such Lender, including fees, pursuant to the Loan
Documents and the Obligations) or Form 4224 (relating to all amounts to be
received by such Lender, including fees, pursuant to the Loan Documents and the
Obligations) of the United States Internal Revenue Service.  Thereafter and from
time to time, each Lender shall submit to the Company and the Agent such
additional duly completed and signed copies of one or the other of such Forms
(or such successor forms as shall be adopted from time to time by the relevant
United States taxing authorities) as may be (i) requested by the Company in a
written notice, directly or through the Agent, to such Lender and (ii) required
under thencurrent United States law or regulations to avoid or reduce United
States withholding taxes on payments in respect of all amounts to be received by
such Lender, including fees, pursuant to the Loan Documents or the Obligations.
<PAGE>

     (c)  Inability of Lender to Submit Forms. If any Lender determines, as a
result of any change in applicable law, regulation or treaty, or in any official
application or interpretation thereof, that it is unable to submit to the
Company or Agent any form or certificate that such Lender is obligated to submit
pursuant to subsection (b) of this Section 11.1 or that such Lender is required
to withdraw or cancel any such form or certificate previously submitted or any
such form or certificate otherwise becomes ineffective or inaccurate, such
Lender shall promptly notify the Company and the Agent of such fact and the
Lender shall to that extent not be obligated to provide any such form or
certificate and will be entitled to withdraw or cancel any affected form or
certificate, as applicable.

     Section 11.2.  Non-Business Days. If any payment hereunder becomes due and
payable on a day which is not a Business Day, the due date of such payment shall
be extended to the next succeeding Business Day on which date such payment shall
be due and payable. In the case of any payment of principal falling due on a day
which is not a Business Day, interest on such principal amount shall continue to
accrue during such extension at the rate per annum then in effect, which accrued
amount shall be due and payable on the next scheduled date for the payment of
interest.

     Section 11.3.  No Waiver, Cumulative Remedies. No delay or failure on the
part of the Agent or any Lender in the exercise of any power or right shall
operate as a waiver thereof or as an acquiescence in any default, nor shall any
single or partial exercise of any right preclude any other or further exercise
thereof or the exercise of any other power or right. The rights and remedies
hereunder of the Agent and the Lenders are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

     Section 11.4.  Waivers, Modifications and Amendments. Any provision hereof
or of the other Loan Documents may be amended, modified, waived or released and
any Default or Event of Default and its consequences may be rescinded and
annulled upon the written consent of the Company and the Required Lenders;
provided, however, that without the written consent of each Lender no such
amendment, modification or waiver shall increase the amount or extend the terms
of such Lender's Commitments or reduce the amount of any principal of or
interest rate applicable to, or extend the maturity of, any Obligation owed to
it or reduce the amount of fees or other amounts to which it is entitled
hereunder or release any guaranty of any Obligations or release all or any
substantial (in value) part of the collateral security afforded by the Loan
Documents (except in connection with a sale or other disposition permitted to be
effected by the provisions hereof or of the Loan Documents) or change this
Section 11.4 or change the definition of "Required Lenders" or change the number
of Lenders required to take any action hereunder or under the other Loan
Documents. No amendment, modification or waiver of the Agent's protective
provisions shall be effective without the prior written consent of the Agent.

     Section 11.5.  Costs and Expenses. (a) The Company agrees to pay on demand
all reasonable costs and expenses of the Agent in connection with the
negotiation, preparation, execution and delivery of the Loan Documents and in
connection with any one or more assignments of the Obligations and Commitments
(as set forth in Section 11.17 hereof) and in connection with any consents
hereunder or thereunder and any waivers or amendments hereto or thereto,
including the reasonable fees and expenses of counsel for the Agent with respect
to all of the foregoing, and all recording, filing, title insurance or other
fees, costs and taxes incident to perfecting a Lien upon the collateral security
for the Obligations, and all reasonable costs and expenses (including reasonable
<PAGE>

attorneys' fees) incurred by the Agent, the Lenders or any other holders of the
Obligations in connection with a default or the enforcement of the Loan
Documents (including, without limitation, all such costs and expenses arising
out of any bankruptcy or insolvency proceeding relating to the Company or any
Restricted Subsidiary), and all reasonable costs, fees and taxes of the types
enumerated above incurred in supplementing (and recording or filing supplements
to) the Loan Documents in connection with assignments contemplated by Section
11.17 hereof if counsel to the Agent believes such supplements to be appropriate
or desirable. The Company agrees to indemnify and save the Lenders, the Agent
and any security trustee for the Agent or the Lenders harmless from any and all
liabilities, losses, costs and expenses incurred by the Lenders or the Agent in
connection with any action, suit or proceeding brought against the Agent, any
security trustee or any Lender by any Person which arises out of the
transactions contemplated or financed by any of the Loan Documents or out of any
action or inaction by the Agent, any security trustee or any Lender thereunder,
including without limitation those caused by the negligence of any party but
except for such thereof as is caused by the gross negligence or willful
misconduct of the party indemnified and except for costs or liabilities incurred
in suits which are exclusively among the Lenders or the Lenders and the Agent.
The provisions of this Section 11.5 and the protective provisions of Section 2
hereof shall survive payment of the Obligations.

