1. PRICES
All prices published by us or quoted by our representatives may be changed at any time without notice. Written quotations expire automatically sixty (60) days from the date issued and arc subject to change or termination by notice during that period. All prices are subject to adjustment on account of specifications, quantities, shipment arrangements or other terms and conditions which are not part of the original price quotation. Prices are exclusive of all excise, sales, use and other taxes imposed by any federal, state, municipal or other governmental authority, all of which taxes shall be paid by the purchaser. The purchaser is responsible for obtaining and providing to us any certificate of exemption or similar document required to exempt any sale from sales, use or similar tax liability. All prices shall be as specified by us or, if no price has been specified, shall be our price in effect at the time of delivery.

2. TERMS OF PAYMENT
Unless otherwise expressly agreed to by us in writing and signed by an authorized representative, terms are as set forth on the reverse side hereof. We reserve the right at any time to require full or partial payment in advance, or to revoke any credit previously extended, if, in our judgment, the purchaser's financial condition does not warrant proceeding on the terms specified. Overdue payments shall he subject to finance charges computed at a periodic rate (to the extent permitted by law) of 11/2% per month (18% per year), plus all costs and expenses, including reasonable attorneys' fees, incurred by us in collecting such overdue amounts. Amounts owed by the purchaser with respect to which there is no dispute shall be paid without set-off for any amounts which the purchaser may claim are owed by us and regardless of any other controversies which may exist.

3. DELIVERY
Unless otherwise specified, all sales are F.O.B, our premises in Ayer, Massachusetts, and the time of delivery shall be the time when the product is ready for pickup at that location by the purchaser or by a carrier for delivery to the purchaser. Without in any way limiting the generality of paragraph 10, we shall not be liable for any loss or damage resulting from any delay in delivery or failure to deliver which is due to any cause beyond our control, including, without limitations, acts of nature, unavailability of supplies or sources of energy, riots, wars, fires, floods, epidemics, lockouts, strikes and slowdowns, delays in delivery by our suppliers, or acts or omissions of the purchaser. In the event of delay due to any such cause, time for delivery shall be extended for a period equal to the duration of the delay and the purchaser shall not be entitled to refuse delivery or otherwise be relieved of any obligations as a result of the delay. If, as a result of any such cause, any scheduled delivery is delayed for a period in excess of three (3) months, we may, at our option, by written notice to the purchaser, cancel that and all future deliveries without further liability or obligation of any kind. Products on which delivery is delayed due to any cause within the purchaser's control may be placed in storage by us at the purchaser's risk and for its account. The purchaser shall be liable for all costs and expenses incurred by us in holding or storing products for the purchaser or at the purchaser's request.

To the extent that this document may constitute an acceptance, such acceptance is expressly conditioned on the purchaser's assent to any additional or inconsistent terms and conditions set forth in this document.

2. DELIVERY; NOTICE OF LABOR DISPUTES
Time is of the essence in the performance of this Purchase Order. If delivery schedule cannot be met, Seller shall promptly notify Buyer of the earliest possible date for delivery. Notwithstanding such notice, and unless a substitute delivery date has been expressly agreed to by Buyer in writing, Seller's failure to effect delivery in the date specified shall entitle Buyer (a) to cancel this order without any liability to Buyer or (b) to purchase substitute items elsewhere, and to hold Seller accountable for any loss or additional costs incurred by Buyer. Seller shall notify Buyer immediately of any actual or potential labor dispute which is delaying or threatens to delay the timely performance of this order.

9. CHANGES
Buyer may, at any time and from time to time by written notice to Seller, suspend work, make changes in specifications, designs, testing, packing and destinations and postponements in delivery schedules.

Any claims by Seller for adjustment under this clause shall be made within 10 days after receipt of written notice for the suspension or change, and any claim not made within the 10 day period shall be deemed waived. Such claim shall be followed as soon as practicable with specification of the amount claimed and supporting cost figures in reasonable detail.
