stock dividend, split-up, combination, reclassification, exchange, merger,
consolidation or otherwise, change its shares of common stock into a different
number or kind or class of shares or other securities or property, then the
number of shares covered by this Option, and the price of each such share shall
be proportionately adjusted for any such change. If there is any dispute as to
the proper adjustment, so long as the Board of Directors of Valesc determination
is not unreasonable, such determination shall be conclusive as to Subscriber.

          by the Company (Addendum 2) all orders for PRODUCTS in the TERRITORY.
          Such orders may be accepted or rejected by the Company at its sole

               Representative to offset said charges in the next month, the
               charges will be billed to the Representative. Or upon termination
               of this Agreement, the Representative shall pay said charges to
               company upon presentation.

                             CONSIGNMENT AGREEMENT

Agreement made between ACUMED, INC. (hereafter called Supplier) and MEDEX
SURGICAL (hereafter called Representative) this 16TH DAY OF MARCH, 1999. The
purpose of this agreement is to provide an inventory of the most current Acumed
implants and instruments (Products) presently available, as well as insure the
immediate availability of new designs as they evolve. Consequently, the
inventory levels maintained by the Representative will remain consistent with
the Customer demand for this service. Finally, the arrangements described herein
will release the Representative of the financial burden incurred by purchasing
and maintaining a complete stock of the above products.

NOW, THEREFORE, intending to be legally bound, the parties agree as follows:

1. ESTABLISHMENT OF PROGRAM

     a.   Supplier will establish a consignment inventory program for standby
          implants and instruments for use by the Representative for its
          Customers. Instruments will be provided on consignment as detailed in
          ADDENDUM 5.

     b.   Representative will provide a secure area within its facility for the
          storage of consignment inventory separate from Representative's owned
          inventory.

     c.   Appropriate inventory levels will be determined by the joint agreement
          of Supplier and Representative.

     d.   The initial consignment inventory shall be shipped on a consignment
          no-charge purchase order. Any subsequent additions to the consignment
          inventory will be communicated by written correspondence including
          quantities, catalogue numbers and product descriptions. Any changes to
          consignment levels of product will be similarly communicated and
          acknowledged by the Representative and Supplier.

     e.   Representative shall be responsible for physical inventories of lot
          coded items on a quarterly basis. Supplier reserves the right to delay
          commission payments if the inventory is not received and reconciled by
          the 15th of the month.

     f.   Supplier will either replenish inventory used in surgery automatically
          upon the receipt of a completed order form or require that
          Representative replenish its inventory of Product on an as needed
          basis to maintain adequate stocking levels. A Customer purchase order
          is required WITHIN THREE DAYS OF IMPLANTING Supplier's products.
          Invoices will be issued and payments due in accordance with Supplier's
          published regular terms.

     g.   Items for which a hospital purchase order is issued will either be
          shipped from Supplier to Representative's designated receiving or
          directly to the hospital if so specified by Representative.

     h.   The hospital purchase order will clearly indicate that the products
          are for CONSIGNMENT REPLACEMENT and the Supplier will print
          CONSIGNMENT REPLACEMENT on the appropriate shipping and invoicing
          documents.

     i.   The Representative agrees that this consignment inventory is the
          property of Supplier and that the Supplier or the Supplier's
          representative will have free access (with appropriate prior notice
          and approval) to this inventory.

     j.   The Representative agrees to pay for any unutilized consignment
          inventory which has been opened and is not implantable WITHIN THREE
          DAYS OF OPENING. All consignment inventory opened but reusable will be
          repackaged by Supplier. There will be a 25% charge for this service.

                                       10

     k.   The parties agree that the Representative will be responsible for
          inventory losses due to loss, theft, damage or otherwise not accounted
          for during routine audits at current distributor price list value.

     l.   The Supplier agrees to inform the Representative of any
          manufacturing/packaging changes that will affect the consignment.

2.   This agreement shall be effective for the period of the MANUFACTURER'S
     REPRESENTATIVE AGREEMENT and will be renewed in accordance with the dates
     of the MANUFACTURER'S REPRESENTATIVE AGREEMENT.

