WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,

SUBSIDIARY GUARANTORS LISTED ON THE FIRST PAGE OF THIS PROSPECTUS,

FOR (WHICH WE REFER TO AS THE OLD NOTES) $500,000,000 AGGREGATE
PRINCIPAL AMOUNT OF OUR 6³/4% SENIOR NOTES DUE 2015

CUSIP No. 858119 AG5 (U.S.)
CUSIP No. U85795 AC3 (Offshore)

The Exchange Offer will expire at 5:00 p.m. New York City Time, on January 9, 2008 (the end of the 20^th business day following the date of this prospectus), unless we extend the exchange offer in our sole and absolute discretion.

We hereby offer, upon the terms and subject to the conditions set forth in this prospectus and the accompanying letter of transmittal (which together constitute the "exchange offer"), to exchange up to $500,000,000 aggregate principal amount of our 6³/4% Senior Notes due 2015, registered under the Securities Act of 1933, for a like principal amount of our outstanding 6³/4% Senior Notes due 2015, which we issued on April 3, 2007, without registration under the Securities Act. We refer to the old notes and the Exchange Notes collectively as the "notes."

We will not receive any cash proceeds from this exchange offer.

There is no active public trading market for the old notes. We do not intend to apply for listing of the Exchange Notes on any domestic securities exchange or seek approval for quotation through any automated quotation system.

We will issue the Exchange Notes in fully registered form, without coupons, in denominations of $1,000 of principal amount and multiples of $1,000 in excess thereof. We will pay interest on the Exchange Notes each April 1 and October 1. The first interest payment on the Exchange Notes will be due on April 1, 2008 with interest payable from the October 1, 2007 prior payment of interest date on the old notes. We may redeem any of the notes beginning on April 1, 2011 at redemption prices set forth in this prospectus, plus accrued and unpaid interest, if any, up to but not including the date of redemption. We may also redeem up to 35% of the aggregate principal amount of the outstanding notes before April 1, 2010 with net proceeds of one or more sales of our capital stock at a redemption price equal to 106.750% of the principal amount of the Exchange Notes being redeemed, plus accrued interest.

The terms of the Exchange Notes that we will issue in connection with this exchange offer are identical to the terms of the outstanding old notes in all material respects, except for the elimination of certain transfer restrictions, registration rights and additional interest provisions relating to the outstanding old notes. The Exchange Notes will be issued under the same Indenture as the old notes. See "Summary of the Terms of the Exchange Offer."

See "Risk Factors" beginning on page 9 of this prospectus for a discussion of risks you should consider before participating in this exchange offer.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

Each broker-dealer that receives Exchange Notes for its own account pursuant to this exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The letter of transmittal states that by so acknowledging 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 of 1933, as amended, which we refer to as the "Securities Act." 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 where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the expiration of this exchange offer (as defined herein), we will make this prospectus available to any broker-dealer for use in connection with any such resale. A broker-dealer may not participate in the exchange offer with respect to old notes acquired other than as a result of market-making activities or trading activities. See "Plan of Distribution."

THE DATE OF THIS PROSPECTUS IS DECEMBER 10, 2007

SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

Throughout this prospectus, including documents we may incorporate by reference, we may make statements that express our opinions, expectations, or projections regarding future events or future results, in contrast with statements that reflect historical facts. These predictive statements, which we generally precede or accompany by such typical conditional words as "anticipate," "intend," "believe," "estimate," "plan," "seek," "project" or "expect," or by the words "may," "will," or "should," are intended to operate as "forward looking statements" of the kind permitted by the Private Securities Litigation Reform Act of 1995, incorporated in Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. That legislation protects such predictive statements by creating a "safe harbor" from liability in the event that a particular prediction does not turn out as anticipated.

While we always intend to express our best judgment when we make statements about what we believe will occur in the future, and although we base these statements on assumptions that we believe to be reasonable when made, these forward looking statements are not a guarantee of performance, and you should not place undue reliance on such statements. Forward looking statements are subject to many uncertainties and other variable circumstances, many of which are outside of our control, that could cause our actual results and experience to differ materially from those we thought would occur.

The following listing represents some, but not necessarily all, of the factors that may cause actual results to differ from those we may have anticipated or predicted:

•: cyclical changes in market supply and demand for steel; general economic conditions affecting steel consumption; U.S. or foreign trade policy affecting the price of imported steel, or adverse outcomes of pending and future trade cases alleging unlawful practices in connection with steel imports or exports, including the repeal, lapse or exemptions, from existing U.S. tariffs on imported steel; and governmental monetary or fiscal policy in the U.S. and other major international economies;
•: increased price competition brought about by excess domestic and global steelmaking capacity and imports of low priced steel;
•: consolidation in the domestic and global steel industry, resulting in larger producers with much greater market power to affect price and/or supply;
•: inability to integrate acquired businesses as quickly and effectively as anticipated;
•: changes in the availability or cost of steel scrap or in the availability or cost of steel scrap substitute materials, including pig iron, or other raw materials or supplies which we use in our production processes, as well as periodic fluctuations in the availability and cost of electricity, natural gas or other utilities;
•: the occurrence of unanticipated equipment failures and plant outages or the occurrences of extraordinary operating expenses;
•: margin compression resulting from our inability to pass increases in costs of raw materials and supplies through to our customers, through price increases or surcharges;
•: loss of business from one or more of our major customers or end-users;
•: labor unrest, work stoppages and/or strikes involving our own workforce, those of our important suppliers or customers, or those affecting the steel industry in general;
•: the effect of the elements upon our production or upon the production or needs of our important suppliers or customers;
•: the impact of, or changes in, environmental laws or in the application of other legal or regulatory requirements upon our production processes or costs of production or upon those of

our suppliers or customers, including actions by government agencies, such as the U.S. Environmental Protection Agency or the Indiana Department of Environmental Management, on pending or future environmentally related construction or operating permits;

•: private or governmental liability claims or litigation, or the impact of any adverse outcome of any litigation on the adequacy of our reserves, the availability or adequacy of our insurance coverage, our financial well-being or our business and assets;
•: changes in interest rates or other borrowing costs, or the effect of existing loan covenants or restrictions upon the cost or availability of credit to fund operations or take advantage of other business opportunities;
•: changes in our business strategies or development plans which we may adopt or which may be brought about in response to actions by our suppliers or customers, and any difficulty or inability to successfully consummate or implement as planned any planned or potential projects, acquisitions, joint ventures or strategic alliances; and
•: the impact of regulatory or other governmental permits or approvals, litigation, construction delays, cost overruns, technology risk or operational complications upon our ability to complete, start-up or continue to profitably operate a project or a new business, or to complete, integrate and operate any potential acquisitions as anticipated.

We also believe that you should read the many factors described in "Risk Factors" to better understand the risks and uncertainties inherent in our business and underlying any forward looking statements.

Any forward looking statements which we make in this prospectus or in any of the documents that are incorporated by reference herein speak only as of the date of such statement, and we undertake no ongoing obligation to update such statements. Comparisons of results between current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

MARKET DATA

We obtained market and competitive position data used in this prospectus, including documents we incorporate by reference, from internal surveys, market research, publicly available information and industry publications. Industry publications generally state that the information contained therein has been obtained from sources believed to be reliable, but that the accuracy and completeness of such information is not guaranteed. Similarly, internal surveys, industry forecasts and market research, while believed to be reliable, have not been independently verified.

Steel Dynamics

We are one of the largest steel producers in the United States based on an estimated annual steelmaking capability of approximately 5.2 million tons, with actual 2006 shipments from steel operations totaling 4.8 million tons. Our 2006 consolidated shipments, excluding shipments between our operating divisions, totaled 4.7 million tons. During 2006, our net sales and net income were $3.2 billion and $396.7 million, respectively, and for the nine months ended September 30, 2007 our net sales and net income were $2.9 billion and $296.7 million, respectively.

We currently have three reporting segments. Prior to April 2006, our operations consisted of two reporting segments:steel operations and steel scrap substitute operations. However, on April 11, 2006, we consummated the acquisition of Roanoke Electric Steel Corporation ("Roanoke Electric") and thereby acquired three additional joist fabrication facilities, which, when added to our two existing New Millennium Building Systems joist and deck fabrication facilities, comprised a third reporting segment:steel fabrication operations. With the addition of two Roanoke Electric steel scrap processing facilities, the subsequent acquisition of two East Tennessee steel scrap processing facilities and the October 26, 2007 acquisition of OmniSource Corporation, we have since renamed our steel scrap substitute operations segment assteel scrap and scrap substitute operations.

•: Steel Operations. Steel operations include our Flat Roll Division, which operates plants in Butler and Jeffersonville, Indiana; our Structural and Rail Division, which operates a plant in Columbia City, Indiana; our Engineered Bar Products Division, which operates a plant in Pittsboro, Indiana; our Roanoke Bar Division, which operates a plant in Roanoke, Virginia; our Steel of West Virginia ("SWVA") operations, which operate plants in Huntington, West Virginia and Memphis, Tennessee, and the Techs Division, which operates three steel galvanizing facilities in the Pittsburgh area. These operations consist primarily of mini-mills, producing steel from steel scrap, using electric arc furnaces, continuous casting and automated rolling mills, but also include facilities which galvanize or otherwise coat steel produced by us or others. Steel operations accounted for 89% of our consolidated net sales during 2006.

The Flat Roll Division sells a broad range of hot rolled, cold rolled and coated steel products, including a large variety of specialty products such as light gauge hot-rolled, galvanized, and painted products. The Structural and Rail Division sells structural steel beams and pilings and is also designed to produce and sell a variety of standard and premium-grade rail for the railroad industry. The Engineered Bar Products Division primarily sells special bar quality and merchant bar quality rounds and round-cornered squares. The Roanoke Bar Division sells billets and merchant steel products, including angles, plain rounds, flats and channels. SWVA primarily sells merchant beams, channels and specialty structural steel sections. The Techs specializes in the galvanizing of specific types of flat-rolled steels in non-automotive applications. Our steel operations sell directly to end users and service centers. These products are used in numerous industry sectors, including the automotive, construction, commercial, transportation and industrial machinery markets.

•: Steel Fabrication Operations. Steel fabrication operations include our five New Millennium Building Systems plants located in Butler, Indiana; Lake City, Florida; Salem, Virginia; Florence, South Carolina; and Continental, Ohio. The operations located in Salem, Florence and Continental were acquired in 2006 pursuant to the acquisition of Roanoke Electric. Revenues from these plants are generated from the fabrication of trusses, girders, steel joists and steel decking used within the non-residential construction industry. Fabrication operations accounted for 8% of our consolidated net sales during 2006.
•: Steel Scrap and Scrap Substitute Operations. Steel scrap and scrap substitute operations include the revenues and expenses associated with (i) our two steel scrap processing locations acquired in April 2006 through the acquisition of Roanoke Electric, two East Tennessee scrap processing

facilities we acquired during the second quarter of 2007, and approximately forty-two additional scrap processing, brokerage and industrial scrap management facilities we acquired with the October 26, 2007 purchase of OmniSource Corporation, and (ii) our scrap substitute manufacturing facility, Iron Dynamics. Ferrous material output from these operations may be used as raw materials within our steel operations or sold to outside consumers, while non-ferrous materials are all sold to outside consumers.

Recent Developments

Senior Unsecured Notes Financings

On April 3, 2007, we completed a $500 million 6³/4% senior unsecured notes offering, due 2015. This exchange offer is related to the issuance of these notes. The net proceeds of this offering were used to redeem our existing $300 million 9¹/2% Senior Unsecured Notes due 2009, to repay certain then outstanding amounts under our senior secured revolving credit facility, to finance certain capital expenditures and for general corporate purposes.

On October 12, 2007, we completed a $700 million 7³/8% senior unsecured notes financing, due 2012. We used the net proceeds of that offering to finance our acquisition of OmniSource Corporation on October 26, 2007 and to repay a portion of the amounts outstanding under our senior secured revolving credit facility.

Both senior unsecured notes offerings were effected in transactions exempt from the registration requirements of the Securities Act and were, therefore, not registered thereunder nor under any state securities laws. Both financings were subject to registration rights agreements requiring us to effect a registered exchange offer or a shelf registration within nine months of each closing date. This prospectus relates solely to the $500 million 6³/4% senior unsecured notes.

Term Loan A Facility

On September 11, 2007, we entered into Amendment No. 2 to our Amended and Restated Credit Agreement (the "Existing Credit Agreement"), under the terms of which certain of our Lender Banks made available to us a term loan A facility in an aggregate principal amount of $550 million ("Term Loan A"). The proceeds of the Term Loan A were utilized to repay a portion of our revolving credit advances under our Existing Credit Agreement and to pay related fees and expenses associated with the Term Loan A. The Term Loan A accrues interest designated on a pricing grid which is adjusted based on our leverage at the time of borrowing with a minimum price of LIBOR plus 1.00% and a maximum price of LIBOR plus 1.75%. The outstanding principal of the Term Loan A is amortized in equal quarterly installments of 2.5% of the original principal amount of the Term Loan A, with the balance payable in full on June 19, 2012. The Term Loan A is secured, on a pro rata basis, by the same collateral as secures our other indebtedness under our Existing Credit Agreement. In addition, so long as the Term Loan A is outstanding, interest accruing on advances under our Revolving Credit Facility will be increased to the interest rate applicable to the Term Loan A. At such time as the Term Loan A has been paid in full, the interest rate on our Revolving Credit Facility will be reduced to levels set forth in the original pricing grid contained in the Existing Credit Agreement.

