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.

-2-

(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.

-3-

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.

-4-

(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

-5-

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.

-6-

(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.

-7-

(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

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.

Fees shall be payable when due in Dollars and in immediately available funds.

ARTICLE V.

PERMITTED PURPOSES OF LETTERS OF CREDIT

The Borrower agrees that the Letters of Credit shall be issued solely to support one or more of the Borrower’s, any Guarantor’s or any Eligible Joint Venture’s obligations under an Export Order.

10.2 Other Remedies. In addition to and cumulative of any rights or remedies expressly provided for in this Article X, if any one or more Events of Default shall have occurred (other than an Exit Date Event of Default), the Bank may proceed to protect and enforce its rights hereunder by any appropriate proceedings and the Liens evidenced by the International Security Documents shall be subject to foreclosure in any manner provided for therein or provided for by law as the Bank may elect. 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 occurrence of an Event of Default (other than an Exit Date Event of Default), it is hereby acknowledged and agreed Ex-Im Bank shall have the right to (a) direct the Bank to make demand hereunder and under the other International Loan Documents and (b) request that the Bank declare all outstanding Obligations, to be forthwith due and payable, and the Bank shall have no liability to the Borrower for complying with such directions or requirements.

The Borrower hereby agrees to execute and deliver to the Bank such security agreements, pledges or other documents as the Bank may, from time to time, require to perfect the pledge, lien and security interest in and to any such funds provided for in this Section 10.3. 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

-31-

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.

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.

11.9 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.

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

-34-

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.

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.

11.15 Amendment of Financial Covenants. Notwithstanding anything herein to the contrary, the parties hereto agree that any amendment to or waiver to the financial covenants set forth in Section 6.3 (or any comparable section) of the Domestic Credit Agreement or any related term or definition used therein shall, subject to the prior written approval of Ex-Im Bank and Bank, automatically amend or waive the corresponding financial covenants set forth in Section 9.5 of this Agreement and any related term or definition used therein in the same manner. Subject to the prior written approval of Ex-Im Bank, the Bank agrees to execute an amendment or waiver to this Agreement to document such automatic amendment or waiver of the financial covenants and related terms and conditions.

INTERNATIONAL REVOLVING NOTE


$20,000,000.00		September 29, 2006

FOR VALUE RECEIVED, the undersigned, GREAT LAKES DREDGE & DOCK CORPORATION, a Delaware corporation (the “Borrower”), HEREBY PROMISES TO PAY to the order of WELLS FARGO HSBC TRADE BANK, N.A. (the “Bank”), on or before December 31, 2008 (the “Maturity Date”), the principal sum of Twenty Million and 00/100 Dollars ($20,000,000.00), or, if less, the aggregate principal amount of the Obligations outstanding on the Maturity Date, in accordance with the terms and provisions of that certain Letter of Credit Agreement dated as of September 29, 2006 by and between the Borrower and the Bank (as amended from time to time, the “Agreement”; capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed to such terms in the Agreement).

The outstanding principal balance of this Note shall be due and payable as provided in the Agreement. The Borrower promises to pay interest on the outstanding principal amount of Obligations from and including the date of any Unpaid Drawing evidenced by this Note to but not including the Maturity Date at the rate or rates, and shall be due and payable on the dates, set forth in the Agreement. Interest shall accrue and be payable at the Default Rate when provided for in the Agreement.

Payments of principal and interest, and all amounts due with respect to costs and expenses, shall be made in lawful money of the United States of America in immediately available funds, without deduction, set-off or counterclaim to the Bank in accordance with Section 3.3 of the Agreement, on the dates on which such payments shall become due pursuant to the terms and provisions set forth in the Agreement.

If any payment of principal or interest on this Note shall become due on a Saturday, Sunday, or public holiday on which the Bank is not open for business, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in computing interest in connection with such payment.

All payments and prepayments made hereon shall be recorded in the holder’s records and such records shall be controlling, absent manifest error.

In addition to all principal and accrued interest on this Note, the Borrower agrees to pay (a) all reasonable out-of-pocket costs and expenses incurred by any owners and holders of this Note in collecting this Note through any probate, reorganization, bankruptcy or any other proceeding and (b) reasonable attorneys’ fees when and if this Note is placed in the hands of an attorney for collection after default.

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 this 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 the Agreement and evidenced by this Note or otherwise or for the payment or performance of any covenant or obligation contained in the Agreement, this Note 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 and 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 the Bank under any International Loan Documents, 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 the Agreement or this 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. The terms and provisions of this paragraph shall control and supersede every other provision of all agreements between the Borrower, the Guarantors and the Bank.

