The Borrower may, by notice to the Administrative Agent (who shall promptly notify the Lenders) not later than 30 days prior to the Maturity Date then in effect hereunder (the “Existing Maturity Date”), make a one-time request that each Lender extend such Lender’s Maturity Date for an additional 364 days from the Existing Maturity Date. The date on which the Administrative Agent provides to the Lenders the notice referenced above is hereinafter referred to as the “Notice Date.”

(ii) Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not later than 15 days after the Notice Date, advise the Administrative Agent whether or not such Lender agrees to such extension and any Lender that does not so advise the Administrative Agent on or before the date that is 15 days after the Notice Date shall be deemed to be a Non-Extending Lender. Each Lender that determines not to so extend its Maturity Date shall be referred to herein as a “Non-Extending Lender”. Each Lender that determines to extend its Maturity Date shall be referred to herein as an “Extending Lender”. The election of any Lender to agree to such extension shall not obligate any other Lender to so agree.

(iii) Additional Commitment Lenders. The Borrower shall have the right on or before the Existing Maturity Date to replace each Non-Extending Lender with, and add as “Lenders” under this Agreement in place thereof, one or more Eligible Assignees (each, an “Additional Commitment Lender”), each of which Additional Commitment Lenders shall have entered into an Assignment and Assumption pursuant to which such Additional Commitment Lender shall, effective as of the Existing Maturity Date, undertake a Revolving Commitment (and, if any such Additional Commitment Lender is already a Lender, its Revolving Commitment shall be in addition to such Lender’s Revolving Commitment hereunder on such date).

(iv) Minimum Extension Requirement. If (and only if) the total of the Revolving Commitments of the Lenders that have agreed so to extend their Maturity Date and the additional Revolving Commitments of the Additional Commitment Lenders shall be more than 50% of the aggregate amount of the Revolving Commitments in effect immediately prior to the Existing Maturity Date, then, effective as of the Existing Maturity Date, the Maturity Date of each Extending Lender and of each Additional Commitment Lender shall be extended to the date falling 364 days after the Existing Maturity Date and each Additional Commitment Lender shall thereupon become a “Lender” for all purposes of this Agreement.

(v) Conditions to Effectiveness of Extensions. Notwithstanding the foregoing, the extension of the Maturity Date pursuant to this Section shall not be effective with respect to any Lender unless: (A) no Default or Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto; (B) the representations and warranties contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); (C) the receipt by the Administrative Agent of such evidence of appropriate authorization on the part of the Borrower with respect to such extension as the Administrative Agent may reasonably request; (D) on the Maturity Date (without giving effect to any extension) of each Non-Extending Lender, the Borrower shall repay any Revolving Advances outstanding on such date (and pay any additional amounts required pursuant to Section 2.11) and any other Obligations owing to such Non-Extending Lender to each

such Non-Extending Lender and the Revolving Commitments of the Non-Extending Lenders shall be terminated; and (E) the Borrower shall prepay any Revolving Advances outstanding on such date (and pay any additional amounts required pursuant to Section 2.11) to the extent necessary to keep outstanding Revolving Advances ratable with any revised Applicable Percentages of the respective Lenders effective as of such date.

(vi) Conflicting Provisions. This Section shall supersede any provisions in Section 2.13(f) or 9.2 to the contrary.

Section 2.2 Evidence of Indebtedness. The Advances made by each Lender, including the Swingline Lender, shall be evidenced by one or more accounts or records maintained by such Lender or the Swingline Lender and by the Administrative Agent. The accounts or records maintained by the Administrative Agent, the Lenders and the Swingline Lender shall be conclusive absent manifest error of the amount of the Advances made by such Lenders or the Swingline Lender to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender or the Swingline Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender to the Borrower made through the Administrative Agent, the Borrower shall execute and deliver to such Lender or the Swingline Lender (through the Administrative Agent) a Note which shall evidence such Lender’s Revolving Advances or Swingline Advances to the Borrower in addition to such accounts or records. Each Lender may attach schedules to such Note and endorse thereon the date, Type (if applicable), amount, currency and maturity of its Revolving Advances or Swingline Advances and payments with respect thereto.

Section 2.3 Letters of Credit.

(a) Commitment for Letters of Credit. Subject to the terms and conditions set forth in this Agreement and in reliance upon the agreements of the other Lenders set forth in this Section, the Issuing Lender agrees to, from time to time on any Business Day during the period from the Closing Date until the Maturity Date, issue, increase or extend the expiration date of, the Letters of Credit for the account of the Parent or any Subsidiary thereof.

(b) Limitations. Notwithstanding the foregoing, no Letter of Credit will be issued, increased, or extended:

(i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) the Letter of Credit Maximum Amount and (B) an amount equal to (1) the aggregate Revolving Commitments in effect at such time minus (2) the Outstandings.

(ii) if such Letter of Credit supports the repayment of indebtedness for borrowed money of any Person;

(iii) unless such Letter of Credit is in form and substance acceptable to the applicable Issuing Lender in its sole discretion;

(iv) unless the Borrower has delivered to the applicable Issuing Lender a completed and executed Letter of Credit Application; provided that, if the terms of any Letter of Credit Application conflicts with the terms of this Agreement, the terms of this Agreement shall control;

(v) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or (B) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender; and

(vi) if any Lender is at such time a Defaulting Lender hereunder, unless the Issuing Lender has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Lender’s risk with respect to such Lender.

(c) Requesting Letters of Credit. Each Letter of Credit Extension shall be made pursuant to a Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, given by the Borrower to the Administrative Agent for the benefit of the applicable Issuing Lender by telecopy or in writing not later than 11:00 a.m. (Houston, Texas, time) on the third Business Day before the proposed date of the Letter of Credit Extension. Each Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, shall be fully completed and shall specify the information required therein. Each Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, shall be irrevocable and binding on the Borrower. Subject to the terms and conditions hereof, the applicable Issuing Lender shall on the date of such Letter of Credit Extension, make such Letter of Credit Extension to the beneficiary of such Letter of Credit.

(d) Reimbursements for Letters of Credit; Funding of Participations. Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit with the accompanying documentation required thereby, the applicable Issuing Lender shall notify the Administrative Agent thereof. No later than 11:00 a.m. on the date of any payment to be made by such Issuing Lender under a Letter of Credit, the Borrower agrees to pay to such Issuing Lender an amount equal to any amount paid by such Issuing Lender under or in respect of such Letter of Credit. In the event an Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not promptly reimbursed by the Borrower as required herein, such Issuing Lender shall give notice of such payment to the Administrative Agent. In such event, the Borrower shall be deemed to have requested a Base Rate Advance (notwithstanding any minimum size or increment limitations on individual Advances). Each Lender (including the Lender acting as Issuing Lender) shall, upon notice from the Administrative Agent that the Borrower has requested or is deemed to have requested an Advance pursuant to Section 2.5 and regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.5, or (C) a Default exists, make funds available to the Administrative Agent for the account of the applicable Issuing Lender in an amount equal to such Lender’s Applicable Percentage of the amount of such Advance not later than 1:00 p.m. (Houston, Texas, time) on the Business Day specified in such notice by the Administrative Agent, whereupon (i) each Lender that so makes funds available shall be deemed to have made a Base Rate Advance under to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the applicable Issuing Lender. If any such Lender shall not have so made such Advance available to the Administrative Agent pursuant to this Section 2.3, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Overnight Rate for such day for the first three days and thereafter the interest rate applicable to such Base Rate Advances and (B) the Maximum Rate. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat each payment under a Letter of Credit not immediately reimbursed by the Borrower as a Revolving Borrowing comprised of Base Rate Advances to the Borrower. If for any reason any payment pursuant to a request for draw presented under a Letter of Credit is not refinanced by a Revolving Borrowing in accordance with this Section 2.3(d), the Issuing Lender shall be deemed to have requested that each of the applicable Lenders fund its risk participation in the relevant Letter of Credit Obligations and each such Lender’s payment to the

Administrative Agent for the account of the Issuing Lender pursuant to this Section 2.3(d) shall be deemed payment in respect of such participation.

(e) Participations. Upon the date of the issuance or increase of a Letter of Credit, the applicable Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from the Issuing Lender a participation in the related Letter of Credit Obligations equal to such Lender’s Applicable Percentage at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The applicable Issuing Lender shall promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued or increased and the actual dollar amount of such Lender’s participation in such Letter of Credit. Each Lender’s obligation to purchase participating interests pursuant to this Section and to reimburse such Issuing Lender for such Lender’s Applicable Percentage of any payment under a Letter of Credit by such Issuing Lender not reimbursed in full by the Borrower shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any of the circumstances described in paragraph (f) below, (ii) the occurrence and continuance of a Default, (iii) an adverse change in the financial condition of the Borrower or (iv) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing, except for any such circumstance, happening or event constituting or arising from gross negligence or willful misconduct on the part of the applicable Issuing Lender.

(f) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

(i) any lack of validity or enforceability of any Letter of Credit Documents;

(ii) any amendment or waiver of or any consent to departure from any Letter of Credit Document to which the Borrower has consented;

(iii) the existence of any claim, set-off, defense or other right which any Credit Party may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any Issuing Lender, any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

(iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent any Issuing Lender would not be liable therefor pursuant to the following paragraph (h);

(v) payment by the Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (f) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit, including those specified in Section 2.3(h).

