REPORT OF INDEPENDENT ACCOUNTANTS
ON LIMITED REVIEWS


1    We have carried out limited reviews of the Quarterly Information (ITR) of
     Gerdau S.A. and its subsidiaries for the quarters ended March 31, 2004 and
     2003. This information is the responsibility of the Company's management.

2    Our reviews were carried out in conformity with specific standards
     established by the Institute of Independent Auditors of Brazil (IBRACON),
     in conjunction with the Federal Accounting Council (CFC), and mainly
     comprised: (a) inquiries of and discussions with management responsible for
     the accounting, financial and operating areas of the Company with regard to
     the main criteria adopted for the preparation of the quarterly information
     and (b) a review of the significant information and of the subsequent
     events which have, or could have, significant effects on the Company's
     financial position and operations.

3    Based on our limited reviews, we are not aware of any material
     modifications that should be made to the quarterly information referred to
     above in order that such information be stated in conformity with the
     accounting practices adopted in Brazil applicable to the preparation of
     quarterly information, consistent with the Brazilian Securities Commission
     (CVM) regulations.

4    Our reviews were conducted in order to issue a report on the Quarterly
     Information (ITR) referred to in paragraph 1, taken as a whole. The
     statement of cash flows, presented to provide additional information on the
     Company and its subsidiaries, is not required as an integral part of the
     Quarterly Information (ITR). The statement of cash flows was submitted to
     the review procedures mentioned in paragraph 2, and, based on our review,
     we are not aware of any material modifications that should be made for it
     to be properly presented, in all material respects, in relation to the
     Quarterly Information (ITR) taken as a whole.

     the quarter ended December 31, 2003. We audited this information upon its

NOTE 1 - OPERATIONS

Gerdau S.A. is a company of the Gerdau Group dedicated mainly to the production
of common and special steel rods and to the selling of general steel products
(flat and rods), through plants located in Brazil, Uruguay, Chile, Canada,
Argentina and the United States of America.

The Gerdau Group has an installed capacity of 14.5 million tons of coarse steel
per year, basically producing steel in electrical furnaces, from scrap and pig
iron acquired, for the most part, in the region near each plant (mini-mill
concept). Gerdau also operates plants which are capable of producing steel from
iron ore (through blast furnaces and direct reduction) and has a unit used
exclusively to produce special steel. It is the largest scrap recycling company
in Latin America and it is among the largest recycling companies in the world.

The industrial sector is the Company's most important market, including
manufacturers of goods such as vehicles and household and commercial equipment,
which basically use profiled steel in various available specifications. The next
most important market is the civil construction sector, which demands a high
volume of rods and grids for concrete. There are also numerous customers for
nails, staples and wires, commonly used in the agribusiness sector.

b)   CUSTOMERS - are stated at realizable values, and trade accounts receivable
     from foreign customers are adjusted based on exchange rates effective at
     the date of the Quarterly Information. The provision for credit risks was
     calculated based on a credit risk analysis, which included the history of
     losses, the individual situation of customers and the economic group to
     which they belong, the collateral and guarantees and the legal advisors'
     opinion, and is considered sufficient to cover eventual losses on amounts
     receivable;

C)   INVENTORIES - are stated at the lower of market value and average
     production or purchase cost;

d)   INVESTMENTS IN SUBSIDIARIES - are accounted for using the equity method.
     The result of the equity adjustment is recorded in an operating results
     account;

e)   FIXED ASSETS - are recorded at cost, net of depreciation. Depreciation is
     calculated on the straight-line basis, at rates which take into
     consideration the estimated useful lives of assets. Interest on financing
     used to finance construction in progress is added to the cost of
     construction;

f)   DEFERRED CHARGES - amortization is calculated on the straight-line basis,
     at rates determined based on the actual production of the implemented
     projects in relation to their installed capacities;

g)   FINANCING - is stated at the contract value plus the contracted charges,
     including interest and monetary or foreign exchange variations. Swap
     contracts that are linked to the loan agreements are classified together
     with the related loans;

h)   INCOME TAX AND SOCIAL CONTRIBUTION - current and deferred income tax and
     social contribution are calculated in accordance with the legislation in
     force;

i)   OTHER CURRENT AND LONG-TERM ASSETS AND LIABILITIES - are recorded at their
     realizable amounts (assets) and at their known or estimated amounts plus
     accrued charges and indexation readjustments (liabilities), when
     applicable;

j)   TRANSLATION OF FOREIGN CURRENCY BALANCES - the criterion used for asset and
     liability balances in foreign currency is the translation to local currency
     (R$) at the foreign exchange rate in effect at the date of the closing of
     the Quarterly Information (March 31, 2004 - US$ 1.00 = R$ 2.9086 and
     December 31, 2003 - US$ 1.00 = R$ 2.8892).

b)   The more significant accounting practices used in preparing the
     consolidated quarterly information are as follows:

     I)   Gerdau S.A. and its subsidiaries adopt consistent practices to record
          their transactions and value their assets and liabilities. The
          financial statements of foreign companies were translated using the
          exchange rate in effect at the date of the Quarterly Information and
          were adjusted to be in conformity with accounting practices adopted in
          Brazil.
     II)  Balance sheet balances arising from transactions between consolidated
          companies have been eliminated.
     III) Holdings of minority shareholders in subsidiaries are shown
          separately.

c)   On February 16, 2004 the subsidiary Gerdau Ameristeel Corporation signed an
     agreement for the purchase of all assets of Potter Form & Tie Co.,
     headquartered in Belvidere, Illinois, in the United States. The purchase
     price was US$ 11 million, equivalent at that date to R$ 31,995.

     presented below is the pro-forma statement of income, showing the results

The tax benefits recognized on tax losses and social contribution losses, as
well as the provision for losses, both in the Company and consolidated, are
supported by projections of future taxable income at present value, based on
technical studies of feasibility, approved by management. These studies
considered the history of the Company's profitability and the perspective of
maintaining future profitability, permitting estimated realization of these tax
benefits in a period not over ten years.

