 SECTION 2.03. Requests for Revolving Borrowings. To request a Revolving Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m.,
New York City time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of the proposed Borrowing; provided
that any such notice of an ABR Revolving Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.06(e) may be given not later than 10:00 a.m., New York City time, on the date of the proposed Borrowing. Each
such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Borrower.
Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02: 
  
 (i) the aggregate amount of the requested Borrowing; 
  
 (ii) the date of such Borrowing, which shall be a Business Day; 
  
 (iii) whether such Borrowing is to be an ABR Borrowing or a
Eurodollar Borrowing; 
  
 (iv) in the case of a
Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and 
  
 (v) the location and number of the Borrower’s account to which funds are to be disbursed, which shall
comply with the requirements of Section 2.07. 
  
 If no election as to the
Type of Revolving Borrowing is specified, then the requested Revolving Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Revolving Borrowing, then the Borrower shall be deemed to have
selected an Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Revolving Lender of the details thereof and of the amount of such
Revolving Lender’s Revolving Loan to be made as part of the requested Borrowing. 
  

 27 

 SECTION 2.04. Increase in Aggregate Revolving Loan Commitments. 
  
 (a) Request for Increase. The Borrower may, at any time and from time
to time, request, by notice to the Administrative Agent, the Administrative Agent’s approval of an increase of the Aggregate Revolving Loan Commitments (a “Revolving Commitment Increase”) within the limitations hereafter
described, which request shall set forth the amount of each such requested Revolving Commitment Increase. Administrative Agent shall notify all Revolving Lenders of any such request and provide them the first right to participate in the same
proportions that their respective Applicable Revolving Loan Percentages bear to those of all Revolving Lenders who elect to participate therein. Within twenty (20) days of such request, the Administrative Agent shall advise the Borrower of its
approval or disapproval of such request; failure to so advise the Borrower shall constitute disapproval. If the Administrative Agent approves any such Revolving Commitment Increase, then the Aggregate Revolving Commitment may be so increased (up to
the amount of such approved Revolving Commitment Increase) by having one or more of the Revolving Lenders increase the amount of their then existing Revolving Loan Commitments and, if existing Revolving Lenders do not choose to participate to the
extent necessary for the applicable Revolving Commitment Increase to be provided entirely by existing Revolving Lenders, by having one or more new Revolving Lenders become Lenders party to this Agreement. Any Revolving Commitment Increase shall be
subject to the following limitations and conditions: (i) any Revolving Commitment Increase shall not be less than $5,000,000.00 (and shall be in integral multiples of $5,000,000.00 if in excess thereof); (ii) no Revolving Commitment Increase shall
increase the Aggregate Revolving Loan Commitments to an amount in excess of the lesser of (a) $40,000,000.00 plus the amounts by which the principal balance of the Term Loan has been decreased in the aggregate after the Closing Date and (b)
$55,000,000.00; (iii) the provisions of Section 9.04(b) shall apply in respect of any Increasing Lender that is not a Revolving Lender prior to the Revolving Commitment Increase, as if such Increasing Lender were an assignee of a Revolving
Loan Commitment, (iv) the Borrower shall have executed and delivered to the Administrative Agent such Note or Notes as the applicable Increasing Lender shall request to reflect such Revolving Commitment Increase (or, in the case of a new Revolving
Lender, such Revolving Lender’s Revolving Commitment); (v) the Borrower shall have delivered to the Administrative Agent opinions of counsel (substantially similar to the forms of opinions provided for in Section 4.01 modified to apply
to the Revolving Commitment Increase and each Note executed and delivered in connection therewith); (vi) the Guarantors shall have consented in writing to the Revolving Commitment Increase and shall have agreed in writing that their Subsidiary
Guaranties continue in full force and effect; and (vii) the Borrower, Subsidiaries and each Lender shall have executed and delivered such other instruments and documents as the Administrative Agent shall have reasonably requested in connection with
such Revolving Commitment Increase. The form and substance of the documents required under clauses (iv) through (vii) above shall be fully acceptable to the Administrative Agent. The Administrative Agent shall provide written notice to all of the
Lenders hereunder of any Revolving Commitment Increase. 
  
 (b)
Revolving Loans by Increasing Lenders. Upon the effective date of any increase in the Aggregate Revolving Loan Commitments pursuant to the provisions hereof, which effective date shall be mutually agreed upon by the Borrower, each Increasing
Lender and the Administrative Agent, each Increasing Lender shall make a payment to the Administrative Agent in an amount sufficient, upon the application of such payments by all Increasing Lenders to the reduction of the outstanding Revolving Loans
held by the Revolving Lenders, to cause the principal amount outstanding under the Revolving Loans made by each Revolving Lender (including, as applicable, any Increasing Lender) to be in the amount of its Applicable Revolving Loan Percentage (upon
the effective date of such increase). The Borrower hereby irrevocably authorizes each Increasing Lender to fund to the Administrative Agent the payment required to be made pursuant to the immediately preceding sentence for application to the
reduction of the outstanding Revolving Loans held by the 

  

 28 

 
other Revolving Lenders hereunder. If, as a result of the repayment of the Revolving Loans provided for in this Section 2.04(b), any payment of a
Eurodollar Revolving Borrowing occurs on a day which is not the last day of the applicable Interest Period, the Borrower will pay to the Administrative Agent for the benefit of any of the Revolving Lenders holding a Eurodollar Revolving Borrowing
any loss or cost incurred by such Revolving Lender resulting therefrom in accordance with Section 2.16. Upon the effective date of such increase in the Aggregate Revolving Loan Commitments, all Revolving Loans outstanding hereunder (including
any Revolving Loans made by the Increasing Lenders on such date) shall be ABR Loans, subject to the Borrower’s right to convert the same to Eurodollar Loans on or after such date in accordance with the provisions of Section 2.08.

  
 (c) Increasing Lenders’ Participation in Facility
LCs. Upon the effective date of any increase in the Aggregate Revolving Loan Commitments and the making of the Revolving Loans by the Increasing Lenders in accordance with the provisions of Section 2.04(b), each Increasing Lender shall
also be deemed to have irrevocably and unconditionally purchased and received, without recourse or warranty, from the Revolving Lenders party to this Agreement immediately prior to the effective date of such increase, an undivided interest and
participation in any Facility LCs then outstanding, ratably, such that each Revolving Lender (including each Increasing Lender) holds a participation interest in each such Facility LC in proportion equal to its Applicable Revolving Loan Percentage
upon the effective date of such increase in the Aggregate Revolving Loan Commitments. 
  
