Promissory Note by and between Lantana Place, L.L.C, and Southside Bank dated April 28, 2017

FOR VALUE RECEIVED, the undersigned (herein called “Maker”) hereby promises to pay to the order of Southside Bank (“Lender”), in immediately available funds in lawful money of the United States of America, at the offices of Southside Bank in the City of Tyler, Smith County, Texas, the principal sum of TWENTY SIX MILLION THREE HUNDRED TEN THOUSAND FOUR HUNDRED EIGHTY TWO US DOLLARS ($26,310,482.00), or the aggregate principal advanced under this Note, if that amount is less, together with interest on the unpaid principal balance of this Note from day to day advanced and outstanding, as hereinafter provided.

The term “Advance(s)” as used in this Note means an advance of principal under this Note. All communications, instructions or directions to be delivered to Lender are to be directed to Lender’s office at 1201 South Beckham, Tyler, Texas, to the attention of Pam Cunningham or any other person subsequently designated in writing by Lender. Each of the following persons is authorized to request Advances and authorize payments hereunder: William H. “Beau”
Armstrong, III or Erin D. Pickens. Each request for an Advance shall be in form and substance satisfactory to Lender, and shall be accompanied by all documents and materials required under the Loan Agreement. Provided, however, Lender shall have no obligation to make any advances hereunder after December 31, 2018.

The term “Applicable Law” as used in this Note means the laws of the State of Texas (without regard to any conflict of laws principles) and applicable United States federal laws; provided, however, with respect to determination of the Maximum Rate and the Maximum Amount, this Note shall be governed by the laws of the State of Texas or the applicable federal laws of the United States, whichever laws allow the greater interest, as such laws now exist (or as such laws may be changed or amended or come into effect in the future, but only to the extent that any change, modification or new law permits a higher Maximum Rate or higher Maximum Amount).

The term “Business Day” as used in this Note means a day other than a Saturday, Sunday or other day on which banks in Tyler, Texas are authorized or required to be closed.

The term “Floating Rate Index” as used in this Note means a floating interest rate equal to the One Month London Interbank Offered Rate (Libor) as published in the “Borrowing Benchmarks - Money Rates” section of the Wall Street Journal from time to time (or a comparable rate selected by Lender if The Wall Street Journal ceases to publish such rate). The initial Floating Index Rate on the date of this Note is 0.995% per annum, provided, the Floating Index Rate shall be adjusted on the first day of each month (commencing on June 1, 2017) to the then current One Month London Interbank Offered Rate (Libor) as published in The Wall Street Journal on the last business day preceding such date.

The term “Loan Agreement” as used in this Note means a Construction Loan Agreement dated of even date herewith, by and between Maker and Lender, as same may be modified, amended or restated from time to time. This Note is subject to the terms of the Loan Agreement and evidences the “Loan” as therein defined.

The term “Maximum Rate” as used in this Note means the maximum non-usurious rate of interest per annum permitted by Applicable Law. The Maximum Rate shall be applied by taking into account all amounts characterized by Applicable Law as interest on the debt evidenced by this Note, so that the aggregate of all interest does not exceed the Maximum Amount.

The term “Past Due Rate” as used in this Note means a rate per annum equal to the Stated Rate plus four percent (4%) per annum computed on the Annual Basis.

    

The term “Stated Rate” as used in this Note means a floating annual interest rate equal to the greater of (i) the Floating Rate Index, plus 2.75%, or (ii) 3.00%.

Non-Revolving Advance Feature; Limitations on Advances. This Note shall be funded in multiple Advances, subject to the conditions and limitations on borrowings set forth in this Note or any other Loan Documents. Principal advanced and paid shall not be re-advanced. Notwithstanding anything herein to the contrary, Lender shall not be required to make any Advance if there is an Event of Default (as defined in the Loan Agreement) or if there exists any circumstance which, with the passing of time and/or the giving of notice, would constitute an Event of Default. Lender and Maker stipulate and agree that Chapter 346 of the Texas Finance Code shall not apply to this Note or any Advances, and that neither this Note nor any Advances shall be governed by or subject to the provisions of the said Chapter 346 in any manner whatsoever.

Interest Rate. The unpaid principal balance of this Note from day to day outstanding which is not past due shall bear interest at a rate per annum equal to the lesser of (a) the Maximum Rate or (b) the Stated Rate. Any principal of, and to the extent permitted by Applicable Law, any interest on, this Note which is not paid when due shall bear interest, from the date due and payable until paid, payable on demand, at a rate per annum equal to the lesser of (a) the Maximum Rate or (b) the Past Due Rate. Subject always to limitation by the Maximum Rate, interest on this Note at the Stated Rate and the Past Due Rate shall be calculated on the basis (the “Annual Basis”) of the Actual/360 method, pursuant to which interest shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed.