The deferred taxes on temporary differences, mainly tax contingencies, were
recorded based on the probability of their realization, after the evaluation of
the Company's legal advisors.

a) GUARANTEES

The loans contracted under the FINAME/BNDES program are backed by the financed
assets of the subsidiary Gerdau Acominas S.A. The other loans are backed by
sureties from controlling shareholders, on which the subsidiary pays
remuneration of 1% p.a. on the guaranteed amount.

b) COVENANTS

In the place of the tangible collateral usually required, certain financial
covenants must be observed, as follows:

I) Consolidated Interest Coverage Ratio - measures the debt service payment
capacity in relation to the Earnings before Interest, Taxes, Depreciation and
Amortization (EBITDA);

II) Consolidated Leverage Ratio - measures the debt coverage capacity in
relation to the EBITDA.

All covenants mentioned above are calculated on a consolidated basis and have
been observed. The penalty for non-compliance is the accelerated maturity of the
contracts.

The market value of Eurobonds was obtained using the quotation of the securities
in the secondary market.

The market value of swap contracts of subsidiaries in Brazil was obtained based
on future income projections for each contract, calculated based on the present
value of the forward U.S. dollar + coupon rates (assets) and forward CDI/IGP-M
rates (liabilities) and discounted to current value at the date of the Quarterly
Information using the projected future CDI/IGP-M rate for each maturity. The
same methodology is applied for the calculation of the market values of the swap
contracts of the subsidiary Gerdau Ameristeel Corporation, using the LIBOR rate
as the discount rate.

04.01 - NOTES TO THE QUARTERLY INFORMATION
- --------------------------------------------------------------------------------


Swap contracts related to financing contracts are classified together with the
related financing, as a contra entry to the "Financial expenses" account, and
are stated at cost plus accrued charges up to the date of the Quarterly
Information. Contracts not linked to such financing have been recorded at their
market value under the heading "Other accounts payable", in long-term
liabilities.

The Company believes that the balances of the other financial instruments, which
are recognized in the books at net contracted values, are substantially similar
to those that would be obtained if they were negotiated in the market. However,
because the markets for these instruments are not active, differences could
exist if they were settled in advance.

c) RISK FACTORS THAT COULD AFFECT THE COMPANY'S AND ITS SUBSIDIARIES' BUSINESS

Price risk: this risk is related to the possibility of price variations of the
products that the subsidiaries sell or in the prices of raw materials and other
inputs used in the production process. Since the subsidiaries operate in a
commodity market, their sales revenue and cost of sales may be affected by the
changes in the international prices of their products or materials. In order to
minimize this risk, the subsidiaries constantly monitor the price variations in
the local and international markets.

Interest rate risk: this risk arises as a result of the possibility of losses
(or gains) due to fluctuations in interest rates relating to Company assets
(investments) and liabilities. In order to minimize possible impacts resulting
from interest rate fluctuations, the Company and its subsidiaries have adopted a
policy of diversification, alternating between fixed rates and variable rates
(such as LIBOR and CDI), and periodically renegotiate contracts to adjust them
to the market.

Exchange rate risk: this risk is related to the possibility of fluctuations in
foreign exchange rates affecting financial expenses (or income) and the
liability (or asset) balance of contracts denominated in a foreign currency. In
order to manage the effects of these fluctuations, the Company and its
subsidiaries use "hedge" instruments, usually swap contracts, as described in
item "a" above.

Credit risk: this risk arises from the possibility of the subsidiaries not
receiving amounts arising from sales or investments at financial institutions.
In order to minimize this risk, the subsidiaries adopt the procedure of
analyzing in detail the financial and equity position of their customers,
establishing a credit limit and constant monitoring of their balance. In
relation to financial investments, the Company and its subsidiaries invest
solely in institutions with low credit risk, as assessed by rating agencies. In
addition, each institution has a maximum limit for investment, determined by the
credit committee.

Taxes, contributions and other liabilities are paid by the Company on their due
dates, which is a basic requirement to remain eligible for the REFIS program.

As collateral for this installment payment program, the Company pledged the land
and buildings of the subsidiary Gerdau Acominas S.A., located in the
municipality of Charqueadas, in the state of Rio Grande do Sul, where the
Piratini plant is located, amounting to R$ 78,494.

The total income tax and social contribution credits acquired from third parties
and used to offset fines and interest on the consolidation of the REFIS debts on
December 6, 2000, totaled R$ 57,040, and they were acquired for R$ 4,351. The
Company's own tax credits were not used.

d) PAES

The proportionally consolidated (52%) subsidiary Dona Francisca Energetica S.A.
enrolled, on June 30, 2003, in the PAES, established by Law 10684/03 through the
Federal Revenue Secretariat, to settle Corporate Income Tax (IRPJ), Social
Contribution on Net Income (CSLL), Social Integration Program (PIS) and Social
Contribution on Revenues (COFINS) debts. The balances of these tax debts are
recorded in Taxes and contributions payable, in current liabilities, and in
Other accounts payable, in long-term liabilities. The balances of the
renegotiated taxes were divided into 180 installments, of which 170 are not yet
due, are restated based on the TJLP and, at March 31, 2004, are composed as
follows:

NOTE 14 - PROVISION FOR CONTINGENCIES

The Company and its subsidiaries are parties to labor, civil, and tax processes.
Based on the opinion of its legal advisors, management believes that the
provision for contingencies is sufficient to cover probable and reasonably
estimable losses from unfavorable court decisions, and the final decisions will
not have significant effects on the financial position at March 31, 2004.

