INTERNATIONAL LETTER OF CREDIT AGREEMENT

This International Letter of Credit Agreement is entered into as of September 29, 2006 among GREAT LAKES DREDGE & DOCK CORPORATION, a Delaware corporation, the Guarantors from time to time party hereto and WELLS FARGO HSBC TRADE BANK, N.A. (together with its successors and assigns, the “Bank”).

The Borrower has requested that the Bank provide an international letter of credit facility, and the Bank is willing to do so on and subject to the terms and conditions set forth herein.

In consideration of the mutual covenants herein contained, the parties hereto covenant and agree as follows:

ARTICLE I.
CERTAIN DEFINITIONS AND OTHER INTERPRETIVE PROVISIONS.

1.1 Definitions. Capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings given to them in Exhibit A to this Agreement.

1.2 Other Interpretive Provisions. With reference to this Agreement and each other International Loan Document, unless otherwise specified herein or in such other International Loan Document:

(a) The definitions of terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise, (i) any definition of or reference to any agreement, instrument or other document (including any Organization Document) shall be construed as referring to such agreement, instrument or other document as from time to time amended, restated, supplemented or otherwise modified (subject to any restrictions on such amendments, restatements, supplements or modifications set forth herein or in any other International Loan Document), (ii) any reference herein to any Person shall be construed to include such Person’s successors and assigns, (iii) the words “herein,” “hereof” and “hereunder” and words of similar import when used in any International Loan Document, shall be construed to refer to such International Loan Document in its entirety and not to any particular provision thereof, (iv) all references in an International Loan Document to Articles, Sections, Exhibits and Schedules shall be construed to refer to Articles and Sections of, and Exhibits and Schedules to, the International Loan Document in which such references appear, (v) any reference to any law shall include all statutory and regulatory provisions consolidating, amending, replacing or interpreting such law and any reference to any law or regulation shall, unless otherwise specified, refer to such law or regulation as amended, modified or supplemented from time to time, and (vi) the words “asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties, including cash, securities, accounts and contract rights.

(b) In the computation of periods of time from a specified date to a later specified date, the word “from” means “from and including;” the words “to” and “until” each mean “to but excluding;” and the word “through” means “to and including.”

(c) Section headings herein and in the other International Loan Documents are included for convenience of reference only and shall not affect the interpretation of this Agreement or any other International Loan Document.

1.3 Accounting Terms.

(a) All accounting terms not specifically defined herein shall be construed in accordance with GAAP. The Borrower shall maintain a system of accounting established and administered in accordance with sound business practices to permit preparation of financial statements in conformity with GAAP (except as may be otherwise required pursuant to Section 1.3(b)), and each of the financial statements described below shall be prepared from such system and records.

(b) Except as otherwise provided herein, if any changes in accounting principles from those used in the preparation of the most recent financial statements referred to in Section 8.1 are hereafter required or permitted by the rules, regulations, pronouncements and opinions of the Financial Accounting Standards Board of the American Institute of Certified Public Accountants (or successors thereto or agencies with similar functions) and are adopted by the Borrower with the agreement of its independent certified public accountants and such changes result in a change in the method of calculation of any of the financial covenants, standards or terms found in Section 9.5 or in the related definitions of terms used therein, the parties hereto agree, subject to Section 11.15, to enter into negotiations in order to amend such provisions so as to reflect equitably such changes with the desired result that the criteria for evaluating the Borrower’s financial condition shall be the same after such changes as if such changes had not been made, provided that, subject to Section 11.15, no change in GAAP that would affect the method of calculation of any of the financial covenants, standards or terms shall be given effect in such calculations until such provisions are amended, in a manner satisfactory to the Bank, so as to reflect such change in accounting principles.

1.4 Times of Day. Unless otherwise specified, all references herein to times of day shall be references to Central time (daylight or standard, as applicable).

ARTICLE II.
LETTERS OF CREDIT.

2.1 Commitment.

(a) Upon the terms and conditions and relying upon the representations and warranties herein set forth, the Bank agrees to issue standby Letters of Credit for the account of the Borrower up to an aggregate face amount not exceeding at any one time outstanding the lesser of (i) $20,000,000.00 (such amount, as it may be reduced from time to time pursuant to Section 3.6, being the Bank’s “Commitment”) or (ii) the International Borrowing Base.

