Overview

These Terms of Sale (the "Terms") govern your purchase of carbon dioxide reduction (CDR) credits from Gevo, Inc. and/or any of its affiliates, who will be referred to herein as "Gevo", "Seller," "we," or "us". By ordering, purchasing, or accepting delivery of CDR credits, you agree to these Terms of Sale. If you are acting on behalf of a company, you represent that you are authorized to bind that company and "you" refers to that company.

Product Description; No Guarantee of Vintage Year

CDR credits represent quantifications of carbon removal or storage meeting criteria determined by applicable standards and registries. Credits may be associated with a "vintage year," which generally refers to the period when the underlying carbon removal occurred or was verified. You acknowledge and agree that:

• Any descriptions, listings, or references to a vintage year are informational only.
• The sale and purchase of CDR credits under these Terms are made without any warranties, representations, or guarantees regarding the vintage year of the credits, including whether any particular credit will reflect a specific year or range of years.

"As Is" and "As Available"

To the maximum extent permitted by law, all CDR credits and any related information, certificates, documentation, account entries, or registry postings are provided "as is" and "as available." Without limiting the foregoing, Gevo disclaims all warranties, whether express, implied, statutory, or otherwise, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, or that credits will meet your expectations or achieve any particular outcome.

Final, Non-Cancellable Sales; No Refunds or Returns

All orders are final upon submission. Orders may not be cancelled, revoked, or rescinded by you once placed. To the maximum extent permitted by law, there are no refunds, returns, chargebacks, offsets, or credits of any kind once a credit is posted, issued, or retired (as applicable) on the Puro Registry.

Registry Posting; Definition of "Posted"; Registry Outside Seller's Control

For purposes of these Terms:

• A credit is considered "posted" on the Puro Registry when the registry reflects the credit as recorded in your designated registry account, or, if you have instructed Gevo to retire the credit on your behalf, when the registry reflects the retirement referencing your designation.
• You acknowledge that registry operations, processes, availability, timing, performance, verification, validation, and display (including the assignment of any unique identifiers, vintage year attributes, or timestamps) are administered solely by the registry operator and are outside Gevo's control.
• Posting, issuance, and retirement timelines are subject to the registry's procedures, reviews, and schedules. Gevo does not control and is not responsible for delays, errors, corrections, changes, suspensions, downtime, or other registry actions or inactions.
• Your cooperation, timely provision of requested information, and compliance with registry requirements may be necessary to complete posting, issuance, transfer, or retirement.

Transfers, Retirement, and Instructions

If you request transfer to a designated registry account or retirement on your behalf, you authorize Gevo to submit corresponding instructions to the registry. You are responsible for ensuring your registry account is active, properly configured, and able to receive the credits. If transfer or retirement cannot be completed due to issues with your account or your instructions, Gevo may hold the credits for your benefit pending updated instructions. Holding credits does not entitle you to any refund or price adjustment.

Price and Payment

Prices will be as quoted at checkout unless otherwise agreed in writing. Prices shown are in U.S. dollars. You agree to pay all amounts due using the payment method you select. If you pay by means of an international account, the price may fluctuate with exchange rates and/or you may be charged foreign conversion charges and fees by your financial institution. You authorize Gevo to collect payment and acknowledge that all charges are non-refundable as set forth in these Terms. Any taxes, duties, or fees imposed on the sale, transfer, issuance, or retirement of credits are your responsibility unless Gevo expressly agrees otherwise in writing.

No Offset or Double Counting Advice

You are solely responsible for determining the suitability of any credits for your intended use, including for claims, reporting, or offsetting. Gevo does not provide legal, accounting, scientific, or reporting advice and does not warrant that any credit will be recognized by any third party, standard, program, framework, or authority for any particular purpose.

Limitation of Liability; Disclaimer of Consequential Damages

To the maximum extent permitted by law, in no event will Gevo be liable for any indirect, incidental, special, exemplary, punitive, or consequential damages, or for any lost profits, lost revenues, lost savings, loss of use, loss of business, loss of goodwill, or claims by third parties, arising out of or related to the vintage year of any credit, registry posting, issuance, transfer, retirement, delays or failures in registry operations, or your use or inability to use any credits, even if advised of the possibility of such damages. To the maximum extent permitted by law, Gevo's total aggregate liability for any and all claims arising out of or related to these Terms or the credits will not exceed the total amount you paid to Gevo for the specific credits giving rise to the claim.

Force Majeure

Gevo will not be liable for any delay or failure to perform due to events or circumstances beyond its reasonable control, including changes in laws or standards, registry outages or changes, acts of God, war, terrorism, cyber events, labor disputes, or third-party service failures.

Compliance and Prohibited Uses

You agree to comply with applicable laws, standards, and registry rules. You will not use credits to make false, misleading, or deceptive claims. If a law, standard, or registry policy change affects the availability, transferability, or attributes of credits, your sole remedy is as set forth in these Terms.

Indemnification

You agree to defend, indemnify, and hold Gevo and our officers, directors, employees, and agents harmless from and against any and all claims, damages, losses and expenses of any kind (including reasonable legal fees and costs) arising from or related to (1) your misuse of the CDR credits, (2) your negligence or willful misconduct, or (3) your violation of these Terms, or any applicable law or regulation. We reserve the right to take exclusive control and defense of any claim, and you will cooperate fully with us in asserting any available defenses.

Errors; Corrections

If a manifest error occurs in a listing or confirmation, Gevo may correct the error by notice to you. If a registry or third party corrects, voids, or amends a posting, issuance, or retirement, you agree to cooperate in good faith to reflect the corrected status. Such corrections do not give rise to refunds unless expressly stated in these Terms.

Notices and Contact

All notices to Gevo must be sent to carbon@gevo.com and 345 Inverness Drive South, Building C, Suite 310, Englewood, CO 80112. We may provide notices to you via the email address or other contact information you provided at checkout.

Governing Law; Venue

These Terms are governed by the laws of Delaware, without regard to conflicts of laws principles. The parties consent to the exclusive jurisdiction and venue of the state and federal courts located in Denver, Colorado for any dispute arising out of or relating to these Terms or the credits, and waive any objections to personal jurisdiction or forum.

Entire Agreement; Changes; No Waiver

These Terms, together with any order confirmation issued by Gevo, are the entire agreement between you and Gevo regarding your purchase of credits. We may update these Terms prospectively by posting revised terms on this page; your continued purchases after changes become effective constitute acceptance. No waiver will be effective unless in writing and signed by Gevo.

Severability

If any provision of these Terms is held unenforceable, that provision will be enforced to the maximum extent permissible, and the remaining provisions will remain in full force and effect.

Assignment

You may not assign or transfer your rights or obligations under these Terms without Gevo's prior written consent. We may assign these Terms to any Gevo affiliate or in connection with a merger, acquisition, corporate reorganization, or sale of assets.
