WHEREAS, the Borrower has requested that the Lenders make available a $155,000,000 revolving credit and letter of credit facility to provide for (i) the working capital requirements and general corporate purposes of the Borrower and its Subsidiaries, (ii) the refinancing of existing debt of the Loan Parties, (iii) the payment of fees and expenses in connection with the transactions contemplated hereunder and the other Loan Documents and (iv) the financing of Capital Expenditures, including for the purchase of certain vessels and improvements thereto and related mobilization costs;

WHEREAS, the Borrower has requested that the Lenders and the Issuing Lenders make available, for the purposes specified in this agreement, such revolving credit and letter of credit facility, all on the terms and conditions set forth herein; and

WHEREAS, the Lenders and the Issuing Lenders are willing to make available to the Borrower such credit facilities, upon the terms and subject to the conditions set forth herein;

NOW, THEREFORE, in consideration of the premises and the agreements hereinafter set forth, the parties hereto hereby agree as follows:

ARTICLE I.

SECTION 1.3. Interpretation. In this Agreement and each other Loan Document, unless a clear contrary intention explicitly appears:

(a) the singular number includes the plural number and vice versa;

(b) reference to any Person includes such Person’s successors and assigns but, if applicable, only if such successors and assigns are permitted by this Agreement, and reference to a Person in a particular capacity excludes such Person in any other capacity or individually;

(d) unless explicitly provided otherwise herein, reference to any agreement (including this Agreement and the Schedules and Exhibits hereto), document or instrument means such agreement, document or instrument as amended, restated, supplemented or modified and in effect from time to time in accordance with the terms thereof and, if applicable, the terms hereof and reference to any promissory note includes any promissory note which is an extension or renewal thereof or a substitute or replacement therefor;

ARTICLE II.

AMOUNT AND TERM OF COMMITMENTS

SECTION 2.1. Commitments. The Lenders shall make Loans to or for the benefit of the Borrower in accordance with their respective Revolving Commitments as provided below in this Section 2.1.

SECTION 2.1.1. Revolving Commitment. On the terms and subject to the conditions of this Agreement (including Article IV), each Lender severally and for itself alone agrees to make Loans to, and to issue or participate in the issuance of Letters of Credit and Swing Line Loans for the account of, the Borrower pursuant to its Revolving Commitment, as described in this Article II and in Article III, respectively. From time to time on any Business Day occurring prior to the Revolving Commitment Termination Date, each Lender, severally and for itself alone, agrees to make revolving loans in Dollars or in one or more Alternative Currencies (relative to such Lender, its “Revolving Loans”) to the Borrower equal to such Lender’s Revolving Credit Percentage of the aggregate amount of the applicable Borrowing requested by the Borrower to be made on such day pursuant to this Section 2.1.1. The commitment of each Lender described in this Section 2.1.1 is herein referred to as its “Revolving Commitment” and shall be in the amount set forth on the Commitment Schedule as such Lender’s “Revolving Commitment”; provided, however that (a) the aggregate Dollar Equivalent of all Loans which any Lender shall be committed to have outstanding hereunder shall not at any time exceed the product of (i) such Lender’s Revolving Credit Percentage multiplied by the Revolving Loan Availability, (b) the aggregate Dollar Equivalent amount of all Revolving Loans which the Lenders shall be committed to have outstanding hereunder shall not at any time exceed the Revolving Loan Availability and (c) the Dollar Equivalent amount of all Revolving Loans denominated in Alternative Currencies shall not exceed the Alternative Currency Sublimit.

SECTION 2.1.2. Swing Line Facility.

(a) Subject to the terms and conditions hereof, the Swing Line Lender may, in its sole discretion, make available from time to time until the Revolving Commitment Termination Date swing line loans in Dollars (each, a “Swing Line Loan”). The aggregate amount of Swing Line Loans outstanding shall not exceed at any time Swing Line Availability. Notwithstanding anything herein to the contrary, the aggregate outstanding principal balance of the Swing Line Loans may exceed the Swing Line Lender’s Revolving Credit Percentage of the Revolving Commitment Amount. Until the Revolving Commitment Termination Date, the Borrower may from time to time borrow, repay and reborrow Swing Line Loans under this Section 2.1.2. Each Swing Line Loan shall be made pursuant to a Notice of Borrowing delivered by the Borrower to the Administrative Agent in accordance with Section 2.4. Unless the Swing Line Lender has received at least one Business Day’s prior written notice from the Majority Lenders instructing it not to make a Swing Line Loan, the Swing Line Lender shall, notwithstanding the failure of any condition precedent set forth in Section 4.2, be entitled to fund such Swing Line Loan, and to have such Lenders make Revolving Loans in accordance with Section 2.1.2(c) or purchase participating interests in such Swing Line Loan in accordance with Section 2.1.2(d). Notwithstanding any other provision of this Agreement or the other Loan Documents, each Swing Line Loan shall constitute a Base Rate Loan. The Borrower shall repay the aggregate outstanding principal amount of each Swing Line Loan upon demand therefor by the Administrative Agent.

(b) The entire unpaid balance of each Swing Line Loan and all other Obligations shall be immediately due and payable in full in immediately available funds on the Revolving Commitment Termination Date if not sooner paid in full.

(c) The Swing Line Lender, at any time and from time to time no less frequently than once weekly, shall on behalf of the Borrower (and the Borrower hereby irrevocably authorizes the Swing Line Lender to so act on its behalf) request each Lender with a Revolving Commitment (including the Swing Line Lender) to make a Revolving Loan to the Borrower (which shall be a Base Rate Loan) in an amount equal to that Lender’s Revolving Credit Percentage of the principal amount of all Swing Line Loans (the “Refunded Swing Line Loan”) outstanding on the date such notice is given. Unless any of the events described in Section 7.1(e) has occurred (in which event the procedures of Section 2.1.2(d) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of a Revolving Loan are then satisfied, each Lender shall disburse directly to the Administrative Agent, its Revolving Credit Percentage on behalf of the Swing Line Lender, prior to 2:00 P.M., Chicago time, in immediately available funds on the date that notice is given (provided that such notice is given by 12:00 p.m., Chicago time, on such date). The proceeds of those Revolving Loans shall be immediately paid to the Swing Line Lender and applied to repay the Refunded Swing Line Loan.

(d) If, prior to refunding a Swing Line Loan with a Revolving Loan pursuant to Section 2.1.2(c), one of the events described in Section 7.1(e) has occurred, then, subject to the provisions of Section 2.1.2(e) below, each Lender shall, on the date such Revolving Loan was to have been made for the benefit of the Borrower, purchase from the Swing Line Lender an undivided participation interest in the Swing Line Loan in an amount equal to its Revolving

Credit Percentage of such Swing Line Loan. Upon request, each Lender shall promptly transfer to the Swing Line Lender, in immediately available funds, the amount of its participation interest.

(e) Each Lender’s obligation to make Revolving Loans in accordance with Section 2.1.2(c) and to purchase participation interests in accordance with Section 2.1.2(d) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such Lender may have against the Swing Line Lender, any Loan Party or any other Person for any reason whatsoever; (ii) the occurrence or continuance of any Default or Event of Default; (iii) any inability of the Borrower to satisfy the conditions precedent to borrowing set forth in this Agreement at any time or (iv) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If and to the extent any Lender shall not have made available to the Administrative Agent or the Swing Line Lender, as applicable, by 2:00 P.M., Chicago time, the amount required pursuant to Sections 2.1.2(c) or 2.1.2(d), as the case may be, on the Business Day on which such Lender receives notice from the Administrative Agent of such payment or disbursement (it being understood that any such notice received after noon, Chicago time, on any Business Day shall be deemed to have been received on the next following Business Day), such Lender agrees to pay interest on such amount to the Administrative Agent for the Swing Line Lender’s account forthwith on demand, for each day from the date such amount was to have been delivered to the Administrative Agent to the date such amount is paid, at a rate per annum equal to (a) for the first three days after demand, the Federal Funds Rate from time to time in effect and (b) thereafter, the Base Rate from time to time in effect.

SECTION 2.2. Reduction of Revolving Commitment Amount. The Borrower shall have the right, upon not less than two Business Days’ notice to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the aggregate amount of the Revolving Commitments; provided that no such termination or reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the total Revolving Extensions of Credit would exceed the Revolving Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a multiple of $500,000 in excess thereof, and shall reduce permanently the Revolving Commitments then in effect.

SECTION 2.3. Various Types of Loans. Each Loan shall be either a Base Rate Loan or a Eurodollar Rate Loan (each a “type” of Loan), as the Borrower shall specify in the related Notice of Borrowing or Continuation/Conversion Notice pursuant to Section 2.4 or 2.6; provided, however, that the Borrower may not request or have outstanding Eurodollar Rate Loans having more than eight (8) different Interest Periods.

SECTION 2.4. Borrowing Procedures. (a) The Borrower shall give notice to the Administrative Agent of each proposed Borrowing not later than (i) in the case of a Borrowing of Revolving Loans denominated in Dollars that are Base Rate Loans, 11:00 A.M. (Chicago time) on the proposed date of such Borrowing, (ii) in the case of a Borrowing of a Swing Line Loan, 2:00 (Chicago time) on the proposed date of such Borrowing, (iii) in the case of a Borrowing of Revolving Loans that are Eurodollar Rate Loans that are denominated in Dollars, 11:00 A.M. (Chicago time) at least two (2) Business Days prior to the proposed date of such Borrowing and

(iv) in the case of a Borrowing of Revolving Loans that are Eurodollar Rate Loans that are denominated in an Alternative Currency, 11:00 A.M. (Chicago time) at least four (4) Business Days prior to the proposed date of such Borrowing. Each such notice (a “Notice of Borrowing”) shall be requested by telephone with same day written confirmation by facsimile transmission, substantially in the form of Exhibit B hereto, specifying therein the date, the amount and type of such Borrowing and, in the case of a Borrowing of Eurodollar Rate Loans, the initial Interest Period therefor. Promptly following receipt of any such notice, the Administrative Agent shall advise each Lender thereof. All Loans requested on the Closing Date shall be Base Rate Loans.

(b) Except in the case of a Swing Line Loan, each Lender receiving such notice in a prompt manner (as described in clause (a) above) shall, before 2:00 P.M. (Chicago time) on the date of each proposed Borrowing, make available for the account of its Applicable Lending Office at the principal office of the Administrative Agent in same day funds in Dollars or the applicable Alternative Currency, as applicable, such Lender’s Revolving Credit Percentage of such Borrowing. Subject to Section 2.4(f), after the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article IV, the Administrative Agent will make such funds available to the Borrower to such account as the Borrower shall designate from time to time.

(c) Any Lender which does not make funds available at the applicable time specified under this Section 2.4 (any such Lender a “Defaulting Lender”) shall pay to the Administrative Agent on demand interest thereon at the Federal Funds Rate for the number of days from the date of the applicable Borrowing to the date on which such amount becomes immediately available to the Administrative Agent, together with such other compensatory amounts as may be required to be paid by such Lender to the Administrative Agent pursuant to the Rules for Interbank Compensation of the Council on International Banking or the Clearinghouse Compensation Committee, as the case may be, as in effect from time to time. A statement of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 2.4 shall be conclusive in the absence of manifest error. If such amount is not in fact made available to the Administrative Agent by such Lender on the same Business Day as the date of such Borrowing, the Administrative Agent shall be entitled to recover such amount from the Borrower (net of any amount received from the Defaulting Lender pursuant to the provisions of the first sentence of this Section), with interest thereon at the rate then applicable to the Loans comprising such Borrowing, on demand, provided that such payment by the Borrower shall in no way limit or restrict its ability to hold such Lender liable for its failure to so fund.

(d) Each Borrowing shall be in an aggregate amount not less than $1,000,000, or an integral multiple of $500,000 in excess thereof.

(e) Each Notice of Borrowing (whether in writing or by telephone) shall be irrevocable and binding on the Borrower. The Borrower shall provide the Administrative Agent with documents reasonably satisfactory to the Administrative Agent indicating the names of those employees of the Borrower authorized by the Borrower to make telephonic requests for Loans and continuations and conversions thereof, and the Administrative Agent shall be entitled to rely upon such documentation until notified in writing by the Borrower of any change(s) in the names of the employees so authorized. The Administrative Agent shall be entitled, in the

absence of willful misconduct, bad faith or gross negligence, to act on the instructions of anyone identifying himself as one of the persons authorized to request Loans and continuations and conversions thereof by telephone and the Borrower shall be bound thereby in the same manner as if the Person were actually so authorized. The Borrower agrees to indemnify and hold the Administrative Agent and each Lender harmless from any and all claims, damages, liabilities, losses, and reasonable out-of-pocket costs and expenses (including Attorney Costs and excluding loss of anticipated profits) which may arise or be created by the acceptance of instructions for making, continuing or converting any Loans by telephone, in the absence of willful misconduct, bad faith or gross negligence. In the case of any request for a Borrowing of Eurodollar Rate Loans, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure (i) to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article IV or (ii) to otherwise make the Borrowing in accordance with such Notice of Borrowing, including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Loan to be made by such Lender as part of such Borrowing when such Loan, as a result of such failure, is not made on such date.

