PROSPECTUS SUMMARY

        In this prospectus, the words "we," "us," "our," and "the Company" refer to Tutor Perini Corporation, the issuer of the exchange notes, and its subsidiaries. The following summary contains basic information about the Company and this exchange offer. It is not complete and may not contain all the information that may be important to you. You should carefully read the entire prospectus and the documents incorporated by reference, before making an investment decision, especially the information presented under the heading "Risk Factors," our financial statements, the notes to those financial statements and the other financial information, included elsewhere in this prospectus.

Our Company

        We are a leading construction services company offering diversified general contracting, construction management and design-build services to private clients and public agencies throughout the world. Based on our 2009 revenues, the Company was ranked by Engineering News Record ("ENR") as the 9^th largest contractor in the U.S. market. We have provided construction services since 1894 and have established a strong reputation within our markets by executing large, complex projects on time and within budget while adhering to strict quality control measures. We offer general contracting, pre-construction planning and comprehensive project management services, including the planning and scheduling of the manpower, equipment, materials and subcontractors required for a project. We also offer self-performed construction services including site work, concrete forming and placement, steel erection, electrical and mechanical, plumbing and HVAC. During 2010, we performed work on approximately 300 construction projects for over 145 federal, state and local government agencies or authorities and private customers. For the year ended December 31, 2010, we generated revenues and net income of $3,199.2 million and $103.5 million, respectively.

        We have executed a number of transactions in the past to diversify our business and geographic profile. In January 2003, the acquisition of James A. Cummings, Inc. ("Cummings") expanded our presence in the southeastern region of the United States. Cummings specializes in the construction of schools, municipal buildings and commercial developments. In January 2005, we acquired Cherry Hill Construction ("Cherry Hill"), a regional civil construction company who operates in the mid-Atlantic and southeastern regions. Cherry Hill provided the Company with more geographic coverage and expanded the equipment fleet. Rudolph and Sletten, Inc. ("Rudolph and Sletten"), an established building contractor and construction management company based in Redwood City, California, was acquired in October 2005 to expand our presence on the west coast of the United States. Rudolph and Sletten specializes in the construction of corporate campuses and healthcare, gaming, biotech, pharmaceutical, industrial, and high-tech projects. In September 2008, we merged with Tutor-Saliba Corporation ("Tutor Saliba") to further expand our presence in the western United States. Tutor-Saliba is an established general contractor with expertise in both civil and building projects, including highways, bridges, mass transit systems, hospitality and gaming, transportation, healthcare, education and office building projects, primarily in Nevada and California for both public and private customers. In January 2009, we acquired Keating Building Company ("Keating"), a Philadelphia-based construction, construction management and design-build company with expertise in both private and public works building projects. The acquisition of Keating enabled us to expand our building construction market presence in the eastern half of the United States, including the northeast and mid-Atlantic regions. In November 2010, we acquired Superior Gunite, a California-based construction company specializing in pneumatically placed structural concrete utilized primarily in infrastructure projects such as bridges, dams, tunnels and retaining walls. In January 2011, we completed the acquisition of Fisk Electric Company ("Fisk"), an electrical construction company based in Houston, Texas. Fisk covers many of the major commercial and industrial electrical construction markets in the southwest and southeast regions, with the ability to cover other attractive markets nationwide. We acquired Fisk because we believe that Fisk is a strong strategic fit enabling us to expand our nationwide

electrical capabilities and to realize significant synergies and opportunities in support of our non-residential building and civil operations. In April 2011, we acquired Anderson Companies which provides general contracting, design-build, preconstruction, and construction management services throughout the Southeastern United States.

        Our business is currently organized into three segments: Building, Civil and Management Services:

        Building Group:    Our Building segment has significant experience providing services to a number of specialized building markets, including the hospitality and gaming, transportation, healthcare, municipal offices, sports and entertainment, education, correctional facilities, and other industrial markets. We have a leading reputation for executing the largest and most complex non-residential building projects, with strict adherence to superior quality control and timely execution. In 2010, we earned the following rankings from Engineering-News Record, based on revenue:

•

2nd largest contractor in the United States general building market



•

Largest builder in the hotel, motel and convention center market



•

Largest builder in the entertainment facilities market



•

2nd largest builder in the airport facilities market



•

12th largest builder in the healthcare market



•

2nd largest green building contractor in the United States

Additionally, we are currently working on or recently completed a number of marquee projects, including, but not limited to:

•

McCarran Airport Terminal 3 in Las Vegas, NV



•

Philadelphia Convention Center in Pennsylvania



•

Children's Hospital in Los Angeles, CA



•

CityCenter for MGM Mirage in Las Vegas, NV



•

Wynn Encore Hotel in Las Vegas, NV

        For the year ended December 31, 2010, our Building segment generated revenues and income from construction operations of $2,327 million and $95.9 million, respectively. As of December 31, 2010, our Building segment backlog was approximately $2.7 billion.

        Civil Group:    Our Civil segment specializes in public works construction and the repair, replacement and reconstruction of infrastructure, primarily in the western, northeastern and mid-Atlantic United States. Services include the construction and rehabilitation of highways, bridges, mass transit systems, and wastewater treatment facilities. Due to the 2009 multi-billion dollar economic stimulus package, the increase in alternative funding sources such as public-private partnerships and historically large government funding sources aimed at the replacement and repair of an aging U.S. infrastructure, we believe this segment provides substantial growth opportunities for us in the future. In 2010, we earned the following rankings from Engineering-News Record, based on revenue:

•

9^th largest domestic heavy contractor



•

9^th largest transportation contractor



•

20^th largest builder of bridges

        Additionally, we have completed or are currently working on some of the most significant civil projects in the United States, including, but not limited to:

•

SR99 bored tunnel project in Seattle, WA



•

Rehabilitation of the Tappan Zee bridge in Westchester County, NY



•

John F. Kennedy International Airport runway widening in Queens, NY



•

Various segments of the Greenwich Street corridor project in New York, NY



•

I-5 bridge replacement in Shasta County, CA



•

Caldecott Tunnel project near Oakland, CA



•

New Irvington Tunnel project in Fremont, CA



•

Construction of express toll lanes along I-95 in Maryland

        For the year ended December 31, 2010, our civil segment generated revenues and income from construction operations of $668 million and $87.8 million, respectively. As of December 31, 2010, our civil segment backlog was approximately $1.4 billion.

        Management Services:    Our Management Services segment provides diversified construction and design-build services to the U.S. military and government agencies as well as surety companies and multi-national corporations in the United States and overseas. This segment has historically focused on regions such as Iraq and Afghanistan, with additional growth opportunities in Guam, as the U.S. military plans to expand its presence in that region. For the year ended December 31, 2010, our Management Services segment generated revenues and income from construction operations of $205 million and $22.2 million, respectively. As of December 31, 2010, our Management Services backlog was $261 million.

Competitive Strengths

        Significant scale and leading construction capabilities.    We believe that our national network of construction and management services differentiates us from our competitors, specifically in end markets that require complex solutions. For over 100 years, we have provided specialized construction services, with an emphasis on large, complex projects in dense urban areas. We consistently qualify to compete for major projects across the United States due to our proven record of performance and strong financial position. We have completed or are currently working on some of the most significant construction projects in the United States, including McCarran International Airport Terminal 3 in Las Vegas, NV, Philadelphia Convention Center in Philadelphia, PA, San Bernardino Courthouse in San Bernardino, CA, Tappan Zee Bridge in Westchester County, New York; and the John F. Kennedy International Airport runway widening in Queens, New York. Our nationwide capabilities, long-term client relationships and proven expertise allow us to capture additional business from existing clients seeking to expand their geographic or local presence and market share. We continue to successfully leverage our nationwide capabilities to assist our clients across all geographic regions.

        Integrated business model with significant self perform capabilities.    Our self-perform construction services include site work, concrete forming and placement, steel erection, electrical and mechanical, plumbing and HVAC. Certain of our existing and potential customers, especially those in the civil end markets, require general contractors to perform significant portions of the construction process without the use of subcontractors. While many of our competitors subcontract a significant portion of a project, our integrated business model enables us to keep a larger portion of the work in-house.

        This ability, along with our financial strength and outstanding record of performance on challenging building and civil works projects, prequalifies us for projects in situations where smaller,

3

Table of Contents

less diversified contractors are unable to do so. This is a competitive advantage that makes us an attractive partner on the largest infrastructure projects and DBOM (design-build-operate-maintain) contracts, which combine the nation's top contractors with engineering firms, equipment manufacturers and project development consultants in a competitive bid selection process to execute highly sophisticated public works projects.

        Revenue that is diversified across customers and end markets.    Our construction services are targeted toward end markets that are diversified across project types, client characteristics and geographic locations. Our Building segment includes revenue sources from the hospitality and gaming, transportation, healthcare, municipal and government, education, commercial offices, sports and entertainment and industrial end markets. In 2010, $2.3 billion of revenue came from end markets served by our Building segment. Our Civil segment revenue comes from a number of different project types, including bridges, mass transit, highways and wastewater treatment projects. In 2010, we generated $668 million of revenue from end markets served by our Civil Group segment.

        In addition to providing our services across a number of different end markets, we provide our services to a broad range of private and public customers. In 2010, we derived approximately 47% of our revenues from private customers. Our private customers include major hospitality and gaming resort owners, Native American sovereign nations, public corporations, private developers, healthcare companies and private universities. We derived approximately 44% of our revenues from state and local government customers during 2010. Our state and local government customers include state transportation departments, metropolitan authorities, cities, municipal agencies, school districts and public universities. We derived approximately 9% of our revenues from federal governmental agencies during 2010. These agencies have included the U.S. State Department, the U.S. Navy, the U.S. Army Corps of Engineers, and the U.S. Air Force.

        Substantial backlog that provides a significant base of new project opportunities.    We believe our substantial backlog of uncompleted construction work provides us with visibility into our future performance. We include a construction project in our backlog at such time as a contract is awarded or a letter of commitment is obtained and adequate construction funding is in place. As a result, we believe the backlog figures are firm, subject only to the cancellation provisions contained in the various contracts. Historically, these provisions have not had a material adverse effect on us.

        As of December 31, 2010 we had a construction backlog of $4.3 billion, consistent with a backlog of $4.3 billion at December 31, 2009 and compared to $6.7 billion at December 31, 2008. We estimate that approximately $2.2 billion or 51% of our backlog at December 31, 2010 will not be completed in 2011. In addition, we have pending awards and prospects for both public and private sector customers that could enter backlog in the near future.

        Experienced, proven management team and highly skilled workforce.    Our senior management team and workforce bring significant industry work experience and specialized project expertise to our project operations. Our senior executive management team has an average of more than 30 years of industry experience having spent most of their careers with our company. Under the current management team's leadership, we have grown our revenues and income, while significantly diversifying our revenue base into new end markets and geographies.

Our Business Strategy

        We are committed to our tradition of providing high-quality construction services to both public and private agencies throughout the world, while increasing value to our shareholders. Major elements of our business strategy are as follows:

        Seek large civil construction projects throughout the United States.    We believe the Civil segment provides significant opportunities for growth due to an aging U.S. infrastructure. More than $2.2 trillion

of construction spending is needed over the next five years to bring the nation's infrastructure into a state of good repair. In addition to existing funding for public work programs, the multi-billion dollar economic stimulus package approved by the U.S. government in 2009 provides substantial funding for civil construction, public healthcare and public education projects over the next several years. We have been active in civil construction since 1894 and have expertise in large, complex civil construction projects and are currently pursuing some of the most significant projects across the U.S.

        Continue to leverage our core competencies to obtain profitable contracts within our Building segment.    Our construction business involves making significant estimates and assumptions in the normal course of business relating to our contracts and our joint venture contracts. Our cost estimates of contracts are highly detailed. We believe our success within the Building segment results from our proven ability to manage and perform large, complex projects with aggressive fast-track schedules, while providing accurate budgeting forecasts and strict quality control. Our reputation for completing projects on time and within budget is a significant competitive advantage within the markets in which we operate. We will continue to leverage this competitive advantage as we pursue all types of building projects, including public works opportunities.

        Pursue expansion opportunities within the Management Services segment.    Black Construction, one of our subsidiaries and the largest contractor on the island of Guam, is expected to generate a significant portion of its future revenues from the construction of facilities during the planned expansion of the United States military's presence in Guam. This is one of several programs expected to generate over $10 billion in construction spending in Guam over the next five years. In addition, we believe we are well positioned to capture additional management services projects that involve long-term contracts and provide a recurring source of revenues as the level of government expenditures for defense and homeland security has increased in response to the global threat of terrorism. We have proven our ability to meet challenging demands with various U.S. government agencies and intend to leverage this proficiency to secure additional contracts going forward.