 (d) No Obligation to Increase Revolving Loan Commitment. Nothing contained herein shall constitute, or otherwise be deemed to be, a commitment or agreement on the part of the Borrower or the Administrative
Agent to give or grant any Revolving Lender the right to increase its Revolving Loan Commitment hereunder at any time or a commitment or agreement on the part of any Revolving Lender to increase its Revolving Loan Commitment hereunder at any time,
and no Revolving Loan Commitment of a Revolving Lender shall be increased without its prior written approval, which it may grant or deny in its sole discretion. 
  

SECTION 2.05. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to
the Borrower from time to time during the Availability Period, in an aggregate principal amount at any time outstanding not to exceed $5,000,000.00; provided that, after giving effect to any Swingline Loan, the sum of the total Revolving
Credit Exposures shall not exceed the least of (i) the Aggregate Revolving Loan Commitments, (ii) the Borrowing Base and (iii) as long as any Obligations under the Term Loan remain unpaid, the TTM EBITDA Threshold; provided further that the
Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline
Loans. 
  
 (b) To request a Swingline Loan, the Borrower shall
notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 12:00 noon, New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date
(which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan
available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section
2.06(e), by remittance to the Issuing Bank) by 3:00 p.m., Tulsa, Oklahoma time, on the requested date of such Swingline Loan. 
  

 29 

 (c) The Swingline Lender may by written notice given to the Administrative Agent not later than 10:00
a.m., New York City time, on any Business Day require the Revolving Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in
which Revolving Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Revolving Lender, specifying in such notice such Revolving Lender’s Applicable Revolving Loan Percentage
of such Swingline Loan or Loans. Each Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Revolving Lender’s
Applicable Revolving Loan Percentage of such Swingline Loan or Loans. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall
not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Revolving Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever. Each Revolving Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.07 with respect to Revolving Loans made by such
Revolving Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from
the Revolving Lenders. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative
Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of
participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Revolving Lenders that shall have made their payments
pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such
payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof. 
  
 SECTION 2.06. Letters of Credit. (a) General. Subject to the
terms and conditions set forth herein, the Borrower may request the issuance of Facility LCs for its own account, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the
Availability Period. 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 the Borrower to, or entered into by
the Borrower with, the Issuing Bank relating to any Facility LC, the terms and conditions of this Agreement shall control. 
  
 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Facility LC (or the amendment, renewal or extension of an
outstanding Facility LC), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in
advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Facility LC, or identifying the Facility LC to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal
or extension (which shall be a Business Day), the date on which such Facility LC is to expire (which 

  

 30 

 
shall comply with paragraph (c) of this Section), the amount of such Facility LC, the name and address of the beneficiary thereof and such other information
as shall be necessary to prepare, amend, renew or extend such Facility LC. If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a
Facility LC. A Facility LC shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Facility LC the Borrower shall be deemed to represent and warrant that), after giving effect to such
issuance, amendment, renewal or extension the sum of the total Revolving Credit Exposures shall not exceed the least of (i) the Aggregate Revolving Loan Commitments, (ii) the Borrowing Base, and (iii) so long as any obligations under the Term Loan
remain unpaid, the TTM EBITDA Amount. 
  
 (c) Expiration
Date. Each Facility LC shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Facility LC (or, in the case of any renewal or extension thereof, one year after such renewal
or extension) and (ii) the date that is five (5) Business Days prior to the Revolving Credit Termination Date. 
  
 (d) Participations. By the issuance of a Facility LC (or an amendment to a Facility LC increasing the amount thereof) and without any further
action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Revolving Lender, and each Revolving Lender hereby acquires from the Issuing Bank, a participation in such Facility LC equal to such Revolving
Lender’s Applicable Revolving Loan Percentage of the aggregate amount available to be drawn under such Facility LC. In consideration and in furtherance of the foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to pay
to the Administrative Agent, for the account of the Issuing Bank, such Revolving Lender’s Applicable Revolving Loan Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in
paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect
of Facility LCs is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Facility LC or the occurrence and continuance of a Default or reduction or termination of
the Revolving Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
  
 (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Facility LC, the Borrower shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the
Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received
prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $500,000.00, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 or
2.05 that such payment be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting
ABR Revolving Borrowing or Swingline Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Revolving Lender of the applicable LC Disbursement, the payment then due from the Borrower 

  

 31 

 
in respect thereof and such Revolving Lender’s Applicable Revolving Loan Percentage thereof. Promptly following receipt of such notice, each Revolving
Lender shall pay to the Administrative Agent its Applicable Revolving Loan Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Revolving Lender (and
Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Revolving Lenders.
Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Revolving Lenders have made
payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Revolving Lenders and the Issuing Bank as their interests may appear. Any payment made by a Revolving Lender pursuant to this paragraph to reimburse the Issuing Bank for
any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 
  
 (f) Obligations Absolute. The Borrower’s obligation to reimburse
LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be 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 Facility LC or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Facility LC proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Facility LC against presentation of a draft or other document that does not comply with the terms of such Facility LC, or (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, constitute a legal or equitable discharge of, or provide a right of set-off against, the Borrower’s
obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Facility LC 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 Facility LC (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 Issuing Bank;
provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the
Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Facility LC comply with the terms
thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank 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 Facility LC, the Issuing Bank 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 Facility LC. 
  

 32 

 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof,
examine all documents purporting to represent a demand for payment under a Facility LC. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the
Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Revolving Lenders with
respect to any such LC Disbursement. 
  
 (h) Interim
Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and
including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided that, if the Borrower fails to reimburse such
LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date
of payment by any Revolving Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Revolving Lender to the extent of such payment. 
  
 (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the
Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Facility LCs to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or
to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an
Issuing Bank under this Agreement with respect to Facility LCs issued by it prior to such replacement, but shall not be required to issue additional Facility LCs. 
  
 (j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the
Borrower receives notice from the Administrative Agent or the Required Revolving Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with LC Exposure representing greater than 66-2/3% of the total LC Exposure) demanding
the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure
as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other
notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance
of the obligations of the Borrower under this Agreement, and Borrower hereby pledges, assigns and grants to the Administrative Agent, on behalf of and for the ratable benefit of the Lenders and the Issuing Bank, a security interest in all of the
Borrower’s right, title and interest in and to all funds which may from time to time be so deposited, to secure the prompt and complete payment and performance of the Obligations. The Administrative 

  

 33 

 
Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the
investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure representing greater
than 66 2/3% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default,
such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived. 
  
