 EXHIBIT 10.19A 
  
 AMENDMENT TO EXHIBIT “A” 
 OF THE EMPLOYMENT AGREEMENT 
 BETWEEN ACR GROUP, INC. AND 
 A. STEPHEN TREVINO 
  
 WHEREAS, ACR Group, Inc. (“Company”) has previously entered into an Employment Agreement (the “Agreement”) with A. Stephen
Trevino (“Employee”) effective March 1, 2004; 
  
 WHEREAS, pursuant to Section 13(b) of the Agreement, the parties have reserved the right to amend the Agreement with the written consent of each party thereto: 
  
 WHEREAS, the Board of Directors of the Company and the Employee have determined that Section 6 of Exhibit
“A” of the Agreement did not reflect the intent of the parties with respect to the long-term incentive component of the Agreement and as a result, such provision in the Agreement is void and of no effect; 
  
 WHEREAS, the parties hereto have determined to amend Section 6 of
Exhibit “A” of the Agreement in order to reflect their mutual intent with respect to the long-term incentive component of the Agreement, effective as of March 1, 2004, as follows: 
  
 NOW THEREFORE, the Agreement is amended as follows: 
  
 1. Section 6 of Exhibit “A” of the Agreement shall be void ab
initio and deleted in its entirety and the following substituted in its place, effective as of March 1, 2004: 
  
 “6. Restricted Shares. 500,000 shares of restricted stock of the Company (Company common stock par value $0.01) are awarded to the Employee
(“Restricted Shares”). Restricted Shares listed hereunder are not transferable by the Employee until the date that the applicable shares become vested. Notwithstanding such restrictions, the Employee shall retain all voting rights with
respect to such non-vested Restricted Shares. However, the Employee shall not be entitled to any dividends paid with respect to such shares, and shall have no other rights respecting such shares except as specifically set forth in this Agreement.
The Company will file appropriate registration documents (and bear all such costs) pertaining to the vested Restricted Shares as reasonably requested by the Employee. As of the date any such shares become vested, then those shares shall
contemporaneously become transferable and payable to the Employee within thirty (30) days thereof. 
  
 Vesting Schedule. The Restricted Shares shall vest as follows: 
 83,333 Restricted Shares to
vest as of March 1, 2005. 
 83,333 Restricted Shares to vest as of March 1, 2006. 
 83,333 Restricted Shares to vest as of March 1, 2007. 
 83,333 Restricted Shares to vest as of March 1, 2008. 
 83,333 Restricted Shares to vest as of March 1, 2009. 
 83,335 Restricted Shares to vest as of March 1, 2010. 
  
 Notwithstanding any other provisions of this Agreement, in the event of a Change of Control (as defined in 

 
this Agreement), then all Restricted Shares hereunder, to the extent not already vested, shall become vested, fully transferable, and without restriction.

 In the event this Agreement is terminated for any reason, other than under Section 4(a)(vi) and/or Section 4(a)(vii), prior to the vesting of Restricted
Shares, such non-vested Restricted Shares shall be forfeited by the Employee back to the Company. 
 To the extent the distribution to the Employee of shares
of Company common stock which have become vested hereunder are subject to income and employment taxes which the Company determines must be withheld with respect to the distribution of such shares of common stock, no such shares shall be distributed
to the Employee until satisfactory arrangements (as determined by the Company) will have been made by the Employee with respect to the payment of any applicable income and employment taxes which the Company determines it must withhold with respect
to such shares of common stock. 
 The number of Restricted Shares granted hereunder shall be automatically adjusted in the event of any Recapitalization
Event (as defined below) so as to prevent the enlargement or dilution of the Employees’ non-vested Restricted Shares as of such Recapitalization Event date. Recapitalization Event includes spin-offs of assets, stock splits, combinations of
shares, recapitalizations, mergers, consolidations, reorganizations, liquidations, issuance of rights or warrants and similar transactions or events involving the Company.” 
  
 2. Ratification. Except as expressly amended by this Amendment, the Agreement is unchanged, is hereby ratified and confirmed
and remains in full force and effect. 
  

 IN WITNESS WHEREOF, the Employee has hereunto set his hand and the Company has caused this
Amendment to be executed in its name and on its behalf, effective as of March 1, 2004.

collateral information as Bank may from time to time require, including, without limitation, the Borrowing Base Certificates for the relevant month. Borrower acknowledges that the Borrowing Base was established by Bank with the understanding, among
other things, that the aggregate of all returns, rebates, discounts, credits and allowances for the immediately preceding three (3) months at all times shall be less than five percent (5%) of gross sales of Eligible Finished Goods Inventory for said
period. If such dilution of accounts receivable for the immediately preceding three (3) months at any time exceeds five percent (5%) of gross sales of Eligible Finished Goods Inventory for said period, or if there at any time exists any other
matters, events, conditions or contingencies which Bank reasonably believes may affect payment of any portion of such accounts receivable, Bank, in its sole discretion, may reduce the foregoing advance rate against Eligible Accounts Receivable to a
percentage appropriate to reflect such additional dilution and/or establish additional reserves against Borrower’s Eligible Accounts Receivable as Bank, in its sole discretion, but consistent with its commercial practices for similar loans
shall determine. 
  
