This Annual Report pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, including but not limited to the Management’s Discussion and Analysis of Financial Condition and Results of Operations, contains or may contain forward-looking statements as such term is defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Readers are cautioned not to place undue reliance on such statements because they are subject to numerous uncertainties and factors relating to the Company’s operations and business environment, all of which are difficult to predict and many of which are beyond the Company’s control. Forward-looking statements include information concerning the Company’s possible or assumed future results of operations. When used in this Report, the words “anticipate,” “believe,” “estimate,” “expect,” “future,” “intend,” “plan,” “should” and similar expressions or the negative thereof or other comparable terminology or discussions of strategy, plans, or intentions, identify such forward-looking statements. These statements are based on assumptions that have been made in light of the Company’s experience in the industry as well as its perceptions of historical trends, current conditions, expected future developments and other factors that the Company believes are appropriate under the circumstances. These statements are not guarantees of performance or results. Although the Company believes that these forward-looking statements are based on reasonable assumptions, many factors could affect the Company’s actual financial results or results of operations and could cause actual results to differ materially from those in the forward-looking statements. Some of these factors include:

•A loss of government dredging contracts could have a negative impact on the Company’s business, financial condition and results of operation.

•The Company’s dredging revenues are heavily dependent on revenues from the Army Corps of Engineers and may be negatively impacted by reductions in the amount appropriated or funded for dredging services.

•Significant operating risks and hazards (including environmental hazards, industrial accidents, encountering unusual or unexpected geological formations, cave-ins below water levels, disruption of transportation services and flooding) could result in damage or destruction to persons or property, which could result in losses or liabilities to the Company.

•Although the Company insures against the risk of loss in its business, actual liabilities may exceed the Company’s insurance coverage.

•The Company’s inability to obtain bonding for future projects would limit the amount of dredging contracts that the Company could perform.

•The Company’s growth may be hindered if it is unable to retain key executives and other personnel.

•The Company is exposed to political, economic and other risks related to its international operations.

•The Company’s operations may be adversely affected by weather conditions and natural disasters.

1

•The amount of the Company’s estimated backlog is subject to change and not necessarily indicative of future sales.

•Because of the fixed-price nature of most of its contracts, the Company is subject to risks of losses from underestimating costs, operational difficulties and other changes that may occur over the contract period.

•The Company’s dredging operations may fluctuate due to seasonality and other factors that may adversely affect its cash flow.

•The Company’s business could suffer in the event of a work stoppage by its unionized labor force.

•Environmental matters could force the Company to incur significant capital and operational costs.

•If the Company’s demolition business is unable to compete effectively, its demolition revenues may decline and it may be unable to sustain its gross profit margins in its demolition business.

•The loss of key customers and large contracts in its demolition activities could have a material impact on the Company’s business, financial condition and results of operations.

•The Company depends on subcontractors in its demolition business, and an inability to find quality subcontractors could cause disruptions in its demolition business.

Other factors and assumptions not identified above are also relevant to the forward-looking statements, and if they prove incorrect, could also cause actual results to differ materially from those projected. The forward-looking statements made in this Report or incorporated by reference into this Report relate only to events as of the date on which the statements are made. The Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events.

Part I

Item  1. - Business

Organization

Great Lakes Dredge & Dock Corporation (the “Company” or “Great Lakes”), a Delaware corporation, is the largest provider of dredging services in the United States. The Company was founded in 1890 as Lydon & Drews Partnership and contracted its first project in Chicago, Illinois. The Company changed its name to Great Lakes Dredge & Dock Company in 1905 and was involved in a number of marine construction and landfill projects along the Chicago lakefront and in the surrounding Great Lakes’ region. The Company was listed on the NYSE in 1971, and in 1985, purchased through a friendly stock offer by ITEL. Throughout this period, the Company expanded geographically, providing marine construction and dredging services throughout the U.S. and in certain international markets. In 1991, the Company was purchased by an affiliate of Blackstone Capital Partners, who owned the Company until 1998, at which

2

time it was sold to Vectura Holding Company LLC (“Vectura”), a portfolio company of Citigroup Venture Capital, Ltd.

On December 22, 2003, Madison Dearborn Capital Partners IV, L.P. (“MDP”), an affiliate of Chicago-based private equity investment firm Madison Dearborn Partners, LLC, acquired control of Great Lakes from its former owner, Vectura, for approximately $361.6 million, including fees and expenses, in a transaction accounted for as a purchase. The acquisition was effected by a new company established for this purpose, GLDD Acquisitions Corp., which acquired 100% of the equity securities of the Company. Certain members of GLDD’s management own approximately 15% of outstanding common stock of GLDD Acquisitions Corp. and MDP and certain of its co-investors own the remaining 85%. The acquisition was financed by new equity contributions of $97.0 million; term loan and revolver borrowings under a new senior credit facility of $60.3 million and $2.0 million, respectively; the issuance of $175.0 million of 7¾% senior subordinated notes due 2013; the rollover of term loan borrowings under a new equipment financing facility of $23.4 million; the rollover of approximately $1.6 million of capital leases; and cash on hand of $2.3 million.

On April 24, 2001, the Company purchased 80% of the capital stock of North American Site Developers, Inc. (“NASDI”), a demolition services provider located in the Boston, Massachusetts area. The purchase consideration for the acquisition included $35.0 million in cash payable to the stockholders of NASDI and two senior subordinated notes totaling $3.0 million payable to the NASDI management stockholders. In 2003, the Company increased its ownership in NASDI to 85%. One NASDI management stockholder retains a 15% non-voting interest in NASDI. With the acquisition of NASDI, the Company now operates in two reportable segments: dredging and demolition. Financial information about the Company’s segments is provided in Note 17, “Segment information” in the Notes to the Consolidated Financial Statements.

Dredging Operations

Dredging generally involves the enhancement or preservation of navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. The U.S. dredging market consists of three primary types of work: capital, beach nourishment and maintenance. The Company’s bid market is defined as the population of projects on which it bid or could have bid if not for capacity constraints (“bid market”). The Company achieved a combined U.S. market share of the projects awarded within its bid market of 31%, 43% and 31% in 2005, 2004 and 2003, respectively. In addition, the Company is the only U.S. dredging service provider with significant international operations, which averaged 16% of its dredging contract revenues over the last three years. The Company’s fleet of 26 dredges, 24 material transportation barges, two drillboats, and numerous other specialized support vessels is the largest and most diverse fleet in the U.S. The Company believes its fleet would cost in excess of $1.0 billion to build in the current market.

Domestic Dredging Operations. Over its 115-year life, the Company has grown to be a leader in each of its primary dredging activities in the U.S., including:

•Capital (approximately 43% of 2005 dredging revenues). Capital dredging projects are primarily port expansion projects, which involve the deepening of channels to allow access by larger, deeper draft ships and the providing of land fill for building additional port facilities. Capital projects also include other land reclamations, trench digging for pipes, tunnels and cables, and other dredging related to the construction of breakwaters, jetties, canals and other marine structures. Although capital revenue can be impacted by budgetary constraints and economic conditions, these projects typically generate an immediate economic benefit to the ports and surrounding communities. The Company’s bid market share of total U.S. capital projects averaged 41% over the last three years.

The U.S. capital market includes “Deep Port” projects authorized under the 1986 Water Resource Development Act (“WRDA”) as amended and supplemented, most recently in December 2000. Without significant deepening efforts, many major U.S. ports risk losing their competitive position as a result of being unable to accommodate larger cargo vessels. The WRDA legislation provides the authorization for federal funding for the deepening of these major domestic ports. Since 1997, supplemental WRDA bills have authorized Deep Port work with an aggregate value in excess of $4.0 billion. There is a significant portion of this work remaining to be completed to date and should provide continuing port deepening into the future. Deep Port work has comprised a substantial portion of recent bid markets, averaging 20% of the bid market over the last three years. The Company’s bid market share of Deep Port projects averaged 53% over the last three years.

•Beach Nourishment (approximately 25% of 2005 dredging revenues). Beach nourishment projects generally involve moving sand from the ocean floor to shoreline locations when erosion has progressed to a stage that threatens substantial shoreline assets. Beach nourishment is often viewed as a better response to erosion than trapping sand through the use of sea walls and jetties, or relocating buildings and other assets from the shoreline. Beach nourishment also facilitates shoreline real estate development and recreational activities. Generally, beach nourishment projects take place during the fall and winter months to minimize interference with bird and marine life migration and breeding patterns and coastal recreation activities. The Company’s bid market share of U.S. beach nourishment projects averaged 46% over the last three years.

•Maintenance (approximately 19% of 2005 dredging revenues). Maintenance dredging consists of the re-dredging of previously deepened waterways and harbors to remove silt, sand and other accumulated sediments. Due to natural sedimentation, active channels generally require maintenance dredging every one to three years, thus creating a recurring source of dredging work that is typically non-deferrable if optimal navigability is to be maintained. The Company’s bid market share of U.S. maintenance projects averaged 24% over the last three years.

Foreign Dredging Operations (approximately 13% of 2005 dredging revenues). Foreign capital projects typically relate to channel deepening and port infrastructure development. Beginning in the early 1990s, consolidation among foreign competitors, along with an increase in foreign governments’ investments in infrastructure, created new overseas dredging opportunities for the

4

Company. Since this time, the Company has targeted opportunities that are well suited to its equipment and where competition from its European competitors is reduced. While the Company has only a minor share of the international dredging market, it has maintained its presence in the foreign markets to enable it to diversify, particularly at times when there is anticipation of a decrease in the domestic market. Over the last ten years, the Company has worked in Europe, the Middle East, Africa, India, Mexico and South America. In recent years, the Middle East region has presented the most attractive prospects. Therefore, the Company currently has certain dredging assets located in Middle East; however, these assets are mobile and may be repositioned according to project requirements. Revenues from foreign capital projects averaged 16% of the Company’s dredging revenues over the last three years.

The Company believes that it benefits from a number of long-term favorable trends in the U.S. dredging market:

•Deep Port capital projects. Historically, the average controlling depth of the 10 largest U.S. ports has been 40 feet, as measured by annual container volume, compared to over 50 feet for the ten largest non-U.S. ports worldwide. Without continuing significant deepening efforts, most major U.S. ports risk being unable to accommodate the larger cargo vessels increasingly in use throughout the world, which renders them less competitive with deeper ports. Funding for Deep Port projects has represented a significant portion of recent years’ markets, and the Company continues to believe that Deep Port work will provide significant opportunities for the domestic dredging industry.

•Increasing need for beach nourishment. Beach erosion is a continuous problem and there is a growing awareness among state and local governments as to the importance of beachfront assets to the multi-billion dollar tourism industry. Beach projects are generally funded by both federal and state and local monies; therefore, a downturn in the economy can impact the amount of available funding, particularly from state and local sources. The recent annual beach bid markets, however, have grown due to effects of severe storm activity, especially in Florida. The annual bid market over the last three years has averaged $168 million, and current bid schedules provided by project owners identify beach projects for 2006 bidding valued in excess of $120 million.

•Additional significant long-term opportunities. Other capital projects make consistent contributions to the Company’s annual revenues, and, although not part of the Deep Port program, require similar technical expertise and equipment capabilities. For instance, the Company has just started its first project to provide ship access to a new liquified natural gas (“LNG”) terminal at Freeport, Texas. Also, the Company has submitted proposals for over $50 million in dredging services to private customers for development of additional terminals along the Gulf Coast of Texas. This private market appears to be gaining momentum as the global supply of LNG has increased and importation of the fuel becomes more cost-competitive, due to the higher prices of domestically-produced natural gas. Therefore, it is likely that this work will provide supplemental opportunities in the near term as the private contractors work to develop the infrastructure necessary for the LNG terminals. Additionally, there is anticipated to be significant capital dredging opportunities related to projects to contain the erosion of wetlands and coastal marshes particularly in Louisiana (“Louisiana Coastal Restoration”) and clean-up contaminated inland waterways such as the Fox River in Wisconsin and the Hudson River in New York. These long-term projects have

5

the potential to add substantial revenue to the dredging market for approximately the next eight to 10 years.

While these market trends have represented key opportunities within the domestic dredging industry over the past 10 years and are expected to represent the key opportunities for the Company over at least the next 10 years, the domestic industry has experienced some negative funding developments over the past couple of years. Beginning in the second half of 2003 and into the first half of 2004, the domestic dredging bid activity declined. Although the Corps’ fiscal year 2003 and 2004 budgets were approved at similar levels to preceding years, it appeared that funds were not being distributed to the Corps’ districts. Based on conversations with Corps’ representatives and others in the industry, the Company’s management attributed the decline to budgetary pressures given the state of the deficit and the diversion of funds to support the nation’s efforts in Iraq. Additionally, during this time period the Corps underwent a reorganization of certain of its administration functions which also delayed its ability to request and receive funding. As a result of these funding issues, the industry’s dredging fleet was underutilized through much of 2004, leading to intense competition and pricing pressures for work that was bid during this period. Although the bidding activity levels improved towards the end of 2004 and throughout 2005, the industry did not have confidence in the market, and continued to bid very aggressively to gain utilization. In the fourth quarter of 2005, as the industry’s backlog improved, the pricing finally began to moderate, although pricing has not recovered to the levels seen prior to 2004.

Another concern that has been developing due to the funding constraints at the Corps is the issue of continuing contracts. There is a push by Congress to only allow projects to go forward that are fully funded. In the past, a project could be bid if there were appropriations for the current year only and the contract could be continued into the next year. The remaining funding would be taken out of the following years’ appropriations. If continuing contracts are not allowed, this will become an obstacle to the Corps in getting work out, especially on longer term projects. Management believes this work will ultimately be bid; however, this does present an additional disruption in the orderly flow of activity in the bid market.

Also in 2004, there were renewed efforts by the federal government to eliminate the federal portion of beach nourishment funding. While in 2005 the beach nourishment market benefited from emergency supplemental federal funding to address the damage caused by the severe hurricane season in 2004, there continues to be uncertainly regarding federal funding for this work. However, there are a number of projects now being sponsored by localities in Florida that have secured funding for their beach nourishment requirements through bond issues and taxes, since they recognize the cost/benefit to performing this work. As more municipalities devise a means to fund their individual projects, this will help to sustain the beach nourishment market even if the federal government reduces its commitment.

In summary, the dredging market has been in a state of disorder unlike the industry has seen over the past ten years or more. And while there are a number of factors contributing to uncertainty regarding project funding and timing, one overriding positive fact remains, and that is the need for dredging work remains. At some point in the future, all the work deferred currently will need to be performed. The Deep Port projects underway are not fully functional until all parts of the channels are taken to their final depths, and other authorized projects have been proven to be necessary to accommodate the deeper draft vessels in use throughout the world. Similarly, the

6

maintenance dredging, if not performed currently, will accumulate and grow in volume as channels continue to fill with sedimentation, eventually to the point were ships can no longer safely navigate into the ports, and beach nourishment work will reach a point of urgency as waterfront assets and recreational communities become jeopardized. Therefore, Company management believes that the current environment represents only a deferral of work, and not a permanent downturn in the industry.

Demolition Operations

NASDI, founded in 1976, is a major U.S. provider of commercial and industrial demolition services. The majority of NASDI’s work is performed in the New England area; however NASDI recently expanded into Florida and is pursuing opportunities in that market as well. NASDI’s core business is exterior and interior demolition. Exterior demolition involves the complete dismantling and demolition of structures and foundations. Interior demolition involves removing specific structures within a building. Other business activities include site development and asbestos and other hazardous material removal. NASDI generally contracts hazardous material removal to insured subcontractors and does not take possession of hazardous materials, which remain the property of the site owner. In a given year, NASDI performs numerous small projects (each generating revenue of $0.1 million to $0.5 million) but NASDI is one of a few providers in New England with the required licenses, operating expertise, equipment fleet and access to bonding to execute larger, complex industrial demolition projects. For instance, in recent years, NASDI has successfully performed three large demolition projects involving the dismantling and disposal of aging power generation plants, as well as large projects at Logan Airport and various Boston-area office buildings and former manufacturing facilities.

Competitive Strengths

The Company possesses a number of competitive strengths that have allowed it to develop and maintain its leading position within the dredging industry.

