subsequent reduction shall not reduce the rate of interest on the Revolving Credit Advances below the Maximum Lawful Rate until the aggregate amount of interest accrued on the Revolving Credit Advances equals the aggregate amount of interest which
would have accrued on the Revolving Credit Advances if the interest rate had not been limited by the Maximum Lawful Rate. Accrued and unpaid interest on the Revolving Credit Advances shall be payable as provided in the Revolving Credit Note and on
the Termination Date.



D. Borrowing Procedure. Except
with respect to the credit sweep provisions of the Note, the Borrower shall give the Lender notice of each Revolving Credit Advance by means of an Advance Request Form containing the information required therein and delivered (by hand or by
mechanically confirmed facsimile) to the Lender no later than 1:00 p.m. (Texas time) on the Business day prior to the day on which the Revolving Credit Advance is desired to be funded, specifying

---

the requested date of the Advance. The Lender at its option may accept telephonic requests for such
Advances, provided that such acceptance shall not constitute a waiver of the Lenders right to require delivery of an Advance Request Form in connection with subsequent Advances. Any telephonic request for a Revolving Credit Advance by the
Borrower shall be promptly confirmed by submission of a properly completed Advance Request Form to the Lender, but failure to deliver an Advance Request Form shall not be a defense to payment of the Advance. The Lender shall have no liability to the
Borrower for any loss or damage suffered by the Borrower as a result of the Lenders honoring of any requests, execution of any instructions, authorizations or agreements or reliance on any reports communicated to it telephonically, by
facsimile or electronically and purporting to have been sent to the Lender by the Borrower and the Lender shall have no duty to verify the origin of any such communication or the identity or authority of the Person sending it. Subject to the terms
and conditions of this Agreement, each Revolving Credit Advance shall be made available to the Borrower by depositing the same, in immediately available funds, in an account of the Borrower designated by the Borrower maintained with the Lender at
the Principal Office.



Section 2.2 General Provisions
Regarding Interest; Etc.



A. Any outstanding principal of
any Advance and (to the fullest extent permitted by law) any other amount payable by the Borrower under this Agreement or any other Loan Document that is not paid in full when due (whether at stated maturity, by acceleration, or otherwise) shall
bear interest at the Default Interest Rate for the period from and including the due date thereof to but excluding the date the same is paid in full. Additionally, upon the occurrence of an Event of Default (and from the date of such occurrence) all
outstanding and unpaid principal amounts of all of the Obligations shall, to the extent permitted by law, bear interest at the Default Interest Rate until such time as the Lender shall waive in writing the application of the Default Interest Rate to
such Event of Default situation. Interest payable at the Default Interest Rate shall be payable from time to time on demand.



B. Computation of Interest. Interest on the Advances and all other amounts payable by the Borrower hereunder shall be computed on the basis of a
year of 360 days and the actual number of days elapsed (including the first day but excluding the last day) unless such calculation would result in a usurious rate, in which case interest shall be calculated on the basis of a year of 365 or 366
days, as the case may be.



Section 2.3 Unused Facility
Fee. The Borrower agrees to pay to the Lender an unused facility fee on the daily average unused amount of the Commitment for the period from and including the date of this Agreement to and including the Termination Date, at the rate of
one-quarter of one percent (.25%) per annum based on a 360 day year and the actual number of days elapsed. For the purpose of calculating the commitment fee hereunder, the Commitment shall be deemed utilized by the amount of all outstanding Advances
and Letter of Credit Liabilities. Accrued commitment fee shall be payable quarterly in arrears and on the Termination Date.



LOAN AGREEMENT - Page 15

Section 2.4 Use of Proceeds. The proceeds of the Revolving Credit Advances shall be used by the
Borrower (i) to refinance existing indebtedness of the Borrower, (ii) to pay fees and expenses in connection with the transactions contemplated herein, (iii) to make Permitted Acquisitions, (iv) to make Permitted Investments and (v) for working
capital in the ordinary course of business and other general corporate purposes.



Section 2.5 Letters of Credit.



A. Standby Letters of Credit. Subject to the terms and conditions of this Agreement, the Lender agrees to issue one or more Letters of Credit for the account of the Borrower from time to time from the date hereof to and including the
Revolving Credit Termination Date; provided, however, that the outstanding Letter of Credit Liabilities shall not at any time exceed the lesser of (a) Five Hundred Thousand Dollars ($500,000), (b) an amount equal to the amount of the Commitment
minus the outstanding Revolving Credit Advances, or (c) the Borrowing Base minus the outstanding Revolving Credit Advances. Each Letter of Credit shall have an expiration date not to exceed 365 days, shall not have an expiration date beyond the
Termination Date, shall be payable in Dollars, must support a transaction that is entered into in the ordinary course of the Borrowers business, must be satisfactory in form and substance to the Lender, will be subject to the payment of such
Letter of Credit fees as the Lender may require, and shall be issued pursuant to such documents and instruments executed by the Borrower (including, without limitation, the Borrowers form of letter of credit application as then in effect) as
the Lender may require.



