    This Solicitation/Recommendation Statement on Schedule 14D-9 (this "SCHEDULE
14D-9") relates to an offer by Co-Steel Merger Corporation, a Delaware
corporation (the "PURCHASER"), an indirect wholly-owned subsidiary of Co-Steel
Inc., a Canadian corporation ("CO-STEEL"), to purchase all of the Shares (as
defined below) of New Jersey Steel Corporation, a Delaware corporation (the
"COMPANY" or "NJ STEEL").
 
ITEM 1. SECURITY AND SUBJECT COMPANY.
 
    The name of the subject company is New Jersey Steel Corporation. The address
of its principal executive office is North Crossman Road, Sayreville, New Jersey
08872. The title of the class of equity securities to which this Schedule 14D-9
relates is the Common Stock, par value $.01 per share, of the Company (the
"SHARES").
 
ITEM 2. TENDER OFFER OF THE BIDDER.
 
    This Schedule 14D-9 relates to the tender offer (the "OFFER") disclosed in
the Schedule 14D-1 dated November 28, 1997 (as amended or supplemented, the
"SCHEDULE 14D-1") filed with the Securities and Exchange Commission (the
"COMMISSION") by Purchaser, Co-Steel USA Holdings, Inc. and Co-Steel, relating
to an offer by the Purchaser to purchase all outstanding Shares at a price of
$23.00 per Share, net to the seller in cash, without interest (the "OFFER
PRICE"), upon the terms and subject to the conditions set forth therein. The
principal executive offices of Co-Steel are located at Scotia Plaza, 40 King
Street West, PO Box 130, Toronto, Ontario, Canada M5H 3Y2. The registered
offices of Purchaser and Holdings is 1013 Centre Road, Wilmington, Delaware.
 
ITEM 3. IDENTITY AND BACKGROUND.
 
    (A) IDENTITY  The name and business address of the Company, which is the
person filing this Schedule 14D-9, are set forth in Item 1 above. Unless the
context otherwise requires, references to the Company in this Schedule 14D-9 are
to the Company and its subsidiary, viewed as a single entity.
 
    (B) CONTRACTS, AGREEMENTS, ETC.
 
GENERAL
 
    The Offer is being made pursuant to a Tender Offer Agreement and Agreement
and Plan of Merger dated as of November 21, 1997 (the "TENDER AGREEMENT") among
the Company, the Company's majority stockholder Von Roll Holding AG ("VON
ROLL"), Purchaser and Co-Steel. A copy of the Tender Agreement is filed as
EXHIBIT A to this Schedule 14D-9 and is hereby incorporated by reference. The
Tender Agreement provides that, among other things, as soon as practicable after
the purchase of Shares pursuant to the Offer and the satisfaction of the other
conditions set forth in the Tender Agreement and in accordance with the relevant
provisions of the General Corporation Law of the State of Delaware ("DELAWARE
LAW" or the "DGCL"), Purchaser will be merged with the Company (the "MERGER").
Following consummation of the Merger, the Company will continue as the surviving
Company (the "SURVIVING COMPANY"). At the effective time of the Merger (the
"Effective Time"), each Share issued and outstanding immediately prior to the
Effective Time (other than Shares held by the Company or by any subsidiary of
the Company, or owned by the Purchaser or Shares held by stockholders who shall
have demanded and perfected appraisal rights, if any, under Delaware Law) will
be canceled and converted automatically into the right to receive the price per
Share paid pursuant to the Offer in cash, without interest (the "MERGER
CONSIDERATION"). The Tender Agreement is summarized in Item 3 of this Schedule
14D-9. Pursuant to a Stockholder Agreement dated November 21, 1997 between
Co-Steel and Von Roll (the "STOCKHOLDER AGREEMENT"), Von Roll has agreed to
tender the 3,561,500 shares of the Company owned by it in the Offer. The
Stockholder Agreement also provides that in the event the Offer is not completed
for any reason other than a failure of the Conditions to the Offer (other than
the condition prohibiting a change of
 
                                       2
<PAGE>
recommendation by the Board of Directors of NJ Steel (the "NJ STEEL BOARD"), see
"The Tender Agreement--Conditions to the Offer" below), Co-Steel will purchase
the Shares owned by Von Roll for $23.00 per share. A copy of the Stockholder
Agreement is annexed hereto as EXHIBIT B.
 
INDEMNIFICATION AGREEMENTS
 
    The Restated Certificate of Incorporation of the Company, as amended to date
(the "CERTIFICATE OF INCORPORATION"), provides that the Company shall indemnify
its officers and directors to the fullest extent permitted by Delaware Law, and
that no director of the Company shall be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director.
The Certificate of Incorporation of the Company has been filed as EXHIBIT C to
this Schedule 14D-9 and is hereby incorporated by reference. Article VI of the
By-Laws of the Company also provides for indemnification of officers and
directors of the Company. Article VI of the By-Laws of the Company has been
filed as EXHIBIT D to this Schedule 14D-9 and is hereby incorporated by
reference.
 
    See "The Tender Agreement--Indemnification" below for information with
respect to the Purchaser's agreement to continue the existing indemnification
arrangements with officers and directors of the Company for a period of 6 years.
 
PURCHASE OF OPTIONS
 
    The Tender Agreement provides that at the time of the Merger, all
outstanding options under the Company's Incentive Stock Option Plan and 1996
Stock Option Plan, whether or not currently exercisable, will be purchased by
Co-Steel for a purchase price equal to the difference between the Offer Price of
$23.00 per share and the exercise price of such options. Options under the two
plans are held by two individuals--Mr. Gary Giovannetti, the President and Chief
Executive Officer, holds options covering 115,000 shares at an exercise price of
$5.00 per share, and a mill superintendent holds options covering 12,500 shares
at and exercise price of $11.75 per share.
 
THE TENDER AGREEMENT
 
    VOTE REQUIRED TO APPROVE MERGER.  The DGCL requires that the plan of merger
must be approved by the NJ Steel Board and, if the "short form" merger procedure
described below is not available, by the holders of a majority of the Company's
Common Stock. The NJ Steel Board approved the Offer, the Merger and the Tender
Agreement at its November 20, 1997 meeting and the only additional action of the
Company that may be necessary is approval by the holders of Common Stock if the
"short-form" merger procedure described below is not available. Under the DGCL,
the affirmative vote of holders of a majority of the outstanding Common Stock
(including any Common Stock owned by the Purchaser) is generally required to
approve a Merger. As Co-Steel and/or Purchaser will acquire a majority of the
outstanding Common Stock, through Von Roll's participation in the Offer or
otherwise through purchasing the 3,561,500 Common Stock owned by Von Roll
pursuant to the Stockholder Agreement, Co-Steel will have sufficient voting
power to effect the Merger without the vote of any other stockholder of the
Company. However, the DGCL also provides that if a corporation owns at least 90%
of each class of stock of a subsidiary, it can effect a "short-form" merger with
that subsidiary without the action of the subsidiary's other stockholders.
Accordingly, if, as a result of the Offer or otherwise, Co-Steel and/or
Purchaser acquires or controls the voting power of at least 90% of the
outstanding Common Stock, they could (and, under the Tender Agreement, are
required to) effect the Merger using the "short-form" merger procedures without
prior notice to, or any action by, any other stockholder of the Company.
 
    CONDITIONS TO THE MERGER.  The Tender Agreement provides that the Merger is
subject to the satisfaction of certain conditions, including the following: (1)
if required by applicable law, the Tender Agreement having been approved and
adopted by the affirmative vote of holders of a majority of the outstanding
Common Stock, (2) no statute, rule, regulation, executive order, decree,
temporary restraining
 
                                       3
<PAGE>
order, preliminary or permanent injunction or other order issued by any court of
competent jurisdiction or other Federal, state or local government or any court,
administrative agency or commission or other governmental authority or agency,
domestic or foreign (a "GOVERNMENTAL ENTITY"), or other legal restraint or
prohibition preventing the consummation of the Merger being in effect; provided,
however, that each of the parties shall have used reasonable efforts to prevent
the entry of any such injunction or other order and to appeal as promptly as
possible any injunction or other order that may be entered and (3) the Purchaser
shall have previously accepted for payment and paid for the Common Stock
pursuant to the Offer.
 
    TERMINATION OF THE TENDER AGREEMENT.  The Tender Agreement may be terminated
at any time prior to the Effective Time, whether before or after approval by the
stockholders of the Company (provided, however, that if Common Stock is
purchased pursuant to the Offer, neither Co-Steel nor Purchaser may terminate
the Tender Agreement), (1) by mutual written consent of Purchaser and the
Company, (2) by either Purchaser or the Company (a) if the Purchaser has not
accepted for payment any Common Stock pursuant to the Offer prior to May 5,
1998, PROVIDED, HOWEVER, that the right to terminate the Tender Agreement
pursuant to this sentence will not be available to (i) Purchaser, if Purchaser
has breached its obligations under the Tender Agreement or (ii) any party whose
failure to perform any of its obligations under the Tender Agreement results in
the failure of any such condition or if the failure of such condition results
from facts or circumstances that constitute a willful breach of a representation
or warranty under the Tender Agreement by such party, or (b) if any Governmental
Entity shall have issued an order, decree or ruling or taken any other action
permanently enjoining, restraining or otherwise prohibiting the acceptance for
payment of, or payment for, Common Stock pursuant to the Offer or the Merger and
such order, decree or ruling or other action has become final and nonappealable,
(3) by Purchaser prior to the purchase of Common Stock pursuant to the Offer in
the event of a breach or failure to perform by the Company of any
representation, warranty, covenant or other agreement contained in the Tender
Agreement which (i) would give rise to the failure of a condition set forth in
paragraph (e) or (f) under "Certain Conditions of the Offer" and (ii ) cannot be
or has not been cured within 30 days after the giving of written notice to the
Company, (4) by Co-Steel or the Purchaser if either Co-Steel or the Purchaser is
entitled to terminate the Offer as a result of the occurrence of any event set
forth in paragraph (d) under "Certain Conditions of the Offer," (5) by the
Company in accordance with the terms of the Tender Agreement described below in
"Takeover Proposals," provided that it has complied with all provisions thereof,
including the notice provisions therein, and that it complies with applicable
requirements relating to the payment (including the timing of any payment) of
the Termination Fee (as defined below) as provided in the terms of the Tender
Agreement described below in "Fees and Expenses" (it being understood that as
provided in the terms of the Tender Agreement described below in the second
paragraph of "Takeover Proposals" the Company will be required to terminate the
Tender Agreement) or (6) by the Company in the event of a material breach or
failure to perform in any material respect by Co-Steel or the Purchaser of any
representation, warranty, covenant or other agreement contained in the Tender
Agreement which cannot be or has not been cured within 30 days after the giving
of written notice to Co-Steel and the Purchaser.
 
    TAKEOVER PROPOSALS.  The Tender Agreement provides that the Company will
not, nor will it permit any of its subsidiaries to, nor will it authorize or
permit any of its officers, directors or employees or any investment banker,
financial advisor, attorney, accountant or other representative retained by it
or any subsidiary to, director or indirectly, (1) solicit, initiate or knowingly
encourage the submission of any Takeover Proposal (as defined below) or (2)
participate in any discussions or negotiations regarding, or furnish to any
person any nonpublic information with respect to, or take any other action
designed or reasonably likely to facilitate any inquiries or the making of any
proposal that constitutes any Takeover Proposal; provided, however, that if, at
any time prior to the acceptance for payment of Common Stock pursuant to the
Offer, the NJ Steel Board determines in good faith, after consultation with
outside counsel, that it is reasonably advisable to do so in order to comply
with its fiduciary duties to the Company's stockholders under applicable law,
the Company may, in response to a Takeover Proposal which was not solicited
subsequent to the date of the Tender Agreement, and subject to compliance with
the notification
 
                                       4
<PAGE>
provisions discussed below, (a) furnish information with respect to the Company
to any person pursuant to a customary confidentiality agreement and (b)
participate in discussions and negotiations regarding such Takeover Proposal.
The Tender Agreement provides that any violation of the restrictions set forth
in the preceding sentence by any director, officer or employee of the Company or
any of its subsidiaries or any investment banker, financial advisor, attorney,
accountant or other representative or agent of the Company or any of its
subsidiaries will be deemed to be a breach of the Company's obligations under
the Tender Agreement. The Tender Agreement defines "TAKEOVER PROPOSAL" as any
inquiry, proposal or offer from any person relating to any direct or indirect
acquisition or purchase of a substantial amount of assets of the Company and its
subsidiaries, taken as a whole (other than the purchase of the Company's
products in the ordinary course of business), or more than a 40% interest in the
total voting securities of the Company or any of its subsidiaries or any tender
offer or exchange offer that if consummated would result in any person
beneficially owning 40% or more of any class of equity securities of the Company
or any of its subsidiaries or any merger, consolidation, business combination,
sale of substantially all the assets, recapitalization, liquidation, dissolution
or similar transaction involving the Company or any of its subsidiaries, other
than the transactions contemplated by the Tender Agreement.
 
