About Orion

We are a leading marine specialty contractor serving the heavy civil marine infrastructure market. We provide a broad range of marine construction services on, over and under the water along the Gulf Coast, the Atlantic Seaboard and the Caribbean Basin. Our customers are federal, state and municipal governments as well as private commercial and industrial enterprises. We are headquartered in Houston, Texas.

We act as a single-source, turnkey solution for our customers’ marine contracting needs. Many of our contracts encompass multiple services within a single project. Our heavy civil marine construction services include marine transportation facility construction, such as cruise ship terminals and cargo wharves, docks and marinas, marine pipeline construction, bridges and causeways, and marine environmental structures. In addition, we provide dredging, repair and maintenance, and other specialty services. Projects involving dredging generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand, or rock. Our specialty services include salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair. While we bid on projects up to and in excess of $50.0 million, during 2008 our average revenue per project was between $1.0 million and $3.0 million. Projects we bid on can take up to 36 months to complete, but the typical duration of our projects is from three to nine months. In 2008, our services were predominantly provided under fixed-price contracts, measured by revenue, and we self-performed over 88% of our work, measured by cost.

We focus on selecting higher margin projects on which to work, controlling the critical path items of a contract by self-performing most of the work, managing the profitability of a contract and rewarding project managers for outperforming the estimated costs to complete projects. We use scalable enterprise-wide project management software to integrate functions such as estimating project costs, managing financial reporting and forecasting profitability.

Our revenue grew from $101.4 million in 2003 to $261.8 million in 2008, a compounded annual growth rate, or CAGR, of 20.9%, substantially all of which was organic. During that same period, our EBITDA grew from $15.3 million in 2003 to $41.3 million in 2008, a CAGR of 22.0%, and our income available to common stockholders increased from $4.9 million in 2003 to $14.5 million in 2008, a CAGR of 24.2%. For an explanation of EBITDA and a reconciliation of EBITDA to net income calculated and presented in accordance with generally accepted accounting principles, or GAAP, please see “Summary Consolidated Financial Data — Non-GAAP Financial Measures.”

Our growth has been driven by our ability to capitalize on increased infrastructure spending in our markets across our scope of operations. We believe that the demand for our infrastructure services has been, and will continue to be, driven and funded primarily by a wide variety of factors and sources including the following:

TABLE OF CONTENTS

We believe the diversity of our end market drivers and funding sources as well as our ability to provide a broad range of services result in a less volatile revenue stream year-to-year.

At June 30, 2009, our backlog under contract was approximately $141.8 million, compared with $152.1 million at June 30, 2008. Given the typical duration of our contracts, which ranges from three to nine months, our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve-month period. In addition to our backlog, we also have a substantial number of projects in negotiation or pending award at any given time. We expect to continue to grow our business organically, as well as selectively consider strategic acquisitions that improve our market position within our existing markets, expand our geographic footprint and increase our portfolio of services.

We expect to continue to grow our business organically, as well as selectively consider strategic acquisitions that improve our market position within our existing markets, expand our geographic footprint and/or increase our portfolio of services. For example, in 2006 we expanded our presence along the Gulf Coast by acquiring substantially all of the operations of F. Miller and Sons, LLC, a marine construction company based in Lake Charles, Louisiana. In 2008, we expanded our dredging capabilities along the Atlantic Seaboard through the purchase of substantially all of the assets of Subaqueous Services, Inc., and we established a permanent office and yard in Jacksonville, Florida. In addition, we established a permanent construction office in the Norfolk, Virginia area in 2008.

As of June 30, 2009, we had 1,063 employees, 238 of whom were full-time salaried personnel. Our employees are not represented by any labor unions. Our workforce is supported by a large fleet of specialty equipment, substantially all of which we own. We have built much of our most highly specialized equipment, including many of our dayboats, tenders and dredges, and we provide maintenance and repair service to our entire fleet. Our fleet is highly mobile, which enables us to easily relocate our specialized equipment to and across all of the regions that we serve.

Competitive Strengths

We believe we have the following competitive strengths:

Breadth of Capabilities.  Unlike many of our competitors, we provide a broad range of marine construction services for our customers. These services include marine transportation facility construction, dredging, repair and maintenance, bridge building and marine pipeline construction, as well as specialty services. Our specialty services include salvage, demolition, diving and underwater inspection, excavation and repair. By offering a breadth of services, we act as a single-source provider with a turnkey solution for our customers’ marine contracting needs. We believe this distinguishes us from smaller, local competitors, giving us an advantage in competitive bidding for certain projects. Furthermore, we believe our broad service offering and ability to complete smaller projects strengthens our relationships with our customers.

Experienced Management Team.  Our executive officers and senior project managers have an average of 29 years of experience in the heavy civil construction industry, an average of 27 years of experience in the heavy civil marine infrastructure industry, and an average of 19 years of experience with us and our predecessor companies. Our strong management team has driven operational excellence for us, as demonstrated by our high organic growth, disciplined bidding process, and what we believe to be industry-leading margins. We believe our management has fostered a culture of loyalty, resulting in high employee retention rates.

TABLE OF CONTENTS

High Quality Fleet and Marine Maintenance Facilities.  We operate and maintain almost 400 vessels and pieces of specialized equipment, substantially all of which we own, that include spud and material barges, cutter section dredges, dayboats, pushboats, tugs, and crawler and hydraulic cranes.

We are capable of building, and have built, much of our highly specialized equipment and we provide maintenance and repair service to our entire fleet. During 2006 we manufactured a dredge, which can operate on either diesel fuel or electric power, allowing us to complete projects with specified limits on nitrogen oxide emissions. Because some of our equipment operates 24 hours a day, seven days a week, it is essential that we are able to minimize equipment downtime. We achieve this by operating our own electrical and machine shops, stocking long-lead spares, and staffing maintenance teams on-call 24 hours a day, seven days a week to handle repair emergencies. We also own and maintain a dry dock facility, which reduces our equipment downtime and dependence on third party facilities. We have primary field offices in Channelview, Texas, Port Lavaca, Texas, Lake Charles, Louisiana, Tampa, Florida, and Jacksonville, Florida; most of which are located on waterfront properties and allow us to perform repair and maintenance activities on our equipment and to mobilize and demobilize equipment to and from our projects in a cost efficient manner.

Financial Strength.  Financial strength is often an important consideration for many customers in selecting infrastructure contractors and directly affects our bonding capacity. In 2008, approximately 38% of our projects, measured by revenue, required some form of bonding. Most of our competitors are smaller, local companies with limited bonding capacity. As of June 30, 2009, we had cash on hand of $44.0 million. Our revenue increased by 24.5% from $210.4 million in 2007 to $261.8 million in 2008. Our revenue in the first half of 2009 was $140.8 million. We believe our financial strength and bonding capacity provide us with the flexibility to bid on larger projects and more projects than many of our smaller competitors with less bonding capacity.

Self-Performance of Contracts.  In 2008, we self-performed approximately 88% of our marine construction and dredging projects, measured by cost, meaning that we performed the projects using our own employees and equipment instead of using external subcontractors. By self-performing our contracts, we believe we can more effectively manage the costs and quality of each of our projects, thereby better serving our customers and increasing our profitability. Our breadth of capabilities and our high quality fleet give us the ability to self-perform our contracts, which we believe distinguishes us from many of our competitors, who often subcontract significant portions of their projects.

Project Selection and Bidding Expertise.  We were founded in 1994 as a marine construction project management business, and our roots as a project management business have served us well, creating a project management culture that is pervasive throughout our organization. We focus on selecting the right projects on which to bid, controlling the critical path items of a contract by self-performing the work and managing the contract profitably by appropriately structuring rewards for project managers. Our intense focus on profitably executing contracts has resulted in only a small number of unprofitable contracts since our founding. We use scalable, enterprise-wide project management software to integrate functions such as estimating project costs, managing financial reporting and forecasting profitability.

Strong Market Presence.  We believe we are a market leader in most of our primary markets. We believe our operations are strategically located to benefit from favorable industry trends, including increasing port expansion and maintenance, highway funding, coastal restoration, and hurricane restoration and repair activity. For example, the Port of Houston, one of the largest ports in the United States, and the Port of Tampa and their adjacent private industry customers generate both new marine construction and annual maintenance of existing dock facilities. In addition, the Texas Gulf Coast does not have any natural deep water ports, requiring all of its channels and ports to depend significantly on maintenance dredging, which is a significant source of recurring revenue. Our strong market presence allows us to more efficiently deploy and mobilize our equipment throughout the areas in which we operate.

TABLE OF CONTENTS

Business Strategy

We intend to use the following strategies to increase revenue:

Expand and Fill in Our Service Territory.  We intend to continue to grow our business by seeking opportunities in other geographic markets by establishing a physical presence in new areas through selective acquisitions or greenfield expansions. Over the last several years, we have successfully expanded our services into Florida, the Caribbean Basin and Louisiana through strategic acquisitions. We have also pursued greenfield growth opportunities on the Atlantic Seaboard by opening a Jacksonville, Florida office and on the Gulf Coast by opening a Corpus Christi, Texas office. We believe that the establishment of a geographic base improves our returns within a given market, reducing mobilization and demobilization costs, improving and increasing capacity utilization and improving work force economics and morale. We continue to focus on establishing bases in our geographic markets with solid, long-term fundamentals. In particular, between 2006 and 2008 we established additional operating bases in two geographic regions: along the Gulf Coast between Texas and Florida and along the Atlantic Seaboard, working north from Florida to the Chesapeake Bay. In the longer term, we intend to establish a presence in the Mississippi River System and on the West Coast and New England Coast of the United States.

Pursue Strategic Acquisitions.  We intend to evaluate acquisition opportunities in parallel with our greenfield expansion or which are in complementary or related fields. Our strategy will include timely and efficient integration of such acquisitions into our culture, bidding process and internal controls. We believe that attractive acquisition candidates are available due to the highly fragmented and regional nature of the industry, high cost of capital for equipment and the desire for liquidity among an aging group of existing business owners. We believe our financial strength, industry expertise and experienced management team will be attractive to acquisition candidates.

Continue to Capitalize on Favorable Long-Term Industry Trends.  Our growth has been driven by our ability to capitalize on increased infrastructure spending across the multiple end-markets we serve including port infrastructure, government funded projects, transportation, oil and gas, and environmental restoration markets. We believe these long-term industry trends, described in more detail in “Business — Industry Overview” in our 2008 Form 10-K, have significantly contributed to the funding and demand for our infrastructure services. This increased spending has caused shortages of specialized equipment and labor, creating a favorable bidding environment for heavy civil marine projects. We believe we are well-positioned to continue to benefit from these long-term industry trends.

Continue to Reinvest in Our Core Business.  Since our inception, we have focused on pursuing technically complex projects where our specialized services and equipment differentiate us from our competitors. Our breadth of services and ability to self-perform a high percentage of our projects has enabled us to better and more cost-effectively serve our customers’ needs. We intend to continue to enhance our operating capabilities across all of our present and future markets in order to better serve our customers and further differentiate ourselves from our competitors. For example, we intend to expand our heavy lift equipment capability, increase our boat and barge fleet, including ocean-going vessels, and increase our dry-dock resources.

History

We were founded in 1994 as a marine construction project management business. Initially, we performed work along the continental U.S. coastline, as well as in Alaska, Hawaii and the Caribbean Basin, and our revenue grew to $14.4 million in 1996.

To improve our financial and competitive position, we decided in 1997 to expand beyond the project management business by establishing fixed geographic operating bases. Between 1997 and 2003 we invested approximately $30.0 million in four acquisitions to broaden our operating capabilities and geographic footprint, and our revenue grew to $101.4 million in 2003.

In 2004, we were acquired by Orion Marine Group, Inc. (formerly known as Hunter Acquisition Corp., a corporation formed and controlled by our former principal stockholders), and we incorporated under the laws of the State of Delaware.

TABLE OF CONTENTS

In September 2006, we acquired the assets of F. Miller Construction, based in Lake Charles, Louisiana, to serve as a platform for expansion within Louisiana and other Gulf Coast markets. F. Miller Construction was originally founded in 1932 and performs specialty marine construction projects, bridge construction projects, and complex sheet pile installations for both government and private industry customers.

In March and April 2007, we revised our subsidiary and holding company structure, and in May 2007, we completed a private placement of our common stock pursuant to Rule 144A through which we redeemed all of the shares of our former principal stockholders. In August 2007, we filed a Registration Statement on Form S-1 registering shares of common stock held by the selling stockholders identified therein, which became effective in December 2007.

In February 2008, we acquired substantially all of the assets of Subaqueous Services, Inc. which expanded our dredging capabilities along the Atlantic Seaboard.

Our common stock commenced trading publicly in December 2007 and is currently listed on the New York Stock Exchange under the symbol “ORN.”

TABLE OF CONTENTS

SUMMARY CONSOLIDATED FINANCIAL DATA

The following table sets forth certain of our summary consolidated financial information for the periods represented. The financial data as of and for each of the three years in the period ended December 31, 2008 has been derived from our audited consolidated financial statements and notes thereto, which have been audited by Grant Thornton LLP, contained in our 2008 Form 10-K. The share and per share financial data presented below has been adjusted to give effect to the 2.23 for one reverse split of our common stock that we effected on May 17, 2007.

In October 2004, we were acquired by Orion Marine Group, Inc., formerly known as Hunter Acquisition Corp., a corporation formed and controlled by our former principal stockholders. For accounting purposes, our company as it existed until the time we were acquired by Hunter Acquisition Corp. is referred to as our “Predecessor” and our company as it has existed since the acquisition is referred to as our “Successor.” Concurrent with the acquisition and in accordance with GAAP, we wrote up the value of our assets to their current market value (as determined by appraisals for certain of our assets, such as equipment and land) at the time of the transaction. The result of this write up increased the book value of our assets and the associated depreciation expense. Therefore, depreciation expense for our Predecessor was less than depreciation expense for our Successor.

Historical results are not necessarily indicative of results we expect in future periods. The data presented below should be read in conjunction with, and are qualified in their entirety by reference to, “Capitalization” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this prospectus supplement, “Selected Financial Data” in our 2008 Form 10-K, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and the notes thereto included in our 2008 Form 10-K and in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2009 and June 30, 2009, which are incorporated by reference in the accompanying prospectus.

The following table includes the non-GAAP financial measure of EBITDA. For a definition of EBITDA and a reconciliation to net income calculated and presented in accordance with GAAP, please see “— Non-GAAP Financial Measures.”

TABLE OF CONTENTS

Non-GAAP Financial Measures

We include in this prospectus supplement the non-GAAP financial measure of EBITDA. We define EBITDA as income before interest, income taxes, depreciation and amortization. EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements such as investors, commercial banks and others, to assess:

EBITDA is not a presentation made in accordance with GAAP. EBITDA should not be considered an alternative to, or more meaningful than, net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP as measures of operating performance, liquidity or ability to service debt obligations. Because EBITDA excludes some, but not all, items that affect net income and is defined differently by different companies in our industry, our definition of EBITDA may not be comparable to similarly titled measures of other companies. EBITDA has important limitations as an analytical tool, and you should not consider it in isolation.

The following table provides a reconciliation of EBITDA to our net income for the periods indicated as calculated and presented in accordance with GAAP:

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and under “Risk Factors” in Item 1A of our 2008 Form 10-K, in addition to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. Realization of these risks could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Risk Factors Relating to Our Business

For a discussion of the risks and uncertainties related to our business, please read “Risk Factors” in Item 1A of our 2008 Form 10-K, which is incorporated by reference in the accompanying prospectus.