 As used herein, “Eligible Accounts
Receivables” shall consist solely of trade accounts created in the ordinary course of business, upon which Borrower’s or its Subsidiaries’ respective right to receive payment is absolute and not contingent upon the fulfillment of any
condition whatsoever, and in which Bank has a perfected and undisputed security interest of first priority, but in any event, and shall specifically not include any of the following: 
  

	 	(i)	any account which remains unpaid more than ninety (90) days after its invoice date; 

  

	 	(ii)	that portion of any account for which there exists any right of setoff, defense or discount (except regular discounts allowed in the ordinary course of business to promote prompt
payment) or for which any defense or counterclaim has been asserted; 

  

	 	(iii)	any account which represents an obligation of any state or municipal government or of the government of the United States of America or any political subdivision thereof (except
accounts which represent obligations of the government of the United States of America and for which the assignment provisions of the Federal Assignment of Claims Act, as amended or recodified from time to time, have been complied with to
Bank’s satisfaction, as determined in its sole discretion); 

	 	(iv)	any account which represents an obligation of an account debtor located in a foreign country or which is payable in a currency other than the legal and lawful currency of the United
States of America; 

  

	 	(v)	any account which arises from the sale or lease to, or performance of services for, or represents an obligation of, an employee, affiliate, partner, member, parent or Subsidiary of
Borrower or of any Subsidiary; 

  

	 	(vi)	that portion of any account, which represents interim or progress billings to the Borrower;

are not eligible pursuant to clause (i) above; 

  

	 	(viii)	that portion of any account from an account debtor which represents the amount by which the total sum of all accounts owing by said account debtor exceeds twenty-five percent (25%)
of total Eligible Accounts Receivable; 

  

	 	(ix)	any account deemed ineligible by Bank when Bank, in its sole discretion, deems the creditworthiness or financial condition of the account debtor, or the industry in which the
account debtor is engaged, to be unsatisfactory; 

  

	 	(x)	any account arising from bill and hold (deferred) or consignment sales or transactions; 

  

	 	(xi)	any account owing by any account debtor to which Borrower or any of its Subsidiaries owes offsetting accounts payable obligations; 

  

	 	(xii)	any “COD” account or any other account which is payable, or which otherwise will be paid, in cash or its equivalent, immediately upon delivery of the related instrument;

  

	 	(xiii)	any account arising from interest or other finance charge of any type; or 

  

	 	(xiv)	Reconciliation Variance. 

  
 As used herein, “Eligible Finished Goods Inventory” shall consist solely of Borrower’s and the Subsidiaries inventory of finished goods
created or otherwise arising in the ordinary course of business and which is owned by Borrower or the Subsidiaries and which is marketable to customers in the ordinary course of business and in which Bank has a perfected and undisputed security
interest of first priority, but, in any event, shall specifically not include any of the following: 
  

	 	(i)	any item of finished goods inventory acquired or otherwise obtained on a consignment basis; 

	 	(ii)	any item of finished goods inventory belonging to any customer of Borrower or any Subsidiary (or any other person), including, without limitation, pursuant to any bill and hold sale
or otherwise; 

  

	 	(iii)	any item of finished good inventory which is not present in the United States of America; 

  

	 	(iv)	any item of finished goods inventory classified in the Borrower’s or its Subsidiaries’ books as a returned product, whether or not under or pursuant to a warranty;

  

	 	(v)	any item of finished goods inventory which has not sold within a period of 360 days beginning from the date on which such item first became finished goods; 

 

	 	(vi)	any item of finished goods inventory if any part (including, without limitation, component parts) thereof is subject to a lien, security interest or other encumbrance of any kind in
favor of any person or entity (other than the Bank as contemplated hereby). 

  
 The Value of Eligible Finished Goods Inventory shall be determined according to the average cost method. 
  
 All of the foregoing shall be determined by Bank upon receipt and review of all collateral reports required hereunder and such other documents and
collateral information as Bank may from time to time require, including, without limitation, the Borrowing Base Certificate for the relevant month. 
  
 Notwithstanding anything contained herein or elsewhere to the contrary, in the event pursuant to an interest rate protection agreement entered into by and
between the Bank and the Borrower, the Bank underwrites any interest rate protection exposure, and the amount of such exposure increases at any time by more than 25% (as compared by the amount of such exposure at the time such agreement was entered
into), all as determined by Bank in its sole discretion, then the Borrowing Base shall be reduced by the amount of such exposure in excess of such 25% increase. 
  

