        SECTION 2.1. TERMS.

                (a) The maximum aggregate principal amount of credit extended by
Lender to Borrower under this Agreement (the "Loan") that will be outstanding at
any time is Ten Million and No/100 Dollars ($10,000,000.00) (the "Maximum Loan
Amount").

credit, and shall include sums advanced and other credit extended by Lender to
or for the benefit of Borrower from time to time under this Article II (each a

<PAGE>   8

Borrowing Base, the requests of Borrower pursuant to the terms and conditions of
Section 2.2, and on such other basis as Lender may reasonably determine. The
outstanding principal balance of the Loan may fluctuate from time to time, be
reduced by repayments made by Borrower (which may be made without penalty or
premium) and be increased by future Revolving Credit Loans, advances and other
extensions of credit to or for the benefit of Borrower, and shall be due and
payable in full upon the expiration of the Term. For purposes of this Agreement,
any determination as to whether there is availability within the Borrowing Base
for advances or extensions of credit shall be made by Lender in its sole
discretion and is final and binding upon Borrower.

                (c) At Closing, Borrower shall execute and deliver to Lender a
promissory note evidencing Borrower's unconditional obligation to repay Lender
for Revolving Credit Loans, advances, and other extensions of credit made under
the Loan, in the form of Exhibit A to this Agreement (as amended, modified,
increased, restated or replaced from time to time, the "Note"), dated the date
of this Agreement, payable to the order of Lender in accordance with the terms
thereof. The Note shall bear interest on the outstanding principal balance of
the Note from the date of the Note until repaid, with interest payable monthly
in arrears on the first Business Day of each month, at a rate per annum (on the
basis of the actual number of days elapsed over a year of 360 days) equal to the
Base Rate, provided that after the occurrence and during the continuance of an
Event of Default such rate shall be equal to the Default Rate. Each Revolving
Credit Loan, advance and other extension of credit shall be deemed evidenced by
the Note, which is deemed incorporated into and made a part of this Agreement by
this reference.

                (d) Subject to the terms and conditions of this Agreement,
advances under the Loan shall be made against a borrowing base equal to
eighty-five percent (85%) of Qualified Accounts due and owing from any
Medicaid/Medicare Account Debtor, Insurer or other Account Debtor (the
"Borrowing Base"). Lender, in its sole credit judgment, may further adjust the
Borrowing Base by applying percentages (known as "liquidity factors") to
Qualified Accounts by payor class based upon Borrower's actual recent collection
history for each such payor class (i.e., Medicare, Medicaid, commercial
insurance, etc.) in a manner consistent with Lender's underwriting practices and
procedures; provided that, (i) at Closing the initial liquidity factor to be
applied to the Borrowing Base shall be seventy percent (70%) and (ii) Lender
agrees to perform an audit within three (3) months of the initial Closing
hereunder, at which time such liquidity factor may be adjusted, in Lender's sole
discretion, based on the results of such audit; and provided further that Lender
shall apply a second liquidity factor to the Unbilled Accounts equal to
seventy-five percent (75%). Such liquidity factors may be adjusted by Lender
throughout the Term as warranted by Lender's underwriting practices and
procedures and using its sole credit judgment.

        SECTION 2.2. LOAN ADMINISTRATION. Borrowings under the Loan shall be as
follows:

                (a) A request for a Revolving Credit Loan shall be made, or

Lender notice of its intention to borrow, in which notice Borrower shall specify
the amount of the proposed borrowing and the proposed borrowing date, not later
than noon Eastern time on the proposed borrowing date by telephone (which
telephonic notice shall be promptly confirmed by Borrower in writing); provided,
however, that no such request may be made at a time when there exists an Event
of Default; and (ii) the becoming due of any amount required to be paid under
this Agreement, whether as interest or for any other Obligation, shall be deemed
irrevocably to be a request for a Revolving Credit Loan on the day following the
due date in the amount required to pay such interest or other Obligation if such
was not paid by Borrower on the due date.

                (b) Borrower hereby irrevocably authorizes Lender to disburse
the proceeds of each Revolving Credit Loan requested, or deemed to be requested,
as follows: (i) the proceeds of each Revolving Credit Loan requested under

account as may be agreed upon by Borrower and Lender from time to time or

all payments made by Borrower on any Obligations and all proceeds of Collateral
which are indefeasibly paid to Lender, and may record therein, in accordance
with customary accounting practice, other debits and credits, including interest
and all charges and expenses properly chargeable to Borrower. All collections
into the Concentration Account pursuant to Section 2.3 shall be applied first to
fees, costs and expenses due and owing under the Loan Documents, then to
interest due and owing under the Loan Documents, and then to principal
outstanding with respect to Revolving Credit Loans.

                (e) Lender will account to Borrower monthly with a statement of
Revolving Credit Loans, charges and payments made pursuant to this Agreement,
and such accounting rendered by Lender shall be deemed final, binding and
conclusive upon Borrower, absent manifest error, unless Lender is notified by
Borrower in writing to the contrary within thirty (30) days of the date each
accounting is mailed to Borrower. Such notice shall be deemed an objection to
those items specifically objected to in the notice.

        SECTION 2.3. COLLECTIONS, DISBURSEMENTS, BORROWING AVAILABILITY, AND
LOCKBOX ACCOUNT.

                (a) Borrower shall establish and maintain a lockbox (the
"Lockbox") and a lockbox account (the "Lockbox Account") with National City
Bank, MI/IL (the "Lockbox Bank"), subject to the provisions of this Agreement,
and shall execute with the Lockbox Bank a lockbox agreement in the form attached
as Exhibit B-1, and such other agreements related to such lockbox agreement as
Lender may reasonably require. Borrower shall ensure that all collections of
Accounts from Medicaid/Medicare Account Debtors only are paid directly by such
Medicaid/Medicare Account Debtors into such Lockbox established pursuant to this
subsection (a) for deposit into the Lockbox Account established pursuant to this
subsection (a), and that all funds deposited into such Lockbox Account are
immediately transferred into a depository account maintained by Lender at Bank
One, N.A., or such other financial institution as determined by Lender in its
sole discretion, by written notice to Borrower and the Lockbox Bank (the
"Concentration Account").

                (b) Borrower shall establish and maintain a second lockbox (also
referred to herein as the "Lockbox") with the Lockbox Bank in Borrower's name,
subject to the provisions of this Agreement. Lender shall establish and maintain
a second lockbox account with the Lockbox Bank (also referred to herein as the
"Lockbox Account"), and Borrower shall execute with the Lockbox Bank a second
lockbox agreement in the form attached as Exhibit B-2, and such other agreements
related to such lockbox agreement as Lender may reasonably require.
Notwithstanding the provisions of Section 2.3(a), Borrower shall ensure that all
collections of Accounts due from Account Debtors other than Medicaid/Medicare
Account Debtors are paid directly by such Account Debtors into such Lockbox
established pursuant to this subsection (b) for deposit into the Lockbox Account
established pursuant to this subsection (b), and that all funds deposited into
such Lockbox Account are immediately transferred into the Concentration Account.

                (c) Notwithstanding anything in any lockbox agreement to the
contrary, Borrower agrees that it shall be liable for any fees and charges in
effect from time to time and charged by the Lockbox Bank in connection with the
Lockbox and the Lockbox Account, and that Lender shall have no liability
therefor. Borrower further acknowledges and agrees that, to the extent such fees
and charges are not paid by Borrower directly but are satisfied using
collections in the Lockbox Account, such fees and charges shall be deemed to be
Revolving Credit Loans made by Lender hereunder and, to the extent that the
payment of such fees or charges by Borrower as provided herein results in any
overadvance under this Agreement, Borrower agrees to immediately (upon notice)
repay to Lender the amount of such overadvance. Lender acknowledges that
Borrower is entitled to all interest accrued on amounts in the Lockbox Account.
Borrower agrees to indemnify and hold Lender harmless from any

                                       8
<PAGE>   10

and all liabilities, claims, losses and demands whatsoever, including reasonable
attorney's fees and expenses, arising from or relating to actions of Lender or
the Lockbox Bank pursuant to this Section 2.3 or any lockbox agreement.

                (d) Lender shall apply, on a daily basis, all funds transferred
into the Concentration Account pursuant to this Section 2.3 to reduce the
outstanding indebtedness under the Loan (in accordance with Section 2.2(d)), and
all future Revolving Credit Loans, advances and other extensions of credit to be
made by Lender under the conditions set forth in this Article II. To the extent
that any collections of Accounts or proceeds of other Collateral are not sent
directly to the Lockbox as required by this Section 2.3 but are received by
Borrower, such collections shall be held in trust for the benefit of Lender and
immediately remitted, in the form received, to the Lockbox Bank for transfer to
the Concentration Account immediately upon receipt by Borrower.

                (e) Borrower acknowledges and agrees that its compliance with
the terms of this Section 2.3 is essential, and that Lender will suffer
immediate and irreparable injury and have no adequate remedy at law, if
Borrower, through its acts or omissions, causes or permits Account Debtors to
send payments other than to the Lockbox, or if Borrower fails to immediately
deposit collections of Accounts or proceeds of other Collateral in the Lockbox
Account as herein required. Upon Borrower's failure to comply with the terms of
this Section 2.3, Lender will be entitled, in addition to exercising any other
rights and remedies available to it, to assess a non-compliance fee which shall
operate to increase the Base Rate by two percent (2%) per annum during any
period of non-compliance; provided, that such non-compliance fee shall not be
charged with respect to any non-compliance by Borrower hereunder that
constitutes an Event of Default for which Lender has exercised its right to
charge the Default Rate.

                (f) All funds transferred from the Concentration Account for
application to Borrower's indebtedness to Lender shall be applied to reduce the
Loan balance, but for purposes of calculating interest shall be subject to a
four (4) Business Day clearance period. If as the result of collections of
Accounts pursuant to the terms and conditions of this Section 2.3 a credit
balance exists with respect to the Concentration Account, such credit balance
shall not accrue interest in favor of Borrower, but shall be available to
Borrower at any time or times for so long as no Event of Default, and no fact,
event or circumstance that, with notice or the passage of time (or both), would
constitute an Event of Default, exists.

        SECTION 2.4. FEES.

                (a) By executing this Agreement, Borrower agrees unconditionally
to pay to Lender a commitment fee equal to one percent (1 %) of the Maximum Loan
Amount (the "Commitment Fee").

                (b) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a monthly usage fee (the "Usage Fee") equal
to 0.0425% of the average amount by which the Maximum Loan Amount exceeds the
average amount of the outstanding principal balance of the Revolving Credit
Loans during the preceding month. The Usage Fee shall be payable monthly in
arrears on the first Business Day of each successive calendar month.

                (c) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a monthly loan management fee (the "Loan
Management Fee") equal to one twelfth of one percent (0.083%) of the average
amount of the outstanding principal balance of the Revolving Credit Loans during
the preceding month. The Loan Management Fee shall be payable monthly in arrears
on the first Business Day of each successive calendar month.

                (d) Subject to the provisions of this Section 2.4(d), Borrower
shall pay to or reimburse Lender for, as the case may be, any and all
out-of-pocket fees incurred by Lender in connection with up to one (1) audit per
calendar quarter of Borrower's books and records; provided, that for purposes
hereof, "audit" shall not include any reconciliation or other activities
performed by Lender pursuant to the Intercreditor Agreement (as defined). All
amounts to be paid or reimbursed by Borrower hereunder shall be due and payable
on the first

                                       9
<PAGE>   11

Business Day of the month following the date of issuance by Lender of a request
for payment or reimbursement thereof to Borrower; provided, however, that on the
occurrence and during the continuance of any Event of Default under this
Agreement or any of the other Loan Documents, the foregoing limitation on the
number of audits to be paid for or reimbursed by Borrower shall not apply, and
(i) Borrower shall be required to pay or reimburse Lender for any and all fees
described in this Section 2.4(d) that are incurred by Lender in connection with
any audits conducted by Lender during such period, without regard to the
foregoing cap on such fees, and (ii) any audits conducted Lender during such
period shall not be applied towards the number of audits for which Borrower is
required to pay or reimburse Lender as provided herein. Notwithstanding anything
in this Section 2.4(d) to the contrary, Lender shall not be limited in the
number of any audits or other similar actions conducted or permitted to be
conducted by it under this Agreement.

                (e) Borrower shall pay to Lender, on demand, any and all
customary fees, costs or expenses which Lender or any participant pays to a bank
or other similar institution (including, without limitation, any fees paid by
Lender to any participant) arising out of or in connection with (i) the
forwarding to Borrower or any other Person on behalf of Borrower, by Lender, of
proceeds of Revolving Credit Loans made by Lender to Borrower pursuant to this
Agreement, and (ii) the depositing for collection, by Lender or any participant,
of any check or item of payment received or delivered to Lender or any
participant on account of Obligations.