The Techs Acquisition

On July 2, 2007, we purchased The Techs Holdings, Inc. and The Techs Industries, Inc., or The Techs, a Pennsylvania-based flat-rolled steel galvanizing company that operates three hot-dip galvanizing facilities in the Pittsburgh area, GalvTech, MetalTech and NexTech. We paid approximately $373.4 million for the company, including expenses, after taking into account certain purchase price adjustments. As of September 30, 2007, total assets of The Techs were $496.4 million, of which $337.7 million were intangible assets. The Techs is a non-union company, which was privately held, and

shipped 958,000 tons of galvanized steel in 2006. The three facilities have a combined annual capacity to galvanize approximately 1,000,000 tons.

OmniSource Corporation Acquisition

On October 2, 2007, we signed a stock purchase agreement to acquire OmniSource Corporation, or OmniSource, one of North America's largest scrap recycling companies, a privately held company headquartered in Fort Wayne, Indiana. On October 26, 2007, we consummated that purchase. We paid approximately $425 million in cash, issued 9.7 million shares of our common stock and assumed certain liabilities, including net debt, of approximately $220 million. We financed the cash portion of the purchase with cash on hand and through debt.

OmniSource will operate as a wholly-owned subsidiary and will continue to serve the ferrous and nonferrous scrap processing, brokerage and industrial scrap management needs of its customers, as well as our own ferrous scrap needs. We intend to consolidate our existing scrap operations in Virginia and Tennessee, as well as our planned scrap processing facility now under construction in Indianapolis, Indiana, into OmniSource.

OmniSource President and CEO, Daniel Rifkin, has joined our management team as an Executive Vice President and has been appointed to our Board of Directors. Mr. Rifkin will lead all of the combined companies' ferrous and nonferrous processing and brokerage activities.

OmniSource employs more than 2,000 people in its 42 facilities located in the Midwest and in the eastern United States and Canada, of which approximately 20% are represented by labor unions. OmniSource engages in both ferrous and nonferrous scrap metal processing, transportation, marketing, brokerage and scrap management and consulting services in North America. In addition, OmniSource designs, installs and manages customized programs for industrial manufacturing companies at more than 100 locations throughout North America. Customers include automotive OEMs and suppliers, steel processors, steel mills, foundries, wire and cable producers, utilities and telephone networks.

RISK FACTORS

You should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Any of the following risks could materially and adversely affect our business, financial condition or results of operations. In such case, the trading price of the Notes could decline, and you may lose all or part of your investment. This prospectus and the information incorporated by reference herein also contain forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks described below and elsewhere in this prospectus.

Risks Related to Our Industry

In recent years, imports of steel into the United States have adversely affected, and may yet again adversely affect, U.S. steel prices, which would impact our sales, margins and profitability.

Excessive imports of steel into the United States as a result of excess world supply, have in recent years exerted, and may again in the future exert, downward pressure on U.S. steel prices and significantly reduce our sales, margins and profitability. U.S. steel producers compete with many foreign producers. Competition from foreign producers is typically strong, is periodically exacerbated by weakening of the economies of certain foreign steelmaking countries, and is further intensified during periods when the U.S. dollar is strong relative to foreign currencies. Greater steel exports to the United States tend to occur at depressed prices when steel producing countries experience periods of economic difficulty, decreased demand for steel products or excess capacity.

In addition, we believe the downward pressure on, and periodically depressed levels of U.S. steel prices in some recent years have been further exacerbated by imports of steel involving dumping and subsidy abuses by foreign steel producers. Some foreign steel producers are owned, controlled or subsidized by foreign governments. As a result, decisions by these producers with respect to their production, sales and pricing are often influenced to a greater degree by political and economic policy considerations than by prevailing market conditions, realities of the marketplace or consideration of profit or loss. However, while some tariffs and quotas are currently in effect for certain steel products imported from a number of countries that have been found to have been unfairly pricing steel imports to the U.S., many of these are set to expire shortly or are likely to be repealed. For example, the International Trade Commission in December 2006, as part of its five year review cycle of various steel import duties, voted to revoke all tariffs and countervailing duties on carbon steel plate from 16 countries, and voted to end tariffs on corrosion resistant galvanized steel sheet imported from Canada,

France, Australia and Japan. When such tariffs or duties expire or if others are further relaxed or repealed, or if relatively higher U.S. steel prices enable foreign steelmakers to export their steel products to the United States, even despite the presence of duties or tariffs, the resurgence of substantial imports of foreign steel could again create downward pressure on U.S. steel prices.

China's current steelmaking overcapacity coupled with a reduction or slowdown in China's steel consumption could have a material adverse effect on domestic and global steel pricing and could result in increased steel exports into the United States.

A significant factor in the worldwide strengthening of steel pricing over the past several years has been the explosive growth in Chinese steel consumption, which had until recently vastly outpaced that country's capacity to produce steel in sufficient quantity to serve its internal demand, particularly during 2004. The shortage of Chinese domestic steel supply resulted not only in heightened Chinese demand for imported steel and other raw materials, with a consequent upward spiral in worldwide steel pricing, but also led to a rapid and significant expansion of steel production capacity in China. That, in addition

to the existence of a large amount of outdated, inefficient and government subsidized production capacity, has resulted in a situation in which China's steel producing capacity currently substantially exceeds that country's demand for certain steel products. A combination of a slowdown in China's economic growth rate and its consumption of steel, coupled with its own expansion of steelmaking capacity, has caused a reduction in, and could result in a substantial weakening of, both domestic and global steel demand and steel pricing. Should Chinese steelmaking capacity further increase or its demand weaken, China might not only become a net exporter of steel but many Asian and European steel producers whose steel output currently feeds China's steel import needs could find their way into the U.S. market, through increased steel imports, thus causing an erosion of margins and a reduction in pricing. In fact, in February 2007, the United States initiated legal action against China before the World Trade Organization, alleging that Chinese government subsidies and tax laws give Chinese steel mills and unfair advantage, and the European Confederation of Iron and Steel Industries has petitioned the European Union Commission to take anti-dumping action against Chinese imports.

Increases in prices and limited availability of raw materials and energy may constrain operation levels and reduce profit margins.

Steel producers require large amounts of raw materials, the principal raw materials being scrap metal and scrap substitute products such as pig iron or pelletized iron. Although our developing and our planned vertical integration into ironmaking and into the metals recycling business may enable us to be our own source for some of our metallics requirements, we will still need to rely on other metallics and raw material suppliers, as well as general industry supply conditions. The availability and prices of raw materials may also be negatively affected by new laws and regulations, allocation by suppliers, interruptions in production, accidents or natural disasters, changes in exchange rates, worldwide price fluctuations, and the availability and cost of transportation. Steel producers also consume large amounts of energy. The prices for and availability of electricity, natural gas, oil and other energy resources are all subject to volatile market conditions, often affected by weather conditions as well as political and economic factors beyond our control.

Over the last several years, prices for raw materials and energy have increased significantly, in many cases by a greater margin than corresponding price increases for the sale of steel products. Our inability to recoup such cost increases from increases in the selling prices of steel products, or our inability to pass on all or any substantial part of such cost increases through scrap or other surcharges or to provide for our customers' needs because of the potential unavailability of key raw materials or other inputs, may result in production curtailments or may otherwise have a material adverse effect on our business, financial condition, results of operations or prospects.

Our level of production and our sales and earnings are subject to significant fluctuations as a result of the cyclical nature of the steel industry, the scrap metal recycling industry and some of the industries we serve.

The steel manufacturing business and the scrap metal recycling business are both cyclical in nature and the price of the steel we make or the steel scrap we utilize to manufacture that steel may fluctuate significantly due to many factors beyond our control. With our planned acquisition of OmniSource, a significant portion of our revenues and our operating results will also be dependent upon both ferrous and nonferrous scrap metal sales to other steel mills and foundries for use in their manufacturing operations. The timing and magnitude of these price fluctuations are difficult to predict and may directly affect our product mix, production volumes and our sales and earnings.

The sale of our manufactured steel products is directly affected by demand for our products in other cyclical industries, such as the automotive, oil and gas, gas transmission, residential and commercial/industrial construction, commercial equipment, rail transportation, appliance, agricultural and durable goods industries. Currently, the domestic automotive industry, which is a major consumer of new steel and a major generator of steel scrap, is suffering from a substantial downturn, and

continued economic difficulties, stagnant economies, supply/demand imbalances and currency fluctuations in the United States or globally could further decrease the demand for our products or increase the amount of imports of steel into the United States, which would decrease our sales, margins and profitability. We are also particularly sensitive to trends and events, including strikes and labor unrest that may adversely impact these industries. These industries are significant markets for our products and are themselves highly cyclical. Similarly, but not necessarily paralleling the price fluctuations in the steel business, the purchase prices for automobile bodies and various other grades of obsolete and industrial scrap, as well as the selling prices for processed and recycled scrap metals we plan to utilize in our own manufacturing process or, upon the closing of the OmniSource transaction, we plan to resell to others, are or may be highly volatile and beyond our control. As a metals recycler, we may attempt to respond to changing recycled metal selling prices by adjusting the scrap metal purchase prices we would pay, but our ability to do this may be limited by competitive or other factors and this, in turn, could adversely affect our sales and profitability.

Some of our operations entail significant risk of injury or death.

Steelmaking and the collection, processing and transportation of scrap metal, by reason of the nature of the machinery and processes utilized, are activities that present inherent dangers of injury or death to employees, customers or visitors, in spite of safety precautions, training and compliance with federal, state and local health and safety regulations. While we have in place and intend to continuously maintain policies and procedures to minimize these risks, we may nonetheless be unable to avoid material liabilities for an injury or death, which could adversely affect our results of operations and financial condition.

Risks Relating to our Business

Our senior secured credit agreement contains, and any future financing agreements may contain, restrictive covenants that may limit our flexibility.

Restrictions and covenants in our existing debt agreements, including our senior secured credit agreement and any future financing agreements, may impair our ability to finance future operations or capital needs or to engage in other business activities. Specifically, these agreements restrict our ability to:

•: incur additional indebtedness;
•: pay dividends or make distributions with respect to our capital stock;
•: repurchase or redeem capital stock;
•: make some investments;
•: create liens and enter into sale and leaseback transactions;
•: make some capital expenditures;
•: enter into transactions with affiliates or related persons;
•: issue or sell stock of certain subsidiaries;
•: sell or transfer assets; and
•: participate in some joint ventures, acquisitions or mergers.

A breach of any of the restrictions or covenants could cause a default under our senior secured credit agreement, other debt or the Notes. A significant portion of our indebtedness then may become immediately due and payable.

We may face significant price and other forms of competition from other steel producers, which could have a material adverse effect on our business, financial condition, results of operation or prospects.

The global markets in which steel companies conduct business are highly competitive and are becoming even more so due to increasing consolidation in the steel industry. Increased competition could cause us to lose market share, increase expenditures or reduce pricing, any one of which could have a material adverse effect on our business, financial condition, results of operations or prospects. The global steel industry has historically suffered from substantial over-capacity, and excess capacity in some of our products will intensify price competition for such products. This could cause us to reduce the price for our products and, as a result, have a material adverse effect on our business, financial condition, results of operations or prospects. We compete primarily on the basis of quality and the ability to meet our customers' product needs, delivery schedules and price, and some of our competitors may have advantages due to greater capital resources, different technologies, lower raw material and energy costs or favorable exchange rates.

We may be unable to pass on increases in the cost of steel scrap and other raw materials to our customers which would reduce our earnings.

If we are unable to pass on higher steel scrap and other raw material costs to our customers we will be less profitable. We may not be able to adjust our product prices, especially in the short-term, to recover the costs of increases in scrap and other raw material prices. Our principal raw material is scrap metal derived primarily from junked automobiles, industrial scrap, railroad cars, railroad track materials, agricultural machinery and demolition scrap from obsolete structures, containers and machines. The prices for scrap are subject to market forces largely beyond our control, including demand by U.S. and international steel producers, freight costs and speculation. The prices for scrap have varied significantly, may vary significantly in the future and do not necessarily fluctuate in tandem with the price of steel. Moreover, some of our integrated steel producer competitors are not as dependent as we are on scrap as a part of their raw material melt mix, which, during periods of high scrap costs relative to the cost of blast furnace iron used by the integrated producers, give them a raw material cost advantage over mini-mills. In addition, our operations require substantial amounts of other raw materials, including various types of pig iron, alloys, refractories, oxygen, natural gas and electricity, the price and availability of which are also subject to market conditions.

Competition from other materials may have a material adverse effect on our business, financial condition, results of operations or prospects.

In many applications, steel competes with other materials, such as aluminum and plastics (particularly in the automobile industry), cement, composites, glass and wood. Additional substitutes for steel products could adversely affect future market prices and demand for steel products.

Equipment downtime or shutdowns could adversely affect our business, financial condition, results of operations or prospects.

Steel manufacturing processes are dependent on critical steelmaking equipment, such as furnaces, continuous casters, rolling mills and electrical equipment (such as transformers), and this equipment may incur downtime as a result of unanticipated failures or other events, such as fires or furnace breakdowns, as well as other unusual and unplanned maintenance requirements. Our manufacturing plants have experienced, and may in the future experience plant shutdowns or periods of reduced production as a result of such equipment failures or other events. These disruptions could have an adverse effect on our operations, customer service levels and financial results.

We may face risks associated with the implementation of our growth strategy.