        Strategically evaluate acquisitions.    Our management team is focused on continuing to pursue acquisitions across all of our business segments as part of our growth strategy. We have demonstrated past success with the integration of numerous companies, including Tutor-Saliba, James A. Cummings, Inc., Cherry Hill Construction, Inc., Rudolph and Sletten, Inc. and Keating Building Corporation. In November 2010 and January 2011, we acquired Superior Gunite and Fisk Electric Company, respectively, in an effort to achieve greater vertical integration and higher margins by increasing the percentage of work we self-perform in our building and civil operations. We continue to actively identify and screen potential acquisition targets to enhance our geographic presence and strengthen our self performance capabilities.

The Exchange Offer

        On October 20, 2010, we sold, through a private placement exempt from the registration requirements of the Securities Act, $300,000,000 of our 7⁵/8% Senior Notes due 2018, all of which are eligible to be exchanged for Exchange Notes. We refer to these notes as "Old Notes" in this prospectus.

        Simultaneously with the private placement, we entered into a registration rights agreement with the initial purchasers of the Old Notes (the "Registration Rights Agreement"). Under the Registration Rights Agreement, we are required to use our reasonable best efforts to cause a registration statement for substantially identical notes, which will be issued in exchange for the Old Notes, to be filed with the Securities and Exchange Commission ("SEC") and to complete the exchange offer within 365 days after the issue date of the Old Notes. We refer to the notes to be registered under this exchange offer registration statement as "Exchange Notes" and collectively with the Old Notes, we refer to them as the "notes" in this prospectus. You may exchange your Old Notes for Exchange Notes in this exchange offer. You should read the discussion under the headings "—Summary of Exchange Offer," "Exchange Offer" and "Description of Exchange Notes" for further information regarding the Exchange Notes.

Consequences of Not Exchanging Old Notes

        If you do not exchange your Old Notes in the exchange offer, your Old Notes will continue to be subject to the restrictions on transfer currently applicable to the Old Notes. In general, you may offer or sell your Old Notes only:

•

if they are registered under the Securities Act and applicable state securities laws;

RISK FACTORS

        You should carefully consider the risk factors set forth below as well as the other information contained in, and incorporated by reference in, this prospectus before deciding whether to participate in the exchange offer. The risks described below are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our fiscal condition, results of operations and cash flows. Any of the following risks could materially adversely affect our business, financial condition or results of operations. In such case, you may lose all or part of your original investment. Along with the risks and uncertainties described below, you should carefully consider the risks and uncertainties described in the section entitled "Risk factors" in our 2010 Form 10-K, which are incorporated by reference into this prospectus.

Risks Related to the Exchange Offer and Holding the Exchange Notes

We have a substantial amount of indebtedness which could adversely affect our financial position and prevent us from fulfilling our obligations under the notes.

        We currently have, and upon consummation of the exchange offer, will continue to have, a substantial amount of indebtedness. We may also incur significant additional indebtedness in the future. Our substantial indebtedness may:

•

make it difficult for us to satisfy our financial obligations, including making scheduled principal and interest payments on the notes and our other indebtedness;



•

limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other general business purposes;



•

limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, acquisitions or other general business purposes;



•

require us to use a substantial portion of our cash flow from operations to make debt service payments;



•

limit our flexibility to plan for, or react to, changes in our business and industry;



•

place us at a competitive disadvantage compared to our less leveraged competitors; and



•

increase our vulnerability to the impact of adverse economic and industry conditions.

Despite our current level of indebtedness, we may still be able to incur substantially more indebtedness. This could exacerbate the risks associated with our substantial indebtedness.

        We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indenture limits, but does not prohibit, us or our subsidiaries from incurring additional indebtedness. If we incur any additional indebtedness that ranks equally with the notes and the guarantees, the holders of that indebtedness will be entitled to share ratably with the holders of the notes and the guarantees in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us. This may have the effect of reducing the amount of proceeds paid to you. If new indebtedness is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the notes.

        Any default under the agreements governing our indebtedness, including a default under our senior secured revolving credit facility that is not waived by the required lenders, and the remedies

sought by the holders of such indebtedness could prohibit us from making payments of principal, premium, if any, or interest on the notes and could substantially decrease the market value of the notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, or interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness (including our senior secured revolving credit facility), we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest. More specifically, the lenders under our senior secured revolving credit facility could elect to terminate their commitments, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy, if applicable to us, or liquidation. If our operating performance declines, we may in the future need to seek waivers from the required lenders under the senior secured revolving credit facility to avoid being in default. If we breach covenants under our senior secured revolving credit facility and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under the revolving credit facility, the lenders could exercise their rights as described above, and we could be forced into bankruptcy, to the extent applicable to us, or liquidation. No assurance can be given that, if we breach covenants under our revolving credit facility and our creditors seek to enforce their rights under the federal bankruptcy laws, that a forum will be available to creditors. See "Description of Other Indebtedness" and "Description of Exchange Notes."

The lenders under our senior secured revolving credit facility will have the discretion to release the guarantors under the revolving credit facility in a variety of circumstances which will cause those guarantors to be released from their guarantees of the notes.

        While any obligations under our senior secured revolving credit facility remain outstanding, any guarantee of the notes may be released without action by, or consent of, any holder of the notes or the trustee under the indenture governing the notes offered hereby if the related guarantor is no longer a guarantor of the obligations under the revolving credit facility. See "Description of Exchange Notes—Guarantees." The lenders under the revolving credit facility will have the discretion to release the guarantees under the revolving credit facility in a variety of circumstances. You will not have a claim as a creditor against any subsidiary that is no longer a guarantor of the notes.

The Exchange Notes and the guarantees will be unsecured and effectively subordinated to our and the guarantors' existing and future secured indebtedness.

        The Exchange Notes and the guarantees will be general unsecured obligations ranking effectively junior in right of payment to all of our existing and future secured indebtedness and that of each guarantor, including indebtedness under our senior secured revolving credit facility. Additionally, the indenture governing the Exchange Notes will permit us to incur additional secured indebtedness in the future. In the event that we or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any indebtedness that is effectively senior to the Exchange Notes and the guarantees will be entitled to be paid in full from our assets or the assets of the guarantor, as applicable, securing such indebtedness before any payment may be made with respect to the Exchange Notes or the affected guarantees. Holders of the Exchange Notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the Exchange Notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets.

Claims of noteholders will be structurally subordinate to claims of creditors of our subsidiaries that do not guarantee the notes.

        The Exchange Notes will not be guaranteed by our non U.S. subsidiaries and certain future subsidiaries that we designate as "unrestricted" in accordance with the terms of the indenture. Accordingly, claims of holders of the Exchange Notes will be structurally subordinated to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of these subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the Exchange Notes. In the event of the liquidation, dissolution, reorganization, bankruptcy or similar proceeding of the business of a subsidiary that is not a guarantor, creditors of that subsidiary would generally have the right to be paid in full before any distribution is made to us or the holders of the Exchange Notes. In any of these events, we may not have sufficient assets to pay amounts due on the Exchange Notes with respect to the assets of that subsidiary.

A subsidiary guarantee could be voided if it constitutes a fraudulent transfer under U.S. bankruptcy or similar state law, which would prevent the holders of the notes from relying on that subsidiary to satisfy claims.

        Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee can be voided, or claims under the guarantee may be subordinated to all other debts of that guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee or, in some states, when payments become due under the guarantee, received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and:

•

was insolvent or rendered insolvent by reason of such incurrence;



•

was engaged in a business or transaction for which the guarantor's remaining assets constituted unreasonably small capital; or



•

intended to incur, or believed that it would incur, debts beyond its ability to pay those debts as they mature.

        A guarantee may also be voided, without regard to these factors, if a court finds that the guarantor entered into the guarantee with the actual intent to hinder, delay or defraud its creditors. A court would likely find that a guarantor did not receive reasonably equivalent value or fair consideration for its guarantee if the guarantor did not substantially benefit directly or indirectly from the issuance of the guarantees. If a court were to void a guarantee, you would no longer have a claim against the guarantor. Sufficient funds to repay the notes may not be available from other sources, including the remaining guarantors, if any. In addition, the court might direct you to repay any amounts that you already received from the subsidiary guarantor.

        The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law. Generally, a guarantor would be considered insolvent if:

•

the sum of its debts, including contingent liabilities, were greater than the fair saleable value of all its assets;



•

the present fair saleable value of its assets is less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or



•

it could not pay its debts as they become due.

        Each subsidiary guarantee will contain a provision intended to limit the guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect the subsidiary

15

guarantees from being voided under fraudulent transfer law. In a recent Florida bankruptcy case, this kind of provision was found to be ineffective to protect the guarantees.

Upon a change of control, we may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes, which would violate the terms of the notes.

        Upon the occurrence of a change of control, holders of the notes will have the right to require us to purchase all or any part of the notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. We may not have sufficient financial resources available to satisfy all of obligations under the notes in the event of a change in control. Our failure to purchase the notes as required under the indenture would result in a default under the indenture and a cross-default under our senior secured revolving credit facility, each of which could have material adverse consequences for us and the holders of the notes. In addition, the revolving credit facility provides that a change of control is a default that permits lenders to accelerate the maturity of borrowings under it. See "Description of Exchange Notes—Change of Control."

Your ability to transfer the Exchange Notes offered hereby will be restricted and may be further limited by the absence of an active trading market.

        The Exchange Notes are a new issue of securities and there is no established trading market for them, or for the Old Notes. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for quotation on any automated dealer quotation system. You may not be able to sell your notes at a particular time or at favorable prices. As a result, we cannot assure you as to the liquidity of any trading market for the Exchange Notes or as to whether any market will develop or be maintained. Accordingly, you may be required to bear the financial risk of your investment in the Exchange Notes indefinitely. If a trading market were to develop, future trading prices of the Exchange Notes may be volatile and will depend on many factors, including:

•

the number of holders of Exchange Notes;



•

our operating performance and financial condition;



•

the market for similar securities;



•

the interest of securities dealers in making a market in the Exchange Notes; and



•

prevailing interest rates.

        Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of these securities. We cannot assure you that the market for the Exchange Notes will be free from similar disruptions. Any such disruptions could have an adverse effect on holders of the Exchange Notes.

Holders of Old Notes who fail to exchange their Old Notes in the exchange offer will continue to be subject to restrictions on transfer.

        If you do not exchange your Old Notes for Exchange Notes in the exchange offer, you will continue to be subject to the restrictions on transfer applicable to the Old Notes. The restrictions on transfer of your Old Notes arise because we issued the Old Notes under exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws. In general, you may only offer or sell the Old Notes if they are registered under the Securities Act and applicable state securities laws, or offered and sold under an exemption from these requirements. We do not plan to register the Old Notes under the Securities Act. For further information regarding the consequences of tendering your Old Notes in the exchange offer, see the discussion below under the caption "Exchange Offer—Consequences of Failure to Exchange."

Table of Contents

You must comply with the exchange offer procedures in order to receive new, freely tradable Exchange Notes.

        Delivery of Exchange Notes in exchange for Old Notes tendered and accepted for exchange pursuant to the exchange offer will be made only after timely receipt by the exchange agent of book-entry transfer of Old Notes into the exchange agent's account at DTC, as depositary, including an Agent's Message (as defined herein). We are not required to notify you of defects or irregularities in tenders of Old Notes for exchange. Exchange Notes that are not tendered or that are tendered but we do not accept for exchange will, following consummation of the exchange offer, continue to be subject to the existing transfer restrictions under the Securities Act and, upon consummation of the exchange offer, certain registration and other rights under the Registration Rights Agreement will terminate. See "Exchange Offer—Procedures for Tendering Old Notes" and "Exchange Offer—Consequences of Failure to Exchange."

Some holders who exchange their Old Notes may be deemed to be underwriters, and these holders will be required to comply with the registration and prospectus delivery requirements in connection with any resale transaction.

        If you exchange your Old Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes, you may be deemed to have received restricted securities and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

USE OF PROCEEDS

        This exchange offer is intended to satisfy our obligations under the Registration Rights Agreement. We will not receive any cash proceeds from the issuance of the Exchange Notes. In consideration for issuing the Exchange Notes contemplated in this prospectus, we will receive outstanding securities in like principal amount, the form and terms of which are substantially the same as the form and terms of the Exchange Notes, except as otherwise described in this prospectus. The Old Notes surrendered in exchange for the Exchange Notes will be retired and cancelled. Accordingly, no additional debt will result from the exchange offer. We will bear the expense of the exchange offer.

EXCHANGE OFFER

Purpose of the Exchange Offer

        The exchange offer is designed to provide holders of Old Notes with an opportunity to acquire Exchange Notes which, unlike the Old Notes, will be freely transferable at all times, subject to any restrictions on transfer imposed by state "blue sky" laws and provided that the holder is not our affiliate within the meaning of the Securities Act and represents that the Exchange Notes are being acquired in the ordinary course of the holder's business and the holder is not engaged in, and does not intend to engage in, a distribution of the Exchange Notes.