The balances of contingencies, net of the related judicial deposits, are as
follows:

I) TAX CONTINGENCIES

a) CONTINGENT LIABILITIES PROVIDED

a.1) Of the total provision, R$ 50,456 (Company and consolidated) refers to the
contingency of compulsory loans to Eletrobras, the constitutionality of which is
being questioned by the Company. In March 1995, the Federal Supreme Court judged
the proceedings against the taxpayers. In relation to the Company's proceedings,
some are pending decision, but the outcomes are already foreseeable, taking into
consideration prior decisions. The Company established a provision related to
"compulsory loans", taking into consideration that, although the payment to
Eletrobras was made as a loan: (i) the reimbursement to the Company would
probably be in the form of shares of Eletrobras; (ii) the conversion will be
made based on the equity value of shares; and (iii) based on the current
available information, the shares of Eletrobras are valued at substantially less
than the equity value.

a.2) R$ 6,891 (Company) and R$ 6,898 (consolidated) related to the
unconstitutionality of the Social Investment Fund (FINSOCIAL). Although the
Supreme Court has confirmed the constitutionality of the tax at the rate of
0.5%, some proceedings are still pending judgment, most of them in the Superior
Courts.

a.3) R$ 1,099 (Company) and R$ 18,106 (consolidated) related to amounts for
Value Added Tax on Sales and Services (ICMS), the majority of which is related
to credit rights involving the Finance Secretariat and the State Courts of the
First Instance in the state of Minas Gerais.

a.4) R$ 8,978 (Company) and R$ 47,695 (consolidated) related to social
contribution on net income. The amounts refer to challenges of the
constitutionality of the contribution in 1989, 1990 and 1992. Some proceedings
are pending decision, most of them in the Superior Courts. Of the provision, R$
38,600, fully deposited in court, refers to the offset of social contribution
losses over the limit of 30% of taxable income by the subsidiary Gerdau Acominas
S.A. The matter is the object of a court injunction in progress in the Federal
Regional Court of the 1st Region.

                                      -28-

a.5) R$ 19,993 (Company) and R$ 116,939 (consolidated) related to Corporate
Income Tax (IRPJ). Of the total provided, R$ 96,946 was fully deposited in
court, related to a lawsuit of the subsidiary Gerdau Acominas S.A. for the right
to pay the IRPJ after the full offset of tax losses, without complying with the
limit of 30% of taxable income. a.6) R$ 12,962 (Company) and R$ 25,834
(consolidated) on contributions due to social security which correspond to suits
for annulment by the Company with judicial deposits of practically the whole
amount involved, in progress in the Federal Court of the First Instance in the
state of Rio de Janeiro.

In the consolidated statements, the remaining amount refers to lawsuits
questioning the position of the National Institute of Social Security (INSS) in
terms of charging INSS contributions on profit sharing payments made by the
subsidiary Gerdau Acominas S.A., as well as on payments for services rendered by
cooperatives. Also, part of this provision refers to several INSS assessments
due to services contracted from third parties, in which the Institute accrued
debts related to the last ten years and assessed Gerdau Acominas S.A. as jointly
responsible. The assessments were challenged administratively and, if sustained,
will be challenged later in annulment proceedings, since the Company understands
that the right to set up part of the credits had expired, and that, anyway, the
subsidiary is not responsible.

a.7) R$ 1,831 (Company) and R$ 2,029 (consolidated), related to contributions
for the Social Integration Program (PIS), and R$ 6,387 (Company) and R$ 6,941
(consolidated), to Social Contribution on Revenues (COFINS), in connection with
lawsuits questioning the constitutionality of Law 9718, which changed the
calculation basis of these contributions. These suits are in progress in the
Federal Regional Court of the 2nd Region and the Federal Supreme Court.

a.8) R$ 1,273 (consolidated) related to a lawsuit brought by the subsidiary
Gerdau Acominas S.A. regarding the Government Severance Indemnity Fund for
Employees (FGTS) surcharges, which arose from the changes introduced by
Complementary Law 110/01. Currently, the corresponding court injunction is
awaiting the judgment of the extraordinary appeal filed by the Company. The
provided amount is fully deposited in court.

a.9) R$ 9,307 (Company) and R$ 13,237 (consolidated), related to the Emergency
Capacity Charge (ECE), as well as R$ 5,283 (Company) and R$ 7,400 (consolidated)
related to the Extraordinary Tariff Recomposition (RTE) included in the electric
energy bills of the Company's plants. According to the Company, these charges
are of a tax nature and, as such, are incompatible with the National Tax System
provided in the Federal Constitution. For this reason, the constitutionality of
this charge is being challenged in court. The lawsuits are in progress in the
Federal Justice of the First Instance of the states of Pernambuco, Ceara, Minas
Gerais, Rio de Janeiro, Sao Paulo, Parana, and Rio Grande do Sul, as well as in
the Federal Regional Courts of the 1st and 2nd Regions. The Company has fully
deposited in court the amount of the disputed charges.

a.10) R$ 300 (Company) and R$ 1,068 (consolidated) related to other processes of
a tax nature, most of which is deposited in court.

a.11) Judicial deposits, representing restricted assets of the Company, are
related to amounts deposited and maintained in court until the resolution of the
related legal matters. The balances of these deposits, which at March 31, 2004
amounted to R$ 36,438 (Company), R$ 183,724 (consolidated), are classified as a
reduction of the provision for tax contingencies recorded in the books.

b) REMOTE OR POSSIBLE CONTINGENT LOSSES, INVOLVING GREAT UNCERTAINTIES IN
RELATION TO THEIR REALIZATION AND WHICH THEREFORE HAVE NOT BEEN PROVIDED FOR:

b.1) The Company is defendant in debt foreclosures filed by the state of Minas
Gerais to demand ICMS credits arising mainly from the sales of products to
commercial exporters. The restated amount of the lawsuits totals R$ 31,466. The
Company did not set up a provision for contingency in relation to these
processes, since it considers this tax undue, because products for export are
exempted from ICMS.

