Form of Pay-Off Letter Agreement

Reference is made to the obligations and amounts outstanding with respect to that certain Convertible Promissory Note (the “Note”) issued to you by Duos Technologies Group, Inc., a Florida corporation (the “Company”) dated November 1, 2015 in the amount of $_____________. Under the terms and conditions of the Note, you are owed $________, including interest though October 16, 2017 (the “Debt Obligation”).

As described in the Second Amended Letter Agreement dated on or about July 27, 2017, the Company was in the process of pursuing a public offering of its securities to raise at a minimum $5,000,000 and remain quoted on the OTC Markets OTCQB (the “Initial Offering”). On September 28, 2017, the Company entered into a Non-Binding Letter of Intent to consummate a Preferred Share and Warrant Financing in an amount up to $15,000,000 (the “Current Offering”). Therefore, the Company is contacting you and other holders of the Company’s securities to inform you of such changes to the Initial Offering and provide payment to you for the Debt Obligation pursuant to the terms and conditions of the Current Offering as further described herein (the “Pay-Off”).

Upon delivery of payment to you in the amount of the Debt Obligation, the Company will have paid all amounts due and owing to you under the Note. Further, effective immediately upon your receipt of payment in full in cash of the Debt Obligation, without further action on the part of the parties hereto, all obligations of the Company to you, under the Note, shall be paid and discharged in full.

By signing below, this Pay-Off Letter Agreement shall serve as written confirmation that you have reviewed this Pay-Off Letter Agreement (and consulted with your legal and tax advisors to the extent you deemed necessary) and agree to the terms and conditions of the Pay-Off as described herein. Upon the Effective Date of such Pay-Off, you understand that you will be releasing and discharging the Company and its affiliates from any and all obligations and duties that such persons may have to you with respect to the Note and the Debt Obligation. Notwithstanding anything contained herein, in the event the Current Offering is not consummated on or before ninety (90) days from the date hereof, this Pay-Off Letter Agreement will terminate and shall be of no further force and effect.