Each payment by the
Lender pursuant to a drawing under a Letter of Credit is due and payable ON DEMAND, and at the sole option of the Lender, can be charged by the Lender as (and will be deemed to be) a Revolving Credit Advance by the Lender to the Borrower under the
Revolving Credit Note and this Agreement as of the day and time such payment is made by the Lender and in the amount of such payment.



B. Obligations Absolute. The obligation of the Borrower to reimburse the Lender for each drawing under each Letter of Credit shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:



1. any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;



2. the existence of any claim, counterclaim, set-off, defense or other
right that the Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Lender or any other Person, whether in connection
with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;



LOAN AGREEMENT - Page 16



---

3. any draft, demand, certificate or other document presented under such Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit; or



4. any payment by the Lender under such
Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the Lender under such Letter of Credit to any Person purporting to be a trustee in
bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any
proceeding under any Debtor Relief Law.



The Borrower shall promptly examine a copy of each Letter of Credit that is delivered to it and, in the event of any claim of noncompliance with the Borrowers instructions or other irregularity, the Borrower
will immediately notify the Lender. The Borrower shall be conclusively deemed to have waived any such claim against the Lender and its correspondents unless such notice is given as aforesaid.



C. Role of Lender. The Borrower agrees that, in paying any drawing
under a Letter of Credit, the Lender shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or
accuracy of any such document or the authority of the Person executing or delivering any such document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit;
provided, however, that this assumption is not intended to, and shall not, preclude the Borrowers pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Lender,
any of its Affiliates, any of the respective officers, directors, employees, agents or attorneys-in-fact of the Lender and its Affiliates, nor any of the respective correspondents, participants or assignees of the Lender shall be liable or
responsible for any of the matters described in clauses (1) through (4) of Section 2.5.B; provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the Lender, and the Lender may
be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the Lenders willful misconduct or gross
negligence or the Lenders willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing, the Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, and the Lender shall not be responsible for the validity or sufficiency
of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

D. Cash Collateral. Upon the request of the Lender, (i) if the Lender has honored any full or
partial drawing request under any Letter of Credit and such drawing has not been reimbursed on the applicable honor date or converted to an Advance, or (ii) if, as of the Termination Date, any Letter of Credit may for any reason remain outstanding
and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then outstanding amount of all Letter of Credit obligations (in an amount equal to such outstanding amount determined as of the applicable honor date or the
Letter of Credit expiration date, as the case may be). For purposes hereof, Cash Collateralize means to pledge and deposit with or deliver to the Lender, as collateral for the Letter of Credit obligations, cash or deposit account
balances pursuant to documentation in form and substance satisfactory to the Lender. Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Lender a security interest in all such cash, deposit accounts and all
balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in a blocked, non-interest bearing deposit account at the Lender.



E. Applicability of ISP98. Unless otherwise expressly agreed by the Lender and the Borrower when a Letter of Credit is issued, the rules of the
International Standby Practices 1998 published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each Letter of Credit .



F. Standby Letter of Credit Fees. The Borrower shall pay to the
Lender, an amount equal to two point two five percent (2.25%) per annum on the daily average undrawn amount of the Letter of Credit Liability from and including the date of this Agreement to and including the Revolving Credit Termination Date. The
accrued letter of credit fee shall be payable quarterly in arrears and on the Revolving Credit Termination Date. Fronting, amendment, transfer, negotiation and other fees will also be payable by the Borrower on demand for the account of the Lender
as issuing bank as determined in accordance with the Lenders then current fee policy.

deduction, or counterclaim, and free and clear of all taxes at the time and in the manner provided in the Notes. Provided no Event of Default exists, the Lender shall apply such payment first to all accrued unpaid interest, then to outstanding

Section 3.3 Additional Costs in Respect of Letters of
Credit. If as a result of any regulatory change there shall be imposed, modified, or deemed applicable any tax, reserve, special deposit, or similar requirement against or with respect to or measured by reference to Letters of Credit issued or
to be issued hereunder or the Lenders commitment to issue Letters of Credit hereunder, and the result shall be to increase the cost to the Lender of issuing or maintaining any Letter of Credit or its commitment to issue Letters of Credit
hereunder or reduce any amount receivable by the Lender hereunder in respect of any Letter of Credit (which increase in cost, or reduction in amount receivable, shall be the result of the Lenders reasonable allocation of the aggregate of such
increases or reductions resulting from such event), then, upon demand by the Lender, the Borrower agrees to pay the Lender, from time to time as specified by the Lender, such additional amounts as shall be sufficient to compensate the Lender for
such increased costs or reductions in amount. A statement as to such increased costs or reductions in amount incurred by the Lender, submitted by the Lender to the Borrower, shall be conclusive as to the amount thereof, provided that the
determination thereof is made on a reasonable basis.

