 1. Credit Facilities 
  
 Subject to the terms and conditions set forth in this Loan Agreement and the
other Loan Documents, Bank hereby agrees to provide to Borrower the credit facilities described below (collectively, the “Credit Facilities”): 
  

1.1 Revolving Credit. Subject to the terms and conditions set forth herein, Bank agrees to lend to Borrower, on a revolving basis from time to
time during the period commencing on the Closing Date and continuing through and including 11:00 a.m. (Austin, Texas time) on the Maturity Date, such amounts as Borrower may request hereunder (the “Revolving Credit”);
provided, however, the total principal amount outstanding at any time shall not exceed the Credit Limit. If at any time the aggregate principal amount outstanding under the Revolving Credit shall exceed an amount equal to the Credit
Limit, Borrower agrees to immediately repay to Bank such excess amount, plus all accrued but unpaid interest on the amount of principal prepaid. Subject to the terms and conditions hereof, Borrower may borrow, repay and reborrow hereunder. All
advances under the Revolving Credit (individually, an “Advance” and, collectively, the “Advances”) are sometimes collectively called the “Loans”. 
  
 1.2 Letter of Credit Facility. Subject to the terms and conditions of
this Loan Agreement, Bank shall issue letters of credit for Borrower’s account (collectively, the “Letters of Credit”). Bank’s obligations under the Letters of Credit shall expire on or before thirty (30) days prior to the
Maturity Date. The aggregate amount of the Letter of Credit Obligations (as hereinafter defined) shall not exceed the Letter of Credit Limit. The obligation of Bank to issue each Letter of Credit is subject to the fulfillment to the satisfaction of
Bank of the conditions set forth elsewhere in this Loan Agreement and of the following further conditions: 
  
 (a) Borrower shall have executed and delivered to Bank a Letter of Credit Agreement; and 

 (b) Borrower shall have satisfied each of its obligations and the conditions set forth in
Section 4 of this Loan Agreement; and 
  
 (c) No Event of Default or Default shall then exist hereunder; and 
  
 (d) The aggregate amount of all of the Letters of Credit shall not exceed a sum equal to the Maximum Committed Amount, less the outstanding principal amount of all Advances under the Revolving Credit; and 

 
 (e) Borrower shall have paid the Issue Fee to Bank.

  
 2. Credit Provisions 
  
 2.1 Promissory Note. The obligation of the Borrower to repay the
Advances shall be evidenced by a promissory note (together with any renewals, extensions and increases thereof, the “Note”) duly executed by Borrower and payable to the order of Bank, in form and substance acceptable to Bank.
Interest on the Note shall accrue at the rate set forth therein. The principal of and interest on the Note shall be due and payable in accordance with the terms and conditions set forth in the Note and in this Loan Agreement. 
  
 2.2 Guarantors. As a condition precedent to Bank’s obligation to
make the Advances to Borrower and to issue the Letters of Credit, Borrower agrees to cause all of the Material Subsidiaries to each execute and deliver to Bank one or more guaranty agreements (collectively, the “Guaranty
Agreements”) in Proper Form, which Guaranty Agreements shall provide (among other things) for the unconditional guaranty of payment of the Indebtedness. Further, Borrower shall cause each Subsidiary of the Borrower which now or hereafter
exists and which is or becomes a Material Subsidiary to each execute and deliver to Bank a Guaranty Agreement in Proper Form, within ten (10) days following Bank’s demand, providing for the unconditional guaranty of the payment of the
Indebtedness. 
  
 2.3 Use of Proceeds. Subject to the
provisions of Section 4, the proceeds of the Advances under the Revolving Credit shall be available (and Borrower shall use such proceeds) for general working capital, and to fund draws received pursuant to Letters of Credit. 
  
 2.4 Default Interest. During the continuation of (a) any Default, and
(b) any Event of Default, Borrower shall pay, on demand, at Bank=s option, interest (after as well as before judgment to the extent permitted by applicable law) on the principal amount of all Advances outstanding and on all other Obligations unpaid
hereunder at a per annum rate equal to the Default Rate. 
  
 2.5
Issue Fee. In consideration of the commitment by Bank to issue any Letter of Credit, Borrower hereby agrees to pay Bank an Issue Fee equal to the Applicable L/C Percent per annum of the amount of each Letter of Credit, which fee shall be
calculated from the date of the respective Letter of Credit to the expiration date thereof. The Issue Fee as to each Letter of Credit which is issued shall be due and payable concurrently with the issuance by Bank of each such Letter of Credit. In
the event of the issuance by Bank of any extension or renewal of a Letter of Credit, an additional 

 
fee for the extension or renewal thereof shall be payable in an amount acceptable to Bank as a condition to the issuance of an extension or renewal thereof.
Nothing herein shall imply an obligation on the part of Bank to issue an extension or renewal of any Letter of Credit. 
  