    The Tender Agreement provides further that unless the NJ Steel Board has
terminated the Tender Agreement as described above, neither the NJ Steel Board
nor any committee thereof may (1) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Co-Steel, the approval or recommendation by such
Board of Directors or such committee of the Offer, the Merger or the Tender
Agreement, (2) approve or recommend, or propose publicly to approve or
recommend, any Takeover Proposal or (3) cause the Company to enter into any
letter of intent, agreement in principle, acquisition agreement or other similar
agreement (each, an "Acquisition Agreement") related to any Takeover Proposal.
Notwithstanding the foregoing, in the event that prior to the acceptance for
payment of Common Stock pursuant to the Offer the NJ Steel Board determines in
good faith, after consultation with outside counsel, that it is reasonably
advisable to do so in order to comply with its fiduciary duties to the Company's
stockholders under applicable law, the NJ Steel Board may, in response to an
unsolicited Superior Proposal (as defined below) (subject to the following
proviso), (a) withdraw or modify its approval or recommendation of the Offer,
the Merger or the Tender Agreement or (b) approve or recommend any such Superior
Proposal if concurrently with such approval or recommendation the Company
terminates the Tender Agreement and enters into an Acquisition Agreement with
respect to a Superior Proposal; provided, that in the case of this clause (b),
only at a time that is after the later of (i) the third business day following
Co-Steel's receipt of written notice advising Co-Steel that the NJ Steel Board
has received a Superior Proposal, specifying the material terms of such Superior
Proposal and identifying the person making such Superior Proposal and (ii) in
the event of an amendment to the price or any material term of a Superior
Proposal, one business day following Co-Steel's receipt of written notice
containing the material terms of such amendment, including any change in price
(it being understood that each further amendment to the price or any material
terms of a Superior Proposal will necessitate an additional written notice to
Co-Steel and an additional one business day period prior to which the Company
can take the actions set forth in clause (b) above). The Tender Agreement
defines a "Superior Proposal" as any bona fide Takeover Proposal made by a third
party (1) that is on terms which the NJ Steel Board determines in its good faith
judgment (based on consultation with the Company's financial advisor) to be more
favorable to the Company's stockholders than the Offer and the Merger and (2)
for which financing, to the extent required, is then committed or which, in the
good faith judgment of the NJ Steel Board, is capable of being obtained by such
third party.
 
    In addition to the obligations of the Company set forth in the preceding
paragraphs, the Tender Agreement provides that the Company must promptly advise
Co-Steel orally and in writing of any request for nonpublic information (except
in the ordinary course of business and not in connection with a possible
Takeover Proposal) or of any Takeover Proposal known to it, the material terms
and conditions of such request or Takeover Proposal and the identify of the
person making such request or Takeover Proposal.
 
                                       5
<PAGE>
The Company must promptly inform Co-Steel of any material change in the details
(including amendments or proposed amendments) of any such request or Takeover
Proposal.
 
    The Tender Agreement provides that nothing contained therein will prohibit
the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14d-9 or Rule 14e-(a) promulgated under the Exchange Act or
from making any disclosure to the Company's stockholders if, in the good faith
judgment of the NJ Steel Board, after consultation with outside counsel, failure
to so disclose would be inconsistent with applicable law; provided, however,
that neither the Company nor its Board of Directors nor any committee thereof
may, except as permitted by the Tender Agreement, withdraw or modify, or propose
to withdraw or modify, its position with respect to the Offer, the Merger or the
Tender Agreement or approve or recommend, or propose to approve or recommend, a
Takeover Proposal.
 
    FEES AND EXPENSES.  The Tender Agreement provides that except as provided
below, all fees and expenses incurred in connection with the Offer, the Merger,
the Tender Agreement and the transactions contemplated by the Tender Agreement
will be paid by the party incurring such fees or expenses, whether or not the
Offer or the Merger is consummated. The Tender Agreement further provides that
the Company will pay, or cause to be paid, in same day funds to Co-Steel the
amount of Five Million ($5,000,000) Dollars (the "Termination Fee") under the
circumstances and at the times set forth as follows: (1) if the Company
terminates the Tender Agreement in accordance with the provisions described
above in clause 5 of "Termination of the Tender Agreement," the Company must pay
50% of the Termination Fee simultaneously with such termination, and 50% of the
Termination Fee upon consummation of the transactions contemplated by the
Superior Proposal giving rise to the Company's right to terminate the Tender
Agreement in accordance with the provisions described above in clause 5 of
"Termination of the Tender Agreement," or upon the earlier consummation of
another Company Acquisition (as defined below); provided that such other Company
Acquisition is consummated within twelve months following termination of the
Tender Agreement, (2) if Co-Steel or the Purchaser terminates the Tender
Agreement in accordance with the provisions described above in clause 4 of
"Termination of the Tender Agreement" and in addition, if within twelve months
after such termination the Company enters into an Acquisition Agreement
providing for a Company Acquisition or the Company recommends to its
stockholders that they accept a Company Acquisition of the type referred to in
clause 3 of the definition of Company Acquisition described below, the Company
must pay (a) 50% of the Termination Fee simultaneously with the entering into of
such Acquisition Agreement or making of such recommendation and (b) 50% of the
Termination Fee upon consummation of the Company Acquisition which was the
subject of such Acquisition Agreement or recommendation, or upon the
consummation, prior to the expiration of such twelve month period, of any other
Company Acquisition (it being understood that if any Company Acquisition is
consummated within such twelve month period and the Company shall not have paid
any amount pursuant to clause (a) above, that upon consummation of such Company
Acquisition the Company must pay 100% of the Termination Fee) and (3) if, at the
time of any termination of the Tender Agreement in accordance with the
provisions described above in clause 2(a) of "Termination of the Tender
Agreement" (as a result of a failure to obtain the Minimum Condition) or in
accordance with the provisions described above in clause 3 of "Termination of
the Tender Agreement," any person shall have publicly announced a proposal to
effect a Company Acquisition and if, within twelve months after such
termination, the Company shall enter into an Acquisition Agreement providing for
a Company Acquisition or the Company shall recommend to its stockholders that
they accept a Company Acquisition of the type referred to in clause 3 of the
definition of Company Acquisition described below, the Company must pay (a) 50%
of the Termination Fee simultaneously with the entering into of such Acquisition
Agreement or making of such recommendation and (b) 50% of the Termination Fee
upon consummation of the Company Acquisition which was the subject of such
Acquisition Agreement or recommendation, or upon the consummation, prior to the
expiration of such twelve month period, of any other Company Acquisition (it
being understood that if any Company Acquisition is consummated within such
twelve month period and the Company shall not have paid any amount pursuant to
clause (a) above, that upon consummation of such
 
                                       6
<PAGE>
Company Acquisition the Company must pay 100% of the Termination Fee). The
Tender Agreement defines a "Company Acquisition" as any of the following
transactions: (1) a merger, consolidation, business combination or a
recapitalization pursuant to which the stockholders of the Company immediately
preceding such transaction hold less than 60% of the equity interests in the
surviving or resulting entity of such transaction (other than the transactions
contemplated by the Tender Agreement); (2) a sale by the Company of assets
(excluding the sale of the Company's products in the ordinary course of
business) representing in excess of 40% of the fair market value of the Company
immediately prior to such sale or the issuance by the Company to any person or
group of Common Stock representing in excess of 40% of the then outstanding
Common Stock of capital stock of the Company (other than in connection with an
underwritten public offering); or (3) the acquisition by any person or group, by
way of a tender offer, exchange offer, or by way of open market purchases, of
beneficial ownership of 40% or more of the then outstanding Common Stock of
capital stock of the Company.
 
    CONDUCT OF BUSINESS BY THE COMPANY.  The Tender Agreement provides that
until the earlier of termination of the Tender Agreement and consummation of the
Offer, the Company will, and will cause its subsidiaries to, carry on their
respective business in the ordinary course consistent with the manner conducted
prior to the execution of the Tender Agreement and, to the extent consistent
therewith, use commercially reasonable efforts to preserve intact their current
business organization, keep available the services of their current officers and
employees and preserve their relationships with customers, suppliers, and others
having business dealings with them. Without limiting the generality of the
foregoing, during the period from the date of the Tender Agreement until the
earlier termination of the Tender Agreement and consummation of the Offer,
except as otherwise contemplated by the Tender Agreement (or for certain matters
disclosed in connection therewith), the Company will not, and will not permit
any of its subsidiaries to, without Co-Steel's prior written consent (which will
not be unreasonably withheld):
 
    (a) (1) increase the compensation payable to or to become payable to any
director, officer or employee (other than increases to employees, other than
officers, made in the ordinary course of business and consistent with past
practice); (ii) grant any severance or termination of pay (other than pursuant
to the normal severance policy of the Company as in effect on the date of the
Tender Agreement) to, or enter into any employment or severance agreement with,
any director, officer or employee; (iii) establish, adopt, enter into or amend
any employee benefit plan or arrangement except as may be required by applicable
law; or (iv) lend or contribute any funds to any director, officer, employee,
affiliate or associate of the Company;
 
    (b) declare or pay any dividend on, or make any other distribution in
respect of, outstanding shares of capital stock;
 
    (c) (i) redeem, purchase or otherwise acquire any shares of its or any
securities or obligations convertible into or exchangeable for any shares of its
capital stock, or any options, warrants or conversion or other rights to acquire
any shares of its capital stock or any such securities or obligations; (ii)

reclassify any of its capital stock or issue or authorize or propose the
issuance of any other securities in respect of, in lieu of or in substitution
for, shares of its capital stock;
 
    (d) (i) issue, deliver, award, grant or sell, or authorize or propose the
issuance, delivery, award, grant or sale (including the grant of any security
interest, liens, claims, pledges, limitations in voting rights, charges or other
encumbrances) of, any shares of any class of its capital stock (including shares
held in treasury), any securities convertible into or exercisable or
exchangeable for any such shares, or any rights, warrants or options to acquire,
any such shares, other than the issuance of shares pursuant to the exercise of
Stock Options granted prior to the date hereof; or (ii) amend or otherwise
modify the terms of any such rights, warrants or options the effect of which
shall be to make such terms more favorable to the holders thereof; (provided
however, the Company may take action to accelerate the vesting of outstanding
stock options);

Act. Prior to replacing all or part of the Board, Purchaser will be required to
mail to the Company's stockholders an Information Statement containing the
information required by Section 14(f) of the Exchange Act and Rule 14f-1

    REASONABLE EFFORTS.  Upon and subject to the terms and subject to the
conditions set forth in the Tender Agreement, Co-Steel, the Purchaser and the
Company have each agreed to use all reasonable efforts to take, or cause to be
taken, all actions, and to do, or cause to be done, and to assist and cooperate
with each other in doing, all things necessary, proper and advisable to
consummate and make effective, in the most expeditious manner practicable, the
Offer, the Merger and the other transactions contemplated by the Tender
Agreement, including using reasonable efforts to take the following actions: (1)
the taking of all reasonable acts necessary to cause the conditions of the Offer
to be satisfied, (2) the obtaining of all necessary actions or nonactions,

all necessary consents, approvals or waivers from third parties, (4) the

customary representations and warranties.
 
    PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR WAIVER.  The Tender
Agreement provides that after the acceptance for payment of Common Stock

is required for the Company to (1) amend or terminate the Tender Agreement, (2)
exercise or waive any of its rights or remedies under the Tender Agreement, (3)
extend the time for performance of Co-Steel and the Purchaser's respective
obligations under the Tender Agreement and (4) take any action to amend or

Offer or the Tender Agreement, the Purchaser will not be required to accept for
payment or, subject to any applicable rules and regulations of the Commission,
including Rule 14e-1(c) under the Exchange Act (relating to Purchaser's

Offer unless (1) the Minimum Condition shall have been satisfied, (2) any
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the regulations thereunder (the "HSR Act") applicable to the
purchase of Common Stock pursuant to the Offer shall have expired or been

Act are satisfied. Furthermore, Purchaser will not be required to accept for
payment or, subject as aforesaid, to pay for any Common Stock not theretofore
accepted for payment or paid for, and may, in accordance with the provisions of
the Tender Agreement described in the

Agreement or amend the Offer with the consent of the Company and Von Roll, if,
upon the scheduled expiration date of the Offer and before the acceptance of
such Common Stock for payment or the payment therefor, any of the following
conditions exist and is continuing and does not result principally from the
breach by Co-Steel or the Purchaser of any of their obligations under the Tender
Agreement:
 
        (a) there shall be instituted or pending by any Governmental Entity any
    suit, action or proceeding (i) challenging the acquisition by Co-Steel or
    the Purchaser of any Common Stock under the Offer, seeking to restrain or
    prohibit the making or consummation of the Offer or the Merger, (ii) seeking

    Common Stock on all matters properly presented to the stockholders of the
    Company or (iv) seeking to prohibit Co-Steel or any of its subsidiaries from
    effectively controlling in any material respect any material portion of the
    business or operations of the Company;
 
        (b) there shall be any statute, rule, regulation, judgment, order or
    injunction enacted, entered, enforced, promulgated or deemed applicable to
    the Offer or the Merger, by any Governmental Entity or court, other than the
    application to the Offer or the Merger of ISRA and any applicable waiting
    periods under the HSR Act, that would result in any of the consequences
    referred to in clauses (i) through (iv) of paragraph (a) above;
 
        (c) there shall have occurred any material adverse change with respect
    to the Company since the date of the Tender Agreement;
 
        (d) the NJ Steel Board or any committee thereof shall have withdrawn or
    modified in a manner adverse to Co-Steel or the Purchaser its approval or

        (e) any of the representations and warranties of the Company set forth
    in the Tender Agreement that are qualified as to materiality shall not be
    true and correct or any such representations and warranties that are not so

    case at the date of the Tender Agreement and at the scheduled or extended
    expiration of the Offer;
 
        (f) the Company shall have failed to perform in any material respect any

        (g) Parent and Sub shall not have received a certificate of the
    President or Chief Financial Officer of the Company dated the expiration
    date of the Offer (i) that the representations and warranties of the Company

    and correct as and at such date, (ii) that the representations and
    warranties that are not so qualified are true and correct in any material
    respect as and at such date, and that (iii) the Company has performed in all
    material respects any material obligation and complied in all material
    respect with any material agreement or material covenant of the Company to
    be performed or complied with by it; or
 
        (h) the Tender Agreement shall have been terminated in accordance with
    its terms;
 
which, in good faith judgment of Co-Steel or the Purchaser, in its sole
discretion, make it inadvisable to proceed with such acceptance of Common Stock
for payment or the payment therefor.
 
                                       10
<PAGE>
    The Tender Agreement provides that (i) the conditions set forth in clause
(e) above shall be deemed not fulfilled only if the respects in which the
representations and warranties made by the Company (without giving effect to any
"materiality" limitations or references to "material adverse effect" set forth
therein) are inaccurate would have a material adverse effect on the Company, and
(ii) if the condition set forth in clause (f) is not fulfilled, Purchaser shall
not be obligated to purchase and pay for any Shares so long as such condition
remains unfulfilled, but Purchaser may not terminate the Offer due solely to
such failure until 30 days after it gives written notice to the Company of such
nonfulfillment and such nonfulfillment is not cured by the end of such 30-day
period.
 
    The Tender Agreement provides that the foregoing conditions are for the sole
benefit of Co-Steel and the Purchaser and (except for the Minimum Condition)
may, subject to the terms of the Tender Agreement, be waived by Co-Steel and the
Purchaser in whole or in part at any time and from time to time in their sole
discretion. The failure by Co-Steel or the Purchaser at any time to exercise any
of the foregoing rights will not be deemed a waiver of any such right, the
waiver of any such right with respect to particular facts and circumstances will
not be deemed a waiver with respect to any other facts and circumstances and
each such right will be deemed an ongoing right that may be asserted at any time
and from time to time.
 
    The foregoing summary of the Tender Agreement is qualified in its entirety
by reference to the Tender Agreement, a copy of which is filed as Exhibit (c)(1)
to this Schedule 14D-9. The Tender Agreement should be read in its entirety for
a more complete description of the matters summarized above.

Stockholder Agreement by means of purchase, dividend, distribution or in any
other way, the "Von Roll Shares").
 
    SALE AND PURCHASE.  The Stockholder Agreement also provides that in the
event the Von Roll shares are not purchased by the Parent pursuant to the Offer
because the Offer is terminated for any reason other than a failure of an Offer
Condition other than condition (d) thereof as described in Section 14, then Von

or otherwise act with Von Roll to effectuate the prompt release of Von Roll from
its guarantee of certain contractual obligations of the Company.

and the subordinated obligations shall take place on the third business day
following satisfaction or waiver of the conditions set forth in the Stockholder
Agreement or such other time as the parties thereto may agree (the "Closing
Date").

representations and warranties of Parent in the Stockholder Agreement shall be
true, correct and complete in all material respects on and as of the Closing
Date; (b) no injunction or order prohibiting the consummation of the
 
                                       11
<PAGE>
transactions contemplated by the Stockholder Agreement shall be outstanding; (c)
all waiting periods under the HSR shall have expired or been terminated; (d) a
satisfactory remediation agreement shall have been entered into with the NJDEP,

of the Company for, any termination, severance or similar fees, (i) the
Management and Technical Services Agreement between them and (ii) the employment
by the Company of any Von Roll employees on an interim basis (including the
Chief Financial Officer); and (f) the closing condition of the Merger Agreement

entirety by reference to the Stockholder Agreement, a copy of which is filed as
EXHIBIT B to this Schedule 14D-9. The Stockholder Agreement should be read in

ITEM 4. THE SOLICITATION OR RECOMMENDATION.
 
    (a) Recommendation of the Board of Directors
 
    The Board has unanimously approved the Offer and the Merger and determined
that the terms of the Offer and the Merger are fair to, and in the best
interests of, the stockholders of the Company and unanimously recommends that
stockholders of the Company accept the Offer and tender their Shares to
Purchaser.
 
    As set forth in the Tender Agreement, the Purchaser will purchase Shares
tendered prior to the close of the Offer if the conditions to the Offer have
been satisfied (or waived).
 
    (b) Background and Reasons for Recommendation
 
    In December, 1993, Von Roll had advised the NJ Steel Board that Von Roll was
interested in selling its approximately 60% ownership of the Company. During
1994, the Company and Von Roll sought a purchaser for the Company and on October
5, 1994, the Company entered into a Plan and Agreement of Merger, and Von Roll
entered into a Stock Purchase Agreement, with International Metals Acquisition
Corp. ("IMAC") pursuant to which IMAC was to acquire all of the Shares at $18.00
per share. IMAC was unable to obtain financing for the transaction and that
agreement was terminated in February, 1995. No effort was made at that time to
find another acquiror because the Company began experiencing operational
problems with its newly-installed melt shop which made a sale at an attractive
price unlikely.
 
    At a meeting of NJ Steel Board held on September 27, 1996, Von Roll
reaffirmed its intention to sell its interest in the Company at such time as the
Company's financial results made it attractive to do so. The NJ Steel Board
authorized interviews of prospective financial advisors to be retained by the
Company to explore in a transaction to realize maximum value for all
stockholders. At a meeting of the NJ Steel Board held on June 17, 1997, the NJ
Steel Board reviewed the candidates for financial advisor. Mr. Robert LeBuhn
agreed to act as a special committee, to make an independent determination as to
the fairness to
 
                                       12
<PAGE>
the stockholders of NJ Steel other than Von Roll (the "MINORITY STOCKHOLDERS")
of any transaction proposed.
 
    At a luncheon meeting in New York City on June 18, 1997, Lew C. Hutchinson,
President and Chief Executive Officer of Co-Steel, advised Georg Hahnloser,
Chairman of the Company and Chief Operating Officer of Von Roll, that Co-Steel
would be interested in exploring the possible purchase of the Company in the
event that a decision were made to sell. Mr. Hutchinson was advised that the
Company intended to retain an investment banker to advise it with respect to
such matters and that Co-Steel's interest would be kept in mind.
 
    By letter dated July 21, 1997, the Company retained the firm of BT
Wolfensohn as its financial advisor to seek a purchaser for all of the stock of
the Company and to advise the NJ Steel Board as to the fairness of the proposed
transaction, from a financial point of view, to the Minority Stockholders.
 
    During July and August, 1997, BT Wolfensohn developed a marketing strategy
and assisted the Company in producing an information memorandum describing the
Company. In August and September, 1997, BT Wolfensohn contacted potential
acquirors. On or about September 9, 1997, Ted Reilly, Vice President and Chief
Financial Officer of Parent, telephoned Alexander Prelat, Interim Chief
Financial Officer of the Company, and advised him of Co-Steel's continued
interest in exploring the possible purchase of the Company. Mr. Prelat referred
Mr. Reilly to Richard Bushnell, Managing Director of BT Wolfensohn, who
generally explained to Mr. Reilly the process that the Company and BT
Wolfensohn, as the Company's financial adviser, intended to follow in seeking a
purchaser for the Company. On September 9, 1997, Mr. Bushnell telefaxed to Lew
Hutchinson, Co-Steel's President and Chief Executive Officer, an executive
summary describing the Company and a form of confidentiality letter, which
Co-Steel executed and returned.
 
    Initially, BT Wolfensohn contacted approximately 37 potential strategic and
financial acquirors to determine their level of interest in acquiring the
Company. As a result of such contacts, approximately 19 potential acquirors
signed confidentiality agreements and received the information memorandum on NJ
Steel. Following the receipt of the information memorandum, BT Wolfensohn sought
non-binding indications of interest from potential buyers specifying preliminary
terms and conditions of an acquisition.
 
    On October 9, 1997, indications of interest were received from 10 potential
buyers. Based on these indications of interest and discussions with these
potential buyers, the Company selected six parties to perform detailed due
diligence on the Company, including management presentations and site visits.
These parties were also provided a form of tender offer and merger agreement for
their review.
 
    On October 29 and 30, 1997, representatives of Co-Steel and its advisers
visited the Company, attended presentations by Company officials, toured its
facilities, received and reviewed copies of additional financial, legal and
other documents concerning the Company and met with various Company officials to
conduct a further due diligence review of the Company. Following such meetings,
representatives of Co-Steel and its advisers were in virtually daily contact
with representatives of the Company and its advisers, as Co-Steel sought to
obtain additional information and clarifications of information previously
provided. On November 14, 1997, final proposals for an acquisition of the
Company were received from five of these six parties with prices ranging from
approximately $14 to $23 per share and with varying terms and conditions.
Co-Steel proposed to acquire NJ Steel pursuant to a merger transaction in which
each outstanding share of Common Stock would be converted into the right to
receive $23.00 in cash and an agreement with Von Roll, pursuant to which
Co-Steel would purchase the Von Roll Shares for $23.00 per share in cash. The
Company determined that Co-Steel submitted the final proposal with the highest
price per share and the most attractive terms and conditions.
 
    On November 17, 1997, BT Wolfensohn advised Co-Steel that it had submitted
the most attractive financial proposal and that the Company and Von Roll were
prepared to negotiate definitive agreements. During the week of November 17,
representatives of NJ Steel and Co-Steel, including legal counsel, had
discussions concerning the transaction and negotiating the terms of the
definitive agreement. At the
 
                                       13
<PAGE>
request of the Company, Co-Steel agreed that the transaction would take the form
of a tender offer, followed by a second step merger.
 
    A special meeting of the NJ Steel Board was held on November 20, 1997, at
which four of the five members of the NJ Steel Board were present. Also present
and participating in the meeting were representatives of BT Wolfensohn and
counsel for NJ Steel. At the meeting, the NJ Steel Board (one member being
absent) reviewed the proposed Tender Agreement in detail with counsel for NJ
Steel. The BT Wolfensohn representatives present at the meeting described their
analytic and valuation processes and rendered their oral opinion, subsequently
confirmed in writing, that the $23.00 per share in cash to be paid in the Offer
was fair from a financial point of view to the Minority Stockholders. The full
text of the written opinion is annexed hereto as EXHIBIT E and is incorporated
herein by reference. NJ Steel stockholders are urged to read the BT Wolfensohn
opinion carefully. Thereafter, the NJ Steel Board reviewed and discussed with BT
Wolfensohn its analytic and valuation processes with a view to understanding the
bases of its analysis and opinion. The NJ Steel Board noted that the Co-Steel
proposal was the best proposal received and appeared very attractive to NJ
Steel's stockholders. Following such reviews and presentations, the NJ Steel
Board voted unanimously (with one director absent) (i) to approve the Tender
Agreement , (ii) to approve the Merger and (iii) to recommend that the
stockholders of NJ Steel accept the Offer and tender their Shares.
 