     (b)  The Company unconditionally agrees to forever indemnify, defend and
hold harmless, and covenants not to sue for any claim for contribution against,
the Agent and the Lenders for any damages, costs, loss or expense, including
without limitation, response, remedial or removal costs, arising out of any of
the following: (i) any presence, release, threatened release or disposal of any
hazardous or toxic substance or petroleum by the Company or any Subsidiary or
otherwise occurring on or with respect to its property (whether owned or
leased), (ii) the operation or violation of any environmental law, whether
federal, state, or local, and any regulations promulgated thereunder, by the
Company or any Subsidiary or otherwise occurring on or with respect to its
property (whether owned or leased), (iii) any claim for personal injury or
property damage in connection with the Company or any Subsidiary or otherwise
occurring on or with respect to its property (whether owned or leased), and (iv)
the inaccuracy or breach of any environmental representation, warranty or
covenant by the Company or any Subsidiary made herein or in any promissory note,
mortgage, deed of trust, security agreement or any other instrument or document
evidencing or securing any Obligations or setting forth terms and conditions
applicable thereto or otherwise relating thereto, except for damages arising
from the willful misconduct or gross negligence of, or material breach of the
Loan Documents by, the party claiming indemnification. This indemnification
shall survive the payment and satisfaction of all Obligations and the
termination of this Agreement, and shall remain in force beyond the expiration
of any applicable statute of limitations and payment or satisfaction in full of
any single claim under this indemnification. This indemnification shall be
binding upon the successors and assigns of the Company and shall inure to the
benefit of Agent and the Lenders and their directors, officers, employees,
agents, and collateral trustees, and their successors and assigns.

     Section 11.6.  Documentary Taxes. The Company agrees that it will pay any
documentary, stamp or similar taxes payable in respect to any Loan Document,
including interest and penalties, in the event any such taxes are assessed,
irrespective of when such assessment is made and whether or not any credit to it
is then in use or available.
<PAGE>

     Section 11.7.  Survival of Representations. All representations and
warranties made herein and in the other Loan Documents and in certificates given
pursuant hereto or thereto shall survive the execution and delivery of this
Agreement and the other Loan Documents, and shall continue in full force and
effect with respect to the date as of which they were made as long as any credit
is in use or available hereunder.

     Section 11.8.  Construction. Nothing contained herein shall be deemed or
construed to permit any act or omission which is prohibited by the terms of any
Collateral Document, the covenants and agreements contained herein being in
addition to and not in substitution for the covenants and agreements contained

     Section 11.10. Lender's Obligations Several. The obligations of the Lenders

convenience of reference only and are not a part of this Agreement for any other
purpose.
<PAGE>

     Section 11.12. Severability of Provisions. Any provision of this Agreement
which is unenforceable or prohibited in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such unenforceability or
prohibition without invalidating the remaining provisions hereof or affecting
the validity or enforceability of such provision in any other jurisdiction. All
rights, remedies and powers provided in this Agreement and the other Loan
Documents may be exercised only to the extent that the exercise thereof does not
violate any applicable mandatory provisions of law, and all the provisions of
this Agreement and other Loan Documents are intended to be subject to all
applicable mandatory provisions of law which may be controlling and to be
limited to the extent necessary so that they will not render this Agreement or
the other Loan Documents invalid or unenforceable.

     Section 11.13. Counterparts. This Agreement may be executed in any number
of counterparts, and by different parties hereto on separate counterpart
signature pages, and all such counterparts taken together shall be deemed to
constitute one and the same instrument.

     Section 11.14. Binding Nature and Governing Law. This Agreement shall be
binding upon the Company and its successors and assigns, and shall inure to the
benefit of the Agent and the Lenders and the benefit of their successors and
permitted assigns, including any subsequent holder of an interest of the
Obligations. This Agreement and the rights and duties of the parties hereto
shall be construed and determined in accordance with, and shall be governed by,
the internal laws of the State of Illinois without regard to principles of
conflicts of law. The Company may not assign its rights hereunder without the
written consent of the Agent and the Lenders.

     Section 11.15. Entire Understanding. This Agreement, together with the
other Loan Documents, constitute the entire understanding of the parties with
respect to the subject matter hereof and any prior agreements, whether written
or oral, with respect thereto are superseded hereby.

