                           LOAN AND SECURITY AGREEMENT


         This LOAN AND SECURITY AGREEMENT is dated as of November 7, 1997 and
entered into among INTENSIVA HEALTHCARE CORPORATION, a Delaware corporation
("Parent"), the Subsidiaries of Parent listed on the signature pages hereof and
each Additional Borrower (as hereinafter defined) (together with Parent,
individually, a "Borrower" and collectively, "Borrowers"), and HELLER FINANCIAL,
INC., a Delaware corporation ("Lender" or "Heller"), with offices at 500 West
Monroe Street, Chicago, Illinois 60661. All capitalized terms used herein are
defined in Section 1 of this Agreement.

         WHEREAS, Borrowers desire that Lender extend a credit facility to
provide working capital financing and to provide funds for other general
corporate purposes; and

         WHEREAS, Borrowers desire to secure their obligations under the Loan
Documents by granting to Lender a security interest in and lien upon certain of
Borrowers' property.

         NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, Borrowers and Lender agree as
follows:


                                     SECTION
1  DEFINITIONS

         1.1 Certain Defined Terms. The following terms used in this Agreement
shall have the following meanings:

         "Acceptable Group" means, at any time, the Persons listed on Schedule
1.1(B).

         "Accounts" means all present and future rights to payment for services
or goods or merchandise sold, accounts, receivables, contract rights, chattel
paper, instruments, documents, rights to payment, reimbursement or settlement
(including cost report settlements) under Medicare, Medicaid, CHAMPUS, CHAMPVA,
other government-sponsored or funded health care programs or insurance or other
medical benefit payments assigned to a Borrower by Patient or pursuant to any
preferred provider, HMO, capitated payment agreements, or other Borrower-Payor
agreements, and General Intangibles relating to each of the foregoing and all
guaranties and security therefor, including, without limitation, all of the
following: all of each Borrower's accounts receivable, lease receivables,
license receivables, all amounts owed to or owned by a Borrower, whether
directly, as assignee, by law or otherwise in respect of, arising or resulting
from the rendition of medical care or other services or the sale or rental of
equipment, supplies or merchandise to Patients, whether or not earned by
performance, and all books of account and records in respect of amounts owing to
a Borrower by Patients, together with all computer programs, applications,
software, and other books and records pertaining to any of the foregoing and all
proceeds of the foregoing. In addition, this definition shall include the
definition of "accounts" as that term is used in the UCC.




<PAGE>   9



         "Additional Borrower" means each Subsidiary of Parent that becomes a
Borrower after the Closing Date pursuant to subsection 2.11.

         "Affiliate" means any Person (other than Lender): (a) directly or
indirectly controlling, controlled by, or under common control with, a Borrower;
(b) directly or indirectly owning or holding five percent (5%) or more of the
total equity interests in a Borrower; or (c) five percent (5%) or more of whose
voting stock or other equity interest having ordinary voting power for the
election of directors or the power to direct or cause the direction of
management is directly or indirectly owned or held by a Borrower; or (d) which
has a senior executive officer who is also a senior executive officer of a
Borrower. For purposes of this definition, "control" (including with correlative
meanings, the terms "controlling", "controlled by" and "under common control
with") means the possession directly or indirectly of the power to direct or
cause the direction of the management and policies of a Person, whether through
the ownership of voting securities or other equity interest, or by contract or
otherwise.

         "Agreement" means this Loan and Security Agreement as it may be
amended, restated, supplemented or otherwise modified from time to time.

         "Asset Disposition" means the disposition, whether by sale, lease,
transfer, loss, damage, destruction, condemnation or otherwise, of any or all of
the assets of a Borrower or any of its Subsidiaries other than sales of
Inventory in the ordinary course of business.

         "Availability" means, at any time of determination thereof, the Maximum
Revolving Loan Amount minus the aggregate outstanding principal balance of the
Revolving Loan.

         "Base Rate" means a variable rate of interest per annum equal to the
higher of (a) the rate of interest from time to time published by the Board of
Governors of the Federal Reserve System as the "Bank Prime Loan" rate in Federal
Reserve Statistical Release H.15(519) entitled "Selected Interest Rates" or any
successor publication of the Federal Reserve System reporting the Bank Prime
Loan rate or its equivalent, or (b) the Federal Funds Effective Rate. The
statistical release generally sets forth a Bank Prime Loan rate for each
Business Day. In the event the Board of Governors of the Federal Reserve System
ceases to publish a Bank Prime Loan rate or its equivalent, the term "Base Rate"
shall mean a variable rate of interest per annum equal to the highest of the
"prime rate", "reference rate", "base rate", or other similar rate announced
from time to time by any of Bankers Trust Company or The Chase Manhattan Bank or
their successors (with the understanding that any such rate may merely be a
reference rate and may not necessarily represent the lowest or best rate
actually charged to any customer by any such bank).

         "Borrowers" has the meaning assigned to that term in the preamble to
this Agreement.

         "Borrowing Base" means, as of any date of determination, an amount
equal to ninety percent (90%) of the Estimated Insured Value of outstanding
Eligible Accounts, less the aggregate Lease Reserve and, subject to the
limitations set forth in subsection 2.12, such other reserves as Lender in its
reasonable discretion elects to establish. In furtherance of the foregoing and
not in limitation


                                        2

<PAGE>   10



thereof, Lender shall reserve for all credit balances with respect to Accounts
reflected on the books and records of a Borrower and any other credits that
Lender is or becomes aware of through any source.

         "Business Day" means any day excluding Saturday, Sunday and any day
which is a legal holiday under the laws of the States of Illinois, Pennsylvania

                                       12

<PAGE>   20



to exceed at any time the Maximum Revolving Loan Amount. Amounts borrowed under
this subsection 2.1(A) may be repaid and reborrowed at any time prior to the
earlier of (i) the termination of the Revolving Loan Commitment pursuant to
subsection 8.3 or (ii) the Termination Date. Lender shall have no obligation to
make a Revolving Advance to the extent any requested advance would cause the
Revolving Loan (after giving effect to any immediate application of the proceeds
thereof) to exceed the Maximum Revolving Loan Amount.

                  (B)      Eligible Accounts.

