                                      LOAN

SECTION 2.1. TERMS.

         (a) The maximum aggregate principal amount of credit extended by Lender
to Borrower hereunder (the "Loan") that may be outstanding at any time is Seven
Million and No/100 ($7,000,000.00) (the "Maximum Loan Amount"). Notwithstanding
the foregoing, or anything else in this Agreement to the contrary, however, the
total of the aggregate outstanding principal amount of the Loan made under this
Agreement and the aggregate outstanding principal amount of the Loan under the
New LOC II Agreement shall not exceed Twelve Million and No/100
($12,000,000.00).

         (b) The Loan shall be in the nature of a revolving line of credit, and
shall include sums advanced and other credit extended by Lender to or for the
benefit of the Borrower from time to time under this Article 2 (each a
"Revolving Credit Loan"), limited at all times to the least of: (i) the Maximum
Loan Amount; (ii) the availability in the Borrowing Base; or (iii) the
difference between $12,000,000.00 and the outstanding Loan owing pursuant to the
New LOC II Agreement (as defined therein). Depending on the requests of Borrower
pursuant to the terms and conditions of Sections 2.1(e) and 2.2 below, the
outstanding principal balance of the Loan may fluctuate from time to time, to be
reduced by repayments made by Borrower (which may be made without penalty or
premium), and to 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 ability within the Borrowing
Base for advances or extensions of credit shall be made by Lender in its
reasonable discretion and is final and binding upon Borrower.


                                      -7-
<PAGE>   9
         (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 (including without limitation Borrower's obligations with respect to
Letters of Credit), in the form of Exhibit A to this Agreement (the "Note"),
dated the date hereof, payable to the order of Lender in accordance with the
terms thereof. The Note (and the principal balance of the Loan outstanding from
time to time thereunder, but not including the portion of the Loan owing for
undrawn Letters of Credit) shall bear interest from the date thereof 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 an
occurrence or 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 by reference herein and made a part hereof.

         (d) As used herein, the term "Borrowing Base" shall mean that amount
equal, at any applicable time, to eighty-five percent (85%) of Qualified
Accounts due and owing from any Medicaid/Medicare Account Debtor, Insurer or
other Account Debtor. Notwithstanding any other provision of this Agreement,
advances under the Loan shall not be made in an amount that would cause the
total amount outstanding under the Loan (after taking into account a proposed
advance) to exceed the amount of the Borrowing Base.

         (e) Borrower may request from time to time that Lender obtain from
Issuing Bank irrevocable standby letters of credit (collectively, the "Letters
of Credit") issued on behalf of Borrower for the benefit of third parties
identified by Borrower, provided that: (i) the aggregate amount that
beneficiaries of outstanding Letters of Credit may draw at any time may not
exceed the amount equal to $2,500,000.00 less the aggregate face amount of all
Letters of Credit outstanding pursuant to the New LOC II Agreement; and (ii)
when a Letter of Credit is issued, the maximum amount that can be drawn on that
Letter of Credit by the beneficiary thereof shall be deemed an advance under
this Agreement for purposes of determining Borrower's borrowing capacity under
the Loan. Such advances shall be deemed Revolving Credit Loans and therefore
part of the Loan owing by Borrower hereunder, but shall be deemed to be repaid
as the amounts that can be drawn under Letters of Credit are reduced from time
to time in accordance with the terms and conditions thereof. In the event of any
draw under a Letter of Credit: (i) Borrower shall immediately thereafter pay to
Lender an amount equal to all amounts that Lender has paid to, or owes, Issuing
Bank in relation to that Letter of Credit; and (ii) the portion of the Loan
comprised of Borrower's obligations with respect to the Letter of Credit drawn
upon shall thereafter bear interest at the applicable rate for the remainder of
the Loan (not including obligations related to other Letters of Credit). Payment
and performance of all obligations and liabilities of Borrower to Lender arising
in connection with the Letters of Credit, including but not limited to all
obligations and liabilities of Borrower to Lender under the fee and
reimbursement agreement (in a form acceptable to Lender in its sole discretion)
that shall be entered into by Borrower and Lender with respect to each Letter of
Credit, shall be secured by the liens and security interests in the Collateral
granted to Lender under this Agreement. Notwithstanding any of the foregoing,
Lender's failure, for any reason, to obtain a Letter of Credit on behalf of
Borrower following a request by Borrower shall not constitute a default by
Lender under this Agreement.