 2.6 Computations and Manner of Payments. 
  
 (a) Time and Place. Borrower shall make each payment hereunder and under the other Loan Documents not later than 1:00 p.m., Austin,
Texas time, on the day when due in same day funds (by wire transfer or otherwise) to Bank at Bank’s office at 8333 Douglas Avenue, Dallas, Texas 75225, to the attention of Loan Administration. 
  
 (b) Computation of Interest. Interest on Advances,
and other amounts due under the other Loan Documents, shall be calculated at a daily rate based on a year of 360 days, with the daily rate so determined being applied for the actual number of days elapsed, but not exceeding the Maximum Lawful Rate.
Such computations shall be made including the first day but excluding the last day occurring in the period for which such interest or payment is payable. Each determination by Bank of an interest rate hereunder shall be presumptively correct absent
manifest error. All payments under the Loan Documents shall be made in United States dollars. 
  
 (c) Business Day. Whenever any payment to be made hereunder or under any other Loan Documents shall be stated to be due on a day
other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of interest or fees, if applicable. 
  
 3. Representations and Warranties. 
  
 Borrower hereby represents and warrants, and upon each request for an Advance
further represents and warrants, to Bank as follows: 
  
 3.1
Existence and Organization. Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and is authorized to transact business and is in good standing in all other jurisdictions
where the nature of its business or the ownership of its properties requires it to be so authorized. Borrower has all requisite power and authority to execute and deliver the Loan Documents. As of the Closing Date, the only Material Subsidiary is
Staktek Group L.P., a Texas limited partnership. 
  
 3.2
Binding Obligations. The execution, delivery, and performance of this Loan Agreement and all of the other Loan Documents by Borrower have been duly authorized by all necessary corporate action by Borrower, and constitute legal, valid and
binding obligations of Borrower, enforceable in accordance with their respective terms, except as limited by bankruptcy, insolvency or similar laws of general application relating to the enforcement of creditors’ rights and except to the extent
specific remedies may generally be limited by equitable principles. 
  
 3.3 No Consent. The execution, delivery and performance of this Loan Agreement and the other Loan Documents, and the consummation of the transactions contemplated hereby and thereby, do not (i) conflict with, result in a violation
of, or constitute a default under (A) any provision of its articles of incorporation or bylaws, or any agreement or other instrument binding upon Borrower, or (B) any Governmental Requirements, court decree or order applicable to Borrower, or (ii)
require the consent, approval or authorization of any third party. 

 3.4 Financial Condition. The financial statements of the Borrower dated as of September 30, 2004
and furnished to Bank (collectively, the “Prior Financial Statements”) truly disclose and fairly present the financial condition of the Borrower as of the date of each such statements. There has been no material adverse change in
the financial condition or results of operations of the Borrower subsequent to the date of the Prior Financial Statement. Except for Liabilities incurred in the normal course of business and not material in amount (either individually or in the
aggregate), Borrower has no liabilities, direct or contingent, that have arisen or been incurred or accrued subsequent to the date of the Prior Financial Statements. 
  
 3.5 Litigation. Except as set forth on Schedule 3.5 attached hereto, there are no actions, suits or
proceedings, pending or, to the knowledge of Borrower, threatened against or affecting Borrower or any Material Subsidiary, or the properties of Borrower or any Material Subsidiary, before any Governmental Authority, which, if determined adversely
to Borrower, would have a material adverse effect on the financial condition, properties, or operations of Borrower or any Material Subsidiary. 
  
 3.6 No Default. No Event of Default or Default exists at the date of this Agreement. Borrower is not in default in any respect under any
Governmental Requirement binding upon or affecting Borrower or by which any of its assets may be bound or affected, or under any agreement or other undertaking or instrument to which it is a party or by which it is bound (including, without
limitation, this Agreement), and nothing has occurred which would adversely affect in any material respect the ability of Borrower to carry on its business as now conducted and proposed to be conducted or to perform its obligations under any such
Governmental Requirement, agreement or other undertaking or agreement. 
  
 3.7 Taxes; Governmental Charges. Borrower and each Material Subsidiary have filed all federal, state and local tax reports and returns required by any law or regulation to be filed by it and have either duly paid all taxes, duties
and charges indicated due on the basis of such returns and reports, or made adequate provision for the payment thereof, and the assessment of any material amount of additional taxes in excess of those paid and reported is not reasonably expected.

