PRELIMINARY PROSPECTUS

                          [STEEL DYNAMICS, INC. LOGO]

                               OFFER TO EXCHANGE

                $200,000,000 OF OUR 9 1/2% SENIOR NOTES DUE 2009
                      WHICH HAVE BEEN REGISTERED UNDER THE
                             SECURITIES ACT OF 1933

                                      FOR

          $200,000,000 OF OUR OUTSTANDING 9 1/2% SENIOR NOTES DUE 2009

CUSIP No. ____________

                  The Exchange Offer will Expire at 5:00 p.m.
          New York City Time, on October [--], 2002, Unless Extended.

     We are offering to exchange $200,000,000 aggregate principal amount of our
9 1/2% Senior Notes due 2009, registered under the Securities Act of 1933, for a
like principal amount of our outstanding 9 1/2% Senior Notes due 2009, which we
issued previously without registration under the Securities Act. In this
document we refer to the outstanding notes as the "old notes" and to our new
notes as the "Exchange Notes." We sometimes refer to the old notes and the
Exchange Notes collectively as the "notes."

     The terms of the exchange are subject to the conditions described in this
prospectus.

     Consider carefully the risk factors beginning on page 6 of this prospectus.

     There is no active public trading market for the Outstanding 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 denominations of $1,000. We will pay
interest on the Exchange Notes each March 15 and September 15. The first
interest payment will be due on September 15, 2002 with interest payable from
the March 15, 2002 payment of interest on the old notes. We may redeem any of
the notes beginning on March 15, 2006 at a redemption price of 104.750% of their
principal amount, plus accrued interest. The redemption price will decline to
102.375%, plus accrued interest, after March 15, 2007 and will be 100% of their
principal amount, plus accrued interest, beginning on March 15, 2008. We may
also redeem up to 35% of the aggregate principal amount of the outstanding notes
before March 15, 2005 with net proceeds of one or more sales of our capital
stock that at a redemption price equal to 109.500% of the principal amount of
the Exchange Notes being redeemed, plus accrued interest.

     The terms of the Exchange Notes that we will issue in the exchange offer
are substantially the same as those of the outstanding old notes except that the
transfer restrictions and registration rights relating to the outstanding old
notes will no longer apply.

     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if this
prospectus is truthful or complete. 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. 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), it 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 SEPTEMBER [--], 2002

                           FORWARD LOOKING STATEMENTS

     Throughout this prospectus, 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
expressions, 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 of 1934, as
amended. 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 anticipated or
predicted:

     - cyclical changes in market supply and demand for steel; general economic
       conditions; U.S. or foreign trade policy affecting steel imports or
       exports; and governmental monetary or fiscal policy in the U.S. and other
       major international economies;

     - risks and uncertainties involving new products or new technologies, such
       as our Iron Dynamics ironmaking process, in which the product or process
       or certain critical elements thereof may not work at all, may not work as
       well as expected, or may turn out to be uneconomic even if they do work;

     - changes in the availability or cost of steel scrap, steel scrap
       substitute materials 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
       incurrence of extraordinary operating expenses;

     - actions by our domestic and foreign competitors, including the addition
       or reduction of production capacity, or 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, such as the one affecting our Columbia City, Indiana structural
       steel and rail mini-mill;

                                        2


     - pending, anticipated or unanticipated private or governmental liability
       claims or litigation, or the impact of any adverse outcome of any
       currently pending or future 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 of our projects, acquisitions,
       joint ventures or strategic alliances; and

     - the impact of governmental approvals, litigation, construction delays,
       cost overruns or technology risk upon our ability to complete, start-up
       or continue to profitably operate a project, or to operate it as
       anticipated.

     We also believe that you should read the many factors described in "Risk
Factors" immediately following the "Prospectus Summary" 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 speak only
as of the date of such statement. Comparisons of results for 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.

                                    SUMMARY

     The following is a summary of material information about our business, our
company and this exchange offer. More detailed information concerning these
matters appears elsewhere in this prospectus and the information in documents
which we incorporate by reference in this prospectus. We also refer you to the
section of this prospectus entitled "Risk Factors" for a discussion of certain
issues that should be considered in evaluating an investment in the notes.

                                 STEEL DYNAMICS

     We are one of the most profitable mini-mill steel producers in the United
States in terms of operating profit per ton. We primarily own and operate a
state-of-the-art, low-cost flat-rolled mini-mill located in Butler, Indiana. Our
Butler mini-mill began commercial production in January 1996 and was constructed
in only 14 months, representing what we believe is the shortest construction
period ever for a facility of this kind. The mini-mill currently has an annual
production capacity of 2.2 million tons. The total capital cost of our Butler
mini-mill was $630 million, which we believe is significantly less than the cost
of comparable mini-mills currently operating. Our Butler mini-mill produces a
broad range of high quality hot-rolled, cold-rolled and coated steel products,
including a large variety of high value-added and high margin specialty products
such as thinner gauge rolled products and galvanized products. We sell our
products directly to end-users, intermediate steel processors and service
centers primarily in the Midwestern United States. Our products are used in
numerous industry sectors, including the automotive, construction and commercial
industries.

     In May 2002, we announced plans to construct a low-cost, coil coating
facility at our Butler mini-mill that will further increase our range of
value-added capabilities. Subject to our receipt of applicable permits, we
anticipate starting construction of the facility within the next several months
and expect to commence coating operations in the middle of 2003. The coating
facility is currently expected to have an annual production capacity of 240,000
tons and is estimated to cost $25-$30 million.

     In May 2001, we began construction of a new state-of-the-art structural
steel and rail mini-mill in Columbia City, Indiana. Our Columbia City mini-mill
is designed to have an annual production capacity of 1.3 million tons and
produce structural steel and rails at a higher quality and lower cost than
comparable mini-mills. We expect to spend approximately $315 million to
construct this mini-mill, of which $280 million has been spent as of June 30,
2002. We believe that the initial capital construction costs of our Columbia
City mini-mill will be among the lowest in the industry for such a facility. We
commenced commercial structural steel operations in late June 2002 and have
shipped our first structural products to initial customers. We expect to ramp us
these operations through regular product introductions and be fully operational
by the end of 2002. In addition, we expect to commence commercial production of
rails during the first quarter of 2003. We constructed our structural steel
facility in less than 12 months, which we believe is the shortest construction
period ever for a facility of this kind. Our structural steel operation is
designed to produce steel products for the construction, transportation and
industrial machinery markets. Our rail manufacturing operation is designed to
produce a variety of rail products for the railroad industry.

     Through our joint venture, New Millennium Building Systems, LLC, we also
produce and sell a broad range of steel joists, girders and trusses, as well as
roof and floor decking materials for use in the construction of commercial,
industrial and institutional buildings.

     Steel Dynamics, Inc. is an Indiana corporation. Our principal executive
offices are located at 6714 Pointe Inverness Way, Suite 200, Fort Wayne, Indiana
46804, and our telephone number at that address is (260) 459-3553.

     SDI Investment Company, Ferrous Resources, LLC, STLD Holdings, Inc and
Dynamic Bar Products, LLC, each a 100% owned subsidiary, have agreed to guaranty
payment of the principal of, premium, if any, and interest on the notes, jointly
and severally with Steel Dynamics, Inc., on an unsecured unsubordinated basis.

     In this prospectus "Steel Dynamics," "the Company," "SDI," "we," "us" and
"our" refer to Steel Dynamics, Inc. and its subsidiaries, including the
guarantor, unless the context requires otherwise.

RECENT DEVELOPMENTS

    PURCHASE OF QUALITECH STEEL ASSETS IN PITTSBORO, INDIANA

     On July 29, 2002, we announced that we entered into a definitive agreement
with Qualitech Steel SBQ LLC to purchase Qualitech's special bar quality
mini-mill assets located in Pittsboro, Indiana. We agreed to pay $45 million for
the assets and announced plans to invest between $60 and $70 million of
additional capital to convert the Qualitech mini-mill to the production of
between 500,000 and 600,000 annual tons of merchant and reinforcing bar
products. We agreed to close the transaction within 25 days, subject to certain
conditions and approvals. In addition, we also announced our plans to complete
construction and start-up of this mini-mill within 12 months after the closing
of the transaction and to begin shipping our first products during the second
half of 2003. However, on August 2, 2002, Nucor Corporation filed suit against
Qualitech Steel SBQ LLC in Hendricks County, Indiana Superior Court, seeking to
enjoin Qualitech from selling its assets to us by reason of rights they allege
under a prior purchase agreement. On August 6, 2002, the court entered a
temporary restraining order prohibiting Qualitech from closing under our
purchase agreement pending a preliminary injunction hearing scheduled for August
19, 2002. On August 7, 2002, we intervened in this lawsuit to assert our rights
under our purchase agreement with Qualitech. On August 19, 2002, after the
conclusion of evidence at the preliminary injunction hearing, the Hendricks
County, Indiana Superior Court ruled that Nucor "has little, if any, chance of
prevailing at a trial based upon the evidence presented" and denied Nucor's
injunction request. On August 20, 2000, Nucor filed a notice of appeal with the
Indiana Court of Appeals. On September 6, 2002, we closed on and completed the
purchase.

     The continued pendency of this litigation, notwithstanding the completion
of our purchase, creates uncertainties with respect to our ability to maintain
our ownership of these assets or to implement our conversion and start-up plans
as previously announced. We may also be limited or delayed in achieving our
objectives based upon other unforeseen circumstances or events beyond our
control. We refer you to "Risk Factors -- We may be unable to maintain our
ownership of the Qualitech assets, or we may be delayed in the construction and
start-up of this mini-mill" for risks associated with this potential
acquisition.

                                  RISK FACTORS

     You should carefully consider the following risk factors and the other
information contained elsewhere or incorporated by reference in this prospectus
before making an investment decision.

RISKS RELATED TO OUR INDUSTRY

     IN RECENT YEARS, IMPORTS OF STEEL INTO THE UNITED STATES HAVE ADVERSELY
AFFECTED, AND MAY AGAIN ADVERSELY AFFECT, U.S. STEEL PRICES, WHICH WOULD IMPACT
OUR SALES, MARGINS AND PROFITABILITY

     Excessive imports of steel into the United States have in recent years, 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, but it has greatly increased as a result of an excess of
foreign steelmaking capacity and a weakening of certain foreign economies,
particularly in Eastern Europe, Asia and Latin America. The economic
difficulties in these countries have resulted in lower local demand for steel
products and have tended to encourage greater steel exports to the United States
at depressed prices.

     In addition, we believe the downward pressure on, and depressed levels of,
U.S. steel prices in 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. For
example, between 1998 and 2001, when imports of hot-rolled and cold-rolled
products increased dramatically, domestic steel producers, including us, were
adversely affected by unfairly priced or "dumped" imported steel. Even though
various protective actions taken by the U.S. government during 2001, including
the enactment of various steel import quotas and tariffs, have resulted in an
abatement of some steel imports during 2002, these protective measures are only
temporary, and, in fact, some have already been reversed or weakened by
exemptions. When these measures expire or if they are further relaxed, or if
increasingly higher U.S. steel prices enable foreign steelmakers to export their
steel products into the United States even with the presence of tariffs, the
resurgence of substantial imports of foreign steel could again create downward
pressure on U.S. steel prices.

     INTENSE COMPETITION AND EXCESS GLOBAL CAPACITY IN THE STEEL INDUSTRY MAY
CONTINUE TO EXERT DOWNWARD PRESSURE ON OUR PRICING

     We may not be able to compete effectively in the future as a result of
intense competition. Competition within the steel industry, both domestically
and worldwide, is intense and it is expected to remain so. We compete primarily
on the basis of (1) price, (2) quality and (3) the ability to meet our
customers' product needs and delivery schedules. Our primary competitors are
other mini-mills, which may have cost structures and management cultures more
similar to ours than integrated mills. We also compete with many integrated
producers of hot-rolled, cold-rolled and coated products, many of which are
larger and have substantially greater capital resources. The highly competitive
nature of the industry, in part, exerts downward pressure on prices for some of
our products. Further, over the past few years, approximately 30 domestic steel
producers have entered bankruptcy proceedings. In some cases, these previously
marginal producers have been able to emerge from bankruptcy reorganization with
lower and more competitive cost structures. In other cases, steelmaking assets
have been sold through bankruptcy proceedings to other steelmakers or to new
companies, at greatly depressed prices. The reemergence of these producers or
their successors may further increase the competitive environment in the steel
industry and contribute to price declines. In the case of certain product
applications, steel competes with other materials, including plastic, aluminum,
graphite composites, ceramics, glass, wood and concrete.