        SECTION 2.5. PAYMENTS. Principal payable on account of Revolving Credit
Loans shall be payable by Borrower to Lender immediately upon the earliest of
(a) the receipt by Borrower or Lender of any payments on or proceeds from any of
the Collateral, to the extent of such proceeds, (b) the occurrence of an Event
of Default if the Loan and the maturity of the payment of the Obligations are
accelerated, or (c) the termination of this Agreement pursuant to Section 2.8 of
this Agreement; provided, however, that if the outstanding principal balance of
the Revolving Credit Loans is at any time in excess of the Borrowing Base,
Borrower shall, immediately upon demand, repay such excess. Interest accrued on
the Revolving Credit Loans shall be due on the earliest of (x) the first
Business Day of each month (for the immediately preceding month), computed on
the last calendar day of the preceding month, (y) the occurrence of an Event of
Default if the Loan and the maturity of the payment of the Obligations are
accelerated, or (z) the termination of this Agreement pursuant to Section 2.8.
Except to the extent otherwise set forth in this Agreement, all payments of
principal and of interest on the Loan, all other charges and any other
obligations of Borrower under this Agreement, shall be made to Lender to the
Concentration Account, in immediately available funds. All payments shall be
made without deduction for any set-off, recoupment, counterclaim or defense that
Borrower now has or may have in the future.

        SECTION 2.6. USE OF PROCEEDS. The proceeds of Lender's advances under
the Loan shall be used solely for working capital and for other costs of
Borrower arising in the ordinary course of Borrower's business.

        SECTION 2.7. INTEREST RATE LIMITATION. The parties intend to conform
strictly to the applicable usury laws in effect from time to time during the
term of the Loan. Accordingly, if any transaction contemplated by this Agreement
would be usurious under such laws, then notwithstanding any other provision of
this Agreement: (a) the aggregate of all interest that is contracted for,
charged, or received under this Agreement or under any other Loan Document shall
not exceed the maximum amount of interest allowed by applicable law (the
"Highest Lawful Rate"), and any excess shall be promptly credited to Borrower by
Lender (or, to the extent that such consideration shall have been paid, such
excess shall be promptly refunded to Borrower by Lender); (b) neither Borrower
nor any other Person now or hereafter liable under this Agreement shall be
obligated to pay the amount of such interest to the extent that it is in excess
of the Highest Lawful Rate; and (c) the effective rate of interest shall be
reduced to the Highest Lawful Rate. All sums paid, or agreed to be paid, to
Lender for the use, forbearance, and detention of the debt of Borrower to Lender
shall, to the extent permitted by applicable law, be allocated throughout the
full term of the Note until payment is made in full so that the actual rate of
interest does not exceed the Highest Lawful Rate in effect at any particular
time during the full term thereof. If at any time the rate of interest under the
Note exceeds the Highest Lawful Rate, the rate of interest to accrue pursuant to
this Agreement shall be limited, notwithstanding anything to the contrary in
this Agreement, to the Highest Lawful Rate, but any subsequent reductions in the
Base

                                       10
<PAGE>   12

Rate shall not reduce the interest to accrue pursuant to this Agreement below
the Highest Lawful Rate until the total amount of interest accrued equals the
amount of interest that would have accrued if a varying rate per annum equal to
the interest rate under the Note had at all times been in effect.

        SECTION 2.8. TERM.

                (a) Subject to Lender's right to cease making Revolving Credit
Loans to Borrower upon or after any Event of Default, this Agreement shall be in
effect for a period of two (2) years from the Closing Date, unless terminated as
provided in this Section 2.8 (the "Term"), and this Agreement shall be renewed
for one (1) year periods thereafter upon the mutual written agreement of the
parties.

                (b) Notwithstanding anything in this Agreement to the contrary,
Lender may terminate this Agreement without notice upon or after the occurrence
of an Event of Default.

                (c) Upon at least thirty (30) days prior written notice to
Lender (the "Termination Notice Period"), Borrower may terminate this Agreement
prior to the expiration of the Term (as provided in Section 2.8(a)).

                (d) All of the Obligations shall be immediately due and payable
upon the termination date stated in any notice of termination of this Agreement
delivered pursuant to Section 2.8(c) (the "Termination Date"); provided that,
notwithstanding anything in Section 2.8(c) to the contrary, the Termination Date
shall be effective no earlier than the first Business Day of the month following
the expiration of the Termination Notice Period. All undertakings, agreements,
covenants, warranties, and representations of Borrower contained in the Loan
Documents shall survive any such termination and Lender shall retain its Liens
in the Collateral and all of its rights and remedies under the Loan Documents
notwithstanding such termination until Borrower has paid the Obligations to
Lender, in full, in immediately available funds. At the effective date of any
termination of this Agreement other than upon expiration of the Term (whether by
voluntary termination by Borrower or by termination by Lender following the
occurrence of an Event of Default), Borrower shall pay to Lender (in addition to
the then outstanding principal, accrued interest and other Obligations owing
under the terms of this Agreement and any other Loan Documents) as yield
maintenance for the loss of bargain and not as a penalty, an amount equal to the
applicable Termination Fee.

                (e) Notwithstanding any provision of this Agreement which makes
reference to the continuance of an Event of Default, nothing in this Agreement
shall be construed to permit Borrower to cure an Event of Default following the
lapse of the applicable cure period, and Borrower shall have no such right in
any instance unless specifically granted in writing by Lender.

        SECTION 2.9. INTENTIONALLY LEFT BLANK.

                                   ARTICLE III

                                   COLLATERAL

Lien described in Section 1.45 that may, by operation of law, have priority over
Lender's first priority Lien hereunder) on and security interest in, upon, and

together with all cash and non-cash proceeds and products thereof;

                (j) all of Borrower's now owned or hereafter acquired machinery,

                (k) to the extent not listed above as original collateral, the

        SECTION 3.2. LIEN DOCUMENTS. At Closing and thereafter as Lender deems
necessary in its sole discretion, Borrower shall execute and deliver to Lender,
or have executed and delivered (all in form and substance satisfactory to Lender
in its sole discretion) any agreements, documents, instruments, and writings
deemed necessary by Lender or as Lender may otherwise request from time to time
in its sole discretion to evidence, perfect, or protect Lender's Lien and
security interest in the Collateral required under this Agreement. Borrower
hereby authorizes Lender to file one or more financing statements and amendments
thereto describing the Collateral and describing any agricultural liens or other
statutory liens held by Lender.

        SECTION 3.3. COLLATERAL ADMINISTRATION.

                (a) All Collateral (except deposit accounts) shall at all times
be kept by Borrower at its principal office(s) as set forth on Schedule 4.15 and
shall not be moved from such locations without (i) providing prior written
notice to Lender in accordance with Section 6.15, and (ii) obtaining the prior
written consent of Lender, which consent shall not be unreasonably withheld.

                (b) Borrower shall keep accurate and complete records of its
Accounts and all payments and collections thereon and shall submit to Lender on
such periodic basis as Lender shall request a sales and collections report for
the preceding period, in form satisfactory to Lender. In addition, if Accounts
in an aggregate face amount in excess of $50,000.00 become ineligible because
they fall within one of the specified categories of ineligibility set forth in
the definition of Qualified Accounts or otherwise, Borrower shall notify Lender
of such occurrence within five (5) Business Days following such occurrence and
the Borrowing Base shall thereupon be adjusted to reflect such occurrence. If
requested by Lender, Borrower shall execute and deliver to Lender formal written
assignments of all of its Accounts weekly or daily, which shall include all
Accounts that have been created since the date of the last assignment, together
with copies of claims, invoices or other information related thereto.

                (c) Whether or not an Event of Default has occurred, any of
Lender's officers, employees or agents shall have the right, at any time or
times hereafter, in the name of Lender or any designee of Lender or Borrower, to
verify the validity, amount or any other matter relating to any Accounts by
mail, telephone, telegraph or otherwise. Borrower shall cooperate fully with
Lender in an effort to facilitate and promptly conclude such verification
process.

                (d) To expedite collection, Borrower shall endeavor in the first
instance to make collection of its Accounts for Lender. Lender shall have the
right at any time to notify Account Debtors (subject to applicable law regarding
Medicaid/Medicare Account Debtors) that Accounts have been assigned to Lender.

                                       13
<PAGE>   15

                (e) As between Borrower and Lender, Borrower shall bear the risk
of loss on all Collateral, regardless of whether such Collateral is in the
possession or control of Borrower, Lender, a bailee or any other Person,
provided that Lender agrees to treat any Collateral in its possession in a
commercially reasonable manner.

        SECTION 3.4. OTHER ACTIONS. In addition to the foregoing, Borrower:

                (a) shall provide prompt written notice to each private
indemnity, managed care or other Insurer who either is currently an Account
Debtor or becomes an Account Debtor at any time following the date of this
Agreement that Lender has been granted a first priority Lien and security
interest in, upon and to all Accounts applicable to such Insurer and directs
each Account Debtor to make payments into the Lockbox, and hereby authorizes
Lender, upon Borrower's failure to send such notices within ten (10) days after
the date of this Agreement (or ten (10) days after the Insurer becomes an
Account Debtor), to send any and all similar notices to such Insurers;

                (b) shall do and hereby authorizes Lender to do anything further
that may be lawfully required by Lender to secure Lender and effectuate the
intentions and objects of this Agreement, including but not limited to the
execution and delivery of lockbox agreements, continuation statements,
amendments to financing statements, and any other documents required under this
Agreement;

                (c) at Lender's request, shall immediately deliver to Lender all
items for which Lender must receive possession to obtain a perfected security
interest;

                (d) shall, on Lender's demand, deliver to Lender all notes,
certificates, and documents of title, chattel paper, warehouse receipts,
instruments, and any other similar instruments constituting Collateral;

                (e) shall, where Collateral is in the possession of a third
party, join with Lender in notifying the third party of Lender's security
interests and obtaining an acknowledgement from the third party that it is
holding the Collateral for the benefit of Lender;

                (f) shall cooperate with Lender in obtaining control with
respect to Collateral consisting of deposit accounts, investment property,
letter of credit rights, electronic chattel paper and any other portion of the
Collateral for which control is required in order to perfect a security
interest; and

                (g) shall not create any chattel paper without placing a legend
on the chattel paper acceptable to Lender indicating that Lender has a security
interest in the chattel paper.

        SECTION 3.5. SEARCHES. Before Closing, and thereafter (as and when
determined by Lender in its sole discretion), Lender will perform the searches
described in clauses (a), (b) and (c) below against Borrower (the results of
which are to be consistent with Borrower's representations and warranties under
this Agreement), all at Borrower's expense:

                (a) Uniform Commercial Code searches with the Secretary of State
and local filing offices of each jurisdiction where Borrower maintains its
executive offices, a place of business, or assets and the jurisdiction in which
the Borrower is organized;

                (b) judgment, federal tax lien and corporate and partnership tax
lien searches, in each jurisdiction searched under clause (a) above; and

                (c) searches of applicable corporate, limited liability company,
partnership and related records to confirm the continued existence, organization
and good standing of Borrower and the exact legal name under which Borrower is
organized.

                                       14
<PAGE>   16

        SECTION 3.6. POWER OF ATTORNEY. Each of the officers of Lender is hereby
irrevocably made, constituted and appointed the true and lawful attorney for
Borrower (without requiring any of them to act as such) with full power of
substitution to do the following: (a) endorse the name of Borrower upon any and
all checks, drafts, money orders, and other instruments for the payment of money
that are payable to Borrower and constitute collections on Borrower's Accounts;
(b) execute in the name of Borrower any financing statements, schedules,
assignments, instruments, documents, and statements that Borrower is obligated
to give Lender under this Agreement; (c) take any action Borrower is required to
take under Section 3.4 above; and (d) do such other and further acts and deeds
in the name of Borrower that Lender may deem necessary or desirable to enforce
any Account or other Collateral or perfect Lender's security interest or Lien in
any Collateral. In addition, if Borrower breaches its obligation to direct
payments of the proceeds of the Collateral to the Lockbox Account, Lender, as
the irrevocably made, constituted and appointed true and lawful attorney for
Borrower pursuant to this paragraph, may, by the signature or other act of any
of Lender's officers (without requiring any of them to do so), direct any
federal, state or private payor or fiscal intermediary to pay proceeds of the
Collateral to Borrower by directing payment to the Lockbox Account.

notice or lapse of time, or both, could become an Event of Default, has occurred
and is continuing.

