(iv) Any Revolving Lender that accepts an offer to it by Lufkin to increase its Revolving Commitment pursuant to this Section 2.01(c) shall, in each case, execute a Commitment Increase Agreement with Lufkin and the Administrative Agent, whereupon such Revolving Lender shall be bound by and entitled to the benefits of this Agreement with respect to the full amount of its Revolving Commitment as so increased, and the definition of Revolving Commitment in Section 1.01 shall be deemed to be amended to so increase the Revolving Commitment of such Revolving Lender.

(v) On the effective date of an Acceptance, the applicable New Revolving Lender, or the effectiveness of a Commitment Increase Agreement, the applicable Revolving Lender, as the case may be (the “Re-Allocation Date”), will acquire LC Exposure described under clause (b) of the definition of LC Exposure in an amount equal to the percentage of all such outstanding LC Exposures that such Person’s increase in Revolving Commitment occurring on the Re-Allocation Date bears to all Revolving Commitments in effect on the Re-Allocation Date, and each other Revolving Lender shall be deemed to sell to such New Revolving Lender or Lenders, as the case may be, such other Lender’s pro rata share of such outstanding LC Exposure acquired hereunder by such New Revolving Lender or Lenders. All Revolving Loans (including conversions or continuations of Revolving Loans) made by each Revolving Lender, and LC Exposure purchased by each Revolving Lender, shall be pro rata to each Revolving Lender based on its respective Revolving Commitment in effect on and after such Re-Allocation Date (except to the extent that any such pro rata borrowings would result in any Revolving Lender making an aggregate principal amount of Revolving Loans in excess of its Revolving Commitment, in which case such excess amount will be allocated to, and made by, such New Revolving Lender and/or Lenders with such increased Revolving Commitments to the extent of, and pro rata based on, their respective Revolving Commitments), and continuations of Eurodollar Loans outstanding on such Re-Allocation Date shall be effected by repayment of such Eurodollar Loans on the last day of the Interest Period applicable thereto and the making of new Eurodollar Loans pro rata based on the respective Revolving Commitments in effect on and after such Re-Allocation Date. In the event that on any such Re-Allocation Date there is an unpaid principal amount of Eurodollar Loans, such Eurodollar Loans shall remain outstanding with the respective holders thereof until the expiration of their respective Interest Periods (unless Lufkin elects to prepay any thereof in accordance with the applicable provisions of this Agreement), and interest on and repayments of such Eurodollar Loans will be paid thereon to the respective Revolving Lenders holding such Eurodollar Loans pro rata based on the respective principal amounts thereof outstanding.

(vi) Notwithstanding anything to the contrary in this Section 2.01(c), no Lender shall have any obligation to increase its Revolving Commitment unless it agrees to do so in its sole discretion.

SECTION 2.2. Loans and Borrowings.

(a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments of that Class. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations (if any) hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Subject to Section 2.15, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the applicable Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the applicable Borrower to repay such Loan in accordance with the terms of this Agreement. Each Swingline Loan shall be an ABR Loan.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $5,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $50,000 and not less than $250,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments of that Class or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.05(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of ten (10) Eurodollar Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, neither Borrower shall be entitled to request, or to elect to convert or continue, any Borrowing as a Eurodollar Borrowing if a Default shall have occurred and be continuing, or if the Interest Period requested with respect thereto would end after the scheduled Maturity Date, or if, after giving effect to such Interest Period, the aggregate principal amount of all Term Loans with Interest Periods ending after the next installment payment date for Term Loans would exceed the aggregate principal amount of all Term Loans then permitted to be outstanding.

SECTION 2.3. Requests for Borrowings. To request a Borrowing, the applicable 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, (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the same Business Day; or (c) in the case of a Swingline Loan, as provided in Section 2.04; provided that any such notice of a ABR Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.05(e) may be given not later than 11:00 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 Borrowing Request signed by the applicable Borrower. Neither the Administrative Agent nor any Lender shall incur any liability to either Borrower in acting upon any telephonic notice referred to above which the Administrative Agent believes in good faith to have been given by a Borrower or for otherwise acting in good faith under this Section 2.03. 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 account to which funds are to be disbursed, which account shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, the applicable 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 Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.4. Swingline Loans.

(a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to Lufkin from time to time during the Availability Period in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $5,000,000 or (ii) the aggregate Revolving Credit Exposures exceeding the aggregate Revolving Commitments. Each Swingline Loan shall be made in an amount of $250,000 or an integral multiple of $50,000 in excess thereof and shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin. Within the foregoing limits and subject to the terms and conditions set forth herein, Lufkin may borrow, repay and reborrow Swingline Loans.

(b) To request a Swingline Loan, Lufkin shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 11:00 a.m., New York City time, on the day of the proposed Swingline Loan; if such telephonic notice is received later than 11:00 a.m., New York City time, the request shall be deemed to be a request for a Swingline Loan to be made on the next Business Day. 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 Lufkin. The Swingline Lender shall make each Swingline Loan available to Lufkin by means of a credit to the general deposit account of Lufkin 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 2.05(d), by remittance to the applicable Issuing Bank) by 2:00 p.m., New York City time, on the requested date of such Swingline Loan. Lufkin shall repay the principal amount of each Swingline Loan (together with all accrued and unpaid interest) no later than 2:00 p.m., New York City time, on the date that is the earlier of (i) one week after the date on which such Swingline Loan is made and (ii) the Maturity Date; provided that on each date that a Revolving Borrowing is made, Lufkin shall repay all Swingline Loans then outstanding.

(c) The Swingline Lender may, at its option, by written notice to the Administrative Agent not later than 11:00 a.m., New York City time, on any Business Day, before or after the maturity of the Swingline Loan (regardless of whether a Default or an Event of Default has, or has not, occurred and is continuing) require the Revolving Lenders to acquire, without recourse or warranty, participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice from the Swingline Lender shall specify the aggregate principal amount of Swingline Loans in which Revolving Lenders will be required to participate. Promptly upon receipt of such notice from the Swingline Lender, the Administrative Agent will give notice thereof to each Revolving Lender, specifying in such notice such Revolving Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of such notice from the Administrative Agent properly delivered as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Revolving Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Revolving Lender acknowledges and agrees that, subject to Section 2.04(e), upon receipt of such notice properly delivered, its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute, unconditional and irrevocable shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default or reduction or termination of the Revolving Commitments, shall be made without any offset, abatement, withholding or reduction whatsoever, may not be terminated, suspended or delayed for any reason whatsoever, shall not be subject to qualification or exception and shall be made in accordance with the terms of this Agreement. 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 2.06(a) with respect to Revolving Loans made by such Revolving Lender (and Sections 2.06(a) and 2.06(b) 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 Lufkin of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter (i) payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender and (ii) the Revolving Lenders’ respective interests in such Swingline Loans, and the remaining interest of the Swingline Lender in such Swingline Loans shall in all respects be treated as Revolving Loans under this Agreement, except that Swingline Loans shall be due and payable by Lufkin on the dates referred to in Section 2.04(b). Any amounts received by the Swingline Lender from Lufkin (or other Person on behalf of Lufkin) in respect of a Swingline Loan after receipt by the Swingline Loan 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 Lufkin for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve Lufkin of any default in the payment thereof.

(d) If any Revolving Lender does not pay any amount that it is required to pay pursuant to this Section 2.04 and to the extent not otherwise provided for in Section 2.22, as applicable, promptly upon the Swingline Lender’s demand therefor, (a) the Swingline Lender shall be entitled to recover such amount on demand from such Revolving Lender, together with interest thereon, at the Federal Funds Effective Rate for the first three Business Days, and thereafter at the Alternate Base Rate, for each day from the date of such demand, if made prior to 2:00 p.m., New York City time, on any Business Day, or, if made at any later time, from the next Business Day following the date of such demand, until the date such amount is paid in full to the Swingline Lender by such Revolving Lender and (b) the Swingline Lender shall be entitled to all interest payable by Lufkin to such Revolving Lender on such amount until the date on which such amount is received by the Swingline Lender from such Revolving Lender. Moreover, any Revolving Lender that shall fail to make available the required amount shall not be entitled to vote on or consent to or approve any matter under this Agreement and the other Loan Documents until such amount with interest is paid in full to the Swingline Lender by such Revolving Lender. Without limiting any obligations of any Revolving Lender pursuant to this Section 2.04(d), but subject to Section 9.17, if any Revolving Lender does not pay such corresponding amount promptly upon the Swingline Lender’s demand therefor, the Swingline Lender shall notify Lufkin and Lufkin shall promptly repay such corresponding amount to the Swingline Lender together with accrued interest thereon at the applicable rate on such Swingline Loans.

(e) No Revolving Lender shall be obligated to purchase a participation in any Swingline Loan pursuant to Section 2.04(c), if such Lender proves that (a) any one or more of the applicable conditions specified in Section 4.03 was not satisfied at the time such Swingline Loan was made (unless such condition was waived in accordance with the terms of this Agreement) and (b) such Revolving Lender had notified the Swingline Lender in a writing received by the Swingline Lender at least one Business Day prior to the time that it made such Swingline Loan that the Swingline Lender was not authorized to make such Swingline Loan because any such condition was not satisfied and stating with specificity the reason therefor.

SECTION 2.5. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, Lufkin may request the issuance of Letters of Credit for its own account and for the account of its Subsidiaries, 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, Letter of Credit Agreement or other agreement submitted by Lufkin to, or entered into by Lufkin with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), Lufkin 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 Letter of Credit, or identifying the Letter of Credit 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 Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, Lufkin also shall submit a Letter of Credit Agreement or a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit Lufkin shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) the aggregate LC Exposures shall not exceed $30,000,000, and (ii) the sum of the total Revolving Credit Exposures shall not exceed the total Revolving Commitments. On each day during the period commencing with the issuance of any Letter of Credit and until such Letter of Credit shall have expired or been terminated, the Revolving Commitment of each Revolving Lender shall be deemed to be utilized for all purposes of this Agreement in an amount equal to such Revolving Lender’s Applicable Percentage of the sum of (i) the undrawn amount of such Letter of Credit on such day plus (ii) the amount of all LC Disbursements that have not been reimbursed by or on behalf of Lufkin on such day with respect to such Letter of Credit. Notwithstanding anything in this Section 2.05, the Issuing Bank shall be under no obligation to issue, renew, amend or extend a Letter of Credit if there is a Defaulting Lender, unless the Issuing Bank has entered into arrangements satisfactory to the Issuing Bank with Lufkin or the Defaulting Lender to eliminate the Issuing Bank’s risk with respect to such Defaulting Lender.

(c) Expiration Date. Each Letter of Credit 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 Letter of Credit (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 scheduled Maturity Date, provided that any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date that is five (5) Business Days prior to the scheduled Maturity Date). After the termination of the Availability Period, no Letter of Credit may be issued, amended, renewed or extended. After the termination of the Availability Period, all terms of this Agreement (other than Sections 2.01, 2.02, 2.03, 2.04, 2.06, 2.07, 2.08, 2.11, 2.12, 2.17, and 2.21, Article 3 and Article 5) shall survive and remain in effect for the benefit of the Secured Parties and all other parties benefited thereby, notwithstanding the termination of the Availability Period, until each Lender’s LC Exposure is zero and all obligations of Lufkin, under Section 2.04 and otherwise, with respect to any such LC Exposure have been fully and finally satisfied.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or any Lender, the Issuing Bank hereby grants to each Revolving Lender, and each Revolving Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Revolving Lender’s Applicable Percentage of the total Revolving Commitments the aggregate amount available to be drawn under such Letter of Credit. 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 Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by Lufkin on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to Lufkin for any reason. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the 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 Letter of Credit, Lufkin shall reimburse such LC Disbursement by paying to the Administrative Agent for the account of the Issuing Bank in immediately available funds an amount equal to such LC Disbursement (i) not later than 12:00 noon New York City time on the date that such LC Disbursement is made, if Lufkin shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time on such date, or (ii) if such notice has not been received by Lufkin prior to such time on such date, then not later than 12:00 noon New York City time on the Business Day immediately following the day that Lufkin receives such notice; provided that, if such LC Disbursement is $1,000,000 or more, Lufkin may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 or 2.06 that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, Lufkin’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. The Revolving Lenders may, but shall not be obligated to, at any time deem that Lufkin has requested an ABR Borrowing to satisfy any LC Disbursement, and the Revolving Lenders may without further action by Lufkin satisfy such LC Disbursement (without regard to the conditions precedent to a Loan, the minimum size of a Loan or other matters) through an ABR Borrowing. All rights, powers, benefits and privileges of this Agreement and the other Loan Documents with respect to the Revolving Loans, all security therefor and guaranties thereof and all restrictions, provisions for repayment or acceleration and all other covenants, warranties, representations and agreements of Lufkin or any other Loan Party contained in this Agreement or any other Loan Document with respect to the Revolving Loans shall apply to each LC Disbursement. If Lufkin 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 Lufkin in respect thereof and such Revolving Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Revolving Lender shall pay to the Administrative Agent for the account of the Issuing Bank such Revolving Lender’s Applicable Percentage of the payment then due from Lufkin, in the same manner as provided in Section 2.06 with respect to Loans made by such Revolving Lender (and Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders). Promptly following receipt by the Administrative Agent of any payment from Lufkin 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 (other than Defaulting 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 Loans as contemplated above) shall not constitute a Loan and shall not relieve Lufkin of its obligation to reimburse such LC Disbursement. If the amount drawn under any Letter of Credit is in non-United States currency (“foreign currency”), Lufkin shall pay the United States dollar equivalent of the amount computed at the Issuing Bank’s selling rate, as of the date of Borrower’s payment, for cable transfers of such foreign currency to the place of payment; provided, further, that if, for any reason, the Issuing Bank has no selling rate for cable transfers of that currency to such place on the payment date, Lufkin shall pay an amount in United States currency equivalent to the Issuing Bank’s actual cost of settlement of its obligation.

(f) Obligations Absolute. Lufkin’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 and each applicable Letter of Credit Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) payment against presentation of any draft or other document presented under a Letter of Credit that proves to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, or which is signed, issued or presented by a Person (or a transferee of such Person) purporting to be a successor or transferee of the beneficiary of such Letter of Credit, (iii) payment by the Issuing Bank or any of its branches or Affiliates being the beneficiary of any Letter of Credit; (iv) any correspondent of the Issuing Bank with respect to a Letter of Credit honoring a drawing under any drawing document up to the amount available under any Letter of Credit even if such drawing document claims an amount in excess of the amount available under such Letter of Credit; (v) the existence of any claim, set-off, defense or other right that Lufkin or any other Person may have at any time against any beneficiary, any assignee of proceeds, the Issuing Bank or any other Person; (vi) the Issuing Bank’s or any correspondent’s having previously paid against fraudulently signed or presented drawing documents (whether or not Lufkin reimbursed the Issuing Bank for such drawing), (vii) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Loan Documents; or (viii) 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 setoff against, Lufkin’s obligations hereunder. Neither the Administrative Agent, the Revolving Lenders or 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 Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to Lufkin to the extent of any direct damages (as opposed to consequential or special, indirect, punitive or exemplary damages, claims in respect of which are hereby waived by Lufkin to the extent permitted by applicable law) suffered by Lufkin that are caused by the Issuing Bank’s failure to exercise care, or for gross negligence or willful misconduct, when determining whether drafts and other documents presented under a Letter of Credit 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 Letter of Credit, the Issuing Bank may, in its sole discretion (but without any obligation to do so), either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank for a Letter of Credit shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under such Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and Lufkin 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 Lufkin 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 Lufkin 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 Lufkin reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if Lufkin fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.14(d) shall apply. Interest accrued pursuant to this paragraph shall be due on demand and shall be for the account of the Issuing Bank with respect to such Letter of Credit, except that interest accrued on and after the date of payment by any Revolving Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Revolving Lender (unless such Revolving Lender is a Defaulting Lender) to the extent of such payment.

(i) Assumption of Risk by Borrower. Subject to paragraph (f) of this Section, as among Lufkin, the Issuing Bank and the Revolving Lenders, Lufkin assumes all risks of the acts and omissions of, or misuse of any of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, subject to the provisions of the applications for the issuance of Letters of Credit, neither the Revolving Lenders, the Issuing Bank, nor the Administrative Agent shall be responsible for:

(i) the validity, sufficiency, accuracy, genuineness, or legal effect of any document submitted by any Person in connection with the application for, and issuance of, and presentation of drafts with respect to, any of the Letters of Credit, even if it should prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent, or forged;

(ii) the validity or sufficiency of any instrument transferring or assigning, or purporting to transfer or assign, any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason;

(iii) the failure of the beneficiary of any Letter of Credit to comply with conditions required in order to draw upon such Letter of Credit, other than those conditions the failure to comply with which is significant and readily apparent on the face of a document submitted in connection with a requested draw under the Letter of Credit;

(iv) errors, omissions, interruptions, or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex, or otherwise, whether or not they be in cipher;

(v) errors in interpretation of technical terms;

(vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any Letter of Credit or of the proceeds thereof;

(vii) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Loan Documents;

(viii) the misapplication by the beneficiary of any Letter of Credit of the proceeds of any drawing under such Letter of Credit; or

(ix) any consequence arising from causes beyond the control of any Revolving Lender, the Administrative Agent or the Issuing Bank, including, without limitation, any act of any Governmental Authority.

(j) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among Lufkin, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Revolving Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, Lufkin shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.13(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 Letters of Credit 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 Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(k) Cash Collateralization. Lufkin shall deposit Cash Collateral in an account with the Administrative Agent in accordance with Section 7.02.

(l) Standards. Each Letter of Credit shall be subject to (A) (i) the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600 (and any subsequent revision thereof approved by a Congress of the International Chamber of Commerce) or (ii) the International Standby Practices 1998, as appropriate, and (B) to the extent required by the laws of the State of New York, the laws of the State of New York. Without in any way limiting any of the foregoing, Lufkin and each Revolving Lender acknowledge that the Issuing Bank shall have no greater responsibility in the operation of the Letters of Credit than is specified in the Uniform Customs and Practice of Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600 or the International Standby Practices 1998, as the case may be.

(m) Increased Costs. If, after the date of this Agreement, as a result of any Change in Law, there shall be imposed, modified or deemed applicable any tax, reserve, special deposit or similar requirement against or with respect to or measured by reference to Letters of Credit issued or to be issued hereunder or participations in such Letters of Credit, and the result shall be to increase the cost to the Issuing Bank or any other Revolving Lender of issuing or maintaining any Letter of Credit or any participation therein, or reduce any amount receivable by the Issuing Bank or any other Revolving Lender hereunder in respect of any Letter of Credit or any participation therein (which increase in cost, or reduction in amount receivable, shall be the result of the reasonable allocation by the Issuing Bank or such other Revolving Lender, as the case may be, of the aggregate of such increases or reductions resulting from such event; the determination of such amount by the Issuing Bank or such other Revolving Lender, as the case may be, shall be conclusive and binding, absent manifest error), then the Issuing Bank or such other Revolving Lender shall notify Lufkin or the Administrative Agent, as the case may be, and upon demand therefor by the Administrative Agent, Lufkin (subject to Section 9.17) shall pay to the Issuing Bank or such other Revolving Lender, from time to time as specified by the Issuing Bank or such other Revolving Lender through the Administrative Agent, such additional amounts as shall be sufficient to compensate the Issuing Bank or such other Revolving Lender for such increased costs or reductions in amount.

(n) Existing Letters of Credit. Prior to the date of this Agreement, Lufkin has caused the letters of credit described on Schedule 2.05(n) (the “Existing Letters of Credit”) to be issued by JPMCB on behalf of Lufkin. The Existing Letters of Credit shall be deemed a utilization of the Revolving Commitments and shall constitute Letters of Credit for all purposes of this Agreement (except the payment of fronting fees pursuant to Section 2.13(b)) and the other Loan Documents, and on the Effective Date JPMCB shall be deemed, without further action by any party to this Agreement, to have sold to each Revolving Lender, and each Revolving Lender shall be deemed, without further action by any party to this Agreement, to have purchased from JPMCB, a participation, to the extent of such Revolving Lender’s Applicable Percentage, in each Existing Letter of Credit and the related LC Exposure.

SECTION 2.6. Funding of Borrowings.

(a) Each 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 Lenders; provided, that Swingline Loans shall be funded as provided in Section 2.04. The Administrative Agent will make such Loans available to Lufkin by promptly crediting the amounts so received, in like funds, to an account of Lufkin maintained with the Administrative Agent in Houston, Texas, and designated by Lufkin in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be remitted by the Administrative Agent to the Issuing Bank. Any deposit to Lufkin’s account by the Administrative Agent in good faith pursuant to a request (whether written or oral) believed by the Administrative Agent to be an authorized request by Lufkin for a Loan hereunder shall be deemed to be a Loan hereunder for all purposes with the same effect as if Lufkin had in fact requested the Administrative Agent to make such Loan.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may (but shall not be required to), in reliance upon such assumption, make available to Lufkin a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, the applicable Lender and the applicable 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 applicable Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such 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 applicable Borrower, the interest rate (including the Applicable Margin) then applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, such amount shall constitute such Lender’s Loan included in such Borrowing.

SECTION 2.7. Interest Elections.

(a) Each Borrowing initially shall be of the Type and Class specified in the applicable Borrowing Request and, if the applicable Borrower has elected a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the applicable Borrower may elect to convert a Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section but subject to the last sentence of Section 2.02(c). The Borrowers 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 Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. Swingline Loans may not be converted.

(b) To make an election pursuant to this Section, the applicable 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 such Borrower were requesting a 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 the form of Exhibit H-1 attached and signed by the applicable Borrower.

(c) 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 thereof, 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, the applicable Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the applicable Class of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If a 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 a Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies Lufkin, then, so long as a Default is continuing (i) no outstanding Borrowing may be converted to or 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 2.8. Termination and Reduction of Commitments.