 SECTION 2.07. Funding of Borrowings. (a) Each Revolving Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Revolving Lenders; provided
that Swingline Loans shall be made as provided in Section 2.05. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained
with the Administrative Agent in Tulsa, Oklahoma and designated by the Borrower in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section
2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank. 
  
 (b) Unless the Administrative Agent shall have received notice from a Revolving Lender prior to the proposed date of any Borrowing that such Revolving Lender will not make available to the Administrative Agent such
Revolving Lender’s share of such Borrowing, the Administrative Agent may assume that such Revolving Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption,
make available to the Borrower a corresponding amount. In such event, if a Revolving Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Revolving Lender and the Borrower
severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Revolving Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in
the case of the Borrower, the interest rate applicable to ABR Loans. If such Revolving Lender pays such amount to the Administrative Agent, then such amount shall constitute such Revolving Lender’s Loan included in such Borrowing. 

 
 SECTION 2.08. Interest Elections. (a) Each Revolving Borrowing
initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to
convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with
respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the 

  

 34 

 
Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall
not apply to Swingline Borrowings, which may not be converted or continued. 
  
 (b) The Term Loan shall initially be comprised of (i) an ABR Borrowing in the amount of $ 710,000.00 and (ii) the remainder a Eurodollar Borrowing with an initial Interest Period of one (1) month. Thereafter, the
Borrower may elect to convert such Eurodollar Borrowing to a different Type or to continue such Borrowing as a Eurodollar Borrowing and, in the case of any Borrowing that is a Eurodollar Borrowing, may elect Interest Periods therefor, all as
provided in this Section. 
  
 (c) To make an election pursuant to
this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type
resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written
Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower. 
  
 (d) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02: 
  
 (i) the Borrowing to which such Interest Election Request
applies and, if different options are being elected with respect to different portions of a Borrowing, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv)
below shall be specified for each resulting Borrowing); 
  
 (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day; 
  
 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and 
  
 (iv) if the resulting Borrowing is a Eurodollar Borrowing,
the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
  
 If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be
deemed to have selected an Interest Period of one month’s duration. 
  
 (e) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion, if any, of each Borrowing affected by such
Interest Election Request. 
  
 (f) If the Borrower fails to
deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing
shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing, then (i) no outstanding Borrowing may be converted to or 

  

 35 

 
continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto. 
  
 SECTION 2.09. Termination and
Reduction of Revolving Loan Commitments. (a) Unless previously terminated, the Revolving Loan Commitments shall terminate on the Revolving Credit Termination Date. 
  
 (b) The Borrower may at any time terminate, or from time to time reduce, the Revolving Loan Commitments; provided
that (i) each reduction of the Revolving Loan Commitments shall be in an amount that is an integral multiple of $5,000,000.00 and not less than $5,000,000.00 and (ii) the Borrower shall not terminate or reduce the Revolving Loan Commitments if,
after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the aggregate Revolving Credit Exposures would exceed the Aggregate Revolving Loan Commitments. 
  
 (c) The Borrower shall notify the Administrative Agent of any election to
terminate or reduce the Revolving Loan Commitments under paragraph (b) of this Section at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly
following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the
Revolving Loan Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or
prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Revolving Loan Commitments shall be permanent. Each reduction of the Revolving Loan Commitments shall be made ratably among the Revolving
Lenders in accordance with their respective Revolving Loan Commitments. 
  
 SECTION 2.10. Repayment of Loans; Borrowing Base; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Revolving Lender the then unpaid principal amount of
each Revolving Loan on the Revolving Credit Termination Date; (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Credit Termination Date and the first date after such Swingline Loan
is made that is the 15th or last day of a calendar month and is at least two (2) Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then
outstanding; and (iii) to the Administrative Agent for the account of each Term Lender the then unpaid principal amount of the Term Loan on the Term Maturity Date. 
  
 (b) Intentionally Omitted. 
  
 (c) If at any time the total of all Revolving Credit Exposures exceeds the least of (i) the Borrowing Base, (ii) the Aggregate Revolving Loan Commitments,
and (iii) as long as any Obligations under the Term Loan remain unpaid, the TTM EBITDA Threshold, the Borrower shall immediately repay Revolving Loans in an aggregate principal amount sufficient to eliminate any such excess. If the Revolving Loans
have been paid in full, such repayment shall be applied to cash collateralize the Letters of Credit, or, if the Letters of Credit have been cash collateralized, such repayment shall be applied to the Term Loan. 
  

 36 

 (d) The Term Loan shall be repaid in consecutive quarterly payments of principal, each in the aggregate
amount of $500,000.00, payable on the last day of each calendar quarter commencing June 30, 2006 and continuing thereafter to and including the Term Maturity Date. In addition to such scheduled principal installment payments, Borrower may make
voluntary prepayments as and to the extent provided in Section 2.11(a) and shall make mandatory prepayments as provided in Section 2.11(c) (as applicable). 
  
 (e) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of
the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 
  
 (f) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder,
the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
  
 (g) The entries made in the accounts maintained pursuant to paragraph (e) or (f) of this Section shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to
repay the Loans in accordance with the terms of this Agreement. 
  
 (h) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Agent shall prepare and Borrower shall execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment
pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). 
  
 SECTION 2.11. Prepayment of Loans. (a) The Borrower shall have the
right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) and, if a prepayment of the Term Loan, subject to the provisions of paragraph (d). 
  
 (b) The Borrower shall notify the Administrative Agent (and, in the case of
prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three (3) Business Days
before the date of prepayment, (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than
12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of
prepayment is given in connection with a conditional notice of termination of the Revolving Loan Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance
with 

  

 37 

 
Section 2.09. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial
prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to
the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13. 
  
 (c) (i) Notwithstanding the foregoing provisions of this Section 2.11, and subject to clause (ii) below, within two (2) Business Days after receipt
thereof, Borrower shall make a mandatory prepayment in an amount equal to 100% of the Net Cash Proceeds from (1) the sale of any property other than (A) sales of inventory in the ordinary course of business and (B) sales of obsolete or unneeded
equipment in the ordinary course of business in an aggregate less than $2,000,000.00 in any calendar year, (2) the sale or issuance of any Equity Interests to any Person other than Borrower or its Subsidiaries (other than pursuant to the exercise of
stock options issued to employees of Borrower and conversions pursuant to the XYZ Subordinated Loan Documents), (3) the collection of any Large Disputed Accounts, and (4) Extraordinary Receipts to the extent Net Cash Proceeds of Extraordinary
Receipts exceed $2,000,000.00 in the aggregate in any calendar year, provided, however, to the extent insurance proceeds constituting Extraordinary Receipts are applied towards the restoration of damaged property in accordance with any Mortgaged
Properties Security Instrument, said insurance proceeds shall not be deemed Extraordinary Receipts for purposes of this Section 2.11(c)(i)(4). Nothing contained in clause (i)(1) shall nullify the provisions of Section 6.03(b).

