If any such notice is given, the amount specified in such notice shall be due and payable on the date set forth in such notice. Partial prepayments shall be in an aggregate amount of $1,000,000 or a whole multiple of $500,000 in excess thereof with respect to Base Rate Loans (other than Swingline Loans), $1,000,000 or a whole multiple of $500,000 in excess thereof with respect to LIBOR Rate Loans and $100,000 or a whole multiple of $100,000 in excess thereof with respect to Swingline Loans. A Notice of Prepayment received after 12:00 p.m. shall be deemed received on the next Business Day. Each such repayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof. Notwithstanding the foregoing, any Notice of a Prepayment delivered in connection with any refinancing of all of the Revolving Credit Facility with the proceeds of such refinancing or of any incurrence of Indebtedness, may be, if expressly so stated to be, contingent upon the consummation of such refinancing or incurrence and may be revoked by the Borrower in the event such refinancing is not consummated (provided that the failure of such contingency shall not relieve the Borrower from its obligations in respect thereof under Section 5.9).

-41-

(d) Limitation on Prepayment of LIBOR Rate Loans. The Borrower may not prepay any LIBOR Rate Loan on any day other than on the last day of the Interest Period applicable thereto unless such prepayment is accompanied by any amount required to be paid pursuant to Section 5.9 hereof.

SECTION 2.5 Permanent Reduction of the Aggregate Commitment.

(a) Voluntary Reduction. The Borrower shall have the right at any time and from time to time, upon at least five (5) Business Days prior written notice to the Administrative Agent, to permanently reduce, without premium or penalty, (i) the Aggregate Commitment at any time or (ii) portions of the Aggregate Commitment, from time to time, in an aggregate principal amount not less than $1,000,000 or any whole multiple of $500,000 in excess thereof. Any reduction of the Aggregate Commitment shall be applied to the Commitment of each Lender according to its Commitment Percentage; provided that no such reduction, in whole or in part, of the Aggregate Commitment shall be permitted if, after giving effect thereto and to any prepayments of the Loans and/or deposit of Cash Collateral with the Administrative Agent to collateralize the L/C Obligations made concurrently pursuant to clause (b) below, the Dollar Equivalent Amount of the Outstandings would exceed the Aggregate Commitment. All commitment fees accrued until the effective date of any reduction, in whole or in part, of the Aggregate Commitment shall be paid on the effective date of such termination.

(b) Corresponding Payment. Each permanent reduction permitted pursuant to this Section shall be accompanied by a payment of principal sufficient to reduce the aggregate outstanding Revolving Credit Loans, Swingline Loans and L/C Obligations, as applicable, after such reduction to the Aggregate Commitment as so reduced and if the aggregate Dollar Equivalent Amount of all outstanding Letters of Credit exceeds the Aggregate Commitment as so reduced, the Borrower shall be required to deposit in Dollars the Dollar Equivalent Amount of Cash Collateral in a Cash Collateral account opened by the Administrative Agent in an amount equal to such excess. Such Cash Collateral shall be applied in accordance with Section 10.2(b). Any reduction of the Aggregate Commitment to zero shall be accompanied by payment of all outstanding Obligations (and the furnishing of Cash Collateral in an amount equal to 105% of the L/C Obligations at such time) and shall result in the termination of the Aggregate Commitment and the Swingline Commitment and the Revolving Credit Facility. If the reduction of the Agreement Commitment requires the repayment of any LIBOR Rate Loan, such repayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof.

SECTION 2.6 Termination of Revolving Credit Facility. The Revolving Credit Facility and the Aggregate Commitment shall terminate on the Revolving Credit Maturity Date.

(a) Availability. Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 3.4(a), agrees to issue Letters of Credit for the account of the Borrower or (without limiting the Borrower’s obligations with respect thereunder under Section 3.5 or otherwise) any of its Subsidiaries in Dollars or in Alternative Currencies on any Business Day from the Closing Date through but not including the fifth (5^th) Business Day prior to the Revolving Credit Maturity Date in such form as may be approved from time to time by such Issuing Lender; provided, however, that the applicable Issuing Lender shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (a) the L/C Obligations would exceed the L/C Commitment; provided that any Issuing Lender may issue a Letter of Credit in excess of the L/C Commitment if (x) the term of such Letter of Credit is less than one (1) year from the date of issuance and (y) after giving effect to such issuance, the Dollar Equivalent Amount of the Outstandings would not exceed the Aggregate Commitment or (b) the Dollar Equivalent Amount of the Outstandings would exceed the Aggregate Commitment. Each Letter of Credit shall (i) be a standby letter of credit or bank guarantee issued to support obligations of the Borrower or any of its Subsidiaries, contingent or otherwise, (ii) expire on a date no later than the earlier of (A) the fourth anniversary of the date of issuance and (B) June 1, 2018; provided, that (x) 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 subclause (B) above) and (y) no later than five (5) days prior to the Revolving Credit Maturity Date, the Borrower shall Cash Collateralize in Dollars each Letter of Credit, if any, with an expiration date after the Revolving Credit Maturity Date in a Dollar Equivalent Amount equal to 105% of the L/C Obligations with respect to each such Letter of Credit and (iii) be subject to the Uniform Customs, the URDG or ISP98, in each case, as set forth in the related Letter of Credit Application or as determined by the applicable Issuing Lender and, to the extent not inconsistent therewith, the laws of the State of New York. No Issuing Lender shall at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause such Issuing Lender or any L/C Participant to exceed any limits imposed by, any Applicable Law. References herein to “issue” and derivations thereof with respect to Letters of Credit shall also include extensions or modifications of any outstanding Letters of Credit, except (x) any technical or non-substantive modifications or amendments, as determined in the sole discretion of the applicable Issuing Lender or (y) as the context may otherwise require. As of the Closing Date, each of the Existing Letters of Credit shall constitute, for all purposes of this Agreement and the other Loan Documents, a Letter of Credit issued and outstanding hereunder.

(b) Defaulting Lenders. Notwithstanding anything to the contrary contained in this Agreement, Article III shall be subject to the terms and conditions of Section 5.14 and Section 5.15.

-43-

SECTION 3.2 Procedure for Issuance of Letters of Credit. (a) The Borrower may from time to time request that an Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender at such Issuing Lender’s address for notices specified herein (with a copy delivered to the Administrative Agent’s Office) a Letter of Credit Application therefor, completed to the reasonable satisfaction of such Issuing Lender, and such other certificates, documents and other papers and information as such Issuing Lender may reasonably request. Upon receipt of any Letter of Credit Application, the applicable Issuing Lender shall process such Letter of Credit Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall, subject to Section 3.1 and Article VI, promptly issue the Letter of Credit requested thereby (but in no event shall such Issuing Lender be required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Letter of Credit Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by such Issuing Lender and the Borrower. Each Issuing Lender shall promptly furnish to the Borrower and the Administrative Agent a copy of such Letter of Credit and the Administrative Agent shall promptly notify each Lender of the issuance and upon request by any Lender, furnish to such Lender a copy of such Revolving Credit Letter of Credit and the amount of such Lender’s participation therein.

(b) Promptly after receipt of any Letter of Credit Application, the applicable Issuing Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, such Issuing Lender will provide the Administrative Agent with a copy thereof. Unless the applicable Issuing Lender has received written notice from the Administrative Agent at least one Business Day prior to the requested date of issuance of the applicable Letter of Credit, that one or more applicable conditions contained in Article VI shall not then be satisfied, then, subject to the terms and conditions hereof, such Issuing Lender shall, on the requested date, issue a Letter of Credit for the account of the Borrower (or the applicable Subsidiary of the Borrower) in accordance with the terms and conditions set forth herein and otherwise in accordance with such Issuing Lender’s usual and customary business practices.

SECTION 3.3 Commissions and Other Charges.

(a) Letter of Credit Commissions. The Borrower shall pay to the Administrative Agent, for the account of each Issuing Lender and the L/C Participants, a letter of credit commission with respect to each Letter of Credit in the amount equal to (i) the daily amount available to be drawn under such Letter of Credit times (ii) the Applicable Margin applicable to Performance Letters of Credit or Financial Letters of Credit, respectively. Such commission shall be payable quarterly in arrears on the last Business Day of each calendar quarter, on the Revolving Credit Maturity Date and thereafter on demand of the Administrative Agent. The Administrative Agent shall, promptly following its receipt thereof, distribute to each Issuing Lender and the L/C Participants all commissions received pursuant to this Section 3.3 in accordance with their respective Commitment Percentages.

(b) Issuance Fee. In addition to the foregoing commission, the Borrower shall pay to each Issuing Lender, an issuance fee with respect to each Letter of Credit issued by such Issuing Lender (i) with respect to ▇▇▇▇▇ Fargo, as an Issuing Lender, as set forth in the Fee Letter or (ii) with respect to each other Issuing Lender, as separately agreed between the Borrower and

-44-

such Issuing Lender. Such issuance fee shall be payable quarterly in arrears on the last Business Day of each calendar quarter commencing with the first such date to occur after the issuance of such Letter of Credit, on the Revolving Credit Maturity Date and thereafter on demand of the Administrative Agent.

(c) Other Costs. In addition to the foregoing fees and commissions, the Borrower shall pay or reimburse each Issuing Lender for such normal and customary costs and expenses as are incurred or charged by such Issuing Lender in issuing, effecting payment under, amending or otherwise administering any Letter of Credit.

SECTION 3.4 L/C Participations.

(a) Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce the Issuing Lenders to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from such Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Commitment Percentage in such Issuing Lender’s obligations and rights under and in respect of each Letter of Credit issued by such Issuing Lender hereunder and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit for which such Issuing Lender is not reimbursed in full by the Borrower through a Revolving Credit Loan or otherwise in accordance with the terms of this Agreement, such L/C Participant shall pay in Dollars to the Administrative Agent for the account of the applicable Issuing Lender upon demand an amount equal to the Dollar Equivalent Amount (as determined by such Issuing Lender) of such L/C Participant’s Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed.

(b) Upon becoming aware of any amount required to be paid by any L/C Participant to an Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit issued by such Issuing Lender, the Administrative Agent shall notify each L/C Participant of the amount and due date of such required payment and such L/C Participant shall pay in Dollars to such Issuing Lender the Dollar Equivalent Amount (as determined by such Issuing Lender) of the amount specified on the applicable due date. If any such amount is paid to the Administrative Agent for the account of the applicable Issuing Lender after the date such payment is due, such L/C Participant shall pay to the Administrative Agent for the account of the applicable Issuing Lender on demand, in addition to such amount, the product of (i) such amount, times (ii) the daily average Federal Funds Rate as determined by the Administrative Agent during the period from and including the date such payment is due to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. A certificate distributed by the Administrative Agent on behalf of the applicable Issuing Lender with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error. With respect to payment to the applicable Issuing Lender of the unreimbursed amounts described in this Section, if the L/C Participants receive notice that any such payment is due (A) prior to 1:00 p.m. on any Business Day, such payment shall be due that Business Day, and (B) after 1:00 p.m. on any Business Day, such payment shall be due on the following Business Day.

-45-

(c) Whenever, at any time after the applicable Issuing Lender has made payment under any Letter of Credit issued by such Issuing Lender and has received from any L/C Participant its Commitment Percentage of such payment in accordance with this Section, such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise), or any payment of interest on account thereof, such Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, that in the event that any such payment received by such Issuing Lender shall be required to be returned by such Issuing Lender, such L/C Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it.

SECTION 3.5 Reimbursement Obligation of the Borrower. In the event of any drawing under any Letter of Credit, the Borrower agrees to reimburse (either with the proceeds of a Revolving Credit Loan as provided for in this Section or with funds from other sources), in same day funds, the applicable Issuing Lender in Dollars (by payment to the Administrative Agent for the account of such Issuing Lender) on each date on which such Issuing Lender notifies the Borrower of the date and the Dollar Equivalent Amount of a draft paid under any Letter of Credit issued by such Issuing Lender for the Dollar Equivalent Amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by such Issuing Lender in connection with such payment; provided, however, that if such notification is delivered by such Issuing Lender after 12:00 p.m. on any date of payment, then the Borrower shall reimburse such Issuing Lender on the next succeeding Business Day. Unless the Borrower shall immediately notify the applicable Issuing Lender that the Borrower intends to reimburse such Issuing Lender for such drawing from other sources or funds, the Borrower shall be deemed to have timely given a Notice of Borrowing to the Administrative Agent requesting that the Lenders make a Dollar-denominated Revolving Credit Loan bearing interest at the Base Rate on such date in the Dollar Equivalent Amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by such Issuing Lender in connection with such payment, and the Lenders shall make a Revolving Credit Loan bearing interest at the Base Rate in such amount, the proceeds of which shall be applied to reimburse such Issuing Lender for the amount of the related drawing and costs and expenses. Each Lender acknowledges and agrees that its obligation to fund a Revolving Credit Loan in accordance with this Section to reimburse the applicable Issuing Lender for any draft paid under a Letter of Credit issued by such Issuing Lender is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Section 2.3(a) or Article VI. If the Borrower has elected to pay the amount of such drawing with funds from other sources and shall fail to reimburse the applicable Issuing Lender as provided above, the unreimbursed Dollar Equivalent Amount of such drawing shall bear interest at the rate which would be payable on any outstanding Base Rate Loans which were then overdue from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full.