Our growth strategy subjects us to various risks. As part of our growth strategy, we may expand existing facilities, build additional plants, acquire other businesses and steel assets, enter into joint ventures, or form strategic alliances that we believe will complement our existing business. These transactions will likely involve some or all of the following risks:

•: the difficulty of competing for acquisitions and other growth opportunities with companies having materially greater financial resources than us;
•: the inability to realize anticipated synergies or other benefits expected from an acquisition;
•: the difficulty of integrating the acquired operations and personnel into our existing businesses;
•: the potential disruption of ongoing businesses;
•: the diversion of resources;
•: the inability of management to maintain uniform standards, controls, procedures and policies;
•: the difficulty of managing the growth of a larger company;
•: the risk of entering markets in which we have little experience;
•: the risk of becoming involved in labor, commercial, or regulatory disputes or litigation related to the new enterprise;
•: the risk of becoming more highly leveraged;
•: the risk of contractual or operational liability to other venture participants or to third parties as a result of our participation;
•: the inability to work efficiently with joint venture or strategic alliance partners; and
•: the difficulties of terminating joint ventures or strategic alliances.

These transactions might be required for us to remain competitive, but we may not be able to complete any such transactions on favorable terms or obtain financing, if necessary, for such transactions on favorable terms. Future transactions may not improve our competitive position and business prospects as anticipated, and if they do not our sales and earnings may be significantly reduced.

There are risks associated with the development and operation of new businesses or acquisitions.

We are normally in the process of examining a number of new businesses or potential acquisitions. On July 2, 2007, we acquired The Techs for approximately $373.4 million including expenses. On September 20, 2007, we announced that we are moving forward with our Mesabi Nugget iron-making project to construct the world's first commercial iron-making facility to use Kobe Steel Company's ITmk3® iron-making process, an undertaking involving an investment of approximately $150 million. And on October 26, 2007, we completed the acquisition of OmniSource Corporation, one of the largest scrap processing, brokerage and industrial scrap management companies in North America, for a purchase price of approximately $1.1 billion, which included the assumption and payment of certain OmniSource debt at closing.

The success of any future business or acquisition will depend substantially on our ability to manage the acquired operations successfully and to integrate it with our existing operations in an efficient and effective manner. If we are unable to manage or integrate new operations successfully, our financial results could suffer. Additional risks associated with acquisitions include the diversion of management's attention from other business concerns, the potential loss of key employees and customers of the

acquired companies, the potential assumption of unknown liabilities, the potential risk of increasing the amount of our outstanding indebtedness and the inherent risks in entering markets or lines of business in which we have limited or no prior experience.

Environmental regulation imposes substantial costs and limitations on our operations.

We are subject to the risk of substantial environmental liability and limitations on our operations brought about by the requirements of existing environmental laws and regulations, as currently interpreted or interpreted in the future, or future laws or regulations. We are subject to various federal, state and local environmental, health and safety laws and regulations concerning such issues as air emissions, wastewater discharges, solid and hazardous materials and waste handling and disposal, and the investigation and remediation of contamination. These laws and regulations are increasingly stringent. While we believe that our facilities are, and will continue to be, in material compliance with all applicable environmental laws and regulations, the risks of substantial costs and liabilities related to compliance with these laws and regulations are an inherent part of the business, and it is possible that future conditions may develop, arise or be discovered that create substantial environmental remediation liabilities and costs. For example, steelmaking operations produce some waste products, such as electric arc furnace dust, which are classified as hazardous waste and must be properly disposed of under applicable environmental laws. In addition, there are risks associated with the metals recycling business in which we engage and, with our planned acquisition of OmniSource, which we intend to expand. An unrecyclable material produced from the process of shredding scrap automobiles and other obsolete scrap is a product referred to as shredder fluff. This material must meet certain criteria in order to avoid classification as a hazardous waste, requiring off-site disposal in permitted landfills. While, with our existing scrap metal processing and recycling operations, we endeavor, and believe that OmniSource in its operations endeavors to remove hazardous contaminants from the feed material prior to shredding, and while we employ and, we believe, OmniSource employs adequate source control measures to reasonably ensure that other contaminants do not enter the air, soil or groundwater, we can give no assurance that this will always be successful.

These laws can impose clean up liability on generators of hazardous waste and other substances that are shipped off-site for disposal, regardless of fault or the legality of the disposal activities. Other laws may require us to investigate and remediate contamination at our properties, including contamination that may have been caused in whole or in part by third parties. While we believe we can comply with environmental legislation and regulatory requirements and that the costs of doing so have been and will continue to be included within budgeted cost estimates, it is possible that such compliance will prove to be more limiting and costly than anticipated. In addition to potential clean up liability, in the past we have been, and in the future may become, subject to substantial monetary fines and penalties for violation of applicable laws, regulations or administrative conditions. In May 2007, we received notice of hazardous waste violations alleged by the federal Environmental Protection Agency at our Huntington, West Virginia plant with respect to which the agency has proposed a $250,000 penalty and certain corrective actions. We may also be subject from time to time to legal proceedings brought by private parties or governmental agencies with respect to environmental matters, including matters involving alleged property damage, personal injury or health claims.

We must also obtain and continue to comply with various permits and licenses to conduct our steelmaking, current and planned scrap recycling and our proposed ironmaking operations and projects. Failure to obtain or the violation of any permit or license, if not remedied, could result in substantial fines, suspension of operations or closure of a facility or site.

Technology, operating and start-up risks associated with our announced Mesabi Nugget project may prevent us from realizing the anticipated benefits and could result in a loss of our investment.

While we and certain other current and former joint venture partners built and operated a successful small scale pilot project in Minnesota using Kobe Steel's proprietary ITmK3's iron-making process to produce a cost effective iron nugget product, which we plan to utilize as a scrap substitute feed-stock in our steel making operations, we have no assurance that the full scale commercial plant we recently announced, in which we will be the dominant investor and owner, will be successful. Although, we believe that a full scale commercial plant should be capable of consistently producing high-quality iron nuggets in sufficient quantities and at a cost that will compare favorably with the cost of steel scrap and scrap substitute products, including pig iron, there can be no assurance that these expectations can be achieved. If we proceed with this project, which could entail an investment in excess of $150 million, and if we thereafter encounter cost overruns, construction delays or systems or process difficulties during or after start-up, the anticipated capital costs could materially increase, the expected operating cost benefits from the development of this iron nugget product could be diminished or lost, and we could also lose our investment in the project. Moreover, we may undertake certain ancillary ventures related to the iron-making process, such as the mining and concentrating of taconite ore, a business in which we have no experience and that could entail substantial additional investment with no guarantees of success.

We may not be able to negotiate some future labor contracts on acceptable terms, which could result in strikes or labor actions.

While only some 10% of our employees, all in a single business unit, are represented by unions, approximately 20% of OmniSource's employees comprising eleven of OmniSource's forty-two facilities, are represented by unions. As agreements with those unions expire, we may not be able to negotiate extensions or replacements of such agreements on terms acceptable to us. Any failure to reach agreement could result in strikes, lockouts or other labor actions, including work slowdowns or stoppages and could have a material adverse effect on our operations.

Risks Related to the Notes

We may not have sufficient cash flow to make payments on the Notes and our other debt.

After giving effect to (a) the incurrence of $550 million under our term loan A facility to repay borrowings under our revolving credit facility, including $373.4 million borrowed for the acquisition of The Techs, (b) the completion of our $500 million senior unsecured notes financing on April 3, 2007 and the application of the net proceeds therefrom, and (c) the completion of our $700 million senior unsecured notes financing on October 12, 2007, and the application of the net proceeds therefrom, as of September 30, 2007, we would have had $1.8 billion of indebtedness, which would have represented approximately 63% of our total consolidated capitalization, including current maturities of long-term debt.

Our ability to pay principal and interest on the Notes and our other debt and to fund our planned capital expenditures depends on our future operating performance. Our future operating performance is subject to a number of risks and uncertainties that are often beyond our control, including general economic conditions and financial, competitive, regulatory and environmental factors. For a discussion of some of these risks and uncertainties, please see "Risk Factors—Risks Related to Our Business" and "—Risks Related to Our Industry." Consequently, we cannot assure you that we will have sufficient cash flow to meet our liquidity needs, including making payments on our indebtedness.

If our cash flow and capital resources are insufficient to allow us to make scheduled payments on the Exchange Notes or our other debt, we may have to sell assets, seek additional capital or restructure

or refinance our debt. We cannot assure you that the terms of our debt will allow for these alternative measures or that such measures would satisfy our scheduled debt service obligations.

If we cannot make scheduled payments on our debt:

•: our debtholders could declare all outstanding principal and interest to be due and payable;
•: the lenders under our senior secured credit agreement could terminate their commitments and commence foreclosure proceedings against our assets;
•: we could be forced into bankruptcy or liquidation; and
•: you could lose all or part of your investment in the Notes.

The amount of our indebtedness may limit our financial and operating flexibility. For example, it could:

•: make it more difficult to satisfy our obligations with respect to our debt, including the Notes;
•: limit our ability to obtain additional financing for working capital, capital expenditures, acquisitions or general corporate purposes;
•: require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, reducing our ability to use these funds for other purposes;
•: limit our ability to adjust rapidly to changing market conditions; and
•: increase our vulnerability to downturns in general economic conditions or in our business.

Despite the level of our indebtedness, we may still incur significantly more debt, which could further increase the risks described above.

The terms of our senior secured credit agreement limit but do not prohibit us or our subsidiaries from incurring additional indebtedness in the future, and on September 11, 2007, we amended that agreement to open the Term Loan A facility described in this prospectus. Moreover, the terms of the Exchange Notes do not limit our ability to incur additional unsecured indebtedness, and on October 12, 2007, we completed an additional ($700 million) senior unsecured notes financing. If new indebtedness is added to our and our subsidiaries' current debt levels, the related risks that we and they now face could intensify, and we may not be able to meet all our debt obligations, including repayment of the Exchange Notes, in whole or in part. Subject to certain limitations, any additional debt could also be secured or incurred by our non-guarantor subsidiaries which could increase the risks described above.

Your right to receive payments on the Exchange Notes is effectively subordinated to the rights of our and the Subsidiary Guarantors' existing and future secured creditors. Further, your right to receive payments on the Exchange Notes is effectively subordinated to all our non-guarantor subsidiaries' existing and future indebtedness.

Our obligations under the Exchange Notes are unsecured. Holders of our secured indebtedness, including indebtedness under our senior secured credit agreement, and the secured indebtedness of the Subsidiary Guarantors will have claims that are before your claims as holders of the Exchange Notes to the extent of the value of the assets securing that other indebtedness. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding up, liquidation, reorganization, or other bankruptcy proceeding, holders of our secured indebtedness will have a prior claim to those of our assets that constitute their collateral. 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. In any of the foregoing events, we cannot assure you that

there will be sufficient assets to pay amounts due on the Exchange Notes. As a result, holders of the Exchange Notes may receive less, ratably, than holders of secured indebtedness.

Additionally, some but not all of our subsidiaries are guarantors of the Exchange Notes. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us.

We may be prohibited from repurchasing, and may be unable to repurchase, the Exchange Notes upon a change of control, which would cause defaults under the indenture for the Exchange Notes or possibly any of our debt or financing agreements that may be in effect at the time of the change in control.

If we experience a change of control, as that term is defined in the indenture governing the Notes, we will be required to make an offer to repurchase all of the Exchange Notes at 101% of their principal amount plus accrued and unpaid interest, if any, to the date of purchase. We cannot assure you that we will have sufficient funds or be able to arrange for additional financing to repurchase the Exchange Notes following such a change of control. In addition, we can not assure you that a repurchase of the Exchange Notes following such a change in control would be permitted pursuant to any of our debt or financing agreements that would be in effect at the time of such change in control, which could cause our other indebtedness to be accelerated. If such indebtedness were to be accelerated, we may not have sufficient funds to repurchase the Exchange Notes and repay such indebtedness.

We cannot assure you that an active trading market will develop for the Exchange Notes.

The Exchange Notes are a new issue of securities. There is no active public trading market for the Exchange Notes. We do not intend to list the Exchange Notes on any securities exchange or to arrange for them to be quoted on the Nasdaq Global Select Market or any other quotation system. Certain of the Initial Purchasers have advised us that they currently intend to make a market in the Exchange Notes, but they are not obligated to do so and may discontinue their market making activity at any time without notice. If the Exchange Notes are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities, our financial condition and results of operations and various other factors.

Fraudulent conveyance laws could void the guarantees of the Exchange Notes.

Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee could be voided, or claims in respect of a guarantee could 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 either: (i) intended to hinder, delay or defraud any present or future creditor; or (ii) received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and (a) was insolvent or rendered insolvent by reason of the incurrence of the guarantee, (b) was engaged in a business or transaction for which the guarantor's remaining assets constituted unreasonably small capital, or (c) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature. Moreover, any payments made by a Subsidiary Guarantor pursuant to its guarantee could be voided and required to be returned to the Subsidiary Guarantor, or to a fund for the benefit of the creditors of the Subsidiary Guarantor. To the extent that any guarantee is voided as a fraudulent conveyance, the claims of holders of the Exchange Notes with respect to such guarantee would be materially adversely affected.

In addition, a legal challenge of a guarantee on fraudulent conveyance grounds will focus on, among other things, the benefits, if any, realized by the relevant Subsidiary Guarantor as a result of the issuance of the Exchange Notes. The measures of insolvency for purposes of these fraudulent transfer

laws will vary depending upon the governing law. Generally, however, a Subsidiary Guarantor would be considered insolvent if:

•: the sum of its debts, including contingent liabilities, were greater than the fair saleable value of all of its assets; or
•: if the present fair saleable value of its assets were 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.

On the basis of historical financial information, recent operating history and other factors, we believe that the guarantees are being incurred for proper purposes and in good faith and that each Subsidiary Guarantor, after giving effect to its guarantee of the Exchange Notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. There can be no assurance, however, as to what standard a court would apply in making such determinations or that a court would agree with our conclusions in this regard.

Trading prices for the Exchange Notes may be volatile.