(c) Letter of Credit Subfeature. As a subfeature under the Line of Credit, Bank agrees from time to time during the term thereof to issue or
cause an affiliate to issue letters of credit for the account of Borrower which letters of credit shall be used only for general corporate purposes of Borrower and the Subsidiaries, including routine capital expenditures made in the ordinary course
of business, and for no other purpose (each, a “Letter of Credit” and collectively, “Letters of Credit”); provided, however, that the aggregate undrawn amount of all outstanding Letters of Credit and all amounts
drawn and unreimbursed under any and all Letters of Credit shall not at any time exceed TWO MILLION AND NO/100 DOLLARS ($2,000,000.00). The form and substance of each Letter of Credit shall be subject to approval by Bank, in its sole discretion.
Each Letter of Credit shall be issued for a term not to exceed three hundred and sixty-five (365) 

 days, as designated by Borrower; provided, however, that no Letter of Credit shall have an expiration date
subsequent to the maturity date of the Line of Credit. The undrawn amount of all Letters of Credit and all amounts drawn and unreimbursed under any Letter of Credit shall be reserved under the Line of Credit and shall not be available for borrowings
thereunder. Each Letter of Credit shall be subject to the additional terms and conditions of the Letter of Credit agreements, applications and any related documents required by Bank in connection with the issuance thereof. Each drawing paid under a
Letter of Credit shall be deemed an advance under the Line of Credit and shall be repaid by Borrower in accordance with the terms and conditions of this Agreement applicable to such advances and the Line of Credit Note; provided, however,
that if advances under the Line of Credit are not available, for any reason, at the time any drawing is paid, then Borrower shall immediately pay to Bank the full amount drawn, together with interest thereon from the date such drawing is paid to the
date such amount is fully repaid by Borrower at the rate of interest applicable to advances under the Line of Credit. In such event Borrower agrees that Bank, in its sole discretion, may debit any account maintained by Borrower or any of its
Subsidiaries with Bank for the amount of any such drawing. 
  
 (d)
Borrowing and Repayment. Borrower may from time to time during the term of the Line of Credit borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, reservations, terms and conditions
contained herein or in the Line of Credit Note; provided, however, that the total outstanding borrowings under the Line of Credit shall not at any time exceed the lesser of (i) maximum principal amount available thereunder, as set

 ARTICLE VII

 SECTION 7.6 NO THIRD PARTY BENEFICIARIES. This Agreement is made and entered into for the sole protection and benefit of the parties hereto and
their respective permitted successors and assigns, and no other person or entity shall be a third party beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement or any other of the Loan Documents to
which it is not a party. 
  
 SECTION 7.7 TIME. Time is of
the essence of each and every provision of this Agreement and each and every provision of the other Loan Documents. 
  
 SECTION 7.8 SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be prohibited by, or invalid under, applicable law, such provision
shall be ineffective only to the extent of such prohibition or invalidity without invalidating the remainder of such provision or any remaining provisions of this Agreement. 
  
 SECTION 7.9 COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which when executed
and delivered shall be deemed to be an original, and all of which when taken together shall constitute one and the same Agreement. 
  
 SECTION 7.10 GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas. 
  
 SECTION 7.11 SAVINGS CLAUSE. It is the intention of the parties hereto
to comply strictly with applicable usury laws. Accordingly, notwithstanding any provision to the contrary herein or in any other of the Loan Documents, in no event shall any Loan Document require the payment or permit the payment, taking, reserving,
receiving, collection or charging of any sums constituting interest under applicable laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified from time to time (the “Maximum Rate”). If any such
excess interest is called for, contracted for, charged, taken, reserved or received in connection with any Loan Document, or in any communication by Bank or any other person to Borrower or any other person, or in the event that all or part of the
principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved or received on the amount of
principal actually outstanding from time to time under the Loan Documents shall exceed the Maximum Rate, then in such event it is agreed that: (a) the provisions of this paragraph shall govern and control; (b) neither Borrower nor any other Person
now or hereafter liable for the payment of any interest shall be obligated to pay the amount of such interest to the extent it is in excess of the Maximum Rate; (c) any such excess interest which is or has been received by Bank, notwithstanding this
paragraph, shall be credited against 

 the then unpaid principal balance hereof or thereof, or if any of the Loan Documents has been or would be paid in full by
such credit, refunded to Borrower; and (d) the provisions of each of the Loan Documents, and any other communication to Borrower, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other
document, to the Maximum Rate. The right to accelerate the maturity of the Loan Documents does not include the right to accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date of
acceleration. Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or received in connection with any of the Loan Documents which are made for the purpose of determining whether such rate
exceeds the Maximum Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of such Loan Documents, including all prior and subsequent renewals and
extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received by Bank. The terms of this paragraph shall be deemed to be incorporated into each of the other Loan Documents. 
  
 To the extent, if any, that either Chapter 303 or 306, or both, of the Texas
Finance Code apply in determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling by using the weekly ceiling from time to time in effect, subject to Bank’s right subsequently to change such method in accordance
with applicable law, as the same may be amended or modified from time to time. 
  
