Services to be performed by the subcontractor; and (b) subcontractor’s contact information (including e-mail address). At its option, Wal-Mart may require Contractor to direct its proposed subcontractors to register on Wal-Mart’s
electronic compliance review portal or allow Contractor to enter data into the portal for its subcontractors. If Contractor enters data on behalf of its subcontractors, Contractor will also be required to upload the paper copy into the electronic
portal immediately. Contractor may use only those subcontractors approved through the electronic compliance review portal, except as otherwise provided in this Agreement. Wal-Mart shall have the right to and may withdraw its approval of certain
subcontractors for the performance of Services without limitation. Should that happen, Contractor shall receive written notice from Wal-Mart of such withdrawal, of approval, and shall be required to immediately take all actions necessary to prevent

	17.	LIMITATION OF DAMAGES 

 Wal-Mart shall not be liable to Contractor for indirect, punitive,
exemplary, incidental, consequential, or special damages, including lost profits, lost income, lost revenues, business interruption or lost business arising out of the Agreement or any Scope of Work or the transactions or relationship between the
Parties contemplated under this Agreement or any Scope of Work, even if Wal-Mart has been advised of the possibility of the damages and regardless of any prior course of dealing between the Parties. 

 

	18.	LIENS 

 Contractor may not cause any encumbrance to attach to or upon any Walmart buildings,
common areas, land, or improvements because of any act or omission of Contractor, its subcontractors, agents, employees, or representatives. Failure to discharge or bond/insure over any encumbrance within fifteen (15) business days following
its filing is a material breach of this Agreement. In addition to any right or remedy Wal-Mart may have for the material breach, Wal-Mart may bond or pay the encumbrance for Contractor’s account without
inquiring into the validity of the encumbrance. If Wal-Mart elects to pay the encumbrance, Contractor will reimburse Wal-Mart, upon demand by Wal-Mart, the amount Wal-Mart paid, plus an additional ten percent (10%) administrative fee, plus
interest. Interest will accrue at the lesser of one and five percent (5%) per annum or the maximum amount allowed by law beginning on the day Wal-Mart bonds or pays the encumbrance and continuing until
Contractor reimburses Wal-Mart the entire amount Wal-Mart paid, plus the administrative fee and any interest accrued.

ARTICLE II 
 Loan and
Advances 
 Section 2.1. Revolving Credit Advances. 

(a) Revolving Credit Advances. Subject to the terms and conditions of this Agreement, the Lender agrees to make one or
more Revolving Credit Advances to the Borrower from time to time from the date hereof to, but not including, the Revolving Credit Maturity Date in an aggregate principal amount at any time outstanding up to, but not exceeding, the amount of the
Revolving Credit Commitment; provided that the aggregate amount of all Revolving Credit Advances at any time outstanding shall not exceed the lesser of (x) Revolving Credit Commitment and (y) the Borrowing Base. Subject to the
foregoing limitations, and the other terms and provisions of this Agreement, the Borrower may borrow, repay, and reborrow Revolving Credit Advances hereunder. 

(b) The Revolving Credit Note. The obligation of the Borrower to repay the Revolving Credit Advances and interest
thereon shall be evidenced by the Revolving Credit Note executed by the Borrower, payable to the order of the Lender, in the maximum principal amount of the Revolving Credit Commitment as originally in effect and dated the date hereof. 

(c) Repayment of Revolving Credit Advances. The Borrower shall repay the unpaid principal amount of all Revolving Credit
Advances on the Revolving Credit Maturity Date, unless sooner due by reason of acceleration by the Lender as provided in this Agreement. 