Document nor any other agreement, document, certificate, or statement furnished

contemplated by this Agreement contains any untrue statement of material fact or

future, subject to any offset, Lien, deduction, defense, dispute, counterclaim
or any other adverse condition, and each such Account is absolutely owing to
Borrower and is not contingent in any respect or for any reason;

                (e) there are no facts, events or occurrences which in any way

(including contingent debts), (b) was and is able to pay all of its Indebtedness
as such Indebtedness matures, and (c) had and has capital sufficient to carry on
its business and transactions and all business and transactions in which it

board or agency in connection with the Medicare or Medicaid programs, and to the
knowledge of Borrower, no such reviews are scheduled, pending or threatened
against or affecting any of the providers, or the Collateral, or the
consummation of the transactions contemplated hereby.

        SECTION 4.27. COMPLIANCE WITH HEALTH CARE LAWS. Without limiting the
generality of Section 4.13 or any other representation or warranty made herein,

Laws")). Borrower has maintained in all material respects all records required
to be maintained by the Joint Commission on Accreditation of Healthcare
Organizations, the Food and Drug Administration, Drug Enforcement Agency and
State Boards of Pharmacy and the federal and state Medicare and Medicaid
programs as required by the Healthcare Laws and, to the knowledge of Borrower,

Affiliates and the owners of the facilities and other businesses managed by the
Borrower or its Affiliates have such permits, licenses, franchises, certificates
and other approvals or authorizations of governmental or regulatory authorities
as are necessary under applicable law to own their respective properties and to
conduct their respective business (including without limitation such permits as
are required under such federal, state and other health care laws, and under
such HMO or similar licensure laws and such insurance laws and regulations, as
are applicable thereto), and with respect to those facilities and other
businesses that participate in Medicare and/or Medicaid, to receive
reimbursement under Medicare and Medicaid. To Borrower's knowledge, there
currently exist no restrictions, deficiencies, required plans of correction
actions or other such remedial measures with respect to federal and state
Medicare and Medicaid certifications or licensure.

inventories, reviews, analyses and/or assessments (including any necessary risk
assessments) of all areas of its business and operations required by HIPAA

<PAGE>   22

Borrower to be HIPAA Compliant (as defined below); (ii) has developed or will
promptly develop a detailed plan and time line for becoming HIPAA Compliant (a
"HIPAA Compliance Plan"); and (iii) has implemented or will implement those
provisions of such HIPAA Compliance Plan in all material respects necessary to
ensure that Borrower is or becomes HIPAA Compliant. For purposes hereof, "HIPAA
Compliant" shall mean that Borrower (x) is or will be in compliance with each of
the applicable requirements of the so-called "Administrative Simplification"
provisions of HIPAA on and as of each date that any part thereof, or any final
rule or regulation thereunder, becomes effective in accordance with its or their
terms, as the case may be (each such date, a "HIPAA Compliance Date") and (y) is
not and could not reasonably be expected to become, as of any date following any
such HIPAA Compliance Date, the subject of any civil or criminal penalty,
process, claim, action or proceeding, or any administrative or other regulatory
review, survey, process or proceeding (other than routine surveys or reviews
conducted by any government health plan or other accreditation entity) that
could result in any of the foregoing or that could reasonably be expected to
adversely affect Borrower's business, operations, assets, properties or
condition (financial or otherwise), in connection with any actual or potential
violation by Borrower of the then effective provisions of HIPAA.

below), Lender shall not be obligated to continue to make any Loans, Revolving
Credit Loans, advances or other extensions of credit under the Loan available to

Medicare and/or Medicaid provider numbers and provider account agreements, and
provided Lender with copies of same.

        SECTION 5.3. CLOSING. Subject to the conditions of this Article V, the
Loan shall be made available on the date as is mutually agreed by the parties

any part thereof, before the same shall be in default and before the date on
which penalties attach thereto, as well as all lawful claims for labor,
material, supplies or otherwise which, if unpaid, might become a Lien or charge
upon the properties or any part thereof of Borrower; provided, however, that
Borrower shall not be required to pay and discharge or cause to be paid and
discharged any such tax, assessment, charge, levy or claim so long as the
validity or amount thereof shall be contested in good faith and by appropriate

together with the audited annual financial statements delivered pursuant to
clause (f) of that Section, Borrower shall deliver to Lender a certificate of
its chief financial officer, in form and substance satisfactory to Lender:

                (a) setting forth the information (including detailed
calculations) required to establish whether Borrower is in compliance with the
requirements of Articles VI and VII as of the end of the period covered by the
financial statements then being furnished; and

                (b) stating that such officer has reviewed the relevant terms of
this Agreement, and has made (or caused to be made under such officer's
supervision) a review of the transactions and conditions of Borrower from the
beginning of the accounting period covered by the income statements being
delivered to the date of the certificate, and that such review has not disclosed
the existence during such period of any fact, event or circumstance that
constitutes an Event of Default or that is then, or with the passage of time or
giving of notice or both, could become an Event of Default, and if any such
condition or event existed during such period or now exists, specifying the
nature and period of existence thereof and what action Borrower has taken or
proposes to take with respect thereto.

        SECTION 6.22. NET WORTH. Borrower will not at any time allow its
tangible net worth, as computed in accordance with GAAP, to fall below the

        SECTION 6.23. INTENTIONALLY LEFT BLANK.

                                       26
<PAGE>   28

        SECTION 6.24. POST-CLOSING OBLIGATIONS. Borrower shall cause to be
performed and completed, to Lender's satisfaction, all of the obligations set
forth on Schedule 6.24 hereto within the time periods set forth on Schedule
6.24.

        SECTION 6.25. INTENTIONALLY LEFT BLANK.

        SECTION 6.26. CAPITAL ADEQUACY AND OTHER ADJUSTMENTS. In the event that
Lender shall have determined that the adoption after the date hereof of any law,
treaty, governmental (or quasi-governmental) rule, regulation, guideline or
order regarding capital adequacy, reserve requirements or similar requirements
or compliance by Lender or any corporation controlling Lender with any request
or directive regarding capital adequacy, reserve requirements or similar
requirements (whether or not having the force of law and whether or not failure
to comply therewith would be unlawful) from any central bank or governmental
agency or body having jurisdiction does or shall have the effect of increasing
the amount of capital, reserves or other funds required to be maintained by
Lender or any corporation controlling Lender and thereby reducing the rate of
return on Lender's or such corporation's capital as a consequence of its
obligations hereunder, then Borrower shall from time to time within fifteen (15)
days after notice and demand from Lender pay to Lender additional amounts
sufficient to compensate Lender for such reduction. A certificate as to the
amount of such cost and showing the basis of the computation of such cost
submitted by such Lender to Borrower shall, absent manifest error, be final,
conclusive and binding for all purposes.

        SECTION 6.27. TAXES.

                (a) No Deductions. Any and all payments or reimbursements made
under the Loan Documents shall be made free and clear of and without deduction
for any and all taxes, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto of any nature whatsoever imposed by any
taxing authority, excluding such taxes to the extent imposed on Lender's net
income by the jurisdiction in which Lender is organized. If Borrower shall be
required by law to deduct any such amounts from or in respect of any sum payable
hereunder to Lender, then the sum payable hereunder shall be increased as may be
necessary so that, after making all required deductions, Lender receives an
amount equal to the sum it would have received had no such deductions been made.

                (b) Changes in Tax Laws. In the event that, subsequent to the
initial advance under the Loan, (1) any changes in any existing law, regulation,
treaty or directive or in the interpretation or application thereof, (2) any new
law, regulation, treaty or directive enacted or any interpretation or
application thereof, or (3) compliance by Lender with any request or directive
(whether or not having the force of law) from any governmental authority, agency
or instrumentality:

                        (A) does or shall subject Lender to any tax of any kind
whatsoever with respect to this Agreement or the other Loan Documents, or change
the basis of taxation of payments to Lender of principal, fees, interest or any
other amount payable hereunder (except for net income taxes, or franchise taxes
imposed in lieu of net income taxes, imposed generally by federal, state or
local taxing authorities with respect to interest or commitment fees or other
fees payable hereunder or changes in the rate of tax on the overall net income
of Lender); or

                        (B) does or shall impose on Lender any other condition
or increased cost in connection with the transactions contemplated hereby or
participations herein;

and the result of any of the foregoing is to increase the cost to Lender of
making or continuing the Loan hereunder, as the case may be, or to reduce any
amount receivable hereunder, then, in any such case, Borrower shall promptly pay
to Lender, upon its demand, any additional amounts necessary to compensate
Lender, on an after-tax basis, for such additional cost or reduced amount
receivable, as determined by Lender with respect to this Agreement or the

                                       27
<PAGE>   29

other Loan Documents. If Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify Borrower of the event by
reason of which Lender has become so entitled. A certificate as to any
additional amounts payable pursuant to the foregoing sentence submitted by
Lender to Borrower shall, absent manifest error, be final, conclusive and
binding for all purposes.

        SECTION 6.28. FURTHER DOCUMENTATION. In the event any further
documentation or information is (a) required by Lender or any prospective
transferee in connection with selling, transferring, delivering, assigning,
securitizing or granting a participation in the Loan (or transferring the
servicing of the Loan), or (b) deemed necessary or appropriate by Lender in the
exercise of its rights under the Loan Documents or to correct patent mistakes in
the Loan Documents, materials relating to mortgagee's land title insurance or
the funding of the Loan, Borrower shall provide, or cause to be provided to
Lender, at Borrower's cost and expense, such documentation or information.
Borrower shall execute and deliver to Lender and/or the prospective transferee
or servicer such documentation, including but not limited to, any amendments,
corrections, deletions or additions to the Loan Documents as is required by
Lender and/or the prospective transferee; provided, however, that Borrower shall
not be required to do anything that has the effect of changing the essential
economic terms of the Loan set forth in the Loan Documents.

        SECTION 6.29. COMPLIANCE WITH REQUIREMENTS OF PROSPECTIVE TRANSFEREE.
Borrower shall do anything necessary to comply with the requirements of any
prospective transferee or servicer of the Loan, in order to enable Lender or
such transferee to sell, transfer, deliver, assign, securitize or grant a
participation in the Loan; provided, however, that Borrower shall not be
required to do anything that has the effect of changing the essential economic
terms of this Agreement.

        SECTION 6.30. TERMINATION/DEFAULT OF CONTRACTS. Borrower shall notify
Lender of any (a) default or event of default under, (b) termination of, or (c)
failure of any party to renew, any of Borrower's contracts (unless the default
or event of default under, termination of or failure to renew such contract, as
the case may be, could not reasonably be expected to have a material adverse
effect on Borrower, including without limitation, on Borrower's business, the
Collateral or the Loan hereunder) as soon as reasonably possible (other than
with respect to any notice of default, termination or failure to renew that
originates with Borrower, which notice shall be sent concurrently to Lender).
Notwithstanding anything in this Section 6.30 to the contrary, no provision in
this Section 6.30 shall modify, reduce or otherwise affect Lender's rights
hereunder or under any other Loan Document.

                                   ARTICLE VII

                               NEGATIVE COVENANTS

        Borrower covenants and agrees that so long as Borrower may borrow under
this Agreement and until payment in full of the Note and performance of all
other obligations of Borrower under the Loan Documents:

        SECTION 7.1. BORROWING. Borrower will not create, incur, assume or
suffer to exist any liability for Borrowed Money except: (a) indebtedness to
Lender; (b) accounts payable to trade creditors and current operating expenses
(other than for borrowed money) which are not aged more than one hundred twenty
(120) days from the billing date or more than thirty (30) days from the due
date, in each case incurred in the ordinary course of business and paid within
such time period, unless the same are being contested in good faith and by
appropriate and lawful proceedings, and Borrower shall have set aside such
reserves, if any, with respect thereto as are required by GAAP and deemed
adequate by Borrower and its independent accountants; (c) borrowings incurred in
the ordinary course of its business and not exceeding $25,000.00 in the
aggregate outstanding at any one time; and (d) indebtedness secured by Permitted
Liens. Borrower will not make prepayments on any existing or future indebtedness
for

                                       28
<PAGE>   30

Borrowed Money to any Person (other than Lender, to the extent permitted by this
Agreement or any subsequent agreement between Borrower and Lender).

        SECTION 7.2. JOINT VENTURES. Borrower will not invest directly or
indirectly in any joint venture for any purpose without the prior written notice
to, and the prior written consent of, Lender, which consent shall not be
unreasonably withheld.

        SECTION 7.3. NO LIENS AND ENCUMBRANCES; NO DISPOSITION OF THE
COLLATERAL. Lender does not authorize, and Borrower agrees not to: (a) create,
incur, assume or suffer to exist any mortgage, pledge, Lien or other encumbrance
of any kind (including the charge upon property purchased under a conditional
sale or other title retention agreement) upon, or any security interest in, any
of its Collateral, whether now owned or hereafter acquired, except for Permitted
Liens; (b) make any sale or leases of any of the Collateral other than any sale
of inventory in the ordinary course of business and, to the extent no Event of
Default has occurred or is continuing hereunder in which case Lender's prior
written approval shall be required, any sale in the ordinary course of business
of equipment, parts or machinery that is obsolete or no longer used or useful in
the conduct of the business of Borrower as determined by Borrower in its
reasonable discretion; or (c) license any of the Collateral.