(f) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Revolving Credit Percentage of such Borrowing, the Administrative Agent may assume that such Lender has made such Revolving Credit Percentage available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.4(b) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have made such Revolving Credit Percentage available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon (net of any amounts received from such Defaulting Lender in respect of such Defaulting Lender’s Revolving Credit Percentage of such Borrowing), for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Loans as part of such Borrowing for purposes of this Agreement.

(g) The failure of any Lender to make the Loans to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing.

SECTION 2.5. Evidence of Loans. The Loans made by each Lender shall, if requested by such Lender, be evidenced by the Notes payable to such Lender. All Loans and payments hereunder shall be recorded on the books of the Lender making such Loan or receiving such payment, which shall be rebuttable presumptive evidence of the amount of such Loans outstanding at any time hereunder. Notwithstanding any term or condition of this Agreement to the contrary, however, the failure of any Lender to record the date and amount of any Loan made

by such Lender hereunder or error in so recording shall not limit or otherwise affect the obligations of the Borrower to repay any such Loan and interest thereon; provided that if there is an error in so recording there shall be a rebuttable presumption that the records of the Administrative Agent are true and correct as to the amount of the Loan.

SECTION 2.6. Continuation/Conversion Procedures. Subject to Sections 2.3 and 2.4, the Borrower may convert any outstanding Loans (other than Swing Line Loans) of one type into Loans of another type or continue any outstanding Eurodollar Rate Loan as a Eurodollar Rate Loan, in each case by giving notice thereof to the Administrative Agent not later than 11:00 A.M. (Chicago time), (a) in the case of a conversion of a Eurodollar Rate Loan into a Base Rate Loan, on or before the proposed date of such conversion and (b) in the case of a continuation of a Eurodollar Rate Loan as, or a conversion of a Base Rate Loan into, a Eurodollar Rate Loan, at least two (2) Business Days prior to the proposed date of such continuation or conversion; provided, that Eurodollar Rate Loans may be continued or converted only as of the last day of the Interest Period applicable thereto (unless all payments which are due, if any, under Section 2.11 are made in connection with such continuation or conversion). Each such notice (a Continuation/Conversion Notice”) shall be by telephone with same day written confirmation by facsimile transmission substantially in the form of Exhibit C, specifying therein the date and amount of such continuation or conversion, the type of the Loan to be so converted or continued, and, in the case of a continuation of or conversion into a Eurodollar Rate Loan, the new Interest Period therefor. Promptly upon receipt of such notice (which shall be effective upon receipt by the Administrative Agent), the Administrative Agent shall advise each Lender thereof. Subject to Sections 2.18 and 2.19, such Loan shall be so converted or continued on the requested date of conversion or continuation; provided that each conversion or continuation shall be on a Business Day and, after giving effect to any such conversion or continuation, the aggregate principal amount of each outstanding Eurodollar Rate Loan shall be at least $1,000,000 and an integral multiple of $500,000. Each Eurodollar Rate Loan shall automatically convert to a Base Rate Loan at the end of the Interest Period applicable thereto, unless (i) in the case of an expiring Eurodollar Rate Loan, the Borrower shall have delivered to the Administrative Agent a Continuation/Conversion Notice not less than two (2) nor more than ten (10) Business Days prior to the last day of the Interest Period applicable thereto, and (ii) all of the other conditions contained in this Section 2.6 are satisfied; provided, however, that, in the case of a failure to timely request a continuation of Revolving Loans denominated in an Alternative Currency, such Revolving Loans shall be continued as Eurodollar Rate Loans in their original currency with an Interest Period of one month.

SECTION 2.7. Pro Rata Treatment. All Borrowings, continuations, conversions, prepayments, repayments and mandatory and voluntary Revolving Commitment Amount reductions shall be effected so that after giving effect thereto each Lender will have a ratable share (according to its Revolving Credit Percentage) of all Loans and Letters of Credit and of the Revolving Commitment Amount.

SECTION 2.8. Principal Payments. Repayments and prepayments of principal of the Loans shall be made in accordance with this Section 2.8.

SECTION 2.8.1. Repayments and Prepayments.

The Borrower will make payment in full in Dollars or the applicable Alternative Currency of all unpaid principal of all Loans and all other principal Obligations which are then outstanding on the Revolving Commitment Termination Date. Without limiting the foregoing, and in addition thereto, the Borrower:

(a) may, from time to time on any Business Day, make a voluntary prepayment, in whole or in part, of the outstanding principal amount of any Loans; provided that:

(i) any such prepayment of a Eurodollar Rate Loan prior to the last day of the Interest Period for such Loan shall be subject to Section 2.11,

(ii) no such prepayment of a Eurodollar Rate Loan may be made which, after giving effect thereto, would result in the aggregate outstanding principal amount of any remaining Eurodollar Rate Loans to be equal to an amount other than $1,000,000 or an integral multiple of $500,000 in excess thereof,

(iii) each such voluntary prepayment shall require written notice by 11:00 A.M. (Chicago time) on such Business Day but no more than five (5) Business Days prior to such prepayment, and

(iv) each such voluntary prepayment shall be in a minimum amount of $1,000,000 and an integral multiple of $500,000 in excess thereof (or, if less, the aggregate principal amount of all Loans outstanding);

(b) shall, unless the Majority Lenders and the Borrower shall otherwise agree, and subject to the Intercreditor Agreement, upon the consummation of any Disposition of any property of the Borrower or any of its Subsidiaries (excluding Dispositions permitted under Section 6.2(g) (other than any Permitted Dispositions to the extent a prepayment is required pursuant to the clause (c)(iii)(B) of the definition of “Permitted Disposition” set forth herein)) or Recovery Event, unless a Reinvestment Notice shall be delivered in respect thereof, make a mandatory prepayment of the Loans in an amount equal to the Net Cash Proceeds with respect to such transaction within three (3) Business Days of the receipt by the Borrower or any of its Subsidiaries of the Net Cash Proceeds (provided that the Borrower shall promptly provide notice to the Administrative Agent of the receipt of such Net Cash Proceeds) of such Disposition or Recovery Event; provided, however, that, notwithstanding the foregoing, (i) the aggregate Net Cash Proceeds of any Recovery Events that may be excluded from the foregoing application requirement pursuant to a Reinvestment Notice shall not exceed $15,000,000 in any Fiscal Year of the Borrower and (ii) on each Reinvestment Prepayment Date Revolving Loans shall be prepaid by an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event, as set forth above. The provisions of this Section do not constitute a consent to the consummation of any transaction not permitted by this Agreement;

(c) shall, at any time that the Revolving Extensions of Credit at such time exceed an amount equal to 105% of the Revolving Commitment Amount then in effect, then, within two Business Days after receipt of notice from the Administrative Agent, the Borrower shall prepay Loans and/or the Borrower shall Cash Collateralize the Letter of Credit Obligations in an aggregate amount sufficient to reduce such Revolving Extensions of Credit as of such date

of payment to an amount not to exceed 100% of the Revolving Commitment Amount then in effect;

(d) shall, at any time that the Letter of Credit Obligations in respect of all Letters of Credit exceeds an amount equal to 105% of the Letter of Credit Sublimit then in effect, then, within two Business Days after receipt of notice from the Administrative Agent, the Borrower shall Cash Collateralize the Letter of Credit Obligations in an aggregate amount sufficient to reduce such Letter of Credit Obligations as of such date of payment to an amount not to exceed 100% of the Letter of Credit Sublimit then in effect;

(e) shall, at any time that the Letter of Credit Obligations in respect of all Financial Letters of Credit exceeds an amount equal to 105% of the Financial Letter of Credit Sublimit then in effect, then, within two Business Days after receipt of notice from the Administrative Agent, the Borrower shall Cash Collateralize the Letter of Credit Obligations in respect of Financial Letters of Credit in an aggregate amount sufficient to reduce such Letter of Credit Obligations in respect of Financial Letters of Credit as of such date of payment to an amount not to exceed 100% of the Financial Letter of Credit Sublimit then in effect;

(f) shall, at any time that the Dollar Equivalent amount of all Revolving Loans denominated in Alternative Currencies exceeds an amount equal to 105% of the Alternative Currency Sublimit then in effect, then, within two Business Days after receipt of notice from the Administrative Agent, the Borrower shall prepay such Revolving Loans in an aggregate amount sufficient to reduce such the Dollar Equivalent Amount of Revolving Loans as of such date of payment to an amount not to exceed 100% of the Alternative Currency Sublimit then in effect;

(g) shall, immediately upon any acceleration of the maturity of any Loans pursuant to Section 7.2, repay all Loans; and

(h) each repayment and prepayment of any Loans made pursuant to this Section 2.8.1 shall be without premium or penalty, except as may be required by Section 2.11, and shall be applied in accordance with Section 2.8.2. Other than any mandatory prepayment of principal of the Loans in accordance with Section 2.8.1(b) and as provided in Sections 2.2 and 7.2, no mandatory or voluntary prepayment of principal of the Loans shall cause a permanent reduction in the Revolving Commitment Amount. Each mandatory prepayment of principal of the Loans in accordance with Section 2.8.1(b) shall result in a permanent reduction in the Revolving Commitment Amount in an amount equal to such mandatory prepayment. Each such permanent reduction in the Revolving Commitment Amount shall be allocated among the Lenders in accordance with their respective Revolving Credit Percentage. Prior to the occurrence of a Default, at the Borrower’s option, the Administrative Agent shall hold all mandatory prepayments made pursuant to Section 2.8.1(c) or (f) in escrow in an account for the benefit of the Lenders and shall release such amounts upon the expiration of the Interest Periods applicable to any Revolving Loans being prepaid (it being understood that interest shall continue to accrue on such Revolving Loans until such time as such prepayments are released from escrow and applied to reduce such Revolving Loans).

SECTION 2.8.2. Application. Amounts to be applied in connection with the voluntary and mandatory prepayments paid pursuant to the provisions of Section 2.8.1 (other than, for the avoidance of doubt, any Cash Collateral) shall be applied to the repayment of any outstanding Loans (without any permanent reduction to the Revolving Commitments other than pursuant to Sections 2.8.1(b), 2.2 and 7.2).

SECTION 2.9. Interest Payments. Interest on all Loans shall accrue and be payable in accordance with this Section 2.9.

SECTION 2.9.1. Rates. From the date any Loan is made to the date the principal amount of such Loan is repaid in full, interest shall accrue on the outstanding principal amount of such Loan at a rate per annum:

(a) on that portion of the outstanding principal amount thereof maintained from time to time as a Base Rate Loan (including, without limitation, any Swing Line Loans) equal to the Base Rate from time to time in effect, plus, the then Applicable Base Rate Margin; and

(b) on that portion of the outstanding principal amount thereof maintained from time to time as a Eurodollar Rate Loan, during each Interest Period applicable thereto, equal to the sum of the LIBOR Rate for such Interest Period, plus the then Applicable Eurodollar Rate Margin.

SECTION 2.9.2. Default Rate. If all or a portion of the principal amount of any Loan or Reimbursement Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), all outstanding Loans and Reimbursement Obligations (whether or not overdue) (to the extent legally permitted) shall bear interest at a rate per annum that is equal to (x) in the case of the Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% or (y) in the case of Reimbursement Obligations, the rate applicable to Base Rate Loans plus 2% (the “Default Rate”). If all or a portion of any interest payable on any Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the Default Rate.

SECTION 2.9.3. Payment Dates. Interest accrued on each Loan shall be payable, without duplication:

(a) with respect to any Loans, on the Revolving Commitment Termination Date;

(b) in the case of any Loan:

(i) on that portion of the outstanding principal amount thereof maintained as a Base Rate Loan, on the last day of each Fiscal Quarter, commencing with the first such day following the Closing Date; and

(ii) on that portion of the outstanding principal amount thereof maintained as a Eurodollar Rate Loan, on the last day of each applicable Interest Period and, if such Interest Period shall exceed three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period (or, if there is no numerically corresponding day in such subsequent month or if such numerically corresponding day is not a Business Day, on the next preceding Business Day); and

(c) on that portion of any Loans the maturity of which is accelerated pursuant to Section 7.2, immediately upon such acceleration.

Interest accrued on the principal amount of each Loan or other monetary Obligation arising under this Agreement or any other Loan Document after the date such amount is due and payable (whether on the Revolving Commitment Termination Date, upon acceleration or otherwise) shall be payable upon demand.

SECTION 2.9.4. Rate Determinations.

(a) All determinations by the Administrative Agent of any rate of interest applicable to any Loan or other monetary Obligation shall be presumptive evidence of such rate.