SECTION 3.6 Obligations Absolute. The Borrower’s obligations under this Article III (including, without limitation, the Reimbursement Obligation) shall be absolute and unconditional under any and all circumstances and irrespective of any set off, counterclaim or defense to payment which the Borrower may have or have had against any Issuing Lender or any

-46-

beneficiary of a Letter of Credit or any other Person. The Borrower also agrees that the Issuing Lenders and the L/C Participants shall not be responsible for, and the Borrower’s Reimbursement Obligation under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. The Issuing Lenders shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by any such Issuing Lender’s gross negligence or willful misconduct, as determined by a court of competent jurisdiction by final nonappealable judgment. The Borrower agrees that any action taken or omitted by any Issuing Lender under or in connection with any Letter of Credit issued by such Issuing Lender or the related drafts or documents, if done in the absence of gross negligence or willful misconduct shall be binding on the Borrower and shall not result in any liability of such Issuing Lender or any L/C Participant to the Borrower. The responsibility of each Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit issued by such Issuing Lender shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit. Notwithstanding anything in this Section 3.6 to the contrary, the Borrower may have a claim against such Issuing Lender, and such Issuing Lender may be liable to the Borrower, to the extent, but only to the extent, of any direct (as opposed to indirect, special, punitive, consequential or exemplary) damages suffered by the Borrower which a court of competent jurisdiction determines in a final non-appealable judgment were caused by such Issuing Lender’s gross negligence or willful misconduct or such Issuing Lender’s bad faith or willful or grossly negligent failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit.

SECTION 3.7 Effect of Letter of Credit Application. To the extent that any provision of any Letter of Credit Application related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply.

On and after the Closing Date and on and after each Release Date, the Obligations will be unsecured and remain unsecured (other than with respect to Cash Collateral as provided in other Articles of this Agreement) unless and until, subject to Section 4.3(d), a Perfection Trigger Event occurs, upon the occurrence of which, the Obligations shall be secured by (a) a perfected first priority Lien (or a preferred Ship Mortgage, as the case may be) on Designated Vessels of the Borrower and the Subsidiary Guarantors that (i) as of the Closing Date, have an OLV of at least $260,000,000 in the aggregate and (ii) as of each Increased Amount Date, have an OLV equal to at least 1.5 times the Aggregate Commitment after giving effect to the related Incremental Commitment Increases, in each case,

-47-

according to the appraisal performed prior to the Closing Date with respect to any Designated Vessels covered thereby and, with respect to any other Designated Vessels, an appraisal performed by an Approved Appraiser, (b) a perfected Lien on all accounts receivables of the Borrower and the Subsidiary Guarantors arising out of the rendering of services by the Borrower or any such Subsidiary Guarantor in the United States (subject only to Permitted Liens) and (c) all proceeds of any and all of the foregoing (clauses (a) through (c), collectively, the “Collateral”). The Administrative Agent shall not, nor shall the Required Lenders direct the Administrative Agent to, deliver a Perfection Trigger Notice to the Borrower or the Escrow Agent, unless (x) one or more of the events described in clauses (a)(i) through (a)(iii) of the definition of Perfection Trigger Event shall have occurred and (y) if such Perfection Trigger Notice is to be delivered solely on the basis of the event described in clause (a)(ii) of the definition of Perfection Trigger Event, the conditions set forth in the proviso in the definition of Perfection Trigger Notice permitting the delivery of such notice shall have been satisfied. Upon the occurrence of a Perfection Trigger Event and the delivery of the Escrowed Documents by the Escrow Agent to the Administrative Agent in accordance with the terms of the Escrow Agreement, the Administrative Agent shall take such actions as may be necessary or advisable, in its sole determination, to perfect such Liens in the Collateral, as soon as practicable following its receipt of the Escrowed Documents from the Escrow Agent.

SECTION 4.2 Substitution of Collateral. The Borrower may at any time (including prior to the commencement of a Perfection Period) provide flag vessels in substitution (“Substituted Vessels”) for any Designated Vessel subject to, or that may become subject to, the Lien on the Collateral granted to the Administrative Agent, for the benefit of the Secured Parties, upon a Perfection Trigger Event in accordance with the Security Documents; provided, that (a) the aggregate OLV of all Designated Vessels, after giving effect to the Substituted Vessels, is equal to at least (i) prior to the first Incremental Commitment Increase, $260,000,000 and (ii) on and after each Incremental Commitment Increase, 1.5 times the Aggregate Commitment, immediately after giving effect to such Incremental Commitment Increase; provided, that the OLV of the Substituted Vessels shall be determined by an appraisal from an Approved Appraiser conducted within 90 days (or such earlier date as the Administrative Agent may determine in its sole discretion) prior to the related Increased Amount Date and (b) prior to giving effect to the substitution of Substituted Vessels, the Borrower shall execute and deliver, or cause the other Credit Parties to execute and deliver, Ship Mortgages and other additional Security Documents (including, without limitation, such opinions, resolutions, certificates and other instruments related thereto as may be reasonably requested by the Administrative Agent) reasonably acceptable to the Administrative Agent with respect to each Substituted Vessel to (x) at all times prior to the Springing Lien Termination Date (other than during a Perfection Period), the Escrow Agent and (y) at all times during a Perfection Period, the Administrative Agent.

SECTION 4.3 Release of Collateral. (a) If at any time a Perfection Trigger Event has occurred and the Administrative Agent maintains perfected Liens in any of the Collateral pursuant to the Security Documents, such Liens shall be (subject to the proviso below) released and terminated on the date (a “Release Date”) on which the Administrative Agent (in its sole determination) confirms in writing (such written confirmation not to be unreasonably withheld or delayed) to the Borrower, following the receipt by the Administrative Agent of a certificate executed by the chief financial officer or treasurer of the Borrower certifying clauses (i) and (ii) below, that:

-48-

(i) No Event of Default has occurred and is continuing, and

(ii) The Borrower has maintained a Consolidated Total Leverage Ratio less than or equal to the Trigger Leverage Ratio for the two (2) consecutive fiscal quarters most recently ended with respect to which financial statements have been delivered to the Lenders pursuant to Section 8.1(a) or (b) and is projected to maintain a Consolidated Total Leverage Ratio less than or equal to the Trigger Leverage Ratio for the next two (2) consecutive fiscal quarters;

provided, however, that the release of the Administrative Agent’s Liens on the Collateral and the occurrence of the Release Date shall be further conditioned upon (x) if at the time any Surety has perfected a Lien on any of the Collateral, such Surety has terminated or, concurrently with the Administrative Agent, will terminate such perfection or (y) if at the time no Surety has perfected a Lien on any of the Collateral, no Surety has notified the Administrative Agent of its intention to perfect a Lien on any of the Collateral.

(b) As soon as practicable after the Release Date, if any, and the termination by each Surety of the perfection of its respective Liens on the Collateral, the Administrative Agent shall, at the sole cost and expense of the Borrower, execute and deliver such agreements, documents and instruments, in form and substance reasonably acceptable to the Borrower and the Administrative Agent, to evidence and effect the release and termination of the Administrative Agent’s Liens on the Collateral.

(c) On each Release Date occurring prior to the Springing Lien Termination Date, the Borrower shall, and shall cause its Credit Parties to, execute and deliver (i) to the Escrow Agent (and shall be deemed to have been delivered to the Administrative Agent) new Security Documents, including, without limitation, new Ship Mortgages, a new Receivables Security Agreement and all other agreements, documents and instruments (collectively, the “Replacement Escrowed Documents”) in a form reasonably satisfactory to the Administrative Agent to evidence each such Credit Party’s prospective grant and perfection of Liens on the Property that would constitute Collateral and (ii) to the Administrative Agent, all opinions, resolutions, certificates and other instruments reasonably requested by the Administrative Agent in connection with the delivery of the Escrowed Documents.

(d) On and after the Springing Lien Termination Date, (i) this Article IV and all other provisions hereunder and under the other Loan Documents relating to a Perfection Trigger Event shall be of no further force or effect, (ii) to the extent that the Administrative Agent has perfected its Lien on the Collateral, all such Liens shall be released and terminated and (iii) the appointment of the Escrow Agent and the arrangements set forth under the Escrow Agreement shall terminate and be of no further force or effect in accordance with the terms thereunder. The Obligations shall thereafter remain unsecured (other than with respect to Cash Collateral that may be required pursuant to other Articles of this Agreement). As soon as practicable after Administrative Agent receives notice from the Borrower that the Springing Lien Termination Date has occurred, the Administrative Agent shall, at the sole cost and expense of the Borrower, (i) execute and deliver such agreements, documents and instruments as the Borrower may reasonably request, in form and substance reasonably acceptable to the Borrower and the Administrative Agent, to evidence and effect the release and termination of the Administrative Agent’s Liens on the Collateral and to terminate the Security Documents and (ii) execute and deliver to the Escrow Agent, jointly with the Borrower, a notice in the form of Exhibit B-2 attached to the Escrow Agreement.

SECTION 4.4 Escrow Agent. The Borrower shall cause to be delivered to the Administrative Agent a copy of the Escrow Agreement pursuant to which the Escrow Agent shall deliver, notwithstanding any contrary instructions delivered by the Borrower or any other Person, the Escrowed Documents to the Administrative Agent within three (3) Business Days of the Escrow Agent’s receipt of a Perfection Trigger Notice from the Administrative Agent.

SECTION 4.5 Appraisals. To the extent that no Release Date has occurred prior to the one-year anniversary of the commencement of any Perfection Period, the Borrower shall, upon written request of the Administrative Agent or the Required Lenders, promptly deliver (but in no event more than 45 days (or, at the sole discretion of the Administrative Agent, no more than 60 days) after the receipt of the Administrative Agent’s or the Required Lender’s, as applicable, request) to the Administrative Agent updated appraisals of the Designated Vessels from an Approved Appraiser in similar form and scope as the appraisals delivered to the Administrative Agent pursuant to Section 6.1(d)(iv); provided, that neither the Administrative Agent nor the Required Lenders may request updated appraisals more often than once during any calendar year.

SECTION 4.6 Further Assurances. (a) During each Perfection Period, the Borrower shall maintain the security interest created by the Security Documents in accordance with the terms thereof, subject to the rights of the Credit Parties to dispose of the Collateral pursuant to the Loan Documents or substitute certain Collateral pursuant to Section 4.2.

(b) (i) At all times after the Closing Date, regardless of the occurrence of any Perfection Period, the Borrower shall, and shall cause each Credit Party to, make, execute and deliver all such additional and further agreements, instruments and documents as the Administrative Agent or the Required Lenders (through the Administrative Agent) may reasonably require for the purposes of implementing or effectuating the provisions of this Agreement and the other Loan Documents, and (ii) at all times prior to the Springing Lien Termination Date, the Borrower shall, and shall cause each Credit Party to, make, execute and deliver all such additional and further agreements, instruments and documents as the Administrative Agent or the Required Lenders (through the Administrative Agent) may reasonably require for the purposes of renewing the rights of the Secured Parties with respect to the Collateral pledged, or to be pledged to, the Administrative Agent, for the ratable benefit of the Secured Parties, including, without limitation, (A) authorizing the filing of any financing or continuation statements under the UCC (or other similar laws) in effect in any jurisdiction with respect to the security interests created by the Loan Documents upon the occurrence of any Perfection Trigger Event and (B) executing amendments to the Ship Mortgages to provide for any changes in the Applicable Law governing the security interests in, and Liens on, any of the Designated Vessels pledged thereunder, or to provide for any change in the nature of any of the Collateral or Property that would constitute Collateral that may affect the creation or perfection of any security interests or Liens of the Administrative Agent.

