         SECTION 2.1. TERMS.

                  (a) The maximum aggregate principal amount of credit extended

credit, and shall include sums advanced and other credit extended by Lender to

"Revolving Credit Loan") up to the Maximum Loan Amount depending upon the
availability in the Borrowing Base, the requests of Borrower pursuant to the
terms and conditions of Section 2.2 below, and on such other basis as Lender 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 extension of credit to or for the benefit of
Borrower, and shall be due and payable in full upon the expiration of the Term.

payable monthly in arrears on the first Business Day of each month, at a rate
per annum (on the basis of the actual number of days elapsed over a year of 360
days) equal to the Base Rate, provided that after the occurrence and during the
continuance of an Event of Default such rate shall be equal to the Default Rate.
Each Revolving Credit Loan, advance and other extension of credit shall be
deemed evidenced by the Note, which is deemed incorporated by reference herein
and made a part hereof.

                  (d) Subject to the terms and conditions of this Agreement,
advances under the Loan shall be made against the sum of (i) a borrowing base
(the "A/R Standard Borrowing Base") equal to eighty-five percent (85%) of
Qualified Accounts due and owing from any Medicaid/Medicare, Insurer or other
Account Debtor plus (ii) a borrowing base (the "A/R Term Borrowing Base" and
collectively with the A/R Standard Borrowing Base, the "Borrowing Base") equal
to the lesser of (A) fifty percent (50%) of the A/R Standard Borrowing Base, or
(B) the difference of (x) the product of three (3) times the sum of (aa)
Borrower's most recent six months' trailing EBITDA plus (bb) Borrower's
pro-forma six months trailing EBITDA contribution from acquisitions(1) minus (y)

calculations shall be confirmed by Lender's audit.

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 two (2) Business Days 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 of any amount
required to be paid under this Agreement, whether as interest or for any other
Obligation, shall be deemed irrevocably to be a request for a Revolving Credit
Loan on the day following the due date in the amount required to pay such
interest or other Obligation if such was not paid by borrower on the due date.

                  (b) Borrower hereby irrevocably authorizes Lender to disburse
the proceeds of each Revolving Credit Loan requested, or deemed to be requested,
as follows: (i) the proceeds of each Revolving Credit Loan requested under
subsection 2.2(a)(i) shall be disbursed by Lender by wire transfer to such bank
account as may be agreed upon by Borrower or 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.

----------

(1) An acquisition's contribution, set forth in (B) above, shall be calculated
after the first month of operations following the closing of any such
acquisition as follows: the sum of (x) actual EBITDA for the first month after
the applicable acquisition and (y) the actual EBITDA results for the prior five
months under the previous owner. After the second month of operations, actual
EBITDA for the two months shall be added to the last four months of actual
EBITDA results under the prior owner. This calculation shall continue until

Collateral.

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 accounting rendered by Lender shall 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 a lockbox account (the "Lockbox") with Bank of
America, N.A. (or its successor) (the "Lockbox Bank"), subject to the provisions
of this Agreement, and shall execute with the Lockbox Bank a Lockbox Agreement
in the form attached as Exhibit B, and such other 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 (in accordance with Section
2.2(d)) 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 Lender will suffer immediate and irreparable injury and
have no adequate remedy at law, if Borrower, through its acts or omissions,
causes or permits Account Debtors to pay other than to the Lockbox Account, or
if Borrower fails to immediately deposit collections of Accounts or proceeds of
other Collateral in the Lockbox Account as herein required. Upon Borrower's
failure to comply with the terms of this Section 2.3, Lender will be entitled,
in addition to exercising any other rights and remedies available to it, to
assess a non-compliance fee which shall operate to increase the Base Rate by two
percent (2%) per



                                       10
<PAGE>   11

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 two (2) 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, upon written request by Borrower to
Lender, to Borrower at any time or times for so long as no Event of Default
exists.

         SECTION 2.4. FEES.

                  (a) Borrower shall unconditionally pay to Lender a commitment
fee equal to one hundred thousand dollars ($100,000.00), which commitment fee
shall be payable in full at Closing.