  
 3.8 Patents, Trademarks, Franchises, Licenses, Etc. To
the best of Borrower’s knowledge, Borrower and each Material Subsidiary have obtained and holds all franchises, licenses, governmental permits, leases, patents, trademarks, service marks, tradenames, copyrights, and other authorizations
necessary to conduct its business as presently conducted and as proposed to be conducted (collectively, “Rights”), and each thereof is in full force and effect and no event has occurred which constitutes or, after notice or lapse of
time or both, would constitute, a default under any thereof. To the best of Borrower’s knowledge, no claim has been asserted by any Person with respect to the use of any of Rights by Borrower or any Material Subsidiary which could result in a
Material Adverse Change. To the best of Borrower’s knowledge, the use of such Rights by Borrower and each Material Subsidiary does not infringe on the rights of any Person, subject to such claims and infringements as do not, in the aggregate,
give rise to any liabilities on the part of Borrower or any Material Subsidiary which would result in a Material Adverse Change. 

 3.9 Securities Acts. Borrower has not issued any unregistered securities in violation of the
registration requirements of Section 5 of the Securities Act of 1933, as amended, or any other law and is not violating any material rule, regulation or requirement under the Securities Act of 1933, as amended, or the Securities and Exchange Act of
1934, as amended. Borrower is not required to qualify this Loan Agreement or any other Loan Document as an indenture under the Trust Indenture Act of 1939, as amended, in connection with its execution and delivery of the Notes. 
  
 3.10 Governmental Requirements. Borrower is conducting its business,
and the Material Subsidiaries are conducting their respective businesses, in compliance in all material respects with all Governmental Requirements imposed by any Governmental Authority (including without limitation, all applicable environmental
statutes, rules, regulations and ordinances). 
  
 3.11
ERISA. Each employee benefit plan as to which Borrower or any Material Subsidiary may have any liability complies in all material respects with all applicable Governmental Requirements, and (i) no “reportable event” nor
“prohibited transaction” (as defined in ERISA) has occurred with respect to any such plan, (ii) neither Borrower nor any Material Subsidiary has withdrawn from any such plan or initiated steps to do so, (iii) no steps have been taken to
terminate any such plan, and (iv) there are no unfunded liabilities other than those previously disclosed to Bank in writing. 
  
 3.12 No Margin Stock. Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of Regulations G, T, U or X of the Board of Governors of the Federal Reserve System), and no part of the proceeds of any Advance will be used to purchase or carry any such margin
stock and no part of the proceeds of any Advance will be used to extend credit to others for the purpose of purchasing or carrying any such margin stock. 
  
 3.13 Full Disclosure. Neither this Loan Agreement nor any certificate or statement or any other data furnished by Borrower in connection with the
negotiation of this Loan Agreement or the transactions contemplated hereby contains any untrue statement of a material fact or omits a material fact known to Borrower necessary to make the statements contained herein or therein not misleading.

 Either party may change the address to which such communications are to be sent by written notice to the other party as provided herein. Anything herein to the contrary
notwithstanding, requests for Advances shall not be effective until actually received by Bank. 
  
 10.5 Savings Clause. It is not the intention of any party to any of the Loan Documents to make an agreement violative of the laws of any applicable jurisdiction relating to usury. Regardless of any provision in
any of the Loan Documents, Bank shall never be entitled to receive, collect or apply, as interest on the Loans, any amount which would cause the interest rate thereon to exceed the Maximum Lawful Rate. If Bank ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall be deemed a partial repayment of principal and treated hereunder as such; and if principal is paid in full, any remaining excess shall be paid to Borrower. In determining
whether or not the interest paid or payable, under any specific contingency, would cause the interest rate to exceed the Maximum Lawful Rate, Borrower and Bank shall, to the maximum extent permitted under applicable laws, (i) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effect thereof, and (iii) amortize, prorate, allocate and spread in equal parts, the total amount of interest among all of the
Loans throughout the entire contemplated term of the Loans so that the interest rate is uniform throughout the entire term of the Loans; provided that if the Loans are paid in 

 
full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof would cause the interest
rate to exceed the Maximum Lawful Rate, Bank shall refund to Borrower the amount of such excess or credit the amount of such excess against the total principal amount owing, and, in such event, Bank shall not be subject to any penalties provided by
any laws for contracting for, charging or receiving interest in excess of the Maximum Lawful Amount. This Section 10.5 shall control every other provision of all agreements among the parties to this Loan Agreement pertaining to the
transactions contemplated by or contained in any of the Loan Documents. 
  