•Favorable competitive dynamic. The Company benefits from significant advantages relative to both existing and potential competitors, including (i) the requirements of the Foreign Dredge Act of 1906 (the “Dredging Act”) and Section 27 of the Merchant Marine Act of 1920 (the “Jones Act”), which effectively prohibit foreign dredges and, to a certain extent, foreign-owned dredging companies from competing in the U.S (see “Business – Government Regulations”); (ii) the relatively long lead time and high capital cost associated with the construction of a new dredge, which the Company estimates to be two years and between $20 to $60 million, depending on the type of dredge; and (iii) the Company’s reputation for quality and customer service built up over its 115-year operating history, during which time it has never failed to complete a project.

•Largest and most diverse dredging fleet. The Company operates the largest and most diverse dredging fleet in the U.S., with over 200 pieces of equipment, including the largest hopper fleet and the largest hydraulic dredges in the U.S. The size, versatility and technical capabilities of the fleet improves the Company’s competitiveness by affording the Company the flexibility to select the most efficient equipment for a particular job and

7

enabling the Company to perform multiple projects at the same time. To maintain the value and effectiveness of its fleet, the Company emphasizes preventative maintenance to minimize downtime, increase profitability, extend vessel life and reduce replacement capital expenditure requirements.

•Specialized capability in capital projects. The Company has also been a leader in U.S. capital dredging, which generally requires specialized engineering expertise, specific combinations of equipment and experience in executing complex projects. The Company believes its extensive experience performing complex projects significantly enhances its ability to bid for and complete these contracts profitably. Additionally, the Company believes it has a significant advantage over its competitors in projects bid as “requests for proposal”. For further information regarding the request for proposal process, see “– Bidding Process.”

•Proprietary and proven project costing methodologies. Over the course of its 115-year operating history, the Company has developed an extensive proprietary database of publicly-available dredging production records from its own and its competitors’ activities and past bidding results. The Company believes that its extensive proprietary database combined with its accumulated estimating and bidding expertise is a significant competitive advantage in bidding for new dredging contracts.

•Diversified revenue base. The Company benefits from a dredging revenue base that is broadly diversified across the three dredging sectors, which have different demand drivers. Capital projects primarily consist of port expansion work, which is driven by maintaining competitiveness between ports and growth in U.S. trade and commerce. Beach nourishment and maintenance projects are more heavily influenced by weather and recurring natural sedimentation and erosion. Revenue within each of the Company’s dredging sectors comes from a portfolio of separate contracts, which helps to mitigate project-specific risk. For the year ended December 31, 2005, the Company’s dredging revenues were derived from over 50 separate dredging contracts, and no one contract represented more than 10% of its revenues. The Company’s foreign dredging operations and demolition operations further diversify its revenue and customer base.

•Proven, experienced management team. The Company’s top executive management team has an average of 20 years of experience in the dredging industry. The Company believes that this experience provides it with a significant advantage over its competitors. Certain members of management own approximately 15% of the Company’s common stock.

Customers

Dredging. The dredging industry’s customers include federal, state, and local governments, foreign governments, and both domestic and foreign private concerns such as utilities and oil companies. Most dredging projects are competitively bid, with the award going to the lowest qualified bidder. There are generally few economical substitutes that customers can use for dredging services. The Corps is the largest dredging customer in the U.S. and has responsibility for federally funded projects related to navigation and flood control. In addition, the U.S. Coast

8

Guard and the U.S. Navy are responsible for awarding federal contracts with respect to their own facilities. In 2005, approximately 79% of the Company’s dredging revenues were earned from contracts with federal government agencies or companies operating under contracts with federal government agencies.

Foreign governments are the primary dredging customers in international markets, generally for capital projects relating to infrastructure development. Approximately 13% of the Company’s 2005 dredging revenues were earned from contracts with foreign governments or companies operating under contracts with foreign governments.

Demolition. NASDI’s customers include general contractors who subcontract demolition services, corporations that commission projects, non-profit institutions such as universities and hospitals, and local government and municipal agencies. NASDI benefits from key relationships with certain customers in the general contracting and public infrastructure industries. NASDI negotiates the majority of its demolition contracts as fixed price (“lump sum”) contracts with other projects negotiated on a time-and-materials (“T&M”) basis. NASDI frequently receives revenues from change orders on existing contracts. The majority of the demolition services are concentrated in New England, although NASDI now has limited operations in Florida as well. In 2005, no customer contributed more than 15% to NASDI’s annual revenues.

Bidding Process

Dredging. Most of the Company’s dredging contracts are obtained through competitive bidding on terms specified by the party inviting the bid. The nature of the specified services dictates the types of equipment, material and labor involved, all of which affect the cost of performing the contract and the price that dredging service providers will bid.

For contracts under its jurisdiction, the Corps typically prepares a cost estimate based on the specifications of the project. To be successful, a bidder must be determined by the Corps to be a responsible bidder (i.e., a bidder that generally has the necessary equipment and experience to successfully complete the project) and submit the lowest responsive bid that does not exceed 125% of an estimate determined by the Corps to be fair and reasonable. Contracts for projects that are not administered by the Corps are generally awarded to the lowest qualified bidder, provided the bid is no greater than the amount of funds that are available for the project.

Substantially all of the Company’s dredging contracts are competitively bid. However, some government contracts are awarded by a sole source procurement process through negotiation between the contractor and the government, while other projects have been recently bid by the Corps through a “request for proposal” (“RFP”) process. The RFP process allows the project award to be based on the technical capability of the contractor’s equipment and methodology, as well as price, and has, therefore, been advantageous for the Company since it has the technical engineering expertise and equipment versatility to comply with the project specifications.

Demolition. NASDI has established a network of local contacts with developers and prime contractors that act as referral sources and frequently enable NASDI to procure demolition jobs on a sole-source basis. When NASDI bids on a project, it evaluates the contract specifications and develops a cost estimate to which it adds profit for the final bid price. While there are

9

numerous competitors in the demolition services market, NASDI benefits from its relationships and reputation. Therefore, there are occasions where NASDI is not the lowest bidder on a contract, but is still awarded the project based on its reputation and qualifications.

Bonding and Foreign Project Guarantees

Dredging. For most domestic projects and some foreign projects, dredging service providers are required to obtain three types of bonds, which are typically provided by large insurance companies. A bid bond is required to serve as a guarantee that if a service provider’s bid is chosen, the service provider will sign the contract. The amount of the bond is typically 20% of the service provider’s bid, up to a maximum bond of $3.0 million. After a contract is signed, the bid bond is replaced by a performance bond, the purpose of which is to guarantee that the job will be completed. A performance bond typically covers 100% of the contract value with no maximum bond amounts. If the service provider fails to complete a job, the bonding company assumes such obligation and pays to complete the job, generally by using the equipment of the defaulting company. A company’s ability to obtain performance bonds with respect to a particular contract depends upon the size of the contract, as well as the size of the service provider and its financial position. A payment bond is also required to protect the service provider’s suppliers and subcontractors in the event that the service provider cannot make timely payments. Payment bonds are generally written at 100% of the contract value.

Great Lakes’ projects are currently bonded by Travelers Casualty and Surety Company of America (“Travelers”). The Company has never experienced difficulty in obtaining bonding for any of its projects. If the Company were to default on a project, the bonding company would complete the defaulted contract and would be entitled to be paid the contract price directly by the customer. Additionally, the bonding company would be entitled to be paid by the Company for any costs incurred in excess of the contract price. Travelers has been granted a security interest in a substantial portion of the Company’s operating equipment as collateral for its surety obligations.

For most foreign dredging projects, letters of credit or bank guarantees issued by foreign banks, which are secured by letters of credit issued under the Company’s credit agreement with its senior secured lenders (the “Credit Agreement”), are required as security for the bid, performance and, if applicable, advance payment. Foreign bid guarantees are usually 2% to 5% of the service provider’s bid. Foreign performance and advance payment guarantees are each typically 5% to 10% of the contract value.

Demolition. NASDI’s contracts are primarily with private, non-government customers; thus, it often is not required to secure bonding. When NASDI does have bonding requirements, the bonds are also provided by Travelers.

Competitive Environment

Dredging. Competition in the Company’s market is determined primarily on the basis of price, and competition is often limited by the size of the job, equipment requirements, bonding requirements, certification requirements, or government regulations. Great Lakes and four other

10

key competitors perform the majority of the work within the Company’s domestic dredging bid market. On average over the last three years, Great Lakes’ share of the market was 36% with the other four entities obtaining a 44% share. Since the Deep Port projects are typically of significant value and there is a large volume of projects remaining in the program, some additional competitors, (primarily smaller dredging companies or marine-oriented construction companies), have made equipment investments, rationalized by the opportunities in the Deep Port market and encouraged by the Corps in an effort to increase competition. While some of these other entities have won a few major Deep Port contracts, they generally do not have the capabilities to perform well on these projects; therefore, it is unclear if they will pose the same degree of competition in the future.

The Dredging Act and the Jones Act provide a significant barrier to entry with respect to foreign competition. Together the two regulations prohibit foreign-built, chartered or operated vessels from competing in the U.S. See “ – Government Regulations.”

One of the Company’s key competitors commissioned a new hopper dredge that most recently was performing sea trials and could enter the bid market in the first half of 2006. This dredge is over two-times the size of the Company’s most recently constructed hopper dredge, the Liberty Island, and is best suited for the maintenance rental market in the Mississippi Gulf Outlet. It is difficult to anticipate what the effect will be of the entrance of this dredge to the market. With the storm damage caused by the hurricanes Katrina and Rita there should be an increased need for dredging services in and around Louisiana and Mississippi and therefore, it is possible the bid market will be sufficient to absorb the capacity at the time. In general though, the dredge will create additional capacity at a time of uncertainty in market conditions. Another competitor is also looking to add capacity with a large clamshell bucket dredge, suited for harbor maintenance work. The vessel has been engineered but is not yet under construction. At this point, there is no known completion date but again, when it enters the market it will be additional capacity for which the need is not clear.

Demolition. The U.S. demolition and related services industry is also highly fragmented and is comprised mostly of small regional companies. Unlike many of its competitors, NASDI is able to perform both the small and large projects and competes in the demolition and related services industry primarily on the basis of its experience, reputation, equipment, key client relationships and price.

Equipment

Dredging. Great Lakes’ fleet of dredges, material barges and other specialized equipment is the largest and most diverse in the U.S. There are three principal types of dredging equipment:  hopper dredges, hydraulic dredges and mechanical dredges.

•Hopper Dredges. Hopper dredges are typically self-propelled and have the general appearance of an ocean-going vessel. The dredge has hollow hulls, or “hoppers”, into which material is suctioned hydraulically through drag-arms and deposited. Once the hoppers are filled, the dredge sails to the designated disposal site and either (i) bottom dumps the material or (ii) pumps the material from the hoppers through a pipeline to the designated site. Hopper dredges can operate in rough waters, are less likely than other types of dredges to interfere with ship traffic, and can move quickly from one project to another. Great Lakes operates

11

the largest hopper fleet in the U.S., affording it flexibility to quickly respond to time-sensitive projects.

•Hydraulic Dredges. Hydraulic dredges remove material using a revolving cutterhead which cuts and churns the sediment on the ocean floor and hydraulically pumps the material by pipe to the disposal location. These dredges are very powerful and can dredge some types of rock. Certain materials can be directly pumped as far as seven miles with the aid of a booster pump. Hydraulic dredges work with an assortment of support equipment, which help with the positioning and movement of the dredge, handling of the pipelines, and the placement of the dredged material. Great Lakes operates the only large electric hydraulic dredge in the U.S., which makes the Company particularly competitive in markets with stringent emissions standards, such as California and Houston.

•Mechanical Dredges. There are two basic types of mechanical dredges operating in the U.S.:  clamshell and backhoe. In all cases, the dredge uses a bucket to excavate material from the ocean floor. The dredged material is placed by the bucket into material barges, or “scows”, for transport to the designated disposal area. The scows are emptied by bottom-dumping, direct pump-out or removal by a crane with a bucket. Mechanical dredges are capable of removing hard-packed sediments and debris and can work in tight areas such as along docks or terminals. Clamshell dredges with specialized buckets are ideally suited to handle material requiring controlled disposal. The Company has the largest fleet of material barges in the industry, which provides cost advantages when dredged material is required to be disposed far offshore or when material requires controlled disposal. Additionally, the Company recently converted one of its clamshell dredges to electric power to better compete in those markets with stringent emissions standards.

Great Lakes’ domestic dredging fleet is typically positioned on the East and Gulf Coasts, with a smaller number of vessels on the West Coast and on inland rivers. The mobility of the fleet enables the Company to move equipment in response to changes in demand. Great Lakes’ fleet also includes assets currently positioned internationally in the Middle East.

The Company continually assesses its need to upgrade and expand its dredging fleet to take advantage of improving technology and to address the changing needs of the dredging market. The Company is also committed to preventive maintenance, which it believes is reflected in the long lives of most if its equipment and its low level of unscheduled downtime on jobs. As such, the Company spent an average of $27 million on maintenance and $18 million on capital additions and enhancements, annually over the last three years. During this period, the Company’s capital expenditures included $15 million to buy out certain operating equipment previously under operating lease, as well as $17 million on equipment that was funded from the proceeds of sale-leasebacks under operating leases or the proceeds from the sale of certain equipment under a like-kind exchange transaction. Therefore, in a typical year, the Company generally funds $13 to $18 million of capital expenditures with cash flow from its operations.

Demolition. NASDI owns and operates specialized demolition equipment, including a fleet of excavators equipped with shears, pulverizers, processors, grapples, and hydraulic hammers that provide high-capacity processing of construction and demolition debris for recycling and reclamation. NASDI also owns and maintains a large number of skid-steer loaders, heavy-duty large-capacity loaders, cranes, recycling crushers, off-highway hauling units and a fleet of tractor-trailers for transporting equipment and materials to and from job sites. NASDI rents

12

additional equipment on a project-by-project basis, which allows NASDI flexibility to adjust costs to the level of project activity.

Equipment Certification

Certification of equipment by the U.S. Coast Guard and establishment of the permissible loading capacity by the American Bureau of Shipping (“A.B.S.”) are important factors in Great Lakes’ dredging business. Many projects, such as beach nourishment projects with offshore sand borrow sites, dredging projects in exposed entrance channels, and dredging projects with offshore disposal areas, are restricted by federal regulations to be performed only by dredges or scows that have U.S. Coast Guard certification and a load line established by the A.B.S. The certifications indicate that the dredge is structurally capable of operating in open waters. The Company has more certified vessels than any domestic competitor and makes substantial investments to maintain these certifications.

Seasonality

Seasonality does not currently have a significant impact on the Company’s dredging operations. Some east coast beach nourishment projects are limited by environmental windows, which require that certain work be performed in winter months to protect wildlife habitats. However, in recent years, this has been mitigated by the increased volume of Deep Port work in the market, which can generally be performed throughout the year. The Company has been able to respond to these market factors since it has the flexibility to move its equipment around as environmental restrictions and project requirements dictate. However, in the future, seasonality may become more of a factor if the project mix changes and the Company is unable to be as flexible in utilizing its equipment. The Company’s demolition operations are not significantly impacted by seasonality.

Backlog

The Company’s contract backlog represents management’s estimate of the revenues which will be realized under the portion of the contracts remaining to be performed. Such estimates are subject to fluctuations based upon the amount of material actually dredged or scope of demolition services to be provided as well as factors affecting the time required to complete the job. In addition, because a substantial portion of the Company’s backlog relates to government contracts, the Company’s backlog can be canceled at any time without penalty; however, the Company can generally recover actual committed costs and profit on work performed up to the date of cancellation. Consequently, backlog is not necessarily indicative of future results. The Company’s backlog includes only those projects for which the customer has provided an executed contract. The components of the Company’s backlog are addressed in more detail in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Employees

Dredging. At December 31, 2005, the Company employed approximately 270 full-time salaried personnel, with additional U.S. hourly personnel, most of whom are unionized and hired on a project-by-project basis. During 2005, the Company employed an average of 500 hourly personnel to meet domestic project requirements. Crews are generally available for hire on relatively short notice. In addition, the Company employs approximately 21 expatriates and foreign nationals to manage and administer its overseas operations. The Company’s overseas crews are generally provided through an employment agreement with a company in the Philippines.