 SECTION 7.12 RIGHT OF SETOFF; DEPOSIT ACCOUNTS. Upon and after the occurrence of an Event of Default, (a) Borrower hereby authorizes Bank, at any time and from time to time, without notice, which is hereby
expressly waived by Borrower, and whether or not Bank shall have declared any credit subject hereto to be due and payable in accordance with the terms hereof, to set off against, and to appropriate and apply to the payment of, Borrower’s
obligations and liabilities under the Loan Documents (whether matured or unmatured, fixed or contingent, liquidated or unliquidated), any and all amounts owing by Bank to Borrower (whether payable in U.S. dollars or any other currency, whether
matured or unmatured, and in the case of deposits, whether general or special (except trust and escrow accounts), time or demand and however evidenced), and (b) pending any such action, to the extent necessary, to hold such amounts as collateral to
secure such obligations and liabilities and to return as unpaid for insufficient funds any and all checks and other items drawn against any deposits so held as Bank, in its sole discretion, may elect. Borrower hereby grants to Bank a security
interest in all deposits and accounts maintained with Bank and with any other financial institution to secure the payment of all obligations and liabilities of Borrower to Bank under the Loan Documents. 
  
 SECTION 7.13 BUSINESS PURPOSE. Borrower represents and warrants that
each credit subject hereto is for a business, commercial, investment, agricultural or other similar purpose and not primarily for a personal, family or household use. 
  
 SECTION 7.14 FURTHER ASSURANCES. Borrower agrees that, from time to time upon the request of Bank, Borrower will
execute and deliver, and will cause each of its Subsidiaries to execute and deliver, all such further agreements, documents and other instruments, and do all such other acts and things as Bank may reasonably request to fully effect the purposes of
this Agreement and the other Loan Documents and protect, preserve and enforce its security interests and liens in the Collateral. 

 SECTION 7.15 ARBITRATION. 
  
 (a) Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims,
disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise arising out of or relating to in any way (i) the loan and related Loan
Documents which are the subject of this Agreement and its negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for
additional credit. 
  
 (b) Governing Rules. Any arbitration
proceeding will (i) proceed in a location in Texas selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law
provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the
claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes
(the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the
terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any
dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law. 
  
 (c) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The
arbitration requirement does not limit the right of Bank to (i) foreclose against any Collateral, (ii) exercise self-help remedies relating to Collateral (including, without limitation, proceeds), such as setoff or repossession; or (iii) obtain
provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or
obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph. 
  
 (d) Arbitrator Qualifications and Powers. Any arbitration proceeding
in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy
exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided, however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral
attorney licensed in the State of Texas with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an 

 issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration
proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The
arbitrator shall resolve all disputes in accordance with the substantive law of Texas and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make
effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules
of Civil Procedure, the Texas Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or
pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief. 

 
 (e) Discovery. In any arbitration proceeding discovery will be
permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date and within 180 days of the filing of
the dispute with the AAA. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s
presentation and that no alternative means for obtaining information is available. 
  
 (f) Class Proceedings and Consolidations. The resolution of any dispute arising pursuant to the terms of this Agreement shall be determined by a separate arbitration proceeding and such dispute shall not be
consolidated with other disputes or included in any class proceeding. 
  
 (g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding. 
  
 (h) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party
required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan
Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

the undersigned ACR GROUP, INC., a Texas corporation (“Borrower”), promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking association (“Bank”), at its office at 1160 Dairy Ashford, Suite 160,
Houston, Texas 77079, or at such other place as the holder hereof may designate, in lawful money of the United States of America and in immediately available funds, the principal sum of THIRTY MILLION AND NO/100 DOLLARS ($30,000,000.00), or so much
thereof as may be advanced and outstanding, with interest thereon (or so much thereof as may be advanced and outstanding), to be computed on each advance from the date of its disbursement as set forth herein. 
  
 DEFINITIONS: 
  
 As used herein, the following terms shall have the meanings set forth after each, and any other term defined in this Note
shall have the meaning set forth (i) at the place defined or (ii) if not defined, in the “Credit Agreement” (hereinafter defined): 
  
 (a) “Applicable Margin” means, as applicable, the Applicable Prime Rate Margin or the Applicable LIBOR Margin as set forth in Exhibit A attached
hereto and incorporated herein by this reference as if fully set forth herein. 
  
 (b) “Business Day” means any day except a Saturday, Sunday or any other day on which commercial banks in Texas are authorized or required by law to close. 
  
 (c) “Credit Agreement” means that certain Credit Agreement dated of
even date herewith by and between Borrower and Bank as the same may be amended, amended and restated, supplemented or modified from time to time. 
  
 (d) “LIBOR” means the rate per annum (rounded upward, if necessary, to the nearest whole 1/8 of 1%) and determined pursuant to the following
formula: 
  

					
	 LIBOR
	  	=	 	 Base LIBOR

	 	  	 	 	100% - LIBOR Reserve Percentage

  
 (i) “Base
LIBOR” means the rate per annum for United States dollar deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the understanding that such rate is quoted by Bank for the purpose of calculating effective rates of interest for loans
making reference thereto, on the first day of a Fixed Rate Term for delivery of funds on said date for a period of time approximately equal to the number of days in such Fixed Rate Term and in an amount approximately equal to the principal amount to
which such Fixed Rate Term applies. Borrower understands and agrees that Bank may base its quotation of the Inter-Bank Market Offered Rate upon such offers or other market indicators of the Inter-Bank Market as Bank in its discretion deems
appropriate including, but not limited to, the rate offered for U.S. Dollar deposits on the London Inter-Bank Market. 

