                  LOAN AND SECURITY AGREEMENT, dated as of April 6, 2001,
between ATC FUNDING, LLC, a limited liability company organized under the laws
of the State of Delaware (together with its successors and assigns, the
"BORROWER"), and HFG HEALTHCO-4 LLC, a Delaware limited liability company
(together with its successors and assigns, the "LENDER"), agree as follows:

                  Certain terms that are capitalized and used throughout this
Agreement are defined in Exhibit I to this Agreement. References herein, and in
the Exhibits and Schedules hereto, to the "Agreement" refer to this Agreement,
as amended, restated, modified or supplemented from time to time in accordance
with its terms (this "AGREEMENT").

                  The Borrower (i) is a limited liability company owned by the
Providers, (ii) has acquired and will acquire receivables from the Providers by
purchase or contribution to the capital of the Borrower pursuant to the RPTA, as
determined from time to time by the Borrower and the Providers, and (iii) wishes
to borrow funds from the Lender on a continuing and revolving basis secured by
all of its assets, including the receivables acquired from the Providers.

                  The Lender is prepared to make a revolving loan secured by the
Borrower's assets, including such receivables on the terms and subject to the
conditions set forth herein.

                  Accordingly, the parties agree as follows:


                                   ARTICLE I.
               COMMITMENT; AMOUNTS AND TERMS OF THE REVOLVING LOAN

                  Section I.1. Revolving Advances. (a) The Lender agrees to lend
from time to time to the Borrower, subject to and upon the terms and conditions
herein set forth, on each Funding Date, such amounts as, in accordance with the
terms hereof, may be requested by the Borrower (each such borrowing, a
"REVOLVING ADVANCE" and the aggregate outstanding principal balance of all
Revolving Advances from time to time, the "REVOLVING Loan").

                  (b) Each Revolving Advance shall be in a minimum amount of
$100,000 or any amount in excess thereof and shall be made on the date specified
in the Borrowing Base Certificate requesting such Revolving Advance, or
telephonic notice confirmed in writing, as described in Section 1.03 hereof.

                  Section I.2. Revolving Commitment and Borrowing Limit. (a) The
Revolving Loan at any time shall not exceed an amount equal to the lesser of (i)
$25,000,000 (such amount, or such greater or lesser amount after giving effect
to any increase or decrease pursuant to the provisions of Section 1.02(d) and
(e) hereof, the "REVOLVING COMMITMENT"), and (ii) the Borrowing Base as of such
time (the lesser of (i) and (ii) being the "BORROWING LIMIT").

                  (b) Subject to the limitations herein and of Exhibit II
hereof, the Borrower may borrow, repay (without premium or penalty) and reborrow
under the Revolving Commitment. The Revolving Loan shall not exceed, and the
Lender shall not have any obligation to make any Revolving Advance which shall
result in the Revolving Loan being in excess of, the Borrowing Limit.

                  (c) If at any time the Revolving Loan exceeds the Borrowing
Limit at such time, the Borrower shall promptly, in accordance with Article II
hereof, eliminate such excess by paying an amount equal to such excess until
such excess is eliminated in full.

                  (d) The Borrower may request the Lender to increase the
Revolving Commitment by up to $25,000,000 and the Lender, in its sole discretion
upon any such request, may decide to increase the Revolving Commitment. Lender
shall respond, in writing, within five (5) Business Days after the date Lender
has received all




                                        1
<PAGE>   5

of the information reasonably requested by the Lender to make such
determination. Each such increase shall be in an amount equal to (i) $2,500,000
or an integral multiple thereof if, as of the time of such request, the
Revolving Commitment is less than $35,000,000 or (ii) $5,000,000 or an integral
multiple thereof if, as of the time of such request, the Revolving Commitment is
$35,000,000 or greater, and upon the effective date of such increase the
Borrower shall pay to the Lender a fee in an amount equal to 1.00% of any such
increase to the Revolving Commitment.

                  Section I.3. Notice of Borrowing; Borrowing Base Certificate.
Whenever the Borrower desires a Revolving Advance be made, the Borrower shall
give the Lender, (A) not later than 10:30 a.m. (New York City time) on the
proposed Funding Date of the Revolving Advance, written notice, or telephonic
notice from an Authorized Representative confirmed promptly by a Written Notice
(which notice, in each case, shall be irrevocable) of its desire to make a
borrowing of a Revolving Advance. Each notice of borrowing under this Section
1.03 shall (i) be indicated on a fully completed Borrowing Base Certificate
signed by the Borrower and dated as of such date, and shall specify the proposed
Funding Date (which in each instance shall be a Business Day) and the amount of
such Borrowing.

                  Section I.4. Termination of Revolving Commitment. On the
Maturity Date, the Revolving Commitment shall be canceled automatically and the
Revolving Loan shall become due and payable in full. In addition, prior to the
Maturity Date, the Borrower may terminate the Revolving Commitment pursuant to
Section 5.07(c). Upon such cancellation, the Revolving Loan (together with all
other Lender Debt) shall become, without further action by any Person,
immediately due and payable together with all accrued interest thereon and any
fees (including without limitation, the Early Termination Fee), premiums,
charges or costs provided for hereunder with respect thereto.

                  Section I.5. Interest and Fees. (a) Interest. The Borrower
shall pay interest on the on the average daily Outstanding Balance of the
Revolving Loan during the prior Month on (i) each Interest Payment Date and (ii)
the Maturity Date (whether by acceleration or otherwise), in each case, at an
interest rate per annum equal to LIBOR plus the Applicable Margin, in each case,
as in effect for the applicable Interest Period.