b.2) The Company and its subsidiary Gerdau Acominas S.A. are defendants in tax
foreclosures filed by the state of Minas Gerais, which demand ICMS credits on
the export of semi-finished manufactured products. The total amount demanded is
R$ 173,135. The companies did not set up a provision for contingency in relation
to these processes since they consider this tax undue, because the products do
not fit the definition of semi-finished manufactured products defined by the
federal complementary law and, therefore, are not subject to ICMS.

b.3) Also, R$ 54,763 are demanded due to the understanding of the Federal
Revenue Secretariat that the transactions carried out by the subsidiary Gerdau
Acominas S.A. under the drawback concession granted by DECEX were not in
conformity with the legislation. Gerdau Acominas filed a preliminary
administrative defense of the legality of the arrangement, which is pending
judgment. Since the tax credit has not been definitely set up, and considering
that the arrangement that originated the mentioned demand conforms with the
assumptions required for the drawback concession, and also that the concession
was granted after analysis by the legal administrative authority, Gerdau
Acominas S.A. considers an unfavorable outcome to be remote and, for this
reason, did not set up a provision for the contingency.

c) CONTINGENT TAX GAINS:

c.1) The Company believes that the realization of certain contingent gains is
probable. Among them is a court-order debt security issued in 1999 in favor of
the Company by the state of Rio de Janeiro in the amount of R$ 26,580, arising
from an ordinary lawsuit regarding non-compliance with the Loan Agreement for
Periodic Execution in Cash under the Special Industrial Development Program
(PRODI).

Due to the default by the state of Rio de Janeiro and the non-regulation of
Constitutional Amendment 30/00, which granted the government a ten-year
moratorium for the payment of securities issued to cover court-order debts not
related to food, the realization of this credit is not expected in 2004.

c.2) Gerdau S.A. and its subsidiaries have filed several ordinary proceedings
related to the correction of the PIS calculation basis under Complementary Law
07/70, due to the declarations of unconstitutionality of Decree Laws 2445/88 and
2449/88. The companies expect to recover the taxes unduly paid. The Company
believes that the amount under discussion totals R$ 173,090 (consolidated).

c.3) Also, due to prior favorable decisions by the Courts, the Company and its
subsidiary Gerdau Acominas S.A. expect to recover IPI premium credits. Gerdau
S.A. has filed administrative appeals, which are pending judgment. With regards
to the subsidiary Gerdau Acominas S.A., the proceedings were directed directly
to the courts and are pending decision. The Company estimates a credit in the
amount of R$ 394,002 (consolidated).

II) LABOR CONTINGENCIES

The Company is also defending labor proceedings, for which there is a provision
of R$ 16,257 (Company) and R$ 30,048 (consolidated) at March 31, 2004. None of
these lawsuits refers to individually significant amounts, and the lawsuits
mainly involve claims due to overtime, health hazards and risk premium, among
others.

The balances of deposits in court, which, at March 31, 2004, totaled R$ 8,285
(Company) and R$ 10,266 (consolidated), are classified as a reduction of the
provision for labor contingencies.

II) CIVIL CONTINGENCIES

a) CONTINGENT LIABILITIES INCLUDED IN THE PROVISION

The Company (consolidated) is also defending in court civil proceedings arising
from the normal course of its operations and of its subsidiaries' operations,
including lawsuits arising from workplace accidents, and, at March 31, 2004, has
a provision of R$ 99,778 (consolidated) for these proceedings.

The provision refers mainly to the issue involving the jointly controlled (52%)
subsidiary Dona Francisca Energetica S.A. According to the resolution of the
Brazilian Electricity Regulatory Agency (ANEEL), the operations of the
subsidiary are restricted to the South submarket. Since some of its transactions
were carried out in the remaining submarkets, Dona Francisca Energetica S.A. may
have to acquire the sold energy from third parties. The subsidiary challenges in
court the validity of the ANEEL resolution and has obtained a favorable
preliminary injunction.

At March 31, 2004, the balances of deposits in court totaled R$ 1,262
(consolidated) and are classified as a reduction of the provision for
contingencies.

b) REMOTE OR POSSIBLE CONTINGENT LOSSES, INVOLVING GREAT UNCERTAINTIES IN
RELATION TO THEIR REALIZATION, AND WHICH HAVE NOT BEEN PROVIDED FOR:

b.1) An antitrust process involving Gerdau S.A., related to the representation
of two civil construction syndicates in the state of Sao Paulo that alleged that
Gerdau S.A. and other long steel producers in Brazil divide customers among
them, violating the antitrust legislation. After investigations carried out by
the National Secretariat of Economic Law (SDE) and based on public hearings, the
SDE is of the opinion that a cartel exists. This conclusion was also supported
by an earlier opinion by the Secretariat for Economic Monitoring (SEAE). The
process is pending evaluation by the Administrative Council for Economic Defense
(CADE), which will decide the matter.

Gerdau S.A. denies having engaged in any type of anti-competitive behavior and
understands, based on information available, including the opinion of its legal
advisors, that the administrative process until now includes many
irregularities, some of which are impossible to resolve.

In addition, the SDE report was issued before Gerdau S.A. had the chance to
reply to the closing arguments, which indicates that there was a bias in the
judgment made by the SDE. The same applies to the SEAE report, which does not
analyze the economic issues and is based exclusively on the witnesses'
testimony.

The mentioned irregularities also include non-compliance with the related
constitutional provisions and will affect, in a way that cannot be overcome, the
decision in the administrative system, based on the conclusions presented by the
antitrust authorities until now. Gerdau S.A. has pointed out and tried to defeat
all these irregularities and will continue doing so in relation to the
allegations and the irregularities in the administrative process. Gerdau S.A.
believes in a favorable outcome to this process, if not in the administrative
system, possibly in the judicial system.

