The warranty applicable to a product is as set out in the statement of
warranty policy (the "Warranty") above, receipt of which is hereby
acknowledged. The liability of tekmar is limited to those obligations
identified in the warranty as obligations of tekmar. The warranty is
understood to be in substitution for any loss, costs or damages for
which tekmar might otherwise be liable at law or in equity and in
particular, in lieu of any liability for fundamental breach of contract.
tekmar disclaims any responsibility for losses, expenses,
inconveniences, or any special, indirect, secondary, incidental or
consequential damages arising from ownership or use of any items
subject to any claim hereunder, regardless of whether such claim is
stated in contract, tort or strict product liability.
This warranty is in lieu of all other warranties, express or implied,
including, without limitation, warranties of merchantability, fitness for
a particular purpose, durability or description of the product, its non-
infringement of any relevant patents or trademarks, and its compliance
with or non-violation of any applicable environmental, health or safety
legislation. No implied warranties shall extend beyond twenty-four
(24) months from the production date.
Some states or provinces do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you. This warranty
gives you specific legal rights, and you may also have other rights which
vary from state to state or province to province.
