Prospectus summary

This summary highlights selected information from this prospectus, but may not contain all information that may be important to you. We urge you to read this entire prospectus carefully, including “Risk factors” and the consolidated financial statements and other information included or incorporated by reference herein.

PHI, INC.

PHI, Inc., founded in 1949, is a leading provider of commercial helicopter services. Our primary business is the safe and reliable transportation of personnel and, to a lesser extent, parts and equipment, to, from, and among offshore platforms for customers engaged in the oil and gas exploration, development, and production industry, principally in the Gulf of Mexico. We also provide helicopter services to the oil and gas industry internationally and to non-oil and gas customers and U.S. governmental agencies, such as the National Science Foundation. We also provide air medical transportation for hospitals and emergency service agencies where we operate as an independent provider of medical services. In addition, we perform maintenance and repair services for existing customers, primarily to those that own their own aircraft. As of September 30, 2010, we owned or operated 251 aircraft, 159 of which were dedicated to our Oil and Gas segment, 87 of which were dedicated to our Air Medical segment and five of which were dedicated to other operations.

Oil and Gas segment

We provide helicopter services to a broad base of major integrated and independent oil and gas companies, primarily in the Gulf of Mexico. Our key customers include Shell Oil Company (“Shell”), BP America Production Company (“BP”) and ConocoPhillips Company, with whom we have worked for 30 or more years, and Exxonmobil Production Co. and Eni Petroleum, with whom we have worked for more than 15 years. Our customers contract our services to transport personnel from onshore bases to offshore drilling rigs, platforms and other installations, to transport personnel during medical or safety emergencies and to evacuate personnel during the threat of hurricanes and other adverse weather conditions. In 2009, approximately 65% of our total operating revenues was generated by our Oil and Gas segment.

We generally classify our helicopters as small (up to six passengers), medium (up to 12 passengers) or large (up to 19 passengers), each of which serves a different transportation need of the offshore energy industry. Medium and large helicopters, which can fly in a wider variety of operating conditions, travel over longer distances and carry larger payloads than small helicopters, are required for crew changes on the large offshore production facilities and drilling rigs in the deepwater region of the Gulf of Mexico.

In 2004, we made a strategic decision to focus more of our business on these deepwater operations because we believed it would provide a stable and profitable source of revenue. Deepwater operations tend to have longer lead times and consequently, activity levels are less susceptible to short term volatility in commodity prices. The capital commitments are also substantially larger than shallow water operations and our client base is more heavily weighted to the major integrated and larger independent oil and gas companies as a result. Finally, the majority of our transportation activity services production facilities, which adds stability to our business as these are more permanent in nature.

Since we made the strategic decision to focus more of our business on deepwater activities, we have substantially increased our fleet of medium and large aircraft and reduced our fleet of light aircraft. We have added 26 medium aircraft and 16 large aircraft over that time, while selling 60 light aircraft and 25 older medium aircraft. As of October 31, 2010, of the 159 aircraft dedicated to our Oil and Gas segment, 74 were classified as medium or large.

We provide helicopter transportation services to some of the largest producers in the Gulf of Mexico, including Shell and BP. We recently entered in to a new contract to provide helicopter transportation services for Shell Offshore Inc., a subsidiary of Shell, and are in the process of acquiring 10 new medium aircraft to fulfill our obligations under that contract. See “Recent developments — New Shell contract.”

Building on our substantial expertise and track record of reliable and safe operations, we intend to selectively expand into international markets that have attractive opportunities for growth. We recently

1

executed an agreement to provide two aircraft to Noble Energy in support of its operations in Israel and are involved in discussions with TAM Empreendimentos e Participacoes S/A regarding the formation of a joint venture that would provide helicopter transportation services to the Brazilian oil and gas offshore market.

Air Medical segment

We provide air medical transportation services for hospitals and emergency service agencies in 17 states using approximately 87 aircraft at 60 separate locations. Our Air Medical segment operates primarily under the independent provider model and, to a lesser extent, under the hospital-based model. Under the independent provider model, we have no contracts and no fixed revenue stream, and compete for transport referrals on a daily basis with other operators in the area. Under the hospital-based model, we contract directly with the hospitals to provide their transportation services, with the contracts typically awarded on a competitive bid basis. Our Air Medical operations are headquartered in Phoenix, Arizona. We are paid directly by the hospital in the hospital-based model and by either commercial insurance companies, federal or state agencies such as Medicare and Medicaid, or the patient in the independent provider model. In 2009, approximately 33% of our total operating revenues was generated by our Air Medical segment.

Technical Services segment

The Technical Services segment provides helicopter repair and overhaul services for flight operations customers that own their aircraft. Costs associated with these services are primarily labor, and customers are generally billed at a percentage above cost. We also operate five aircraft for the National Science Foundation in Antarctica under this segment. Approximately 2% of our total operating revenues in 2009 was generated by our Technical Services segment.

BUSINESS STRATEGY

Our strategy is to grow our business while maximizing the profitability and cash flow of our existing operations. To achieve this objective, we intend to:

•  leverage our long-term customer relationships with major integrated energy companies and independent oil and gas producers to grow our business in the deepwater Gulf of Mexico;

•  protect our position in the Gulf of Mexico by maintaining our reputation as one of the safest and most reliable providers of helicopter transportation services;

•  pursue opportunities to grow our Oil & Gas segment in international markets, particularly in areas where the political risk is low and we can partner with reputable, well positioned parties;

•  pursue opportunities to grow our Air Medical operations in the hospital-based model, and selectively in the independent provider model where we believe demographics indicate a profitable patient transport volume; and

•  pursue attractive strategic acquisition opportunities.

COMPETITIVE STRENGTHS

We attribute our strong competitive position to a number of factors, including the following:

•  Leading market position.  We are a leading provider of commercial helicopter services in the oil and gas industry in the Gulf of Mexico, and our large operating scale and fleet size allow flexibility in scheduling helicopter services on a timely basis and over an extensive geographic area.

•  Long-term customer relationships.  We provide helicopter services to some of the largest producers of oil and gas in the Gulf of Mexico, including Shell and BP, two of the largest oil and gas producers in the Gulf of Mexico, with whom we have worked uninterrupted for more than 30 years. Our long-term relationships with many of our larger customers may present us with additional international opportunities where these customers operate.

•  Growing international presence.  We recently entered into an agreement to provide two aircraft to Noble Energy in support of its operations in Israel and are involved in discussions with TAM Empreendimentos e Participacoes S/A regarding the formation of a joint venture company that would provide helicopter transportation services to the expanding Brazilian oil and gas offshore market. Petrobras, Brazil’s leading oil and gas exploration company and one of the largest offshore operators in the world, has announced an aggressive offshore development plan, which should provide a high level of demand for our services. We believe that partnering with a local, well-respected company such as TAM Empreendimentos e Participacoes S/A would provide us with a competitive advantage in the Brazilian market. We currently operate one aircraft in the Democratic Republic of Congo. We also operate five aircraft in Antarctica for the National Science Foundation.

•  Operational enhancements.  Since 2001, we have made operational enhancements to our business, including substantial investments in new facilities, upgrades of our computer systems and software, the

3

refurbishment of our fleet and the implementation of a significant cost reduction program. In addition, we have sold helicopters that were not profitable or that did not complement our existing fleet, terminated or declined to renew lower margin contracts and steadily increased our rates. As a result of these changes, we are well positioned to expand our business and to capitalize on opportunities in our industry.

•  Large, modern, well-maintained fleet.  We believe that our existing fleet is among the most modern and best maintained aircraft fleet operating in the Gulf of Mexico. We believe our fleet is at least 50% larger than our next largest competitor in the Gulf of Mexico. We target a complete, full-scale refurbishment in our repair and maintenance facility every five years for each of our Oil and Gas aircraft to maintain our level of quality. As required by the FAA, we routinely inspect our aircraft in accordance with manufacturer specifications.

•  Integrated operation and maintenance functions.  We believe that we are one of the industry leaders in helicopter maintenance, repair and refurbishment operations. We also believe that our repair and refurbishment facility in Lafayette, Louisiana, which became operational in 2001, is one of the premier facilities of its kind in the world due to its size, scope of operations, extensive inventory of parts and experienced technical and maintenance personnel. We believe this facility allows us to more efficiently and effectively service our fleet of aircraft, resulting in less downtime and safer operations.

•  Strong safety record; experienced and extensively trained pilots.  Safety is critical to us and to our customers. Our pilots average nearly 7,000 hours of flight time and 11 years of experience with PHI, and must have at least 1,500 flight hours and a commercial pilot certificate with instrument rating before we hire them. Once hired, our pilots undergo rigorous additional training covering all aspects of helicopter operation. As a result of this training and experience, coupled with our detailed safety maintenance system and comprehensive maintenance, we believe that we have one of the best safety records in the industry. Based on data compiled by the Helicopter Safety Advisory Conference, for the five-year period through 2009, our Gulf of Mexico operations averaged 0.54 accidents for each 100,000 flight hours, approximately two-thirds less than the average rate for our Gulf of Mexico competitors (1.58 accidents per 100,000 flight hours). According to the National Transportation Safety Board, for the ten-year period through 2009, on a company-wide basis, our accident rate was 1.66 accidents per 100,000 flight hours, compared to a national average rate of 7.12 accidents per 100,000 flight hours.

•  Significant barriers to entry to serve our larger customers.  We believe that there are significant barriers to entry in our industry, particularly with respect to operating aircraft for the major oil companies and the larger independent oil companies. Our largest customers have employees dedicated to setting extensive selection criteria for their helicopter transport provider. These criteria are based on safety and performance records, and very few companies have the substantial infrastructure and track record to meet these stringent requirements. Operators who are unable to meet these rigorous quality standards on a long-term basis generally are excluded from the bidding process. We work closely with our customers to meet their specific requirements. In addition, our primary targets for growth in the air medical industry are currently served by a limited number of major competitors.

•  Experienced management and operations team.  Members of our senior management and operations team have significant experience in the oil and gas service industry and in the commercial helicopter service industry. Al A. Gonsoulin, our Chairman of the Board and Chief Executive Officer, has over 40 years of experience in the oil and gas service industry. The nine members of our senior management team, excluding the Air Medical segment, average approximately 15 years of service with us and have an average of approximately 27 years of aviation experience. David Motzkin, the director of our Air Medical operations, and his four regional directors have an aggregate of approximately 75 years of experience in the emergency medical services industry.

INDUSTRY OVERVIEW

Gulf of Mexico helicopter operations

Offshore oil and gas activities in the Gulf of Mexico require daily movement of several thousand people plus parts and equipment between onshore bases and remote offshore working areas. These transports must occur in a safe, timely manner to ensure smooth operations and avoid costly delays. Helicopters are a primary means of offshore transportation, particularly for crew changes, and typically are the only economical crew transportation option for distances greater than 60 miles from shore. The outermost portions of the continental shelf region of the Gulf of Mexico (the “Continental Shelf”) are located approximately 85 miles from our 17 onshore bases in Louisiana, Texas and Alabama, and the deepwater areas generally are located from 170 to 230 miles from these bases, which allow us to efficiently service the primary exploration and production areas of the Gulf of Mexico.

Crews working offshore typically work on a seven days on, seven days off or a 14 days on, 14 days off basis, with crew changes generally occurring midweek at regularly scheduled times. The size of a crew working at any given time is approximately 60 to 90 people for a jackup rig in the Continental Shelf and 100 to 200 or more people for the larger drilling rigs and production facilities involved in deepwater drilling and production. Typically, there are two crews working onsite at any given time, with one crew being changed out each week. Because of the size of crew complements offshore, multiple round trips or multiple helicopters are required for each crew change operation.

Demand for helicopter services in the Gulf of Mexico is driven by the number of production facilities (both manned and unmanned) and drilling rigs. As of September 10, 2010, there are approximately 3,400 active oil and gas platforms and 109 contracted offshore drilling rigs in the Gulf of Mexico.

The majority of the 3,400 active oil and gas platforms are located on the Continental Shelf of the Gulf of Mexico and must be inspected and maintained on a regular basis by both operators and regulatory officials to satisfy regulatory and operator safety requirements. These ongoing inspection and maintenance services provide a stable level of helicopter demand that generally is less sensitive to short-term changes in commodity prices. Light helicopters are the most efficient way to service these maintenance and inspection visits and smaller crew changes.

The U.S. Gulf of Mexico, particularly its deepwater region, is an increasingly important source of oil and natural gas production, as it is one of the last known sources of large deposits of oil and natural gas in the U.S. Currently, according to the Bureau of Ocean Energy Management, Regulation, and Enforcement, there are approximately 2,200 active leases in water depths less than 200 meters, and approximately 4,400 active leases beyond that water depth, including approximately 3,500 active leases in water depths greater than 1,000 meters. According to Wood Mackenzie, an international energy research firm, as of September 7, 2010, there are 48 deepwater fixed production platforms and floating production facilities in service in the Gulf of Mexico, and an additional 11 deepwater platforms and facilities have been identified for development in the Gulf of Mexico between 2010 and 2016.

Air Medical operations

The civilian air medical industry began in the 1970s and has grown steadily since that time. According to the Association of Air Medical Services, the number of air transports has grown at a 7% compound annual growth rate (“CAGR”) since 1990 and at an 11.5% CAGR since 2000, while the number of aircraft has grown at a CAGR of 11% since 1990 and 18.3% since 2000. Patient transports can be from one medical facility to another or from an accident scene to a medical facility.

The entire air medical transportation market in the U.S. is approximately $2.5 billion, of which about 50%, or $1.2 billion, is controlled by hospitals. In recent years, hospitals gradually have begun to exit this market, which is expected to increase the portion of the market available to independent operators over the next several years. As hospitals exit the market, PHI has begun shifting its focus to the hospital-based model by providing air medical services to those hospitals that no longer desire to operate air medical operation themselves, which we believe will increase the stability of our revenue from the Air Medical segment. Under this model, the hospital

5

pays us a fixed monthly base rate and a variable rate per flight hour. In contrast, under the independent provider model, we provide not only the transportation, but also the medical care, communications and dispatch, and billing and collections. Our revenues under this model are variable and consist of flight fees billed directly to patients, their insurers or to governmental agencies such as Medicare and Medicaid.

SAFETY RECORD

Our customers consistently cite safety and reliability as a critical factor in selecting a provider of air transportation services. Since our inception in 1949, safety has been a top priority and one of the cornerstones of our culture. In over 50 years of operations, we have logged more than 10.5 million flight hours, and during that time we have developed and refined rigorous safety programs and practices that we believe have given us one of the strongest safety records in the commercial helicopter industry.

We believe that the key elements of our strong safety record are awareness, extensive training, employee incentives and comprehensive maintenance of our fleet. We strive to incorporate best safety practices in every area of our operations. Our company-wide safety program rewards employees who contribute to our safety goals by working accident free, and we believe our pilots and mechanics are among the most experienced and well trained in the industry.

Based on data compiled by the Helicopter Safety Advisory Conference, for the five-year period through 2009, our Gulf of Mexico operations averaged 0.54 accidents for each 100,000 flight hours, approximately two-thirds less than the average rate for our Gulf of Mexico competitors (1.58 accidents per 100,000 flight hours). According to the National Transportation Safety Board, for the ten-year period through 2009, on a company-wide basis, our accident rate was 1.66 accidents per 100,000 flight hours, compared to a national average rate of 7.12 accidents per 100,000 flight hours.