-50-

(c) Each Credit Party agrees to take any and all actions necessary to defend title to the Collateral or Property that would constitute Collateral against all Persons, and at all times during a Perfection Period, to defend the security interest of the Administrative Agent, for the benefit of the Lenders, in the Collateral and the priority thereof against any Lien, other than Permitted Liens.

SECTION 4.7 Collateral Covenants. At all times prior to the Springing Lien Termination Date, each Credit Party:

(a) will not transfer or change the flag of, or change the vessel name or vessel number of, any of the Designated Vessels without the prior written consent of the Administrative Agent; provided, that the Administrative Agent shall not grant any such written consent unless (i) the Administrative Agent is satisfied that all actions necessary or desirable have been taken so that after giving effect to the proposed transfer or change, the Ship Mortgage related to such Designated Vessel, as modified to reflect such transfer or change, is in the form required pursuant to Section 7.12 and benefits to the Administrative Agent with respect to such Designated Vessel at least as favorable as those granted to the Administrative Agent under the original Ship Mortgage or (ii) the related Credit Party provides Substituted Vessel(s) in substitution of such Designated Vessel that are reasonably acceptable to the Administrative Agent and have an aggregate OLV reasonably equal to or greater than (or such lesser OLV as reasonably acceptable to the Administrative Agent) the OLV of such Designated Vessel; provided, further, that any such consent, once obtained shall not be construed to be a waiver of this provision with respect to any subsequent proposed transfer or change of flag, or change in the vessel name or vessel number;

(b) will not (i) cause or permit any Designated Vessel to be operated in any manner contrary to law, (ii) engage in any unlawful trade or violate any law or expose any Designated Vessel to penalty or forfeiture, except where any such operation, engagement, violation or exposure could not reasonably be expected to have a Material Adverse Effect or (iii) do, or suffer or permit to be done, anything which can or may injuriously affect, in any material respect, the registration, documentation or trade endorsement of a Designated Vessel under the laws and regulations of the United States, the Republic of the ▇▇▇▇▇▇▇▇ Islands, or such other jurisdiction governing the documentation or registration of such Designated Vessel;

(c) in the event that any claim or lien is asserted against any Designated Vessel for loss, damage or expense which is covered by insurance required hereunder, and it is necessary for such Credit Party to obtain a bond or supply other security to prevent arrest of such Designated Vessel or to release the Designated Vessel from arrest on account of such claim or lien, shall promptly notify the Administrative Agent in writing of any such arrest or threatened arrest and within thirty (30) days, cause such Designated Vessel to be released by posting security or otherwise;

(d) will not (i) do or permit or willingly allow to be done any act to cause any insurance required by the terms of this Agreement or any Ship Mortgage to be suspended, impaired or cancelled, and (ii) permit or allow any Designated Vessel to undertake any voyage or run any risk or transport any cargo or passengers which may not be permitted by the policies in force, without having previously insured such Designated Vessel by additional coverage extending to such voyages, risks, passengers or cargos;

-51-

(e) shall promptly notify the Administrative Agent of the actual or constructive total loss of a Designated Vessel or the agreed or compromised total loss of a Designated Vessel, or the arrest capture, condemnation, confiscation, registration, seizure or forfeiture of a Designated Vessel;

(f) shall keep its chief executive office and the offices where it keeps its records concerning the “Account Collateral” (as defined in the Receivables Security Agreement) at the location specified in the Receivables Security Agreement or, upon reasonable (but in any event, not less than 7 days’) prior written notice to the Administrative Agent, at such other locations in a jurisdiction where all action that may be reasonably necessary or desirable or that the Administrative Agent may reasonably request in order to, upon the occurrence of a Perfection Trigger Event, perfect and protect any security interest granted or purported to be granted thereunder, or to enable the Administrative Agent to exercise and enforce its rights and remedies under the Receivables Security Agreement with respect to such Account Collateral; and

(g) except upon reasonable (but in any event, not less than 7 days’) prior written notice to Administrative Agent, will not change its legal name or organizational identification number, if any, or corporation, limited liability company, partnership or other organizational structure to such an extent that any UCC financing statement included in the Escrowed Documents in connection with this Agreement would become seriously misleading.

GENERAL LOAN PROVISIONS

SECTION 5.1 Interest.

(a) Interest Rate Options. Subject to the provisions of this Section, at the election of the Borrower, (i) Revolving Credit Loans shall bear interest at (A) the Base Rate plus the Applicable Margin or (B) the LIBOR Rate plus the Applicable Margin (provided that the LIBOR Rate shall not be available until three (3) Business Days after the Closing Date unless the Borrower has delivered to the Administrative Agent a letter in form and substance reasonably satisfactory to the Administrative Agent indemnifying the Lenders in the manner set forth in Section 5.9 of this Agreement) and (ii) any Swingline Loan shall bear interest at the Base Rate plus the Applicable Margin. The Borrower shall select the rate of interest and Interest Period, if any, applicable to any Loan at the time a Notice of Borrowing is given or at the time a Notice of Conversion/Continuation is given pursuant to Section 5.2. Any Loan or any portion thereof as to which the Borrower has not duly specified an interest rate as provided herein shall be deemed a Base Rate Loan.

(b) Interest Periods. In connection with each LIBOR Rate Loan, the Borrower, by giving notice at the times described in Section 2.3 or 5.2, as applicable, shall elect an interest period (each, an “Interest Period”) to be applicable to such Loan, which Interest Period shall be a period of one (1), two (2), three (3), or six (6) months or, if agreed by all of the relevant Lenders, nine (9) or twelve (12) months; provided that:

-52-

(i) the Interest Period shall commence on the date of advance of or conversion to any LIBOR Rate Loan and, in the case of immediately successive Interest Periods, each successive Interest Period shall commence on the date on which the immediately preceding Interest Period expires;

(ii) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided, that if any Interest Period with respect to a LIBOR Rate Loan would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the immediately preceding Business Day;

(iii) any Interest Period with respect to a LIBOR Rate Loan that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall end on the last Business Day of the relevant calendar month at the end of such Interest Period;

(iv) no Interest Period shall extend beyond the Revolving Credit Maturity Date; and

(v) there shall be no more than eight (8) Interest Periods in effect at any time.

(c) Default Rate. Subject to Section 10.3, (i) immediately upon the occurrence and during the continuance of an Event of Default under Section 10.1(a), (b), (i) or (j), or (ii) at the election of the Required Lenders, upon the occurrence and during the continuance of any other Event of Default, (A) the Borrower shall no longer have the option to request LIBOR Rate Loans, Swingline Loans or Letters of Credit, (B) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum of two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to LIBOR Rate Loans until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans, (C) all outstanding Base Rate Loans and other Obligations arising hereunder or under any other Loan Document shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans or such other Obligations arising hereunder or under any other Loan Document and (D) all accrued and unpaid interest shall be due and payable on demand of the Administrative Agent. Interest shall continue to accrue on the Obligations after the filing by or against the Borrower of any petition seeking any relief in bankruptcy or under any act or law pertaining to insolvency or debtor relief, whether state, federal or foreign.

(d) Interest Payment and Computation. Interest on each Base Rate Loan shall be due and payable in arrears on the last Business Day of each calendar quarter commencing June 30, 2012; and interest on each LIBOR Rate Loan shall be due and payable on the last day of each Interest Period applicable thereto, and if such Interest Period extends over three (3) months, at the end of each three (3) month interval during such Interest Period. All computations of interest

-53-

for Base Rate Loans when the Base Rate is determined by the Prime Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest provided hereunder shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365/366-day year).

(e) Maximum Rate. In no contingency or event whatsoever shall the aggregate of all amounts deemed interest under this Agreement charged or collected pursuant to the terms of this Agreement exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent’s option (i) promptly refund to the Borrower any interest received by the Lenders in excess of the maximum lawful rate or (ii) apply such excess to the principal balance of the Obligations on a pro rata basis. It is the intent hereof that the Borrower not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the Borrower under Applicable Law.

SECTION 5.2 Notice and Manner of Conversion or Continuation of Loans. Provided that no Default or Event of Default has occurred and is then continuing, the Borrower shall have the option to (a) convert at any time following the third Business Day after the Closing Date all or any portion of any outstanding Base Rate Loans (other than Swingline Loans) in a principal amount equal to $1,000,000 or any whole multiple of $500,000 in excess thereof into one or more LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert all or any part of its outstanding LIBOR Rate Loans in a principal amount equal to $1,000,000 or a whole multiple of $500,000 in excess thereof into Base Rate Loans (other than Swingline Loans) or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the Borrower desires to convert or continue Loans as provided above, the Borrower shall give the Administrative Agent irrevocable (except as otherwise expressly provided herein) prior written notice in the form attached as Exhibit E (a “Notice of Conversion/Continuation”) not later than 12:00 p.m. three (3) Business Days before the day on which a proposed conversion or continuation of such Loan is to be effective specifying (A) the Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to be converted or continued, the last day of the Interest Period therefor, (B) the effective date of such conversion or continuation (which shall be a Business Day), (C) the principal amount of such Loans to be converted or continued, and (D) the Interest Period to be applicable to such converted or continued LIBOR Rate Loan. The Administrative Agent shall promptly notify the affected Lenders of such Notice of Conversion/Continuation. Each LIBOR Rate Loan shall automatically convert to a Base Rate Loan at the end of the Interest Period applicable thereto, unless the Borrower shall have delivered to the Administrative Agent a Notice of Conversion/Continuation not less than three (3) Business Days prior to the last day of the Interest Period applicable thereto.

-54-

SECTION 5.3 Fees.

(a) Commitment Fee. Commencing on the Closing Date, the Borrower shall pay to the Administrative Agent, for the account of the Lenders, a non-refundable commitment fee (the “Commitment Fee”) at a rate per annum equal to the Applicable Margin on the average daily unused portion of the Aggregate Commitment of the Lenders (other than the Defaulting Lenders, if any); provided, that the amount of outstanding Swingline Loans shall not be considered usage of the Aggregate Commitment for the purpose of calculating the Commitment Fee. The Commitment Fee shall be payable in arrears on the last Business Day of each calendar quarter during the term of this Agreement commencing June 30, 2012 and ending on the Revolving Credit Maturity Date. Such commitment fee shall be distributed by the Administrative Agent to the Lenders (other than any Defaulting Lender) pro rata in accordance with such Lenders’ respective Commitment Percentages.

(b) Other Fees. The Borrower shall pay to the Arranger and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the Fee Letter. The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified.

SECTION 5.4 Manner of Payment.

(a) Sharing of Payments. Each payment by the Borrower on account of the principal of or interest on the Loans or of any fee, commission or other amounts (including the Reimbursement Obligation) payable to the Lenders under this Agreement shall be made to the Administrative Agent, for the account of the Lenders entitled to such payment, not later than 2:00 p.m. at the Administrative Agent’s Office on the date specified for payment under this Agreement, in immediately available funds (i) with respect to any Revolving Credit Loan denominated in an Alternative Currency, in the type of currency in which Revolving Credit Loan was made or (ii) with respect to all other Extensions of Credit, in Dollars, and shall be made without any set off, counterclaim or deduction whatsoever. Any payment received after such time but before 3:00 p.m. on such day shall be deemed a payment on such date for the purposes of Section 10.1, but for all other purposes shall be deemed to have been made on the next succeeding Business Day. Any payment received after 3:00 p.m. shall be deemed to have been made on the next succeeding Business Day for all purposes. Notwithstanding the foregoing provisions of this Section, if, after the making of any Revolving Credit Loan in any Alternative Currency, the Borrower is prohibited by any Applicable Law from making any payment required hereunder to the Administrative Agent for the account of the Lenders in the type of currency in which such Revolving Credit Loan was made, then all payments to be made by the Borrower hereunder in such currency shall instead be made when due in Dollars in an amount equal to the Dollar Equivalent Amount (as of the date of repayment) of such payment due, it being the intention of the parties hereto that the Borrower takes all risks of the imposition of any such Applicable Law. Upon receipt by the Administrative Agent of each such payment, the Administrative Agent shall distribute to each such Lender at its address for notices set forth herein its Commitment Percentage in respect of the Revolving Credit Facility (or other applicable share as provided herein) of such payment and shall wire advice of the amount of such credit to each Lender. Each payment to the Administrative Agent on account of the principal of or interest on the Swingline Loans or of any fee, commission or other amounts payable to the Swingline Lender shall be made in like manner, but for the account of the Swingline Lender. Each payment to the Administrative Agent of the Issuing Lenders fees or L/C Participants’

-55-

commissions shall be made in like manner, but for the account of the applicable Issuing Lender or the L/C Participants, as the case may be. Each payment to the Administrative Agent of Administrative Agent’s fees or expenses shall be made for the account of the Administrative Agent and any amount payable to any Lender under Sections 5.9, 5.10, 5.11 or 12.3 shall be paid to the Administrative Agent for the account of the applicable Lender. Subject to Section 5.1(b)(ii), if any payment under this Agreement shall be specified to be made upon a day which is not a Business Day, it shall be made on the next succeeding day which is a Business Day and such extension of time shall in such case be included in computing any interest if payable along with such payment.