Risk Factors Relating to Our Accounting, Financial Results and Financing Plans

For a discussion of the risks and uncertainties related to our accounting, financial results and financing plans, please read “Risk Factors” in Item 1A of our 2008 Form 10-K, which is incorporated by reference in the accompanying prospectus.

Risk Factors Relating to Our Common Stock

Future sales of our common stock in the public market or the issuance of securities senior to our common stock could adversely affect the trading price of our common stock and our ability to raise funds in new stock offerings. In addition, you may experience dilution of your ownership interests if we issue additional shares of our common stock in the future.

Sales by us or our stockholders of a substantial number of shares of our common stock in the public markets following this offering, or the perception that these sales might occur, could cause the market price of our common stock to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities.

We may issue common stock or equity securities senior to our common stock in the future for a number of reasons, including financing our operations and business strategy, to reduce our indebtedness, to satisfy our obligations upon the exercise of options or for other reasons. We cannot predict the effect, if any, that future sales or issuance of shares of our common stock or other equity securities, or the availability of shares of common stock or such other equity securities for future sale or issuance, will have on the trading price of our common stock.

Any issuance of additional shares could result in the dilution of the ownership interests of our present stockholders and purchasers of our common stock offered hereby. We are currently authorized to issue 50,000,000 shares of common stock and 10,000,000 shares of preferred stock with such designations, preferences and rights as determined by our board of directors. As of August 12, 2009, there were 21,930,415 shares of our common stock outstanding.

The price of our common stock may fluctuate significantly, which could negatively affect us and holders of our common stock.

The trading price of our common stock may fluctuate significantly in response to a number of factors, many of which are beyond our control. Some of the facts that could negatively affect our share price include:

TABLE OF CONTENTS

In addition, the U.S. securities markets have experienced significant price and volume fluctuations. These fluctuations often have been unrelated to the operating performance of companies in these markets. Market fluctuations and broad market, economic and industry factors may negatively affect the price of our common stock, regardless of our operating performance. You may not be able to sell your shares of our common stock at or above the public offering price, or at all. Any volatility of or a significant decrease in the market price of our common stock could also negatively affect our ability to make acquisitions using common stock. Further, if we were to be the object of securities class action litigation as a result of volatility in our common stock price or for other reasons, it could result in substantial costs and diversion of our management’s attention and resources, which could negatively affect our financial results.

We do not anticipate paying any dividends on our common stock in the foreseeable future.

We have not historically paid dividends and do not intend to declare or pay any cash or other dividends on our common stock in the foreseeable future. For the foreseeable future, we intend to retain earnings, if any, to grow our business. Payments of future dividends, if any, will be at the discretion of our board of directors and will depend on many factors, including general economic and business conditions, our strategic plans, our financial results and condition, legal requirements, and other factors as our board of directors deems relevant. Our existing credit facility and bonding facility restrict our ability to pay cash dividends on our common stock, and we may also enter into credit agreements or other bonding or borrowing arrangements in the future that will restrict our ability to declare or pay cash dividends on our common stock.

Our common stock is subject to restrictions on foreign ownership.

We are subject to government regulations pursuant to the Dredging Act, the Jones Act, the Shipping Act and the Vessel Documentation Act. These statutes require vessels engaged in the transport of merchandise or passengers or dredging in the navigable waters of the United States to be owned and controlled by U.S. citizens. The U.S. citizenship ownership and control standards require the vessel-owning entity to be at least 75% U.S. citizen owned. Our certificate of incorporation provides that any transfer, or attempted or purported transfer, of any shares of our capital stock that would result in the ownership or control of in excess of 23% of our outstanding capital stock by one or more persons who is not a U.S. citizen for purposes of U.S. coastwise shipping will be void and ineffective as against us. In addition, if at any time persons other than U.S. citizens own shares of our capital stock or possess voting power over any shares of our capital stock in excess of 23%, we may withhold payment of dividends, suspend the voting rights attributable to such shares, redeem such shares or require the non-citizens who most recently acquired shares to divest such excess shares to persons who are U.S. citizens in such manner as our board of directors directs. The required redemption price could be materially different from the current price of the common stock or the price at which the non-citizen acquired the common stock. If a non-citizen purchases the common stock, there can be no assurance that he will not be required to divest the shares and such divestiture could result in a material loss. These restrictions and redemption rights may have an adverse impact on the liquidity or market value of our common stock because holders may be unable to transfer our common stock to non-U.S. citizens. For more information on the above referenced restrictions and redemption rights, see “Description of Capital Stock — Restrictions on Ownership” in the accompanying prospectus.

USE OF PROCEEDS

We expect the net proceeds from this offering to be approximately $79,080,400 ($90,994,960 if the underwriters exercise their over-allotment option in full), after deducting the underwriting discount and our estimated expenses totaling approximately $350,000, based on a public offering price of $19.70 per share. We intend to use the net proceeds from this offering to repay approximately $30.0 million of outstanding borrowings under our existing credit facility, and to use the balance for capital expenditures, possible future acquisitions and general corporate purposes. Pending these uses, we intend to invest the net proceeds in short-term, investment-grade, interest-bearing securities.

As of June 30, 2009, our existing indebtedness consisted of borrowings of approximately $30.0 million in aggregate principal amount under our existing credit facility that is scheduled to mature in September 2010. As of June 30, 2009, the interest rate on our outstanding indebtedness under the credit facility was 1.81% with respect to approximately $12.4 million of outstanding borrowings and 1.93% with respect to approximately $17.6 million of outstanding borrowings. For additional information regarding our existing credit facility, please read “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Sources of Capital” in this prospectus supplement.

CAPITALIZATION

The following table sets forth our cash and capitalization as of June 30, 2009 on an actual basis and as adjusted to give effect to the sale of 4,200,000 shares of our common stock in this offering (based on a public offering price of $19.70 per share and our estimated net proceeds from that sale). You should read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this prospectus supplement and with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our historical financial statements and the notes to those financial statements in our 2008 Form 10-K and our Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 2009 and March 31, 2009, which are incorporated by reference in the accompanying prospectus.

TABLE OF CONTENTS

SELECTED CONSOLIDATED FINANCIAL DATA

The following table sets forth selected consolidated financial information for the periods represented. The selected consolidated financial data as of and for each of the three years in the period ended December 31, 2008 has been derived from our audited consolidated financial statements and notes thereto, which have been audited by Grant Thornton LLP, contained in our 2008 Form 10-K. The share and per share financial data presented below has been adjusted to give effect to the 2.23 for one reverse split of our common stock that we effected on May 17, 2007.

In October 2004, we were acquired by Orion Marine Group, Inc., formerly known as Hunter Acquisition Corp., a corporation formed and controlled by our former principal stockholders. For accounting purposes, our company as it existed until the time we were acquired by Hunter Acquisition Corp. is referred to as our “Predecessor” and our company as it has existed since the acquisition is referred to as our “Successor.” Concurrent with the acquisition and in accordance with GAAP, we wrote up the value of our assets to their current market value (as determined by appraisals for certain of our assets, such as equipment and land) at the time of the transaction. The result of this write up increased the book value of our assets and the associated depreciation expense. Therefore, depreciation expense for our Predecessor was less than depreciation expense for our Successor.

Historical results are not necessarily indicative of results we expect in future periods. The data presented below should be read in conjunction with, and are qualified in their entirety by reference to, “Capitalization” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this prospectus supplement, “Selected Financial Data” in our 2008 Form 10-K, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and the notes thereto included in our 2008 Form 10-K and in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2009 and June 30, 2009, which are incorporated by reference in the accompanying prospectus.

The following table includes the non-GAAP financial measure of EBITDA. For a definition of EBITDA and a reconciliation to net income calculated and presented in accordance with GAAP, please see “— Non-GAAP Financial Measures.”

Non-GAAP Financial Measures

We include in this prospectus supplement the non-GAAP financial measure of EBITDA. We define EBITDA as income before interest, income taxes, depreciation and amortization. EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements such as investors, commercial banks and others, to assess:

TABLE OF CONTENTS

EBITDA is not a presentation made in accordance with GAAP. EBITDA should not be considered an alternative to, or more meaningful than, net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP as measures of operating performance, liquidity or ability to service debt obligations. Because EBITDA excludes some, but not all, items that affect net income and is defined differently by different companies in our industry, our definition of EBITDA may not be comparable to similarly titled measures of other companies. EBITDA has important limitations as an analytical tool, and you should not consider it in isolation.

The following table provides a reconciliation of EBITDA to our net income for the periods indicated as calculated and presented in accordance with GAAP:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations provides a narrative analysis explaining the reasons for material changes in our (i) financial condition since the most recent fiscal year-end, and (ii) results of operations during the current fiscal year-to-date period and current fiscal quarter as compared to the corresponding periods of the preceding fiscal year. In order to better understand such changes, this Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our fiscal 2008 audited consolidated financial statements and notes thereto included in our 2008 Form 10-K, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Item 7 of our 2008 Form 10-K and with our unaudited financial statements and related notes appearing in our Quarterly Report on Form 10-Q for the period ended June 30, 2009, all of which are incorporated by reference in the accompanying prospectus.

Overview

We are a leading marine specialty contractor serving the heavy civil marine infrastructure market. We provide a broad range of marine construction and specialty services on, over and under the water along the Gulf Coast, the Atlantic Seaboard and the Caribbean Basin. Our customers are federal, state and municipal governments, the combination of which accounted for approximately 60% of our revenue in the three months ended June 30, 2009, as well as private commercial and industrial enterprises. We are headquartered in Houston, Texas.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation with private parties. Our bidding activity is affected by such factors as backlog, current utilization of equipment and other resources, ability to obtain necessary surety bonds and competitive considerations. The timing and location of awarded contracts may result in unpredictable fluctuations in the results of our operations.

Most of our revenue is derived from fixed-price contracts. There are a number of factors that can create variability in contract performance and therefore impact the results of our operations. The most significant of these include the following:

All of these factors can impose inefficiencies on contract performance, which can impact the timing of revenue recognition and contract profitability. We plan our operations and bidding activity with these factors in mind and they have not had a material adverse impact on the results of our operations in the past.

Recent Developments

On April 17, 2009, the U.S. Environmental Protection Agency (“EPA”) concluded that carbon dioxide and five other greenhouse gases are a danger to public health and welfare, thus providing a basis for EPA regulation and control of emissions of such gases. The EPA finding is subject to public comment before an official ruling is made. Further, on June 26, 2009, the House of Representatives passed a climate change bill to reduce United State greenhouse gas emissions.

As more fully discussed in our 2008 Form 10-K, passage of climate control legislation or adoption of regulations that restrict emissions of greenhouse gases could have an adverse effect on our operations and demand for our services. The Company will continue to monitor the impact of EPA’s actions, the House bill referenced above, and subsequent legislative actions on its business as more information as to the type and nature of potential regulation becomes available.

TABLE OF CONTENTS

In addition to its proposed rule regarding safety hazards related to the operation of hoisting equipment, such as cranes, discussed in more detail in our 2008 Form 10-K, the US Occupational Safety and Health Administration (“OSHA”) is expected to promulgate a rule which will impose stricter and more OSHA standards on certain of the Company’s marine operations, including standards on the control of hazardous energy, so-called “lock-out, tag-out” or LOTO standards (which proposal is printed in the Federal Register, 72 Federal Register 72452.) While the Company does not currently expect that OSHA’s final rule will materially, adversely impact its operations or financial condition, we are continuing to monitor potential impacts as OSHA’s promulgation of the rule progresses.

Outlook

Despite continued instability in the economy and the challenges facing many state and local budgets, to date, we have not seen a general, significant decline in our end market bidding activity. Indeed, supplemental emergency funding legislation signed into law in 2008 provides $740 million to the U.S. Army Corps of Engineers allocated for emergency dredging and construction projects in areas affected by the 2008 storms, which include the markets in which we operate. The $787 billion American Recovery and Reinvestment Act provides $90 billion of infrastructure spending, including $27.5 billion toward highway construction, $4.6 billion to the U.S. Army Corps of Engineers, and $240 million for U.S. Coast Guard bridge alterations and construction improvements. Recently, we have seen the pace of projects released for bid by the U.S. Army Corps of Engineers increase in the markets we serve.

In the short term, we have benefitted from the general decline in commodity prices, particularly in fixed cost or unit price contracts where we have been able to release certain cost contingencies. However, continued depressed commodity prices may adversely affect the revenue potential of future projects on which we choose to bid.

We continue to monitor our credit exposure. During the six months ended June 30, 2009, our operations provided cash from operations in excess of $23.7 million and our cash position at June 30, 2009 was in excess of $44.0 million. Our operations are not currently dependent on external short-term funding and we have not utilized the $7.6 million available to us under our revolving credit facility.

Our focus in 2009 is to concentrate on our core objectives; to manage our business effectively and efficiently in this unstable economic environment; to pursue rational growth strategies while closely monitoring the costs of our operations; and to maintain our strong balance sheet.

Business Drivers and Measures

Industry trends impact our results of operations. In operating our business and monitoring its performance, we also pay attention to a number of performance measures and operational factors.

Industry Trends

Our performance is impacted by overall spending in the heavy civil marine infrastructure market. Spending by our customers, both government and private, is impacted by several important trends affecting our industry, including the following:

TABLE OF CONTENTS

In the aggregate, these industry trends drive marine transportation facility construction, dredging, bridge building, repair and maintenance, as well as specialty services that we perform in our markets.

Bidding

Most of our contracts are obtained through competitive bidding on terms specified by the party inviting the bid. The nature of the contract specifications dictates the type of equipment, material and labor involved, all of which affect the cost of performing the contract and the price that our competitors will bid. Contracts for projects are generally awarded to the lowest qualified bidder, provided the bid is no greater than the amount of funds that are budgeted and available for the project. If all bids are greater than the available funds, then projects may be subject to rebid or cancellation as a result of budget constraints.

Utilization

An important factor that we take into consideration when we manage our business is the current and projected utilization of our equipment and personnel. We do not measure utilization of equipment or personnel in the aggregate, but rather track utilization by our major pieces of equipment, such as barges, cranes, dredges, tugs, etc., and the associated personnel required to operate the equipment.

Backlog

Once we have successfully bid on a project and executed a contract to perform the work, we record the value of the contract as backlog. Our backlog is the financial representation of the revenue associated with the future commitments of our equipment and personnel tracked in our project management software system. Backlog consists of projects that have either (a) not yet started, or (b) are in progress but are not yet complete. Consequently, backlog is also an important factor we use to monitor our business. The typical duration of our contracts is three to nine months, so our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve-month period.

As our business continues to grow, we expect that our backlog will increase over time. However, our backlog may fluctuate significantly from quarter to quarter, and a quarterly decrease of our backlog might not necessarily translate into a deterioration of our business. For example, in anticipation of bidding on a large project for which we believe we will be the successful bidder, we may choose not to bid on near-term projects so that our schedule can accommodate a large job. Even though this management decision would result in a near-term decline in our backlog, it is not inconsistent with our dual goals of maintaining high utilization rates of our equipment and personnel and long-term growth in our backlog.

Revenue

We recognize our revenue using the percentage-of-completion methodology. Percentage-of-completion for construction contracts is measured principally by the costs incurred and accrued to date for each contract to the estimated total costs for each contract at completion. We generally consider contracts substantially complete upon acceptance by the customer and departure from the construction site. A significant portion of our revenue depends on project funding by various government agencies and is adversely affected by decreased level of, or delays in, government funding.

Cost of Revenue

The components of costs of contract revenues include labor, equipment (including depreciation, insurance, fuel, maintenance and supplies), materials, lease expense and project overhead. Costs of contract revenues vary significantly depending on the type and location of work performed and assets utilized. Since the realization of our revenue is driven primarily by the cost of our revenues in relation to our estimated total costs to complete a contract, we monitor the costs realized to date and the estimated costs required to complete a project very closely, on a project-by-project basis, using our project management software system. By closely monitoring our jobs, we are able to quickly identify potential issues and respond accordingly. We believe that our ability to effectively manage the cost of revenue is a competitive strength of our organization and is indicative of the depth of our management team.