This Note is entitled to the benefits of the Agreement, which Agreement, among other things, contains provisions for acceleration of the maturity hereof upon the happening of certain stated events, for prepayments on account of principal hereof prior to the maturity hereof upon the terms and conditions and with the effect therein specified, and provisions to the effect that no provision of the Agreement or this Note shall require the payment or permit the collection of interest in excess of the Highest Lawful Rate. The obligations of the Borrower hereunder are secured by the International Security Documents. It is contemplated that by reason of prepayments or repayments hereon prior to the Maturity Date, there may be times when no indebtedness is owing hereunder prior to such date, but notwithstanding such occurrences, this Note shall remain valid and shall be in full force and effect as to reimbursement obligations in respect of Letters of Credit issued pursuant to the Agreement subsequent to each such issuance.

Except as otherwise specifically provided for in the Agreement, the Borrower and any and all endorsers, guarantors and sureties severally waive grace, demand, presentment for

payment, notice of dishonor or default, protest, notice of protest, notice of intent to accelerate, notice of acceleration and diligence in collecting and bringing of suit against any party hereto, and agree to all renewals, extensions or partial payments hereon, with or without notice, before or after maturity.

THIS NOTE, THE OTHER INTERNATIONAL LOAN DOCUMENTS (UNLESS ANY SUCH INTERNATIONAL LOAN DOCUMENT EXPRESSLY PROVIDES OTHERWISE) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS CONFLICTS OF LAW PRINCIPLES (OTHER THAN PROVISIONS OF 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

THIS NOTE AND THE OTHER INTERNATIONAL LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AS TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES; AND THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

IN WITNESS WHEREOF, the Borrower has caused this Note to be executed and delivered by its officer thereunto duly authorized effective as of the date first above written.

GUARANTY

This Guaranty (herein referred to as the “Guaranty”) is dated as of September 29, 2006, and is executed by GREAT LAKES DREDGE & DOCK COMPANY, LLC, a Delaware limited liability company (the “Guarantor”), in order to induce WELLS FARGO HSBC TRADE BANK, N.A., a national banking association (“Trade Bank”), and WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking association (“Wells Fargo”) (Trade Bank and Wells Fargo are singly, a “Bank”, and collectively, the “Banks”), to provide financial accommodations to GREAT LAKES DREDGE & DOCK CORPORATION, a Delaware corporation (the “Borrower”).

1. GUARANTY; DEFINITIONS. In consideration of any credit or other financial accommodation heretofore, now or hereafter extended or made to the Borrower by the Banks and for other valuable consideration, the undersigned Guarantor and any debtor-in-possession or trustee in bankruptcy, heir, executor or other successor which succeeds to the interest of the Guarantor hereby unconditionally guarantees the full and prompt payment to the Banks, or order, on demand in lawful money of the United States of America and in immediately available funds, of any and all Obligations of the Borrower to the Banks, provided, however the Guarantor acknowledges and agrees (a) the Obligations guaranteed hereunder shall include obligations and liabilities arising out of the Standby Letter of Credit Agreement and all instruments, certificates and agreements executed in connection therewith owed by any Loan Party to Wells Fargo or any affiliate thereof pursuant to the terms thereto and (b) all references herein to “Obligations” herein shall include such Obligations described in clause (a) hereof for all purposes hereunder. As used in this Guaranty, the term “Obligations” means all Obligations as defined in that certain International Letter of Credit Agreement dated as of September 29, 2006, by and among the Borrower, the other Loan Parties, including the Guarantor, from time to time party thereto and Trade Bank (as amended, restated, supplemented or otherwise modified from time to time, the “Letter of Credit Agreement”); terms used herein and not otherwise defined herein shall have the meanings set forth in the Letter of Credit Agreement). Notwithstanding anything in this Guaranty to the contrary, the obligations of the Guarantor under this Guaranty shall be limited to a maximum aggregate amount equal to the largest amount that would not render the Guarantor’s obligations hereunder subject to avoidance as a fraudulent transfer or fraudulent conveyance under Section 548 of Title 11 of the United States Code or any applicable provisions of comparable state law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of the Guarantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws and after giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement or contribution of the Guarantor pursuant to (y) applicable law, or (z) any agreement providing for rights of subrogation, reimbursement or contribution in favor of the Guarantor, or for an equitable allocation among the Guarantor, the Borrower, and any other person or entity liable for the Obligations.

2. SUCCESSIVE TRANSACTIONS; REVOCATIONS; OBLIGATION UNDER OTHER GUARANTIES. This Guaranty shall be an absolute, continuing, irrevocable, and unconditional guaranty of payment and performance and not a guaranty of collection, and