        The Old Notes were originally issued and sold on October 20, 2010, to the initial purchasers, pursuant to the purchase agreement dated October 15, 2010. The Old Notes were issued and sold in a transaction not registered under the Securities Act in reliance upon the exemption provided by Section 4(2) of the Securities Act. The concurrent resale of the Old Notes by the initial purchasers to investors was done in reliance upon the exemptions provided by Rule 144A and Regulation S promulgated under the Securities Act. The Old Notes may not be reoffered, resold or transferred other than (i) to us or our subsidiaries, (ii) to a qualified institutional buyer in compliance with Rule 144A promulgated under the Securities Act, (iii) outside the United States to a non-U.S. person within the meaning of Regulation S under the Securities Act, (iv) pursuant to the exemption from registration provided by Rule 144 promulgated under the Securities Act (if available) or (v) pursuant to an effective registration statement under the Securities Act.

        In connection with the original issuance and sale of the Old Notes, we entered into the Registration Rights Agreement, pursuant to which we agreed to file with the SEC a registration statement covering the exchange by us of the Exchange Notes for the Old Notes, pursuant to the exchange offer. The Registration Rights Agreement provides that we will file with the SEC an exchange offer registration statement on an appropriate form under the Securities Act and offer to holders of Old Notes who are able to make certain representations the opportunity to exchange their Old Notes for Exchange Notes.

        Under existing interpretations by the Staff of the SEC as set forth in no-action letters issued to third parties in other transactions, the Exchange Notes would, in general, be freely transferable after the exchange offer without further registration under the Securities Act; provided, however, that in the case of broker-dealers participating in the exchange offer, a prospectus meeting the requirements of the Securities Act must be delivered by such broker-dealers in connection with resales of the Exchange Notes. We have agreed to furnish a prospectus meeting the requirements of the Securities Act to any such broker-dealer for use in connection with any resale of any Exchange Notes acquired in the exchange offer. A broker-dealer that delivers such a prospectus to purchasers in connection with such resales will be subject to certain of the civil liability provisions under the Securities Act and will be bound by the provisions of the Registration Rights Agreement (including certain indemnification rights and obligations).

        We do not intend to seek our own interpretation regarding the exchange offer, and we cannot assure you that the staff of the SEC would make a similar determination with respect to the Exchange Notes as it has in other interpretations to third parties.

        Each holder of Old Notes that exchanges such Old Notes for Exchange Notes in the exchange offer will be deemed to have made certain representations, including representations that (i) any Exchange Notes to be received by it will be acquired in the ordinary course of its business, (ii) it has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of Exchange Notes and (iii) it is not our affiliate as defined in Rule 405 under the Securities Act, or if it is an affiliate, it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable.

Table of Contents

        If the holder is not a broker-dealer, it will be required to represent that it is not engaged in, and does not intend to engage in, the distribution of Old Notes or Exchange Notes. If the holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Old Notes that were acquired as a result of market-making activities or other trading activities, it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes.

Terms of the Exchange Offer; Period for Tendering Outstanding Old Notes

        Upon the terms and subject to the conditions set forth in this prospectus, we will accept any and all Old Notes that were acquired pursuant to Rule 144A or Regulation S validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date of the exchange offer. We will issue $1,000 principal amount of Exchange Notes in exchange for each $1,000 principal amount of Old Notes accepted in the exchange offer. Holders may tender some or all of their Old Notes pursuant to the exchange offer. However, Old Notes may be tendered only in integral multiples of $1,000.

        The form and terms of the Exchange Notes are the same as the form and terms of the outstanding Old Notes except that:

        (1)   the Exchange Notes will be registered under the Securities Act and will not have legends restricting their transfer;

        (2)   the Exchange Notes will not contain the registration rights and liquidated damages provisions contained in the outstanding Old Notes; and

        (3)   interest on the Exchange Notes will accrue from the last interest date on which interest was paid on your Old Notes.

The Exchange Notes will evidence the same debt as the Old Notes and will be entitled to the benefits of the Indenture.

        We intend to conduct the exchange offer in accordance with the applicable requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations of the SEC.

        We will be deemed to have accepted validly tendered Old Notes when, as and if we have given oral or written notice of our acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purpose of receiving the Exchange Notes from us.

        If any tendered Old Notes are not accepted for exchange because of an invalid tender or the occurrence of specified other events set forth in this prospectus, the certificates for any unaccepted Old Notes will be promptly returned, without expense, to the tendering holder.

        Holders who tender Old Notes in the exchange offer will not be required to pay brokerage commissions or fees or transfer taxes with respect to the exchange of Old Notes pursuant to the exchange offer. We will pay all charges and expenses, other than transfer taxes in certain circumstances, in connection with the exchange offer. See "Fees and expenses" and "Transfer taxes" below.

        The exchange offer will remain open for at least 20 full business days. The term "expiration date" will mean 5:00 p.m., New York City time, on                        , 2011, unless we, in our sole discretion, extend the exchange offer, in which case the term "expiration date" will mean the latest date and time to which the exchange offer is extended.

Table of Contents

        To extend the exchange offer, prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date, we will:

        (1)   notify the exchange agent of any extension by oral notice (promptly confirmed in writing) or written notice, and

        (2)   mail to the registered holders an announcement of any extension, and issue a notice by press release or other public announcement before such expiration date.

We reserve the right, in our sole discretion:

        (1)   if any of the conditions below under the heading "—Conditions on the Exchange Offer" shall have not been satisfied,

        (a)   to delay accepting any Old Notes,

        (b)   to extend the exchange offer, or

        (c)   to terminate the exchange offer, or

        (2)   to amend the terms of the exchange offer in any manner, provided however, that if we amend the exchange offer to make a material change, including the waiver of a material condition, we will extend the exchange offer, if necessary, to keep the exchange offer open for at least five business days after such amendment or waiver; provided further, that if we amend the exchange offer to change the percentage of Old Notes being exchanged or the consideration being offered, we will extend the exchange offer, if necessary, to keep the exchange offer open for at least ten business days after such amendment or waiver.

Any delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice to the registered holders.

Procedures for Tendering Old Notes Through Brokers and Banks

        Since the Old Notes are represented by global book-entry notes, DTC, as depositary, or its nominee is treated as the registered holder of the Old Notes and will be the only entity that can tender your Old Notes for Exchange Notes. Therefore, to tender Old Notes subject to this exchange offer and to obtain Exchange Notes, you must instruct the institution where you keep your Old Notes to tender your Old Notes on your behalf so that they are received on or prior to the expiration of this exchange offer.

        The letter of transmittal that may accompany this prospectus may be used by you to give such instructions.

        YOU SHOULD CONSULT YOUR ACCOUNT REPRESENTATIVE AT THE BROKER OR BANK WHERE YOU KEEP YOUR OLD NOTES TO DETERMINE THE PREFERRED PROCEDURE.

        IF YOU WISH TO ACCEPT THIS EXCHANGE OFFER, PLEASE INSTRUCT YOUR BROKER OR ACCOUNT REPRESENTATIVE IN TIME FOR YOUR OLD NOTES TO BE TENDERED BEFORE THE 5:00 PM (NEW YORK CITY TIME) DEADLINE ON                        , 2011.

Deemed Representations

        To participate in the exchange offer, we require that you represent to us that:

        (1)   you or any other person acquiring Exchange Notes in exchange for your Old Notes in the exchange offer is acquiring them in the ordinary course of business;

        (2)   neither you nor any other person acquiring Exchange Notes in exchange for your Old Notes in the exchange offer is engaging in or intends to engage in a distribution of the Exchange Notes within the meaning of the federal securities laws;

Table of Contents

        (3)   neither you nor any other person acquiring Exchange Notes in exchange for your Old Notes has an arrangement or understanding with any person to participate in the distribution of Exchange Notes issued in the exchange offer;

        (4)   neither you nor any other person acquiring Exchange Notes in exchange for your Old Notes is our "affiliate" as defined under Rule 405 of the Securities Act; and

        (5)   if you or another person acquiring Exchange Notes in exchange for your Old Notes is a broker-dealer and you acquired the Old Notes as a result of market-making activities or other trading activities, you acknowledge that you will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of the Exchange Notes.

BY TENDERING YOUR OLD NOTES YOU ARE DEEMED TO HAVE MADE THESE REPRESENTATIONS.

        Broker-dealers who cannot make the representations in item (5) of the paragraph above cannot use this exchange offer prospectus in connection with resales of the Exchange Notes issued in the exchange offer.

        If you are our "affiliate," as defined under Rule 405 of the Securities Act, if you are a broker-dealer who acquired your Old Notes in the initial offering and not as a result of market-making or trading activities, or if you are engaged in or intend to engage in or have an arrangement or understanding with any person to participate in a distribution of Exchange Notes acquired in the exchange offer, you or that person:

        (1)   may not rely on the applicable interpretations of the Staff of the SEC and therefore may not participate in the exchange offer; and

        (2)   must comply with the registration and prospectus delivery requirements of the Securities Act or an exemption therefrom when reselling the Old Notes.

You may tender some or all of your Old Notes in this exchange offer. However, your Old Notes may be tendered only in integral multiples of $1,000.

        When you tender your outstanding Old Notes and we accept them, the tender will be a binding agreement between you and us as described in this prospectus.

        The method of delivery of outstanding Old Notes and all other required documents to the exchange agent is at your election and risk.

        We will decide all questions about the validity, form, eligibility, acceptance and withdrawal of tendered Old Notes, and our reasonable determination will be final and binding on you. We reserve the absolute right to:

        (1)   reject any and all tenders of any particular Old Note not properly tendered;

        (2)   refuse to accept any Old Note if, in our reasonable judgment or the judgment of our counsel, the acceptance would be unlawful; and

        (3)   waive any defects or irregularities or conditions of the exchange offer as to any particular Old Notes before the expiration of the offer.

Our interpretation of the terms and conditions of the exchange offer will be final and binding on all parties. You must cure any defects or irregularities in connection with tenders of Old Notes as we will reasonably determine. Neither we, the exchange agent nor any other person will incur any liability for failure to notify you or any defect or irregularity with respect to your tender of Old Notes. If we waive any terms or conditions pursuant to (3) above with respect to a noteholder, we will extend the same waiver to all noteholders with respect to that term or condition being waived.

Procedures for Brokers and Custodian Banks; DTC ATOP Account

        In order to accept this exchange offer on behalf of a holder of Old Notes you must submit or cause your DTC participant to submit an Agent's Message as described below.

        The exchange agent, on our behalf will seek to establish an Automated Tender Offer Program ("ATOP") account with respect to the outstanding Old Notes at DTC promptly after the delivery of this prospectus. Any financial institution that is a DTC participant, including your broker or bank, may make book-entry tender of outstanding Old Notes by causing the book-entry transfer of such Old Notes into our ATOP account in accordance with DTC's procedures for such transfers. Concurrently with the delivery of Old Notes, an Agent's Message in connection with such book-entry transfer must be transmitted by DTC to, and received by, the exchange agent on or prior to 5:00 pm, New York City Time on the expiration date. The confirmation of a book entry transfer into the ATOP account as described above is referred to herein as a "Book-Entry Confirmation."

        The term "Agent's Message" means a message transmitted by the DTC participants to DTC, and thereafter transmitted by DTC to the exchange agent, forming a part of the Book-Entry Confirmation which states that DTC has received an express acknowledgment from the participant in DTC described in such Agent's Message stating that such participant and beneficial holder agree to be bound by the terms of this exchange offer.

        Each Agent's Message must include the following information:

        (1)   Name of the beneficial owner tendering such Old Notes;

        (2)   Account number of the beneficial owner tendering such Old Notes;

        (3)   Principal amount of Old Notes tendered by such beneficial owner; and

        (4)   A confirmation that the beneficial holder of the Old Notes tendered has made the representations for our benefit set forth under "—Deemed Representations" above.

        BY SENDING AN AGENT'S MESSAGE THE DTC PARTICIPANT IS DEEMED TO HAVE CERTIFIED THAT THE BENEFICIAL HOLDER FOR WHOM NOTES ARE BEING TENDERED HAS BEEN PROVIDED WITH A COPY OF THIS PROSPECTUS.

        The delivery of Old Notes through DTC, and any transmission of an Agent's Message through ATOP, is at the election and risk of the person tendering Old Notes. We will ask the exchange agent to instruct DTC to promptly return those Old Notes, if any, that were tendered through ATOP but were not accepted by us, to the DTC participant that tendered such Old Notes on behalf of holders of the Old Notes.

Acceptance of Outstanding Old Notes for Exchange; Delivery of Exchange Notes

        We will accept validly tendered Old Notes when the conditions to the exchange offer have been satisfied or we have waived them. We will have accepted your validly tendered Old Notes when we have given oral or written notice to the exchange agent. The exchange agent will act as agent for the tendering holders for the purpose of receiving the Exchange Notes from us. If we do not accept any tendered Old Notes for exchange by book-entry transfer because of an invalid tender or other valid reason, we will credit the Notes to an account maintained with DTC promptly after the exchange offer terminates or expires.