(a) Unless previously used or terminated, the Term Loan Commitments shall terminate on the date that is sixty (60) days after the Effective Date.

(b) Unless previously terminated, the Revolving Commitments shall terminate on the Maturity Date (except that Letters of Credit issued before that date may remain outstanding in accordance with their terms and the terms of this Agreement).

(c) Lufkin may at any time terminate, or from time to time reduce, the Commitments of either Class; provided that (i) each reduction of the Commitments of a given Class shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000, and (ii) Lufkin shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11 or 2.12, the sum of the Credit Exposures of the applicable Class would exceed the total Commitments of that Class.

(d) Lufkin shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraphs (a) and (b) of this Section at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election, the Class of Commitments to be terminated and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of Loans of the applicable Class of the contents thereof. Each notice delivered by Lufkin pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by Lufkin may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by Lufkin (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 Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders of Loans of the applicable Class in accordance with their respective Commitments of that Class.

(e) The Commitments may not be reinstated after they have been terminated or (except in accordance with Section 2.01(c)) increased after they have been reduced.

SECTION 2.9. Repayment of Loans; Evidence of Debt.

(a) The Borrowers hereby unconditionally promise to pay to the Administrative Agent for the account of each applicable Lender, on the Maturity Date, the aggregate principal amount of all Loans and all LC Disbursements then outstanding, all accrued and unpaid fees under the Loan Documents, all accrued and unpaid interest under the Loan Documents, and all other Obligations accrued and unpaid on such date. Lufkin hereby unconditionally promises to pay to the Administrative Agent for the account of the Issuing Bank, when due, all LC Disbursements which may become due after the Maturity Date, together with all accrued and unpaid fees, all accrued and unpaid interest, and all other Obligations that may accrue under or in connection with this Agreement or any Letter of Credit on or after the Maturity Date. Lufkin hereby unconditionally promises to pay to the Swingline Lender the then-unpaid principal amount of each Swingline Loan on the date such Swingline Loan is due pursuant to Section 2.04.

(b) The principal of the Term Loan shall be due and payable (i) in quarterly installments, the first of which shall be due on the last Business Day of March, 2012, and successive installments to fall due consecutively in their order, one on the last Business Day of each June, September, December and March thereafter, and (ii) in a final installment in the amount of all principal then unpaid, which shall be due on the Maturity Date. The amount of such installments (other than the final installment) shall be:

Payment	Amount of Payment

Each payment due in 2012	$ 4,375,000.00

Each payment due in 2013	$ 6,562,500.00

Each payment due in 2014	$13,125,000.00

Each payment due in 2015	$21,875,000.00

Each payment due in 2016	$21,875,000.00

(c) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers 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.

(d) 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, if any, 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 (or any subset thereof) and each Lender’s share thereof.

(e) The entries made in the accounts maintained pursuant to paragraph (c) or (d) 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 obligations of the Borrowers to repay the principal of and accrued and unpaid interest on Loans in accordance with the terms of this Agreement and the other Loan Documents.

(f) Unless the Administrative Agent shall have received notice from the applicable 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 such Borrower will not make such payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders of Loans of the applicable Class or the Issuing Bank, as the case may be, the amount due. In such event, if such Borrower has not in fact made such payment, each of the Lenders of Loans of the applicable Class 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.

SECTION 2.10. Notes. Upon the request of a Lender, all Loans made by a Lender of each Class shall be evidenced by a single Note of that Class, dated the date of this Agreement (or such appropriate later date if such Lender is a party to an Assignment and Acceptance), executed by Lufkin, payable to the order of such Lender in a principal amount equal to the Commitment of the applicable Class of such Lender as originally in effect and otherwise duly completed. Each Lender is hereby authorized by the Borrower to endorse on the schedule (or a continuation thereof attached to the appropriate Note of such Lender, to the extent applicable) the date, amount, Class and Type of, and the Interest Period (as applicable) for each Loan of that Class made by such Lender to the Borrower and the amount of each payment or prepayment of principal of such Loan received by such Lender; provided that any failure by such Lender to make any such endorsement shall not affect the obligations of either of the Borrowers or any other Loan Party under any Note or this Agreement or any other Loan Document in respect of any such Loan.

SECTION 2.11. Optional Prepayment of Loans.

(a) The Borrowers shall have the right, at any time and from time to time, to prepay any Borrowing in whole or in part, without premium or penalty, subject to prior notice in accordance with paragraph (b) of this Section, on the following terms and conditions: (i) no Eurodollar Borrowing may be prepaid prior to the last day of its Interest Period unless the Borrower shall give notice to the Administrative Agent three (3) Business Days prior to the date of such prepayment and, simultaneously with such prepayment, the applicable Borrower pays to the Administrative Agent for the account of the Lenders of the applicable Class all sums necessary to compensate such Lender, including those costs described in Section 2.17; and (ii) each partial prepayment shall be in an initial aggregate principal amount of $1,000,000 and integral multiples thereof.

(b) The applicable Borrower shall notify the Administrative Agent 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 (1) Business Day before the date of prepayment, and (iii) in the case of prepayment of a Swingline Loan, no later than 11:00 a.m. New York City time on the date of such 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 Commitments as contemplated by Section 2.08, such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.08. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the applicable Class of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Class and 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 and unpaid interest to the extent required by Section 2.14. The applicable Borrower shall reimburse the Administrative Agent on demand for any loss, cost or expense incurred or sustained by any Lender as a result of any such prepayment in accordance with Sections 2.14 and 2.17.

SECTION 2.12. Mandatory Prepayments.

(a) If at any time the aggregate of the Revolving Credit Exposures exceeds the total of the Revolving Commitments, Lufkin shall immediately pay to the Administrative Agent for the benefit of the Revolving Lenders the principal amount of any Revolving Loans and Swingline Loans then outstanding to the extent that (a) the aggregate Revolving Credit Exposures at such time exceed (b) the total of the Revolving Commitments at such time. Accrued and unpaid interest on the amount of the Loans so prepaid shall be due and payable at the time of such prepayment. If no Revolving Borrowings are outstanding and only LC Exposures remain, Lufkin shall deposit Cash Collateral in an account with the Administrative Agent pursuant to Section 7.02 in an aggregate amount equal to such excess.

(b) On or before each date which is three Business Days after the earlier of (i) the date on which the financial statements of the Borrower referred to in Section 5.01(a) or Section 5.01(b) for the fiscal quarter of the Borrower with respect to which such prepayment is made are required to be delivered to the Administrative Agent for delivery to the Lenders and (ii) the date such financial statements are actually delivered to the Administrative Agent (commencing with the fiscal quarter ending on March 31, 2012), the Term Loans shall be reduced on a pro rata basis according to the outstanding principal balance of the Term Loans by (x) when the most recently determined Leverage Ratio is greater than 2.00 to 1.00, an amount equal to fifty percent (50%) of Excess Cash Flow for the four consecutive fiscal quarters then most recently ended, and (y) when the most recently determined Leverage Ratio is equal to or less than 2.00 to 1.00 but equal to or greater than 1.50 to 1.00, an amount equal to twenty-five percent (25%) of Excess Cash Flow for the four consecutive fiscal quarters then most recently ended. No prepayment shall be required when the most recently determined Leverage Ratio is less than 1.50 to 1.00.

(c) The Term Loans shall be reduced on a pro rata basis according to the outstanding principal balance of the Term Loans by

	(i)	an amount equal to 100% of the Net Cash Proceeds of all Asset Sales received by a Borrower or any of its consolidated Subsidiaries and not reinvested within 180 days after receipt; and
	(ii)	an amount equal to 100% of the Net Cash Proceeds in connection with any issuance or sale of debt securities, preferred Equity Interests or instruments or incurrence of loans, in each case by a Borrower or any of its consolidated Subsidiaries, in each case upon receipt thereof by the applicable Borrower or such consolidated Subsidiary; and
	(iii)	an amount equal to fifty percent (50%) of the Net Cash Proceeds of all issuances of Equity Interests (other than preferred Equity Interests) by Lufkin or any of its consolidated Subsidiaries; provided, that in the case of such an issuance in connection with an acquisition by Lufkin or any of its consolidated Subsidiaries of Equity Interests in, or assets of, another Person, prepayment shall be required only of an amount equal to 50% of the Net Cash Proceeds remaining after application of such Net Cash Proceeds to such acquisition.

(d) The Term Loans shall be reduced on a pro rata basis according to the outstanding principal balance of the Term Loans by an amount equal to 100% of the proceeds of insurance received by either of the Borrowers or any of their respective consolidated Subsidiaries on account of the damage, destruction or loss of any Property and not reinvested in similar Property within 180 days after receipt.

(e) Payments of Term Loans pursuant to clause (b), (c) or (d) above shall be subject to Section 2.22 and shall be applied to the installments on the Term Loans in inverse order of their maturities.

(f) If the Acquisition is not consummated on or before December 30, 2011, the Borrowers shall repay all Term Loans on such day.

SECTION 2.13. Fees.

(a) Lufkin shall pay to the Administrative Agent for the ratable account of each Lender (other than a Defaulting Lender) a commitment fee (the “Unused Commitment Fee”) (which fee shall accrue at the applicable Unused Commitment Fee Rate determined in accordance with the definition of Applicable Margin) on the average daily Unused Commitment of each Class of such Lender during the period from and including the date such Commitment arises to but excluding the date on which such Commitment terminates. Accrued and unpaid Unused Commitment Fees shall be due in arrears (i) with respect to the Term Loans, on the Term Loan Borrowing Date (if not the Effective Date) and (ii) on the last Business Day of March, June, September and December, beginning March 2012, and on the date on which the Commitments of the respective Classes terminate, commencing on the first such date to occur after the date hereof. Subject to Section 9.17, all Unused Commitment 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) Lufkin shall pay (i) to the Administrative Agent for the ratable account of each Revolving Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue on each day at the rate of the Applicable Margin from time to time in effect for Eurodollar Borrowings on the amount of such Lender’s LC Exposure on such day (excluding any portion thereof attributable to unreimbursed LC Disbursements) on each day during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Commitment terminates and the date on which such Revolving Lender ceases to have any LC Exposure; provided, however, that in no event shall the aggregate participation fees payable to all Lenders in any one year period be less than $500, and (ii) to the Issuing Bank for its own account a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the aggregate LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Revolving Commitments and the date on which there ceases to be any LC Exposure under such Letter of Credit, as well as the Issuing Bank’s standard fees with respect to the administration, issuance, amendment, payment, negotiation, renewal or extension of any Letter of Credit or processing of drawings thereunder. Accrued and unpaid participation fees and fronting fees for each Letter of Credit shall be due in arrears on the last Business Day of each March, June, September and December, beginning March 31, 2012; provided that all such accrued and unpaid fees shall be due on the date on which the Revolving Commitments terminate and all such fees accruing after the date on which the Revolving Commitments terminate shall be due on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be due within ten (10) days after demand. All participation fees and fronting 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) Lufkin shall pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between Lufkin and the Administrative Agent.

(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 Unused Commitment Fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

SECTION 2.14. Interest.

(a) The Loans comprising each ABR Borrowing shall bear interest at a rate per annum equal to the lesser of (i) the Alternate Base Rate from time to time in effect plus the Applicable Margin from time to time in effect for ABR Borrowings and (ii) the Highest Lawful Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the lesser of (i) the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin from time to time in effect for Eurodollar Borrowings and (ii) the Highest Lawful Rate.

(c) Swingline Loans shall bear interest at a rate per annum equal to the lesser of (i) the Alternate Base Rate from time to time in effect plus the Applicable Margin from time to time in effect and (ii) the Highest Lawful Rate.

(d) Notwithstanding the foregoing, but subject to Section 9.17, if any principal of or interest on any Loan or any LC Disbursement or any fee or other amount payable by a 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, not to exceed the Highest Lawful Rate, or (ii) in the case of any other amount, at the Default Rate, not to exceed the Highest Lawful Rate.

(e) Accrued and unpaid interest on each Loan shall be due in arrears on each Interest Payment Date for such Loan and upon the termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be due on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a payment of an ABR Loan prior to the end of the Availability Period), accrued and unpaid interest on the principal amount repaid or prepaid shall be due 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 and unpaid interest on such Loan shall be due on the effective date of such conversion.

(f) 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 or Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.15. Alternate Rate of Interest. If, prior to the commencement of any Interest Period for a Eurodollar Borrowing, the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (a) Dollar deposits are not being offered to banks in the London interbank dollar market for the amount and Interest Period of such Eurodollar Borrowing or (b) adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period, or if 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, the Administrative Agent shall give notice thereof to Lufkin and the Lenders by telephone or telecopy as promptly as practicable thereafter, and, until the Administrative Agent notifies Lufkin 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.

SECTION 2.16. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets or with respect to or measured by reference to assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or the Issuing Bank or the London interbank dollar market any other condition, cost or expense (other than Taxes) affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Eurodollar Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Lender, the Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then subject to Section 9.17, upon request of such Lender, Issuing Bank or other Recipient, the Borrower will pay to such Lender, Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Issuing Bank or other Recipient, as the case may be, within thirty (30) days after demand therefor, such additional costs incurred or reduction suffered.

(b) If any Lender or Issuing Bank determines that any Change in Law affecting such Lender or Issuing Bank or any lending office of such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit 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 Issuing Bank’s policies and the policies of such Lender’s or Issuing Bank’s holding company with respect to capital adequacy), then from time to time subject to Section 9.17, 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 Lufkin and shall be conclusive absent manifest error. The applicable Borrower shall pay such Lender or 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 Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or the Issuing Bank, as the case may be, notifies Lufkin 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 (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

SECTION 2.17. 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 2.08(d) 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 2.21, then, in any such event, subject to Section 9.17, the Borrower shall compensate each Lender of the applicable Class 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 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 London interbank dollar 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 Lufkin and shall be conclusive absent manifest error. The applicable Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

SECTION 2.18. Taxes.

(a) For purposes of this Section, the term “Lender” includes the Issuing Bank.

(b) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c) The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d) The Loan Parties shall jointly and severally indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified 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 Lufkin by a Lender or the Issuing Bank (with a copy to the Administrative Agent), 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.

(e) Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.04(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such 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 any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f) As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section, such Loan Party 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.

(g) (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Lufkin and the Administrative Agent, at the time or times reasonably requested by Lufkin or the Administrative Agent, such properly completed and executed documentation reasonably requested by Lufkin the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Lufkin or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Lufkin or the Administrative Agent as will enable Lufkin or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(ii) Without limiting the generality of the foregoing, in the event that a Borrower is a U.S. Borrower,

(A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(i) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii) executed originals of IRS Form W-8ECI;

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit L to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of either Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit L on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h) If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.18 (including by the payment of additional amounts pursuant to this Section 2.18), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.18 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. This paragraph (h) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) Each party’s obligations under this Section 2.18 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

SECTION 2.19. Illegality. If at any time any Lender determines that any Change in Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for such Lender to make, maintain or fund Eurodollar Loans, or materially restricts the authority of such Lender to purchase or sell, or to take deposits of, the London interbank dollar market, or to determine or charge interest rates based upon the Adjusted LIBO Rate, then, on notice thereof by such Lender (through the Administrative Agent) to Lufkin, any obligation of such Lender to make or continue Eurodollar Loans or to convert ABR Loans to Eurodollar Loans shall be suspended until such Lender (through the Administrative Agent) notifies Lufkin that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrowers shall, upon demand from such Lender (through the Administrative Agent), prepay or, if applicable, convert all Eurodollar Loans to ABR Loans, either on the last day of the Interest Period thereof, if such Lender may lawfully continue to maintain such Eurodollar Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Loans. Upon any such prepayment or conversion, the Borrowers shall also pay interest on the amount so prepaid or converted. If a Lender gives a notice under this Section 2.19, such Lender shall, upon the request of the Borrowers, 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 sole judgment of such Lender, such designation (i) would eliminate the need for such notice and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrowers hereby jointly and severally agree to pay all reasonable costs and expenses incurred by such Lender in connection with any such designation.

SECTION 2.20. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrowers shall make each payment required to be made by them hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.16, 2.17 or 2.18, or otherwise) prior to 12:00 noon New York City time on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date 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 its offices at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, except payments to be made directly to the Issuing Bank as expressly provided herein and payments pursuant to Sections 2.16, 2.17, 2.18 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, except with respect to Defaulting Lenders. 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 (unless, in the case of Eurodollar Borrowings, the result of such extension of time would be to extend the date of such payment into another calendar month (in the case of a Eurodollar Loan) or (in the case of any Loan) beyond the scheduled Maturity Date, and in either such event such payment shall be due on the Business Day immediately preceding the day on which such payment would otherwise have been due), and, in the case of any payment accruing interest, interest thereon shall be due 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 Obligations then due hereunder, any amounts received on account of the Obligations shall, subject to the provisions of Sections 2.05 and 2.22, such funds shall be applied by the Administrative Agent as provided in Section 7.03.

(c) Except to the extent otherwise provided herein, (i) each Borrowing from the Lenders, each payment of Unused Commitment Fees and other fees and each termination or reduction of the Commitments shall be made pro rata according to the respective Applicable Percentages of the Lenders of Loans of the applicable Class; and (ii) each payment by the Borrowers of principal of or interest on Loans of a particular Class shall be made to the Administrative Agent for the account of the Lenders of such Class pro rata according to the Lenders’ respective Commitments.

(d) 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 other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; 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 (x) any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) 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 Borrowers or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

Each Loan Party 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 each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation.

(e) Unless the Administrative Agent shall have received notice from Lufkin 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 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, 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.

(f) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(c), Section 2.05(d) or (e), 2.06(b) or 2.20(e), the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), (i) 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, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under such Sections; in the case of each of clauses (i) and (ii)above, in any order as determined by the Administrative Agent in its discretion.

SECTION 2.21. Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.16, or requires either Borrower to pay any Indemnified Taxes or additional amounts to any Lender or to any Governmental Authority for the account of any Lender pursuant to Section 2.18, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Loans or Letters of Credit 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 Section 2.16 or 2.18, 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 Borrowers hereby jointly and severally agree 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 2.16, or if the Borrowers are required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 2.21(a), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, 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 (other than its existing rights to payments pursuant to Section 2.16 or Section 2.18) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may, but need not, be another Lender, if a Lender accepts such assignment); provided that (i) Lufkin shall have paid to the Administrative Agent the assignment fee, (if any) specified in Section 9.04; (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, all accrued and unpaid interest thereon, all accrued and unpaid fees and all other amounts due to it hereunder and other the other Loan Documents (including any amounts under Section 2.17)from the assignee (to the extent of such outstanding principal and accrued interest and fees) or a Borrower (in the case of all other amounts); (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.16 or payments required to be made pursuant to Section 2.18, such assignment will result in a reduction in such compensation or payments; (iv) such assignment does not conflict with applicable law; and (v) in the case of any assignment resulting from a Lender’s becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent. 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.

SECTION 2.22. Defaulting Lenders.

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article 7 or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 2.20(d) shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Bank or Swingline Lender hereunder; third, to Cash Collateralize the Issuing Bank’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.22(a)(v); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the Issuing Bank’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.22(a)(v); sixth, to the payment of any amounts owing to the Lenders, the Issuing Bank or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Bank or Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Disbursements in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 4.03 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and LC Disbursements owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Disbursements owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in LC Exposures and Swingline Loans are held by the Lenders pro rata in accordance with the Commitments of the applicable Class without giving effect to Section 2.22(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.22(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. (A) No Defaulting Lender shall be entitled to receive any Unused Commitment Fee for any period during which that Lender is a Defaulting Lender (and neither Borrower shall be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(A) Each Defaulting Lender shall be entitled to receive fees pursuant to Section 2.13(b) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.22(a)(v).

(B) With respect to any Unused Commitment Fee or fee pursuant to Section 2.13(b) not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrowers shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in LC Exposures or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Bank and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Bank’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(1) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in LC Exposures and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 4.03 are satisfied at the time of such reallocation (and, unless Lufkin shall have otherwise notified the Administrative Agent at such time, the Borrowers shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Revolving Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(i) Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, Lufkin shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and (y) second, Cash Collateralize the Issuing Bank’s Fronting Exposure in an amount not less than the Minimum Collateral Amount accordance with the procedures set forth in Section 7.02.

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and the Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Commitments of the applicable Class (without giving effect to Section 2.22(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) New Swingline Loans/Letters of Credit. So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

ARTICLE 3 - Representations and Warranties

The Borrowers jointly and severally represent and warrant to the Administrative Agent, the Issuing Bank, and each Lender that:

SECTION 3.1. Organization; Powers. Lufkin and each of its consolidated Subsidiaries and each Loan Party are duly organized, validly existing and in good standing under the laws of the jurisdiction of their respective formation or organization, have all requisite power and authority and all Licenses to carry on their respective businesses 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, are qualified to do business in, and are in good standing in, every jurisdiction where such qualification is required.

SECTION 3.2. Authorization; Enforceability. The Transactions are within the organizational power and authority of each Borrower and each other Loan Party and have been duly authorized by all necessary corporate, limited liability company, partnership or other organizational action (and, if required, stockholder, member, manager, or partner action), on the part of the Borrowers and each other Loan Party. This Agreement and the other Loan Documents to be executed and delivered at or before such time, have been duly executed and delivered by the Borrowers and each other Loan Party, as applicable, and constitute legal, valid and binding obligations of the Borrowers and each other Loan Party, as applicable, enforceable in accordance with their respective terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar 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 3.3. Governmental Authorizations; 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 or any other Person, except such as have been obtained or made and are in full force and effect, (b) do not and will not violate any applicable Law or the Organizational Documents of either of the Borrowers or any other Loan Party or any order of any Governmental Authority, (c) do not and will not violate or result in a default under any Contractual Obligation binding upon either of the Borrowers or any of their respective consolidated Subsidiaries or any other Loan Party, or any of their respective assets, or give rise to a right thereunder to require any payment to be made by either of the Borrowers or any of Lufkin’s consolidated Subsidiaries or any other Loan Party, and (d) except for the Liens created by the Loan Documents, do not and will not result in the creation or imposition of any Lien on any asset of either of the Borrowers or any of Lufkin’s consolidated Subsidiaries or any other Loan Party.