 (ii) “LIBOR Reserve Percentage” means the reserve percentage prescribed by the Board of
Governors of the Federal Reserve System (or any successor) for “Eurocurrency Liabilities” (as defined in Regulation D of the Federal Reserve Board, as amended), adjusted by Bank for expected changes in such reserve percentage during the
applicable Fixed Rate Term. 
  
 (e) “Prime Rate” means
at any time the rate of interest most recently announced within Bank at its principal office as its Prime Rate, with the understanding that the Prime Rate is one of Bank’s base rates and serves as the basis upon which effective rates of
interest are calculated for those loans making reference thereto, and is evidenced by the recording thereof after its announcement in such internal publication or publications as Bank may designate. 
  
 INTEREST: 
  
 (a) Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 365/366
day year, as applicable, actual days elapsed, at the lesser of (i) either (A) a fluctuating rate per annum at Prime Interest Rate minus the Applicable Margin or (B) a one, two or three month LIBOR plus the Applicable Margin. When
interest is determined in relation to the Prime Rate, each change in the rate of interest hereunder shall become effective on the date each Prime Rate change is announced within Bank. With respect to each LIBOR selection hereunder, Bank is hereby
authorized to note the date, principal amount, interest rate and Fixed Rate Term applicable thereto and any payments made thereon on Bank’s books and records (either manually or by electronic entry) and/or on any schedule attached to this Note,
which notations shall be prima facie evidence of the accuracy of the information noted. 
  
 (b) Selection of Interest Rate Options. At any time any portion of this Note bears interest determined in relation to LIBOR, it may be continued by Borrower at the end of the Fixed Rate Term applicable thereto
so that all or a portion thereof bears interest determined in relation to the Prime Rate or to LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Prime Rate,
Borrower may convert all or a portion thereof so that it bears interest determined in relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as Borrower requests an advance hereunder or wishes to select a LIBOR option for all
or a portion of the outstanding principal balance hereof, and at the end of each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the interest rate option selected by Borrower; (ii) the principal amount subject thereto; and (iii) for
each LIBOR selection, the length of the applicable Fixed Rate Term. Any such notice may be given by telephone (or such other electronic method as Bank may permit) so long as, with respect to each LIBOR selection, (A) if requested by Bank, Borrower
provides to Bank written confirmation thereof not later than three (3) Business Days after such notice is given, and (B) such notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate Term, or at a later time during any Business
Day if Bank, at it’s sole option but without obligation to do so, accepts Borrower’s notice and quotes a fixed rate to Borrower. If Borrower does not immediately accept a fixed rate when quoted by Bank, the quoted rate shall expire and any
subsequent LIBOR request from Borrower shall be subject to a redetermination by Bank of the applicable fixed rate. If no specific designation of interest is made at the time any advance is requested hereunder or at the end of any Fixed Rate Term,
Borrower shall be deemed to have made a Prime Rate interest selection for such advance or the principal amount to which such Fixed Rate Term applied. 
  

 -2- 

 (c) Taxes and Regulatory Costs. Borrower shall pay to Bank immediately upon demand, in addition to
any other amounts due or to become due hereunder, any and all (i) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in any
manner to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign
governmental authority or resulting from compliance by Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR to the extent they are not
included in the calculation of LIBOR. In determining which of the foregoing are attributable to any LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon
Borrower. 
  
 (d) Payment of Interest. Interest accrued on
this Note shall be payable on the last day of each month, commencing the last day of the month following the initial advance made hereunder, and shall continue monthly and regularly thereafter on the last day of each month thereafter and on the
maturity hereof. 
  
 (e) Default Interest. From and after
the maturity date of this Note, or such earlier date as all principal owing hereunder becomes due and payable by acceleration or otherwise, the outstanding principal balance of this Note shall bear interest until paid in full at an increased rate
per annum (computed on the basis of a 365/366-day year, as the case may be, actual days elapsed) equal to four percent (4%) above the rate of interest from time to time applicable to this Note, but in no event at a rate greater than the Maximum
Rate. 
  
 BORROWING AND REPAYMENT: 
  
 (a) Borrowing and Repayment. Borrower may from time to time during
the term of this Note borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of any document executed in connection with or governing this Note (including
the Credit Agreement); provided however, that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. The unpaid principal balance of this obligation at any time shall be the total
amounts advanced hereunder by the holder hereof less the amount of principal payments made hereon by or for any Borrower, which balance may be endorsed hereon from time to time by the holder. The outstanding principal balance of this Note shall be
due and payable in full on August 31, 2006. Notwithstanding anything contained herein or in any other of the Loan Documents or elsewhere to the contrary, upon the payment in full or termination of the Term Loan (howsoever occurring), all amounts due
hereunder, whether principal, accrued, unpaid interest, fees, expenses or otherwise, shall be ipso facto without any notice of any kind be due and payable in full. 
  