        THE AGENT'S MESSAGE MUST BE TRANSMITTED TO EXCHANGE AGENT ON OR BEFORE 5:00 PM, NEW YORK CITY TIME, ON THE EXPIRATION DATE.

Withdrawal Rights

        You may withdraw your tender of outstanding notes at any time before 5:00 p.m., New York City time, on the expiration date.

        For a withdrawal to be effective, you should contact your bank or broker where your Old Notes are held and have them send an ATOP notice of withdrawal so that it is received by the exchange agent before 5:00 p.m., New York City time, on the expiration date. Such notice of withdrawal must:

        (1)   specify the name of the person that tendered the Old Notes to be withdrawn;

        (2)   identify the Old Notes to be withdrawn, including the CUSIP number and principal amount at maturity of the Old Notes; specify the name and number of an account at the DTC to which your withdrawn Old Notes can be credited.

We will decide all questions as to the validity, form and eligibility of the notices and our determination will be final and binding on all parties. Any tendered Old Notes that you withdraw will not be considered to have been validly tendered. We will promptly return any outstanding Old Notes that have been tendered but not exchanged, or credit them to the DTC account. You may re-tender properly withdrawn Old Notes by following one of the procedures described above before the expiration date.

Conditions on the Exchange Offer

        Notwithstanding any other provision of the exchange offer, or any extension of the exchange offer, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any outstanding Old Notes and may terminate the exchange offer (whether or not any Old Notes have been accepted for exchange) or amend the exchange offer, if any of the following conditions has occurred or exists or has not been satisfied, or has not been waived by us in our sole reasonable discretion, prior to the expiration date:

•

there is threatened, instituted or pending any action or proceeding before, or any injunction, order or decree issued by, any court or governmental agency or other governmental regulatory or administrative agency or commission:

        (1)   seeking to restrain or prohibit the making or completion of the exchange offer or any other transaction contemplated by the exchange offer, or assessing or seeking any damages as a result of this transaction; or

        (2)   resulting in a material delay in our ability to accept for exchange or exchange some or all of the Old Notes in the exchange offer; or

        (3)   any statute, rule, regulation, order or injunction has been sought, proposed, introduced, enacted, promulgated or deemed applicable to the exchange offer or any of the transactions contemplated by the exchange offer by any governmental authority, domestic or foreign; or

•

any action has been taken, proposed or threatened, by any governmental authority, domestic or foreign, that, in our sole reasonable judgment, would directly or indirectly result in any of the consequences referred to in clauses (1), (2) or (3) above or, in our sole reasonable judgment, would result in the holders of Exchange Notes having obligations with respect to resales and transfers of Exchange Notes which are greater than those described in the interpretation of the SEC referred to above, or would otherwise make it inadvisable to proceed with the exchange offer; or the following has occurred:

        (1)   any general suspension of or general limitation on prices for, or trading in, securities on any national securities exchange or in the over-the-counter market; or

        (2)   any limitation by a governmental authority which adversely affects our ability to complete the transactions contemplated by the exchange offer; or

there shall occur a change in the current interpretation by the Staff of the SEC which permits the Exchange Notes issued pursuant to the exchange offer in exchange for Old Notes to be offered for resale, resold and otherwise transferred by holders thereof (other than broker-dealers and any such holder which is our affiliate within the meaning of Rule 405 promulgated under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Exchange Notes are acquired in the ordinary course of such holders' business and such holders have no arrangement or understanding with any person to participate in the distribution of such Exchange Notes; or

any law, statute, rule or regulation shall have been adopted or enacted which, in our reasonable judgment, would impair our ability to proceed with the exchange offer; or



•

a stop order shall have been issued by the SEC or any state securities authority suspending the effectiveness of the registration statement, or proceedings shall have been initiated or, to our knowledge, threatened for that purpose, or any governmental approval has not been obtained, which approval we shall, in our sole reasonable discretion, deem necessary for the consummation of the exchange offer as contemplated hereby; or



•

we have received an opinion of counsel experienced in such matters to the effect that there exists any actual or threatened legal impediment (including a default or prospective default under an agreement, indenture or other instrument or obligation to which we are a party or by which we are bound) to the consummation of the transactions contemplated by the exchange offer.

If we determine in our sole reasonable discretion that any of the foregoing events or conditions has occurred or exists or has not been satisfied, we may, subject to applicable law, terminate the exchange offer (whether or not any Old Notes have been accepted for exchange) or may waive any such condition or otherwise amend the terms of the exchange offer in any respect. If such waiver or amendment constitutes a material change to the exchange offer, we will promptly disclose such waiver or amendment by means of a prospectus supplement that will be distributed to the registered holders of the Old Notes and will extend the exchange offer to the extent required by Rule 14e-1 promulgated under the Exchange Act.

        These conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to any of these conditions, or we may waive them, in whole or in part, in our sole reasonable discretion, provided that we will not waive any condition with respect to an individual holder of Old Notes unless we waive that condition for all such holders. Any reasonable determination made by us concerning an event, development or circumstance described or referred to above will be final and binding on all parties. Our failure at any time to exercise any of the foregoing rights will not be a waiver of our rights and each such right will be deemed an ongoing right which may be asserted at any time before the expiration of the exchange offer.

Exchange Agent

        Wilmington Trust FSB has been appointed as Exchange Agent in connection with the Exchange Offer. Questions and requests for assistance, as well as requests for additional copies of this prospectus or of the letter of transmittal, should be directed to the Exchange Agent at its offices at Wilmington Trust FSB, c/o Wilmington Trust Company, Corporate Capital Markets, Rodney Square North, 1100 North Market Street, Wilmington, Delaware 19890-1626. The Exchange Agent's telephone number is (302) 636-6181 and facsimile number is (302) 636-4139.

Fees and Expenses

        The principal solicitation is being made through DTC by Wilmington Trust FSB, as exchange agent. We will pay the exchange agent customary fees for its services, reimburse the exchange agent for its reasonable out-of-pocket expenses incurred in connection with the provisions of these services and pay other registration expenses, including registration and filing fees, fees and expenses of compliance with federal securities and state blue sky securities laws, printing expenses, messenger and delivery services and telephone, fees and disbursements to our counsel, application and filing fees and any fees and disbursements to our independent certified public accountants. We will not make any payment to brokers, dealers, or others soliciting acceptances of the exchange offer except for reimbursement of mailing expenses.

        Additional solicitations may be made by telephone, facsimile or in person by our and our affiliates' officers, employees and by persons so engaged by the exchange agent.

Accounting Treatment

        The Exchange Notes will be recorded at the same carrying value as the existing Old Notes, as reflected in our accounting records on the date of exchange. Accordingly, we will recognize no gain or loss for accounting purposes. The expenses of the exchange offer will be capitalized and expensed over the term of the Exchange Notes.

Transfer Taxes

        If you tender outstanding Old Notes for exchange you will not be obligated to pay any transfer taxes. However, if you instruct us to register Exchange Notes in the name of, or request that your Old Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder, you will be responsible for paying any transfer tax owed.

        YOU MAY SUFFER ADVERSE CONSEQUENCES IF YOU FAIL TO EXCHANGE OUTSTANDING OLD NOTES.

        If you do not tender your outstanding Old Notes, you will not have any further registration rights, except for the rights described in the Registration Rights Agreement and described above, and your Old Notes will continue to be subject to the provisions of the indenture governing the Old Notes regarding transfer and exchange of the Old Notes and the restrictions on transfer of the Old Notes imposed by the Securities Act and state securities laws when we complete the exchange offer. These transfer restrictions are required because the Old Notes were issued under an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. Accordingly, if you do not tender your Old Notes in the exchange offer, your ability to sell your Old Notes could be adversely affected. Once we have completed the exchange offer, holders who have not tendered notes will not continue to be entitled to any increase in interest rate that the indenture governing the Old Notes provides for if we do not complete the exchange offer.

Consequences of Failure to Exchange

        The Old Notes that are not exchanged for Exchange Notes pursuant to the exchange offer will remain restricted securities. Accordingly, the Old Notes may be resold only:

        (1)   to us upon redemption thereof or otherwise;

        (2)   so long as the outstanding securities are eligible for resale pursuant to Rule 144A, to a person inside the United States who is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act in a transaction meeting the requirements of Rule 144A, in accordance with Rule 144 under the Securities Act, or pursuant to another exemption from the registration requirements of the Securities Act, which other exemption is based upon an opinion of counsel reasonably acceptable to us;

        (3)   outside the United States to a foreign person in a transaction meeting the requirements of Rule 904 under the Securities Act; or

        (4)   pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any state of the United States.

Shelf Registration

        The Registration Rights Agreement also requires that we file a shelf registration statement if:

        (1)   we cannot file a registration statement for the exchange offer because the exchange offer is not permitted by law or SEC policy;

        (2)   a law or SEC policy prohibits a holder from participating in the exchange offer;

        (3)   a holder cannot resell the Exchange Notes it acquires in the exchange offer without delivering a prospectus and this prospectus is not appropriate or available for resales by the holder; or

        (4)   a holder is a broker-dealer and holds notes acquired directly from us or one of our affiliates.

        We will also register the Exchange Notes under the securities laws of jurisdictions that holders may request before offering or selling notes in a public offering. We do not intend to register Exchange Notes in any jurisdiction unless a holder requests that we do so.

        Old Notes may be subject to restrictions on transfer until:

        (1)   a person other than a broker-dealer has exchanged the Old Notes in the exchange offer;

        (2)   a broker-dealer has exchanged the Old Notes in the exchange offer and sells them to a purchaser that receives a prospectus from the broker-dealer on or before the sale;

        (3)   the Old Notes are sold under an effective shelf registration statement that we have filed; or

        (4)   the Old Notes are sold to the public under Rule 144 of the Securities Act.

DESCRIPTION OF EXCHANGE NOTES

General

        In this description, references to the "Notes" are to the exchange notes, unless the context otherwise requires. We issued the old notes and will issue the exchange notes pursuant to an indenture dated as of October 20, 2010 (the "Indenture"), among Tutor Perini, as the Issuer, certain subsidiaries of Tutor Perini as guarantors and Wilmington Trust FSB, as trustee (the "Trustee"). 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 the Indenture in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the Notes. Copies of the Indenture are available upon written request to the Issuer as described below under "Incorporation of Certain Information by Reference." Definitions of certain terms are set forth under "—Certain Definitions."

        Principal of the Notes will be payable, and the Notes may be exchanged or transferred, at the office or agency of the Issuer, which, unless otherwise provided by the Issuer, will be the offices of the Trustee. Payment of interest will be made by check mailed to the addresses of the noteholders as such addresses appear in the Note register or, at the election of any noteholder in the manner prescribed by the Indenture, by wire transfer of immediately available funds.

        The Notes will be issued only in fully registered form, without coupons, in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

Terms of the Notes

        We are offering $300.0 million aggregate principal amount of the Notes, which will mature on November 1, 2018. Subject to compliance with the covenant described under "—Certain Covenants—Limitation on Incurrence of Indebtedness," we can issue additional Notes from time to time in the future as part of the same series without consent from holders of the Notes. Any additional Notes that we issue in the future will be identical in all respects to the Notes offered hereby and will be treated as a single class for all purposes of the Indenture, except that Notes issued in the future may have different issuance prices and will have different issuance dates.

        The Notes will bear interest at the rate per annum shown on the cover page of this prospectus from the Issue Date, or from the most recent date to which interest has been paid or provided for, payable semi-annually on May 1 and November 1 of each year, commencing May 1, 2011, to holders of record at the close of business on the immediately preceding April 15 and October 15, respectively. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Ranking

        The Notes and the Guarantees will rank equally with existing and future unsubordinated obligations of Tutor Perini and the Guarantors, respectively. The Notes and the Guarantees will be structurally subordinated to the obligations of any Subsidiary of the Issuer that is not a Guarantor. If the Issuer or a Guarantor incurs any Indebtedness in the future that provides by its terms that it is subordinated to the Notes or the Guarantee of such Guarantor, as the case may be, the Notes or that Guarantee, as applicable, will rank senior to that Indebtedness.

        The Notes and the Guarantees will be effectively subordinated to all secured indebtedness of the Issuer and each of the Guarantors to the extent of the assets securing such indebtedness.

Table of Contents

Optional Redemption

        At any time prior to November 1, 2014, the Issuer may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days' prior notice mailed by first-class mail to the registered address of each holder of Notes or otherwise delivered in accordance with the procedures of DTC, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to the date of redemption (the "Redemption Date"), subject to the rights of the holders of record on the relevant record date to receive interest due on the relevant interest payment date.

