    Pursuant to an agency agreement between NSM(Del) and NSM Cayman, NSM(Del)
will issue the Notes and pay amounts due thereunder solely as agent of NSM
Cayman. On the date of issue of the Old Securities (the "Issue Date"), the
Company deposited with the Collateral Agent (as defined) (i) the net proceeds of
the Offerings (as defined) (after the payment of certain fees and expenses, as
well as the prepayment of U.S.$50 million of existing indebtedness and U.S.$8.0
million of accrued interest payable to certain Thai financial institutions), and
(ii) the U.S.$18.5 million of cash proceeds from the Equity Investments (as
defined). Of such proceeds, an amount equal to the sum of the interest due on
the Senior Notes on the first three Interest Payment Dates (as defined), the
interest due on the Senior Subordinated Notes on the first two Interest Payment
Dates and the interest due on the Debentures on the first two Interest Payment
Dates was deposited in the Notes DSR Account (as defined) and the balance was
deposited in the Offshore Reserve Account (as defined). The interest due on the
Notes and Debentures on the first two Interest Payment Dates after the Issue
Date shall be paid from the Notes DSR Account. Thereafter, the Company shall at
all times be required to maintain a balance in the Notes DSR Account equal to
the next interest payment on the Senior Notes. Funds held in the Offshore
Reserve Account will be used to construct and start-up the Mill (including the
payment of approximately U.S.$102 million in accounts payable), finance certain
operating expenses and, in certain limited circumstances, to pay interest on
Indebtedness owed by the Company to certain Thai financial institutions.
 
    If the Company achieves Profitable Operations (as defined) prior to December
31, 2001, certain amounts in the Offshore Reserve Account will be released to
the Company. If the Company fails to achieve Profitable Operations by December
31, 2001, the Company must apply any funds then remaining in the Offshore
Reserve Account (i) to tender for the Securities at 100% of the Accreted Value
(as defined) thereof at the date of redemption plus accrued and unpaid interest
and (ii) if there are funds remaining in such account after such tender, to
repay indebtedness to certain Thai financial institutions.
 
    The Senior Notes bear interest on the principal amount at maturity thereof
at a rate of 12% per annum, payable on February 1 and August 1 of each year,
commencing August 1, 1998. The Old Senior Notes were issued at a discount to
their principal amount at maturity. As a result, the stated rate of interest and
original issue discount represents a yield to maturity (based on the issue
price) on the Senior Notes of 14% (computed on a semi-annual bond equivalent
basis). The Senior Notes will mature on February 1, 2006. The Senior Notes will
not be redeemable at the option of the Note Issuers prior to February 1, 2002,
except that until February 1, 2001, the Note Issuers may redeem, at their
option, up to an aggregate of 35% of the aggregate principal amount at maturity
of the Senior Notes originally issued at the redemption price set forth herein
plus accrued interest to the date of redemption with the net proceeds of one or
more Public Equity Offerings (as defined) if at least $162 million principal
amount at maturity of the Senior Notes remains outstanding after each such
redemption. On or after February 1, 2002, the Senior Notes may be redeemed at
the option of the Note Issuers, in whole or in part, at the redemption prices
set forth herein. Upon a Change of Control (as defined), each holder of Senior
Notes will have the right to require the Note Issuers to purchase all or any
part of such holder's Senior Notes at a purchase price equal to 101% of the
Accreted Value thereof, plus accrued and unpaid interest, if any, to the date of
purchase.
 
    The Senior Subordinated Notes bear interest on the principal amount at
maturity thereof at a rate of 12.25% per annum, payable on February 1 and August
1 of each year, commencing August 1, 1998. The Old Senior Subordinated Notes
were issued at a discount to their principal amount at maturity. As a result,
the stated rate of interest and original issue discount will represent a yield
to maturity on the Senior Subordinated Notes of 15% (computed on a semi-annual
bond equivalent basis). The Senior Subordinated Notes will mature on February 1,
2008. The Senior Subordinated Notes will not be redeemable at the option of the
Note Issuers prior to February 1, 2003, except that until February 1, 2001, the
Note Issuers may redeem, at their option, up to an aggregate of 35% of the
aggregate principal amount at maturity of the Senior Subordinated Notes
originally issued at the redemption price set forth herein plus accrued interest
to the date of redemption with the net proceeds of one or more Public Equity
Offerings if at least $132 million principal amount at maturity of the Senior
Subordinated Notes remains outstanding after each such redemption. On or after
February 1, 2003, the Senior Subordinated Notes may be redeemed at the option of
the Note Issuers, in whole or in part, at the redemption prices set forth
herein. Upon a Change of Control, each holder of Senior Subordinated Notes will
have the right to require the Note Issuers to purchase all or any part of such
holder's Senior Subordinated Notes at a purchase price equal to 101% of the
Accreted Value thereof, plus accrued and unpaid interest, if any, to the date of
purchase.
 
    The Debentures bear interest on the principal amount at maturity thereof at
a rate of 12 3/4% per annum, payable on February 1 and August 1 of each year,
commencing August 1, 1998. The Old Debentures were issued at discount to there
principal amount at maturity. The Debentures will mature on February 1, 2009.
The Debentures will not be redeemable at the option of the Note Issuers prior to
February 1, 2003, except that until February 1, 2001, the Note Issuers may
redeem at their option, up to an aggregate of 35% of the aggregate principal
amount at maturity of the Debentures originally issued at the redemption price
set forth herein plus accrued interest to the date of redemption with a note
proceeds of one or more Public Equity offerings if at least $35 million
principal amount of maturity of the Debentures remains outstanding after each
such redemption. On or after February 1, 2003, the Debentures may be redeemed at
the option of the Note Issuers, in whole or in part, at the redemption prices
set forth herein. Upon a Change of Control, each holder of Debentures will have
the right to require the Note Issuers to purchase all or any part of such
holder's Debentures at a purchase price equal to 101% of the Accreted Value
thereof, plus accrued and unpaid interest, if any to the date of purchase.
 
    The Securities will bear original issue discount ("OID"), and the holders of
the Notes will be required to include such OID in gross income for U.S. federal
income tax purposes on a constant yield to maturity basis, in advance of the
receipt of the cash payments to which such income is attributable. See "Tax
Considerations."

be shown on, and transfers thereof will be effected only through, records
maintained in book-entry form by The Depository Trust Company ("DTC") and its
participants, including Morgan Guaranty Trust Company of New York, Brussels
Office, as operator of the Euroclear System (the "Euroclear Operator") and Cedel
Bank, societe anonyme ("Cedel"). Such beneficial interests in the Global
Securities are hereinafter referred to as "Book-Entry Interests."
 
    The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company and the Note Issuers under certain registration
rights agreements each dated as of March 12, 1998 (the "Notes Registration
Rights Agreements") each between the Company, the Note Issuers and Nat West
Capital Markets Limited as the initial purchaser of the Old Notes (the "Initial
Purchaser").
 
    The New Debentures are being offered hereunder in order to satisfy certain
obligations of the Company and the Debenture Issuers under the Debentures
Registration Rights Agreement dated as of March 12, 1998 (the "Debentures
Registration Rights Agreement" and collectively with the Notes Registration
Rights Agreement, the "Registration Rights Agreements") between the Company, the
Note Issuers and the Debenture purchasers.
 
    The Company and the Note Issuers are making the Exchange Offers in reliance
on the position of the staff of the Securities and Exchange Commission (the
"Commission") as set forth in certain no-action letters addressed to other
parties in other transactions. However, neither the Company nor the Note Issuers
have sought their own no-action letter and there can be no assurance that the
staff of the Commission will make a similar determination with respect to the
Exchange Offers as in such other circumstances. Based upon these interpretations
by the staff of the Commission, the Company and the Note Issuers believe that
New Securities issued pursuant to the Exchange Offers in exchange for Old
Securities may be offered for resale, resold and otherwise transferred by a
holder thereof other than (i) a broker-dealer who purchased such Old Securities
directly from the Company to resell pursuant to Rule 144A or any other available
exemption under the Securities Act or (ii) a person that is an "affiliate" (as
defined in Rule 405 of the Securities Act) of the Company without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that such New Securities are acquired in the ordinary course of such
holder's business and that such holder is not participating, and has no
arrangement or understanding with any person to participate, in the distribution
of such New Securities. Holders of the Old Securities accepting the Exchange
Offers will represent to the Company in the Letter of Transmittal that such
conditions have been met. Any holder who participates in the Exchange Offers for
the purpose of participating in a distribution of the New Securities may not
rely on the position of the staff of the Commission as set forth in these
no-action letters and would have to comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any secondary
resale transaction. A secondary resale transaction in the United States by a
holder who is using the Exchange Offers to participate in the distribution of
New Securities must be covered by a registration statement containing the
selling securityholder information required by Item 507 of Regulation S-K of the
Securities Act.
 
    Each broker-dealer (other than an "affiliate" of the Company) that receives
New Securities for its own account pursuant to the Exchange Offers must
acknowledge that it acquired the Old Securities as a result of market-making
activities or other trading activities and will deliver a prospectus in
connection with any resale of such New Securities. 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 New
Securities received in exchange for Old Notes where such Old Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. The Note Issuers have agreed that, for a period of 180 days
after the Expiration Date (as defined herein), it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution." Any broker-dealer who is an affiliate of the Note
Issuers may not rely on such no-action letters and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any secondary resale transaction. See "The Exchange Offers."
 
    The New Securities are new securities for which there is currently no
market. The Note Issuers presently does not intend to apply for listing of the
New Securities on any securities exchange or for quotation through the National
Association of Securities Dealers Automated Quotation System ("NASDAQ"). The
Company has been advised by the Initial Purchasers that, following completion of
the Exchange Offers, they presently intend to make a market in the New
Securities; however, the Initial Purchasers are not obligated to do so and any
market-making activities with respect to the New Securities may be discontinued
at any time without notice. There can be no assurance that an active public
market for the New Securities will develop.
 
    THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD SECURITIES ARE URGED TO READ THIS PROSPECTUS AND THE
RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER THEIR
OLD SECURITIES PURSUANT TO THE EXCHANGE OFFERS.
 
    Any Old Securities not tendered and accepted in the Exchange Offers will
remain outstanding and will be entitled to all the rights and preferences and
subject to the limitations applicable thereto under the applicable Indenture.
Following consummation of the Exchange Offers the holders of Old Securities will
continue to be subject to the existing restrictions upon transfer thereof and
the Company and the Note Issuers will have no further obligation to such holders
(other than the Initial Purchasers) to provide for the registration under the
Securities Act of the Old Securities held by them. To the extent that Old
Securities are tendered and accepted in the Exchange Offers, a holder's ability
to sell untendered Old Securities could be adversely affected. It is not
expected that an active market for the Old Securities will develop while they
are subject to restrictions on transfer. The Company will accept for exchange
any and all Old Securities that are validly tendered and not withdrawn on or
prior to 5:00 p.m., New York City time, on the date the Exchange Offers expire,
which will be the date (the "Expiration Date") that is 20 business days
following the later of the date of effectiveness of the registration statement
or the date the Exchange Offer is otherwise commenced, unless the Exchange
Offers are extended by the Company in its sole discretion (but in no event to a
date later than           , 1998), in which case the term "Expiration Date"
shall mean the latest date and time to which the Exchange Offers are extended.
Tenders of Old Securities may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date, unless previously accepted for payment
by the Company. The Exchange Offers are not conditioned upon any minimum
principal amount of Old Securities being tendered for exchange. However, the
Exchange Offers are subject to certain conditions which may be waived by the
Company and to the terms and provisions of the Registration Rights Agreements.
Old Securities may be tendered only in denominations of $1,000 and integral
multiples thereof (other than Old Debentures). The Company has agreed to pay the
expenses of the Exchange Offers. See "The Exchange Offers--Fees and Expenses."
The New Securities will bear Interest from the last Interest Payment Date of the
Old Securities to occur prior to the issue date of the New Securities or, if no
such interest has been paid, from March 12, 1998. Holders of the Old Securities
whose Old Securities are accepted for exchange will not receive interest on such
Old Securities for any period subsequent to the last Interest Payment Date to
occur prior to the issue date of the New Securities, if any, and will be deemed
to have waived the right to receive any interest payment on the Old Securities
accrued from and after such Interest Payment Date or, if no such interest has
been paid, from March 12, 1998.
 
    This Prospectus, together with the Letter of Transmittal, is being sent to
all registered holders of Old Securities as of           1998.
 
    Neither the Company nor the Note Issuers will receive any proceeds from the
Exchange Offers. No dealer-manager is being used in connection with the Exchange
Offers. See "Use of Proceeds" and "Plan of Distribution."
 
    Until           ,1998, all broker-dealers effecting transactions in the New
Securities, whether or not participating in the Exchange Offers, may be required
to deliver a Prospectus. This is in addition to the obligations of
broker-dealers to deliver a Prospectus when acting as underwriters and with
respect to their unsold allotments or subscriptions.
 
    No broker-dealer, salesperson or other individual has been authorized to

Exchange Offers other than those contained in this Prospectus and Letter of
Transmittal and, if given or made, such information or representation must not
be relied upon as having been authorized by the Company or the Note Issuers. The

implication that the information herein is correct at any time subject to its
date.

    NSM Cayman and NSM (Del) are corporations organized under the laws of the
Cayman Islands and the State of Delaware, respectively, and the Company is a
public limited company organized under the laws of Thailand. Certain of the
directors and officers of the Note Issuers and the Company and certain of the
experts named in this Prospectus reside outside the United States, and all or a
substantial portion of the assets of such persons and NSM Cayman and the Company
are located outside the United States. As a result, it may not be possible for
investors to effect service of process within the United States upon such
persons, including with respect to matters arising under the Securities Act, or
to enforce against any of them, the Note Issuers or the Company, judgments of
courts of the United States predicated upon the civil liability provisions of
the Federal securities laws of the United States. The Company has been advised
by its Thailand legal counsel, White & Case (Thailand) Limited, that judgments
of United States courts, including judgments predicated upon the civil liability
provisions of the federal securities laws of the United States, are not
enforceable in Thailand, but such judgment or order in the discretion of the
courts of Thailand may be admitted as evidence of an obligation in new
proceedings instituted in the courts of Thailand, which would consider the issue
on the evidence before it.
 
                                      iii

Borough of Manhattan of the City of New York arising out of, related to or
concerning the offering and sale of Securities under this Prospectus.

accounting principles in Thailand ("Thai GAAP"). This Prospectus contains
translations of certain Baht amounts into U.S. Dollars ("U.S.$") at specified

OVERVIEW
 
    NSM is the owner, developer and operator of one of the most advanced and
lowest cost thin-slab/flat-rolled steel mini-mills in the world. NSM's mini-mill
is located in Chonburi, Thailand, and when completed will combine a
technologically advanced mini-mill steel production facility with a contiguous
direct reduced iron facility and finishing facilities. The mini-mill is managed
and operated by NSM Management Company, LLC ("Management Co.") and an
experienced team of international steel executives employed by NSM. Management
Co. receives technical and advisory services from Steel Dynamics, Inc. ("SDI"),
a leading mini-mill operator in the United States, under a long-term management
advisory and technical assistance agreement (the "SDI Agreement"). Concurrently
with the Offerings and in connection with the execution of a license agreement
(the "SDI License Agreement"), which includes the grant by SDI and NSM of
reciprocal license rights to certain technical and operational know-how, SDI
received 74,468,090 ordinary shares, par value 10 Baht per share (The "Ordinary
Shares"). NSM also issued warrants (the "SDI Warrants") to SDI to purchase
11,421,480 Ordinary Shares, which contain exercise provisions that protect SDI
from dilution of its equity interest in the event holders of certain warrants
exercisable for Ordinary Shares issued on the Issue Date in conjunction with the
issuance of the Senior Subordinated Notes (the "Warrants") exercise such
Warrants. In addition to SDI, one or more affiliates of Enron Corp.
(individually and collectively, "Enron"), a U.S.-based company with energy and
project finance expertise throughout the world, and one or more affiliates of
McDonald & Company Securities, Inc. (individually and collectively, "McDonald",
and together with Enron and SDI, the "Management Investors"), acquired (the
"Management Equity Investment") newly issued Ordinary Shares on the Issue Date.
Enron and McDonald, among others, also purchased an aggregate of 45 million
Ordinary Shares in a privately negotiated transaction in the secondary market
for the Company's shares. Enron additionally acquired a significant portion of
the 64,417,180 Ordinary Shares privately placed by the Company concurrently with
the Debenture Offering (the "Private Placement Shares" and, together with the
Management Equity Investment, the "Equity Investments"). Giving effect to the
Transactions and the other purchases described above, the Management Investors
in the aggregate hold a 20.56% interest in the Company's issued and outstanding
Ordinary Shares.
 
    Construction and start-up of the Hot Mill (as defined), the core of the
mini-mill, has been completed. The hot mill rolled its first coil of steel
during operational testing in October 1997 and melted, cast and hot-rolled its
first coil of steel in December 1997. The Company began commercial operations in
the first quarter of 1998. The Company's goal is to be the world's most
efficient and lowest cost producer of high-quality flat-rolled steel products,
including hot-rolled, cold-rolled and galvanized steel, as well as other
specialty steel products. The recent devaluation of the Baht has reduced certain
of the Company's current capital expenditure obligations and may lower certain
of its operating costs.
 
    Upon completion, NSM's mini-mill will consist of three facilities: (i) a
compact strip production ("CSP") thin-slab hot mill (the "Hot Mill") for steel
melting, refining, casting and hot-rolling, (ii) a facility (the "DRI Facility")
for the production of direct reduced iron ("DRI"), which includes a
co-generation electric power plant (the "Co-Gen Facility") in the process of
being developed with Enron, and (iii)
 
                                       1

downstream processing facilities for the production of high-quality pickled and
oiled, cold-rolled, galvanized, and other value-added steel products (the
"Finishing Facilities"). The Hot Mill, DRI Facility and Finishing Facilities are
referred to collectively as the "Mill." The Company believes that the Mill's
design utilizes a unique combination of the best commercially proven
technologies currently in use in some of the most efficient and highest quality
steel manufacturing facilities in the world.
 
    The Hot Mill has a designed annual production capacity of 1.5 million
tonnes. The Hot Mill utilizes advanced technology steel melting and refining,
CSP casting and hot-rolling processes and equipment. The Finishing Facilities,
which are expected to be operational in the first quarter of 1999, will
incorporate a multi-purpose high-capacity production line and several lower
capacity production units with a combined rated annual production capacity of
1.5 million tonnes. The DRI Facility, which is expected to be operational during
the second quarter of 1999, will have an annual rated production capacity of
500,000 tonnes and will provide the Company with a low-cost substitute for
approximately 30% of the scrap in its melt mix. The Company believes that this
equipment will allow it to produce thinner gauge, higher value steel in
hot-rolled form with consistently better tolerances, uniformity and surface
qualities relative to certain other flat-rolled steel producers. NSM believes
that the resulting increased product breadth and cost advantages produced by
combining the DRI Facility, Hot Mill and Finishing Facilities together in a
continuous process will allow it to become a world class flat-rolled steel
producer based on cost, quality and timeliness of delivery.
 
    The world's flat-rolled steel market is dominated by integrated steel
producers using conventional blast furnaces and eight- to ten-inch slab
production methods. The Company believes that thin-slab/flat-rolled steel
mini-mills can compete favorably against integrated steel producers in terms of
cost, quality and timeliness of delivery, while producing superior financial
results. Thailand has historically been one of the largest importers of
flat-rolled steel in the world, ranking third in 1996 in terms of net steel
imported. Virtually all of the steel products imported into Thailand are
produced by high-cost integrated steel producers with lengthy delivery
schedules.
 
    The demand for flat-rolled products in Thailand results, in part, from the
development over the past 20 years of several industries including the
manufacturing of pipe and tube, containers, furniture, appliances and automotive
parts and vehicles. NSM is the only flat-rolled steel producer in Thailand.
Accordingly, the Company believes that it is well positioned to capture a
significant share of the demand for flat-rolled steel in Thailand by producing a
broad range of high-quality products.
 
    In order to ensure consistent and efficient mill utilization and to mitigate
NSM's exposure to the economic difficulties currently being experienced in
Thailand, the Company has entered into eight-year off-take agreements with
Preussag Handel GmbH ("Preussag") and Klockner Steel Trading ("Klockner")
(collectively, the "Off-Take Agreements"). Preussag and Klockner are two
international steel trading and processing companies which sell high-quality,
high-grade steel products throughout the world. Under the Off-Take Agreements,
Preussag and Klockner will be obligated to purchase, in aggregate, 100% of the
Company's production in 1998 through 2002, and 25% of the Company's production
in the years 2001 through 2005. NSM may, at is option, reduce the percentage of
its production sold under the Off-Take Agreements to as little as 67% in 1998,
50% in 1999 and 25% in 2000, if the Company believes it could maximize sales
revenues through sales to other customers. Under the Indentures, sales by NSM to
customers other than Preussag and Klockner, to the extent that the aggregate of
such sales results in receivables outstanding in excess of U.S.$10 million, must
be supported by letters of credit if the customer does not have an investment
grade credit rating. All sales to Preussag and Klockner and substantially all
other export sales will be U.S.$ denominated.
 
    In addition to the Off-Take Agreements, the Company has entered into a
commercial assistance agreement with the former chief commercial officer of U.S.
Steel to facilitate the Company's introduction to flat-rolled steel customers.
Based on international customer inquiries received by the Company to date, the
Company believes that it could increase the percentage of its annual production
sold under off-take
 
                                       2

agreements in 2001 through 2005 should economic conditions in the Asia-Pacific
region warrant. The Company also believes, that as a low-cost producer of
high-quality steel products, it will have the option to sell its products in
either domestic or world markets, including the United States.
 
    NSM has entered into various arrangements to ensure its access to and
availability of electric power, natural gas, oxygen, coal and iron ore. NSM has
entered into arrangements under which the Provincial Electricity Authority of
Thailand ("PEA") and the Petroleum Authority of Thailand ("PTT") will provide
NSM with electric power and natural gas. PEA and PTT are government entities
charged with providing electricity and natural gas, respectively, to Thailand's
industrial base. NSM will benefit from two new power substations adjacent to the
Mill constructed by Electric Generating Authority of Thailand ("EGAT") and from
two sets of new power lines which run to the Mill site, all recently constructed
by PEA. NSM also has access to a long-term supply of oxygen and other industrial
gases from Bangkok Industrial Gas, which has recently constructed an oxygen
plant adjacent to the Mill. Coal and iron ore, two important raw materials
needed to produce DRI, are being supplied under long-term contracts by SSM Coal
BV ("SSM"), the owner of a Vietnamese coal mine, and MMTC Limited ("MMTC"), an
iron ore trading company based in India.
 
    When complete, the Company estimates that its total investment in the Mill
for property, plant, land, buildings, machinery and equipment will be
approximately U.S.$764 million. The Company's investment in the land, buildings,
machinery and equipment of the Mill as of December 31, 1997 was approximately
U.S.$588 million, including approximately U.S.$514 million in connection with
the construction of the Hot Mill, approximately U.S.$32 million in connection
with the DRI Facility and approximately U.S.$42 million in connection with the
Finishing Facilities.
 
    During 1998, while the DRI Facility and Finishing Facilities are expected to
be under construction, interest on the Notes will be paid from amounts on
deposit in the Notes DSR Account. As of December 31, 1997, after giving pro
forma effect to the Transactions, the Company would have had total shareholders'
equity of U.S.$158 million and total indebtedness of U.S.$771 million, of which
U.S.$336 million would have been secured equally and ratably with the
Guaranties. See "Risk Factors--Risk Related to Forward Looking Information."
 
PROJECT ADVANTAGES
 
    NSM believes that it enjoys a number of advantages over other flat-rolled
steel producers and that these advantages will facilitate the implementation of
its business strategy. Through the use of advanced technology throughout the
Mill, the Company believes that its projected cost structure will place it among
the lowest cost producers of flat-rolled steel products in the world.
Complementing the Company's projected low cost structure is its designed
capability to produce a full range of flat-rolled products, including high
value-added products that previously could only be produced by higher cost
integrated steel producers. The Company believes that this ability to produce
high value-added products coupled with its projected low cost structure, will
enable it to compete effectively in selling its products, to the domestic and
world steel markets. Further complementing the Company's projected cost
structure and product capabilities will be its right to obtain certain technical
and operational advice and consultation services from SDI, as well as access to
the strategic expertise of Enron and McDonald.
 
BUSINESS STRATEGY
 
    NSM's business strategy is to use its advanced Hot Mill, DRI Facility and
Finishing Facilities technologies to produce superior quality flat-rolled steel
in a variety of high value-added forms. The principal elements of the Company's
strategy include:
 
    - ACHIEVE CONVERSION COSTS AMONG THE LOWEST IN THE STEEL INDUSTRY. The
      Company believes that the design of the Mill represents substantial
      efficiency improvements over earlier mini-mills using CSP technology.
      These improvements are expected to substantially reduce the cost and
      production time
 
                                       3

      of the steel-making process, limit electric arc furnace ("EAF") power-off
      and downtime, reduce consumption of consumable inputs and ultimately
      produce higher quality steel. By designing and utilizing equipment that is
      efficient, consumes fewer raw materials and improves the consistency and
      reliability of the steel making process, the Company believes that its per
      tonne manufacturing costs will be among the lowest in the steel industry.
 
    - EMPHASIZE VALUE-ADDED PRODUCTS. NSM believes that it will be able to
      produce thinner gauge steel in hot-rolled form with consistently better
      uniformity, tolerances and surface quality relative to certain other
      flat-rolled steel producers. The Company also believes that its
      high-quality, thinner gauge hot-rolled products will compete favorably
      with certain more expensive cold-rolled (further processed) products,
      enabling it to achieve higher margins. The Company believes that thinner
      gauge, hot-rolled products, and other value-added products, may be less
      susceptible to the price fluctuations commonly found in the spot market
      for commodity grade steel. The design of the Finishing Facilities' process
      lines is expected to result in higher quality products, significant cost
      savings and yield improvements relative to the processing systems used by
      certain other flat-rolled steel producers. In addition, the Company
      expects to devote a substantial portion of its hot-rolled capacity to the
      production of higher margin pickled and oiled, cold-rolled, galvanized,
      and other value added steel products. The Company believes that the
      resulting increased product breadth and cost advantages will allow it to
      compete favorably on a cost and quality basis with any steel producer in
      the world.
 
    - SECURE A SOLID BASELOAD OF U.S.$ SALES. In order to ensure consistent and
      efficient Mill utilization and to balance U.S.$ revenues with U.S.$ debt
      service and expense requirements, the Company has entered into the
      Off-Take Agreements. Under the Off-Take Agreements, Preussag and Klockner
      will be obligated to purchase, in aggregate, 100% of the Company's
      production in 1998 through 2002, and 25% of the Company's production in
      the years 2001 through 2005. NSM may, at is option, reduce the percentage
      of its production sold under the Off-Take Agreements to as little as 67%
      in 1998, 50% in 1999 and 25% in 2000, if the Company believes it could
      maximize sales revenues through sales to other customers. Under the
      Indentures, sales by NSM to customers other than Preussag and Klockner, to
      the extent that the aggregate of such sales results in receivables
      outstanding in excess of U.S.$10 million, must be supported by letters of
      credit if the customer does not have an investment grade credit rating.
      All sales to Preussag and Klockner and substantially all other export
      sales will be U.S.$ denominated. Based on international customer
      inquiries, the Company believes that it could substantially increase the
      percentage of its annual production sold under off-take agreements in 2001
      through 2005 should economic conditions in the Asia-Pacific region
      warrant. The Company believes that as a low-cost producer of high-quality
      steel products, it will have the option to sell all of its products in
      either domestic or world markets, including the United States.
 
    - MAXIMIZE MINI-MILL ADVANTAGES. The Company has adopted a combination of
      technologies and management techniques which management believes will
      provide it with the flexibility to deliver custom ordered, just-in-time,
      high-quality products to customers with minimal lead times. NSM has
      adopted management and personnel policies designed to take advantage of
      the opportunities inherent in the technological revolution in the
      flat-rolled steel industry. The Company expects its energy consumption,
      man-hours per tonne produced and the environmental impact of the
      operations to be among the lowest in the industry. The Company intends to
      use its advanced technologies to develop profitable niche market products.
 
    - UTILIZE LEADING MINI-MILL OPERATIONAL AND MANAGEMENT TECHNIQUES. The
      Company has entered into agreements with a number of leading steel
      mini-mill developers and operators in order to make available to
      Management Co. or the Company certain technical know how and business
      practices. Under the terms of the SDI Agreement, SDI, a company whose
      executives and managers pioneered the development of thin-slab/flat-rolled
      technology and directed the construction and operation of
 
                                       4

      the world's first thin-slab/flat-rolled minimill, will provide management
      advisory and periodic on-site technical support to Management Co. Hylsa
      S.A. ("Hylsa"), under a technical assistance and training agreement (the
      "Hylsa Agreement"), has provided training to over 140 NSM employees at its
      Monterey, Mexico plant, and will continue to provide training and on-site
      technical support. Hylsa is recognized in the world steel making community
      for producing high-quality, thin-gauge products utilizing CSP technology.
      From early 1996 through mid-1997, the Company received certain technical
      assistance and employee training for over 170 NSM employees from Nucor
      Corporation ("Nucor"), currently an operator of eight mini-mills in the
      United States.
 
    - SECURE RAW MATERIAL SOURCES. The primary raw materials and utilities used
      to produce DRI and flat-rolled steel products are coal, iron ore,
      electricity and scrap. To secure access to adequate low-cost supplies of
      these inputs, NSM has entered into long-term arrangements for the supply
      of coal, iron ore and electricity with SSM Coal BV, MMTC Limited, and PEA,
      respectively. For scrap, NSM will have access to both the domestic and
      global scrap markets. Management believes that due to the recent Baht
      devaluation and the logistical and regulatory obstacles to exporting scrap
      from Thailand, NSM's near term domestic scrap costs will be U.S.$20-30 per
      tonne lower than world market prices.
 
    - EXPLOIT STRATEGIC LOCATION. The Company is the only flat-rolled steel
      producer in Thailand, historically one of the world's largest importers of
      finished and semi-finished flat-rolled steel. In 1996, Thailand ranked
      third in the world in terms of imported steel. The Company believes that
      demand in Thailand for steel products will return to historical levels
      following improvements in domestic economic conditions. The Company
      believes that strong domestic demand combined with import tariffs on
      certain steel products would allow the Company to achieve higher profit
      margins on the sale of its products in Thailand relative to sales outside
      of Thailand.
 
    - UTILIZE THE EXPERTISE OF SDI, ENRON AND MCDONALD. NSM and Management Co.
      have contracted to acquire certain strategic and financial expertise that
      will enhance NSM's ability to compete both financially and operationally
      in the world steel market. By becoming equity owners of NSM and through
      their representation on the Company's board of directors, the Company
      expects that SDI's, Enron's and McDonald's representatives on the board of
      directors will provide the Company with certain know how, expertise and
      knowledge.
 
    - PURSUE EXPANSION OPPORTUNITIES. In order to lower production costs through
      economies of scale, the Company intends to pursue expansion of the Mill if
      market conditions warrant such an expansion. To facilitate expansion of
      DRI production capacity, NSM designed the DRI Facility to accommodate a
      tripling of capacity. In addition to mitigating NSM's reliance on the
      global scrap market, an expanded DRI Facility would produce a significant
      amount of additional electric power at economically attractive rates for
      use in the Hot Mill. NSM also designed the Hot Mill and Finishing
      Facilities to facilitate expansion. In aggregate, the cost of increasing
      the capacity of the DRI Facility by 1.0 million tonnes per year, the Hot
      Mill by 1.2 million tonnes per year and the Finishing Facilities by
      100,000 tonnes per year is estimated by the Company to approximate
      U.S.$250 million.

    United States Federal
      Income Tax
      Consequences..........  The exchange of Old Securities for New Securities pursuant to
                              the Exchange Offers will not result in any income, gain or
                              loss to holders who participate in the Exchange Offers or to
                              the Note Issuers for U.S. federal income tax purposes. See
                              "Tax Considerations."
 
    Resale..................  The Note Issuers are making the Exchange Offers in reliance on
                              the position of the staff of the Commission as set forth in
                              certain no-action letters addressed to other parties in other
                              transactions. However, the Note Issuers have not sought their
                              own no-action letter and there can be no assurance that the
                              staff of the Commission would make a similar determination
                              with respect to the Exchange Offers as in such other
                              circumstances. Based on these interpretations by the staff of
                              the Commission, the Note Issuers believes that New Securities
                              issued pursuant to the Exchange Offers in exchange for Old
                              Securities may be offered for resale, resold and otherwise
                              transferred by a holder thereof other than (i) a broker-dealer
                              who purchased such Old Securities directly from the Note
                              Issuers to resell pursuant to Rule 144A or any other available
                              exemption under the Securities Act or (ii) a person that is an
                              "affiliate" (as defined in Rule 405 of the Securities Act) of
                              the Note Issuers without compliance with the registration and
                              prospectus delivery provisions of the Securities Act; PROVIDED
                              that such New Securities are acquired in the ordinary course
                              of such holder's business and that such holder is not
                              participating, and has no arrangement or understanding with
                              any persons to participate, in the distribution of such New
                              Securities. Holders of Old Securities accepting the Exchange
                              Offers will represent to the Note Issuers in the Letter of
                              Transmittal that such conditions have been met. Any holder who
                              participates in the Exchange Offers for the purpose of
                              participating in a distribution of the New Securities may not
                              rely on the position to the staff of the Commission as set
                              forth in these no-action letters and would have to comply with
                              the registration and prospectus delivery requirements of the
                              Securities Act in connection with any secondary resale
                              transaction. A secondary resale transaction in the United
                              States by a holder who is using the Exchange Offers to
                              participate in the distribution of New Securities must be
                              covered by a registration statement containing the selling
                              securityholder information required by Item 507 of Regulation
                              S-K of the Securities Act. Each broker-dealer (other than an
                              "affiliate"

                              of the Company) that receives New Securities for its own
                              account pursuant to the Exchange Offers must acknowledge that
                              it acquired the Old Securities as the result of market-making
                              activities or other trading activities and will deliver a
                              prospectus in connection with any resale of such New
                              Securities. 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 New Securities
                              received in exchange for Old Securities where such Old
                              Securities were acquired by such broker-dealer as a result of
                              market-making activities or other trading activities. In
                              addition, pursuant to section 4(3) under the Securities Act,
                              until            ,     , all dealers effecting transactions in
                              the New Securities, whether or not participating in the
                              Exchange Offers, may be required to deliver a Prospectus. The
                              Note Issuers have agreed that, for a period of 180 days after
                              the date of this Prospectus, it will make this Prospectus
                              available to any broker-dealer for use in connection with any
                              such resale. See "Plan of Distribution." Any broker-dealer who
                              is an affiliate of the Note Issuers may not rely on such
                              no-action letters and must comply with the registration and
                              prospectus delivery requirements of the Securities Act in
                              connection with any secondary resale transaction. See "The
                              Exchange Offers--Purpose of the Exchange Offers."
 
    Remaining Old
      Securities............  Holders of Old Securities who do not tender such Old
                              Securities in the Exchange Offers or whose Old Securities are
                              not accepted for exchange will continue to hold such Old
                              Securities and will be entitled to all the rights and
                              preferences, and will be subject to the limitations,
                              applicable thereto under the Indenture. All untendered and
                              tendered but unaccepted Old Securities (collectively, the
                              "Remaining Old Securities") will continue to bear legends
                              restricting their transfer. In general, the Old Securities may
                              not be offered or sold unless registered under the Securities
                              Act, except pursuant to an exemption from, or in a transaction
                              not subject to, the Securities Act and applicable state
                              securities laws. To the extent that the Exchange Offers are
                              effected, the trading market, if any, for the Remaining Old
                              Securities could be adversely affected. See "Risk
                              Factors--Consequences of Failure to Properly Tender Old Notes
                              Pursuant to the Exchange Offers." See "The Exchange
                              Offers--Terms of the Exchanges."
 
    Exchange Agent..........  The exchange agent with respect to the Exchange Offers is
                                                  (the "Exchange Agent"). The address and
                              telephone number of the Exchange Agent are set forth in "The
                              Exchange Offers--Exchange Agent."
 
    Use of Proceeds.........  There will be no proceeds to the Note Issuers from the
                              exchange pursuant to the Exchange Offers. See "Use of
                              Proceeds."
 
    Relationship to the Old
      Notes.................  The form and terms of the New Securities are substantially the
                              same as the form and terms of the Old Securities except that
                              the New Securities are registered under the Securities Act
                              and, therefore, will not bear

 
                                       8

 

                           
                              legends restricting the transfer thereof and will not contain
                              the registration rights and liquidated damages provisions
                              relating to the Old Securities. See "Description of Notes" and

                              other than as a result of enforcement of the security
                              interests granted in the Collateral, in the event that there

    The following summary financial information as at December 31, 1994, 1995,
1996, 1997 and for the years ended December 31, 1995, 1996, 1997 have been
derived from, and are qualified in their entirety by reference to, the Company's
Audited Financial Statements and Notes thereto appearing elsewhere in this
Prospectus. Such statements have been audited by Peat Marwick Suthee Limited,
independent public accountants, as of and for each of the years in such period.
The Company's Audited Financial Statements are prepared in conformity with
generally accepted accounting principles in Thailand ("Thai GAAP"), which differ
from generally accepted accounting principles in the United States ("U.S.
GAAP"). The following data should be read in conjunction with the Company's
Audited Financial Statements and the Notes thereto, and Management's Discussion
and Analysis of Financial Condition, which are included elsewhere in this
Prospectus. The unaudited pro forma balance sheet information presents the
financial position of the Company as at December 31, 1997 after giving effect to
the Offerings, the Debenture Offering and the Equity Investments and the
application of the proceeds therefrom as if they occurred on that date. The pro
forma adjustments are based on certain assumptions that the Company believes are
reasonable. The unaudited pro forma balance sheet data should be read in
conjunction with "Capitalization," "Management's Discussion and Analysis of
Financial Condition" and the Company's Audited Financial Statements and the

                                  RISK FACTORS
 
    AN INVESTMENT IN THE SECURITIES BEING OFFERED BY THIS PROSPECTUS INVOLVES A
HIGH DEGREE OF RISK. IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS
PROSPECTUS, THE FOLLOWING FACTORS, CERTAIN OF WHICH ARE NOT TYPICALLY ASSOCIATED
WITH INVESTING IN SECURITIES OF COMPANIES LOCATED IN THE UNITED STATES, SHOULD
BE CAREFULLY CONSIDERED BY PROSPECTIVE INVESTORS IN EVALUATING AN INVESTMENT IN
THE SECURITIES OFFERED HEREBY.
 
CONSEQUENCES OF FAILURE TO PROPERLY TENDER OLD SECURITIES PURSUANT TO THE
  EXCHANGE OFFER
 
    Holders of Old Securities who do not exchange their Old Securities for New
Securities pursuant to the Exchange Offers will continue to be subject to the
following restrictions on transfer with respect to their Old Securities: (i) the
remaining Old Securities may be resold only if registered pursuant to the
Securities Act, if any exemption from registration is available thereunder, or
if neither such registration nor such exemption is required by law, and (ii) the
remaining Old Securities will bear a legend restricting transfer in the absence
of registration or an exemption therefrom. Issuers do not currently anticipate
that they will register the Old Securities under the Securities Act. To the
extent that Old Securities are tendered and accepted in connection with the
Exchange Offers, any trading market for remaining Old Securities could be
adversely affected.
 
    Issuance of the New Securities in exchange for the Old Securities pursuant
to the Exchange Offers will be made only after timely receipt by the Exchange
Agent of such Old Securities, a properly completed and duly executed Letter of
Transmittal and all other required documents. Therefore, holders of the Old
Securities desiring to tender such Old Securities in exchange for New Securities
should allow sufficient time to ensure timely delivery. The Company and the Note
Issuers are under no duty to give notification of defects or irregularities with
respect to tenders of Old Securities for exchange. Old Securities that are not
tendered or that are tendered but not accepted by the Company and the Note
Issuers for exchange will, following consummation of the Exchange Offer,
continue to be subject to the existing restrictions upon transfer thereof under
the Securities Act and, upon consummation of the Exchange Offers, certain
registration rights under the Registration Rights Agreements will terminate.
 
OPERATING AND START-UP RISKS
 
    The Company's only assets are the share capital of NSM (Del) and NSM Cayman
and its interest in the Mill, which has no operating history and, with regard to
the DRI Facility and Finishing Facilities, is still under construction.
Management Co. has a very limited history of operations. The Company will be
subject to all of the risks inherent in the establishment of a new steel mill.
The Mill's commercial viability and profitability are dependent upon, among
other things, its completion and successful operation. No assurance can be given
that the Company and Management Co. will be able to complete the Mill, to
sustain successful operations or that its operations will achieve commercial
viability.
 
    Although the Company believes that any start-up difficulties it experiences
will be typical of those encountered when a new steel mill commences production,
there is no assurance that the Company will not continue to experience
operational difficulties beyond those encountered during the start-up process,
or that it will ultimately achieve or be able to sustain full production. Also,
to the extent the quality of the steel produced by the Mill does not comply with
the requirements of the Off-Take Agreements, the purchasers' obligations to
purchase the Company's steel production under the Off-Take Agreements may be
adversely affected. In addition, the Company could experience construction,
start-up or operational difficulties as it implements the DRI Facility and the
Finishing Facilities. There can be no assurance that the Company and Management
Co. will be able to operate the Mill at full capacity or that the DRI Facility
and the Finishing Facilities will be successfully built, started-up and
integrated with the Company's Hot Mill.
 
    The Company's operation of the Hot Mill and the construction and start-up of
the DRI Facility and the Finishing Facilities may place a strain on the
Company's administrative, operational and financial
 
                                       19

resources. The failure to produce at full capacity, coordinate its sales and
marketing efforts with production or manage its future development and growth,
or the emergence of unexpected production difficulties, could adversely affect
the Company's business, results of operations, financial condition or prospects
and its ability to pay its obligations on the Securities.
 
    In addition, the operation of the Mill may be adversely affected by many
factors, such as production disruptions, industrial accidents, environmental
hazards, technical difficulties or equipment failures, labor disputes, late
delivery of supplies, and periodic or extended interruptions due to inclement or
hazardous weather conditions, fires, explosions or other accidents or acts of
force majeure. Such risks could result in damage to, or destruction of, the
Mill, personal injury, environmental damage, delays in production, losses and
legal liability. Any prolonged downtime or shutdowns of the Hot Mill, DRI
Facility and Finishing Facilities could materially adversely affect the
Company's business, results of operations, financial condition or prospects and
its ability to pay its obligations under the Securities.
 
SUBSTANTIAL INDEBTEDNESS; ADVERSE CONSEQUENCES OF FINANCIAL LEVERAGE
 
    Following the Offerings, the Note Issuers and the Company have significant
Indebtedness and debt service obligations. As of December 31, 1997, on a pro
forma basis after giving effect to the Offerings, the Equity Investments and the
application of the net proceeds therefrom as described under "Use of Proceeds,"
the Note Issuers and the Company would have had approximately U.S.$771 million
aggregate principal amount of Indebtedness outstanding (including the
Guaranties), representing approximately 83% of the Company's total consolidated
capitalization excluding working capital. See "Capitalization." There can be no
assurance that the Note Issuers and the Company will have sufficient resources
to pay the interest expense or principal associated with such indebtedness. See
"Description of Certain Indebtedness."
 
    The degree to which the Note Issuers and the Company are leveraged could
have important consequences to holders of the Securities, including: (i) the
Company's ability to obtain additional financing for working capital, capital
expenditures, acquisitions or general corporate purposes will be limited; (ii) a
substantial portion of the Company's expected cash flow from operations will be
required to be dedicated to the payment of interest on the Notes and other
existing indebtedness, thereby reducing the funds available to the Company for
other purposes, including operation of the Mill and future business
opportunities; (iii) the Company is substantially more leveraged than certain of
its competitors, which might place the Company at a competitive disadvantage;
(iv) the Company may be hindered in its ability to adjust rapidly to changing
market conditions; and (v) the Company's substantial degree of leverage could
make it more vulnerable in the event of a downturn in general economic
conditions or in its business.
 
    The Company's ability to meet its debt service obligations and to reduce its
total indebtedness will depend upon the Company's future performance, which will
be subject to general economic conditions and to financial, business, and other
factors affecting the operations of the Mill, many of which are beyond the
control of the Company. There can be no assurance that the Company's business
will be able to generate cash flow at levels sufficient to satisfy its debt
service requirements. If in the future the Company is unable to generate
sufficient cash from the operations of the Mill to allow the Note Issuers to
make scheduled interest payments on the Securities and indebtedness under the
Bank Credit Facility, to make principal payments on indebtedness under the Bank
Credit Facility, to pay the Securities at maturity, or to meet their other
obligations and commitments, the Company will be required to adopt one or more
alternatives, such as refinancing or restructuring the indebtedness of the
Company on the Note Issuers, reducing or delaying planned expansion, selling
assets or seeking to raise additional debt or equity capital. There can be no
assurance that any of these alternatives could be effected on a timely basis, on
satisfactory terms or at all. In addition, the terms of existing or future debt
agreements, including the Indentures, may prohibit the Company from adopting
some of these alternatives.
 
    The Indentures contain financial and operating covenants that will limit the
discretion of the Note Issuers and the Company with respect to certain business
matters. These covenants will place significant
 
                                       20

restrictions on, among other things, the ability of the Note Issuers and the
Company to incur additional Indebtedness, to create liens or other encumbrances,
to make certain payments and investments, and to sell or otherwise dispose of
assets and merge or consolidate with other entities. See "Description of Notes
and Guaranties--Certain Covenants." A failure to comply with the obligations
contained in the Indentures could result in an event of default under the
Indentures which could permit acceleration of the related debt and acceleration
of debt under other instruments that contain cross-acceleration or cross-default
provisions. Other outstanding Indebtedness is or will be subject to covenants
that are substantially different than those set forth in the Indentures. In
particular, the covenants and events of default in the Bank Credit Facility and
the up to U.S.$150 million working capital facility provided by BNP (the
"Working Capital Facility") are or will be quite restrictive and generally will
give the bank lenders broad latitude in controlling the management of the
Company in the event of a breach of such agreements. See "Description of Certain
Indebtedness." A failure to comply with the obligations contained in the
documents evidencing the Company's other outstanding Indebtedness could result
in an event of default under such Indebtedness which could permit an
acceleration of the repayment of the Indebtedness under the Securities. A
default on such indebtedness could occur and enforcement of such creditors'
security interests could result even though there had not been any default under
the Indentures. In addition, pursuant to the terms of the Bank Credit Facility,
the Company has agreed that other than as a result of enforcement of the
security interests granted in the Collateral, in the event that there are
insufficient funds available at any time to make all payments of principal or
interest then due under the Bank Credit Facility and the Securities, it will pay
100% of any interest and 50% of any principal then due under the Bank Credit
Facility prior to paying any interest then due on the Securities. See
"Description of Certain Indebtedness," "Description of Notes and Guaranties" and
"Security Arrangements."
 
POLITICAL AND ECONOMIC FACTORS
 
    The Company's results of operations and financial condition may be
influenced by the political situation in Thailand and by the general state of
the Thai economy. The political situation in Thailand has been unstable from
time to time in recent years and future political and economic instability in
Thailand could have an adverse effect on the Company's business and results of
operations. Any potential investor in the Securities should pay particular
attention to the fact that the Company is governed in Thailand by a political,
economic, legal and regulatory environment that may differ significantly from
that which prevails in other countries.
 
    Thailand is a constitutional monarchy. Under the constitution, the King is
Head of State, Commander of the Armed Forces and Patron of all Religions.
Executive power is vested in the cabinet while legislative power is exercised by
the elected bicameral National Assembly. Thailand has experienced several
changes of government and changes in its political system since World War II. A
new constitution became effective on October 11, 1997. There can be no assurance
that Thailand's current government or political system will continue unchanged
throughout the term of the Securities. Additionally, there can be no assurance
that any future change in the government will be the result of democratic
processes.
 
    Although Thailand's economy has been characterized in the past decade by
high growth rates, in 1996 and particularly in 1997, economic growth slowed
significantly in relation to historical levels. In late 1996 and throughout
1997, Thailand experienced significant economic weakness, resulting primarily
from declines in the property and finance industries, a sharp reduction in
financial liquidity and a general deterioration in investor confidence.
Inflation in Thailand has increased and interest rates have remained among the
highest in the region. In addition, the country has had recurring trade balance
and current account deficits. The government of Thailand also agreed on August
5, 1997, to accept the austerity measures of the International Monetary Fund
("IMF") aimed at rehabilitating and restructuring the economy as a condition to
receipt of IMF-led loans and financial assistance of approximately U.S.$17.2
billion. See "Annex A--The Kingdom of Thailand--IMF-led Financial Assistance"
and "Fiscal Update and Financial Sector Measures." International credit rating
agencies, including Moody's Investors Service, Inc. ("Moody's") and Standard &
Poor's Corporation ("S&P"), have recently downgraded Thai
 
                                       21

sovereign as well as various Thai corporate and financial institutions' debt
ratings. Between January 3, 1996 and December 31, 1997, the Stock Exchange of
Thailand Index ("SET") fell from 1,323.43 to 372.69. On December 8, 1997, the
government terminated the operations of 56 of the 91 finance companies in
Thailand. The Company expects that the number of bankruptcies in Thailand and
Southeast Asia generally, including among its potential customers, will
increase.
 
    There can be no assurance that: the deteriorating economy in Thailand and in
Southeast Asia generally; the rise in interest rates and inflation in Thailand
and other Southeast Asian countries; the general decline of share prices on the
SET and other regional stock exchanges; the lack of liquidity and stability in
the Thai and other Southeast Asian finance industries; and other factors
including measures taken by the government of Thailand in response to
deteriorating economic conditions, will not adversely affect the Company's
ability to finance its working capital needs, collect on its receivables for
goods shipped, build market share internationally and in Thailand, or otherwise
adversely affect its financial condition, results of operations or cash flows.
Further, there can be no assurance that the deterioration in the economies of
Thailand and Southeast Asia will not continue or materially worsen. In light of
the deteriorating economies of Thailand and Southeast Asia generally, the
Company's ability to sell projected production levels will depend in significant
part on its ability to access export markets worldwide.
 
THAI EXCHANGE CONTROL RESTRICTIONS; CONSTRAINTS IMPOSED BY MONETARY CONTROLS
 
    On January 6, 1998, the Thai Cabinet approved the issuance of a Ministry of
Finance regulation to limit the U.S.$ holding period for exporters in an effort
to curtail currency speculation and increase the U.S.$ supply in the local
economy. Previously, exporters were required to be paid within 180 days and to
sell or deposit the proceeds in a foreign currency account with an authorized
bank in Thailand within 15 days of receiving such proceeds. However, according
to the January 1998 Regulation, exporters must now be paid within 120 days,
after which they have seven days in which to sell or deposit the proceeds in a
foreign currency account in Thailand. This requirement applies to all export
proceeds earned by a Thai company outside Thailand.
 
    A Thai entity may open a foreign currency account under the following
conditions: (i) the account must be with an authorized bank in Thailand and the
funds must originate from abroad; (ii) remittance abroad of funds deposited in
such an account for payment of ordinary business transactions would require
submission of supporting evidence and approval of the Bank of Thailand; and
(iii) the total amount of daily outstanding balances in such an account must not
exceed U.S.$5 million, otherwise, such excess amount would be required to be
converted to Baht.
 
    An exemption to these regulations allows a depositor to keep deposits in
U.S.$ up to an amount not to exceed the depositor's obligations to foreign
creditors and the international banking facilities of Thailand commercial banks
payable within the next three months. Funds deposited in a foreign currency
account may be withdrawn for, inter alia, payment of interest and principal due
on offshore debt repayments. Proof that the payment of interest is required must
be submitted with the bank in which the currency is deposited each and every
time an application to withdraw and repatriate foreign currency is made. As a
general matter, the outward remittance from Thailand of dividends, interest or
capital gains from the transfer of securities after payment of any applicable
Thai taxes, if any, may be made if the amount does not exceed U.S.$5,000 per
remittance, beyond which amount, a report must be made to the Bank of Thailand.
 
    Parties may apply for an exemption or relaxation from the "strict
observance" of the above requirements. The Company was able to obtain waivers
from the Bank of Thailand which would allow the Company to keep certain U.S.$
amounts of export earnings offshore in certain account for an amount not to
exceed U.S.$130 million each year through the redemption of the Securities.
Additionally, the Company was also granted an approval from the Bank of Thailand
which would allow the Company to keep U.S.$ amounts in excess of U.S.$5 million
in accounts in Thailand for an amount not to exceed the Company's obligations in
foreign currencies payable within three months from the date of deposit.
 
                                       22

    Any excess amount of foreign currencies must be converted into Baht. Such
conversion would require the Company to bear exchange rate risks as many of the
Company's obligations, including payments on the Notes, are U.S.$ denominated.
If the Company is unable to maintain these waivers and is required to convert
such revenue into Baht, any devaluation of the Baht against the U.S.$ could have
an adverse effect on the Company's financial condition as results of operations
and could materially impair the Company's ability to repay its U.S.$
obligations, including payments on the Securities. There can be no assurance
that proceeds of exports will be available in sufficient amounts to satisfy
payment obligations on the Securities.
 
EXCHANGE RATE FLUCTUATIONS
 
    Prior to July 1997, the Bank of Thailand determined the value of the Baht
based on a "basket," the composition of which was not made public but of which
the U.S.$ was the principal component. Prior to July 1997, the Baht had a
history of stability, trading in a narrow range of 24.47 Baht to 25.97 Baht to
the U.S.$1.00, as a result of frequent intervention by the Bank of Thailand
through purchases and sales of U.S.$. However, on July 2, 1997, under
substantial market pressure, the Government floated the Baht and effectively
ceased such intervention, and the value of the Baht, as reflected in the Noon
Buying Rate, declined from 24.520 Baht per U.S.$1.00 on July 1, 1997 to 56.10
Baht per U.S.$1.00 on January 12, 1998 and stood at 39.15 Baht to U.S.$1.00 on
May 15, 1998. There can be no assurance that the value of the Baht will not
decline further, increase or continue to fluctuate widely against other
currencies in the future. Adverse economic conditions in Thailand and the region
incidental to the devaluation of the Baht may also reduce overall demand for the
Company's products and the Company's customers' ability to pay for them, and
there can be no assurance that such reduced demand will not have an adverse
effect on the Company.
 
    The Company's functional currency is the Baht, however, the Company will
have significant U.S.$ denominated assets and liabilities. Therefore,
fluctuations of the value of the Baht relative to the U.S.$ may cause the
Company to recognize material foreign exchange gains or losses which could
adversely affect the Company's results of operations and financial condition.
The Company from time to time may hedge its currency positions to attempt to
avert any adverse consequences of exchange rate fluctuations; however, there can
be no assurance that the Company will be able to successfully hedge its exchange
rate exposure or that it will be able to hedge such exposure at a satisfactory
cost. See "Annex A--The Kingdom of Thailand."
 
RANKING OF THE SENIOR SUBORDINATED NOTES AND THE SENIOR SUBORDINATED GUARANTY;
  LIMITATIONS ON ENFORCEMENT OF COLLATERAL
 
    The indebtedness evidenced by the Senior Subordinated Notes and the Senior
Subordinated Guaranty will be senior secured obligations of the Note Issuers and
the Company, as the case may be, but the payment of principal of, premium,
interest and Additional Accounts, if any, on the Senior Subordinated Notes and
the Senior Subordinated Guaranty will be subordinate in right of payment to the
prior payment in full of all Specified Senior Indebtedness of the Note Issuers
and the Company, as the case may be. The Senior Subordinated Notes and Senior
Subordinated Guaranty will rank PARI PASSU with all other Senior Indebtedness of
the Note Issuers and the Company, as the case may be, and senior in right of
payment to all existing and future Indebtedness of the Notes Issuers and the
Company that is designated as subordinate or junior in right of payment to the
Notes and Guaranties, including the Debentures. The Senior Notes and certain
refinancings thereof will constitute all the Specified Senior Indebtedness of
the Note Issuers. The Senior Guaranty and guarantees of certain indebtedness
refinancing the Senior Notes will constitute all the Specified Senior
Indebtedness of the Company. The Debentures and the Debenture Guaranty will be
subordinate to all Debenture Specified Senior Indebtedness.
 
    At all times that (a) a Default has occurred and is continuing under the
Senior Note Indenture and (b) the aggregate principal amount owed to the holders
of Senior Notes at such time exceeds U.S.$50 million, the holders of the Senior
Subordinated Notes shall (A) refrain from taking any action toward collection or
enforcement of the Pledged NSM Stock or Collateral, including action toward
foreclosure upon the
 
                                       23

Pledged NSM Stock or Collateral, absent the consent of the holders of a majority
of the aggregate principal amount of Senior Notes outstanding and (B) be deemed
to have voted with respect to the Pledged NSM Stock or Collateral, including
without limitation in any foreclosure, bankruptcy, insolvency or similar
proceeding, in the same manner and to the same effect as the holders of a
majority of the aggregate principal amount of Senior Notes. See "Security
Arrangements--Enforcement of Collateral."
 
    In the event of the bankruptcy, liquidation or reorganization of the Note
Issuers or Company, as the case may be, the assets of the Note Issuers or
Company, respectively, will be available to pay the Senior Subordinated Notes
and the Debentures only after all Specified Senior Indebtedness or Debenture
Specified Senior Indebtedness as the case may be, has been paid in full.
Sufficient funds may not exist to pay amounts due on the Senior Subordinated
Notes and the Debentures in such event. In addition, the subordination
provisions of the Senior Subordinated Note Indenture and the Debenture Indenture
provide that no payment may be made with respect to the Senior Subordinated
Notes and the Debentures during the continuance of a payment default under any
Specified Senior Indebtedness or Debenture Specified Senior Indebtedness, as the
case may be. Furthermore, if certain non-payment defaults exist with respect to
Specified Senior Indebtedness or Debenture Specified Senior Indebtedness, as the
case may be, the holders of such Specified Senior Indebtedness or Debenture
Specified Senior Indebtedness, as the case may be will be able to prevent
payments on the Senior Subordinated Notes or Debentures, as the case may be, for
certain periods of time. See "Description of the Notes--Ranking." However, while
the Senior Subordinated Notes Indenture and the Debenture Indenture (which
govern the terms of subordination) is governed by the laws of the State of New
York, there can be no assurances that a bankruptcy court in Thailand will give
effect to such contractual subordination.
 