RECENT DEVELOPMENTS

Financing transactions

On September 23, 2010, we issued an aggregate principal amount of $300 million of 8.625% Senior Notes due 2018 in private placements, of which $297 million was issued to UBS Securities LLC, as the initial purchaser, in connection with transactions under Rule 144A and Regulation S of the Securities Act, and $3 million was issued to two accredited investors pursuant to Regulation D of the Securities Act. Net proceeds of $295.5 million were used to repurchase $189.5 million of our $200 million outstanding 7.125% Senior Notes due 2013 pursuant to a tender offer that also settled on September 23, 2010, at a total cost of $199.0 million, including the tender premium and accrued and unpaid interest. On October 25, 2010, we redeemed the remaining $10.5 million of 7.125% notes outstanding, at a redemption price of 103.563% of their face amount plus accrued and unpaid interest. After the repurchase and redemption of all of our outstanding $200 million 7.125% Senior Notes as described above, we had remaining net proceeds of approximately $82.0 million. We intend to use these proceeds for general corporate purposes, including the exercise of purchase options for aircraft currently leased, and for the purchase of aircraft required to perform our new contract with Shell described below. Of the approximately $82.0 million in net proceeds, on October 1, 2010, $25.3 million was used for the purchase of aircraft off lease.

Options to purchase leased aircraft

As of September 30, 2010, we had options to purchase aircraft under lease becoming exercisable in 2010 through 2014 for the following aggregate purchase prices, respectively: $25.3 million, $54.3 million, $51.0 million, $38.8 million and $114.4 million. Subject to market conditions, we intend to exercise these options as they become exercisable, and intend to finance some of these acquisition costs with the net proceeds of our 2018 notes. On October 1, 2010, we exercised the options exercisable in 2010, acquiring two heavy aircraft for $25.3 million, funded with the proceeds of the 2018 notes.

New Shell contract

In 2010, we executed a new contract with Shell Offshore, Inc., a subsidiary of Shell, to provide helicopter transportation services in the Gulf of Mexico through mid-2016. The contract covers 11 aircraft, and requires us to replace, between June 2011 and January 2013, the Sikorsky S-76 aircraft we currently provide to Shell

6

with 10 Agusta Westland AW139’s, a more costly aircraft which commands a higher rate. We believe this contract reinforces our strong relationship with Shell, who is one of our largest customers, having contributed 15% of our consolidated revenues in 2009.

In connection with the new Shell contract, we have entered into a contract to acquire 10 new Augusta Westland AW139 aircraft, scheduled for delivery commencing in late 2010 and continuing through late 2012. The AW139s have an aggregate acquisition cost of approximately $127 million. We have traded in two aircraft in exchange for a credit of approximately $20.3 million towards these acquisition costs. We may finance some of these acquisition costs with net proceeds from the issuance of the 2018 notes and expect to finance the balance through some combination of cash on hand or generated from operations, operating leases and borrowings under our revolving credit facility.

The Macondo incident

In April 2010, the Deepwater Horizon rig, engaged in deepwater drilling operations at BP’s Macondo well in the Gulf of Mexico, sank after a blowout, resulting in the discharge of substantial amounts of oil until mid-July 2010, when the flow of oil was stopped. On May 28, 2010, the Department of Interior imposed a six-month moratorium on offshore deepwater drilling operations, the enforcement of which was preliminarily enjoined, and on July 12, 2010, the Department of Interior imposed another similar moratorium set to expire November 30, 2010. As a result, deepwater drilling operations in the Gulf of Mexico were suspended. On October 12, 2010, the Department of Interior lifted the moratorium on deepwater drilling. In addition, as a result of regulatory actions by the Department of Interior, there has been a “de facto” moratorium on drilling in the shallow waters of the Gulf of Mexico. It is not possible to estimate whether or when drilling operations in the Gulf of Mexico will return to normal activity levels, due to uncertainties surrounding the timing of issuance of drilling permits by the Department of Interior and new regulations related to drilling operations. BP has incurred significant costs related to the clean up of and damages caused by the oil spill and stopping the flow of oil from the well. BP is one of our major customers and accounted for approximately 14% of our total revenues in 2009.

As a result of these events, we have experienced increased flight activity, although we expect that this increased activity will decline when flight activity associated with the clean-up winds down. We estimate that the flight hours related to this increased activity were approximately 2,800 hours and 1800 hours, or 7% and 5% of total flight hours (9% and 6% of Oil and Gas segment flight hours) for the second and third quarters of 2010, respectively. Offsetting these increased flight hours are decreased flight hours resulting from the suspension of deepwater drilling activities in the Gulf of Mexico. We estimate that the adverse affect to our flight hours related to deepwater drilling rigs that have already demobilized are approximately 500 to 600 flight hours per month, or approximately 5% of Oil and Gas segment flight hours per month. Many of the deepwater drilling rigs we have been servicing are still on location (although not drilling), and therefore we are still conducting crew changes to those rigs. It is not possible to estimate how long these rigs will remain in their current status, but if these drilling rigs are demobilized or leave the Gulf of Mexico, there will be a further adverse affect to our flight activity. The majority of our transportation activity services production facilities, which were not directly impacted by the moratorium. This adds stability to our business as these are more permanent in nature.

While the Macondo incident presents risks to our business, we believe it also presents opportunities. Increased regulatory requirements that may result from the incident could give a competitive advantage to our customers, who tend to be larger operators and we believe better able to absorb related increased costs. We also believe that an increased focus on safety could benefit our company, as we have a strong record of safe operations. For a discussion of risks to our business from the Macondo incident, see “Risk factors.”

Change of control	Upon certain “Change of Control” events (as defined in the indenture), each holder of notes may require us to repurchase all or a portion of its notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. See “Description of the notes — Change of control.”
Certain covenants	The indenture governing the notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:
	• incur additional indebtedness and issue certain capital stock;
	• pay dividends on, redeem or repurchase capital stock;
	• make investments;
	• sell assets;
	• engage in transactions with affiliates;
	• enter into agreements that restrict dividends or other payments from our restricted subsidiaries to us;
	• enter into different lines of business;
	• create unrestricted subsidiaries;
	• enter into sale and leaseback transactions;
	• create liens on our assets; and
	• consolidate, merge or transfer all or substantially all of our assets and the assets of our restricted subsidiaries on a consolidated basis.
	These covenants are subject to important exceptions and qualifications, which are described in “Description of the notes.” Many of the covenants will be suspended during any period when the notes have an investment grade rating from the rating agencies as described under “Description of the notes — Certain covenants.”
Use of proceeds	We will not receive any proceeds from the notes offered by selling noteholders under this prospectus. See “Use of proceeds.”

Risk factors

Investing in the notes involves risks. You should carefully consider the risks described below as well as those risks contained in Item 1A “Risk factors” in our Annual Report on Form 10-K for the year ended December 31, 2009 and Quarterly Reports on Form 10-Q for the periods ended March 31, 2010, June 30, 2010 and September 30, 2010, respectively, which are incorporated into this prospectus by reference, together with all other information and data included or incorporated by reference in this prospectus, before making an investment decision. Additional risks and uncertainties not currently known to us or that we consider to be immaterial may also materially impact our business, operations or financial condition. Any of the following risks could impair our business, financial condition or operating results. This could cause you to lose all or part of your investment in the notes.

RISKS RELATING TO THE NOTES

Our substantial indebtedness and operating lease commitments could adversely affect our financial condition and impair our ability to operate our business.

We are a highly leveraged company and, as a result, have significant debt service obligations. We also have significant operating lease commitments and, as a result, have significant rent expense. As of September 30, 2010, our total indebtedness was $318.3 million, consisting of $300 million of our 2018 notes and $18.3 million borrowed under our revolving credit facility, which matures in September 2012, excluding $5.5 million in letters of credit issued under the revolving credit facility. As of September 30, 2010, the amount available for borrowing under the revolving credit facility was $51.2 million. Borrowings under our revolving credit facility are secured by accounts receivable and inventory and are effectively senior to our 2018 notes and the notes offered hereby to the extent of the value of the assets securing such borrowings. As of September 30, 2010, our ratio of total long-term indebtedness to shareholders’ equity was .67 to 1.00.

As of September 30, 2010, we had approximately $207.0 million in aggregate commitments under operating leases, of which approximately $8.2 million is payable through December 31, 2010, and a total of $33.3 million is payable in 2011. The total lease commitments include $190.7 million for aircraft and $16.3 million for facility lease commitments, primarily for our facilities in Lafayette, Louisiana.

We could incur additional debt and enter into additional operating leases, which could negatively impact our financial condition, results of operations and business prospects and prevent us from satisfying our obligations under the notes.

The degree to which we are leveraged or may become leveraged in the future could have important consequences to you, including:

•  we will be required to dedicate a substantial portion of our cash flow from operations to pay principal of, and interest on, our indebtedness, and make lease payments on our operating leases, thereby reducing funds available for operations, working capital, capital expenditures, expansion, acquisitions or general corporate or other purposes or to carry out other aspects of our business plan;

•  it may increase our vulnerability to a downturn in our business that may result from the Macondo incident or for other reasons;

•  it may increase our vulnerability to general adverse economic and industry conditions and limit our ability to withstand competitive pressures;

•  we may be more highly leveraged than our competitors, which may place us at a competitive disadvantage;

•  our ability to obtain additional financing in the future may be impaired;

•  it may limit, along with the financial and other restrictive covenants in our revolving credit facility and future indebtedness, among other things, our ability to borrow additional funds or dispose of assets;

•  our flexibility in planning for, or reacting to, changes in our business and industry may be limited; and

•  it may make it more difficult for us to satisfy our obligations with respect to the notes.

10

The occurrence of any one of these events could have a material adverse effect on our business, financial condition, results of operations, business prospects and ability to satisfy our obligations under the notes.

Our ability to meet our debt obligations, lease commitments and other expenses will depend on our future performance, which will be affected by financial, business, economic, regulatory and other factors, many of which we are unable to control.

In the event of our bankruptcy or liquidation, holders of the notes will be paid from any assets remaining after payments to any holders of secured debt and debt and other liabilities of our non-guarantor subsidiaries.

The notes and the guarantees are general unsecured senior obligations of us and our subsidiary guarantors, effectively junior to any of our existing or future secured debt to the extent of the value of assets securing that debt. The notes and the guarantees are effectively subordinated to the indebtedness and other liabilities of our non-guarantor subsidiaries. If we are declared bankrupt or insolvent, or are liquidated, holders of our secured debt and any secured debt of our subsidiaries will be entitled to be paid from our assets before any payment may be made with respect to the notes. In addition, in that circumstance, holders of debt and other creditors of our non-guarantor subsidiaries would be entitled to be paid from the assets of those subsidiaries before the proceeds of those assets could be applied to pay the notes. If any of the foregoing events occurs, we cannot assure you that we will have sufficient assets to pay amounts due on our secured debt, the secured debt of our subsidiary guarantors, the debt and other liabilities of our non-guarantor subsidiaries, and the notes and other liabilities of us and our subsidiaries. As a result, holders of the notes may receive less, ratably, than holders of secured debt of us or our subsidiary guarantors or the debt of our non-guarantor subsidiaries in the event of bankruptcy or liquidation.

We may not be able to generate cash flow to meet our service obligations.

Our ability to make payments on our indebtedness, including the notes, to pay our obligations under our operating leases, and to fund planned capital expenditures, including purchases of aircraft under purchase options, will depend on our ability to generate cash in the future. This is subject to conditions in the oil and gas industry, particularly in the Gulf of Mexico, and to general economic and financial conditions, the impact of legislative and regulatory actions on how we conduct our business and other factors, all of which are beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations to service our outstanding indebtedness or to pay our obligations under operating leases, or that future borrowings or access to aircraft lease facilities will be available to us in an amount sufficient to enable us to pay our indebtedness or to fund our other capital needs, such as purchases of aircraft under purchase options or upon expiration of operating leases. If our business does not generate sufficient cash flow from operations to service our outstanding indebtedness or to pay our operating lease operations, we may have to undertake alternative financing plans, such as:

•  refinancing or restructuring our debt;

•  selling assets;

•  reducing or delaying acquisitions or capital investments; or

•  seeking to raise additional capital.

However, we cannot assure you that we would be able to implement alternative financing plans, if necessary, on commercially reasonable terms or at all, or that implementing any such alternative financing plans would allow us to meet our debt obligations and capital investment needs. Our inability to generate sufficient cash flow to satisfy our debt and operating lease obligations, including our obligations under the notes, or to obtain alternative financings, could materially and adversely affect our business, financial condition, results of operations and prospects.

11

Restrictions in our debt agreements could limit our growth and our ability to respond to changing conditions.

Our revolving credit facility contains and the indenture governing the notes contain a number of significant covenants in addition to covenants restricting the incurrence of additional debt. These covenants limit our ability, among other things, to:

•  pay cash dividends or distributions on our capital stock or redeem or repurchase our capital stock;

•  make certain investments;

•  create certain liens on our assets to secure debt;

•  consolidate, merge or enter into other business combination transactions;

•  issue and sell capital stock of our subsidiaries;

•  incur additional indebtedness and issue certain capital stock;

•  enter into different lines of business;

•  enter into agreements that restrict dividends or other payments from our subsidiaries to us;

•  participate in activities through business entities that are not subsidiaries;

•  enter into sale and leaseback transactions;

•  enter into certain transactions with affiliates; and

•  transfer and sell assets.

In addition, our revolving credit facility requires us to maintain certain financial ratios and satisfy certain financial condition tests and may require us to take action to reduce our debt or take some other action to comply with them. These restrictions could also limit our ability to obtain future financings, make needed capital expenditures, withstand a future downturn in our business or the economy in general, or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants under our revolving credit facility and the indenture impose on us.

A breach of any of these covenants would result in a default under the applicable debt agreement. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and acceleration of, the debt outstanding under the other debt agreements. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us. See “Description of the notes — Events of default.”

We may not be able to repurchase the notes or repay debt under our revolving credit facility upon a change of control.

Upon the occurrence of a change of control, holders of the notes may require us to offer to repurchase all or any part of their notes. We may not have sufficient funds at the time of the change of control to make the required repurchases, or restrictions under our revolving credit facility may not allow such repurchases. Additionally, an event constituting a “Change of Control” (as defined in the indenture) will likely be an event of default under our revolving credit facility if we are required to offer to repurchase the notes but are unable to do so, which default would, if it should occur, permit the lenders to accelerate the debt outstanding under our revolving credit facility and that, in turn, would cause an event of default under the indenture.

The source of funds for any repurchase required as a result of any change of control will be our available cash or cash generated from operations or other sources, including borrowings, sales of assets, sales of equity or funds provided by a new controlling entity. We cannot assure you, however, that sufficient funds would be available at the time of any change of control to make any required repurchases of the notes tendered and to

12

repay debt under our revolving credit facility. Furthermore, using available cash to fund the potential consequences of a change of control may impair our ability to obtain additional financing in the future. Any of our future credit agreements or other agreements relating to debt will most likely contain similar restrictions and provisions.

Not all of our subsidiaries guarantee the notes.

Our foreign subsidiaries do not guarantee the notes. Although our non-guarantor subsidiaries generated no or de minimis revenues and operating cash flow during the twelve-month period ended December 31, 2009 and nine months ended September 30, 2010, and these subsidiaries had de minimis assets and liabilities and no indebtedness (other than intercompany debt) as of September 30, 2010, these non-guarantor subsidiaries may have revenues, operating cash flow, assets, liabilities and indebtedness in the future, in which case the claims of creditors of such non-guarantor subsidiaries, including trade creditors and creditors holding indebtedness, and claims of preferred stockholders (if any) of such subsidiaries will generally have priority with respect to the assets and earnings of such subsidiaries over the claims of creditors of our company, including holders of the notes, even if the obligations of the non-guarantor subsidiaries do not constitute senior indebtedness.