     Section 11.16. Participations. Any Lender may grant participations in its
extensions of credit hereunder to any other bank or lending institution (a
"Participant") provided that (i) no Participant shall thereby acquire any direct
rights under this Agreement, (ii) no Lender shall agree with a Participant not
to exercise any of its rights hereunder without the consent of such Participant
except for rights which under the terms hereof may only be exercised by all
Lenders, and (iii) no sale of a participation in extensions of credit shall in
any manner relieve the selling Lender of its obligations hereunder.

     Section 11.17. Assignment Agreements. Each Lender may, from time to time
upon at least 5 Business Days notice to the Agent and the Company, assign to
other banks or lending institutions all or part of its rights and obligations
under this Agreement (including, without limitation, the indebtedness evidenced
by the Notes then owned by such assigning Lender, together with an equivalent
proportion of its obligation to make loans and advances and participate in
Letters of Credit hereunder) pursuant to an Assignment Agreement in the form
attached hereto as Exhibit I (the "Assignment Agreements"); provided, however,
that (i) each such assignment shall be of a constant, and not a varying,
percentage of the assigning Lender's rights and obligations under this Agreement
and the assignment shall cover the same percentage of such Lender's Commitments,
Loans, Notes and interests in Letters of Credit; (ii) unless the Agent otherwise
consents, the aggregate amount of the Commitments, Loans, Notes and interests in
the Letters of Credit of the assigning Lender being assigned pursuant to each
such assignment (determined as of the effective
<PAGE>

date of the relevant Assignment Agreement) shall in no event be less than
$5,000,000 and shall be an integral multiple of $1,000,000 and, unless the
assigning Lender shall have assigned all of its Commitments, Loans, Notes and
interests in Letters of Credit, the aggregate amount of Commitments, Loans,
Notes, and interests in Letters of Credit retained by the assigning Lender shall
in no event be less than $5,000,000; (iii) the Agent and, so long as no Event of
Default then exists, the Company must each consent, which consent shall not be
unreasonably withheld and shall be evidenced by execution of a counterpart of
the relevant Assignment Agreement in the space provided thereon for such
acceptance, to each such assignment to a party which was not an original
signatory of this Agreement; and (iv) the assigning Lender must pay to the Agent
a processing and recordation fee of $3,500 and any reasonable out-of-pocket
attorney's fees incurred by the Agent in connection with such Assignment
Agreement. Upon the execution of each Assignment Agreement by the assigning
Lender thereunder, the assignee lender thereunder, the Agent and so long as no
Event of Default then exists, the Company, and payment to such assigning Lender
by such assignee lender of the purchase price for the portion of the
indebtedness of the Company being acquired by it, (i) such assignee lender shall
thereupon become a "Lender" for all purposes of this Agreement with Commitments
in the amount set forth in such Assignment Agreement and with all the rights,
powers and obligations afforded a Lender hereunder, (ii) such assigning Lender
shall have no further liability for funding the portion of its Commitments
assumed by such other Lender and (iii) the address for notices to such assignee
Lender shall be as specified in the Assignment Agreement executed by it.
Concurrently with the execution and delivery of such Assignment Agreement, the
Company shall execute and deliver Notes to the assignee Lender in the respective
amounts of its Commitments and new Notes to the assigning Lender in the
respective amounts of its Commitments after giving effect to the reduction
occasioned by such assignment, all such Notes to constitute "Notes" for all
purposes of this Agreement and the other Loan Documents.

     Section 11.18. Confidentiality. Any information disclosed by the Company or
any of its Subsidiaries to the Agent or any Lender which was designated
proprietary or confidential at the time of its receipt by the Agent or such
Lender, and which is not otherwise in the public domain, shall not be disclosed
by the Agent or such Lender to any other Person except (i) to its independent
accountants and legal counsel (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such
information and instructed to keep such information confidential), (ii) pursuant
to statutory and regulatory requirements, (iii) pursuant to any mandatory court
order, subpoena or other legal process, (iv) to the Agent or any other Lender,
(v) pursuant to any agreement heretofore or hereafter made between such Lender
and the Company which permits such disclosure, (vi) in connection with the
exercise of any remedy under the Loan Documents, or (vii) subject to an
agreement containing provisions substantially the same as those of this Section,
to any participant in or assignee of, or prospective participant in or assignee
of, any Obligation or Commitment (it being understood that prior to any such
disclosures contemplated by clauses (ii) and (iii) above, the Agent or such
Lender shall, if practicable, give the Company prior written notice of such
disclosure).

