Item 3. Source and Amount of Funds or Other Consideration.

            On September 27, 1999, Gerdau USA acquired 176 shares of common
stock of FLS Holdings from Kyoei Steel Ltd. a Japanese corporation ("Kyoei"),

stock beneficially owned by the Reporting Persons were converted into 9,000,000
shares of Common Stock. The transaction was consummated pursuant to a Stock
Purchase Agreement described in Item 6 (the "Stock Purchase Agreement"). Gerdau

$131,360,000 to be paid in three equal installments on March 17, 2000, September
18, 2000 and March 19, 2001 pursuant to three Promissory Notes described in Item
6 (the "Promissory Notes") supported by three stand-by Letters of Credit
described in Item 6 ("the "Letters of Credit"). A copy of the Stock Purchase
Agreement is attached hereto as Exhibit A and is incorporated herein by
reference. Copies of the Promissory Notes are attached hereto as Exhibits B-1,
B-2 and B-3 and are incorporated herein by reference. Copies of the Letters of
Credit are attached hereto as Exhibits C-1, C-2 and C-3 and are incorporated

            The Reporting Persons acquired a beneficial interest in the Common
Stock with a combination of cash on hand and borrowed funds. The borrowed funds
were loaned under the Loan Agreement described in Item 6 (the "Loan Agreement")
and the Promissory Notes. A copy of the Loan Agreement is attached hereto as
Exhibit D and is incorporated herein by reference.

Item 4. Purpose of Transaction.

            The Reporting Persons acquired a beneficial interest in the Common
Stock to gain control of the Issuer and to make the Issuer an operating
subsidiary of the Reporting Persons.

            In accordance with the provisions of the Articles of Incorporation
of the Issuer, upon consummation of the transaction, all shares of Class B
common stock of the Issuer automatically were converted into shares of Common
Stock. Therefore, there are no longer any holders of record of the Class B
common stock of the Issuer and such common stock has become eligible for
termination of its registration pursuant to Section 12(g)(4) of the Securities
Exchange Act of 1934, as amended.

            In connection with the acquisition of a beneficial interest in the
Common Stock, immediately prior to such acquisition, Koichi Takashima, Akihiko
Takashima, Ryutaro Yoshioka and Shuzo Hikita resigned from the Board of
Directors of the Issuer. They were replaced by Jorge Gerdau Johannpeter, Germano
Gerdau Johannpeter, Andre Bier Johannpeter and Carlos Joao Petry.

            The Reporting Persons reserve the right to exercise any and all of
their respective rights and privileges as beneficial securityholders of the
Issuer. However, except as set forth in this Item 4, the Reporting Persons have
no present plan or proposal that relates to or would result in (i) the
acquisition of additional securities or the disposition of securities of the
Issuer by any Reporting Person, (ii) an extraordinary corporate transaction,
such as a merger, reorganization, liquidation, or sale or transfer of a material
amount of assets involving the Issuer or any of its subsidiaries, (iii) any
change in the Issuer's present Board of Directors or management of the Issuer,
(iv) any material change in the Issuer's present capitalization or dividend
policy or any other material change in the Issuer's business or corporate
structure, (v) any change in the Issuer's charter or bylaws or other actions
that may impede the acquisition of control of the Issuer by any person, (vi) a
class of equity securities of the Issuer becoming eligible for termination of
registration pursuant to Section 12(g)(4) of the Securities Exchange Act of
1934, as amended, or a class of securities of the Issuer being delisted from a
national securities

exchange or ceasing to be authorized to be quoted in an inter-dealer quotation
system of a registered national securities association or (vii) any similar
action.

Item 5. Interest in Securities of the Issuer.

            (a) and (b). Under the definition of "beneficial ownership" as set
forth in Rule 13d-3 under the Securities Exchange Act, the Reporting Persons
currently have beneficial ownership of 9,000,000 shares of Common Stock of the
Issuer. This amount constitutes approximately 85% of the issued and outstanding
shares of Common Stock of the Issuer, based upon the total of 10,586,375 issued
and outstanding shares as reported in the Form 10-Q of the Issuer most recently
filed with the Securities and Exchange Commission for the quarter ended
September 30, 1999. The Reporting Persons have the sole power to direct the vote
of and sole power to direct the disposition of the 9,000,000 shares of Common
Stock. However, pursuant to a Pledge Agreement described in Item 6 (the "Pledge
Agreement"), FLS Holdings has agreed that after the occurrence of a Default
under such Pledge Agreement, The Toronto-Dominion Bank, as Agent, may exercise
all voting and corporate rights with respect to the 7,920,000 shares of Common
Stock pledged thereunder (the "Pledged Common Stock"). Also, the Pledge
Agreement provides that after the occurrence and during the continuance of a
Default thereunder the Agent may sell the Pledged Common Stock. A copy of the
Pledge Agreement is attached hereto as Exhibit E and is incorporated herein by
reference.

            (c) To the best of the knowledge of the Reporting Persons, except as
described in this Item 5, none of the Reporting Persons nor any director or
officer of a Reporting Person has effected any transaction in the Common Stock
during the past sixty days.

            (d) Any dividend made by the Issuer would be received by its parent
corporation, FLS Holdings. No person other than the Reporting Persons have the
right to direct the receipt of dividends made to FLS Holdings by the Issuer.
However, pursuant to a Shareholders Agreement described in Item 6 (the
"Shareholders Agreement"), FLS Holdings has agreed to distribute any dividends
made to it by the Issuer on a pro rata basis to Gerdau USA and Kyoei.

            Pursuant to the Pledge Agreement, after the occurrence of a Default
under the Pledge Agreement, The Toronto-Dominion Bank, as Agent, may exercise
all voting and corporate rights with respect to the Pledged Common Stock
(including those with respect to dividends). Also, the Pledge Agreement provides
that after the occurrence and during the continuance of a Default thereunder the
Agent may sell the Pledged Stock.

            A copy of the Shareholders Agreement is attached hereto as Exhibit F
and the Shareholders Agreement and the Pledge Agreement are incorporated herein
by reference.

            (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer.

CUSIP No. 03071V 10 9             SCHEDULE 13D

            The Reporting Persons and, to the best of the knowledge of the
Reporting Persons, the directors and executive officers of the Reporting
Persons, do not have any contract, arrangement, understanding or relationship
(legal or otherwise) with any person with respect to any securities of the
Issuer except as indicated in this Item 6.

            Stock Purchase Agreement.

            The Stock Purchase Agreement, dated as of September 27, 1999, by and
among Gerdau USA, Gerdau and Kyoei (the "Stock Purchase Agreement") provided for
the purchase of 176 of the 200 issued and outstanding shares of FLS Holdings by
Gerdau USA from Kyoei. Gerdau USA agreed to pay $261,360,000 for the shares of
FLS Holdings, $130,000,000 of which was paid at closing with $131,360,000 to be
paid in three equal installments. This transaction was consummated on September
27, 1999. Because FLS Holdings owns 9,000,000 shares of Common Stock, under the
definition of "beneficial ownership" as set forth in Rule 13d-3 of the
Securities Exchange Act, Gerdau USA and the other Reporting Persons are
beneficial owners of such 9,000,000 shares. A copy of the Stock Purchase
Agreement is attached hereto as Exhibit A and is incorporated herein by
reference.

            Promissory Notes.

            Three Promissory Notes, each dated September 27, 1999 (the
"Promissory Notes"), were delivered by Gerdau USA to Kyoei in connection with
the Stock Purchase Agreement. The Promissory Notes represent the three
installments of the purchase price to be paid under the Stock Purchase Agreement
after closing. Each Promissory Note is in the principal amount of $43,786,666,
and they are payable, respectively, on March 17, 2000, September 18, 2000 and
March 19, 2001. Copies of the Promissory Notes are attached hereto as Exhibits
B-1, B-2 and B-3 and are incorporated herein by reference.

            Letters of Credit.

            Three stand-by Letters of Credit, each dated September 24, 1999 (the
"Letters of Credit"), support the three Promissory Notes. Each was issued by The
Chase Manhattan Bank for Gerdau USA in favor of Kyoei in the amount of
$43,786,666. Copies of the Letters of Credit are attached hereto as Exhibits
C-1, C-2 and C-3 and are incorporated herein by reference.

            Loan Agreement.

            In connection with the purchase of shares of FLS Holdings under the
Stock Purchase Agreement, there was entered into an Amended and Restated Loan
Agreement dated as of November 8, 1996 as further amended and restated by
agreements dated as of December 18, 1998, September 27, 1999 and November 4,

<PAGE>

CUSIP No. 03071V 10 9             SCHEDULE 13D

to fund, in part, the acquisition of the shares of FLS Holdings by Gerdau USA,
which acquisition made the Reporting Persons beneficial owners of the Common
Stock. The loan facility consists of a 364 day Revolving Extendible Operating
Facility for Cdn.$75million and five year Non-Revolving Reducing Term Facility,
both bearing interest at a range of Canadian and U.S. dollar floating rates plus
margins. Both facilities are subject to early amortization, depending on the
applicable borrowing base calculation (for the Revolving Facility) and cash flow
sweep and other factors (in the case of the Term Facility), and to acceleration
on terms customary for facilities of this kind. A copy of the Loan Agreement is
attached hereto as Exhibit D and is incorporated herein by reference.

            Pledge Agreement.

            As a condition to the making of the loans under the Loan Agreement,
there was entered into a Stock Pledge Agreement, dated as of September 27, 1999
(the "Pledge Agreement"), by and between FLS Holdings and The Toronto-Dominion
Bank, as Agent. Pursuant to the Pledge Agreement, FLS Holdings pledged to the
Agent for the benefit of the Lenders under the Loan Agreement 7,920,000 shares
of Common Stock (the "Pledged Common Stock"). The Pledge Agreement provides that
after the occurrence of a Default thereunder FLS Holdings will permit the Agent
to exercise all voting and corporate rights relating to the Pledged Common
Stock. Also, after the occurrence and during the continuance of a Default under
the Pledge Agreement the Agent may sell the Pledged Common Stock. A copy of the
Pledge Agreement is attached hereto as Exhibit E and is incorporated herein by
reference.

            Shareholders Agreement.

            As a condition to closing under the Stock Purchase Agreement, there
was entered into a Shareholders Agreement made and entered into September 27,
1999 (the "Shareholders Agreement") by and among Gerdau USA, Kyoei and FLS
Holdings. In the Shareholders Agreement FLS Holdings agrees that if it receives
a dividend from the Issuer it will make a corresponding dividend on a pro rata
basis to Gerdau USA and Kyoei. The Shareholders Agreement also provides that
with respect to election of directors of the Issuer, all votes entitled to be
cast by FLS Holdings shall be cast to ensure that one nominee of Kyoei is a
member of the board of directors of the Issuer for so long as Kyoei holds at
least 5% of the issued and outstanding common stock of FLS Holdings. In
addition, the Shareholders Agreement provides: (i) for restrictions on transfer
of shares of FLS Holdings' common stock by Kyoei and Gerdau USA, (ii) Gerdau USA
with a right of first refusal to purchase any shares of FLS Holdings' common
stock offered for sale by Kyoei, (iii) Kyoei with a right to require Gerdau USA
to purchase all of the shares of FLS Holdings' common stock held by Kyoei and
(iv) Kyoei with certain rights to participate pro rata in any disposition of
shares of FLS Holdings' common stock by Gerdau USA. A copy of the Shareholders
Agreement is attached hereto as Exhibit F and is incorporated herein by
reference.

PROMISSORY NOTE

$43,786,666.66                                         September 27, 1999

      FOR VALUE RECEIVED the undersigned Gerdau USA Inc., a Delaware corporation
("Maker"), promises to pay to Kyoei Steel, Ltd. or its registered assigns
("Holder") at such place or manner as Holder may from time to time designate in
writing, in lawful money of the United States of America, the principal sum of
Forty-Three Million Seven Hundred Eighty-Six Thousand Six Hundred Sixty six and
66/100 Dollars ($43,786,666.66) together with interest from and after the date
hereof on the principal balance, at the rate hereinafter set forth herein, said
principal and interest being due and payable in full on March 17, 2000.

      Interest on the principal balance of this Note from time to time
outstanding and unpaid shall be computed on the basis of a 360-day year for the
actual number of days elapsed at an interest rate per annum equal to four and
eighty-nine hundredths percent (4.89%).

      In the event that the Interest Payment to Holder would be taxable outside
of Japan, Maker shall provide an additional payment, such that Holder would
receive the full amount of the Interest Payment on an after-tax basis (the
"Additional Payment'). At the request of Maker, each Holder shall provide Maker
from time to time on a timely basis with any forms or documentation as Maker may
reasonably require to establish an available exemption from or reduction in
withholding taxes that may be imposed on payments hereunder, so that such forms
or documentation are effective for all periods during which it is a Holder. Any
assignee hereof shall not be entitled to payment of an Additional Payment
hereunder that would be greater than the Additional Payment to which the initial
Holder hereof would be entitled, had it continued to hold this Promissory Note.

      To the extent permitted by law, any interest not paid when due hereunder
shall be added to the unpaid principal balance of Maker's indebtedness
hereunder, which additional amount shall thereafter accrue interest at the rate
per annum provided herein.

      Any Holder hereof may assign its rights under and to this Promissory Note
by notice hereof to Maker, and Maker shall promptly record such assignment in
the Register (defined below). From and after the notice of the transfer and
assignment hereof to Maker, the assignee shall be a party hereto and shall have
the rights of Holder hereunder. Maker shall maintain at its office a register
for the recordation of the names and addresses of Holder hereof and each
assignee (the "Register"). The entries in the Register shall be conclusive in
the absence of manifest error and Maker may treat each person whose name is
recorded in the Register pursuant

<PAGE>

                                                                     EXHIBIT B-1

to the terms hereof as Holder for all purposes hereof. All payments hereunder
and under the related Letter of Credit shall be made to the appropriate person
named in the Register.

      This Note may be prepaid in whole or in part at any time by the payment of
all accrued and unpaid interest on the principal amount prepaid.

      As security for the payment and performance of the obligations in this
Note, Maker has provided Holder with an irrevocable bank standby letter of
credit in favor of Holder, the original of which is attached hereto as Exhibit A
(the "Standby Letter of Credit"). The Standby Letter of Credit does not in any
way limit or reduce the obligations of Maker in this Note, and is additional
security to holder and not in lieu of remedies that Holder is provided herein.

      Each of the following events shall constitute an Event of Default
hereunder:

            (a) The failure of Maker to pay principal or interest when due
hereunder; or

            (b) The filing by Maker of a voluntary petition of bankruptcy or a
voluntary petition or answer seeking reorganization, arrangement, or
readjustment of its debts, or any other relief under the Bankruptcy Code, as
amended, or any other insolvency act or law, state or federal, now or hereafter
existing, or any agreement by Maker indicating consent to, approval or
acquiescence in any such petition or proceeding; or

            (c) The application by Maker or the consent or acquiescence of Maker
in the appointment of a receiver or trustee for all or a substantial part of any
of its property; or

            (d) The making by Maker of a general assignment for the benefit of
creditors; or

            (e) The inability of Maker or the admission of Maker in writing of
its inability to pay its debts as they mature; or

            (f) The filing of an involuntary petition against. Maker seeking
reorganization, arrangement or readjustment of its debts or for any other relief
under the Bankruptcy Code, as amended, or under any other insolvency act or law,
state or federal, now or hereafter existing, or the involuntary appointment of a
receiver or trustee of Maker for all or a substantial part of its property or
assets, or the issuance of a warrant of attachment or execution of similar
process against a substantial part of the property of Maker and the continuance
of such for thirty (30) days undismissed or undischarged.

      From and after an Event of Default and during the continuation thereof,
and upon demand for repayment of this Note, the principal balance due hereunder
shall bear interest at a rate equal to two and one half percent (2 1/2%) per
annum in excess of the rate of interest otherwise set out herein.

      From and after the occurrence of an Event of Default and during the
continuation thereof, Holder may, at its option, without any notice or demand
whatsoever, declare all obligations of Maker to Holder, including all
indebtedness evidenced by this Note, to be due and payable immediately and
Holder may proceed to collect such obligations forthwith including exercising
all of Holder's rights under the Standby Letter of Credit, plus all costs of
collection, including reasonable attorneys' fees if collected by and through an
attorney. It is further agreed that failure of Holder to exercise this option or
indulgence granted from time to time shall in no event be considered a waiver of
such option or estop Holder from exercising such option.

      MAKER, ITS SUCCESSORS OR ASSIGNS, AND ALL OTHER PERSONS LIABLE FOR THE
PAYMENT OF THIS NOTE, WAIVE PRESENTMENT FOR PAYMENT, DEMAND, PROTEST, AND NOTICE
OF DEMAND, DISHONOR, PROTEST, AND NONPAYMENT, AND CONSENT TO ANY AND ALL
RENEWALS, EXTENSIONS OR MODIFICATIONS THAT MIGHT BE MADE BY HOLDER AS TO THE
TIME OF PAYMENT OF THIS NOTE FROM TIME TO TIME.

      This Note is hereby expressly limited so that in no contingency or event
whatsoever shall the amount paid or agreed to be paid to Holder for the use,
forbearance or detention of the money advanced or to be advanced hereunder
exceed the highest lawful rate permissible under applicable law. If, from any
circumstances whatsoever, fulfillment of any provision hereof or of any other
agreement evidencing or securing the indebtedness, at the time performance of
such provision occurs, shall involve payment of interest in excess of that
authorized by law, the obligation to be fulfilled shall be reduced to the limit
so authorized by law, and if, from any circumstances, Holder shall ever receive
as interest an amount which would exceed the highest lawful rate applicable to
Borrower, such amount which would be excessive interest shall be applied to the
reduction of the unpaid principal balance of the indebtedness evidenced hereby
and not to the payment of interest.

      Holder shall not be deemed to waive any of its rights unless such waiver
be in writing and signed by Holder. No delay or omission by Holder in exercising
any of its rights shall operate as a waiver of such rights and a waiver in
writing on one occasion shall not be construed as a consent to a waiver of any
right or remedy on any future occasion.

      The word "Holder" as used herein shall include successors and registered
assigns of Holder, and all rights of Holder hereunder shall inure to the benefit
of its successors and registered assigns. All obligations of Maker shall bind
its transferees, successors, heirs, personal representatives and assigns.

      THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK (OTHER THAN CONFLICT OF LAWS PROVISIONS). MAKER HEREBY
CONSENTS TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE
STATE OF NEW YORK AND IRREVOCABLY AGREES THAT SUBJECT TO HOLDER'S SOLE AND

PROMISSORY NOTE

$43,786,666.66                                            September 27, 1999

      FOR VALUE RECEIVED the undersigned Gerdau USA Inc., a Delaware corporation
("Maker"), promises to pay to Kyoei Steel, Ltd. or its registered assigns
("Holder") at such place or manner as Holder may from time to time designate in
writing, in lawful money of the United States of America, the principal sum of
Forty-Three Million Seven Hundred Eighty-Six Thousand Six Hundred Sixty six and
66/100 Dollars ($43,786,666.66) together with interest from and after the date
hereof on the principal balance, at the rate hereinafter set forth herein, said
principal and interest being due and payable in full on March 19, 2001.

      Interest on the principal balance of this Note from time to time
outstanding and unpaid shall be computed on the basis of a 360-day year for the
actual number of days elapsed at an interest rate per annum equal to five and
three hundred seventy-five thousands percent (5.375%).

      In the event that the Interest Payment to Holder would be taxable outside
of Japan, Maker shall provide an additional payment, such that Holder would
receive the full amount of the Interest Payment on an after-tax basis (the
"Additional Payment'). At the request of Maker, each Holder shall provide Maker
from time to time on a timely basis with any forms or documentation as Maker may
reasonably require to establish an available exemption from or reduction in
withholding taxes that may be imposed on payments hereunder, so that such forms
or documentation are effective for all periods during which it is a Holder. Any
assignee hereof shall not be entitled to payment of an Additional Payment
hereunder that would be greater than the Additional Payment to which the initial
Holder hereof would be entitled, had it continued to hold this Promissory Note.

      To the extent permitted by law, any interest not paid when due hereunder
shall be added to the unpaid principal balance of Maker's indebtedness
hereunder, which additional amount shall thereafter accrue interest at the rate
per annum provided herein.

      Any Holder hereof may assign its rights under and to this Promissory Note
by notice hereof to Maker, and Maker shall promptly record such assignment in
the Register (defined below). From and after the notice of the transfer and
assignment hereof to Maker, the assignee shall be a party hereto and shall have
the rights of Holder hereunder. Maker shall maintain at its office a register
for the recordation of the names and addresses of Holder hereof and each
assignee (the "Register"). The entries in the Register shall be conclusive in
the absence of manifest error and Maker may treat each person whose name is
recorded in the Register pursuant

                                                                     EXHIBIT B-3

to the terms hereof as Holder for all purposes hereof. All payments hereunder
and under the related Letter of Credit shall be made to the appropriate person
named in the Register.

      This Note may be prepaid in whole or in part at any time by the payment of
all accrued and unpaid interest on the principal amount prepaid.

      As security for the payment and performance of the obligations in this
Note, Maker has provided Holder with an irrevocable bank standby letter of
credit in favor of Holder, the original of which is attached hereto as Exhibit A
(the "Standby Letter of Credit"). The Standby Letter of Credit does not in any
way limit or reduce the obligations of Maker in this Note, and is additional
security to holder and not in lieu of remedies that Holder is provided herein.

      Each of the following events shall constitute an Event of Default
hereunder:

            (a) The failure of Maker to pay principal or interest when due
hereunder; or

            (b) The filing by Maker of a voluntary petition of bankruptcy or a
voluntary petition or answer seeking reorganization, arrangement, or
readjustment of its debts, or any other relief under the Bankruptcy Code, as
amended, or any other insolvency act or law, state or federal, now or hereafter
existing, or any agreement by Maker indicating consent to, approval or
acquiescence in any such petition or proceeding; or

            (c) The application by Maker or the consent or acquiescence of Maker
in the appointment of a receiver or trustee for all or a substantial part of any
of its property; or

            (d) The making by Maker of a general assignment for the benefit of
creditors; or

            (e) The inability of Maker or the admission of Maker in writing of
its inability to pay its debts as they mature; or

            (f) The filing of an involuntary petition against. Maker seeking
reorganization, arrangement or readjustment of its debts or for any other relief
under the Bankruptcy Code, as amended, or under any other insolvency act or law,
state or federal, now or hereafter existing, or the involuntary appointment of a
receiver or trustee of Maker for all or a substantial part of its property or
assets, or the issuance of a warrant of attachment or execution of similar
process against a substantial part of the property of Maker and the continuance
of such for thirty (30) days undismissed or undischarged.

      From and after an Event of Default and during the continuation thereof,
and upon demand for repayment of this Note, the principal balance due hereunder
shall bear interest at a rate equal to two and one half percent (2 1/2%) per
annum in excess of the rate of interest otherwise set out herein.

      From and after the occurrence of an Event of Default and during the
continuation thereof, Holder may, at its option, without any notice or demand
whatsoever, declare all obligations of Maker to Holder, including all
indebtedness evidenced by this Note, to be due and payable immediately and
Holder may proceed to collect such obligations forthwith including exercising
all of Holder's rights under the Standby Letter of Credit, plus all costs of
collection, including reasonable attorneys' fees if collected by and through an
attorney. It is further agreed that failure of Holder to exercise this option or
indulgence granted from time to time shall in no event be considered a waiver of
such option or estop Holder from exercising such option.

