     NOW THEREFORE, in consideration of the promises and mutual covenants of the

     Standards set forth in Attachment D-1, Goal Performance Standards to the
     Agreement.

1.3 SECTION 4.3.2, "SERVICE AREA MODIFICATION," is amended by inserting the
following at the end:

     of their respective

<PAGE>

obligations to notify APS of their active Service Areas pursuant to Exhibit 1 to
Attachment D-1, Goal Performance Standards.

1.4 SECTION 4.6, "AVAILABILITY OF IN-NETWORK MHSA SERVICES," is amended by
replacing "24" in paragraph (b) with "48", and by replacing "5" in paragraph (c)

reports due for 1999 and each annual period thereafter shall be due on
February 15." and (b) by inserting at the end of the section:

     If the due date for a report falls on a weekend or holiday, then the report
     shall be due on the next business day. For purposes of the annual report,
     the period reported on shall be the calendar year commencing January 1 and
     ending December 31.

1.6 SECTION 4.8.5, "RATE REDUCTION FOR SUB-STANDARD PERFORMANCE," is hereby
deleted and replaced with the following:

     4.8.5 PENALTY FOR NON-ATTAINMENT OF GOAL PERFORMANCE STANDARD. If, after
     the expiration of the applicable cure period described in Attachment D-1,
     "Goal Performance Standards," APS has failed to attain the Goal Performance
     Standard, then APS shall pay CHC the penalty provided for in Attachment
     D-1. Such payment from APS shall be due within thirty (30) days from the
     end of the applicable cure period. In calculating the amount of the
     penalty, the number of Members shall be based on the number of Members APS
     received Capitation Payments for during the applicable reporting period.
     The penalty shall be calculated from the first day of the cure period until
     the standard has been met by APS.

1.7 SECTION 4.8.6, "PERFORMANCE DEFAULT CAUSED BY MIS," is deleted and replaced
with the following:

     4.8.6 PERFORMANCE DEFAULT BEYOND APS' CONTROL. In the event the operations
     of APS or any substantial portion thereof are interrupted by war, fire,
     insurrection, labor/provider contract troubles, riots, the elements,
     earthquakes, acts of God, or similar circumstance that is beyond APS
     control, the provisions of this Agreement (or such portions hereof as APS
     is thereby rendered incapable of performing), including CHC's obligation to
     compensate APS for any services which APS is incapable of performing, shall
     be suspended for the duration of such interruption. Such suspension shall
     not be deemed or construed as a breach of this Agreement by APS or the
     failure by APS to comply with a Goal Performance Standard.

                        of the date of a proposed borrowing, would not cause the
                        Leverage Ratio of the Holding Company to exceed the
                        maximum Leverage Ratio in effect at such time under
                        Section 7.16, and

                  (C)   the Revolving Credit Commitment then in effect, less the
                        aggregate outstanding principal amount of Acquisition
                        Loans.

                  (ii) Each Working Capital Loan shall be in an aggregate amount
of $100,000 or an integral multiple of $10,000 in excess thereof. No more than
one borrowing of Working Capital Loan shall be made within any week beginning on
Monday of such week and ending on the last Business Day of such week.

            (c) Acquisition Loans shall be available for the purpose of
financing Acquisitions by the Company that are approved by the Agent and the
Required Lenders in their sole good faith discretion, in such amounts and upon
such terms and conditions as the Required Lenders shall approve, and in an
aggregate principal amount not to exceed at any time outstanding in the exercise
of such discretion (the "ACQUISITION AVAILABILITY") the Revolving Credit
Commitment then in effect, less the aggregate outstanding principal amount of
Working Capital Loans; PROVIDED that no Acquisition Loan will be permitted if
the amount of such Acquisition Loan when added to the outstanding Debt of the
Company and which sum is used in calculating the Holding Company's Leverage
Ratio on a pro forma basis as of the proposed date of such borrowing after
giving effect to the proposed Acquisition, would cause the Leverage

                                      -22-

<PAGE>

Ratio of the Holding Company to exceed the maximum Leverage Ratio in effect at
such time under Section 7.16, unless the Company can demonstrate that the
Leverage Ratio calculated on a pro forma basis as of the proposed date of such
borrowing after giving effect to the Acquisition and any adjustments to the
EBITDA of the Target permitted by the Required Lenders in their sole good faith
discretion, does not exceed 3.00 to 1.00.

