SUMMARY OF WARRANTY

The Crown Audio Division of Crown International, Inc., 1718 West Mishawaka Road,
Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL PURCHASER and
ANY SUBSEQUENT OWNER of each NEW Crown product, for a period of three (3)
years from the date of purchase by the original purchaser (the “warranty period”) that
the new Crown product is free of defects in materials and workmanship. We further
warrant the new Crown product regardless of the reason for failure, except as excluded
in this Warranty.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred
within the Warranty Period. It does not cover any product which has been damaged
because of any intentional misuse, accident, negligence, or loss which is covered
under any of your insurance contracts. This Crown Warranty also does not extend to
the new Crown product if the serial number has been defaced, altered, or removed.

WHAT THE WARRANTOR WILL DO

We will remedy any defect, regardless of the reason for failure (except as excluded),
by repair, replacement, or refund. We may not elect refund unless you agree, or unless
we are unable to provide replacement, and repair is not practical or cannot be timely
made. If a refund is elected, then you must make the defective or malfunctioning
product available to us free and clear of all liens or other encumbrances. The refund
will be equal to the actual purchase price, not including interest, insurance, closing
costs, and other finance charges less a reasonable depreciation on the product from
the date of original purchase. Warranty work can only be performed at our authorized
service centers or at the factory. We will remedy the defect and ship the product from
the service center or our factory within a reasonable time after receipt of the defective
product at our authorized service center or our factory. All expenses in remedying the
defect, including surface shipping costs in the United States, will be borne by us. (You
must bear the expense of shipping the product between any foreign country and the
port of entry in the United States and all taxes, duties, and other customs fees for such
foreign shipments.)

HOW TO OBTAIN WARRANTY SERVICE

You must notify us of your need for warranty service not later than ninety (90) days after
expiration of the warranty period. All components must be shipped in a factory pack,
which, if needed, may be obtained from us free of charge. Corrective action will be
taken within a reasonable time of the date of receipt of the defective product by us or
our authorized service center. If the repairs made by us or our authorized service
center are not satisfactory, notify us or our authorized service center immediately.