modifications, renewals, extensions, and supplements thereof and thereto, including, without limitation, the reasonable
fees and expenses of legal counsel, advisors, consultants, and auditors for the Lender, (b) all costs and expenses of the Lender in connection with any Default and the enforcement of this Agreement or any other Loan Document, including, without
limitation, the reasonable fees and expenses of legal counsel, advisors, consultants, and auditors for the Lender, (c) all transfer, stamp, documentary, or other similar taxes, assessments, or charges levied by any Governmental Authority in respect
of this Agreement or any of the other Loan Documents, (d) all costs, expenses, assessments, and other charges incurred in connection with any filing, registration, recording, or perfection of any security interest or Lien contemplated by this

observing, collecting, examining, auditing, appraising, selling, liquidating, or otherwise disposing of the Collateral or other assets of the Borrower. Anything herein to the contrary notwithstanding, the obligation of the Borrower to reimburse
professional fees hereunder shall be conditioned upon the provision to the Borrower of a reasonably detailed statement of services rendered to the Lender by the professional for whom reimbursement is sought; provided, however, that such detail shall
in no event be required to reveal confidential communications between the Lender and such professional that are subject to the attorney-client privilege.



Section 11.2 INDEMNIFICATION. THE BORROWER SHALL INDEMNIFY THE LENDER AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS,
EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS FEES) TO WHICH ANY OF
THEM MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN
DOCUMENTS, (C) ANY BREACH BY THE BORROWER OF ANY REPRESENTATION, WARRANTY, COVENANT, OR OTHER AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY HAZARDOUS MATERIAL
LOCATED ON, ABOUT, WITHIN, OR AFFECTING ANY OF THE PROPERTIES OR ASSETS OF THE BORROWER OR ANY SUBSIDIARY, (E) THE USE OR PROPOSED USE OF ANY LETTER OF CREDIT, (F) ANY AND ALL TAXES, LEVIES, DEDUCTIONS, AND CHARGES IMPOSED ON THE LENDER OR ANY OF
THE LENDERS CORRESPONDENTS IN RESPECT OF ANY LETTER OF CREDIT, OR (G) ANY INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, RELATING TO ANY OF THE
FOREGOING. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER THIS SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST
ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS,



LOAN AGREEMENT - Page 38



---

DISBURSEMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEYS FEES) ARISING OUT OF OR RESULTING FROM THE SOLE
CONTRIBUTORY OR ORDINARY NEGLIGENCE OF SUCH PERSON. ANYTHING HEREIN TO THE CONTRARY NOTWITHSTANDING, THE LENDER SHALL NOT BE INDEMNIFIED OR HELD HARMLESS FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.



Section 11.3 Limitation of Liability. Neither the Lender nor any
Affiliate, officer, director, employee, attorney, or agent of the Lender shall have any liability with respect to, and the Borrower hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or
consequential damages suffered or incurred by the Borrower in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other
Loan Documents. The Borrower hereby waives, releases, and agrees not to sue the Lender or any of the Lenders Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with,
arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents.



Section 11.4 No Duty. All attorneys, accountants, appraisers, and other professional Persons and consultants retained
by the Lender shall have the right to act exclusively in the interest of the Lender and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to the Borrower or any of the
Borrowers shareholders or any other Person other than Lender.



Section 11.5 Lender Not Fiduciary. The relationship between the Borrower and the Lender is solely that of debtor and creditor, and the Lender has no fiduciary or other special relationship with the Borrower, and no term or condition
of any of the Loan Documents shall be construed so as to deem the relationship between the Borrower and the Lender to be other than that of debtor and creditor. The Lender shall in good faith hold in confidence all information, memoranda, or
extracts furnished to the Lender by the Borrower hereunder or in connection with the negotiation hereof; provided that the Lender may disclose such information (i) to its Affiliates, accountants or counsel; (ii) to any regulatory agency having the
authority to examine the Lender, as required by any legal or governmental process or otherwise by law, and (iv) to the extent that such information shall be publicly available or shall have been known to the Lender independently of any disclosure by
the Borrower hereunder or in connection herewith.



Section 11.6
Equitable Relief. The Borrower recognizes that in the event the Borrower fails to pay, perform, observe, or discharge any or all of the Obligations, any remedy at law may prove to be inadequate relief to the Lender. The Borrower therefore
agrees that the Lender, if the Lender so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.



Section 11.7 No Waiver; Cumulative Remedies. No failure on the part of the Lender to exercise and no delay in
exercising, and no course of dealing with respect to, any right, power, or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege under this Agreement preclude any
other or further exercise thereof or the exercise of any other right, power, or privilege. The rights and remedies provided for in this Agreement and the other Loan Documents are cumulative and not exclusive of any rights and remedies provided by
law.

Section 11.8 Successors and Assigns. This Agreement is binding upon and shall inure to the benefit
of the Lender and the Borrower and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Lender.