        SECTION 7.4. RESTRICTION ON FUNDAMENTAL CHANGES. Borrower will not: (a)
enter into any transaction of merger or consolidation; (b) liquidate, wind-up or

lease, sublease, transfer or otherwise dispose of, in one transaction or a
series of transactions, any of its assets, or the capital stock of any
subsidiary of Borrower, whether now owned or hereafter acquired; or (d) acquire
by purchase or otherwise all or any substantial part of the business or assets
of, or stock or other evidence of beneficial ownership of, any Person. Borrower
agrees that compliance with this Section 7.4 is a material inducement to
Lender's advancing credit under this Agreement and Borrower further agrees that
any breach of the terms of this Section 7.4 shall constitute fraud. Borrower
further agrees that in addition to all other remedies available to Lender,
Lender shall be entitled to specific enforcement of the covenants in this
Section 7.4, including injunctive relief.

        SECTION 7.5. SALE AND LEASEBACK. Borrower will not, directly or
indirectly, enter into any arrangement whereby Borrower sells or transfers all
or any part of its assets and thereupon and within one year thereafter rents or

prior written consent of Lender, which consent shall not be unreasonably
withheld.

        SECTION 7.6. DISTRIBUTIONS AND MANAGEMENT FEES. Borrower shall not make
any "Distributions" (as defined below) to any of its Affiliates or to any
shareholder, member, partner or other person holding an equity interest in
Borrower or to any other Person related to or affiliated with any of the
foregoing (each, a "Related Party"). "Distributions" shall mean management fees,
salaries or other fees or compensation, lease or rental payments, repayments of
or debt service on loans or other indebtedness, dividends or other distributions
with respect to any of its stock, partnership or membership interests (as the
case may be) now or hereafter outstanding, the purchase, redemption or other
acquisition for value of any of its stock, partnership or membership interests
(as the case may be) now or hereafter outstanding, or the return of any capital
of its stockholders, partners or members. Notwithstanding the foregoing, so long
as no Event of Default has occurred and is continuing, Borrower may pay salaries
to the Related Party(ies) identified in Schedule 7.6 in the amount(s) described
in Schedule 7.6.

        SECTION 7.7. LOANS. Borrower will not make loans or advances to any
Person, other than (a) trade credit extended in the ordinary course of its
business, and (b) advances for business travel and similar temporary advances
made in the ordinary course of business to officers, stockholders, directors,
and employees.

        SECTION 7.8. CONTINGENT LIABILITIES. Borrower will not assume,

        SECTION 7.11. CERTIFICATES OF NEED. Borrower will not amend, alter or

any transaction, including without limitation the purchase, sale, or exchange of
property, or the loaning or giving of funds to any Affiliate or subsidiary,
except in the ordinary course of business and pursuant to the reasonable
requirements of Borrower's business and upon terms substantially the same and no
less favorable to Borrower as it would obtain in a comparable arm's length
transaction with any Person not an Affiliate or subsidiary, and so long as the
transaction is not otherwise prohibited under this Agreement. For purposes of
the foregoing, Lender consents to the transactions described on Schedule 7.12.

        SECTION 7.13. USE OF LENDER'S NAME. Borrower will not use Lender's name
(or the name of any of Lender's affiliates) in connection with any of its
business operations. Borrower may disclose to third parties that Borrower has a

intended to permit or authorize Borrower to make any contract on behalf of
Lender.

        SECTION 7.14. CHANGE IN CAPITAL STRUCTURE. Without Lender's prior
written consent, (a) there shall occur no change in the legal or beneficial
ownership of the capital stock, or in the capital structure, of Borrower or any

        SECTION 7.17. TRUTH OF STATEMENTS AND CERTIFICATES. Borrower will not
furnish to Lender any certificate or other document that contains any untrue
statement of a material fact or that omits to state a material fact necessary to
make it not misleading in light of the circumstances under which it was
furnished.

        SECTION 7.18. CONFIDENTIALITY. Borrower will not disclose the contents
of this Loan Agreement and the other Loan Documents to any third party
(including, without limitation, any financial institution or intermediary)
without Lender's prior written consent, other than to Borrower's officers and
advisors on a need-to-know basis. Borrower agrees to inform all such persons who
receive information concerning this Agreement that such information is
confidential and may not be disclosed to any other person. Lender reserves the
right to review and approve all materials that Borrower prepares that contain
Lender's name or describe this Agreement.

(as defined in the Asset Purchase Agreement) to Ivonyx and agrees that, as
between Borrower and Parent, Parent shall make any and all Earnout Payments
(including the cash portion of such payments) required to be made under the
Asset Purchase Agreement in full unless and until (a) the cash portion of the
Earnout Payment exceeds Parent's aggregate cash and cash equivalents at the time
such Earnout Payment is required to be made, (b) Lender shall have been provided
with notice of and consented in writing to Borrower's proposal to pay to Ivonyx
directly the cash portion of the Earnout Payment that Parent is unable to pay as
provided in subsection (a) above and (c) no Event of Default or event which,
with the giving of notice or passage of time or both could constitute an Event
of Default, is occurring or continuing at the time such payment is required to
be made.

                                  ARTICLE VIII

                                EVENTS OF DEFAULT

this Agreement) for the payment of Borrowed Money having an aggregate principal
amount in excess of $50,000 is not paid when due or within any applicable grace
period, or such obligation becomes or is declared to be due and payable before

payable;

                (f) Borrower makes an assignment for the benefit of creditors,

behalf of Borrower of any pending litigation, arbitration or other claim or
otherwise disputed matter, in any event not fully and unconditionally covered by
insurance, shall remain unpaid, unstayed on appeal, undischarged, unbonded and
undismissed for a period of ten (10) days;

                (i) a Reportable Event that might constitute grounds for
termination of any Plan covered by Title IV of ERISA or for the appointment by
the appropriate United States District Court of a trustee to administer any such
Plan or for the entry of a Lien or encumbrance to secure any deficiency, has
occurred and is continuing thirty (30) days after its occurrence, or any such

                (j) any outstanding equity interest in Borrower is sold or

                (l) INTENTIONALLY LEFT BLANK;

                (m) upon the issuance of any execution or distraint process

individually or in the aggregate;

                (n) Borrower ceases any material portion of its business

unremedied for a period of ten (10) days after written notice from Lender;

                (p) Borrower or any Affiliate of Borrower, shall challenge or

                                       32
<PAGE>   34

                (r) there shall occur a material adverse change in the financial
condition or business prospects of Borrower, or if Lender in good faith deems

        Notwithstanding the foregoing, Borrower's failure to comply with any
same provision of this Agreement two (2) times in any twelve (12) month period
shall effect an immediate Event of Default (without the expiration of any
applicable cure period) with respect to all subsequent failures by Borrower to
comply with such provision of this Agreement, and Lender thereupon may exercise
any remedy set forth in this Article VIII without affording Borrower any
opportunity to cure such Event of Default.

        SECTION 8.2. ACCELERATION. Upon the occurrence of any of the foregoing
Events of Default, the Obligations under the Note shall become and be
immediately due and payable upon declaration to that effect delivered by Lender
to Borrower; provided that, upon the happening of any event specified in Section
8.1(g), all Obligations including, without limitation the Termination Fee, shall
be immediately due and payable without declaration or other notice to Borrower.

        SECTION 8.3. REMEDIES.

                (a) Upon the occurrence of and during the continuance of an
Event of Default under this Agreement or the other Loan Documents, Lender, in
addition to all other rights, options, and remedies granted to Lender under this
Agreement or at law or in equity, may take any of the following steps (which
list is given by way of example and is not intended to be an exhaustive list of
all such rights and remedies):

                        (i) terminate the Loan, whereupon all outstanding
Obligations (including without limitation the Termination Fee) shall be
immediately due and payable;

                        (ii) exercise all other rights granted to it under this
Agreement and all rights under the UCC in effect in the applicable
jurisdiction(s) and under any other applicable law; and

                        (iii) exercise all rights and remedies under all Loan
Documents now or hereafter in effect, including but not limited to:

                                (A) the right to take possession of, send
notices regarding, and collect directly the Collateral, with or without judicial
process;

                                (B) the right to (by its own means or with
judicial assistance) enter any of Borrower's premises and take possession of the
Collateral, or render it unusable, or dispose of the Collateral on such premises
in compliance with subsection (C) below, without any liability for rent,
storage, utilities, or other sums, and Borrower shall not resist or interfere
with such action;

                                (C) the right to require Borrower at Borrower's
expense to assemble all or any part of the Collateral and make it available to
Lender at any place designated by Lender;

                                (D) the right to reduce the Maximum Loan Amount
or to use the Collateral and/or funds in the Concentration Account in amounts up
to the Maximum Loan Amount for any reason; and

                                       33
<PAGE>   35

                                (E) the right to enforce Borrower's rights
against Account Debtors and other obligors, including, but not limited to, the
right to collect Accounts directly in Lender's own name and to charge the
collection costs and expenses, including attorneys' fees, to Borrower.

                (b) Borrower agrees that a notice received by it at least five
(5) days before the time of any intended public sale, or the time after which
any private sale or other disposition of the Collateral is to be made, shall be
deemed to be reasonable notice of such sale or other disposition. If permitted
by applicable law, any perishable Collateral which threatens to speedily decline
in value or which is sold on a recognized market may be sold immediately by
Lender without prior notice to Borrower. At any sale or disposition of
Collateral, Lender may (to the extent permitted by applicable law) purchase all
or any part of the Collateral, free from any right of redemption by Borrower,
which right is hereby waived and released. Borrower covenants and agrees not to
interfere with or impose any obstacle to Lender's exercise of its rights and
remedies with respect to the Collateral. Lender shall have no obligation to
clean-up or otherwise prepare the Collateral for sale. Lender may comply with
any applicable state or federal law requirements in connection with a
disposition of the Collateral and compliance will not be considered to adversely
affect the commercial reasonableness of any sale of the Collateral. Lender may
sell the Collateral without giving any warranties as to the Collateral. Lender
may specifically disclaim any warranties of title or the like. This procedure
will not be considered to adversely affect the commercial reasonableness of any
sale of the Collateral. If Lender sells any of the Collateral upon credit,
Borrower will be credited only with payments actually made by the purchaser,
received by Lender and applied to the indebtedness of the purchaser. In the
event the purchaser fails to pay for the Collateral, Lender may resell the
Collateral and Borrower shall be credited with the proceeds of the sale.

                (c) Lender shall have no obligation to marshal any assets in
favor of Borrower, or against or in payment of the Note, any of the other
Obligations or any other obligation owed to Lender by Borrower or any other
person.

        SECTION 8.4. NATURE OF REMEDIES. Lender shall have the right to proceed
against all or any portion of the Collateral to satisfy in any order (a) the
liabilities and Obligations of Borrower or any of its subsidiaries or Affiliates
to Lender or any Affiliate of Lender under this Agreement or any other loan
documents evidencing financings provided to Borrower or (b) the liabilities and
obligations of Borrower, Guarantor and their respective Affiliates to Lender
under the Affiliated Loan Documents. All rights and remedies granted Lender
under this Agreement and under any agreement referred to in this Agreement, or
otherwise available at law or in equity, shall be deemed concurrent and
cumulative, and not alternative remedies, and Lender may proceed with any number
of remedies at the same time until the Loan, and all other existing and future
liabilities and obligations of Borrower to Lender, are satisfied in full. The
exercise of any one right or remedy shall not be deemed a waiver or release of
any other right or remedy, and Lender, upon the occurrence of an Event of
Default, may proceed against Borrower, and/or the Collateral, at any time, under
any agreement, with any available remedy and in any order. All sums received
from Borrower and/or the Collateral in respect of the Loan may be applied by
Lender to the any other liabilities and obligations of Borrower under the Loan
Documents and the Affiliated Loan Documents in such order of application and in
such amounts as Lender shall deem appropriate in its sole and absolute
discretion. Borrower waives any right it may have to require Lender to pursue
any Person for any of the Obligations.

                                   ARTICLE IX

                                  MISCELLANEOUS

        SECTION 9.1. EXPENSES AND TAXES.

                (a) Borrower agrees to pay, whether or not the Closing occurs, a
reasonable documentation preparation fee, together with reasonable legal, audit
and appraisal fees and all other reasonable charges and

                                       34
<PAGE>   36

expenses (including actual out-of-pocket expenses) incurred by Lender in
connection with the negotiation, preparation, legal review and execution of each
of the Loan Documents, including but not limited to UCC and judgment lien
searches and UCC filings and fees for post-Closing UCC and judgment lien
searches. In addition, Borrower shall pay all such fees associated with any
amendments, modifications and terminations to the Loan Documents following
Closing, except those amendments necessitated by the syndication, participation
or other transfer of the Loan by Lender. If Lender uses in-house counsel for any
of these purposes, Borrower further agrees that its Obligations under the Loan
Documents include reasonable charges for such work commensurate with the fees
that would otherwise be charged by outside legal counsel selected by Lender for
the work performed.