TABLE OF CONTENTS

Another important aspect of managing our cost of revenue is to recognize opportunities for change orders, which is a change to the original specifications of the contract, and occurs once a project has begun. In doing so, we are able to (a) recognize additional revenue from a project on a negotiated basis, rather than a competitive bidding situation, at generally higher margins, and (b) avoid potential disputes with our customers regarding required deviations from the original terms of the contract.

Selling, General and Administrative Expenses

Our selling, general and administrative costs include non-contract related salaries and expenses, incentive compensation, discretionary profit sharing and other variable compensation, as well as other overhead costs to support our overall business. In general, these costs will increase in response to our growth and the related increased complexity of our business.

Other Factors

Other factors that will influence our operations in future periods include the following:

Seasonality.  Substantially all of our services are performed on, over and under the water, causing our results to be subject to seasonal variations due to weather conditions. The core markets in which we operate — the Gulf Coast, the Atlantic Seaboard and the Caribbean Basin — are affected by hurricanes and tropical storms during hurricane season, which occurs annually in the Gulf of Mexico and Atlantic Ocean from June through November. Over 97% of the hurricanes and tropical storms occur during hurricane season, and 78% occur from August through October. Generally, wet conditions do not affect our operations, but major hurricanes and tropical storms may temporarily delay our operations, and we monitor all named storm systems to determine which projects, if any, will be affected. Because hurricanes and tropical storms move slowly, we usually have ample time to prepare appropriately for the storm, which typically includes demobilizing much of our equipment and removing our employees from the job site. Once the storm has passed, we must then mobilize our personnel and equipment back to the job site, which results in delays in the completion of our work and may result in an increase in the costs associated with performing our work.

Generally, in our fixed-price contracts we bear the risks of increased costs, delays to completion of work, damage to our equipment, and damage to the work already completed at a job site, related to severe weather conditions, such as hurricanes and tropical storms. Consequently, our cost estimates to complete a job in a hurricane prone area during hurricane season include costs related to mobilizing and demobilizing personnel and equipment, and our schedule assumes there will be delays associated with hurricanes and tropical storms. In 2008, seven named storms affected the Atlantic and Gulf coastal regions of the United States. At least one storm during this time affected all of our job sites, and several projects experienced delays due to the impact of as many as three storms, utilizing the contingencies in place and resulting in higher project costs than if we had not used the contingency. In years where the hurricane activity is less than expected or does not significantly impact our job sites, as was the case in 2006 and 2007, we are able to release certain contingencies within our jobs as they are completed.

Surety Bonding.  In connection with our business, we generally are required to provide various types of surety bonds that provide an additional measure of security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends upon our capitalization, working capital, past performance, management expertise and external factors, including the capacity of the overall surety market. Surety companies consider such factors in light of the amount of our backlog that we have currently bonded and their current underwriting standards, which may change from time-to-time. During the year ended December 31, 2008, approximately 38% of our projects, measured by revenue, required us to post a bond. The bonds we provide typically have face amounts ranging from $1.0 to $50.0 million. As of June 30, 2009, we had approximately $100.0 million in surety bonds outstanding and we believe our capacity under our current bonding arrangement was in excess of $400.0 million in aggregate surety bonds. We believe that our bonding capacity provides us with a significant competitive advantage relative to many of our local competitors, as many of these competitors are sole proprietors and are often required to personally guarantee their surety bonds, which frequently limits their bonding capacity.

Significant Changes in Ownership

2007 Private Placement.  In May 2007, we completed the sale of 20,949,216 shares of our common stock at a sale price of $13.50 per share to qualified institutional buyers, non-U.S. persons and accredited investors. In addition, we repurchased and retired all of our outstanding preferred stock and 16,053,816 shares of our common stock from our former principal stockholders using approximately $242.0 million of the net proceeds, which resulted in a net increase in shares outstanding of 4,895,400 shares.

The 2007 Private Placement is more fully described in Note 3 of the Notes to Consolidated Financial Statements contained in our 2008 Form 10-K, which is incorporated by reference into the accompanying prospectus.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Our significant accounting policies are described in more detail in Note 2 of the Notes to Consolidated Financial Statements contained in our 2008 Form 10-K, which is incorporated by reference into the accompanying prospectus. We believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition.  We enter into construction contracts principally on the basis of competitive bids. Although the terms of our contracts vary considerably, most are made on a fixed price basis. Revenues from construction contracts are recognized on the percentage-of-completion method in accordance with the AICPA Statement of Position 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts. The percentage-of-completion method measures the ratio of costs incurred and accrued to date for each contract to the estimated total costs for each contract at completion. This requires us to prepare on-going estimates of the costs to complete each contract as the project progresses. In preparing these estimates, we make significant judgments and assumptions concerning our significant cost drivers of materials, labor and equipment, and we evaluate contingencies based on possible schedule variances, production delays or other productivity factors.

Actual costs may vary from the costs we estimated. Variations from estimated contract costs along with other risks inherent in fixed price contracts may result in actual revenue and gross profits differing from those we estimated and could result in losses on projects. If a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined. We consider unapproved change orders to be contract variations on which we have customer approval for scope change, but not for price associated with that scope change. These costs are included in the estimated cost to complete the contracts and are expensed as incurred. We recognize revenue equal to cost incurred on unapproved changed orders when realization of price approval is probable and the estimated amount is equal to or greater than our cost related to the unapproved change order and the related margin when the change order is formally approved by the customer. Revenue recognized on unapproved change orders is included in contract costs and estimated earnings in excess of billings on uncompleted contracts on the balance sheet. We consider claims to be amounts that we seek or will seek to collect from customers or others for customer-caused changes in contract specifications or design, or other customer-related causes of unanticipated additional contract costs on which there is no agreement with customers on both scope and price changes. Revenue from claims is recognized when agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract. Costs associated with claims are included in the estimated costs to complete the contracts and are expensed when incurred. Depending on the size of a particular project, variations from estimated project costs could have a significant impact on our operating results for any fiscal quarter or year. We believe our exposure to losses on fixed price contracts is limited by the relatively short duration of the contracts we undertake and our management’s experience in estimating contract costs. We provide for contract losses in their entirety in the period they become known, without regard to the percentage of completion.

TABLE OF CONTENTS

Long-Lived Assets.  Fixed assets are carried at cost and are depreciated over their estimated useful lives, ranging from one to thirty years, using the straight-line method for financial reporting purposes and accelerated methods for tax reporting purposes. The carrying value of all long-lived assets is evaluated periodically in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, to determine if adjustment to the depreciation period or the carrying value is warranted. If events and circumstances indicate that the long-lived assets should be reviewed for possible impairment, we use projections to assess whether future cash flows on a non-discounted basis related to the tested assets are likely to exceed the recorded carrying amount of those assets to determine if write-down is appropriate. If we identify impairment, we will report a loss to the extent that the carrying value of the impaired assets exceeds their fair values as determined by valuation techniques appropriate in the circumstances that could include the use of similar projections on a discounted basis.

Goodwill.  We evaluate goodwill annually for potential impairment in accordance with SFAS No. 142, Goodwill and Other Intangible Assets, and more frequently if an event or circumstance indicates that impairment may have occurred. We perform our required annual impairment test for goodwill using a discounted cash flow analysis supported by comparative market multiples to determine the fair values of our reporting units versus their book values. When a possible impairment for a reporting unit is indicated, the implied fair value of goodwill is tested by comparing the carrying amount of net assets of the reporting unit excluding goodwill to the total fair value. When the carrying amount of goodwill exceeds its implied fair value, an impairment charge is recorded. Included in this evaluation are certain assumptions and estimates to determine fair value of reporting units such as estimates of future cash flows, discount rates as well as assumptions and estimates related to valuation of other identifiable intangible assets. Changes in these assumptions and estimates or significant changes to the market value of our company could materially impact our results of operations or financial position. As of June 30, 2009, goodwill was $12.1 million and no impairment loss was recorded during the period.

Income Taxes.  We account for income taxes in accordance with SFAS No. 109, “Accounting for Income Taxes,” and other applicable authoritative pronouncements. We evaluate valuation allowances for deferred tax assets for which future realization is uncertain. We perform this evaluation at least annually at the end of each fiscal year. The estimation of required valuation allowance includes estimates of future taxable income. In our assessment of our deferred tax assets at December 31, 2008, we considered that it was more likely than not that all of the deferred tax assets would be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment.

We account for uncertain tax positions in accordance with the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). The implementation of FIN 48 required us to make subjective assumptions and judgments regarding income tax exposure. Interpretations of and guidance surrounding income tax laws and regulations change over time, and these may change our subjective assumptions, which in turn, may affect amounts recognized in the condensed consolidated balance sheets and statements of income.

Insurance Matters, Litigation, Claims and Contingencies.  We maintain insurance coverage for our business and operations. Insurance related to property, equipment, automobile, general liability and a portion of workers’ compensation is provided through traditional policies, subject to a deductible. A portion of our workers’ compensation exposure is covered through a mutual association, which is subject to supplemental calls.

We have elected to retain a portion of losses that may occur through the use of various deductibles, limits and retentions under our insurance programs. In accordance with SFAS No. 5, “Accounting for Contingencies,” losses on these policies up to the deductible amounts are accrued in our Consolidated Balance Sheets based on known claims incurred and an estimate of claims incurred but not yet reported. We derive our accruals from actuarial studies, known facts, historical trends and industry averages utilizing the assistance of an actuary to determine the best estimate of the ultimate expected loss. Actual claims may vary from our estimate. We include any adjustments to such reserves in our consolidated results of operations.

TABLE OF CONTENTS

Accounting for Stock Issued to Employees and Others.  We account for equity awards issued to employees and others under the provisions of SFAS No. 123(R), Share-Based Payment. Among its provisions, SFAS No. 123(R) requires us to recognize compensation expense for equity awards over the vesting period based on the fair value of these awards at the date of grant. We use the Black-Scholes option-pricing model to compute the fair value of option awards on the date of grant. The Black-Scholes model requires the use of highly subjective assumptions in the computation. Changes in these assumptions can cause significant fluctuations in the fair value assigned to the option award. The fair value of restricted stock grants is equivalent to the fair value of the stock issued on the date of grant.

Contract Revenues.  Revenues for the six months ended June 30, 2009 increased approximately 17.7% as compared with the same period last year. The increase, as compared with last year, was attributable, in part, to our expansion late in the first quarter of 2008 of our dredging and other construction capabilities along the Atlantic Seaboard. Contract revenue generated from government agencies, including federal, state and local municipalities represented 56% of total revenues in the first six months of 2009, with projects in the private sector comprising 44% of revenue, as compared with the six months of 2008, when the mix of customers included 51% from government agencies and 49% from the private sector.

Gross Profit.  Gross profit increased approximately $13.2 million, or 66.6%, in the first half of 2009 as compared with the corresponding period last year. The improvement in gross profit was due to the increase in revenues, as well as our ability to release certain cost contingencies, resulting from improved project execution and performance. Gross margin for the six months ended June 30, 2009 was 23.5%, as compared with 16.6% in the prior year period. Additionally, in the prior year unforeseen site conditions on two dredging projects resulted in project delays and adversely affected gross profit and margins. We self-performed approximately 93% of our work in the current year period, a significant increase over the first six months of 2008, when our self-performance rate was 87% of total costs. Increased self-performance generally results in an increase in margins.

Selling, General and Administrative Expense.  Selling, general and administrative (“SGA”) expenses increased $4.4 million in the six months ended June 30, 2009 as compared with the prior year period. The increase in expense was due to overheads and amortization of intangible assets related to the acquisition of the assets of Subaqueous Services, Inc. (“SSI”) in February 2008, and to an increase in our reserve for doubtful accounts. In the six months ended June 30, 2008, we recovered in full a previously reserved receivable and benefitted from lower group medical and workers’ compensation expenses.

TABLE OF CONTENTS

Income Tax Expense.  Our effective rate for the six months ended June 30, 2009 was 37.4% and differed from our statutory rate of 35% primarily due to state income taxes and to other permanent differences in the current year. In the first quarter of 2008, we revised our estimate of the impact of certain permanent deductions available to us on our federal tax return, which reduced our effective rate for the six-month period to 35.7%.

Year Ended December 31, 2008 Compared With Year Ended December 31, 2007

The following information is derived from our historical results of operations:

Net income		$	14,475				5.6	%		$	17,399				8.3	%

Contract Revenues.  Total revenue increased $51.4 million, or 24.5%, from $210.4 million for the year ended December 31, 2007 to $261.8 million for the year ended December 31, 2008. The increase in revenue was due to geographic expansion of our dredging capabilities along the eastern coast of the United States and to the progress schedules and rate of completion of the contracts in progress in 2008, despite an active hurricane season in the year with seven named storms that affected our entire operations at various times. Revenues generated by the private sector increased by a substantial 45% in 2008 as compared with 2007. However, revenues generated from federal agencies decreased by 22.4% in 2008 as compared with 2007 due to a slow volume of bid opportunities by the Corps of Engineers.

Gross Profit.  Gross profit was comparable to the prior year, however, gross margin decreased from 24.0% in 2007 to 19.3% in 2008. The downward pressure on margin was due primarily to the use of outside subcontractors resulting from the scope of work in the mix of contracts in progress during 2008, which reduced our self-performance rate (as measured by cost) from 90.3% in 2007 to 88.2% in 2008. Significant production delays which resulted from unexpected amounts of trash and unforeseen site conditions on two projects involving dredging services, negatively affected gross margins. In addition, we achieved higher margins on certain projects in 2007, due to productivity gains on labor and other factors.

Selling, General and Administrative Expense.  As compared with the prior year, SGA expenses increased $5.0 million or 21.9% in 2008. Current year expenses include amortization related to intangible assets; additional overheads to support the business growth we experienced in 2008; and a full complement of annual public company expenses. In addition, we increased our bad debt reserve to $0.8 million, related to receivables on two projects, and our property taxes increased as compared with 2007, due in part to property taxes related to our geographic expansion. In the prior year, we incurred one-time payments of bonuses and incentives to key employees upon the successful consummation of the common stock offering in May 2007, which totaled approximately $2.6 million. As a percentage of revenues, however, SGA expenses decreased slightly, from 10.9% of revenues to 10.5%, reflecting our continued focus on the management of costs.

Interest Expense, Net of Interest Income.  The increase in interest expense in 2008 directly resulted from debt incurred to purchase the assets of SSI in February 2008. In 2007, upon closing of the private placement transaction, we repaid all debt outstanding at that time. We earn interest income on the cash balances we maintain throughout the year.

TABLE OF CONTENTS

Income Tax Expense.  Our effective tax rate of 33.5% differed from our statutory rate of 35%, primarily due to the benefit of the domestic production activities deduction on our tax return and true-ups of federal and state deferred taxes. Excluding these true-ups, which should not reoccur, our effective tax rate was 36.4% and differed from the statutory rate due to our estimate of the impact of certain permanent deductions available on our federal tax return, offset by increases in state income taxes. The effective rate of 36.9% in 2007 differed from the statutory rate primarily due to permanent non-deductible differences and to state income taxes.

Liquidity and Capital Resources

Our primary liquidity needs are to finance our working capital, invest in capital expenditures, and pursue strategic acquisitions. Historically, our source of liquidity has been cash provided by our operating activities and borrowings under our credit facility.