 10.6 Construction. This Loan Agreement and the other Loan Documents have been executed and delivered in the State of Texas, shall be governed by and construed in accordance with the laws of the State of Texas, and shall be
performable by the parties hereto in Dallas County, Texas. 
  
 10.7 Invalid Provisions. If any provision of this Loan Agreement or any of the other Loan Documents is held to be illegal, invalid or unenforceable under present or future laws, such provision shall be fully severable and the
remaining provisions of this Loan Agreement or any of the other Loan Documents shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance. 
  
 10.8 Expenses. Borrower shall pay all costs and expenses (including,
without limitation, reasonable attorneys’ fees) in connection with (i) the negotiation, documenting and closing the transactions reflected by the provisions of this Loan Agreement and any amendments, modifications, replacements and additions
hereto and to the other Loan Documents, and (ii) any action in the enforcement of Bank’s rights upon the occurrence of an Event of Default; provided, however, that the costs and expenses for which Borrower is responsible hereunder in connection
with the negotiation, documenting and closing the transactions reflected by the provisions of this Loan Agreement shall not exceed $10,000.00 and shall be subject to the following limitations: (a) travel expenses, meals, word processing time and
overtime shall not be included in the costs and expenses for which Borrower is responsible and (b) invoices shall set forth fees and expenses in reasonable detail. To the extent not prohibited by applicable law and subject to the provisions of
Section 10.5 hereof, Borrower will pay all reasonable costs and expenses and reimburse Bank for any and all reasonable expenditures of every character incurred or expended from time to time by Bank to third parties for services rendered in
connection with Bank=s exercising any of its rights and remedies under this Loan Agreement, the Note, or any of the other Loan Documents, or at law; provided, however, in the case of any matter which is contested by legal proceedings, Borrower shall
pay only such fees and costs to the extent ordered by the court. Any amount to be paid hereunder by Borrower to Bank to the extent not prohibited by applicable law, shall bear interest from the date of expenditure until reimbursed to Bank by
Borrower at the Default Rate. 
  
 10.9 Participation of the
Loans. Borrower agrees and consents to Bank’s sale or transfer, whether now or later, of one or more participation interests in the Loans to one or more purchasers, whether related or unrelated to Bank. Bank may provide, without any
limitation whatsoever, to any one or more purchasers, or potential purchasers, any information or knowledge Bank may have about Borrower or about any other matter relating to the Loan, and Borrower hereby waives any rights to privacy it may have
with respect to such matters; provided, however, that Bank shall not disclose any information which is not in the public domain to any such purchaser unless such purchaser has 

 
signed a confidentiality agreement in form acceptable to Borrower. Borrower additionally waives any and all notices of sale of participation interest, as
well as all notices of any repurchase of such participation interests. Borrower also agrees that the purchasers of any such participation interests will be considered as the absolute owners of such interests in the Loans and will have all the rights
granted under the participation agreement or agreements governing the sale of such participation interests. Borrower further waives all rights of offset or counterclaim that it may have now or later against Bank or against any purchaser of such a
participation interest and unconditionally agrees that either Bank or such purchaser may enforce Borrower’s obligation under the Loans irrespective of the failure or insolvency of any holder of any interest in the Loans. Borrower further agrees
that the purchaser of any such participation interests may enforce its interests irrespective of any personal claims or defenses that borrower may have against Bank. 
  
 10.10 JURY WAIVER. BORROWER, THE OTHER OBLIGATED PARTIES, AND BANK EACH HEREBY WAIVES THEIR RESPECTIVE RIGHTS TO A
JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY
CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. EACH PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT
KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 
  
 10.11 Entire Agreement. This Loan Agreement (together with the other Loan Documents) contains the entire agreement among the parties regarding the
subject matter hereof and supersedes all prior written and oral agreements and understandings among the parties hereto regarding same. 
  
 10.12 Conflicts. In the event any term or provision hereof is inconsistent with or conflicts with any provision of the other Loan Documents, the
terms and provisions contained in this Loan Agreement shall be controlling. 
  
 10.13 Counterparts. To facilitate execution, this Loan Agreement may be executed in any number of counterparts as may be convenient or necessary, and it shall not be necessary that the signatures of all parties
hereto be contained on any one counterpart hereof. Additionally, the parties hereto hereby covenant and agree that, for purposes of facilitating the execution of this Loan Agreement, (a) the signature pages taken from separate individually executed
counterparts of this Loan Agreement may be combined to form multiple fully executed counterparts and (b) a facsimile transmission shall be deemed to be an original signature. All executed counterparts of this Loan Agreement shall be deemed to be
originals, but all such counterparts taken together or collectively, as the case may be, shall constitute one and the same agreement. 
  