                (b) Borrower also agrees to pay all out-of-pocket charges and
expenses incurred by Lender (including the fees and expenses of Lender's
counsel) in connection with the enforcement, protection or preservation of any
right or claim of Lender, the termination of this Agreement, the termination of
any Liens of Lender on the Collateral, or the collection of any amounts due
under the Loan Documents. If Lender uses in-house counsel for any of these
purposes (i.e., for any task in connection with the enforcement, protection or
preservation of any right or claim of Lender and the collection of any amounts
due under its Loan Documents), Borrower further agrees that its Obligations
under the Loan Documents include reasonable charges for such work commensurate
with the fees that would otherwise be charged by outside legal counsel selected
by Lender for the work performed.

                (c) Borrower shall pay all taxes (other than taxes based upon or
measured by Lender's income or revenues or any personal property tax), if any,
in connection with the issuance of the Note and the recording of the security
documents therefor. The obligations of Borrower under this clause (c) shall
survive the payment of Borrower's indebtedness under this Agreement and the
termination of this Agreement.

        SECTION 9.2. ENTIRE AGREEMENT; AMENDMENTS. This Agreement and the other
Loan Documents constitute the full and entire understanding and agreement among
the parties with regard to their subject matter and supersede all prior written
or oral agreements, understandings, representations and warranties made with
respect thereto. No amendment, supplement or modification of this Agreement nor
any waiver of any provision thereof shall be made except in writing executed by
the party against whom enforcement is sought.

        SECTION 9.3. NO WAIVER; CUMULATIVE RIGHTS. No waiver by any party to
this Agreement of any one or more defaults by the other party in the performance
of any of the provisions of this Agreement shall operate or be construed as a
waiver of any future default or defaults, whether of a like or different nature.
No failure or delay on the part of any party in exercising any right, power or
remedy under this Agreement, nor acceptance of partial performance or partial
payment, shall operate as a waiver of such right, power or remedy nor shall any
single or partial exercise of any such right, power or remedy preclude any other
or further exercise of such right, power or remedy or the exercise of any other
right, power or remedy. The remedies provided for in this Agreement are
cumulative and are not exclusive of any remedies that may be available to any
party to this Agreement at law, in equity or otherwise.

        SECTION 9.4. NOTICES. Any notice or other communication required or
permitted under this Agreement shall be in writing and personally delivered,
mailed by registered or certified mail (return receipt requested and postage
prepaid), sent by telecopier (with a confirming copy sent by regular mail), or

any extent, invalid or unenforceable, the remainder of this Agreement and the
application of such term, covenant, or condition to parties or circumstances
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term, covenant or condition shall be valid and
enforced to the fullest extent permitted by law. Upon determination that any
such term is invalid, illegal or unenforceable, Lender may, but is not obligated
to, advance funds to Borrower under this Agreement until the parties to this
Agreement amend this Agreement so as to effect the original intent of the
parties as closely as possible in a valid and enforceable manner.

        SECTION 9.6. SUCCESSORS AND ASSIGNS. This Agreement, the Note, and the
other Loan Documents shall be binding upon and inure to the benefit of Borrower
and Lender and their respective successors and assigns and shall bind all
Persons who become bound as a debtor to this Agreement. Notwithstanding the
foregoing, Borrower may not assign any of its rights or delegate any of its
obligations under this Agreement without the prior written consent of Lender,
which may be withheld in its sole discretion. Lender may sell, assign, transfer,
or participate any or all of its rights or obligations under this Agreement
without notice to or consent of Borrower.

        SECTION 9.7. COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which shall be deemed an original, but all of which
together shall constitute but one instrument.

<PAGE>   38

        SECTION 9.8. INTERPRETATION. No provision of this Agreement or any other
Loan Document shall be interpreted or construed against any party because that
party or its legal representative drafted that provision. The titles of the
paragraphs of this Agreement are for convenience of reference only and are not
to be considered in construing this Agreement. Any pronoun used in this
Agreement shall be deemed to include singular and plural and masculine, feminine
and neuter gender as the case may be. The words "herein," "hereof," and
"hereunder" shall be deemed to refer to this entire Agreement, except as the
context otherwise requires.

representations and warranties made in this Agreement, any other Loan Document,

satisfied in full.

        SECTION 9.10. RELEASE OF LENDER. For and in consideration of the Loan
and each advance or other financial accommodation hereunder, each Borrower,
voluntarily, knowingly, unconditionally, and irrevocably, with specific and
express intent, for and on behalf of itself and its agents, attorneys, heirs,
successors, and assigns (collectively the "Releasing Parties") does hereby fully
and completely release, acquit and forever discharge Lender, and its successors,
assigns, heirs, affiliates, subsidiaries, parent companies, principals,
directors, officers, employees, shareholders and agents (hereinafter called the
"Lender Parties"), and any other person, firm, business, corporation, insurer,
or association which may be responsible or liable for the acts or omissions of
the Lender Parties, or who may be liable for the injury or damage resulting
therefrom (collectively the "Released Parties"), of and from any and all
actions, causes of action, suits, debts, disputes, damages, claims, obligations,
liabilities, costs, expenses and demands of any kind whatsoever, at law or in
equity, whether matured or unmatured, liquidated or unliquidated, vested or
contingent, choate or inchoate, known or unknown that the Releasing Parties (or
any of them) have or may have, against the Released Parties or any of them
(whether directly or indirectly), other than any such acts or omissions arising
from the gross negligence or willful misconduct of any Lender Party. Borrower
acknowledges that the foregoing release is a material inducement to Lender's
decision to extend to Borrower the financial accommodations hereunder and has
been relied upon by Lender in agreeing to make the Loan and in making each
advance of Loan proceeds hereunder.

        SECTION 9.11. TIME. Whenever Borrower is required to make any payment or
perform any act on a Saturday, Sunday, or a legal holiday under the laws of the
State of Maryland (or other jurisdiction where Borrower is required to make the
payment or perform the act), the payment may be made or the act performed on the
next Business Day. Time is of the essence in Borrower's performance under this
Agreement and all other Loan Documents.

        SECTION 9.12. COMMISSIONS. The transaction contemplated by this
Agreement was brought about by Lender and Borrower acting as principals and
without any brokers, agents, or finders being the effective procuring cause
other than Commonwealth Associates. Borrower represents that all fees and other
amounts payable to Commonwealth Associates in connection with the transaction
contemplated by this Agreement shall be borne by Parent, and that neither Lender
nor Borrower shall have any liability therefor. Borrower represents that it has
not committed Lender to the payment of any brokerage fee, commission, or charge
in connection with this transaction. If any such claim is made on Lender by any
broker, finder, or agent or other person, Borrower will indemnify, defend, and
hold Lender harmless from and against the claim and will defend any action to
recover on that claim, at Borrower's cost and expense, including Lender's
counsel fees. Borrower further agrees that until any such claim or demand is
adjudicated in Lender's favor, the amount demanded will be deemed a liability of
Borrower under this Agreement, secured by the Collateral.

        SECTION 9.13. THIRD PARTIES. No rights are intended to be created under
this Agreement or under any other Loan Document for the benefit of any third
party donee, creditor, or incidental beneficiary of Borrower.

                                       37
<PAGE>   39

Nothing contained in this Agreement shall be construed as a delegation to Lender
of Borrower's duty of performance, including without limitation Borrower's
duties under any account or contract in which Lender has a security interest.

        SECTION 9.14. DISCHARGE OF BORROWER'S OBLIGATIONS. Lender, in its sole
discretion, shall have the right at any time, and from time to time, without
prior notice to Borrower if Borrower fails to do so, to: (a) obtain insurance
covering any of the Collateral as required under this Agreement; (b) pay for the
performance of any of Borrower's obligations under this Agreement; (c) discharge
taxes, Liens, security interests, or other encumbrances at any time levied or
placed on any of the Collateral in violation of this Agreement unless Borrower
is in good faith with due diligence by appropriate proceedings contesting those
items; and (d) pay for the maintenance and preservation of any of the
Collateral. Expenses and advances shall be added to the Loan, until reimbursed
to Lender and shall be secured by the Collateral. Any such payments and advances
by Lender shall not be construed as a waiver by Lender of an Event of Default.

        SECTION 9.15. INFORMATION TO PARTICIPANTS. Lender may divulge to any
participant it may obtain in the Loan, or any portion of the Loan, all
information, and furnish to such participant copies of reports, financial
statements, certificates, and documents obtained under any provision of this
Agreement or any other Loan Document; provided that Lender shall require that
any such participant execute a confidentiality agreement with respect to such
information.

        SECTION 9.16. INDEMNITY. Borrower hereby indemnifies and agrees to
defend (with counsel acceptable to Lender) and hold harmless Lender, its
partners, officers, agents and employees (collectively, "Indemnitee") from and
against any liability, loss, cost, expense (including reasonable attorneys' fees
and expenses for both in-house and outside counsel), claim, damage, suit, action
or proceeding ever suffered or incurred by Lender or in which Lender may ever be
or become involved (whether as a party, witness or otherwise) (a) arising from
Borrower's failure to observe, perform or discharge any of its covenants,
obligations, agreements or duties under this Agreement, (b) arising from the
breach of any of the representations or warranties contained in Article IV of
this Agreement, (c) by reason of this Agreement, the other Loan Documents or the
transactions contemplated hereby or thereby, or (d) relating to claims of any
Person with respect to the Collateral other than, in each case, to the extent
arising from the gross negligence or willful misconduct of Indemnitee.
Notwithstanding any contrary provision in this Agreement, the obligation of
Borrower under this Section 9.16 shall survive the payment in full of the
Obligations and the termination of this Agreement.

        SECTION 9.17. INTENTIONALLY LEFT BLANK.

        SECTION 9.18. LENDER APPROVALS. Unless expressly provided herein to the
contrary, any approval, consent, waiver or satisfaction of Lender with respect
to any matter that is the subject of this Agreement or the other Loan Documents
may be granted or withheld by Lender in its sole and absolute discretion.

        SECTION 9.18A. FURTHER ASSURANCES. Borrower hereby agrees that at any
time and from time to time, at the expense of Borrower, Borrower will promptly
execute and deliver all further instruments and documents, and take all further
action, that may be necessary or that Lender may reasonably request, in order to
perfect and protect any security interest granted or purported to be granted
hereby, or to enable Lender or any of its agents to exercise and enforce its
rights and remedies under this Agreement with respect to any portion of such
collateral.

        SECTION 9.19. CHOICE OF LAW; CONSENT TO JURISDICTION. EXCEPT TO THE
EXTENT THAT THE UCC PROVIDES FOR THE APPLICATION OF THE LAW OF THE BORROWER'S
STATE OF ORGANIZATION, THIS AGREEMENT AND THE NOTE SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF MARYLAND, WITHOUT REGARD
TO ANY OTHERWISE APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS. IF ANY ACTION
ARISING OUT OF THIS AGREEMENT OR THE NOTE IS COMMENCED BY LENDER IN

                                       38
<PAGE>   40

THE STATE COURTS OF THE STATE OF MARYLAND OR IN THE U.S. DISTRICT COURT FOR THE
DISTRICT OF MARYLAND, BORROWER HEREBY CONSENTS TO THE JURISDICTION OF ANY SUCH
COURT IN ANY SUCH ACTION AND TO THE LAYING OF VENUE IN THE STATE OF MARYLAND.
ANY PROCESS IN ANY SUCH ACTION SHALL BE DULY SERVED IF MAILED BY REGISTERED
MAIL, POSTAGE PREPAID, TO BORROWER AT ITS ADDRESS DESCRIBED IN SECTION 9.4. OR
IF SERVED BY ANY OTHER MEANS PERMITTED BY APPLICABLE LAW.

