Board of Directors

L. W. Matteson, Inc.

Burlington, Iowa

We have audited the accompanying balance sheet of L. W. Matteson, Inc. as of December 31, 2009, and the related statements of income, stockholders’ equity, and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. The financial statements of L. W. Matteson, Inc. as of and for the year ended December 31, 2008, were audited by other auditors whose report dated June 1, 2009, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of L. W. Matteson, Inc. as of December 31, 2009, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

Note 1.

Nature of Business

L. W. Matteson, Inc. (Company) is a river dredging and marine construction contractor, operating throughout the United States. The construction work is performed primarily under fixed-price contracts. Credit is extended to qualified customers on an unsecured basis.

Note 2.

Summary of Significant Accounting Policies

Basis of Accounting

The financial statements are prepared under the accrual method of accounting.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist of deposits in checking, money market and savings accounts, and certificates of deposit with original maturities of 90 days or less. The Company maintains substantially all of its funds in one financial institution, and the balance at times may exceed FDIC-insured limits.

Construction Contracts Receivable

Contracts receivable are recorded as invoiced based on contracted prices. Normal contracts receivable are due 30 days after invoices are issued. Contract retentions are due 30 days after substantial completion of the project and acceptance by the owner. Receivables past due more than 90 days are considered delinquent. The Company provides an allowance for doubtful accounts when it is determined that an amount is not likely to be collected. This allowance is based upon a review of outstanding receivables, historical collection information and existing economic conditions. At December 31, 2009, the Company did not have an allowance for doubtful accounts. Receivables are written off based on individual credit evaluation and specific circumstances of the customer. The Company had no bad debt expense for the year ended December 31, 2009.

Property and Equipment

Property and equipment is carried at original cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the assets, which range from 3 to 40 years. Depreciation expense for the year ended December 31, 2009 totaled $2,889,493.

Summary of Significant Accounting Policies (continued)

Revenue and Cost Recognition

The Company recognizes revenues from fixed-price and modified fixed-price construction contracts under the percentage-of-completion method, measured by the percentage of cost incurred to date compared to estimated total cost for each contract. The percentage-of-completion method is used because management considers total cost to be the best available measure of progress on the contracts. Because of inherent uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change within the near term.

Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation. General and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, contract penalty provisions, claims, change orders, settlements and estimated profitability may result in revisions to costs and income, which are recognized in the period in which the revisions are determined.

The asset, “Costs and estimated earnings in excess of billings on uncompleted contracts”, represents revenues recognized in excess of amounts billed. The liability, “Billings in excess of costs and estimated earnings on uncompleted contracts”, represents billings in excess of revenues recognized.

Income Taxes

The Company, with the consent of its stockholders, has elected to be taxed under sections of the federal and state income tax laws which provide that, in lieu of corporation income taxes, the stockholders separately account for their pro-rata shares of the Company’s items of income, deductions, losses and credits. Therefore, these financial statements do not include any provision for corporation income taxes. The Company declares dividends and pays bonuses from time to time to assist stockholders in paying income tax liabilities that result from their pro-rata share of the Company’s income.

The Company has open tax years for three years prior to December 31, 2009. The Company records interest and penalties, if any, in general and administrative expenses.

Recent Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation Number 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109 (FASB Accounting Standards Codification 740-10), which provides detailed guidance for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in an entity’s financial statements in accordance with professional standards. The standard also requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. A nonpublic entity could elect to defer its application of this professional standard to annual financial statements for fiscal years beginning after December 15, 2008. The Company elected to defer the adoption of this professional standard until January 1, 2009. The Company completed its analysis of the effects of this professional standard during the year and did not identify any uncertain tax positions. Accordingly, the adoption of the standard did not have a material impact on its financial statements.

Commitments and Contingent Liabilities

Various lawsuits, claims, and proceedings have been or may be instituted or asserted against the Company relating to the conduct of its business, including those pertaining to dredging and construction contracts, safety and health, and employment matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims, and proceedings may be disposed of unfavorably to the Company, management believes the disposition of matters which are pending or asserted will not have a materially adverse effect on the Company’s financial statements.

Note 9.

Basis of Accounting

The financial statements are prepared under the accrual method of accounting.

Use of Estimates

Cash and Cash Equivalents

Construction Contracts Receivable

Contracts receivable are recorded as invoiced based on contracted prices. Normal contracts receivable are due 30 days after invoices are issued. Contract retentions are due 30 days after substantial completion of the project and acceptance by the owner. Receivables past due more than 90 days are considered delinquent. The Company provides an allowance for doubtful accounts when it is determined that an amount is not likely to be collected. This allowance is based upon a review of outstanding receivables, historical collection information and existing economic conditions. At September 30, 2010, the Company did not have an allowance for doubtful accounts. Receivables are written off based on individual credit evaluation and specific circumstances of the customer. The Company had no bad debt expense for the nine-month periods ended September 30, 2010 and 2009.

Summary of Significant Accounting Policies (continued)

Revenue and Cost Recognition

The Company recognizes revenues from fixed-price construction contracts under the percentage-of-completion method, measured by the percentage of cost incurred to date compared to estimated total cost for each contract. The percentage-of-completion method is used because management considers total cost to be the best available measure of progress on the contracts. Because of inherent uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change within the near term.

Income Taxes

The Company has open tax years for three years prior to December 31, 2009. The Company records interest and penalties, if any, in general and administrative expenses.

Note 3.

Note Receivable

During the year ended December 31, 2003, the Company accepted an unsecured note receivable as part of a settlement agreement with a vendor. The agreement requires the vendor to make annual principal payments in various amounts, plus interest at prime rate through May 1, 2010. The note was paid in full during the period ended September 30, 2010. Related interest income totaled $1,897 and $3,508 for the periods ended September 30, 2010 and 2009, respectively.

1. Basis of Pro Forma Presentation

On December 31, 2010, Great Lakes Dredge & Dock Company LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (the "LLC"), entered into and consummated an Asset Purchase Agreement with L.W. Matteson, Inc., an Iowa corporation, and Lawrence W. Matteson and Larry W. Matteson pursuant to which the LLC purchased for a base purchase price of $45,000 (a) the business and substantially all of the assets of Seller and (b) certain assets owned by Lawrence W. Matteson and used by the Seller in its business. The purchase price totaled $47,009 and included an adjustment based upon the closing working capital balance, which resulted in the recognition of additional purchase price of $369 and is subject to further adjustment in accordance with the Asset Purchase Agreement. Furthermore, the seller may receive cash payments for any of the calendar years ended 2011, 2012, and 2013 if certain earnings-based criteria, defined per the purchase agreement, are met. The fair value of the recorded earnout liability was $1,640. The transaction was accounted for using the acquisition method and as such Matteson’s assets acquired and liabilities assumed have been recorded at their fair value. Great Lakes Dredge & Dock Company, LLC was determined to be the accounting acquirer for purposes of these unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined balance sheet as of September 30, 2010 gives effect to the acquisition as if it occurred on that date.

For purposes of these unaudited pro forma condensed combined financial statements, the estimated purchase price paid by the LLC has been allocated to Matteson’s assets and liabilities based on their fair values as of December 31, 2010 as follows (in thousands):
