the applicable services or (ii) credit or refund the price of such services at the pro rata contract rate and such shall be Seller’s sole 

obligation and the exclusive remedy for breach of the foregoing warranty on services. Products manufactured by a third party (“Third

SELLER’S WARRANTY OF TITLE TO THE GOODS, SELLER EXPRESSLY DISCLAIMS AND EXCLUDES ALL OTHER WARRANTIES 

WHATSOEVER, WHETHER, EXPRESSED OR IMPLIED, ORAL, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED 

TO  MERCHANTABILITY,  FITNESS  FOR A  PARTICULAR  PURPOSE,  NON-INFRINGEMENT  OF  THIRD  PARTY  INTELLECTUAL 

PROPERTY AND ANY WARRANTIES ARISING FROM TECHNICAL ADVICE OR RECOMMENDATIONS, COURSE OF DEALING 

OR OF PERFORMANCE, CUSTOM OR USAGE OF TRADE. Seller’s obligations do not cover normal wear and tear or deterioration, 

defects in or damage to any goods resulting from improper installation, accident or any utilization, maintenance, repair or modification of 

the goods, or any use that is inconsistent with Seller’s instructions as to the storage, installation, commissioning or use of the goods or 

the designed capabilities of the goods or that, in its sole judgment, the performance or reliability thereof is adversely affected thereby, or
