Terms and conditions of sale

1. Acceptance - all sales are subject to and expressly conditioned upon the terms and conditions contained herein, and upon buyer's assent thereto. No variation of these terms and conditions will be binding upon seller unless agreed to in writing and signed by an officer or other authorized representative of seller. Seller's commencement of work on or shipment of all or any portion of the goods that are the subject hereof, whichever occurs first, shall be deemed an effective mode of acceptance of buyer's offer to purchase.

2. Changes -orders arising hereunder may be changed or amended only by written agreement signed by both buyer and seller, setting forth the particular changes to be made and the effect, if any, of such changes on the price and time of delivery. Buyer may not cancel this order unless such cancellation is expressly agreed to in writing by seller. In such event, seller will advise buyer of the total charge for such cancellation, and buyer agrees to pay such charges, including, but not limited to, storage and shipment costs, costs of producing non-standard materials, costs of purchasing non-returnable materials, cancellation costs imposed on seller by its suppliers, and any other cost resulting from cancellation of this order by buyer which is permitted by seller. Certification of such costs by seller's independent public accountants shall be conclusive on the parties hereto.

3. Delivery, claims, delays - all sales are fob seller's shipping point unless otherwise noted. If shipping and handling charges are quoted or invoiced, they will include charges in addition to actual freight costs. Delivery of the goods to the carrier at seller's shipping point shall constitute delivery to buyer and buyer shall bear all risk of loss or damage in transit. However, seller reserves the right, in its discretion, to determine the exact method of shipment. Seller reserves the right to make delivery in installments, all such installments to be separately invoiced and paid for when due per invoice, without regard to subsequent deliveries. Delay in delivery of any installment shall not relieve buyer of buyer's obligations to accept remaining deliveries.

Immediately upon buyer's receipt of any goods shipped hereunder, buyer shall inspect the same and shall notify seller in writing of any claims for shortages, defects or damages and shall hold the goods for seller's written instructions concerning disposition. If buyer shall fail to so notify seller within five days after the goods have been received by buyer, such goods shall conclusively be deemed to conform to the terms and conditions hereof and to have been irrevocably accepted by the buyer.

Seller shall not be liable for any loss, damage or penalty as a result of any delay in or failure to manufacture, deliver or otherwise perform hereunder due to any cause beyond seller's reasonable control, including, without limitation, unsuccessful reactions, act of buyer, embargo or other governmental act, regulation or request affecting the conduct of seller's business, fire, explosion, accident, theft, vandalism, riot, acts of war, strikes or other labor difficulties, lightning, flood, windstorm or other acts of god, delay in transportation, or inability to obtain necessary labor, fuel, materials, supplies or power at current prices.

4. Allocation of goods - if seller is unable for any reason to supply the total demands for goods specified in buyer's order, seller may allocate its supply among any or all buyers on such basis as seller may deem fair and practical, without liability for any failure of performance which may result.

5. Payment - terms of sale are net 30 days of date of invoice, unless otherwise stated. If the financial condition of buyer results in the insecurity of seller, in its sole and unfettered discretion, as to the ultimate collection of the purchase price, seller may, without notice to buyer, delay or postpone the delivery of the products; and seller, at its option, is authorized to change the terms of payment to payment in full or in part in advance of shipment of the entire undelivered balance of said products. In the event of default by buyer in the payment of the purchase price or otherwise, of this or any other order, seller, at its option, without prejudice to any other of seller's lawful remedies, may defer delivery, cancel this contract, or sell any undelivered products on hand for the account of buyer and apply such proceeds as a credit, without set-off or deduction of any kind, against the contract purchase price, and buyer agrees to pay the balance then due to seller on demand. Buyer agrees to pay all costs, including, but not limited to, reasonable attorney and accounting fees and other expenses of collection resulting from any default by buyer in any of the terms hereof.

6. Taxes and other charges - any use tax, sales tax, excise tax, duty, custom, inspection or testing fee, or any other tax, fee or charge of any nature whatsoever imposed by any governmental authority, on or measured by the transaction between seller and buyer shall be paid by buyer in addition to the prices quoted or invoiced.