                  (b) Default Interest. Notwithstanding anything to the contrary
contained herein, while any Event of Default is continuing, interest on the
Revolving Loan shall be payable on demand at a rate per annum equal to 2.50% in
excess of the rate then otherwise applicable to the Revolving Loan.

                  (c) Non-Utilization Fee. The Borrower shall pay to the Lender
on the first Business Day of each Month a fee (the "NON-UTILIZATION FEE") equal
to 0.50% per annum on the average amount, calculated on a daily basis, by which
the Revolving Commitment exceeded the Revolving Loan during the prior Month.

                  Section I.6. Voluntary Reductions. The Borrower may on any
Funding Date reduce the outstanding principal amount of the Revolving Loan;
provided, however, that the Borrower shall provide the Lender with at least 15
days' prior Written Notice to the extent such reduction shall be more than 20%
of the then outstanding principal amount of the Revolving Loan

                  Section I.7. Computation of Interest. (a) Interest on the
Revolving Loan and fees and other amounts calculated by the Lender on the basis
of a rate per annum shall be computed on the basis of actual days elapsed over a
360-day year.

                  (b) Whenever any payment to be made hereunder or under any
other Document shall be stated to be due and payable on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day and
such extension of time shall in such case be included in computing interest on
such payment.

                  Section I.8. Procedures for Payment. (a) Each payment
hereunder shall be made not later than 12:00 noon (New York City time) on the
day when due in lawful money of the United States of America to the Lender
without counterclaim, offset, claim or recoupment of any kind and free and clear
of, and without deduction for, any present or future withholding or other taxes,
duties or charges of any nature imposed on such payments or prepayments by or on
behalf of any Governmental Entity thereof or therein, except for Excluded Taxes.
If any such




                                       2
<PAGE>   6

taxes, duties or charges are so levied or imposed on any payment to the Lender,
the Borrower will make additional payments in such amounts as may be necessary
so that the net amount received by the Lender, after withholding or deduction
for or on account of all taxes, duties or charges, including deductions
applicable to additional sums payable under this Section 1.08, will be equal to
the amount provided for herein. Whenever any taxes, duties or charges are
payable by the Borrower with respect to any payments hereunder, the Borrower
shall furnish promptly to the Lender information, including certified copies of
official receipts (to the extent that the relevant governmental authority
delivers such receipts), evidencing payment of any such taxes, duties or charges
so withheld or deducted. If the Borrower fails to pay any such taxes, duties or
charges when due to the appropriate taxing authority or fails to remit to the
Lender the required information evidencing payment of any such taxes, duties or
charges so withheld or deducted, the Borrower shall indemnify the Lender for any
incremental taxes, duties, charges, interest or penalties that may become
payable by the Lender as a result of any such failure.

                  (b) Notwithstanding anything to the contrary contained in this
Agreement, the Borrower agrees to pay any present or future stamp or documentary
taxes, any intangibles tax or any other sales, excise or property taxes, charges
or similar levies now or hereafter assessed that arise from and are attributable
to any payment made hereunder or from the execution, delivery of, or otherwise
with respect to, this Agreement or any other Documents and any and all recording
fees relating to any Documents securing any Lender Debt ("OTHER TAXES").

                  (c) The Borrower shall indemnify the Lender for the full
amount of any taxes, duties or charges other than Excluded Taxes (including,
without limitation, any taxes other than Excluded Taxes imposed by any
jurisdiction on amounts payable under this Section 1.08) duly paid or payable by
the Lender and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto. Indemnification payments shall be
made within 30 days from the date the Lender makes written demand therefor.

                  (d) Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 1.08 shall survive the payment in full of principal
and interest hereunder.

                  Section I.9. Indemnities. (a) The Borrower hereby agrees to
indemnify the Lender on demand against any loss or expense which the Lender or a
branch or an Affiliate of the Lender may sustain or incur as a consequence of:
(i) any default in payment or prepayment of the principal amount of any
Revolving Advance made to it or any portion thereof or interest accrued thereon,
as and when due and payable (at the due date thereof, by irrevocable notice of
payment or prepayment, or otherwise); (ii) the effect of the occurrence of any
Event of Default upon any Revolving Advance made to it; (iii) the payment or
prepayment of the principal amount of any Revolving Advance made to it or any
portion thereof; or (iv) the failure by the Borrower to accept a Revolving
Advance after it has requested such borrowing, conversion or renewal; in each
case including, but not limited to, any loss or expense sustained or incurred in
liquidating or employing deposits from third parties acquired to effect or
maintain such Revolving Advance or any portion thereof. The Lender shall provide
to the Borrower a statement, supported when applicable by documentary evidence,
explaining the amount of any such loss or expense it incurs, which statement
shall be conclusive absent manifest error.