Section 11.9 Survival. All representations and warranties made in this
Agreement or any other Loan Document or in any document, statement, or certificate furnished in connection with this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and no investigation by the
Lender or any closing shall affect the representations and warranties or the right of the Lender to rely upon them. Without prejudice to the survival of any other obligation of the Borrower hereunder, the obligations of the Borrower under
Sections 11.1 and 11.2 shall survive repayment of the Note and termination of the Commitment and the Letters of Credit.



Section 11.10 ENTIRE AGREEMENT; AMENDMENT. THIS AGREEMENT, THE NOTE, AND THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE
AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO. The provisions of this Agreement and the other Loan Documents to which the Borrower is a party may be
amended or waived only by an instrument in writing signed by the parties hereto.



Section 11.11 Notices. Unless otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including by facsimile transmission) and mailed, faxed or
delivered, to the address, facsimile number or subject to the last sentence hereof electronic mail address specified for notices below the signatures hereon or to such other address as shall be designated by such party in a notice to the other
parties. All such other notices and other communications shall be deemed to have been given or made upon the earliest to occur of (i) actual receipt by the intended recipient or (ii) (A) if delivered by hand or courier, (B) if delivered by mail,
four business days after deposit in the mail, postage prepaid; (C) if delivered by facsimile when sent and receipt has been confirmed by telephone; and (D) if delivered by electronic mail (which form of delivery is subject to the provisions of the
last sentence below) when delivered; provided, however, that notices and other communications pursuant to Article II shall not be effective until actually received by the Lender. Electronic mail and intranet websites may be used only to
distribute only routine communications, such as financial statements and other information, and to distribute Loan Documents for execution by the parties thereto, and may not be used for any other purpose.



Section 11.12 Governing Law; Venue; Service of Process. This Agreement
shall be governed by and construed in accordance with the laws of the State of Texas and the applicable laws of the United States of America. This Agreement has been entered into in Dallas County, Texas, and it shall be performable for all purposes
in Dallas County, Texas. Any action or proceeding against the Borrower under or in connection with any of the Loan Documents may be brought in any state or federal court in Dallas County, Texas. The Borrower hereby irrevocably (a) submits to the
nonexclusive jurisdiction of such courts, and (b) waives any objection it may



LOAN AGREEMENT - Page 40



---

now or hereafter have as to the venue of any such action or proceeding brought in any such court or that any such court
is an inconvenient forum. The Borrower agrees that service of process upon it may be made by certified or registered mail, return receipt requested, at its address specified or determined in accordance with the provisions of Section 11.12.
Nothing herein or in any of the other Loan Documents shall affect the right of the Lender to serve process in any other manner permitted by law or shall limit the right of the Lender to bring any action or proceeding against the Borrower or with
respect to any of its property in courts in other jurisdictions. Any action or proceeding by the Borrower against the Lender shall be brought only in a court located in Dallas County, Texas.



Section 11.13 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.



Section 11.14 Severability. Any provision of this Agreement held by a court of competent jurisdiction to be invalid or unenforceable shall not
impair or invalidate the remainder of this Agreement and the effect thereof shall be confined to the provision held to be invalid or illegal.



Section 11.15 Headings. The headings, captions, and arrangements used in this Agreement are for convenience only and shall not affect the
interpretation of this Agreement.



Section 11.16
Intentionally Omitted.



Section 11.17
Construction. The Borrower and the Lender acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement and the other Loan Documents with its legal counsel
and that this Agreement and the other Loan Documents shall be construed as if jointly drafted by the Borrower and the Lender.



Section 11.18 Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is
not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default if such action is taken or such condition exists.



Section 11.19 WAIVER OF JURY TRIAL. TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, BORROWER HEREBY IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE
LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF LENDER IN THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.



Section 11.20 Arbitration.



A. Upon the demand of any party, any dispute under this Agreement or the Loan Documents shall be resolved by binding arbitration (except as set forth in
Section 11.20.E. below) in accordance with the terms of this Agreement or the



LOAN AGREEMENT - Page 41



---

other Loan Documents. Any party may by summary proceedings bring an action in court to compel arbitration
of a Dispute. Any party who fails or refuses to submit to arbitration following a lawful demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any Dispute.



B. Arbitration proceedings shall be administered by the American Arbitration
Association (AAA) or such other administrator as the parties shall mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted to arbitration shall be resolved in accordance with the Federal
Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the foregoing documents. The arbitration shall be conducted at a location in Dallas County, Texas selected by the AAA or other
administrator. If there is any inconsistency between the terms hereof and any such rules, the terms and procedures set forth herein shall control.. All statutes of limitation applicable to any Dispute shall apply to any arbitration proceeding. All
discovery activities shall be expressly limited to matters directly relevant to the Dispute being arbitrated. Judgment upon any award rendered in an arbitration may be entered in any court having jurisdiction; provided however, that nothing
contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under Section 91 of Title 12 of the United States Code or any similar applicable state law.



