1. Acceptance

A purchase order is an offer by Shattuck Labs, Inc. or any of its affiliates (the “Buyer”) for the purchase of the specified goods (the “Goods”) or services (the “Services”), from the specified vendor (the “Seller”) in accordance with and subject to these terms and conditions (the “Terms”; together with the specifications on the face of the purchase order, the “Order”). This Order will be deemed accepted by the Seller upon the first of the following to occur: (a) Seller making, signing, or delivering to Buyer any letter, form, or other writing or instrument acknowledging acceptance; (b) any performance by Seller under the Order; (c) Seller’s receipt of any payment, progress, partial or full, from Buyer under the Order; or (d) the passage of ten (10) days after Seller’s receipt of the Order without written notice to Buyer that Seller does not accept. Unless the parties have entered into a written contract that, by its terms, is expressly intended to govern the Goods and/or Services included in this Order, this Order, together with any documents incorporated herein by reference, constitutes the sole and entire agreement of the parties with respect to the Order and supersedes all prior or contemporaneous understandings, agreements, negotiations, representations and warranties, and communications, both written and oral, with respect to the subject matter of the Order. This Order expressly limits Seller’s acceptance to the terms of the Order, and Buyer’s submission of this Order is conditioned on Seller’s agreement that that any terms different from or in addition to these Terms, whether communicated orally or contained in any purchase order confirmation, invoice, acknowledgement, release, acceptance or other written correspondence, irrespective of the timing, shall not form a part of the Order, even if Seller purports to condition its acceptance of the Order on Buyer’s agreement to such different or additional terms.

2. Delivery

Seller shall deliver the Goods and perform the Services at the delivery point or shipping address specified on this Order (the “Delivery Location”), and on or before the date(s) specified in this Order (the “Delivery Date”). If the Order does not specify a Delivery Date, Seller shall provide the Goods and Services as if time is of the essence. If Seller anticipates a delay in the delivery of the Goods or Services, Seller shall immediately notify Buyer. In the event that Seller fails to deliver the Goods or Services by the Delivery Date, Buyer may purchase substitute Goods or Services elsewhere and charge Seller for any additional expense incurred relating to the purchase of the substitute Goods or Services. If delivery of the Goods and Services is not complete by the Delivery Date, Buyer may, without liability, and in addition to its other rights and remedies, terminate this Order, by notice effective when received by Seller, as to Goods and Services not yet delivered or rendered.

3. Inspection

All Goods and Services shall be received subject to Buyer’s inspection and acceptance or rejection. In case any Goods or Services are found to be defective or otherwise not in conformity with the requirements of this Order, Buyer shall have the right to reject the same and/or require that such Goods or Services be corrected or replaced promptly with satisfactory Goods or Services. If Buyer so rejects the Goods or Services or if Seller, when requested by Buyer, fails to proceed promptly with the replacement or correction thereof, Buyer may immediately terminate this Order pursuant to Section 8 and purchase substitute Goods or Services elsewhere and charge Seller for any additional expense incurred relating to the purchase of the substitute Goods or Services. Rejected defective or non-conforming Goods or Services will be held for Seller’s instructions and at Seller’s risk and expense and, if Seller so directs, will be returned at Seller’s expense. Payment for Goods or Services on this Order prior to inspection shall not constitute an acceptance thereof.

4. Cumulative Remedies

The rights and remedies under this Order are cumulative and are in addition to any other rights and remedies available at law or in equity or otherwise.

5. Price and Payment

The price of the Goods and Services is the price stated on the face of this Order (the “Price”). Unless otherwise specified in the Order, the Price shall include any applicable transportation charges, insurance costs, shipping and handling fees and taxes. Seller shall invoice Buyer for the Order within thirty (30) days of delivery. Unless otherwise stated in the Order, Buyer shall pay all properly invoiced amounts due to Seller within sixty (60) days after Buyer’s receipt of such invoice, except for any amounts disputed by Buyer. The parties shall seek to resolve all such disputes expeditiously and in good faith. Seller shall continue performing its obligations under the Order notwithstanding any such dispute. Without prejudice to any other right or remedy, Buyer reserves the right to set off any amount owing to it by Seller against any amount payable by Buyer to Seller.

6. Change Order

Buyer may, from time to time, initiate changes by issuing to Seller written notices (each, a “Change Order”) that alter, add to, or deduct from the Goods and Services, but that are otherwise subject to the Terms, and Seller shall promptly comply with any Change Order. If a change causes an increase or decrease in cost and/or time required for performance of the Goods and Services, an equitable adjustment shall be made and the Order shall be modified accordingly. If any specified condition of the Change Order cannot be achieved or met by Seller, Buyer must be notified and must accept in writing any variation prior to shipment or delivery.

7. Termination

Buyer may terminate an Order, in whole or in part, for any reason upon ten (10) days’ prior written notice to Seller. In addition to any remedies provided herein, Buyer may terminate this Order with immediate effect, either before or after acceptance of Goods or Services, if Seller has breached any of the Terms herein. If the Seller becomes insolvent, commences or has commenced by it or against it bankruptcy proceedings, receivership, reorganization or assignment for the benefit of creditors, then Buyer may immediately terminate this Order. To the extent this Order covers stock Goods or any Services, Buyer’s only obligation is to pay for Goods and Services received and accepted by Buyer prior to the notice of termination. To the extent this Order covers Goods manufactured or fabricated to Buyer’s specifications, Seller shall immediately cease all performance hereunder upon receipt of notice of termination, and, if Seller has not breached these Terms, Buyer shall reimburse Seller for the actual, direct cost to Seller of such Goods which have, at the time of such cancellation, been wholly or partially manufactured, not to exceed the Price.
