Cardinal will notify PGT if Cardinal intends to implement a modification of any of the Specifications of the Products or the manufacturing processes for the Products, which reasonably could be expected to change the such Specifications (collectively, “Modifications”). With respect to Products covered by accepted Purchaser Orders, Cardinal shall not implement any Modifications without PGT’s prior written consent, which consent shall not be unreasonably withheld. If PGT does not respond to Cardinal’s notification of a proposed Modification within ninety (90) days after receiving the same, Cardinal may reject future orders for the Products that would be affected by such Modification. If such Modification is not accepted/consented to by PGT, Cardinal shall not implement such Modification, but PGT shall not unreasonably withhold its consent to any requested Modification, so long as the Modification is not likely to degrade, harm or lower the quality, aesthetics, durability, or other characteristics of the Products that would be affected by the Modification.