NTS PLEDGE; SUBSTANTIAL OWNERSHIP BY PLEDGEE OR SUCCESSOR
 
    N.T.S. Steel Group Public Company Limited ("NTS"), a steel rebar
manufacturer and an affiliate of the Company, currently holds 31.31% of the
outstanding ordinary shares of the Company. The Thailand Securities Depository
Company Limited, the Company's registry has confirmed that NTS has pledged
30.54% of NSM's outstanding shares (the "Pledged Shares"). The Company believes
that NTS has pledged such shares to certain Thai financial institutions as
security for indebtedness owed to such financial institutions. The Company
believes that NTS is currently in default on its obligations under such
indebtedness.
 
    Under the laws of Thailand, the pledge of the Company's ordinary shares may
be enforced by way of public auction. Alternatively, after the debt is due, the
pledgor and pledgee may agree that the pledgee will become owner of the pledged
shares in full or partial satisfaction of the debt. However, as a condition of
being listed on the SET, the shares held by NTS, as well as certain shares held
by some of the Company's management and major shareholders totaling 55% of NSM's
paid-in capital without giving effect to the Offerings, are subject to SET
restrictions which prevent transfer of the shares during the first year of the
Company's commercial operations. In addition, in the case where the Company
issues and offers new shares for sale to its existing shareholders during the
said first year, those shares subscribed by the Company's management and major
shareholders will also be subject to a transfer restriction. Since the offering
of new shares on the Issue Date was not made to the Company's existing
shareholders, those new shares are not subject to such transfer restriction.
Currently, after giving effect to the Offerings, only 42.86% of NSM's paid-in
capital are subject to transfer restriction for the first year. According to the
SET's regulation, a pledgee which is a financial institution must enter into an
agreement with the shareholder, whose ownership is subject to the SET
restriction, that it will not enforce pledged shares subject to such restriction
during the applicable period. Such pledgee is required to submit a letter to the
SET stating that it has entered into such an agreement with the pledgor. Any of
the Pledged Shares which were pledged to finance companies whose operations were
suspended by the Ministry of Finance may be sold at public auction by the
Financial Restructuring Authority. Persons acquiring the Pledged Shares would
have full rights in such Pledged Shares and would not be restricted in the
exercise of such rights by the Shareholders' Agreement (as defined) to be
entered into by the New Equity Investors and certain Thai parties. See
 
                                       24

"Principle Agreements--Shareholders Agreement." Even after giving effect to the
dilution caused by the Warrants, if one person, group or entity were to acquire
all or a substantial portion of the Pledged Shares, such person, group or entity
is likely to be the single largest shareholder in the Company. While management
of the Company will be governed by the Management Agreement, such a shareholder
would, under the laws of Thailand, have the ability to influence the conduct of
business by the Company. For example, such a shareholder would have the ability,
among other things: (i) to require the board of directors of the Company to
convene a shareholders meeting; (ii) to substantially influence the outcome of
any shareholder vote; (iii) to block any action by the Company that would
require the approval of a supermajority (75%) of the Company's shares, present
at the shareholder meeting, under the laws of Thailand; and (iv) to influence
the election of directors to the Company's board of directors. There can be no
assurance that any future acquiror of the Pledged Shares will exercise its
rights with respect to the Pledged Shares in a manner consistent with the
intentions of the Company and the New Equity Investors for the future conduct of
business by the Company as set forth herein. If such an acquiror of the Pledged
Shares exercises its rights with regard to the Pledged Shares in a manner
inconsistent with the intentions of the Company and the New Equity Investors for
the future conduct of business by the Company there can be no assurance that
such inconsistent exercise will not have an adverse effect on the financial
condition and results of operations of the Company or its ability to repay its
indebtedness including the Securities.
 
FORWARD LOOKING INFORMATION
 
    This Prospectus contains forward-looking statements. These statements are
based upon the current beliefs of the Company as well as assumptions made by the
Company based upon information currently available to it.
 
    These statements are subject to various risks and uncertainties, including
those described above, as well as potential changes in economic or regulatory
conditions which are largely beyond the Company's control. Should one or more of
these risks materialize or changes occur, or should management's assumptions
prove incorrect, the Company's actual results may vary materially and adversely
from those anticipated or projected. These forward-looking statements reflect
the Company's views with respect to future events and financial performance.
Actual results could differ materially from those projected in the
forward-looking statements as a result of many factors, including the risk
factors set forth above. The words, "believe," "expect" and "anticipate" and
similar expressions identify forward-looking statements. Prospective investors
or purchasers are cautioned not to place undue reliance on these forward-looking
statements, which speak only as of their dates. The Company undertakes no
obligation to publicly update or revise any forward-looking statements, whether
as a result of new information, future events or otherwise.
 
NO ASSURANCE OF ADEQUATE COLLATERAL; SHARED COLLATERAL; ABILITY TO REALIZE ON
  COLLATERAL
 
    The Notes are secured by a first priority pledge of the capital stock of NSM
(Del). The Debentures will be secured by a second priority pledge of the capital
stock of NSM (Del). The Guaranties (other than the Debenture Guaranty) will be
secured by a first priority pledge of the share capital of NSM Cayman and the
other Collateral. The Collateral will also secure, on an equal and ratable
basis, the obligations of the Company under the Bank Credit Facility (other than
the Offshore Reserve Account, the Notes DSR Account, and the pledge of the share
capital of NSM Cayman) and, on a second priority basis, the obligations of the
Company in respect of the Debenture Guaranty. Pursuant to the terms of the Bank
Credit Facility, the Company has agreed that, other than as a result of
enforcement of the security interests granted in the Collateral, in the event
that there are insufficient funds available at any time to make all payments of
principal or interest then due under the Bank Credit Facility, the Notes and the
Debentures, it will pay 100% of any interest and 50% of any principal then due
under the Bank Credit Facility prior to paying any interest then due on the
Notes or the Debentures.
 
                                       25

    A significant portion of the Collateral is shared on an equal and ratable
basis by the holders of the Notes and the parties to the Bank Credit Facility
and, on a second priority basis, the holders of the Debentures. The agreement
governing intercreditor issues with respect to the Collateral provides that
rights will be based on principal amounts outstanding under the Notes and the
Bank Credit Facility. The rights of the holders of Senior Subordinated Notes are
limited so that such holders may not have, during the pendency of a Default
under the Senior Note Indenture, the ability to take enforcement action in
respect of the Collateral or otherwise exercise voting rights in connection with
the Collateral. See "Risk Factors--Ranking of the Senior Subordinated Notes and
Senior Subordinated Guaranty; Limitations on Enforcement of Collateral." The
Company has entered into an agreement with the lenders under the Bank Credit
Facility as to the sharing of rights in the Collateral, including inter-creditor
rights in the Collateral, on terms substantially similiar to those described in
this Prospectus.
 
    In addition, there can be no assurance that the proceeds of any sale by the
Collateral Agent of the Collateral following a default would be sufficient to
satisfy payments due on the Guaranties, especially given that the holders of the
Securities must share their Collateral interests. If such proceeds were not
sufficient to repay all such amounts due on the Guaranties and under the Bank
Credit Facility, then holders of the Guaranties (to the extent not repaid from
the proceeds of the distribution of the Collateral) would have only an unsecured
claim against the Company's remaining assets. There can be no assurance that the
Company's remaining assets would be sufficient to satisfy all unsecured claims
in full or that any such assets would exist. The value of the Collateral in the
event of a liquidation will depend on market and economic conditions, the
availability of buyers and other factors beyond the Company's control. Moreover,
the assets of the Company, if taken and sold individually, would be likely to
result in the receipt of proceeds that are less than the proceeds realizable in
connection with a sale of the business of the Company as a going concern. It is
likely that the Collateral Agent might also seek to sell the Mill and operations
substantially as a whole operation in order to maximize proceeds realized
therefrom. However, the ability of the Collateral Agent to elicit purchasers for
any assets which are subject to the security or the price obtained upon sale or
transfer may be limited or affected by termination rights under the material
contracts.
 
    An arrangement has been effected whereby, in the event enforcement of the
mortgage of the Company's assets in Thailand becomes necessary, the Collateral
Agent will become the registered owner of the Notes and will thereby have
standing to bring an enforcement action in a Thai court. There can be no
assurance that such arrangement will be effective or will be ultimately upheld
in an actual enforcement action. In the event that the standing of the
Collateral Agent to bring an enforcement action were not recognized by a Thai
court, there can be no assurance that holders of the Notes would enjoy the
benefit of their respective security interest in the manner described therein.
See "--Book Entry Interests; Dependence on Intermediaries."
 
    As a result of all of the foregoing, holders of the Securities could face
significant difficulties in enforcing their rights to the Collateral in the
event of a default under the Securities or in collecting sufficient amounts upon
a disposition of such Collateral. If any of the foregoing were to adversely
effect the arrangements in respect of the Collateral, the Securities and
Guaranties could represent only unsecured claims against the Company's assets.
 
ENFORCEMENT OF THE MORTGAGES
 
    Under Thai law, a mortgage will be invalid until it is registered with the
Provincial Land Office in which the property is located. Such a mortgage extends
to all permanent fixtures and buildings on the land but it does not accord
mortgage rights over buildings erected on the land after the date the mortgage
is registered unless so provided in the mortgage application.
 
                                       26

    The Company will also seek to register a mortgage in favor of the parties to
the Bank Credit Facility and the Collateral Agent for all machinery located at
the Mill. According to the Thai Machinery Registration Act, such a mortgage may
only be registered after the import and installation of the machinery. As of the
Issue Date, no machinery of the Company has been registered pursuant to the
Machinery Registration Act. The Company's application for registration is
pending approval with the relevant authorities. The registration process can be
time consuming. In the interim, and for machinery and equipment that does not
qualify for registration under the Machinery Registration Act, a security
interest in such machinery and equipment will be granted pursuant to a pledge in
favor of the parties to the Bank Credit Facility and the Collateral Agent.
According to the Security Documents, the pledgee will appoint a custodian to
possess the pledged machinery. Under Thai law, a pledge is valid only if the
pledged property is in the possession of the pledgee or a third party custodian.
The validity of an arrangement such that the pledgee appoints a custodian to
possess the pledged property which is left at pledgor's plant has not been
tested by Thai courts. Under the pledge agreement and the Security Sharing
Agreement, the Company is obligated to (i) register all Registrable Machinery
(as defined) at the Mill; and (ii) cause the existing pledge to be converted to
a mortgage in favor of the holders of the Notes, the Bank Credit Facility and,
on a second priority basis, the Debentures.
 
    A mortgage, whether it be for land and buildings or machinery, is
enforceable in Thailand only upon order of a court judgment and sale at a public
action, unless (i) interest has been unpaid for five years or more, (ii) the
mortgagor cannot satisfy the court that the value of the property exceeds the
amount due, and (iii) there are no other mortgages or preferential rights
registered on the same property, in which case, foreclosure is possible.
 
    To enforce a mortgage in Thailand, the mortgagee must first issue a notice
to the debtor giving them a reasonable time to satisfy the debt. In the event
the debt cannot be repaid within this timeframe, the mortgagee may file an
action in a court with jurisdiction over the location where the mortgage has
been registered seeking to declare the debtor in default and order the
collateral to be sold at public auction. Once an order is obtained, the court
will order a public auction to be held at which time the property will be sold
to the highest bidder. See "Security Arrangements."
 
    Current Thai law on the enforcement of mortgages may be impacted by the
recently enacted amendment to the bankruptcy law. There has been an attempt to
amend the laws in order to speed up the enforcement procedures. For example, the
sale by public auction of mortgage property can be made with a judicial order.
See "Risk Factors--Thai Bankruptcy--New Business Reorganization Proceedings."
 
WITHHOLDING TAXES
 
    The Company will make payments to the Note Issuers on terms, in amounts and
on dates so that the Note Issuers may make interest payments to holders on the
Securities. Such payments by the Company to the Note Issuers may be subject to
withholding tax at a rate of 15%. While the Company intends to structure its
payments to the Note Issuers to substantially reduce the effect of such
withholding, there can be no assurance that such measures will prove successful
in reducing the application of withholding taxes. If such measures are
unsuccessful withholding tax may be applied to payments from the Company to the
Note Issuers. The application of such withholding taxes would have an adverse
effect on the financial condition and results of operations of the Company and
may have an adverse effect on the ability of the Company to fund the Issuers'
interest payment obligations on the Notes.
 
BOOK-ENTRY INTERESTS; DEPENDENCE ON INTERMEDIARIES
 
    Until and unless Definitive Securities are issued in exchange for the
Book-Entry Interests, holders of the Book-Entry Interests will not be considered
the owners or holders of Securities under the Indentures. After payment to the
Book-Entry Depositary, the Note Issuers or the Company, as the case may be, will
have no responsibility or liability for the payment of interest, principal or
other amounts to DTC or to
 
                                       27

holders of Book-Entry Interests. The Book-Entry Depositary, or its nominee, will
be the sole holder of the Securities in the form of the Global Notes.
Accordingly, each person owning a Book-Entry Interest must rely on the
procedures of the Book-Entry Depositary and DTC, and, if such person is not a
participant in DTC, on the procedures of the participant through which such
person owns its interest (including, if applicable, the Euroclear Operator or
Cedel), to exercise any rights of a holder under the Indentures.
 
    Payments of principal and interest on, and other amounts due in respect of,
the Global Securities will be made to the Book-Entry Depositary (as holder of
the Global Securities), which will in turn distribute payments to Cede & Co. (as
nominee of DTC). DTC, upon receipt of any payment from the Book-Entry
Depositary, will promptly credit participants' accounts with payments in amounts
proportionate to their respective ownership of Book-Entry Interests, as shown on
the records of DTC. The Note Issuers expect that payments by participants or
indirect participants to owners of interests in Book-Entry Interests held
through such participants or indirect participants will be governed by standing
customer instructions and customary practices, as is now the case with the
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such participants or indirect
participants. None of the Note Issuers, the Company, the Trustee, the Book-Entry
Depositary, any Paying Agent or the Registrar will have any responsibility or
liability for any aspect of the records relating to, or payments made on account
of, the Book-Entry Interests or for maintaining, supervising or reviewing any
records relating to such Book-Entry Interests.
 
    Unlike holders of the Securities themselves, holders of the Book-Entry
Interests will not have the direct right under the Indentures to act upon
solicitations by the Note Issuers of consents or requests by the Note Issuers
for waivers or other actions from holders of the Securities. Instead, a holder
of Book-Entry Interests will be permitted to act only to the extent it has
received appropriate proxies to do so from DTC and, if applicable, DTC
participants. There can be no assurance that procedures implemented for the
granting of such proxies will be sufficient to enable holders of Book-Entry
Interests to vote on any requested actions on a timely basis. Similarly, upon
the occurrence of an Event of Default under the Securities, holders of
Book-Entry Interests will be restricted to acting through DTC and the Book-Entry
Depositary if and until such Holders request Definitive Securities to be issued.
There can be no assurance that the procedures to be implemented by DTC and the
Book-Entry Depositary under such circumstances will be adequate to ensure the
timely exercise of remedies under the Indentures. For a description of the terms
of the Note Depositary Agreement, see "Note Depositary Agreement; Delivery;
Form".
 
CYCLICALITY OF STEEL INDUSTRY AND END USER MARKETS
 
    The steel industry is highly cyclical in nature and sensitive to general
economic conditions. The price of steel and steel products in the future may
fluctuate significantly as a result of general economic conditions and other
factors beyond the Company's control. The demand for steel products and, thus,
the financial performance of companies in the steel industry, including the
Company, are generally affected by macroeconomic fluctuations in domestic
economies in which these companies sell their products as well as in the world
economy. Substantially all of the revenues of the Company are derived from the
sale of steel and related products. Accordingly, any significant decrease in
demand for steel and related products or decline in prices for such products
could have a material adverse effect on the business, financial condition,
results of operations or prospects of the Company. The Company's success will be
influenced by a number of market factors, both international and domestic, which
affect the market for steel products and steel scrap (initially the Company's
principal raw material), and which are beyond the control of the Company. There
can be no assurance that the deterioration in the economies of Thailand and
Southeast Asia will not have an adverse effect on the domestic, regional and
global markets for the Company's products. The Company is particularly sensitive
to trends in the oil and gas, gas transmission, construction, commercial
equipment, automotive, rail transportation, agriculture and durable goods
industries, because these industries are significant markets for the Company's
products and are highly cyclical.
 
                                       28

COST OF STEEL SCRAP AND OTHER RAW MATERIALS
 
    The Company requires substantial amounts of raw materials, principally iron
ore fines, iron ore pellets and scrap, in its production process. Until the DRI
Facility is operational, the Company's principal raw material will be steel
scrap. The prices for scrap are subject to market forces largely beyond the
control of the Company, including demand by domestic and international steel
producers, freight costs and speculation. The prices for scrap have varied
significantly and may vary significantly in the future. In addition, the
Company's operations may require substantial amounts of other raw materials and
utilities, including various types of pig iron, DRI, alloys, refractories,
oxygen, natural gas and electricity, the price and availability of which are
also subject to market conditions. Although the Company believes that raw
materials are available in adequate quantities at market prices the availability
and prices of raw materials may be subject to curtailment or changes due to,
among other things, new laws or regulations, suppliers' allocations to other
purchasers, interruptions in production by suppliers, changes in exchange rates
and worldwide price fluctuations. In addition, energy costs, including the cost
of natural gas and electricity, also constitute a substantial portion of the
Company's cash cost of production. The price of some of the Company's production
inputs, particularly energy, have varied significantly and may vary
significantly in the future largely as a result of market conditions and other
factors beyond the control of the Company. Any protracted interruption in the
supply of raw materials or energy, or substantial increases in their costs,
could have a material adverse effect on the business, financial condition,
results of operations or prospects of the Company. The Company may not be able
to adjust its product prices, especially in the short term, to recover any
increases in scrap and other raw material prices. The Company's future
profitability may be adversely affected to the extent that it is unable to pass
on higher raw material and energy costs to its customers. See "Management's
Discussion and Analysis of Financial Condition," "Business--Steel Scrap and
Scrap Substitute Resources" and "Energy Resources."
 
RISK RELATED TO PROCESS TECHNOLOGY
 
    The Company's process for the production of coal-based DRI is a scale-up
from a commercial steel industries wastes recycling plant, operated by
International Metals Reclamation Company, Inc. ("INMETCO"). The use of coal as a
reductant is made possible by special sulfur removing slag practices in NSM's
ladle metallurgy system. These slag practices and the INMETCO process have each
been used commercially. However, NSM will be the first company to link the two
processes and there can be no assurance that they will perform in accordance
with the Company's expectations.
 
COMPETITION
 
    The Company has various competitors within the global steel industry.
Generally, the markets in which the Company participates are highly competitive.
The competitive nature of the industry in the future could have an adverse
effect on the business, financial condition, results of operations and prospects
of the Company. The Company competes primarily on the basis of price, quality,
and the ability to meet customers' product specifications and delivery
schedules. Many of the Company's competitors are integrated steel producers
which are larger in terms of steel making capacity, have substantially greater
capital resources and historical operations and, in some cases, have lower raw
material costs than the Company. In addition, competition may increase as a
result of excess capacity created by other producers using mini-mill technology
and traditional steelmakers in order to make their operations more efficient.
For example, several new mini-mills began production in the United States in
1996 and 1997. The highly competitive nature of the global steel industry,
combined with excess production capacity in some products, may in the future
exert downward pressure on prices for the Company's products. The deterioration
in the economies of Southeast Asia may exert further downward pressure on prices
for the Company's products if regional competitors choose to lower their prices
in order to maintain revenues in the face of decreasing regional demand for
steel products. Although the Company believes that it is well-positioned to
compete in the markets where it operates, competitors may develop new products
or production processes that could
 
                                       29

provide advantages to such competitors to the detriment of the Company. There
can be no assurance that the Company will be able to compete effectively in the
future. In addition, in the case of certain product applications, steel competes
with other materials, including plastics, aluminum, graphite composites,
ceramics, glass, wood and concrete. See "Business--Competition."
 
DEPENDENCE ON KEY PERSONNEL AND MANAGEMENT
 
    The Company's success depends on its ability to attract, motivate and retain
highly skilled and qualified management and technical personnel to operate the
Mill. The Company's ability to maintain its competitive position is dependent to
a large degree on the services of its senior management team, particularly Mr.
John W. Schultes, President and Chief Executive Officer. The loss of Mr.
Schultes' services or those of any of the other members of the Company's senior
management team or an inability to attract, retain and maintain additional
senior management personnel could have a material adverse effect on the
business, financial condition, results of operations or prospects of the
Company. There can be no assurance that the Company will be able to retain its
existing senior management personnel or to attract additional qualified senior
management personnel. In addition, there can be no assurance that the Company
will be able to hire qualified persons when needed or on favorable terms or that
new employees will be successfully assimilated into the Mill's operations.
 
LABOR MATTERS
 
    The Company believes that its relations with its employees are good.
Nevertheless, there can be no assurance that a work stoppage or strike will not
occur. Work stoppages or other labor-related developments affecting the Company,
including the ability to attract and retain additional employees, could have a
material adverse effect on the business, financial condition, results of
operations and prospects of the Company.
 
RELIANCE ON MAJOR CUSTOMERS
 
    The Company has entered into the Off-Take Agreements with Preussag and
Klockner pursuant to which they have agreed to purchase up to 100% of the
Company's annual production during 1998 through 2002. Under the Off-Take
Agreements, steel will be sold based on quality and description specified by the
purchaser and be fit for the purpose for which such goods are ordinarily used.
Certain orders may also contain express or implied application requirements.
Non-compliance with such specifications could result in rejections and claims
against the seller. Such claims are usually settled between the producer, the
trading company and the end user. Claims may result in financial damage awards
against the Company. As a result, failure to perform under the Off-Take
Agreements by NSM may have a material adverse effect on the Company's results of
operations and financial condition. Additionally, non-performance by Preussag or
Klockner under the Off-Take Agreements could have a material adverse effect on
the Company's results of operations and financial condition. See "Description of
Material Agreements--Off-Take Agreements."
 
DEPENDENCE UPON A SINGLE PROJECT
 
    Virtually all of the Company's revenue will be derived from the Mill. The
operations of the Mill are subject to the risks normally encountered in steel
production. Such risks include environmental hazards, industrial accidents,
technical difficulties or failures, labor disputes, late delivery of supplies,
and periodic or extended interruptions due to inclement or hazardous weather
conditions, fires, explosions or other accidents or acts of force majeure. Such
risks could result in damage to or destruction of producing facilities, personal
injury, environmental damage, delays in production, losses and possible legal
liability. Any prolonged downtime or shutdowns at the Mill could materially
adversely affect the Company's financial performance and ability to repay the
principal and interest on the Notes.
 
                                       30

INSURANCE
 
    The Company maintains insurance coverage within ranges comparable to other
steel producers. There can be no assurance that such insurance will be available
to the Company in the future on commercially reasonable terms or that any
coverage the Company arranges will be adequate and available to cover any or all
claims which arise. Insurance against environmental risks (including potential
liability for pollution or other hazards as a result of disposal of waste
products occurring from steel production) is not generally available to the
Company or to other companies within the steel industry. To the extent that the
Company is subject to environmental liabilities, the payment of such liabilities
would reduce the funds available to the Company to operate the Mill. The Company
cannot reasonably estimate the cost of future compliance or remedial work or
further investments that may be required as a consequence of changes in
environmental regulation. Among other things, the level of such costs will be
dependent upon the nature and extent of the current and future environmental
regulation, the timing and nature of required or remedial work and the
technology available to meet the required standards. Should the Company be
unable to fund fully the cost of remedying an environmental problem, the Company
might be required to suspend operations or enter into interim compliance
measures pending completion of the required remedy.
 
REDUCTION OF IMPORT TARIFFS
 
    Thailand currently imposes a tariff on steel imports at the rate of 1% on
iron-ore, pig-iron and scrap; 10% on billets and slabs; 15% on hot-rolled coil;
20% on coated products and cold-rolled products. Thailand is a signatory to the
Uruguay Round of Agreements, under which the signatories have agreed to
eliminate import tariffs on many products and significantly reduce non-tariff
barriers to trade. Pursuant to the Uruguay Round of Agreements of the General
Agreement on Tariffs and Trade, certain developed countries have agreed to
eliminate import tariffs on steel products within 10 years. Although Thailand
has not formally agreed to eliminate its import tariff on steel products, it has
agreed not to increase its import tariff on certain steel products, to greater
than 30%. Additionally, the Association of Southeast Asian Nations ("ASEAN") has
stated its goal to reduce tariffs on steel products to 0-5% by the year 2003
under the ASEAN Free Trade Agreement for imports from ASEAN nations. There is no
guarantee that Thailand will not reduce its import tariff on steel products over
the next few years to conform with the trend towards a more open global market.
A significant reduction in or the elimination of the tariffs on the import price
of steel would lead to increased competition from international producers of
steel as well as a decreased pricing advantage for the Company's steel products
in Thailand and could have an adverse effect on the Company's financial
condition and results of operations.
 
GOVERNMENT APPROVALS AND REGULATION
 
    Government approvals and permits are currently, and may in the future be,
required in connection with the Company's operations. The Company obtained
waivers from the Bank of Thailand which would allow the Company to keep certain
revenues offshore and would prevent certain U.S.$ funds in Thailand from being
converted into Baht. Obtaining the necessary governmental approvals, permits and
waivers is a complex and time consuming process involving numerous regulatory
agencies. To the extent that such approvals or permits are required and not
obtained, operations may be curtailed or limited and such curtailment or
limitation could have an adverse effect on the Company's financial condition and
results of operations.
 
    The Company's business is currently regulated by the laws and regulations of
Thailand relating to the construction, production, marketing, pricing,
transportation and storage of steel products, taxation, environmental and safety
matters. The Company does not believe that environmental regulations will have a
material adverse effect on its capital expenditures, results of operations or
competitive position, and does not anticipate that any material expenditures
will be required to enable it to comply with existing laws and regulations.
However, the modification of existing laws or regulations or the adoption of new
laws or
 
                                       31

regulations pertaining to steel manufacturing for economic, environmental or
other reasons could have a material adverse effect on the Company's financial
condition and results of operations.
 
    The Company's assets and operations are subject to various political,
economic and other uncertainties, including, among other things, the risks of
war, expropriation, nationalization, renegotiation or nullification of existing
concessions and contracts, taxation policies, foreign exchange and repatriation
restrictions, changing political conditions, fluctuations between the Baht and
the U.S.$, currency controls and foreign governmental regulations. The Company
may also be hindered or prevented from enforcing its rights with respect to a
governmental instrumentality because of the doctrine of sovereign immunity.
 
BOARD OF INVESTMENT COMPLIANCE
 
    The Company derives substantial economic benefits from the promotional
considerations granted to it by the Board of Investment ("BOI"). Such benefits
include the permission to bring foreign experts into Thailand and the exemption
from certain import duties and taxes. While the BOI has only granted two
licenses to produce steel in Thailand, there can be no assurance that the BOI
will not grant additional licenses to potential domestic competitors in the
future. The continued availability of these economic benefits for the Company is
conditional upon the on-going satisfaction of certain requirements, including a
limitation on foreign ownership to 49% of the outstanding equity of NSM. The
limitation on foreign ownership is increased to 39% in connection with the
benefits granted by the BOI on the Finishing Facilities. Failure to satisfy
these requirements may result in the loss of economic benefits which may have an
adverse effect on the Company's financial condition and results of operations.
The granting of licenses for the production of steel products in Thailand to
other potential domestic competitors could also have an adverse effect on the
Company's financial condition and results of operations. See "Business--Board of
Investment."
 
POTENTIAL CONFLICTS OF INTEREST; AFFILIATE TRANSACTIONS
 
    Under Thai law, a director of a public company is prohibited from owning,
operating or serving as a director of a business of the same nature as, and
competitive with, the company of which he or she is a director unless he or she
informs the shareholders of the company at a meeting of shareholders prior to
his or her appointment or accession to ownership (if the shareholders do not
approve the director's other activities, they can cause the director to resign
or cause the company to pursue other remedies). A number of the directors of the
Company hold interests in or are officers or directors of companies engaged in
various aspects of the steel industry. The Company believes that such directors'
endeavors have been in compliance with the foregoing provision of Thai law.
However, Thai law may be more limited than that of many other jurisdictions in
limiting directors of a company in pursuing corporate opportunities which might
have been of interest to the company if presented to the company. Therefore, in
light of this provision and the other interests of a number of directors of the
Company (such as the Chairman of the Company and other members of his family who
currently sit on the Company's board of directors and also maintain interests in
other companies), the Company may be limited as to the number and type of
corporate opportunities which are presented to it in the future. See
"Management."
 
    Several of the directors of the companies have direct and/or indirect
investments in affiliated companies. In addition, some of these companies also
have direct and indirect investments in each other. A number of arrangements and
transactions have been entered into from time to time between such companies.
Under corporate law in Thailand, directors of a company are required to act at
all times in the best interests of the shareholders with respect to transactions
entered into by the company. In addition, corporate law in Thailand places
certain limitations on the ability of a public company to enter into related
party transactions. See "Related Party Transactions."
 
    Because of the scope of the relationships that exist between the companies
there can be no assurance that such agreement or transactions entered into, if
considered separately, have been or will be effected on
 
                                       32

terms no less favorable to the Company than could have been obtained from
non-associated third parties. Such transactions could have an adverse effect on
the Company's financial condition and results of operations. While any future
arrangements are expected to be subject to approval by the Company's board of
directors and, where appropriate, the approval of shareholders, there can be no
assurance that the future arrangements between the Company and the other
associated companies will not involve conflicts of interest.
 
THAI BANKRUPTCY LAW
 
    CURRENT BANKRUPTCY LAW.  The Bankruptcy Act was enacted in 1940 and provides
for the liquidation of an insolvent company. A bankruptcy proceeding is
initiated by a creditor filing a petition for a court order to control the
property of the insolvent company, which will lead to the liquidation of the
company unless the creditors are able to negotiate a settlement. A company
cannot initiate proceedings voluntarily. There is no separate bankruptcy court,
and cumbersome civil procedure rules govern the proceedings. There are no
restrictions on the enforcement of security by secured creditors.
 
    After the court order controlling the property, a receiver (who is an
officer of the Ministry of Justice) is appointed. Creditors must file claims
within two months, and this period may be extended another two months for
foreign creditors. Foreign creditors must provide proof of reciprocity. Secured
creditors may elect to proceed to enforce their security, or to file claims
subject to restrictions in the Bankruptcy Act. Other than secured claims and
certain preferential rights, almost all other creditor claims have the same
general priority. There is a provision for a creditors' committee composed of
creditors which have filed claims to consider any composition of debts which may
be proposed.
 
The receiver may set aside the following transactions involving the company:
 
    - transactions effected within three years, unless the transferee can prove
      it was made in good faith and for consideration.
 
    - transactions effected within three months, if made with an intent to give
      undue preference to a creditor.
 
    - fraudulent transactions which prejudices other creditors.
 
    The receiver disposes of the assets of the company by public auction, and
distributes the net proceeds on a pro rata basis to all unsecured creditors,
according to a distribution schedule approved by the court. Although this
distribution is required by the Act to occur within six months of the
commencement of proceedings, in practice it takes years to complete the
liquidation proceedings.
 
    NEW BUSINESS REORGANIZATION PROCEEDINGS.  The following summary is based on
the amendment to the Bankruptcy Act (the "Bankruptcy Amendment") effective as of
April 10, 1998, by adding a chapter on reorganization proceedings to facilitate
the financial rehabilitation of insolvent companies.
 
    The Bankruptcy Amendment introduces a reorganization proceeding similar to
that under Chapter 11 of the U.S. Bankruptcy Code and to administration under
the Insolvency Act of 1986 in the United Kingdom. Such proceeding commences when
the court makes an order to that effect, following a hearing to consider a
request for a reorganization proceedings. Such request may be filed by the
company on a voluntary basis, by a creditor with a claim in excess of 10 million
Baht, or by certain regulatory agencies of the government. The request must
include basic information about the business of the Company and the prospects
for its rehabilitation.
 
    If the court issues an order to commence a reorganization proceeding, a
receiver is appointed and creditors (both secured and unsecured) must file their
claims within one month. Claims denominated in foreign currency must be
converted to Thai currency at the exchange rate on the date of the court order,
for the purpose of determining voting rights. The court order brings into effect
provisions which suspend litigation against the company, enforcement of security
by secured creditors unless otherwise ordered by
 
                                       33

courts, revocation of licenses by government authorities, and other protections
to aid reaching a successful outcome of the reorganization proceeding.
 
    After the court issues its order, the company's management is divested of
its powers to run the business, and that power is transferred initially to a
receiver. There is a procedure to appoint a plan preparer by the court or by
general resolution of a meeting of creditors. If the Company nominates a plan
preparer; such person shall become the plan preparer unless otherwise provided
by a two-thirds majority amount of voting debt. Before a plan preparer is
appointed, all legal rights of shareholders, except for the right to receive
dividends, shall cease as rights of the shareholders and become rights of the
receiver or temporary management. The plan preparer, or the receiver, assumes
responsibility for management of the company. The plan preparer also has a duty
to formulate a reorganization plan within prescribed time frames. The plan will
include an arrangement for the payment of creditor claims, in whole or in part,
and a description of the steps necessary to rehabilitate the business and the
period thereof which shall not exceed 5 years. The creditors who are eligible to
file their claims and are debtors of the Company at the time the court orders
rehabilitation, may set-off their debts against the Company's debts. A special
resolution (75% vote) of the creditors is required to approve the plan and to
form a committee to monitor its implementation. Once the court approves the
plan, the rights and duties of the plan preparer pass to the plan administrator.
 
    The Bankruptcy Amendment does not include any provision for the
establishment of a separate bankruptcy court in Thailand. Some time will be
required to assess the capability of the civil court to handle complicated
reorganization, and for professions of plan preparers and plan administrators to
develop. In comparison to corporate reorganization proceedings under Chapter 11,
the proposed new Thai reorganization proceeding will present some major
differences, for example:
 
    - all creditors vote on the proposed reorganization plan by "special
      resolution", and there is no provision for creditor classification or
      class voting as in a Chapter 11 case.
 
    - following the court order to initiate a reorganization proceeding, the
      company loses its powers to manage the business, and there is no "debtor
      in possession" concept.
 
    - the Bankruptcy Amendment does not include a provision prohibiting
      non-debtors from terminating executory contracts.
 
    There is now an attempt to further amend the Bankruptcy Amendment. The
Cabinet recently approved the draft amendment two major proposals are (i)
establishing criteria for courts to consider in deciding whether to approve a
plan, (ii) providing for class voting and (iii) empowering the receiver to deny
executory contracts.
 
CHANGE OF CONTROL
 
    The Notes, the Guaranties and the Debentures require the Note Issuers and
the Company to make an offer to repurchase any and all outstanding Notes and
Debentures at a purchase price equal to 101% of the Accreted Value (as defined)
thereof, plus accrued and unpaid interest, if any, to the date of purchase, upon
the occurrence of a Change of Control. No repurchase of the Senior Subordinated
Notes will be made until the offer to repurchase the Senior Notes is completed.
No assurance can be given that the Issuers or the Company will have sufficient
funds to purchase any or all of the Notes or the Debentures following a Change
of Control. See "Description of Notes and Guaranties--Repurchase at the Option
of Holders-- Change of Control."
 
ABSENCE OF PUBLIC MARKET FOR THE SECURITIES
 
    The New Securities are new securities for which there currently is no
established trading market. The Initial Purchaser has informed the Company that
it intends to make a market in the New Securities to the extent permitted by
applicable laws and regulations. However, it is not obligated to do so and any
such
 
                                       34

market making may be discontinued at any time without notice in the sole
discretion of the Initial Purchaser. In addition, such market making activity
may be limited during pendency of the Exchange Offer or the effectiveness of a
shelf registration statement in lieu thereof.
 
    Accordingly, there can be no assurance as to the development or liquidity of
any market for the New Securities. The New Securities are expected to be
eligible for trading by qualified buyers in the PORTAL market. The Company does
not intend to apply for listing of the New Securities on any securities exchange
or for quotation through the National Association of Securities Dealers
Automated Quotation System ("NASDAQ").
 
    The liquidity of, and trading market for, the New Securities also may be
adversely affected by general declines in the market for similar securities.
Such declines may adversely affect such liquidity and trading markets
independently of the financial performance of, and prospects for, the Company.
 
PRE-OPERATING EXPENSES
 
    During the years ended December 31, 1995, 1996 and 1997, the Mill was under
construction and the Company had no operating revenues. Under Thai GAAP, the
Company capitalizes operating expenses incurred prior to beginning commercial
operations as deferred charges. Deferred charges will be amortized over a
10-year period commencing when revenues are earned from operations which will
result in lower reported earnings in future periods. Deferred charges as
reported under Thai GAAP and operating results as calculated under U.S. GAAP for
the Company from inception to December 31, 1997, are as follows (in thousands):

LACK OF ENFORCEMENT OF FOREIGN JUDGMENTS
 
    The Company and the Note Issuers, pursuant to the Indentures will have to
submit to jurisdiction under the laws of the State of New York. However, the
Company and the Note Issuers have been advised by their Thai legal counsel,
White & Case (Thailand) Limited that any judgment or order obtained in a court
outside Thailand, including the United States, would not be enforced as such by
the courts of Thailand, but such judgment or order in the discretion of the
courts of Thailand may be admitted as evidence of an obligation in new
proceedings instituted in the courts of Thailand, which would consider the issue
on the evidence before it. See "Enforceability of Civil Liabilities."
 
                                       35

                                USE OF PROCEEDS
 
    The Company and the Note Issuers will not receive any cash proceeds from the
Exchange Offers. In consideration for issuing the Securities as described in
this Prospectus, the Company and the Note Issuers will receive in exchange Old
Securities in like principal amount, the terms of which are identical in all
material respects to those of the New Securities, except that the New Securities
have been registered under the Securities Act and are issued free of any
covenant regarding registration, including the payment of additional interest
upon a failure to file or have declared effective an exchange offer registration
statement or to consummate the applicable Exchange Offer by certain dates. The
Old Securities surrendered in exchange for the New Securities will be retired
and cancelled and cannot be reissued. Accordingly, the issuance of the New
Securities will not result in any change in the indebtedness of the Company.

    The following table shows the capitalization of the Company as at December

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
 
    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE COMPANY'S
AUDITED FINANCIAL STATEMENTS AND CERTAIN FINANCIAL PROJECTION INFORMATION THAT
APPEAR ELSEWHERE IN THIS PROSPECTUS. SUCH FINANCIAL STATEMENTS HAVE BEEN
PREPARED IN ACCORDANCE WITH THAI GAAP, WHICH DIFFERS IN CERTAIN RESPECTS FROM
U.S. GAAP. SEE "SUMMARY OF CERTAIN DIFFERENCES BETWEEN THAI GAAP AND U.S. GAAP."
 
OVERVIEW
 
    The Company was formed in 1994 to develop a thin-slab/flat-rolled steel
mini-mill in Thailand to serve the domestic and world steel markets.
 
    Construction of the Hot Mill began in August 1995. Operational testing of
the tunnel furnace and the rolling mill, key components of the Hot Mill, began
in October 1997 when the Company rolled its first coils from purchased slabs.
Operational testing of the EAF and caster began in December 1997 when the
Company produced its first heat of molten steel which was successfully cast into
slabs and passed through the rolling mill to produce the first coil made
entirely in the Hot Mill. Commercial operations of the Hot Mill began in the
first quarter of 1998. Upon completion of the Hot Mill and commencement of
commercial operations, the Company began to depreciate Hot Mill property, plant
and equipment and amortize related deferred charges.
 
    The Company has begun to construct the DRI Facility to provide a reliable
supply of low-cost raw materials to supplement steel scrap in its melt mix. The
Company has begun to construct the Finishing Facilities to produce a wide array
of value-added products such as pickled and oiled, cold-rolled and galvanized
hot-and cold-rolled products. These value-added products are expected to produce
higher profit margins and reduce the Company's exposure to the volatility of
commodity grade steel prices. The Company will capitalize interest and
pre-operating costs related to the DRI Facility and the Financing Facilities
until these facilities commence operations.
 
    The Company generated its first revenue in the first quarter of 1998. Total
production was 20,587 tonnes which is below the Company's expectations. The
primary factors causing production delays have been shortages of raw materials
caused by a lack of funds for working capital and a general slowdown in
construction of the Mill prior to the completion of the Offerings. Also, the
ramp-up of production has been slowed due to inadequate commissioning support
and slowed delivery of spare parts from key equipment vendors. When the proceeds
of the Offerings became available the Company resumed purchasing raw material
and construction and equipment vendors were paid amounts due. As a result, the
pace of the start-up of the Hot Mill and construction of the DRI and Finishing
Facility improved dramatically. Production has been interrupted by liquid steel
breakouts caused by unforeseeable problems with refractory materials. The
Company and its refractory vendors have procured new refractory material and
altered refractory handling practices to prevent these problems from occurring
in the future. The Company expects production to reach planned levels during the
second half of 1998.
 
    Steel prices in Thailand specifically and in East and in Southeast Asia in
general have declined recent months as a result of the economic turbulence in
the region. As a result, the Company may have difficulties in reaching expected
levels of revenue in the near term. The Company expects steel prices to recover
as the economies of East and Southeast Asia nations stabilize.
 
GENERAL
 
    The Company's financial statements and the notes thereto as included in this
Prospectus reflect the financial condition of the Company as at December 31,
1994, 1995, 1996 and 1997.
 
    The majority of the Company's long-term debt and related interest expense is
denominated in U.S.$ (see Note 14 to the Audited Financial Statements and
"Description of Other Indebtedness"). Pursuant to Thai GAAP, the balance of such
debt is translated into Baht at period-end exchange rates. Because the
 
                                       39

Company's U.S.$ denominated debt is associated with the construction of the
Mill, any unrealized foreign exchange gains or losses incurred prior to start-up
of the Mill are capitalized as property, plant and equipment. Subsequent to
completion of the Hot Mill unrealized foreign exchange gains and losses incurred
on debt allocated to the Hot Mill will be recognized in the Company's income
statement. The company will continue to capitalize unrealized foreign exchange
gains and losses related to debt which has been allocated to construction of the
DRI Facility and Finishing Facilities.
 
    Although Thailand's economy has been characterized by high growth rates, in
1996 and particularly in 1997 GDP growth slowed significantly in relation to
historical levels. In late 1996 and in 1997 Thailand experienced significant
economic weakness, resulting primarily from declines in the property and finance
industries, a sharp reduction in financial liquidity and a general deterioration
in investor confidence. The deteriorating economy in Thailand is likely to
result in a significant portion of the Company's potential domestic customers
experiencing financial difficulty. Further, the Company expects that the number
of bankruptcies in Thailand and East and Southeast Asia generally, including
among its potential customers, will increase. The Company believes that the
significant devaluation of the Baht and other Asian currencies during the second
half of 1997 will reduce domestic and regional demand for its products.
Specifically the devaluation of the Korean Won and the Japanese Yen will impact
the Company's competitive position. Korea and Japan are the main steel producing
nations in the region.
 
    Changes in exchange rates will affect the Company's results of operations.
Substantially all of the Company's export sales are denominated in U.S.$ and its
domestic prices, which are denominated in Baht, are generally based on
international U.S.$ prices. The Company's operating costs are primarily
denominated in Baht and in U.S.$. As noted above, most of the Company's long
term debt and interest expense is denominated in U.S.$. Therefore, the Company's
financial results may be materially affected by both realized and unrealized
foreign exchange gains and losses.
 
    On July 2, 1997, the Ministry of Finance announced the adoption of a
"managed float" basis for determining the Baht exchange rate, resulting in an
immediate effective devaluation of the Baht. See "Risk Factors--Exchange Rate
Fluctuations". The value of the Baht, as reflected in the Noon Buying Rate,
declined from 24.520 Baht per U.S.$1.00 on July 1, 1997 to 46.80 Baht per
U.S.$1.00 on December 31, 1997. The Noon Buying Rate was 39.60 Baht per
U.S.$1.00 on March 31, 1998. There can be no assurance that the value of the
Baht will not decline further, increase or continue to fluctuate widely against
other currencies in the future. The Company believes that a devaluation of the
Baht, in general, tends to have a beneficial effect on its operating expenses
and capital costs. Adverse economic conditions in Thailand incidental to the
devaluation of the Baht, however, could reduce overall demand for the Company's
products and the Company's customers' ability to pay for them. See "Risk
Factors--Political and Economics Factors." The Company from time to time may
hedge its currency positions to attempt to avert any adverse consequences of
exchange rate exposure at a satisfactory cost.
 
    On January 6, 1998, the Ministry of Finance issued a regulation to limit the
U.S.$ holding period for exports in an effort to curtail currency speculation
and increase the U.S.$ supply in the local economy. According to the ministerial
regulation, exporters must now bring their earnings into Thailand immediately
upon payment, but in no event more than 120 days from the date of export after
which, they have seven days to either sell to or deposit their dollars in a
foreign currency account with an authorized commercial bank in Thailand.
Previously, the Bank of Thailand provided that exporters had 120 days in which
to receive payment for their goods and bring the money into the country, after
which they had a further 15 days to deposit it.
 
    The Company has obtained waivers from the Bank of Thailand which allow the
Company to (i) maintain a portion of the proceeds of export sales in U.S.$ in
bank accounts outside of Thailand; and (ii) maintain U.S.$ in bank accounts in
Thailand in an amount not to exceed the Company's foreign currency obligations
payable within three months. Failure by the Company to maintain these waivers
would force the Company to repatriate a substantial portion of its export
revenue to Thailand and eventually
 
                                       40

convert such revenue in Baht. Such conversion would require the Company to bear
exchange rate risks as many of the Company's obligations, including payments on
the Notes, are U.S.$ denominated. If the Company is unable to maintain these
waivers, any devaluation of the Baht against the U.S.$ could have an adverse
effect on the Company's financial condition and results and could materially
impair the Company's ability to repay its U.S.$ obligations, including payments
on the Notes. See "Risk Factors--Currency Regulation."
 
    The economic environment in which NSM operates is affected substantially by
both BOI promotions granted to NSM and protective measures, such as import
tariffs imposed by the Thailand government. See "Business--Competition." These
factors influence the Company's results both directly (such as through
reductions in tax liabilities) and indirectly (such as by reducing the ability
of non-Thai steel producers to compete with the Company for sales in Thailand).
Generally, the benefits derived by the Company from these sources can be
expected to decline over time. However, the Company believes that, as its
operations mature, its reliance on such benefits will also be reduced. See "Risk
Factors--Board of Investment Compliance." The BOI granted the Company an
exemption from all corporate income taxes on income earned on the production of
hot-rolled steel for a period of seven years.
 
LIQUIDITY AND FINANCIAL CONDITION
 
    The Company's business is capital intensive and requires substantial
expenditures for, among other things, the purchase and maintenance of equipment
used in its steelmaking operations and compliance with environmental laws. The
Company's liquidity needs arise primarily from capital investments, working
capital requirement and principal and interest payments on its indebtedness.
Since its inception, the Company has met these liquidity requirement with cash
provided by equity and long-term borrowings.
 
    In 1994, the Company issued 100,000 ordinary shares at par value of 100 Baht
per share for total gross proceeds of 10.0 million Baht. Later, the Company
changed is par value to 10 Baht per share and correspondingly adjusted the
number of ordinary shares to 1,000,000 ordinary shares. In 1995, the Company
issued 499,000,000 ordinary shares for gross proceeds of 5.14 billion Baht. In
1995, the Company registered itself as a public company and completed an initial
public offering in Thailand of 60,000,000 ordinary shares for gross proceeds of
960 million Baht in 1996.
 
    In September 1995, the Company obtained a senior credit facility from a
consortium of Thai financial institutions secured by all of the fixed the assets
of the Company (See Note 14 to the Audited Financial Statements). The facility
is composed of a 3.3 billion Baht tranche and a U.S.$308 million tranche which,
together with the above mentioned equity offerings, provided sufficient capital
to build and start-up the Hot Mill. The Company repaid U.S.$50 million of
principle on this facility concurrently with the closing of the Offerings.
 
    In early 1996, the Thai financial institutions providing the funding for the
construction of the Hot Mill indicated that, when needed, they would submit a
proposal to fund the construction of the DRI Facility and the Finishing
Facilities. During the first half of 1997, the Company realized that these
financial institutions might not be in a position to submit such a proposal and
began to structure a financing transaction involving U.S. based debt and equity
investors.
 
    Total capital expenditures to construct the Mill is projected to be U.S.$764
million, U.S.$487 million had been paid as of December 31, 1997.
 
    The Company's estimate of costs to complete the Mill is U.S.$277 million,
including approximately U.S.$102 million which was incurred but unpaid as of
December 31, 1997. The Company had to obtain additional financing through the
Offerings and Equity Investments in order to meet the costs of completing
construction and beginning operations of the Mill. Following the Offerings and
the completion of the Equity Investments, the Company had U.S.$288 million
available to fund completion of the Mill.
 
                                       41

    Concurrently with the Offerings, the Company entered into the Working
Capital Facility, which is secured by certain accounts receivable. The Working
Capital Facility is collateralized separately from the Notes based entirely on
funded accounts receivable and has no claim on the Collateral. The Company
believes this facility, together with its cash flows from operations, will be
sufficient to meet its working capital requirements.
 
    The Issuers consummated a private placement consisting of the Debentures and
the Private Placement Shares. The gross proceeds of the Debentures were
U.S.$43.5 million. The gross proceeds of the Private Placement Shares were 644
million Baht (U.S.$14 million). The Debentures have a cash coupon of 12.75%, a
yield to maturity of 16.36% and a maturity date of February 1, 2009. The funds
from the private placement will be used, together with a portion of the net
proceeds of the Offerings, to finance operating expenses and start-up costs
associated with the Mill. See "Description of Certain Indebtedness--Subordinated
Second Mortgage Debentures."
 
    The Company has entered into a commitment with Banque Nationale de Paris
("BNP") under which BNP, acting as the Company's agent, will pursue a
refinancing through the Export-Import Bank of the United States (the "U.S. Ex-Im
Bank") of up to U.S.$158 million of the Company's indebtedness owed to certain
Thai financial institutions. Such refinancing is subject to final credit
approval of the U.S. Ex-Im Bank, definitive documentation and certain other
conditions being met. It is anticipated that this financing would be in the form
of term loans granted by BNP and supported by the U.S. Exim Bank, with drawdowns
to be made directly to suppliers of goods and services to the Company in the
United States. The financing would require unconditional guarantees from the
Company's existing Thai lenders.
 
U.S. GAAP RECONCILIATION
 
    The Company prepares its financial statements in accordance with Thai GAAP.
For information concerning certain differences between Thai GAAP and U.S. GAAP
as applied to the Company's financial statements, see Note 22 to the Audited
Financial Statements.
 
EFFECTS OF INFLATION
 
    The Company does not expect inflation in Thailand, where substantially all
of its operations are located, to have material impact on its results of
operations.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
    In connection with the sale of the Old Securities, the Company and the Note
Issuers entered the agreements described under "Old Registration Rights"
pursuant to which the Company and the Note Issuers agreed to use their best
efforts to file with the Commission a registration statement with respect to the
exchange of the applicable Old Securities for a series of registered debt
securities with terms identical in all material respects to the terms of the
applicable Old Securities, except that the New Securities have been registered
under the Securities Act and are issued free of any covenant regarding
registration, including the payment of additional interest upon a failure to
file or have declared effective an exchange offer registration statement or to
consummate the Exchange Offer by certain dates.
 
    The Company and the Note Issuers are making the Exchange Offers in reliance
on the position of the staff of the Commission as set forth in the no-action
letter from the Commission's Division of Corporate Finance to Grupo Financiero
InverMexico, S.A., dated April 4, 1995 and the Commission's no-action letters
referenced therein addressed to other parties in other transactions. However,
the Company and the Note Issuers have not sought their own no-action letter and
there can be no assurance that the staff of the Commission would make a similar
determination with respect to the Exchange Offers as in such other
circumstances. Based upon these interpretations by the staff of the Commission,
the Company and the Note Issuers believe that New Securities issued pursuant to
these Exchange Offers in exchange for Old Securities may be offered for resale,
resold and otherwise transferred by a holder thereof other than (i) a
broker-dealer who purchased such Old Securities directly from the Company to
resell pursuant to Rule 144A or any other available exemption under the
Securities Act or (ii) a person that is an "affiliate" (as defined in Rule 405
of the Securities Act) of the Company or the Note Issuers without compliance
with the registration and prospectus deliver provisions of the Securities Act,
provided that such New Securities are acquired in the ordinary course of such
holder's business and that such holder is not participating, and has no
arrangement or understanding with any person to participate, in the distribution
of such New Securities. Holders of Old Securities accepting the Exchange Offer
will represent to the Company and the Note Issuers in the Letter of Transmittal
that such conditions have been met. Any holder who participates in the Exchange
Offer for the purpose of participating in a distribution of the New Securities
may not rely on the position of the staff of the Commission as set forth in
these no-action letters and would have to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. A secondary resale transaction in the United
States by a holder who is using the Exchange Offers to participate in the
distribution of New Securities must be covered by a registration statement
containing the selling security holder information required by Item 507 of
Regulation S-K of the Securities Act.
 
    Each broker-dealer that receives New Securities for its own account pursuant
to the Exchange Offers must acknowledge that it acquired the Old Securities as a
result of market-making activities or other trading activities and will deliver
a prospectus in connection with any resale of such New Securities. 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 New Securities received in
exchange for Old Securities where such Old Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Letter of Transmittal states that by acknowledging and
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. The Company and the
Note Issuers have agreed that for a period of 180 days after the Expiration
Date, they will make this Prospectus available to broker-dealers for use in
connection with any such resale. See "Plan of Distribution."
 
    Except as aforesaid, this Prospectus may not be used for an offer to resell,
resale or other retransfer of New Securities.
 
                                       43

    The Exchange Offers are not being made to, nor will the Company and the Note
Issuers accept tenders for exchange from, holders of Old Securities in any
jurisdiction in which the Exchange Offers or the acceptance thereof would not be
in compliance with the securities or blue sky laws of such jurisdiction.
 
TERMS OF THE EXCHANGE
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
Company and the Note Issuers will, unless such Old Securities are withdrawn in
accordance with the withdrawal rights specified in "Withdrawal of Tenders"
below, accept any and all Old Securities validly tendered prior to 5:00 p.m.,
New York City time, on the Expiration Date. The date of acceptance for exchange
of the Old Securities, and consummation of the Exchange Offer, is the Exchange
Date, which will be the first business day following the Expiration Date (unless
extended as described herein). The Company will issue, on or promptly after the
Exchange Date up to $249,000,000 aggregate principal amount of New Senior Notes
up to 203,500,000 aggregate principal amount of New Senior Subordinate Notes and
up to 53,133,016 aggregate principal amount of New Debentures tendered and
accepted in connection with the Exchange Offer. The New Notes issued in
connection with the Exchange Offer will be delivered on the earliest practicable
date following the Exchange Date. Holders may tender some or all of their Old
Securities in connection with the Exchange Offer. However, Old Securities may be
tendered only in integral multiples of US $1000 (except the Old Debentures,
which may be tendered only in integral multiples of US$1).
 
    The terms of the New Securities are identical in all material respects to
the terms of the Old Securities, except that the New Securities have been
registered under the Securities Act and are issued free from any covenant
regarding registration, including the payment of additional interest upon a
failure to file or have declared effective an exchange offer registration
statement or to consummate the Exchange Offers by certain dates. The New
Securities will evidence the same debt as the Old Securities and will be issued
under and be entitled to the same benefits under the Indenture as the Old
Securities. As of the date of this Prospectus, $249,000,000 aggregate principal
amount of the Old Senior Notes is outstanding, $203,500,000 aggregate principal
amount of Old Senior Subordinate Notes is outstanding and 153,133,016 aggregate
principal amount of Old Debentures is outstanding.
 
    In connection with the issuance of the Old Securities, the Company arranged
for the Old Securities originally purchased by qualified institutional buyers to
be issued and transferable in book-entry form through the facilities of The
Depository Trust Company ("DTC"), acting as depositary. Except as described
under "Book-Entry, Delivery and Form," the New Securities will be issued in the
form of a global note registered in the name of DTC or its nominee and each
holder's interest therein will be transferable in book-entry form through DTC.
See "Description of Note Depositary Agreement, Delivery and Form."
 
    Holders of Old Securities do not have any appraisal or dissenters' rights in
connection with the Exchange Offers. Old Securities which are not tendered for
exchange or are tendered but not accepted in connection with the Exchange Offer
will remain outstanding and be entitled to the benefits of the applicable
Indenture, but will not be entitled to any registration rights under the
applicable registration rights agreement.
 
    The Company shall be deemed to have accepted validly tendered Old Securities
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purposes of receiving the New Securities from the Company.
 
    If any tendered Old Securities are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Old Securities will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the Expiration Date.
 
    Holders who tender Old Securities in connection with the Exchange Offers
will not be required to pay brokerage commissions or fees or, subject to the
instructions in the Letter of Transmittal, transfer taxes
 
                                       44

with respect to the exchange of Old Securities in connection with the Exchange
Offer. The Company and the Note Issuers will pay all charges and expenses, other
than certain applicable taxes described below, in connection with the Exchange
Offers. See "--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on the
date that is 20 business days following the later of the date of effectiveness
of the registration statement or the date of the Exchange Offer is otherwise
commenced unless extended by the Company and the Note Issuers in their sole
discretion (but in no event to a date later than       , 1998), in which case
the term "Expiration
Date" shall mean the latest date and time to which the Exchange Offer is
extended.
 
    The Company and the Note Issuers reserve the right, in their sole discretion
(i) to delay accepting any Old Securities, to extend the Exchange Offer or to
terminate the Exchange Offer and to refuse to accept Old Securities not
previously accepted, if any of the conditions set forth below under "Conditions
to the Exchange Offer" shall not have been satisfied and shall not have been
waived by the Company and the Note Issuers (if permitted to be waived by the
Company and the Note Issuers) and (ii) to amend the terms of the Exchange Offer
in any manner. Any such delay in acceptance, extension, termination or amendment
will be followed as promptly as practicable by oral or written notice thereof to
the registered holders. If the Exchange Offers are amended in a manner
determined by the Company and the Note Issuers to constitute a material change,
the Company and the Note Issuers will promptly disclose such amendment by means
of a prospectus supplement that will be distributed to the registered holders of
the Old Securities, and the Company and the Note Issuers will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such five to ten
business day period. In no event, however, shall the Exchange Date be later than
the first business day following       , 1998.
 