 (b) Advances. Advances hereunder, to the total amount of the principal sum stated above, may be made by the holder at
the oral or written request of Alex Trevino, Jr., Steve Trevino or Tony Maresca, any one acting alone, or any person who shall have been authorized by any of them to request advances and direct the disposition of any advances until written notice of
the revocation of such authority is received by the holder at the office designated above, 
  

 -3- 

 which advances, when so deposited, shall be conclusively presumed to have been made to or for the benefit of each
Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall have no obligation to determine whether any person requesting an advance is or has been
authorized by Borrower. 
  
 (c) Application of Payments.
Each payment made on this Note shall be credited first, to charges, costs and expenses, including attorneys fees and all other amounts owing pursuant to the Credit Agreement or any other Loan Document, second to any accrued interest then remaining
unpaid and third, to the outstanding principal balance hereof. All payments credited to principal shall be applied first, to the outstanding principal balance of this Note which bears interest determined in relation to the Prime Rate, if any, and
second, to the outstanding principal balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest Fixed Rate Term first. 
  
 PREPAYMENT: 
  
 (a) Prime Rate. Subject to the last sentence of Paragraph (a) under Borrowing and Repayment above, Borrower may prepay principal on any portion of
this Note which bears interest determined in relation to the Prime Rate at any time, in any amount and without penalty. 
  
 (b) LIBOR. Borrower may prepay principal on any portion of this Note which bears interest determined in relation to LIBOR at any time and in the
minimum amount of One Hundred Thousand and 00/100 Dollars ($100,000.00); provided, however, that if the outstanding principal balance of such portion of this Note is less than said amount, the minimum prepayment amount shall be the entire
outstanding principal balance thereof. In consideration of Bank providing this prepayment option to Borrower, or if any such portion of this Note shall become due and payable at any time prior to the last day of the Fixed Rate Term applicable
thereto, Borrower shall pay to Bank immediately upon demand a fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such Fixed Rate Term matures, calculated as follows for
each such month: 
  

	 	(i)	Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until
the last day of the Fixed Rate Term applicable thereto. 

  

	 	(ii)	Subtract from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such Fixed
Rate Term at LIBOR in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid. 

  

	 	(iii)	If the result obtained in (ii) for any month is greater than zero, discount that difference by LIBOR used in (ii) above. 

  
 Borrower acknowledges that prepayment of such amount may result in Bank incurring additional
costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a
reasonable estimate of the prepayment costs, expenses and/or liabilities of Bank. 
  

 -4- 

 EVENTS OF DEFAULT: 
  
 This Note is made pursuant to and is subject to the terms and conditions of the Credit Agreement. Any default in the
payment, prepayment or other performance of any obligation under this Note, or any Event of Default under the Credit Agreement shall constitute an “Event of Default” under this Note. 
  
 MISCELLANEOUS: 
  
 (a) Remedies. Upon the occurrence of any Event of Default, the holder
of this Note, at the holder’s option, may declare all sums of principal and accrued and unpaid interest outstanding hereunder to be immediately due and payable without presentment, demand, or any notices of any kind, including without
limitation notice of nonperformance, notice of protest, protest, notice of dishonor, notice of intention to accelerate or notice of acceleration, all of which are expressly waived by each Borrower; provided, however, that upon the occurrence
of any Event of Default described in Section 6.1 (f) and (h) of the Credit Agreement, the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Each Borrower shall pay to the holder
immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel to the extent
permissible), expended or incurred by the holder in connection with the enforcement of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any
way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with
any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to any Borrower or any other person or entity. 
  
 (b) Obligations Joint and Several. Should more than one person or
entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several. 
  
 (c) Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of Texas. 
  
 (d) Savings Clause. It is the intention of the parties to comply
strictly with applicable usury laws. Accordingly, notwithstanding any provision to the contrary in this Note, or in any contract, instrument or document evidencing or securing the payment hereof or otherwise relating hereto, including, without
limitation, the Credit Agreement (each, a “Related Document”), in no event shall this Note or any Related Document require the payment or permit the payment, taking, reserving, receiving, collection or charging of any sums constituting
interest under applicable laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified from time to time (the “Maximum Rate”). If any such excess interest is called for, contracted for, charged, taken,
reserved or received in connection with this 
  

 -5- 

 Note or any Related Document, or in any communication by Bank or any other person to Borrower or any other person, or in
the event that all or part of the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken,
reserved or received on the amount of principal actually outstanding from time to time under this Note shall exceed the Maximum Rate, then in such event it is agreed that: (i) the provisions of this paragraph shall govern and control; (ii) neither
Borrower nor any other person or entity now or hereafter liable for the payment of this Note or any Related Document shall be obligated to pay the amount of such interest to the extent it is in excess of the Maximum Rate; (iii) any such excess
interest which is or has been received by Bank, notwithstanding this paragraph, shall be credited against the then unpaid principal balance hereof or thereof, or if this Note or any Related Document has been or would be paid in full by such credit,
refunded to Borrower; and (iv) the provisions of this Note and each Related Document, and any other communication to Borrower, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other
document, to the Maximum Rate. The right to accelerate the maturity of this Note or any Related Document does not include the right to accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date
of acceleration. Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or received in connection with this Note and any Related Document which are made for the purpose of determining
whether such rate exceeds the Maximum Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of this Note or such Related Document, including all prior and
subsequent renewals and extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received by Bank. The terms of this paragraph shall be deemed to be incorporated into each Related Document. 
  