Terms of Payment. Interest shall be due and payable monthly as it accrues on the first day of each month beginning June 1, 2017 and continuing regularly thereafter until and including November 1, 2020. The principal balance of this Note outstanding and unpaid on November 1, 2020 shall be due and payable in equal monthly installments of principal and interest based on a 30 year amortization, payable on the first day of each month, beginning on December 1, 2020 and continuing regularly thereafter; provided, however, Lender may, at Lender’s option, upon each change in the Stated Rate, change the amount of the monthly installments of principal and interest in order to maintain at all times a 30 year amortization notwithstanding any changes in the Stated Rate. Lender shall give Maker at least ten days notice of any such changes. Provided, further, all principal and all accrued interest remaining unpaid on April 28, 2023 (the final maturity date), shall then be due and payable in full. Whenever any payment shall be due under this Note on a day that is not a Business Day, the date on which such payment is due shall be extended to the next succeeding Business Day, and such extension of time shall be included in the computation of the amount of interest then payable. All payments made on this Note shall be applied, to the extent thereof, first to accrued but unpaid interest and the balance to unpaid principal. Any monthly installment that is not paid within ten days after the due date shall be

subject to a one-time late fee in an amount equal to 5% of the past due amount, which fee shall be due and payable only upon demand by Lender.

Prepayments. Principal may be prepaid in whole or in part without any penalty, premium or fee, provided that Lender shall not be required to accept any prepayment unless Maker gives Lender at least thirty (30) days prior written notice of Maker’s intention to make such prepayment, which notice shall state the amount of the prepayment and the date on which Maker intends to make the prepayment. Prepayments of principal shall be applied to the last installments of principal payable hereunder.

Security/Loan Documents. The security for this Note includes, without limitation, a Deed of Trust and Security Agreement of even date herewith from Maker, as Grantor, for the benefit of Lender. This Note, the said Deed of Trust, the Loan Agreement and any other documents now or hereafter securing, guaranteeing or executed in connection with the loan evidenced by this Note, are, as the same have been or may be amended, restated, modified or supplemented from time to time, herein sometimes called individually a “Loan Document” and collectively referred to as the “Loan Documents.” To the extent that this Note conflicts with or is in any way incompatible with any other Loan Document, Lender shall determine, at Lender’s discretion, which document governs and controls.

Event of Default. Upon the occurrence, and during the continuance, of an Event of Default, the holder hereof shall have the rights to deny further Advances, declare the unpaid principal balance and accrued but unpaid interest on this Note at once due and payable (and upon such declaration, the same shall be at once due and payable), to foreclose any liens and security interests securing payment hereof and/or to exercise any of its other rights, powers and remedies under this Note, under any other Loan Document, or at law or in equity.

Remedies. All rights and remedies provided for in this Note and in any other Loan Document are cumulative of each other and of any and all other rights and remedies existing at law or in equity. The resort to any right or remedy provided for hereunder or under any such other Loan Document or provided for by law or in equity shall not prevent the concurrent or subsequent employment of any other appropriate rights or remedies. No single or partial exercise by the holder hereof of any right, power or remedy shall exhaust the same or shall preclude any other or further exercise thereof, and every such right, power or remedy may be exercised at any time and from time to time. Neither the failure by the holder hereof to exercise, nor delay by the holder hereof in exercising, the right to accelerate the maturity of this Note or any other right, power or remedy upon any Event of Default shall be construed as a waiver of such Event of Default or as a waiver of the right to exercise any such right, power or remedy at any time. Without limiting the generality of the foregoing provisions, the acceptance by the holder hereof from time to time of any payment under this Note which is past due or which is less than the payment in full of all amounts due and payable at the time of such payment, shall not (i) constitute a waiver of or impair or extinguish the rights of the holder hereof to accelerate the maturity of this Note or to exercise any other right, power or remedy at the time or at any subsequent time, or nullify any prior exercise of any such right, power or remedy, or (ii) constitute a waiver of the requirement of punctual payment and performance, or a novation in any respect.