      MAKER, ITS SUCCESSORS OR ASSIGNS, AND ALL OTHER PERSONS LIABLE FOR THE
PAYMENT OF THIS NOTE, WAIVE PRESENTMENT FOR PAYMENT, DEMAND, PROTEST, AND NOTICE
OF DEMAND, DISHONOR, PROTEST, AND NONPAYMENT, AND CONSENT TO ANY AND ALL
RENEWALS, EXTENSIONS OR MODIFICATIONS THAT MIGHT BE MADE BY HOLDER AS TO THE
TIME OF PAYMENT OF THIS NOTE FROM TIME TO TIME.

      This Note is hereby expressly limited so that in no contingency or event
whatsoever shall the amount paid or agreed to be paid to Holder for the use,
forbearance or detention of the money advanced or to be advanced hereunder
exceed the highest lawful rate permissible under applicable law. If, from any
circumstances whatsoever, fulfillment of any provision hereof or of any other
agreement evidencing or securing the indebtedness, at the time performance of
such provision occurs, shall involve payment of interest in excess of that
authorized by law, the obligation to be fulfilled shall be reduced to the limit
so authorized by law, and if, from any circumstances, Holder shall ever receive
as interest an amount which would exceed the highest lawful rate applicable to
Borrower, such amount which would be excessive interest shall be applied to the
reduction of the unpaid principal balance of the indebtedness evidenced hereby
and not to the payment of interest.

      Holder shall not be deemed to waive any of its rights unless such waiver
be in writing and signed by Holder. No delay or omission by Holder in exercising
any of its rights shall operate as a waiver of such rights and a waiver in
writing on one occasion shall not be construed as a consent to a waiver of any
right or remedy on any future occasion.

      The word "Holder" as used herein shall include successors and registered
assigns of Holder, and all rights of Holder hereunder shall inure to the benefit
of its successors and registered assigns. All obligations of Maker shall bind
its transferees, successors, heirs, personal representatives and assigns.

RECITALS:

A.    By Letter of Offer and Term Sheet (collectively, the "1989 Term Sheet")
      dated October 31, 1989, The Toronto-Dominion Bank ("TD") established
      certain term and operating facilities in favour of Courtice on and subject
      to the terms and conditions set out in the 1989 Term Sheet;

B.    Each of Courtice and MRM subsequently requested TD to provide Courtice and
      MRM with certain additional financing relating to the purchase by Courtice
      of preference shares in the capital of MRM Holdings and in connection with
      the acquisition by MRM of the MRM Steel and the Mandak Metal divisions of
      The Canam Manac Group Inc.;
<PAGE>
                                     - 2 -


C.    TD agreed to provide such financing on and subject to the terms and
      conditions set out in a Letter of Offer and Term Sheet (the "1995 Term
      Sheet") dated June 19, 1995 between the TD and Courtice;

D.    Courtice, MRM, MRM Holdings, Gerdau Steel and TD amended the terms and
      conditions of the Original Facilities referred to and defined in the 1989
      Term Sheet and incorporated them, as amended, into an amended and restated
      loan agreement dated June 23, 1995 (the "Original Amended and Restated
      Loan Agreement" which expression includes the first amending agreement
      thereto dated as of September 26, 1995) which also sets out the terms and
      conditions relating to the Revolver Facility (as it then was) and the term
      facility established under the 1995 Term Sheet;

E.    On or about September 27, 1995 MRM arranged for Tellib to lend to MRM U.S.
      $38,000,000 (the "Tellib Advance") on the basis that the repayment of such
      Tellib Advance and payment of interest thereon would be postponed in
      favour of TD in form and substance satisfactory to TD;

F.    Each Gerdau Canada Group Member subsequently requested TD to provide or
      arrange for additional credit facilities in the aggregate amount of Cdn.
      $35,000,000, reconstitute the Revolver Facility and the 1995 Term
      Facility, allow MRM to borrow U.S. $38,000,000 under such reconstituted
      facilities and permit MRM to repay the Tellib Advance (partly or wholly
      funded) from the proceeds of that borrowing;

G.    By letter of offer (the "Syndication Offer") dated September 25, 1996 TD
      agreed to arrange the credit facilities requested by the Gerdau Canada
      Group referred to above;

H.    The parties thereto amended the terms and conditions of the Original
      Amended and Restated Loan Agreement and incorporated them, as amended,
      into an agreement dated as of November 8, 1996 (the "First Syndicated
      Amended and Restated Loan Agreement") which also set out the terms and
      conditions relating to the reconstituted facilities established pursuant
      to the Syndication Offer;

I.    The Borrowers at that time (the "Prior Borrowers") and Guarantors at that
      time requested the Lenders at that time (the "Prior Lenders"), and the
      Prior Lenders agreed, to amend and restate the terms and conditions of the

      the parties to the First Syndicated Amended and Restated Loan Agreement
      entered into an agreement dated as of December 18, 1998 (the "Prior Loan
      Agreement").

J.    Pursuant to the Prior Loan Agreement the Prior Lenders agreed to make
      loans and other credit available to the Prior Borrowers in the aggregate
      amount of up to Cdn.$85,000,000 under the Revolver Facility (as defined

K.    Pursuant to a loan transfer agreement dated September 27, 1999, the
      Lenders party to this Agreement became the only lenders under the Prior
      Loan Agreement entitled to be paid the entirety of the Advances (as
      defined in the Prior Loan Agreement) payable under the Prior Loan
      Agreement.

L.    The Prior Borrowers requested the Lenders to reallocate the amounts
      available under the then existing Revolver Facility and Term Facility
      (each as defined in the Prior Loan Agreement) by reducing the Revolver
      Facility to Cdn.$75,000,000 and increasing the Term Facility to
      Cdn.$200,000,000 and allow Gerdau Steel to become a Borrower. The increase
      in the existing Credit Facilities (as defined in the Prior Loan Agreement)
      was requested by the Prior Borrowers and Gerdau Steel to permit them to
      finance the acquisition of 176 issued and outstanding shares of common
      stock in FLS Holdings, Inc. (representing 88% of all such issued and
      outstanding common stock), which in turn owns 9,000,000 issued and
      outstanding shares of common stock in AmeriSteel Corporation (representing
      approximately 85% of all such issued and outstanding common stock).

M.    In response to the request from the Prior Borrowers and Gerdau Steel, the
      Lenders amended and restated the terms and conditions of the Prior Loan
      Agreement to provide the Credit Facilities outlined in more detail in the
      existing Amended and Restated Loan Agreement dated as of September 27,
      1999 (the "Existing Loan Agreement").

N.    The parties have agreed to certain minor modifications to the Existing
      Loan Agreement so that it reads in its entirety in the form of this
      Agreement.

omission in such instructions or in the performance thereof except in the case
of gross negligence or willful misconduct by the Agent.

                                REVOLVER FACILITY

2.1. Establishment of Revolver Facility

        2.1.1.    The Lenders severally confirm, on the terms and conditions set
                  out herein, the establishment of a revolving credit facility
                  (the "Revolver Facility") in favour of the Borrowers in the
                  amount equal to the lesser of (a) the Borrowing Base or (b)
                  the Revolver Amount, to be used by each Borrower to finance in
                  part the indirect acquisition of the Target Shares, as well as
                  for other general corporate purposes of the Gerdau Canada
                  Group. Each Lender agrees to participate in each Drawdown,
                  Conversion and Rollover under the Revolver Facility in
                  accordance with its Rateable Share. However, except for
                  temporary excesses arising from the Agent's allocation of
                  Bankers' Acceptances comprised in any issue of Bankers'
                  Acceptances made in accordance with Section 13.20.1, the
                  aggregate Outstanding Amount of a Lender's participation in
                  all Advances under the Revolver Facility shall not exceed its
                  Revolver Commitment.

        2.1.2.    The Revolver Facility is available, at the option of a
                  Borrower, by way of: (i) Prime Rate Loans in Canadian dollars;
                  (ii) Bankers' Acceptances in Canadian dollars; (iii) Base Rate
                  Loans in U.S. dollars; (iv) LIBOR Loans in U.S. dollars; and
                  (v) subject to the provisions of Section 7.6, Standby Credits
                  in Canadian dollars or U.S. dollars.

        2.1.3.    On the Term Drawdown Date, (i) the Revolver Facility will be
                  treated as having been drawn by the Relevant Borrower by way
                  of all Advances outstanding under the Revolver Facility (as
                  referred to and defined in the Prior Loan Agreement) and (ii)
                  each such Advance shall be treated as an Advance made by the
                  Lenders to the Relevant Borrower under this Agreement, of the
                  same Type and tenor, under the Revolver Facility.

        2.1.4     Following receipt of a Borrowing Base Report, the Majority
                  Lenders may disallow any particular receivable or inventory
                  included in the calculation of the Borrowing Base, which in
                  the credit judgment of the Majority Lenders, does not qualify
                  as an Eligible Receivable or Eligible Inventory and the
                  Borrowing Base shall be adjusted accordingly. If the Borrowing
                  Base (whether by reason of any such adjustment or otherwise)
                  is less than the Outstanding Amount of all Advances under the
                  Revolver Facility, the Borrowers shall immediately pay to the
                  Lenders an amount (or the Equivalent Amount in Canadian
                  Dollars) which is greater than or equal to such excess to be
                  applied by the Lenders in the manner stipulated in Section
                  2.5.2.

2.2. Availability and Revolving Nature of Revolver Facility

            During the Availability Period, a Borrower may borrow, repay and
reborrow Advances under the Revolver Facility on a revolving basis, subject to
the terms and conditions set out herein; provided that Gerdau Steel shall ensure
that the aggregate Outstanding Amount of all Advances under the Revolver
Facility does not exceed the Revolver Amount at any time and the aggregate
Outstanding Amount of all outstanding Standby Credits does not exceed Cdn.
$4,000,000.

2.3. Interest and Acceptance Fees on Advances under the Revolver Facility

            Interest on Prime Rate Loans shall be payable in Canadian dollars on
each Interest Payment Date applicable thereto on the outstanding principal
amount of all Prime Rate Loans made under the Revolver Facility at a rate per
annum equal to the Prime Rate in effect from time to time plus the Applicable
Margin. Acceptance Fees shall be payable in Canadian dollars on the relevant
Borrowing Date based on the face amount of the Bankers' Acceptance issued under
the Revolver Facility at a rate per annum equal to the Applicable Margin.
Interest on Base Rate Loans shall be payable in U.S. dollars on each Interest
Payment Date applicable thereto on the outstanding principal amount of all Base
Rate Loans made under the Revolver Facility at a rate per annum equal to the
Base Rate plus the Applicable Margin. Interest on LIBOR Loans shall be payable
in U.S. dollars on each Interest Payment Date applicable thereto on each LIBOR
Loan made under the Revolver Facility at a rate per annum equal to the LIBO Rate
for each applicable Interest Period plus the Applicable Margin.

2.4. Repayment under Revolver Facility

            Subject to Section 12.2, all Advances remaining outstanding under
the Revolver Facility are due and payable on the Due Date of the Revolver
Facility, together with all interest and other amounts accrued and unpaid
thereon.

2.5. Mandatory Repayment

        2.5.1.    In the event the Outstanding Amount of all Advances
                  outstanding under the Revolver Facility at any time exceeds
                  the lesser of (i) the Revolver Amount or (ii) the Borrowing
                  Base, (the "Facility Limit"), the Borrowers, without the Agent
                  being required to make demand therefor, shall forthwith make
                  the necessary payments or repayments to the Lenders to reduce
                  the Outstanding Amount of the Advances outstanding under the
                  Revolver Facility to an amount equal to or less than the
                  Facility Limit.

                                     - 41 -


        2.5.2.    On the date of each reduction of each Lender's Revolver
                  Commitment pursuant to Section 2.7, each Borrower shall repay
                  to such Lender such amount on account of such Lender's
                  Rateable Share of Advances made to such Borrower under the
                  Revolver Facility as may be required to ensure that the
                  Outstanding Amount of such Lender's Rateable Share of all
                  Advances under the Revolver Facility does not exceed its
                  Revolver Commitment at that time after giving effect to that
                  reduction. Such Lender shall apply any such amount so repaid
                  as follows:

                  (a)   first, to repay its Rateable Share of Loans under the
                        Revolver Facility;

                  (b)   second, to prepay to the Lender the obligations of each
                        Relevant Borrower under Section 7.5.9 in respect of
                        Bankers' Acceptances issued for such Borrower's account
                        under the Revolver Facility; and

                  (c)   third, to be credited to the Cash Collateral Account and
                        held as cash collateral by the Agent to secure the
                        payment and performance of the Relevant Borrower's
                        obligations under Section 7.6 in respect of outstanding
                        Standby Credits until such Standby Credits expire or are
                        drawn upon, whereupon the amounts so credited will be
                        applied by the Agent to pay such obligations in respect
                        of such drawing or (if not so required by the Majority
                        Lenders), subject to Section 12.2, returned to the
                        Relevant Borrower.

2.6. Annual Review

            Provided that no Event of Default shall have occurred and be
continuing, Gerdau Steel may, by notice in writing to the Agent given no more
than 60 days but no less than 30 days before the then effective Due Date for the
Revolver Facility (the "Current Maturity Date"), request an extension of the
Current Maturity Date by a period of 364 days. Promptly upon receipt of an
Extension Request the Agent shall notify each Lender and shall request each
Lender to approve the Extension Request within 30 days. Each Lender may, within
30 days from the date of receipt of such notice from the Agent, notify the Agent
in writing of its election to extend or not extend the Current Maturity Date as
requested by the Borrowers, which election shall be in the sole and absolute
discretion of each Lender. If a Lender agrees to an extension of the Current
Maturity Date requested by the Borrowers, the Revolver Facility Due Date shall
automatically and without any further action by any Person be extended by a
period of 364 days for that Lender, except in the circumstances described below.
If, within such 30 days a Lender does not approve in writing the extension of
the Current Maturity Date (a "Non-Extending Lender"), the Revolver Facility Due
Date shall not be so extended for that Lender, but shall remain as the Current
Maturity Date then in effect for that Lender. Any other Lender or new Lender
selected by the Borrowers (in consultation with the Agent) may, subject to
Section 14.5, take up the Revolver Commitment of a Non-Extending Lender
effective from the Current Maturity Date. Notwithstanding the foregoing, if in
relation to any extension request less than the Majority
<PAGE>
                                     - 42 -


Lenders agree to extend the Revolver Facility Due Date, then the then Current
Maturity Date for all Lenders shall not be extended, but shall remain as the
Revolver Facility Due Date then in effect. For greater certainty, the Borrowers
may request extensions under this Section every 364 days from the Current
Maturity Date.

2.7. Prepayment and Cancellation of Revolver Facility

        2.7.1.    Prepayment. Subject to the terms and conditions of this
                  Agreement, each Borrower may from time to time by giving not
                  less than three Banking Days express written notice to the
                  Agent, prepay Advances (other than Bankers' Acceptances and
                  Standby Credits) outstanding under the Revolver Facility,
                  without penalty, except that LIBOR Loans may not be prepaid
                  prior to the end of their applicable Interest Periods unless
                  the Borrower compensates the Lenders in accordance with
                  Section 8.3.

        2.7.2.    Cancellation. Gerdau Steel shall have the right at any time
                  and from time to time to cancel all or any portion of the
                  Revolver Commitment. Such right may only be exercised by
                  Gerdau Steel delivering a notice to the Agent specifying the
                  proposed effective date of such cancellation (which must be no
                  less than 30 days thereafter) and the amount of the Total
                  Revolver Commitment to be cancelled (which must be in a
                  principal amount of Cdn.$5,000,000 or a multiple of
                  Cdn.$1,000,000 in excess thereof. The Revolver Commitment
                  shall be permanently reduced on the effective date of each
                  such cancellation in the amount so cancelled.

2.8. Minimum Advance

            Unless the Agent otherwise agrees, an Advance (or any portion
thereof) by way of Prime Rate Loan under the Revolver Facility (other than any
Swing Line Advance) shall be for a minimum principal amount of Cdn.$5,000,000 or
a higher principal amount which is a whole number multiple of Cdn.$1,000,000. An
Advance (or any portion thereof) by way of an issue of Bankers' Acceptances
under the Revolver Facility shall be in a minimum aggregate face amount (subject
to availability) of Cdn. $5,000,000 and in whole number multiples of
Cdn.$1,000,000. An Advance (or any portion thereof) by way of Base Rate Loan
(other than any Swing Line Advance) or LIBOR Loan shall be in a minimum
principal amount (subject to availability) of U.S.$5,000,000. Each Advance under
the Revolver Facility (other than any Swing Line Advance) will be made pursuant
to a notice received from a Borrower complying with the provisions of Section
7.4.

2.9. Swing Line Advances

        2.9.1.  Commitment. The Swing Line Lender establishes a committed
                revolving operating credit facility in favour of the Borrowers
                to finance the day-to-day working capital requirement for the
                Borrowers and other Gerdau Canada Group Members arising in the
                ordinary course of their operations, as well as for other
                general corporate purposes of the Gerdau Canada Group. Each
                Borrower shall so apply all amounts borrowed by it under the
                Swing Line Facility.

        2.9.2.  Overdrafts. Each Advance (other than a Standby Credit) under the
                Swing Line shall be made by the Swing Line Lender on an
                overdraft basis by debiting the Canadian dollar or U.S. dollar
                Designated Account of the Relevant Borrower. The amount of such
                overdraft from time to time shall be deemed to be a Prime Rate
                Loan (to the extent of the debit balance in the Canadian dollar
                Designated Account) and a Base Rate Loan (to the extent of the
                debit balance in the U.S. dollar Designated Account). The
                Borrowers shall ensure that the aggregate Outstanding Amount of
                all outstanding Advances made by the Swing Line Lender under
                this Section does not exceed the Swing Line Amount at any time.

        2.9.3.  Standby Credit Disbursements. Upon making any Standby Credit
                Disbursement, the Swing Line Lender will promptly notify the
                Agent and the Relevant Borrower of the Swing Line Loan resulting
                from that payment pursuant to Section 7.6.4.2;

        2.9.4.  Relationship to Revolver Commitment. Except as otherwise
                provided in Section 13.26, for the purposes of each other
                Section of this Agreement, the amount of the Revolver Commitment
                of the Swing Line Lender and the Total Revolver Commitment shall
                be reduced by the Swing Line Amount and the Rateable Shares of
                the Lenders in each Borrowing made under the Revolver Facility
                (excluding the Swing Line) shall be adjusted proportionately.

        2.9.5.  Reduction of Swing Line Amount. If the Revolver Commitment of
                the Swing Line Lender determined in accordance with Subsection
                2.9.4 is reduced to nil, each further reduction of the Revolver
                Commitment of the Swing Line Lender determined without regard
                for Section 2.9.4 will reduce the Swing Line Amount by the
                amount of such reduction.

        2.9.6.  Transitional Provision: On the Term Drawdown Date, (i) the Swing
                Line will be treated as having been drawn by the Relevant
                Borrower by each outstanding Swing Line Loan (as referred to and
                defined in the Prior Loan Agreement) and (ii) each Swing Line
                Loan shall be treated as a Swing Line Advance made by the Swing
                Line Lender to the Relevant Borrower of the same Type and tenor
                under this Agreement.

2.10. Advances

            Any Advance from the Lenders requested by a Borrower in accordance
with Section 2.8 will, subject to the terms and conditions herein, be made by
the Lenders pursuant to this Section 2.10 and shall be made up of any
combination of any of the following Advances:

        2.10.1. by way of Prime Rate Loans, each in a minimum principal amount
                of Cdn.$5,000,000;

        2.10.2. by way of Bankers' Acceptances, each issue in a minimum
                aggregate face amount (subject to availability) of
                Cdn.$5,000,000;

        2.10.3. by way of Base Rate Loans, each in a minimum principal amount of
                U.S.$5,000,000; and

        2.10.4. by way of LIBOR Loans, each in a minimum principal amount
                (subject to availability) of U.S.$5,000,000.

                                   ARTICLE 3.
                                  TERM FACILITY

3.1. Establishment of Term Facility

        3.1.1.  The Lenders severally confirm, on the terms and conditions set
                out herein, the establishment of a non-revolving term credit
                facility (the "Term Facility") in favour of the Borrowers in the
                amount of the Maximum Term Amount to be used by each Borrower to
                finance in part the acquisition of the Target Shares. Each
                Lender agrees to participate in each Drawdown, Conversion and
                Rollover under the Term Facility in accordance with its Rateable
                Share. However, except for temporary excesses arising from the
                Agent's allocation of Bankers' Acceptances comprised in any
                issue of Bankers' Acceptances made in accordance with Section
                13.20.1, the aggregate Outstanding Amount of a Lender's
                participation in all Advances under the Term Facility shall not
                exceed its Term Commitment.

        3.1.2.  The Term Facility is available, at the option of a Borrower, by
                way of: (i) Prime Rate Loans in Canadian dollars; (ii) Bankers'
                Acceptances in Canadian dollars; (iii) Base Rate Loans in U.S.
                dollars and (iv) LIBOR Loans in U.S. dollars.

        3.1.3.  On the Term Drawdown Date, (i) the Term Facility will be treated
                as having been drawn by the Relevant Borrower by way of all
                Advances outstanding under the Term Facility (as referred to and
                defined in the Prior Loan Agreement) and (ii) each such Advance
                shall be treated as an Advance made by the Lenders to the
<PAGE>
                                      -45-


                Relevant Borrower under this Agreement of the same Type and
                tenor under the Term Facility.

3.2. Availability and Non-Revolving Nature of Term Facility

            Each Borrower may, subject to the terms and conditions of this
Agreement, borrow Advances under the Term Facility on the Term Drawdown Date on
a non-revolving basis having an initial Outstanding Amount which, when added to
the Outstanding Amount of all other Advances referred to in Section 3.1.3, does
not exceed the Maximum Term Amount. Any part of an Advance under the Term
Facility which is repaid may not be reborrowed and (other than any such
repayment pursuant to Section 7.9) shall constitute a permanent reduction of the
Term Facility. Each such repayment shall, to the extent thereof, reduce the Term
Commitments of the Lenders pro rata.

3.3. Repayment of Term Facility

            Subject to Section 12.2, all Loans outstanding under the Term
Facility shall be repaid by the Borrowers making the following instalment
payments to the Agent for the account of the Lenders:

        3.3.1.  Reductions. The Total Term Commitment shall permanently reduce
                at the end of the Term Drawdown Date by the amount, if any, by
                which the Total Term Commitment exceeds the Outstanding Amount
                of all Advances outstanding under the Term Facility on such
                date. The Borrowers shall not be entitled to any further
                Drawdowns under the Term Facility after the Term Drawdown Date.