  
 (ii) All prepayments described in clause
(i)(1), (i)(2) and (i)(4) shall be applied first to the principal balance of the Term Loan, and after the Term Loan has been paid in full no prepayment shall be required under clause (i)(1), (i)(2) or (i)(4), as the case may be, except to the extent
that Section 2.10(c) requires a prepayment at the time of receipt of Net Cash Proceeds after taking into account all conditions and circumstances at such time, including but not limited to the event that generated such Net Cash Proceeds. All
prepayments described in clause (i)(3) shall be applied (1) until the Term Loan is paid in full, one half to the Term Loan and the remainder to the Revolving Loans and (2) after the Term Loan has been paid in full, all to the Revolving Loans.

  
 (d) All prepayments of the Term Loan shall be applied to the
principal balance thereof in the inverse order of maturity. All prepayments of the Term Loan not required by paragraph (c) that occur on or prior to the date two years after the Closing Date shall be accompanied by (in addition to such prepayment
and any other amounts required by this Section and by Section 2.16) a prepayment fee calculated as follows: (i) for any such prepayment that occurs prior to the date one year after the Closing Date, two percent (2.00%) of the amount prepaid
and (ii) for any such prepayment thereafter but on or prior to the date two years after the Closing Date, one percent (1.00%) of the amount prepaid. 
  

 38 

 SECTION 2.12. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of
each Revolving Lender an Unused Revolving Credit Facility Fee, which shall accrue at the rate per annum set forth below on the daily amount of the unused Revolving Loan Commitment of such Revolving Lender during the period from and including the
Closing Date to but excluding the date on which such Revolving Loan Commitment terminates: 
  

			
	 Senior Leverage Ratio

	  	 Unused Revolving Credit
Facility Fee (bps)

	3 2.00 to 1.00	  	50
	< 2.00 to 1.00	  	50
	< 1.50 to 1.00	  	37.5
	< 1.00 to 1.00	  	37.5

  
 The Unused Revolving
Credit Facility Fee shall be determined in accordance with the foregoing table based on the Senior Leverage Ratio as reflected in the then most recent financial statements delivered pursuant to Section 5.01(a) or (b). Adjustments, if
any, to the Unused Revolving Credit Facility Fee shall be effective on the Margin Adjustment Date. If Borrower fails to deliver the financial statements to the Administrative Agent at the time required pursuant to Section 5.01(a) or
(b), then the Unused Revolving Credit Facility Fee shall be adjusted to the highest fee set forth in the foregoing table until five (5) Business Days after such financial statements are so delivered. Accrued Unused Revolving Credit Facility
Fees shall be payable in arrears on the first day of March, June, September and December of each year and on the date on which the Revolving Loan Commitments terminate, commencing on the first such date to occur after the date hereof;
provided that any Unused Revolving Credit Facility Fees accruing after the date on which the Revolving Loan Commitments terminate shall be payable on demand. All Unused Revolving Credit Facility Fees shall be computed on the basis of a year
of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
  
 (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Revolving Lender a participation fee with respect to its
participations in Facility LCs, which shall accrue at a rate per annum equal to the Applicable Rate (Eurodollar Spread) on the average daily amount of such Revolving Lender’s LC Exposure (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the Closing Date to but excluding the later of the date on which such Revolving Lender’s Revolving Loan Commitment terminates and the date on which such Revolving Lender ceases
to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee at the time of issuance of each Facility LC, which fee shall be paid as separately agreed upon between the Borrower and the Issuing Bank, as well as the Issuing Bank’s
standard fees with respect to the issuance, amendment, renewal or extension of any Facility LC or processing of drawings thereunder. Participation fees accrued through and including the last day of February, May, August and November of each year
shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Closing Date; provided that all such fees shall be payable on the date on which the Revolving Loan Commitments terminate
and any such fees accruing after the date on which the Revolving Loan Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within ten (10) days after demand. All
participation fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
  
 (c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the
times separately agreed upon between the Borrower and the Administrative Agent. 
  

 39 

 (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the
Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of facility fees and participation fees, to the Revolving Lenders. Fees paid shall not be refundable under any circumstances. 

 
 (e) The Borrower shall pay the cost of all audits, inspections, valuations
and/or field examinations conducted pursuant to Section 5.06, provided that if no Event of Default shall be continuing, the Borrower shall not be required to pay for (i) any such audit, inspection, valuation and/or field examination conducted
prior to the date one (1) year after the Closing Date or (ii) more than two (2) such audits, inspections, valuations and/or field examinations per calendar year. 
  
 SECTION 2.13. Interest. (a) The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear
interest at the Alternate Base Rate plus the Applicable Rate. 
  
 (b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. 
  
 (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the
Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any
Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

  
 (d) Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and, in the case of Revolving Loans upon termination of the Revolving Loan Commitments and in the case of the Term Loan on the Term Maturity Date; provided that (i) interest accrued pursuant to
paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal
amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be
payable on the effective date of such conversion. 
  
 (e) All
interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year
of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be
determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 
  
 SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 
  
 (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or 
  

 40 

 (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate, for such
Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period; 
  
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests
the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing;
provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted. 
  

SECTION 2.15. Increased Costs. (a) If any Change in Law shall: 
  
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or 
  
 (ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting
this Agreement or Eurodollar Loans made by such Lender or any Facility LC or participation therein; 
  
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such
Lender or the Issuing Bank of participating in, issuing or maintaining any Facility LC or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. 

 
 (b) If any Lender or the Issuing Bank determines that any Change in Law
regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a
consequence of this Agreement or the Loans made by, or participations in Facility LCs held by, such Lender, or the Facility LCs issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company
with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company for any such reduction suffered. 
  
 (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section
shall be delivered to the Borrower and shall be 

  

 41 

 
conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate
within ten (10) days after receipt thereof. 
  
 (d) Failure or
delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower
shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the
Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to
such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof. 
  
 SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other
than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow,
convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), or (d) the
assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for
the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate plus the Applicable Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of
the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal
amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any
such certificate within ten (10) days after receipt thereof. 
  
 SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums
payable under this Section) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
  

 42 

 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in
accordance with applicable law. 
  
 (c) The Borrower shall
indemnify the Administrative Agent, each Lender and the Issuing Bank, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank,
as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the
amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. 
  
 (d) As soon as practicable after any payment of Indemnified Taxes or Other
Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting
such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
  
 (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly
completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower or the assigning Lender as will permit such payments to be made without withholding or at a reduced rate. 
  
 (f) If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.17, it shall pay over such
refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.17 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or
such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such
Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it
deems confidential) to the Borrower or any other Person. 
  
 SECTION 2.18. Payments Generally; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable
under Section 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon, Tulsa, Oklahoma time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date

  

 43 

 
may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest
thereon. All such payments shall be made to the Administrative Agent at the Administrative Agent’s address specified pursuant to Section 9.01, or at any other office of the Administrative Agent specified in writing by the Administrative
Agent to the Borrower, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made
directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall
be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All
payments hereunder shall be made in dollars. 
  
 (b) If at any
time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, LC Reimbursement Obligations, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of
interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and LC Reimbursement Obligations then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and LC Reimbursement Obligations then due to such parties. 
  
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any
of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued
interest thereon than the proportion received by any other Lender under circumstances where such payment of a greater proportion was not required or contemplated specifically by this Agreement, then the Lender receiving such greater proportion shall
purchase (for cash at face value) participations in the Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders either ratably
in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements and Swingline Loans or in such other manner as specifically provided in this Agreement; provided
that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment
of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The
Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
  
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent
for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative 

  

 44 

 
Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative
Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at
the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 
  
 (e) If any Lender shall fail to make any payment required to be made by it pursuant to Sections 2.05(c),
2.06(d) or (e), 2.07(b), 2.18(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent
for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
  
 SECTION 2.19. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.15, or if the Borrower
is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable
pursuant to Sections 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to
pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
  
 (b) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee
that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Revolving Loan
Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and
Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder (including all amounts payable under Sections 2.15 and 2.17), from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section
2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply.

 ARTICLE III 
  
 Representations and Warranties 
  
 The Borrower represents and warrants to the Lenders that: 
  
 SECTION 3.01. Organization; Powers. Each of the Borrower and its Subsidiaries is duly organized, validly existing and
in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably
be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required. 
  
 SECTION 3.02. Authorization; Enforceability. The Transactions are within the Borrower’s corporate powers and
have been duly authorized by all necessary corporate and, if required, stockholder action. This Agreement has been duly executed and delivered by the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a
proceeding in equity or at law. 
  
 SECTION 3.03. Governmental
Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect,
(b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of the Borrower or any of its Subsidiaries or any order of any Governmental Authority, (c) will not violate or result in a default under
any indenture, agreement or other instrument binding upon the Borrower or any of its Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Subsidiaries, and (d) will not result
in the creation or imposition of any Lien on any asset of the Borrower or any of its Subsidiaries. 
  
 SECTION 3.04. Financial Condition; No Material Adverse Change. (a) The Borrower has heretofore furnished to the Lenders its consolidated balance
sheet and statements of income, stockholders equity and cash flows (i) as of and for the fiscal year ended May 31, 2005, reported on by Ernst & Young LLP, independent public accountants, and (ii) as of and for the fiscal quarter and the portion
of the fiscal year ended August 31, 2005, certified by its chief financial officer. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its
consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of the statements referred to in clause (ii) above. 
  
 (b) Since August 31, 2005, there has been no adverse change in the business,
assets, operations, prospects or condition, financial or otherwise, of the Borrower and its Subsidiaries, taken as a whole, that could reasonably be expected to have a Material Adverse Effect. 
  
 SECTION 3.05. Properties. (a) Each of the Borrower and the Guarantors
has good title to, or valid leasehold interests in, all its real and personal property material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently 

  

 46 

 
conducted or to utilize such properties for their intended purposes and except as set forth on Schedule 3.05. 
  
 (b) Each of the Borrower and the Guarantors owns, or is licensed to use, all
trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and Guarantors does not infringe upon the rights of any other Person, except for any such infringements that,
individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 
  
 SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any of its Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined,
could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve this Agreement or the Transactions. 
  
 (b) Except as discussed in the Disclosed Matters, in the ordinary course of
its business the officers of the Borrower consider the effect of Environmental Laws on the business of the Borrower and its Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities to which the Borrower or its
Subsidiaries may be subject due to Environmental Laws. On the basis of this consideration, except with respect to matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the
Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental
Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability. Except as discussed in the Disclosed Matters, neither the Borrower nor any Subsidiary has
received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal or state investigation evaluating whether any remedial action is
needed to respond to a release of any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a Material Adverse Effect. 
  
 (c) Since the date of this Agreement, there has been no change in the status
of the Disclosed Matters that, individually or in the aggregate, has resulted in, or materially increased the likelihood of, a Material Adverse Effect. 
  
 SECTION 3.07. Compliance with Laws and Agreements; Default. Each of the Borrower and its Subsidiaries is in compliance with all laws, regulations
and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably
be expected to result in a Material Adverse Effect. No Default has occurred and is continuing. 
  
 SECTION 3.08. Investment and Holding Company Status. Neither the Borrower nor any of its Subsidiaries is (a) an “investment company” as defined in, or subject to regulation under, the Investment
Company Act of 1940 or (b) a “holding company” or a “subsidiary company” of a “holding company”, or an “affiliate” of a “holding company” or of a “subsidiary company” of a 

  

 47 

 
“holding company” as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935. 
  
 SECTION 3.09. Taxes. Each of the Borrower and its Subsidiaries has
timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with Agreement Accounting Principles and as to which no Lien exists or (b) to the extent that the failure to do so
could not reasonably be expected to result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any Taxes or other governmental charges are adequate. 
  
 SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit
obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $ 500,000.00
the fair market value of the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of
the date of the most recent financial statements reflecting such amounts, exceed by more than $ 500,000.00 the fair market value of the assets of all such underfunded Plans. Neither the Borrower nor any other member of the Controlled Group has
incurred, or is reasonably expected to incur, any withdrawal liability to Multiemployer Plans in excess of $500,000.00 in the aggregate. Each Plan complies in all material respects with all applicable requirements of law and regulations, neither the
Borrower nor any other member of the Controlled Group has withdrawn from any Plan or initiated steps to do so, and no steps have been taken to reorganize or terminate any Plan. 
  