Historically, the market for non-investment grade debt securities has been subject to disruptions that have caused substantial volatility in the prices of such securities. The market for the Exchange Notes could be subject to similar volatility. The trading price of the Exchange Notes could also fluctuate in response to factors such as variations in our operating results, general developments in the steel industry, developments in the general economy, and changes in securities analysts' recommendations regarding our securities or similar securities.

SUMMARY OF THE TERMS OF THE EXCHANGE OFFER

The following brief summary contains the material terms of this exchange offer. You should read the full text and more specific details contained elsewhere in this prospectus.

For a more detailed description of the Exchange Notes, see "Description of the Exchange Notes."

Exchange Notes	Up to $500 million aggregate principal amount of our 6³/4% Senior Notes due April 1, 2015 that have been registered under the Securities Act, in exchange for an equal face amount of our outstanding unregistered 6³/4% Senior Notes, the old notes, due April 1, 2015.
	We entered into a registration rights agreement with the initial purchasers of the old notes in which we agreed to register this exchange offer, to deliver this prospectus and to complete the exchange offer. You are entitled to exchange in this exchange offer your old notes for Exchange Notes that have terms identical in all material respects to the old notes, except that:
	•	the Exchange Notes have been registered under the Securities Act;
	•	the Exchange Notes are not entitled to the registration rights that are applicable to the old notes; and
	•	the additional cash interest provisions that apply to the old notes in the event of a failure to timely register and consummate the exchange offer will no longer apply. See "Description of the Notes—Registration Rights."
Expiration Date	The exchange offer will expire at 5:00 p.m., New York City time, on January 9, 2008, unless extended. We do not currently plan to extend the expiration date. Any outstanding old notes not accepted for exchange for any reason will be returned without expense to the tendering holder promptly after the expiration or termination of the exchange offer.
Withdrawal Rights	A tender of outstanding old notes may be withdrawn at any time prior to the expiration date. Any old notes not accepted for exchange for any reason will be returned without expense to the tendering holder promptly after the expiration or termination of the exchange offer.
Resales of the Exchange Notes	Based on an interpretation by the staff of the SEC, set forth in no-action letters issued to various third parties, we believe that Exchange Notes to be issued in the exchange offer in exchange for the old notes may be offered for resale, resold and otherwise transferred by you without compliance with the registration and prospectus delivery provisions of the Securities Act, if you meet the following conditions:
	(1)	the Exchange Notes are acquired by you in the ordinary course of your business;
	(2)	you are not participating, do not intend to participate and have no arrangement or understanding with any person to participate in a distribution of the Exchange Notes; and

	(3)	you are not our affiliate, as that term is defined in Rule 405 under the Securities Act.
	In addition, each participating broker-dealer that receives Exchange Notes in the exchange offer for its own account in exchange for old notes pursuant to the exchange offer, that were acquired by that broker-dealer as a result of market-making activities or other trading activities must agree to deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Notes. See "Plan of Distribution."
	If you are a holder of old notes, including any broker-dealer, and you are an affiliate of Steel Dynamics, Inc., did not acquire the Exchange Notes in the ordinary course of your business, or you wish to tender your old notes in the exchange offer with the intention of participating, or for the purpose of participating in a distribution of the Exchange Notes, you cannot rely on the position of the staff of the SEC enunciated in Exxon Capital Holdings Corporation, Morgan Stanley & Co. Incorporated or similar no-action letters and, absent an available exemption, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with the resale of the Exchange Notes.
Certain Conditions to the Exchange Offer	The exchange offer is subject to customary conditions, which we may waive. Please read the section captioned "Terms of the Exchange—Certain Conditions to the Exchange Offer" for more information regarding the conditions to the exchange offer.
Effects on Holders of Outstanding Old Notes	As a result of the making of, and upon acceptance for exchange of all validly tendered outstanding old notes pursuant to the terms of, the exchange offer, we will have fulfilled a covenant in the Registration Rights Agreement at the time of the issuance of the old notes and, accordingly, there will thereafter be no increase in the interest rate on the old notes as described in the Registration Rights Agreement. If you are a holder of old notes and you do not tender your old notes in the exchange offer, you will continue to hold the old notes and will be entitled to all the rights and limitations applicable to the old notes in the indenture relating to the notes, except for any rights under the Registration Rights Agreement that by their terms terminate upon the consummation of the exchange offer.
	To the extent that old notes are tendered and accepted in this exchange offer, the trading market for the old notes could be adversely affected.

Consequences of Failure to Exchange	If you do not exchange your old notes for Exchange Notes, you will continue to hold your outstanding old notes and will be entitled to all the rights and subject to all the limitations applicable to the old notes in the Indenture relating to the old notes, except that you will no longer be able to obligate us to register your old notes under the Securities Act. In that event, you will not be able to resell, offer to resell or otherwise transfer your old notes unless they are registered under the Securities Act or unless you resell, offer to resell or otherwise transfer them under an exemption from the registration requirements of, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in connection with this exchange offer, we do not currently anticipate that we will register the old notes under the Securities Act.
Certain Tax Considerations	The exchange of old notes for Exchange Notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes. See "Certain Tax Considerations."
Use of Proceeds	We will not receive any cash proceeds from the issuance of Exchange Notes pursuant to the exchange offer.
Exchange Agent	The Bank of New York Trust Company, N.A. is the exchange agent for the exchange offer. The address and telephone number of the exchange agent are:

Procedure for Exchange	If you wish to accept the exchange offer and would like to receive Exchange Notes for your old notes, you must complete, sign and date the accompanying letter of transmittal or a copy of the letter of transmittal, all in accordance with the instructions contained in this prospectus and the letter of transmittal and deliver the completed letter to the Exchange Agent.
Delivery	You must also deliver the old notes and any other required documents to the Exchange Agent at the address set forth above. If you hold old notes through The Depository Trust Company ("DTC") and wish to participate in the exchange offer, you must comply with the Automated Tender Offer Program procedures of DTC, by which you will agree to be bound by the letter of transmittal. By signing or agreeing to be bound by the letter of transmittal, you will represent to us that, among other things:
	•	any Exchange Notes you receive will be acquired in the ordinary course of your business;

	•	you have no arrangement or understanding with any person or entity to participate in a distribution of the Exchange Notes;
	•	if you are a broker-dealer that will receive Exchange Notes for your own account in exchange for old notes that were acquired as a result of market-making activities or other trading activities, that you will deliver a prospectus, as required by law, in connection with any resale of those Exchange Notes; and
	•	you are not our "affiliate," as defined in Rule 405 of the Securities Act, or, if you are an affiliate, you will comply with any applicable registration and prospectus delivery requirements of the Securities Act.
Special Procedures for Beneficial Owners	If you are the beneficial owner of old notes and they are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, and you wish to tender your old notes, you should promptly contact the person in whose name your old notes are registered and instruct that person to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the person in whose name your old notes are registered. The transfer of registered ownership may take considerable time. See "The Exchange Offer—Procedures for Tendering—Procedures Applicable to All Holders."
Guaranteed Delivery Procedures	If you wish to tender your old notes and your old notes are not immediately available or you cannot deliver your old notes, the accompanying letter of transmittal or any other documents required by the accompanying letter of transmittal or comply with the applicable procedures under DTC's Automated Tender Offer Program before the Expiration Date, you must tender your old notes according to the guaranteed delivery procedures set forth in this prospectus under "Terms of the Exchange Offer—Guaranteed Delivery Procedures."
Shelf Registration Statement	We will use our commercially reasonable efforts to cause the SEC to declare effective a shelf registration statement with respect to the resale of the old notes and to keep the shelf registration statement effective up to two years after the effective date of the shelf registration statement. These circumstances include:
	•	If the exchange offer is not permitted by applicable law or SEC policy;
	•	If the exchange offer has not been or cannot be consummated on or before January 3, 2008;
	•	If any initial purchaser so requests on or prior to the 60^th day after the consummation of the registered exchange offer with respect to the old notes not eligible to be exchanged for the exchange notes and held by it following the consummation of the exchange offer; or

•

If any holder that participates in the exchange offer does not receive freely transferable exchange notes in exchange for tendered old notes in exchange for tendered old notes and so requests on or prior to the 60^th day after the consummation of the registered exchange offer.

Please see "Terms of the Exchange" for detailed instructions on how to obtain Exchange Notes for your old Notes.

SUMMARY OF THE TERMS OF THE EXCHANGE NOTES

The following summary highlights all material information contained elsewhere in this prospectus but does not contain all the information that you should consider before participating in the exchange offer. The "Description of the Notes" section contains a more detailed description of the terms and conditions of the exchange notes. We urge you to read this entire prospectus, including the "Risk Factors" and the consolidated financial statements and related notes.

In the exchange offer you are entitled to exchange your old notes for exchange notes, which are identical in all material respects to the old notes except that:

•: the exchange notes have been registered under the Securities Act and will be freely tradable by persons who are not affiliated with us;
•: the exchange notes are not entitled to the registration rights that are applicable to the old notes under the Registration Rights Agreement; and
•: our obligation to pay additional interest on the old notes if the exchange offer is not consummated by January 3, 2008, does not apply to the exchange notes.

Issuer		Steel Dynamics, Inc.
Notes Offered		$500,000,000 aggregate principal amount of 6³/4% Senior Notes Due 2015
Maturity		April 1, 2015
Interest		6³/4% per annum, payable in cash on April 1 and October 1 of each year, with interest on Exchange Notes beginning on April 1, 2008, payable from October 1, 2007.

Hancock, Jr., LLC, New Millennium Building Systems, Inc., Socar of Ohio, Inc., Steel of West Virginia, Inc., SWVA, Inc., Marshall Steel Inc., Steel Ventures, Inc., Shredded Products II, LLC, The Techs Industries, Inc., The Techs Holdings, Inc., OmniSource Corporation, Admetco, Inc., Auburn Investment Company, LLC, Capitol City Metals, LLC, Carolina Investment Company, LLC, Global Shredding Technologies Ltd., LLC, Industrial Scrap Corporation, Industrial Scrap, LLC, Jackson Iron & Metal Company, Inc., Lucky Strike Metals, LLC, Michigan Properties Ecorse, LLC, OmniSource Athens Division, LLC, OmniSource Mexico, LLC, OmniSource Bay City, LLC, OmniSource Indianapolis, LLC, OmniSource, LLC, OmniSource Transport, LLC, Open Sky Aviation, LLC, Recovery Technologies, LLC, Scientific Recycling Group, LLC, Speedbird Aviation, LLC and Superior Aluminum Alloys, LLC.

Optional Redemption	We may redeem any of the notes beginning on April 1, 2011, at the redemption prices set forth under the heading "Description of the Notes," plus accrued and unpaid interest, if any, to the date of redemption.
	In addition, before April 1, 2010, we may redeem up to 35% of the aggregate principal amount of outstanding notes with the net cash proceeds from sales of our capital stock at a redemption price equal to 106.750% of their principal amount, plus accrued and unpaid interest, if any, to the redemption date.
Change of Control	Upon the occurrence of a change of control (as defined under "Description of the Notes") we will be required to make an offer to purchase the notes. The purchase price will equal 101% of the principal amount of the notes on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase. We may not have sufficient funds available at the time of a change of control to make any required debt payment (including repurchases of the notes).
Ranking	The notes will be senior unsecured obligations. The notes will be equal in right of payment with all of our existing and future senior unsecured indebtedness, including our $700 million of 7³/8% senior unsecured notes, due 2012, which we issued on October 12, 2007, and will rank senior to all existing and future subordinated indebtedness. The notes will be effectively subordinated to our secured indebtedness, to the extent of the assets securing that indebtedness, including indebtedness under our senior secured credit agreement. The notes will effectively rank junior to our non-guarantor subsidiaries' indebtedness and other liabilities, including trade payables. The subsidiary guarantees of the notes will rank equally in right of payment to all existing and future senior secured indebtedness of our Subsidiary Guarantors (as defined under "Description of the Notes").
	As of December 31, 2006, after giving effect to the offering of the old notes and the use of proceeds therefrom, we would have had $555.1 million of consolidated indebtedness outstanding, of which there would have been:
	•	$17.6 million of secured indebtedness, and
	•	$37.5 million of subordinated indebtedness.
	As of December 31, 2006, our non-guarantor subsidiaries had approximately $18.7 million of liabilities outstanding, including $9.7 million of indebtedness, all of which is held by Steel Dynamics.

	As of September 30, 2007, however, after giving effect to the issuance and sale of $700 million of our 7³/8% Senior Notes due 2012 and the application of the net proceeds therefrom to finance the acquisition of OmniSource Corporation on October 26, 2007 and to repay certain outstanding amounts under our senior secured credit agreement, we would have had $1.8 billion of consolidated indebtedness outstanding, which there would have been:
	•	$615.7 million of secured indebtedness;
	•	$37.3 million of subordinated indebtedness;
	•	$500.0 million of unsecured 6³/4% Senior Notes due 2015; and
	•	$700.0 million of unsecured 7³/8% Senior Notes due 2012.
	As of September 30, 2007, our non-guarantor subsidiaries had approximately $30.6 million of liabilities outstanding, including $13.4 million of indebtedness, all of which indebtedness is held by Steel Dynamics, Inc.
Certain Covenants	The terms of the notes limit our ability and the ability of our Significant Subsidiaries (as defined under "Description of Notes") to:
	•	engage in sale-leaseback transactions;
	•	create liens; and
	•	engage in a merger, sale or consolidation.
	These covenants are subject to important exceptions and qualifications, which are described under the heading "Description of the Notes—Certain Covenants" in this prospectus.
Use of Proceeds	We will not receive any cash proceeds upon the completion of the exchange offer.
Further Issuances	We may from time to time, without notice to or the consent of the holders of Exchange Notes, create and issue additional notes ranking equally and ratably with the Exchange Notes. Such further notes may be issued under the Indenture relating to the notes offered hereby, and may vote with the notes offered hereby on matters affecting all noteholders.
Form of Exchange Notes	The Exchange Notes to be issued in the exchange offer will be represented by one or more global securities deposited with the Trustee for the benefit of DTC. You will not receive Exchange Notes in certificated form unless one of the events sets forth under the heading "Description of the Exchange Notes—Form of Exchange Notes" occurs. Instead, beneficial interests in the Exchange Notes to be issued in the exchange offer will be shown on, and a transfer of these interests will be effected only through, records maintained in book entry form by DTC with respect to its participants.