(b) If the Administrative Agent shall have determined that for any reason adequate and reasonable means do not exist for ascertaining the LIBOR Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or that the LIBOR Rate applicable pursuant to Section 2.9.1 for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such Loan, the Administrative Agent will immediately give notice of such determination to the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or continue Eurodollar Rate Loans hereunder, or permit the conversion of Base Rate Loans into Eurodollar Rate Loans, shall be suspended until the Administrative Agent revokes such notice in writing promptly after determining that the circumstances relating to its determination that adequate and reasonable means do not exist for ascertaining the LIBOR Rate no longer exist and no new such circumstances have come into being. Upon receipt of such notice, the Borrower may revoke any Notice of Borrowing or Continuation/Conversion Notice then submitted by it; provided, however, that such revocation shall not cause the Borrower to be obligated to reimburse the Lenders for costs under Section 2.11 in connection with such revocation. If the Borrower does not revoke such notice, the Lenders shall make, convert or continue the Loans, as originally proposed by the Borrower, in the amount specified in the applicable notice submitted by the Borrower, but such Loans shall be made, converted or continued as Base Rate Loans.

(c) On the date on which the aggregate unpaid principal amount of Loans shall be reduced, by payment or prepayment or otherwise, to less than $1,000,000, such Loans shall, if they are Eurodollar Rate Loans, automatically convert into Base Rate Loans, and on and after such date the right of the Borrower to convert Base Rate Loans into Eurodollar Rate Loans shall terminate. The Borrower shall be obligated to reimburse the Lenders for costs incurred in connection with such automatic conversion in accordance with Section 2.11.

SECTION 2.10. Increased Costs and Reduction of Returns.

(a) If any Issuing Lender or any Lender shall determine that, due to either (i) the introduction of or any change (other than any change by way of imposition of or increase in reserve requirements included in the calculation of the LIBOR Rate) in or in the interpretation of any law or regulation occurring after the Closing Date (other than a change in tax law) or (ii) the compliance with any guideline or request (other than a guideline or request relating to taxes) issued after the Closing Date from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to (including a reduction in the sum receivable by) such Issuing Lender or such Lender of agreeing to make or making, funding, continuing or maintaining any of its Loans as, or converting (or its obligation to convert) any portion of the principal amount of any of its Loans into, Eurodollar Rate Loans, or issuing, maintaining or participating in any Letter of Credit, then the Borrower shall be liable for, and shall from time to time, within fifteen (15) days after written demand therefor by the Administrative Agent on behalf of such Issuing Lender or such Lender in the form of a certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower and the Administrative Agent by such Issuing Lender or such Lender which certificate shall be presumptive evidence of such amounts (which demand the Administrative Agent hereby agrees to deliver), immediately pay to the Administrative Agent for the account of such Issuing Lender or such Lender, from time to time as specified by such Issuing Lender or such Lender, additional amounts as are sufficient to compensate such Issuing Lender or such Lender for such increased cost (including such reduced amount).

(b) If any Issuing Lender or any Lender shall have determined that (i) the introduction after the Closing Date of any Capital Adequacy Regulation, (ii) any change after the Closing Date in any Capital Adequacy Regulation, (iii) any change after the Closing Date in the interpretation or administration of any Capital Adequacy Regulation by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or (iv) compliance by such Issuing Lender or such Lender (or its Applicable Lending Office) or any corporation controlling such Issuing Lender or such Lender, with any Capital Adequacy Regulation issued after the Closing Date, in any such case affects or would affect the amount of capital required or expected to be maintained by such Issuing Lender or such Lender or any corporation controlling such Issuing Lender or such Lender and (taking into consideration such Issuing Lender’s or such Lender’s or such corporation’s policies with respect to capital adequacy and such Issuing Lender’s or such Lender’s desired return on capital) determines that the amount of such capital is increased as a consequence of its commitment to issue, its issuance of or participation in any Letter of Credit or its Revolving Commitments, Loans, credits or obligations under this Agreement, then, within fifteen (15) days after written demand therefor by the Administrative Agent on behalf of such Issuing Lender or such Lender in the form of a certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower and the Administrative Agent by such Issuing Lender or such Lender which certificate shall be presumptive evidence of such amounts (which demand the Administrative Agent hereby agrees to deliver), the Borrower shall pay to the Administrative Agent for the account of such Issuing Lender or such Lender, from time to time as specified by such Issuing Lender or such Lender, additional amounts as are sufficient to compensate such Issuing Lender or such Lender or such corporation for such increase.

(c) Without limiting the generality of clauses (a) and (b) of this Section 2.10, in the event that any Issuing Lender, in compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) or any Capital Adequacy Regulation issued after the Closing Date, or as a result of any change after the Closing Date in the interpretation or administration of any such guideline or Capital Adequacy Regulation by any central bank or Governmental Authority charged with the interpretation or administration thereof, determines that a Performance Letter of Credit should have been characterized at the time of issuance thereof or should be recharacterized as a Financial Letter of Credit, then the Borrower shall be liable for, and shall from time to time, upon demand therefor by such Issuing Lender in the form of a certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower and the Administrative Agent by such Issuing Lender, which certificate shall be presumptive evidence of such amounts (with a copy to the Administrative Agent), within fifteen (15) days after written demand therefor by the Administrative Agent on behalf of such Issuing Lender (which demand the Administrative Agent hereby agrees to deliver), pay to the Administrative Agent, for the account of such Issuing Lender, from time to time as specified by such Issuing Lender, such additional amounts as are sufficient to cause such Issuing Lender to receive Letter of Credit Fees under Section 3.3(a) from the date of issuance or recharacterization, as the case may be.

(d) Each Issuing Lender and each Lender agree to notify the Borrower and the Administrative Agent in writing promptly of any circumstances that would cause the Borrower to pay additional amounts pursuant to this Section 2.10, provided that the failure to give such notice shall not affect the Borrower’s obligation to pay such additional amounts hereunder. Notwithstanding anything to the contrary in this Section 2.10, the Borrower shall have no obligation to pay any additional amounts under clause (a), (b) or (c) of this Section 2.10 unless the claiming Issuing Lender or Lender shall have made demand upon the Borrower for such additional amounts within six (6) months after the claiming Issuing Lender or Lender obtained knowledge of the circumstances that would cause the Borrower to pay such additional amounts; provided, however, that the foregoing limitation shall not apply to any such additional amounts arising out of the retroactive application of any law, regulation, rule guideline or directive within such six (6) month period. A Lender or Issuing Lender shall be deemed to have obtained knowledge of any circumstances that would cause the Borrower to pay such additional amounts if any rules with respect to such increase have been published in the Federal Register and such knowledge shall be deemed to have been obtained on the later of the date when such new rule (i) is published in the Federal Register and (ii) becomes effective. Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower in this Section 2.10 shall survive the payment of all other Obligations.

(e) If the Borrower is required to pay additional amounts to any Lender or the Administrative Agent pursuant to Section 2.10, then such Lender shall use its reasonable best efforts (consistent with legal and regulatory restrictions) to take such actions (including, if applicable, to change the jurisdiction of its Applicable Lending Office) so as to minimize any such additional payment by the Borrower which may thereafter accrue if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender.

SECTION 2.11. Funding Losses. In the event any Lender shall incur any loss or expense (including any loss or expense incurred by reason of the liquidation or reemployment of

deposits or other funds acquired by such Lender to make, continue or maintain any portion of the principal amount of any Loan as, or to convert any portion of the principal amount of any Loan into, a Eurodollar Rate Loan) as a result of:

(a) repayment or prepayment of the principal amount of any Eurodollar Rate Loans on a date other than the last day of the Interest Period applicable thereto, whether pursuant to Section 2.8 or otherwise, or the compulsory assignment of a Eurodollar Rate Loan of a Non-Consenting Lender pursuant to Section 9.1;

(b) any conversion of all or any portion of the outstanding principal amount of any Eurodollar Rate Loans to Base Rate Loans prior to the expiration of the Interest Period then applicable thereto;

(c) any Loans not being made as Eurodollar Rate Loans in accordance with the Notice of Borrowing therefor (except in the event of a revocation of a Notice of Borrowing pursuant to Section 2.9.4 (b)); or

(d) any Loans not being continued as, or converted into, Eurodollar Rate Loans in accordance with the Continuation/Conversion Notice given therefor, then, upon the request by the Administrative Agent on behalf of such Lender in the form of a certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower and the Administrative Agent by such Lender, which shall be presumptive evidence of such amounts (which request the Administrative Agent hereby agrees to deliver), the Borrower shall pay to the Administrative Agent for the account of such Lender such amount as will (in the reasonable determination of such Lender) reimburse such Lender for such loss or expense. Solely for purposes of calculating amounts payable by the Borrower to such Lenders under this Section 2.11, each Eurodollar Rate Loan made by a Lender (and each related reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded at the rate used in determining the LIBOR Rate for such Eurodollar Rate Loan by a matching deposit or other borrowing in the interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan is in fact so funded. Any claim by a Lender for reimbursement under this Section 2.11 shall be set forth in a certificate delivered by such Lender to the Borrower and the Administrative Agent showing in reasonable detail the basis for such calculation and shall be presumptive evidence of such amounts. The agreements and obligations of the Borrower in this Section 2.11 shall survive the payment of all other Obligations.

If the Borrower is required to pay additional amounts to any Lender or the Administrative Agent pursuant to Section 2.11, then such Lender shall use its reasonable best efforts (consistent with legal and regulatory restrictions) to take such actions (including, if applicable, to change the jurisdiction of its Applicable Lending Office) so as to minimize any such additional payment by the Borrower which may thereafter accrue if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender.

SECTION 2.12. Illegality.

(a) If any Lender shall determine that the introduction of any Applicable Law, or any change in any Applicable Law or in the interpretation or administration thereof, has made it unlawful, or that any central bank or other Governmental Authority has asserted that it is unlawful, for any Lender or its Applicable Lending Office to make Eurodollar Rate Loans, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, the obligation of that Lender to make, convert into or continue Eurodollar Rate Loans, shall be suspended until such Lender shall have notified the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist.

(b) If a Lender shall determine that it is unlawful to maintain any Eurodollar Rate Loan, the Borrower shall prepay in full all Eurodollar Rate Loans of that Lender then outstanding, together with interest accrued thereon, or convert such Eurodollar Rate Loans into Base Rate Loans, either on the last day of the Interest Period thereof if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, upon request therefor if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans until the last day of the Interest Period, together with any amounts required to be paid in connection therewith pursuant to Section 2.11.

(c) If the Borrower is required to prepay any Eurodollar Rate Loan immediately as provided in Section 2.12(b), then concurrently with such prepayment, the Borrower shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan.

(d) If the obligation of any Lender to make or maintain Eurodollar Rate Loans has been terminated, the Borrower may elect, by giving notice to such Lender through the Administrative Agent that all Loans which would otherwise be made by such Lender as Eurodollar Rate Loans shall instead be Base Rate Loans.

(e) Before giving any notice to the Administrative Agent pursuant to this Section 2.12, the affected Lender shall designate a different Eurodollar Office with respect to its Eurodollar Rate Loans if such designation will avoid the need for giving such notice or making such demand and will not, in the judgment of such Lender, be illegal or otherwise disadvantageous to such Lender.

(f) If the Borrower is required to pay additional amounts to any Lender or the Administrative Agent pursuant to Section 2.12, then such Lender shall use its reasonable best efforts (consistent with legal and regulatory restrictions) to take such actions (including, if applicable, to change the jurisdiction of its Applicable Lending Office) so as to minimize any such additional payment by the Borrower which may thereafter accrue if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender.

SECTION 2.13. Right of the Lenders to Fund through Other Offices. Each Lender may, if it so elects, fulfill its commitment as to any Eurodollar Rate Loan by causing a foreign branch or affiliate of such Lender to make such Loan; provided that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by such Lender and the obligation of the Borrower to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it, to the extent of such Loan, for the account of such branch or affiliate.

SECTION 2.14. Non-Use Fee and Fee Obligations Generally.

(a) Non-Use Fee. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, a Non-Use Fee (the “Non-Use Fee”) in an amount equal to the product of (i) the Applicable Non-Use Fee Percentage multiplied by (ii) the daily average amount by which the Revolving Commitment Amount exceeds the sum of the outstanding principal balance of the Revolving Loans plus the then Letter of Credit Obligations, for the period from the Closing Date until the Revolving Commitment Termination Date. The Non-Use Fee shall be payable quarterly in arrears on the last day of each Fiscal Quarter for the Fiscal Quarter then ended and on the Revolving Commitment Termination Date. Solely for purposes of calculating the Non-Use Fee under this Section 2.14(a), the equivalent in Dollars of the undrawn face amount of each Letter of Credit made in an Alternative Currency shall be determined on the date of issuance of such Letter of Credit and shall be redetermined as of the last Business Day of each calendar month thereafter during which such Letter of Credit remains outstanding, with no interim adjustments with respect to any fluctuations in the value of such Alternative Currency.