C. No provision hereof shall limit the right of any party to exercise
self-help remedies such as setoff, foreclosure against or sale of any real or personal property collateral or security, or to obtain provisional or ancillary remedies, including without limitation, injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver from a court of competent jurisdiction before, after or during the pendency of any arbitration or other proceeding. The exercise of any such remedy shall not waive the right of any party to compel
arbitration hereunder.



D. Arbitrators must be active members
of the Texas State Bar with expertise in the substantive law applicable to the subject matter of the Dispute. Arbitrators are empowered to resolve Disputes by summary rulings in response to motions filed prior to the final arbitration hearing.
Arbitrators (i) shall resolve all Disputes in accordance with the substantive law of the State of Texas, (ii) may grant any remedy or relief that a court of the State of Texas could order or grant within the scope hereof and such ancillary relief as
is necessary to make effective any award, and (iii) shall have the power to award recovery of all costs and fees, to impose sanctions and to take such other actions as they deem necessary to the same extent a judge could pursuant to the Federal
Rules of Civil Procedure, the Texas Rules of Civil Procedure or other applicable law. Any Dispute in which the amount in controversy is $5,000,000 or less shall be decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees and expenses). By submission to a single arbitrator, each party expressly waives any right or claim to recover more than $5,000,000. Any Dispute in which the amount in controversy exceeds $5,000,000 shall
be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations.



LOAN AGREEMENT - Page 42



---

E. Notwithstanding anything herein to the contrary, in any arbitration in which the amount in controversy
exceeds $25,000,000, the arbitrators shall be required to make specific, written findings of fact and conclusions of law. In such arbitrations (i) the arbitrators shall not have the power to make any award which is not supported by substantial
evidence or which is based on legal error, (ii) an award shall not be binding upon the parties unless the findings of fact are supported by substantial evidence and the conclusions of law are not erroneous under the substantive law of the State of
Texas, and (iii) the parties shall have in addition to the grounds referred to in the Federal Arbitration Act for vacating, modifying or correcting an award the right to judicial review of (1) whether the findings of fact rendered by the arbitrators
are supported by substantial evidence, and (2) whether the conclusions of law are erroneous under the substantive law of the State of Texas. Judgment confirming an award in such a proceeding may be entered only if a court determines the award is
supported by substantial evidence and not based on legal error under the substantive law of the State of Texas.



F. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding
within 180 days of the filing of the Dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary
course of its business, by applicable law or regulation, or to the extent necessary to exercise any judicial review rights set forth herein. If more than one agreement for arbitration by or between the parties potentially applies to a Dispute, the
arbitration provision most directly related to the foregoing documents or the subject matter of the Dispute shall control. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement. This arbitration provision shall survive termination, amendment or expiration of
any of the foregoing documents or any relationship between the parties.



G. Lender and Borrower hereby agree to keep all Disputes and arbitration proceedings strictly confidential, provided, however, that Lender and Borrower may disclose such confidential information as is necessary in any
litigation between Lender and Borrower or as required by applicable law and, on a confidential basis, to accountants, attorneys and other consultants in the ordinary course of business.



Section 11.21 Additional Interest Provision. It is expressly stipulated and agreed to be the intent of the Borrower
and the Lender at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on the indebtedness evidenced by any Note, any Loan Document, and the Related Indebtedness (or applicable United
States federal law to the extent that it permits the Lender to contract for, charge, take, reserve or receive a greater amount of interest than under Texas law). If the applicable law is ever