     In addition, global overcapacity in steel manufacturing and its negative
impact on U.S. steel pricing are likely to continue to persist and could have a
negative impact on our sales, margins and profitability. The U.S. steel industry
continues to be adversely impacted by excess global steel manufacturing
capacity. Over the last decade, the construction of new mini-mills, expansion
and improved production efficiencies of some integrated mills and substantial
expansion of foreign steel capacity have all led to the excess of manufacturing
                                        6


capacity. Increasingly, this overcapacity, combined with the high levels of
steel imports into the United States, has exerted downward pressure on domestic
steel prices, including the prices of our products, and has resulted in, at
times, a dramatic narrowing, or with many companies the elimination, of gross
margins.

     THE POSITIVE EFFECTS OF PRESIDENT BUSH'S MARCH 5, 2002 ORDER IN
CONTRIBUTING TO THE REDUCTION OF EXCESSIVE IMPORTS OF STEEL INTO THE UNITED
STATES HAVE BEEN AND MAY BE FURTHER LESSENED IF THERE ARE SUCCESSFUL APPEALS TO
THE WORLD TRADE ORGANIZATION BY THE EXPORTING COUNTRIES OR IF DOMESTIC OR
INTERNATIONAL POLITICAL PRESSURE CONTINUES TO RESULT IN A RELAXATION OF, OR
SUBSTANTIAL ADDITIONAL EXEMPTIONS FROM, THE TARIFFS CONTAINED IN THE ORDER

     If the amount, scope or duration of the Section 201 orders continue to be
eroded by exemptions or otherwise are lessened or adversely changed, it could
lead to a resurgence of flat-rolled steel imports, an increase of steel slab
imports and/or an increase in welded pipe and tube imports. Any of these results
would again put downward pressure on U.S. flat-rolled prices which would
negatively impact our sales, margins and profitability. On June 22, 2001, the
Bush Administration requested that the International Trade Commission, or ITC,
initiate an investigation under Section 201 of the Trade Act of 1974 to
determine whether steel is being imported into the United States in such
quantities as to be a substantial cause of serious injury to the U.S. steel
industry. In October 2001, the ITC found "serious injury" due to imports of
steel products, including the products we manufacture, and in December 2001, the
ITC recommended that the President impose tariffs of approximately 20%-40%, as
well as tariff quotas in connection with certain products such as steel slabs.
On March 5, 2002, President Bush, among other actions, imposed a three year
tariff of 30% for the first year, 24% for the second year and 18% for the third
year on imports of hot-rolled, cold-rolled and coated sheet, as well as on
imports of steel slabs in excess of a specified annual quota.

     Imports of flat-rolled steel have declined, in part, due to the imposition
of dumping duties that have been imposed on certain imports of foreign steel,
and, in part, due to the imposition of significant tariffs as a result of this
Section 201 action. These events have, in part, allowed us to begin restoring
prices on flat-rolled products. While the President's decision to implement a
Section 201 remedy is not appealable to U.S. courts, foreign governments may
appeal, and some have appealed, to the World Trade Organization, or WTO. The
European Union, Japan and other countries are currently prosecuting such
appeals. These dispute settlement proceedings at the WTO and further appeals to
the Appellate Body of the WTO generally take 15-24 months. Moreover, a number of
affected countries have imposed or threatened to impose various retaliatory
tariffs on U.S. steel or other products or have sought various product
exemptions from the imposition of the tariffs. As of the end of August 2002, the
U.S. government has granted more than 725 product exemptions pursuant to these
requests and more are likely to be requested and granted during 2003.
Accordingly, there is a risk that additional rulings adverse to the United
States or substantial additional political pressures could result in the
President changing the remedy, granting substantial further exemptions from the
remedy, or terminating the remedy entirely prior to the full three years,
although any such modification would apply only prospectively.

     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 AND THE INDUSTRIES WE SERVE

     The price of steel and steel products may fluctuate significantly due to
many factors beyond our control. This fluctuation directly affects the levels of
our production and our sales and earnings. The steel industry is highly
cyclical, sensitive to general economic conditions and dependent on the
condition of certain other industries. The demand for steel products is
generally affected by macroeconomic fluctuations in the United States and global
economies in which steel companies sell their products. For example, future
economic downturns, stagnant economies or currency fluctuations in the United
States or globally could decrease the demand for our products or increase the
amount of imports of steel into the United States either event of which would
decrease our sales, margins and profitability.

     In addition, a disruption or downturn in the automotive, oil and gas, gas
transmission, construction, commercial equipment, rail transportation,
appliance, agricultural and durable goods industries could negatively impact our
financial condition, production, sales, margins and earnings. We are also
particularly sensitive to trends and events, including strikes and labor unrest,
that may impact these industries. These industries are significant markets for
our products and are themselves highly cyclical.

RISKS RELATED TO OUR BUSINESS

     TECHNOLOGY, OPERATING AND START-UP RISKS ASSOCIATED WITH OUR IRON DYNAMICS
SCRAP SUBSTITUTE PROJECT MAY PREVENT US FROM REALIZING THE ANTICIPATED BENEFITS
FROM THIS PROJECT AND COULD RESULT IN A LOSS OF OUR INVESTMENT

     If we abandon our Iron Dynamics project, or if its process does not
succeed, we will not be able to realize the expected benefits of this project
and will suffer the loss of our entire investment. As of June 30, 2002, our
equity investment in the Iron Dynamics project was $158 million. Since 1997, our
wholly-owned subsidiary, Iron Dynamics, has tried to develop and commercialize a
pioneering process of producing a virgin form of iron that might serve as a
lower cost substitute for a portion of the metallic raw material mix that goes
into our electric arc furnaces to be melted into new steel. This scrap
substitute project is the first of its kind. It involves processes that are
based on various technical assumptions and new applications of technologies that
have yet to be commercially proven. Since our initial start-up in August 1999,
we have encountered a number of difficulties associated with major pieces of
equipment and with operating processes and systems. Throughout the latter part
of 1999 and 2000, our Iron Dynamics facility was shut down. During these shut
downs, we engaged in time consuming and expensive redesign, re-engineering,
reconstruction and retrofitting of major pieces of equipment, systems and
processes. As a result, the Iron Dynamics project has taken considerably longer
and has required us to expend considerably greater resources than originally
anticipated. While we made significant progress during these shut downs in
correcting various technical and other deficiencies, we have not yet been
successful in achieving the results necessary to bring production output up and
product costs down to the point of being commercially competitive. In February
2001, we re-started operations at our Iron Dynamics facility. However, in July
2001, we suspended these operations again, with no specific date set for
resumption of operations. This shut down was a result of:

     (1) higher than expected start-up and process refinement costs;

     (2) exceptionally high energy costs;

     (3) low production quantities achieved at the Iron Dynamics facility; and

     (4) historically low steel scrap pricing.

These factors made the cost of producing and using Iron Dynamics scrap
substitute at our flat-rolled mini-mill higher than our cost of purchasing and
using steel scrap. Furthermore, we believe that, even with additional
development and refinement to the equipment, technology systems and processes,
the Iron Dynamics facility may only be able to achieve monthly output levels
between 75%-85% of our original estimates, resulting in higher unit costs than
originally planned. We currently estimate that these additional developments and
refinements would, if implemented, cost approximately $15 million. However, we
are entitled to a $6 million refund from one of our equipment manufacturers in
connection with these improvements, which we would expect to apply toward this
cost. On July 10, 2002, we announced that we expect to begin experimental
production trials in the fourth quarter of 2002. If these trials prove
successful, we could begin commercial production in 2003. However, Iron Dynamics
may never become commercially operational.

     In addition, while we remain optimistic that the remaining start-up
difficulties with the equipment, technology, systems and processes can be
resolved, our Iron Dynamics facility may not be able to consistently operate or
be able to produce steel scrap substitute material in the quantities that will
enable it to be cost competitive. Moreover, in connection with any restart of
operations, our Iron Dynamics facility may experience additional shutdowns or
equipment failures and such shutdowns or failures may have a material adverse
impact on our liquidity cost structure and earnings.

     OUR SENIOR SECURED CREDIT AGREEMENT AND THE INDENTURE RELATING TO THE
9 1/2% SENIOR NOTES DUE 2009 CONTAIN RESTRICTIVE COVENANTS THAT MAY LIMIT OUR
FLEXIBILITY

     Restrictions and covenants in our existing debt agreements, as well as our
senior secured credit agreement and the indenture relating to the senior notes,
and any future financing agreements, may impair our ability to

                                        8


finance future operations or capital needs or to engage in other business
activities. Specifically, these agreements will restrict our ability to:

     - incur additional indebtedness;

     - pay dividends or make distributions with respect to our capital stock;

     - repurchase or redeem capital stock;

     - make investments;

     - create liens and enter into sale and leaseback transactions;

     - make capital expenditures;

     - enter into transactions with affiliates or related persons;

     - issue or sell stock of certain subsidiaries;

     - sell or transfer assets; and

     - participate in certain joint ventures, acquisitions or mergers.

     In addition, a breach of any of the restrictions in our debt agreements
could cause our indebtedness to become immediately due and payable and we may
not be able to obtain sufficient funds to make these accelerated payments. If
any debt is accelerated, our assets may also not be sufficient to repay in full
such indebtedness. The senior secured credit agreement also contains financial
covenants, such as a leverage ratio and an interest coverage ratio. A breach of
any of these covenants may also accelerate our debt.

     A SUBSTANTIAL PORTION OF OUR FLAT-ROLLED PRODUCTS ARE SOLD ON THE SPOT
MARKET, AND THEREFORE, OUR SALES, MARGINS AND EARNINGS ARE NEGATIVELY IMPACTED
BY DECREASES IN DOMESTIC FLAT-ROLLED STEEL PRICES

     Our sales, margins and earnings are negatively impacted by decreases in
domestic flat-rolled steel prices since a significant portion of our flat-rolled
products are sold on the spot market. As a result, we are vulnerable to
downturns in the domestic flat-rolled steel market. For the three year period
ended December 31, 2001, approximately 80% of our flat-roll products were sold
on the spot market under contracts with terms of twelve months or less.

     WEAKNESS IN THE AUTOMOTIVE INDUSTRY WOULD RESULT IN A SUBSTANTIAL REDUCTION
IN DEMAND FOR OUR PRODUCTS

     A prolonged weakness in the automotive industry would reduce the demand for
our products and decrease our sales. In addition, if automobile manufacturers
choose to incorporate more plastics, aluminum and other steel substitutes in
their automobiles, it could reduce demand for our products. Our sales and
earnings fluctuate due to the cyclical nature of the automotive industry. The
cyclical nature of the automotive industry is affected by such things as the
level of consumer spending, the strength or weakness of the U.S. dollar and the
impact of international trade and various factors, such as labor unrest and the
availability of raw materials, which affect the ability of the automotive
industry to actually build cars. While we do not presently sell a material
portion of our steel production directly to the automotive market, a substantial
portion of our sales to the intermediate steel processor and service center
market is resold to various companies in the automotive industry.

     WE MAY BE UNABLE TO PASS ON INCREASES IN THE COST OF SCRAP AND OTHER RAW
MATERIALS TO OUR CUSTOMERS WHICH WOULD REDUCE OUR EARNINGS

     If we are unable to pass on higher 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

                                        9


necessarily fluctuate in tandem with the price of steel. 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.

     WE HAVE PRIMARILY RELIED UPON ONE SUPPLIER TO MEET OUR STEEL SCRAP
REQUIREMENTS

     Since our inception, we have had an exclusive contract with OmniSource, one
of the largest scrap processors and brokers in the Midwest, to purchase steel
scrap. Our current agreement with OmniSource expires on December 31, 2004.
However, OmniSource may terminate the agreement at anytime on or after July 1,
2003. If the contract terminates for any reason, we would have to find another
supplier for steel scrap or develop our own scrap purchasing capability. We may
be unable to secure substitute arrangements for steel scrap on the same or
better terms as those in our contract with OmniSource. In addition, if our
contract is adversely changed for any reason, we may experience an increase in
our cost of goods sold.