Our working capital position fluctuates from period to period due to normal increases and decreases in operational activity. At June 30, 2009, our working capital was $64.8 million compared to $47.0 million at December 31, 2008. The increase of $17.8 million in working capital was primarily due to an improved cash position and decreases in trade payables and liabilities related to billings in excess of costs and estimated earnings on uncompleted contracts. As of June 30, 2009, we had cash on hand and availability under our revolving credit facility of $51.6 million.

We continue to monitor our credit exposure. At June 30, 2009, our operations provided cash from operations in excess of $23.7 million and our cash position was in excess of $44.0 million. Our operations are not currently dependent on external short-term funding, and we have not utilized our available borrowing of $7.6 million under our revolving credit facility.

We expect to meet our future internal liquidity and working capital needs, service our debt, and maintain our equipment fleet through capital expenditure purchases and major repairs, from funds generated in our operating activities for at least the next 12 months. We believe our cash position, combined with the capacity available under our revolving credit facility, is adequate for our general business requirements.

The following table provides information regarding our cash flows and capital expenditures for the six months ended June 30, 2009 and 2008 (unaudited):

		Six Months Ended June 30,
		2009				2008
		(In Thousands)
Cash flows provided by operating activities		$	23,667			$	12,180
Cash flows used in investing activities		$	(4,302	)		$	(45,184	)
Cash flows provided by (used in) financing activities		$	(1,074	)		$	34,920

Operating Activities.  During the six months ended June 30, 2009, our operating activities provided $23.7 million of cash as compared with $12.2 million for the six months ended June 30, 2008. Contributing to the increase between comparable periods was an increase of $5.8 million within working capital components, including strong collections of receivables during the period and a decrease in vendor payables related to the timing of such payments, and to the nature of the contracts in progress. In addition, we had increases in non-cash items affecting net income, such as depreciation and amortization expense associated with the equipment and intangible assets acquired from SSI, and an increase in non-cash stock-based compensation related to grants of options during 2008.

Investing Activities.  Our capital asset additions totaled $4.7 million in the six months ended June 30, 2009, as compared with $8.6 million in the prior year period. In February 2008, we purchased substantially all of the assets of SSI for a total purchase price of $35 million, plus $1.7 million related to the acquisition of projects under contract by SSI, for total cash related to the acquisition of $36.7 million.

Financing Activities.  In the six months ended June 30, 2009, we paid down our principal balances on our credit facility, which was offset by proceeds received from stock option exercises, including the related excess tax benefits. Cash provided by financing activities in the prior year period was attributable to our borrowing of $35 million under of line of credit to fund the assets purchased from SSI.

TABLE OF CONTENTS

Sources of Capital

In addition to our cash balances and cash provided by operations, we have a credit facility available to us to finance capital expenditures and working capital needs.

We have a credit agreement with several participating banks. In February 2008, we borrowed $35 million to fund the purchase of the assets of SSI, and amended our credit facility to reflect the borrowing. After such borrowing, we have available up to $15 million under an acquisition term loan facility and up to $8.5 million under a revolving line of credit.

The revolving line of credit is subject to a borrowing base and availability on the revolving line of credit is reduced by any outstanding letters of credit. At June 30, 2009, we had outstanding letters of credit of $910,000, thus reducing the balance available to us on the revolving line of credit to approximately $7.6 million. We are subject to a monthly commitment fee on the unused portion of the revolving line of credit at a current rate of 0.20% of the unused balance. As of June 30, 2009, no amounts had been drawn under the revolving line of credit.

Payments of interest are due monthly. Payments of principal are due quarterly in seven equal installments of $875,000, plus an annual principal payment based on year end results. The additional principal payment of $2.4 million, based on the 2008 year end results was paid on April 30, 2009. All provisions under the credit facility mature on September 30, 2010.

Interest on our borrowings is based on the prime rate, less an applicable margin, or on the LIBOR rate, plus an applicable margin, then in effect, at our discretion. For each prime rate loan drawn under the credit facility, interest is due quarterly at the then prime rate minus a margin that is adjusted quarterly based on total leverage ratios, as applicable. For each LIBOR loan, interest is due at the end of each interest period at a rate of the then LIBOR rate for such period plus the LIBOR margin based on total leverage ratios, as applicable. At June 30, 2009, interest was based on LIBOR. The LIBOR interest rate, plus the applicable margin, at June 30, 2009 was in two tranches, with rates of 1.81% and 1.93%.

The credit facility is secured by the bank accounts, accounts receivable, inventory, equipment and other assets of our company and our subsidiaries and places restrictions on us as to our ability to incur additional debt, pay dividends, advance loans, and engage in other actions. The credit facility also requires us to maintain certain financial ratios as follows:

At June 30, 2009, we were in compliance with all our financial covenants with a sufficient margin as to not impair our ability to incur additional debt or violate the terms of our credit facility. Historically, we have not relied on debt financing to fund our operations or working capital.

Bonding Capacity

We are generally required to provide various types of surety bonds that provide additional security to our customers for our performance under certain government and private sector contracts. Our ability to obtain surety bonds depends on our capitalization, working capital, past performance and external factors, including the capacity of the overall surety market. At June 30, 2009, we believe our capacity under our current bonding arrangement was in excess of $400 million, of which we had approximately $100 million in surety bonds outstanding. Despite the prevailing economic conditions, we believe our strong balance sheet and working capital position will allow us to continue to access our bonding capacity. During the quarter ended June 30, 2009, approximately 60% of projects, measured by revenue, required us to post a bond.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES FOR NON-U.S. HOLDERS

The following general discussion summarizes the material U.S. federal income tax consequences relating to the purchase, ownership and disposition of our common stock by a non-U.S. holder (as defined below). Except where noted, this summary deals only with common stock that is held as a “capital asset” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended to the date hereof (the “Code”) (generally, property held for investment).

A “non-U.S. holder”, for purposes of this section, means a beneficial owner of common stock (other than a partnership or entity treated as a partnership for U.S. federal income tax purposes) that is not for U.S. federal income tax purposes any of the following:

This summary is based upon provisions of the Code, administrative pronouncements, final, temporary and proposed Treasury Regulations, administrative rulings and judicial decisions, all as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below. In addition, provisions of applicable tax treaties may supersede the general rules set forth in this summary. This summary does not address all aspects of U.S. federal income tax and does not deal with U.S. estate tax or gift tax or foreign, state, local or other tax considerations that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws such as (without limitation):

If a partnership (including an entity treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership (including an entity treated as a partnership for U.S. federal income tax purposes) holding our common stock, you should consult your tax advisor.

TABLE OF CONTENTS

We have not sought any ruling from the Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions. If you are considering buying our common stock, we urge you to consult your tax advisor about the particular federal, state, local and foreign tax consequences of the purchase, ownership and disposition of our common stock, and the application of the U.S. federal income tax laws to your particular situation.

Dividends

Any distributions on our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of earnings and profits will constitute a return of capital that is applied against and reduces the non-U.S. holder’s adjusted tax basis in our common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of our common stock and will be treated as described under “Gain on Disposition of Common Stock” below. Any dividend paid to a non-U.S. holder of our common stock ordinarily will be subject to withholding of U.S. federal income tax at a rate of 30%, or such lower rate as may be specified under an applicable income tax treaty, unless the dividend is effectively connected with a trade or business carried on by the non-U.S. holder within the United States. In order to receive a reduced treaty rate, a non-U.S. holder must provide us with IRS Form W-8BEN (or applicable substitute or successor form) properly certifying eligibility for the reduced rate.

Dividends paid to a non-U.S. holder that are effectively connected with the conduct of a trade or business by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base in the United States) generally will be exempt from the withholding tax described above and instead will be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates in the same manner as if the non-U.S. holder were a U.S. person as defined under the Code. In such cases, we will not have to withhold U.S. federal income tax if the non-U.S. holder complies with applicable certification and disclosure requirements. In order to obtain this exemption from withholding tax, a non-U.S. holder must provide us with an IRS Form W-8ECI (or applicable substitute or successor form) properly certifying eligibility for such exemption. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a rate of 30% or such lower rate as may be specified by an applicable tax treaty.

Gain on Disposition of Common Stock

Any gain realized on the disposition of our common stock by a non-U.S. holder generally will not be subject to U.S. federal income tax unless:

An individual non-U.S. holder who has gain that is described in the first bullet point immediately above will be subject to tax on the net gain derived from the disposition under regular graduated U.S. federal income tax rates. If a non-U.S. holder that is a foreign corporation has gain described under the first bullet point immediately above, it generally will be subject to tax on its net gain in the same manner as if it were a U.S. person as defined under the Code, and, in addition, may be subject to the branch profits tax equal to 30% of its effectively connected earnings and profits or at such lower rate as may be specified by an applicable income tax treaty.

TABLE OF CONTENTS

An individual non-U.S. holder who meets the requirements described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the disposition, which may be offset by U.S. source capital losses, even though the individual is not considered a resident of the United States.

Generally, a corporation is a U.S. real property holding corporation if the fair market value of its U.S. real property interests (as defined in the Code and applicable Treasury Regulations) equals or exceeds 50% of the aggregate fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. We have not determined whether we are a U.S. real property holding corporation for U.S. federal income tax purposes, and there can be no assurances we are not, or will not become, a U.S. real property holding corporation. If we are or become a U.S. real property holding corporation, so long as our common stock continues to be regularly traded on an established securities market, a non-U.S. holder will not be subject to U.S. federal income tax on the disposition of the common stock if it holds and has held (at all times during the shorter of the five-year period immediately preceding the date of disposition or the holder’s holding period) not more than 5% of the total outstanding shares of our common stock.

Non-U.S. holders should consult their own tax advisors with respect to the application of the foregoing rules to their ownership and disposition of our common stock.

Information Reporting and Backup Withholding

Payment of dividends and the tax withheld with respect thereto, is subject to information reporting requirements. These information reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable income tax treaty or withholding was not required because the dividends were effectively connected with a trade or business in the United States conducted by the non-U.S. holder. Copies of the information returns reporting such dividends and withholding may also be made available under the provisions of an applicable income tax treaty or agreement to the tax authorities in the country in which the non-U.S. holder resides. U.S. backup withholding will generally apply on payments of dividends to non-U.S. holders unless such non-U.S. holders furnish to the payor a Form W-8BEN (or other applicable form), or otherwise establish an exemption.

Payment by a U.S. office of a broker of the proceeds of a sale of common stock is generally subject to both backup withholding and information reporting unless the non-U.S. holder, or beneficial owner thereof, as applicable, certifies that it is a non-U.S. holder on Form W-8BEN (or other applicable form), or otherwise establishes an exemption. Subject to exceptions, backup withholding and information reporting generally will not apply to a payment of proceeds from the sale of common stock if such sale is effected through a foreign office of a broker.

Any amount withheld under the backup withholding rules from a payment to a non-U.S. holder is allowable as a credit against such non-U.S. holder’s U.S. federal income tax, which may entitle the non-U.S. holder to a refund, provided that the non-U.S. holder timely provides the required information to the IRS. Moreover, certain penalties may be imposed by the IRS on a non-U.S. holder who is required to furnish information but does not do so in the proper manner. Non-U.S. holders are urged to consult their own tax advisors regarding the application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury Regulations.

UNDERWRITING

FBR Capital Markets & Co. and Stephens Inc. are acting as representatives of the underwriters named below. Subject to the terms and conditions in the underwriting agreement, each underwriter named below has agreed to purchase from us, on a firm commitment basis, the respective number of shares of common stock shown opposite its name:

Underwriters		Number of Shares of Common Stock

Stephens Inc.			2,100,000
Total			4,200,000

The underwriting agreement provides that the underwriters’ obligations to purchase our common stock are subject to approval of legal matters by counsel and the satisfaction of other conditions. These conditions include, among others, the continued accuracy of representations and warranties made by us in the underwriting agreement, delivery of legal opinions, and the absence of material adverse changes in our assets or business after the date of this prospectus. The underwriters are obligated to purchase all of our shares in this offering, other than those covered by the over-allotment option described below, if they purchase any of our shares.

The representatives of the underwriters have advised us that the underwriters propose to offer the common stock directly to the public at the initial price to the public listed on the cover page of this prospectus supplement and to selected dealers, who may include the underwriters, at the initial price to the public less a selling concession not in excess of $0.47 per share for the common stock. The underwriters may allow, and the selected dealers may reallow, a concession not in excess of $0.10 per share for the common stock to brokers and dealers. After the completion of the offering, the underwriters may change the offering price and other selling terms.

The following table summarizes the underwriting discounts that we will pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares of common stock.

						Total

Price to the public		$	19.700			$	82,740,000			$	95,151,000
Underwriting discount paid by us		$	0.788			$	3,309,600			$	3,806,040

We have also agreed to reimburse the underwriters for all reasonable out-of-pocket expenses incurred in connection with this offering. We estimate that the total expenses of the offering, including registration, filing and listing fees, printing fees, blue sky fees and legal, accounting and transfer agent expenses, but excluding the underwriting discount, will be approximately $350,000.

In compliance with guidelines of the Financial Industry Regulatory Authority (FINRA), the maximum compensation or discount to be received by any participating FINRA members or independent broker dealers in connection with the offer and sale of any securities will not be greater than 8% of the aggregate amount of the securities offered pursuant to this prospectus supplement and the accompanying prospectus.

consequences of ownership of our common stock, or any securities convertible into, or exercisable or exchangeable for our common stock, whether or not such transaction would be settled by delivery of common stock or other securities, in cash or otherwise, without, in each case, the prior written consent of FBR Capital Markets & Co., subject to certain specified exceptions.

The 90-day restricted period described above is subject to extension under limited circumstances. In the event either (a) during the last 17 days of the applicable restricted period, we issue an earnings results or material news or a material event relating to us occurs; or (b) before the expiration of the applicable restricted period, we announce that we will release earnings results during the 16-day period following the last day of the applicable period, the “lock up” restrictions described above will, subject to limited exceptions, continue to apply until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of material news or a material event.

We have granted to the underwriters an option to purchase up to an aggregate of 630,000 shares of common stock, exercisable solely to cover over-allotments, if any, at the initial price to the public less the underwriting discounts shown on the cover page of this prospectus supplement. The underwriters may exercise this option in whole or in part at any time until 30 days after the date of the underwriting agreement. To the extent the underwriters exercise this option, each underwriter will be committed, so long as the conditions of the underwriting agreement are satisfied, to purchase a number of additional shares proportionate to that underwriter’s initial commitment as indicated in the table at the beginning of this section.

We have agreed to indemnify the underwriters against liabilities relating to the offering, including liabilities under the Securities Act and liabilities arising from breaches of the representations and warranties contained in the underwriting agreement, and to contribute to payments that the underwriters may be required to make for these liabilities.

The representative of the underwriters may engage in over-allotment transactions, stabilizing transactions, syndicate covering transactions, penalty bids and passive market making or purchases for the purpose of pegging, fixing or maintaining the price of our common stock in accordance with Regulation M under the Exchange Act.

TABLE OF CONTENTS

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representative of the underwriters will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

A prospectus supplement and an accompanying prospectus in electronic format will be made available on the Internet sites or through other online services maintained by one or more of the underwriters and/or selling group members participating in this offering, or by their affiliates.

The underwriters may agree with us to allocate specific number of shares for sale to online brokerage account holders. Any such allocations for online distributions will be made by the representative on the same basis as other allocations.

Other than the prospectus supplement and an accompanying prospectus in electronic format, the information on any underwriter’s or selling group member’s website and any information contained in any other website maintained by an underwriter or selling group member is not part of the prospectus supplement and an accompanying prospectus or the registration statement of which this prospectus supplement and an accompanying prospectus forms a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

The actual application of proceeds from the sale of any particular tranche of securities issued hereunder will be described in the applicable prospectus supplement relating to such tranche of securities. We may invest funds not required immediately for these purposes in marketable securities and short term investments. The precise amount and timing of the application of these proceeds will be dependent upon our funding requirements and the availability and cost of other funds.

