(a) Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of LIBOR Loans shall be made upon the Borrower Representative’s irrevocable notice (and if in writing, in the form of the Loan Notice) to the Administrative Agent, which may be delivered by telephone or e-mail request (or such other means as may be agreed upon by the Administrative Agent in its sole discretion).

Each telephonic notice by the Borrower Representative pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of a written Loan Notice, appropriately completed and executed by a Responsible Officer of the Borrower Representative.

Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable LIBOR Loans. If the Borrower Representative requests a Borrowing of, conversion to, or continuation of LIBOR Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one (1) month.

Borrowing, each Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the applicable Loan Notice without setoff, defense, counterclaim or claims in recoupment.

(c) Except as otherwise provided herein, a LIBOR Loan may be continued or converted only on the last day of the Interest Period for such LIBOR Loan. During the existence of a Default or an Event of Default, no Loans may be requested as, converted to or continued as LIBOR Loans without the consent of the Administrative Agent or Required Lenders, and the Administrative Agent or Required Lenders may demand that any or all of the then outstanding LIBOR Loans be converted immediately to Base Rate Loans.

(d) The Administrative Agent shall promptly notify the Borrower Representative and the Lenders of the interest rate applicable to any Interest Period for LIBOR Loans upon determination of such interest rate. The determination of the LIBO Rate by the Administrative Agent shall be conclusive in the absence of manifest error.

(i) Should a Borrower wish to have a Letter of Credit issued or an existing Letter of Credit amended (including any increase in the amount thereof or extension of the expiry date thereof), Borrower Representative shall deliver to the Administrative Agent a Notice of L/C Credit Event at least five (5) Business Days before the proposed date of issuance or amendment.

(ii) Each L/C Issuer that is a party to this Agreement shall give the Administrative Agent prompt written notice (and Borrowers shall cause each L/C Issuer not a party to this Agreement to give the Administrative Agent prompt written notice) of each issuance or amendment of a Letter of Credit, each payment made by such L/C Issuer in respect of such Letter of Credit issued by it, and any other information requested by the Administrative Agent with respect to such Letter of Credit or amendment.

(c) Letter of Credit Fee. Borrowers shall pay to Administrative Agent, for the benefit of the Revolving Lenders, a letter of credit fee with respect to the Letter of Credit Liabilities for each Letter of Credit, computed for each day from the date of issuance of such Letter of Credit to the date that is the last day a drawing is available under such Letter of Credit, at a rate per annum equal to the Applicable Margin then applicable to Letters of Credit (the “Letter of Credit Fee”) times the daily maximum amount available to be drawn under such Letter of Credit (whether or not such maximum amount is then in effect under such Letter of Credit); provided, however, any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the L/C Issuer (or the Support Provider, as the case may be) pursuant to this Section 2.03 shall be payable, to the maximum extent permitted by applicable Law, to the other Revolving Lenders in accordance with the upward adjustments in their respective Pro Rata Share allocable to such Letter of Credit pursuant to Section 2.16(d), with the balance of such fee, if any, payable to the L/C Issuer (or the Support Provider, as the case may be) for its own account. Letter of Credit Fees shall be (i) computed on a quarterly basis in arrears and (ii) due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of

Mesa Credit and Guaranty Agreement —Page 42

Credit, on the Revolving Loan Maturity Date and thereafter on demand. Notwithstanding anything to the contrary contained herein, while an Event of Default exists, all Letter of Credit Fees shall accrue at the Default Rate. In addition, Borrowers shall pay promptly to the L/C Issuer (or reimburse the Support Provider for) any other fees, costs or expenses that it may charge in connection with any Letter of Credit.

(d) Reimbursement Obligations of Borrowers, Reimbursement Loans and Lender Participations. (i) If an L/C Issuer shall make a payment under a Letter of Credit or a Support Provider shall make a payment under a related Support Agreement, L/C Issuer or the Support Provider, as applicable, shall notify the Borrower Representative thereof. Not later than 11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of Credit or by the Support Provider under a Support Agreement, so long as the Borrower Representative has received telephonic notice of such payment prior to 10:00 a.m. on such date, and otherwise on the following Business Day, the applicable Borrowers shall promptly (but in any event on the same day) satisfy its Reimbursement Obligation by paying to the L/C Issuer or Support Provider (or to the Administrative Agent for the account of the L/C Issuer or Support Provider), as applicable, the full outstanding amount of such Unreimbursed Amount. Such Borrower shall also pay interest, on demand, on all Unreimbursed Amounts for each day until such Unreimbursed Amount is satisfied at a rate per annum equal to the sum of two percent (2%) plus the interest rate applicable to Revolving Loans (which are Base Rate Loans) for such day.

(ii) If any Borrower fails to pay its Reimbursement Obligation when due, the Borrower Representative shall be deemed to have immediately requested that Revolving Lenders make a Revolving Loan (a “Reimbursement Loan”), which shall be a Base Rate Loan, in a principal amount equal to the amount of such Unreimbursed Amount, the proceeds of which shall be applied to satisfy such Reimbursement Obligation. Administrative Agent shall promptly notify Revolving Lenders of any such deemed request and each Revolving Lender shall make available to Administrative Agent not later than 12:00 p.m. on the Business Day following such notification from Administrative Agent such Revolving Lender’s Pro Rata Share of such Revolving Loan. Each Revolving Lender hereby absolutely and unconditionally agrees to fund such Revolving Lender’s Pro Rata Share of the Reimbursement Loan, unaffected by any circumstance whatsoever, including without limitation (A) the occurrence and continuance of a Default or an Event of Default (but the funding of such a Revolving Loan shall not act as a cure or waiver of any Default or Event of Default other than the non-payment of such Unreimbursed Amount), (B) the fact that, whether before or after giving effect to the making of any such Revolving Loan, the Revolving Exposure exceeds or will exceed the Revolving Commitment, (C) the surrender or impairment of any security for the performance or observance of any of the terms of this Agreement, or (D) the failure of any condition in Article 4 to have been satisfied. Administrative Agent shall apply the gross proceeds of each such Revolving Loan in satisfaction of such Borrowers’ Reimbursement Obligation.

(iii) Concurrently with the issuance of each Support Agreement and Letter of Credit, each such Revolving Lender shall be deemed to have purchased and received, without recourse or warranty, an undivided interest and participation, to the extent of such Lender’s Pro Rata Share of the Revolving Commitment, in and to the

Mesa Credit and Guaranty Agreement —Page 43

liabilities and obligations in respect of such Letters of Credit and Support Agreements and the corresponding Reimbursement Obligations and Unreimbursed Amounts which may arise therefrom. Such Lenders’ participation obligation shall be absolute and unconditional and shall not be affected by any circumstances whatsoever. If, notwithstanding the provision of Section 2.03(d)(i) or (E), any portion of an Unreimbursed Amount remains outstanding (whether due to Borrowers failing to honor their Reimbursement Obligation, or if a Reimbursement Loan cannot for any reason be made, or otherwise) or if any reimbursement received by Support Provider or any L/C Issuer from any Borrower is or must be returned or rescinded upon or during any bankruptcy or reorganization of any Loan Party or otherwise (including any Revolving Loan made pursuant to Section 2.03(d)(ii1), each Revolving Lender shall be irrevocably and unconditionally obligated to fund its participation in such Unreimbursed Amount by paying to Administrative Agent for the account of the Support Provider or L/C Issuer, as applicable, its Pro Rata Share of such Unreimbursed Amount. To the extent any such Revolving Lender shall not have made such amount available to Administrative Agent, as applicable, by 12:00 p.m. on the Business Day on which such Lender receives such notice from Administrative Agent, (A) such Lender shall pay interest on such amount to Administrative Agent on demand accruing daily at the Federal Funds Rate, for the first three (3) days following such Lender’s receipt of such notice, and thereafter at the Base Rate plus the Applicable Margin in respect of Revolving Loans that are Base Rate Loans and (B) the Administrative Agent may apply any subsequent payment that such Lender otherwise is entitled to receive under this Agreement to the satisfaction of such Lender’s obligation. Any Revolving Lender’s failure to fund its participation amount shall not relieve any other Lender of its obligation hereunder to fund such participation, but no Revolving Lender shall be responsible for the failure of any other Lender to fund its participation.

(iv) Notwithstanding the foregoing, payment of any such Lender’s participation described in Section 2.03(d)(iii), and further disbursement of such payment to the L/C Issuer or Support Provider, shall in no way extinguish the Borrowers’ related Reimbursement Obligation and any such Reimbursement Obligation not paid by Borrower or refinanced by Reimbursement Loans shall be due and payable on demand together with interest as described in Section 2.03(d)(i).

(e) Repayment to Lenders. (i) Until a Lender funds its Reimbursement Loan or participation pursuant to Section 2.03(d), interest with respect to any Unreimbursed Amount shall be for the account of the L/C Issuer or Support Provider, as the case may be. Once the Administrative Agent has received from any Lender such Lender’s portion of the Reimbursement Loan or participation, the Administrative Agent shall distribute to such Lender (in the same funds as those received by the Administrative Agent, and whether such funds are directly from the Borrowers or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), such Lender’s Pro Rata Share of any principal payments received by the Administrative Agent in respect of such Unreimbursed Amount or Reimbursement Loan, plus any interest received by the Administrative Agent which have accrued on such Unreimbursed Amount or Reimbursement Loan for the period after such Lender funded such participation or Reimbursement Loan.

Mesa Credit and Guaranty Agreement —Page 44

(ii) If any payment received by the Administrative Agent pursuant to Section 2.03(d) is required to be returned under any circumstances (including pursuant to any settlement entered into by the L/C Issuer or the Support Provider, as the case may be, in its discretion), each Revolving Lender shall pay to the Administrative Agent for its own account or for the account of the L/C Issuer or Support Provider, as the case may be, its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

(f) Absolute Obligations. The obligations of each Borrower to pay its Reimbursement Obligations and its obligation to repay the Reimbursement Loans and the obligations of the Lenders to fund their portion of Reimbursement Loans or participations under Section 2.03(d) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including the following:

(i) any lack of validity or enforceability of, or any amendment or waiver of or any consent to departure from, any Letter of Credit, Support Agreement or any related document;

(ii) the existence of any claim, set-off, defense or other right which any Person may have at any time against the beneficiary of any Letter of Credit, the L/C Issuer (including any claim for improper payment), Support Provider, Administrative Agent, any Lender or any other Person, whether in connection with any Loan Document or any unrelated transaction, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(iii) any statement or any other document presented under any 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 whatsoever other than in respect of the gross negligence or willful misconduct of the L/C Issuer as determined by a non appealable decision of a court of competent jurisdiction;

(iv) any affiliation between the L/C Issuer, the Administrative Agent and/or the Support Providers; or

(v) to the extent permitted under applicable law, any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(g) Deposit Obligations of Borrowers. Upon the request of the Administrative Agent or the L/C Issuer (or the Support Provider, as the case may be), (x) if the L/C Issuer (or the Support Provider, as the case may be) has honored any full or partial drawing request under any Letter of Credit (as if any Support Provider has made a payment under a Support Agreement) and such drawing (or payment) has resulted in any Unreimbursed Amounts or (y) in the event any Letters of Credit, Support Agreements or Unreimbursed Amounts are outstanding at the time that Borrowers prepay or are required to repay the Obligations or the Revolving Commitment is terminated, Borrowers shall (i) Cash Collateralize one hundred and five percent (105%) of the

Mesa Credit and Guaranty Agreement —Page 45

aggregate outstanding Letter of Credit Liabilities and such Cash Collateral shall be available to Administrative Agent, for its benefit and the benefit of issuers of Lender Letters of Credit and Support Providers, to reimburse payments of drafts drawn under such Letters of Credit and pay any fees and expenses related thereto and (ii) prepay the fee payable under Section 2.03(e) with respect to such Letters of Credit for the full remaining terms of such Letters of Credit. At any time that there shall exist a Defaulting Lender, promptly upon the request of the Administrative Agent, the L/C Issuer (or the Support Provider, as the case may be) or the Swingline Lender, the Borrowers shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.16(d) and any Cash Collateral provided by the Defaulting Lender). Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.03 in respect of Letters of Credit shall be held and applied in satisfaction of the specific Letter of Credit Liabilities, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided herein. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender) or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Loan Party shall not be released during the continuance of a Default or an Event of Default and (y) the Person providing Cash Collateral and the L/C Issuer (or the Support Provider, as the case may be) may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations. Each Borrower hereby grants to the Administrative Agent, for the benefit of the Administrative Agent and the other Secured Parties, a security interest in all such cash, deposit accounts and all balances therein pledged, deposited with or delivered to the Administrative Agent and all proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing deposit accounts at a bank designated by the Administrative Agent.

(h) Applicability of ISP98 and UCP. Unless otherwise expressly set forth in the applicable Letter of Credit, (i) the rules of the ISP shall apply to each standby Letter of Credit and (ii) the rules of the UCP shall apply to each commercial Letter of Credit.

(i) 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 Borrowers, the Borrowers shall be obligated to pay any Unreimbursed Amount. The Borrowers hereby acknowledge that the issuance of Letters of Credit or any Support Agreement for the account of any such Subsidiary inures to the benefit of the Borrowers and that the Borrowers’ business derives substantial benefits from the businesses of such Subsidiaries.

(j) Role of L/C Issuer and Others, Conflicts. (i) The L/C Issuer, its correspondents, participants or assignees, the Administrative Agent, the Support Providers and the Agent Related Persons (collectively, the “Released Persons”) shall have no responsibility to obtain any document (other than the L/C Issuer’s obligation to obtain any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or

Mesa Credit and Guaranty Agreement —Page 46

accuracy of any such document or the authority of the Person executing or delivering any such document. No Released Person shall be liable to any Loan Party or any Lender for (A) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (B) any action taken or omitted in the absence of gross negligence or willful misconduct of such Released Person as determined by a final non appealable decision of a court of competent jurisdiction; or (C) the due execution, effectiveness, validity or enforceability of any Issuer Document or any other document or instrument related to any Letter of Credit or Support Agreement. Each Loan Party and their Subsidiaries hereby assume all risks of the acts or omissions of any beneficiary or transferee with respect to the use of any Letter of Credit. No Released Person shall be liable or responsible for any of the matters described in Section 2.03(f), provided, that anything in such clauses to the contrary notwithstanding, the Borrowers may have a claim against the L/C Issuer, and the L/C Issuer may be liable to the Borrowers, to the extent, but only to the extent, of any direct (as opposed to consequential, punitive or exemplary) damages suffered by the Borrowers which the Borrowers prove were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit, each as determined by a final non appealable decision of a court of competent jurisdiction. In furtherance and not in limitation of the foregoing, the L/C Issuer 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, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(ii) In the event of any conflict between the terms hereof and the terms of any Issuer Documents, the terms hereof shall control.