Amendments and Waivers		Except for specified amendments, the Indenture may be amended with the consent of the holders of a majority of the principal amount of the notes then outstanding.
Absence of a Public Market for the Exchange Notes		The Exchange Notes generally will be freely transferable but will also be new securities for which there will not initially be a market. It is not certain whether a market for the Exchange Notes will develop or whether any such market would provide a significant degree of liquidity. We do not intend to apply for a listing of the Exchange Notes on any domestic securities exchange or seek approval for quotation through any automated quotation system.

USE OF PROCEEDS

We will receive no proceeds from the exchange of the old notes in this exchange offer. In consideration for issuing the Exchange Notes as contemplated by this prospectus, we will receive in exchange a like principal amount of old notes. The old notes surrendered in exchange for the Exchange Notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the Exchange Notes will not result in any change in our capitalization.

The net proceeds from the issuance and sale of the old notes were approximately $495.1 million after deduction of the expenses related to the offerings.

TERMS OF THE EXCHANGE OFFER

We are offering to exchange $500 million of our 6³/4% Senior Notes Due April 1, 2015 that have been registered under the Securities Act of 1933, as amended, in exchange for an equal face amount of our outstanding unregistered 6³/4% Senior Notes Due April 1, 2015 that were issued on April 3, 2007.

We will accept up to a maximum face amount of $500 million of validly unregistered old notes.

Except for the requirements of applicable U.S. federal and state securities laws, there are no federal or state regulatory requirements to be complied with or approvals to be obtained by Steel Dynamics in connection with the exchange offers which, if not complied with or obtained, would have a material adverse effect on Steel Dynamics.

We issued the old notes on April 3, 2007 in a private placement to certain initial purchasers pursuant to a Purchase Agreement, and the initial purchasers resold the old notes to a limited number of qualified institutional buyers as defined in Rule 144A under the Securities Act in reliance on that rule, and to non-U.S. persons in offshore transactions in reliance on Regulation S under the Securities Act. On April 3, 2007, we also entered into an original Indenture and have since then entered into several supplemental indentures. We also entered into a Registration Rights Agreement. This agreement requires that we file a registration statement under the Securities Act with respect to the Exchange Notes to be issued in the exchange offer and, upon the effectiveness of the registration statement, offer to you the opportunity to exchange your old notes for a like principal amount of Exchange Notes. These Exchange Notes will be issued without a restrictive legend and, except as set forth below, may be reoffered and resold by you without registration under the Securities Act. After we complete the exchange offer, our obligations with respect to the registration of the notes will terminate, except as provided in the last paragraph of this section. A copy of the original and the supplemental indentures relating to the notes, and the Registration Rights Agreement have been incorporated by reference into or attached as exhibits to the registration statement of which this prospectus is a part.

Based on an interpretation by the staff of the Commission set forth in no-action letters issued to third parties, if you are not our "affiliate" within the meaning of Rule 405 under the Securities Act or a broker-dealer referred to in the next paragraph, we believe that Exchange Notes to be issued to you in the exchange offer may be offered for resale, resold and otherwise transferred by you, without compliance with the registration and prospectus delivery provisions of the Securities Act. This interpretation, however, is based on your representation to us that:

•: the Exchange Notes to be issued to you in the exchange offer are acquired in the ordinary course of your business;
•: you are not engaging in and do not intend to engage in a distribution of the Exchange Notes to be issued to you in the exchange offer; and
•: you have no arrangement or understanding with any person to participate in the distribution of the Exchange Notes to be issued to you in the exchange offer.

If you tender your old notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes to be issued to you in the exchange offer, you cannot rely on this interpretation by the staff of the Commission. Under those circumstances, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. Each broker-dealer that receives Exchange Notes in the exchange offer for its own account in exchange for old notes that were acquired by the broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of those Exchange Notes. See "Plan of Distribution."

In the event that applicable interpretations of the staff of the Securities and Exchange Commission do not permit Steel Dynamics to effect the Exchange Offer, or under other specified circumstances, we will use our best efforts, at our cost, to cause to become effective a shelf registration statement with respect to resale of the notes. We will use our best efforts to keep such shelf registration statement effective until the expiration of the time period referred to in Rule 144(k) under the Securities Act after the Closing Date, or such shorter period that will terminate when all notes covered by a shelf registration statement have been sold pursuant to a shelf registration statement. In the event of such a shelf registration, we will provide to each holder copies of the prospectus, notify each holder when the shelf registration statement for the notes has become effective and take certain other actions as are required to permit resale of the notes. A holder that sells its notes pursuant to the shelf registration statement (1) generally will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, (2) will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and (3) will be bound by the provisions of the registration rights agreement that are applicable to such a holder (including certain indemnification obligations).

In the event that the exchange offer is not consummated on or prior to the date that is nine months after the Closing Date, the annual interest rate borne by the notes will be increased by .5% over the rate shown on the cover page of this prospectus. Once the exchange offer is consummated or the shelf registration statement is declared effective, the annual interest rate borne by the notes shall be changed to again be the rate shown on the cover page of this prospectus.

Consequences of Failure to Exchange

After we complete the exchange offer, if you have not tendered your old notes, you will not have any further registration rights, except as set forth above. Your old notes will continue to be subject to certain restrictions on transfer. Therefore, the liquidity of the market for your old notes could be adversely affected upon completion of the exchange offer if you do not participate in the exchange offer.

THE EXCHANGE

Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, we will accept any and all old notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date of January 9, 2008, unless extended. 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. You may tender some or all of your old notes pursuant to the exchange offer. However, old notes may be tendered only in integral multiples of $1,000 principal amount.

The form and terms of the Exchange Notes are substantially the same as the form and terms of the old notes, except that the Exchange Notes to be issued in the exchange offer have been registered under the Securities Act and will not bear legends restricting their transfer. The Exchange Notes will be issued pursuant to, and entitled to the benefits of, the Indenture. The Indenture also governs the old notes. The Exchange Notes and the old notes will be deemed one issue of notes under the indenture.

As of the date of this prospectus, $500.0 million in aggregate principal amount of 6³/4% old notes due 2015 were outstanding. This prospectus, together with the letter of transmittal, is being sent to all registered holders and to others believed to have beneficial interests in the old notes. You do not have any appraisal or dissenters' rights in connection with the exchange offer under the Business Corporation Law of the State of Indiana or the Indenture.

We will be deemed to have accepted validly tendered outstanding 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 our agent for the tendering holders for the purpose of receiving the Exchange Notes from us. If we do not accept any tendered notes because of an invalid tender, the occurrence of certain other events set forth in this prospectus or otherwise, we will return certificates for any unaccepted old notes, without expense, to the tendering holder as promptly as practicable after the expiration date.

You will not be required to pay brokerage commissions or fees or, except as set forth below under "—Transfer Taxes," transfer taxes with respect to the exchange of your old notes in the exchange offer. We will pay all charges and expenses, other than certain applicable taxes, in connection with the exchange offer. See "—Fees and Expenses" below.

Expiration Date; Amendments

The exchange offer will expire at 5:00 p.m., New York City time, on January 9, 2008, unless we determine, in our sole discretion, to extend the exchange offer, in which case it will expire at the later date and time to which it is extended. We do not currently intend to extend the exchange offer, although we reserve the right to do so. If we extend the exchange offer, we will give oral or written notice of the extension to the exchange agent and give each registered holder notice by means of a press release or other public announcement of any extension prior to 9:00 a.m., New York City time, on the next business day after the scheduled expiration date. If we amend the exchange offer in a manner which we consider to constitute a material change, we will promptly disclose such amendment by means of a prospectus supplement that we will distribute to each registered holder of old notes.

We also reserve the right, in our sole discretion,

•: to delay accepting any old notes or, if any of the conditions set forth below under "—Conditions" have not been satisfied or waived, to terminate the exchange offer by giving oral or written notice of such delay or termination to the exchange agent, or
•: to amend the terms of the exchange offer in any manner by complying with Rule 14e-l(d) under the Exchange Act to the extent that rule applies.

We acknowledge and undertake to comply with the provisions of Rule 14e-l(c) under the Exchange Act, which requires us to pay the consideration offered, or return the old notes surrendered for exchange, promptly after the termination or withdrawal of the exchange offer. We will notify you as promptly as we can of any extension, termination or amendment.

PROCEDURES FOR TENDERING

Book-Entry Interests

The old notes were issued as global securities in fully registered form without interest coupons. Beneficial interests in the global securities, held by direct or indirect participants in DTC, are shown on, and transfers of these interests are effected only through, records maintained in book-entry form by DTC with respect to its participants.

If you hold your old notes in the form of book-entry interests and you wish to tender your old notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the expiration date either:

•: a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other documents required by such letter of transmittal, to the Exchange Agent at the address set forth on the cover page of the letter of transmittal; or
•: a computer-generated message transmitted by means of DTC's Automated Tender Offer Program system and received by the exchange agent and forming a part of a confirmation of book-entry transfer, in which you acknowledge and agree to be bound by the terms of the letter of transmittal.

In addition, in order to deliver old notes held in the form of book-entry interests:

•: a timely confirmation of book-entry transfer of such notes into the exchange agent's account at DTC pursuant to the procedure for book-entry transfers described below under "—Book-Entry Transfer" must be received by the Exchange Agent prior to the expiration date; or
•: you must comply with the guaranteed delivery procedures described below.

The method of delivery of old notes and the letter of transmittal and all other required documents to the exchange agent is at your election and risk. Instead of delivery by mail, we recommend that you use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure delivery to the exchange agent before the expiration date. You should not send the letter of transmittal or old notes to us.

You may request your broker, dealer, commercial bank, trust company, or nominee to effect the above transactions for you.

Certificated Old Notes

Only registered holders of certificated old notes may tender those notes in the exchange offer. If your old notes are certificated notes and you wish to tender those notes for exchange pursuant to the exchange offer, you must transmit to the exchange agent on or prior to the expiration date, a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other required documents, to the address set forth below under "Exchange Agent." In addition, in order to validly tender your certificated old notes:

•: the certificates representing your old notes must be received by the exchange agent prior to the expiration date; or
•: you must comply with the guaranteed delivery procedures described below.

Procedures Applicable to All Holders

If you tender an old note and you do not withdraw the tender prior to the expiration date, you will have made an agreement with us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal.

If your old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your notes, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either make appropriate arrangements to register ownership of the old notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Signatures on a letter of transmittal or a notice of withdrawal must be guaranteed by an eligible institution unless:

•: old notes tendered in the exchange offer are tendered either
•: by a registered holder who has not completed the box entitled "Special Registration Instructions" or "Special Delivery Instructions" on the letter of transmittal or
•: for the account of an eligible institution; and
•: the box entitled "Special Registration Instructions" on the letter of transmittal has not been completed.

If signatures on a letter of transmittal or a notice of withdrawal are required to be guaranteed, the guarantee must be by a financial institution, which includes most banks, savings and loan associations and brokerage houses, that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Program or the Stock Exchanges Medallion Program.

If the letter of transmittal is signed by a person other than you, your old notes must be endorsed or accompanied by a properly completed bond power and signed by you as your name appears on those old notes.

If the letter of transmittal or any old notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations, or others acting in a fiduciary or representative capacity, those persons should so indicate when signing. Unless we waive this requirement, in this instance you must submit with the letter of transmittal proper evidence satisfactory to us of their authority to act on your behalf.

We will determine, in our sole discretion, all questions regarding the validity, form, eligibility, including time of receipt, acceptance and withdrawal of tendered old notes. This determination will be final and binding. We reserve the absolute right to reject any and all old notes not properly tendered or any old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties.

You must cure any defects or irregularities in connection with tenders of your old notes within the time period we will determine unless we waive that defect or irregularity. Although we intend to notify you of defects or irregularities with respect to your tender of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give this notification. Your tender will not be deemed to have been made and your notes will be returned to you if:

•: you improperly tender your old notes;
•: you have not cured any defects or irregularities in your tender; and
•: we have not waived those defects, irregularities or improper tender.

In this event, the Exchange Agent will return your notes, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration of the exchange offer.

In addition, we reserve the right in our sole discretion to:

•: purchase or make offers for, or offer Exchange Notes for, any old notes that remain outstanding subsequent to the expiration of the exchange offer;
•: terminate the exchange offer; and
•: to the extent permitted by applicable law, purchase notes in the open market, in privately negotiated transactions or otherwise.

The terms of any of these purchases or offers could differ from the terms of the exchange offer.

By tendering, you will represent to us that, among other things:

•: the Exchange Notes to be acquired by you in the exchange offer are being acquired in the ordinary course of your business;
•: you are not engaging in and do not intend to engage in a distribution of the Exchange Notes to be acquired by you in the exchange offer;
•: you do not have an arrangement or understanding with any person to participate in the distribution of the Exchange Notes to be acquired by you in the exchange offer; and
•: you are not our "affiliate," as defined under Rule 405 of the Securities Act.