     For 2001 and the six months ended June 30, 2002, we purchased 1.5 million
tons and 910,000 tons of steel scrap and scrap substitutes from OmniSource,
respectively, which represent approximately 87% and 83% of our total scrap tons
purchased during those periods.

     THERE MAY BE POTENTIAL CONFLICTS OF INTEREST WITH REGARD TO OUR
RELATIONSHIP WITH OMNISOURCE

     With respect to any dispute between us and OmniSource involving our
existing contract, including its remaining term, any future contract, or in
connection with the terms of any commercial transaction, OmniSource may be
viewed as having a conflict of interest between what it perceives as being best
for itself as a seller of scrap and what is best for us as a buyer of scrap. We
may not be able to resolve potential conflicts and if we do resolve them, we may
receive a less favorable resolution since we are dealing with OmniSource rather
than an unaffiliated person. The chairman of the board and chief executive
officer of OmniSource is also a member of our board of directors and is a
substantial stockholder of Steel Dynamics. This person has obligations to us as
well as to OmniSource and may have conflicts of interest with respect to matters
potentially or actually involving or affecting us and OmniSource. OmniSource
also supplies scrap to many other customers, including other steel mills.

     WE RELY UPON A SMALL NUMBER OF MAJOR CUSTOMERS FOR A SUBSTANTIAL PERCENTAGE
OF OUR SALES

     A loss of any large customer or group of customers could materially reduce
our sales and earnings. We have substantial business relationships with a few
large customers. In 2001 and for the six months ended June 30, 2002, our Butler
mini-mill's top ten customers accounted for approximately 48% and 54% of our
total net sales, respectively. During those periods, our largest customer,
Heidtman, accounted for approximately 18% and 16% of our total net sales. We
expect to continue to depend upon a small number of customers for a significant
percentage of our total net sales, and cannot assure you that any of them will
continue to purchase steel from us.

     THERE MAY BE POTENTIAL CONFLICTS OF INTEREST WITH REGARD TO OUR
RELATIONSHIP WITH HEIDTMAN STEEL PRODUCTS, INC.

     If a dispute arises between us and Heidtman, we may be viewed as having a
conflict of interest. What is best for Heidtman as a buyer and what is best for
us as a product seller may be at odds. We may be unable to resolve potential
conflicts. If we do resolve them, we may receive a less favorable resolution
since we are dealing with Heidtman rather than an unaffiliated person. Heidtman
is an affiliate of one of our large stockholders and its president and chief
executive officer serves as one of our directors. This person has obligations to
us as well as to Heidtman and may have conflicts of interest with respect to
matters potentially or actually involving or affecting us and Heidtman.

     START-UP AND OPERATING RISKS ASSOCIATED WITH THE CONSTRUCTION OF OUR
COLUMBIA CITY STRUCTURAL STEEL AND RAIL MINI-MILL COULD RESULT IN MATERIALLY
GREATER OPERATING COSTS THAN THOSE WE HAVE ANTICIPATED

     Start-up and operating risks associated with the construction of our
Columbia City mini-mill may result in materially greater operating costs than we
initially expected. At our Columbia City mini-mill, we are subject to all of the
general risks associated with the construction and start-up of a new mini-mill.
These risks

                                        10


involve construction delays, cost overruns and start-up difficulties. We could
also experience operational difficulties after start-up that could result in our
inability to operate our Columbia City mini-mill at full or near full capacity
or at all.

     UNEXPECTED EQUIPMENT FAILURES MAY LEAD TO PRODUCTION CURTAILMENTS OR
SHUTDOWNS

     Interruptions in our production capabilities will inevitably increase our
production costs, and reduce our sales and earnings for the affected period. In
addition to equipment failures, our facilities are also subject to the risk of
catastrophic loss due to unanticipated events such as fires, explosions or
violent weather conditions. Our manufacturing processes are dependent upon
critical pieces of steelmaking equipment, such as our furnaces, continuous
casters and rolling equipment, as well as electrical equipment, such as
transformers, and this equipment may, on occasion, be out of service as a result
of unanticipated failures. We have experienced and may in the future experience
material plant shutdowns or periods of reduced production as a result of such
equipment failures.

     WE DEPEND HEAVILY ON OUR SENIOR MANAGEMENT AND WE MAY BE UNABLE TO REPLACE
KEY EXECUTIVES IF THEY LEAVE

     The loss of the services of one or more members of our senior management
team or our inability to attract, retain and maintain additional senior
management personnel could harm our business, financial condition, results of
operations and future prospects. Our senior management founded our company,
pioneered the development of thin-slab, flat-rolled technology and directed the
construction of our Butler mini-mill and Columbia City structural mini-mill. Our
operations and prospects depend in large part on the performance of our senior
management team, including Keith E. Busse, president and chief executive
officer, Mark D. Millett, vice president and general manager of our flat-roll
division, Richard P. Teets, Jr., vice president and general manager of our
structural division, Tracy L. Shellabarger, vice president and chief financial
officer and John W. Nolan, vice president, sales and marketing. Although these
senior managers have each been employees and stockholders of Steel Dynamics for
more than seven years, these individuals may not remain with us as employees. In
addition, we may not be able to find qualified replacements for any of these
individuals if their services are no longer available. We do not have key man
insurance on any of these individuals.

     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 our 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 ours;

     - the difficulty of integrating the acquired operations and personnel into
       our existing business;

     - the potential disruption of our ongoing business;

     - the diversion of resources;

     - the inability of management to maintain uniform standards, controls,
       procedures and polices;

     - 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 contractual or operational liability to our 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

                                        11


     - 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.

     WE MAY BE UNABLE TO MAINTAIN OUR OWNERSHIP OF THE QUALITECH ASSETS, OR WE
MAY BE DELAYED IN THE CONSTRUCTION AND START-UP OF THIS MINI-MILL

     We may not be able to maintain our ownership of the assets of Qualitech
Steel SBQ LLC, which we purchased on September 6, 2002, as a result of
litigation initiated on August 2, 2002 by Nucor Corporation in Hendricks County,
Indiana Superior Court, challenging Qualitech's right to sell the assets to us,
or we may be delayed in the construction and start-up of this mini-mill as a
result of the litigation or other events outside our control. Nucor originally
sought to preliminarily and permanently enjoin Qualitech from selling its assets
to us pursuant to a July 26, 2002 asset purchase agreement, claiming a right to
those assets by reason of a prior purchase agreement. On August 6, 2002, the
court entered a temporary restraining order prohibiting Qualitech from closing
under our purchase agreement and scheduled a preliminary injunction hearing on
August 19, 2002. On August 7, 2002, we intervened as a party in that litigation
to assert our rights under the Qualitech Agreement. At the conclusion of the
evidence on August 19, 2002, the Hendricks County Superior Court denied Nucor's
motion for an injunction, but on August 20, 2002, Nucor appealed that decision
to the Indiana Court of Appeals. Notwithstanding the continued pendency of this
litigation, we closed on and consummated the purchase of the Qualitech assets on
September 6, 2002. If Nucor prevails in its claim of priority purchase rights to
the Qualitech assets, we could be precluded from maintaining ownership of those
assets, might be required to convey the Qualitech assets back to Qualitech or to
Nucor, and might be liable to Nucor for damages. On the other hand, having now
purchased the Qualitech assets, even if Qualitech's right to sell us the
Qualitech assets is upheld on appeal, we may exceed our current estimates of
investing between $60 and $70 million of additional capital to convert the
Qualitech mini-mill into a mini-mill for the production of merchant and
reinforcing bar. We are also subject to regulatory approval and to construction
and start-up delays and operational risks associated with the conversion of the
Qualitech mini-mill. We may also be delayed either as a result of the litigation
or as a result of other unforeseen circumstances or events beyond our control.

     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 environmental
laws and 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 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 such laws and regulations are an inherent part of our business.
Although we are not currently involved in any compliance or remediation
activities, it is possible that future conditions may develop, arise or be
discovered that create substantial environmental compliance or remediation
liabilities and costs. For example, our steelmaking operations produce certain
waste products, such as electric arc furnace dust, which are classified as
hazardous waste and must be properly disposed of under applicable environmental
laws. 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 was caused in whole or in part by third parties. While we
believe that we can comply with environmental legislation and regulatory
requirements and that the costs of doing so have been included within our
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 we may become, subject to substantial monetary fines and penalties
for violation of applicable laws, regulations or administra-

                                        12


tive conditions. 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 or
personal injury.

RISKS RELATED TO THE NOTES

     WE HAVE SUBSTANTIAL INDEBTEDNESS AND DEBT SERVICE REQUIREMENTS WHICH LIMITS
OUR FINANCIAL AND OPERATING FLEXIBILITY

     Our substantial indebtedness limits our financial and operating
flexibility. For example, it could:

     - 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 obtain additional financing for working capital,
       capital expenditures, acquisitions or general corporate 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.

     Our ability to satisfy our debt obligations will depend upon our future
operating performance, which in turn will depend upon the successful
implementation of our strategy and upon financial, competitive, regulatory,
technical and other factors, many of which are beyond our control. If we are not
able to generate sufficient cash from operations to make payments under our
credit agreements or to meet our other debt service obligations, we will need to
refinance our indebtedness. Our ability to obtain such financing will depend
upon our financial condition at the time, the restrictions in the agreements
governing our indebtedness and other factors, including general market and
economic conditions. If such refinancing were not possible, we could be forced
to dispose of assets at unfavorable prices. Even if we could obtain such
financing, we cannot be sure that it would be on terms that are favorable to us.
In addition, we could default on our debt obligations.

     As of June 30, 2002, we had $552 million of indebtedness. This indebtedness
represented approximately 53% of our total consolidated capitalization,
including current maturities of long-term debt.

     DESPITE OUR SUBSTANTIAL INDEBTEDNESS, WE MAY STILL INCUR SIGNIFICANTLY MORE
DEBT, WHICH COULD FURTHER INCREASE THE RISK DESCRIBED ABOVE

     Any additional debt could be more senior to the notes and could increase
the risk described above. The terms of the new senior secured credit agreement
and the indenture related to the notes do not prohibit us from incurring
significant additional indebtedness in the future.

     WE MAY NOT HAVE SUFFICIENT CASH FLOW TO MAKE PAYMENTS ON YOUR NOTES AND OUR
OTHER DEBT

     If our cash flow and capital resources are insufficient to allow us to make
scheduled payments on your 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 new 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.

     Our ability to pay principal and interest on your 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

                                        13


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.

     BECAUSE THE NOTES ARE EFFECTIVELY SUBORDINATED TO OUR SECURED DEBT, IF WE
ARE IN DEFAULT ON OUR SECURED DEBT YOU MAY NOT RECEIVE FULL PAYMENT ON YOUR
NOTES

     If we are in default on our secured obligations, you may not receive
principal and interest payment on your notes. Our obligations under the new
senior secured credit agreement will be secured by a significant portion of our
assets. In contrast, our obligations under the notes are unsecured. As a result,
the notes are subordinated to our obligations under the new senior secured
credit agreement as well as any other secured debt. As of December 31, 2001,
after giving effect to the Iron Dynamics credit agreement settlement transaction
and the refinancing, including this offering, we would have had $275.0 million
of secured indebtedness outstanding (excluding indebtedness of our
subsidiaries), and the ability to borrow $75.0 million more under our credit
facility.

     THE NOTES ARE EFFECTIVELY SUBORDINATED TO ALL OF THE LIABILITIES OF OUR
NON-GUARANTOR SUBSIDIARIES

     Upon consummation of this offering, SDI Investment Company was the only
subsidiary that guaranteed the notes. Thus far during 2002, Ferrous Resources,
LLC, STLD Holdings, Inc. and Dynamic Bar Products, LLC also became guarantors.
All of our other subsidiaries, including Iron Dynamics and New Millennium, are
not guarantors of the notes. As a result, the notes are effectively subordinated
to all of the liabilities of our subsidiaries that are not guarantors. As of
June 30, 2002, the non-guarantor subsidiaries had $28.1 million of liabilities
outstanding, including $23.3 million of indebtedness, but excluding intercompany
liabilities and guarantees of our new senior secured credit agreement.