         "Eligible Accounts" means, as at any date of determination, the
aggregate of all Accounts that Lender, in its reasonable judgment, deems to be
eligible for borrowing purposes. Without limiting the generality of the
foregoing, unless otherwise agreed by Lender, the following Accounts are not
Eligible Accounts:

                           (1) Accounts that are not Commercial Accounts or
         Government Accounts;

                           (2) Accounts outstanding more than one hundred twenty
         (120) days from the billing date of such Accounts;

                           (3) Accounts for which the Payor is located outside
         the United States;

                           (4) Accounts for which Lender has notified Borrowers
         that the Payor does not have satisfactory credit or financial standing
         (as determined in the reasonable discretion of Lender);

                           (5) Accounts in which Lender does not have a valid,
         first priority and fully perfected security interest;

                           (6) Accounts subject to any Lien except those in
         favor of Lender;

                           (7) Accounts (other than Eligible Unbilled Accounts)
         that have not yet been billed;

                           (8) Accounts with respect to which Payor is a Person
         to whom a Borrower is indebted, provided, however, that such Accounts
         shall only be ineligible as to that portion of the Accounts which is
         less than or equal to the amount owed by such Borrower to such Person;

                           (9) Accounts for which the Payor is an Affiliate of a
         Borrower;

                           (10) Accounts for which the Payor notification
         letters required pursuant to subsection 3.1 have not been sent;



                                       13

<PAGE>   21



                           (11) Accounts due from one commercial Payor if fifty
         percent (50%) or more of the aggregate Accounts due from such
         commercial Payor are outstanding more than 120 days from the billing
         date;

                           (12) That part of Accounts consisting of cost report
         and other settlements due to a Borrower from government agencies,
         regardless of whether such amounts are the result of interim or final
         cost reports; and

                           (13) Accounts evidenced by an "instrument" or
         "chattel paper" as defined in the UCC not in the possession of Lender.

                  (C) Borrowing Mechanics. On any day when Borrowers desire to
borrow under this subsection 2.1, Borrowers shall give Lender telephonic notice
of the proposed borrowing by 11:00 a.m. (Chicago time) on the Funding Date,
which notice (a "Notice of Borrowing") shall also specify the proposed Funding
Date (which shall be a Business Day). Lender shall not incur any liability to
Borrowers for acting upon any telephonic notice Lender believes in good faith to
have been given by a duly authorized officer or other person authorized to
borrow on behalf of Borrowers or for otherwise acting in good faith under this
subsection 2.1(C). Lender will not make any advance pursuant to any telephonic
notice unless Lender has also received the most recent Collateral Report and all
other documents required under subsection 5.1(E) by 11:00 a.m. (Chicago time).
Each advance made to Borrowers under the Revolving Loan shall be deposited by
wire transfer in immediately available funds in such account as Borrowers may
from time to time designate to Lender in writing. Unless payment is otherwise
timely made by Borrowers, the becoming due of any amount required to be paid
under this Agreement or any of the other Loan Documents as principal, accrued
interest and fees shall be deemed irrevocably to be a request by Borrowers for a
Revolving Loan on the due date of, and in the amount required to pay, such
principal, accrued interest and fees, and the proceeds of each such Revolving
Loan if made by Lender shall be disbursed by Lender by way of direct payment of
the relevant obligation.

         (D) Evidence of Revolving Loan Obligations. Each Revolving Advance
shall be evidenced by this Agreement and notations made from time to time by
Lender in its books and records, including computer records. Lender's books and
records shall constitute presumptive evidence, absent manifest error, of the
accuracy of the information contained therein. Failure by the Lender to make any
such notation or record shall not affect the obligations of Borrowers to Lender
with respect to the Revolving Loans.

         2.2      Interest

                  (A) Rate of Interest. The Loans and all other Obligations
shall bear interest from the date such Loans are made or such other Obligations
become due to the date paid at a rate per annum equal to either (i) the Base
Rate plus one-quarter of one percent (0.25%) (the "Regular Rate"), or (ii) LIBOR
plus two and one-half percent (2.50%) (the "LIBOR Rate"), as selected by
Borrowers in accordance with the provisions hereof; provided, however, that if
at any time the LIBOR Rate is incapable of determination, then the Loans and all
other Obligations shall bear interest at the Regular


                                       14

<PAGE>   22



Rate. The Loans and all other Obligations initially shall bear interest at the
Regular Rate, provided that Borrowers may at any time after the Closing Date
convert the Interest Rate to a rate based on the LIBOR Rate as set forth above
by delivering to Lender not less than two (2) Business Days prior written notice
(a "Notice of Election"). At any time that Borrowers elect for the Loans and the
other Obligations to bear interest at the LIBOR Rate, such Interest Rate shall
remain fixed during the period commencing on the date that such LIBOR Rate is to
be effective (as set forth in the Notice of Election) through and including the
date which is thirty (30) days after the date that such LIBOR Rate is to be
effective. Thereafter, the Loans and the other Obligations shall bear interest
at the Regular Rate unless Borrowers elect that the Loans and the other
Obligations shall bear interest at the LIBOR Rate by properly delivering a
Notice of Election. Each Interest Rate election shall be applicable to all
outstanding Loans and other Obligations.

         After the occurrence and during the continuance of an Event of Default,
at Lender's option, the Loans and all other Obligations shall bear interest at a
rate per annum equal to two percent (2%) plus the applicable Interest Rate (the
"Default Rate").

                  (B) Computation and Payment of Interest. Interest on the Loans
and all other Obligations shall be computed on the daily principal balance on
the basis of a 360 day year for the actual number of days elapsed in the period
during which it accrues and shall be payable monthly in arrears on the first day
of each month, on the date of any prepayment of Loans, and at maturity, whether
by acceleration or otherwise. Any publicly announced change in the Base Rate
shall result in an adjustment to the Regular Rate on the day such change takes
effect. The LIBOR Rate shall remain fixed during the period commencing on the
date that such LIBOR Rate is to be effective (as set forth in the Notice of
Election) through and including the date which is thirty (30) days after the
date that such LIBOR Rate is to be effective. Thereafter, the Loans and the
other Obligations shall bear interest at the Regular Rate unless Borrowers elect
that the Loans and the other Obligations shall bear interest at the LIBOR Rate
by properly delivering a Notice of Election. Each Interest Rate election shall
be applicable to all outstanding Loans and other Obligations. In computing
interest on any Loan, the date of funding of the Loan shall be included; and the
date of payment of such Loan shall be excluded; provided that if a Loan is
repaid on the same day on which it is made, one day's interest shall be paid on
that Loan.