The subsidiary guarantees could be deemed fraudulent conveyances under certain circumstances, and a court may subordinate or void the subsidiary guarantees.

Under various fraudulent conveyance or fraudulent transfer laws, a court could subordinate or void the subsidiary guarantees. Generally, to the extent that a U.S. court were to find that at the time one of our subsidiaries entered into a subsidiary guarantee either:

•  the subsidiary incurred the guarantee with the intent to hinder, delay or defraud any present or future creditor, or contemplated insolvency with a design to favor one or more creditors to the exclusion of others; or

•  the subsidiary did not receive fair consideration or reasonably equivalent value for issuing the subsidiary guarantee and, at the time it issued the subsidiary guarantee, the subsidiary

•  was insolvent or became insolvent as a result of issuing the subsidiary guarantee,

•  was engaged or about to engage in a business or transaction for which the remaining assets of the subsidiary constituted unreasonably small capital, or

•  intended to incur, or believed that it would incur, debts beyond its ability to pay those debts as they matured, then the court could void or subordinate the subsidiary guarantee in favor of the subsidiary’s other obligations.

A legal challenge of a subsidiary guarantee on fraudulent conveyance grounds may focus, among other things, on the benefits, if any, the subsidiary realized as a result of our issuing the notes. To the extent a subsidiary guarantee is voided as a fraudulent conveyance or held unenforceable for any other reason, the holders of the notes would not have any claim against that subsidiary and would be creditors solely of us and any other subsidiary guarantors whose guarantees are not held unenforceable.

Your ability to sell the notes may be limited by the absence of an active trading market, and there is no assurance that an active trading market will develop for the notes.

There is no established public market for the notes. We do not presently intend to apply for listing of the notes on any securities exchange. We cannot assure you that an active market for the notes will develop or, if developed, that it will continue. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. We cannot assure you that the market, if any, for the notes will be free from similar disruptions or that any such disruptions may not adversely affect the prices at which you may sell your notes. In addition, subsequent to their initial issuance, the notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our performance and other factors.

RISKS INHERENT IN OUR BUSINESS

The failure to maintain our safety record would seriously harm our ability to attract new customers and maintain our existing customers.

A favorable safety record is one of the primary factors a customer reviews in selecting an aviation provider. If we fail to maintain our safety and reliability record, our ability to attract new customers and maintain our current customers will be materially adversely affected.

Helicopter operations involve risks that may not be covered by our insurance or may increase the cost of our insurance.

The operation of helicopters inherently involves a high degree of risk. Hazards such as aircraft accidents, collisions, fire and adverse weather are hazards that must be managed by providers of helicopter services and may result in loss of life, serious injury to employees and third parties, and losses of equipment and revenues.

We maintain hull and liability insurance on our aircraft, which insures us against physical loss of, or damage to, our aircraft and against certain legal liabilities to others. In addition, we carry war risk, expropriation, confiscation and nationalization insurance for our aircraft involved in international operations. In some instances, we are covered by indemnity agreements from our customers in lieu of, or in addition to, our insurance. Our aircraft are not insured for loss of use.

While we believe that our insurance and indemnification arrangements provide reasonable protection for most foreseeable losses, they do not cover all potential losses and are subject to deductibles, retentions, coverage limits and coverage exceptions such that severe casualty losses, or the expropriation or confiscation of significant assets could materially and adversely affect our financial condition or results of operations. The occurrence of an event that is not fully covered by insurance could have a material adverse impact on our financial condition, results of operations, and cash flows.

Our operations are affected by adverse weather conditions and seasonal factors.

We are subject to three types of weather-related or seasonal factors:

•  poor weather conditions that often prevail during winter but can develop in any season;

•  the tropical storm and hurricane season in the Gulf of Mexico; and

•  reduced daylight hours during the winter months.

Poor visibility, high winds and heavy precipitation can affect the operation of helicopters and significantly reduce our flight hours. A significant portion of our operating revenue is dependent on actual flight hours and a substantial portion of our direct costs is fixed. Thus, prolonged periods of adverse weather can materially and adversely affect our operating revenues and net earnings.

In the Gulf of Mexico, the months of December, January and February generally have more days of adverse weather conditions than the other months of the year. Also, June through November is tropical storm and hurricane season in the Gulf of Mexico, with August and September typically being the most active months. During tropical storms, we are unable to operate in the area of the storm and can incur significant expense in moving our aircraft to safer locations. In addition, as most of our facilities are located along the Gulf of Mexico coast, tropical storms and hurricanes may cause substantial damage to our property, including helicopters that we are unable to relocate.

Because the fall and winter months have fewer hours of daylight, our flight hours are generally lower at those times, which typically results in a reduction in operating revenues during those months. Currently, only 88 of the 159 helicopters used in our oil and gas operations are equipped to fly under IFR, which enables these aircraft, when manned by IFR-rated pilots and co-pilots, to operate when poor visibility or darkness prevents flight by aircraft that can fly only under VFR. Not all of our pilots are IFR rated.

14

Our helicopters may not always be profitably deployed.

Management of our helicopter fleet exposes us to the risk that our helicopters may not always be profitably deployed. Customers often require a specific type of helicopter, which may be different from those in our fleet. Our contract terms generally are too short to recover our cost of purchasing a helicopter, subjecting us to the risk that we will be unable to recoup our investment in the helicopter. Helicopters we acquire may not be covered by customer contracts when they are placed into service. Once a new helicopter is delivered to us, we generally spend between two and three months installing mission-specific and/or customer-specific equipment before we place it into service. As a result, there can be a significant delay between the delivery date for a new helicopter and the time that it is able to generate revenues for us.

We may not be able to find alternative profitable uses for helicopters no longer under contract. For example, in the third quarter of 2010, we entered into a contract to purchase 10 medium aircraft related to requirements under a new contract with a customer, which will replace aircraft being used with respect to the current contract over a two-year period. See “Prospectus summary — Recent developments — New Shell contract.” As a result, we must find alternative profitable uses for the helicopters that will be released under the current contract. If we cannot find an acceptably profitable use for a helicopter, or if a helicopter no longer meets our strategic objectives, including due to age, we may sell it. Prices in the used helicopter market have been volatile over time, and we may incur gains or losses from the sale of helicopters. Inability to profitably deploy helicopters in our fleet may have a material adverse effect on our financial condition, results of operation and cash flow.

Our contracts generally can be terminated or downsized by our customers without penalty.

Most of our fixed-term contracts contain provisions permitting early termination by the customer, sometimes with as little as 30 days’ notice for any reason and generally without penalty. In addition, many of our contracts permit our customers to decrease the number of aircraft under contract with a corresponding decrease in the fixed monthly payments without penalty. As a result, undue reliance should not be placed on our customer contracts or the terms of those contracts.

The helicopter services business is highly competitive.

All segments of our business are highly competitive. Many of our contracts are awarded after competitive bidding, and the competition for those contracts generally is intense. The principal aspects of competition are safety, price, reliability, availability and service.

We have two major competitors and several small competitors operating in the Gulf of Mexico, and most of our customers and potential customers could operate their own helicopter fleets if they chose to do so.

Our Air Medical segment competes for business primarily under the independent provider model and, to a lesser extent, under the hospital-based model. Under the independent provider model, we have no contracts and no fixed revenue stream, but must compete for transport referrals on a daily basis with other independent operators in the area. Under the hospital-based model, we contract directly with the hospital to provide their transportation services, with the contracts typically awarded on a competitive bid basis. Under both models, we compete against national and regional companies, and there is usually more than one competitor in each local market. In addition, we compete against hospitals that operate their own helicopters and, in some cases, against ground ambulances as well.

Our air medical operations expose us to numerous special risks, including collection risks and potential medical malpractice claims.

Our air medical operations are highly competitive and expose us to a number of risks that we do not encounter in our oil and gas operations. For instance, the fees for our air medical services generally are paid by individual patients, insurance companies, or government agencies such as Medicare and Medicaid. As a result, our profitability in this business depends not only on our ability to generate an acceptable volume of

15

patient transports, but also on our ability to collect our transport fees. We are not permitted to refuse service to patients based on their inability to pay.

We employ paramedics, nurses, and other medical professionals for these operations, which can give rise to medical malpractice claims against us, which, if not fully covered by our medical malpractice insurance, could materially adversely affect our financial condition and results of operations.

Increased governmental regulations could increase our costs or reduce our ability to operate successfully.

Our operations are regulated by a number of federal and state agencies. All of our flight operations are regulated by the FAA. Aircraft accidents are subject to the jurisdiction of the National Transportation Safety Board. Standards relating to workplace health and safety are monitored by OSHA. We are also subject to various federal and state healthcare-related laws and regulations.

The FAA has jurisdiction over many aspects of our business, including personnel, aircraft and ground facilities. We are required to have an Air Taxi Certificate, granted by the FAA, to transport personnel and property in our helicopters. This certificate contains operating specifications that allow us to conduct our present operations, but it is potentially subject to amendment, suspension or revocation in accordance with procedures set forth in the Federal Aviation Act. The FAA conducts regular inspections regarding the safety, training and general regulatory compliance of our U.S. aviation operations. Additionally, the FAA requires us to file reports confirming our continued compliance.

FAA regulations require that at least 75% of our voting securities be owned or controlled by citizens of the U.S. or one of its possessions, and that our president and at least two-thirds of our directors be U.S. citizens. Our Chief Executive Officer and all of our directors are U.S. citizens, and our organizational documents provide for the automatic reduction in voting power of each share of voting common stock owned or controlled by a non-U.S. citizen if necessary to comply with these regulations.

We are subject to significant regulatory oversight by OSHA and similar state agencies. We are also subject to the Communications Act of 1934 because of our ownership and operation of a radio communications flight-following network throughout the Gulf of Mexico.

Numerous other federal statutes and rules regulate our offshore operations and those of our customers, pursuant to which the federal government has the ability to suspend, curtail or modify certain or all offshore operations. A suspension or substantial curtailment of offshore oil and gas operations for any prolonged period would have an immediate and materially adverse effect on us. A substantial modification of current offshore operations could adversely affect the economics of such operations and result in reduced demand for our services.

Our air medical operations are also subject to healthcare-related laws and regulations, including those related to Medicare and Medicaid compliance and the privacy and security rules of the Health Insurance Portability and Accountability Act of 1996, as amended.

Our operations are subject to stringent and comprehensive environmental laws and regulations that may expose us to significant costs and liabilities.

Our operations are subject to stringent laws and regulations relating to environmental protection. Inherent in our business is the risk of incurring significant environmental costs and liabilities due to our handling of petroleum products and generated wastes, because of air emissions and wastewater discharges related to our operations, and as a result of historical operations and waste disposal practices. Environmental laws and regulations generally require us to obtain permits such as air emissions and wastewater permits before regulated activities commence, require us to remain in compliance with the permits, restrict the types, quantities and concentration of materials that can be released into the environment in connection with regulated activities, and impose substantial liabilities for pollution resulting from operations. Failure to comply with these laws and regulations or the terms or conditions of required environmental permits may result in the assessment of administrative, civil and/or criminal penalties, the imposition of remedial obligations or corrective actions, and the issuance of injunctions limiting or prohibiting some or all of our operations.

16

We currently own or lease, and have in the past owned or leased, properties that have been used for many years by persons, including us, for various aviation operational support and maintenance activities. Petroleum products and wastes may have been disposed or released on or under properties owned or leased by us or on or under other locations where we have arranged for such petroleum products or wastes to be taken for disposal or recycling. In addition, many of these properties have been operated by third parties whose treatment and disposal or release of petroleum products or wastes was not under our control. Because operating and maintaining helicopters causes us to generate, handle and dispose of materials that may be classified as “hazardous substances,” “hazardous wastes,” or other types of regulated materials, we may incur joint and several, strict liability under applicable federal laws, including the federal Comprehensive Environmental Response, Compensation, and Liability Act, also referred to as the Superfund law and the federal Resource Conservation and Recovery Act, as well as analogous state laws. Under such laws, we could be required to remove or remediate previously disposed wastes or property contamination, restore affected properties, or undertake measures to prevent future contamination. In addition, future spills or releases of regulated substances or the discovery of currently unknown contamination could expose us to material losses, expenditures and environmental liabilities, including liabilities resulting from lawsuits brought by private litigants or neighboring property owners or operators for personal injury or property damage related to our operations or the land on which our operations are conducted. We generally cannot recover these costs from insurance.

Changes in environmental laws, regulations or enforcement policies occur frequently, and any changes that result in more stringent or costly pollution control equipment, waste handling, storage, transport, disposal or cleanup requirements or other unforeseen liabilities could require us to make significant expenditures to attain and maintain compliance and may have a material adverse effect on our results of operations, competitive position or financial condition. For example, the U.S. Congress has considered, and almost one-half of the states have pursued regulatory initiatives designed to restrict the emission of carbon dioxide, methane and other greenhouse gases that may contribute to warming of the Earth’s atmosphere and other climatic changes, primarily through the planned development of greenhouse gas emission inventories and/or regional greenhouse cap and trade programs. Any adoption of laws or regulations that limits emissions of greenhouse gases from equipment or operations could result in increased costs to reduce such emissions from our operations as well as those of our customers, and could adversely affect demand for our services.

New and proposed health care legislation and regulation could have a material impact on our business.

On March 23, 2010, the Patient Protection and Affordable Care Act became law, enacting comprehensive health care reform in the United States. Many provisions of the law that could impact our business will not become effective until 2014 or later, and require implementation through regulations that have not yet been promulgated. Accordingly, we are currently evaluating the new legislation and cannot predict with any certainty what the potential impact of the new law will be on our business. The legislation aims to expand health insurance coverage to uninsured Americans, and, among other things, expands Medicaid, requires U.S. citizens and legal residents to have health insurance coverage or pay a tax penalty, and assesses fees on employers who do not offer qualifying coverage to employees. The legislation also has provisions aimed at controlling health care costs. With respect to our Air Medical operations, we may see a decrease in reimbursement amounts from Medicaid, Medicare and commercial insurance payors, but may also see an increase in payments from individuals who were previously uninsured. Federal and state governments may propose and adopt other health care initiatives or changes to current laws and regulations, the impact of which cannot be predicted.

New and proposed health care legislation and regulation could increase the cost of providing medical benefits to employees, which could have an adverse impact on our results of operations.

Recently passed legislation, described above, and future proposed legislation and regulation, could increase the cost of providing medical insurance to our employees. The cost and other effects, which may include the cost of compliance and cost of insurance, cannot be determined with certainty. If our costs increase

17

and we are unable to pass the costs to our customers, there may be a material adverse impact on our results of operations.

Our international operations are subject to political, economic and regulatory uncertainty.

Our international operations represented approximately 1% of our total operating revenues for the year ended December 31, 2009; however, we often consider international opportunities, particularly in our Oil and Gas segment, and often in lesser developed countries, and we are currently negotiating a joint venture in Brazil. International operations, particularly in lesser developed countries, are subject to a number of risks, including:

•  political, social and economic instability;

•  terrorism, kidnapping and extortion;

•  potential seizure or nationalization of assets;

•  import-export quotas; and

•  currency fluctuations or devaluation.

Additionally, our competitiveness in international markets may be adversely affected by government regulation, including regulations requiring:

•  the awarding of contracts to local contractors;

•  the employment of local citizens; and

•  the establishment of foreign subsidiaries with significant ownership positions reserved by the foreign government for local ownership.

Our failure to attract and retain qualified personnel could adversely affect us.