Demolition. At December 31, 2005, NASDI employed approximately 25 full-time salaried administrative employees, in addition to approximately 122 unionized employees who are party to four union agreements. The unionized employees are hired on a project-by-project basis and are generally available for hire on relatively short notice.

The Company is a party to numerous collective bargaining agreements in the U.S. that govern its relationships with its unionized hourly workforce. However, four primary agreements apply to approximately 84% of such employees. The Company’s contracts with Local 25 Operators Union for the northern and southern regions, representing approximately 51% of its unionized workforce, are set to expire in September 2006. The Company is in negotiations and expects to be able to renew the agreement in a timely manner without any significant impact to operations. The Company has not experienced any major labor disputes in the past five years and believes it has good relationships with its significant unions; however, there can be no assurances that the Company will not experience labor strikes or disturbances in the future.

Joint Ventures

Amboy Aggregates

The Company and a New Jersey aggregates company each own 50% of Amboy Aggregates (“Amboy”). Amboy was formed in December 1984 to mine sand from the entrance channel to the New York Harbor and to provide sand and aggregate for use in road and building construction. Great Lakes’ dredging expertise and its partner’s knowledge of the aggregate market formed the basis for the joint venture. The Company’s investment in Amboy is accounted for using the equity method.

Amboy is the only East Coast aggregate producer to mine sand from the ocean floor. Amboy has a specially designed dredge for sand mining, de-watering and dry delivery. No other vessel of this type operates in the U.S. Amboy’s ocean-based supply of sand provides a long-term competitive advantage in the Northeast as land-based sand deposits are depleted or rendered less cost competitive by escalating land values.

14

Mining operations are performed pursuant to permits granted to Amboy by the federal government and the states of New York and New Jersey. In 2002, Amboy was successful in obtaining approval for a new permit allowing it to mine deeper in its sand borrow areas. Amboy’s revenues have increased over the past three years due to improvement in the construction market, the primary market for Amboy’s product.

Government Regulations

The Company is subject to government regulations pursuant to the Dredging Act, the Jones Act, and the vessel documentation laws set forth in Chapter 121 of Title 46 of the United States Code (the “Vessel Documentation Act”). These statutes require vessels engaged in dredging in the navigable waters of the United States to be documented with a coastwise endorsement, to be owned and controlled by U.S. citizens, to be manned by U.S. crews, and to be built in the United States. The U.S. citizenship ownership and control standards require the vessel-owning entity to be at least 75% U.S.-citizen owned and prohibit the chartering of the vessel to any entity that does not meet the 75% U.S. citizen ownership test. These statutes, together with similar requirements for other sectors of the maritime industry, are collectively referred to as “cabotage” laws.

Certain of the above requirements were made applicable to the dredging industry in 1992, when Congress amended the Dredging Act to bring it into conformity with the U.S. citizenship requirements of the rest of the nation’s cabotage laws. At that time, Congress included grandfather clauses to protect certain existing dredge operations affected by the change in law. A grandfather provision exempted the hopper dredge STUYVESANT from the 75% ownership and control requirement. The STUYVESANT is chartered to Stuyvesant Dredging Company, Inc., a foreign corporation and wholly-owned subsidiary of Royal Boskalis Westminster, NV, a Dutch company, the largest dredging service provider in the world. In early 1999, the Stuyvesant Dredging Company exploited a loophole in grandfather provision and expanded its control of additional dredging vessels through a joint-venture, Bean Stuyvesant LLC, in which it has a 50% ownership interest. As of December 31, 2005, at least seven dredges plus other ancillary vessels operating in the United States were foreign controlled under this grandfather provision.

A coalition of U.S.-citizen dredging companies, labor unions, U.S. maritime operating companies and U.S. shipbuilders have joined together in an attempt to close the STUYVESANT grandfather clause loophole. In late 2003, one of the industry’s domestic dredging companies protested a bid award by the Corps in favor of Bean Stuyvesant LLC on the grounds that Bean Stuyvesant LLC was neither a U.S. citizen for the purpose of operating vessels in the coastwise trade nor eligible to charter the vessels at issue under the specific terms of the grandfather provision. The U.S. Court of Federal Claims agreed and enjoined the Corps from awarding the contract to Bean Stuyvesant LLC. On appeal, the U.S. Court of Appeals for the Federal Circuit overturned the Court of Federal Claims decision in the second quarter of 2004. And in 2005, the Supreme Court denied a writ of certiorari petitioned by a domestic competitor, which included a supporting amicus brief, filed on behalf of a broad coalition of domestic maritime interests to review the case. The marine industry will now have to turn to pursuing a legislative solution in this matter in an effort to ensure more equitable treatment among the industry participants.

15

Environmental Matters

The Company’s operations and facilities are subject to various environmental laws and regulations related to, among other things: dredging operations; the disposal of dredged material; protection of wetlands; storm water and waste water discharges; demolition activities; asbestos removal; transportation and disposal of other hazardous substances and materials; and air emissions. The Company is also subject to laws designed to protect certain marine species and habitats. Compliance with these statutes and regulations can delay appropriation with respect to, and performance of, particular projects and increase related expenses.

The Company’s projects may involve demolition, excavation, transportation, management and disposal of hazardous waste and other hazardous substances and materials. Various laws strictly regulate the removal, treatment and transportation of hazardous water and other hazardous substances and materials and impose liability for human health effects and environmental contamination caused by these materials. The Company’s demolition business, for example, requires it to transport and dispose of hazardous substances and materials, such as asbestos. The Company takes steps to limit its potential liability by hiring qualified asbestos abatement subcontractors to remove such materials from its projects, and some project contracts require the client to retain liability for hazardous waste generation.

Services rendered in connection with hazardous substance and material removal and site development may involve professional judgments by licensed experts about the nature of soil conditions and other physical conditions, including the extent to which hazardous substances and materials are present, and about the probable effect of procedures to mitigate problems or otherwise affect those conditions. If the judgments and the recommendations based upon those judgments are incorrect, the Company may be liable for resulting damages that its clients incur, which may be material.

Based on the Company’s experience, its management believes that the future cost of compliance with existing environmental laws and regulations (and liability for known environmental conditions) will not have a material adverse effect on its business, financial condition or results of operations. However, the Company cannot predict what environmental legislation or regulations will be enacted in the future; how existing or future laws or regulations will be enforced, administered or interpreted; or the amount of future expenditures that may be required to comply with these environmental or health and safety laws or regulations or to respond to future cleanup matters or other environmental claims. In January 2005, the Company received a request for information from the U.S. Environmental Protection Agency (the “EPA”), with respect to its Port of Los Angeles Deepening Project. See “Legal Proceedings” for additional information.

ITEM 1A. –Risk Factors

The Company depends on its ability to continue to obtain federal government dredging contracts, and is therefore greatly impacted by the amount of government funding for dredging projects. A reduction in government funding for dredging contracts can materially reduce the Company’s revenues and profits.

For the year ended December 31, 2005, approximately 79% of the Company’s dredging revenues were attributable to contracts with federal agencies or with companies operating under contracts with federal agencies. The Company’s dredging operations depend on project funding by various government agencies and are adversely affected by decreased levels of, or delays in, government funding. Beginning in the second half of 2003 and into the first half of 2004, the domestic dredging bid activity declined. Although the Corps’ fiscal year 2003 and 2004 budgets were approved at similar levels to the preceding years, it appeared that funds were not being distributed to the Corps’ districts. Based on conversations with Corps’ representatives and others in the industry, the Company’s management attributed the decline to budgetary pressures given the state of the deficit and the diversion of funds to support the nation’s efforts in Iraq. Additionally, during this time period the Corps underwent a reorganization of certain of its administration functions which also delayed its ability to request and receive funding.

As a result of these funding issues, the Company’s dredging fleet was underutilized through much of 2004, leading to intense competition and pricing pressures for work that was bid during this period. Although the bidding market improved in 2005, pricing remained competitive and is likely to remain competitive until industry participants regain confidence in the market. As a result of this competitive bidding, the Company’s share of work awarded in 2005 was 31%, which is below its historical average annual market share of the last five years of 41%.

The Company has a significant amount of indebtedness, which makes the Company more vulnerable to adverse economic and competitive conditions.

The Company has a significant amount of indebtedness. As of December 31, 2005, the Company had outstanding long-term indebtedness of approximately $249 million and stockholders’ equity of approximately $79 million. The Company’s substantial debt could:

•require the Company to dedicate a substantial portion of the Company’s cash flow from operations to payments on the Company’s indebtedness, thereby reducing the availability of the Company’s cash flow to fund working capital, capital expenditures and other general corporate purposes;

•limit the Company’s flexibility in planning for, or reacting to, changes in the Company’s business and the industry in which the Company operate;

•place the Company at a competitive disadvantage compared to the Company’s less leveraged competitors;

•increase the Company’s vulnerability to both general and industry-specific adverse economic conditions; and limit, among other things, the Company’s ability to borrow additional funds.

For example, due to the reduction in the Company’s earnings in the second half of 2003 and in 2004, the Company needed to seek an amendment from its senior lenders of the covenants in its senior credit agreement to provide greater flexibility. In exchange, the Company’s capital spending limits were reduced and the Company’s borrowing availability under its Senior Credit

17

Agreement was reduced. In addition, the Company obtained certain waivers during 2005 on the minimum net worth requirements under its Bonding Agreement. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

The financial covenants required by the Company’s Senior Credit Agreements and Bonding Agreement are restrictive. If there is a future violation of any of the financial covenants and the Company is not successful in obtaining additional amendments or waivers, a default would occur under the Company’s Senior Credit Agreements and Bonding Agreement, which would result in a material adverse impact on the Company’s financial condition.

If the Company is unable, in the future, to obtain bonding for its dredging contracts, the Company’s ability to obtain future dredging contracts would be limited, thereby adversely affecting the Company’s business.

The Company, like all dredging service providers, is generally required to post bonds in connection with its domestic dredging contracts to ensure job completion upon failure of the Company to finish a project. The Company has entered into a bonding agreement with Travelers Casualty and Surety Company of America, (“Travelers”) pursuant to which Travelers acts as surety, issues bid bonds, performance bonds and payment bonds, and obligates itself upon other contracts of guaranty required by the Company in the day-to-day operations of the Company’s dredging and marine construction business. However, Travelers is not obligated under the bonding agreement to issue bonds for the Company. Therefore, if the Company were unable to obtain additional bonds, its ability to take on future work would be severely limited.

The Company’s business is subject to significant operating risks and hazards that could result in damage or destruction to persons or property, which could result in losses or liabilities to the Company.

The businesses of dredging and demolition are generally subject to a number of risks and hazards, including environmental hazards, industrial accidents, encountering unusual or unexpected geological formations, cave-ins below water levels, collisions with fixed objects, disruption of transportation services and flooding. These risks could result in damage to, or destruction of, dredges, transportation vessels, other maritime structures and buildings, and could also result in personal injury, environmental damage, performance delays, monetary losses or legal liability.

The Company is subject to risks related to its international operations.

Approximately 13% of the Company’s dredging revenues for the year ended December 31, 2005 were generated by operations conducted abroad. International operations subject the Company to additional risks, including:

•uncertainties concerning import and export license requirements, tariffs and other trade barriers;

•restrictions on repatriating foreign profits back to the United States;

•changes in foreign policies and regulatory requirements;

•difficulties in staffing and managing international operations;

18

•taxation issues;

•currency fluctuations; and

•political, cultural and economic uncertainties.

The amount of the Company’s estimated backlog is subject to change and not necessarily indicative of future revenues.

The Company’s dredging contract backlog represents its estimate of the revenues that the Company will realize under contracts remaining to be performed based upon estimates relating to, among other things, the time required to mobilize the necessary assets at the project site, the amount of material to be dredged and the time necessary to demobilize the project assets. However, these estimates are necessarily subject to fluctuations based upon the amount of material that actually must be dredged, as well as factors affecting the time required to complete each job. Consequently, backlog is not necessarily indicative of future revenues or profitability. In addition, because a majority of the Company’s dredging backlog relates to government contracts, it can be canceled at any time without penalty, subject to the Company’s right, in some cases, to recover its actual committed costs and profit on work performed up to the date of cancellation.

The Company’s profitability is subject to inherent risks because of the fixed-price nature of most of its contracts.

Substantially all of the Company’s contracts with its customers are fixed-price contracts. Under a fixed-price contract, the customer agrees to pay a specified price for the Company’s performance of the entire contract. Fixed-price contracts carry inherent risks, including risks of losses from underestimating costs, operational difficulties and other changes that may occur over the contract period. One of the most significant factors affecting the profitability of a dredging project is the weather at the project site. Inclement or hazardous weather conditions can result in substantial delays in dredging and additional contract expenses. Due to these factors, it is possible that the Company will not be able to perform its obligations under fixed-price contracts without incurring additional expenses. If the Company were to significantly underestimate the cost of one or more significant contracts, the resulting losses could have a material adverse effect on the Company.

The Company’s business could suffer in the event of a work stoppage by the Company’s unionized labor force.

The Company is a party to numerous collective bargaining agreements in the U.S. that govern its relationships with its unionized hourly workforce. However, four primary agreements apply to approximately 84% of such employees. The inability to successfully renegotiate contracts with these unions as they expire, any future strikes, employee slowdowns or similar actions by one or more unions could have a material adverse effect on the Company’s ability to operate the Company’s business.

19

Environmental regulations could force the Company to incur significant capital and operational costs.

The Company’s operations and facilities are subject to various environmental laws and regulations relating to, among other things: dredging operations; the disposal of dredged material; protection of wetlands; storm water and waste water discharges; demolition activities; asbestos removal; transportation and disposal of other hazardous substances and materials; and air emissions. The Company is also subject to laws designed to protect certain marine species and habitats. Compliance with these statutes and regulations can delay performance of particular projects and increase related project costs. These delays and increased costs could have a material adverse effect on the Company’s results of operations.

The Company’s projects may involve demolition, excavation, transportation, management and disposal of hazardous waste and other hazardous substances and materials. Various laws strictly regulate the removal, treatment and transportation of hazardous waste and other hazardous substances and materials and impose liability for human health effects and environmental contamination caused by these materials. The Company’s demolition business, for example, requires the Company to transport and dispose of hazardous substances and materials, such as asbestos. The Company takes steps to limit the Company’s potential liability by hiring qualified asbestos abatement subcontractors to remove these materials from the Company’s projects, and some project contracts require the client to retain liability for hazardous waste generation. The failure of certain contractual protections, including any indemnification from the Company’s clients or subcontractors, to protect the Company from incurring such liability could have a material adverse effect on the Company’s business, financial condition or results of operations.

The Company’s demolition business depends on key customer relationships and reputation in the Boston contraction market developed and maintained by its key operations manager. Loss of any of these elements would materially reduce the Company’s demolition revenues and profits.

Demolition contracts are entered into on a project by project basis, so the Company does not have continuing contractual commitments with its demolition customers beyond the terms of the current contract. NASDI benefits from key relationships with certain general and construction contractors in the Boston market. NASDI also, benefits from its reputation in the Boston market developed over years of successfully performing on projects. Both of these aspects of the business were developed and are maintained through the demolition business’ key manager. The inability to maintain relationships with these customers or obtain new customers based on the Company’s reputation would reduce the revenue and profitability from demolition contracts. The inability of the Company to retain its key demolition manager would have a material adverse affect on the Company’s current customer relationships and reputation.

Item  2. – Properties

Dredging. Great Lakes’ dredging fleet is the largest in the U.S. and one of the largest fleets in the world. The fleet consists of over 200 pieces of equipment, including the largest hopper fleet and most of the large hydraulic dredges in the U.S., and is sufficient to meet the Company’s project requirements.

The following table provides a listing of the Company’s fleet of dredging equipment as of December 31, 2005, including equipment under long-term operating leases.

