                         RECEIVABLES PURCHASE AGREEMENT

         This Receivables Purchase Agreement ("Agreement") is entered into as of
March 29, 2002 between American Reimbursement, LLC, a Delaware limited liability
company ("Buyer") and Chartwell Diversified Services, Inc., a Delaware
corporation ("Seller"), with reference to the following facts:

         Subject to Section 3 below, Seller is the owner of certain accounts
receivable as listed on SCHEDULE A hereto (the "A/R"). Seller desires to sell,
and Buyer desires to purchase, the A/R upon the terms and conditions set forth
in this Agreement.

         NOW, THEREFORE, in consideration of the foregoing, of the agreements
set forth herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Buyer and Seller agree as follows:

         1. SALE OF A/R. Seller hereby, sells, assigns, transfers, conveys and
sets over unto Buyer all of its right, title and interest in and to the A/R in
exchange for Buyer's agreement set forth herein to pay to Seller the Purchase
Price therefor.

         2. PAYMENT OF PURCHASE PRICE. Buyer hereby agrees to pay to Seller the
Purchase Price for the A/R as set forth in this Section 2. The "Purchase Price"
for each account receivable included in the A/R means the actual collections
made and received by or on behalf of Buyer on such account receivable. Within
two (2) business days of Buyer's receipt of any such collections, thirty percent
(30%) thereof shall be remitted directly to Seller (or in accordance with
Seller's written instructions). Buyer's obligation to pay to Seller the
remaining seventy (70%) of such collections shall be evidenced by a promissory
note made by Buyer to Seller, substantially in the form of EXHIBIT A hereto
(each a "Note"). All payments of the Purchase Price (including payments under
any Note) shall be made in accordance with the instructions set forth EXHIBIT B
hereto.

Seller expressly acknowledges and agrees that Buyer's obligation to pay the
Purchase Price is subject and subordinate to Buyer's assumption and
indemnification obligations under that certain Assumption and Indemnification
Agreement dated as of March 29, 2002 between Buyer and Med Diversified, Inc.

         3. REPRESENTATIONS; DISCLAIMER. Buyer expressly understands and agrees
that Seller makes no representations or warranties with respect to the A/R, the
documents evidencing or securing such A/R or otherwise, except that Seller
represents and warrants that it is transferring title to such accounts
receivable subject only to such interests as are reflected in the public
financing statement records.

         4. FURTHER ASSURANCES. Seller agrees to cooperate with Buyer and to
execute and deliver such additional instruments as may be reasonably necessary
in order to give effect to Buyer's acquisition of the A/R.

         5. MISCELLANEOUS. This Agreement and the Notes represent the entire
understanding of the parties with respect to the subject matter hereof, and may
be executed in counterparts (including counterparts delivered by facsimile),
each of which shall be considered an original but all of which taken together
shall constitute one and the same agreement. Any notice given by any party in
connection with this Agreement or any Note shall be effective only upon its
receipt by the other party and only if (a) given in writing and (b) personally
delivered or sent by United States mail, postage prepaid, and addressed to the
recipient at its address set forth beneath its signature to this Agreement,
which address may be changed pursuant to a notice given as provided herein. This
Agreement shall be governed by and construed in accordance with the laws of the
State of Delaware.

                                 PROMISSORY NOTE

$_____________________                                        ___________, _____

         1. FOR VALUE RECEIVED, the undersigned, American Reimbursement, LLC, a
Delaware limited liability company ("Borrower") promises to pay to Chartwell
Diversified Services, Inc., a Delaware corporation ("Lender"), or to Lender's
order, the principal sum of ___________________ DOLLARS ($_________), together
with interest on the unpaid principal hereof at the rate provided in Section 3
below. All payments under this Note shall be made by corporate check in
accordance with Lender's instructions. This Note is made pursuant to and is
subject to that certain Receivables Purchase Agreement dated as of March 29,
2002, between Lender, as Seller, and Borrower.

         2. PAYMENTS. The entire principal amount of this Note, together with
all accrued unpaid interest, shall be due and payable on [___________, ____](1).
Lender expressly acknowledges and agrees that Borrower's obligations under this
Note are subject and subordinate to Buyer's assumption and indemnification
obligations under that certain Assumption and Indemnification Agreement dated as
of March 29, 2002 between Borrower and Med Diversified, Inc.

         3. INTEREST. Interest on the unpaid principal balance of this Note
shall accrue at the rate equal to LIBOR as in effect from time to time. In the
event that Borrower fails to pay any amount under this Note when due (whether at
maturity, by acceleration or otherwise, such overdue amount shall bear interest
at the rate which is three percent (3%) per annum in excess of LIBOR.
Notwithstanding any other provision of this Note, in no event shall the interest
payable hereunder, whether before or after maturity, exceed the maximum interest
which, under applicable law, may be charged on this Note. To the extent that any
amount collected by Lender exceeds the maximum interest permitted under
applicable law, such excess shall be applied to reduce the outstanding principal
of this Note. As used herein, "LIBOR" means, for the period commencing on the
date hereof and ending 3 months thereafter, and for each successive 3-month
period, the 3-month LIBOR interest rate as quoted in THE WALL STREET JOURNAL on
the first day of such period.

         4. EVENTS OF DEFAULT. Any one or more of the following events shall
constitute an Event of Default by Borrower under this Note.

            (a) If Borrower fails to pay when due and payable or when declared
due and payable, any portion of the obligations hereunder, whether of principal
or interest (including any interest which, but for the provisions of the United
States Bankruptcy Code, would have accrued on such amounts); or

            (b) If any bankruptcy, reorganization, receivership or other
insolvency proceeding is commenced by or against Borrower.

--------
(1) Three years from issuance.

Upon the occurrence of an Event of Default, all amounts outstanding under this
Note shall, at the option of the holder hereof, become immediately due and
payable without notice or demand.

         5. MISCELLANEOUS. The indebtedness evidenced hereby shall be payable in
lawful money of the United States. Should any one or more provisions of this
Note be determined to be illegal or unenforceable, all other provisions shall
nevertheless remain effective.

         6. CHOICE OF LAW. This Note shall be governed by and construed in
accordance with the laws of the State of California, without giving effect to
the conflict of laws principles of such State.

         7. SUCCESSORS AND ASSIGNS. This Note shall bind Borrower and its
successors and assigns and shall inure to the benefit of Lender and its
successors and assigns; PROVIDED, HOWEVER, that Borrower may not assign this
Agreement or any rights or duties hereunder without Lender's prior written
consent and any prohibited assignment shall be absolutely void. No consent by
Lender to an assignment by Borrower shall release Borrower from its obligations.

         8. AMENDMENTS AND WAIVERS. No amendment, modification, termination, or
waiver of any provision of this Note or any other document or instrument
executed in connection herewith, or consent to any departure by Borrower
therefrom, shall in any event be effective without the written concurrence of
Lender.

         9. WAIVER OF JURY TRIAL. BORROWER AND LENDER ACKNOWLEDGE THAT THE RIGHT
TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. LENDER AND
BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE (AFTER CONSULTING
OR HAVING THE OPPORTUNITY TO CONSULT WITH COUNSEL OF THEIR CHOICE) ANY RIGHTS
THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER
RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF LENDER OR BORROWER. BORROWER
ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION
FOR THIS PROVISION AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR LENDER
TO MAKE THE LOAN EVIDENCED HEREBY.

         IN WITNESS WHEREOF, this Note is executed by Borrower as of the date
first written above.