Our ability to attract and retain qualified pilots, mechanics, nurses, paramedics and other highly trained personnel will be an important factor in determining our future success. Many of our customers require pilots of aircraft that service them to have inordinately high levels of flight experience. The market for these experienced and highly trained personnel is extremely competitive. Accordingly, we cannot assure that we will be successful in our efforts to attract and retain such persons. Some of our pilots and mechanics, and those of our competitors, are members of the U.S. military reserves and could be called to active duty. If significant numbers of such persons are called to active duty, it would reduce the supply of such workers, possibly curtailing our operations and likely increasing our labor costs.

RISKS SPECIFIC TO OUR COMPANY

The Macondo incident could have a material adverse effect on our business.

Our business is highly dependent on the offshore oil and gas industry, with approximately 65% of our total 2009 operating revenue attributable to helicopter support for offshore oil and gas exploration and production companies, substantially all of which was in the Gulf of Mexico. Of this revenue, approximately 65% was attributable to deepwater operations. Many of the helicopters we have purchased recently are larger aircraft intended to service deepwater activities, and the margins we earn on these aircraft are generally higher than on smaller aircraft. In addition, we derive a significant amount of our revenue from a small number of major and independent oil and gas companies.

In April 2010, the Deepwater Horizon rig, engaged in deepwater drilling operations at BP’s Macondo well in the Gulf of Mexico, sank after a blowout, resulting in the discharge of substantial amounts of oil until mid-July 2010, when the flow of oil was stopped. On May 28, 2010, the Department of Interior imposed a six-month moratorium on offshore deepwater drilling operations, the enforcement of which was preliminarily enjoined, and on July 12, 2010, the Department of Interior imposed another similar moratorium set to expire November 30, 2010. As a result, deepwater drilling operations in the Gulf of Mexico were suspended. On

18

October 12, 2010, the Department of Interior lifted the moratorium on deepwater drilling. In addition, as a result of regulatory actions by the Department of Interior, there has been a “de facto” moratorium on drilling in the shallow waters of the Gulf of Mexico. It is not possible to estimate whether or when drilling operations in the Gulf of Mexico will return to normal activity levels, due to uncertainties surrounding the timing of issuance of drilling permits by the Department of Interior and new regulations related to drilling operations. BP has incurred significant costs related to the cleanup and damages caused by the oil spill and stopping the flow of oil from the well. BP is one of our major customers and accounted for approximately 14% of our total revenues in 2009.

As a result of these events, we have experienced increased flight activity, although we expect that this increased activity will decline when flight activity associated with the clean-up winds down. We estimate that the flight hours related to this increased activity were approximately 2,800 hours and 1800 hours, or 7% and 5% of total flight hours (9% and 6% of Oil and Gas segment flight hours) for the second and third quarters of 2010, respectively. Offsetting these increased flight hours are decreased flight hours resulting from the suspension of deepwater drilling activities in the Gulf of Mexico. We estimate that the adverse affect to our flight hours related to deepwater drilling rigs that have already demobilized are approximately 500 to 600 flight hours per month, or approximately 5% of Oil and Gas segment flight hours per month. Many of the deepwater drilling rigs we have been servicing are still on location (although not drilling), and therefore we are still conducting crew changes to those rigs. It is not possible to estimate how long these rigs will remain in their current status, but if these drilling rigs are demobilized or leave the Gulf of Mexico, there will be a further adverse affect to our flight activity. The majority of our transportation activity services production facilities, which were not directly impacted by the moratorium. This adds stability to our business as these are more permanent in nature.

We believe the Macondo incident is likely to result in increased costs for our exploration and production company customers operating in the Gulf of Mexico. Increased costs may cause customers to decrease their activity in the Gulf of Mexico, may decrease demand for our services, and may increase pricing pressure for our services. We cannot predict whether or to what extent drilling activities will resume in the Gulf of Mexico. Further, the potential for, or the ultimate enactment of, laws and regulations that increase the costs of, or impose additional restrictions on, drilling or operating in the Gulf of Mexico, may cause customers and potential customers to substantially limit activities in or even exit the Gulf of Mexico. Accordingly, the Macondo incident could have a material adverse effect on our business.

We are highly dependent on the offshore oil and gas industry, particularly in the Gulf of Mexico.

Approximately 65% of our 2009 operating revenue was attributable to helicopter support for offshore oil and gas exploration and production companies, substantially of which was in the Gulf of Mexico. Our business is highly dependent on the level of activity by oil and gas companies, particularly in the Gulf of Mexico. The level of activity by our customers operating in the Gulf of Mexico depends on factors that we cannot control, such as:

•  the extent to which increased government regulation or other factors may impose increased costs, including as a result of the Macondo incident, as discussed above;

•  the supply of, and demand for, oil and natural gas and market expectations regarding supply and demand;

•  weather-related or other natural causes;

•  actions of OPEC, and Middle Eastern and other oil producing countries, to control prices or change production levels;

•  general economic conditions in the United States and worldwide;

•  war, civil unrest or terrorist activities; and

•  the price and availability of alternative fuels.

19

Any substantial or extended decline in the prices of oil and natural gas could depress the level of helicopter activity in support of exploration and production activity, and thus have a material adverse effect on our business, results of operations and financial condition.

Additionally, the Gulf of Mexico is generally considered to be a mature area for oil and gas exploration, which may result in a continuing decrease in activity over time. This could materially adversely affect our business, results of operations and financial condition. In addition, the concentrated nature of our operations subjects us to the risk that a regional event could cause a significant interruption in our operations or otherwise have a material affect on our profitability.

Moreover, companies in the oil and gas exploration and production industry continually seek to implement cost-savings measures. As part of these measures, oil and gas companies have attempted to improve operating efficiencies with respect to helicopter support services. For example, certain oil and gas companies have pooled helicopter services among operators, reduced staffing levels by using technology to permit unmanned production installations and decreased the frequency of transportation of employees offshore by increasing the lengths of shifts offshore. The continued implementation of such measures could reduce demand for helicopter services and have a material adverse effect on our business, results of operations and our financial condition.

We depend on a small number of large oil and gas industry customers for a significant portion of our revenues, and our credit exposure within this industry is significant.

We derive a significant amount of our revenue from a small number of major and independent oil and gas companies. For the year ended December 31, 2009, approximately 28% of our operating revenues were attributable to our two largest customers, Shell and BP, accounting for 15% and 14%, respectively. The loss of one of our significant customers, if not offset by revenues from new or other existing customers, would have a material adverse effect on our business and operations. In addition, this concentration of customers may impact our overall credit risk in that these entities may be similarly affected by changes in economic and other conditions.

Our pilot workforce is represented by the OPEIU although the Company and the Union do not have a current agreed upon collective bargaining agreement and the Company, the Union and individual pilots are engaged in litigation.

The Company is involved in Federal Court litigation in the Western District of Louisiana and the Fifth Circuit Court of Appeals with the OPEIU, the union which represents the Company’s domestic pilots. This litigation involves claims of bad faith bargaining, compensation of striking pilots both at the time of the strike and upon their return to work under both the Railway Labor Act (“RLA”) and Louisiana state law, and the terms of employment for the Company’s pilots since the strike ended including non-payment of retention bonuses. After approximately two years of bargaining between the Company and OPEIU for a second collective bargaining agreement, including negotiations mediated by the National Mediation Board, both parties entered a self-help period as defined by the applicable labor law, the RLA. At that time the pilots commenced a strike in September 2006 and immediately prior to that strike the Company implemented its own terms and conditions of employment for the pilots. The strike ended in November 2006 and a court-approved return to work process began in January 2007 for those pilots who had not already returned to work or left the Company’s employment. This process was essentially completed in April 2007. The Company’s pilots continue to work under the terms and conditions of employment determined by the Company since the strike began. By Order dated July 9, 2010, the Court dismissed both the Company’s and OPEIU’s claims that the other had violated the RLA by bargaining in bad faith before exercising self-help. By Order dated July 30, 2010, the Court dismissed all claims that the Company violated the RLA in the manner in which it returned pilots to work following the strike. Also, the Court dismissed all but claims by 47 pilots under Louisiana state law. On August 27, 2010, the OPEIU and the individual pilot plaintiffs filed a notice of appeal with the Fifth Circuit Court of Appeals. The parties may yet proceed to trial on the claims of 47 pilots under Louisiana law that the Company improperly deducted certain sums from their final pre-strike paychecks. Such trial is scheduled for November 29, 2010. On December 31, 2009, the OPEIU filed another case against the Company

20

in the Western District of Louisiana in which the OPEIU asserts that its acceptance in 2009 of the terms and conditions of employment for the Company’s pilots initially implemented by the Company prior to the strike has created a binding collective bargaining agreement and that the Company has inappropriately made unilateral revisions to those terms including failing to pay a retention bonus. That case has been stayed by the Court pending resolution of the other litigation between the parties.

Although credit markets have improved following the credit crisis in late 2008 and 2009, there remains a risk that these markets may have an adverse impact on our business and financial condition in ways that we currently cannot predict.

The credit markets and related turmoil in the global financial system may have an adverse impact on our business and our financial condition. We cannot predict our ability to obtain lease financing due to credit availability, and this could limit our ability to fund our future growth and operations. While we have been able to obtain proposals and lease financing, we cannot predict future availability nor the effects on pricing for lease financing.

General economic conditions and recent market events may expose us to new risks.

Recent events in the financial markets have contributed to severe volatility in the securities markets, a severe liquidity crisis in the global credit markets, and unprecedented government intervention. In such an environment, significant additional risks may exist for us. The recent instability in the financial markets has led the U.S. government to take a number of unprecedented actions designed to support certain financial and other institutions and segments of the financial market that have experienced extreme volatility, and in some cases, a lack of liquidity. There can be no assurance that this intervention will improve market conditions, that such conditions will not continue to deteriorate, or that further government intervention will or will not occur.

Our Chairman of the Board and Chief Executive Officer is also our principal stockholder and has voting control of the Company.

Al A. Gonsoulin, our Chairman of the Board and Chief Executive Officer, beneficially owns stock representing approximately 52% of our total voting power. As a result, he exercises control over the election of all of our directors and the outcome of all matters requiring a stockholder vote. This ownership also may delay or prevent a change in our management or a change in control of us, even if such changes would benefit our other stockholders and were supported by a majority of our stockholders. Given his large equity ownership, his interest may not align with those of holders of the notes.

Provisions in our articles of incorporation and by-laws and Louisiana law make it more difficult to effect a change in control of us, which could discourage a takeover of our company and adversely affect the price of our common stock.

Although an attempted takeover of our company is unlikely by virtue of the ownership by our Chief Executive Officer of more than 50% of the total voting power of our capital stock, there are also provisions in our articles of incorporation and by-laws that may make it more difficult for a third party to acquire control of us, even if a change in control would result in the purchase of our company’s securities at a premium to the market price or would otherwise be beneficial to you. For example, our articles of incorporation authorize our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, it could be more difficult for a third party to acquire us.

In addition, provisions of our by-laws, such as giving the board the exclusive right to fill all board vacancies, could make it more difficult for a third party to acquire control of us. In addition to the provisions contained in our articles of incorporation and by-laws, the Louisiana Business Corporation Law (“LBCL”), includes certain provisions applicable to Louisiana corporations, such as us, which may be deemed to have an anti-takeover effect. Such provisions give stockholders the right to receive the fair value of their shares of stock following a control transaction from a controlling person or group and set forth requirements relating to

21

certain business combinations. Our descriptions of these provisions are only abbreviated summaries of detailed and complex statutes. For a complete understanding of the statutes, you should read them in their entirety.

The LBCL’s control share acquisition statute provides that any person who acquires “control shares” will be able to vote such shares only if the right to vote is approved by the affirmative vote of at least a majority of both (i) all the votes entitled to be cast by stockholders and (ii) all the votes entitled to be cast by stockholders excluding “interested shares.” The control share acquisition statute permits the articles of incorporation or by-laws of a company to exclude from the statute’s application acquisitions occurring after the adoption of the exclusion. Our by-laws do contain such an exclusion; however, our board of directors or stockholders, by an amendment to our by-laws, could reverse this exclusion.

Use of proceeds

The notes to be offered and sold using this prospectus will be offered and sold by the selling noteholders named in this prospectus. We will not receive any proceeds from the sale of such notes.

Selling noteholders

On September 23, 2010, we issued and sold, in private placements, $300,000,000 aggregate principal amount of 8.625% Senior Notes due 2018, $297,000,000 of which was sold to UBS Securities LLC, as the initial purchaser, in connection with transactions pursuant to Rule 144A and Regulation S of the Securities Act of 1933 (the “144A Notes”) and $3,000,000 of which was sold to two accredited investors pursuant to Regulation D of the Securities Act of 1933 (the “Regulation D Notes” and together with the 144A Notes, the “notes”).

Description of notes

The notes (the “Notes”) were issued by the Company under an Indenture(the “Indenture”), among itself, the Guarantors and Bank of New York Mellon Trust Company, N.A. as trustee (the “Trustee”), in private transactions that are not subject to the registration requirements of the Securities Act. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following description is a summary of the material provisions of the Indenture. It does not restate that agreement in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the Notes.

You can find the definitions of certain terms used in this description below under the heading “— Certain Definitions.” Certain defined terms used in this description but not defined below under the heading “— Certain Definitions” have the meanings assigned to them in the Indenture. In this description, the word “Issuer” or “Company” refers only to PHI, Inc. and not to any of its subsidiaries.

PRINCIPAL, MATURITY AND INTEREST

The Notes will mature on October 15, 2018. The Notes bear interest at the rate shown on the cover page of this prospectus, payable on April 15 and October 15 of each year, commencing on April 15, 2011, to Holders of record at the close of business on April 1 or October 1, as the case may be, immediately preceding the relevant interest payment date. Interest on the Notes is computed on the basis of a 360-day year of twelve 30-day months.

The Notes are issued in registered form, without coupons, and in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

An aggregate principal amount of $300 million of the Notes have been issued under the Indenture and an aggregate principal amount of up to $3 million is being registered under this prospectus. The Issuer may issue additional Notes in an unlimited aggregate principal amount having identical terms and conditions to the Notes issued (the “Additional Notes”), subject to compliance with the covenant described under “— Certain covenants — Limitations on additional indebtedness.” Any Additional Notes will be part of the same issue as the Notes already issued and will vote on all matters as one class with the Notes being issued in this offering. For purposes of this “Description of notes,” except for the covenant described under “— Certain Covenants — Limitations on additional indebtedness,” references to the Notes include Additional Notes, if any.

METHODS OF RECEIVING PAYMENTS ON THE NOTES

If a Holder has given wire transfer instructions to the Issuer at least ten Business Days prior to the applicable payment date, the Issuer will make all payments on such Holder’s Notes by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the paying agent (the “Paying Agent”) and registrar (the “Registrar”) for the Notes within the City and State of New York unless the Issuer elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders.

RANKING

The Notes are general unsecured obligations of the Issuer. The Notes rank senior in right of payment to all future obligations of the Issuer that are, by their terms, expressly subordinated in right of payment to the Notes and pari passu in right of payment with all existing and future obligations of the Issuer that are not so

23

subordinated. Each Note Guarantee (as defined below) is a general, unsecured obligation of the Guarantor thereof and ranks senior in right of payment to all future obligations of such Guarantor that are, by their terms, expressly subordinated in right of payment to such Note Guarantee and pari passu in right of payment with all existing and future obligations of such Guarantor that are not so subordinated.

The Notes and each Note Guarantee are effectively subordinated to secured Indebtedness of the Issuer and the applicable Guarantor to the extent of the value of the assets securing such Indebtedness. The Credit Agreement is secured by all of the accounts receivable and inventory (and related assets) of the Issuer and the Guarantors.