(iii) The failure of the L/C Issuer to agree to or to conform with the terms of this Agreement (particularly if the L/C Issuer is not a party to this Agreement) shall in no way limit the obligations of the Loan Parties hereunder or subject the Administrative Agent, Support Providers or any Agent-Related Person to any liability.

2.04 Swingline Loans.

(a) Swingline Facility. Subject to all of the terms and conditions of this Agreement (including the applicable conditions set forth in Article 4), the Swingline Lender may, in its sole discretion and in reliance upon the representations and warranties of the Borrowers set forth herein and the agreements of the other Lenders set forth in Sections 2.04(c) and 2.04(d) make Swingline Loans to the Borrower Representative on behalf of the Borrowers, from time to time during the Availability Period, for the purposes identified in Section 6.11, notwithstanding the fact that the aggregate amount of the outstanding Swingline Loans, when added to the Swingline Lender’s Pro Rata Share of the outstanding Revolving Loans and Letter of Credit Liabilities, from time to time may exceed the amount of such Lender’s Revolving Commitment; provided, that, after giving effect to any Borrowing of a Swingline Loan, (i) the total Revolving Exposures shall not exceed the total Revolving Commitments, (ii) the Revolving Exposure of any Lender shall not exceed such Lender’s Revolving Commitment (except that in

Mesa Credit and Guaranty Agreement —Page 47

the case of the Swingline Lender, the Swingline Lender’s Revolving Exposure (excluding all Swingline Exposure) plus the principal balance of all outstanding and the proposed Swingline Loans shall not exceed the sum of such Revolving Exposure (other than Swingline Exposure) plus the Swingline Loan Sublimit), and (iii) the total Swingline Exposure shall not exceed the Swingline Loan Sublimit. Each Swingline Loan shall be a Base Rate Loan. No Swingline Loan shall be used for the purpose of funding the payment of the principal of any other Swingline Loan. Immediately upon the making of a Swingline Loan, each Revolving Lender shall be deemed to have purchased, and hereby irrevocably and unconditionally agrees to purchase, from the Swingline Lender, a risk participation in such Swingline Loan in an amount equal to the product obtained by multiplying such Lender’s Pro Rata Share by the amount of such Swingline Loan. Swingline Loans may be prepaid and re-borrowed from time to time during the Availability Period. All Swingline Loans shall be paid in full no later than the earlier of the tenth (10th) Business Day following the Borrowing of such Swingline Loan and the Revolving Loan Maturity Date.

(b) Funding Procedures for Swingline Loans. In order to request a Swingline Loan, the Borrower Representative shall give to the Administrative Agent and Swingline Lender a Swingline Loan Notice (or telephonic notice to be confirmed promptly with a Swingline Loan Notice) of a proposed Borrowing consisting of a Swingline Loan, specifying the amount of the requested Swingline Loan, not later than 11:00 a.m. on the Business Day of the proposed Borrowing. Subject to the foregoing, on the Business Day of the proposed Borrowing, the Swingline Lender may make the proceeds of the requested Swingline Loan available to the Borrower Representative by crediting an account of the Borrower Representative that has been designated for such purpose in writing by the Borrower Representative to the Swingline Lender. Each Swingline Loan shall be in a minimum amount of $250,000 and in integral multiples of $50,000 in excess of that amount.

(c) Repayment of Swingline Loans with Revolving Loans. Regardless of whether the conditions set forth in Sections 4.01 and 4.02 have been or are capable of being satisfied and without limiting the requirement of the Borrowers to repay the Swingline Loans as set forth in the last sentence of Section 2.04(a), on any Business Day the Swingline Lender may, in its sole discretion, give notice to the Lenders that some part or all of the outstanding Swingline Loans are to be repaid on the next succeeding Business Day with a Borrowing of Revolving Loans constituting Base Rate Loans made pursuant to Section 2.01 (but not subject to the minimum borrowing requirements of Section 2.02) in the same manner and with the same force and effect as if the Borrower Representative had submitted a Loan Notice therefor pursuant to Section 2.02. Swingline Lender hereby agrees that it shall request such a settlement of all of the outstanding Swingline Loans from Revolving Lenders at least once every ten (10) Business Days. Each Lender holding a Revolving Commitment shall make the amount of its Revolving Loan available to the Administrative Agent, in immediately available funds, at Administrative Agent’s Office, not later than 11:00 a.m. on the applicable funding date. The Administrative Agent shall make the proceeds of such Revolving Loans available to the Swingline Lender on such funding date by causing an amount of immediately available funds equal to the proceeds of all such Revolving Loans received by the Administrative Agent to be credited to an account of the Swingline Lender at such office of the Administrative Agent or shall make such proceeds available to the Swingline Lender in such other manner as shall be satisfactory to the Administrative Agent and the Swingline Lender.

Mesa Credit and Guaranty Agreement —Page 48

(d) Participations in Swingline Loans. If for any reason a requested Borrowing of Revolving Loans pursuant to Section 2.04(c) is not or cannot be effected, the Revolving Lenders will, as of the date such proposed Borrowing otherwise would have occurred but adjusted for any payments received in respect of such Swingline Loan(s) by or for the account of the Borrowers on or after such date and prior to such purchase, immediately fund their respective participations in the outstanding Swingline Loans as necessary to cause such Lenders to share in such Swingline Loan(s) proportionately in accordance with their respective Pro Rata Shares. Whenever, at any time after any Revolving Lender has funded its purchase of a participating interest in a Swingline Loan, the Swingline Lender receives any payment on account thereof, the Swingline Lender will distribute to such Lender its proportionate share of such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded), provided, that in the event any such payment received by the Swingline Lender is subsequently set aside or is required to be refunded, returned or repaid, such Lender will repay to the Swingline Lender its proportionate share thereof.

(e) Failure to Pay by Lenders. If any Lender shall fail to perform its obligation to make a Revolving Loan pursuant to Section 2.04(c) or to fund its purchase of a participation in Swingline Loans pursuant to Section 2.04(d), the amount in default shall bear interest for each day from the day such amount is payable until fully paid at a rate per annum equal to (i) for the first three (3) days, the Federal Funds Rate and (ii) thereafter, the Base Rate plus the Applicable Margin in respect of Revolving Loans which are Base Rate Loans, and such obligation may be satisfied by application by the Administrative Agent (for the account of the Swingline Lender) of any payment that such Lender otherwise is entitled to receive under this Agreement. Pending repayment, each such advance shall be secured by such Lender’s participation interest, if any, in the Swingline Loans and any security therefor, and the Swingline Lender shall be subrogated to such Lender’s rights hereunder in respect thereof.

(f) Lenders’ Obligations Absolute. The obligation of each Lender to make Revolving Loans pursuant to Section 2.04(c) and to purchase participations in Swingline Loans pursuant to Section 2.04(d) shall be unconditional and irrevocable, shall not be subject to any qualification or exception whatsoever, shall be made in accordance with the terms and conditions of this Agreement under all circumstances and shall be binding in accordance with the terms and conditions of this Agreement under all circumstances, including the following circumstances: (i) any lack of validity or enforceability of this Agreement, any of the other Loan Documents or any other instrument, document or agreement relating to the transactions that are the subject thereof; (ii) the existence of any claim, defense, set-off or other right that any Borrower, any Guarantor or any Lender may have at any time against the any Agent-Related Person, the Swingline Lender, any other Lender, or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any related transactions; (iii) the surrender or impairment of any security for the performance or observance of any of the terms of this Agreement; (iv) the occurrence or continuance of any Default or failure of any condition in Article 4 to have been satisfied upon funding the Swingline Loan or thereafter; (v) any adverse

(g) change in the condition (financial or other) of any Borrower or any Guarantor; or (vi) any other reason.

Mesa Credit and Guaranty Agreement —Page 49

2.05 Prepayments.

(a) Voluntary Prepayments of Loans.

(i) Revolving Loans. Subject to the limitations set forth in this Section 2.05(a), the Borrowers may, upon notice from the Borrower Representative to the Administrative Agent, at any time or from time to time voluntarily prepay Revolving Loans in whole or in part without premium or penalty, provided that (i) such notice must be received by the Administrative Agent not later than 1:00 p.m. (A) three (3) Business Days prior to any date of prepayment of LIBOR Loans, and (B) one (1) Business Day prior to the date of prepayment of Base Rate Loans; (ii) any such prepayment of LIBOR Loans shall be in a principal amount of $250,000 or a whole multiple of $50,000 in excess thereof (or, if less, the entire principal amount thereof then outstanding) and (iii) any such prepayment of Base Rate Loans shall be in a principal amount of $250,000 or a whole multiple of $50,000 in excess thereof (or, if less, the entire principal amount thereof then outstanding). Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Pro Rata Share of such prepayment. If such notice is delivered by the Borrower Representative, the Borrowers shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein, unless such notice is made in connection with the prepayment in full of all Loans and the termination of all commitments under this Agreement, in which case no prepayment shall be required hereunder if the condition to such commitment termination is not satisfied as contemplated by Section 2.06. Any prepayment of a LIBOR Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Notwithstanding the foregoing, the Borrowers may not voluntarily prepay any Loans that are LIBOR Loans unless such Loans are prepaid at the end of the applicable Interest Period or unless the Borrowers pay all breakage costs associated with such prepayment as provided in Section 3.Q5 hereof.

(ii) Application of Voluntary Prepayments of Revolving Loans. Prepayments of Revolving Loans pursuant to this Section 2.05(a) shall not reduce the total Revolving Commitments. Each such prepayment shall be applied to the Revolving Loans of the applicable Lenders in accordance with their respective Pro Rata Shares.

(iii) Prepayment of Swingline Loans. The Borrowers may prepay Swingline Loans, in whole or in part, at any time and from time to time. The Borrowers shall, prior to or contemporaneously with making any such prepayment, give the Swingline Lender such notice of prepayment (written notice or telephonic notice confirmed in writing to the Swingline Lender) as is sufficient to enable the Swingline Lender to apply such prepayment properly to the repayment of Swingline Loans.

(b) Mandatory Prepayments of Loans.

(i) Total Revolving Exposure. If, for any reason (a) the total Revolving Exposures at any time exceed the total Revolving Commitments then in effect,

Mesa Credit and Guaranty Agreement —Page 50

(b) the aggregate Letter of Credit Liabilities exceed the Letter of Credit Sublimit, or (c) the total Swingline Exposure exceeds the Swingline Loan Sublimit, the Borrowers shall immediately prepay the Revolving Loans and/or Cash Collateralize the Letter of Credit Liabilities, or prepay the Swingline Loans, as applicable, in an aggregate amount equal to any such excess (each such prepayment to be applied as set forth in clause (v) below).

(ii) Dispositions and Involuntary Dispositions. The Borrowers shall prepay the Revolving Loans and thereafter, all other Obligations, promptly following the occurrence of any Disposition or Involuntary Disposition, in an aggregate amount equal to 100% of the Net Cash Proceeds of such Disposition of Collateral or Involuntary Disposition of Collateral (each such prepayment to be applied as set forth in clause (v) below) excluding the proceeds of any voluntary Disposition described in clause (i) of Section 7.05.

(iii) Extraordinary Receipts. Upon receipt by any Loan Party of any Extraordinary Receipts, the Borrower shall prepay the Revolving Loans and thereafter, all other Obligations in an aggregate amount equal to one hundred percent (100%) of such Extraordinary Receipts and shall be applied as set forth in clause (v) below.

(iv) Borrowing Base Deficiency. If, on any Borrowing Base Certificate Date, a Borrowing Base Deficiency exists, the applicable Loan Parties shall immediately prepay Swingline Loans and Revolving Loans and/or Cash Collateralize the Letter of Credit Liabilities, in an aggregate amount necessary to reduce such Borrowing Base Deficiency to zero (each such prepayment to be applied as set forth in clause (v) below).

(v) Application of Mandatory Prepayments. All amounts required to be paid pursuant to this Section 2.05(b) shall be applied as follows: (x) to the Swingline Loans, to the full extent thereof, (y) after all Swingline Loans have been repaid, to the Revolving Loans to the full extent thereof and, (z) after all Swingline Loans and Revolving Loans have been repaid, to Cash Collateralize any Letter of Credit Liabilities.

(c) Within the parameters of the applications set forth above, prepayments shall be applied first to Base Rate Loans and then to LIBOR Loans in direct order of Interest Period maturities. Prepayments of the Revolving Loans pursuant to this Section 2.05(c) shall not reduce the total Revolving Commitments. All prepayments under this Section 2.05(c) shall be subject to Section 3.05, but otherwise shall be without premium or penalty, and shall be accompanied by a payment of all interest accrued on the principal amount prepaid through the date of prepayment.

2.06 Termination or Reduction of Total Revolving Commitments. The Borrowers may, upon prior written notice from the Borrower Representative to the Administrative Agent, terminate the total Revolving Commitments or from time to time permanently reduce the total Revolving Commitments; provided, however that (a) any such notice shall be received by the Administrative Agent not later than 1:00 p.m. (i) ten (10) Business Days prior to the date of termination or (ii) three (3) Business Days prior to the date of reduction, (b) any such partial reduction shall be in an aggregate amount of $1,000,000 or any whole multiple of $100,000 in

Mesa Credit and Guaranty Agreement —Page 51

excess thereof, (c) after giving effect to any reduction of the total Revolving Commitments, the total Revolving Commitments shall not be less than (i) the total Revolving Exposures or (ii) the sum of the Letter of Credit Sublimit and the Swingline Loan Sublimit, (d) any termination of all Revolving Commitments shall be accompanied by a prepayment in full of all Revolving Loans and all Letter of Credit Liabilities shall be Cash Collateralized in accordance with the terms of Section 2.03(g), and (e) the Administrative Agent shall not be required to release its Lien on any Collateral in connection with any termination (other than on the Termination Date) or reduction. The Administrative Agent will promptly notify the Revolving Lenders of any such notice of termination or reduction of the Revolving Commitments. Any reduction of the total Revolving Commitments shall be applied to the Revolving Commitment of each Lender according to its Pro Rata Share. All fees accrued with respect thereto until the effective date of any termination or reduction of the total Revolving Commitments shall be paid on the effective date of such termination or reduction. Any notice of termination of the total Revolving Commitments delivered by the Borrower Representative pursuant to this Section 2.06 shall be irrevocable, provided that a notice of termination of the Revolving Commitments may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower Representative (by notice to the Administrative Agent at least one (1) Business Day prior to the specified effective date) if such condition is not satisfied.

