(ii) conduct field exams of the Borrowers’ business, (iii) take copies and extracts from the Borrowers’ books and records and inspect the Borrowers’ facility, (iv) conduct on-site monitoring thereof, and (v) obtain
information requested by the Lender as to such matters relating to the Borrowers’ business operations. The Borrowers shall (and shall cause) each of their officers and employees to cooperate with such efforts by the Lender, and its agents and
advisors. Borrowers agree that the costs, fees and expenses of Lender, its agents, appraisers and advisors under this Section shall constitute a Loan hereunder that shall be promptly paid and reimbursed by Borrowers. 
 (o) Consultant. Upon Lender’s request, Borrowers shall provide a consultant that has been engaged by Lender or its
counsel (the “Consultant”), with access to the assets, operations, books, records, employees, officers and financial advisors of the Borrowers and otherwise fully cooperate with the Consultant. Borrowers agree that the costs, fees
and expenses of the Consultant shall constitute a Loan hereunder that shall be promptly paid and reimbursed by the Borrowers.

satisfactory to Lender.

promptly (not later than the second Business Day after such receipt) deposit the same into such Deposit Account. Schedule 4.1(p) sets forth all Deposit Accounts and any other investment or securities accounts maintained by Borrowers. Each
Borrower shall take all actions necessary to establish Lender’s control of each such Deposit Account and other accounts (other than an account exclusively used for payroll, payroll taxes or employee benefits), including, without limitation,
entering into Deposit Account 

  

 14 








 
Control Agreements (in form and substance acceptable to Lender). Borrowers shall be the sole account holders of each Deposit Account and any such other
securities or investment account and shall not allow any other Person (other than Lender) to have control (as defined in Article 9 of the UCC) over a Deposit Account, investment or securities account or any property deposited therein. Each Borrower
shall promptly notify Lender of any opening or closing of a Deposit Account. Each Borrower authorizes and directs each bank and other depositories to deliver to Lender (including by delivery of funds on a daily basis) all balances in any Deposit
Account maintained by such Borrower, without inquiry into the authority or right of Lender to make such requests. 
 Subsidiaries.
No subsidiary of NATK (except TTT and TieTek) shall conduct (and Borrowers shall not permit any such subsidiary to conduct) any business or activity other than those incidental to its corporate existence or own (and Borrowers shall not permit
any such subsidiary to own) any material assets.

Property Security Agreement; and (ii) cumulatively to exercise all other rights, options and privileges provided by law.

 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. 
  

 19 








 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 Borrowers fail 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 Borrowers. Anything to the contrary herein notwithstanding, no Borrower shall have any 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 Borrowers 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 

  

 20 








 
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. BORROWERS HEREBY IRREVOCABLY SUBMIT 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 Intellectual Property Security Agreement. The provisions of this Agreement are not intended to supersede the provisions of the Deed of Trust, the Security Agreement, or the Intellectual Property 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 Borrowers 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 Borrowers in favor of Lender to contract in strict compliance with applicable usury law. In furtherance thereof, Lender and Borrowers 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 Borrowers 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 Borrowers 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 Borrowers 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 Borrowers
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
Borrowers or credited against the principal balance of the Note 

  

 21 








 
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, each Borrower acknowledges that it believes the Loan to be non-usurious and agrees that if, at any time, any Borrower should have reason to believe, that the Loan is in
fact usurious, such Borrower will give Lender notice of such condition and each 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 [Intentionally
Omitted.] 
 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

the address and in the manner provided herein. 
 9.15 Legal Proceedings. Lender shall have the right to commence, appear in,
or to defend any action or 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
Borrowers to Lender upon demand. 
 9.16 [Intentionally Omitted.] 
 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 Borrowers and any of its principals. In the event of such sale
of participation or assignment, Borrowers will agree to such modifications to this Agreement as will facilitate such sale of participation or assignment. Neither the shareholders, nor the trustees of a real estate investment trust assignee shall be
personally liable for the obligations of such trust and Borrowers will agree to look solely to the trust property for the payment of any claim hereunder. Borrowers acknowledge 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 Borrowers’ consent, and that no consent or agreement by Borrowers 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 Borrowers. 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 Borrowers. Further, this Agreement shall not be deemed to create a fiduciary relationship between Lender and Borrowers. 
  