(b) The Borrower shall execute and deliver to the Bank, to evidence its reimbursement obligations in respect of Letters of Credit, a Note which shall be (i) dated of even date herewith; (ii) in the principal amount of the Commitment; and (iii) in substantially the form attached hereto as Exhibit B, with the blanks appropriately completed.

2.2 International Borrowing Base.

(a) As soon as available, and in any event by 11 a.m. (Central time) each Wednesday (or, if Wednesday is not a Business Day, then on the following Business Day), the Borrower shall furnish the Bank an international borrowing base detailed scheduled report in the form of Exhibit C, which is dated as of the last Business Day of the previous calendar week (the “Weekly International Borrowing Base Certificate”); provided, however, in order to receive Credit Accommodations hereunder, the Borrower shall have delivered a Weekly International Borrowing Base Certificate at least within the past seven (7) calendar days. The Bank may, on demand, inspect the documentation supporting any Weekly International Borrowing Base Certificate. With respect to the Weekly International Borrowing Base Certificate delivered for the fourth week of every calendar month, such Weekly International Borrowing Base Certificate shall include (i) a list of the Eligible Export-Related Accounts Receivable and (ii) a list of Export Orders that are included in the International Borrowing Base, as at the end of the preceding month, such list to be in such form and containing such information and detail as the Bank may reasonably request, and as is satisfactory to the Bank, to comply with the requirements of the Ex-Im Bank Guaranty, including, without limiting the generality of the foregoing, as to Eligible Export-Related Accounts Receivable, aging thereof in the customary manner. The inclusion of any receivable in the Weekly International Borrowing Base Certificate shall constitute a representation and warranty by the Borrower that such receivable is an Eligible Export-Related Accounts Receivable.

(b) Two Business Days after the receipt of any such Weekly International Borrowing Base Certificate (unless the Bank prior to such date has notified the Borrower in writing of its determination of a different International Borrowing Base) the International Borrowing Base amount stated in any such Weekly International Borrowing Base Certificate shall automatically be deemed the International Borrowing Base amount until the earlier of (i) the date of the next determination or (ii) the date the Bank notifies the Borrower in writing of its determination of a different International Borrowing Base and the basis for such determination. The date of any such notification (if any) by the Bank is herein called a “Determination Date” and any increase or reduction in the International Borrowing Base by the Bank shall be effective as of such date. Each determination of the International Borrowing Base shall be made by the Bank in its reasonable business judgment, based on the most recent Weekly International Borrowing Base Certificate furnished by the Borrower and other information available to the Bank.

2.3 Letters of Credit.

(a) Subject to and upon the terms and conditions herein set forth, including, without limitation, the applicable terms and conditions set forth in Article VII hereof, the Bank agrees that it will, following its receipt of a Letter of Credit Request, issue or cause to be issued for the account of the Borrower one or more irrevocable standby letters of credit which can be drawn down by a Buyer only if the Borrower, any Guarantor or an Eligible Joint Venture fails to perform any of its obligations under an Export Order (each a “Letter of Credit” and collectively, the “Letters of Credit”); provided that the Bank shall be under no obligation to issue or cause to be issued any Letter of Credit if at the time of such issuance:

(i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain the Bank or Wells Fargo from issuing such Letter of Credit or any requirement of law applicable to the Bank or Wells Fargo or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Bank or Wells Fargo shall prohibit, or request that the Bank or Wells Fargo refrain from, the issuance of letters of credit generally; or

(ii) subject to any Cover requirements set forth in Section 10.3 of this Agreement, (x) 25% of the Stated Amount of such Letter of Credit plus (y) 25% of the aggregate Stated Amount of all outstanding Letters of Credit plus (z) 100% of the aggregate Unpaid Drawings then outstanding (after giving effect to all Unpaid Drawings reimbursed prior to or concurrently with the issuance of such Letter of Credit) exceeds the International Borrowing Base then in effect; or

