third party without an obligation of confidentiality to Manufacturer, (iv) is
disclosed to a third party by Manufacturer without restriction; or (v) is

<PAGE>

that the equipment will be free from defects in material and workmanship under
normal use and service. Manufacturer's sole obligation under this Warranty is
limited to replacing or repairing, at its option, at its factory, any equipment
which is returned to Manufacturer, transportation, duties, and taxes prepaid, *.
In the case of Equipment not of Manufacturers own manufacture, the warranty
under the terms of this Paragraph is available only for a period of one (1) year
after delivery. Manufacturer shall return the equipment to Distributor freight
prepaid. THIS WARRANTY IS EXPRESSED IN LIEU OF ALL OTHER WARRANTIES, EXPRESS,
IMPLIED OR STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE, AND OF ALL OTHER OBLIGATIONS OR LIABILITIES ON
THE PART OF MANUFACTURER AND IT NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON
TO ASSUME FOR MANUFACTURER ANY OTHER LIABILITIES IN CONNECTION WITH THE SALE OF
EQUIPMENT. IN NO EVENT WILL MANUFACTURER BE LIABLE FOR CONSEQUENTIAL DAMAGES
EVEN IF MANUFACTURER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. This
Warranty does not apply to any of such Equipment which shall have been repaired
or altered, except by Manufacturer, or which shall have been subjected to
misuse, negligence, or accident or operation outside the environmental
specifications. Repairs or replacements of Equipment made during the warranty
period or thereafter will be warranted, as provided above, for the remainder of
the original warranty period or for ninety days from the date of return, as
applicable, whichever is longer.

11.0    PATENT INFRINGEMENT. Manufacturer will defend any action, including a
claim or suit, against Distributor claiming that Products infringe any patent,
and will pay all costs and damages finally awarded in any such action, provided
that Manufacturer is notified promptly in writing of the action and at
Manufacturer's request and at its expense is given control of such action and
all requested information and assistance to settle or defend the same. Should
use of Products be enjoined as a result of such action, then Manufacturer shall
in a reasonable time either: (a) obtain for Distributor the right to continue to
use the Products; (b) modify or replace the Products with noninfringing
Products; or (c) request the return of the Products and upon their return refund
the value of the Products as amortized over a presumed five (5) year
depreciation period, as well as transportation costs. Manufacturer shall have no
obligation to defend any claims arising out of combinations of the Products when
used in combination with other products not supplied by Manufacturer. THE
FOREGOING STATES THE SOLE AND EXCLUSIVE LIABILITY OF MANUFACTURER FOR PATENT
INFRINGEMENT AND IS IN LIEU OF ANY OTHER WARRANTY AGAINST INFRINGEMENT OF ANY
KIND, EXPRESS, IMPLIED, OR STATUTORY.

12.0    DAMAGE LIMITATION. INDEPENDENTLY OF ANY OTHER LIMITATION HEREOF AND
REGARDLESS OF WHETHER THE PURPOSE OF ANY REMEDY SET FORTH HEREIN IS SERVED, IT
IS AGREED THAT IN NO EVENT SHALL MANUFACTURER BE LIABLE FOR SPECIAL, INCIDENTAL
OR CONSEQUENTIAL DAMAGES OF ANY KIND UNDER THIS AGREEMENT.