 23 








 9.19 Agent. Lender and its successors and assigns hereby (i) designate and appoint
Opus, 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 Opus 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. Opus, 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. Borrowers acknowledge that Lender and its successors and assigns transfer and assign to Opus 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. Borrowers 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 evidence the appointment and designation of Opus as agent for Lender and
other financial institutions from time to time party hereto and to the other Loan Documents. 
 9.20 Survival of Covenants. All
covenants of either party contained herein shall continue and survive until the Loan has been fully paid in cash and discharged. 
 9.21
Time Is of the Essence. Time is of the essence of this Agreement. 
 9.22 Waiver of Judicial Procedural
Matters. BORROWERS HEREBY EXPRESSLY AND UNCONDITIONALLY WAIVE, IN CONNECTION WITH ANY SUIT, ACTION OR PROCEEDING 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
Borrowers from instituting or maintaining a separate action against Lender with respect to any asserted claim. 
 9.23 Nature and
Extent of Each Borrower’s Liability. 
 9.23.1 Joint and Several Liability. Each Borrower agrees that it is
jointly and severally liable for, and absolutely and unconditionally guarantees to Lender the prompt payment and performance of, all Loans and all agreements under the Loan Documents. Each Borrower agrees that its guaranty obligations hereunder
constitute a continuing guaranty of payment and performance and not of collection, that such obligations shall not be discharged until payment in full in cash of all Loans, and that such obligations are absolute and unconditional, irrespective of
(a) the genuineness, validity, regularity, enforceability, subordination or any future modification of, or change in, any Loans or Loan Document, or any other document, instrument or agreement to which any Borrower is or may become a party or
liable; (b) the absence of any action to enforce this Agreement (including this Section) or any other Loan Document, or any waiver, consent or indulgence of any kind by Lender with respect thereto; (c) the existence, value or condition of,
or failure to perfect a Lien or to preserve rights against, any security or guaranty for the Loans or any action, or the absence of any action, by Lender in respect thereof (including the release of any security or guaranty); (d) the insolvency
of any Borrower; (e) any election by 

  

 24 








 
Lender in an Insolvency Proceeding for the application of Section 1111(b)(2) of the Bankruptcy Code; (f) any borrowing or grant of a Lien by
any other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy Code or otherwise; (g) the disallowance of any claims of Lender against any Borrower for the repayment of any Loans under Section 502 of the
Bankruptcy Code or otherwise; or (h) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, except payment in full in cash of all Loans. 
 9.23.2 Waivers. 
 9.23.2.1 Each Borrower expressly waives all rights that it may have now or in the future under any statute, at common law, in equity or otherwise, to compel Lender to marshal assets or to proceed against any Borrower, other Person or
security for the payment or performance of any Loans before, or as a condition to, proceeding against such Borrower. It is agreed among each Borrower and Lender that the provisions of this Section are of the essence of the transaction contemplated
by the Loan Documents and that, but for such provisions, Lender would decline to make the Loans. Notwithstanding anything to the contrary in any Loan Document, and except as set forth in Section 9.23.3, each Borrower expressly waives all
rights at law or in equity to subrogation, reimbursement, exoneration, contribution, indemnification or set off, as well as all defenses available to a surety, guarantor or accommodation co-obligor. Each Borrower acknowledges that its guaranty
pursuant to this Section is necessary to the conduct and promotion of its business, and can be expected to benefit such business. 
 9.23.2.2 Lender may, in its discretion, pursue such rights and remedies as they deem appropriate, including realization upon collateral by judicial foreclosure or non-judicial sale or enforcement, without affecting any rights and remedies
under this Section 9.23. If, in the exercise of any rights or remedies, Lender shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against any Borrower or any other Person, whether because of
any applicable laws pertaining to “election of remedies” or otherwise, each Borrower consents to such action by Lender and waives any claim based upon such action, even if the action may result in loss of any rights of subrogation that any
Borrower might otherwise have had but for such action. Any election of remedies that results in denial or impairment of the right of Lender to seek a deficiency judgment against any Borrower shall not impair any other Borrower’s obligation to
pay the full amount of the Loans. Each Borrower waives all rights and defenses arising out of an election of remedies, such as nonjudicial foreclosure with respect to any security for the Loans, even though that election of remedies destroys such
Borrower’s rights of subrogation against any other Person. If Lender bids at any foreclosure or trustee’s sale or at any private sale, Lender may bid all or a portion of the Loans and the amount of such bid need not be paid by 

