(1) INTEREST. Indigo Natural Resources LLC, a Delaware limited liability company (the “Company”), promises to pay or cause to be paid interest on the unpaid principal amount of this Note at 5.375% per annum from [February 2, 2021]¹. The Company will pay interest, if any, semi-annually in arrears on February 1 and August 1 of each year, or if any such day is a Legal Holiday, on the next succeeding Business Day (each, an “Interest Payment Date”); provided that the first Interest Payment Date shall be August 1, 2021. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If any payment with respect to any principal of, premium, if any, on, or interest, if any, on any Note (including any payment to be made on any date fixed for redemption or purchase of any Note) is due on a day which is a Legal Holiday, then the payment need not be made on such date, but may be made on the next Business Day with the same force and effect as if made on such date, and no interest will accrue for the intervening period.

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders of Notes at the close of business on the January 15 and July 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office or agency of the Company maintained for such purpose described in the Indenture, or, at the option of the Company, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, on, and interest, if any, on, all Global Notes and all other Notes the Holders of at least $5 million principal amount of which will have provided wire transfer instructions to an account in the continental United States to the Company or the Paying Agent at least 30 days prior to the applicable payment date. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of a majority in aggregate principal amount of the then outstanding

Notes including Additional Notes, if any, voting as a single class, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class.

In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, then the principal of and accrued and unpaid interest on all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare the principal of and accrued and unpaid interest on the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest, if any) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of all the Holders, rescind an acceleration or waive an existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of principal of, premium, if any, on, or interest, if any, on, the Notes (including in connection with an offer to purchase any Notes).

No director, officer, employee, member, incorporator or stockholder or other owner of any Capital Stock of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture or the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Note Guarantees.