LOAN AGREEMENT - Page 43



---

judicially interpreted so as to render usurious any amount (i) contracted for, charged, taken, reserved or received
pursuant to any Note, any of the other Loan Documents or any other communication or writing by or between the Borrower and the Lender related to the transaction or transactions that are the subject matter of the Loan Documents, (ii) contracted for,
charged, taken, reserved or received by reason of the Lenders exercise of the option to accelerate the maturity of any Note and/or any and all indebtedness paid or payable by the Borrower to the Lender pursuant to any Loan Document other than
any Note (such other indebtedness being referred to in this Section as the Related Indebtedness), or (iii) the Borrower will have paid or the Lender will have received by reason of any voluntary prepayment by the Borrower of any
Note and/or the Related Indebtedness, then it is the Borrowers and the Lenders express intent that all amounts charged in excess of the Maximum Lawful Rate shall be automatically canceled, ab initio, and all amounts in excess of
the Maximum Lawful Rate theretofore collected by the Lender shall be credited on the principal balance of any Note and/or the Related Indebtedness (or, if any Note and all Related Indebtedness have been or would thereby be paid in full, refunded to
the Borrower), and the provisions of any Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder reduced, without the necessity of the execution of any new document, so
as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder and thereunder; provided, however, if any Note has been paid in full before the end of the stated term of any such Note, then
the Borrower and the Lender agree that the Lender shall, with reasonable promptness after the Lender discovers or is advised by the Borrower that interest was received in an amount in excess of the Maximum Lawful Rate, either refund such excess
interest to the Borrower and/or credit such excess interest against such Note and/or any Related Indebtedness then owing by the Borrower to the Lender. The Borrower hereby agrees that as a condition precedent to any claim seeking usury penalties
against the Lender, the Borrower will provide written notice to the Lender, advising the Lender in reasonable detail of the nature and amount of the violation, and the Lender shall have sixty (60) days after receipt of such notice in which to
correct such usury violation, if any, by either refunding such excess interest to the Borrower or crediting such excess interest against the Note to which the alleged violation relates and/or the Related Indebtedness then owing by the Borrower to
the Lender. All sums contracted for, charged, taken, reserved or received by the Lender for the use, forbearance or detention of any debt evidenced by any Note and/or the Related Indebtedness shall, to the extent permitted by applicable law, be
amortized or spread, using the actuarial method, throughout the stated term of such Note and/or the Related Indebtedness (including any and all renewal and extension periods) until payment in full so that the rate or amount of interest on account of
any Note and/or the Related Indebtedness does not exceed the Maximum Lawful Rate from time to time in effect and applicable to such Note and/or the Related Indebtedness for so long as debt is outstanding. In no event shall the provisions of Chapter
346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving triparty accounts) apply to this Note and/or any of the Related Indebtedness. Notwithstanding anything to the contrary contained herein or in any of
the other Loan Documents, it is not the intention of the Lender to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.



Section 11.22 Ceiling Election. To the extent that Lender is relying
on Chapter 303 of the Texas Finance Code to determine the Maximum Lawful Rate payable on any such Note and/or any other portion of the Indebtedness, the Lender will utilize the weekly ceiling from time to time in effect as provided in such Chapter
303, as amended. To the extent United States federal law permits the Lender to contract for, charge, take, receive or reserve a greater amount



LOAN AGREEMENT - Page 44



---

of interest than under Texas law, Lender will rely on United States federal law instead of such Chapter 303 for the
purpose of determining the Maximum Lawful Rate. Additionally, to the extent permitted by applicable law now or hereafter in effect, the Lender may, at its option and from time to time, utilize any other method of establishing the Maximum Lawful Rate
under such Chapter 303 or under other applicable law by giving notice, if required, to the Borrower as provided by applicable law now or hereafter in effect.

in San Francisco, California as its prime rate, whether or not the Borrowers have notice thereof, with the understanding that the Prime Rate is one of Wells Fargo Bank, N.A.s base rates and serves as the basis upon which effective rates of
interest are calculated for those loans making reference thereto, and is evidenced by the recording thereof after its announcement in such internal publication or publications as Wells Fargo Bank, N.A. may designate, which change in the Prime Rate
shall be effective on the day the change is announced within Wells Fargo Bank, N.A.

Section 2.1 Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days
elapsed, except with respect to Base Rate Loans, in which case interest shall be computed on the basis of a 365/366-day year, as the case may be, actual days elapsed) at the lesser of (i) either (A) at a fluctuating rate per annum equal to the Base
Rate in effect from time to time, or (B) at a fixed rate per annum determined by Bank to be 2.25%above LIBOR in effect on the first day of the applicable Fixed Rate Term, or (ii) the

Maximum Rate. When interest is determined in relation to the Prime Rate, each change in the rate of interest hereunder
shall become effective on the date each Prime Rate change is announced within Bank. With respect to each LIBOR selection option selected hereunder, Bank is hereby authorized to note the date, principal amount, interest rate and Fixed Rate Term
applicable thereto and any payments made thereon on Banks books and records (either manually or by electronic entry) and/or on, any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the
information noted.



Section 2.2 Selection of Interest Rate
Options. At any time any portion of this Note bears interest determined in relation to LIBOR, it may be continued by Borrower at the end of the Fixed Rate Term applicable thereto so that all or a portion thereof bears interest determined in
relation to the Base Rate or to LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Base Rate, Borrower may convert all or a portion thereof so that it bears
interest determined in relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as Borrower requests an advance hereunder or wishes to select a LIBOR option for all or a portion of the outstanding principal balance hereof, and at
the end of each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the interest rate option selected by Borrower; (ii) the principal amount subject thereto; and (iii) for each LIBOR selection, the length of the applicable Fixed Rate
Term. Any such notice may be given by telephone (or such other electronic method as Bank may permit) so long as, with respect to each LIBOR selection, (A) if requested by Bank, Borrower provides to Bank written confirmation thereof not later than
three (3) Business Days after such notice is given, and (B) such notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate Term, or at a later time during any Business Day if Bank, at its sole option but without obligation to do
so, accepts Borrowers notice and quotes a fixed rate to Borrower. If Borrower does not immediately accept a fixed rate when quoted by Bank, the quoted rate shall expire and any subsequent LIBOR request from Borrower shall be subject to a
redetermination by Bank of the applicable fixed rate. If no specific designation of interest is made at the time any advance is requested hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to have made a Base Rate interest
selection for such advance or the principal amount to which such Fixed Rate Term applied.