(b) Other Fees. The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates from time to time agreed to in writing by the Borrower and the Administrative Agent.

(c) Fee Obligations. The obligation of the Borrower to pay the fees described in this Section 2.14, and the Letter of Credit Fees described in Section 3.3, shall be in addition to, and not in lieu of, the obligation of the Borrower to pay interest and expenses and other amounts otherwise described in this Agreement. The fees described in this Section 2.14 shall be fully earned on the earlier of the date paid or accrued and shall be non-refundable. The Letter of Credit Fees and the fees described in this Section 2.14 shall bear interest, if not paid when due, at the Default Rate.

SECTION 2.15. Payments and Computations.

(a) Allocation. All payments by the Borrower pursuant to this Agreement or any other Loan Document, whether in respect of principal of or interest on Loans or other Obligations, shall be made by the Borrower in Dollars or in the applicable Alternative Currency no later than 1:00 P.M. (Chicago time) on the day when due to the Administrative Agent in same day funds. Without limiting the generality of the foregoing, the Administrative Agent may require that any payments due under this Agreement be made in the United States. If, for any reason, the Borrower is prohibited by any Applicable Law from making any required payment hereunder in an Alternative Currency, the Borrower shall make such payment in Dollars in the Dollar Equivalent of the Alternative Currency payment amount. All payments in respect of principal of or interest on Loans or Letter of Credit Obligations shall (unless otherwise specified herein) be made by the Borrower to the Administrative Agent for the account of the Lenders pro rata according to the respective unpaid principal amounts of the Loans made by them or to their respective participation or other interests in such Letter of Credit Obligations, as the case may be. The payment of all fees referred to in Section 2.14 and Section 3.3 shall (unless otherwise specified therein) be made by the Borrower to the Administrative Agent for the account of the Lenders entitled thereto. All other amounts payable to the Administrative Agent or any Lender under this Agreement or any other Loan Document shall be paid to the Administrative Agent for

the account of the Person entitled thereto. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 9.7(d), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. The Administrative Agent shall promptly remit to each Lender in immediately available funds and in Dollars such Lender’s share of all such payments received by the Administrative Agent for the account of such Lender.

(b) All computations of interest or fees hereunder or under any other Loan Document shall be made by the Administrative Agent on the basis of a year of 360 days, except that, with respect to Base Rate Loans, the interest thereon shall be calculated on the basis of a year of 365 or 366 days, as the case may be, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

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

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

(e) All payments of principal, interest, fees and all expenses and other amounts due hereunder or under any other Loan Document payable to the Lenders shall be made without condition and in same day funds and delivered to the Administrative Agent on the date thereof not later than the applicable cut-off time described in Section 2.15(a), and funds received by the Administrative Agent after that time shall be deemed to have been paid on the next succeeding Business Day.

(f) Each payment of principal shall be applied to such Loans as the Borrower shall direct by notice received by the Administrative Agent on or before the date of such payment or, in the absence of such notice, first, to the unpaid principal amount of any

outstanding Base Rate Loans, second, to the unpaid principal amount of any outstanding Eurodollar Rate Loans with those Eurodollar Rate Loans which have earlier expiring Interest Periods being repaid prior to those which have later expiring Interest Periods, and then as the Administrative Agent shall determine in its discretion. Concurrently with each remittance to any Lender of its share of any such payment, the Administrative Agent shall advise such Lender as to the application of such payment.

SECTION 2.16. Taxes.

(a) Subject to Section 2.16(d), any and all payments by the Borrower to each Lender or the Administrative Agent under this Agreement shall be made free and clear of, and without, unless required by Applicable Law (in which case Section 2.16(d) shall apply), deduction or withholding for, any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and the Administrative Agent, such taxes (including income taxes or franchise taxes) as are imposed on or measured by each Person’s net income (including branch profits taxes), and franchise taxes are imposed on it by the jurisdiction under the laws of which such Lender or the Administrative Agent, as the case may be, is organized or maintains any Applicable Lending Office or any political subdivision of the foregoing (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”).

(b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Documents other than amounts as are being contested in good faith (hereinafter referred to as “Other Taxes”).

(c) Subject to Section 2.16(g), the Borrower shall indemnify and hold harmless each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes paid by Lender or the Administrative Agent as a result of its Revolving Commitment, any Loans made by it hereunder, or otherwise in connection with its participation in this Agreement and any liability (including penalties, interest, additions to tax and expenses) arising therefrom or with respect thereto (other than liability resulting from the gross negligence, bad faith or willful misconduct of such Lender or the Administrative Agent), whether or not such Taxes or Other Taxes were correctly or legally asserted. Payment under this indemnification shall be made within thirty (30) days from the date Lender or the Administrative Agent makes written demand therefor in the form of a certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower and the Administrative Agent by such Lender, which shall be presumptive evidence of such amounts, which written demand shall be made no sooner than thirty (30) days prior to the date Lender intends to pay such Taxes or Other Taxes and no later than ninety (90) days after such payment.

(d) If the Borrower shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any sum payable hereunder to any Lender or the Administrative Agent, then, subject to Section 2.16(g):

(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.16) such Lender or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made;

(ii) the Borrower shall make such deductions; and

(iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(e) Within thirty (30) days after the date of any payment by the Borrower of Taxes or Other Taxes, the Borrower shall furnish to the Administrative Agent the original or a certified copy of a receipt evidencing payment thereof, or other evidence of payment reasonably satisfactory to the Administrative Agent.

(f) Each Lender other than a Lender which is (1) a U.S. person (within the meaning of IRC Section 7701(a)(30)) and (2) treated as a corporation for U.S. federal income tax purposes agrees that:

(i) it shall, no later than the Closing Date (or, in the case of a Lender which becomes a party hereto pursuant to Section 9.7 after the Closing Date, the date upon which Lender becomes a party hereto) deliver to the Borrower through the Administrative Agent two accurate and complete signed originals of IRS Form W-9, Form W-8BEN or W-8 ECI or any successor thereto, in each case (“Withholding Forms”) indicating that the Lender is on the date of delivery thereof exempt from United States withholding tax and entitled to receive payments under this Agreement free from withholding of United States Federal income tax;

(ii) if at any time the Lender makes any changes necessitating a new Withholding Form, it shall with reasonable promptness deliver to the Borrower through the Administrative Agent in replacement for, or in addition to, the forms previously delivered by it hereunder, two accurate and complete signed originals of Withholding Forms indicating that the Lender is on the date of delivery thereof exempt from United States withholding tax and entitled to receive all payments under this Agreement free from withholding of United States Federal income tax;

(iii) it shall, before or promptly after the occurrence of any event (including the passing of time but excluding any event mentioned in clause (ii) above) requiring a change in or renewal of the most recent Withholding Forms previously delivered by such Lender, deliver to the Borrower through the Administrative Agent two accurate and complete original signed copies of Withholding Forms in replacement for the forms previously delivered by the Lender; and

(iv) it shall, promptly upon the Borrower’s or the Administrative Agent’s reasonable request to that effect, deliver to the Borrower or the Administrative Agent (as the case may be) such other forms or similar documentation as may be required

from time to time by any applicable law, treaty, rule or regulation in order to establish such Lender’s tax status for withholding purposes.

(g) The Borrower will not be required to pay any amounts in respect of United States Federal income tax pursuant to Section 2.16(c) or Section 2.16(d) to any Lender for the account of any Applicable Lending Office of such Lender:

(i) if the obligation to pay such additional amounts would not have arisen but for a failure by such Lender to comply with its obligations under Section 2.16(f) in respect of such Applicable Lending Office;

(ii) if such Lender shall have delivered to the Borrower a Withholding Form in respect of such Applicable Lending Office pursuant to Section 2.16(f), and such Lender shall not at any time be entitled to exemption from deduction or withholding of United States Federal income tax in respect of payments by the Borrower hereunder for the account of such Applicable Lending Office for any reason other than a change in United States law or regulations or in the official interpretation of such law or regulations by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of law) after the date of delivery of such Withholding Form; or

(iii) if the Lender shall have delivered to the Borrower a Withholding Form in respect of such Applicable Lending Office pursuant to Section 2.16(f), and such Lender shall not at any time be entitled to exemption from deduction or withholding of United States Federal income tax in respect of payments by the Borrower hereunder for the account of such Applicable Lending Office for any reason other than a change in United States law or regulations or any applicable tax treaty or regulations or in the official interpretation of any such law, treaty or regulations by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of law) after the date of delivery of such Withholding Form.

(h) If the Borrower is required to pay additional amounts to any Lender or the Administrative Agent pursuant to Section 2.16(d), then such Lender shall use its reasonable best efforts (consistent with legal and regulatory restrictions) (including changing the jurisdiction of its Applicable Lending Office) so as to eliminate any such additional payment by the Borrower which may thereafter accrue if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender.

(i) If the Administrative Agent or any Lender determines that it has received a refund or direct credit in respect of and specifically associated with any Taxes or Other Taxes as to which it has been indemnified by the Borrower, or with respect to which the Borrower has paid additional amounts, it shall promptly notify the Borrower of such refund or direct credit and shall within 30 days from the date of receipt of such refund or benefit of such direct credit (including any interest paid or credited by the relevant Governmental Authority attributable to such refund or direct credit) to the Borrower but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower with respect to the Taxes or Other Taxes giving rise to such refund or direct credit net of all out-of-pocket expenses of such Person.

(j) Without prejudice to the survival of any other agreement of the Borrower, the Lenders and the Administrative Agent hereunder, the agreements and obligations of the Borrower, the Lenders and the Administrative Agent contained in this Section 2.16 shall survive the payment of all other Obligations.

SECTION 2.17. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise, but not including any payment made from an assigning Lender to an assignee Lender or a Lender to a Participant on account of an assignment of Loans or participation) on account of the Loans or the Letters of Credit (other than pursuant to Section 2.10, 2.11, 2.12(b), 2.16 or 3.3(b)) in excess of its ratable share of payments on account of such Loans and/or the Letters of Credit obtained by all the Lenders entitled thereto, such Lender shall forthwith purchase from the other Lenders notified of such payment such participations in such Loans and/or Letters of Credit made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase from each such Lender shall be rescinded and each such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (a) the amount of such Lender’s required repayment to (b) 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. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.17 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

SECTION 2.18. Warranty. Each Notice of Borrowing pursuant to Section 2.4 and the delivery of each Letter of Credit Request pursuant to Section 3.2, shall automatically constitute a warranty by the Borrower to the Administrative Agent and each Lender to the effect that on the date of such requested Borrowing or the issuance of the requested Letter of Credit, as the case may be, (a) the warranties contained in the Loan Documents (except to the extent changes in facts or conditions are expressly permitted or required hereunder or thereunder) shall be true and correct in all material respects as of such requested date as though made on the date thereof unless an earlier date is so specified in such representation and warranty and (b) no Event of Default or Default shall have then occurred and be continuing or will result therefrom.

SECTION 2.19. Conditions. Notwithstanding any other provision of this Agreement (other than as set forth in Section 3.4), (a) no Lender (including the Swing Line Lender) shall be obligated to make any Loan, (b) no Lender shall be obligated to convert into or permit the continuation at the end of the applicable Interest Period of any Eurodollar Rate Loan (other than any Eurodollar Rate Loan denominated in an Alternative Currency, in which case such Eurodollar Rate Loans may be continued as Eurodollar Rate Loans in their original currency with an Interest Period of one month), and (c) no Issuing Lender shall be obligated to issue any Letter of Credit if, in any such case, an Event of Default or Default exists or would result therefrom.

SECTION 2.20. All Obligations Secured. The Loans, the Reimbursement Obligations, and all other Obligations of the Borrower and each other Person to the Administrative Agent, any Issuing Lender, any Lender or any other Secured Party, shall be secured by the Administrative Agent’s Lien, for the benefit of the Secured Parties, on all of the Collateral and by all other Liens heretofore, now, or at any time or times hereafter granted by the Borrower or any other Person to the Administrative Agent, any Issuing Lender, any Lender or any other Secured Party to secure any Obligations. The Borrower agrees that all of the rights of the Secured Parties set forth in this Agreement shall apply to any modification, amendment or restatement of, or supplement to, this Agreement, any supplements or exhibits hereto, and the other Loan Documents, unless otherwise agreed in writing.

SECTION 2.21. Use of Proceeds. The Borrower shall use the proceeds of the Loans for (a) the working capital requirements and general corporate purposes of the Borrower and its Subsidiaries, (b) the refinancing of existing debt of the Loan Parties, (c) the payment of fees and expenses in connection with the consummation of the transactions contemplated by this Agreement and (d) the financing of Capital Expenditures, including the purchase of certain vessels and improvements thereto and related mobilization costs.