            (d) Within the foregoing limits, to but excluding (i) the
Availability Termination Date, in the case of Acquisition Loans, and (ii) the
Commitment Termination Date in the case of Working Capital Loans, the Company
may borrow under this Section 3.01, repay or prepay Revolving Credit Loans as
required under Section 3.05(b) or to the extent permitted by Section 3.06, and
reborrow pursuant to this Section 3.01.

            SECTION 3.02. REVOLVING CREDIT NOTES. The Revolving Credit Loans of
each Lender shall be evidenced by a single Revolving Credit Note, substantially
in the form of EXHIBIT A-2 (each such note, a "REVOLVING CREDIT NOTE"), dated
the Closing Date in an aggregate principal amount equal to the amount of such
Lender's Revolving Credit Commitment, duly executed and delivered and payable to
such Lender. Each Lender shall record the date and amount of each Revolving
Credit Loan made by it, whether such Revolving Credit Loan was a Working Capital
Loan or an Acquisition Loan, and the date and amount of each payment of
principal made by the Company with respect thereto, and prior to any transfer of
its Revolving Credit Note shall endorse on Schedule A thereto (or any
continuation thereof) forming a part thereof appropriate notations to evidence
the foregoing information with respect to each such Revolving Credit Loan then
outstanding; PROVIDED that the failure of any Lender to make any such
recordation or endorsement shall not affect the obligations of the Company
hereunder or under the Revolving Credit Notes. Each Lender is hereby irrevocably
authorized by the Company so to endorse its Revolving Credit Note and to attach
to and make a part of its Revolving Credit Note a continuation of any such
schedule as and when required.

            SECTION 3.03. INTEREST ON THE REVOLVING CREDIT LOANS. (a) The
Company shall pay interest on the Revolving Credit Loans to the Lenders monthly
in arrears on the first day of each calendar month immediately succeeding the
month for which such interest accrues, commencing with the first day of the
calendar month following the calendar month in which the Closing Date occurs. In
all cases accrued interest on all of the Revolving Credit Loans shall be payable
by the Company to the Lenders on the Commitment Termination Date. Interest at
the Default Rate shall be payable upon demand by the Lenders. If any interest on
any of the Revolving Credit Loans accrues or remains payable after the
Commitment Termination Date, such interest shall be payable by the Company upon
demand by the Lenders.

                  (b) The Company shall be obligated to pay interest to the
Lenders on the outstanding principal balance of each Revolving Credit Loan from
the date such Revolving Credit Loan is made until such Revolving Credit Loan is
repaid in full. Subject to Section 9.02(b), interest on all Revolving Loans
outstanding during any month shall accrue at a floating rate per annum equal to
the Index Rate PLUS 3.75%.

                                      -23-

<PAGE>

                  (c) Each determination by the Agent of the interest rate
hereunder shall be conclusive and binding for all purposes, absent clear and
convincing evidence to the contrary.

            SECTION 3.04. ADVANCING REVOLVING CREDIT LOANS. (a) Each Working
Capital Loan shall be made on notice by the Company to the Agent, given no later
than 10:00 A.M. (New York time) on the Business Day of the proposed Revolving
Credit Loan. Such notice (each a "NOTICE OF WORKING CAPITAL LOAN") shall be
substantially in the form of EXHIBIT B hereto, shall be duly completed and
executed by an Authorized Signatory, and shall specify therein the requested
date and amount of such Working Capital Loan, and such other information as may
be required by the Agent.

                  (b) Each Acquisition Loan shall be made upon such notice and
upon such terms and conditions as the Agent shall specify at the time.
Notwithstanding the foregoing, no request for an Acquisition Loan pursuant to
this subsection (b) shall be effective until the Agent notifies the Company that
the Agent and the Required Lenders have consented to the proposed Acquisition
after having been provided such information respecting the proposed Acquisition
as the Agent and the Required Lenders shall require and such time to review the
same as the Agent and the Required Lenders shall reasonably deem necessary.

                  (c) Each Notice of Working Capital Loan or notice of a
borrowing pursuant to subsection (b) of this Section (each a "NOTICE OF
REVOLVING CREDIT LOAN") shall be given in writing (by telecopy, telex or cable)
or by telephone and confirmed immediately in writing.