Type of Equipment	Quantity
Hydraulic Dredges	12
Hopper Dredges	8
Mechanical Dredges	6
Unloaders	2
Drillboats	2
Material Barges	24
Other Barges	62
Booster Pumps	7
Tugs	6
Launches and Survey Boats	52
Other ancillary equipment	30
Total	211

A significant portion of the Company’s operating equipment is subject to liens by the Company’s senior lenders and bonding company. See Note 6, “Property and Equipment,” and Note 12, “Long-term Debt,” in the Notes to the Consolidated Financial Statements.

The Company leases approximately 40,000 square feet of office facilities in Oak Brook, Illinois, which serves as its principal administrative facility. The primary lease for this property will expire in the year 2008. The Company also leases waterfront properties in Baltimore, Maryland, and Green Cove Springs, Florida. These locations serve as mooring sites for idle equipment and inventory storage.

Demolition. NASDI rents its primary office facility in Allston, Massachusetts, and a garage and maintenance facility in Everett, Massachusetts. NASDI maintains a fleet of operating equipment including excavators, loaders, trucks, and similar equipment, sufficient to meet its project requirements. Certain pieces of equipment are obtained under capital lease arrangements.

Item  3. – Legal Proceedings

Although the Company is subject to various claims and legal actions that arise in the ordinary course of business, except as described below, the Company is not currently a party to any material legal proceedings or environmental claims.

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

21

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. Management does not believe that these cases will have a material adverse impact on the 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 continues to comply 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.

In 1999, the Boston Housing Authority (“BHA”), for whom the Company’s demolition business, NASDI, had worked, asserted that NASDI and its subcontractors were responsible for improperly disposing of some contaminated materials. At the time the Company acquired NASDI in 2001, it was believed that NASDI had sufficient recourse in the matter and that any potential liability would be minimal. However, since 2001, certain of the insurance carriers that would be responsible for this matter have gone bankrupt. Negotiations between the parties have continued to progress, and in the third quarter of 2004, the case went before a judge in the Massachusetts court system who advised NASDI and the subcontractors to accept a settlement with the BHA. Therefore, in the third quarter of 2004, the Company recorded a $1.3 million charge for NASDI’s share of this potential settlement liability. This final settlement was paid in the fourth quarter of 2005. Company management believes there is no further liability to the Company related to this matter.

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.

On August 15, 2003 a claim was brought in the Landesgericht (District Court) of Berlin, Germany against Great Lakes by Hafemeister Erd-und Tiefbau GmbH, a German construction Company. On June 8, 2004 Great Lakes was served with notice of this claim, alleging that in

22

2000 the Company along with a Dutch company wrongfully withdrew from a consortium prior to the submission of a tender for a project to be performed in Germany. The claimant is seeking damages from its inability to bid on or perform the works in the amount of approximately €21,000. Great Lakes filed a petition with the German courts to seek dismissal of the claim for lack of factual and legal merit. A hearing occurred in December 2005 and the claim was dismissed. Although the claimant has the right to appeal the dismissal, Company management believes there will be no liability to the Company related to this matter.

Part II

Item  5. – Market for the Registrant’s Common Equity and Related Stockholder Matters

There is no established public market for the common stock of the Company. At December 31, 2005, GLDD Acquisitions Corp. owned 100% of the outstanding common stock of the Company. Madison Dearborn Capital Partners IV, L.P. and its co-investors own approximately 85% and certain members of the Company’s management own in aggregate approximately 15% of the outstanding common equity of GLDD Acquisitions Corp.

The ability of the Company to pay dividends is restricted by certain covenants contained in the Company’s Credit Agreement, as well as certain restrictions contained in the Company’s indenture relating to its subordinated debt.

Item  6. - Selected Financial Data

The following table sets forth certain financial data regarding the Company and should be read in conjunction with the consolidated financial statements and notes thereto (see Item 15, “Financial Statements” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”). The income statement and balance sheet data presented below have been derived from the Company’s consolidated financial statements. The acquisition of the Company by MDP in December 2003 was accounted for as a purchase in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 141, “Business Combinations,” resulting in a new basis of accounting subsequent to the transaction. Therefore, for presentation herein and throughout the remainder of this Report, financial information relating to the Company prior to the sale transaction is denoted as Predecessor Basis, while financial information relating to the Company subsequent to the transaction is denoted as Successor Basis.

EBITDA, as provided herein, represents net income (loss), adjusted for net interest expense, income taxes, depreciation and amortization expense. The Company presents EBITDA as an additional measure by which to evaluate the Company’s operating trends. The Company believes that EBITDA is a measure frequently used to evaluate performance of companies with substantial leverage and that all of its primary stakeholders (i.e. its bondholders, banks and investors) use EBITDA to evaluate the Company’s period to period performance. Additionally, management believes that EBITDA provides a transparent measure of the Company’s recurring operating performance and allows management to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance. For this reason, EBITDA is the measure the Company uses to assess performance for purposes of determining compensation under its incentive plan. EBITDA should not be considered an alternative to, or more meaningful than, amounts determined in accordance with GAAP including: (a) operating income as an indicator of operating performance; or (b) cash flows from operations as a measure of liquidity. As such, the Company’s use of EBITDA, instead of a GAAP measure, has limitations as an analytical tool, including the inability to determine profitability or liquidity due to the exclusion of interest expense and the associated significant cash requirements and the exclusion of depreciation and amortization, which represent significant and unavoidable operating costs given the level of indebtedness and capital expenditures needed to maintain the Company’s business. For these reasons, the Company uses operating income to measure its operating performance and uses EBITDA only as a supplement. EBITDA is reconciled to net income (loss) in the table of financial results.

Item 7. - Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

Great Lakes is the largest provider of dredging services in the United States. Dredging generally involves the enhancement or preservation of navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. The U.S. dredging market consists of three primary types of work: capital, beach nourishment and maintenance, in which sectors the Company has experienced an average combined bid market share in the U.S. of 36% over the past three years. The Company’s largest domestic dredging customer is the U.S. Army Corps of Engineers, which has responsibility for federally funded projects related to navigation and flood control. In 2005, approximately 79% of the Company’s dredging revenues were earned from contracts with federal government agencies, including the Corps as well as other

26

federal entities such as the U.S. Coast Guard and U.S. Navy. Given this dependence on federal revenues, the Company’s operations can be influenced by the federal budget and the amount appropriated and funded for dredging in any given year. Therefore, the Company tracks the annual appropriation process, to the extent that information is available, to assist it in planning for and managing its operations. The Company has also continued its role as the only U.S. dredging contractor with significant international operations, which represented an average of 16% of its dredging contract revenues over the past three years. The international operations provide additional customer diversification, which can be particularly beneficial if there is a downturn in the domestic economy.

The Company also owns 85% of the capital stock of North American Site Developers, Inc. (“NASDI”), a demolition service provider located in the Boston, Massachusetts area. NASDI’s principal services consist of interior and exterior demolition of commercial and industrial buildings, salvage and recycling of related materials, and removal of hazardous substances and materials. One NASDI management stockholder retains a 15% non-voting interest in NASDI, which is reflected as the minority interest in the Company’s consolidated financial statements. Since the acquisition of NASDI in 2001, the Company has operated in two reportable segments: dredging and demolition.

Contract Revenues

Most of the Company’s dredging contracts are obtained through competitive bidding on terms specified by the party inviting the bid. The nature of the specified services dictates the types of equipment, material and labor involved, all of which affect the cost of performing the contract and the price that dredging contractors will bid.

The Company recognizes contract revenues under the percentage-of-completion method, based on the Company’s engineering estimates of the physical percentage completed for dredging projects and using a cost-to-cost approach for demolition projects. For dredging projects, costs of contract revenues are adjusted to reflect the gross profit percentage expected to be achieved upon ultimate completion of each dredging project. For demolition projects, contract revenues are adjusted to reflect the estimated gross profit percentage. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Claims for additional compensation due the Company are not recognized in contract revenues until such claims are settled. Billings on contracts are generally submitted after verification with the customers of physical progress and may not match the timing of revenue recognition. The difference between amounts billed and recognized as revenue is reflected in the balance sheet as either contract revenues in excess of billings or billings in excess of contract revenues. Modifications may be negotiated when a change from the original contract specifications is encountered, necessitating a change in project scope or performance methodology and/or material disposal. Significant expenditures incurred incidental to major contracts are deferred and recognized as costs of contracts based on contract performance over the duration of the related project. These expenditures are reported as prepaid expenses.

27

Costs and Expenses

The components of costs of contract revenues include labor, equipment (including depreciation, insurance, fuel, maintenance and supplies), subcontracts, rentals, lease expense, and project overhead. The hourly labor is generally hired on a project basis and laid off upon the completion of the project. Costs of contract revenues vary significantly depending on the type and location of work performed and assets utilized. Generally, capital projects have the highest margins due to the complexity of the projects, while beach nourishment projects have the most volatile margins because they are most often exposed to weather conditions.

The Company’s cost structure includes significant annual fixed costs, including depreciation, maintenance, insurance and long-term equipment rentals, averaging approximately 22% to 25% of total costs of contract revenues. During the year, both equipment utilization and the timing of fixed cost expenditures fluctuate significantly. Accordingly, the Company allocates these fixed equipment costs to interim periods in proportion to revenues recognized over the year to better match revenues and expenses. Specifically, at each interim reporting date the Company compares actual revenues earned to date on its dredging contracts to expected annual fixed equipment costs. In the fourth quarter, any over and under allocated fixed equipment costs are recognized such that the expense for the year equals actual fixed equipment costs. As a result of this methodology, the recorded expense in any interim period may be higher or lower than the actual fixed equipment costs incurred.

Critical Accounting Policies and Estimates

The Company’s significant accounting policies are discussed in the notes to the financial statements. The application of certain of these policies requires significant judgments or an estimation process that can affect the results of operations, financial position and cash flows of the Company, as well as the related footnote disclosures. The Company bases its estimates on historical experience and other assumptions that it believes are reasonable. If actual amounts are ultimately different from previous estimates, the revisions are included in the Company’s results of operations for the period in which the actual amounts become known. The following accounting policies comprise those that management believes are the most critical to aid in fully understanding and evaluating the Company’s reported financial results.

Percentage-of-completion method of revenue recognition – The Company’s contract revenues are recognized under the percentage-of-completion method, which is by its nature based on an estimation process. For dredging projects, the Company uses engineering estimates of the physical percentage of completion. For demolition projects, the Company uses estimates of remaining costs-to-complete to determine project percent complete. In preparing its estimates, the Company draws on its extensive experience in the dredging and demolition businesses and its database of historical information to assure that its estimates are as accurate as possible, given current circumstances. Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Claims for additional compensation are not recognized in contract revenues until such claims are settled. It is reasonably possible that cost and profit estimates may be reviewed on a periodic basis to reflect changes in expected project performance.

28

Impairment of goodwill – Goodwill is assessed for impairment annually or more frequently if impairment indicators are identified. The assessment requires various assumptions regarding estimated future cash flows to determine the fair value of the reporting units to which the goodwill relates. If these estimates or their related assumptions change the fair value of the reporting units in the future, the Company may be required to record an impairment to goodwill.

Impairment of long-lived assets – In assessing the recoverability of the Company’s long-lived assets, primarily operating equipment and intangible assets other than goodwill, the Company makes assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets. As it relates to its operating equipment, the Company may estimate cash flows and make assumptions regarding useful lives based on internal historical operating data. If these estimates or their related assumptions change the fair value of these assets in the future, the Company may be required to record impairment charges.

Self-insurance reserves – The Company self-insures estimated costs associated with workers’ compensation claims, hull and equipment liability and general business liabilities, up to certain limits. Insurance reserves are established for estimates of the loss that the Company will ultimately incur on reported claims, as well as estimates of claims that have been incurred but not yet reported. In determining its estimates, the Company incorporates historical loss experience and judgments about the present and expected levels of cost per claim. Trends in actual experience are a significant factor in determination of such reserves.

Income taxes – The Company calculates its current and deferred tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed during the subsequent year. Adjustments based on filed returns are recorded when indentified, which is generally in the third quarter of the subsequent year for U.S. federal and state provisions. The amount of income taxes the Company pays is subject to ongoing audits by federal, state and foreign tax authorities, which may result in proposed assessments. The Company’s estimate for the potential outcome for any uncertain tax issue is highly judgmental. Management believes it has adequately provided for any reasonably foreseeable outcome related to these matters. However, the Company’s future results may include favorable or unfavorable adjustments to estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire.

The year ended December 31, 2005, while still challenging for the Company, was certainly an improved year. The year ended December 31, 2004 presented significant challenges to the industry including a significant reduction in work put out for bid (in the second half of 2003 and first half of 2004), postponement of projects already awarded and a general lack of certainty regarding funding. These difficulties were primarily attributed to the diversion of Corps personnel and financial resources to the reconstruction efforts in Iraq and the disruption in Corps’ districts ability to request and receive funding due to the Corps’ own internal administrative reorganization. In addition, the increasing federal deficit has only added to the funding constraints at the Corps. However, beginning in the second half of 2004 the bid activity accelerated and was solid throughout 2005. Unfortunately, while bidding activity has been robust over this period, pricing has not improved as competitors continued to bid aggressively to gain utilization. However, given the Company’s backlog levels during 2005, including a sizable portion of foreign work, the Company bid the available opportunities at more reasonable margins. This resulted in a decreased market share won by the Company in 2005 but, margins on work won were not as severely impacted as they were on work won in 2004. In addition, some of the work in the Company’s backlog that had been previously postponed by the Corps was executed in 2005. As a result, during 2005 fleet utilization improved significantly but margins were still not at the levels seen prior to 2004.

32

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

The Company’s revenues for 2005 were $423.4 million, representing an increase of $72.5 million, or 20.7%, compared to 2004 revenues of $350.9 million. The increase in revenues was driven by the increase in domestic dredging revenue resulting from performing certain capital projects in backlog that the Corps had postponed in 2004, coupled with the increase in bidding activity as discussed previously, as well as an increase in activity from the demolition business. The Company experienced improved equipment utilization and increased revenue throughout the year.

The Company’s 2005 gross profit margin was 12.1%, which improved from the 2004 level of 10.2%. The improvement in 2005’s gross profit margin was primarily attributable to the mix of projects performed during the year, including more capital work with improved margins and the decreased impact of fixed costs relative to the increased level of utilization for the year.

Dredging revenues were $374.3 million in 2005, an increase of $60.5 million over 2004 revenue. Detail of the revenue increase is below. Dredging gross profit was 11.6% in 2005 compared to 9.4% in 2004. Again, this is due to increased fleet utilization throughout the year as more work in backlog was performed and the bid market continued to strengthen.

•Domestic capital dredging revenues increased $19.5 million, or 13.7%, to $161.2 million in 2005 from $141.7 million in 2004. As mentioned above, the increase resulted in part from the Corps’ funding capital projects that were in the Company’s backlog but had been previously postponed, including work at the Company’s projects in Brunswick, GA and Wilmington, NC. The Company also performed work on capital projects in Miami, FL, Arthur Kill, NY and Oakland, CA.

•The Company’s 2005 revenues from beach nourishment projects of $92.8 million were significantly greater than the 2004 level of $51.3 million. The 2005 beach bid market was $297 million, well in excess of the prior five year historical annual average of approximately $114 million. Much of the 2005 beach work was funded by an emergency supplemental bill passed in 2004 to pay for damage from the severe hurricane season experienced in 2004, particularly along the coasts of Florida.

•Revenues from maintenance projects in 2005 increased $15 million, or 26.9%, to $73.0 million compared to $58.0 million in 2004. The 2005 maintenance market was on par with the prior five year historical annual average markets. The Company’s portion of revenues generated from maintenance work fluctuates depending on the Company’s availability of equipment for such work.

•Revenues from foreign dredging operations in 2005 totaled $47.4 million, which is down $15.5 million, or 24.6% from 2004 revenues of $62.9 million, as the Company completed one large project in Bahrain and began mobilized onto a second sizable job in the same country.