(iii) if the Stated Amount of such Letter of Credit plus all Letter of Credit Outstandings (after giving effect to all Unpaid Drawings reimbursed prior to or concurrently with the issuance of such Letter of Credit) exceeds the Commitment; or

(iv) unless the Bank and Ex-Im Bank shall give their prior written consent in their sole discretion, the expiry date of such Letter of Credit is later than 12 months from the date of issuance of such Letter of Credit; provided however, the Bank may issue or cause to be issued the Diyaar Project Letter of Credit so long as the Diyaar Project Letter of Credit shall have an expiry date of not later than the lesser of (a) 27 months from the date of issuance of such Diyaar Project Letter of Credit and (b) the number of months from Closing Date to the Final Disbursement Date.

(b) Notwithstanding the foregoing, (i) the Bank may not issue or cause to be issued during the final sixty (60) days of the term of this Agreement any Letters of Credit which expire after the Maturity Date unless the Bank either has decided to renew this Agreement or has obtained the prior written approval of Ex-Im Bank and (ii) any Letter of Credit that shall have an expiration date after the Maturity Date shall be subject to Cover, such Cover to be delivered to the Bank thirty (30) days prior to the Maturity Date.

(c) The Borrower acknowledges that the Bank will be liable to Wells Fargo for reimbursement of any and all draws under Letters of Credit issued by Wells Fargo and for all other amounts required to be paid under the applicable Application and the Standby Letter of Credit Agreement. Accordingly, the Borrower agrees to pay to the Bank any and all amounts required to be paid under the applicable Application and the Standby Letter of Credit Agreement, when and as required to be paid thereby.

(d) From and after the Initial Date, all Existing Letters of Credit shall be deemed to have been issued pursuant hereto, and shall be subject to and governed by the terms and conditions hereof.

2.4 Letter of Credit Requests.

(a) Whenever the Borrower desires that a Letter of Credit be issued for its account or that an existing expiry date shall be extended, the Borrower shall deliver to the Bank its prior written request therefore not later than 12:00 noon (Central time) on at least the second Business Day prior to the requested issuance or extension date, as the case may be. Each such request shall be in the form of Exhibit E attached hereto executed by the Borrower or such other form (including electronic requests) satisfactory to the Bank and Wells Fargo in their sole discretion (together with the Application, a “Letter of Credit Request”) and, in the case of the issuance of any Letter of Credit, shall be accompanied by an Application therefor, completed to the satisfaction of the Bank and Wells Fargo, and such other certificates, documents and other papers and information as the Bank and Wells Fargo may reasonably request. Each Letter of Credit shall be denominated in Dollars or in an Approved Currency, shall expire no later than the date specified in Section 2.3, shall not be in an amount greater than is permitted under Section 2.3(a) and shall be in such form as may be approved from time to time by the Bank, Wells Fargo and the Borrower.

(b) The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the Borrower that such Letter of Credit may be issued in accordance with, and will not violate the requirements of Section 2.3(a) and Article VII of this Agreement. Upon its issuance of any Letter of Credit or the extension of the existing expiry date of any Letter of Credit, as the case may be, the Bank shall promptly notify the Borrower of such issuance or extension, which notice shall be accompanied by a copy of the Letter of Credit actually issued or a copy of any amendment extending the existing expiry date of any Letter of Credit, as the case may be.

2.5 Agreement to Repay Letter of Credit Drawings.

(a) Upon the receipt by the Bank of notice of any Drawing from a beneficiary under a Letter of Credit, the Bank promptly will provide the Borrower with telecopy notice thereof. The Borrower hereby agrees to reimburse the Bank by making payment to the Bank in immediately available funds at the Payment Office, for any payment made by the Bank under any Letter of Credit issued by it or Wells Fargo (each such amount so paid until reimbursed, an “Unpaid Drawing”) on the date of such payment, provided that if the Borrower shall have received notice of any Drawing later than 11:00 a.m. (Central

time) on any Business Day, then the Borrower shall make such payment not later than 11:00 a.m. (Central time) on the immediately following Business Day, together with interest on the amount so paid by the Bank at the rate specified herein, to the extent not reimbursed prior to 2:00 p.m. (Central time) on the date of such payment, from and including the date paid but excluding the date reimbursement is made as provided above, such interest to be payable ON DEMAND.