  
 -14- 

 (d) Interest. Interest on each Revolving Credit Advance shall be due and
payable in arrears on each Interest Payment Date applicable thereto, beginning on February 1, 2011, and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and
after judgment, and before and after the commencement of any proceeding under any bankruptcy law. 
 (e) Borrowings,
Conversions and Continuations of Revolving Credit Advances. 
 (i) Each borrowing, each conversion of a Revolving Credit
Advance from one Type to the other, and each continuation of a Eurodollar Rate Loan shall be made upon the Borrower’s irrevocable notice to the Lender, which may be given by telephone. Each such notice must be received by the Lender not later
than 2:00 p.m. (1) three Business Days prior to the requested date of any borrowing of, conversion to or continuation of a Eurodollar Rate Loan or of any conversion of a Eurodollar Rate Loan to a Base Rate Loan, and (2) on the requested
date of any borrowing of a Base Rate Loan. Each such telephonic notice must be confirmed promptly by delivery to the Lender of a written Advance Request Form, appropriately completed and signed by the Borrower. Each Advance Request Form (whether
telephonic or written) shall specify (i) whether the Borrower is requesting a borrowing, a conversion of a Revolving Credit Advance from one Type to the other, or a continuation of a Eurodollar Rate Loan, (ii) the requested date of the
borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (3) the principal amount of the Revolving Credit Advance to be borrowed, converted or continued, (4) the Type of Revolving Credit Advance to be
borrowed or to which an existing Revolving Credit Advance is to be converted, and (5) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type of Revolving Credit Advance in an Advance
Request Form or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Revolving Credit Advance shall be made as, or converted to, a Base Rate Loan. Any such automatic conversion to a Base Rate
Loan shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loan. If the Borrower requests a borrowing of, conversion to, or continuation of a Eurodollar Rate Loan in any such
Advance Request Form, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month. Subject to the terms and conditions of this Agreement, each 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 and maintained with the Lender at the Principal Office. 

  
 -15- 

 (ii) Revolving Credit Advances shall be in a minimum amount of $50,000 (or such
lesser amount that exhausts any remaining availability under the Revolving Credit Commitment). 
 (iii) 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.

 (iv) Upon satisfaction of all applicable conditions, the Lender shall make the proceeds of each Revolving Credit Advance
available to the Borrower in accordance with instructions provided to (and reasonably acceptable to) the Lender by the Borrower. 

(v) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of an
Interest Period for such Eurodollar Rate Loan. During the existence of a default or event of default under this Agreement, no Revolving Credit Advance may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the
Lender. 
 (vi) After giving effect to all borrowings, all conversions of Revolving Credit Advances from one Type to the
other, and all continuations of Revolving Credit Advances as the same Type, there shall not be more than eight Interest Periods in effect for Revolving Credit Advances. 

(f) Reduction or Termination of Revolving Credit Commitment. The Borrower shall have the right to terminate in whole or
reduce in part the unused portion of the Revolving Credit Commitment upon at least three (3) Business Days prior notice (which notice shall be irrevocable) to the Lender specifying the effective date thereof, whether a termination or reduction
is being made, and the amount of any partial reduction, provided that each partial reduction shall be in the amount of $50,000 or an integral multiple thereof (or the entire remaining amount) and the Borrower shall simultaneously prepay the amount
by which the unpaid principal amount of the Revolving Credit Advances exceeds the Revolving Credit Commitment (after giving effect to such notice) plus accrued and unpaid interest on the principal amount so prepaid. The Revolving Credit
Commitment may not be reinstated after it has been terminated or reduced. 
 Section 2.2. Letters of Credit. 

(a) General. Subject to the terms and conditions set forth herein, Borrower may request the Lender, and the Lender
agrees, to issue Letters of Credit for its own account or the account of a Subsidiary in a form reasonably acceptable to the Lender, at 

  
 -16- 

 
any time and from time to time prior to the Revolving Credit Maturity Date (provided that Borrower shall be a co-applicant, and be jointly and severally liable, with respect to each Letter of
Credit issued for the account of a Subsidiary). The Lender shall have no obligation to issue, and Borrower shall not request the issuance of, any Letter of Credit at any time if after giving effect to such issuance, the LC Exposure would exceed the
LC Commitment or the sum of the total Revolving Credit Advances plus the LC Exposure would exceed the Revolving Credit Commitment. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of
any form of letter of credit application or other agreement submitted by Borrower to, or entered into by Borrower with, the Lender relating to any Letter of Credit, the terms and conditions of this Agreement shall control. 