                  (C) Interest Laws. Notwithstanding any provision to the
contrary contained in this Agreement or any other Loan Document, Borrowers shall
not be required to pay, and Lender shall not be permitted to collect, any amount
of interest in excess of the maximum amount of interest permitted by applicable
law ("Excess Interest"). If any Excess Interest is provided for or determined by
a court of competent jurisdiction to have been provided for in this Agreement or
in any other Loan Document, then in such event: (1) the provisions of this
subsection shall govern and control; (2) no Borrower shall be obligated to pay
any Excess Interest; (3) any Excess Interest that Lender may have received
hereunder shall be, at Lender's option, (a) applied as a credit against the
outstanding principal balance of the Obligations or accrued and unpaid interest
(not to exceed the maximum amount permitted by law), (b) refunded to the payor
thereof, or (c) any combination of the foregoing; (4) the interest rate(s)
provided for herein shall be automatically reduced to the maximum lawful rate
allowed from time to time under applicable law (the "Maximum Rate"), and


                                       15

<PAGE>   23



this Agreement and the other Loan Documents shall be deemed to have been and
shall be, reformed and modified to reflect such reduction; and (5) no Borrower
shall have any action against Lender for any damages arising out of the payment
or collection of any Excess Interest. Notwithstanding the foregoing, if for any
period of time interest on any Obligations is calculated at the Maximum Rate
rather than the applicable rate under this Agreement, and thereafter such
applicable rate becomes less than the Maximum Rate, the rate of interest payable
on such Obligations shall remain at the Maximum Rate until Lender shall have
received the amount of interest which Lender would have received during such
period on such Obligations had the rate of interest not been limited to the
Maximum Rate during such period.

         2.3      Fees.

                  (A) Closing Fee and Activation Fee. Borrowers shall pay to
Lender on the Closing Date a closing fee in the amount of $75,000; upon an
increase in the amount of the Revolving Loan Commitment as provided in the
definition thereof, Borrowers shall pay to Lender an activation fee in the
amount of $75,000.

                  (B) Unused Line Fees. Borrowers shall pay to Lender (i) a fee
in an amount equal to the Activated Portion of the Revolving Loan Commitment
less the average daily balance of the Revolving Loan during the preceding month
multiplied by one-half percent (0.50%) per annum, such fee to be calculated on
the basis of a 360 day year for the actual number of days elapsed and to be
payable monthly in arrears on the first day of the first month following the
Closing Date and the first day of each month thereafter, and (ii) a monthly fee
of $1,041.67 until such time as the Revolving Loan Commitment is increased from
$10,000,000 to $20,000,000 in accordance with the terms of this Agreement, such
fee to be payable monthly in arrears on the first day of the first month
following the Closing Date and the first day of each month thereafter.

                  (B) Prepayment Fees. If Borrowers voluntarily prepay the
Obligations prior to the Termination Date (other than voluntary prepayments of
the Revolving Loan which do not terminate the Revolving Loan Commitment and
other than a voluntary prepayment of the Revolving Loan and termination of the
Revolving Loan Commitment within sixty (60) days following the date on which
Lender makes a demand for payment under subsection 2.8 or 2.9(B)), Borrowers at
the time of prepayment shall pay to Lender, as compensation for the costs of
being prepared to make funds available to Borrowers under this Agreement, and
not as a penalty, an amount determined by multiplying the percentage set forth
below by the amount of the Revolving Loan Commitment: two percent (2.00%) upon a
prepayment during the first Loan Year; and one percent (1.00%) upon a prepayment
during the second Loan Year. Notwithstanding the foregoing, Borrower may at any
time prepay the Loans in full and terminate this Agreement, in accordance with
subsection 2.4(C) hereof, and shall not be obligated to pay the prepayment fee
referred to in the immediately preceding sentence as a result of such prepayment
if at the time of such prepayment Borrowers and Heller have not entered into an
amendment to this Agreement, amending the definition of "Eligible Unbilled
Accounts."



                                       16

<PAGE>   24



                  (C) Collateral Management Fee. Borrowers shall pay to Lender,
without demand, in addition to any interest and other fees due under this
Agreement, an aggregate collateral management fee at the rate of $24,000 per
annum. Said fee shall be payable monthly in arrears on the first day of each
month, commencing on the first day of the month following the Closing Date, and
on the Termination Date, except that the amount of the collateral management fee
payable on the Termination Date in respect of the month in which the Termination
Date occurs shall be pro rated based on the number of days that this Agreement
is in effect during such final month.

                  (D) Audit Fees. Borrowers agree to pay Lender an audit fee
equal to $750 per auditor per day or any portion thereof (excluding all full
days spent by Lender traveling to or from Borrowers' locations), together with
out-of-pocket expenses.

                  (E) Other Fees and Expenses. Borrowers shall pay to Lender,
for its own account, all charges for returned items and all other bank charges
incurred by Lender, as well as Lender's standard wire transfer charges for each
wire transfer made under this Agreement.

         2.4      Payments and Prepayments.

                  (A) Manner and Time of Payment. In its sole discretion, Lender
may charge interest and other amounts payable hereunder to the Revolving Loan,
all as set forth on Lender's books and records. If Lender elects to bill
Borrowers for any amount due hereunder, such amount shall be immediately due and
payable with interest thereon as provided herein. All payments made by Borrowers
with respect to the Obligations shall be made without deduction, defense, setoff
or counterclaim. All payments to Lender hereunder shall, unless otherwise
directed by Lender, be made in accordance with subsection 5.6. Proceeds remitted
to Lender's Account shall be credited to the Obligations on the Business Day
such proceeds were received, provided, however, for the purpose of calculating
interest on the Obligations, such funds shall be deemed received on the first
Business Day thereafter.

                  (B) Mandatory Prepayment. At any time that the Revolving Loan
exceeds the Maximum Revolving Loan Amount, Borrowers shall immediately repay the
Revolving Loan to the extent necessary to reduce the principal balance to an
amount that is equal to or less than the Maximum Revolving Loan Amount.

                  (C) Voluntary Prepayments and Repayments. Borrowers'
Obligations may only be prepaid or repaid in full and not in part. Borrowers
may, at any time, upon not less than three (3) Business Days' prior written
notice to Lender, terminate the Revolving Loan Commitment.

                  (D) Payments on Business Days. Whenever any payment to be made
hereunder shall be stated to be due on a day that is not a Business Day, the
payment may be made on the next succeeding Business Day and such extension of
time shall be included in the computation of the amount of interest or fees due
hereunder.



                                       17

<PAGE>   25



         2.5 Term of this Agreement. This Agreement shall be effective until
October 31, 2000 (the "Termination Date"). The Revolving Loan Commitment shall
(unless earlier terminated) terminate upon the earlier of (i) the occurrence of
an event specified in subsection 8.3 or (ii) the Termination Date. Upon
termination in accordance with subsection 8.3 or on the Termination Date, all
Obligations shall become immediately due and payable without notice or demand.
Notwithstanding any termination, until all Obligations have been fully paid and
satisfied, Lender shall be entitled to retain security interests in and liens
upon all Collateral, and even after payment of all Obligations hereunder,
Borrowers' obligation to indemnify Lender in accordance with the terms hereof
shall continue.