Because of the above factors, no provision was set up for this case. According
to Brazilian legislation, fines of up to 30% of gross revenue in the prior
fiscal years may be applied against the Company and, if the personal
responsibility of an executive is proven, such executive may be penalized by 10%
to 50% of the fine applied to the Company. There are no precedents in the
country for fines exceeding 4%. In a similar case involving flat steel
companies, the fine was 1%.

b.2) A civil lawsuit filed against Gerdau Acominas S.A. regarding the
termination of a contract for the supply of slag and indemnities for losses and
damages. At March 31, 2004, the lawsuit amounts to approximately R$ 36,366.

Gerdau Acominas S.A. contested all bases for the lawsuit and filed a
counterclaim for termination of the contract and indemnity for breach of
contract.

The judge declared the contract to be terminated, since such demand was common
to both parties. With regards to the remaining discussion, the judge understood
that both parties were at fault and judged unfounded the requests for indemnity.

This decision was maintained by the Court of Civil Appeals of the State of Minas
Gerais, and the agreement is based on expert evidence and interpretation of the
contract. The process is now with the High Court of Justice, for the judgment of
the appeal.

Gerdau Acominas S.A. believes that a loss from the case is remote, since it
understands that a change in the judgment is unlikely.

b.3) A civil lawsuit filed by Sul America Cia Nacional de Seguros against Gerdau
Acominas S.A. and Banco Westdeustsche Landesbank Girozentrale, New York Branch
(WestLB), for the payment of R$ 34,383 to settle an indemnity claim, which was
deposited in court. The insurance company pleads doubt in relation to whom
payment should be made and alleges that the Company is resisting in receiving
and settling it. The lawsuit was contested both by the bank (which claimed
having no right over the amount deposited, which resolves the doubt raised by
Sul America) and by the Company (which claimed inexistence of doubt and
justification to refuse the payment, since the amount owed by Sul America is
higher than stated). After pleading, Sul America claimed fault in the Bank's
representation, and the lawsuit is in its initial stage. Based on the opinion of
its legal advisors, the Company expects a loss to be remote and that the
sentence will declare the amount due within the amount stated in the pleading.

Also, Gerdau Acominas S.A. filed, prior to the above-mentioned lawsuit, a
lawsuit for the collection of the amount recognized by the insurance companies.
The lawsuits are pending. The Company expects a favorable outcome in this
lawsuit.

The civil lawsuits arise from the accident on March 23, 2002 with the blast
furnace regenerators of the Ouro Branco unit of the subsidiary Gerdau Acominas
S.A., which resulted in the stoppage of several activities, material damages to
the steel mill equipment and loss of profits. Equipment, as well as loss of
profits arising from the accident, was covered by an insurance policy. The
report on the event, as well as the loss claim, was filed with IRB - Brasil
Resseguros S.A., and an advance of R$ 62,000 was received in 2002.

In 2002, a preliminary and conservative estimate of indemnities related to the
coverage of loss of profits and material damages, in the total amount of
approximately R$ 110,000, was recorded, based on the amount of fixed costs
incurred during the period of partial stoppage of the steel mill activities and
the immediate expenses to be incurred to recover the equipment temporarily. This
estimate approximates the advance amount received plus the amount proposed by
the insurance company as a complement to settle the indemnity. Subsequently, new
amounts were added to the discussion, as stated in the Company's plea, although
not yet recorded.

Based on the opinion of its legal advisors, the Company considers that losses
from other contingencies that may affect the results of operations or the
Company's consolidated financial position are remote.

NOTE 15 - POST-EMPLOYMENT BENEFITS

a) PENSION PLAN - DEFINED BENEFIT

The Company and other Group subsidiaries in Brazil are the co-sponsors of
defined benefit pension plans that cover substantially all employees in Brazil
("Gerdau Plan" and "Acominas Plan").

The Gerdau Plan is managed by Gerdau - Sociedade de Previdencia Privada, a
closed supplementary pension entity to complement the social security benefits
of employees and retired employees of the Company, of the other units of Gerdau
Acominas S.A and other subsidiaries in Brazil. The assets of the Gerdau Plan
comprise investments in bank deposit certificates, federal public notes and
marketable securities.

The Acominas Plan is managed by Fundacao Acominas de Seguridade Social - Acos, a
closed supplementary pension entity to complement the social security benefits
of employees and retired employees of the Ouro Branco unit of Gerdau Acominas
S.A. The assets of the Acominas Plan mainly comprise investments in bank deposit
certificates, federal public notes, marketable securities and properties.

As a result of the operational integration on November 28, 2003, the assets and
liabilities of the Gerdau Plan, relating to the employees transferred to Gerdau
Acominas S.A., were allocated to the new sponsor, and the companies filed a
request with the Supplementary Social Security Secretariat to add Gerdau
Acominas S.A. as a sponsor of the Retirement and Supplementary Retirement Plans
managed by Gerdau - Sociedade de Previdencia Privada.

Also, the Canadian and American subsidiaries sponsor defined benefit plans
(Canadian Plan and American Plan) that cover substantially all their employees.

Wells Fargo, respectively, to complement the social security benefits of
employees of Gerdau Ameristeel Corporation and its subsidiaries. The assets of

b) PENSION PLAN - DEFINED CONTRIBUTION

The Company and its subsidiaries in Brazil are also the co-sponsors of a defined
contribution pension plan administered by Gerdau - Sociedade de Previdencia
Privada. Contributions are based on a percentage of the compensation of
employees.

The foreign subsidiary Gerdau AmeriSteel US Inc. has a defined contribution
plan, the contributions to which are 50% of the amount paid by the participants,
limited to 4% of the salary. The other companies do not have this type of
pension plan.

c) OTHER POST-EMPLOYMENT BENEFITS

The Company estimates that the balance payable, due to employees' retirement or
discharge, amounts to R$ 8,854 (consolidated) at March 31, 2004.

