Executed Version 3396720.4 PROMISSORY NOTE (Revolving Line of Credit Note) $8,000,000.00 Odessa, Texas September 17, 2014 1. Borrower’s Promise to Pay. FOR VALUE RECEIVED, NAUTILUS POPLAR LLC, a Montana limited liability company (hereinafter called “Borrower”), whose principal address is 1775 Sherman Street, Suite 1950, Denver, Colorado 80203, promises to pay to the order of WEST TEXAS STATE BANK, (hereinafter called “Lender”) at its banking house in the City of Odessa, Ector County, Texas the principal sum of EIGHT MILLION DOLLARS ($8,000,000.00), or so much thereof as may be advanced hereunder prior to maturity, together with interest from date funded to Borrower until maturity on the unpaid principal balance thereof from time to time outstanding at the Stated Rate and with interest on all past due amounts, both principal and accrued interest, at the Past Due Rate, provided, that for the full term of this Note the interest rate produced by the aggregate of all sums paid or agreed to be paid to the holder of this Note for the use, forbearance or detention of the debt evidenced hereby shall not exceed the Ceiling Rate. 2. Loan Agreement. This Note and any substitutions, replacements, modifications, renewals and/or extensions thereof are described in and are subject to the terms and provisions of that certain Loan Agreement dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, “Loan Agreement”; terms used herein but not defined herein shall have the meanings given in the Loan Agreement) between Lender, Borrower and Magellan Petroleum Corporation (hereinafter called “Guarantor”). The Loan Agreement, among other things, contains provisions regarding the amount that the Lender is required to advance under the terms of this Note and provisions for the acceleration of the maturity hereof upon the happening or omission of certain stated events upon the terms and conditions therein specified and the payment of fees and expenses as set out in the Loan Agreement. 3. Interest. “Stated Rate” means, on any day, a rate per annum equal to the Index Rate from time to time in effect, provided that if on any day the Stated Rate shall (a) exceed the Ceiling Rate for that day, then the Stated Rate shall be fixed at the Ceiling Rate on that day and on each day thereafter until the total amount of interest accrued at the Stated Rate on the unpaid balance of this Note equals the total amount of interest which would have accrued if there were no Ceiling Rate and/or (b) be less than three and one-fourths percent (3.25%) (the “Floor Rate”), then the Floor Rate shall apply in lieu of the Stated Rate until such time that the Stated Rate exceeds or is equal to the Floor Rate. “Index Rate” for purposes of this Note shall mean the current rate of interest per annum as published in the Wall Street Journal as the Prime Rate in effect until the next Change Date. The Prime Rate may change and each change in the Prime Rate shall be effective on the date of publication of said change (referred to as “Change Date”) until the next Change Date. Each change in the Index Rate shall be effective without special notice to the Borrower or any other person or entity. The Index Rate is a reference rate and does not necessarily represent the lowest or best rate actually charged to any customer. If, for
any reason, the Index Rate is no longer available at the time of the change, the Lender will choose a new index based upon a reasonable comparable measure and reasonable comparable information and Lender will notify Borrower of the substitution of any such new index. Interest on the amount of each advance against this Note shall be computed on the amount of each advance and from the date of each advance. Interest shall be computed for the actual number of days elapsed and on the basis of a year consisting of 365 or 366 days, as the case may be. 4. Past Due Rate. At Lender’s option and without prior notice, upon and during the continuance of any default or Event of Default under this Note or any related Loan Documents, Lender may increase the interest rate applicable to this Note to a rate per annum equal to six percent (6.0%) above the Stated Rate (the “Past Due Rate”), not to exceed at any time the lesser of 18% or the Ceiling Rate, and said Past Due Rate shall remain in effect until the default or Event of Default has been cured and that fact has been communicated to and confirmed by Lender. Lender shall give written notice to Borrower of Lender’s imposition of the Past Due Rate. Lender’s imposition of the Past Due Rate shall not constitute an election of remedies or otherwise limit Lender’s rights concerning other remedies available to Lender as a result of the occurrence of an Event of Default. 