(b) The Borrower’s obligations under this Section 2.5 to reimburse the Bank with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances (except as provided below with respect to the gross negligence, bad faith or willful misconduct of the Bank or Wells Fargo) and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the Bank or Wells Fargo, including any defense based upon the failure of any drawing under a Letter of Credit (each a “Drawing”) to conform to the terms of the Letter of Credit (other than a defense based upon the gross negligence, bad faith or willful misconduct of the Bank or Wells Fargo in determining whether such Drawing conforms to the terms of the Letter of Credit) or any non-application or misapplication by the beneficiary of the proceeds of such Drawing, including any of the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the other International Loan Documents;

(ii) the existence of any claim, setoff, defense or other right which the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Bank, Wells Fargo, or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower or any other Person and the beneficiary named in any such Letter of Credit);

(iii) any draft, certificate or any other document presented under the Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

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

(v) the occurrence of any Default or Event of Default; or

(vi) any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Borrower;

provided that none of the foregoing is attributable to the gross negligence, bad faith or willful misconduct of the Bank or Wells Fargo.

(c) The Borrower also agrees with the Bank that, in the absence of gross negligence, bad faith or willful misconduct of the Bank or Wells Fargo, the Bank shall not be responsible for, and the Borrower’s reimbursement obligations under Section 2.5(a) 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 the Borrower or any other Person and the 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 or any other Person against any beneficiary of such Letter of Credit or any such transferee.

(d) Neither the Bank nor Wells Fargo shall 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 the Bank’s or Wells Fargo’s gross negligence, bad faith or willful misconduct. The Borrower agrees that any action taken or omitted by the Bank or Wells Fargo under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence, bad faith or willful misconduct and in accordance with the standards of care specified in the Uniform Customs and Practice for Documentary Credits (1994 Revision), International Chamber of Commerce, Publication No. 500 (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Bank) and, to the extent not inconsistent therewith, the Uniform Commercial Code of the State of New York, shall not result in any liability of the Bank or Wells Fargo to the Borrower or any other Person. IT IS THE INTENT OF THE PARTIES HERETO THAT NEITHER THE BANK NOR WELLS FARGO SHALL HAVE ANY LIABILITY UNDER THIS SECTION 2.5 FOR THE ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE OF THE BANK OR WELLS FARGO.

2.6 Conflict Between Applications and Agreement. To the extent that any provision of any Application related to any Letter of Credit or any provision of the Standby Letter of Credit Agreement is inconsistent with the provisions of this Agreement, the provisions of this Agreement shall control.

2.7 Increased Costs; Increased Capital.

(a) If the Bank determines that compliance with any law or regulation or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) issued after the Closing Date affects or would affect the amount of capital required or expected to be maintained by the Bank or any corporation controlling the Bank and that the amount of such capital is increased by or based upon the existence of the Bank’s Commitment hereunder and other commitments of this type, then, within fifteen (15) Business Days after written demand by the Bank, the Borrower shall pay to the Bank, from time to time as specified by the Bank, additional amounts sufficient to compensate the Bank or such corporation for such increase. A certificate as to such amounts, showing a calculation of such amounts in reasonable detail, submitted to the Borrower by the Bank shall be presumptive evidence of such amounts.

(b) Anything in this Section notwithstanding: (i) the Borrower shall not be required to pay to the Bank reimbursement or indemnification with regard to any costs or expenses described in this Section, unless the Bank notifies the Borrower in writing of such costs or expenses within ninety (90) days after the date the Bank obtained knowledge of the circumstances that would cause the Borrower to pay such additional amounts; and (ii) the Bank shall not be permitted to pass through to the Borrower charges and costs under this Section on a discriminatory basis (i.e., which are not also passed through by the Bank to other customers of the Bank similarly situated where such customer is subject to documents providing for such pass through).

2.8 Default Rate. Notwithstanding anything set forth herein to the contrary if any Unpaid Drawing is not paid when due, all outstanding Obligations shall bear interest at a fluctuating rate per annum equal to the Default Rate, which interest shall be due and payable ON DEMAND.