DESCRIPTION OF CAPITAL STOCK

The following description of the material terms of our capital stock is only a summary of the information contained in our amended and restated certificate of incorporation. You should read this description together with our amended and restated certificate of incorporation and bylaws. Selected provisions of our organizational documents are summarized below. We have filed copies of our organizational documents with the SEC as exhibits to the registration statement of which this prospectus forms a part. See “Where You Can Find More Information” above for information on how to obtain copies of them.

General

Pursuant to our amended and restated certificate of incorporation, which we refer to as our certificate of incorporation, we have the authority to issue an aggregate of 60,000,000 shares of capital stock, consisting of 50,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock

As of June 30, 2009, we have a total of 21,928,741 shares of common stock outstanding, which does not include 11,646 shares held as treasury shares or shares reserved for issuance pursuant to our stock incentive plans, including outstanding options to purchase 975,300 shares and 630,336 shares available for future awards.

Voting Rights.  Each share of common stock is entitled to one vote in the election of directors and on all other matters submitted to a stockholder vote. Our stockholders may not cumulate their votes in the election of directors or any other matter.

Dividends.  Any dividends declared by our board of directors on our common stock will be payable ratably out of assets legally available therefor after payment of dividends required to be paid on shares of preferred stock, if any.

Liquidation.  In the event of any dissolution, liquidation or winding up of our affairs, whether voluntary or involuntary, after payment of our debts and other liabilities and making provision for any holders of our preferred stock who have a liquidation preference, our remaining assets will be distributed ratably among the holders of common stock.

Fully Paid.  All of the shares of common stock to be outstanding upon completion of this offering will be fully paid and nonassessable, which means that its holders will have paid their purchase price in full and we may not require them to pay additional funds.

Other Rights.  Holders of our common stock have no redemption or conversion rights and no preemptive or other rights to subscribe for our securities.

TABLE OF CONTENTS

Preferred Stock

Our board of directors has the authority to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rates, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of that series, which may be superior to those of the common stock, without further vote or action by the stockholders. There are currently no shares of preferred stock outstanding.

The issuance of shares of the preferred stock by our board of directors as described above may adversely affect the rights of the holders of common stock. For example, preferred stock issued by us may rank prior to the common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights, and may be convertible into shares of common stock.

When we issue preferred stock, we will provide specific information about the particular class or series being offered in a prospectus supplement. This information will include some or all of the following:

Upon issuance, the shares of preferred stock will be fully paid and nonassessable.

Liability and Indemnification of Officers, Directors and Certain Affiliates

Our certificate of incorporation contains certain provisions permitted under the Delaware General Corporation Law relating to the liability of directors. These provisions eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except that a director will be personally liable under the Delaware General Corporation Law:

TABLE OF CONTENTS

If the Delaware General Corporation Law is amended to authorize the further elimination or limitation of director’s liability, then the liability of our directors will automatically be limited to the fullest extent provided by law. These provisions do not limit or eliminate our rights or those of any stockholder to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s fiduciary duty. These provisions will not alter a director’s liability under federal securities laws.

Our certificate of incorporation and bylaws also provide that we must indemnify our directors and officers to the fullest extent permitted by Delaware law and also provide that we must advance expenses, as incurred, to our directors and officers in connection with a legal proceeding to the fullest extent permitted by Delaware law, subject to very limited exceptions. We may also indemnify employees and others and advance expenses to them in connection with legal proceedings.

We have entered into separate indemnification agreements with our directors and certain officers that provide our directors and such officers and any partnership, corporation, trust or other entity of which such director or officer is or was a partner, stockholder, trustee, director, officer, employee or agent (“Indemnitees”), with additional indemnification and related rights, particularly with respect to indemnification procedures and directors’ and officers’ insurance coverage. The indemnification agreements require us, among other things, to indemnify the Indemnitees, to the fullest extent permitted under applicable law, against liabilities that may arise by reason of the directors’ or officers’ acts or omissions while providing service to us, other than liabilities arising from acts or omissions:

An Indemnitee will be entitled to receive advance amounts for expenses such Indemnitee incurs in connection with claims or actions against such Indemnitee unless a court having jurisdiction over the claim makes a final judicial determination that such Indemnitee is prohibited from receiving indemnification. Furthermore, we are not responsible for indemnifying an Indemnitee if an independent reviewing party (a party not involved in the pending claim) determines that such Indemnitee is not entitled to indemnification under applicable law, unless a court of competent jurisdiction determines that such Indemnitee is entitled to indemnification. We believe that these indemnification arrangements are important to our ability to attract and retain qualified individuals to serve as directors.

We obtained directors’ and officers’ liability insurance to provide our directors and officers with insurance coverage for losses arising from claims based on any breaches of duty, negligence, or other wrongful acts, including violations of securities laws, unless such a violation is based on any deliberate fraudulent act or omission or any willful violation of any statute or regulation.

These provisions may have the practical effect in certain cases of eliminating the ability of our stockholders to collect monetary damages from our directors and officers. We believe that these provisions and agreements are necessary to attract and retain qualified persons as directors and officers.

Anti-Takeover Effects of Provisions of Delaware Law, Our Certificate of Incorporation and Bylaws

Our certificate of incorporation, bylaws and the Delaware General Corporation Law contain certain provisions that could discourage potential takeover attempts and make it more difficult for our stockholders to change management or receive a premium for their shares.

Delaware Anti-Takeover Statute.  We have elected to be subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, this section prevents certain Delaware companies under certain circumstances from engaging in a “business combination” with:

A “business combination” includes a merger or sale of 10% or more of our assets.

Charter and Bylaw Provisions

Classified Board.  Our certificate of incorporation provides that our board of directors is divided into three classes of directors, with the classes to be as nearly equal in number as possible. As a result, approximately one-third of our board of directors will be elected each year. The classification of directors has the effect of making it more difficult for stockholders to change the composition of our board of directors. Our certificate of incorporation and bylaws provide that the number of directors will be fixed from time-to-time exclusively pursuant to a resolution adopted by the board of directors.

Authorized But Unissued Shares.  The authorized but unissued shares of our common stock and preferred stock are available for future issues without stockholder approval. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy context, tender offer, merger or otherwise. Undesignated preferred stock may also be used in connection with a stockholder rights plan, although we have no present intention to adopt such a plan.

Filling Board of Directors Vacancies; Removal.  Our certificate of incorporation provides that vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by the affirmative vote of a majority of the directors then in office, though less than a quorum, or by the sole remaining director. Each director will hold office until his or her successor is elected and qualified, or until the director’s earlier death, resignation, retirement or removal from office. Any director may resign at any time upon written notice to our board of directors or to our President. Directors may be removed only for cause upon the affirmative vote of the holders of 75% of the voting power of the outstanding shares of capital stock voting together as a single class. We believe that the removal of directors by the stockholders only for cause, together with the classification of the board of directors, will promote continuity and stability in our management and policies and that this continuity and stability will facilitate long-range planning.

No Cumulative Voting.  The Delaware General Corporation Law provides that stockholders are not entitled to the right to cumulate votes in the election of directors or any other matter brought to a vote of our stockholders unless our certificate of incorporation provides otherwise. Under cumulative voting, a majority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors. Our certificate of incorporation does not provide for cumulative voting.

Election of Directors. Our bylaws require the affirmative vote of a plurality of the outstanding shares of our capital stock entitled to vote generally in the election of directors cast at a meeting of our stockholders called for such purpose.

Advance Notice Requirement for Stockholder Proposals and Director Nominations.  Our bylaws provide that stockholders seeking to bring business before or to nominate candidates for election as directors at a meeting of stockholders must provide timely notice of their proposal in writing to the corporate secretary.

TABLE OF CONTENTS

With respect to the nomination of directors, to be timely, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices:

whichever first occurs. With respect to other business to be brought before an annual meeting of stockholders, to be timely, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices not less than 120 days prior to the anniversary date of the proxy statement for the immediately preceding annual meeting of the stockholders. Our bylaws limit the business that may be brought before a special meeting of stockholders to the purposes stated in the notice for such meeting. Our bylaws also specify requirements as to the form and content of a stockholder’s notice. These provisions may preclude stockholders from bringing matters before a meeting of stockholders or from making nominations for directors at an annual meeting of stockholders or may discourage or defer a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of us.

Amendments to Our Certificate of Incorporation and Bylaws.  Pursuant to the Delaware General Corporation Law and our certificate of incorporation, certain anti-takeover provisions of our certificate of incorporation may not be repealed or amended, in whole or in part, without the approval of at least 80% of the outstanding stock entitled to vote. Our certificate of incorporation permits our board of directors to adopt, amend and repeal our bylaws. Our certificate of incorporation also provides that our bylaws can be amended by the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares of our common stock.

No Stockholder Action by Written Consent; Special Meeting.  Our certificate of incorporation precludes stockholders from initiating or effecting any action by written consent and thereby taking actions opposed by our board of directors in that manner. Our bylaws also provide that special meeting of stockholders may be called only by our board of directors.

Restrictions on Ownership

Restrictions on Foreign Ownership.  Certain U.S. maritime laws, including the Dredging Act, the Jones Act, the Shipping Act and the Vessel Documentation Act, prohibit foreign ownership or control of persons engaged in the transport of merchandise or passengers or dredging in the navigable waters of the U.S. A corporation is considered to be foreign owned or controlled if, among other things, 25% or more of the ownership or voting interests with respect to its equity stock is held by non-U.S. citizens. If we should fail to comply with such requirements, our vessels would lose their eligibility to engage in coastwise trade or dredging within U.S. domestic waters. To facilitate our compliance, our certificate of incorporation includes the following provisions:

TABLE OF CONTENTS

You may be required to certify whether you are a U.S. citizen before purchasing or transferring our common stock. If you or a proposed transferee cannot make such certification, or a sale of stock to you or a transfer of your stock would result in the ownership by non-U.S. citizens of 23% or more of our common stock, you may not be allowed to purchase or transfer our common stock. All certificates representing the shares of our common stock will bear legends referring to the foregoing restrictions.

In addition, our certificate of incorporation permits us to establish and maintain a dual stock certificate system under which different forms of certificates may be used to reflect whether the owner is a U.S. citizen.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “ORN.”

Transfer Agent and Registrar

Our transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase common stock, preferred stock, or debt securities. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will specify the following terms of any warrants in respect of which this prospectus is being delivered:

Warrants will be issued in registered form only and offered and exercisable in U.S. dollars. At the close of business on the expiration date, unexercised warrants will become void.

We have not issued any warrants to date.

DESCRIPTION OF RIGHTS

We may issue rights to purchase our securities. The rights may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. Each series of rights will be issued under a separate rights agent agreement to be entered into between us and one or more banks, trust companies or other financial institutions, as rights agent that we will name in the applicable prospectus supplement. The rights agent will act solely as our agent in connection with the rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights.

The prospectus supplement relating to any rights that we offer will include specific terms relating to the offering, including, among other matters:

TABLE OF CONTENTS

Each right would entitle the holder of the rights to purchase for cash the principal amount of securities at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will become void.

If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than our security holders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

TABLE OF CONTENTS

DESCRIPTION OF DEBT SECURITIES

Please note that in this section entitled “Description of Debt Securities,” references to “we,” “our” and “us” refer to Orion Marine Group, Inc. as the issuer of the applicable series of debt securities and not to any subsidiaries unless the context requires otherwise. In addition, references in this section to the “subsidiary guarantors” refer to certain of our subsidiaries that may guarantee the due and punctual payment of one or more series of our debt securities. Also, in this section, references to “holders” mean those who own debt securities registered in their own names on the books that we or the trustee maintain for this purpose and not those who own beneficial interests in debt securities registered in street name or in debt securities issued in book-entry form through one or more depositaries. Owners of beneficial interests in the debt securities should read the section below entitled “Legal Ownership and Book-Entry Issuance.”

Debt Securities May Be Senior or Subordinated

We may issue senior or subordinated debt securities. Neither the senior debt securities nor the subordinated debt securities will be secured by any property or assets of ours or any of our subsidiaries. Thus, by owning a debt security, you are an unsecured creditor of Orion Marine Group, Inc.

No stockholder, officer, director or employee of Orion Marine Group, Inc. has any obligation for payment of debt securities or for any of our obligations, covenants or agreements contained in the debt securities or the applicable indenture. By accepting the debt securities, you waive and release all liability of this kind. The waiver and release are part of the consideration for the issuance of debt securities. This waiver and release will not apply to the liability of the subsidiary guarantors solely in their capacity of guarantors of any series of our debt securities and solely to the extent of any such guarantee.

Our senior debt securities will be issued under the senior debt indenture, as described below, and will rank equally with all of our other senior unsecured and unsubordinated debt.

Our subordinated debt securities will be issued under the subordinated debt indenture, as described below, and will be subordinate in right of payment to all of our “senior debt,” as defined in the subordinated debt indenture. The prospectus supplement for any series of subordinated debt securities or the information incorporated in this prospectus by reference will indicate the approximate amount of senior debt outstanding as of the end of our most recent fiscal quarter. Neither indenture limits our ability to incur additional senior debt, unless otherwise described in the prospectus supplement relating to any series of debt securities.

When we refer to “senior debt securities” in this prospectus, we mean the senior debt securities of Orion Marine Group, Inc., unless the context requires otherwise. When we refer to “subordinated debt securities” in this prospectus, we mean the subordinated debt securities of Orion Marine Group, Inc., unless the context requires otherwise. When we refer to “debt securities” in this prospectus, we mean both the senior debt securities and the subordinated debt securities, unless the context requires otherwise.

The Senior Debt Indenture and the Subordinated Debt Indenture

Our senior debt securities and the subordinated debt securities are each governed by a document called an indenture — the senior debt indenture, in the case of the senior debt securities, and the subordinated debt indenture, in the case of the subordinated debt securities. Each indenture is a contract between us and a trustee to be named therein. These indentures governing our debt securities are substantially identical, except for the provisions relating to subordination, which are included only in the subordinated debt indenture.

The trustee under each indenture has two main roles:

See “— Concerning the Trustee” below for more information about the trustee.

When we refer to the indenture or the trustee with respect to any of our debt securities, we mean the indenture under which those debt securities are issued and the trustee under that indenture.

TABLE OF CONTENTS

We May Issue Many Series of Debt Securities

We may issue as many distinct series of debt securities under a debt indenture as we wish. This section of the prospectus summarizes terms of the securities that apply generally to all series. The provisions of each indenture allow us not only to issue debt securities with terms different from those of debt securities previously issued under that indenture, but also to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that series. We will describe most of the financial and other specific terms of a series including any additional terms of any guarantee, if applicable, whether it be a series of the senior debt securities or subordinated debt securities, in the prospectus supplement accompanying this prospectus. Those terms may vary from the terms described here.

As you read this section of the prospectus, please remember that the specific terms of your debt security will be described in the accompanying prospectus supplement and, if applicable, that description may modify or replace the general terms described in this section. If there are any differences between your prospectus supplement and this prospectus, your prospectus supplement will control. Thus, the statements we make in this section may not apply to your debt security.

When we refer to a series of debt securities, we mean a series issued under the applicable indenture. When we refer to your prospectus supplement, we mean the prospectus supplement describing the specific terms of the debt security you purchase. The terms used in your prospectus supplement have the meanings described in this prospectus, unless otherwise specified.