        SECTION 9.20. COOPERATION IN DISCOVERY AND LITIGATION. IN ANY
LITIGATION, TRIAL, ARBITRATION OR OTHER DISPUTE RESOLUTION PROCEEDING RELATING
TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, ALL DIRECTORS, OFFICERS,
EMPLOYEES AND AGENTS OF BORROWER OR OF ITS AFFILIATES SHALL BE DEEMED TO BE
EMPLOYEES OR MANAGING AGENTS OF BORROWER FOR PURPOSES OF ALL APPLICABLE LAW OR
COURT RULES REGARDING THE PRODUCTION OF WITNESSES BY NOTICE FOR TESTIMONY
(WHETHER IN A DEPOSITION, AT TRIAL OR OTHERWISE). BORROWER AGREES THAT LENDER'S
COUNSEL IN ANY SUCH DISPUTE RESOLUTION PROCEEDING MAY EXAMINE ANY OF THESE
INDIVIDUALS AS IF UNDER CROSS-EXAMINATION AND THAT ANY DISCOVERY DEPOSITION OF
ANY OF THEM MAY BE USED IN THAT PROCEEDING AS IF IT WERE AN EVIDENCE DEPOSITION.
BORROWER IN ANY EVENT WILL USE ALL COMMERCIALLY REASONABLE EFFORTS TO PRODUCE IN
ANY SUCH DISPUTE RESOLUTION PROCEEDING, AT THE TIME AND IN THE MANNER REQUESTED
BY LENDER, ALL PERSONS, DOCUMENTS (WHETHER IN TANGIBLE, ELECTRONIC OR OTHER
FORM) OR OTHER THINGS UNDER BORROWER'S CONTROL AND RELATING TO THE DISPUTE IN
ANY JURISDICTION THAT RECOGNIZES THAT (OR ANY SIMILAR) DISTINCTION.

        SECTION 9.21. WAIVER OF TRIAL BY JURY. BORROWER HEREBY (A) COVENANTS AND
AGREES NOT TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY A JURY, AND
(B) WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT
SHALL NOW OR HEREAFTER EXIST. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS
SEPARATELY GIVEN, KNOWINGLY AND VOLUNTARILY, BY BORROWER, AND THIS WAIVER IS
INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE
RIGHT TO A JURY TRIAL WOULD OTHERWISE ACCRUE. LENDER IS HEREBY AUTHORIZED AND
REQUESTED TO SUBMIT THIS AGREEMENT TO ANY COURT HAVING JURISDICTION OVER THE
SUBJECT MATTER AND THE PARTIES TO THIS AGREEMENT, SO AS TO SERVE AS CONCLUSIVE
EVIDENCE OF BORROWER'S WAIVER OF THE RIGHT TO JURY TRIAL. FURTHER, BORROWER
HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF LENDER (INCLUDING LENDER'S
COUNSEL) HAS REPRESENTED, EXPRESSLY OR OTHERWISE, TO BORROWER THAT LENDER WILL
NOT SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION.

        SECTION 9.22. CONFESSION OF JUDGMENT. BORROWER AUTHORIZES ANY ATTORNEY
ADMITTED TO PRACTICE BEFORE ANY COURT OF RECORD IN THE UNITED STATES OR THE
CLERK OF SUCH COURT TO APPEAR ON BEHALF OF BORROWER IN ANY COURT IN ONE OR MORE
PROCEEDINGS, OR BEFORE ANY CLERK THEREOF OR PROTHONOTARY OR OTHER COURT
OFFICIAL, AND TO CONFESS JUDGMENT AGAINST BORROWER IN FAVOR OF LENDER IN THE
FULL AMOUNT DUE ON THIS AGREEMENT (INCLUDING PRINCIPAL, ACCRUED INTEREST AND ANY
AND ALL CHARGES, FEES AND COSTS) PLUS ATTORNEYS' FEES EQUAL TO FIFTEEN PERCENT
(15%) OF THE AMOUNT DUE, PLUS COURT COSTS, ALL WITHOUT PRIOR NOTICE OR
OPPORTUNITY OF BORROWER FOR PRIOR HEARING; PROVIDED THAT BORROWER ACKNOWLEDGES
THAT ATTORNEYS' FEES ARE STATED TO BE FIFTEEN PERCENT (15%) SOLELY FOR PURPOSES
OF FIXING A SUM CERTAIN FOR WHICH JUDGMENT CAN BE ENTERED BY CONFESSION AND
AGREES THAT IN ENFORCING ANY SUCH JUDGMENT, LENDER SHALL NOT DEMAND, SOLELY WITH
RESPECT TO ATTORNEYS' FEES INCURRED BY LENDER IN CONNECTION WITH SUCH
INDEBTEDNESS AFTER SUCH JUDGMENT IS RENDERED, ANY AMOUNTS IN EXCESS OF THE
ACTUAL AMOUNT OF REASONABLE ATTORNEYS' FEES CHARGED BY OR BILLED TO LENDER FOR
ITS IN-HOUSE OR OUTSIDE COUNSEL (WHICH ATTORNEYS' FEES SHALL IN ANY EVENT BE
CHARGED BY OR BILLED TO LENDER AT

                                       39

COMMERCIAL HOURLY RATES FOR MATTERS OF SUCH TYPE). BORROWER AGREES AND CONSENTS
THAT VENUE AND JURISDICTION SHALL BE PROPER IN THE CIRCUIT COURT OF ANY COUNTY
OF THE STATE OF MARYLAND OR OF BALTIMORE CITY, MARYLAND, OR IN THE UNITED STATES
DISTRICT COURT FOR THE DISTRICT OF MARYLAND. BORROWER WAIVES THE BENEFIT OF ANY
AND EVERY STATUTE, ORDINANCE, OR RULE OF COURT WHICH MAY BE LAWFULLY WAIVED
CONFERRING UPON BORROWER ANY RIGHT OR PRIVILEGE OF EXEMPTION, HOMESTEAD RIGHTS,
STAY OF EXECUTION, OR SUPPLEMENTARY PROCEEDINGS, OR OTHER RELIEF FROM THE
ENFORCEMENT OR IMMEDIATE ENFORCEMENT OF A JUDGMENT OR RELATED PROCEEDINGS ON A
JUDGMENT. THE AUTHORITY AND POWER TO APPEAR FOR AND ENTER JUDGMENT AGAINST
BORROWER SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF, OR BY ANY
IMPERFECT EXERCISE THEREOF, AND SHALL NOT BE EXTINGUISHED BY ANY JUDGMENT
ENTERED PURSUANT THERETO; SUCH AUTHORITY AND POWER MAY BE EXERCISED ON ONE OR
MORE OCCASIONS FROM TIME TO TIME, IN THE SAME OR DIFFERENT JURISDICTIONS, AS
OFTEN AS LENDER SHALL DEEM NECESSARY, CONVENIENT, OR PROPER.

                              REVOLVING CREDIT NOTE

$10,000,000.00                                                  AUGUST 20, 2001

        FOR VALUE RECEIVED, the undersigned, DRKOOP LIFECARE, INC., a Delaware
corporation ("Borrower"), promises to pay, in lawful money of the United States,
to the order of HELLER HEALTHCARE FINANCE, INC., a Delaware corporation
(together with its successors and assigns, "Lender"), the principal sum of Ten
Million and No/100 Dollars ($10,000,000.00), or so much of such principal sum as
shall be advanced or readvanced and shall remain unpaid under the Loan
established pursuant to that certain Loan and Security Agreement of even date
herewith by and between the undersigned and Lender (as amended, modified,
restated or replaced from time to time, the "Loan Agreement"), plus interest on
the unpaid balance thereof, computed on a 360-day basis, at the rate per annum
that is set forth in the Loan Agreement.

        1. All capitalized terms used and not otherwise specifically defined in
this Revolving Credit Note (as amended, modified, restated or replaced from time
to time, the "Note") shall have the meanings given to them in the Loan
Agreement.

        2. This Note shall evidence the undersigned's obligation to repay all
sums advanced by Lender from time to time under the Loan Agreement and as part
of the Loan. The actual amount due and owing from time to time under this Note
shall be evidenced by Lender's records of receipts and disbursements with
respect to the Loan, which shall be conclusive evidence of that amount, absent
manifest error.

        3. Interest due pursuant to this Note shall be payable monthly, in
arrears, on the first Business Day of each month after the date of this Note
(for the previous month). For purposes of this Note, a "Business Day" shall mean
any day on which banks are open for business in Maryland, excluding Saturdays
and Sundays.

        4. This Note shall become due and payable upon the earlier to occur of
(a) the expiration of the Term, or (b) the occurrence of any Event of Default
under the Loan Agreement if the Loan and the maturity of the payment of the
Obligations are accelerated, or any other event under any other Loan Documents
which would result in this Note becoming due and payable. At such time, the
entire principal balance of this Note and all other fees, costs and expenses, if
any, shall be due and payable in full. Lender shall then have the option at any
time and from time to time to exercise all of the rights and remedies set forth
in this Note and in the other Loan Documents, as well as all rights and remedies
otherwise available to Lender at law or in equity, to collect the unpaid
indebtedness under this Note and the other Loan Documents. This Note is secured
by the Collateral, as defined in and described in the Loan Agreement.

        5. Whenever any principal and/or interest and/or fee under this Note
shall not be paid when due, whether at the stated maturity or by acceleration,
interest on such unpaid amounts shall thereafter be payable at a rate per annum
equal to five (5) percentage points above the stated rate of interest on this
Note until such amounts shall be paid.

<PAGE>   45

        6. The undersigned and Lender intend to conform strictly to the
applicable usury laws in effect from time to time during the term of the Loan.
Accordingly, if any transaction contemplated by the Loan Agreement or this Note
would be usurious under such laws, then notwithstanding any other provision
hereof: (a) the aggregate of all interest that is contracted for, charged, or
received under this Note or under any other Loan Document shall not exceed the
maximum amount of interest allowed by applicable law, and any excess shall be
promptly credited to the undersigned by Lender (or, to the extent that such
consideration shall have been paid, such excess shall be promptly refunded to
the undersigned by Lender); (b) neither the undersigned nor any other Person (as
defined in the Loan Agreement) now or hereafter liable hereunder shall be
obligated to pay the amount of such interest to the extent that it is in excess
of the maximum interest permitted by applicable law; and (c) the effective rate
of interest shall be reduced to the Highest Lawful Rate (as defined in the Loan
Agreement). All sums paid, or agreed to be paid, to Lender for the use,
forbearance, and detention of the debt of Borrower to Lender shall, to the
extent permitted by applicable law, be allocated throughout the full term of
this Note until payment is made in full so that the actual rate of interest does
not exceed the Highest Lawful Rate in effect at any particular time during the
full term thereof. If at any time the rate of interest under this Note exceeds
the Highest Lawful Rate, the rate of interest to accrue pursuant to this Note
shall be limited, notwithstanding anything to the contrary in this Note, to the
Highest Lawful Rate, but any subsequent reductions in the Base Rate shall not
reduce the interest to accrue pursuant to this Note below the Highest Lawful
Rate until the total amount of interest accrued equals the amount of interest
that would have accrued if a varying rate per annum equal to the interest rate
under the Note had at all times been in effect.

        7. This Note is the "Note" referred to in the Loan Agreement, and is
issued pursuant to the Loan Agreement. Reference is made to the Loan Agreement
for a statement of the additional rights and obligations of the undersigned and
Lender. In the event of any conflict between the terms of this Note and the
terms of the Loan Agreement, the terms of the Loan Agreement shall prevail. All
of the terms, covenants, provisions, conditions, stipulations, promises and
agreements contained in the Loan Documents to be kept, observed and/or performed
by the undersigned are made a part of this Note and are incorporated into this
Note by this reference to the same extent and with the same force and effect as
if they were fully set forth in this Note; the undersigned promises and agrees
to keep, observe and perform them or cause them to be kept, observed and
performed, strictly in accordance with the terms and provisions thereof.

        8. Each party liable on this Note in any capacity, whether as maker,
endorser, surety, guarantor or otherwise, (a) waives presentment for payment,
demand, protest and notice of presentment, notice of protest, notice of
non-payment and notice of dishonor of this debt and each and every other notice
of any kind respecting this Note and all lack of diligence or delays in
collection or enforcement hereof; (b) agrees that Lender at any time or times,
without notice to the undersigned or its consent, may grant extensions of time,
without limit as to the number of the aggregate period of such extensions, for
the payment of any principal, interest or other sums due hereunder; (c) to the
extent permitted by law, waives all exemptions under the laws of the

                                       2
<PAGE>   46

State of Maryland and/or any state or territory of the United States; (d) to the
extent permitted by law, waives the benefit of any law or rule of law intended
for its advantage or protection as an obligor under this Note or providing for
its release or discharge from liability on this Note, in whole or in part, on
account of any facts or circumstances other than full and complete payment of
all amounts due under this Note; and (e) agrees to pay, in addition to all other
sums of money due, all cost of collection and reasonable attorney's fees,
whether suit be brought or not, if this Note is not paid in full when due,
whether at the stated maturity or by acceleration.

        9. No waiver by Lender of any one or more defaults by the undersigned in
the performance of any of its obligations under this Note shall operate or be
construed as a waiver of any future default or defaults, whether of a like or
different nature. No failure or delay on the part of Lender in exercising any
right, power or remedy under this Note (including, without limitation, the right
to declare this Note due and payable) shall operate as a waiver of such right,
power or remedy nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise of such right, power or
remedy or the exercise of any other right, power or remedy.