                  (b) The Borrower hereby agrees to indemnify and hold harmless
the Lender, the Program Manager, the Master Servicer and their respective
Affiliates, directors, officers, agents, representatives, counsel and employees
and each other Person, if any, controlling them or any of their respective
Affiliates within the meaning of either Section 15 of the Securities Act of
1933, as amended, or Section 20(a) of the Exchange Act of 1934, as amended (each
an "INDEMNIFIED PARTY"), from and against any and all losses, claims, damages,
costs, expenses (including reasonable counsel fees and disbursements) and
liabilities which may be incurred by or asserted against such Indemnified Party
with respect to or arising out of the commitments hereunder to make the
Revolving Advances, or the financings contemplated hereby, the other Documents,
the Collateral (including, without limitation, the use thereof by any of such
Persons or any other Person, the exercise by the Lender of rights and remedies
or any power of attorney with respect thereto, and any action or inaction of the
Lender under and in accordance with any Documents), the use of proceeds of any
financial accommodations provided hereunder, any investigation, litigation or
other proceeding (brought or threatened) relating thereto, or the role of any
such Person or Persons in connection with the foregoing, whether or not they or
any other Indemnified Party is named as a party to any legal action or
proceeding ("CLAIMS"). The Borrower will not, however, be responsible to any
Indemnified





                                       3
<PAGE>   7

Party hereunder for any Claims to the extent that a court having jurisdiction
shall have determined by a final nonappealable judgment that any such Claim
shall have arisen out of or resulted solely from (a)(i) actions taken or omitted
to be taken by such Indemnified Party by reason of the bad faith, willful
misconduct or gross negligence of any Indemnified Party, or (ii) in violation of
any law or regulation applicable to such Indemnified Party (except to the extent
that such violation is attributable to any breach of any representation,
warranty or agreement by or on behalf of the Borrower, any Provider or any of
their respective designees, in each case, as determined by a final nonappealable
decision of a court of competent jurisdiction), or (b) a successful claim by the
Borrower or any Provider against such Indemnified Party ("EXCLUDED CLAIMS").
Further, should any employee of the Lender, in connection with such employee's
employment by the Lender, be involved in any legal action or proceeding in
connection with the transactions contemplated hereby (other than relating to an
Excluded Claim), the Borrower hereby agrees to pay to the Lender such reasonable
per diem compensation as the Lender shall request for each employee for each day
or portion thereof that such employee is involved in preparation and testimony
pertaining to any such legal action or proceeding. The Indemnified Party shall
give the Borrower prompt Written Notice of any Claim setting forth a description
of those elements of the Claim of which such Indemnified Party has knowledge.
The Lender, as an Indemnified Party shall be permitted hereunder to select
counsel to defend such Claim at the expense of the Borrower and, if such
Indemnified Party shall decide to do so, then all such Indemnified Parties shall
select the same counsel to defend such Indemnified Parties with respect to such
Claim; provided, however, that if any such Indemnified Party shall in its
reasonable opinion consider that the retention of one joint counsel as aforesaid
shall result in a conflict of interest, such Indemnified Party may, at the
expense of the Borrower, select its own counsel to defend such Indemnified Party
with respect to such Claim. The Indemnified Parties and the Borrower and their
respective counsel shall cooperate with each other in all reasonable respects in
any investigation, trial and defense of any such Claim and any appeal arising
therefrom.

                  Section I.10. Telephonic Notice. Without in any way limiting
the Borrower's obligation to confirm in writing any telephonic notice of a
borrowing, conversion or renewal, the Lender may act without liability upon the
basis of telephonic notice believed by the Lender in good faith to be from an
Authorized Representative of the Borrower prior to receipt of written
confirmation.

                  Section I.11. Maximum Interest. (a) No provision of this
Agreement shall require the payment to the Lender or permit the collection by
the Lender of interest in excess of the maximum rate of interest from time to
time permitted (after taking into account all consideration which constitutes
interest) by laws applicable to the Lender Debt and binding on the Lender (such
maximum rate being the Lender's "MAXIMUM PERMISSIBLE RATE").

                  (b) If the amount of interest (computed without giving effect
to this Section 1.11) payable on any Interest Payment Date in respect of the
preceding interest computation period would exceed the amount of interest
computed in respect of such period at the Maximum Permissible Rate, the amount
of interest payable to the Lender on such date in respect of such period shall
be computed at the Maximum Permissible Rate.

                  (c) If at any time and from time to time: (i) the amount of
interest payable to the Lender on any Interest Payment Date shall be computed at
the Maximum Permissible Rate pursuant to the preceding subsection (b); and (ii)
in respect of any subsequent interest computation period the amount of interest
otherwise payable to the Lender would be less than the amount of interest
payable to the Lender computed at the Maximum Permissible Rate, then the amount
of interest payable to the Lender in respect of such subsequent interest
computation period shall continue to be computed at the Maximum Permissible Rate
until the amount of interest payable to the Lender shall equal the total amount
of interest which would have been payable to the Lender if the total amount of
interest had been computed without giving effect to the preceding subsection
(b).


                                   ARTICLE II.
                           COLLECTION AND DISTRIBUTION

                  Section II.1. Collections on the Receivables. The Lender shall
be entitled with respect to all Receivables, (i) to receive and to hold as
collateral all Receivables and all Collections on Receivables in accordance with
the terms hereof, and (ii) to have and to exercise any and all rights to
collect, record, track and, during the continuance of an Event of Default, take
all actions to obtain Collections with respect to all Receivables.

12:00 p.m. (New York City time) on the immediately prior Business Day as
follows: FIRST, to the Lender, an amount in cash equal to fees and interest that
are due and payable as of such Business Day and have not otherwise been paid in

until such amount is paid in full; THIRD, to the Lender, an amount in cash equal
to the reduction of the principal amount of the Revolving Loan directed by the
Borrower to be repaid on such Business Day pursuant to Section 1.02(b), if any,
until such amount has been paid in full; FOURTH, to the Lender, an amount in
cash equal to the payment of any Lender Debt due and payable on such Business
Day, if any, until such amount has been paid in full; and FIFTH, to the
Borrower, all remaining amounts of Collections.