 10.14 USA Patriot Act Notification. The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001,
31 U.S.C. Section 5318:

Source at approximately 10:00 a.m. (Dallas, Texas time) on the first day of the applicable Interest Period.

in writing by Borrower which must be received by Bank before such LIBOR Rate Request will be put into effect by Bank), to be received by Bank by 12:00 o’clock Noon (Dallas, Texas time) three (3) LIBOR Business Days prior to the LIBOR Business
Day specified in the LIBOR Rate Request for the commencement of the Interest Period, evidencing (i) Borrower=s election to have (a) all or any portion of the Principal Amount which is not then the subject of an Interest Period (other than an
Interest Period which is terminating on such LIBOR Business Day), and/or (b) all or any portion of any advance of Loan proceeds which is to be made on such LIBOR Business Day, bear interest at the LIBOR Based Rate, and (iii) specifying the Interest
Period desired by Borrower in respect of the amount specified. 
  
 “LIBOR Rate Request Amount” — The amount, to be specified by Borrower in each LIBOR Rate Request, which Borrower desires to bear interest at the LIBOR Based Rate and which shall in no event be less than $100,000.00

Regulation against (i) any category of liabilities which includes deposits by reference to which the LIBOR Rate is to be determined as provided in this Note, or (ii) any category of extensions of credit or other assets which includes loans the
interest rates on which is determined on the basis of rates referred to in the definition of “LIBOR Rate” set forth above. 
  
 2. Interest. 
  
 2.1 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 Commercial Based Rate and/or one or more applicable LIBOR Based Rates (as elected in the manner specified in this Note), provided that in no event shall the Applicable Rate exceed the Maximum Lawful Rate. The foregoing notwithstanding, if at
any time the Applicable Rate exceeds the Maximum Lawful Rate, the rate of interest payable under this Note shall be limited to the Maximum Lawful Rate, but any subsequent reductions in the Commercial Based Rate or the LIBOR Based Rate, as the case
may be, shall not reduce the Applicable Rate below the Maximum Lawful Rate until the total amount of interest accrued on this Note equals the total amount of interest which would have accrued at the Applicable Rate if the Applicable Rate had at all
times been in effect. Interest prior to maturity on this Note shall be calculated at a daily rate based on a year of 360 days, with the daily rate so determined being applied for the actual number of days elapsed, provided that in no event shall the
amount or rate of interest payable hereunder exceed the Maximum Lawful Amount. Interest on the Principal Amount (whether computed at the Commercial Based Rate or at the LIBOR Based Rate) shall be payable monthly on the last day of each month
beginning the last day of April, 2005, and the remaining Principal Amount and all accrued and unpaid interest shall be due and payable in full on the Maturity Date. Any Principal Amount owing hereunder may be paid in full or in part prior to
maturity without penalty or premium, except as otherwise provided in Section 2.9 as to any Principal Amount bearing interest at the LIBOR Based Rate. 
  
 2.2 Borrower shall have the option, subject to the terms and conditions hereinafter set forth, of paying interest on the Principal Amount or portions
thereof at the Commercial Based Rate or the LIBOR Based Rate as herein provided. Except as to that portion or portions of the Principal Amount bearing interest at the LIBOR Based Rate, the Principal Amount, from time to time 

 
outstanding, shall bear interest at the Commercial Based Rate. If Borrower desires the application of the LIBOR Based Rate, it shall submit a LIBOR Rate
Request to Bank. Such LIBOR Rate Request shall be irrevocable, subject to Borrower’s right to convert the rate of interest payable hereunder with respect to any LIBOR Amount from the LIBOR Based Rate to the Commercial Based Rate as hereinafter
provided. In the event that Borrower fails to submit a LIBOR Rate Request with respect to an existing LIBOR Amount not later than 12 o’clock Noon (Dallas, Texas time) three (3) LIBOR Business Days prior to the LIBOR Business Day specified in
the LIBOR Rate Request for the commencement of the applicable Interest Period, the LIBOR Amount in question shall bear interest, commencing at the end of such Interest Period, at the Commercial Based Rate. 
  
 2.3 Bank, at its option, may honor a LIBOR Rate Request which is submitted
less than three (3) LIBOR Business Days prior to the LIBOR Business Day specified in the LIBOR Rate Request for the commencement of the applicable Interest Period; provided, however, Bank is not and shall not thereafter be bound to honor such a
request. 
  
 2.4 Any language to the contrary hereinabove
notwithstanding, there may be no more than three (3) LIBOR Based Rate elections made by Borrower outstanding at any one time during the terms of the Loan, whether or not any portion of the Principal Amount is then bearing interest at the Commercial
Based Rate. 
  