                  (d) Not later than 4:00 p.m. (New York City time) (i) on the
date of the requested borrowing, in the case of a Notice of Working Capital Loan
or (ii) on the date of the borrowing specified by the Agent following receipt of
notice of approval of such Acquisition from the Required Lenders in the case of
any other Notice of Revolving Credit Loan, each Lender shall make available its
ratable share of such borrowing of Loans, in immediately available funds, to the
Company Account.

                  (e) The failure of any Lender to make a Revolving Credit Loan
on such date shall not relieve any other Lender of its obligation, if any,
hereunder to make its Revolving Credit Loan on that date. Neither the Agent nor
any Lender shall be responsible for the failure of any other Person to make any
Revolving Credit Loan hereunder on the date required therefor.

            SECTION 3.05. MANDATORY REPAYMENTS AND PREPAYMENTS. (a) The
Revolving Credit Commitment of each Lender shall terminate at the opening of
business on December 15, 2003 (such date and such earlier date on which the
Revolving Credit Commitments shall terminate pursuant to Section 3.08, Section
8.01 or otherwise, the "COMMITMENT TERMINATION DATE"), and there shall become
due and the Company shall pay on the Commitment Termination Date, the entire
outstanding principal amount of each Revolving Credit Loan, together with
accrued and unpaid interest thereon to but excluding the Commitment Termination
Date.

<PAGE>

            (b) If at any time (i) the aggregate unpaid principal balance of the
Working Capital Loans exceeds the Working Capital Availability, or (ii) the
aggregate unpaid principal balance of the Acquisition Loans exceeds the
Acquisition Availability, then, on the next succeeding Business Day, the Company
shall prepay Working Capital Loans and/or Acquisition Loans in an aggregate
principal amount equal to such excess.

            (c) Commencing on April 1, 2000 (the "AMORTIZATION COMMENCEMENT
DATE") and continuing on each Quarterly Date thereafter, the Company shall repay
the Revolving Credit Loans in equal quarterly installments of principal in an
amount equal to 5.00% of all Acquisition Loans outstanding at the close of
business on the Business Day prior to the Amortization Commencement Date.

            (d) There shall become due and payable, and the Company shall
prepay, on the earlier of (i) the date the audited financial statements for each
Fiscal Year are delivered in accordance with Section 6.01 and (ii) 90 days
following the last day of each Fiscal Year, beginning with the Fiscal Year
ending December 31, 1999, an aggregate principal amount of Revolving Credit
Loans equal to the excess of (x) fifty percent (50%) of the Excess Cash Flow for
such Fiscal Year over (y) the amount of such Excess Cash Flow applied to the
repayment of Term Loans on such date in accordance with Section 2.04(b).

            (e) There shall become due and payable, and the Company shall prepay
promptly upon receipt by any Credit Party of the proceeds of any Asset Sale, an
amount equal to the excess of (x) 100% of the Net Cash Proceeds of such Asset
Sale over (y) the amount of such Net Proceeds applied to repayment of Term Loans
on such date in accordance with Section 2.04(b).

            (f) There shall become due and payable, and the Company shall prepay
promptly upon receipt by any Credit Party of (x) any payment which constitutes
Major Casualty Proceeds or (y) any payment under the Key-Person Life Insurance
Policy, an amount equal to the excess of (x) the amount of such payment over (y)
the amount of such payment applied to the repayment of Terms Loans on such date
in accordance with Section 2.04(b), unless, in the case of Major Casualty
Proceeds only, the Required Lenders shall otherwise direct (in which case the
amount of such payment shall be deposited into the Insurance Account to be held
and applied in accordance with Section 5 of the Company Security Agreement).

            (g) There shall become due and payable, and the Company shall prepay
promptly upon receipt by the Holding Company of the proceeds from the issuance
and sale of Common Stock or other equity securities after the Closing Date, an

payment, an

                                      -25-

amount equal to the excess of (x) 100% of such Capitated Beneficiary Adjustment
payment over (y) the amount of such Capitated Beneficiary Adjustment payment
applied to the repayment of Term Loans on such date in accordance with Section
2.04(b).

