5.   DURATION

5.1  Subject to Clause 12 below, this Agreement shall commence on the Effective
     Date and shall continue for an initial period expiring on the third
     anniversary after the Effective Date ("the Initial Term").

5.2  Six months before the conclusion of the "the Initial Term" subject to
     Clause 12 below both parties agree to formally review this Agreement and
     its implementation in light of the two and a half years of experience
     gained and to prepare a revised Agreement for a second three year period
     ("the Second Term"). Although the terms of this revised Agreement are to be
     decided at the time it is prepared it shall include the provision for a
     continuation of USMS "Exclusive Distribution" rights in the "Wound Care
     Market" and non-exclusive marketing rights in all other applicable medical
     fields for the Scanner in the Territory. If the parties have not signed an
     Agreement covering the "Second Term" by the end of "the Initial Term" then
     both parties agree to immediately refer the matter to the binding
     arbitration of the AAA as described in Clause 9.3, excepting that all
     arbitration costs shall be divided equally between Longport and USMS under
     these circumstances. During the arbitration process the terms of this
     Agreement shall continue.

6.   SUPPLY

6.1  Subject to Clause 7.6 below and Condition 14 (Force Majeure) of the Terms
     and Conditions, Longport shall use all reasonable endeavors to supply the
     Scanner to USMS in accordance with each Order placed by USMS.

6.2  Longport shall be entitled at any time or from time to time to make such
     modifications to the specification of the Scanner as it may in its sole
     discretion think fit. Whenever possible Longport will review any change in
     specification with USMS before they are implemented.

6.3  USMS shall in respect of each Order for the Scanner to be supplied
     hereunder be responsible for:

     (a)  ensuring the accuracy of the Order;

                                       9                            CONFIDENTIAL

CONFIDENTIAL

     (b)  providing Longport with any information which is reasonably necessary
          in order to enable Longport to fulfill the Order;

6.4  Upon receipt and confirmation of each Order Longport shall, as soon as is
     reasonably practicable, inform USMS of Longport's estimated delivery date
     for the order. Longport shall use all reasonable endeavors to meet the
     delivery date, normally four months after receipt of order, but time of
     delivery shall not be of the essence and accordingly Longport shall have no
     liability to USMS if, notwithstanding such endeavors, there is any delay in
     delivery. Longport shall however advise USMS of any expected delivery
     delays at the earliest practical opportunity.

     However, if Longport has been unable to deliver products ordered in
     accordance with this Agreement 120 days after the due date for that order
     has passed then USMS shall have the right to have the Scanner manufactured
     by their own sources and Longport shall provide all necessary licenses
     required for this production. This manufacturing right shall only cover
     Scanners that USMS requires for their distribution needs as described in
     this Agreement.

     In circumstances where Longport is found to have defaulted as described in
     the above paragraph arbitration should be sought as described in Clause
     10.3 to determine how the deposit outstanding, initially $500,000, is
     repaid and if this repayment should be made in cash or in components
     already in the production pipeline or some combination of the two.

6.5  Longport shall be exclusively responsible for the first 12 months of this
     Agreement for the training and support of end user customers contracted to
     USMS or any of USMS's sub-agents and USMS shall not seek such customer
     support from any other party. If after the first 12 months of this
     Agreement has concluded USMS or one of its sub-agents wishes to train and
     support their customers directly they shall be entitled so to do, provided
     they give 6 months notice to Longport.

     If USMS or any of your sub-agents wish to undertake the training and
     support responsibility they shall submit to Longport for approval all
     training and support documentation and procedures. All such programs and
     documentation shall be subject to approval by Longport and Longport will on
     an on-going basis be exclusively responsibly for accrediting all Scanner
     related training and support programs and the personnel involved.

     Longport will have the right not to accredit any program or person, and
     neither USMS nor its sub-agents shall use any non-accredited program or
     person in any training or support capacity with regard to the Scanner. Fees
     will be charged for these accreditation services by Longport.