        10. If any term, provision, covenant or condition of this Note or the
application of any term, provision, covenant or condition of this Note to any
party or circumstance shall be found by a court of competent jurisdiction to be,
to any extent, invalid or unenforceable, then the remainder of this Note and the
application of such term, provision, covenant, or condition to parties or
circumstances other than those as to which it is held invalid or unenforceable,
shall not be affected thereby, and each term, provision, covenant or condition
shall be valid and enforced to the fullest extent permitted by law. Upon
determination that any such term, provision, covenant or condition is invalid,
illegal or unenforceable, Lender may, but is not obligated to, advance funds to
Borrower under this Note until Borrower and Lender amend this Note so as to
effect the original intent of the parties as closely as possible in a valid and
enforceable manner.

        11. No amendment, supplement or modification of this Note nor any waiver
of any provision of this Note shall be made except in writing executed by the
party against whom enforcement is sought.

        12. This Note shall be binding upon the undersigned and its successors
and assigns. Notwithstanding the foregoing, the undersigned may not assign any
of its rights or delegate any of its obligations under this Note without the
prior written consent of Lender, which may be withheld in its sole discretion.

        13. THIS NOTE IS TO BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF MARYLAND WITHOUT RESPECT TO ANY OTHERWISE APPLICABLE
CONFLICTS-OF-LAWS PRINCIPLES, BOTH AS TO INTERPRETATION AND PERFORMANCE, AND THE
PARTIES EXPRESSLY CONSENT AND AGREE TO THE NON-EXCLUSIVE JURISDICTION OF THE
COURTS OF THE STATE OF MARYLAND AND THE UNITED STATES DISTRICT COURT FOR THE
DISTRICT OF MARYLAND AND TO

THE LAYING OF VENUE IN THE STATE OF MARYLAND, WAIVING ALL CLAIMS OR DEFENSES
BASED ON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE, INCONVENIENT FORUM OR
THE LIKE. BORROWER HEREBY CONSENTS TO SERVICE OF PROCESS BY MAILING A COPY OF

FURTHER WAIVES ANY CLAIM FOR CONSEQUENTIAL DAMAGES IN RESPECT OF ANY ACTION
TAKEN OR OMITTED TO BE TAKEN BY LENDER IN GOOD FAITH.

        14. IN ANY LITIGATION, TRIAL, ARBITRATION OR OTHER DISPUTE RESOLUTION
PROCEEDING RELATING TO THIS NOTE OR ANY OF THE OTHER LOAN DOCUMENTS, ALL

BE DEEMED TO BE EMPLOYEES OR MANAGING AGENTS OF BORROWER FOR PURPOSES OF ALL
APPLICABLE LAW OR COURT RULES REGARDING THE PRODUCTION OF WITNESSES BY NOTICE
FOR TESTIMONY (WHETHER IN A DEPOSITION, AT TRIAL OR OTHERWISE). BORROWER AGREES
THAT LENDER'S COUNSEL IN ANY SUCH DISPUTE RESOLUTION PROCEEDING MAY EXAMINE ANY
OF THESE INDIVIDUALS AS IF UNDER CROSS-EXAMINATION AND THAT ANY DISCOVERY
DEPOSITION OF ANY OF THEM MAY BE USED IN THAT PROCEEDING AS IF IT WERE AN
EVIDENCE DEPOSITION. BORROWER IN ANY EVENT WILL USE ALL COMMERCIALLY REASONABLE
EFFORTS TO PRODUCE IN ANY SUCH DISPUTE RESOLUTION PROCEEDING, AT THE TIME AND IN
THE MANNER REQUESTED BY LENDER, ALL PERSONS, DOCUMENTS (WHETHER IN TANGIBLE,
ELECTRONIC OR OTHER FORM) OR OTHER THINGS UNDER BORROWER'S CONTROL AND RELATING
TO THE DISPUTE IN ANY JURISDICTION THAT RECOGNIZES THAT (OR ANY SIMILAR)
DISTINCTION.

        15. THE UNDERSIGNED HEREBY (A) COVENANTS AND AGREES NOT TO ELECT A TRIAL
BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY A JURY, AND (B) WAIVES ANY RIGHT TO
TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER
EXIST. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY
BY THE UNDERSIGNED, AND THIS WAIVER IS INTENDED TO ENCOMPASS INDIVIDUALLY EACH
INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A JURY TRIAL WOULD OTHERWISE
ACCRUE. LENDER IS HEREBY AUTHORIZED AND REQUESTED TO SUBMIT THIS NOTE TO ANY
COURT HAVING JURISDICTION OVER THE SUBJECT MATTER AND THE PARTIES HERETO, SO AS
TO SERVE AS CONCLUSIVE EVIDENCE OF THE UNDERSIGNED'S WAIVER OF THE RIGHT TO JURY
TRIAL. FURTHER, THE UNDERSIGNED HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT
OF LENDER (INCLUDING LENDER'S COUNSEL) HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
TO ANY BORROWER THAT LENDER WILL NOT SEEK TO ENFORCE THIS WAIVER OF RIGHT TO
JURY TRIAL PROVISION.

PROVIDED THAT THE UNDERSIGNED ACKNOWLEDGES THAT ATTORNEYS' FEES ARE STATED TO BE

JUDGMENT CAN BE ENTERED BY CONFESSION AND AGREES THAT IN ENFORCING ANY SUCH
JUDGMENT, LENDER SHALL NOT DEMAND, SOLELY WITH RESPECT TO ATTORNEYS' FEES
INCURRED BY LENDER IN CONNECTION WITH SUCH INDEBTEDNESS AFTER SUCH JUDGMENT IS
RENDERED, ANY AMOUNTS IN EXCESS OF THE ACTUAL AMOUNT OF REASONABLE ATTORNEYS'
FEES CHARGED BY OR BILLED TO LENDER FOR ITS IN-HOUSE OR OUTSIDE COUNSEL (WHICH
ATTORNEYS' FEES SHALL IN ANY EVENT BE CHARGED BY OR BILLED TO LENDER AT

                              EMPLOYMENT AGREEMENT

            THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into
as of August 20, 2001, by and between drkoop LifeCare, Inc., a Delaware
corporation (the "Company"), and G. Peter Molloy, Jr. ("Employee").

                                    RECITALS

            WHEREAS, the Company desires to obtain the services of Employee as
its President in the manner hereinafter specified, and also to make provisions
for the payment of compensation to Employee for such services; and

            WHEREAS, Employee is willing to be employed by the Company as its
President and to perform the duties incident to such employment upon the terms
and subject to the conditions hereinafter set forth;

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, the parties hereto agree as follows:

                                    AGREEMENT

            NOW, THEREFORE, in consideration of the mutual promises and
agreements contained herein, and for other good and valuable consideration, the
receipt of which is hereby acknowledged, the parties hereto agree as follows:

            1. Start Date. The "Term of Employment" (as defined herein) shall
commence as of the date hereof, which date shall be referred to herein as the
"Start Date."

            2. Position and Duties.

                (a) The Company hereby employs Employee as the President of the
Company commencing as of the Start Date for the Term of Employment. In this
capacity, Employee shall devote his best efforts to the performance of the
services customarily incident to such office and position and to such other
services of as may be requested by the Chief Executive Officer of the Company
which may include services for drkoop.com, Inc., a Delaware corporation
("Parent") or one or more other subsidiaries of Parent (provided that Employee's
duties for Parent or any such subsidiary remain consistent with Employee's
duties under this Agreement). Employee, in his capacity as an employee of the
Company, shall be responsible to and obey the reasonable and lawful directives
of the Chief Executive Officer of the Company. Employee shall report to the
Chief Executive Officer or any other person designated by the Chief Executive
Officer, and Employee shall have such authority and duties as are customary in
such position.

                (b) Employee shall devote all of his business time and attention
to such duties, except for sick leave, reasonable vacations, and excused leaves
of absence as more particularly provided herein. Notwithstanding the foregoing,
to the extent that the time so spent does not conflict with the Company's
business, Employee may devote time to personal and

                                       1
<PAGE>   2

family investments. The existence of such a conflict shall be determined in good
faith by the Board of Directors of Parent (the "Board"). Employee shall use his
best efforts during the Term of Employment to protect, encourage, and promote
the interests of the Company.

            3. Compensation.

                (a) Base Salary. The Company shall pay to Employee during the
Term of Employment a base salary at the rate of Three Hundred Thousand Dollars
($300,000) per calendar year. Such salary shall be payable at least semi-monthly
in accordance with the Company's normal payroll procedures. (Employee's annual
salary, as set forth above or as it may be increased from time to time in the
Board's sole discretion, shall be referred to hereinafter as the "Base Salary."
The Company will review Employee's salary annually.)

                (b) Performance Bonus. In addition to the compensation otherwise
payable to Employee pursuant to this Agreement, Employee shall be eligible to
receive additional annual bonuses to the extent, if any, approved by the Board
in its sole discretion.

            4. Benefits. During the Term of Employment:

                (a) Employee shall be eligible to participate in any life,
health and long-term disability insurance programs, pension and retirement
programs, stock option and other incentive compensation programs, and other
fringe benefit programs made available to executive employees of the Company
from time to time, and Employee shall be entitled to receive such other fringe
benefits as may be granted to him from time to time by the Board. Nothing
herein, however, is intended or shall be construed to require the Company to
institute or continue all, or any particular, plan or benefits.

                (b) Employee shall be allowed four (4) weeks vacation with pay,
and leaves of absence with pay in accordance with the Company's policies in
effect from time to time.

                (c) The Company shall reimburse Employee in accordance with the
policies of the Company, as adopted and amended from time to time, for
reasonable and necessary business expenses incurred in performing Employee's
duties and promoting the business of the Company, including, cellular telephone,
travel and lodging expenses; provided Employee shall, as a condition of such
reimbursement, submit verification of the nature and amount of such expenses in
accordance with the business expense reimbursement policies from time to time
adopted by the Company.

            5. Term; Termination of Employment. As used herein, the phrase "Term
of Employment" shall mean the period commencing on the Start Date and ending one
(1) year from the Start Date; provided that as of the expiration date of such
initial one (1) year Term of Employment and (ii) if applicable, any Renewal
Period (as defined below), the Term of Employment shall automatically be
extended for one (1) year periods (each a "Renewal Period") unless either the
Company or Employee provides two (2) months notice to the contrary prior to

                                       2
<PAGE>   3

the end of the Term of Employment or applicable Renewal Period. Notwithstanding
the foregoing, the Term of Employment shall expire on the first to occur of the
following:

                (a) Termination by the Company Without Cause. Notwithstanding
anything to the contrary in this Agreement, whether express or implied, the
Company may, at any time, terminate Employee's employment for any reason other
than Cause (as defined below) by giving Employee at least thirty (30) days prior
written notice of the effective date of termination. In the event Employee's
employment hereunder is terminated by the Company other than for Cause, Employee
shall be entitled to receive his Base Salary as he would have received such
amounts during the period commencing on the effective date of such termination
and ending six (6) months after such date of termination, whether during the
initial Term of Employment, a Renewal Period or otherwise (such period
hereinafter referred to as the "Salary Continuation Period"), as if Employee
were still employed hereunder during the Salary Continuation Period; provided
that the Company's election not to extend the Term of Employment for any Renewal
Period shall be treated as a termination by the Company without Cause.

                (b) Termination for Cause. The Company shall have the right to
terminate Employee's employment at any time for Cause (as defined below) by
giving Employee written notice of the effective date of termination (which
effective date may, except as otherwise provided below, be the date of such
notice). If the Company terminates Employee's employment for Cause, Employee
shall be paid his unpaid Base Salary through the date of termination, and the
Company shall have no further obligation hereunder from and after the effective
date of termination and shall have all other rights and remedies available under
this or any other agreement and at law or in equity.