2.07 Repayment of Loans.

(a) Revolving Loans. On the Revolving Loan Maturity Date, the Borrowers shall repay to the Administrative Agent, for the ratable benefit of the Lenders, the aggregate principal amount of all Revolving Loans outstanding on such date.

(b) Swingline Loans. The Borrowers shall repay each Swingline Loan as provided in Section 2.04(a).

2.08 Interest.

(a) Subject to the provisions of subsection (b) below, (i) each LIBOR Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the sum of (A) the LIBO Rate for such Interest Period plus (B) the Applicable Margin; and (ii) each Base Rate Loan bear interest on the outstanding principal amount thereof from the applicable borrowing or conversion date at a rate per annum equal to the (A) Base Rate plus (B) the Applicable Margin.

(b) After the occurrence and during the continuation of an Event of Default, at the election of the Administrative Agent or the Required Lenders (unless an Event of Default exists pursuant to Section 9.01(a), Section 9.01(f) or Section 9.01(g), in which event such an election shall be deemed to have automatically occurred without any further action of the Administrative Agent or the Required Lenders), the Borrowers shall pay interest on the principal amount of all outstanding Loans and any interest payments thereon not paid when due and any fees and other amounts then due and payable hereunder or under any other Loan Document at a rate per annum equal to the Default Rate to the fullest extent permitted by applicable Laws, commencing upon the occurrence of such Event of Default, notwithstanding when such election is made.

Mesa Credit and Guaranty Agreement —Page 52

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law whether or not allowed in such proceeding.

2.09 Fees.

(a) Unused Revolving Commitments Fee. The Borrowers shall pay, or cause to be paid, to the Administrative Agent for the account of each Revolving Lender in accordance with its Pro Rata Share, an unused fee equal to the product of (i) the Revolving Commitment Fee Percentage times (ii) the average daily amount by which the total Revolving Commitments exceed the sum of (y) the total outstanding amount of Revolving Loans (excluding Swingline Loans) and (z) the total Letter of Credit Liabilities. This unused fee shall accrue at all times during the Availability Period, including at any time during which one or more of the conditions in Article 4 is not met, and shall be due and payable monthly in arrears on the first day of each month, commencing with the first such date to occur after the Closing Date, and on the Revolving Loan Maturity Date; provided that no such unused fee shall accrue on the Revolving Commitment of a Defaulting Lender so long as such Lender shall be a Defaulting Lender (not including any portion thereof reallocated to non-Defaulting Lenders pursuant to Section 2.16(d) hereof).

(b) Other Fees. The Borrowers shall pay the fees in the amounts and at the times specified in the Fee Letter, and in furtherance of the foregoing, the Borrowers hereby assume the obligations of each Person (other than a Secured Party) arising under the Fee Letter. Such fees shall be fully earned when paid and shall be non-refundable for any reason whatsoever.

2.10 Computation of Interest and Fees. All computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed, except that interest computed by reference to clause (b) of the definition of Base Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid.

2.11 Evidence of Debt.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender with respect to this Agreement shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrowers and the interest and payments thereon with respect to this Agreement and the other Loan Documents. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers 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 and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the

Mesa Credit and Guaranty Agreement —Page 53

Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a promissory note, which shall evidence such Lender’s Loans in addition to such accounts or records. Each such promissory note shall (i) in the case of Revolving Loans, be substantially in the form of Exhibit B-1 (a “Revolving Note”), and (ii) in the case of Swingline Loans, be substantially in the form of Exhibit B-2 (the “Swingline Note”). Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto, but any failure to do so shall not limit or otherwise affect the Borrowers’ Obligations hereunder.

(b) In addition to the accounts and records referred to in subsection (a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.12 Payments Generally.

(a) All payments to be made by the Borrowers of principal, interest, fees and other Obligations shall be absolute and unconditional and shall be made without condition or deduction for any counterclaim, defense, recoupment, setoff or rescission. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office (or, in the case of Swingline Loans and if so directed in writing by Swingline Lender, delivered directly to the Swingline Lender) in Dollars and in immediately available funds not later than 12:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Pro Rata Share (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 12:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

(b) Subject to the definition of “Interest Period”, if any payment to be made by the Borrowers shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(c) Unless any Borrower or any Lender has notified the Administrative Agent, prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that any Borrower or such Lender, as the case may be, will not make such payment, the Administrative Agent may assume that the Borrowers or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then:

Mesa Credit and Guaranty Agreement —Page 54

(i) if any Borrower failed to make such payment, each Lender shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds at the Federal Funds Rate from time to time in effect; and

(ii) if any Lender failed to make such payment, such Lender shall forthwith on demand pay to the Administrative Agent the amount thereof, in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Administrative Agent to the Borrowers to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to (i) for the first three (3) days, the Federal Funds Rate and (ii) thereafter, the Base Rate plus the Applicable Margin in respect of Revolving Loans which are Base Rate Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in the applicable Borrowing. If such Lender does not pay such amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent may make a demand therefor upon the Borrowers, and the Borrowers shall pay such amount to the Administrative Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Revolving Commitment or to prejudice any rights which the Administrative Agent or the Borrowers may have against any Lender as a result of any default by such Lender hereunder.

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

(d) The obligations of the Lenders hereunder to make Loans are several and not joint. The failure of any Lender to make any Loan or to fund any participation on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or purchase its participation.

2.13 Sharing of Payments. If, other than as provided elsewhere in this Agreement, in the Fee Letter, in any Assignment and Assumption permitted hereunder or in any participation agreement with a Participant permitted hereunder, any Lender shall obtain on account of the Loans made by it, or Letter of Credit Liabilities or Swingline Exposures held by it, any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its Pro Rata Share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them, and/or such subparticipations in Letter of Credit Liabilities and Swingline Exposures held by them, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loans or such participations, as the case may be, pro rata with each of them, provided, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the circumstances

Mesa Credit and Guaranty Agreement —Page 55

described in Section 12.06 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon. The Borrowers agree that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by Law, exercise all its rights of payment (including the right of set-off, but subject to Section 12.09) with respect to such participation as fully as if such Lender were the direct creditor of the Borrowers in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section 2.13 and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

2.14 Handling of Proceeds of Collateral; Cash Dominion; Revolving Loan Account; Cash Management Procedures.

(a) Collection of Accounts and Other Proceeds. The Borrowers, at their expense, will enforce and collect payments and other amounts owing on all Accounts in the ordinary course of the Borrowers’ business subject to the terms hereof. The Borrowers shall deposit and agree to direct all of their account debtors to deposit payments on all Accounts directly to one or more Controlled Accounts. Notwithstanding the foregoing, should any Borrower ever receive any payment on an Account or other proceeds of the sale of Collateral, including checks, cash, receipts from credit card sales and receipts, notes or other instruments or property with respect to any Collateral, such Borrower agrees to hold such proceeds separate from such Borrower’s other property and funds, and to deposit such proceeds directly into the bank account(s) maintained pursuant to this subsection within three (3) Business Days.

(b) Transfer of Funds. During a Cash Control Period, the Administrative Agent shall have the right, at the Administrative Agent’s election in its sole discretion, to require that funds remaining on deposit in any Controlled Account be transferred to the Administrative Agent’s Bank Account on each Business Day, and the Borrowers shall take all actions required by the Administrative Agent or by any bank at which any Controlled Account is maintained in order to effectuate the transfer of funds in this manner. All amounts so received will, for purposes of calculating Revolving Availability and interest, be credited to the Revolving Loan Account on the date of deposit in the Administrative Agent’s Bank Account. No checks, drafts or other instruments received by the Administrative Agent shall constitute final payment to the Administrative Agent unless and until such instruments have actually been collected.

(c) New Bank Accounts. Each Borrower agrees not to open any new bank account into which proceeds of Collateral are to be delivered or deposited unless such bank account is established at CIT (unless such account constitutes an Excluded Account). Any such

Mesa Credit and Guaranty Agreement —Page 56

bank account shall constitute a Controlled Account for purposes of this Agreement. Notwithstanding anything to the contrary in this Section 2.14, the Borrowers may maintain one or more accounts constituting Excluded Accounts, provided that if such account ceases to be an Excluded Account, (i) Borrowers shall cause such account to be a Controlled Account within thirty (30) days of such event and (ii) pending such account becoming a Controlled Account, Borrowers shall cause the daily transfer of funds in such account into another Controlled Account.

(d) Collective Borrowing Arrangement. The Borrowers have informed the Administrative Agent that: (i) in order to increase the efficiency, profitability and productivity of each Borrower, the Borrower Representative has established a centralized cash management system for the Borrowers that entails, in part, central disbursement and operating accounts for each of the Borrowers in which the Borrower Representative provides the working capital needs of each of the other Borrowers and manages and timely pays the accounts payable of each of the other Borrowers; (ii) the Borrower Representative further enhances the operating efficiencies of the other Borrowers by purchasing, or causing to be purchased, in the Borrower Representative’s name for its account, all or substantially all materials, supplies, inventory and services required by the other Borrowers, resulting in a reduction in operating costs of the other Borrowers; and (iii) all of the Borrowers presently engage in an integrated operation that requires financing on an integrated basis, and each Borrower expects to benefit from the continued successful performance of such integrated operations. Therefore, in order to best utilize the borrowing powers of the Borrowers in the most effective and cost efficient manner and to avoid adverse effects on the operating efficiencies of each Borrower and the existing back office practices of the Borrowers, each Borrower has requested that all Revolving Loans, the Swingline Loans be disbursed, and Letters of Credit be issued, solely upon the request of the Borrower Representative and to bank accounts managed solely by the Borrower Representative, it being the intent and desire of the Borrowers that the Borrower Representative manage for the benefit of each Borrower the expenditure and usage of such funds.

(e) Revolving Loan Account. The Administrative Agent may charge the Revolving Loan Account for all loans and advances made by the Administrative Agent and the Lenders to the Borrower Representative, or otherwise for the Revolving Loan Account, and for any other Obligations, including out-of-pocket expenses of the Administrative Agent, when due and payable hereunder. Interest on the Revolving Loans shall be paid as set forth in Section 2.08 hereto. In no event shall prior recourse to any Account or other security granted to or by the Borrowers be a prerequisite to the Administrative Agent’s or the Lenders’ rights to demand payment of any of the Obligations. In addition, neither the Administrative Agent nor any Lender shall have any obligation whatsoever to perform in any respect any Borrower’s contracts or obligations relating to the Accounts.

(f) Cash Management Procedures. Each Borrower agrees to cause CIT to be its principal depositary and treasury services financial institution, including for the maintenance of operating, administrative, treasury services, cash management, collection activity and other deposit accounts for the conduct of its business.

Mesa Credit and Guaranty Agreement —Page 57

2.15 Uncommitted Facilities Increase.

(a) At any time prior to the second anniversary of the Closing Date, subject to the terms and conditions set forth herein and subject to the consent of each Lender, the Borrower Representative may, by notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders), request to add one or more increases in the Revolving Commitments (a “Revolving Commitment Increase” or the “Incremental Revolving Commitments”; individually an “Incremental Facility” and collectively the “Incremental Facilities”); provided that at the time of each such request and upon the effectiveness of each Incremental Facility Amendment (as defined below), no Default, Event of Default or Borrowing Base Deficiency has occurred and is continuing or shall result therefrom. Borrower Representative may seek commitments for the Incremental Facilities from the existing Lenders, or if the Administrative Agent consents, Additional Lenders who will become Lenders in connection therewith (and meet the requirements of an Eligible Assignee), and for the avoidance of doubt, no Secured Party shall have any obligation to provide or arrange any Additional Incremental Facility or commitment related thereto.

(b) Notwithstanding anything to contrary herein, the aggregate principal amount of all Incremental Facilities (including commitments therefor) shall not exceed $15,000,000 and not more than two (2) Incremental Facilities may be requested hereunder. Each Incremental Facility shall be in an integral multiple of $1,000,000 and be in an aggregate principal amount that is not less than $5,000,000; provided that such amount may be less than the applicable minimum amount if such amount represents all the remaining availability hereunder as set forth above.

(c) The terms, provisions and documentation of the Incremental Revolving Commitments shall be on the same terms and conditions of this Agreement, except as agreed (unless otherwise set forth in this Section 2.15) among the Borrowers, each Lender and the applicable Additional Lender(s) providing such Incremental Revolving Commitments and except that:

(i) if the Applicable Margin (which, for such purposes only, shall be deemed to include all upfront or similar fees or original issue discount (with original issue discount being equated to interest based on an assumed four-year life to maturity or, if shorter, the actual Weighted Average Life to Maturity) payable to all Additional Lenders providing such Incremental Facility (but excluding the portion of structuring, arrangement, commitment or similar fees not shared with all such Additional Lenders in connection therewith)) relating to any Incremental Facility exceeds the then Applicable Margin (which, for such purposes only, shall be deemed to include all upfront or similar fees or original issue discount (with original issue discount being equated to interest based on an assumed four-year life to maturity or, if shorter, the actual Weighted Average Life to Maturity) payable to all Lenders providing the Revolving Commitments extended on the Closing Date (the “Closing Date Facilities”) immediately prior to the effectiveness of the applicable Incremental Facility Amendment by more than 0.50%, the Applicable Margin relating to the Closing Date Facilities shall be adjusted to be equal to the Applicable Margin (which, for such purposes only, shall be deemed to include all upfront or similar fees or original issue discount (with original issue discount being

Mesa Credit and Guaranty Agreement —Page 58

equated to interest based on an assumed four-year life to maturity or, if shorter, the actual Weighted Average Life to Maturity) payable to all Additional Lenders providing such Incremental Facilities (but excluding structuring, arrangement, commitment or similar fees not shared with all such Additional Lenders in connection therewith)) relating to such Incremental Facilities minus 0.50%,

(ii) and any Incremental Revolving Commitments will be subject to the same pro rata borrowing, Letter of Credit participations and prepayment and commitment reduction provisions as the existing Revolving Commitments,

(iii) such Incremental Facilities (a) shall not be secured by any Lien on any asset of any Person that does not also secure the then outstanding Closing Date Facilities or (b) shall not be guaranteed by any Person other than a Loan Party under the then outstanding Closing Date Facilities.