     Section 11.19. Set-off. In addition to any rights now or hereafter granted
under applicable law and not by way of limitation of any such rights, upon the
occurrence of and during the continuation of any Event of Default, each Lender
and each subsequent holder of any Obligation is hereby authorized by the Company
at any time or from time to time, without notice to the Company or to
<PAGE>

any other Person, any such notice being hereby expressly waived, to setoff and
to appropriate and to apply any and all deposits (general or special, including,
but not limited to, indebtedness evidenced by certificates of deposit, whether
matured or unmatured, but not including trust accounts, and in whatever currency
denominated) and any other indebtedness at any time held or owing by that Lender
or that subsequent holder to or for the credit or the account of the Company,
whether or not matured, against and on account of the Obligations of the Company
to that Lender or that subsequent holder under the Loan Documents, including,
but not limited to, all claims of any nature or description arising out of or
connected with the Loan Documents, irrespective of whether or not (a) that
Lender or that subsequent holder shall have made any demand hereunder or (b) the
principal of or the interest on the Loans or Notes and other amounts due
hereunder shall have become due and payable pursuant to Section 8 and although
said obligations and liabilities, or any of them, may be contingent or
unmatured.

     Section 11.20. Sharing of Set-Off. Each Lender agrees with each other
Lender a party hereto that if such Lender shall receive and retain any payment,
whether by set-off or application of deposit balances or otherwise, on any of
the Loans or reimbursement obligations with respect to Letters of Credit in
excess of its ratable share of payments on all such Obligations then outstanding
to the Lenders, then such Lender shall purchase for cash at face value, but
without recourse, ratably from each of the other Lenders such amount of the
Loans or Reimbursement Obligations, or participations therein, held by each such
other Lenders (or interest therein) as shall be necessary to cause such Lender
to share such excess payment ratably with all the other Lenders; provided,
however, that if any such purchase is made by any Lender, and if such excess
payment or part thereof is thereafter recovered from such purchasing Lender, the
related purchases from the other Lenders shall be rescinded ratably and the
purchase price restored as to the portion of such excess payment so recovered,
but without interest.

     Section 11.21. Submission to Jurisdiction; Waiver of Jury Trial. The
Company hereby submits to the nonexclusive jurisdiction of the United States
District Court for the Northern District of Illinois and of any Illinois State
court sitting in the City of Chicago for purposes of all legal proceedings
arising out of or relating to this Agreement, the other Loan Documents or the
transactions contemplated hereby or thereby. The Company irrevocably waives, to
the fullest extent permitted by law, any objection which it may now or hereafter
have to the laying of the venue of any such proceeding brought in such a court
and any claim that any such proceeding brought in such a court has been brought
in an inconvenient forum. The Company, the Agent, and each Lender hereby
irrevocably waives any and all right to trial by jury in any legal proceeding
arising out of or relating to any Loan Document or the transactions contemplated
thereby.

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS EMPLOYMENT AGREEMENT (this "Agreement"), is entered into as of June
28, 1999 by and between LAWRENCE D. DAMRON, an Illinois resident ("Employee"),
and EVEREST HEALTHCARE SERVICES CORPORATION, a Delaware corporation (the
"Company").

     WHEREAS, the Company provides dialysis and other services to patients and
other clients through its subsidiaries, and provides management, operational and
other services to its subsidiaries and various other entities; and

     WHEREAS, the Company desires to employ Employee, and Employee desires to be
so employed, in accordance with the terms hereof.

     NOW, THEREFORE, in consideration of the mutual agreements and
understandings set forth herein and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the Company and the
Employee hereby agree as follows:

1.   Employment.
     ----------

     1.1. Engagement of Employee.  The Company agrees to employ Employee as
          ----------------------
Chief Financial Officer of the Company, and Employee accepts such employment by
the Company, during the period beginning on the Effective Date and ending on the
fifth anniversary thereof (the "Expiration Date"), unless sooner terminated
pursuant to Section 3 hereof (the "Employment Period").  The parties agree that
Employee's employment by the Company shall commence on June 28, 1999 (the
"Effective Date").

     1.2  Duties and Powers.  During the Employment Period, Employee will serve
          -----------------
as Chief Financial Officer of the Company, and will have such responsibilities,
duties and authorities as outlined on Exhibit A hereto and render such other
services of an executive and administrative character to the Company, its
subsidiaries and its affiliates, as the chief executive officer of the Company
or Board of Directors of the Company (the "Board") may from time to time direct.
Employee will devote his best efforts and his full business time and attention
(except for permitted vacation periods and reasonable periods of illness or
other incapacity) to the business and affairs of the Company, and shall perform
the duties and carry out the responsibilities assigned to him, to the best of
his ability, in a diligent, businesslike and efficient manner, and in a manner
which does not violate any fiduciary duties Employee owes the Company under
common or statutory law, for the purpose of advancing the Company.  Employee
acknowledges that his duties and responsibilities will require his full-time
business efforts and agrees that during the Employment Period he will not engage
in any other business activity or have any business pursuits or interests except
insignificant activities or interests which do not conflict or compete with the
business of the Company and its subsidiaries or interfere with the performance
of Employee's duties hereunder.