(g) Cash Collateralization. With respect to (i) each Letter of Credit which has an expiration date beyond the Maturity Date, on or prior to the 30th day prior to the Maturity Date or (ii) all outstanding

Letters of Credit, if the Revolving Commitments are terminated in whole pursuant to Section 2.1(b) or Article VII, on the date of such termination, the Borrower shall deposit into the Cash Collateral Account in accordance with paragraph (i) below cash in an amount equal to 105% of the Letter of Credit Exposure of such Letters of Credit or otherwise make arrangements satisfactory to the Administrative Agent to secure the release of such Letters of Credit. If the Borrower has deposited 105% of the Letter of Credit Exposure into the Cash Collateral Account as of the Maturity Date and no other Default or Event of Default has occurred and is continuing, each Lender’s obligation to purchase participating interests pursuant to this Section and to reimburse such Issuing Lender for such Lender’s Applicable Percentage of any payment under a Letter of Credit by such Issuing Lender not reimbursed in full by the Borrower shall be terminated as of the Maturity Date.

(h) Liability of Issuing Lenders. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its or any Credit Party’s use of such Letter of Credit. Neither Issuing Lender nor any of their respective officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; or

(iii) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING AN ISSUING LENDER’S OWN NEGLIGENCE),

except that the Borrower shall have a claim against the applicable Issuing Lender, and the applicable Issuing Lender shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) such Issuing Lender’s willful misconduct or gross negligence (as determined in a final, non-appealable judgment of a court of competent jurisdiction) in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) such Issuing Lender’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit, in either case notwithstanding the unconditional and irrevocable nature of the Borrower’s obligations under this Agreement as set forth in Section 2.3(f). In furtherance and not in limitation of the foregoing, the Issuing Lenders may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(i) Cash Collateral Account.

(i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to the terms hereof, then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Administrative Agent’s standard form assignment of deposit accounts, that the Administrative Agent requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent a first priority security interest in such account and the funds therein and giving the Administrative Agent “control” over the Cash Collateral Account as such term is defined in the applicable Uniform Commercial Code. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in the Cash Collateral Account, whenever established, all funds held in the Cash Collateral Account from time to time, and all proceeds thereof as security for

the payment of the obligation. Except as provided in Section 2.3(i)(ii) blow, the Borrower shall have no access and no rights of withdrawal from the case collateral Account.

(ii) Funds held in the Cash Collateral Accounts shall be held as cash collateral for obligations with respect to Letters of Credit. Such funds shall be promptly applied by the Administrative Agent at the request of the applicable Issuing Lender to any reimbursement or other obligations under the applicable Letters of Credit that exist or occur. To the extent that any surplus funds are held in the Cash Collateral Account above the Letter of Credit Exposure during the existence of an Event of Default the Administrative Agent may (A) hold such surplus funds in the Cash Collateral Account as cash collateral for the Obligations or (B) apply such surplus funds to any Obligations in any manner directed by the Majority Lenders. If no Default exists, the Administrative Agent shall release to the Borrower at the Borrower’s written request any funds held in the Cash Collateral Account in excess of 105% of the then existing Letter of Credit Exposure. The Administrative Agent shall invest the funds in the Cash Collateral Account in an interest-bearing account or other investment approved by the Borrower. The Administrative Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property or in accordance with the Borrower’s instructions or as otherwise approved by the Borrower, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

(j) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of the Borrower, the Borrower shall be obligated to reimburse the applicable Issuing Lender hereunder for any and all drawings under such Letter of Credit issued (or deemed issued) hereunder. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of its Subsidiaries or any Subsidiary of the Parent inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

(k) Defaulting Lender. At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or any Issuing Lender (with a copy to the Administrative Agent) the Borrower shall Cash Collateralize each Issuing Lender’s Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 2.16(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount.

(i) Grant of Security Interest. The Borrower, and to the extent Cash Collateral is provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the Issuing Lenders, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of Letter of Credit Obligations, to be applied pursuant to clause (ii) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent and the Issuing Lender as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.1(k) or Section 2.16 in respect of Letters of Credit shall

be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Letter of Credit Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce an Issuing Lender’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.1(k) and shall, upon written request of the Person providing such Cash Collateral, be refunded following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent and each Issuing Lender that there exists excess Cash Collateral; provided that, subject to Section 2.16, the Person providing Cash Collateral and the Issuing Lender may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

Section 2.4 Swingline Advances.

(a) Commitment. On the terms and conditions set forth in this Agreement, subject to Section 2.16(d), the Swingline Lender agrees to, from time-to-time on any Business Day from the Closing Date until the last Business Day occurring before the Maturity Date, make Swingline Advances to the Borrower in an aggregate principal amount not to exceed the Swingline Commitment at any time, provided that (i) after giving effect to such Swingline Advance, the Outstandings shall not exceed the aggregate Revolving Commitments in effect at such time, (ii) no Swingline Advance may mature after the Maturity Date, and (iii) no Swingline Advance shall be made by the Swingline Lender if the conditions set forth in Section 3.2 have not been met as of the date of such Swingline Advance. The Borrower agrees that the giving of the applicable Notice of Borrowing and the acceptance by the Borrower of the proceeds of such Swingline Advance shall constitute a representation and warranty by the Borrower that on the date of such Swingline Advance the conditions set forth in Section 3.2 have been met. Immediately upon the making of a Swingline Advance, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Advance in an amount equal to its Applicable Percentage of such Swingline Advance.

(b) Evidence of Indebtedness. The indebtedness of the Borrower to the Swingline Lender resulting from Swingline Advances shall be evidenced as set forth in Section 2.2.

(c) Prepayment. Within the limits expressed in this Agreement, amounts advanced pursuant to Section 2.4(a) may from time to time be borrowed, prepaid without penalty, and reborrowed. If the amount of aggregate outstanding amount of Swingline Advances ever exceeds the Swingline Commitment, the Borrower shall, upon receipt of written notice of such condition from the Swingline Lender and to the extent of such excess, prepay to the Swingline Lender outstanding principal of the Swingline Commitment such that such excess is eliminated.

(d) Refinancing of Swingline Advances.

(i) The Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to so request on its behalf), that each Lender make a Base Rate Advance in an amount equal to such Lender’s Applicable Percentage of the amount of Swingline Advances then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Notice of Borrowing for purposes hereof), without regard to the minimum and multiples specified in Section 2.5(c) for the principal amount of Revolving Borrowings but subject to the unutilized portion of the Revolving Commitments and the

conditions set forth in Section 3.2. The Swingline Lender shall furnish the Borrower with a copy of the applicable Notice of Borrowing promptly after delivering such notice to the Administrative Agent. Regardless of whether the request for such Base Rate Advance complies with Section 2.5, each Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Notice of Borrowing available to the Administrative Agent in Same Day Funds for the account of the Swingline Lender at the Administrative Agent’s Lending Office not later than 1:00 p.m. on the day specified in such Notice of Borrowing, whereupon, subject to Section 2.4(d)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Advance to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swingline Lender.

(ii) If for any reason any Swingline Advance cannot be refinanced by such a Revolving Borrowing in accordance with Section 2.4(d)(i), the applicable Notice of Borrowing submitted by the Swingline Lender as set forth herein shall be deemed to be a request by the Swingline Lender that each of the applicable Lenders fund its risk participation in the relevant Swingline Advances and each such Lender’s payment to the Administrative Agent for the account of the Swingline Lender pursuant to Section 2.4(d)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Administrative Agent for the account of the Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.4(d) by the time specified in Section 2.4(d)(i), the Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect. A certificate of the Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Advances or to purchase and fund risk participations in Swingline Advances pursuant to this Section 2.4(d) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against any Swingline Lender, the Borrower, or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Advances pursuant to Section 2.4(d)(i) is subject to the conditions set forth in Section 3.2. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay the Swingline Advances, together with interest as provided herein.

(e) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swingline Advance, if the Swingline Lender receives any payment on account of such Swingline Advance, the Swingline Lender will distribute to such Lender its Applicable Percentage of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by the Swingline Lender.

(ii) If any payment received by the Swingline Lender in respect of principal or interest on any Swingline Advance is required to be returned by the Swingline Lender under any of the circumstances described in Section 9.12 (including pursuant to any settlement entered into by the Swingline Lender in its discretion), each Lender shall pay to the Swingline Lender its Applicable

Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the applicable Overnight Rate. The Administrative Agent will make such demand upon the request of the Swingline Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(f) Interest for Account of Swingline Lender. The Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Advances. Until each Lender funds its Advances or risk participation pursuant to this Section to refinance such Lender’s Applicable Percentage of the applicable Swingline Advances, interest in respect of such Applicable Percentage shall be solely for the account of the Swingline Lender.

(g) Payments Directly to Swingline Lender. The Borrower shall make all payments of principal and interest in respect of the Swingline Advances directly to the Swingline Lender.