(b) Defaulting Lenders. Notwithstanding the foregoing clause (a), if there exists a Defaulting Lender each payment by the Borrower to such Defaulting Lender hereunder shall be applied in accordance with Section 5.14(b).

SECTION 5.5 Evidence of Indebtedness.

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

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

SECTION 5.6 Adjustments. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations (other than pursuant to Sections 5.9, 5.10, 5.11 or 12.3) greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the

-56-

Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and

(ii) the provisions of this paragraph shall not be construed to apply to (A) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (B) the application of Cash Collateral provided for in Section 5.14 or (C) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in Swingline Loans and Letters of Credit to any assignee or participant, other than to the Borrower or any of its Subsidiaries (as to which the provisions of this paragraph shall apply).

Each Credit Party consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Credit Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Credit Party in the amount of such participation.

SECTION 5.7 Obligations of Lenders.

(a) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Sections 2.3(b) and 4.2 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the daily average Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

-57-

(b) Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans and issue or participate in Letters of Credit are several and are neither joint nor joint and several. The failure of any Lender to make available its Commitment Percentage of any Loan requested by the Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Commitment Percentage of such Loan available on the borrowing date, but no Lender shall be responsible for the failure of any other Lender to make its Commitment Percentage of such Loan available on the borrowing date.

SECTION 5.8 Changed Circumstances.

(a) Circumstances Affecting LIBOR Rate Availability. In connection with any request for a LIBOR Rate Loan or a Base Rate Loan as to which the interest rate is determined with reference to LIBOR or a conversion to or continuation thereof, if for any reason (i) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Loan, (ii) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for the ascertaining the LIBOR Rate for such Interest Period with respect to a proposed LIBOR Rate Loan or any Base Rate Loan as to which the interest rate is determined with reference to LIBOR or (iii) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the LIBOR Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loans during such Interest Period, then the Administrative Agent shall promptly give notice thereof to the Borrower and each Lender. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, the obligation of the Lenders to make LIBOR Rate Loans or Base Rate Loan as to which the interest rate is determined with reference to LIBOR and the right of the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan or a Base Rate Loan as to which the interest rate is determined with reference to LIBOR shall be suspended, and (i) in the case of LIBOR Rate Loans, the Borrower shall either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such LIBOR Rate Loan together with accrued interest thereon (subject to Section 5.1(d)), on the last day of the then current Interest Period applicable to such LIBOR Rate Loan; or (B) convert the then outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as to which the interest rate is not determined by reference to LIBOR as of the last day of such Interest Period; or (ii) in the case of Base Rate Loans as to which the interest rate is determined by reference to LIBOR, the Borrower shall convert the then outstanding principal amount of each such Loan to a Base Rate Loan as to which the interest rate is not determined by reference to LIBOR as of the last day of such Interest Period. Upon receipt of such notice, the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of LIBOR Rate Loans or, failing that, will be deemed to have converted such request into a request for a borrowing of Base Rate Loans in the amount specified therein

-58-

(b) Laws Affecting LIBOR Rate Availability. If any Lender reasonably determines, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Offices) to honor its obligations hereunder to make or maintain any LIBOR Rate Loan or any Base Rate Loan as to which the interest rate is determined by reference to LIBOR, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrower that such Lender has reasonably determined that such circumstances no longer exist, (i) the obligations of the Lenders to make LIBOR Rate Loans or Base Rate Loans as to which the interest rate is determined by reference to LIBOR, and the right of the Borrower to convert any Loan to a LIBOR Rate Loan or continue any Loan as a LIBOR Rate Loan or a Base Rate Loan as to which the interest rate is determined by reference to LIBOR shall be suspended and thereafter the Borrower may select only Base Rate Loans as to which the interest rate is not determined by reference to LIBOR hereunder, (ii) all Base Rate Loans shall cease to be determined by reference to LIBOR and (iii) if any of the Lenders may not lawfully continue to maintain a LIBOR Rate Loan to the end of the then current Interest Period applicable thereto, the applicable Loan shall immediately be converted to a Base Rate Loan as to which the interest rate is not determined by reference to LIBOR for the remainder of such Interest Period.

SECTION 5.9 Indemnity. The Borrower hereby indemnifies each of the Lenders against any loss or expense (including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain a LIBOR Rate Loan or from fees payable to terminate the deposits from which such funds were obtained) which may arise or be attributable to each Lender’s obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any Loan (a) as a consequence of any failure by the Borrower to make any payment when due of any amount due hereunder in connection with a LIBOR Rate Loan, (b) due to any failure of the Borrower (for a reason other than the failure of a Lender to make a Loan) to borrow, continue or convert on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation or (c) due to any payment, prepayment or conversion of any LIBOR Rate Loan on a date other than the last day of the Interest Period therefor. The amount of such loss or expense shall be determined, in the applicable Lender’s sole discretion, based upon the assumption that such Lender funded its Commitment Percentage of the LIBOR Rate Loans in the London interbank market and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the Borrower through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error.

SECTION 5.10 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

-59-

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or advances, loans or other credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate) or any Issuing Lender;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes and (B) Excluded Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto, or

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

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender, such Issuing Lender or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, such Issuing Lender or such other Recipient hereunder (whether of principal, interest or any other amount) then, upon receipt of written notice from such Lender, such Issuing Lender or other Recipient, the Borrower shall promptly pay to any such Lender, such Issuing Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered (it being understood that the provisions set forth in this Section are not intended to derogate from the Borrower’s rights provided in Section 5.12).

(b) Capital Requirements. If any Lender or any Issuing Lender determines that any Change in Law affecting such Lender or such Issuing Lender or any lending office of such Lender or such Lender’s or such Issuing Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Lender’s capital or on the capital of such Lender’s or such Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Commitment of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by such Issuing Lender, to a level below that which such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Lender’s policies and the policies of such Lender’s or such Issuing Lender’s holding company with respect to capital adequacy), then from time to time upon written request of such Lender or such Issuing Lender, the Borrower shall promptly pay to such Lender or such Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company for any such reduction suffered (it being understood that the provisions set forth in this Section are not intended to derogate from the Borrower’s rights provided in Section 5.12).

-60-

(c) Certificates for Reimbursement. A certificate of a Lender or the applicable Issuing Lender or Recipient setting forth the amount or amounts (together with a description and calculation of such amounts) necessary to compensate such Lender, Recipient or such Issuing Lender or their respective holding company, as the case may be, as specified in clause (a) or (b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Lender, as the case may be, the amount shown as due on any such certificate within fifteen (15) Business Days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or any Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or any Issuing Lender pursuant to this Section for any amounts incurred or reductions suffered more than 180 days prior to the date that such Lender or such Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or such Issuing Lender’s intention to claim compensation therefor (except that if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof, but in any event, shall not extend more than 365 days prior to the date that such notice was received by the Borrower).

SECTION 5.11 Taxes.

(a) Issuing Lender. For purposes of this Section 5.11, the term “Lender” includes the Issuing Lenders.

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

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

-61-

(d) Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 30 days after written demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability, with a reasonably detailed calculation thereof, delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority pursuant to this Section 5.11, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(f) Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 5.11(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

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

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

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

(iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-2 or Exhibit J-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-4 on behalf of each such direct and indirect partner;

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

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably

-63-

requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

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

(g) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.11 (including by the payment of additional amounts pursuant to this Section 5.11), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(h) Indemnification of the Administrative Agent. Each Lender and each Issuing Lender shall severally indemnify the Administrative Agent within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.10(e) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this clause (h). The agreements in this clause (h) shall survive the resignation and/or replacement of the Administrative Agent.

-64-

(i) Survival. Each party’s obligations under this Section 5.11 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Aggregate Commitment and the repayment, satisfaction or discharge of all obligations under any Loan Document.

SECTION 5.12 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender or any Issuing Lender ceases to fund LIBOR Rate Loans (or Base Rate Loans as to which the interest rate is determined with reference to LIBOR) as a result of a condition described in Section 5.8, requests compensation under Section 5.10, or requires the Borrower to pay additional amounts to any Lender, any Issuing Lender or any Governmental Authority for the account of any Lender or any Issuing Lender pursuant to Section 5.11, then such Lender or Issuing Lender shall, at the request of the Borrower, use reasonable efforts to designate a different lending office for funding, issuing or booking any Loan or Letter of Credit hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) (x) would avoid the suspension of funding such LIBOR Rate Loans (or Base Rate Loans as to which the interest rate is determined with reference to LIBOR) or (y) would eliminate or reduce amounts payable pursuant to Section 5.10 or Section 5.11, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 5.10, if the Borrower is required to pay additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.11, or any Lender ceases to fund LIBOR Rate Loans (or Base Rate Loans as to which the interest rate is determined with reference to LIBOR) as a result of any condition described in Section 5.8, and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 5.12(a), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, either (i) terminate the Commitment of such Lender or Issuing Lender and (A) in the case of a Lender (other than an Issuing Lender), repay all Obligations of the Borrower owing to such Lender relating to the Loans held by, and the Commitments of, such Lender as of such termination date and (B) in the case of an Issuing Lender, repay all Obligations of the Borrower owing to such Issuing Lender relating to the Loans held by the Issuing Lender as of such termination date and cancel, backstop on terms satisfactory to such Issuing Lender or Cash Collateralize any Letters of Credit issued by it, or (ii) require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.10), all of its interests, rights (other than its existing rights to payments pursuant to Section 5.10 or 5.11) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

-65-

(i) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in draws under Letters of Credit which have not been reimbursed, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.9) from the assignee or the Borrower, as the case may be;

(ii) in the case of any such assignment resulting from a claim for compensation under Section 5.10 or payments required to be made pursuant to Section 5.11, such assignment will result in a reduction in such compensation or payments thereafter;

(iii) such assignment does not conflict with Applicable Law;

(iv) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent; and

(v) either the Borrower or the applicable assignee shall have paid any applicable processing and recordation fee.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 5.13 Incremental Loans. (a) At any time the Borrower may by written notice to the Administrative Agent elect to request the establishment of one or more increases in the Aggregate Commitment (each such increase, an “Incremental Commitment Increase” and, all such increases, collectively, the “Incremental Commitment Increases”) to make incremental Revolving Credit Loans (any such incremental Revolving Credit Loan, an “Incremental Loan”); provided that (1) the total aggregate amount for all such Incremental Commitment Increases shall not (as of any date of incurrence thereof) exceed the amount of $50,000,000 and (2) the total aggregate amount for each Incremental Commitment Increase (and the Incremental Loans made thereunder) shall not be less than the amount of $10,000,000 or, if less, the remaining amount permitted pursuant to the foregoing clause (1). Each such notice shall specify the date (each, an “Increased Amount Date”) on which the Borrower proposes that any Incremental Commitment Increase shall be effective, which shall be a date not less than ten (10) Business Days after the date on which such notice is delivered to Administrative Agent. The Borrower may invite any Lender, any Affiliate of any Lender and/or any Approved Fund, and/or any other Person reasonably satisfactory to the Administrative Agent, to provide an Incremental Commitment Increase (any such Person, an “Incremental Lender”). Any Lender or any Incremental Lender offered or approached to provide all or a portion of any Incremental Commitment Increase may elect or decline, in its sole discretion, to provide such Incremental Commitment Increase. Any Incremental Commitment Increase shall become effective as of such Increased Amount Date; provided that:

-66-

(A) no Default or Event of Default shall exist on such Increased Amount Date before or after giving effect to any Incremental Commitment Increase;

(B) the Administrative Agent and the Lenders shall have received from the Borrower an Officer’s Compliance Certificate demonstrating that the Borrower will be in compliance on a pro forma basis with the financial covenants set forth in Section 9.14 both before and after giving effect to any Incremental Commitment Increase and the making of any Incremental Loans on such Increased Amount Date;