    If the Company and the Note Issuers determine to make a public announcement
of any delay, extension, amendment or termination of the Exchange Offer, the
Company and the Note Issuers shall have no obligation to publish, advertise or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
INTEREST ON THE NEW SECURITIES
 
    The New Securities will bear interest at the same rate as the applicable Old
Security. Interest on the New Securities shall accrue from the last Interest
Payment Date on which interest was paid on the Old Securities surrendered or, in
no interest has been paid on the Old Securities, from March 12, 1998. Interest
on the New Securities will be payable semiannually on February 1 and August 1 of
each year, commencing August 1, 1998.
 
    Holders of Old Securities whose Old Securities are accepted for exchange
will not receive interest on such Old Securities for any period subsequent to
the last interest payment date to occur prior to the issue date of the New
Securities, and will be deemed to have waived the right to receive any interest
payment on the Old Securities accrued from and after such interest payment date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offers, the Company and the
Note Issuers will not be required to accept for exchange, or to exchange, any
Old Securities for any New Securities, and may terminate or amend the Exchange
Offers before the acceptance of any Old Securities for exchange, if:
 
        (a) any action or proceeding is instituted or threatened in any court or
    by or before any governmental agency with respect to the Exchange Offers
    which, in the Company's or Note Issuer's reasonable good faith judgment,
    would be expected to impair the ability of the Company and the Note Issuers
    to proceed with the Exchange Offers, or
 
                                       45

        (b) any law, statute, rule or regulation is adopted or enacted, or any
    existing law, statue, rule or regulation is interpreted by the Commission or
    its staff, which, in the Company's or the Note Issuers' reasonable good
    faith judgment, would be expected to impair the ability of the Company and
    the Note Issuers to proceed with the Exchange Offers.
 
    If the Company and the Note Issuers determine in their reasonable good faith
judgment that any of the foregoing conditions exist, the Company and the Note
Issuers may (i) refuse to accept any Old Securities and return all tendered Old
Securities to the tendering holder, (ii) extend the Exchange Offers and retain
all Old Securities tendered prior to the expiration of the Exchange Offers,
subject, however, to the rights of holders who tendered such Old Securities to
withdraw their tendered Old Securities which have not been withdrawn. If such
waiver constitutes a material change to the Exchange Offers, the Company and the
Note Issuers will promptly disclose such waiver by means of a prospectus
supplement that will be distributed to the registered holders, and the Company
and the Note Issuers will extend the Exchange Offers for a period of five to ten
business days, depending upon the significance of the waiver and the manner of
disclosure to the registered holders, if the Exchange Offers would otherwise
expire during such five to ten business days. In no event, however, shall the
Exchange Date be a date later than the first business day following       ,
1998.
 
PROCEDURES FOR TENDERING
 
    Only a holder of record of Old Securities on       , 1998 may tender such
Old Securities in connection with the Exchange Offers. To tender in connection
with the Exchange Offers, a holder must complete, sign and date the Letter of
Transmittal, or a facsimile thereof, have the signatures thereon guaranteed if
required by the Letter of Transmittal and mail or otherwise deliver such Letter
of Transmittal or such facsimile, together with the Old Securities (unless such
tender is being effected pursuant to the procedure for book-entry transfer
described below) and any other required documents, to the Exchange Agent prior
to 5:00 p.m., New York City time, on the Expiration Date.
 
    Any financial institution that is a participant in DTC's Book-Entry Transfer
Facility system may make book-entry delivery of the Old Securities by causing
DTC to transfer such Old Securities into the Exchange Agent's account in
accordance with DTC's procedure for such transfer. Although delivery of Old
Securities may be effected through book-entry transfer into the Exchange Agent's
Account at DTC, the Letter of Transmittal (or facsimile thereof), with any
required signature guarantees and any other required documents, must, in any
case, be transmitted to and received or confirmed by the Exchange Agent at its
addresses set forth under the caption "Exchange Agent," below, prior to 5:00
p.m., New York City time, on the Expiration Date. DELIVERY OF DOCUMENTS TO DTC
IN ACCORDANCE WITH ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE
AGENT.
 
    The tender by a holder of Old Securities will constitute an agreement
between such holder and the Company and the Note Issuers in accordance with the
terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
    The method of delivery of Old Securities and the Letter of Transmittal and
all other required documents to the Exchange Agent is at the election and risk
of the holders. Instead of delivery by mail, it is recommended that holders 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. No
Letter of Transmittal or Old Securities should be sent to the Company or the
Note Issuers. Holders may request their respective brokers, dealers, commercial
banks, trust companies or nominees to effect the tenders for such holders.
 
    Any beneficial owner whose Old Securities are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. If such
beneficial owner wishes to tender on such owner's own behalf, such owner must,
prior to completing and executing
 
                                       46

the Letter of Transmittal and delivery of such owner's Old Securities, either
make appropriate arrangements to register ownership of the Old Securities in
such owner's name or obtain a properly completed bond power from the registered
holder. The transfer of registered ownership may take considerable time.
 
    Signature on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined below) unless
the Old Securities tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box entitled "Special Payment Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal, or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter of
Transmittal or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guarantee must be by a member firm
of a registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor institution" within
the meaning of Rule 17 Ad-15 under the Exchange Act (an "Eligible Institution").
 
    If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Securities listed therein, such Old Securities must be
endorsed by such registered holder or accompanied by a properly completed bond
power, in such case signed or endorsed in blank by such registered holder as
such registered holder's name appears on such Old Securities.
 
    If the Letter of Transmittal or any Old Securities or bond powers are signed
or endorsed by trustees, executors, administrators, guardians, attorney-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company and the Note Issuers, evidence satisfactory to the Company and the Note
Issuers of their authority to so act must be submitted with the Letter of
Transmittal.
 
    All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Securities will be
determined by the Company and the Note Issuers in their sole discretion, which
determination will be final and binding. The Company and the Note Issuers
reserve the absolute right to reject any and all Old Securities not properly
tendered or any Old Securities whose acceptance by the Company and the Note
Issuers would, in the opinion of U.S. counsel to the Company and Note Issuers,
be unlawful. The Company and the Note Issuers also reserve the right to waive
any defects, irregularities or conditions of tender as to any particular Old
Securities either before or after the Expiration Date. The Company's and the
Note Issuers' interpretation of the terms and conditions of the Exchange Offers
(including the Instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Old Securities must be cured within such time as the
Company and the Note Issuers shall determine. Although the Company and the Note
Issuers intend to request the Exchange Agent to notify holders of defects or
irregularities with respect to tenders of Old Securities, neither the Company,
the Note Issuers, the Exchange Agent nor any other person shall have any duty or
incur any liability for failure to give such notification. Tenders of Old
Securities will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Securities received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
    In addition, the Company and the Note Issuers reserve the right, as set
forth above under the caption "Conditions to the Exchange Offers," to terminate
the Exchange Offers.
 
    By tendering, each holder represents to the Company and the Note Issuers
that, among other things, the New Securities acquired in connection with the
Exchange Offers are being obtained in the ordinary course of business of the
person receiving such New Securities, whether or not such person is the holder,
that neither the holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Securities and that neither the holder nor any such other person is an
"affiliate" (as defined in Rule 405 under the Securities Act) of the Company or
the Note Issuers. If
 
                                       47

the holder is a broker-dealer which will receive New Securities for its own
account in exchange of Old Securities, it will acknowledge that it acquired such
Old Securities as the result of market making activities or other trading
activities and it will deliver a prospectus in connection with any resale of
such New Securities.
 
GUARANTEED DELIVERY PROCEDURES
 
    Holders who wish to tender their Old Securities and (i) whose Old Securities
are not immediately available, or (ii) who cannot deliver their Old Securities,
the Letter of Transmittal or any other required documents to the Exchange Agent,
or cannot complete the procedure for book-entry transfer, prior to the
Expiration Date, may effect a tender of their Old Securities if:
 
        (a) The tender is made through an Eligible Institution;
 
        (b) Prior to the Expiration Date, the Exchange Agent received from such
    Eligible Institution a properly completed and duly executed Notice of
    Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
    setting forth the name and address of the holder, the certificate number(s)
    of such Old Securities and the principal amount of Old Securities tendered,
    stating that the tender is being made thereby and guaranteeing that, within
    five business days after the Expiration Date, the Letter of Transmittal (or
    facsimile thereof) together with the certificate(s) representing the Old
    Securities to be tendered in proper form for transfer (or confirmation of a
    book-entry transfer into the Exchange Agent's account at DTC of Old
    Securities delivered electronically) and any other documents required by the
    Letter of Transmittal will be deposited by the Eligible Institution with the
    Exchange Agent; and
 
        (c) Such properly completed and executed Letter of Transmittal (or
    facsimile thereof) as well as the certificate(s) representing all tendered
    Old Securities in proper form for transfer (or confirmation of a book-entry
    transfer into the Exchange Agent's account at DTC of Old Securities
    delivered electronically) and all other documents required by the Letter of
    Transmittal are received by the Exchange Agent within five business days
    after the Expiration Date.
 
WITHDRAWAL OF TENDERS
 
    Except as otherwise provided herein, tenders of Old Securities may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
    To withdraw a tender of Old Securities in connection with the Exchange
Offer, a written facsimile transmission notice of withdrawal must be received by
the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York
City time, on the Expiration Date. Any such notice of withdrawal must (i)
specify the name of the person who deposited the Old Securities to be withdrawn
(the "Depositor"), (ii) identify the Old Securities to be withdrawn (including
the certificate number or numbers and principal amount of such Old Securities),
(iii) be signed by the Depositor in the same manner as the original signature on
the Letter of Transmittal by which such Old Securities were tendered (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the trustee register the transfer of such Old Securities into
the name of the person withdrawing the tender, and (iv) specify the name in
which any such Old Securities are to be registered, if different from that of
the Depositor. All questions as to the validity, form and eligibility (including
time of receipt) of such withdrawal notices will be determined by the Company
and the Note Issuers, whose determination shall be final and binding on all
parties. Any Old Securities so withdrawn will be deemed not to have been validly
tendered for purposes of the Exchange Offer and no New Securities will be issued
with respect thereto unless Old Securities so withdrawn are validly retendered.
Any Old Securities which have been tendered but which are not accepted for
exchange or which are withdrawn will be returned to the holder thereof without
cost to such holder as soon as practicable after withdrawal, rejection of tender
or termination of the Exchange Offer. Properly withdrawn Old Securities may be
retendered by following one of the procedures described above under the caption
"Procedures for Tendering" at any time prior to the Expiration Date.
 
                                       48

EXCHANGE AGENT
 
          has been appointed as Exchange Agent in connection with the Exchange
Offer. Questions and requests for assistance, requests for additional copies of
this Prospectus or of the Letter of Transmittal should be directed to the
Exchange Agent, at its offices at       , New York, New York       . The
Exchange Agent's telephone number is (212)    -    and facsimile number is (212)
   -    .
 
FEES AND EXPENSES
 
    The Company and the Note Issuers will not make any payment to brokers,
dealers or others soliciting acceptances of the Exchange Offer. The Company and
the Note Issuers will pay certain other expenses to be incurred in connection
with the Exchange Offer, including the fees and expenses of the Trustee,
accounting and certain legal fees.
 
    Holders who tendered their Old Securities for exchange will not be obligated
to pay any transfer taxes in connection therewith. If, however, New Securities
are to be delivered to, or are to be issued in the name of, any person other
than the registered holder of Old Securities tendered, or if tendered Old
Securities are registered in the name of any person other than the person
signing the Letter of Transmittal, or if a transfer tax is imposed for any
reason other than the exchange of Old Securities in connection with the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendered holder.
 
ACCOUNTING TREATMENT
 
    The New Securities will be recorded at the same carrying value as the Old
Securities as reflected in the Company's and the Note Issuers' accounting
records on the date of the exchange. Accordingly, no gain or loss for accounting
purposes will be recognized by the Company or the Note Issuers upon the
consummation of the Exchange Offer. Any expenses of the Exchange Offer that are
paid by the Company or the Note Issuers will be amortized by the Company or the
Note Issuers, as the case may be, over the term of the New Securities in
accordance with generally accepted accounting principles.
 
CONSEQUENCES OF FAILURES TO PROPERLY TENDER OLD NOTES IN THE EXCHANGE
 
    Issuance of the New Securities in exchange for the Old Securities pursuant
to the Exchange Offers will be made only after timely receipt by the Exchange
Agent of such Old Securities, a properly completed and duly executed Letter of
Transmittal and all other required documents. Therefore, holders of the Old
Securities desiring to tender such Old Securities in exchange for New Securities
should allow sufficient time to ensure timely delivery. The Company and the Note
Issuers are under no duty to give notification of defects or irregularities with
respect to tenders of Old Securities for exchange. Old Securities that are not
tendered or that are tendered but not accepted by the Company and the Note
Issuers for exchange, will, following consummation of the Exchange Offer,
continue to be subject to the existing restrictions upon transfer thereof under
the Securities Act and, upon consummation of the Exchange Offer, certain
registration rights under the applicable registration rights agreement will
terminate.
 
    In the event the Exchange Offers is consummated, the Company and the Note
Issuers will not be required to register the remaining Old Securities. Remaining
Old Securities will continue to be subject to the following restrictions on
transfer: (i) the remaining Old Securities may be resold only if registered
pursuant to the Securities Act, if any exemption from registration is available
thereunder, or if neither such registration nor such exemption is required by
law, and (ii) the remaining Old Securities will bear a legend restricting
transfer in the absence of registration or an exemption therefrom. The Company
and the Note Issuers do not currently anticipate that they will register the
remaining Old Securities under the Securities Act. To the extent that Old
Securities are tendered and accepted in connection with the Exchange Offers, any
trading market for remaining Old Securities could be adversely affected.

services from SDI, a leading mini-mill operator in the United States, under the
SDI Agreement. Concurrently with the Offerings and in connection with the SDI
License Agreement which included the grant by SDI and NSM of reciprocal license
rights to certain technical and operational know-how, SDI received 74,468,090
Ordinary Shares. NSM also issued the SDI Warrants to SDI to purchase up to
11,421,480 Ordinary Shares, which contain exercise provisions that protect SDI
from dilution of its equity interest in the event holders of Warrants exercise
such Warrants. In addition to SDI, Enron and McDonald acquired newly issued
Ordinary Shares on the Issue Date. Enron and McDonald, among others, also
purchased an aggregate of 45 million Ordinary Shares in a privately negotiated
transaction in the secondary market for the Company's shares. Enron additionally
acquired a significant portion of the 64,417,180 Ordinary Shares privately
placed by the Company concurrently with the Debenture Offering. Giving effect to
the Transactions and the other purchases described below, the Management
Investors in the aggregate hold a 20.56% interest in the Company's issued and
outstanding Ordinary Shares.
 
    Construction and start-up of the Hot Mill, the core of the mini-mill has
been completed. The Hot Mill rolled its first coil of steel during operational
testing in October 1997 and melted, cast, and hot-rolled its first coil of steel
in December 1997. The Company began commercial operations in the first quarter
of 1998. The Company's goal is to be the world's most efficient and lowest cost
producer of high-quality flat-rolled steel products, including hot-rolled,
cold-rolled and galvanized steel, as well as other specialty steel products. The
recent devaluation of the Baht has reduced certain of the Company's current
capital expenditure obligations and may lower certain of its operating costs.
 
    Upon completion, NSM's mini-mill will consist of three facilities: (i) the
Hot Mill for steel melting, refining, casting and hot-rolling, (ii) the DRI
Facility, for the production of DRI, which includes the Co-Gen Facility being
developed in conjunction with Enron, and (iii) the Finishing Facilities. The
Company believes that the Mill's design utilizes a unique combination of the
best commercially proven technologies currently in use in some of the most
efficient and highest quality steel manufacturing facilities in the world.
 
    The Hot Mill has a designed annual production capacity of 1.5 million
tonnes. The Hot Mill utilizes advanced technology steel melting and refining,
CSP casting and hot-rolling processes and equipment. The Finishing Facilities,
which are expected to be operational in the first quarter of 1999, will
incorporate a multi-purpose high-capacity production line and several lower
capacity production units with a combined rated annual production capacity of
1.5 million tonnes. The DRI Facility, which is expected to be operational during
the second quarter of 1999, will have an annual rated production capacity of
500,000 tonnes and will provide the Company with a low-cost substitute for
approximately 30% of the scrap in its melt mix. The Company believes that this
equipment will allow it to produce thinner gauge, higher value steel in
hot-rolled form with consistently better tolerances, uniformity and surface
qualities relative to other flat-rolled steel producers. NSM believes that the
resulting increased product breadth and cost advantages produced by combining
the DRI Facility, Hot Mill and Finishing Facilities together in a continuous
process will allow it to become a world class flat-rolled steel producer based
on cost, quality and timeliness of delivery.
 
    The world's flat-rolled steel market is dominated by integrated steel
producers using conventional blast furnaces and eight-to-ten-inch slab
production methods. The Company believes that thin-slab/flat-rolled steel
mini-mills can compete favorably against integrated steel producers in terms of
cost, quality and timeliness of delivery, while producing superior financial
results. Thailand is one of the largest
 
                                       50

importers of flat-rolled steel in the world, ranking third in 1996 in terms of
net steel imported. Virtually all of the steel products imported into Thailand
are produced by high-cost integrated steel producers with lengthy delivery
schedules.
 
    The demand for flat-rolled products in Thailand results, in part, from the
development over the past 20 years of several industries including the
manufacturing of pipe and tube, containers, furniture, appliances, automotive
parts and vehicles. NSM is the only flat-rolled steel producer in Thailand.
Accordingly, the Company believes that it is well positioned to capture a
significant share of the demand for flat-rolled steel in Thailand by producing a
broad range of high-quality products.
 
    In order to ensure consistent and efficient mill utilization and to mitigate
NSM's exposure to the economic difficulties currently being experienced in
Thailand, the Company has entered into eight-year off-take agreements with
Preussag and Klockner. Preussag and Klockner are two international steel trading
and processing companies which sell high-quality, high-grade steel products
throughout the world. Under the Off-Take Agreements Preussag and Klockner will
be obligated to purchase, in aggregate, 100% of the Company's production in 1998
through 2002, and 25% of the Company's production in the years 2001 through
2005. NSM may, at is option, reduce the percentage of its production sold under
the Off-Take Agreements to as little as 67% in 1998, 50% in 1999 and 25% in
2000, if the Company believes it could maximize sales revenue through sales to
other customers. Under the Indentures, sales by NSM to customers other than
Preussag and Klockner, to the extent that the aggregate of such sales results in
receivables outstanding in excess of U.S. $10 million, must be supported by
letters of credit if the customer does not have an investment grade credit
rating. All sales to Preussag and Klockner and substantially all other export
sales will be U.S.$ denominated.
 
    In addition to the Off-Take Agreements, the Company has entered into a
commercial assistance agreement with the former chief commercial officer of U.S.
Steel to facilitate the Company's introduction to flat-rolled steel customers.
Based on international customer inquiries received by the Company to date, the
Company believes that it could increase the percentage of its annual production
sold under off-take agreements in 2001 through 2005 should economic conditions
in the Asia-Pacific region warrant. The Company also believes, that as a
low-cost producer of high-quality steel products, it will have the option to
sell its products in either domestic or world markets, including the United
States.
 
    NSM has entered into various agreements to ensure its access to and
availability of electric power, natural gas, oxygen, coal and iron ore. NSM has
entered into arrangements under which PEA and PTT will provide NSM with electric
power and natural gas. PEA and PTT are government entities charged with
providing electricity and natural gas, respectively, to Thailand's industrial
base. NSM will benefit from two new power substations adjacent to the Mill
constructed by EGAT and from two sets of new power lines which run to the Mill
site, all recently constructed by PEA. NSM also has access to a long-term supply
of oxygen and other industrial gases from Bangkok Industrial Gas, which has
recently constructed an oxygen plant adjacent to the Mill. Coal and iron ore,
two important raw materials needed to produce DRI, are being supplied under
long-term contracts by SSM and MMTC.
 
    When complete, the Company estimates that its total investment in the Mill
for property, plant, land, buildings, machinery and equipment will to be
approximately U.S.$764 million. The Company's investment in the land, buildings,
machinery and equipment of the Mill as of December 31, 1997 was approximately
U.S.$588 million, including approximately U.S.$514 million in connection with
the construction of the Hot Mill, approximately U.S.$32 million in connection
with the DRI Facility and approximately U.S.$42 million in connection with the
Finishing Facilities.
 
    During 1998, while the DRI Facility and Finishing Facilities are expected to
be under construction, interest on the Notes will be paid from amounts on
deposit in the Notes DSR Account. As of December 31, 1997, after giving pro
forma effect to the Transactions, the Company would have had total shareholders'
equity of U.S.$158 million and total indebtedness of U.S.$771 million, of which
U.S.$336 million would have been secured equally and ratably with the Guaranties
(other than the Debenture Guaranty).
 
                                       51

PROJECT ADVANTAGES
 
    NSM believes that it enjoys a number of advantages over other flat-rolled
steel producers and that these advantages will facilitate the implementation of
its business strategy. Through the use of advanced technology throughout the
Mill, the Company believes that its projected cost structure will place it among
the lowest cost producers of flat-rolled steel products in the world.
Complementing the Company's projected low cost structure is its designed
capability to produce a full range of flat-rolled products, including high
value-added products that previously could only be produced by higher cost
integrated steel producers. The Company believes that this ability to produce
high value-added products coupled with its projected low cost structure, will
enable it to compete effectively in selling its products, to the domestic and
world steel markets. Further complementing the Company's projected cost
structure and product capabilities will be its right to obtain certain technical
and operational advice and consultation services from SDI, as well as access to
the strategic expertise of Enron and McDonald.
 
BUSINESS STRATEGY
 
    NSM's business strategy is to use its advanced Hot Mill, DRI Facility and
Finishing Facilities technologies to produce superior quality flat-rolled steel
in a variety of high value-added forms. The principal elements of the Company's
strategy include:
 
    - ACHIEVE CONVERSION COSTS AMONG THE LOWEST IN THE STEEL INDUSTRY. The
      Company believes that the design of the Mill represents substantial
      efficiency improvements over earlier mini-mills using CSP technology.
      These improvements are expected to substantially reduce the cost and
      production time of the steel-making process, limit electric arc furnace
      ("EAF") power-off and downtime, reduce consumption of consumable inputs
      and ultimately produce higher quality steel. By designing and utilizing
      equipment that is efficient, consumes fewer raw materials and improves the
      consistency and reliability of the steelmaking process, the Company
      believes that its per tonne manufacturing costs will be among the lowest
      in the steel industry.
 
    - EMPHASIZE VALUE-ADDED PRODUCTS. NSM believes that it will be able to
      produce thinner gauge steel in hot-rolled form with consistently better
      uniformity, tolerances and surface quality relative to other flat-rolled
      steel producers. The Company also believes that its high-quality, thinner
      gauge hot-rolled products will compete favorably with certain more
      expensive cold-rolled (further processed) products, enabling it to achieve
      higher margins. Thinner gauge, hot-rolled products, and other value-added
      products, may be less susceptible to the price fluctuations commonly found
      in the spot market for commodity grade steel. The design of the Finishing
      Facilities' process lines is expected to result in higher quality
      products, significant cost savings and yield improvements relative to the
      processing systems used by most other flat-rolled steel producers. In
      addition, the Company expects to devote a substantial portion of its
      hot-rolled capacity to the production of higher margin pickled and oiled,
      cold-rolled, galvanized, and other value added steel products. The Company
      believes that the resulting increased product breadth and cost advantages
      will allow it to compete favorably on a cost and quality basis with any
      steel producer in the world.
 
    - SECURE A SOLID BASELOAD OF U.S.$ SALES. In order to ensure consistent and
      efficient Mill utilization and to balance U.S.$ revenues with U.S.$ debt
      service and expense requirements, the Company has entered into the
      Off-Take Agreements. Under the Off-Take Agreements, Preussag and Klockner
      will be obligated to purchase, in aggregate, 100% of the Company's
      production in 1998 through 2002, and 25% of the Company's production in
      the years 2001 through 2005. NSM may, at is option, reduce the percentage
      of its production sold under the Off-Take Agreements to as little as 67%
      in 1998, 50% in 1999 and 25% in 2000, if the Company believes it could
      maximize sales revenue through sales to other customers. Under the
      Indentures, sales by NSM to customers other that Preussag and Klockner, to
      the extent that the aggregate of such sales results in receivables
      outstanding in excess of U.S.$10 million, must be supported by letters of
      credit if the customer does
 
                                       52

      not have an investment grade credit rating. All sales to Preussag,
      Klockner and substantially all other export sales will be U.S.$
      denominated. Based on international customer inquiries, the Company
      believes that it could substantially increase the percentage of its annual
      production sold under off-take agreements in 2001 through 2005 should
      economic conditions in the Asia-Pacific region warrant. The Company
      believes that as a low-cost producer of high-quality steel products, it
      will have the option to sell all of its products in either domestic or
      world markets, including the United States.
 
    - MAXIMIZE MINI-MILL ADVANTAGES. The Company has adopted a combination of
      technologies and management techniques which management believes will
      provide it with the flexibility to deliver custom ordered, just-in-time,
      high-quality products to customers with minimal lead times. NSM has
      adopted management and personnel policies designed to take advantage of
      the opportunities inherent in the technological revolution in the
      flat-rolled steel industry. The Company expects its energy consumption,
      man-hours per tonne produced and the environmental impact of the
      operations to be among the lowest in the industry. The Company intends to
      use its advanced technologies to develop profitable niche market products.
 
    - UTILIZE LEADING MINI-MILL OPERATIONAL AND MANAGEMENT TECHNIQUES. The
      Company has entered into agreements with a number of leading steel
      mini-mill developers and operators in order to make available to
      Management Co. or the Company certain technical knowhow and business
      practices. Under the terms of the SDI Agreement, SDI, a company whose
      executives and managers pioneered the development of thin-slab/flat-rolled
      technology and directed the construction and operation of the world's
      first thin-slab/flat-rolled minimill, will provide management advisory and
      periodic on-site technical support to Management Co. Hylsa, under the
      Hylsa Agreement, has provided training to over 140 NSM employees at its
      Monterey, Mexico plant, and will continue to provide training and on-site
      technical support. Hylsa is recognized in the world steel making community
      for producing high-quality, thin-gauge products utilizing CSP technology.
      From early 1996 through mid-1997, the Company received certain technical
      assistance and employee training for over 170 NSM employees from Nucor,
      currently an operator of eight mini-mills in the United States.
 
    - SECURE RAW MATERIAL SOURCES. The primary raw materials and utilities used
      to produce DRI and flat-rolled steel products are coal, iron ore,
      electricity and scrap. To secure access to adequate low-cost supplies of
      these inputs, NSM has entered into long-term agreements for the supply of
      coal, iron ore and electricity with SSM, MMTC, and PEA, respectively. For
      scrap, NSM will have access to both the domestic and global scrap markets.
      Management believes that due to the recent Baht devaluation and the
      logistical and regulatory obstacles to exporting scrap from Thailand,
      NSM's near term domestic scrap costs will be U.S.$20-30 per tonne lower
      than world market prices.
 
    - EXPLOIT STRATEGIC LOCATION. The Company is the only flat-rolled steel
      producer in Thailand, historically one of the world's largest importers of
      finished and semi-finished flat-rolled steel. In 1996, Thailand ranked
      sixth in the world in terms of imported steel. The Company believes that
      demand in Thailand for steel products will remain strong due in part to
      direct foreign investment by steel consuming entities in Thailand. The
      Company believes that strong domestic demand combined with import tariffs
      on certain steel products would allow the Company to achieve higher profit
      margins on the sale of its products in Thailand relative to sales outside
      of Thailand.
 
    - UTILIZE THE EXPERTISE OF SDI, ENRON AND MCDONALD. NSM and Management Co.
      have contracted to acquire certain strategic and financial expertise that
      will enhance NSM's ability to compete both financially and operationally
      in the world steel market. By becoming equity owners of NSM and through
      their representation on the Company's board of directors, the Company
      expects that SDI's, Enron's and McDonald's representatives on the board of
      directors will provide the Company with certain know how, expertise and
      knowledge.
 
                                       53

    - PURSUE EXPANSION OPPORTUNITIES. In order to lower production costs through
      economies of scale, the Company intends to pursue expansion of the Mill if
      market conditions warrant such an expansion. To facilitate expansion of
      DRI production capacity, NSM designed the DRI Facility to accommodate a
      tripling of capacity. In addition to mitigating NSM's reliance on the
      global scrap market, an expanded DRI Facility would produce a significant
      amount of additional electric power at economically attractive rates for
      use in the Hot Mill. NSM also designed the Hot Mill and Finishing
      Facilities to facilitate expansion. In aggregate, the cost of increasing
      the capacity of the DRI Facility by 1.0 million tonnes per year, the Hot
      Mill by 1.2 million tonnes per year and the Finishing Facilities by
      100,000 tonnes per year is estimated by the Company to approximate
      U.S.$250 million.
 
INDUSTRY OVERVIEW
 
    The world steel industry has historically been and continues to be highly
cyclical, influenced by many factors, including periods of economic growth and
recession, strength and weakness of various currencies, worldwide production
capacity, levels of steel imports and tariffs. The industry as a whole has also
been affected by factors impacting on specific companies, such as failure to
adapt to technological change, plant inefficiency, high inventory and labor
costs. Some lower grades of steel continue to be commodities that respond to
forces of supply and demand, and prices for these grades have been volatile and
have fluctuated in reaction to general and industry specific economic
conditions. However, new technologies, planning and manufacturing practices and
metallurgical know how now allow steel producers to deliver made-to-order
products which are less susceptible to commodity pricing and do not require
large finished good inventories. The Mill is designed to take advantage of such
new technologies, planning, manufacturing practices and metallurgical know how
and, accordingly, the Company believes that it may be less sensitive to business
cycles.
 
                                       54

INTEGRATED V. MINI-MILL STEEL PRODUCTION
 
    There are generally two kinds of primary steel producers, "integrated" and
"mini-mill." The following diagram illustrates the differences in production
methodologies between the typical multi-step integrated mill production process
and the typical continuous mini-mill melting-casting-rolling process.
 
                                 [LOGO]
 
    Steel manufacturing by an integrated producer involves a series of time
consuming and distinct processes, frequently separated by plant geography. This
process generally involves the following chronological steps: ironmaking,
steelmaking, billet or slab making, reheating, multi-step rolling and
flat-rolling. These processes may, in turn, be followed by various finishing
processes, including cold-rolling, annealing, and various coating processes,
including galvanizing. In integrated producer steelmaking, coal is converted to
coke in a coke oven, combined in a blast furnace with iron ore or pellets and
limestone to produce pig iron, and then combined with scrap in a "basic oxygen"
or other furnace to produce liquid raw steel. Once produced, the liquid raw
steel is metallurgically refined in the ladle metallurgy station and then either
poured into ingots for later reheating and processing or transported to a caster
for casting into a billet or slab, which is then further shaped or rolled into
its final form. Typically, whether by design or as a result of downsizing,
re-configuration or changes in technology, many integrated producers perform
these processes in separate and remote facilities resulting in more costly and
less efficient production than mini-mill producers.
 
                                       55

    In contrast, a mini-mill employs an EAF to directly melt steel scrap or
steel scrap substitutes, including DRI, thus entirely eliminating the blast
furnace, coke ovens and reducing other energy- and capital-intensive and
environmentally harmful processes. A mini-mill incorporates the melt shop, ladle
metallurgical, casting and rolling processes into a unified continuous flow. In
typical mini-mills, the melting process begins with the charging of an EAF with
scrap, carbon and lime, after which the EAF's roof is closed and electrodes are
lowered into the scrap through holes in the top of the EAF. Electricity is then
applied to the electrodes and augmented with oxygen to melt the scrap and
produce liquid raw steel.
 
    The liquid raw steel is then checked for chemistry and the necessary
metallurgical adjustments are made while the steel is still in the EAF or, if
the plant has a separate staging area for that process, the material is
transported by ladle to an area commonly known as a ladle metallurgy station.
From there, the liquid raw steel is transported by ladle to a turret at the
continuous caster, where it is transferred into a reservoir called a tundish.
The tundish controls the flow of the liquid steel into a water-cooled
copper-lined mold from which it is usually sent through a tunnel furnace
directly into the rolling process. Similar to NSM, several other operating
mini-mills have provided for further continuous operation by adding finishing
facilities directly into the production process.
 
    Mini-mills are generally characterized by lower costs of production and
higher productivity than integrated steelmakers. This is due, in part, to the
mini-mill's lower capital costs and operating costs resulting from streamlined
production processes and smaller, more efficient layouts which serves to reduce
or eliminate costly re-handling and re-heating of partially finished product.
Mini-mills are also credited with translating technological advances into
competitive advantages by decreasing costs of production and increasing product
quality.
 
    Mini-mills have been producing steel since the early 1960s, when EAFs and
continuous casting were initially commercialized and technological developments
in the steel industry generated a large surplus of scrap. Historically, due to
the mini-mill's initial quality limitations and early power and capacity
limitations, the mini-mills focused almost exclusively on lower-quality,
lower-priced "long products," including merchant shapes such as rebar, wire,
rod, angles and structural. In 1989, an innovative mini-mill operator began
producing flat-rolled steel products and commercialized the world's first CSP
thin-slab flat-rolled mini-mill. The CSP technology employed was provided by SMS
Schloemann-Siemag AG of Germany ("SMS"), the same provider of NSM's, SDI's and
Hylsa's technology. By employing a mold design that casts a 50 mm slab, which is
only 20% of the thickness of the typical 250 mm slabs cast by most integrated
producers, and by using a raw material mix with a cost structure that is lower
and more flexible, mini-mill operators have enjoyed significantly lower costs
relative to integrated steel producers. Although initially limited to
commodity-grade flat-rolled steel products, the CSP technology was subsequently
refined so that today mini-mill operators can produce a wide variety of
high-quality, flat-rolled steel products. NSM's design further advances the
capabilities of the CSP technology such that it believes it will be able to
produce a full spectrum of high-quality steel products, including those
requiring the most demanding applications and new grades that are not presently
commercially available.
 
    The CSP technology is one of the most significant advances in steel
production in the last 40 years. The ability to produce flat-rolled steel from a
thinner slab greatly reduces costs, as less reduction is necessary in the
rolling mill and there is substantially less reheating required prior to
rolling. Most importantly, the development of thin-slab casting technology, with
its lower capital investment requirement, allowed for the entry of the
mini-mills into the flat-rolled segment of the steel market. The technology has
proved to be extremely flexible and cost effective and is continuously being
further refined. NSM has incorporated this technology in an all-encompassing
metallurgical and product concept which takes full advantage of the inherent
synergies with upstream and downstream technology developments, quality
enhancements and product opportunities.
 
                                       56

NSM V. TRADITIONAL MINI-MILLS
 
    Unlike most other mini-mills, NSM designed the Mill to fully incorporate the
advantages inherent in operating a captive DRI Facility. In addition to
mitigating NSM's exposure to the global scrap market, operating the DRI Facility
facilitates its ability to produce the broadest range of flat-rolled steel
products. The consumption of DRI in its melt mix, combined with its
sophisticated ladle metallurgy, will enable NSM to produce ultra clean steel
with significantly lower residual levels and better control of all elements than
steel produced by mini-mills that are 100% scrap and pig iron dependent. The Hot
Mill and Finishing Facilities, which have been designed to produce the highest
quality grades of steel, are expected to enable NSM to compete successfully, in
terms of quality, with not only other mini-mills but integrated steel producers
as well.
 
    Further differentiating NSM from most other flat-rolled mini-mills is the
fact that it has incorporated the ConSteel continuous charging process (the
"ConSteel Process") developed by Intersteel Technology, Inc. into its Hot Mill.
The ConSteel Process eliminates the time and energy losses incurred by other
mini-mills by swinging the roof of the furnace to top charge their meltmix.
Under the Company's Hot Mill design, scrap, which has been preheated by
off-gases from the EAF, will be continuously fed into the molten raw liquid
steel heel in the EAF. The heel is a pool of molten raw liquid steel kept in the
bottom of the EAF which is continuously fed into the mold. The heel, is also
being fed hot DRI on a continuous basis through a gravity controlled feed
system. Thus, NSM will maintain a continuous power-on state and a large heel of
high-quality liquid raw steel. The Company believes that this continuous
operation will drive its steelmaking costs below those typically incurred by
traditional mini-mills. Additionally, NSM's mill has an enhanced
vacuum/oxygen/degasser ("VOD") and a short-coupled coiler. These enhancement
will facilitate NSM's production of ultra-low carbon and other high-quality
steel grades, including thin-gauge, flat-rolled steel products. The initial
production results have already demonstrated the quality benefits of the
advanced meltshop design, resulting in liquid steel quality with nitrogen,
carbon and sulfur levels which are considerably lower than in conventional
mini-mill melt shops.
 
DESCRIPTION OF FLAT-ROLLED STEEL PRODUCTS
 
    The Company designed the Mill to produce a wide variety of steel products,
including hot-rolled, cold-rolled and ultimately coated products. Each of these
products is described below.
 
    HOT-ROLLED PRODUCTS.  All coiled flat-rolled steel is initially hot-rolled,
a process that consists of passing cast steel either directly, as in the case of
NSM, or in reheated slab form through a multi-stand rolling mill to reduce its
thickness to less than 13 mm and, in some mills, including Hylsa and NSM, to
less than 1 mm. Hot-rolled products are traditionally used in the manufacture of
various non-surface critical applications such as automobile suspension arms,
frames, wheels and other unexposed parts in auto and truck bodies, agricultural
equipment, construction products, machinery, tubing, pipe, tools, lawn care
products and guard rails. The addition of the thin-gauge hot-rolling capability
to the CSP process has opened many traditional cold-rolled applications to
thin-gauge hot-rolled steel producers, including SDI and Hylsa. NSM is designed
to capitalize fully on the significant advancement in thin-gauge hot-rolled
steel production.
 
    COLD-ROLLED PRODUCTS.  Cold-rolled steel is hot-rolled steel that has been
further processed through a pickling/scale removing line and then through a
rolling mill without reheating until the desired gauge and other physical
properties have been achieved. Cold-rolling reduces gauge and hardens the steel
and, when further processed through an annealing furnace and a temper mill,
improves uniformity, ductility and formability. Cold-rolling and temper/skin
pass rolling also impart various value-added surface finishes and textures.
Cold-rolled steel is used in applications that demand a higher quality finish,
such as exposed automotive parts and appliance panels. As a result, cold-rolled
prices are typically higher than hot-rolled prices.
 
                                       57

    COATED PRODUCTS.  Coated steel products are cold-rolled or hot-rolled steels
that have been coated with a non-ferrous metal and/or organic coating to render
them corrosion-resistant and to improve their appearance. Hot-dipped galvanized,
electro galvanized and aluminized products are all types of metallic coated
steels. Coated items are typically the highest value-added flat-rolled products
because they require the greatest degree of processing and tend to have the
strictest quality requirements. Coated steel is used in automotive, appliance,
furniture, roofing, siding, decking, heating and air-conditioning applications.
 
    Other flat-rolled products which are not in the immediate business plan of
NSM are non-coiled flat plate and ultra-light gauge cold-rolled coil, commonly
referred to as tinplate, (i.e., for tinning and subsequent can making). These
products, especially tinplate, are potential future opportunities for NSM.
 
THE WORLD STEEL MARKET
 
    Steel consumption throughout the world has increased significantly over the
past several years from 649 million tonnes in 1990 to an estimated 690 million
tonnes in 1997. This growth trend is expected to continue into the next decade
with steel consumption projected by the International Iron and Steel Institute
to approximate 797 million tonnes in 2005. This represents a 148 million tonne
increase over 1990 consumption levels. Driving this growth is the continued
industrialization of many areas around the world, including the Asia-Pacific
region, with strong consumption patterns in China. In fact, the Asia-Pacific
region taken as a whole is projected to consume almost 80 million more tonnes of
steel in 1997 than in 1990, with China accounting for 49 million tonnes of this
increase.

    Underlying fundamentals leading to this growth projection include the
prospects for fairly low interest and inflation rates for many countries,
including the United States, transferability of technology spurring new factory
construction in countries increasing their industrial base and the need for
continued infrastructure additions and improvements throughout the world.

    If Thailand's economy recovers, its per capita steel consumption may begin
to increase toward the consumption levels of industrialized countries. If steel
consumption in Thailand does increase, the Company believes that being the first
producer of iron metallics (via the DRI facility) and of flat-rolled steel
products (via the Hot Mill) in Thailand will give the Company an economic
advantage over its competitors and facilitate the Company's expansion plans due
to its early entry into the marketplace and ability to establish customer
relations. The Company believes that this advantage could be significant as
Thailand's overall raw steel production on a per capita basis is only 4.3% of
South Korea's, 4.7% of Japan's, 6.3% of Taiwan's and 9.2% of the United States.
 
    In virtually every industrialized country, flat-rolled steel products make
up the largest steel product group, accounting for well over 50% of the total
steel consumed. As a percent of total world steel consumption, flat-rolled steel
consumption has been, and is expected to continue, rising as industrialization
spreads throughout the world. Given the continuing emphasis on critical
applications and higher value added flat-rolled steel products, NSM, with its
low cost structure and high-quality product capabilities, is well positioned to
capitalize on this increasing demand.

    Further demonstrating the increased importance of flat-rolled steel products
is the fact that China's flat-rolled consumption as a percent of its total
apparent steel consumption increased from 23.5% in 1985 to 29.4% in 1996. Thus,
in 1996, China consumed 28.6 million tonnes of flat-rolled steel. By comparison,
the United States' percent of flat-rolled steel consumption increased from 59.2%
in 1985 to 62.9% in 1996. Flat-rolled steel consumption in the United States in
1996 was 67 million tonnes.
 
    The Off-Take Agreements and the commercial assistance agreement that NSM has
entered into with the former chief commercial officer of USSteel will facilitate
its introduction to flat-rolled steel consumers throughout the world. Both
Preussag and Klockner, with their worldwide network of sales offices, will have
opportunities to sell the higher quality and higher priced flat-rolled steel
products produced by NSM.
 
    The consumption of flat-rolled steel products, whether they are hot-rolled,
cold-rolled, coated, plate or tinplate, continues to move towards higher
value-added non-commodity grades as industrialization continues throughout the
world and new steels and new uses for steel are developed. NSM's emphasis on
high-quality products is expected to position it at the forefront of this trend.
 
    FLAT-ROLLED CONSUMPTION IN THAILAND.  Unlike other developing countries,
Thailands' percent of flat-rolled steel consumption is extremely high,
accounting for over 55% of Thailand's 1996 steel consumption. This level of
flat-rolled steel consumption reflects the fact that Thailand is home to a large
number of export-oriented, foreign flat-rolled steel consuming companies.

    As the only producer of flat-rolled steel in Thailand, the Company believes
that it will displace a portion of the flat-rolled products shipped into
Thailand. This belief is based on the fact that the Mill is designed to be a
low-cost producer of a full range of flat-rolled products, including high
value-added products. The Mill's location close to Thailand's flat-rolled
consumers also provides domestic consumers with significant savings in terms of
freight and timeliness of delivery.
 
    Additionally, Thailand's flat-rolled steel consumers tend to consume a
disproportionate amount of higher grade steels. This is reflected by the fact
that vis-a-vis other countries, the price levels paid for imported steel are
significantly higher in Thailand.
 
    The following table shows average recent price levels paid by Thai customers
for imported flat-rolled products. The Company believes that these prices are
substantially higher than world spot market commodity prices and also higher
than typical world high-grade product prices.

    Further facilitating the Company's ability to sell its products
domestically, is the fact that Thailand's flat-rolled consumption base is fairly
diverse, with relatively low dependence on the automotive sector.

THE COMPANY'S PRODUCTS AND APPLICATIONS
 
    The Company will use its Hot Mill to produce an array of hot-rolled products
in 900 mm to 1600 mm widths and in thickness from 13 mm to 1 mm. These products
are suitable for the following applications: mechanical and structural tubing;
gas and fluid transmission piping; metal building systems; parts and components
for automobiles, trucks, trailers, and recreational vehicles; rail cars; ships;
barges; marine and agricultural equipment; farm implements; lawn and garden
equipment; industrial machinery and shipping containers. NSM will also sell its
hot-rolled products to entities such as steel service centers that will provide
further processing. The Company believes that the design and operating
innovations made in its Hot Mill will allow its hot-rolled products to have
surface and edge quality characteristics exceeding those of the vast majority of
other steel mills in the world. As demonstrated by SDI and Hylsa, the CSP
technology produces flat-rolled products with unsurpassed metallurgical
uniformity and superior dimensional tolerances, resulting in improved
manufacturability and yield performance.
 
    After completion of the Finishing Facilities, NSM will produce a full range
of hot-rolled, cold-rolled and coated products. At that time, the Company
expects to devote a substantial portion of its hot-rolled steel (down to 1 mm)
to the production of higher-value added products, including galvanized, as well
as thinner gauge cold-rolled products.
 
MARKETS FOR THE COMPANY'S PRODUCTS
 
    Under the Off-Take Agreements, Preussag and Klockner will be obligated to
purchase, in aggregate, 100% of the Company's production in 1998 through 2002,
and 25% of the Company's production in the years 2001 through 2005. NSM may, at
is option, reduce the percentage of its production sold under the Off-Take
Agreements to as little as 67% in 1998, 50% in 1999 and 25% in 2000, if the
Company believes it could maximize sales revenue through sales to other
customers. Under the Indentures, sales by NSM to customers other than Preussag
and Klockner, to the extent that the aggregate of such sales results in
receivables outstanding in excess of U.S.$10 million, must be supported by
letters of credit if the customer does not have an investment grade credit
rating. All export sales, whether to Preussag, Klockner or other customers will
be U.S.$ denominated. Steel is sold based on internationally accepted product
specifications. Certain orders are anticipated to contain specific application
requirements. Non-compliance with such specifications can result in rejections
and claims against the seller. Such claims are usually settled between the
producer, the trading company and the end user. Claims may result in financial
damage awards against the seller.
 
    Sales outside Thailand are for Preussag's and Klockner's own accounts,
regardless of whether they are purchasing for their own use or for resale. If
the Company receives an unsolicited offer to purchase any products from a
prospective customer outside of Thailand, the Company must notify Preussag and
 
                                       62

Klockner of the terms and Preussag and Klockner will then have a right of first
refusal to effect the purchase.
 
    Preussag and Klockner are large, German-based international steel trading
and processing firms. Preussag's origin dates back to Peine/Salzgitter, an
integrated flat-rolled steel producer that is now part of Preussag AG.
Similarly, Klockner's origin dates back to Klockner Bremen, an integrated
flat-rolled steel producer that is now part of the ARBED/Sidmar group. Both
firms have extensive sales, distribution and steel processing facilities
worldwide. Additionally, they have the in-house metallurgical and product
application expertise to serve the high end of the steel market. The Company's
anticipated ability to produce unique high-quality steel grades including
ferritic hot- and cold-rolled steels have already prompted serious inquiries
from many high-quality users in the transmission pipe, structural tubings and
high-strength re-rolling and parts making industries in Asia, Europe and North
America. The American Petroleum Institute ("API") pipe quality standards are the
worldwide accepted specifications for high-quality pipe products. The Company
believes that it is the only producer in Southeast Asia with the required steel
making and rolling facilities to meet the API's high-quality requirements.
 
    On a global basis, steel trading volume has increased significantly over the
past decade. According to International Iron and Steel Institute statistics, 169
million tonnes of steel were traded in 1985 and 231 million tonnes were traded
in 1996. The Company expects the trend of increasing trading activity to
continue as industrialization continues throughout the world.
 
    Steel consumption in Thailand is expected to be reduced in the near term due
to the economic slowdown in Thailand. Thus, the Company's projections assume 90%
export in 1998 and 50% in 1999. Thailand is undersupplied in terms of steel
production and over time, the Company believes that domestic sales will
increase.
 
SALES AND MARKETING
 
    The Company employs a 12-person direct sales staff, consisting of a manager
of sales and marketing, four field sales managers, two customer technical
service engineers, a quality assurance engineer, and four inside sales and
administration personnel. Similar to SDI, NSM plans on keeping its end user
sales and support staff small and efficient, reflecting its emphasis on
cost-containment and productivity. The expertise of the Company's employees is
being supplemented by a commercial assistance agreement that it has entered into
with Mr. Reuben L. Perin, the former chief commercial officer of U.S. Steel.
This agreement covers marketing, sales, trade and strategic planning issues. Mr.
Perin has been named a director of NSM.
 
                                       63

    The Company's sales team will work in close cooperation with the sales,
metallurgical and product application professionals at Preussag and Klockner to
fully utilize the Company's quality, made-to-order and customer service
capabilities.
 
THE COMPANY'S PRODUCTION EQUIPMENT AND TECHNOLOGY
 
    The Mill's design and technical capabilities are based on advanced
technology in virtually every process step and embody various advancements and
improvements. Additionally, NSM has benefited from the technical expertise of
its equipment and technology providers including ABB Industry Limited,
Mannesmann Demag AG, Intersteel Technology, Inc., Bricmont, Inc., Inductotherm
Corporation, SMS, Siemens AG, INCO, INMETCO and Datel Engineering Company, Inc.
and General Electric Company. Further technical enhancements were made through
the research efforts of Dillingen Steel Works in Germany, the University of
Aachen in Germany, Chulalongkorn University in Thailand and the University of
Stockholm in Sweden. The Company's existing equipment and technology, as well as
the Mill's process design are intended to improve steelmaking speed, efficiency
and output, result in minimum energy and power usage, produce flat-rolled steel
of better consistency and tolerances and deliver higher surface and edge
qualities.
 
    BACKGROUND OF ALTERNATIVE SCRAP SUBSTITUTE TECHNOLOGIES.  DRI is a metallic
product produced from iron ore that is used as an alternative or complementary
feedstock to scrap in the steelmaking process. Of the approximately 30 million
tonnes of DRI produced in 1996, over 90% was produced by methods which utilize
lump form iron ore or pellets that are treated in a direct reduction shaft
furnace with natural gas to reduce the iron oxide to metallic iron. Although
these processes are proven to work commercially, suitable ore grades and iron
ore pellets tend to command a premium over iron ore fines. Additionally, natural
gas is typically more expensive than using coal as the reductant. Consequently,
NSM elected to utilize technology which permits the use of low-cost iron ore
fines and medium-quality, medium sulfur coals which are available in abundance
throughout the Asia-Pacific region. Long-term supply contracts for iron ore
fines and coal are in place.
 
    THE DRI FACILITY.  The DRI Facility consists of the design, construction,
and operation of a facility for the manufacture of DRI for use by NSM as a scrap
substitute. The Company studied and considered many alternative methods of
securing a low-cost captive source of scrap substitute material. The existing
commercial processes differ from the DRI Facility's design by the type of raw
feedstock they employ and the type of reductant that is used to "reduce" the
feedstock to useable iron units. The Company will use the INCO/Inmetco DRI
process, which uses low-cost iron ore fines that are ultimately reduced to DRI
in a rotary hearth furnace using medium-quality coal as the reductant.
 
    The selection of the INCO/INMETCO coal-based DRI process, was made
commercially feasible for use by NSM through the adoption of the well proven
German technology of desulfurization of liquid steel via strong ladle stirring
and certain slag practices. To produce DRI, the Company will use low-cost iron
ore fines, which will be combined with ground coal, mixed with a bentonite
binder and other fluxes, and then pelletized. The resulting "green" pellets will
be fed into a rotary hearth furnace, where they will be heated to 1,300 DEG.C
for approximately 15 minutes, after which they will be removed by water-cooled
screws to refractory-lined containers. The containers will be transported to the
Hot Mill and the DRI will be hot-charged directly into the EAF at 900 DEG.C.
 
    The DRI Facility is under construction and scheduled to commence operation
in the second quarter of 1999. A waste heat recovery and the Co-Gen Facility
will be constructed alongside the DRI Facility. The Co-Gen Facility will further
improve NSM's operating efficiency by lowering the Mill's net energy
consumption. NSM and Enron International, Inc., a subsidiary of Enron, have
negotiated terms for the LOI contemplating, subject to definitive documentation,
that Enron International will provide either lease financing or a BOOT contract
for the Co-Gen Facility. U.S.$20 million of the construction costs for the
Co-Gen Facility will be funded by Enron. Enron and NSM have agreed to work
together to obtain the
 
                                       64

remaining funds necessary to complete construction of the Co-Gen Facility.
Infrastructure and certain process equipment has also been designed into the
Co-Gen Facility to support potential expansion to 1.5 million tonnes of annual
DRI and an additional 60 MW of power from waste heat recovery. If expanded and
when operational, after additional expenditures of approximately U.S.$100
million in the DRI Facility and U.S.$170 million in the Hot Mill, the expanded
DRI and steelmaking capacity is projected to reduce the Company's costs of
production by approximately U.S.$65 per tonne for hot-rolled coil.
 
    THE ELECTRIC ARC FURNACE.  The Company's EAF is a 180 metric tonne capacity
tap weight, 325 tonne gross weight, technologically advanced furnace that has
been designed to maintain a hot heel of at least 145 tonnes of raw liquid steel.
The EAF, which is being supplied by Mannesmann Demag, is a ConSteel type
AC-powered 130 MVA high-reactance continuous charging eccentric bottom tap
furnace. It is equipped with a reactor on the primary side of the transformer
and all necessary filters and controls to meet international flicker and
harmonics standards and to minimize peak load on the grid.
 
    NSM's EAF design and the ConSteel Process results in continuous melting and
significantly reduces the tap-to-tap time (I.E., the length of time between
successive melting cycles or "heats"). In a conventional single shell EAF with a
60-minute tap-to-tap time, typically 10 to 15 minutes is taken to tap liquid
steel, insert gun refractories into the side wall of the furnace, re-sand and
repair the tap hole and recharge the vessel with scrap. By eliminating the
requirement to recharge the scrap, and reducing the time needed to perform the
other steps through the use of ConSteel Process, NSM gains an approximately 20%
increase in productivity by reducing the tap-to-tap time to under 50 minutes.
 
    Preheating of scrap will also occur in the ConSteel Process. The source of
energy for the preheating is the latent heat and energy from post combustion
gases exhausted into the containment system from the EAF. No natural gas is used
in the ConSteel Process. A downstream waste heat boiler to be added as part of
the DRI will further reduce NSM's net energy consumption.
 
    Additional attractive features of the ConSteel Process are the significant
reduction of dust generation and emissions as well as a higher production yield
due to continuous "flat bath" melting and stable slag formation.
 
    LADLE METALLURGY.  NSM's ladle design with its extra high freeboard,
dolomitic lining and large porous plugs for Argon stirring are unique features
of the Hot Mill. NSM's ladle design allows for the production of a full range of
steel products while achieving very high levels of steel cleanliness, precision
chemistry control and low levels of non-metallic inclusions.
 
    The Company has two separate ladle furnaces, two VOD's with a common vacuum
system, extensive alloy handling and feeding systems and precision wire alloy
feeding units. These attributes make the Hot Mill one of the most
technologically advanced steelmaking operations in the world. Specific
improvements over other steelmaking operations include NSM's ability to maximize
the time that the EAF can be used for scrap and DRI melting, while enabling the
raw liquid steel to continue through metallurgical testing, stirring, alloying
and sulfur, nitrogen, hydrogen, phosphor, oxygen and non-metallic inclusion
removal. In addition to these activities, temperature and other refinements to
the raw liquid steel continue all the way through to the casting deck. Once at
the casting deck, the liquid steel, which is now considered refined, is emptied
into the tundish in a continuous process and then directly poured into the
casting machine mold via a submerged entry nozzle ("SEN").
 
    THE THIN-SLAB CASTER.  NSM's thin-slab caster was designed and built by SMS
and is equipped with a hydraulically oscillating mold and an electromagnetic
brake to reduce turbulence in the mold. These features, along with a
metallurgical length of eight meters, facilitate NSM's ability to produce
high-quality steels at casting speeds up to eight meters per minute. The caster
also has liquid core reduction capabilities which enable the caster to cast
slabs in a range of thicknesses from 40 mm to 70 mm. This feature, which was
first implemented by SDI, is designed to enhance steel quality and facilitate a
more diversified product
 
                                       65

offering by providing for "soft reduction" on segregation sensitive grades and
improving thin-gauge hot-rolling capabilities.
 
    The caster is also equipped with an SEN designed by SDI and SMS. This design
permits the walls of the SEN to be thicker, which results in longer SEN life
which, in turn enables the Company to run a "string" of 12 heats before the SEN
requires replacement. In contrast, most SENs in operation today require
replacement after 10 heats. These advantages directly increase productivity.
Within the SEN, NSM has also incorporated a new baffle design to modify the
fluid flow of refined liquid steel into the mold cavity. These baffles slow and
more evenly distribute the refined liquid steel into the mold as compared to
previous designs. This results in a quieter top surface, or meniscus, of the
refined liquid steel in the mold, producing a more uniform solidification of the
shell and effectively eliminating sub-surface inclusions.
 
    THE HOT-ROLLING MILL.  The Company's rolling mill is a state-of-the-art,
six-stand rolling mill designed and built by SMS with provisions for a seventh
stand. The operating procedures of the rolling mill begin when the
Bricmont-supplied tunnel furnace receives a cut-to-length slab from the CSP
caster at casting speed. The tunnel furnace equalizes the slab's temperature
profile to a differential of plus or minus 10 DEG. C along the slab's length,
through its thickness and across its width. The excellent temperature profile of
the slab provides optimum conditions for the subsequent rolling process and thus
ensures an excellent profile, flatness and metallurgical uniformity of the
hot-rolled steel. The rolling mill is equipped with a specially designed
high-pressure (up to 400 bar) water descaling system to remove mill scale after
the steel emerges from the tunnel furnace just before entering the rolling mill.
This system provides an exceptionally clean surface on the steel slab while
minimizing the cooling of the 1100 DEG.C slab.
 
    Once in the rolling mill, the slab thickness is reduced down to the required
level while at all times maintaining proper temperature control. The rolling
mill is equipped with the latest electronic and hydraulic controls including
hydraulic roll-gap setting systems. For control of the strip profile and
flatness, all mill stands are equipped with the SMS Continuous-Variable-Crown
System, which uses axially shiftable work rolls, in combination with work roll
bending. The run out table, with laminar spray cooling, was especially designed
for precise cooling of extremely thin-gauge steel. The Company's closely-spaced
rolls and advanced guidance system on the run-out table help to prevent the
steel from cobbling when rolling lighter gauges. NSM's Number 1 down-coiler is
located only 20 meters from the last stand of the rolling mill to allow accurate
coiling and temperature control of thin gauge steel. The capability to roll at
low temperature (ferritic rolling) and to coil thin-gauge steel at high coiling
temperatures gives NSM unique product capabilities and is a principal advantage
of NSM's short coupled coiler. The Number 2 down-coiler is located 85 meters
from the last stand to provide full controlled laminar cooling of heavier gauge
steel. The coiled steel is moved by an automated coil handling system to either
the shipping warehouse for conventional cooling before loading onto trucks for
shipment or to the accelerated coil cooling system where they are cooled to
ambient temperature in three hours for further processing in the Finishing
Facilities or for faster delivery to customers.
 