     OUR SENIOR SECURED CREDIT AGREEMENT AND THE INDENTURE RELATING TO THE NOTES
CONTAIN RESTRICTIVE COVENANTS THAT MAY LIMIT OUR FLEXIBILITY

     Restrictions and covenants in our senior secured credit agreement and the
indenture relating to the notes, and any future financing agreements, may
substantially limit 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 investments;

     - create liens and enter into sale and leaseback transactions;

     - make capital expenditures;

     - enter into transactions with affiliates or related persons;

     - issue or sell stock of certain subsidiaries;

     - sell or transfer assets; and

     - participate in certain joint ventures, acquisitions or mergers.

     A breach of any of the restrictions or covenants in our debt agreements
could cause a default under our new senior secured credit agreement, other debt
or the notes. A significant portion of our indebtedness then may become
immediately due and payable. We are not certain whether we would have, or be
able to obtain, sufficient funds to make these accelerated payments, including
payments on the notes. If any senior debt is accelerated, our assets may not be
sufficient to repay in full such indebtedness and our other indebtedness,
including the notes, in which event the interests of the senior debt lenders may
conflict with the interests of the holders of the notes.

                                        14


     All of our subsidiaries, other than SDI Investment Company, Ferrous
Resources, LLC and STLD Holdings, Inc., are unrestricted subsidiaries. The
unrestricted subsidiaries accounted for 14.7% of total assets as of June 30,
2002 and for 11.4% of total net sales for the six months ended June 30, 2002 and
had a net loss of $3.1 million for the six months ended June 30, 2002.

     FEDERAL AND STATE LAWS PERMIT A COURT TO VOID THE SUBSIDIARY GUARANTEES
UNDER CERTAIN CIRCUMSTANCES

     We cannot be sure as to whether a court would determine that immediately
after the issuance of the notes and the subsidiary guarantees, each of the
subsidiary guarantors would be solvent, would have sufficient capital to carry
on its business and would be able to pay its debts as they mature or what
standard a court would apply in making these determinations.

     The guarantee of the notes by SDI Investment may be subject to review under
federal or state fraudulent transfer laws. As of June 30, 2002, SDI Investment
had total assets of $29.9 million. While the relevant laws may vary from state
to state, under such laws, a subsidiary guarantee will be a fraudulent
conveyance if (1) any of our subsidiaries made guarantees with the intent of
hindering, delaying or defrauding creditors, or (2) any of the subsidiary
guarantors received less than reasonably equivalent value or fair consideration
in return for its guarantee, and in the case of (2) only, one of the following
is also true:

     - any of the subsidiary guarantors was insolvent, or became insolvent, at
       the time of the guarantee;

     - the guarantee left the applicable subsidiary guarantor with an
       unreasonably small amount of capital; or

     - the applicable subsidiary guarantor intended to, or believed that it
       would, be unable to pay its debts as they matured.

     If any guarantee were to be deemed a fraudulent conveyance, a court could,
among other things, void any of the subsidiary guarantors' obligations under its
guarantee and require the repayment of any amounts paid thereunder. Generally,
an entity will be considered insolvent if:

     - the sum of its debts is greater than the value of its property;

     - the present fair value of its assets is less than the amount that it will
       be required to pay on its existing debts as they become due; or

     - it cannot pay its debts as they become due.

     WE ARE PROHIBITED FROM, AND MAY BE UNABLE TO, REPURCHASE THE NOTES UPON A
CHANGE OF CONTROL, WHICH WOULD CAUSE DEFAULTS UNDER THE INDENTURE FOR THE NOTES
AND OUR NEW SENIOR SECURED CREDIT AGREEMENT AND POSSIBLY OTHER INDEBTEDNESS WE
MAY INCUR IN THE FUTURE

     Upon the occurrence of a change of control as defined in the indenture for
the notes, we will be required to offer to purchase the notes at 101% of the
principal amount of the notes, together with accrued and unpaid interest, if
any, to the date of purchase. We are prohibited under the new senior secured
credit facility, and may be prohibited under indebtedness we may incur in the
future, from purchasing any notes prior to their stated maturity. In such
circumstances, we will be required to repay all or a portion of the outstanding
principal of, and pay any accrued and unpaid interest on, indebtedness under the
new senior secured credit agreement and any such other future indebtedness or
obtain the requisite consent from the lenders under the new senior secured
credit agreement and the holders of any such other future indebtedness to permit
the repurchase of the notes. If we are unable to repay all of such indebtedness
or are unable to obtain the necessary consents, we will be unable to offer to
repurchase the notes, which would constitute an event of default under the
indenture for the notes, which itself would also constitute a default under our
new senior secured credit agreement and could constitute a default under the
terms of any future indebtedness we may incur.

     In addition, the events that constitute a change of control under the
indenture for the notes may also be events of default under the new senior
secured credit agreement or other indebtedness we may incur in the future.

     IF YOU FAIL TO EXCHANGE YOUR OLD NOTES, YOU MAY BE UNABLE TO SELL THEM

                                        15


     If you are a holder of old notes after the exchange offer, you may be
unable to sell your old notes. Because we did not register the old notes under
the Securities Act or any state securities laws and we do not intend to do so
after the exchange offer, the old notes may only be transferred in limited
circumstances under applicable securities laws. If you do not exchange your old
notes in the exchange offer, you will lose your right to have your old notes
registered under the Securities Act.

     AN ACTIVE TRADING MARKET MAY NOT DEVELOP FOR THE EXCHANGE NOTES

     An active trading market may not develop for your notes, you may not be
able to sell your Exchange Notes, or, even if you can sell your Exchange Notes,
you may not be able to sell them at a price equal to or above the price you
paid. 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 Nasdaq. The liquidity of the trading market in the Exchange Notes,
and the market prices quoted for the Exchange Notes, may be adversely affected
by changes in the overall market for these types of securities and by changes in
our financial performance or prospects or in the prospects for companies in our
industry generally.

                   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......................   Up to $200 million aggregate principal amount
                                 of our 9 1/2% senior notes due March 15, 2009
                                 that have been registered under the Securities
                                 Act of 1933, as amended, in exchange for an
                                 equal face amount of our outstanding
                                 unregistered 9 1/2% senior notes due March 15,
                                 2009.

                                 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 October [--], 2002,
                                 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.

Resales of the Exchange
Notes.........................   We believe that Exchange Notes to be issued 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 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.

                                 Our belief is based on interpretations by the
                                 staff of the Commission, as set forth in
                                 no-action letters issued to third parties
                                 unrelated to us.

                                        17


                                 Each 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 and you are an
                                 affiliate of Steel Dynamics, did not acquire
                                 the Exchange Notes in the ordinary course of
                                 your business, or you wish to tender your old

                                 of participating, or for the purpose of

                                 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

Change of Control.............   Upon 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 interest. 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 existing and future senior unsecured
                                 indebtedness of our company and will rank
                                 senior to any subordinated indebtedness created
                                 in the future. The notes will be effectively
                                 subordinated to our secured indebtedness, to
                                 the extent of the assets securing that
                                 indebtedness, including indebtedness under our
                                 new senior secured credit agreement.

                                 As of June 30, 2002, we had $573.7 million of
                                 indebtedness and long-term contingent
                                 obligations outstanding, $275 million of which
                                 was secured indebtedness under our new senior
                                 secured credit agreement. The notes will also
                                 be effectively subordinated to all of the
                                 liabilities of our subsidiaries. As of June 30,
                                 2002, our subsidiaries had approximately $28.1
                                 million of liabilities outstanding, including
                                 $23.3 million of indebtedness, but excluding
                                 intercompany liabilities.

                                 All of our subsidiaries, other than SDI
                                 Investment Company, Ferrous Resources, LLC,
                                 STLD Holdings, Inc. and Dynamic Bar Products,
                                 LLC, will be unrestricted subsidiaries. The
                                 unrestricted subsidiaries accounted for 15% of
                                 total assets as of June 30, 2002 and for 11% of
                                 total net sales for the six months ended June
                                 30, 2002 and had a net loss of $3.1 million for
                                 the six months ended June 30, 2002.

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.

                                        22


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 terms of which are identical in all material respects to the Exchange
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 $195 million after deduction of the expenses related to the
offerings.

                       RATIO OF EARNINGS TO FIXED CHARGES

                     SELECTED FINANCIAL AND OPERATING DATA

     The following table sets forth selected consolidated financial and
operating data of Steel Dynamics. The selected consolidated financial and
operating data as of and for each of the years in the five-year period ended
December 31, 2001 were derived from our audited consolidated financial
statements. The selected consolidated financial and operating data as of and for
the six months ended June 30, 2001 and 2002 were derived from our unaudited
consolidated financial statements. These unaudited consolidated financial
statements include, in our opinion, all adjustments, consisting of normal
recurring adjustments, necessary to present fairly the data for such periods.
Operating results for interim periods are not necessarily indicative of a full
year's operations. You should read the following data in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and our consolidated financial statements and notes incorporated by
reference in this prospectus.

     You should also read the following information in conjunction with the data
in the table on the following page:

     - Commercial grade production began January 2, 1996.

     - Our 1997 extraordinary loss of $7.6 million (net of tax benefit of $5.1
       million) consisted of prepayment penalties and the write-off of
       capitalized financing costs associated with the amendment of our credit
       facility, effective June 30, 1997.

     - Our first quarter 2002 extraordinary loss of $2.0 million (net of tax
       benefit of $1.2 million) consisted of prepayment penalties and the
       write-off of capitalized financing costs associated with the refinancing
       of our credit facilities, effective March 26, 2002.

     - "Operating profit per net ton shipped" represents operating income before
       start-up costs divided by net ton shipments. Beginning July 1, 2000, net
       shipments included shipments from our steel fabrication subsidiary, New
       Millennium. Beginning March 1, 2001, net shipments also included
       shipments from our secondary-steel brokering subsidiary, Paragon Steel.

     - "Hot band production" refers to our flat-roll mini-mill's total
       production of finished coiled product. "Prime tons" refer to hot bands
       produced, which meet or exceed quality standards for surface, shape and
       metallurgical properties.

     - "Yield percentage" refers to our flat-roll mini-mill's tons of finished
       product divided by tons of raw materials.

     - "Effective capacity utilization" is the flat-roll mini-mill's ratio of
       tons produced for the operational month to the operational month's
       capacity. For the data disclosed in the periods ended December 31, 1996
       and 1997, we used an annual capacity of 1.4 million tons for this
       calculation. For the data disclosed in the periods ended December 31,
       1999 and 2000, and September 30, 2000 and 2001, we used an annual
       capacity of 2.2 million tons. For the data disclosed in the period ended
       December 31, 1998, we used an annual capacity of 1.8 million tons.

(1) EBITDA represents income before extraordinary items, income taxes, interest
    expense (net of interest income), depreciation and amortization. EBITDA is
    not a measure of operating income, operating performance or liquidity under
    generally accepted accounting principles, or GAAP. We have presented EBITDA
    because certain investors may find it to be a useful tool for analyzing and
    comparing operating performance and for determining a company's ability to
    service and/or incur debt. We believe that EBITDA,
                                        26


    as presented, represents a useful measure of assessing the performance of
    our ongoing operating activities, as it reflects our earnings trends without
    the impact of a number of non-cash charges. We use targets and positive
    trends in EBITDA to measure performance, and some of our creditors use
    EBITDA to assess our debt covenant compliance. Nevertheless, EBITDA should
    not be considered in isolation or as a substitute for operating income (as
    determined in accordance with GAAP) as an indicator of our operating
    performance, or cash flow from operating activities (as determined in
    accordance with GAAP) as a measure of our liquidity. In addition, companies
    calculate EBITDA differently and therefore, EBITDA, as presented for us may
    not be comparable to EBITDA reported by other companies.

(2) Interest includes capitalized interest.

(3) For purposes of calculating our ratio of earnings to fixed charges, earnings
    consist of earnings from continuing operations before income taxes, adjusted
    for the portion of fixed charges deducted from these earnings, plus
    amortization of capitalized interest. Fixed charges consist of interest on
    all indebtedness, including capitalized interest, and amortization of debt
    issuance costs. In 2001, our earnings were insufficient to cover our fixed
    charges by $7.3 million.

                          TERMS OF THE EXCHANGE OFFER

     We are offering to exchange our 9 1/2% Senior Notes Due March 15, 2009 that
have been registered under the Securities Act of 1933, as amended, in exchange
for an equal face amount of our outstanding unregistered 9 1/2% Senior Notes Due
March 15, 2008 that were issued on March 26, 2002.

