Systems, and Trailers), components incorporated into equipment, parts, supplies, materials or other personal property (individually
and collectively, “Equipment”) by Seller to Buyer. Buyer acknowledges and agrees that these Terms and Conditions of Sale are
incorporated in, and are a part of, any contract of sale and each quotation, purchase order, invoice, and any other document relat-
ing to the sale of Equipment by Seller to Buyer (these documents are collectively referred to as the “Agreement”).
3. Quotation Expiration. Written quotations signed by Seller are valid for a period of 30 days unless otherwise noted by Seller.

thority unless otherwise expressly noted by Seller.

unpaid on or after 30 days of Seller’s invoice will bear interest at the simple interest rate of 2 percent (2%) per month or the maxi-
mum rate permitted by law, whichever is less. The accrual or payment of any interest as provided above will not constitute a waiv-
er by Seller of any rights and remedies in connection with a default by Buyer. Buyer will pay all court costs, attorney fees, and
other costs incurred by Seller in collecting past-due amounts, including interest. If shipment or delivery of Equipment is delayed by
or at the request of Buyer, payment will remain due in full on the original delivery date for Buyers without credit approval or 30

ment sold by Seller to Buyer, and Seller will have all rights of a secured party under the Uniform Commercial Code with respect to
the Equipment. Buyer appoints Seller as its attorney-in-fact with authority, at Seller’s option, to take actions as Seller deems rea-
sonable in the circumstance to perfect the above security interest in any one or more jurisdictions, and Buyer shall pay all applica-
ble filing fees.
8. Limited Express Warranty. For a period of ninety (90) days from the completion of Seller’s delivery obligation under this
Agreement, Seller warrants that a limited selection of components manufactured by Seller and incorporated into the Equipment
will be free of defects in material and workmanship. A complete list of components covered under this warranty (“Warranty Break-
down”) is available at [www.bwmanufacturing.com/warrantybreakdown] and is incorporated in its entirety into this Agreement. In
the event Buyer has a claim related to the components covered under this warranty, Buyer shall be bound by the then-current
Warranty Breakdown. Buyer’s sole remedy for breach of this warranty is limited to repair and replacement, within the warranty
period, of defective components manufactured by Seller and covered under this warranty pursuant to the Warranty Breakdown.
Buyer is responsible for all shipping costs arising out of any warranty service provided by Seller. SELLER EXPRESSLY DIS-
CLAIMS AND EXCLUDES ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WITH REGARDS TO THE EQUIPMENT AND/

CLUDED IN THE ABOVE REFERENCED WARRANTY, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FIT-
NESS FOR A PARTICULAR PURPOSE. BUYER ASSUMES FULL RESPONSIBILITY THAT THE EQUIPMENT PURCHASED
UNDER THE AGREEMENT MEETS THE SPECIFICATIONS AND/OR INTENDED USE OF BUYER, AND SELLER MAKES NO
REPRESENTATION WITH RESPECT THERETO.
9. Disclaimer of Third-Party Component Warranties. THE SOLE REMEDY AVAILABLE TO BUYER WITH RESPECT TO DE-
FECTS IN THE COMPONENTS MANUFACTURED BY THIRD PARTIES WILL BE AGAINST THE THIRD PARTY MANUFAC-
TURER UNDER ANY APPLICABLE MANUFACTURER’S WARRANTY TO THE EXTENT AVAILABLE TO BUYER. WITH RE-
GARDS TO COMPONENTS MANUFACTURED BY THIRD PARTIES AND INCORPORATED INTO THE EQUIPMENT, SELLER
MAKES NO WARRANTY, EXPRESS OR IMPLIED, RELATING TO THE COMPONENTS, WHETHER BASED ON BREACH OF
WARRANTY OR CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY
IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

tions by governmental authorities; acts, omissions, or delays of Buyer or any other third party; shortages of labor; or without limita-
tion of the above, for any causes reasonably beyond the control of Seller.

solely under the terms and conditions of the Agreement and Seller objects to any and all additional or different terms contained in
any document submitted to Seller by Buyer. Any execution by Seller of any other document submitted by Buyer in connection with