(C) each Incremental Commitment Increase (and the Incremental Loans made thereunder) shall constitute Obligations of the Borrower and shall be guaranteed, and to the extent a Perfection Trigger Event has occurred or thereafter occurs, secured with the other Extensions of Credit on a pari passu basis;

(D) in the case of each Incremental Commitment Increase (the terms of which shall be set forth the relevant Lender Joinder Agreement to the extent the Incremental Lender is not a Lender hereunder at the time of such increase):

(x) such Incremental Commitment Increase shall mature on the Revolving Credit Maturity Date, shall bear interest at the rate applicable to the Revolving Credit Loans and shall be subject to the same terms and conditions as the Revolving Credit Loans; and

(y) the outstanding Revolving Credit Loans and Commitment Percentages of Swingline Loans and L/C Obligations will be reallocated by the Administrative Agent on the applicable Increased Amount Date among the Lenders (including the Incremental Lenders providing such Incremental Commitment Increase) in accordance with their revised Commitment Percentages, and the Lenders (including the Incremental Lenders providing such Incremental Commitment Increase) agree to make all payments and adjustments necessary to effect such reallocation and the Borrower shall pay any and all costs required pursuant to Section 5.9 in connection with such reallocation as if such reallocation were a repayment);

(E) any Incremental Lender providing an Incremental Commitment Increase shall be entitled to the same voting rights as the existing Lenders under the Revolving Credit Facility and any Extensions of Credit made in connection with each Incremental Commitment Increase shall receive proceeds of prepayments on the same basis as the other Revolving Credit Loans made hereunder;

-67-

(F) to the extent that such Incremental Commitment Increase is being provided by an Incremental Lender that is not a Lender hereunder at the time of such increase, such Incremental Commitment Increase shall be effected pursuant to one or more Lender Joinder Agreements executed and delivered by the Borrower, the Administrative Agent and the applicable Incremental Lenders (which Lender Joinder Agreement may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this Section 5.13);

(G) the Borrower shall execute and deliver additional Ship Mortgages and related perfection and other Security Documents (including, without limitation, such opinions, resolutions, certificates and other instruments related thereto) as may be reasonably requested by the Administrative Agent to (x) at all times prior to the delivery of a Perfection Trigger Notice (so long as the Springing Lien Termination Date has not occurred), the Escrow Agent and (y) on and after the delivery of a Perfection Trigger Notice (but prior to a Release Date, so long as the Springing Lien Termination Date has not occurred), the Administrative Agent, such that the aggregate orderly liquidation value (“OLV”) of all Designated Vessels (based on current appraisals from an Approved Appraiser with respect to new Designated Vessels and the appraisals from an Approved Appraiser delivered to the Administrative Agent prior to Closing Date with respect to all other Designated Vessels) that (i) other than during a Perfection Period, would be pledged or (ii) during a Perfection Period, have been pledged, as applicable, to the Administrative Agent, for the benefit of the Secured Parties, is equal to at least 1.5 times the Aggregate Commitment, after giving effect to such Incremental Commitment Increase;

(H) the Borrower shall deliver or cause to be delivered any customary legal opinions or other documents reasonably requested by Administrative Agent in connection with any such transaction.

(b) The Incremental Lenders shall be included in any determination of the Required Lenders, and the Incremental Lenders will not constitute a separate voting class for any purposes under this Agreement.

(c) On any Increased Amount Date on which any Incremental Commitment Increase becomes effective, subject to the foregoing terms and conditions, each Incremental Lender providing an Incremental Commitment Increase shall become a Lender hereunder with respect to such Incremental Commitment Increase.

SECTION 5.14 Cash Collateral. At any time that there shall exist a Defaulting Lender, following the written request of the Administrative Agent, any Issuing Lender or the Swingline Lender (with a copy to the Administrative Agent), the Borrower shall promptly (but in any event, within five (5) Business Days after the receipt of such written request) Cash Collateralize the Fronting Exposure of such Issuing Lender and/or the Swingline Lender, as applicable, with respect to such Defaulting Lender (determined after giving effect to Section 5.15(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in Dollars in an amount not less than the Minimum Collateral Amount.

-68-

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

(b) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 5.14 or Section 5.15 in respect of Letters of Credit and Swingline Loans shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of L/C Obligations and Swingline Loans (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(c) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce the Fronting Exposure of an Issuing Lender and/or the Swingline Lender, as applicable, shall no longer be required to be held as Cash Collateral pursuant to this Section 5.14 following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent, the applicable Issuing Lender and the Swingline Lender that there exists excess Cash Collateral; provided that, subject to Section 5.15, the Borrower, the applicable Issuing Lender and the Swingline Lender may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations; and provided further that to the extent that such Cash Collateral was provided by the Borrower, such Cash Collateral shall remain subject to the security interest granted pursuant to the Loan Documents.

SECTION 5.15 Defaulting Lenders.

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

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

-69-

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 12.4 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lenders or the Swingline Lender hereunder; third, to Cash Collateralize the Fronting Exposure of the Issuing Lenders and the Swingline Lender with respect to such Defaulting Lender in accordance with Section 5.14; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan or funded participation in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans and funded participations under this Agreement and (B) Cash Collateralize each Issuing Lender’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit and Swingline Loans issued by such Issuing Lender under this Agreement, in accordance with Section 5.14; sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any Issuing Lender or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (1) such payment is a payment of the principal amount of any Loans or funded participations in Letters of Credit or Swingline Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such Loans were made or the related Letters of Credit or Swingline Loans were issued at a time when the conditions set forth in Section 6.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and funded participations in Letters of Credit or Swingline Loans owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or funded participations in Letters of Credit or Swingline Loans owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in accordance with the Aggregate Commitment under the applicable Revolving Credit Facility without giving effect to Section 5.15(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 5.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(A) For Commitment Fees: No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

-70-

(B) Each Defaulting Lender shall be entitled to receive letter of credit commissions pursuant to Section 3.3 for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Commitment Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 5.14.

(C) With respect to any letter of credit commission not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to each Issuing Lender and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Lender’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Commitment Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 6.2 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, repay Swingline Loans in an amount equal to the Swingline Lenders’ Fronting Exposure and (y) second, Cash Collateralize each Issuing Lender’s Fronting Exposure in accordance with the procedures set forth in Section 5.14.

-71-

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, each Issuing Lender and the Swingline Lender agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Aggregate Commitment under the Revolving Credit Facility (without giving effect to Section 5.15(a)(iv), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

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

SECTION 10.4 Crediting of Payments and Proceeds. In the event that the Obligations have been accelerated pursuant to Section 10.2 or the Administrative Agent or any Lender has exercised any remedy set forth in this Agreement or any other Loan Document, all payments received by the Lenders upon the Facility Obligations and all net proceeds from the enforcement of the Facility Obligations shall be applied:

ARTICLE XI

THE ADMINISTRATIVE AGENT

SECTION 11.1 Appointment and Authority.

(a) Each of the Lenders and each Issuing Lender hereby irrevocably designates and appoints ▇▇▇▇▇ Fargo to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Lenders, and neither the Borrower nor any Subsidiary thereof shall, except as expressly set forth in this Article, have rights as a third party beneficiary of any of such

-115-

provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(b) The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders (including in its capacity as a potential Hedge Bank or Cash Management Bank) and each Issuing Lender hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and such Issuing Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Credit Parties to secure any of the Facility Obligations, together with such powers and discretion as are reasonably incidental thereto (including, without limitation, to enter into additional Loan Documents or supplements to existing Loan Documents on behalf of the Secured Parties). In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to this Article XI for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Security Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this Articles XI and XII (including Section 12.3, as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto.

SECTION 11.2 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

SECTION 11.3 Exculpatory Provisions.

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

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

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan

-116-

Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or Applicable Law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

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

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 12.2 and Section 10.2) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice describing such Default is given to the Administrative Agent by the Borrower, a Lender or an Issuing Lender.

(c) The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

SECTION 11.4 Reliance by the Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any certification submitted by the Borrower with respect to the confirmation of the conditions to the occurrence of a Release Date or the Springing Lien Termination Date, any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender or such Issuing Lender unless the Administrative Agent shall have received notice to the contrary from

-117-

such Lender or such Issuing Lender prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 11.5 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by the Administrative Agent. The Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub agent and to the Related Parties of the Administrative Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the Revolving Credit Facility as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non-appealable order that any direct (as opposed to indirect, special, punitive, consequential or exemplary) damages suffered by the Borrower or any of its Subsidiaries were caused by the Administrative Agent’s gross negligence or willful misconduct.

SECTION 11.6 Resignation of Administrative Agent.

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

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

(c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable), (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of

-118-

any collateral security held by the Administrative Agent on behalf of the Lenders or the Issuing Lenders under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and each Issuing Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 12.3 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent.

(d) Any resignation by ▇▇▇▇▇ Fargo (or any successor or assignee thereof) as Administrative Agent pursuant to this Section shall also constitute its resignation as an Issuing Lender and Swingline Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Lender and Swingline Lender, (b) the retiring Issuing Lender and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor Issuing Lender shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangement satisfactory to the retiring Issuing Lender to effectively assume the obligations of the retiring Issuing Lender with respect to such Letters of Credit.

SECTION 11.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and each Issuing Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and each Issuing Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 11.8 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the syndication agents, documentation agents, co-agents, bookrunners, lead managers, arrangers, lead arrangers or co-arrangers listed on the cover page or signature pages hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or an Issuing Lender hereunder.

-119-

(a) Each of the Lenders (including in its or any of its Affiliate’s capacities as a potential Hedge Bank or Cash Management Bank) irrevocably authorize the Administrative Agent, at its option and in its discretion:

(i) to release any Lien on any Collateral granted to or held by the Administrative Agent, for the ratable benefit of the Secured Parties, under any Loan Document (A) upon the termination of the Aggregate Commitment and payment in full of all Facility Obligations (other than (1) contingent indemnification obligations and (2) obligations and liabilities under Facility Cash Management Agreements or Facility Hedge Agreements) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Administrative Agent and the applicable Issuing Lender shall have been made), (B) that is sold or otherwise disposed of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document, (C) if approved, authorized or ratified in writing in accordance with Section 12.2 and (D) on each Release Date and on the Springing Lien Termination Date;

(ii) to subordinate any Lien on any Collateral granted to or held by the Administrative Agent under any Loan Document to the holder of any Permitted Lien which by operation of law or contract would have priority over the Liens securing the Obligations; and

(iii) to release any Subsidiary Guarantor from its obligations under any Loan Documents if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Subsidiary Guarantor from its obligations under the Subsidiary Guaranty Agreement pursuant to this Section 11.9. In each case as specified in this Section 11.9, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Credit Party such documents as such Credit Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Security Documents or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Subsidiary Guaranty Agreement, in each case in accordance with the terms of the Loan Documents and this Section 11.9. In the case of any such sale, transfer or disposal of any property constituting Collateral in a transaction permitted pursuant to Section 9.5, the Liens created by any of the Loan Documents on such property shall be automatically released without need for further action by any person.

-120-

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

SECTION 11.10 Facility Hedge Agreements and Facility Cash Management Agreements. No Cash Management Bank or Hedge Bank that obtains the benefits of Section 10.4 or any Collateral by virtue of the provisions hereof or of any Security Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the release or impairment of any Collateral) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents.

(c) Administrative Agent’s Office. The Administrative Agent hereby designates its office located at the address set forth above, or any subsequent office which shall have been specified for such purpose by written notice to the Borrower and Lenders, as the Administrative Agent’s Office referred to herein, to which payments due are to be made and at which Loans will be disbursed and Letters of Credit requested.

(d) change Section 5.6 or Section 10.4 in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender directly and adversely affected thereby;

-124-

(f) change any provision of this Section or reduce the percentages specified in the definitions of “Required Lenders,” or “Supermajority Lenders,” or any other provision hereof specifying the number or percentage of Lenders required to amend, waive or otherwise modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender directly affected thereby;

provided further, that (i) no amendment, waiver or consent shall, unless in writing and signed by the applicable Issuing Lender in addition to the Lenders required above, affect the rights or duties of such Issuing Lender under this Agreement or any Letter of Credit Application relating to any Letter of Credit issued or to be issued by it; (ii) no amendment, waiver or consent shall, unless in writing and signed by the Swingline Lender in addition to the Lenders required above, affect the rights or duties of the Swingline Lender under this Agreement; (iii) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Lenders required above, affect the rights or duties of the Administrative Agent under this Agreement or any other Loan Document; (iv) the Fee Letter may be amended, or rights or privileges thereunder waived, in a writing executed only by the parties thereto, (v) no amendment, waiver or consent shall, unless in writing and signed by the Supermajority Lenders, (x) affect the rights of the Supermajority Lenders to retract a Perfection Trigger Event to the extent set forth in the definition of “Perfection Trigger Event”, or (y) amend any provision of the definition of “Perfection Trigger Event” the waiver of which would require the consent of the Supermajority Lenders under clause (x) above, and (vi) the Administrative Agent and the Borrower shall be permitted to amend any provision of the Loan Documents (and such amendment shall become effective without any further action or consent of any other party to any Loan Document) if the Administrative Agent and the Borrower shall have jointly identified an obvious error or any error or omission of a technical or immaterial nature in any such provision. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that (a) the Commitment of such Lender may not be increased or extended or (b) no amendment, waiver of consent of the type set forth in Sections 12.2 (b) and (c) which would otherwise require the consent of each Lender shall be permitted, in each case, without the consent of such Defaulting Lender.

