(Line of Credit)

Exhibit 10.3       PROMISSORY NOTE AND LOAN AGREEMENT

 (Line of Credit)

FOR VALUE RECEIVED Flexpoint Sensor Systems, Inc. (“Maker”), promises to Maestro Investments, LLC (“Holder”), as follows:

1.     Principal and Interest.   Holder agrees to provide Maker with a line of credit in an amount up to Five Hundred Thousand Dollars ($500,000.00) subject to and upon the terms and conditions of this Note.  So long as there is no Event of Default as defined herein, Holder agrees to make advances on this Line of Credit to Maker (“Advances”)  from time to time as agreed upon by both Maker and Holder commencing from the date of this Promissory Note (“Note”) up to the maturity Date, as defined herein.  Notwithstanding anything to the contrary in this Note, the aggregate principal amount of the Note shall not at any time exceed Five Hundred Thousand Dollars ($500,000.00).   Maker promises to pay to the order of Holder at 455 E 400 S, Salt Lake City, UT 84111, in legal tender of the United States of America, the sum of all Advances under the Note (“Principal”) together with Base Interest thereon at a fixed rate of interest of twelve percent (12%) per annum (“Base Interest”) on that part of the Principal that has been advanced and has not been paid.  Base Interest will be charged on all Advances beginning on the date of funding of this Note, and continuing until the full amount of Principal, accrued Base Interest and any additional charges under this Note have been paid.  Interest shall be calculated at the rate set forth above on the basis of a 360 day year and the actual number of days elapsed by multiplying the principal sum by the per annum rate set forth above and multiplying the product thereof by the actual number of days elapsed and dividing the product so obtained by 360.  “Date of Funding” shall mean that date on which the Maker receives the first Loan Advance from Lender.

2.        Alternate Rate of Interest.  In the event of a default and beginning at the time of default in the terms of this Note or any other document given in connection with this loan (collectively, the “Loan Documents”), or Maker’s failure to pay an installment of Base Interest or the Principal on the date on which it is due, then the entire amount of unpaid Principal and Base Interest on this Note shall bear interest at the rate of Eighteen percent (18 %) per annum (the “Alternate Rate”).

3.        Late Fee.  In the event a scheduled payment is not received by holder on its due date, Maker shall be assessed a late fee of three percent (3%) of the payment due.  This payment shall be made to compensate Holder for additional risk and expense involved in managing and servicing a delinquent loan.  Each payment shall be first credited to any late payments due, then to accrued interest due, and the remaining to principal.

4.       Repayment.  Maker shall pay the  entire  Principal balance, together with accrued and unpaid Base Interest, if any, and other charges permitted under this Note or the Loan Documents, on or before December 31, 2012 (the “Maturity Date”).  All payments received shall be applied first to Base Interest, second, as applicable, to any prepayment charge under this Note, third to interest at the Alternate Rate, if applicable, and fourth to Principal.