 2.5 Borrower shall pay to Bank, promptly upon
demand, such amounts as are necessary to compensate Bank for Additional Costs resulting from any Regulation which (i) subjects Bank to any tax, duty or other charge with respect to the Loan or this Note, or changes the basis of taxation of any
amounts payable to Bank under the Loan or this Note (other than taxes imposed on the overall net income of Bank or of its applicable lending office by the jurisdiction in which Bank=s principal office or such applicable lending office is located),
(ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirements relating to any extensions of credit or other assets, or any deposits with or other liabilities, of Bank, or (iii) imposes on Bank or on the interbank
LIBOR market any other condition affecting the Loan or this Note, or any of such extensions of credit or liabilities. Bank will notify Borrower of any event which would entitle Bank to compensation pursuant to this paragraph as promptly as
practicable after Bank obtains knowledge thereof and determines to request such compensation. For purposes of this paragraph, the term “Bank” shall mean and include Bank, and at Bank’s option, any present and/or future participants in
the Loan. 
  
 2.6 Without limiting the effect of the immediately
preceding paragraph, in the event that, by reason of any Regulation, (i) Bank incurs Additional Costs based on or measured by the amount of (1) a category of deposits or other liabilities of Bank which includes deposits by reference to which the
LIBOR Rate is determined as provided in this Note, and/or (2) a category of extensions of credit or other assets of Bank which includes loans the interest on which is determined on the basis of rates referred to in the definition of “LIBOR
Rate” set forth above, (ii) Bank becomes subject to restrictions on the amount of such a category of liabilities or assets which it may hold, or (iii) if it shall be unlawful or impractical for Bank to make or maintain the Loan (or any
portion thereof) at the LIBOR Based Rate, then Bank’s obligation to make or maintain the Loan (or portions thereof) at the LIBOR Based Rate (and Borrower’s right to request the same) shall be suspended and Bank shall give notice thereof to
Borrower and, upon the giving of such notice, interest payable hereunder at the LIBOR Based Rate shall be converted to the Commercial Based Rate, unless Bank may lawfully 

 
continue to maintain the Loan (or any portion thereof) then bearing interest at the LIBOR Based Rate to the end of the current Interest Period(s), at which
time the interest rate shall convert to the Commercial Based Rate. If subsequently Bank determines that such Regulation has ceased to be in effect, Bank will so advise Borrower and Borrower may convert the rate of interest payable hereunder with
respect to those portions of the Principal Amount bearing interest at the Commercial Based Rate to the LIBOR Based Rate by submitting a LIBOR Rate Request in respect thereof and otherwise complying with the provisions of this Note with respect
thereto. For purposes of this paragraph, the term “Bank” shall mean and include Bank, and at Bank’s option, any present and/or future participants in the Loan. 
  
 2.7 Determinations by Bank of the existence or effect of any Regulation on its costs of making or maintaining the Loan, or
portions thereof, at the LIBOR Based Rate, or on amounts receivable by it in respect thereof, and of the additional amounts required to compensate Bank in respect of Additional Costs, shall be presumptively correct, provided that such determinations
are made on a reasonable basis (absent manifest error). For purposes of this paragraph, the term “Bank” shall mean and include Bank, and at Bank’s option, any present and/or future participants in the Loan. 
  
 2.8 Anything herein to the contrary notwithstanding, if, at the time of or
prior to the determination of the LIBOR Based Rate in respect of any LIBOR Rate Request Amount as herein provided, Bank determines (which determination shall be presumptively correct [provided that such determination is made on a reasonable basis]
absent manifest error) that (i) by reason of circumstances affecting the interbank LIBOR market generally, adequate and fair means do not or will not exist for determining the LIBOR Based Rate applicable to an Interest Period, or (ii) the LIBOR
Rate, as determined by Bank, will not accurately reflect the cost to Bank of making or maintaining the Loan (or any portion thereof) at the LIBOR Based Rate, then Bank shall give Borrower prompt notice thereof, and the LIBOR Rate Request Amount in
question shall bear interest, or continue to bear interest, as the case may be, at the Commercial Based Rate. If at any time subsequent to the giving of such notice, Bank determines that because of a change in circumstances the LIBOR Based Rate is
again available to Borrower hereunder, Bank shall so advise Borrower and Borrower may convert the rate of interest payable hereunder from the Commercial Based Rate to the LIBOR Based Rate by submitting a LIBOR Rate Request to Bank and otherwise
complying with the provisions of this Note with respect thereto. For purposes of this paragraph, the term “Bank” shall mean and include Bank, and at Bank’s option, any present and/or future participants in the Loan. 