-125-

SECTION 12.3 Expenses; Indemnity.

(a) Costs and Expenses. The Borrower and any other Credit Party, jointly and severally, shall pay (i) all reasonable and documented out of pocket expenses incurred by the Administrative Agent and its Affiliates (including the reasonable fees, charges and disbursements of counsel for the Administrative Agent), in connection with the syndication of the Revolving Credit Facility, the preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable and documented out of pocket expenses incurred by the Issuing Lenders in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all documented out of pocket expenses incurred by the Administrative Agent, any Lender or any Issuing Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent, any Lender or any Issuing Lender), in connection with the enforcement or protection of its rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section, or (B) in connection with the Loans made or Letters of Credit issued hereunder, including all such out of pocket expenses incurred during any workout or restructuring in respect of such Loans or Letters of Credit.

(b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender and each Issuing Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, and shall pay or reimburse any such Indemnitee for, any and all losses, claims (including, without limitation, any Environmental Claims), damages, liabilities and related reasonable out-of-pocket expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless, each Indemnitee from, and shall pay or reimburse any such Indemnitee for, all reasonable out-of-pocket fees and disbursements for attorneys, incurred by any Indemnitee or asserted against any Indemnitee by any Person (including the Borrower or any other Credit Party), other than such Indemnitee and its Related Parties, arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto

-126-

of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby (including, without limitation, the Transactions), (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by an Issuing Lender to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property or vessel owned or operated by any Credit Party or any Subsidiary thereof, or any Environmental Claim, (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by any Credit Party or any Subsidiary thereof, and regardless of whether any Indemnitee is a party thereto, or (v) any claim (including, without limitation, any Environmental Claims), investigation, litigation or other proceeding (whether or not the Administrative Agent or any Lender is a party thereto) and the prosecution and defense thereof, arising out of or in any way connected with the Loans, this Agreement, any other Loan Document, or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee (or such Indemnitee’s officer’s employees, directors, controlled representative or controlled affiliates involved in the arrangement of this Agreement) or (y) result from a claim brought by any Credit Party or any Subsidiary thereof against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if such Credit Party or such Subsidiary has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

(c) Reimbursement by Lenders. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under clause (a) or (b) of this Section to be paid by it to the Administrative Agent (or any sub-agent thereof), an Issuing Lender, the Swingline Lender or any Related Party of any of the foregoing, then (without limiting the Borrower’s obligation to do so) each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent), such Issuing Lender, the Swingline Lender or such Related Party, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender’s share of the Total Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender); provided that with respect to such unpaid amounts owed to the Issuing Lenders or the Swingline Lender solely in its capacity as such, only the Lenders shall be required to pay such unpaid amounts, such payment to be made severally among them based on such Lenders’ Commitment Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) provided, further, that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent), the Issuing Lenders or the Swingline Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent), Issuing Lender or the Swingline Lender in connection with such capacity. The obligations of the Lenders under this clause (c) are subject to the provisions of Section 5.7.

The rights of each Lender, each Issuing Lender, the Swingline Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, such Issuing Lender, the Swingline Lender or their respective Affiliates may have. Each Lender, each Issuing Lender and the Swingline Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

-128-

SECTION 12.5 Governing Law; Jurisdiction, Etc.

(a) Governing Law. This Agreement and the other Loan Documents and any claim, controversy, dispute or cause of action (whether in contract or tort or otherwise) based upon, arising out of or relating to this Agreement or any other Loan Document (except, as to any other Loan Document, as expressly set forth therein) and the transactions contemplated hereby and thereby shall be governed by, and construed in accordance with, the law of the State of New York.

(b) Submission to Jurisdiction. Each of the parties hereto irrevocably and unconditionally submits to the non-exclusive jurisdiction of the courts of the State of New York sitting in New York County, and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by Applicable Law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document shall affect any right that the Administrative Agent, any Lender, any Issuing Lender or the Swingline Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or any other Credit Party or its properties in the courts of any jurisdiction.

(c) Waiver of Venue. Each party hereto irrevocably and unconditionally waives, to the fullest extent permitted by Applicable Law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by Applicable Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Service of Process. Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 12.1. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by Applicable Law.

SECTION 12.6 Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). IF AND TO THE EXTENT THAT THE FOREGOING WAIVER OF THE RIGHT TO A JURY TRIAL IS UNENFORCEABLE FOR ANY REASON IN SUCH FORUM, EACH OF THE PARTIES HERETO HEREBY CONSENTS TO THE

-129-

ADJUDICATION OF ALL CLAIMS PURSUANT TO JUDICIAL REFERENCE AS PROVIDED IN CALIFORNIA CODE OF CIVIL PROCEDURE SECTION 638, AND THE JUDICIAL REFEREE SHALL BE EMPOWERED TO HEAR AND DETERMINE ALL ISSUES IN SUCH REFERENCE, WHETHER FACT OR LAW. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND CONSENT AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 12.7 Reversal of Payments. To the extent any Credit Party makes a payment or payments to the Administrative Agent for the ratable benefit of the Lenders or the Administrative Agent receives any payment or proceeds of the Collateral which payments or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or proceeds repaid, the Obligations or part thereof intended to be satisfied shall be revived and continued in full force and effect as if such payment or proceeds had not been received by the Administrative Agent.

SECTION 12.8 Injunctive Relief. The Borrower recognizes that, in the event the Borrower fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, any remedy of law may prove to be inadequate relief to the Lenders. Therefore, the Borrower agrees that the Lenders, at the Lenders’ option, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

SECTION 12.9 Accounting Matters. If at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth in any Loan Document, and either the Borrower or the Required Lenders shall so request, the Administrative Agent, the Lenders and the Borrower shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Lenders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein and (ii) the Borrower shall provide to the Administrative Agent and the Lenders financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP.

SECTION 12.10 Successors and Assigns; Participations.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that neither the Borrower nor any other Credit Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender (except in connection with a transaction permitted

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in clause (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

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

-131-

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided, that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within six (6) Business Days after having received notice thereof;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender with a Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(C) the consents of the Issuing Lenders and the Swingline Lender shall be required for any assignment in respect of the Revolving Credit Facility.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 for each assignment; provided that (A) only one such fee will be payable in connection with simultaneous assignments to two or more Approved Funds by a Lender and (B) the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the Borrower’s Subsidiaries or Affiliates, (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) to any Person set forth on Schedule 12.10.

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

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested, but not funded by, the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (A) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Lenders, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (B) acquire (and fund as appropriate) its full pro rata share

-132-

of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Commitment Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 5.8, 5.9, 5.10, 5.11 and 12.3 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in Charlotte, North Carolina, a copy of each Assignment and Assumption and each Lender Joinder Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amounts of (and stated interest on) the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender (but only to the extent of entries in the Register that are applicable to such Lender), at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Issuing Lenders, the Swingline Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 12.3(c) with respect to any payments made by such Lender to its Participant(s).

-133-

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver or modification described in Section 12.2 that directly affects such Participant and could not be affected by a vote of the Required Lenders. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 5.8, 5.9, 5.10 and 5.11 (subject to the requirements and limitations therein, including the requirements of Section 5.11(f) (it being understood that the documentation required under Section 5.11(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 5.12 as if it were an assignee under paragraph (b) of this Section and (B) shall not be entitled to receive any greater payment under Sections 5.10 and 5.11, with respect to such participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.12(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.4 as though it were a Lender; provided that such Participant agrees to be subject to Section 5.6 as though it were a Lender.

(e) Participant Register. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

-134-

SECTION 12.11 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lenders and the Issuing Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential in accordance with customary practices), (b) to the extent required or requested by, or required to be disclosed to, any regulatory or similar authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by Applicable Laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies under this Agreement, under any other Loan Document or under any Facility Hedge Agreement or Facility Cash Management Agreement, or any action or proceeding relating to this Agreement, any other Loan Document or any Facility Hedge Agreement or Facility Cash Management Agreement, or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights and obligations under this Agreement, and (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (g) on a confidential basis to (i) any rating agency in connection with rating the Borrower or its Subsidiaries or the Revolving Credit Facility or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Credit Facility (it being understood that, prior to any such disclosure, such Person to whom such disclosure is to be made will be informed of the confidential nature of such Information and shall undertake to keep such Information confidential in accordance with customary practices); (h) with the written consent of the Borrower, or (i) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Lender, any Issuing Lender or any of their respective Affiliates on a non-confidential basis from a source other than the Borrower or any Affiliate of the Borrower or (k) to governmental regulatory authorities in connection with any regulatory examination of the Administrative Agent or any Lender or in accordance with the Administrative Agent’s or any Lender’s regulatory compliance policy if the Administrative Agent or such Lender deems necessary for the mitigation of claims by those authorities against the Administrative Agent or such Lender or any of its subsidiaries or affiliates. In addition, each of the Administrative Agent, the Lenders and the Issuing Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers to the Administrative Agent, the Lenders or the Issuing Lenders in connection with the administration and management of this Agreement, the other Loan Documents, the Commitments and the Extensions of Credit. For purposes of this Section, “Information” means all information received from any Credit Party or any Subsidiary thereof relating to any Credit Party or any Subsidiary thereof or any of their respective businesses, other than any such information that is publicly available to the Administrative Agent, any Lender or any Issuing Lender prior to disclosure by any Credit Party or any Subsidiary thereof other than as a result of

-135-

a breach of this Section; provided that, in the case of information received from a Credit Party or any Subsidiary thereof after the date hereof, such information is clearly identified at the time of delivery as confidential or is delivered pursuant to Section 8.1, 8.2 or 8.3 hereof and is not publically available. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Each of the Administrative Agent, the Lenders and each Issuing Lender acknowledges that (i) the Information may include material non-public information concerning the Borrower or any of its Subsidiaries, (ii) it has developed compliance procedures regarding the use of material non-public information and (iii) it is required to handle such material non-public information in accordance with applicable Law, including United States federal and state securities Laws.

All powers of attorney and other authorizations granted to the Lenders, the Administrative Agent and any Persons designated by the Administrative Agent or any Lender pursuant to any provisions of this Agreement or any of the other Loan Documents shall be deemed coupled with an interest and shall be irrevocable so long as any of the Obligations remain unpaid or unsatisfied, any of the Commitments remain in effect or the Revolving Credit Facility has not been terminated.

SECTION 12.14 Survival.

(a) All representations and warranties set forth in Article VII and all representations and warranties contained in any certificate, or any of the Loan Documents (including, but not limited to, any such representation or warranty made in or in connection with any amendment thereto) shall constitute representations and warranties made under this Agreement. All representations and warranties made under this Agreement shall be made or deemed to be made at and as of the Closing Date (except those that are expressly made as of a specific date), shall survive the Closing Date and shall not be waived by the execution and delivery of this Agreement, any investigation made by or on behalf of the Lenders or any borrowing hereunder.

(b) Notwithstanding any termination of this Agreement, the indemnities to which the Administrative Agent and the Lenders are entitled under the provisions of this Article XII, Section 5.9, Section 5.10, Section 5.11 and Section 11.3 shall continue in full force and effect and shall protect the Administrative Agent and the Lenders against events arising after such termination as well as before.

SECTION 12.17 Counterparts; Integration; Effectiveness; Electronic Execution.

(a) Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (i.e., “pdf” or “tif”) format shall be effective as delivery of a manually executed counterpart of this Agreement

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

-137-

In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower acknowledges and agrees that: (a)(i) the arranging and other services regarding this Agreement provided by the Lenders are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Lenders, on the other hand, (ii) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (iii) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (b) (i) each of the Lenders is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Affiliates, or any other Person and (ii) no Lender has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; and (c) each of the Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and no Lender has any obligation to disclose any of such interests to the Borrower or its Affiliates.