GUARANTY – Page 1

the Guarantor shall remain liable on its obligations hereunder until the indefeasible payment and performance in full of the Obligations and the termination of all commitments by the Trade Bank to extend credit to or for the benefit of the Borrower under the Letter of Credit Agreement. All rights, powers and remedies under this Guaranty shall apply to all past, present and future Obligations of the Borrower to the Banks, including those arising under successive transactions which shall either continue the Obligations, increase or decrease the Obligations, or from time to time create new Obligations after all or any prior part of the Obligations has been satisfied, and notwithstanding the dissolution, liquidation or bankruptcy of the Borrower or the Guarantor or any other event or proceeding affecting the Borrower or the Guarantor. No set-off, counterclaim, recoupment, reduction, or diminution of any obligation, or any defense of any kind or nature (other than payment or performance) which the Borrower may have against either Bank, or any other party, or which the Guarantor may have against the Borrower, either Bank, or any other party, shall be available to, or shall be asserted by, the Guarantor against either Bank, or any subsequent holder of the Obligations or any part thereof or against payment of the Obligations or any part thereof. If the Guarantor becomes liable for any indebtedness owing by the Borrower to the Banks by endorsement or otherwise, other than under this Guaranty, such liability shall not be in any manner impaired or affected hereby, and the rights of the Banks hereunder shall be cumulative of any and all other rights that the Banks may ever have against the Guarantor. The exercise by either Bank of any right or remedy hereunder or under any other instrument, or at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy.

3. SEPARATE ACTIONS; WAIVER OF STATUTE OF LIMITATIONS; REINSTATEMENT OF LIABILITY. The obligations hereunder are independent of the obligations of the Borrower, and a separate action or actions may be brought and prosecuted against the Guarantor whether action is brought against the Borrower or any other person, or whether the Borrower or any other person is joined in any such action or actions. A separate action or actions may be bought and prosecuted against the Guarantor by the either Bank; the Banks do not need to join each other in any such action. The Guarantor acknowledges that there are no conditions precedent to the effectiveness of this Guaranty, and this Guaranty is in full force and effect and is binding on the Guarantor as of the date first written above, regardless of whether either Bank obtains collateral or any guaranties from others or takes any other action contemplated by the Guarantor. The Guarantor waives, to the extent permitted under applicable law, the benefit of any statute of limitations affecting the Guarantor’s liability hereunder or the enforcement thereof, and the Guarantor agrees that any payment of any Obligations or other act which shall toll any statute of limitations applicable thereto shall similarly operate to toll such statute of limitations applicable to the Guarantor’s liability hereunder. The liability of the Guarantor hereunder shall be reinstated and revived and the rights of the Banks shall continue if and to the extent for any reason any amount at any time paid on account of any Obligations guaranteed hereby is rescinded or must otherwise be restored by either Bank, whether as a result of any proceeding in bankruptcy or reorganization or otherwise, all as though such amount had not been paid. The determination as to whether any amount so paid must be rescinded or restored shall be made by each Bank in its sole discretion; provided, however, that if a Bank chooses to contest any such matter at the request of the Guarantor, the Guarantor agrees to indemnify and hold the Banks harmless from and against all costs and expenses, including reasonable attorneys’ fees expended or incurred by the Banks in connection therewith, including, without limitation, in any litigation with respect thereto.

Each Bank may without notice assign this Guaranty in whole or in part.

5. COVENANTS.

6. REPRESENTATIONS AND WARRANTIES. The Guarantor represents and warrants to the Banks that: (a) this Guaranty is executed at the Borrower’s request; (b) neither Bank has made any representation to the Guarantor as to the creditworthiness of the Borrower or any other person or entity liable for the Obligations; (c) the Guarantor has established adequate means of obtaining from the Borrower on a continuing basis financial and other information pertaining to the Borrower’s financial condition; (d) the Guarantor has the power and authority to execute, deliver and perform its obligations under this Guaranty, and this Guaranty constitutes the legal, valid and binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its terms, except as limited by Debtor Laws; (e) the execution, delivery, and performance by the Guarantor of this Guaranty will not violate any law or any order of any court, governmental authority or arbitrator and will not conflict with, result in a breach of, or constitute a default under, or result in the imposition of any lien (other than Liens created or permitted under the International Loan Documents) upon any assets of the Guarantor pursuant to the provisions of any indenture, mortgage, deed of trust, security agreement, franchise, permit, license, or other instrument or agreement to which the Guarantor or its properties is bound; (f) the Guarantor has read and understands the terms and conditions of the International Loan Documents; (g) the value of the consideration received and to be received by the Guarantor as a result of the Banks making extensions of credit to the Borrower and the Guarantor executing and delivering this Guaranty is reasonably worth at least as much as the liability and obligation of the Guarantor hereunder, and such liability and obligation and such extensions of credit may reasonably be expected to benefit the Guarantor directly or indirectly; (h) the fair value of the

GUARANTY – Page 3

assets of the Guarantor (on a going concern basis) is, after giving effect to this Guaranty, greater than the total amount of liabilities (including contingent and unliquidated liabilities) of the Guarantor after giving effect to this Guaranty, and that, after giving effect to this Guaranty, the Guarantor is able to pay all of its liabilities as they mature in the ordinary course and it does not have unreasonably small capital with which to carry on its business. The Guarantor agrees to keep adequately informed from such means of any facts, events or circumstances which might in any way affect the Guarantor’s risks hereunder, and the Guarantor further agrees that the Banks shall not have any obligation to disclose to the Guarantor any information or material about the Borrower or any other person or entity liable for the Obligations which is acquired by the Banks in any manner.