     We will accept up to a maximum face amount of $200 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 March 26, 2002 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. In connection with this issuance, we also entered into the
indenture and the registration rights agreement. These agreements require 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 indenture relating to the notes and the registration
rights agreement have been filed 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

                                        29


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 six 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. 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, $200.0 million in aggregate principal
amount of 9 1/2% notes due 2009 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.

                                        30


EXPIRATION DATE; AMENDMENTS

     The exchange offer will expire at 5:00 p.m., New York City time, on October
[--], 2002, 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

                                        31


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

                                        32


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

                                        33


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

                                        34


     - 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 or a telex or telegram 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

                                        35


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.

                       DESCRIPTION OF THE EXCHANGE NOTES

     We will issue the Exchange Notes (which, together with the old notes not
exchanged, are referred to as the Notes) under an Indenture, to be dated as of
the Closing Date, among Steel Dynamics, as issuer, SDI Investment Company, as
guarantor, and Fifth Third Bank, Indiana, as trustee. The terms of the notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939. Any old notes that remain
outstanding after the consummation of the exchange offer and 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 under the subheading
"-- Certain Definitions." For purposes of this "Description of the Notes," term
"Steel Dynamics" refers only to Steel Dynamics, Inc., and not to any of its
subsidiaries.

     The following description is only a summary of the material provisions of
the Indenture. We urge you to read the Indenture because it, not this
description, define your rights as holders of the notes. You may request copies
of these agreements at our address set forth under the heading "Where You Can
Find More Information."

     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." 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 proposed
form of Indenture is available upon request from Steel Dynamics. 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 $200 million aggregate principal amount, and will mature on
March 15, 2009. Subject to the covenants described below under "Covenants" and
applicable law, Steel Dynamics may issue additional Notes ("Additional Notes")
under the Indenture. The old Notes, and any Exchange Notes issued as described
in this prospectus, and any Additional Notes subsequently issued would be
treated as a single class for all purposes under the Indenture.

     Each Note will initially bear interest at the rate per annum shown on the
cover page of this prospectus from the Closing Date or from the most recent
interest payment date to which interest has been paid. Interest on the Notes
will be payable semiannually on March 15 and September 15 of each year,
commencing September 15, 2002. Interest will be paid to Holders of record at the
close of business on the March 1 or September 1 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 six months after the Closing Date, 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."

     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. If you give Steel Dynamics wire transfer instructions, Steel Dynamics
will pay all principal, premium and interest on your Notes in accordance with
your instructions. If you do not give Steel Dynamics wire transfer instructions,
payments of principal, premium and interest will be made at the office or agency
of the paying agent which will initially be the Trustee, unless Steel Dynamics
elects to make interest payments by check mailed to the Holders.

                                        37


     The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount and multiples of $1,000. See
"-- Book-Entry; Delivery and Form." No service charge will be made for any
registration of transfer or exchange of 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.

OPTIONAL REDEMPTION

     Steel Dynamics may redeem the Notes at any time on or after March 15, 2006.
The redemption price for the 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 March 15 of the
years indicated below:



YEAR                                                          REDEMPTION PRICE
----                                                          ----------------
                                                           
2006........................................................      104.750%
2007........................................................      102.375
2008 and thereafter.........................................      100.000


     In addition, at any time prior to March 15, 2005, Steel Dynamics may redeem
up to 35% of the principal amount of the Notes with the Net Cash Proceeds of one
or more sales of its Capital Stock (other than Disqualified Stock) at a
redemption price (expressed as a percentage of principal amount) of 109.500%,
plus accrued interest to the redemption date; provided that at least 65% of the
aggregate principal amount of 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 Capital 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 Notes are to be redeemed,
selection of the Notes for redemption will be made by the Trustee:

     - in compliance with the requirements of the principal national securities
       exchange, if any, on which the Notes are listed, or,

     - if the Notes are not 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 Note of $1,000 in principal amount or less shall be redeemed in
part. If any Note is to be redeemed in part only, the notice of redemption
relating to such Note will state the portion of the principal amount to be
redeemed. A new Note in principal amount equal to the unredeemed portion will be
issued upon cancellation of the original Note.

GUARANTEES

     Payment of the principal of, premium, if any, and interest on the Notes
will be Guaranteed, jointly and severally, on an unsecured unsubordinated basis
by SDI Investment Company, Ferrous Resources, LLC, STLD Holdings, Inc. and
Dynamic Bar Products, LLC. In addition, each future Restricted Subsidiary, other
than a Foreign Subsidiary, will Guarantee the payment of the principal of
premium if any and interest on the Notes. Only SDI Investment Company was a
Restricted Subsidiary on the Closing Date. All of Steel Dynamics' other
Subsidiaries existing on the Closing Date were not Restricted Subsidiaries nor
guarantors of the Notes.

     The obligations of a Subsidiary Guarantor under its 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 Note Guarantee will be entitled to
contribution from any other Subsidiary Guarantor.

     The 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 or (2) the designation of such
Subsidiary Guarantor as an Unrestricted Subsidiary, in each case in compliance
with the terms of the Indenture.

                                        38


RANKING

     The 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. The 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.

     As of June 30, 2002, Steel Dynamics and the Initial Subsidiary Guarantor
had $528.4 million of consolidated indebtedness outstanding, $275.0 million of
which was secured indebtedness under the Credit Agreement. The Credit Agreement
is secured by substantially all of the assets of Steel Dynamics and its wholly
owned subsidiaries, other than Iron Dynamics until such time as the IDI Credit
Agreement is terminated in accordance with the Settlement Agreement. The Credit
Agreement is secured by the capital stock and other equity interests of Steel
Dynamics in its subsidiaries. The Notes are effectively subordinated to such
indebtedness to the extent of such security interests.

     The Notes and the Note Guarantees are effectively subordinated to all of
the liabilities of the subsidiaries of Steel Dynamics that do not Guarantee the
Notes. As of June 30, 2002, these subsidiaries had $28.1 million of liabilities
outstanding, including $23.3 million of indebtedness, excluding their guarantee
of Steel Dynamics' obligations under the Credit Agreement.

SINKING FUND

     There will be no sinking fund payments for the 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 proposed form of Registration Rights Agreement is
available from Steel Dynamics upon request.

     Steel Dynamics and the Initial Subsidiary Guarantor have agreed with the
Placement Agents, for the benefit of the Holders, that they will use their 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 Notes for an issue of unsubordinated notes of Steel Dynamics (the "Exchange
Notes"), guaranteed by the Subsidiary Guarantors, with terms identical to the
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. For
each 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 Notes so surrendered or, if no interest has been paid on such
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 Notes validly surrendered in accordance with the terms
of the Exchange Offer. Notes not tendered in the Exchange Offer will bear
interest at the rate set forth on the cover page of this memorandum 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 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 Notes covered by a Shelf Registration

                                        39


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 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 six 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 memorandum. 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
memorandum.

CERTAIN COVENANTS

     OVERVIEW

     In the Indenture, Steel Dynamics will agree to covenants that limit its and
its Restricted Subsidiaries' ability, among other things, to:

     - incur additional debt;

     - pay dividends, acquire shares of capital stock, make payments on
       subordinated debt or make investments;

     - place limitations on distributions from Restricted Subsidiaries;

     - issue or sell capital stock of Restricted Subsidiaries;

     - issue guarantees;

     - sell or exchange assets;

     - enter into transactions with shareholders and affiliates;

     - create liens; and

     - effect mergers.

     In addition, if a Change of Control occurs, each Holder of Notes will have
the right to require Steel Dynamics to repurchase all or a part of the Holder's
Notes at a price equal to 101% of their principal amount, plus any accrued
interest to the date of repurchase. Only SDI Investment Company was a Restricted
Subsidiary on the Closing Date.

     LIMITATION ON INDEBTEDNESS

     (a) Steel Dynamics will not, and will not permit any of its Restricted
Subsidiaries to, Incur any Indebtedness (other than the Notes, the Note
Guarantees and other Indebtedness existing on the Closing Date); provided that
Steel Dynamics or any Subsidiary Guarantor may Incur Indebtedness, and any
Restricted Subsidiary may Incur Acquired Indebtedness, if, after giving effect
to the Incurrence of such Indebtedness and the receipt and application of the
proceeds therefrom, the Interest Coverage Ratio would be greater than 2.25:1.

     Notwithstanding the foregoing, Steel Dynamics and any Restricted Subsidiary
(except as specified below) may Incur each and all of the following:

          (1) Indebtedness of Steel Dynamics or any Subsidiary Guarantor
     outstanding at any time under the Credit Agreement in an aggregate
     principal amount (together with refinancings thereof) not to exceed

     permanently repaid as provided under the "Limitation on Asset Sales"
     covenant or (b) the sum of the amounts equal to (x) 60% of the consolidated
     book value of the inventory of Steel Dynamics and the Subsidiary Guarantors
     and (y) 85% of the consolidated book value of the accounts receivable of
     Steel Dynamics and the Subsidiary Guarantors, in each case as of the most
     recently ended fiscal quarter of Steel Dynamics for which reports have been
     filed with the SEC or provided to the Trustee;

          (2) Indebtedness owed (A) to Steel Dynamics or any Subsidiary
     Guarantor evidenced by an unsubordinated promissory note or (B) to any
     other Restricted Subsidiary; provided that (x) any event which results in
     any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
     subsequent transfer of such Indebtedness (other than to Steel Dynamics or
     another Restricted Subsidiary) shall be deemed, in each case, to constitute
     an Incurrence of such Indebtedness not permitted by this clause (2) and (y)
     if Steel Dynamics or any Subsidiary Guarantor is the obligor on such
     Indebtedness, such Indebtedness must be expressly subordinated in right of
     payment to the Notes, in the case of Steel Dynamics or the Note Guarantee,
     in the case of a Subsidiary Guarantor;

          (3) Indebtedness issued in exchange for, or the net proceeds of which
     are used to refinance or refund, then outstanding Indebtedness (other than
     Indebtedness outstanding under clause (2) or (5)) and any refinancings
     thereof in an amount not to exceed the amount so refinanced or refunded
     (plus premiums, accrued interest, fees and expenses); provided that (a)
     Indebtedness the proceeds of which are used to refinance or refund the
     Notes or Indebtedness that is pari passu with, or subordinated in right of
     payment to, the Notes or a Note Guarantee shall only be permitted under
     this clause (3) if (x) in case the Notes are refinanced in part or the
     Indebtedness to be refinanced is pari passu with the Notes or a Note
     Guarantee, such new Indebtedness, by its terms or by the terms of any
     agreement or instrument pursuant to which such new Indebtedness is
     outstanding, is expressly made pari passu with, or subordinate in right of
     payment to, the remaining Notes or the Note Guarantee, or (y) in case the
     Indebtedness to be refinanced is subordinated in right of payment to the
     Notes or a Note Guarantee, such new Indebtedness, by its terms or by the
     terms of any agreement or instrument pursuant to which such new
     Indebtedness is issued or remains outstanding, is expressly made
     subordinate in right of payment to the Notes or the Note Guarantee at least
     to the extent that the Indebtedness to be refinanced is subordinated to the
     Notes or the Note Guarantee, (b) such new Indebtedness, determined as of
     the date of Incurrence of such new Indebtedness, does not mature prior to
     the Stated Maturity of the Indebtedness to be refinanced or refunded, and
     the Average Life of such new Indebtedness is at least equal to the
     remaining Average Life of the Indebtedness to be refinanced or refunded and
     (c) such new Indebtedness is Incurred by Steel Dynamics or a Subsidiary
     Guarantor or by the Restricted Subsidiary who is the obligor on the
     Indebtedness to be refinanced or refunded;

          (4) Indebtedness of Steel Dynamics, to the extent the net proceeds

     defease the Notes as described under "Defeasance";

          (5) Guarantees of the Notes and Guarantees of Indebtedness of Steel
     Dynamics or any Subsidiary Guarantor by any Restricted Subsidiary provided
     the Guarantee of such Indebtedness is permitted by and made in accordance
     with the "Limitation on Issuance of Guarantees by Restricted Subsidiaries"
     covenant;

          (6) Indebtedness of Steel Dynamics related to the Columbia City
     mini-mill in an aggregate principal amount outstanding at any time not to
     exceed $20 million;

          (7) Indebtedness of Steel Dynamics or any Subsidiary Guarantor
     Incurred for the purpose of financing all or any part of the purchase price
     or cost of construction or improvement of property, plant or equipment used
     in the business of Steel Dynamics or any Subsidiary Guarantor, in an
     aggregate principal amount outstanding at any time (together with
     refinancings thereof) not to exceed $20 million; or

          (8) Indebtedness of Steel Dynamics or any Restricted Subsidiary (in
     addition to Indebtedness permitted under clauses (1) through (7) above) in
     an aggregate principal amount outstanding at any

                                        41


     time (together with refinancings thereof) not to exceed $25 million, less
     any amount of such Indebtedness permanently repaid as provided under the
     "Limitation on Asset Sales" covenant.

