1. Acceptance of Terms and Conditions
2. These terms and conditions (the “Terms and Conditions”) govern the sale of all lighting fixtures, lamps, UVC air disinfection products and accessories (the “Products”) by Ecosense Lighting, Inc. (“Ecosense”) to the party purchasing Products from Ecosense (“Buyer”), unless and to the extent Ecosense explicitly agrees otherwise in writing. The offer and sale of Products as described in the applicable quote or similar document is conditioned upon the acceptance by Buyer of these Terms and Conditions, which together with the sales acknowledgement form or similar document(s) regarding the purchase of Products constitute the “Agreement.” These Terms and Conditions may be updated by Ecosense from time to time, and the order of Products from Ecosense constitutes acceptance of the terms and conditions in effect at the time the order is accepted.
3. Any terms and conditions different from or in addition to these Terms and Conditions that are set forth on any document or documents issued by Buyer or Ecosense are hereby rejected, and any such terms shall be wholly inapplicable to any sale of the Products made by Ecosense to Buyer and shall not be binding in any way on Ecosense, unless acknowledged and agreed in a written agreement executed by an officer of Ecosense.
4. Any quotation received from Ecosense is open for acceptance for thirty (30) days from the date of the quotation, unless stated otherwise in the quotation, but any quotation may be modified, withdrawn, or revoked by Ecosense at any time prior to the actual receipt and confirmation by Ecosense of Buyer’s acceptance thereof.
5. Cancellations.
6. Orders accepted by Ecosense cannot be changed, rescheduled or cancelled without the prior written consent of Ecosense. Without limiting any other remedies, if Buyer changes, reschedules or cancels an order without prior consent, Ecosense reserves the right to charge Buyer for costs incurred for such order, up to the full sales price of the Products subject to such order. Partial cancellations may affect freight prepayment, and orders which have already been processed will be considered separate orders for purposes of freight prepayment.
7. Orders received as “Hold for Release” or “Will Advise” are not processed for manufacture until a formal release is received by Ecosense. Any such order will be subject to the pricing terms at the time of release.  Buyers who place orders on a “Hold for Release” basis and subsequently cancel the order prior to release may be subject to a cancellation charge for product engineering, submittal drawings and administration relating to such cancelled order.
8. All sales are final. No Products will be accepted for return, and no credit will be allowed on any Products, unless returned in accordance with Section 9 of these Terms and Conditions.
9. Pricing. Pricing for the Products shall be determined by Ecosense in its sole discretion and may be changed at any time by Ecosense on notice to Buyer subject to these Terms and Conditions. Unless otherwise specified by Ecosense, prices for such Products are for the quantity specified and do not include charges for transportation, insurance, special packaging, marking, applicable sale service taxes, value added taxes, export or import licenses, fees, taxes, duties and the like; Buyer shall bear the cost of  such charges in addition to the prices invoiced. Price quotations are in U.S. Dollars and are valid for delivery only to locations within the United States unless stated otherwise in Ecosense’s sales order acknowledgment.  Ecosense reserves the right to make substitutions and modifications in the specifications of the Products sold if such substitutions or modifications do not cause a material adverse effect on overall performance of the Products.  Ecosense further reserves the right to discontinue any Products at any time without notice to Buyer.
10. Payment.
    1. Unless Buyer’s credit is pre-approved by Ecosense in writing, payment is due in full prior to shipment of any Products. Ecosense shall have the right, at any time, to require an irrevocable letter of credit or other assurance of payment satisfactory to Ecosense as a condition to the acceptance of any order. A letter of credit or prepayment shall be required for any shipments outside the United States and for special or customized Products. In the event of any default by Buyer in the payment of any fees or charges due or other default by Buyer, Ecosense shall have the right to refuse performance of any purchase order and shipment of any Products until payments are brought current and Ecosense may suspend, delay or cancel any credit, shipment or other obligation of Ecosense if payments are past due. Such right shall be in addition to, and not in lieu of, any other rights and remedies available under these Terms and Conditions or at law.
    2. In addition to any other rights and remedies Ecosense may have under applicable law, interest will accrue on all late payments at the rate of ten percent (10%) per annum or the maximum rate permitted by law, whichever is lower, from the due date until payment has been made in full, plus legal fees associated with the collection of such past-due amounts.