            SECTION 3.06. OPTIONAL PREPAYMENTS. The Company may prepay the
Revolving Credit Loans in whole or in part (in minimum principal amounts of
$100,000 or in any larger integral multiple of $10,000, or the total remaining
amount outstanding) upon at least three Business Days' prior irrevocable written
notice to the Lenders, without premium or penalty except as provided in Section
3.08(b). The aggregate principal amount of the Revolving Credit Loans designated
for prepayment in any notice of optional prepayment given pursuant to this
subsection shall become due and payable on the date fixed for prepayment as
specified in such notice.

            SECTION 3.07. APPLICATION OF PAYMENTS. Each payment or prepayment of
less than all the outstanding aggregate principal amount of the Loans shall be
applied PRO RATA to all Loans according to their respective outstanding
principal amounts, and shall be applied to the Class of Loan required under this
Agreement or, if not so required, as directed by the Company. The principal
amount of each payment on the Loans pursuant to Section 3.06 shall be applied to
reduce the remaining payments required by Section 3.05(c) in inverse order of
the maturity thereof. No payment of the principal amount of the Loans pursuant
to Section 3.05(c) or 3.06 shall reduce the amount of any payment required by
Sections 3.05(d) through (h). Each payment of less than all of the outstanding
aggregate principal amount of Revolving Credit Loans of any Class shall be
applied by the Lender receiving such payment, PRO RATA to all Revolving Credit
Loans of such Class held by such Lender according to their respective
outstanding principal amounts.

            SECTION 3.08. REDUCTION OF COMMITMENTS. (a) The Revolving Credit
Commitment shall reduce (i) on the Availability Termination Date to an amount
equal to (x) the Working Capital Commitment, PLUS (y) the amount of the
aggregate outstanding principal amount of Acquisition Loans, and (ii) thereafter
by the amount of each payment made or required to be made pursuant to Section
3.05(c), (d) (e), (f), (g) or (h) or Section 3.06.

      (b) The Company shall have the right at any time to terminate in whole
this Agreement, or from time to time, irrevocably to reduce in part the amount
of the Revolving Credit Commitment upon at least 30 days' prior written notice
to the Agent. Such notice shall be irrevocable on the part of the Company and
shall specify the effective date of such reduction or termination, whether a
termination or reduction is being made, and, in the case of any reduction, the
amount thereof shall be in an amount of Two Million Five Hundred Thousand
Dollars ($2,500,000) or an integral multiple thereof. Upon any such reduction,
the Company shall simultaneously prepay any outstanding Revolving Credit Loans
to the extent necessary so that the aggregate outstanding principal amount of
the Revolving Credit Loans does not exceed the amount of the Revolving Credit
Commitment after giving effect to any partial reduction thereof. The aforesaid
prior notice requirement shall not apply to the Agent's exercise of remedies
under Section 8.01. In the event the Company exercises its rights under this
paragraph to prepay the Revolving Credit Loans and terminate this Agreement or
permanently reduce the Revolving

                                      -26-

<PAGE>

Credit Commitment, the Company agrees that such prepayment shall be accompanied
by (i) the payment by the Company to the Agent for the ratable account of the
Lenders of all accrued and unpaid interest and, in the case of a termination of
this Agreement, all fees and other remaining Obligations hereunder and (ii) if
such reduction or prepayment shall occur prior to the first anniversary of the
Closing Date, the payment of a fee to the Agent for the ratable account of the
Lenders equal to 1.50% multiplied by the amount by which the Revolving Credit
Commitments are permanently reduced by such exercise. The amount of the
Revolving Credit Commitment may not be reinstated if it is reduced or if this
Agreement is terminated by the Company.

            SECTION 3.09. WARRANTS. (a) On the Agreement Date, the Holding
Company shall deliver to NationsCredit, in consideration for executing this
Agreement, warrants exercisable for a number of shares of Common Stock
corresponding to up to 7.00% of the equity of Holding Company on a fully diluted
basis (together with any substitutions or replacements therefor, the
"WARRANTS"), subject to adjustment in accordance with the terms of the Warrants.
The Warrants shall be substantially in the form of EXHIBIT J hereto, and shall
be duly executed and registered in such name or names and in such denominations
as NationsCredit shall have notified the Holding Company. The Warrants shall be
fully earned by NationsCredit by its execution hereof.

