 (a) Borrower agrees that the occurrence of such event of
default shall constitute a default under each of the Loan Documents, thereby entitling Lender (i) to exercise any of the various remedies therein provided including the acceleration of the indebtedness evidenced by the Note and the foreclosure of
the Deed of Trust, the Security Agreement, and the Patent Security Agreement; and (ii) cumulatively to exercise all other rights, options and privileges provided by law. 

 (b) Lender may declare all indebtedness secured by the Deed of Trust, the Security

indebtedness at any time owing by Lender to or for the credit or the account of Borrower, against any and all of the indebtedness of Borrower evidenced by the Note or this Agreement and/or secured by the Deed of Trust, the Security Agreement, and
the Patent Security Agreement, irrespective of whether or not Lender shall have made any demand under this Agreement or the Note and although such indebtedness may be unmatured. Lender agrees to notify Borrower promptly after any such set-off and
application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of Lender under this subsection are in addition to any other rights and remedies (including, without limitation,

by Lender and any money so paid by Lender shall be an advance against the Note and shall bear interest from the date of making such payment until paid at the Default Rate (as defined in the Note) and shall be part of the indebtedness secured by the
Deed of Trust, the Security Agreement, and the Patent Security Agreement, and Lender, upon making any such payment, shall be subrogated to all rights of the person, corporation or body politic receiving such payment.

 ARTICLE IX 
  
 GENERAL CONDITIONS 
  
 9.1. Rights of Third Parties. All conditions of Lender’s obligations hereunder, including the obligation to make advances, are imposed solely and
exclusively for the benefit of Lender and its successors and assigns and no other person shall have standing to require satisfaction of such conditions in accordance with their terms or be entitled to assume that Lender will make advances or refuse
to make advances in the absence of strict compliance with any or all thereof and no other person shall, under any circumstances, be deemed to be a beneficiary of such conditions, any and all of which may be freely waived in whole or in part by
Lender at any time if in its sole discretion it deems it desirable to do so. 
  
 9.2. Waivers. No waiver of or consent to any departure from any provision hereof shall be effective unless in writing and signed by Lender and shall be effective only in the specific instance for the purpose for which
given and to the extent specified in such writing. No advance of Loan proceeds hereunder shall constitute a waiver of any of the conditions to Lender’s obligation to make further advances nor, in the event Borrower fails to satisfy any such
condition, shall any advance have the effect of precluding Lender from thereafter declaring such failure to be an event of default. No waiver of any default hereunder shall affect or constitute a waiver of any later default. No delay or omission of
Lender to exercise any right or remedy upon the happening of any event of default shall impair any such right or remedy or be deemed to be a waiver of such event of default. 
  
 9.3. Evidence of Satisfaction of Conditions. Any condition of this Agreement which requires the submission of evidence of
the existence or nonexistence of a specified fact or facts implies as a condition the existence or nonexistence, as the case may be, of such fact or facts, and Lender shall, at all times, be free independently to establish to its reasonable
satisfaction and in its discretion such existence or nonexistence. 

 9.4. Assignment by Borrower. Anything to the contrary herein notwithstanding, Borrower shall have no
right to assign its rights hereunder or the proceeds of the Loan without the written consent of Lender and any such assignment or purported assignment shall, at Lender’s option, relieve Lender from all further obligations hereunder and shall
constitute a default under this Agreement. 
  
 9.5. Successors and
Assigns Included in Parties. Whenever in this Agreement one of the parties hereto is named or referred to, the heirs, legal representatives, successors and assigns of such party shall be included and all covenants and agreements contained in this
Agreement by or on behalf of the Borrower or by or on behalf of Lender shall bind and inure to the benefit of their respective heirs, legal representatives, successors and assigns, whether so expressed or not. 
  
 9.6. Exercise of Rights and Remedies. All rights and remedies of Lender
hereunder or under the Note or under any other Loan Document shall be separate, distinct and cumulative and no single, partial or full exercise of any right or remedy shall exhaust the same or preclude Lender from thereafter exercising in full or in
part the same right or remedy or from concurrently or thereafter exercising any other right or remedy which Lender may have hereunder, under the Note or any other Loan Document, or at law or in equity, and each and every such right and remedy may be
exercised at any time or from time to time. 
  