(b) Request for Issuance, Amendment, Renewal, Extension’, Certain Conditions. To request the issuance of a Letter
of Credit or the amendment, renewal or extension of an outstanding Letter of Credit, Borrower shall hand deliver or telecopy an LC Request to the Lender not later than 12:00 p.m., Dallas, Texas time, on the third Business Day preceding the requested
date of issuance, amendment, renewal or extension. 
 (i) A request for an initial issuance of a Letter of Credit shall
specify in form and detail reasonably satisfactory to the Lender: 
 (A) the proposed issuance date of the requested Letter
of Credit (which shall be a Business Day); 
 (B) the face amount thereof; 

(C) the expiry date thereof (which shall not be later than the close of business on the Letter of Credit Expiration Date); 

(D) the name and address of the beneficiary thereof; 

(E) whether the Letter of Credit is to be issued for its own account or for the account of one of its Subsidiaries (provided
that Borrower shall be a co-applicant, and be jointly and severally liable, with respect to each Letter of Credit issued for the account of a Subsidiary); 

(F) the documents to be presented by such beneficiary in connection with any drawing thereunder; 

(G) the full text of any certificate to be presented by such beneficiary in connection with any drawing thereunder; and 

(H) such other matters as the Lender may reasonably require. 

  
 -17- 

 (ii) A request for an amendment, renewal or extension of any outstanding Letter
of Credit shall specify in form and detail reasonably satisfactory to the Lender: 
 (A) the Letter of Credit to be amended,
renewed or extended; 
 (B) the proposed date of amendment, renewal or extension thereof (which shall be a Business Day);

 (C) the nature of the proposed amendment, renewal or extension; and 

(D) such other matters as the Lender may reasonably require. 

If requested by the Lender, Borrower also shall submit a letter of credit application on the Lender’s standard form in connection with any
request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and, upon issuance, amendment, renewal or extension of each Letter of Credit, Borrower shall be deemed to represent and warrant that), after
giving effect to such issuance, amendment, renewal or extension, (i) the LC Exposure shall not exceed the LC Commitment and (ii) the sum of the total Revolving Credit Advances plus the LC Exposure shall not exceed the Revolving Credit
Commitment. Unless the Lender shall agree otherwise, no Letter of Credit shall be in an initial amount less than $100,000. 

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of
(i) the date which is one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the Letter of Credit Expiration Date; provided
that this paragraph (c) shall not prevent Borrower from obtaining Letters of Credit that provide by their terms that they will automatically be extended for one or more successive periods not to exceed one year each (and, in any case, not to
extend beyond the Letter of Credit Expiration Date) unless the Lender elects not to extend for any such additional period by giving notice of such election to the beneficiary at least 30 days prior to the expiry date thereof. 

(d) Reimbursement. If the Lender shall make any LC Disbursement in respect of a Letter of Credit, Borrower shall
reimburse such LC Disbursement by paying to the Lender an amount equal to such LC Disbursement not later than 2:00 p.m., Dallas, Texas time, on the date that such LC Disbursement is made if Borrower shall have received notice of such LC Disbursement
prior to 11:00 a.m., Dallas, Texas time, on such date, or, if such notice has not been received by Borrower prior to such time on such date, then not later than 2:00 p.m., Dallas, Texas time, on the Business Day immediately following the day that
Borrower receives such notice; provided that Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.1 that such payment be financed with Revolving Credit Advances in an equivalent
amount and, to the extent so financed, Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Revolving Credit Advances. 

  
 -18- 

 (e) Obligations Absolute. The Reimbursement Obligation of Borrower as
provided in Section 2.2(d) shall be absolute, unconditional and irrevocable, and shall be paid and performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any
lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein; (ii) any draft or other document presented under a Letter of Credit being proved to be forged, fraudulent, invalid or insufficient
in any respect or any statement therein being untrue or inaccurate in any respect; (iii) payment by the Lender under a Letter of Credit against presentation of a draft or other document that fails to comply with the terms of such Letter of
Credit; (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.2, constitute a legal or equitable discharge of or provide a right of
setoff against, the obligations of Borrower hereunder; (v) the fact that a Default shall have occurred and be continuing; (iv) any material adverse change in the condition (financial or otherwise), results of operations, assets,
liabilities (contingent or otherwise), material agreements, properties, solvency, business, management, prospects or value of the Borrower; or (vii) any other fact, circumstance or event whatsoever. The Lender shall not have any liability or
responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any
error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond the control of the Lender; provided that the foregoing shall not be construed to excuse the Lender from liability to Borrower to the extent of any direct damages (as
opposed to consequential, special, punitive or other indirect damages, claims in respect of which are hereby waived by Borrower to the extent permitted by applicable law) suffered by Borrower that are caused by the Lender’s (i) failure to
exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof or (ii) gross negligence or willful misconduct as finally determined in a judgment of a court of competent
jurisdiction. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Lender (as finally determined by a court of competent jurisdiction), the Lender shall be deemed to have exercised care
in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a
Letter of Credit, the Lender may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make
payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 
 (f)
Disbursement Procedures. The Lender shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Lender shall promptly give written notice to the Borrower of
such demand for payment and whether the Lender has made or will make an LC 

  
 -19- 

 
Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve Borrower of its Reimbursement Obligation to the Lender with respect to any such LC
Disbursement (other than with respect to the timing of such Reimbursement Obligation set forth in Section 2.2(d)). 

