	 Title:
	 	 Authorized SignerDescription of Excess Retirement Benefit Arrangements with Executive Officers

 EXHIBIT 10.1 
 DESCRIPTION OF EXCESS RETIREMENT BENEFIT ARRANGEMENTS WITH CERTAIN EXECUTIVE OFFICERS 
 The Company has certain arrangements with some of its
highly compensated employees to compensate them for reductions in retirement benefits resulting in their inability to fully participate in the Company’s U.S. tax-qualified defined benefit pension plan (the “Retirement Plan”).

 The Internal Revenue Code (“Code”) places a limitation on the amount of employee compensation that can be taken into consideration when
calculating employee contributions or benefits under the Retirement Plan. Under the excess retirement benefit arrangement, the Company calculates additional benefits that would have been received by the employees if the compensation in excess of the
Code limit (the “Excess Compensation”) had been included. The retirement benefits based upon the Excess Compensation are determined in a manner consistent with the actuarial determination of normal benefits under the Retirement Plan.

 The annual Excess Compensation benefit amount is reduced by discounting the benefit to present value based upon a discount rate and life expectancy
assumptions consistent with the Retirement Plan. The benefit is further reduced by the amount of additional contributions that the employee would have made. The sum of each year’s excess retirement benefit is paid out in a lump sum cash payment
upon termination of employment. 
 Currently, this arrangement is offered to ten employees, including the Company’s principal executive officer, David
S. Haffner, the Company’s principal financial officer, Matthew C. Flanigan, and the following named executive officers: Jack D. Crusa, Karl G. Glassman and Felix E. Wright. The aggregate amounts awarded to the above executive officers under the
arrangement through year-end 2005 were as follows: Haffner - $49,443; Flanigan - $736; Crusa - $2,662; Glassman - $10,477; and Wright - $229,889. 
 In
conjunction with the Company’s Retirement Plan freeze, no further benefits will accrue under this excess retirement benefit arrangement after December 31, 2006.AMENDED LOAN AGREEMNT

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

 LOAN AGREEMENT - Page 16 

 (3) Interest. The unpaid principal amount of the Term Note shall, subject to the following
sentence, bear interest as provided in the Term Note. If at any time the rate of interest specified in the Term Note shall exceed the Maximum Lawful Rate but for the provisions thereof limiting interest to the Maximum Lawful Rate, then any
subsequent reduction shall not reduce the rate of interest on the Term Note Advances below the Maximum Lawful Rate until the aggregate amount of interest accrued on the Term Note Advances equals the aggregate amount of interest which would have
accrued on the Term Note Advances if the interest rate had not been limited by the Maximum Lawful Rate. Accrued and unpaid interest on the Term Note Advances shall be payable as provided in the Term Note and on the Term Loan Termination Date.

 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 Revolving Credit 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. The
unused facility fee shall be payable quarterly in arrears and on the Revolving Credit Termination Date. 
  

 LOAN AGREEMENT - Page 17 

 Section 2.4 Use of Proceeds. The proceeds of the Revolving Credit Advances shall be used by
the Borrower (i) to pay fees and expenses in connection with the transactions contemplated herein, (ii) to make Permitted Acquisitions, and (iii) 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) One Million Dollars ($1,000,000), (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 Revolving Credit 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 18 

 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 
  

 LOAN AGREEMENT - Page 19 

 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 a Revolving Credit Advance, or (ii) if, as of the Revolving Credit 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 and twenty-five one hundredths 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.

funds, without setoff, 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

of the Obligations shall be applied by the Lender in such order as it elects in its sole discretion. Whenever any payment under this Agreement or any other Loan Document shall be stated to be due on a day that is not a Business Day, such payment

Loans for a period of 90 days from the date of the prepayment. If the Borrower makes any prepayment of a LIBOR Loan before the end of the related interest period, or fails to borrow, convert or extend a LIBOR Loan after giving notice thereof,
or if a LIBOR Loan is converted to a Prime Rate Loan as a result of certain changes in circumstances, the Borrower will reimburse the Lender for any related funding losses and loss of anticipated earnings. 
 3. Term Loans. The Borrower may prepay all or any portion of any Term Loan, and such prepayment shall be applied in inverse order of maturity.

 2. Term Loans. The Borrower must prepay the Term Loan in amounts equal to (i) 100% of the net proceeds from each sale of
assets by the Borrower or any of its Subsidiaries to the extent that the aggregate net proceeds of such sales exceed $100,000 in any fiscal year, and (ii) 100% of the net proceeds from each issuance by the Borrower or any of its Subsidiaries of
Debt or Equity Interests apart from those issued to other Subsidiaries or the Borrower to evidence intercompany transactions among the Borrower and/or any new Subsidiaries. Such payments shall be applied in inverse order of maturity. 
  

 LOAN AGREEMENT - Page 21 

 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. 
 ARTICLE IV 
 Security 
 Section 4.1 Collateral. To secure full and complete payment and performance of the Obligations, the Borrower
shall execute and deliver or cause to be executed and delivered all of the Security Documents required by the Lender covering the Property and collateral described in such Security Documents (which, together with any other Property and collateral
described in the Security Agreement, and any other property which may now or hereafter secure the Obligations or any part thereof, is sometimes herein called the “Collateral”). The Borrower shall execute and cause to be executed
such further documents and instruments, including without limitation, Uniform Commercial Code financing statements, as the Lender, in its sole discretion, deems necessary or desirable to create, evidence, preserve, and perfect its liens and security