            (b) The Holding Company and NationsCredit agree that, for Federal
income tax purposes (i) the Warrants together with the Revolving Credit Loans
and Term Loans constitute an investment unit and (ii) the aggregate issue price
of the Revolving Credit Loans and Term Loans is $________ and the aggregate
purchase price of the Warrants is $_______. Neither of the Holding Company nor
any Lender shall voluntarily take any action inconsistent with the agreement set
forth in the immediately preceding sentence.

connection with the transactions contemplated hereby or by the other Financing
Documents (including (i)(A) as a direct or indirect result of the presence on or
under, or escape, seepage, leakage, spillage, discharge, emission or release
from, any property now or previously owned, leased or operated by the Company or
any of its Subsidiaries of any Hazardous Materials or any Hazardous Materials
Contamination, (B) arising out of or relating to the offsite disposal of any
materials generated or present on any such property or (C) arising out of or
resulting from the environmental condition of any such property or the
applicability of any governmental requirements relating to Hazardous Materials,
whether or not occasioned wholly or in part by any condition, accident or event
caused by any act or omission of the Company or any of its Subsidiaries, and
(ii) proposed and actual extensions of credit under this Agreement) and the use
or intended use of the proceeds of the Notes and the Letters of Credit, except
that the Company shall have no obligation hereunder to an Indemnitee with
respect to any liability resulting solely from the gross negligence or willful
misconduct of such Indemnitee. To the extent that the undertaking set forth in
the immediately preceding sentence may be unenforceable, the Company shall
contribute the maximum portion which it is permitted to pay and satisfy under
applicable law to the payment and satisfaction of all such indemnified
liabilities incurred by the Indemnitees or any of them. Without limiting the
generality of any provision of

                                      -60-

<PAGE>

this Section, to the fullest extent permitted by law, the Company hereby waives
all rights for contribution or any other rights of recovery with respect to
liabilities, losses, damages, costs and expenses arising under or relating to
Environmental Laws that it might have by statute or otherwise against any
Indemnitee; except to the extent that any thereof are finally determined by a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of such Indemnitee.

            SECTION 9.06. TAXES. The Company agrees to pay all governmental
assessments, charges or taxes (except income or other similar taxes imposed on
any Lender or any holder of a Note), including any interest or penalties
thereon, at any time payable or ruled to be payable in respect of the existence,
execution or delivery of this Agreement, the other Financing Documents, or the
issuance of the Notes, and to indemnify and hold each Lender and each and every
holder of the Notes, Warrants or Warrant Shares harmless against liability in
connection with any such assessments, charges or taxes.

            SECTION 9.07. FUNDING LOSSES. If the Company fails to borrow any
Loans after notice has been given to any Lender in accordance with Section 3.04
or make any payment when due (including pursuant to a notice of optional
prepayment), the Company shall reimburse each Lender within 15 days after demand
for any resulting loss or expense incurred by it (or by an existing or
prospective participant in the related Loan), including any loss incurred in
obtaining, liquidating or employing deposits from third parties, but excluding
loss of margin for the period after any such payment or failure to borrow;
PROVIDED that such Lender shall have delivered to the Company a certificate
calculating in reasonable detail the amount of such loss or expense, which
certificate shall be conclusive in the absence of manifest error.

            SECTION 9.08. MAXIMUM INTEREST. (a) In no event shall the interest
charged with respect to the Notes or any other Obligations of the Company or any
Subsidiary under the Financing Documents exceed the maximum amount permitted
under the laws of the State of Georgia or of any other applicable jurisdiction.

            (b) Notwithstanding anything to the contrary herein or elsewhere, if
at any time the rate of interest payable for the account of any Lender hereunder
or under the Notes or any other Financing Document (the "STATED RATE") would
exceed the highest rate of interest permitted under any applicable law to be
charged by such Lender (the "MAXIMUM LAWFUL RATE"), then for so long as the
Maximum Lawful Rate would be so exceeded, the rate of interest payable for the
account of such Lender shall be equal to the Maximum Lawful Rate; PROVIDED, that
if at any time thereafter the Stated Rate is less than the Maximum Lawful Rate,
the Company shall, to the extent permitted by law, continue to pay interest for
the account of such Lender at the Maximum Lawful Rate until such time as the
total interest received by such Lender is equal to the total interest which such
Lender would have received had the Stated Rate been (but for the operation of
this provision) the interest rate payable. Thereafter, the interest rate payable
for the account of such Lender shall be the Stated Rate unless and until the
Stated Rate again would exceed the Maximum Lawful Rate, in which event this
provision shall again apply.