 To the extent that either Chapter 303 or 306, or both, of the Texas Finance
Code apply in determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling by using the weekly ceiling from time to time in effect, subject to Bank’s right subsequently to change such method in accordance with
applicable law, as the same may be amended or modified from time to time. 
  
 (e) Right of Setoff; Deposit Accounts. Upon and after the occurrence of an Event of Default, (i) Borrower hereby authorizes Bank, at any time and from time to time, without notice, which is hereby expressly
waived by Borrower, and whether or not Bank shall have declared this Note to be due and payable in accordance with the terms hereof, to set off against, and to appropriate and apply to the payment of, Borrower’s obligations and liabilities
under this Note (whether matured or unmatured, fixed or contingent, liquidated or unliquidated), any and all amounts owing by Bank to Borrower (whether payable in U.S. dollars or any other currency, whether matured or unmatured, and in the case of
deposits, whether general or special (except trust and escrow accounts), time or demand and however evidenced), and (ii) pending any such action, to the extent necessary, to hold such amounts as collateral to secure such obligations and liabilities
and to return as unpaid for insufficient funds any and all checks and other items drawn against any deposits so held as Bank, in its sole discretion, may elect. Borrower hereby grants to Bank a security interest in all deposits and accounts
maintained with Bank and with any other financial institution to secure the payment of all obligations and liabilities of Borrower to Bank under this Note. 
  

 -6- 

 (f) Business Purpose. Borrower represents and warrants that all loans evidenced by this Note are
for a business, commercial, investment, agricultural or other similar purpose and not primarily for a personal, family or household use. 
  
 (g) Certain Tri-Party Accounts. Borrower and Bank agree that Chapter 346 of the Texas Finance Code (which regulates certain revolving credit
accounts and revolving triparty accounts) shall not apply to any revolving loan accounts created under this Note or maintained in connection herewith. 
  
 This Note is guaranteed by the Guaranty and secured by, among other things, the Deeds of Trust, the Security Agreement and the Pledge Agreement.

RELATING TO THE INDEBTEDNESS EVIDENCED HEREBY CONSTITUTE A WRITTEN LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE

no obligation to determine whether any person requesting an advance is or has been authorized by Borrower. 
  
 (c) Application of Payments. Each payment made on this Note shall be credited first, to charges, costs and expenses, including attorneys fees and
all other amounts owing pursuant to the Credit Agreement or any other Loan Document, second to any accrued interest then remaining unpaid and third, to the outstanding principal balance hereof in the inverse order of the maturity of the principal
installments due hereunder. All payments credited to principal shall be applied first, to the outstanding principal balance of this Note which bears interest determined in relation to the Prime Rate, if any, and second, to the outstanding principal
balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest Fixed Rate Term first. 
  
 PREPAYMENT: 
  
 (a) Prime Rate. Subject to the last sentence of Paragraph (a) under Borrowing and Repayment above, Borrower may prepay principal on any portion of this Note which bears interest determined in relation to the
Prime Rate at any time, in any amount and without penalty. 
  
 (b)
LIBOR. Subject to the last sentence of Paragraph (a) under Borrowing and Repayment above, Borrower may prepay principal on any portion of this Note which bears interest determined in relation to LIBOR at any time and in the minimum amount of
One Hundred Thousand and 00/100 Dollars ($100,000.00); provided, however, that if the outstanding principal balance of such portion of this Note is less than said amount, the minimum prepayment amount shall be the entire outstanding principal
balance thereof. In consideration of Bank providing this prepayment option to Borrower, or if any such portion of this Note shall become due and payable at any time prior to the last day of the Fixed Rate Term applicable thereto, Borrower shall pay
to Bank immediately upon demand a fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such Fixed Rate Term matures, calculated as follows for each such month: 

 

	 	(i)	Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until
the last day of the Fixed Rate Term applicable thereto. 

  

	 	(ii)	Subtract from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such Fixed
Rate Term at LIBOR in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid. 

  

	 	(iii)	If the result obtained in (ii) for any month is greater than zero, discount that difference by LIBOR used in (ii) above. 

  

 -4- 

 Borrower acknowledges that prepayment of such amount may result in Bank incurring additional costs, expenses and/or
liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. Each Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of
the prepayment costs, expenses and/or liabilities of Bank. 
  
 Upon termination of
the Line of Credit for whatever reason, Borrower shall prepay all amounts owing under this note and the Line of Credit Note. 
  
 EVENTS OF DEFAULT: 
  
 This Note is made pursuant to and is subject to the terms and conditions of the Credit Agreement. Any default in the payment, prepayment or other
performance of any obligation under this Note, or any Event of Default under the Credit Agreement, shall constitute an “Event of Default” under this Note. 
  
