PROMISSORY NOTE

Exhibit 10.26

PROMISSORY NOTE

PROMISE TO PAY. Superior Drilling Products of California, LLC (“Borrower”) promises to pay to US Employment Development Lending Center, LLC (“Lender”), or order, in lawful money of the United States of America, the principal amount of Four Hundred Sixty-one Thousand Five Hundred & 00/100 Dollars ($461,500.00), together with interest on the unpaid principal balance from April 2, 2012, until paid in full.

PAYMENT. Borrower will pay this loan in one principal payment of $461,500.00 plus interest on October 1, 2012. This payment due on October 1, 2012, will be for all principal and all accrued interest not yet paid. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning May 1, 2012, 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 first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs. 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 prime rate 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 day. Borrower understands that Lender may make loans based on other rates as well. The index currently is 3.250% 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 3.000 percentage points over the index, adjusted if necessary for any minimum and maximum rate limitations described below, resulting in an initial rate of 6.250%. NOTICE: Under no circumstances will the interest rate on this Note be less than 6.250% per annum or more than the maximum rate allowed by applicable law.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 30/360 simple interest basis; that is, with the exception of odd days before the first full payment cycle, monthly interest is calculated by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by a month of 30 days. Interest for the odd days before the first full month is calculated on the basis of the actual days and a 360-day year. All interest payable under this Note is computed using this method.

JOB CREATION INTEREST RATE PROVISION. Notwithstanding anything contained in this Note to the contrary: (i) if, on the first anniversary of the date of this Note, the total number of employees employed by Borrower has increased over the number of employees employed by Borrower as of the date of this Note by less than five (5) full time positions, or if, during the first twelve (12) months of the term of this Note, Borrower fails to provide such reports and documentation required by Lender to evidence and report the results of any job creation by Borrower, then the Interest Rate shall automatically increase, without notice, during the calendar year form the first anniversary of this Note to the second anniversary of this Note to a rate equal to the “Wall Street Journal Prime” (as defined herein) plus six percent (6.00%); and (ii) if, on the second anniversary of the date of this Note, the number of employees employed by Borrower has increased by less than (12) full-time positions, of if, during the second twelve (12) months of the term of this Note, Borrower fails to provide such reports and documentation required by Lender to evidence and report the results of any job creation by Borrower, or if, Borrower fails to sustain a minimum of twelve new (12) full-time positions over the number of employees employed by Borrower as of the time of this Note at all times during the period between the second and third anniversary of this Note, then the interest Rate shall be increased for the remaining term of the Loan to a rate equal to the Wall street Journal Prime plus six percent (6.00%). For purposes of this provision: (i) the term “full-time position” shall refer to an employee of Borrower who regularly works at least thirty-five (35) hours in a workweek and is compensated by wages paid by Borrower and reported for federal tax purposes on IRS Form W-2, and (ii) Borrower and Lender acknowledge that, as of the date of this Note, the number of employees currently employed by Borrower in connection with its business is 24. The term “Wall Street Journal Prime” shall mean the rate from time to time published in the Wall Street Journal and referred to therein as “Prime Rate,” provided that if the Prime Rate should cease to be published in the Wall Street Journal, or if the Wall Street Journal should cease to be published, then Lender shall select an alternate base rate (for purposes of this provision) that, in the judgment of Lendor is likely to result in a base rate being substantially similar to the Prime Rate previously published.

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 penally 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. 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”). The Default Rate Margin shall also apply to each succeeding interest rate change that would have applied had there been no default.

However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.