2.   Compensation.
     ------------

     2.1  Base Salary.  During the Employment Period, the Company will pay
          -----------
Employee a base salary at the rate of $235,000 per annum, or a greater amount as
determined by the Board in its sole discretion (the base salary in effect from
time to time is hereinafter referred to as the "Base Salary"), payable in
regular installments in accordance with the Company's general payroll practices
for salaried officers.  Employee shall be reviewed annually and may receive, but
the Company is not obligated to provide, increases in base salary depending on
the Employee's performance.

     2.2  Bonus Plan.  Employee shall be eligible to receive bonus compensation,
          ----------
in the sole discretion of the Board, after each fiscal year of the Company
ending during the Employment Period based on the Company's performance during
such fiscal year and Employee's contributions to such performance and in an
amount equal to up to forty-five percent (45%) of his annual Base Salary during
such fiscal year; provided, that the bonus compensation payable to Employee
following the September 30, 1999 fiscal year end of the Company shall not be
less than $32,000.  Bonuses in excess of forty-five percent (45%) of Base Salary
may be paid at the Company's sole discretion for performance that exceeds
targeted objectives.

     2.3  Benefits.  In addition to the compensation payable to Employee
          --------
hereunder, Employee will be entitled to the following benefits during the

3.   Termination.
     -----------

     3.1  Termination By Employee or the Company.  The Employment Period (i)
          --------------------------------------
shall automatically terminate immediately upon Employee's resignation (for or
without Good Reason, as defined below) or death, or (ii) may be terminated by
the Company upon written notice delivered to Employee for or without Cause (as
defined below) or by reason of Employee's Permanent Disability (as defined
below).

          (a) "Good Reason" shall mean a significant demotion or material
     diminution in Employee's duties and responsibilities; provided that
     Employee voluntarily terminates his employment with Company within 120 days
     after such event occurs; provided, further, that Good Reason shall not be
     deemed to exist for purposes hereof if, (1) the Company provides notice to
     Employee of any change in his duties or his responsibilities and Employee
     fails to provide written notice to the Company within 30 days of being
     notified of such change that he objects to such change and that such change
     constitutes a significant demotion or material diminution in Employee's
     duties and responsibilities hereunder, or (2) Cause then existed for the
     termination of Employee's employment hereunder and the Company notifies
     Employee thereof within 90 days of receiving notice from Employee that
     Employee is resigning for Good Reason, if any such notice is given, or of
     such Employee's resignation for Good Reason, if any such notice is not
     given.

          (b) "Cause" shall mean a determination by the Board in the exercise of
     its reasonable judgment that Employee has (i) committed an act or acts
     constituting a felony or other act involving dishonesty, a breach of his

<PAGE>

     under common or statutory law or fraud with respect to the Company or
     Affiliated Entity (as defined below) or (ii) willfully taken or willfully
     failed to take any action the consequence of which action or omission is
     materially damaging to the business, assets or financial condition of the
     Company or an Affiliated Entity. Without limiting the generality of the
     preceding sentence, the Company and Employee acknowledge and agree that
     "Cause" shall not include any breach by Employee of the terms and
     conditions of this Agreement, which breach, provided that the Board has
     determined it is of a nature that is capable of being cured, is cured by
     Employee within thirty (30) days after Employee receives written notice
     from the Company specifying the nature of such breach.

          (c) "Permanent Disability" shall mean, with respect to the Employee

     the absence of the Employee from his employment by reason of any mental or
     physical illness, disability or incapacity for a period of three months
     during any six-month period; provided, however, in either case, that such
     illness, disability or incapacity shall be determined to be of a permanent
     nature by a licensed physician selected by the Board and reasonably
     acceptable to the Employee.  The Employment Period shall end in the case of
     clause (i) and (ii) on the last day of such three-month period.
     Notwithstanding the foregoing, a condition shall not be a Permanent
     Disability if it is the result of (i) a willfully self-inflicted injury or
     willfully self-inflicted sickness or (ii) an injury or disease contracted,
     suffered, or incurred while participating in a criminal offense.

          (d) "Affiliated Entity" shall mean any entity which, directly or
     indirectly controls, is controlled by or is under common control with, the
     Company.

     3.2  Compensation After Termination or Expiration.
          --------------------------------------------

          (a) If the Employment Period is terminated by the Company for Cause
     then the Company shall have no further obligation hereunder or otherwise
     with respect to Employee's employment from and after the termination date
     except payment of Employee's Base Salary accrued through the effective date
     of such termination.

          (b) If the Employment Period is terminated (i) by the Company without
     Cause; or (ii) due to Employee's death or Permanent Disability; or (iii)
     due to Employee's resignation for or without Good Reason (as defined
     below), Employee (or his designated beneficiary) shall be entitled to
     receive (A) Severance Pay (as defined below) and (B) health and life
     insurance for up to 12 months from the date of termination on the same
     basis as provided to Employee prior to termination.