7.2. The Guarantor irrevocably and unconditionally waives, to the extent permitted under applicable law, all suretyship defenses and any defense to its obligations hereunder based upon or arising by reason of: (a) any disability or other defense of the Borrower or any other person; (b) the cessation or limitation from any cause whatsoever, other than indefeasible payment in full, of the Obligations of the Borrower or any other person; (c) any lack of authority of any officer, director, partner, agent or any other person acting or purporting to act on behalf of the Borrower which is a corporation, partnership or other type of entity, or any defect in the formation of the Borrower; (d) the application by the Borrower of the proceeds of any Obligations for purposes other than the purposes represented by the Borrower to, or intended or understood by, the Banks or the Guarantor; (e) any act or omission by the Banks which directly or indirectly results in or aids the discharge of the Borrower or any other person or entity liable for the Obligations or any portion of the Obligations by operation of law or otherwise, or which in any way impairs or suspends any rights or remedies of the Banks against the Borrower or any other person or entity liable for the Obligations; (f) any impairment of the value of any interest in any security for the Obligations or any portion thereof, including, without limitation, the failure to obtain or maintain perfection or recordation of any interest in any such security, the release of any such security without substitution, and/or the failure to preserve the value of, or to comply with applicable law in disposing of, any such security; (g) any modification of the Obligations, in any form whatsoever, including any modification made after revocation hereof to any Obligations incurred prior to such

The Guarantor hereby waives notice of intent to accelerate the Obligations and notice of acceleration of the Obligations.

The Guarantor further waives all rights and defenses the Guarantor may have arising out of (A) any election of remedies by either Bank, even though that election of remedies, such as a non-judicial foreclosure with respect to any security for any portion of the Obligations, destroys the Guarantor’s rights of subrogation or the Guarantor’s rights to proceed against the Borrower or any other person or entity for reimbursement, or (B) any loss of rights the Guarantor may suffer by reason of any rights, power or remedies of the Borrower in connection with any anti-deficiency laws or any other laws limiting, qualifying or discharging the Borrower or any of the Obligations. Until all Obligations shall have been indefeasibly paid in full and the termination of all commitments by the Trade Bank to extend credit to or for the benefit of the Borrower under the Letter of Credit Agreement, the Guarantor further waives any right to enforce any remedy which either Bank now has or may hereafter have against the Borrower or any other person, and waives any benefit of, or any right to participate in, any security now or hereafter held by either Bank.

Any waiver, permit, consent or approval of any kind by either Bank either any breach of this Guaranty, or any such waiver of any provision or condition thereof, must be in writing, must be signed by the Banks and shall be in effect only to the extent set forth in writing.

10. COSTS, EXPENSES AND ATTORNEYS’ FEES.

Upon the execution and delivery by any Person of a Joinder to Guaranty in the form of Exhibit G to the Letter of Credit Agreement, such Person (i) shall be and become a Guarantor hereunder and (ii) a party to the Letter of Credit Agreement and each reference in this Guaranty and the other International Loan Documents to “Guarantor” shall also mean a reference to such Person. The execution and delivery of such Joinder to Guaranty shall not require the consent of any other Guarantor hereunder, and the rights and obligations of each Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor as a party to this Guaranty.

12. SUCCESSORS, ASSIGNS. This Guaranty shall be binding upon and inure to the benefit of the successors and assigns of the parties (including any debtor-in-possession or trustee in bankruptcy); provided, that the Guarantor may not assign or transfer any of its interest, rights or obligations hereunder without the Banks’ prior written consent. The Guarantor acknowledges that each Bank has the right to sell, assign, transfer, negotiate or grant participation in all or in any part of, or any interest in, any Obligations of the Borrower to such Bank and any obligations with respect thereto, including this Guaranty.

GUARANTY – Page 6

herein provided. This Guaranty is intended by the Guarantor to be the final, complete and exclusive expression of the agreement between the Guarantor and the Banks. This Guaranty may be amended or modified only in writing signed by the Banks and the Guarantor.

14. UNDERSTANDING WITH RESPECT TO WAIVERS; SEVERABILITY OF PROVISIONS. The Guarantor warrants and agrees that each of the waivers set forth herein is made by the Guarantor’s full knowledge of its significance and consequences, and that under the circumstances, the waivers are reasonable and not contrary to public policy or law. If any waiver or other provision of this Guaranty shall be held to be prohibited by or invalid under applicable public policy or law, such waiver or other provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such waiver or other provision or any remaining provisions of this Guaranty.

15. COUNTERPARTS. This Guaranty may be executed in any number of counterparts, each of which shall constitute an original, but all of which when taken together shall constitute one and the same Guaranty. A telecopy or electronic copy of any such executed counterpart shall be deemed valid as an original.

16. GOVERNING LAW. This Guaranty shall be governed by and construed in accordance with the laws of the State of New York without regard to its conflicts of law principles (other than the provisions of 5-1401 and 5-1402 of the New York General Obligations Law).