    On November 21, 1997, NJ Steel and Co-Steel executed the definitive Tender
Offer Agreement and Plan and Agreement of Merger and Von Roll and Co-Steel
simultaneously executed the definitive Stockholder Agreement.
 
    During 1997, one of Co-Steel's subsidiaries purchased steel billets from the
Company at an aggregate purchase price of approximately $1.7 million.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
    The company retained BT Wolfensohn to provide financial advice and
assistance in connection with a possible sale of the Company. Pursuant to a
letter agreement dated July 21, 1997, the Company agreed to pay BT Wolfensohn an
initial fee of $100,000 which will be credited toward payment of any additional
fees, and additional fees to bring BT Wolfensohn's total fees up to 1% of the
transaction value, or approximately $1,680,000. The Company has also agreed to
reimburse BT Wolfensohn for its reasonable out-of-pocket expenses incurred in
connection with rendering its financial advisory services, including reasonable
fees and disbursements of its legal counsel. The Company has agreed to indemnify
BT Wolfensohn (and its control persons, officers, directors, agents and
affiliates) for certain costs, expenses, and liabilities to which it may be
subjected arising out of or related to its engagement as financial advisor.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
    (a) Transactions
 
    To the best knowledge of the Company, neither the Company nor Von Roll, nor
any director, executive officer, affiliate or subsidiary of either of them, has
effected any transaction in the Common Stock of the Company during the past 60
days.
 
    (b) Intent
 
    To the best knowledge of the Company, it is the present intention of all
directors, executive officers and Von Roll to tender all Shares held by them
pursuant to the Offer.
 
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.
 
    See item 3(b).
 
                                       14

ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED.
 
    STOCKHOLDERS CONSIDERING NOT TENDERING THEIR SHARES IN ORDER TO WAIT FOR THE
MERGER SHOULD NOTE THAT IF THE MINIMUM CONDITION IS NOT SATISFIED OR ANY OF THE
OTHER CONDITIONS TO THE OFFER ARE NOT SATISFIED, THE PURCHASER IS NOT OBLIGATED
TO PURCHASE ANY SHARES, AND CAN TERMINATE THE OFFER AND THE TENDER AGREEMENT AND
NOT PROCEED WITH THE MERGER.
 
    Under Delaware Law, the approval of the board of directors and the
affirmative vote of the holders of a majority of the outstanding Shares (unless
at least 90% of the outstanding Shares are held by the Purchaser) are required
to approve the Merger. Accordingly, if the conditions to the Offer are
satisfied, the Purchaser will have sufficient voting power to cause the approval
of the Merger without the affirmative vote of any other stockholder. Under
Delaware Law, if Purchaser acquires, pursuant to the Offer or otherwise, at
least 90% of the then outstanding Shares, Purchaser will be able to approve and
adopt the Tender Agreement and the Merger, without a vote of the Company's
stockholders. Parent, Purchaser and the Company have agreed to use their
reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable to consummate and make effective, in
the most expeditious manner practicable, the Offer, the Merger and the other
transactions contemplated by the Tender Agreement. If Purchaser does not acquire
at least 90% of the then outstanding Shares pursuant to the Offer or otherwise
and a vote of the Company's stockholders is required under Delaware Law, a
longer period of time will be required to effect the Merger.
 
    THE OFFER IS SCHEDULED TO EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
JANUARY 8, 1998, UNLESS THE PURCHASER EXTENDS THE PERIOD OF TIME FOR WHICH THE
OFFER IS OPEN. A copy of the press release issued jointly by the Company and
Parent on November 20, 1997 announcing the Tender Offer and the Merger is filed
as EXHIBIT F to this Schedule 14D-9 and is incorporated herein by reference in
its entirety.

<PAGE>
    AGREEMENT AND PLAN OF MERGER dated as of November 21, 1997 (this
"AGREEMENT") by and among CO-STEEL INC., a Canadian corporation ("PARENT"),
CO-STEEL MERGER CORPORATION, a Delaware corporation and an indirect wholly-owned
subsidiary of Parent ("SUB"), NEW JERSEY STEEL CORPORATION, a Delaware
corporation (the "COMPANY") and VON ROLL HOLDING AG, a Swiss corporation ("VON
ROLL").
 
                                   BACKGROUND
 
    WHEREAS, in furtherance of the acquisition of the Company by Parent on the
terms and subject to the conditions set forth in this Agreement, Parent proposes
to cause Sub to make a tender offer (as it may be amended from time to time as
permitted under this Agreement, the "OFFER") to purchase all the outstanding
shares (collectively, the "SHARES" and individually a "SHARE") of Common Stock,
par value $.01 per share, of the Company (the "COMPANY COMMON STOCK"), at a
purchase price (the "OFFER PRICE") of $23.00 per Share or such higher price as
may be paid in the Offer, net to the seller in cash, without interest, upon the
terms and subject to the conditions set forth in this Agreement; and
 
    WHEREAS, Von Roll, through its Von Roll Steel Holdings AG subsidiary, owns
3,561,500 Shares or approximately 60% of the Shares and, subject to the terms
and conditions hereof, has agreed to tender such Shares in the Offer; and
 
    WHEREAS, the respective Boards of Directors of Parent, Sub and the Company
have approved the Offer and the merger of Sub with the Company (the "MERGER")
upon the terms and subject to the conditions set forth in this Agreement,
whereby each Share, other than Shares owned directly or indirectly by Parent or
the Company and Dissenting Shares (as defined in Section 3.01(d)), will be
converted into the right to receive the Offer Price; and
 
    WHEREAS, Parent, Sub, the Company and Von Roll desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger and also to prescribe various conditions to the Offer and
the Merger.
 
    NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,
Parent, Sub and the Company hereby agree as follows:
 
                                   ARTICLE I
                                   THE OFFER
 
    SECTION 1.01. THE OFFER. (a) Subject to the provisions of this Agreement, as
promptly as practicable but in no event later than five business days after the
date of the public announcement by Parent and the Company of this Agreement, Sub
shall, and Parent shall cause Sub to, commence the Offer. The initial expiration
date for the Offer shall be January 8, 1998. The obligation of Sub to, and of
Parent to cause Sub to, accept for payment, and pay for, any Shares tendered
pursuant to the Offer shall be subject only to the conditions set forth in
Exhibit A (the "OFFER CONDITIONS") (any of which may be waived in whole or in
part by Sub in its sole discretion, provided that, without the consent of the
Company, Sub shall not waive the Minimum Condition (as defined in Exhibit A))
and to the terms and conditions of this Agreement. Sub expressly reserves the
right to modify the terms of the Offer, except that, without the consent of the
Company, Sub shall not (i) reduce the number of Shares subject to the Offer,
(ii) reduce the Offer Price, (iii) amend or add to the Offer Conditions, (iv)
except as provided in the next sentence, extend the Offer, (v) change the form
of consideration payable in the Offer or (vi) amend any other term of the Offer
in any manner adverse to the holders of the Shares, Notwithstanding the
foregoing, Sub may, without the consent of the Company, (A) extend the Offer, if
at the scheduled or extended expiration date of the Offer any of the Offer
Conditions shall not be satisfied or waived, until such time as such conditions
are satisfied or waived, (B) extend the Offer for any period required by any
rule, regulation, interpretation or
 
                                       1
<PAGE>
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer and (C) extend the Offer on one or more
occasions for an aggregate period of not more than 10 business days beyond the
latest expiration date that would otherwise be permitted under clause (A) or (B)
of this sentence, if on such expiration date there shall not have been tendered
at least 90% of the Shares. Parent and Sub agree that if all of the Offer
Conditions are not satisfied on any scheduled expiration date of the Offer then,
provided that all such conditions are reasonably capable of being satisfied, Sub
shall extend the Offer from time to time until such conditions are satisfied or
waived, provided that Sub shall not be required to extend the Offer beyond May
5, 1998. Subject to the terms and conditions of the Offer and this Agreement,
Sub shall, and Parent shall cause Sub to, accept for payment, and pay for, all
Shares validly tendered and not withdrawn pursuant to the Offer that Sub becomes
obligated to accept for payment, and pay for, pursuant to the Offer as promptly
as practicable after the expiration of the Offer.
 
    (b) On the date of commencement of the Offer, Parent and Sub shall file with
the SEC a Tender Offer Statement on Schedule 14D-1 (the "SCHEDULE 14D-1") with
respect to the Offer, which shall contain an offer to purchase and a related
letter of transmittal and summary advertisement, if required, (such Schedule
14D-1 and the documents included therein pursuant to which the Offer will be
made, together with any supplements or amendments thereto, the "Offer
Documents"). Parent and Sub agree that the Offer Documents shall comply as to
form in all material respects with the Securities Exchange Act of 1934, as
amended (the "EXCHANGE ACT"), and the rules and regulations promulgated
thereunder and the Offer Documents, on the date first published, sent or given
to the Company's stockholders, shall not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that no
representation or warranty is made by Parent or Sub with respect to information
supplied by the Company or any of its stockholders specifically for inclusion or
incorporation by reference in the Offer Documents. Each of Parent, Sub and the
Company agree promptly to correct any information provided by it for use in the
Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect, and Parent and Sub further agree to
take all steps necessary to cause the Schedule 14D-1 as so corrected to be filed
with the SEC and the other Offer Documents as so corrected to be disseminated to
the Company's stockholders, in each case as and to the extent required by
applicable federal securities laws. The Company and its counsel shall be given
reasonable opportunity to review and comment upon the Offer Documents prior to
their filing with the SEC or dissemination to the stockholders of the Company.
Parent and Sub agree to provide the Company and its counsel any comments Parent,
Sub or their counsel may receive from the SEC or its staff with respect to the
Offer Documents promptly after the receipt of such comments.
 
    (c) Parent shall provide or cause to be provided to Sub on a timely basis
the funds necessary to accept for payment, and pay for, any Shares that Sub
becomes obligated to accept for payment, and pay for, pursuant to the Offer.
Parent shall (i) provide or cause to be provided to the Company on a timely
basis in connection with the transactions contemplated hereby substitute working

Company's (A) obligations to PNC Bank under that certain Loan and Security
Agreement dated June 6, 1996, if required by said lender, (ii) at or prior to
the Closing, cause (x) all outstanding loans and accrued interest under the
Credit Agreement dated as of June 6, 1996 between the Company and Von Roll to be
paid in full, and (y) the termination of the Subordination and Intercreditor
Agreement date as of June 6, 1996 among Von Roll, the Company and PNC Bank
(formerly Midlantic Bank, National Association) and Von Roll's discharge or
release, in a manner satisfactory to Von Roll, from all obligations thereunder
(the Company's indebtedness under said Loan and Security Agreement and said
Credit Agreement, collectively, the "COMPANY DEBT"); and (iii) shall provide, or
cause the Company to provide Tube City, Inc., at or prior to the Closing, a
substitute guarantee or otherwise to effectuate the release of Von Roll from its
August 21, 1996 guarantee to Tube City, Inc. (the "TUBE CITY GUARANTEE").

    SECTION 1.02. COMPANY ACTIONS. (a) The Company hereby approves of and
consents to the Offer and represents that the Board of Directors of the Company,
at a meeting duly called and held, duly and unanimously adopted resolutions
adopting this Agreement, approving the Offer and the Merger, determining, as of
the date of such resolutions, that the terms of the Offer and the Merger are
fair to, and in the best interests of, the Company's stockholders, recommending
that the Company's stockholders accept the Offer, tender their Shares pursuant
to the Offer and approve this Agreement (if required) and approving the
acquisition of Shares by Sub pursuant to the Offer and the other transactions
contemplated by this Agreement. The Company has been advised by each of its
directors and executive officers that each such person currently intends to
tender all Shares (other than Shares, if any, held by such person that, if
tendered, could cause such person to incur liability under the provisions of
Section 16(b) of the Exchange Act) owned by such person pursuant to the Offer.
 