The Notes are also effectively subordinated to all existing and future obligations, including Indebtedness, of any Subsidiaries that are not Guarantors. Claims of creditors of these Subsidiaries, including trade creditors, will generally have priority as to the assets of these Subsidiaries over the claims of the Issuer and the holders of the Issuer’s Indebtedness, including the Notes.

As of September 30, 2010, the Issuer had $51.2 million of undrawn borrowings available under the Credit Agreement. Although the Indenture contains limitations on the amount of additional secured Indebtedness that the Issuer and the Restricted Subsidiaries may incur, under certain circumstances, the amount of this Indebtedness could be substantial. See “— Certain covenants — Limitations on additional indebtedness” and “— Limitations on liens.”

NOTE GUARANTEES

The Issuer’s obligations under the Notes and the Indenture are jointly and severally guaranteed (the “Note Guarantees”) by all of our Subsidiaries (other than certain Foreign Subsidiaries) and will also be guaranteed by our future Restricted Subsidiaries (other than Foreign Subsidiaries).

Not all of our Subsidiaries guarantee the Notes. Unrestricted Subsidiaries and Foreign Subsidiaries are not Guarantors. We currently have no Unrestricted Subsidiaries. Our Foreign Subsidiaries generated no or de minimis revenues and operating cash flow during the twelve-month period ended December 31, 2009 and nine months ended September 30, 2010, and had de minimis assets and liabilities and no Indebtedness (other than Indebtedness to Issuer and Restricted Subsidiaries) and no Preferred Stock outstanding as of September 30, 2010. In the event of a bankruptcy, liquidation or reorganization of any current or future non-guarantor Subsidiaries, these non-guarantor Subsidiaries will pay the holders of their debts and their trade creditors before they will be able to distribute any of their assets to us. See “— Risk factors — Risks relating to the notes — Not all of our subsidiaries guarantee the notes.”

As of the date of the Indenture, all of our Subsidiaries were “Restricted Subsidiaries.” Under the circumstances described below under the subheading “— Certain covenants — Limitations on designation of unrestricted subsidiaries,” in the future the Issuer will be permitted to designate some of its Subsidiaries as “Unrestricted Subsidiaries.” The effect of designating a Subsidiary as an “Unrestricted Subsidiary” will be:

•  an Unrestricted Subsidiary will not be subject to many of the restrictive covenants in the Indenture;

•  a Subsidiary that has previously been a Guarantor and that is designated an Unrestricted Subsidiary will be released from its Note Guarantee; and

•  the assets, income, cash flow and other financial results of an Unrestricted Subsidiary will not be consolidated with those of the Issuer for purposes of calculating compliance with the restrictive covenants contained in the Indenture.

The obligations of each Guarantor under its Note Guarantee are limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor (including, without limitation, any guarantees of Indebtedness of the Issuer under the Credit Agreement permitted under clause (1) of “— Certain covenants — Limitations on additional indebtedness”) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or

24

fraudulent transfer under applicable federal, state or foreign law. Each Guarantor that makes a payment for distribution under its Note Guarantee is entitled to a contribution from each other Guarantor in a pro rata amount based on adjusted net assets of each Guarantor.

In the event of a sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Equity Interests of any Guarantor then held by the Issuer and the Restricted Subsidiaries, except in any case to the Issuer or any Restricted Subsidiary, then that Guarantor will be released and relieved of any obligations under its Note Guarantee provided that such sale or other disposition complies with the applicable provisions of the Indenture, to the extent required thereby. See “— Certain covenants — Limitations on asset sales” and “— Limitation on mergers, consolidations, etc.” In addition, any Guarantor that is designated as an Unrestricted Subsidiary or that otherwise ceases to be a Guarantor, in each case in accordance with the provisions of the Indenture, will be released from its Note Guarantee upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary, as the case may be.

OPTIONAL REDEMPTION

Except as set forth below, the Notes may not be redeemed prior to October 15, 2014. At any time on or after October 15, 2014, the Issuer, at its option, may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning October 15 of the years indicated:

	Optional
Year	Redemption Price
2014		104.313	%
2015		102.156	%
2016		100.000	%

Notwithstanding the preceding paragraph, the Notes are redeemable by the Issuer, at its option, at any time prior to October 15, 2014, in whole or from time to time in part, at a price equal to the greater of:

•  100% of the principal amount of the Notes to be redeemed plus accrued but unpaid interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); and

•  (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the date of redemption to October 15, 2014 (except for currently accrued but unpaid interest, if any, to the date of redemption) (assuming the Notes are redeemed, and based on the applicable redemption price, on that date) discounted to the date of redemption, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate, plus 50 basis points, plus (b) accrued but unpaid interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The actual redemption price, calculated as provided in this description, will be calculated and certified to the Trustee and the Issuer by the Independent Investment Banker. For purposes of determining the optional redemption price pursuant to this paragraph, the following definitions are applicable:

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to October 15, 2014 that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity.

“Comparable Treasury Price” means, for any redemption date, (1) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such

25

Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means UBS Securities LLC and any successor firm, or if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Issuer.

“Reference Treasury Dealer” means UBS Securities LLC and its successors, plus three other dealers selected by the Independent Investment Banker that are primary U.S. government securities dealers in New York City; provided, if any of UBS Securities LLC or any primary U.S. government securities dealer selected by the Independent Investment Banker shall cease to be a primary U.S. government securities dealer, then such other primary U.S. government securities dealers as may be substituted by the Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) at 3:30 p.m., New York City time, on the third business day preceding such redemption date, as quoted in writing to the Trustee by such Reference Treasury Dealer.

“Treasury Rate” means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes to October 15, 2014, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week in which the calculation date falls (or in the immediately preceding week if the calculation date falls on any day prior to the usual publication date for such release) or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate shall be calculated on the third Business Day preceding the redemption date. Any weekly average yields calculated by interpolation or extrapolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward.

Redemption with proceeds from equity offerings

At any time prior to October 15, 2013, the Issuer may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 108.625% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that (1) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and (2) the redemption occurs within 90 days of the date of the closing of any such Qualified Equity Offering.

SELECTION AND NOTICE OF REDEMPTION

In the event that less than all of the Notes are to be redeemed at any time pursuant to an optional redemption, selection of the Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not then listed on a national security exchange, on a pro rata basis, by lot or by such method as the Trustee

26

shall deem fair and appropriate; provided, however, that no Notes of a principal amount of $2,000 or less shall be redeemed in part. In addition, if partial redemption is made pursuant to the provisions described under “— Redemption with proceeds from equity offerings,” selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of The Depository Trust Company), unless that method is otherwise prohibited.

Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the date of redemption to each Holder of Notes to be redeemed at its registered address except that a redemption notice may be given more than 60 days prior to a redemption date in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon cancellation of the original Note. On and after the date of redemption, interest will cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent for the Notes funds in satisfaction of the redemption price (including accrued and unpaid interest on the Notes to be redeemed) pursuant to the Indenture.

CHANGE OF CONTROL

Upon the occurrence of any Change of Control, each Holder will have the right to require that the Issuer purchase any or all of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase.

Within 30 days following any Change of Control, the Issuer will mail, or caused to be mailed, to the Holders a notice:

•  describing the transaction or transactions that constitute the Change of Control;

•  offering to purchase, pursuant to the procedures required by the Indenture and described in the notice (a “Change of Control Offer”), on a date specified in the notice (which shall be a Business Day not earlier than 30 days nor later than 60 days from the date the notice is mailed) and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer; and

•  describing the procedures that Holders must follow to accept the Change of Control Offer.

The Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by law.

The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the date of purchase.

If a Change of Control Offer is made, there can be no assurance that the Issuer will have available funds sufficient to pay for all or any of the Notes that might be delivered by Holders seeking to accept the Change of Control Offer. The Credit Agreement contains, and future Indebtedness that we may incur may also contain, prohibitions on the occurrence of certain events that would constitute a Change of Control or require the repurchase of such Indebtedness upon a Change of Control. Moreover, the exercise by the Holders of their right to require us to repurchase the Notes could cause a default under such Indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on us. In addition, we cannot assure you that in the event of a Change of Control the Issuer will be able to obtain the consents necessary to consummate a Change of Control Offer from the lenders under agreements governing outstanding Indebtedness which may prohibit the offer. Finally, our ability to pay cash to the holders of Notes following the occurrence of a Change of Control may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

27

The provisions described above that require us to make a Change of Control Offer following a Change of Control will be applicable regardless of whether any other provisions of the Indenture are applicable.

The Issuer’s obligation to make a Change of Control Offer will be satisfied if a third party makes the Change of Control Offer in the manner and at the times and otherwise in compliance in all material respects with the requirements applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer.

With respect to any disposition of assets, the phrase “all or substantially all” as used in the Indenture (including as set forth under “— Certain covenants — Limitations on mergers, consolidations, etc.” below) varies according to the facts and circumstances of the subject transaction, has no clearly established meaning under New York law (which governs the Indenture) and is subject to judicial interpretation. Accordingly, in certain circumstances there may be a degree of uncertainty in ascertaining whether a particular transaction would involve a disposition of “all or substantially all” of the assets of the Issuer, and therefore it may be unclear as to whether a Change of Control has occurred and whether the Holders have the right to require the Issuer to purchase Notes.

The Issuer will comply with applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Change of Control” provisions of the Indenture, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the “Change of Control” provisions of the Indenture by virtue of this compliance.

CERTAIN COVENANTS

The Indenture contains, among others, the covenants summarized below. Following the first day (the “Suspension Date”) that:

(1) the Notes have an Investment Grade Rating from both of the Rating Agencies, and

(2) no Default has occurred and is continuing under the Indenture, the Issuer and its Restricted Subsidiaries will not be subject to the provisions of the Indenture summarized below under:

(1) “— Limitations on additional indebtedness,”

(2) “— Limitations on layering indebtedness,”

(3) “— Limitations on restricted payments,”

(4) “— Limitations on dividend and other restrictions affecting restricted subsidiaries,”

(5) “— Limitations on transactions with affiliates,”

(6) “— Limitations on asset sales,”

(7) subclause (a) of clause (1) and clause (3) of “— Limitations on sale and leaseback transactions,”

(8) “— Limitations on the issuance or sale of equity interests of restricted subsidiaries,”

(9) clause (3) of the first paragraph under “— Limitations on mergers, consolidations, etc.” and

(10) “— Conduct of business.”

(collectively, the “Suspended Covenants”). If the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding, and on any subsequent date (the “Reversion Date”) one of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Notes below an Investment Grade Rating, then the Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants with respect to future events. The period of time between the Suspension Date and the Reversion Date is referred to in this description as the “Suspension

28

Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspension Period.

On the Reversion Date, all Indebtedness incurred during the Suspension Period will be classified to have been incurred pursuant to the first paragraph of “— Limitations on additional indebtedness” or one of the clauses set forth in the second paragraph of “— Limitations on additional indebtedness” (to the extent such Indebtedness would be permitted to be incurred thereunder as of the Reversion Date and after giving effect to Indebtedness incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be incurred pursuant to either paragraph of “— Limitations on additional indebtedness,” such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (3) of the second paragraph of “— Limitations on additional indebtedness.” Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under “— Limitations on restricted payments” will be made as though the covenant described under “— Limitations on restricted payments” had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount of the Restricted Payments Basket. For purposes of determining compliance with the “— Limitations on asset sales” covenant, on the Reversion Date the Net Available Proceeds from all Asset Sales not applied or invested in accordance with the covenant will be deemed to be reset to zero.

Limitations on additional indebtedness

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness; provided that the Issuer or any Guarantor may incur additional Indebtedness if, after giving effect thereto, the Consolidated Interest Coverage Ratio, determined on a pro forma basis giving effect to such incurrence and the application of the proceeds thereof, would be at least 2.25 to 1.00 (the “Coverage Ratio Exception”).

Notwithstanding the above, each of the following shall be permitted (the “Permitted Indebtedness”):

(1) Indebtedness of the Issuer and any Guarantor under Credit Facilities (including reimbursement obligations with regard to letters of credit) incurred pursuant to this clause (1) in an aggregate amount at any time outstanding not to exceed the greater of (x) $85.0 million and (y) 80% of the book value of the accounts receivable plus 50% of the book value of inventory of the Issuer and the Restricted Subsidiaries, calculated on a consolidated basis and in accordance with GAAP (giving pro forma effect to acquisitions made in connection with the borrowing of any such Indebtedness);

(2) the Notes issued on the Issue Date and the Note Guarantees;

(3) Indebtedness of the Issuer and the Restricted Subsidiaries to the extent outstanding on the Issue Date (other than Indebtedness referred to in clauses (1) and (2) above, and after giving effect to the intended use of proceeds of the Notes);

(4) Indebtedness under Hedging Obligations; provided that such Hedging Obligations are incurred by the Issuer or any Restricted Subsidiary in the ordinary course of business and not for the purpose of speculation;

(5) Indebtedness of the Issuer owed to a Restricted Subsidiary and Indebtedness of any Restricted Subsidiary owed to the Issuer or any other Restricted Subsidiary; provided, however, that upon any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or such Indebtedness being owed to any Person other than the Issuer or a Restricted Subsidiary, the Issuer or such Restricted Subsidiary, as applicable, shall be deemed to have incurred Indebtedness not permitted by this clause (5);

(6) Indebtedness in respect of bid, performance or surety bonds issued for the account of the Issuer or any Restricted Subsidiary in the ordinary course of business, including guarantees or obligations of the Issuer or any Restricted Subsidiary with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for an obligation for money borrowed);

29

(7) Purchase Money Indebtedness incurred by the Issuer or any Restricted Subsidiary, and Refinancing Indebtedness thereof, in an aggregate amount not to exceed at any time outstanding the greater of (a) $50.0 million and (b) 20% of the net book value of the aircraft owned by the Issuer and the Restricted Subsidiaries;

(8) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is extinguished within five Business Days of incurrence;

(9) Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(10) Refinancing Indebtedness with respect to Indebtedness incurred pursuant to the Coverage Ratio Exception or clause (2) or (3) above or this clause (10);

(11) (a) Indebtedness of any Foreign Subsidiary (or guarantees thereof by the Issuer or any Guarantor in respect thereof) (“Foreign Indebtedness”) and (b) guarantees of Indebtedness of a partnership or joint venture (other than an Unrestricted Subsidiary) by the Issuer or any Guarantor provided that such guarantee does not exceed the proportion of such Indebtedness that is equal to the Issuer’s or Guarantor’s proportionate equity ownership of such partnership or joint venture, and provided that the aggregate principal amount of Indebtedness at any time outstanding incurred pursuant to the foregoing clauses (a) and (b) does not exceed $15.0 million; and

(12) Indebtedness of the Issuer or any Restricted Subsidiary in an aggregate amount not to exceed $30.0 million at any time outstanding.

For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (12) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify or later reclassify such item of Indebtedness and may divide and classify or later reclassify such Indebtedness in more than one of the types of Indebtedness described, except that Indebtedness incurred under the Credit Agreement and outstanding on the Issue Date shall be deemed to have been incurred under clause (1) above.

Limitations on layering indebtedness

The Issuer will not, and will not permit any Guarantor to, directly or indirectly, incur any Indebtedness that is or purports to be by its terms (or by the terms of any agreement governing such Indebtedness) subordinated to any other Indebtedness of the Issuer or of such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the Note Guarantee of such Guarantor, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Issuer or such Guarantor, as the case may be.

