Limited Warranty

A. Warranty - Minarik Corporation (referred to as “the Corporation”) warrants that its
products will be free from defects in workmanship and material for two (2) years from date
of shipment thereof, or 6,000 hours, whichever comes first. Within this warranty period, the
Corporation will repair or replace such products that are: (1) returned to Minarik Corporation,
901 East Thompson Avenue, Glendale, CA 91201-2011 U.S.A.; and, (2) determined by the
Corporation to be defective.

This warranty shall not apply to any product that has been subject to misuse, negligence, or
accident; or misapplied; or repaired by unauthorized persons; or improperly installed. The
Corporation is not responsible for removal, installation, or any other incidental expenses
incurred in shipping the product to and from the repair point.

B. Disclaimer - The provisions of Paragraph A are the Corporation’s sole obligation and
exclude all other warranties of merchantability for use, express or implied. The Corporation
further disclaims any responsibility whatsoever to the customer or to any other person for
injury to the person or damage or loss of property of value caused by any product that has
been subject to misuse, negligence, or accident, or misapplied or modified by unauthorized
persons or improperly installed.

C. Limitations of Liability - In the event of any claim for breech of any of the Corporation’s
obligations, whether express or implied, and particularly of any other claim or breech of
warranty contained in Paragraph A, or of any other warranties, express or implied, or claim
of liability that might, despite Paragraph B, be decided against the Corporation by lawful
authority, the Corporation shall under no circumstances be liable for any consequential
damages, losses, or expense arising in connection with the use of, or inability to use, the
Corporation’s product for any purpose whatsoever.

An adjustment made under warranty does not void the warranty, nor does it imply an
extension of the original two (2) year or 6,000 hour warranty period. Products serviced
and/or parts replaced on a no-charge basis during the warranty period carry the unexpired
portion of the original warranty only.

If for any reason any of the foregoing provisions shall be ineffective, the Corporation’s
liability for damages arising out of its manufacture or sale of equipment, or use thereof,
whether such liability is based on warranty, contract, negligence, strict liability in tort, or
otherwise, shall not in any event exceed the full purchase price of such equipment.

Any action against the Corporation based upon any liability or obligation arising hereunder
or under any law applicable to the sale of equipment or the use thereof, must be
commenced within one year after the cause of such action arises.