2.9 Facility Subject to Ex-Im Bank Rules. The Borrower acknowledges that the Bank is willing to make its Commitment available to the Borrower because Ex-Im Bank is willing to guaranty payment of a significant portion of the Obligations pursuant to the Ex-Im Bank Guaranty. Accordingly, in the event of any inconsistency among the International Loan Documents and the Ex-Im Bank Guaranty, the Borrower Agreement, the Fast Track Agreement, the Fast Track Borrower Supplement and the rules and regulations of Ex-Im Bank governing the Working Capital Guaranty Program, the provision that is the more stringent on the Borrower shall control and compliance with any such applicable rule or regulation shall constitute an additional covenant of the Borrower incorporated herein by reference; provided, however, that the following provisions shall be deemed to be waived by the terms of this Agreement: (1) Fast Track Lender Agreement Section 2(e)(ii)(a) with respect to the requirement that the Borrower provide the Bank with a Lien on the domestic revolving loan collateral under the Domestic Credit Agreement; (2) Section 1.01 of the Borrower Agreement and the Ex-Im Bank Guaranty with respect to the definition of Eligible Export-Related Accounts Receivable regarding (i) Accounts Receivable owned by the Eligible Joint Ventures being included in the definition of Eligible Export-Related Accounts Receivable and (ii) affiliate receivables being included in the definition of Eligible Export-Related Accounts Receivable; (3) Section 4.12(b) of the Ex-Im Bank Guaranty with respect to the length of the term of certain letters of credit longer than 12 months; (4) Section 4.02 of the Ex-Im Bank Guaranty, as amended by the Fast Track Lender Agreement, with respect to the requirement that the Bank perfect its security interest in Export-Related Inventory; (5) Section 4.02(a) of the Ex-Im Bank Guaranty, as amended by the Fast Track Lender Agreement, with respect to the collateral securing the Domestic Credit Agreement that will not secure the Obligations; (6) Section 7 of the Fast Track Agreement, Section 2.07(c) of the Borrower Agreement, as amended by the Fast Track Borrower Supplement and Section 2.08(a) of the Borrower Agreement, as amended by the Fast Track Borrower Supplement with respect to the payment of all funds received in payment of the Excluded Export-Related Accounts Receivable into a lockbox and/or the Cash Collateral Account; (7) Section 2.19 of the Borrower Agreement with respect to naming the Bank as loss payee or mortgagee on its property insurance; and (8) Section 2.22 of the Borrower Agreement with respect to the consummation of the Aldabra Transactions. The Borrower and the Bank hereby acknowledge that Holdings and the Persons that own 20% or more of the ownership of Holdings are controlled by venture capital

firms, private equity firms or other investment groups and are therefore not required to guaranty this Agreement.

2.10 Currency Equivalents. For all purposes of this Agreement, (i) the equivalent in Dollars of any Approved Currency shall be determined by using the quoted spot rate at which Wells Fargo offers to exchange Dollars for such Approved Currency two Business Days prior to the date on which such equivalent is to be determined and (ii) the equivalent in any Approved Currency of Dollars shall be determined by using the quoted spot rate at which Wells Fargo offers to exchange such Approved Currency for Dollars two Business Days prior to the date on which such equivalent is to be determined. The equivalent in Dollars of each Letter of Credit made in an Approved Currency shall be recalculated hereunder on each date that it shall be necessary or desirable by any party to determine the amount of the Commitment, the Unpaid Drawings, the Letter of Credit Obligations, the Letter of Credit Outstandings, the Obligations or the face amount of any Letter of Credit on such date.

ARTICLE III.
CASH COLLATERAL, PREPAYMENTS AND OTHER PAYMENTS.

3.1 Deposit of Cash Collateral and Required Prepayments.

(a) The Borrower agrees that if at any time the Borrower or the Bank determines that (x) 25% of the aggregate Stated Amount of all outstanding Letters of Credit plus (z) 100% of the aggregate Unpaid Drawings then outstanding exceeds the International Borrowing Base, the Borrower will, within five Business Days after request from the Bank or actual knowledge thereof, (i) deliver to the Bank cash collateral in an amount equal to such excess, which shall be held by the Bank to the extent and until such excess is eliminated or (ii) furnish additional security to the Bank, in form and amount satisfactory to the Bank and Ex-Im Bank.