(d) Each notice from the Borrowers pursuant to this Section 2.15(d) shall set forth the requested amount and proposed terms of the relevant Incremental Revolving Commitments, as applicable. If the Administrative Agent does not receive within a time period proscribed by the Administrative Agent sufficient commitments from existing Lenders to effectuate the Incremental Revolving Commitments, as applicable, any additional bank, financial institution, existing Lender or other Person that constitutes an entity of the type that would be an Eligible Assignee electing to extend Incremental Revolving Commitments shall be determined by the Borrower (subject to the consent of (y) the Administrative Agent and (z) the L/C Issuer (or if applicable, the Support Provider) and the Swingline Lender solely with respect to Incremental Revolving Commitments) (any such bank, financial institution, existing Lender or other Person being called an “Additional Lender”) and, if not already a Lender, shall become a Lender under this Agreement pursuant to an amendment (an “Incremental Facility Amendment”) to this Agreement and, as appropriate, the other Loan Documents, executed by (in form and substance mutually acceptable to each of) the Loan Parties, each Lender, such Additional Lender, the Administrative Agent, and in the case of any Incremental Revolving Commitments, each L/C Issuer (or if applicable, the Support Provider) and Swingline Lender, and shall join as a Lender (and in any event, shall be bound by and subject to) the AAR Cooperation Agreement. For the avoidance of doubt, no L/C Issuer (or if applicable, Support Provider) and Swingline Lender is required to act as such for any Additional Revolving Commitments unless they so consent. No Incremental Facility Amendment shall require the consent of any Lenders other than the Additional Lenders with respect to such Incremental Facility Amendment. Ultimate allocation of any Incremental Revolving Commitments to Lenders and/or Additional Lenders shall be made at the sole discretion of the Administrative Agent.

Upon each increase in the Revolving Credit Commitments pursuant to this Section 2.15, each Revolving Lender immediately prior to such increase will automatically and without further action be deemed to have assigned to each Lender providing a portion of the Incremental Revolving Commitment (each an “Incremental Revolving Lender”) in respect of such increase, and each such Incremental Revolving Lender will automatically and without further act be deemed to have assumed, a portion of such Revolving Lender’s participations hereunder in outstanding Letters of Credit and Swingline Loans such that, after giving effect to each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding

Mesa Credit and Guaranty Agreement —Page 59

(i) participations hereunder in Letters of Credit and (ii) participations hereunder in Swingline Loans held by each Revolving Lender (including each such Incremental Revolving Lender) will equal the percentage of the aggregate Revolving Commitments of all Revolving Lenders represented by such Revolving Lender’s Revolving Commitment. The Administrative Agent and the Lenders hereby agree that the minimum borrowings, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. Commitments in respect of any Incremental Revolving Commitments shall become Commitments under this Agreement. Subject to Section 2.15, the effectiveness of any Incremental Facility Amendment shall, unless otherwise agreed to by the Administrative Agent, each Lender and the Additional Lenders, be subject to the satisfaction on the date thereof (each, an “Incremental Facility Closing Date”) of each of the conditions set forth in Article 4 (it being understood that (x) all references to “the date of such Credit Extension” in Article 4 shall be deemed to refer to the Incremental Facility Closing Date and (y) the Incremental Facility Closing Date shall be deemed to be the initial Credit Extension).

2.16 Defaulting Lenders. If any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) such Defaulting Lender’s Revolving Commitment and outstanding Revolving Loans shall be excluded for purposes of calculating the fee payable to Revolving Lenders in respect of Section 2.09(a), and such Defaulting Lender shall not be entitled to receive any fee pursuant to Section 2.09(a) with respect to such Defaulting Lender’s Revolving Commitment or Revolving Loans (in each case not including any fee in connection with any portion of such Defaulting Lenders Revolving Commitment that has been reallocated to non-Defaulting Lenders pursuant to Section 2.16(d) hereof).

(b) the Revolving Commitments and Loans of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.01).

(c) in the event a Defaulting Lender has defaulted on its obligation to fund any Revolving Loan, or purchase any participation pursuant to Section 2.03(d) or Section 2.04(d) hereof, until such time as the Default Excess with respect to such Defaulting Lender has been reduced to zero, any prepayments or repayments on account of the Revolving Loans or participations purchased pursuant to Section 2.03(d) or Section 2.04(d), in each case to the extent they would be otherwise be payable to such Defaulting Lender, shall be applied 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 L/C Issuer, Support Provider or Swingline Lender hereunder; third, to Cash Collateralize the L/C Issuer’s (or the Support Provider’s, as the case may be) Fronting Exposure with respect to such Defaulting Lender; fourth, as the Borrowers may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrowers, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this

Mesa Credit and Guaranty Agreement —Page 60

Agreement and (y) Cash Collateralize the L/C Issuer’s (or the Support Provider’s, as the case may be) future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the L/C Issuer, the Support Provider or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the L/C Issuer, the Support Provider or Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrowers as a result of any judgment of a court of competent jurisdiction obtained by the Borrowers against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided, that, if (x) such payment is a payment of the principal amount of any Loans or Letter of Credit Liabilities in respect of which such Defaulting Lender has not fully funded its appropriate share and (y) such Loans or Letter of Credit Liabilities were made at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to the pay the Loans of, and Letter of Credit Liabilities owed to, all non-Defaulting Lenders on a mg rata basis prior to being applied to the payment of any Loans of, or Letter of Credit Liabilities owed to, such Defaulting Lender. 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(c) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(d) If any Swingline Loans or Letter of Credit Liabilities are outstanding at the time a Lender becomes a Defaulting Lender then:

(i) so long as no Default or Event of Default then exists, all or any part of such Swingline Loans and Letter of Credit Liabilities shall be reallocated among the non-Defaulting Revolving Lenders in accordance with their respective Pro Rata Shares of the total Revolving Commitments (calculated without regard to such Defaulting Lender’s Revolving Commitments), provided that no Revolving Lender’s Revolving Exposure shall exceed its Revolving Commitment;

(ii) if the reallocation described in paragraph (i) above cannot, or can only partially, be effected, the Borrowers shall within one Business Day following notice by the Administrative Agent (A) first, prepay the amount of the Swingline Loans equal to Defaulting Lender’s Pro Rata Share thereof after giving effect to any partial reallocation pursuant to paragraph (i) above and (B) second, Cash Collateralize such Defaulting Lender’s Pro Rata Share of Letter of Credit Liabilities (after giving effect to any partial reallocation pursuant to paragraph (i) above) in accordance with the procedures set forth in Section 2.03(g) and for so long as any such Letter of Credit Obligations are outstanding;

(iii) if the Borrowers Cash Collateralize any portion of such Defaulting Lender’s Pro Rata Share of Letter of Credit Obligations pursuant to this Section 2.16(d), the Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.03(c) with respect to the portion of such Defaulting Lender’s Pro Rata Share of

Mesa Credit and Guaranty Agreement —Page 61

Letter of Credit Obligations which have been Cash Collateralized (and the Defaulting Lender shall not be entitled to receive any such fees);

(iv) if the Defaulting Lender’s Pro Rata Share of Letter of Credit Obligations are reallocated pursuant to this Section 2.16(d), then the letter of credit fees payable to the non-Defaulting Lenders pursuant to Section 2.03(c) shall be adjusted accordingly; and

(v) if any Defaulting Lender’s Pro Rata Share of Letter of Credit Liabilities is not Cash Collateralized or reallocated pursuant to this Section 2.16(d), then without prejudice to any rights or remedies of the applicable Support Provider or L/C Issuer hereunder, all letter of credit fees payable under Section 2.03(c) with respect to such Defaulting Lender’s Pro Rata Share of Letter of Credit Liabilities shall be payable to the L/C Issuer or if applicable, the Support Provider.

(e) So long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan, and no L/C Issuer or Support Provider shall be required to issue, extend or increase any Letter of Credit or Support Agreement, in each case unless it is reasonably satisfied that the related exposure will be 100% covered by the Revolving Commitments of the non-Defaulting Lenders and/or Cash Collateral will be provided by the Borrowers in accordance with Section 2.03(g), and participating interests in any such newly issued, extended or increased Letter of Credit or Support Agreement or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.16(d)(i) (and Defaulting Lenders shall not participate therein).

(f) No reallocation permitted pursuant to Section 2.16(d) 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.

(g) In the event that the Administrative Agent, the L/C Issuer, the Support Provider and the Swingline Lender each agrees in writing that a Defaulting Lender has adequately remedied all matters which caused such Lender to become a Defaulting Lender, then the Pro Rata Shares of Swingline Loans and Letter of Credit Obligations of the Revolving Lenders shall be readjusted to reflect the inclusion of such Lender’s Revolving Commitment and on such date such Lender shall purchase at par such of the Revolving Loans of the other Lenders (other than Swingline Loans) or participations in the Revolving Loans as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Revolving Loans or participations in accordance with its Pro Rata Share; provided, that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender

(h) to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender having been a Defaulting Lender.

Mesa Credit and Guaranty Agreement —Page 62

(i) The rights and remedies with respect to a Defaulting Lender under this Section 2.16 are in addition to any other rights and remedies which the Borrower, the Administrative Agent, the L/C Issuer, the Support Provider or the Swingline Lender, as applicable, may have against such Defaulting Lender.

ARTICLE 3

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

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

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

(c) Indemnification by the Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower Representative 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.

(d) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.07(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable

Mesa Credit and Guaranty Agreement —Page 63

expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d).

(e) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 3.01, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(f) 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 Loan Document shall deliver to the Borrower Representative and the Administrative Agent, at the time or times reasonably requested by the Borrower Representative or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower Representative 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 Representative or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower Representative or the Administrative Agent as will enable the Borrower Representative 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 3.01(f)(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 Representative 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 Representative or the Administrative Agent), executed copies 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 Representative 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

Mesa Credit and Guaranty Agreement —Page 64

Representative or the Administrative Agent), whichever of the following is applicable:

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

(2) executed copies of IRS Form W-8ECI;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal Revenue Code, (x) a certificate substantially in the form of Exhibit 0-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder” of a Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable; or

(4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-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 G-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 Representative 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 Representative or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit

Mesa Credit and Guaranty Agreement —Page 65

the Borrower Representative or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Borrower Representative and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower Representative or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower Representative or the Administrative Agent as may be necessary for the Borrower Representative 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 Representative and the Administrative Agent in writing of its legal inability to do so.

(g) 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 3.01 (including by the payment of additional amounts pursuant to this Section 3.01), 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 (g) (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 (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (g) 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 Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax 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.

Mesa Credit and Guaranty Agreement —Page 66

(h) Survival. Each party’s obligations under this Section 3.01 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund LIBOR Loans, or to determine or charge interest rates based upon the LIBO Rate, 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 London interbank market, then, on notice thereof by such Lender to the Borrowers through the Administrative Agent, any obligation of such Lender to make or continue LIBOR Loans or to convert Base Rate Loans to LIBOR Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrowers that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrowers shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all LIBOR Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such LIBOR Loans. Upon any such prepayment or conversion, the Borrowers shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to use reasonable efforts consistent with legal and regulatory requirements to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be disadvantageous to such Lender or cost any additional amount.

3.03 Inability to Determine Rate. If the Administrative Agent determines that for any reason adequate and reasonable means do not exist for determining the LIBO Base Rate for any requested Interest Period with respect to a proposed LIBOR Loan, or that the LIBO Base Rate for any requested Interest Period with respect to a proposed LIBOR Loan does not adequately and fairly reflect the cost to the Lenders of funding such Loan, the Administrative Agent will promptly notify the Borrowers and all Lenders. Thereafter, the obligation of the Lenders to make or maintain LIBOR Loans shall be suspended until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrowers may revoke any pending request for a Borrowing of, conversion to or continuation of LIBOR Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

3.04 Increased Cost and Reduced Return; Capital Adequacy. (a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge, liquidity requirement or other 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 reflected in the LIBO Rate) or the L/C Issuer or Support Provider;

Mesa Credit and Guaranty Agreement —Page 67

(ii) subject any Lender or the L/C Issuer or Support Provider to any Tax of any kind whatsoever with respect to this Agreement, any Letter of Credit or Support Agreement, any participation in a Letter of Credit or any Loan made by it (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes); or

(iii) impose on any Lender, the Support Provider or the L/C Issuer or the London interbank market any other condition, cost or expense affecting this Agreement or Loans made by such Lender or any Letter of Credit or Support Agreement, or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the Support Provider or L/C Issuer of participating in, issuing or maintaining any Lender Letter of Credit or continuing its obligation under any Support Agreement (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 or the L/C Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Support Provider, or the L/C Issuer, the Borrowers will pay to such Lender, Support Provider, or L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender, Support Provider or the L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered.

(b) Without duplication of amounts payable in paragraph (a) above, if any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or 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 capital or on the capital of such Lender’s holding company, if any, as a consequence of its obligations hereunder or under or in respect of any Letter of Credit or Support Agreement, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital or liquidity adequacy), then from time to time the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

3.05 Funding Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrowers shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b) any failure by the Borrowers (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrowers; or

Mesa Credit and Guaranty Agreement —Page 68

(c) any assignment of a LIBOR Loan on a day other than the last day of the Interest Period therefor as a result of (i) a request by the Borrowers pursuant to Section 12.15, (ii) an assignment by any Lender that is a Lender on the Closing Date pursuant to Section 12.07(b) as part of the primary syndication of the Commitments and Loans following the Closing Date or (iii) an assignment by any Lender in connection with an Incremental Facility pursuant to Section 2.15;

including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. Lenders shall provide Borrower Representative with a notice (with a copy to the Administrative Agent) setting forth in reasonable detail the basis for Lenders demand, which shall be conclusive absent manifest error. Borrowers shall pay such amount within ten days after receipt of such notice.

For purposes of calculating amounts payable by the Borrowers to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each LIBOR Loan made by it at the LIBO Base Rate used in determining the LIBO Rate for such Loan by a matching deposit or other borrowing in the London interbank market for a comparable amount and for a comparable period, whether or not such LIBOR Loan was in fact so funded.

3.06 Matters Applicable to all Requests for Compensation.

(a) A certificate of the Administrative Agent or any Lender, Support Provider, or L/C Issuer claiming compensation under this Article 3 and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Administrative Agent or such Lender, Support Provider or L/C Issuer may use any reasonable averaging and attribution methods. The Borrowers shall pay the Administrative agent, Lender, Support Provider or L/C Issuer the amount shown as due on any such certificate within ten (10) days of receipt thereof.