SECTION 3.4. Financial Condition; No Material Adverse Change.

Each notice delivered under this Section shall be accompanied by a statement of an Authorized Officer of Lufkin setting forth the details of the event or development requiring such notice and any action taken or proposed to be taken with respect thereto.

SECTION 5.3. Existence; Conduct of Business. Lufkin will, and will cause each of its consolidated Subsidiaries to, do or cause to be done all things necessary to preserve, renew and keep in full force and effect its legal existence and the rights, Licenses, permits, Intellectual Property, privileges and franchises material to the conduct of its business; provided that the foregoing shall not prohibit any merger, consolidation, liquidation or dissolution permitted under Section 6.03.

SECTION 5.4. Payment of Obligations. Lufkin will, and will cause each of its consolidated Subsidiaries to, pay its obligations, including Tax liabilities, that, if not paid, could reasonably be expected to result in a Material Adverse Effect before the same shall become delinquent or in default, except where (a) the validity or amount thereof is being contested in good faith by appropriate proceedings, (b) Lufkin or such consolidated Subsidiary has set aside on its books adequate reserves with respect thereto in accordance with GAAP, and (c) the failure to make payment pending such contest could not reasonably be expected to result in a Material Adverse Effect. Lufkin will, and will cause each of its consolidated Subsidiaries to, comply with all of their respective Contractual Obligations, except for instances of noncompliance that could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

SECTION 5.5. Maintenance of Properties. Lufkin will, and will cause each of its consolidated Subsidiaries to, keep and maintain all Property material to the conduct of its business in good working order and condition, ordinary wear and tear excepted, and make all replacements and additions to its Property material to its business as may be reasonably necessary to conduct its business in the manner heretofore conducted.

SECTION 5.6. Insurance. In addition to the insurance requirements set forth in the Security Documents, Lufkin will, and will cause each of its consolidated Subsidiaries to, keep insured by financially sound and reputable insurers all Property of a character usually insured by responsible entities engaged in the same or similar business similarly situated against loss or damage of the kinds and in the amounts customarily insured against by such entities and carry such other insurance as is usually carried by such entities (which may, to the extent such entities are self-insured against certain risks, include self-insurance); provided, however, that in any event Lufkin and its consolidated Subsidiaries will maintain (subject to the preceding self-insurance provisions):

(i) Property Insurance. Insurance against loss or damage covering substantially all of the tangible real and personal Property of such Person by reason of any Peril (as defined below) in such amounts as shall be reasonable and customary and sufficient to avoid the insured named therein from becoming a co-insurer of any loss under such policy, but in any event in such amounts as are reasonably available as determined by Lufkin’s independent insurance broker.

(ii) Automobile Liability Insurance for Bodily Injury and Property Damage. Insurance in respect of all vehicles (whether owned, hired or rented by such Person) at any time located at, or used in connection with, its Properties or operations against liabilities for bodily injury and Property damage in such amounts as are then customary for vehicles used in connection with similar Properties and businesses, but in any event to the extent required by applicable law.

(iii) Comprehensive General Liability Insurance. Insurance against claims for bodily injury, death, or Property damage occurring on, in or about the real property of such Person, in such amounts as are then customary for Property similar in use in the jurisdictions where such Properties are located.

(iv) Workers’ Compensation Insurance. Workers’ compensation insurance (including employers’ liability insurance) to the extent required by applicable law, which may be self-insurance to the extent permitted by applicable law.

(v) Business Interruption Insurance. Business interruption insurance in such amounts as may be recommended from time to time by Lufkin’s independent insurance broker.

All insurance shall be written by financially responsible companies selected by Lufkin and its Subsidiaries reasonably acceptable to the Administrative Agent. For purposes hereof, the term “Peril” shall mean, collectively, fire, lightning, flood, windstorm, hail, explosion, riot and civil commotion, vandalism and malicious mischief, damage from aircraft, vehicles, and smoke, and other perils covered by the “all-risk” endorsement then in use in the jurisdictions where the Properties of Lufkin and its Subsidiaries, as the case may be, are located.

SECTION 5.7. Books and Records; Inspection Rights. Lufkin will, and will cause each of its consolidated Subsidiaries to, keep proper books of record and account in which full, true and correct entries are made of all dealings and transactions in relation to its business and activities. Lufkin will, and will cause each of its consolidated Subsidiaries to, permit any representatives designated by the Administrative Agent or any Lender, upon reasonable prior notice, (i) to visit and inspect its properties, (ii) to examine and make extracts from its books and records, and (iii) to discuss its affairs, finances and condition with its officers and independent accountants, in each case at such reasonable times and as often as reasonably requested.

SECTION 5.8. Compliance with Laws. Lufkin will, and will cause each of its consolidated Subsidiaries to, comply with all Laws, including all Environmental Laws, rules, regulations and orders of any Governmental Authority applicable to 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.

SECTION 5.9. Further Assurances. Each Borrower will execute and deliver, and will cause each of its consolidated Subsidiaries to execute and deliver, such further agreements, documents, and instruments and take such further actions as may be requested by the Administrative Agent to carry out the terms and provisions and purposes of this Agreement and the other Loan Documents and to evidence the Obligations. Without limiting the generality of the foregoing, each Borrower will take all necessary actions to and otherwise ensure that, at all times, the Obligations will rank at least pari passu in respect of priority of treatment with all other present and future Indebtedness of such Borrower (excluding rights of secured parties with respect to Permitted Encumbrances).

SECTION 5.10. ERISA; Canadian Pension Plans and Canadian Benefit Plans. Lufkin will, and will cause each of its consolidated Subsidiaries and each ERISA Affiliate to, comply with all minimum funding requirements and all other material requirements of ERISA so as not to give rise to any liability thereunder. The Borrowers and their consolidated Subsidiaries will maintain or cause to be maintained each Canadian Pension Plan, should such as plan ever be in effect, and each Canadian Benefit Plan in compliance with its terms and in compliance with the requirements of any and all applicable Laws and in good standing with applicable regulatory authorities. All obligations of the Borrowers, and each of their respective Subsidiaries under each Canadian Pension Plan and Canadian Benefit Plan will be performed in accordance with the terms thereof and any requirement of applicable Law (including, without limitation, the Income Tax Act (Canada) and the Supplemental Pension Plan Act (Quebec)), except where the failure to so perform would not reasonably be expected to result in a Material Adverse Effect. Neither the Borrowers nor any of their respective Subsidiaries will incur any material obligation in connection with the termination of or withdrawal from any Canadian Pension Plan or Canadian Benefit Plan or permit any Canadian Pension Plan to have any unfunded liabilities on an actuarial basis which would reasonably be expected to have a Material Adverse Effect.

SECTION 5.11. Delivery of Certain Amendments and Funded Debt Documents. Lufkin will, and will cause each of its consolidated Subsidiaries to, promptly deliver to the Administrative Agent any amendment, modification, or supplement to (a) the certificate or articles of incorporation, articles of organization, bylaws, regulations, or other Organizational Documents of Lufkin or any such Subsidiary, and (b) any agreement, document, or instrument entered into by Lufkin or any such Subsidiary in connection with any Funded Debt. Lufkin will, and will cause each of its consolidated Subsidiaries to, deliver to the Administrative Agent, promptly after any agreement, document, or instrument entered into by Lufkin or any such Subsidiary evidencing any Funded Debt comes into existence, a true and correct copy of each such agreement, document, or instrument.

SECTION 5.12. Use of Proceeds and Letters of Credit. The Borrowers will use the proceeds of the Loans only to provide financing for the Acquisition, to refinance existing indebtedness and finance the ongoing working capital and general corporate requirements of Lufkin and its consolidated Subsidiaries in the ordinary course of business, including the issuance of Letters of Credit, and not for any purpose that would violate any Law. No part of the proceeds of any Loan (and no Letter of Credit) will be used, whether directly or indirectly, to purchase or carry any margin stock (as such term is used in Regulation U of the Board), to repay or otherwise refinance indebtedness of Lufkin or any Subsidiary incurred to purchase or carry any margin stock, to extend credit for the purpose of purchasing or carrying any margin stock, or for any other purpose which would make any extension of credit in connection with this Agreement a “purpose credit” within the meaning of Regulation U of the Board, or for any purpose that entails a violation of any of the Regulations of the Board, including Regulations T, U and X. All Loans and Letters of Credit will be used for business, commercial, investment, agricultural or other similar purposes and not for personal, family or household use.

SECTION 5.13. Certain Changes. Lufkin will, and will cause each of its Subsidiaries to, notify the Administrative Agent no later than the date on which either Borrower or any other Loan Party changes its jurisdiction of formation or organization, its name, the location of its chief executive office or principal place of business, or the place where it keeps its books and records. Lufkin will notify the Administrative Agent no later than the date on which Lufkin or any of its consolidated Subsidiaries creates or acquires any Subsidiary.

(b) Agreement to Deliver Security Documents. Within thirty (30) days after the creation or any acquisition by Lufkin or any of its Subsidiaries of any Material Domestic Subsidiary, or after an existing Subsidiary becomes a Material Domestic Subsidiary, Lufkin shall cause such Material Domestic Subsidiary to execute and deliver to the Administrative Agent on behalf of the Lenders one or more Security Documents granting to the Administrative Agent on behalf of the Lenders a first priority security interest upon and covering substantially all of the Property of such Material Domestic Subsidiary to secure all Obligations then or thereafter existing or arising, to the end that all Material Domestic Subsidiaries shall at all times have granted a Lien in all their assets (other than Excluded Assets) to secure such Obligations.

(c) Agreement to Deliver Pledge Agreements. Within thirty (30) Business Days after the creation or any acquisition by Lufkin or any of its Subsidiaries of a Material Domestic Subsidiary or a First-Tier Foreign Subsidiary, or after an existing Subsidiary becomes a Material Domestic Subsidiary or First-Tier Foreign Subsidiary, Lufkin shall execute and deliver, and cause the owner or owners of all of the Equity Interests (or, in the case of a Material Subsidiary that is a First-Tier Foreign Subsidiary, the owner or owners of not less than 65% of the Equity Interests) in such Material Subsidiary to execute and deliver, a Pledge Agreement, duly authorized and executed by Lufkin and each such other owner or owners, together with any certificates evidencing such Equity Interests, and all necessary consents and approvals, to the end that all of the Equity Interests and related Property (or, in the case of a Material Foreign Subsidiary, not less than 65% of the Equity Interests and related Property) in all Material Subsidiaries (other than Material Subsidiaries that are not First-Tier Foreign Subsidiaries) shall at all times secure all Obligations then or thereafter existing or arising. In connection therewith, Lufkin shall deliver, and shall cause each such owner or owners and each such Material Subsidiary to deliver, to the Administrative Agent with respect to such Material Subsidiary all of the materials described in clauses (n) and (o) of Section 4.01, evidence that each Material Domestic Subsidiary executing and delivering a Pledge Agreement pursuant to this Section has received good and adequate consideration for doing so, and all other such agreements, documents, instruments and other writings as may be necessary or desirable (in the opinion of the Administrative Agent) to create and perfect a valid first Lien on, pledge of and security interest in all such Equity Interests and related property and evidence satisfactory to the Administrative Agent that the entity granting such security interest has taken all corporate and other organizational action and obtained all consents necessary to approve and authorize its execution and delivery of such Pledge Agreement and the performance of its obligations thereunder and, if requested by the Administrative Agent, an opinion of counsel in form, scope and substance reasonably acceptable to the Administrative Agent.

(d) Perfection and Protection of Security Interests and Liens. In addition and not by way of limitation of the foregoing, Lufkin will from time to time deliver, and cause each Loan Party to deliver, to the Administrative Agent any and all financing statements, continuation statements, extension agreements, certificates, and other documents, properly completed (and executed and acknowledged when required) by the appropriate Person, in form and substance satisfactory to the Administrative Agent, which the Administrative Agent may in its discretion request for the purpose of perfecting, confirming, or protecting any Liens or other rights in any Collateral at any time securing any Obligations. In addition to the foregoing, each of the Borrowers hereby authorizes, and shall cause each Loan Party to authorize, the Administrative Agent to file in the appropriate filing office pursuant to applicable Law such financing statements, assignments and continuation statements as the Administrative Agent shall deem necessary or desirable for the purpose of perfecting, confirming, or protecting any Liens or other rights in the Collateral without the signature of either of the Borrowers or any other Loan Party.

(e) Consideration. It is agreed and understood that the agreement of Lufkin under this Section 5.14 to cause each Material Domestic Subsidiary to execute and deliver a Guaranty Agreement and a Security Agreement and to cause the Equity Interest of each Material Domestic Subsidiary or First-Tier Foreign Subsidiary to be pledged as security for the Obligations (to the extent herein set forth) is a condition precedent to the making of the Loans and the issuance of Letters of Credit pursuant to this Agreement, and that the entry into this Agreement by the Lenders constitutes good and adequate consideration therefor.

If the Borrowers are required to provide an amount of Cash Collateral hereunder solely 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 Borrowers within three (3) Business Days after all Events of Default have been cured or waived, free of any Lien or other interest in favor of the Administrative Agent, any Lender or the Issuing Bank. The rights of the Administrative Agent and the Lenders under this Section 7.02 may be exercised from time to time and at all such times as the conditions precedent thereto may exist.

SECTION 7.3. Application of Funds. After the exercise of remedies provided for in Section 7.02 (or after the Loans have automatically become immediately due and payable and the LC Exposures have automatically been required to be Cash Collateralized as set forth in Section 7.02), or if at any time insufficient funds are received by and available to the Administrative Agent to pay fully all Obligations then due hereunder, any amounts received on account of the Obligations shall, subject to the provisions of Sections 2.05 and 2.22, be applied by the Administrative Agent in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees, charges and disbursements of counsel to the Administrative Agent and amounts payable under Sections 2.16, 2.17, 2.18, and 2.19 hereof) payable to the Administrative Agent in its capacity as such;

Second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal, interest, Letter of Credit fees and Unused Commitment Fees) payable to the Lenders and the Issuing Bank (including fees, charges and disbursements of counsel to the respective Lenders and the Issuing Bank and amounts payable under Sections 2.16, 2.17, 2.18 and 2.19 hereof, ratably among them in proportion to the respective amounts described in this clause Second payable to them;

Sixth, the balance, if any, after all Obligations have been indefeasibly paid in full, to Lufkin, or as otherwise required by Law.

Subject to Sections 2.05(d), (e) and (k) and Section 7.02, amounts used to Cash Collateralize the aggregate LC Exposures pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have been either fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above.

Notwithstanding the foregoing, Obligations arising under Swap Agreements and Hedge Agreements shall be excluded from the application described above if the Administrative Agent has not received written notice thereof, together with such supporting documentation as the Administrative Agent may reasonably request, from the applicable swap or hedge agreement obligee.

SECTION 7.4. Remedies Cumulative. All rights and remedies given by this Agreement and the other Loan Documents are cumulative and not exclusive of any of such rights or remedies or of any other rights or remedies now or hereafter existing at Law, in equity or otherwise, available to the Administrative Agent, the Issuing Bank or any Lender, and no course of dealing, and no delay or omission in exercising any right or remedy, shall operate as a waiver of any right or remedy, and every right and remedy may be exercised from time to time and as often as shall be deemed appropriate by the Administrative Agent, the Issuing Bank or any other Lender.

SECTION 7.5. Performance by the Administrative Agent, Etc. If either of the Borrowers or any other Loan Party shall fail to perform any covenant or agreement in accordance with the terms of the Loan Documents, the Administrative Agent may (but shall not be obligated to) perform or attempt to perform, or may (but shall not be obligated to) cause any Lender (with the consent of such Lender) to perform or attempt to perform, such covenant or agreement on behalf of such Borrower or such Loan Party. In such event, the Borrowers shall, at the request of the Administrative Agent, promptly pay any amount expended by the Administrative Agent or the Lenders in connection with such performance or attempted performance to the Administrative Agent, together with interest thereon at the Default Rate from and including the date of such expenditure to but excluding the date such expenditure is paid in full. Notwithstanding the foregoing, it is expressly agreed that neither the Administrative Agent nor any Lender shall have any liability or responsibility for the performance of any obligation of either of the Borrowers or any other Person under this Agreement or any of the other Loan Documents.

ARTICLE 8 - Agency

SECTION 8.1. Appointment and Authority. Each of the Lenders and the Issuing Bank hereby irrevocably appoints JPMCB to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents 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 or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Bank, and neither of the Borrowers nor any other Loan Party shall have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom and is intended to create or reflect only an administrative relationship between contracting parties. The Administrative Agent is hereby expressly authorized on behalf of the other Lenders:

(a) to receive on behalf of each of the other Lenders any payment of principal of or interest on the Loans outstanding hereunder and all other amounts accrued hereunder paid to the Administrative Agent, and promptly to distribute to each other Lender its proper share of all payments so received;

(b) to give notice within a reasonable time on behalf of each other Lender to the Borrowers of any Default of which the Administrative Agent has actual knowledge as provided in Section 8.03(b);

(c) to distribute to the other Lenders copies of all notices, agreements and other material as provided for in this Agreement as received by the Administrative Agent; and

(d) to distribute to the Borrowers or other Loan Party any and all requests, demands and approvals received by the Administrative Agent from any other Lender or the Issuing Bank. Nothing herein contained shall be construed to constitute the Administrative Agent as a trustee for any holder of the promissory notes or of a participation therein, nor to impose on the Administrative Agent any duties or obligations other than those expressly provided for in the Loan Documents; and

(e) subject to Section 9.02, to execute, deliver and accept on behalf of the Lenders the Assumption Agreement and all other Loan Documents.

SECTION 8.2. Rights as a Lender. The Person 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 the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, either of the Borrowers or any Subsidiary or other Affiliate of either of the Borrowers as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

SECTION 8.3. Exculpatory Provisions.

(a) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to either of the Borrowers or any of their respective Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary under the circumstances), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent in writing by Lufkin, a Lender or an Issuing Bank.

(c) 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 or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article 4 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

SECTION 8.4. Reliance by Administrative Agent. 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 (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated 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 have been made by the proper Person and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan or the issuance, extension, renewal or increase of a Letter of Credit that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Bank prior to the making of such Loan or the issuance, extension, renewal or increase of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for either 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 8.5. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document 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 of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article 8 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 Commitments as well as to their activities as sub-agents of or Related Parties to Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

SECTION 8.6. Resignation of Administrative Agent.

(a) The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Bank and Lufkin. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, with the approval of Lufkin (so long as no Default has occurred and is continuing), to appoint a successor, which shall be a bank with an office in New York City or an Affiliate of any such bank with an office in New York City. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b) If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable law, by notice in writing to Lufkin and such Persons, remove such Person as Administrative Agent and, with the approval of Lufkin (so long as no Default has occurred and is continuing), appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any Collateral held by the Administrative Agent on behalf of the Lenders or the Issuing Bank under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such Collateral until such time as a successor Administrative Agent is appointed) and (2) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the Issuing Bank directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring or removed 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 the retiring or removed Administrative Agent was acting as Administrative Agent.

SECTION 8.7. Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties 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 and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties 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 other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 8.8. No Other Duties, etc. Anything herein to the contrary notwithstanding, neither the Sole Bookrunner, any Joint Lead Arranger, any Co-Syndication Agent or the Documentation Agent shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the Issuing Bank hereunder.

SECTION 8.9. Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any other Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or LC Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on either Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, LC Exposures and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Bank and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Bank and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Bank and the Administrative Agent under Sections 2.13 and 9.03) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the Issuing Bank, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 2.13 or 9.03.

Nothing in this Section 8.09 shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the Issuing Bank any plan of reorganization, arrangement, adjustment, or composition affecting the Obligations or the rights of any Lender or the Issuing Bank to authorize the Administrative Agent to vote in respect of the claim of any Lender or the Issuing Bank in any such proceeding.

SECTION 8.10. Collateral and Guaranty Matters.

(a) The Secured Parties irrevocably authorize the Administrative Agent, at its option and in its discretion,

(i) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (x) upon termination of all Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Administrative Agent and the Issuing Bank shall have been made), (y) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other Disposition permitted under the Loan Documents, or (z) subject to Section 9.02, if approved, authorized or ratified in writing by the Required Lenders; and

(ii) to release any Material Domestic Subsidiary from its obligations under any Guaranty or any Security Document as permitted by Section 9.18.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release its interest in particular types or items of property, or to release any Material Domestic Subsidiary from its obligations under any Guaranty or any Security Document pursuant to this Section 8.10.

(b) The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any other Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

SECTION 8.11. Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrowers), ratably according to their respective Applicable Percentages, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents, provided, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Person’s gross negligence or willful misconduct. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE ADMINISTRATIVE AGENT SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OR STRICT LIABILITY OF SUCH PERSON. The Administrative Agent shall not be required to do any act hereunder or under any other document or instrument delivered hereunder or in connection herewith or take any action toward the execution or enforcement of the agencies hereby created, or to prosecute or defend any suit in respect of this Agreement or the Loan Documents or any collateral security, unless indemnified to its satisfaction by the Lenders against loss, cost, liability, and expense. If any indemnity furnished to the Administrative Agent for any purpose is, in the opinion of the Administrative Agent insufficient or becomes impaired, the Administrative Agent may call for additional indemnity and not commence or cease to do the acts indemnified against until such additional indemnity is furnished. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrowers.

	(iv)	If to any other Lender, to it at its address (or telecopy number) set forth in its Administrative Questionnaire.