 9.7. Headings. The
headings of the sections and subsections of this Agreement are for the convenience of reference only, are not to be considered a part hereof and shall not limit or otherwise affect any of the terms hereof. 
  
 9.8. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE
PARTIES’ RIGHTS AND OBLIGATIONS HEREUNDER AND THEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO TEXAS’ PRINCIPLES OF CONFLICTS OF LAW)
AND THE LAW OF THE UNITED STATES APPLICABLE TO TRANSACTIONS IN SUCH STATE. BORROWER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS, OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO ANY OF THE LOAN DOCUMENTS. 
  
 9.9. Supplement
to Deed of Trust, Security Agreement, and Patent Security Agreement. The provisions of this Agreement are not intended to supersede the provisions of the Deed of Trust, the Security Agreement, or the Patent Security Agreement, but shall be construed
as supplemental thereto. In the event of any inconsistency between the provisions hereof and said documents, it is intended that, during the applicability of this Agreement, this Agreement shall be controlling. 

 9.10. Usury. Lender and Borrower intend in the execution of the Note, this Agreement and all other
instruments now or hereafter securing the Note or executed in connection therewith or under any other written or oral agreement by Borrower in favor of Lender to contract in strict compliance with applicable usury law. In furtherance thereof, Lender
and Borrower stipulate and agree that none of the terms and provisions contained in the Note, this Agreement or any other instrument securing the Note or executed in connection herewith, or in any other written or oral agreement by Borrower in favor
of Lender, shall ever be construed to create a contract to pay for the use, forbearance or detention of money, interest at a rate in excess of the maximum interest rate permitted to be charged by applicable law; neither Borrower nor any endorsers or
other parties now or hereafter becoming liable for payment of the Note or the other indebtedness secured by the Loan Documents shall ever be obligated or required to pay interest on the Note or on indebtedness arising under any instrument securing
the Note or executed in connection therewith, or in any other written or oral agreement by Borrower in favor of Lender, at a rate in excess of the maximum interest that may be lawfully charged under applicable law; and that the provisions of this
section shall control over all other provisions of the Note, this Agreement and any other instruments now or hereafter securing the Note or executed in connection herewith or any other oral or written agreements which may be in apparent conflict
herewith. Lender expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of the Note is accelerated. If the maturity of the Note shall be accelerated for any reason or if the
principal of the Note is paid prior to the end of the term of the Note, and as a result thereof the interest received for the actual period of existence of the Loan exceeds the applicable maximum lawful rate, Lender shall, at its option, either
refund to Borrower the amount of such excess or credit the amount of such excess against the principal balance of the Note then outstanding and thereby shall render inapplicable any and all penalties of any kind provided by applicable law as a
result of such excess interest. In the event that Lender shall contract for, charge or receive any amounts and/or any other thing of value which are determined to constitute interest which would increase the effective interest rate on the Note or
the other indebtedness secured by the Loan Documents to a rate in excess of that permitted to be charged by applicable law, an amount equal to interest in excess of the lawful rate shall, upon such determination, at the option of Lender, be either
immediately returned to Borrower or credited against the principal balance of the Note then outstanding or the other indebtedness secured by the Loan Documents, in which event any and all penalties of any kind under applicable law as a result of
such excess interest shall be inapplicable. By execution of this Agreement, Borrower acknowledges that it believes the Loan to be non-usurious and agrees that if, at any time, Borrower should have reason to believe, that the Loan is in fact
usurious, it will give Lender notice of such condition and Borrower agrees that Lender shall have ninety (90) days after receipt of such notice in which to make appropriate refund or other adjustment in order to correct such condition if in fact
such exists. The term “applicable law” as used in this section shall mean the laws of the state of Texas or the laws of the United States, whichever laws allow the greater rate of interest, as such laws now exist or may be changed or
amended or come into effect in the future. 
  
 9.11. Invalid
Provisions to Affect No Others. If fulfillment of any provision hereof or any transaction related hereto at the time performance of such provisions shall be due, shall involve transcending the limit of validity prescribed by law, then ipso facto the
obligation to 

 be fulfilled shall be reduced to the limit of such validity; and if any clause or provisions herein contained operates or
would prospectively operate to invalidate this Agreement in whole or in part, then such clause or provision only shall be held for naught, as though not herein contained, and the remainder of this Agreement shall remain operative and in full force
and effect. 
  