         2.6 Statements. Lender shall render a monthly statement of account to
Borrowers within twenty (20) days after the end of each month. Such statement of
account shall constitute an account stated unless Borrowers make written
objection thereto within thirty (30) days from the date such statement is mailed
to Borrowers. Borrowers promise to pay all of the Obligations as such amounts
become due or are declared due pursuant to the terms of this Agreement.

         2.7 Grant of Security Interest. To secure the payment and performance
of the Obligations, including all renewals, extensions, restructurings and
refinancings of any or all of the Obligations, each Borrower hereby grants to
Lender a continuing security interest, lien and mortgage in and to all right,
title and interest of such Borrower in the following property of such Borrower,
whether now owned or existing or hereafter acquired or arising and regardless of
where located (all being collectively referred to as the "Collateral"): (A)
Accounts; (B) Inventory, (C) General Intangibles; (D) instruments (as defined in
the UCC); (E) proceeds of Loans made hereunder; (F) documents (as defined in the
UCC) or other receipts covering, evidencing, or representing goods; (G)
investment property (as defined in the UCC); (H) chattel paper (as defined in
the UCC); (I) fixtures (as defined in the UCC); (J) Equipment (other than leased
Equipment); (K) Intellectual Property; (L) monies, securities and other property
now or hereafter held or received by, or in transit to Lender from or for such
Borrower, whether for safekeeping, pledge, custody, transmission, collection or
otherwise, and all of such Borrower's deposits and credit balances in Lender's
possession; (M) all deposit accounts of such Borrower maintained with any bank
or financial institution; (N) all cash and other monies and property of Borrower
in the possession or under the control of Lender or any participant; (O) all
books, records, ledger cards, files, correspondence, computer programs, tapes,
disks and related data processing software that at any time evidence or contain
information relating to any of the property described above or are otherwise
necessary or helpful in the collection thereof or realization thereon; and (P)
proceeds of all or any of the property described above, including, without
limitation, the proceeds of any insurance policies covering any of the above
described property. Notwithstanding the foregoing, the Collateral shall not
include any computer software that is licensed to a Borrower if the license of
such software prohibits the granting of a security interest therein. Recourse to
the collateral security herein provided shall not be required, and Borrower
shall at all times herein remain liable for the payment and performance of all
of the Obligations as provided herein.

         2.8 Capital Adequacy and Other Adjustments. In the event Lender shall
have determined that the adoption after the date hereof of any law, treaty,
governmental (or quasi-governmental) rule,


                                       18

<PAGE>   26



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 Borrowers shall from time to time
within fifteen (15) days after notice and demand from Lender (together with the
certificate referred to in the next sentence) pay to Lender additional amounts
sufficient to compensate such 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 Lender to Borrowers shall, absent manifest error, be presumptively
correct and binding for all purposes.

         2.9      Taxes.

                  (A) No Deductions. Any and all payments or reimbursements made
hereunder 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; excluding, however, the following: taxes imposed on the
net income of Lender by the jurisdiction under the laws of which Lender is
organized or doing business or any political subdivision thereof and taxes
imposed on its net income by the jurisdiction of Lender's applicable lending
office or any political subdivision thereof (all such taxes, levies, imposts,
deductions, charges or withholdings and all liabilities with respect thereto
excluding such taxes imposed on net income, herein "Tax Liabilities"). If
Borrowers shall be required by law to deduct any such Tax Liabilities 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
Closing Date, (i) any changes in any existing law, regulation, treaty or
directive or in the interpretation or application thereof, (ii) any new law,
regulation, treaty or directive enacted or any interpretation or application
thereof, or (iii) compliance by Lender with any request or directive (whether or
not having the force of law) from any governmental authority, agency or
instrumentality:

                      (1) does or shall subject Lender to any tax of any kind
whatsoever with respect to this Agreement, the other Loan Documents or any Loans
made hereunder, 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 or other fees payable hereunder or changes in the rate of tax on
the overall net income of Lender); or



                                       19

<PAGE>   27



                      (2) 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 any Loan hereunder, or to reduce any
amount receivable hereunder, then, in any such case, Borrowers 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 other
Loan Documents. If Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify Borrowers 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 Borrowers shall, absent manifest error, be presumptively correct and
binding for all purposes.

         2.10     Joint and Several Obligations.

                  (A) All of the Obligations shall be the joint and several
obligation of Parent and the other Borrowers. The Obligations of each Borrower
hereunder shall not be released, discharged or otherwise affected by:

                      (1) any extension, renewal, settlement, compromise, waiver
or release in respect of any Obligation of any other Borrower or the Collateral
therefor under this Agreement or the other Loan Documents;

                      (2) any modification or amendment of or supplement to this
Agreement or the other Loan Documents;

                      (3) any change in the corporate or partnership existence,
structure or ownership of any other Borrower, or any insolvency, bankruptcy,
reorganization or other similar proceeding affecting any other Borrower or its
Collateral or its assets;

                      (4) the existence of any claim, set-off or other rights
that such Borrower may have at any time against any other Borrower, Lender or
any other Person, whether in connection herewith or any unrelated transactions,
provided that nothing herein shall prevent the assertion of any such claim by
separate suit or compulsory counterclaim;

                      (5) any invalidity or unenforceability relating to or
against any Borrower for any reason of any provision or all of this Agreement or
the other Loan Documents, or any provision of applicable law or regulation
purporting to prohibit the payment by any Borrower of any amount payable by it
under this Agreement or the other Loan Documents; or

                      (6) any other act or omission to act or delay of any kind
by any Borrower, Lender or any other Person or any other circumstance whatsoever
that might, but for the provisions of this paragraph, constitute a legal or
equitable discharge of such Borrower's obligations under this Agreement or the
other Loan Documents.



                                       20

<PAGE>   28



                  (B) Each Borrower's Obligations under this subsection 2.10
shall remain in full force and effect until all Obligations shall have been paid
in full and this Agreement and the other Loan Documents shall have terminated in
accordance with their terms. If at any time any payment of any amount payable by
any Borrower under this Agreement or the other Loan Documents is rescinded or
must be otherwise restored or returned upon the insolvency, bankruptcy or
reorganization of such Borrower or otherwise, each Borrower's Obligations under
this subsection 2.10 with respect to such payment shall be revived and continued
in full force and effect.