SECTION 2.22. Assignment of Commitments Under Certain Circumstances. In the event that the Administrative Agent shall have delivered a notice or certificate on behalf of any Lender pursuant to Section 2.10, 2.12 or 2.16, the Loan Parties shall be required to make additional payments to any Lender under Section 2.16, or any Lender shall become a Defaulting Lender, the Borrower shall have the right, at its own expense, upon notice to such Lender and Administrative Agent, not later than sixty (60) days following such Lender’s delivery of such notice or certificate, to require such Lender or Defaulting Lender to transfer and assign, without recourse or discount, in accordance with and subject to the restrictions contained in Section 9.7, all of its interests, rights and obligations under this Agreement (including, without limitation, its Revolving Commitments and its Revolving Credit Percentage of the Obligations) to one or more financial institutions chosen by the Borrower (and approved by the Administrative Agent and the Issuing Lender, which approval shall not be unreasonably withheld) which have agreed to so acquire and assume such interests, rights and obligations. A Lender shall not be required to make any such transfer and assignment unless all Obligations owing to such Lender, including, without limitation, those arising under Sections 2.10, 2.12 and 2.16, have been paid in full and such Lender shall have no further obligations with respect to its Revolving Commitments, and no Lender shall be required to make any such transfer and assignment if prior thereto the circumstances entitling the Borrower to require such a transfer and assignment cease to apply as a result of such Lender’s withdrawing its notice or certificate pursuant to Section 2.10, 2.12 or 2.16, as applicable.

SECTION 2.23. Increase in the Revolving Commitment Amount.

(a) Request for Increase. Provided there exists no Default, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may on one or more occasions, request an increase in the Revolving Commitments by an amount not exceeding $25,000,000 in the aggregate for all such increases (subject to a minimum amount of $10,000,000 for any individual increase). At the time of sending such notice, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each

Lender is requested to respond (which shall in no event be less than ten Business Days from the date of delivery of such notice to the Lenders).

(b) Lender Elections to Increase. Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Revolving Commitment and, if so, whether by an amount equal to, greater than, or less than its Revolving Credit Percentage of such requested increase. Any Lender not responding within such time period shall be deemed to have declined to increase its Revolving Commitment.

(c) Notification by Administrative Agent; Additional Lenders. The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent and the Issuing Lender (which approvals shall not be unreasonably withheld or delayed), the Arranger, in consultation with the Borrower, may also invite additional financial institutions to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel.

(d) Effective Date and Allocations. If the Revolving Commitments are increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such increase and the Increase Effective Date. Each of the parties hereto hereby agrees that, upon any Increase Effective Date, this Agreement and the Commitment Schedule shall be deemed amended to the extent (but only to the extent) necessary to reflect the increase to the Revolving Commitment Amount and the increases to the Revolving Commitments under this Section. Any such deemed amendment may be memorialized in writing by the Administrative Agent and the Borrower furnished to the other parties hereto.

(e) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate of the Borrower dated as of the Increase Effective Date signed by an Authorized Officer of the Borrower (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) certifying that, before and after giving effect to such increase, (A) the representations and warranties contained herein and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and (B) no Default exists. The Borrower shall prepay on a non-ratable basis any Loans outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 2.11) to the extent necessary to keep the outstanding Loans ratable with any revised Revolving Credit Percentages of the Revolving Commitments arising from any nonratable increase in the Revolving Commitments under this Section.

(f) Increase in the Letter of Credit Sublimit. On any Increase Effective Date, with the written consent of each Issuing Lender, the Letter of Credit Sublimit may be increased by an amount up to the amount of the increase in the Revolving Commitment Amount on such Increase Effective Date.

(g) Conflicting Provisions. This Section shall supersede any provisions in Sections 2.17 or 9.1 to the contrary.

ARTICLE III.

LETTERS OF CREDIT

SECTION 3.1. Commitment for Letters of Credit. Prior to the Closing Date, Bank of America, N.A., as “Issuing Lender” under the Existing Credit Agreement has issued the Existing L/Cs, which from and after the Closing Date, shall constitute Letters of Credit hereunder. Subject to the terms and conditions hereof, each Issuing Lender hereunder, in reliance on the agreements of the other Lenders, set forth in Section 3.4, agrees to issue letters of credit (the letters of credit issued on and after the Closing Date pursuant to this Section 3.1 together with the Existing L/Cs, the “Letters of Credit”) in Dollars or in Alternative Currencies for the account of the Borrower, and each Lender severally agrees to participate in the Letters of Credit (including Existing L/Cs) issued by each Issuing Lender hereunder, in a Dollar Equivalent amount equal to such Lender’s Revolving Credit Percentage, from time to time, on any Business Day during the period commencing on the date hereof, and continuing until the Revolving Commitment Termination Date in such form as may be approved from time to time by the applicable Issuing Lender; provided, that no Issuing Lender shall have any obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the Letter of Credit Obligations would exceed the Letter of Credit Availability, (ii) the Letter of Credit Obligations in respect of Financial Letters of Credit exceed the Financial Letter of Credit Availability or (iii) the aggregate amount of Available Revolving Commitments would be less than zero. Each Letter of Credit shall expire no later than the earlier of (x) the fourth anniversary of its date of issuance and (y) the date which is prior to the Revolving Commitment Termination Date as in effect at the time of the issuance of the Letter of Credit; provided that any Letter of Credit with a one-year term may provide for renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above).

SECTION 3.2. Issuance of Letters of Credit.

(a) The Borrower shall give the applicable Issuing Lender prior written notice (a “Letter of Credit Request”) not later than 11:00 A.M. (Chicago time) on the Business Day immediately preceding the date on which the issuance or amendment of a Letter of Credit is requested or, in the case of a requested Letter of Credit to be denominated in an Alternative Currency, on the Business Day immediately preceding the date on which the issuance or amendment of such a Letter of Credit is requested (or, in either case, such shorter time if consented to by the Administrative Agent and such Issuing Lender), specifying:

(i) the requested date for issuance or amendment of such Letter of Credit, which shall be a Business Day;

(ii) the expiry date of such Letter of Credit, which shall be a Business Day;

(iii) the beneficiary of such Letter of Credit;

(iv) the aggregate face amount of such Letter of Credit and the requested currency in which such Letter of Credit is to be denominated;

(v) whether the Letter of Credit to be issued is a Financial Letter of Credit or a Performance Letter of Credit; and

(vi) the conditions for drawing to be included in such Letter of Credit.

Each such Letter of Credit Request shall be by telecopier, telex or cable, confirmed immediately in writing by mail, in substantially the form of Exhibit D and executed by an Authorized Officer of the Borrower.

(b) Upon receipt of a Letter of Credit Request, the applicable Issuing Lender shall promptly send a copy thereof to the Administrative Agent who shall then notify each Lender of the contents thereof. Upon satisfaction of the conditions precedent specified in Article IV hereof, and subject to the provisions of Section 3.2(c), such Issuing Lender shall issue the Letter of Credit requested to be issued by it or amend the Letter of Credit requested to be amended, as the case may be, on the date specified in the Letter of Credit Request; provided that no Issuing Lender shall issue or maintain a Letter of Credit having an expiry date later than the date specified in Section 3.1. Promptly after the issuance by an Issuing Lender of a Letter of Credit, such Issuing Lender shall furnish a copy of such Letter of Credit to the Administrative Agent and the Borrower.

(c) In the case of a requested Letter of Credit to be denominated in an Alternative Currency, the obligation of the applicable Issuing Lender to issue such Letter of Credit is subject to the confirmation by such Issuing Lender to the Administrative Agent on the Business Day of the requested date of such issuance that such Issuing Lender agrees to issue such Letter of Credit in the requested Alternative Currency, which confirmation shall be promptly forwarded by the Administrative Agent to the Borrower. If such Issuing Lender shall not have so provided to the Administrative Agent such confirmation, the Administrative Agent shall promptly notify the Borrower that such Issuing Lender has not provided such confirmation, and the Borrower’s request for such Letter of Credit in such Alternative Currency shall be deemed to have been thereupon withdrawn by the Borrower.

SECTION 3.3. Letter of Credit Fee. The Borrower agrees to pay to the Administrative Agent (a) ratably for the account of each Lender, a letter of credit fee for the term of such Letter of Credit at the rate equal to the aggregate face amount outstanding of such Letter of Credit multiplied by (i) in the case of Performance Letters of Credit, subject to Section 2.10(c), the then Applicable Performance Letter of Credit Fee Percentage and (ii) in the case of Financial Letters of Credit, the then Applicable Financial Letter of Credit Fee Percentage, and (b) for the applicable Issuing Lender’s own account (in addition to its Revolving Credit Percentage of the fee payable to it as a Lender, in accordance with clause (a) above), a letter of credit fee for the term of such Letter of Credit of 0.125 of 1% per annum (or such lower amount if agreed to by the applicable Issuing Lender) based upon the aggregate face amount outstanding of each such Letter of Credit and the applicable Issuing Lender’s customary processing fees for the issuance, amendment or renewal of the Letter of Credit. The fee for any Letter of Credit issued by any Issuing Lender hereunder, as determined in accordance with clauses (a) and (b) above (the

“Letter of Credit Fee”), shall be payable quarterly in arrears on the last day of each Fiscal Quarter, on the Revolving Commitment Termination Date and on the earliest of the cancellation, expiration or return of such Letter of Credit to the applicable Issuing Lender; provided that if any Letter of Credit is canceled and/or returned to the applicable Issuing Lender prior to the expiration thereof, the Borrower shall from time to time, upon demand by such Issuing Lender and/or any Lender therefor, immediately pay to such Issuing Lender and/or such Lender additional amounts sufficient to compensate it for its expenses not covered by a previously received Letter of Credit Fee. A certificate as to the amount of such expenses submitted to the Borrower and the Administrative Agent by such Issuing Lender and/or such Lender, showing in reasonable detail the calculation thereof, shall be presumptive evidence of such amount.

SECTION 3.4. Obligations of the Lenders to an Issuing Lender under a Letter of Credit. Each Issuing Lender will notify the Borrower and the Administrative Agent, and the Administrative Agent will thereupon notify each other Lender, promptly upon presentation to it of a draft for payment drawn under, or purporting to be drawn under, a Letter of Credit issued by it; provided that the Administrative Agent and each Lender shall have received notice by 2:00 P.M. (Chicago time) on the Business Day on which such Issuing Lender intends to make payment of each such draft, to the extent that the Borrower fails to provide funds therefor, each other Lender shall make payment to the Administrative Agent, for the benefit of the applicable Issuing Lender in immediately available funds and in Dollars at the applicable Issuing Lender’s Domestic Lending Office of an amount equal to the Dollar Equivalent amount (as calculated by the applicable Issuing Lender) of such Issuing Lender’s payment multiplied by such other Lender’s Revolving Credit Percentage. The obligation of each Lender to make payments to the Administrative Agent for the benefit of each Issuing Lender under this Section 3.4 shall be unconditional, continuing, irrevocable and absolute regardless of whether or not any of the conditions set forth in Article IV are then satisfied. In the event that any Lender fails to make payment to the Administrative Agent for the benefit of any Issuing Lender of any amount due under this Section 3.4, such Issuing Lender shall be entitled to receive the principal and interest otherwise payable to such Lender hereunder with respect to such amount until such Issuing Lender receives such payment from such Lender; provided that nothing contained in this sentence shall relieve such Lender of its obligation to make payment to any Issuing Lender for such amounts in accordance with this Section 3.4.

SECTION 3.5. Reimbursement Obligation. The Borrower agrees unconditionally and irrevocably to pay to the Administrative Agent in Dollars and in immediately available funds for the account of the applicable Issuing Lender (and, to the extent such payments were made by the Lenders pursuant to Section 3.4, for the account of such Lenders), upon demand therefor by the Administrative Agent (which demand the Administrative Agent hereby agrees to deliver), the Dollar Equivalent amount of each payment which is drawn under a Letter of Credit, or which purports to be so drawn (such obligation of the Borrower being referred to herein as a “Reimbursement Obligation” with respect to such Letter of Credit). If at any time the Borrower fails immediately to repay a Reimbursement Obligation pursuant to this Section 3.5, the Borrower shall be deemed to have requested a Revolving Loan which is a Base Rate Loan, as of the date of the payment giving rise to the Reimbursement Obligation, from each Lender, equal in amount to such Lender’s Revolving Credit Percentage multiplied by the Dollar Equivalent amount of the unpaid Reimbursement Obligation, the proceeds of which shall be used to repay such Reimbursement Obligation. If, as a result of a Default or an Event of Default, a Revolving

Loan may not be made on a date on which such Loan would be deemed to have been requested pursuant to the preceding sentence, the unpaid Dollar Equivalent amount of the Reimbursement Obligation shall bear interest at the Default Rate and shall be payable on demand. Regardless of the expiration date of any Letter of Credit, the Borrower shall remain liable with respect to each Letter of Credit and all letter of credit fees shall continue to accrue, until the applicable Issuing Lender is released from liability by every Person which is entitled to draw or demand payment under such Letter of Credit.