                  (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 four one hundredths of one percent (.04%) of the average amount by which the
Maximum Loan Amount exceeds the average amount of the outstanding principal
balance of the Revolving Credit Loans during the preceding month. The Usage Fee
shall be payable monthly in arrears on the first Business Day of each successive
calendar month.

                  (c) For so long as the Loan is available to Borrower, Borrower
unconditionally shall pay to Lender a monthly loan management fee (the "Loan
Management Fee") equal to three one hundredths of one percent (0.03%) of the
average amount of the outstanding principal balance of the Revolving Credit
Loans during the preceding month. The Loan Management Fee shall be payable
monthly in arrears on the first day of each successive calendar month.

                  (d) Borrower shall pay to Lender all out-of-pocket audit and
appraisal fees in connection with audits and appraisals of Borrower's books and
records and such other matters as Lender shall deem appropriate, which shall be
due and payable on the first Business Day of the month following the date of
issuance by Lender of a request for payment thereof to Borrower; provided,
however, that (i) absent the occurrence of an Event of Default and (ii)
exclusive of audit and appraisal fees and expenses related to acquisitions, the
other audit and appraisal fees shall be capped at $20,000.00 in any calendar
year.

                  (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.



                                       11
<PAGE>   12

         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 or Lender of any payments on or proceeds from any of
the Collateral, to the extent of such proceeds, (ii) the occurrence of an Event
of Default if 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 of this Agreement; 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
if the Loan and the maturity of the Obligations are accelerated, or (iii) the
termination of this Agreement pursuant to Section 2.8. Except to the extent
otherwise set forth in this Agreement, all payments of principal and of interest
on the Loan, all other charges and any other obligations of Borrower under this
Agreement, shall be made to Lender to the Concentration Account, in immediately
available funds.

         SECTION 2.6. USE OF PROCEEDS. The proceeds of Lender's advances under
the Loan shall be used solely for working capital, acquisitions (as permitted by
this Agreement) and general corporate purposes and to pay off the existing term
loan from Lender.

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



                                       12
<PAGE>   13

annum equal to the interest rate under the Note had at all times been in effect,
and (ii) 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 shall be
renewed for one-year periods thereafter upon the mutual written agreement of the
parties.

                  (b) Notwithstanding anything herein to the contrary, Lender
may terminate this Agreement upon fifteen (15) days written notice or after the
occurrence of an Event of Default and the expiration of any applicable cure
period.

                  (c) Upon at least thirty (30) days prior written notice to
Lender, Borrower may terminate this Agreement prior to the third annual
anniversary of the Closing Date, provided that, at the effective date of such
termination, Borrower shall pay the Termination Fee to Lender (in addition to
the then outstanding principal, accrued interest and other Obligations owing
under the terms of this Agreement and any other Loan Documents) as yield
maintenance for the loss of bargain and not as a penalty; provided, however, if
and only if Borrower terminates this Agreement and indefeasibly satisfies all
Obligations to Lender as a result of the initial public offering of Borrower
providing for net proceeds to the Borrower of no less than $20,000,000.00, the
Termination Fee shall be equal to the following: (i) the Termination Fee if the
date of notice of a termination is on or before the first anniversary of the
Closing Date shall be equal to one percent (1%) of the Maximum Loan Amount and
(ii) the Termination Fee if the date of notice of a termination is after the
first anniversary of the Closing Date and on or before the third anniversary of
the Closing Date shall be equal to one half of one percent (0.5%) of the Maximum
Loan Amount.

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



                                       13
<PAGE>   14

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.

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

                  (c) In addition, prior to Closing, at Borrower's expense,
Borrower shall obtain and deliver to Lender 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 currently intends to do business for which
qualification is required.

         SECTION 3.6. POWER OF ATTORNEY. Each of the officers of Lender is
hereby irrevocably made, constituted and appointed the true and lawful attorney
for Borrower (without requiring any of them to act as such) with full power of
substitution to do the following: (i) 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;
(ii) execute in the name of Borrower any financing statements, schedules,
assignments, instruments, documents, and statements that Borrower is obligated
to give Lender hereunder, and (iii) upon and during .the continuance of an Event
of Default 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.