                  (C) In the event that the demand for payment of any amount
payable by any Borrower under this Agreement or the other Loan Documents is
stayed upon the insolvency, bankruptcy or reorganization of such Borrower, all
such amounts otherwise subject to acceleration under the terms of this Agreement
or the other Loan Documents shall nonetheless be payable by each Borrower
hereunder forthwith upon demand by Lender.

                  (D) Each Borrower hereby irrevocably waives and releases each
other Borrower from all "claims" (as defined in Section 101(4) of the Bankruptcy
Code) to which such Borrower is or would be entitled by virtue of the guaranty
of the Obligations of any other Borrower or the performance of such Borrower's
obligations under this subsection 2.10, including, without limitation, any right
of subrogation (whether contractual, under Section 509 of the Bankruptcy Code or
otherwise), reimbursement, contribution, exoneration or other similar right, or
indemnity, or any right of recourse to security for any of the Obligations.

         2.11 Additional Borrowers. Subsidiaries of Parent formed or acquired
after the Closing Date may, upon the request of Parent and with the consent of
Lender (which may be granted or withheld in Lender's sole and absolute
discretion), become Borrowers hereunder, subject to the satisfaction of the
following:

                  (A) Borrowers and such Subsidiary shall deliver to Lender duly
executed amendments to this Agreement and the Pledge Agreements and such other
documents as Lender shall reasonably request, each in form and substance
reasonably satisfactory to Lender, evidencing that such Subsidiary is a Borrower
hereunder, that such Subsidiary has granted to Lender a first priority,
perfected security interest in its Collateral as security for the Obligations
and that all of the issued and outstanding stock of such Subsidiary is pledged
to Lender as security for the Obligations;

                  (B) Lender shall have received favorable lien search reports
with respect to such Subsidiary;

                  (C) Borrowers and such Subsidiary shall deliver to Lender duly

files and information of each Borrower to the same extent that Lender protects
its own proprietary information, and will not disclose such information to
others other than as required for the processing and collection of Accounts and

shall establish one or more lockboxes and one or more depository accounts in
such Borrower's name with such collecting banks as are acceptable to Lender

Accounts) to remit all payments on such Accounts either to a lockbox (in the
case of payments by check) or a depository account (in the case of payment by
wire transfer or other funds transfer mechanism) established pursuant to this
subsection 5.6(A). Each such collecting bank shall acknowledge and agree, in a
manner satisfactory to Lender, that all checks and other items of payment
received in each lockbox established with such collecting bank shall be
deposited in the applicable depository account, that Lender shall have sole and
exclusive dominion and control over such depository account and all funds
therein and that such collecting bank shall have no right of setoff against such
depository account. Each Borrower hereby agrees that all payments made to any
such lockbox or depository account or otherwise received by Lender and

<PAGE>   41



Accounts or other Collateral (other than Government Accounts) are the sole and
exclusive property of Lender. Each Borrower shall irrevocably instruct each such
collecting bank that it shall wire transfer to Lender on each business day all
collected funds in the applicable depository account. Each Borrower, and any of
its Affiliates, employees, agents or other Persons acting for or in concert with
a Borrower, shall, acting as trustee for Lender, receive, as the sole and
exclusive property of Lender, any monies, checks, notes, drafts or any other
payments relating to and/or proceeds of Accounts or other Collateral (other than
Government Accounts) that come into the possession or under the control of such
Borrower or any of such Borrower's Affiliates, employees, agents or other
Persons acting for or in concert with such Borrower, and immediately upon
receipt thereof, such Borrower or such Persons shall remit the same or cause the
same to be remitted, in kind, to a depository account established pursuant to
this subsection 5.6(A).

                  (B) Government Accounts. Each Borrower shall forward to
Lender, an amount equal to all remittances or other payments received by such
Borrower representing payments of Government Accounts within one (1) day of
receipt of such remittances or payments. Each Borrower shall establish a lockbox
or other depository account in its name to which it shall direct payment of
Government Accounts. Each Borrower shall instruct the bank at which such lockbox
is maintained to forward the proceeds of such lockbox or depository account to
Lender each business day, and no Borrower shall change such instructions without
delivering at least ten (10) days prior written notice to Lender, provided that
if such new instructions direct payment of such proceeds to a Person other than
Lender, then Lender shall have the right to declare the Obligations due and
payable and to terminate this Agreement by delivering written notice of such
election to Borrowers. To the extent Lender receives from any Payor any payments
or other remittances relating to Government Accounts, Lender shall deposit such
amounts to a depository account of the appropriate Borrower established pursuant
to this subsection 5.6(B).

         5.7 Endorsement. Each Borrower hereby constitutes and appoints Lender
and all Persons designated by Lender for that purpose as such Borrower's true
and lawful attorney-in-fact, with power to endorse such Borrower's name to any
of the items of payment or proceeds described in subsection 5.6 above and all
proceeds of Collateral that come into Lender's possession or under Lender's
control. Both the appointment of Lender as each Borrower's attorney and Lender's
rights and powers are coupled with an interest and are irrevocable until payment
in full and complete performance of all of the Obligations.

         5.8 Corporate Existence. Each Borrower will, and will cause each of its
Subsidiaries to, at all times preserve and keep in full force and effect its
corporate existence and all rights and franchises material to its business. Each
Borrower will promptly notify Lender of any change in its or its Subsidiaries'
ownership or corporate structure.

         5.9 Payment of Taxes. Each Borrower will, and will cause each of its
Subsidiaries to, pay all taxes, assessments and other governmental charges
imposed upon it or any of its properties or assets or with respect to any of its
franchises, business, income or property before any penalty accrues thereon
provided that no such tax need be paid if a Borrower or one of its Subsidiaries
is contesting same in good faith by appropriate proceedings promptly instituted
and diligently


                                       34

<PAGE>   42



conducted and if a Borrower or such Subsidiary has established appropriate
reserves as shall be required in conformity with GAAP.