(b) Upon any Lender’s making a claim for compensation under Section 3.01 or 3.04, the Borrowers may replace such Lender in accordance with Section 12.15.

3.07 Survival. All of the Borrowers’ obligations under this Article 3 shall survive the Termination Date.

ARTICLE 10

GUARANTY

10.01 The Guaranty. Each Guarantor hereby guarantees to each Secured Party and the Administrative Agent as hereinafter provided, as primary obligor and not as surety, the prompt payment and performance of the Obligations in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration or otherwise) strictly in accordance with the terms thereof. Each Guarantor hereby further agrees that if any of the Obligations are not paid in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration or otherwise), each Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Obligations, the same will be promptly paid in full when due (whether at extended maturity, as a mandatory prepayment, by acceleration or otherwise) in accordance with the terms of such extension or renewal (collectively, the “Guaranteed Obligations”).

Subject to Section 10.06 and the last sentence of this Section 10.01 below, the Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which the Administrative Agent or any Secured Party may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of any Guaranteed Obligations to be paid when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), the Guarantors will, upon demand pay, or cause to be paid, in cash, to the Administrative Agent for the ratable benefit of Secured Parties, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for any Borrower’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against any Borrower for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Secured Parties as aforesaid.

Notwithstanding any provision to the contrary contained herein or in any other of the Loan Documents, the Guaranteed Obligations of each Guarantor under this Agreement and the other Loan Documents shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under the Debtor Relief Laws.

10.02 Obligations Unconditional. The Guaranteed Obligations of each Guarantor under Section 10.01 are joint and several and absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of any of the Loan Documents or any

Mesa Credit and Guaranty Agreement —Page 101

other agreement or instrument referred to therein, or any substitution, release, impairment or exchange of any other guarantee of or security for any of the Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 10.02 that the obligations of each Guarantor hereunder shall be absolute and unconditional under any and all circumstances. Each Guarantor agrees that such Guarantor shall have no right of subrogation, indemnity, reimbursement or contribution against the Borrowers or any other Guarantor for amounts paid under this Article 10 until the Termination Date. Without limiting the generality of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the liability of any Guarantor hereunder, which shall remain joint and several and absolute and unconditional as described above:

(a) at any time or from time to time, without notice to any Guarantor, the time for any performance of or compliance with any of the Obligations shall be extended, or such performance or compliance shall be waived;

(b) any of the acts mentioned in any of the provisions of any of the Loan Documents or any other agreement or instrument referred to in the Loan Documents shall be done or omitted;

(c) the maturity of any of the Obligations shall be accelerated, or any of the Obligations shall be modified, supplemented or amended in any respect, or any right under any of the Loan Documents or any other agreement or instrument referred to in the Loan Documents shall be waived or any other guarantee of any of the Obligations or any security therefor shall be released, impaired or exchanged in whole or in part or otherwise dealt with;

(d) any Lien granted to, or in favor of, the Administrative Agent or any Secured Party or Secured Parties as security for any of the Obligations shall fail to attach or be perfected;

(e) any of the Obligations shall be determined to be void or voidable (including for the benefit of any creditor of any Guarantor) or shall be subordinated to the claims of any Person (including any creditor of any Guarantor); or

(f) any other action or inaction shall occur that might constitute a surety defense.

10.03 Reinstatement. The Guaranteed Obligations of any Guarantor under this Article 10 shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and each Guarantor agrees that it will indemnify the Administrative Agent and each Secured Party on demand for all reasonable costs and expenses (including fees and expenses of counsel) incurred by the Administrative Agent or such Secured Party in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference,

Mesa Credit and Guaranty Agreement —Page 102

fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law. This paragraph shall survive any termination of this Agreement.

10.04 Waivers.

(a) Each Guarantor hereby waives, to the fullest extent permitted by Law, for the benefit of the Administrative Agent and each Secured Party: (a) any right to require the Administrative Agent or any Secured Party, as a condition of payment or performance by such Guarantor, to (i) proceed against any Borrower, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from any Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of the Administrative Agent and Secured Parties in favor of any Borrower or any other Person, or (iv) pursue any other remedy in the power of the Administrative Agent and the Secured Parties whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of any Borrower or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of any Borrower or any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal or any law, rule, regulation, or order of any jurisdiction affecting any term of the Guaranteed Obligations; (d) any defense based upon the Administrative Agent’s or any Secured Party’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that the Administrative Agent and the Secured Parties protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default under any Loan Document or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to any Borrower and notices of any of the matters referred to in Section 10.02 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof. Each Guarantor agrees that such Guarantor shall have no right of recourse to security for the Obligations, except through the exercise of rights of subrogation to the extent permitted by Section 10.02; provided, however, Guarantor agrees that such rights shall be automatically (and without any further action) irrevocably waived and released if such security is acquired by a Person as a result of the exercise of the remedies under the Loan Documents.

10.05 Remedies. Each Guarantor agrees that, to the fullest extent permitted by law, as between such Guarantor, on the one hand, and the Administrative Agent and the Secured Parties, on the other hand, the Obligations may be declared to be forthwith due and payable as provided in

Mesa Credit and Guaranty Agreement —Page 103

Section 9.02 (and shall be deemed to have become automatically due and payable in the circumstances provided in Section 9.02) for purposes of Section 10.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Obligations being deemed to have become automatically due and payable), the Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by each Guarantor for purposes of Section 10.01. Each Guarantor acknowledges and agrees that its Guaranteed Obligations hereunder are secured in accordance with the terms of the Collateral Documents and that the Secured Parties may exercise their remedies thereunder in accordance with the terms thereof.

10.06 Contribution by Guarantors. All Guarantors desire to allocate among themselves (collectively, the “Contributing Guarantors”), in a fair and equitable manner, their respective obligations arising under this Guaranty. Accordingly, in the event any payment or distribution is made on any date by a Guarantor (a “Funding Guarantor”) under this Guaranty such that its Aggregate Payments exceeds its Fair Share as of such date, such Funding Guarantor shall be entitled to a contribution from each of the other Contributing Guarantors in an amount sufficient to cause each Contributing Guarantor’s Aggregate Payments to equal its Fair Share as of such date. “Fair Share” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (a) the ratio of (i) the Fair Share Contribution Amount with respect to such Contributing Guarantor to (ii) the aggregate of the Fair Share Contribution Amounts with respect to all Contributing Guarantors multiplied by (b) the aggregate amount paid or distributed on or before such date by all Funding Guarantors under this Guaranty in respect of the obligations Guaranteed. “Fair Share Contribution Amount” means, with respect to a Contributing Guarantor as of any date of determination, the maximum aggregate amount of the obligations of such Contributing Guarantor under this Guaranty that would not render its obligations hereunder or thereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code or any comparable applicable provisions of state law, provided, solely for purposes of calculating the “Fair Share Contribution Amount” with respect to any Contributing Guarantor for purposes of this Section 10.06, any assets or liabilities of such Contributing Guarantor arising by virtue of any rights to subrogation, reimbursement or indemnification or any rights to or obligations of contribution hereunder shall not be considered as assets or liabilities of such Contributing Guarantor. “Aggregate Payments” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (1) the aggregate amount of all payments and distributions made on or before such date by such Contributing Guarantor in respect of this Guaranty (including in respect of this Section 10.06), minus (2) the aggregate amount of all payments received on or before such date by such Contributing Guarantor from the other Contributing Guarantors as contributions under this Section 10.06. The amounts payable as contributions hereunder shall be determined as of the date on which the related payment or distribution is made by the applicable Funding Guarantor. The allocation among Contributing Guarantors of their obligations as set forth in this Section 10.06 shall not be construed in any way to limit the liability of any Contributing Guarantor hereunder. Each Guarantor is a third party beneficiary to the contribution agreement set forth in this Section 10.06 and a right to receive any Fair Share Contribution Amount shall be deemed an asset of the Guarantor entitled to such amount.

Mesa Credit and Guaranty Agreement —Page 104

10.07 Guarantee of Payment; Continuing Guarantee. The guarantee in this Article 10 is an absolute and unconditional guaranty of payment and not of collection, is a continuing and irrevocable guarantee, and shall apply to all Obligations whenever arising.

10.08 Subordination of Other Obligations. Any Indebtedness of any Borrower or any Guarantor or any Subsidiary now or hereafter owing to any Loan Party (the “Obligee”) is hereby subordinated in right of payment to the Obligations (and any Lien now or hereafter securing such Indebtedness is hereby subordinated in priority to the Liens of Administrative Agent now or hereafter securing any of the Obligations), and any such Indebtedness collected or received by the Obligee after an Event of Default has occurred and is continuing shall be held in trust for the Administrative Agent for its benefit and the benefit of the Secured Parties and shall forthwith be paid over to Administrative Agent for its benefit and the benefit of the Secured Parties to be credited and applied against the Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee under any other provision hereof. No Obligee shall exercise any remedy with respect to such Indebtedness prior to the Termination Date.

ARTICLE 11

THE ADMINISTRATIVE AGENT

11.01 Appointment and Authorization of Administrative Agent. (a) Each Secured Party hereby irrevocably appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Secured Party or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents 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 merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) Each L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and each Support Provider shall act on behalf of the Lenders with respect to any Support Agreements entered into by it and the documents associated therewith and each L/C Issuer and Support Provider, respectively, shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article 11 with respect to any acts taken or omissions suffered by such L/C Issuer or Support Provider in connection with Letters of Credit and Support Agreements issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit and Support Agreements as fully as if the term “Administrative Agent” as used in this Article 11 and in the definition of “Agent-Related Person” included such L/C Issuer or Support Provider

Mesa Credit and Guaranty Agreement —Page 105

with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the L/C Issuers or Support Providers.

(c) Swingline Lender shall act on behalf of the Lenders with respect to any Swingline Loan made by it and the documents associated therewith, and the Swingline Lender shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article 11 with respect to any acts taken or omissions suffered by the Swingline Lender in connection with the Swingline Loans made by it or proposed to be made by it as fully as if the term “Administrative Agent” as used in this Article 11 and in the definition of “Agent-Related Person” included the Swingline Lender with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the Swingline Lender.

11.02 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through its, or its Affiliates, agents, employees or attorneys-in-fact and shall be entitled to obtain and rely upon the advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of the Administrative Agent’s gross negligence or willful misconduct (as finally determined in a non-appealable decision of a court of competent jurisdiction).

11.03 Liability of Administrative Agent. No Agent-Related Person shall be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby, and each Loan Party and Secured Party hereby waives and agrees not to assert any right, claim or cause of action based thereon, except to the extent of liabilities resulting from its own gross negligence or willful misconduct in connection with its duties expressly set forth herein, as fmally determined in a non-appealable decision of a court of competent jurisdiction. Without limiting the foregoing, no Agent-Related Person shall be: (i) responsible or have any obligation to any other Secured Party for the due execution, validity, genuineness, effectiveness, sufficiency, or enforceability of, or for any recital, statement, warranty or representation in, this Agreement, any other Loan Document or any related agreement, document or order; (ii) required or have any obligation to ascertain, monitor or enforce or to make any inquiry concerning the performance or observance by any Loan Party and any Lender of any of the terms, conditions, covenants, or agreements of this Agreement or any of the other Loan Documents; (iii) responsible for or have any duty to ascertain or monitor or to inquire into whether a condition set forth in any Loan Document is satisfied, or waived, including any condition set forth in Article 4 hereof; (iv) responsible or have any obligation to any other Secured Party for the state or condition of any properties of the Loan Parties constituting Collateral for the Obligations or any information contained in the books or records of the Loan Parties; (v) responsible or have any obligation to any other Secured Party for the validity, enforceability, collectability, effectiveness or genuineness of this Agreement or any other Loan Document or any other certificate, document or instrument furnished in connection therewith; (vi) liable with respect to or arising out of any assignment or participation of the Obligations, or disclosure of any information, to any Secured Party or such Secured Party’s representatives, Approved Funds or Affiliates; or (vii) responsible or have any obligation to any other Secured Party to assure that the Collateral exists or is owned by the Loan Parties or is cared for, protected, or insured or has been encumbered, or that the Liens granted to the

Mesa Credit and Guaranty Agreement —Page 106

Administrative Agent therein have been properly or sufficiently or lawfully created, perfected (or continue to be perfected), protected, or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Administrative Agent pursuant to any of the Loan Documents. In addition to and not in limitation of the foregoing, it is understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Administrative Agent may act in any manner it may deem appropriate, in its sole discretion, given the Administrative Agent’s own interest in the Collateral in its capacity as one of the Secured Parties and that the Administrative Agent shall have no other duty or liability whatsoever to any Secured Party as to any of the foregoing, including, without limitation, the preparation, form or filing of any Uniform Commercial Code financing statement, amendment or continuation or of any other type of document related to the creation, perfection, continuation or priority of any Lien as to any property of the Loan Parties.

11.04 Reliance by Administrative Agent. (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, electronic mail message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to any Loan Party), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Secured Parties against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Lenders (or such greater number of Lenders as may be expressly required hereby in any instance) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Secured Parties. Notwithstanding the foregoing, the Administrative Agent shall not be required to take, or to omit to take, any action that is, in the opinion of the Administrative Agent or its counsel, contrary to any Loan Document or applicable Requirement of Law.

(b) For purposes of determining compliance with the conditions specified in Article 4, each Lender that has signed this Agreement (or an addendum or joinder to this Agreement) shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

11.05 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default and/or Event of Default, unless the Administrative Agent shall have received written notice from a Lender or any Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default and/or

Mesa Credit and Guaranty Agreement —Page 107

Event of Default as may be directed by the Required Lenders in accordance with Article 9, provided, that unless and until the Administrative Agent has received any such direction in accordance with Section 11.04, the Administrative Agent may (but shall not be obligated to) take any action, or refrain from taking any action, with respect to such Default and/or Event of Default as it shall deem advisable or in the best interest of the Lenders.