                  Section II.3. Distribution of Funds at the Maturity Date or
Upon an Event of Default. At the Maturity Date or upon the occurrence and during
the continuance of an Event of Default, subject to the rights and remedies of
the Lender pursuant to Section 3.02 hereof, the Lender shall distribute any and
all Collections as follows: FIRST, to the Lender, an amount in cash equal to any
and all accrued fees and collection costs as set forth in Sections 1.05 and
5.05, until such amount has been paid in full; SECOND, to the Lender, an amount
in cash equal to all accrued and unpaid interest on the Revolving Loan (at the

THIRD, to the Lender, an amount in cash equal to the principal amount of the
Revolving Loan, until such amount is paid in full; FOURTH, to the Lender, an

all remaining amounts of Collections.

                  Section II.4. Distributions to the Borrower Generally.
Distributions to the Borrower on each Business Day shall be deposited in the
Borrower Account.

                                EVENTS OF DEFAULT

                  Section III.1. Representations and Warranties; Covenants. The
Borrower makes on the Initial Funding Date and on each subsequent Funding Date,
the representations and warranties set forth in Exhibit III hereto, and hereby
agrees to perform and observe the covenants set forth in Exhibit IV hereto.

                  Section III.2. Events of Default; Remedies. (a) If any Event
of Default shall occur and be continuing, the Lender may, by Written Notice to
the Borrower, take either or both of the following actions: (x) declare the
Maturity Date to have occurred, and (y) without limiting any rights hereunder
and subject to applicable law, replace the Borrower or the Borrower's agent, as
the case may be, in its performance of any or all of the "Primary Servicer
Responsibilities" under the RPTA (which replacement may be effectuated through
the outplacement to a qualified and experienced third-party of all back office
duties, including billing, collection and processing responsibilities, and
access to all personnel, hardware and software utilized in connection with such
responsibilities); provided, that with respect to the Event of Default in clause
(h) of Exhibit V, the Maturity Date shall be deemed to have occurred
automatically and without notice. Upon any such declaration or designation, the
Lender shall have, in addition to the rights and remedies which it may have
under this Agreement, all other rights and remedies provided after default under
the UCC and under other applicable law, which rights and remedies shall be
cumulative.

                  (b) Right of Set-Off. The Borrower hereby irrevocably
authorizes and instructs the Lender to set-off the full amount of any Lender
Debt due and payable against (i) any Collections, or (ii) the principal amount
of any Revolving Advance requested on or after such due date. No further
notification, act or consent of any nature whatsoever is required prior to the
right of the Lender to exercise such right of set-off; provided, however, a
member of the Lender Group shall notify the Borrower: (1) a set-off pursuant to
this Section 3.02 occurred, (2) the amount of such set-off and (3) a description
of the Lender Debt that was due and payable.

                  Section III.3. Attorney-in-Fact. The Borrower hereby
irrevocably designates and appoints the Lender, the Master Servicer and each
other Person in the Lender Group, to the extent permitted by applicable law




                                       5

and regulation, as the Borrower's attorneys-in-fact, which irrevocable power of
attorney is coupled with an interest, with authority, upon the continuance of an
Event of Default (and to the extent not prohibited under applicable law and
regulations) to (i) endorse or sign the Borrower's name to financing statements,
remittances, invoices, assignments, checks, drafts, or other instruments or
documents in respect of the Receivables, (ii) notify Obligors to make payments
on the Receivables directly to the Lender, and (iii) bring suit in the
Borrower's name and settle or compromise such Receivables as the Lender or the
Master Servicer may, in its discretion, deem appropriate.


                                   ARTICLE IV.
                                    SECURITY

                  Section IV.1. Grant of Security Interest. (a) As collateral

owned or hereafter acquired, (iii) any and all amounts held in any accounts
maintained at Fleet Bank. N.A., Wachovia Bank, N.A., Mellon Bank, N.A., The
Chase Manhattan Bank or any other bank in respect of any of the foregoing or in
compliance with any terms of this Agreement, (iv) all of the Additional
Collateral, (v) each Lender Lockbox and Lender Lockbox Account and (vi) all
proceeds of the foregoing (all of the foregoing, the "COLLATERAL"). This
Agreement shall be deemed to be a security agreement as understood under the
UCC.

                  (b) The Borrower agrees to execute, and hereby authorizes the
Lender to file, one or more financing statements or continuation statements or
amendments thereto or assignments thereof in respect of the Lien created
pursuant to this Section 4.01 which may at any time be required or, in the
opinion of the Lender, be desirable, and to do so without the signature of the
Borrower where permitted by law.


                                   ARTICLE V.
                                  MISCELLANEOUS

                  Section V.1. Amendments, etc. (a) No amendment or waiver of
any provision of this Agreement or consent to any departure therefrom by a party
hereto shall be effective unless in a writing signed by the Lender and the
Borrower and then such amendment, waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given. No failure
on the part of the Lender or the Borrower to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right.

                  (b) The parties hereto agree to make any change, modification
or amendment to this Agreement as may be requested by Fitch, Inc. or any other
rating agency then rating the healthcare financing program of the Lender, so
long as any such change, modification or amendment does not materially adversely
affect the parties hereto.