    Throughout the rolling process, laser optical measuring equipment and
multiple x-ray devices measure all dimensions, allowing adjustments to occur
continuously and providing feedback information to the Mill's process controls
and computers. All positioning and control equipment used to adjust the rolling
mill is hydraulically operated and regulated electronically to achieve a high
degree of accuracy and repeatability. The entire production process is monitored
and controlled by both business and process computers. An additional flatness
control system is being installed in the rolling mill which will utilize proven
cold mill technology to improve light gauge flatness control for direct shipment
from the Hot Mill.
 
    Production schedules are created based on order input information and
transmitted to the Mill's computers by the plant business system. Mathematical
models then determine the optimum settings for the tunnel furnace, the
hot-rolling mill and the cooling sprays. This information is then directly
transmitted to the equipment controlling the rolling operations. As the material
is processed, operating and quality data are gathered and stored for analysis of
operating performance and for documentation of product
 
                                       66

parameters. The system then coordinates and monitors the shipping process, and
prints all relevant paper work for shipping when the steel leaves the Mill.
NSM's off-take partners Preussag and Klockner, will directly tie-in to NSM's
operating systems to further ensure maximum operating efficiency and customer
service.
 
    THE FINISHING FACILITIES.  The Finishing Facilities, which are being
constructed adjacent to the Hot Mill, will consist of: (i) a
combination/multipurpose continuous pickling, cold-rolling, cleaning, annealing,
hot-dip galvanizing, skin pass/tension leveling and oiling line, supplied by SMS
(the "Combination Line"), (ii) a push-pull pickling/trimming/oiling line (the
"Push-Pull Line"), (iii) hydrogen batch annealing furnaces, and (iv) a
recoil/temper rolling/slitting line, also supplied by SMS (the "Recoil Line").
 
    The Combination Line will receive hot-rolled steel from the Hot Mill by a
dedicated coil conveyor. The line consists of three independent yet integrated
sections, the entry section, process section and exit section, each of which is
separated by a storage accumulator to provide continuous operation. The entry
section equipment includes dual pass lines to permit loading of hot-rolled steel
while simultaneously running on the other pass line. The process section
consists of equipment to remove scale, reduce thickness, clean, anneal, coat,
skin pass, correct flatness, side-trim and apply oil. A by-pass allows for
pickling or pickling and cold-rolling without the strip having to pass through
the galvanizing process. The pickling section uses three shallow pickling tanks
containing hydrochloric acid and a multiple stage rinse tank to remove mill
scale. A fume exhaust system is provided to extract fumes from the pickling and
rinse tanks and prevent the escape of fumes into the building. After leaving the
pickling process, the pickled steel passes into the two-stand four-high cold
rolling mill for thickness reduction. Entry and exit thickness gauges, load
cells and other related equipment in combination with a high-precision mass flow
control model provide automatic gauge control to exact tolerances. After leaving
the cold rolling mill, further processing consists of cleaning the cold-rolled
steel in a cascade alkaline cleaning and water rinse to remove any residual
rolling oils and iron fines before entering the heating and annealing furnace.
Next, in the heating and annealing furnace, the cold-rolled steel is heated to
750 DEG.C to recrystallize the cold-rolled grain structure and then cooled to
the galvanizing pot temperature in a protective nitrogen/hydrogen atmosphere. In
the event that the gauge of the steel does not need to be further reduced and
the cold-rolling mill is bypassed, the steel is only heated to the 450 DEG.C
temperature of the galvanizing pot. For galvanizing purposes, an immersion roll,
stabilizing rolls, and air knives and blowers are provided to automatically
control the coating weight of metal on the strip. After passing through a
cooling tower, water quench tank, and strip dryer, the galvanized coated steel
is skin passed on a four-high mill to improve strip luster and surface
smoothness and tension leveled to correct strip flatness suitable for shipping.
 
    The Push-Pull Line will also receive coils from the Hot Mill by a dedicated
coil conveyor. The Push-Pull Line consists of an entry section with a pay-off
reel, a flattening machine, crop shear and a taper shear for preparing the
head-end of the steel. Pickling is carried out in the process section in a
"cascade-type operation" in three stages in which the acid flows counter-current
to the strip pass. The pickled steel leaves the pickling tank via a driven
squeeze roll set and passes into a four-stage counter-current cascade rinse
section and a hot air dryer. Threading is carried out by means of driven squeeze
and transport roll sets. The exit section consists of a loop pit, a pinch roll
set, a side-trimmer, a three-roll bridle, an oiler and a recoiler.
 
    Cold-rolled steel not requiring galvanizing will proceed to the batch
annealing furnaces to reduce the hardness of the steel that is created in the
cold rolling process. The batch annealing furnaces will heat the steel, in order
to soften it, in a hydrogen environment that optimizes the efficiency of the
heating process and produces a product that is superior compared to conventional
annealing furnaces. The batch annealing units heat and then cool the steel in a
controlled batch system for optimum cleanliness and uniformity of metallurgical
properties. Certain grades of cold-rolled steel will be produced in-line on the
Combination Line, by-passing the galvanizing section.
 
                                       67

    Product from the annealing furnaces will then be temper-rolled in the Recoil
Line. The Recoil Line is a single stand four-high mill designed for relatively
light reduction. The line includes a slitting/side-trimming and inspection
station as well as an oiling unit. The Recoil Line introduces a small amount of
hardness into the product and further improves the flatness and surface quality
of the product.
 
    In a manner similar to the Hot Mill's process computers, the Combination
Line, Push-Pull Line, annealing furnaces and Recoil Line will be linked by means
of business and process computers. The business systems will be expanded to
include order entry of the additional finished products. All scheduling will be
accomplished in the business computer systems, with schedules transmitted to the
appropriate process related computers. Operating and quality data will also be
collected for analysis and quality control purposes, and for reporting product
data.
 
STEEL SCRAP AND SCRAP SUBSTITUTE RESOURCES
 
SCRAP ANALYSIS
 
    Scrap is the most significant raw material in the Company's steelmaking
process representing approximately 32% of the fully loaded cost per tonne of
hot-rolled coil. There are many grades of scrap, but the two main
classifications are obsolete scrap and prompt industrial scrap.
 
    Obsolete scrap is derived from discarded goods including agricultural and
construction equipment, automobiles, construction trash, abandoned military
equipment, appliances, container drums and miscellaneous pieces of steel.
Historically, the collection of obsolete scrap has tended to be a peddler
industry, with collection rates increasing dramatically in periods of economic
distress. This is especially true in developing countries. Collection rate
swings continue based on economic conditions until an efficient collection
system develops. Developed countries such as the United States have efficient
collection systems in place which tend to operate more steadily throughout
economic cycles.
 
    Obsolete scrap comes in many different forms. None are free of metallic
contamination, otherwise known as residual elements. Copper comes from wire
mixed into the scrap or from copper deliberately added to some steels for
corrosion protection. Other residuals include nickel, chromium and molybdenum
contained in various steels for strengthening and toughness purposes, or added
as a coating for decorative or corrosion resistant purposes. The elements
copper, nickel and tin, and to a great extent, chromium and molybdenum cannot be
refined out of steel once they are dissolved into it. The only obsolete scrap
that is relatively low in residuals comes from either old structurals and rails
that were made from Bessemer and open-hearth steel with high iron content or
well sorted and processed shredded scrap from automobiles and other consumer
goods. Unfortunately, the amount of this steel recovered each year is extremely
limited. This is especially true in a country such as Thailand that is in the
early stages of its industrial development. Thus, the value of obsolete scrap in
EAF flat-rolled steelmaking is limited. Unlike most flat-rolled steelmakers
utilizing EAFs, NSM will be able to consume a certain amount of obsolete scrap
in its meltmix due to the fact that the DRI produced in the DRI Facility will be
high in iron content and low in contaminants or residuals.
 
    Prompt industrial scrap is produced as a by-product of various metal working
operations. Steel fabricators, machine shops, stamping plants and auto
production operations, such as those being built and operated in close proximity
to NSM, all generate this type of scrap. Prompt industrial scrap is the most
desirable for EAF steelmaking due to the traceability of its origin.
Approximately 15% of prompt industrial scrap is in the form of turnings.
Unfortunately, most turnings are contaminated with high levels of sulfur oil and
are high in alloy content. Thus, turnings do not represent a source of
low-residual material. Structural and plate scrap generated from fabrication
operations amount to approximately 10% of prompt industrial scrap. Structural
and plate prompt industrial scrap is primarily made from obsolete scrap and, as
such, does not represent a source of low-residual material. The remaining 75% of
prompt industrial scrap is in the form of bundles, clips and bushelings, all of
which are low in residuals. NSM plans to consume initially approximately 25% of
prompt industrial scrap in its melt mix, with the remaining mix consisting of
DRI 20%, pig iron 20% and obsolete scrap 35%. This mix will be adjusted
depending on the price of these materials.

    The table below provides an overview of the typical and range levels of
residuals in various grades of scrap as would be found in a mature industrial
economy such as the United States. EAF flat-rolled steel producers requiring
approximately 0.22% residual level need to melt a significant portion of
bundles, clips and bushelings or supplement their melt mix with DRI, pig iron or
other scrap substitutes. The Company expects that its advanced steel refining
and reduction of sulphur, nitrogen and non-metallic inclusions, combined with
low temperature ferritic rolling, will allow it to tolerate higher residual
concentrations.

    SOURCE: GORDON H. GEIGER, T.P. MCNULTY AND ASSOCIATES, "SCRAP SUPPLY: IS
THERE ENOUGH OF THE RIGHT KIND?", PRESENTED AT THE GORHAM/INTERTECH CONFERENCE
ON "IRON AND STEEL SCRAP SUBSTITUTES," ATLANTA, GA, APRIL 27-29, 1994.
 
    Various studies have shown that the amount of prompt industrial scrap
generated equals approximately 12-20% of steel consumption, depending on scrap
collection and processing practices. For example, in a year when the consumption
of steel equals 10 million tonnes, approximately 1.2 to 2 million tonnes of
prompt industrial scrap will be generated. Of this amount, 75% represents
low-residual tonnes. Thus, the amount of low-residual scrap available in a
country in a year when 10 million tonnes of steel is consumed is 900,000 to 1.5
million tonnes. Thus, in a country such as Thailand where the scrap collection
and processing practices are not fully developed it can be estimated that
900,000 tonnes of low-residual scrap will be available for consumption. The
Company believes that it will be able to purchase approximately 420,000 tonnes
of locally generated low-residual scrap each year during its first years of
operation. This amount is expected to increase over time as Thailand's scrap
collection and processing system matures and the amount of steel consumed in
Thailand increases. Recognizing that Thailand's scrap collection and processing
system is still developing and no efficient export mechanism exists, NSM
believes that locally generated scrap will be available at a U.S.$20-30 per
tonne discount to world market prices.
 
    To supplement the amount of locally generated low-residual scrap available
to it, NSM will purchase scrap on the world market. Many industrialized
countries including the United States, Germany and Japan are net exporters of
scrap. Scrap is a worldwide surplus commodity and its price and availability are
dictated by its supply and demand as well as the price and availibility other
traded metallics, including pig iron, DRI, and others.
 
                                       69

DRI ANALYSIS
 
    The most commonly used scrap substitute is DRI, with over 33 million tonnes
consumed in 1996. DRI is produced through a direct reduction production process
in which oxygen is removed from iron ore in a solid state leaving a metallic
iron product. DRI, unlike scrap and some other scrap substitutes, contains no
nonferrous residuals such as copper, nickel, tin, chromium or molybdenum. There
are two methods of producing DRI, gas-based DRI production and coal-based DRI
production. The DRI Facility will utilize the coal-based DRI production method.
SDI intends to employ a coal-based DRI production method in its Iron Dynamics,
Inc. project.
 
    Gas-based DRI production, which was first commercialized in the early
1970's, accounted for the vast majority of the world's DRI production in 1996.
Gas-based production methods combine pre-treated iron ore that is fed into the
top of a shaft furnace with reformed natural gas that is injected into the
bottom of the shaft reactor. As the pre-treated iron ore flows down and the
reducing gases that are flowing up come in contact with each other the carbon
monoxide and hydrogen in the gas reduces the iron ore to form metallic iron.
 
    NSM designed its DRI Facility to operate under the coal-based method of
production to take advantage of the potentially significant operating savings
associated with coal-based production and to avoid the capital costs associated
with running a pipeline from Burma or the South China Sea, the nearest natural
gas supply. The DRI Facility is based on the INCO/INMETCO DRI design. INCO, the
world's largest nickel producer headquartered in Toronto, Ontario, through its
wholly-owned subsidiary Inmetco has operated a coal-based direct reduction
facility for recycling purposes since 1979. Utilization of the INCO/Inmetco
design for DRI production was made commercially viable by adding well proven
desulfurization slag practices into the steel making process. These additions
will provide NSM with the ability to significantly reduce the cost of DRI
production through the use of low-cost iron ore and lower cost medium-quality,
medium sulfur coals. With gas-based DRI processes, only the highest grades, and
most expensive, iron ore and special low sulfur coals can be used. To supplement
its DRI production, NSM has entered into a technology and process license with
Inmetco that provides NSM with access to operating enhancements.
 
ENERGY RESOURCES
 
    NSM has entered into various arrangements to ensure its access to and
availability of electric power, natural gas, oxygen, coal and iron ore. NSM has
entered into arrangements under which PEA and PTT will provide NSM with electric
power and natural gas. Both PEA and PTT are government entities charged with
providing electricity and natural gas, respectively, to Thailand's industrial
base. The Company will benefit from two new power substations adjacent to the
Mill and from two sets of new power lines which run to the Mill site all
recently constructed by PEA. The Company has access to a long-term supply of
oxygen and other industrial gases from Bangkok Industrial Gas which has recently
constructed an oxygen plant adjacent to the Mill. Coal and iron ore, two
important raw materials needed to produce DRI, are being supplied by SSM and
MMTC under long-term contracts.
 
COMPETITION
 
    The Company has various competitors within the global steel industry.
Generally, the markets in which the Company participates are highly competitive.
The competitive nature of the industry in the future could have an adverse
effect on the business, financial condition, results of operations or prospects
of the Company. The Company competes primarily on the basis of price, quality,
and the ability to meet customers' product specifications and delivery
schedules. Many of the Company's competitors are integrated steel producers
which are larger in terms of steel making capacity, have substantially greater
capital resources and historical operations and, in some cases, have lower raw
material costs than the Company. In addition, competition may increase as a
result of excess capacity created by other producers using mini-mill technology
and traditional steelmakers who are making their operations more efficient. For
example, several new mini-mills began production in the United States in 1997.
The highly competitive nature of the global steel industry, combined with excess
production capacity in some products, may in the future exert downward pressure
on prices for certain of the Company's products. The deterioration in the
economics of
 
                                       70

Southeast Asia may exert downward pressure on prices for the Company's products
if regional competitors choose to lower their prices in order to maintain
revenues in the face of decreasing regional demand for steel products. Although
the Company believes that it is well-positioned to compete in the markets where
it operates, competitors may develop new products or production processes that
could provide advantages to such competitors to the detriment of the Company.
There can be no assurance that the Company will be able to compete effectively
in the future. In addition, in the case of certain product applications, steel
competes with other materials, including plastics, aluminum, graphite
composites, ceramics, glass, wood and concrete. There can be no assurance that
the Company will be able to compete effectively in the future. See
"Business--Competition."
 
    NSM is the only flat-rolled steel producer in Thailand. There are however,
two flat-rolled rerolling entities currently in operation in Thailand.
Sahaviriya Steel Industry, a Thai-based company, commissioned a re-rolling mill
in 1994. The Sahaviriya mill has a designed capacity of 2.4 million tonnes per
year, but only rolled 1.2 million tonnes in 1996. LPN Plate Mill, another
Thai-based Company, commissioned a reversing plate mill in 1996. The LPN mill
has a designed capacity of 600,000 tonnes per year. Siam Strip Mill, a
Thai/Japanese joint venture, has announced plans to bring on-line 1.7 million
tonnes per year of hot-rolling capacity in 1999.
 
FACILITIES
 
    The Mill is situated on a 220-acre site in Chonburi, Thailand, strategically
located in Thailand's Eastern Seaboard, the heart of Thailand's industrial
development. Modern highways connect the plant to domestic customers and the
recently constructed deep seaport of Sriracha Harbor. Two 115,000 volt
transmission lines bring electrical power to the Company's own electrical
sub-station. Water is supplied from a 576,000 m(3) reservoir located adjacent to
the Mill and is supplemented by a 15 m(3)/minute water supply line from the
Chonburi Industrial Estate for backup. Water from this reservoir is pumped to a
service water piping system that links the reservoir to the various water
treatment facilities that support the Mill.
 
    There are three main buildings that comprise the Hot Mill. These are the
melt shop building, the tunnel furnace building and the rolling mill building
which includes the shipping area. Within the Hot Mill, the melt shop building
contains two 350-tonne cranes and two 40-tonne cranes. The tunnel furnace
building contains a 20-tonne crane and the rolling mill building contains two
100-tonne cranes, four 60-tonne cranes and a 20-tonne crane.
 
    The Finishing Facilities and the DRI Facility will both be located adjacent
to the Hot Mill to facilitate efficient steelmaking. Similar to the Hot Mill,
the Finishing Facilities will contain several cranes to maximize the Company's
ability to implement just-in-time delivery schedules.
 
    Office buildings on site will include a general administrative corporate
headquarters building, consisting of 1,100 square meters, a building for the
engineering, management information systems and training personnel, consisting
of 1,100 square meters, and an employee services building consisting of 1,310
square meters which includes shower and locker room facilities, as well as the
plant cafeteria.
 
    Other support facilities include emission control and water treatment
systems. The primary emission control unit is the meltshop bag house which
captures the gasses from the melting operation and cleans them to comply with
U.S. type emissions standards. The bag house is capable of cleaning 50,000
m(3)/minute of these gasses. The water treatment system cleans, cools, and
recirculates the water used by the plant in various processes at the overall
rate of 500 m(3)/minute.
 
    To reduce the risk of equipment failure, NSM follows comprehensive
predictive and preventative maintenance programs, has on-site maintenance and
repair facilities, and maintains an inventory of spare parts and machinery. For
example, the Company maintains spare caster parts, mechanical parts and
electrical controls for its cranes and other tools. The Company believes that it
maintains adequate property damage insurance to provide for reconstruction of
damaged equipment, as well as business interruption insurance to mitigate losses
resulting from any production shutdown caused by an insured loss.
 
    The Company considers its facilities adequate for its needs.
 
                                       71

    The Company's executive offices are located at Chonburi Industrial Estate
(Bowin), 358 Moo 6, Highway 331, Sriracha, Chonburi 20230 Thailand and its
telephone number is (66-38) 345-950, facsimile number is (66-38) 345-375.
 
ENVIRONMENTAL MATTERS
 
    The Company's operations are subject to substantial and still evolving Thai
environmental laws and regulations concerning, among other things, emissions to
the air, discharges to surface and ground water, noise control and the
generation, handling, storage, transportation, treatment and disposal of toxic
and hazardous substances. NSM believes that its facilities are in material
compliance with all provisions of Thailand's environmental laws and does not
believe that future compliance with such provisions will have a material adverse
effect on its financial condition or results of operations. The Company intends
to obtain ISO 14000 environmental certification for its facilities.
 
EMPLOYEES
 
    The Company's employees are not represented by labor unions. The Company
believes that its relationship with its employees is good.
 
RESEARCH AND DEVELOPMENT
 
    The Company has agreements with two universities, the Technical University
in Aachen, Germany and Chulalongkorn University in Bangkok for assistance in
research and development activities. Through these agreements, NSM employees
have access to the equipment and considerable knowledge base at both
institutions. It is anticipated that NSM's research will focus on the
development of new steelmaking and DRI processes and value added steel products.
The Company believes that these agreements will help provide a competitive edge
over most other steel producers.
 
AFFILIATE TRANSACTIONS
 
    The Company is one of a number of affiliated companies which are involved in
various aspects of the steel industry which have directors common to their
respective boards of directors. Several of the directors of the companies have
direct and/or indirect investments in each of these companies. In addition, some
of these companies also have direct and indirect investments in each other. A
number of arrangements and transactions have been entered into from time to time
between such companies. It has been the intention of the affiliated companies
and the respective boards of directors that each of such arrangements or
transactions taken as a whole should accommodate the respective interests of the
relevant affiliated companies in a manner which is fair to both parties and
equitable to the shareholders of each. Under corporate law in Thailand,
directors of a company are required to act at all times in the best interests of
the shareholders with respect to transactions entered into by the company. In
addition, corporate law in Thailand places certain limitations on the ability of
a public company to enter into related party transactions.
 
    Because of the scope of the relationships that exist between the companies,
there can be no assurance that such agreements or transactions entered into, if
considered separately, have been or will be effected on terms no less favorable
to the Company than could have been obtained from non-associated third parties.
While any future arrangements are expected to be subject to approval by the
Company's Board of Directors and, where appropriate, the approval of
shareholders and Management Co. there can be no assurance that the future
arrangements between the Company and the other associated companies will not
involve conflicts of interest.
 
CONTINGENCIES AND LEGAL PROCEEDINGS
 
    In August 1996, the Company entered into an agreement with Nucor whereby
Nucor would provide training and data relating to the business processes that
the Company would use in its operations in Thailand (the "1996 Agreement"). As
compensation for these services, Nucor was to be reimbursed its out-of-pocket
expenses and, depending on the Company's financial performance (assisted by
Nucor), was to have received cash of between $5 million and up to $15 million,
and options to purchase (for the lesser
 
                                       72

of 75% of market or 16 Baht per share) a minimum of 2 1/2% and up to 5% of the
Company's shares outstanding at the date of exercise.
 
    Nucor delivered a termination notice on October 27, 1997, claiming default
in payment. Nucor reiterated its claim in a subsequent letter asserting rights
to payment of $12.5 million and to stock options in the maximum amount provided
for under the agreement. The Company believes that Nucor's October 27, 1997
notice of termination was invalid.
 
    Disputes under the 1996 Agreement are to be resolved through arbitration. No
arbitral demand has been made by either Nucor or the Company at this time. The
Company does not believe it has any further obligation to Nucor for compensation
and/or stock options. Should an arbitration be commenced, the Company believes
it will prevail and no further compensation would be due Nucor.
 
    The Company and Koch Mineral Services, Inc., ("Koch") have engaged in
certain negotiations concerning Koch's potential equity participation in or
management of Sriracha Harbor, its potential equity participation in NSM and
certain agreements concerning the supply of raw materials or the provision of
transportation services by Koch. Notwithstanding such negotiations, Koch will
not acquire shares of NSM in connection with the Transactions. To date, the
Company has reached no agreement with Koch regarding any potential equity
participation in either NSM or Sriracha Harbor or the supply of raw materials or
the provision of transportation services by Koch, but the Company will continue
to respond to Koch's requests for information. Koch has informed the Company
that it may seek U.S.$500,000 as liquidated damages under a letter regarding
Koch's potential equity participation in NSM or Sriracha Harbor. The Company
does not believe it is liable for such liquidated damages.
 
    Currently and from time to time the Company is involved in litigation
incidental to the conduct of its business, but it is not a party to any other
lawsuit or proceeding that, in the opinion of the Company, is likely to have a
material adverse effect on the Company.
 
TRANSPORTATION
 
    The Company expects to receive all of its imported raw materials and deliver
most of its finished product by ship. The Company intends to make use of
Sriracha Harbor for the majority of these shipping transactions. Sriracha Harbor
is located approximately 15 miles from the Mill and is owned by Sriracha Harbour
Public Company Limited, an affiliate of NSM. NSM intends to enter agreements
with the management of the harbor to protect access to the harbor for NSM's
shipments.

BOARD OF INVESTMENT
 
    The Company derives substantial economic benefits from the promotional
considerations granted to it by the Board of Investment. Such benefits include
the permission to bring foreign experts into Thailand and the exemption from
certain import duties and taxes. Additionally, the BOI has only granted two
licenses for the production of steel products in Thailand. The continued
availability of these economic benefits for the Company is conditional upon the
on-going satisfaction of certain requirements. Failure to satisfy these
requirements may result in the loss of economic benefits. The tax advantages
granted by the BOI, as well as certain limitations on foreign ownership, expire
seven years following the start of commercial operations for the hot iron plate
and DRI, and eight years for the finishing facilities. The Company agreed in the
Warrant Agreement that the Company will not issue any Ordinary Shares or other
equity interests to any holders if the Company is aware (taking into account its
ability to access relevant information) that the effect of such issuance would
be, assuming the immediate exercise of all then outstanding Warrants, to cause
the Company to exceed the Foreign Ownership Percentage (as defined). See "Risk
Factors--BOI Compliance."

                      DESCRIPTION OF PROJECT PARTICIPANTS
 
SDI
 
    SDI owns and operates a new, thin-slab/flat-rolled steel mini-mill, which
commenced operations in January 1996. SDI was founded by executives and managers
who pioneered the development of thin-slab/ flat-rolled technology and directed
the construction and operation of the world's first CSP thin-slab/flat-rolled
mini-mill. Building upon their past experience with thin-slab/flat-rolled steel
technology, management founded SDI with the intention of combining a
state-of-the-art CSP thin-slab hot mill with a coal-based DRI facility and
certain downstream finishing facilities. Employing SMS designed technology
similar to that employed by the Hot Mill and utilizing many of the same training
programs and compensation incentive systems implemented by NSM, SDI successfully
completed start-up and ramp-up of its hot mill. SDI's finishing facilities are
currently in the start-up phase and its coal-based DRI facility is under
construction with a scheduled start-up date in the third quarter of 1998. SDI
has consistently produced high-quality flat-rolled steel products, including
low-carbon thin-gauge steel products. Additionally, SDI is among the lowest cost
producers of flat-rolled products. In the third quarter of 1997, SDI's seventh
quarter of operation, SDI's operating profit (pre-tax income before interest and
start-up costs) was U.S.$67 per short ton. SDI has sold a certain amount of its
flat-rolled production under long-term off-take contracts to several steel
consumers and trading companies, including Preussag.

SMS
 
    SMS, a German-based equipment manufacturing and design firm, is 51% owned by
MAN Aktiengsellschaft, a Deutsche Mark ("DM") 21 billion revenue company, and
49% owned by Siemag Weiss Stiftung and Co. KG, a company with steel mill
equipment manufacturing and design expertise dating back to 1856. SMS is a
leader in providing CSP thin-slab/flat-rolled mini-mills to the steel making
community. With turnover in excess of DM2.7 billion, SMS has sold and helped
commission 11 CSP thin-slab/flat-rolled mini-mills. Included among this group
are Hylsa's mini-mill and SDI's mini-mill. SMS commercialized the world's first
CSP thin-slab/flat-rolled mini-mill in 1989 when SMS's proprietary technology
successfully proved that flat-rolled products could be produced using a mold
design that cast a 50 mm slab rather than the 250 mm slab commonly produced.
SMS's revolutionary technological breakthrough was the culmination of over four
decades of research and paved the way for the modernization of the world's flat-
rolled steel making community. Since 1989, SMS has continually developed
technological enhancements so that today SMS's CSP thin-slab/flat-rolled
mini-mills are capable of producing a full range of high-
 
                                       76

quality flat-rolled products. NSM's Mill is considered by SMS to be among the
most advanced CSP thin-slab/flat-rolled mini-mills ever built.

world of significant steel trading activity for Preussag include the Middle
East, Africa and the United States. On a worldwide basis, Preussag had revenue
of approximately DM4 billion for the year ended December 31, 1996 with over
DM2.8 billion of this amount related to steel trading. The remaining portion was
related to steel service center activities in North America, which include the
off-take agreement entered into between Preussag and SDI. An important component
of Preussag's business strategy is the establishment of off-take arrangements
with high-quality, low-cost producers of flat-rolled steel. Building on this
strategy, Preussag has entered into an eight-year off-take agreement with NSM.

    The Shareholders' Agreement restricts the transfer of NSM shares by any of
the parties thereto, except with respect to 3,667,750 newly issued shares
purchased by McDonald which may be transferred to an investor in the Debentures.
The Agreement provides that (i) prior to the first anniversary of the closing
date of the Shareholders' Agreement (the "Closing Date"), no party to the
Shareholders' Agreement may transfer any shares of NSM (except pursuant to any
pledge of such shares in effect on the date the
 
                                       80

Shareholders' Agreement is signed) except that the Thai Parties may collectively
transfer certain shares; PROVIDED that, after giving effect to the aggregate of
all such transfers, the New Equity Investors and the Thai Parties shall, in the
aggregate, hold at least 51% of all issued shares in NSM; and PROVIDED FURTHER
that if the Thai Parties shall transfer any of the shares to a single person or
group of persons acting in concert, (i) such transfer shall be pursuant to a
good faith offer on arms length terms and conditions and be subject to the
rights of the Management Investors under the Shareholders' Agreement (including
the right of first refusal) and (ii) the transferee shall be required to
subscribe to the Shareholders' Agreement and become a party thereto. Before
transferring any shares of NSM pursuant to the preceeding proviso, the
Management Investors, pro rata, shall have the right to purchase such shares at
the same price and on the same terms and conditions offered to the person
referred to above and such offer shall remain outstanding for a certain number
of days. After the first anniversary of the Closing Date, each party to the
Shareholders' Agreement may (a) transfer up to 66% of its shares in NSM during
the period from the first anniversary through the fourth anniversary of the
Closing Date; and (b) transfer up to an additional 9% of its shares in NSM

NSM freely, without regard to any restriction contained in the Shareholders'
Agreement, after the date which is six months following the payment in full of
the Notes. Notwithstanding the foregoing restrictions, any Management Investor
may transfer all or any part of its NSM shares to one or more of its affiliates.
If any Management Investor shall sell shares of NSM in excess of the amounts
indicated above, or cease to hold at least 33% of its original shares, any
agreement to which it is a party may, if so directed by Management Co., will be
terminated by NSM. Notwithstanding the foregoing, SDI shall agree to hold at
least 25% of its original shares, in addition to the shares it acquires through
the exercise of the SDI Warrants, through 2008. In addition, in connection with
any transfer of NSM shares by a party to the Shareholders' Agreement, each party
(other than the transferring party) will have a right of first offer to purchase
its pro rata share of such shares.
 
    The Shareholders' Agreement has a term of 10 years and is governed by the
laws of Thailand. All disputes arising under the Shareholders' Agreement will be
settled by arbitration in Paris, France under the Rules of Conciliation and
Arbitration of the International Chamber of Commerce.
 
AGENCY AGREEMENT
 
    NSM Cayman and NSM (Del) have entered into an agency agreement (the "Agency
Agreement"). Under the Agency Agreement, NSM (Del) acted as the agent of NSM
Cayman in connection with the issuance of the Securities. NSM (Del) agreed to,
from time to time, (i) issue the Securities and undertake subsequent borrowings,
and make payments thereunder, solely as the agent of NSM Cayman; (ii) to
transfer the proceeds of such Securities and subsequent borrowings to NSM
Cayman; and (iii) to receive payments from NSM Cayman or such affiliates and
apply such payments to pay principal and interest when due under the Securities
and subsequent borrowings on behalf of NSM Cayman.
 
    To compensate NSM (Del) for its services in acting as the agent of NSM
Cayman with respect to the issuance of the Notes, NSM Cayman agreed to pay NSM
(Del) a fee equal to U.S.$20,000 per annum for each year in which any of the
Securities have been issued by NSM (Del) or in which year any of the Securities
remain outstanding.
 
    Each of NSM Cayman and NSM (Del) agreed not to treat the Securities and
subsequent borrowings as obligations of NSM (Del) for United States federal,
state and local income tax purposes.
 
SDI LICENSE AGREEMENT
 
    NSM and SDI, entered into a 10-year reciprocal license and technology
sharing agreement, through which they will have access to and the right to use
the other party's flat-rolled and, subject to the consent of an exclusive
licensee of the DRI process, DRI production, operation and product technology.
The consent
 
                                       81

of the exclusive licensee has not been obtained and there can be no assurance
that such consent will be obtained. In entering into the SDI License Agreement,
NSM expects to maximize the development and advancement of certain operating
procedures to enhance the development of new high-quality flat-rolled steel
products.
 
    In return for entering into the SDI License Agreement, SDI received
74,468,090 Ordinary Shares and the SDI Warrants which contain exercise
provisions that protect SDI from dilution of its equity interest in NSM in the
event holders of Warrants exercise such Warrants. SDI will be reimbursed for the
exercise price of the SDI Warrants as it exercises the SDI Warrants. SDI will be
responsible for all U.S. taxes on any amounts payable or shares issuable under
the SDI License Agreement.
 
OFF-TAKE AGREEMENTS
 
    NSM has entered into separate, but substantially identical eight year
Off-Take Agreements with Klockner and Preussag for the purchase and resale of
products from the NSM Mill. Under the Off-Take Agreements, Preussag and Klockner
will be obligated to purchase, in aggregate, 100% of NSM's production in 1998
through 2002, and 25% of the Company's production in the years 2001 through
2005. NSM may, at is option, reduce the percentage of its production sold under
the Off-Take Agreements to as little as 67% in 1998, 50% in 1999 and 25% in
2000, if the Company believes it could maximize sales revenues through sales to
other customers. Under the Indentures, sales by NSM to customers other than
Preussag and Klockner, to the extent that the aggregate of such sales results in
receivables outstanding in excess of U.S.$10 million, must be supported by
letters of credit if the customer does not have an investment grade credit
rating.
 
    All sales to Preussag, Klockner and substantially all other export sales
will be U.S.$ denominated.
 
    Under the Off-Take Agreements, NSM must deliver products which are of the
quantity, quality and description required; the products must be fit for the
purposes for which the goods of the same description would ordinarily be used;
and goods will not comply with an individual order if they are not fit for any
particular purpose expressly or implied made known to NSM in writing at the time
the order was placed. If a product purchased under the Off-Take Agreements fails
to meet the requirements of the order, the purchaser shall notify NSM of the
defect in writing. The purchaser may require NSM to take the product back and
deliver substitute products or require NSM to remedy the lack of conformity by
repair, unless this is unreasonable with respect to all circumstances. NSM will
reimburse the purchaser's reasonable inspection costs. If NSM fails to deliver
substitute products or repair the defective products within a reasonable period
of time despite the purchaser's request, the purchaser may remedy the lack of
conformity on its own or have it remedied by third parties at NSM's cost. This
also applies if NSM's remedies are not satisfactory. Alternatively, the
purchaser may reduce the price in the same proportion as the value that the
goods actually delivered had at the time of the delivery bears to the value that
conforming goods would have had at that time. The purchaser may forsake these
remedies and declare the order void in case of non-delivery or late delivery.
 
EMPLOYMENT AGREEMENT
 
    Upon the consummation of the Offering, the Company and Mr. John W. Schultes,
President and CEO of NSM, entered into an eight-year employment agreement (the
"New Employment Agreement"). Under the New Employment Agreement, Mr. Schultes
will receive a base salary of U.S.$240,000 per annum with increases of 5% per
annum (calculated on a cumulative, compounded basis) during the term of the New
Employment Agreement. At the discretion of Management Co., Mr. Schultes will
also be eligible for an annual bonus based on the Company's return on equity,
profitability, operating efficiency and adherence to capital expenditure budgets
and construction timetables. It is also the Company's intention, based on
Management Co.'s decision to institute a share option plan within twelve months
of the Offerings, to grant Mr. Schultes options to acquire shares in NSM in an
amount such that upon the expiration of the term of
 
                                       82

his employment such options can reasonably be expected to produce a U.S.$2
million gain; PROVIDED, HOWEVER, that the financial results set forth in the
Projection are substantially achieved. The New Employment Agreement will contain
provisions limiting Mr. Schultes' ability to compete against NSM should he no
longer be employed by the Company. Under these provisions, Mr. Schultes will be
restricted in his activities with regard to DRI throughout the world and with
regard to flat-rolled steel production in the countries that currently make up
the ASEAN [Update].
 
COAL SUPPLY AGREEMENT
 
    The Company and SSM have entered into a 10 year contract for the supply of
Vietnamese anthracite coal. This agreement went into effect on April 1, 1997 and
requires the Company to purchase a fixed amount of coal in each of the 10
contract years. By mutual consent, the parties have agreed to delay the start of
deliveries under this contract. The Company retains the option to purchase an
additional set amount in each contract year. The amounts of coal to be purchased
vary over the life of the contract. SSM is penalized if the coal it delivers
fails to meet certain quality standards.
 
    Prices for the coal are set through negotiation between the parties before
the beginning of each contract year. Prices are set in U.S.$ and include
delivery to Sriracha Harbor. Payment is at sight by means of an irrevocable
letter of credit. The Company is separately responsible for demurrage, unloading
and delay. Risk of loss passes from SSM to the Company when the goods are loaded
onto the ship, while ownership passes from SSM upon full payment of all money
due. The agreement is governed by the laws of England and subject to
jurisdiction in the first instance by a competent court in Rotterdam, The
Netherlands.
 
IRON ORE FINES SUPPLY AGREEMENT
 
    The Company has entered into a five-year contract with MMTC for the supply
of iron ore fines. The Agreement went into effect on February 6, 1997. Price and
tonnage for each contract year is determined through negotiations between the
parties at the start of each year. The price is subject to bonuses and penalties
depending on the quality of the iron ore fines supplied. Payment is in U.S.$ by
a commercial letter of credit. Alternatively, the Company may wire transfer 100%
of the sale value in advance.
 
    Vessels to carry ore under the contract will be chartered by the Company or
MMTC depending on competitiveness. The Company assumes risk of loss once the ore
is loaded onto the vessel and has responsibility for insurance as of that time.
MMTC relinquishes title when it receives reimbursement. The contract is subject
to an arbitration clause where the arbitrator is appointed in accordance with
the provisions of the Rules of Conciliation and Arbitration of the International
Chamber of Commerce. Venue for the arbitration is Singapore.

eligible for an annual bonus based on the Company's return on equity,
profitability, operating efficiency and adherence to capital expenditure budgets
and construction timetables. It is also the Company's intention, based on
Management Co.'s decision to institute a share option plan within twelve months
of the Offerings, to grant Mr. Schultes options to acquire shares in NSM in
amount such that upon the expiration of the term of his employment such options
can reasonably be expected to produce a U.S.$2 million gain. The New Agreement

terminates the agreement NSM will pay one year of salary. An annual review of
performance and compensation will be conducted. Additionally, NSM agrees to
provide a car and a driver for business use and certain other benefits to Mr.

payment of Baht 500,000 will be made for 3 years (12 payments) to reimburse Mr.
Hosick for the loss in his USX pension as a result of accepting an early
retirement. Additionally, NSM agrees to provide a car and a driver for business
use and certain other benefits to Mr. Hosick and his wife. This employment
agreement runs until September 15, 2001. Each party will provide the other with
at least 6 months prior written notice of termination.
 
EMPLOYEE COMPENSATION
 
    NSM has established certain incentive compensation programs for its
employees that are designed to encourage productivity by paying bonuses to
groups of employees, based on various measures of productivity. These programs
are patterned after incentive programs in place at SDI. The programs are
designed to reward employees for productivity, quality and efficiency efforts.
It is not unusual for a significant amount of an employee's total compensation
to consist of such bonuses.
 
    Productivity is measured by focusing on groups of employees and not
individual performance. Three groups of employees participate in the bonus
program: production, administrative and department managers. Each group of
employees has its own bonus program or programs.
 
    Production employees, consisting of those directly involved in the melting,
casting and rolling processes, are eligible to participate in two cash bonus
programs: the production bonus and the profit sharing bonus. The production
bonus, if any, is based upon the quantity of quality product produced each week.
The amount of the production bonus is determined for and allocated to each shift
of employees. Depending upon the amount of quality product produced, the bonus
may be equal to or greater than the base hourly wage paid to an employee. A
profit sharing bonus is determined and paid to production employees on an annual
basis based on the Company's profits.
 
    NSM has also established a cash bonus plan for administrative employees,
including accountants, engineers, secretaries, accounting clerks and
receptionists. Bonuses under the plan are based upon the Company's return on
assets and on Company profitability.
 
    NSM's managerial employees are compensated based on return on assets and
profit sharing.
 
    Additionally, the Company will invest a portion of its yearly profits in a
Company sponsored employee savings plan. These programs are intended to
encourage employees to be efficient in the performance of their jobs and to
assist the Company in developing and retaining a loyal, enthusiastic workforce.

                           RELATED PARTY TRANSACTIONS
 
    NO DIRECTOR, OFFICER, PRINCIPAL SHAREHOLDER OR OTHER INSIDER, OR ANY
ASSOCIATE OR AFFILIATE OF SUCH PERSONS HAS OR HAD ANY MATERIAL INTEREST, DIRECT
OR INDIRECT, IN ANY TRANSACTION OR PROPOSED TRANSACTION THAT HAS MATERIALLY
AFFECTED OR WILL MATERIALLY AFFECT THE COMPANY, EXCEPT AS OTHERWISE DISCLOSED
HEREIN AND EXCEPT AS DESCRIBED BELOW:
 
DESCRIPTION OF TRANSACTIONS INVOLVING NSM AND ITS AFFILIATES
 
    The Company engaged in a series of related party transactions in which it
used money deposited at various Thai financial institutions to set-off the debts
owed by affiliated companies to those same financial institutions. These
transactions are described below. The Company's deposits were in the form of
purchases of promissory notes issued by the financial institutions. The Company
pledged, and/or transferred its right to receive deposits on, the promissory
notes back to the financial institutions to secure the debts of the affiliated
companies. Later, the Company agreed to allow the financial institutions to
set-off the promissory notes against the debts of the affiliated companies.
These transactions resulted in the financial institutions taking the money NSM
had on deposit and NSM accepting the obligations of its affiliated companies.
The activities of these finance companies were suspended in June and August of
1997 by order of the Ministry of Finance and closed down on December 8, 1997.
This order was not directed at these specific transactions, but rather reflected
macro-economic issues in Thailand. The Ministry of Finance ordered that all
promissory notes issued by these finance companies would have to be exchanged
for obligations of Krung Thai Bank Public Company Limited or Krung Thai Thanakit
Finance and Securities Public Company Limited. Furthermore, the Ministry of
Finance ordered that repayment on promissory notes of the finance companies of
over 10 million Baht would be delayed for five years.
 
    Rather than continue to hold illiquid and the potentially uncollectible
promissory notes, in a series of transactions starting in September 1997, the
Company has to date transferred, pledged or secured amounts under these
promissory notes for the benefit of certain affiliates of the company including:
NTS which operates a nearby steel rebar manufacturer plant; Trakkapol Company
Limited ("Trak"); Nakornthai Integrated Steel Company Limited, ("NIS") and Metal
Star Company Limited ("Metal Star") which operate steel re-rolling and
processing plants (Trak, NIS and Metal Star are collectively referred to herein
as the "Affiliates"). NTS has used these promissory notes to set-off loans it
owes to various finance companies. In turn, NTS has agreed to repay NSM for the
value of the set-off, plus interest within 3 years. A finance company owed money
by the Affilates is similarly attempting to set-off their debts. NSM is
challenging the ability of this finance company to set-off the Affiliates' debts
against promissory notes owned by NSM.
 
    The transaction between NSM and NTS was approved by the Extraordinary
Meeting of NSM Shareholders No. 1/2450 held on October 22, 1997. As a result:
(a) the obligation of NTS to NSM is payable prior to the five year maturity of
the finance company promissory notes, (b) NSM has the ability to negotiate with
NTS regarding repayment, whereas repayment from the closed finance companies is
subject to the government liquidation of those finance companies, and (c) NTS
has the ability to pay interest and principal to NSM through cash, steel
deliveries and water deliveries from NTS's reservoir. NSM intends to exchange
the promissory notes issued by the Affiliates' creditor for obligations of Krung
Thai Bank Public Company Limited.
 
    The status of these transactions is unclear due to the December 8, 1997
closure of these financial institutions by the Ministry of Finance. See "Annex
A--Kingdom of Thailand." Under the Audited Financial Statements of the Company,
these obligations of affiliated companies have been fully reserved as
uncollectible debts. Although the Company does not expect to recover on these
obligations, it reserves its right to do so in the future.
 
    The Company used approximately 535,518,313 Baht worth of promissory notes in
a series of related party transactions. On December 27, 1996, the Company
purchased a promissory note from Thai Financial
 
                                       91

Trust Public Company Limited ("TFT") in the amount of 60,000,000 Baht. On March
26, 1997, the Company purchased a promissory note in the amount of 150,000,000
Baht from the Pacific Finance & Securities Public Company Limited ("Pacific").
This note was due on June 26, 1997 and was replaced on December 1, 1997 with
another 150,000,000 Baht promissory note. On August 8, 1996, the Company
purchased a promissory note worth 190,000,000 Baht from the Cathay Finance &
Securities Public Company Limited ("Cathay"). On September 26, 1996, NSM
purchased two promissory notes from the Finance One Public Company Limited worth
an aggregate of 100,000,000 Baht ("Fin-One"). Additionally, the Company owns
three promissory notes in the amount of 224,008,706.83 Baht issued by the Thai
Rung Reung Finance & Securities Company Limited ("Thai Rung").
 
    The Company used the principal amount and interest on the promissory notes
of TFT, Cathay and Fin-One Pacific to set-off debts owed by NTS. In Letters of
Consent dated November 19, 1997, NSM agreed to use the TFT promissory notes to
set-off debts owed by NTS to TFT. Including interest, this set-off was valued at
67,158,920.54 Baht. On March 26, 1997, NSM agreed to use the promissory note
issued by Pacific to secure the debts of NTS. Including interest, this set-off
was valued at $161,468,568 Baht. On August 8, 1996, NSM pledged its Cathay
promissory notes as security for the debts owed by NTS to Cathay. On October 29,
1997, NSM issued a letter to Cathay stating its intention to use the Cathay
promissory notes to repay the debts owed by NTS to Cathay. Including interest,
this set-off was valued at 201,161,029.45 Baht. On September 26, 1996, NSM
pledged its Fin-One promissory notes as security for the debts owed by NTS to
Fin-One. NSM also entered into a separate Pledge Agreement on the same day. This
Pledge Agreement made NSM liable for the full amount of debts owed by NTS to
Fin-One. However, this agreement was superseded by a Letter of Consent dated
November 13, 1997 under which NSM agreed to use its Fin-One promissory notes to
set-off the debt owed by NTS to Fin-One. Including interest, this set-off was
valued at 105,729,794.50. NSM is no longer liable for the full debt owed by NTS
to Fin-One.
 
    Excluding interest, NTS had debts of approximately: 260,000,000 Baht to TFT;
163,000,000 Baht to Pacific; 190,000,000 Baht to Cathay; and 100,000,000 Baht to
Fin-One.
 
    NSM agreed to use its promissory notes to set-off 500,000,000 Baht worth
(excluding interest) of NTS's debt. So far, NSM has set-off approximately
535,518,313 Baht worth of NTS's debts including accrued interest. NTS agreed to
repay NSM for the value of the set-offs within 3 years at an interest rate of
14.8% per annum. The loan may be repaid in a combination of cash, steel
deliveries to NSM and/or NSM's use of water from NTS's reservoir. The Company
may extend the repayment period of the loan. These transactions were approved by
the NSM Extraordinary Meeting of NSM Shareholders No. 1/2540 held on October 22,
1997.
 
    Without giving effect to the Transactions, NTS owns 31.31% of the Company's
total issued shares. Mr. Sawasdi Horrungruang, the Chairman of the Board of
Directors of NSM, owns 15.44% of NTS and is Chairman of the Executive Board of
Directors of NTS. Ms. Siriporn Horrungruang, a sister of Mr. Sawasdi
Horrungruang, owns 8.16% of NTS. Mr. Sawasdi Horrungruang is executor of the
estate of his late brother, Mr. Sawai Horrungruang, which owns 7.46% of NTS.
Additionally, Mr. Sawasdi Horrungruang, Ms. Raveewan Peyayopanakul, Mr. Sunthorn
Chailaemluk, Mr. Chamni Janchai and Ms. Pattama Horrungruang were members of
both the NSM and NTS boards of directors at the time of the transactions
described above.
 
    On March 10, 1997, NSM agreed to use two promissory notes worth, in
aggregate, 210,572,125.78 Baht, from Thai Rung, to secure the obligations of the
following debtors: Trak, NIS and Metal Star. Metal Star and NIS are affiliated
companies of NSM. NSM agreed to secure the debts owed by Trak, NIS and Metal
Star in the amount of 60,000,000 Baht, 70,000,000 Baht and 70,000,000 Baht,
respectively. On October 17, 1997, Thai Rung informed NSM that it would exercise
its rights to set-off these debts because the debtors were in default. Thai Rung
consolidated NSM's promissory notes into one note on October 17, 1997. On
October 28, 1997, NSM requested that this option be delayed until NSM
shareholders resolutions concerning the set-offs were passed. The NSM
shareholders did not approve the Thai Rung set-off. Thai
 
                                       92

Rung subsequently verbally informed NSM that the set-off had already been made.
NSM is considering its options in this matter. It is likely that the outcome of
this transaction will be determined by the FRA.
 
    The Company also made a loan to Metal Star in January 1997 for the amount of
approximately 350,000,000 Baht. This loan matured on December 31, 1997. The rate
of interest on the loan to Metal Star is 16% per annum. This transaction was
approved and ratified by the Extraordinary Meeting of Shareholders No. 1/2540
held on October 22, 1997.
 
    The estate of Mr. Sawai Horrungruang owns 25% of NIS. Mr. Sawai Horrungruang
was a brother of Mr. Sawasdi Horrungruang. Mr. Sawasdi Horrungruang is an
executor of Mr. Sawai Horrungruang's estate. Mr. Sunthorn Chailamlak, a director
of NSM, NTS and Metal Star, owns 25% of NIS. Mr. Sawasdi Horrungruang owns 20%
of NIS. Mr. Sakda Horrungruang, a brother of Mr. Sawasdi Horrungruang, owns 5%
of NIS.
 
    Mr. Sunthorn Chailaemlak, a director of NSM and NTS, owns 30% of Metal Star.
Mr. Sakda Horrungruang, a brother of Mr. Sawasdi Horrungruang, owns 30% of Metal
Star. Mr. Suraphol Jirabut, a brother-in-law of Mr. Sawasdi Horrungruang, owns
19.6% of Metal Star. Mr. Chaiyapol Horrungruang, a nephew of Mr. Sawasdi
Horrungruang owns 8% of Metal Star. Ms. Nuchanart Horrungruang, a niece of Mr.
Sawasdi Horrungruang, owns 6% of Metal Star. Mr. Pravit Horrungruang, a nephew
of Mr. Sawasdi Horrungruang, owns 6% of Metal Star.
 
    The only connection between NSM and Trak is that the wife of one of Mr.
Sawasdi Horrungruang's nephews, Mrs. Siriwan Horrungruang, is on the Trak board
of directors. Thai Rung requested that NSM guarantee Trak's debts. NSM agreed to
guarantee Trak's debts as it did not want to jeopardize its ongoing relationship
with Thai Rung.
 
    The Company has entered into a commercial assistance agreement with Mr.
Reuben L. Perin. Under the terms of the agreement, Mr. Perin will be paid
U.S.$6,000 per month plus expenses. Mr. Perin will spend at least four days each
month assisting the Company in all aspects of sales, marketing and international
trade issues. Mr. Perin has been named a director of NSM.
 
    In addition, Mr. Sawasdi Horrungruang and Mr. Chamni Janchai provided
personal guarantees for interim financing from First-Bangkok City Bank to NSM.
The Company used proceeds from the Offerings to repay the lenders of these loans
and the lenders have released the guarantees provided by Mr. Horrungruang and
Mr. Janchai. The amount of the financing is approximately 400 million Baht. See
"Description of Certain Indebtedness--Interim Financing."
 
DESCRIPTION OF OTHER TRANSACTIONS
 
    The Company entered into a credit agreement with the Industrial Finance
Corporation of Thailand ("IFCT") for financing in the amount of U.S.$10 million.
Under the agreement, Mr. Sawasdi Horrungruang and Mr. Chamni Janchai provided
personal guarantees for the credit to NSM. NSM used a portion of the proceeds of
the Offerings and Debenture Offering to repay money under the IFCT financing.
The IFCT released Mr. Horrungruang and Mr. Janchai from their liabilities under
their guarantees.
 
    NSM has entered into various agreements with SDI, Enron, and McDonald. SDI
is a Management Investor and received 10% of the outstanding shares on a fully
diluted basis of the Company in return for licensing certain rights to NSM
pursuant to the SDI Agreement. SDI received this percentage through a
combination of Ordinary Shares and the SDI Warrants. The exercise price of the
SDI Warrants will be reimbursed by the Company upon the exercise of the SDI
Warrants. Enron acquired 16,086,844 Ordinary Shares from the Company as part of
the Management Equity Investment and 10,911,382 as part of the offering and sale
of the Private Placement Shares. In addition, Enron acquired 24,918,656 Ordinary
Shares and McDonald acquired 20,084,344 Ordinary Shares, in a privately
negotiated transaction in the secondary market for Ordinary Shares. The sellers
included relatives of Mr. Sawasdi Horrungruang, the Chairman of NSM. Enron has
agreed to work with NSM to obtain all funds (in addition to the U.S.$20 million
 
                                       93

subordinated financing it has committed to date) necessary to complete
construction of the Co-Gen Facility. ECT Securities Corp., an affiliate of
Enron, is a co-manager of the Offering. McDonald is a Management Investor and is
providing investment banking services to NSM. McDonald is also a co-manager of
the Offerings.
 
    In addition to related party transactions involving NSM, SDI, Enron,

to SDI. In satisfaction of fees due for advisory and underwriting services
provided to the Company, McDonald received approximately U.S.$18 million from
the proceeds of the Transactions.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
    The following is a brief description of the basic terms of the Company's
Bank Credit Facility and other Indebtedness. The following discussion does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to the instruments governing the indebtedness.
 
THE BANK CREDIT FACILITY
 
    The Bank Credit Facility provides for (i) a U.S.$308 million term loan
facility (the "U.S.$ Facility") and (ii) a 3.3 billion Baht term loan facility
(the "Baht Facility") (collectively, the "Facilities"). As of December 8, 1997,
U.S.$1.186 million is held as a reserve in case the Deutsche Mark appreciates
compared to the U.S.$.
 
    Interest under the Bank Credit Facility is payable quarterly, on March 1,
June 1, September 1, and December 1 of each year, in arrears at the rate of
either LIBOR plus 2.5 percent per annum or SIBOR plus 2.5 percent per annum for
the U.S.$ Facility and the lower of MLR (Minimum Lender Rate) plus one-half
(0.5) percent per annum or MRR (Minimum Retail Rate) for the Baht Facility.
Payments of principal under the Bank Credit Facility are to be made in 12
semi-annual installments and, in any event, the last repayment shall be made
before the maturity of the Notes and Debentures. Thus, the 12th installment will
be made on the same day as the 11th installment. The first principal repayment
shall be made on the interest payment date which falls four years from the first
drawdown or two years from the commencement of commercial operations of the Hot
Mill, whichever is earlier. The Company used U.S.$50 million from the proceeds
of the Offerings to prepay a portion of the Facilities and U.S.$17 million of
accrued interest payable. Each of the Thai lenders was entitled to prepayment in
accordance with the proportion of (a) loans already advanced by it to the
Company under the Bank Credit Facility and still outstanding to (b) the
aggregate loans already advanced by the Thai lenders to the Company under the
Bank Credit Facility. In connection with any lender who extends the Facilities,
the prepayment shall be used (i) first to settle loans outstanding under the
Baht Facility advanced by such lender and (ii) second, if there is any sum
remaining, to settle loans outstanding under the U.S.$ Facility advanced by such
lender.
 
    On the Issue Date and upon receipt of the prepayment amount plus past due
interest, the Lenders under the Bank Credit Facility released the mortgages and
other security interests on the collateral thereunder and, pursuant to the Bank
Credit Facility and the Security Sharing Agreement, now share equally and
ratably in the Collateral (other than the Offshore Reserve Account and the Notes
DSR Account) with the holders of the Senior Notes and the Senior Subordinated
Notes. See "Security Arrangements--Security Sharing Agreement".
 
    The Lenders also agreed that the holders of the Debentures will share in the
Collateral on a second priority basis.
 
    Pursuant to the Bank Credit Facility, the Company has agreed that, other
than in connection with the enforcement of the security interests granted in the
Collateral, in the event there are insufficient funds available at any time to
make all payments of principal or interest then due under the Bank Credit
Facility and the Notes and the Debentures, the Company will pay 100% of any
interest and 50% of any principal then due under the Bank Credit Facility prior
to paying any interest then due on the Notes and the Debentures. In exchange for
this agreement, the lenders under the Bank Credit Facility have agreed, in such
case that failure to pay the additional 50% (or part thereof) of any scheduled
principal payment due to such lenders will not be a default under the Bank
Credit Facility, and such amount will be paid out pro rata over the then
remaining scheduled principal payments under the Bank Credit Facility. The Bank
Credit Facility also provides that the Company will repay additional principal
each year in an amount equal to 50% of the Company's EBITDA for the immediately
preceeding fiscal year after deducting interest expense, principal payments,
taxation and maintenance capital expenditures, commencing from a fiscal year
after December 31, 1999. For purposes of this provision, "EBITDA" is defined as
earnings before interest expense, taxation, depreciation and amortization.
 
                                       95

    The Bank Credit Facility provides for the waiver by the lenders thereunder
of any events of default in connection therewith occurring prior to the Issue
Date.
 
    The Bank Credit Facility contains certain restrictive covenants which impose
restrictions and/or limitations on the operations and activities of the Company
including, among other things: limitations on the payment of dividends in the
years that the Company's obligations have not been fully paid; limitations on
the amendment of the Company's Memorandum or Articles of Association and the
change of the management of the Company and limitations on the execution of
encumbrances (mortgage or otherwise) on, the Company's real property, machinery
or rights, except those that have been made relating to the Offerings, the
Equity Investments and the Working Capital Facility.
 