Limitations on restricted payments

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, make any Restricted Payment if at the time of such Restricted Payment:

(1) a Default shall have occurred and be continuing or shall occur as a consequence thereof;

(2) the Issuer cannot incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

(3) the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after the Issue Date (other than Restricted Payments made pursuant to clause

30

(2), (3), (4), (5), (6), (7) or (8) of the next paragraph), exceeds the sum (the “Restricted Payments Basket”) of (without duplication):

(a) 50% of Consolidated Net Income for the period (taken as one accounting period) commencing on July 1, 2002 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100% of such aggregate deficit), plus

(b) 100% of the aggregate net cash proceeds received by the Issuer either (x) as contributions to the common equity of the Issuer after the Issue Date or (y) from the issuance and sale of Qualified Equity Interests after the Issue Date, other than any such proceeds which are used to redeem Notes in accordance with “— Optional redemption — Redemption with proceeds from equity offerings,” plus

(c) the aggregate amount by which Indebtedness incurred by the Issuer or any Restricted Subsidiary subsequent to the Issue Date is reduced on the Issuer’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Issuer) into Qualified Equity Interests (less the amount of any cash, or the Fair Market Value of assets, distributed by the Issuer or any Restricted Subsidiary upon such conversion or exchange), plus

(d) in the case of the disposition or repayment of or return on any Investment that was treated as a Restricted Payment made after the Issue Date, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) the return of capital with respect to such Investment and (ii) the amount of such Investment that was treated as a Restricted Payment, in either case, less the cost of the disposition of such Investment and net of taxes, plus

(e) upon a Redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the lesser of (i) the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary immediately following such Redesignation, and (ii) the aggregate amount of the Issuer’s Investments in such Subsidiary to the extent such Investments reduced the Restricted Payments Basket and were not previously repaid or otherwise reduced.

The foregoing provisions will not prohibit:

(1) the payment by the Issuer or any Restricted Subsidiary of any dividend within 60 days after the date of declaration thereof, if on the date of declaration the payment would have complied with the provisions of the Indenture;

(2) the redemption of any Equity Interests of the Issuer or any Restricted Subsidiary in exchange for, or out of the proceeds of the substantially concurrent issuance and sale of, Qualified Equity Interests;

(3) the redemption of Subordinated Indebtedness of the Issuer or any Restricted Subsidiary (a) in exchange for, or out of the proceeds of the substantially concurrent issuance and sale of, Qualified Equity Interests or (b) in exchange for, or out of the proceeds of the substantially concurrent incurrence of, Refinancing Indebtedness permitted to be incurred under the “Limitations on additional indebtedness” covenant and the other terms of the Indenture;

(4) the redemption of any Equity Interests of the Issuer or any Restricted Subsidiary of the Issuer held by any of the Issuer’s (or any of its Restricted Subsidiaries’) current or former directors or employees (or their transferees, estates or beneficiaries under their estates) pursuant to any director or employee equity subscription agreement or stock option agreement; provided that the aggregate price paid for all such redeemed Equity Interests may not exceed $2.5 million in any twelve-month period (with unused amounts in any 12-month period being permitted to be carried over into the next 12-month period); provided, further, that the amounts in any 12-month period may be increased by an amount not to exceed (A) the cash proceeds received by the Issuer or any of its Restricted Subsidiaries from the sale of Issuer’s Equity Interests (other than Disqualified Equity Interests) to any such directors or employees that occurs after the Issue Date to the extent such proceeds have not otherwise been applied to the

31

payment of Restricted Payments plus (B) the cash proceeds of key man life insurance policies received by the Issuer and its Restricted Subsidiaries after the Issue Date;

(5) the redemption of Equity Interests of the Issuer or any Restricted Subsidiary of the Issuer held by any of the Issuer’s (or any of its Restricted Subsidiaries’) current or former directors or employees in connection with the exercise or vesting of any equity compensation (including, without limitation, stock options, restricted stock and phantom stock) in order to satisfy the Issuer’s or such Restricted Subsidiary’s tax withholding obligation with respect to such exercise or vesting;

(6) repurchases of Equity Interests deemed to occur upon the exercise of stock options if the Equity Interests represent a portion of the exercise price thereof;

(7) in the event of a Change of Control, the redemption of Subordinated Indebtedness of the Issuer or any Guarantor, in each case, at a redemption price not greater than 101% of the principal amount (or, if such Subordinated Indebtedness were issued with original issue discount, 101% of the accreted value) of such Subordinated Indebtedness, plus any accrued and unpaid interest thereon; provided, however, that prior to such redemption, the Issuer (or a third party to the extent permitted by the Indenture) has made a Change of Control Offer with respect to the Notes as a result of such Change of Control and has purchased all Notes validly tendered and not withdrawn in connection with such Change of Control Offer; or

(8) in the event of an Asset Sale that requires the Issuer to offer to repurchase Notes pursuant to the covenant described under “— Limitations on asset sales,” redemption of Subordinated Indebtedness of the Issuer or any Guarantor, in each case, at a redemption price not greater than 100% of the principal amount (or, if such Subordinated Indebtedness were issued with original issue discount, 100% of the accreted value) of such Subordinated Indebtedness, plus any accrued and unpaid interest thereon; provided, however, that (A) prior to such redemption, the Issuer has made a Net Proceeds Offer with respect to the Notes pursuant to the provisions of the covenant described under “— Limitations on asset sales” and has purchased all Notes required to be purchased by it under such covenant;

provided that (a) in the case of any Restricted Payment pursuant to clause (3), (7) or (8) above, no Default shall have occurred and be continuing or occur as a consequence thereof and (b) no issuance and sale of Qualified Equity Interests pursuant to clause (2) or (3) above shall increase the Restricted Payments Basket.

Limitations on dividend and other restrictions affecting restricted subsidiaries

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on or in respect of its Equity Interests;

(2) make loans or advances or pay any Indebtedness or other obligation owed to the Issuer or any other Restricted Subsidiary; or

(3) transfer any of its assets to the Issuer or to any Restricted Subsidiary that owns Equity Interests in such Restricted Subsidiary (pro rata in accordance with such ownership interest); except for:

(a) encumbrances or restrictions existing under or by reason of applicable law;

(b) encumbrances or restrictions existing under the Indenture, the Notes and the Note Guarantees;

(c) non-assignment provisions of any contract, license or any lease entered into in the ordinary course of business;

(d) encumbrances or restrictions existing under agreements existing on the date of the Indenture (including, without limitation, the Credit Agreement) as in effect on that date;

32

(e) restrictions on the transfer of assets subject to any Lien permitted under the Indenture imposed by the holder of such Lien;

(f) any restriction with respect to a Restricted Subsidiary (or any of its assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the Equity Interests or assets of such Restricted Subsidiary (or the assets that are subject to such restriction) pending the closing of such sale or disposition;

(g) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the assets of any Person, other than the Person or the assets of the Person so acquired;

(h) any other agreement governing Indebtedness entered into after the Issue Date that contains encumbrances and restrictions taken as a whole that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date (including the Indenture and the Credit Agreement);

(i) customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements and other similar agreements entered into in the ordinary course of business that restrict the transfer of ownership interests in such partnership, limited liability company, joint venture or similar Person;

(j) Purchase Money Indebtedness incurred in compliance with the covenant described under “— Limitations on additional indebtedness” that impose restrictions of the nature described in clause (3) above on the assets acquired;

(k) encumbrances or restrictions applicable only to a Foreign Subsidiary;

(l) any encumbrances or restrictions imposed by any amendments or refinancings of the contracts, instruments or obligations referred to in clauses (a) through (k) above; provided that such amendments or refinancings are, in the good faith judgment of the Issuer’s Board of Directors, no more materially restrictive with respect to such encumbrances and restrictions than those prior to such amendments or refinancings; and

(m) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

Limitations on transactions with affiliates

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”), unless:

(1) such Affiliate Transaction is on terms that are no less favorable to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis by the Issuer or that Restricted Subsidiary from a Person that is not an Affiliate of the Issuer or that Restricted Subsidiary; and

(2) the Issuer delivers to the Trustee:

(a) with respect to any Affiliate Transaction involving aggregate value in excess of $5.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by the Independent Directors approving such Affiliate Transaction; and

(b) with respect to any Affiliate Transaction involving aggregate value of $20.0 million or more, the certificate described in the preceding clause (a) and a written opinion as to the fairness of

33

such Affiliate Transaction to the Issuer or such Restricted Subsidiary from a financial point of view issued by an Independent Financial Advisor.

The foregoing restrictions shall not apply to:

(1) transactions exclusively between or among (a) the Issuer and one or more Restricted Subsidiaries or (b) Restricted Subsidiaries; provided, in each case, that no Affiliate of the Issuer (other than another Restricted Subsidiary) owns Equity Interests of any such Restricted Subsidiary;

(2) reasonable director, officer and employee compensation (including bonuses) and other benefits (including retirement, health, stock option and other benefit plans) and indemnification arrangements;

(3) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes, on the other hand, which payments by the Issuer and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis;

(4) loans and advances permitted by clause (3) of the definition of “Permitted Investments;”

(5) Restricted Payments which are made in accordance with the covenant described under “— Limitations on restricted payments;”

(6) any transaction with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Issuer solely because the Issuer owns Equity Interests in such Person, provided that no other Affiliate of the Issuer (other than a Restricted Subsidiary) owns Equity Interests in such Person; or

(7) any transaction with an Affiliate where the only consideration paid by the Issuer or any Restricted Subsidiary is Qualified Equity Interests.

Limitations on liens

The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien of any nature whatsoever against (other than Permitted Liens) any assets of the Issuer or any Guarantor (including Equity Interests of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom, unless contemporaneously therewith:

(1) in the case of any Lien securing an obligation that ranks pari passu with the Notes or a Note Guarantee, effective provision is made to secure the Notes or such Note Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same collateral; and

(2) in the case of any Lien securing an obligation that is subordinated in right of payment to the Notes or a Note Guarantee, effective provision is made to secure the Notes or such Note Guarantee, as the case may be, with a Lien on the same collateral that is prior to the Lien securing such subordinated obligation,

in each case, for so long as such obligation is secured by such Lien.

Limitations on asset sales

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets included in such Asset Sale; and

(2) at least 75% of the total consideration received in such Asset Sale consists of cash or Cash Equivalents.

34

For purposes of clause (2), the following shall be deemed to be cash:

(a) the amount (without duplication) of any Indebtedness or other liabilities of the Issuer or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are satisfied or assumed by the transferee in such Asset Sale pursuant to a customary novation agreement that releases the Issuer or such Restricted Subsidiary from further liability;

(b) the amount of any obligations received from such transferee that are within 90 days converted by the Issuer or such Restricted Subsidiary to cash (to the extent of the cash actually so received); and

(c) the Fair Market Value of any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business.

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale and the Net Available Proceeds thereof shall be applied in accordance with this covenant.

If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom (or enter into a definitive agreement for such application within such 365-day period, provided that any resulting capital expenditure or purchase is closed within 90 days after the end of such 365-day period) to:

(1) repay or redeem any Indebtedness of the Company or a Restricted Subsidiary, other than Subordinated Indebtedness, Disqualified Equity Interests, intercompany Indebtedness, or Indebtedness owed to an Affiliate of the Company; or

(2) invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities) to be used by the Issuer or any Restricted Subsidiary in a Permitted Business, or Equity Interests of a Person that upon such purchase will become a Restricted Subsidiary that directly or indirectly, through one or more Subsidiaries that will become Restricted Subsidiaries, owns assets to be used in a Permitted Business.

Pending the final application of any such Net Available Proceeds, the Issuer or a Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest such Net Available Proceeds in any manner that is not prohibited by the Indenture.

The amount of Net Available Proceeds not applied or invested as provided in the second preceding paragraph will constitute “Excess Proceeds.”

When the aggregate amount of Excess Proceeds equals or exceeds $10.0 million, the Issuer shall make an offer to purchase from all Holders and, if applicable, redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer or any Guarantor the provisions of which require the Issuer or such Guarantor to redeem such Indebtedness with the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows:

(1) the Issuer will (a) make an offer to purchase (a “Net Proceeds Offer”) to all Holders in accordance with the procedures set forth in the Indenture, and (b) redeem (or make an offer to do so) any such Pari Passu Indebtedness, pro rata in proportion to the respective principal amounts of the Notes and such Pari Passu Indebtedness required to be redeemed, the maximum principal amount of Notes and such Pari Passu Indebtedness that may be redeemed out of the amount (the “Payment Amount”) of such Excess Proceeds;

(2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the

35

procedures set forth in the Indenture and the redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness;

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis; and

(4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for general corporate purposes, subject to the provisions of the Indenture.

In the event of the transfer of substantially all (but not all) of the assets of the Issuer and the Restricted Subsidiaries (taken as a whole) to a Person in a transaction covered by and effected in accordance with the covenant described under “— Limitations on mergers, consolidations, etc.,” the successor Person shall be deemed to have sold for cash at Fair Market Value the assets of the Issuer and the Restricted Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it were an Asset Sale (with such Fair Market Value being deemed to be Net Available Proceeds for such purpose).

The Issuer will comply with applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act, and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Limitations on asset sales” provisions of the Indenture, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the “Limitations on asset sales” provisions of the Indenture by virtue of this compliance.

Limitations on designation of unrestricted subsidiaries

The Issuer may designate any Subsidiary of the Issuer as an “Unrestricted Subsidiary” under the Indenture (a “Designation”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to the first paragraph of “— Limitations on restricted payments” above, in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless such Subsidiary:

(1) has no Indebtedness other than Non-Recourse Debt;

(2) is not party to any agreement, contract, arrangement or understanding with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are reasonably similar or more favorable to the Issuer or the Restricted Subsidiary as those that might be obtained at the time from Persons who are not Affiliates;

(3) is a Person with respect to which neither the Issuer nor any Restricted Subsidiary has any direct or indirect obligation (a) to subscribe for additional Equity Interests or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results; and

36

(4) has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any Restricted Subsidiary, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary, and except to the extent the amount thereof constitutes a Restricted Payment permitted pursuant to the covenant described under “— Limitations on restricted payments.”

If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of the date and, if the Indebtedness is not permitted to be incurred under the covenant described under “— Limitations on additional indebtedness” or the Lien is not permitted under the covenant described under “— Limitations on liens,” the Issuer shall be in default of the applicable covenant.

The Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of the Indenture.

All Designations and Redesignations must be evidenced by resolutions of the Board of Directors of the Issuer, delivered to the Trustee certifying compliance with the foregoing provisions.

Limitations on sale and leaseback transactions

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into any Sale and Leaseback Transaction; provided that the Issuer or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

(1) the Issuer or such Restricted Subsidiary could have (a) incurred the Attributable Indebtedness relating to such Sale and Leaseback Transaction pursuant to the covenant described under “— Limitations on additional indebtedness” and (b) incurred a Lien to secure such Indebtedness without equally and ratably securing the Notes pursuant to the covenant described under “— Limitations on liens;”

(2) the gross cash proceeds of such Sale and Leaseback Transaction are at least equal to the Fair Market Value of the asset that is the subject of such Sale and Leaseback Transaction; and

(3) transfer of assets in such Sale and Leaseback Transaction is permitted by, and the Issuer or the applicable Restricted Subsidiary applies the proceeds of such transaction in accordance with, the covenant described under “— Limitations on asset sales.”

Limitations on the issuance or sale of equity interests of restricted subsidiaries

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, sell or issue any Equity Interests of any Restricted Subsidiary except (1) to the Issuer, a Restricted Subsidiary or the minority Equity Interest holders of any Restricted Subsidiary, on a pro rata basis, at Fair Market Value, or (2) to the extent such Equity Interests represent directors’ qualifying shares or Equity Interests required by applicable law to be held by a Person other than the Issuer or a Wholly-Owned Restricted Subsidiary. The sale of all the Equity Interests of any Restricted Subsidiary is permitted by this covenant but is subject to the covenant described under “— Limitations on asset sales.”

