COMMERCIAL PROMISSORY NOTE

FOR VALUE RECEIVED, Borrower, jointly and severally if more than one, promises to pay to the order of Lender (which term shall include all subsequent holders of this Note) at its offices set forth above or at such other address as Lender may from time to time designate, in lawful money of the United States of America, the principal sum of Twelve Million One Hundred Eighty-Seven Thousand Five Hundred and 00/100 Dollars ($12,187,500.00), or so much thereof as may be advanced and outstanding from time to time, with interest at the rate provided below on the principal balance from time to time remaining unpaid, in the amounts, at the times and upon the terms provided in this Note. This Note is performable in Bryan County, Oklahoma.

INTEREST RATE. Interest shall accrue on the unpaid balance of this Note from time to time outstanding which is not past due, calculated on a 360-day annual basis (the “Rate”), except as otherwise provided herein, as follows:

For the period from the date hereof until June 28, 2013 the Rate shall be fixed at three and one-quarter percent (3.25%) per annum.

Thereafter, beginning June 28, 2013, Rate shall be the lesser of (a) the Loan Rate (hereinafter defined) or (b) the Highest Lawful Rate (hereinafter defined). The term “Loan Rate” shall mean the Index as hereafter defined. The Loan Rate shall be subject to change daily with changes in the Index.

Any change in either the Loan Rate or the Highest Lawful Rate shall, after Lender gives only such notice as may be required by applicable law or regulation, be effective for purposes of determining the Rate as of the opening of business on the date of any such change.

The Index is The Wall Street Journal Prime Rate which is the highest rate shown as the base rate on corporate loans posted by at least 75% of the nation’s 30 largest banks as published daily in the Money Rates Section of the Wall Street Journal.

Loan No.                                 

The “Highest Lawful Rate” is the maximum lawful rate which may be contracted for, charged, taken, received, or reserved by Lender in accordance with the applicable laws of the State of Texas (or applicable United States federal law to the extent that it permits Lender to contract for, charge, take, receive or reserve a greater amount of interest than under Texas law), taking into account all charges made in connection with this loan which are treated as interest under applicable law.

If at any time (i) the Loan Rate, (ii) interest on matured unpaid amounts, if applicable, as provided for herein or in any of the other Loan Documents, together with (iii) all fees and charges, if any, contracted for, charged, received, taken or reserved by Lender in connection with the loan evidenced hereby which are treated as interest under applicable law (collectively, the “Charges”), computed over the full term of this Note, exceed the Highest Lawful Rate, the rate of interest payable hereunder, together with all Charges, shall be limited to the Highest Lawful Rate; provided, however, that any subsequent reduction in the Loan Rate shall not cause a reduction of the rate of interest payable hereunder below the Highest Lawful Rate until the total amount of interest earned hereunder, together with all Charges, equals the total amount of interest which would have accrued at the Loan Rate if such interest rate had at all times been in effect. Changes in the Loan Rate resulting from a change in the Index shall be subject to the provisions of this paragraph.

PREPAYMENT. Borrower may prepay this Note in whole or in part at any time without being required to pay any penalty or premium for such privilege. In the event a prepayment is made, such payment shall be applied first against accrued but unpaid interest, then to the discharge of any expenses for which the holder of this Note may be entitled to receive reimbursement under the terms of this Note or under the terms of any other documents related thereto and lastly against the principal hereof. Any partial prepayment shall not postpone the due date or change the amount of any subsequent installment due hereunder.

PAST DUE PAYMENTS. Lender may charge and collect a late fee of up to five percent (5%) of the unpaid portion of the regularly scheduled payment more than 15 days past due to the extent not prohibited by law. The annual interest rate on matured unpaid amounts shall be eighteen percent (18%).

DISHONORED CHECK CHARGE. Lender may charge and collect a processing fee of up to $25.00 for each check given by Borrower to Lender as a payment on this loan which is dishonored.

PAYMENT TERMS. This Note shall be due and payable as follows:

Interest only, shall be due and payable quarterly as it accrues, on the 28th day of March, June, September and December of each and every calendar year, beginning September 28, 2011, and continuing regularly and quarterly thereafter until June 28, 2015, when the entire amount of principal and interest remaining unpaid, shall be then due and payable.

IF BORROWER REFINANCES THIS LOAN AT MATURITY, BORROWER WILL HAVE TO PAY SOME OR ALL OF THE CLOSING COSTS NORMALLY ASSOCIATED WITH A NEW LOAN EVEN IF BORROWER OBTAINS REFINANCING FROM THE SAME LENDER. THIS LENDER WILL CONSIDER AN APPLICATION TO REFINANCE THE BALLOON PAYMENT AT THE TIME PAYMENT IS DUE, ON THE SAME BASIS AS ALL OTHER NEW MORTGAGE LOAN APPLICATIONS.