18. COMPLIANCE WITH APPLICABLE USURY LAWS. It is the intention of the Banks and the Guarantor to contract in strict compliance with applicable usury law from time to time in effect. In furtherance therefore, such persons stipulate and agree that none of the terms and provisions contained in this Guaranty or any other International Loan Document shall ever be construed to create a contract to pay for the use, forbearance or detention of money interest in excess of the maximum interest permitted to be charged by applicable law from time to time in effect. Neither the Guarantor nor any of its subsidiaries or affiliates nor any present or future guarantors, endorsers, or other parties hereafter becoming liable for payment of the Obligations shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of maximum interest that may be lawfully charged under applicable law from time to time in effect, and that provisions of this Section shall control over all other provision of this Guaranty or any other International Loan Document which may be in apparent conflict herewith. In the event that the Banks or any other holder of the Obligations shall collect moneys which are deemed to constitute interest which would otherwise increase the effective interest on the Obligations or any part thereof to an amount in excess of that permitted to be charged by applicable law then in effect, all such sums deemed to constitute interest in excess of such legal limit shall be immediately returned to the Guarantor or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific

GUARANTY – Page 7

contingency, exceeds the maximum amount permitted under applicable law, the Banks and the Guarantor (and any other payors thereof) shall to the greatest extent permitted under applicable law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread the total amount of interest throughout the maximum available period of time in accordance with the amounts owing by the Guarantor from time to time and the maximum legal rates of interest from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable law. The term “applicable law” as used herein shall mean the law of the State of New York or the laws of the United States, whichever laws allow the greater rate of interest, as such laws now exist or may be changed or amended or come into effect in the future.

19. FINAL AGREEMENT. THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

20. NOTICES. ALL NOTICES, REQUESTS AND OTHER COMMUNICATIONS TO THE GUARANTOR OR THE TRADE BANK HEREUNDER SHALL BE GIVEN IN WRITING (INCLUDING BANK WIRE, TELEX OR SIMILAR WRITING AND SHALL BE EFFECTIVE IN ACCORDANCE WITH THE PROVISIONS OF THE LETTER OF CREDIT AGREEMENT, AND SHALL BE GIVEN FOR (A) THE GUARANTOR AT THE “ADDRESSES FOR NOTICES” SPECIFIED ON THE SIGNATURE PAGE HEREOF AND (B) THE TRADE BANK AT THE ADDRESS PROVIDED IN THE LETTER OF CREDIT AGREEMENT.

RESTRICTED ACCOUNT AGREEMENT

(Access Restricted Immediately)

This Restricted Account Agreement (the “Agreement”), dated as of the date specified on the initial signature page of this Agreement, is entered into by and among Great Lakes Dredge & Dock Company, LLC (“Company”), Wells Fargo HSBC Trade Bank N.A. (“Secured Party”) and Wells Fargo Bank, National Association (“Bank”), and sets forth the rights of Secured Party and the obligations of Bank with respect to the deposit account(s) of Company at Bank identified at the end of this Agreement as the “Restricted Account(s)”. As used in this Agreement, the term “Restricted Account” refers, individually and collectively, to each such deposit account.

Secured Party’s Interest in Restricted Account. Secured Party represents that it is either (i) a lender who has extended credit to Company and has been granted a security interest in the Restricted Account or (ii) such a lender and the agent for a group of such lenders (the “Lenders”). Company hereby confirms, and Bank hereby acknowledges, the security interest granted by Company to Secured Party in all of Company’s right, title and interest in and to the Restricted Account and all sums now or hereafter on deposit in or payable or withdrawable from the Restricted Account (the “Account Funds”). Except as specifically provided otherwise in this Agreement, Company has given Secured Party complete control over the Account Funds. Secured Party hereby appoints Bank as agent for Secured Party only for the purpose of perfecting the security interest of Secured Party in the Account Funds while they are in the Restricted Account. Company and Secured Party would like to use the Restricted Account Service of Bank described in this Agreement (the “Service”) to further the arrangements between Secured Party and Company regarding the Restricted Account and the Account Funds.

Access to Restricted Account. Company agrees that it will not be able to make debits or withdrawals from the Restricted Account, that it will not have access to the Restricted Account or any Account Funds, and that Secured Party will have exclusive access to the Restricted Account and Account Funds, except as specifically provided in this Agreement or as specifically agreed by Secured Party in writing.

Balance Reports. Bank agrees, at the telephone request of Secured Party on any Business Day (a day on which Bank is open to conduct its regular banking business, other than a Saturday, Sunday or public holiday), to make available to Secured Party a report (“Balance Report”) showing the opening available balance in the Restricted Account as of the beginning of such Business Day, either on-line or by facsimile transmission, at Bank’s option. Company expressly consents to this transmission of information. Secured Party and Company understand and agree that the opening available balance in the Restricted Account at the beginning of any Business Day will be determined after deducting from the Restricted Account the face amount of all Returned Items (as defined in Section 5 of this Agreement).