         5.10 Maintenance of Properties; Insurance. Each Borrower will maintain
or cause to be maintained in good repair, working order and condition all
material properties used in the business of such Borrower and its Subsidiaries
and will make or cause to be made all appropriate repairs, renewals and
replacements thereof. Each Borrower will maintain or cause to be maintained,
with financially sound and reputable insurers, public liability and property
damage insurance with respect to its business and properties and the business
and properties of its Subsidiaries against loss or damage of the kinds
customarily carried or maintained by corporations of established reputation
engaged in similar businesses and in amounts acceptable to Lender. Borrowers
shall cause Lender to be named as loss payee on all insurance policies relating
to any Collateral and as additional insured under all liability policies, in
each case pursuant to appropriate endorsements in form and substance
satisfactory to Lender and shall collaterally assign to Lender as security for
the payment of the Obligations all business interruption insurance of each
Borrower. In the event Borrowers fail to provide Lender with evidence of the
insurance coverage required by this Agreement, Lender may, but is not required
to, purchase insurance at Borrowers' expense to protect Lender's interests in
the Collateral. This insurance may, but need not, protect Borrowers' interests.
The coverage purchased by Lender may not pay any claim made by a Borrower or any
claim that is made against a Borrower in connection with the Collateral.
Borrowers may later cancel any insurance purchased by Lender, but only after
providing Lender with evidence that Borrowers have obtained insurance as
required by this Agreement. If Lender purchases insurance for the Collateral,
Borrowers will be responsible for the costs of that insurance, including
interest and other charges imposed by Lender in connection with the placement of
the insurance, until the effective date of the cancellation or expiration of the
insurance. The costs of the insurance may be added to the Obligations. The costs
of the insurance may be more than the cost of insurance Borrowers are able to
obtain on their own.

         5.11 Compliance with Laws. Each Borrower will, and will cause each of
its Subsidiaries to, comply with the requirements of all applicable laws, rules,
regulations and orders of any governmental authority as now in effect and which
may be imposed in the future in all jurisdictions in which such Borrower or any
of its Subsidiaries is now doing business or may hereafter be doing business,
other than those laws the noncompliance with which would not have a Material
Adverse Effect.

         5.12 Further Assurances. Each Borrower shall, and shall cause each of
its Subsidiaries to, from time to time, execute such guaranties, financing or
continuation statements, documents, security agreements, reports and other
documents or deliver to Lender such instruments, certificates of title or other
documents as Lender at any time may reasonably request to evidence, perfect or
otherwise implement the guaranties and security for repayment of the Obligations
provided for in the Loan Documents. At Lender's request, each Borrower shall
cause any Subsidiaries of such Borrower promptly to guaranty the Obligations and
to grant to Lender security interests in the real, personal and mixed property
of such Subsidiary to secure the Obligations.

         5.13 Use of Proceeds and Margin Security. Borrowers shall use the
proceeds of all Loans for proper business purposes (as described in the recitals
to this Agreement) consistent with all applicable laws, statutes, rules and
regulations. No portion of the proceeds of any Loan shall be used by a Borrower
or any of its Subsidiaries for the purpose of purchasing or carrying of margin
stock within the meaning of Regulation G or Regulation U, or in any manner that
might cause the borrowing or the application of such proceeds to violate
Regulation T or Regulation X or any other regulation of the Board of Governors
of the Federal Reserve System, or to violate the Exchange Act.

         5.14 Implementation of Electronic Data Backup System. Within thirty

backups of all patient demographic, "billed to" party, accessions records, and
other types and categories of billing and testing data maintained by Borrowers,
which data shall be at least as extensive as that processed and stored as of the
Closing Date by Borrowers' software program. Borrowers shall irrevocably
instruct the Backup Provider, pursuant to an agreement in form and substance
satisfactory to Lender, to permit and facilitate Lender's access to and
retrieval of all such data upon Lender's request therefor or at least on a
weekly basis.

         5.15 Landlord Agreement. Within thirty (30) days after the Closing

within one hundred twenty (120) days; and (2) could result in the confiscation
or forfeiture of any material portion of the Collateral.

         8.2 Suspension of Revolving Loan Commitment. Upon the occurrence of any
Default or Event of Default, notwithstanding any grace period or right to cure,
Lender, without notice or demand, may immediately cease making additional Loans
and the Revolving Loan Commitment shall be suspended; provided that, in the case
of a Default, if the subject condition or event is waived or cured within any
applicable grace or cure period, the Revolving Loan Commitment shall be
reinstated.

         8.3 Acceleration. Upon the occurrence of any Event of Default described
in the foregoing subsections 8.1(G) or 8.1(H), all Obligations shall
automatically become immediately due and payable, without presentment, demand,
protest or other requirements of any kind, all of which are hereby expressly
waived by Borrowers, and the Revolving Loan Commitment shall thereupon
terminate. Upon the occurrence and during the continuance of any other Event of
Default, Lender may, by written notice to Borrowers, declare all or any portion
of the Obligations to be, and the same shall forthwith become, immediately due
and payable and the Revolving Loan Commitment shall thereupon terminate.

         8.4 Remedies. If any Event of Default shall have occurred and be
continuing, in addition to and not in limitation of any rights or remedies
available to Lender at law or in equity, Lender may exercise in respect of the
Collateral, in addition to all other rights and remedies provided for herein or
otherwise available to it, all the rights and remedies of a secured party on
default under the UCC (whether or not the UCC applies to the affected
Collateral) and may also (a) notify any or all obligors on the Accounts to make
all payments directly to Lender; (b) require Borrowers to, and Borrowers hereby
agree that they will, at their expense and upon request of Lender forthwith,
assemble all or part of the Collateral as directed by Lender and make it
available to Lender at a place to be designated by Lender which is reasonably
convenient to both parties; (c) withdraw all cash in each blocked account
established pursuant to subsection 5.6 and apply such monies in payment of the
Obligations in the manner provided in subsection 8.7; (d) without notice or
demand or legal process, enter upon any premises of a Borrower and take
possession of the Collateral; and (e) without notice except as specified below,
sell the Collateral or any part thereof in one or more parcels at public or
private sale, at any of the Lender's offices or elsewhere, at such time or
times, for cash, on credit or for future delivery, and at such price or prices
and upon such other terms as Lender may deem commercially reasonable. Each
Borrower agrees that, to the extent notice of sale shall be required by law, at
least ten (10) days notice to Borrowers of the time and place of any public sale
or the time after which any private sale is to be made shall constitute
reasonable notification. At any sale of the Collateral, if permitted by law,
Lender may bid (which bid may be, in whole or in part, in the form of
cancellation of indebtedness) for the purchase of the Collateral or any portion
thereof for the account of Lender. Lender shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. Borrowers
shall remain liable for any


                                       44

<PAGE>   52



deficiency. Lender may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. To
the extent permitted by law, each Borrower hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter enacted. Lender shall not be required to proceed against
any Collateral but may proceed against Borrowers directly.