NASDI’s 2005 demolition revenues of $49.1 million, increased $12.0 million, or 32.3%, over 2004 revenues of $37.1 million. The demolition sector had solid activity in 2005 with an

33

increase in both the number of projects and the number of larger projects (in the range of $1 to $5 million). The gross profit margin attributable to NASDI’s demolition business stayed relatively consistent at 16.4% compared to 16.8% in  2004.

For the year ended December 31, 2005, general and administrative expenses totaled $38.7 million, compared to $33.5 million in 2004. 2005 includes the impact of a non-cash write-down of goodwill and intangible assets of $5.7 million, related to the Company’s demolition segment. Although NASDI has shown improvement in earnings during 2005 and is expected to continue to achieve positive cash flows in the future, Company management does not believe it will meet the future returns contemplated when the goodwill was originally allocated through purchase accounting in 2003. These downward revised projections for the demolition business are attributable to higher anticipated incentive compensation required to retain its key manager. Included in both years’ expense is amortization of intangibles, which decreased in 2005 to $0.8 million from $4.2 million in 2004 due to the relatively short term nature of the most significant intangibles, recorded in purchase accounting in 2003. In addition, both 2005 and 2004 include significant expense of $2.9 and $2.3 million respectively, for legal fees and other costs related to the provision of documents in response to the Department of Justice’s subpoena. 2004 expense also includes $1.3 million for the settlement cost of litigation related to NASDI as further described in Item 3, “Legal Proceedings.”  Therefore, excluding the incremental costs in each year, the Company’s 2005 general and administrative expenses would have been approximately $3.9 million greater, primarily as a result of increased incentive compensation, driven by the improvement in the Company’s dredging segment, along with the additional incentive compensation recorded by the Company’s demolition segment.

Operating income for the dredging segment was $15.2 million, up $13.7 over 2004 operating income of $1.5. This is due to the increased revenue in 2005 as well as the increased utilization throughout the year. Demolition operating loss was $2.5 million in 2005 compared to operating income of $0.9 million in 2004. Although NASDI had a strong year and significantly increased revenue, the impairment of goodwill and intangibles write down of $5.7 million discussed above negatively impacted operating income.

The Company’s net interest expense for the year ended December 31, 2005 totaled $23.1 million compared to $20.3 million in 2004. The increase was due to the higher underlying interest rates and larger spreads on the Company’s variable rate debt.

As a result of its 2005 net operating loss, the Company generated an income tax benefit of $1.3 million. In 2004, the resulting income tax benefit was $4.4 million.

For the year ended December 31, 2005, the Company incurred a net loss of $6.9 million compared to a net loss of $11.1 million for the year ended December 31, 2004. The 2005 net loss, which includes the $5.7 million non-cash write-down of goodwill and intangible assets, is improved over the 2004 net loss primarily due to the increased utilization and gross margins as described above.

Year Ended December 31, 2004 Compared to Year Ended December 31, 2003

The Company’s revenues for 2004 were $350.9 million, representing a decline of $47.9 million, or 12.0%, compared to 2003 revenues of $398.8 million. The decline in revenues was driven by

34

the reduction in domestic capital dredging revenue resulting from the Corps’ postponement of certain capital project work within the Company’s backlog, coupled with the reduction in bidding activity as discussed above. This impact was particularly evident in the second and third quarters of 2004, when the Company was unable to perform on certain projects in backlog due to the Corps’ funding constraints and was unable to take on sufficient new work to mitigate the situation due to the contraction in the domestic bid market and the intense competition for bids therein. Therefore, the Company experienced a drop in equipment utilization and revenue in these quarters, particularly with respect to its hopper dredge operations.

The Company’s 2004 gross profit margin was 10.2%, which declined from the 2003 level of 17.7%. The decline in 2004’s gross profit margin was attributable to a number of factors, including: 1) the mix of projects performed during the year, some of which were at inherently lower margins given the competitive environment in which they were bid and some of which were negatively impacted by the hurricanes experienced primarily in the third quarter, 2) the impact of fixed costs relative to the reduced level of utilization for the year, and 3) approximately $6.0 million (or approximately 2% of 2004 revenues) of incremental depreciation expense resulting from the revaluation of the Company’s operating assets in connection with the sale of the Company in December of 2003.

Dredging revenues in 2003 were $313.8, down $47.1 million from 2002. Detail on the dredging revenue decrease is below. Dredging gross profit was 9.4% in 2004 compared with 18.3% in 2003. This decrease in margin was due to the factors noted above, including primarily lower margin work being performed and decreased utilization.

•Domestic capital dredging project revenues decreased $62.0 million, or 30.4%, to $141.7 million in 2004 from $203.7 million in 2003. As mentioned above, the decrease resulted in part from the Corps’ postponement of capital project work within the Company’s backlog. A portion of the work on the Company’s Brunswick and Wilmington Deep Port projects was deferred until the Corps has remaining funds available; therefore, the Company was unable to perform as much of this work in 2004 as originally anticipated. Work did commence on Brunswick in 2006 and Wilmington in 2005. Additionally, because very little capital work was bid in the second half of 2003 or first half of 2004, the Company did not take on new capital work which could be performed during the earlier part of 2004. As bid activity and funding increased in the second half of 2004, the Company was able to perform more domestic capital project work. Therefore, the Company’s capital dredging revenues in the fourth quarter of 2004 actually exceeded the capital revenues in the same period of 2003, but this did not make up for the significant decline through the first nine months of 2004 resulting from the work deferrals and lack of new work.

•The Company’s 2004 revenues from beach nourishment projects of $51.3 million were relatively consistent with the 2003 level of $47.9 million. The 2004 beach bid market remained strong at approximately $110 million; however, the majority of the Company’s 2004 beach revenues were generated by projects in the Company’s backlog at the end of 2003.

•Revenues from maintenance projects in 2004 increased $9.6 million, or 19.9%, to $58.0 million compared to $48.4 million in 2003. The annual maintenance dredging volume can

35

vary depending on levels of Midwest precipitation experienced during the winter months, and the active hurricane season in 2004 may have created additional shoaling as well, since the 2004 annual market was somewhat larger than in recent years.

•Revenues from foreign dredging operations in 2004 totaled $62.8 million, which is consistent with 2003 revenues of $60.9 million, as the Company incurred similar levels of utilization for its foreign-based fleet.

NASDI’s 2004 demolition revenues totaled $37.1 million, which was consistent with its 2003 revenues of $38.0 million. The gross profit margin attributable to NASDI’s demolition business improved in 2004 to 16.8%, from 13.0% in 2003, due to the mix of projects performed and the benefit of salvage revenue realized on one of NASDI’s large infrastructure take-downs.

For the year ended December 31, 2004, general and administrative expenses totaled $33.5 million, compared to $27.9 million in 2003 (excluding $10.6 million of nonrecurring sale-related expenses). The 2004 expenses include approximately $2.3 million of incremental legal and other costs related to the provision of documents in response to the Department of Justice’s subpoena and $1.3 million for the anticipated settlement cost of ongoing litigation against NASDI, as further described in Item 3, “Legal Proceedings.”  Additionally, in 2004, the Company incurred non-cash amortization of $4.2 million relating to intangible assets established in purchase accounting with respect to the Company’s sale in December 2003. If not for these incremental costs, the Company’s savings in 2004 general and administrative expenses relative to 2003 would have been approximately $2.2 million, relating primarily to reductions in incentive pay and profit sharing expenses due to the Company’s reduced level of earnings in 2004.

Operating income for the dredging segment was $1.5 million, down over 2003 operating income of $29.7 million. This is due to the decreased revenue in 2004 and the resulting decrease in utilization throughout the year. Demolition operating income was $0.9 million in 2004 down from 2.5 million in 2003. Although NASDI had a strong year and an increase in gross profit, the $1.3 million charge for ongoing litigation resulted in the decrease in operating income year over year.

The Company’s net interest expense for the year ended December 31, 2004 totaled $20.3 million compared to $20.7 million in 2003. In connection with the sale of the Company in December 2003, the Company’s debt level increased to approximately $260 million at the beginning of 2004, compared to outstanding debt of approximately $160 million prior to the sale. However, despite the increase in debt, cash interest expense has remained comparable due to the significantly lower interest rates on the new debt structure. In 2003, the Company incurred additional financing costs of $13.1 million related to the early extinguishment of its former debt, including call and tender premiums to retire the old notes and the write-off of deferred financing costs related to its former debt.

As a result of its 2004 net operating loss, the Company generated an income tax benefit of $4.4 million. In 2003, as a result of the significant tax deductions for the sale-related expenses, the Company had a loss for federal tax purposes that was carried back to earlier years resulting in no 2003 federal provision; therefore, the 2003 income tax expense of $1.3 million related primarily to current state and foreign taxes.

36

For the year ended December 31, 2004, the Company incurred a net loss of $11.1 million compared to a net loss of $1.6 million for the year ended December 31, 2003. The 2004 net loss reflects the impact of incremental depreciation and amortization expense of approximately $10.0 million resulting from the revaluation of the Company’s assets and liabilities in connection with the sale of the Company in December 2003, as well as the impact of reduced margins and additional general and administrative expenses, as discussed previously. The 2003 net loss was a result of the nonrecurring sale-related expenses mentioned previously.

Bidding Activity and Backlog

The Company’s contract backlog represents management’s estimate of the revenues that will be realized under the portion of the contracts remaining to be performed. Such estimates are subject to fluctuations based upon the amount of material actually dredged as well as factors affecting the time required to complete the job. In addition, because a substantial portion of the Company’s backlog relates to government contracts, the Company’s backlog can be canceled at any time without penalty; however, the Company can generally recover the actual committed costs and profit on work performed up to the date of cancellation. Consequently, backlog is not necessarily indicative of future results. The Company’s backlog includes only those projects for which the customer has provided an executed contract.

Dredging. The 2005 bid market of $727 million was similar to the 2004 bid market of $739 million. Both years were a solid improvement over the 2003 bid market, which was lower than typical at only $425 million and both years were slightly above the five-year average of $690 million. The Company was the successful bidder on projects valued at approximately $225 million, representing 31% of the domestic bid market, as compared to its historical market share of 40%. Throughout 2005, even with the increased activity in the bid market, others in the dredging industry continued to bid very aggressively to gain utilization. However, as the Company chose to bid opportunities at more reasonable margins, its market share declined.

The Company’s dredging backlog at December 31, 2005 totaled $260.8 million, which compares to $266.1 million at September 30, 2005 and $279.7 million at December 31, 2004.

Approximately 36% of the Company’s year-end dredging backlog, or $94.5 million, consists of Deep Port or other domestic capital dredging work, which will be substantially performed in 2006. Only one Deep Port project in New York was awarded in 2005 with a total value of $79 million which was won by a competitor. The 2005 market also included other capital projects not funded by the Deep Port program valued at approximately $121 million and the Company won 45%, or $54 million, of this work.

The Water Resources Development Act, or WRDA legislation, which includes  authorization of the Corps’ civil works projects, was again not passed in 2005 as various other issues took precedent, not the least of which was a large authorization bill for transportation. The transportation bill was passed in 2005 and now the feeling is that the water bill should be next and that it is a high priority for passage early in 2006. Positives for the industry included in the current WRDA are the retirement of the Corps’ Dredge McFarland which should add work for industry, the reduction in local cost sharing required on projects that go below 50 feet and authorization for 12 priority projects under the Louisiana Coastal Restoration Plan, as well as the

37

authorization of various additional harbor deepening projects. Passage of this bill will give assurance of continuing commitment to capital dredging work out in the future.

Foreign capital backlog increased to $90.0 million at the end of 2005 compared to $42.6 million at the end of 2004 due to the addition during the year of a large land reclamation project currently being performed in Bahrain.

The 2005 beach nourishment bid market totaled $297 million, which is well above the average bid market over the last five years of $154 million. The Company won $135 million, or 45%, of this work, bringing the Company’s beach backlog to $61.4 million at December 31, 2005. Although greater than 2004, this was lower than the Company’s five-year historical average market share of 50% for beach work, given the extremely competitive pricing of the projects bid in 2004 and 2005. While the 2005 beach nourishment market has clearly benefited from the supplemental federal funding passed in 2004, there continues to be uncertainty regarding funding for beach nourishment work going forward, as the current administration does not support federal funding for this work. Near term schedules indicate beach nourishment projects valued at approximately $120 million for bidding through mid-2006. A number of these projects are sponsored by localities in Florida that have secured the funding for their projects through bond issues and taxes, recognizing the cost/benefit to performing this work. As more municipalities devise a means to fund their individual projects, this will help to sustain the beach nourishment market even if the federal government reduces its commitment to this work.

The 2005 maintenance bid market totaled $230 million, which is on par with the average maintenance market over the last five years of $249 million. The Company’s share of the 2005 market was 16%, again lower than its historical average of 26%, due to the competitive environment experienced in 2005.

At December 31, 2005, the Company had dredging work pending award valued at $29.8 million. This included low bids for an $11.9 million beach nourishment project in Masonboro North Carolina, as well as options related to projects currently in backlog at year-end. The revenue value of these low bids and options pending award will be reflected in the Company’s backlog upon execution of signed agreements for the work.

Demolition. The Company’s demolition backlog at December 31, 2005 totaled $17.4 million, which compares to $11.4 million at December 31, 2004. The 2005 year-end backlog includes three new projects each valued in excess of $1 million and a typical complement of mid-size projects. With an improved economy in the New England area and NASDI’s limited expansion into the Florida market, NASDI anticipates opportunities to bid on number of larger projects over the next year, increasing the potential for improved volume and margins in this segment.

Changes in Financial Condition

As discussed in the notes to the consolidated financial statements, the Company accounted for the acquisition by GLDD Acquisitions Corp. as a purchase, in accordance with SFAS No. 141, “Business Combinations.”  This resulted in a new basis of accounting, effective December 31, 2003, at which point the Company reflected its assets and liabilities at fair value. The excess of the purchase price paid over the net assets acquired was allocated primarily to property and equipment and other intangible assets, and deferred taxes related thereto, with the remaining

38

excess recorded as goodwill.  In 2005, the Company performed its annual assessment for the impairment of goodwill and intangibles.  As previously noted, a $5.7 non-cash write down was recorded related to the goodwill and intangibles in the demolition business that had been established as a result of the 2003 purchase price allocation.

Liquidity and Capital Resources

Historical

The Company’s principal sources of liquidity are cash flow generated from operations and borrowings under its senior credit facility (see Note 12, “Long-term Debt” in the Notes to the Consolidated Financial Statements).  The Company’s principal uses of cash are to meet debt service requirements, finance its capital expenditures, provide working capital and meet other general corporate purposes.

The Company’s net cash flows provided by operating activities for the years ended December 31, 2005 and 2004 (Successor Basis) and year ended December 31, 2003 (Predecessor Basis)  totaled $10.3 million, $17.5 million and $26.2 million, respectively.  The fluctuation in the Company’s operating cash flows was primarily due to the normal timing differences on the recognition and billing of revenues, relative to the current level of activity.  In 2005 and 2004, the Company also received distributions from its equity joint ventures totaling $1.6 million and $1.9 million, respectively. In 2004, the Company’s cash flows from operations benefited from the receipt of income tax refunds.

The Company’s net cash flows used in investing activities for the years ended December 31, 2005 and 2004 (Successor Basis) and year ended December 31, 2003 (Predecessor Basis) were $7.2 million, $11.4 million and $34.2 million, respectively.  The use of cash relates primarily to equipment acquisitions, offset by proceeds on the sale of equipment.  In 2005, the Company incurred capital expenditures of $12.7 million.  This was offset by proceeds of $5.5 million, of which $4.4 million was for a rock barge that was constructed in 2005 and then sold and leased back under an operating lease.  No gain was recognized on this transaction.  In 2004, the Company incurred capital expenditures of $23.1 million.  This was offset by proceeds of $10.3 million, which included $4.6 million for a rock barge that was constructed in 2004 and then sold and leased back under an operating lease, $4.7 million for capital improvements on the Company’s mechanical dredges that were reimbursed and financed by the lessor, and proceeds for other miscellaneous equipment disposals. In 2003, the Company incurred capital expenditures of $37.7 million, which included $15.3 million used to purchase two dredging vessels and certain ancillary equipment that were previously under an operating lease, as well as $3.6 million spent on construction of a barge, which was funded through a like-kind exchange transaction in connection with the sale of two tugboats in 2003, for which the Company received proceeds of $5.2 million.  A gain of $2.2 million was recognized on this transaction.  In 2003, the Company also utilized $1.0 million to purchase 50% of a real estate interest related to its Amboy joint venture and received $1.2 million related to the sale of its investment in Riovia S.A., a joint venture formed to perform a dredging project in Argentina.