          "Severance Pay" shall mean a cash payment equal to a percentage of
     Employee's Base Salary, payable for one year from the date of such
     termination, in regular installments in accordance with the Company's
     regular payroll practices for salaried officers in effect at such time, as
     follows:

                                       4
<PAGE>

               (A) with respect to a termination by the Company without Cause,
          or resignation by Employee for Good Reason or due to Employee's death
          or Permanent Disability, 130% of the Base Salary; or

               (B) with respect to a termination due to Employee's resignation
          without Good Reason: (A) 130% of the Base Salary if the date of
          termination is on or after the third anniversary of the Effective
          Date; (B) 86% of the Base Salary if the date of termination is on or
          after the second anniversary, but prior to the third anniversary, of
          the Effective Date; (C) 43% of the Base Salary if the date of
          termination is on or after the first anniversary, but prior to the
          second anniversary, of the Effective Date; or (D) zero if the date of
          termination is prior the first anniversary of the Effective Date.

          (c) The Employee hereby agrees that upon any termination of the
     Employment Period for any reason the Company shall not have any liability
     to Employee except for the payments required to be made by this Section 3.2
     and except as otherwise set forth in Section 3.3(d), and without regard to
     any general or specific policies (whether written or oral) of the Company
     relating to the employment or termination of its employees.  The Company
     and the Employee acknowledge that it would be impractical or extremely
     difficult to fix the Employee's actual damages in the case of any such
     termination.  Therefore, the Company and Employee agree that the payments
     to be paid as provided for in this Section 3.2 and Section 3.3(d) shall
     constitute liquidated damages; provided, however, that the Employee shall
     be under no duty to mitigate such liquidated damages.  In return for
     tendering payment of such liquidated damages, regardless of whether after
     tender of such payment Employee accepts it, Employee for himself and his
     heirs, executors, administrators and assigns (collectively, the
     "Releasors") does hereby remise, release, and forever discharge as to the
     Company and any of its Affiliated Entities and their respective agents,
     officers, directors and employees, heirs, successors, assigns
     (collectively, the "Releasees"), all manners of action, cause and causes of
     action, suits, debts, dues, accounts, liabilities, covenants, contracts,
     agreements, claims, obligations, damages, injuries and demands
     (collectively, the "Actions") whatsoever of any kind and nature, whether
     foreseen or unforeseen, contingent or actual, liquidated or unliquidated,
     in law or in equity, which any Releasor has or may have against any
     Releasee except for claims for breaches by the Company of express
     provisions of Section 3.2 or Section 3.3(d) of this Agreement.  The
     Employee hereby covenants not to sue any Releasee relating to any Action.

          (d) Notwithstanding any provision hereof other than Section 3.3(d),
     after termination or expiration of the Employment Period for any reason (i)
     the Company shall continue to have all of its rights hereunder (including,
     without limitation, all rights under Section 4 hereof at law or in equity),
     and (ii) Employee shall continue to have all of his rights under Section
     3.2 and Section 3.3 hereof.

     3.3  Obligations On Termination.
          --------------------------

          (a) Upon the expiration or termination of the Employment Period for
     any reason, Employee shall be deemed to have resigned from all offices,
     directorships, trusteeships, or other positions he may then hold with the
     Company or an Affiliated Entity.  Such resignation shall be deemed
     effective immediately thereupon, without the requirement that a written
     resignation be delivered.

          (b) Employee agrees that following the expiration or termination of
     the Employment Period for any reason, he will provide any service which the
     Company may reasonably request to discharge its continuing obligations with
     respect to services performed by Employee for a period not to exceed 60
     days (and so long as such services do not interfere with any new position
     or employment of Employee), and in such events Employee will be entitled to
     compensation on a per diem basis at his then customary rate for such
     services in addition to all other payments due the Employee by the Company
     in accordance with the terms hereof.  Such rate shall be negotiated between
     the parties in good faith, or if they are unable to agree shall be 200% of
     Employee's Base Salary divided by 365.

          (c) The Employee hereby acknowledges and agrees that all personal
     property and equipment furnished to or prepared by the Employee in the
     course of or incident to his employment belong to the Company and shall be
     promptly returned to the Company upon termination of the Employment Period.
     "Personal property" includes, without limitation, all books, manuals,
     records, financial statements, reports, notes, contracts, lists,
     blueprints, and other documents or materials, or copies, summaries or
     excerpts thereof, and all other proprietary information relating to the
     business of the Company; provided, however, that nothing shall preclude the
     Employee from retaining or removing (i) his personal rolodex, calendars,
     personal files of business processes, personal education and general
     business materials ("Personal Files"); (ii) information not containing
     Confidential Information (as hereinafter defined in Section 4.5) or a trade
     secret obtained while in the employ of the Company; or (iii) the Employee's
     personal computer provided all Confidential Information is deleted.  The
     Employee cannot retain or remove personal property that is or contains
     Confidential Information or a trade secret obtained while in the employ of
     the Company. Prior to retaining or removing any personal property other
     than his Personal Files, the Employee will inform the Company of what
     personal property he intends to retain or remove. If a dispute arises
     between the Company and the Employee regarding the right of Employee to
     remove any such personal property, the parties shall arbitrate such dispute
     in a manner mutually agreeable to them.  Following termination, the
     Employee will not retain any written or other tangible material containing
     any Confidential Information or trade secrets, except as described above.