(g) Letter of Credit Fees and Fronting Fees. The Borrower shall pay to the Lender a Letter of Credit fee (the
“Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Margin for Eurodollar Rate Loans times the daily amount available to be drawn under such Letter of Credit. In addition to the Letter of Credit Fee, the
Borrower shall pay the Lender a fronting fee (the “Fronting Fee”) equal to 0.25% per annum of the amount available to be drawn under any outstanding Letter of Credit. Letter of Credit Fees and Fronting Fees shall be
(i) due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand
and (ii) computed on a quarterly basis in arrears. 
 (h) Interim Interest. If the Lender shall make any LC
Disbursement, then, unless Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest payable on demand, for each day from and including the date such LC Disbursement
is made to but excluding the date that Borrower reimburses such LC Disbursement, at the Default Rate. 
 (i) Other.
The Lender shall be under no obligation to issue any Letter of Credit if: 
 (i) any order of any Governmental Authority or
arbitrator shall by its terms purport to enjoin or restrain the Lender from issuing such Letter of Credit, or any legal requirement applicable to the Lender or any request or directive (whether or not having the force of law) from any Governmental
Authority with jurisdiction over the Lender shall prohibit, or request that the Lender refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the Lender with respect to such Letter of
Credit any restriction, reserve or capital requirement (for which the Lender is not otherwise compensated hereunder) not in effect on the date hereof, or shall impose upon the Lender any unreimbursed loss, cost or expense which was not applicable on
the date hereof and which the Lender deems material to it; or 
 (ii) the issuance of such Letter of Credit would violate one
or more policies of general application of the Lender. 
 (j) The Lender shall be under no obligation to amend any Letter of
Credit if (A) the Lender would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter
of Credit. 

  
 -20- 

 Section 2.3. Use of Proceeds. The proceeds of the Revolving Credit Advances shall be
used by the Borrower for working capital purposes, Capital Expenditures and general corporate purposes of the Borrower and its Affiliates in the ordinary course of business. 

Section 2.4. Evidence of Debt. The Revolving Credit Advances made by the Lender shall be evidenced by one or more accounts or
records maintained by the Lender in the ordinary course of business. The accounts or records maintained by the Lender shall be presumed to be correct absent manifest error of the amount of the Revolving Credit Advances made by the Lender to the
Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. 

Section 2.5. General Provisions Regarding Interest; Etc. 

(a) Notification of Rate. The Lender shall notify the Borrower of any change in the Lender’s Base Rate used in
determining the Applicable Rate promptly following the public announcement of such change. 
 (b) Applicable Rate.
Subject to the provisions of subsection (c) below, each Advance shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the lesser of (A) the Maximum Lawful
Rate and (B) the Applicable Rate. 
 (c) Default Rate. If any amount payable by the Borrower under any Loan
Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter, upon the giving of prior written notice by Lender to Borrower, bear interest at a
fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable laws. Furthermore, while any default or event of default exists, the Borrower shall pay interest on the principal amount of all
outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable laws. Accrued and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand. 
 (d) Maximum Lawful Rate Limitations. If at any time the rate of
interest applicable to any portion of the Loans would 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 Loans below
the Maximum Lawful Rate until the aggregate amount of interest accrued on the Loans equals the aggregate amount of interest which would have accrued on the Loans if the interest rate had not been limited by the Maximum Lawful Rate. 