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 shall be
deemed to be made, in the following manner: (i) Borrower may give 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 2:00 p.m.
Eastern time one (1) Business Day prior to the proposed borrowing date;
provided, however, that no such request may be made at a time when there exists
an Event of Default; and (ii) the becoming due (after the expiration of the
applicable grace period, if any) 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 due date in the
amount required to pay such interest or other Obligation.

         (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
subsection 2.2(a)(i) shall be disbursed by Lender by wire transfer to such bank
account as may be agreed upon by Borrower and Lender from time to time or
elsewhere if pursuant to written direction from Borrower; and (ii) the proceeds
of each Revolving Credit Loan requested under subsection 2.2(a)(ii) shall be
disbursed by Lender by way of direct payment of the relevant interest or other
Obligation.

         (c) All Revolving Credit Loans, advances and other extensions of credit
to or for the benefit of Borrower shall constitute the Obligation of Borrower,
and shall be secured by Lender's lien upon all of the Collateral of the
Borrower.

         (d) Lender shall enter all Revolving Credit Loans as debits to a loan
account in the name of Borrower and shall also record in said loan account 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 account rendered by Lender shall, absent manifest error, be deemed
final, binding and conclusive upon Borrower 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 therein.

 SECTION 2.3. COLLECTIONS, DISBURSEMENTS, BORROWING AVAILABILITY, AND LOCKBOX
ACCOUNT. Borrower shall maintain one or more lockbox accounts (collectively, the
"Lockbox") with Bank One Arizona, N.A. (the "Lockbox Bank"), subject to the
provisions of this Agreement, and shall execute with the Lockbox Bank a Lockbox
Agreement in the form acceptable to Lender, and such other 


                                      -9-
<PAGE>   11
agreements related thereto as Lender may require. Borrower shall ensure that all
collections of Accounts are paid directly from Account Debtors into the Lockbox,
and that all funds paid into the Lockbox are immediately transferred into a
depository account maintained by Lender at Bank One Arizona, N.A. or U.S. Bank
N.A., as determined by Lender in its sole discretion and communicated to
Borrower (the "Concentration Account"). 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, with 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
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. Borrower acknowledges and agrees that its compliance with the terms of
this Section 2.3 is essential, and that upon its failure to comply with any such
terms Lender shall be entitled 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. Lender shall be entitled to assess such fee whether or
not an Event of Default is declared or otherwise occurs. 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 five (5) 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 exists.

 SECTION 2.4.  FEES.

         (a) Upon execution of this Agreement, Borrower shall unconditionally
pay to Lender a commitment fee equal to Ten Thousand and No/100 Dollars
($10,000.00) (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 one twelfth (1/12th) of one and one-quarter percent (1.25%) 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 day of
each successive calendar month.

         (c) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a quarterly loan management fee (the "Loan
Management Fee") equal to Three Thousand Seven Hundred Fifty and No/100 Dollars
($3,750.00) per quarter within the Term. The Loan Management Fee shall be
payable quarterly in advance on the first day of each February, May, August and
November while this Agreement remains in effect.

         (d) Borrower shall pay to Lender all reasonable audit and appraisal
fees in connection with audits and appraisals of Borrower's books and records on
not more than a quarterly basis while no Event of Default exists and is
continuing, which shall be due and payable on the first Business 


                                      -10-
<PAGE>   12
Day of the month following the date of issuance by Lender of a request for
payment thereof to Borrower; provided, however, that (i) absent an Event of
Default the payment by Borrower of the quarterly Loan Management Fee shall
satisfy its payment obligations under this Section 2.4(d) for the applicable
quarter, and (ii) following the occurrence or during the continuation of an
Event of Default the hourly rates of the professionals selected by Lender to
perform the audits and appraisals shall be reasonable in relation to the scope
of the services performed.