The American Plan includes, in addition to pension benefits, specific health
benefits for employees who retire after a certain age and with a certain number
of years of service. The American subsidiary has the right to change or
eliminate these benefits, and the contributions are based on amounts actuarially
calculated.

   year, 25.4% higher than in the same quarter of 2003, due to the increase in
   physical sales volume, better performance in the North American operations
   and the increase in prices of steel products in the foreign market. In
   relation to the fourth quarter of last year, net sales increased 18.7%.

o  In consolidated terms, the better operating margins of exports and of North
   American and Southern Cone operations were responsible for the maintenance of
   the Gross margin above 24%, even with the reduction of margins in Brazil,
   arising from the pressure on the input prices. During the first quarter of
   2004, consolidated gross margin was 24.4% against 25.0% in the same period of
   2003 and 24.7% in the last quarter of the year. Gross profit reached R$ 1.0
   billion in the months from January to March, 22.3% higher than the same prior
   year period.

o  Selling, general and administrative expenses reduced as a percentage of net
   sales for the quarter to 7.3%. This reduction, in relation to the first and
   fourth quarters of 2003, is a consequence, mainly, from the reduction of
   exports (less cost with port services) and the reduction of expenses in
   Gerdau Ameristeel. The operating expenses totaled R$ 305.5 million in the
   quarter.

o  Net financial expenses totaled R$ 153.6 million in the quarter. This amount
   includes monetary variation expenses of R$ 3.4 million and foreign exchange
   variation expenses of R$ 48.6 million. In the first quarter of 2003, net
   financial expenses totaled R$ 109.5 million, of which R$ 8.1 million were
   monetary variation expenses and R$ 16.7 million foreign exchange income.

o  Equity accounting was positive in the amount of R$ 17.0 million in the
   quarter. This amount reflects the variations of the different currencies in
   relation to the Real on Gerdau's foreign investments and also the tax
   incentives and amortization of goodwill.

o  Net income reached R$ 427.3 million in the first quarter of 2004, 48.7%
   higher than the first quarter of 2003. Net margin increased from 8.6% in the
   first three months of the year 2003 to 10.2% in the period from January to
   March 2004. In the comparison of the result for the quarter (R$ 427.3
   million) with the last quarter of last year (R$ 459.9 million) we note a
   reduction of 7.1%, but it should be considered that the 2003 profit includes
   R$ 135.7 million of tax credits. Excluding this amount, the effective growth
   would be 31.8% in the first quarter of 2004 in relation to the fourth quarter
   of 2003.

          the first and fourth quarters of 2003, respectively. When compared to

          throughout the year.

          quarter, presenting an increase of 15.9% over the pro forma for the

          at the same level. EBITDA margin stayed at 31.0% in the quarter.

     o    Interest on capital stock and dividends related to the first quarter
          and to be paid on May 18th, 2004, totaled R$ 103.2 million. This total

          R$ 20.63 per share.

products (flat and rods), through plants located in Brazil, Uruguay, Chile,
Canada, Argentina and the United States of America.

volume of rods and grids for concrete. There are also numerous customers for
nails, staples and wires, commonly used in the agribusiness sector.

The tax benefits recognized on tax losses and social contribution losses, as
well as the provision for losses, both in the Company and consolidated, are
supported by projections of future taxable income at present value, based on
technical studies of feasibility, approved by management. These studies
considered the history of the Company's profitability and the perspective of
maintaining future profitability, permitting estimated realization of these tax
benefits in a period not over ten years.

The deferred taxes on temporary differences, mainly tax contingencies, were
recorded based on the probability of their realization, after the evaluation of
the Company's legal advisors.


c) Estimated recovery of deferred income tax and social contribution assets:

A) GUARANTEES

The loans contracted under the FINAME/BNDES program are backed by the financed
assets of the Company. The other loans are backed by sureties from controlling
shareholders, on which the Company pays remuneration of 1% p.a. on the
guaranteed amount.

B) COVENANTS

In the place of the tangible collateral usually required, certain financial
covenants must be observed, as follows:

I) Consolidated Interest Coverage Ratio - measured the debt service payment
capacity in relation to the Earnings before Interest, Taxes, Depreciation and
Amortization (EBITDA);

II) Consolidated Leverage Ratio - measures the debt coverage capacity in
relation to the EBITDA.

All covenants mentioned above are calculated on a consolidated basis at the
Gerdau S.A. level and have been observed. The penalty for non-compliance is the
accelerated maturity of the contracts.

The market value of swap contracts was obtained based on future income
projections for each contract, calculated based on the present value of the
forward U.S. dollar + coupon rates (assets) and forward CDI rates (liabilities)
and discounted to current value at the date of the Quarterly Information using
the projected future CDI rate for each maturity. Swap contracts related to
financing contracts are classified together with the related financing, as a
contra entry to the "Financial expenses/income, net" account, and are stated at
cost plus accrued charges up to the date of the Quarterly Information.

The Company believes that the balances of other financial instruments, which are
recognized in the books at net contracted values, are substantially similar to
those that would be obtained if they were negotiated in the market. However,
because the markets for these instruments are not active, differences could
exist if they were settled in advance.

C) RISK FACTORS THAT COULD AFFECT THE COMPANY'S BUSINESS

Price risk: this risk is related to the possibility of price variations of the
products that the Company sells or in the prices of raw materials and other
inputs used in the production process. Since the Company operates in a commodity
market, its sales revenue and cost of sales may be affected by the changes in
the international prices of its products or materials. In order to minimize this
risk, the Company constantly monitors the price variations in the local and
international markets.

Interest rate risk: this risk arises as a result of the possibility of losses
(or gains) due to fluctuations in interest rates relating to Company assets
(investments) and liabilities. In order to minimize possible impacts resulting
from interest rate fluctuations, the Company has adopted a policy of
diversification, alternating between fixed rates and variable rates (such as
LIBOR and CDI), and periodically renegotiates contracts to adjust them to the
market.