4.	Transfers From Restricted Account. Unless otherwise instructed by Secured Party, Bank agrees that on each Business Day it will transfer to Company’s account specified at the end of this Agreement with the bank specified at the end of this Agreement (the “Company Remote


RestAcctAgmt-Std-NS		Page 1
(Revised 08/09/05)

Account”) the full amount of each payment received provided the funds comprising each payment are collected funds, such transfer to be made on the same Business Day as received if received on or before 2:00 p.m. (Central time) and for each payment received after 2:00 p.m. (Central time), shall be transferred the next Business Day. Bank will use the Fedwire system to make each funds transfer unless for any reason the Fedwire system is unavailable, in which case Bank will determine the funds transfer system to be used in making each funds transfer and the means by which each transfer will be made. Bank, Secured Party and Company each agree that Bank will comply with instructions given to Bank by Secured Party directing disposition of funds in the Restricted Account without further consent by Company, subject otherwise to the terms of this Agreement and Bank’s standard policies, procedures and documentation in effect from time to time governing the type of disposition requested. Except as otherwise required by law, Bank will not agree with any third party to comply with instructions for disposition of funds in the Restricted Account originated by such third party. So long as no Event of Default has occurred and is continuing under the Letter of Credit Agreement (defined below), Secured Party will deliver orders to Bank providing for a daily transfer of funds from the Restricted Account to the Company Remote Account in accordance with the terms hereof. As used herein, “Letter of Credit Agreement” means that certain International Letter of Credit Agreement dated as of September 29, 2006, by and among the Company, Great Lakes Dredge and Dock Corporation and Secured Party.

Returned Item Amounts. Secured Party and Company understand and agree that the face amount (“Returned Item Amount”) of each Returned Item will be paid by Bank debiting the Restricted Account, without prior notice to Secured Party or Company. As used in this Agreement, the term “Returned Item” means (i) any item deposited to the Restricted Account and returned unpaid, whether for insufficient funds or for any other reason, and without regard to the timeliness of such return or the occurrence or timeliness of any drawee’s notice of non-payment; (ii) any item subject to a claim against Bank of breach of transfer or presentment warranty under the Uniform Commercial Code, as adopted in the applicable state; (iii) any automated clearing house (“ACH”) entry credited to the Restricted Account and returned unpaid or subject to an adjustment entry under applicable clearing house rules, whether for insufficient funds or for any other reason, and without regard to the timeliness of such return or adjustment; (iv) any credit to the Restricted Account from a merchant card transaction, against which a contractual demand for chargeback has been made; and (v) any credit to the Restricted Account made in error. Company agrees to pay all Returned Item Amounts immediately on demand, without setoff or counterclaim, to the extent there are not sufficient funds in the Restricted Account to cover the Returned Item Amounts on the day they are to be debited from the Restricted Account. Secured Party agrees to pay all Returned Item Amounts within thirty (30) calendar days after demand, without setoff or counterclaim, to the extent that (i) the Returned Item Amounts are not paid in full by Company within fifteen (15) calendar days after demand on Company by Bank, and (ii) Secured Party has received proceeds from the corresponding Returned Items.

6.	[Reserved.]

Bank Fees. Company agrees to pay all reasonable customary Bank’s fees and charges for the maintenance and administration of the Restricted Account and for the treasury management and other account services provided with respect to the Restricted Account (collectively “Bank Fees”), including, but not limited to, the fees for (a) the Balance Reports provided on the Restricted Account, (b) the wire transfer services received with respect to the Restricted Account, (c) Returned Items, (d) funds advanced to cover overdrafts in the Restricted Account (but without Bank being in any way obligated to make any such advances), and (e) duplicate bank statements on the Restricted Account. The Bank Fees will be paid by Bank debiting the

(Revised 08/09/05)

Restricted Account on the Business Day that the Bank Fees are due without notice to Secured Party or Company. If there are not sufficient funds in the Restricted Account to cover fully the Bank Fees on the Business Day they are to be debited from the Restricted Account, such shortfall or the amount of such Bank Fees will be paid by Company sending Bank a check in the amount of such shortfall or such Bank Fees, without setoff or counterclaim, within thirty (30) calendar days after written demand to Company by Bank. Secured Party agrees to pay the Bank Fees within forty-five (45) calendar days after demand, without setoff or counterclaim, to the extent such Bank Fees are not paid in full by Company within thirty (30) calendar days after demand on Company by Bank.

Account Documentation. Secured Party and Company agree that, except as specifically provided in this Agreement, the Restricted Account will be subject to, and Bank’s operation of the Restricted Account will be in accordance with, the terms and provisions of Bank’s Commercial Account Agreement or other deposit account agreement governing the Restricted Account (“Account Agreement”).

Company and/or Secured Party will have thirty (30) calendar days after receipt of a bank statement to notify Bank of an error in such statement. Bank’s liability for such errors is limited as provided in the “Limitation of Liability” section of this Agreement.