Amounts That We May Issue

Neither indenture limits the aggregate amount of debt securities that we may issue or the number of series or the aggregate amount of any particular series. In addition, the indentures and the debt securities do not limit our ability to incur other indebtedness or to issue other securities, unless otherwise described in the prospectus supplement relating to any series of debt securities. Also, we are not subject to financial or similar restrictions by the terms of the debt securities, unless otherwise described in the prospectus supplement relating to any series of debt securities.

Principal Amount, Stated Maturity and Maturity

The principal amount of a debt security means the principal amount payable at its stated maturity, unless that amount is not determinable, in which case the principal amount of a debt security is its face amount. Any debt securities owned by us or any of our affiliates are not deemed to be outstanding for certain determinations under the indenture.

The term “stated maturity” with respect to any debt security means the day on which the principal amount of the debt security is scheduled to become due. The principal may become due sooner, by reason of redemption or acceleration after a default or otherwise in accordance with the terms of the debt security. The day on which the principal actually becomes due, whether at the stated maturity or earlier, is called the “maturity” of the principal.

We also use the terms “stated maturity” and “maturity” to refer to the days when other payments become due. For example, we refer to a regular interest payment date when an installment of interest is scheduled to become due as the “stated maturity” of that installment.

When we refer to the “stated maturity” or the “maturity” of a debt security without specifying a particular payment, we mean the stated maturity or maturity, as the case may be, of the principal.

This Section Is Only a Summary

The indentures and their associated documents, including your debt security, contain the full legal text of the matters described in this section and your prospectus supplement. We have filed forms of the indentures with the SEC as exhibits to our registration statement of which this prospectus forms a part. See “Where You Can Find More Information” above for information on how to obtain copies of them.

TABLE OF CONTENTS

This section and your prospectus supplement summarize all the material terms of the indentures and your debt security. They do not, however, describe every aspect of the indentures and your debt security. For example, in this section and your prospectus supplement, we use terms that have been given special meaning in the indentures, but we describe the meaning for only the more important of those terms.

Governing Law

The indentures, the debt securities and any guarantees of those debt securities will be governed by New York law.

Currency of Debt Securities

Amounts that become due and payable on a debt security in cash will be payable in a currency, currencies or currency units specified in the accompanying prospectus supplement. We refer to this currency, currencies or currency units as a “specified currency.” The specified currency for a debt security will be U.S. dollars, unless your prospectus supplement states otherwise. Some debt securities may have different specified currencies for principal and interest. You will have to pay for your debt securities by delivering the requisite amount of the specified currency for the principal to us or the underwriters, agents or dealers that we name in your prospectus supplement, unless other arrangements have been made between you and us or you and that firm. We will make payments on a debt security in the specified currency, except as described below in “— Payment Mechanics for Debt Securities.”

Form of Debt Securities

We will issue each debt security in global — i.e., book-entry — form only, unless we specify otherwise in the applicable prospectus supplement. Debt securities in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the debt securities represented by that global security. Those who own beneficial interests in a global debt security will do so through participants in the depositary’s securities clearance system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. We describe book-entry securities below under “Legal Ownership and Book-Entry Issuance.”

In addition, we will issue each debt security in fully registered form, without coupons.

Types of Debt Securities

We may issue any of the following types of senior debt securities or subordinated debt securities:

Fixed Rate Debt Securities

A debt security of this type will bear interest at a fixed rate described in your prospectus supplement. This type includes zero coupon debt securities, which bear no interest and are instead issued at a price usually significantly lower than the principal amount. See “— Original Issue Discount Debt Securities” below for more information about zero coupon and other original issue discount debt securities.

Each fixed rate debt security, except any zero coupon debt security, will bear interest from its original issue date or from the most recent date to which interest on the debt security has been paid or made available for payment. Interest will accrue on the principal of a fixed rate debt security at the fixed yearly rate stated in the applicable prospectus supplement, until the principal is paid or made available for payment or the debt security is exchanged. Each payment of interest due on an interest payment date or the date of maturity will include interest accrued from and including the last date to which interest has been paid, or made available for payment, or from the issue date if none has been paid or made available for payment, to but excluding the interest payment date or the date of maturity. We will compute interest on fixed rate debt securities on the basis of a 360-day year of twelve 30-day months. We will pay interest on each interest payment date and at maturity as described below under “— Payment Mechanics for Debt Securities.”

Floating Rate Debt Securities

A debt security of this type will bear interest at rates that are determined by reference to an interest rate formula. In some cases, the rates may also be adjusted by adding or subtracting a spread or multiplying by a spread multiplier and may be subject to a minimum rate or a maximum rate. If a debt security is a floating rate debt security, the formula and any adjustments that apply to the interest rate will be specified in the applicable prospectus supplement.

TABLE OF CONTENTS

Each floating rate debt security will bear interest from its original issue date or from the most recent date to which interest on the debt security has been paid or made available for payment. Interest will accrue on the principal of a floating rate debt security at the yearly rate determined according to the interest rate formula stated in the applicable prospectus supplement, until the principal is paid or made available for payment or the security is exchanged. We will pay interest on each interest payment date and at maturity as described below under “— Payment Mechanics for Debt Securities.”

Calculation of Interest.  Calculations relating to floating rate debt securities will be made by the calculation agent, an institution that we appoint as our agent for this purpose. The prospectus supplement for a particular floating rate debt security will name the institution that we have appointed to act as the calculation agent for that debt security as of its original issue date. We may appoint a different institution to serve as calculation agent from time to time after the original issue date of the debt security without your consent and without notifying you of the change.

For each floating rate debt security, the calculation agent will determine, on the corresponding interest calculation or determination date, as described in the applicable prospectus supplement, the interest rate that takes effect on each interest reset date. In addition, the calculation agent will calculate the amount of interest that has accrued during each interest period — i.e., the period from and including the original issue date, or the last date to which interest has been paid or made available for payment, to but excluding the payment date. For each interest period, the calculation agent will calculate the amount of accrued interest by multiplying the face or other specified amount of the floating rate debt security by an accrued interest factor for the interest period. This factor will equal the sum of the interest factors calculated for each day during the interest period. The interest factor for each day will be expressed as a decimal and will be calculated by dividing the interest rate, also expressed as a decimal, applicable to that day by 360 or by the actual number of days in the year, as specified in the applicable prospectus supplement.

Upon the request of the holder of any floating rate debt security, the calculation agent will provide for that debt security the interest rate then in effect — and, if determined, the interest rate that will become effective on the next interest reset date. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any interest period, will be final and binding in the absence of manifest error.

All percentages resulting from any calculation relating to a debt security will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. All amounts used in or resulting from any calculation relating to a floating rate debt security will be rounded upward or downward, as appropriate, to the nearest cent, in the case of U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.

In determining the base rate that applies to a floating rate debt security during a particular interest period, the calculation agent may obtain rate quotes from various banks or dealers active in the relevant market, as described in the applicable prospectus supplement. Those reference banks and dealers may include the calculation agent itself and its affiliates, as well as any underwriter, dealer or agent participating in the distribution of the relevant floating rate debt securities and its affiliates.

Indexed Debt Securities

A debt security of this type provides that the principal amount payable at its maturity, and the amount of interest payable on an interest payment date, will be determined by reference to:

TABLE OF CONTENTS

If you are a holder of an indexed debt security, you may receive an amount at maturity that is greater than or less than the face amount of your debt security depending upon the value of the applicable index at maturity. The value of the applicable index will fluctuate over time.

If you purchase an indexed debt security, your prospectus supplement will include information about the relevant index and about how amounts that are to become payable will be determined by reference to the price or value of that index. The prospectus supplement will also identify the calculation agent that will calculate the amounts payable with respect to the indexed debt security. The calculation agent may exercise significant discretion in determining such amounts.

Original Issue Discount Debt Securities

A fixed rate debt security, a floating rate debt security or an indexed debt security may be an original issue discount debt security. A debt security of this type is issued at a price lower than its principal amount and provides that, upon redemption or acceleration of its maturity, an amount less than its principal amount will be payable. An original issue discount debt security may be a zero coupon debt security. A debt security issued at a discount to its principal may, for U.S. federal income tax purposes, be considered an original issue discount debt security, regardless of the amount payable upon redemption or acceleration of maturity. The U.S. federal income tax consequences of owning an original issue discount debt security may be described in the applicable prospectus supplement.

Information in the Prospectus Supplement

A prospectus supplement will describe the specific terms of a particular series of debt securities, which will include some or all of the following:

TABLE OF CONTENTS

Redemption and Repayment

Unless otherwise indicated in the applicable prospectus supplement, a debt security will not be entitled to the benefit of any sinking fund — that is, we will not deposit money on a regular basis into any separate custodial account to repay the debt securities. In addition, we will not be entitled to redeem a debt security before its stated maturity unless the prospectus supplement specifies a redemption commencement date. You will not be entitled to require us to buy a debt security from you before its stated maturity unless your prospectus supplement specifies one or more repayment dates.

If your applicable prospectus supplement specifies a redemption commencement date or a repayment date, it will also specify one or more redemption prices or repayment prices, which may be expressed as a percentage of the principal amount of the debt security. It may also specify one or more redemption periods during which the redemption prices relating to a redemption of debt securities during those periods will apply.

TABLE OF CONTENTS

If we redeem less than all the debt securities of any series, we will, at least 60 days before the redemption date set by us or any shorter period that is satisfactory to the trustee, notify the trustee of the redemption date, of the principal amount of debt securities to be redeemed and if applicable, of the tenor of the debt securities to be redeemed. The trustee will select from the outstanding securities of the series the particular debt securities to be redeemed not more than 60 days before the redemption date. This procedure will not apply to any redemption of a single debt security.

If your prospectus supplement specifies a redemption commencement date, the debt security will be redeemable at our option at any time on or after that date or at a specified time or times. If we redeem the debt security, we will do so at the specified redemption price, together with interest accrued to the redemption date. If different prices are specified for different redemption periods, the price we pay will be the price that applies to the redemption period during which the debt security is redeemed.

If your prospectus supplement specifies a repayment date, the debt security will be repayable at the holder’s option on the specified repayment date at the specified repayment price, together with interest accrued to the repayment date.

If we exercise an option to redeem any debt security, we will give to the holder written notice of the principal amount of the debt security to be redeemed, not less than 30 days nor more than 60 days before the applicable redemption date. We will give the notice in the manner described below in “— Notices.”

If a debt security represented by a global debt security is subject to repayment at the holder’s option, the depositary or its nominee, as the holder, will be the only person that can exercise the right to repayment. Any indirect owners who own beneficial interests in the global debt security and wish to exercise a repayment right must give proper and timely instructions to their banks or brokers through which they hold their interests, requesting that they notify the depositary to exercise the repayment right on their behalf. Different firms have different deadlines for accepting instructions from their customers, and you should take care to act promptly enough to ensure that your request is given effect by the depositary before the applicable deadline for exercise.

Street name and other indirect owners should contact their banks or brokers for information about how to exercise a repayment right in a timely manner.

We or our affiliates may purchase debt securities from investors who are willing to sell from time to time, either in the open market at prevailing prices or in private transactions at negotiated prices. Debt securities that we or they purchase may, at our discretion, be held, resold or canceled.

Mergers and Similar Transactions

We are generally permitted to merge or consolidate with another entity. We are also permitted to sell our assets substantially as an entirety to another entity. With regard to any series of debt securities, however, unless otherwise indicated in the applicable prospectus supplement, we may not take any of these actions unless all the following conditions are met:

TABLE OF CONTENTS

If the conditions described above are satisfied with respect to the debt securities of any series, we will not need to obtain the approval of the holders of those debt securities in order to merge or consolidate or to sell our assets. Also, these conditions will apply only if we wish to merge or consolidate with another entity or sell our assets substantially as an entirety to another entity. We will not need to satisfy these conditions if we enter into other types of transactions, including any transaction in which we acquire the stock or assets of another entity, any transaction that involves a change of control of our company but in which we do not merge or consolidate and any transaction in which we sell less than substantially all of our assets.

Any limitation applicable to the ability of the subsidiary guarantors to participate in any of the actions described above will be set forth in the prospectus supplement for such series of debt securities.

Subordination Provisions

Holders of subordinated debt securities should recognize that contractual provisions in the subordinated debt indenture may prohibit us from making payments on those securities. Subordinated debt securities are subordinate and junior in right of payment, to the extent and in the manner stated in the subordinated debt indenture or in the provisions of the applicable debt securities, to all of our senior debt, as defined in the subordinated debt indenture, including all debt securities we have issued and will issue under the senior debt indenture.

The subordinated debt indenture defines “senior debt” as the principal of and premium, if any, and interest on all of our indebtedness, other than the subordinated debt securities, whether outstanding on the date of the indenture or thereafter created, incurred or assumed, which is (a) for money borrowed, (b) evidenced by a note or similar instrument given in connection with the acquisition of any businesses, properties or assets of any kind or (c) obligations of Orion Marine Group, Inc. as lessee under leases required to be capitalized on the balance sheet of the lessee under generally accepted accounting principles or leases of property or assets made as part of any sale and lease-back transaction to which we are a party. For the purpose of this definition, “interest” includes interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to us, to the extent that the claim for post-petition interest is allowed in the proceeding. Also for the purpose of this definition, “indebtedness” includes indebtedness of others guaranteed by us and amendments, renewals, extensions, modifications and refundings of any indebtedness or obligation of the kinds described in the first sentence of this paragraph. However, “indebtedness” for the purpose of this definition does not include any indebtedness or obligation if the instrument creating or evidencing the indebtedness or obligation, or under which the indebtedness or obligation is outstanding, provides that the indebtedness or obligation is not superior in right of payment to the subordinated debt securities.

The subordinated debt indenture provides that, unless all principal of and any premium or interest on the senior debt has been paid in full, no payment or other distribution may be made in respect of any subordinated debt securities in the following circumstances:

TABLE OF CONTENTS

If the trustee under the subordinated debt indenture or any holders of the subordinated debt securities receive any payment or distribution that they know is prohibited under the subordination provisions, then the trustee or the holders will have to repay that money to the holders of the senior debt.

Even if the subordination provisions prevent us from making any payment when due on the subordinated debt securities of any series, we will be in default on our obligations under that series if we do not make the payment when due. This means that the trustee under the subordinated debt indenture and the holders of that series can take action against us, but they will not receive any money until the claims of the holders of senior debt have been fully satisfied.

Covenants

The following covenants apply to us with respect to the debt securities of each series we issue unless otherwise specified in the applicable prospectus supplement.

Maintenance of Properties.  We must maintain all properties used in our business in good condition. However, we may discontinue the maintenance or operation of any of our properties if in our judgment, discontinuance is desirable in the conduct of our business and is not disadvantageous in any material respect to the holders of debt securities.

Insurance.  We must keep all of our insurable properties insured against loss or damage with insurers of recognized responsibility. The insurance must be in commercially reasonable amounts and types.

Existence.  Except as described under “— Mergers and Similar Transactions,” we must do or cause to be done all things necessary to preserve and keep in full force and effect our existence, rights and franchises. However, we are not required to preserve any right or franchise if we determine that the preservation of the right or franchise is no longer desirable in the conduct of our business and that the loss of the right or franchise is not disadvantageous in any material respect to the holders of the debt securities.

Payment of Taxes and Other Claims.  We are required to pay or discharge or cause to be paid or discharged:

We must pay these taxes and other claims before they become delinquent. However, we are not required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

Provision of Financial Information.  We will file with the trustee, within 15 days after we file the same with the SEC, copies of the annual reports and of the information, documents and other reports that we may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. If we are not required to file with the SEC information, documents or reports pursuant to either of those sections, then we will file with the trustee and the SEC such reports, if any, as may be prescribed by the SEC at such time.

Additional covenants described in the applicable prospectus supplement may apply to us and, if applicable, the subsidiary guarantors, with respect to a particular series of debt securities.