        3.3.2.  Scheduled Instalments. Subject to Section 12.2, the Borrowers
                shall repay all Advances outstanding under the Term Facility in
                consecutive semi-annual instalments on each day falling 12, 18,
                24, 30, 36, 42, 48, 54 and 60 months after the Term Drawdown
                Date in the following Outstanding Amounts (and the Total Term
                Commitment shall permanently reduce on each such date by each
                such amount):

        3.3.3.  Free Cash Flow Reductions. On the 30th Banking Day falling after
                the day Gerdau Steel delivers the audited annual financial
                statements of Gerdau Steel to the Agent for each Fiscal Year
                starting with the 2000 Fiscal Year pursuant to Section
                11.1.1.10.1, the Relevant Borrowers with Advances under the Term
                Facility shall repay Advances in the Outstanding Amount equal to
                (i) seventy-five percent (75%) of Free Cash Flow if such Fiscal
                Year is the 2000 Fiscal Year and (ii) fifty percent (50%) of
                Free Cash Flow if such Fiscal Year is after the 2000 Fiscal
                Year, and the Total Term Commitment shall be permanently reduced
                on such date in like amount.

        3.3.4.  Capital Asset Dispositions. The Total Term Commitment shall
                permanently reduce on each day on which any Gerdau Canada Group
                Member disposes of any capital assets having a book value
                exceeding Cdn.$5,000,000 by an amount equal to the Net Asset
                Disposal Proceeds of such disposal. If Gerdau Canada Group
                disposes of capital assets having an aggregate book value
                exceeding Cdn.$5,000,000 during any period of four consecutive
                Fiscal Quarters, then on the thirtieth day after the end of the
                last Fiscal Quarter in such period, the Total Term Commitment
                shall permanently reduce by the amount, if any, by which Net
                Asset Disposition Proceeds derived from such disposals exceeds
                the aggregate amount, if any, of each prior reduction to the
                Total Term Commitment made pursuant to this Section 3.3.4 in
                respect of capital asset disposals made during such four
                consecutive Fiscal Quarter period. The Borrowers shall promptly
                notify the Agent of full particulars pertaining to any capital
                asset disposal contemplated by this Section 3.3.4 and of any
                required repayment under this Section 3.3.4.

        3.3.5.  Indebtedness Reductions. The Total Term Commitment shall
                permanently reduce on each day on which any Gerdau Canada Group
                Member incurs new Indebtedness, other than Indebtedness referred
                to in clause (x) of the definition of "Permitted Liens" and
                other than Indebtedness to any Person that is either Gerdau S.A.
                or another Gerdau Canada Group Member, by an amount equal to the
                sum of
<PAGE>
                                      -47-


                all cash and Cash Equivalent Investments received from such
                Indebtedness net of all costs and expenses incurred in effecting
                such Indebtedness, including legal expenses and underwriting
                fees and commissions payable to any Person that is not a Gerdau
                Canada Group Member or an Affiliate.

        3.3.6.  Rights Offering Reductions. The Total Term Commitment shall
                permanently reduce on each day on which any Gerdau Canada Group
                Member issues Capital Stock, or any rights to acquire Capital
                Stock, (a "Rights Offering") to any Person that is not either
                Gerdau S.A. or another Gerdau Canada Group Member by an amount
                equal to the sum of all cash and Cash Equivalent Investments
                received from such Rights Offering net of all costs and expenses
                incurred in effecting such Rights Offering, including legal
                expenses and underwriting fees and commissions payable to any
                Person that is not a Gerdau Canada Group Member or an Affiliate.

        3.3.7.  Voluntary Reductions. The Borrowers shall have the right at any
                time and from time to time to prepay and permanently cancel,
                without premium or penalty, all or any portion of the Total Term
                Commitment. Such right may only be exercised by Gerdau Steel
                delivering a notice to the Agent specifying the proposed
                effective date of prepayment and cancellation (which must be no
                less than three Banking Days thereafter) and the amount of the
                Total Term Commitment to be cancelled (which must be in a
                principal amount of Cdn.$5,000,000 or a multiple of
                Cdn.$1,000,000 in excess thereof). The Total Term Commitment
                shall be permanently reduced on the effective date of each such
                cancellation in the amount so cancelled.

        3.3.8.  Prepayment of Affected Lenders. Gerdau Steel shall have the
                right to permanently cancel without premium or penalty all, but
                not part, of the Revolver Commitment and Term Commitment of each
                Affected Lender provided that no Default or Event of Default has
                occurred. Such right may only be exercised by Gerdau Steel
                delivering a notice to the Agent advising of such cancellation
                and specifying the effective date of cancellation which must be
                no less than five Banking Days after and no later than 30 days
                after the relevant Lender became an Affected Lender. Each
                Relevant Borrower shall prepay the Affected Lender's Rateable
                Share of all outstanding Advances on such effective date of
                cancellation and such Affected Lender shall be released from its
                obligations to lend hereunder.

        3.3.9.  Mandatory Prepayments. On the date of each reduction of each
                Lender's Term Commitment pursuant to the foregoing provisions of
                this Article 3, each Borrower shall repay to each Lender such
                amount on account of such Lender's Rateable Share of Advances
                made to such Borrower under the Term Facility as may be required
                to ensure that the Outstanding Amount of such Lender's Rateable
                Share of all Advances under the Term Facility does not exceed
                its Term Commitment at that time after giving effect to that
                reduction. Such Lender shall apply any such amount so repaid as
                follows:
<PAGE>
                                      -48-


        (a)     first, to repay its Rateable Share of Loans under the Term
                Facility; and

        (b)     second, to prepay to the Lender the obligations of each Relevant
                Borrower under Section 7.5.9 in respect of Bankers' Acceptances
                issued for such Borrower's account under the Term Facility.

3.4. Interest and Acceptance Fees on Advances under the Term Facility

            Interest on Prime Rate Loans shall be payable in Canadian dollars on
each Interest Payment Date applicable thereto on the outstanding principal
amount of all Prime Rate Loans made under the Term Facility at a rate per annum
equal to the Prime Rate in effect from time to time plus the Applicable Margin.
Acceptance Fees shall be payable in Canadian dollars on the relevant Borrowing
Date based on the face amount of Bankers' Acceptances under the Term Facility at
a rate per annum equal to the Applicable Margin. Interest on Base Rate Loans
shall be payable in U.S. dollars on each Interest Payment Date applicable
thereto on the outstanding principal amount of all Base Rate Loans made under
the Term Facility at a rate per annum equal to the Base Rate plus the Applicable
Margin. Interest on LIBOR Loans shall be payable in U.S. dollars on each
Interest Payment Date applicable thereto on the outstanding principal amount of
each LIBOR Loan made under the Term Facility at a rate per annum equal to the
LIBO Rate for each applicable Interest Period plus the Applicable Margin.

3.5. Prepayment of Term Facility

            Subject to the terms and conditions of this Agreement, each Borrower
may from time to time by giving not less than three Banking Days express written
notice to the Agent, prepay Prime Rate Loans and Base Rate Loans (but not
Bankers' Acceptances) outstanding under the Term Facility, without penalty or
prepay LIBOR Loans outstanding under the Term Facility, except that LIBOR Loans
may not be prepaid prior to the end of their respective Interest Periods unless
the Borrower compensates the Lenders in accordance with Section 8.3.

3.6. Minimum Advance

            Each Advance under the Term Facility shall be for a minimum
aggregate amount of $10,000,000 (Canadian or U.S., as applicable) made up of any
combination of the following Advances:

        3.6.1.  by way of Prime Rate Loans, each in a minimum principal amount
                of Cdn.$5,000,000;
<PAGE>
                                      -49-


        3.6.2.  by way of Bankers' Acceptances, each issue in a minimum
                aggregate face amount (subject to availability) of
                Cdn.$5,000,000 and in whole number multiples of Cdn. $100,000;

        3.6.3.  by way of Base Rate Loans, each in a minimum principal amount of
                U.S.$5,000,000; and

        3.6.4.  by way of LIBOR Loans, each in a minimum principal amount
                (subject to availability) of U.S.$10,000,000.

3.7. Consolidation of Loans

            If for any reason (including payments and prepayments) the principal
or aggregate face amount of any Advance made pursuant to the Term Facility falls
below the minimum prescribed in Section 3.6 (a "Small Term Loan"), the Borrowers
will cooperate with the Agent in consolidating such Small Term Loan with such
other Advance under the Term Facility as the Agent may designate to form one
Advance having an aggregate principal or face amount satisfying the requirements
for Advances imposed under Section 3.6. Alternatively, the Relevant Borrower
will immediately prepay Small Term Loans pursuant to Section 3.5.

                               HEDGING FACILITIES

4.1. Prior Hedging Facility

        4.1.1.  TD has established a discretionary hedging facility in favour of
                the Borrowers to be used by each Borrower for hedging its
                interest rate and Currency exposures on Advances under the
                Credit Facilities and for foreign exchange contracts, and for
                any other purpose permitted under this Agreement. TD is the only
                Hedging Lender as at the date of this Agreement.

        4.1.2.  Any other Lender may establish a discretionary hedging facility
                in favour of the Borrowers to be used by each Borrower for
                hedging its interest rate and Currency exposures on Advances
                under the Credit Facilities and for foreign exchange contracts,
                and for any other purpose permitted under this Agreement. Upon
                such establishment, the Lender concerned shall forthwith notify
                the Agent, whereupon it will become a Hedging Lender for the
                purposes of this Agreement.

        4.1.3.  Each Hedging Instrument entered into between a Borrower and a
                Hedging Lender for a purpose permitted under this Agreement is
                referred to in this Agreement as an "Eligible Hedging
                Instrument".
<PAGE>
                                      -50-


        4.1.4.  Each Hedging Instrument must be governed by a master netting
                agreement in the form published by the International Swaps and
                Derivatives Association, Inc. under which the Full Two Way
                Payments (as referred to and defined therein) method of
                termination applies, or in such other form as the Agent may
                approve (a "Master ISDA Agreement").

        4.1.5.  As at the Term Drawdown, each Hedging Lender and Eligible
                Hedging Instrument under the Prior Loan Agreement shall be
                considered as a Hedging Lender and Eligible Hedging Instrument
                under this Agreement.

                                   ARTICLE 5.
                                     PAYMENT

5.1. Place of Payment

            All funds made available by the Lenders pursuant to the Credit
Facilities shall be made or delivered to the Agent at the Agent's Branch of
Account and then, subject to Sections 7.5.7 and 13.20, transferred to the
relevant Designated Account. All payments of principal, interest and fees or
other amounts payable by each Borrower to the Lenders hereunder shall be made or
delivered to the Agent at the Agent's Branch of Account and then transferred to
each Lender's Lending Office in accordance with each Lender's Rateable Share.
All payments of principal, interest and fees or other amounts payable by each
Borrower to the Swing Line Lender shall be made or delivered to the Swing Line
Lender at its Branch of Account.

5.2. Application of Payments and Prepayments

            Before any Default or Event of Default occurs, the Agent shall
appropriate and apply each payment made by a Borrower under this Agreement in
and towards payment of such Loan Obligations as such Borrower shall designate to
the Agent at the time of such payment or, failing such designation, in and
towards such indebtedness or Loan Obligations of such Borrower as the Agent
shall designate. After a Default or an Event of Default occurs, the Agent shall
be entitled, subject to Article 13, to appropriate and apply each payment made
by each Borrower under this Agreement in and towards payment of such
indebtedness or Loan Obligations of a Borrower as the Agent shall designate,
notwithstanding any designation made by a Borrower. Any amount of the Term
Facility repaid pursuant to Section 3.3 or prepaid pursuant to Section 3.5
shall, to the extent thereof, satisfy the Borrower's repayment obligations under
Section 3.3.2 in inverse order of maturity.

5.3. Change in Circumstances

           If the introduction of or any Change in Law:

        5.3.1.  subjects any Lender (or its Holding Body Corporate) to, or
                causes the withdrawal or termination of a previously granted
                exemption with respect to, any Taxes or changes the basis of
                taxation of payments on any Lender (or its Holding Body
                Corporate) due to the Lenders (or its Holding Body Corporate) or
                increases any existing Taxes on payments of the Loan Obligations
                (other than the Lender's Own Taxes (or those of its Holding Body
                Corporate));

        5.3.2.  imposes, modifies or deems applicable reserve, liquidity, cash,
                margin, capital, special deposit, deposit insurance or
                assessment, or any other regulatory or similar requirement
                against assets held by, or deposits in or for the account of, or
                loans by, or any other acquisition of funds for loans by, any
                Lender (or those of its Holding Body Corporate), or any
                unutilized portion of any Credit Facility or any obligations of
                any Lender under any Loan Document;

        5.3.3.  imposes on any Lender (or its Holding Body Corporate) any Taxes
                on reserves or deemed reserves in respect of the undrawn portion
                of any Credit Facility;

        5.3.4.  imposes on any Lender (or its Holding Body Corporate) or
                requires there to be maintained by any Lender (or its Holding
                Body Corporate) any capital adequacy or additional capital
                requirement (including a requirement which affects the Lenders'
                (or its Holding Body Corporate's) allocation of capital
                resources to its obligations) in respect of any Credit Facility,
                any Advance, any Derivative, this Agreement or the Lenders'
                obligations hereunder or imposes any other condition or
                requirement with respect to the maintenance by any Lender of a
                contingent liability with respect to any Credit Facility, any
                Advance or any Derivative hereunder; or

        5.3.5.  imposes on any Lender (or its Holding Body Corporate) any other
                condition or requirement with respect to this Agreement or a
                Credit Facility (other than the Lender's Own Taxes (or those of
                its Holding Body Corporate));

and, in the sole determination of such Lender (the "Affected Lender"), such
occurrence has the effect of:

        5.3.6.  increasing the cost to the Affected Lender (or its Holding Body
                Corporate) of the Affected Lender agreeing to make or making,
                maintaining or funding a Credit Facility, any Advance, any
                Derivative or any portion of any thereof;
<PAGE>
                                      -52-


        5.3.7.  reducing the amount of the Loan Obligations or the net income
                received by the Affected Lender in respect of this Agreement, a
                Credit Facility, any Advance, any Derivative, or any portion of
                any thereof;

        5.3.8.  directly or indirectly reducing the effective return to the
                Affected Lender (or its Holding Body Corporate) under this
                Agreement on its overall capital as a result of entering into
                this Agreement or as a result of any of the transactions or
                obligations contemplated by this Agreement (other than a
                reduction resulting from a higher rate of Income Tax being
                imposed on the Affected Lender's (or its Holding Body
                Corporate's) overall income); or

        5.3.9.  causing the Affected Lender to make any payment or to forego any
                interest, fees or other return on or calculated by reference to
                any sum received or receivable by the Affected Lender hereunder,

then, upon demand from time to time being made to the Relevant Borrowers by the
Agent on behalf of the Affected Lender, accompanied in each case by a
certificate of the Affected Lender documenting the relevant calculations of the
compensation being claimed by the Affected Lender (which certificate shall be
conclusive and binding on the parties hereto for all purposes, absent manifest
error), the Borrowers shall forthwith pay to the Agent for the account of the
Affected Lender such additional amounts as are set out in each such certificate
in order to fully compensate the Affected Lender (or its Holding Body Corporate)
for such additional cost, reduction, payment, foregone interest or other return.
The amount payable by each Borrower under this Section 5.3 shall be made in
proportion to its share of the aggregate Outstanding Amount of all outstanding
Advances under the Credit Facilities, unless the Agent otherwise agrees.

5.4. Payments Generally

            All payments to be made by a Borrower in respect of Advances (in
respect of principal, interest, fees or otherwise) shall be made by the Relevant
Borrower to the Agent for the account of the Lender or Lenders concerned or to
the Swing Line Lender (as applicable) no later than 11:00 a.m. (Toronto time) on
the due date thereof (i) to the accounts of the Agent specified therefor by the
Agent at the Agent's Branch of Account or (ii) to the Swing Line Lender by
transfer to the Designated Accounts, in each case at the applicable Branch of
Account, or, in any such case, to such other accounts as may be specified by
such Lender to the Relevant Borrower from time to time. If a payment is not made
by such time it shall be considered to have been made on the next Banking Day,
unless the Lender concerned agrees, in its sole discretion, to accept a payment
at a later time as being effective on the date it is made. All payments to be
made by a Borrower shall be made by way of certified cheque, bank draft or other
immediately available funds, freely transferable, cleared funds for value on the
due date.

5.5. Repayment Notice

            Each Relevant Borrower shall deliver a Repayment Notice to the Agent
at least five Banking Days before any required repayment is made pursuant to any
provision of this Agreement.

5.6. Netting of Payments

            If on any date amounts would be payable under this Agreement in the
same currency by the Relevant Borrower to the Lenders and by the Lenders to the
Relevant Borrower, then, on such date, upon notice from the Agent stating that
netting is to apply to such payments, each such party's obligations to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by the Relevant
Borrower to the Lenders exceeds the aggregate amount that would otherwise have
been payable by the Lenders to the Relevant Borrower or vice versa, such
obligations shall be replaced by an obligation upon the Relevant Borrower or the
Lenders by whom the larger aggregate amount would have been payable to pay to
the other the excess of the larger aggregate amount over the smaller aggregate

                                   ARTICLE 7.
                                    ADVANCES

7.1. Advance and Interest Payment Dates

            Upon timely fulfillment of and compliance with all applicable terms
and conditions as set forth in this Agreement, the Agent (to the extent it has
received funds from the Lenders) on behalf of the Lenders will make the
requested amount of any Advance by way of Prime Rate Loan, Base Rate Loan or
LIBOR Loan requested by the Relevant Borrower available to the Relevant Borrower
on the Drawdown Date by crediting its Designated Account with such amount. The
Relevant Borrower shall pay interest to the Swing Line Lender or to the Agent
for the account of the Lenders (as applicable) at such Lender's Branch of
Account on each Loan borrowed by the Relevant Borrower which is outstanding from
time to time hereunder at the rate of interest applicable to such Loan as set
out in this Agreement.

            Interest on each Prime Rate Loan, Base Rate Loan and LIBOR Loan
shall be payable on each Interest Payment Date applicable thereto. All interest
shall accrue from day to day and shall be payable in arrears for the actual
number of days elapsed from and including the Borrowing Date of such Loan or the
previous date on which interest was payable, as the case may be, to but
excluding the date on which interest is payable, or the end of the Interest
Period, as the case may be, both before and after maturity, default and
judgment, with interest on overdue interest at the same rate payable on demand.
Overdue interest with respect to a LIBOR Loan made under a Credit Facility
shall, upon the expiry of the Interest Period applicable to such LIBOR Loan,
bear interest, payable on demand, calculated at the rates and in the manner
applicable to Base Rate Loans made under the same Credit Facility.

            Interest calculated with reference to the Prime Rate or the Base
Rate shall be calculated daily and compounded monthly on the basis of a year of
365 or 366 days, as applicable. Interest calculated with reference to the LIBO
Rate shall be calculated daily and compounded at the end of the Interest Period
applicable thereto, and if the Interest Period is longer than three months,
every three months on the basis of a year of 360 days.

7.2. Payment of Interest

            Each Borrower shall pay to the Agent for the account of the
applicable Lenders interest on each Loan borrowed by it in the manner and at the
rates per annum determined in accordance with this Agreement. Interest payable
hereunder shall be payable both before and after maturity, default and/or
judgment, if any, until payment in full thereof, and interest shall accrue on
overdue interest, if any, at the same rate, except as otherwise provided in
Section 7.1. Changes in the Prime Rate or the Base Rate shall cause an immediate
adjustment of the interest payable hereunder with respect to Prime Rate Loans
and Base Rate Loans, respectively, without the necessity of any notice to the
Borrowers.

7.3. Conversions

            Subject to the other terms of this Agreement, the Relevant Borrower
may from time to time convert all or any part of the outstanding amount of any
Advance under the Term Facility (other than any Advance by way of Standby Credit
or any Swing Line Loan) on its Maturity Date (in the case of a LIBOR Loan or an
issue of Bankers' Acceptance) or at any time (in the case of Prime Rate Loan or
a Base Rate Loan) into another form of Advance denominated in the same Currency
under the Term Facility permitted by this Agreement by giving the Agent a
Conversion Notice in accordance with Section 7.4 provided that any part of an
Advance that is not converted and the resulting new Advance each comply with the
amounts specified below:

        7.3.1.  in the case of a Prime Rate Loan or Base Rate Loan, a minimum
                principal amount of $5,000,000 (Cdn. or U.S., as applicable);

        7.3.2.  in the case of a LIBOR Loan, a minimum principal amount (subject
                to availability) of U.S.$10,000,000; and

        7.3.3.  in the case of an issue of Bankers' Acceptances, a minimum
                aggregate face amount (subject to availability) of Cdn.
                $5,000,000 and in whole number multiples of Cdn. $1,000,000.

7.4. Notice of Advances, Payments, Conversions and Rollovers

            Each Borrowing Notice and Repayment Notice, as the case may be,
shall be given no later than:

        7.4.1.  on the third Banking Day prior to any Borrowing Date or payment
                date, in respect of any Prime Rate Loan or Base Rate Loan in an
                amount of $50,000,000 (Cdn. or U.S., as applicable) or more;

        7.4.2.  on the second Banking Day prior to any Borrowing Date or payment
                date, in respect of any Prime Rate Loan or Base Rate Loan in an
                amount of $10,000,000 (Cdn. or U.S., as applicable) or more but
                less than $25,000,000 (Cdn. or U.S., as applicable);

        7.4.3.  on the Banking Day before the Borrowing Date of any Prime Rate
                Loan or Base Rate Loan or payment date, in respect of any Prime
                Rate Loan or Base Rate Loan in an amount less than $10,000,000
                (Cdn. or U.S., as applicable);

        7.4.4.  on the third Banking Day prior to the Borrowing Date or payment
                date of any LIBOR Loan; and
<PAGE>
                                      -60-


        7.4.5.  on the second Banking Day prior to the Borrowing Date of any
                Bankers' Acceptances.

Notices shall be given not later than 10:00 a.m. (Toronto time) on the last
available date for notice. If a notice is not given by such time, it shall be
deemed to have been given on the next Banking Day. If a Conversion Notice is not
given by 10:00 a.m. on the second Banking Day prior to a proposed Conversion,
the Lenders may, in the case of a proposed Conversion to Bankers' Acceptances,
decline to accept such Bankers' Acceptances and in the case of a proposed
Conversion to a Prime Rate Loan, may charge, as liquidated damages, interest on
the resulting Prime Rate Loan at a rate equal to 115% of the rate of interest
otherwise applicable to such Prime Rate Loan under this Agreement for a period
of two Banking Days from the maturity of the Bankers' Acceptances. Thereafter
the rate of interest applicable to such Prime Rate Loan shall be the rate of
interest otherwise applicable to such Loan, as set out in this Agreement. The
foregoing provisions shall also apply if a Borrower requests a Rollover of
Bankers' Acceptances to take place on the Maturity Date of another issue of
Bankers' Acceptances but does not give a Rollover Notice by 10:00 a.m. on the
second Banking Day prior to such Maturity Date. The Relevant Borrower agrees
that such additional interest is a reasonable pre-estimate of loss to each
Lender and not a penalty. Such increased interest is payable for the
administrative expense incurred by each Lender and for the loss of protection
against future interest rate risks suffered by each Lender as a result of a
Borrower's failure to give any of these notices.