10.

Partial Subordination of Bank’s Rights. Bank hereby subordinates to the security interest of Secured Party in the Restricted Account (i) any security interest which Bank may have or acquire in the Restricted Account, and (ii) any right which Bank may have or acquire to set off or otherwise apply any Account Funds against the payment of any indebtedness from time to time owing to Bank from Company, except for debits to the Restricted Account permitted under this Agreement for the payment of Returned Item Amounts or Bank Fees.

11.

Bankruptcy Notice; Effect of Filing. If Bank at any time receives notice of the commencement of a bankruptcy case or other insolvency or liquidation proceeding by or against Company (a “Bankruptcy Notice”), Bank will continue to comply with its obligations under this Agreement, except to the extent that any action required of Bank under this Agreement is prohibited under applicable bankruptcy laws or regulations or is stayed pursuant to the automatic stay imposed under the United States Bankruptcy Code or by order of any court or agency. With respect to any obligation of Secured Party hereunder which requires prior demand upon Company, the commencement of a bankruptcy case or other insolvency or liquidation proceeding by or against Company shall automatically eliminate the necessity of such demand upon Company by Bank, and shall immediately entitle Bank to make demand on Secured Party with the same effect as if demand had been made upon Company and the time for Company’s performance had expired.

12.

Legal Process, Legal Notices and Court Orders. Bank will comply with any legal process, legal notice or court order it receives if Bank determines in its sole discretion that the legal process, legal notice or court order is legally binding on it.

13.

Indemnification for Following Instructions. Secured Party and Company each agree that, notwithstanding any other provision of this Agreement, Bank will not be liable to Secured Party or Company for any losses, liabilities, damages, claims (including, but not limited to, third party claims), demands, obligations, actions, suits, judgments, penalties, costs or expenses, including, but not limited to, attorneys’ fees, (collectively, “Losses and Liabilities”) suffered or


RestAcctAgmt-Std-NS		Page 3
(Revised 08/09/05)

incurred by Secured Party or Company as a result of or in connection with, (a) Bank complying with any binding legal process, legal notice or court order referred to in Section 12 of this Agreement, (b) Bank following any instruction or request of Secured Party, or (c) Bank complying with its obligations under this Agreement. Company will indemnify Bank against any Losses and Liabilities Bank may suffer or incur as a result of or in connection with any of the circumstances referred to in clauses (a) through (c) of this Section 13. To the extent not paid by Company within thirty (30) calendar days after written demand, Secured Party will indemnify Bank against any Losses and Liabilities Bank may suffer or incur as a result of or in connection with any of the circumstances referred to in clause (b) of this Section 13. Notwithstanding anything to the contrary contained herein, no party shall be entitled to the benefits of this Section 13 to the extent of any bad faith, gross negligence or willful misconduct by such party seeking indemnification.

14.

No Representations or Warranties of Bank. Bank agrees to perform its obligations under this Agreement in a manner consistent with the quality provided when Bank performs similar services for its own account. However, Bank will not be responsible for the errors, acts or omissions of others, such as communications carriers, correspondents or clearinghouses through which Bank may perform its obligations under this Agreement or receive or transmit information in performing its obligations under this Agreement. Secured Party and Company also understand that Bank will not be responsible for any loss, liability or delay caused by wars, failures in communications networks, labor disputes, legal constraints, fires, power surges or failures, earthquakes, civil disturbances or other events beyond Bank’s control. BANK MAKES NO EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES WITH RESPECT TO THE SERVICE OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT.

15.

Limitation of Liability. Bank will not be responsible for any Losses and Liabilities due to any cause other than its own negligence or breach of this Agreement, in which case its liability to Secured Party and Company shall, unless otherwise provided by any law which cannot be varied by contract, be limited to direct money damages in an amount not to exceed ten (10) times all the Bank Fees charged or incurred during the calendar month immediately preceding the calendar month in which such Losses and Liabilities occurred (or, if no Bank Fees were charged or incurred in the preceding month, the Bank Fees charged or incurred in the month in which the Losses and Liabilities occurred). Company will indemnify Bank against all Losses and Liabilities suffered or incurred by Bank as a result of third party claims; provided, however, that Company shall not indemnify to extent such Losses and Liabilities arise from gross negligence, bad faith or willful misconduct from such party seeking indemnification. IN NO EVENT WILL BANK BE LIABLE FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES, WHETHER ANY CLAIM IS BASED ON CONTRACT OR TORT, WHETHER THE LIKELIHOOD OF SUCH DAMAGES WAS KNOWN TO BANK AND REGARDLESS OF THE FORM OF THE CLAIM OR ACTION, INCLUDING, BUT NOT LIMITED TO, ANY CLAIM OR ACTION ALLEGING GROSS NEGLIGENCE, WILLFUL MISCONDUCT, FAILURE TO EXERCISE REASONABLE CARE OR FAILURE TO ACT IN GOOD FAITH. Any action against Bank by Company or Secured Party under or related to this Agreement must be brought within twelve (12) months after the cause of action accrues.