     If during the first 18 months of this Agreement any end-user customer of
     USMS requiring multiple Scanners, greater than 20, wishes to develop and
     use an in-house training program Longport and USMS shall work with that

     customer to develop an appropriate training program. Longport shall charge
     for its input into this program development.

     Details of Longport's standard end user support provision are presented in
     a Schedule 3 of this Agreement

6.6  The terms of this Agreement, which includes the Schedules attached hereto,
     shall apply to the exclusion of any other terms and conditions including
     any implied by trade, custom, practice or course of dealing. Purported
     provisions to the contrary are excluded.

7.   PAYMENTS

7.1  On signature of this Agreement USMS shall provide Longport with an initial
     order for 100 scanners and within 5 business days of signature of this
     Agreement Longport shall receive from USMS a deposit of $500,000 by wire
     transfer on these first 100 scanners. Longport shall immediately notify
     USMS of the receipt of this transfer.

7.2  This Agreement shall not be considered consummated until the payment
     described in 7.1 is received by Longport. If Longport does not receive the
     payment described in Clause 7.1 within 5 business days of signature of this
     Agreement, this Agreement will automatically be null and void.

                                       11                           CONFIDENTIAL

7.3  Between the time of signature of this Agreement and the day that the
     deposit of the $500,000 is received by Longport, no press release or
     announcement shall be made by either part in regard to this Agreement.
     Further, if any party believes that the other party, any company, sub-agent
     or any individual associated with that party has directly or indirectly
     gained or tried to gain any benefit from the existence of this Agreement
     before it has been announced to the public at large this Agreement can be
     made null and void, subject to Clause 9.3. During this five-day period both
     parties shall develop a joint press release to be issued the day the
     payment is received by Longport.

7.4  USMS shall place firm orders for units four months in advance of the
     required delivery. At the time each order is placed a 20% deposit shall be
     placed. USMS shall take physical delivery of all products ordered within
     the month delivery is due and pay the outstanding purchase price within
     fifteen business days of delivery. For the avoidance of doubt a second
     order shall be placed by USMS with Longport not less than 30 days after the
     first shipment is made.

7.5  The initial purchase price for the scanner shall be $22,000 per unit. This
     price shall include "System Training" and "Customer Support" as defined,
     but exclude any applicable taxes and duties. Additional costs associated
     with specific "Application Training" and support as well as component costs
     are defined in Schedule 3 of this Agreement. Provided USMS abides with all
     terms of this Agreement Longport shall not offer the same package provision
     (Scanner plus training plus user support as described in this document) at
     a lesser cost as to that being charged to USMS (at that time) to any other
     customer in the Territory for the duration of this Agreement.

7.6  Longport has the right to change the purchase price for the scanner given
     60 days notice, but will provide a written explanation as to why any price
     change has been made. Such price changes will be applied across the board
     to all customers of that device or service provision, including pro rata to
     any direct customers Longport may have. If USMS believe that any price
     change made is not justified then they will have the right to seek an
     arbitration ruling as outlined in Clause 9.3.

7.7  For the duration of this Agreement, Longport shall pay to USMS 1% of its
     Scanner sale receipts from the US "Wound Care Market" that arise from
     either direct sales made by Longport or those undertaken to other third

     party agents or distributors. (Other third party agents or distributors
     exclude USMS and all of its sub-agents.) This obligation shall start from
     the date USMS gains its "exclusivity" into in the US "Wound Care Market".
     These payments are subject to USMS continuing to meet all its obligations

          and has established viable distribution channels.

          administrator or administrative receiver or other officially appointed
          officer or manager is appointed to the whole or any part of its assets
          or undertaking or circumstances arise which entitle the Court or a
          creditor to appoint a receiver or manager or administrator or
          administrative receiver or other official officer or manager or which
          entitle the Court to make a winding-up order or if USMS takes or

          entity then Longport can insist that USMS or that sub-agent correct
          the damaging action or potential damaging action within fifteen

          corrective action does not occur to Longport's satisfaction then USMS

     or part of an Order so cancelled and, with regard to any uncancelled part

     party may by written notice require the other party to resolve the dispute
     by negotiation in good faith. Where such a notice is given, each party
     shall use their best endeavors to resolve the dispute. In the event that

     The Price is calculated on a free carrier basis (as set out in ICC
     Incoterms 2000) and includes the cost of packaging, carriage and insurance
     to the time at which any Scanner is delivered to the carrier for carriage
     to USMS but excludes all costs thereafter.