                         REPRESENTATIONS AND WARRANTIES

         Each entity comprising Borrower represents and warrants to Lender, and
shall be deemed to represent and warrant on each day on which any Obligations
shall be outstanding hereunder, that:

         SECTION 4.1. SUBSIDIARIES. Except as set forth in Schedule 4.1.
Borrower has no subsidiaries.

         SECTION 4.2. ORGANIZATION AND GOOD STANDING. Except as set forth in
Schedule 4.2, Borrower is a corporation duly organized, validly existing, and in
good standing under the laws of its state of formation, 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 transaction of all of its business.

         SECTION 4.3. AUTHORITY. Borrower has full corporate power and authority
to enter 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 under the Loan Documents.

         SECTION 4.4. BINDING AGREEMENT. This Agreement and all other Loan
Documents constitute, and the Note, when issued and delivered pursuant to this
Agreement for value 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 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. The execution and delivery by Borrower of
this Agreement and the other Loan Documents do not, and the performance of its
obligations under the Loan Documents will not, violate, conflict with,
constitute a default under, or result in the creation of a



                                       18
<PAGE>   19

lien or encumbrance upon the property of Borrower (other than for the benefit of

bylaws, (ii) any provision of any law, rule, or regulation applicable to
Borrower, or (iii) any of the following: (A) any indenture or other agreement or
instrument to which Borrower is a party or by which Borrower or its property is
bound; or (B) any judgment, order or decree of any court, arbitration tribunal,
or Governmental Authority having jurisdiction over Borrower which is applicable
to Borrower.

Borrower as of December 31, 1999 audited by Ernst & Young and the unaudited
financial statements of Borrower as of March 31, 2000, certified by the chief

owing to Borrower and is not contingent in any respect or for any reason;

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

for any task in connection with the enforcement, protection or preservation of
any right or claim of Lender and the collection of any amounts due under this
Loan Documents), Borrower further agrees that its Obligations under the Loan
Documents include reasonable charges for such work commensurate with the fees
that would otherwise be charged by outside legal counsel selected by Lender for
the work performed.

                  (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 under this Agreement and
the termination of this Agreement.

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

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

         SECTION 9.5. SEVERABILITY. If any term, covenant or condition of this
Agreement, or the application of such term, covenant or condition to any party
or 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
application of such term, covenant, or condition to parties or circumstances
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term, covenant or condition shall be valid and
enforced to the fullest extent permitted by law. Upon determination that any
such term is invalid, illegal or unenforceable, Lender may, but is not obligated
to, advance funds to Borrower under this Agreement until the parties to this
Agreement shall amend this Agreement so as to effect the original intent of the
parties as closely as possible in a valid and enforceable manner.

         SECTION 9.6. SUCCESSORS AND ASSIGN. 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 under this Agreement without the prior written consent of Lender,
which may be withheld in its sole discretion. Lender may sell, assign, transfer,
or participate any or all of its rights or obligations under this Agreement
without notice to or consent of Borrower.

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

         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 with this
Agreement shall be considered to have been relied upon by Lender and shall
survive the making by Lender of the Loans contemplated by this Agreement 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. For and in consideration of the Loan,
Borrower, voluntarily, knowingly, unconditionally, and irrevocably, with
specific and express intent, for and on behalf of itself and its agents,
attorneys, heirs, successors, and assigns (collectively the "Releasing Parties")
does hereby fully and completely release, acquit and forever discharge Lender,
and its successors, assigns, heirs, affiliates, subsidiaries, parent companies,
principals, directors, officers, employees, shareholders and agents (hereinafter
called the "Lender Parties"); and any other person, firm, business, corporation,
insurer, or association which may be



                                       39
<PAGE>   40

responsible or liable for the acts or omissions of the Lender Parties, or who
may be liable for the injury or damage resulting therefrom (collectively the
"Released Parties"), of and from any and all actions, causes of action, suits,
debts, disputes, damages, claims, obligations, liabilities, costs, expenses and
demands of any kind whatsoever, at law or in equity, whether matured or
unmatured, liquidated or unliquidated, vested or contingent, choate or inchoate,
known or unknown that the Releasing Parties (or any of them) now have (whether
directly or indirectly) against the Released Parties or any of them. The
Borrower acknowledges that the foregoing release is a material inducement to
Lender's decision to extend to Borrower the financial accommodations hereunder
and has been relied upon by Lender in agreeing to make the Loan.