          (d) In the event the Employment Period expires or is terminated (other
     than due to the resignation or termination by Employee for the failure of
     the Company to (i) pay his Base Salary in accordance with Section 2.1 or
     bonus in accordance with Section 2.2, or (ii) pay or make available
     Comparable Benefits (as defined below) (the failures included

                                       6
<PAGE>

     in clauses (i) and (ii) are hereinafter collectively referred to as the
     "Termination Events")), the Company's sole liability to Employee shall be
     limited to, and Employee shall only be entitled to sue the Company for, the
     compensation due to him in accordance with Section 3.2. In the event the
     Employment Period is terminated due to the resignation by Employee for the
     occurrence of any Termination Event, Employee shall have the right to
     exercise any rights he has in law or equity, including the right to sue for
     damages and to render this Agreement of no further force or effect.
     "Comparable Benefits" means, for purposes of this Agreement, all employee
     benefits including, but not limited to, vacation, disability, death
     benefits, healthcare, pension and 401K plans, those benefits provided in
     Section 2.3, and other fringe benefits provided to other similarly situated
     Company executives ("Company Benefits") with respect to both the financial
     effect of such benefits to Employee and the terms and provisions of such
     benefits (which benefits must be within a range of no less than 90% of the
     Company Benefits).

4.   Covenant Not to Compete.
     -----------------------

     4.1  Employee's Knowledge.  Employee acknowledges and agrees that he has
          --------------------
occupied and will continue to occupy a position of trust and confidence with the
Company and has and will become familiar with the Company's trade secrets and
other proprietary and confidential information concerning the Company.  Employee
acknowledges and agrees that his services are of a special, unique and
extraordinary value to the Company and that the Company would be irreparably
damaged if Employee were to provide similar services to any person or entity in
violation of the provisions of this Agreement.  Employee further acknowledges
that the Company's relationships with its clients and other business partners
are among its most valuable assets which in many cases have been created over a
long period of time and, if lost, could not be replaced.

     4.2  Non-Compete.
          -----------

          (a) As consideration for the Company entering into this Agreement, and
     in recognition of the Company's proprietary interest in its business,

     engaging or proposing to engage in the Business (as defined below) anywhere
     in the Territory (as defined below).  "Business" shall mean the performance
     of activities related to:

          (i)  the provision of dialysis treatments or services utilized in
               connection with any dialysis treatment;

          (ii) the purchase, sale or establishment of dialysis operations and
               facilities;

          (iv)  extracorporeal blood handling as provided by the Company or
                any Affiliated Entity as of the date hereof.

     Notwithstanding the foregoing to the contrary, the Employee may engage in

     practice management company or managed care company other than any company
     the principal business of which is providing management services for
     nephrology or renal dialysis practices and (y) the sale of products used in
     dialysis treatments or extracorporeal blood handling.  "Restricted Period"
     shall mean the period commencing on the Effective Date hereof and ending on
     the date which is the second anniversary of the first to occur of the
     Expiration Date and the date Employee's employment with the Company is
     terminated for any reason.

          (b) The Restricted Period shall be automatically extended for a period
     equal to any period that Employee is in breach of the restrictive covenants
     set forth in this Section 4 (the "Restrictive Covenants").  "Territory"
     shall mean the area included within a 20 mile radius of any location where
     the Company or any of its Affiliated Entities provides services or engages
     in the Business, including any Medicare certified outpatient renal dialysis
     facility or any other facility providing any services or engaging in any
     activities of the Business which is (x) owned, operated or managed by the
     Company or any Affiliated Entity on the Expiration Date or the date on
     which the Employment Period is otherwise terminated or at any time during
     the 18 months preceding such date, or (y) for which the Company or any
     Affiliated Entity during the nine months preceding the Expiration Date or
     the date on which the Employment Period is otherwise terminated, was
     actively engaged in efforts to establish, acquire, manage or operate (each
     such facility is hereinafter referred to as a "Facility").  With respect to
     the Territory, Employee specifically acknowledges that the Company plans to
     conduct the Business throughout the United States and to undertake to
     expand the Business throughout the United States.  If Employee's employment
     with the Company is terminated within the six months following a Change of
     Control (as defined below), the term "Facility," as defined for these
     purposes, shall not include those facilities which are owned, managed, or
     operated by an Affiliated Entity which became an Affiliated Entity as a
     result of the transaction which also resulted in the Change of Control.
     "Change of Control" shall mean any person or entity, other than a

     an underwritten public offering registered under the Securities Act of
     1933, as amended, of shares of the Company's common stock in which the
     price per share paid by the public for such securities will be at least
     $10, reflecting a post-offering market capitalization for the Company of at
     least $150 million.