    (b) On the date the Offer Documents are filed with the SEC, the Company
shall file with the SEC a Solicitation/Recommendation Statement on Schedule
14D-9 with respect to the Offer (such Schedule 14D-9, as supplemented or amended
from time to time, the "SCHEDULE 14D-9") containing, subject to the terms of
this Agreement, the recommendation described in paragraph (a) and shall mail the
Schedule 14D-9 to the stockholders of the Company. The Schedule 14D-9 shall
comply as to form in all material respects with the requirements of the Exchange
Act and the rules and regulations promulgated thereunder and, on the date filed
with the SEC and on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation or warranty is made by
the Company with respect to information supplied by Parent or Sub specifically
for inclusion in the Schedule 14D-9. Each of the Company, Parent and Sub agrees
promptly to correct any information provided by it for use in the Schedule 14D-9
if and to the extent that such information shall have become false or misleading
in any material respect, and the Company further agrees to take all steps
necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule
14D-9 as so amended or supplemented to be filed with the SEC and disseminated to
the Company's stockholders, in each case as and to the extent required by
applicable federal securities laws. Parent and its counsel shall be given
reasonable opportunity to review and comment upon the Schedule 14D-9 prior to
its filing with the SEC or dissemination to stockholders of the Company. The
Company agrees to provide Parent and its counsel any comments the Company or its
counsel may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments.
 
    (c) In connection with the Offer and the Merger, the Company shall cause its
transfer agent to furnish Sub promptly with mailing labels containing the names
and addresses of the record holders of Shares as of a recent date and of those
persons becoming record holders subsequent to such date, together with copies of
all lists of stockholders, security position listings and computer files and all
other information in the Company's possession or control regarding the
beneficial owners of Shares, and shall furnish to Sub such information and
assistance (including updated lists of stockholders, security position listings
and computer files) as Parent may reasonably request in communicating the Offer
to the Company's stockholders. Subject to the requirements of applicable law,
and except for such steps as are necessary to disseminate the Offer Documents
and any other documents necessary to consummate the Merger, Parent and Sub and
their agents shall hold in confidence the information contained in any such
labels, listings and files, will use such information only in connection with
the Offer and the Merger and, if this Agreement shall be terminated, will
deliver, and will use their reasonable efforts to cause their agents to deliver,
to the Company all copies and any extracts or summaries from such information
then in their possession or control.

                                   ARTICLE II
                                   THE MERGER
 
    SECTION 2.01 THE MERGER. Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the Delaware General Corporation
Law (the "DGCL"), at the Effective Time, Sub shall be merged with and into the
Company. As a result of the Merger, the separate corporate existence of Sub
shall cease and the Company shall continue as the surviving corporation (the
"SURVIVING CORPORATION") and shall succeed to and assume all the rights and
obligations of Sub in accordance with the DGCL. At the election of Parent, to
the extent that any such action would not cause a failure of a condition to the
Offer or the Merger, (i) any direct or indirect wholly-owned subsidiary of
Parent may be substituted for and assume all of the rights and obligations of
Sub as a constituent corporation in the Merger or (ii) the Company may be merged
with and into Sub with Sub continuing as the Surviving Corporation with the
effects set forth above and in Section 2.04. In either such event, the parties
agree to execute an appropriate amendment to this Agreement in order to reflect
the foregoing.
 
    SECTION 2.02 CLOSING. The closing of the Merger will take place at 10:00
a.m. (New York City Time) on a date to be specified by Parent or Sub, as soon a
practicable following satisfaction or waiver of the conditions set forth in
Article VIII (the "CLOSING DATE"; which date shall be no later than the tenth
business day following satisfaction or waiver of such conditions), at the
offices of Wilentz Goldman & Spitzer, 90 Woodbridge Center Drive, Woodbridge,
NJ, unless another date, time or place is agreed to in writing by the parties
hereto.
 
    SECTION 2.03 EFFECTIVE TIME. As promptly as practicable after the Closing
Date, the parties hereto shall cause the Merger to be consummated by filing a
certificate of merger or other appropriate documents (in any such case, the
"CERTIFICATE OF MERGER") with the Secretary of State of the State of Delaware,
in such form as required by, and executed in accordance with the relevant
provisions of, the DGCL. The Merger shall become effective at such time as the
Certificate of Merger is duly filed, or at such other time as Sub and the
Company shall agree should be specified in the Certificate of Merger (the time
the Merger becomes effective being hereinafter referred to as the "EFFECTIVE
TIME").
 
    SECTION 2.04 EFFECTS OF THE MERGER. At the Effective Time, the effects of
the Merger shall be as provided in Section 259 of The DGCL.
 
    SECTION 2.05 CERTIFICATE OF INCORPORATION; BY-LAWS.
 
    (a) At the Effective Time, the Certificate of Incorporation of the Company,
as in effect immediately prior to the Effective Time, shall be amended as of the
Effective Time so that Articles FIRST and FOURTH thereof shall read in their
entirety as follows:
 
        "FIRST: The name of the Corporation is:
 
                           Co-Steel Sayreville, Inc."
 
        "FOURTH: The aggregate number of shares of all classes of stock which
    the Corporation shall have authority to issue is 1,000 shares of common
    stock, par value $1.00 per share."
 
and as so amended shall be the Certificate of Incorporation of the Surviving
Corporation.
 
    (b) At the Effective Time, the By-Laws of Sub, as in effect immediately
prior to the Effective Time, shall be the By-Laws of the Surviving Corporation
until thereafter changed or amended, subject to Section 7.02, as provided
therein or by applicable law.
 
    SECTION 2.06 DIRECTORS AND OFFICERS. The directors of Sub immediately prior
to the Effective Time shall be the initial directors of the Surviving
Corporation, and the officers of the Company immediately prior to the Effective
Time shall be the initial officers of the Surviving Corporation, each to
 
                                       4
<PAGE>
hold office in accordance with the Certificate of Incorporation and By-Laws of
the Surviving Corporation and in each case until their respective resignation or
removal or their respective successors are duly elected and qualified, as the
case may be.
 
                                  ARTICLE III
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES
 
SECTION 3.01 CONVERSION OF SECURITIES.
 
    (A) CAPITAL STOCK OF SUB. Each share of capital stock of Sub ("SUB COMMON
STOCK") issued and outstanding immediately prior to the Effective Time shall be
converted into and become one validly issued, fully paid and nonassessable share
of Common Stock, par value $1.00 per share, of the Surviving Corporation.
 
    (B) CANCELLATION OF TREASURY STOCK AND PARENT OWNED STOCK. Each share of
Company Common Stock held in the treasury of the Company and each Share owned by
Parent or any direct or indirect wholly-owned subsidiary of Parent or of the
Company immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof and no consideration shall be
delivered in exchange therefor.
 
    (C) CONVERSION OF COMPANY COMMON STOCK. At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Sub, the Company or the
holders of the Shares, each Share (other than Shares to be canceled in
accordance with Section 3.01(b) and Dissenting Shares) shall be converted into
the right to receive the Offer Price in cash, without interest (the "MERGER
CONSIDERATION").
 
    (D) DISSENTING SHARES. Notwithstanding anything in this Agreement to the
contrary, any issued and outstanding Shares held by a person (a "DISSENTING
STOCKHOLDER") who objects to the Merger and complies with all the provisions of
Delaware law concerning the right of holders of Shares to dissent from the
Merger and require appraisal of their Shares ("DISSENTING SHARES") shall not be
converted as described in Section 3.01(c), but shall be converted into the right
to receive such consideration as may be determined to be due to such Dissenting
Stockholder pursuant to Delaware law. If, after the Effective Time, such
Dissenting Stockholder withdraws his demand for appraisal or fails to perfect or
otherwise loses his right to appraisal, in any case pursuant to the DGCL, his
shares shall be deemed to be converted as of the Effective Time into the right
to receive the Merger Consideration. The Company shall give Parent prompt notice
upon receipt by the Company of any written demands for appraisal rights,
withdrawal of such demands, and any other written communications delivered to
the Company pursuant to Section 262 of the DGCL, and the Company shall give
Parent the opportunity, to the extent permitted by law, to direct all
negotiations and proceedings with respect to such demands. The Company shall not
voluntarily make any payment with respect to any demands for appraisal rights
and shall not, except with the prior written consent of Parent, settle or offer
to settle any such demands.
 
SECTION 3.02 EXCHANGE OF CERTIFICATES.
 
    (A) PAYING AGENT. Prior to the Effective Time, Parent shall designate a bank
or trust company to act as paying agent in the Merger (the "PAYING AGENT"), and,
from time to time on, prior to or after the Effective Time, Parent shall make
available, or cause the Surviving Corporation to make available, to the Paying
Agent cash in amounts and at the times necessary for the prompt payment of the
Merger Consideration upon surrender of certificates representing Shares as part
of the Merger pursuant to Section 3.01 (it being understood that any and all
interest earned on funds made available to the Paying Agent pursuant to this
Agreement shall be turned over to Parent).
 
    (B) EXCHANGE PROCEDURES. As soon as reasonably practicable after the
Effective Time, Parent will instruct the Paying Agent to mail to each holder of
record of a certificate or certificates which
 
                                       5
<PAGE>
immediately prior to the Effective Time evidenced outstanding Shares (other than
Shares held by Parent and Dissenting Shares) (the "CERTIFICATES") (i) a letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for cash. Upon surrender
of a Certificate for cancellation to the Paying Agent together with such letter
of transmittal, duly executed, and such other customary documents as may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive the Merger Consideration in exchange therefor and the
Certificate so surrendered shall forthwith be canceled.
 
    In the event of a transfer of ownership of Shares which is not registered in
the transfer records of the Company, cash may be paid in accordance with this
Article II to a transferee if the Certificate evidencing such Shares is
presented to the Paying Agent, accompanied by all documents required to evidence
and effect such transfer and by evidence that any applicable stock transfer
taxes have been paid. Until surrendered as contemplated by this Section 2.3,
each Certificate shall be deemed at any time after the Effective Time to
evidence only the right to receive the Merger Consideration upon such surrender
in accordance with the terms and conditions set forth herein.
 
    (C) INTEREST. No interest shall be paid on the Merger Consideration.
 
    (D) NO FURTHER RIGHTS IN SHARES. All cash paid upon the surrender for
exchange of certificates evidencing Shares in accordance with the terms and
conditions hereof shall be deemed to have been issued or paid in full
satisfaction of all rights pertaining to such Shares. At the Effective Time, the
stock transfer books of the Company shall be closed and there shall be no
further registration of transfers of Shares thereafter on the records of the
Company. On or after the Effective Time, any valid certificate evidencing Shares
presented to the Paying Agent or Parent for any reason shall evidence only the
right to receive the Merger Consideration in accordance with the terms and
conditions set forth herein.
 
    (E) WITHHOLDING RIGHTS. Parent shall be entitled to deduct and withhold from
the consideration otherwise payable pursuant to this Agreement to any holder of
Shares such amounts as Parent is required to deduct and withhold with respect to
the making of such payment under the Internal Revenue Code of 1986, as amended
(the "CODE"), or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by Parent, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
Shares in respect of which such deduction and withholding were made by Parent.
 
    (F) NO LIABILITY. None of Parent, Sub, the Company or the Paying Agent shall
be liable to any person in respect of any cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. If any
Certificates shall not have been surrendered immediately prior to such date on
which any payment pursuant to this Article III would otherwise escheat to or
become the property of any Governmental Entity (as defined in Section 4.05(b)),
the cash payment in respect of such Certificate shall, to the extent permitted
by applicable law, become the property of the Surviving Corporation, free and
clear of all claims or interests of any person previously entitled thereto.
 
    (G) LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any certificates
evidencing Shares shall have been lost, stolen or destroyed, the Paying Agent
shall pay to such holder the Merger Consideration required pursuant to Section
3.01, in exchange for such lost, stolen or destroyed certificates, upon the
making of an affidavit of that fact by the holder thereof with such assurances
as the Paying Agent, in its discretion and as a condition precedent to the
payment of the Merger Consideration, may reasonably require of the holder of
such lost, stolen or destroyed certificates.

limiting the foregoing, after the Effective Time the Surviving Corporation shall
pay all reasonable out-of-pocket fees and expenses, including reasonable legal
fees, for the Indemnified Parties incurred with respect to the foregoing to the
fullest extent permitted under applicable law promptly after statements therefor
are received by the Surviving Corporation; PROVIDED the person on whose behalf
the expenses are paid provides an undertaking to repay such payments if it is
ultimately determined that such person is not entitled to indemnification.
Parent will cause the Surviving Corporation to maintain for not less than six
years from the Effective Time, directors' and officers' liability insurance
covering the Indemnified Parties who are presently covered by the Company's
directors' and officers' liability insurance or will be so covered
 
                                       21
<PAGE>
at the Effective Time with respect to actions and omissions occurring on or
prior to the Effective Time on terms no less favorable to the Indemnified
Parties than such insurance maintained in effect by the Company on the date
hereof in terms of coverage and amount; PROVIDED, that to the extent such
coverage is not obtainable at less than per annum premiums in the amount of
$175,000 for such insurance, Parent shall cause the Surviving Corporation to
purchase so much coverage as may then be obtained for $175,000 per annum.
 