TABLE OF CONTENTS

Defeasance and Covenant Defeasance

The provisions for full defeasance and covenant defeasance described below apply to each senior and subordinated debt security, and any applicable guarantee, if so indicated in the applicable prospectus supplement. In general, we expect these provisions to apply to each debt security that has a specified currency of U.S. dollars and is not a floating rate or indexed debt security.

Full Defeasance.  If there is a change in U.S. federal tax law, as described below, we can legally release ourselves and any subsidiary guarantors from all payment and other obligations on any debt securities. This is called full defeasance. For us to do so, each of the following must occur:

If we ever fully defeased your debt security, you would have to rely solely on the trust deposit for payments on your debt security. You would not be able to look to us for payment if there was any shortfall.

Covenant Defeasance.  Under current U.S. federal tax law, we can make the same type of deposit described above and we and any subsidiary guarantors will be released from the restrictive covenants relating to your debt security listed in the bullets below and any additional restrictive covenants that may be described in your prospectus supplement. This is called covenant defeasance. In that event, you would lose the protection of those restrictive covenants. In order to achieve covenant defeasance for any debt securities, we must take the same steps as are required for full defeasance.

If we accomplish covenant defeasance with regard to your debt security, the following provisions of the applicable indenture and your debt security would no longer apply:

TABLE OF CONTENTS

If we accomplish covenant defeasance on your debt security, we must still repay your debt security if there is any shortfall in the trust deposit. You should note, however, that if one of the remaining events of default were to occur, such as our bankruptcy, and your debt security became immediately due and payable, there may be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Default, Remedies and Waiver of Default

You will have special rights if an event of default with respect to your series of debt securities occurs and is continuing, as described in this subsection.

Events of Default.  Unless your prospectus supplement says otherwise, when we refer to an event of default with respect to any series of debt securities, we mean any of the following:

Remedies If an Event of Default Occurs

If you are the holder of a subordinated debt security, all the remedies available upon the occurrence of an event of default under the subordinated debt indenture will be subject to the restrictions on the subordinated debt securities described above under “— Subordination Provisions.”

If an event of default has occurred with respect to any series of debt securities and has not been cured or waived, the trustee or the holders of not less than 25% in principal amount of outstanding debt securities of that series may declare the entire principal amount of the debt securities of that series to be due immediately. If the event of default occurs because of events in bankruptcy, insolvency or reorganization relating to us the entire principal amount of the debt securities of that series will be automatically accelerated, without any action by the trustee or any holder.

Each of the situations described above is called an acceleration of the maturity of the affected series of debt securities. If the maturity of any series is accelerated, a judgment for payment has not yet been obtained, we pay or deposit with the trustee an amount sufficient to pay all amounts due on the securities of the series, and all events of default with respect to the series, other than the nonpayment of the accelerated principal, have been cured or waived, then the holders of a majority in principal amount of the outstanding debt securities of that series may cancel the acceleration for the entire series.

TABLE OF CONTENTS

If an event of default occurs, the trustee will have special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the relevant indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

Except as described in the prior paragraph, the trustee is not required to take any action under the relevant indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an indemnity. If the trustee is provided with an indemnity reasonably satisfactory to it, the holders of a majority in principal amount of all debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee with respect to that series. These majority holders may also direct the trustee in performing any other action under the applicable indenture with respect to the debt securities of that series.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to any debt security or any guarantee, all of the following must occur:

You are entitled at any time, however, to bring a lawsuit for the payment of money due on your debt security on or after its due date.

Waiver of Default.  The holders of not less than a majority in principal amount of the outstanding debt securities of a series may waive a default for all debt securities of that series. If this happens, the default will be treated as if it has not occurred. No one can waive a payment default on your debt security or a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security of the series, however, without the approval of the particular holder of that debt security.

Annual Provision of Information to the Trustee About Defaults.  We, and if the due and punctual payment of principal of, and interest on one or more series of debt securities is guaranteed, the subsidiary guarantors, will furnish to each trustee every year a written statement of two of our officers certifying that, to their knowledge, we and the subsidiary guarantors, if applicable, are in compliance with the applicable indenture and the debt securities issued under it, or else specifying any default under the indenture.

Book-entry and other indirect owners should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of the maturity. Book-entry and other indirect owners are described below under “Legal Ownership and Book-Entry Issuance.”

Changes of the Indentures Requiring Each Holder’s Approval

There are certain changes that cannot be made without the approval of each holder of a debt security affected by the change under a particular indenture. Here is a list of those types of changes:

TABLE OF CONTENTS

Modification of Subordination Provisions

We may not amend the subordinated debt indenture governing the subordinated debt securities we have issued to alter the subordination of any outstanding subordinated debt securities we have issued without the written consent of each holder of senior debt then outstanding who would be adversely affected. In addition, we may not modify the subordination provisions of the subordinated debt indenture governing the subordinated debt securities we have issued in a manner that would adversely affect the outstanding subordinated debt securities we have issued of any one or more series in any material respect, without the consent of the holders of a majority in aggregate principal amount of all affected series, voting together as one class.

Changes of the Indentures Not Requiring Approval

Another type of change does not require any approval by holders of the debt securities of an affected series. These changes are limited to clarifications and changes that would not adversely affect the debt securities of that series in any material respect. Nor do we need any approval to make changes that affect only debt securities or any guarantees of that series to be issued under the applicable indenture after the changes take effect or to add a guarantee to any outstanding debt securities not guaranteed or to comply with the rules or regulations of any securities exchange or automated quotation system on which any of the debt securities may be listed or traded.

We may also make changes or obtain waivers that do not adversely affect a particular debt security or the guarantee of that debt security, even if they affect other debt securities and guarantees. In those cases, we do not need to obtain the approval of the holder of the unaffected debt security; we need only obtain any required approvals from the holders of the affected debt securities.

Changes of the Indentures Requiring Majority Approval

Any other change to a particular indenture and the debt securities issued under that indenture would require the following approval:

In each case, the required approval must be given by written consent.

TABLE OF CONTENTS

The same majority approval would be required for us or the subsidiary guarantors, if applicable, to obtain a waiver of any of the applicable covenants in the indenture. The covenants include the promises we or the subsidiary guarantors, if applicable, make about merging and similar transactions, which are described above under “— Mergers and Similar Transactions.” If the requisite holders approve a waiver of a covenant, neither we nor the subsidiary guarantors, as the case may be, will have to comply with it. The holders, however, cannot approve a waiver of any provision in a particular debt security, or in the applicable indenture as it affects that debt security, that cannot be changed without the approval of the holder of that debt security as described above in “— Changes of the Indentures Requiring Each Holder’s Approval,” unless that holder approves the waiver.

Book-entry and other indirect owners should consult their banks or brokers for information on how approval may be granted or denied if we seek to change an indenture or any debt securities or request a waiver.

Special Rules for Action by Holders

When holders take any action under a debt indenture, such as giving a notice of default, declaring an acceleration, approving any change or waiver or giving the trustee an instruction, we will apply the following rules.

Only Outstanding Debt Securities Are Eligible

Only holders of outstanding debt securities of the applicable series will be eligible to participate in any action by holders of debt securities of that series. Also, we will count only outstanding debt securities in determining whether the various percentage requirements for taking action have been met. For these purposes, a debt security will not be “outstanding”:

Eligible Principal Amount of Some Debt Securities

In some situations, we may follow special rules in calculating the principal amount of a debt security that is to be treated as outstanding for the purposes described above. This may happen, for example, if the principal amount is payable in a non-U.S. dollar currency, increases over time or is not to be fixed until maturity.

For any debt security of the kind described below, we will decide how much principal amount to attribute to the debt security as follows:

TABLE OF CONTENTS

Determining Record Dates for Action by Holders

We generally will be entitled to set any day as a record date for the purpose of determining the holders that are entitled to take action under either indenture. In certain limited circumstances, only the trustee will be entitled to set a record date for action by holders. If we or the trustee set a record date for an approval or other action to be taken by holders, that vote or action may be taken only by persons or entities who are holders on the record date and must be taken during the period that we specify for this purpose, or that the trustee specifies if it sets the record date. We or the trustee, as applicable, may shorten or lengthen this period from time to time. This period, however, may not extend beyond the 180th day after the record date for the action. In addition, record dates for any global debt security may be set in accordance with procedures established by the depositary from time to time. Accordingly, record dates for global debt securities may differ from those for other debt securities.

Form, Exchange and Transfer of Debt Securities

Unless we indicate otherwise in your prospectus supplement, the debt securities will be issued:

Holders may exchange their debt securities for debt securities of the same series in any authorized denominations, as long as the total principal amount is not changed.

Holders may exchange or transfer their debt securities at the office of the trustee. They may also replace lost, stolen, destroyed or mutilated debt securities at that office. We have appointed the trustee to act as our agent for registering debt securities in the names of holders and transferring and replacing debt securities.

Holders will not be required to pay a service charge to transfer or exchange their debt securities, but they may be required to pay for any tax or other governmental charge associated with the registration, exchange or transfer. The transfer or exchange, and any replacement, will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership. The transfer agent may require an indemnity before replacing any debt securities.

If a debt security is issued as a global debt security, only the depositary — e.g., DTC, Euroclear and Clearstream — will be entitled to transfer and exchange the debt security as described in this subsection, since the depositary will be the sole holder of the debt security.

The rules for exchange described above apply to exchange of debt securities for other debt securities of the same series and kind. If a debt security is convertible into or exchangeable for our common or preferred stock, the rules governing that type of conversion or exchange will be described in the applicable prospectus supplement.

Payment Mechanics for Debt Securities

Who Receives Payment?

If interest is due on a debt security on an interest payment date, we will pay the interest to the person in whose name the debt security is registered at the close of business on the regular record date relating to the interest payment date as described below under “— Payment and Record Dates for Interest.” If interest is due at maturity but on a day that is not an interest payment date, we will pay the interest to the person entitled to receive the principal of the debt security. If principal or another amount besides interest is due on a debt security at maturity, we will pay the amount to the holder of the debt security against surrender of the debt security at a proper place of payment or, in the case of a global debt security, in accordance with the applicable policies of the depositary, DTC, Euroclear and Clearstream, as applicable.

TABLE OF CONTENTS

Payment and Record Dates for Interest

Unless we specify otherwise in the applicable prospectus supplement, interest on any fixed rate debt security will be payable semiannually each May 15 and November 15 and at maturity, and the regular record date relating to an interest payment date for any fixed rate debt security will be the May 1 or November 1 next preceding that interest payment date. The regular record date relating to an interest payment date for any floating rate debt security will be the 15th calendar day before that interest payment date. These record dates will apply regardless of whether a particular record date is a “business day,” as defined below. For the purpose of determining the holder at the close of business on a regular record date when business is not being conducted, the close of business will mean 5:00 p.m., New York City time, on that day.

Business Day.  The term “business day” means, with respect to the debt securities of a series, a Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in the place of payment for the debt securities of that series are authorized or obligated by law or executive order to close and that satisfies any other criteria specified in the applicable prospectus supplement.

How We Will Make Payments Due in U.S. Dollars

We will follow the practice described in this subsection when paying amounts due in U.S. dollars. Payments of amounts due in other currencies will be made as described in the next subsection.

Payments on Global Debt Securities.  We will make payments on a global debt security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect owners who own beneficial interests in the global debt security. An indirect owner’s right to receive those payments will be governed by the rules and practices of the depositary and its participants, as described below in the section entitled “Legal Ownership and Book-Entry Issuance — What Is a Global Security?”

Payments on Non-Global Debt Securities.  We will make payments on a debt security in non-global, registered form as follows. We will pay interest that is due on an interest payment date by check mailed on the interest payment date to the holder at his or her address shown on the trustee’s records as of the close of business on the regular record date. We will make all other payments by check to the paying agent described below, against surrender of the debt security. All payments by check will be made in next-day funds — i.e., funds that become available on the day after the check is cashed.

Alternatively, if a non-global debt security has a face amount of at least $1,000,000 and the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City, on the due date. To request a wire payment, the holder must give the paying agent appropriate wire transfer instructions at least five business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person or entity who is the holder on the relevant regular record date. In the case of any other payment, payment will be made only after the debt security is surrendered to the paying agent. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

Book-entry and other indirect owners should consult their banks or brokers for information on how they will receive payments on their debt securities.

How We Will Make Payments Due in Other Currencies

We will follow the practice described in this subsection when paying amounts that are due in a specified currency other than U.S. dollars.

Payments on Global Debt Securities.  We will make payments on a global debt security in accordance with the applicable policies as in effect from time to time of the depositary, which will be DTC, Euroclear or Clearstream. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all debt securities in global form. We understand that DTC’s policies, as currently in effect, are as follows.

TABLE OF CONTENTS

Unless otherwise indicated in your prospectus supplement, if you are an indirect owner of global debt securities denominated in a specified currency other than U.S. dollars and if you have the right to elect to receive payments in that other currency and do so elect, you must notify the participant through which your interest in the global debt security is held of your election:

Your participant must, in turn, notify DTC of your election on or before the third DTC business day after that regular record date, in the case of a payment of interest, and on or before the 12th DTC business day prior to the stated maturity, or on the redemption or repayment date if your debt security is redeemed or repaid earlier, in the case of a payment of principal or any premium.

DTC, in turn, will notify the paying agent of your election in accordance with DTC’s procedures.

If complete instructions are received by the participant and forwarded by the participant to DTC, and by DTC to the paying agent, on or before the dates noted above, the paying agent, in accordance with DTC’s instructions, will make the payments to you or your participant by wire transfer of immediately available funds to an account maintained by the payee with a bank located in the country issuing the specified currency or in another jurisdiction acceptable to us and the paying agent.

If the foregoing steps are not properly completed, we expect DTC to inform the paying agent that payment is to be made in U.S. dollars. In that case, we or our agent will convert the payment to U.S. dollars in the manner described below under “— Conversion to U.S. Dollars.” We expect that we or our agent will then make the payment in U.S. dollars to DTC, and that DTC in turn will pass it along to its participants.

Indirect owners of a global debt security denominated in a currency other than U.S. dollars should consult their banks or brokers for information on how to request payment in the specified currency.

Payments on Non-Global Debt Securities.  Except as described in the last paragraph under this heading, we will make payments on debt securities in non-global form in the applicable specified currency. We will make these payments by wire transfer of immediately available funds to any account that is maintained in the applicable specified currency at a bank designated by the holder and which is acceptable to us and the trustee. To designate an account for wire payment, the holder must give the paying agent appropriate wire instructions at least five business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person or entity who is the holder on the regular record date. In the case of any other payment, the payment will be made only after the debt security is surrendered to the paying agent. Any instructions, once properly given, will remain in effect unless and until new instructions are properly given in the manner described above.

If a holder fails to give instructions as described above, we will notify the holder at the address in the trustee’s records and will make the payment within five business days after the holder provides appropriate instructions. Any late payment made in these circumstances will be treated under the applicable indenture as if made on the due date, and no interest will accrue on the late payment from the due date to the date paid.

Although a payment on a debt security in non-global form may be due in a specified currency other than U.S. dollars, we will make the payment in U.S. dollars if the holder asks us to do so. To request U.S. dollar payment, the holder must provide appropriate written notice to the trustee at least five business days before the next due date for which payment in U.S. dollars is requested. In the case of any interest payment due on an interest payment date, the request must be made by the person or entity who is the holder on the regular record date. Any request, once properly made, will remain in effect unless and until revoked by notice properly given in the manner described above.

Book-entry and other indirect owners of a debt security with a specified currency other than U.S. dollars should contact their banks or brokers for information about how to receive payments in the specified currency or in U.S. dollars.