 
 2.9 Borrower shall pay to Bank, immediately upon request and
notwithstanding contrary provisions contained in the Loan Documents, such amounts as shall, in the conclusive judgment of Bank reasonably exercised, compensate Bank for any loss, cost or expense incurred by it as a result of (i) any payment or
prepayment, under any circumstances whatsoever, of any portion of the Principal Amount bearing interest at the LIBOR Based Rate on a date other than the last day of an applicable Interest Period, (ii) the conversion, for any reason whatsoever, of
the rate of interest payable hereunder from the LIBOR Based Rate to the Commercial Based Rate with respect to any portion of the Principal Amount then bearing interest at the LIBOR Based Rate on a date other than the last day of an applicable
Interest Period, (iii) the failure of all or a portion of an advance which was to have borne interest at the LIBOR Based Rate pursuant to a LIBOR Rate Request to be made 

 
under the Loan Agreement, or (iv) the failure of Borrower to borrow in accordance with a LIBOR Rate Request submitted by it to Bank, which amounts shall
include, without limitation, lost profits. For purposes of this paragraph, the term “Bank” shall mean and include Bank, and at Bank’s option, any present and/or future participants in the Loan. 
  
 2.10 Borrower shall have the right, from time to time, to convert the rate of
interest payable hereunder with respect to any portion of the Principal Amount not then subject to a LIBOR Rate Request, to the Commercial Based Rate, subject to the terms of this Note and provided that, in the case of a conversion from the LIBOR
Based Rate to the Commercial Based Rate, the entire amount of the LIBOR Amount in question is the subject of the conversion. 
  
 2.11 Any portion of the Principal Amount to which the LIBOR Based Rate is not or cannot, pursuant to the terms hereof, be applicable shall bear interest
at the Commercial Based Rate. 
  
 2.12 Borrower shall have the
right to prepay this Note, in whole or in part, without premium or penalty (subject, however, to the provisions of this Note), and provided that any such prepayment of principal is accompanied by (i) any interest that has accrued thereon (including
any interest payments required to be paid at the Default Rate), and (ii) any other sums that may be payable hereunder, and provided further that any such prepayment of any portion of the Note then subject to the LIBOR Based Rate shall be accompanied
by an amount equal to any losses, costs or expenses incurred by Bank, as Bank shall determine, in connection with such prepayment. 
  
 2.13 All payments of principal shall be credited first against Principal Amounts bearing interest at the Commercial Based Rate and then toward the payment
of LIBOR Amounts. Payments of LIBOR amounts shall be applied in such manner as Borrower shall select; provided, however, that Borrower shall select LIBOR Amounts to be repaid in a manner designed to minimize any losses incurred by virtue of such
payment. If Borrower shall fail to select the LIBOR Amounts to which such payments are to be applied, or if an event of default has occurred hereunder or in any other document executed in connection herewith and is continuing at the time of payment,
then Bank shall be entitled to apply the payment to such LIBOR Amounts in the manner it deems appropriate. Borrower shall compensate Bank for any losses incurred by virtue of any payment of those portions of the Loan accruing interest at the LIBOR
Based Rate prior to the last day of the relevant Interest Period, which compensation shall be determined in accordance with the provisions set forth in this Note, and any payment received pursuant to this paragraph shall be applied first to losses
incurred by Bank by reason of such payment. 
  
 2.14 If an Event
of Default shall occur, interest on the Principal Amount shall, at the option of Bank, immediately and without notice to Borrower, be converted to the Commercial Based Rate. The foregoing provision shall not be construed as a waiver by Bank of its
right to pursue any other remedies available to it under the Loan Agreement or any of the Collateral Agreements or any other instrument evidencing or securing the Loan, nor shall it be construed to limit in any way the application of the Default
Rate. 
  
 2.15 Anything to the contrary contained in this Note
notwithstanding, at the option of the holder of this Note and upon notice to the undersigned at any time after the occurrence of an Event of Default, 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 Lawful Rate. 
  
 2.16 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
undersigned 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 Bank 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. 
  
 3. Reborrowing Principal. Borrower may
borrow and reborrow funds hereunder from time to time prior to the Maturity Date, provided (i) no Default or Event of Default shall have occurred, and (ii) the principal amount outstanding hereunder shall not exceed the Revolving Credit Limit.