                  Section V.2. Notices, etc. All notices and other
communications hereunder shall, unless otherwise stated herein, be in writing
(which may include facsimile communication) and shall be faxed or delivered, (i)
to each party hereto (and the Lender hereby agrees that notices to or for its
benefit may be delivered to the Program Manager and such delivery to the Program
Manager shall be deemed received by the Lender), at its address set forth under
its name on the signature pages hereof or at such other address as shall be
designated by such party in a Written Notice to the other parties hereto, and
(ii) to the Program Manager and the Master Servicer at the addresses set forth
on Schedule I attached hereto and as such schedule may be amended from time to
time by the Lender. Notices and communications by facsimile shall be effective
when sent (and shall be immediately followed by hard copy sent by regular mail),
and notices and communications sent by other means shall be effective when
received.

                  Section V.3. Assignability. (a) This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective
permitted successors and assigns.

cost and expense, upon the request of the Lender, duly execute and deliver, or
cause to be duly executed and delivered, to the Lender such further instruments
and do and cause to be done such further acts as may be necessary or proper in
the reasonable opinion of the Lender to carry out more effectively the
provisions and purposes of this Agreement.

                  Section V.5. Costs and Expenses; Collection Costs. (a) The
Borrower agrees to pay on demand (i) all reasonable non-legal costs and expenses
in connection with the preparation, execution and delivery of this Agreement;
(ii) the reasonable fees and out-of-pocket expenses of counsels for the Lender
and its Affiliates in connection with this transaction; and (iii) all reasonable
costs and expenses, if any (including reasonable counsel fees and expenses), of
the Lender and its Affiliates in connection with any waiver, modification,
supplement or amendment hereto, or the enforcement of this Agreement. The
Borrower further agrees to pay on the Initial Funding Date (and with respect to
costs and expenses incurred following the Initial Funding Date, within seven
days of demand therefor) (a) all reasonable costs and expenses incurred by the
Lender or its agent in connection with periodic audits of the Receivables, (b)
all reasonable costs and expenses (not to exceed $3,000 in any fiscal year of
the Borrower) incurred by the Master Servicer or the Program Manager to
accommodate any significant coding or data system changes made by the Borrower
that would affect the transmission or interpretation of data received through
the interface, and (c) all reasonable costs and expenses incurred by the Lender
for additional time and material expenses of the Master Servicer resulting from
a lack of either commercially reasonably cooperation or responsiveness of the
Borrower to agreed-upon protocol and schedules with the Master Servicer;
provided, that the Borrower has received Written Notice of the alleged lack of
cooperation or responsiveness and has been provided the opportunity to correct
such problems.

                  (b) In the event that the Lender shall retain an attorney or
attorneys to collect, enforce, protect, maintain, preserve or foreclose its
interests with respect to this Agreement, any other Documents, any Lender Debt,
any Receivable or the Lien on any Collateral or any other security for the
Lender Debt or under any instrument or document delivered pursuant to this
Agreement, or in connection with any Lender Debt, the Borrower shall pay all of
the reasonable costs and expenses of such collection, enforcement, protection,
maintenance, preservation or foreclosure, including reasonable attorneys' fees,
which amounts shall be part of the Lender Debt, and the Lender may take judgment
for all such amounts. The attorney's fees arising from such services, including
those of any appellate proceedings, and all reasonable expenses, costs, charges
and other fees incurred by such counsel in any way or with respect to or arising
out of or in connection with or relating to any of the events or actions
described in this Section 5.05 shall be payable by the Borrower to the Lender on
demand (with interest accruing from the earlier of two Business Days following
(i) the date of such demand and (ii) the date the Borrower became aware of the
incurrence of such cost), and shall be additional obligations under this
Agreement. Without limiting the generality of the foregoing, such expenses,
costs, charges and fees may include: recording costs, appraisal costs, paralegal
fees, costs and expenses; accountants' fees, costs and expenses; court costs and
expenses; photocopying and duplicating expenses; court reporter fees, costs and
expenses; long distance telephone charges; air express charges; telegram
charges; telecopier charges; secretarial overtime charges; and expenses for
travel, lodging and food paid or incurred in connection with the performance of
such legal services.

                  Section V.6. Confidentiality. (a) The Borrower and the Lender
hereby acknowledge that this Agreement and documents delivered hereunder or
under the Provider Documents (including, without limitation, any information
relating to the Borrower, any member of the Lender Group or any Provider)
contain confidential and proprietary information. Unless otherwise required by
applicable law, the Borrower and the Lender each hereby agrees to maintain the
confidentiality of this Agreement (and all drafts and other documents delivered
in connection therewith including, without limitation, any information relating
to the Borrower, any member of the Lender Group or any Provider delivered
hereunder or under the Provider Documents) in communications with third parties
and otherwise and to take all reasonable actions to prevent the unauthorized use
or disclosure of and to protect the confidentiality of such confidential
information; provided, that, such confidential information may be disclosed to
(i) the Borrower's legal counsel, accountants and auditors, the Providers under
the Provider Documents, and the Providers' investors, creditors, legal counsel,
accountants and auditors, (ii) the Program Manager, the Person then fulfilling
the "Primary Servicer Responsibilities" under the Provider Documents, each
member of the Lender Group, investors in and creditors of the Lender,

respective legal counsel and auditors, (iii) any Person, if such information
otherwise becomes available to such Person or publicly available through no
fault of any party governed by this Section 5.06, (iv) any Governmental




                                       7
<PAGE>   11

Entity requesting such information, and (v) any other Person with the written
consent of the other party, which consent shall not be unreasonably withheld,
and provided further that the Borrower shall not disclose such confidential
information to any financial adviser, except with the consent of Lender, which
will not be unreasonably withheld. Notwithstanding the foregoing, the parties
hereto agree that the Parent, as a public company, may make such disclosure as
is required by state and federal law, including, but not limited to, such
filings as are required by the Securities and Exchange Commission.

