PROMISSORY
NOTE


 


		$1,196,686	November
30, 2018



 


FOR
VALUE RECEIVED, pursuant to the terms of this Promissory Note (this “Note”), SOUTHLAND HOLDINGS LLC, a Texas
limited liability company (“Borrower”), promises to pay to the order of RUDOLPH V. RENDA (“Lender”),
at 608 Henrietta Creek Road, Roanoke, Texas 76262, or at such other place as may be designated by Lender, without setoff, the principal
amount of $1,196,686 in lawful money of the United States, with interest thereon from the date hereof until paid at the rate below set
forth.


 


All
unpaid interest that has accrued on the outstanding principal amount of this Note shall be due and payable annually beginning on the
31st day of December, 2018, and continuing on each subsequent December 31 occurring thereafter. Any and all remaining unpaid principal
of and interest on this Note shall be due and payable in full on November 30, 2023 (the “Maturity Date”). This
Note is unsecured.


 


The
outstanding principal balance hereof shall bear interest at a rate per annum equal to the long-term applicable federal rate with a monthly
compounding period, as published by the Internal Revenue Service from time to time for purposes of Section 1274(d) of the Internal Revenue
Code or, if greater, the minimum rate of interest necessary under applicable law to avoid the existence of a taxable benefit to Borrower
in respect of the amount of interest payable under this Note, as reasonably determined by Lender. Interest shall be computed on the basis
of 365 or 366 days, as the case may be, and the actual number of days elapsed (including the first day but excluding the last day). In
no event shall this Note bear interest at a rate in excess of the highest rate permitted by applicable law.


 


This
Note may be prepaid in whole or in part at any time and from time to time without premium or penalty. Lender in its sole discretion shall
determine how and in what proportions to apply amounts repaid against principal and/or accrued interest hereunder. Lender is hereby authorized
to record on a schedule or to otherwise record in accordance with his usual practice the date and amount of each principal payment and
interest payment hereunder.


 


If
Borrower fails to make any payment hereunder when due, the unpaid balance of this Note shall, at the option of Lender and without notice
or demand, mature and become immediately payable. In addition, the unpaid balance of this Note shall automatically mature and become
immediately payable in the event Borrower becomes the subject of bankruptcy or other insolvency proceedings. Lender’s receipt of
any payment after the occurrence of a default shall not constitute a waiver of such default or of any of Lender’s rights and remedies.
No delay on the part of Lender in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise
by Lender of any right or remedy shall preclude any other or further exercise thereof or the exercise of any other right or remedy.


 


Borrower
waives presentment, notice of dishonor and protest and agrees to pay, on demand, ail of Lender’s costs of collection, before and
after judgment, including reasonable attorneys’ fees and legal expenses.


 


This
Note is governed by the internal laws of the State of Texas, excluding conflict of law principles providing for the application of the
laws of another jurisdiction.
