ARTICLE 2

TERMS OF FACILITY

2.1 Advances and Terms of Commitment . Subject to the terms and conditions hereinafter set forth, the Lender agrees to make Advances to the Borrowers from time to time until the final maturity date of the Note, in such amounts as the Borrowers may request up to an amount not to exceed, in the aggregate principal amount outstanding at any time, the lesser of (i) the Commitment or (ii) the Borrowing Base then in effect. The obligations of the Borrowers hereunder shall be evidenced by this Loan Agreement and the Note issued in connection herewith. Irrespective of the face amount of the Note, the Lender shall never have the obligation to Advance any amount or amounts in excess of the Commitment or to increase the Commitment.

2.2 Payments Under the Note . The aggregate unpaid amount of the Loan reflected by the notations by the Lender on its records shall be deemed rebuttably presumptive evidence of the principal amounts owing on the Note. The liability for payment of principal and interest evidenced by the Note shall be limited to principal amounts actually advanced and outstanding pursuant to this Loan Agreement, the Note and the other Loan Documents and interest accrued on such amounts calculated in accordance with this Loan Agreement and the Note.

2.3 Repayment Provisions . Interest, computed on the unpaid principal balance of the Note, shall be due and payable in monthly installments, with the first of such installments to be paid on January 28, 2019, and subsequent installments to be paid on the twenty-eighth day of each month thereafter. All of the outstanding principal and accrued, unpaid interest hereunder shall be due and payable in full on December 28, 2021 , being the date of final maturity hereunder. All payments of principal and interest required under the Note shall be made in immediately available funds, and shall be made at Lender’s principal banking offices in Midland, Texas, provided, however, the Lender may, upon thirty (30) day’s written notice to the Borrowers, designate a different place of payment. If a payment under the Note is received by the Lender more than ten (10) days after it is due, the Borrowers agree to pay a late charge to the Lender equal to five percent (5%) of the delinquent amount.

2.4 Interest Rates . The outstanding principal amount of the Note shall bear interest at the Applicable Rate, calculated on the basis of a year of three hundred sixty (360) days. Should default occur in the payment of the Note and collection proceedings be instituted, all past due interest and principal under the Note shall bear interest at the Default Rate, calculated on the basis of a year of three hundred sixty (360) days.

2.5 General Provisions Relating to Interest . It is the intention of the parties hereto to comply strictly with the applicable usury Laws as in effect from time to time; and in this connection, there shall never be taken, reserved, contracted for, collected, charged or received on any Loan or any other Obligations interest in excess of that which would accrue at the Highest Lawful Rate. For purposes of Chapter 303 of the Texas Finance Code, as amended, the Borrowers agree that the Highest Lawful Rate shall be the “weekly rate ceiling” as defined in such chapter, provided that the Lender may also rely, to the extent permitted by applicable Laws, on alternative maximum rates of interest under such other applicable Laws, if greater.

If under any circumstances the aggregate amount paid on the Obligations includes amounts that are by Law deemed to be interest which exceed the Highest Lawful Rate (the “ excess interest ”), the Borrowers and the Lender stipulate that such payment and collection will have been and will be deemed to have been, to the fullest extent permitted by applicable Laws, the result of mathematical error on the part of the Borrowers and the Lender, and the Lender shall promptly credit the amount of such excess interest on the principal amount of the outstanding Obligations, or if the principal amount of the Obligations shall have been paid in full, refund the excess interest to the Borrowers, as applicable. In the event that the maturity of the Note is accelerated by reason of an election of the Lender resulting from any Event of Default, or in the event of any prepayment, then such consideration that constitutes interest under Laws applicable to the Lender may never exceed the Highest Lawful Rate, and excess interest, if any, provided for in the Note, this Loan Agreement or otherwise shall be canceled automatically by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded by the Lender to the Borrowers, as applicable.

All sums paid, or agreed to be paid, to the Lender for the use, forbearance, and detention of the proceeds of the Loan shall, to the extent permitted by applicable Law, be amortized, prorated, allocated, and spread throughout the full term of the Obligations until paid in full so that the actual rate of interest is uniform, but does not exceed the Highest Lawful Rate, throughout the full term hereof.

2.6 Voluntary Prepayment . The Borrowers shall have the right and option to prepay, at any time without premium or penalty, all or any part of the Debt evidenced by the Note. Any such prepayments shall be applied first to the payment of accrued and unpaid interest thereon and then to the reduction of principal.