The Company’s net cash flows used in financing activities for the years ended December 31, 2005 and 2004 (Successor Basis) were $4.5 million and $6.8 million respectively, primarily related to scheduled payments under the Company’s senior Equipment Term Loan and voluntary

39

prepayments made under the Company’s senior bank facility Term Loan B of $3.5 million and $2.5 million, respectively.  In 2004, the Company also incurred financing fees of $1.1 million to obtain an amendment to its Credit Agreement and Equipment Term Loan (collectively, “Senior Credit Agreements”), as discussed below.  For the year ended December 31, 2003 (Predecessor Basis), the Company generated net cash flows from financing activities of $14.1 million, reflecting new borrowings of  $23.4 million under the Equipment Term Loan, which was used to refinance borrowings incurred under the former revolving credit facility, including $15.0 million in borrowings that were used to purchase certain dredging equipment which had previously been under operating lease, as mentioned above, offset by payments under its former term senior debt.

For the year ended December 31, 2003, the Company’s Successor Basis net cash flows reflected the impact of the sale of the Company in December 2003.  The Company’s net cash flow used in operations totaled $6.5 million for the payment of accrued interest on the Company’s former debt.  Successor Basis net cash flows used in investing activities were $149.1 million, reflecting the consideration paid to the Company’s former equity holders and related expenses in connection with the sale.  Successor Basis net cash flows from financing activities totaled $150.8 million which represented payments to extinguish the Company’s former debt, offset by proceeds from the issuance of new equity and new senior subordinated notes and bank debt also in connection with the sale.

Prospective

The Company’s Credit Agreement contains various restrictive covenants. It prohibits the Company from prepaying other indebtedness, including the senior subordinated notes, and it requires the Company to satisfy financial condition tests and to maintain specified financial ratios, such as a maximum total leverage ratio, maximum senior leverage ratio, minimum interest coverage ratio and maximum capital expenditures.  It also prohibits the Company from declaring or paying any dividends and from making any payments with respect to the senior subordinated notes if it fails to perform its obligations under, or fails to meet the conditions of, the Credit Agreement or if payment creates a default under the Credit Agreement.  The Company’s bonding agreement and Equipment Term Loan contain similar restrictive covenants and financial condition tests.

Due to the reduction in the Company’s earnings, the Company sought an amendment from its senior lenders of the covenants in its Senior Credit Agreements to provide greater flexibility to work through this challenging period.  These agreements were amended effective September 30, 2004 to allow additional flexibility in the Company’s leverage and interest coverage ratios, including replacement of the total leverage ratio with a required minimum EBITDA, as defined in the Senior Credit Agreements, through 2005.  In exchange, the Company’s capital spending limits were reduced and the Company’s borrowing availability under its Credit Agreement was reduced to $45 million (with a sub-limit of $35 million for letters of credit and $15 million for revolver borrowings), until such time that the Company achieves certain defined financial measures.  The Company’s bonding agreement was also amended to revise the minimum net worth requirements.

The Company’s Credit Agreement and Equipment Term Loan (collectively, “senior credit agreements”) and its Underwriting and Indemnity Agreement (“bonding agreement”) with its

40

surety provider contain certain provisions that require the Company to maintain a minimum net worth and certain other financial ratios, limit payment of dividends and restrict certain other transactions.  In response to the Company’s reduced earnings through the first half of 2005, the Company obtained an amendment to its credit agreement to provide additional liquidity to address certain near-term working capital needs in June of 2005.  The amendment increased the Company’s revolver borrowing availability by $5.0 million, with an offsetting decrease to the Company’s letter of credit capacity in the same amount for a defined period of time.  The Company did not utilize the additional revolver borrowing capacity, which reverted back to the pre-amendment level of $15.0 million on October 31, 2005.  The Company was in compliance with all of the financial covenants as revised under its senior credit agreements and bonding agreement at December 31, 2005.  Effective February 1, 2006, the Company’s borrowing availability reverted back to the full $60 million allowed under the original terms of its credit agreement with its senior lenders, based on the attainment of the certain defined financial measures in accordance with the terms of the September 2005 amendment to such credit agreement.  Additionally, on March 22, 2006 the Company amended its Credit Agreement to increase its sub-limit for letters of credit to $45 million, from $35 million.

The required financial covenant levels under the senior credit agreements and the bonding agreement are restrictive in light of the Company’s current level of earnings, but Company management believes the Company has positive relationships with the its senior lenders and surety provider, should it be necessary to request an additional amendment or waiver to the financial covenants.  However, if there is a future violation of any of the financial covenants and the Company is not successful in obtaining an additional amendment or waiver, a default could occur under the Company’s senior credit agreements or bonding agreement, which could result in a material adverse impact on the Company’s financial condition.

The Company has continued to experience some timing issues on certain Corps receivables, but Company management believes its anticipated cash flows from operations and current available credit under its revolving credit facility will be sufficient to fund the Company’s operations and its revised capital expenditures, and meet its current annual debt service requirements of approximately $22 million for the remainder of the year.  The Company’s ability to fund its working capital needs, planned capital expenditures and scheduled debt payments, and to comply with all of the financial covenants under its senior credit agreements and bonding agreement, depends on its future operating performance and cash flow, which in turn, are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond the Company’s control.

In February 2004, the Company entered into an interest rate swap arrangement to swap a notional amount of $50 million from a fixed rate of 7.75% to a floating LIBOR-based rate in order to manage the interest rate paid with respect to the Company’s senior subordinated notes.  At December 31, 2005 and 2004, the fair value accounting for the swap resulted in $1.6 million and $0.7 million of an additional non-cash charge to interest expense, respectively.   This represents the current fair value of the swap arrangement based on the anticipated future rates.  The Company made payments of approximately $0.2 million in 2005 on this swap arrangement and received payments of $0.5 in 2004.  The swap is not accounted for as a hedge, so the fair value is recorded directly to interest expense, thereby introducing potential income volatility on a quarter-by-quarter basis.

41

The Company has entered into operating lease agreements for certain dredging assets and office space, which require annual operating lease payments declining from $14 million to $8 million over the next five years.  See Note 15, “Lease Commitments” in the Notes to the Consolidated Financial Statements.  Additionally, the Company expects to incur annual maintenance expenses of approximately $28 million.  Amounts expended for operating leases and maintenance expenses are charged to operations on an annual basis. Planned capital expenditures, which primarily include support equipment and equipment upgrades, are expected to require spending of approximately $13 million to $18 million annually, to the extent permitted by the Company’s revised Senior Credit Agreements.

Management believes that cash flows from operations combined with the reinstated availability under the revolver (which is part of the Credit Agreement mentioned above) will be sufficient to fund the Company’s operations, debt service and capital expenditures for the next year.  The Company’s ability to fund its working capital needs, planned capital expenditures and scheduled debt payments, and to comply with all of the financial covenants under its debt agreements, depends on its future operating performance and cash flow, which in turn, are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond the Company’s control.

Contractual Obligations

The following table summarizes the Company’s contractual cash obligations at December 31, 2005.  Additional information related to these obligations can be found in Notes 12 and 15 to the Consolidated Financial Statements.

	Obligations coming due in year(s) ending:
					2007-		2010-		2013 and

(2)  Includes cash interest payments calculated at stated fixed rate of 7.75%.

Other Off-Balance Sheet and Contingent Obligations

The Company had outstanding letters of credit relating to foreign contract performance guarantees and insurance payment liabilities totaling $20.1 million at December 31, 2005.  All were undrawn at year-end.

42

The Company has granted liens on certain of its operating equipment with net book values at December 31, 2005 of $80.3 million, as security for borrowings under its Credit Agreement.  The Company’s Credit Agreement also contains provisions that require the Company to maintain certain financial ratios and restrict its ability to pay dividends, incur indebtedness, create liens, and take certain other actions.

The Company finances certain key vessels used in its operations with off-balance sheet lease arrangements with unrelated lessors, requiring annual rentals of $14 million to $8 million over the next five years.  These off-balance sheet leases contain default provisions, which are triggered by an acceleration of debt maturity under the terms of the Company’s Credit Agreement. Additionally, the leases typically contain provisions whereby the Company indemnifies the lessors for the tax treatment attributable to such leases based on the tax rules in place at lease inception.  The tax indemnifications do not have a contractual dollar limit.  To date, no lessors have asserted any claims against the Company under these tax indemnification provisions.

Performance and bid bonds are customarily required for dredging and marine construction projects, as well as some demolition projects.  The Company obtains its performance and bid bonds through a bonding agreement with Travelers, which has been granted a security interest in a substantial portion of the Company’s operating equipment with a net book value of approximately $83.5 million at December 31, 2005. The bonding agreement also contains provisions that require the Company to maintain certain financial ratios and restrict its ability to pay dividends, incur indebtedness, create liens, and take certain other actions.  Bid bonds are generally obtained for a percentage of bid value and amounts outstanding typically range from $5 to $10 million. At December 31, 2005, the Company had outstanding performance bonds valued at approximately $330 million; however, the revenue value remaining in backlog related to these projects totaled approximately $155 million.

Certain foreign projects performed by the Company have warranty periods, typically spanning no more than three to five years beyond project completion, whereby the Company retains responsibility to maintain the project site to certain specifications during the warranty period.  Generally, any potential liability of the Company is mitigated by insurance, shared responsibilities with consortium partners, and/or recourse to owner-provided specifications.

The Company considers it unlikely that it would have to perform under any of these aforementioned contingent obligations and performance has never been required in any of these circumstances in the past.

Item  7A. – Quantitative and Qualitative Disclosures about Market Risk

A portion of the Company’s current dredging operations are conducted outside of the U.S.  In 2005 and 2004, 13% and 20%, respectively, of dredging contract revenues were attributable to overseas operations.  It is the Company’s policy to hedge foreign currency exchange risk on contracts denominated in currencies other than the U.S. dollar, if available.  Forward currency exchange contracts, typically with durations of less than one year, are used to minimize the impact of foreign currency fluctuations on operations. The Company does not purchase forward exchange contracts for trading purposes and had no foreign currency forward contracts outstanding at December 31, 2005 or 2004.

The Company’s obligations under its Senior Credit Agreements expose its earnings to changes in short-term interest rates since interest rates on this debt are variable.  If the variable interest rates on the Company’s outstanding debt were to increase in 2006 by 10% from the rates at December 31, 2005, assuming scheduled principal payments are made, interest expense would increase by $0.6 million compared to $0.5 million for 2005, measured as of December 31, 2004.

At December 31, 2005 and 2004, the Company had long-term senior subordinated notes outstanding with a recorded book value of $175.0 million.   The fair value of these notes, which bear interest at a fixed rate of 7.75%, was $157.5 million and $157.9 million at December 31, 2005 and 2004, respectively, based on quoted market prices.  Assuming a 10% decrease in interest rates from the rates at December 31, 2005 and 2004, the fair value of this fixed rate debt would have increased to $167.1 million and $167.5 million, respectively.

In February 2004, the Company entered into an interest rate swap arrangement to swap a notional amount of $50.0 million from a fixed rate of 7.75% to a floating LIBOR-based rate in order to manage the interest rate paid with respect to the Company’s 7.75% senior subordinated notes.  The fair value of the swap at December 31, 2005 and 2004 was $(1.6) million and $(0.7) million, respectively.  Assuming a 10% increase in interest rates at December 31, 2005, the fair value of the swap would decline to $(2.3) million.

A significant operating cost for the Company is diesel fuel, which represents approximately 9.1% of the Company’s costs of contract revenues.  The Company uses fuel commodity forward contracts, typically with durations of less than two years, to reduce the impacts of changing fuel prices on operations.  The Company does not purchase fuel hedges for trading purposes.  Based on the Company’s 2006 projected domestic fuel consumption, a ten cent increase in the average price per gallon of fuel would increase its fuel expense by approximately $0.8 million, after the effect of fuel commodity contracts in place as of December 31, 2005, compared to an estimated $0.9 million for 2005 measured as of December 31, 2004.  If the fuel forward rates underlying the outstanding fuel contracts increased by 10%, the fair value of these contracts would increase by $0.7 million at December 31, 2005 and 2004, respectively.  At December 31, 2005 and 2004, the Company had outstanding arrangements to hedge the price of a portion of its fuel purchases related to domestic dredging work in backlog, representing approximately 24% and 76% of its anticipated domestic fuel requirements for 2006 and 2005, respectively.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of

Great Lakes Dredge & Dock Corporation

Oak Brook, Illinois

We have audited the accompanying consolidated balance sheets of Great Lakes Dredge & Dock Corporation and Subsidiaries (the “Company”) as of December 31, 2005 and 2004 (successor), and the related consolidated statements of operations, stockholder’s equity, and cash flows for the years then ended.  Additionally, we have audited the consolidated statement of operations, stockholder’s equity, and cash flows for the year ended December 31, 2003 (predecessor).  Our responsibility is to express an opinion on these financial statements based on our audits.  We did not audit the financial statements of Amboy Aggregates (“Amboy”) joint venture for the year ended December 31, 2003, the Company’s investment in which is accounted for using the equity method.  The Company’s equity of $1.0 million in Amboy’s net income for the year ended December 31, 2003, are included in the accompanying financial statements.  The financial statements of Amboy were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for such joint venture, is based solely on the report of such other auditors for the year ended December 31, 2003.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.  Our audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.  Accordingly, we express no such opinion.  An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 1 to the financial statements, the capital stock of the Company was acquired by GLDD Acquisitions Corp. in a business combination accounted for as a purchase.  The financial statements reflect the revaluation of the net assets of the Company at the date of acquisition.  Therefore, the amounts reported on the successor basis are not comparable to the amounts shown on the predecessor basis.

GREAT LAKES DREDGE & DOCK CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 (in thousands, except share and per share amounts)

1.Nature of business and summary of significant accounting policies

Organization and recapitalization

Great Lakes Dredge & Dock Corporation and its subsidiaries (the Company or Great Lakes) are in the business of marine construction, primarily dredging, and commercial and industrial demolition services. The Company’s primary dredging customers are domestic and foreign government agencies, and its primary demolition customers are general contractors, corporations that commission projects, non-profit institutions such as universities and hospitals, and local government and municipal agencies.

On December 22, 2003, Madison Dearborn Capital Partners IV, L.P. (MDP), an affiliate of Chicago-based private equity investment firm Madison Dearborn Partners, LLC, acquired control of Great Lakes from its former owner, Vectura Holding Company LLC (Vectura), for approximately $362 million, including fees and expenses, in a transaction accounted for as a purchase (the Transaction). The acquisition was effected by a new company established for this purpose, GLDD Acquisitions Corp., which now owns 100% of the equity securities of Great Lakes Dredge & Dock Corporation.  Certain members of Great Lakes’ management own approximately 15% of the outstanding common stock of GLDD Acquisitions Corp. and MDP and certain of its co-investors own the remaining 85%.  See Note 2 for a description of the Transaction.

Principles of consolidation and basis of presentation

The consolidated financial statements include the accounts of Great Lakes Dredge & Dock Corporation and its majority-owned subsidiaries. All significant intercompany accounts and transactions are eliminated.  The equity method of accounting is used for investments in unconsolidated investees in which the Company has significant influence.   Other investments, if any, are carried at cost.

The acquisition of the Company by MDP was accounted for as a purchase in accordance with Statement of Financial Accounting Standards (SFAS) No. 141, “Business Combinations,” resulting in a new basis of accounting subsequent to the Transaction.  For presentation herein, the financial statements up to the date of the sale are denoted as Predecessor Basis, while the financial statements prepared subsequent to the Transaction are denoted as Successor Basis.  The sale was accounted for as if it had occurred on

66

December 31, 2003.  Management determined that results of operations were not significant and no material transactions occurred during the period from December 23 to December 31, 2003.