SECTION 3.6. Representatives of Beneficiaries. Each Issuing Lender may receive, accept or pay as complying with the terms of such Letter of Credit, any drafts or other documents, otherwise in order, which may be signed by, or issued to, the administrator or executor of, or the trustee in bankruptcy of, or the receiver for any of the property of, the party in whose name such Letter of Credit provides that any drafts or other document should be drawn or issued.

SECTION 3.7. Responsibility of the Administrative Agent, the Issuing Lenders and the Lenders. None of the Administrative Agent, any Issuing Lender or any Lender shall be liable or responsible for:

(a) the use which may be made of the Letters of Credit or for any acts or omissions of the beneficiary(ies) in connection therewith;

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

(c) failure of any draft to bear any reference or adequate reference to a Letter of Credit, or failure of documents to accompany any draft at negotiation, or failure of any Person to surrender or to take up a Letter of Credit or to send forward documents, apart from drafts required by the terms of the relevant Letter of Credit, each of which provisions, if contained in such Letter of Credit itself, it is agreed may be waived by the applicable Issuing Lender;

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

(e) any other circumstances whatsoever in making or failing to make payment under a Letter of Credit;

except only that the Borrower shall have a claim against an Issuing Lender, and such Issuing Lender shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower which are determined to be caused by (i) such Issuing Lender’s willful misconduct, bad faith or gross negligence or (ii) such Issuing Lender’s willful or grossly negligent failure to pay under the relevant Letter of Credit after the presentation to such Issuing Lender by the relevant beneficiary of such Letter of Credit of a sight draft and certificate strictly complying with the terms and conditions of such Letter of Credit.

The happening of any one or more of the contingencies referred to in subparagraphs (a), (b), (c), (d) or (e) above shall not affect, impair or prevent the vesting of any of the rights or powers of the Issuing Lenders, the Lenders or the Administrative Agent hereunder. In furtherance and extension and not in limitation of the specific provisions hereinbefore set forth, it is hereby further agreed that any action, inaction or omission taken or suffered by the Administrative Agent, any Issuing Lender or any Lender, under or in connection with a Letter of Credit or the relative drafts, documents or assets, if in conformity with such foreign or domestic laws, customs or regulations as are applicable thereto and without willful misconduct, bad faith or gross negligence, shall be binding upon the Borrower and shall not place the Administrative Agent, any Issuing Lender or any Lender under any resulting liability to the Borrower. The word “assets” as used in this Section 3.7 includes goods and merchandise, as well as any and all documents relative thereto, securities, funds, choses in action, and any and all other forms of property, whether real, personal or mixed and any right or interest of the Borrower therein or thereto.

SECTION 3.9. Uniform Customs and Practice for Documentary Credits. Except as otherwise expressly provided in this Agreement or as the Borrower and the Lenders may otherwise expressly agree with regard to, and prior to the issuance of, a Letter of Credit, the “Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500,” as hereafter amended, revised, supplemented, or replaced by other publication of similar effect, shall in all respects be deemed a part hereof as fully as if incorporated herein and shall apply to such Letter of Credit.

SECTION 3.10. Indemnification. The Borrower hereby agrees to indemnify and hold harmless the Administrative Agent, each Issuing Lender and each Lender from and against any and all claims, damages, losses, liabilities, and reasonable out-of-pocket costs or expenses whatsoever (in each case, excluding loss of anticipated profits) which the Administrative Agent, an Issuing Lender or a Lender may incur (or which may be claimed against the Administrative Agent, an Issuing Lender or a Lender by any Person) by reason of or in connection with the execution and delivery or transfer of, or payment or failure to pay under, any Letter of Credit; provided that the Borrower shall not be required to indemnify any Issuing Lender for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by the willful misconduct, bad faith or gross negligence of such Issuing Lender, the Administrative Agent or any Lender. Nothing in this Section 3.10 is intended to limit the reimbursement obligation of the Borrower contained in Section 3.5 hereof.

SECTION 3.11. Transitional Provisions. The Borrower, Bank of America, N.A., as “Administrative Agent,” and the Existing Lenders are currently parties to the Existing Credit Agreement pursuant to which, among other things, Bank of America, N.A., as “Issuing Lender”

thereunder issued certain “Letters of Credit” (as defined therein) for the account of the Borrower (to the extent outstanding on the Closing Date and set forth on Schedule II, the “Existing L/C’s”). Each of the Existing L/C’s shall remain outstanding and constitute Letters of Credit issued by an Issuing Lender for the account of the Borrower pursuant to this Agreement on the Closing Date for all purposes under this Agreement and any other Loan Document, including, for the purpose of the accrual and payment of Letter of Credit Fees payable pursuant to Section 3.3 for the remaining term of such Existing L/C’s (other than for customary processing fees for the issuance, amendment or renewal of such Existing L/C’s occurring prior to the Closing Date or relating to the deemed issuance thereof occurring on the Closing Date). All “Reimbursement Obligations” and other “Letter of Credit Obligations” (as respectively defined in the Existing Credit Agreement) which remain outstanding on the Closing Date with respect to the Existing L/C’s shall constitute Reimbursement Obligations and Letter of Credit Obligations of the Borrower under this Agreement and shall be included in the calculations of Revolving Loan Availability, Letter of Credit Availability, Swing Line Availability and Financial Letter of Credit Availability. Schedule II sets forth, as of the date hereof, the aggregate outstanding face amount, identifying number, expiry date and name of the beneficiary, with respect to the Existing L/C’s.

SECTION 3.12. Supporting L/C Documents. The Borrower hereby agrees to execute and deliver to each Issuing Lender such letter of credit applications, master letter of credit agreements and other documents as such Issuing Lender may reasonably request in connection with the Letters of Credit issued by such Issuing Lender hereunder (each, a “Supporting L/C Document”). Notwithstanding anything to the contrary herein, to the extent that the terms of any Supporting L/C Document conflict with the terms of this Agreement, the terms of this Agreement shall govern.

(a) Organization; Corporate Powers. Each Loan Party (i) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization (except to the extent that such Loan Party’s failure to be in good standing under such laws could not reasonably be expected to have a Material Adverse Effect and except as otherwise as a result of a transaction permitted under Section 6.2(a)(i)), (ii) is duly qualified to do business as a foreign corporation and in good standing under the laws of each jurisdiction in which such qualification and good standing are necessary in order for it to conduct its business and own its property as heretofore conducted and owned (except such jurisdictions where failure to so qualify could not reasonably be expected to have a Material Adverse Effect), and (iii) has all requisite power to conduct its business, to own and operate its property and to execute, deliver and perform all of its obligations under the Loan Documents to which it is a party.

(b) Authorizations; Enforceability. Each Loan Party has the requisite authority to execute, deliver and perform each of the Loan Documents executed by it. Each of the Loan Documents to which any Loan Party is party has been duly executed and delivered by such Loan Party and constitutes the legal, valid and binding obligation of such Loan Party, enforceable against such Loan Party in accordance with its terms, subject to bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and to general principles of equity, regardless of whether enforcement is sought in a proceeding at law or in equity.

(c) No Conflict. The execution, delivery and/or performance by each Loan Party of each Loan Document to which it is a party do not and will not, by the lapse of time, the giving of notice or otherwise, (i) constitute a violation of any Applicable Law or a breach of any provision contained in such party’s charter or by-laws or other organizational documents or contained in any material agreement, instrument or document to which the Borrower or any of the Borrower’s Subsidiaries is a party or by which it is bound or (ii) result in or require the creation or imposition of any Lien whatsoever upon any of the properties or assets of Borrower or any of its Subsidiaries (other than Liens granted pursuant to the Collateral Documents).

(e) Licenses and Permits. Each of the Borrower and each of the Borrower’s Subsidiaries owns or possesses or is licensed or otherwise has the right to use all Permits and other governmental approvals and authorizations, franchises, authorizations and other rights that are reasonably necessary for the operations of its business as currently conducted, without, to the knowledge of Borrower or any of its Subsidiaries, conflict with the rights of any other Person with respect thereto, except where the failure to be so licensed or to have such Permits would not have a Material Adverse Effect.

As of the Closing Date, none of the Borrower or any of its Subsidiaries has incurred any loss contingencies or other contingent obligations since the respective dates of such financial statements which could reasonably be expected to have a Material Adverse Effect. The Borrower and the other Loan Parties, on a consolidated basis, are Solvent prior to, and on the date of each Borrowing or Issuance of a Letter of Credit, after giving effect to the consummation of the Transactions, including the Loans made, or to be made, and Letters of Credit issued, or to be issued, to the Borrower.

(t) Insurance. As of the Closing Date, Schedule 5.1(t) sets forth a complete and accurate list in all material respects of insurance policies and programs in effect with respect to the properties and businesses of the Borrower and each of the Borrower’s Subsidiaries, specifying for each such policy and program, (i) the amount thereof, (ii) the risks insured against thereby, (iii) the name of the insurer and each insured party thereunder and (iv) the policy or other identification number thereof.

(u) Collateral Documents. The provisions of the Collateral Documents executed by any Loan Party in favor of the Administrative Agent evidence legal, valid, enforceable and continuing Liens, in favor of the Administrative Agent for the benefit of the Secured Parties, in all right, title and interest of such Loan Party in any and all of the Collateral described therein, securing the Obligations from time to time outstanding, and upon all proper filings and recordings being duly made in the locations referred to in the applicable Collateral Documents or the taking of possession of the Collateral by the Administrative Agent in accordance with the provisions of such Collateral Documents, each of such Liens created pursuant to the Collateral Documents constitutes a fully perfected first or second priority Lien in all right, title and interest of such Loan Party in such Collateral superior in right to any Liens (other than the Liens of Travelers), existing or future, which such Loan Party or any creditors thereof or purchasers therefrom, or any other Person, may have against such Collateral or interests therein, except for Liens permitted by Section 6.2(h). Each Ship Mortgage on United States flag vessels will constitute as of the date and time of filing with the NVDC a preferred mortgage pursuant to § 31322(a) of Title 46 of the United States Code. Each Ship Mortgage on Republic of the Marshall Islands flag vessels will constitute as of the date and time of filing with the Maritime Administrator of the Republic of the Marshall Islands a preferred mortgage pursuant to the Republic of the Marshall Islands Preferred Ship Mortgage and Maritime Liens Act, codified at § 303 of the Republic of the Marshall Islands Maritime Act, 1990, as amended, and also pursuant to §31301(6)(B) of Title 46 of the United States Code.

(w) Accuracy of Information. The schedules, certificates and other written statements and information furnished to the Administrative Agent, the Issuing Lenders and the Lenders by or on behalf of any Loan Party in connection with the negotiation of this Agreement and the other Loan Documents do not contain any material misstatement of material fact or omit to state a material fact or any fact necessary to make the material statements contained therein not misleading in any material respect in light of the circumstances under which such information was provided as of the time when delivered. As of the Closing Date, there is no fact currently known to any Loan Party which now or in the future could reasonably be expected to have a Material Adverse Effect and which has not been set forth or referred to in this Agreement, the other Loan Documents, or such schedules, certificates, statements or information heretofore furnished to the Administrative Agent.

(x) Obligations and Guaranties “Senior Debt” under Note Indenture. The Obligations and the Guaranties constitute “Senior Debt” as defined in the Note Indenture.

(iii) The Borrower or any of its Subsidiaries defaults in the payment when due of any amount due under the Bonding Agreement or breaches or defaults with respect to any other term of the Bonding Agreement, if the effect of such failure to pay, default or breach is to cause any Person executing bonds, undertakings or instruments of guaranty as surety for the Borrower or any of its Subsidiaries to take possession of the work under any of the bonded contracts of the Borrower or any of its Subsidiaries and such possession could reasonably be expected to result in a Material Adverse Effect; or

SECTION 7.2. Acceleration. Upon the occurrence of any Event of Default described in clause (ii) or (iii) of Section 7.1(e), the Commitments shall each automatically and immediately terminate and all unpaid Obligations shall automatically become immediately due and payable, without presentment, demand, or protest or other requirements of any kind (including valuation and appraisement diligence, presentment, notice of intent to demand or accelerate and of acceleration), all of which are hereby expressly waived by the Borrower, and the obligation of each Lender to make any Loan and of the Issuing Lenders to issue and of the Lenders to participate in any Letter of Credit hereunder shall thereupon terminate; and upon the occurrence

and during the continuance of any other Event of Default, the Administrative Agent may, and at the direction of the Majority Lenders, shall, by written notice to the Borrower, immediately terminate the Commitments and/or declare all of the Obligations of the Borrower to be, and the same shall forthwith become, immediately due and payable together with accrued interest thereon, and the obligation of each Lender to make any Loan and of the Issuing Lenders to issue and of the Lenders to participate in any Letter of Credit hereunder shall thereupon terminate. In addition to and not in limitation of any other right available to the Lenders under any of the Loan Documents or otherwise at law or equity, upon the giving of such notice by the Administrative Agent, the Borrower shall be required to deposit immediately with the Administrative Agent for the benefit of the Lenders, in immediately available funds, an amount equal to the Letter of Credit Obligations (the “Deposit”). The Borrower’s obligation to pay the Deposit shall be absolute and unconditional, and the Deposit shall be deposited in a special collateral account with the Administrative Agent to ensure reimbursement of any drawings under such Letters of Credit and payment of all other amounts due and payable under any of the Loan Documents regarding the Letters of Credit.