                                      -61-

<PAGE>

            (c) In no event shall the total interest received by any Lender
exceed the amount which such Lender could lawfully have received had the
interest been calculated for the full term hereof at the Maximum Lawful Rate
with respect to such Lender.

            (d) In computing interest payable with reference to the Maximum
Lawful Rate applicable to any Lender, such interest shall be calculated at a
daily rate equal to the Maximum Lawful Rate divided by the number of days in the
year in which such calculation is made.

            (e) If any Lender has received interest hereunder in excess of the
Maximum Lawful Rate with respect to such Lender, such excess amount shall be
applied to the reduction of the principal balance of its Loans or to other
amounts (other than interest) payable hereunder, and if no such principal or
other amounts are then outstanding, such excess or part thereof remaining shall
be paid to the Company.

                                    ARTICLE X

                                    THE AGENT

            SECTION 10.01. APPOINTMENT AND AUTHORIZATION. Each Lender
irrevocably appoints and authorizes the Agent to enter into each of the Security
Documents on its behalf and to take such action as agent on its behalf and to
exercise such powers under the Financing Documents as are delegated to the Agent
by the terms thereof, together with all such powers as are reasonably incidental
thereto.

            SECTION 10.02. AGENT AND AFFILIATES. NationsCredit shall have the
same rights and powers under the Financing Documents as any other Lender and may
exercise or refrain from exercising the same as though it were not the Agent,

any kind of business with the Company or any Subsidiary or affiliate of the
Company as if it were not the Agent hereunder.

            SECTION 10.03. ACTION BY AGENT. The obligations of the Agent
hereunder are only those expressly set forth herein and under the other
Financing Documents. Without limiting the generality of the foregoing, the Agent
shall not be required to take any action with respect to any Default, except as
expressly provided in Article VIII.

            SECTION 10.04. CONSULTATION WITH EXPERTS. The Agent may consult with
legal counsel (who may be counsel for the Company), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

            SECTION 10.05. LIABILITY OF AGENT. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
not taken by it in connection with the Financing Documents (i) with the consent
or at the request of the Required Lenders or (ii) in the absence of its own
gross negligence or willful misconduct. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to

                                      -62-

<PAGE>

ascertain, inquire into or verify (i) any statement, warranty or representation
made in connection with any Financing Document or any borrowing hereunder; (ii)
the performance or observance of any of the covenants or agreements of the
Company; (iii) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered to the Agent; or (iv) the validity,
effectiveness, sufficiency or genuineness of any Financing Document or any other
instrument or writing furnished in connection therewith. The Agent shall not
incur any liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing (which may be a bank wire, telex, facsimile
transmission or similar writing) believed by it to be genuine or to be signed by
the proper party or parties.

            SECTION 10.06. INDEMNIFICATION. Each Lender shall, ratably in
accordance with its Revolving Credit Commitment (whether or not the Revolving
Credit Commitments have been terminated), indemnify the Agent (to the extent not
reimbursed by the Company) against any cost, expense (including 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 the Financing Documents or any action taken
or omitted by the Agent hereunder or thereunder.

            SECTION 10.07. CREDIT DECISION. Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under the Financing Documents.

            SECTION 10.08. SUCCESSOR AGENT. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Company. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor
Agent which, absent the occurrence and continuance of a Default, must be
reasonably acceptable to the Company. If no successor Agent shall have been so
appointed by the Required Lenders, and shall have accepted such appointment,
within 30 days after the retiring Agent gives notice of resignation, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which
shall be an institution organized or licensed under the laws of the United
States of America or of any State thereof. Upon the acceptance of its
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent.

            SECTION 11.01. SURVIVAL. All agreements, representations and
warranties made herein shall survive the execution and delivery of this
Agreement and the other Financing Documents and the execution, sale and delivery
of the Notes. The indemnities and agreements set forth in Articles VIII and IX
shall survive the payment of the Notes and the termination of this Agreement.