11.06 Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by any Agent-Related Person hereafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrowers and the other Loan Parties hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrowers and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, no Agent-Related Person shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

11.07 Indemnification of Administrative Agent. The Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided, however, that no action taken in furtherance of the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 11.07. Without limitation of the foregoing, each Lender shall reimburse each Agent-Related Person upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by any Agent-Related Person in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this

Mesa Credit and Guaranty Agreement —Page 108

Agreement, any other Loan Document, or any document contemplated by or referred to herein. The obligations of the Lenders hereunder shall not diminish the obligations of the Borrowers to indemnify and reimburse the Agent-Related Parties for such amounts. The Administrative Agent may in its discretion first seek payment from the Lenders hereunder before seeking payment from the Borrowers for such amounts or may seek payments first from the Borrowers. In any event, any amounts received from Borrowers as reimbursement for amounts already reimbursed by Lenders shall be paid to Lenders in accordance with the terms hereof. The undertaking in this Section 11.07 shall survive the Termination Date and the resignation of the Administrative Agent.

11.08 Administrative Agent in its Individual Capacity. Administrative Agent and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan Parties and their respective Affiliates as though Administrative Agent were not the Administrative Agent, Support Provider or an L/C Issuer hereunder and without notice to or consent of any Secured Party. The Secured Parties acknowledge that, pursuant to such activities, Administrative Agent or its Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of such Loan Party or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Loans, Administrative Agent and/or its Affiliates (as applicable) shall have the same rights and powers under this Agreement as any other Secured Party and may exercise such rights and powers as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” include the Administrative Agent and/or its Affiliates (as applicable) in its individual capacity.

11.09 Successor Administrative Agent. The Administrative Agent may resign as the Administrative Agent upon ten (10) days’ notice to the Lenders (or without any such notice if in connection with the consummation of the purchase of certain of the Obligations pursuant an intercreditor arrangement), provided that any such resignation by the Administrative Agent may also constitute its resignation as the L/C Issuer, Support Provider and Swingline Lender (if applicable). If the Administrative Agent resigns under this Agreement, the Required Lenders shall appoint from among the Lenders (or the Affiliates thereof) a successor administrative agent for the Lenders, which successor administrative agent shall (unless an Event of Default has occurred and is continuing) be subject to the approval of the Borrower Representative (which approval shall not be unreasonably withheld or delayed). If no successor administrative agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders, a successor administrative agent from among the Lenders (or the Affiliates thereof). Upon the acceptance of its appointment as successor administrative agent hereunder, the Person acting as such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent (and Support Provider, L/C Issuer and Swingline Lender (if the retiring Administrative Agent desires to resign therefrom)) and the respective terms “Administrative Agent”, “Support Provider, “L/C Issuer and “Swingline Lender” shall mean such successor administrative agent, Letter of Credit issuer, support provider, and swingline lender, and the retiring Administrative Agent’s appointment, powers and duties in such capacities shall be terminated without any other further act or deed on its behalf. After any retiring Administrative

Mesa Credit and Guaranty Agreement —Page 109

Agent’s resignation hereunder as the Administrative Agent, the provisions of this Article 11 and Sections 12.04 and 12.05 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent under this Agreement or while it was actively engaged in transferring its rights and obligations as Administrative Agent to the successor administrative agent. If no successor administrative agent has accepted appointment as the Administrative Agent by the date ten (10) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Required Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor administrative agent as provided for above. No Person may be removed from its capacity as Administrative Agent.

11.10 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan, Letter of Credit Liabilities or Swingline Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Loan Parties) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, Letter of Credit Liabilities, Swingline Exposures and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Secured Parties and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Secured Parties and the Administrative Agent and their respective agents and counsel and all other amounts due the Secured Parties and the Administrative Agent under Sections 2.09 and 12.04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Secured Party to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Secured Parties, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.09 and 12.04.

11.11 Collateral and Guaranty Matters. The Secured Parties irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Guarantor and any Lien on any Collateral granted to or held by the Administrative Agent under any Loan Document (i) upon the Termination Date, (ii) that is transferred or to be transferred as part of or in connection with any Disposition permitted hereunder or under any other Loan Document, or (iii) as approved in accordance with Section 12.01, and to execute in connection with such events such payoff letters and related documentation in form and substance satisfactory to Administrative Agent, in its sole

Mesa Credit and Guaranty Agreement —Page 110

discretion, as shall in Administrative Agent’s sole discretion be deemed advisable. In connection with any such release, each Lender, the L/C Issuer and the Support Providers hereby direct the Administrative Agent, and the Administrative Agent agrees that it shall, upon the reasonable request of the Borrower Representative (and except in the case where the Termination Date has actually occurred, so long as no Default or Event of Default then exists), to (i) promptly execute and deliver or file such documents and perform other actions reasonably requested to release the guaranties and the Liens and (ii) deliver to the Loan Parties any portion of such Collateral so released in the possession of the Administrative Agent or as otherwise required under any Loan Documents or applicable Law, in each case without recourse, representation or warranty. Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of Collateral, pursuant to this Section 11.11.

The Secured Parties hereby irrevocably authorize Administrative Agent (absent, with respect to any particular transaction, Administrative Agent receiving contrary written bidding instructions from the Required Lenders before such transaction), to credit bid all or any portion of the Obligations (including, to credit bid all or any portion of the Obligations (including accepting some or all of the Collateral in satisfaction of some or all of the Obligations pursuant to a deed in lieu of foreclosure or otherwise) and in such manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Collateral (a) at any sale thereof conducted under the provisions of the Bankruptcy Code of the United States, including under Section 363, 1123 or 1129 of the Bankruptcy Code of the United States, or any similar Laws in any other jurisdictions to which a Loan Party is subject, (b) at any other sale or foreclosure or acceptance of collateral in lieu of debt conducted by (or with the consent or at the direction of) Administrative Agent (whether by judicial action or otherwise) in accordance with any applicable Law. In connection with any such credit bid and purchase, the Obligations owed to the Secured Parties shall be entitled to be, and shall be, credit bid on a ratable basis (with Obligations with respect to contingent or unliquidated claims receiving contingent interests in the acquired assets on a ratable basis that would vest upon the liquidation of such claims in an amount proportional to the liquidated portion of the contingent claim amount used in allocating the contingent interests) in the asset or assets so purchased (or in the Capital Stock or debt instruments of the acquisition vehicle or vehicles that are used to consummate such purchase). In connection with any such bid Administrative Agent shall be authorized (i) to form one or more acquisition vehicles to make a bid, (ii) to adopt documents providing for the governance of the acquisition vehicle or vehicles (provided that any actions by Administrative Agent with respect to such acquisition vehicle or vehicles, including any disposition of the assets or Capital Stock thereof shall be governed, directly or indirectly, by the vote of the Required Lenders, irrespective of the termination of this Agreement and without giving effect to the limitations on actions by the Required Lenders contained in clauses (a) through (h) of Section 12.01 of this Agreement (provided that, in any event, the consent of each Lender shall be required for any amendment that would treat or attempts to treat a Lender or a class of Lenders in a manner different than all other Lenders), and (iii) to the extent that Obligations that are assigned to an acquisition vehicle are not used to acquire Collateral for any reason (as a result of another bid being higher or better, because the amount of Obligations assigned to the acquisition vehicle exceeds the amount of debt credit bid by the acquisition vehicle or otherwise), such Obligations shall automatically be reassigned to the Lenders pro rata and the Capital Stock and/or debt instruments issued by any acquisition vehicle on account of the Obligations that had been

Mesa Credit and Guaranty Agreement —Page 111

assigned to the acquisition vehicle shall automatically be cancelled, without the need for any Secured Party or any acquisition vehicle to take any further action.

11.12 Other Agents; Arrangers and Managers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” “documentation agent,” “co-agent,” “book manager,” “lead manager,” “arranger,” “lead arranger” or “co-arrange?” (each, an “Additional Titled Agent”) shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than, in the case of such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, no Additional Titled Agent shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any Additional Titled Agent in deciding to enter into this Agreement or in taking or not taking action hereunder. At any time that any Lender serving as an Additional Titled Agent shall have transferred to any other Person (other than any Affiliates) all of its interests in the Loans, such Lender shall be deemed to have concurrently resigned as such Additional Titled Agent.

11.13 Additional Secured Parties. The benefit of the provisions of the Loan Documents directly relating to the Collateral or any Lien granted thereunder shall extend to and be available to any Secured Party that is not a Lender, L/C Issuer or Support Provider as long as, by accepting such benefits, such Secured Party agrees, as among the Administrative Agent and all other Secured Parties, that such Secured Party is bound by (and, if requested by the Administrative Agent, shall confirm such agreement in a writing in form and substance acceptable to the Administrative Agent) this Article 11, Section 2.13 (Sharing of Payments), Section 12.08 (Confidentiality) and Section 12.09 (Setoff) as each may be in effect from time to time, and the decisions and actions of the Administrative Agent and the Required Lenders (or, where expressly required by the terms of this Agreement, a greater proportion of the Lenders) to the same extent a Lender is bound, provided, however, that, notwithstanding the foregoing, (a) such Secured Party shall be bound by Section 11.07 (Indemnification of Administrative Agent) only to the extent of liabilities, costs and expenses with respect to or otherwise relating to the Collateral held for the benefit of such Secured Party, in which case the obligations of such Secured Party thereunder shall not be limited by any concept of ratability or similar concept, (b) except as set forth specifically herein as to such Secured Party (rather than the Secured Parties generally), each of the Administrative Agent, the Lenders, the L/C Issuers and the Support Providers shall be entitled to act at its sole discretion, without regard to the interest of such Secured Party, regardless of whether any Obligation to such Secured Party thereafter remains outstanding, is deprived of the benefit of the Collateral, becomes unsecured or is otherwise affected or put in jeopardy thereby, and without any duty or liability to such Secured Party or any such Obligation and (c) except as set forth specifically herein as to such Secured Party (rather than the Secured Parties generally), such Secured Party shall not have any right to be notified of, consent to, direct, require or be heard with respect to, any action taken or omitted in respect of the Collateral or under any Loan Document.

11.14 Exclusive Right to Enforce Rights and Remedies. Notwithstanding anything to the contrary contained herein or in any other Loan Document, the authority to enforce rights and remedies hereunder and under the other Loan Documents against the Loan Parties or any of them or in respect of the Collateral are hereby granted to, and shall be vested exclusively in, and all actions and Proceedings in connection with any such enforcement shall be instituted and maintained

Mesa Credit and Guaranty Agreement —Page 112

exclusively by, Administrative Agent (or its agents or designees) in accordance with the Loan Documents for the benefit of the applicable Secured Parties; provided that the foregoing shall not prohibit (i) the Administrative Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent) hereunder and under the other Loan Documents, (ii) each of the L/C Issuer, any Support Provider and the Swingline Lender from exercising the rights and remedies that inure to its benefit (solely in its capacity as L/C Issuer, Support Provider or Swingline Lender, as the case may be) hereunder and under the other Loan Documents, (iii) any Lender or Participant from exercising setoff rights in accordance with Section 12.09, (iv) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a Proceeding relative to any Loan Party under any Bankruptcy Code or other Debtor Relief Law or (v) any Lender or other Secured Party from exercising any express right or remedy of such Lender under the Loan Documents where the Administrative Agent does not have the power and authority under the Loan Documents to act on behalf of such Lender or other Secured Party; and provided, further, that if at any time there is no Person acting as the Administrative Agent hereunder and under the other Loan Documents, then (A) the Required Lenders shall have the rights otherwise ascribed to the Administrative Agent pursuant to Section 9.02 and (B) in addition to the matters set forth in Section 11.04 and Section 12.09, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

Borrowers hereby agree that so long as a Loan Party is the issuer of any outstanding debt or equity securities that are registered or issued pursuant to a Rule 144A private offering or is actively contemplating issuing any such securities it will, if requested by the Administrative Agent, use commercially reasonable efforts to identify that portion of the Borrower Materials that may be distributed to the Public Lenders and that (w) all such Borrower Materials shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower

Mesa Credit and Guaranty Agreement —Page 116

Materials “PUBLIC,” the Loan Parties shall be deemed to have authorized the Administrative Agent and the Lenders to treat such Borrower Materials as not containing any material nonpublic information (although it may be sensitive and proprietary) with respect to any Loan Party or its securities for purposes of United States Federal and state securities laws (provided, however, that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 12.08); (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of any E-System designated “Public Side Information”; and (z) the Administrative Agent shall treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of any E-System not designated “Public Side Information.” Notwithstanding the foregoing, Borrowers shall be under no obligation to xxxx the Borrower Materials “PUBLIC.”

12.03 No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

The Borrowers agree (a) to pay or reimburse the Administrative Agent for all reasonable documented out-of-pocket costs and expenses incurred in connection with the development, preparation, negotiation and execution of this Agreement and the other Loan Documents and any amendment, waiver, consent or other modification of the provisions hereof and thereof (whether or not the transactions contemplated hereby or thereby are consummated), and the consummation, syndication and administration of the transactions contemplated hereby and thereby, including all reasonable documented out-of-pocket Attorney Costs and costs and expenses in connection with the use of IntraLinks, SyndTrak, StuckyNet, or other similar information transmission systems in connection with this Agreement (each being an “E-System”), and (b) to pay or reimburse the Administrative Agent, the L/C Issuer and each Support Provider and each Lender for all reasonable documented out-of-pocket costs and expenses incurred in connection with the enforcement, attempted enforcement, or preservation of any rights following the occurrence and during the continuance of a Default or an Event of Default or the exercise of remedies under this Agreement or the other Loan Documents (including all such costs and expenses incurred during any “workout” or restructuring in respect of the Obligations and during any legal proceeding, including any proceeding under any Debtor Relief Law), including all Attorney Costs.

All amounts due under this Section 12.04 shall be deemed part of the Obligations when incurred and

Mesa Credit and Guaranty Agreement —Page 117

shall be payable within ten (10) Business Days after demand therefor. The agreements in this Section 12.04 shall survive the Termination Date.