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 that affect certain reported amounts and disclosures.  Accordingly, actual results could differ from those estimates.

Revenue and cost recognition on contracts

Substantially all of the Company’s contracts for dredging services are fixed-price contracts, which provide for remeasurement based on actual quantities dredged.  The majority of the Company’s demolition contracts are also fixed-price contracts, with others managed as time-and-materials or rental projects.  In accordance with the American Institute of Certified Public Accountants’ Statement of Position 81-1, “Accounting for the Performance of Construction-Type and Certain Production-Type Contracts,” contract revenues are recognized under the percentage-of-completion method, based on the Company’s engineering estimates of the physical percentage completed for dredging projects and using a cost-to-cost approach for demolition projects.  For dredging projects, costs of contract revenues are adjusted to reflect the gross profit percentage expected to be achieved upon ultimate completion of each dredging project.  For demolition contracts, contract revenues are adjusted to reflect the estimated gross profit percentage.  Provisions for estimated losses on contracts in progress are made in the period in which such losses are determined. Claims for additional compensation due the Company are not recognized in contract revenues until such claims are settled.  Billings on contracts are generally submitted after verification with the customers of physical progress and may not match the timing of revenue recognition.  The difference between amounts billed and recognized as revenue is reflected in the balance sheet as either contract revenues in excess of billings or billings in excess of contract revenues.  Modifications may be negotiated when a change from the original contract specifications is encountered, necessitating a change in project scope or performance methodology and/or material disposal.  Thus, the resulting modification is considered a change in the scope of the original project to which it relates. Significant expenditures incurred incidental to major contracts are deferred and recognized as contract costs based on contract performance over the duration of the related project.  These expenditures are reported as prepaid expenses.

Classification of current assets and liabilities

The Company includes in current assets and liabilities amounts realizable and payable in the normal course of contract completion unless completion of such contracts extends significantly beyond one year.

Cash equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Inventories

Inventories consist mainly of pipe, purchased spare parts, and supplies used in the Company’s dredging operations.  Inventories are stated at the lower of cost or market, using an average cost methodology.

Property and equipment

Capital additions, improvements and major renewals are classified as property and equipment and are carried at cost.  Maintenance and repairs are charged to earnings as incurred.  Depreciation is provided over the estimated useful lives of property and equipment using the straight-line method.  The estimated useful lives by class of assets are 10 years for buildings and improvements, 5 to 10 years for furniture and fixtures, 3 to 10 years for vehicles, dozers and other light operating equipment and systems, and 10 to 30 years for heavy operating equipment, such as barges and dredges.  Leasehold improvements are amortized over the shorter of their remaining useful lives or the remaining lives of the leases.

Goodwill and other intangibles

Goodwill represents the excess of the purchase price of net tangible and intangible assets acquired in business combinations over their estimated fair value.  Other intangibles mainly represent developed technology and databases, customer relationships, and customer contracts acquired in business combinations.  Goodwill resulting from the Transaction is tested annually for impairment in the third quarter of each year, or more frequently should circumstances dictate.

The other intangible assets identified with respect to the Transaction are being amortized over a 7 to 10 year period, except for the intangible assets related to customer contracts, which are being amortized over approximately 13 to 15 months, consistent with the average remaining duration of the underlying contracts.

68

Long-lived assets

Long-lived assets are comprised of property and equipment and intangible assets subject to amortization.  Pursuant to the provisions of SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” long-lived assets to be held and used are reviewed for possible impairment whenever events indicate that the carrying amount of such assets may not be recoverable by comparing the undiscounted cash flows associated with the assets to their carrying amounts.  If such a review indicates an impairment, the carrying amount would be reduced to fair value.  If long-lived assets are to be disposed, depreciation is discontinued, if applicable, and the assets are reclassified as held for sale at the lower of their carrying amounts or fair values less costs to sell.

Asset Retirement Obligations

In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (FIN 47) which is effective for fiscal years ending after December 15, 2005 and is an interpretation of FASB Statement No. 143, “Accounting for Asset Retirement Obligations”. FIN 47 requires recognition of a liability for the fair value of a conditional asset retirement obligation when incurred if the fair value of the liability can be reasonably estimated. Interpretation No. 47 further clarifies what the term “conditional asset retirement obligation” means with respect to recording the asset retirement obligation discussed in SFAS No. 143. The adoption of FIN 47 did not have a material impact on the Company’s consolidated financial position, annual results of operations or cash flows.

Self-insurance reserves

The Company self-insures costs associated with workers’ compensation claims, hull and equipment liability and general business liabilities, up to certain limits.  Insurance reserves are established for estimates of the loss that the Company will ultimately incur on reported claims, as well as estimates of claims that have been incurred but not yet reported.  In determining its estimates, the Company incorporates historical loss experience and judgments about the present and expected levels of cost per claim.  Trends in actual experience are a significant factor in determination of such reserves.

Income taxes

The Company records income taxes based upon SFAS No. 109, “Accounting for Income Taxes,” which requires the use of the liability method of accounting for deferred income taxes.  The provision for

69

income taxes includes federal, foreign and state income taxes currently payable and those deferred because of temporary differences between the financial statement and tax bases of assets and liabilities.

Fair value of financial instruments

The carrying value of financial instruments included in current assets and current liabilities approximates fair values due to the short-term maturities of these instruments.  The carrying value of long-term bank debt is a reasonable estimate of its fair value as interest rates are variable, based on the prevailing market rates.   At December 31, 2005 and 2004, the Company had long-term subordinated notes outstanding with a recorded book value of $175,000.  The fair value of these notes was $157,500 and $157,938 at December 31, 2005 and 2004, respectively, based on quoted market prices.

Minority interest

The Company owns 85% of the capital stock of NASDI, a demolition service provider located in the Boston, Massachusetts area.  The remaining 15% of the capital stock is owned by a senior manager of NASDI.  Minority interest at December 31, 2005 and 2004 reflects the remaining NASDI management stockholder’s 15% non-voting interest in NASDI.

Capital stock

As a result of the sale of the Company (see Note 2), the Company currently has only one class of common stock with a par value of $.01 per share.  500,000 shares are authorized and 1,000 shares are issued and outstanding at December 31, 2005 and 2004.

Reclassifications

In the 2004 consolidated statement of cash flows, $1,925 of distributions from equity joint ventures was reclassified from net cash flows from investing activities to net cash flows from operating activities and $1,242 of capital lease repayments was reclassified from operating activities to net cash flows from financing activities to conform to the 2005 presentation. Also, in the 2003 consolidated statement of cash flows, $2,451 of cash funded to an equipment escrow account was reclassified from net cash flows from operating activities to net cash flows from financing activities and $713 of capital lease repayments was reclassified from operating activities to net cash flows from financing activities to conform to the 2004 presentation.

2.Sale transaction

On December 22, 2003, MDP acquired control of the Company for an initial purchase price of $362,111, including fees and expenses.   The acquisition was financed by new equity contributions of $97,000; term loan and revolver borrowings under a new senior credit facility of approximately $60,300 and $2,000,

70

respectively; the issuance of $175,000 of 7.75% Senior Subordinated Notes due 2013; the rollover of term loan borrowings under a new equipment financing facility of $23,400; the rollover of approximately $1,558 million of capital leases; and cash on hand of $2,853.  As mentioned previously, the sale was accounted for as if it had occurred on December 31, 2003, as management determined that results of operations were not significant and no material transactions occurred during the period from December 23 to December 31, 2003.   The purchase price was subject to certain working capital and debt adjustments to be finalized approximately three months subsequent to the Transaction, as defined per the merger agreement.  The adjustments were finalized in April of 2004, resulting in a decrease to the initial purchase price of $527.

Following is a summary of the fair values of the assets acquired and liabilities assumed as of the date of the acquisition (as revised by the results of third party appraisals and the purchase price adjustment):

Current assets	$	116,584
Property and equipment	263,746
Other intangible assets	7,441
Goodwill	103,563
Other assets	31,391
Total assets acquired	522,725
Current liabilities	56,043
Other liabilities	105,098
Total liabilities assumed	161,141
Total purchase price	$	361,584

The purchase price was allocated to the acquired assets and liabilities based on their fair values at December 31, 2003, as determined by management’s estimates and third-party appraisals, where practicable.   At December 31, 2005, after reviewing for any impairment, goodwill of $79,097 and $19,650 has been assigned to the dredging and demolition reporting units, respectively.   See Notes 5 and 8 regarding the current year impairment of demolition unit goodwill and intangibles.

In connection with the sale, the Company incurred transaction expenses of approximately $23,748, which were reflected in the Company’s 2003 Predecessor Basis statement of operations.  These transaction expenses include sale-related operating expenses of $10,635 for advisory fees and discretionary bonuses paid to management and sale-related financing costs of $13,113 related to the early extinguishment of the Company’s 11¼% senior subordinated notes and write-off of deferred financing costs related to the Company’s prior debt structure. In addition, the Company incurred other acquisition-related costs of approximately $2,691, which were capitalized as direct costs of the Transaction.

	$	(8,108	)	$	(6,706	)

5.Goodwill

In the third quarter of 2005, the Company performed its annual assessment for the impairment of goodwill.  At the time of the Company’s sale transaction in December 2003, a portion of the total goodwill had been allocated to the demolition segment.  Although NASDI achieved its 2005 forecast and is projected to be cash flow positive going forward, Company management does not believe that it will achieve the future returns contemplated in the 2003 forecasts prepared when the goodwill was allocated.  These downward revised projections for the demolition business are attributable to higher anticipated incentive pay to retain a key member of the demolition business’ management.  Based on these revised projections the Company determined there was an impairment of the goodwill related to its demolition reporting unit. Therefore, the Company recorded a non-cash write-down of $4,816 to reflect management’s best estimate, using a discounted cash flow model, of the impairment to goodwill.

73

6.Property and equipment

Property and equipment are as follows:

	2005			2004
Land	$	2,870		$	2,870

	$	240,849		$	256,594

7.Investments in joint ventures

The Company has a 50% ownership interest in Amboy Aggregates (Amboy), whose primary business is the dredge mining and sale of fine aggregate.  The Company accounts for its investment in Amboy using the equity method. The following table includes Amboy’s summarized financial information for the periods presented.

	2005			2004			2003
Current assets	$	7,943		$	7,727		$	6,414
Non-current assets	8,942			8,420			9,367
Total assets	16,885			16,147			15,781
Current liabilities	(1,676		)	(2,160		)	(2,625		)
Non-current liabilities	—			—			(147		)
Equity	$	15,209		$	13,987		$	13,009
Revenue	$	28,363		$	26,773		$	19,316
Costs and expenses	(23,765		)	(22,095		)	(17,412		)
Net income (loss)	$	4,598		$	4,678		$	1,904

Amboy has a loan with a bank, which contains certain restrictive covenants, including limitations on the amount of distributions to its joint venture partners.  It is the intent of the joint venture partners to periodically distribute Amboy’s earnings, to the extent allowed by Amboy’s bank agreement.  The term portion of Amboy’s loan matured in October 2003, and the $2,000 revolving credit facility was set to expire in August 2005.  The revolving credit facility was amended to extend the expiration to August

74

2007 and increase the facility to $3,000.  The Company no longer guarantees any of the outstanding borrowings and accrued interest under the facility.

In 2003, the Company and its Amboy joint venture partner each purchased a 50% interest in land, which is adjacent to the Amboy property and may be used in connection with the Amboy operations.  The Company’s share of the purchase price totaled $1,047 and is reflected in investments in joint ventures.  Income from that land was $29 for the year ended December 31, 2005.

For the years ended December 31, 2005 and 2004, the Company received distributions from Amboy and the adjacent land venture totaling $1,625 and $1,925.

The Company’s 2003 equity from earnings of joint ventures in the statement of income includes a gain of $470 resulting from the Company’s sale of its 20% investment in Riovia S.A., a venture whose sole business was the performance of a dredging contract in Argentina and Uruguay.

8.Intangible Assets

At December 31, 2005, the net book value of intangible assets identified with respect to the Transaction is as follows:

	Estimated			Accumulated
	Life	Cost		Amortization		Net
Customer contract backlog	13 to 15 months	$	4,237	$	4,148	$	89
Demolition customer relationships	7 years	1,093		529		564
Software and databases	7 to 10 years	1,209		283		926
		$	6,539	$	4,960	$	1,579

In the third quarter of 2005, the Company wrote-down the intangible asset related to demolition customer relationships by $902.  This impairment on intangibles was analyzed in conjunction with the goodwill impairment as discussed in Note 5.  When the original customer relationship intangible was established in 2003, it required estimation of future annual revenues attributable to certain key customers.  Over the past two years, the demolition revenues were generated by a greater variety of customers, rather than being as concentrated as anticipated with these key customers.  Therefore, the future revenue expectations related to these particular customers were revised, resulting in this non-cash impairment write-down based on a discounted cash-flow analysis.

75

Amortization expense related to these intangible assets is estimated to be $311 in 2006 and $263 annually in 2007 through 2010.

9.Impairment of land disposal rights

The Company owned rights to dispose a certain quantity of dredged material in upland disposal sites in New Jersey.  During 2003, the site owner informed Company management that it did not intend to make future disposal sites available for the Company to utilize its disposal rights.  Therefore, management determined that recovery of the land rights at their recorded amount was unlikely and recorded an impairment loss of $2,276.

10.Other non-current assets

At December 31, 2005 and 2004, other non-current assets includes $1,575 of cash held in a new escrow account as security for the Company’s lease rental obligations under one of its long-term equipment operating leases.  This cash will be released once the Company achieves certain financial thresholds, or upon conclusion of the lease.

11.  Accrued expenses

Accrued expenses are as follows:

	2005		2004
Payroll and employee benefits	$	8,927	$	4,700
Insurance	6,387		5,022
U.S. income and other taxes	3,170		2,564
Interest rate swap liability	1,598		662
Interest	1,115		799
Equipment leases	933		719
Demolition litigation expense	—		1,275
Other	2,134		1,935
	$	24,264	$	17,676

76

12.Long-term debt

Long-term debt is as follows:

	2005			2004
Senior bank debt:
Equipment term loan	$	19,500		$	21,450
Term loan B	54,300			57,800
Revolving loan	2,000			—
7 ¾% senior subordinated notes	175,000			175,000
	250,800			254,250
Current maturities of long-term debt	(1,950		)	(1,950		)
	$	248,850		$	252,300

In December 2003, the Company entered into a long-term loan with an equipment financing company (Equipment Term Loan) to refinance borrowings incurred under its former revolving credit facility to acquire certain equipment that was previously under an operating lease.  Principal payments under the Equipment Term Loan total $1,950 annually for each of the next nine years and are paid in quarterly installments.  Interest is paid quarterly at a variable LIBOR-based rate.   The Equipment Term Loan agreement also contains provisions that require the Company to maintain certain financial ratios.   Borrowings under the Equipment Term Loan are secured by first lien mortgages on certain operating equipment with a net book value of $20,348 at December 31, 2005.

In connection with the sale, in December 2003, the Company also entered into a new bank credit agreement (Credit Agreement) with a group of banks, consisting of a Tranche B Term Loan facility, which matures in 2010, and a $60,000 aggregate revolving credit facility which may be used for borrowings or for letters of credit, which expires in 2008.  The terms of the Credit Agreement provide for interest rate spreads based on the Company’s debt level compared to earnings, as defined, and allow for various interest rate options for loan amounts and periods that are selected at the discretion of the Company.  Borrowings under the Credit Agreement are secured by first lien mortgages on certain operating equipment of the Company with a net book value of $80,309 at December 31, 2005 and are guaranteed by all domestic subsidiaries of the Company.   The Credit Agreement also contains provisions requiring the Company to maintain certain financial ratios and restricting the Company’s ability to pay dividends, incur indebtedness, create liens, and take certain other actions.