 9.12. Number and Gender. Whenever the singular or
plural number, masculine or feminine or neuter gender is used herein, it shall equally include the other. 
  
 9.13. Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. 
  
 9.14. Notice. Any notice or communication required or permitted hereunder shall be given in writing, sent by (a) personal delivery, or (b) expedited
delivery service with proof of delivery, or (c) United States Mail, postage prepaid, registered or certified mail, addressed as follows:

proceeding purporting to affect the rights or duties of the parties hereunder or the payment of any funds, and in connection therewith pay necessary expenses, employ counsel and pay its reasonable fees. Any such expenditures shall be considered
additional advances hereunder and shall bear interest at the rate payable under the Note for installments of principal and/or interest after maturity shall be secured by the Loan Documents and shall be paid by Borrower to Lender upon demand.

  
 9.16. Assignment by Lender. Lender shall have the right to
assign any portion of this Agreement and/or the Loan and to disseminate to such lender any information it has pertaining to the Loan, including without limitation, complete and current credit information on Borrower and any of its principals. In the
event of such an assignment, Borrower will agree to such modifications to this Agreement as will facilitate such assignment, provided that such modifications will be at Lender’s expense and will not add to the obligations of Borrower. It is
understood that any assignment by Lender will not result in additional cash expense to Borrower. Neither the shareholders, nor the trustees of a real estate investment trust assignee shall be personally liable for the obligations of such trust and
Borrower will agree to look solely to the trust property for the payment of any claim hereunder. 
  
 9.17. Participations and Assignments by Lender. Lender shall have the right to assign or grant participating interests in any portion of this Agreement
and/or the Loan and to disseminate to such lender any information it has pertaining to the Loan, including without limitation, complete and current credit information on Borrower and any of its principals. In the event of such sale of participation
or assignment, Borrower will agree to such modifications to this Agreement as will facilitate such sale of participation or assignment, provided that such modifications will be at Lender’s expense and will not add to the obligations of
Borrower. It is understood that any sale of participation or assignment by Lender will not result in additional cash expense to Borrower. Neither the shareholders, nor the trustees of a real estate investment trust assignee shall be personally
liable for the obligations of such trust and Borrower will agree to look solely to the trust property for the payment of any claim hereunder. Borrower acknowledges that Lender and any successor lender may enter into a separate agreement regarding
the rights, duties and obligations of Lender and other matters pertaining thereto without Borrower’s consent, provided, that no consent or agreement by Borrower shall be required to amend, modify, change, restate, waive, supplement, discharge,
cancel or terminate any provision of this Agreement so long as no additional duties are required to be assumed by Borrower. Each successor lender shall have all of the rights and benefits with respect to the obligations, Note, collateral and/or Loan
Documents held by it as fully as if the original holder thereof, and either Lender or any successor lender may be designated as the sole agent to manage the transactions and obligations contemplated therein. 
  
 9.18. Lender Not a Joint Venturer. Notwithstanding anything to the contrary
herein contained, Lender, by entering into this Agreement or by any action taken pursuant hereto, 

 will not be deemed a partner or joint venturer with Borrower. Further, this Agreement shall not be deemed to create a
fiduciary relationship between Lender and Borrower. 
  
 9.19.
Agent. Lender and its successors and assigns hereby (i) designate and appoint Tie Investors, and its successors and assigns, to act as agent for Lender and its successors and assigns under this Agreement and all other Loan Documents; (ii)
irrevocably authorize Tie Investors to take all actions on its behalf under the provision of this Loan Agreement and all other Loan Documents; and (iii) to exercise all such powers and rights, and to perform all such duties and obligations hereunder
and thereunder. Tie Investors, on behalf of Lender, shall hold all collateral, payments of principal and interest, fees, charges and collections received pursuant to this Agreement and all other Loan Documents. Borrower acknowledges that Lender and
its successors and assigns transfer and assign to Tie Investors the right to act as Lender’s agent to enforce all rights and perform all obligations of Lender contained herein and in all of the other Loan Documents. Borrower shall within ten
(10) days after Lender’s reasonable request, take such further actions, obtain such consents and approvals and duly execute and deliver such further agreements, amendments, assignments, instructions or documents as Lender may request to

 9.20. Survival of Covenants. All covenants of either party contained herein shall continue and survive until the Loan has
been fully paid and discharged. 
  