Section 2.3 Taxes and Regulatory Costs. Borrower shall pay to Bank immediately upon demand, in addition to any other amounts due or to become due hereunder, any and all (i) withholdings, interest equalization
taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in any manner to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR Reserve
Percentage, assessment rates imposed by the Federal Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign governmental authority or resulting from compliance by Bank with any request or directive (whether
or not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR to the extent they are not included in the calculation of LIBOR. In determining which of the foregoing are attributable to any
LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.



Section 2.4 Payment of Interest. Interest accrued on this Note shall be payable on the Interest Payment Date.

---

Section 2.5 Default Interest. From and after the maturity date of this Note, or such earlier date
as all principal owing hereunder becomes due and payable by acceleration or otherwise, the outstanding principal balance of this Note shall bear interest until paid in full at an increased rate per annum (computed on the basis of a 360-day year,
actual days elapsed, except with respect to Base Rate Loans, in which case interest shall be computed on the basis of a 365/366-day year, as the case may be, actual days elapsed) equal to 4% above the rate of interest from time to time applicable to
this Note, but in no event at a rate greater than the Maximum Rate.

BORROWING AND REPAYMENT:



Section 3.1 Borrowing and
Repayment. Borrower may from time to time during the term of this Note borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of the Loan Agreement
between Borrower and Bank defined below; provided however, that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. Each borrowing, conversion to or continuation of LIBOR Loans shall be in
a principal amount of $500,000 or a whole multiple of $250,000 in excess thereof. The unpaid principal balance of this obligation at any time shall be the total amounts advanced hereunder by the holder hereof less the amount of principal payments
made hereon by or for any Borrower, which balance may be endorsed hereon from time to time by the holder. The outstanding principal balance of this Note and all outstanding accrued interest thereon shall be due and payable in full on the Termination
Date.



Section 3.2 Advances. Advances hereunder,
to the total amount of the principal sum available hereunder, may be made by the holder at the oral or written request of (i) David Kirk, any one acting alone, who are authorized to request advances and direct the disposition of any advances until
written notice of the revocation of such authority is received by the holder at the office designated above, or (ii) any person, with respect to advances deposited to the credit of any deposit account of any Borrower, which advances, when so
deposited, shall be conclusively presumed to have been made to or for the benefit of each Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall
have no obligation to determine whether any person requesting an advance is or has been authorized by any Borrower.



Section 3.3 Application of Payments. Each payment made on this Note shall be credited first, to any interest then due and second, to the
outstanding principal balance hereof. All payments credited to principal shall be applied first, to the outstanding principal balance of this Note which bears interest determined in relation to the Base Rate, if any, and second, to the outstanding
principal balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest Fixed Rate Term first.



Section 3.4 Credit Sweep. Borrowers operating account will be linked to this Note, so upon the last transaction of each Business Day, any
shortfall in the operating account will be funded by a drawdown of a Base Rate Loan. Paydown on this Note is similar in that any positive collected balance in the operating account at the end of each Business Day will reduce any Base Rate Loans as
contemplated by Section 4.1. For amounts greater than the terms outlined above, Borrower will give the Bank one Business Day advance notice of its intent to borrow hereunder as contemplated in Section 2.1.D of the Loan Agreement.

4. PREPAYMENT:



Section 4.1 Base Rate Loan. Positive credit balances in the Borrowers operating account at the end of each Business Day will reduce any Base
Rate Loans. In addition, Borrower may prepay principal (which shall include all accrued interest thereon) upon one Business Days prior notice to Bank, in any amount and without penalty.



Section 4.2 LIBOR Loan. Borrower may prepay principal (which shall
include all accrued interest thereon) on any LIBOR Loan upon three Business Days prior notice to Bank and in the minimum amount of $1,000,000.00, or a whole multiple of $500,000 in excess thereof;provided however, that if the
outstanding principal balance of such portion of this Note is less than said amount, the minimum prepayment amount shall be the entire outstanding principal balance thereof. In consideration of Bank providing this prepayment option to Borrower, or
if any such portion of this Note shall become due and payable at any time prior to the last day of the Fixed Rate Term applicable thereto, Borrower shall pay to Bank immediately upon demand a fee which is the sum of the discounted monthly
differences for each month from the month of prepayment through the month in which such Fixed Rate Term matures, calculated as follows for each such month:



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



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



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



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



5. EVENTS OF DEFAULT:



This Note is
made pursuant to and is subject to the terms and conditions of that certain Loan Agreement between Borrower and Bank dated as of December 31, 2004 (as amended, restated or modified from time to time, the Loan Agreement). Any default in
the payment or performance of any obligation under this Note, or any defined event of default under the Loan Agreement, shall constitute an Event of Default under this Note.

