Gentlemen:

Reference is made to that certain Loan Agreement, dated as of July 31, 2018, among Victory Oilfield Tech, Inc., a Delaware corporation ("Borrower"), and Kodak Brothers Real Estate Cash Flow Fund, LLC, a Texas limited liability company ("Lender") (as it may be further amended, restated, supplemented or otherwise modified through the date hereof, the "Loan Agreement"), regarding a loan made by Lender to Borrower in the original principal amount of $375,000. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Loan Agreement.

The Note referenced in the Loan Agreement provided for an initial Maturity Date of March 31, 2019. Borrower, as Maker under the Note, subsequently exercised the Term Option referenced in Section l(a) of the Note, thereby extending the Maturity Date until June 30, 2019. Lender and Borrower subsequently executed that certain Extension and Modification Agreement dated July 10, 2019 (the "First EMA"), extending the Maturity Date to September 30, 2019, increasing the Base Rate of interest applicable to the Loan and containing other revisions to the Loan and Note as set forth therein.

Lender and Borrower now wish to extend and modify the terms of the Loan contemplated by the Loan Agreement as set forth in this letter agreement.

Lender and Borrower, by execution of this letter agreement (this "Second Extension and Modification Agreement") hereby agree as follows, with such agreement to be effective as of September 30, 2019 (the "Effective Date"):

1. Extension. The Maturity Date set forth in the First EMA is hereby extended from September 30, 2019 to December 30, 2019. Accordingly, all references to the "Maturity Date" contained in the Loan Documents are hereby deemed amended to reference December 30, 2019. Such extension is effective for all purposes under the Loan Documents, provided, however, that such extension is made without prejudice to Lender's rights under the Loan Documents or applicable law to accelerate maturity of the Loan and Note (and Guarantor's obligations under the Guaranty), to receive interest at the Default Rate, or to exercise any other permissible and lawful rights or remedies against Borrower or Guarantor upon occurrence of an Event of Default, which rights are fully reserved by Lender.

2. Interest Rate. The Base Rate shall be Seventeen and One-Half Percent (17.5%) per annum, simple interest from and after September 30, 2019.

3. Payments of Interest. Principal and Fees. Section l(d) of the Note is hereby restated in its entirety to read as follows:           "(d) Borrower will prepay interest and make payments of principal and fees under this Note as follows:

1. Borrower will upon its execution of this letter agreement prepay to Lender interest due for the fourth quarter of 2019 in the amount of $11,059.03.

2. Borrower will on or before October 14, 2019 pay the sum of$12,500 representing loan due diligence fees, such fees to be payable $6,250 each to Lender and to Lender's Manager, Kodak Brothers Capital Management, LLC.

3. Borrower will on or before October 18, 2019 pay the sum of $27,500 representing $25,000 of loan monitoring fees and $2,500 of loan extension fees, such fees to be payable $13,750 each to Lender and to Lender's Manager, Kodak Brothers Capital Management, LLC.

4. Borrower will on or before October 31, 2019 pay the sum of$125,000 to Lender as a payment of principal. Borrower will incur a late fee of $5,000 every 7 days (or portion thereof) that the balance remains unpaid after October 31, 2019.

6. Borrower will on or before December 30, 2019 pay to Lender any unpaid and/or outstanding balances owed on the Note. If the Note and any late fees or other fees, interest, or principal is not paid in full by December 30, 2019, Borrower agrees that it will pay $25,000 to Lender as liquidated damages. Borrower agrees that it would be difficult, if not impossible to determine the amount of damages caused by Borrower's default and necessity for Lender to foreclose. Borrower stipulates that the liquidated damages is not a penalty, but rather a reasonable measure of damages, based on the Parties' experience and the nature of the losses that may result from the default.