(c) Except for notices required by Article 2, which shall be deemed given only when actually received by the Administrative Agent or the Issuing Bank, as the case may be, all such notices and communications shall, when personally delivered, delivered by courier, mailed or transmitted by telecopy, become effective (i) if personally delivered or delivered by courier, when received; (ii) if by mail, three (3) Business Days after such notice or other communication was deposited in the mail by certified mail, return receipt requested (with postage prepaid and addressed as aforesaid), or (iii) when sent by telecopy, when transmitted to the correct telecopier, with confirmation received.

(d) Notices and other communications to the Lenders and the Issuing Bank 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 2 unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrowers may, in their 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.

(e) Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement) and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient, at its e-mail address as described in the foregoing clause (i), of notification that such notice or communication is available and identifying the website address therefor; provided that, for both clauses (i) and (ii) above, if such notice, email or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient.

(f) Each Loan Party agrees that the Administrative Agent may, but shall not be obligated to, make the Communications (as defined below) available to the Issuing Bank and the other Lenders by posting the Communications on Debt Domain, Intralinks, Syndtrak or a substantially similar electronic transmission system (the “Platform”).The Platform is provided “as is” and “as available.” The Agent Parties (as defined below) do not warrant the adequacy of the Platform and expressly disclaim liability for errors or omissions in the Communications. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects, is made by any Agent Party in connection with the Communications or the Platform. In no event shall the Administrative Agent or any of its Related Parties (collectively, the “Agent Parties”) have any liability to either of the Borrowers or any other Loan Party, any Lender or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of any other Loan Party’s or the Administrative Agent’s transmission of communications through the Platform. “Communications” means, collectively, any notice, demand, communication, information, document or other material provided by or on behalf of any other Loan Party pursuant to any Loan Document or the transactions contemplated therein which is distributed to the Administrative Agent, any Lender or the Issuing Bank by means of electronic communications pursuant to this Section, including through the Platform.

(g) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto.

SECTION 9.2. Waivers; Amendments.

(a) No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document 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. No course of dealing between either of the Borrowers or any other Loan Party and any Lender, the Issuing Bank or the Administrative Agent shall operate as a waiver of any right of any Lender, the Issuing Bank or the Administrative Agent. 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 any other Loan Document or consent to any departure by either of the Borrowers or any other Loan Party 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. No notice to or demand on any Person shall entitle any Person to any or notice or demand in similar or other circumstances. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit 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 or any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers or the affected Loan Party and the Required Lenders, or by the Borrowers or the affected Loan Party and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall, without the written consent of each Lender adversely affected thereby, (i) increase any Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or any reimbursement obligation with respect to an LC Disbursement or reduce the rate of interest thereon, or reduce any fee payable hereunder, without the written consent of each Lender affected thereby; (iii) postpone the scheduled date of payment of any principal amount of any Loan or any reimbursement obligation with respect to an LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby; (iv) release any Material Domestic Subsidiary from its Guaranty Agreement or Lufkin from the Lufkin Guaranty or either of the Borrowers or any Material Domestic Subsidiary from its Security Document (except for Material Domestic Subsidiaries that cease to be Material Domestic Subsidiaries and Material Domestic Subsidiaries that are sold in transactions otherwise permitted hereunder, for which a release shall be provided by the Administrative Agent in accordance with Section 9.18) or limit its liability in respect of such Guaranty Agreement or Security Document, or waive the requirement that any Material Domestic Subsidiary execute and deliver a Guaranty Agreement or that either of the Borrowers or any Material Domestic Subsidiary execute and deliver a Security Document, or waive the obligation to provide, or release, any Cash Collateral provided pursuant to Section 2.05(k) or Section 7.02, without the consent of each Lender; (v) release any Collateral (except in accordance with Section 9.18) or waive the requirement that any Person required by this Agreement to execute and deliver a Security Document do so, without the consent of each Lender; (vi) change Section 2.20 in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender; or (vii) 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, without the written consent of each Lender; provided further that no amendment, waiver or consent shall affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender under this Agreement or any other Loan Document, unless in writing and signed by the Administrative Agent, the Issuing Bank, or the Swingline Lender respectively, in addition to the Lenders required above to take such action. Notwithstanding anything to the contrary herein, this Section 9.02, in respect of Defaulting Lender, shall be subject to Section 2.22.

SECTION 9.3. Expenses; Indemnity; Damage Waiver.

(a) The Borrowers jointly and severally shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent or the Sole Bookrunner and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank, any Lender, the Sole Bookrunner, the Joint Lead Arrangers, the Co-Syndication Agents or the Documentation Agent including the fees, charges and disbursements of any counsel for any such Person, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with any other Loan Document, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) To the fullest extent permitted by Law, neither the Administrative Agent, the Issuing Bank, the Sole Bookrunner, any Joint Lead Arranger, any Co-Syndication Agent, the Documentation Agent nor any Lender shall have any liability in connection with, and the Borrowers shall jointly and severally indemnify the Administrative Agent, the Issuing Bank, the Sole Bookrunner, each Joint Lead Arranger, each Co-Syndication Agent and the Documentation Agent and each Lender, and each Related Party of any of the foregoing Persons (each of the foregoing being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities, costs and related expenses (including costs of investigation and defense, legal fees and amounts paid in settlement) and the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee, INCLUDING LOSSES, LIABILITIES, OBLIGATIONS, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS ARISING FROM THE SOLE, CONCURRENT, ORDINARY OR CONTRIBUTORY NEGLIGENCE OF THE PERSON TO BE INDEMNIFIED, in connection with, arising out of, arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any of the other Loan Documents, or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto and the other Loan Parties of their respective obligations hereunder and under the other Loan Documents or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or Release of Hazardous Materials on or from any Property owned, leased or operated by either of the Borrowers or any of their respective Subsidiaries, in violation of any Environmental Law, or any Environmental Liability related in any way to either of the Borrowers or any of their respective Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence, illegal acts or willful misconduct of such Indemnitee. Any amount to be paid under this Section by the Borrowers to any Indemnitee shall be a demand obligation owing by the Borrowers to the Indemnitee and shall bear interest from the date of expenditure until paid at the Default Rate. The obligations of the Borrowers under this paragraph (b) shall survive the termination of this Agreement. This Section shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(c) To the extent that either Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank, the Swingline Lender or any Related Party under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank, the Swingline Lender or such Related Party, as the case may be, such Lender’s Applicable Percentage of the aggregate Credit Exposures (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that with respect to such unpaid amounts owed to the Issuing Bank or Swingline Lender solely in its capacity as such, only the Revolving Lenders shall be required to pay such unpaid amounts, such payment to be made severally among them based on such Revolving Lenders’ Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought); provided, further, 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, or against any Related Party of any of the foregoing acting for the Administrative Agent, the Issuing Bank or the Swingline Lender in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Section 2.02.

(d) To the extent permitted by applicable law, neither Borrower shall assert, and each Borrower 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, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be due not later than five (5) Business Days after written demand therefor.

(f) Without prejudice to the survival of any other agreement of the Borrowers in the Loan Documents, the agreements and obligations of the Borrowers and the Lenders contained in this Section shall survive the payment in full of the Loans and all other amounts payable under this Agreement and the other Loan Documents, the expiration of all Letters of Credit, and the termination of this Agreement.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that neither any Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement or any other Loan Document, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Indemnitees Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (in each case with respect to any Class) any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Loans at the time owing to it (in each case with respect to any Class) or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000 with respect to each Class of Commitment, in the case of any assignment, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, Lufkin otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of Lufkin (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that Lufkin shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 5 Business Days after having received notice thereof and provided, further, that Lufkin’s consent shall not be required during the primary syndication of this Agreement;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of (i) the Revolving Loans or any unfunded Revolving Commitments or any unfunded Term Loan Commitments if such assignment is to a Person that is not a Lender with a Commitment in respect of such Class, an Affiliate of such Lender or an Approved Fund with respect to such Lender, or (ii) any Term Loans to a Person who is not a Lender, an Affiliate of a Lender or an Approved Fund; and

(C) the consent of the Issuing Bank and Swingline Lender shall be required for any assignment in respect of the Revolving Loans or Revolving Commitments.

(iv) Assignment and Assumption. 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; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) either Borrower or any of either Borrower’s Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of Lufkin and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Bank, the Swingline Lender and each other Lender hereunder (and unpaid interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender 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 2.16, 2.17, 2.18 and 9.03 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph 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 (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at one of its offices in New York City 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 Commitments of, and principal amounts (and stated interest) of the Loans and obligations relating to LC Exposure owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent, the Issuing Bank and the Lenders shall 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 Borrowers, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, either of the Borrowers, the Administrative Agent or the Issuing Bank, sell participations to any Person (other than a natural Person or a Borrower or any of the Affiliates or Subsidiaries of either Borrower) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitments and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrowers, the Administrative Agent, the Issuing Bank and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 8.11 with respect to any payments made by such Lender to its Participant(s).

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 the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Document; provided that 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 of Section 9.02(b) that affects such Participant. The Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.16, 2.17 and 2.18 (subject to the requirements and limitations therein, including the requirements under Section 2.18 (it being understood that the documentation required under Section 2.18 shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 2.21 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Section 2.16, 2.17 or 2.18 with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrowers’ request and expense, to use reasonable efforts to cooperate with the Borrowers to effectuate the provisions of Section 2.21 with respect to any Participant. 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 that such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (at no cost to any other Loan Party) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(f) Disclosure. Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section, disclose to the assignee or participant or proposed assignee or participant any information relating to either of the Borrowers, any other Loan Party, or any Subsidiary of either Borrower; provided that such assignee or participant or proposed assignee or participant is instructed that its review, copying or retention of such information will act as its agreement to be bound by Section 9.16.

SECTION 9.5. Return of Payments. If at any time all or any part of any payment or any proceeds of any Collateral or any proceeds of any enforcement or set-off is or must be returned by or recovered from the Administrative Agent, the Issuing Bank, the Swingline Lender or any other Lender for any reason (including the order of any bankruptcy court), then, to the extent permitted by law, the Obligations or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and shall continue in full force and effect, and the rights, powers and remedies of the Administrative Agent, the Issuing Bank, the Swingline Lender or other Lender under this Agreement and each other Loan Document shall continue in full force and effect, as if such payment had not been made or such enforcement or setoff had not occurred. In such event, each Loan Document shall be automatically reinstated and each Borrower shall take or cause to be taken such action as may be reasonably requested by the Administrative Agent to effect such reinstatement. The Borrowers jointly and severally shall indemnify the Administrative Agent, the Issuing Bank, the Swingline Lender and the other Lenders against, and save and hold each of such parties harmless from, any required return by or recovery of any such payment because of its being deemed preferential under any applicable law or for any other reason.

SECTION 9.6. Counterparts; Integration; Effectiveness; Electronic Execution.

(a) 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, the other Loan Documents 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 and 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 or by electronic photocopy (i.e., “pdf”) shall be effective as delivery of a manually executed counterpart of this Agreement.

(b) The words “execution,” “signed,” “signature,” or words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

SECTION 9.7. Severability. Should any clause, sentence, paragraph or section of this Agreement or any other Loan Document be judicially declared to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement or such other Loan Document, and the part or parts of this Agreement or such other Loan Document so held to be invalid, unenforceable or void will be deemed to have been stricken and the remainder will have the same force and effectiveness as if such part or parts had never been included herein or therein. Each covenant contained in any Loan Document shall be construed (absent an express contrary provision herein) as being independent of each other covenant contained therein, and compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with one or more other covenants.

SECTION 9.8. Right of Setoff.(a)If an Event of Default shall have occurred and be continuing, each Lender and the Issuing Bank and each of their respective Affiliates is hereby authorized, without notice to any Person, at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Issuing Bank or any such Affiliate to or for the credit or the account of either of the Borrowers or any other Loan Party against any and all of the obligations of either of the Borrowers or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or the Issuing Bank, irrespective of whether or not such Lender or the Issuing Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of such Borrower or any other Loan Party may be contingent or unmatured or are owed to a branch or office of such Lender or the Issuing Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify Lufkin and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application, and provided that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.22 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Bank, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. For purposes of effectuating the setoff rights of the Lenders and the Issuing Bank and their respective Affiliates pursuant to this Section 9.08 (and for no other purpose), the Borrowers and each other Loan Party expressly agree to treat each Lender, the Issuing Bank and each of their respective Affiliates (including each of their respective branches and offices) as a single entity; it being the express intent of the Borrowers and each other Loan Party to maximize the available deposits that may be set off against any and all Obligations of the Borrowers or such other Loan Party under this Agreement or any other Loan Document. ANY AND ALL RIGHTS TO REQUIRE ANY LENDER OR THE ISSUING BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL THAT SECURES THE OBLIGATIONS PRIOR TO EXERCISING ITS RIGHT TO SET-OFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF EITHER OF THE BORROWERS OR ANY OTHER LOAN PARTY ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

(1) If any Lender or the Issuing Bank 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 resulting in such Lender’s or the Issuing Bank’s receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, the Lender receiving such greater proportion or the Issuing Bank shall notify the Administrative Agent of that fact and shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; 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 a 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 a Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply).

The Borrowers consent to the foregoing and agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against any Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

SECTION 9.14. Relationship of the Parties. (a)The relationship between the Borrowers and each other Loan Party, on the one hand, and the Administrative Agent, the Lenders, the Issuing Bank and their respective Affiliates, on the other hand, in connection with all aspects of the Transactions and any communications in connection therewith is solely that of debtor and creditor, and neither the Administrative Agent, any Lender, nor the Issuing Bank has any fiduciary or other special relationship to either of the Borrowers or any other Loan Party or any of their respective Affiliates, and no term, provision, or condition of any of the Loan Documents shall be construed so as to deem the relationship between either of the Borrowers and any Lender, between any Subsidiary and any Lender, or between any such Affiliate and any Lender to be other than that of debtor and creditor. No joint venture or partnership is created by this Agreement among the Lenders or among either of the Borrowers, or any Subsidiary of either of the Borrowers, or any of their respective Affiliates, and the Lenders.

(b) The provisions herein for compliance with financial, environmental, and other covenants, delivery of financial, environmental and other reports, and financial, environmental and other inspections, investigations, audits, examinations or tests are intended solely for the benefit of the Lenders and the Issuing Bank to protect their interests as lenders and issuers of letters of credit in assuming payments of interest and repayment of principal, and nothing contained in this Agreement or in any other Loan Document shall be construed as permitting or obligating the Lenders to act as financial or business advisors or consultants to either of the Borrowers, as permitting or obligating the Lenders to control either of the Borrowers or any other Loan Party or to conduct or operate either of the Borrowers’ or any other Loan Party’s operations.

(c) Each Borrower, the Administrative Agent, the Issuing Bank and each Lender acknowledges that it has had the opportunity to obtain the advice of experienced counsel of its own choosing in connection with the negotiation and execution of this Agreement and to obtain the advice of such counsel with respect to all matters contained herein, including, without limitation, the provision for waiver of trial by jury.

SECTION 9.15. Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default if such action is taken or such condition exists.

SECTION 9.16. Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders (on behalf of itself and each of its Affiliates) agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, members, managers, 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 any other Loan Document or the enforcement of rights hereunder or thereunder, (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 either Borrower and its obligations, (g) with the consent of Lufkin, 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 Borrowers. For the purposes of this Section, “Information” means all information received from either of the Borrowers or any of their respective Subsidiaries relating to either of the Borrowers or any of their respective Subsidiaries or any other Loan Party or any of their respective businesses, 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 either of the Borrowers; provided that, in the case of information received from either of the Borrowers, any of their respective Subsidiaries or any other Loan Party after the date hereof, such information is clearly identified in writing 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.

Notwithstanding the foregoing, the Administrative Agent may provide information relating to the Loans to Gold Sheets, and other similar bank trade publications, with such information to consist of deal terms consisting of (i) the Borrowers’ names, (ii) principal loan amounts, (iii) interest rate, (iv) term length and (v) the Unused Commitment Fee Rate and other fees to the Lenders in the syndicate, the identity of their attorneys and other information customarily found in such publications.

SECTION 9.17. Interest. It is the intent of the parties in the execution and performance of this Agreement to contract in strict compliance with all applicable usury laws from time to time in effect. Each provision in this Agreement and each other Loan Document is expressly limited so that in no event whatsoever shall the amount paid, or otherwise agreed to be paid, to the Administrative Agent, the Issuing Bank or any Lender or charged, contracted for, reserved, taken or received by the Administrative Agent, the Issuing Bank or any such Lender for the use, forbearance or detention of the money to be loaned under this Agreement or any Loan Document or otherwise (including any sums paid as required by any covenant or obligation contained herein or in any other Loan Document which is for the use, forbearance or detention of such money), exceed that amount of money which would cause the rate of interest to exceed the Highest Lawful Rate, and all amounts owed under this Agreement and each other Loan Document shall be held to be subject to reduction to the effect that such amounts so paid or agreed to be paid, charged, contracted for, reserved, taken or received which are for the use, forbearance or detention of money under this Agreement or such Loan Document shall in no event exceed that amount of money which would cause the effective rate of interest to exceed the Highest Lawful Rate. Anything in any Note or any other Loan Document to the contrary notwithstanding, no Borrower shall be required to pay unearned interest on any Loan and no Borrower shall be required to pay interest on the Obligations at a rate in excess of the Highest Lawful Rate, and if the effective rate of interest which would otherwise be payable under in connection with such Loan or such Note and such Loan Documents would exceed the Highest Lawful Rate, or if the holder of any such Note shall receive any unearned interest or shall receive monies that are deemed to constitute interest which would increase the effective rate of interest payable under such Loan and the other Loan Documents to a rate in excess of the Highest Lawful Rate, then (a) the amount of interest which would otherwise be payable by the applicable Borrower shall be reduced to the amount allowed under applicable law, and (b) any unearned interest paid by either Borrower or any interest paid by either Borrower in excess of the Highest Lawful Rate shall in the first instance be credited on the principal of the obligations of such Borrower (or if all such obligations shall have been paid in full, refunded to such Borrower).In determining whether or not the rate of interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate, the Borrowers and the Lenders shall, to the maximum extent permitted under applicable law, (a) treat all Loans and Borrowings as but a single extension of credit (and the Borrowers and the Lenders agree that such is the case and that provision herein for multiple Loans and Notes is for convenience only); (b) characterize any nonprincipal payment as an expense, fee or premium rather than as interest; and (c) exclude voluntary prepayments and the effects thereof. The provisions of this Section shall control over all other provisions of the Loan Documents which may be in apparent conflict herewith.

Without limitation of the foregoing, nothing in this Agreement or in any other Loan Document shall be deemed to constitute a waiver of any rights which any Lender, the Issuing Bank, the lender of any Loan or the holder of any Note may have under applicable federal law relating to the amount of interest which such Lender or holder or the Issuing Bank may contract for, take, receive or charge in respect of the Loans, the Letters of Credit and the Loan Documents, including any right to take, receive, reserve and charge interest at the rate allowed by the law of the state where any Lender is located.

SECTION 9.18. Release of Liens and Guarantees.

(a) Lufkin may request the release under the Guaranty Agreement of any Guarantor or the release under the Security Document of any Collateral to be sold or otherwise disposed of (including through the sale or disposition of any Subsidiary owning any such Subsidiary or Collateral or resulting from the dissolution of a Subsidiary) to a Person other than a Borrower or any other consolidated Subsidiary in a transaction not prohibited under the terms of this Agreement as a result of which such Subsidiary ceases to be a Subsidiary, provided that (i) each of the representations and warranties of the Borrowers and the other Loan Parties contained in the Loan Documents (including those relating to Material Adverse Effect and litigation, but excluding those representations and warranties limited by their terms to a specific date, in which case they shall have been true and correct as of such date) shall be true and correct on and as of the date of such release and (ii) on the date of such release, no Event of Default or Default shall have occurred and be continuing or result therefrom.

(b) To request such a release, Lufkin shall deliver to the Administrative Agent a certificate executed by a Financial Officer to the effect that such sale or other disposition (and any dissolution relating thereto, and, if applicable, the application of the proceeds thereof) will comply with the terms of this Agreement, together with such other evidence that the Administrative Agent may reasonably request in order to verify the statements made in such certificate.

(c) Upon receipt of such certificate, the Administrative Agent, if satisfied that such certificate is correct, shall, without the consent of any Lender or the Issuing Bank, execute and deliver all such instruments, releases, financing statements or other agreements, and take all such further actions, as Lufkin may reasonably request to effectuate the release of such Subsidiary or such Collateral substantially simultaneously with or at any time after the completion of such sale or other disposition. Any such release shall be without recourse to, or representation or warranty by, the Administrative Agent and shall not require the consent of any Lender or the Issuing Bank.

(d) If Lufkin shall request the release under a Security Document or a Guaranty Agreement of any Subsidiary or any Collateral due to the fact that such Subsidiary no longer qualifies as a Material Subsidiary pursuant to the definition thereof, Lufkin shall deliver to the Administrative Agent a certificate executed by a Financial Officer to the effect that such Subsidiary is no longer a Material Subsidiary, together with any documents or other evidence that the Administrative Agent may reasonably request in order to verify the statements made in such certificate, and the Administrative Agent, if satisfied that such certificate is correct, shall, without the consent of any Lender or the Issuing Bank, execute and deliver all such instruments, releases, financing statements or other agreements, and take all such further actions, as Lufkin shall reasonably request to effectuate the release of such Subsidiary or such Collateral. Any such release shall be without recourse to, or representation or warranty by, the Administrative Agent and shall not require the consent of any Lender or the Issuing Bank.

(e) Without limiting the provisions of Section 9.03, the Borrowers jointly and severally shall reimburse the Administrative Agent and the Lenders for all costs and expenses, including attorneys’ fees and disbursements, incurred by any of them in connection with any action contemplated by this Section 9.18.

