If Viatran determines that any Product does not conform to the foregoing warranty, Buyer’s sole remedy, and Viatran’s entire liability, for breach of the foregoing warranty shall be the repair or replacement, at Viatran’s option, of the non-conforming Product or part or, if neither is, in Viatran’s opinion, commercially feasible, a refund of the purchase price paid for the Product.

At Viatran’s option, replacement of any Product may be made by substitution of another Product that is substantially similar in form and function. The warranty on repaired or replacement Products furnished pursuant to this warranty shall be limited to the unexpired portion of the original warranty period.