37

Limitations on mergers, consolidations, etc.

The Issuer will not, directly or indirectly, in a single transaction or a series of related transactions, (a) consolidate or merge with or into (other than a merger with a Wholly-Owned Restricted Subsidiary solely for the purpose of changing the Issuer’s jurisdiction of incorporation to another State of the United States), or sell, lease, transfer, convey or otherwise dispose of all or substantially all of the assets of the Issuer or the Issuer and the Restricted Subsidiaries (taken as a whole) or (b) consummate a Plan of Liquidation unless, in either case:

(1) either:

(a) the Issuer will be the surviving or continuing Person; or

(b) the Person formed by or surviving such consolidation or merger or to which such sale, lease, transfer, conveyance or other disposition shall be made (or, in the case of a Plan of Liquidation, any Person to which assets are transferred) (collectively, the “Successor”) is an entity organized and existing under the laws of any State of the United States of America or the District of Columbia, and the Successor expressly assumes, by supplemental indenture in form and substance satisfactory to the Trustee, all of the obligations of the Issuer under the Notes, the Indenture and the Registration Rights Agreement;

(2) immediately prior to and immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (1)(b) above and the incurrence of any Indebtedness to be incurred in connection therewith, no Default shall have occurred and be continuing; and

(3) immediately after and giving effect to such transaction and the assumption of the obligations set forth in clause (1)(b) above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, the Issuer or the Successor, as the case may be, could incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception.

For purposes of this covenant, any Indebtedness of the Successor which was not Indebtedness of the Issuer immediately prior to the transaction shall be deemed to have been incurred in connection with such transaction.

Except in circumstances where its Guarantee may be released as provided in the last paragraph under the caption “— Note Guarantees,” no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuer or another Guarantor, unless:

(1) either:

(a) such Guarantor will be the surviving or continuing Person; or

(b) the Person formed by or surviving any such consolidation or merger assumes, by supplemental indenture in form and substance satisfactory to the Trustee, all of the obligations of such Guarantor under the Note Guarantee of such Guarantor, the Indenture and the Registration Rights Agreement; and

(2) immediately after giving effect to such transaction, no Default shall have occurred and be continuing.

For purposes of the foregoing, the disposition (by lease, assignment, sale or otherwise, in a single transaction or series of related transactions) of all or substantially all of the assets of one or more Restricted Subsidiaries, the Equity Interests of which constitute all or substantially all of the assets of the Issuer, will be deemed to be the disposition of all or substantially all of the assets of the Issuer.

Upon any consolidation or merger of the Issuer or a Guarantor, or any disposition of all or substantially all of the assets of the Issuer or the Issuer and the Restricted Subsidiaries (taken as a whole) in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor under the Notes or its Note Guarantee, the Person formed by such consolidation or into which the Issuer or such Guarantor is merged or to which the disposition is made will succeed to, and be substituted for, and may exercise every right and

38

power of, the Issuer or such Guarantor under the Indenture, the Notes and the Note Guarantees with the same effect as if such Person had been named therein as the Issuer or such Guarantor and, except in the case of a lease of all or substantially all of such assets, the Issuer will be released from the obligation to pay the principal of and interest on the Notes and all of the Issuer’s other obligations and covenants under the Notes and the Indenture. Such Guarantor will be released from its Note Guarantee on the conditions described in the last paragraph under “— Note guarantees.”

Additional Note guarantees

If, after the Issue Date, (a) the Issuer or any Restricted Subsidiary shall acquire or create another Subsidiary (other than in any case a Foreign Subsidiary or Subsidiary that has been designated an Unrestricted Subsidiary) or (b) any Unrestricted Subsidiary that is not a Foreign Subsidiary is redesignated a Restricted Subsidiary, then, in each such case, the Issuer shall cause such Restricted Subsidiary to:

(1) execute and deliver to the Trustee within 20 days (a) a supplemental indenture in the form included in the Indenture pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and the Indenture and (b) a notation of guarantee in respect of its Note Guarantee; and

(2) deliver to the Trustee one or more opinions of counsel that such supplemental indenture (a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b) constitutes a valid and legally binding obligation of such Restricted Subsidiary in accordance with its terms.

Conduct of business

The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business.

Reports

Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer will furnish (without exhibits) to the Holders of Notes, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Issuer were required to file these Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s certified independent accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file these reports.

In addition, whether or not required by the SEC, the Issuer will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept the filing) and make the information available to securities analysts and prospective investors upon request. For so long as any Notes remain outstanding, the Issuer will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

EVENTS OF DEFAULT

Each of the following is an “Event of Default:”

(1) failure by the Issuer to pay interest on any of the Notes when it becomes due and payable and the continuance of any such failure for 30 days;

39

(2) failure by the Issuer to pay the principal of or premium, if any, on any of the Notes when it becomes due and payable, whether at stated maturity, upon redemption, upon acceleration or otherwise;

(3) failure by the Issuer to comply with any of its agreements or covenants described above under “— Certain covenants — Limitations on mergers, consolidations, etc.” or in respect of its obligations to make a Change of Control Offer as described above under “— Change of control;”

(4) failure by the Issuer to comply with any other agreement or covenant in the Indenture and continuance of this failure for 60 days after notice of the failure has been given to the Issuer by the Trustee or by the Holders of at least 25% of the aggregate principal amount of the Notes then outstanding;

(5) default under any mortgage, indenture or other instrument or agreement under which there may be issued or by which there may be secured or evidenced Indebtedness of the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the Issue Date, which default:

(a) is caused by a failure to pay when due principal on such Indebtedness within the applicable express grace period,

(b) results in the acceleration of such Indebtedness prior to its express final maturity or

(c) results in the commencement of judicial proceedings to foreclose upon, or to exercise remedies under applicable law or applicable security documents to take ownership of, the assets securing such Indebtedness, and

in each case, the principal amount of such Indebtedness, together with any other Indebtedness with respect to which an event described in clause (a), (b) or (c) has occurred and is continuing, aggregates $20.0 million or more;

(6) one or more judgments or orders that exceed $20.0 million in the aggregate (net of amounts covered by insurance or bonded) for the payment of money have been entered by a court or courts of competent jurisdiction against the Issuer or any Restricted Subsidiary and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within 60 days of being entered;

(7) the Issuer or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case,

(b) consents to the entry of an order for relief against it in an involuntary case,

(c) consents to the appointment of a Custodian of it or for all or substantially all of its assets, or

(d) makes a general assignment for the benefit of its creditors;

(8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a) is for relief against the Issuer or any Significant Subsidiary as debtor in an involuntary case,

(b) appoints a Custodian of the Issuer or any Significant Subsidiary or a Custodian for all or substantially all of the assets of the Issuer or any Significant Subsidiary, or

(c) orders the liquidation of the Issuer or any Significant Subsidiary, and the order or decree remains unstayed and in effect for 60 days; or

(9) any Note Guarantee of any Significant Subsidiary ceases to be in full force and effect (other than in accordance with the terms of such Note Guarantee and the Indenture) or is declared null and void and unenforceable or found to be invalid or any Guarantor denies its liability under its Note Guarantee (other than by reason of release of a Guarantor from its Note Guarantee in accordance with the terms of the Indenture and the Note Guarantee).

40

If an Event of Default (other than an Event of Default specified in clause (7) or (8) above with respect to the Issuer), shall have occurred and be continuing under the Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare all amounts owing under the Notes to be due and payable immediately. Upon such declaration of acceleration, the aggregate principal of, premium, if any, and accrued and unpaid interest on the outstanding Notes shall immediately become due and payable; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, premium, if any, and interest, have been cured or waived as provided in the Indenture. If an Event of Default specified in clause (7) or (8) with respect to the Issuer occurs, all outstanding Notes shall become due and payable without any further action or notice.

The Trustee shall, within 30 days after the occurrence of any Default with respect to the Notes, give the Holders notice of all uncured Defaults thereunder known to it; provided, however, that, except in the case of an Event of Default in payment with respect to the Notes or a Default in complying with “— Certain covenants — Limitations on mergers, consolidations, etc.,” the Trustee shall be protected in withholding such notice if and so long as a committee of its trust officers in good faith determines that the withholding of such notice is in the interest of the Holders.

No Holder will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless the Trustee:

(1) has failed to act for a period of 60 days after receiving written notice of a continuing Event of Default by such Holder and a request to act by Holders of at least 25% in aggregate principal amount of Notes outstanding;

(2) has been offered indemnity satisfactory to it in its reasonable judgment; and

(3) has not received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request within such 60-day period. However, such limitations do not apply to a suit instituted by a Holder of any Note for enforcement of payment of the principal of or interest on such Note on or after the due date therefor (after giving effect to the grace period specified in clause (1) of the first paragraph of this “— Events of default” section).

The Issuer is required to deliver to the Trustee annually a statement regarding compliance with the Indenture and, upon any Officer of the Issuer becoming aware of any Default, a statement specifying such Default and what action the Issuer is taking or proposes to take with respect thereto.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

The Issuer may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors discharged with respect to the outstanding Notes (“Legal Defeasance”). Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and the Note Guarantees, and the Indenture shall cease to be of further effect as to all outstanding Notes and Note Guarantees, except as to

(1) rights of Holders to receive payments in respect of the principal of, premium, if any, on and interest on the Notes when such payments are due from the trust funds referred to below,

(2) the Issuer’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, replacement of mutilated, destroyed, lost or stolen Notes, and the maintenance of an office or agency for payment and money for security payments held in trust,

(3) the rights, powers, trust, duties and immunities of the Trustee, and the Issuer’s obligations in connection therewith,

(4) the Issuer’s rights of optional redemption, and

(5) the Legal Defeasance provisions of the Indenture.

41

In addition, the Issuer may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors released with respect to most of the covenants under the Indenture, except as described otherwise in the Indenture (“Covenant Defeasance”), and thereafter any omission to comply with such obligations shall not constitute a Default. In the event Covenant Defeasance occurs, certain Events of Default (not including non-payment and, solely for a period of 91 days following the deposit referred to in clause (1) of the next paragraph, bankruptcy, receivership, rehabilitation and insolvency events) will no longer apply. Covenant Defeasance will not be effective until such bankruptcy, receivership, rehabilitation and insolvency events no longer apply. The Issuer may exercise its Legal Defeasance option regardless of whether it previously exercised Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without reinvestment) in the opinion of a nationally recognized firm of independent public accountants selected by the Issuer, to pay the principal of, premium, if any, on and interest on the Notes on the stated date for payment or on the redemption date of the principal or installment of principal of or interest on the Notes, and the Holders must have a valid, perfected, exclusive security interest in such trust,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) the Issuer has received from, or there has been published by the Internal Revenue Service, a ruling, or

(b) since the date of the Indenture, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon this opinion of counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred,

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Indenture or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound,

(6) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others, and

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that the conditions provided for in, in the case of the Officers’ Certificate, clauses (1) through (6) and, in the case of the opinion of counsel, clauses (1) (with respect to the validity and perfection of the security interest), (2) and/or (3) and (5) of this paragraph have been complied with.

42

If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of, premium, if any, and interest on the Notes when due, then the Issuer’s obligations and the obligations of Guarantors under the Indenture will be revived and no such defeasance will be deemed to have occurred.

SATISFACTION AND DISCHARGE

The Indenture will be discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled) as to all outstanding Notes when either

(1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust) have been delivered to the Trustee for cancellation, or

(2) (a) all Notes not delivered to the Trustee for cancellation otherwise have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee funds in trust in an amount of money sufficient to pay and discharge the entire Indebtedness (including all principal, premium, if any, and accrued and unpaid interest) on the Notes not theretofore delivered to the Trustee for cancellation,

(b) the Issuer has paid all sums payable by it under the Indenture, and

TRANSFER AND EXCHANGE

A Holder will be able to register the transfer of Notes only in accordance with the provisions of the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Without the prior consent of the Issuer, the Registrar is not required (1) to register the transfer of or exchange any Note selected for redemption, (2) to register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or (3) to register the transfer or exchange of a Note between a record date and the next succeeding interest payment date.

The Notes will be issued in registered form and the registered Holder will be treated as the owner of such Note for all purposes.

AMENDMENT, SUPPLEMENT AND WAIVER

Subject to certain exceptions, the Indenture or the Notes may be amended with the consent (which may include consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default in the payment of the principal of, premium, if any, on or interest on the Notes) with the consent (which may include consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of a majority in aggregate principal amount of the Notes then outstanding; provided that:

(1) no such amendment may, without the consent of the Holders of two-thirds in aggregate principal amount of Notes then outstanding, amend the obligations of the Issuer under the heading “— Change of control” or the related definitions that could adversely affect the rights of any Holder; and

(2) without the consent of each Holder affected, the Issuer, the Guarantors and the Trustee may not:

(a) change the maturity of any Note;

43

(b) reduce the amount, extend the due date or otherwise affect the terms of any scheduled payment of interest on or principal of the Notes;

(c) reduce any premium payable upon optional redemption of the Notes, change the date on which any Notes are subject to redemption or otherwise alter the provisions with respect to the redemption of the Notes;

(d) make any Note payable in money or currency other than that stated in the Notes;

(e) modify or change any provision of the Indenture or the related definitions to affect the ranking of the Notes or any Note Guarantee in a manner that adversely affects the Holders;

(f) reduce the percentage of Holders necessary to consent to an amendment or waiver to the Indenture or the Notes;

(g) impair the right of any Holder of the Notes to receive payment of principal of, premium, if any, and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

(h) release any Guarantor from any of its obligations under its Note Guarantee or the Indenture, except as permitted by the Indenture; or

(i) make any change in these amendment and waiver provisions.

Notwithstanding the foregoing, the Issuer, the Guarantors and the Trustee may amend the Indenture, the Note Guarantees or the Notes without the consent of any Holder: to cure any ambiguity, defect or inconsistency; to provide for uncertificated Notes in addition to or in place of certificated Notes; to provide for the assumption of the Issuer’s or any Guarantor’s obligations to the Holders in the case of a merger or acquisition; to add Guarantors or to release any Guarantor from any of its obligations under its Note Guarantee or the Indenture (to the extent permitted by the Indenture); to make any change that does not materially adversely affect the legal rights of any Holder, provided that any change to conform the Indenture to this prospectus will not be deemed to adversely affect such legal rights; in the case of the Indenture, to comply with the requirements of the SEC to qualify or maintain the qualification of the Indenture under the Trust Indenture Act; to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee; to add any additional Events of Default; or to secure the Notes and/or the Guarantees.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

No director, officer, employee, incorporator or stockholder or other Equity Interest holder, as such, of the Issuer or any Guarantor will have any liability for any obligations of the Issuer under the Notes or the Indenture or of any Guarantor under its Note Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Note Guarantees. The waiver may not be effective to waive liabilities under the federal securities laws.

CONCERNING THE TRUSTEE

The Bank of New York Mellon Trust Company, N.A. is the Trustee under the Indenture and has been appointed by the Issuer as Registrar and Paying Agent with regard to the Notes. The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Issuer, to obtain payment of claims in certain cases, or to realize on certain assets received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest (as defined in the Indenture) after a Default has occurred and is continuing, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

The Holders of a majority in aggregate principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions. In case an Event of Default occurs and is not cured, the Trustee will be

44

required, in the exercise of its power, to use the degree of care of a prudent person in similar circumstances in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holder, unless such Holder shall have offered to the Trustee security or indemnity satisfactory to the Trustee.

The Indenture, the Notes and the Note Guarantees are governed by, and construed in accordance with, the laws of the State of New York.