TABLE OF CONTENTS

Conversion to U.S. Dollars.  When we are asked by a holder to make payments in U.S. dollars of an amount due in another currency, either on a global debt security or a non-global debt security as described above, the exchange rate agent described below will calculate the U.S. dollar amount the holder receives in the exchange rate agent’s discretion.

A holder that requests payment in U.S. dollars will bear all associated currency exchange costs, which will be deducted from the payment.

When the Specified Currency Is Not Available.  If we are obligated to make any payment in a specified currency other than U.S. dollars, and the specified currency or any successor currency is not available to us due to circumstances beyond our control — such as the imposition of exchange controls or a disruption in the currency markets — we will be entitled to satisfy our obligation to make the payment in that specified currency by making the payment in U.S. dollars, on the basis of the exchange rate determined by the exchange rate agent described below, in its discretion.

The foregoing will apply to any debt security, whether in global or non-global form, and to any payment, including a payment at maturity. Any payment made under the circumstances and in a manner described above will not result in a default under any debt security or the applicable indenture.

Exchange Rate Agent.  If we issue a debt security in a specified currency other than U.S. dollars, we will appoint a financial institution to act as the exchange rate agent and will name the institution initially appointed when the debt security is originally issued in the applicable prospectus supplement. We may change the exchange rate agent from time to time after the original issue date of the debt security without your consent and without notifying you of the change.

All determinations made by the exchange rate agent will be in its sole discretion unless we state in the applicable prospectus supplement that any determination requires our approval. In the absence of manifest error, those determinations will be conclusive for all purposes and binding on you and us, without any liability on the part of the exchange rate agent.

Payment When Offices Are Closed

If any payment is due on a debt security on a day that is not a business day, we will make the payment on the next day that is a business day. Payments postponed to the next business day in this situation will be treated under the applicable indenture as if they were made on the original due date. Postponement of this kind will not result in a default under any debt security or the applicable indenture, and no interest will accrue on the postponed amount from the original due date to the next day that is a business day. The term “business day” has a special meaning, which we describe above under “— Payment and Record Dates for Interest.”

Paying Agent

We may appoint one or more financial institutions to act as our paying agents, at whose designated offices debt securities in non-global entry form may be surrendered for payment at their maturity. We call each of those offices a paying agent. We may add, replace or terminate paying agents from time to time. We may also choose to act as our own paying agent. Initially, we will appoint the trustee as the paying agent. We must notify the trustee of changes in the paying agents.

Unclaimed Payments

Regardless of who acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount is due to a holder will be repaid to us. After that two-year period, the holder may look only to us for payment and not to the trustee, any other paying agent or anyone else.

Notices

Notices to be given to holders of a global debt security will be given only to the depositary, in accordance with its applicable policies as in effect from time to time. Notices to be given to holders of debt securities not in global form will be sent by mail to the respective addresses of the holders as they appear in the trustee’s records. Neither the failure to give any notice to a particular holder, nor any defect in a notice given to a particular holder, will affect the sufficiency of any notice given to another holder.

TABLE OF CONTENTS

Book-entry and other indirect owners should consult their banks or brokers for information on how they will receive notices.

Concerning the Trustee

We will appoint a trustee for the senior debt securities and the subordinated debt securities in the respective indentures. We may appoint other parties to serve as trustee or co-trustee as may be indicated in the applicable prospectus supplement. If an actual or potential event of default occurs with respect to any of these securities, the trustee may be considered to have a conflicting interest for purposes of the Trust Indenture Act of 1939. In that case, the trustee may be required to resign under one or more of the indentures, and we would be required to appoint a successor trustee. For this purpose, a “potential” event of default means an event that would be an event of default if the requirements for giving us default notice or for the default having to exist for a specific period of time were disregarded.

DESCRIPTION OF THE GUARANTEES

Certain of our subsidiaries, whom we refer to as the “subsidiary guarantors,” may guarantee (either fully or unconditionally or in a limited manner) the due and punctual payment of the principal of, and any premium or interest on, one or more series of debt securities that we may issue, whether at maturity, by acceleration, redemption, repayment or otherwise, in accordance with the terms of such guarantee and the indenture. In case of the failure of Orion Marine Group, Inc. punctually to pay any principal, premium or interest on any guaranteed debt security, the subsidiary guarantors will cause any such payment to be made as it becomes due and payable, whether at maturity, by acceleration, redemption, repayment or otherwise, and as if such payment were made by Orion Marine Group, Inc. The particular terms of the guarantee, if any, will be set forth in a prospectus supplement relating to the guaranteed debt securities. Any guarantee by the subsidiary guarantors will be of payment only and not of collection.

TABLE OF CONTENTS

LEGAL OWNERSHIP AND BOOK-ENTRY ISSUANCE

In this section, we describe special considerations that will apply to registered securities issued in global — i.e., book-entry — form. First we describe the difference between legal ownership and indirect ownership of registered securities. Then we describe special provisions that apply to global securities.

Who Is the Legal Owner of a Registered Security?

Each debt security or share of common or preferred stock in registered form will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. We refer to those who have securities registered in their own names, on the books that we or the trustee or other agent maintain for this purpose, as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those who, indirectly through others, own beneficial interests in securities that are not registered in their own names as indirect owners of those securities. As we discuss below, indirect owners are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect owners.

Book-Entry Owners

We expect to issue debt securities and preferred stock in book-entry form only. However, we may issue common stock in book-entry form. This means those securities will be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Under each indenture or other applicable agreement, only the person in whose name a security is registered is recognized as the holder of that security. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities and we will make all payments on the securities, including deliveries of common or preferred stock in exchange for exchangeable debt securities, to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect owners, and not holders, of the securities.

Street Name Owners

In the future we may terminate a global security or issue securities initially in non-global form. In these cases, investors may choose to hold their securities in their own names or in street name. Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities and we will make all payments on those securities, including deliveries of common or preferred shares in exchange for exchangeable debt securities, to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect owners, not holders, of those securities.

TABLE OF CONTENTS

Legal Holders

Our obligations, as well as the obligations of the trustee under either indenture and the obligations, if any, of any other third parties employed by us, the trustee or any agents, run only to the holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect owner of a security or has no choice because we are issuing the securities only in global form.

For example, once we make a payment or give a notice to the holder, we have no further responsibility for that payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect owners but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose — e.g., to amend the indenture for a series of debt securities or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture — we would seek the approval only from the holders, and not the indirect owners, of the relevant securities. Whether and how the holders contact the indirect owners is up to the holders.

When we refer to “you” in this section of the prospectus, we mean those who invest in the securities being offered by this prospectus, whether they are the holders or only indirect owners of those securities. When we refer to “your securities” in this section of the prospectus, we mean the securities in which you will hold a direct or indirect interest.

Special Considerations for Indirect Owners

If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

What Is a Global Security?

A global security is issued in book-entry form only. Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of one or more financial institutions or clearing systems, or their nominees, which we select. A financial institution or clearing system that we select for any security for this purpose is called the “depositary” for that security. A security will usually have only one depositary but it may have more.

Each series of these securities will have one or more of the following as the depositaries:

TABLE OF CONTENTS

The depositaries named above may also be participants in one another’s systems. Thus, for example, if DTC is the depositary for a global security, investors may hold beneficial interests in that security through Euroclear or Clearstream, as DTC participants. The depositary or depositaries for your securities will be named in your prospectus supplement; if none is named, the depositary will be DTC.

A global security may represent one or any other number of individual securities. Generally, all securities represented by the same global security will have the same terms. We may, however, issue a global security that represents multiple securities of the same kind, such as debt securities, that have different terms and are issued at different times. We call this kind of global security a master global security. Your prospectus supplement will indicate whether your securities are represented by a master global security.

A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated”. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only indirect interests in a global security. Indirect interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the security, but only an indirect owner of an interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. We describe the situations in which this can occur below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated”. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities

As an indirect owner, an investor’s rights relating to a global security will be governed by the account rules of the depositary and those of the investor’s financial institution or other intermediary through which it holds its interest (e.g., Euroclear or Clearstream, if DTC is the depositary), as well as general laws relating to securities transfers. We do not recognize this type of investor or any intermediary as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only in the form of a global security, an investor should be aware of the following:

Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated

If we issue any series of securities in book-entry form but we choose to give the beneficial owners of that series the right to obtain non-global securities, any beneficial owner entitled to obtain non-global securities may do so by following the applicable procedures of the depositary, any transfer agent or registrar for that series and that owner’s bank, broker or other financial institution through which that owner holds its beneficial interest in the securities. For example, in the case of a global security representing preferred shares or depositary shares, a beneficial owner will be entitled to obtain a non-global security representing its interest by making a written request to the transfer agent or other agent designated by us. If you are entitled to request a non-global certificate and wish to do so, you will need to allow sufficient lead time to enable us or our agent to prepare the requested certificate.

In addition, in a few special situations described below, a global security will be terminated and interests in it will be exchanged for certificates in non-global form representing the securities it represented. After that exchange, the choice of whether to hold the securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders. We have described the rights of holders and street name investors above under “— Who Is the Legal Owner of a Registered Security?”.

The special situations for termination of a global security are as follows:

If a global security is terminated, only the depositary, and not we or the trustee for any debt securities, is responsible for deciding the names of the institutions in whose names the securities represented by the global security will be registered and, therefore, who will be the holders of those securities.

Considerations Relating to Euroclear and Clearstream

Euroclear and Clearstream are securities clearance systems in Europe. Both systems clear and settle securities transactions between their participants through electronic, book-entry delivery of securities against payment.

Euroclear and Clearstream may be depositaries for a global security. In addition, if DTC is the depositary for a global security, Euroclear and Clearstream may hold interests in the global security as participants in DTC.

TABLE OF CONTENTS

As long as any global security is held by Euroclear or Clearstream, as depositary, you may hold an interest in the global security only through an organization that participates, directly or indirectly, in Euroclear or Clearstream. If Euroclear or Clearstream is the depositary for a global security and there is no depositary in the United States, you will not be able to hold interests in that global security through any securities clearance system in the United States.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the securities made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. We have no control over those systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on one hand, and participants in DTC, on the other hand, when DTC is the depositary, would also be subject to DTC’s rules and procedures.

Special Timing Considerations for Transactions in Euroclear and Clearstream

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than would be the case for transactions within one clearing system.

We will pay or allow distributors’ or sellers’ commissions that will not exceed those customary in the types of transactions involved. Broker-dealers may act as agents or may purchase securities as principal and thereafter resell the securities from time to time:

Offers to purchase securities may be solicited directly by us, or by agents designated by us, from time to time. Any such agent may be deemed to be an underwriter as that term is defined in the Securities Act. Any agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named in the applicable prospectus supplement, and any commissions payable by us to such agent will be set forth in the applicable prospectus supplement.

If we use an underwriter or underwriters in the offer and sale of securities under this prospectus and the accompanying prospectus supplement, we will execute an underwriting agreement with such underwriter(s) for the sale. The name(s) of such underwriter(s) and the terms of the transaction, including any underwriting discounts and other items constituting compensation of the underwriters and dealers, if any, will be set forth in such prospectus supplement, which will be used by the underwriter(s) to make resales of the securities under this prospectus and such prospectus supplement. The securities will be acquired by the underwriters for their own accounts and may be sold by the underwriters from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be

changed from time to time. We may grant underwriters who participate in the distribution of securities an option to purchase additional securities to cover over-allotments, if any, in connection with the distribution.

Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Unless otherwise described in an applicable prospectus supplement, the obligations of the underwriters to purchase offered securities will be subject to conditions, and the underwriters must purchase all of the offered securities if any are purchased.

In compliance with guidelines of the Financial Industry Regulatory Agency (FINRA), the maximum compensation or discount to be received by any participating FINRA members or independent broker dealers in connection with the offer and sale of any securities will not be greater than 8% of the aggregate amount of the securities offered pursuant to this prospectus and the applicable prospectus supplement.

We may sell directly to, and solicit offers from, institutional investors, individuals, or the public. We will describe the terms of any such sales in a prospectus supplement.

If we use a dealer in the sale of the securities under this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by the dealer at the time of resale. The name of the dealer and the terms of the transaction will be identified in the applicable prospectus supplement.

If an agent is used in an offering of securities being offered by this prospectus, the agent will be named, and the terms of the agency will be described, in the applicable prospectus supplement relating to the offering. Unless otherwise indicated in the prospectus supplement, an agent will act on a best efforts basis for the period of its appointment.

If indicated in the applicable prospectus supplement, we will authorize underwriters or their agents to solicit offers by certain institutional investors to purchase our securities pursuant to contracts providing for payment and delivery at a future date. Institutional investors with which these contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others. In all cases, these purchasers must be approved by us. The obligations of any purchaser under any of these contracts will not be subject to any conditions except that (a) the purchase of the securities must not at the time of delivery be prohibited under the laws of any jurisdiction to which that purchaser is subject and (b) if the securities are also being sold to underwriters, we must have sold to these underwriters the securities not subject to delayed delivery. Underwriters and other agents will not have any responsibility in respect of the validity or performance of these contracts.

Certain of the underwriters, dealers or agents used by us in any offering may be customers of, including borrowers from, engage in transactions with, and perform services for us or one or more of our affiliates in the ordinary course of business. Underwriters, dealers, agents and other persons may be entitled, under agreements which may be entered into with us, to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act. The terms of any indemnification provisions will be set forth in a prospectus supplement.

Until the distribution of the securities is completed, SEC rules may limit the ability of the underwriters and certain selling group members, if any, to bid for and purchase the securities. As an exception to these rules, the representatives of the underwriters, if any, are permitted to engage in certain transactions that stabilize the price of the securities in accordance with Regulation M under the Exchange Act but only in the case of a fixed-price offering. Such transactions may consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the securities.

If underwriters create a short position in the securities in connection with the offering thereof (i.e., if they sell more securities than are set forth on the cover page of the applicable prospectus supplement), the representatives of such underwriters may reduce that short position by purchasing securities in the open market. Any such representatives also may elect to reduce any short position by exercising all or part of any over-allotment option described in the applicable prospectus supplement.

TABLE OF CONTENTS

Any such representatives also may impose a penalty bid on certain underwriters and selling group members. This means that if the representatives purchase securities in the open market to reduce the underwriters’ short position or to stabilize the price of the securities, they may reclaim the amount of the selling concession from the underwriters and selling group members who sold those shares as part of the offering thereof.

In general, purchases of a security for the purpose of stabilization or to reduce a syndicate short position could cause the price of the security to be higher than it might otherwise be in the absence of such purchases. The imposition of a penalty bid might have an effect on the price of a security to the extent that it was to discourage resales of the security by purchasers in the offering.

Neither we nor any of the underwriters, if any, make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the securities. In addition, neither we nor any of the underwriters, if any, make any representation that the representatives of the underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

Each series of securities covered by this prospectus would be a new issue with no established trading market, other than our common stock which is listed on the New York Stock Exchange. Any shares of common stock sold pursuant to a prospectus supplement will be listed on the New York Stock Exchange or a stock exchange on which the common stock offered is then listed, subject (if applicable) to an official notice of issuance. Other than the common stock, the securities offered by this prospectus and any prospectus supplement may or may not be listed on a national securities exchange, a foreign securities exchange or eligible for quotation or trading on the New York Stock Exchange.

Any underwriters for whom securities are sold by us for public offering and sale may make a market in the securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, we cannot provide any assurance to you concerning the market for, or liquidity of, any of the securities covered by this prospectus and any prospectus supplement.

Under the securities laws of some states, the securities registered by the registration statement of which this prospectus forms a part may be sold in those states only through licensed brokers or dealers.

The anticipated date of delivery of the securities offered by this prospectus will be described in the applicable prospectus supplement relating to the offering.