(h) Method of Borrowing. Except as provided in the clause (c) above, each request for a Swingline Advance shall be made pursuant to telephone notice to the Swingline Lender given no later than 11:00 a.m. (Houston, Texas time) on the date of the proposed Swingline Advance, promptly confirmed by a completed and executed Notice of Borrowing facsimiled to the Administrative Agent and the Swingline Lender. The Swingline Lender will promptly make such Swingline Advance available to the Borrower at the Borrower’s account with the Administrative Agent.

Section 2.5 Borrowings; Procedures and Limitations.

(a) Notice of Borrowings. Each Revolving Borrowing shall be made pursuant to a Notice of Borrowing and given by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) on the third Business Day before the date of the proposed Revolving Borrowing in the case of a Eurodollar Advance, and by the Borrower to the Administrative Agent not later than 12:00 p.m. (Houston, Texas time) one Business Day before the date of the proposed Revolving Borrowing in the case of a Base Rate Advance. The Administrative Agent shall give each applicable Lender prompt notice on the day of receipt of timely Notice of Borrowing of such proposed Revolving Borrowing by facsimile. Each Notice of Borrowing shall be by facsimile specifying the (i) requested date of such Revolving Borrowing (which shall be a Business Day), (ii) requested Type of Advances comprising such Revolving Borrowing, (iii) aggregate amount of such Revolving Borrowing, and (iv) if such Revolving Borrowing is to be comprised of Eurodollar Advances, the Interest Period for such Advances. In the case of a proposed Revolving Borrowing comprised of Eurodollar Advances, the Administrative Agent shall promptly notify each applicable Lender of the applicable interest rate under Section 2.9, as applicable. Each Lender shall before 11:00 a.m. (Houston, Texas time) on the date of the proposed Revolving Borrowing, make available for the account of its Lending Office to the Administrative Agent at its address referred to in Section 9.7, or such other location as the Administrative Agent may specify by notice to the Lenders, in Same Day Funds, such Lender’s Applicable Percentage of such Revolving Borrowing. Promptly upon the Administrative Agent’s receipt of such funds (but in any event not later than 3:00 p.m. (Houston, Texas time) on the date of the proposed Revolving Borrowing) and provided that the applicable conditions set forth in Article III have been satisfied, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent.

(b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office no later than 12:00 p.m. (Houston, Texas time) (i) at least one Business Day in advance of the proposed Conversion date in the case of a Conversion of such Advances to Base Rate Advances, and (ii) at least

three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurodollar Advances. Each such Notice of Conversion or Continuation shall be in writing or facsimile, specifying (A) the requested Conversion or continuation date (which shall be a Business Day), (B) the Revolving Borrowing amount and Type of the Advances to be Converted or continued, (C) whether a Conversion or continuation is requested, and if a Conversion, into what Type of Advances, and (D) in the case of a Conversion to, or a continuation of, Eurodollar Advances, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each applicable Lender with a copy thereof and, in the case of a Conversion to or a continuation of Eurodollar Advances, notify each applicable Lender of the applicable interest rate under Section 2.9 as applicable. For purposes other than the conditions set forth in Section 3.2, the portion of Advances comprising part of the same Revolving Borrowing that are Converted to Advances of another Type shall constitute a new Revolving Borrowing.

(i) Each Revolving Borrowing shall (A) be in an aggregate amount not less than $3,000,000 and in integral multiples of $1,000,000 in excess thereof in case of Eurodollar Advances and in an aggregate amount not less than $500,000 and in integral multiples of $100,000 in excess thereof in case of Base Rate Advances, (B) consist of Advances of the same Type made, Converted or continued on the same day by the Lenders according to their Applicable Percentage, and (C) denominated only in Dollars.

(ii) At no time shall there be more than eight Interest Periods applicable to outstanding Eurodollar Advances.

(iii) The Borrower may not select Eurodollar Advances for any Revolving Borrowing to be made, Converted or continued if a Default or Event of Default has occurred and is continuing.

(iv) If any Lender shall, at least one Business Day prior to the requested date of any Revolving Borrowing comprised of Eurodollar Advances, notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make Eurodollar Advances or to fund or maintain Eurodollar Advances, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars in the applicable interbank market, then (1) such Lender’s Applicable Percentage of the amount of such Revolving Borrowing shall be made as a Base Rate Advance of such Lender, (2) such Base Rate Advance shall be considered part of the same Revolving Borrowing and interest on such Base Rate Advance shall be due and payable at the same time that interest on the Eurodollar Advances comprising the remainder of such Revolving Borrowing shall be due and payable, and (3) any obligation of such Lender to make, continue, or Convert to, Eurodollar Advances, including in connection with such requested Revolving Borrowing, shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist.

(v) If the Administrative Agent is unable to determine the Eurodollar Rate for Eurodollar Advances comprising any requested Revolving Borrowing, the right of the Borrower to select Eurodollar Advances for such Revolving Borrowing or for any subsequent Revolving Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the applicable Lenders that the circumstances causing such suspension no longer exist, and each Revolving Advance comprising such Revolving Borrowing shall be made as a Base Rate Advance.

(vi) If the Majority Lenders shall, at least one Business Day before the date of any requested Revolving Borrowing, notify the Administrative Agent that (A) the Eurodollar Rate for Eurodollar Advances comprising such Revolving Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Advances, as the case may be, for such Revolving Borrowing, or (B) deposits are not being offered to banks in the applicable offshore interbank market for Dollars for the applicable amount and Interest Period of such Eurodollar Advance, then the Administrative Agent shall give notice thereof to the Borrower and the Lenders and the right of the Borrower to select Eurodollar Advances for such Revolving Borrowing or for any subsequent Revolving Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Revolving Borrowing shall be made as a Base Rate Advance.

(vii) If the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1 and paragraph (a) or (b) above, the Administrative Agent will forthwith so notify the Borrower and the applicable Lenders and such affected Advances will be made available to the Borrower on the date of such Revolving Borrowing as Base Rate Advances or, if such affected Advances are existing Advances, will be Converted into Base Rate Advances at the end of Interest Period then in effect.

(viii) Swingline Advances may not be Converted or continued.

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Borrower.

(e) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Revolving Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Revolving Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Revolving Borrowing.

(f) Funding by Lenders; Administrative Agent’ Reliance. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Revolving Borrowing of Eurodollar Advances, or prior to noon on the date of any Revolving Borrowing of Base Rate Advances, that such Lender will not make available to the Administrative Agent such Lender’s share of such Revolving Borrowing, the Administrative Agent may assume that such Lender has made such share available in accordance with and at the time required in Section 2.5 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Revolving Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the Overnight Rate and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to the requested Revolving Borrowing. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Revolving Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Advance included in such Revolving Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such

payment to the Administrative Agent. A notice of the Administrative Agent to any Lender or Borrower with respect to any amount owing under this subsection (f) shall be conclusive, absent manifest error.

Section 2.6 Prepayments. No Borrower shall have any right to prepay any principal amount of any Advance except as provided in this Section 2.6. Each payment of any Advance pursuant to this Section 2.6 shall be made in a manner such that all Advances comprising part of the same Revolving Borrowing are paid in whole or ratably in part other than Advances owing to a Defaulting Lender as provided in Section 2.16.

(a) Optional. The Borrower may elect to prepay any Revolving Borrowing, in whole or in part, without penalty or premium except as set forth in Section 2.11 and after giving by 11:00 a.m. (Houston, Texas time) (i) in the case of Eurodollar Advances, at least three Business Days’ or (ii) in case of Base Rate Advances, one Business Day’s prior written notice to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Revolving Borrowing in whole or ratably (giving effect to Section 2.16, if applicable) in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.11 as a result of such prepayment being made on such date; provided that (A) each optional partial prepayment of Eurodollar Advances shall be in a minimum amount not less than $3,000,000 and in multiple integrals of $1,000,000 in excess thereof and (B) each optional prepayment of Base Rate Advances shall be in a minimum amount not less than $500,000 and in multiple integrals of $100,000 in excess thereof.

(b) Mandatory. (i) On any date that Outstandings exceeds the aggregate amount of Revolving Commitments, the Borrower shall, within one Business Day, to the extent of such excess, first prepay to the Swingline Lender the outstanding principal amount of the Swingline Advances, second, prepay to the Lenders on a pro rata basis the outstanding principal amount of the Revolving Advances and third, make deposits into the Cash Collateral Account to provide cash collateral in the amount of such excess for the Letter of Credit Exposure. (ii) If a Commitment Increase is effected as permitted under Section 2.1(c), the Borrower shall prepay any Revolving Advances outstanding on such Increase Date to the extent necessary to keep the outstanding Revolving Advances ratable to reflect the revised Applicable Percentages arising from such Commitment Increase. Any prepayment made by Borrower in accordance with this clause (b)(ii) may be made with the proceeds of Revolving Advances made by all the Lenders in connection the Commitment Increase occurring simultaneously with the prepayment.

(c) Interest; Costs. Each prepayment pursuant to this Section 2.6 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.11 as a result of such prepayment being made on such date.

Section 2.8 Fees.