WORKING CAPITAL FACILITY
 
    BNP has provided the Company with working capital financing through (i) a
U.S.$150 million offshore revolving receivable discounting facility (the
"Offshore Facility") and (ii) an onshore revolving receivable discounting
facility (the "Onshore Facility" and together with the Offshore Facility, the
"Working Capital Facility") with a U.S.$15 million tranche and a 400 million
Baht tranche. Both the Offshore Facility and the Onshore Facility have final
maturity dates of December 31, 2000.
 
    The Offshore Facility is used to finance offshore receivables generated
through the Company's sales under the Off-Take Agreements. The Onshore Facility
is used to finance domestic sales paid in either Baht or U.S.$.
 
    Advances correspond in amount to accepted receivables, discounted by
reference to LIBOR and the applicable margin. Each advance under the Working
Capital Facility is secured by a guarantee of the underlying receivable from the
relevant offtaker. All amounts payable in respect of such receivables are paid
directly into a collection account maintained with BNP prior to disbursement to
the Revenue Account.
 
    Prior to BNP being obligated to provide funds under the Onshore Facility,
the Company is required to provide evidence that it has requested a Thai bank,
acceptable to BNP, to provide such funding and that such bank declined to do so.
 
    Under the Offshore Facility, BNP will require Preussag's and Klockner's
respective credit quality to meet certain standards in order for receivables
from either of them to qualify as an eligible receivable.
 
    The Working Capital Facility contains certain restrictive covenants which
impose restrictions and/or limitations on the operations and activities of the
Company, including, among other things, compliance with applicable law
limitations on transactions with affiliates, limitations on changes in the
nature of the Company's business, and certain financial reporting requirements.
 
INTERIM FINANCING
 
    The First Bangkok City Bank provided the Company interim financing in the
form of a letter of credit, a trust receipt, a guaranty and an acceptance or an
aval of notes, in both Thai Baht and foreign currency for the amount of
approximately 400 million Baht (based upon the exchange rate as of October 11,
1997). The credit was granted to finance the Company's purchase of raw
materials. The Company provided The First Bangkok City Bank and the Industrial
Finance Corporation of Thailand with a second mortgage over the land and
buildings comprising the Mill pursuant to Thailand Ex-Im Credit. The mortgage
amount was 600 million Baht with each institution. On the Issue Date, the First
Bangkok City Bank released the mortgage after the Company arranged to deposit an
amount equal to the outstanding amount of the credit and pledge the same with
The First Bangkok City Bank. The Company has also agreed that The First Bangkok
may deduct, hold or set-off the deposit against the Company's obligations
thereunder without further notice.
 
                                       96

    Mr. Sawasdi Horrungruang and Mr. Chamni Janchai, two directors of the
Company, who had provided personal guarantees for the financing which guarantees
were released on the Issue Date.
 
THAILAND EX-IM CREDIT
 
    The Industrial Finance Corporation of Thailand ("IFCT") granted the
Company's application for financing credit for the amount of U.S.$10 million, in
the form of a packing credit pursuant to an agreement dated as of February 13,
1998. The credit has been granted to finance the Company's import and export
activities. The financing period shall not exceed 180 days from the date of each
letter of credit. The interest rate has not been fixed. The Company provided
IFCT, along with the First Bangkok City Bank a second mortgage over the land and
buildings of the Mill. The mortgage amount is 600 million Baht to each
institution.
 
    On the Issue Date, IFCT released the mortgage after, the Company arranged to
deposit the amount equal to the outstanding amount under each letter of credit
with the IFCT of approximately U.S.$2.5 million, and pledge the same, or a bank
acceptable to IFCT to secure the Company's obligation under the credit.
 
    Mr. Sawasdi Horrungruang and Mr. Chamni Janchai, two directors of the
Company, provided personal guarantees which were released on the Issue Date.
 
    Under the agreement, IFCT had levied the following conditions: (i) the

specification on product size, quality, price, volume and definite delivery;
(ii) the products must meet the specifications in the letters of credit before

to confirm that the quality and size of the products meet with the required
specifications and be accepted by the customer (the issuer of a letter of
credit), and (iv) the Company must comply with the terms and conditions of the

Debentures and the Old Debentures shall be collectively referred to as the
"Debentures." The Senior Notes, the Senior Subordinated Notes and the Debentures
shall be collectively referred to as "Securities." The term "Trustee" shall mean
The Chase Manhattan Bank in its capacity as Senior Notes Trustee, Senior
Subordinated Notes Trustee or Debenture Trustee or all three, as applicable. A
copy of each of the Indentures is available upon request to the Company. The
following is a summary of certain provisions of the Indentures, the Guaranties
and the Securities and does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Indentures
(including the definitions of certain terms therein and those terms made a part
thereof by the Trust Indenture Act of 1939, as amended), the Guaranties and the
Securities. Capitalized terms used herein and not otherwise defined shall have
the meanings assigned to them in the applicable Indenture.
 
    The Securities will be issued only in fully registered form, without
coupons, in denominations of U.S.$1,000 and any integral multiple of U.S.$1,000
(except in the case of the Debentures which are issued in denominations of
US$1). No service charge will be made for any registration of transfer or
exchange of Securities, but the Issuers may require payment of a sum sufficient
to cover any transfer tax or other similar governmental charge payable in
connection therewith. The Securities may be presented for registration of
transfer and exchange at the offices of the registrar, which initially will be
the Trustee. The Issuers may change any paying agent and registrar without
notice to holders of the Securities.
 
    The principal of, premium, if any, interest on and all other amounts payable
under the Notes will be unconditionally guaranteed by the Company as evidenced
by the Guaranties set forth in the applicable Indenture. See "--Guaranties."
 
    The Securities will be represented by one or more registered notes in global
form and in certain circumstances may be represented by notes in definitive
form. See "Description of the Note Depositary Agreement; Delivery and Form." The
Securities will be transferable, exchangeable and subject to replacement at the
offices of the transfer agents.

GUARANTIES
 
    Under the Indentures, the Company will irrevocably and unconditionally
guarantee on, (i) in the case of the Senior Guaranty, a senior basis, (ii) in
the case of the Senior Subordinated Notes, a senior (other than in respect of
any Specified Senior Indebtedness of the Company) basis, (iii) and in the case
of the Debentures a subordinated basis the due and punctual payment of the
principal of, premium, if any, and interest on, and all other amounts payable
under, the Securities when and as the same shall become due and payable, whether
on the relevant maturity date, upon acceleration, by call for redemption, upon
repurchase or purchase pursuant to a Change of Control or Asset Disposition or
otherwise. The Company's obligations under the Guaranties are secured by the
Collateral as described under "Security Arrangements." The Company has (i)
agreed that its obligations under the Guaranties will be as principal obligor
and not merely surety, and will be enforceable irrespective of any invalidity,
irregularity or unenforceability of the Securities or the Indentures and (ii)
waived its right to require the Trustee to pursue or exhaust its legal or
equitable remedies against the Issuers prior to exercising its rights under
either of the Guaranties. Each Indenture provides that the applicable Guaranty
will be governed by, and construed in accordance with, the laws of the State of
New York, which laws would not require the Trustee to pursue or exhaust its
legal and equitable remedies against the Issuers prior to exercising their
rights under such Guaranty. There can be no assurance that a Thai court would
give effect to this provision.
 
    The relevant Guaranty will not be discharged with respect to any Security
except by payment in full (or defeasance) in cash of the principal thereof,
premium, if any, and interest thereon and all other amounts payable thereunder.
Moreover, if at any time any amount paid under a Note is rescinded or must
otherwise be restored, the rights of the holders of the Securities under the
applicable Guaranty will be reinstated with respect to such payment.
 
                                       99

SECURITY
 
    The obligations of the Note Issuers under the Securities will be secured by
pledges of the capital stock of NSM (Del). The obligations of the Company under
the Senior Note Guaranty and the Subordinated Note Guaranty will be secured
equally and ratably by (1) a first mortgage over the land and buildings
comprising the Mill (except for the Co-Gen Facility); (2) a security interest in
all amounts in the Notes DSR Account and Offshore Reserve Account; (3) a
security interest in all machinery and moveable property located at the Mill;
(4) an assignment of all insurance and reinsurance policies maintained by the
Company on the Mill (except for the Co-Gen Facility); (5) an assignment of the
Company's rights and benefits under the Project Documents; (6) a conditional
assignment and general pledge of the Revenue Account, the Notes Sinking Fund
Account and the Operating Account; (7) a pledge of certain Permitted
Investments; (8) a pledge of all issued and outstanding shares of NSM Cayman;
and (9) an assignment of Performance Bonds (all such collateral security, the
"Collateral"). The Collateral (other than the Collateral described in clauses
(2) and (8) above) will also secure, on an equal and ratable basis, certain
existing Indebtedness under the Bank Credit Facility. In addition, all
Collateral will secure, on a second priority basis, the obligations of the
Company in respect of the Debenture Guaranty.
 
    There can be no assurance that the proceeds of any sale of the Collateral
following an Event of Default would be sufficient to satisfy payments due on the
Securities. In addition, a substantial portion of the security arrangements
relating to the Collateral will be governed by Thai law and may be subject to
significant restrictions regarding enforceability. See "Risk Factors--No
Assurance of Adequate Collateral; Shared Collateral; Ability to Realize on
Collateral," "--Enforcement of the Mortgages," "--Book-Entry Interests;
Dependence on Intermediaries," "--Thai Bankruptcy Law," "--Lack of Enforcement
of Foreign Judgments" and "Security Arrangements."
 
CREDIT SUPPORT
 
    NOTES DSR ACCOUNT.  The Note Issuers and the Company on the Issue Date
deposited, in an account (the "Notes DSR Account") maintained with the
Collateral Agent, a portion of the Notes Net Proceeds together with a portion of
the proceeds of the Debenture Offering, equal to the sum of (i) the aggregate
interest to be payable on the Senior Notes on the first three Interest Payment
Dates, (ii) the aggregate interest to be payable on the Senior Subordinated
Notes on the first two Interest Payment Dates and (iii) the aggregate interest
to be payable on the Debentures on the first two interest payment dates. Amounts
on deposit in the Notes DSR Account shall at all times be maintained in U.S.$ at
a Qualifying Financial Institution and may only be invested in Permitted Foreign
Investments. The interest due on the Notes on the first two Interest Payment
Dates after the Issue Date, and the interest due on the Debentures on the first
two interest payment dates in respect of the Debentures shall be paid from
amounts on deposit in the Notes DSR Account. Thereafter, the balance in the
Notes DSR Account shall at all times be at least equal to the aggregate interest
payable on the Senior Notes on the next applicable Interest Payment Date.
Notwithstanding the preceding sentence, the Company shall have the right,
assuming no other Event of Default then exists, to cause amounts held in the
Notes DSR Account to be withdrawn to pay interest on the Securities even though
such withdrawal would reduce the amounts remaining in the Notes DSR Account
below the minimum level indicated above; PROVIDED, HOWEVER, that any withdrawal
that would reduce such amounts below the required level may only be made to the
extent sufficient funds are not then available in the Revenue Account to pay
such interest; PROVIDED FURTHER, HOWEVER, that the minimum required level for
the Notes DSR Account must be replenished in full within 30 days following any
such withdrawal.
 
    OFFSHORE RESERVE ACCOUNT.  The Note Issuers and the Company on the Issue
Date deposited, in an account (the "Offshore Reserve Account") maintained with
the Collateral Agent, the balance (not otherwise deposited in the Notes DSR
Account) of the Note Net Proceeds, together with the balance of the proceeds of
the Debenture Offering and any Equity Investment Proceeds. Amounts on deposit in
the
 
                                      100

Offshore Reserve Account shall at all times be maintained in U.S.$ at a
Qualifying Financial Institution and may only be invested in Permitted Foreign
Investments. The amounts held in the Offshore Reserve Account may be withdrawn
by the Company only to (i) fund Phase II Construction Costs that are required to
be paid by the Company; PROVIDED that amounts may only be withdrawn to fund such
costs payable to vendors domiciled in Thailand to the extent sufficient funds
are not then available in the Operating Account to fund such costs and (ii) fund
Working Capital Requirements to the extent sufficient funds are not then
available in the Revenue Account to fund such requirements; PROVIDED FURTHER
that the Company may only withdraw funds from the Offshore Reserve Account for
the purpose of funding Working Capital Requirements up to a maximum of U.S.$70
million in the aggregate. If the aggregate amount withdrawn from the Offshore
Reserve Account since the Issue Date for Working Capital Requirements exceeds
U.S.$50 million, or if after giving effect to any proposed withdrawal the
aggregate amount withdrawn from the Offshore Reserve Account for Working Capital
Purposes would exceed $50 million, then amounts in excess of such U.S.$50
million may only be withdrawn for such purposes upon a request by the Company
accompanied by a certificate to the Collateral Agent from the Independent
Engineer or another independent engineering firm of suitably similar
international reputation and experience which is reasonably satisfactory to the
Collateral Agent (a "Substitute Independent Engineer") stating that the funds
available to the Company in the Offshore Reserve Account (after giving effect to
the proposed withdrawal) are sufficient to satisfy all of the Company's
remaining required Phase II Construction Costs through Phase II Completion. At
Phase II Completion, any remaining amounts in the Offshore Reserve Account
(except to the extent then required to replenish the Notes DSR Account) may, at
the Company's option demonstrated by a written request to the Collateral Agent,
be applied to (x) tender for a portion of the Securities then outstanding at
100% of Accreted Value or (y) repay principal amounts outstanding under the Bank
Credit Facility; PROVIDED that if the Company achieves Profitable Operations as
of any date prior to and including December 31, 2001, the Company will as of
such date have the further option, demonstrated by a written request to the
Collateral Agent, to apply any amounts then remaining in the Offshore Reserve
Account (except to the extent then required to replenish the Notes DSR Account)
to the payment of Phase III Construction Costs. Notwithstanding the foregoing,
if the Company fails to achieve Profitable Operations prior to December 31,
2001, any remaining amounts in the Offshore Reserve Account must be used by the
Company to tender for the Securities at a price equal to 100% of the Accreted
Value thereof on the date of purchase (a "Stage III Tender"). Any amounts
remaining in the Offshore Reserve Account after a Stage III Tender will be
applied by the Company (x) first to replenish the Notes DSR Account (if
necessary) and (y) second to pay overdue interest, if any, and principal amounts
outstanding under the Bank Credit Facility.
 
    NOTES SINKING FUND ACCOUNT.  The Company shall establish with the Collateral
Agent a sinking fund account (the "Notes Sinking Fund Account") into which the
Company shall deposit, no later than the fifteenth day following the last day of
each fiscal quarter of the Company (based on the Company's fiscal year in effect
on the Issue Date), an amount equal to the Cash Flow Sweep Amount. Amounts on
deposit in the Notes Sinking Fund Account shall at all times be maintained in
U.S.$ at a Qualifying Financial Institution and may only be invested in
Permitted Foreign Investments. The amounts held in the Notes Sinking Fund
Account shall be used to retire Notes at maturity or to satisfy repurchase
obligations in respect of the Notes arising from the offers to repurchase
described under "Repurchase at the Option of Holders--Change of Control,"
"--Sale of Assets and Subsidiary Stock" and "--Offer to Repurchase Upon Failure
to Attain Profitable Operations." Notwithstanding the foregoing, the Note
Issuers or the Company may use amounts held in the Notes Sinking Fund Account
(i) during the period prior to the second anniversary of the Issue Date and
during any period where Profitable Operations have been achieved and are
continuing, to make payments of Phase III Construction Costs, to fund working
capital shortfalls, to invest in or acquire Additional Assets or to purchase,
redeem or otherwise acquire for value Senior Indebtedness of the Company or the
Note Issuers and (ii) at all other times, solely to purchase, redeem or
otherwise acquire for value Notes or to make scheduled principal or interest
payments on Senior Indebtedness of the Company or the Note Issuers.
 
                                      101

    REVENUE ACCOUNT.  The Company shall establish with the Collateral Agent a
revenue account (the "Revenue Account") into which the Company shall deposit
(directly or through an intermediate fund as described below) all sales
proceeds, all insurance proceeds and all other amounts received by the Company
that are not otherwise required to be deposited in the Notes DSR Account or the
Offshore Reserve Account. Subject to any applicable exchange control regulations
in Thailand, proceeds deposited into the Revenue Account in an amount equal to
the sum of (i) the aggregate interest payable on the Notes on the next Interest
Payment Date, (ii) the aggregate interest payable on the Debentures on the next
interest payment date in respect of the Debentures and (iii) any amount required
to be deposited into the Notes Sinking Fund Account applicable to the then
current fiscal quarter, as estimated in advance in good faith by the Company,
shall first accrue, and at all times be maintained, in U.S.$ at a Qualifying
Financial Institution (the "Offshore Sub-account"); PROVIDED, HOWEVER, that,
notwithstanding the foregoing provision, any sales proceeds denominated in Baht
in the ordinary course of the Company's business consistent with past practice
need not be converted into U.S. $ prior to the date such deposited proceeds may
be used to pay U.S.$ denominated obligations or are otherwise deposited into the
Notes Sinking Fund Account. Amounts held in the Offshore Sub-account may be used
by the Company for payments and other uses permitted by the Indentures but,
other than payments of interest on the Securities or deposits into the Notes
Sinking Fund Account, only to the extent all other amounts on deposit in the
Revenue Account are insufficient to make such payments. The Company has obtained
the Bank of Thailand's approval to maintain a portion of export revenue, not to
exceed U.S. $130 million each year, in accounts offshore. The balance of amounts
on deposit in the Revenue Account may be maintained in Baht at a Qualifying
Domestic Financial Institution, which initially shall be the Bangkok Office of
The Chase Manhattan Bank. Amounts on deposit in the Revenue Account (including
the Offshore Sub-account) will be used (i) to fund the Operating Account on the
first day of each month as provided for below, (ii) to fund the Notes Sinking
Fund Account as provided for above, (iii) fund Working Capital Requirements,
(iv) at all times after the first two Interest Payment Dates, to pay interest
when due on the Securities and, if necessary, to fund required amounts in the
Notes DSR Account, with the balance to be invested in Permitted Foreign
Investments, subject to applicable exchange controls and (v) at all times after
the attainment by the Company of Profitable Operations, to fund cash dividends
and distributions that may be made by the Company as provided in "Certain
Covenants--Limitation on Restricted Payments".
 
    OPERATING ACCOUNT.  The Company has established with the Collateral Agent an
operating account (the "Operating Account"), into which the Company shall
deposit on the first day of each calendar month an amount such that, immediately
after giving effect to such deposit, the balance of such account shall be equal
to the sum of (i) the capital expenditures (including Phase II Construction
Costs to be paid by the Company to vendors in Thailand) of the Company during
that calendar month as estimated in advance in good faith by the Company and
(ii) any amount required to be paid during such calendar month in connection
with the Bank Credit Facility. Subject to any applicable exchange control
regulations in Thailand, the Operating Account shall be maintained in U.S.$ at a
Qualifying Domestic Financial Institution, which initially shall be the Bangkok
Office of The Chase Manhattan Bank, with funds able to be maintained in Baht to
the extent such funds were maintained in Baht in the Revenue Account and with
funds converted to Baht on an as-needed or as-required basis only.
 
RANKING
 
    SENIOR NOTES AND SENIOR GUARANTY
 
    The indebtedness evidenced by the Senior Notes and the Senior Guaranty will
be senior secured obligations of the Note Issuers and the Company, as the case
may be, will rank pari passu in right of payment with all existing and future
Senior Indebtedness and will be senior in right of payment to the Senior
Subordinated Notes and all existing and future Subordinated Indebtedness
(including the Debentures) of the Note Issuers and the Company.
 
                                      102

    SENIOR SUBORDINATED NOTES AND SENIOR SUBORDINATED GUARANTY
 
    The indebtedness evidenced by the Senior Subordinated Notes and the Senior
Subordinated Guaranty will be senior secured obligations of the Note Issuers and
the Company, as the case may be, but the payment of principal of, premium,
interest and Additional Amounts, if any, on the Senior Subordinated Notes and
the Senior Subordinated Guaranty will be subordinate in right of payment to the
prior payment in full of all Specified Senior Indebtedness of the Note Issuers
and the Company, as the case may be. The Senior Subordinated Notes and Senior
Subordinated Guaranty will rank pari passu with all other Senior Indebtedness of
the Note Issuers and the Company, as the case may be, and senior in right of
payment to all existing and future subordinated indebtedness of the Notes
Issuers and the Company, including the Debentures. Only Indebtedness of the
Issuers or the Company that is Specified Senior Indebtedness will rank senior to
the Senior Subordinated Notes or the Senior Subordinated Guaranty, as the case
may be, in accordance with the provisions of the Senior Subordinated Note
Indenture.
 
    The Note Issuers may not pay principal of, premium or Additional Amounts (if
any) or interest on, the Senior Subordinated Notes or make any deposit pursuant
to the provisions described under "-- Defeasance" below and may not purchase,
redeem or otherwise retire any Senior Subordinated Notes (collectively, "pay the
Senior Subordinated Notes") if (i) any Specified Senior Indebtedness of the Note
Issuers is not paid when due or (ii) any other default on Specified Senior
Indebtedness of the Note Issuers occurs and the maturity of such Specified
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, the default has been cured or waived and any such acceleration has
been rescinded or such Specified Senior Indebtedness has been paid in full.
However, the Note Issuers may pay the Senior Subordinated Notes without regard
to the foregoing if the Note Issuers and the Senior Subordinated Note Trustee
receive written notice approving such payment from the Representative of the
holders of the Specified Senior Indebtedness with respect to which either of the
events set forth in clause (i) or (ii) of the immediately preceding sentence has
occurred and is continuing.
 
    In addition, during the continuance of any default (other than a default
described in clause (i) or (ii) of the first sentence of the immediately
preceding paragraph) with respect to any Specified Senior Indebtedness of the
Note Issuers pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to
effect such acceleration) or the expiration of any applicable grace periods, the
Note Issuers may not pay the Senior Subordinated Notes for a period (a "Payment
Blockage Period") commencing upon the receipt by the Senior Subordinated Note
Trustee (with a copy to the Note Issuers) of written notice (a "Blockage
Notice") of such default from the Representative of the holders of such
Specified Senior Indebtedness specifying an election to effect a Payment
Blockage Period and ending 179 days thereafter (or earlier if such Payment
Blockage Period is terminated (i) by written notice to the Senior Subordinated
Note Trustee and the Note Issuers from the Person or Persons who gave such
Blockage Notice, (ii) because the default giving rise to such Blockage Notice is
no longer continuing or (iii) because such Specified Senior Indebtedness has
been repaid in full).
 
    Notwithstanding the provisions described in the immediately preceding
paragraph, unless the holders of such Specified Senior Indebtedness or the
Representative of such holders have accelerated the maturity of such Specified
Senior Indebtedness, the Note Issuers may resume payments on the Senior
Subordinated Notes after the end of such Payment Blockage Period, including any
missed payments. Not more than one Blockage Notice may be given in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Specified Senior Indebtedness of the Note Issuers during such period.
 
    Upon any payment or distribution of the assets of the Note Issuers upon a
total or partial liquidation or dissolution or reorganization of or similar
proceeding relating to any of the Note Issuers or the property thereof, the
holders of Specified Senior Indebtedness of the Note Issuers will be entitled to
receive payment in full of such Specified Senior Indebtedness before the holders
of Senior Subordinated Notes are entitled to receive any payment and until such
Specified Senior Indebtedness is paid in full, any payment or distribution to
which holders of Senior Subordinated Notes would be entitled but for the
subordination provisions of the Senior Subordinated Note Indenture will be made
to holders of such Specified Senior
 
                                      103

Indebtedness as their interest may appear. If a distribution is made to holders
of Senior Subordinated Notes that due to the subordination provisions should not
have been made to them, such Noteholders are required to hold it in trust for
the holders of Specified Senior Indebtedness of the Note Issuers and pay it over
to them as their interest may appear.
 
    If payment of the Senior Subordinated Notes is accelerated because of an
Event of Default, the Note Issuers or the Company or the Senior Subordinated
Note Trustee shall promptly notify the holders of the Specified Senior
Indebtedness or the Representative of such holders of the acceleration. None of
the Note Issuers and the Company may pay the Senior Subordinated Notes until
five Business Days after such holders or the Representative of the holders of
Specified Senior Indebtedness of the Note Issuers receive notice of such
acceleration and, thereafter, may pay the Senior Subordinated Notes only if the
subordination provisions of the Senior Subordinated Note Indenture otherwise
permit payment at that time.
 
    The obligations of the Company under the Senior Subordinated Guaranty are
subordinated to Specified Senior Indebtedness of the Company. The terms of the
subordination provisions described above with respect to the Note Issuers'
obligations under the Senior Subordinated Notes apply equally to the Company and
the obligations of the Company under the Senior Subordinated Guaranty.
 
    By reason of such subordination provisions contained in the Senior
Subordinated Note Indenture, in the event of insolvency, creditors of the Note
Issuers or the Company who are holders of Specified Senior Indebtedness of the
Issuers or the Company, as the case may be, may recover more, ratably, than the
holders of Senior Subordinated Notes, and creditors of the Note Issuers or the
Company who are not holders of Specified Senior Indebtedness of the Note Issuers
or the Company, as the case may be, may recover less, ratably, than holders of
Specified Senior Indebtedness and may recover more, ratably, than the holders of
the Senior Subordinated Notes.
 
    Pursuant to the terms of the Bank Credit Facility, the Company has agreed
that, other than as a result of enforcement of the security interests granted in
the Collateral, in the event that there are insufficient funds available at any
time to make all payments of principal or interest then due under the Bank
Credit Facility, the Notes and the Debentures, it will pay 100% of any interest
and 50% of any principal then due under the Bank Credit Facility prior to paying
any interest then due on the Notes and the Debentures.
 
    DEBENTURE AND DEBENTURE GUARANTY
 
    The indebtedness evidenced by the Debentures and the Debenture Guaranty will
be subordinated secured obligations of the Note Issuers and the Company, as the
case may be, but the payment of principal of, premium, interest and Additional
Amounts, if any, on the Debentures and the Debenture Guaranty will be
subordinate in right of payment to the prior payment in full of all Debenture
Specified Senior Indebtedness of the Note Issuers and the Company, as the case
may be. The Debentures and Debenture Guaranty will rank senior in right of
payment to all existing and future subordinated indebtedness of the Notes
Issuers and the Company. Only Indebtedness of the Issuers or the Company that is
Debenture Specified Senior Indebtedness will rank senior to the Debentures or
the Debenture Guaranty, as the case may be, in accordance with the provisions of
the Debenture Indenture.
 
    The Issuers may not pay principal of, premium or Additional Amounts (if any)
or interest on, the Debentures or make any deposit pursuant to the provisions
described under "--Defeasance" below and may not purchase, redeem or otherwise
retire any Debentures (collecdtively, "pay the Debentures") if (i) any Debenture
Specified Senior Indebtedness of the Issuers is not paid when due or (ii) any
other default on Debenture Specified Senior Indebtedness of the Issuers occurs
and the maturity of such Debentures Specified Senior Indebtedness is accelerated
in accordance with its terms unless, in either case, the default has been cured
or waived and any such acceleration has been rescinded or such Debenture
Specified Senior Indebtedness has been paid in full. However, the Issuers may
pay the Debentures without regard to the foregoing if the Issuers and the
Debenture Trustee receive written notice approving such payment from the
Representative of the holders of the Debenture Specified Senior Indebtedness
with
 
                                      104

respect to which either of the events set forth in clause (i) or (ii) of the
immediately preceding sentence has occurred and is continuing.
 
    In addition, during the continuance of any default (other than a default
described in clause (i) or (ii) of the first sentence of the immediately
preceding paragraph) with respect to any Debenture Specified Senior Indebtedness
of the Issuers pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to
effect such acceleration) or the expiration of any applicable grace periods, the
Issuers may not pay the Debentures for a period ("Debenture Payment Blockage
Period") commencing upon the receipt by the Debenture Trustee (with a copy to
the Issuers) of written notice (a "Debenture Blockage Notice") of such default
from the Representative of the holder of such Debenture Specified Senior
Indebtedness specifying an election to effect a Debenture Payment Blockage
Period and ending 179 days thereafter (or earlier if such Debenture Payment
Blockage Period in terminated (i) by written notice to the Debenture Trustee and
the Issuers from the Person or Persons who gave such Debenture Blockage Notice,
(ii) because the default giving rise to such Debenture Blockage Notice is no
longer continuing or (iii) because such Debenture Specified Senior Indebtedness
has been repaid in full).
 
    Notwithstanding the provisions described in the immediately preceding
paragraph, unless the holders of such Debenture Specified Senior Indebtedness or
the Representative of such holders have accelerated the maturity of such
Debenture Specified Senior Indebtedness, the Issuers may resume payments on the
Debentures after the end of such Debenture Payment Blockage Period, including
any missed payments. Not more than one Debenture Blockage Notice may be give in
any consecutive 360-day period, irrespective of the number of defaults with
respect to Debenture Specified Senior Indebtedness of the Issuers during such
period.
 
    Upon any payment or distribution of the assets of the Issuers upon a total
or partial liquidation or dissolution or reorganization of or similar proceeding
relating to any of the Issuers or the property thereof, the holders of Debenture
Specified Senior Indebtedness of the Issuers will be entitled to receive Payment
in full of such Debenture Specified Senior Indebtedness before the holders of
Debentures are entitled to receive any payment and until such Debenture
Specified Senior Indebtedness is paid in full, any payment or distribution to
which holders of Debentures would be entitled but for the subordination
provisions of the Debenture Indenture will be made to holders of such Debenture
Specified Senior Indebtedness as their interest may appear. If a distribution is
made to holders of Debentures that due to the subordination provisions should
not have been made to them, such holders of Debentures are required to hold it
in trust for the holders of Debenture Specified Senior Indebtedness of the
Issuers and pay it over to them as their interest may appear.
 
    If payment of the Debentures is accelerated because of an Event of Default,
the Issuers or the company or the Debenture Trustee shall promptly notify the
holders of the Debenture Specified Senior Indebtedness or the Representative of
such holders of the acceleration. None of the Issuers and the company may pay
the Debentures until five Business Days after such holders or the Representative
of the holders of Debenture Specified Senior Indebtedness of the Issuers receive
notice of such acceleration and, thereafter, may pay the Debentures only if the
subordination provisions of the Debenture Indenture otherwise permit payment at
that time.
 
    The obligations of the Company under the Debenture Guaranty are subordinated
to Debenture Specified Senior Indebtedness of the Company. The terms of the
subordination provisions described above with respect to the Issuers'
obligations under the Debentures apply equally to the Company and the
obligations of the Company under the Debenture Guaranty.
 
    By reason of such subordination provisions contained in the Debenture
Indenture, in the event of insolvency, creditors of the Issuers or the Company
who are holders of Debenture Specified Senior Indebtedness of the Issuers or the
Company, as the case may be, may recover more, ratably, that the holders of
Debentures, and creditors of the Issuers or the Company who are not holders of
Debenture
 
                                      105

Specified Senior Indebtedness of the Issuers or the Company, as the case may be,
may recover less, ratably, than holders of Debenture Specified Senior
Indebtedness and may recover more, ratably, than the holders of the Debentures.

    In addition, at any time and from time to time prior to February 1, 2001,
the Issuer may redeem in the aggregate up to 35% of the aggregate principal
amount at maturity of each of the Senior Notes originally issued, Senior
Subordinated Notes originally issued and the Debentures originally issued with
the net proceeds of one or more Public Equity Offerings, at a redemption price
(i) in the case of the Senior Notes, of 112% of the principal amount at maturity
at the redemption date thereof, plus accrued interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant Interest Payment Date), (ii) in the case of
the Senior Subordinated Notes, of 112.25% of the principal amount at maturity
thereof at the redemption date; and (iii) in the case of the Debentures, of
112.75% of the principal amount at maturity thereof at the redemption date
PROVIDED, HOWEVER, that at least $162.0 million principal amount at maturity of
Senior Notes or $132.0 million principal amount at maturity of Senior
Subordinated Notes or $35 million principal amount at maturity of Debentures, as
the case may be, must remain outstanding after each such redemption.
Nothwithstanding the foregoing, the ability of the Issuer to redeem Senior
Subordinated Notes pursuant to this provision may be limited by the limitations
on restricted payments under the Senior Note Indenture. Furthermore, the ability
of the Issuers to redeem Debentures pursuant to this provision may be limited by
the limitations or restricted payments under the Senior Note Indenture and the
Senior Subordinated Note Indentures.
 
    SELECTION OF NOTES FOR OPTIONAL REDEMPTION
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee on a pro rata basis, by lot or by such other method
as the Trustee in its sole discretion shall deem to be fair and appropriate;
PROVIDED, HOWEVER, that if a partial redemption is made with proceeds of a
Public Equity Offering, selection of the Securities or portion thereof for
redemption shall be made by the Trustee only on a pro rata basis, unless such
method is otherwise prohibited. The Securities may be redeemed in part in
multiples of $1,000 principal amount only. Notice of redemption will be sent, by
first class mail, postage prepaid, at least 30 days prior to the date fixed for
redemption to each holder whose Securities are to be redeemed at the last
address for such holder then shown on the registry books. If any Securities is
to be redeemed in part only, the notice of redemption that relates to such
Security shall state the portion of the principal amount thereof to be redeemed.
A new Security in principal amount equal to the unredeemed portion thereof will
be issued in the name of the holder thereof upon cancelation of the original
Security. On and after any redemption date, interest will cease to accrue on the
Securities or part thereof called for redemption as long as the Note Issuers
have deposited with the Paying Agent funds in satisfaction of the redemption
price pursuant to the Indenture.
 
NOTES CASH FLOW SWEEP
 
    No later than the fifteenth day following the last day of each fiscal
quarter of the Company (as the Company's fiscal year is in effect on the Issue
Date), the Company shall deposit into the Notes Sinking Fund Account an amount
equal to the Cash Flow Sweep Amount.
 
ADDITIONAL AMOUNTS
 
    (a) All payments made by the Note Issuers under or with respect to the
Securities and by the Company under the Guaranties will be made free and clear
of and without withholding or deduction for or
 
                                      107

on account of any present or future taxes, levies, duties, fees, assessments or
other governmental charges of whatever nature ("Taxes") imposed, levied,
collected or assessed by or on behalf of any taxing authority within the Cayman
Islands or Thailand, unless the Note Issuers are or the Company is, as the case
may be, required to withhold or deduct Taxes by law or by the interpretation or
administration thereof. If the Note Issuers are or the Company is required to
withhold or deduct or if the Note Issuers are or the Company is otherwise
required to pay any amount for or on account of Taxes imposed by a taxing
authority within the Cayman Islands or Thailand from or in respect of any
payment made under or with respect to the Securities or the Guaranties, the Note
Issuers or the Company, as the case may be, will pay such additional amounts
("Additional Amounts") as may be necessary so that the net amount received by
each holder and beneficial owner of Securities (including Additional Amounts)
after such withholding or deduction or other payment of Taxes will not be less
than the amount the holder and beneficial owner would have received if such
Taxes had not been withheld or deducted or paid; PROVIDED that no Additional
Amounts will be payable with respect to a payment made to a holder of Securities
with respect to any Tax: (i) which would not have been imposed, payable or due
but for the existence of any present or former connection between the holder (or
the beneficial owner of, or person ultimately entitled to obtain an interest in,
such Securities) and the Cayman Islands or Thailand, as the case may be, other
than the mere holding of the Securities; (ii) which would not have been imposed,
payable or due if the Securities are held in definitive registered form
("Definitive Registered Notes") and the presentation of Definitive Registered
Notes for payment had occurred within 30 days after the date such payment was
due and payable or was provided for, whichever is later, except for Additional
Amounts with respect to Taxes that would have been imposed had the holder
presented the Note for payment within such 30-day period; (iii) that is an
estate, inheritance, gift, sales, transfer, personal property or similar Tax;
(iv) that is imposed or withheld by reason of the failure of the holder or
beneficial owner of a Security to comply, at the reasonable request of the Note
Issuers or the Company, as the case may be, with certification, information or
other reporting requirements concerning the nationality, residence or identity
of the holder or such beneficial owner if such compliance is required or imposed
by a statute, treaty, regulation or administrative practice of the taxing
jurisdiction as a precondition to exemption from all or part of such Tax; (v) if
the beneficial owner of, or person ultimately entitled to obtain an interest in,
such Securities had been the holder of the Securities and would not be entitled
to the payment of Additional Amounts; or (vi) payable otherwise than by
withholding from payments on or in respect of any Security.
 
    (b) The Note Issuers or the Company, as the case may be, will also (i) make
such withholding or deduction and (ii) remit the full amount deducted or
withheld to the relevant authority in accordance with applicable law. The Note
Issuers or the Company, as the case may be, will make reasonable efforts to
obtain certified copies of tax receipts evidencing the payment of any Taxes so
deducted or withheld from each taxing authority imposing such Taxes. The Note
Issuers or the Company, as the case may be, will furnish to the holders of the
Securities, within 60 days after the date the payment of any Taxes so deducted
or withheld is due pursuant to applicable law, either certified copies of tax
receipts evidencing such payment by the Note Issuers or the Company, as the case
may be, or, if such receipts are not obtainable, other evidence of such payments
by the Note Issuers or the Company.
 
    (c) In addition, the Note Issuers or the Company, as the case may be, will,
upon written request of each holder of Securities (subject to the exclusions set
forth in (i), (ii), (iii), (iv), (v) and (vi) of paragraph (a) above), and
PROVIDED that reasonable supporting documentation is provided, reimburse each
such holder for the amount of any Taxes levied or imposed by the Cayman Islands
or Thailand and paid by such holder as a result of payments made under or with
respect to the Securities or under the relevant Guaranty. Any payment pursuant
to this section shall be an Additional Amount.
 
    (d) At least 30 days prior to each date on which any payment under or with
respect to the Securities or under the Guaranties is due and payable, if the
Note Issuers or the Company will be obligated to pay Additional Amounts with
respect to such payment, the Notes Issuers or the Company will deliver to the
Trustee an Officers' Certificate stating the fact that such Additional Amounts
will be payable and the amounts so payable and will set forth such other
information necessary to enable the Trustee to pay such
 
                                      108

Additional Amounts to the holders of Securities on the payment date. Whenever in
the Indentures or in this "Description of Notes and Guaranties" there is
mentioned, in any context, the payment of amounts based upon the principal of,
premium, if any, interest or of any other amount payable under or with respect
to any Security or any Guaranty such mention shall be deemed to include mention
of the payment of Additional Amounts to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof.
 
    (e) In addition, the Note Issuers will pay any stamp, issue, registration,
documentary, value added or other similar taxes and other duties (including
interest and penalties) payable in the Cayman Islands or in Thailand (or any
political subdivision or taxing authority of either jurisdiction) and in the
United States in respect of the creation, issue, offering, execution or
enforcement of the Securities, the Guaranties or any documentation with respect
thereto.
 
OPTIONAL TAX REDEMPTION
 
    The Securities may be redeemed at the option of the Note Issuers or paid in
full at the option of the Company, in whole but not in part, upon not less than
30 nor more than 60 days' notice given as provided in the Indenture, at any time
at 103% of the principal amount thereof, plus accrued and unpaid interest to the
date fixed for such payment if, as a result of any change in or amendment to the
laws, regulations or governmental policy having the force of law of the Cayman
Islands or Thailand (or of any political subdivision or taxing authority thereof
or therein) or any execution of or amendment to, any treaty or treaties
affecting taxation of which the Cayman Islands or Thailand (or such political
subdivision or taxing authority) is a party, which becomes effective on or after
the date of the Indenture (i) (A) the Note Issuers are required, or would be
required on the next succeeding interest payment date, to pay Additional Amounts
in respect of payments on the Securities as a result of the imposition of Taxes
imposed by the Cayman Islands or Thailand (or any political subdivision or
taxing authority of either jurisdiction); (B) the Company is, or on the next
succeeding interest payment date would be, unable for reasons outside of its
control, to procure payment by the Note Issuers and, with respect to any payment
due, or to become due, under the Securities or the Guaranties, the Company is
required, or would be required on the next succeeding Interest Payment Date, to
pay Additional Amounts as a result of the imposition of Taxes by the Cayman
Islands or Thailand or (C) with respect to any payment to a Note Issuer to
enable a Note Issuer to make any payments under the Securities, the Company or
NSM Cayman is, or on the next interest payment date would be, required to deduct
or withhold Taxes imposed by the Cayman Islands or Thailand (or any political
subdivision or taxing authority of either jurisdiction) and (ii) the payment of
such Additional Amounts cannot be avoided by the use of any reasonable measures
available to the Note Issuers or the Company that do not require undue effort or
costs (including, without limitation, the Company making payments directly to
holders under the applicable Guaranty). In addition, the Note Issuers or the
Company, as the case may be, will also pay to holders on the redemption date any
Additional Amounts which would otherwise be payable; PROVIDED, HOWEVER, that no
such notice of redemption shall be given earlier than 90 days prior to the
earliest date on which the Issuers or the Company, as the case may be, would be
obligated to pay such Additional Amounts if a payment in respect of the Notes or
a Guaranty were then due.
 
    Prior to the publication of the notice of redemption in accordance with the
foregoing, the Note Issuers or the Company shall deliver to the Trustee an
officer's certificate stating that (x) the Note Issuers are or the Company is
entitled to effect such redemption based on a written opinion of counsel or
written advice of a nationally recognized independent tax counsel, such opinion
or advice being reasonably acceptable to the Trustee, that the condition
referred to in either of subclauses (A) or (B) or (C) of clause (i) of the
immediately preceding paragraph is satisfied as a result of such change,
amendment or executed or amended treaty and (y) the condition described in (ii)
of the immediately preceding paragraph is satisfied. Such notice, once delivered
by the Note Issuers or the Company to the Trustee, will be irrevocable.
 
                                      109

REPURCHASE AT THE OPTION OF HOLDERS
 
    CHANGE OF CONTROL
 
    The Indentures provide that upon the occurrence of a Change of Control each
holder will have the right to require the Note Issuers to repurchase all or any
part of such holder's Securities at a purchase price in cash equal to 101% of
the Accreted Value thereof on the date of purchase, plus accrued and unpaid
interest and Additional Amounts, if any, to the date of repurchase (subject to
the right of holders of record on the relevant record date to receive interest
due on the relevant Interest Payment Date).
 
    The Senior Note Indenture limits the repurchase of Senior Subordinated Notes
and the Debentures. Prior to repurchasing any Senior Subordinated Notes or
Debentures pursuant to this covenant, the Note Issuers shall (i) repay in full
the Senior Notes or (ii) otherwise obtain the requisite consent under the Senior
Notes to permit the repurchase of the Senior Subordinated Notes or Debentures.
The Senior Subordinated Note Indenture limits the repurchase of the Debentures
in a similar manner. Failure to make a Change of Control offer in respect of the
Senior Notes, Senior Subordinated Notes or the Debentures, as the case may be,
constitutes an Event of Default under the applicable Indenture.
 
    The Indentures provide that within 30 days following any Change of Control,
the Note Issuers shall mail a notice to each holder with a copy to the Trustee
stating: (i) that a Change of Control has occurred and that such holder has the
right to require the Issuers to repurchase such holder's Securities at a price
in cash equal to 101% of the Accreted Value thereof on the date of purchase,
plus accrued and unpaid interest and Additional Amounts, if any, to the date of
repurchase (subject to the right of holders of record on the relevant record
date to receive interest on the relevant Interest Payment Date), (ii) the
repurchase date (which shall not be earlier than 30 days nor later than 60 days
from the date such notice is mailed); and (iii) the procedures determined by the
Note Issuers, consistent with the Indentures, that a holder must follow in order
have its Securities purchased.
 
    The Note Issuers will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of the Indentures, the Note Issuers will
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations described in the Indentures by virtue
thereof.
 
    The definition of "Change of Control" includes, among other transactions, a
disposition of all or substantially all of the property and assets of the
Issuers or the Company, including a transaction permitted under the "Merger and
Consolidation" covenant. With respect to the disposition of property or assets,
the phrase "all or substantially all" as used in the Indentures varies according
to the facts and circumstances of the subject transaction, has no clearly
established meaning under New York law (which is the choice of law under the
Indentures) and is subject to judicial interpretation. Accordingly, in certain
circumstances there may be a degree of uncertainty in ascertaining whether a
particular transaction would involve a disposition of "all or substantially all"
of the property or assets of a Person, and therefore it may be unclear as to
whether a Change of Control has occurred and whether the Issuers are required to
make an offer to repurchase the Securities as described above.
 
    The exercise by the holders of their right to require the Note Issuers or
the Company, as the case may be, to repurchase the Securities could cause a
default under other Indebtedness, even if the Change of Control itself does not,
due to the financial effect of such repurchase on the Note Issuers or the
Company, as the case may be. Finally, the Note Issuers' or the Company's, as the
case may be, ability to pay cash to the holders upon a repurchase may be limited
by the Note Issuers' or the Company's then existing financial resources. There
can be no assurance that sufficient funds will be available when necessary to
make any required repurchases.
 
                                      110

    The existence of a holders' right to require the Note Issuers or the Company
to repurchase such holder's Notes upon the occurrence of a Change of Control may
deter a third party from seeking to acquire the Company in a transaction that
would constitute a Change of Control.
 
    SALES OF ASSETS AND SUBSIDIARY STOCK.
 
    The Indentures will provide that the Company shall not, and shall not permit
either of the Note Issuers or any Restricted Subsidiaries to, make any Asset
Disposition unless (i) the Company, the Note Issuers or such Restricted
Subsidiary receives consideration at the time of such Asset Disposition at least
equal to the fair market value, as determined in good faith by the Company's
board of directors (including as to the value of all noncash consideration), of
the shares and assets subject to such Asset Disposition, (ii) at least 80% of
the consideration thereof received by the Company, the Note Issuers or such
Restricted Subsidiary is in the form of cash or Cash Equivalents and (iii) an
amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied (A) if at the time of the Asset Disposition the Company has not yet
achieved Profitable Operations, pro rata to a mandatory offer by the Note
Issuers and the Company to purchase Securities at 101% of the Accreted Value
thereof on the date of purchase, plus accrued and unpaid interest and Additional
Amounts, if any, thereon, and the repayment of principal and accrued and unpaid
interest, if any, under the Bank Credit Facility and (B) if at the time of the
Asset Disposition the Company has achieved Profitable Operations, at the
Company's option either to (1) the investment in or acquisition of Additional
Assets within 365 days from the later of such Asset Disposition and the receipt
of such Net Available Cash or (2) pro rata to a mandatory offer by the Note
Issuers and the Company to purchase Securities at 101% of the Accreted Value
thereof on the date of purchase plus accrued and unpaid interest and Additional
Amounts, if any, thereon, and the repayment of principal and accrued and unpaid
interest, if any, under the Bank Credit Facility; PROVIDED that the Note Issuers
and the Company shall be required to redeem Indebtedness pursuant to clause (2)
to the extent of the balance of such Net Available Cash after application in
accordance with clause (1). Notwithstanding the foregoing provisions, Net
Available Cash shall not be required to be applied in accordance herewith to the
extent that the aggregate Net Available Cash from all Asset Dispositions which
are not applied in accordance with this covenant at any time does not exceed
U.S.$10 million. The Note Issuers shall not be required to make an offer to
purchase Securities pursuant to this covenant if the Net Available Cash
available therefor (after application of the proceeds as provided in clause (A))
is less than U.S.$10 million for any particular Asset Disposition (which lesser
amounts shall be carried forward for purposes of determining whether an offer is
required with respect to the Net Available Cash from any subsequent Asset
Disposition).
 
    Notwithstanding the foregoing, to the extent the Senior Note Indenture
limits the repurchase of Senior Subordinated Notes and the Debentures, the Note
Issuers shall not be required to make an offer hereunder for the repurchase of
Senior Subordinated Notes or the Debentures. Similarly, to the extent the Senior
Subordinated Note Indenture limits the repurchase of the Debentures the Issuers
shall not be required to make an offer hereunder for the repurchase of the
Debentures.
 
    For the purposes of this covenant, the following will be deemed to be cash:
(x) the assumption by the transferee of Senior Indebtedness of the Company, the
Note Issuers or any Restricted Subsidiary and the release of the Company, the
Note Issuers or any Restricted Subsidiary from all liability on such Senior
Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company, the Note Issuers or any Restricted Subsidiary from the
transferee that are promptly (and in any event within 60 days) converted by the
Company, the Note Issuers or such Restricted Subsidiary into cash.
 
    OFFER TO REPURCHASE UPON FAILURE TO ATTAIN PROFITABLE OPERATIONS.
 
    As set forth under "Description of Notes and Guaranties--Credit Support",
the Note Issuers and the Company will deposit all of the Notes Net Proceeds
(other than amounts required to be deposited in the Notes DSR Account), together
with the balance of the proceeds of the Debenture Offering and any Equity
Investment Proceeds, into the Offshore Reserve Account to be established and
maintained with the
 
                                      111

Collateral Agent or another Qualifying Financial Institution. If the Company
does not achieve Profitable Operations prior to December 31, 2001, the Note
Issuers shall be required to use any amounts in the Offshore Reserve Account to
undertake a Stage III Tender.
 
    The Note Issuers will be required to purchase Securities tendered pursuant
to a Stage III Tender in accordance with the procedures set forth in the
Indentures.
 
    The Note Issuers will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to the
Indentures. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Issuers will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under the Indentures by virtue thereof.
 
CERTAIN COVENANTS
 
    The Indentures contain certain covenants including, among others, the
following:
 
    LIMITATION ON INDEBTEDNESS.  (a) Neither the Note Issuers or the Company
shall Incur, nor shall the Company permit any Restricted Subsidiary to Incur,
directly or indirectly, any Indebtedness on or after the Issue Date unless on
the date of such Incurrence and after giving effect thereto the Consolidated
Coverage Ratio would be greater than 3.0:1.0.
 
    (b) Notwithstanding the foregoing paragraph (a), the Note Issuers or the
Company may Incur on or after the Issue Date the following Indebtedness:

is deemed to be so designated, a "Restricted Payment" shall be deemed to have
been made in an amount equal to the fair value of the Investment of the Company
and its other Restricted Subsidiaries in such Restricted Subsidiary as
determined by the Board of Directors with the concurrence of a majority of the
Independent Directors (there being at least one Independent Director), whose
good faith determination shall be conclusive. If a particular Restricted Payment
involves a non-cash payment, including a distribution of assets, then such
Restricted Payment shall be deemed to be in an amount equal to the fair market
value of the non-cash portion of such Restricted Payment as determined by the
Board of Directors, whose good faith determination shall be conclusive.
 
    LIMITATION ON LIENS.  Neither the Note Issuers nor the Company will affirm

the Note Issuers or the Company or another Restricted Subsidiary and the
designation of such Subsidiary as an

such transaction as having been Incurred by the Successor Company at the time of
such transaction), no Default or Event of Default shall have occurred and be
continuing (or would result therefrom); (iii) immediately after giving effect to
such transaction on a pro forma basis (and treating any Indebtedness which

there will
 
                                      117

be no additional Thai Taxes and no Taxes of any other jurisdiction imposed on
any payments made pursuant to the Notes or the Guaranties; and (vi) each of the
Company and the Note Issuers shall have delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, stating that such consolidation, merger

contemplated by the Security Documents) continue in full force and effect.

other Person, and all of its outstanding Capital Stock shall at all times be
owned by the Company free and clear of all Liens (other than Liens securing the

Exchange Act, the Note Issuers will nevertheless deliver Exchange Act
information to the holders of the Securities within 15 days after they would
have been required to file it with the Commission.
 
    INTERCOMPANY NOTE AND CAPITAL CONTRIBUTIONS. (a) On the Issue Date, the

amount that any payment (whether a payment of principal when due at Stated
Maturity, upon optional redemption, upon required repurchase, upon declaration
or otherwise or a payment in respect of any interest) is due on the Notes;
PROVIDED, HOWEVER, if after the Issue Date the Issuers and the Company determine
in good faith that such an intercompany note obligation will result in a
material adverse tax consequence to the Issuers or the Company, the Issuers and
the Company may cancel such intercompany note obligation and the Company shall
thereafter comply with clause (b) below.
 
    (b) In the event that at any time the intercompany note referenced in clause
(a) above has been canceled or otherwise is inoperative or unenforceable, then
on or prior to any Interest Payment Date in respect of any Note, or any date
upon which any payment of principal of any Note is required to be made when due
at its Stated Maturity, upon optional redemption, upon required repurchase, upon
declaration or otherwise, the Company shall make a cash contribution to NSM
Cayman in the amount of such interest or principal payment, as the case may be.

Note Issuers or the Company to comply for 60 days after notice with its other

Subsidiary and such judgment or decree shall remain undischarged or unstayed for
a period of 60 days after such judgment becomes final and nonappealable (the
"judgment default provision"), (j) any Account is not maintained as required or
any drawing under any Account is not made when required to be made and in any
such case such failure continues unremedied for five Business Days (or, in the
case of a failure to maintain any required amount in, or to make a drawing
under, the Notes DSR Account, 30 days) (the "account provision"), (k) the
Security Documents shall cease to grant the holders any of the material
collateral or rights purported to be granted thereunder (the "security
provision") or (l) after giving effect to the anticipated receipt and
application of any insurance proceeds, the Mill is abandoned in whole or in
substantial part or is destroyed or made permanently inoperable in whole or in
substantial part (the "abandonment provision").
 
    However, a default under clauses (d) or (e) will not constitute an Event of
Default until the Trustee or the holders of 25% in principal amount at maturity
of the outstanding Senior Notes, Senior Subordinated Notes or the Debentures, as
the case may be, notify the Issuers (with a copy to the Trustee if given by the
holders) of the Default and such Default is not cured within the time specified
in clause (d) or (e) after receipt of such notice.
 
    If an Event of Default with respect to the Senior Notes occurs (other than
an Event of Default with respect to the Issuers or the Company pursuant to the
bankruptcy provision) and is continuing, the Senior Note Trustee or the holders
of at least 25% in principal amount at maturity of the outstanding Senior Notes
by notice to the Note Issuers and the Senior Note Trustee (if the notice is
given by the holders) may declare the Accreted Value as of the date on which the
Senior Notes first become due and payable plus accrued and unpaid interest, if
any, on all the Senior Notes to be due and payable. If an Event of Default with
respect to the Senior Subordinated Notes occurs (other than an Event of Default
with respect to the Note Issuers or the Company pursuant to the bankruptcy
provision) and is continuing, the Senior Subordinated Note Trustee or the
Holders of at least 25% in principal amount at maturity of the outstanding
Senior Subordinated Notes by notice to the Note Issuers and the Senior
Subordinated Note Trustee (if the notice is given by the holders) may declare
the Accreted Value as of the date on which the Senior Subordinated Notes first
became due and payable plus accrued and unpaid interest, if any, on all the
Senior Subordinated Notes to be due and payable. If an Event of Default with
respect to the Debentures occurs (other than an Event of Default with respect to
the Note Issuers or the Company pursuant to the bankruptcy provisions) and is
continuing, the Debenture Trustee or the Holders of least 25% in principal
amount at maturity of the outstanding Debentures by notice to the Note Issuers
and the Debenture Trustee (if notice is given by the holders) may declare the
Accreted Value as of the date on which the Debentures first become due and
payable plus accrued and unpaid interest, if any, on all Debentures to be due
and payable. In either case, upon such a declaration, such Accreted Value and
accrued and unpaid interest shall be due and payable immediately. If an Event of
Default with respect to the Senior Notes, the Senior Subordinated Notes or
Debentures pursuant to the bankruptcy provision occurs, the Accreted Value of,
and accrued and unpaid interest on, such Securities will become and be
 
                                      119

immediately due and payable without any declaration or other act on the part of
the Trustee or any holders. Under certain circumstances, the holders of a
special majority of 60% in principal amount of the outstanding Senior Notes or
the holders of a special majority of 60% in principal amount of the outstanding
Senior Subordinated Notes or the holders of a special majority of 60% in
principal amount of the outstanding Debentures may rescind any such acceleration
with respect to the Senior Notes or Senior Subordinated Notes or Debentures,
respectively, and its consequences.
 
    Subject to the provisions of each Indenture relating to the duties of each
Trustee, if an Event of Default occurs and is continuing, such Trustee will be
under no obligation to exercise any of the rights or powers under the applicable
Indenture at the request or direction of any of the holders unless such holders
have offered to such Trustee reasonable indemnity or security against any loss,
liability or expense resulting therefrom. Except to enforce the right to receive
payment of principal, premium (if any) or interest when due, no holder may
pursue any remedy with respect to the applicable Indenture or the applicable
Notes unless (a) such holder has previously given the applicable Trustee written
notice that an Event of Default is continuing, (b) holders of at least 25% in
principal amount at maturity of the outstanding Senior Notes or Senior
Subordinated Notes or Debentures, as the case may be, have requested the
applicable Trustee to pursue the remedy, (c) such holders have offered the
applicable Trustee reasonable security or indemnity against any loss, liability
or expense, (d) the applicable Trustee has not complied with such request within
60 days after the receipt of the request and the offer of security or indemnity
and (e) the holders of a majority in principal amount at maturity of the
outstanding Senior Notes or Senior Subordinated Notes or Debentures, as the case
may be, have not given the Trustee a direction that, in the reasonable opinion
of the Trustee, is inconsistent with such request within such 60-day period.
Subject to certain restrictions, the holders of a majority in principal amount
at maturity of the outstanding Senior Notes or Senior Subordinated Notes or
Debentures, as the case may be, are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the
applicable Trustee or of exercising any trust or power conferred on such
Trustee. Such Trustee, however, may refuse to follow any direction that
conflicts with law or the applicable Indenture or that such Trustee determines
is unduly prejudicial to the rights of any other holder or that would involve
such Trustee in personal liability. Prior to taking any action under the
applicable Indenture, the applicable Trustee shall be entitled to
indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.
 
    Such Indenture provides that if a Default occurs and is continuing and is
known to the applicable Trustee, such Trustee must mail to each holder notice of
the Default within 60 days after it occurs. Except in the case of a Default in
the payment of principal of, premium or Additional Amounts (if any) or interest
on any Senior Notes or Senior Subordinated Notes or Debentures, as the case may
be, the Trustee may withhold notice if and so long as its board of directors, a
committee of its board of directors or a committee of its Trust officers in good
faith determines that withholding notice is in the interests of the holders. In
addition, the Note Issuers are required to deliver to each Trustee within 90
days after the end of each fiscal year, a certificate indicating whether the
signers thereof know of any Default that occurred during the previous year. The
Note Issuers also are required to deliver to each Trustee, within 30 days after
the occurrence thereof, written notice of any events which would constitute
certain Defaults.
 