        The Notes will be redeemable at the option of the Issuer, in whole or in part, at any time on or after November 1, 2014 at the redemption prices (expressed as a percentage of principal amount) set forth below, plus 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 twelve month period beginning on November 1 of the years indicated below:

        Notwithstanding the foregoing, at any time on or prior to November 1, 2013 the Issuer may, at its option on any one or more occasions, redeem Notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of 107.625% of the principal amount, plus accrued and unpaid interest to the redemption date, with an amount equal to the Net Cash Proceeds of one or more Equity Offerings; 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 (excluding Notes held by the Issuer and its Subsidiaries); and

        (2)   the redemption occurs within 90 days of the date of the closing of such Equity Offering.

Selection and Notice

        If less than all the Notes issued under the Indenture are to be redeemed at any time, selection of Notes for redemption will be made by the Trustee on a pro rata basis, by lot or by such method as may be required pursuant to the applicable procedures of DTC; provided that no Notes of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of Notes to be redeemed at its registered address. Notices of redemption may not be conditional. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

Guarantees

        The Issuer and each of the Subsidiaries of Tutor Perini that guarantees the obligations of Tutor Perini or any Domestic Subsidiary (other than an Unrestricted Subsidiary) under any of the Credit Facilities will deliver a Guarantee on the date that is the later of (x) the Issue Date and (y) the date on which such Subsidiary guarantees the obligations of Tutor Perini or any Domestic Subsidiary (other

29

---

Table of Contents

than an Unrestricted Subsidiary) under any of the Credit Facilities. Pursuant to the Guarantees, each of the Guarantors will fully and unconditionally guarantee all Obligations of the Issuer under the Indenture and the Notes on a senior basis. Newly formed or acquired Subsidiaries that guarantee the obligations of Tutor Perini or any Domestic Subsidiary (other than an Unrestricted Subsidiary) under any of the Credit Facilities are required to become Guarantors, as described under "—Additional Guarantees."

        Each Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by the applicable Guarantor without rendering such Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each Guarantor that makes a payment or distribution under a Guarantee will be entitled to a contribution from each other Guarantor in an amount pro rata, based on the net assets of each Guarantor. See "Risk Factors—Risks Relating to the Notes—Federal and state laws allow courts, under certain circumstances, to void guarantees and require note holders to return payments received from guarantors."

        The Guarantee of any Restricted Subsidiary will be automatically and unconditionally released and discharged upon any of the following:

•

any sale, exchange or transfer by the Issuer or any Restricted Subsidiary to any Person or Persons, as a result of which the Restricted Subsidiary is no longer a Subsidiary of the Issuer, of a majority of the Capital Stock of, or all or substantially all the assets of, such Restricted Subsidiary, which sale, exchange or transfer is made in accordance with the provisions of the Indenture;



•

the designation of such Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the provisions of the Indenture; or



•

the release or discharge of the guarantee by such Guarantor under the Credit Facilities;

provided, in each such case, that the Issuer has delivered to the Trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent provided for in the Indenture relating to such transactions have been complied with and that such release is authorized and permitted under the Indenture.

Change of Control

        If a Change of Control occurs, each noteholder will have the right to require the Issuer to purchase all or a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such holder's Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date fixed for redemption), in accordance with the provisions of the next paragraph.

        Within 30 days following any Change of Control, the Issuer shall mail a notice to each noteholder, with a copy to the Trustee, stating

•

that a Change of Control has occurred and that such noteholder has the right to require the Issuer to purchase such holder's Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest on an interest payment date that is on or prior to the date fixed for purchase);

30

---

Table of Contents

•

the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and



•

the instructions as determined by the Issuer, consistent with the covenant described hereunder, that a noteholder must follow in order to have its Notes purchased.

        The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the purchase of Notes pursuant to the Indenture. To the extent that the provisions of any securities laws or regulations conflict with the 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 any covenant of the Indenture by virtue of this compliance.

        The Change of Control provision will not require us to make a Change of Control Offer upon the consummation of any transaction contemplated by clauses (1) and (3) of the definition of Change of Control if the party that will own, directly or indirectly, more than 50% of the Voting Stock of the Company as a result of such transaction is a Permitted Holder. See "—Certain Definitions—Permitted Holders." As a result of the definition of Permitted Holders, a concentration of control in the hands of Permitted Holders would not give rise to a situation where holders could have their Notes repurchased pursuant to a Change of Control Offer.

        The occurrence of a Change of Control would constitute a default under the Credit Facilities. In addition, the Issuer's ability to purchase the Notes for cash may be limited by the Issuer's then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any purchases required in connection with a Change of Control. The Issuer's failure to purchase the Notes in connection with a Change of Control would result in a default under the Indenture, which would, in turn, constitute a default under the Credit Facilities.

        The definition of Change of Control includes a phrase relating to the sale, assignment, transfer, lease, conveyance or other disposition of "all or substantially all" of the properties or assets of Tutor Perini and certain of its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a noteholder to require us to repurchase its Notes as a result of a sale, assignment, transfer, lease, conveyance or other disposition of less than all of the assets of Tutor Perini and certain subsidiaries taken as a whole to another person or group may be uncertain.

Certain Covenants

        The Indenture will contain certain covenants, including, among others, the following:

Limitation on Incurrence of Indebtedness

        The Issuer will not, and will not permit any Restricted Subsidiary to, incur, directly or indirectly, any Indebtedness; provided that the Issuer or any Guarantor may incur Indebtedness if, immediately after giving effect to such incurrence, the Consolidated Coverage Ratio is at least 2.0 to 1.0 determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, and the application of proceeds therefrom, had occurred at the beginning of such four-quarter period (this proviso, the "Coverage Ratio Exception").

        The foregoing paragraph will not prohibit incurrence of the following Indebtedness (collectively, "Permitted Indebtedness"):

        (1)   the Notes issued on the Issue Date and any related Guarantees;

31

        (4)   Refinancing Indebtedness in respect of Indebtedness incurred pursuant to the Coverage Ratio Exception, clause (1) of this paragraph, clause (2) of this paragraph (other than any Indebtedness owed to the Issuer or any of its Subsidiaries), this clause (4), clause (13) or clause (20);

        (5)   Indebtedness owed by the Issuer or any Restricted Subsidiary to the Issuer or a Restricted Subsidiary; provided that

•

any such Indebtedness owed by the Issuer shall be subordinated by its terms to the prior payment in full in cash of all Obligations with respect to the Notes, and any such Indebtedness owed by any Guarantor (other than to the Issuer or any other Guarantor) shall be subordinated by its terms to the prior payment in full in cash of all Obligations with respect to the Guarantee of such Guarantor; and



•

if such Indebtedness is held by a Person other than the Issuer or a Restricted Subsidiary, the Issuer or such Restricted Subsidiary shall be deemed to have incurred Indebtedness not permitted by this clause (5);

        (6)   (x) the guarantee by the Issuer or any Guarantor of Indebtedness of the Issuer or a Guarantor and (y) the guarantee by any Restricted Subsidiary that is not a Guarantor of Indebtedness of any other Restricted Subsidiary that is not a Guarantor; provided that, in each case, the Indebtedness being guaranteed is incurred pursuant to the Coverage Ratio Exception or is Permitted Indebtedness;

        (7)   Hedging Obligations;

        (8)   Purchase Money Indebtedness and Capital Lease Obligations of the Issuer or any Restricted Subsidiary incurred to finance the acquisition, construction or improvement of any assets (including capital expenditures of the Issuer or any Restricted Subsidiary), and Refinancings thereof, in an aggregate amount at any time outstanding pursuant to this clause (8) not to exceed the greater of $125.0 million and 15% of Consolidated Net Tangible Assets;

        (9)   Indebtedness of any Foreign Subsidiary in an aggregate amount not to exceed at any time outstanding pursuant to this clause (9) not to exceed $75.0 million;

        (10) Indebtedness of the Issuer or any of its Restricted Subsidiaries represented by worker's compensation claims and other statutory or regulatory obligations, self-insurance obligations, tender, bid, performance, government contract, surety or appeal bonds, standby letters of credit and warranty and contractual service obligations of like nature, trade letters of credit or documentary letters of credit, in each case to the extent incurred in the ordinary course of business of the Issuer or such Restricted Subsidiary;

        (11) customary indemnification, adjustment of purchase price or similar obligations, in each case, incurred in connection with the acquisition or disposition of any assets of the Issuer or any

Restricted Subsidiary (other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such assets for the purpose of financing such acquisition);

        (12) obligations in respect of performance bonds and completion, guarantee, surety and similar bonds in the ordinary course of business;

        (13) Acquired Indebtedness; provided that after giving effect to such acquisition or merger, either

•

the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or



•

the Consolidated Coverage Ratio of the Issuer and the Restricted Subsidiaries is equal to or greater than immediately prior to such acquisition or merger;

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

        (15) Indebtedness consisting of Guarantees incurred in the ordinary course of business under repurchase agreements or similar agreements in connection with the financing of sales of goods in the ordinary course of business;

        (16) Indebtedness under surety bonds obtained in connection with the Construction Business;

        (17) Indebtedness owing by the Issuer to CIS consisting of all or any portion of the proceeds of any payments made by the Issuer or Permitted Insureds to CIS as premiums for the insurance policies issued by CIS to the Issuer or such Permitted Insureds, respectively;

        (18) additional Indebtedness in an aggregate principal amount not to exceed $75.0 million at any time outstanding pursuant to this clause (18);

        (19) Indebtedness incurred to finance insurance premiums not to exceed $25.0 million aggregate outstanding at any time;

        (20) Contribution Indebtedness;

        (21) Indebtedness from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within 10 business days of its incurrence; and

        (22) the incurrence of Indebtedness by Unrestricted Subsidiaries.

        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 (22) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of Indebtedness described and may later reclassify such item into any one or more of the categories of Indebtedness described above and such Indebtedness will be deemed to be incurred under the category into which it was last reclassified (provided that at the time of reclassification it meets the criteria in such category or categories; provided further that Indebtedness under clause (i) of the definition of "Credit Facilities" outstanding on the Issue Date will be deemed to have been incurred in reliance on clause (3) above). The maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary may incur pursuant to this covenant will not be deemed to be exceeded solely as the result of fluctuations in the exchange rates of currencies. In determining the amount of Indebtedness incurred or outstanding, the principal amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such Person or any other Person arising under any guarantee, Lien, letter of credit or similar

33

instrument supporting such Indebtedness shall be disregarded so long as such other Person could have incurred such obligation hereunder.

        Accrual of interest or dividends, the accretion of accreted value, the accretion or amortization of original issue discount and the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as the case may be, of the same class will not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock.

        For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant to and in compliance with, this section any other obligation of the obligor on such Indebtedness (or of any other Person who could have incurred such Indebtedness under this section) arising under any Guarantee, Lien or letter of credit, bankers' acceptance or other similar instrument or obligation supporting such Indebtedness shall be disregarded to the extent that such Guarantee, Lien or letter of credit, bankers' acceptance or other similar instrument or obligation secures the principal amount of such Indebtedness.

        Notwithstanding the foregoing, the Issuer will not, and will not permit any other Guarantor to, incur any Indebtedness that purports to be by its terms (or by the terms of any agreement or instrument governing such Indebtedness) subordinated in right of payment to any other Indebtedness of the Issuer or of such other Guarantor, as the case may be, unless such Indebtedness is also by its terms made subordinated in right of payment to the Notes or the Guarantee of such Guarantor, as applicable, to at least the same extent as such Indebtedness is subordinated in right of payment to such other Indebtedness of the Issuer or such Guarantor, as the case may be.

Limitation on Restricted Payments

        The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, declare or make a Restricted Payment if:

        (1)   a Default has occurred and is continuing or would result therefrom;

        (2)   the Issuer could not incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

        (3)   the aggregate amount of such Restricted Payment, together with all other Restricted Payments (the amount of any Restricted Payments made in assets other than cash to be valued at its Fair Market Value) declared or made since the Issue Date (other than any Restricted Payment described in clauses (2) through (10) of the next paragraph), would exceed the sum (the "Basket") of

        (a)   50% of the Consolidated Net Income accrued during the period (treated as one accounting period) from July 1, 2010 to the end of the most recent fiscal quarter prior to the date of such Restricted Payment for which internal financial statements are available (or, in case such Consolidated Net Income shall be a deficit, minus 100% of such deficit); plus

        (b)   the aggregate Net Cash Proceeds from capital contributions or the issuance and sale (other than to a Subsidiary of the Issuer) of, and the Fair Market Value of any property received in exchange for, Qualified Stock, or as a capital contribution, received by the Issuer subsequent to the Issue Date (other than Contribution Amounts, Excluded Contributions, and amounts received in exchange for the issuance of Designated Preferred Stock) or from the issue or sale of debt securities of the Issuer that have been converted or exchanged into Qualified Stock, together with the aggregate cash and Temporary Cash Investments received by the Issuer or any of its Restricted Subsidiaries at the time of such conversion or exchange; provided that for purposes of determining the Fair Market Value of property received (other than of any asset with a public trading market) in excess of $25.0 million shall be determined

by an Independent Financial Advisor, which determination shall be evidenced by an opinion addressed to the Issuer and delivered to the Trustee; plus

        (c)   the amount by which Indebtedness or Disqualified Stock incurred or issued subsequent to the Issue Date is reduced on the Issuer's consolidated balance sheet upon the conversion or exchange (other than by a Subsidiary of the Issuer) into Qualified Stock (less the amount of any cash, or the Fair Market Value of any other asset, distributed by the Issuer or any Restricted Subsidiary upon such conversion or exchange); provided that such amount shall not exceed the aggregate Net Cash Proceeds received by the Issuer or any Restricted Subsidiary after the Issue Date from the issuance and sale (other than to a Subsidiary of the Issuer) of such Indebtedness or Disqualified Stock; plus

        (d)   to the extent not included in the calculation of the Consolidated Net Income referred to in (a), an amount equal to, without duplication:

•

Limitation on Transactions with Affiliates

        The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or series of related transactions, Transfer 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 of the Issuer (an "Affiliate Transaction"), unless the terms thereof, taken as a whole, are no less favorable to the Issuer or such Restricted Subsidiary than those that could be obtained at the time of such transaction in arm's-length dealings with a Person that is not such an affiliate.