 SECTION 3.11. Plan Assets; Prohibited Transactions. The Borrower is not an entity deemed to hold “plan
assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code), and neither the
execution of this Agreement nor the extending of Loans or issuance of Facility LCs hereunder gives rise to a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code. 
  
 SECTION 3.12. Disclosure. The Borrower has disclosed to the Lenders
all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material
Adverse Effect. None of the reports, financial statements, certificates or other information furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or delivered
hereunder (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. 

 

 48 

 SECTION 3.13. Subsidiaries. Schedule 3.13 contains an accurate list of all Subsidiaries of
the Borrower as of the date of this Agreement, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by the Borrower or other Subsidiaries. All of the
issued and outstanding shares of capital stock or other ownership interests of such Subsidiaries have been (to the extent such concepts are relevant with respect to such ownership interests) duly authorized and issued and are fully paid and
non-assessable. 
  
 SECTION 3.14. Material Agreements.
Neither the Borrower nor any Subsidiary is a party to any agreement or instrument or subject to any charter or other corporate restriction which could reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary
is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in (i) any agreement to which it is a party, which default could reasonably be expected to have a Material Adverse Effect or
(ii) any agreement or instrument evidencing or governing Indebtedness, including but not limited to any of the Loan Documents. 
  
 SECTION 3.15. Subordinated Indebtedness. The Obligations constitute senior indebtedness which is entitled to the benefits of the subordination
provisions of all outstanding Subordinated Indebtedness. 
  
 SECTION 3.16. Post-Retirement Benefits. The present value of the expected cost of post-retirement medical and insurance benefits payable by the Borrower and its Subsidiaries to its employees and former employees, as estimated by the
Borrower in accordance with procedures and assumptions deemed reasonable by the Required Lenders, does not exceed $500,000.00. 
  
 SECTION 3.17. Insurance. The certificate signed by the President or Chief Financial Officer of the Borrower, that attests to the existence and
adequacy of, and summarizes, the property and casualty insurance program carried by the Borrower with respect to itself and its Subsidiaries and that has been furnished by the Borrower to the Administrative Agent and the Lenders, is complete and
accurate. This summary includes the insurer’s or insurers’ name(s), policy number(s), expiration date(s), amount(s) of coverage, type(s) of coverage, exclusion(s), and deductibles. This summary also includes similar information, and
describes any reserves, relating to any self-insurance program that is in effect. 
  
 SECTION 3.18. Solvency. (i) Immediately after the consummation of the transactions to occur on the date hereof and immediately following the making of each Loan, if any, made on the date hereof and after giving
effect to the application of the proceeds of such Loans, (a) the fair value of the assets of the Borrower and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or
otherwise, of the Borrower and its Subsidiaries on a consolidated basis; (b) the present fair saleable value of the property of the Borrower and its Subsidiaries on a consolidated basis will be greater than the amount that will be required to pay
the probable liability of the Borrower and its Subsidiaries on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (c) the Borrower and
its Subsidiaries on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (d) the Borrower and its Subsidiaries on a consolidated
basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof. 
  

 49 

 (ii) The Borrower does not intend to, or to permit any of its Subsidiaries to, and does not believe that
it or any of its Subsidiaries will, incur debts beyond its ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it or any such Subsidiary and the timing of the amounts of cash to be
payable on or in respect of its Indebtedness or the Indebtedness of any such Subsidiary. 
  
 SECTION 3.19. Payment and Performance Bonds. Attached hereto as Schedule 3.19 are true and complete copies of all payment and performance bonds to which Borrower or any of the Subsidiaries is a party as
of the Closing Date. No such bonds (or any application or related documents) currently evidence any collateral or security of any kind or nature in favor of the surety thereunder other than Facility LCs that have been issued in connection with
certain of those bonds. 
  
 SECTION 3.20. Commercial Tort
Claims. As of the Closing Date, neither the Borrower nor any of the Subsidiaries owns or has any interest in any “commercial tort claim” (as that term is defined 12A Okla. Stat. §1-9-102(a)(13) as of the Closing Date) that has not
been specifically described in a Security Agreement as part of the collateral thereunder.

 ARTICLE VIII 
  
 The Administrative Agent 
  
 SECTION 8.01 Appointment. Each of the Lenders and the Issuing Bank
hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with
such actions and powers as are reasonably incidental thereto. 
  
 SECTION 8.02 Administrative Agent and Lender. The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were
not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative
Agent hereunder. 
  
 SECTION 8.03 Collateral; Required
Lenders. (a) Each Lender hereby irrevocably ratifies and accepts the Collateral Documents in effect as of the Closing Date and authorizes and directs Administrative Agent to enter into all additional Collateral Documents for the benefit of such
Lender. Each Lender hereby agrees, and each holder of any Note by the acceptance thereof will be deemed to agree, that, except as otherwise set forth in Section 9.02(b), any action taken by the Required Lenders, in accordance with the
provisions of this Agreement or the Collateral Documents, and the exercise by the Required Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon
all of Lenders. Administrative Agent is hereby authorized on behalf of all of Lenders, without the necessity of any notice to or further consent from any Lender from time to time prior to an Event of Default, to take any action with respect to any
Collateral or Collateral Documents which may be necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Collateral Documents. 
  
 (b) Each Lender hereby irrevocably authorizes Administrative Agent, at its option and in its discretion, (i) to release any
Lien on any property granted to or held by Administrative Agent under any Loan Document (A) upon termination of the Revolving Loan Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the
expiration or termination of all Facility LCs, (B) that is sold or to be sold as part of or in connection with any sale permitted hereunder or under any other Loan Document, (C) subject to Section 9.02(b), if approved, 

  

 67 

 
authorized or ratified in writing by the Required Lenders, or (D) in connection with any foreclosure sale or other disposition of Collateral after the
occurrence of an Event of Default; and (ii) to subordinate any Lien on any property granted to or held by Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by this Agreement or any other Loan
Document. Upon request by Administrative Agent at any time, each Lender will confirm in writing Administrative Agent’s authority to release or subordinate its interest in particular types or items of Collateral pursuant to this Article
VIII. Subject to the foregoing, Administrative Agent shall (and is hereby irrevocably authorized by each Lender, to) execute such documents as may be necessary to evidence the release or subordination of the Liens granted to Administrative Agent
for the benefit of Administrative Agent and Lenders herein or pursuant hereto upon the applicable Collateral; provided that (i) Administrative Agent shall not be required to execute any such document on terms which, in Administrative Agent’s
opinion, would expose Administrative Agent to or create any liability or entail any consequence other than the release or subordination of such Liens without recourse or warranty and (ii) such release or subordination shall not in any manner
discharge, affect or impair the Obligations or any Liens upon (or obligations of Borrower or any other Credit Party in respect of) all interests retained by Borrower or any other Credit Party, including the proceeds of the sale, all of which shall
continue to constitute part of the Collateral. In the event of any sale or transfer of Collateral, or any foreclosure with respect to any of the Collateral, Administrative Agent shall be authorized to deduct all expenses reasonably incurred by
Administrative Agent from the proceeds of any such sale, transfer or foreclosure. 
  