AMENDMENTS AND WAIVERS
 
    Subject to certain exceptions, each Indenture may be amended with the
consent of the holders of a majority in principal amount at maturity of the
Senior Notes or Senior Subordinated Notes or Debentures, as the case may be,
then outstanding and any existing Default and its consequences (including,
without limitation, an acceleration of the Notes) or compliance with any
provisions may be waived with the consent of the holders of a majority in
principal amount at maturity of the Senior Notes or Senior Subordinated Notes or
Debentures, as the case may be, then outstanding. However, without the consent
of each holder of outstanding Senior Notes or Senior Subordinated Notes or
Debentures, as the case may be, affected, no amendment, supplement or waiver
may, among other things, (i) reduce the principal amount at maturity of
 
                                      120

Senior Notes or Senior Subordinated Notes or Debentures, as the case may be
whose holders must consent to an amendment, supplement or waiver, (ii) reduce
the stated rate of or extend the stated time for payment of interest on any
Senior Note or Senior Subordinated Note or Debentures, as the case may be, (iii)
reduce the principal of or extend the Stated Maturity of any Senior Note or
Senior Subordinated Note or Debentures, as the case may be, (iv) reduce the
premium payable upon the redemption or repurchase of any Senior Note or Senior
Subordinated Note or Debentures, as the case may be, or change the time at which
any Senior Note or Senior Subordinated Note or Debentures, as the case may be,
may be redeemed or repurchased under the applicable Indenture, (v) make any
Senior Note or Senior Subordinated Note or Debentures, as the case may be,
payable in money other than that stated in such Security, (vi) impair the right
of any holder to receive payment of principal of and interest on such holder's
Senior Notes or Senior Subordinated Notes or Debentures, as the case may be on
or after the due dates therefor or to institute suit for the enforcement of any
payment on or with respect to such holder's Notes, (vii) release the Guaranties,
all or substantially all of the Collateral or the requirement to maintain any
Account or (viii) make any change in the amendment provisions which require each
holder's consent or in the waiver provisions.
 
    Without the consent of any holder of Senior Notes or Senior Subordinated
Notes or Debentures, as the case may be , the Note Issuers and the applicable
Trustee may amend the applicable Indenture (and such Trustee and the Company may
amend the applicable Guaranty) to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation,
partnership, trust or limited liability company of the obligations of the Note
Issuers under such Indenture (or of the Company under such Guaranty), to provide
for uncertificated Securities in addition to or in place of certificated
Securities (PROVIDED that the uncertificated Securities are issued in registered
form for purposes of Section 163(f) of the Code, or in a manner such that the
uncertificated Securities are described in Section 163(f)(2)(B) of the Code), to
add further Guaranties with respect to the Securities, to add further collateral
security for the Securities, to add to the covenants for the benefit of the
holders or to surrender any right or power conferred upon the Note Issuers or
the Company, to make any change that does not adversely affect the rights of any
holder or to comply with any requirement of the Commission in connection with
the qualification of the Indentures under the Trust Indenture Act.
 
    The consent of the holders of Senior Notes or Senior Subordinated Notes or
Debentures, as the case may be is not necessary under the applicable Indenture
to approve the particular form of any proposed amendment. It is sufficient if
such consent approves the substance of the proposed amendment.
 
    After an amendment under the applicable Indenture or to the applicable
Guaranty becomes effective, the Issuers are required to mail to the holders a
notice briefly describing such amendment. However, the failure to give such
notice to all the holders, or any defect therein, will not impair or affect the
validity of the amendment.
 
DEFEASANCE
 
    The Note Issuers at any time may terminate all of their and the Company's
obligations under the Senior Notes or Senior Subordinated Notes or Debentures,
as the case may be and the applicable Indenture ("legal defeasance"), except for
certain obligations, including those respecting the defeasance trust and
obligations to register the transfer or exchange of the Senior Notes or Senior
Subordinated Notes or Debentures, as the case may be, to replace mutilated,
destroyed, lost or stolen Senior Notes or Senior Subordinated Notes or
Debentures, as the case may be and to maintain a registrar and paying agent in
respect of the Senior Notes or Senior Subordinated Notes or Debentures, as the
case may be. The Note Issuers at any time may terminate their and the Company's
obligations under the covenants described under "--Certain Covenants" (other
than under "Merger and Consolidation"), the operation of the cross acceleration
provision, the bankruptcy provision with respect to the Company and
Subsidiaries, the judgment default provision, the account provision, the
security provision and the abandonment provision
 
                                      121

described under "Events of Default" above and the limitations contained in
clauses (iii) and (iv) under "-- Certain Covenants--Merger and Consolidation"
("covenant defeasance").
 
    The Note Issuers may exercise their legal defeasance option notwithstanding
their prior exercise of their covenant defeasance option. If the Note Issuers
exercises their legal defeasance option, payment of the Senior Notes or Senior
Subordinated Notes or Debentures, as the case may be may not be accelerated
because of an Event of Default with respect thereto and the Company will be
released from the applicable Guaranty. If the Note Issuers exercises their
covenant defeasance option, payment of the Senior Notes or Senior Subordinated
Notes or Debentures, as the case may be may not be accelerated because of an
Event of Default specified in clause (d), (e), (f), (g), (h) (with respect only
to the Company and its Subsidiaries), (i), (j), (k) or (l) under "Events of
Default" above.
 
    If the Note Issuers exercises its legal defeasance option or covenant
defeasance option, the Company will be released from all its obligations with
respect to the applicable Guaranty and all the Collateral will be released.
 
    In order to exercise either defeasance option, the Note Issuers must
irrevocably deposit in trust (the "defeasance trust") with the applicable
Trustee money or U.S. Government Obligations for the payment of principal,
premium (if any) and interest on the Senior Notes or Senior Subordinated Notes
or Debentures, as the case may be to redemption or maturity, as the case may be,
and must comply with certain other conditions, including delivery to the
applicable Trustee of an Opinion of Counsel to the effect that holders of the
Senior Notes or Senior Subordinated Notes or Debentures, as the case may be will
not recognize income, gain or loss for U.S. Federal income tax purposes as a
result of such deposit and defeasance and will be subject to U.S. Federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and defeasance had not occurred (and, in the
case of legal defeasance only, such Opinion of Counsel must be based on a ruling
of the Internal Revenue Service or other change in applicable U.S. Federal
income tax law).
 
CONCERNING THE TRUSTEE
 
    The Chase Manhattan Bank is to be the Trustee under the Senior Note
Indenture, the Senior Subordinated Note Indenture, and the Debenture Indenture
and, in each case, has been appointed by the Note Issuers as Collateral Agent
and as registrar and paying agent with regard to the respective Securities.
 
    Each Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Note Issuers, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim a security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest (as defined) it
must eliminate such conflict or resign.
 
    The holders of a majority in aggregate principal amount of the then
outstanding Senior Notes, Senior Subordinated Notes or Debentures, as the case
may be issued under the applicable Indenture will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy
available to the applicable Trustee. Directions to the Collateral Agent will be
effective as provided above under "Security Arrangements--Enforcement of
Collateral." Each Indenture provides that in case an Event of Default shall
occur (which shall not be cured) the applicable Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent person in the
conduct of their own affairs. Subject to such provisions, such Trustee will be
under no obligation to exercise any of its rights or powers under the applicable
Indenture at the request of any of the holders of the Senior Notes or Senior
Subordinated Notes, as the case may be issued thereunder unless they shall have
offered to such Trustee security and indemnity satisfactory to it.
 
                                      122

GOVERNING LAW
 
    Each Indenture and the Securities will be governed by, and construed in
accordance with, the laws of the State of New York without giving effect to
applicable principles of conflicts of law to the extent that the application of
the law of another jurisdiction would be required thereby. The various
agreements creating and governing the Collateral will be governed by, and
construed in accordance with, the laws of the State of New York and Thailand.
 
ENFORCEABILITY OF JUDGMENTS
 
    Since all of the operating assets of the Issuers and the Company are outside
the United States, any judgment obtained in the United States against the
Issuers or the Company, including judgments with respect to the payment of
principal, interest, redemption price and any purchase price with respect to the
Notes, may not be collectible within the United States. However, the Issuers and
the Company have been advised by their Thai legal counsel, White & Case
(Thailand) Limited, that any judgment or order obtained in a court outside
Thailand, including the United States, would not be enforced as such by the
courts of Thailand, but such judgment or order in the discretion of the courts
of Thailand may be admitted as evidence of an obligation in new proceedings
instituted in the courts of Thailand, which would consider the issue on the
evidence before it.
 
CONSENT TO JURISDICTION AND SERVICE
 
    The Issuers and the Company have appointed CT Corporation System, 1633
Broadway, New York, New York 10019 as their agent for actions brought with
respect to the Notes, the Guaranties and/or the Indentures in any Federal or
state court located in the Borough of Manhattan in The City of New York and will
submit to such jurisdiction.

COLLATERAL FOR THE SECURITIES AND THE GUARANTIES
 
    The Note Issuers' obligations under the Securities are secured by a pledge
of the capital stock of NSM (Del) (together with the shares described in clause
(viii) of the immediately following sentence, the "Pledged NSM Stock"). Subject
to certain exceptions described herein, the Company's obligations under the
Guaranties (other than the Debenture Guaranty) are secured equally and ratably,
on a first priority basis, by (i) a first mortgage over the land and buildings
comprising the Mill (except for the Co-Gen Facility); (ii) a security interest
in all amounts in the Offshore Reserve Account and the Notes DSR Account; (iii)
a security interest in all machinery and equipment located at the Mill; (iv) an
assignment of all insurance and reinsurance policies maintained by the Company
on the Mill; (v) an assignment of the Company's rights and benefits under the
Project Documents; (vi) an assignment and pledge of the Revenue Account,
Operating Account and Notes Sinking Fund Account; (vii) a pledge of Permitted

and (ix) an assignment of Performance Bonds (all such collateral security, the
"Collateral").
 
    The Collateral (other than the Offshore Reserve Account and the Notes DSR
Account and the pledge of shares of NSM Cayman) also secures, on an equal and
ratable first priority basis with the Notes and the Guaranties (other than the
Debenture Guaranty), the Indebtedness under the Bank Credit Facility. In
addition, all Collateral secures, on a second priority basis, the obligations of
the Company in respect of the Debenture Guaranty. The respective rights in the
Collateral of the holders of the Notes, the Thai lenders under the Bank Credit
Facility and the holders of the Debentures are governed by the terms of the
Security Sharing Agreement. In the event of a default under the Senior
Indebtedness, there can be no assurance that proceeds upon a distribution will
be sufficient to repay amounts due under the senior Indebtedness, including the
Notes and the Guaranties. See "Risk Factors--No Assurance of Adequate
Collateral; Shared Collateral."
 
THE SECURITY DOCUMENTS
 
    The Security Documents which create an interest in the various types of
Collateral are as follows: (i) a security interest in the land and buildings
comprising the Mill, except the Co-Gen Facility, has been granted pursuant to a
mortgage; (ii) a security interest in the proceeds in the Offshore Reserve
Account and the Notes DSR Account has been granted pursuant to a conditional
assignment; (iii) a security interest in all machinery and equipment located at
the Mill has been granted initially pursuant to a pledge, and later, for
Registrable Machinery, to be converted to a machinery mortgage; (iv) a security
interest in the insurance policies covering the Mill has been granted pursuant
to an assignment and an assignment of all reinsurance; (v) a security interest
in the rights and benefits under the Project Documents has been granted pursuant
to a conditional assignment; (vi) a security interest in the Operating Account,
Revenue Account and Notes Sinking Fund Account has been granted pursuant to an
assignment and pledge; (vii) a security interest in Permitted Investments has
been granted pursuant to a pledge; (viii) a security interest in all issued and
outstanding shares of each of the Note Issuers has been granted pursuant to a
pledge and (ix) a security interest in the Performance Bonds has been granted
pursuant to an assignment. Other than the pledge of shares and the security
interest in the Offshore Reserve Account, Notes DSR Account and Notes Sinking
Fund Account, which are governed by New York law, the Security Documents are
governed by and construed in accordance with Thai law.
 
    The following summaries do not purport to be a complete description of the
Security Documents or the Security Sharing Agreement referred to below.
 
SECURITY RIGHTS IN LAND AND BUILDINGS
 
    In Thailand, land ownership is governed primarily by the Land Code, B.E.
2497 (1954) (the "Land Code"), its implementing regulations and Book IV of the
Civil and Commercial Code (the "CCC").
 
                                      139

    Title deeds are the most secure form of evidence of land ownership in
Thailand. However, title deeds are not issued for land located in unsurveyed
areas of Thailand.
 
    The approximately 494 rai of land on which the Mill is located is held under
17 separate land title deeds. Under the land title deeds, the Company has the
right to erect, own, occupy and use buildings on such land.
 
    The Mill is located in the Chonburi Industrial Estate (Bo Win) which is
managed by the Hemmaraj Land and Development Public Company Limited ("Hemmaraj")
under the authority of the Industrial Estate Authority of Thailand ("IEAT"). The
Company initially purchased a majority of the land located at the Mill on August
31, 1994 from Hemmaraj and as required by the land purchase agreement, must use
the land in accordance with IEAT regulations.
 
    Under Thai law, a mortgage will not be valid until it is registered with the
local Land Office in which the property is located. Such a mortgage extends to
all permanent fixtures and buildings on the land but it does not accord mortgage
rights over buildings erected on the land after the date the mortgage is
registered unless so provided in the mortgage application.
 
    Another feature of Thai law requires the principal amount of the obligations
secured by mortgages to be expressed in Baht when being registered in the local
Land Office. As a result, the principal amounts secured by the mortgages (the
"Mortgaged Amounts") in the land and buildings comprising the Mill granted as
security for the Company's obligations under the Guaranties, along with other
collateral denominated in Baht, could decrease in terms of U.S.$ in the event of
a depreciation in the value of the Baht in relation to the U.S.$.
 
    In order to mitigate this risk, each mortgage has been registered in a
principal amount expressed in Baht that is based on an exchange rate of Baht to
U.S.$ of Baht 75 to U.S.$1.00. As the actual exchange rate as quoted by the Bank
of Thailand at the close of business on March 12, 1998 was Baht 41.4 to
U.S.$1.00, the use of this rate is designed to allow for a substantial decrease
in the value of the Baht without affecting the integrity of the security
provided by the mortgages. To provide further protection, each mortgage also
provides that the Company is required to increase the Mortgaged Amounts from
time to time in respect of each mortgage at its own expense in order to maintain
a Mortgaged Amount based on an exchange rate of Baht to U.S.$ that is no less
than Baht 15 per U.S.$1.00 higher than the actual exchange rate quoted at the
close of business on any business day by the Bank of Thailand. The mortgages
provide that this obligation of the Company will be triggered if, at any time,
the exchange rate of Baht to U.S.$ upon which the Mortgaged Amounts are then
based does not exceed the actual exchange rate quoted by the Bank of Thailand by
at least Baht 10 per U.S.$1.00.
 
    A mortgage of land can be enforced in Thailand only upon order of a court
judgment and sale at a public auction, unless (i) interest has been unpaid for
five years or more, (ii) the mortgagor cannot satisfy the court that the value
of the property exceeds the amount due, and (iii) there are no other mortgages
or preferential rights registered on the same property, in which case,
foreclosure is possible. Under Thai law, each secured creditor must be
registered as a "mortgagee" in order to enforce their security interest in the
mortgaged property. Normally, an agent such as the Collateral Agent would not
have standing in a Thai court to enforce a mortgage collectively on behalf of
all holders of the Securities since at the time of the Offerings the Collateral
Agent would not be the official registered holder of the Securities.
 
    To enable the holders of the Securities to enforce their security interests
in the Collateral in compliance with Thai law, an arrangement has been effected,
whereby the Collateral Agent will become the record owner of the Securities for
enforcement purposes should enforcement of the mortgage of the Company's assets
in Thailand become necessary. However, there can be no assurance that a Thai
court will recognize the Collateral Agent as having standing to enforce the
mortgages comprising the Collateral on behalf of the holders of the Securities.
See "--Enforcement of Collateral;" "Risk Factors--No Assurance of Adequate
Collateral; Ability to Realize on Collateral" "--Book-Entry Interests;
Dependence on Intermediaries."
 
                                      140

SECURITY RIGHTS IN MACHINERY AND EQUIPMENT
 
    Under Thai law, machinery that has been registered pursuant to the Machinery
Registration Act (the "Act") may be mortgaged to secure a debt ("Registerable
Machinery"). According to the Act, such a mortgage may only be registered after
the import and installation of the machinery and after registration of ownership
under the Act. Enforcement of a machinery mortgage involves the same procedures
as a land mortgage, i.e., a court judgment and public auction, unless for
example interest has been unpaid for 5 years or more, in which case, foreclosure
is possible. Under Thai practice, as is the case with mortgages of land and
buildings, each secured creditor must be registered as a "mortgagee".
 
    As of the Issue Date, no machinery of the Company has been registered
pursuant to the Machinery Registration Act. This is because final acceptance of
the machinery by the Company will not occur by such date. As soon as the
machinery is accepted in accordance with the Machinery Registration Act, they
will be examined by an official of IEAT. At that point, the Company will
register the machinery with the relevant authority. In the interim and for
machinery that is not eligible as Registrable Machinery, a security interest in
such machinery, equipment and construction material located at the Mill shall be
granted by the Company pursuant to a pledge in favor of the Book-Entry
Depositary. Under the Security Sharing Agreement, the Company is obligated to
(i) register all Registrable Machinery at the Mill and (ii) cause the existing
pledge of machinery to be converted to a mortgage registered in favor of the
holders of Senior Indebtedness and the Debentures.
 
    Thai law requires the principal amount of the obligations secured by
mortgages to be expressed in Baht when being registered with the appropriate
Thai authorities. As a result, the Mortgaged Amounts in all of the machinery and
equipment of the Company granted as security for the Company's obligations under
the Guaranties, along with other collateral denominated in Baht, could decrease
in terms of U.S.$ dollars in the event of a depreciation in the value of the
Baht in relation to the U.S.$.
 
    In order to mitigate this risk, the mortgages will be registered in
principal amounts expressed in Baht that are based on the exchange rate, and
also have the benefit of the adjustment mechanism, described above under the
caption "--Security Rights in Land and Buildings".
 
    To enable the holders of the Securities to enforce their security interests
in the Collateral in compliance with Thai law, an arrangement will be effected,
on the Issue Date, whereby the Collateral Agent will become the record owner of
the Securities for enforcement purposes should enforcement of the mortgage of
the Company's assets in Thailand become necessary. However, there can be no
assurance that a Thai court will recognize the Collateral Agent as having
standing to enforce the mortgages comprising the Collateral on behalf of the
holders of the Securities. See "--Enforcement of Collateral;" "Risk Factors--No
Assurance of Adequate Collateral; Ability to Realize on Collateral"
"--Book-Entry Interests; Dependence on Intermediaries."
 
    Under Thai law, a pledge requires satisfaction of elements prescribed in the
CCC, including a pledge of "specific goods" and possession of the goods in the
pledgee or third party.
 
SECURITY INTEREST IN INSURANCE
 
    The Company has assigned all insurance policies to the parties to the Bank
Credit Facility and the Collateral Agent (the "Insurance Assignment"). The
Insurance Assignment provides that, immediately upon the effectiveness of the
Insurance Assignment or upon the issuance to the Company of additional insurance
policies or reinsurance relating thereto with respect to the property covered by
(or to be covered by) such insurance ("Additional Insurance"), the Company will
give to or obtain from each insurer, broker, underwriter and reinsurer that is a
party to any insurance policies relating to the Collateral (the "Proceeds
Collateral") a formal notice and/or written approval or acknowledgment that the
assignment of the Proceeds Collateral has been made to the Collateral Agent and
will, promptly, but not later than 90 days after the date of the Insurance
Assignment, or, in the case of Additional Insurance which is issued after the
date of the Insurance Assignment, promptly, but not later than 90 days after the
date of the issue of such
 
                                      141

Additional Insurance, obtain and furnish to the Collateral Agent an
acknowledgment or approval of such insurer, broker, underwriter or reinsurer
written and signed on each such insurance policy.
 
    The Company also agreed to comply with the terms of each such insurance
policy, including timely payment of all insurance premiums required thereunder.
 
    All insurance proceeds received in respect of an involuntary loss and which
event is a collateral disposition shall be deposited into the Revenue Account in
accordance with the provisions under "-- Security Sharing Agreement--Proceeds
Received Under the Security Documents."
 
    In Thailand, there is no system of registration of security interests by way
of an assignment. In addition, an assignment of rights is not effective under
Thai law against a third party obligor until either notice of the assignment is
given to the obligor or written acknowledgment of the assignment is received
from the obligor.
 
ASSIGNMENT AND PLEDGE OF ACCOUNTS
 
    The Company entered into arrangements with the Collateral Agent to
establish, INTER ALIA, the Notes DSR Account, the Offshore Revenue Account, the
Notes Sinking Fund Account, the Revenue Account and the Operating Account, and
to establish the Collateral Agent's rights and obligations with respect thereto.
In addition, the Company granted a security interest in all amounts deposited in
the Company's bank accounts (the "Accounts"). The security interest will be a
perfected security interest only upon formal notice to, or written
acknowledgment by, the bank in which the account is held. Initially, the
Accounts will be held with the Collateral Agent and a perfected security
interest will be established. The Company has the right under the Indentures to
establish sub-accounts or additional accounts to form part of the Accounts,
PROVIDED that the Collateral Agent receives an opinion of counsel from the
Company in form acceptable to the Collateral Agent such that a perfected
security interest over any such account has been established in favor of the
registered holder of Securities prior to any funds being deposited therein.
Unless otherwise provided in the Indentures, the Company is authorized to
continue to control investment decisions with respect to the funds in the
Accounts until a Notice of Actionable Default has been issued by the Trustee or
the Facility Agent under the Bank Credit Facility. At such time, the Collateral
Agent is authorized to control investment decisions with respect to funds in the
Accounts and realize upon its security interest.
 
    There is no registration process with respect to the security interest in
the Accounts and, if multiple security interests are granted over the same
account, the security interest granted first in time will have priority. Except
as otherwise contemplated by the Security Documents, the failure of either the
assignment or pledge of the Accounts to constitute a first priority lien on the
Accounts at any time constitutes an Event of Default. In addition, an assignment
of rights is not effective, under Thai law, against a third party obligor until
either notice of the assignment is given to the obligor or written
acknowledgment of the assignment is received from the obligor.
 
PLEDGE OF PERMITTED INVESTMENTS
 
    Prior to the first time the Company makes a Permitted Investment described
under "Description of Notes and Guaranties--Certain Covenants--Limitations on
Restricted Payments", the Company agrees to grant security interests, by way of
pledges executed in favor of the Collateral Agent, in all amounts invested in
Permitted Investments. The security interest will be a perfected security
interest only upon formal notice to, or written acknowledgment by, the bank in
which the account is held. Unless otherwise provided in the Indentures, the
Company is authorized to continue to control investment decisions with respect
to Permitted Investments until a Notice of Actionable Default has been issued by
the Trustee. At such time the Collateral Agent is authorized to control
investment decisions with respect to funds in Permitted Investments and realize
upon its security interest.
 
                                      142

PLEDGE OF SHARES
 
    The Securities are secured by a pledge of all issued and outstanding shares
of NSM (Del). The pledge agreement grants a security interest in the capital
stock of NSM (Del) in favor of the Trustee. The pledge agreement is governed by
New York State law.
 
    The Guaranties are secured by the Collateral, including a pledge of all
issued and outstanding shares of NSM Cayman. The pledge agreement grants a
security interest in the capital stock of NSM Cayman in favor of the Collateral
Agent. The pledge agreement is governed by the laws of Cayman Islands.
 
ASSIGNMENT OF PERFORMANCE BONDS
 
    Under the Bank Credit Facility, the Lenders agreed to release their existing
security interests in five different performance bonds (the "Performance Bonds")
which have been assigned to secure the Company's right to receive payments or
damages arising in connection with certain supply contracts. The Company, the
Collateral Agent and the Lenders entered into a new separate assignment
arrangement whereby (i) the Company assigned all of its interests under the
Performance Bonds to the Collateral Agent and (ii) the Lenders share such
Collateral on a pari passu basis as per the terms of the Security Sharing
Agreement.
 
    As noted previously, in Thailand there is no system of registration of
security interests by way of an assignment. In addition, an assignment of rights
is not effective, under Thai law, against a third party obligor until either
notice of the assignment is given to the obligor or written acknowledgement of
the assignment is received from the obligor.
 
CONDITIONAL ASSIGNMENT OF PROJECT DOCUMENTS
 
    The Company conditionally assigned all rights, title and interest in and to
the Project Documents related to the construction of the Mill and conditionally
transfer all of its obligations under the Project Documents to the parties to
the Bank Credit Facility and the Collateral Agent (the "Conditional Assignment
of the Project Documents"). The Conditional Assignment of the Project Documents
provides that when the conditional assignment becomes effective, the Thai
Facility Agent and the Collateral Agent may substitute its designee as a party
to the Project Documents in place of the Company.
 
    The conditional assignment shall become effective upon receipt by the
Collateral Agent of a notice of an event of default under the Bank Credit
Facility and the Indentures.
 
SECURITY SHARING AGREEMENT
 
    The Trustee and the Collateral Agent, on behalf of the holders of the Notes,
the representative of the holders of the Debentures, on behalf of such holders,
and the facility agent (the "Facility Agent") on behalf of the lenders under the
Bank Credit Facility (the Trustee, the Collateral Agent, the Book-Entry
Depositary and the Facility Agent, the "Secured Parties"), and the Company
entered into the Security Sharing Agreement. The Security Sharing Agreement
governed the rights of the Secured Parties with respect to the Collateral,
including the right to direct remedies upon Default.
 
    In order to preserve the priority of the mortgage interests granted to the
holders of the Senior Notes and the Senior Subordinated Notes and the creditors
under the Bank Credit Facility over the second priority mortgage interests
granted to the holders of the Debentures, the Security Sharing Agreement
provides that, in the event the Company is required to effect the Mortgaged
Amounts Adjustment, the interests of the holders of the Senior Notes and the
Senior Subordinated Notes and the creditors under the Bank Credit Facility in
the Mortgaged Amounts resulting from such Mortgage Amounts Adjustment shall
remain and be made prior to the interests of the holders of the Debentures under
the mortgages securing the obligations under the Debentures. Including with
respect to their interests in any such increase (and the Company shall be
required from time to time to execute and deliver any instruments or agreements
as may be reasonably necessary or desirable to confirm the same).
 
                                      143

    The Security Sharing Agreement is governed by, and will be construed in
accordance with, Thai law, provided that the Collateral Agent's immunities and
standard of care is governed by New York law. Certain terms used in the Security
Sharing Agreement are defined below.
 
CERTAIN DEFINITIONS
 
    The following are definitions of certain terms used in the Security Sharing
Agreement:
 
    "Actionable Default" means (i) any Event of Default for the Securities under
and as defined in the Indentures or (ii) any event of default under and as
defined in the Bank Credit Facility, PROVIDED that only those events which give
the applicable secured creditor the right to accelerate indebtedness or result
in the automatic acceleration of Indebtedness, including after notice or passage
of time or both, shall be an Actionable Default.
 
    "Credit Documents" shall mean the Security Sharing Agreement, the Bank
Credit Facility, the Indentures, the purchase agreement in respect of the
Debentures, the Notes, the Debentures and the Security Documents.
 
    "Mortgaged Amounts" means the principal amount, expressed in Thai Baht, of
each of the Mortgages. At the Closing Date, the Mortgage Amounts will be set at
an amount equal to the sum of the Secured Indebtedness secured thereby expressed
in US$ converted to Baht at a rate of Baht 75 to U.S.$1.00.
 
    "Mortgaged Amounts Adjustment" means the obligation of the Company to cause
the Mortgaged Amounts to be increased from time to time at its own expense in
order to maintain at all applicable times a Mortgaged Amount based on an
exchange rate of Baht to U.S.$ (the "Mortgage Conversion Rate") that is no less
than Baht 15 per U.S.$1.00 higher than, i.e., the number of Baht per U.S.$1.00
exceeds by 15 Baht or more the number of Baht per U.S.$1.00 in, the actual
exchange rate (the "Current Exchange Rate") quoted at the close of business on
any business day by the Bank of Thailand (by way of example, if the Current
Exchange Rate is Baht 65 per U.S.$1.00, the Company would be obliged, subject to
the proviso below, to cause the Mortgaged Amounts to be increased to an amount
(expressed in Baht) equal to the Secured Indebtedness secured thereby (expressed
in U.S.$) converted to Baht at a rate of Baht 80 to U.S.$1.00), PROVIDED that
the Company shall undertake the adjustment described herein only at such times
that the Mortgage Conversion Rate does not exceed the Current Exchange Rate at
such time by at least Baht 10 per U.S.$1.00.
 
    "Mortgages" means the Land Mortgages and the Machinery Mortgages.
 
    "Notice of Actionable Default" means a notice delivered to the Collateral
Agent stating that an Actionable Default has occurred, which describes with
reasonable particularity the nature of the Actionable Default and is delivered
to the Collateral Agent by (i) the Trustee for the holders of the Notes, acting
pursuant to the Indentures, (ii) the representative of the holders of the
Debentures or (iii) the Facility Agent (as defined in the Security Sharing
Agreement), acting upon the instructions of the holders of a majority of the
Outstanding Existing Indebtedness Obligations under the Bank Credit Facility. A
notice of Actionable Default shall be deemed to have been given when the notice
referred to in the preceding sentence has actually been received by a
Responsible Officer (as defined in the Security Sharing Agreement) of the
Collateral Agent. A notice of Actionable Default shall be deemed to be
outstanding at all times after such notice was given until the earlier of such
time, if any, as (i) the Collateral Agent has been notified by the Trustee or
the Facility Agent, as the case may be, which delivered such notice, that such
notice has been rescinded or waived or (ii) the Trustee and the Facility Agent,
if any, have determined, in accordance with the provisions described under
"--Exercise of Remedies under the Security Documents," to rescind or waive such
notice.
 
                                      144

    "Outstanding Debentures Obligations" generally refer to the sum of (i) the
aggregate principal amount owed to the holders of Debentures at such time and
the aggregate amount of accrued and unpaid interest thereon at such time and
(ii) the aggregate amount of all monetary obligations of the Company and the
Note Issuers that are accrued and owing at such time to the holders of
Debentures, including compensation, indemnification and expense reimbursement
obligations and premium and Additional Amounts, if any. From and after the
delivery of a Notice of Actionable Default that is outstanding pursuant to the
Security Sharing Agreement, such amounts shall be calculated with respect to
amounts due and owing under the Debenture Guaranty, if greater than amounts due
and owing under the Debentures, from and after the delivery of a Notice of
Actionable Default.
 
    "Outstanding Existing Indebtedness Obligations" means, at any time, (i) the
aggregate principal amount owed to the holders of the Bank Credit Facility at
such time and the aggregate amount of accrued and unpaid interest thereon at
such time and (ii) the aggregate amount of all other monetary obligations of the
Company and the Note Issuers that are accrued and owing at such time to the
holders of the Bank Credit Facility, including compensation, indemnification and
expense reimbursement obligations and premium and additional amounts, if any.
 
    "Outstanding Notes Obligations" generally refer to the sum of (i) the
aggregate principal amount owed to the holders of Notes at such time and the
aggregate amount of accrued and unpaid interest thereon at such time and (ii)
the aggregate amount of all monetary obligations of the Company and the Note
Issuers that are accrued and owing at such time to the Trustee or the holders of
Notes, including compensation, indemnification and expense reimbursement
obligations and premium and Additional Amounts, if any. From and after the
delivery of a Notice of Actionable Default that is outstanding pursuant to the
Security Sharing Agreement, such amounts shall be calculated with respect to
amounts due and owing under the Guaranties, if greater than amounts due and
owing under the Notes, from and after the delivery of a Notice of Actionable
Default.
 
    "Total Secured Indebtedness" means without duplication, at any time, the sum
of (i) the Outstanding Notes Obligations at such time, (ii) the Outstanding
Existing Indebtedness Obligations at such time and (iii) the Outstanding
Debentures Obligations at such time.
 
ENFORCEMENT OF COLLATERAL
 
    The Security Documents provide that the Collateral Agent will act at the
direction of the holders of more than 50% of the outstanding principal amount of
the Notes and Debentures (or, for purposes of enforcement of remedies, 50% of
the Notes and Debentures that have been declared due and payable) with respect
to (i) the pledge of the shares of NSM (Del) or NSM Cayman and (ii) the Offshore
Reserve Account and the Notes DSR Account (in each case, the "Notes Required
Holders"); PROVIDED that if an Event of Default exists thereunder as a result of
a payment default or pursuant to the bankruptcy provision and 60 days have
elapsed with any such default remaining unremedied, then the Notes Required
Holders shall consist of those holders with more than 33 1/3% of the outstanding
principal of the Notes with the 33 1/3% number to be reduced to 10% if any such
default remains unremedied for another 30 days with the 10% number to be further
reduced to 5% if any such default remains unremedied for another 60 days;
PROVIDED FURTHER that, for purposes of such calculation, Outstanding Debentures
Obligations shall be deemed to equal zero during any period where a default
exists under the Senior Note Indenture or the Senior Subordinated Note
Indenture.
 
    With respect to the Collateral to be shared on a PARI PASSU basis with the
parties to the Bank Credit Facility, the Security Sharing Agreement provides
that the Collateral Agent will act at the direction of the holders of more than
50% of the Total Secured Indebtedness (the "Required Holders"); PROVIDED that if
an Actionable Default exists and 60 days have elapsed with any such default
remaining unremedied, then the Required Holders shall consist of those holders
with more than 33 1/3% of the Total Secured Indebtedness,
 
                                      145

with the 33 1/3% number to be reduced to 10% if any such default remains
unremedied for another 30 days with the 10% number to be further reduced to 5%
if any such default remains unremedied for another 60 days; PROVIDED FURTHER
that, for purposes of such calculation, Outstanding Debentures Obligations shall
be deemed to equal zero during any period where a default exists under the
Senior Note Indenture or the Senior Subordinated Note Indenture or the Bank
Credit Facility.
 
    Notwithstanding the preceding two paragraphs, at all times that a Default
has occurred and is continuing under the Senior Note Indenture, the holders of
the Senior Subordinated Notes shall (a) absent the consent of the holders of a
majority of the aggregate principal amount of Senior Notes outstanding, refrain
from taking any action toward collection of or enforcement or otherwise exercise
any rights of such holders of Senior Subordinated Notes with respect to the
Pledged NSM Stock or the Collateral, whether pursuant to applicable law,
contract or otherwise, including any and all rights concerning foreclosure upon
the Pledged NSM Stock or the Collateral and (b) shall (i) with respect to any
bankruptcy, insolvency, or similar proceeding, not be entitled to vote with
respect to the Pledged NSM Stock or the Collateral or their rights with respect
thereto, whether pursuant to applicable law (including applicable bankruptcy or
insolvency law), contract (including the Senior Subordinated Indenture), or
otherwise, and (ii) in connection with any vote in respect of the Pledged NSM
Stock or Collateral (including in any bankruptcy, insolvency or similar
proceeding or otherwise), be deemed to have voted in the same manner and to the
same effect as the holders of a majority of the aggregate principal amount of
Senior Notes then outstanding and the holders of the Senior Subordinated Notes
shall assign pursuant to the Security Sharing Agreement such rights to vote to
the holders of the Senior Notes for the duration of any such Default for the
purposes of effecting any such vote; PROVIDED, that the foregoing provisions (A)
will only apply to the holders of the Senior Subordinated Notes so long as the
amount owed to the holders of the Senior Notes exceeds $50 million and (B) will
not create any contractual obligation on holders of the Senior Notes to take or
refrain from taking any action in respect of the Collateral.
 
    Upon collecting the funds raised from the sale of the shared Collateral, the
Collateral Agent will be required to distribute such proceeds in accordance with
the Security Sharing Agreement. All proceeds shall be distributed to the Secured
Creditors ratably in the proportion that the outstanding Indebtedness owed each
Secured Creditor bears to the Total Secured Indebtedness; PROVIDED, HOWEVER,
that no proceeds shall be distributed to any holder of Debentures until the
Outstanding Notes Obligations and Outstanding Existing Indebtedness Obligations
have been paid in full and discharged.
 
    Under Thai law, the enforcement of a security interest in a mortgage,
whether it be land and buildings or registered machinery, must be effected by
the registered holder of the Note. Only registered secured creditors would be
recognized with standing to enforce a mortgage in a Thai court. To enforce a
mortgage in Thailand, the mortgagee must first issue a notice to the debtor
giving them a reasonable time to satisfy the debt. In the event the debt cannot
be repaid within this timeframe, the mortgagee may file an action in a court
with jurisdiction over the location where the mortgage has been registered
seeking to declare the debtor in default and order the collateral to be sold at
public auction. Once an order is obtained, the court will order a public auction
to be held at which time the property will be sold to the highest bidder.
 
    In the event an action based on the collateral were commenced in a court of
the United States, it is likely that such court would grant judgment only in
U.S.$ even though a substantial portion of the collateral is denominated in a
currency other than U.S.$. It is not clear, however, whether, in granting such
judgment, the role of conversion into U.S.$ would be determined with reference
to the date of default, the date judgment is rendered or some other date.
Holders of Notes would bear the risk of exchange rate fluctuations between the
time the amount of the judgment is calculated and the time the Holder receives
any payment on such judgment in U.S.$.
 
    In the event of bankruptcy of the Company, secured creditors have the option
whether to join in the bankruptcy proceedings. They may join the bankruptcy
proceedings subject to the conditions in Section 96
 
                                      146

of the Bankruptcy Act which allow a secured creditor to claim for the balance of
the indebtedness after enforcing its claim against the property or deducting the
value of the property given as security. They may enforce their security as
provided in Section 95 of the Bankruptcy Act in which case they need not join
the bankruptcy proceedings.
 
    For purposes of the Bankruptcy Act, "security" is defined in Section 6 to
include mortgages, pledges, rights of retention and any preferential rights
which have the same rights as a pledge.
 
    An assignment does not fall within the definition of "security". The effect
of an assignment is similar to that of a transfer of ownership, in that it may
remove property from the estate of a debtor. Assignments and giving of security
may be subject to revocation under the preference provisions in Sections 113 to
115 of the Bankruptcy Act (cancellation of fraudulent acts, and 3-year and
3-month preference provisions), and the provisions of Section 237 of the CCC
(cancellation of fraudulent acts).
 
PROCEEDS RECEIVED UNDER THE SECURITY DOCUMENTS
 
    The Collateral Agent has established and shall maintain at one or more of
its principal banking offices accounts for the benefit of all holders of Secured
Indebtedness (the "Collateral Accounts").
 
    Except as otherwise explicitly provided in any Security Document or as
otherwise set forth in the Indentures and Security Sharing Agreement, the
Collateral Agent shall deposit into the Collateral Accounts all amounts received
by it in its capacity as Collateral Agent (and not in any other capacity) in
respect of the Collateral or under the Security Documents, including all monies
received on account of any sale of or other realization upon any of the
Collateral pursuant to any Security Document or upon any Collateral Disposition
or otherwise. All proceeds shall be distributed to the Secured Creditors ratably
in the proportion that the outstanding Indebtedness owed each Secured Creditor
bears to the Total Secured Indebtedness; PROVIDED, HOWEVER, that no proceeds
shall be distributed to any holder of Debentures until the Outstanding Notes
Obligations and Outstanding Existing Indebtedness Obligations have been paid in
full and discharged. To the extent not reimbursed by the Company or the Note
Issuers, and subject to certain provisions of the Indentures, the Collateral
Agent shall have the right at any time and from time to time to apply certain
amounts in the Collateral Accounts to the payment of (i) fees, (ii) reasonable
out-of-pocket costs and expenses (including attorney fees and disbursements)
incurred by the Collateral Agent (a) in administering and carrying out its
obligations under the Security Sharing Agreement or any of the Security
Documents, (b) in exercising or attempting to exercise any right or remedy under
the Security Sharing Agreement or any of the Security Documents or (c) in taking
possession of, protecting, preserving or disposing of any item of Collateral,
including tax Liens and enforcement costs, and (iii) all amounts against or for
which the Collateral Agent is to be indemnified or reimbursed under the Security
Sharing Agreement (excluding any such costs, expenses or amounts which have
therefore been reimbursed) until all of such costs, expenses and amounts have
been paid in full.
 
    If no Notice of Actionable Default is outstanding, amounts deposited in the
Collateral Accounts may be released to the Company or the Note Issuers or paid
to the Trustee in accordance with the Indentures and upon the written
instruction of the Trustee. If a foreclosure event has occurred, amounts
deposited or on deposit in the Collateral Accounts shall be applied in the
following order of priority:
 
    FIRST, to the Collateral Agent for amounts owing to it for fees, expenses
and indemnities, then to the Trustee for payment of all Outstanding Notes
Obligations that consist of fees, expenses and indemnities incurred in
connection with the administration of the Indentures and to the Facility Agent
for payment of all Outstanding Existing Indebtedness Obligations that consists
of fees, expenses and indemnities incurred in connection with the administration
of the Bank Credit Facility;
 
                                      147

    SECOND, to the Trustee and the Facility Agent ratably in the proportion that
the outstanding Indebtedness owed each bears to the Total Secured Indebtedness;
and
 
    THIRD, the balance, if any, and only if the Outstanding Notes Obligations
and Outstanding Existing Indebtedness Obligations have been paid in full, to the
holders of the Debentures if there are any Outstanding Debenture Obligations, or
otherwise, to the Company.
 
    Under the Security Sharing Agreement, a successor Collateral Agent may be
appointed upon approval of the Company, the Trustee and a majority of the
lenders under the Bank Credit Facility (it being understood that such approval,
in each case, shall not be unreasonably withheld, including in the event that
the standing of the Collateral Agent to bring an enforcement action is not
recognized by a Thai court). Such successor Collateral Agent is required to be a
bank with an office in Bangkok, Thailand, having combined capital and surplus
equivalent to at least U.S.$50.0 million and authorized to perform the functions
of the Collateral Agent under the Security Sharing Agreement.
 
    The Security Sharing Agreement contains customary provisions with respect to
the appointment and authorization of, and the rights and duties of, the
Collateral Agent.
 
AMENDMENT OF THE SECURITY SHARING AGREEMENT AND THE SECURITY DOCUMENTS
 
    No modification, waiver or amendment of any provision of any Security
Document shall in any event be effective unless the same shall be in writing and
signed by the Trustee or Book-Entry Depositary on behalf of the holders of the
Notes, the holders of a majority of the outstanding principal balance of the
Bank Credit Facility, the Collateral Agent, the Company and the Note Issuers;
PROVIDED, HOWEVER, that (i) no such modification, waiver or amendment shall
adversely affect any of the Collateral Agent's rights, immunities or rights to
indemnification under the Security Sharing Agreement or any Security Document or
expand its duties or obligations under the Security Sharing Agreement or any
Security Document without the prior written consent of the Collateral Agent,
(ii) certain provisions related to the release of Collateral may not be
modified, amended or waived without the prior written consent of the
representatives of the Secured Parties (other than the holders of the
Debentures), (iii) no such modification, waiver or amendment shall (A) change
the provisions discussed in this paragraph "--Amendment of the Security Sharing
Agreement and the Security Documents" or certain provisions discussed under
"--Proceeds Received Under the Security Documents," certain provisions discussed
under "Enforcement of Collateral" and other provisions related to surrender of
Collateral and certain payments, the release of or termination of Liens on all
or substantially all of the Collateral, and successors and assigns and the
acceleration of Indebtedness, in each case, without the prior written consent of
the holders of the Senior Indebtedness or (B) (except to the extent otherwise
set forth in or prohibited by the Security Documents) create any Lien on the
Collateral or any part thereof or terminate any part of the Liens of the
Collateral Agent on the Collateral or deprive the holders of any part of the
security afforded by the Liens of the Security Sharing Agreement or the Security
Documents without the consent of representatives of the Secured Creditors of
outstanding obligation and (iv) no such modification, waiver or amendment shall
deprive the holder of the Debentures of their rights under the Security Sharing
Agreement without the consent of a majority of the holders of Outstanding
Debentures Obligations.

                               TAX CONSIDERATIONS
 
UNITED STATES FEDERAL INCOME TAXATION
 
    The following is a description of the principal U.S. federal income tax
consequences of the exchange of the Old Securities for the New Securities. In
the opinion of White & Case LLP, special tax counsel to the Company, this
description applies only to Securities held as capital assets and does not
address aspects of U.S. federal income taxation that may be applicable to
holders that are subject to special tax rules, such as insurance companies,
tax-exempt organizations, banks or dealers or traders in securities or
currencies or to holders that will hold Securities as part of a position in a
"straddle" or as part of a "hedging", "conversion" or "integrated" transaction
for U.S. federal income tax purposes or that have a "functional currency" other
than the U.S.. In addition, the summary, does not consider the effect of any
foreign, state, local, gift, estate or other tax laws that may be applicable to
a particular investor. Each prospective purchaser should consult its tax advisor
with respect to the U.S. federal, state, local and foreign tax consequences of
exchanging Old Securities for the New Securities.
 
    For purposes of this summary, a "U.S. Holder" is a holder of Securities who,
for U.S. federal income tax purposes, is (i) a citizen or resident of the United
States, (ii) a corporation or partnership organized in or under the laws of the
United States or any state thereof (including the District of Columbia), (iii)
an estate the income of which is subject to U.S. federal income taxation
regardless of its source; or (iv) a trust (a) the administration over which a
United States court can exercise primary supervision and (b) all of the
substantial decisions of which one or more United States persons have the
authority to control. Notwithstanding the preceding sentence, to the extent
provided in Treasury Regulations, certain trusts in existence on August 20,
1996, and treated as United States persons prior to such date, that elect to
continue to be treated as United States persons will also be a U.S. Holder.
 
    This summary is based on the Internal Revenue Code of 1986, as amended,
existing and proposed Treasury Regulations, administrative pronouncements and
judicial decisions, each as in effect and available on the date hereof. All of
the foregoing are subject to change (possibly with retroactive effect) or
differing interpretations which could affect the tax consequences described
herein.
 
TAX TREATMENT OF THE EXCHANGE OFFERS
 
    The exchange of Securities by a holder for an New Securities pursuant to the
Exchange Offers will not constitute a taxable exchange for U.S. federal income
tax purposes. A holder will not recognize gain or loss upon the receipt of New
Securities pursuant to the Exchange Offers and a U.S. Holder will be required to
continue to include interest (including original issue discount) on the New
Securities in gross income for U.S. federal income tax purposes in the manner
and to the extent such income was includible under the Securities. A holder's
holding period for New Securities will include the holding period for the Notes
exchanged pursuant to the Exchange Offers and such holder's adjusted basis in
New Securities will be the same as such holder's adjusted basis in such Notes.
 
    THE ABOVE DESCRIPTION IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF
ALL TAX CONSEQUENCES RELATING TO THE EXCHANGE OF OLD SECURITIES FOR NEW
SECURITIES. HOLDERS OF SECURITIES SHOULD CONSULT THEIR OWN TAX ADVISORS
CONCERNING THE TAX CONSEQUENCES OF THEIR PARTICULAR SITUATIONS.
 
                                 THAI TAXATION

TAX TREATMENT OF NOTES
 
    Thai withholding tax would be payable by withholding in respect of payments
under or with respect to the Securities if interest on the Securities were to
paid by or on behalf of the Company from or in Thailand. Although there have
been no precedent Thailand Revenue Rulings on the point, the Company believes,
upon consultation with the competent authorities, that discounts on the
Securities are not subject to withholding tax at the time of issue. Such
discounts will be subject to withholding tax at the rate of 15% at maturity or
when the Notes are redeemed. Payment of interest by the Note Issuers to the
holders of the Notes is not subject to Thai withholding tax. Payments by the
Company to the Note Issuers to fund interest payment obligations on the
Securities may be subject to withholding tax at the rate of 15%. While the
Company intends to structure its interest payments to the Note Issuers to
substantially reduce the effect of such withholding, there can be no assurance
that such measures will prove successful in reducing the application of
withholding taxes. The Company is seeking a favorable opinion of the Thai
Revenue Department for this structure. See "Risk Factors--Withholding Tax" If a
Note Issuer or the Company is required by law to make any such deduction or
withholding, it will pay Additional Amounts as may be necessary so that every
net payment of the principal of and interest on the Notes paid to the holder
thereof will not be less than the amount provided for in such Notes to be then
due and payable, subject to certain exceptions and limitations set forth above
(see "Description of Notes and Guaranties -- Additional Amounts"). The rate of
Thai withholding tax on interest and, when redeemed, discount is normally 15%
(reduced to 10% where the payee is a financial institution incorporated in a
jurisdiction having a tax treaty with Thailand and has no permanent
establishment in Thailand).
 
                            CAYMAN ISLANDS TAXATION
 
    The Cayman Islands currently have no foreign exchange control restrictions
and no income, corporate or capital gains tax, estate duty, inheritance tax,
gift tax or withholding tax applicable to NSM Cayman or any holder of
Securities. Accordingly, payment of principal of (including any premium) and
interest on, and any transfer or exchange of, the Notes will not be subject to
taxation in the Cayman Islands, no Cayman Islands withholding tax will be
required on such payments to any holder of Notes and gains derived from the sale
of Securities will not be subject to Cayman Islands capital gains tax. The
Cayman Islands are not party to any double taxation treaties.
 
    NSM Cayman has obtained an undertaking from the Governor-in-Council of the
Cayman Islands that, in accordance with section 6 of the Tax Concessions Law
(1995 Revision) of the Cayman Islands, for a period of 20 years from December
30, 1997 (the date of the undertaking) no law which is enacted in the Cayman
Islands imposing any tax to be levied on profits, income, gains or appreciations
shall apply to NSM Cayman or its operations and, in addition, that no tax to be
levied on profits, income, gains or appreciations or which is in the nature of
estate duty or inheritance tax shall be payable (i) on or in respect of the
shares, debentures or other obligations of NSM Cayman or (ii) by way of the
withholding in whole or in part of a payment of dividend or other distribution
of income or capital by NSM Cayman to its members or a payment of principal or
interest or other sums due under a debenture or other obligation of NSM Cayman.
 
    No stamp duties or similar taxes or charges are payable under the laws of
the Cayman Islands in respect of the execution and issue of the New Securities
unless they are executed in or brought within (for example, for the purposes of
enforcement) the jurisdiction of the Cayman Islands, in which case stamp duty of
0.25% of the face amount thereof is payable on each New Security (up to a
maximum of 250 Cayman Islands Dollars ("C.I.$") (U.S.$305)) unless stamp duty of
C.I.$500 (U.S.$610) has been paid in respect of each tranche of New Securities.
An instrument of transfer in respect of a New Security if executed in or brought
within the jurisdiction of the Cayman Islands will attract a Cayman Islands
stamp duty of C.I.$100 (U.S.$122).

                            OLD REGISTRATION RIGHTS
 
    The Note Issuers, the Company, and the Initial Purchasers have entered into
a registration rights agreement dated March 12, 1998 (the "Registration Rights
Agreement") pursuant to which the Note Issuers and the Company have agreed, for
the benefit of the holders, that the Note Issuers will, at their own cost, (i)
within 90 days after the Issue Date, file a registration statement (the
"Exchange Offer Registration Statement") with the Commission with respect to the
Exchange Offer for notes (the "Exchange Notes") of the Note Issuers which will
have terms substantially identical in all material respects to the Notes and be
guaranteed by the Company (except that the Exchange Notes will not contain terms
with respect to transfer restrictions or interest rate increases as described
herein), (ii) use their reasonable efforts to cause the Exchange Offer
Registration Statement to be declared effective under the Securities Act within
180 days after the Issue Date and (iii) use their reasonable efforts to
consummate the Exchange Offer within 210 days after the Issue Date. Upon the
Exchange Offer Registration Statement being declared effective, the Note Issuers
will offer the Exchange Notes in exchange for surrender of the Notes. The Note
Issuers will keep the Exchange Offer open for not less than 20 business days (or
longer if required by applicable law) after the date notice of the Exchange
Offer is mailed to the holders of the Notes. For each of the Notes surrendered
pursuant to the Exchange Offer, the holder who surrendered such Note will
receive an Exchange Note having a principal amount equal to that of the
surrendered Note. Interest on each Exchange Note will accrue from the last
interest payment date on which interest was paid on the Note surrendered in
exchange therefor or, if no interest has been paid on such Note, from the Issue
Date. Under existing Commission interpretations, the Exchange Notes would be
freely transferable by holders thereof other than affiliates of the Note Issuers
after the Exchange Offer without further registration under the Securities Act
if the holder of the Exchange Notes represents that it is acquiring the Exchange
Notes in the ordinary course of business, that it has no arrangement or
understanding with any person to participate in the distribution of the Exchange
Notes and that it is not an affiliate of the Note Issuers, as such terms are
interpreted by the Commission; PROVIDED that broker-dealers ("Participating
Broker-Dealers") receiving Exchange Notes in the Exchange Offer will have a
prospectus delivery requirement with respect to resales of such Exchange Notes.
The Commission has taken the position that the Participating Broker-Dealers may
fulfill their prospectus delivery requirements with respect to the Exchange
Notes (other than a resale of an unsold allotment from the original sale of the
Notes) with the prospectus contained in the Exchange Offer Registration
Statement. The Note Issuers have agreed for a period of 180 days after
consummation of the Exchange Offer to make available a prospectus meeting
requirements of the Securities Act to Participating Broker-Dealers and other
persons, if any, with similar prospectus delivery requirements for use in
connection with any resale of such Exchange Notes.
 
    Each holder who wishes to exchange its Notes for Exchange Notes in the
Exchange Offer will be required to represent that any Exchange Notes to be
received by it will be acquired in the ordinary course of its business and that
at the time of the commencement of the Exchange Offer it has no arrangement or
understanding with any person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Notes and that it is not an
affiliate of the Note Issuers.
 
    If the holder is not a broker-dealer, it will be required to represent that
it is not engaged in, and does not intend to engage in, the distribution of the
applicable Exchange Notes. If the holder is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Notes that were acquired as a
result of market making activities or other trading activities, it will be
required to acknowledge that it will deliver a prospectus in connection with any
resale of such Exchange Notes.
 
    In the event that (i) applicable law or interpretations of the staff of the
Commission do not permit the Note Issuers to effect such an Exchange Offer, (ii)
for any other reason the Exchange Offer is not consummated within 210 days after
the Issue Date, (iii) under certain circumstances, if the Initial Purchaser
shall so request, or (iv) any holder of the Notes (other than the Initial
Purchaser or an affiliate of the Note Issuers) is not eligible to participate in
the Exchange Offer, the Note Issuers, will at their own cost, (a) as promptly as
practicable, file a shelf registration statement covering resales of the Notes
(a
 
                                      151

"Shelf Registration Statement"), (b) use their reasonable efforts to cause such
Shelf Registration Statement to be declared effective under the Securities Act
by the 245th day after the Issue Date and (c) use their reasonable efforts to
keep effective such Shelf Registration Statement until the earlier of two years
after the Issue Date and such time as all of the Notes have been sold
thereunder. The Note Issuers will, in the event of the filing of a Shelf
Registration Statement, provide to each holder of the Notes copies of the
prospectus which is a part of such Shelf Registration Statement, notify each
such holder when such Shelf Registration Statement has become effective and take
certain other actions as are required to permit unrestricted resales of the
Notes. A holder that sells its Notes pursuant to a Shelf Registration Statement
generally will be required to be named as a selling securityholder in the
related prospectus and to deliver a prospectus to purchasers, will be subject to
certain of the civil liability provisions under the Securities Act in connection
with such sales and will be bound by the provisions of the Registration Rights
Agreement which are applicable to such holder (including certain indemnification
obligations).
 
    Although the Note Issuers intend to file the registration statement
described above, there can be no assurance that such registration statement will
be filed or, if filed, that it will become effective. If the Note Issuers fail
to comply with the above provisions or if such registration statement fails to
become effective, then, as liquidated damages, additional interest (the
"Additional Interest") shall become payable with respect to the Notes as
follows:
 
        (i) if the Exchange Offer Registration Statement is not filed within 90
    days following the Issue Date, Additional Interest shall accrue on the Notes
    over and above the stated interest at a rate of .50% per annum commencing on
    the 91st day after the Issue Date and such Additional Interest rate shall
    increase by .50% per annum on the first day of each 90 day period
    thereafter;
 
        (ii) if the Exchange Offer Registration Statement is not declared
    effective within 180 days following the Issue Date or, if applicable, the
    Shelf Registration Statement is not declared effective within 245 days
    following the Issue Date, Additional Interest shall accrue on the Notes over
    and above the stated interest at a rate of .50% per annum commencing on the
    181st day after the Issue Date and such Additional Interest rate shall
    increase by .50% per annum on the first day of each 90 day period
    thereafter; or
 
        (iii) if (A) the Note Issuers have not exchanged all Notes validly
    tendered in accordance with the terms of the Exchange Offer on or prior to
    210 days after the Issue Date or (B) the Exchange Offer Registration
    Statement ceases to be effective at any time prior to the time that the
    Exchange Offer is consummated or (C) if applicable, the Shelf Registration
    Statement has been declared effective and such Shelf Registration Statement
    ceases to be effective at any time prior to the second anniversary of the
    Issue Date (unless all the Notes have been sold thereunder), then Additional
    Interest shall accrue on the Notes over and above the stated interest at a
    rate of .50% per annum commencing on (x) the 211th day after the Issue Date
    with respect to the Notes validly tendered and not exchanged by the Company,
    in the case of (A) above, or (y) the day the Exchange Offer Registration
    Statement ceases to be effective or usable for its intended purpose in the
    case of (B) above, or (z) the day such Shelf Registration Statement ceases
    to be effective in the case of (C) above and such Additional Interest rate
    shall increase by .50% per annum on the first day of each 90 day period
    thereafter; PROVIDED, HOWEVER, that the Additional Interest rate on the
    Notes may not exceed in the aggregate 1.5% per annum; and PROVIDED FURTHER,
    that (1) upon the filing of the Exchange Offer Registration Statement or
    Shelf Registration Statement (in the case of clause (i) above), (2) upon the
    effectiveness of the Exchange Offer Registration Statement or Shelf
    Registration Statement (in the case of (ii) above), or (3) upon the exchange
    of Exchange Notes for all Notes tendered (in the case of clause (iii)(A)
    above), or (4) upon the effectiveness of the Exchange Offer Registration
    Statement which had ceased to remain effective in the case of clause
    (iii)(B) above, or (5) upon the effectiveness of the Shelf Registration
    Statement which had ceased to remain effective (in the case of clause
    (iii)(C) above), Additional Interest on the Notes as a result of such clause
    (or the relevant subclause thereof), as the case may be, shall cease to
    accrue.
 