6. MISCELLANEOUS:



Section 6.1 Remedies. Upon the occurrence of any Event of Default, the holder of this Note, at the holders option, may declare all sums of
principal and accrued and unpaid interest outstanding hereunder to be immediately due and payable without presentment, demand, or any notices of any kind, including without limitation notice of nonperformance, notice of protest, protest, notice of
dishonor, notice of intention to accelerate or notice of acceleration, all of which are expressly waived by each Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Each
Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys fees (to include outside counsel fees and all allocated costs of the holders
in-house counsel to the extent permissible), expended or incurred by the holder in connection with the enforcement of the holders rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution
or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the
foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to any Borrower or any other person or entity.



Section 6.2 Obligations Joint and Several. Should more
than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several.



Section 6.3 Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of Texas.



Section 6.4 Savings Clause. It is the intention of the parties to
comply strictly with applicable usury laws.



Accordingly, notwithstanding any
provision to the contrary in this Note, or in any contract, instrument or document evidencing or securing the payment hereof or otherwise relating hereto (each, a Related Document), in no event shall this Note or any Related Document
require the payment or permit the payment, taking, reserving, receiving, collection or charging of any sums constituting interest under applicable laws that exceed the maximum amount permitted by such laws, as the same may be amended or modified
from time to time (the Maximum Rate). If any such excess interest is called for, contracted for, charged, taken, reserved or received in connection with this Note or any Related Document, or in any communication by Bank or any other
person to Borrower or any other person, or in the event that all or part of the principal or interest hereof or thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of
interest contracted for, charged, taken, reserved or received on the amount of principal actually outstanding from time to time under this Note shall exceed the Maximum Rate, then in such event it is agreed that: (i) the provisions of this paragraph
shall govern and control; (ii) neither Borrower nor any other person or entity now or hereafter liable for the payment of this Note or any Related Document shall be obligated to pay the amount of such interest to the extent it is in excess of the
Maximum Rate; (iii) any such excess interest which is or has been received by Bank, notwithstanding this paragraph, shall be credited against the then unpaid principal balance hereof or thereof, or if this Note or any Related Document has been or
would be paid in full by such credit, refunded to



6



---

Borrower; and (iv) the provisions of this Note and each Related Document, and any other communication to Borrower, shall
immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the Maximum Rate. The right to accelerate the maturity of this Note or any Related Document does not include the right to
accelerate, collect or charge unearned interest, but only such interest that has otherwise accrued as of the date of acceleration. Without limiting the foregoing, all calculations of the rate of interest contracted for, charged, taken, reserved or
received in connection with this Note and any Related Document which are made for the purpose of determining whether such rate exceeds the Maximum Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and
spreading during the period of the full term of this Note or such Related Document, including all prior and subsequent renewals and extensions hereof or thereof, all interest at any time contracted for, charged, taken, reserved or received. The
terms of this paragraph shall be deemed to be incorporated into each Related Document.



To the extent that Chapter 303 of the Texas Finance Code is relevant to Bank for the purpose of determining the Maximum Rate, Bank hereby elects to determine the applicable rate ceiling under such Article by the weekly rate ceiling from
time to time in effect, subject to Banks right subsequently to change such method in accordance with applicable law, as the same may be amended or modified from time to time.



Section 6.5 Right of Setoff; Deposit Accounts. Upon and after the occurrence of an Event of Default, (i) Borrower
hereby authorizes Bank, at any time and from time to time, without notice, which is hereby expressly waived by Borrower, and whether or not Bank shall have declared this Note to be due and payable in accordance with the terms hereof, to set off
against, and to appropriate and apply to the payment of, Borrowers obligations and liabilities under this Note (whether matured or unmatured, fixed or contingent, liquidated or unliquidated), any and all amounts owing by Bank to Borrower
(whether payable in U.S. dollars or any other currency, whether matured or unmatured, and in the case of deposits, whether general or special (except trust and escrow accounts), time or demand and however evidenced), and (ii) pending any such
action, to the extent necessary, to hold such amounts as collateral to secure such obligations and liabilities and to return as unpaid for insufficient funds any and all checks and other items drawn against any deposits so held as Bank, in its sole
discretion, may elect. Borrower hereby grants to Bank a security interest in all deposits and accounts maintained with Bank and with any other financial institution to secure the payment of all obligations and liabilities of Borrower to Bank under
this Note.



Section 6.6 Business Purpose. Borrower
represents and warrants that all loans evidenced by this Note are for a business, commercial, investment, agricultural or other similar purpose and not primarily for a personal, family or household use.



Section 6.7 Certain Tri-Party Accounts. Borrower and Bank agree that
Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts) shall not apply to any revolving loan accounts created under this Note or maintained in connection herewith.