Exchange rate risk: this risk is related to the possibility of fluctuations in
foreign exchange rates affecting financial expenses (or income) and the
liability (or asset) balance of contracts denominated in a foreign currency. In
order to manage the effects of these fluctuations, the Company uses "hedge"
instruments, usually swap contracts, as described in item "a" above.

Credit risk: this risk arises from the possibility of the Company not receiving
amounts arising from sales or credit instruments at financial institutions. In
order to minimize this risk, the Company adopts the procedure of analyzing in
detail the financial and equity position of its customers, establishing a credit
limit and constant monitoring of its balance. In relation to financial
investments, the Company invests solely in institutions with low credit risk, as
assessed by rating agencies. In addition, each institution has a maximum limit
for investment, determined by the Company's credit committee.

NOTE 12 -         PROVISION FOR CONTINGENCIES

The Company and its subsidiaries are parties to labor, civil, and tax processes.
Based on the opinion of its legal advisors, management believes that the
provision for contingencies is sufficient to cover probable and reasonably
estimable losses from unfavorable court decisions, and the final decisions will
not have significant effects on the financial position at March 31, 2004.

The balances of contingencies, net of the related judicial deposits, are as
follows:




                                                                    Company                       Consolidated

                                       90





I) Tax contingencies

a) Contingent liabilities provided

a.1) R$ 135,546 (Company and consolidated) related to Corporate Income Tax and
Social Contribution on Net Income being questioned in an injunction currently in
progress in the Federal Court of Appeals (TRF) of the 1st Region. The Company
claims the recognition of the right to pay the referred taxes after the offset
of tax losses without observing the limit of 30% of the taxable income. The
amounts discussed are being fully paid in court.

a.2) R$ 3,897 (Company) and 3,930 (consolidated), related to the Emergency
Capacity Charge (ECE), and R$ 2,066 (Company) and 2,117 (consolidated), related
to the Extraordinary Tariff Recomposition (RTE), included in the electric energy
bills of the Company's plants. According to the Company, these charges are of a
tax nature and, as such, are incompatible with the National Tax System provided
in the Federal Constitution. For this reason, the constitutionality of this
charge is being challenged in court. The lawsuits are in progress in the Federal
Justice of the First Instance of the states of Pernambuco, Ceara, Minas Gerais,
Rio de Janeiro, Sao Paulo, Parana, and Rio Grande do Sul, as well as in the
Federal Regional Courts of the 1st and 2nd Regions. The Company has fully
deposited in court the amount of the disputed charges.

a.3) R$ 17,008 (Company and consolidated) related to amounts for Value Added Tax
on Sales and Services (ICMS), the majority of which is related to credit rights
involving the Finance Secretariat and the State Courts of the First Instance in
the state of Minas Gerais.

a.4) R$ 1,273 (Company and consolidated) related to a lawsuit regarding the
Government Severance Indemnity Fund for Employees (FGTS) surcharges, which arose
from the changes introduced by the Complementary Law 110/01. Currently, the
corresponding court injunction is awaiting judgment of the extraordinary appeal
filed by the Company. The provided amount is fully deposited in court.

a.5) R$ 12,871 (Company and consolidated) refers to lawsuits questioning the
position of the National Institute of Social Security (INSS) in terms of
charging INSS contributions on profit sharing payments made by the Company, as
well as on payments for services rendered by cooperatives. Part of the provision
also refers to several INSS assessments due to services contracted from third
parties, in which the Institute accrued debts related to the last ten years and
assessed the Company as jointly responsible. The assessments were challenged
administratively and, if sustained, they will be challenged later in annulment
proceedings, since Gerdau Acominas understands that there the right to set up
part of the credits had expired, and that, anyway, the Company is not
responsible.

a.6) R$ 119 (consolidated) related to contributions for the Social Integration
Program (PIS) in connection with lawsuits questioning the constitutionality of
Law 9718, which changed the calculation basis of this contribution. These suits
are in progress in the Federal Regional Court of the 2nd Region.

a.7) R$ 45 (Company and consolidated) related to other tax claims, most of which
is deposited in courts.

a.8) Judicial deposits, representing restricted assets of the Company, are
related to amounts deposited and maintained in court until the resolution of the
related legal matters. The balances of these deposits, which at March 31, 2004
amounted to R$ 147,085 (Company) and R$ 147,178 (consolidated), are classified
as a reduction of the provision for tax contingencies recorded in the books.

B) REMOTE OR POSSIBLE CONTINGENT LOSSES, INVOLVING GREAT UNCERTAINTIES IN
RELATION TO THEIR REALIZATION, AND WHICH HAVE NOT BEEN PROVIDED FOR:

b.1) Gerdau Acominas S.A. is defendant in tax foreclosures filed by the state of
Minas Gerais, which demand ICMS credits on the export of semi-finished
manufactured products. The total amount demanded is R$ 149,993. The Company did
not set up a provision for contingency in relation to this process since it
considers this tax undue, because the products do not fit the definition of
semi-finished manufactured products defined by the federal complementary law
and, therefore, are not subject to ICMS.

b.2) Also, R$ 54,763 are demanded due to the understanding of the Federal
Revenue Secretariat that the transactions carried out by the Company under the
drawback concession granted by DECEX were not in conformity with the
legislation. The Company filed a preliminary administrative defense of the
legality of the arrangement, which is pending judgment. Since the tax credit has
not been definitely set up, and considering that the arrangement that originated
the mentioned demand conforms with the assumptions required for the drawback
concession, and also that the concession was granted after analysis by the legal
administrative authority, the Company considers an unfavorable outcome to be
remote and, for this reason, did not set up a provision for the contingency.