(2) if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate or other rates, then the interest rate deemed to have been in effect during the Four-Quarter Period will be the average of (a) the rate of interest on this Indebtedness in effect on the Transaction Date after giving effect to any Hedging Obligations then in effect and (b) the average of what the applicable rates would have been as of the last day of each of the six months immediately preceding the Transaction Date; and

(3) any Person that is or will become a Restricted Subsidiary on the Transaction Date will be deemed to be a Restricted Subsidiary at all times during the Four-Quarter Period and any Person that is not, and will not become, a Restricted Subsidiary on the Transaction Date will be deemed not to have been a Restricted Subsidiary at any time during such Four-Quarter Period.

(3) the net payments associated with interest rate Hedging Obligations,

(4) amortization of debt issuance costs, debt discount or premium (provided that any amortization of bond premium will be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such amortization of bond premium has otherwise reduced Consolidated Interest Expense) and other financing fees and expenses,

(5) the interest component of any deferred payment obligations,

(6) all other non-cash interest expense,

(7) capitalized interest,

(8) the product of (a) all dividend payments on any series of Disqualified Equity Interests of the Issuer or any Preferred Stock of any Restricted Subsidiary (other than any such Disqualified Equity Interests or any Preferred Stock held by the Issuer or a Wholly-Owned Restricted Subsidiary), multiplied by (b) a fraction, the numerator of which is one and the denominator of which is one minus the then current combined federal, state and local statutory tax rate of the Issuer and the Restricted Subsidiaries, expressed as a decimal,

(3) the net income of any Restricted Subsidiary during such period to the extent that the declaration or payment of dividends or similar distributions by such Restricted Subsidiary of that income is not permitted, directly or indirectly by any means, by operation of the terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule or governmental regulation applicable to that Restricted Subsidiary during such period, except that the Issuer’s equity in a net loss of any such Restricted Subsidiary for such period shall be included in determining Consolidated Net Income;

BOOK-ENTRY, DELIVERY AND FORM OF SECURITIES

The Regulation D Notes are currently represented by certificates. Upon a resale of Regulation D Notes pursuant to this registration statement, the Regulation D Notes will be represented by one or more global notes (the “Global Notes”) in definitive form. The Global Notes will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee of DTC (such nominee being referred to herein as the “Global Note Holder”). DTC will maintain the Notes through its book-entry facilities.

DTC has advised the Issuer as follows:

DTC is a limited-purpose trust company that was created to hold securities for its participating organizations, including Euroclear and Clearstream (collectively, the “Participants” or the “Depositary’s Participants”), and to facilitate the clearance and settlement of transactions in these securities between Participants through electronic book-entry changes in accounts of its Participants. The Depositary’s Participants include securities brokers and dealers (including the initial purchaser), banks and trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies (collectively, the “Indirect Participants” or the “Depositary’s Indirect Participants”) that clear through or maintain a custodial relationship with a Participant, either directly or indirectly. Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Depositary’s Participants or the Depositary’s Indirect Participants. Pursuant to procedures established by DTC, ownership of the Notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the interests of the Depositary’s Participants) and the records of the Depositary’s Participants (with respect to the interests of the Depositary’s Indirect Participants).

The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer the Notes will be limited to such extent.

So long as the Global Note Holder is the registered owner of any Notes, the Global Note Holder will be considered the sole Holder of outstanding Notes represented by such Global Notes under the Indenture. Except as provided below, beneficial owners of Notes will not be entitled to have Notes registered in their names and will not be considered the owners or holders thereof under the Indenture for any purpose, including with respect to the giving of any directions, instructions, or approvals to the Trustee thereunder. None of the Issuer, the Guarantors or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of Notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to such Notes.

Payments in respect of the principal of, premium, if any, and interest on any Notes registered in the name of a Global Note Holder on the applicable record date will be payable by the Trustee to or at the direction of such Global Note Holder in its capacity as the registered holder under the Indenture. Under the terms of the Indenture, the Issuer, the Guarantors and the Trustee may treat the Persons in whose names any Notes, including the Global Notes, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, neither the Issuer, the Guarantors nor the Trustee has or will have any responsibility or liability for the payment of such amounts to beneficial owners of Notes (including principal, premium, if any, and interest). The Issuer believes, however, that it is currently the policy of DTC to immediately credit the accounts of the relevant Participants with such payments, in amounts proportionate to their respective beneficial interests in the relevant security as shown on the records of DTC. Payments by the Depositary’s Participants and the Depositary’s Indirect Participants to the beneficial owners of Notes will be governed by standing instructions and customary practice and will be the responsibility of the Depositary’s Participants or the Depositary’s Indirect Participants.

If (1) the Depositary notifies the Issuer in writing that DTC is no longer willing or able to act as a depositary and the Issuer is unable to locate a qualified successor within 90 days or (2) there has occurred and

62

is continuing a Default and DTC notifies the Trustee of its decision to exchange the Global Note for Notes in definitive form under the Indenture, then, upon surrender by the relevant Global Note Holder of its Global Note, Notes in such form will be issued to each Person that such Global Note Holder and DTC identify as being the beneficial owner of the related Notes. Upon any such issuance, the Trustee is required to register such Notes in the name of and cause the same to be delivered to, such person or persons (or the nominee of any thereof). Such Notes would be issued in fully registered form and would be subject to the legal requirements described in this prospectus.

Neither the Issuer nor the Trustee will be liable for any delay by the Global Note Holder or DTC in identifying the beneficial owners of Notes and the Issuer and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Global Note Holder or DTC for all purposes.

Material U.S. federal income tax consequences

The following describes the material U.S. federal income tax consequences of the ownership and disposition of the notes by holders who purchase notes for a price equal to the issue price of the notes and who hold the notes as capital assets (generally, property held for investment). This discussion is not a complete discussion of all the potential tax consequences that may be relevant to you. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations thereunder, published rulings and court decisions, all as in effect on the date of this document, and all of which are subject to change, possibly on a retroactive basis, or are subject to different interpretations.

The tax treatment of holders of the notes may vary depending upon their particular situations. Certain holders, including insurance companies, tax exempt organizations, financial institutions, investors in pass-through entities, certain U.S. expatriates, taxpayers subject to the alternative minimum tax, broker-dealers and persons holding the notes as part of a “straddle,” “hedge” or “conversion transaction,” may be subject to special rules not discussed below. This discussion does not address any estate, gift, foreign, state or local tax considerations.

We urge you to consult your own tax advisors regarding the particular U.S. federal income tax consequences to you of holding and disposing of notes, any tax consequences that may arise under the laws of any relevant foreign, state, local, or other taxing jurisdiction or under any applicable tax treaty, as well as possible effects of changes in federal or other tax laws.

In certain circumstances (see “Description of the notes — Optional redemption”, and “— Change of control”), we may elect or be obligated to pay amounts on the notes that are in excess of stated interest or principal on the notes. We do not intend to treat the possibility of paying such additional amounts as causing the notes to be treated as “contingent payment debt instruments.” However, additional income will be recognized if any such additional payment is made. It is possible that the IRS may take a different position, in which case a holder might be required to accrue interest income at a higher rate than the stated interest rate and to treat as ordinary interest income any gain realized on the taxable disposition of the note. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. Investors should consult their own tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes.

U.S. HOLDERS

The following is a summary of the material U.S. federal income tax consequences that will apply to you if you are a U.S. holder of the notes. For purposes of this discussion, you are a “U.S. holder” if you are a beneficial owner of notes and you are:

•  an individual citizen or resident alien of the United States;

•  a corporation or other entity subject to tax as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or of any state thereof or the District of Columbia;

63

•  an estate whose income is subject to U.S. federal income taxation regardless of its source; or

•  a trust if a U.S. court is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or a trust that has a valid election in effect under applicable regulations to be treated as a United States person.

If a partnership or other entity treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner will generally depend on the status of the partner and on the activities of the partnership. Partners of partnerships holding notes should consult their tax advisors.

Stated interest on the notes

Stated interest on the notes generally will be taxable to you as ordinary income at the time it is received or accrued in accordance with your regular method of accounting for United States federal income tax purposes.

Sale, taxable exchange, redemption, retirement or other taxable disposition of the notes

Upon a sale, taxable exchange, redemption, retirement or other taxable disposition of a note, you generally will recognize gain or loss equal to the difference between the amount received upon such disposition (less any amount attributable to accrued interest which will be taxable as ordinary income, if not previously included in gross income) and your adjusted tax basis in the note at that time. Your adjusted tax basis in the note will generally equal the amount you paid for the note. Such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of the disposition, the note has been held for more than one year. Under current law, long-term capital gains of certain non-corporate holders are generally taxed at lower rates than items of ordinary income. The deductibility of capital losses is subject to limitations.

Backup withholding and information reporting

In general, information reporting and backup withholding will apply to payments of interest on the notes and to the proceeds from the sale, redemption, retirement or other disposition of a note paid to you if you fail to provide the withholding agent with a correct taxpayer identification number, certified under penalties of perjury, as well as certain other information. Backup withholding is not an additional tax. If backup withholding applies to you, you may use the amounts withheld as a refund or credit against your U.S. federal income tax liability, as long as you timely provide certain information to the Internal Revenue Service, which we refer to as the IRS.

New legislation

For taxable years beginning after December 31, 2012, newly enacted legislation is scheduled to impose a 3.8% tax on the “net investment income” of certain United States citizens and resident aliens, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” would generally include gross income from interest and net gain from the sale, redemption, exchange, retirement or other taxable disposition of a note, less certain deductions.

NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax consequences that will apply to you if you are a non-U.S. holder of the notes. You are a “non-U.S. holder” for purposes of this discussion if you are a beneficial owner of notes that is an individual, corporation, estate or trust that is not a U.S. holder.

64

Stated interest on the notes

Stated interest that we pay to you that is not effectively connected with your conduct of a U.S. trade or business will not be subject to U.S. federal income tax and U.S. federal withholding tax will not be required on that payment if you:

•  do not actually or constructively own 10% or more of the combined voting power of all classes of our stock;

•  are not a controlled foreign corporation with respect to which we are a related person;

•  are not a bank receiving interest on a loan entered into in the ordinary course of business within the meaning of the Code; and

•  you certify to us, our payment agent, or the person who would otherwise be required to withhold U.S. federal income tax, on IRS Form W-8BEN or applicable substitute form, under penalties of perjury, that you are not a United States person and provide your name and address.

If you do not satisfy the preceding requirements, your interest on a note that is not effectively connected with a U.S. trade or business would generally be subject to U.S. withholding tax at a flat rate of 30% unless that rate is reduced or eliminated pursuant to an applicable tax treaty (provided certain certification requirements are met).

Sale, taxable exchange, redemption, retirement or other taxable disposition of the notes

You generally will not be subject to U.S. federal income tax with respect to gain recognized on a sale, taxable exchange, redemption, retirement or other taxable disposition of a note unless:

•  the gain is effectively connected with your conduct of a trade or business within the United States, and, if an applicable income tax treaty applies, is attributable to a permanent establishment or fixed base you maintain in the United States; or

•  you are an individual who is present in the United States for 183 or more days in the taxable year of the disposition and certain other requirements are met.

If you are a non-U.S. holder described in the first bullet point above, you generally will be subject to tax as described below (See “— Non-U.S. holders — Income or gain effectively connected with a U.S. trade or business”). If you are a non-U.S. holder described in the second bullet point above, you generally will be subject to a flat 30% United States federal income tax on the gain derived from the sale, redemption, exchange, retirement or other disposition, which may be offset by certain United States source capital losses.

Income or gain effectively connected with a U.S. trade or business

If you are engaged in trade or business in the United States, and if interest on a note or gain on the sale, taxable exchange, redemption, retirement or other taxable disposition of a note is effectively connected with the conduct of that trade or business (and, if an applicable income tax treaty so requires, is attributable to a permanent establishment or fixed base maintained by you in the United States), you will be subject to regular U.S. federal income tax on the interest or gain in the same manner as if you were a United States person but will be exempt from U.S. withholding tax if you provide to us, our payment agent or the person who would otherwise be required to withhold U.S. federal income tax, a properly completed and executed IRS Form W-8ECI or applicable substitute form. In addition to regular U.S. federal income tax, if you are a corporation, you may be subject to a U.S. branch profits tax at a 30% rate or such lower rate as may be available under an applicable income tax treaty.

Information reporting and backup withholding

Backup withholding and information reporting generally will not apply to payments to you of interest on the notes by us or our paying agent to you if you certify as to your non-U.S. status under penalties of perjury or otherwise establish an exemption, provided that neither we nor our paying agent has actual knowledge or

65

reason to know that you are a United States person or that the conditions of any other exemptions are not in fact satisfied. However, payments of interest on the notes are required to be reported on IRS Form 1042-S even if the payments are not otherwise subject to information reporting.

The payments of the proceeds of the disposition of notes to or through the U.S. office of a U.S. or foreign broker will be subject to information reporting and backup withholding unless you provide the certification described above under “— Non-U.S. holders — Stated interest on the notes” or otherwise establish an exemption. The proceeds of a disposition of notes effected outside the United States to or through a foreign office of a broker generally will not be subject to backup withholding or information reporting. However, if that broker is a United States person, a controlled foreign corporation for U.S. tax purposes, a foreign person 50% or more of whose gross income from all sources for certain periods is effectively connected with a trade or business in the United States, or a foreign partnership that is engaged in the conduct of a trade or business in the United States or that has one or more partners that are U.S. persons who in the aggregate hold more than 50% of the income or capital interests in the partnership, information reporting requirements will apply unless that broker has documentary evidence in its files of your non-U.S. status and has no actual knowledge or reason to know to the contrary or unless you otherwise establish an exemption.

You are urged to consult your tax advisors regarding the application of information reporting and backup withholding to your particular situation, the availability of an exemption therefrom, and the procedure for obtaining such an exemption, if available. Any amounts withheld from a payment to you under the backup withholding rules will be allowed as a credit against your U.S. federal income tax liability, if any, and may entitle you to a refund, provided you timely furnish the required information to the IRS.

TREASURY CIRCULAR 230 DISCLOSURE

The preceding discussion of material U.S. federal income tax considerations and any other discussion in this prospectus of the tax consequences or tax risks of an investment in the notes is not intended or written to be used, and cannot be used, by any person for the purpose of avoiding tax penalties that may be imposed on the person. This discussion was written to support the marketing of the transaction(s) or matter(s) addressed herein, and the taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor. No limitation has been imposed by legal counsel on disclosure of the tax treatment or tax structure of the transaction.

Plan of distribution

The Regulation D Notes may be sold from time to time directly by the selling noteholders or alternatively, through underwriters, broker-dealers or agents. If the Regulation D Notes are sold through underwriters, broker-dealers or agents, the applicable selling noteholder will be responsible for underwriting discounts or commissions or broker-dealer’s or agent’s commissions, or similar charges, and fees. Such notes may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale, or at negotiated prices. Such sales may be effected in transactions (which may involve block transactions) (1) on any national securities exchange or quotation service on which the notes may be listed or quoted at the time of sale, (2) in the over-the-counter market or (3) in transactions otherwise than on such exchanges or services or in the over-the-counter market.

The aggregate proceeds to the selling noteholders from the sale of the Regulation D Notes will be the purchase price of the Regulation D Notes less discounts and commissions, if any. Each of the selling noteholders, together with their agents from time to time, reserves the right to accept and to reject, in whole or in part, any proposed purchase of Regulation D Notes directly or through agents. We will not receive any of the proceeds from the sale by the selling noteholders of the Regulation D Notes.

We have no plans to list the notes on a securities exchange and can give no assurance about the development of any trading market for the notes. See “Risk factors — Risks Related to the Notes.”