         (e) Borrower shall pay to Lender, on demand, any and all 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.

         (f) Borrower shall pay to Lender, on demand, any and all fees, costs or
expenses which Lender pays to Issuing Bank arising out of or in connection with
any Letter of Credit issued on behalf of Borrower. In addition, on the date that
any Letter of Credit is issued or renewed by Issuing Bank, Borrower shall pay to
Lender a fee equal to four percent (4%) of the face amount of the Letter of
Credit issued or renewed.

SECTION 2.5. PAYMENTS. Principal payable on account of Revolving Credit Loans
shall be payable by Borrower to Lender immediately upon the earliest of (i) the
receipt by Borrower of any proceeds of any of the Collateral, to the extent of
such proceeds, (ii) any draw under a Letter of Credit, to the extent provided in
Section 2.1(e) hereof, (iii) the occurrence of an Event of Default in
consequence of which the Loan and the maturity of the payment of the Obligations
are accelerated, or (iv) the termination of this Agreement pursuant to Section
2.8 hereof; provided, however, that if any advance made by Lender in excess of
the Borrowing Base shall exist at any time, Borrower shall, immediately upon
demand, repay such overadvance. Interest accrued on the Revolving Credit Loans
shall be due on the earliest of (i) the first Business Day of each month (for
the immediately preceding month), computed on the last calendar day of the
preceding month, (ii) the occurrence of an Event of Default in consequence of
which the Loan and the maturity of the payment of the Obligations are
accelerated, or (iii) the termination of this Agreement pursuant to Section 2.8
hereof. 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 hereunder, shall be made to Lender to the Concentration
Account, in immediately available funds.

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 hereby 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 


                                      -11-
<PAGE>   13
Agreement 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 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 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 (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 herein, to the Highest Lawful
Rate, but any subsequent reductions in the Base 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. If the total amount of interest paid
or accrued pursuant to this Agreement under the foregoing provisions is less
than the total mount of interest that would have accrued if a varying rate per
annum equal to the interest rate under the Note had been in effect, then
Borrower agrees to pay to Lender an amount equal to the difference between (a)
the lesser of (i) the amount of interest that would have accrued if the Highest
Lawful Rate had at all times been in effect, or (ii) 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, and (b) the amount of interest accrued
in accordance with the other provisions of this Agreement.

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 three (3) years from the Closing Date, unless terminated as
provided in this Section 2.8 (the "Term"), and this Agreement may be renewed for
one-year periods thereafter upon the mutual written agreement of the parties.

         (b) Upon at least thirty (30) days prior written notice to Borrower,
Lender may terminate this Agreement as of the end of the Term. In all events,
however, 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 before the
third annual anniversary of the Closing Date, provided that, at the effective
date of such termination, 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 liquidated damages for
the loss of bargain and not as a penalty, an amount equal to (i) two percent
(2%) of the Maximum Loan Amount if the effective date of such termination by
Borrower is on or before the first annual anniversary of the Closing Date, (ii)
one percent (1%) of the Maximum Loan Amount if the effective date of such
termination by Borrower is after the first annual anniversary of the Closing
Date and before the 


                                      -12-
<PAGE>   14
second annual anniversary of the Closing Date, and (iii) one percent (1%) of the
Maximum Loan Amount if the effective date of such termination by Borrower is
after the second annual anniversary of the Closing Date and before the third
annual anniversary of the Closing Date.

         (d) All of the Obligations shall be immediately due and payable upon
the termination date of this Agreement (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.

         (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. Joint and Several Liability; Binding Obligations. Each entity
comprising Borrower and executing this Agreement on behalf of Borrower shall be
jointly and severally liable for all of the Obligations. In addition, each
entity comprising Borrower hereby acknowledges and agrees that all of the
representations, warranties, covenants, obligations, conditions, agreements and
other terms contained in this Agreement shall be applicable to and shall be
binding upon each individual entity comprising Borrower, and shall be binding
upon all such entities when taken together.