12.05 Indemnification by the Loan Parties. The Loan Parties agree jointly and severally to indemnify and hold harmless each Agent-Related Person, each Lender, the L/C Issuer, Support Providers, each Secured Party and the respective Affiliates of all such Persons, and the directors, officers, employees, counsel, trustees, advisors, agents, financing sources, managed funds, controlling persons, attorneys-in-fact, and members of all of the foregoing Persons (collectively, the “Indernnitees”) from and against any and all liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements (including Attorney Costs incurred by each Indemnitee and other costs of investigation or defense, including those incurred upon any appeal), of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with (a) the execution, delivery, enforcement, performance, syndication or administration of any Loan Document or any other agreement, letter or instrument delivered in connection with the transactions contemplated thereby or the consummation of the transactions contemplated thereby, (b) any Commitment, Loan or Letter of Credit or Support Agreement or the use or proposed use of the proceeds therefrom (including any refusal by any L/C Issuer to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (c) any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by any Borrower, any Subsidiary or any other Loan Party, or any Environmental Liability related in any way to any Borrower, any Subsidiary or any other Loan Party, or (d) any actual or prospective claim, litigation, investigation or Proceeding relating to any of the foregoing, whether based on contract, tort or any other theory (including any investigation of, preparation for, or defense of any pending or threatened claim, investigation, litigation or proceeding), whether brought by a third party or by any Loan Party, and regardless of whether any Indemnitee is a party thereto (all the foregoing, collectively, the “Indemnified Liabilities”), provided, that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements (w) are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. No Indemnitee shall be liable for any damages arising from the use by others of any information or other materials obtained through the Internet or any E-System in connection with this Agreement, nor shall any Indemnitee have any liability for any punitive, special, indirect or consequential damages relating to this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether arising or occurring before or after the Closing Date). All amounts due under this Section 12.05 shall be payable within ten (10) Business Days after demand therefor. The agreements in this Section 12.05 shall survive the resignation of the Administrative Agent, the replacement of any Lender and the Termination Date. To the extent that the indemnification set forth in this Section 12.05 may be unenforceable, each Loan Party shall contribute the maximum portion which it is permitted to pay and satisfy under applicable Law to the payment and satisfaction of all such indemnified liabilities incurred by the Indemnitees or any of them. Without limiting the generality of any provision of this Section 12.05, to the fullest extent permitted by law, each Loan Party hereby waives all rights for contribution or any other rights of recovery with respect to liabilities, losses, damages, costs and expenses arising under or relating to Environmental

Mesa Credit and Guaranty Agreement —Page 118

Laws that it might have by statute or otherwise against any Indemnitee, except to the extent that such items are determined by a final and non-appealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. No Loan Party shall, without the prior written consent of each applicable Indemnitee, effect any settlement of any pending or threatened proceedings in respect of which indemnity could have been sought hereunder by such Indemnitee unless such settlement (i) includes an unconditional release of such Indemnitee in form and substance reasonably satisfactory to such Indemnitee from all liability or claims that are the subject matter of such proceedings and (ii) does not include any statement as to or any admission of fault, culpability, wrong doing or a failure to act by or on behalf of any Indemnitee. This Section 12.05 shall not apply with respect to Taxes other than any Taxes that represent liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements arising from any non-Tax related Indemnified Liability.

12.06 Payments Set Aside. To the extent that any payment by or on behalf of any Loan Party is made to the Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right of set-off, and such payment or the proceeds of such set-off 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 the Administrative Agent or such Lender in its discretion) to be repaid or turned-over 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 (along with any Lien previously terminated with respect to such obligation) shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, the Termination Date had not occurred and such termination had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share 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. The provisions of this paragraph shall survive any termination of this Agreement.

12.07 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, the Indemnitees and to the extent provided in Section 11.13 each other Secured Party, provided that (x) neither any Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and (y) no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this Section 12.07, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section 12.07 or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section 12.07 (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 subsection (d) of this Section 12.07, the Indemnitees and to the extent provided in

Mesa Credit and Guaranty Agreement —Page 119

Section 11.13 each other Secured Party) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of a Lender, no minimum amount need be assigned; and

(B) in any case not described in subsection (b)(i)(A) of this Section 12.07, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $1,000,000, in the case of any assignment of a Revolving Commitment, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower Representative, otherwise consents (each such consent not to be unreasonably withheld, conditioned or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate tranches or facilities on a non-pro rata basis.

(iii) Required Consents. The consent of the Administrative Agent shall be required for any assignment. No consent of any other party shall be required for any assignment except (A) to the extent required by subsection (b)(i)(B) of this Section 12.07 and (B) the consent of the Borrower Representative (such consent not to be unreasonably withheld, conditioned or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund of a Lender, provided that the Borrower Representative shall be deemed to have consented to any such assignment if the Administrative Agent has not received an objection thereto in writing within ten (10) Business Days after the Borrower Representative’s receipt of notice of such assignment.

Mesa Credit and Guaranty Agreement —Page 120

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 (unless waived by the Administrative Agent at its sole option), and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to certain Persons. No such assignment may be made to any Loan Party or any Defaulting Lender or any of their respective Affiliates or Subsidiaries. No such assignment shall be made to a natural person. No such Assignment may be made to any Person that owns a greater than 50% equity investment in a Certificated Air Carrier.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section 12.07, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, 12.04 and 12.05 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request of the assignee Lender made itself or through the Administrative Agent, the Borrowers (at their expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection 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 subsection (d) of this Section 12.07.

For purposes of determining compliance with Section 12.07(b)(v), the Administrative Agent and assigning Lender may rely upon the representations and warranties of the proposed assignee Lender; it being agreed that neither the Administrative Agent nor any assigning Lender shall have any duty of inquiry to determine such compliance.

(c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrowers (the “Registrar”), shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, the principal amounts of the Loans owing to, and the Letter of Credit Liabilities and Swingline Exposure held by, each Lender pursuant to the terms hereof from time to time (the “Register”). No assignment or transfer of a Loan or a Commitment (other than a pledgee described in subsection (f) below) shall be effective unless and until registered in the Register. The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by any Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. Each Borrower hereby

Mesa Credit and Guaranty Agreement —Page 121

designates the entity serving as the Administrative Agent to serve as such Borrower’s non-fiduciary agent solely for purposes of maintaining the Register as provided in this Section, and each Borrower hereby agrees that the entity serving as Registrar and its Affiliates, and their respective officers, directors, employees and agents shall constitute Indemnitees under Section 12.05. At the written request of the registered Lender, the Registrar shall note a collateral assignment of a Loan on the Register as described in subsection (f) below and, provided that the Registrar has received the name and address of such collateral assignee, the Registrar (i) shall not permit any further transfers of the Loan on the Register absent receipt of written consent to such transfers from such collateral assignee and (ii) shall record the transfer of the Loan on the Register to such collateral assignee (or such collateral assignee’s designee, nominee or assignee) upon written request by such collateral assignee and compliance with the other provisions of this Agreement governing collateral assignments.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower Representative, any Loan Party, the Administrative Agent, the L/C Issuer, the Support Provider or the Swingline Lender, sell participations to any Person (other than a natural person or any Loan Party (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 Commitment and/or the Loans owing to it (including such Lender’s Letter of Credit Liabilities and Swingline Exposure)), 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) each Borrower, each other Loan Party, the Administrative Agent and the Lenders, the L/C Issuer and Swingline Lender shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement, provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso of Section 12.01 (clauses (a) through (g)) that affects such Participant. Subject to subsection (e) of this Section, each Borrower and each other Loan Party agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.09 as though it were a Lender, provided such Participant agrees to be subject to Section 2.13 as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or other Obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such

Mesa Credit and Guaranty Agreement —Page 122

Commitment, Loan, Letter of Credit or other Obligation is in registered form under Section 51103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 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 Representative’s prior written consent and such Participant shall in any event be subject to replacement pursuant to Section 12.15 in the event it exercises such rights. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower Representative is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 3.01 as though it were a Lender.

(f) 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 and any pledge to a trustee as security for the benefit of the noteholders and other securityholders or creditors of a Lender, 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 until the provisions of this Section regarding assignment are satisfied with respect to such pledge or assignment.

(g) Consent to Disclosure; Cooperation of Loan Parties. Subject to the provisions of Section 12.08, each Loan Party authorizes each Lender to disclose to any prospective participant or assignee of a Commitment or Loan, any and all information in such Lender’s possession concerning the Loan Parties and their financial affairs which has been delivered to such Lender by or on behalf of the Loan Parties pursuant to this Agreement, or which has been delivered to such Lender by or on behalf of the Loan Parties in connection with such Lender’s credit evaluation of the Loan Parties prior to entering into this Agreement. If necessary, each Loan Party agrees to (i) execute any documents (including new Revolving Notes) reasonably required to effectuate and acknowledge each assignment of a Commitment or Loan to an assignee in accordance with Section 12.07, (ii) make the Loan Parties’ management available to meet with the Administrative Agent and prospective participants and assignees of Commitments or Loans and (iii) assist the Administrative Agent or the Lenders in the preparation of information relating to the financial affairs of the Loan Parties as any prospective participant or assignee of a Commitment or Loan reasonably may request.

12.08 Confidentiality.

(a) Each Loan Party acknowledges that (i) from time to time financial advisory, investment banking and other services may be offered or provided to it (in connection with this Agreement or otherwise) by each Lender or by one or more affiliates of such Lender

Mesa Credit and Guaranty Agreement —Page 123

and (ii) information delivered to each Lender by the Loan Parties may be provided to each such affiliate, it being understood that any such affiliate receiving such information shall be bound by the provisions of Section 12.08(b) as if it were a Lender under this Agreement.

(b) Each of the Administrative Agent and each Lender severally (and not jointly) agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its Affiliates and Approved Funds and to its and its Affiliates’ and Approved Funds’ respective partners, directors, officers, employees, agents, consultants, counsel, accountants, advisors, controlling persons, managed funds, financing sources, actual and prospective investors, and other representatives who Administrative Agent reasonably believes need to know such Information in connection with the transactions contemplated by this Agreement (collectively, the “Representatives”) (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), or to Rating Agencies, (ii) to the extent requested or required by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), including, without limitation, any regulatory filings, (iii) to the extent required by applicable Laws or by any subpoena or similar judicial or legal process, (iv) to any other party to the Loan Documents, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or Proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) to (A) any actual or prospective assignee of a Lender, assignee or successor of Administrative Agent, or pledgee of or Participant in any of its rights or obligations under this Agreement, or (B) any actual or prospective counterparty to any swap or derivative transaction relating to any Borrower or any other Loan Party and its obligations, provided that such parties agree to be bound by confidentiality provisions substantially similar to those hereunder, and to the Representatives of the foregoing parties in clauses (A) and (B), (vii) with the consent of the Borrower Representative, (viii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Administrative Agent, any Lender, or any of their respective Representatives on a non-confidential basis from a source other than the Loan Parties not known by such party to be bound by a duty of confidentiality to any Loan Party or (ix) for purposes of establishing a due diligence defense. The terms of this provision shall supersede and replace any previous agreement regarding the confidentiality of the Information and, other than with respect to Material Contracts, shall terminate upon the later of (x) termination of the Commitments and the payment of the Obligations and (y) two (2) years following the disclosure of such information.

For purposes of this Section, (i) “Information” means, all information received from any Loan Party or any of its Subsidiaries relating to any Loan Party or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to or in the possession of the Administrative Agent, any other Secured Party or their Representatives on a non-confidential basis prior to disclosure by any Loan Party or any of its Subsidiaries, as evidenced by contemporaneous written records, and (ii) “Rating Agencies” means Xxxxx’x, S&P, Xxxxx Ratings Ltd., or any other nationally recognized rating agency or service. 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

Mesa Credit and Guaranty Agreement —Page 124

to its own confidential information. Notwithstanding anything herein to the contrary, “Information” shall not include, and the Administrative Agent and each other Secured Party may disclose without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such other Secured Party relating to such tax treatment and tax structure, provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans and transactions contemplated hereby.

(c) No Borrower or Affiliate thereof will issue any press releases or other public disclosure using the name of the Administrative Agent or its Affiliates or any other Lender or its Affiliates or referring to this Agreement or the other Loan Documents without at least three (3) Business Days’ prior notice to Administrative Agent or such Lender and without the prior written consent of Administrative Agent or such Lender, which consent shall not be unreasonably withheld, conditioned or delayed, unless (and only to the extent that) such Borrower or Affiliate is required to do so under law and then, in any event, such Borrower or Affiliate will consult with such Lender before issuing such press release or other public disclosure. The Borrowers hereby consent to the publication by any Secured Party of a tombstone or similar advertising material relating to the financing transactions contemplated by this Agreement (such material may, without limitation, include a description of the Loan Parties and the use of any identifying trademark or other marks of a Loan Party). Each Secured Party reserves the right to provide to industry trade organizations information necessary and customary for inclusion in league table measurements.

12.09 Set-off. In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and during the continuance of any Event of Default, each Lender and any Affiliate of a Lender is authorized at any time and from time to time, with the prior written consent of the Administrative Agent, but without prior notice to the Borrowers or any other Loan Party (any such notice being waived by the Borrowers on their own behalf and on behalf of each Loan Party), to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender or such Affiliate to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to such Lender hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or indebtedness. Each Lender agrees promptly to notify the Borrowers and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. Any Lender exercising a right to set-off shall purchase for cash (and the other Lenders shall sell) interests in each of such other Lender’s Pro Rata Share of the Obligations as would be necessary to cause all Lenders to share the amount so set-off with each other Lender in accordance with their respective Pro Rata Share of the Obligations.

Mesa Credit and Guaranty Agreement —Page 125

12.10 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrowers. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

12.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

12.12 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter, including the Commitment Letter (other than in respect of any terms that expressly survive the termination or expiration thereof following the delivery of this Agreement), provided that the Fee Letter shall survive the effectiveness of this Agreement and the initial Credit Extensions hereunder and shall continue to be in full force and effect after the Closing Date in accordance with their terms. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control, provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof

12.13 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied.

12.14 Severability. If any provision of this Agreement or any other Loan Document is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The

Mesa Credit and Guaranty Agreement —Page 126

invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12.15 Replacement of Lenders. If (i) any Lender requests compensation under Section 3.04, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, unless such Lender has waived its right to such additional amount, (iii) a Lender (a “Non-Consenting Lender”) does not consent to a proposed change, waiver, discharge or termination with respect to any Loan Document that has been approved by the Required Lenders as provided in Section 12.01 but requires unanimous consent of all Lenders or all Lenders directly affected thereby (as applicable), (iv) it is, and continues to be, unlawful for any Lender to fund or maintain LIBOR Loans, as provided in Section 3.02, or (v) any Lender is a Defaulting Lender, then Administrative Agent or the Borrower Representative may, at its sole option, expense and effort, and upon notice to such Lender and, in the case of an election made by the Borrower Representative, 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 12.07), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) the Borrowers shall have paid to the Administrative Agent the assignment fee specified in Section 12.07(b), if any;

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and Unreimbursed Amounts, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts);

(c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter;

(d) such assignment does not conflict with applicable Laws; and

(e) in the case of any such assignment resulting from a Non-Consenting Lender’s failure to consent to a proposed change, waiver, discharge or termination with respect to any Loan Document, the applicable replacement Lender consents to the proposed change, waiver, discharge or termination, provided that the failure by such Non-Consenting Lender to execute and deliver an Assignment and Assumption shall not impair the validity of the removal of such Non-Consenting Lender and the mandatory assignment of such Non-Consenting Lender’s Commitments and outstanding Loans and participations in outstanding Letters of Credit pursuant to this Section 12.15 shall nevertheless be effective without the execution by such Non-Consenting Lender of an Assignment and Assumption.