(e) Computations of Rate. All computations of fees and interest shall be made on the basis of a 360-day year and actual
days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year), unless such computation would cause the fees and interest to exceed the Maximum

  
 -21- 

 
Lawful Rate, in which event, such computation shall be on the basis of a 365 or 366 day year, as applicable. Interest shall accrue on each Loan for the day on which the Loan is made, or any
portion thereof, but not for the day on which the Loan or such portion is paid. 
 (f) Capital Adequacy. If after the
date hereof, the Lender shall have determined that any central bank or other Governmental Authority properly authorized to do so has adopted or implemented (and has taken all necessary action to legally adopt or implement) any applicable law, rule,
or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof, compliance with which by the Lender would have the effect of reducing the rate of return on the Lender’s capital as
a consequence of its obligations hereunder or the transactions contemplated hereby to a level below that which the Lender could have achieved but for such adoption, implementation, change, or compliance (taking into consideration the Lender’s
policies with respect to capital adequacy) by an amount deemed by the Lender to be material, then from time to time, within ten (10) Business Days after demand by the Lender, the Borrower shall pay to the Lender (or its parent) such additional
amount or amounts as will compensate the Lender for such reduction. The Lender will give the Borrower notice of any event occurring after the date of this Agreement which will entitle the Lender to compensation pursuant to this Section promptly
after it obtains knowledge thereof and determines to request such compensation, and no claim by the Lender for compensation under this Section shall in any case be made until such time as the Lender determines that it is legally required to comply
with such law, rule, regulations or change thereto giving rise to such claim. A certificate of the Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive,
provided that the determination thereof is made on a reasonable basis, In determining such amount or amounts, the Lender may use any reasonable averaging and attribution methods. 

(g) Illegality. If the Lender determines that any law has made it unlawful, or that any Governmental Authority has
asserted that it is unlawful, for the Lender or its Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, and Lender also makes such determination with respect to
substantially all other similar credit facilities with other borrowers, then, on notice thereof by the Lender to the Borrower, any obligation of the Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate
Loans shall be suspended until the Lender notifies the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from the Lender, prepay or, if applicable, convert
all Eurodollar Rate Loans to Base Rate Loans, either on the last day of the Interest Period therefor, if the Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if the Lender may not lawfully continue to
maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. 

  
 -22- 

 (h) Inability to Determine Eurodollar Rate. If the Lender determines that
for any reason adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or that the Eurodollar Rate for any requested Interest Period with
respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Lender of funding such Eurodollar Rate Loan, and Lender also makes such determination with respect to substantially all other similar credit facilities
with other borrowers, the Lender will promptly so notify the Borrower. Thereafter, the obligation of the Lender to make or maintain Eurodollar Rate Loans shall be suspended until the Lender revokes such notice. Upon receipt of such notice, the
Borrower may revoke any pending request for a borrowing of, conversion to or continuation of a Eurodollar Rate Loan or, failing that, will be deemed to have converted such request into a request for a borrowing of a Base Rate Loan in the amount
specified therein. 
 (i) Increased Costs. 

(i) Increased Costs Generally. If any Change in Law shall: 

(A) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement
against assets of, deposits with or for the account of, or credit extended or participated in by, the Lender (except any reserve requirement contemplated by this Article II); or 

(B) impose on the Lender or the London interbank market any other condition, cost or expense affecting this Agreement or
Eurodollar Rate Loans made by the Lender; 
 and the result of any of the foregoing shall be to increase the cost to the
Lender of making or maintaining any Eurodollar Rate Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to the Lender, or to reduce the amount of any sum received or receivable by the Lender (whether of principal,
interest or any other amount) then, upon request of the Lender, the Borrower will pay to the Lender such additional amount or amounts as will compensate the Lender for such additional costs incurred or reduction suffered, but only to the extent
Lender is assessing and collecting such additional amounts from other borrowers under substantially all other similar credit facilities and also only to the extent any such Change in Law is generally applicable to similarly situated lenders. 

(ii) Capital Requirements. If the Lender determines that any Change in Law affecting the Lender or any lending office of
the Lender or the Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on the Lender’s capital or on the capital of the Lender’s holding company, if any, as a
consequence of this Agreement, the commitments of the Lender or the Loans made by the Lender to a level below that which the Lender or the Lender’s holding company could have achieved but for 

  
 -23- 

 
such Change in Law (taking into consideration the Lender’s policies and the policies of the Lender’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to the Lender such additional amount or amounts as will compensate the Lender or the Lender’s holding company for any such reduction suffered; provided, however, that any such Change in Law is generally applicable to similarly
situated lenders and only to the extent Lender is assessing and collecting such additional amounts from other borrowers under substantially all other similar credit facilities. 