    (b) This Section 7.02 shall survive the consummation of the Merger at the
Effective Time, is intended to be for the benefit of, and enforceable by, the
Company, Parent, the Surviving Corporation and each Indemnified Party and such
Indemnified Party's heirs and representatives, and shall be binding on all
successors and assigns of Parent and the Surviving Corporation.
 
    (c) Notwithstanding anything to the contrary contained in this Agreement,
from and after the date hereof, the Company may enter into indemnification
agreements, or amended existing indemnification agreements, with current
directors and officers of the Company providing for customary provisions under
Delaware law.
 
    7.03 REASONABLE EFFORTS. The Company and Parent shall each use their
reasonable efforts to (i) take, or cause to be taken, all appropriate action,
and do, or cause to be done, all things necessary, proper or advisable under
applicable law or otherwise to consummate and make effective the transactions
contemplated by this Agreement, (ii) obtain from any Governmental Entities or
third parties any consents, licenses, permits, waivers, approvals,
authorizations or orders required to be obtained or made by Parent or the
Company or any of their Subsidiaries in connection with the authorization,
execution and delivery of this Agreement and the consummation of the
transactions contemplated herein, including, the Merger, and (iii) make all
necessary filings, and thereafter make any other required submissions, with
respect to this Agreement and the Merger, required under (A) the Exchange Act
and the rules and regulations thereunder, and any other applicable federal or
state securities laws, (B) the HSR Act and (C) any other applicable law;
PROVIDED that Parent and the Company shall cooperate with each other in
connection with the making of all such filings, including providing copies of
all such documents to the nonfiling party and its advisors prior to filing and,
if requested, to accept all reasonable additions, deletions or changes suggested
in connection therewith. The Company and Parent shall furnish all information
required for any application or other filing to be made pursuant to the rules
and regulations of any applicable Law (including all information required to be
included in the Proxy Statement, if required) in connection with the
transactions contemplated by this Agreement.
 
    SECTION 7.04 STOCK OPTIONS. The Company shall use its best efforts to obtain
the agreement of each holder of an employee stock option granted under the
Company's Stock Plans (whether or not exercisable) outstanding as of the date of
this Agreement, for the cancellation and settlement of such option as of the
Effective Time in consideration of the payment by Parent or Sub, as the case may
be, to such option holder of a dollar amount for each share of Company Common
Stock subject to such option equal to the Merger Consideration payable in
respect of a share of Company Common Stock less the applicable exercise price
per share of such option due and payable as of the Effective Time. All such
payments to optionees shall be subject to applicable withholding taxes. At or
immediately prior to the Closing, Parent or Sub, as the case may be, shall
deposit or cause to be deposited with the Paying Agent in trust for the benefit
of such option holders the cash necessary to allow the Paying Agent to pay the
amounts due under this Section 7.04 as of the Effective Time.
 
    SECTION 7.05 ISRA. The Company will comply with applicable requirements of
ISRA in connection with the transactions contemplated by this Agreement, and the
Company will bear all costs associated therewith until such time as all ISRA
requirements have been satisfied and evidenced by documentation from the New
Jersey Department of Environmental Protection ("NJDEP"). If required, such
compliance will include: (i) obtaining NJDEP approval of a negative declaration
or approval and implementation of a remedial action work plan to the
satisfaction of NJDEP, or entry into a remediation agreement with
 
                                       22
<PAGE>
NJDEP and (ii) furnishing any remediation funding source required by NJDEP.
Prior to taking or omitting any action with respect to compliance with
applicable requirements of ISRA (including, but not limited to, submitting any
required document to NJDEP), the Company shall notify Parent and provide Parent
with an opportunity to consult with and to inform the Company as to the
reasonableness of its actions or omissions; PROVIDED, HOWEVER, that the Company
shall not, on or prior to the Effective Time, take or omit any such action, the
result of which would be to bind or commit the Surviving Corporation after the
Effective Time, without the prior written consent of Parent (except that Parent
shall not unreasonably withhold its consent to the Company's entering into a
customary remediation agreement with the NJDEP providing for remediation
following the Effective Time).
 
    SECTION 7.06 COMPANY DEBT. Parent shall provide or cause to be provided to
the Company on a timely basis in connection with the transactions contemplated
hereby substitute working capital financing and funds or financing sufficient to
repay in full the Company Debt as provided in Section 1.01(b) hereof, shall
cause the Company at or prior to the Effective Time to repay in full its
indebtedness to Von Roll Holding AG and shall obtain the release of Von Roll
from the Tube City Guarantee.
 
    SECTION 7.07 NO SOLICITATION. (a) The Company shall not, nor shall it
authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or other
representative or agent retained by it or any subsidiary to, directly or
indirectly, (i) solicit, initiate or knowingly encourage the submission of any
Takeover Proposal (as defined below) or (ii) participate in any discussions or
negotiations regarding, or furnish to any person any nonpublic information with
respect to, or taken any other action designed or reasonably likely to
facilitate any inquiries or the making of any proposal that constitutes any
Takeover Proposal; provided, however, that if, at any time prior to the
acceptance for payment of Shares pursuant to the Offer, the Board of Directors
of the Company determines in good faith, after consultation with outside
counsel, that it is reasonably advisable to do so in order to comply with its
fiduciary duties to the Company's stockholders under applicable law, the Company
may, in response to a Takeover Proposal which was not solicited subsequent to
the date hereof, and subject to compliance with Section 7.07(c), (x) furnish
information with respect to the Company to any person pursuant to a customary
confidentiality agreement and (y) participate in discussions and negotiations
regarding such Takeover Proposal. Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in the preceding
sentence by any director, officer or employee of the Company or any of its
subsidiaries or any investment banker, financial advisor, attorney, account or
other representative or agent of the Company or any of its subsidiaries shall be
deemed to be a breach of this Section 7.07(a) by the Company. For purposes of
this Agreement, "TAKEOVER PROPOSAL" means any inquiry, proposal or offer from
any person relating to any direct or indirect acquisition or purchase of a
substantial amount of assets of the Company and its subsidiaries, taken as a
whole (other than the purchase of the Company's products in the ordinary course
of business), or more than 40% interest in the total voting securities of the
Company or any of its subsidiaries or any tender offer or exchange offer that if
consummated would result in any person beneficially owing 40% or more of any
class of equity securities of the Company or any of its subsidiaries or any
merger, consolidation, business combination, sale of substantially all assets,
recapitalization, liquidation, dissolution or similar transaction involving the
Company or any of its subsidiaries, other than the transactions contemplated by
this Agreement.
 
    (b) Except as set forth in this Section 7.07 neither the Board of Directors
of the Company nor any committee thereof shall (i) withdraw or modify, or
propose to withdraw or modify, in a manner adverse to Parent, the approval or
recommendation by such Board of Directors or such committee of the Offer, the
Merger or this Agreement, (ii) approve or recommend, or propose publicly to
approve or recommend, any Takeover Proposal or (iii) cause the Company to enter
into any letter of intent, agreement in principle, acquisition agreement or
other similar agreement (each, an "Acquisition Agreement") related to any
Takeover Proposal. Notwithstanding the foregoing, in the event that prior to the
acceptance for payment of Shares pursuant to the Offer the Board of Directors of
the Company determines in good faith, after consultation with outside counsel,
that it is reasonably advisable to do so in order to comply with its
 
                                       23
<PAGE>
fiduciary duties to the Company's stockholders under applicable law, the Board
of Directors of the Company may, in response to an unsolicited Superior Proposal
(as defined below) (subject to the following proviso), (x) withdraw or modify
its approval or recommendation of the Offer, the Merger or this Agreement or (y)
approve or recommend any such Superior Proposal if concurrently with such
approval or recommendation the Company terminates this Agreement and enters into
an Acquisition Agreement with respect to a Superior Proposal; provided, that in
the case of this clause (y), only at a time that is after the later of (i) the
third business day following Parent's receipt of written notice advising Parent
that the Board of Directors of the Company has received a Superior Proposal,
specifying the material terms of such Superior Proposal and identifying the
person making such Superior Proposal and (ii) in the event of any amendment to
the price or any material term of a Superior Proposal, one business day
following Parent's receipt of written notice containing the material terms of
such amendment, including any change in price (it being understood that each
further amendment to the price or any material terms of a Superior Proposal
shall necessitate an additional written notice to Parent and an additional one
business day period prior to which the Company can take the actions set forth in
clause (y) above.). For purposes of this Agreement, a "SUPERIOR PROPOSAL" means
any bona fide Takeover Proposal made by a third party (i) that is on terms which
the Board of Directors of the Company determines in its good faith judgment
(based on consultation with the Company's financial advisor) to be more
favorable to the Company's stockholders than the Offer and the Merger and (ii)
for which financing, to the extent required, is then committed or which, in the
good faith judgment of the Board of Directors of the Company, is capable of
being obtained by such third party.
 
    (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 7.07, the Company shall promptly advise Parent
orally and in writing of any request for nonpublic information (except in the
ordinary course of business and not in connection with a possible Takeover
Proposal) or of any Takeover Proposal known to it, the material terms and
conditions of such request or Takeover Proposal and the identity of the person
making such request or Takeover Proposal. The Company will promptly inform
Parent of any material change in the details (including amendments or proposed
amendments) of any such request or Takeover Proposal.
 
    (d) Nothing contained in this Agreement shall prohibit the Company from
taking and disclosing to its stockholders a position contemplated by Rule 14d-9
or Rule 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to the Company's stockholders if, in the good faith judgment of the
Board of Directors of the Company, after consultation with outside counsel,
failure so to disclose would be inconsistent with applicable law; PROVIDED,
HOWEVER, neither the Company nor its Board of Directors nor any committee
thereof shall, except as permitted by this Section 7.07, withdraw or modify, or
propose to withdraw or modify, its position with respect to the Offer, the
Merger or this Agreement or approve or recommend, or propose to approve or
recommend, a Takeover Proposal.
 
    SECTION 7.08 (A) FEES AND EXPENSES. Except as provided below in this Section
7.08, all fees and expenses in connection with the Offer, the Merger, this
Agreement and the transactions contemplated hereby shall be borne solely and
entirely by the party incurring such fees and expenses, whether or not the Offer
or the Merger are consummated.
 
    (b) The Company shall pay, or cause to be paid, to Parent the amount of
$5,000,000 (the "Termination Fee") under the circumstances and at the times set
forth as follows:
 
        (i) if the Company terminates this Agreement under Section 9.01(e), the
    Company shall pay 50% of the Termination Fee simultaneously with such
    termination, and 50% of the Termination Fee upon consummation of the
    transactions contemplated by the Superior Proposal giving rise to the
    Company's right to terminate this Agreement under Section 9.01(e), or upon
    the earlier consummation of another Company Acquisition (as defined in
    paragraph 7.08(c) below) provided that such other Company Acquisition is
    consummated within twelve months following termination of this Agreement;
 
                                       24
<PAGE>
        (ii) if Parent or Sub terminates this Agreement under Section 9.01(d)
    and in addition, if within twelve months after such termination the Company
    shall enter into an Acquisition Agreement providing for a Company
    Acquisition or the Company shall recommend to its stockholders that they
    accept a Company Acquisition of the type referred to in Section
    7.08(c)(iii), the Company shall pay (A) 50% of the Termination Fee
    simultaneously with the entering into of such Acquisition Agreement of
    making of such recommendation and (B) 50% of the Termination Fee upon
    consummation of the Company Acquisition which was the subject of such
    Acquisition Agreement or recommendation, or upon the consummation, prior to
    the expiration of such twelve month period, of any other Company Acquisition
    (it being understood that if any Company Acquisition shall be consummated
    within such twelve month period and the Company shall not have paid any
    amount pursuant to clause (A) above, that upon consummation of such Company
    Acquisition the Company shall pay 100% of the Termination Fee); and
 
       (iii) if, at the time of any termination of this Agreement pursuant to
    Section 9.01(b)(i) (as a result of a failure to obtain the Minimum
    Condition) or Section 9.01(c), any person shall have publicly announced a
    proposal to effect a Company Acquisition and if, within twelve months after
    such termination, the Company shall enter into an Acquisition Agreement
    providing for a Company Acquisition or the Company shall recommend to its
    stockholders that they accept a Company Acquisition of the type referred to
    in Section 7.08(c)(iii), the Company shall pay (A) 50% of the Termination
    Fee simultaneously with the entering into of such Acquisition Agreement or
    making of such recommendation and (B) 50% of the Termination Fee upon
    consummation of the Company Acquisition which was the subject of such
    Acquisition Agreement or recommendation, or upon the consummation, prior to
    the expiration of such twelve month period, of any other Company Acquisition
    (it being understood that if any Company Acquisition shall be consummated
    within such twelve month period and the Company shall not have paid any
    amount pursuant to clause (A) above, that upon consummation of such Company
    Acquisition the Company shall pay 100% of the Termination Fee.
 
