		16.1	Neither Buyer nor
                                         Seller shall be liable for any delay in or failure to manufacture, ship or deliver due
                                         to Acts of God, acts of the public enemy, insurrections, riots, fires, explosions, floods,
                                         strikes, labor disputes, war, acts of terrorism, civil commotion, breakdowns of or damage
                                         to plants, mines, equipment or facilities, economic or other shutdown of plant or mine

                                         shall justify the suspension of performance of either Party, including the manufacture
                                         and delivery of Product, and shall extend the time of performance on the part of the

                                         contained to the contrary notwithstanding. Seller may in its sole discretion, but shall
                                         not be required to make up all or a portion of any deficiencies in deliveries hereunder
                                         caused by such event of Force Majeure.



 


		16.2	If the event of Force Majeure continues to affect a specific