        The Board of Directors must approve each Affiliate Transaction that involves aggregate payments or other assets or services with a Fair Market Value in excess of $20.0 million. This approval must be evidenced by a board resolution that states that such board has determined that the transaction complies with the foregoing provisions.

        If the Issuer or any Restricted Subsidiary enters into an Affiliate Transaction that involves aggregate payments or other assets or services with a Fair Market Value in excess of $50.0 million, then prior to the consummation of that Affiliate Transaction, the Issuer must obtain a favorable opinion from an Independent Financial Advisor that it has determined such Affiliate Transaction to be fair, from a financial point of view, to the Company, and deliver that opinion to the Trustee.

        The provisions of the three foregoing paragraphs will not prohibit the following:

        (1)   transactions exclusively between, among or solely for the benefit of (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 more than 10% of the Capital Stock in any such Restricted Subsidiary;

        (2)   customary director, officer and employee compensation (including bonuses) and other benefits (including retirement, health, stock option and other benefit plans) and indemnification arrangements, and agreements to register securities of directors, officers, employees or other affiliates, in each case approved by the Board of Directors;

        (7)   purchases and sales of raw materials or Inventory in the ordinary course of business on market terms;

        (8)   the incurrence of any Indebtedness to the extent that (i) at least 80% amount of such Indebtedness is issued to Persons that are not affiliates of the Issuer and (ii) the terms and conditions on which such affiliates purchase such Indebtedness are no less favorable, taken as a whole, to the Issuer than the terms on which Persons that are not affiliates of the Issuer purchase such Indebtedness; or

        (9)   any transactions or agreements with Affiliates in existence on the Issue Date as described in or incorporated by reference in this prospectus and performance of the obligations of the Issuer and its Restricted Subsidiaries as required or permitted by the terms of such transactions and agreements, including, without limitation, any amendments thereto entered into after the date of the Issue Date; provided, however, that the terms of any such amendment are not less favorable, in any material respect, to the Issuer than the terms of the relevant agreement in effect prior to any such amendment, as determined in good faith by the Board of Directors of the Issuer; or

        (10) transactions in which the Issuer or any Restricted Subsidiary, as the case may be, delivers to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view or meets the requirements of the first paragraph of this covenant.

Limitation on Asset Sales

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

          (i)  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

         (ii)  at least 75% of the total consideration received in such Asset Sale consists of cash, Temporary Cash Investments or assets referred to in clause (c) below, in each case, valued at the Fair Market Value thereof, or a combination of the foregoing.

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

•

the amount (without duplication) of any liability (other than Subordinated Obligations) that would be recorded on a balance sheet prepared in accordance with GAAP of the Issuer or such Restricted Subsidiary that is expressly (i) assumed by a Person other than the Issuer or a Restricted Subsidiary, or (ii) is expunged by the holder of such liability, and with respect to which, in each case, the Issuer or such Restricted Subsidiary, as the case may be, is unconditionally released from further liability with respect thereto;



•

the amount of any obligations or securities received from such Transferee that are within 180 days repaid, converted into or sold or otherwise disposed of for cash or Temporary Cash Investments (to the extent of the cash or Temporary Cash Investments actually so received); and



•

any Designated Noncash Consideration received by the Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, not to exceed the greater of (x) $75.0 million or (y) 2.5% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value.

Table of Contents

        If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary in connection with any Asset Sale is repaid, converted into or sold or otherwise disposed of for cash or Temporary Cash Investments (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion, sale or other disposition shall be deemed to constitute the date of an Asset Sale hereunder 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 a Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply an amount equal to all or any of the Net Available Proceeds therefrom as follows:

        (a)   to repay or otherwise retire amounts owing under the Credit Facilities in accordance with the Credit Facilities;

        (b)   to repay or otherwise retire amounts owing under other Indebtedness (other than Subordinated Obligations) that is secured by a Lien, which Lien is permitted by the Indenture, and to correspondingly reduce commitments with respect thereto; and/or

        (c)   to make (i) an Investment in or expenditure for assets (including Capital Stock of any Person) that replace the assets that were the subject of the Asset Sale or in assets (including Capital Stock of any Person) that will be used in the Permitted Business and (ii) capital expenditures that will be used in the Permitted Business (or, in each case of (i) and (ii), enter into a binding commitment for any such investment or expenditure); provided that such binding commitment shall be treated as a permitted application of the Net Available Proceeds from the date of such commitment until and only until the earlier of (x) the date on which such investment or expenditure is consummated and (y) the 180th day following the expiration of the aforementioned 365-day period. If the Investment or expenditure contemplated by such binding commitment is not consummated on or before the 180th day, such commitment shall be deemed not to have been a permitted application of Net Available Proceeds.

        The amount of Net Available Proceeds not applied or invested as provided in this paragraph will constitute "Excess Proceeds."

        When the aggregate amount of Excess Proceeds equals or exceeds $50.0 million, the Issuer will be required to make an offer to purchase from all noteholders an aggregate principal amount of Notes and, if the Issuer is required to do so under the terms of any other Indebtedness ranking pari passu with such Notes, such other Indebtedness on a pro rata basis with the Notes, equal to the amount of such Excess Proceeds (a "Net Proceeds Offer") in accordance with the procedures set forth in the Indenture.

        The offer price for the Notes will be payable in cash and will be 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"). If the aggregate Offered Price of Notes validly tendered and not withdrawn by noteholders thereof exceeds the amount of Excess Proceeds, Notes to be purchased will be selected on a pro rata basis. Upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds shall be reduced to zero.

        To the extent that the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer (and if applicable, the aggregate amount of pari passu Indebtedness being repaid, on a pro rata basis with the Notes) is less than the Excess Proceeds (such shortfall constituting a "Net Proceeds Deficiency"), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for general corporate purposes.

        In the event of the Transfer of substantially all (but not all) of the assets of the Issuer and the Restricted Subsidiaries as an entirety to a Person in a transaction covered by and effected in accordance with the covenant described under "—Merger, Consolidation and Sale of Assets," the Transferee 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 shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with any purchase of Notes pursuant to the Indenture. To the extent that the provisions of any securities laws or regulations conflict with the 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 Indenture by virtue of this compliance.

        (14) any restriction imposed by applicable law, rule, regulation or order.

Additional Guarantees

        The Issuer will cause any Subsidiary, whether currently existing, or subsequently acquired or created, that Guarantees the Issuer's obligations or the obligations of any Domestic Subsidiary (other than an Unrestricted Subsidiary) under any of the Credit Facilities or any other Indebtedness to fully and unconditionally guarantee all of the Issuer's obligations under the Notes and the Indenture on the terms set forth in the Indenture. Thereafter, such Subsidiary shall be a Guarantor for all purposes of the Indenture until released in accordance with the terms of the Indenture.

        The Indenture provides that upon any consolidation or merger in which the Issuer is not the continuing Person, or any Transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing, the Issuer Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the Indenture with the same effect as if the Issuer Surviving Entity had been named as such.

SEC Reports

        Whether or not the Issuer is then subject to Section 13(a) or 15(d) of the Exchange Act, the Issuer will electronically file with the Commission, so long as the Notes are outstanding, the annual reports, quarterly reports and other periodic reports that the Issuer would be required to file with the Commission pursuant to Section 13(a) or 15(d) if the Issuer were so subject, and such documents will be filed with the Commission on or prior to the respective dates (the "Required Filing Dates") by which the Issuer would be required so to file such documents if the Issuer were so subject, unless, in any case, if such filings are not then permitted by the Commission.

        If such filings with the Commission are not then permitted by the Commission, or such filings are not generally available on the Internet free of charge, the Issuer will, within 15 days of each Required Filing Date, transmit by mail to noteholders, as their names and addresses appear in the Note register, without cost to such noteholders, and file with the Trustee copies of, the annual reports, quarterly reports and other periodic reports that the Issuer would be required to file with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if the Issuer were subject to such Section 13(a) or 15(d), and, promptly upon written request, supply copies of such documents to any prospective holder or beneficial owner at the Issuer's cost.

The Issuer also will comply with the other provisions of TIA § 314(a).

Covenant Suspension

        During any period of time that (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under the Indenture (the events described in the foregoing clauses (i) and (ii) being collectively referred to as a "Covenant Suspension"), the Issuer and the Restricted Subsidiaries will not be subject to the covenants (the "Suspended Covenants") described under:

        (1)   "Limitation on Incurrence of Indebtedness";

        (2)   "Limitation on Restricted Payments";

        (3)   "Limitation on Transactions with Affiliates";

        (4)   "Limitation on Asset Sales";

        (5)   "Limitation on Dividend and Other Restrictions Affecting Restricted Subsidiaries";

        (6)   "Conduct of Business"; and

        (7)   "clause (C)(1) of "Merger, Consolidation and Asset Sales."

        In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants under the Indenture for any period of time as a result of the foregoing, and on any subsequent date (the "Reversion Date") (a) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating or (b) the Issuer or any of its affiliates enters into an agreement to effect a transaction that would result in a Change of Control and one or more of the Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings 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 under the Indenture with respect to future events. The period beginning on the day of a Covenant Suspension Event and ending on a Reversion Date is called a "Suspension Period." The ability of the Issuer and the Restricted Subsidiaries to make Restricted Payments after the time of such withdrawal, downgrade, Default or Event of Default will be calculated as if the covenant governing Restricted Payments had been in effect during the entire period of time from the Issue Date.

Events of Default

        Any of the following shall constitute an Event of Default:

        (1)   default for 30 days in the payment when due of interest on any Note;

        (2)   default in the payment when due of principal on any Note, whether upon maturity, acceleration, optional redemption, required repurchase or otherwise;

        (3)   failure to perform or comply with the covenant described under "—Change of Control";

        (4)   failure to perform or comply with any covenant, agreement or warranty in the Indenture (other than any specified in clause (1), (2) or (3) above) which failure continues for 60 days after written notice thereof has been given to the Issuer by the Trustee or to the Issuer and the Trustee by the holders of at least 25% in aggregate principal amount of then outstanding Notes;

        (5)   default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Issuer

or any Restricted Subsidiary, whether such Indebtedness now exists or is created after the Issue Date, which

•

is caused by a failure to pay such Indebtedness at Stated Maturity (after giving effect to any grace period related thereto) (a "Payment Default"); or



•

results in the acceleration of such Indebtedness prior to its Stated Maturity;

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

        If an Event of Default occurs and is continuing (other than an Event of Default described in clause (7) or (8) above with respect to the Issuer), the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default described in clause (7) or (8) above occurs with respect to the Issuer, the principal of and interest on all the Notes will immediately become due and payable without any declaration or other act on the part of the Trustee or any holders of the Notes. Under certain circumstances, the holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

        Except to enforce the right to receive payment of principal or interest when due, no noteholder may pursue any remedy with respect to the Indenture or the Notes unless:

•

such holder has previously given the Trustee notice that an Event of Default is continuing;



•

holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy;



•

such holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;



•

the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and



•

the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

        Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in personal liability.

        The Indenture will provide that if a Default occurs and is continuing and is known to the Trustee, the Trustee must mail to each noteholder notice of the Default within 90 days after it occurs. Notwithstanding the foregoing, except in the case of a Default in the payment of principal of or interest on any Note, the Trustee may withhold notice if and so long as a committee of its trust officers determines that withholding notice is in the interest of the noteholders. In addition, the Issuer is required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Issuer also is required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action the Issuer is taking or proposes to take in respect thereof.