(b) The Borrower agrees that if at any time the aggregate principal amount of the Letter of Credit Outstandings exceeds the amount of the Commitment, the Borrower shall immediately deliver to the Bank cash collateral in an amount equal to such excess, which, subject to Section 3.1(c) below, shall be held by the Bank to the extent and until such excess is eliminated.

(c) Cash collateral provided to the Bank pursuant to Section 3.1(a) and (b) above shall be first applied by the Bank to the Unpaid Drawings, if any, and the remainder to be held by the Bank in a collateral account.

3.2 [RESERVED].

3.3 Place of Payment or Prepayment. All payments and prepayments of the Obligations made in accordance with the provisions of this Agreement or of the Note, including, without limitation, fees, reimbursements or interest, shall, subject to Section 2.5(a), be made to the Bank at the Payment Office no later than 2:00 p.m. (Central time) on the date when due, in immediately available funds.

3.4 Prepayment Premium or Penalty. Each prepayment pursuant to Section 3.1 shall be without premium or penalty.

3.5 Taxes. Unless required by law, all payments (whether of principal, interest, reimbursements or otherwise) under this Agreement or on the Note shall be made by the Borrower without set-off or counterclaim and shall be made free and clear of and without deduction for any present or future tax, levy, impost or any other charge, if any, of any nature whatsoever now or hereafter imposed by any taxing authority, but excluding taxes imposed on or measured by the Bank’s net income (including branch profits taxes) and franchise taxes imposed on the Bank (each non-excluded tax, levy, impost or charge, a “Tax”). If the making of such payments is prohibited by law unless such Tax is deducted or withheld therefrom, the Borrower shall pay to the Bank, on the date of each such payment, such additional amounts as may be necessary in order that the net amounts received by the Bank after such deduction or withholding shall equal the amounts which would have been received if such deduction or withholding were not required, provided that the Borrower shall be required to pay such additional amounts only if (A) such withholding Tax is imposed as a result of a change in law after the Closing Date (or, in the case of a transferee of the Bank, if such withholding Tax is imposed as a result of a change in law after the date the transferee became a party hereto) and (B) such withholding Tax is not imposed as a result of the failure of the Bank (or any transferee of the Bank) to provide such properly completed and duly executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding, but only to the extent the Bank (or such transferee) is legally permitted to provide such documentation.

3.6 Reduction or Termination of the Commitment. The Borrower may at any time or from time to time reduce or terminate the Commitment by giving written notice thereof no later than 2:00 p.m. (Central time) not less than two (2) Business Days’ prior to such reduction or termination. Any reduction in the Commitment shall be effective on the date specified in the Borrower’s notice with respect to such reduction. The Commitment shall automatically terminate on the earlier of (i) the Maturity Date or (ii) in the event of acceleration of the Maturity Date of the Note. Each reduction of the Commitment hereunder shall be irrevocable.

ARTICLE IV.

As of the Closing Date, there are no outstanding warrants, options, contracts or commitments of any kind entitling any Person to purchase or otherwise acquire (i) any shares of the Capital Stock of the Borrower or (ii) any securities convertible into or exchangeable for any shares of such Capital Stock.

The Liens created by the International Security Documents will constitute valid and perfected Liens on the Collateral described therein superior in right to all other Liens, except for Permitted Liens.

6.8 Taxes. The Borrower and each Subsidiary has timely filed, or has caused to be timely filed, all tax returns and reports required by applicable law, has timely paid, or has caused to be timely paid, all applicable taxes, assessments, deposits and contributions owing by Borrower and each such Subsidiary and will timely pay, or cause to be timely paid, all such items in the future as they became due and payable.

The Bank may also proceed either by the specific performance of any covenant or agreement contained in this Agreement or the other International Loan Documents or by enforcing the payment of the Obligations provided under this Agreement or the other International Loan Documents or otherwise existing under any law. The Bank shall not, however, be under any obligation to marshal any assets in favor of the Borrower or against or in payment of any or all obligations under any International Loan Document.

