GAI-Tronics equipment supplied hereunder shall be free of defects in material and workmanship, shall
comply with the then-current product specifications and product literature, and if applicable, shall be fit

specified and agreed upon, and (b) Buyer’s claim is made within the warranty period set forth above,
Buyer may return such goods to GAI-Tronics’ nearest depot repair facility, freight prepaid, at which time
they will be repaired or replaced, at Seller’s option, without charge to Buyer. Repair or replacement shall
be Buyer’s sole and exclusive remedy. The warranty period on any repaired or replacement equipment
shall be the greater of the ninety (90) day repair warranty or one (1) year from the date the original

shall be performed in accordance with the standard of care with which such services are normally
provided in the industry. If the services fail to meet the applicable industry standard, GAI-Tronics will

be deemed waived unless it is made in writing within a reasonable time after such latent defect is or
should have been discovered by Buyer.
Limitations / Exclusions. The warranties herein shall not apply to, and GAI-Tronics shall not be
responsible for, any damage to the goods or failure of the services supplied hereunder, to the extent
caused by Buyer’s neglect, failure to follow operational and maintenance procedures provided with the
