APPENDIX

TWELVE MONTH LIMITED WARRANTY

Leadshine Technology Co., Ltd. warrants its products against defects in materials
and workmanship for a period of 12 months from shipping date. During the warranty
period, Leadshine will either, at its option, repair or replace products which proved
to be defective.

EXCLUSIONS

The  above  warranty  shall  not  apply  to  defects  resulting  from:  improper  or
inadequate  handling  by  customer;  improper  or  inadequate  customer  wiring;
unauthorized  modification  or  misuse;  or  operation  beyond  the  electrical
specifications of the product and/or operation beyond environmental specifications
for the product.

OBTAINING WARRANTY SERVICE

To obtain warranty service, a returned material authorization number (RMA) must
be obtained from customer service at e-mail:

[email protected]

before returning

product for service. Customer shall prepay shipping charges for products returned to
Leadshine for warranty service, and Leadshine shall pay for return of products to
customer.

WARRANTY LIMITATIONS

Leadshine makes no other warranty, either expressed or implied, with respect to the
product. Leadshine specifically disclaims the implied warranties of merchantability
