E. Where Products have limited life or may deteriorate through age or other factors such as improper storage, or where industry-accepted visual imperfections exist, such limited life, deterioration, or imperfection is explicitly agreed to not be a defect in material or workmanship or a failure to conform to specification as contemplated herein.

C. If Signature Science furnished Buyer with advice or other assistance concerning any Product supplied hereunder or any equipment in which any such Product may be installed, which advice is not explicitly required pursuant to the order or other written agreement between the parties, the furnishing of such advice or assistance shall not subject Signature Science to any liability, whether in contract, warranty, tort (including negligence), or otherwise.

D. In no event, whether as a result of breach of contract, warranty, accident, tort (including negligence), failure of a remedy to accomplish its purpose, reliance on result, or otherwise, shall Signature Science be liable for any incidental or consequential damages, including but not limited to, loss of profits or revenue, loss of use, damage to associated equipment, or cost of substitute equipment or products.

If a request to cancel Training is received fourteen (14) calendar days or less prior to the first day of Training, no refund will be provided, and any additional expenses incurred by Signature Science in complying with the request to cancel will be immediately due and payable by Buyer. Signature Science reserves the right to cancel Training up to a minimum of ten (10) business days prior to the first day of Training.
