                  (i) Initial production pricing shall be established within
                  [*] of completion of the pre-production units. Labor and
                  material costs determined from pre-production and the pricing

         D. Buyer may, without cost or liability, increase or decrease the
quantity specified in its Purchase Orders, within the following parameters:

            [*] Months         Firm PO's, May move up to [*] of scheduled
                               deliveries on PO's out 30 days without penalty,
                               or in 30 days depending on material
                               availability.

            [*] Months         May move up to [*] of scheduled deliveries on
                               PO's out 60 days without penalty, or in 60 days
                               depending on material availability.

            [*] Months         Delivery slides [*] will require an inventory
                               deposit.
</TABLE>

         E. Buyer shall use reasonable efforts to forecast it's intended
purchases on a rolling twelve (12) month basis. Contractor will use the 7-12
month forecast to procure long lead materials which may impact future deliveries
and to determine economic order quantity buys to reduce the recurring pricing to
the Buyer. Contractor will use its best effort to inform Buyer of a need to
authorize procurement of long lead materials beyond firm purchase orders to
protect Buyer's future demand.

         F.        EXCESS AND OBSOLETE MATERIALS

         (i) During the performance of this Agreement, Contractor will purchase
         materials to support the purchase requirements of the Buyers program.
         Certain materials which Contractor will acquire will be subject to
         minimum-buy requirements, scrap and attrition additions, and quantity
         price breaks which may result in excess material accumulation.
         Additionally, design changes may cause other materials to become
         obsolete.

         (ii) During the performance of this Agreement, Contractor will provide
         Buyer with periodic updates of the status and amount of excess or
         obsolete material.

         (iii) Contractor will use its best efforts to minimize the quantity and
         cost to Buyer of excess and/or obsolete materials relating to the
         production of Products, and whenever possible, return the same to
         Contractor's supplier or use the same in the manufacture of other
         Products for Buyer or other products for Contractor's other customers.
         Such effort will be coordinated with Buyer when possible. However,
         final costs associated with the

         so returned or used, shall be chargeable to and payable by Buyer in an
         amount equal to Contractor's cost plus material burden, but without
         profit. In no event shall Buyer be liable for any costs resulting from
         design changes, unless, prior to implementation of such changes,
         Contractor has advised Buyer in writing of the estimated amount of the
         costs. At Buyer's option, any excess and/or obsolete materials for
         which Buyer pays associated costs shall become the property of Buyer
         upon payment, and shall be held by Contractor, without further charge
         to Buyer, for disposition pursuant to Buyer's instructions within 90

damages, liability, costs and expenses (including, without limitation,
attorney's fees and legal costs and disbursements) incurred on account of any
injury to persons or property arising out of Contractor's negligence, reckless
conduct or willful misconduct relating to this Agreement, including but not
limited to (i) any failure of the contractor to manufacture the Product in
conformance with the Design Specifications, (ii) any failure by the Contractor
to comply with FDA GMP regulations, or (iii) the negligent manufacture of the
Product by the Contractor provided, that Contractor's liability hereunder shall
be reduced proportionately by the percentage of fault, if any, that may
ultimately be assigned or imposed on Buyer by a court of law or arbitrator as a
result of the Buyer's own negligence, reckless conduct or willful misconduct. In
the event any claim is asserted or any suit is filed against Buyer for which
Contractor is or may be required to indemnify Buyer under this provision, Buyer
shall give Contractor prompt written notice of same. In the event of any such
claim or suit against the Buyer, Buyer may at its option tender defense of the
claim or suit to Contractor, in which case the Buyer shall cooperate with
Contractor, at Contractor's request and expense, in the defense of such claim or
suit, and Contractor shall have the sole right to defend and/or settle such a
claim or suit, including selecting counsel of its choice. Regardless of whether
or not Buyer tenders defense of the claim or .suit to Contractor, and regardless
of whether or not Contractor chooses to accept or reject such tender, the
requirement of this paragraph that Contractor fully indemnify Buyer remains in
 .full force and effect.

         B. Buyer agrees to indemnify and hold Contractor, its affiliated
entities, and their respective officers, directors, shareholders, employees and
agents harmless from and against all claims, losses, damages, liability, cost
and expenses ( including, without limitation, attorneys' fees and legal costs
and disbursements) incurred on account of any injury to persons or property
arising out of the Buyer's negligence, reckless conduct or willful misconduct
relating to this agreement, including, with out limitation, (i) the negligent
design of any Product or (ii) furnishing incorrect or negligent design
specifications: provided, however, that this indemnity shall extend only to the
amount of claims, losses, damages, liability, costs and expenses not covered by
insurance under Section (c) hereinbelow.

         C. Buyer agrees to add and maintain Contractor as an additional insured
on Buyers product liability insurance policy. Contractor shall have the same
liability protection and coverage under the policy as Buyer. The policy shall
specifically waive any right of subrogation that the insurer may have against
the Contractor. Buyer shall provide Contractor with a certificate of insurance
verifying the foregoing provisions of this paragraph C.

XI.      FORCE MAJEURE

         Neither party shall be considered to be in default in respect of any
obligation hereunder, if failure of performance shall be due to Force Majeure.

than is required and the non-performing party shall use reasonable efforts to
remedy its inability to perform. Force Majeure shall mean, without limitation,
explosion, flood, fire, war (whether declared or otherwise), accident, labor
strike, or other labor disturbance, sabotage, acts of God, or acts of regulatory
