PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on December 31, 2013. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning April 1, 2013, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied to the loan in the following order: (1) interest; (2) principal; and (3) charges, fees and penalties. Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the London Interbank Rate as hereinafter defined

"Business Day" shall mean a day of the year on which banks are not required or authorized to close in Dallas, Texas and, in connection with determining the London Interbank Rate, dealings are carried on in the London interbank market and banks are open for London.

"London Interbank Rate" shall mean, with respect to each LIBOR Interest Period, as defined below, the interest rate per annum (rounded upward to the nearest whole multiple of 1/32 of 1%) recorded in The Wall Street Journal on the date which is two (2) Business days before the first day of such LIBOR Interest Period, for U.S. Dollar deposits in the London interbank market for a length of time approximately equal to the LIBOR Interest Period and in amounts comparable to the outstanding balance of the Note. In the event The Wall Street Journal shall cease to be published or record LIBOR rates, then a comparable financial publication selected by Lender in its sole discretion shall instead be used for such information. In the event such rate is unavailable, the London Interbank Rate shall mean, with respect to each LIBOR Interest Period, the rate per annum determined by Lender in its sole discretion to be the arithmetic average (rounded upward to the nearest whole multiple of 1/32 of 1%) of the respective rates communicated to it by prime banks in the London interbank market at approximately 11:00 a.m. London time on the date two (2) Business Days prior to the first day of such LIBOR Interest Period on the offering by such prime banks in the London interbank market of deposits of U.S. Dollars for a period of time approximately equal to such LIBOR Interest Period and in amounts comparable to the outstanding balance of the Note. (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans. If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each "LIBOR Interest Period".

"LIBOR Interest Period" shall mean the period beginning on i) the Note date and ending one month ("One Month LIBOR") thereafter, and ii) thereafter the period beginning on the first day after the end of the immediately preceding LIBOR Interest Period and ending one month thereafter; provided however, that if the last day of such LIBOR Interest Period would otherwise occur on a day which is not a Business Day, such last day shall be extended to the next succeeding Business Day, except if such extension would cause such last day to occur in a new calendar month, in which event such last day shall occur on the next preceding Business Day. Borrower understands that Lender may make loans based on other rates as well. Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 1.750 percentage points over the Index. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method.

PREPAYMENT. Borrower may pay without fee all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due.

PREPAYMENT. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes "payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: Citibank, N.A.; 6801 Colwell Boulevard; Irving, TX 75039.

LATE CHARGE. If a payment is 15 days or more late, Borrower will be charged 4.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. If any Event of Default shall occur, including failure to pay upon final maturity, Lender, at its option, may, if permitted under applicable law, increase the interest rate on this Note to 4.750 percentage points above the index. The interest rate will not exceed the maximum rate permitted by applicable law.