Mesa Credit and Guaranty Agreement —Page 127

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 Borrowers or Administrative Agent to require such assignment and delegation cease to apply.

12.16 Governing Law.

(a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO AND THERETO SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CONFLICTS OF LAW PRINCIPLES THEREOF THAT WOULD CALL FOR THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION.

(b) Each Loan Party irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against any Secured Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum other than the courts of the State of New York sitting in New York County, and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by applicable law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document shall affect any right that any Secured Party may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Loan Party or its properties in the courts of any jurisdiction. Each Loan Party hereby irrevocably waives, to the fullest extent not prohibited by applicable law, any objection that it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

12.17 Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CON TRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

12.18 USA Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Loan Parties, which information includes the name and address of the Loan Parties and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Loan Parties in accordance with the Patriot Act.

12.19 Nonliability of Lenders. The relationship between the Loan Parties on the one hand and the Lenders and the Administrative Agent on the other hand shall be solely that of borrower or guarantor, as applicable, and lender. Neither the Administrative Agent nor any Lender or other Secured Party has any fiduciary relationship with or duty to any Loan Party arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Loan Parties, on the one hand, and the Administrative Agent and the Lenders and other Secured Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor. Neither the Administrative Agent nor any Lender or any other Secured Party undertakes any responsibility to any Loan Party to review or inform any Loan Party of any matter in connection with any phase of any Loan Party’s business or operations. The Loan Parties agree that neither the Administrative Agent nor any Lender or other Secured Party shall have liability to any Loan Party (whether sounding in tort, contract or otherwise) for losses suffered by any Loan Party in connection with, arising out of, or in any way related to the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought.

NO SECURED PARTY SHALL BE LIABLE FOR ANY DAMAGES ARISING FROM THE USE BY OTHERS OF ANY INFORMATION OR OTHER MATERIALS OBTAINED THROUGH INTRALINKS OR OTHER SIMILAR INFORMATION TRANSMISSION SYSTEMS IN CONNECTION WITH THIS AGREEMENT, NOR SHALL ANY SECURED PARTY HAVE ANY LIABILITY WITH RESPECT TO, AND THE BORROWER REPRESENTATIVE ON BEHALF OF ITSELF AND EACH OTHER LOAN PARTY, HEREBY WAIVES, RELEASES AND AGREES NOT TO XXX FOR ANY SPECIAL, PUNITIVE, INDIRECT OR CONSEQUENTIAL DAMAGES RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ARISING OUT OF ITS ACTIVITIES IN CONNECTION HEREWITH OR THEREWITH (WHETHER BEFORE OR AFTER THE CLOSING DATE).

The Loan Parties acknowledge that they have been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents to which it is a party. No joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Agents, Lenders or among the Loan Parties and the Lenders and the Agents. The Loan Parties further acknowledge that each Lender or one or more of its affiliates may be a financial and securities firm and that such Lender or such affiliates may from time to time effect transactions, for its own or its affiliates’ account or the account of customers, and hold positions in loans, securities or options on loans or securities of a Loan Party and its affiliates and of other companies that may be the subject of the transactions contemplated by this Agreement.

ARTICLE 13

APPOINTMENT OF THE BORROWER REPRESENTATIVE; JOINT AND SEVERAL

LIABILITY OF THE BORROWERS; SUBORDINATION

13.01 Borrower Representative. Eneh Borrower hereby irrevocably appoints the Borrower Representative, as the agent for such Borrower on its behalf, to (i) request Loans from the Lenders, (ii) request L/C issuer to issue Letters of Credit and Support Providers to issue Support Agreements, (iii) to give and receive notices under the Loan Documents and (iv) take all other action which the Borrower Representative or the Borrowers are permitted or required to take under this Agreement.

13.02 Joint and Several Liability of Borrowers.

(a) Joint and Several Liability. Each Borrower hereby agrees that such Borrower is jointly and severally liable for, and hereby absolutely and unconditionally guarantees to the Administrative Agent and other Secured Parties and their respective successors and assigns, the full and prompt payment (whether at stated maturity, by acceleration or otherwise) and performance of, all Obligations owed or hereafter owing to the Administrative Agent and other Secured Parties by each other Borrower. Each Borrower agrees that its guaranty obligation hereunder is a continuing guaranty of payment and performance and not of collection, that its obligations under this Section 13.02 shall not be discharged until payment and performance, in full, of the Obligations has occurred, and that its obligations under this Section 13.02 shall be absolute, unconditional and irrevocable, irrespective of, and unaffected by, (i) the genuineness, validity, regularity, enforceability or any future amendment of, or change in, any Obligation or any agreement, document or instrument to which any Borrower is or may become a party; (ii) the absence of any action to enforce any Obligation or the waiver or consent by the Administrative Agent or any other Secured Party with respect to any of the provisions governing any Obligation; (iii) the insolvency of any Borrower or Subsidiary; and (iv) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor. Each Borrower shall be regarded, and shall be in the same position, as principal debtor with respect to the Obligations guaranteed hereunder.

(b) Waivers by Borrowers. Each Borrower expressly waives all rights it may have now or in the future under any statute, or at common law, or at law or in equity, or otherwise, to compel the Administrative Agent or other Secured Parties to marshal assets or to proceed in respect of the Obligations guaranteed hereunder against any other Borrower or Subsidiary, any other party or against any security for the payment and performance of the Obligations before proceeding against, or as a condition to proceeding against, such Borrower. Each Borrower consents and agrees that the Administrative Agent or the other Secured Parties may, at any time and from time to time, without notice or demand, whether before or after an actual or purported termination, repudiation or revocation of this Agreement by any Borrower, and without affecting the enforceability or continuing effectiveness hereof as to such Borrower: (i) with the consent of the other Borrowers, supplement, restate, modify, amend, increase, decrease, extent, renew or otherwise change the time for payment or the terms of this Agreement or any part thereof, including any increase or decrease of the rate(s) of interest thereon; (ii) with the consent of the other Borrowers, supplement, restate, modify, amend, increase, decrease, or

Mesa Credit and Guaranty Agreement —Page 131

enter into or give any agreement with respect to, this Agreement or any part thereof, or any of the Security Documents; (iii) waive, approve or consent to any action, condition, covenant, default, remedy, right, representation or term of this Agreement or any other Loan Document; (iv) accept partial payments; (v) release, reconvey, terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute, transfer or enforce any security or guarantees, and apply any security and direct the order or manner of sale thereof as the Agents or Lenders in their sole and absolute discretion may determine; (vi) release any person from any personal liability with respect to this Agreement or any part thereof; (vii) settle, release on terms satisfactory to the Required Lenders or by operation of applicable Laws or otherwise liquidate or enforce any security or guaranty in any manner, consent to the transfer of any security and bid and purchase at any sale; or (viii) consent to the merger, change or any other restructuring or termination of the corporate or partnership existence of any Borrower or any other person, and correspondingly restructure the obligations evidenced hereby, and any such merger, change, restructuring or termination shall not affect the liability of any Borrower or the continuing effectiveness hereof, or the enforceability hereof with respect to all or any part of the obligations evidenced hereby. It is agreed among each Borrower, the Administrative Agent and Lenders that the foregoing consents and waivers are of the essence of the transaction contemplated by this Agreement and the other Loan Documents and that, but for the provisions of this Section 13.02 and such waivers, the Administrative Agent and Lenders would decline to enter into this Agreement.

(c) Benefit of Guaranty. Each Borrower agrees that the provisions of this Section 13.02 are for the benefit of the Administrative Agent and the other Secured Parties and their respective successors, transferees, endorsees and assigns, and nothing herein contained shall impair, as between any other Borrower and the Administrative Agent or the other Secured Parties, the obligations of such other Borrower under the Loan Documents.

(d) Waiver of Subrogation, Etc. Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, each Borrower hereby expressly and irrevocably waives any and all rights at law or in equity to subrogation, reimbursement, exoneration, contribution, indemnification or set off and any and all defenses available to a surety, guarantor or accommodation co-obligor, including, without limitation, any defense based upon any statute or rule of law that provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal, and any defense of the statute of limitations in any action hereunder or in any action for the collection or performance of any obligations hereby guaranteed. Each Borrower acknowledges and agrees that this waiver is intended to benefit the Administrative Agent and Lenders and other Secured Parties and shall not limit or otherwise affect such Borrower’s liability hereunder or the enforceability of this Section 13.02, and that the Administrative Agent, the Lenders and the other Secured Parties and their respective successors and assigns are intended third party beneficiaries of the waivers and agreements set forth in this Section 13.02(d).

(e) Election of Remedies. If the Administrative Agent or any other Secured Party may, under applicable law, proceed to realize its benefits under any of the Loan Documents, the Administrative Agent or any other Secured Party may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of its rights and remedies under this Section 13.02. If, in the exercise of any of its rights and remedies, the Administrative Agent or any other Secured Party shall forfeit any of its rights or remedies, including its right to enter a

Mesa Credit and Guaranty Agreement —Page 132

deficiency judgment against any Borrower or any other Person, whether because of any applicable laws pertaining to “election of remedies” or the like, each Borrower hereby consents to such action by the Administrative Agent or such other Secured Party and waives any claim based upon such action, even if such action by the Administrative Agent or such other Secured Party shall result in a full or partial loss of any rights of subrogation that each Borrower might otherwise have had but for such action by the Administrative Agent or such other Secured Party. Any election of remedies that results in the denial or impairment of the right of the Administrative Agent or any other Secured Party to seek a deficiency judgment against any Borrower shall not impair any other Borrower’s obligation to pay the full amount of the Obligations.

(f) Liability Cumulative. The liability of Borrowers under this Section 13.02 is in addition to and shall be cumulative with all liabilities of each Borrower to the Administrative Agent and Lenders under this Agreement and the other Loan Documents to which such Borrower is a party or in respect of any Obligations or obligation of the other Borrower, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

(g) Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Borrowers under this Agreement is stayed upon the insolvency, bankruptcy or reorganization of any of the Borrowers, all such amounts otherwise subject to acceleration under the terms of this Agreement shall nonetheless be payable jointly and severally by the Borrower hereunder forthwith on demand by the Administrative Agent made at the request of the Required Lenders.

(h) Benefit to Borrowers. All of the Borrowers and their Subsidiaries are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of each such Person has a direct impact on the success of each other Person. Each Borrower and each Subsidiary will derive substantial direct and indirect benefit from the extension of credit hereunder.

13.03 Subordination to Payment of Obligations. Each Loan Party hereby subordinates any Indebtedness of any Loan Party or any Subsidiary to such Loan Party to the full and indefeasible payment in full in cash of the Obligations (and any Lien now or hereafter securing such Indebtedness is hereby subordinated in priority to the Liens of Administrative Agent now or hereafter securing any of the Obligations) and any such Indebtedness collected or received by such Loan Party after an Event of Default has occurred and is continuing shall be held in trust for the Administrative Agent for its benefit and the benefit of the Secured Parties to be credited and applied against the Obligations, but without affecting, impairing or limiting in any manner the liability of such Loan Party under any other provision hereof. No Loan Party shall exercise any remedy with respect to such Indebtedness prior to Termination Date.

Maintenance Burn Factor

“Maintenance Burn Factor” for any Eligible On-wing Engine, on any date of determination, means an amount equal to the sum of the Engine Overhaul Amount and the LLP Refurbishment Amount.

“Engine Overhaul Amount” means, on any date of determination, an amount equal to (i) US$100 (the “Engine Overhaul Rate”) multiplied by (ii) the number of engine flight hours of operation of the Eligible On-wing Engine since (x) the date of the last Engine Overhaul of such Eligible On-wing Engine or (y) the date of the most recent physical maintenance and specification adjusted Appraisal of such Eligible On-wing Engine, whichever is more recent. The Engine Overhaul Rate described above is in 2016 US Dollars, and shall be increased for inflation on January 1 of each calendar year (commencing January 1, 2017) by a percentage amount equal to three percent (3%) by adding: (i) the product of (x) the then current Engine Overhaul Rate multiplied by (y) the value of .03, and (ii) the then current Engine Overhaul Rate, as the same has been previously increased in accordance with this paragraph. In addition to the annual escalation set forth in this paragraph, Administrative Agent may further modify the Engine Overhaul Rate as may be necessary, in its reasonable discretion, to reflect any changes in rates or costs for an Engine Overhaul and for changes in Mesa’s operation of the Engine, including, but not limited to, repetitive operations in harsh environments (which shall be defined as any airport location considered by the engine Manufacturer’s severity standards to possess any or all of the following characteristics: high temperature, high altitude, polluted, xxxxx or desert environments) (“Harsh Operating Conditions”).

“LLP Refurbishment Amount” means, on any date of determination, an amount equal to (i) US$100 (the “LLP Refurbishment Rate”) multiplied by (ii) the number of flight cycles of operation of the Eligible On-wing Engine since the date of the most recent physical maintenance and specification adjusted Appraisal of such Eligible On-wing Engine. The LLP Refurbishment Rate described above is in 2016 US Dollars, and shall be increased for inflation on January 1 of each calendar year (commencing January 1, 2017) so that it equals the sum of the then current Cost Per Cycle of each Engine life limited part. The “Cost Per Cycle” of each such Engine life limited part of such Eligible On-wing Engine shall be determined by dividing (x) the then current manufacturer’s catalogue list price of each Engine life limited part by (y) the Engine manufacturer’s then published Chapter 5 Life for each respective Engine life limited part. In addition to the annual escalation set forth in this paragraph, Administrative Agent may further modify the LLP Refurbishment Rate as may be necessary, in its reasonable discretion, to reflect any changes in rates or costs for an LLP Refurbishment and for changes in Mesa’s operation of the Engine, including, but not limited to, Harsh Operating Conditions.

“Engine Overhaul” means any engine shop visit having a workscope that at a minimum, includes a complete refurbishment or full overhaul of the high pressure compressor module and high pressure turbine module and combustion module section of the relevant Engine, accomplished in accordance with the Engine manufacturer’s Workscope Planning Guide applicable to the Engine.