Attorney’s Fees. If any holder of this Note retains an attorney in connection with any Event of Default or at maturity or to collect, enforce or defend this Note or any other Loan Document in any lawsuit or in any probate, reorganization, bankruptcy or other proceeding, or if

Maker sues any holder in connection with this Note or any other Loan Document and does not prevail, then Maker agrees to pay to each such holder, in addition to principal and interest, all reasonable costs and expenses incurred by such holder in trying to collect this Note or in any such suit or proceeding, including reasonable attorneys' fees.

Usury Savings. It is the intent of Lender and Maker and all other parties to the Loan Documents to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between Lender or any other holder hereof and Maker (or any other party liable with respect to any indebtedness under the Loan Documents) are hereby limited by the provisions of this paragraph which shall override and control all such agreements, whether now existing or hereafter arising. In no way, nor in any event or contingency (including but not limited to prepayment, Event of Default, demand for payment, or acceleration of maturity), shall the interest taken, reserved, contracted for, charged or received under this Note or otherwise, exceed the maximum non-usurious amount permitted by Applicable Law (the “Maximum Amount”). If, from any possible construction of any document, interest would otherwise be payable in excess of the Maximum Amount, any such construction shall be subject to the provisions of this paragraph and such document shall be automatically reformed and the interest payable shall be automatically reduced to the Maximum Amount, without the necessity of execution of any amendment or new document. If the holder hereof shall ever receive anything of value which is characterized as interest under Applicable Law and which would apart from this provision be in excess of the Maximum Amount, an amount equal to the amount which would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the indebtedness evidenced hereby in the inverse order of its maturity and not to the payment of interest, or refunded to Maker or the other payor thereof if and to the extent such amount which would have been excessive exceeds such unpaid principal. The right to accelerate maturity of this Note or any other indebtedness does not include the right to accelerate any interest which has not otherwise accrued on the date of such acceleration, and the holder hereof does not intend to charge or receive any unearned interest in the event of acceleration. All interest paid or agreed to be paid to the holder hereof shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread throughout the full stated term (including any renewal or extension) of such indebtedness so that the amount of interest on account of such indebtedness does not exceed the Maximum Amount.

Waivers. If there is more than one Maker of this Note, all Makers shall be jointly and severally liable for payment of the indebtedness evidenced hereby and all other obligations under the Loan Documents. Except as otherwise expressly provided in the Loan Documents, Maker and all sureties, endorsers, guarantors and any other party now or hereafter liable for the payment of this Note in whole or in part, hereby severally (i) waive demand, presentment for payment, notice of dishonor and of nonpayment, protest, notice of protest, notice of intent to accelerate, notice of acceleration and all other notice (except any notices which are specifically required by this Note or any other Loan Document), filing of suit and diligence in collecting this Note or enforcing any of the security herefor; (ii) agree to any substitution, subordination, exchange or release of any such security or the release of any party primarily or secondarily liable hereon; (iii) agree that the holder hereof shall not be required first to institute suit or exhaust its remedies hereon against Maker or other party liable or to become liable hereon or to enforce its rights against them or any security herefor; (iv) consent to any extension or postponement of time of payment of this Note for any period or periods of time and to any partial payments, before or after maturity, and to any other indulgences with respect hereto, without notice thereof to any of them; (v) submit (and waive all rights to object) to personal jurisdiction in the State of Texas, and venue in Smith County, for the enforcement of any and all obligations under the Loan

Documents; and (vi) waive all rights and defenses under Sections 51.003, 51.004 and 51.005 of the Texas Property Code, as amended.

The loan evidenced by this Note is solely for business, commercial, investment or other similar purpose and is not for personal, family, household or agricultural purposes. The holder of this Note may sell, or offer to sell, the loan evidenced by this Note to a bank or other financial institution chartered under the laws of the United States or any State, and the holder of this Note is hereby authorized to disseminate to any such purchaser or prospective purchaser any information that holder has pertaining to the loan evidenced by this Note, including, without limitation, credit information on the Maker and any guarantors of this Note.

Jurisdiction and Venue; Waiver of Jury. THIS NOTE IS PAYABLE IN SMITH COUNTY, TEXAS, AND EXCLUSIVE VENUE FOR ANY LITIGATION WITH RESPECT TO THIS NOTE SHALL BE IN THE FEDERAL OR STATE COURTS SITTING IN TYLER, SMITH COUNTY, TEXAS AND HAVING JURISDICTION. MAKER AND LENDER HEREBY WAIVE THEIR RIGHT TO A JURY TRIAL WITH RESPECT TO ANY CLAIMS OR DISPUTES RELATING TO THIS NOTE OR ANY OF THE OTHER LOAN DOCUMENTS.