In all cases, issuance of Exchange Notes for old notes that are accepted for exchange in the exchange offer will be made only after timely receipt by the Exchange Agent of certificates for your old notes or a timely book-entry confirmation of your old notes into the exchange agent's account at DTC, a properly completed and duly executed letter of transmittal, or a computer-generated message instead of the letter of transmittal, and all other required documents. If any tendered old notes are not accepted for any reason set forth in the terms and conditions of the exchange offer or if old notes are submitted for a greater principal amount than you desire to exchange, the unaccepted or non-exchanged old notes, or old notes in substitution therefor, will be returned without expense to you. In addition, in the case of old notes tendered by book-entry transfer into the exchange agent's account at DTC pursuant to the book-entry transfer procedures described below, the non-exchanged old notes will be credited to your account maintained with DTC, as promptly as practicable after the expiration or termination of the exchange offer.

The Exchange Agent will establish an account with respect to the book-entry interests at DTC for purposes of the exchange offer promptly after the date of this prospectus. You must deliver your book-entry interest by book-entry transfer to the account maintained by the exchange agent at DTC. Any financial institution that is a participant in DTC's systems may make book-entry delivery of book-entry interests by causing DTC to transfer the book-entry interests into the exchange agent's account at DTC in accordance with DTC's procedures for transfer.

If one of the following situations occur:

•: you cannot deliver a book-entry confirmation of book-entry delivery of your book-entry interests into the exchange agent's account at DTC; or
•: you cannot deliver all other documents required by the letter of transmittal to the exchange agent prior to the expiration date,

then you must tender your book-entry interests according to the guaranteed delivery procedures discussed above.

Guaranteed Delivery Procedures

If you desire to tender your old notes and your old notes are not immediately available or one of the situations described in the immediately preceding paragraph occurs, you may tender if:

•: you tender through an eligible financial institution;
•: on or prior to 5:00 p.m., New York City time, on the expiration date, the exchange agent receives from an eligible institution, a written or facsimile copy of a properly completed and duly executed letter of transmittal and notice of guaranteed delivery, substantially in the form provided by us; and
•: the certificates for all certificated old notes, in proper form for transfer, or a book-entry confirmation, and all other documents required by the letter of transmittal, are received by the exchange agent within three New York Stock Exchange trading days after the date of execution of the notice of guaranteed delivery.

The notice of guaranteed delivery may be sent by facsimile transmission, mail or hand delivery. The notice of guaranteed delivery must set forth:

•: your name and address;
•: the amount of old notes you are tendering; and
•: a statement that your tender is being made by the notice of guaranteed delivery and that you guarantee that within three New York Stock Exchange trading days after the execution of the notice of guaranteed delivery, the eligible institution will deliver the following documents to the exchange agent:
•: the certificates for all certificated old notes being tendered, in proper form for transfer or a book-entry confirmation of tender;
•: a written or facsimile copy of the letter of transmittal, or a book-entry confirmation instead of the letter of transmittal; and
•: any other documents required by the letter of transmittal.

The Exchange Agent will establish an account with respect to the book-entry interests at DTC for purposes of the exchange offer promptly after the date of this prospectus. You must deliver your book-entry interest by book-entry transfer to the account maintained by the Exchange Agent at DTC. Any financial institution that is a participant in DTC's systems may make book-entry delivery of book-entry interests by causing DTC to transfer the book-entry interests into the Exchange Agent's account at DTC in accordance with DTC's procedures for transfer.

If one of the following situations occur:

•: you cannot deliver a book-entry confirmation of book-entry delivery of your book-entry interests into the Exchange Agent's account at DTC; or
•: you cannot deliver all other documents required by the letter of transmittal to the Exchange Agent prior to the expiration date,
•: then you must tender your book-entry interests according to the guaranteed delivery procedures discussed above.

Withdrawal Rights

You may withdraw tenders of your old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

For your withdrawal to be effective, the Exchange Agent must receive a written or facsimile transmission notice of withdrawal at its address set forth below under "—Exchange Agent" prior to 5:00 p.m., New York City time, on the expiration date.

The notice of withdrawal must:

•: state your name;
•: identify the specific old notes to be withdrawn, including the certificate number or numbers and the principal amount of withdrawn notes;
•: be signed by you in the same manner as you signed the letter of transmittal when you tendered your old notes, including any required signature guarantees or be accompanied by documents of transfer sufficient for the exchange agent to register the transfer of the old notes into your name; and
•: specify the name in which the old notes are to be registered, if different from yours.

We will determine all questions regarding the validity, form and eligibility, including time of receipt, of withdrawal notices. Our determination will be final and binding on all parties. Any old notes withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any old notes which have been tendered for exchange but which are not exchanged for any reason will be returned to you without cost as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old notes may be retendered by following one of the procedures described under "—Procedures for Tendering" above at any time on or prior to 5:00 p.m., New York City time, on the expiration date.

Certain Conditions to the Exchange Offer

Notwithstanding any other provision of the exchange offer and subject to our obligations under the Registration Rights Agreement, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any old notes and may terminate or amend the exchange offer, if at any time before the acceptance of any old notes for exchange any of the following events occur:

•: any injunction, order or decree has been issued by any court or any governmental agency that would prohibit, prevent or otherwise materially impair our ability to proceed with the exchange offer; or
•: the exchange offer violates any applicable law or any applicable interpretation of the staff of the Commission.

These conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to them, subject to applicable law. We also may waive in whole or in part at any time and from time to time any particular condition in our sole discretion. If we waive a condition, we may be required in order to comply with applicable securities laws to extend the expiration date of the exchange offer. Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of these rights and these rights will be deemed ongoing rights which may be asserted at any time and from time to time.

In addition, we will not accept for exchange any old notes tendered, and no Exchange Notes will be issued in exchange for any of those old notes, if at the time the old notes are tendered any stop order is threatened by the Commission or in effect with respect to the registration statement of which this prospectus is a part or the qualification of the indenture under the Trust Indenture Act of 1939.

The exchange offer is not conditioned on any minimum principal amount of old notes being tendered for exchange.

Accounting Treatment

We will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offer. We will amortize the expense of the exchange offer over the term of the Exchange Notes under United States generally accepted accounting principles.

DESCRIPTION OF THE EXCHANGE NOTES

The $500,000,000 principal amount of our old notes, which we are offering to exchange for $500,000,000 principal amount of our Exchange Notes, were issued under an original indenture dated as of April 3, 2007, among Steel Dynamics, Inc., as issuer, the Subsidiary Guarantors, as guarantors, and The Bank of New York Trust Company, N.A., as Trustee The original indenture has since then been amended to add additional Subsidiary Guarantors. The original indenture, as so amended, is referred to hereafter as the "Indenture."

The terms of the Exchange Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939.

Any old notes that remain outstanding after the consummation of the exchange offer and the issuance of the Exchange Notes will be treated as a single class under the Indenture, including for purposes of determining whether the required percentage of noteholders have given their approval or consent to an amendment or waiver or joined in directing the Trustee to take certain actions on behalf of all noteholders.

Certain terms used in this description are defined herein under the subheading "Definitions." For purposes of this "Description of the Exchange Notes," the term "Steel Dynamics" refers only to Steel Dynamics, Inc., and not to any of its subsidiaries.

The following is a summary of the material provisions of the Indenture but does not restate the Indenture in its entirety. You can find the definitions of certain capitalized terms used in the following summary under the subheading "Definitions" in the Indenture. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the Notes. A copy of the Indenture, as amended, is available upon request from Steel Dynamics or may be viewed by reference to the exhibits incorporated by reference into the registration statement of which this prospectus is a part, which may in turn be accessed through our filings with the Securities and Exchange Commission, at www.sec.gov. For purposes of this "Description of the Notes," the term "Steel Dynamics" means Steel Dynamics, Inc. and its successors under the Indenture, in each case excluding its subsidiaries.

General

The Exchange Notes will be unsecured unsubordinated obligations of Steel Dynamics, limited to $500 million aggregate principal amount, and will mature on April 1, 2015. Steel Dynamics, without the consent of the holders of the Exchange Notes, may issue additional notes ("Additional Notes") under the Indenture. None of these Additional Notes may be issued if an Event of Default (as defined under the heading "—Events of Default") has occurred and is continuing with respect to the Exchange Notes. The old notes, any Exchange Notes issued as described under the subheading "—Registration Rights," and any Additional Notes subsequently issued would be treated as a single class for all purposes under the Indenture.

Each Exchange Note will bear interest at the rate of 6³/4% per annum from the most recent interest payment date to which interest has been paid. Interest on the Exchange Notes will be payable semiannually on April 1 and October 1 of each year, commencing October 1, 2007. Interest will be paid to Holders of record at the close of business on the March 15 or September 15 immediately preceding the interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months on a U.S. corporate bond basis.

If by the date that is nine months after the Closing Date of April 3, 2007, Steel Dynamics has not consummated a registered exchange offer for the Notes or caused a shelf registration statement with respect to resales of the Notes to be declared effective, the annual interest rate on the Notes will increase by .5% until the consummation of a registered exchange offer or the effectiveness of a shelf registration statement. See "—Registration Rights" hereunder.

The Notes may be exchanged or transferred at the office or agency of Steel Dynamics in The Borough of Manhattan, The City of New York. Initially, the corporate trust office of the Trustee in New York, New York will serve as such office.

The Exchange Notes will be issued only in fully registered form, without coupons, in denominations of $2,000 of principal amount and multiples of $1,000 in excess thereof. See "—Book-Entry; Delivery and Form." No service charge will be made for any registration of transfer or exchange of the Exchange Notes, but Steel Dynamics may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection therewith.

Repurchase of Notes upon a Change of Control

Steel Dynamics must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Exchange Notes then outstanding, at a purchase price equal to 101% of their principal amount, plus accrued interest, if any, to the Payment Date.

There can be no assurance that Steel Dynamics will have sufficient funds available at the time of any Change of Control to make any debt payment (including repurchases of Exchange Notes) required by the foregoing covenant, as well as any other repayments pursuant to covenants that may be contained in other securities of Steel Dynamics which might be outstanding at the time.

The above described covenant requiring Steel Dynamics to repurchase the Exchange Notes will, unless consents are obtained, require Steel Dynamics to repay all indebtedness then outstanding which by its terms would prohibit such Exchange Note repurchase, either prior to or concurrently with such Exchange Note repurchase.

Steel Dynamics will not be required to make an Offer to Purchase upon the occurrence of a Change of Control, if a third party makes an offer to purchase the Exchange Notes in the manner, at the times and price and otherwise in compliance with the requirements of the Indenture applicable to an Offer to Purchase for a Change of Control and purchases all Exchange Notes validly tendered and not withdrawn in such offer to purchase.

Optional Redemption

Steel Dynamics may redeem the Exchange Notes at any time on or after April 1, 2011. The redemption price for the Exchange Notes (expressed as a percentage of principal amount), will be as set forth below, plus accrued interest to the redemption date, if redeemed during the twelve-month period commencing on April 1 of the years indicated below:

Year	Redemption Price
2011	103.375	%
2012	101.688	%
2012 and thereafter	100.000	%

In addition, at any time prior to April 1, 2010, Steel Dynamics may redeem up to 35% of the principal amount of the Exchange Notes with the net cash proceeds of one or more sales of its Common Stock at a redemption price (expressed as a percentage of principal amount) of 106.750%, plus accrued interest to the redemption date; provided that at least 65% of the aggregate principal amount of the Exchange Notes originally issued on the Closing Date remains outstanding after each such redemption and notice of any such redemption is mailed within 60 days of each such sale of Common Stock.

Steel Dynamics will give not less than 30 days' nor more than 60 days' notice of any redemption. If less than all of the Exchange Notes are to be redeemed, selection of the Exchange Notes for redemption will be made by the Trustee:

•: in compliance with the requirements of the principal national securities exchange, if any, on which the Exchange Notes are listed, or,
•: if the Exchange Notes are not listed on a national securities exchange, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate.

However, no Exchange Note of $1,000 in principal amount or less shall be redeemed in part. If any Exchange Note is to be redeemed in part only, the notice of redemption relating to such Exchange Note will state the portion of the principal amount to be redeemed. A new Exchange Note in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Exchange Note.

Guarantees

Payment of the principal of, premium, if any, and interest on the Exchange Notes will be Guaranteed, jointly and severally, on an unsecured unsubordinated basis by the Initial Subsidiary Guarantors and any additional Subsidiary Guarantors which become Subsidiary Guarantors pursuant to a supplemental indenture. The indenture provides that each Significant Subsidiary of Steel Dynamics (other than a Foreign Subsidiary) that (a) Guarantees Indebtedness of Steel Dynamics or any Subsidiary Guarantor in an aggregate amount in excess of $50 million or (b) incurs or otherwise becomes liable for Indebtedness or Attributable Debt in respect of Sale and Leaseback Transactions, in an aggregate amount in excess of $50 million (other than (x) Indebtedness secured by a Mortgage permitted by clause (1), (2), (3), (4) or (5) of the "Limitation on Liens" covenant or unsecured Indebtedness incurred to provide funds for the cost of acquisition, construction, development or improvement of property of such Significant Subsidiary and (y) Attributable Debt permitted by clauses (1) through (4) of the "Limitation on Sale and Leaseback Transactions" covenant), will Guarantee payment of the principal of, premium if any and interest on the Notes. Except as described herein, Steel Dynamics' Unrestricted Subsidiaries will not Guarantee the Notes.

The obligations of a Subsidiary Guarantor under its Exchange Note Guarantee will be limited so as not to constitute a fraudulent conveyance or fraudulent transfer under applicable Federal or state laws. A Subsidiary Guarantor that makes a payment or distribution under its Exchange Note Guarantee will be entitled to contribution from any other Subsidiary Guarantor.