         8.5 Appointment of Attorney-in-Fact. Each Borrower hereby constitutes
and appoints Lender as such Borrower's attorney-in-fact with full authority in
the place and stead of such Borrower and in the name of such Borrower, Lender or
otherwise, from time to time in Lender's discretion while an Event of Default is
continuing to take any action and to execute any instrument that Lender may deem
necessary or advisable to accomplish the purposes of this Agreement, including:
(a) to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Collateral; (b) to adjust, settle or compromise the amount or payment
of any Account, or release wholly or partly any customer or obligor thereunder
or allow any credit or discount thereon; (c) to receive, endorse, and collect
any drafts or other instruments, documents and chattel paper, in connection with
clause (a) above; (d) to file any claims or take any action or institute any
proceedings that Lender may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce the rights of Lender with respect
to any of the Collateral; (e) to sign and endorse any invoices, assignments,
verifications and notices in connection with Accounts and other documents
relating to the Collateral; (f) prepare, file and sign such Borrower's name on
any proof of claim in bankruptcy, cost report (final or interim) or other
similar document against a Payor; and (g) notify the postal authorities of any
change of the address for delivery of such Borrower's mail with respect to
Accounts to an address designated by Lender, and open and dispose of all mail
with respect to Accounts addressed to such Borrower. The appointment of Lender
as each Borrower's attorney and Lender's rights and powers are coupled with an
interest and are irrevocable until payment in full and complete performance of
all of the Obligations.

         8.6 Limitation on Duty of Lender with Respect to Collateral. Beyond the
safe custody thereof, Lender shall have no duty with respect to any Collateral
in its possession or control (or in the possession or control of any agent or
bailee) or with respect to any income thereon or the preservation of rights
against prior parties or any other rights pertaining thereto. Lender shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which Lender accords its own property. Lender shall
not be liable or responsible for any loss or damage to any of the Collateral, or
for any diminution in the value thereof, by reason of the act or omission of any
warehouseman, carrier, forwarding agency, consignee or other agent or bailee
selected by Lender in good faith.

         8.7 Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, (a) each Borrower irrevocably waives the
right to direct the application of any and all payments at any time or times
thereafter received by Lender from or on behalf of a Borrower, and each Borrower
hereby irrevocably agrees that Lender shall have the continuing exclusive right
to


                                       45

<PAGE>   53



apply and to reapply any and all payments received at any time or times after
the occurrence and during the continuance of an Event of Default against the
Obligations in such manner as Lender may deem advisable notwithstanding any
previous entry by Lender upon any books and records and (b) the proceeds of any
sale of, or other realization upon, all or any part of the Collateral shall be
applied: first, to all fees, costs and expenses incurred by Lender with respect
to this Agreement, the other Loan Documents or the Collateral; second, to all
fees due and owing to Lender; third, to accrued and unpaid interest on the
Obligations; fourth, to the principal amounts of the Obligations outstanding;
and fifth, to any other indebtedness or obligations of Borrowers owing to
Lender.

         8.8 Waivers, Non-Exclusive Remedies. No failure on the part of Lender
to exercise, and no delay in exercising and no course of dealing with respect
to, any right under this Agreement or the other Loan Documents shall operate as
a waiver thereof; nor shall any single or partial exercise by Lender of any
right under this Agreement or any other Loan Document preclude any other or
further exercise thereof or the exercise of any other right. The rights in this
Agreement and the other Loan Documents are cumulative and are not exclusive of
any other remedies provided by law.


                             SECTION 9 MISCELLANEOUS

         9.1 Assignments and Participations. Lender may assign its rights and
delegate its obligations under this Agreement and further may assign, or sell
participations in, all or any part of the Loans, the Revolving Loan Commitment
or any other interest herein to an Affiliate or to another Person. In the case
of an assignment authorized under this subsection 9.1, the assignee shall have,
to the extent of such assignment, the same rights, benefits and obligations as
it would if it were a Lender hereunder. Lender shall be relieved of its
obligations hereunder with respect to the Revolving Loan Commitment or assigned
portion thereof. Borrowers hereby acknowledge and agree that any assignment will
give rise to a direct obligation of Borrowers to the assignee and that the
assignee shall be considered to be a "Lender". Lender may furnish any
information concerning Borrowers and their Subsidiaries in its possession from
time to time to assignees and participants (including prospective assignees and
participants).

         9.2 Set Off. In addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, upon the
occurrence of any Event of Default, Lender, each assignee of Lender's interest,
and each participant is hereby authorized by Borrowers at any time or from time
to time, without notice to Borrowers or to any other Person, any such notice
being hereby expressly waived, to set off and to appropriate and to apply any
and all balances held by it at any of its offices for the account of a Borrower
or any of its Subsidiaries (regardless of whether such balances are then due to
a Borrower or its Subsidiaries) and any other property at any time held or owing
by that Lender or assignee to or for the credit or for the account of a Borrower
against and on account of any of the Obligations then outstanding; provided,
that no participant shall exercise such right without the prior written consent
of Heller.

         Each Borrower hereby agrees, to the fullest extent permitted by law,
that any Lender, assignee or participant may exercise its right of setoff with
respect to amounts in excess of its pro


                                       46

<PAGE>   54



rata share of the Obligations (or, in the case of a participant, in excess of
its pro rata participation interest in the Obligations) and that such Lender,
assignee or participant, as the case may be, shall be deemed to have purchased
for cash in the amount of such excess, participations in each other Lender's or
holder's share of the Obligations.

         9.3 Expenses and Attorneys' Fees. Whether or not the transactions
contemplated hereby shall be consummated, Borrowers agree to promptly pay all
fees, costs and expenses incurred by Lender in connection with any matters
contemplated by or arising out of this Agreement or the other Loan Documents
including the following, and all such fees, costs and expenses shall be part of
the Obligations, payable on demand and secured by the Collateral: (a) fees,
costs and expenses (including attorneys' fees, allocated costs of internal
counsel, per diem charges of Lender's internal auditors and fees of
environmental consultants, accountants and other professionals retained by
Lender) incurred in connection with the examination, review, due diligence
investigation, documentation and closing of the financing arrangements evidenced
by the Loan Documents; (b) fees, costs and expenses (including attorneys' fees,
allocated costs of internal counsel, per diem charges of Lender's internal
auditors and fees of environmental consultants, accountants and other
professionals retained by Lender) incurred in connection with the review,
negotiation, preparation, documentation, execution and administration of the
Loan Documents, the Loans, and any amendments, waivers, consents, forbearances
and other modifications relating thereto or any subordination or intercreditor
agreements; (c) fees, costs and expenses incurred in creating, perfecting and
maintaining perfection of Liens in favor of Lender; (d) fees, costs and expenses
incurred in connection with forwarding to Borrowers the proceeds of Loans
including Lender's standard wire transfer fee; (e) fees, costs, expenses and
bank charges, including bank charges for returned checks, incurred by Lender in
establishing, maintaining and handling lock box accounts, blocked accounts or
other accounts for collection of the Collateral; (f) fees, costs, expenses
(including attorneys' fees, allocated costs of internal counsel, per diem
charges of Lender's internal auditors and fees of environmental consultants,
accountants and other professionals retained by Lender) and costs of settlement
incurred in collecting upon or enforcing rights against the Collateral or
incurred in any action to enforce this Agreement or the other Loan Documents or
to collect any payments due from Borrowers under this Agreement or any other
Loan Document or incurred in connection with any refinancing or restructuring of
the credit arrangements provided under this Agreement, whether in the nature of
a "workout" or in connection with any insolvency or bankruptcy proceedings or
otherwise.