THIS LENDER-SURETY PRIORITY AGREEMENT (“Agreement”), dated , 2012, is entered into by:

▇▇▇▇▇ FARGO BANK, N.A., a national banking association, as Administrative Agent (the “Agent”) for the lenders under the Lender Credit Agreement (as defined below), and

ZURICH AMERICAN INSURANCE COMPANY and its Subsidiaries and Affiliates including, but not limited to FIDELITY AND DEPOSIT COMPANY OF MARYLAND, COLONIAL AMERICAN CASUALTY AND SURETY COMPANY, and AMERICAN GUARANTEE AND LIABILITY INSURANCE COMPANY, its successors and assigns (“Surety”).

Agent and Surety agree that all capitalized terms used in this Agreement but not defined herein shall have the meaning given such terms in the Equipment Utilization Agreement, dated June 4, 2012 (the “EUA”), which has been executed by Indemnitors and Agent.

WHEREAS Great Lakes Dredge & Dock Corporation (“Great Lakes”), Great Lakes Dredge & Dock Company, LLC, ▇▇▇▇▇ Dredging & Construction Company, Ltd., Fifty-Three Dredging Corporation, ▇▇▇▇▇▇ Marine Services Company, Great Lakes Dredge & Dock Environmental, Inc. (f/k/a Great Lakes Caribbean Dredging, Inc.), NASDI, LLC, NASDI Holdings Corporation, Yankee Environmental Services, LLC and Great Lakes Dredge & Dock (Bahamas) Ltd.(collectively, the “Indemnitors”) may provide Agent a mortgage on certain equipment of Indemnitors (the “Collateral Equipment”) and a right to attach and perfect a security interest in the Collateral Equipment, in connection with that certain Credit Agreement, dated as of June 4, 2012, among Great Lakes, certain subsidiaries of Great Lakes party thereto, as Credit Parties, Agent and the other lenders party thereto from time to time (as amended, restated, supplemented, refinanced or replaced from time to time, the “Lender Credit Agreement”); and

WHEREAS Indemnitors have provided Surety with a security interest in the Collateral Equipment (among other interests, rights and remedies) pursuant to the terms of, and as defined in, the General Agreement of Indemnity, dated September 7, 2011 (the “GIA”); and

WHEREAS Agent and Indemnitors have provided Surety a priority right to access and use the Collateral Equipment pursuant to the terms of the EUA; and

WHEREAS Agent desires for Surety to agree with Agent in advance on the priority of their respective mortgages, security interests and liens with respect to the Collateral Equipment in the event such mortgages security interests and liens are created or perfected; and

WHEREAS Surety is willing to agree to the priority of Surety’s and Agent’s respective mortgages, security interests and liens with respect to the Collateral Equipment, in exchange for Surety’s being granted a second mortgage on the Collateral Equipment.


Great Lakes Lender-Surety Priority Agreement		page 1 of 9

NOW THEREFORE, for good and valuable consideration, the sufficiency of which is hereby acknowledged, Agent and Surety agree as follows:

1. Collateral Equipment: The Collateral Equipment to which this Agreement applies is defined as the equipment listed on Exhibit A SCHEDULE OF COLLATERAL EQUIPMENT which is attached to this Agreement and incorporated herein by reference, as may be modified as provided herein. This Agreement does not apply to any other machinery, plant, equipment or other property of Indemnitors.

2. Surety Mortgage: Surety agrees that it will not perfect or file mortgages with respect to any of the Collateral Equipment, unless and until it shall have first provided Agent with 60 days written notice.

3. Priorities: Agent and Surety acknowledge and agree that the other may perfect a security interest in the Collateral Equipment. With respect to Agent’s and Surety’s mortgages, security interests and liens in the Collateral Equipment, Agent and Surety agree that as between Agent and Surety, Agent’s mortgage, security interests and liens in the Collateral Equipment shall be senior and prior in right to Surety’s mortgages, security interests and liens in the Collateral Equipment, and Surety’s mortgages, security interests and liens shall be junior to Agent’s mortgages, security interests and liens, notwithstanding the order, manner or timing of attachment or perfection of any such mortgages, security interests or liens or the validity, enforceability, perfection or unavoidability thereof or any failure by Agent or the Surety to take any action to attach or perfect such security interests or liens.

4. No Challenge: Agent and Surety agree not to institute or join in any legal action challenging the validity, enforceability, perfection or unavoidability of their respective mortgages, security interests or liens with respect to the Collateral Equipment.

5. Right to Enforce and Transfer; Release: Agent and Surety agree that the other party may take action to enforce that party’s rights and interest in the Collateral Equipment, including any rights which may result in the transfer of such Collateral Equipment to third parties, provided that a) the enforcing party provides prior written notice to the other party of the enforcing party’s foreclosure or similar disposition of any such Collateral Equipment; b) any such exercise and enforcement or other disposition by Agent of any Collateral Equipment shall be subject to and shall not interfere with Surety’s continuing rights and interests and priority access and use under and pursuant to the terms of the EUA. In the event of any transfer of such Collateral Equipment to third parties by the Agent in connection with an enforcement by the Agent or in connection with a consensual disposition and, in any such event pursuant to which the Agent shall release its mortgages, security interests or liens with respect to such Collateral Equipment, Surety shall promptly release its mortgages, security interests and liens on such Collateral Equipment, provided that Surety’s mortgages, security interests and liens shall remain on the proceeds of such Collateral Equipment, subject to the relative priorities set forth in section 3 above. Surety hereby authorizes Agent to effect such lien releases on behalf of Surety and to execute and deliver all instruments to effect such release of Surety’s mortgages, security interests and liens (which authorization being coupled with an interest, is irrevocable).

6. Modification of Exhibit A. Exhibit A may be modified by a Rider to this Agreement upon written notice by Agent to Surety at any time.


Great Lakes Lender-Surety Priority Agreement		page 2 of 9

7. Collateral Proceeds: If any Collateral proceeds (including, without limitation, insurance proceeds or distributions pursuant to any plan of reorganization or other insolvency proceeding with respect to any Indemnitor) are received by Surety with respect to the Collateral Equipment, Surety shall receive and hold such proceeds on behalf of the other party and shall promptly pay or transfer such proceeds to the other party, with any necessary endorsements. To the extent that there are any excess proceeds from the Collateral Equipment which may be held by Agent following satisfaction in full of the Indemnitor’s obligations to Agent and the lenders party to the Lender Credit Agreement and the termination of the commitments under the Lender Credit Agreement, Agent shall promptly pay or transfer such proceeds to Surety, with any necessary endorsements.

8. No Prohibition: Neither Agent nor Surety shall enter into any agreement with any Indemnitor prohibiting such Indemnitor from granting mortgages on, security interests in, or liens on, any Collateral Equipment to secure the obligations of such Indemnitor either to Agent and the lenders in connection with the Lender Credit Agreement or to Surety in connection with the GIA or the EUA.

9. No Impact on Rights and Remedies other than to the Collateral Equipment: Notwithstanding the respective priorities of security interests and liens above, nothing in this Agreement is intended to or does waive, release, limit, condition or otherwise affect the Surety’s rights and remedies under the EUA and/or the GIA, at law or in equity, other than as stated in this Agreement with respect to the Collateral Equipment, or Agent’s or any lender’s rights and remedies under and with respect to the Lender Credit Agreement with respect to the Collateral Equipment.

10. No impact on Surety’s priority use of the Collateral Equipment: Notwithstanding the respective priorities of security interests and liens above, nothing in this Agreement is intended to waive, release, limit, condition or otherwise affect the Surety’s priority access and use of the Collateral Equipment to perform Surety’s Bonded Obligations, in accordance with the EUA.

SECTION 2. Upon the occurrence of a Perfection Trigger Event, the Mortgagor will promptly cause this Mortgage to be duly filed in accordance with the provisions of Chapter 313 and will otherwise cause compliance with and satisfaction of all of the provisions of Chapter 313 in order to establish and maintain this Mortgage as a first preferred mortgage lien thereunder

SECTION 4. (a) Promptly following the occurrence of any Perfection Trigger Event and the subsequent recordation of this Mortgage in accordance with Section 2 of this Article I, the Mortgagor shall place a properly certified copy of this Mortgage on board each Vessel with its papers and will cause the same to be shown to any person having business with the Vessel which might create or imply any commitment or encumbrance whatsoever on the Vessel and shall cause a notice, reading as follows (or containing such additional information relating to any permitted mortgage that is placed on a Vessel as may be approved by the Mortgagor) printed in plain type of such size that the paragraph of reading matter shall cover a space not less than six inches wide by nine inches high, and framed, to be placed and kept prominently exhibited in the chart room and in the master’s cabin of each of the Vessels if such room and cabin are contained in the Vessel and, if not, where such notices customarily are kept for vessels of the type of the Vessel:

“NOTICE OF SHIP MORTGAGE

This vessel is owned by Great Lakes Dredge & Dock Company, LLC, a Delaware limited liability company, and is covered by a First Preferred Fleet Mortgage in favor of ▇▇▇▇▇ Fargo Bank, National Association, as Administrative Agent and trustee, under authority of Chapter 313 of Title 46 of the United States Code, as amended. Under the terms of said Mortgage, neither the owner, the master or agent of this vessel nor any other person has any right, power or authority to create, incur, or permit to be placed or imposed upon this vessel any lien whatsoever, other than liens for wages of a stevedore when employed directly by a person listed in 46 U.S.C. 31341, for wages of the crew in respect of this vessel (including wages of the master to the extent provided by 46 U.S.C. 11112), general average, salvage (including contract salvage), liens fully covered by insurance and any deductible applicable thereto, liens permitted by Section 9.2 of the Credit Agreement, and other liens incident to current operations or for repairs.”

- 3 -

(b) The Mortgagor will not create, incur, permit to be placed or imposed upon or permit to exist upon any of the Vessels or any of the proceeds of the Vessels or sums due or to become due in respect of the Vessels or in respect of insurance thereon any lien whatsoever, other than liens contemplated by the aforesaid notice. In due course and in any event within thirty (30) days after the same becomes due and payable, the Mortgagor shall pay or cause to be discharged or make adequate provision for the satisfaction or discharge of all material claims or demands with respect to the Vessels, unless such claims or demands are being contested in good faith.

SECTION 5. (a) The Mortgagor will not transfer or change the flag, change the vessel name or change the vessel number of any of the Vessels without the written consent of the Mortgagee first had and obtained, and any such written consent to any one transfer or change of flag, change in vessel name or change in vessel number shall not be construed to be a waiver of this provision with respect to any subsequent proposed transfer or change of flag, change in vessel name or change in vessel number of the same or any other Vessel.

(b) The Mortgagor will not cause or permit any of the Vessels to be operated in any manner contrary to law and the Mortgagor will not engage in any unlawful trade or violate any law or expose any of the Vessels to penalty or forfeiture, except where any such operation, engagement, violation or exposure could not reasonably be expected to have a Material Adverse Effect, and will not do, or suffer or permit to be done, anything which can or may injuriously affect in any material respect the registration, documentation, or trade endorsement of a Vessel under the laws and regulations of the United States.

(c) Without limiting in any way the right of the Mortgagee to decline to grant any written consent described in Section 5(a) or to condition any such written consent on other conditions, it is expressly understood and agreed that the Mortgagee shall not grant any such written consent unless either: (i) the Mortgagee is satisfied that all actions necessary or desirable have been taken so that after giving effect to the proposed transfer or change the Mortgagee will, upon the occurrence of any Perfection Trigger Event, have a valid and enforceable first lien on the Vessels which are the subject hereof providing rights (including practically realizable enforcement rights) and benefits to the Mortgagee with respect to such Vessels at least as favorable to the Mortgagee as those granted to the Mortgagee with respect thereto by this Mortgage or (ii) the Mortgagor substitutes for such Vessels as collateral under this Mortgage other vessels owned by the Mortgagor (including all appurtenances thereunto appertaining or belonging and any and all additions, improvements and replacements thereto) such that, after giving effect to any such substitution, the aggregate orderly liquidation value of all vessels subject to the Ship Mortgages is equal to at least: (x) prior to the first Incremental Commitment Increase, $260,000,000, and (y) on and after each Incremental Commitment Increase, 1.5 times the Aggregate Commitment, immediately after giving effect to such Incremental Commitment Increase.