7.5. Bankers' Acceptances

            The following provisions shall apply to Advances obtained by way of
the issuance of Bankers' Acceptances:

        7.5.1.  all drafts required to be accepted by a Lender pursuant to this
                Agreement shall be in the form requested by such Lender, and,
                shall be executed and drawn by such Lender on behalf of the
                Relevant Borrower pursuant to the power of attorney contained in
                Section 7.5.3;

        7.5.2.  any Borrowing Notice requesting an issue of Bankers' Acceptances
                shall include instructions from the Relevant Borrower stating
                that it wishes to have drafts accepted as Bankers' Acceptances
                under this Agreement and stating the aggregate face amount of
                and the term (being, subject to availability, one, two, three or
                six months) applicable to such drafts. The Relevant Borrower may
                notify the Agent by telephone of its instructions with respect
                to Bankers' Acceptances, provided it shall immediately
                thereafter confirm its telephone instructions given pursuant to
                this paragraph by a Borrowing Notice;

        7.5.3.  each Borrower authorizes each Lender, and for this purpose
                appoints each Lender the lawful attorney of such Borrower, to
                complete, sign and endorse drafts on its

                                      -61-


                behalf in handwritten or by facsimile or mechanical signature in
                accordance with each Borrowing Notice and, once so completed,
                signed and endorsed, and following acceptance of them as a
                Bankers' Acceptance under this Agreement, then purchase,
                discount or negotiate such Bankers' Acceptances in accordance
                with the provisions of this Section 7.5. Drafts so completed,
                signed and endorsed and negotiated on behalf of each Borrower
                shall bind such Borrower as if so performed by an authorized
                officer of such Borrower;

        7.5.4.  the face amount of each Bankers' Acceptance to be accepted by a
                Lender shall be a whole number multiple of Cdn. $100,000;

        7.5.5.  the Agent shall have the discretion to restrict the term and the
                Maturity Date of an issue of Bankers' Acceptances. The Maturity
                Date of each issue of Bankers' Acceptances must be no later than
                the Due Date of the relevant Credit Facility. There shall not be
                more than ten (10) issues of Bankers' Acceptances maturing
                during any single calendar month under the Credit Facilities,
                unless the Agent otherwise agrees;

        7.5.6.  each Lender shall purchase each Bankers' Acceptance accepted by
                it at a discount to yield (excluding the Acceptance Fee) an
                interest rate per annum equal to such Lender's BA Reference Rate
                on each Acceptance Date of Bankers' Acceptances issued pursuant
                to this Agreement. The obligation of the Relevant Borrower to
                pay to a Lender the face amount of each Bankers' Acceptance so
                purchased by it upon the maturity of such Bankers' Acceptance
                shall continue in full force and effect notwithstanding such
                purchase. A Lender may at any time and from time to time hold,
                sell, rediscount or otherwise dispose of any Bankers' Acceptance
                purchased by it;

        7.5.7.  when Bankers' Acceptances are being issued, each Lender shall
                transfer to the Agent at the Agent's Branch of Account for value
                on the Acceptance Date immediately available Canadian dollars in
                an amount equal to the net proceeds of sale of all Bankers'
                Acceptances purchased by it on such Acceptance Date, net of the
                applicable Acceptance Fee in respect of such Bankers'
                Acceptances. Subject to Section 7.9, the Agent will transfer
                such amounts to the Relevant Borrower by depositing the same for
                value on the applicable Acceptance Date to the Designated
                Account of the Relevant Borrower;

        7.5.8.  the Acceptance Fee applicable to each Bankers' Acceptance shall
                be calculated upon the principal face amount of such Bankers'
                Acceptance for the duration of its term on the basis of the
                actual number of days from the date of its acceptance by a
                Lender up to the Maturity Date of the Bankers' Acceptance
                calculated on the basis of a 365 day year at the rates per annum
                provided for in Section 2.3 or 3.4, as applicable;
<PAGE>
                                      -62-


        7.5.9.  the Relevant Borrower shall provide for the payment to the
                Lenders at the Agent's Branch of Account of the full face amount
                of each issue of Bankers' Acceptance on its Maturity Date or, on
                the occurrence of an Event of Default, prior to its Maturity
                Date forthwith pursuant to Section 12.3. The Relevant Borrower
                shall not be entitled to prepay any Bankers' Acceptances. Where
                an issue of Bankers' Acceptances matures and the Relevant
                Borrower does not provide for payment or otherwise designate the
                manner in which payment is to be made in accordance with the
                provisions of this Agreement, the Borrower shall be deemed to
                have provided for payment of the aggregate face amount of such
                Bankers' Acceptances by Conversion into a Prime Rate Loan under
                the Credit Facility pursuant to which the Bankers' Acceptances
                were issued in a principal amount equal to the aggregate face
                amount of the Bankers' Acceptances on their Maturity Date;

       7.5.10.  the Relevant Borrower shall not claim from any Lender any days
                of grace for the payment at maturity of any Bankers' Acceptances
                presented and accepted by the Lender pursuant to this Agreement.
                In addition, the Relevant Borrower waives any demand,
                presentment for payment, protest, noting of protest, dishonour,
                notice of dishonour and any other notice or defence to payment
                which might otherwise exist if for any reason a Bankers'
                Acceptance is held by the Lender in its own right at the
                maturity thereof and the Relevant Borrower shall pay the Agent
                for the account of such Lender the face amount of any such
                Bankers' Acceptance on its Maturity Date;

       7.5.11.  any executed drafts to be used as Bankers' Acceptances which are
                held by the Agent or a Lender need only be held in safekeeping
                with the same degree of care as if they were such Lender's own
                property and such Lender was keeping them at the place at which
                they are to be held. Each Borrower shall, by written notice to
                the Agent, designate the Persons authorized to give the Agent
                instructions regarding the manner in which drafts are to be
                completed and the time at which they are to be issued;

       7.5.12.  the Relevant Borrower agrees to forthwith reimburse each Lender
                in full any amount paid by the Lender in respect of any Bankers'
                Acceptance accepted by the Lender hereunder on its behalf;
                however, the Relevant Borrower shall not be obliged to indemnify
                any Lender for any fees or expenses caused by the gross
                negligence or willful misconduct of such Lender;

       7.5.13.  the obligations of each Borrower under this Section 7.5 are
                unconditional, shall not be subject to any qualification or
                exception whatsoever and shall be fulfilled strictly in
                accordance with the terms of this Agreement under all
                circumstances including the following:

                7.5.13.1.  any lack of validity or enforceability of any draft
                           accepted by any Lender as a Bankers' Acceptance; or
<PAGE>
                                      -63-


                7.5.13.2.  the existence of any claim, set-off, defence or
                           otherwise which the Relevant Borrower may have at any
                           time against the holder of a Bankers' Acceptance, any
                           Lender or any other Person or entity whether in
                           connection with this Agreement or otherwise;

       7.5.14.  each Borrower shall execute and deliver such bankers'
                acceptances agreements, indemnities, directions, powers of
                attorney and other assurances as any Lender may reasonably
                require from time to time with respect to any issue of Bankers'
                Acceptances. Such documents shall take effect subject to Section
                1.11;

       7.5.15.  if any provision of this Agreement has the effect of requiring a
                Bankers' Acceptance to be prepaid, such prepayment is effected
                by paying to the Agent an amount in Canadian dollars equal to
                the face amount of such Bankers' Acceptance and the Agent paying
                the amount so received by it into an interest bearing account
                with it in the name of the Relevant Borrower from which the only
                withdrawal which may be made is to pay the Lender accepting such
                Bankers' Acceptance the face amount of such Bankers' Acceptance
                on its Maturity Date.

       7.5.16.  If a Lender is not permitted by Applicable Law, or does not by
                virtue of customary market practice, accept drafts for the
                purpose of subsequent sale as a bankers' acceptance (a
                "Non-Acceptance Lender"), each time a Relevant Borrower gives a
                Borrowing Request for an issue of Bankers' Acceptances, such
                Non-Acceptance Lender shall, in lieu of accepting and purchasing
                Bankers' Acceptances pursuant to this Section 7.5, make an
                advance in Canadian dollars to the Relevant Borrower (a "B/A
                Equivalent Advance") in the amount equal to the Acceptance
                Proceeds which would be derived from a hypothetical sale of
                drafts accepted by it ("Notional Acceptances") in the aggregate
                face amount of its Rateable Share of such requested issue of
                Bankers' Acceptances at a discount rate that yields to such
                Non-Acceptance Lender (excluding the Acceptance Fee) an interest
                rate per annum equal to such Lender's BA Reference Rate. Any B/A
                Equivalent Advance shall be repayable on the maturity of such
                issue of Bankers' Acceptances. A Non-Acceptance Lender shall be
                entitled to deduct from the amount of its B/A Equivalent Advance
                to be paid to the Agent pursuant to Section 7.5.7 an amount
                equal to the Acceptance Fee determined in accordance with
                Section 7.5.8 that would have been payable to it with respect to
                the Notional Acceptances corresponding to the B/A Equivalent
                Advance. For the purposes of this Agreement each reference to an
                issue of Bankers' Acceptances shall be deemed to include, where
                relevant, B/A Equivalent Advances, with the necessary changes
                being made to fit the context.

7.6. Standby Credits

            The following provisions apply to Advances obtained by way of
issuance of Standby Credits:

        7.6.1.  A Standby Credit may be requested by a Borrower to be issued by
                the Issuing Bank under the Swing Line in Canadian dollars or
                U.S. dollars or, with the prior consent of the Agent and the
                Issuing Bank, any other Currency;

        7.6.2.  The Issuing Bank shall have the right, in its sole discretion,
                to limit the Maturity Date of any Standby Credit. Following the
                occurrence of a Default or Event of Default, the Issuing Bank
                shall have the right, in its sole discretion, to extend the
                Maturity Date of any Standby Credit whether or not any other
                party requests or objects to such extension;

        7.6.3.  Notwithstanding any other provision of this Section 7.6, no
                Borrower may request the issuance of any Standby Credit (i) if
                the aggregate Outstanding Amount of all Standby Credits
                outstanding under the Revolver Facility would, after the
                issuance of the Standby Credit in question, exceed Cdn.
                $4,000,000; or (ii) having a term which would extend beyond the
                Revolver Facility Due Date;

        7.6.4.  Reimbursement

                7.6.4.1.   The Relevant Borrower unconditionally and irrevocably
                           authorizes the Issuing Bank to pay the amount of any
                           demand made on the Issuing Bank in accordance with
                           the terms of any Standby Credit issued for its
                           account on demand without requiring proof of the
                           Relevant Borrower's agreement that the amount so
                           demanded was due and notwithstanding that the
                           Relevant Borrower may dispute the validity of any
                           such demand or payment;

                7.6.4.2.   The Relevant Borrower shall indemnify and save the
                           Issuing Bank harmless from and against any and all
                           payments and losses and expenses (other than lost
                           profits) which it may suffer or incur arising in any
                           manner whatsoever out of the issuance of any Standby
                           Credit, including the making of, or refusal to make,
                           any payments demanded thereunder (including any court
                           costs and legal costs on a solicitor and client scale
                           incurred in connection with any proceedings to
                           restrain the Issuing Bank from making, or to compel
                           the Issuing Bank to make, any such payment). This
                           indemnity shall be unconditional, shall not be
                           subject to any qualification or exception whatsoever
                           and shall not be lessened, invalidated or otherwise
                           prejudiced for any reason whatsoever including by
                           reason of (i) any lack of validity or enforceability
                           of the Standby Credit, (ii) any claim, set-off,
                           defence or
<PAGE>
                                      -65-


                           other right the Relevant Borrower may have
                           against the beneficiary of the Standby Credit,
                           including any claim that a demand for payment under
                           the Standby Credit is fraudulent or (iii) any of the
                           matters referred to in Section 7.6.5.

        7.6.5.  Issuing Bank Not Liable

                7.6.5.1.   The Issuing Bank shall not have any responsibility or
                           liability for, or duty to inquire into, the
                           sufficiency, authorization, execution, signature,
                           endorsement, correctness, genuineness or legal effect
                           of any certificate or other document presented to it
                           pursuant to any Standby Credit and the Relevant
                           Borrower for whom such Standby Credit was issued
                           fully and unconditionally assumes all risks with
                           respect to the same and, without limiting the
                           generality of the foregoing, all risks of the acts or
                           omissions of any beneficiary of any Standby Credit
                           with respect to the use by any beneficiary of any
                           Standby Credit. The Issuing Bank shall not be
                           responsible:

                           7.6.5.1.1.   for the validity or genuineness of
                                        certificates or other documents
                                        delivered under or in connection with
                                        any Standby Credit that appear on their
                                        face to be in order, even if such
                                        certificates or other documents should
                                        in fact prove to be invalid, fraudulent
                                        or forged;

                           7.6.5.1.2.   for errors, omissions, interruptions or
                                        delays in transmission or delivery of
                                        any messages by mail, cable, telegraph,
                                        telefax, wireless or otherwise, whether
                                        or not they are in code;

                           7.6.5.1.3.   for errors in translation or for errors
                                        in interpretation of technical terms or
                                        for errors in the calculation of amounts
                                        demanded under any Standby Credit;

                           7.6.5.1.4.   for any failure or inability by the
                                        Issuing Bank or anyone else to make
                                        payment under any Standby Credit as a
                                        result of any Applicable Law or by
                                        reason of any control or restriction
                                        rightfully or wrongfully exercised by
                                        any Person asserting or exercising
                                        governmental or paramount powers;

                           7.6.5.1.5.   for any other consequences arising from
                                        causes beyond the control of the Issuing
                                        Bank; or

                           7.6.5.1.6.   any error, neglect or default of any
                                        correspondent of the Issuing Bank, or of
                                        any advising, confirming, negotiating or
                                        paying bank,

                           and none of the above shall lessen, invalidate or
                           otherwise prejudice any of the rights of the Issuing
                           Bank hereunder or the obligations of the Relevant
                           Borrower under Section 7.6.4.2. In furtherance and
                           not in limitation of the foregoing provisions, it is
                           agreed that any payment made by the Issuing Bank in
                           good faith in response to any demand for payment
                           under a Standby Credit shall be deemed to have been
                           properly made and shall be binding upon all parties
                           hereto and shall not result in any liability of the
                           Issuing Bank to the other parties hereto and shall
                           not lessen, invalidate or otherwise prejudice the
                           obligations of the Relevant Borrower under Section
                           7.6.4.2.

                7.6.5.2.   Notwithstanding the provisions of this Section 7.6.5,
                           no Borrower shall be responsible for, and the Issuing
                           Bank shall not be relieved of responsibility for, any
                           willful misconduct or gross negligence of or by the
                           Issuing Bank.

        7.6.6.  Payments Under Standby Credits: Each payment made by the Issuing
                Bank under or otherwise in respect of a Standby Credit which is
                not reimbursed to the Issuing Bank pursuant to Section 7.6.4.2
                on the date such payment is made shall be deemed to constitute
                an Advance under the Swing Line on the date such payment is made
                and shall be repaid by the Relevant Borrower to the Swing Line
                Lender accordingly. Each such payment made in Canadian dollars
                shall be treated as a Prime Rate Loan. Each such payment made in
                U.S. dollars shall be treated as a Base Rate Loan. Each such
                payment made in any other Currency shall be treated as a Prime
                Rate Loan in the amount of the Canadian Dollar Value of such
                payment.

        7.6.7.  Standby Credit Fees: The Relevant Borrower shall pay a fee to
                the Issuing Bank in advance on the date of issuance of each
                Standby Credit for the period from and including the date of
                issuance of the Standby Credit to and including the stated
                expiry date thereof, based on the stated amount of the Standby
                Credit on such issuance date. Such fee shall be payable in the
                Currency in which the applicable Standby Credit is denominated.
                The fee payable shall be determined as the product obtained by
                multiplying (i) the stated amount of such Standby Credit by (ii)
                the Applicable Margin and by (iii) the fraction of the number of
                days from the date of issue until the Maturity Date of such
                Standby Credit divided by the actual number of days in the year.
                In addition, the Relevant Borrower shall pay the Issuing Bank's
                prevailing scheduled rates for services (including advices,
                amendments and renewals) provided by the Issuing Bank pertaining
                to outstanding Standby Credits. All amounts paid to the Issuing
                Bank pursuant to this Section 7.6.7 shall be retained by the
                Issuing Bank for its own account.

        7.6.8.  Acceleration: On the Revolver Facility Due Date or upon the
                Agent making a declaration under Section 12.2.2, the maximum
                amount of the contingent liability of the Issuing Bank under any
                Standby Credit which is then outstanding shall immediately
                become due and payable notwithstanding that the Issuing Bank has
                not at such date been required to make payment under any such
                Standby Credit. Any such amount shall be paid to the Agent and
                shall be credited to the Cash Collateral Account and held in the
                manner contemplated by Section 7.6.10 as security for the
                repayment of future indebtedness of that Borrower to the Issuing
                Bank in respect of each Standby Credit issued for its account
                which are drawn down, and, pending the expiry of all such
                outstanding Standby Credits, any such amounts held by the Agent
                shall bear interest at the rate established by the Agent from
                time to time as that payable in respect of 30 day term deposits
                of the Agent for monies of like amount.

        7.6.9.  Conflict: Each Standby Credit shall be subject to the Issuing
                Bank's customary Standby Credit terms and procedures from time
                to time in effect and shall be in a form acceptable to the
                Issuing Bank. Each Borrower shall execute and deliver such
                standard form indemnities, bonds and other assurances as the
                Issuing Bank may reasonably require from time to time with
                respect to Standby Credits and such standard form indemnities,
                bonds and other assurances shall take effect subject to Section
                1.11. A Standby Credit shall in no event contain provisions
                requiring the Issuing Bank to satisfy itself, prior to payment
                thereunder, as to any conditions for a drawing thereunder other
                than the presentation of prescribed documents.

        7.6.10. Prepayment: If any provision of this Agreement has the effect of
                requiring a Standby Credit to be prepaid, such prepayment is
                effected by providing the Agent with cash cover in the Currency
                in which that Standby Credit is denominated, by reducing,
                whether by partial cancellation or otherwise, (in accordance
                with the terms of this Agreement and the relevant Standby
                Credit) the amount that may be demanded under that Standby
                Credit (or by such amount automatically reducing in accordance
                with the terms of the relevant Standby Credit) or by canceling
                that Standby Credit by returning the original to the Issuing
                Bank together with written confirmation (in form and substance
                satisfactory to the Issuing Bank) from the beneficiary that the
                Issuing Bank has no further liability under that Standby Credit.
                "cash cover" is provided, in whole or in part, in respect of a
                Standby Credit at any time by paying an amount, in the Currency
                in which that Standby Credit is denominated, equal to the whole
                or a part of the maximum amount which may be drawn under such
                Standby Credit at such time to the Agent, to be held by the
                Agent pursuant to the Relevant Borrower's debenture listed in
                Schedule L and the Agent paying the amount so received by it
                into an interest bearing account with it in the name of the
                Relevant Borrower (a "Cash Collateral Account") from which the
                only withdrawals which may be made until the relevant Standby
                Credit is otherwise cancelled or expires or prepaid in its
                entirety
<PAGE>
                                      -68-


                are withdrawals to pay the Agent amounts due and payable to it
                under this Agreement following any payment made by it under such
                Standby Credit. If a Standby Credit is cancelled or expires or
                is returned to the Issuing Bank by the beneficiary for
                cancellation without payment, then, so long as no Event of
                Default has occurred, the Relevant Borrower shall thereafter be
                free to withdraw any remaining credit balance in the Cash
                Collateral Account.

7.7. LIBOR Loans - Market Disruption

            If at any time prior to the commencement of any Interest Period, any
Lender (an "Affected Lender") shall have determined and gives notice to the
Agent (which will promptly notify the Borrowers and the other Lenders) that it
has become unlawful or impossible for that Lender to make, maintain or fund any
LIBOR Loan or that the Lender's ability to make, maintain or fund such LIBOR
Loan has been materially adversely affected because:

        7.7.1.  of circumstances affecting the London interbank market or
                elsewhere which result in there not existing adequate and fair
                means for ascertaining the rate of interest applicable to such
                LIBOR Loan during such Interest Period;

        7.7.2.  deposits in U.S. dollars are not being offered to a Lender in
                the London interbank market or elsewhere in sufficient amounts
                in the ordinary course of business; or

        7.7.3.  any Change in Law or any change in national or international,
                financial, political or economic conditions or currency exchange
                rates or exchange control,

then, from and after the date of such determination for so long as such
condition shall continue to exist, no Borrower shall have the right to obtain or
maintain a participation in any LIBOR Loan from the Affected Lender. When the
Affected Lender has made any such determination, upon notice thereof by the
Agent to the Relevant Borrower, the Relevant Borrower shall on the last day of
the then current Interest Period applicable to the participation of the Affected
Lender in any LIBOR Loan owing by the Relevant Borrower to such Lender either
(i) repay to the Affected Lender its participation in such LIBOR Loan together
with all unpaid interest accrued thereon to the date of repayment and all other
amounts payable to the Affected Lender hereunder in respect of such LIBOR Loan
or (ii) convert its participation in such LIBOR Loan to another form of Loan
under the same Credit Facility in the same Currency.

7.8. Illegality

            If any Change in Law shall make it unlawful or impossible for any
Lender (an "Affected Lender") to make, maintain or fund its participation in any
Advance, such Affected Lender shall promptly give notice to the Agent which will
promptly give notice to the Borrowers and the other Lenders. Upon the Agent
giving such notice the obligation of the Affected Lender
<PAGE>
                                      -69-


to make or continue its participation in such Advances, which it would be
unlawful or impossible for such Lender to make or continue, shall be suspended
for so long as such condition shall exist. Upon receipt of such notice the
Relevant Borrower shall either (i) convert each participation of the Affected
Lender in each affected Advance to another Type of Advance under the same Credit
Facility in the same Currency or (ii) repay the Affected Lender's participation
in such Advance together with all unpaid interest accrued thereon to the date of
repayment and all other amounts payable hereunder to such Affected Lender in
respect of such Advance, in either case (A) on the Maturity Date applicable to
each such Advance, if the Affected Lender may lawfully continue to maintain and
fund its participation in such Advance to such date, or (B) immediately if the
Affected Lender may not lawfully continue to fund and maintain its participation
in such Advance to such dates and the Relevant Borrower promptly shall pay any
compensation owing to such Lender under Section 8.3 in consequence thereof. If
the Relevant Borrower fails to select (i) or (ii), the Relevant Borrower shall
be deemed to have selected to prepay such Affected Lender's participation in any
affected Advance.

7.9. Facility Excesses by Reason of Foreign Currency Fluctuations

            If and each time the Agent determines (which determination shall be
conclusive and bind the Borrowers, absent manifest error) that the Outstanding
Amount of all Advances under either Credit Facility exceeds 102% of the Revolver
Commitment or Total Term Commitment, as the case may be, by reason of
fluctuations in exchange rates, the Agent may request (or if such excess is more
than five percent (5%) of the Revolver Commitment or Total Term Commitment, as
applicable, shall request) the Borrowers to repay the excess. Within five
Banking Days of the receipt of any such request, each Relevant Borrower with
Advances outstanding under the relevant Credit Facility shall repay to the
Lenders such Advances outstanding under such Credit Facility as may be required
to ensure that such excess is eliminated.