         9.4 Indemnity. In addition to the payment of expenses pursuant to
subsection 9.3, whether or not the transactions contemplated hereby shall be
consummated, each Borrower agrees to indemnify, pay and hold Lender and the
officers, directors, employees, agents, consultants, auditors, persons engaged
by Lender to evaluate or monitor the Collateral, affiliates and attorneys of
Lender and such holders (collectively called the "Indemnitees") harmless from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever (including the fees and disbursements of counsel for such
Indemnitees in connection with any investigative, administrative or judicial
proceeding commenced or threatened, whether or not such Indemnitee shall be
designated a party thereto) that may be imposed on, incurred by, or asserted
against that Indemnitee, in any manner


                                       47

relating to or arising out of this Agreement or the other Loan Documents, the
consummation of the transactions contemplated by this Agreement, the statements
contained in the commitment letters, if any, delivered by Lender, Lender's
agreement to make the Loans hereunder, the use or intended use of the proceeds
of any of the Loans or the exercise of any right or remedy hereunder or under
the other Loan Documents (the "Indemnified Liabilities"); provided that
Borrowers shall have no obligation to an Indemnitee hereunder with respect to
Indemnified Liabilities arising from the gross negligence or willful misconduct
of that Indemnitee as determined by a court of competent jurisdiction.

         9.5 Amendments and Waivers. No amendment, modification, termination or
waiver of any provision of this Agreement or of the other Loan Documents, or
consent to any departure by Borrowers therefrom, shall be effective unless the
same shall be in writing and signed by Lender and Borrowers. Each amendment,
modification, termination or waiver shall be effective only in the specific
instance and for the specific purpose for which it was given.

by written notice to the serving party, given in accordance with this subsection
9.6.

         9.7 Survival of Warranties and Certain Agreements. All agreements,
representations and warranties made herein shall survive the execution and
delivery of this Agreement and the making of the Loans hereunder.
Notwithstanding anything in this Agreement or implied by law to the contrary,
the agreements of Borrowers set forth in subsections 9.3 and 9.4 shall survive
the payment of the Loans and the termination of this Agreement.

         9.8 Indulgence Not Waiver. No failure or delay on the part of Lender in
the exercise of any power, right or privilege shall impair such power, right or
privilege or be construed to be a waiver of any default or acquiescence therein,

preclude other or further exercise thereof or of any other right, power or
privilege.

         9.9 Marshaling; Payments Set Aside. Lender shall not be under any
obligation to marshal any assets in favor of any Borrower or any other party or
against or in payment of any or all of the Obligations. To the extent that any
Borrower makes a payment or payments to Lender or Lender enforces its security
interests or exercise its rights of setoff, and such payment or payments or the
proceeds of such enforcement or setoff or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then to the
extent of such recovery, the Obligations or part thereof originally intended to
be satisfied, and all Liens, rights and remedies therefor, shall be revived and
continued in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.

         9.10 Entire Agreement. This Agreement and the other Loan Documents
referred to herein embody the final, entire agreement among the parties hereto

condition exists.

         9.12 Severability. The invalidity, illegality or unenforceability in
any jurisdiction of any provision in or obligation under this Agreement or the

jurisdiction.

         9.16     No Fiduciary Relationship; Limitation of Liabilities.

                  (A) No provision in this Agreement or in any of the other Loan
Documents and no course of dealing between the parties shall be deemed to create
any fiduciary duty by Lender to a Borrower.

                  (B) Neither Lender, nor any affiliate, officer, director,
shareholder, employee, attorney, or agent of Lender shall have any liability
with respect to, and each Borrower hereby waives, releases, and agrees not to
sue any of them upon, any claim for any special, indirect, incidental, or
consequential damages suffered or incurred by a Borrower in connection with,
arising out of, or in any way related to, this Agreement or any of the other

FORUM NON CONVENIENS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR
THE OBLIGATIONS.

         9.18 WAIVER OF JURY TRIAL. EACH BORROWER AND LENDER HEREBY WAIVE THEIR
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS. EACH BORROWER AND
LENDER ACKNOWLEDGE THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A
BUSINESS RELATIONSHIP, THAT EACH HAS ALREADY RELIED ON THE WAIVER IN ENTERING

Agreement shall become effective upon the execution of a counterpart hereof by
each of the parties hereto. Delivery of an executed counterpart of a signature
page to this Agreement, any amendments, waivers, consents or supplements, or to

manually executed counterpart thereof.

         9.21 No Duty. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by Lender shall have the right to

duty of loyalty, duty of care, or other duty or obligation of any type or nature
whatsoever to any Borrower or any of any Borrower's shareholders or any other
Person.

confidential information of this nature and in accordance with safe and sound
business practices and in any event may make disclosure to such of its
respective Affiliates, officers, directors, employees, agents and
representatives as need to know such information in connection with the Loans.
If any Lender is otherwise a creditor of a Borrower, such Lender may use the
information in connection with its other credits. Lender may also make
disclosure reasonably required by a bona fide offeree or assignee (or
participation), or as required or requested by any governmental authority or
representative thereof, or pursuant to legal process, or to its accountants,
lawyers and other advisors, and shall require any such offeree or assignee (or
participant) to agree (and require any of its offerees, assignees or
participants to agree) to comply with this Section 9.22. In no event shall
Lender be obligated or required to return any materials furnished by a Borrower;
provided, however, each offeree shall be required to agree that if it does not
become an assignee (or participant) it shall return all materials furnished to
it by a Borrower in connection herewith.

         9.23 Adequate Disclosure. Any information or matter disclosed on a
given Schedule to this Agreement shall be deemed to be disclosed on all