     4.3  Non-Solicitation.  Without limiting the generality of the provisions
          ----------------
of Section 4.2 hereof, Employee hereby agrees that, during the Restricted
Period, he will not, directly or

                                       8
<PAGE>

indirectly, solicit, or participate as employee, agent, consultant, stockholder,
director, partner or in any other individual or representative capacity, in any
business which solicits business from any person, firm, corporation or other
entity which was a client or other business partner of the Company during the
term of this Agreement or any referring physician or any owner of facilities
operated by the Company or its Affiliated Entities and, in each instance, who or
which is located in the Territory, or from any successor in interest to any such
person, firm, corporation or other entity who or which is located in the
Territory, for the purpose of securing business relationships or contracts
related to the Business; provided, however, that nothing contained herein shall
be construed to prohibit or restrict Employee from soliciting business from any
such parties on behalf of the Company in performance of his duties as an
employee of the Company required under and as specifically contemplated by
Section 1 above.

     4.4  Interference with Relationships.  During the Restricted Period,

capacity:  (i) except on behalf of the Company, employ or engage, recruit or
solicit for employment or engagement, any person who is or becomes employed or
engaged by the Company or its Affiliated Entities during the Restricted Period
or during the eighteen month period preceding the Restricted Period, or
otherwise seek to influence or alter any such person's relationship with the
Company or its Affiliated Entities, or (ii) solicit or encourage any client or
other business partner of the Company or its Affiliated Entities or any
referring physician or any owner of facilities operated or managed by the
Company or its Affiliated Entities to terminate or otherwise alter his
relationship with the Company or its Affiliated Entities.

     4.5  Confidential Information.  The Employee agrees that during the
          ------------------------
Employment Period or at all times thereafter, he shall not disclose to any
person or entity not employed by the Company and not engaged to render services
to the Company or otherwise use any Confidential Information obtained while in
the employ of the Company, except on behalf of the Company in accordance with
its policies or as such disclosure may be required by law or a court order.  As
used in this Agreement, "Confidential Information" shall mean any information
relating to the business or affairs of the Company, Peak Liquidating, L.L.C., a
limited liability company formed under the laws of the State of Delaware
("Peak"), any Affiliated Entities, or any of their clients or other business
partners, including but not limited to information relating to financial
statements, client or other business partner identities, potential clients,
employees, information, analyses, or other proprietary information used by the
Company, Peak, or any Affiliated Entities in connection with their businesses;
provided, however, that Confidential Information shall not include any
information which is in the public domain or becomes known in the industry
through no wrongful act on the part of Employee or is approved for disclosure by
the Company.  Employee acknowledges that the Confidential Information is vital,
sensitive, confidential and proprietary to the Company, Peak and the Affiliated
Entities.

     4.6  Blue-Pencil.  If any court of competent jurisdiction shall at any time
          -----------
deem the term of this Agreement or any particular Restrictive Covenant too
lengthy or the Territory too extensive, the other provisions of this Section 4
shall nevertheless stand, the Restricted Period herein shall be deemed to be the
longest period permissible by law under the circumstances and the Territory
herein shall be deemed to comprise the largest territory permissible by law
under the

                                       9
<PAGE>

circumstances. The court in each case shall reduce the time period and/or
Territory to permissible duration or size.

     4.7  Remedies.
          --------

          (a) Employee has carefully considered the nature and extent of the
     restrictions upon him and the rights and remedies conferred upon the
     Company under this Agreement, and Employee hereby acknowledges and agrees
     that such restrictions, rights and remedies are reasonable in time and
     territory, are designed to eliminate competition which otherwise would be
     unfair to the Company, do not stifle the inherent skill and experience of
     Employee, would not operate as a bar to Employee's sole means of support,
     are fully required to protect the legitimate interests of the Company and
     do not confer a benefit upon the Company disproportionate to the detriment
     to Employee.

          (b) Employee acknowledges and agrees that the Restrictive Covenants
     are reasonable and necessary for the protection of the Company's business
     interests, that irreparable injury will result to the Company if Employee
     breaches any of the terms of said Restrictive Covenants, and that in the
     event of Employee's actual or threatened breach of any such Restrictive
     Covenants, the Company will have no adequate remedy at law.  Employee
     accordingly agrees that in the event of any actual or threatened breach by
     him of any of the Restrictive Covenants, the Company shall be entitled,
     upon three days' notice to Employee, to immediate temporary injunctive and
     other equitable relief, without bond and without the necessity of showing
     actual monetary damages, subject to a hearing as soon thereafter as
     possible.  Nothing contained herein shall be construed as prohibiting the
     Company from pursuing any other remedies available to it for such breach or
     threatened breach, including the recovery of any damages which it is able
     to prove.