2.7 Borrowing Base .

(a) Borrowing Base Standards . The “Borrowing Base” shall represent the Lender’s determination, in its sole discretion, of the loan amount that may be supported by the Lender’s evaluation of the proved oil and gas properties of the Borrowers. The determination of the Borrowing Base will be made in accordance with then-current practices, economic and pricing parameters, methodology, assumptions, and customary procedures and standards established by the Lender from time to time for its petroleum industry customers, including, without limitation (i) an analysis of such reserve and production data with respect to all of the proved oil and gas properties of the Borrowers as is provided to the Lender in accordance herewith, (ii) an analysis of the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Borrowers, (iii) the Borrowers’ commodity hedging transactions, and (iv) such other credit factors consistently applied as the Lender customarily considers in evaluating similar oil and gas credit facilities. The Borrowers and the Lender acknowledge that due to the uncertainties of the oil and gas extraction process, the oil and gas properties of the Borrowers are not subject to evaluation with a high degree of accuracy and are subject to potential rapid deterioration in value, and that the determination of the loan amount will be less than the total present value of the proved oil and gas properties of the Borrowers, which the Borrowers’ acknowledge to be essential for the adequate protection of the Lender. Without limiting the foregoing, the Lender may exclude any oil and gas reserves or portion of production therefrom or any income from any property from the Borrowing Base, at any time, because title information is not satisfactory, such oil and gas reserves are not subject to a Bank Lien or such oil and gas reserves are not in “pay” status. Subject to any redetermination of the Borrowing Base pursuant to Section 2.7(b) or Section 2.7(c) , the initial Borrowing Base shall be $1,000,000.00 during the period from the date hereof to the date of the first redetermination of the Borrowing Base pursuant to Section 2.7(b) or Section 2.7(c) , and thereafter the amount of the Borrowing Base shall be the Borrowing Base most recently determined pursuant to Section 2.7(b) or Section 2.7(c) , as applicable.

(b) Periodic Redeterminations of Borrowing Base .

(i) The Borrowing Base shall be redetermined as of July 30 of each year until the final maturity date of the Note. On or before June 30 of each year, the Borrowers shall furnish the Lender an acceptable engineering report audited by an independent petroleum engineer acceptable to the Lender (and the Lender hereby approves Russell K. Hall & Associates as an acceptable independent petroleum engineer) as of the preceding March 31 covering all of the proved oil and gas properties of the Borrowers. Upon receipt of each such engineering report, the Lender shall make a determination of the Borrowing Base which shall become effective upon written notification from the Lender to the Borrowers, and which, subject to the other provisions of this Agreement, shall be the Borrowing Base until the effective date of the next redetermination as provided in this Section 2.7 .

(ii) In the event that the Borrowers do not furnish to the Lender an engineering report by the date specified in Section 2.7(b)(i) , then the Lender may nonetheless redetermine the Borrowing Base and redesignate the Borrowing Base from time to time thereafter in its sole discretion until the Lender receives the relevant engineering report, whereupon the Lender shall redetermine the Borrowing Base as otherwise specified in this Section 2.7 .

(c) Special Redeterminations of Borrowing Base . Special redeterminations of the Borrowing Base may be requested by the Lender at any time during the term hereof. If any special redetermination is requested by the Lender, the Borrowers will provide the Lender with engineering data for the oil and gas reserves updated from the most recent engineering report furnished to the Lender, as soon as is reasonably possible following the request, but in no event later than thirty (30) days after such request. The determination whether to increase or decrease the Borrowing Base shall be made in accordance with the standards set forth in Section 2.7(a) . ln the event of any special redetermination of the Borrowing Base pursuant to this Section, the Lender in the exercise of its discretion may suspend the next regularly scheduled redetermination of the Borrowing Base. Without limiting the foregoing, in the event the principal amount outstanding under the Note exceeds sixty-five percent (65.0%) of the lesser of (i) the Commitment or (ii) the Borrowing Base then in effect, at any time and from time to time (x) the Lender may request a redetermination of the Borrowing Base under this Section 2.7(c) , and (y) the Lender may require the Borrowing Base to be redetermined under Section 2.7(b) semi-annually as of July 30 and January 31 of each year until the earlier of (A) the final maturity date of the Note, or (B) such time that the principal amount outstanding under the Note is less than sixty-five percent (65.0%) of the lesser of (i) the Commitment or (ii) the Borrowing Base then in effect, in which case on or before June 30 and December 31 of each year, the Borrowers shall furnish the Lender an acceptable engineering report in accordance with Section 2.7(b) as of the preceding March 31 and the preceding September 30, respectively, covering all of the proved oil and gas properties of the Borrowers and the Lender will determine whether to increase or decrease the Borrowing Base in accordance with the standards set forth in Section 2.7(a) , and which redetermined Borrowing Base shall become effective upon written notification from the Lender to the Borrowers, and which, subject to the other provisions of this Agreement, shall be the Borrowing Base until the effective date of the next redetermination as provided in this Section 2.7 . Without limiting any other term or provision contained in this Loan Agreement, the Borrowers acknowledge and agree that in the event the Lender’s due diligence with respect to the Collateral, whether conducted before, on or subsequent to the date of this Loan Agreement, reveals any Liens, title issues, title defects or other matters affecting the Collateral which were not known to the Lender as of the execution date of this Loan Agreement, that the Lender may request a redetermination of the Borrowing Base under this Section 2.7(c) .