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a Commitment Fee on the average daily amount by which such Lender’s Revolving Commitment exceeds such Lender’s outstanding Revolving Advances plus such Lender’s Applicable Percentage of the Letter of Credit Exposure at the per annum rate equal to the Applicable Margin for Commitment Fees for such period; provided that no such commitment fee shall accrue on the Commitment of a Defaulting Lender during the period such Lender remains a Defaulting Lender. The Commitment Fee is due quarterly in arrears on March 31, June 30, September 30, and December 31 of each year commencing on June 30, 2012, and on the Maturity Date.

Section 2.10 Illegality. If any Lender shall notify the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make, maintain, or fund any Eurodollar Advances of such Lender then outstanding hereunder, (a) the Borrower shall, no later than 11:00 a.m. (Houston, Texas, time) (i) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Advance, or (ii) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the Eurodollar Advances of such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.11 as a result of such prepayment being made on such date, (b) such Lender shall simultaneously make a Base Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Advances prepaid to such Lender, and (c) the right of the Borrower to select Eurodollar Advances from such Lender for any subsequent Revolving Borrowing shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist.

Section 2.11 Breakage Costs.

(a) Funding Losses. In the case of any Revolving Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Advances, the Borrower hereby indemnifies each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Revolving Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (excluding any loss of anticipated profits), cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by such Lender to fund the Eurodollar Advance to be made by such Lender as part of such Revolving Borrowing when such Eurodollar Advance as a result of such failure, is not made on such date.

(b) Prepayment Losses. If (i) any payment of principal of any Eurodollar Advance is made other than on the last day of the Interest Period for such Advance (including any deemed payment or repayment and any reallocated repayment to Non-Defaulting Lenders provided for in Section 2.13(a) or Section 2.16) as a result of any prepayment, payment, the acceleration of the maturity of the Obligations, or for any other reason, (ii) the Borrower fails to make a principal or interest payment with respect to any Eurodollar Advance on the date such payment is due and payable, or (iii) any failure by the Borrower to make payment of any Advance or reimbursement of drawing under any Letter of Credit (or interest due thereon) on its scheduled due date; the Borrower shall, within 10 days of any written demand sent by the Administrative Agent on behalf of a Lender to the Borrower, pay to the Administrative Agent for the

Section 2.12 Increased Costs.

(a) Increased Costs Generally. 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 of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 2.12(e)) or any Issuing Lender;

(ii) subject 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 Issuing Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or 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 loan or of maintaining its obligation to make or accept and purchase any such loan, or to increase the cost to such Lender, such Issuing Lender 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, such Issuing Lender or such other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, such Issuing Lender or such other Recipient, the Borrower will pay to such Lender, such Issuing Lender or such other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, such Issuing Lender or such other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or Issuing Lender determines that any Change in Law affecting such Lender or Issuing Lender or any lending office of such Lender or such Lender’s or Issuing Lender’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 Lender’s capital or on the capital of such Lender’s or Issuing Lender’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 Advances held by, such Lender, or the Letters of Credit issued by such Issuing Lender, to a level below that which such Lender or Issuing Lender or such Lender’s or Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Lender’s policies and the policies of such Lender’s or Issuing Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or Issuing Lender, such additional amount or amounts as will compensate such Lender or such Issuing Lender or such Lender’s or Issuing Lender’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or Issuing Lender or its holding company, as

the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender or Issuing Lender, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Lender’s right to demand such compensation.

(e) Additional Reserve Requirement. The Borrower shall pay to each Lender Party, (i) as long as such Lender Party shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurodollar funds or deposits (currently known as Eurocurrency Liabilities), additional interest on the unpaid principal amount of each Eurodollar Advance equal to the actual costs of such reserves allocated to such Advance by such Lender Party (as determined by such Lender Party in good faith, which determination shall be conclusive in the absence of manifest error), and (ii) as long as such Lender Party shall be required to comply with any reserve ratio requirement or analogous requirement of any other central banking or financial regulatory authority imposed in respect of the maintenance of the Commitments or the funding of the Eurodollar Advances, such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal places) equal to the actual costs allocated to such Commitments or Advances by such Lender Party (as determined by such Lender Party in good faith, which determination shall be conclusive in the absence of manifest error), which in each case, shall be due and payable on each date on which interest is payable on such Advance.

Section 2.13 Payments and Computations.

(a) Payments. All payments to be made by the Borrower shall be made in immediately available funds without condition or deduction for any counterclaim, defense, recoupment or setoff; provided that the Borrower may setoff amounts owing to any Lender that is at such time a Defaulting Lender against Advances that such Defaulting Lender failed to fund to the Borrower under this Agreement (the “Unfunded Advances”) so long as (i) the Borrower shall have delivered prior written notice of such setoff to the Administrative Agent and such Defaulting Lender, (ii) the Advances made by the Non-Defaulting Lenders as part of the original Revolving Borrowing to which the Unfunded Advances applied shall still be outstanding, (iii) if such Defaulting Lender failed to fund Advances under more than one Revolving Borrowing, such setoff shall be applied in a manner satisfactory to the Administrative Agent, and (iv) upon the application of such setoff, the Unfunded Advances shall be deemed to have been made by such Defaulting Lender on the effective date of such setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed in Dollars and in Same Day Funds. Subject to Section 2.5(c), each payment of any Advance pursuant to this Section or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Revolving Borrowing are paid in whole or ratably in part.

(b) Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the applicable Lenders or the Issuing Lenders 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 Lenders, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the applicable Lenders or the Issuing Lenders, 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 Lender, in Same Day Funds 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 Overnight Rate. A notice of the Administrative Agent to any Lender or Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c) Payment Procedures. The Borrower shall make each payment of any amount under this Agreement and under any other Credit Document not later than 11:00 a.m. (Houston, Texas time) on the day when due in Dollars to the Administrative Agent at the Administrative Agent’s address (or such other location as the Administrative Agent shall designate in writing to the Borrower) in Same Day Funds. Without limiting the generality of the foregoing, the Administrative Agent may require that any payments due under this Agreement be made in the United States. The Administrative Agent will promptly thereafter, and in any event prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to any specific Lender Party pursuant to Sections 2.4, 2.10, 2.11, 2.12, 2.14, and 9.1 but after taking into account payments effected pursuant to Section 2.13(f)) in accordance with each Lender’s Applicable Percentage to the Lenders for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon receipt of other amounts due solely to the Administrative Agent, Issuing Lender, Swingline Lender, or a specific Lender, the Administrative Agent shall distribute such amounts to the appropriate party to be applied in accordance with the terms of this Agreement.

(d) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of Eurodollar Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Computations. All computations of interest and fees shall be made by the Administrative Agent on the basis of a year of 365/366 days for Base Rate Advances for which interest is calculated based on the Prime Rate and a year of 360 days for all other interest and fees, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent manifest error.

(f) Sharing of Payments, Etc. Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff, counterclaim or otherwise against the Borrower or any other Credit Party, obtain payment (voluntary or involuntary) in respect of any Advance or the participations in the Letter of Credit Obligations or in the Swingline Advances held by it, as a result of which the unpaid portion of its Advances shall be proportionately less than the unpaid portion of the Advances or the participations in the Letter of Credit Obligations or in the Swingline Advances held by any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Advances, the participations in the Letter of Credit Obligations and in the Swingline Advances held by it of such other Lender, so that the aggregate unpaid amount of the Advances and participations in Advances, Letter of Credit Obligations and Swingline Advances held by each Lender shall be in the same proportion to the aggregate unpaid amount of all Advances, Letter of Credit Obligations and Swingline Advances then outstanding as the amount of its Advances, and participations in Letter of Credit Obligations and Swingline Advances prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the amount of all Advances and participations in Letter of Credit Obligations and Swingline Advances, outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that if any such purchase or

purchases or adjustments shall be made pursuant to this Section 2.13 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Section 2.14 Taxes.

(a) Issuing Lender. For purposes of this Section 2.14, the term “Lender” includes any Issuing Lender.

(b) Payments Free of Taxes. Any and all payments by or on account of any obligation of any Credit Party under any Credit Document shall be made without deduction or withholding for any Taxes, except as required by applicable Legal Requirement. If any applicable Legal Requirement (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, then 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 Legal Requirement and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Credit 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) Payment of Other Taxes by Credit Parties. The Credit Parties shall timely pay to the relevant Governmental Authority in accordance with applicable Legal Requirement, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d) Indemnification by Credit Parties. The Credit Parties shall jointly and severally indemnify each Recipient, within 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, except as a result of the gross negligence or willful misconduct of the Recipient, 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 the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Credit Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Credit Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.6(c) 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 Credit 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 to such Lender under any Credit 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) Evidence of Payments. As soon as practicable after any payment of Taxes by any Credit Party to a Governmental Authority pursuant to this Section 2.14, such Credit Party shall deliver to the Administrative Agent the original or a certified copy of any available receipt issued by such Governmental Authority evidencing such payment, a copy of the return (if any) reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(g) Status of Lenders.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Credit Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or 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 the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Legal Requirement or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.14(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing,

(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 reasonable 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 Credit 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 Credit 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 F-1 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 the 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 substantially in the form of Exhibit F-2 or Exhibit F-3, 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 F-4 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 Legal Requirement 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 Legal Requirement 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 Credit 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 Legal Requirement and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable Legal Requirement (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) Treatment of Certain Refunds. 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 2.14 (including by the payment of additional amounts pursuant to this Section 2.14), 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 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. Notwithstanding anything to the contrary in this paragraph (h), in no event will the

indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph 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) Survival. Each party’s obligations under this Section 2.14 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 Credit Document.