                For purposes of this Agreement, "Cause" shall mean:

                    (i) theft, forgery, fraud, misappropriation, embezzlement,
            moral turpitude or other act of material misconduct against the
            Company or any of its affiliates;

                    (ii) fraudulent or willful and material misrepresentations
            or concealments on any written reports submitted to the Company or
            any of its affiliates;

                    (iii) Employee's violation of the Company's substance abuse
            policy;

                    (iv) gross negligence or material misconduct in the
            performance of the duties of Employee required hereunder or his
            habitual neglect thereof;

                    (v) a material failure by Employee to follow or comply with
            the lawful directives of the Board;

                    (vi) a material breach by Employee of the provisions of this
            Agreement or other agreements with the Company;

                                       3
<PAGE>   4

                    (vii) willful and knowing violation of any rules or
            regulations of any governmental or regulatory body, which is or is
            reasonably expected to be materially injurious to the financial
            condition of the Company;

                    (viii) Employee's conviction of, or plea of nolo contendere
            to, any felony or to any crime or offense causing substantial harm
            to the Company or any of its affiliates (whether or not for personal
            gain) or involving acts of theft, forgery, fraud, misappropriation,
            embezzlement, moral turpitude or similar conduct;

                    (ix) Employee shall become associated with any company in
            the tobacco industry;

                    (xi) a material violation of any fiduciary duty owed to the
            Company; or

                    (xii) engagement in any act (including, but not limited to,
            unlawful discriminatory conduct) that results in substantial injury
            to the reputation, business or business relationships of the Company
            or that, in each case, has subjected, or if generally known would
            subject, the Company to public ridicule or embarrassment.

            provided, however, that in the case of the foregoing clauses (iv),
(v) and (vi) Employee shall have been informed, in writing, of such material
failure referred to in the foregoing clauses (iv), (v) and (vi) and provided
with a reasonable opportunity to cure such material failure, if such failure is
subject to cure (if such failure is subject to cure, "reasonable opportunity to
cure" shall mean a period of thirty (30) days).

                (c) Resignation for Good Reason. Employee may terminate his
employment for Good Reason (as defined below) by giving the Company at least
thirty (30) days prior written notice of the effective date of termination. In
the event Employee's employment hereunder is terminated by Employee for Good
Reason, Employee shall be entitled to receive his Base Salary as he would have
received such amounts during the Salary Continuation Period, whether during the
initial Term of Employment, a Renewal Period or otherwise, as if Employee were
still employed hereunder during the Salary Continuation Period.

                For purposes of this Agreement, "Good Reason" shall mean:

                    (i) (a) the assignment of Employee without his consent to a
            position, responsibilities or duties of a materially lesser status
            or degree of responsibility than his position, responsibilities or
            duties at the Start Date which remains uncured for at least 30 days
            after receipt of notice thereof given by Employee; or

                    (ii) any material breach by the Company in performing its
            obligations hereunder which remains uncured for at least 30 days
            after receipt of notice thereof given by Employee.

                                       4
<PAGE>   5

                (d) Termination on Account of Death. In the event of Employee's
death while in the employ of the Company, his employment hereunder shall
terminate on the date of his death and Employee shall be paid his unpaid Base
Salary through the date of termination. In addition, any other benefits payable
on behalf of Employee shall be determined under the Company's insurance and
other compensation and benefit plans and programs then in effect in accordance
with the terms of such programs.

                (e) Termination on Account of Disability. To the extent not
prohibited by The Americans With Disabilities Act of 1990, if, as a result of
Employee's incapacity due to physical or mental illness (as determined in good
faith by a physician acceptable to the Company and Employee), Employee is unable
to substantially render to the Company the services required under this
Agreement for more than ninety (90) days out of any consecutive one hundred and
eighty (180) day period or if a physician acceptable to the Company advises the
Company that it is likely that Employee will be unable to return to the
performance of his duties for more than ninety (90) days out of any consecutive
one hundred and eighty (180) day period his employment may be terminated for
"Disability." During any period that Employee fails to perform his duties with
the Company as a result of incapacity due to physical or mental illness, he
shall continue to receive his Base Salary and other benefits provided hereunder,
together with all compensation payable to him under the Company's disability
plan or program or other similar plan during such period, until Employee's
employment hereunder is terminated pursuant to this subparagraph (e).
Thereafter, Employee's benefits shall be determined under the Company's
retirement, insurance, and other compensation and benefit plans and programs
then in effect, in accordance with the terms of such programs, and the Company
shall cease to be obligated to pay Employee a Base Salary (other than any
amounts owed to Employee at the time of such termination).

            6. Confidential Information, Non-Solicitation and Non-Competition.

                (a) During the Term of Employment and thereafter, Employee shall
not, except as may be required to perform his duties hereunder or as required by
applicable law, disclose to others or use, whether directly or indirectly, any
Confidential Information regarding Parent or any subsidiary thereof (including
the Company). "Confidential Information" shall mean information about Parent,
its subsidiaries and affiliates, and their respective clients and customers that
is not available to the general public and that was learned by Employee in the
course of his employment by the Company, including, but not limited to, any
proprietary knowledge, trade secrets, data, formulae, information, and client
and customer lists and all papers, resumes, records (including computer records)
and the documents containing such Confidential Information. Employee
acknowledges that such Confidential Information is specialized, unique in nature
and of great value to Parent and its subsidiaries, and that such information
gives Parent and its subsidiaries a competitive advantage. This confidentiality
covenant has no temporal, geographic or territorial restriction. Upon the
termination of his employment for any reason whatsoever, Employee shall promptly
deliver to the Company all documents, computer tapes and disks (and all copies
thereof) containing any Confidential Information, and any other tangible
property of Parent or its subsidiaries which has been produced by, received by
or otherwise submitted to Employee during or prior to the Term of Employment.

                                       5
<PAGE>   6

                (b) By and in consideration of Employee's employment hereunder
and the payments to be made and benefits to be provided by the Company hereunder
and further in consideration of Employee's exposure to the proprietary
information of Parent and its subsidiaries (including the Company), Employee
agrees that, provided that there has not been any material breach by the Company
in performing its obligations hereunder which remains uncured for at least 30
days after receipt of written notice thereof given by Employee, during the Term
of Employment and the Salary Continuation Period, if any, or for a period of 12
months following the termination of Employee's employment if Employee's
employment is terminated for Cause or without Good Reason, Employee shall not,
directly or indirectly in any manner or capacity (e.g., as an advisor,
principal, agent, partner, officer, director, shareholder, employee, member of
any association or otherwise) engage in, work for, consult, provide advice or
assistance or otherwise participate in any activity which is competitive with
the Business of Parent or any subsidiary thereof in the metropolitan areas in
which Parent or any of its subsidiaries operate (it being understood that this
Section 6(b) shall not prohibit Employee from working for, consulting, providing
advice or other assistance to or otherwise participating in a business (an
"Other Company") that engages in the Business but whose principal line of
business is not the Business so long as Employee does not work for, consult,
provide advice or other assistance to (including, without limitation, by way of
promotion or endorsement) or otherwise participate in any aspect of the Business
conducted or proposed to be conducted by the Other Company). For purposes of
this Agreement, the "Business" shall mean any specific business activity
conducted by Parent or any successor thereto or any of Parent's subsidiaries or
proposed to be conducted thereby at the time of Employee's termination pursuant
to this Agreement. Employee further agrees that during such period he will not
assist or encourage any other person in carrying out any activity that would be
prohibited by the foregoing provisions of this Section 6 if such activity were
carried out by Employee and, in particular, Employee agrees that he will not
induce any employee of Parent or any subsidiary thereof to carry out any such
activity; provided, however, that the "beneficial ownership" by Employee, either
individually or as a member of a "group," as such terms are used in Rule 13d of
the General Rules and Regulations under the Exchange Act, of not more than one
percent (1%) of the voting stock of any publicly held corporation shall not be a
violation of this Agreement. It is further expressly agreed that Parent or any
subsidiary thereof will or would suffer irreparable injury if Employee were to
compete with Parent or any subsidiary or affiliate of Parent in violation of
this Agreement and that Parent would by reason of such competition be entitled
to injunctive relief in a court of appropriate jurisdiction, and Employee
further consents and stipulates to the entry of such injunctive relief in such a
court prohibiting Employee from competing with Parent or any subsidiary or
affiliate of Parent in violation of this Agreement. Employee agrees that the
terms of this paragraph shall not prevent Parent and/or its subsidiaries from
pursuing any other available remedies for any breach or threatened breach
thereof, including but not limited to the recovery of damages from Employee.
Employee and the Company further agree that the provisions of the covenants
contained in this Agreement are reasonable and necessary to protect the
businesses of Parent and its subsidiaries because of Employee's access to
Confidential Information and his material participation in the operation of such
businesses.

                (c) During the period that Employee is receiving payments under
this Agreement or for a period of 12 months following the termination of
Employee's employment if

                                       6
<PAGE>   7

Employee's employment is terminated for Cause or without Good Reason, Employee
shall not, directly or indirectly, influence or attempt to influence suppliers
of Parent or any of its subsidiaries or affiliates, to divert their business to
any competitor of Parent or its subsidiaries.

                (d) Employee recognizes that he will possess confidential
information or trade secrets about other employees of Parent or any subsidiary
thereof relating to their education, experience, skills, abilities, compensation
and benefits, and interpersonal relationships with customers of Parent or any
subsidiary thereof (the "Employee Information"). Employee recognizes that the
Employee Information he will possess is not generally known, is of substantial
value to Parent or any subsidiary thereof in developing its business and in
securing and retaining customers, and will be acquired by him because of his
business position with the Company. Employee agrees that, during the period that
Employee is receiving payments under this Agreement or for a period of 12 months
following the termination of Employee's employment if Employee's employment is
terminated for Cause or without Good Reason, Employee will not, directly or
indirectly, solicit or recruit any employee of Parent or any subsidiary thereof
for the purpose of being employed by Employee or by any competitor of Parent or
any subsidiary thereof on whose behalf he is acting as an agent, representative
or employee and that he will not convey any Employee Information to any other
person.

                (e) If it is determined by a court of competent jurisdiction in
any state that any restriction in this Section 6 is excessive in duration or
scope or is unreasonable or unenforceable under the laws of that state, it is
the intention of the parties that such restriction may be modified or amended by
the court to render it enforceable to the maximum extent permitted by the law of
that state.

            7. Designated Beneficiary. In the event of the death of Employee
while in the employ of the Company, or at any time thereafter during which
amounts remain payable to Employee under Section 5, such payments (other than
the right to continuation of welfare benefits) shall thereafter be made to such
person or persons as Employee may specifically designate (successively or
contingently) to receive payments under this Agreement following Employee's
death by filing a written beneficiary designation with the Company during
Employee's lifetime. Such beneficiary designation shall be in such form as may
be prescribed by the Company and may be amended from time to time or may be
revoked by Employee pursuant to written instruments filed with the Company
during his lifetime. Beneficiaries designated by Employee may be any natural or
legal person or persons, including a fiduciary, such as a trustee or a trust or
the legal representative of an estate. Unless otherwise provided by the
beneficiary designation filed by Employee, if all of the persons so designated
die before Employee on the occurrence of a contingency not contemplated in such
beneficiary designation, then the amounts payable under this Agreement shall be
paid to Employee's estate.

            8. Taxes. All payments to be made to Employee under this Agreement
will be subject to any applicable withholding of federal, state and local income
and employment taxes.

            9. Resolution of Disputes. Notwithstanding anything herein to the
contrary, in the event that there shall be a dispute among the parties arising
out of or relating to this

                                       7
<PAGE>   8

Agreement or the breach thereof, other than, at the option of the Company,
Section 6, the parties agree that such dispute shall be resolved by final and
binding arbitration in New York, New York in accordance Commercial Arbitration
Rules then in effect of JAMS/ENDISPUTE. Depositions may be taken and other
discovery may be obtained during such arbitration proceedings to the same extent
as authorized in civil judicial proceedings. Any award issued as a result of
such arbitration shall be final and binding between the parties thereto, and
shall be enforceable by any court having jurisdiction over the party against
whom enforcement is sought. The fees and expenses of such arbitration
(including, but not limited to, reasonable attorneys' fees) or any action to
enforce an arbitration award shall be paid by the party that does not prevail in
such arbitration.

            10. Attorneys' Fees. Should either party hereto or their successors
retain counsel for the purpose of enforcing, or preventing the breach of, any
provision hereof, including, but not limited to, by instituting any action or
proceeding in arbitration or a court to enforce any provision hereof or to
enjoin a breach of any provision of this Agreement, or for a declaration of such
party's rights or obligations under the Agreement, or for any other remedy,
whether in arbitration or in a court of law, then each party shall bear their
own costs and expenses incurred thereby, including, but not limited to,
reasonable fees and expenses of attorneys and expert witnesses, including costs
of appeal.

            11. Limitation of Liabilities. If Employee is awarded any damages as
compensation for any breach or action related to this Agreement, a breach of any
covenant contained in this Agreement (whether express or implied by either law
or fact), or any other cause of action based in whole or in part on any breach
of any provision of this Agreement, such damages shall be limited to contractual
damages and shall exclude (i) punitive damages, and (ii) consequential and/or
incidental damages (e.g., lost profits and other indirect or speculative
damages). The maximum amount of damages that Employee may recover for any reason
shall be the amount equal to all amounts owed (but not yet paid) to Employee
pursuant to this Agreement through its natural term or through any period for
which severance is due pursuant to Section 5 hereof.

            12. Miscellaneous. This Agreement shall also be subject to the
following miscellaneous considerations:

                (a) Representations and Warranties.

                    (i) Employee represents and warrants to the Company that he
has the authorization, power and right to deliver, execute and fully perform his