 (c) Administrative Agent shall have no obligation whatsoever to any Lender or any other Person to assure that the Collateral exists or is owned by Borrower or any other Credit Party or is cared for, protected or
insured or that the Liens granted to Administrative Agent herein or in any of the Collateral Documents or pursuant hereto or thereto have been properly or sufficiently or lawfully created, perfected, protected or enforced or are entitled to any
particular priority, or to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure or fidelity any of the rights, authorities and powers granted or available to Administrative Agent in this Article
VIII or in any of the Collateral Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, Administrative Agent may act in any manner it may deem appropriate, in its sole
discretion, given Administrative Agent’s own interest in the Collateral as one of the Lenders and that Administrative Agent shall have no duty or liability whatsoever to Lenders. 
  
 (d) Each Lender hereby appoints each other Lender as agent for the purpose of perfecting Lenders’ security interest in
assets which, in accordance with Article 9 of the UCC can be perfected only by possession. Should any Lender (other than Administrative Agent) obtain possession of any such Collateral, such Lender shall notify Administrative Agent thereof, and,
promptly upon Administrative Agent’s request therefor shall deliver such Collateral to Administrative Agent or in accordance with Administrative Agent’s instructions. 
  
 SECTION 8.04 Duties. The Administrative Agent shall not have any duties or obligations except those expressly set
forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing, (b) the
Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing
as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the Administrative Agent shall
not have any duty to 

  

 68 

 
disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or
obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have
knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth
in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 
  
 SECTION 8.05 Communications; Counsel. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon,
any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it
orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants
and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
  
 SECTION 8.06 Sub-Agents. The Administrative Agent may perform any and all its duties and exercise its rights and
powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties.
The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication
of the credit facilities provided for herein as well as activities as Administrative Agent. 
  
 SECTION 8.07 Successor. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 8.07, the Administrative Agent may resign at any time by notifying the
Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and
shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor
Administrative Agent which shall be a bank with an office in Tulsa, Oklahoma, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to 

  

 69 

 
its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions
of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while
it was acting as Administrative Agent. 
  
 SECTION 8.08
Lenders’ Reliance; Decisions. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall
from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder. 
  
 ARTICLE IX 
  
 Miscellaneous 
  
 SECTION 9.01. Notices. (a) Except in the case of notices and other
communications expressly permitted to be given by telephone (and subject to paragraph (b) below), all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by
certified or registered mail or sent by telecopy, as provided in the signature pages hereto. 
  
 (b) Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall
not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it
hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications. 
  
 (c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to
the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. 
  
 SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the
Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph
(b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting 

  

 70 

 
the generality of the foregoing, the making of a Loan or issuance of a Facility LC shall not be construed as a waiver of any Default, regardless of whether
the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 
  
 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the written consent of the Required Lenders; provided that (i) no such agreement shall (A) increase the Revolving Loan Commitment of any

postpone the scheduled date of expiration of any Revolving Loan Commitment, without the written consent of each Lender affected thereby, (D) change Section 2.18(b) or (c) in a manner that would alter the sharing of payments required
thereby, without the written consent of each Lender, (E) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive,
amend or modify any rights hereunder or make any determination or grant any consent hereunder, or (F) release any Guarantor from any Subsidiary Guaranty or release the Liens on a Substantial Portion of the Collateral except in accordance with the
terms of any Loan Document, without the written consent of each Lender and (ii) and no such agreement shall change Sections 2.10(c), 2.11(c) or 2.11(d), the definition of “TTM EBITDA Amount”, or any of the definitions used therein without
the written consent of the Required Term Lenders; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder
without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be.

this Section, or in connection with the Loans made or Facility LCs issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Facility LCs. 
  
 (b) The Borrower shall indemnify the Administrative Agent, the Issuing Bank
and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related
expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated 

  

 71 

 
hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions
contemplated hereby, (ii) any Loan or Facility LC or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Facility LC if the documents presented in connection with such demand do not
strictly comply with the terms of such Facility LC), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related

by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. 
  
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline
Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Applicable Percentage (determined as of the time
that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such. 
  
 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions,
any Loan or Facility LC or the use of the proceeds thereof. 
  
 (e) All amounts due under this Section shall be payable not later than five (5) days after written demand therefor.

 (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement 

  

 72 

 
(including all or a portion of its Revolving Loan Commitment (if any) and the Loans at the time owing to it) with the prior written consent (such consent not
to be unreasonably withheld) of: 
  
 (A) the
Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; 
  
 (B) the Administrative Agent, provided that no
consent of the Administrative Agent shall be required for an assignment of (x) any Revolving Loan Commitment to an assignee that is a Revolving Lender immediately prior to giving effect to such assignment and (y) all or any portion of the Term Loan
to a Lender, an Affiliate of a Lender or an Approved Fund; and 
  
 (C) the Issuing Bank, provided that no consent of the Issuing Bank shall be required for an assignment of all or any portion of the Term Loan. 
  
 (ii) Assignments shall be subject to the following additional conditions: 
  
 (A) except in the case of an assignment to a Lender or an
Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Revolving Loan Commitment or Loans of any Class, the amount of the Revolving Loan Commitment or Loans of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than the lesser of (i) $5,000,000.00 or (ii) the remaining amount of
the assigning Lender’s Revolving Loan Commitment (calculated as of the date of such assignment), if any, and outstanding Loans, unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of
the Borrower shall be required if an Event of Default has occurred and is continuing; 
  
 (B) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, each partial assignment shall be made

Lender’s rights and obligations in respect of one Class of Revolving Loan Commitments or Loans; 
  
 (C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee of $3,500.00; and 
  
 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

entity or an Affiliate of an entity that administers or manages a Lender. 
  

 73 

 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this

a Revolving Lender and/or Term Lender, as the case may be, under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this
Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of
Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement
as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section. 
  