                  (b) The Borrower understands and agrees that the Lender or the
Lender Group may suffer irreparable harm if the Borrower breaches its
obligations under Section 5.06(a) and that monetary damages shall be inadequate
to compensate the Lender for such breach. Accordingly, the Borrower agrees that,
in the event of a breach by the Borrower of Section 5.06(a), the Lender (or the
applicable member of the Lender Group, as the case may be), in addition and not
in limitation of its rights and remedies under law, shall be entitled to a
temporary restraining order, preliminary injunction and permanent injunction to
prevent or restrain any such breach.

                  Section V.7. Term and Termination; Early Termination Fee. (a)
This Agreement shall have an initial term commencing on the Initial Funding Date
and expiring on April 6, 2004 (the "INITIAL TERM"). Thereafter, the term of this
Agreement shall be automatically extended for annual successive terms (each a
"RENEWAL TERM") commencing on the last day of the Initial Term or a Renewal
Term, as the case may be, and expiring on the date twelve (12) Months
thereafter, unless the Lender or the Borrower provides Written Notice not less
than forty-five (45) days prior to the expiration of the Initial Term or a
Renewal Term, as the case may be, that such Person does not intend to extend the
term of this Agreement; provided, however, that if an Event of Default shall
have occurred and be continuing at the end of the Initial Term or a Renewal
Term, as the case may be, this Agreement will not automatically be extended
without the prior written consent of the Lender. The Borrower shall pay to the
Lender on the first day of each Renewal Term a fee equal to 0.50% of the
Revolving Commitment then in effect.

                  (b) The obligations of the Lender under this Agreement shall
continue in full force and effect from the date hereof until the Maturity Date.
Upon the payment in full of all Lender Debt, the Lender shall take all actions
and deliver all assignments, certificates, releases, notices and other
documents, at the Borrower's expense, as the Borrower may reasonably request to
effect such termination.

                  (c) The Borrower may terminate this Agreement at any time
prior to the Maturity Date upon (i) lapse of not less than thirty days' prior
Written Notice (which shall be irrevocable) to the Lender of default of the
commitment by the Lender pursuant to Article I hereof to make Revolving Advances
and (ii) payment in full of all Lender Debt, including all applicable fees,
charges, premiums and costs, all as provided hereunder, and in such occurrence
of clauses (i) and (ii) the commitment hereunder shall be deemed to be
terminated.

                  (d) If the Revolving Commitment is terminated or the Revolving
Loan becomes due and payable prior to the scheduled end of the Initial Term or
Renewal Term (including by reason of an Event of Default) the Borrower shall pay
to the Lender the Early Termination Fee; provided however that if the Lender
refuses a request by the Borrower to increase the Revolving Commitment pursuant
to Section 1.02(d) hereof and (i) within 105 days of the date the Borrower
receives written notice of the Lender's refusal, the Borrower, the Providers or
the Parent consummate a financing arrangement with another lender or lenders
(the "ALTERNATIVE FINANCING") and (ii) the commitments of the lending parties
under the Alternative Financing is equal to or greater than the Revolving
Commitment requested by the Borrower and all such commitments are effective
immediately upon the consummation of the Alternative Financing, no Early
Termination Fee shall be payable.

                  (e) The termination of this Agreement shall not affect any
rights of the Lender or any obligations of the Borrower arising on or prior to
the effective date of such termination, and the provisions hereof shall continue
to be fully operative until all Lender Debt incurred on or prior to such
termination has been paid and performed in full.

                  (f) Upon the giving of notice of an Event of Default under
this Agreement, all Lender Debt shall be due and payable on the date of the
Event of Default specified in such notice. Upon the (i) the termination of all
commitments and obligations of the Lender, and (ii) the indefeasible payment in
full of all Lender Debt, the Lender shall, at the Borrower's request and sole
cost and expense, execute and deliver to the Borrower such documents as the
Borrower shall reasonably request to evidence such termination.

<PAGE>   12

                  (g) The Liens and rights granted to the Lender hereunder shall
continue in full force and effect, notwithstanding the termination of this
Agreement, until all of the Lender Debt has been indefeasibly paid in full in
cash.

                  (h) All indemnities representations, warranties, covenants,
waivers and agreements contained herein shall survive termination hereof unless
otherwise provided.

                  (i) Notwithstanding the foregoing, if after receipt of any
payment of all or any part of the Lender Debt, the Lender is for any reason
compelled to surrender such payment to any Person or entity because such payment
is determined to be void or voidable as a preference, an impermissible setoff, a
diversion of trust funds or for any other reason, this Agreement shall continue
in full force (except that the Revolving Commitment of the Lender shall have
been terminated), and the Borrower shall be liable to, and shall indemnify and
hold the Lender harmless for the amount of such payment surrendered until the
Lender shall have been finally and irrevocably paid in full. The provisions of
the foregoing sentence shall be and remain effective notwithstanding any
contrary action which may have been taken by the Lender in reliance upon such
payment, and any such contrary action so taken shall be without prejudice to the
Lender's rights under this Agreement and shall be deemed to have been
conditioned upon such payment having become final and irrevocable.

                  Section V.8. No Liability of Lender. (a) Neither this
Agreement nor any document executed in connection herewith shall constitute an
assumption by the Lender of any obligation of the Borrower to any Obligor or the
Providers.