         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 under
this Agreement 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 sole
discretion, shall have the right at any time, and from time to time, without
prior notice to Borrower if Borrower fails to do so, to: (i) after notice to
Borrower and Borrower's refusal to perform, pay for the performance of any of
Borrower's material obligations under this Agreement; (ii) 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
(iii) pay for the maintenance and preservation of any of the Collateral.
Expenses and advances shall be added to the Loan, until reimbursed to Lender and
shall be secured by the Collateral. Any such payments and advances by Lender
shall not be construed as a waiver by Lender of an Event of Default.

         SECTION 9.15. INFORMATION TO PARTICIPANTS. Lender may divulge to any
participant it may obtain in the Loan, or any portion of the Loan, all
information, and furnish to such



                                       40
<PAGE>   41

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 under this Agreement, or from the breach of any of the
representations or warranties contained in Article IV of this Agreement. In
addition, 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. LENDER APPROVALS. Unless expressly provided herein to the
contrary, any approval, consent, waiver or satisfaction of Lender with respect
to any matter that is the subject of this Agreement or the other Loan Documents
may be granted or withheld by Lender in its sole and absolute discretion.

         SECTION 9.18. 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 ACTION ARISING OUT OF THIS AGREEMENT OR THE NOTE IS
COMMENCED BY LENDER IN THE STATE COURTS OF THE STATE OF MARYLAND OR IN THE U.S.
DISTRICT COURT FOR THE DISTRICT OF MARYLAND, BORROWER HEREBY CONSENTS TO THE
JURISDICTION OF ANY SUCH COURT IN ANY SUCH ACTION AND TO THE LAYING OF VENUE IN
THE STATE OF MARYLAND. ANY PROCESS IN ANY SUCH ACTION SHALL BE DULY SERVED IF
MAILED BY REGISTERED MAIL, POSTAGE PREPAID, TO BORROWER AT ITS ADDRESS DESCRIBED
IN SECTION 9.4 HEREOF.

         SECTION 9.19. WAIVER OF TRIAL BY JURY. BORROWER HEREBY (A) COVENANTS
AND AGREES NOT TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY A JURY,
AND (B) WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH
RIGHT SHALL NOW OR HEREAFTER EXIST. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS
SEPARATELY GIVEN, KNOWINGLY AND VOLUNTARILY, BY BORROWER, AND THIS WAIVER IS
INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE
RIGHT TO A JURY TRIAL WOULD OTHERWISE ACCRUE. LENDER IS HEREBY AUTHORIZED AND
REQUESTED TO SUBMIT THIS AGREEMENT TO ANY COURT HAVING JURISDICTION OVER THE
SUBJECT MATTER AND THE PARTIES TO THIS AGREEMENT, SO AS TO SERVE AS CONCLUSIVE
EVIDENCE OF BORROWER'S WAIVER OF THE RIGHT TO JURY TRIAL. FURTHER, BORROWER
HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF LENDER (INCLUDING LENDER'S
COUNSEL)



                                       41
<PAGE>   42

HAS REPRESENTED, EXPRESSLY OR OTHERWISE, TO BORROWER THAT LENDER WILL NOT SEEK
TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION.

         SECTION 9.20. 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 REASONABLE ATTORNEYS' FEES ALL AS
ENUMERATED UNDER THIS AGREEMENT, 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 OR DIFFERENT JURISDICTIONS, AS
OFTEN AS LENDER SHALL DEEM NECESSARY, CONVENIENT, OR PROPER.

         SECTION 9.21. PRIORITY; OBLIGATIONS COMBINED. Borrower and Lender agree
that the first priority status of Lender's lien on and security interest in the
Collateral shall continue and date back to the date on which the Borrower's
original grant of such lien and security interest was made (i.e., March 5,
1998). The Obligations under the Original Agreement and this Agreement are
hereby combined and shall constitute joint and several obligations of each and
every Borrower.