Section 2.15 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.12, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement Lender. If any Lender requests compensation under Section 2.12, or if the Borrower is 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 2.14 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 2.15(a), or if any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and effort (and in the case of a Defaulting Lender, the Administrative Agent may) 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, and consents required by, Section 9.6), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.12 or Section 2.14) and obligations under this Agreement and the related Credit Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i) the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 9.6;

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Revolving Advances and participations in Letter of Credit Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.11) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments thereafter; and

(iv) such assignment does not conflict with applicable Legal Requirement.

A Lender shall not be required to make any such assignment or 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. Solely for purposes of effecting any assignment involving a Defaulting Lender under this Section 2.15 and to the extent permitted under applicable Legal Requirements, each Lender hereby designates and appoints the Administrative Agent as true and lawful agent and attorney-in-fact, with full power and authority, for and on behalf of and in the name of such Lender to execute, acknowledge and deliver the Assignment and Acceptance required hereunder if such Lender is a Defaulting Lender and such Lender shall be bound thereby as fully and effectively as if such Lender had personally executed, acknowledged and delivered the same. In lieu of the Borrower or the Administrative Agent replacing a Defaulting Lender as provided in this Section 2.15, the Borrower may terminate such Defaulting Lender’s applicable Commitment as provided in Section 2.1(b)(ii).

Section 2.16 Defaulting Lender.

(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 Legal Requirement:

(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 Majority 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 VII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 7.4 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 the Issuing Lender or Swingline Lender hereunder; third, to Cash Collateralize each Issuing Lender’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.3(k); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any loan hereunder 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 Advances under this Agreement and (y) Cash Collateralize each Issuing Lender’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 2.3(k); sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any Issuing Lender or the 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 by or on behalf of Borrower of the principal amount of any loans or Letter of Credit 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 3.1 were satisfied or waived, such payment shall be applied solely to pay the loans of, and Letter of Credit disbursements owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any loans of, or Letter of Credit disbursements owed to, such Defaulting Lender until such time as all Advances and funded and unfunded participations in Letter of Credit Obligations and Swingline Advances are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 2.16(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 2.16(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 Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive fees under Section 2.8(b)(i) 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 2.3(k).

(C) With respect to any fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower 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 Letter of Credit Obligations or Swingline Advances that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Lender and the Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Lender’s or the Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in Letter of Credit Obligations and Swingline Advances 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 3.1 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower 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 Outstandings of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s 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.

(v) Cash Collateral, Repayment of Swingline Advances. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under Legal Requirement, (x) first, prepay Swingline Advances in an amount equal to the Swingline Lender’s Fronting Exposure and (y) second, Cash

Collateralize each Issuing Lender’s Fronting Exposure in accordance with the procedures set forth in Section 2.3(k).

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and each Issuing Lender 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 Revolving Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit and Swingline Advances to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.16(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) Letters of Credit. So long as any Lender is a Defaulting Lender, no Issuing Lender 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.

(d) Swingline Advances. So long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to make any Swingline Advances unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

Section 4.6 True and Complete Disclosure. All written factual information (whether delivered before or after the date of this Agreement) prepared by or on behalf of the Parent or a Subsidiary and furnished to any Lender Party for purposes of or in connection with this Agreement, any other Credit Document or any transaction contemplated hereby or thereby is true and accurate in all material respects on the date as of which such information is dated or certified and not incomplete by omitting to state any material fact necessary to make such information (taken as a whole) not materially misleading at such time, in light of the circumstances under which they were made. There is no fact known to any Responsible Officer of the Parent on the date of this Agreement that has not been disclosed to the Administrative Agent that could reasonably be expected to result in a Material Adverse Change.

Section 4.7 Litigation. Except as set forth in Schedule 4.7, there are no actions, suits, or proceedings pending or, to the Borrower’s or the Parent’s knowledge, threatened against the Parent, the Borrower or any Subsidiary, at law, in equity, or in admiralty, or by or before any Governmental Authority, which could reasonably be expected to result in a Material Adverse Change; provided that this Section 4.7 does not apply with respect to Environmental Claims.

Neither the Parent nor any Subsidiary is a party to any indenture, loan or credit agreement or any lease or any other types of agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation the performance of or compliance with which could reasonably be expected to cause a Material Adverse Change.

ARTICLE VIII.

THE ADMINISTRATIVE AGENT AND ISSUING LENDERS

Section 8.1 Appointment and Authority. Each Lender, the Swingline Lender and each Issuing Lender hereby irrevocably (a) appoints Xxxxx Fargo to act on its behalf as the Administrative Agent hereunder and under the other Credit Documents, and (b) 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 VIII are solely for the benefit of the Lender Parties, and neither the Parent, the Borrower nor any other Credit 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 Credit Document (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.

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, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Parent, the Borrower or any other Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders. Xxxxx Fargo (and any successor acting as Administrative Agent) and its Affiliates may accept fees and other consideration from the Borrower, the Parent or any Affiliate of the Parent for services in connection with this Agreement or otherwise without having to account for the same to the Lenders or the Issuing Lenders.

Section 8.3 Exculpatory Provisions. The Administrative Agent (which term as used in this Section 8.3 shall include its Related Parties) shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

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

(b) 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 Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit 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 Credit 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

(c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, nor shall it be liable for the failure to disclose, any information relating to the Parent, the Borrower, any other Credit Party 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.

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 Majority 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 as provided in Sections 9.2 and 7.1) 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 not 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 the Borrower, a Lender, the Swingline Lender or an Issuing Lender. In the event that the Administrative Agent receives such a notice of the occurrence of a Default, the Administrative Agent shall (subject to Section 9.2) take such action with respect to such Default or Event of Default as shall reasonably be directed by the Majority Lenders, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action) with respect to such Default as it shall deem advisable in the best interest of the Lender Parties.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any recital, statement, warranty or representation (whether written or oral) made in or in connection with this Agreement or any other Credit 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 value, validity, enforceability, effectiveness, enforceability, sufficiency or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document, (v) the inspection of, or to inspect, the Property (including the books and records) of any Credit Party or any Subsidiary or Affiliate thereof, (vi) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent, or (vii) any litigation or collection proceedings (or to initiate or conduct any such litigation or proceedings) under any Credit Document unless requested by the Majority Lenders in writing and its receives indemnification satisfactory to it from the Lenders.

Section 8.4 Reliance by Administrative Agent, Swingline Lender and Issuing Lenders. 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, writing or other communication (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 Credit Extension or any Conversion or continuance of an Advance that by its terms must be fulfilled to the satisfaction of a Lender, the Swingline Lender or an Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender, the Swingline Lender or Issuing Lender unless the Administrative Agent shall have received notice to the contrary from such Lender, the Swingline Lender or Issuing Lender prior to the making of such Credit Extension or Conversion or continuance of an Advance. The Administrative Agent may consult with legal counsel (who may be counsel for the Parent or the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 8.5 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 Credit 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 shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 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 non-appealable 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 or Issuing Lender.

(a) The Administrative Agent and each Issuing Lender may at any time give notice of its resignation to the other Lender Parties and the Borrower. Upon receipt of any such notice of resignation, the Majority Lenders shall have the right, to appoint, as applicable, a successor Administrative Agent or a successor Issuing Lender, which shall be a Lender with the prior written consent of (i) the Borrower (which consent is not required if a Default or Event of Default has occurred and is continuing and which consent shall not be unreasonably withheld or delayed) and (ii) such successor Administrative Agent or successor Issuing Lender, as applicable. If no such successor Administrative Agent or Issuing Lender shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent or Issuing Lender gives notice of its resignation (or such earlier day as shall be agreed by the applicable Majority Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent or Issuing Lender, as applicable, may on behalf of the Lenders and Issuing Lenders,

appoint a successor agent or issuing lender meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation by the Administrative Agent or the Issuing Lender 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 Majority Lenders may, to the extent permitted by applicable Legal Requirement, with the prior written consent of the Borrower (which consent is not required if a Default or Event of Default has occurred and is continuing and which consent shall not be unreasonably withheld or delayed) (i) by notice in writing to such Person remove such Person as Administrative Agent and (ii) appoint a successor. If no such successor shall have been so appointed by applicable Majority Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the applicable Majority Lenders) (the “Removal Effective Date”), then 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) (i) the retiring or removed Administrative Agent or Issuing Lender, as applicable, shall be discharged from its duties and obligations as Administrative Agent and Issuing Lender hereunder and under the other Credit Documents (except that (v) in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the Issuing Lenders under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed and (z) the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit) and (ii) all payments, communications and determinations provided to be made by, to or through the retiring or removed Administrative Agent or Issuing Lender, as applicable, shall instead be made by or to each applicable class of Lenders, until such time as the Majority Lenders appoint a successor Administrative Agent or Issuing Lender as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent or Issuing Lender 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 or Issuing Lender, as applicable, and the retiring or removed Administrative Agent or Issuing Lender, as applicable, shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents. The fees payable by the Borrower to a successor Administrative Agent or Issuing Lender, as applicable shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s or Issuing Lender’s resignation or removal hereunder and under the other Credit Documents, the provisions of this Article and Sections 9.1(b) and (d), Section 8.9 and Section 2.3(h) shall continue in effect for the benefit of such retiring or removed Administrative Agent and Issuing Lender, 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 or Issuing Lender, as applicable, was acting as Administrative Agent or Issuing Lender.