4. The filing of a petition, case, proceeding, or other action against Borrower, or any Guarantor, as a debtor under any debtor relief law; or seeking appointment of a receiver, trustee, or custodian of Borrower, or any Guarantor, or of any property described in the Loan Documents or any part thereof, or of any significant portion of other property belonging to Borrower or any Guarantor, that affects its ability to perform under this Note, or seeking to effect a suspension or having the effect of suspending any of the rights of Lender or the Trustee granted or referred to in the Loan Documents, and: (a) Borrower or any Guarantor admits, acquiesces in, or fails to contest the material allegations thereof; or (b) the petition, case, proceeding, or other action results in entry of an order for relief or order granting the relief sought against Borrower or any Guarantor; or (c) the petition, case, proceeding, or other action is not permanently dismissed on or before the earlier of trial thereon or sixty (60) days next following the date of its filing.

5. The discovery by Lender that any warranty, covenant, or representation made to Lender by or on behalf of Borrower or any Guarantor is false, misleading, erroneous, or breached in any material respect.

A default shall not be an Event of Default, if a monetary default is cured within ten (10) days and a non-monetary default is cured within thirty (30) days following the delivery of or the mailing of written notice from Lender to Borrower’s most current address as reflected in Lender’s business records specifying the existence of any such default. If such default is not cured within the applicable period, the default shall be an Event of Default without need of any further notice or action by Lender. Notwithstanding the foregoing, if a non-monetary default is not capable of being cured within the thirty (30) day period referenced herein, it shall not be considered an Event of Default so long as Borrower is using diligent efforts to cure said non-monetary default.

ACCELERATION AND WAIVER OF NOTICE. Upon the occurrence of an Event of Default, the entire unpaid principal balance plus all accrued and unpaid interest due and owing on this Note and any and all other indebtedness of Borrower to Lender shall, at the option of Lender, become and be due and payable forthwith without demand, notice of default, notice of intent to accelerate, or the acceleration of the maturity hereof, notice of nonpayment, presentment, protest, or notice of dishonor, all of which are hereby expressly waived to the full extent not prohibited by law by Borrower and each other liable party. Failure to exercise this option upon the occurrence of any such Event of Default shall not constitute a waiver of the right to exercise such option in the event of any subsequent Event of Default.

COLLECTION COSTS AND JOINT AND SEVERAL LIABILITY. If the unpaid principal balance plus all accrued and unpaid interest due and owing on this Note is not paid at maturity, whether by acceleration or otherwise, and this Note 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, Borrower and each other liable party agree to pay Lender its reasonable collection costs, including a reasonable amount for attorneys’ fees. Borrower and each other liable party is and shall be directly and primarily, jointly and severally, liable for the payment of all sums due hereunder, under the Loan Documents and under any instrument securing the payment hereof,

and Borrower and each other liable party hereby expressly waives bringing of suit and diligence in taking any action to collect any sums owing hereon and in the handling of any security, and Borrower and each other liable party hereby consents to and agrees to remain liable hereon regardless of any renewals, extensions for any period or rearrangements hereof, 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.

LOAN CHARGES. It is expressly stipulated and agreed to be the intent of Borrower and Lender at all times to comply with the applicable Texas law governing the maximum rate or amount of interest payable on this Note or the indebtedness evidenced hereby and by the other Loan Documents (or applicable United States federal law to the extent that it permits the Borrower to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever judicially interpreted so as to render usurious any amount called for under this Note or under any of the Loan Documents, or contracted for, charged, taken, reserved or received with respect to such indebtedness, or if Borrower’s exercise of the option herein contained to accelerate the maturity of this Note or if any prepayment by Borrower results in Borrower having paid any interest in excess of that permitted by applicable law, then it is Borrower’s and Lender’s express intent that all excess amounts theretofore collected by Lender be credited on the principal balance of this Note (or, if this Note has been or would thereby be paid in full, refunded to Borrower), and the provisions of this Note and the other Loan Documents immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Lender to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration. All sums paid or agreed to be paid by Lender for the use, forbearance or detention of the indebtedness evidenced hereby and by the other Loan Documents shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness evidenced hereby for so long as debt is outstanding. To the extent that Lender is relying on the Texas Finance Code, as amended, to determine the Highest Lawful Rate payable on such indebtedness, Lender will utilize the indicated (weekly) rate ceiling from time to time in effect. To the extent United States federal law permits Lender to contract for, charge or receive a greater amount of interest, Lender will rely on United States federal law instead of the Texas Finance Code, as amended, for the purpose of determining the Highest Lawful Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, Lender may, at its option and from time to time, implement any other method of computing the Highest Lawful Rate under any other applicable law by giving notice, if required, to Borrower as provided by applicable law now or hereafter in effect.
