GENERAL TERMS AND CONDITIONS FOR THE SALE OF GOODS AND SERVICES

Applicability.
(a) These terms and conditions of sale (these “Terms”) are the only terms governing the sale of the
goods (the “Goods”) and services (the “Services”) provided by BioChem Systems, Inc. (the “Seller”) to the buyer named on
the Seller’s sales proposal (each, a “Proposal”) or the purchase order accompanying these Terms (the “Buyer”).
Notwithstanding anything herein to the contrary, if a written master contract signed by both parties is in existence covering
the sale of the Goods and Services covered hereby, the terms and conditions of that contract prevail to the extent they are
inconsistent with these Terms.

(b) The accompanying Proposal, purchase order, (together, the “Sales Confirmation”) and these
Terms (collectively, this “Agreement”) comprise the entire agreement between the parties, and supersede all prior or
contemporaneous understandings, agreements, negotiations, representations and warranties, and communications, both
written and oral. These Terms prevail over any of Buyer’s general terms and conditions of purchase regardless of whether
or when Buyer has submitted its purchase order or such terms. Fulfillment of Buyer’s order does not constitute acceptance
of any of Buyer’s terms and conditions and does not serve to modify or amend these Terms.

(c) Notwithstanding anything to the contrary contained in this Agreement, Seller may, from time to
time change the Services without the consent of Buyer provided that such changes do not materially affect the nature or
scope of the Services, or the fees or any performance dates set forth in the Sales Confirmation.

delivery of the Goods within one day of Seller’s written notice that the Goods have been delivered to the Delivery Point.
Buyer shall be responsible for all loading costs and provide equipment and labor reasonably suited for receipt of the Goods
at the Delivery Point and will unload and release all transportation equipment promptly so Seller incurs no demurrage or

Buyer. Each shipment will constitute a separate sale, and Buyer shall pay for the units shipped whether such shipment is in
whole or partial fulfillment of Buyer’s purchase order.

(d) If for any reason Buyer fails to accept delivery of any of the Goods on the date fixed pursuant to
Seller’s notice that the Goods have been delivered at the Delivery Point, or if Seller is unable to deliver the Goods at the
Delivery Point on such date because Buyer has not provided appropriate instructions, documents, licenses or
authorizations: (i) risk of loss to the Goods passes to Buyer; (ii) the Goods will be deemed to have been delivered; and (iii)

and expenses (including, without limitation, storage and insurance).

(e) With respect to the Services, Buyer shall (i) cooperate with Seller in all matters relating to the
Services and provide such access to Buyer’s premises, and such office accommodation and other facilities as may

remedies for any non-delivery of Goods.

Quantity. If Seller delivers to Buyer a quantity of Goods of up to 5% more or less than the quantity set
forth in the Sales Confirmation, Buyer shall not be entitled to object to or reject the Goods or any portion of them by reason
of the surplus or shortfall and shall pay for such Goods the price set forth in the Sales Confirmation adjusted pro rata.
Shipping Terms. Seller shall make delivery in accordance with the terms on the face of the Sales
Confirmation, or FOB Seller’s location if the Sales Confirmation does not so specify (the “Shipping Terms”).
Title, Risk of Loss, Intellectual Property.
(a) Unless otherwise specified in the Shipping Terms, title and risk of loss

Buyer in, to and under the Goods, wherever located, and whether now existing or hereafter arising or acquired from time
to time, and in all accessions thereto and replacements or modifications thereof, as well as all proceeds (including insurance
proceeds) of the foregoing. The security interest granted under this provision constitutes a purchase money security

Seller to seek all available remedies in law or at equity, including injunctive relief.

(d) If Buyer improves, enhances, or modifies any Seller Goods or related process, accessory, or
workflow, Buter irrevocably transfers and assigns to Seller without further compensation (and Seller owns all right, title,
and interest in) all intellectual property rights in or to such improvement, enhancement, or modification. If any of the
foregoing transfers and assignments by Buyer are to any extent ineffective, Buyer grants to Seller an exclusive, royalty-free,
irrevocable, perpetual, worldwide license to make, use, market and sell and freely exploit such intellectual property rights.
At no cost to Seller, Buyer shall take, and shall cause its employees and agents to take, all actions reasonably requested by
Seller, from time to time, to fully vest, perfect, or defend Seller’s intellectual property rights including, without limitation,

providing documents and information useful or necessary to register, apply for, or maintain any of Seller’s intellectual
property rights.

Buyer’s Acts or Omissions. If Seller’s performance of its obligations under this Agreement is prevented or
delayed by any act or omission of Buyer or its agents, subcontractors, consultants, or employees, Buyer shall not deem
Seller in breach of its obligations under this Agreement or otherwise liable for any costs, charges, or losses sustained or
incurred by Buyer, in each case, to the extent arising directly or indirectly from such prevention or delay.

therewith. Buyer shall ship, at its expense and risk of loss, the Nonconforming Goods to Seller’s facility located at 1812

Buyer’s shipment of Nonconforming Goods, ship to Buyer the replaced Goods to the Delivery Point.
(c) Buyer acknowledges and agrees that the remedies set forth in Section

8(b) are Buyer’s exclusive remedies for the delivery of Nonconforming Goods. Except as provided under Section 8(b), all