SECTION 7.3. Injunctive Relief. The Borrower recognizes that in the event the Borrower fails to perform, observe or discharge any of its Obligations, any remedy of law may prove to be inadequate relief to the Administrative Agent or any Lender, therefore the Borrower agrees that the Administrative Agent and each Lender, if the Administrative Agent or such Lender so requests, shall be entitled to temporary and permanent injunctive relief during the continuation of an Event of Default in any such case without the necessity of proving actual damages or inadequacy of damages as an available remedy therefor.

SECTION 7.4. Allocation Among Secured Parties. Following the occurrence of an Event of Default, and notwithstanding anything in this Agreement to the contrary, all payments, and collections with respect to proceeds of Collateral and all other payments and other applications otherwise on account of any of the Obligations, shall be applied to the Obligations which are then due and payable and if such payments and proceeds are insufficient to satisfy all such Obligations which are due and payable, such payments and proceeds shall be applied in the following order in each case ratably among such Obligations: (i) to the payment of all amounts then due with respect to reasonable out-of-pocket fees (including Attorney Costs), charges, expenses and indemnity claims due the Administrative Agent, (ii) to the payment of all other amounts then due with respect to reasonable out-of-pocket fees (including Attorney Costs), charges, expenses and indemnity claims due the other Secured Parties, (iii) to the payment of amounts then due with respect to interest on the Loans, (iv) to the payment of amounts then due with respect to principal of the Loans and Reimbursement Obligations (and to the extent Letter of Credit Obligations are contingent, cash collateral with respect thereto), and amounts then due the Secured Parties with respect to Rate Protection Agreements and (v) to the payment of all other Obligations.

No Administrative Agent-Related Person shall be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions, of this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower or any of its Subsidiaries or Affiliates.

SECTION 8.4. Reliance by Administrative Agent.

(a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone 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 the Loan Parties), independent accountants and other experts selected by the Administrative Agent. Except for its express obligations set forth in Article II hereof, the Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders 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 Majority Lenders or such greater number of Lenders required by Section 9.1 and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Lenders.

(b) For purposes of determining compliance with the conditions specified in Sections 4.1 and 4.2, each Lender that has executed this Agreement, or an Assignment and Acceptance, shall be deemed to have consented to, approved or accepted or to be satisfied with each document or other matter either sent by the Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to such Lender, unless an officer of the Administrative Agent responsible for the transactions contemplated by the Loan Documents shall have received notice from such Lender prior to the initial Borrowing specifying its objection thereto and either such objection shall not have been withdrawn by notice to the Administrative Agent to that effect or such Lender shall not have made available to the Administrative Agent such Lender’s ratable portion of such Borrowing.

The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be requested by the Majority Lenders in accordance with Article VII; provided that unless and until the Administrative Agent shall have received any such request, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

SECTION 8.6. Credit Decision. Each Lender expressly acknowledges that none of the Administrative Agent-Related Persons has made any representation or warranty to it and that no act by the Administrative Agent hereinafter taken, including any review of the affairs of the Loan Parties shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent 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 all applicable bank regulatory laws relating to the transactions contemplated thereby, and made its own decision to enter into this Agreement and extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent 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 Borrower. Except for notices, reports and other documents expressly herein required to be furnished to the Lenders by the Administrative Agent, the Administrative Agent shall not 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 the Borrower which may come into the possession of any of the Administrative Agent-Related Persons.

SECTION 8.7. Indemnification. Whether or not the transactions contemplated hereby shall be consummated, the Lenders shall indemnify upon demand the Administrative Agent-Related Persons (to the extent not reimbursed by or on behalf of the Borrower and without limiting the obligation of the Borrower to do so), ratably according to such Lender’s Revolving Credit Percentage from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind whatsoever which may at any time (including at any time following the repayment of the Loans and the termination or resignation of the related Administrative Agent) be imposed on, incurred by or asserted against any such Person and which are in any way relating to or arising out of this Agreement or any document contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by any such Person under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment to the Administrative Agent-Related Persons of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from such Person’s gross negligence, bad faith or willful misconduct. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. Without limiting the generality of the foregoing, if the IRS or any other Governmental Authority of the United States or other jurisdiction asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason) such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including penalties and interest, and including any taxes imposed by any jurisdiction on the amounts payable to the Administrative Agent under this

Section, together with all costs and expenses (including Attorney Costs). The obligation of the Lenders in this Section shall survive the payment of all Obligations hereunder.

SECTION 8.8. Administrative Agent in Individual Capacity. LaSalle 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 or other business with the Loan Parties and their Affiliates as though LaSalle were not the Administrative Agent hereunder and without notice to or consent of the Lenders. With respect to its Loans and interests in Letters of Credit issued hereunder, LaSalle shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and the “Lenders” shall include LaSalle in its individual capacity.

SECTION 8.9. Successor Administrative Agent. The Administrative Agent may, and at the request of the Majority Lenders shall, resign as Administrative Agent upon thirty (30) days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor representative for the Lenders. If no successor representative is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders and the Borrower, a successor representative from among the Lenders. Upon the acceptance of its appointment as successor representative hereunder, such successor representative shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor representative and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article VIII and Sections 9.4 and 9.10 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor representative has accepted appointment as Administrative Agent by the date which is thirty (30) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor representative as provided for above. Upon resignation, the Administrative Agent shall execute and deliver such assignments and take such other actions as the Lenders shall reasonably request in order to transfer and assign its rights and interests under the Collateral Documents to the Lenders or any successor representative appointed by the Lenders; provided that any costs and expenses incurred by the Administrative Agent in taking such actions shall be reimbursed in accordance with Section 9.4(a).

SECTION 8.10. Collateral Matters; Release of Collateral.

(a) The Administrative Agent is authorized on behalf of all the Lenders, without the necessity of any notice to or further consent from the Lenders, from time to time to take any action with respect to any Collateral or the Collateral Documents which may be necessary to perfect and maintain perfected the security interest in and Liens upon the Collateral granted pursuant to the Collateral Documents.

(b) The Lenders irrevocably authorize the Administrative Agent, and the Administrative Agent hereby agrees upon the request of the Borrower, to release any Lien granted to or held by the Administrative Agent upon any Collateral (i) upon termination of the Commitments and payment in full of all Loans and all other Obligations (or cash collateralization of any outstanding Letters of Credit in a manner acceptable to the applicable Issuing Lender) payable under this Agreement and under any other Loan Document (other than contingent obligations for which no claim has been, or is reasonably expected to be, made); (ii) constituting property sold or to be sold or disposed of as part of or in connection with any disposition permitted hereunder; (iii) constituting property in which none of the Loan Parties owned any interest at the time the Lien was granted or at any time thereafter; (iv) constituting property leased to any Loan Party under a lease which has expired or been terminated in a transaction permitted under this Agreement or is about to expire and which has not been, and is not intended by such Loan Party to be, renewed or extended; (v) consisting of an instrument evidencing Debt or other debt instrument, if the Debt evidenced thereby has been paid in full; (vi) if required by the Intercreditor Agreement; (vii) with respect to which (A) the Borrower shall have requested in writing that the Administrative Agent release its Lien thereon, (B) the Borrower shall have provided, or caused one or more of its Subsidiaries to provide, substitute Collateral of reasonably equivalent or greater value to that of such Collateral subject to such requested Lien release, (C) the Administrative Agent shall have reasonably determined that such substitute Collateral is otherwise acceptable, (D) such substitute Collateral (and the Administrative Agent’s substitute Lien thereon) shall be subject to documentation reasonably satisfactory to the Administrative Agent and (E) such release and substitution is otherwise made in compliance with Section 3.1 of the Intercreditor Agreement; (viii) with respect to any Liens on the vessels Buster, Jack, Key West and G.L. 142 arising under the Collateral Documents; provided, that (A) the Borrower shall have requested in writing that the Administrative Agent release its Lien thereon, (B) the vessel Ohio shall constitute Collateral at the time of such release (C) the Administrative Agent shall have received a recent appraisal of the vessel Ohio by Merrill Marine or such other appraiser reasonably acceptable to the Administrative Agent providing that the vessel Ohio has an OLV of at least $25,500,000 and (D) the Ohio (and the Administrative Agent’s Lien thereon) shall be subject to documentation reasonably satisfactory to the Administrative Agent, (ix) in connection with any permanent reduction in the Revolving Commitment Amount in accordance with Section 2.2 hereof, in Collateral selected by the Borrower in consultation with the Administrative Agent having an aggregate OLV according to a recent appraisal by Merrill Marine or such other appraiser reasonably acceptable to the Administrative Agent no greater than 50% of the amount of such permanent reduction in the Revolving Commitment Amount or (x) subject to Section 9.1(g), if approved, authorized or ratified in writing by the Majority Lenders. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.10(b). The Administrative Agent hereby agrees to execute and deliver to the Borrower such instruments and documents as are requested by the Borrower (and prepared and filed at Borrower’s sole cost and expense) to effect each release permitted hereunder.

(c) Intercreditor Agreement and other Loan Documents. Except to the extent provided in Section 9.1, each Lender from time to time party hereto authorizes and consents, by its execution hereof or by the Assignment and Acceptance by which it became a Lender, to the Administrative Agent’s entering into the Intercreditor Agreement and each of the other Loan

Documents on such Lender’s behalf and taking all actions taken, required or permitted to be taken by the Administrative Agent thereunder.

ARTICLE IX.

MISCELLANEOUS

SECTION 9.1. Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan Document, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders and the Borrower and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that no amendment, waiver or consent shall, unless in writing and signed by all of the affected Lenders and the Borrower do any of the following: (a) reduce the rate of interest on any Loan or obligation or reduce any fee payable to the Lenders, (b) reduce or forgive the principal of, or interest on, the Loans or any fees or other amounts payable hereunder, (c) postpone any date fixed for any payment of principal (excluding any mandatory prepayment) of, or interest on, the Loans or any fees or other amounts payable hereunder, (d) reduce the percentage specified in the definition of Majority Lenders, (e) extend the expiration of or change the percentage of any of the Commitments or increase the number of the Lenders which shall be required for the Lenders or any of them to take any action hereunder, (f) require additional consents, to be obtained with respect to the sale or any assignment or participation of any Lenders hereunder, (g) release all or substantially all of the Guarantees or the Liens of the Administrative Agent and the Lenders on all or substantially all of the Collateral (other than to the extent permitted by Section 8.10(b)(i), (vi) or (vii) hereof), (h) amend Section 9.17 or the definition of “Alternative Currency” without the written consent of each Lender in a manner which is more burdensome to the Lenders; or (i) amend this Section 9.1 or otherwise modify the voting provisions of this Agreement or amend the definition of Majority Lenders; provided, further, that no amendment, waiver or consent shall (i) unless in writing and signed by the Administrative Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent under this Agreement, (ii) unless in writing and signed by the Swing Line Lender in addition to the Lenders required above to take such action, affect the rights or duties of the Swing Line Lender under this Agreement or (iii) effect an increase in any of the Commitments of any Lender without such Lender’s express written approval.

If, in connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all affected Lenders, the consent of Majority Lenders is obtained but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this Section 9.1 being referred to as a “Non-Consenting Lender”), then, so long as the Lender acting as the Administrative Agent is not a Non-Consenting Lender, at the Borrower’s request, an assignee acceptable to the Administrative Agent shall have the right with the Administrative Agent’s consent and in the Administrative Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Administrative Agent’s request, sell and assign to the Lender acting as the Administrative Agent or such Assignee, all of the interests, rights and obligations under this Agreement (including, without limitation, the Commitments and the Revolving Credit Percentage of the Obligations) of such Non-Consenting Lender for an amount equal to the

principal balance of all Loans held by the Non-Consenting Lender and all accrued interest and fees with respect thereto through the date of sale; provided, however, that such purchase and sale shall not be effective until the Administrative Agent shall have received from such assignee an agreement in form and substance satisfactory to the Administrative Agent and the Borrower whereby such assignee shall agree to be bound by the terms hereof. Each Lender agrees that, if it becomes a Non-Consenting Lender, it shall execute and deliver to the Administrative Agent an Assignment and Acceptance to evidence such sale and purchase and shall deliver to the Administrative Agent any Note (if the assigning Lender’s Loans are evidenced by Notes) subject to such Assignment and Acceptance; provided, however, that the failure of any Non-Consenting Lender to execute an Assignment and Acceptance shall not render such sale and purchase (and the corresponding assignment) invalid.