Effective September 30, 2004, the Company amended its Credit Agreement and Equipment Term Loan (collectively, Senior Credit  Facilities) to allow additional flexibility in its leverage and interest coverage ratios, including replacement of the total leverage ratio with a required minimum EBITDA, as defined in

77

the aforementioned agreements, through 2005.  In exchange, the Company’s capital spending limits were reduced and the Company’s borrowing availability under its revolving credit facility was reduced to $45,000 (with a sub-limit of $35,000 for letters of credit and $15,000 for revolver borrowings), until such time that the Company achieves certain defined financial measures.  At December 31, 2005, the Company had $20,147 in undrawn letters of credit relating to foreign contract performance guarantees and insurance payment liabilities and $2,000 borrowed under the revolver.  Therefore, at December 31, 2005, the Company had availability of $22,853 (with a sub-limit of $14,853 for the letters of credit and $13,000 for revolver borrowings).  At December 31, 2005, the Company was in compliance with its various covenants under its revised Senior Credit Facilities.

Effective February 1, 2006, the Company’s borrowing availability reverted back to the full $60,000 allowed under the original terms of its Credit Agreement with its senior lenders, based on the attainment of the certain defined financial measures in accordance with the terms of the September 2004 amendment to such credit agreement.  Additionally, on March 22, 2006 the Company amended its Credit Agreement to increase its sub-limit for letters of credit to $45 million from $35 million.

The Company is required to pay all unpaid principal amounts of its term loan B facility in full at maturity.   Annual prepayments of principal may be required to the extent the Company reduces collateral and voluntary prepayments are allowed.   In 2005 and 2004, the Company made voluntary prepayments of $3,500 and $2,500, respectively.

At December 31, 2005 and 2004, the Company’s weighted average borrowing rate under its Senior Credit Facilities was 7.9% and 6.4%, respectively.  Amortization of financing fees related to the Senior Credit Facilities added 1.0% to the 2005 weighted average borrowing rate.  The Company also pays an annual commitment fee of up to 0.750% on the average daily unused capacity available under the revolving credit facility.

On December 22, 2003, the Company issued $175,000 of 7¾% senior subordinated notes (Notes) which will mature on December 15, 2013. The Notes are general unsecured obligations of the Company, subordinated in right of payment to all existing and future senior debt, including borrowings under the Senior Credit Facilities. The Company’s obligations under the Notes are guaranteed on a senior subordinated basis by all of the Company’s domestic subsidiaries.

The Company used the proceeds from its new debt, along with equity contribution from its new owners, to provide consideration to its former owners, as well as repay its former debt, including its 11¼% senior subordinated notes due August 15, 2008.  In connection with the extinguishment of these notes in December of 2003, the Company paid tender and call premiums totaling $9,359, which are reflected as

78

sale-related financing costs in the 2003 consolidated statement of operations. Additionally, in connection with the extinguishment of its old debt structure, the Company wrote off deferred financing costs totaling $3,754, which is also reflected as sale-related financing costs in the 2003 consolidated statement of operations.

Financing fees and amendment fees related to the Senior Credit Facilities and the Notes are deferred and amortized over the respective terms of the borrowings.

The schedule of principal payments required under the Company’s long-term debt at December 31, 2005 is as follows:

2006	$	1,950
2007	1,950
2008	3,950
2009	1,950
2010	1,950
Thereafter	239,050
	250,800
Less current portion	(1,950		)
	$	248,850

The Company sometimes enters into capital lease arrangements to finance the acquisition of dozers, excavators and automobiles.  The current portion of capital lease obligations, in the amounts of $933 and $719, is included in accrued expenses at December 31, 2005 and 2004, respectively.  The long-term portion of these leases is included in other long-term liabilities and totaled $992 and $1,140, respectively.   The terms of these leases extend through 2008.  The net book value of these assets was $2,598 and $1,676 at December 31, 2005 and 2004, respectively.

13.Risk management activities

The Company uses derivative instruments to manage commodity price, interest rate, and foreign currency exchange risks.  Such instruments are not used for trading purposes.  As of December 31, 2005, the Company is party to various swap arrangements to hedge the price of a portion of its diesel fuel purchase requirements for work in its backlog to be performed through May 2006.  As of December 31, 2005, there were 2.5 million gallons remaining on these contracts.  Under these agreements, the Company will pay fixed prices ranging from $1.48 to $1.99 per gallon.  At December 31, 2005 and 2004, the fair value of these contracts was estimated to be a liability of $344 and $36, respectively, based on quoted market prices.  The fair value at December 31, 2005 and 2004 is recorded in accrued liabilities on the balance sheet.

79

The Company has designated its fuel hedge arrangements as cash flow hedges, resulting in the following activity in accumulated other comprehensive (loss), net of income taxes:

	2005			2004
Accumulated other comprehensive income as of January 1	$	(22	)	$	—
Net gains reclassified into costs of contract revenues from accumulated other comprehensive income, net of tax	(1,838		)	(1,654		)
Change in fair value of derivatives, net of tax	1,651			1,632
Accumulated other comprehensive loss as of December 31	$	(209	)	$	(22	)

Ineffectiveness related to these fuel hedge arrangements was determined to be immaterial.  The remaining gains or losses included in accumulated other comprehensive loss at December 31, 2005 will be reclassified into earnings over the next five months, corresponding to the period during which the hedged fuel is expected to be utilized.

In February 2004, the Company entered into an interest rate swap arrangement to swap a notional amount of $50,000 from a fixed rate of 7.75% to a floating LIBOR-based rate in order to manage the interest rate paid with respect to the Company’s 7¾% senior subordinated notes.  The fair value of the swap at December 31, 2005 was a liability of $1,598 and is recorded in accrued expenses.  The swap is not accounted for as a hedge; therefore, the changes in fair value are recorded as adjustments to interest expense in each reporting period.  In 2005 the Company made settlement payments under the swap totaling $245, which are recorded as interest expense and in 2004, the Company received settlement payments under the swap totaling $526, which are recorded as a reduction to interest expense.

The Company had no foreign currency hedge contracts outstanding at December 31, 2005 or 2004.

14.Income taxes

The provision (benefit) for income taxes is as follows:

							Predecessor
	Successor Basis						Basis
	2005			2004			2003
Federal:

Other	(163		)	95			416
Income tax (benefit) provision	$	(1,364	)	$	(4,366	)	$	1,318

During the third quarter of 2005, the Company performed its annual assessment for the impairment of goodwill related to its demolition business.  Based upon the results of this assessment the Company recorded a non-cash write-down of $4,816 which impacted the federal tax provision for the year ended December 31, 2005, as noted above.

For the year ended December 31, 2005, the Company’s income tax provision includes foreign income tax expense of $159 and interest expense of $96 resulting from the settlement of a foreign tax obligation related to the 1999 taxable year.

At December 31, 2005 and 2004, the Company had net operating loss carryforwards for federal income tax purposes of approximately $4,854 and $15,049, respectively, which will expire in 2024. At

December 31, 2005 and 2004 the Company had net operating loss carryforwards for state income tax purposes totaling $6,948 and $11,307 respectively, which will expire between 2010 and 2024.

The Company has recorded reserves for contingent income tax liabilities with respect to loss contingencies that are deemed probable of occurrence.  Such amounts total $3,120 and are included in income taxes payable at December 31, 2005.  These loss contingencies relate primarily to the classification of transaction expenses incurred in connection with the Company’s sale in December 2003, the taxation of foreign earnings, and state income tax issues.

The Company’s deferred tax assets (liabilities) are as follows:

	Successor Basis
	2005			2004
Net deferred tax assets:
Accrued liabilities	$	5,321		$	6,046
Net operating loss carry-forward benefit	2,188			5,729

As reported in the balance sheet:
Net current deferred tax assets (included in other current assets)	$	4,953		$	5,413
Net non-current deferred tax liabilities	(88,154		)	(90,429		)
Total net deferred tax liabilities	$	(83,201	)	$	(85,016	)

15.Lease commitments

The Company leases certain operating equipment and office facilities under long-term operating leases expiring at various dates through 2020.  The equipment leases contain renewal or purchase options that specify prices at the then fair market value upon the expiration of the lease terms.  The leases also contain default provisions that are triggered by an acceleration of debt maturity under the terms of the Company’s Credit Agreement, and one lease arrangement requires that the Company maintain certain financial ratios comparable to those required by its Senior Credit Facilities.  Additionally, the leases typically contain provisions whereby the Company indemnifies the lessors for the tax treatment attributable to such leases based on the tax rules in place at lease inception.  The tax indemnifications do not have a contractual dollar limit.  To date, no lessors have asserted any claims against the Company under these tax indemnification provisions.

82

Future minimum operating lease payments for the years ending December 31 are as follows:

2006	$	14,172
2007	13,464
2008	12,794
2009	11,527
2010	8,201
Thereafter	53,981
Total minimum lease payments	$	114,139

Total rent expense under long-term operating lease arrangements for the years ended December 31, 2005, 2004 and 2003 was $16,344, $15,109 and $17,397, respectively.  This excludes expenses for equipment and facilities rented on a short-term, as-needed basis.

16.Retirement plans

The Company sponsors two 401(k) savings plans, one covering substantially all non-union salaried employees (Salaried Plan) and the second covering its non-union hourly employees (Hourly Plan).  Under both plans, individual employees may contribute a percentage of compensation and the Company will match a portion of the employees’ contributions. Additionally, the Salaried Plan includes a profit-sharing component, permitting the Company to make discretionary employer contributions to all eligible employees of the Salaried Plan.  The Company’s expense for matching and discretionary contributions for 2005, 2004 and 2003 was $2,944, $1,975 and $2,879, respectively.  On January 1, 2003, the Company adopted a third 401(k) savings plan specifically for employees that are members of the Company’s tugboat union. Participation in and contributions to this plan are not significant.

The Company also contributes to various multi-employer pension plans pursuant to collective bargaining agreements. In the event of a plan’s termination or Company withdrawal from a plan, the Company may be liable for a portion of the plan’s unfunded vested benefits.  As of December 31, 2005, unfunded amounts, if any, are not significant.  Total contributions to multi-employer pension plans for the years ended December 31, 2005, 2004 and 2003 were $5,218, $4,410 and $5,000, respectively.

17.Segment information

The Company and its subsidiaries currently operate in two reportable segments:  dredging and demolition. The Company’s financial reporting systems present various data for management to run the business, including profit and loss statements prepared according to the segments presented. Segment information for 2005, 2004 and 2003 is provided as follows:

Total	$	374,262	$	313,807	$	360,830

The Company derived revenues and gross profit from foreign project operations for the years ended December 31 as follows:

							Predecessor
	Successor Basis						Basis
	2005			2004			2003
Contract revenues	$	47,402		$	62,862		$	60,922

Gross profit	$	4,336		$	8,400		$	3,992

The majority of the Company’s long-lived assets are marine vessels and related equipment.  At any point in time, the Company may employ certain assets outside of the U.S., as needed, to perform work on the Company’s foreign projects.  As of December 31, 2005 long-lived assets with a net book value of $48,878 were employed outside of the U.S.

Certain foreign projects performed by the Company have warranty periods, typically spanning no more than three to five years beyond project completion, whereby the Company retains responsibility to maintain the project site to certain specifications during the warranty period.  Generally, any potential liability of the Company is mitigated by insurance, shared responsibilities with consortium partners, and/or recourse to owner-provided specifications.   The Company does not anticipate having to perform under its warranty provisions; therefore, no liability has been reflected at December 31, 2005 or 2004 related to its potential warranty obligations.

18.Concentrations of risk

The Company’s primary dredging customer is the U.S. Army Corps of Engineers (the Corps), which has responsibility for federally funded projects related to navigation and flood control.  In 2005, 2004 and 2003, 70.2%, 67.2% and 65.3%, respectively, of contract revenues were earned from dredging contracts with federal government agencies, including the Corps as well as other federal entities such as the U.S.

85

Coast Guard and U.S. Navy.  At December 31, 2005 and 2004, approximately 62.7% and 68.2%, respectively, of accounts receivable, including contract revenues in excess of billings, were due on dredging contracts with federal government agencies.   The Company depends on its ability to continue to obtain federal government dredging contracts, and indirectly, on the amount of federal funding for new and current government dredging projects.  Therefore, the Company’s dredging operations can be influenced by the level and timing of federal funding.

19.Commitments and contingencies

Performance and bid bonds are customarily required for dredging and marine construction projects, as well as some demolition projects.  The Company obtains its performance and bid bonds through a bonding agreement with a surety company that has been granted a security interest in a substantial portion of the Company’s operating equipment with a net book value of $83.5 million at December 31, 2005.  The bonding agreement contains provisions requiring the Company to maintain certain financial ratios and restricting the Company’s ability to pay dividends, incur indebtedness, create liens, and take certain other actions.  The bonding agreement was amended effective September 30, 2004 to revise the minimum net worth requirements.  At December 31, 2005, the Company was in compliance with its various covenants under the bonding agreement, as revised.  Bid bonds are generally obtained for a percentage of bid value and amounts outstanding typically range from $5 to $10 million.  At December 31, 2005, the Company had outstanding performance bonds valued at approximately $330 million; however, the revenue value remaining in backlog related to these projects totaled approximately $155 million.

As is customary with negotiated contracts and modifications or claims to competitively-bid contracts with the federal government, the government has the right to audit the books and records of the Company to ensure compliance with such contracts, modifications or claims and the applicable federal laws.  The government has the ability to seek a price adjustment based on the results of such audit.  Any such audits have not had and are not expected to have a material impact on the financial position, operations or cash flows of the Company.

In the normal course of business, the Company is a defendant in various legal proceedings.  Except as described below, the Company is not currently a party to any material legal proceedings or environmental claims.

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

86

continues to comply 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.

In 1999, the Boston Housing Authority (“BHA”), for whom the Company’s demolition business, NASDI, had worked, asserted that NASDI and its subcontractors were responsible for improperly disposing of some contaminated materials. At the time the Company acquired NASDI in 2001, it was believed that NASDI had sufficient recourse in the matter and that any potential liability would be minimal.  However, since 2001, certain of the insurance carriers that would be responsible for this matter have gone bankrupt.  Negotiations between the parties have continued to progress, and in the third quarter of 2004, the case went before a judge in the Massachusetts court system who advised NASDI and the subcontractors to accept a settlement with the BHA.  Therefore, in the third quarter of 2004, the Company recorded a $1.3 million charge for NASDI’s share of this potential settlement liability.  This final settlement was paid in the fourth quarter of 2005.   Company management believes there is no further liability to the Company related to this matter.

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.

On August 15, 2003 a claim was brought in the Landesgericht (District Court) of Berlin, Germany against Great Lakes by Hafemeister Erd-und Tiefbau GmbH, a German construction Company.  On June 8, 2004 Great Lakes was served with notice of this claim, alleging that in 2000 the Company along with a Dutch company wrongfully withdrew from a consortium prior to the submission of a tender for a project to be performed in Germany.  The claimant is seeking damages from its inability to bid on or perform the works in the amount of approximately €21,000.  Great Lakes filed a petition with the German courts to seek dismissal of the claim for lack of factual and legal merit.  A hearing occurred in December 2005 and

87

the claim was dismissed. Although the claimant has the right to appeal the dismissal, Company management believes there will be no liability to the Company related to this matter.

20.Subsidiary guarantors

The payment obligations of the Company under its 7¾% senior subordinated notes are guaranteed by all of the Company’s domestic subsidiaries (Subsidiary Guarantors).  Such guarantees are full, unconditional and joint and several.  Separate financial statements of the Subsidiary Guarantors are not presented because the Company’s management has determined that they would not be material to investors. The following supplemental financial information sets forth, on a combined basis, the balance sheets, statements of operations and statements of cash flows for the Subsidiary Guarantors, the Company’s non-guarantor subsidiary and for the Great Lakes Dredge & Dock Corporation (GLD Corporation).

Report of Independent Public Accountants

To the Partners

Amboy Aggregates

We have audited the accompanying balance sheet of Amboy Aggregates (A Joint Venture) as of December 31, 2003, and the related statements of operations and partners’ capital and cash flows for each of the two years in the period ended December 31, 2003. These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits 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 audits provide 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 Amboy Aggregates (A Joint Venture) as of December 31, 2003, and its results of operations and cash flows for each of the two years in the period ended December 31, 2003, in conformity with accounting principles generally accepted in the United States of America.