    (c) For purposes of this Agreement a "COMPANY ACQUISITION" shall mean any of
the following transactions (i) a merger, consolidation, business combination or
a recapitalization pursuant to which the stockholders of the Company immediately
preceding such transaction hold less than 60% of the equity interests in the
surviving or resulting entity of such transaction (other than the transactions
contemplated by this Agreement); (ii) a sale by the Company of assets (excluding
the sale of the Company's products in the ordinary course of business)
representing in excess of 40% of the fair market value of the Company
immediately prior to such sale or the issuance by the Company to any person or
group of shares representing in excess of 40% of the then outstanding shares of
capital stock of the Company (other than in connection with an underwritten
public offering); or (iii) the acquisition by any person or group, by way of a
tender offer, exchange offer, or by way of open market purchases of beneficial
ownership of 40% or more of the then outstanding shares of capital stock of the
Company.
 
    SECTION 7.09 PUBLIC ANNOUNCEMENTS. Unless otherwise required by applicable
law, Parent and the Company shall consult with each other before issuing any
press release or otherwise making any public statement with respect to the
Merger and shall not issue any such press release or make any such public
statement prior to such consultation.

prior to the Effective Time, whether before or after approval of the terms of
this Agreement by the stockholders of the Company (provided, however, that if
Shares are purchased pursuant to the Offer, neither Parent nor Sub may in any
event terminate this Agreement):
 
    (a) by mutual written consent of Parent and the Company;
 
    (b) by either Parent or the Company:
 
        (i) if Sub shall not have accepted for payment and Shares pursuant to
    the Offer prior to May 5, 1998; provided, however, that the right to
    terminate this Agreement pursuant to this Section 9.01(b)(i) shall not be
    available to (1) Parent, if Sub shall have breached its obligations under
    the second to the last sentence of Section 1.01(a) or (2) any party whose
    failure to perform any of its obligations under this Agreement results in
    the failure of any such condition or if the failure of such condition
    results from facts or circumstances that constitute a willful breach of
    representation or warranty under this Agreement by such party; or
 
        (ii) if any Governmental Entity shall have issued an order, decree or
    ruling or taken any other action permanently enjoining, restraining or
    otherwise prohibiting the acceptance for payment of, or payment for, Shares
    pursuant to the Offer or the Merger and such order, decree or ruling or
    other action shall have become final and nonappealable;
 
    (c) by Parent or Sub prior to the purchase of Shares pursuant to the Offer
in the event of a breach or failure to perform by the Company of any
representation, warranty, covenant or other agreement contained in this
Agreement which (i) would give rise to the failure of a condition set forth in
paragraph (e) or (f) of Exhibit A and (ii) cannot be or has not been cured
within 30 days after the giving of written notice to the Company;

Section 7.08 (it being understood that that, as provided in Section 7.07(b), the
Company will be required to terminate this Agreement); or
 
    (f) by the Company in the event of a material breach or failure to perform
in any material respect by Parent or Sub of any representation, warranty,
covenant or other agreement contained in this Agreement which cannot be or has
not been cured within 30 days after the giving of written notice to Parent and
Sub.

    SECTION 9.02. EFFECT OF TERMINATION. In the event of a termination of this
Agreement by either the Company or Parent or Sub as provided in Section 9.01,
this Agreement shall forthwith become void and there shall be no liability or
obligation on the part of Parent, Sub or the Company or their respective
officers or directors, except with respect to the last sentence of Section
1.02(c), Section 4.18, Section 5.05, the last sentence of Section 7.02, Section
7.06, this Section 9.02 and Article X; provided, however, that nothing herein
shall relieve any party for liability for any willful breach hereof.
 
    SECTION 9.03. AMENDMENT. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto, duly
authorized by action taken at any time before or after obtaining the Company
Stockholder Approval. After the purchase of Shares pursuant to the Offer, no
amendment shall be made which decreases the Merger Consideration. After the
Company Stockholder Approval, no amendment shall be made which by law requires
further approval by such stockholders without obtaining such further approval.
Prior to the Effective Time, the written consent of Von Roll shall be required
to (i) amend or terminate this Agreement, (ii) exercise or waive any of the
Company's rights or remedies under this Agreement, (iii) extend the time for

Directors, may, to the extent legally allowed, subject to Section 9.03, (i)
extend the time for the performance of any of the obligations or other acts of
the other parties hereto, (ii) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto or
(iii) waive compliance with any of the agreements or conditions contained
herein. Any agreement on the part of a party hereto to any such extension or
waiver shall be valid only if set forth in a written instrument signed on behalf
of such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of those
rights.

(as extended, if required, pursuant to the second to the last sentence of
Section 1.01(a)) and before the acceptance of such Shares for payment or the
payment therefor, any of the following conditions exists and is continuing and
does not result principally from the breach by Parent or Sub of any of their
obligations under this Agreement:
 
        (a) there shall be instituted or pending by any Governmental Entity any
    suit, action or proceeding (i) challenging the acquisition by Parent or Sub
    of any Shares under the Offer, seeking to restrain or prohibit the making or

    to impose material limitations on the ability of Parent or Sub to acquire or
    hold, or exercise full rights of ownership of, any Shares to be accepted for

    the Offer or the Merger, by any Governmental Entity or court, other than the
    application to the Offer or the Merger of ISRA and any applicable waiting
    periods under the HSR Act, that would result in any of the consequences
    referred to in clauses (i) through (iv) of paragraph (a) above;
 
        (c) there shall have occurred any material adverse change with respect
    to the Company since the date of this Agreement;
 
        (d) the Board of Directors of the Company or any committee thereof shall
    have withdrawn or modified in a manner adverse to Parent or Sub its approval
    or recommendation of the Offer or the Merger or its adoption of this
    Agreement, or approved or recommended any Takeover Proposal;
 
        (e) any of the representations and warranties of the Company set forth
    in this Agreement that are qualified as to materiality shall not be true and
    correct or any such representations and warranties that are not so qualified
    shall not be true and correct in any material respect, in each case at the
    date of this Agreement and at the scheduled or extended expiration of the
    Offer;
 
                                       31
<PAGE>
        (f) the Company shall have failed to perform in any material respect any
    material obligation or to comply in any material respect with any material
    agreement or material covenant of the Company to be performed or complied
    with by it under this Agreement;
 
        (g) Parent and Sub shall not have received a certificate of the

it inadvisable to proceed with such acceptance of Shares for payment or the
payment therefor.
 
    Notwithstanding anything contained herein, (i) the conditions set forth in
clause (e) above shall be deemed not fulfilled only if the respects in which the
representations and warranties made by the Company (without giving effect to any
"materiality" limitations or references to "material adverse effect" set forth
therein) are inaccurate would have a material adverse effect on the Company, and
(ii) if the condition set forth in clause (f) is not fulfilled, Sub shall not be
obligated to purchase and pay for any Shares so long as such condition remains
unfulfilled, but Sub may not terminate the Offer due solely to such failure
until 30 days after it gives written notice to the Company of such
nonfulfillment and such nonfulfillment is not cured by the end of such 30-day
period.
 
    The foregoing conditions are for the sole benefit of Parent and Sub and
(except for the Minimum Condition) may, subject to the terms of this Agreement,
be waived by Parent and Sub in whole or in part at any time and from time to
time in their sole discretion. The failure by Parent or Sub at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to particular facts and
circumstances shall not be deemed a waiver with respect to any other facts and
circumstances and each such right shall be deemed an ongoing right that may be
asserted at any time and from time to time. Terms used but not defined herein
shall have the meanings assigned to such terms in the Agreement to which this
Exhibit A is a part.

    This Stockholder Agreement (the "AGREEMENT") made as of this 21st day of
November, 1997, by and between CO-STEEL INC., a Canadian corporation ("BUYER"),
and VON ROLL HOLDING AG, a Swiss corporation (formerly, Von Roll AG,
"STOCKHOLDER").
 
    WHEREAS, concurrently with the execution and delivery of this Agreement,
Buyer, CO-STEEL MERGER CORPORATION, a Delaware corporation and an indirect
wholly-owned subsidiary of Buyer ("MERGER SUB"), and NEW JERSEY STEEL

Offer Agreement and Agreement and Plan of Merger dated the date hereof (the
"TENDER AGREEMENT"), pursuant to which, among other things, Buyer is agreeing to
make a tender offer (the "OFFER") for all of the outstanding shares of common
stock, par value $.01 per share, of the Company (the "COMPANY COMMON STOCK") at
$23.00 per share (or such higher price as may be paid in the Offer) and
following the Offer, Merger Sub will be merged with and into the Company (the
"MERGER");
 
    WHEREAS, as a result of the Offer and Merger, the Company will become an
indirect wholly-owned subsidiary of Buyer, and the Company Common Stock not
tendered to and purchased by Buyer in the Offer will be converted into the right
to receive in cash the per share price paid in the Offer, subject to the terms
and conditions of the Tender Agreement; and
 
    WHEREAS, Stockholder is the record and ultimate beneficial owner of an
aggregate of 3,561,500 shares of Company Common Stock which it holds through its
VON ROLL STEEL HOLDING AG subsidiary;
 
    NOW, THEREFORE, to induce Buyer to enter into the Tender Agreement and in
consideration of the aforesaid and the mutual representations, warranties,
covenants and agreements set forth herein and in the Tender Agreement, the
parties hereto agree as follows:
 
    1. TENDER OF SHARES. Stockholder hereby agrees to validly tender (or cause
to be validly tendered), and not to withdraw, pursuant to and in accordance with
the terms of the Offer, not later than the fifth business day after commencement
of the Offer pursuant to Section 1.01 of the Tender Offer Agreement and Rule
14d-2 under the Exchange Act, all of the 3,561,500 shares of the Company owned
by it (and any shares acquired by Stockholder in any capacity after the date
hereof and prior to the termination of this Agreement by means of purchase,
dividend, distribution or in any other way, collectively, the "SHARES").
Stockholder hereby acknowledges and agrees that Buyer's obligation to accept for
payment and pay for the Shares in the Offer is subject to the terms and
conditions of the Offer.
 
    2. SALE AND PURCHASE OTHER THAN PURSUANT TO OFFER In the event the Shares
are not purchased by Buyer pursuant to the Offer because the Offer is terminated
for any reason other than a failure of an Offer Condition (as defined in the
Tender Agreement) other than condition (d) thereof, Stockholder hereby agrees to
sell, transfer and convey the Shares to Buyer, and Buyer hereby agrees to
purchase, acquire and accept the Shares from Stockholder, at a purchase price of
$23.00 per share (the "PURCHASE PRICE"), all subject to the terms and conditions
of this Agreement. In addition, at the time of the purchase and sale of the
Shares pursuant to this Section 2, Buyer hereby agrees that it (i) will purchase
from Stockholder the outstanding subordinated loans to the Company held by
Stockholder made pursuant to that certain Credit Agreement dated June 6, 1996
between the Company and Stockholder, at the face amount thereof, plus all
interest accrued but unpaid to the date of such purchase, (ii) will thereafter

Company's obligations to PNC Bank under that certain Loan and Security Agreement
dated June 6, 1996, if required by said lender and (iii) will provide, or cause
the Company to provide, Tube City Inc. a substitute guarantee or otherwise act

Notwithstanding the foregoing, Buyer shall deduct and withhold from the

undertake the defense thereof by representatives chosen by it;
 
    (ii) If the indemnifying party, within a reasonable time after notice of any
such Third-Party Claim, fails to defend the indemnified party against which such
Third-Party Claim has been asserted, the indemnified party shall (upon further
notice to the indemnifying party) have the right to undertake the defense,
compromise or settlement of such Third-Party claim on behalf of and for the
account and risk of the indemnifying party subject to the right of the
indemnifying party to assume the defense of such Third-Party Claim at any time
prior to settlement, compromise or final determination thereof; and
 
    (iii) Any provision hereof to the contrary notwithstanding, (A) if there is
a reasonable probability that a Third-Party Claim may materially and adversely
affect the indemnified party other than as a result of money damages or other
money payments, the indemnified party shall have the right, at its own cost and
expense, to defend, compromise or settle such Third-Party Claim; PROVIDED,
HOWEVER, that if such Third-Party Claim is settled without the indemnifying
party's consent, the indemnified party shall be deemed to have waived all rights
hereunder against the indemnifying party for money damages arising out of such
Third-Party Claim; and (B) the indemnifying part shall not, without the written
consent of the indemnified party, settle or compromise any Third-Party Claim or
consent to the entry of any judgment which does not include as an unconditional
term thereof the giving by the claimant or the plaintiff to the indemnified
party a release from all liability in respect to such Third-Party Claim.