5.2  Change in Rates of Insurance and Transit Charges

     The Price is based on current rates of insurance and other transit charges
     and for the normal route for carriage. Any increase in these charges or
     variation in such route shall entitle Longport to increase the Price for
     the Scanner by a corresponding sum.

5.3  Delay or Failure in Making Payment

     If USMS fails to pay the price for any Scanner within 15 Business Days
     after the date of the relevant invoice, Longport shall be entitled (without
     prejudice to any other right or remedy it may have) to :

     (a)  cancel or suspend any further delivery to USMS under any Order; and

     (b)  charge USMS interest on the price at the rate of 4 per cent. per annum
          above US base rate in force from time to time from the date the
          payment became due until actual payment in full is made. Any interest
          so accrued shall be separately invoiced by Longport and paid by USMS
          with 15 business days after the date of the relevant invoice,
          non-payment of any such invoice shall be treated in the same manner as
          a Scanner related invoice.

5.4  All payments shall be made by USMS in US Dollars to such bank account as
     Longport may from time to time notify in writing to USMS.

     delivery of the goods to the carrier of other third party nominated by
     USMS.

8.   Product Warranty

     The Scanner, excepting the probe, will be supplied with a one-year limited
     warranty provided by Longport. If during that period the Scanner develops a
     fault the unit so affected will be repaired or replaced, at Longport's
     discretion, free of charge. This provision does not include Scanners that
     have been incorrectly used or otherwise damaged by the user or other party.
     The probe will be provided with a three month limited warranty under the
     same terms.

     Units requiring repair under warranty shall be returned to a Longport's
     facility. End users shall advise Longport of any fault by phone, e-mail,
     fax or through Longport's WEB site and if the reported problem cannot be
     corrected by simple remedial actions (e.g. confirming connecting power
     cords have not come loose, power is being provided from the wall socket,
     system software is being used and interpreted correctly etc), which will be
     undertaken in conjunction with phone and or e-mail communications, the unit
     or component will be collected by Longport or an agent of Longport for
     repair or replacement. If the unit cannot be repaired or replaced within
     four business days Longport will provide a loan system, unit the original
     unit is either repaired or permanently replaced.

     No unit shall be returned to Longport without the end-user first obtaining
     a return reference from Longport. If a unit is returned without the end
     user first obtaining a return reference Longport shall automatically level
     an administration charge as defined in Schedule 3.

                                       27                           CONFIDENTIAL

CONFIDENTIAL

     If a unit is returned to Longport and is found to have no fault or one that
     simple remedial action as illustrated above would have solved, then
     Longport will have a right to charge a set fee administration as defined in
     Schedule 3 plus obtain reimbursement for shipping fees incurred.

9.   PRODUCT UPDATES

     Longport shall offer to USMS and or its subagents all appropriate product

     following product purchase.

10.  SELLER'S RESERVATION

(b)  If USMS, one of its sub-agents or any end user wishes to supply their own
UPS to operate with the Scanner they must advise Longport of the unit they
intend to use and obtain written approval from Longport on the suitability of
that unit. Failure to do this could invalidate the Scanner warranty and negate
Longport's product liability responsibility.

course. The cost of the course will be $2,500 per facility (five people
attending course). If travel beyond a 175mile radius of Longport's office(s) is

the course is undertaken within 50 miles of Longport's office the fee will be
reduced to $2,000.

run for staff members that joined subsequent to the system training or could not
attend for other reasons. These courses will be run at single venues every few
months.