(d) Borrowing Base Deficiency .

(i) If the principal amount outstanding under the Note exceeds the amount of the Borrowing Base because of a periodic or special redetermination made pursuant to Section 2.7(b) or Section 2.7(c) , then the Lender shall send a Borrowing Base deficiency notice to the Borrowers, and the Borrowers shall within ten (10) days following receipt of such Borrowing Base deficiency notice elect by written notice to the Lender whether to (A) prepay an amount which would, if prepaid immediately, reduce the principal amount outstanding under the Note to the amount of the Borrowing Base, (B) execute one or more mortgages or deeds of trust, in form and substance satisfactory to the Lender, covering such other oil and gas properties not previously taken into account in the redetermination of the Borrowing Base as are acceptable to the Lender having present values which, in the opinion of the Lender, based upon the Lender’s evaluation of the engineering data provided it, taken in the aggregate are sufficient to increase the Borrowing Base to an amount at least equal to the principal amount outstanding under the Note, or (C) do any combination of the foregoing as is acceptable to the Lender. If the Borrowers fail to deliver their written election to the Lender within ten (10) days after the Borrowers’ receipt of the Borrowing Base deficiency notice, then the Borrowers shall be deemed to have selected the prepayment option specified in clause (A) above.

(ii) The Borrowers shall deliver such prepayments or mortgages or deeds of trust of additional oil and gas properties in accordance with their election (or deemed election) pursuant to Section 2.7(d)(i) as follows:

(A) Prepayment Elections . If the Borrowers elect (or are deemed to have elected) to prepay an amount in accordance with Section 2.7(d)(i)(A) above, then the Borrowers may make such prepayment in one installment within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice or, provided no Event of Default has occurred and is continuing hereunder, in three (3) equal consecutive monthly installments beginning within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice and continuing on the same day of each month thereafter.

(B) Elections to Mortgage Additional Oil and Gas Properties . If the Borrowers elect to mortgage additional oil and gas properties in accordance with Section 2.7(d)(i)(B) above, then (1) such properties must be acceptable to the Lender with values determined by the Lender in accordance with this Section 2.7 and (2) the applicable Borrower(s) shall execute, acknowledge and deliver to the Lender one or more mortgages or deeds of trust, in form and substance satisfactory to the Lender, within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice (or such longer time as determined by the Lender); provided, however (x) if the additional oil and gas properties offered by the Borrowers are not acceptable to the Lender, the Borrowers shall be deemed to have elected the prepayment option specified in Section 2.7(d)(i)(A) (and the Borrowers shall make such prepayment in accordance with Section 2.7(d)(ii)(A) ); and (y) if the aggregate present values of additional oil and gas properties which are acceptable to the Lender are insufficient to eliminate the Borrowing Base deficiency, then the Borrowers shall be deemed to have selected the option specified in Section 2.7(d)(i)(C) (and the Borrowers shall make prepayment and deliver one or more mortgages or deeds of trust as provided in Section 2.7(d)(ii)(C) ). Together with such mortgages and deeds of trust, the Borrowers shall deliver to the Lender title opinions and/or other title information and data acceptable to the Lender.

(C) Combination Elections . If the Borrowers elect (or are deemed to have elected) to eliminate the Borrowing Base deficiency by a combination of prepayment and mortgaging of additional oil and gas properties in accordance with Section 2.7(d)(i)(C) , then within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice (or such longer time as determined by the Lender), the applicable Borrower(s) shall execute, acknowledge and deliver to the Lender one or more mortgages or deeds of trust, in form and substance satisfactory to the Lender, covering such additional oil and gas properties and pay the Lender the amount by which the Borrowing Base deficiency exceeds the present values of such additional oil and gas properties in one installment within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice or, provided no Event of Default has occurred and is continuing hereunder, in three (3) equal consecutive monthly installments beginning within thirty (30) days after the Borrowers’ receipt of the Borrowing Base deficiency notice and continuing on the same day of each month thereafter.

