Exhibit 10.1

AGREEMENT REGARDING PAYOFF AND RELEASE OR AMENDMENT OF NOTES

This AGREEMENT REGARDING PAYOFF AND RELEASE OR AMENDMENT OF NOTES (this “Agreement”) is entered into this 25th day of May, 2020, by and among Carbon Energy Corporation, a Delaware corporation (“Issuer”), Old Ironsides Fund II-A Portfolio Holding Company, LLC, a Delaware limited liability company (“Holder Fund II-A”) and Old Ironsides Fund II-B Portfolio Holding Company, LLC, a Delaware limited liability company (“Holder Fund II-B” and together with Holder Fund II-A, the “Holders”). Holders and Issuer are referred herein as the “Parties” and individually, a “Party.” Any capitalized term used herein but not otherwise defined shall have the meaning given to such term in the Purchase Agreement (as defined below) or the Notes (as defined below), as applicable.

Recitals:

NOW, THEREFORE, in consideration of the promises and covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

l. Payoff Discount. Except for as set forth expressly herein, Issuer hereby acknowledges and reiterates its obligation pursuant to Article 3.4(a)(i) of the Notes to pay any Net Cash Proceeds under the Purchase Agreement to the Holders no later than the third business day following the date of receipt by Issuer of any such Net Cash Proceeds. For the avoidance of doubt, the Net Cash Proceeds required to be paid to Holders include, but not limited to, any amount of the Deposit released to (or due and releasable to) Issuer or for Issuer’s account, any amounts in the Indemnity Escrow Fund returned to (or due and returnable to) Issuer or for Issuer’s account, any amounts paid to (or due and payable to) the Issuer or for Issuer’s account under Article 13.2 of the Purchase Agreement and any amounts paid to (or due and payable to) Issuer or for Issuer’s account with respect to the conveyance to Purchaser of any Purchase Agreement Assets which were initially excluded from the transaction for failure to obtain a Material Required Consent (each such term as defined in the Purchase Agreement).

Notwithstanding the above and in settlement of a dispute among the Parties regarding the appropriate calculation of Net Cash Proceeds with respect to the Purchase Agreement, Holders agree to terminate the Notes and release all outstanding Obligations of Issuer in consideration for the timely payment in cash of the Payoff Discount so long as the Payoff Discount shall be made with Net Cash Proceeds under the Notes and is to be paid to Holders in cash, in two tranches. The first tranche shall be in an amount of at least $10,500,000 (the “Closing Payoff Amount”) and shall be paid, solely with respect thereto, within three business days of the Closing, the second tranche shall be in an amount equal to any other Net Cash Proceeds payable to the Holders pursuant to the preceding paragraph (the “Final Settlement Statement Payoff Amount”) and shall be paid within three business days of the settlement and payment of the Final Base Purchase Price. Each of the Closing Payoff Amount, the Final Settlement Statement Payoff Amount and any other amounts paid to the Holders hereunder shall be allocated between the Holders in accordance with the Notes Allocation Ratio.

Issuer shall give notice to Holders in accordance with paragraph 8 hereof of the Closing and the Final Determination Date as soon as the same are known to Issuer.

2. Release of Issuer. Upon Holders’ receipt of the Payoff Discount, solely in accordance with the timing set forth in the second paragraph of paragraph 1 above, the Notes shall be deemed paid in full and Holders will be deemed to have released and discharged Issuer from any liability it might have to repay the Notes and from any of the other Obligations under the Notes and the other Note Documents (as such term is defined in the Notes) and Holders shall redeliver to Issuer the original Notes within two business days of the Holders’ receipt of their respective portions of the Payoff Discount, which Issuer may mark “paid in full.”

3. Notes Amendment.

If and only if the Closing Payoff Amount plus the Final Settlement Statement Payoff Amount plus the other payment(s) received by the Holders pursuant to the second paragraph in paragraph 1 hereof by the date that the Final Settlement Statement Payoff Amount is due under paragraph 1 is more than the Minimum Payoff Amount but less than the full amount of the Payoff Discount, (i) Holder Fund II-A and Issuer shall amend the Fund II-A Note in writing to reflect that, immediately after the payments on the date that the Final Settlement Statement Payoff Amount is due, the outstanding principal balance plus all accrued but unpaid interest on the Fund II-A Note shall be written down to an amount equal to $17,878,077.75 minus the amount of the aggregate payments received by Holder Fund II-A from Issuer pursuant to paragraph 1 hereof, (ii) Holder Fund II-B and Issuer shall amend the Fund II-B Note in writing to reflect that, immediately after the payment on the date that the Final Settlement Statement Payoff Amount is due, the outstanding principal balance plus all accrued but unpaid interest on the Fund II-B Note shall be written down to an amount equal to $3,621,922.25 minus the amount of the aggregate payments received by Holder Fund II-B from Issuer pursuant to paragraph 1 hereof and (iii) the amended principal balance of each Note shall constitute the new Tranche A Adjusted Principal Balance.

If the Closing Payoff Amount plus the Final Settlement Statement Payoff Amount plus the other payment(s) received by the Holders pursuant to the second paragraph in paragraph 1 hereof by the date that the Final Settlement Statement Payoff Amount is due under paragraph 1 is less than the Minimum Payoff Amount, then if and only if the Closing Payoff Amount plus the Final Settlement Statement Payoff Amount plus any Net Cash Proceeds from the first Contingent Payment under the Purchase Agreement (which shall be paid to Holders within three business days of when such amount is due and payable to Issuer, such date “First Contingent Payment Date”) plus the other payment(s) received by the Holders pursuant to the second paragraph in paragraph 1 hereof by the First Contingent Payment Date is more than the Minimum Payoff Amount, (i) Holder Fund II-A and Issuer shall amend the Fund II-A Note in writing to reflect that, immediately after the payments on the First Contingent Payment Date, the outstanding principal balance plus all accrued but unpaid interest on the Fund II-A Note shall be written down to an amount equal to $19,124,500.00 minus the amount of the aggregate payments received by Holder Fund II-A from Issuer in accordance with this Agreement, (ii) Holder Fund II-B and Issuer shall amend the Fund II-B Note in writing to reflect that, immediately after the payment on the First Contingent Payment Date, the outstanding principal balance plus all accrued but unpaid interest on the Fund II-B Note shall be written down to an amount equal to $3,875,500.00 minus the amount of the aggregate payments received by Holder Fund II-B from Issuer in accordance with this Agreement and (iii) the amended principal balance of each Note shall constitute the new Tranche A Adjusted Principal Balance.