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each
Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Loan Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to
the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any
reasonable time and from time to time upon reasonable prior notice. 
  
 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and
Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.05(c), 2.06(d) or (e),
2.07(b), 2.18(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all
accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 
  
 (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Bank or the Swingline
Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Revolving Loan Commitment
and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and
(C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement;
provided that 

  

 74 

 
such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16
and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section
9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. 
  
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.15 or 2.17 than the applicable
Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply
with Section 2.17(e) as though it were a Lender. 
  
 (d)
Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto. 
  
 (e) The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any
prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries. 
  
 SECTION 9.05. Disclosure. The Borrower and each Lender hereby (i) acknowledge and agree that (a) one or more Affiliates of JPMorgan Chase are or
may become direct or indirect equity investors in Borrower, and (b) JPMorgan Chase and/or its Affiliates from time to time may hold other investments in, make other loans to or have other relationships with Borrower, and (ii) waive any liability of
JPMorgan Chase or such Affiliate to the Borrower or any Lender, respectively, arising out of or resulting from such investments, loans or relationships other than liabilities arising out of the gross negligence or willful misconduct of JPMorgan
Chase or its Affiliates. 
  
 SECTION 9.06. Survival. All
covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other
parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Facility LCs, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Facility LC is outstanding and so long as the Revolving Loan Commitments have not expired or terminated.
The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of 

  

 75 

 
the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Facility LCs and the Revolving Loan Commitments or the
termination of this Agreement or any provision hereof. 
  
 SECTION
9.07. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall
constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all
previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
  
 SECTION 9.08. Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
  
 SECTION 9.08. Right of Set-off. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by
such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall
have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of set-off) which such Lender may have.

  
 SECTION 9.09. Governing Law; Jurisdiction; Consent to
Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of Oklahoma. 
  
 (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any United States
federal court or Oklahoma state court sitting in Tulsa, Oklahoma, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such state or, to the extent permitted by law, in such federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the
Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any 

  

 76 

 
action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction. 
  
 (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of
this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
  
 (d) Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
  
 SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE
THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
  
 SECTION 9.11. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 
  
 SECTION 9.12. Confidentiality. (a) Each of the Administrative Agent,
the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ and Approved Funds’ directors, officers, employees and
agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the
exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any
assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to
the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the
Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its 

  

 77 

 
business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person
would accord to its own confidential information. 
  
 (b) EACH
LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.12(a) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE BORROWER AND ITS RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, THAT IT
HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES
LAWS. 
  
 SECTION 9.13. Interest Rate Limitation.
Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of
interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan
but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such
cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender. 
  
 SECTION 9.14. USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address
of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

 88First Amendment

 Exhibit 10.1 
  
 FIRST AMENDMENT TO CREDIT AGREEMENT 
  

THIS AMENDMENT TO CREDIT AGREEMENT (this “Amendment”) is entered into as of December 22, 2005, by and between COLUMBIA SPORTSWEAR COMPANY, an
Oregon corporation (“Borrower”), and WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”). 
  
 RECITALS 
  
 WHEREAS, Borrower is currently indebted to Bank pursuant to the terms and conditions of that certain Credit Agreement between Borrower and Bank dated as of December 16, 2004, as amended from time to time (“Credit Agreement”).

  
 WHEREAS, Bank and Borrower have agreed to certain changes in
the terms and conditions set forth in the Credit Agreement and have agreed to amend the Credit Agreement to reflect said changes. 
  
 NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree that the Credit
Agreement shall be amended as follows: 
  
 1. The definition of
“Available Credit” set forth in Section 1.1 of Article I of the Credit Agreement is hereby deleted in its entirety and the following substituted therefor: 
  
 “ ‘Available Credit’ means, at any time, the amount by which the aggregate of the
outstanding principal amount of the Loans at such time is less than (a) $100,000,000.00 during the period of August 15 through November 15 of the calendar year, and (b) $25,000,000.00 at all other times from the date of this
Agreement through the Maturity Date.” 
  
 2. The definition
of “Maturity Date” set forth in Section 1.1 of Article I of the Credit Agreement is hereby deleted in its entirety and the following substituted therefor: 
  
 “ ‘Maturity Date’ means July 1, 2007.” 
  
 3. Section 2.1(a) of Article 2 of the Credit Agreement is hereby deleted
in its entirety and the following substituted therefor: 
  
 “(a) On the terms and subject to the conditions contained in this Agreement, Bank agrees to make loans (each a “Loan,” and collectively, “Loans”) to Borrower from time to time until the
Maturity Date in an aggregate amount not to exceed at any time outstanding $100,000,000.00 during the period of August 15 through November 14 of the calendar year, and (ii) $25,000,000.00 at all other times from the date of this
Agreement through the Maturity Date. Borrower may, from time to time, borrow, 

 
partially or wholly repay the outstanding Loans, and reborrow, subject to all the limitations, terms and conditions contained herein.” 
  
 4. This Amendment shall be effective upon Bank’s receipt of each of the
following, duly executed and in form and substance satisfactory to Bank, by no later than December 22, 2005: 
  
 (a) a promissory note dated as of December 22, 2005 (which promissory note shall replace and be deemed the Note defined in and made
pursuant to the Credit Agreement); 
  
 (b) a
guaranty from Columbia Sportswear USA corporation in the amount of $100,000,000.00; and 
  
 (c) all other contracts, instruments and documents required by Bank to evidence such changes, including without limitation any
authorization documents required in connection therewith. 
  
 5.
Except as specifically provided herein, all terms and conditions of the Credit Agreement remain in full force and effect, without waiver or modification. All terms defined in the Credit Agreement shall have the same meaning when used in this
Amendment. This Amendment and the Credit Agreement shall be read together, as one document. 
  
 6. Borrower hereby remakes all representations and warranties contained in the Credit Agreement and reaffirms all covenants set forth therein. Borrower further certifies that as of the date of this Amendment there
exists no Event of Default as defined in the Credit Agreement, nor any condition, act or event which with the giving of notice or the passage of time or both would constitute any such Event of Default. 
  
 UNDER OREGON LAW, MOST AGREEMENTS, PROMISES AND COMMITMENTS MADE BY BANK CONCERNING
LOANS AND OTHER CREDIT EXTENSIONS WHICH ARE NOT FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OR SECURED SOLELY BY THE BORROWER’S RESIDENCE MUST BE IN WRITING, EXPRESS CONSIDERATION AND BE SIGNED BY BANK TO BE ENFORCEABLE. 
  
 IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed as of the day and year first written above.