  
 4. Jurisdiction; Venue; Applicable Law. Borrower agrees
and consents to the jurisdiction of the District Courts of Dallas County, Texas and of the United States District Court for the Northern District of Texas (Dallas Division) and acknowledge that such courts shall constitute proper and convenient
forums for the resolution of any actions between Borrower and Bank with respect to the subject matter hereof and agrees that such courts shall be the sole and exclusive forums for the resolution of any actions between Borrower and Bank with respect
to the subject matter hereof, except that any suit to foreclose any lien which secures the payment hereof may be brought by Bank in the county or district where the property subject to such lien is located. This Note shall be governed by and
construed in accordance with the applicable laws of the United States of America and the laws of the State of Texas, except that Chapter 346 of the Texas Finance Code shall not apply to this Note. 
  
 5. Events of Default. If Event of Default shall occur for any reason
whatsoever (and whether such occurrence shall be voluntary or involuntary or come about or be effected by operation of law pursuant to or in compliance with any judgment, decree or order of any court, or any order, rule or regulation of any
administrative or governmental body, or otherwise) then, and in such event, and at any time thereafter, the holder of this Note may, at its option without demand or notice to Borrower which Borrower expressly waives (except as specifically otherwise
provided herein or in any other Loan Document) declare the outstanding principal and accrued interest owing under this Note to be immediately due and payable, whereupon the entire unpaid principal and accrued interest of this Note shall forthwith
become and be due and payable. In the event default is made in the prompt payment of this Note when due or declared due, and the same is placed in the hands of an attorney for collection, or suit is brought on same, or the same is collected through
probate, bankruptcy or other judicial proceedings, then Borrower agrees and promises to pay reasonable attorney’s fees and costs of collection in addition to the amount of principal and interest owing hereon. 
  
 6. General Waivers. Except as otherwise expressly set forth in any
other Loan Document, Borrower and all of the Obligated Parties severally waive presentment for payment, 

 
demand, notice of intent to accelerate, notice of acceleration, protest and notice of protest, and of dishonor, diligence in collecting and the bringing of
suit against any other party, and agree to all renewals, extensions, partial payments, releases, subordinations and substitutions of security, in whole or in part, with or without notice, before or after maturity. The failure by Bank to exercise any
of its rights, remedies, recourses, or powers upon the occurrence of one or more of the Events of Default shall not constitute a waiver of the right to exercise the same or any other right, remedy, recourse, or power at any subsequent time in
respect to the same or any other of the Events of Default. The acceptance by Bank of any payment hereunder which is less than payment in full of all amounts due and payable at the time of such payment shall not constitute a waiver of the right to
exercise any of Bank’s rights, remedies, recourses, or powers at that time, or any subsequent time, or nullify any prior exercise of any such right, remedy, recourse or power without the written consent of Bank, except as and to the extent
otherwise required by applicable law. 
  
 7. Reduction in
Interest. It is the intent of Bank and Borrower 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, Bank and Borrower
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 Lawful Rate; neither Borrower 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 Lawful 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. Bank, 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 of this Note 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 Lawful Rate, Bank or other holder of this Note shall, at its option, either refund to Borrower 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 Bank 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 be, upon such determination, at the option of Bank or other holder of this Note, either immediately returned to Borrower 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, Borrower acknowledges that it believes the Loan evidenced by this Note 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 Bank or other holder of this Note notice of such condition and Borrower agrees that Bank 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. 

 8. Set Off. If the unpaid principal amount of this Note, interest accrued hereon or any other
amount owing by Borrower hereunder or under any of the other Loan Documents shall have become due and payable (by acceleration or otherwise), Bank shall have the right, in addition to all other rights and remedies available to it, without notice to
Borrower, to set off against and to appropriate and apply to such due and payable amounts any debt owing to any one or more of Borrower, and any other funds held by Bank in any manner for the account of any one or more of Borrower. Such right shall
exist whether or not Bank shall have given notice or made any demand hereunder, whether or not such debt owing to or funds held for the account of any one or more of Borrower is or are matured or unmatured, and regardless of the existence or
adequacy of any collateral, guaranty or any other security, right or remedy available to Bank. Borrower hereby consent to and confirm the foregoing arrangements and confirm Bank’s rights of set off. Nothing in this Note or in any of the other
Loan Documents shall be deemed a waiver or prohibition of or restriction on Bank’s rights of set off. 
  
 9. Financial Accommodation Under Bankruptcy Code. Bank’s obligation to make any loan or advance hereunder shall be deemed to be pursuant to a
contract to make a loan or extend debt financing or financial accommodations to Borrower within the meaning of Subsections 365(c)(2) and 365(e)(2)(B) of the Bankruptcy Code of the United States of America. 
  
 THIS NOTE AND THE OTHER LOAN DOCUMENTS EXECUTED ON OR PRIOR TO THE DATE
HEREOF REPRESENT 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.