7.10. Evidence of Indebtedness

       7.10.1.  The indebtedness of each Borrower to each Lender hereunder
                resulting from all Loans shall be evidenced by the loan accounts
                which shall be opened and maintained by the Agent. The Agent
                shall debit in its accounts the amount of all such indebtedness
                and shall credit therein each repayment of such indebtedness by
                appropriate entries. Entries recorded by the Agent or its
                employees on a loan history statement for each Borrower, shall
                be prima facie evidence thereof, absent manifest error. The
                failure of the Agent to record any such amount or date shall not
                affect the obligation of a Borrower to pay amounts due hereunder
                in accordance with this Agreement.
<PAGE>
                                      -70-


       7.10.2.  Any Lender may request that its Rateable Share in Advances be
                evidenced by a promissory note (a "Note"). In such event, each
                Borrower shall prepare, execute and deliver to such Lender a
                Note payable to the order of such Lender in a form supplied by
                the Agent. Thereafter, the Rateable Share of such Lender in all
                outstanding Advances evidenced by such Note and interest thereon
                shall at all times (including after any transfer pursuant to
                Section 14.5) be represented by one or more Notes payable to the
                order of the payee named therein or any Transferee, except to
                the extent that any such Lender or Transferee subsequently
                returns any such Note for cancellation and requests that its
                Rateable Share on outstanding Advances once again be evidenced
                as described in Subsection 7.10.1.

                                   ARTICLE 8.
                                FEES AND EXPENSES

8.1.  Commitment Fee

       8.1.1.   Gerdau Steel shall pay to the Agent for the account of the
                Lenders a commitment fee in respect of the Revolver Facility
                calculated at the Applicable Margin. Such Applicable Margin
                shall be computed upon the amount by which the Maximum Amount of
                the Revolver Facility exceeds the daily aggregate Outstanding
                Amount of all Advances under the Revolver Facility.

       8.1.2.   Gerdau Steel shall pay to the Swing Line Lender for its own
                account a commitment fee in respect of the Swing Line calculated
                at the Applicable Margin. Such Applicable Margin shall be
                computed upon the amount by which the Swing Line Amount exceeds
                the daily aggregate Outstanding Amount of all Advances under the
                Swing Line.

       8.1.3.   Each commitment fee payable pursuant to this Section 8.1 shall
                be calculated for each calendar quarter from and after the date
                hereof until the Revolver Facility Due Date and shall be payable
                quarterly in arrears on the third Banking Day of the immediately
                following calendar quarter. The first payment of such fee shall
                be due and payable on the third Banking Day of the first
                calendar quarter commencing after the day the Implementation
                Notice is given.

8.2. Payment of Costs and Expenses

            Whether or not any Borrower obtains any Advances hereunder,
the Borrowers shall pay to the Syndicate on demand all reasonable out-of-pocket
costs and expenses of the
<PAGE>
                                      -71-


Syndicate and each of their respective agents, officers and employees and any
receiver or receiver-manager appointed by the Agent or by a court in connection
with this Agreement or any other Loan Document, including:

       8.2.1.   the preparation, execution, filing and registration of this
                Agreement or any of the other New Loan Documents, any actual or
                proposed amendment or modification of any of the Loan Documents
                or any waiver hereunder or thereunder and all instruments
                supplemental or ancillary thereto;

       8.2.2.   obtaining advice as to any Lender's rights or obligations under
                any of the Loan Documents; and

       8.2.3.   the defence, establishment, protection or enforcement of any of
                the rights of any Lender under any of the Loan Documents
                including all costs and expenses of establishing the validity,
                enforceability and priority of, or of collection of amounts
                owing under, any of the Loan Documents or of any enforcement of
                the Security,

and further including all of the fees, expenses and disbursements of the
Lenders' Counsel, on a solicitor and client scale, incurred in connection with
any of the foregoing, and including all Sales Taxes payable by any Lender
(whether refundable or not) on all such fees, costs and expenses.

8.3. Indemnity

            The Relevant Borrower shall compensate each Lender for all losses
and expenses including any losses and expenses sustained by any Lender in
connection with the liquidation or re-employment in whole or in part of deposits
or funds borrowed or acquired by the Lender to fund any Advance to the Relevant
Borrower which the Lender may sustain or incur: (i) if for any reason a
Drawdown, Conversion or Rollover does not occur on a date requested by such
Borrower, (ii) if the Relevant Borrower fails to give any notice required to be
given by it hereunder, in the manner and at the time specified herein, (iii) as
a consequence of any failure by the Relevant Borrower to repay any Loan
Obligations when required by the terms of this Agreement, or (iv) if the whole
or any part of any Advance owing by the Relevant Borrower is paid to the Lender
or converted to another form of Advance other than on the Maturity Date thereof.
A certificate of a Lender provided to the Agent setting forth the amounts
claimed by the Lender as compensation under this Section 8.3 in respect of such
losses and expenses shall be conclusive and binding on the parties hereto,
absent manifest error, and the Relevant Borrower shall forthwith pay to the
Agent for the account of the Lender the amount of compensation set out in each
such certificate.

8.4. Agency Fee

            Gerdau shall pay the Agent for its own account the agency fees
stipulated in the Agency Fee Agreement at the times therein provided.

                                   ARTICLE 9.
                             SECURITY AND INSURANCE

9.1. Security

            In addition to the Prior Security, and as security for the due and
punctual payment and performance of all Loan Obligations of each Borrower, the
Borrowers shall deliver or cause to be delivered to and for the benefit of the
Syndicate, the New Loan Documents at or before the Term Drawdown Date.

9.2. Perfection

            Each Borrower shall ensure that all the Security referred to in
Section 9.1 is executed and delivered and that the Liens created thereby are
registered, filed, recorded and perfected at or prior to the time the
Implementation Notice is given in all jurisdictions reasonably required by the
Agent.

9.3. Security Effective Notwithstanding Date of Advance

            The Liens constituted or required to be created under the Security
shall be effective and the undertakings therein in respect thereto shall be
continuing, whether the monies hereby or thereby secured or any part thereof
shall be advanced before or after or at the same time as the creation of any
such Liens or before or after or upon the date of this Agreement. The Security
shall not be affected by any payments on the Advances, or by the balance of the
Advances fluctuating from time to time, but shall constitute continuing security
to the Lenders for the Loan Obligations from time to time.

9.4. No Merger

            The security constituted by the Security shall not merge in any
other security. No judgment obtained by the Agent shall in any way affect any of
the provisions of this Agreement or the Security. For greater certainty, no
judgment obtained by any Lender shall in any way affect the Obligation of any
Borrower to pay interest and fees at the rates, times and in the manner provided
in this Agreement.
<PAGE>
                                      -73-


9.5. Prior Security

        9.5.1.  Each Borrower confirms that the Prior Security shall remain in
                full force and effect notwithstanding amendments to the Prior
                Loan Agreement reflected in this Agreement and shall continue to
                secure the Loan Obligations until repayment in full of all of
                the Loan Obligations. For greater certainty, (i) Courtice agrees
                with and confirms to the Lenders that as at the time the
                Implementation Notice is issued no amount shall have been paid
                by it in reduction of the amounts secured under the Courtice
                Debenture, as amended by Amending Agreement No. 1 and Amending
                Agreement No. 3, or the Courtice Supplemental Debenture, as
                amended by Amending Agreement No. 2, and that such Security
                collectively shall secure Loan Obligations of Courtice in an

                             to the best of its knowledge, its predecessors in
                             title in material compliance with all Environmental
                             Laws.

      10.1.16.  All Material Information Supplied. No information furnished by
                it to the Syndicate in connection with any of the Loan Documents
                contains any material misstatement of fact or omits to state a
                material fact necessary to make the statements contained therein
                not misleading in light of the circumstances in which they were
                made and as of the date made. Each financial forecast and
                projection ("Forecast") prepared by it and furnished to the
                Syndicate was based upon assumptions believed to be reasonable
                by it as of the date of preparation; there has been no material
                change in such assumptions or in the information on which such
                assumptions are based which has not been disclosed in writing to
                the Syndicate; it has no reason to believe that any such
                Forecast as it relates to periods ending after its date of
                preparation, when read in conjunction with the related
                assumptions and other information disclosed in writing to the
                Agent, fails to reflect its judgment as the most probable set of
                economic conditions its planned courses of action given these
                conditions, and such Forecast as it relates to periods already
                ended, does not reflect results which are materially higher than
                the anticipated actual results for such periods.

      10.1.17.  No Material Adverse Change. Since the date of its most recent
                financial statements of Gerdau Steel furnished to the Syndicate,
                there has been no change in any of its Business Affairs which
                could have a Material Adverse Effect.

      10.1.18.  Compliance with Laws. It is in compliance in all material
                respects with all Applicable Laws, non-compliance with which
                could give rise to a Material Adverse Change. It has obtained
                all Permits and made all Registrations necessary for the conduct
                of its Business.

      10.1.19.  Unfunded Pension Liabilities. It does not have any unfunded
                liabilities in respect of which it is in default arising out of
                any employee pension plan or any other employee benefit plan to
                which it is a party or by which it is bound, and all requisite
                employer contributions required thereunder to date have been
                made. There is no Award outstanding and no pending or,

                to its knowledge, threatened Litigation against any such plan,
                any fiduciary thereof, or any Gerdau Canada Group Member with
                respect thereto which could have a Material Adverse Effect.

                                             by each Gerdau Canada Group Member,

                percentage of all issued Capital Stock held by Gerdau Steel,
                directly or indirectly.

      10.1.25.  Year 2000 Problem. Each Gerdau Canada Group Member has carefully
                reviewed and identified all material aspects of the Gerdau
                Canada Group's Business which could be adversely affected by the
                "Year 2000 Problem" (ie., the risk that computer applications
                may be unable to recognize and properly perform date sensitive
                functions for periods ending in the next millennium). The
                software used in the Gerdau Canada Group's Business is to the
                best of its knowledge Year 2000 Compliant. For this purpose,
                "Year 2000 Compliant" means:

                10.1.25.1.   The software accepts, calculates, compares, sorts,
                             extracts, sequences, and otherwise processes date
                             inputs and date values (whether forward or
                             backward), and returns, generates, processes and
                             displays date output and date values (collectively,
                             the "Processes"), accurately, without
                             interruptions, and in a consistent manner (without
                             errors or omissions due to date selection),
                             regardless of the date used, and whether before, on
                             or after January 1, 2000 and whether or not the
                             dates are affected by leap years;

                10.1.25.2.   The software accepts and responds to two-digit
                             year-date input in a manner that resolves any
                             ambiguities as to the century in a defined,
                             predetermined, and appropriate manner; and

                10.1.25.3.   The software stores, processes and displays date
                             information (including in user interfaces and data
                             fields) in ways that are unambiguous as to the
                             determination of the century in a defined,
                             predetermined and appropriate manner.

      10.1.26.  Employee Relations. There are no strikes, work stoppages or
                controversies pending or, to its knowledge, threatened between
                any Gerdau Canada Group Member and any of its employees
                (including unions representing employees), other than employee
                grievances arising in the ordinary course of business which
                would not reasonably be likely to result in work stoppages, and
                other than those disclosed in writing to the Lenders.

                or a company "controlled" by an "investment company" within the
                meaning of the United States Investment Company Act of 1940, as
                amended. No Gerdau Canada Group Member is subject to regulation
                under the United States Public Utility Holding Company Act of
                1935, as amended.

      10.1.28.  Federal Reserve Regulations. No Gerdau Canada Group Member is
                engaged, directly or indirectly, principally or as one of its
                important activities, in the business of extending, or arranging
                for the extension of, credit for the purpose of purchasing or
                carrying margin stock (as defined in Regulation U). Neither the
                borrowing of any Advance hereunder, nor the use of the proceeds
                thereof, will (i) be used to purchase or carry any "margin
                stock" within the meaning of Regulation U, or (ii) violate or be
                inconsistent with the provisions of Regulation U. None of the
                assets which are subject to any limitation on sale, pledge or
                other restriction under the Loan Documents have been, or will
                be, margin stock.

      10.1.29.  Chief Executive Office. The location of the chief executive
                office (as that term is used in Section 7(4) of the Personal
                Property Security Act (Ontario) of each Gerdau Canada Group
                Member is listed in Schedule P.

                and performance of obligations under each Loan Document by each
                party thereto and the consummation of the transactions
                contemplated in each Loan Document (including the creation of
                the Security contemplated thereby) are permitted by, and do not
                and will not violate or breach any obligation under or give rise
                to any default, Potential Event of Default or Event of Default
                (each as defined in each Gerdau S.A. Trust Deed) or similar such
                event (howsoever described) under either Gerdau S.A. Trust Deed.

10.2. Survival of Representations and Warranties

            Each of the Borrowers covenants that the representations and
warranties made by it in this Article 10 shall be true and correct on each day
that this Agreement remains in force and effect, and all such representations
and warranties shall be deemed to be made on each such day with the same effect
as if such representations and warranties had been made and given on and as of

                             extent of the environmental liability or condition

                             assistance, by means of Investments, guarantees,

                released within 10 Banking Days or such shorter period as would

                thereunder.

      12.1.9.   Impossibility. Any Change in Law occurs which has given rise or
                could reasonably be expected to give rise to a Material Adverse
                Change.

      12.1.10.  Insolvency. Any Gerdau S.A. Group Member does not generally pay
                its debts as they become due or admits its inability to pay its

                creditors or commits an act of bankruptcy (within the meaning of
                the Bankruptcy and Insolvency Act (Canada)) or any proceedings

                seeking to adjudicate it a bankrupt or insolvent or seeking
                liquidation, winding-up, reorganization, compromise,
                arrangement, adjustment, protection, relief or composition of it
                or of its debts under any Applicable Law relating to bankruptcy,
                insolvency or reorganization or relief of debtors or other

                manager, receiver and manager, trustee, custodian or other
                similar official for it or for any substantial part of its
                Business Assets (excluding proceedings being contested by such
                Gerdau S.A. Group Member in good faith by appropriate
                proceedings so long as enforcement remains stayed, none of the
                relief sought is granted (either on an interim or permanent
                basis) and such proceedings are dismissed within 15 days of
                their commencement); or any Gerdau S.A. Group Member takes
                corporate action to authorize any of the actions set forth above

                determined adversely to any Gerdau S.A. Group Member or to the
                rights of the Syndicate, could reasonably be expected to give
                rise to a Material Adverse Change, or any Gerdau S.A. Group
                Member or any other person party to any Loan Document denies
                that it has any or further obligations thereunder.

      12.1.13.  Material Adverse Change. Any Material Adverse Change occurs.

      12.1.14.  Change of Ownership. Any Person, or more than one Person acting
                in concert, (other than Gerdau S.A.) acquires ownership or
                Control of any Capital Stock of Gerdau Steel, unless the
                Majority Lenders consent to such acquisition. Any Gerdau Canada
                Group Member (other than Gerdau Steel) ceases to be a
                Wholly-Owned Subsidiary of Gerdau Steel or Gerdau Steel ceases
                to own and Control, directly or indirectly, all of the Capital
                Stock of any Gerdau Canada Group Member that is a general or
                limited partnership. Gerdau Steel ceases to own and Control

                the Voting Capital Stock of FLS or FLS ceases to own and Control
                at least eighty-five percent (85%) of the Voting Capital Stock
                of AmeriSteel.

      12.1.15.  Condemnation. Any court, government or governmental agency shall
                condemn, seize, expropriate or otherwise appropriate, or take
                custody or control of, all or any Substantial Portion of the
                property of any Gerdau S.A. Group Member which, when taken
                together with all other property of any Gerdau S.A. Group Member
                so condemned, seized, expropriated, appropriated, or taken
                custody or control of, during the twelve-month period ending
                with the month in which any such action occurs, constitutes a
                Substantial Portion.

12.2. Remedies Upon Default

            Upon the occurrence of any Event of Default, the Agent may (or, at
the direction of the Majority Lenders, shall) do any one or more or all of the
following:

      12.2.1.   declare the whole or any part of the unutilized portion (if any)
                of the Credit Facilities to be terminated or reduced, whereupon
                the Lenders shall not be required to make any further Drawdowns
                or permit any further Conversions or Rollovers (other than
                conversions of maturing Bankers' Acceptances to Prime Rate Loans
                and LIBOR Loans to Base Rate Loans);

      12.2.2.   declare all or any item or part of the Loan Obligations to be
                immediately due and payable, whereupon they shall become so due
                and payable;

      12.2.3.   suspend any right of a Borrower under any Loan Document;

      12.2.4.   demand payment under any guarantee comprised in the Security;

      12.2.5.   realize upon all or part of the Liens constituted under the
                Security; and

      12.2.6.   take any other action, commence any other suit, action or
                proceeding or exercise such other right as may be permitted at
                law or in equity (whether or not provided
<PAGE>
                                      -99-


                for herein or in any other Loan Document) at such times and in
                such manner as the Agent may consider expedient,

all without, except as may be required by Applicable Law, any additional notice,
presentment, demand, protest, noting of protest, dishonour or any other action.
The rights of the Syndicate hereunder are cumulative and are in addition to and
not in substitution for any other rights or remedies provided by Applicable Law
or by the Security.

12.3. Payment of Bankers' Acceptances

            Immediately upon the Agent making a declaration pursuant to Section
12.2.2, the Relevant Borrower shall, without the necessity of further act or
evidence, be and become unconditionally obligated to deposit with the Agent the
aggregate face amount of all Bankers' Acceptances then outstanding for the
Relevant Borrower's account and the Relevant Borrower hereby authorizes each
Lender to debit any then existing credit in its accounts with the amount
required to make such payment to the Agent notwithstanding that any such
Bankers' Acceptances may be held by the Lender in its own right at maturity.
Amounts paid to the Agent pursuant to this Section 12.3 shall bear interest at
the rate offered by the Agent on deposits of similar amounts for similar terms.
All such amounts, together with interest earned thereon, shall be applied
against and shall reduce to the extent of such amounts the Relevant Borrower's
obligations to pay amounts then or thereafter payable under Bankers' Acceptances
at the respective times such amounts become so payable. Any remaining cash being
held by the Agent pursuant to this Section 12.3 shall be applied against any
other Loan Obligations and any excess thereafter shall be released to the
Relevant Borrower or its assigns, but only after all Bankers' Acceptances have
matured and all Loan Obligations have been satisfied in full.

12.4. Lenders' Right of Advance

            In the event that a Borrower fails to comply with its Loan
Obligations under Section 12.3 or 7.6.8, each Lender may, at such time, in its
discretion, make an Advance by way of a Prime Rate Loan under the relevant
Credit Facility on behalf of the Relevant Borrower in an amount not exceeding
its participation in the Outstanding Amount of all outstanding Bankers'
Acceptances or the Outstanding Amount of all outstanding Standby Credits under
such Credit Facility (even if such Advance results in such Lender's
participation in the aggregate Outstanding Amount of all Loans under any Credit
Facility exceeding its Revolver Commitment or Term Commitment, as applicable)
and hold the proceeds of such Loan as security for the obligations of the
Relevant Borrower to indemnify such Lender in respect of such Bankers'
Acceptances on their maturity to be applied in accordance with Section 12.3 or
such Standby Credits under Section 7.6.8.

12.5. Distributions

            All distributions under or in respect of any of the Security shall
be held by any Lender on account of the Loan Obligations without prejudice to
any claim by any Lender for any deficiency after such distributions are received
by any Lender and each Borrower shall remain liable for any such deficiency. All
such distributions may be applied to such part of the Loan Obligations as each
Lender may see fit in its sole discretion, and each Lender may at any time
change any appropriation of any such distributions or other moneys received by
it and reapply the same against any other part of the Loan Obligations as each
Lender may see fit, notwithstanding any previous application.

                                   ARTICLE 13.
                          THE AGENT AND ADMINISTRATION
                            OF THE CREDIT FACILITIES

delegated to the Agent by the terms thereof, together with such rights as are
reasonably incidental thereto.

13.2. Declaration of Agency

            The Agent declares that it shall hold the Security, the Collateral
charged thereby and the rights granted to it under each other Loan Document for

by the Agent in accordance with this Article Fourteen.

13.3. Protection of Agent

13.5. Consultation with Professionals

            The Agent may engage and consult with the Lenders' Counsel,
accountants, consultants, financial advisors and other experts and the Agent

faith and in accordance with the advice and opinion of the Lenders' Counsel or
such accountants, consultants, financial advisors or other experts.

13.6. Documents

            The Agent shall not be under any duty or obligation to examine,
enquire into or pass upon the validity, effectiveness or genuineness of any Loan
Document or any other agreement, document, instrument, or communication

shall be entitled to assume that the same are valid, effective and genuine, have
been signed or sent by the proper parties and are what they purport to be.

13.7. Agent and its Subsidiaries and Affiliates

            With respect to its Revolver Commitment, its Term Commitment and
those portions of the Credit Facilities made available by it, the Agent shall
have the same rights hereunder as any other Lender and may exercise the same as

may accept deposits from, lend money to and generally engage in any kind of
business with any Gerdau Canada Group Member and its Affiliates and Persons
doing business with any Gerdau Canada Group Member or any of its Affiliates as
if it were not the Agent and without any obligation to account therefor.

13.8. Responsibility of the Agent

            The obligations of the Agent to the Lenders under each Loan Document
are only those expressly set forth in such Loan Document, subject as otherwise
provided in this Article Thirteen. The Agent shall not have any fiduciary
obligation to any Lender. The Agent shall only have those contractual
obligations expressly set forth in each Loan Document. The Agent shall not have
any duty or obligation to investigate whether a Default or an Event of Default
has occurred. The Agent shall be entitled to assume that no Default or Event of
Default has occurred and is continuing, unless any officer of the Agent charged
with the administration of the Loan Documents has actual knowledge or has been
notified by a Borrower of such fact or has been notified by a Lender that such
Lender considers that a Default or Event of Default has occurred and is
continuing, such notification to specify in detail the nature thereof.

      13.9.1.   The Agent shall be entitled to use its discretion with respect
                to exercising or refraining from exercising any rights which may
                be vested in it by and with respect to taking or refraining from
                taking any action which it may be able to take under or in
                respect of any Loan Document, unless the
<PAGE>
                                     -102-


                Agent has been instructed by the Required Lenders to exercise
                such rights or to take or refrain from taking such action;
                provided, however, that the Agent shall not release or postpone
                any guarantee of any Gerdau S.A. Group Member or release,
                discharge or subordinate any Lien created under any Security
                without the consent of all the Lenders, unless expressly
                permitted or required to do so by the provisions of any Loan
                Document. The Agent shall not incur any obligations under or in
                respect of any Loan Document with respect to anything which it
                may do or refrain from doing in the reasonable exercise of its
                judgment or which may seem to it to be necessary or desirable in
                the circumstances, except for its gross negligence or willful
                misconduct.

      13.9.2.   The Agent shall in all cases be fully protected in acting or
                refraining from acting under any Loan Document in accordance
                with the instructions of the Required Lenders, and any action
                taken or failure to act pursuant to such instructions shall be
                binding on all Lenders.

      13.9.3.   Notwithstanding anything else herein contained, the Agent may
                refrain from doing anything which would or might in its opinion
                be contrary to any Applicable Law or which would or might
                otherwise render it liable to any Person and may do anything
                which is, in its opinion, necessary to comply with any
                Applicable Law.

      13.9.4.   Without prejudice to the provisions of any other Loan Document,
                the Agent shall have the right, but not the obligation to insure
                any of the Collateral or to require any other Person to maintain
                any such insurance and it shall not be responsible for any
                losses and expenses which may be suffered by any Person as a
                result of the lack of or inadequacy or insufficiency of any such
                insurance.

      13.9.5.   The Agent shall have the right to institute, prosecute and
                defend any Litigation affecting the Agent, the Collateral or the
                Security and to compromise any matter or difference or submit
                any such matter or difference to arbitration and to compromise
                or compound any debts owing to the Agent as agent or any other
                claims against it as such agent upon being provided with such
                evidence as shall seem sufficient to the Agent.