5. Late Charges. If a payment is ten (10) days or more late, Borrower will be charged five percent (5.0%) of the amount of payment or $125.00, whichever is less. 6. Ceiling Rate. “Ceiling Rate” means, on any day, the maximum nonusurious rate of interest permitted for that day by whichever of applicable federal or Texas law permits the higher interest rate, stated as a rate per annum. On each day, if any, that Chapter 303 (“Chapter 303”) of the Texas Finance Code establishes the “Weekly Ceiling Rate”, the Ceiling Rate shall be the “indicated rate ceiling” as defined in Chapter 303 for that day. Lender may from time to time, as to current and future balances, implement any other ceiling under Chapters 302 or 303 of the Texas Finance Code by notice to Borrower, if and to the extent permitted by, Chapters 302 and 303. Without notice to the Borrower or any other person or entity, the Index Rate and the Ceiling Rate shall each automatically fluctuate upward and downward as and in the amount by which Lender’s Index Rate and the maximum nonusurious rate of interest, respectively, fluctuate. 7. Savings. If, for any reason whatever, the interest paid or received on this Note during the full term of this Note shall produce a rate which exceeds the Ceiling Rate, the holder of this Note shall refund to the Borrower or, at the holder’s option, credit against the principal of this Note such portion of said interest as shall be necessary to cause the interest paid on this Note to produce a rate equal to the Ceiling Rate. All sums paid or forbearance or detention of the indebtedness evidenced hereby shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread in equal parts
throughout the full term of this Note, so that the interest rate is uniform throughout the full term of this Note. If any word, phrase, clause, paragraph, part, portion or provision hereof is held to be invalid, the remainder hereof shall nevertheless be valid as though it had been entered into without such invalid word, phrase, clause, paragraph, part, portion or provision. 8. Payments. Principal and accrued interest shall be due and payable as follows: (a) Interest shall be due and payable quarterly as it accrues on the unpaid principal balance to the date of each installment, payment beginning December 31, 2014, and continuing on March 31, 2015 and June 30, 2015. (b) On September 30, 2015, the remaining balance, including outstanding principal and accrued but unpaid interest, then remaining unpaid on this Note shall be due and payable. This Note is a revolving line of credit promissory note having an original principal commitment amount of $8,000,000.00. The unpaid principal balance of this Note at any time shall be the total of all amounts loaned or advanced by the holder hereof less the amount of all payments or prepayments of principal made hereon by or for Borrower. Borrower may use all or any part of the credit provided for herein at any time before September 30, 2015. Borrower may borrow, repay and reborrow hereunder and there is no limitation on the number of advances made hereunder so long as the total unpaid principal balance, at any time outstanding, does not exceed $8,000,000.00. Unless otherwise agreed to, in writing, or otherwise required by applicable law, payments will be applied first to accrued, unpaid interest, and any remaining amount to any unpaid collection costs, late charges and other charges and the balance to the principal in inverse order of maturity, provided, however, during the continuance of an Event of Default, Lender reserves the right to apply payments among principal, interest, late charges, collection costs and other charges at its discretion. The Borrower may at any time pay the full amount or any part of this Note without the payment of any premium or fee. 9. Security.

Cost and Expenses. In addition to all outstanding principal and accrued but unpaid interest on this Note, the Borrower agrees to pay (a) all reasonable costs and expenses incurred by all owners and holders of this Note in any probate, reorganization, bankruptcy or any other proceedings for the establishment or collection or any amount hereunder, or in collecting this Note through any such proceedings, and (b) reasonable out-of-pocket attorney’s fees when and if this Note is placed in the hands of an attorney for collection during the continuance of an Event of Default, in each case except to the extent resulting from the gross negligence, willful misconduct or fraud of Lender. 12.