 MISCELLANEOUS: 
  
 (a) Remedies. Upon the occurrence of any Event of Default, the holder of this Note, at the holder’s option, may declare all sums of principal
and accrued and unpaid interest outstanding hereunder to be immediately due and payable without presentment, demand, or any notices of any kind, including without limitation notice of nonperformance, notice of protest, protest, notice of dishonor,
notice of intention to accelerate or notice of acceleration, all of which are expressly waived by each Borrower; provided, however, that upon the occurrence of any Event of Default described in Section 6.1(e), (f) and (h) of the Credit
Agreement, the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Each Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs
and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel to the extent permissible), expended or incurred by the holder in connection with the enforcement
of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory
relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any Borrower or any other person or entity. 
  
 (b) Obligations Joint and Several. Should more than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall
be joint and several. 
  
 (c) Governing Law. This Note
shall be governed by and construed in accordance with the laws of the State of Texas. 
  
 (d) Savings Clause. It is the intention of the parties to comply strictly with applicable usury laws. Accordingly, notwithstanding any provision to the contrary in this Note, or in any contract, instrument or
document evidencing or securing the payment hereof or otherwise relating hereto, including, without limitation, the Credit Agreement (each, a “Related 
  

 -5- 

 Document”), in no event shall this Note or any Related Document require the payment or permit the payment, taking,
reserving, receiving, collection or charging of any sums constituting interest under applicable laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified from time to time (the “Maximum Rate”). If
any such excess interest is called for, contracted for, charged, taken, reserved or received in connection with this Note or any Related Document, or in any communication by Bank or any other person to Borrower or any other person, or in the event
that all or part of the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved or
received on the amount of principal actually outstanding from time to time under this Note shall exceed the Maximum Rate, then in such event it is agreed that: (i) the provisions of this paragraph shall govern and control; (ii) neither Borrower nor
any other person or entity now or hereafter liable for the payment of this Note or any Related Document shall be obligated to pay the amount of such interest to the extent it is in excess of the Maximum Rate; (iii) any such excess interest which is
or has been received by Bank, notwithstanding this paragraph, shall be credited against the then unpaid principal balance hereof or thereof, or if this Note or any Related Document has been or would be paid in full by such credit, refunded to
Borrower; and (iv) the provisions of this Note and each Related Document, and any other communication to Borrower, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the
Maximum Rate. The right to accelerate the maturity of this Note or any Related Document does not include the right to accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date of acceleration.
Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or received in connection with this Note and any Related Document which are made for the purpose of determining whether such rate
exceeds the Maximum Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of this Note or such Related Document, including all prior and subsequent
renewals and extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received by Bank. The terms of this paragraph shall be deemed to be incorporated into each Related Document. 
  
 To the extent that either Chapter 303 or 306, or both, of the Texas Finance
Code apply in determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling by using the weekly ceiling from time to time in effect, subject to Bank’s right subsequently to change such method in accordance with
applicable law, as the same may be amended or modified from time to time. 
  
 (e) Right of Setoff; Deposit Accounts. Upon and after the occurrence of an Event of Default, (i) Borrower hereby authorizes Bank, at any time and from time to time, without notice, which is hereby expressly
waived by Borrower, and whether or not Bank shall have declared this Note to be due and payable in accordance with the terms hereof, to set off against, and to appropriate and apply to the payment of, Borrower’s obligations and liabilities
under this Note (whether matured or unmatured, fixed or contingent, liquidated or unliquidated), any and all amounts owing by Bank to Borrower (whether payable in U.S. dollars or any other currency, whether matured or unmatured, and in the case of
deposits, whether general or special (except trust and escrow accounts), time or demand and however evidenced), and (ii) pending any such action, to the extent necessary, to hold such amounts as collateral to secure such obligations and 

 

 -6- 

 liabilities and to return as unpaid for insufficient funds any and all checks and other items drawn against any deposits
so held as Bank, in its sole discretion, may elect. Borrower hereby grants to Bank a security interest in all deposits and accounts maintained with Bank and with any other financial institution to secure the payment of all obligations and
liabilities of Borrower to Bank under this Note. 
  
 (f)
Business Purpose. Borrower represents and warrants that all loans evidenced by this Note are for a business, commercial, investment, agricultural or other similar purpose and not primarily for a personal, family or household use. 

 
 (g) Certain Tri-Party Accounts. Borrower and Bank agree that
Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts and revolving triparty accounts) shall not apply to any revolving loan accounts created under this Note or maintained in connection herewith. 
  
 This Note is guaranteed by the Guaranty and secured by, among other
things, the Deeds of Trust, the Security Agreement and the Pledge Agreement. 
  
 NOTICE: THIS NOTE, THE CREDIT AGREEMENT AND ALL OTHER DOCUMENTS RELATING TO THE INDEBTEDNESS EVIDENCED HEREBY CONSTITUTE A WRITTEN LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES RELATING TO THIS NOTE AND THE INDEBTEDNESS EVIDENCED HEREBY.