      13.9.6.   The Agent shall have the right to give or enter into any
                obligation as it shall, with the approval of the Required
                Lenders and subject to all of the provisions of the Loan
                Documents, think fit in relation to the Collateral or the
                Security.
<PAGE>
                                     -103-


      13.9.7.   Notwithstanding Subsection 13.9.1, the Agent may refrain from
                acting in accordance with any instructions of the Required
                Lenders to begin any Litigation, or to take management or
                control of any Collateral, arising out of or in connection with
                any Loan Document until it has received such security as it may
                require (whether by way of payment in advance or otherwise) for
                all losses and expenses and disbursements which it will or may
                expend or incur in complying with such instructions.

      13.9.8.   Where the Agent is obliged by the provisions of this Article
                Thirteen to give any notice or notification "promptly" or
                "forthwith", if it gives such notice or notification within two
                Banking Days of an officer of it charged with the administration
                of this Agreement becoming aware of the subject matter of such
                notice or notification, it shall be deemed to have given such
                notice or notification promptly or forthwith.

13.10. Notice of Events of Default

            In the event that an officer of the Agent charged with the
administration of this Agreement is notified of any Default or Event of Default,
the Agent shall promptly notify the Lenders, and, subject to Section 13.9, the
Agent shall take such action and assert such rights under the Loan Documents as
the Majority Lenders shall request in writing, and the Agent shall not be
subject to any liability by reason of its acting pursuant to any such request.
Prior to receiving any instructions from the Required Lenders in respect of such
Default or Event of Default, the Agent may, but shall not be obliged to, take
such action or assert such rights (other than those matters requiring unanimous
Lender consent under any other provision of this Agreement) as it deems in its
discretion to be advisable for the protection of the Lenders, except that, if
the Required Lenders have instructed the Agent not to take such action or assert
such rights, in no event shall the Agent act contrary to those instructions.

13.11. Responsibility Disclaimed

            The Agent in such capacity shall not be under any obligation
whatsoever:

      13.11.1.  to any Gerdau Canada Group Member as a consequence of any

                Lender of any of its obligations under any Loan Document;

      13.11.2.  to any Lender, as a consequence of any failure or delay in

      13.11.3.  to any Lender for any statements, representations or warranties

                information
<PAGE>

                provided pursuant to any Loan Document or any other agreement,
                document or instrument contemplated by any Loan Document or for
                the validity, effectiveness, enforceability or sufficiency of
                any Loan Document or any other agreement, document or instrument
                contemplated thereby.

13.12. Indemnification

      13.12.1.  Each of the Lenders severally agrees to indemnify the Agent (to

                pro rata according to their respective Rateable Shares from and
                against any and all losses and expenses or disbursements of any
                kind or nature whatsoever which may be imposed on, incurred by
                or asserted against the Agent in any way relating to or arising
                out of any Loan Document or any other agreement, document or
                instrument contemplated thereby or any action taken or omitted
                by the Agent under any Loan Document or any agreement, document
                or instrument contemplated thereby, except that no Lender shall
                be liable to the Agent for any portion of such losses and
                expenses or disbursements resulting from the gross negligence or
                willful misconduct of the Agent.

      13.12.2.  The Agent may indemnify itself out of the Collateral charged by
                the Security, or any funds received by the Agent pursuant to
                Section 13.20 against all of the losses and expenses or
                disbursements suffered or incurred by the Agent in connection
                with any matter or thing done or omitted to be done in any way
                relating to any Loan Document.

13.15 and 13.20 to the Agent shall (to the extent the context so admits) be
deemed to include the Agent and its directors, officers, employees, agents,
solicitors, accountants, consultants, financial advisors, other experts and all
other representatives and the Agent shall be constituted as agent and bare
trustee of each such Person and shall hold and enforce their rights under those
Sections for their respective benefits.

13.14. Credit Decision

            Each Lender represents and warrants to the Agent that:

      13.14.1.  in making its decision to enter into this Agreement and to make
                its Revolver Commitment, Term Commitment and its portion of the
                Credit Facilities available to the Borrowers, it has
                independently taken whatever steps it considers necessary to
                evaluate the financial condition and affairs of each Gerdau S.A.
                Group Member and that it has made an independent
<PAGE>
                                     -105-


                credit judgment without reliance upon any information furnished
                by the Agent; and

      13.14.2.  so long as any portion of the Credit Facilities is being
                utilized by a Borrower, it will continue to make its own
                independent evaluation of the financial condition and affairs of
                each Gerdau Canada Group Member.

13.15. Replacement Agent and Reference Lenders

      13.15.1.  The Agent (a "Resigning Agent") may resign at any time by giving
                written notice thereof to the Lenders and Gerdau Steel. Such
                resignation will not be effective until a replacement agent is
                appointed. Upon receipt of notice of any such intended
                resignation, the Majority Lenders and the Borrowers shall have
                the right to appoint a replacement to the Resigning Agent who
                shall be one of the Lenders. If no replacement to the Resigning
                Agent shall have been so appointed and shall have accepted such
                appointment within 15 days of receipt of such notice, the
                Lenders (excluding the Resigning Agent) shall within the
                following 15 days appoint a replacement who may, but need not
                be, a Lender. If the Lenders fail to appoint a replacement to
                the Resigning Agent within such 15 day period, without
                limitation of its rights under this Section, the Resigning Agent
                may, on behalf of the Lenders, appoint a replacement Agent which
                shall be a financial institution organized under the laws of
                Canada (or a Province) which has (or whose Holding Body
                Corporate has) combined capital and reserves in excess of Cdn
                $1,000,000,000 or the Equivalent Amount in foreign currency and
                has an office in Toronto. Upon the resignation of a Resigning
                Agent, the replacement administration agent shall thereupon
                succeed to and become vested with all the rights and obligations
                of the Resigning Agent and the Resigning Agent shall be
                discharged from its obligations under the Loan Documents. A
                replacement administration agent shall evidence its acceptance
                of appointment hereunder by signing and delivering a counterpart
                of this Agreement. After any Resigning Agent's resignation or
                removal hereunder as Agent the provisions of this Article
                Thirteen shall continue in effect for its benefit in respect of
                any actions taken or omitted to be taken by it while it was
                acting as Agent.

      13.15.2.  The Agent may nominate up to three Lenders to act as Reference
                Lenders under this Agreement. Any Reference Lender may resign at
                any time by giving notice thereof to the Agent. Upon receipt of
                such notice, the Agent may appoint a replacement Reference
                Lender who shall be one of the Lenders.
<PAGE>
                                     -106-


      13.15.3.  The Swing Line Lender may resign at any time by giving notice
                thereof to the Agent. Upon receipt of such notice, the Majority
                Lenders shall appoint a replacement Swing Line Lender who shall
                be one of the Lenders.

13.16. Delegation

            With the prior approval of the Majority Lenders, such approval not
to be unreasonably withheld, the Agent shall have the right to delegate any of
its rights, duties or obligations under the Loan Documents as Agent to any other
Person upon such terms and conditions as the Agent may think fit and the Agent
shall not be bound to supervise the proceedings or be in any way responsible for
any obligations or losses and expenses incurred by reason of any misconduct or
default on the part of any such delegate.

13.17. Required Lender Decisions

            Where the Required Lenders are required to consent to any act or
thing under any Loan Document, the Agent shall ask all Lenders for such consent
to do any such act or thing. The foregoing shall not limit the right of the
Required Lenders to consent to any such act or thing. A copy of such consent
shall be sent by the Agent to all the Lenders.

13.18. Waivers and Amendments

      13.18.1.  The rights of each Lender under each Loan Document shall be
                cumulative and not exclusive of any rights which each Lender
                would otherwise have, and no failure or delay by any Lender in
                exercising any right shall operate as a waiver of it nor shall
                any single or partial exercise of any right preclude its further
                exercise or the exercise of any other right. Subject as
                otherwise provided in Subsections 13.18.2 and 13.18.3, any term,
                covenant, agreement, or condition of any Loan Document may only
                be amended with the consent of the Relevant Borrower and the
                Majority Lenders or compliance therewith may only be waived
                (either generally or in a particular instance and either
                retroactively or prospectively) by the Majority Lenders.

      13.18.2.  Without the prior consent of every Lender, no amendment, waiver
                or other action referred to in Subsection 13.18.1 shall:

                13.18.2.1.   increase the aggregate amount of any Credit
                             Facility, the amount or term of any of the Revolver
                             Commitments, the Term Commitments or the proportion
                             represented by the Rateable Share of any Lender;
<PAGE>
                                     -107-


                  13.18.2.2.    postpone or defer the time for the payment of
                                the principal of or interest on any Advance, any
                                Stamping Fee, Commitment Fee or any other amount
                                payable hereunder;

                  13.18.2.3.    decrease the rate or amount or change the
                                currency of any principal, interest or fees
                                (including Stamping Fees and Commitment Fee)
                                payable hereunder or the requirement of pro rata
                                application in accordance with each Lender's
                                Rateable Share of all amounts received by the
                                Agent in respect of each Credit Facility;

                  13.18.2.4.    change the definition of "Required Lenders" or
                                "Majority Lenders";

                  13.18.2.5.    amend Sections 13.22, 13.25 or this Section
                                13.18; or

                  13.18.2.6.    release or postpone any guarantee of any Gerdau
                                Canada Group Member under any Loan Document or
                                release, discharge or subordinate any Lien
                                created under the Security except as otherwise
                                expressly permitted or required by the
                                provisions of any Loan Document.

        13.18.3.  No amendment or waiver of any provision of any Loan Document
                  shall affect any of the rights or obligations of the Agent,
                  the Swing Line Lender or Issuing Bank under any Loan Document
                  without the prior consent of the Agent, Swing Line Lender or
                  Issuing Bank.

13.19. Determination by Agent

        13.19.1.  Good Faith. Any determination to be made by the Agent under
                  any Loan Document shall be made by the Agent in good faith
                  and, if so made, shall be conclusive and binding on all
                  parties, absent manifest error.

        13.19.2.  Certificate of the Agent as to Rates. A certificate of the
                  Agent certifying any amount or interest or discount rate shall
                  be conclusive and binding on the parties hereto for all
                  purposes, absent manifest error. No provision hereof shall be
                  construed so as to require the Agent to issue a certificate at
                  any particular time.

        13.19.3.  Notification of Rates. Each Reference Lender and Swing Line
                  Lender (if it is not the same Person as the Agent) shall
                  promptly notify the Agent of each interest rate that is
                  required to determine any rate of interest pursuant to this
                  Agreement. Promptly following receipt of each such

                                    - 108 -
<PAGE>

                  notice,or promptly after determination if the Agent and the
                  Reference Lender or Swing Line Lender is the same Person, the
                  Agent shall promptly notify the Lenders of each interest rate
                  the Agent is required to determine and report to the Lenders
                  pursuant to this Agreement.

13.20. Interlender Procedure for Making Advances

        13.20.1.  Subject to the terms and conditions of this Agreement, each
                  Credit Facility shall be available to the Relevant Borrower as
                  follows: upon receipt by the Agent of a Borrowing Request, the
                  Agent will promptly notify each Lender of the Agent's receipt
                  of such notice and of such Lender's Rateable Share of such
                  Borrowing. In the case of an issue of Bankers' Acceptances,
                  the Agent will round allocations amongst the Lenders to ensure
                  that each Bankers' Acceptance issued has a face amount which
                  is a whole number multiple of Cdn.$100,000 (and such rounded
                  allocations shall constitute the Lenders' respective Rateable
                  Shares for the purposes of this Agreement). Each Lender will
                  make its Rateable Share of each Borrowing or its Acceptance
                  Proceeds available to the Agent by paying, no later than 11:00
                  a.m. (Toronto time) on the Borrowing Date requested by the
                  Borrower, its Rateable Share of such Advance or such
                  Acceptance Proceeds to the Agent's Accounts. The Agent will
                  make such funds available, upon receipt, to the Relevant
                  Borrower on the Borrowing Date by bank transfer to the
                  Relevant Borrower's Accounts.

        13.20.2.  The obligations of the Agent under this Section 13.20 shall be
                  limited to taking such steps as are commercially reasonable to
                  implement the instructions described in Subsection 13.20.1,
                  and the Agent shall not be liable for any losses and expenses
                  which may be incurred or suffered by the Relevant Borrower and
                  occasioned by the failure or delay of funds to reach the
                  designated destination.

        13.20.3.  Unless the Agent has been notified by a Lender within two
                  Banking Days prior to the Borrowing Date requested by a
                  Borrower that such Lender will not make available to the Agent
                  its Rateable Share of such Borrowing or its Acceptance
                  Proceeds, the Agent may assume that such Lender has made such
                  portion of the Borrowing or such Acceptance Proceeds available
                  to the Agent on the Borrowing Date in accordance with the
                  provisions hereof, and the Agent may, in reliance upon such
                  assumption, make available (to the extent applicable) to the
                  Relevant Borrower on such date a corresponding amount. If the
                  Agent has made such assumption, to the extent a Lender has not
                  so made its Rateable Share of the Borrowing or its Acceptance
                  Proceeds available to the Agent, such Lender agrees to pay to
                  the Agent forthwith on demand, to the extent that such amount
                  is not
<PAGE>
                                    - 109 -


                  recovered from the Relevant Borrower within seven days of
                  demand (without in any way obligating the Agent to take legal
                  action with respect to such collection), such Lender's
                  Rateable Share of the Borrowing or its Acceptance Proceeds and
                  all losses and expenses incurred by the Agent in connection
                  therewith together with interest thereon (at the rate payable
                  hereunder by the Relevant Borrower in respect of such
                  Borrowing or at the rate per annum equivalent to the one month
                  CDOR BA Rate plus the applicable Stamping Fee which would
                  otherwise have been applicable to such Bankers' Acceptances)
                  for each day from the date such amount is made available by
                  the Agent until the date such amount is paid or repaid to the
                  Agent.

        13.20.4.  Notwithstanding Subsection 13.20.3, if a Lender fails so to
                  pay any portion of any Borrowing or its Acceptance Proceeds to
                  the Agent pursuant to Subsection 13.20.3, the Relevant
                  Borrower shall, without prejudice to any rights that the
                  Borrower might have against such Lender, repay such amount to
                  the Agent within three Banking Days after demand therefor by
                  the Agent.

        13.20.5.  Any amount payable to the Agent pursuant to this Section 13.20
                  (other than Section 13.20.1) shall be set forth in a
                  certificate delivered by the Agent to the Lender concerned and
                  Gerdau Steel (which certificate shall contain reasonable
                  details of how the amount payable is calculated) and shall be
                  prima facie evidence thereof. If a Lender makes the payment to
                  the Agent required by this Section 13.20, the amount so paid
                  shall constitute such Lender's Rateable Share of the Borrowing
                  or its Acceptance Proceeds for purposes of this Agreement.

        13.20.6.  The failure of any Lender to make its Rateable Share of any
                  Borrowing or its Acceptance Proceeds shall not relieve any
                  other Lender of its obligations, if any, hereunder to make its
                  Rateable Share of the Borrowing or its Acceptance Proceeds on
                  the Borrowing Date, but no Lender shall be responsible for the
                  failure of any other Lender to make available its Rateable
                  Share of any Borrowing or its Acceptance Proceeds to be made
                  available by such other Lender on any Borrowing Date.

13.21. Remittance of Payments

            Forthwith after receipt of any payment of principal, interest, fees
or other amounts for the benefit of the Lenders pursuant to the provisions
hereof, the Agent shall remit to each Lender, its Rateable Share of such
payment. If the Agent, on the assumption that it will receive, on any particular
date, a payment of principal, interest, fees or other amounts hereunder, remits
to each Lender its Rateable Share of such payment and the Relevant Borrower

payment, each Lender agrees to repay to the Agent forthwith on demand, to the
extent that such amount is not recovered from the Relevant Borrower within seven
days of demand (without in any way obligating the Agent to take any legal action
with respect to such collection), such Lender's Rateable Share of the payment
made pursuant hereto together with all losses and expenses incurred by the Agent
in connection therewith and interest thereon (at the rate payable hereunder by
the Relevant Borrower in respect of such amount) for each day from the date such
amount is remitted to the Lenders. The exact amount of the repayment required to
be made by the Lenders will be set forth in a certificate delivered by the Agent
to each Lender, which certificate shall be conclusive and binding for all
purposes, absent manifest error.

13.22. Redistribution of Payments

        13.22.1.  If any Lender shall exercise any right of counter-claim,
                  set-off or bankers' lien or similar right with respect to the
                  property of a Gerdau Canada Group Member or if under any
                  applicable bankruptcy, insolvency or other similar law it
                  receives a secured claim the security for which is a debt owed
                  by it to such Gerdau Canada Group Member, it shall apportion
                  the amount thereof proportionately between:

                  13.22.1.1.    amounts comprised in the Loan Obligations owing
                                to such Lender, which amounts shall be applied
                                in accordance with this Agreement; and

                  13.22.1.2.    amounts otherwise owed to it by such Gerdau
                                Canada Group Member;

                  provided that any cash collateral account funded by way of
                  advances from a Gerdau Canada Group Member as collateral for a
                  documentary or standby credit or letter of guarantee issued by
                  such Lender on behalf of such Gerdau Canada Group Member may
                  be applied by such Lender to such amounts owed by such Gerdau
                  Canada Group Member to such Lender in respect of any such
                  documentary or standby credit or letter of guarantee without
                  apportionment.

        13.22.2.  If a Lender shall, through the exercise of a right, or the
                  receipt of a secured claim described above or otherwise
                  receives payment of a portion of the Loan Obligations due to
                  it which is greater than the proportion received by any other
                  Lender in respect of the aggregate amount of the Loan
                  Obligations due to such other Lender (having regard to the
                  respective Rateable Shares of the Lenders), the Lender
                  receiving such proportionately greater payment shall purchase
                  a participation (which shall be done simultaneously with
                  receipt of such payment) in that portion of the Loan
                  Obligations due to the other Lender or Lenders (the
<PAGE>
                                    - 111 -


                  "Selling Lender or Lenders") so that the respective receipts
                  shall be pro rata according to their Rateable Shares;
                  provided, however, that if all or part of such proportionately
                  greater payment received by such purchasing Lender shall be
                  recovered from the Gerdau Canada Group Member by the Selling
                  Lender or Lenders, such purchase shall be rescinded and the
                  purchase price paid for such participation shall be returned
                  by such Selling Lender or Lenders to the extent of such
                  recovery, but without interest. Such Lender shall exercise its
                  rights in respect of such secured claim in a manner consistent
                  with the rights of the Lenders entitled under this Section
                  13.22 to share in the benefits of any recovery on such secured
                  claims.

        13.22.3.  If any Lender does any act or thing permitted by Subsections
                  13.22.1 or 13.22.2, it shall promptly provide full particulars
                  thereof to the Agent and the Agent shall promptly provide
                  copies of such particulars to the other Lenders.

13.23. Prompt Notice to Lenders

            The Agent agrees to provide to the Lenders copies of the
information, notices and reports received by it pursuant to Section 11.1.1.10
promptly upon receipt of same.

13.24. Several Debts of the Lenders

            Each Lender's share in each Borrowing constitutes a several debt
owing by the Relevant Borrower to such Lender.

13.25. Enforcement of Security

            Subject to the Security Coordination Agreement listed in Schedule L,
to the extent that the Agent receives or recovers monies pursuant to any right
of enforcement under the Security, such monies shall (without prejudice to the
rights of the Agent to credit any monies received by it to the Cash Collateral
Account), be applied as among the Syndicate:

        13.25.1.  first, in or towards payment of all of the Agent's losses and
                  expenses and disbursements;

        13.25.2.  secondly, in or towards payment of all amounts which are due
                  and payable at such time by each Borrower to the Lenders on
                  account of the Loan Obligations owing by such Borrower pro
                  rata to the respective aggregate amounts owing to the Lenders;

        13.25.3.  thirdly, if the Loan Obligations have been paid in full, in
                  payment to any Person to whom the Agent is obliged to pay in
                  priority to the Gerdau
<PAGE>
                                    - 112 -


                  Canada Group Member otherwise entitled thereto, to the extent
                  it is so obliged; and

        13.25.4.  fourthly, thereafter, in payment of the Gerdau Canada Group
                  Member entitled thereto.

The fact that the Agent may make a payment pursuant to paragraph 13.25.3 or
13.25.4 above or may determine that the Loan Obligations have been paid in full,
will not thereafter prevent the Agent from applying any further monies, or any
credit balance on any account, in the order set out in this Section 13.25.

13.26. Swing Line Loans

        13.26.1.  Unless the Swing Line Lender and the Majority Lenders agree
                  otherwise, if an Event of Default occurs then the Swing Line
                  Lender will promptly request the Agent on behalf of each
                  Relevant Borrower (and for this purpose the Swing Line Lender
                  is irrevocably authorized by each Relevant Borrower to do so)
                  for an Advance by way of Prime Rate Loan or Base Rate Loan (as
                  applicable) from the Lenders pursuant to Section 2.4 to repay
                  to the Swing Line Lender the Swing Line Loans. The Lenders are
                  irrevocably directed by each Relevant Borrower to make any
                  Advance by way of Prime Rate Loan or Base Rate Loan (as
                  applicable) if so requested by the Swing Line Lender and pay
                  the proceeds thereof directly to the Swing Line Lender. At all
                  times thereafter the Swing Line Commitment shall be treated as
                  reduced to nil, the Swing Line Lender's Revolver Commitment
                  shall be increased by the amount of such reduction and the
                  Lenders shall make such adjusting payments amongst them in the
                  manner contemplated by Section 13.22.2 as may be required to
                  ensure their respective participations in outstanding Advances
                  under the Revolver Facility reflect their respective Rateable
                  Portions of the Revolver Facility. If any Standby Instrument
                  is thereafter drawn upon which results in a further Swing Line
                  Loan the Swing Line Lender will again promptly request the
                  Agent on behalf of the Relevant Borrower (and for this purpose
                  the Swing Line Lender is irrevocably authorized by the
                  Relevant Borrower to do so) for an Advance by way of Prime
                  Rate Loan or Base Rate Loan (as applicable) from the Lenders
                  pursuant to Section 2.4 to repay that Swing Line Loan and the
                  foregoing provisions of this Subsection 13.26.1 shall equally
                  apply to each such further Advance. Each Lender
                  unconditionally agrees to pay to the Agent for the account of
                  the Swing Line Lender such Lender's Rateable Portion of each
                  Advance requested by the Swing Line Lender on behalf of the
                  Relevant Borrower to repay Swing Line Loans made by such Swing
                  Line Lender.

        13.26.2.  Except as provided in Subsection 13.26.4, the obligations of
                  each Lender under Subsection 13.26.1 are unconditional, shall
                  not be subject to any qualification or exception whatsoever
                  and shall be performed in accordance with the terms and
                  conditions of this Agreement under all circumstances
                  including:

                  13.26.2.1.    any lack of validity or enforceability of the
                                Relevant Borrower's obligations under Section
                                2.6 or Article Six;

                  13.26.2.2.    any of the matters referred to in Section 6.2 or
                                6.3;

                  13.26.2.3.    the occurrence of any Default or Event of
                                Default or the exercise of any rights by the
                                Agent under Section 13.2; and

                  13.26.2.4.    the absence of any demand for payment being
                                made, any proof of claim being filed, any
                                Security being enforced, any proceeding being
                                commenced or any judgment being obtained by the
                                Swing Line Lender or the Issuing Bank against
                                the Relevant Borrower.