2.8 Unused Commitment Fee . The Borrowers shall pay to the Lender an unused commitment fee (the “ Unused Commitment Fee ”) in an amount equal to one half of one percent (.50%) times the daily average of the unadvanced amount of the Available Commitment. As used herein, “ Available Commitment ” means an amount equal to the lesser of (i) the Commitment or (ii) the Borrowing Base then in effect. Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days. The Unused Commitment Fee shall be payable quarterly in arrears on the last day of each calendar quarter beginning March 31, 2019, with the first payment being for the period from the date of this Agreement through March 31, 2019, and with the final fee payment due on the maturity date of the Note for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid.

For value received, MEXCO ENERGY CORPORATION , a Colorado corporation ( “Mexco” ), FORMAN ENERGY CORPORATION , a New York corporation (“ Forman ”), SOUTHWEST TEXAS DISPOSAL CORPORATION , a Texas corporation (“ Southwest ”), and TBO OIL & GAS, LLC , a Texas limited liability company (“ TBO ”, and together with Mexco, Forman and Southwest, collectively, the “ Makers ” or individually a “ Maker ”), jointly and severally, promise to pay to the order of WEST TEXAS NATIONAL BANK , a national bank (the “ Lender ”), at its offices at 6 Desta Dr., Suite 2400, Midland, Texas 79705, in lawful money of the United States of America, the principal sum of ONE MILLION AND NO/100 DOLLARS ($1,000,000.00) , or so much thereof as may be advanced and outstanding at any time or from time to time pursuant to the Loan Agreement (as hereinafter defined), together with interest on the principal amount from time to time outstanding hereunder, from the date of the disbursement of such principal until maturity, at an annual rate of interest which shall from day to day be equal to the lesser of (a) the Wall Street Journal Prime Rate in effect on such date (calculated on the basis of actual days elapsed, but computed as if each calendar year consisted of 360 days), plus one half of one percent (0.50%), or (b) the Highest Lawful Rate; provided, however, all past due principal and interest on this Note will bear interest from the maturity thereof until paid, at the Default Rate, as defined in the Loan Agreement.

2. This Note is executed pursuant to the terms of that certain Loan Agreement, dated of even date herewith (the “ Loan Agreement ”), by and among the Makers, as borrowers, and Lender, as lender. This Note incorporates by reference the terms of the Loan Agreement. In the event of a conflict between the terms of this Note and the terms of the Loan Agreement, the terms of the Loan Agreement will be deemed to be controlling. Capitalized terms not defined in this Note shall have the meaning given to such terms in the Loan Agreement. This is a Revolving Line of Credit Promissory Note. Accordingly, it is contemplated that there will be Advances and payments on this Note from time to time, but no Advances or payments (including total payment of the unpaid principal balance outstanding prior to maturity) shall affect or impair the validity or enforceability of this Note as to future Advances hereunder. Notwithstanding the face amount of this Note, in no event shall the outstanding principal amount of all Advances made hereunder at any time exceed the lesser of (i) the Commitment or (ii) the Borrowing Base then in effect. Reference is made to the Loan Agreement for further statements regarding the obligation of Lender to make Advances hereunder.

3. Interest, computed on the unpaid principal balance of this Note, shall be due and payable in monthly installments, with the first of such installments to be paid on January ___, 2019, and subsequent installments to be paid on the __________ day of each month thereafter. All of the outstanding principal and accrued, unpaid interest hereunder shall be due and payable in full on December ___, 2021, being the date of final maturity hereunder. All payments of principal and interest required under this Note shall be made in immediately available funds, and shall be made at Lender’s principal banking offices in Midland, Texas, provided, however, the Lender may, upon thirty (30) day’s written notice to the Makers, designate a different place of payment. If a payment under this Note is received by the Lender more than ten (10) days after it is due, the Makers agree to pay a late charge to the Lender equal to five percent (5%) of the delinquent amount.

4. If an Event of Default should occur under the terms of the Loan Agreement, thereupon at the option of Lender, the principal balance and accrued interest of this Note will become and be due and payable forthwith without presentment, demand, notice of default, protest, notice of protest or dishonor, notice of nonpayment, notice of acceleration or the intent to accelerate, or other notice of any kind, all of which are hereby expressly waived by each Maker and each other liable party. Lender may waive any default without waiving any prior or subsequent default.