(iii) Certificates for Reimbursement. A certificate of the Lender setting forth, in detail, with explanations for the
additional amounts, the amount or amounts necessary to compensate the Lender or its holding company, as the case may be, as specified in this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay the
Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 (iv) Delay in
Requests. Failure or delay on the part of the Lender to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of the Lender’s right to demand such compensation, provided that the
Borrower shall not be required to compensate the Lender pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender notifies the Borrower of
the Change in Law giving rise to such increased costs or reductions and of the Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the
nine-month period referred to above shall be extended to include the period of retroactive effect thereof). 
 (v)
Reserves on Eurodollar Rate Loans. The Borrower shall pay to the Lender, as long as the Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently
known as “Eurocurrency liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by the Lender in good
faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Loan, provided the Borrower shall have received at least 10 days’ prior notice of such additional interest
from the Lender. If the Lender fails to give notice 10 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 10 days from receipt of such notice. 

  
 -24- 

 (j) Funding Losses. Upon demand of the Lender from time to time, the
Borrower shall promptly compensate the Lender for and hold the Lender harmless from any loss, cost or expense incurred by it as a result of:

Borrower shall be obligated to pay the excess amount of such interest or any other excess sum paid for the use, forbearance, or detention of sums loaned pursuant hereto. In the event the Lender ever receives, collects, or applies as interest any
such sum, such amount which would be in excess of the Maximum Lawful Rate shall be applied as a payment and reduction of the principal of the indebtedness evidenced by the Notes, as determined by the Lender; and, if the principal of the Notes have
been paid in full, any remaining excess shall forthwith be paid to the Borrower. In determining whether or not the interest paid or payable exceeds the Maximum Lawful Rate, the Borrower and the Lender shall, to the extent permitted by applicable
law, (a) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal
parts the total amount of interest throughout the entire contemplated term of the indebtedness evidenced by the Notes so that interest for the entire term does not exceed the Maximum Lawful Rate. 

Section 11.21. Confidentiality. The Lender agrees to keep confidential all non-public information provided to it by or on behalf
of the Borrower or any of the Subsidiaries pursuant to this Agreement or any other Loan Document; provided that nothing herein shall prevent any Lender from disclosing any such information (i) to any assignee or participant or prospective

  
 -48- 

 
transferee, if such transferee has agreed in writing to be bound by this Section 11.21, (ii) to its employees, directors, agents, attorneys, accountants and other professional
advisors, (iii) as may be required or appropriate in any report, statement or testimony submitted to any Governmental Authority having or claiming jurisdiction over the Lender (including the Board and the Federal Deposit Insurance Corporation
or any similar organization, whether in the United States or elsewhere, and their respective successors), (iv) as may be required or appropriate in response to any summons or subpoena or in connection with any litigation, (v) in response
to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any requirement of law, (vi) which has been publicly disclosed other than in breach of this Agreement, or (vii) in connection with the
exercise of any remedy hereunder. Subject to the proviso set forth in the immediately preceding sentence, the Lender agrees that such non-public information shall be used and disclosed only in connection with the Lender’s administration of the
Advances under this Agreement and will not be furnished or otherwise made available to other departments or operations of the Lender, including without limitation those departments and operations with responsibilities (including contracting) for
security and related services of the type provided by the Borrower and its Subsidiaries. 
 Section 11.22. USA PATRIOT ACT
NOTIFICATION. The following notification is provided to the Borrower and its Subsidiaries pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318. 

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering
activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each Person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of
credit, or other financial services product. What this means for the Borrower and its Subsidiaries: When the Borrower or any Subsidiary opens an account, if the Borrower or such Subsidiary is an individual, the Lender will ask for the
Borrower’s or such Subsidiary’s name, taxpayer identification number, residential address, date of birth, and other information that will allow the Lender to identify the Borrower or such Subsidiary, and if the Borrower or such Subsidiary
is not an individual, the Lender will ask for the Borrower’s or such Subsidiary’s name, taxpayer identification number, business address and other information that will allow the Lender to identify such Borrower or such Subsidiary. The
Lender may also ask, if the Borrower or such Subsidiary is an individual, to see the Borrower’s or such Subsidiary’s driver’s license or other identifying documents, and if the Borrower or such Subsidiary is not an individual, to see
the Borrower’s or such Subsidiary’s legal organizational documents or other identifying documents.