                            NON-DISCLOSURE AGREEMENT

This non-disclosure agreement (the "AGREEMENT") is entered into this 16TH DAY OF
MARCH, 1999 by ACUMED, INC. (the "DISCLOSING PARTY") and MEDEX SURGICAL, its
PRINCIPALS, MANAGEMENT and STAFF (the "RECEIVING PARTY") for the purpose of
preventing the unauthorized disclosure of Confidential Information (as defined
below) of the Disclosing Party which may be disclosed to the Receiving Party for
the purpose of pursuing the establishment of a business relationship or
negotiating any contract or agreement between the Disclosing Party and the
Receiving Party.

For purposes of the agreement, Confidential Information shall mean any and all
information relating to Acumed Products and Pricing.

In consideration of the Disclosing Party's disclosure of Confidential
Information to the Receiving Party, the Receiving Party hereby agrees as
follows:

1.   The Receiving Party shall hold and maintain the Confidential Information in
     strictest confidence and in trust for the sole and exclusive benefit of the
     Disclosing party.

2.   The Receiving Party shall not, without the prior written approval of the
     Disclosing Party, use for its own benefit, publish or otherwise disclose to
     others, or permit the use by others for their benefit or to the detriment
     of the Disclosing party, any of the Confidential Information.

3.   The Receiving Party shall carefully restrict access to the Confidential
     Information to those of its officers, directors and employees who clearly
     need such access in order to participate on the behalf of the Receiving
     Party in the analysis and negotiation of a business relationship or any
     contract or agreement, or the advisability thereof, with the Disclosing
     Party. The Receiving Party further warrants and represents that it will
     advise each of the persons to whom it provides access to any of the
     Confidential Information pursuant to the foregoing sentence that such
     persons are strictly prohibited from making use, publishing or otherwise
     disclosing to others or permitting others to use for their benefit or to
     the detriment of the Disclosing Party, any of the Confidential Information.

4.   The Receiving Party shall take actions necessary to protect the
     confidentiality of the Confidental Information except for its disclosure
     pursuant to paragraph 3 above, and hereby indemnifies the Disclosing Party
     against any and all losses, damages, claims or expenses incurred or
     suffered by the Disclosing Party as a result of the Receiving Party's
     breach of this Agreement.

5.   This agreement shall continue in full force and effect indefinitely, except
     that the Receiving Party's obligations hereunder shall not extend to any of
     the Confidential Information which the Receiving Party can demonstrate was
     in the public domain on the date of this Agreement.

6.   The Receiving Party understands and acknowledges that any disclosure or
     misappropriation of any of the Confidential Information in violation of
     this Agreement may cause the disclosing Party irreparable harm, the amount
     of which may be difficult to ascertain and, therefore, agrees that the
     Disclosing Party shall have the right to apply to a court of competent
     jurisdiction for an order restraining any such further disclosure or
     misappropriation and for such other relief as the Disclosing Party shall
     deem appropriate, such right of the Disclosing Party to be in addition to
     the remedies otherwise available to the Disclosing Party at law or in
     equity.

7.   The Receiving Party shall return to the Disclosing Party any and all
     records, notes and other written, printed or tangible materials pertaining
     to the Confidential Information immediately upon written request of the
     Disclosing Party.

8.   This Agreement and the Receiving Party's obligations hereunder shall be
     binding upon the representatives, assigns and successors of the Receiving
     Party and shall inure to the benefit of the assigns and successors of the
     Disclosing Party.

9.   The Agreement shall be governed by and construed in accordance with
     internal laws of the State of Oregon.

10.  If any action at law or inequity is brought to enforce or interpret the
     provisions of this Agreement, the prevailing party in such action shall be
     entitled to reasonable attorney's fees.

11.  The Agreement constitutes the sole understanding of the parties with
     respect to the subject matter hereof and may not be amended or modified
     except in writing signed by each of the parties hereto.