                  (b) Notwithstanding any other provision herein, no recourse
under any obligation, covenant, agreement or instrument of the Lender contained
herein or with respect hereto shall be had against any Related Person whether
arising by breach of contract, or otherwise at law or in equity (including any
claim in tort), whether express or implied, it being understood that the
agreements and other obligations of the Lender herein and with respect hereto
are solely its corporate obligations; provided, however, nothing herein above
shall operate as a release of any liability which may arise as a result of such
Related Person's gross negligence or willful misconduct. The provisions of this
Section 5.08 shall survive the termination of this Agreement.

                  Section V.9. Entire Agreement; Severability. (a) This
Agreement, including all exhibits and schedules hereto and the documents
referred to herein, embody the entire agreement and understanding of the parties
concerning the subject matter contained herein. This Agreement supersedes any
and all prior agreements and understandings between the parties, whether written
or oral.

                  (b) If any provision of this Agreement shall be declared
invalid or unenforceable, the parties hereto agree that the remaining provisions
of this Agreement shall continue in full force and effect.

                  Section V.10. GOVERNING LAW. THIS AGREEMENT SHALL, IN
ACCORDANCE WITH SECTION 5-1401 OF THE GENERAL OBLIGATION LAW OF THE STATE OF NEW
YORK, BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO ANY
CONFLICTS OF LAWS PRINCIPLES THEREOF THAT WOULD CALL FOR THE APPLICATION OF THE

PERFECTION OF THE SECURITY INTERESTS GRANTED HEREUNDER, OR REMEDIES RELATED
THERETO, IN RESPECT OF ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A
JURISDICTION OTHER THAN THE STATE OF NEW YORK.

               Effect;

                              (viii) as soon as possible and in any event within

               year of the Borrower, a certificate from the chief financial
               officer of the Borrower stating that to his knowledge no Servicer
               Termination Event has occurred and exists as of the end of such
               fiscal year, or if in his opinion such a Servicer Termination
               Event has occurred and is continuing, a statement as to the
               nature thereof; and

                              (x) such other information respecting the

promptly notify the Master Servicer (and modify the next Borrowing Base
Certificate to be delivered hereunder) in the event of any action, suit,
proceeding, dispute, set-off, deduction, defense or counterclaim, in excess of

with respect to Receivables related to such Obligor. The Borrower shall make, or
cause to be made, all payments to the Obligors necessary to prevent the Obligors
from offsetting any earlier overpayment to the Borrower or the Providers against
any amounts the Obligors owe on any Receivables.

                  (l) Officer's Certificate. On the dates the financial
statements referred to in clause (j) above are to be delivered after the Initial
Funding Date, the chief financial officer (or in the case of the Weekly Report

shall, at its expense, promptly execute and deliver all further instruments and

may reasonably request, from time to time, in order to perfect, protect or more
fully evidence the Lender's security interest in the Collateral, or to enable
the Lender or the Program Manager to exercise or enforce the rights of the
Lender hereunder or in the Collateral. Without limiting the generality of the
foregoing, the Borrower will upon the request of the Program Manager execute and
file such UCC financing or continuation statements, or amendments thereto or
assignments thereof, and such other instruments or notices, as may be, in the
opinion of the Program Manager, necessary or appropriate. The Borrower hereby
authorizes the Program Manager to file one or more financing or continuation
statements and amendments thereto and assignments thereof, relative to all or
any of the Collateral now existing or hereafter arising without the signature of
the Borrower where permitted by law. If the Borrower fails to perform any of its
agreements or obligations under the Agreement, the Program Manager may (but
shall not be required to) itself perform, or cause performance of, such
agreement or obligation, and the expenses of the Program Manager incurred in
connection therewith shall be payable by the Borrower.

                  (n) Merger, Consolidation. The Borrower shall not merge with
or into, consolidate with or into, or enter into any agreement to merge or
consolidate with or into, another Person, or convey, transfer, lease or
otherwise dispose of all or substantially all of its assets (whether now owned
or hereafter acquired).

                  (o) No "Instruments". The Borrower shall not take any action
which would allow, result in or cause any Eligible Receivable to be evidenced by
an "instrument" within the meaning of the UCC of the applicable jurisdiction.

                  (p) Preservation of Company Existence. The Borrower shall
preserve and maintain its existence, rights, franchises and privileges in the
jurisdiction of its organization, and qualify and remain qualified in good
standing as a foreign corporation in each jurisdiction where the failure to
preserve and maintain such existence, rights, franchises, privileges and
qualification would have a Material Adverse Effect.

                  (q) Provider Documents. The Borrower will, at its sole
expense, timely and fully perform and comply with all provisions, covenants and
other promises required to be observed by it under the Provider Documents,
maintain the Provider Documents in full force and effect, enforce the Provider
Documents in accordance with its terms, take all such action to such end as may
be from time to time reasonably requested by the Lender, and make to any party
to the Provider Documents such demands and requests for information and reports
or for action as the Borrower is entitled to make thereunder and as may be from
time to time reasonably requested by the Lender. The Borrower shall not permit
any waiver, modification or amendment of the Provider Documents.

                                   EXHIBIT VI.

