Limited Warranty and Product Return Procedure
Limited Warranty The liability of tekmar under this warranty is lim-
ited. The Purchaser, by taking receipt of any tekmar product ("Prod-
uct"), acknowledges the terms of the Limited Warranty in effect at
the time of such Product sale & acknowledges that it has read &
understands same.
The tekmar Limited Warranty to the Purchaser on the Products sold
hereunder is a manufacturer's pass-through warranty which the Pur-
chaser is authorized to pass through to its customers. Under the
Limited Warranty, each tekmar Product is warranted against defects
in workmanship & materials if the Product is installed & used in com-
pliance with tekmar's instructions, ordinary wear & tear excepted.
The pass-through warranty period is for a period of twenty-four
(24) months from the production date if the Product is not installed
during that period, or twelve (12) months from the documented date
of installation if installed within twenty-four (24) months from the pro-
duction date.
The liability of tekmar under the Limited Warranty shall be limited to, at
tekmar's sole discretion: the cost of parts & labor provided by tekmar to
repair defects in materials &/or workmanship of the defective product;
or to the exchange of the defective product for a warranty replacement
product; or to the granting of credit limited to the original cost of the defec-
tive product, & such repair, exchange or credit shall be the sole remedy
available from tekmar, &, without limiting the foregoing in any way, tekmar
is not responsible, in contract, tort or strict product liability, for any other
losses, costs, expenses, inconveniences, or damages, whether direct,
indirect, special, secondary, incidental or consequential, arising from
ownership or use of the product, or from defects in workmanship or mate-
rials, including any liability for fundamental breach of contract.
The pass-through Limited Warranty applies only to those defective Prod-
ucts returned to tekmar during the warranty period. This Limited War-
ranty does not cover the cost of the parts or labor to remove or transport
the defective Product, or to reinstall the repaired or replacement Product,
all such costs & expenses being subject to Purchaser's agreement &
warranty with its customers.

Purchaser's customers, regarding a potential warranty claim, tekmar's
sole obligation shall be to provide the address & other contact informa-
tion regarding the appropriate Representative.