 9.21. Time Is of the Essence.
Time is of the essence of this Agreement. 
  
 9.22. Waiver of
Judicial Procedural Matters. BORROWER HEREBY EXPRESSLY AND UNCONDITIONALLY WAIVES, IN CONNECTION WITH ANY SUIT, ACTION OR PROCEEDING BROUGHT BY LENDER IN CONNECTION WITH ANY OF THE LOAN DOCUMENTS, ANY AND EVERY RIGHT IT MAY HAVE TO (I) INJUNCTIVE
RELIEF, (II) A TRIAL BY JURY, (III) INTERPOSE ANY COUNTERCLAIM THEREIN (OTHER THAN A COMPULSORY COUNTERCLAIM) AND (IV) HAVE THE SAME CONSOLIDATED WITH ANY OTHER OR SEPARATE SUIT, ACTION OR PROCEEDING. Nothing herein contained shall prevent or
prohibit Borrower from instituting or maintaining a separate action against Lender with respect to any asserted claim. 
  
 9.23. Joint and Several Liability. Each Borrower acknowledges that it is jointly and severally liable for all of the obligations under the Loan Documents.
Each Borrower expressly understands, agrees and acknowledges that (i) Borrowers are affiliated entities by common ownership; (ii) each Borrower desires to have the availability of one common credit facility instead of separate credit facilities;
(iii) each Borrower has requested that Lender extend such a common credit facility on the terms herein provided; (iv) Lender will be lending against, and relying on a lien upon, all of each Borrower’s assets even though the proceeds of any
particular loan made hereunder may not be advanced directly to a particular Borrower; (v) each Borrower will nonetheless benefit by the making of all such loans by Lender and the availability of a single credit facility of a size greater than each
could independently warrant; and (vi) all of the representations, warranties, covenants, obligations, conditions, agreements and other terms contained in the Loan Documents shall be applicable to and shall be binding upon each Borrower.

 FOR VALUE RECEIVED,
the undersigned, NORTH AMERICAN TECHNOLOGIES GROUP, INC., a Delaware corporation, TIETEK TECHNOLOGIES, INC., a Texas corporation, and TIETEK LLC, a Delaware limited liability company (herein, collectively and jointly and severally,
“Maker”), hereby promise to pay to the order of TIE INVESTORS, LLC, a Texas limited liability company (herein sometimes called “Payee”), the principal sum of Fourteen Million Dollars ($14,000,000), or so much
thereof from time to time outstanding as shall be advanced, with interest on the unpaid balance thereof from date of advancement until maturity at the rate or rates hereinafter provided, both principal and interest payable as hereinafter provided in

 As herein provided the unpaid Principal Amount of this Note
(or portions thereof) from time to time outstanding shall bear interest prior to maturity at the Applicable Rate, provided that in no event shall the Applicable Rate exceed the Maximum Rate. Notwithstanding the foregoing, if at any time the
Applicable Rate exceeds the Maximum Rate, the rate of interest payable under this Note shall be limited to the Maximum Rate, but any subsequent reductions in the Applicable Rate shall not reduce the Applicable Rate below the Maximum Rate until the

 “Loan.” The $14,000,000 loan to be made to Maker by Payee
pursuant to the Loan Agreement and evidenced hereby.

 “Maximum Rate.” The maximum interest rate permitted under applicable law, it being understood that, if applicable law provides for a
ceiling under Chapter 301, Subchapter A of the Texas Credit Title (as may be amended from time to time), such ceiling shall be the “weekly” ceiling. 
  

“Patent Security Agreement.” An agreement of even date herewith granting to Payee a first lien on all of Maker’s intellectual
property, including, but not limited to, all trademarks, copyrights, licenses, and patents (issued and applied for) executed pursuant to and defined in the Loan Agreement.

 Maker shall have the right to prepay this Note, in whole or in part, without premium or penalty, and upon the payment of all accrued interest on the amount prepaid (and any interest which has accrued at the Default
Rate, if applicable, and other sums that may be payable hereunder) to the date so fixed. 
  