                          NEW JERSEY STEEL CORPORATION
 
    New Jersey Steel Corporation, a corporation organized and existing under the
laws of the State of Delaware (the "Corporation"), hereby certifies as follows:
 
    1.  The name of the Corporation is New Jersey Steel Corporation. The date of
filing its original Certificate of Incorporation with the Secretary of State is
November 18, 1976 under the name of Steel Holdings Corporation. An amendment to
the Certificate of Incorporation was filed December 1, 1978, changing the
corporate name to the present one.
 
    2.  This Restated Certificate of Incorporation restates and integrates and
further amends the Certificate of Incorporation of the Corporation by (i)
amending ARTICLE FOURTH to authorize additional shares of Class A Common Stock
(redesignated "Common Stock") and Class B Common Stock, to provide, under
certain circumstances, for the automatic conversion of the Class B Common Stock
into Common Stock, and to authorize a new class of Preferred Stock, par value
$.01 per share, to be issued in series; and (ii) adding a new ARTICLE FIFTH
relating to liability of directors in certain circumstances; and (iii) amending
ARTICLE SEVENTH by inserting the words "authorized or" immediately preceding the
word "permitted" in the second line thereof and by placing the words "officers
and directors" instead of the words "persons" in the third line thereof.
 
    3.  The text of the Certificate of Incorporation of the Corporation, as
amended, or supplemented heretofore is further amended hereby to read as herein
set forth in full:
 
    FIRST:  The name of the corporation is
 
NEW JERSEY STEEL CORPORATION
 
    SECOND:  The address of its registered office in the State of Delaware is
Corporation Trust Center, 1209 Orange Street, Wilmington, County of New Castle,
Delaware 19801. The name of its registered agent at that address is The
Corporation Trust Company.
 
    THIRD:  The purpose of the corporation is to engage in any lawful act or
activity for which corporation may be organized under the General Corporation
Law of Delaware.
 
    FOURTH:  (A) The aggregate number of shares of all classes of stock which
the Corporation shall have authority to issue is Twenty Million (20,000,000)
shares, divided into classes as follows:
 
        (1)  Fourteen Million Five Hundred Thousand (14,500,000) shares of
    Common Stock, par value $.01 per share (hereinafter called the "Common
    Stock");
 
        (2)  Five Hundred Thousand (500,000) shares of Class B Non-Voting Common
    Stock, par value $.01 per share (hereinafter called "Class B Non-Voting
    Common Stock"); and
 
        (3)  Five Million (5,000,000) shares of Preferred Stock, par value $.01
    per share (herein called the "Preferred Stock"), to be issued in series.
 
    (B)  The following is a statement of the designations, and the powers,
preferences and rights, and the qualifications, limitations or restrictions, in
respect of the stock of the Corporation:
 
        (1)  Common Stock and Class B Non-Voting Common Stock shall be identical
    in all respects except with respect to voting rights. With respect to
    voting, except as otherwise provided by law and this Certificate of
    Incorporation, (a) the holders of Common Stock shall vote together as a
    class on all matters to be voted on by stockholders of the Corporation,
    including the election of all directors of the Corporation, with each holder
    of Common Stock entitled to one vote per share, and (b) the holders of Class
    B Non-Voting Common Stock shall not be entitled to vote. Upon the closing of
    the sale to the public by the company of shares of Common Stock pursuant to
    an offering registered under the Securities Act of 1933 (a "Public Sale"),
    each outstanding share of Class B Common Stock shall be
<PAGE>
    converted into, and shall automatically become, a share of Common Stock and
    the authorized but unissued Class B Common Stock shall become authorized and
    unissued Common Stock and the Class B Common Stock shall no longer be an
    authorized class of capital stock of the Corporation.
 
        (2)  The shares of Preferred Stock may be issued in one or more series,
    and each series shall be so designated as to distinguish the shares thereof
    from the shares of all other series. Authority is hereby expressly granted
    to the Board of Directors of the Corporation to fix, subject to the
    provisions herein set forth, before the issuance of any shares of a
    particular series, the number, designation, and relative rights, preferences
    and limitations of the shares of such series including (1) voting rights, if
    any, which may include the right to vote separately and the right to vote
    together as a single class with the Common Stock and any other series of the
    Preferred Stock with the number of votes per share accorded to shares of
    such series being the same as or different from that accorded to such other
    shares, (2) the divided rate per annum, if any, and the terms and conditions
    pertaining to dividends and whether such dividends shall be cumulative, (3)
    the amount or amounts payable upon such shares and the priority thereof, if
    any, in the event of voluntary or involuntary liquidation, (4) the
    redemption price or prices, if any, and the terms and conditions of the
    redemption, (5) sinking fund provisions, if any, for the redemption or
    purchase of such shares, (6) the terms and conditions on which such shares
    are convertible, in the event the shares are to have conversion rights, and
    (7) any other rights, preferences and limitations pertaining to such series
    which may be fixed by the Board of Directors pursuant to the General
    Corporation Law of the State of Delaware.
 
    FIFTH:  No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as director. This provision, however, shall not eliminate or limit the
liability of a director, (i) for any breach of the director's duty of loyalty to
the Corporation or its stockholders, (ii) for acts or omission not in good faith
or which involve intentional misconduct or knowing violation of law, (iii) under
Section 174 of the General Corporation Law of the State of Delaware, or (iv) for
any transaction from which the director derived an improper personal benefit.
 
    SIXTH:  The by-laws of the corporation may be made, altered, amended,
changed, added to or repealed by the Board of Directors without the assent or
vote of the stockholders.
 
    SEVENTH:  The corporation shall, to the full extent authorized or permitted
by Section 145 of the Delaware General Corporation Law of the State of Delaware,
as amended from time to time, indemnify all officers and directors whom it may
indemnify pursuant thereto.
 
    EIGHTH:  The corporation reserves the right to amend, alter, change or
repeal any provision contained in this certificate in the manner now or
hereafter prescribed by law, and all rights and powers conferred herein on
stockholders, directors and officers are subject to this reserved power.
 
    4.  This Restated Certificate of Incorporation was duly adopted by written
consent of the sole stockholder in accordance with the applicable provisions of
Sections 228, 242 and 245 of the General Corporation Law of the State of
Delaware and written notice of the adoption of this Restated Certificate of
Incorporation has been given as provided by Section 228 of the General
Corporation Law of the State of Delaware to sole stockholder entitled to such
notice.

                                INDEMNIFICATION
 
    Section 6.01.  INDEMNIFICATION.  To the extent permitted and in the manner
provided by law, the Company shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative, or investigative by
reason of the fact that he is or was a director or officer of the Company or is
or was serving at the request of the Company as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding. The foregoing rights of indemnification shall not be
deemed exclusive of any other rights to which any person seeking indemnification
may be entitled under any agreement, vote of stockholders or disinterested
Directors or otherwise, and shall continue as to a person who has ceased to be a
Director or officer and shall inure to the benefit of the heirs, executors and
administrators of such a person.
 
    Section 6.02.  INSURANCE.  By action of the Board of Directors,
notwithstanding any interest of the Directors in the action, the Company may
purchase and maintain insurance, in such amounts as the Board of Directors may
deem appropriate, on behalf of any person who is or was a Director, officer,
employee or agent of the Company, or is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture or other enterprise, against any liability asserted
against him and incurred by him in any such capacity, or arising out of his
status as such, whether or not the Company would have the power to indemnify him
against such liability under applicable provisions of law.

The Board of Directors
New Jersey Steel Corporation
 
Gentlemen:
 
    BT Wolfensohn has acted as financial advisor to New Jersey Steel Corporation
(the "Company") in connection with the proposed acquisition of the Company by
Co-Steel Inc. ("Parent") pursuant to an Agreement and Plan of Merger (the
"Merger Agreement") pursuant to which (i) Co-Steel Merger Corporation, a wholly
owned subsidiary of Parent (the "Acquisition Sub") will commence a tender offer
(the "Tender Offer") for all the outstanding shares of the Company's common
stock, par value $.01 per share, (the "Company Shares"), at a price of $23.00
per share (the "Per Share Price"), net to the seller in cash, and (ii) after the
consummation of the Tender Offer, Acquisition Sub will merge with and into the
Company (the "Merger", and the Merger and the Tender Offer together, the
"Transaction"), and each Company Share not acquired in the Tender Offer, other
than Company Shares held in treasury or held by the Parent or any direct or
indirect wholly owned subsidiary of Parent or the Company or as to which
dissenters' rights have been perfected will be converted into the right to
receive in cash, without interest, the consideration per share paid in the
Tender Offer. The terms and conditions of the Transaction are more fully set
forth in the Merger Agreement.
 
    You have requested BT Wolfensohn's opinion, as investment bankers, as to the
fairness, from a financial point of view, of the Per Share Price to the
Company's stockholders (other than Von Roll Holding, AG ("Von Roll")).
 
    In connection with BT Wolfensohn's role as financial advisor to the Company
and in arriving at its opinion, BT Wolfensohn has, among other things:
 
    (i) reviewed the publicly available filings concerning the Company as well
        as the consolidated financial statements of the Company for recent years
        and interim periods to date and certain other relevant financial and
        operating data of the Company available from public sources or provided

Accordingly, for purposes of its opinion, BT Wolfensohn has assumed and relied

PRESS RELEASE
 
    CONTACT:  GARY A. GIOVANNETTI
    PRESIDENT AND CHIEF EXECUTIVE OFFICER
 
CO-STEEL INC. TO ACQUIRE NEW JERSEY STEEL CORPORATION
 
    SAYREVILLE, NEW JERSEY -- November 21, 1997, -- Co-Steel Inc. (C:CEI) and
New Jersey Steel Corporation (NASDAQ:NJST) announced today that they have
entered into a definitive tender offer agreement providing for the acquisition
of NJST by Co-Steel. Pursuant to the tender offer, Co-Steel is offering to pay
$23.00 in cash for each share of NJST common stock tendered.
 
    Under the terms of the tender offer agreement, Von Roll Holding AG, the
holder of 60.2% of the outstanding shares of NJSCO, has agreed to tender the
3,561,500 shares of NJST common stock owned by it to Co-Steel in response to the
offer.
 
    New Jersey Steel Corporation's Board of Directors unanimously approved the
transaction and recommended it to the shareholders. A Board spokesperson stated
that this sale represents the culmination of a turnaround effort spanning
several years. After the Company made a commitment to remain in New Jersey, it
expended some $65,000,000 on a new Consteel manufacturing process, and other
capital improvements, revamped the senior management and substantially improved
productivity and financial results, before accepting the present purchase offer.
 
    Following the tender offer, there will be a merger of a wholly owned
subsidiary of Co-Steel, with and into NJST and any remaining NJST Common Stock
will be converted into the right to receive $23.00 per share.
 
    The offer is subject to certain conditions, including the expiration of the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended. This transaction is expected to close in early January,
1998.
 
    Co-Steel is one of the world's largest mini-mill steel producers with
current annual capacity of 3.4 million tons of finished steel. With plants in
Canada, the United States and Europe, Co-Steel manufactures and markets a wide
variety of steel products used principally in the construction, automotive,
appliance, machinery and equipment industries. Co-Steel's common shares are
listed on the Toronto Stock Exchange and the Montreal Exchange. NJST owns and
operates a mini-mill in Sayreville, New Jersey, producing steel products. The
principal product manufactured by NJST's mill is rebar, which is used in the
construction industry. NJST's common stock is listed on the NASDAQ National
Market System.