11. Shipment and Quantities.
    1. Products will be shipped in accordance with sales order acknowledgement received from Ecosense, unless otherwise agreed in writing by Ecosense. Shipment dates communicated or acknowledged by Ecosense are approximate only, and Ecosense shall not be liable for, nor shall Ecosense be in breach of its obligations to Buyer for, any delays to the shipment date except as set forth in Section 5(b).
    2. In the event of any delay in the shipment of the Products of more than thirty (30) days following the shipment date set forth in the sales order acknowledgement form, Buyer will give Ecosense written notice of such delay or failure to ship and a 30-day period within which to cure. If Ecosense does not ship within such time period, Buyer’s sole and exclusive remedy is to cancel the affected and unshipped portions of the purchase order. Except as set forth in this Section 5(b), Ecosense will have no liability associated with the failure to ship the Products by the shipment date communicated to Buyer.
    3. Unless otherwise specified in a sales order acknowledgement form, Ecosense shall ship the Products to Buyer FOB destination point. The destination point is the delivery location designated by Buyer. In cases where Buyer arranges for pick-up of the goods and shipping, Buyer is deemed to have taken control of the goods at the time the product leaves the Ecosense facility.
    4. Ecosense will attempt to redirect loose parcel shipments at Buyer’s request, but any redirected shipment may incur additional fees. Ecosense is not responsible for any delays, damage and/or loss of goods resulting from the redirection of shipments currently in transit between Ecosense’s shipping facility and the receiving party’s new address.
    5. Shipments may be tendered in several lots. In the absence of specific instructions, Ecosense will select the carrier and ship freight prepaid.  Surface freight for non-expedited orders in the contiguous United States for fixture orders in excess of $5,000 will be paid by Ecosense. Soraa lamp purchase orders over $1,000 shipped within the contiguous United States are free freight (over $2,000 for Hawaii, Alaska and Canada).  UVC air disinfection product purchases are excluded from free freight and will be charged to the Buyer. Except as otherwise provided in these Terms and Conditions, all shipping costs shall be the responsibility of Buyer, including without limitation, in cases where Buyer, for any reason, requests deliveries of the Products in a manner that is inconsistent with Ecosense’s standard shipping procedures.  Buyer shall also be responsible for all costs associated with premium freight and any resulting overtime required to make deliveries in accordance with Buyer’s required delivery schedule.
    6. Ecosense will not be deemed to assume any liability in connection with any shipment because of the selection of a carrier or its failure to obtain insurance. Title and risk of loss or damage to the Products will pass to Buyer when delivery is made to the carrier.
    7. If Buyer fails to take delivery of any Products, then Ecosense may deliver the Products on consignment at Buyer’s cost.
    8. In the event production is curtailed for any reason, Ecosense shall have the right to allocate its available production and Products, in its sole discretion, among its various customers and as a result may sell and ship to Buyer fewer Products than specified in the Agreement.
    9. Subject to Section 5(b) of these Terms and conditions, Ecosense shall have the right to make full or partial shipment of the Products, and Buyer shall be responsible for payment of the Products received, regardless of any delay or state of the shipment or partial shipment, providedthat the foregoing does not limit Buyer’s remedies under the limited warranty in Section 8.
12. Ownership Rights.
    1. The sale of the Products furnished hereunder does not convey any license by implication, estoppel, or otherwise, under any proprietary or intellectual property rights of Ecosense. In all cases, intellectual property rights in and relating to the Products, including to all manufacturing information and process technology related to the development, manufacture and sale of the Products, shall be and remain the exclusive property of Ecosense and its licensors or suppliers. Any design, development and manufacture of the Products by Ecosense for Buyer shall not be deemed to produce a work made for hire and shall not give a Buyer any intellectual property right interest in the Products or any portion thereof.

All such materials relating to the Products supplied by Ecosense (except information as may be established to be in the public domain without fault or action of Buyer or disclosed pursuant to judicial or government action) shall be received in confidence, and Buyer shall exercise reasonable care to hold such information in confidence and in no event less care than Buyer exercises to protect Buyer’s confidential information. Buyer may only use such information for purposes of installing and operating the Products as specified by Ecosense.
13. Force Majeure.
14. Ecosense shall not be liable for any failure or delay in performance if:
    • such failure or delay results from interruptions in the Product manufacturing and/or delivery process; or