SECTION 6. (a) From and after any Perfection Trigger Event, in the event of an actual, constructive or compromised total loss of any Vessel, such loss shall not be adjusted or compromised without the prior written consent of the Mortgagee, and all insurance or other payments for such shall, unless the Mortgagor is entitled to reinvest such payments in accordance with Section 2.4 of the Credit Agreement and does elect to so reinvest, be paid to the

- 4 -

Mortgagee and applied by the Mortgagee as follows: first, to any costs or expenses of the Mortgagee in connection with collecting such payment; second, to the payment of the Secured Obligations; third, to the payment of all other secured indebtedness, if any; and fourth, any surplus thereafter remaining, to the Mortgagor, its successors and assigns or to whomever may be lawfully entitled to receive the same.

(b) In the event that any claim or lien is asserted against any Vessel for loss, damage or expense which is covered by insurance required hereunder, and it is necessary for the Mortgagor to obtain a bond or supply other security to prevent arrest of the Vessel or to release the Vessel from arrest on account of such claim or lien, the Mortgagee, on request of the Mortgagor or its agent, may, in the sole discretion of the Mortgagee, assign to any person, firm or corporation executing a surety or guarantee bond or other agreement to save or release the Vessel from such arrest, all right, title and interest of the Mortgagee in and to said insurance covering said loss, damage or expense, as collateral security to indemnify against liability under said bond or other agreement. In any such event, Mortgagor shall promptly notify Mortgagee in writing of any such arrest or threatened arrest and, within thirty (30) days, cause such Vessel to be released by posting security or otherwise.

(c) If requested by the Mortgagee at any time and from time to time, the Mortgagor will deliver to the Mortgagee copies of all cover notes, binders, policies and certificates of entry in protection and indemnity associations, and all endorsements and riders amendatory thereof, in respect of insurance maintained in connection with the Vessels.

(d) The Mortgagor agrees that it will not do or permit or willingly allow to be done any act by which any insurance required by the terms of this Mortgage may be suspended, impaired or cancelled, and that it will not permit or allow any Vessel to undertake any voyage or run any risk or transport any cargo or passengers which may not be permitted by the policies in force, without having previously insured the Vessel by additional coverage extending to such voyages, risks, passengers or cargoes.

SECTION 7. The Mortgagor shall promptly notify the Mortgagee of the actual or constructive total loss of a Vessel or the agreed or compromised total loss of a Vessel, or the arrest, capture, condemnation, confiscation, registration, seizure or forfeiture of a Vessel.

SECTION 8. The Mortgagor represents and warrants that it is and will at all times remain a citizen of the United States within the meaning of Section 2 of the Shipping ▇▇▇, ▇▇▇▇, and pursuant to 46 U.S.C. Section 12103(b) and 46 U.S.C. Section 50501, as amended, entitled to own, document and operate vessels in the coastwise trade under the laws of the United States.

(d) A failure in the due and punctual observance and performance by the Mortgagor of any provision of this Mortgage which shall continue without being cured by the Mortgagor for a period of thirty (30) days after written notice thereof shall have been given by the Mortgagee to the Mortgagor; or

(e) The Mortgagor shall abandon any Vessel, other than in connection with an insured actual, constructive or compromised total loss of such Vessel.

SECTION 2. If any Default shall occur and be continuing uncured, then at any time thereafter while such Default shall remain uncured, the Mortgagee shall have the right to exercise any or all of the remedies resulting therefrom under the terms of the Credit Agreement and, if a Perfection Trigger Event shall have occurred and be continuing, any or all of the following remedies:

(a) Exercise all of the rights and remedies in foreclosure and otherwise given to mortgagees by Chapter 313 or by any other provisions of applicable law;

(c) The Mortgagee may take and enter into possession of any or all of the Vessels, at any time, wherever the same may be, without legal process and without being responsible for loss or damage, and the Mortgagor or other person in possession forthwith upon demand of the Mortgagee shall surrender to the Mortgagee possession of each such Vessel demanded and, once in possession of any such Vessel, the Mortgagee may, without being responsible for loss or damage, hold, lay up, lease, charter, operate or otherwise use the Vessel for such time and upon such terms as it may deem to be for its best advantage, and demand, collect and retain all hire, freights, earnings, issues, revenues, income, profits, return premiums, salvage awards or recoveries, recoveries in general average, and all other sums due or to become due in respect of the Vessel or in respect of any insurance thereon from any person whomsoever, accounting only for the net profits, if any, arising from such use of the Vessel and charging upon all receipts from the use of such Vessel or from the sale thereof by court proceedings or pursuant to subsection (d) of this Section 2, all costs, expenses, charges, damages or losses by reason of such use; and if at any time the Mortgagee shall avail itself of the right herein given to it to take

- 6 -

any or all of the Vessels, the Mortgagee shall have the right to dock each Vessel taken, for a reasonable time at any dock, pier or other premises of any person in possession of such Vessel without charge, or to dock any or all of the Vessels taken at any other place at the cost and expense of the Mortgagor; and

(d) The Mortgagee may take and enter into possession of any or all of the Vessels, at any time, wherever the same may be, without legal process, and, once in possession of each of the Vessels taken, if it seems desirable to the Mortgagee and without being responsible for loss or damage, sell each such Vessel, at any place and at such time as the Mortgagee may specify and in such manner as the Mortgagee may deem advisable, free from any claim by the Mortgagor in admiralty, in equity, at law or by statute, after first giving notice of the time and place of sale with a general description of the property in the following manner:

(i)

By publishing such notice for ten (10) consecutive business days in a daily newspaper of general circulation published in New York City;

(ii)

If the place of sale should not be New York City, then also by publication of a similar notice for a similar period of time in a daily newspaper, if any, published at the place of sale; and

(iii)

By mailing, by registered or certified mail, a similar notice to the Mortgagor on the day of first publication and at least thirty (30) days prior to the date fixed for sale.

The Mortgagee may adjourn any such sale from time to time by announcement at the time and place appointed for such sale or for such adjourned sale, and without further notice or publication the Mortgagee may make any such sale at the time and place to which the same shall be so adjourned. Any such sale may be conducted without bringing the Vessels subject to such sale to the place designated for such sale and in such manner as the Mortgagee may deem to be for its best advantage.

SECTION 3. Any sale of any or all of the Vessels made pursuant to this Mortgage, whether under the power of sale hereby granted or any judicial proceedings, shall operate to divest all right, title and interest of any nature whatsoever of the Mortgagor therein and thereto, and shall bar the Mortgagor, its successors and assigns, and all persons claiming by, through or under them from claiming any interest in or with respect to each Vessel sold. No purchaser shall be bound to inquire whether notice has been given, or whether any Default has occurred, or as to the propriety of the sale, or as to the application of the proceeds thereof. At any such sale, the Mortgagee may bid for and purchase such property and upon compliance with the terms of sale may hold, retain and dispose of such property without further accountability therefor.

SECTION 4. Provided that a Perfection Trigger Event shall have occurred, the Mortgagee is hereby appointed attorney-in-fact of the Mortgagor in the name of the Mortgagor at any time following the occurrence and during the continuation of any Default, to execute and deliver to any purchaser aforesaid, and is hereby vested with full power and authority to make, in the name and in behalf of the Mortgagor, a good conveyance of the title to each Vessel sold. In

- 7 -

the event of any sale of a Vessel, under any power herein contained, the Mortgagor will, if and when required by the Mortgagee, execute such form of conveyance of such Vessel, as the Mortgagee may direct or approve. The Mortgagor hereby consents to the appointment of a consent keeper or substitute custodian by the Mortgagee with the costs thereof to be a cost of the sale to be paid from the proceeds of the sale or by the Mortgagor and, therefore, secured by this Mortgage as additional Secured Obligations.

SECTION 5. Without limiting in any way the provisions of Section 6 of Article I hereof, the Mortgagee is hereby appointed attorney-in-fact of the Mortgagor in the name of the Mortgagor at any time following the occurrence and during the continuation of any Default and provided that a Perfection Trigger Event shall have occurred, to demand, collect, receive, compromise and ▇▇▇ for, so far as may be permitted by law, all freight, hire, earnings, issues, revenues, income and profits of any or all of the Vessels and all amounts due from underwriters under any insurance thereon as payment of losses or as return premiums or otherwise, salvage awards and recoveries, recoveries in general average or otherwise, and all other sums due or to become due at the time of the happening of any Default in respect of such Vessel or Vessels, or in respect of any insurance thereon, from any person whomsoever, and to make, give and execute in the name of the Mortgagor, acquittances, receipts, releases or other discharges for the same, whether under seal or otherwise, and to endorse and accept in the name of the Mortgagor all checks, notes, drafts, warrants, agreements and other instruments in writing with respect to the foregoing.

SECTION 6. The Mortgagee may, whenever any right to enter and take possession of any or all of the Vessels accrues to the Mortgagee hereunder, require the Mortgagor to deliver, and the Mortgagor shall on demand, at its own cost and expense, deliver, to the Mortgagee each Vessel as demanded. If any legal proceedings shall be taken to enforce any right under this Mortgage, the Mortgagee shall be entitled as a matter of right to the appointment of a receiver of any or all of the Vessels and of the freights, hire, earnings, issues, revenues, income and profits due or to become due and arising from the operation thereof.

SECTION 7. Provided that a Perfection Trigger Event shall have occurred, upon the occurrence and during the continuation of a Default, the Mortgagor authorizes and empowers the Mortgagee or its appointees or any of them to appear in the name of the Mortgagor, its successors and assigns, in any court of any country or nation of the world where a suit is pending against any of the Vessels because of or on account of any alleged lien against such Vessel from which such Vessel has not been released other than the lien of this Mortgage, and to take such proceedings as to her as may seem proper towards the defense of such suit and the purchase or discharge of such lien, and all expenditures made or incurred by it for the purpose of such defense or purchase or discharge shall be a debt due from the Mortgagor, its successors and assigns, to the Mortgagee, and shall be secured by the lien of this Mortgage in like manner and extent as if the amount and description thereof were written herein.

SECTION 8. Each and every power and remedy herein given to the Mortgagee shall be cumulative and shall be in addition to every other power and remedy herein given or now or hereafter existing at law, in equity, in admiralty or by statute, and each and every power and remedy whether herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the

- 8 -

beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other power or remedy. No delay or omission by the Mortgagee in the exercise of any right or power or in the pursuance of any remedy accruing upon any Default shall impair any such right, power or remedy or be construed to be a waiver of any such Default or to be an acquiescence therein; nor shall the acceptance by the Mortgagee of any security or of any payment of or on account of the amounts due in respect of the Secured Obligations after any Default or of any payment on account of any past Default be construed to be a waiver of any right to take advantage of any future Default or of any past Default not completely cured thereby.

SECTION 9. If at any time after a Default and prior to the actual sale of any of the Vessels by the Mortgagee or prior to any foreclosure proceedings, the Mortgagor offers to cure completely all Defaults and to pay all expenses, advances and damages to the Mortgagee consequent on such Defaults, then the Mortgagee shall accept such offer, cure and payment and restore the Mortgagor to its former position, but such action shall not affect any subsequent Default or impair any rights consequent thereon.

SECTION 10. In case the Mortgagee shall have proceeded to enforce any right, power or remedy under this Mortgage by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Mortgagee, then and in every such case the Mortgagor and the Mortgagee shall be restored to their former positions and rights hereunder with respect to the property subject or intended to be subject to this Mortgage, and all rights, remedies and powers of the Mortgagee shall continue as if no such proceedings had been taken.

SECTION 11. Following the occurrence of a Perfection Trigger Event, the proceeds of any sale of any or all of the Vessels, earnings of any charter operation or other use of any or all of the Vessels by the Mortgagee under any of the powers herein specified, and any and all other moneys received by the Mortgagee pursuant to or under the terms of this Mortgage or in any proceedings hereunder, the application of which has not elsewhere herein, in the Credit Agreement or in the Intercreditor Agreement been specifically provided for, shall be applied or held as follows:

First:

Applied to the payment of all reasonable out-of-pocket expenses and charges, including the expenses of any sale, the expenses of any retaking, attorneys’ fees, court costs, and any other expenses or advances made or incurred by the Mortgagee in the protection of its rights or the pursuance of its remedies hereunder;

Second:

Applied to the payment of any damages or injuries sustained by the Mortgagee occasioned by noncompliance by the Mortgagor with the terms and provisions of this Mortgage and to furnish indemnity in the proper amount against any other liens or other encumbrances which have or may have priority over those established by this Mortgage;

Third:

Applied to the payment of the Secured Obligations in such priority as the Mortgagee may elect;