SECTION 9.19. Survival. All covenants, agreements, representations and warranties made by or on behalf of the Borrowers, or either of them, or any other Loan Party in connection with this Agreement or any of the other Loan Documents or in any certificate or other instrument delivered in connection with or pursuant to this Agreement or any other Loan Document 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 other Loan Documents and the making of any Loans and the issuance of any Letter of Credit, 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, any unreimbursed LC Disbursement, or any fee or any other Obligations payable under this Agreement or any other Loan Document is outstanding and unpaid or any LC Exposure exists and so long as the Commitments have not expired or terminated. The provisions of Sections 2.16, 2.17, 2.18 and 9.03 and Article 8 shall survive and remain in full force and effect regardless of the consummation of the Transactions, the repayment of the Loans and the other Obligations, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof. No Person other than the Borrowers and their respective Subsidiaries shall have any right to the proceeds of Loans at any time, the Loans shall not constitute a trust fund for the benefit of any third party, and no third party shall under any circumstances have or be entitled to any Lien or any trust impressed on any undisbursed Loans.

SECTION 9.20. Anti-Money Laundering Legislation.

(a) Each Loan Party acknowledges that, pursuant to the Canadian AML Legislation, the Administrative Agent, the Issuing Bank and the Lenders may be required to obtain, verify and record information regarding each Loan Party and ▇▇▇▇▇’▇ and its Subsidiaries, their respective directors, authorized signing officers, direct or indirect shareholders or other Persons in control thereof and the transactions contemplated hereby. The Borrowers shall promptly provide, and shall cause their respective Subsidiaries to promptly provide, all such information, including supporting documentation and other evidence, as may be reasonably requested by the Administrative Agent, the Issuing Bank or any Lender, or any prospective assignee or participant of the Issuing Bank or a Lender, in order to comply with any applicable Canadian AML Legislation, whether now or hereafter in existence.

(b) If the Administrative Agent has ascertained the identity of the Loan Parties or any authorized signatories of the Loan Parties for the purposes of applicable Canadian AML Legislation, the Administrative Agent:

(i) shall be deemed to have done so as an agent for each Lender, and this Agreement shall constitute a “written agreement” in such regard between each Lender and the Administrative Agent within the meaning of applicable Canadian AML Legislation; and

(ii) shall provide to each Lender copies of all information obtained in such regard without any representation or warranty as to its accuracy or completeness.

Notwithstanding the preceding sentence and except as may otherwise be agreed in writing, each of the Lenders agrees that the Administrative Agent has no obligation to ascertain the identity of the Loan Parties or any authorized signatories of the Loan Parties on behalf of any Lender, or to confirm the completeness or accuracy of any information it obtains from the Loan Parties or any such authorized signatory in doing so.

SECTION 9.21. Amendment and Restatement of Existing Credit Agreement.

(a) On the Effective Date the Existing Credit Agreement shall be amended, restated and superseded in its entirety hereby. The parties hereto acknowledge and agree that (i) this Agreement, any promissory notes delivered pursuant to Section 4.01(c) or Section 4.02, and the other Loan Documents executed and delivered in connection herewith do not constitute a novation or termination of the “Obligations” (as defined in the Existing Credit Agreement) under the Existing Credit Agreement as in effect prior to the Effective Date and (ii) such “Obligations” are in all respects continuing with only the terms thereof being modified as provided in this Agreement.

(b) Notwithstanding the modifications effected by this Agreement of the representations, warranties and covenants of Lufkin contained in the Existing Credit Agreement, each Borrower acknowledges and agrees that any causes of action or other rights created in favor of the Administrative Agent, any Issuing Bank or any Lender, in each case, party to or its successors arising out of the representations and warranties of Lufkin contained in or delivered in connection with the Existing Credit Agreement shall survive the execution, delivery and effectiveness of this Agreement to the extent provided in the Existing Credit Agreement.

(c) All indemnification obligations of Lufkin arising under the Existing Credit Agreement (including any arising from a breach of the representations thereunder) shall survive to the extent provided in the Existing Agreement.

SECTION 9.22. USA Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies each Loan Party that pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies each Loan Party, which information includes the name, taxpayer identification number and business address of such Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Loan Party in accordance with the USA Patriot Act. The Administrative Agent may also ask to see the legal organizational documents or other identifying documents of the Borrowers.

EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.16 (CONFIDENTIALITY) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE BORROWERS AND THEIR AFFILIATES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS 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, PROVINCIAL, TERRITORIAL AND STATE SECURITIES LAWS.

ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY A BORROWER OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL NONPUBLIC INFORMATION ABOUT THE BORROWERS, THE OTHER LOAN PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO THE BORROWERS AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL, PROVINCIAL, TERRITORIAL AND STATE SECURITIES LAWS.

IN WITNESS WHEREOF, the parties to this Agreement have caused it to be signed by their respective duly authorized officers.

The Debt includes interest and other obligations accruing or arising after (a) commencement of any case under any bankruptcy or similar laws by or against any Obligor or (b) the obligations of any Obligor shall cease to exist by operation of law or for any other reason. The Debt also includes all reasonable attorneys’ fees and any other expenses incurred by the Administrative Agent, the Issuing Bank or any Lender in enforcing any of the Loan Documents.

Lender means a Lender from time to time under the Credit Agreement and shall include the Issuing Bank and the Swingline Lender.

ARTICLE II

2.1 Execution of Loan Documents. The Borrowers have executed and delivered the Credit Agreement and other Loan Documents to the Lenders, the Issuing Bank and the Administrative Agent.

2.2 Consideration. In consideration of the credit and other financial accommodations extended and contemplated to be extended to the Borrowers by the Lenders, the Issuing Bank and the Administrative Agent pursuant to the Loan Documents or otherwise, which Guarantor has determined will substantially benefit Guarantor directly or indirectly, and for other good and valuable consideration, the receipt and sufficiency of which Guarantor hereby acknowledges, Guarantor executes and delivers this Guaranty to the Lenders, the Issuing Bank and the Administrative Agent, with the intention of being presently and legally bound by its terms.

ARTICLE III

3.1 Payment Guaranty.

(a) In order to induce the Lenders, the Issuing Bank and the Administrative Agent to enter into the Credit Agreement and to extend credit from time to time thereunder, and in consideration thereof, Guarantor, as a primary obligor and not as a surety, severally unconditionally and irrevocably guarantees to the Lenders, the Issuing Bank and the Administrative Agent the full, prompt and punctual payment and performance of the Debt when due (whether at stated maturity, by acceleration or otherwise) in accordance with the Loan Documents. This Guaranty is irrevocable, unconditional and absolute, and if for any reason all or any portion of the Debt shall not be paid when due, Guarantor agrees immediately to pay the Debt to the Lenders or other Person entitled to it, in Dollars, regardless of (i) any defense, right of set-off or counterclaim which Guarantor may have or assert, (ii) whether any other such Person shall have taken any steps to enforce any rights against either or both Borrowers or any other Person to collect any of the Debt, and (iii) any other circumstance, condition or contingency.

(b) NOTWITHSTANDING THE FOREGOING, to the extent that in a legal proceeding brought within the applicable limitations period it is determined by the final, non-appealable order of a court having jurisdiction over the issue and the relevant parties that Guarantor at a time when it was not Solvent received less than a reasonably equivalent value in exchange for Guarantor’s incurrence of its obligations under this Guaranty, then and only then the liability of Guarantor under this Guaranty shall be limited to an amount equal to the maximum amount which Guarantor could pay or be liable for under this Guaranty without having such payment or liability set aside as a fraudulent conveyance or fraudulent transfer or other similar action under any applicable bankruptcy, insolvency or other similar law of any jurisdiction. The Lenders acting through the Administrative Agent shall have the right to determine and designate from time to time, without notice to or assent of Guarantor, which portions of the Debt such limitation applies to, and Guarantor acknowledges that such determination and designation shall be conclusive on all parties. This Guaranty shall not fail or be ineffective or invalid or be considered too indefinite or contingent with respect to Guarantor because the Guaranteed Debt of Guarantor may fluctuate from time to time, or for any other reason.

3.2 Application. Guarantor agrees that any payment or prepayment by Guarantor or any other Person against the Debt shall be deemed paid first against that portion of the Debt not included in “Guaranteed Debt” of Guarantor or determined for any reason not to be a part of “Guaranteed Debt” of Guarantor, and then shall be paid against any portion of the Debt that is Guaranteed Debt of Guarantor, in such order and manner as the Lenders and the Issuing Bank or the Administrative Agent shall determine in their respective sole and absolute discretion.

3.3 Notification. Guarantor agrees that whenever, at any time, or from time to time, it shall make any payment to the Administrative Agent, the Issuing Bank or any Lender on account of its liability under this Guaranty, it will notify the Administrative Agent in writing that such payment is made under this Guaranty. No payment or payments made by either Borrower or any other Person or received or collected by the Administrative Agent, the Issuing Bank or any Lender from either or both Borrowers or any other Person by virtue of any action or proceeding or any setoff or appropriation or application, at any time or from time to time, in reduction of or in payment of the Debt shall be deemed to modify, reduce, release or otherwise affect the liability of Guarantor under this Guaranty.

3.4 Amendments, Etc. with Respect to the Obligations. Guarantor shall remain obligated under this Guaranty notwithstanding that, without any reservation of rights against Guarantor or any other guarantor of any of the Obligations, and without notice to or further assent by Guarantor or any other guarantor of any of the Obligations, (a) any demand for payment of or reduction in the principal amount of any of the Obligations made by the Administrative Agent, the Issuing Bank or any Lender is rescinded by the Administrative Agent, the Issuing Bank or such Lender, (b) any of the Obligations is extended, continued, or modified, or (c) any of the Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, is, from time to time, in whole or in part, renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent, the Issuing Bank or any Lender. The Credit Agreement and the other Loan Documents may from time to time be amended, modified, supplemented or terminated, in whole or in part, in accordance with their respective terms, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent, the Issuing Bank or any Lender for the payment of the Obligations may be sold, exchanged, waived, surrendered or released, all without in any way releasing, diminishing, reducing, impairing or otherwise affecting the obligations of Guarantor under this Guaranty. Neither the Administrative Agent, the Issuing Bank nor any Lender shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for the guarantees contained in this Guaranty or any property subject thereto.

Guarantor WAIVES diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon Guarantor or either or both Borrowers or any other Obligor with respect to the Obligations. This Guaranty shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the legality, validity or enforceability of the Credit Agreement or any other Loan Document, any of the Obligations or any collateral security therefor or any guarantee or right of offset with respect thereto at any time or from time to time held or purported to be held by the Administrative Agent, the Issuing Bank or any Lender, (b) the legality under any applicable law of repayment by either Borrower or any other Obligor of any of the Obligations or the adoption or application of any law purporting to render any such Obligations null and void, (c) any defense, setoff or counterclaim which may at any time be available to or be asserted by Guarantor against the Administrative Agent, the Issuing Bank or any Lender, or (d) any other circumstance whatsoever (with or without notice to or knowledge of Guarantor or either Borrower or any other Obligor) which constitutes, or might be construed to constitute, an equitable or legal discharge of either or both Borrowers or any other Obligor for any of the Obligations, or of Guarantor under this Guaranty, in bankruptcy or in any other instance. The Administrative Agent, the Issuing Bank or any Lender may, but shall be under no obligation to, pursue such rights and remedies as it may have against either Borrower, Guarantor or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent, the Issuing Bank or any Lender to pursue such other rights or remedies or to collect any payments from either or both Borrowers, Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of either Borrower, Guarantor or any such other Person or of any such collateral security, guarantee or right of offset, shall not relieve Guarantor of any liability under this Guaranty and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent, the Issuing Bank or any Lender against Guarantor.

3.5 Obligations Not Affected. Guarantor’s covenants, agreements and obligations under this Guaranty shall in no way be released, diminished, reduced, impaired or otherwise affected by reason of the happening from time to time of any of the following things, for any reason, whether by voluntary act, operation of law or order of any competent Governmental Authority, and whether or not Guarantor is given any notice or is asked for or gives any further consent (all requirements for which, however arising, Guarantor hereby WAIVES):

(a) release or waiver of any obligation or duty to perform or observe any express or implied agreement, covenant, term or condition imposed in any of the Loan Documents or by applicable law on either or both Borrowers or any other party to the Loan Documents.

(b) extension of the time for payment of any part of the Obligations or any other sums payable under the Loan Documents, extension of the time for performance of any other obligation under or arising out of or in connection with the Loan Documents or change in the manner, place or other terms of such payment or performance.

(d) renewal, supplementing, modification, rearrangement, amendment, restatement, replacement, cancellation, rescission, revocation or reinstatement (whether or not material) of all or any part of any of the Loan Documents or any obligation under the Loan Documents of either Borrower or any other party to the Loan Documents (without limitation on the number of times any of the foregoing may occur).

(e) acceleration of the time for payment or performance of any Obligations or other obligation under any of the Loan Documents or exercise of any other right, privilege or remedy under or in regard to any of the Loan Documents.

(f) failure, omission, delay, neglect, refusal or lack of diligence by the Administrative Agent, the Issuing Bank or any Lender or any other Person to assert, enforce, give notice of intent to exercise -- or any other notice with respect to -- or exercise any right, privilege, power or remedy conferred on the Administrative Agent, the Issuing Bank or any Lender or any other Person in any of the Loan Documents or by law or action on the part of the Administrative Agent, the Issuing Bank or any Lender or any other Person granting indulgence, grace, adjustment, forbearance or extension of any kind to either Borrower or any other Person.

(g) taking or acceptance of any security or any other guaranty for the payment or performance of any or all of the Obligations.

(h) voluntary or involuntary liquidation, dissolution, sale of any collateral, marshaling of assets and liabilities, change in corporate or organizational status, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt or other similar proceedings of or affecting either Borrower or any other Obligor or Guarantor or any of the assets of either Borrower or any other Obligor or Guarantor, even if any of the Obligations is thereby rendered void, unenforceable or uncollectible.

(i) occurrence or discovery of any lack of genuineness, irregularity, invalidity or unenforceability of any of the Obligations or Loan Documents or any defect or deficiency in any of the Obligations or Loan Documents.

(j) failure by the Administrative Agent, the Issuing Bank, any Lender or any other Person to notify -- or timely notify -- Guarantor of any default, event of default or similar event (however denominated) under any of the Loan Documents, or of any renewal, extension, supplementing, modification, rearrangement, amendment, restatement, replacement, cancellation, rescission, revocation or reinstatement (whether or not material) or assignment of all or any part of the Obligations, release or exchange of any security, other action taken or not taken by the Administrative Agent, the Issuing Bank or any Lender against either Borrower, Guarantor or any other Person, or any other event or circumstance. Neither the Administrative Agent, the Issuing Bank nor any Lender shall have any duty or obligation to give Guarantor any notice of any kind under any circumstances whatsoever with respect to or in connection with the Obligations or this Guaranty.

(k) occurrence of any event or circumstance which might otherwise constitute a defense available to, or a discharge of, either or both Borrowers or any other Obligor or Guarantor, including failure of consideration, fraud by or affecting any Person, usury, forgery, breach of warranty, failure to satisfy any requirement of the statute of frauds, running of any statute of limitation, accord and satisfaction and any defense based on election of remedies of any type.

(l) receipt and/or application of any proceeds, credits or recoveries from any source, including any proceeds, credits, or amounts realized from exercise of any rights, remedies, powers or privileges of the Administrative Agent, the Issuing Bank or any Lender under any of the Loan Documents, by law or otherwise available to the Administrative Agent, the Issuing Bank or any Lender.

(m) occurrence of any act, error or omission of the Administrative Agent, the Issuing Bank or any Lender, except behavior which is proven to be in bad faith to the extent (but no further) that Guarantor cannot effectively waive the right to complain.

3.6 Waivers. Guarantor hereby WAIVES and RELEASES all right to require marshaling of assets and liabilities, sale in inverse order of alienation, notice of acceptance of this Guaranty and of any liability to which it applies or may apply, notice of the creation, accrual, renewal, increase, extension, modification, amendment or rearrangement of all or any part of the Obligations, presentment, demand for payment, protest, notice of nonpayment, notice of dishonor, notice of intent to accelerate, notice of acceleration and all other notices and demands, collection suit and the taking of any other action by the Administrative Agent, the Issuing Bank or any Lender.

3.7 Guaranty of Payment and Not of Collection. This is an absolute guaranty of payment and not of collection, and an absolute guaranty of performance of all of the obligations of each Borrower under the Loan Documents, and Guarantor WAIVES any right to require that any action be brought against either Borrower or any other Person, or that the Administrative Agent, the Issuing Bank or any Lender be required to enforce, attempt to enforce or exhaust any rights, benefits or privileges of the Administrative Agent, the Issuing Bank or any Lender under any of the Loan Documents, by law or otherwise; provided that nothing herein shall be construed to prevent the Administrative Agent, the Issuing Bank or any Lender from exercising and enforcing at any time any right, benefit or privilege which the Administrative Agent, the Issuing Bank or such Lender may have under any Loan Document or by law from time to time, and at any time. Guarantor agrees that Guarantor’s obligations hereunder are – and shall be – absolute, independent, and unconditional under any and all circumstances. Should the Administrative Agent, the Issuing Bank or any Lender seek to enforce Guarantor’s obligations by action in any court, Guarantor WAIVES any requirement, substantive or procedural, that (a) the Administrative Agent, the Issuing Bank or any Lender pursue any foreclosure action, realize or attempt to realize on any security or preserve or enforce any deficiency claim against either or both Borrowers, Guarantor or any other Person after any such realization, (b) a judgment first be sought or rendered against either or both Borrowers, Guarantor or any other Person, (c) either or both Borrowers, Guarantor or any other Person be joined in such action, or (d) a separate ac¬tion be brought against either or both Borrowers, Guarantor or any other Person. Guarantor’s obligations under this Guaranty are several from those of either or both Borrowers or any other Person and are primary obligations concerning which Guarantor is the principal obligor. All waivers in this Guaranty or any of the other Loan Documents shall be without prejudice to the right of the Administrative Agent, the Issuing Bank or any Lender at its option to proceed against either or both Borrowers, Guarantor or any other Person, whether by separate action or by joinder. Guarantor agrees that its obligations under this Guaranty shall not be discharged except by payment of the Obligations in full, complete performance of all obligations of the Borrowers and the other Obligors under the Loan Documents and termination of the Lenders’ obligations if any -- to make any further advances under the Loan Documents or extend other financial accommodations to either or both Borrowers.

3.8 Obligations Joint and Several with Other Guaranties. If any other Person makes any guaranty of any of the Obligations or gives any security for them, Guarantor’s obligations under this Guaranty shall be joint and several with the obligations of such other Person pursuant to such agreement or other papers making the guaranty or giving the security.

3.9 Reinstatement. Guarantor agrees that, if at any time all or any part of any payment previously applied by the Administrative Agent, the Issuing Bank or any Lender to the Obligations is or must be returned by the Administrative Agent, the Issuing Bank or such Lender – or recovered from the Administrative Agent or such Lender – for any reason (including the order of any bankruptcy court), this Guaranty shall automatically be reinstated to the same effect as if the prior application had not been made, and, in addition, Guarantor hereby agrees to indemnify the Administrative Agent, the Issuing Bank and each Lender against, and to save and hold the Administrative Agent, the Issuing Bank and each Lender harmless from, any required return by the Administrative Agent, the Issuing Bank or any Lender – or recovery from the Administrative Agent or any Lender – of any such payment because of its being deemed preferential under applicable bankruptcy, receivership or insolvency laws, or for any other reason. The provisions of this Section 3.9 shall survive the termination of this Guaranty and any satisfaction and discharge of either or both Borrowers or any other Obligor by virtue of any payment, court order or other law.

3.10 Effect of Stay. If an event permitting the acceleration of any of the Obligations shall at any time have occurred and be continuing and such acceleration shall at such time be prevented by reason of the pendency against either or both Borrowers or any other Obligor of a case or proceeding under any bankruptcy or insolvency law, Guarantor agrees that, for purposes of this Guaranty and its obligations hereunder, the Obligations shall be deemed to have been accelerated and Guarantor shall forthwith pay such Obligations (including interest which but for the filing of such petition in bankruptcy would accrue on such Obligations), and the other obligations hereunder, without any further notice or demand. Guarantor agrees that, as between Guarantor and the Lenders, the Issuing Bank and the Administrative Agent, the Debt may be declared to be due and payable for the purposes of this Guaranty notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards either or both Borrowers and that in the event of a declaration or attempted declaration, Guarantor’s Guaranteed Debt shall immediately become due and payable by Guarantor for the purposes of this Guaranty.

3.11 Subrogation and Contribution. Guarantor expressly agrees that it will not be entitled to enforce any and all rights of subrogation, reimbursement, contribution, exoneration and indemnity, contractual, statutory or otherwise, against the Administrative Agent, the Issuing Bank and the Lenders individually and collectively, including any claim or right of subrogation under the Bankruptcy Code (Title 11 of the U.S. Code) or any successor or similar Law arising from the existence or performance of this Guaranty, until the termination of this Guaranty, and until such termination Guarantor irrevocably agrees that it will not be entitled to enforce any right to enforce any remedy which the Administrative Agent, the Issuing Bank or any Lender now has or may hereafter have against either or both Borrowers or any other Obligor and the benefit of and any right to participate in any security now or hereafter held by the Administrative Agent, the Issuing Bank or any Lender. Until such termination, if any amount shall be paid by or on behalf of either Borrower or any other Person to Guarantor on account of any of the rights waived in this Section 3.11, such amount shall be held by Guarantor in trust, segregated from other funds of Guarantor, and shall, forthwith upon receipt by Guarantor, be turned over to the Administrative Agent for the account of the Issuing Bank and each Lender in the exact form received by Guarantor (duly indorsed by Guarantor to the Administrative Agent, the Issuing Bank or such Lender, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine. The provisions of this Section 3.11 shall survive the term of this Guaranty, the payment in full of the Obligations and the termination of the Commitments.

