PROMISSORYNOTE

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 the London Interbank Offered Rate Swaps (LIBOR SWAPS) for maturities of Five Years as published in the Wall Street Journal (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 Five Years. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 1.241% per annum. Interest on the unpaid principal balance of this Note will be calculated as described in the “INTEREST CALCULATION METHOD” paragraph using a rate of 3.500 percentage points over the Index, adjusted if necessary for any minimum and maximum rate limitations described below, resulting in an initial rate of 5.500%. NOTICE: Under no circumstances will the interest rate on this Note be less than 5.500% per annum or more than the maximum rate allowed by applicable law. Whenever increases occur in the interest rate, Lender, at its option, may do one or more of the following: (A) increase Borrower’s payments to ensure Borrower’s loan will pay off by its original final maturity date, (B) increase Borrower’s payments to cover accruing interest, (C) increase the number of Borrower’s payments, and (D) continue Borrower’s payments at the same amount and increase Borrower’s final payment.

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; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of this Note, Borrower understands that Lender is entitled to a minimum interest charge of $50.00. Other than Borrower’s obligation to pay any minimum interest charge, Borrower may pay without penalty 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 under the payment schedule. Rather, early payments will reduce the principal balance due and may result in Borrower’s making fewer payments. 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: US Employment Development Lending Center, LLC, 1 World Trade Center, Suite 1870 Long Beach, CA 90831.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. Upon default, the interest rate on this Note shall, if permitted under applicable law, Immediately increase by adding an additional 5.000 percentage point margin (“Default Rate Margin”).