     (b) Notwithstanding any other provision of this "Limitation on
Indebtedness" covenant, the maximum amount of Indebtedness that may be Incurred
pursuant to this "Limitation on Indebtedness" covenant will not be deemed to be
exceeded, with respect to any outstanding Indebtedness due solely to the result
of fluctuations in the exchange rates of currencies.

     (c) For purposes of determining any particular amount of Indebtedness under
this "Limitation on Indebtedness" covenant, (x) Indebtedness Incurred under the
Credit Agreement on or prior to the Closing Date shall be treated as Incurred
pursuant to clause (1) of the second paragraph of clause (a) of this "Limitation
on Indebtedness" covenant, (y) Guarantees, Liens or obligations with respect to
letters of credit supporting Indebtedness otherwise included in the
determination of such particular amount shall not be included and (z) any Liens
granted pursuant to the equal and ratable provisions referred to in the
"Limitation on Liens" covenant shall not be treated as Indebtedness. For
purposes of determining compliance with this "Limitation on Indebtedness"
covenant, in the event that an item of Indebtedness meets the criteria of more
than one of the types of Indebtedness described above (other than Indebtedness
referred to in clause (x) of the preceding sentence), including under the first
paragraph of part (a), Steel Dynamics, in its sole discretion, shall classify,
and from time to time may reclassify, such item of Indebtedness.

     (d) Steel Dynamics will not, and will not permit any Subsidiary Guarantor
to, Incur any Indebtedness if such Indebtedness is subordinate in right of
payment to any other Indebtedness unless such Indebtedness is also subordinate
in right of payment to the Notes, in the case of Steel Dynamics, or the Notes
Guarantee, in the case of a Subsidiary Guarantee, to the same extent.

     LIMITATION ON RESTRICTED PAYMENTS

     provided that the encumbrances and restrictions in any such extensions,
     refinancings, renewals or replacements taken as a whole are no less
     favorable in any material respect to the Holders than those encumbrances or
     restrictions that are then in effect and that are being extended,
     refinanced, renewed or replaced;

          (2) existing under or by reason of applicable law;

          (3) existing with respect to any Person or the property or assets of

     Person or the property or assets of any Person other than such Person or

             (C) arising or agreed to in the ordinary course of business, not
        relating to any Indebtedness, and that do not, individually or in the
        aggregate, detract from the value of property or assets of Steel
        Dynamics or any Restricted Subsidiary in any manner material to Steel
        Dynamics or any Restricted Subsidiary; or

          (5) with respect to a Restricted Subsidiary and imposed pursuant to an

Affecting Restricted Subsidiaries" covenant shall prevent Steel Dynamics or any
Restricted Subsidiary from (1) creating, incurring, assuming or suffering to
exist any Liens otherwise permitted in the "Limitation on Liens" covenant or (2)
restricting the sale or other disposition of property or assets of Steel

     Restricted Subsidiary would no longer constitute a Restricted Subsidiary
     and any Investment in such Person remaining after giving effect to such

holder) of 5% or more of any class of Capital Stock of Steel Dynamics or with
any Affiliate of Steel Dynamics or any Restricted Subsidiary, except upon fair
and reasonable terms no less favorable to Steel Dynamics or such Restricted
Subsidiary than could be obtained, at the time of such transaction or, if such
transaction is pursuant to a written agreement, at the time of the execution of
the agreement providing therefor, in a comparable arm's-length transaction with
a Person that is not such a holder or an Affiliate.

     The foregoing limitation does not limit, and shall not apply to:

     such transactions are in the ordinary course of Steel Dynamics' or such
     Restricted Subsidiaries' business, consistent with past practice and on an
     arm's length basis.

properties of any character, or any shares of Capital Stock or Indebtedness of
any Restricted Subsidiary, without making effective provision for all of the

     escrow account or similar arrangement to be applied for such purpose; or

          (9) Permitted Liens.

    LIMITATION ON SALE-LEASEBACK TRANSACTIONS

Dynamics or any of its Restricted Subsidiaries from one or more Asset Sales
occurring on or after the Closing Date in any period of 12 consecutive months
exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of the
date closest to the commencement of such 12-month period for which a

        case owing to a Person other than Steel Dynamics or any Affiliate of
        Steel Dynamics, or

             (B) invest an equal amount, or the amount not so applied pursuant
        to clause (A) (or enter into a definitive agreement committing to so
        invest within 12 months after the date of such agreement), in
        Replacement Assets, and

          (2) apply (no later than the end of the 12-month period referred to in
     clause (1)) such excess Net Cash Proceeds (to the extent not applied
     pursuant to clause (1)) as provided in the following paragraphs of this
     "Limitation on Asset Sales" covenant.

The amount of such excess Net Cash Proceeds required to be applied (or to be
committed to be applied) during such 12-month period as set forth in clause (1)
of the preceding sentence and not applied as so required by the end of such
period shall constitute "Excess Proceeds."

     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, Steel Dynamics
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders (and if required by the terms
of any Indebtedness that is pari passu with the Notes or the Note Guarantees
("Pari Passu Indebtedness"), from the holders of such Pari Passu Indebtedness)
on a pro rata basis an aggregate principal amount of Notes (and Pari Passu
Indebtedness) equal to the Excess Proceeds on such date, at a purchase price
equal to 100% of their principal amount, plus, in each case, accrued interest
(if any) to the Payment Date.

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 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 Notes) required by the foregoing covenant (as well as
may be contained in other securities of Steel Dynamics which might be
outstanding at the time).

     The above covenant requiring Steel Dynamics to repurchase the Notes will,
unless consents are obtained, require Steel Dynamics to repay all indebtedness
then outstanding which by its terms would prohibit such Note repurchase, either
prior to or concurrently with such 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 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 Notes validly tendered and not withdrawn in
such offer to purchase.

SEC REPORTS AND REPORTS TO HOLDERS

     Whether or not Steel Dynamics is then required to file reports with the
SEC, Steel Dynamics shall file with the SEC all such reports and other
information as it would be required to file with the SEC by Section 13(a) or
15(d) under the Securities Exchange Act of 1934 if it were subject thereto.
Steel Dynamics shall supply the Trustee and each Holder who so requests or shall
supply to the Trustee for forwarding to each such Holder, without cost to such
Holder, copies of such reports and other information.

EVENTS OF DEFAULT

     The following events will be defined as "Events of Default" in the
Indenture:

          (a) default in the payment of principal of (or premium, if any, on)
     any Note when the same becomes due and payable at maturity, upon
     acceleration, redemption or otherwise;

          (b) default in the payment of interest on any Note when the same
     becomes due and payable, and such default continues for a period of 30
     days;

                                        49


          (c) default in the performance or breach of the provisions of the
     Indenture applicable to mergers, consolidations and transfers of all or
     substantially all of the assets of Steel Dynamics and the Subsidiary
     Guarantors or the failure by Steel Dynamics to make or consummate an Offer
     to Purchase in accordance with the "Limitation on Asset Sales" or
     "Repurchase of Notes upon a Change of Control" covenant;

          (d) Steel Dynamics or any Subsidiary Guarantor defaults in the
     performance of or breaches any other covenant or agreement in the Indenture
     or under the Notes (other than a default specified in clause (a), (b) or
     (c) above) and such default or breach continues for a period of 30
     consecutive days after written notice by the Trustee or the Holders of 25%
     or more in aggregate principal amount of the Notes;

          (e) there occurs with respect to any issue or issues of Indebtedness
     of Steel Dynamics, any Subsidiary Guarantor or any Significant Subsidiary
     having an outstanding principal amount of $10 million or more in the
     aggregate for all such issues of all such Persons, whether such
     Indebtedness now exists or shall hereafter be created, (I) an event of
     default that has caused the holder thereof to declare such Indebtedness to
     be due and payable prior to its Stated Maturity and such Indebtedness has
     not been discharged in full or such acceleration has not been rescinded or
     annulled within 30 days of such acceleration and/or (II) the failure to
     make a principal payment at the final (but not any interim) fixed maturity
     and such defaulted payment shall not have been made, waived or extended
     within 30 days of such payment default;

          (f) any final judgment or order (not covered by insurance) for the
     payment of money in excess of $10 million in the aggregate for all such
     final judgments or orders against all such Persons (treating any
     deductibles, self-insurance or retention as not so covered) shall be
     rendered against Steel Dynamics, any Subsidiary Guarantor or any
     Significant Subsidiary and shall not be paid or discharged, and there shall
     be any period of 60 consecutive days following entry of the final judgment
     or order that causes the aggregate amount for all such final judgments or
     orders outstanding and not paid or discharged against all such Persons to
     exceed $10 million during which a stay of enforcement of such final
     judgment or order, by reason of a pending appeal or otherwise, shall not be
     in effect;

          (g) a court having jurisdiction in the premises enters a decree or
     order for (A) relief in respect of Steel Dynamics, any Subsidiary Guarantor
     or any Significant Subsidiary in an involuntary case under any applicable
     bankruptcy, insolvency or other similar law now or hereafter in effect, (B)
     appointment of a receiver, liquidator, assignee, custodian, trustee,
     sequestrator or similar official of Steel Dynamics, any Subsidiary
     Guarantor or any Significant Subsidiary or for all or substantially all of
     the property and assets of Steel Dynamics, any Subsidiary Guarantor or any
     Significant Subsidiary or (C) the winding-up or liquidation of the affairs
     of Steel Dynamics, any Subsidiary Guarantor or any Significant Subsidiary
     and, in each case, such decree or order shall remain unstayed and in effect
     for a period of 60 consecutive days;

          (h) Steel Dynamics, any Subsidiary Guarantor or any Significant
     Subsidiary (A) commences a voluntary case under any applicable bankruptcy,
     insolvency or other similar law now or hereafter in effect, or consents to
     the entry of an order for relief in an involuntary case under any such law,
     (B) consents to the appointment of or taking possession by a receiver,
     liquidator, assignee, custodian, trustee, sequestrator or similar official
     of Steel Dynamics, any Subsidiary Guarantor or any Significant Subsidiary
     or for all or substantially all of the property and assets of Steel
     Dynamics, any Subsidiary Guarantor or any Significant Subsidiary or (C)
     effects any general assignment for the benefit of creditors; or

          (i) any Subsidiary Guarantor repudiates its obligations under its Note
     Guarantee or, except as permitted by the Indenture, any Note Guarantee is
     determined to be unenforceable or invalid or shall for any reason cease to
     be in full force and effect.

     If an Event of Default (other than an Event of Default specified in clause
(g) or (h) 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

                                        50


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 (e) 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 (e) 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 (g) or (h) 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.