<PAGE>   16
In addition, and without in any way limiting the foregoing, the continuing first
priority lien on and security interest in, upon, and to the Collateral granted
by Borrower to Lender shall secure payment, performance and observance by New
LOC II Borrower of each covenant, condition, provision and agreement contained
in the New LOC II Agreement and related loan and security documents.

Notwithstanding anything in this Agreement to the contrary, the parties agree
that if (i) Lender has extended credit hereunder equal to the Maximum Loan
Amount, and (ii) thereafter Borrower receives an offer, term sheet or commitment
(for purposes of the Section, an "Offer") from any Person to provide permanent,
long term, short term or any other financing (for purposes of this Section,
"Additional Financing") with respect to Borrower, Borrower shall first forward
the Offer to the Lender, and the Lender shall have thirty (30) days after
receipt (the "Option Period") to agree to provide the Additional Financing in
place of such third party upon the terms and conditions set forth in the Offer
and to notify Borrower in writing of the Lender's acceptance of the Offer (the
"Acceptance Notice"). If Borrower has not received an Acceptance Notice within
the Option Period, then Borrower shall be free to consummate the transaction
described in the Offer with the third party providing the Offer (the
"Transaction"), provided that (a) any liens on Collateral granted to such third
party shall be generated solely and exclusively through the operation of one or
more nursing homes or other healthcare facilities not owned, operated or managed
by any of the entities comprising Borrower as of the Closing Date, and (b)
Lender shall obtain signed documentation from such third party financing source
confirming (in form and substance satisfactory to Lender, in its sole
discretion) that such third party has no security interest in any of the
Collateral generated at any nursing home or other healthcare facility owned,
operated or managed by any of the entities comprising Borrower as of the Closing
Date. If the Transaction is not consummated with such third party during the
longer of (i) the one hundred twenty (120) day period following the expiration
of the Option Period, and (ii) the period (if any) proposed in the Offer for
completion of the Transaction, then Borrower shall not be permitted to
consummate the Transaction without again complying with this Section. For
purposes of this Section only, the "Lender" shall mean and include either of
HCFP Funding, Inc., HCFP Funding II, Inc., HealthCare Financial Partners REIT, a
Maryland corporation, or any other parent company, subsidiary or Affiliate of
HCFP Funding, Inc. or the parent company or subsidiaries of any of such
entities.

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):

         (a) UCC-1 Financing statements pursuant to the Uniform Commercial Code
in effect in the jurisdictions in which Borrower operates, which Lender may file
in any State where any Collateral is or may be located and in any other
jurisdiction that Lender deems appropriate; provided that a carbon,
photographic, or other reproduction or other copy of this Agreement or of a
financing statement is sufficient as and may be filed in lieu of a financing
statement;

         (b) Any other agreements, documents, instruments, and writings deemed
necessary by Lender or as Lender may otherwise request from time to time in its
reasonable discretion to evidence, perfect, or protect Lender's liens and

<PAGE>   17
SECTION 3.3. COLLATERAL ADMINISTRATION.

         (a) All Collateral (except deposit accounts) will at all times be kept
by Borrower at its principal office(s) as set forth on Schedule 4.15 hereto and
shall not, without the prior written approval of Lender, be moved therefrom.

         (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 on the first Business Day following such occurrence (or
immediately upon Borrower's preparation of a monthly aging schedule if the
reason for ineligibility is that the Account has remained unpaid for longer than
the applicable period for Qualified Accounts), 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, 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 retains the right
at all times after the occurrence and during the continuance of an Event of
Default, subject to applicable law regarding Medicaid/Medicare Account Debtors,
to notify Account Debtors that Accounts have been assigned to Lender and to
collect Accounts directly in its own name and to charge the collection costs and
expenses, including attorneys' fees to Borrower.

SECTION 3.4. OTHER ACTIONS. In addition to the foregoing, Borrower (i) 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 hereof that the Lender has been granted a first
priority lien and security interest in, upon and to all Accounts applicable to
such Insurer, and hereby authorizes Lender to send any and all similar notices
to such Insurers by Lender, and (ii) shall 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 hereunder. At Lender's request,
Borrower shall also immediately deliver to Lender all items for which Lender
must receive possession to obtain a perfected security interest. Borrower shall,
on Lender's demand, deliver to Lender all notes, certificates, and documents 


                                      -16-
<PAGE>   18
of title, chattel paper, warehouse receipts, instruments, and any other similar
instruments constituting Collateral.