 During the Interim Loan Period, interest on the Principal Amount shall be payable quarterly in arrears commencing on the first day of the first calendar quarter following the first advance of Loan proceeds which are

date of such payment. Notwithstanding the foregoing, provided that (i) the Board of Managers or other governing body of the Maker has made a good faith determination that it is the best interest of the Maker to issue a PIK Note (as defined below) in
lieu of paying in cash the quarterly payment then due under this Note; and (ii) the Payee, in its sole discretion, agrees to accept such PIK Note, then with respect to the first six (6) quarterly installments of the Permanent Loan Period, the Maker
shall have the option to pay the accrued and unpaid interest then due on the outstanding balance of this Note as interest payable-in-kind (“PIK Interest”) by executing and delivering to Payee a promissory note evidencing the
Maker’s obligation to pay such PIK Interest (the “PIK Note”), payable to the order of Payee, duly executed and delivered by Maker and payable on terms and conditions satisfactory to Payee as set forth therein. 
  
 Notwithstanding anything to the contrary contained in this Note, at the
option of the holder of this Note and upon notice to the Maker at any time after the occurrence of a Default as defined in the Loan Agreement, from and after such notice and during the continuance of such Default, the unpaid principal of this Note
from time to time outstanding and all past due installments of interest shall, to the extent permitted by applicable law, bear interest at the Default Rate, provided that in no event shall such interest rate be more than the Maximum Rate.

  
 All interest accruing under this Note shall be calculated on
the basis of a 360-day year applied to the actual number of days in each month. The Maker shall make each payment which it owes hereunder not later than twelve o’clock, noon, Dallas, Texas, time, on the date such payment becomes due and payable
(or the date any voluntary 

 prepayment is made), in immediately available funds. Any payment received by the Payee after such time will be deemed to
have been made on the next following business day. As used herein, the term “business day” shall mean a day on which commercial banks are open for business with the public in Dallas, Texas. 
  
 This Note has been executed and delivered pursuant to the Loan Agreement
between Maker and Payee which provides for (i) the repayment of that certain bridge loan in the original principal amount of Two Million One Hundred Thousand Dollars ($2,100,000) evidenced by that certain Promissory Note dated August 15, 2003, and
executed by Maker, and Tie Investors, LLC as Payee; (ii) the reimbursement to Maker of certain amounts; and (iii) the purchase of equipment and provision of working capital for the operation of Maker’s business at its location in Marshall,
Texas, and the disbursement from time to time of the proceeds of this Note for use in paying for the costs thereof. 
  
 This Note is secured by, inter alia, the Deed of Trust of even date herewith in favor of the Trustee named therein evidencing a loan on certain real
property in Harrison County, Texas, described therein, and evidencing a security interest in certain personal property described therein, to which the Deed of Trust reference is here made for a description of the property covered thereby and the
nature and extent of the security and the rights and powers of the holder of the Note in respect of such security. Upon the occurrence of a default specified in the Deed of Trust which remains uncured beyond any applicable notice, cure or grace
period, the holder of this Note, or any part thereof, shall have the option of declaring the Principal Amount hereof and the interest accrued herein to be immediately due and payable. 
  
 This Note is also secured by the Security Agreement and the Patent Security Agreement of even date herewith evidencing a
first lien on certain tangible and intangible personal property described therein to which Security Agreement and Patent Security Agreement reference is here made for the description of the property covered thereby and the nature and extent of the
security and the rights and powers of the holder of this Note in respect of such security. Upon the occurrence of a Default, as defined in the Loan Agreement, which remains uncured beyond any applicable notice, cure or grace period, the holder of
this Note or any part thereof shall have the option of declaring the Principal Amount hereof and the interest accrued hereon to be immediately due and payable. 
  

