The Seller warrants that the standard hardware products sold will be free from defects in material and work-
manship and perform to the Seller’s applicable published specifications for a period of 18 months for hardware,
and 3 months for software, from the date of the original invoice. The liability of the Seller hereunder shall be
limited to replacing or repairing, at its option, any defective products which are returned F.O.B. to the Seller’s
plant, (or, at the Seller’s option, refunding the purchase price of such products). In no case are products to be
returned without first obtaining permission and a customer return authorization number from the Seller. In
no event shall the Seller be liable for any consequential or incidental damages.

Equipment or parts which have been subject to abuse, misuse, accident, alteration, neglect, unauthorized
repair or installation are not covered by warranty. The Seller shall make the final determination as to the
existence and cause of any alleged defect. No warranty is made with respect to custom equipment or products
produced to the Buyer’s specifications except as specifically stated in writing by the Seller in the contract for
such custom equipment.

This warranty is the only warranty made by the Seller with respect to the goods delivered hereunder, and may
be modified or amended only by a written instrument signed by a duly authorized officer of the Seller and
accepted by the Buyer.

Warranty and remedies on products not manufactured by the Seller are in accordance with warranty of the
respective manufacturer. THE SELLER MAKES NO OTHER WARRANTY OF ANY KIND WHATSOEVER,
EXPRESSED OR IMPLIED; AND ALL IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PUR-
POSE WHICH EXCEEDS THE AFORESAID OBLIGATIONS IS HEREBY DISCLAIMED BY THE SELLER.