(d) The Swingline Lender may resign at any time by giving 30 days’ prior notice to the Administrative Agent, the Lenders and the Borrower. After the resignation of the Swingline Lender hereunder, the retiring Swingline Lender shall remain a party hereto and shall continue to have all the rights and obligations of the Swingline Lender under this Agreement and the other Credit Documents with respect to Swingline Advances made by it prior to such resignation, but shall not be required to make any additional Swingline Advances. Upon such notice of resignation, the Borrower shall have the right to designate any other Lender as the Swingline Lender with the consent of such Lender so long as operational matters related to the funding of Advances have been adequately addressed to the reasonable satisfaction of such new Swingline Lender and the Administrative Agent (if such new Swingline Lender

and the Administrative Agent are not the same Person). Upon such notice of resignation, the Borrower shall (so long as no Default or Event of Default has occurred and is continuing) also have the right, if the resigning Swingline Lender and the Administrative Agent are the same Person, to remove the Administrative Agent by notice in writing to the Administrative Agent and each Lender. Upon such removal of the Administrative Agent, the Majority Lenders may, to the extent permitted by applicable Legal Requirement, with the prior written consent of the Borrower (which shall not be unreasonably withheld or delayed), appoint a successor. If no such successor shall have been so appointed by applicable Majority Lenders, and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the applicable Majority Lenders) (the “Replacement Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Replacement Effective Date.

Section 8.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender Party acknowledges and agrees that it has, independently and without reliance upon the Administrative Agent or any other Lender Party 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 Party also acknowledges and agrees that it will, independently and without reliance upon the Administrative Agent or any other Lender Party 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 Credit Document or any related agreement or any document furnished hereunder or thereunder.

All obligations of the Borrower provided for in Sections 2.11, 2.12, 2.14(c), and 9.1 and all of the obligations of the Lenders in Section 8.9 and Section 9.8 shall survive any termination of this Agreement, repayment in full of the Obligations, and termination or expiration of all Letters of Credit.

Section 9.5 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, except that neither the Borrower nor any other Credit Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender Party and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (a) to an Eligible Assignee in accordance with the provisions of Section 9.6(a), (b) by way of participation in accordance with the provisions of Section 9.6(d) or (c) by way of pledge or assignment of a security interest subject to the restrictions of Section 9.6(e) (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in Section 9.6(c) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and each Lender) any legal or equitable right, remedy or claim under or by reason of this Agreement.

Section 9.6 Lender Assignments and Participations.

(a) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Advances at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Advances under such Commitment at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Advances outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Advances 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 $10,000,000, unless the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met;

(ii) 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 applicable Class of Advances or the Commitment assigned;

(iii) any assignment of a Commitment must be approved by the Administrative Agent and the Issuing Lenders unless the Person that is the proposed assignee is itself a Lender with a Revolving Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(iv) 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 (which fee may be waived by the Administrative Agent in its sole discretion) and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (b) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible 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 2.11, 2.12, 2.14(c) and 9.1 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 (c) of this Section.

(b) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Commitments of, and principal amounts (and stated interest) of the Advances 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 Borrower and the Lender Parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. Borrower hereby agrees that the Administrative Agent, as its agent solely for the purpose set forth above thin this clause (b), shall not be subject to any fiduciary or other implied duties, all of which are hereby waived by the Borrower.

(c) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower, the Parent, any other Credit Party or the Administrative Agent, sell participations to any Person (other than a natural person or the Parent, the Borrower or any of the Parent’s Affiliates or other Subsidiaries) (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 Advances 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 Borrower and the Lender Parties shall continue to deal solely and directly with such Lender Party in connection with such Lender Party’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity provided under Section 8.9 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 to approve any amendment, modification or waiver of any provision of this Agreement; 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 clauses (a), (b), (c) or (d) of this Section 9.6 (that adversely affects such Participant). Subject to paragraph (d) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of, and subject to the requirements of, Sections 2.11, 2.12 and 2.14 (it being understood that the documentation required under Section 2.14(g) 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 (a) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 7.4 as though it were a Lender, provided such Participant agrees to be subject to Section 2.13(f) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, 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 Advances or other obligations under the Credit 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 Credit 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. Borrower hereby agrees that each Lender acting as its agent solely for

the purpose set forth above in this clause (c), shall not subject such Lender to any fiduciary or other implied duties, all of which are hereby waived by the Borrower.

(d) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 2.12 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.14 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.14, in which case Section 2.14 shall be applied as if such Participant had become a Lender and had acquired its interest by assignment pursuant to paragraph (a) of this Section; provided that, in no event shall such Participant be entitled to receive any greater payment under Section 2.14 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant.

(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 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) Information. Any Lender may furnish any information concerning the Credit Parties or any of their Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants) subject to the provisions of Section 9.8.

(g) 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 the Borrower and the Administrative Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (i) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Lenders, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (ii) acquire (and fund as appropriate) its full pro rata share of all Advances and participations in Letters of Credit and Swingline Advances 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.

Section 9.7 Notices, Etc.

(a) Notices Generally. Except in the case of notices and other communications expressly permitted to be given by telephone (and except as provided in paragraph (b) below), all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by facsimile as follows: (i) if to the Borrower or any other Credit Party, at the applicable address (or facsimile numbers) set forth on Schedule III; (ii) if to the Administrative Agent or the Swingline Lender, at the applicable address (or facsimile numbers) set forth on Schedule III; and (iii) if to a Lender or an Issuing Lender, to it at its address (or

facsimile number) set forth in its Administrative Questionnaire. Notices sent by hand or overnight courier service, or mailed by certified or registered mail, shall be deemed to have been given when received; notices sent by facsimile shall be deemed to have been given when sent (except that, if not given during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next business day for the recipient). Notices delivered through electronic communications to the extent provided in paragraph (b) below, shall be effective as provided in said paragraph (b).

(b) Electronic Communications.

(i) The Borrower, the Parent and the Lenders agree that the Administrative Agent may make any material delivered by the Borrower, the Parent or any other Credit Party to the Administrative Agent, as well as any amendments, waivers, consents, and other written information, documents, instruments and other materials relating to the Parent, the Borrower, any other Subsidiary, or any other materials or matters relating to this Agreement, the Notes or any of the transactions contemplated hereby (collectively, the “Communications”) available to the Lenders by posting such notices on an electronic delivery system (which may be provided by the Administrative Agent, an Affiliate of the Administrative Agent, or any Person that is not an Affiliate of the Administrative Agent), such as IntraLinks, Syndtrak or a substantially similar electronic system (the “Platform”); provided that the foregoing shall not apply to notices to any Lender or Issuing Lender pursuant to Article II if such Lender or Issuing Lender, as applicable, has notified the Administrative Agent that it is incapable of receiving notices under such Article by electronic communication. The Borrower and the Parent each acknowledges that (i) the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution, (ii) the Platform is provided “as is” and “as available” and (iii) none of the Administrative Agent nor any of its Affiliates warrants the accuracy, completeness, timeliness, sufficiency, or sequencing of the Communications posted on the Platform. The Administrative Agent and its Affiliates expressly disclaim with respect to the Platform any liability for errors in transmission, incorrect or incomplete downloading, delays in posting or delivery, or problems accessing the Communications posted on the Platform and any liability for any losses, costs, expenses or liabilities that may be suffered or incurred in connection with the Platform. 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 the Administrative Agent or any of its Affiliates in connection with the Platform. In no event shall the Administrative Agent or any of its Related Parties have any liability to the Borrower or the other Credit Parties, any Lender Party 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 Credit Party’s or any Lender Party’s transmission of communications through the Platform except to the extent of such Credit Party’s direct damages arising from the gross negligence or willful misconduct of the Administrative Agent (as determined by a court of competent jurisdiction in a final non-appealable judgment) in providing Platform login credentials to a Person to whom it is not otherwise permitted to disclose the Information under Section 9.8.

(ii) Each Lender agrees that notice to it (as provided in the next sentence) (a “Notice”) specifying that any Communication has been posted to the Platform shall for purposes of this Agreement constitute effective delivery to such Lender of such information, documents or other materials comprising such Communication. Each Lender agrees (i) to notify, on or before the date such Lender becomes a party to this Agreement, the Administrative Agent in writing of such Lender’s e-mail address to which a Notice may be sent (and from time to time thereafter to ensure that the Agent has on record an effective e-mail address for such Lender) and (ii) that any Notice may be sent to such e-mail address.

(c) Change of Address, Etc. Any party hereto may change its address or facsimile number for notices and other communications hereunder by notice to the other parties hereto.