SECTION 9.2. Notices, Etc.

SECTION 9.3. No Waiver; Remedies. No failure on the part of any Lender or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 9.4. Costs and Expenses; Indemnification. The Borrower agrees (a) to pay or reimburse the Administrative Agent and the Arranger for all their reasonable out-of-pocket costs and expenses incurred in connection with the syndication of the Facilities (other than fees payable to syndicate members) and the development, preparation and execution of, and any

amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements and other charges of counsel to the Administrative Agent and the Arranger, (b) to pay or reimburse each Lender and the Administrative Agent for all their costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, including, without limitation, the fees and disbursements of counsel to each Lender and of counsel to the Administrative Agent, (c) to pay, indemnify, or reimburse each Lender and the Administrative Agent for, and hold each Lender and the Administrative Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay, in paying, stamp, excise and other taxes, if any, which may be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify or reimburse each Lender, the Administrative Agent, the Arranger, their respective affiliates, and their respective officers, directors, trustees, employees, advisors, agents and controlling persons (each, an “Indemnitee”) for, and hold each Indemnitee harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including, without limitation, any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of the Borrower or any of its Subsidiaries or any of the Properties and the fees and disbursements and other charges of legal counsel in connection with claims, actions or proceedings by any Indemnitee against the Borrower hereunder (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”), provided, that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee. No Indemnitee shall be liable for (i) consequential damages as a result of any failure to fund any of the Facilities or (ii) any damages arising from the use by unauthorized Persons of Information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such Persons or for any special, indirect, consequential or punitive damages in connection with the Facilities (unless such damages resulted directly from the gross negligence, bad faith or willful misconduct of the Person claiming the protections of clause (ii)). Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee; provided, however, that the Borrower shall retain all such rights of recovery with respect to any liabilities arising under Environmental Laws resulting from the gross negligence, bad faith or willful misconduct of such Indemnitee. All amounts due

under this Section shall be payable not later than 30 days after written demand therefor. Statements payable by the Borrower pursuant to this Section shall be submitted to Deborah A. Wensel (Telephone No. (630) 574-2948) (Fax No. (630) 574-3007), at the address of the Borrower set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Borrower in a notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder.

SECTION 9.5. Setoff. In addition to and not in limitation of any rights of any Lender under Applicable Law, each Lender shall, upon the occurrence and during the continuance of any Event of Default described in Section 7.1(a) or Section 7.1(e), have the right to appropriate and apply to the payment of the Obligations then due and unpaid, and, as security for such Obligations, each of the Loan Parties hereby grants to each Lender a continuing security interest in, any and all deposits or accounts of the Borrower then or thereafter maintained with such Lender or participant; provided that any such appropriation and application shall be subject to the provisions of Section 2.17. Each Lender agrees promptly to notify the Borrower 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 setoff and application. The rights of each Lender under this Section 9.5 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.6. Effectiveness. This Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent and when the Administrative Agent shall have been notified by each Lender that such Lender has executed it.

SECTION 9.7. Successors and Assigns; Participations and Assignments. (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent, all future holders of the Loans and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent and each Lender.

(b) Any Lender may, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or consent would require the consent of the Lender from which such participation was purchased pursuant to Section 9.1. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each

Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 9.7(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.10, 2.11, 2.12 and 2.16 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender; provided that, in the case of Sections 2.12 and 2.16, such Participant shall have complied with the requirements of said Section, and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

(c) Any Lender (an “Assignor”) may, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any Affiliate, Related Fund or Control Investment Affiliate thereof or, with the written consent of the Borrower and the Administrative Agent and, in the case of any assignment of Revolving Commitments, the written consent of the Issuing Lenders (which, in each case, shall not be unreasonably withheld or delayed) (provided that no such consent need be obtained by the Arranger or any of its Affiliates with respect to any assignment by either of them), to an additional bank, financial institution or other entity (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit A, executed by such Assignee and such Assignor (and, where the consent of the Borrower, the Administrative Agent or the Issuing Lenders is required pursuant to the foregoing provisions, by the Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that no such assignment to an Assignee (other than any Lender or any Affiliate or Related Fund), in the case of an assignment of Revolving Commitments and/or Loans, shall be in an aggregate principal amount of less than $5,000,000 (other than in the case of an assignment of all of a Lender’s interests under this Agreement), and after giving effect thereto, the Assignor, in the case of an assignment of Revolving Commitments and/or Loans, shall have Revolving Commitments and/or Loans aggregating at least $5,000,000 unless otherwise agreed by the Borrower and the Administrative Agent. Any such assignment need not be ratable as among the Facilities. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with Commitments and/or Loans as set forth therein, (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor’s rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to Section 2.10, 2.11, 2.12 and 9.4 in respect of the period prior to such effective date), and (z) the assignee shall comply with Section 2.16 (f). Notwithstanding any provision of this Section, the consent of the Borrower shall not be required for any assignment that occurs at any time when any Event of Default shall have occurred and be continuing. For purposes of the minimum assignment amounts set forth in this paragraph, multiple assignments

by or to two or more Related Funds shall be aggregated. Notwithstanding anything herein to the contrary, neither the Borrower nor any Affiliate thereof may be an “Assignee” hereunder.

(d) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be presumptive evidence of the amounts so entered, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Notes evidencing such Loans recorded therein for all purposes of this Agreement. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the Administrative Agent to the Borrower marked “canceled”. The Register shall be available for inspection by the Borrower or any Lender (with respect to any entry relating to such Lender’s Loans) at any reasonable time and from time to time upon reasonable prior notice.

(e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 9.7(c), by each such other Person) together with payment to the Administrative Agent of a registration and processing fee of $3,500 (except that no such registration and processing fee shall be payable in the case of an Assignee which is already a Lender or is an Affiliate or Related Fund of a Lender or a Person under common management with a Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. On or prior to such effective date, the Borrower, at its own expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the applicable Notes of the assigning Lender) a new Note to the order of such Assignee in an amount equal to the Revolving Commitment assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Revolving Commitment upon request, a new Note and/or Notes, as the case may be, to the order of the Assignor in an amount equal to the Revolving Commitment retained by it hereunder. Such new Note or Notes shall be dated the Closing Date and shall otherwise be in the form of the Note or Notes replaced thereby.

(f) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section 9.7 concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Loans and Notes, including, without limitation, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law.

(g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other Debt of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any state thereof. In addition, notwithstanding anything to the contrary in this Section 9.7(g), any SPC may (A) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender, or with the prior written consent of the Borrower and the Administrative Agent (which consent shall not be unreasonably withheld) to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans, and (B) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC; provided that non-public information with respect to the Borrower may be disclosed only with the Borrower’s consent which will not be unreasonably withheld. This Section 9.7(g) may not be amended without the written consent of any SPC with Loans outstanding at the time of such proposed amendment.

SECTION 9.8. Survival of Warranties and Agreements. All agreements, representations and warranties made herein shall survive the execution and delivery of this Agreement and the other Loan Documents and the making and repayment of the Obligations hereunder.

SECTION 9.9. Marshalling; Recourse to Security; Payments Set Aside.

PROVISIONS OF 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

SECTION 9.14. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

SECTION 9.15. Entire Agreement. This Agreement, together with the other Loan Documents, embodies the entire agreement and understanding among the Loan Parties, the Lenders, the Issuing Lenders and the Administrative Agent, and supersedes all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof, except for the fee letter dated May 7, 2007 among the Borrower and LaSalle, and any prior arrangements made with respect to the payment by the Borrower of (or any indemnification for) any fees, costs or expenses payable to or incurred (or to be incurred) by or on behalf of the Administrative Agent or the Lenders

SECTION 9.16. Non-Confidentiality of Tax Structure. Notwithstanding anything herein to the contrary, each party hereto (and each affiliate and person acting on behalf of any such party) agrees that each party (and each employee, representative, and other agent of such party) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the transaction contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to such party or such Person relating to such tax treatment and tax structure, except to the extent necessary to comply with any applicable federal or state securities laws.

SECTION 9.17. Additional Alternative Currencies.

(a) The Borrower may from time to time request that Eurodollar Rate Loans be made and/or Letters of Credit be issued in a currency other than those specifically listed in the definition of “Alternative Currency;” provided that such requested currency is a lawful currency (other than Dollars) that is readily available and freely transferable and convertible into Dollars. In the case of any such request with respect to the making of Eurodollar Rate Loans, such request shall be subject to the approval of the Administrative Agent and the Lenders; and in the case of any such request with respect to the issuance of Letters of Credit, such request shall be subject to the approval of the Administrative Agent and the applicable Issuing Lender.

(b) Any such request shall be made to the Administrative Agent not later than 11:00 a.m., 10 Business Days prior to the date of the desired Revolving Loan or Letter of Credit (or such other time or date as may be agreed by the Administrative Agent and, in the case of any such request pertaining to Letters of Credit, the Issuing Lenders, in its or their sole discretion).

In the case of any such request pertaining to Eurodollar Rate Loans, the Administrative Agent shall promptly notify each Lender thereof; and in the case of any such request pertaining to Letters of Credit, the Administrative Agent shall promptly notify the applicable Issuing Lender thereof. Each Lender (in the case of any such request pertaining to Eurodollar Rate Loans) or the applicable Issuing Lender (in the case of a request pertaining to Letters of Credit) shall notify the Administrative Agent, not later than 11:00 a.m., five Business Days after receipt of such request whether it consents, in its sole discretion, to the making of Eurodollar Rate Loans or the issuance of Letters of Credit, as the case may be, in such requested currency.

(c) Any failure by a Lender or a Issuing Lender, as the case may be, to respond to such request within the time period specified in the preceding sentence shall be deemed to be a refusal by such Lender or Issuing Lender, as the case may be, to permit Eurodollar Rate Loans to be made or Letters of Credit to be issued in such requested currency. If the Administrative Agent and all the Lenders consent to making Eurodollar Rate Loans in such requested currency, the Administrative Agent shall so notify the Borrower and such currency shall thereupon be deemed for all purposes to be an Alternative Currency hereunder for purposes of any Eurodollar Rate Loans; and if the Administrative Agent and the applicable Issuing Lender consent to the issuance of Letters of Credit in such requested currency, the Administrative Agent shall so notify the Borrower and such currency shall thereupon be deemed for all purposes to be an Alternative Currency hereunder for purposes of any Letter of Credit issuances. If the Administrative Agent shall fail to obtain consent to any request for an additional currency under this Section 9.17, the Administrative Agent shall promptly so notify the Borrower. Any specified currency of an Existing Letter of Credit that is neither Dollars nor one of the Alternative Currencies specifically listed in the definition of “Alternative Currency” shall be deemed an Alternative Currency with respect to such Existing Letter of Credit only.

SECTION 9.18. Exchange Rates; Currency Equivalents.

(a) The Administrative Agent shall determine the Spot Rates as of each Revaluation Date to be used for calculating Dollar Equivalent amounts of Letters of Credit and Revolving Loans denominated in Alternative Currencies. Such Spot Rates shall become effective as of such Revaluation Date and shall be the Spot Rates employed in converting any amounts between the applicable currencies until the next Revaluation Date to occur. Except for purposes of financial statements delivered by Loan Parties hereunder or calculating financial covenants hereunder or except as otherwise provided herein, the applicable amount of any currency (other than Dollars) for purposes of the Loan Documents shall be such Dollar Equivalent amount as so determined by the Administrative Agent.

(b) Wherever in this Agreement in connection with a borrowing, conversion, continuation or prepayment of a Revolving Loan or the issuance, amendment or extension of a Letter of Credit, an amount, such as a required minimum or multiple amount, is expressed in Dollars, but such Revolving Loan or Letter of Credit is denominated in an Alternative Currency, such amount shall be the relevant Alternative Currency Equivalent of such Dollar amount (rounded to the nearest unit of such Alternative Currency, with 0.5 of a unit being rounded upward), as determined by the Administrative Agent.

SECTION 9.19. Cash Collateral. The Borrower hereby grants to the Administrative Agent, for the benefit of the Secured Parties, a security interest in all Cash Collateral delivered by the Borrower in connection with Section 2.8.1.

SECTION 9.20. Syndication Agent and Co-Documentation Agents. No Person named as a “Syndication Agent” or “Co-Documentation Agent” herein shall have any rights or obligations under this Agreement or any other Loan Document in its capacity as “Syndication Agent” or “Co-Documentation Agent.”