     Officers 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 Restricted Subsidiaries and Steel
Dynamics' and its Restricted 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.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     Steel Dynamics will not consolidate with, merge with or into, or sell,
convey, transfer, lease or otherwise dispose of all or substantially all of its
property and assets (as an entirety or substantially an entirety in one

                                        51


transaction or a series of related transactions) to, any Person or permit any
Person to merge with or into it unless:

          (1) it shall be the continuing Person, or the Person (if other than
     it) formed by such consolidation or into which it is merged or that
     acquired or leased such property and assets (the "Surviving Person"), shall
     be a corporation organized and validly existing under the laws of the
     United States of America or any jurisdiction thereof and shall expressly
     assume, by a supplemental indenture, executed and delivered to the Trustee,
     all of Steel Dynamics' obligations under the Indenture and the Notes;

          (2) immediately after giving effect to such transaction, no Default or
     Event of Default shall have occurred and be continuing;

          (3) immediately after giving effect to such transaction on a pro forma
     basis, Steel Dynamics or the Surviving Person, as the case may be, shall
     have a Consolidated Net Worth equal to or greater than the Consolidated Net
     Worth of Steel Dynamics immediately prior to such transaction;

          (4) immediately after giving effect to such transaction on a pro forma
     basis Steel Dynamics, or the Surviving Person, as the case may be, could
     Incur at least $1.00 of Indebtedness under the first paragraph of the
     "Limitation on Indebtedness" covenant; provided that this clause (4) shall
     not apply to a consolidation, merger or sale of all (but not less than all)
     of the assets of Steel Dynamics if all Liens and Indebtedness of Steel
     Dynamics or the Surviving Person, as the case may be, and its Restricted
     Subsidiaries outstanding immediately after such transaction would have been
     permitted (and all such Liens and Indebtedness, other than Liens and
     Indebtedness of Steel Dynamics and its Restricted Subsidiaries outstanding
     immediately prior to the transaction, shall be deemed to have been
     Incurred) for all purposes of the Indenture;

          (5) it delivers to the Trustee an Officers' Certificate (attaching the
     arithmetic computations to demonstrate compliance with clauses (3) and (4))
     and Opinion of Counsel, in each case stating that such consolidation,
     merger or transfer and such supplemental indenture complies with this
     provision and that all conditions precedent provided for herein relating to
     such transaction have been complied with; and

          (6) each Subsidiary Guarantor, unless such Subsidiary Guarantor is the
     Person with which Steel Dynamics has entered into a transaction under this
     "Consolidation, Merger and Sale of Assets" section, shall have by amendment
     to its Note Guarantee confirmed that its Note Guarantee shall apply to the
     obligations of Steel Dynamics or the Surviving Person in accordance with
     the Notes and the Indenture;

provided, however, that clauses (3) and (4) above do not apply if, in the good
faith determination of the Board of Directors of Steel Dynamics, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of Steel Dynamics and
any such transaction shall not have as one of its purposes the evasion of the
foregoing limitations.

     The Surviving Person will succeed to, and except in the case of a lease be
substituted for, Steel Dynamics under the Indenture and the Notes.

     Each Subsidiary Guarantor (other than any Subsidiary Guarantor whose Note
Guarantee is to be released in accordance with the terms of its Note Guarantee
and the Indenture in connection with any transaction complying with the
provisions of "-- Limitation on Asset Sales") will not, and Steel Dynamics will
not cause or permit any Subsidiary Guarantor to, consolidate with or merge with
or into any Person other than Steel Dynamics or any other Subsidiary Guarantor
unless:

          (1) such Subsidiary Guarantor is the surviving corporation or the
     Person formed by or surviving any such consolidation or merger (if other
     than the Subsidiary Guarantor) is a corporation organized and existing
     under the laws of the United States or any State thereof or the District of
     Columbia and such Person assumes by supplemental indenture all of the
     obligations of the Subsidiary Guarantor on its Note Guarantee;

                                        52


          (2) immediately after giving effect to such transaction, no Default or
     Event of Default shall have occurred and be continuing; and

          (3) immediately after giving effect to such transaction and the use of
     any net proceeds therefrom on a pro forma basis, Steel Dynamics could
     satisfy the provisions of clause (3) of the first paragraph of this
     covenant.

     Any merger or consolidation of a Subsidiary Guarantor with and into Steel
Dynamics (with Steel Dynamics being the surviving entity) or another Subsidiary
Guarantor need only comply with clause (5) of the first paragraph of this
covenant.

     The successor Subsidiary Guarantor will succeed to, and except in the case
of a lease be substituted for, such Subsidiary Guarantor under the Indenture and
such Subsidiary Guarantor's Note Guarantee.

DEFEASANCE

     Defeasance and Discharge.  The Indenture will provide that Steel Dynamics
will be deemed to have paid and will be discharged from any and all obligations
in respect of the Notes on the 123rd day after the deposit referred to below,
and the provisions of the Indenture will no longer be in effect with respect to
the Notes (except for, among other matters, certain obligations to register the
transfer or exchange of the Notes, to replace stolen, lost or mutilated 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 Notes (i) on the Stated Maturity of such payments
     in accordance with the terms of the Indenture and the Notes or (ii) on any
     earlier Redemption Date pursuant to the terms of the Indenture and the
     Notes; provided that Steel Dynamics has provided the Trustee with
     irrevocable instructions to redeem all of the outstanding 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 Section 547 of the United States Bankruptcy Code
     or Section 15 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 123rd 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 Notes are listed on a national securities
     exchange, Steel Dynamics has delivered to the Trustee an Opinion of Counsel
     to the effect that the 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 will provide that the provisions of the Indenture will no
longer be in effect with respect to clauses (3) and (4) under

                                        53


"Consolidation, Merger and Sale of Assets" and all the covenants described
herein under "Covenants," clause (c) under "Events of Default" with respect to
such clauses (3) and (4) under "Consolidation, Merger and Sale of Assets,"
clause (d) under "Events of Default" with respect to such other covenants and
clauses (e) and (f) 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 Notes (i) on the Stated Maturity of such payments in
accordance with the terms of the Indenture and the Notes or (ii) on any earlier
Redemption Date pursuant to the terms of the Indenture and the Notes; provided
that Steel Dynamics has provided the Trustee with irrevocable instructions to
redeem all of the outstanding 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 Notes as described in the
immediately preceding paragraph and the 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 Notes at the time of their Stated
Maturity but may not be sufficient to pay amounts due on the 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
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" or "Limitation on Issuances of Guarantees by Restricted
     Subsidiaries";

          (3) comply with any requirements of the SEC in connection with the
     qualification of the Indenture under the Trust Indenture Act;

          (4) evidence and provide for the acceptance of appointment by a
     successor Trustee; or

          (5) 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 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 Note,

          (2) reduce the principal amount of, or premium, if any, or interest
     on, any Note,

          (3) change the optional redemption dates or optional redemption prices
     of the Notes from that stated under the caption "Optional Redemption,"

          (4) change the place or currency of payment of principal of, or
     premium, if any, or interest on, any Note,

                                        54


          (5) impair the right to institute suit for the enforcement of any
     payment on or after the Stated Maturity (or, in the case of a redemption,
     on or after the Redemption Date) of any Note,

          (6) waive a default in the payment of principal of, premium, if any,
     or interest on the Notes,

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

          (8) amend, change or modify the obligation of Steel Dynamics to make
     and consummate an Offer to Purchase under the "Limitation on Asset Sales"
     after the obligation to make such Offer to Purchase has arisen or the
     obligation of Steel Dynamics to make and consummate an Offer to Purchase
     under the "Repurchase of Notes upon a Change of Control" covenant after a
     Change of Control has occurred, including, in each case, amending, changing
     or modifying any definition relating thereto, or

          (9) reduce the percentage or aggregate principal amount of outstanding
     Notes the consent of whose Holders is necessary for waiver of compliance
     with certain provisions of the Indenture or for waiver of certain defaults.

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 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 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 Notes, waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the 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 certificates representing the Notes will be issued in fully registered
form without interest coupons. Notes sold in offshore transactions in reliance
on Regulation S under the Securities Act will initially be represented by one or
more permanent global Notes in definitive, fully registered form without
interest coupons (each a "Regulation S Global Note") and will be deposited with
the Trustee as custodian for, and registered in the name of a nominee of, The
Depository Trust Company ("DTC") for the accounts of Euroclear and Clearstream.
Prior to the 40th day after the Closing Date, beneficial interests in the
Regulation S Global Notes may only be held through Euroclear or Clearstream, and
any resale or transfer of such interests to U.S. persons shall not be permitted
during such period unless such resale or transfer is made pursuant to Rule 144A
or Regulation S.

     Notes sold in reliance on Rule 144A will be represented by one or more
permanent global Notes in definitive, fully registered form without interest
coupons (each a "Restricted Global Note"; and together with

                                        55


the Regulation S Global Notes, the "Global Notes") and will be deposited with
the Trustee as custodian for, and registered in the name of a nominee of, DTC.

     Each Global Note (and any Notes issued for exchange therefor) will be
subject to certain restrictions on transfer set forth therein as described under
"Transfer Restrictions."

     Notes transferred to institutional "accredited investors" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act (an "Institutional
Accredited Investor") who are not qualified institutional buyers ("Non-Global
Purchasers") will be in registered form without interest coupons ("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. For a description of the restrictions on the transfer
of Certificated Notes, see "Transfer Restrictions."

     Ownership of beneficial interests in a Global Note will be limited to
persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in a Global
Note will be shown on, and the transfer of that ownership will be effected only
through, records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). Qualified institutional buyers may hold their
interests in a Restricted Global Note directly through DTC if they are
participants in such system, or indirectly through organizations which are
participants in such system.

     Investors may hold their interests in a Regulation S Global Note directly
through Euroclear or Clearstream, if they are participants in such systems, or
indirectly through organizations that are participants in such system. On or
after the 40th day following the Closing Date, investors may also hold such
interests through organizations other than Euroclear or Clearstream that are
participants in the DTC system. Euroclear or Clearstream will hold interests in
the Regulation S Global Notes on behalf of their participants through DTC.

     So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture and, if applicable, those of Euroclear and Clearstream.

     Payments of the principal of, and interest on, a Global Note will be made
to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither Steel Dynamics, the Trustee nor any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Steel Dynamics expects that DTC or its nominee, upon receipt of any payment
of principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or its nominee. Steel Dynamics also expects that payments by participants to
owners of beneficial interests in such Global Note held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the names of nominees for such customers. Such payments will be the
responsibility of such participants.

     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds. Transfers
between participants in Euroclear and Clearstream will be effected in the
ordinary way in accordance with their respective rules and operating procedures.

     Steel Dynamics expects that DTC will take any action permitted to be taken
by a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more participants to whose
account the DTC interests in a Global Note is credited and only in respect of
such portion of the aggregate principal amount of Notes as to which such
participant or participants has or have

                                        56


given such direction. However, if there is an Event of Default under the Notes,
DTC will exchange the applicable Global Note for Certificated Notes, which it
will distribute to its participants and which may be legended as set forth under
the heading "Transfer Restrictions."

     Steel Dynamics understands that: DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of
certificates. Indirect access to the DTC system is available to others such as
banks, brokers, dealers and trust companies and certain other organizations that
clear through or maintain a custodial relationship with a participant, either
directly or indirectly ("indirect participants").

     Although DTC, Euroclear and Clearstream are expected to follow the
foregoing procedures in order to facilitate transfers of interests in a Global
Note among participants of DTC, Euroclear and Clearstream, they are under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Neither Steel Dynamics nor the
Trustee will have any responsibility for the performance by DTC, Euroclear or
Clearstream or their respective participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.

     If DTC is at any time unwilling or unable to continue as a depositary for
the Global Notes and a successor depositary is not appointed by Steel Dynamics
within 90 days, Steel Dynamics will issue Certificated Notes, which may bear the
legend referred to under "Transfer Restrictions," in exchange for the Global
Notes. Holders of an interest in a Global Note may receive Certificated Notes,
which may bear the legend referred to under "Transfer Restrictions," in
accordance with the DTC's rules and procedures in addition to those provided for
under the Indenture.

occurrence of the contingency giving rise to the obligation, provided

     with original issue discount is the face amount of such Indebtedness less
     the remaining unamortized portion of the original issue discount of such
     Indebtedness at such time as determined in conformity with GAAP,

          (B) that money borrowed and set aside at the time of the Incurrence of
     any Indebtedness in order to prefund the payment of the interest on such
     Indebtedness shall not be deemed to be "Indebtedness" so long as such money
     is held to secure the payment of such interest and

                UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following summary describes certain United States tax consequences of
the acquisition, ownership and disposition of the notes. The summary is based on
the Internal Revenue Code of 1986, as amended (the "Code"), and United States
Treasury regulations issued thereunder, Internal Revenue Service rulings and
pronouncements and judicial decisions as of the date hereof, all of which may be
repealed, revoked or modified so as to result in United States tax consequences
different from those described below. Such changes could be applied
retroactively in a manner that could adversely affect you. In addition, the
authorities on which this summary is based are subject to various
interpretations. It is therefore possible that the consequences of the
acquisition, ownership and disposition of the notes may differ from the
treatment described below.