Section 9.8 Confidentiality. The Administrative Agent, each Lender and each Issuing Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (the “Representatives”) (it being understood that the Representative 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 purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit 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 the Parent, the Borrower or any other Subsidiary and their respective obligations, (g) with the consent of the Parent or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to any Lender Party or any of their respective Affiliates on a nonconfidential basis from a source other than a Credit Party. For purposes of this Section, “Information” means all information received from the Parent, the Borrower or any other Subsidiary relating to the Parent, the Borrower or any other Subsidiary or any of their respective businesses, other than any such information that is available to Lender Party on a nonconfidential basis prior to disclosure by the Parent, the Borrower or any other Subsidiary. 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. The Administrative Agent, each Lender and each Issuing Lender agrees to be responsible for any breaches of this Section 9.8 by its Representatives.

Section 9.9 Business Loans. The Borrower warrants and represents that the Obligations are and shall be for business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect.

Section 9.10 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable laws of the State of Texas, the United States from time to time in effect, and any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement. In furtherance thereof, the Lenders and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes of this Agreement and all other Credit Documents, “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement or any other Credit Document; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Obligations, include amounts which by

applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal of the Obligations owing to such Lender (or if all such Obligations shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Obligations are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Obligations (or, if the applicable Obligations shall have been paid in full, refunded to the Borrower of such interest). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Advances all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations. The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

Section 9.11 Usury Recapture. In the event the rate of interest chargeable under this Agreement or any other Credit Document at any time is greater than the Maximum Rate, the unpaid principal amount of the Obligations shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Obligations equals the amount of interest which would have been paid or accrued on the Advances if the stated rates of interest set forth in this Agreement or applicable Credit Document had at all times been in effect. In the event, upon payment in full of the Obligations, the total amount of interest paid or accrued under the terms of this Agreement and the Obligations is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement or such Credit Document had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable law, pay the Administrative Agent for the account of the applicable Lender Party an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on Obligations owed to it if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Obligations if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid under this Agreement or any Credit Document on Obligations owed to it. In the event the any Lender Party ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Obligations, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

Section 9.12 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower or any other Credit Party is made to any Lender Party, or any Lender Party exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any Lender Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender and each Issuing Lender severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect, in the applicable currency of such recovery or payment. The obligations of the Lenders, the Swingline Lender and the Issuing Lenders under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

Section 9.13 Governing Law; Submission to Jurisdiction.

(a) Governing Law. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein) shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Xxx. Art. 0000, Xx. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect.

(b) Submission to Jurisdiction. The Parent and the Borrower irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Federal or Texas state court sitting in Xxxxxx County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Credit Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas 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 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.

Section 9.15 Waiver of Jury. EACH PARTY HERETO HEREBY ACKNOWLEDGES THAT IT HAS BEEN REPRESENTED BY AND HAS CONSULTED WITH COUNSEL OF ITS CHOICE, AND HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY 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 CREDIT 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 PERSON 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 AND THE OTHER CREDIT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

IN EXECUTING THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS, THE BORROWER HEREBY REPRESENTS AND WARRANTS THAT IT IS NOT RELYING ON

ANY STATEMENT OR REPRESENTATION OTHER THAN THOSE IN THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND IS RELYING UPON ITS OWN JUDGEMENT AND ADVICE OF ITS ATTORNEYS.

FORM OF GUARANTY

This Guaranty dated as of May [·], 2012 (“Guaranty”) is among each of the undersigned (individually a “Guarantor” and collectively, the “Guarantors”) in favor of Xxxxx Fargo Bank, National Association, as Administrative Agent for the ratable benefit of the Lender Parties (as defined in the Credit Agreement referred to below).

INTRODUCTION

X. Xxxxxxxxx & Xxxxx International Drilling Co., a Delaware corporation (the “Borrower”), the lenders party thereto from time to time, and Xxxxx Fargo Bank, National Association, as Administrative Agent, Swingline Lender, and Issuing Lender, are parties to that certain Credit Agreement dated as of May 25, 2012 (the “Credit Agreement”; the defined terms of which are used herein unless otherwise defined herein).

B. It is a requirement under the Credit Agreement that each Guarantor shall guarantee the due payment and performance of all Obligations.

C. Each Guarantor is either the parent company of the Borrower or a Subsidiary of the Borrower and will derive substantial direct and indirect benefit from the transactions contemplated by the Credit Agreement and the other Credit Documents.

D. Each Guarantor is executing and delivering this Guaranty (a) to induce the Lenders to provide and continue to provide Advances under the Credit Agreement, (b) to induce the Issuing Lenders to provide and continue to provide Letters of Credit under the Credit Agreement, and (c) intending it to be a legal, valid, binding, enforceable and continuing obligation of each Guarantor.

NOW, THEREFORE, in consideration of the premises, each Guarantor, for the benefit of the Lender Parties, does hereby further agree as follows:

AGREEMENT

1. Guaranty. Each Guarantor hereby absolutely and unconditionally guarantees, as a guaranty of payment and performance and not merely as a guaranty of collection, prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of any and all existing and future indebtedness and liabilities of every kind, nature and character, direct or indirect, absolute or contingent, liquidated or unliquidated, voluntary or involuntary and whether for principal, interest, premiums, fees indemnities, damages, costs, expenses or otherwise, of the Borrower to the Lender Parties under the Credit Documents (including all renewals, extensions, amendments, refinancings and other modifications thereof and all costs, attorneys’ fees and expenses incurred by the Lender Parties in connection with the collection or enforcement thereof), and whether recovery upon such indebtedness and liabilities may be or hereafter become unenforceable or shall be an allowed or disallowed claim under any proceeding or case commenced by or against each Guarantor or the Borrower under Debtor Relief Laws, and including interest that accrues after the commencement by or against the Borrower of any proceeding under any Debtor Relief Laws (collectively, the “Guaranteed Obligations”). Any Lender Party’s books and records showing the amount of the Guaranteed Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon such Guarantor and conclusive for the purpose of establishing the amount of the Guaranteed Obligations. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability

Form of Exhibit C

of the Guaranteed Obligations or any instrument or agreement evidencing any Guaranteed Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Guaranteed Obligations which might otherwise constitute a defense to the obligations of a Guarantor under this Guaranty, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing. Anything contained herein to the contrary notwithstanding, the obligations of each Guarantor hereunder at any time shall be limited to an 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 the Bankruptcy Code (Title 11, United States Code) or any comparable provisions of any similar federal or state law.

2. No Setoff or Deductions; Taxes; Payments. Each Guarantor represents and warrants that it is organized and resident in the United States of America. Each Guarantor shall make all payments hereunder without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless such Guarantor is compelled by law to make such deduction or withholding. If any such obligation (other than Excluded Taxes) is imposed upon such Guarantor with respect to any amount payable by it hereunder, such Guarantor will pay to such Lender Party, on the date on which such amount is due and payable hereunder, such additional amount in U.S. dollars as shall be necessary to enable such Lender Party to receive the same net amount which such Lender Party would have received on such due date had no such obligation been imposed upon such Guarantor. Each Guarantor will deliver promptly to the applicable Lender Party certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by such Guarantor hereunder. The obligations of each Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty.

3. Rights of Lender. Each Guarantor consents and agrees that the Lender Parties may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) amend, extend, renew, compromise, discharge, accelerate in accordance with the Credit Agreement or otherwise change the time for payment or the terms of the Guaranteed Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Guaranteed Obligations; (c) to the extent permitted by law, apply such security and direct the order or manner of sale thereof as the Lender in its sole discretion may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Guaranteed Obligations. Without limiting the generality of the foregoing, each Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of a Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of a Guarantor.

4. Certain Waivers. Each Guarantor waives (a) any defense arising by reason of any disability or other defense of the Borrower or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of the Lender) of the liability of the Borrower; (b) any defense based on any claim that a Guarantor’s obligations exceed or are more burdensome than those of the Borrower; (c) the benefit of any statute of limitations affecting a Guarantor’s liability hereunder; (d) any right to require the Lender Parties to proceed against the Borrower, proceed against or exhaust any security for the Obligations, or pursue any other remedy in any Lender Party’s power whatsoever; (e) any benefit of and any right to participate in any security now or hereafter held by any Lender Party; and (f) to the fullest extent permitted by law, any and all other defenses or benefits that may be derived from or afforded by applicable law limiting the liability of or exonerating guarantors or sureties. Each Guarantor expressly waives all setoffs and counterclaims and all presentments, demands for payment or

performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Guaranteed Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Guaranteed Obligations, including but not limited to the benefits of Chapter 34 of the Texas Business and Commerce Code, §17.001 of the Texas Civil Practice and Remedies Code, and Rule 31 of the Texas Rules of Civil Procedure, or any similar statute.

5. Obligations Independent. The obligations of each Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Guaranteed Obligations and the obligations of any other guarantor, and a separate action may be brought against each Guarantor to enforce this Guaranty whether or not the Borrower or any other person or entity is joined as a party.

6. Subrogation. Each Guarantor shall not exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Guaranteed Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full and any commitments of the Lender Parties or facilities provided by the Lender Parties with respect to the Guaranteed Obligations are terminated. If any amounts are paid to a Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit of the Lender Parties and shall forthwith be paid to the Administrative Agent for the benefit of the Lender Parties to reduce the amount of the Guaranteed Obligations, whether matured or unmatured.