SECTION 3.5. SEARCHES. Prior to Closing, and thereafter (as and when requested
by Lender in its reasonable discretion), Borrower shall obtain and deliver to
Lender the following searches against Borrower (the results of which are to be
consistent with Borrower's representations and warranties under this Agreement),
all at its own 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;

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

         (c) Good standing certificates showing Borrower to be in good standing
in its state of formation and in each other state in which it is doing and
presently intends to do business for which qualification is required.

SECTION 3.6. POWER OF ATTORNEY. To the extent permitted by applicable bankruptcy
law, each of the officers of Lender is hereby, or, if required, upon application
to the bankruptcy court, may be, 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 hereunder; and (c) 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.

subsidiaries.

SECTION 4.2. ORGANIZATION AND GOOD STANDING. Borrower is a corporation duly
organized, validly existing, and in good standing under the laws of its state of
incorporation, is in good standing as a foreign corporation in each jurisdiction
in which the character of the properties owned or leased by it therein or the
nature of its business makes such qualification necessary, has the corporate
power and authority to own its assets and transact the business in which it is
engaged, and has obtained all certificates, licenses and qualifications required
under all laws, regulations, ordinances, or orders of public authorities
necessary for the ownership and operation of all of its properties and

into, execute, and deliver this Agreement and to perform its obligations
hereunder, to borrow the Loan, to execute and deliver the Note, and to incur and
perform the obligations provided for in the Loan Documents, all of which have
been duly authorized by all necessary corporate action. No consent or approval
of shareholders of, or lenders to, Borrower and no consent, approval, filing or
registration with any Governmental Authority is required as a condition to the
validity of the Loan Documents or the performance by Borrower of its obligations
thereunder.

SECTION 4.4. BINDING AGREEMENT. This Agreement and all other Loan Documents

received, will constitute, the valid and legally binding obligations of
Borrower, enforceable against Borrower in accordance with their respective
terms.

SECTION 4.5. LITIGATION. Except as disclosed in Schedule 4.5, there are no
actions, suits, proceedings or investigations pending or threatened against
Borrower before any court or arbitrator or before or by any Governmental
Authority which, in any one case or in the aggregate, if determined adversely to
the interests of the Borrower, could have a material adverse effect on the
business, properties, condition (financial or otherwise) or operations, present
or prospective, of Borrower, or upon its ability to perform its obligations
under the Loan Documents. Borrower is not in default with respect to any order
of any court, arbitrator, or Governmental Authority applicable to Borrower or
its properties.

SECTION 4.6. NO CONFLICTS. Except as disclosed in Schedule 4.6, the execution
and delivery by Borrower of this Agreement and the other Loan Documents do not,
and the performance of its obligations thereunder will not, violate, conflict
with, constitute a default under, or result in the creation of a lien or
encumbrance upon the property of Borrower under: (a) any provision of Borrower's
articles of incorporation or its bylaws, (b) any provision of any law, rule, or
regulation applicable to Borrower, or (c) any of the following: (i) any lease,
indenture or other agreement or instrument to which Borrower is a party or by

 SECTION 4.29. YEAR 2000 COMPLIANCE. Borrower will use its best efforts to
insure that all devices, systems, machinery, information technology, computer
software and hardware, and other date sensitive technology (jointly and

business, assets, liabilities, financial condition, business prospects and
results of operations. All inspections by representatives of Lender are for the

such outstanding stock, return any such capital, or pay any such management
fees, so long as doing so would not violate any of the other terms and
conditions of this Agreement.

other than (i) trade credit extended in the ordinary course of its business,
(ii) advances for business travel and similar temporary advances in the ordinary

permitted by this Agreement, Borrower will not enter into 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 hereunder. 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

patient occupancy rate at all facilities listed in Schedule 4.15 as of the
Closing Date.