        13.26.3.  If a Lender (a "Defaulting Lender") fails to make payment on
                  the due date therefor of any amount due from it for the
                  account of the Swing Line Lender pursuant to Subsection
                  13.26.1 (the balance thereof for the time being unpaid being
                  referred to in this Subsection 13.26.3 as an "overdue amount")
                  then until the Swing Line Lender has received payment of that
                  amount (plus interest as provided below) in full (and without
                  in any way limiting the rights of the Swing Line Lender in
                  respect of such failure):

                  13.26.3.1.    the Swing Line Lender shall be entitled to
                                receive any payment which the Defaulting Lender
                                would otherwise have been entitled to receive in
                                respect of the Credit Facilities or otherwise in
                                respect of any Loan Document; and

                  13.26.3.2.    the overdue amount shall bear interest payable
                                by the Defaulting Lender to the Swing Line
                                Lender at the rate payable by the Relevant
                                Borrower in respect of the Loan Obligations
                                which gave rise to such overdue amount.

        13.26.4.  If for any reason an Advance may not be made pursuant to
                  Subsection 13.26.1 to reimburse the Swing Line Lender as
                  contemplated thereby, then promptly upon receipt of
                  notification of such fact from the Agent, each Lender shall
                  deliver to the Agent for the account of such Swing Line Lender
                  in immediately available funds the purchase price for
<PAGE>
                                    - 114 -


                  such Lender's participation interest in the relevant
                  unreimbursed Swing Line Advances. Each Lender shall, upon
                  demand by such Swing Line Lender made to the Agent, deliver to
                  the Agent for the account of such Swing Line Lender interest
                  on such Lender's Rateable Share from the date of payment by
                  such Swing Line Lender of such unreimbursed Swing Line
                  Advances until the date of delivery of such funds to such
                  Swing Line Lender by such Lender at a rate per annum equal to
                  the Federal Funds Rate (in the case reimbursement is to be
                  made in U.S. Dollars) or the one month CDOR BA Rate (in the
                  case the reimbursement is to be made in Canadian Dollars) for
                  such period. Such payment shall only, however, be made by the
                  Lenders in the event and to the extent such Swing Line Lender
                  has not been reimbursed in full by the Relevant Borrower for
                  interest on the amount of such unreimbursed Swing Line
                  Obligations.

        13.26.5.  The Swing Line Lender shall, forthwith upon its receipt of any
                  reimbursement (in whole or in part) by the Relevant Borrower
                  for any unreimbursed Swing Line Advances in relation to which
                  other Lenders have purchased a participation interest pursuant
                  to Subsection 13.26.4, or of any other amount from the
                  Relevant Borrower or any other Person in respect of such
                  payment (other than pursuant to Section 2.6 or 6.2), transfer
                  to such other Lender such other Lender's Rateable Share of
                  such reimbursement or other amount. In the event that any
                  receipt by the Issuing Bank of any reimbursement or other
                  amount is found to have been a transfer in fraud of creditors
                  or a preferential payment under any applicable insolvency
                  legislation or is otherwise required to be returned, such
                  Lender shall promptly return to such Swing Line Lender any
                  portion thereof previously transferred to it by such Swing
                  Line Lender, without interest to the extent that interest is
                  not payable by such Swing Line Lender in connection therewith.

                                   ARTICLE 14.
                                     GENERAL

14.1. Reliance and Non-Merger

            All covenants, agreements, representations and warranties of each
party hereto (other than the Lenders) made herein or in any other Loan Document
or in any certificate or other document signed by any of its directors or
officers and delivered by or on behalf of it pursuant hereto or thereto are
material, shall be deemed to have been relied upon by the Syndicate
notwithstanding any investigation heretofore or hereafter made by the Syndicate
or the Lenders' Counsel or any employee, agent or other representative of any of
the Syndicate and shall survive
<PAGE>
                                    - 115 -


the execution and delivery of this Agreement and the other Loan Documents until
the Borrowers shall have satisfied and performed all of the Loan Obligations.


14.2. Amendment and Waiver

            No amendment of any provision of any Loan Document or consent to any
departure by any other party thereto from any provision thereof is effective
unless it is in writing and signed by the Required Lenders. No amendment of or
consent to any departure from any provision of any Loan Document to which any
party hereto (other than a Lender) is party shall require the agreement of any
other party hereto, except the Required Lenders, to be effective and binding on
all parties hereto. Such amendment or consent shall be effective only in the
specific instance and for the specific purpose for which it is given. No failure
or delay on the part of the Syndicate in exercising any right under any Loan
Document or under any other instrument delivered to any Lender pursuant thereto
and no indulgence or forbearance by any of the Syndicate in respect of the
strict application of the provisions thereof shall operate as a waiver unless
made in writing and signed by an officer of the Agent in accordance with Section
13.18. Any written waiver by the Syndicate shall not preclude the further
exercise by the Syndicate of any right hereunder or extend to or apply to any
subsequent default of the same or any other nature.


14.3. Set-Off or Compensation

            In addition to and not in limitation of any rights now or hereafter
granted under Applicable Law, but subject to Section 13.22, if a Default or
Event of Default has occurred or is continuing, each Lender, may at any time and
from time to time without prior notice to any other party hereto or any other
Person, any such prior notice being expressly waived by each such party hereto,
combine, off-set, set-off or compensate and apply any and all deposits, general
or special, time or demand, provisional or final, matured or unmatured, in the
same or in different currencies, and any other indebtedness at any time owing by
the Lender, to or for the credit of or for the account of either Borrower,
against and on account of that Borrower's Loan Obligations notwithstanding that
any of them are contingent or unmatured and notwithstanding that any such
deposit or indebtedness may or may not be expressed in the same Currency.


14.4. Notices

            Any notice or other communication required or permitted to be given
hereunder shall be in writing and shall be given by prepaid first-class mail, by
telecopier or other means of electronic communication or by hand-delivery as
hereinafter provided. Any such notice, if mailed by prepaid first-class mail at
any time other than during or within three Banking Days prior to a general
discontinuance of postal service due to strike, lockout or otherwise, shall be
deemed to have been received on the fourth Banking Day after the post-marked
date thereof, or if
<PAGE>
                                    - 116 -


sent by telecopier or other means of electronic communication, shall be deemed
to have been received on the Banking Day following the sending, or if delivered
by hand shall be deemed to have been received at the time it is delivered to the
applicable address of the addressee either to the individual designated in
Schedule A or F, as applicable, or to a senior employee of the addressee at such
address (and, in the case of any Lender, at the same department within the
Lender) with responsibility for matters to which the information relates. Notice
of change of address shall also be governed by this Section 14.4. In the event
of a general discontinuance of postal service due to strike, lock-out or
otherwise, notices or other communications shall be delivered by hand or sent by
facsimile or other means of electronic communication and shall be deemed to have
been received in accordance with this Section 14.4. Notwithstanding the
foregoing, no notice or other communication to the Agent or (so long as they are
the same Person) the Agent shall be effective or be deemed to be received by the
Agent or (so long as they are the same Person) the Agent unless it is sent by
telecopier or delivered by hand. Notices and other communications shall be
addressed to the addresses of the relevant party hereto specified beside its
name on Schedule A or F, as applicable.


14.5. Binding Effect and Assignment

        14.5.1.   Benefit & Burden. The Loan Documents shall enure to the
                  benefit of and be binding on the parties hereto, their
                  respective successors and each assignee of some or all of the
                  rights or obligations of the parties under the Loan Documents
                  permitted by Subsection 14.5.4. Any reference in any such Loan
                  Document to any party shall (to the extent the context so
                  admits) be construed accordingly.

        14.5.2.   Borrower. No Borrower may assign all or any part of any of its
                  rights or obligations in respect of any Credit Facility or
                  under any Loan Document. Where the context so admits, each
                  reference in this Agreement to any Borrower shall be construed
                  so as to include the successors of such Borrower.

        14.5.3.   Participation. Each Lender may grant a participation in the
                  whole or any part of its Revolver Commitment or Term
                  Commitment (including its share in any Advances made by it
                  hereunder) to any other Person (a "Participant") provided
                  that, in respect of such share of its Revolver Commitment or
                  Term Commitment and as amongst all parties to this Agreement,
                  such Lender shall remain entitled to all rights, and shall
                  remain responsible for the performance of all obligations, of
                  such Lender under this Agreement with respect to the share of
                  its Revolver Commitment or Term Commitment subject to such
                  participation.

        14.5.4.   Assignments. Each Lender (a "Transferring Lender") may assign
                  its Revolver Commitment or Term Commitment (including its
                  share in any

                                    - 117 -


                  Advances made hereunder), or any part thereof in a minimum
                  amount of Cdn.$10,000,000 to (i) any Person during the period
                  of primary syndication of the Credit Facilities, (ii) any
                  affiliate of the Transferring Lender, (iii) prior to the
                  occurrence of an Event of Default, to any Person not referred
                  to in clauses (i) and (ii), with the prior consent of the
                  Agent and the Borrowers, such consent not to be unreasonably
                  withheld or delayed or (iv) after the occurrence of an Event
                  of Default, to any other Person without the consent of any
                  other party hereto, other than the Agent whose consent shall
                  still be required and which will not be unreasonably withheld
                  or delayed. Any such transfer to any Person permitted pursuant
                  to the preceding sentence (a "Transferee") shall be made
                  pursuant to a loan transfer agreement (a "Loan Transfer
                  Agreement") substantially in the form of Schedule H (or in
                  such other form to similar effect as the Agent may approve).
                  Each Loan Transfer Agreement must be delivered to the Agent at
                  least five Banking Days before it takes effect accompanied, if
                  such assignment is not being made to an affiliate of an
                  existing Lender and is not being made during the period of
                  primary syndication of the Credit Facilities, by payment to
                  the Agent of a processing fee of Cdn.$3,500. Each party hereto
                  hereby agrees that any such Transferee under any such Loan
                  Transfer Agreement shall be entitled to rights identical to
                  the rights assigned to such Transferee as if such Transferee
                  were named in this Agreement as an original party in
                  substitution for the Transferring Lender in respect of such
                  Revolver Commitment and Term Commitment, or part thereof,
                  assigned, and such Transferring Lender shall be released from
                  all obligations in relation to its Revolver Commitment and
                  Term Commitment, or part thereof, so assigned.

        14.5.5.   Schedule A Revisions: The Agent shall from time to time revise
                  Schedule A to record the Lenders and their respective
                  Commitments and Lending Offices after giving effect to
                  assignments and changes in Lending Offices referred to above.
                  Any such revised Schedule A shall be prima facie evidence of
                  the identities, Commitments and Lending Offices of the
                  Lenders. The Agent shall provide a copy of any revised
                  Schedule A to the Borrowers or any Lender upon request.

14.6. Confidentiality

            Each Lender shall, subject as hereinafter provided, keep
confidential from any third party (excluding directors, officers, employees,
agents, solicitors, accountants, consultants, financial advisors and all other
representatives of the Lender) any data or information received by it from a
Borrower pursuant to this Agreement which is confidential or which is designated
in writing as such by a Borrower except to the extent that such information was
not confidential when received by the Lender, except as required by law, rule,
regulation or official directive or as
<PAGE>
                                    - 118 -


may be necessary to protect the interests of any Lender under this Agreement.
Notwithstanding any other provision of this Section 14.6, any Lender may make
available any confidential data or information received by it pursuant to this
Agreement:

        14.6.1.   to any other Lender;

        14.6.2.   to any Person referred to in Section 14.5 to whom the Lender
                  is soliciting to purchase or has granted a participation or
                  assignment of the whole or any part of any of the Lender's
                  rights or obligations under this Agreement so long as that
                  Person agrees with the Lender to be bound by the same
                  conditions and obligations pertaining to confidentiality which
                  apply to the Lender under this Section 14.6;

        14.6.3.   to any Person referred to in Section 13.15 to whom the Agent,
                  Agent or the Issuing Bank is soliciting to be a successor
                  agent, security trustee or issuing bank under this Agreement;
                  or

        14.6.4.   as may be necessary in connection with the enforcement of this
                  Agreement or any other Loan Document.

14.7. Time

            Time is of the essence of each of the Loan Documents.

14.8. Further Assurances

            Whether before or after the happening of a Default or an Event of
Default, each Obligor party hereto shall at its own expense do, make, execute or
deliver all such further acts, documents and things in connection with the Loans
and the Loan Documents as the Agent may reasonably require from time to time for
the purpose of giving effect to the Loan Documents including for the purpose of
facilitating the enforcement of the Security, all immediately upon the request
of the Agent.

14.9. Currency Conversion and Indemnity

        14.9.1.   All payments made hereunder shall be made in the Currency in
                  respect of which the Loan Obligations requiring such payment
                  arose. If, in connection with any action or proceeding brought
                  in connection with this Agreement or any other of the Loan
                  Documents or any judgment or order obtained as a result
                  thereof, it becomes necessary to convert any amount due
                  hereunder in one Currency (the "first Currency") into another
                  Currency (the "second Currency"), then the
<PAGE>
                                    - 119 -


                  conversion shall be made at the Spot Rate on the first Banking
                  Day prior to the day on which payment is received.

        14.9.2.   If the conversion is not able to be made in the manner
                  contemplated by subsection 14.9.1 in the jurisdiction in which
                  the action or proceeding is brought, then the conversion shall
                  be made at the Spot Rate on the day on which the judgment is
                  given.

        14.9.3.   If the Spot Rate on the date of payment is different from the
                  Spot Rate on such first Banking Day or on the date of
                  judgment, as the case may be, the Borrower concerned shall pay
                  such additional amount (if any) in the second Currency as may
                  be necessary to ensure that the amount paid on such payment
                  date is the aggregate amount in the second Currency which,
                  when converted at the Spot Rate on the date of payment, is the
                  amount due in the first Currency, together with all costs,
                  charges and expenses of conversion. Any additional amount
                  owing by a Borrower to any Lender pursuant to the provisions
                  of this Section 14.9 shall be due as a separate debt and shall
                  give rise to a separate cause of action and shall not be
                  affected by or merged into any judgment obtained for any other
                  amounts due under or in respect of this Agreement or any other
                  of the Loan Documents.

14.10. Taxes

        14.10.1.  Each payment under each Loan Document shall be made without
                  any deduction or withholding for or on account of any Tax
                  unless such deduction or withholding is required by any
                  Applicable Law, as modified by the practice of any relevant
                  Governmental Body, then in effect. If the Relevant Borrower is
                  required to deduct or withhold Tax from any such payment to
                  any Lender (the "Affected Lender"), then the Relevant Borrower
                  will:

                  14.10.1.1.    promptly notify the Agent of such requirement;

                  14.10.1.2.    pay to the relevant Governmental Body the full
                                amount required to be deducted or withheld
                                (including the full amount required to be
                                deducted or withheld from any additional amount
                                paid by the Relevant Borrower to the Affected
                                Lender under this Subsection 14.10.1) promptly
                                upon the earlier of determining that such
                                deduction or withholding is required or
                                receiving notice that such amount has been
                                assessed against the Relevant Borrower;

                  14.10.1.3.    promptly forward to the Agent an official
                                receipt (or a certified copy), or other
                                documentation reasonably acceptable to the
<PAGE>
                                    - 120 -


                                Agent, evidencing such payment to such
                                Governmental Body; and

                  14.10.1.4.    pay to the Affected Lender, in addition to the
                                payment to which the Affected Lender is
                                otherwise entitled under such Loan Document such
                                additional amount as is necessary to ensure that
                                the net amount actually received by the Affected
                                Lender (free and clear of Tax, whether assessed
                                against the Relevant Borrower or the Affected
                                Lender) will equal the full amount the Affected
                                Lender would have received had no such deduction
                                or withholding been required.

        14.10.2.  If an Affected Lender is, in its sole opinion, entitled to
                  claim a refund or able to apply for or otherwise take
                  advantage of any tax credit, tax deduction or similar benefit
                  by reason of any withholding or deduction made by a Relevant
                  Borrower in respect of a payment made by it hereunder which
                  payment shall have been increased pursuant to Subsection
                  14.10.1, then such Affected Lender will use commercially
                  reasonable efforts (to the extent it has the administrative
                  controls in place to enable it to do so) to obtain such
                  refund, credit, deduction or benefit and upon receipt thereof
                  will pay to the Relevant Borrower such amount (if any) not
                  exceeding the increased amount paid by the Relevant Borrower
                  as equals the net after tax value to such Affected Lender of
                  such part of such refund, credit, deduction or benefit as it
                  considers is allocable to such withholding or deduction having
                  regard to all its dealings giving rise to similar credits,
                  deductions or benefits in relation to the same tax period and
                  to the cost of obtaining the same, provided that nothing
                  herein shall (i) interfere with the right of any Affected
                  Lender to arrange its tax affairs in whatever manner it deems
                  fit and in particular no Affected Lender shall be under any
                  obligation to claim relief from its corporate profits or
                  similar tax liability in respect to any such deduction or
                  withholding in priority to any other relief, claims, credits
                  or deductions available to it and (ii) no Affected Lender
                  shall be obligated to disclose to any Relevant Borrower any
                  information regarding its tax affairs or tax computations.

14.11. Joint Arrangers and Joint Bookrunners and Co-Syndication Agents

            None of the Joint Arrangers and Joint Bookrunners, Co-Syndication

        14.11.1.  to any Gerdau S.A. Group Member as a consequence of any

                  Lender of any of its obligations under any Loan Document;

        14.11.2.  to any Lender as a consequence of any failure or delay in

                  of any of its obligations under any Loan Document; or

        14.11.3.  to any Lender for any statements, representations or
                  warranties in any Loan Document or any other agreement,
                  document or instrument contemplated by any Loan Document or
                  any other information provided pursuant to any Loan Document
                  or any other agreement, document or instrument contemplated by

                  enforceability or sufficiency of any Loan Document or any
                  other agreement, document or instrument contemplated thereby.

one to the other, the receipt and sufficiency of which are hereby acknowledged,
the parties hereto agree as follows:

1. Transferred Commitment

            The Transferor confirms to each of the Transferee and the other
parties to the Loan Agreement that the Transferred Commitment relates to the
Revolver Transfer Percentage of its Revolver Commitment and the Term Transfer
Percentage of its Term Commitment (including the corresponding percentage of
each outstanding Loan under each such portion of its Commitment) represented as
of the date hereof as set out in Appendix 1 to this loan transfer agreement.

2. Transfer

            As of and from ____________, _______ (herein called the "Effective
Date") and subject to the terms and conditions herein contained:

      (a)   the Transferee assumes obligations identical to the obligations of
            the Transferor under the Loan Agreement arising on or after the
            Effective Date in relation to the Transferred Commitment (herein
            called the "Transferred Obligations") and agrees to perform and be
            responsible for such obligations as if the Transferee were named in
            the Loan Agreement as an original party in substitution for the
            Transferor or its predecessor in title, as applicable, in respect of
            the Transferred Obligations;

      (b)   the Agent on behalf of each of the Lenders other than the Transferor
            (herein called the "Other Lenders") hereby releases and forever

            expenses and obligations arising on or after the Effective Date
            under, by reason of, or in connection with the Transferred
            Obligations;

      (c)   the Agent on behalf of each of the Other Lenders acknowledges and
            agrees that, except as otherwise provided in section 3 of this loan
            transfer agreement, the Transferee is entitled to rights identical
            to the rights of the Transferor under the Loan Agreement existing on
            or arising after the Effective Date in relation to the Transferred
            Commitment (herein called the "Transferred Rights");

      (d)   the Transferor hereby releases and forever discharges each of the
            Other Lenders of and from any and all losses and expenses and
            obligations arising under, by reason of, or in connection with the
            Transferred Rights or the Transferred Obligations.

            Effective Date in respect of the Transferred Commitment; and

      (b)   any payments due and payable by the Borrowers after the Effective
            Date, but payable in respect of the Transferor's participation in
            any LIBOR Loan or issue of Bankers' Acceptances outstanding on the
            Effective Date,

shall, upon receipt by the Agent, be paid to the Transferor. For certainty, the
Transferee acknowledges that its participation in Loans outstanding under the
Credit Facilities as at the Effective Date is subject to the maturity of
existing contracts on their respective Maturity Dates (to the extent there are
Bankers' Acceptances and LIBOR Loans outstanding on the Effective Date), and
that the Transferor's participation in outstanding Loans will increase in
proportion to its Rateable Portion as such existing contracts mature.

provide a signed copy of this loan transfer agreement (without the attached
Appendices) to Courtice (to be received by Courtice for itself, MRM and the
Guarantors) in acceptance of the offer contained in the Loan Agreement of the
Borrowers and the Guarantors to the Transferee to become a party to the Loan
Agreement in respect of the Transferred Commitment. Upon receipt thereof by
Courtice, the provisions of Section 16.5.4 of the Loan Agreement in respect of
the Transferred Commitment shall become effective and be binding upon all
parties to the Loan Agreement.

5. Interpretation

      4. REPRESENTATIONS AND WARRANTIES.

      The Pledgor represents and warrants to the Agent and the Lenders that:

      4.1. Existence and Standing. The Pledgor is duly organized and is validly
existing and in good standing under the laws of its jurisdiction of
incorporation, and the Pledgor has all requisite authority to conduct its
business in each jurisdiction in which its business is conducted.

      4.2. Authorization, Validity and Enforceability. The execution, delivery
and performance by the Pledgor of this Pledge Agreement has been duly authorized
by proper corporate proceedings, and this Pledge Agreement constitutes a legal,
valid and binding obligation of the Pledgor, enforceable against the Pledgor in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency or similar laws affecting the enforcement of creditors'
rights generally and subject also to the availability of equitable remedies if
equitable remedies are sought, and creates a security interest which is
enforceable against the Pledgor in all now owned and hereafter acquired
Collateral. No consent or approval of any Governmental Body which has not been
obtained is required in connection with the execution, delivery and performance
by the Pledgor of this Pledge Agreement.

      4.3. Conflicting Laws and Contracts. Neither the execution and delivery by
the Pledgor of this Pledge Agreement, nor the creation and perfection of the
security interest in the Collateral granted hereunder, nor compliance by the
Pledgor with the terms and provisions hereof will violate any law, rule,
regulation, order, writ, judgment, injunction, decree or award binding on the
Pledgor or the Pledgor's articles of incorporation or by-laws, the provisions of
any indenture, instrument or agreement to which the Pledgor is a party or is
subject, or by which it, or its property, is bound, or conflict with or
constitute a default thereunder, or result in the creation or imposition of any
Lien pursuant to the terms of any such indenture, instrument or agreement.