    The Note Issuers, the Company and the original purchasers of the Debentures
entered into a registration rights agreement whereby the Company agreed to
exchange the New Debentures for the Old Debentures no later than two years after
the issue Date.
 
                                      152

                              PLAN OF DISTRIBUTION
 
    Based on interpretations by the Commission set forth in no-action letters
issued to third parties, the Company believes that New Securities issued
pursuant to the Exchange Offers in exchange for the Old Securities may be
offered for resale, resold and otherwise transferred by holders thereof (other
than any holder which is (i) an "affiliate" of the Note Issuers or the Company
within the meaning of Rule 405 under the Securities Act, (ii) a broker-dealer
who acquired Securities directly from the Note Issuers or the Company or (iii)
broker-dealers who acquired Securities as a result of market-making or other
trading activities) without compliance with the registration and prospectus
delivery provisions of the Securities Act provided that such New Securities are
acquired in the ordinary course of such holders' business, and such holders are
not engaged in, and do not intend to engage in, and have no arrangement or
understanding with any person to participate in, a distribution of such New
Securities; provided that broker-dealers ("Participating Broker-Dealers")
receiving New Securities in the Exchange Offers will be subject to a prospectus
delivery requirement with respect to resales of such New Securities. To date,
the Commission has taken the position that Participating Broker-Dealers may
fulfill their prospectus delivery requirements with respect to transactions
involving an exchange of securities such as the exchange pursuant to the
Exchange Offers (other than a resale of an unsold allotment from the sale of
certain Old Securities to the Initial Purchasers) with the Prospectus, contained
in the Registration Statement. Pursuant to the Registration Rights Agreements,
the Company has agreed to permit Participating Broker-Dealers and other persons,
if any, subject to similar prospectus delivery requirements to use this
Prospectus in connection with the resale of such New Securities. The Note
Issuers and the Company have agreed that, for a period of 180 days after the
Expiration Date, it will make this Prospectus, and any amendment or supplement
to this Prospectus, available to any broker-dealer that requests such documents
in the Letter of Transmittal.
 
    Each holder of the Old Securities who wishes to exchange its Old Securities
for New Securities in the Exchange Offers will be required to make certain
representations to the Note Issuers and the Company as set forth in "The
Exchange Offer--Purpose and Effect of the Exchange Offer." In addition, each
holder who is a broker-dealer and who receives New Securities for its own
account in exchange for Old Securities that were acquired by it as a result of
market-making activities or other trading activities, will be required to
acknowledge that it will deliver a prospectus in connection with any resale by
it of such New Securities.
 
    The Company will not receive any proceeds from any sale of New Securities by
broker-dealers. New Securities received by broker-dealers for their own account
pursuant to the Exchange Offers 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 New Securities 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 and/or the purchasers of any such New Securities. Any
broker-dealer that resells New Securities that were received by it for its own
account pursuant to the Exchange Offers and any broker or dealer that
participates in a distribution of such New Securities may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of New Securities and any commissions 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.
 
    The Note Issuers have agreed to pay all expenses incidental to the Exchange
Offers other than commissions and concessions of any brokers or dealers and will
indemnify holders of the Old Securities (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act, as set
forth in the Registration Rights Agreements.

            DESCRIPTION OF NOTE DEPOSITARY AGREEMENT; DELIVERY; FORM
 
GENERAL
 
    The Old Senior Notes Old Senior Subordinated Notes and the Old Debentures
were deposited with The Chase Manhattan Bank as Book-Entry Depositary pursuant
to the terms of the Note Depositary Agreement. The Book-Entry Depositary issued
certificateless depositary interests (representing a 100% interest in the
underlying Securities offered and sold to qualified institutional buyers
("QIBs") pursuant to Rule 144A (the "Old Rule 144A Global Securities"), the
underlying Securities offered and sold to institutional "accredited investors"
(as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act ("IAIs")
who are not QIBs (the "Old IAI Global Securities" and, together with the Rule
144A Global Securities, the "Old U.S. Global Securities") and the underlying
Securities offered and sold to Non-U.S. Persons in reliance on Regulation S (the
"Old Regulation S Global Securities"), respectively) to The Depository Trust
Company ("DTC") or its nominee.
 
    The New Senior Notes New Senior Subordinated Notes and the New Debentures
will be issued in the form of one fully registered New Senior Note in global
form (the "New Global Senior Note"), one fully registered New Senior
Subordinated Note in global form (the "New Global Senior Subordinated Note") and
one fully registered New Debenture in global form (the "New Global Debenture").
The New Global Senior Note New Global Senior Subordinated Note and the New
Global Debenture are collectively referred to herein as the "New Global
Securities." The New Global Securities will be deposited with The Chase
Manhattan Bank as Book-Entry Depositary pursuant to the terms of the Note
Depositary Agreement. The Book-Entry Depositary will issue one or more
certificateless depositary interests representing a 100% interest in the New
Senior Notes and New Senior Subordinated Notes to The Depository Trust Company
("DTC") or its nominee.
 
    Upon confirmation by DTC that the Book-Entry Depositary has custody of the
New Global Securities and upon acceptance by DTC of the certificateless
depositary interest pursuant to the Letter of Representations, DTC will record
beneficial interests in the New Global Securities. Book-Entry Interests will be
recorded in denominations of $1,000 and integral multiples thereof (except for
the New Global Debentures, where such interests will be recorded in
denominations of $1.00). Ownership of Book-Entry Interests will be limited to
Persons that have accounts with DTC ("participants") or Persons that hold
interests in the Book-Entry Interests through participants ("indirect
participants"), including, as applicable, the Euroclear Operator, Cedel, banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with DTC, either directly or indirectly. Indirect participants
shall also include Persons that hold through such indirect participants. The
Book-Entry Interests will not be held in definitive form. Instead, DTC will
credit, on its book-entry registration and transfer system, the participant's
accounts with the respective interests beneficially owned by such participants.
Ownership of Book-Entry Interests will be shown on, and the transfer of these
Book-Entry Interests or the interests therein will be effected only through,
records maintained by DTC (with respect to interests of its participants) and on
the records of participants or indirect participants (with respect to interests
of indirect participants). The laws of some states may require that certain
purchasers of securities take physical delivery of such securities in definitive
form. The foregoing limitations may impair the ability to own, transfer or
pledge Book-Entry Interests.
 
    So long as the Book-Entry Depositary, or its nominee, is the Holder of the
New Global Securities underlying Book-Entry Interests, the Book-Entry Depositary
or such nominee, as the case may be, will be considered the sole legal owner and
holder of such New Senior Notes, New Senior Subordinated Notes represented by
such New Global Securities for all purposes under the Indentures and the New
Senior Notes, New Senior Subordinated Notes and New Debentures. Except as set
forth below, participants or indirect participants will not be entitled to have
Securities or Book-Entry Interests registered in their names, will not receive
or be entitled to receive physical delivery of any New Senior Notes, New Senior
Subordinated Notes or New Debenture represented thereby or such New Global
Securities or any New Senior Notes, New Senior Subordinated Notes or New
Debenture represented thereby in registered form
 
                                      154

and will not be considered the owners or holders thereof under the Indentures.
Accordingly, each Person holding a Book-Entry Interest must rely on the
procedures of the Book-Entry Depositary and DTC and, indirect participants must
rely on the procedures of the participant or indirect participants through which
such Person owns its interest in the Book-Entry Interests, including, as
applicable, the Euroclear Operator and Cedel, to exercise any rights and
obligations of the holder under the Indentures. See "--Action in Respect of the
New Global Securities and the Book-Entry Interests." If any Definitive Notes are
issued, they will only be issued in registered form.
 
    Unless and until Book-Entry Interests are exchanged for Definitive
Securities (as defined); the certificateless depositary interests held by DTC
may not be transferred except as a whole by DTC to a nominee of DTC or by a
nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to
a successor of DTC or a nominee of such successor.
 
PAYMENTS ON GLOBAL SENIOR NOTES AND GLOBAL SENIOR SUBORDINATED NOTES
 
    Payment of principal of and interest on, any other amount due in respect of,
the New Global Senior Notes, New Global Senior Subordinated Notes and the New
Dentures will be made to the Book-Entry Depositary, as the Holder thereof. All
such amounts will be payable, by a Paying Agent located outside of Thailand, in
dollars or in such other coin or currency of the United States of America as at
the time of payment is legal tender for the payment therein of public and
private debts. Upon receipt of any payment of principal of or interest on the
New Global Securities, the Book-Entry Depositary will distribute all such
payments to Cede & Co., as a nominee of DTC. All such payments will be
distributed without deduction or withholding for any taxes, duties, assessments
or other governmental charges of whatever nature except as may be required by
law. If any such deduction or withholding is required to be made, such
Additional Amounts will be paid by the Note Issuers to the Book-Entry Depositary
as may be necessary in order that the net amounts received by the holder of the
New Global Securities or owners of Book-Entry Interests after such deduction or
withholding shall be not less than the amounts specified in such New Senior Note
or New Senior Subordinated Note or New Debenture, as the case may be, to which
such holder or owner is entitled. DTC, upon receipt of any payment from the
Book-Entry Depositary, will promptly credit participants' accounts with payments
in amounts proportional to their respective ownership of Book-Entry Interests,
as shown on the records of DTC. The Note Issuers expect that payments by
participants to owners of interest in Book-Entry Interests held through such
participants or indirect participants will be governed by standing customer
instructions and customary practices, as is now the case with the securities
held for the accounts of customers in bearer form or registered in "street
name", and will be the responsibility of such participants or indirect
participants. None of the Note Issuers, the Company, the Trustee, the Book-Entry
Depositary or any other agent of the Note Issuers, the Company, the Trustee or
the Book-Entry Depositary will have any responsibility or liability for any
aspect of the records relating to or payments made on account of a participant's
ownership of Book-Entry Interests or for maintaining, supervising or reviewing
any records relating to a participant's ownership of Book-Entry Interests.
 
INFORMATION REGARDING DTC, THE EUROCLEAR OPERATOR AND CEDEL
 
    DTC, the Euroclear Operator and Cedel have advised the Note Issuers as
follows:
 
    DTC.  DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York 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 of its participants and to facilitate the
clearance and settlement of transactions among its participants in such
securities through electronic book-entry changes in accounts of the
participants, thereby eliminating the need for physical movement of securities
certificates. DTC participants include securities brokers and dealers (including
the Initial Purchasers), banks, trust companies, clearing corporations and
certain other organizations, some of whom (and/or their representatives) own
DTC.
 
                                      155

    THE EUROCLEAR OPERATOR AND CEDEL.  The Euroclear Operator and Cedel each
hold securities for their account holders and facilitate the clearance and
settlement of securities transactions by electronic book-entry transfers between
their respective account holders, thereby eliminating the need for physical
movements of certificates and any risk from lack of simultaneous transfers of
securities.
 
    The Euroclear Operator and Cedel provide various services including
safekeeping, administration, clearance and settlement of internationally traded
securities and securities lending and borrowing. The Euroclear Operator and
Cedel also deal with domestic securities markets in several countries through
established depository and custodial relationships. The Euroclear Operator and
Cedel have established an electronic bridge between their two systems across
which their respective account holders may settle trades with each other.
 
    Account holders in the Euroclear Operator and Cedel are world-wide financial
institutions including underwriters, securities brokers and dealers, banks,
trust companies and clearing corporations. Indirect access to the Euroclear
Operator and Cedel is available to other institutions that clear through or
maintain a custodial relationship with an account holder of either system.
 
    Account holder's overall contractual relations with the Euroclear Operator
and Cedel are governed by the respective rules and operating procedures of the
Euroclear Operator and Cedel and any applicable laws. The Euroclear Operator and
Cedel act under such rules and operating procedures only on behalf of their
respective account holders, and have no record of or relationship with persons
holding through their respective account holders.
 
    The Note Issuers understand that under existing industry practices, if
either the Note Issuers or Trustee requests any action of owners of Book-Entry
Interests or if an owner of a Book-Entry Interest desires to give or take any
action that a holder is entitled to give or take under the Indentures, DTC would
authorize the participants owning the relevant Book-Entry Interests to give or
take such action, and such participants would authorize indirect participants to
give or take such action or would otherwise act upon the instructions of such
indirect participants.
 
REDEMPTION
 
    In the event the New Global Securities (or a portion thereof) are redeemed,
the Book-Entry Depositary will deliver all amounts received by it in respect of
the redemption of the New Global Securities to DTC and surrender the New Global
Securities to the Trustee for cancelation. The redemption price payable in
connection with the redemption of Book-Entry Interests will be equal to the
amount received by the Book-Entry Depositary in connection with the redemption
of the New Global Securities (or portion thereof). For any redemptions of the
New Global Securities in part, selection of Book-Entry Interests to be redeemed
will be made by DTC on a pro rata basis (or on such other basis as DTC deems
fair and appropriate); PROVIDED that no Book-Entry Interests of U.S.$1,000
principal amount or less shall be redeemed in part. Once redeemed in part, a New
Global Senior Note or New Global Senior Subordinated Note, as the case may be,
in the principal amount equal to the unredeemed portion thereof will be issued
and delivered to the Book-Entry Depositary.
 
TRANSFERS AND TRANSFER RESTRICTIONS
 
    All transfers of Book-Entry Interests will be recorded in accordance with
the Book-Entry system maintained by DTC, pursuant to customary procedures
established by DTC and its participants. See "-- General". Pursuant to the Note
Depositary Agreement, the New Global Securities may be transferred only to a
successor Book-Entry Depositary.
 
ISSUANCE OF DEFINITIVE SECURITIES
 
    Holders of Book-Entry Interests will be entitled to receive definitive
Securities in registered form ("Definitive Securities") in exchange for their
holdings of Book-Entry Interests (i) if DTC is at any time unwilling or unable
to continue as, or ceases to be, a clearing agency registered under the Exchange
Act,
 
                                      156

and a successor to DTC registered as a clearing agency under the Exchange Act is
not able to be appointed by the Note Issuers within 90 days of such
notification, or (ii) if the Book-Entry Depositary is at any time unwilling or
unable to continue as Book-Entry Depositary and a successor Book-Entry
Depositary is not able to be appointed by the Note Issuers within 90 days. Any
Definitive Securities issued in exchange for Book-Entry Interests will be
registered in such name or names as the Book-Entry Depositary shall instruct the
Trustee based on the instructions of DTC. It is expected that such instructions
will be based upon directions received by DTC from participants with respect to
ownership of Book-Entry Interests.
 
    In addition to the foregoing, on or after the occurrence of an Event of
Default, holders of Book-Entry Interests will be entitled to request and receive
Definitive Securities. Such Definitive Securities will be issued to and
registered in the name of, or as directed by, such Person only upon the request
in writing by the Book-Entry Depositary (based upon the instructions of DTC).
Such a request for, and receipt of, Definitive Securities by holders of
Book-Entry Interests will increase the risks associated with the enforcement of
Collateral hereafter because Thai law would likely not recognize the standing of
such holders to foreclose upon the Collateral.
 
    To the extent permitted by law, the Note Issuers, the Company, the Trustee
and any paying agent shall be entitled to treat the Person in whose name any
Definitive Security is registered as the absolute owner thereof. The Indentures
contain provisions relating to the maintenance by a registrar of a register
reflecting ownership of Definitive Securities, if any, and any other provisions
customary for a registered debt security. Any payments in respect of a
Definitive Security will be made to the Holder appearing on the register at the
close of business on the record date at his address shown on the register.
 
TRANSFER AND EXCHANGE OF DEFINITIVE SECURITIES
 
    In the event that Definitive Securities have been issued, a holder may
transfer or exchange the Definitive Securities in accordance with the
Indentures. The Registrar and the Trustee may require a holder, among other
things, to furnish appropriate endorsements and transfer documents and the Note
Issuers may require a holder to pay any taxes and fees required by law or
permitted by the Indentures. The Note Issuers are not required to transfer or
exchange any Securities selected for redemption for a period of 15 days before a
selection of Securities to be redeemed. If Definitive Securities are issued, the
Note Issuers will appoint a Person reasonably acceptable to the Trustee, as an
additional paying and transfer agent. Upon the issuance of Definitive
Securities, holders will be able to transfer and exchange Definitive Securities
at the office of such paying and transfer agent; PROVIDED that all transfers and
exchanges must be effected in accordance with the terms of the Indentures and,
among other things, be recorded in the register maintained by the registrar.
 
ACTION IN RESPECT OF THE GLOBAL NOTES AND THE BOOK-ENTRY INTERESTS
 
    Not later than 10 days after receipt by the Book-Entry Depositary of notice
of any solicitation of consents or requests for a waiver or other action by the
holder of the New Global Securities or holders of the Book-Entry Interests, the
Book-Entry Depositary will mail to DTC a notice containing (a) such information
as is contained in such notice, (b) a statement that at the close of business on
a specified record date DTC will be entitled to instruct the Book-Entry
Depositary as to the consent, waiver or other action, if any, pertaining to the
Book-Entry Interests or the Global Securities and (c) a statement as to the
manner in which such instructions may be given. Upon the written request of DTC,
the Book-Entry Depositary shall endeavor insofar as practicable to take such
action regarding the requested consent, waiver or other action in respect of the
Book-Entry Interests or the Global Securities in accordance with any
instructions set forth in such request. DTC is expected to follow the procedures
described under "-- General" above with respect to soliciting instructions from
its participants. The Book-Entry Depositary will not exercise any discretion in
the granting of consents or waivers or the taking of any other action in respect
of the Book-Entry Interests or the Global Securities.
 
                                      157

REPORTS
 
    The Book-Entry Depositary will immediately, and in no event later than 10
days from receipt, send to DTC, a copy of any notices, reports and other
communications received relating to the Note Issuers or the Book-Entry
Interests. Copies of all such notices, reports and communications will be
available for inspection at the office of the listing agent for the Securities.
All notices regarding the Securities will be (i) published in a leading
newspaper having a general circulation in New York (which is expected to be THE
WALL STREET JOURNAL) or (ii) in the case of Definitive Securities, mailed to
Holders by first-class mail at their respective addresses as they appear on the
registration books of the Registrar.
 
ACTION BY BOOK-ENTRY DEPOSITARY
 
    Subject to certain limitations, upon the occurrence of a default with
respect to the Securities, or in connection with any other right of the holder
of the New Global Securities under the Indentures or the Note Depositary
Agreement, if requested in writing by DTC, the Book-Entry Depositary will take
any such action as shall be requested in such notice.
 
CHARGES OF BOOK-ENTRY DEPOSITARY
 
    The Note Issuers have agreed to pay all charges of the Book-Entry Depositary
under the Note Depositary Agreement. The Note Issuers have also agreed to
indemnify the Book-Entry Depositary against certain liabilities incurred by it
under the Note Depositary Agreement.
 
AMENDMENT AND TERMINATION
 
    The Note Depositary Agreement may be amended by agreement among the Note
Issuers and the Book-Entry Depositary. The consent of DTC shall not be required
in connection with any amendment to the Note Depositary Agreement: (i) to cure
any inconsistency, omission, defect or ambiguity in such Agreement; (ii) to add
to the covenants and agreements of the Book-Entry Depositary or the Note
Issuers; (iii) to effectuate the assignment of the Book-Entry Depositary's
rights and duties to a qualified successor; (iv) to comply with the Securities
Act, the Exchange Act, the U.S. Investment Company Act of 1940, as amended, or
the Trust Indenture Act of 1939; or (v) to modify, alter, amend or supplement
the Note Depositary Agreement in any other manner that is not adverse to DTC or
the holders of Book-Entry Interests. Except as set forth above, no amendment
that adversely affects DTC or the holders of Book-Entry Interests may be made to
the Note Depositary Agreement or the Book-Entry Interests without the consent of
DTC.
 
    Upon the issuance of Definitive Securities, the Note Depositary Agreement
will terminate. The Note Depositary Agreement may be terminated upon the
resignation of the Book-Entry Depositary if no successor has been appointed
within 90 days as set forth under "--Resignation or Removal of Book-Entry
Depositary" below.
 
RESIGNATION OR REMOVAL OF BOOK-ENTRY DEPOSITARY
 
    The Book-Entry Depositary may at any time resign as Book-Entry Depositary
upon 60 days' written notice delivered to each of the Note Issuers and the
Trustee. The Note Issuers may remove the Book-Entry Depositary at any time upon
90 days' written notice. No resignation or removal of the Book-Entry Depositary
and no appointment of a successor Book-Entry Depositary shall become effective
until (i) the acceptance of appointment by the successor Book-Entry Depositary
or (ii) the issuance of Definitive Securities.
 
OBLIGATION OF BOOK-ENTRY DEPOSITARY
 
    The Book-Entry Depositary will assume no obligation or liability under the
Note Depositary Agreement other than to use good faith and reasonable care in
the performance of its duties under such Agreement.

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders of Nakornthai Strip Mill Public Company Limited:
 
    We have audited the accompanying balance sheets of Nakornthai Strip Mill
Public Company Limited as of December 31, 1995, 1996 and 1997 and the related
statements of income, changes in shareholders' equity and cash flows for the
years then ended all expressed in Thai Baht. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards in Thailand, which are substantially similar with those in the United
States of America. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
    We draw attention to Note 2 to the financial statements. The operations of
the Company have been affected and will continue to be affected for the
foreseeable future by the economic conditions in Thailand and Asia Pacific
Region in general.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Nakornthai Strip Mill Public
Company Limited as of December 31, 1995, 1996 and 1997 and the results of its
operations and cash flows for the years then ended, in conformity with generally
accepted accounting principles in Thailand.
 
    Generally accepted accounting principles in Thailand vary in certain
significant respects from generally accepted accounting principles in the United
States of America. Application of generally accepted accounting principles in
the United States would have affected shareholders' equity as of December 31,
1995, 1996 and 1997 and results of operations for the years then ended to the
extent summarized in Note 22 to the financial statements.

                         NOTES TO FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1995, 1996 AND 1997
 
NOTE 1--NATURE OF OPERATIONS
 
    Nakornthai Strip Mill Public Company Limited (the "Company") is a Thai
public company listed on the Stock Exchange of Thailand. The Company was founded
in 1994 to become a producer of flat rolled steel for both domestic use and
export. Through December 31, 1997, the Company was in the development stage and
its activities primarily related to the construction of its mini-mill, which is
located in Thailand. The Company's hot mill, the core of the mini-mill, has been
completed as of December 31, 1997. The Company expects to begin commercial
production of hot-rolled steel in early 1998. The Company's facilities for
production of direct reduced iron and for production of cold-rolled, galvanized
and other value added steel products are still under construction. The Company
expects to complete these facilities in the first quarter of 1999.
 
NOTE 2--ECONOMIC ENVIRONMENT
 
    The Company expects to sell a significant portion of its products in
Thailand and other countries in the Asia/Pacific region. In addition,
substantially all of the Company's assets are located in Thailand. Recent
adverse economic conditions in Thailand and other countries in the Asia/Pacific
region have resulted in, among other things, a national liquidity crisis in
Thailand, significant depreciation in the value of the Thai Baht and certain
other currencies in the Asia/Pacific region relative to, among others, the U.S.
Dollar, sharply higher domestic interest rates, reduced opportunities for
refinancing or refunding of maturing debts, and a general reduction in spending
throughout the region. In order to partially address this situation, the
Government of Thailand and certain other governments of countries within the
Asia/ Pacific region sought assistance from the International Monetary Fund and
announced policy packages intended to address the structural weaknesses within
their respective economies and financial sectors. These reform policies are
intended to alleviate the economic crisis in Thailand and other countries in the
Asia/Pacific region and improve their respective economies over time. However,
these reform policies may not be effective in the near term or at all. The
current economic conditions in Thailand, and similar conditions in the
Asia/Pacific region, could have a significant negative effect on the financial
position, cash flow, operating results and general levels of business activities
of the Company.
 
    As of December 31, 1997, the Company had net foreign currency denominated
liabilities of approximately Baht 16.3 billion, substantially all in U.S.
Dollars. As a result of the previously discussed depreciation in the Thai Baht
relative to the U.S. Dollar, the Company incurred significant unrealized foreign
exchange losses during 1997. The Company's ultimate foreign exchange gains or
losses with respect to currency fluctuations will depend on future currency
exchange rates and other factors.
 
    As a result of the conditions noted in the previous paragraph, it is at
least reasonably possible that the estimates utilized by the Company as a basis
for supporting the carrying amounts of certain long-lived assets will change in
the near term.

NOTE 6--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    ALLOWANCE FOR DOUBTFUL ACCOUNTS
 
    Allowance for doubtful accounts is an estimate of those amounts which may
prove to be uncollectible, based on review of the current status of existing
receivables.
 
    INVENTORIES
 
    Inventories consist of raw materials and supplies that are stated at the
lower of cost, using the first in, first out method, or market, except fuel and
natural gas which are costed using a moving average method.
 
    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are stated at cost. Depreciation is computed
by the straight-line method based on the estimated useful lives of assets of
5-20 years. Depreciation of property and equipment used for administrative
purposes for the years ended December 31, 1995, 1996 and 1997 in the amount of
Baht 1,277,019, 6,053,340 and 12,841,716, respectively, is included in deferred
charges. Interest expense and exchange gains or losses related to liabilities
incurred to finance construction is capitalized as part of the cost of
construction.
 
    DEFERRED CHARGES
 
    Deferred charges consist of pre-operating expenses, which are net of
interest income in the amount of Baht 111.9 million, 202.8 million and 145.0
million for the years ended December 31, 1995, 1996 and 1997, respectively,

NOTE 6--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
receivable from finance companies are similar to interest bearing deposits, and
generally have maturities of 3 months or less, the Company has adopted a policy
of treating all promissory notes receivable as investments.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
    INCOME TAXES
 
    Income taxes are recognized on the basis of the estimated current income tax
liability for the period in accordance with existing regulations giving
consideration to applicable exemptions.
 
    LOSS PER SHARE
 
    Loss per share is computed by dividing net loss by the weighted average
number of shares outstanding during each year. Weighted average shares
outstanding during the year ended December 31, 1995, 1996 and 1997 were
292,083,333, 535,000,000 and 560,000,000, respectively.

NOTE 12--LONG-TERM AGREEMENT
 
    In August 1996, the Company entered into an agreement (the "Agreement") with
a steel producer based in the United States of America (the "US Company")
whereby the US Company would provide training and data relating to the business
processes that the Company would use in its operations. As compensation for
these services, the US Company was to have received cash of up to U.S.$15
million, options to purchase a minimum of 2 1/2% and a maximum of 5% of the
Company's shares outstanding at the date of exercise and reimbursement of
out-of-pocket expenses. The minimum cash compensation was to have been U.S.$5
million. The first installment of U.S.$2.5 million was paid in August 1996 and a
second installment of U.S.$2.5 million was due in August 1997. The remaining
cash of up to U.S.$10 million was to have been payable in increments as
incentive compensation based on the successful start-up of the manufacturing
facility and achievement of certain operating performance objectives over the
first 24 months of operation. Under the Agreement, the options were granted
concurrently with the execution of the Agreement, but the percentage of the
Company's outstanding shares that could be issued upon exercise of the options
in excess of the 2 1/2% minimum was dependent upon the Company achieving certain
production results determined under a preset production model. The purchase
price of shares upon exercise of the options was equal to the lesser of 75% of
the market price at the date of exercise or Baht 16 per share. The options were
exercisable beginning in August 1998 and expired five years thereafter.
 
    The Company did not make the cash payment of U.S.$2.5 million due in August
1997. However, by agreement between the Company and the US Company, the due date
was subsequently extended to October 1, 1997. The Company was unable to make
such payment and the US Company delivered a termination notice on October 27,
1997. The Agreement provides that, upon proper termination, any unpaid amount of
the maximum sum of U.S.$15 million that the US Company could have earned shall
be considered immediately earned and due and payable. The Company believes that
the notice of termination was improper under the terms of the Agreement, and
that the US Company repudiated the Agreement prior to the extended due date for
the payment. The minimum cash compensation of U.S.$5 million, consisting of
U.S.$2.5 million paid in cash and U.S.$2.5 million accrued, and out-of-pocket
expenses paid to the US Company are included in deferred charges as
pre-operating expenses. See subsequent event in Note 21.
 
NOTE 13--SHORT-TERM LOANS
 
    Short-term loans represent loans from individuals. The Company issued
unsecured promissory notes due on demand bearing interest at 18% per annum.

                        DECEMBER 31, 1995, 1996 AND 1997
 
NOTE 14--LONG-TERM DEBT
 
    On September 27, 1995, the Company entered into a long-term debt agreement
with a group of Thai financial institutions. The agreement makes amounts
available in both U.S. Dollars and in Baht. The Company may borrow up to U.S.$
308 million and up to Baht 3,300 million. U.S.$ amounts borrowed under this
agreement bear interest payable quarterly at SIBOR plus 2.5% per annum and Baht
amounts bear interest at MLR plus 0.5% per annum. These loans are due in 13
semi-annual installments beginning on the earlier of four years after the first
amount is borrowed or two years after the Company's manufacturing facility
begins operations. The Company first borrowed amounts under this agreement in
1996. The amount outstanding at December 31, 1996 is a US Dollar loan of US.$
162 million. The amount outstanding at December 31, 1997 is a U.S.$ loan of
280.51 million and a Baht loan of Baht 3,300 million.
 
    After the manufacturing facility begins operations, the Company must reserve
0.5% of the balance of the U.S.$ loans outstanding as of each year end until the
total reserve is more than 5% of the outstanding balance of the U.S.$ loans.
Such amount must be deposited in a separate bank account and pledged to the
lenders. Substantially all of the Company's property, plant and equipment is
pledged as collateral for this long-term debt.
 
    The agreement contains certain restrictive covenants including the
following. The Company may not utilize amounts borrowed under the agreement for
any business other than the hot-rolled strip mill project. The Company may not
pay dividends in excess of 70% of net income during each year. The Company may
not dispose of, mortgage, pledge or otherwise encumber its property and
equipment or any other assets which is not in the ordinary course of its
business. The Company may not provide guarantees to or on behalf of other
persons which is not in the ordinary course of its business. The Company may not
reduce capital, or dispose of or transfer assets to its shareholders. The
agreement also discusses certain events which would be considered events of
default including any situation that occurred which, in the opinion of the
lenders, is a material adverse change in the business operation, property or
indebtedness of the Company that would impair the Company's ability to comply
with this agreement. A default of payment due to any creditor would also be an
event of default. The Company's obligations under the agreement are guaranteed
by a shareholder. Lawsuits against the guarantor, or if the guarantor is
deceased or otherwise incapacitated, would also be an event of default. If the
Company violates any of these restrictive covenants or an event of default
occurs, all amounts owed under the agreement become immediately due upon the
receipt of notice from the lenders.
 
    The Company was not in compliance with certain restrictive covenants and
certain events of default existed as of December 31, 1997. See subsequent event
in Note 21.

NOTE 21--SUBSEQUENT EVENTS
 
    On April 3, 1998, the Company paid U.S.$2.5 million to the US Company
discussed in Note 12 under a letter providing that such payment was in full
satisfaction of all of the Company's obligations under the Company's agreement
with the US Company. By letter dated May 12, 1998, the US Company asserted a
claim to the remaining U.S.$10 million of cash compensation and options to
purchase 5% of the Company's outstanding shares. However, the Company still does
not believe it has any future obligation to the US Company for such cash
compensation and or stock options for the reasons discussed in Note 12 and
intends to vigorously defend against this claim.
 
    The shareholders also approved a special resolution authorizing the Company
to issue and offer warrants for sale as described below.
 
    On March 31, 1998, the Company registered the increase of its share capital
from Baht 5,600,000,000 to Baht 7,186,398,640 dividing into 718,639,864 fully
paid shares with Baht 10 par value.
 
    On March 12, 1998, NSM Steel and NSM Delaware (collectively, the "Issuers")
completed on offering of long-term notes and debentures for total proceeds of
approximately U.S.$444 million. The Issuers immediately loaned the proceeds of
the debt offerings to the Company on terms substantially the same as the terms
received by the Issuers. The long-term notes were issued with an aggregate
principal amount due at maturity of US$ 249,000,000 and US$ 203,500,000 and
mature on February 1, 2006 and February 1, 2008, respectively. The long-term
notes bear interest at the rate of 12% to 12 1/4% per annum that will be paid
semi-annually. The long-term notes were issued at a discount to generate gross
proceeds of US$ 400,604,000. The purchasers of a portion of the long-term notes
received warrants (the "Warrants") to purchase 128,834,356 ordinary shares of
the Company at an exercise price of Baht 10 per share. The Warrants are
exercisable beginning on the first anniversary date of the issue date and expire
on February 1, 2008. The debentures were issued with an aggregate principal
amount due at maturity of US$ 53,133,016 and are due February 1, 2009. The
debentures bear interest at 12 3/4% per annum that will be paid semi-annually.
The debentures were issued at a discount to generate gross proceeds of US$
43,500,000. In conjunction with the debentures offering, the Company issued
64,417,180 ordinary shares for gross proceeds of Baht 644,171,800 through a
private placement. The long-term notes and loans from Thai financial
institutions are secured by a first mortgage over the land and buildings
comprising the mill and all

machinery and equipment located at the mill. The debentures are secured by a
second mortgage on the land and buildings comprising the mill and all machinery
and equipment located at the mill. In addition, the long-term notes and
debentures are secured by all funds remaining in certain cash accounts
maintained with a trustee in the United States. A substantial portion of the
gross proceeds of the Company's recent debt and equity offerings are reserved
for capital expenditures and payment of interest on the long-term notes and
debentures. The Company's access to these funds is restricted to these uses. The
maximum amount of the gross proceeds which can be used for working capital and
general corporate purposes is US$ 70 million.
 
    In connection with the offering, the Company entered into several other
agreements. The Company entered into a 10 year contract with a Management
Company. Pursuant to the agreement, the Company will assign and delegate to
Management Co. the exclusive right and obligation to control, posses and manage
all business affairs for Company. Under the agreement, Management Co. shall not
be entitled to any fee or other compensation for its services. The Company also
entered into a 10 year contract with Steel Dynamics, Inc., "(SDI)", under which
SDI will provide Management Co. with consultation and technical and advisory
services. As compensation for these services, SDI will receive an annual fee of
US$ 2 million and a one-time incentive fee of US$ 1.3 million. The Company also
entered into a license and technology sharing agreement with SDI for a period of
10 years. As compensation for the rights granted to the Company by SDI, the
Company issued 74,468,090 of its ordinary shares to SDI and granted warrants to
SDI to purchase up to 11,421,480 ordinary shares of the Company for Baht 10 per
share. Concurrent with exercise of the warrants, the Company would pay Baht 10
per share to SDI such that there would be no net cost to SDI. The warrants are
exerciseable only to the extent the Warrants discussed above are exercised such
that SDI would maintain its percentage ownership of the Company. Any unexercised
warrants expire on March 12, 2008. The Company also entered into eight year
sales agreements ("Offtake Agreements") with two international steel trading
companies. Pursuant to the Offtake Agreements, the trading companies are
obligated to purchase 100% of the Company's production in 1998, 1999 and 2000,
and 25% of the Company's production in the years 2001 through 2005. The Company
may, at its option, reduce the percentage of its production sold under the
agreements to as little as 67% in 1998, 50% in 1999 and 25% in 2000.
 
    Also in connection with the offering, the Company amended its long-term debt
agreement with the Thai financial institutions. Also, the Company pre-paid US$
50 million of principal and paid all accrued interest due under the loan from
the Thai financial institutions by using funds from the offering. The amendment
modified the restrictive covenants and waived all past violations of the
agreement upon successful completion of the offering. As amended, the remaining
principle is payable semi-annually beginning in the first quarter of 2000.
Installments will be in the amount of US$ 24.01 million for the U.S.$ loan and
Baht 169.18 million for the Baht loan. The first installment will be payable on
March 1, 2000. Interest is payable quarterly at the rate of SIBOR + 2.5% per
annum for the US$ loan and MLR+0.5% per annum for the Baht loan. Also as
amended, the Company must prepay the outstanding balance of the loans by an
amount equal to 50% of annual earnings before depreciation and amortization,
less scheduled debt repayments and maintenance capital expenditures, beginning
in the year 2000.

NOTE 22--RECONCILIATION TO ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE
UNITED STATES OF AMERICA
 
    The Company's financial statements have been prepared in accordance with
Thai GAAP, which differs in certain material respects from Generally Accepted
Accounting Principles in the United States of America ("U.S. GAAP"). Differences
that have an effect on net loss and shareholders' equity are as follows:
 
    A. FOREIGN EXCHANGE GAINS AND LOSSES
 
    Under Thai GAAP, foreign exchange translation gains and losses related to
foreign currency liabilities incurred specifically to fund construction of plant
and equipment are capitalized during the construction period. Under U.S. GAAP,
all foreign exchange translation gains and losses must be included in earnings
in the period in which such gains and losses arise.
 
    B. DEFERRED CHARGES
 
    Thai GAAP permits the deferral of pre-operating expenses, net of interest
income earned, during the pre-operating period. For U.S. GAAP purposes, these
expenses have been expensed as incurred and the related revenue recognized in
the period earned. Under U.S. GAAP, the minimum cash compensation due under the
agreement discussed in Note 12 was being amortized as administrative expense
over the approximate 17 month period of service. The accrual ceased upon
termination of the agreement.
 
    Thai GAAP permits the capitalization and amortization of expenses incurred
for the acquisition of debt as an asset which is then amortized over the life of
the debt. Such amortization is generally provided using the straight-line
method. U.S. GAAP requires the capitalization of debt acquisition costs which
are subsequently amortized over the life of the related debt using the interest
method. The U.S. GAAP income statement has not been adjusted because the impact
of such difference is immaterial.
 
    Both Thai GAAP and U.S. GAAP require the capitalization of costs incurred to
get an asset ready for its intended use. Under Thai GAAP, the cost of
engineering studies for construction projects is capitalized as deferred charges
and amortized on a straight-line basis over a period unrelated to the useful
life of the related assets. Under U.S. GAAP, all costs of getting an asset ready
for its intended use are capitalized as part of the historical cost of that
asset and depreciated over its useful life. This difference currently affects
only classification of the costs but will effect depreciation and shareholders'
equity in future periods.
 
    Under Thai GAAP, costs incurred in connection with offerings of share
capital are deferred and amortized to income. Under U.S. GAAP, such costs are
charged against the proceeds from the offering.
 
    C. STOCK OPTIONS
 
    Under Thai GAAP, no value was ascribed to the stock options discussed in
Note 12 due to the variable exercise price and number of shares. Under U.S.
GAAP, the fair value of the options is not estimable and, therefore, the current
intrinsic value of outstanding options was being expensed through September 30,
1997 as an administrative cost over the vesting period. As discussed Notes 12
and 21, management believes the options have been canceled.

NOTE 22--RECONCILIATION TO ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE
UNITED STATES OF AMERICA (CONTINUED)
    D. DEFERRED INCOME TAXES
 
    Thai GAAP has no requirement for establishing deferred income tax assets or
liabilities. The Company has adopted a policy whereby income taxes are
recognized on the basis of the estimated current income tax liability for the
period in accordance with existing regulations giving consideration to
applicable exemptions.
 
    U.S. GAAP requires deferred tax assets and liabilities to be established for
temporary differences between the tax and financial reporting bases of assets
and liabilities. Deferred tax assets and liabilities are measured using the
enacted tax rates applicable to the periods in which the differences are
expected to affect taxable income. Deferred income tax assets are also
established for tax losses which may be carried forward and used to reduce
future taxable income. U.S. GAAP requires a valuation allowance to be
established sufficient to reduce any deferred tax assets to the amount that,
based on the weight of the available evidence, is more likely than not to be
recovered.
 
    E. CAPITALIZATION OF INTEREST EXPENSE
 
    Under Thai GAAP, all interest incurred during the construction period on
debt specifically related to funding construction of plant and equipment is
capitalized as part of the cost of acquiring the assets. Under U.S. GAAP,
interest costs incurred during the construction period are required to be
capitalized as part of the cost of acquiring the asset. Interest costs
recognized on all borrowings and other obligations are eligible for
capitalization. The amount capitalized under U.S. GAAP is based on the effective
interest rates of outstanding borrowings applied to the cumulative expenditures
for the asset. If specific new borrowings are associated with the asset, the
effective interest rate on that borrowing may be applied to that portion of the
cumulative expenditures for the asset. All interest costs have been capitalized
under both Thai GAAP and U.S. GAAP; therefore, the U.S. GAAP income statement
has not been adjusted for this difference. However, a portion of interest
expense amounting to Baht 3.1 million and Baht 56.8 million at December 31, 1996
and 1997, respectively was capitalized as pre-operating expense for Thai GAAP
and such amount has been reclassified to construction in progress under U.S.
GAAP.
 
    F. INSURANCE CLAIM
 
    Under Thai GAAP, as discussed in Note 8, the Company is carrying the costs
of recovering a damaged boat carrying its equipment as a receivable from its
insurance company. Under Thai GAAP, such amount will be reclassified as a
component of the equipment cost if the claim is not successful. Under U.S. GAAP,
such costs are not considered part of the equipment cost and, due to
uncertainties about recoverability from the insurance company, have been
expensed as incurred.
 
    G. RECENT CHANGES IN US GAAP
 
    In June 1997, the U.S. Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130 which requires the
reporting and display of comprehensive income and its components (revenues,
expenses, gains and losses). SFAS No. 130 also requires that the components of
comprehensive income be reported in a financial statement that is displayed with
equal prominence as other financial statements. SFAS No. 130 is effective for
the Company's 1998 financial

UNITED STATES OF AMERICA (CONTINUED)
statements and requires reclassification of all financial statements for prior
periods presented under US GAAP. The Company has not assessed the impact of SFAS
No. 130.
 
    In June 1997, the FASB issued SFAS No. 131 which requires disclosure of
certain information for the Company's reportable operating segments. SFAS No.
131 defines a reportable operating segment as a component of the Company about
which separate financial information is available that is evaluated regularly by
management in deciding how to allocate resources and in assessing performance.

    D. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The fair value of a financial instrument is the amount at which the
instrument could be exchanged in a current transaction between willing parties.
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it was practical to estimate that
value:
 
    - The carrying amount of cash on hand and at banks, short-term investments,
      value added tax recoverable, bank overdrafts and loan from financial
      institutions, accounts payable, retention payables and short-term loans
      approximate fair value because of the short maturity of these instruments.
 
    - The carrying amount of other receivables from related parties and notes
      payable and advances from related party are materially the same as their
      fair value.
 
    - The fair value of long-term debt is estimated by discounting the future
      cash flows at rates currently offered for similar debt instruments of
      comparable maturities. The estimated fair value of long-term debt at
      December 31, 1996 and 1997 is Baht 4,056 million and Baht 16,442 million,
      respectively.

                            THE KINGDOM OF THAILAND
 
    The following information regarding the Kingdom of Thailand ("Thailand") is
included for information only and has not been independently verified by the
Company or any of their respective affiliates or advisors. All of the data and
other information included below has been obtained from published or public
official sources of Thailand.
 
GENERAL
 
    Thailand, formerly known as Siam, is situated in Southeast Asia. It is
bounded on the north and west by the Union of Myanmar (Burma), on the north and
east by Laos and on the southeast by Cambodia. In the south it becomes a
peninsula bounded by the Indian Ocean in the west, Malaysia in the south and the
South China Sea in the east. The country covers an area of 514,000 square
kilometers and has an estimated population of 60 million.
 
    Approximately 70% of the population lives in the central and northeastern
regions of the country. By far the largest urban center is Bangkok (which
includes Thon Buri), the capital, where the population has been growing more
rapidly than the national population as a whole, increasing from 3.7 million in
1971 to approximately 5.6 million at the end of 1995.
 
    Approximately 85% of the population of Thailand is of Thai ethnic origin.
The most important minority group is the ethnic Chinese who comprise over 12% of
the population. The predominant religion in Thailand is Buddhism to which 95% of
the population adheres. Islam accounts for 4% and is concentrated in the south
adjacent to Malaysia. The balance of the population is predominantly Christian.
The literacy rate is over 90% for adults over 15 years of age. The official
language is Thai, but the use of English is encouraged, and is part of the
school curriculum.
 
GOVERNMENT STRUCTURE AND POLITICS
 
    Thailand is a constitutional monarchy. His Majesty King Bhumibol Adulyadej,
Rama IX, who ascended the throne in 1946, is a highly respected symbol of
national unity and provides an important stabilizing influence in the country.
 
    Under the constitution, the King is the Head of State, Commander of the
Armed Forces and Patron of all Religions. He has power to, upon the advice of
the Prime Minister, declare and lift martial law, declare war with the approval
of the National Assembly, conclude treaties with other countries or
international organizations, grant pardons, appoint and remove high ranking
officials in the civil service and commissioned officers in the armed forces. He
is advised in the exercise of his functions by the Privy Council, appointed by
royal command.
 
    The executive power is vested in the cabinet ("Council of Ministers"), which
consists of the Prime Minister and not more than 35 other ministers, each
appointed by royal consent. The cabinet can be dismissed by a vote of
no-confidence of the House of Representatives. The new constitution, enacted in
October 1997 stipulates that the members of the House of Representatives will
lose memberships if they become ministers.
 
    Legislative power is exercised by the bicameral National Assembly, which is
comprised of the Senate and the House of Representatives. Under the
constitution, the President of the House of Representatives is also the
President of the National Assembly. The Prime Minister is nominated by the
president of the National Assembly and appointed by the King. The 200 members of
the Senate, who may not belong to a political party, are elected for six-year
terms. There are 500 members of the House of Representatives, 400 of whom are
elected by popular vote together with 100 members elected under a party list
system. The term of office of members of the House of Representatives is four
years.
 
                                      A-1

    The Thai legal system with respect to the criminal, civil, commercial, and
special codes is based on British and European legal systems. There is also an
extensive system of administrative law consisting of royal decrees, executive
orders, and ministerial regulations. Thai law relating to family and inheritance
matters is codified based upon traditional Thai laws. The judicial power is
exercised by the courts of justice, consisting of the courts of first instance,
the court of appeal and the Supreme Court. The King appoints all judges of the
courts of justice after they have been approved by the Judicial Commission.
 
    For the purposes of administration the country is divided into 76 provinces,
each under the control of a governor; each province is divided into districts,
sub-districts and villages. The governors are appointed by the King on the
advice of the Minister of Interior, except for the governor of Bangkok, who is
directly elected by Bangkok residents.
 
RECENT POLITICAL DEVELOPMENTS
 
    After civil unrest in May 1992, an interim government was set up under Mr.
Anand Panyarachun and the House of Representatives was dissolved for a general
election that was held on September 13, 1992. The Democrat party won the most
seats in that election and Mr. Chuan Leekpai, the Democrat Party leader, became
Prime Minister and organized a five party coalition cabinet. However, due to
controversy in connection with the Land Reform Program, Prime Minister Chuan was
forced to dissolve the House. In the ensuing nationwide election held on July 2,
1995, the Chart Thai party won the largest number of seats in the House of
Representatives, leading to the appointment of Mr. Banharn Silpa-archa as Prime
Minister. In September 1996, however, Mr. Banharn was the subject of a censure
debate in the House of Representatives, during which various charges were made
against him, including mismanagement of the Thai economy and improper conduct by
members of his administration. On September 21, prior to the censure vote, Mr.
Banharn announced that he would resign as Prime Minister within the following
week. On September 27, the Prime Minister dissolved the House of
Representatives, as permitted by the constitution in effect at that time, and
announced a new general election, which was held on November 17, 1996. In the
election, the New Aspiration Party ("NAP") headed by former army chief General
Chavalit Yongchaiyudh, won the largest number of seats in Parliament, capturing
125 of 393 seats. NAP's total of 125 seats, however, was far short of an
absolute majority, so that a coalition government of six parties, which together
had a 24-seat majority, was created to control the House of Representatives. The
principal opposition to the new government was the Democrat Party, which won 123
seats in the election.
 
    This coalition government included many members of the previous coalition
government and in its first nine months carried on many of the policies adopted
by the previous government, including economic policies. On September 27, 1997,
Prime Minister Chavalit survived a no confidence vote in the National Assembly
amid widespread criticism of the Government's response to Thailand's economic
crisis and controversy over political reform and a draft new constitution, which
the Prime Minister initially opposed and ultimately supported. However, on
November 7, 1997, Prime Minister Chavalit resigned from office under intense
political pressure. In the interim before constitutionally mandated elections,
Mr. Chuan Leekpai has been appointed to the office of Prime Minister. He
presides over a coalition government that includes the major parties that formed
the opposition to the former government of Prime Minister Chavalit.
 
    On September 27, 1997, the National Assembly approved a new constitution,
which was signed by His Majesty the King on October 11, 1997 and took effect the
same day upon official publication. The new constitution is seen by its
supporters as a means of reforming and modernizing the Thai political system.
 
    The new constitution, which is the first to have sought grassroots input,
expands citizens' rights, increases civil liberties, grants greater access to
official information and encourages participation in the governmental
decision-making process. The rights of local communities to participate in
managing natural resources and the environment have been spelled out. It is
unconstitutional to discriminate against Thai people on the basis of gender,
origin of birth, country of birth, race, language or religious faith. The new
 
                                      A-2

constitution also creates monitoring mechanisms against corruption. Members of
the Council of Ministers, as well as their spouses and children, are required to
disclose their assets, and members of the House of Representatives found to be
involved in misconduct can be more easily dismissed. The new constitution makes
voting compulsory. Formerly, low voter turn-out was considered by some to
encourage vote buying.
 
    The constitution allows the Senate more power to scrutinize bills passed by
the House of Representatives and also to appoint members of monitoring agencies,
including a National Counter-Corruption Commission and certain Constitutional
Court judges. In addition, the Senate is empowered to appoint members of the
Election Commission, which supervises and manages all elections to ensure
fairness. Under the constitution, the National Assembly must, by mid-June 1998,
complete the consideration and approval of laws in respect of the elections of
members to the House of Representatives and Senate, the Election Commission and
political parties.
 
FOREIGN RELATIONS
 
    Thailand has historically adopted a flexible approach in its conduct of
external relations. The success of this approach is evidenced by the fact that
Thailand is the only country in Southeast Asia, and one of the few in all of
Asia, never to be colonized by Western powers. Following the end of World War
II, Thailand's main external concern was to ensure that the spread of communism,
first in China and later in Vietnam, Cambodia and Laos, did not spill over into
Thailand. Consequently, in the early 1950's the Thai Government decided to align
with the West in general, and the United States in particular. In 1954, Thailand
became a party to a regional collective security arrangement called the
Southeast Asia Treaty Organization ("SEATO"). Although SEATO was dissolved in
1977, Thailand and the United States have remained allies under the Manila Pact,
which served as a basis for SEATO and remains in force today.
 
    Thailand is a member of, and enjoys good relations with other members of,
the Association of Southeast Asia Nations, namely, Brunei, Indonesia, Malaysia,
the Philippines, Singapore, Vietnam, Laos and the Union of Myanmar (Burma).
 
    Thailand has shown a strong interest in the development of multilateral
regional relations. It has been a signatory to a number of international
treaties including: the World Trade Organization (formerly the General Agreement
on Tariffs and Trade) (WTO); Agreement between the Government of the Kingdom of
Thailand, the Government of Malaysia and the Government of the Republic of
Indonesia relating to the Delimitation of Continental Shelf Boundaries in the
Northern Part of the Straits of Malacca; the Fifth International Tin Agreement;
the Treaty of Amity and Economic Relations Between the Kingdom of Thailand and
the United States of America; and the International Natural Rubber Agreement. In
the international financial context, Thailand is affiliated with major
multilateral lending institutions, including: the IMF, the World Bank, the
International Development Association (IDA), the International Finance
Corporation (IFC), and the (Asian Development Bank (ADB). Thailand is also a
member of the United Nations, as well as a number of specialized United Nations
agencies, and of the International Coffee Organization, the International Sugar
Organization, the International Natural Rubber Organization and the
International Jute and Allied Fibres Organization.
 
    Thailand is a party to the ASEAN Free Trade Agreement (AFTA) under which no
tariffs greater than 5% will be applied after 2003 on products, other than
certain unprocessed agricultural products, traded among the ASEAN member
countries. AFTA also requires that tariffs on such unprocessed agricultural
products be reduced by 2005.
 
    In November 1996, Thailand and the United States of America signed the
"Convention Between the Government of the United States of America and the
Government of the Kingdom of Thailand for the Avoidance of Double Taxation and
the Prevention of Fiscal Evasion with Respect to Taxes on Income." The treaty
has been ratified by both respective countries and came into force on January 1,
1998, although provisions concerning withholding tax will come into effect only
after a six-month delay. The treaty is expected to improve investment conditions
for U.S. investors.
 
                                      A-3

ECONOMY
 
    Thailand's economy operates as a mixed economic system in which the private
sector plays a dominant role. The policy of the government has been to operate
most public utilities as well as to control a number of monopolies, such as the
lottery and domestic tobacco industry, and some other industries, but not to
displace private enterprise in the commercial or industrial sectors of the
economy, except where private capital is unable to develop essential industrial
projects. In particular, the government has begun to look to private industry in
connection with the modernization of telephone services and the development of a
mass transit system and has begun to privatize air transport.
 
    While traditionally the Thai economy was based on agriculture, since the
early 1960's, the country has diversified its agricultural base and placed
increasing emphasis on the industrial and service sectors. The contribution of
agriculture, including crops, livestock, fishery, forestry, agricultural
services, and simple agricultural processing products to Gross Domestic Product
("GDP") decreased from 24% in 1979 to an estimated 10.7% in 1996 and increased
slightly to an estimated 11.2% in 1997, while during the same period the
industrial sector, including mining and quarrying, manufacturing, construction,
transportation and communication as well as electricity and water supply rose
from 36.1% to 47.2%. The contribution of the service sector, including wholesale
and retail trade, banking, insurance and real estate, ownership of dwellings,
public administration and defense and services increased from 39.9% to 41.6%
during the same period. Manufacturing activities at present range from the
production of major construction materials, electrical and electronic components
and goods to the processing of agricultural products.
 
    The performance of Thailand's economy from 1992 through 1996 generally met
the targets set in the Seventh National and Social Development Plan (covering
fiscal years 1992-1996) (the "Seventh Plan"). Nominal GDP increased by an
estimated 70.52% during the period, from approximately 2,830.9 billion Baht in
1992 to approximately 4,827.2 billion Baht in 1996 and per capita GDP rose from
49,410 Baht in 1992 to an estimated 79,653 Baht in 1997. Average annual growth
in real GDP was 8.0% compared to 8.2% targeted in the Seventh Plan; average
annual growth in private sector investment was 7.0%, compared to 8.8% targeted
in the Seventh Plan and exports and imports grew by an average of 14.2% and
13.6%, respectively, compared to 14.7% and 11.4%, respectively, targeted in the
Seventh Plan. Inflation during the period rose at an average annual rate of
4.8%, compared to 5.6% targeted in the Seventh Plan. Real GDP in Thailand grew
by an estimated 5.5% in 1995, a decline from the previous four years.
 
    Thailand's economy currently is experiencing significant contraction. Real
GDP growth is expected to decline from negative 0.4% in 1997 to a range of
negative 4.0% to negative 5.5% in 1998. Under the macroeconomic assumptions
developed in conjunction with the IMF Financial Assistance Program, domestic
consumption is expected to decline by 8.0% and gross fixed investment is
expected to decline by 24.0% in 1998.
 
    The preparation of the Eighth Plan represented a departure from past
practice, as the Eighth Plan is intended to provide only general guidelines for
economic development. The preparation of the Eighth Plan involved extensive
public consultation through seminars held throughout Thailand. Under the Eighth
Plan, the Government's broad policy is to achieve balanced economic growth with
stability. As originally drafted, the Eighth Plan called for, among other
things, reducing the current account deficit as a percentage of GDP, controlling
inflation, mobilizing household savings to at least 10% of GDP, reducing the
percentage of the population below the defined poverty level to less than 10%,
improving the development of human resources and the quality of life, utilizing,
preserving and rehabilitating the natural environment and increasing the
quantity and quality of basic infrastructure in rural areas. One of the main
focuses of the Eighth Plan is human resource development and enhancement of the
productivity of the Thai labor force. The Government had previously increased
the level of compulsory education in the country from six years to nine years
during the Seventh Plan and has made efforts toward increasing the number of
technicians and skilled workers. Meanwhile, the Government is also actively
encouraging private sector corporations to re-train their workforce.
 
                                      A-4

    The devaluation of the Baht during 1997, combined with the concurrent crisis
in Thailand's financial sector and property markets and related adverse economic
developments in Thailand and other Asian countries, have substantially altered
the assumptions under which the Eighth Plan was developed. Accordingly, the
Government has adopted amendments to the Eighth Plan that reflect Thailand's
current economic and social environment and the economic rehabilitation program
developed in connection with the IMF Financial Assistance Program. The
amendments reflect lower public and private investment spending targets,
increased monitoring of private sector external debt, emphasis of fiscal and
monetary policy on controlling inflation, financial reform, increased export
competitiveness and alleviation of social problems arising from the economic
slowdown, including, INTER ALIA, unemployment. The amendments also target
acceleration of state enterprise reform, decentralization of government power,
privatization of state enterprises, development of human resource programs and
participation of non-governmental organizations in decision-making and policy
formation.
 
    Thailand has obtained a U.S.$17.2 billion loan package from the IMF. The IMF
has imposed strict austerity measures as conditions to this package. These
include tax increases, government spending cuts and implementation of a plan for
financial reform and rehabilitation. In addition, Thailand has agreed to the
following adjusted fiscal goals:
 
        1. Maintain economic growth rates at 3-4 percent in 1997-1998 and aim
    for a potential growth rate of 6-7 percent over the medium term.
 
        2. Reduce inflation to 4-5 percent following an initial increase to an
    average of 7-8 percent in 1997-1998.
 
        3. Reduce the current account deficit to 5 percent of GDP in 1997 and to
    a sustainable level of 3 percent over the medium term.
 
        4. Maintain gross international reserves of about U.S.$23 billion in
    1997 and U.S.$25 billion in 1998, equivalent to approximately 4 months of
    imports.
 