SECTION 7.19. PROHIBITION ON AMENDMENTS TO ORGANIZATIONAL DOCUMENTS. No Borrower
will amend, modify, restate, supplement, or terminate its respective certificate
of incorporation or bylaws (or other organizational documents) in any manner
that would materially affect the validity and 


                                      -33-

law, any perishable Collateral which threatens to speedily decline in value or
which is sold on a recognized marked 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. At any sale or disposition of Collateral, Lender may (to

obligations of New LOC II Borrower under the New LOC II Agreement and related
loan and security documents.. All rights and remedies granted Lender hereunder

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
Loans, 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.

appraisal fees and all other out-of-pocket charges and expenses incurred by
Lender in connection with the negotiation, preparation, legal review and
execution of each of the Loan Documents. In addition, Borrower shall pay all
such fees associated with any amendments to the Loan Documents following
Closing.

         (b) 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 (b) shall
survive the payment of Borrower's indebtedness hereunder 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 hereto 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 


                                      -38-
<PAGE>   40
nature. No failure or delay on the part of any party in exercising any right,
power or remedy hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right, power or remedy preclude any other
or further exercise thereof or the exercise of any other right, power or remedy.
The remedies provided for herein are cumulative and are not exclusive of any
remedies that may be available to any party hereto at law, in equity or
otherwise.

circumstance shall be found by a court of competent jurisdiction to be, to any
extent, invalid or unenforceable, the remainder of this Agreement and the

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, the parties hereto shall amend
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable 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. Notwithstanding the
foregoing, Borrower may not assign any of its rights or delegate any of its
obligations hereunder 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 hereunder with ten calendar
days' notice to, but without requiring the 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.

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.

SECTION 9.9. SURVIVAL OF TERMS. All covenants, agreements, representations and
warranties made in this Agreement, any other Loan Document, and in any
certificates and other instruments delivered in connection therewith shall be
considered to have been relied upon by Lender and shall survive the making by
Lender of the Loans herein contemplated and the execution and delivery to Lender
of the Note, and shall continue in full force and effect until all liabilities
and obligations of Borrower to Lender are satisfied in full.

SECTION 9.10. RELEASE OF LENDER. Borrower releases Lender, its officers,
employees, and agents, of and from any claims for loss or damage resulting from
acts or conduct of any or all of them, unless caused by Lender's recklessness,
gross negligence, or willful misconduct.

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. 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 hereunder or
under any other Loan Document for the benefit of any third party donee,
creditor, or incidental beneficiary of Borrower. 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 reasonable
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 hereunder; (b) pay for the
performance of any of Borrower's obligations hereunder; (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. 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 thereof, 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.

 SECTION 9.16. INDEMNITY. Borrower hereby agrees to indemnify and hold harmless
Lender, its partners, officers, agents and employees (collectively,
"Indemnitee") from and against any liability, loss, cost, expense, claim,
damage, suit, action or proceeding ever suffered or incurred by Lender
(including reasonable attorneys' fees and expenses) arising from Borrower's
failure to observe, perform or discharge any of its covenants, obligations,
agreements or duties hereunder, or from the breach of any of the representations
or warranties contained in Article IV hereof. In addition, with the exception of
claims asserted in the motion for approval of debtor in possession financing,
Borrower shall defend Indemnitee against and save it harmless from all claims of
any Person with respect to the Collateral. 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. CHOICE OF LAW; CONSENT TO JURISDICTION. 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 COLLECTION ACTION ARISING OUT OF THIS AGREEMENT OR THE
NOTE IS COMMENCED BY LENDER IN THE STATE OF MARYLAND OR FEDERAL COURT LOCATED IN
THE STATE 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 


                                      -42-
<PAGE>   44
DULY SERVED IF MAILED BY REGISTERED MAIL, POSTAGE PREPAID, TO THE BORROWER AT
ITS ADDRESS DESCRIBED IN SECTION 9.4 HEREOF.

SECTION 9.18. 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 HERETO, 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 9.19. 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 OF 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. 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 


                                      -43-
<PAGE>   45
OR DIFFERENT JURISDICTIONS, AS OFTEN AS LENDER SHALL DEEM NECESSARY, CONVENIENT,
OR PROPER.