            SECTION 11.02. NO WAIVERS. No failure or delay by the Agent or any
Lender in exercising any right, power or privilege under any Financing Document
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein and therein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

            SECTION 11.03. NOTICES. All notices, requests and other
communications to any party hereunder shall be in writing (including prepaid

Lender after the date hereof, in a notice delivered to the Company and the Agent
by the assignee Lender forthwith upon such assignment) or at such other address
or telecopy or telex number as such party may hereafter specify for the purpose

under this Agreement or the Notes or any other Financing Document shall be
invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

            SECTION 11.05. AMENDMENTS AND WAIVERS. Any provision of this
Agreement or the Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Company and the Required Lenders
(and, if the rights or duties of the Agent are affected thereby, by the Agent);
PROVIDED that no such amendment or waiver shall, unless signed by all the
Lenders, (i) increase or decrease any Revolving Credit Commitment of any Lender
(except for a ratable decrease in the Revolving Credit Commitments of all
Lenders) or subject any Lender to any additional obligation, (ii) reduce the
principal of or rate of interest on any Loan or fees hereunder, (iii) postpone

other provision of this Agreement.

            SECTION 11.06. SUCCESSORS AND ASSIGNS; REGISTRATION. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns (including any
transferee of any Note or Warrant), except that the Company may not assign or
otherwise transfer any of its rights under this Agreement without the prior
written consent of all Lenders.

            (b) The terms and provisions of this Agreement shall inure to the
benefit of any transferee or assignee of any Note or Warrant and, in the event
of such transfer or assignment, the rights and privileges herein conferred upon
the assigning Lender shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions hereof. Any
assignment shall be for an equal percentage of each Class of such assignor
Lender's Loans and its Revolving Credit Commitment, and any such assignee Lender
shall, upon its registration in the Note Register referred to below, become a
"Lender" for all purposes hereunder. Upon any such assignment, the assignor
Lender shall be released from its Revolving Credit Commitment to the extent
assigned to and assumed by the assignee Lender.

            (c) Upon any assignment of any Note(s), the assigning Lender shall
surrender its Note(s) to the Company for exchange or registration of transfer,
and the Company will promptly execute and deliver in exchange therefor a new
Note or Note(s) of the same tenor and registered in the name of the assignor
Lender (if less than all of such Lender's Notes are assigned) and the name of
the assignee Lender.

            (d) The Company shall maintain a register (the "NOTE REGISTER") of
the Lenders and all assignee Lenders that are the holders of all the Notes
issued pursuant to this Agreement. The Company will allow any Lender to inspect
and copy such list at the Company's principal place of business during normal
business hours. Prior to the due presentment for registration of transfer of any
Note, the Company may deem and treat the Person in whose name a Note is
registered as the absolute owner of such Note for the purpose of receiving
payment of principal of and premium and interest on such Note and for all other
purposes whatsoever, and the Company shall not be affected by notice to the
contrary.

            (e) Each Lender (including any assignee Lender at the time of such
assignment) represents that it (i) is acquiring its Note solely for investment
purposes and not with a view toward, or for sale in connection with, any
distribution thereof, (ii) has received and reviewed such information as it
deems necessary to evaluate the merits and risks of its investment in the Note,
(iii) is an "accredited investor" within the meaning of Rule 501(a) under the
Securities Act and (iv) has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of its
investment in the Note, including a complete loss of its investment.

                                      -65-

<PAGE>

            (f) Each Lender understands that the Note is being offered only in a
transaction not involving any public offering within the meaning of the
Securities Act, and that, if in the future such Lender decides to resell, pledge
or otherwise transfer the Note, the Note may be resold, pledged or transferred
only (i) to the Company, (ii) to a person who such Lender reasonably believes is
a qualified institutional buyer that purchases for its own account or for the
account of a qualified institutional buyer to whom notice is given that such
resale, pledge or transfer is being made in reliance on Rule 144A under the
Securities Act or (iii) pursuant to an exemption from registration under the
Securities Act.

            (g) Each Lender understands that the Note will, unless otherwise
agreed by the Company and the holder thereof, bear a legend to the following
effect:

      THIS SECURITY IS NOT BEING REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
      AMENDED (THE "SECURITIES ACT"). THE HOLDER HEREOF, BY PURCHASING THIS
      SECURITY, AGREES FOR THE BENEFIT OF THE ISSUER THAT THIS SECURITY MAY BE
      RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) TO THE COMPANY, (2) TO
