However, Damages will not include loss of opportunity, loss of profit, damages caused by exceptional circumstances, incidental damages, consequential damages, etc., and DISCO will not be liable for the compensation of them under any circumstances. In any case, DISCO’s liabilities under the transaction of the DISCO Products and/or Service shall be limited up to the total amount paid by customer to DISCO for the DISCO Products and/or Service specified in each individual transaction. Even though there are several causes in the damages to the specific DISCO Products of or Service for customer, such limitation shall not be increased.
In addition, DISCO will only be liable for the compensation under and subject to the Defects objectively being proved that they were due to the reasons attributable to DISCO (initial failure, improper design, unachieved specification, obvious deficiencies in Service and evident violation to customer’s instruction, etc.).
Notwithstanding the foregoing, in the case that customer and DISCO agree with different terms and conditions relating to the Damages on or after August 14, 2015 (the publish date of this policy on this HP), such different terms and conditions will be applied.