3.12 Administrative Matters. If, in the exercise of any of its rights and remedies, the Administrative Agent, the Issuing Bank or any Lender shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against either or both Borrowers or any other Obligor or Guarantor, for any reason, Guarantor hereby consents to such action, even if such action by the Administrative Agent, the Issuing Bank or such Lender shall result in a full or partial loss of any rights of subrogation which Guarantor might otherwise have had but for such action by the Administrative Agent, the Issuing Bank or such Lender. Any election of remedies which results in the denial or impairment of the right of the Administrative Agent, the Issuing Bank or any Lender to seek a deficiency judgment against either or both Borrowers or any other Obligor shall not impair Guarantor’s obligation to pay the full amount of Guarantor’s Guaranteed Debt.

3.13 Certain Taxes. Guarantor further agrees that all payments to be made hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction for, any taxes, levies, imposts, duties, charges, fees, deductions, withholdings or restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed by any country or by any political subdivision or taxing authority thereof or therein (“Taxes”). If any Taxes are required to be withheld from any amounts payable hereunder, the amounts so payable shall be increased to the extent necessary to yield to the recipient thereof (after payment of all Taxes) the amount payable hereunder in the full amounts so to be paid. Whenever any Tax is paid by a Guarantor, as promptly as possible thereafter, Guarantor shall send the Administrative Agent an official receipt showing payment thereof, together with such additional documentary evidence as may be required from time to time by Administrative Agent.

3.14 Reliance on Guaranty. All extensions of credit and financial accommodations heretofore or hereafter made by the Administrative Agent, the Issuing Bank or any Lender under or in respect of the Credit Agreement or any of the other Loan Documents shall be conclusively presumed to have been made in reliance on and acceptance of this Guaranty.

ARTICLE IV

In order to induce the Administrative Agent, the Issuing Bank and the Lenders to accept and rely on this Guaranty, Guarantor warrants and represents to the Administrative Agent, the Issuing Bank and each Lender as follows:

4.1 Relationship to the Borrowers. Guarantor has determined that its liability and obligation under this Guaranty may reasonably be expected to substantially benefit it directly or indirectly, and its board of directors (or such board’s duly authorized and appointed designee) or other equivalent body has made that determination. The transactions contemplated in this Guaranty produce distinct and identifiable financial and economic direct or indirect benefits to Guarantor. Such identifiable benefits include: (a) the availability to Guarantor of the proceeds of the Loans on an as-needed basis by way of intercompany loans and/or capital contribu¬tions for general corporate or other purposes, and (b) the general improvement of Guarantor’s financial and economic condition. Guarantor has had full and complete access to the underlying papers relating to the Obligations and all other papers executed by the Borrowers or any other Person in connection with the Obligations, has reviewed them and is fully aware of the meaning and effect of their contents. Guarantor is fully informed of all circumstances which bear upon the risks of executing this Guaranty and which a diligent inquiry would reveal. Guarantor has adequate means to obtain from the Borrowers on a continuing basis information concerning the Borrowers’ financial condition, and is not depending on the Administrative Agent, the Issuing Bank or any Lender to provide such information, now or in the future. Guarantor agrees that neither the Administrative Agent, the Issuing Bank nor any Lender shall have any obligation to advise or notify it or to provide it with any data or information. The execution and delivery of this Guaranty is not a condition precedent (and neither the Administrative Agent, the Issuing Bank nor any Lender has in any way implied that the execution of this Guaranty is a condition precedent) to the making, extending or modifying of any loan or any other financial accommodation to or for Guarantor.

4.2 Guarantor Solvent. Guarantor is now Solvent, and no bankruptcy or insolvency proceedings are pending or contemplated by or – to the best of Guarantor’s knowledge – against Guarantor. Guarantor’s liabilities and obligations under this Guaranty do not and will not render Guarantor not Solvent, cause Guarantor’s liabilities to exceed Guarantor’s assets or leave Guarantor with too little capital to properly conduct all of its business as now conducted or contemplated to be conducted.

Guarantor shall not accept any payment on any indebtedness of either or both Borrowers or any of their respective Subsidiaries or any other Obligor until the termination of this Guaranty, shall in no circumstance whatsoever attempt to set-off or reduce any obligations because of such indebtedness and shall, if the Administrative Agent shall so request, collect and receive such indebtedness as trustee for the Administrative Agent, the Issuing Bank and the Lenders and pay over all sums so collected to the Administrative Agent for the account of the Issuing Bank and the Lenders on account of the Obligations but without reducing or affecting in any manner the liability of Guarantor under this Guaranty.

6.6 “Including” is Not Limiting; Section Headings. Wherever the term “including” or a similar term is used in this Guaranty, it shall be read as if it were written “including by way of example only and without in any way limiting the generality of the clause or concept referred to.” The headings used in this Guaranty are included for reference only and shall not be considered in interpreting, applying or enforcing this Guaranty.

(c) Guarantor 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 action or proceeding arising out of or relating to this Guaranty in any court referred to in paragraph (b) of this Section. Guarantor 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.

Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ notice to Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Pledged Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

Any surplus of such cash or cash proceeds and interest accrued thereon, if any, held by the Administrative Agent and remaining after payment in full of all the Obligations shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus; provided that the Administrative Agent shall have no obligation to invest or otherwise pay interest on any amounts held by it in connection with or pursuant to this Agreement.

SECTION 13. Registration Rights, Private Sales, Etc.

(a) If the Administrative Agent shall determine to exercise its and the other Secured Parties’ right to sell all or any of the Pledged Collateral pursuant to Section 12, Pledgor agrees that, upon request of the Administrative Agent, Pledgor will cause the officers and directors of each Issuer of the Shares it has pledged, at its expense, to cooperate fully with the Administrative Agent in conformity with requirements imposed by law for the availability of an exemption from registration under the Securities Act of 1933, as amended from time to time (the “Securities Act”), and if the Administrative Agent shall determine that such exemption is not reasonably available for such sale, Pledgor shall use its reasonable efforts to:

(i) execute and deliver, and cause the Issuer of the Pledged Collateral contemplated to be sold and the directors and officers thereof to execute and deliver, all such instruments and documents, and to use its reasonable efforts to do or cause to be done all such other acts and things, as may be necessary in the reasonable opinion of the Administrative Agent to effectively realize upon the value of such Pledged Collateral, to register such Pledged Collateral under the provisions of the Securities Act, or the securities laws of any relevant jurisdiction outside the United States, to use its reasonable efforts to cause the registration statement relating thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished to facilitate the sale or other disposition of such Pledged Collateral, or that portion thereof to be sold, and to make all amendments and supplements thereto and to the related prospectuses which, in the opinion of the Administrative Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act, and the rules and regulations of the Securities Act, and the rules and regulations of the Securities and Exchange Commission, applicable thereto or, where relevant, the laws, sales and regulations of such other jurisdiction applicable thereto;

(ii) qualify the Pledged Collateral pledged by it hereunder under the state securities or “Blue Sky” laws, if applicable thereto, and to obtain all necessary governmental approvals for the sale of such Pledged Collateral, as requested by the Administrative Agent;

(iii) cause the Issuer of the Pledged Collateral to make available to its security holders, as soon as practicable, an earnings statement which will satisfy the provisions of Section 11(a) of the Securities Act; and

(iv) do or cause to be done all such other acts and things as reasonably may be necessary to make such sale of the Pledged Collateral or any part thereof valid and binding and in compliance with applicable law.

(b) Pledgor recognizes that the Administrative Agent may be unable to effect a public sale of any or all of the Pledged Collateral by reason of certain prohibitions contained in the laws of any jurisdiction outside the United States or in the Securities Act and applicable state securities laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Pledged Collateral for their own account for investment and not with a view to the distribution or resale thereof. Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall, to the extent permitted by law, not be deemed to have been made in a commercially unreasonable manner solely by reason of such lesser prices or favorable terms. Neither the Administrative Agent nor the other Secured Parties shall be under any obligation to delay a sale of any of the Pledged Collateral for the period of time necessary to permit the Issuer of such securities to register such securities under the laws of any jurisdiction outside the United States, under the Securities Act or under any applicable state securities laws, even if the Issuer would agree to do so.

(c) Pledgor further agrees to do or cause to be done, to the extent that Pledgor may legally do so, all such other acts and things as reasonably may be necessary to make such sales or resales of any portion or all of the Pledged Collateral pledged by it valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at Pledgor’s expense. Pledgor further agrees that a breach by it of any of the covenants contained in this Section 13 will cause irreparable injury to the Administrative Agent and the other Secured Parties, and that the Administrative Agent and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, agrees that each and every covenant contained in this Section 13 shall be specifically enforceable against Pledgor, and Pledgor hereby WAIVES and agrees, to the fullest extent permitted by law, not to assert as a defense against an action for specific performance of such covenants that (i) Pledgor’s failure to perform such covenants will not cause irreparable injury to the Administrative Agent or the other Secured Parties, or (ii) the Administrative Agent or the other Secured Parties have an adequate remedy at law in respect of such breach, or (iii) any other defense, except for a defense that no Event of Default has occurred. Pledgor further acknowledges the impossibility of ascertaining the amount of damages which would be suffered by the Administrative Agent and the other Secured Parties by reason of a breach of any of the covenants contained in this Section 13 and, consequently, agrees that, if Pledgor shall breach any of such covenants and the Administrative Agent or any other Secured Party shall ▇▇▇ for damages for such breach, Pledgor shall pay to the Administrative Agent or such Secured Party, as liquidated damages and not as a penalty, an aggregate amount equal to the value of the Pledged Collateral on the date the Administrative Agent or such Secured Party shall demand compliance with this Section 13.

(d) To the fullest extent permitted by applicable law and subject to, and to the extent not inconsistent with, the provisions of Section 9.03 of the Credit Agreement, Pledgor agrees to indemnify, protect and save harmless the Administrative Agent, the other Secured Parties and any controlling persons thereof (within the meaning of the Securities Act) from and against any and all liabilities, suits, claims, costs and expenses (including counsel fees and disbursements) arising under the Securities Act, the Exchange Act or at common law, or pursuant to any other applicable law in connection with the aforesaid registration of Pledged Collateral pledged by it, insofar as such liabilities, suits, claims, costs and expenses arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the aforesaid registration statement, or the aforesaid registration statement as amended or supplemented, or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that Pledgor shall not be liable in any such case to the extent that any such liabilities, suits, claims, costs and expenses arise out of, or are based upon, the gross negligence or the willful misconduct of the Administrative Agent or any Secured Party or any untrue statement or alleged untrue statement or omission or alleged omission made in the aforesaid registration statement or the aforesaid registration statement as amended or supplemented, in reliance upon and in conformity with written information furnished to Pledgor by the Administrative Agent or such other Secured Party specifically for inclusion therein. The foregoing indemnity agreement is in addition to any liability that Pledgor may otherwise have to the Administrative Agent and any such other Secured Party, or any such controlling person.

SECTION 14. Interest. Pledgor agrees to pay interest on any expenses or other sums due to the Administrative Agent and the other Secured Parties hereunder that are not paid when due at a rate per annum equal to the lesser of (i) the Highest Lawful Rate or (ii) 2% above the Alternate Base Rate.

SECTION 15. Amendments, Etc. No amendment or waiver of any provision of this Agreement nor consent to any departure by Pledgor herefrom shall in any event be effective unless the same shall be in writing and signed by the Required Lenders, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 16. Addresses for Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by facsimile, if to Pledgor, addressed to it at the address of the Borrower specified in Section 9.01 of the Credit Agreement, and if to the Administrative Agent, addressed to it at the address of the Administrative Agent specified in Section 9.01 of the Credit Agreement, or as to each party at such other address as shall be designated by such party in a written notice to each other party complying as to delivery with the terms of this Section 16. All such notices and communications shall, when personally delivered, delivered by courier, mailed or transmitted by telecopy, become effective (i) if personally delivered or delivered by courier, when received; (ii) if by mail, three (3) Business Days after such notice or other communication was deposited in the mail by certified mail, return receipt requested (with postage prepaid and addressed as aforesaid), or (iii) when sent by telecopy, when transmitted to the correct telecopier, with confirmation received. Notices and other communications to the Secured Parties hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent. The Administrative Agent or the Pledgor 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. Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement) and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient, at its e-mail address as described in the foregoing clause (i), of notification that such notice or communication is available and identifying the website address therefor; provided that, for both clauses (i) and (ii) above, if such notice, email or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient.

SECTION 17. Security Interest Absolute. All rights of the Administrative Agent and the other Secured Parties, all obligations of Pledgor hereunder and the security interest hereunder shall, to the extent permitted by applicable law, be absolute and unconditional, irrespective of:

(a) any lack of validity or enforceability of the Credit Agreement, the Letters of Credit or any of the other Loan Documents executed in connection with the Credit Agreement;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations or any other amendment or waiver of or any consent to any departure from the Credit Agreement, the Letters of Credit or any of the other Loan Documents executed in connection with the Credit Agreement;

(c) any exchange, release or nonperfection of any other collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Obligations; or

(d) any other circumstance (other than payment in full of the Obligations) which might otherwise constitute a defense available to, or a discharge of, Pledgor, any Guarantor or any Subsidiary that is a party to any Loan Document executed in connection with the Credit Agreement.

SECTION 18. Continuing Security Interest. This Agreement and the delivery of the Pledged Collateral to the Administrative Agent shall create a continuing security interest in the Pledged Collateral as security for the Obligations and shall (a) remain in full force and effect until the expiration or termination of the Letters of Credit and the Commitments and the indefeasible payment in full thereafter of the Obligations; (b) be binding upon Pledgor and its successors and assigns; and (c) inure to the benefit of the Administrative Agent, the other Secured Parties and their respective successors and permitted assigns. Without limiting the generality of the foregoing clause (c), the Administrative Agent and the Lenders may, subject to Section 9.04 of the Credit Agreement, assign or otherwise transfer any of their respective rights under this Agreement to any other Person, and such Person shall thereupon become vested with all the benefits in respect thereof granted herein or otherwise to the Administrative Agent or the Lenders, as the case may be. Upon the expiration or termination of the Letters of Credit and the Commitments and the indefeasible payment in full thereafter of the Obligations, Pledgor shall be entitled to the return, upon its request and at its expense, of such of the Pledged Collateral as shall not have been sold or otherwise applied pursuant to the terms hereof. Upon the release of any Pledged Collateral as provided in Section 9.18 of the Credit Agreement, Pledgor shall be entitled to the return, upon its request and at its expense, of such Pledged Collateral.

SECTION 19. Waiver of Marshalling. All rights of marshalling of assets of Pledgor, including any such right with respect to the Pledged Collateral, are hereby waived by Pledgor.

SECTION 20. Limitation by Law. All rights, remedies and powers provided in this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Agreement invalid, unenforceable, in whole or in part, or not entitled to be recorded, registered or filed under the provisions of any applicable law.

SECTION 21. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Should any clause, sentence, paragraph, subsection or Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom by the parties hereto, and the remainder will have the same force and effectiveness as if such stricken part or parts had never been included herein.

SECTION 22. Captions. The captions in this Agreement have been inserted for convenience only and shall be given no substantive meaning or significance whatever in construing the terms and provisions of this Agreement.

SECTION 23. No Waiver; Remedies. No failure on the part of the Administrative Agent or any other Secured Party to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 24. Execution in Counterparts. This Agreement may be executed in any number of counterparts, by different parties hereto in separate counterparts and by telecopy facsimile, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. This Agreement may be executed and delivered by facsimile or other form of electronic transmission (for example, .pdf).

SECTION 25. Survival of Representations and Warranties. All representations and warranties contained in this Agreement or made in writing by or on behalf of Pledgor in connection herewith, shall survive the execution and delivery of this Agreement and shall continue until 365 or 366 days, as the case may be, after the repayment of the Obligations and the expiration of the Letters of Credit. Any investigation by the Administrative Agent or any other Secured Party shall not diminish in any respect whatsoever its right to rely on such representations and warranties.

SECTION 26. Governing Law; Jurisdiction; Waiver of Jury Trial, Etc.

(a) THIS AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

(c) NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS AGREEMENT SHALL AFFECT ANY RIGHT THAT THE SECURED PARTIES OR ADMINISTRATIVE AGENT MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AGAINST THE PLEDGORS OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

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 ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON 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 27. Duty of Administrative Agent. The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Pledged Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account. To the fullest extent provided by applicable law, neither the Administrative Agent, any other Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Pledged Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Pledged Collateral upon the request of Pledgor or any other Person or to take any other action whatsoever with regard to the Pledged Collateral or any part thereof. The powers conferred on the Administrative Agent and the other Secured Parties hereunder are solely to protect the Administrative Agent’s and the other Secured Parties’ interests in the Pledged Collateral and shall not impose any duty upon the Administrative Agent or any other Secured Party to exercise any such powers. The Administrative Agent and the other Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to Pledgor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

SECTION 28. Financing Statements. Pursuant to any applicable law, Pledgor authorizes the Administrative Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Pledged Collateral in such form and in such offices as the Administrative Agent reasonably determines appropriate to perfect the security interests of the Administrative Agent under this Agreement. Pledgor hereby ratifies and authorizes the filing by the Administrative Agent of any financing statement with respect to the Pledged Collateral made prior to the date hereof.

SECTION 29. Authority of Administrative Agent. Pledgor acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Pledgor, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and Pledgor shall not be under any obligation, or entitlement, to make any inquiry respecting such authority.

SECTION 30. Additional Pledgors. Each Material Subsidiary of the Borrower that is required to become a party to this Agreement pursuant to Section 5.17 of the Credit Agreement shall become a Pledgor for all purposes of this Agreement upon execution and delivery by such Subsidiary of a Pledge Agreement Supplement in the form of Annex 1 hereto.

Section 2.3 Perfection and Protection of Security Interest.

(1) Each Grantor shall, at its expense, perform all steps requested by the Administrative Agent at any time to ensure the attachment, perfection and first priority of, and the Administrative Agent’s ability to enforce, the Administrative Agent’s Liens, including: (i) executing and filing amendments to financing statements in form and substance satisfactory to the Administrative Agent; (ii) delivering to the Administrative Agent warehouse receipts covering any portion of the Collateral located in warehouses and for which warehouse receipts are issued and certificates of title covering any portion of the Collateral (other than Excluded Assets) for which certificates of title have been issued (and, if requested by the Administrative Agent, causing the Administrative Agent’s name to be noted thereon); (iii) complying with any provision of any statute, regulation or treaty of the United States as to any Collateral if compliance with such provision is a condition to attachment, perfection of, or Administrative Agent’s ability to enforce, Administrative Agent’s security interest in such Collateral, (iv) obtaining any and all necessary governmental and other third party consents and approvals, including, without limitation, any consent of any licensor, lessor or other person obligated on Collateral; (v) obtaining executed landlord’s waivers or subordination agreements in form and substance satisfactory to the Administrative Agent, executed by the lessor of each leased location in which at any time Collateral valued at $500,000 or more is maintained, held or stored, subordinating the Liens held by such lessor to the Liens of the Administrative Agent on behalf of the Secured Parties; and (vi) taking such other steps as are deemed necessary or desirable by the Administrative Agent to maintain and protect the Administrative Agent’s Liens. Each Grantor agrees that a carbon, photographic, photostatic, or other reproduction of this Agreement or of a financing statement is sufficient as a financing statement.

(2) Each Grantor will promptly, at any time and from time to time, at its sole expense, execute and deliver to the Administrative Agent such further instruments and documents, and take such further action, as the Administrative Agent may from time to time reasonably request in order to carry out to establish and protect the rights, interests and remedies created, or intended to be created, in favor of the Administrative Agent and the other Secured Parties. The Grantors, jointly and severally, will pay, or reimburse the Administrative Agent for paying, any and all fees, costs and expenses of whatever kind or nature incurred in connection with the creation, preservation and protection of the Administrative Agent’s Lien on the Collateral, including all fees and taxes in connection with the recording or filing of instruments and documents in public offices, payments or discharges of Taxes or Liens upon or in respect of the Collateral, premiums for insurance required to be obtained hereunder with respect to the Collateral and all other fees, costs and expenses in connection with protecting, maintaining or preserving the Collateral and the interests of the Administrative Agent and the other Secured Parties, whether through judicial proceedings or otherwise, or in connection with defending or prosecuting any actions, suits or proceedings arising out of or related to the Collateral; and all such amounts that are paid by the Administrative Agent shall, until reimbursed by such Grantor, constitute Obligations secured by the Collateral.

(3) Unless the Administrative Agent shall otherwise consent in writing (which consent may be revoked in the Administrative Agent’s discretion), each Grantor shall deliver to the Administrative Agent all Collateral consisting of negotiable Documents, Chattel Paper, and Instruments promptly after such Grantor receives the same.

(4) Each Grantor shall obtain and deliver to the Administrative Agent landlord’s waivers or subordination agreements in form and substance satisfactory to the Administrative Agent, executed by the lessor of each leased location in which at any time Collateral valued at $500,000 or more is maintained, held or stored, subordinating the Liens held by such lessor to the Liens of the Administrative Agent on behalf of the Secured Parties. Upon request by the Administrative Agent, each Grantor shall in all instances obtain a signed acknowledgment of the Administrative Agent’s Liens from each bailee having possession of any Collateral that such bailee holds such Collateral for the benefit of the Secured Parties

(5) If any Grantor, at any time, holds or acquires an interest in any electronic chattel paper or any “transferrable record”, as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, such Grantor shall notify the Administrative Agent thereof and, upon the occurrence and continuance of an Event of Default, shall take such action as the Administrative Agent may reasonably request to vest in the Administrative Agent’s control, under Section 9-105 of the UCC, such electronic chattel paper or control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record.

(6) All Deposit Accounts of each Grantor are listed on Schedule 2.3a. For each Deposit Account that any Grantor at any time opens or maintains, such Grantor shall, at the Administrative Agent’s request and option, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, either (a) cause the depositary bank to comply at any time with instructions from the Administrative Agent to such depositary bank directing the disposition of funds from time to time credited to such deposit account, without further consent of such Grantor, or (b) arrange for the Administrative Agent to become the customer of the depositary bank with respect to the deposit account, with such Grantor being permitted, only with the consent of the Administrative Agent, to exercise rights to withdraw funds from such deposit account.