     The tax treatment of a holder of the notes may vary depending upon the
particular situation of the holder. This summary is limited to initial
beneficial investors that purchase the old notes for cash upon their original
issuance at the price set forth on the cover of this memorandum, and is limited
to investors who hold the notes as capital assets within the meaning of Section
1221 of the Code. This summary does not deal with holders that may be subject to
special tax rules (including, but not limited to, banks, insurance companies,
tax-exempt organizations, financial institutions, dealers in securities or
currencies, partnerships or other flow-through entities classified as
partnerships for U.S. federal income tax purposes, persons subject to the
alternative minimum tax (as defined below), U.S. Holders whose functional
currency is not the U.S. dollar, certain U.S. expatriates, Non-United States
Holders (as defined below) that are subject to a tax treaty with the United
States, or holders who will hold the notes as a hedge against currency risks or
as part of a straddle, synthetic security, conversion transaction or other
integrated investment comprised of the notes and one or more other investments).

     This summary is for general information only and does not address all
aspects of United States taxation that may be relevant to holders of the notes
in light of their particular circumstances, and it does not address any tax
consequences arising under the laws of any state, local or foreign taxing
jurisdiction. Prospective holders should consult their own tax advisors as to
the particular tax consequences to them of acquiring, holding or disposing of
the notes.

     As used herein, a "United States Holder" of a note means a beneficial owner
of a note that, for U.S. federal income tax purposes, is a citizen or resident
of the United States; a corporation or other entity taxable as a corporation for
U.S. federal income tax purposes, created or organized in or under the laws of
the United States or of any state of the United States or the District of
Columbia; an estate the income of which is subject to United States federal
income taxation regardless of its source; or a trust if (1) a U.S. court is able
to exercise primary supervision over the administration of the trust and (2) one
or more U.S. persons have the authority to control all substantial decisions of
the trust.

     If a partnership is a beneficial owner of a note, the U.S. tax treatment of
a partner in the partnership will generally depend upon the status of the
partner and the activities of the partnership. A beneficial owner of old notes
or Exchange Notes that is a partnership, and partners in such a partnership,
should consult their tax advisors about the U.S. Federal income tax consequences
of the acquisition, ownership and disposition of the old notes and Exchange
Notes.

TAX CONSEQUENCES TO UNITED STATES HOLDERS

  INTEREST

     Except as set forth below, interest on a note generally will be taxable to
a United States Holder as ordinary income from domestic sources at the time it
is paid or accrued, or is actually or constructively received, in accordance
with the United States Holder's method of accounting for tax purposes.

     Our failure to consummate the Exchange Offer or to file or cause to be
declared effective the Shelf Registration Statement as described under
"Description of Notes -- Registration Rights" will cause additional interest to
accrue on the notes in the manner described therein. According to U.S. Treasury
regulations, the possibility of a change in the interest rate will not affect
the amount of interest income recognized by a United States Holder (or the
timing of such recognition) if the likelihood of the change, as of the date the

                                        71


notes are issued, is remote. We believe that the likelihood of a change in the
interest rate on the notes is remote and do not intend to treat the possibility
of a change in the interest rate as affecting the yield to maturity of any note.
In the unlikely event that the interest rate on the notes is increased, then
such increased interest should be treated as ordinary income for U.S. federal
income tax purposes at the time it accrues or is received in accordance with the
United States Holder's regular method of tax accounting. Our determination that
there is a remote likelihood of a change in the interest rate on the notes is
binding on each United States Holder unless the holder explicitly discloses in
the manner required by applicable U.S. Treasury regulations that its
determination is different from ours. It is possible, however, that the Internal
Revenue Service may take a different position and treat the additional interest
income as original issue discount, includable by a United States Holder in
income as such interest accrues, in advance of receipt of any cash payment
thereof, or it may treat as interest income all or a portion of any gain
recognized on the disposition of an old note or Exchange Note. If, as
anticipated, the issue price of the notes will equal their stated principal
amount, and because the likelihood of a change in the interest rate is remote,
we do not anticipate that the notes will be issued with original issue discount.

     The notes may be redeemed prior to their stated maturity at our option or
at the option of the holders upon certain circumstances or automatically upon
the occurrence of certain events. We believe that none of such redemption rights
or obligations are more likely than not to occur, and, thus, under applicable
Treasury regulations, none of such redemption rights or obligations should
affect the yield of the notes.

  SALE, EXCHANGE AND RETIREMENT OF NOTES OR EXCHANGE NOTES

     Upon the sale, exchange, redemption, retirement or other disposition of a
note, a United States Holder generally will recognize gain or loss equal to the
difference between the amount realized (the sum of cash plus the fair market
value of all other property received), except to the extent the sales proceeds
are attributable to accrued but unpaid interest, and such holder's adjusted tax
basis in the note. A United States Holder's adjusted tax basis in a note will,
in general, be equal to the initial purchase price the holder paid for the
notes, plus original issue discount, if any, previously included in income, less
any cash payment received in respect of such original issue discount, and
further reduced by any principal payments received by such United States Holder.
In general, except to the extent the gain or loss is attributable to accrued but
unpaid stated interest, such gain or loss will be capital gain or loss. Such
capital gain or loss generally will be long-term capital gain or loss if the
holding period of the note exceeds one year at the time of the disposition.
Certain noncorporate taxpayers (including individuals) are eligible for
preferential rates of taxation of such long-term capital gain. The deductibility
of capital losses is subject to limitations.

     The exchange of an old note by a United States Holder for a Exchange Note
pursuant to the Exchange Offer should not constitute a taxable exchange. A
United States Holder will have the same tax basis and holding period in the
Exchange Note as it did in the old note.

  BACKUP WITHHOLDING AND INFORMATION REPORTING

     Information returns will be filed with the Internal Revenue Service in
connection with payments on the notes and the proceeds from a sale or other
disposition of the notes. A United States Holder will be subject to United
States backup withholding tax on these payments if the holder fails to provide
its taxpayer identification number to the paying agent and comply with certain
certification procedures or otherwise establish an exemption from backup
withholding. United States Holders should consult their own tax advisor
regarding their qualification for an exemption from backup withholding and the
procedures for obtaining such an exemption, if applicable. The amount of any
backup withholding from a payment will be allowed as a credit against a United
States Holder's U.S. federal income tax liability and may entitle the holder to
a refund, provided that the required information is furnished to the Internal
Revenue Service.

TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS

     A "Non-United States Holder" of a note means a beneficial owner of a note
that, for U.S. federal income tax purposes, is not a United States Holder.

                                        72


  WITHHOLDING TAXES

     Generally, payments of principal and interest (including OID), on the notes
will not be subject to United States withholding taxes provided that:

     - the Non-United States Holder does not actually or constructively own 10
       percent or more of the total combined voting power of all classes of
       stock of the Company entitled to vote,

     - the Non-United States Holder is not a controlled foreign corporation that
       is related to the Company through its stock ownership,

     - the Non-United States Holder is not a bank described in Section
       881(c)(3)(A) of the Code, and

     - either (A) the Non-United States Holder provides its name and address on
       an IRS Form W-8BEN (or substitute form), and certifies, under penalties
       of perjury, that it is not a United States Holder or (B) it holds its
       notes through certain foreign intermediaries and it satisfies the
       certification requirements of applicable U.S. Treasury regulations.
       Special certification rules apply to certain Non-United States Holders
       that are entities rather than individuals.

     If a Non-United States Holder cannot satisfy the requirements described
above, payments of interest (including OID) made to the Non-United States Holder
will be subject to U.S. federal withholding tax, unless the Non-United States
Holder provides the Company with a properly executed (1) IRS Form W-8BEN (or
substitute form) claiming an exemption from or a reduction in the rate of
withholding under the benefit of an applicable tax treaty or (2) IRS Form W-8ECI
(or successor form) stating that interest paid on the notes is not subject to
withholding because it is effectively connected with the conduct of Non-United
States Holder's trade or business in the United States.

  SALE OR REDEMPTION OF NOTES

     The exchange of an old note by a Non-United States Holder for a Exchange
Note pursuant to the Exchange Offer should not constitute a taxable exchange. A
Non-United States Holder will have the same tax basis and holding period in the
Exchange Note as it did in the old note.

     If a Non-United States Holder meeting the United States certification
requirements as set forth above sells or otherwise disposes of a note or such
note is redeemed, the Non-United States Holder generally will not be subject to
United States federal income tax on any gain unless one of the following
applies:

     - The gain is effectively connected with a trade or business that the
       Non-United States Holder conducts in the United States.

     - The Non-United States Holder is an individual, is present in the U.S. for
       at least 183 days during the year in which the holder disposes of the
       notes and certain other conditions are satisfied.

     - The gain represents accrued interest, in which case the rules for
       interest would apply.

  EFFECTIVELY CONNECTED INCOME

     If a Non-United States Holder of a note is engaged in a trade or business
in the United States, and if interest on the note is effectively connected with
the conduct of this trade or business, the Non-United States Holder, although
exempt from the withholding tax discussed above, will generally be taxed in the
same manner as a United States Holder (see "Tax Consequences to United States
Holders" above), except that the holder will be required to provide to the
Company a properly executed IRS Form W-8ECI (or successor form) in order to
claim an exemption from withholding tax.

     If the Non-United States Holder is a corporation, it may also be subject to
"branch profits tax" on its earnings that are effectively connected with the
holder's U.S. trade or business, including earnings from the note. This tax is
30%, but may be reduced or eliminated by an applicable tax treaty.

                                        73


  INFORMATION REPORTING AND BACKUP WITHHOLDING

     Interest payments made to Non-United States Holders will generally be
reported to the IRS and to each Non-United States Holder on Form 1042-S.
However, this reporting does not apply if one of the following conditions
applies:

     - The Non-United States Holder holds its notes directly through a qualified
       intermediary and the applicable procedures are complied with.

     - The Non-United States Holder files Form W-8ECI.

     Information reporting and backup withholding apply to Non-United States
Holders as follows:

     - Principal and interest payments received will generally be exempt from
       the information reporting and backup withholding if the holder is a
       Non-United States Holder exempt from withholding on interest and
       satisfies the United States certification requirements described above.
       The exemption does not apply if the withholding agent or an intermediary
       knows or has reason to know that the holder should be subject to the
       usual information reporting or backup withholding rules.

     - In general, a Non-United States Holder will not be subject to information
       reporting and backup withholding on the sale proceeds received on sale of
       a note. However, sale proceeds received on a sale of a Non-United States
       Holder's notes through a broker may be subject to information reporting
       and/or backup withholding may apply if the Non-United States Holder uses
       the United States office of a broker, and information reporting (but not
       backup withholding) may apply if it uses the foreign office of a broker
       that has certain connections to the United States.

                                        74


                              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.

                                 LEGAL MATTERS

     The validity of the issuance of the Exchange Notes will be passed upon for
us by Barrett & McNagny LLP, Fort Wayne, Indiana.

                                    EXPERTS

     Ernst & Young LLP, independent auditors, have audited our consolidated
financial statements included in our Annual Report on Form 10-K for the year

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     As permitted by Chapter 37 of the Indiana Business Corporation Law, Article
IX of our Amended and Restated Articles of Incorporation provides that we shall
indemnify a director or officer against liability, including expenses and costs
of defense, incurred in any proceeding, if that individual was made a party 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 reasonably belief, in
connection with the individual's "official capacity," that the conduct was in
our beset 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.

     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 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.

     The indemnification provisions set forth in Article IX of the Amended and
Restated Articles of Incorporation, as well as the authority vested in our board
of directors by Chapter 37 of the Business Corporation Law to grant
indemnification beyond that which is described in Article IX, may be
sufficiently broad to provide indemnification of our directors and officers for
liabilities arising under the Securities Act.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our 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

                                       II-1


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 and
officers which provides coverage for losses of directors and officers for
liabilities arising out of claims against such persons acting as our officers or
directors, or 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 Section 10(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;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) to not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference 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) For purposes of determining any liability under the Securities Act of
1933, each filing of the registrant's annual report pursuant to Section 13(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 Section 15(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.

     (c) 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.

                                       II-4


     (d) 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.

     (e) 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.

                                       II-5


                                   SIGNATURES
