Agreement nor Customer's performance of its obligations hereunder conflicts with
or contravenes any other contract, agreement or instrument to which Customer or
its assets or property is bound.

entire agreement between the parties with respect to the subject matter hereof.
Any terms or conditions on any purchase order or other document that is

                                PRODUCT WARRANTY

B. Braun Medical Inc. ("B.Braun") warrants to and only to the original purchaser
or lessee ("Customer") of the Vista(TM) Basic Infusion Device ("Equipment") that
reasonable care has been used in the manufacture of each unit of Equipment and
that, when properly used and maintained by Customer, it shall be free from
defects in material and workmanship in accordance with its specifications for a
period of two (2) years from the date of shipment of such Equipment by B.Braun
("Warranty Period"). Any unit of Equipment that is found by B.Braun not to meet
these standards within this Warranty Period will, at B.Braun's sole option, be
repaired or replaced without charge. Any defective unit of Equipment or
component thereof should be returned promptly to B.Braun, properly packaged and
with postage prepaid by Customer. Customer shall provide labor for the removal
of defective Equipment and installation of its replacement, and shall bear all
risk of loss or damage while in transit. In the event no breach of warranty is
discovered by B.Braun upon receipt of any returned item, the item will be
returned to Customer at Customer's expense.

This Warranty is valid only if the Equipment is operated and maintained as
described in B.Braun's operator's manuals, supplements or other operating
instructions. This Warranty shall not apply to any Equipment or component
thereof if (1) any repairs, alterations, or other work has been performed on the
Equipment or any component thereof by anyone other than B.Braun or a technician
or repair facility authorized in writing by B.Braun; (2) the Equipment is
altered in any manner that, in B.Braun's sole judgement, affects its stability
or reliability; (3) the alleged condition or defect is a result of the misuse,
improper cleaning or improper handling, negligence, accident or improper
maintenance of any party; (4) the Equipment is not used in accordance with its
instructions for use furnished by B.Braun or is not used for its intended
purpose.

Any defect or condition that has been caused by the misuse, unauthorized
modification, or abnormal conditions of operation, or that is otherwise excluded
from this Warranty, will be repaired by B.Braun at its then current repair
charges. In this case, upon the request of Customer, B.Braun will submit an
estimate of the repair cost to Customer prior to making any repairs.

This Warranty does not extend to damages to, or resulting in whole or in part
from the use of, components, accessories, parts or supplies not supplied by
B.Braun for use with the Equipment. Products or components not manufactured by
B.Braun are not warranted by B.Braun, and Customer must rely on the warranties,
if any, provided directly be the manufacturer of such product or component.

EXCEPT AS EXPRESSLY PROVIDED HEREIN, B.BRAUN MAKES NO WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED BY OPERATION OF LAW OR OTHERWISE WITH RESPECT TO THE
EQUIPMENT INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. The sole and exclusive
remedy of Customer for breach by B.Braun of any warranty shall be limited, at
B.Braun's sole election, to the repair or replacement of the unit of Equipment
or any component thereof. In no event shall B.Braun be liable to Customer for
any indirect, incidental, special, consequential or punitive damages (including
damages for lost profits) arising out of or in connection with the delivery, use
or service of any Equipment or the performance, use or inability to use the
Equipment or otherwise, whether based in contract, warranty, tort (including
negligence) or any other legal or equitable theory.

B.Braun neither assumes, nor authorizes any person to assume for it, any
additional liability or responsibility in connection with the Equipment and no
agent, employee or representative of B.Braun has the right to modify or expand
the warranties set forth herein and no such modification or expansion should by
relied upon by Customer.

charges. In this case, upon the request of Customer, B.Braun will submit an
estimate of the repair cost to Customer prior to making any repairs.