(7) All Securities Accounts of each Grantor are listed on Schedule 2.3b. For each Securities Account that any Grantor at any time opens or maintains, such Grantor shall notify the Administrative Agent thereof and, at the Administrative Agent’s request and option, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, either (a) cause the securities intermediary to comply at any time with instructions from the Administrative Agent to such securities intermediary directing the disposition of securities and security entitlements from time to time held in such securities account, without further consent of such Grantor, or (b) arrange for the Administrative Agent to become the customer of the securities intermediary with respect to the securities account.

(8) If any Grantor shall at any time hold or acquire any certificated securities, such Grantor shall forthwith endorse, assign and deliver the same to the Administrative Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Administrative Agent may from time to time specify. If any securities now or hereafter acquired by any Grantor are uncertificated and are issued to any Grantor or its nominee directly by the issuer thereof, such Grantor shall immediately notify the Administrative Agent thereof and, at the Administrative Agent’s request and option, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, either (a) cause the issuer to agree to comply with instructions from the Administrative Agent as to such securities, without further consent of such Grantor or such nominee, or (b) arrange for the Administrative Agent to become the registered owner of the securities. If any securities, whether certificated or uncertificated, or other investment property now or hereafter acquired by any Grantor are held by such Grantor or its nominee through a securities intermediary or commodity intermediary, such Grantor shall immediately notify the Administrative Agent thereof and, at the Administrative Agent’s request and option, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, either (i) cause such securities intermediary or (as the case may be) commodity intermediary to agree to comply with entitlement orders or other instructions from the Administrative Agent to such securities intermediary as to such securities or other investment property, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Administrative Agent to such commodity intermediary, in each case without further consent of such Grantor or such nominee, or (ii) in the case of financial assets or other investment property held through a securities intermediary, arrange for the Administrative Agent to become the entitlement holder with respect to such investment property, with such Grantor being permitted, only with the consent of the Administrative Agent, to exercise rights to withdraw or otherwise deal with such investment property.

(9) If any Collateral is at any time in the possession of a bailee, the relevant Grantor shall promptly notify the Administrative Agent thereof and, at the Administrative Agent’s request and option, shall promptly obtain an acknowledgement from the bailee, in form and substance satisfactory to the Administrative Agent, that the bailee holds such Collateral for the benefit of the Administrative Agent, and that such bailee agrees to comply, without further consent of such Grantor, with instructions from the Administrative Agent as to such Collateral.

(10) Each Grantor hereby irrevocably authorizes the Administrative Agent at any time and from time to time to file as valid financing statements in any filing office or in the applicable financing statement records any financing statements and amendments thereto that (a) indicate the Collateral (i) as “all assets” or “all personal property” of such Grantor, or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC, or (ii) as being of an equal or lesser scope or with greater detail, and (b) contain any other information required by Part 5 of Article 9 of the UCC for the sufficiency or filing office acceptance of any financing statement or amendment, including whether such Grantor is an organization, the type of organization, and any organization identification number issued to such Grantor. Each Grantor agrees to furnish any such information to the Administrative Agent promptly upon request. Each Grantor also ratifies its authorization for the Administrative Agent to file any like financing statements or amendments thereto if filed prior to the date hereof. Upon such filing, no filing or recording of any other financing statements or other instrument and no recording, filing or indexing of this Agreement is necessary in order to preserve and protect the Administrative Agent’s security interest in the Collateral as a legal, valid, enforceable and perfected (to such extent) security interest in the Collateral, except filing of appropriate continuation statements with respect to such UCC financing statement. No person or entity from which any Grantor leases any of its premises has filed any UCC financing statement with respect to any contractual lien that would have priority over the Administrative Agent’s security interest in the Collateral.

(11) On the date hereof and at any time during the term of this Agreement during which a security interest in the Administrative Agent’s favor in the Collateral exists, no financing statement (or similar statement or instrument of registration under the laws of any jurisdiction) is or will be on file or registered in any public office covering any interest of any kind with respect to the Collateral (other than those covering Permitted Encumbrances), or intended so to be, other than those relating to the security interest created by this Agreement or those which may have been consented to by the Administrative Agent in writing, and the applicable Grantor will be the lawful owner of the Collateral and will have good right to grant the Administrative Agent a security interest therein.

(12) From time to time, each Grantor shall, upon the Administrative Agent’s request, execute and deliver confirmatory written instruments pledging to the Administrative Agent, for the benefit of the Secured Parties, the Collateral, but any Grantor’s failure to do so shall not affect or limit any security interest or any other rights of the Administrative Agent in and to the Collateral with respect to such Grantor. Until all Secured Obligations have been fully satisfied, the Administrative Agent’s Liens shall continue in full force and effect in all Collateral.

(13) No Grantor shall, without the prior written consent of the Administrative Agent, (i) change its type of entity; (ii) change its legal name, whether by amendment of its organizational documents, by reorganization or otherwise; (iii) change its organizational identification number; (iv) reincorporate or reorganize itself under the laws of any jurisdiction; (v) enter into any proceedings for (A) any merger, consolidation, conversion, dissolution, liquidation or termination, or (B) any transfer to or domestication in any other jurisdiction; or (vi) change its location (within the meaning of Section 9-307 of the UCC).

(14) Each Grantor acknowledges that it is not authorized to file or to consent to the filing of any financing statement or amendment or termination statement with respect to any financing statement without the prior written consent of the Administrative Agent and agrees that it will not do so without the prior written consent of the Administrative Agent, subject to such Grantor’s rights under Section 9-509(d)(2) of the UCC.

(15) No Grantor shall enter into any agreement that restricts or prohibits the grant of a security interest in Accounts, Inventory, Chattel Paper, Instruments, Investment Property, payment intangibles, or any other types of Collateral or the proceeds of any of foregoing to the Administrative Agent.

Section 2.4 Location of Collateral.

(a) Each Grantor represents and warrants to the Administrative Agent that (a) Schedule 2.4 is a correct and complete list of the location of such Grantor’s chief executive office, the location of its books and records, the locations of the Collateral, and the locations of all of its other places of business and (b) Schedule 2.4 correctly sets forth the names of the owners and lessors or sublessors of such facilities and locations.

Without limiting the foregoing, each Grantor represents that all of its Inventory (other than Inventory in transit) is, and covenants that all of its Inventory will be, located either (A) on premises owned by such Grantor, (B) on premises leased by such Grantor, provided that the Administrative Agent has received, if requested by the Administrative Agent, an executed landlord waiver from the landlord of such premises in form and substance satisfactory to the Administrative Agent, or (C) in a warehouse or with a bailee, provided that the Administrative Agent has received an executed bailee letter from the applicable Person in form and substance satisfactory to the Administrative Agent.

(b) Each Grantor will further furnish to the Administrative Agent at such times as the Administrative Agent may reasonably request the location and aggregate value at each such location of all such Grantor’s Inventory and a statement showing opening Inventory, Inventory acquired, Inventory sold and held for future delivery, Inventory returned or repossessed, Inventory used or consumed in such Grantor’s business and closing Inventory, such statement to be certified by such Grantor’s chief financial officer. The Administrative Agent shall have the right at any time and from time to time to verify the existence and state of the Collateral in any manner as the Administrative Agent may consider appropriate, and each Grantor agrees to furnish all assistance and information and to perform all such acts as the Administrative Agent may reasonably request in connection therewith and for such purpose to grant to the Administrative Agent or its agents reasonable access to all places where the Collateral may be located and to all premises occupied by such Grantor’s business.

Such insurance shall be in such minimum amounts that such Grantor will not be deemed a co-insurer under applicable insurance laws, regulations and policies and otherwise shall be in such amounts, contain such terms, be in such forms and be for such periods as may be reasonably satisfactory to the Administrative Agent. In addition, all such insurance shall be payable to the Administrative Agent as loss payee under a standard loss payee clause. Without limiting the foregoing, such Grantor will (i) keep all of its physical property insured with casualty or physical hazard insurance on an “all risks” basis, with broad form flood coverage and electronic data processing coverage, with a full replacement cost endorsement and an “agreed amount” clause in an amount equal to 100% of the full replacement cost of such property, (ii) maintain all such workers’ compensation or similar insurance as may be required by law, and (iii) maintain, in amounts and with deductibles equal to those generally maintained by businesses engaged in similar activities in similar geographic areas, general public liability insurance against claims of bodily injury, death or property damage occurring, on, in or about the properties of such Grantor.

The proceeds of any casualty insurance in respect of any casualty loss of any of the Collateral shall, subject to the rights, if any, of other parties with an interest having priority in the property covered thereby, (i) so long as no Event of Default has occurred and is continuing, be disbursed to the relevant Grantor for direct application by such Grantor solely to the repair or replacement of such Grantor’s property so damaged or destroyed, and (ii) if an Event of Default has occurred, be held by the Administrative Agent as cash collateral for the Secured Obligations or be applied by the Administrative Agent to the Secured Obligations.

(a) Continuation of Insurance. All policies of insurance shall provide for at least thirty (30) days’ prior written notice to the Administrative Agent of any cancellation or material change in coverage.

Each Grantor shall furnish the Administrative Agent with certificates of insurance and policies evidencing compliance with the foregoing insurance provision.

Section 2.8 Appraisals. Whenever an Event of Default exists, each Grantor shall, at its expense and upon the Administrative Agent’s request, provide the Administrative Agent with appraisals or updates thereof of any or all of the Collateral consisting of Equipment from a credentialed appraiser acceptable to the Administrative Agent, and prepared on a basis and in form, satisfactory to the Administrative Agent, such appraisals and updates to include, without limitation, information required by applicable law and regulation and by the internal policies of the Administrative Agent.

Section 2.9 Access and Examination.

Each Grantor will deliver to the Administrative Agent any instrument necessary for the Administrative Agent to obtain records from any service bureau maintaining records for such Grantor. The Administrative Agent may at any time when an Event of Default exists and at such Grantor’s expense make copies of all of any Grantor’s books and records, or require such Grantor to deliver such copies to the Administrative Agent.

The Administrative Agent shall have the right, at any time, in the Administrative Agent’s name or in the name of a nominee of the Administrative Agent, to verify the validity, amount, or any other matter relating to the Accounts, Inventory, or other Collateral, by mail, telephone, or otherwise.

Section 2.10 Accounts.

(a) Each Grantor hereby represents and warrants to the Administrative Agent, with respect to such Grantor’s Accounts, that each existing Account represents, and each future Account will represent, a bona fide sale or lease and delivery of goods by such Grantor, or rendition of services by such Grantor, in the ordinary course of such Grantor’s business.

(b) None of the Account Debtors or other persons obligated on any of the Accounts is a governmental authority covered by the Federal Assignment of Claims Act or like federal, state or local statute or rule in respect of such Collateral.

(c) Each of Grantor’s accounts receivable: (A) subject to any reserve reflected on Lufkin’s balance sheet, is on the date hereof and will be at all times during the term of this Agreement a good and valid account receivable representing an undisputed bona fide right to payment from the Account Debtor with respect thereto for merchandise held subject to delivery or theretofore shipped or delivered pursuant to a contract of sale, for services theretofore performed by such Grantor, for property sold, leased, licensed, assigned or otherwise disposed of or arising out of the use of a credit or charge card or information contained on or for use with the card; (B) will not be subject to any defense, offset, counterclaim, holdback, discount or allowance, except as stated in a statement delivered to the Administrative Agent pursuant to this subsection (c) or as would not reasonably be likely to result in a Material Adverse Effect; (C) will not have been made with an Account Debtor under an agreement pursuant to which any material reduction or discount may be claimed except as indicated in a statement or invoice furnished to the Administrative Agent with reference thereto; and (D) will be an account receivable of which such Grantor is the lawful owner and has the right to subject the same to the Administrative Agent’s Lien and no action has been or will be taken by such Grantor which has or will have the effect of giving to an Account Debtor any defense, setoff, claim or counterclaim against any Grantor that may be asserted against the Administrative Agent, whether in any proceeding to enforce the Collateral or otherwise. Any variance from the representations set forth in this subsection (c) with respect to any account receivable will be noted on any report or statement of account receivables delivered to the Administrative Agent or will be otherwise be reported in writing to the Administrative Agent promptly upon such Grantor’s becoming aware of such variance. No account receivable will have been or hereafter will be sold, assigned or transferred to any person or entity other than the Administrative Agent or in any way encumbered except to the Administrative Agent.

(d) Each Grantor will perform all of the terms, covenants and conditions on such Grantor’s part to be observed or performed under the contracts giving rise to such Grantor’s accounts receivable and other Accounts and take all steps necessary to keep such licenses and contracts in full force and effect, except to the extent that failure to do so is not reasonably likely to result in a Material Adverse Effect.

The Administrative Agent shall not be obligated to do any of the acts authorized in this Agreement, but if the Administrative Agent elects to do any such act, the Administrative Agent will not be responsible to any Grantor except for the Administrative Agent’s own gross negligence or willful misconduct. During the existence of any Event of Default, the Administrative Agent may (but shall not be required to), without notice to or consent from any Grantor, ▇▇▇ upon or otherwise collect, extend the time for payment of, modify or amend the terms of, compromise or settle for cash, credit, or otherwise upon any terms, grant other indulgences, extensions, renewals, compositions, or releases, and take or omit to take any other action with respect to the Collateral, any security therefor, any agreement relating thereto, any insurance applicable thereto, or any Person liable directly or indirectly in connection with any of the foregoing, without discharging or otherwise affecting the liability of any Grantor for the Secured Obligations.

(b) It is expressly agreed by each Grantor that, anything herein to the contrary notwithstanding, such Grantor shall remain liable under each of its contracts and each of its licenses to observe and perform all the conditions and obligations to be observed and performed by it thereunder.

(c) The Administrative Agent may at any time during the existence of an Event of Default, without prior notice to any Grantor, notify Account Debtors and other Persons obligated on the Collateral that the Administrative Agent has a security interest therein and that payments shall be made directly to the Administrative Agent on behalf of the Secured Parties. Upon the request of the Administrative Agent, any Grantor shall so notify Account Debtors and other Persons obligated on Collateral. Once any such notice has been given to any Account Debtor or other Person obligated on the Collateral, no Grantor shall give any contrary instructions to such Account Debtor or other Person without the Administrative Agent’s prior written consent.

Any amount to be paid under this Section by the Grantors to any Indemnitee shall be a demand obligation owing by the Grantors to the Indemnitee and shall bear interest from the date of expenditure until paid at the Default Rate. The obligations of the Grantors under this Section 2.19 shall survive the termination of this Agreement.

Section 2.22 Remedies: Rights upon Default.

(a) In addition to all other rights and remedies granted to it under this Agreement and under any other instrument or agreement securing, evidencing, or relating to any of the Obligations or the Secured Obligations, if any Event of Default shall exist, the Administrative Agent may exercise all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, each Grantor expressly agrees that in any such event the Administrative Agent, without demand of performance or other demand, advertisement, or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon any Grantor or any other Person (all and each of which demands, advertisements, and notices are hereby expressly WAIVED to the maximum extent permitted by the UCC and other applicable law), may forthwith enter upon the premises of any Grantor where any Collateral is located through self-help, without judicial process, without first obtaining a final judgment or giving such Grantor or any other Person notice and opportunity for a hearing on the Administrative Agent’s claim or action and may collect, receive, assemble, process, appropriate, and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, license, assign, give an option or options to purchase, or sell or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at a public or private sale or sales, at any exchange at such prices as the Administrative Agent may deem acceptable, for cash or on credit or for future delivery without assumption of any credit risk. The Administrative Agent shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase for the benefit of the Administrative Agent, the whole or any part of said Collateral so sold, free of any right or equity of redemption, to the extent permitted by law, which equity of redemption each Grantor hereby releases. Such sales may be adjourned and continued from time to time with or without notice. The Administrative Agent shall have the right to conduct such sales on any Grantor’s premises or elsewhere and shall have the right to use each Grantor’s premises without charge for such time or times as the Administrative Agent deems necessary or advisable.

(b) Upon any sale of any of the Collateral, whether made under the power of sale given by this Agreement or under judgment, order or decree in any judicial proceeding for foreclosure or involving the enforcement of this Agreement: (i) the Administrative Agent may bid for the property being sold and, upon compliance with the terms of sale, may hold, retain and possess and dispose of such property in its own absolute right without further accountability and may, in paying the purchase price for such property, deliver any notes evidencing the Obligations or claims for interest thereon in lieu of cash in payment of the amount equal to the unpaid amount of such notes or claims; (ii) the Administrative Agent may make and deliver to the purchaser or purchasers a good and sufficient deed, ▇▇▇▇ of sale and instrument of assignment and transfer of the property sold; (iii) the Administrative Agent is irrevocably appointed each Grantor’s true and lawful attorney-in-fact in such Grantor’s name and stead to make all necessary deeds, bills of sale and instruments of assignment and transfer of the property thus sold and for such other purposes as are necessary or desirable to effectuate the provisions of this Agreement, and for that purpose the Administrative Agent may execute and deliver all necessary deeds, bills of sale and instruments of assignment and transfer, and may substitute one or more persons or entities with like power, and each Grantor ratifies and confirms all that such Grantor’s said attorney, or such substitute or substitutes, shall lawfully do by virtue of this appointment, but if so requested by the Administrative Agent or by any purchaser, such Grantor will ratify and confirm any such sale or transfer by executing and delivering to the Administrative Agent or to such purchaser all deeds, bills of sale, instruments of assignment and transfer and releases as may be designated in any such request; (iv) all of any Grantor’s right, title, interest, claim and demand whatsoever, either at law or in equity or otherwise, in and to the property so sold shall be divested, such sale shall be a perpetual bar both at law and in equity against such Grantor, its successors and assigns and against any and all persons or entities claiming or who may claim the property sold or any part thereof from, through or under such Grantor or its successors or assigns; (v) each Grantor will terminate and cease forthwith all use of the property so sold; (vi) the Administrative Agent’s receipt or a receipt of the officer making such sale shall be a sufficient discharge to the purchaser or purchasers at such sale for the purchase money, and such purchaser or purchasers, and such purchaser’s or purchasers’ assigns or personal representatives, shall not, after paying such purchase money and receiving such receipt, be obligated to see to the application of such purchase money or be in any way answerable for any loss, misapplication or non-application thereof; and (vii) to the extent that each Grantor may lawfully do so, such Grantor agrees that it will not at any time insist upon or plead, or in any manner whatsoever claim or take the benefit or advantage of, any appraisement, valuation, stay, extension or redemption law or any law permitting such Grantor to direct the order in which the Collateral or any part thereof shall be sold, now or at any time hereafter in force, that may delay, prevent or otherwise affect the performance or enforcement of this Agreement or the Obligations, and each Grantor expressly WAIVES all benefit or advantage of any such law and agrees that such Grantor will not hinder, delay or impede the execution of any power granted or delegated to the Administrative Agent in this Agreement, but will suffer and permit the execution of every such power as though no such law were in force.

(c) Each Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at a place or places designated by the Administrative Agent which are reasonably convenient to the Administrative Agent and such Grantor, whether at such Grantor’s premises or elsewhere, without cost to the Administrative Agent. Until the Administrative Agent is able to effect a sale, lease, or other disposition of Collateral, the Administrative Agent shall have the right to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving Collateral or its value or for any other purpose deemed appropriate by the Administrative Agent. The Administrative Agent shall have no obligation to any Grantor to maintain or preserve the rights of such Grantor as against third parties with respect to Collateral while Collateral is in the possession of the Administrative Agent. The Administrative Agent may, if it so elects, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Administrative Agent’s remedies (for the benefit of the Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment. The Administrative Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization, or sale to the Secured Obligations as provided in Section 2.26 hereof, and only after so paying over such net proceeds, and after the payment by the Administrative Agent of any other amount required by any provision of law, need the Administrative Agent account for the surplus, if any, to any Grantor. To the maximum extent permitted by applicable law, each Grantor waives all claims, damages, and demands against the Administrative Agent arising out of the repossession, retention, or sale of the Collateral except such as arise solely out of the gross negligence or willful misconduct of the Administrative Agent as finally determined by a court of competent jurisdiction. Each Grantor agrees that ten (10) days’ prior notice by the Administrative Agent of the time and place of any public sale or of the time after which a private sale may take place is reasonable notification of such matters, except that, if the Administrative Agent determines in its sole discretion that any of the Collateral is perishable or threatens to decline speedily in value, any such sale may be made on three days’ written notice to such Grantor. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay all Secured Obligations, including any attorneys’ fees or other expenses incurred by the Administrative Agent to collect such deficiency.

(d) Except as otherwise specifically provided herein, each Grantor hereby waives notice of acceptance of this Agreement, notice of nonpayment of any of each Grantor’s Accounts, presentment, demand, protest, and notice thereof with respect to any and all instruments, notice of Collateral received or delivered or any other action taken in reliance of this Agreement and all other demands and notices of any description (to the maximum extent permitted by applicable law) of any kind in connection with this Agreement or any Collateral.

(e) To the extent that applicable law imposes duties on the Administrative Agent to exercise remedies in a commercially reasonable manner, each Grantor acknowledges and agrees that it is not commercially unreasonable for the Administrative Agent (i) to fail to incur expenses reasonably deemed significant by the Administrative Agent to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as the Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession, or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Administrative Agent against risks of loss, collection, or disposition of Collateral or to provide to the Administrative Agent a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by the Administrative Agent, to obtain the services of other brokers, investment bankers, consultants, and other professionals to assist the Administrative Agent in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 2.22(e) is to provide non-exhaustive indications of what actions or omissions by the Administrative Agent would not be commercially unreasonable in the Administrative Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Administrative Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 2.22(e). Without limitation upon the foregoing, nothing contained in this Section 2.22(e) shall be construed to grant any rights to any Grantor or to impose any duties on the Administrative Agent that would not have been granted or imposed by this Agreement or by Requirements of Law in the absence of this Section 2.22(e).