                              ELIGIBILITY CRITERIA

                  The following shall constitute the eligibility criteria for
acceptance of Receivables for financing and inclusion in the Borrowing Base
under the Agreement (the "ELIGIBILITY CRITERIA"):

                  (a) The information provided by the Borrower with respect to
each such Receivable is complete and correct and all documents, attestations and
agreements relating thereto that have been delivered to the Lender are true and
correct. Except with respect to Unbilled Receivables sold or contributed to the
Borrower, the related Provider has billed the applicable Obligor and has
delivered to such Obligor all requested supporting claim documents with respect
to such Receivable and no amounts with respect to such Receivable have been paid
as of the date and time of the inclusion of such Receivable in the Borrowing
Base. Each Provider has, or has the right to use, valid provider identification
numbers and licenses to generate valid Receivables. Except with respect to
Unbilled Receivables sold or contributed to the Borrower, all information set
forth in the bill and supporting claim documents with respect to such Receivable
is true, complete and correct; if additional information is requested by the
Obligor, the Borrower (or the related Provider) has or will promptly provide the
same, and if any error has been made with respect to such information, the
Borrower (or the related Provider) will promptly correct the same and, if
necessary, rebill such Receivable. The Obligor of each such Receivable has duly
and validly executed the time card related to such Receivable.

                  (b) Each such Receivable (i) is payable, in an amount not less
than its Expected Net Value, by the Obligor identified by the related Provider
as being obligated to do so, (ii) is based on an actual and bona fide rendition
of services or sale of goods to the Obligor by the related Provider in the
ordinary course of business, (iii) is denominated and payable only in U.S.
dollars in the United States and (iv) is an account or general intangible within
the meaning of the UCC of the state in which the related Provider has its
principal place of business and is not evidenced by any instrument or chattel
paper.

                  (c) Each such Receivable (i) is not the subject of any action,
suit, proceeding or dispute (pending or threatened), setoff, counterclaim,
defense, abatement, suspension, deferment, deductible, reduction or termination
by the Obligor thereof (other than any portion of such Receivable which is being
disputed by the Obligor which portion shall not be an "Eligible Receivable"),
(ii) is not past, or within 60 days of, the statutory limit for collection
applicable to the Obligor thereof or is not aged more than 180 days from its
Last Service Date, and (iii) has been billed (or, in the case of Unbilled
Receivables sold or contributed to the Borrower, shall be billed) to the Obligor
thereof on a date fewer than fourteen (14) days after the Last Service Date
provided that with respect to Receivables billed on a monthly cycle at the
request of the Obligor, such Receivable has been billed (or, if such Receivable
is an Unbilled Receivable and has been sold or contributed to the Borrower,
shall be billed) within forty-five (45) days after the Last Service Date.

                  (d) Neither the Borrower nor the related Provider has any
guaranty of, letter of credit providing credit support for, or collateral
security for, such Receivable, other than any such guaranty, letter of credit or
collateral security as has been assigned to the Lender, and any such guaranty,
letter of credit or collateral security is not subject to any Lien in favor of
any other Person.

                  (e) The relevant Provider has provided (or on the day such
Receivable is included in the Borrowing Base, is providing) the goods and
services related to such Receivable to the relevant Obligor.

                  (f) Intentionally omitted.

                  (g) The Obligor with respect to each such Receivable is (i)
not currently the subject of any bankruptcy, insolvency or receivership
proceeding (other than with respect to Priority DIP Receivables), nor is it
unable to make payments on its obligations when due, (ii) located in the United
States of America, (iii) not a subsidiary, parent or other Person that is an
Affiliate of any Provider and (iv) not the Obligor of Defaulted Receivables in
the past 12 Months (other than, for the purpose of this clause, as a result of
good faith disputes and discounts given in accordance with the Credit and
Collection Policy) which, in the aggregate, exceed 10% of the current gross
unpaid amount of all Eligible Receivables of such Obligor.




                                      VI-1
<PAGE>   38

                  (h) The financing of such Receivables hereunder is made in
good faith and without actual intent to hinder, delay or defraud present or
future creditors of the Borrower.

                  (i) The contract or other instrument obligating an Obligor to
make payment with respect to such Receivable (i) does not contain any provision
prohibiting the grant of a security interest in or the assignment of such
payment obligation from the relevant Provider to the Borrower, or from the
Borrower to the Lender, (ii) has been duly authorized and, together with such
Receivable, constitutes the legal, valid and binding obligation of the Obligor
in accordance with its terms, (iii) together with such Receivable, does not
contravene in any material respect any requirement of law applicable thereto,
and (iv) was in full force and effect and applicable to the Obligor at the time
the goods or services constituting the basis for such Receivable were sold or
performed.

                  (j) No consents by any third party to the sale of such
Receivable are required other than consents previously obtained in writing by
the Borrower, a copy of each such consent having been provided to the Lender.

                  (k) The inclusion of such Receivable in the Borrowing Base
would not increase the fraction expressed as a percentage where (i) the
numerator is the sum of the then outstanding principal amount of Eligible
Receivables for any Obligor (or group of Obligors) listed below included in the
Borrowing Base, and (ii) the denominator is the Borrowing Base for all Eligible
Receivables, above the corresponding maximum percentage listed below:

outstanding principal amount of Priority DIP Receivables included in the
Borrowing Base, and (ii) the denominator is the Borrowing Base for all Eligible
Receivables, above 2%.

still in effect on the applicable Funding Date has been made with respect to or
granted in any such Receivable.

                  (n) All personnel provided by any Provider to Obligors giving
rise to such Receivables are salaried employees of such Provider, are not
independent contractors of such Provider, and no Provider is aware of any claim
by any such personnel to be, or have the status of, an independent contractor.