Upon the payment or expiry of all Letter of Credit Outstandings, all such Collateral shall be promptly released to the Borrower in due course at Borrower’s cost.

10.4 Exit Date Event of Default. On the date that is thirty (30) days after the date that Wells Fargo notifies the Borrower that it is assigning its interests in the Domestic Credit Agreement to a Person other than Wells Fargo, an Affiliate of Wells Fargo or an Affiliate of the Bank and an Exit Date has occurred during such thirty day period, then an Exit Date Event of Default shall be deemed to have occurred and the Commitment of the Bank and the obligation of the Bank to issue or cause to be issued Letters of Credit hereunder shall (unless Ex-Im Bank shall have consented to the issuance of additional Letters of Credit) automatically be terminated, whereupon the same shall forthwith terminate and no additional Letters of Credit shall be issued without Ex-Im Bank’s written consent. Notwithstanding anything to the contrary, if the only Event of Default that has occurred and is continuing is an Exit Date Event of Default, then the Bank and the Secured Party (as defined in the International Security Agreement) shall not have the right to exercise any right or remedy (other than those rights and remedies set forth in this Section 10.4) that may only be exercised upon the occurrence and during the continuance of an Event of Default.

10.5 Remedies Cumulative. No remedy, right or power conferred upon the Bank is intended to be exclusive of any other remedy, right or power given hereunder or now or hereafter

existing at law, in equity, or otherwise, and all such remedies, rights and powers shall be cumulative.

ARTICLE XI.
MISCELLANEOUS.

11.1 Waivers, Amendments. No failure or delay on the part of the Bank in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No course of dealing between the Borrower or any Subsidiary of such Borrower, any Guarantor and the Bank shall operate as a waiver of any right of the Bank or Ex-Im Bank. No amendment, modification or waiver of any provision of this Agreement, the Note or any other International Loan Document nor consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be (i) approved by Ex-Im Bank and (ii) in writing signed by all the parties thereto, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Except as otherwise provided by any International Loan Document or applicable law, no notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

11.2 Reimbursement of Expenses. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT SHALL BE CONSUMMATED, THE BORROWER AGREES TO REIMBURSE THE BANK FOR ITS REASONABLE OUT-OF-POCKET EXPENSES, INCLUDING THE REASONABLE FEES AND EXPENSES OF OUTSIDE COUNSEL TO THE BANK, IN CONNECTION WITH SUCH TRANSACTIONS, OR ANY OF THEM, OR OTHERWISE IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER INTERNATIONAL LOAN DOCUMENT, INCLUDING (A) THE NEGOTIATION, PREPARATION, EXECUTION, ADMINISTRATION, MODIFICATION AND ENFORCEMENT OF THIS AGREEMENT OR ANY OTHER INTERNATIONAL LOAN DOCUMENT, AND (B) REASONABLE OUT-OF-POCKET COSTS AND EXPENSES OF THE BANK IN CONNECTION WITH DUE DILIGENCE, TRANSPORTATION AND DUPLICATION.

11.5 Survival of Representations, Warranties and Covenants. All representations, warranties and covenants contained herein or made in writing by the Borrower and the Guarantors in connection herewith shall survive the execution and delivery of this Agreement and the Note, and will bind and inure to the benefit of the respective successors and assigns of the parties hereto, whether so expressed or not. No investigation at any time made by or on behalf of the Bank shall diminish the Bank’s right to rely thereon.

11.6 Counterparts. This Agreement may be executed in several counterparts, and by the parties hereto on separate counterparts, and each counterpart, when so executed and delivered, shall constitute an original instrument, and all such separate counterparts shall constitute but one and the same instrument.

11.7 Separability. Should any clause, sentence, paragraph or Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this Agreement so held to be invalid, unenforceable or void will be

deemed to have been stricken herefrom and the remainder will have the same force and effectiveness as if such part or parts had never been included herein.