    As a result of the continued slowdown in the Thai economy, which has been
more severe than previously anticipated due in part to the economic difficulties
experienced by other Asian countries (including lower demand from Japan and
other Southeast Asian trading partners), more pronounced weakness in private
consumption and investment demand and continued liquidity shortages, the
Government, in consultation with the IMF, revised in November 1997, February
1998 and May 1998 certain of its macroeconomic assumptions. The most recent
revisions in May 1998 included lowering the real GDP growth rate for 1998 to a
range of negative 4.0% to negative 5.5% (from negative 3.0% to negative 3.5%
following the February 1998 review), revising the expected inflation level to an
average of 10.5% in 1998 (from 11.6% following the February 1998 review),
increasing the consolidated public sector deficit to approximately 3.0% of GDP
(from 2.0% GDP following the February 1998 review) for the 1998 fiscal year,
increasing the current account surplus to 6.9% of GDP (from 4.0% of GDP
following the February 1998 review) in 1998 and maintaining gross international
reserves of U.S.$26-28 billion for 1998 (as compared to reserves of U.S.$23-25
billion following the February 1998 review) (approximately 6.2 to 6.7 months of
estimated 1998 import value). Actual performance of the economy could vary from
these assumptions, and future adverse developments in Asia could further
exacerbate Thailand's economic difficulties, including by adversely affecting
Thai exports.
 
    The board of the IMF most recently met on December 8, 1997 to evaluate
Thailand's progress in meeting package conditions and approve a second round of
drawings in the amount of U.S.$810 million. On March 9, 1998, the IMF approved a
third round of drawings in the amount of U.S.$270 million. The government
expects to receive an additional disbursement from the IMF of U.S.$138 million
in mid-June 1998. Since August 1997, the IMF has made funds available to
Thailand in the amount of U.S.$2.67 billion.
 
                                      A-5

    In addition, the World Bank is providing a U.S.$1.5 billion loan package in
order to assist in the reform of the Thai Financial system. The World Bank
released U.S.$350 million on December 30, 1997. Also, Asian Development Bank is
providing U.S.$1.2 billion loan package for on-going project loans and
structural adjustment loans. On December 20, 1997 and March 18, 1998, the total
of U.S.$600 million was released to Thailand.
 
PRIVATE SECTOR DEVELOPMENT
 
    Thailand has a mixed economy, with almost all industrial and commercial
activity being owned and operated by the private sector and financial activity
being owned and operated by both the public and private sectors. The government
controls some portions of financial activity in Thailand and is responsible for
promoting the necessary infrastructure and a stable environment to foster
economic growth. The government operates most public utilities and some
industries but since 1983 the government has taken steps to liquidate, sell,
lease or contract out a number of government enterprise activities to the
private sector.
 
    Thailand has been one of the largest recipients of foreign direct investment
("FDI") in the Asia Pacific Region, with net direct foreign investment of 53,691
million Baht , 43,812 million Baht , 33,241 million Baht , 49,887 million Baht,
57,472 million Baht and 91,346 million Baht in 1992, 1993, 1994, 1995, 1996 and
1997, respectively. (The drop in 1994 resulted from increased borrowings through
the Bangkok International Banking Facility ("BIBF") and growing FDI of Thais in
several foreign countries, particularly China, ASEAN and Indochinese countries.)
During the 1990's, FDI has been concentrated in a large number of large
companies engaged in manufacturing industries, trade and construction. The
agricultural sector, on the other hand, received less than 0.1% of the total FDI
in 1996 and 1997.
 
    The government of Thailand permits foreign investment and established the
BOI in 1960 to be the focal point of the country's investment promotion. In
1977, the current Investment Promotion Act was passed, which provides for
guarantees, tax exemption and, if necessary, temporary protection to be accorded
to projects undertaking certain activities. Incentives are also provided for
export projects and those located in designated investment promotion zones. The
government, for example, has guaranteed against nationalization, state
competition or monopolization, duty-free government import of competing goods,
and unjustified price control, and, subject to certain restrictions, has
permitted foreign ownership of land, the entry and work of experts, skilled
workers and their families and repatriation of capital and remittance of
profits. Except for designated businesses in which foreign investment is
limited, including banking and service industries, Thai law otherwise permits
foreign majority investment and control of firms undertaking industrial or
commercial activities.

LABOR SITUATION
 
    In Thailand, the labor force includes Thais aged 13 and over. In 1997,
approximately 46% of the total labor force was employed in the agricultural
sector. Between 1991 and 1996, the labor force increased at an average annual
rate of 0.9% from 31.0 million to 32.4 million. The labor force totaled 32.6
million in 1997. The unemployment rate at the end of 1997 was estimated at 3.5%.
 
    A legal framework, which prescribes the procedures for union formation,
collective bargaining and dispute settlement, was established by the Labor
Relations Act of 1975. Laws relating to working conditions and the protection of
workers promulgated in 1972 are expected to be replaced by the Labor Protection
Act of 1998, currently expects to become effective in August 1998. Only a small
proportion of the work force is organized in labor unions. In 1991, the Thai
government enacted a law which prohibits unionization in all state agencies and
enterprises. However, labor associations are still permitted and serve a
corresponding function.
 
    The government has attended to the welfare of workers through job creation
programs in different areas of the country and periodic minimum wage adjustments
to mitigate the effect of price increases. Effective January 1, 1998, the
minimum wage was 162 Baht per day for the Bangkok metropolis, its five
surrounding provinces (i.e., Nakornpathom, Nonthaburi, Patumthani, Sumutprakarn
and Samutsakorn) and Phuket, 140 Baht per day for Pangnga, Ranong, Chiang Mai,
Chonburi, Nakornratchasima and Saraburi, and 130 Baht per day for all other
provinces.
 
FOREIGN TRADE AND BALANCE OF PAYMENTS
 
    Foreign trade plays an important role in the Thai economy. Notwithstanding
the diversification which has occurred since the early 1960's, Thailand's
exports are still influenced by fluctuations in world commodity prices, and its
imports are primarily structured by the requirements of a developing country.
 
    Thailand's current account deficit has increased since 1987 principally due
to a trade deficit, and Thailand's terms of trade have declined over the period.
Although exports have risen significantly, imports increased even more rapidly
during this period due to heavy foreign and domestic investment flows. A large
percentage of imports during the past five years have been capital goods.
However, uncertainty concerning protectionism, growing competition for market
share from other countries in the region and continuing fluctuations in world
commodity prices will continue to affect future growth in export earnings.
Tourism has been a major source of foreign exchange earnings for the country.
 
    Since 1993, credit growth has been fueled by both deposits and external
borrowing through the BIBF. The cheaper cost of foreign currency loans
accessible through the BIBFs, coupled with the perceived absence of exchange
rate risk owing to a fixed exchange rate system, generated greater credit
demand.
 
    The large current account deficits over the past three years have been
financed by increases in direct investment, portfolio investment and external
borrowing. The net capital inflows in the past have more than offset the current
account deficits, resulting in a balance of payments surplus and a substantial
increase in the country's international foreign exchange reserves, from
U.S.$20.0 billion in 1992 to U.S.$37.2 billion in 1990, equivalent to
approximately 6.3 months of estimated 1996 imports.
 
    Since 1996, the real estate sector and the stock market have been weakening.
The export market has also become less competitive due to an over valued Baht
and higher labor costs. These market conditions created a general lack of
confidence among depositors and creditors, both domestic and foreign and
therefore lead to capital outflows. In the first half of 1997, the balance of
payments was negative U.S.$7.5 billion.
 
    In September 1997, strong export performance, aided by the depreciation of
the Baht, and a dramatic decrease in imports caused a trade surplus of 1.1
billion Baht. This was the first trade surplus of Thailand in decades. September
exports grew by 8.7% in U.S.$ terms over exports in September, 1996, while
imports
 
                                      A-9

for the same period shrank by 12.2%. Growth in exports of high technology
products, such as computers, computer parts, electrical circuits and plastic
products was noteworthy. October saw an estimated trade surplus for the month of
5.3 billion Baht and for November an estimated surplus of 27.3 billion Baht. The
current accounts deficit narrowed to Baht 3.9 billion in September. In 1997, the
current account deficit declined significantly to 2.0% of GDP. For the first two
months of 1998, the current account recorded a surplus of US$2.7 billion.
 
    The government has introduced a number of measures to reduce the current
account deficit with emphasis upon export promotion rather than constraints on
imports. A value added tax of 7%, intended to reduce distortion in the tax
system and encourage more efficient export oriented production was introduced on
January 1, 1992 and was increased to 10% in August 1997. As of early February
1998, the BOI was planning to seek cabinet approval to set up a loan guarantee
body as a mechanism aimed at a liquidity crunch facing exporters and the
agricultural industry.

SOURCE: THE BANK OF THAILAND MONTHLY BULLETIN, JUNE 1997.
 
    The large current account deficits over the past three years have been
financed by increases in direct investment, portfolio investment and external
borrowing. The capital inflows have more than offset the current account
deficits, resulting in a substantial increase in the country's international
reserves. The country's international reserves were significantly reduced in the
first half of 1997 in connection with the Bank of Thailand's attempt to maintain
a pegged exchange rate prior to July 2, 1997.
 
EXTERNAL DEBT
 
    Thailand's external debt, both public and private (including short-term)
grew from U.S.$5.7 billion in 1980 to U.S.$25.1 billion in 1990 and to U.S.$91.8
billion at the end of 1997. As of February 1998, the total amount of Thailand's
external debt was US$89.7 billion. It is estimated that substantially all of the
external debt is denominated in U.S.$ and yen. Debt servicing obligations
expressed as a percent of exports of goods and services declined from 14.8% in
1980 to 10.8% in 1990 but increased to 15.8% in 1997 due principally to
increasing levels of private sector external debt.
 
    Foreign borrowings have been on the rise since 1993, due to the commencement
of BIBF in March 1993, prompting subsidiaries of foreign companies to resort to
this new source of funds instead of bringing in foreign direct investment from
their parent companies or regional offices. Since borrowings through BIBF are
regarded as overseas obligations, Thailand's foreign debts have risen
accordingly.
 
                                      A-10

    Thailand's private sector is anticipated to face difficulty in payment of
approximately U.S.$39 billion of short term foreign debt falling due in 1998
although a significant amount of such debt has been voluntarily rolled over on a
short-term basis.
 
    As of mid-February, 1998, the Overseas Economic Cooperation Fund of Japan
was considering providing additional foreign currency loans to the Thai
government in order to boost liquidity. In late February, the president of the
Thai Export-Import Bank estimated that loans from international agencies would
add over 30 billion Baht of liquidity for Thai exporters within several months.
 
CURRENCY AND FINANCIAL SYSTEM
 
    The Bank of Thailand was established in 1942 as the central bank and is in
charge of implementing monetary policy.
 
    The Bank of Thailand is managed by its Court of Directors which is presently
composed of 10 members, with the Governor to serve as ex-officio Chairman and
two Deputy Governors to serve as Vice-Chairmen. The Governor and the Deputy
Governors are appointed by the King upon the recommendation of the Cabinet after
being nominated by the Minister of Finance, and other members of the court are
appointed by the Cabinet on the advice of the Minister of Finance.
 
    The principal functions of the Bank of Thailand are to act as (1) the
note-issuing authority on behalf of the government, (2) banker to the
government, commercial banks and other financial institutions, and (3) the agent
of the government to manage public debt, to administer exchange controls, to
supervise commercial banks, finance companies, and credit foncier (mortgage
lending) companies, and to deal with multinational monetary organizations. With
respect to exchange rate policy, the Exchange Equalization Fund, founded in 1955
and chaired by the Minister of Finance, is the agency of the government to carry
out exchange rate policy and foreign exchange transactions with banks.
 
    There are 36 commercial banks in Thailand of which 21 are foreign
incorporated banks. As of December 31, 1997, estimated total deposits of
commercial banks were 4,229 billion Baht compared to approximately 3,533 billion
Baht as of December 31, 1996. This represents an increase of 19.7%. Within the
public financial sector there are specialized banking institutions, including
the Government Savings Bank which is the principal institution for small savings
deposits, the Bank of Agriculture and Agricultural Co-operatives which is the
chief source for farm credits, the Government Housing Bank which provides
mortgages to middle and low income individuals, and the Small Industries Finance
Office which advances loans to companies with registered capital or fixed assets
of up to 10 million Baht (U.S.$384,763).
 
    As of March 31, 1998, 52 financial institutions held licenses to operate
offshore banking business through BIBF's. Of these, 15 belong to Thai commercial
banks, 18 to foreign bank branches already operating in Thailand, and 19 to
other foreign banks. As of March 31, 1998, 48 BIBF offices had commenced
operations.
 
    In January 1995, 22 commercial banks were granted permission to operate
Provincial International Banking Facilities ("PIBF") offices. At the end of
1996, 37 PIBF's had begun operations in five different provinces including
Chonburi, Rayong, Ayutthaya, Chiang Mai and Songkhla. In January 1997, seven
foreign banks holding BIBF licenses were granted permission to open full
branches, and an additional three new bank licenses have been provisionally
granted to allow the establishment of new domestic banks.
 
    As of January 1, 1995, the capital adequacy framework of the Committee on
Banking Regulation and Supervisory Practices of the Bank of International
Settlement was fully adopted in Thailand's banking system, which brought the
Thai commercial banks in line with international standards.
 
    Against the background of sizeable non-performing loans carried by some of
the finance companies in their loan portfolio and the liquidity crisis
experienced by all of the finance companies, the Ministry of Finance in July and
August 1997 ordered 58 finance companies to suspend their operations, including
 
                                      A-11

suspension of trading of the suspended companies' shares on the SET, pending
approval of the rehabilitation plans submitted or to be submitted by the
suspended companies. On December 8, 1997, the Ministry of Finance ordered the
closure of 56 out of the 58 suspended finance companies resulting in an
estimated 20,000 employees losing their jobs. The Association of Finance
Companies believes that strong pressure on the remaining 35 finance companies
may induce mergers in the industry. The remaining finance companies will have to
comply with a higher capital fund to risk assets ratio and other similar rates.
They will also face competition from investors in the sector. The liquidity
crisis and overall lack of confidence in the financial sector by the public are
also felt by smaller commercial banks in Thailand. Depositors reportedly are
transferring their deposits from the smaller banks to larger Thai banks and
local branches of foreign banks. Recent disruption in the finance and property
sectors has severely affected certain property firms, the finance sector and, to
a lesser extent, the banking sector.
 
    On November 6, 1997, the National Assembly passed four emergency decrees the
main purposes of which were to restore confidence and to provide direction and
stability in the financial system. Two of the decrees authorized the creation of
the FRA and the Asset Management Corporation ("AMC"). The objectives of the FRA
are to review the rehabilitation plans of suspended finance companies, to assist
bona fide depositors and creditors of suspended finance companies and to
administer the liquidation of finance companies which cannot be rehabilitated.
Six board members of the FRA were appointed to oversee the work of the FRA. As
of early February 1998, the FRA anticipated auctioning the assets of the closed
finance companies in early March 1998 and complete liquidation of the assets of
the 56 closed finance companies by year end 1998. The primary objective of the
AMC is to bid for the assets of those finance companies that the FRA deems
nonviable. The other emergency decrees amended the Bank of Thailand Act, the
Commercial Banking Act and the Act on the Undertaking of Finance, Securities and
Credit Foncier Business (the "Finance Act"). The new decrees give the Bank of
Thailand, under certain circumstances, new powers to intervene in the operation
of financial institutions. These powers include the power to remove directors or
executives of such financial institutions and to appoint replacement directors
or executives. Finally, the decree amending the Bank of Thailand Act reaffirms
the government's commitment to a government subsidized institution, the FIDF,
that will provide certain guarantees to depositors and creditors. One of the
most important features of the decree amending the Bank of Thailand Act is that,
if necessary, the FIDF can release the collateral pledged to the FIDF by
suspended finance companies. This will allow all creditors of such finance
companies to receive equal treatment.
 
    The AMC is anticipated to have severe funding problems because the total
cost of buying problem assets of the 56 closed finance companies is now
anticipated to be much higher than originally thought. Such estimates range from
200 billion Baht to 700 billion Baht. AMC start-up capital is 1 billion Baht.
 
    In late February, an independent investigation by the Finance Ministry found
that FIDF was likely to write-off at least half of the 800 billion Baht in loans
extended to ailing financial institutions. This expected loss is estimated to
equal the total value of assets held by the Bank of Thailand.
 
    The Bank of Thailand has recently changed capital adequacy requirements
applicable to commercial banks and finance companies based on Bank of
International Settlement requirements. Because of these tough new capital
requirements, surviving finance companies are anticipated to seek substantial
increases in capitalization. Commercial banks will also feel the impact of the
new capital requirements and, according to recent press accounts, are seeking to
sell equity interests to foreign shareholders. In late February, 1998, two of
Thailand's larger banks announced plans to boost capital. In December 1997, the
Bank of Thailand replaced the boards of directors of two smaller banks, First
Bangkok City Bank and Bangkok Metropolitan Bank, in order to encourage these
banks' capital increase programs. In early February, 1998, IMF officials
reportedly characterized the local commercial banks as remaining "relatively
weak".
 
    On February 6, 1998, the Bank of Thailand announced the formal takeover of
three ailing Thai commercial banks: the Siam City Bank Public Company Limited,
First Bangkok City Bank Public
 
                                      A-12

Company Limited and the Bangkok Bank of Commerce. The move resulted in the
elimination of all shareholders' equity in the three banks by ordering a massive
capital write-down to clear bad debt. The central bank's Financial Institutions
Development Fund ("FIDF") will swap its loans to the three banks for an equity
stake, becoming near 100% shareholder which will, in effect, turn the three
banks into state enterprises. The government is currently developing plans to
privatize these banks during 1998.
 
    This action was similar to the decision by the Bank of Thailand in
mid-January when it ordered the Bangkok Metropolitan Bank Public Company Limited
to write off 11 billion Baht of its capital, reducing the par value of shares to
one one-hundredth of a Baht each. The FIDF will take a 99.96% stake in the bank
after the capital is increased by 25 billion Baht.
 
    On May 18, 1998, the Bank of Thailand ordered seven additional finance
companies, with total assets of approximately Baht 92.2 billion, representing
approximately 15% of the total assets of operating finance companies, to
write-down their capital and announced that the FIDF would recapitalize six of
the seven finance companies by converting into equity approximately Baht 10.84
billion of debt owed by such finance companies to the FIDF and injecting
approximately Baht 620 million of additional capital into the seventh finance
company. The recapitalization is expected to raise the capital-to-risk assets
ratio for all seven companies to at least 9%. The Bank of Thailand also replaced
the board of directors of each company with representatives of the Bank of
Thailand and Krungthai Thanakit Public Company Limited ("KTT"), a subsidiary of
Krungthai Bank Public Company Limited. The Bank of Thailand intends that KTT
will acquire the assets and assume the liabilities of each of the seven
companies, which eventually will be consolidated into KTT. If necessary, the
FIDF may also assist in recapitalizing KTT by providing additional equity
capital. KTT is also expected to be granted a commercial banking license in
connection with such consolidation and recapitalization.
 
    In addition to the Emergency Decrees, in May 1998, the National Assembly
approved five additional emergency decrees with the objective of increasing
liquidity in the Thai economy and expediting the resolution of the financial
sector crisis. These decrees (i) authorize the Government to incur, by no later
than December 31, 2000, external borrowings not to exceed Baht 200 billion in
addition to its authorized external borrowing limits (which are currently set at
a maximum annual limit of 10% of the Government's
annual budget, (ii) authorize Government domestic borrowing of up to Baht 500
billion to refinance the FIDF's short-term borrowings, (iii) exempt the FIDF
from certain bankruptcy law provisions which prevent creditors who have
knowingly provided financial assistance to insolvent financial institutions from
filing debt repayment claims against such financial institutions, (iv) modify
the AMC's charter to permit increased capital and (v) specify procedures for the
sale of assets of closed finance companies by FRA.
 
    The new Bank of Thailand governor, M.R. Chattumongkol Sonakul, has announced
that no financial institution will be ordered to close. However, financial
institutions with serious problems will be compelled to reduce their capital and
be taken over the the FIDF.
 
MONETARY POLICY
 
    The Bank of Thailand is responsible for controlling the money supply in
Thailand. In furtherance of the country's objective of becoming the financial
center of this region, several financial liberalization policies have been
adopted, including the introduction of BIBF, which permit banks to make loans in
currencies other than Baht, and the relaxation of rules and regulations on the
movement of capital. These liberalization policies may have the effect of
impairing the ability of the authorities to control capital inflows, money
supply, and inflation in the foreseeable future. However, in early February
1998, IMF officials suggested that the reduction of relatively high interest
rates be delayed in an effort to prevent inflation.
 
    Due to an increasingly open economy, external conditions have become
important factors affecting Thailand's economy. During the early 1980's when the
world economy suffered an economic downturn, which caused worldwide reduction of
inflation and declining investment, the country's GDP growth fell to
 
                                      A-13

around 5.5%. However, since the mid 1980's the world economy has improved and
conditions in trade and investment have changed rapidly. Among other things, the
substantial amount of foreign investment, particularly from Japan, was one of
the major forces behind the economic boom during 1987-1990.
 
FOREIGN EXCHANGE REGULATION
 
    Throughout the first half of 1997, the Bank of Thailand had been actively
intervening in the foreign exchange markets in order to support the Baht against
the selling pressures of heavy speculation in the markets. However, on July 2,
1997, the former Minister of Finance, Thanong Bidaya, upon the recommendation of
the Bank of Thailand, allowed for the floatation of the Baht by repealing the
November 2, 1984 act which had pegged the value of the Baht against a basket of
currencies. The value of the Baht is now set by conditions in the foreign
exchange markets. The Bank of Thailand engages in the buying and selling of
foreign currency for the purpose of maintaining the stability of the Baht under
the new foreign exchange system. Foreigners and non-resident bank clients are
restricted from buying or selling U.S.$ for speculative purposes.
 
    On August 21, 1997, the Bank of Thailand announced that the bulk of the
official reserves of U.S.$30.0 billion as at end-July had already been sold
forward, with U.S.$23.4 billion falling due within the next 12 months. The Bank
of Thailand's Economic Research Department disclosed that on November 14, 1997,
Thailand's foreign reserves dropped to U.S.$28.3 billion and U.S.$26.3 billion
in the following two weeks. At that time, U.S.$10.6 billion in offshore forward
obligations were still outstanding from the U.S.$14.8 billion in offshore
forward transactions taken out in May, 1997. Outstanding forward obligations
taken in the onshore market for 1997 total about U.S.$8 billion. The Bank of
Thailand maintains a foreign reserves target for 1997 at U.S.$23 billion and for
1998 at U.S.$24.8 billion.
 
    On January 6, 1998, the Thai Cabinet approved the issuance of a Ministry of
Finance regulation to limit the U.S. dollar holding period for exporters in an
effort to curtail currency speculation and increase the U.S. dollar supply in
the local economy. According to the ministerial regulation, exporters must now
bring their earnings into Thailand immediately upon payment, after which, they
have seven days to either sell to or deposit their dollars in a foreign currency
account with an authorized Thai commercial bank. Previously, the Bank of
Thailand provided that exporters had 120 days in which to receive payment for
their goods and bring the money into the country, after which, they had a
further 15 days to deposit it.
 
    As of January 30, 1998, the restrictions underlying the two-tier system were
lifted, and financial institutions may engage in spot foreign exchange
transactions involving Baht with non-residents. In addition, the restrictions on
transfers of Baht in connection with the sale by non-residents of Thai
securities were also removed. To discourage speculative activity, Baht
denominated credit facilities to non-residents are limited to a maximum amount
of Baht 50 million per counterparty in cases where there are no underlying trade
or investment activities in Thailand.
 
IMF-LED FINANCIAL ASSISTANCE
 
    The Government agreed on August 5, 1997, to accept austerity measures of the
IMF aimed at rehabilitating and restructuring the economy as a condition to
receipt of IMF-led loans and financial assistance of approximately U.S.$17.2
billion. Key rehabilitation goals are:
 
    - restore fiscal, monetary and economic stability immediately,
 
    - maintain foreign exchange reserves equal to 3.5 months import value or a
      minimum U.S.$25 billion,
 
    - restore confidence and trust in the finance and banking system to counter
      any run on deposits. restructure the FIDF's role to ease the burden on the
      government,
 
    - cut the current account deficit from 8% of GDP in 1996 to 5% in 1997 and
      3% in 1998,
 
    - maintain annual economic growth at 3-4% in 1997 and 1998,
 
                                      A-14

    - cap inflation at 8-9% in 1997,
 
    - continue with the balanced budget policy to maintain fiscal stability.
 
    - Tackle economic problems and build international credibility through
      financial and technical assistance from the IMF and foreign financial
      institutions.
 
    On August 20, 1997, the IMF approved a stand-by arrangement for Thailand,
authorizing drawings of about U.S.$3.9 billion over the next 34 months to
support the government's economic program, and in particular, its international
reserve position. Of the total, about U.S.$1.6 billion was available
immediately, and a further U.S.$810 million will be available after a review of
program implementation on December 8, 1997. The total amount of funds provided
by the IMF under the package since August 1997 has been U.S.$2.4 billion.
 
    On October 14, 1997, the government of Thailand announced measures related
to the fiscal year 98 fiscal surplus target agreed to with the IMF, and to the
financial sector restructuring task ahead. On the fiscal front, the Council of
Ministers approved 1400 billion Baht of measures, including excise tax increases
of 400 billion Baht and spending cuts of 100 billion Baht, 70% of which are to
come from public investment projects. With these measures the authorities
believe the 1% of GDP fiscal surplus originally agreed with the IMF can be
achieved. In February, 1998, the government announced additional excise tax
increases, and, in response to a general perception that Thailand's economic
condition has stabilized, relaxed loan package requirements to allow the state
enterprise sector to run a budget deficit of 0.5%.
 
FISCAL UPDATE AND FINANCIAL SECTOR MEASURES
 
    In the first 11 months of fiscal year 1997, the government budget was 60.6
billion Baht in deficit, an amount above the IMF target of 52.8 billion Baht for
the year. To provide a 1998 budget surplus, the government on August 16, 1997,
put into effect an increase in value added tax ("VAT") from 7% to 10%. The
Revenue Department said such an increase would generate an additional revenue of
Baht 70 billion per annum. In addition, the government reduced its 1998 budget
by 59 billion Baht to 923 billion Baht.
 
    As a first step in reforming and strengthening the country's financial
sector, the Council of Ministers on June 24, 1997, approved four decrees aimed
at restructuring the country's financial sector, and boosting liquidity. The
first decree amended the Commercial Banking Act to allow foreign investors to
hold shares in local banks in excess of the existing 25% limit. The second
decree amended the Finance Act to eliminate several obstacles to mergers among
the financial institutions. Companies are now permitted to transfer debt rights,
without having to notify borrowers, thus speeding up the merger process. The
third decree formalized securitization, with special institutions authorized to
accept assets and issue securities. The fourth decree established a secondary
mortgage corporation, which develops a secondary market for property loans.
 
    As a result of these reforms, Citibank has entered into negotiations to hold
at least 50.1% of the paid up capital of First Bangkok City Bank Plc, a
medium-sized bank. China Development Corporation of Taiwan has shown interest in
buying a 2% to 3% stake in Bangkok Bank Plc, Thailand's largest bank.
 
    On June 27, 1997, the central bank suspended the operations of 16 finance
companies, and ordered them to merge with core finance companies or seek strong
partners. The authorities ordered these companies to prepare rehabilitation
plans and provided depositors with promissory notes in the amount of their
deposits. After the mergers, promissory-note holders are expected to be able to
reclaim their deposits from the new firms. Furthermore, promissory-note holders
are also expected to be able to discount their promissory notes in the secondary
bond market, use them as collateral for loans or exchange their notes for a
certificate of deposit at Krung Thai Bank.
 
    On August 5, 1997, the Thai government suspended an additional 42 finance
and securities companies, bringing the number of suspended finance firms up to
58. The Government said it will protect
 
                                      A-15

depositors and "bona fide" creditors of the 42 suspended firms, with the option
of exchanging promissory notes and certificates of deposit with Krung Thai Bank,
which is 60% owned by the Finance Ministry. In late November, 1997, the Bank of
Thailand suspended an additional finance firm.
 
    On October 14 new financial sector measures were announced including:
liberalization of the restrictions on foreign participation in the sector,
creation of the AMC, which is to take over, manage and sell bad debts of
financial institutions, the creation of the FRA, which is to regulate financial
institutions and guarantee depositors and other creditors, the introduction of
higher capital requirements and higher provisioning requirements for bad loans,
and the amendment of the bankruptcy laws to make it easier to seize collateral.
 
    On December 8, 1997, the Finance Minister, on the recommendation of the FRA,
announced that only two of suspended finance firms would be allowed to reopen,
and the other 56 suspended firms were ordered closed. The good assets of the
closed finance companies would be transferred to a so-called "good bank," which
was set up in February 1998. Bad assets will be transferred to AMC for
management. Creditors and depositors of closed finance companies have the option
to convert their claims into Krung Thai Bank's certificates of deposit or, as
the case may be, Krung Thai Thanakit Finance and Securities Plc's promissory
notes. The government regulation also prevented the resale of notes held by
depositors. This prevented the resale of these notes at a discount in secondary
capital markets. This has resulted in liquidity problems for depositors.
 
    In May 1998, the Ministry of Finance and the Bank of Thailand also adopted a
15-point program designed to increase liquidity in the Thai economy, including
(i) seeking additional multilateral and bilateral external financing, (ii)
issuing the Debt Securities offered hereby, (iii) improving the FRA auction
process for the assets of the 56 closed finance companies to attract foreign
buyers, (iv) accelerating the raising of capital by commercial banks from
foreign investors, (v) refinancing the FIDF's short-term debt through longer
term domestic borrowings, (vi) encouraging debt restructuring by Thai commercial
banks and their clients, (vii) revising macroeconomic assumptions under the IMF
Financial Assistance Program, (viii) encouraging the restructuring of private
sector external debt, (ix) accelerating the increase of capital by Thai
commercial banks, (x) completing amendments to Thai bankruptcy and foreclosure
laws, (xi) encouraging foreign investment in domestic capital markets, (xii)
accelerating the privatization of state enterprises, (xiii) stabilizing the Baht
and the short-term money markets to facilitate lower interest rates, (xiv)
increasing hire purchase and housing credits, and (xv) timely payment by
Government entities to private sector contractors for services performed.
 
SOVEREIGN AND CORPORATE CREDIT RATINGS
 
    Moody's Investors Service, Inc. ("Moody's") has currently rated the Kingdom
of Thailand at Ba1, with a negative rating outlook, for its long-term foreign
currency debt, and not Prime for its short-term foreign currency debt, with a
credit watch for a possible downgrade. Moody's has rated foreign currency bank
deposits at B1, with a stable outlook, and short-term foreign currency bank
deposits at not Prime. At the same time, the country's ratings by Standard &
Poor's Corporation are currently BBB- for its long-term, foreign currency debt
rating, and A-3 for its commercial paper and short-term, foreign currency debt,
with a negative overall outlook on foreign currency debt. Additionally, S&P has
a local currency rating on Thailand's long-term debt of A- with a negative
outlook and a short-term local currency credit rating of A-2.
 
    In recent months, various rating agencies have steadily down-graded Thailand
related investments. On April 9, 1997, Moody's downgraded the foreign currency
ceilings for bonds and bank deposits of Thailand from A2 to A3. The agency said
the downward adjustment reflected an incremental deterioration in the country's
creditworthiness stemming (1) from a build up of short term foreign currency
obligations that has contributed to the recent escalation of the country's
overall external debt ratios, (2) structural problems that have adversely
affected Thailand's competitiveness in its traditional manufactured export
industries,
 
                                      A-16

(3) constraints on the array and effectiveness of macroeconomic policies at the
government's disposal to respond to these challenges and (4) the crisis in the
domestic financial and property sectors.
 
    On September 3, 1997, S&P lowered its long-term, foreign currency rating of
the country from A to A-. At the same time, S&P lowered Thailand's long-term
local currency rating to AA- from AA. S&P said the downgrades reflected
substantial loan losses in the financial sector as well as the diminution of
Thailand's external financial flexibility.
 
    On October 2, 1997, Moody's cut its assessment of Thailand for a second time
that year and maintained a negative outlook, lowering Thailand's long-term
foreign currency country ceiling for bonds and notes and the long-term foreign
currency country ceiling for bank deposits from A3 to Baa1. Moody's said the
downgrades reflected an erosion of assets in the country's financial system
crippled by the slowest economic growth in 30 years, increased foreign debt
following a currency devaluation in July and problems in the property industry.
Moody's had placed these ratings on review for possible downgrade since
September 9, 1997.
 
    On October 24, 1997, S&P again lowered Thailand's long-term, foreign
currency rating to BBB from A- and its long-term local currency rating to A from
AA-. S&P cited weak political leadership as one of the factors for the
downgrade. S&P said the outlook on Thailand's long-term ratings remained
negative.
 
    On November 28, 1997, Moody's downgraded Thailand's ratings for long-term,
foreign currency debt from Baa1 to Baa3 with a negative rating outlook. Moody's
ratings for short-term foreign currency debt remained at Prime-3 under a credit
watch for possible downgrade. Moody's also lowered Thailand's ratings for
foreign currency bank deposits from Ba2 to B1, with a stable outlook. Short-term
foreign currency bank deposits remain unchanged at Not Prime. Moody's maintained
that the downgrades reflected the deterioration in Thailand's credit and
financial fundamentals and concerns that domestic political conditions would
limit the Thai government's progress in meeting conditions of the IMF
stabilization program.
 
    On December 21, 1997, Moody's again downgraded Thailand's rating for foreign
currency debt from Baa3 to the current Ba1.
 
    On January 9, 1998, S&P lowered Thailand's long-term, foreign currency
rating to BBB- from BBB, long-term local currency debt rating to A- from A, and
the short-term local currency debt rating to A-2 from A-1. In making the
downgrades, S&P predicted a 3% economic contraction in 1998 and cited high
interest rates, depreciation of the Baht and the high proportions of
non-performing loans in bank and finance company portfolios.

      EVALUATION OF OPERATING COST AND PRODUCTION CAPACITY PROJECTIONS OF
                  NAKORNTHAI STRIP MILL PUBLIC COMPANY LIMITED
 
                                      B-1

INTRODUCTION
 
    Nakornthai Strip Mill Public Company Limited (NSM) is in the final
construction/commissioning of the first stage of its flat rolled mini-mill
located at Chonburi Industrial Estate, Thailand. Construction of the first
stage--electric arc furnace (EAF)--ladle metallurgy--compact strip production
(CSP) is nearly complete, with first production from the EAF scheduled for late
November 1997. The second stage--coal based DRI--pickling--galvanizing--cold
rolling is just commencing construction.
 
    Nakornthai Strip Mill Public Company Limited engaged Hatch Associates, Ltd.,
Toronto, Canada to provide an independent evaluation of their projections for
operating costs and production capacity for the first and second stages of its
facility. The operating cost and production tonnage projections were contained
in the document "McDonald & Company Securities, Inc.", dated October 29, 1997.
Information concerning unit pricing, unit consumptions, equipment specifications
and process productivity was obtained from various documents examined during a
site visitation in late October, 1997. Where possible, contracts or purchase
orders were examined to verify prices of consumables and raw materials.
Productivity of potential "bottleneck" units were examined in greater detail
than other areas since these would be key to achieving the expected capacity.
 
SUMMARY OF FINDINGS
 
FACILITIES
 
    The NSM facilities contain (or will soon contain) a rather unique
combination of U.S. flat rolled mini-mill technology and operating philosophy
along with process equipment and technologies more frequently associated with
speciality or higher quality steel producers. The equipment is definitely
"State--of--the-- Art", with a good deal of it similar to that installed at
Nucor's Berkeley, South Carolina plant. Subtle changes in equipment design have
been made where appropriate, however, maintaining the spectra of proven
technology. The latest in level I and level II process control systems are being
installed and have incorporated functions critical to production optimisation.
For example, the loading of scrap onto the Consteel conveyor will be dynamically
monitored and displayed to the scrap loaders in order to insure that scrap feed
to the EAF, which is so critical to this process, is optimised.
 
    The coal based DRI process, lnmetco, will take advantage of iron ore fines
and coal to produce a lower cost iron unit than available from the international
market. The DRI facility will have the capacity to fulfill approximately 30% of
NSM's iron unit requirements. The ladle metallurgy facilities at NSM--ladle
furnaces and vacuum tank degassing--will obviate disadvantages (namely sulfur
from the coal carried into the steel) which may otherwise be associated with the
Inmetco process.
 
    A waste heat generation facility is also planned. This facility would
generate electricity from waste gases from the DRI and EAF processes and will
significantly reduce NSM's overall energy costs.
 
    The EAF will contain the latest in Consteel technology, utilizing the
furnace off--gases to preheat scrap, thereby reducing energy consumption and
scrap melting time. The EAF is also equipped with electric energy reduction
technologies such as large capacity oxygen and carbon injection and submerged
tuyeres for light oil injection.
 
    The ladle metallurgy furnaces and vacuum tank degassers will assist in the
production of high quality steels as well as to provide a buffer between the EAF
and the continuous caster.
 
    The continuous caster and hot strip mill (CSP) will be of SMS' most recent
design. The caster will incorporate "soft reduction" and electromagnetic brake (
EMBR ) technologies to enhance productivity and reliability.
 
    The hot strip mill will contain the latest in work roll shifting and
bending, hydraulics and gauge and shape control.
 
                                      B-2

    The pickle / galvanizing line will target a particular market and contains
equipment (cold reduction, skin passing, tension leveling) seldom seen, even in
new facilities.
 
PRODUCTIVITY
 
    The projected capacity of the facility is 1.35 million tonnes per year of
hot rolled coils. At a yield of 95% from liquid steel to hot rolled coil, this
equates to 1.42 million tonnes per year of liquid steel. The steelmaking
facilities--Consteel--EAF--ladle furnaces--vacuum degassers should have little
difficulty in achieving this production level. In addition to NSM's own
knowledgeable staff of steelmakers, advisors from Nucor experienced with the
Consteel process will be available during start up.
 
    The continuous caster should also be capable of producing at the 1.35
million tpy rate provided that NSM's product mix does not have an inordinately
high percentage of steel in the narrower width ranges, otherwise production
capacity will suffer.
 
    The start up expectations--651,000 tonnes in year 1 (48% of capacity) and
1,232,000 tonnes in year 2 (91 % of capacity)--are well within the range of
historical start-up curves and should be achievable considering the expertise
available and the training of the personnel.
 
OPERATING COST
 
    The operating costs, once all of the equipment is installed and operating at
capacity, are projected to be:
 


THROUGH PROCESS UNIT                                                       OPERATING COST $/MT
- -------------------------------------------------------------------------  -------------------
                                                                        
DRI......................................................................           84.98
EAF--Melt Shop...........................................................          202.91
Cast Slab................................................................          215.23
Hot Rolled Coil..........................................................          231.68
Pickled & Oiled Coil.....................................................          248.41
Galvanized coil..........................................................          307.04
Sales, General & Administration..........................................           +8.41

 
    These costs were calculated at an exchange rate of 45.5 Baht:1 $US.
 
    Raw materials and energy comprise approximately 70% of the operating costs
and were examined closely. Electrical energy consumption at the plant is aided
significantly by the planned installation of a waste heat generation facility
which will supply 44 MW of capacity and which will reduce the amount purchased
of electricity by nearly $17 million per year (approximately $12.50/tonne).
 
    Prices for iron ore and coal for the DRI plant have been established through
contractual agreements. Unit costs for other consumables are in line with
international prices. Unit consumptions for energy, electrodes, refractories,
etc. are neither optimistic nor conservative and are representative of the
employed technology.
 
    NSM expects that by year 2001, sufficient domestic scrap will be generated
such that all of its scrap needs will be accommodated from within Thailand. In
our opinion it remains uncertain whether the domestic scrap market will be
sufficient to accommodate 100% of NSM's scrap needs by the year 2001. However,
we also believe that NSM's projected scrap prices--$178/MT for imported scrap
(delivered to site) and at $150/MT for domestic scrap (delivered)--are
conservative, particularly the price for domestic scrap. High quality domestic
scrap is priced in the $100-120/MT range as of late October 1997. Therefore we
feel that NSM's projected price of $150/MT is very conservative, particularly
considering that domestic scrap is traded in Baht. These factors--a lower priced
domestic scrap and a need to import more scrap than planned--will likely offset
each other, resulting in an overall raw material cost which is as stated in
NSM's projections.
 
                                      B-3

    In the initial review of the operating cost projections, it appeared as
though certain inefficiencies in consumption of energy and other consumables was
not thoroughly accounted for during the start up period--first 2 years, although
lower yields during the start up phase were acknowledged. Projections concerning
these inefficiencies, which are quite normal during start up, were recently
provided to NSM.
 
OVERALL SUMMARY
 
    NSM's projections of operating cost and production capacity are very
realistic. NSM's flat rolled mini-mill will have State--of--the--Art equipment
which emphasizes the production of quality steel products while concurrently
minimizing energy consumption and yield losses. Such a facility configuration is
critical to success in the South East Asian area where energy and iron unit
costs are generally higher than in other steel producing regions of the world.
 
    The only projection with a degree of uncertainly concerns the capability of
the continuous caster to support 1.35 million tpy if the product mix contains an
inordinately high percentage of narrow product. The market is likely not yet
defined well enough to resolve this issue, however, the productivity penalty, if
any, would be modest at worst.

                    THE OUTLOOK FOR STEEL SHEET PRODUCTS IN
                                SOUTH EAST ASIA
 
    The following provides a brief overview of the outlook for steel sheet
products in Thailand, Malaysia, Indonesia, the Philippines, South Korea and
Taiwan over the period 1991 to 2005.
 
INTRODUCTION
 
    Steel consumption in the South East Asian region has seen double digit
growth over the last fifteen years, compared with virtually no growth in the
mature economies of Japan, North America and Western Europe. This trend is
likely to continue for the foreseeable future, though recent macroeconomic
developments and currency turmoil in all the Asean countries will dampen growth
prospects for the next couple of years. In the medium term, we expect the region
to remain the fastest growing steel market in the world with steel demand
growing at an annual average of 6-8%. This will provide substantial
opportunities for investment in steel making and rolling facilities to replace
the growing flow of imports into the Asean region from all over the world, from
such places as Japan, India and Russia.
 
    Korea and Taiwan dominate the region in terms of production and consumption
of sheet products, having established integrated steelmaking facilities and
substantial export markets for their products. Though relatively small in size,
many of the Asean countries have seen strong growth in steel consumption,
exceeding an average of 10% per year between 1980 and 1995. With the exception
of Indonesia, the Asean countries all rely heavily on imports, particularly of
steel sheet products, to meet their growing demand requirements. As these
markets have grown, several major new steel making facilities have come on
stream or are planned to do so in the next two years which will substantially
reduce the current dominance of imports.
 
    Though the medium term economic prospects remain good, there has been some
slow down in the region recently. In 1996, industrial production growth rates in
a number of the Asean countries slowed as the region suffered a slow down in
manufacturing exports. Growth rates are expected to slow further this year in
response to the currency markets turmoil evident since early July. This
development continues to create uncertainty and make investors more cautious.
The devaluations against the dollar have had the immediate effect of reducing
regional import demand for steel products. Thailand and to a lesser extent
Indonesia are more severely affected, but Malaysia and the Philippines have also
reduced import levels in recent months in response to the rising dollar.

    Uncertainty caused by the crisis has reduced steel trading activity with
buyers deferring purchases and sellers not extending terms of credit. In our
forecasts, we have assumed that this crisis is likely to have repercussions for
steel consumption in the region for 1997 and 1998 but that demand will recover
more strongly in 1999 and beyond.
 
    Steel sheet products, hot-rolled, cold-rolled and metallic coated sheet and
coil, which are the markets that NSM will be competing in, account for just
under 40% of total steel product consumption in the Southeast Asian region. The
other 60% or so is primarily reinforcing bar and other long products used in the
construction industry. As these markets develop and the population's prosperity
rises, the demand for consumer durables, such as automotives and consumer
durables, will raise the share of sheet products in total steel consumption.
 
    In order to assess the market opportunities for Nakornthai Strip Mill (NSM)
and the competitor behaviour of existing and new steel sheet producers over the
next ten years, we look at each of the countries of the region in turn. The
accompanying tables provide our estimates of historical and forecast
consumption, production and capacity of hot-rolled, cold-rolled and coated sheet
in each of the major markets discussed. According to our forecasts, total sheet
consumption is forecast to grow robustly at an annual average of 8.2% in
Thailand and 7.4% in the six major consuming countries of the region between
1997 and 2005.
 
THAILAND
 
    In 1996, Thailand consumed about 4.6m tonnes of sheet products and imported
3.3m tonnes. The sheet market has been growing rapidly over the last five years,
at an annual average rate of 9%. However, growth slowed in 1996 to 4.6%, down
from more than 14% per year in the previous two years. The collapse of the baht
is expected to have a noticeable impact on steel demand in 1997 and 1998.
Imports will fall and domestic producers will face reduced demand and difficulty
in passing on fully the effects of the devaluation in higher baht prices. We
believe that sheet demand could fall almost 9% this year, partially recovering
in 1998 to reach 4.4m tonnes. From 1999, assuming the impact of the currency
crisis has worked through the system, sheet demand is forecast to pick up
strongly growing by as much as 10% per year, so that we estimate that growth of
just over 8% average over the forecast period to 2005.
 
    Sahaviriya Steel Industries is currently the only hot strip producer,
rolling imported slab. It sources its slab from a variety of mills, most
recently from the CIS (Commonwealth of Independent States) and Eastern Europe,
and these varied sources have affected its ability to supply a consistent
quality product. NSM is expected to bring on stream its 1.5m tpy hot strip
mini-mill at the beginning of 1998 and the Japanese joint venture, Siam Strip
Mill, will follow within a year with a further 1.7m tpy of hot rolling capacity.
By the time both of these mills are fully running, Thai demand for hot-rolled
coil (including that for further processing into cold-rolled) is likely to reach
around 5 5.5m tonnes. Hence, these new producers should find good opportunities
in their domestic market for import substitution. Both new producers are making
provision to expand capacity in the longer term.
 
    Thailand has not produced cold-rolled coil to date and imports between 1.5
and 2m tpy. Now there are two new cold mills, Thai Cold-Rolled, which has
recently come on stream and Siam United Steel, which is under construction, with
a joint capacity of 2.2m tpy. Both mills are Japanese joint ventures which are
likely to source the majority of their mother coils from Japan to supply high
quality cold-rolled to Japanese OEM (original equipment manufacturers)
transplants in Thailand and other Asean. BHP Steel (The Broken Hill Proprietary
Company Limited) is installing a 300,000 tpy cold mill and 150,000 tpy
galvanising line. The cold-rolled produced on this mill will be galvanised at
the same location or shipped to Indonesia to the other BHP galvanising line
there. Currently Thailand imports almost half of its coated

                              RESOURCE STRATEGIES
 
sheet requirement of almost 1m tpy. This situation should change over the next
five years as NSM brings on 500,000 tpy of galvanising capacity and several
other smaller lines come on stream. By the end of the forecast period, Thailand
could be a net exporter of hot-dipped galvanised sheet.
 
INDONESIA
 
    Indonesia consumed nearly 1.8m tonnes of sheet products in 1996, and its
consumption of sheet products has risen and fallen regularly over the last five
years, with an underlying trend of +4%. Prospects for future steel consumption
are good as economic growth is forecast to be strong. We are forecasting that
total sheet consumption will rise by 8.5% per year on average over the next nine
years.
 
    Krakatau Steel is a fully integrated steelworks established in 1986 which
produces around 1m tpy of hot-rolled coil and about 50% of the country's
cold-rolled production. The company is planning to expand capacity and may be
privatised to raise the necessary funding. One of the key stumbling blocks has
been on the choice of steelmaking route to supply the increase in capacity. In
1993, regulation of the industry was relaxed allowing investment in flat
products. Several foreign investors, most notably Posco of Korea and Yieh Phui
of Taiwan, are considering joint venture flat product facilities in Indonesia.
There are plans to install galvanising lines that will double existing capacity.
If all the announced planned projects come to fruition, their production is
likely only to meet the growth in domestic demand in the medium term.

                              Resource Strategies
 
MALAYSIA
 
    The Malaysian sheet market is currently about 2.1m tonnes, and has been
growing at an annual average of 7% in the last five years. It imports 100% of
its hot-rolled coil requirement as it has no hot rolling facility. There are
several proposed new mills, the most ambitious of which is the Megasteel
project, which will commission a 2m tpy hot rolling mill in 1998. It is likely
that the company will install further downstreaming rolling and coating at this
facility in the future. Nusantara Steel has recently announced that it aims to
start producing 1.6m tpy of hot-rolled coil in 1999.
 
    Growth in Malaysian sheet steel consumption is expected to be the strongest
in the region at an annual average of just over 9%. If this growth is realised,
Malaysia will remain a significant net importer of sheet steel unless further
projects are announced.
 
PHILIPPINES
 
    Philippine sheet steel consumption grew dramatically from very small volumes
over the last five years at an average rate of 11.5% to reach 1.6m tonnes in
1996. We believe that it will grow at an average rate of 7.4% over the next nine
years to reach 2.9m tonnes by 2005.
 
    The previously state-owned National Steel Corp. is currently the only
producer of hot-rolled coil, and like Sahaviriya Steel in Thailand, relies on
imported slab from a variety of sources for feed. This rolling mill has plans to
remove some bottlenecks and expand capacity by 500,000 tpy. The Jacinto Group is
planning to build a Danieli-designed thin slab hot-strip mini-mill with a
capacity of 1.25m tpy. There are several projects planned to install cold
rolling and galvanising facilities. The additions to cold rolling capacity from
announced projects are insufficient to meet the projected growth in demand and
it will remain a net importer of cold-rolled coil unless further projects are
announced.
 
KOREA
 
    The Korean steel industry dominates the region. Korea is a major player in
the global steel market. It produced 39m tonnes of steel in 1996, of which
Posco, the second largest steel producing company in the world, produced over
24m tonnes, 19.5m tonnes of which was hot-rolled coil. Posco is one of the
lowest cost producers of hot strip in the western world. Total imports of steel
products into Korea in 1996 were 11.1m tonnes. This comprised 4.2m tonnes of
semi finished goods and 6.87m tonnes of finished goods. Total exports of steel
products were 9.89m tonnes. This comprised 0.44m tonnes of semi finished goods
and 9.45m tonnes of finished goods. Overall, net imports of semi finished and
finished goods into Korea in 1996 were 1.65m tonnes.
 
    Korean steel consumption will continue to grow strongly at about 6% per year
on average over the next nine years. There are a large number of sheet steel
projects planned to come on stream over the next five years, though some, such
as Hanbo Steel whose problems have been well-publicised, may take longer to be
realised.
 
TAIWAN
 
    Strong industrial growth in Taiwan has supported sheet growth. The Taiwanese
sheet steel market was just over 7m tonnes in 1996 and is expected to grow by an
average of almost 8% per year over the forecast period. Remarkably, Taiwan has a
large but mainly balanced trade in sheet products. In 1996, it exported 2.6m
tonnes of sheet, 68% of which was hot-rolled coil, and it imported 2.5m tonnes
of sheet, of which more than 50% was cold-rolled.

- --------------------------------------------------------------------------------
 
                              RESOURCE STRATEGIES
 
    Total imports of steel products into Taiwan in 1996 were 10.1m tonnes. This
comprised 5.95m tonnes of semi finished goods and 4.1m tonnes of finished goods.
Total exports of steel products were 3.32m tonnes. This comprised 0.02m tonnes
of semi finished goods and 3.3m tonnes of finished goods. Overall, net imports
of semi finished and finished goods into Taiwan in 1996 were 6.78m tonnes.
 
    Hot-rolled output from China Steel Corporation's new hot mill is expanding
rapidly, and Yieh Loong has started production on its new 2.4m tpy hot rolling
mill. Given the predicted growth in demand, the country is likely to be a net
importer of cold-rolled and coated sheet unless further projects are planned.
 
OTHER ASEAN MARKETS
 
    There are likely to be export opportunities for new Asean producers to
supply the emerging markets for steel in the smaller less developed countries
such as Vietnam, Cambodia, Laos and Burma. These markets are currently consuming
only very small quantities of steel, and most of this is reinforcing bar for
construction. In the longer term, however, these markets will grow and imports
will meet this demand until sufficient demand will support domestic facilities.
China is also expected to remain an importer, particularly of higher value added
sheet products such as high strength low alloy and other specialty grades of
steels.

SUMMARY
 
- -  Regional steel consumption growth, which had been robust up to mid-1997, is
   set to moderate this year and in 1998 in response to the economic uncertainty
   and lower economic activity. Nevertheless, the growth prospects for the
   region remain considerably higher than other steel consuming areas of the
 
                                      C-11

                              RESOURCE STRATEGIES
 
   world. With the obvious exceptions of Korea and Taiwan, the region has been a
   significant net importer of sheet products and is expected to remain so.
 
- -  Long term outlook for steel consumption in the region is good. As economies
   of the region develop, consumption of flat products is expected to grow at a
   faster rate than long products, because demand for automotives, appliances
   and other products made with flat steel will grow with the increasing
   prosperity of the population.
 
- -  All of the ASEAN countries state that they are now committed to trade
   liberalisation and, as members of Afta, have committed to reducing tariffs on
   all steel products to 5% by the year 2003. Therefore, new producers locating
   in these markets will be competing in the global steel market and must be
   efficient on an international basis.
 
- -  Currency markets are expected to stabilise, albeit at lower levels, in
   mid-1998. We expect there to be a general recovery in demand in 1999 and over
   the remainder of the forecast period growth should be steady.
 
- -  In several countries, stock market volatility has been exacerbated by the
   currency problems and this has made it more difficult to raise funds to
   finance capital projects. Several planned new production facilities are
   likely to be delayed and some may be suspended indefinitely because of the
   recent turmoil. For this reason, imports are likely to continue to play a
   significant role for the foreseeable future.
 
- -  Forecast sheet steel prices (shown in the accompanying chart) are likely to
   level out in nominal dollar terms in the region. These price levels represent
   spot transaction prices for commercial grades; there are substantial premiums
   on top of these base prices for higher value-added sheet products supplied to
   individual customer requirements. As long as currencies continue to devalue,
   the rising cost of steel imports will have a dampening effect on steel
   demand.

                              RESOURCE STRATEGIES
 
SOME OF THE COMPETITIVE ADVANTAGES OF NSM
 
- -  Thailand is a significant importer of sheet products and therefore there are
   significant opportunities for import substitution.
 
- -  NSM has several advantages over the incumbent hot-rolled producer, Sahaviriya
   Steel Industries, because it can be more flexible in response to customers'
   requirements in terms of dimensions, grades, quality and just-in-time
   delivery. NSM will face more formidable competition from the other new player
   in the hot rolling market, the Japanese joint venture Siam Strip Mill when it
   comes on stream in late 1998 or early 1999. However, NSM will have almost a
   year to establish customer relationships with Thai consumers who currently
   must rely on imports. Given our forecasts of sheet consumption, we believe
   that there will be room for both players to supply primarily the Thai market
   in the medium term.
 
- -  NSM will produce a full range of steel grades including HSLA grades for the
   automotive industry and API grades for the higher quality end of the pipe
   industry. Therefore, it should be able to compete at the top end of the
   hot-rolled coil market with strip sourced from Korea and Taiwan, leaving the
   Sahaviriya mill to serve the commercial quality commodity end of the market.
 
- -  The ability to produce a broad range of qualities to tight specifications at
   low cost means that the mill output is potentially attractive for export
   markets worldwide. NSM has the support of two of the world's biggest global
   steel traders who are willing to offtake significant volumes of higher grade
   material.
 
- -  The ability to carry out ferritic rolling on the hot strip mill allows the
   unique configuration of the finishing plant, combining a two stand cold
   rolling mill with an inline galvanising line. This combination facility,
   which will primarily produce hot-dipped galvanised sheet, will also be able
   to produce a cold-rolled equivalent coil and pickled and oiled. The principal
   advantage of this type of facility is its flexibility and low production
   costs.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The Certificate of Incorporation of NSM Steel (Delaware), Inc. provides that
directors of NSM Steel (Delaware), Inc. shall, to the full extent not prohibited
by the General Corporation Law of the State of Delaware (the "DGCL"), not be
liable to NSM Steel (Delaware), Inc. or its stockholders for monetary damages
for breach of such director's fiduciary duty as a director.
 
    Section 145 of the DGCL provides that a corporation may indemnify directors
and officers as well as other employees and individuals against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with specified actions, suits or proceedings, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation, a "derivative action") if they acted in good faith and
in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, if they had not reasonable cause to believe their conduct was
unlawful. A similar standard is applicable in the case of derivative actions,
except that indemnification only extends to expenses (including attorneys' fees)
incurred in connection with the defense or settlement of such actions, and the
statute requires court approval before there can be any indemnification where
the person seeking indemnification has been found liable to the corporation. The
statute provides that it is not exclusive of other indemnification that may be
granted by a corporation's bylaws, disinterested director vote, stockholder
vote, agreement or otherwise.
 
    Neither the Articles of Association (By-laws) of Nakornthai Strip Mill
Public Company Limited (the "Company") nor the Public Limited Company Act (the
"PLCA") specifically provide for an indemnification of directors and officers of
the Company. However, the PLCA excludes a director from being held liable to the
Company, any shareholder or the Company's creditor, if her act has been approved
or ratified by the shareholders' resolution, even if it has been rescinded
later. A director may be exempt from liabilities for an alleged breach in
certain situations, e.g., she can prove that she took no part in the alleged
breach, or that she made an objection in the meeting, or that she has taken
reasonable actions or precautions to avoid such a breach.

ITEM 22.  UNDERTAKINGS
 
    Each of the undersigned Registrants hereby undertakes that 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.
 
    Each of the undersigned Registrants hereby undertakes (i) 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, and (ii) to arrange or provide for a
facility in the U.S. for the purpose of responding to such requests.
 
                                      II-4

    Each of the undersigned Registrants 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.
 
    Each of the undersigned Registrants hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
undersigned undertake that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed to be underwriters, in addition to the
information called for by the other items of the applicable form.
 
    Each of the undersigned Registrants hereby undertakes that every prospectus:
(i) that is filed pursuant to the immediately preceding paragraph or (ii) that
purports to meet the requirements of Section 10(a)(3) of the Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes 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.
 
    Each of the undersigned Registrants 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, (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement; (2) that, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof; (3) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering; and (4) if the registrant is a
foreign private issuer, to file a post-effective amendment to the registration
statement to include any financial statements required by Section210.3-19 of
this chapter at the start of any delayed offering or throughout a continuous
offering.
 
    Each of the undersigned Registrants undertakes that (1) for purposes of
determining liability under the Securities Act of 1933, the information omitted
from the form of prospectus filed as part of this registration statement in
reliance upon Rule 430A and contained in a form of prospectus filed by such
Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this registration statement as of the time it was
declared effective and (2) for the purpose of determining any liability under
the Securities Act of 1933, each post-effective amendment that contains a form
of prospectus 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.