  

 25 








 
Lender but shall be credited against the Loans. The amount of the successful bid at any such sale, whether Lender or any other Person is the successful
bidder, shall be conclusively deemed to be the fair market value of the collateral, and the difference between such bid amount and the remaining balance of the Loans shall be conclusively deemed to be the amount of the Loans guaranteed under this
Section 9.23, notwithstanding that any present or future law or court decision may have the effect of reducing the amount of any deficiency claim to which Lender might otherwise be entitled but for such bidding at any such sale.

 9.23.3 Extent of Liability; Contribution. 
 9.23.3.1 Notwithstanding anything herein to the contrary, each Borrower’s liability under this Section 9.23 shall be
limited to the greater of (i) all amounts for which such Borrower is primarily liable, as described below, and (ii) such Borrower’s Allocable Amount (as defined below). 
 9.23.3.2 If any Borrower makes a payment under this Section 9.23 of any Loans (other than amounts for which such Borrower is
primarily liable) (a “Guarantor Payment”) that, taking into account all other Guarantor Payments previously or concurrently made by any other Borrower, exceeds the amount that such Borrower would otherwise have paid if each Borrower
had paid the aggregate Loans satisfied by such Guarantor Payments in the same proportion that such Borrower’s Allocable Amount bore to the total Allocable Amounts of all Borrowers, then such Borrower shall be entitled to receive contribution
and indemnification payments from, and to be reimbursed by, each other Borrower for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment. The “Allocable
Amount” for any Borrower shall be the maximum amount that could then be recovered from such Borrower under this Section 9.23 without rendering such payment voidable or avoidable under Section 548 of the Bankruptcy
Code or under any applicable state fraudulent transfer or conveyance act, or similar statute or common law. 
 9.23.3.3
Nothing contained in this Section 9.23 shall limit the liability of any Borrower to pay Loans made directly or indirectly to that Borrower (including Loans advanced to any other Borrower and then re-loaned or otherwise transferred to, or
for the benefit of, such Borrower), and all accrued interest, fees, expenses and other related Loans with respect thereto, for which such Borrower shall be primarily liable for all purposes hereunder. Lender shall have the right, at any time in its
discretion, to condition the Loans upon a separate calculation of borrowing availability for each Borrower and to restrict the disbursement and use of such Loans to such Borrower. 
  

 26 








 9.23.4 Joint Enterprise. 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 the Loans 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. 
 9.23.5 Subordination. Each Borrower hereby subordinates any claims it may have as a result of this Section 9.23, including any
right of payment, subrogation, contribution and indemnity, that it may have at any time against any other Borrower, howsoever arising, to the payment in full in cash of all Loans. 
 9.24 Subordination. Lender hereby acknowledges that the Lender (as such term is defined in that certain Construction Loan Agreement
dated as of August 5, 2004 by and between such Lender and Borrowers (the “Construction Loan Agreement”); such Lender is referred to herein as the “First Lien Lender”) has been granted Liens upon certain Assets
of Borrowers to secure the Loans (under and as defined in the Construction Loan Agreement; such Loans are referred to herein as the “Senior Indebtedness”). The Liens of the First Lien Lender on such Assets, to the extent such Liens
secure Senior Indebtedness, are and shall be senior and prior in right to the Liens of the Lender on the Assets, and such Liens of the Lender on the Assets are and shall be junior and subordinate to the Liens of the First Lien Lender, to the extent
such Liens secure Senior Indebtedness. Except with respect to proceeds of such Assets securing the Senior Indebtedness, this Agreement shall not subordinate payments of the Loans.