(f) After an Event of Default, no Grantor will request or receive any monies constituting income from or interest on the Collateral, and if any Grantor receives any such monies without any request by such Grantor, such Grantor will pay such monies promptly to the Administrative Agent and such payment shall be applied by the Administrative Agent to satisfy the Obligations.

(g) Each Grantor further acknowledges that any payments on, or other proceeds of, the Collateral received by it from Account Debtors after notification to Account Debtors of the security interest granted by this Agreement and after an Event of Default shall exist, shall be received and held by such Grantor in trust for the Administrative Agent and shall be turned over to the Administrative Agent upon its request to be subject to the provisions of this Agreement.

Section 2.24 Limitation on the Administrative Agent’s Duty in Respect of Collateral. The Administrative Agent shall use reasonable care with respect to the Collateral in its possession or under its control.

Section 2.25 Acknowledgment of Pledge. With respect to any Investment Property issued by a Grantor which at any time is owned by a Grantor and constitutes an uncertificated security as defined by the UCC, such issuing Grantor will comply with instructions originated by the Administrative Agent without further consent by the registered owner thereof.

Each Grantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of such Grantor’s merger or bankruptcy, protest or notice with respect to any notes evidencing the Obligations and all demands whatsoever, and each Grantor agrees that this Agreement will remain in full force and effect so long as any Obligation (other than any contingent indemnity or similar obligation) remains unpaid or unperformed.

Section 3.4 Severability. Whenever possible, each provision of this Agreement shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity without invalidating the remainder of such provision or the remaining provisions of this Agreement.

Section 3.5 No Waiver: Cumulative Remedies. The Administrative Agent shall not by any act, delay, omission, or otherwise be deemed to have waived any of its rights or remedies hereunder, and no waiver shall be valid unless in writing, signed by the Administrative Agent and then only to the extent therein set forth. A waiver by the Administrative Agent of any right or remedy hereunder on anyone occasion shall not be construed as a bar to any right or remedy which the Administrative Agent would otherwise have had on any future occasion. No failure to exercise nor any delay in exercising on the part of the Administrative Agent, any right, power, or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege hereunder preclude any other or future exercise thereof or the exercise of any other right, power or privilege. The rights and remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law. None of the terms or provisions of this Agreement may be waived, altered, modified, or amended except by an instrument in writing, duly executed by the Administrative Agent and the Grantors.

Section 3.6 Grantors’ Obligations Absolute, Etc. The obligations of each Grantor hereunder shall remain in full force and effect without regard to, and shall not be impaired by, (a) any increase in the commitments of the Lenders or the outstanding amount of Obligations under the Credit Agreement or the other Transaction Documents, (b)the lack of validity and enforceability of the Credit Agreement, any of the other Transaction Documents or any other credit facility from the Administrative Agent to any Loan Party; (c) any change in the time, manner or place of payment of, or in any other term of, any of the Obligations or the Secured Obligations or any other amendment or waiver or any consent to any departure from the Credit Agreement, any of the other Transaction Documents or any other credit facility between the Administrative Agent and any other Loan Party; (d) any exchange, release or nonperfection of any of the Collateral or any other collateral securing any of the Obligations or the Secured Obligations, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Secured Obligations; or (e) any other circumstance which might otherwise constitute a defense available to, or discharge of, any Grantor or any other Person that is a party to any Transaction Document or any other credit facility from the Administrative Agent to any Loan Party in respect of the Obligations or the Secured Obligations.

Section 3.7 Limitation by Law. All rights, remedies, and powers provided in this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Agreement invalid, unenforceable, in whole or in part, or not entitled to be recorded, registered, or filed under the provisions of any applicable law. Notwithstanding the general nature of the foregoing, to the extent the terms of any license, permit or other written agreement constituting or evidencing Collateral prohibits the transfer of such item of Collateral or rights thereunder, each Grantor only grants a security interest therein to the extent permitted by applicable law.

Section 3.8 Termination of this Agreement. Subject to Section 3.1, this Agreement shall terminate following termination of the Credit Agreement and the payment in full of all Obligations (other than indemnification obligations as to which no claim has been asserted).

Section 3.9 Relation to Other Security Documents. The provisions of this Agreement supplement the provisions of any and all other Security Documents granted to the Administrative Agent which secure the payment or performance of any of the Obligations. Nothing contained in any such Security Document shall derogate from any of the rights or remedies of the Administrative Agent under the Credit Agreement, this Agreement or any other Security Document.

Section 3.10 Successors and Assigns. This Agreement and all obligations of each Grantor hereunder shall be binding upon the successors and permitted assigns of each Grantor (including any debtor-in-possession on behalf of any Grantor) and shall inure to the benefit of the Administrative Agent and the other Secured Parties, all future holders of any instrument evidencing any of the Secured Obligations, and their respective successors and assigns. No assignments, transfers, or other dispositions of any agreement governing or instrument evidencing the Secured Obligations or any portion thereof or interest therein shall in any manner affect the Lien granted to the Administrative Agent. No Grantor may assign, sell, hypothecate, or otherwise transfer any interest in or obligation under this Agreement.

Section 3.11 Counterparts. 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. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or by electronic photocopy (i.e., “pdf”) shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 3.12 Governing Law. This Agreement and any claims, controversy, dispute or cause of action (whether in contract or tort or otherwise) based upon, arising out of or relating to this Agreement and the transactions contemplated hereby and thereby shall be governed by, and construed in accordance with, the law of the State of New York.

Section 3.13 Jurisdiction. Each Grantor irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Administrative Agent or any Secured Party, in any forum other than the courts of the State of New York sitting in New York County, and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto hereby irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by applicable law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action, litigation 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 or any Secured Party may otherwise have to bring any action or proceeding relating to this Agreement against the Grantors or their properties in the courts of any other jurisdiction to realize on the collateral or any other security for the Obligations or the Secured Obligations, or to enforce a judgment or other court order in favor of the Administrative Agent.

Section 3.14 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 ANY OTHER TRANSACTION DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON 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 3.15 Other Currencies. If for the purpose of obtaining or enforcing judgment or realizing upon the Collateral in any court it is necessary to convert any amount received or payable in a currency (“Second Currency”) other than the currency in which the Obligations are payable (“Primary Currency”) into Primary Currency, the rate of exchange that shall be applied shall be that at which in accordance with the Administrative Agent’s normal banking procedures the Administrative Agent could purchase Primary Currency with the Second Currency on the Business Day preceding the day on which final judgment is given. If payment of any amount of the Obligations is made to or received by the Administrative Agent in a Second Currency, whether by judicial judgment (and notwithstanding the rate of exchange actually applied in giving such judgment), from the proceeds of the sale or other disposition of Collateral or otherwise, the Obligations shall be discharged only the to the extent of the net amount of Primary Currency that the Administrative Agent is able in accordance with its normal banking procedures lawfully to purchase with such amount of Second Currency. To the extent that the Administrative Agent is not able to purchase with such amount of Second Currency sufficient Primary Currency to discharge the Primary Currency amount of the Obligations, the Obligations shall not be discharged with respect to such difference, and any such undischarged amount will be due as a separate debt and shall not be affected by payment of, or judgment being obtained for, any other sums under or in respect of this Agreement or the Obligations. To the extent that the Administrative Agent is able to purchase Primary Currency in an amount in excess of the amount necessary to discharge the Primary Currency amount of the Obligations, the Administrative Agent shall promptly remit such excess to the applicable Grantor or as a court of competent jurisdiction may direct.

Section 3.16 Waivers with Respect to Obligations. Each Grantor hereby waives any and all notice of or proof of reliance by the Administrative Agent on this Agreement, and the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Agreement, and all dealings between the Administrative Agent and such Grantor shall likewise be conclusively presumed to have been had or consummated in reliance on this Agreement.

Section 3.17 Section Titles. The Section titles contained in this Agreement are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

Section 3.18 No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

Section 3.19 Fraudulent Transfer Limitation. Anything contained in this Agreement to the contrary notwithstanding, the Secured Obligations of each Grantor hereunder shall be limited to a maximum aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11 of the United States Code or any applicable provisions of comparable state law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of such Grantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Grantor in respect of intercompany indebtedness to the Borrower or other Affiliates of the Borrower to the extent that such indebtedness would be discharged in an amount equal to the amount paid by such Grantor hereunder) and after giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation or contribution of such Grantor pursuant to (i) applicable law or (ii) any agreement providing for an equitable allocation among such Grantor and other Affiliates of the Borrower of obligations and arising under guaranties by such parties.

NOW, THEREFORE, for and in consideration of the sum of Ten U.S. Dollars ($10.00), the Lender Parties’ consent to the assumption by Newco of liability for the Assumed Amount pursuant to this Agreement, the mutual covenants and agreements of the parties in this Agreement, and other good and valuable considerations, the receipt and sufficiency of which are hereby acknowledged by the parties, the parties hereto agree as follows:

1. Incorporation of Preliminary Statements. The foregoing preliminary statements are true and correct and are hereby incorporated by reference for all purposes as if fully set forth herein. Terms not defined in this Agreement shall have the meanings ascribed to them in the Credit Agreement.

2. Definitions.

In consenting to the assumption of liability for the Debt by Newco, the Lender Parties are relying upon the representations, warranties and agreements set forth in the Credit Agreement. In addition, Lufkin and Newco hereby jointly and severally represent and warrant to the Lender Parties as follows:

(a) Newco has full and lawful authority and power to execute, acknowledge, deliver, and perform this Agreement and to assume the Assumed Debt. This Agreement has been duly executed and delivered by Newco and Lufkin and constitutes the legal, valid, and binding obligations of Newco and Lufkin, enforceable against Newco and Lufkin in accordance with their respective terms, except as limited by bankruptcy, insolvency, moratorium, reorganization, or similar laws of general application affecting creditors’ rights generally.

(d) Newco is now Solvent, and no bankruptcy or insolvency proceedings are pending or contemplated by or – to the best of Newco’s knowledge – against Newco. Newco’s assumption of the Debt pursuant to this Agreement do not and will not render Newco not Sol¬vent, cause Newco’s liabilities to exceed Newco’s assets, or leave Newco with too little capital to properly conduct all of its business as now conducted or contemplated to be conducted.

10. Further Assurances.

12. Merger. Neither any of the Lender Parties nor any of their respective employees, attorneys, representatives, or other agents has made any representation, covenant, promise, or warranty with respect to the subject matter hereof, express or implied, except as explicitly set forth herein, and no rights or privileges are or shall be acquired by Newco or Lufkin, by implication or otherwise, except as expressly set forth herein.

13. Severability. Should any term or provision of this Agreement or the application thereof to any person or circumstances shall, to any extent, be deemed invalid or unenforceable, the remainder of this Agreement or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable shall not be affected thereby and this Agreement shall be valid and enforced to the fullest extent permitted by applicable law.

This is an absolute guaranty of payment and not of collection, and an absolute guaranty of performance of all of the obligations of Lufkin Finance under the Loan Documents, and Guarantor WAIVES any right to require that any action be brought against Lufkin Finance or any other Person, or that the Administrative Agent, the Issuing Bank or any Lender be required to enforce, attempt to enforce or exhaust any rights, benefits or privileges of the Administrative Agent, the Issuing Bank or any Lender under any of the Loan Documents, by law or otherwise; provided that nothing herein shall be construed to prevent the Administrative Agent, the Issuing Bank or any Lender from exercising and enforcing at any time any right, benefit or privilege which the Administrative Agent, the Issuing Bank or such Lender may have under any Loan Document or by law from time to time, and at any time. Guarantor agrees that Guarantor's obligations hereunder are – and shall be – absolute, independent, and unconditional under any and all circumstances. Should the Administrative Agent, the Issuing Bank or any Lender seek to enforce Guarantor's obligations by action in any court, Guarantor WAIVES any requirement, substantive or procedural, that (a) the Administrative Agent, the Issuing Bank or any Lender pursue any foreclosure action, realize or attempt to realize on any security or preserve or enforce any deficiency claim against Lufkin Finance, Guarantor or any other Person after any such realization, (b) a judgment first be sought or rendered against Lufkin Finance, Guarantor or any other Person, (c) Lufkin Finance, Guarantor or any other Person be joined in such action, or (d) a separate action be brought against Lufkin Finance, Guarantor or any other Person. Guarantor's obligations under this Guaranty are several from those of Lufkin Finance or any other Person and are primary obligations concerning which Guarantor is the principal obligor. All waivers in this Guaranty or any of the other Loan Documents shall be without prejudice to the right of the Administrative Agent, the Issuing Bank or any Lender at its option to proceed against Lufkin Finance, Guarantor or any other Person, whether by separate action or by joinder. Guarantor agrees that its obligations under this Guaranty shall not be discharged except by payment of the Obligations in full, complete performance of all obligations of Lufkin Finance under the Loan Documents and termination of the Lenders’ obligations if any -- to make any further advances under the Loan Documents or extend other financial accommodations to Lufkin Finance.

3.8 Obligations Joint and Several with Other Guaranties. If any other Person makes any guaranty of any of the Obligations or gives any security for them, Guarantor's obligations under this Guaranty shall be joint and several with the obligations of such other Person pursuant to such agreement or other papers making the guaranty or giving the security.

3.9 Reinstatement. Guarantor agrees that, if at any time all or any part of any payment previously applied by the Administrative Agent, the Issuing Bank or any Lender to the Obligations is or must be returned by the Administrative Agent, the Issuing Bank or such Lender – or recovered from the Administrative Agent or such Lender – for any reason (including the order of any bankruptcy court), this Guaranty shall automatically be reinstated to the same effect as if the prior application had not been made, and, in addition, Guarantor hereby agrees to indemnify the Administrative Agent, the Issuing Bank and each Lender against, and to save and hold the Administrative Agent, the Issuing Bank and each Lender harmless from, any required return by the Administrative Agent, the Issuing Bank or any Lender – or recovery from the Administrative Agent or any Lender – of any such payment because of its being deemed preferential under applicable bankruptcy, receivership or insolvency laws, or for any other reason. The provisions of this Section 3.9 shall survive the termination of this Guaranty and any satisfaction and discharge of Lufkin Finance by virtue of any payment, court order or other law.

3.10 Effect of Stay. If an event permitting the acceleration of any of the Obligations shall at any time have occurred and be continuing and such acceleration shall at such time be prevented by reason of the pendency against Lufkin Finance of a case or proceeding under any bankruptcy or insolvency law, Guarantor agrees that, for purposes of this Guaranty and its obligations hereunder, the Obligations shall be deemed to have been accelerated and Guarantor shall forthwith pay such Obligations (including interest which but for the filing of such petition in bankruptcy would accrue on such Obligations), and the other obligations hereunder, without any further notice or demand. Guarantor agrees that, as between Guarantor and the Lenders, the Issuing Bank and the Administrative Agent, the Debt may be declared to be due and payable for the purposes of this Guaranty notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards Lufkin Finance and that in the event of a declaration or attempted declaration, the Debt shall immediately become due and payable by Guarantor for the purposes of this Guaranty.

3.11 Subrogation and Contribution. Guarantor expressly agrees that it will not be entitled to enforce any and all rights of subrogation, reimbursement, contribution, exoneration and indemnity, contractual, statutory or otherwise, against the Administrative Agent, the Issuing Bank and the Lenders individually and collectively, including any claim or right of subrogation under the Bankruptcy Code (Title 11 of the U.S. Code) or any successor or similar Law arising from the existence or performance of this Guaranty, until the termination of this Guaranty, and until such termination Guarantor irrevocably agrees that it will not be entitled to enforce any right to enforce any remedy which the Administrative Agent, the Issuing Bank or any Lender now has or may hereafter have against Lufkin Finance and the benefit of and any right to participate in any security now or hereafter held by the Administrative Agent, the Issuing Bank or any Lender. Until such termination, if any amount shall be paid by or on behalf of Lufkin Finance or any other Person to Guarantor on account of any of the rights waived in this Section 3.11, such amount shall be held by Guarantor in trust, segregated from other funds of Guarantor, and shall, forthwith upon receipt by Guarantor, be turned over to the Administrative Agent for the account of the Issuing Bank and each Lender in the exact form received by Guarantor (duly indorsed by Guarantor to the Administrative Agent, the Issuing Bank or such Lender, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine. The provisions of this Section 3.11 shall survive the term of this Guaranty, the payment in full of the Obligations and the termination of the Commitments.

3.12 Administrative Matters. If, in the exercise of any of its rights and remedies, the Administrative Agent, the Issuing Bank or any Lender shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against Lufkin Finance or Guarantor, for any reason, Guarantor hereby consents to such action, even if such action by the Administrative Agent, the Issuing Bank or such Lender shall result in a full or partial loss of any rights of subrogation which Guarantor might otherwise have had but for such action by the Administrative Agent, the Issuing Bank or such Lender. Any election of remedies which results in the denial or impairment of the right of the Administrative Agent, the Issuing Bank or any Lender to seek a deficiency judgment against Lufkin Finance shall not impair Guarantor's obligation to pay the full amount of Guarantor's Debt.

ARTICLE IV

4.1 Relationship to the Lufkin Finance. Lufkin Finance is an indirect Wholly-Owned Subsidiary of Guarantor. The Debt is being assumed by Lufkin Finance as an integral part of an arrangement by which another Subsidiary of Guarantor shall acquire substantially all of the assets of ▇▇▇▇▇’▇ Oilfield Supply, Ltd., an Alberta corporation. Guarantor has determined that its liability and obligation under this Guaranty may reasonably be expected to substantially benefit it directly or indirectly, and its board of directors (or such board's duly authorized and appointed designee) or other equivalent body has made that determination. The transactions contemplated in this Guaranty produce distinct and identifiable financial and economic direct or indirect benefits to Guarantor. Guarantor has had full and complete access to the underlying papers relating to the Obligations and all other papers executed by Lufkin Finance or any other Person in connection with the Obligations, has reviewed them and is fully aware of the meaning and effect of their contents. Guarantor is fully informed of all circumstances which bear upon the risks of executing this Guaranty and which a diligent inquiry would reveal. Guarantor has adequate means to obtain from the Lufkin Finance on a continuing basis information concerning Lufkin Finance’s financial condition, and is not depending on the Administrative Agent, the Issuing Bank or any Lender to provide such information, now or in the future. Guarantor agrees that neither the Administrative Agent, the Issuing Bank nor any Lender shall have any obligation to advise or notify it or to provide it with any data or information.

4.2 Guarantor Solvent. Guarantor is now Solvent, and no bankruptcy or insolvency proceedings are pending or contemplated by or – to the best of Guarantor's knowledge – against Guarantor. Guarantor's liabilities and obligations under this Guaranty do not and will not render Guarantor not Solvent, cause Guarantor's liabilities to exceed Guarantor's assets or leave Guarantor with too little capital to properly conduct all of its business as now conducted or contemplated to be conducted.

ARTICLE V

5.1 Term. Subject to the automatic reinstatement provisions of Article III, this Guaranty shall terminate and be of no further force or effect upon the occurrence of all of the following: (i) the full payment of the Debt, (ii) the final expiry of all Letters of Credit, (iii) the complete performance of all of the obligations of Lufkin Finance under the Loan Documents, and (iv) the final termination of the obligations, if any, of the Administrative Agent and the Lenders to make any further Loans or to issue, amend, renew or extend Letters of Credit under the Credit Agreement and the other Loan Documents or to provide any other financial accommodations to Lufkin Finance.

ARTICLE VI

6.2 Subordination. Guarantor hereby expressly covenants and agrees for the benefit of the Administrative Agent, the Issuing Bank and each Lender that all obligations and liabilities of Lufkin Finance and its Subsidiaries to Guarantor of whatsoever description (including all intercompany receivables of Guarantor from Lufkin Finance or any of its Subsidiaries) shall be subordinated and junior in right of payment to the Obligations. Guarantor shall not accept any payment on any indebtedness of Lufkin Finance or any of its Subsidiaries until the termination of this Guaranty, shall in no circumstance whatsoever attempt to set-off or reduce any obligations because of such indebtedness and shall, if the Administrative Agent shall so request, collect and receive such indebtedness as trustee for the Administrative Agent, the Issuing Bank and the Lenders and pay over all sums so collected to the Administrative Agent for the account of the Issuing Bank and the Lenders on account of the Obligations but without reducing or affecting in any manner the liability of Guarantor under this Guaranty.

6.3 Waiver of Suretyship Rights. By signing this Guaranty, Guarantor WAIVES each and every right to which it may be entitled by virtue of any suretyship law now or hereafter in existence.

6.7 Governing Law and Jurisdiction.

(c) Guarantor 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 action or proceeding arising out of or relating to this Guaranty in any court referred to in paragraph (b) of this Section. Guarantor 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.

6.9 Survival. The representations, covenants and agreements set forth in this Guaranty shall continue and survive until the final termination of this Guaranty in accordance with Article V.

6.12 Setoff. Guarantor agrees that, in addition to (and without limitation of) any rights of setoff, banker's lien or counterclaim any Lender or the Issuing Bank may otherwise have, each Lender and the Issuing Bank shall be entitled, at its option, to offset balances (general or special, time or demand, provisional or final) held by it for the account of Guarantor at any of such Lender's or the Issuing Bank's offices, in dollars or in any other currency, against any amount payable by Guarantor under this Guaranty which is not paid when due (regardless of whether such balances are then due to Guarantor), in which case it shall promptly notify Guarantor thereof; provided that failure to give such notice shall not affect the validity of such offset.

6.13 Captions. The headings and captions in this Guaranty are for convenience only and shall not affect the interpretation or construction of this Guaranty.

THIS GUARANTY AGREEMENT is executed as of the date first above written.