7. Termination; Reinstatement. This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall remain in full force and effect until all Guaranteed Obligations and any other amounts payable under this Guaranty are indefeasibly paid in full in cash, all Letters of Credit have expired, terminated or been cash collateralized and the Commitments of the Lender Parties with respect to the Guaranteed Obligations are terminated. Notwithstanding the foregoing, this Guaranty shall continue in full force and effect or be revived, as the case may be, if any payment by or on behalf of the Borrower or a Guarantor is made, or any Lender Party exercises its right of setoff, in respect of the Guaranteed Obligations and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by a Lender Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not any Lender Party is in possession of or has released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of each Guarantor under this paragraph shall survive termination of this Guaranty.

8. Subordination. Each Guarantor hereby subordinates the payment of all obligations and indebtedness of the Borrower owing to each Guarantor, whether now existing or hereafter arising, including but not limited to any obligation of the Borrower to each Guarantor as subrogee of the Lender Parties or resulting from each Guarantor’s performance under this Guaranty, to the indefeasible payment in full in cash of all Guaranteed Obligations. If the Administrative Agent so requests, any such obligation or indebtedness of the Borrower to each Guarantor shall be enforced and performance received by each Guarantor as trustee for the Administrative Agent for the benefit of the Lender Parties and the proceeds thereof shall be paid over to the Administrative Agent for the benefit of the Lender Parties on account of the Guaranteed Obligations, but without reducing or affecting in any manner the liability of each Guarantor under this Guaranty.

9. Stay of Acceleration. In the event that acceleration of the time for payment of any of the Guaranteed Obligations is stayed, in connection with any case commenced by or against a Guarantor or

the Borrower under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by each Guarantor immediately upon demand by the Administrative Agent.

10. Expenses. Each Guarantor shall pay on demand all out-of-pocket expenses (including attorneys’ fees and expenses and the allocated cost and disbursements of internal legal counsel) in any way relating to the enforcement or protection of the Administrative Agent or any Lender Party’s rights under this Guaranty or in respect of the Guaranteed Obligations, including any incurred during any “workout” or restructuring in respect of the Guaranteed Obligations and any incurred in the preservation, protection or enforcement of any rights of the Administrative Agent or any Lender Party in any proceeding any Debtor Relief Laws. The obligations of each Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty.

11. Miscellaneous. No provision of this Guaranty may be waived, amended, supplemented or modified, except by a written instrument executed by each Guarantor and each other Person required under Section 9.2 of the Credit Agreement. Notwithstanding the foregoing, this Guaranty may be supplemented to add additional Persons as additional Guarantors, either by such Person executing a joinder or supplement to this Guaranty without action by any other Person. No failure by the Administrative Agent or any Lender Party to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy or power hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies herein provided are cumulative and not exclusive of any remedies provided by law or in equity. The unenforceability or invalidity of any provision of this Guaranty shall not affect the enforceability or validity of any other provision herein. Unless otherwise agreed by the Administrative Agent, the Majority Lenders and each Guarantor in writing, this Guaranty is not intended to supersede or otherwise affect any other guaranty now or hereafter given by each Guarantor for the benefit of the Lender Parties or any term or provision thereof.

12. Condition of Borrower. Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrower and any other guarantor such information concerning the financial condition, business and operations of the Borrower and any such other guarantor as each Guarantor requires, and that the Lender Parties have no duty, and each Guarantor is not relying on the Administrative Agent or any other Lender Party at any time, to disclose to each Guarantor any information relating to the business, operations or financial condition of the Borrower or any other guarantor (each guarantor waiving any duty on the part of the Administrative Agent or any Lender Party to disclose such information and any defense relating to the failure to provide the same).

13. Representations and Warranties. Each Guarantor represents and warrants that (a) it is duly organized and in good standing under the laws of the jurisdiction of its organization and has full capacity and right to make and perform this Guaranty, and all necessary authority has been obtained; (b) this Guaranty constitutes its legal, valid and binding obligation enforceable in accordance with its terms; (c) the making and performance of this Guaranty does not and will not violate the provisions of any applicable law, regulation or order, and does not and will not result in the breach of, or constitute a default or require any consent under, any material agreement, instrument, or document to which it is a party or by which it or any of its property may be bound or affected; and (d) all consents, approvals, licenses and authorizations of, and filings and registrations with, any governmental authority required under applicable law and regulations for the making and performance of this Guaranty have been obtained or made and are in full force and effect.

This Guaranty shall (a) bind each Guarantor and its successors and assigns, provided that no Guarantor may not assign its rights or obligations under this Guaranty without the prior written consent of the Administrative Agent and the Majority Lenders or the Lenders, as required by the Credit Agreement (and any attempted assignment without such consent shall be void), and (b) inure to the benefit of the Administrative Agent, and the other Lender Parties and their respective successors and assigns and each Lender Party may, without notice to any Guarantor and without affecting any such Guarantor’s obligations hereunder, assign, sell or grant participations in the Guaranteed Obligations and this Guaranty, in whole or in part, to the extent permitted by the Credit Agreement. Each Guarantor irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Federal or Texas state court sitting in Xxxxxx County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Guaranty or any other Credit Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas State court or, to the fullest extent permitted by applicable law, in such Federal court. Each of the Guarantors agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Guaranty or in any other Credit Document shall affect any right that any Lender Party may otherwise have to bring any action or proceeding relating to this Guaranty or any other Credit Document against any Guarantor or its properties in the courts of any jurisdiction. All notices and other communications to any Guarantor under this Guaranty shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopier to such Guarantor at the address for the Borrower set forth in the Credit Agreement or at such other address in the United States as may be specified by the Guarantor in a written notice delivered to the Administrative Agent at its office specified in the Credit Agreement or such other office as the Administrative Agent may designate for such purpose from time to time in a written notice to such Guarantor.

16. WAIVER OF JURY TRIAL; FINAL AGREEMENT. EACH PARTY HERETO HEREBY ACKNOWLEDGES THAT IT HAS BEEN REPRESENTED BY AND HAS CONSULTED WITH COUNSEL OF ITS CHOICE, AND HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY 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 CREDIT 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 PERSON 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 AND THE OTHER CREDIT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Litigation

A. The Borrower, the Parent and/or their Affiliates are involved in the following matter as disclosed in the Parent’s Form 10-Q filed with the SEC on May 4, 2012:

“Pending Investigation by the U.S. Attorney.

In May 2010, one of our employees reported certain possible choke manifold testing irregularities at one offshore platform rig. Operations were promptly suspended on that rig after receiving the employee’s report. The Minerals Management Service (now known as the Bureau of Safety and Environmental Enforcement) was promptly notified of the employee’s report and it conducted an initial investigation of this matter. Upon conclusion of the initial investigation, we were permitted to resume normal operations on the rig. Also, we promptly commenced an internal investigation of the employee’s allegations. Our internal investigation found that certain employees on the rig failed to follow our policies and procedures, which resulted in termination of those employees. There were no spills or discharges to the environment.

The U.S. Attorney for the Eastern District of Louisiana has commenced a grand jury investigation, which is ongoing. We received, and have complied with, a subpoena for documents in connection with that investigation. Certain of our current and former employees have been interviewed by the government or have testified before the grand jury. In late April 2011, the Company was advised that it is a subject of this investigation.

Xx. Xxxxxx Xxxxxx, former offshore platform rig manager, recently pleaded guilty to one felony charge of making false statements to a federal investigator concerning his participation in the testing irregularities that were reported in May 2010. Sentencing is currently scheduled for late summer 2012. Xx. Xxxxxx’x employment was terminated by the Company in June 2010. We continue to cooperate with this government investigation. Although we presently believe that this matter will not have a material adverse effect on the Company, we can provide no assurances as to the timing or eventual outcome of this investigation.”

B. The Borrower, the Parent and/or their Affiliates are involved in the following matters as disclosed in the Parent’s Form 10-Q filed with the SEC on November 23, 2011:

“Venezuela Expropriation.

Our wholly-owned subsidiaries, Helmerich & Xxxxx International Drilling Co. and Helmerich & Xxxxx de Venezuela, C.A. filed a lawsuit in the United States District Court for the District of Columbia on September 23, 2011 against the Bolivarian Republic of Venezuela, Petroleos de Venezuela, S.A. (“Petroleo”) and PDVSA Petroleo, S.A. (“PDVSA”). We are seeking damages for the taking of our Venezuelan drilling business in violation of international law and for breach of contract. Additionally, we are participating in two arbitrations against third parties not affiliated with the Venezuelan government, Petroleo or PDVSA in an attempt to collect an aggregate $75 million relating to the seizure of our property in Venezuela. While there exists the possibility of realizing a recovery, we are currently unable to determine the timing or amounts we may receive, if any, or the likelihood of recovery.”

Pension Plan Assets

As of September 30, 2011, the accumulated benefit obligation for the Helmerich & Xxxxx, Inc. Employee Retirement Plan (“Pension Plan”) was $104.9 million as compared to Pension Plan assets of $67.3 million.