11.8 Limitation of Liability. No claim may be made by the Borrower or the Affiliates, directors, officers, employees, attorneys, or agents of the Borrower against the Bank or the Affiliates, directors, officers, employees, attorneys, or agents of the Bank for any special, indirect, consequential or punitive damages in respect of any claim for breach of contract arising out of or related to the transactions contemplated by this Agreement, or any act, omission, or event occurring in connection herewith; and the Borrower hereby waives, releases, and agrees not to sue upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

11.9 Set-off. If an Event of Default has occurred and is continuing, the Borrower hereby gives and confirms to the Bank a right of set-off of all moneys, securities and other property of the Borrower (whether special, general or limited) and the proceeds thereof, now or hereafter delivered to remain with or in transit in any manner to the Bank, its correspondents or its agents from or for the Borrower, whether for safekeeping, custody, pledge, transmission, collection or otherwise or coming into possession of the Bank in any way, and also, any balance of any deposit accounts and credits of the Borrower with, and any and all claims of security for the payment of the Obligations, and the Borrower hereby authorize the Bank at any time or times, without prior notice, to apply such money, securities, other property, proceeds, balances, credits of claims, or any part of the foregoing, to such Obligations in such amounts as it may select, whether such liabilities be contingent, unmatured or otherwise, and whether any collateral security therefor is deemed adequate or not. The rights described herein shall be in addition to any collateral security described in any separate agreement executed by the Borrower.

11.10 Sale or Assignment. The Bank may assign its rights hereunder and under each other International Loan Document and the Liens granted pursuant to the International Security Documents only to Ex-Im Bank in accordance with the terms and conditions of the Ex-Im Bank Guaranty. Notwithstanding the foregoing, the Bank may assign, transfer, negotiate, sell or participate all or part of its interests and rights in the Letters of Credit to an Affiliate or Subsidiary of the Bank, provided that the Bank retains all obligations under the Ex-Im Bank Guaranty with respect to Ex-Im Bank and the International Loan Documents.

11.11 Interest. All agreements between the Borrower, any Guarantor and the Bank, whether now existing or hereafter arising and whether written or oral, are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of demand being made on the Note or otherwise, shall the amount paid, or agreed to be paid, to the Bank for the use, forbearance, or detention of the money to be loaned under this Agreement or otherwise or for the payment or performance of any covenant or obligation contained herein or in any other International Loan Document exceed the Highest Lawful Rate. If, as a result of any circumstances whatsoever, fulfillment of any provision hereof or of any of such documents, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by applicable usury law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if, from any such circumstance, the Bank shall ever receive interest or anything which might be deemed interest under applicable law which would exceed the Highest Lawful Rate, such amount which would be excessive interest shall be applied

to the reduction of the principal amount owing on account of the Obligations or the amounts owing on other obligations of the Borrower or any Guarantor to the Bank under any International Loan Document and not to the payment of interest, or if such excessive interest exceeds the unpaid principal balance of the Obligations and the amounts owing on other obligations of the Borrower and any Guarantor to the Bank under any International Loan Document, as the case may be, such excess shall be refunded to the Borrower or such Guarantor, as applicable. All sums paid or agreed to be paid to the Bank for the use, forbearance, or detention of the indebtedness of the Borrower and the Guarantors to the Bank shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term of such indebtedness until payment in full of the principal thereof (including the period of any renewal or extension thereof) so that the interest on account of such indebtedness shall not exceed the Highest Lawful Rate. Notwithstanding anything to the contrary contained in this Agreement or the Note, it is understood and agreed that if at any time the rate of interest which accrues on the outstanding Obligations shall exceed the Highest Lawful Rate, the rate of interest which accrues on the outstanding Obligations shall be limited to the Highest Lawful Rate, but any subsequent reductions in the rate of interest which accrues on the outstanding Obligations shall not reduce the rate of interest which accrues on the outstanding Obligations below the Highest Lawful Rate until the total amount of interest accrued on the outstanding Obligations equals the amount of interest which would have accrued if such interest rate had at all times been in effect.

To the extent that the Borrower makes a payment or payments to the Bank or the Bank enforces any security interest or exercises its right of setoff, and such payment or payments or the proceeds of such enforcement or setoff 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 Person under any Debtor Law or equitable cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and shall continue in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

11.14 Credit Agreement Controls. If there are any conflicts or inconsistencies between this Agreement and any of the other International Loan Documents, the provisions of this Agreement shall prevail and control.
