                                    AGREEMENT

     NOW, THEREFORE, for good and valuable consideration, and intending to be
legally bound, the parties hereby agree as follows:

1.   Definitions:

     1.1. "Inventory" shall mean the various kinds of inventory Company
customarily holds for sale to its end customers, which inventory shall include
among other things, Mobetron systems, surgical tables, accessories, and repair
parts.

     1.2. "Factored Inventory" shall mean Inventory and the related Receivable
for that Inventory.

     1.3. "Receivable" shall mean a purchase order or other contract for the
sale of Inventory to Company's end-user customer and all monies due thereunder.


2.   Terms and Conditions :

     2.1. Buyer will purchase up to $3,000,000 of combined Inventory and
Factored Inventory from Company, on a revolving basis, upon the terms and
conditions set forth herein:

     2.2. Buyer agrees to purchase, at the request of Company, Inventory as

     2.3. Buyer agrees to purchase, at the request of Company, Factored
Inventory as shown on Exhibit B attached hereto, as such may be updated from
time to time. The purchase price of Factored Inventory shall be eighty percent
(80%) of the face amount of the Receivable relating to such Factored Inventory.
To the extent that Company finds end-user customers for Inventory already sold
to Buyer and Buyer requests that such Inventory be considered Factored
Inventory, Buyer agrees to remit to Company the difference between (a) eighty
percent (80%) of the amount of the Receivable due for such Factored Inventory
and (b) the amount already paid to Company pursuant to the sale of that
Inventory to Buyer.

     2.4. Upon the sale of Inventory to Buyer, Company will execute and deliver
to Buyer:

     (a)  A Bill of Sale for such Inventory in substantially the form of Exhibit
          C attached hereto;
     (b)  Copies of all invoices relating to the Inventory; and
     (c)  Copies of checks or other  forms of proof of payment  relating  to the
          Inventory.

     2.5. Upon sale of Factored Inventory to Buyer, Company will execute and
deliver to Buyer:

     (a)  A Bill of Sale and Assignment of Receivables in substantially the form
          of Exhibit D hereto;
     (b)  Copies  of  the  purchase  order  or  other  contract  comprising  the
          Receivable;
     (c)  Copies of all invoices relating to the Inventory; and
     (d)  Copies of checks or other  forms of proof of payment  relating  to the
          Inventory.

     2.6. Company hereby acknowledges and agrees that Buyer may file one or more
UCC financing statements in appropriate jurisdictions as notice of it ownership
interest in the Inventory and Factored Inventory.

     2.7. Inventory and Factored Inventory purchased by Buyer will be stored
free-of-charge to Buyer by Company at such locations as Company customarily
warehouses its own inventory and Company will provide for the same care,
safekeeping, and insurance of Buyer's Inventory as Company customarily keeps for
its own Inventory, provided however, that Company will not be required to insure
or provide any other form of surety for Receivables related to Factored
Inventory.

     2.8. Buyer covenants not to sell, dispose of, pledge, grant an interest in,
or otherwise encumber Inventory or Factored Inventory that Buyer purchases from
Company, and agrees to hold such Inventory and Factored Inventory free and clear
of all liens and encumbrances for later repurchase by Company.

of each month.

     2.10. Company agrees to pay interest to Buyer on the outstanding balance of
Factored Inventory purchased by Buyer at the rate of twenty-four percent (24%)
per annum, compounded monthly, such interest to be paid from the proceeds from
the liquidation of the Receivable as and when paid by the Receivable
counterparty.

     2.11. Company agrees to notify and request that all payments received
relating to Factored Inventory be remitted by wire directly to Buyer at the wire
address shown on Exhibit E hereto. To the extent that Company receives any
monies from its customers related to Factored Inventory prior to repurchase or
repayment of all outstanding sums due Buyer for that same Factored Inventory,
Company will immediately remit to Buyer the lesser of the (a) amount received by
Company or (b) the amount required to complete the repurchase of the Factored
Inventory from Buyer, including any interest thereon.

     2.12. To the extent Buyer receives payments for Inventory or Factored
Inventory in excess of the amounts required for the Company to repurchase such
Inventory or Factored Inventory, and unless otherwise directed by Company to
apply such sums to the repurchase of other Inventory or Factored Inventory,
Buyer will immediately remit such sums to Company at the wire address set forth
in Exhibit F.

     2.13. From time to time, Company may repurchase Inventory and Factored
Inventory from Buyer. The repurchase price of Inventory and Factored Inventory
shall be the same price that Buyer paid to Company for such Inventory or
Factored Inventory, plus any outstanding and unpaid interest thereon net of any
prior payments received by Buyer from Company or otherwise.

     2.14. Upon repurchase of Inventory, Buyer will execute a Bill of Sale in
substantially the form of Exhibit C hereto and, to the extent applicable, will
also execute UCC termination statements as requested by Company to evidence
Buyer's release of its ownership interest in such Inventory. Upon repurchase of

Receivables in substantially the form of Exhibit D hereto and, to the extent
applicable, will also execute UCC termination statements as requested by Company

     2.15. To the extent that orders for its products can be satisfied from
Inventory purchased by Buyer, Company agrees to preferentially fill such orders
through the repurchase of such Inventory from Buyer.
