Warranty and Limitation of Liability.  PNI Sensor Corporation ("PNI") manufactures its V2Xe products 
(“Products”) from parts and components that are new or equivalent to new in performance.  PNI warrants that each 
Product to be delivered hereunder, if properly used, will, for one year following the date of shipment unless a 
different warranty time period for such Product is specified: (i) in PNI’s Price List in effect at time of order 
acceptance; or (ii) on PNI’s web site (www.pnicorp.com) at time of order acceptance, be free from defects in 
material and workmanship and will operate in accordance with PNI’s published specifications and documentation 
for the Product in effect at time of order.  PNI will make no changes to the specifications or manufacturing processes 
that affect form, fit, or function of the Product without written notice to the OEM, however, PNI may at any time, 
without such notice, make minor changes to specifications or manufacturing processes that do not affect the form, 
fit, or function of the Product.  This warranty will be void if the Products’ serial number, or other identification 
marks have been defaced, damaged, or removed.  This warranty does not cover wear and tear due to normal use, or 
damage to the Product as the result of improper usage, neglect of care, alteration, accident, or unauthorized repair. 

THE ABOVE WARRANTY IS IN LIEU OF ANY OTHER WARRANTY, WHETHER EXPRESS, IMPLIED, OR 
STATUTORY, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF MERCHANTABILITY, 
FITNESS FOR ANY PARTICULAR PURPOSE, OR ANY WARRANTY OTHERWISE ARISING OUT OF ANY 
PROPOSAL, SPECIFICATION, OR SAMPLE.  PNI NEITHER ASSUMES NOR AUTHORIZES ANY PERSON 
TO ASSUME FOR IT ANY OTHER LIABILITY. 

If any Product furnished hereunder fails to conform to the above warranty, OEM’s sole and exclusive remedy and 
PNI’s sole and exclusive liability will be, at PNI’s option, to repair, replace, or credit OEM’s account with an 
amount equal to the price paid for any such Product which fails during the applicable warranty period provided that 
(i) OEM promptly notifies PNI in writing that such Product is defective and furnishes an explanation of the 
deficiency; (ii) such Product is returned to PNI’s service facility at OEM’s risk and expense; and (iii) PNI is satisfied 
that claimed deficiencies exist and were not caused by accident, misuse, neglect, alteration, repair, improper 
installation, or improper testing.  If a Product is defective, transportation charges for the return of the Product to 
OEM within the United States and Canada will be paid by PNI.  For all other locations, the warranty excludes all 
costs of shipping, customs clearance, and other related charges.  PNI will have a reasonable time to make repairs or 
to replace the Product or to credit OEM’s account.  PNI warrants any such repaired or replacement Product to be 
free from defects in material and workmanship on the same terms as the Product originally purchased. 

Except for the breach of warranty remedies set forth herein, or for personal injury, PNI shall have no liability for any 
indirect or speculative damages (including, but not limited to, consequential, incidental, punitive and special 
damages) relating to the use of or inability to use this Product, whether arising out of contract, negligence, tort, or 
under any warranty theory, or for infringement of any other party’s intellectual property rights, irrespective of 
whether PNI had advance notice of the possibility of any such damages, including, but not limited to, loss of use, 
revenue or profit.  In no event shall PNI’s total liability for all claims regarding a Product exceed the price paid for 
the Product.  PNI neither assumes nor authorizes any person to assume for it any other liabilities. 

Some states and provinces do not allow limitations on how long an implied warranty lasts or the exclusion or 
limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you.  This 
warranty gives you specific legal rights and you may have other rights that vary by state or province.