The Exchange Note Guarantee issued by any Subsidiary Guarantor will be automatically and unconditionally released and discharged upon

(1) any sale, exchange or transfer to any Person (other than an Affiliate of Steel Dynamics) of all of the Capital Stock of such Subsidiary Guarantor,

(2) the release or discharge of the guarantee by such Subsidiary Guarantor of Indebtedness of Steel Dynamics or the repayment of the Indebtedness (or Attributable Debt) of such Subsidiary Guarantor, in each case which resulted in the obligation to Guarantee the Notes;provided that such Subsidiary Guarantor has not Guaranteed any other Indebtedness of Steel Dynamics or incurred or otherwise become liable for any other Indebtedness (or Attributable Debt) which would have resulted in an obligation to Guarantee the Notes;

(3) if the Notes are rated Investment Grade by both Rating Agencies and no Default or Event of Default shall have occurred and then be continuing; or

(4) if the Notes are defeased in accordance with the terms of the Indenture.

We are not restricted from selling or otherwise disposing of any of the Subsidiary Guarantors or any or all of the assets of any of the Subsidiary Guarantors.

Ranking

The Exchange Notes will be equal in right of payment with all existing and future unsubordinated unsecured indebtedness of Steel Dynamics and senior in right of payment to all subordinated indebtedness of Steel Dynamics, including Steel Dynamics' 4% Convertible Subordinated Notes due 2012. The Exchange Note Guarantees will be equal in right of payment with all existing and future unsubordinated unsecured indebtedness of the Subsidiary Guarantors and senior in right of payment to all subordinated indebtedness of the Subsidiary Guarantors. The Notes and the Note Guarantees will be effectively subordinated to any secured Indebtedness to the extent of the value of the assets securing such debt. The Credit Agreement is secured by the inventory and accounts, chattel paper, instruments, deposit accounts, letter of credit rights and general intangibles of Steel Dynamics and its subsidiaries that have guaranteed the Credit Agreement. The Credit Agreement is also secured by a pledge of the capital stock or other equity interests of Steel Dynamics and its subsidiaries that have guaranteed the Credit Agreement.

As of December 31, 2006, after giving effect to the $500 million of old notes and the use of proceeds therefrom, we would have had $555.1 million of consolidated Indebtedness outstanding, of which there would have been (i) $17.6 million of secured indebtedness outstanding (and the ability to borrow up to $350.0 million of additional secured indebtedness under our Credit Agreement) and (ii) $37.5 million of subordinated indebtedness outstanding.

As of September 30, 2007, however, after giving effect to the issuance and sale of $700 million of our 7³/8% Senior Notes due 2012 and the application of the net proceeds therefrom to finance the acquisition of OmniSource Corporation on October 26, 2007 and to repay certain outstanding amounts under our senior secured credit agreement, we would have had $1.8 billion of consolidated indebtedness outstanding, which there would have been:

•: $615.7 million of secured indebtedness;
•: $37.3 million of subordinated indebtedness;
•: $500.0 million of unsecured 6³/4% Senior Notes due 2015; and
•: $700.0 million of unsecured 7³/8% Senior Notes due 2012.

The Notes will be effectively subordinated to all of the liabilities of the subsidiaries of Steel Dynamics that do not guarantee the Notes. As of September 30, 2007, these non-guarantor subsidiaries had $30.6 million of liabilities outstanding, including $ 13.4 million of indebtedness, all of which indebtedness is held by Steel Dynamics. See the footnote captioned "Condensed Consolidating Information" to our annual financial statements incorporated by reference herein for selected financial information regarding us, the subsidiary guarantors and the non-guarantor subsidiaries.

Sinking Fund

There will be no sinking fund payments for the Exchange Notes.

Registration Rights

The following is a summary of the material provisions of the Registration Rights Agreement. You should read the proposed form of the Registration Rights Agreement. A copy of the form of Registration Rights Agreement is available from Steel Dynamics upon request.

Steel Dynamics and the Initial and Additional Subsidiary Guarantors have agreed with the initial purchasers, for the benefit of the Holders, that they will use their reasonable best efforts, at their cost, to file and cause to become effective a registration statement with respect to a registered offer (the "Exchange Offer") to exchange the old notes for an issue of unsubordinated Exchange Notes of Steel Dynamics, guaranteed by the Subsidiary Guarantors, with terms identical to the old notes (except that the Exchange Notes will not bear legends restricting transfer).

The Exchange Offer will remain open for not less than 20 business days after the date Steel Dynamics mails notice of the Exchange Offer to Holders, as defined herein and in the Registration Rights Agreement. For each old note surrendered to Steel Dynamics under the Exchange Offer, the Holder will receive an Exchange Note of equal principal amount. Interest on each Exchange Note shall accrue from the last interest payment date on which interest was paid on the old notes so surrendered or, if no interest has been paid on such old notes, from the Closing Date.

If Steel Dynamics effects the Exchange Offer, it will be entitled to close the Exchange Offer 20 business days after the commencement thereof, provided that it has accepted all old notes validly surrendered in accordance with the terms of the Exchange Offer. Old notes not tendered in the Exchange Offer will bear interest at the rate set forth on the cover page of this prospectus and be subject to all of the terms and conditions specified in the Indenture and to the transfer restrictions described in "Transfer Restrictions."

In the event that applicable interpretations of the staff of the Securities and Exchange Commission do not permit Steel Dynamics to effect the Exchange Offer, or under other specified circumstances, Steel Dynamics and the Subsidiary Guarantors will, at their cost, use their best efforts to cause to become effective a shelf registration statement (the "Shelf Registration Statement") with respect to resale of the old notes. Steel Dynamics and the Subsidiary Guarantors will use their best efforts to keep such Shelf Registration Statement effective until the expiration of the time period referred to in Rule 144(k) under the Securities Act after the Closing Date, or such shorter period that will terminate when all old notes covered by a Shelf Registration Statement have been sold pursuant to a Shelf Registration Statement. Steel Dynamics and the Subsidiary Guarantors will, in the event of such a shelf registration, provide to each Holder copies of the prospectus, notify each Holder when the Shelf Registration Statement for the old notes has become effective and take certain other actions as are required to permit resale of the old notes. A Holder that sells its old notes pursuant to the Shelf Registration Statement (1) generally will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, (2) will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and (3) will be bound by the provisions of the Registration Rights Agreement that are applicable to such a Holder (including certain indemnification obligations).

In the event that the Exchange Offer is not consummated on or prior to the date that is nine months after the Closing Date, the annual interest rate borne by the Notes will be increased by .5% over the rate shown on the cover page of this prospectus. Once the Exchange Offer is consummated or the Shelf Registration Statement is declared effective, the annual interest rate borne by the old notes shall be changed to again be the rate shown on the cover page of this prospectus.

Certain Covenants

Limitation on Liens

Steel Dynamics will not, and will not permit any of its Significant Subsidiaries to, create, incur, issue, assume or guarantee any Indebtedness secured by a Mortgage upon any of its properties or assets, whether owned on the Closing Date or thereafter acquired, without effectively providing concurrently that the Notes are secured equally and ratably with or, at our option, prior to such Indebtedness so long as such Indebtedness shall be so secured.

Notwithstanding the restrictions described above, Steel Dynamics and any of its Significant Subsidiaries may create, incur, issue, assume or guarantee Indebtedness secured by Mortgages without equally and ratably securing the Notes, if at the time of such creation, incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Indebtedness which is concurrently being retired, the aggregate amount of all such Indebtedness secured by Mortgages which would otherwise be subject to such restrictions (other than any Indebtedness secured by Mortgages permitted as described in clauses (1) through (8) of the immediately preceding paragraph) plus all Attributable Debt of Steel Dynamics and any of its Significant Subsidiaries in respect of Sale and Leaseback Transactions (with the exception of such transactions which are permitted under clauses (1) through (4) of the first sentence of the first paragraph under "—Limitation on Sale and Leaseback Transactions" below) does not exceed 10% of Consolidated Tangible Assets.

If an Event of Default (other than an Event of Default specified in clause (f) or (g) above that occurs with respect to Steel Dynamics or any Subsidiary Guarantor) occurs and is continuing under the Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to Steel Dynamics (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest shall be immediately due and payable. In the event of a declaration of acceleration because an Event of Default set forth in clause (d) above has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (d) shall be remedied or cured by Steel Dynamics, the relevant Subsidiary Guarantor or the relevant Significant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto. If an Event of Default specified in clause (f) or (g) above occurs with respect to Steel Dynamics or any Subsidiary Guarantor, the principal of, premium, if any, and accrued interest on the Notes then outstanding shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of at least a majority in principal amount of the outstanding Notes by written notice to Steel Dynamics and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if (x) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (y) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. For information as to the waiver of defaults, see "—Modification and Waiver."

The Holders of at least a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes. A Holder may not pursue any remedy with respect to the Indenture or the Notes unless:

(1): the Holder gives the Trustee written notice of a continuing Event of Default;
(2): the Holders of at least 25% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy;
(3): such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense;
(4): the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and
(5): during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request.

However, such limitations do not apply to the right of any Holder of a Note to receive payment of the principal of, premium, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, which right shall not be impaired or affected without the consent of the Holder.

An officer of Steel Dynamics must certify, on or before a date not more than 90 days after the end of each fiscal year, that a review has been conducted of the activities of Steel Dynamics and its Subsidiaries and Steel Dynamics' and its Subsidiaries' performance under the Indenture and that Steel Dynamics has fulfilled all obligations thereunder, or, if there has been a default in the fulfillment of any such obligation, specifying each such default and the nature and status thereof. Steel Dynamics will also be obligated to notify the Trustee of any default or defaults in the performance of any covenants or agreements under the Indenture.

No Personal Liability of Incorporators, Stockholders, Officers, Directors or Employees

No recourse for the payment of the principal of, premium, if any, or interest on any of the Exchange Notes or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of Steel Dynamics in the Indenture, or in any of the Exchange Notes or because of the creation of any Indebtedness represented thereby, shall be had against any incorporator, stockholder, officer, director, employee or controlling person of Steel Dynamics or of any successor Person thereof. Each Holder, by accepting the Exchange Notes, waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Exchange Notes. Such waiver may not be effective to waive liabilities under the federal securities laws.

Concerning the Trustee

Except during the continuance of a Default, the Trustee will not be liable, except for the performance of such duties as are specifically set forth in the Indenture. If an Event of Default has occurred and is continuing, the Trustee will use the same degree of care and skill in its exercise of the rights and powers vested in it under the Indenture as a prudent person would exercise under the circumstances in the conduct of such person's own affairs.

The Indenture and provisions of the Trust Indenture Act of 1939, as amended, incorporated by reference therein contain limitations on the rights of the Trustee, should it become a creditor of Steel Dynamics, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The Trustee is permitted to engage in other transactions; provided, however, that if it acquires any conflicting interest, it must eliminate such conflict or resign.

Book-Entry; Delivery and Form

The old notes were offered and sold to qualified institutional buyers in reliance on Rule 144A ("Rule 144A Notes"). Notes also were offered and sold in offshore transactions in reliance on Regulation S ("Regulation S Notes"). Except as set forth below, Notes have been issued in registered, global form in minimum initial denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Rule 144A Notes initially were represented by one or more notes in registered, global form without interest coupons (collectively, the "Rule 144A Global Notes"). Regulation S Notes initially were represented by one or more Notes in registered, global form without interest coupons (collectively, the "Regulation S Global Notes" and, together with the Rule 144A Global Notes, the "Global Notes"). The Global Notes were deposited upon issuance with the Trustee as custodian for

The Depository Trust Company ("DTC"), and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below.

The Exchange Notes will also be issued in the form of one or more Global Notes registered in the name of the DTC or its nominee.

Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may be exchanged for Notes in certificated form. See "—Exchange of Book-Entry Notes for Certificated Notes." Rule 144A Notes (including beneficial interests in the Rule 144A Global Notes) are subject to certain restrictions on transfer and bear a restrictive legend as described under "Notice to Investors."

Exchange of Global Notes for Certificated Notes

A Global Note is exchangeable for definitive Notes in registered certificated form, or Certificated Notes, if:

(1): DTC (a) notifies Steel Dynamics that it is unwilling or unable to continue as depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act, and in each case Steel Dynamics fails to appoint a successor depositary; or
(2): Steel Dynamics, at its option, notifies the Trustee in writing that it elects to cause the issuance of Certificated Notes.

Additionally, Exchange Notes transferred to Non-Global Purchasers will be in registered form without interest coupons, as Certificated Notes. Upon the transfer of Certificated Notes initially issued to a Non-Global Purchaser to a qualified institutional buyer or in accordance with Regulation S, such Certificated Notes will, unless the relevant Global Note has previously been exchanged in whole for Certificated Notes, be exchanged for an interest in a Global Note.

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures) and will bear the applicable restrictive legend referred to in "Notice to Investors," unless that legend is not required by applicable law and Steel Dynamics and the Trustee receive evidence thereof satisfactory to them.

Exchanges Between Regulation S Notes and Rule 144A Notes

Beneficial interests in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in the Indenture) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available). If such transfer occurs prior to the expiration of the Restricted Period, the interest transferred will be held immediately thereafter through Euroclear or Clearstream.

Transfers involving exchanges of beneficial interests between the Regulation S Global Notes and the Rule 144A Global Notes will be effected in DTC by means of an instruction originated by the Trustee through the DTC Deposit/Withdraw at Custodian system. Accordingly, in connection with any such transfer, appropriate adjustments will be made to reflect a decrease in the principal amount of the Regulation S Global Note and a corresponding increase in the principal amount of the Rule 144A Global Note or vice versa, as applicable. Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in the other Global Note will, upon transfer, cease to be an interest in such Global Note and will become an interest in the other

Global Note and, accordingly, will thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interest in such other Global Note for so long as it remains such an interest. The policies and practices of DTC may prohibit transfers of beneficial interests in the Regulation S Global Note prior to the expiration of the Restricted Period.