Amendments and Waivers

        Except as provided below, the Notes and the Indenture may be amended with the consent of the holders of a majority of the aggregate principal amount of Notes then outstanding (including consents obtained in connection with a tender offer or exchange for the Notes) and any past default or

46

---

Table of Contents

compliance with any provisions may also be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding.

        Without the consent of each holder of an outstanding Note affected thereby, no amendment or waiver may:

•

reduce the principal of or change the fixed maturity of any Note;



•

alter the provisions with respect to the redemption or purchase provisions of any Note or the Indenture in a manner adverse to the holders of the Notes (other than the provisions of the Indenture relating to any offer to purchase required under the covenants described under "—Change of Control");



•

waive a redemption or purchase payment due with respect to any Note;



•

reduce the rate of or change the time for payment of interest on any Note;



•

waive a Default in the payment of principal or interest on the Notes (except that holders of at least a majority in aggregate principal amount of then outstanding Notes may (x) rescind an acceleration of the Notes that resulted from a non-payment default and (y) waive the payment default that resulted from such acceleration);



•

make the principal of or interest on any Note payable in money other than United States Dollars;



•

make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of holders of Notes to receive payments of principal of or interest on the Notes;



•

make the Notes or any Guarantee subordinated by their or its terms in right of payment to any other Indebtedness;



•

release any Guarantor that is a Significant Subsidiary from its Guarantee except in compliance with the Indenture; or



•

make any change in the amendment and waiver provisions of the Indenture.

        Without the consent of any noteholder, the Issuer and the Trustee may amend the Notes and the Indenture:

•

to cure any ambiguity, defect, mistake, or inconsistency;



•

to provide for the assumption by a successor Person of the obligations of the Issuer or any Guarantor under the Indenture in accordance with the covenant described under "—Merger, Consolidation and Sale of Assets";



•

to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);



•

to add a Guarantor;



•

to release a Guarantor from its Guarantee when permitted by the Indenture;



•

to add to the covenants of the Issuer for the benefit of the noteholders or to surrender any right or power conferred upon the Issuer;



•

to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act;

47

Table of Contents

•

to make any other change that does not materially adversely affect the rights of any noteholder; or



•

to conform the Indenture to this Description of Exchange Notes.

        The consent of the noteholders is not necessary under the Indenture to approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver.

        After an amendment or waiver under the Indenture becomes effective, the Issuer is required to mail to noteholders a notice briefly describing such amendment or waiver. However, the failure to give such notice to all noteholders, or any defect therein, will not impair or affect the validity of the amendment or waiver.

Transfer

        Notes will be issued in registered form and are transferable only upon the surrender of the Notes being transferred for registration of transfer. No service charge will be made for any registration of transfer or exchange of Notes, but the Issuer may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection therewith.

Discharge of Indenture and Defeasance

        The Indenture will, subject to certain surviving provisions, cease to be of further effect when:

        (1)   the Issuer delivers to the Trustee all outstanding Notes (other than Notes replaced because of mutilation, loss, destruction or wrongful taking) for cancellation; or

        (2)   all outstanding Notes have become due and payable, whether at maturity or as a result of the mailing of a notice of redemption as described above, and the Issuer irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Notes, including interest thereon,

and if in either case the Issuer pays all other sums payable under the Indenture by the Issuer. The Trustee will acknowledge satisfaction and discharge of the Indenture on written demand of the Issuer accompanied by an officers' certificate and an opinion of counsel and at the cost and expense of the Issuer.

        Subject to the conditions to defeasance described below and in the Indenture and the survival of certain provisions, the Issuer at any time may terminate:

        (1)   all its obligations under the Notes and the Indenture ("legal defeasance option"); or

        (2)   its obligations under certain restrictive covenants and the related Events of Default ("covenant defeasance option").

the Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuer exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default referred to in clause (2) of the immediately preceding paragraph.

        In order to exercise either defeasance option, the Issuer must irrevocably deposit in trust (the "defeasance trust") with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an opinion of counsel to the effect that holders of the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such opinion of counsel must be based on a ruling of the Internal Revenue Service or change in applicable federal income tax law).

        The holders of a majority in principal amount of the 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. The Indenture provides that if an Event of Default occurs (and is not cured), the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of such person's own affairs. Subject to such provisions and the other rights and duties of the Trustee, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any noteholder, unless such noteholder shall have offered to the Trustee security or indemnity satisfactory to it against any cost, expense and liabilities which might be incurred by it in compliance with such request.

No Personal Liability of Directors, Officers, Employees and Stockholders

        No director, officer, employee, incorporator or stockholder of the Issuer or any of its subsidiaries will have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest of such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months).

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

        The following is a summary of certain United States federal income tax considerations relating to the exchange of Old Notes for Exchange Notes in the exchange offer. It does not contain a complete analysis of all the potential tax considerations relating to the exchange. This summary is limited to holders of Old Notes who hold the Old Notes as "capital assets" (in general, assets held for investment). Special situations, such as the following, are not addressed:

•

tax consequences to holders who may be subject to special tax treatment, such as tax-exempt entities, dealers in securities or currencies, banks, other financial institutions, insurance companies, regulated investment companies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings or corporations that accumulate earnings to avoid United States federal income tax;



•

tax consequences to persons holding notes as part of a hedging, integrated, constructive sale or conversion transaction or a straddle or other risk reduction transaction;



•

tax consequences to holders whose "functional currency" is not the United States dollar;



•

tax consequences to persons who hold notes through a partnership or similar pass-through entity;



•

United States federal gift tax, estate tax or alternative minimum tax consequences, if any; or



•

any state, local or non-United States tax consequences.

        The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended, existing and proposed Treasury regulations promulgated thereunder, and rulings, judicial decisions and administrative interpretations thereunder, as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those discussed below.

Consequences of Tendering Old Notes

        The exchange of your Old Notes for Exchange Notes in the exchange offer should not constitute an exchange for United States federal income tax purposes because the Exchange Notes should not be considered to differ materially in kind or extent from the Old Notes. Accordingly, the exchange offer should have no United States federal income tax consequences to you if you exchange your Old Notes for Exchange Notes. For example, there should be no change in your tax basis and your holding period should carry over to the Exchange Notes. In addition, the United States federal income tax consequences of holding and disposing of your Exchange Notes should be the same as those applicable to your Old Notes.

        The preceding discussion of certain United States federal income tax considerations of the exchange offer is for general information only and is not tax advice. Accordingly, each investor should consult its own tax advisor as to particular tax consequences to it of exchanging Old Notes for Exchange Notes, including the applicability and effect of any state, local or foreign tax laws, and of any proposed changes in applicable laws.

PLAN OF DISTRIBUTION

        Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of Exchange Notes.

        This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes if the Old Notes were acquired as a result of market-making activities or other trading activities.

        We have agreed to make this prospectus, as amended or supplemented, available to any broker-dealer to use in connection with any such resale for a period of at least 180 days after the expiration date. In addition, until (90 days after the date of this prospectus), all broker-dealers effecting transactions in the Exchange Notes may be required to deliver a prospectus.

        We will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions:

•

in the over-the-counter market;



•

in negotiated transactions; or



•

through the writing of options on the Exchange Notes or a combination of such methods of resale.

        These resales may be made:

•

at market prices prevailing at the time of resale;



•

at prices related to such prevailing market prices; or



•

at negotiated prices.

Any such resale may be made directly to purchasers or to or through brokers or dealers. Brokers or dealers may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Notes. An "underwriter" within the meaning of the Securities Act includes:

•

any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the exchange offer; or



•

any broker or dealer that participates in a distribution of such Exchange Notes.

        Any profit on any resale of Exchange Notes and any commissions or concessions received by any persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

        For a period of not less than 180 days after the expiration of the exchange offer we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests those documents in the letter of transmittal. We have agreed to pay all expenses incident to performance of our obligations in connection with the exchange offer, other than commissions or concessions of any brokers or dealers. We will indemnify the holders of the Exchange Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act, and will contribute to payments that they may be required to make in request thereof.

Item 20.    Indemnification of Directors and Officers

Arizona

Perini Building Company, Inc. is incorporated under the laws of Arizona.

        Section 10-851 of the Arizona Revised Statutes permits a corporation to indemnify an individual made a party to a proceeding because the individual is or was a director against liability incurred in the proceeding if all of the following conditions exist: (a) the individual's conduct was in good faith; (b) the individual reasonably believed in the case of conduct in an official capacity with the corporation, that the conduct was in its best interests and in all other cases, that the conduct was at least not opposed to its best interests; and (c) in the case of any criminal proceedings, the individual had no reasonable cause to believe the conduct was unlawful. Section 10-851 of the Arizona Revised Statutes permits a corporation to indemnify an individual made a party to a proceeding because the director engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation pursuant to section 10-202, subsection B, paragraph 2 of the Arizona Revised Statutes. The termination of a proceeding by judgment, order, settlement or conviction or on a plea of no contest or its equivalent is not of itself determinative that the director did not meet the standard of conduct described in this section. Under Arizona Revised Statutes, a corporation may not indemnify a director under this section either: (a) in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation or (b) in connection with any other proceeding charging improper financial benefit to the director, whether or not involving action in the director's official capacity, in which the director was adjudged liable on the basis that financial benefit was improperly received by the director. Indemnification permitted under this section in connection with a proceeding by or in the right of the corporation is limited to reasonable expenses incurred in connection with the proceeding.

        The Articles of Incorporation of Perini Building Company, Inc. provide for the indemnification of officers and directors to the fullest extent permitted by law.

Table of Contents

damages to the corporation or any other person unless the director breached or failed to perform his or her duties as a director and the director's breach of, or failure to perform, those duties constituted:

•

a violation of the criminal law, unless the director had reasonable cause to believe his or her conduct was lawful, or had no reasonable cause to believe his or her conduct was unlawful;



•

a transaction from which the director derived an improper personal benefit, either directly or indirectly;



•

a circumstance under which the liability provisions of Florida law for unlawful distributions are applicable;



•

in a proceeding by or in the right of the corporation to procure a judgment in its favor or by or in the right of a shareholder, conscious disregard for the best interest of the corporation or willful misconduct; or



•

in a proceeding by or in the right of someone other than the corporation or by or in the right of a shareholder, recklessness or an act or omission which was committed in bad faith or with malicious purpose or in a manner exhibiting wanton and willful disregard of human rights, safety, or property.

Section 607.0850 of the FBCA empowers a Florida corporation, subject to certain limitations, to indemnify its directors, officers and employees against expenses (including attorneys' fees, judgments, fines and certain settlements) actually and reasonably incurred by them in connection with any suit or proceeding to which they are a party so long as they acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to a criminal action or proceeding, so long as they had no reasonable cause to believe their conduct to have been unlawful.

Hawaii

G.W. Murphy Construction Company, Inc. and E.E. Black, Limited are incorporated under the laws of Hawaii.

        Section 414-242 of the Hawaii Business Corporation Act provides that a corporation may indemnify an individual who is a party to a proceeding because the individual is a director against liability incurred in the proceeding if:

•

the individual conducted himself or herself in good faith and the individual reasonably believed: (i) in the case of conduct in the



•

individual's official capacity, that the individual's conduct was in the best interests of the corporation; and (ii) in all other cases, that



•

the individual's conduct was at least not opposed to the best interests of the corporation; and



•

in the case of any criminal proceeding, the individual had no reasonable cause to believe the individual's conduct was unlawful; or



•

the individual engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation.

To the extent that a director is wholly successful in the defense of any proceeding to which the director was a party because the director was a director of the corporation, the corporation is required by Section 414-243 of the Hawaii Business Corporation Act to indemnify such director for reasonable expenses incurred thereby.

        Under Section 414-244 of the Hawaii Business Corporation Act, a corporation, before final disposition of a proceeding, may advance funds to pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding because the director is a director of the corporation if the director delivers certain written affirmations and certain undertakings. Under certain circumstances, under Section 414-245 of the Hawaii Business Corporation Act, a director may apply for and obtain indemnification or an advance for expenses to the court conducting the proceeding or to another court of competent jurisdiction.

        Further, under Section 414-246 of the Hawaii Business Corporation Act, indemnification may be made only as authorized in a specific case upon a determination that indemnification is proper in the circumstances because a director has met the applicable standard, with such determination to be made:

•

by the board of directors by a majority vote of a quorum consisting of directors who were not parties to the proceeding or who do not have a familial, financial, professional or employment relationship with the director whose indemnification is the subject of the decision being made, which relationship would reasonably be expected to influence the director's judgment when voting on the decision being made;



•

by special legal counsel; or



•

by a majority vote of the shareholders.