C) CONTINGENT TAX GAINS:

c.1) The Company is plaintiff in a proceeding related to the correction of the
PIS calculation basis under Complementary Law 07/70, due to the declarations of
unconstitutionality of Decree Laws 2445/88 and 2449/88. The Company expects to
recover the taxes unduly paid. The Company believes that the amount under
discussion totals R$ 62,628.

c.2) Due to prior favorable decisions by the Courts, the Company expects to
recover IPI premium credits. Gerdau Acominas S.A. has filed an injunction
challenging the return of credits, which is pending decision. The Company
estimates a credit in the amount of R$ 145,786.

II) LABOR CONTINGENCIES

The Company is also defending labor proceedings for which there is a provision
of R$ 13,791 (Company and consolidated) at March 31, 2004. None of these
lawsuits refer to individually significant amounts and the lawsuits mainly
involve claims due to overtime, health hazards and risk premium, among others.

The balances of deposits in court, which, at March 31, 2004, totaled R$ 1,981
(Company and consolidated), are classified as a reduction of the provision for
labor contingencies.

III) CIVIL CONTINGENCIES

A) CONTINGENT LIABILITIES INCLUDED IN THE PROVISION

The Company is also defending in court civil proceedings arising from the normal
course of its operations, including lawsuits arising from workplace accidents,
and, at March 31, 2004, has a provision of R$ 6,989 (Company and consolidated)
for these proceedings.

At March 31, 2004, the balances of deposits in court totaled R$ 1,262 (Company
and consolidated) and are classified as a reduction of the provision for
contingencies.

B) REMOTE OR POSSIBLE CONTINGENT LOSSES, INVOLVING GREAT UNCERTAINTIES IN
RELATION TO THEIR REALIZATION, AND WHICH HAVE NOT BEEN PROVIDED FOR:

b.1) A civil lawsuit filed against Gerdau Acominas S.A., regarding the
termination of a contract for the supply of slag and indemnities for losses and
damages. At March 31, 2004, the lawsuit amounts to approximately R$ 36,366.

Gerdau Acominas S.A. contested all bases for the lawsuit and filed a
counterclaim for termination of the contract and indemnity for breach of
contract.

The judge declared the contract to be terminated, since such demand was common
to both parties. With regards to the remaining discussion, the judge understood
that both parties were at fault and judged unfounded the requests for indemnity.
This decision was maintained by the Court of Civil Appeals of the state of Minas
Gerais and the process is now with the High Court of Justice, for the judgment
of the appeal.

The Company believes that a loss from the case is remote, since it understands
that a change in the judgment is unlikely.

b.2) A civil lawsuit filed by Sul America Cia. Nacional de Seguros against
Gerdau Acominas S.A. and Banco Westdeustsche Landesbank Girozentrale, New York
Branch (WestLB), for the payment of R$ 34,383, to settle an indemnity claim,
which was deposited in court. The insurance company pleads doubt in relation to
whom payment should be made and alleges that the Company is resisting in
receiving and settling it. The lawsuit was contested both by the bank (which
claimed having no right over the amount deposited, which resolves the doubt
raised by Sul America) and by the Company (which claimed inexistence of doubt
and justification to refuse the payment, since the amount owed by Sul America is
higher than stated). After pleading, Sul America claimed fault in the Bank's
representation, and the lawsuit is in its initial stage. Based on the opinion of
its legal advisors, the Company expects a loss to be remote and that the
sentence will declare the amount due within the amount stated in the pleading.

Also, the Company filed, prior to the above-mentioned lawsuit, a lawsuit for the
collection of the amount recognized by the insurance companies. The lawsuits are
pending. The Company expects favorable outcome to this lawsuit.

The civil lawsuits arise from the accident occurred on March 23, 2002 with the
blast furnace regenerators of the Company's Ouro Branco unit, which resulted in
the stoppage of several activities, material damages to the steel mill equipment
and loss of profits.

Equipment, as well as loss of profits arising from the accident, was covered by
an insurance policy. The report on the event, as well as the loss claim, was
filed with IRB - Brasil Resseguros S.A., and an advance of R$ 62,000 was
received in 2002.

In 2002, a preliminary and conservative estimate of indemnities related to the
coverage of loss of profits and material damages, in the total amount of
approximately R$ 110,000, was recorded, based on the amount of fixed costs
incurred during the period of partial stoppage of the steel mill activities and
immediate expenses to be incurred to recover the equipment temporarily. This
estimate approximates the advance amount received plus the amount proposed by
the insurance company as a complement to settle the indemnity. Subsequently, new
amounts were added to the discussion, as stated in the Company's plea, although
not yet recorded.

Based on the opinion of its legal advisors, the Company considers that losses
from other contingencies that may affect the results of operations or the
Company's consolidated financial position are remote.


NOTE 13 - POST-EMPLOYMENT BENEFITS

A)       PENSION PLAN - DEFINED BENEFIT

The Company and its subsidiary Armafer are the co-sponsors of defined benefit
plans that cover substantially all employees in Brazil ("Acominas Plan" and
"Gerdau Plan").

The Acominas Plan is managed by Fundacao Acominas de Seguridade Social - Acos, a
closed supplementary pension entity to complement the social security benefits
of employees and retired employees of the Ouro Branco unit. The assets of the
Acominas Plan mainly comprise investments in bank deposit certificates, federal
public notes, marketable securities and properties.

The Gerdau Plan is managed by Gerdau - Sociedade de Previdencia Privada, a
closed supplementary pension entity to complement the social security benefits
of employees and retired employees of the other units of Gerdau Acominas S.A.
The assets of the Gerdau Plan comprise investments in bank deposit certificates,
federal public notes and marketable securities.

As a result of the operational integration on November 28, 2003, the assets and
liabilities of the Gerdau Plan relating to the employees transferred to Gerdau
Acominas S.A., were allocated to the new sponsor, the companies filed a request
with the Supplementary Social Security Secretariat to add Gerdau Acominas S.A.
as a sponsor of the Retirement and Supplementary Retirement Plans managed by
Gerdau - Sociedade de Previdencia Privada.