Defeasance

Defeasance and Discharge. The Indenture provides that Steel Dynamics will be deemed to have paid and will be discharged from any and all obligations in respect of the Exchange Notes on the 123^rd day after the deposit referred to below, and the provisions of the Indenture will no longer be in effect with respect to the Exchange Notes (except for, among other matters, certain obligations to register the transfer or exchange of the Exchange Notes, to replace stolen, lost or mutilated Exchange Notes, to maintain paying agencies and to hold monies for payment in trust) if, among other things:

(A): Steel Dynamics has deposited with the Trustee, in trust, money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued interest on the Exchange Notes (i) on the Stated Maturity of such payments in accordance with the terms of the Indenture and the Exchange Notes or (ii) on any earlier Redemption Date pursuant to the terms of the Indenture and the Exchange Notes; provided that Steel Dynamics has provided the Trustee with irrevocable instructions to redeem all of the outstanding Exchange Notes on such Redemption Date,
(B): Steel Dynamics has delivered to the Trustee (1) either (x) an Opinion of Counsel to the effect that Holders will not recognize income, gain or loss for federal income tax purposes as a result of Steel Dynamics' exercise of its option under this "Defeasance" provision 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, defeasance and discharge had not occurred, which Opinion of Counsel must be based upon (and accompanied by a copy of) a ruling of the Internal Revenue Service to the same effect unless there has been a change in applicable federal income tax law after the Closing Date such that a ruling is no longer required or (y) a ruling directed to the Trustee received from the Internal Revenue Service to the same effect as the aforementioned Opinion of Counsel and (2) an Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section547 of the United States Bankruptcy Code or Section15 of the New York Debtor and Creditor Law,
(C): immediately after giving effect to such deposit on a pro forma basis, no Event of Default, or event that after the giving of notice or lapse of time or both would become an Event of Default, shall have occurred and be continuing on the date of such deposit or during the period ending on the 123^rd day after the date of such deposit, and such deposit shall not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which Steel Dynamics or any of its Subsidiaries is a party or by which Steel Dynamics or any of its Subsidiaries is bound and
(D): if at such time the Exchange Notes are listed on a national securities exchange, Steel Dynamics has delivered to the Trustee an Opinion of Counsel to the effect that the Exchange Notes will not be delisted as a result of such deposit, defeasance and discharge.

Defeasance of Certain Covenants and Certain Events of Default. The Indenture further provides that the provisions of the Indenture will no longer be in effect with respect to the provisions of the Indenture described under the heading "Repurchase of Notes Upon a Change of Control" and all the covenants described herein under "Covenants," clause (c) under "Events of Default," and clauses

(d) and (e) under "Events of Default" shall be deemed not to be Events of Default upon, among other things, the deposit with the Trustee, in trust, of money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued interest on the Exchange Notes (i) on the Stated Maturity of such payments in accordance with the terms of the Indenture and the Exchange Notes or (ii) on any earlier Redemption Date pursuant to the terms of the Indenture and the Exchange Notes; provided that Steel Dynamics has provided the Trustee with irrevocable instructions to redeem all of the outstanding Exchange Notes on such Redemption Date, the satisfaction of the provisions described in clauses (B)(2), (C) and (D) of the preceding paragraph and the delivery by Steel Dynamics to the Trustee of an Opinion of Counsel to the effect that, among other things, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance of certain covenants and Events of Default 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.

Defeasance and Certain Other Events of Default. In the event Steel Dynamics exercises its option to omit compliance with certain covenants and provisions of the Indenture with respect to the Exchange Notes as described in the immediately preceding paragraph and the Exchange Notes are declared due and payable because of the occurrence of an Event of Default that remains applicable, the amount of money and/or U.S. Government Obligations on deposit with the Trustee will be sufficient to pay amounts due on the Exchange Notes at the time of their Stated Maturity but may not be sufficient to pay amounts due on the Exchange Notes at the time of the acceleration resulting from such Event of Default. However, Steel Dynamics will remain liable for such payments and any Subsidiary Guarantor's Exchange Note Guarantee with respect to such payments will remain in effect.

Modification and Waiver

The Indenture may be amended, without the consent of any Holder, to:

(1): cure any ambiguity, defect or inconsistency in the Indenture;
(2): comply with the provisions described under "Consolidation, Merger and Sale of Assets";
(3): comply with any requirements of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act or in order to maintain such qualification;
(4): evidence and provide for the acceptance of appointment by a successor Trustee;
(5): provide for the issuance of Additional Notes; or
(6): make any change that, in the good faith opinion of the Board of Directors, does not materially and adversely affect the rights of any Holder.

Modifications and amendments of the Indenture may be made by Steel Dynamics and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Exchange Notes; provided, however, that no such modification or amendment may, without the consent of each Holder affected thereby,

(1): change the Stated Maturity of the principal of, or any installment of interest on, any Exchange Note,

(7): release any Subsidiary Guarantor from its Exchange Note Guarantee, except as provided in the Indenture,

MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

The exchange of an old note for an Exchange Note pursuant to the exchange offer will not constitute a "significant modification" of the old note for U.S. federal income tax purposes and, accordingly, the Exchange Note received will be treated as a continuation of the old note in the hands of such holder. As a result, there will be no U.S. federal income tax consequences to a holder who exchanges an old note for an Exchange Note pursuant to the exchange offer and any such holder will have the same adjusted tax basis and holding period in the Exchange Note as it had in the old note immediately before the exchange. A holder who does not exchange its old notes for Exchange Notes pursuant to the exchange offer will not recognize any gain or loss, for U.S. federal income tax purposes, upon consummation of the exchange offer.

PLAN OF DISTRIBUTION

Each broker-dealer that receives Exchange Notes for its own account pursuant to this exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such 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 where such old notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

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, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of Exchange Notes and any commission or concessions received by any such 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 180 days after the expiration date we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. We have agreed to pay all expenses incident to the exchange offer, including the reasonable fees and expenses of counsel to the initial purchasers of the old notes, other than commissions or concessions of any brokers or dealers. We will indemnify the holders of the notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

The Indiana Corporations

Indiana Business Corporation Law. Chapter 37 of the Indiana Business Corporation Law ("IBCL") provides that a corporation may indemnify an individual made a party to a proceeding because the individual is or was a director against liability incurred in a proceeding if (i) the individual's conduct was in good faith, (2) the individual reasonably believed, in the case of conduct in the individual's official capacity with the corporation, that the individual's conduct was in the corporation's best interests, and, (3) in the case of a criminal proceeding, the individual either had reasonable cause to believe the individual's conduct was lawful or had no reasonable cause to believe the individual's conduct was unlawful. Unless limited by its articles of incorporation, a corporation must indemnify a director against reasonable expenses incurred by the director if the director was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was a party because the director is or was a director of the corporation. A corporation may advance or reimburse reasonable expenses incurred by a person entitled to indemnification, in advance of final disposition, if the individual furnishes the corporation with a written affirmation of his or her good faith belief that the applicable standard of conduct was observed, accompanied by a written undertaking to repay the advance if it is ultimately determined that the applicable standards were not met. Unless the director has been successful in the defense of a proceeding, a corporation may not indemnify a director unless authorized in the specific case after a determination has been made that indemnification of the director is permissible in the circumstances because the director has met the standard of conduct set forth under the law.

Officers, unless the corporation's articles of incorporation provide otherwise, may be indemnified to the same extent as directors.

A corporation may purchase and maintain insurance on behalf of an individual who is or was a director, officer, employee, or agent of the corporation, or who, while a director, officer, employee, or agent of the corporation, is or was serving at the request of the corporation as a director, officer, partner, member, manager, trustee, employee, or agent of another foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan, or other enterprise, against liability asserted against or incurred by the individual in that capacity or arising from the individual's status as a director, officer, member, manager, employee, or agent. The indemnification provided for or authorized by the IBCL does not exclude other rights to indemnification and that a person may have under a corporation's articles of incorporation, bylaws or certain other duly authorized agreements.

II-1

to the proceeding because the individual is or was a director or officer, or, at our request, was serving as a director, officer, partner, trustee, employee, or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, whether or not for profit, so long as the individual's conduct was in good faith and with the reasonable belief, in connection with the individual's "official capacity," that the conduct was in our best interests, or, in all other cases, that the conduct was at least not opposed to our best interests. In the case of any criminal proceeding, the duty to indemnify applies so long as the individual either had reasonable cause to believe that the conduct was lawful, or had no reasonable cause to believe that the conduct was unlawful. Conduct with respect to an employee benefit plan in connection with a matter the individual believed to be in the best interests of the participants in and beneficiaries of the plan is deemed conduct that satisfies the indemnification standard that the individual reasonably believed that the conduct was at least not opposed to our best interests.

We may advance or reimburse for reasonable expenses incurred by a person entitled to indemnification, in advance of final disposition, if the individual furnishes us with a written affirmation of his or her good faith belief that the applicable standard of conduct was observed, accompanied by a written undertaking to repay the advance if it is ultimately determined that the applicable standards were not met.

Unless the director has been successful in the defense of a proceeding, in all cases, whether in connection with advancement of expenses during a proceeding, or afterward, we may not grant indemnification unless authorized in the specific case after a determination has been made that indemnification is permissible under the circumstances. The determination may be made either by our board of directors, by majority vote of a quorum consisting of directors not at the time parties to the proceeding, or, if a quorum cannot be so obtained, then by majority vote of a committee duly designated by the board of directors consisting solely of two or more directors not at the time parties to the proceeding. Alternatively, the determination can be made by special legal counsel selected by the board of directors or the committee, or by the stockholders, excluding shares owned by or voted under the control of persons who are at the time parties to the proceeding. In the event that a person seeking indemnification believes that it has not been properly provided that person may apply for indemnification to the court conducting the proceeding or to another court of competent jurisdiction. In such a proceeding, a court is empowered to grant indemnification if it determines that the person is fairly and reasonably entitled to indemnification in view of all of the relevant circumstances, whether or not the person met the standard of conduct for indemnification.

We may purchase and maintain, and we do so purchase and maintain insurance on behalf of our directors, officers, employees or agents, insuring against liability arising from his or her status as a director, officer, employee, or agent, whether or not we would have the power to indemnify the individual against the same liability under Article IX. Article IX does not preclude us from providing indemnification in any other manner.

We may also purchase and maintain on behalf of a director or officer insurance against liabilities incurred in such capacities, whether or not we would have the power to indemnify him against the same liability under the statute.

New Millennium Building Systems, Inc.

Articles of Incorporation and Bylaws. Neither the Articles of Incorporation nor the Bylaws of New Millennium Building Systems, Inc. contains provisions regarding the indemnification of directors or officers.

The Virginia Limited Liability Companies

Virginia Limited Liability Company Act. Section 13.1-1009 of the Virginia Limited Liability Company Act permits a Virginia limited liability company, subject to the standards and restrictions set forth in its articles of organization or operating agreement, to indemnify and hold harmless any member, manager or other person from and against any and all claims and demands whatsoever, and to pay for or reimburse any member, manager or other person for reasonable expenses incurred by such a person who is party to a proceeding in advance of final disposition of the proceeding.

II-9

Shredded Products, LLC

Operating Agreement. The Operating Agreement of Shredded Products, LLC provides that we shall indemnify a person against expenses, judgments, settlements, penalties and fines if such person is made or threatened to be made a party to a proceeding by reason of the fact that the person was or is a manager or member of the company, so long as the manager or member acted in good faith and, when the conduct was taken in such person's official capacity, in a manner reasonably believed by such manager or member to have been in the best interest of the company. In the case of criminal action, indemnification is authorized if the member or manager had reasonable cause to believe the conduct was lawful. Unless the member or manager is successful in a proceeding on the merits, indemnification shall be made only upon a determination that indemnification is permissible because the manager or member met the applicable standard of conduct.

We may advance or reimburse reasonable expenses incurred by a person entitled to indemnification, in advance of final disposition, if the person furnishes the company with a written affirmation of his or her good faith belief that the applicable standard of conduct was observed, accompanied by a written undertaking to repay the advance if it is ultimately determined that the applicable standards were not met.

The inclusion of such indemnification provisions does not preclude the company from providing indemnification in any other manner.

John W. Hancock, Jr., LLC

Operating Agreement. The Amended and Restated Operating Agreement of John W. Hancock, Jr., LLC provides that we shall fully indemnify its member for any claim asserted against the member in the member's capacity as a managing member.

The indemnification provisions set forth in the constituent documents described above, as well as the authority vested by applicable law in our boards of directors and in the limited liability companies' controlling persons to grant indemnification beyond that which is described above, may be sufficiently broad to provide indemnification of the directors, officers and controlling persons for liabilities arising under the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the directors, officers and controlling persons pursuant to the foregoing provisions, we have 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 of expenses incurred or paid by a director, officer or controlling person 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, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by us is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

We have obtained liability insurance for the benefit of our directors, officers and controlling persons which provides coverage for losses of directors, officers and controlling persons for liabilities arising out of claims against such persons acting as our officers or directors, or for any of our subsidiaries, due to any breach of duty, neglect, error, misstatement, misleading statement, omission or act done by such directors and officers, except as prohibited by law.

Item 22. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) 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 Section10(a)(3) of the Securities Act of 1933;

(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 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;

(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.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.

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

(b) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrants are subject to Rule 430C, 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.

(c) That, for the purpose of determining liability of the registrants under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, 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 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 registrants or used or referred to by the undersigned registrants;

II-13

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or their 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

(d) For purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the 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.

(e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 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 effective date of the registration statement through the date of responding to the request.

(f) The undersigned registrant hereby undertakes 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.

(g) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.