16.

Termination. This Agreement and the Service may be terminated by Secured Party or Bank at any time by either of them giving thirty (30) calendar days prior written notice of such termination to the other parties to this Agreement at their contact addresses specified after their signatures to this Agreement; provided, however, that this Agreement and the Service may be terminated immediately upon written notice from Bank to Company and Secured Party should Company or Secured Party fail to make any payment when due to Bank from Company or Secured Party under the terms of this Agreement.

(Revised 08/09/05)

report errors in funds transfers and bank statements and to pay Returned Item Amounts and Bank Fees, as well as the indemnifications made, and the limitations on the liability of Bank accepted, by Company and Secured Party under this Agreement will continue after the termination of this Agreement and/or the closure of the Restricted Account with respect to all the circumstances to which they are applicable existing or occurring before such termination or closure, and any liability of any party to this Agreement, as determined under the provisions of this Agreement, with respect to acts or omissions of such party prior to such termination or closure will also survive such termination or closure.

Any notice sent by a party to this Agreement to another party shall also be sent to all other parties to this Agreement. Bank is authorized by Company and Secured Party to act on any instructions or notices received by Bank if (a) such instructions or notices purport to be made in the name of Secured Party, (b) Bank reasonably believes that they are so made, and (c) they do not conflict with the terms of this Agreement as such terms may be amended from time to time, unless such conflicting instructions or notices are supported by a court order.

Bank may not assign its rights or obligations under this Agreement to any person or entity without the prior written consent of Secured Party, which consent will not be unreasonably withheld; provided, however, that no such consent will be required if such assignment or transfer takes place as part of a merger, acquisition or corporate reorganization affecting Bank.

20.

Governing Law. Company and Secured Party understand that Bank’s provision of the Service under this Agreement is subject to federal laws and regulations.

Section 6.3

Litigation

On April 24, 2006, a class action complaint was filed in the US District Court for the Eastern District of Louisiana, on behalf of citizens of Louisiana who suffered property damage from the waters that flooded New Orleans after Hurricane Katrina hit the area. The suit names Great Lakes Dredge & Dock Company, LLC (the “Company”) along with numerous other dredging companies who have completed projects on behalf of the Army Corps of Engineers in the Mississippi River Gulf Outlet (“MRGO”), and the Federal government as defendants. The complaint alleges that dredging of MRGO caused the destruction of the Louisiana wetlands which provide a natural barrier against storms and hurricanes. This loss of natural barriers then contributed to the failure of the levees upon the impact of Hurricane Katrina which allowed the floodwaters to damage plaintiffs’ property. Among other assertions is negligence in violation of the Water Pollution Control Act. The amount of damages is not stated but would be presumed to be significant. The Company believes it has meritorious defenses and believes this claim will not have a material adverse impact on the Company’s business.

On February 10, 2004, the Company was served with a subpoena to produce documents in connection with a federal grand jury convened in the United States District Court for the District of South Carolina. The Company believes the grand jury has been convened to investigate the United States dredging industry in connection with work performed for the U.S. Army Corp of Engineers. The Company complied with the Justice Department’s requests and Company management believes that it has provided substantially all of the documents that have been requested to this point. In addition to the documents requested, seven employees or former employees of the Company have now been interviewed or have testified before the grand jury.

On January 19, 2005, the Company, along with its joint-venture partners on the Port of Los Angeles Deepening Project, received a request for information from the United States Environmental Protection Agency (“EPA”) pursuant to section 308(a) of the Clean Water Act. The EPA is investigating alleged dredging of unauthorized material and unauthorized discharge of that material at various locations in federally regulated waters of the U.S. relating to this project. The Company performed this project under a contract with the Los Angeles district of the Corps and believes it was in compliance with the contract specifications. The Company has complied with the request for information and has received no further response from the EPA. It is management’s understanding that the Corps is currently addressing this matter with the EPA in Washington, as this is a national policy issue. Therefore, the Company believes the EPA request it has received will not result in any further action against the Company.

Schedule 6.3

Litigation

The Company or its former subsidiary, NATCO Limited Partnership, are named as defendants in approximately 280 lawsuits, the majority of which were filed between 1989 and 2000, and 18 of which were filed in the last three years. In these lawsuits, the plaintiffs allege personal injury, primarily fibrosis or asbestosis, from exposure to asbestos on our vessels. The vast majority of these lawsuits have been filed in the Northern District of Ohio and a few in the Eastern District of Michigan. All of the cases filed against the Company prior to 1996 were administratively dismissed in May 1996 and any cases filed since that time have similarly been administratively transferred to the inactive docket. Plaintiffs in these cases could seek to reinstate the cases at a future date without being barred by the statute of limitations. However, to date, no plaintiffs with claims against the Company have sought reinstatement. There are therefore no active pending cases against the Company. The Company believes that these cases will not have a material adverse impact on the Company’s business.