5. To the extent not prohibited by applicable Law, Makers will pay all costs and expenses and reimburse Lender for any and all expenditures of every character incurred or expended from time to time, regardless of whether a default or Event of Default will have occurred, in connection with Lender exercising any of its rights and remedies under this or any other instrument now or hereafter securing the indebtedness evidenced hereby or at Law, including, without limitation, all filing fees, taxes, brokerage fees and commissions, title review and abstract fees, Uniform Commercial Code search fees, other fees and expenses incident to title searches, reports and security interests, escrow fees, attorneys’ fees, legal expenses, and court costs, provided, however, that no right or option granted by Makers or Lender or otherwise arising pursuant to any provision of this or any other instrument will be deemed to impose or admit a duty on Lender to supervise, monitor or control any aspect of the character or condition of the assets of Makers or any operations conducted in connection with it for the benefit of any Maker or any other person or entity other than Lender.

6. If this Note is not paid at maturity whether by acceleration or otherwise and is placed in the hands of an attorney for collection, or suit is filed hereon, or proceedings are had in probate, bankruptcy, receivership, reorganization, arrangement or other legal proceedings for collection hereof, Makers and each other liable party agree to pay Lender its collection costs, including a reasonable amount for attorneys’ fees, but in no event to exceed the maximum amount permitted by Law. Each Maker and each other liable party are and will be directly and primarily, jointly and severally, liable for the payment of all sums called for hereunder, and each Maker and each other liable party hereby expressly waive bringing of suit and diligence in taking any action to collect any sums owing hereon and in the handling of any security, and each Maker and each other liable party hereby consent to and agree to remain liable hereon regardless of any renewals, extensions for any period or rearrangements hereof, or partial prepayments hereon, or any release or substitution of security hereof, in whole or in part, with or without notice, from time to time, before or after maturity.

7. It is the intention of the parties hereto to comply strictly with the applicable usury Laws as in effect from time to time; and in this connection, there shall never be taken, reserved, contracted for, collected, charged or received on this Note or any other Obligations interest in excess of that which would accrue at the Highest Lawful Rate. For purposes of Chapter 303 of the Texas Finance Code, as amended, the Makers agree that the Highest Lawful Rate shall be the “weekly rate ceiling” as defined in such chapter, provided that the Lender may also rely, to the extent permitted by applicable Laws, on alternative maximum rates of interest under such other applicable Laws, if greater.

If under any circumstances the aggregate amount paid on the Obligations includes amounts that are by Law deemed to be interest which exceed the Highest Lawful Rate (the “ Excess Interest ”), the Makers and the Lender stipulate that such payment and collection will have been and will be deemed to have been, to the fullest extent permitted by applicable Laws, the result of mathematical error on the part of the Makers and the Lender, and the Lender shall promptly credit the amount of such Excess Interest on the principal amount of the outstanding Obligations, or if the principal amount of the Obligations shall have been paid in full, refund the Excess Interest to the Makers. In the event that the maturity of this Note is accelerated by reason of an election of the Lender resulting from any Event of Default, or in the event of any prepayment, then such consideration that constitutes interest under Laws applicable to the Lender may never exceed the Highest Lawful Rate, and Excess Interest, if any, provided for in this Note, the Loan Agreement or otherwise shall be canceled automatically by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded by the Lender to the Makers.

All sums paid, or agreed to be paid, to the Lender for the use, forbearance, and detention of the proceeds of the Loan shall, to the extent permitted by applicable Law, be amortized, prorated, allocated, and spread throughout the full term of the Obligations until paid in full so that the actual rate of interest is uniform, but does not exceed the Highest Lawful Rate, throughout the full term hereof.

8. Makers reserve the option of prepaying the principal of this Note, in whole or in part, at any time after the date hereof without penalty. At the option of Lender, it may demand (at any time at or after prepayment) all accrued and unpaid interest with respect to the principal amount prepaid through the date of prepayment. All amounts of principal so prepaid and received by the owner and holder of this Note will be applied to the last maturing installments of this Note in their inverse order of maturity.

9. This Note is secured by the Security Documents described in the Loan Agreement.

10. Lender reserves the right, exercisable in Lender’s sole discretion and without notice to Makers or any other person, to sell participations, to assign its interest or both, in all or any part of this Note or the debt evidenced by this Note.

11. This Note shall be governed by and construed in accordance with the Laws of the United States of America and the State of Texas, except to the extent the location or nature of the collateral securing this Note requires the application of the Laws of other jurisdictions to be applied as to matters of creation, perfection and priority of liens and the rights of Lender upon default.

12. By execution of this Note, each Maker acknowledges the receipt of the following notices from Lender:

“THE LOAN AGREEMENT, THIS NOTE, AND ALL OTHER LOAN DOCUMENTS EXECUTED HEREWITH TOGETHER CONSTITUTE A WRITTEN LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.”