        Under Section 414-247 of the Hawaii Business Corporation Act, a corporation may indemnify and advance expenses to an officer who is a party to a proceeding because the officer is an officer of the corporation:

•

to the same extent as a director; and



•

if the person is an officer but not a director, to such further extent as may be provided by the articles of incorporation, the bylaws, a resolution of the board of directors, or contract except for liability in connection with a proceeding by or in the right of the corporation other than for

Table of Contents

reasonable expenses incurred in connection with the proceeding, or liability arising out of conduct that constitutes: (i) receipt by the officer of a financial benefit to which the officer is not entitled; (ii) an intentional infliction of harm on the corporation or the shareholders; or (iii) an intentional violation of criminal law.

The above-described provision applies to an officer who is also a director if the basis on which officer is made a party to the proceeding is an act or omission solely as an officer. Further, an officer of a corporation who is not a director is entitled to mandatory indemnification under Section 414-243 of the Hawaii Business Corporation Act and may apply to a court under Section 414-245 of the Hawaii Business Corporation Act for indemnification or an advance for expenses, in each case to the same extent to which a director may be entitled to indemnification or advance for expenses.

        The Hawaii Business Corporation Act also provides that a corporation may include indemnification provisions in its articles of incorporation that are broader than the foregoing provisions. The restated articles of incorporation of Central Pacific, as amended, do not address the matter of indemnification of directors and officers; however, the provisions of the amended bylaws of Central Pacific relating to indemnification of directors and officers are substantially the same as the provisions of the Hawaii Business Corporation Act described above as related to the corporations obligations and authority to indemnify its directors and officers.

        The bylaws of G.W. Murphy Construction Company, Inc. provide for the indemnification of officers and directors to the fullest extent permitted by law.

        The bylaws of E.E. Black, Limited provide for the indemnification of officers and directors to the fullest extent permitted by law.

Maryland

Cherry Hill Construction, Inc. is incorporated under the laws of Maryland.

        By a Maryland statute, a Maryland corporation may indemnify any director who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative or investigative ("Proceeding") by reason of the fact that he is a present or former director of the corporation and any person who, while a director of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee, or agent of another corporation, partnership, joint venture, trust, other enterprise, or employee benefit plan ("Director"). Such indemnification may be against judgments, penalties, fines, settlements and reasonable expenses actually incurred by him in connection with the Proceeding unless it is proven that (a) the act or omission of the Director was material to the matter giving rise to the Proceeding and (i) was committed in bad faith, or (ii) was the result of active and deliberate dishonesty; or (b) the Director actually received an improper personal benefit in money, property, or services; or (c) in the case of any criminal proceeding, the Director had reasonable cause to believe his act or omission was unlawful. However, the corporation may not indemnify any Director in connection with a Proceeding by or in the right of the corporation if the Director has been adjudged to be liable to the corporation. A Director who has been successful in the defense of any Proceeding described above shall be indemnified against reasonable expenses incurred in connection with the Proceeding. The corporation may not indemnify a Director in respect of any Proceeding charging improper personal benefits to the Director in which the Director was adjudged to be liable on the basis that personal benefit was improperly received. The corporation may not indemnify a Director or advance expenses for a Proceeding brought by the Director against the corporation except if the Proceeding is brought to enforce indemnification by the corporation or if the corporation's charter or by-laws, a board resolution or contract provides otherwise. Notwithstanding the above provisions, a court of appropriate jurisdiction, upon application of the Director, may order indemnification if it determines that in view of all the relevant circumstances, the Director is fairly and reasonably entitled to indemnification;

II-6

Table of Contents

however, indemnification with respect to any Proceeding by or in the right of the corporation or in which liability was adjudged on the basis that personal benefit was improperly received shall be limited to expenses. A corporation may advance reasonable expenses to a Director under certain circumstances, including a written undertaking by or on behalf of such Director to repay the amount if it shall ultimately be determined that the standard of conduct necessary for indemnification by the corporation has not been met.

        A corporation may indemnify and advance expenses to an officer of the corporation to the same extent that it may indemnify Directors under the statute.

        The indemnification and advancement of expenses provided by statute is not exclusive of any other rights, by indemnification or otherwise, to which a Director or officer may be entitled under the charter, by-laws, a resolution of shareholders or directors, an agreement or otherwise.

        A corporation may purchase and maintain insurance on behalf of any person who is or was a Director or officer, whether or not the corporation would have the power to indemnify a Director or officer against liability under the provision of this section of Maryland law. Further, a corporation may provide similar protection, including a trust fund, letter of credit or surety bond, not inconsistent with the statute.

        The Articles of Incorporation and bylaws of Cherry Hill Construction, Inc. provide for the indemnification of officers and directors to the fullest extent permitted by law.

Massachusetts

Perini Management Services, Inc., Perini Land And Development Company, Inc. and Paramount Development Associates, Inc. are incorporated under the laws of Massachusetts.

        Section 8.51 of the Massachusetts Business Corporation Act provides that a corporation may indemnify an individual who is a party to a proceeding because he is a director against liability incurred in the proceeding if: (1)(i) he conducted himself in good faith; (ii) he reasonably believed that his conduct was in the best interests of the corporation or that his conduct was at least not opposed to the best interests of the corporation; and (iii) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful; or (2) he engaged in conduct for which he shall not be liable under a provision of the articles of organization authorized by clause (4) of subsection (b) of section 2.02. A director's conduct with respect to an employee benefit plan for a purpose he reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement that his conduct was at least not opposed to the best interests of the corporation.

        The bylaws of Perini Management Services, Inc. provide for the indemnification of officers and directors to the fullest extent permitted by law.

        The Articles of Incorporation and bylaws of Perini Land And Development Company, Inc. provide for the indemnification of officers and directors to the fullest extent permitted by law.

Table of Contents

made a party to a threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative and whether formal or informal (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise, whether for profit or not, against expenses (including attorneys' fees), judgments, penalties, fines and amounts paid in settlement actually and reasonable incurred by him or her in connection with the action, suit or proceeding, if the person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation or its shareholders, and with respect to a criminal action or proceeding, if the person had no reasonable cause to believe his or her conduct was unlawful. The termination of an action, suit or proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, does not, of itself create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation or its shareholders, and, with respect to a criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

        Indemnification of expenses (including attorneys' fees) and amounts paid in settlement is permitted in derivative actions, except that indemnification is not allowed for any claim, issue or matter in which such person has been found liable to the corporation unless and to the extent that a court decides indemnification is proper. To the extent that a director or officer has been successful in on the merits or otherwise in defense of an action, suit or proceeding, or in defense of a claim, issue or matter in the action, suit or proceeding, he or she shall be indemnified against actual and reasonable expenses (including attorneys' fees) incurred by him or her in connection with the action, suit or proceeding, and any action, suit or proceeding brought to enforce the mandatory indemnification provided under the MBCA. The MBCA permits partial indemnification for a portion of expenses (including reasonable attorneys' fees), judgments, penalties, fines and amounts paid in settlement to the extent the person is entitled to indemnification for less than the total amount.

        A determination that the person indemnified meets the applicable standard of conduct and an evaluation of the reasonableness of the expenses incurred and amounts paid in settlement shall be made by a majority vote of a quorum of the board of directors who are not parties or threatened to be made parties to the action, suit or proceeding, by a majority vote of a committee of not less than two disinterested directors, by independent legal counsel, by all "independent directors" not parties or threatened to be made parties to the action, suit or proceeding, or by the shareholders. Under the MBCA, a corporation may pay or reimburse the reasonable expenses incurred by a directors, officer, employee or agent who is a party or threatened to be made a party to an action, suit or proceeding in advance of final disposition of the proceeding if (i) the person furnishes the corporation a written affirmation of his or her good faith belief that he or she has met the applicable standard of conduct, and (ii) the person furnishes the corporation a written undertaking to repay the advance if it is ultimately determined that he or she did not meeting the standard of conduct, which undertaking need not be secured.

        The indemnification provisions of the MBCA are not exclusive of the rights to indemnification under a corporation's articles of incorporation, bylaws, or by agreement. However, the total amount of expenses advanced or indemnified from all sources combined may not exceed the amount of actual expenses incurred by the person seeking indemnification or advancement of expenses. The indemnification provided under the MBCA continues as to a person who ceases to be a director, officer, employee, or agent. Additionally, the MBCA permits a corporation to purchase insurance on behalf of its directors, officers, employees and agents against liabilities arising out of their positions with the corporation, whether or not such liabilities would be within the above indemnification provisions. An amendment to the articles of incorporation of HD Supply Fasteners & Tools, Inc.

Indemnification may include attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person to be indemnified in connection with the action, suit or proceeding. A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of being or having been an officer, director, employee or agent of the corporation or serving or having served in certain capacities at the request of the corporation except that indemnification may not be made for any claim, issue or matter as to which such a person has been finally adjudged by a court of competent jurisdiction to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that, in view of all the circumstances, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. However, to be entitled to indemnification, the person to be indemnified in either case must not be found to have breached his or her fiduciary duties with such breach involving intentional misconduct, fraud or a knowing violation of the law or must have acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, such person must have had no reasonable cause to believe his or her conduct was unlawful.

        Section 78.7502 of the NRS also provides that to the extent a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any such action, suit or proceeding he or she must be indemnified by the corporation against expenses, including attorneys' fees actually and reasonably incurred in connection with the defense.

        Section 78.751 of the NRS permits a corporation, in its articles of incorporation, bylaws or other agreement, to provide for the payment of expenses incurred by an officer or director in defending any civil or criminal action, suit or proceeding as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification by the corporation.

        Section 78.752 of the NRS permits a corporation to purchase and maintain insurance or make other financial arrangements on behalf of the corporation's current and former officers, directors, employees or agents, or any persons serving or who have served in certain capacities at the request of

A corporation may pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if: (1) the director furnishes the corporation a written affirmation of his good faith belief that he has met the standard of conduct described in the preceding sentence; and (2) the director furnishes the corporation an undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct; and (3) a determination is made that the facts then known to those making the determination would not preclude indemnification. Unless a corporation's articles of incorporation provide otherwise, the corporation may indemnify and advance expenses to an officer, employee or agent of the corporation who is not a director to the same extent as to a director. A corporation may not indemnify a director (x) in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation; or (y) in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him. Unless limited by its articles of incorporation, a New Hampshire corporation must indemnify a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he is or was a director or officer of the corporation against reasonable expenses incurred by him in connection with the proceeding.

        The Articles of Incorporation and bylaws of Bow Equipment Leasing Company, Inc. are silent as to indemnification.

West Virginia

Perland Construction, Inc. is incorporated under the laws of West Virginia.

        The West Virginia Business Corporation Act ("WVBCA") empowers a corporation to indemnify an individual made a party to a proceeding because he is or was a director against liability incurred in the proceeding if: (1) (A) he conducted himself in good faith; (B) he reasonably believed (i) in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests and (ii) in

all other cases, that his conduct was at least not opposed to its best interests; and (C) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful; or (2) he engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation. A corporation may not indemnify a director (x) in connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding or (y) in connection with any other proceeding with respect to conduct for which he was adjudged liable on the basis that he received financial benefit to which he was not entitled, whether or not involving action in his official capacity. A corporation must indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he is or was a director of the corporation against reasonable expenses incurred by him in connection with the proceeding. Under the WVBCA, a corporation may pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if: (1) the director furnishes the corporation a written affirmation of his good faith belief that he has met the relevant standard of conduct; and (2) the director furnishes the corporation a written undertaking to repay the advance if the director is not entitled to mandatory indemnification under the WVBCA and it is ultimately determined that he did not meet the relevant standard of conduct. A corporation may indemnify and advance expenses to an officer of the corporation to the same extent as to a director. A corporation may also purchase and maintain on behalf of a director or officer of the corporation insurance against liabilities incurred in such capacities, whether or not the corporation would have the power to indemnify him against the same liability under the WVBCA.

        The Articles of Incorporation and bylaws of Perland Construction, Inc. are silent as to indemnification.

Item 21.    Exhibits and Financial Statement Schedules

(a)   Exhibits.

Reference is made to the Index to Exhibits filed as a part of this registration statement.

(b)   Financial Statement Schedules.

All schedules have been omitted because they are not applicable or because the required information is shown in the financial statements or notes thereto.

Item 22.    Undertakings.The undersigned registrants hereby undertake:

        (a)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

          (i)  to include any prospectus required by Section 10(a)(3) of the Securities Act;

         (ii)  to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

        (iii)  to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

        (b)   That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (c)   To remove from the registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

        (d)   That, for purposes of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

        (e)   That, for the purpose of determining liability of the registrants under the Securities Act to any purchaser in the initial distribution of the securities: The undersigned registrants undertake that in a primary offering of securities of the undersigned registrants pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrants will each be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

          (i)  any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;

         (ii)  any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrants;

        (iii)  the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrants; and

        (iv)  any other communication that is an offer in the offering made by the undersigned registrants to the purchaser.

        (f)    Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrants pursuant to the provisions described in Item 20, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

        (g)   To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), or 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the date of the registration statement through the date of responding to the request.

        (h)   To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

        (i)    That, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