Payee and Maker intend in the execution of this Note and all other instruments now or hereafter securing this Note to contract in strict compliance
with applicable usury law. In furtherance thereof, Payee and Maker stipulate and agree that none of the terms and provisions contained in this Note, or in any other instrument executed in connection herewith, shall ever be construed to create a
contract to pay for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate; neither Maker nor any guarantors, endorsers or other parties now or hereafter becoming liable for payment of this Note shall ever be
obligated or required to pay interest on this Note at a rate in excess of the Maximum Rate that may be lawfully charged under applicable law, and the provisions of this paragraph shall control over all other provisions of this Note and any other
instruments now or hereafter executed in connection herewith which may be in apparent conflict herewith. Payee, including each holder of this Note, expressly disavows 

 any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of this Note
is accelerated. If the maturity of this Note shall be accelerated for any reason or if the Principal Amount is paid prior to the end of the term of this Note, and as a result thereof the interest received for the actual period of existence of the
Loan exceeds the amount of interest that would have accrued at the Maximum Rate, the Payee or other holder of this Note shall, at its option, either refund to Maker the amount of such excess or credit the amount of such excess against the Principal
Amount and thereby shall render inapplicable any and all penalties of any kind provided by applicable law as a result of such excess interest. In the event that Payee or any other holder of this Note shall contract for, charge or receive any amounts
and/or any other thing of value which are determined to constitute interest which would increase the effective interest rate on this Note to a rate in excess of that permitted to be charged by applicable law, all such sums determined to constitute
interest in excess of the amount of interest at the lawful rate shall, upon such determination, at the option of the Payee or other holder of this Note, be either immediately returned to Maker or credited against the Principal Amount, in which event
any and all penalties of any kind under applicable law as a result of such excess interest shall be inapplicable. By execution of this Note, Maker acknowledges that it believes the Loan evidenced by this Note to be non-usurious and agrees that if,
at any time, Maker should have reason to believe that the Loan is in fact usurious, it will give the Payee or other holder of this Note notice of such condition and Maker agrees that the Payee or other holder shall have ninety (90) days in which to
make appropriate refund or other adjustment in order to correct such condition if in fact such exists. The term “applicable law” as used in this Note shall mean the laws of the state of Texas or the laws of the United States, whichever
laws allow the greater rate of interest, as such laws now exist or may be changed or amended or come into effect in the future. 
  
 Should the indebtedness represented by this Note or any part thereof be collected at law or in equity or through any bankruptcy, receivership, probate or
other court proceedings or if this Note is placed in the hands of attorneys for collection after default, Maker and all endorsers, guarantors and sureties of this Note jointly and severally agree to pay to the Payee or other holder of this Note in
addition to the principal and interest due and payable hereon reasonable attorneys’ and collection fees. 
  
 Except as otherwise specifically provided in the Loan Documents, Maker and all endorsers, guarantors and sureties of this Note and all other persons
obligated or to become obligated on this Note severally waive presentment for payment, demand, notice of demand and of dishonor and nonpayment of this Note, notice of intention to accelerate the maturity of this Note, protest and notice of protest,
diligence in collecting, and the bringing of suit against any other party, and agree to all renewals, extensions, modifications, partial payments, releases or substitutions of security, in whole or in part, with or without notice, before or after
maturity. 
  
 THIS NOTE AND THE OTHER LOAN DOCUMENTS AND THE
PARTIES’ RIGHTS AND OBLIGATIONS HEREUNDER AND THEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO TEXAS’ PRINCIPLES OF CONFLICTS OF LAW)
AND THE 

 LAWS OF THE UNITED STATES APPLICABLE TO TRANSACTIONS IN SUCH STATE. MAKER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE OR ANY OF THE LOAN DOCUMENTS, AND MAKER HEREBY AGREES AND CONSENTS THAT, IN ADDITION TO ANY METHODS OF
SERVICE OF PROCESS PROVIDED FOR UNDER APPLICABLE LAW, ALL SERVICE OF PROCESS IN ANY SUCH SUIT, ACTION OR PROCEEDING IN ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS (OR SUCH OTHER COUNTY IN TEXAS) MAY BE MADE BY CERTIFIED OR REGISTERED MAIL,
RETURN RECEIPT REQUESTED, DIRECTED TO MAKER AT THE ADDRESS OF MAKER FOR THE GIVING OF NOTICES UNDER THE LOAN AGREEMENT, AND SERVICE SO MADE SHALL BE COMPLETE FIVE (5) DAYS AFTER THE SAME SHALL HAVE BEEN SO MAILED.