      4.4. No Default. No Default or Unmatured Default exists.

      4.5. Pledged Stock. The Pledgor is the direct and beneficial owner of each
share of the Pledged Stock and the Pledged Stock represents the percentage (on a
fully diluted basis) of the issued and outstanding capital stock of its issuer
as set forth on Schedule A hereto. All of the shares of the Pledged Stock are
duly authorized, validly issued, fully paid and non-assessable. Subject to the
restrictions contained in the Shareholders' Agreement (a true copy of which has
been provided by the Pledgor to the Agent prior to the execution hereof), the
Pledgor has good and marketable title to the Pledged Stock and has all requisite
rights, power, and authority to execute, deliver and comply with the terms of
this Pledge Agreement and to pledge and deliver


                                      -4-
<PAGE>

the Collateral to the Agent pursuant hereto. The Pledged Stock is free and clear
of all Liens, options, warrants, puts, calls, or other rights of third persons,
and restrictions, other than (i) those liens arising under this Pledge
Agreement, (ii) restrictions on transferability imposed by applicable state and
Federal securities laws, rules and regulations and (iii) the restrictions
contained in the Shareholders' Agreement. Assuming the Agent has possession of
the Pledged Stock, the pledge, assignment and delivery of the Pledged Stock
pursuant to this Pledge Agreement creates a valid, continuing, first perfected
Lien on the Pledged Stock in favor of the Agent, for the benefit of the Agent
and the Lenders, subject to no prior Lien of any other Person, other than
Permitted Liens referred to in clauses (i), (ii), (xviii) and (xix) of the
definition of "Permitted Liens" in the Loan Agreement.

      5. COVENANTS.

      From the date hereof and continuing thereafter until this Pledge Agreement
is terminated pursuant to Section 9.10, the Pledgor covenants and agrees with
the Agent and the Lenders as follows:

      5.1. Pledge of Additional Stock. If the Pledgor shall at any time acquire
any additional shares of the capital stock of any class of the Issuer, whether
such acquisition shall be by purchase, exchange, reclassification, dividend, or
otherwise, the Pledgor shall forthwith (and without the necessity for any
request or demand by the Agent or any Lender) deliver the certificates
representing such shares to the Agent, in the same manner as described in
Section 3. The Pledgor will hold in trust for the Agent and the Lenders upon
receipt and immediately thereafter deliver to the Agent any other instrument
evidencing or constituting Collateral (except, prior to the occurrence of an
Unmatured Default or a Default, ordinary cash dividends, if any, paid with
respect to the Pledged Stock and the Stock Rights and permitted by the Loan
Agreement).

      5.2. Applications, Approvals and Consents. The Pledgor will, at its
expense, promptly execute and deliver, or cause the execution and delivery by
the issuer of the Pledged Stock of, all applications, certificates, instruments,
registration statements, and all other documents and papers the Agent on behalf
of the Lenders may reasonably request in connection with the obtaining of any
consent, approval, registration, qualification, or authorization of any
Governmental Body necessary or appropriate for the effective exercise of any
rights under this Pledge Agreement. Upon the Pledgor's request therefor, the
Agent shall acknowledge in writing receipt of all such certificates, instruments
and other documents. Without limiting the generality of the foregoing, the
Pledgor agrees that in the event the Agent on behalf of the Lenders shall
exercise its right to sell, transfer, or otherwise dispose of or take any other
action in connection with any of the Collateral pursuant to this Pledge
Agreement, the Pledgor shall execute and deliver all applications, certificates,
and other documents the Agent may reasonably request and shall otherwise
promptly, fully and diligently cooperate with the Agent and any other necessary
Persons, in making any application for the prior consent or approval of any
relevant Governmental Body to the exercise by the Agent or the Lenders of any of
such rights relating to all or any part of the Collateral. Furthermore, because
the Pledgor agrees that the Lenders' remedy at law for failure of the Pledgor to
comply with the provisions of this Section 5.2 would


                                      -5-
<PAGE>

be inadequate and that such failure would not be adequately compensable in
damages, the Pledgor agrees that the covenants of this Section 5.2 may be
specifically enforced.

      5.3. Title; Security Interest and Lien. The Pledgor (a) will preserve,
warrant, and defend title to and ownership of the Pledged Stock and the Lien in
the Collateral created hereby against the claims of all Persons whomsoever; (b)
will not at any time assign, transfer, or otherwise dispose of its right, title
and interest in and to any of the Collateral; (c) will not do or suffer any
matter or thing whereby the Lien created by this Pledge Agreement in and to the
Collateral might or could be impaired; and (d) will not at any time, directly or
indirectly, create, assume, or suffer to exist any Lien, warrant, put, option,
or other rights of third Persons and restrictions in and to the Collateral or
any part thereof other than (i) those Liens arising under this Pledge Agreement,
(ii) restrictions on transferability imposed by applicable state and Federal
securities laws, rules and regulations, (iii) Permitted Liens referred to in
clauses (i), (ii), (xviii) and (xix) of the definition of that term in the Loan
Agreement, and (iv) the restrictions contained in the Shareholders' Agreement.

      5.4. Further Assurances. The Pledgor, at its expense, shall from time to
time execute and deliver to the Agent all such other assignments, certificates,
supplemental documents and financing statements, and do all other acts or things
as the Agent may reasonably request in order to more fully create, evidence,
perfect, continue and preserve the priority of the Lien created hereby. If so
requested by the Agent, the Pledgor shall cause the Pledged Stock to be
registered and recorded in the books, records and registers of the Issuer in the
name of the Agent or its nominee.

      5.5. Pledged Stock.

            5.5.1. Changes in Capital Structure of Issuers. The Pledgor will not
      (i) permit or suffer the Issuer to dissolve, liquidate, retire any of its
      capital stock, reduce its capital or merge or consolidate with any other
      entity, except for a merger permitted by Section 11.3 of the Loan
      Agreement, or (ii) vote any of the Pledged Stock in favor of any of the
      foregoing.

            5.5.2. Issuance of Additional Stock. The Pledgor will not permit or
      suffer the Issuer to issue any stock, any right to receive stock or any
      right to receive earnings, except to the Pledgor.

            5.5.3. Disposition of Collateral. The Pledgor will not sell or
      otherwise dispose of all or any part of the Collateral.

            5.5.4. Registration of Pledged Stock. After the occurrence of a
      Default, the Pledgor will, to the extent permitted by applicable law and
      to the extent not previously registered in the name of the Agent or its
      nominee under Section 5.4 above, permit any registerable Collateral to be
      registered in the name of the Agent or its nominee at any time at the
      option of the Required Lenders.

<PAGE>

            5.5.5. Exercise of Rights in Pledged Stock. The Pledgor will permit
      the Agent or its nominee at any time after the occurrence of a Default,
      without notice, to exercise all voting and corporate rights relating to
      the Collateral, including, without limitation, exchange, subscription or
      any other rights, privileges, or options pertaining to any shares of the
      Pledged Stock and the Stock Rights as if it were the absolute owner
      thereof.

      5.6. Notice of Default. The Pledgor will give prompt notice in writing to
the Agent and the Lenders of the occurrence of any Default or Unmatured Default
and of any other development, financial or otherwise, which might materially
adversely affect the Collateral.

      6. RIGHTS OF PLEDGOR, AGENT AND THE LENDERS.

      6.1. Default; Exercise of Stockholder Rights.

            (a) Unless and until an Unmatured Default or a Default shall occur
      and be continuing, the Pledgor shall be entitled to receive all cash
      dividends or other distributions on the Pledged Stock except (i)
      distributions made in capital stock on the Pledged Stock resulting from
      stock dividends or on subdivision, combination, or reclassification of the
      outstanding capital stock of any corporation or as a result of any merger,
      consolidation, acquisition or other exchange of assets of any corporation;
      and (ii) all sums paid on any Pledged Stock upon liquidation or
      dissolution or reduction of capital, repurchase, retirement or redemption.
      All such sums, dividends, distributions, proceeds or property described in
      the immediately preceding clauses (i) and (ii) shall, if received by any
      Person other than the Agent, be held in trust for the benefit of the Agent
      and the Lenders and shall forthwith be delivered to the Agent for the
      benefit of the Agent and the Lenders (accompanied by proper instruments of
      assignment and/or stock powers executed by the Pledgor in accordance with
      the Agent's instructions) to be held subject to the terms of this Pledge
      Agreement. Upon the occurrence of a Default, the Agent, for the benefit of
      the Agent and the Lenders, shall be entitled to receive all payments of
      whatever kind made upon or with respect to any Collateral and to hold such
      payments as Collateral or apply such payments pursuant to the terms of
      this Agreement and the Guaranty. As used herein, the term "Default" shall
      mean the occurrence of any one or more of the following events:

                  (A) Any representation or warranty made by or on behalf of the
            Pledgor to the Agent or the Lenders under or in connection with this
            Pledge Agreement or the Guaranty shall be materially false on the
            date as of which made.

                  (B) The breach by the Pledgor (other than a breach which
            constitutes a Default under Section 6.1(a)(A)) of any of the terms
            or provisions of this Pledge Agreement which is not remedied within
            15 Business Days after the Pledgor knows or should have known of
            such failure.

                  (C) The occurrence of any "Event of Default" under, and as
            defined in, the Loan Agreement.


                                      -7-
<PAGE>

            (b) Prior to the occurrence of a Default, the Pledgor shall have the
      sole and exclusive right to vote and give consents with respect to all of
      the Collateral and to consent to, ratify, or waive notice of any and all
      meetings. Upon the occurrence of a Default, the Agent, on behalf of the
      Lenders, shall have the right, but shall not be obligated, (A) to vote and
      give consents with respect to any Pledged Stock and, in connection
      therewith, to join in and become a party to any plan of recapitalization,
      reorganization, or readjustment (whether voluntary or involuntary) as
      shall seem desirable to the Agent, on behalf of the Lenders, to protect or
      further their interests in respect of the Collateral, (B) to deposit the
      Collateral under any such plan, and (C) to make any exchange,
      substitution, cancellation, or surrender of the Collateral required by any
      such plan and to take such action with respect to the Collateral as may be
      required by any such plan or for the accomplishment thereof, and no such
      disposition, exchange, substitution, cancellation, or surrender shall be
      deemed to constitute a release of the Collateral from the Lien of this
      Pledge Agreement.

      6.2. Right of Sale after Default. Upon the occurrence and during the
continuance of a Default, the Agent on behalf of the Lenders may exercise any or
all of the rights and remedies provided (i) in this Pledge Agreement, (ii) to a
secured party when a debtor is in default under a security agreement by the New
York Uniform Commercial Code and (iii) by any other applicable law including,
without limitation, any law governing the exercise of a bank's right of setoff
or bankers' lien. Without limiting the generality of the foregoing, upon the
occurrence and continuance of a Default, the Agent may sell, without recourse to
judicial proceedings, with the right to bid for and buy, free from any right of
redemption, the Collateral or any part thereof, upon ten days' notice (which
notice is agreed to be reasonable notice for the purposes hereof) to the Pledgor
of the time and place of sale, for cash, upon credit or for future delivery, at
the Lenders' option and in the Lenders' complete discretion:

            (a) At public sale, including a sale at any broker's board or
      exchange;

            (b) At private sale in any commercially reasonable manner which will
      not require the Collateral, or any part thereof, to be registered in
      accordance with the Securities Act of 1933, as amended, or the rules and
      regulations promulgated thereunder, or any other law or regulation. The
      Agent and the Lenders are also hereby authorized, but not obligated, to
      take such actions, give such notices, obtain such consents, and do such
      other things as they may deem required or appropriate in the event of sale
      or disposition of any of the Collateral. The Pledgor understands that the
      Agent, on behalf of the Lenders, may in its discretion approach a
      restricted number of potential purchasers and that a sale under such
      circumstances may yield a lower price for the Collateral, or any portion
      thereof, than would otherwise be obtainable if the same were registered
      and sold in the open market. The Pledgor agrees that (i) in the event the
      Agent shall so sell the Collateral, or any portion thereof, at such
      private sale or sales, the Agent and the Lenders shall have the right to
      rely upon the advice and opinion of any Person with whom the Lenders deal
      at arm's length who regularly deals in or evaluates stock of the type
      constituting the Collateral as to the price obtainable in a commercially
      reasonable manner


                                      -8-
<PAGE>

      upon such a private sale thereof, and (ii) such reliance shall be
      conclusive evidence that the Agent and the Lenders handled such matter in
      a commercially reasonable manner.

      In the case of any sale by the Agent on behalf of the Lenders of the
Collateral on credit or for future delivery, the Collateral sold may be retained
by the Agent until the selling price is paid by the purchaser, but neither the
Agent nor any Lender shall incur liability in case of failure of the purchaser
to take up and pay for the Collateral so sold.

      In the event that the Agent and the Lenders reasonably determine that a
private sale is not economically practical, and if in the opinion of the Agent
and the Lenders it is necessary or advisable to have such securities registered
under the provisions of such Act, or any similar law relating to the
registration of securities, the Pledgor agrees, at its own expense, to (i)
execute and deliver all such instruments and documents, and do or cause to be
done such other acts and things, as may be necessary or, in the opinion of the
Agent, advisable to register such securities under the provisions of such Act or
any applicable similar law relating to the registration of securities, and the
Pledgor will use its best efforts to cause the registration statement relating
thereto to become effective and to remain effective for such period as the Agent
shall request, and to make all amendments thereto and/or to the related
prospectus which, in the opinion of the Agent, are necessary or desirable, all
in conformity with the requirements of such Act and the rules and regulations of
the Securities and Exchange Commission applicable thereto; (ii) use its best
efforts to qualify such securities under state "blue sky" or securities laws,
all as reasonably requested by the Agent; and (iii) at the request of the Agent,
indemnify and hold harmless the Lenders, the Agent, any underwriters (and any
Person controlling any of the foregoing), and their respective employees,
officers, agents, attorneys, and accountants (collectively, the "Indemnified
Parties") from and against any loss, liability, claim, damage, and expense
(including, without limitation, fees of counsel incurred in connection
therewith) under such Act or otherwise, insofar as such loss, liability, claim,
damage, or expense arises out of or is based upon any untrue statement or
alleged untrue statement of any material fact furnished by the Pledgor contained
in any registration statement under which such securities were registered under
such Act or other securities laws, any preliminary prospectus or final
prospectus contained therein, or arise out of or are based upon any omission or
alleged omission by the Pledgor to state therein a material fact required to be
stated or necessary to make the statements therein not misleading, such
indemnification to remain operative regardless of any investigation made by or
on behalf of any Indemnified Party; provided, however, that the Pledgor shall
not be liable in any case to the extent that any such loss, liability, claim,
damage, or expense arises out of or is based upon an untrue statement or alleged
untrue statement or an omission or an alleged omission made in reliance upon and
in conformity with written information furnished to the Pledgor by an
Indemnified Party specifically for use in such registration statement or
preliminary or final prospectus.

      6.3. Application of Proceeds. The Agent shall apply the proceeds of the
Collateral, including the proceeds of any sales or other disposition of the
Collateral, or any part thereof, under Section 6, to payment of such part of the
Obligations and in such order as the Agent determines in its sole discretion,
unless a court of competent jurisdiction shall otherwise direct.


                                      -9-
<PAGE>

      6.4. Governance. All rights and remedies available to the Agent or the
Lenders with respect to the grant, foreclosure and enforcement of the security
interest and lien granted hereby and with respect to any action permitted
hereunder may be exercised solely by the Agent acting, where so required by the
Loan Agreement, with the concurrence of the Required Lenders.

      7. WAIVERS, AMENDMENTS AND REMEDIES.

      No delay or omission of the Agent to exercise any right or remedy granted
under this Pledge Agreement shall impair such right or remedy or be construed to
be a waiver of any Default or an acquiescence therein, and any single or partial
exercise of any such right or remedy shall not preclude other or further
exercise thereof or the exercise of any other right or remedy, and no waiver,
amendment or other variation of the terms, conditions or provisions of this
Pledge Agreement whatsoever shall be valid unless in writing signed by the Agent
with the concurrence, where so required by the Loan Agreement, of the Required
Lenders, and then only to the extent in such writing specifically set forth. All
rights and remedies contained in this Pledge Agreement or by law afforded shall
be cumulative and all shall be available to the Agent and the Lenders until the
Obligations have been paid in full.

      8. GENERAL PROVISIONS.

      8.1. Indemnity. The Pledgor hereby agrees to assume liability for, and
does hereby agree to indemnify and keep harmless the Agent and the Lenders, and
their respective successors, assigns, agents, employees, directors, officers,
attorneys, accountants and other representatives (each an "Indemnitee"), from
and against any and all liabilities, damages, penalties, suits, costs and
expenses of any kind and nature, imposed on, incurred by or asserted against any
of the Indemnitees, in any way relating to or arising out of any action taken or
failure to act by the Pledgor under or in respect of this Pledge Agreement,
provided that no such Person shall be entitled to indemnification for
liabilities, damages, penalties, suits, costs and expenses caused by its or
their own gross negligence or willful misconduct.

      8.2. Secured Party Performance of Pledgor Obligations. Without having any
obligation to do so, if a Default has occurred and is continuing the Agent may
perform or pay any obligation which the Pledgor has agreed to perform or pay in
this Pledge Agreement and the Pledgor shall reimburse the Agent for any amounts
paid by the Agent pursuant to this Section 8.2. The Pledgor's obligation to
reimburse the Agent pursuant to the preceding sentence shall constitute an
Obligation payable on demand.

      8.3. Authorization for Secured Party to Take Certain Action. The Pledgor
irrevocably authorizes the Agent at any time and from time to time in the sole
discretion of the Agent and appoints the Agent as its attorney in fact to act on
behalf of the Pledgor (i) to execute on behalf of the Pledgor as debtor and to
file financing statements necessary or desirable in the Agent's sole discretion
to perfect and to maintain the perfection and priority of the Agent's security
interest in the Collateral, (ii) to indorse and collect any cash proceeds of the
Collateral, (iii) to file a carbon, photographic or other reproduction of this
Pledge Agreement or any financing statement with respect to the Collateral as a
financing statement in such offices as the Agent in its sole discretion deems
necessary or desirable to perfect and to maintain the perfection and


                                      -10-
<PAGE>

priority of the Agent's and the Lenders' security interest in the Collateral,
and (iv) to apply the proceeds of any Collateral received by the Agent to the
Obligations as provided in Section 6.3 if a Default has occurred and is
continuing.

      8.4. Specific Performance of Certain Covenants. The Pledgor acknowledges
and agrees that a breach of any of the covenants contained in Sections 5.1 and
5.3 will cause irreparable injury to the Agent and the Lenders, that the Agent
and Lenders have no adequate remedy at law in respect of such breaches and
therefore agrees, without limiting the right of the Agent or the Lenders to seek
and obtain specific performance of other obligations of the Pledgor contained in
this Pledge Agreement, that the covenants of the Pledgor contained in the
Sections referred to in this Section 9.4 shall be specifically enforceable
against the Pledgor.

      8.5. Definition of Certain Terms. Terms defined in the New York Uniform
Commercial Code which are not otherwise defined in this Pledge Agreement are
used in this Pledge Agreement as defined in the New York Uniform Commercial Code
as in effect on the date hereof.

      8.6. Benefit of Agreement. The terms and provisions of this Pledge
Agreement shall be binding upon and inure to the benefit of the Pledgor, the
Agent and the Lenders and their respective successors and assigns, except that
the Pledgor shall not have the right to assign its rights under this Pledge
Agreement or any interest herein, without the prior written consent of the
Agent.

      8.7. Survival of Representations. All representations and warranties of
the Pledgor contained in this Pledge Agreement shall survive the execution and
delivery of this Pledge Agreement.

      8.8. Taxes and Expenses. Any taxes (including income taxes other than
taxes on the overall net income of the Lenders) payable or ruled payable by
Federal, Provincial or State authority or other Governmental Body in respect of
this Pledge Agreement shall be paid by the Pledgor, together with interest and
penalties, if any. The Pledgor shall reimburse the Agent for any and all
out-of-pocket expenses and internal charges (including reasonable attorneys'
fees and reasonable time charges of attorneys and paralegals who may be
employees of the Agent) paid or incurred by the Agent in connection with the
preparation, execution, delivery, administration, collection and enforcement of
this Pledge Agreement or in the collection, preservation or sale of the
Collateral.

      8.9. Headings. The title of and section headings in this Pledge Agreement
are for convenience of reference only, and shall not govern the interpretation
of any of the terms and provisions of this Pledge Agreement.

      8.10. Termination. This Pledge Agreement and the Lien arising hereunder
shall (i) become effective as of the date hereof upon the execution hereof and
(ii) continue in effect (notwithstanding the fact that from time to time there
may be no Obligations outstanding) until no Obligations or commitments of the
Pledgor or any of the Borrowers to the Agent or the Lenders which could give
rise to any Obligations shall be outstanding. Upon the termination of


                                      -11-
<PAGE>

this Pledge Agreement, the Agent will promptly deliver to the Pledgor (or to
such other Person as the Pledgor or a court of competent jurisdiction shall
direct), any Pledged Stock then still held by the Agent and not theretofore
disposed of in foreclosure or otherwise. Such delivery shall be without warranty
of, or recourse to, the Agent.

      8.11. Releases; Partial Releases. Any cash dividends received by the
Pledgor in accordance with the terms of Section 6.1(a) shall be deemed released
from the Lien of this Pledge Agreement and shall be held by the Pledgor (or any
transferee of Pledgor) free and clear of the Lien created by this Pledge
Agreement. Upon termination of this Pledge Agreement in accordance with the
provisions of Section 8.10, the Agent shall, at the Pledgor's request and
expense, execute such release as the Pledgor may reasonably request, in form and
upon terms acceptable to the Agent in all respects, and shall deliver all
certificates representing the Pledged Stock and other property held in respect
thereof hereunder which is in the Agent's possession, together with all stock
powers or other instruments of transfer reasonably required to effect delivery
to the Pledgor.

      8.12. Entire Agreement. This Pledge Agreement together with the Loan
Agreement and the other Loan Documents embodies the entire agreement and
understanding among the Pledgor, the Lenders and the Agent relating to the
Collateral and supersedes all prior agreements and understandings among the
Pledgor, the Lenders and the Agent relating to the Collateral.

      8.13. CHOICE OF LAW. THIS PLEDGE AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF
NEW YORK BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

      8.14. Waivers. Except to the extent expressly otherwise provided herein or
in any Loan Document, the Pledgor waives, to the extent permitted by applicable
law, (i) any right to require the Agent or any Lender to proceed against any
other Person, to exhaust their rights in any other collateral, or to pursue any
other right which the Agent or any Lender may have, (ii) with respect to the
Obligations, presentment and demand for payment, protest, notice of protest and
non-payment, and notice of the intention to accelerate, and (iii) all rights of
marshalling in respect of any and all of the Collateral.

      8.15. Agent Appointed Attorney-In-Fact. The Pledgor hereby irrevocably
appoints the Agent as Pledgor's attorney-in-fact, with full authority in the
place and stead of the Pledgor and in the name of the Pledgor or otherwise, from
time to time in the Agent's discretion reasonably exercised, to take any action
and to execute any instrument that the Agent deems reasonably necessary or
advisable to accomplish the purposes of this Pledge Agreement, including,
without limitation, to receive, endorse and collect all instruments made payable
to the Pledgor representing any dividend, interest payment or other distribution
in respect of the Collateral or any part thereof and to give full discharge for
the same, when and to the extent permitted by this Pledge Agreement.

      8.16. Severability. The provisions of this Pledge Agreement are severable
and if any clause or provision hereof shall be held invalid or unenforceable in
whole or in part, then such


                                      -12-
<PAGE>

invalidity or unenforceability shall attach only to such clause or provision, or
part thereof, and shall not in any manner affect such clause or provision in any
other jurisdiction or any other clause or provision in this Pledge Agreement or
any jurisdiction.

      9. NOTICES.

      9.1. Sending Notices. Any notice required or permitted to be given under
this Agreement may be, and shall be deemed, given and sent in accordance with
the provisions of the Guaranty.