any Plan, or the institution by the PBGC of any such proceedings; or (v) complete or partial withdrawal under Section 4201 or 4204 of ERISA from a Multiemployer Plan or the reorganization, insolvency, or termination of any Multiemployer
Plan; and in each case above, such event or condition, together with all other events or conditions, if any, have subjected or could in the reasonable opinion of the Lender subject the Borrower to any tax, penalty, or other liability to a Plan, a
Multiemployer Plan, the PBGC, or otherwise (or any combination thereof) which in the aggregate exceed or could reasonably be expected to exceed One Hundred Thousand Dollars ($100,000). 
 I. The Guarantor or any other Obligated Party shall have died or have been declared incompetent by a court of proper jurisdiction; or if the Guarantor or
any other Obligated Party is a corporation, partnership or other entity, such Person shall be the subject of a bankruptcy or receivership proceeding or shall have dissolved, liquidated or otherwise ceased doing business. 
 J. The Borrower, any of its Subsidiaries, or any Obligated Party, or any of their properties, revenues, or assets, shall become subject to an order of
forfeiture, seizure, or divestiture (whether under RICO or otherwise) and the same shall not have been discharged within thirty (30) days from the date of entry thereof. 
 K. An involuntary proceeding shall be commenced against the Borrower, any Subsidiary, or any Obligated Party seeking liquidation, reorganization, or other
relief with respect to it or its debts under any bankruptcy, insolvency, or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian, or other similar official for it or a substantial part
of its property, and such involuntary proceeding shall remain undismissed and unstayed for a period of thirty (30) days. 
 L. The
Borrower, any Subsidiary or any Obligated Party shall fail to discharge within a period of thirty (30) days after the commencement thereof any attachment, sequestration, or similar proceeding or proceedings involving an aggregate amount in

 LOAN AGREEMENT - Page 40 

 M. A final judgment or judgments for the payment of money in excess of One Hundred Thousand Dollars
($100,000) in the aggregate shall be rendered by a court or courts against the Borrower, any of its Subsidiaries, or any Obligated Party and the same shall not be discharged (or provision shall not be made for such discharge), or a stay of execution
thereof shall not be procured, within thirty (30) days from the date of entry thereof and the Borrower or the relevant Subsidiary or Obligated Party shall not, within said period of thirty (30) days, or such longer period during which
execution of the same shall have been stayed, appeal therefrom and cause the execution thereof to be stayed during such appeal. 
 N. A Change
in Control shall occur. 
 O. A material adverse change in the business, condition (financial or otherwise), operations, prospects, or
Properties of the Borrower or any Subsidiary shall have occurred. 
 Section 10.2 Remedies Upon Default. If any Event of Default
shall occur and be continuing, the Lender may without notice terminate the Commitment and declare the Obligations or any part thereof to be immediately due and payable, and the same shall thereupon become immediately due and payable, without notice,
demand, presentment, notice of dishonor, notice of acceleration, notice of intent to accelerate, notice of intent to demand, protest, or other formalities of any kind, all of which are hereby expressly waived by the Borrower; provided, however, that
upon the occurrence of an Event of Default under Section 10.1.E or Section 10.1.K, the Commitment shall automatically terminate, and the Obligations shall become immediately due and payable without notice, demand,
presentment, notice of dishonor, notice of acceleration, notice of intent to accelerate, notice of intent to demand, protest, or other formalities of any kind, all of which are hereby expressly waived by the Borrower. If any Event of Default shall
occur and be continuing, the Lender may exercise all rights and remedies available to it in law or in equity, under the Loan Documents, or otherwise. 
 Section 10.3 Performance by the Lender. If the Borrower shall fail to perform any covenant or agreement contained in any of the Loan Documents, the Lender may perform or attempt to perform such covenant or
agreement on behalf of the Borrower. In such event, the Borrower shall, at the request of the Lender, promptly pay any amount expended by the Lender in connection with such performance or attempted performance to the Lender, together with interest
thereon at the Default Rate from and including the date of such expenditure to but excluding the date such expenditure is paid in full. Notwithstanding the foregoing, it is expressly agreed that the Lender shall not have any liability or
responsibility for the performance of any obligation of the Borrower under this Agreement or any other Loan Document. 
 Section 10.4
Cash Collateral. If any Event of Default shall occur and be continuing on the Termination Date or if any obligations are outstanding as of the Termination Date, including obligations related to Swap Contracts, the Borrower shall, if requested
by the Lender, immediately deposit with and pledge to the Lender cash or cash equivalent investments in an amount equal to the outstanding Letter of Credit Liabilities, any obligations under any Swap Contracts, and any other obligations due to
Lender, as security for the Obligations.

(including the Lender’s internal charges) incurred in connection with evaluating, 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,

 LOAN AGREEMENT - Page 42 

 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, 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 (iii) 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. 
  

 LOAN AGREEMENT - Page 43 

 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 
  

 LOAN AGREEMENT - Page 44 

 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 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. 
  

 LOAN AGREEMENT - Page 45 

 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
Participations; Etc. The Lender shall have the right at any time and from time to time to grant participations in, and sell and transfer, the Obligations and any Loan Documents. Each actual or proposed participant or assignee, as the case may
be, shall be entitled to receive all information received by the Lender regarding the Borrower and its Subsidiaries, including, without limitation, information required to be disclosed to a participant or assignee pursuant to Banking Circular 181
(Rev., August 2, 1984), issued by the Comptroller of the Currency (whether the actual or proposed participant or assignee is subject to the circular or not). 
 Section 11.21 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 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, 
  

 LOAN AGREEMENT - Page 46 

 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. 
 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 
  

 LOAN AGREEMENT - Page 47 

 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 11.22 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 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 
  

 LOAN AGREEMENT - Page 48 

 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 11.23 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 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.
