       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                 (Dollars in thousands, unless otherwise noted)

6.       JOINT VENTURES

The Company owns 50% of American Iron Reduction, L.L.C. ("AIR"), a joint venture
company producing direct reduced iron ("DRI"). AIR started operations in January
1998 and has rated capacity of approximately 1.2 million metric tons of DRI
annually. DRI is a substitute for high quality steel scrap used in steel making
facilities.

The Company is also party to a DRI purchase agreement with AIR with a term of
approximately 12 years, subject to cancellation or extension as provided for in
the agreement, pursuant to which the Company agrees, subject to the terms of the
agreement, to purchase a maximum of 600,000 metric tons of DRI annually, if
produced and tendered by AIR. The Company's cost of acquiring DRI from AIR
approximates AIR's total cash cost. The Company accounts for DRI purchased from
AIR and resold to others as components of net sales and cost of products sold
and accounts for DRI used in its own steelmaking operations as a component of
production cost. Income or losses from joint ventures, including AIR, are
reported in the statement of operations under the caption "Equity in income
(loss) of joint ventures". During the six months ended June 30, 1999, the
Company sold most of its purchases of DRI to a third party at negative gross
margins.

Because of problems with its third party material handling facility, the date
for the conversion of AIR's construction loan to term loan status was extended
until March 31, 1999. AIR and its lenders were unable to agree upon conditions
of conversion and effective March 31, 1999, AIR defaulted under the terms of the
loan agreement. Discussions are currently underway with AIR's lenders regarding
a restructuring of AIR's loan agreement. However, there can be no assurance that
negotiations with AIR's lenders will be successful or completed on terms that
will not have an adverse impact on the Company's future cost of DRI or on the
Company's cash flows. Under certain circumstances, the Company may be required
to make an additional equity contribution to this joint venture of up to $3.7
million.

7.       PAYABLES AND ACCRUED LIABILITIES

Payables and accrued liabilities consist of the following:

                                                 December 31,       June 30,

8.       CLAIM SETTLEMENTS

During the first six months of 1999, the Company realized $6.9 million of
pre-tax gains, classified as a reduction in cost of goods sold, from settlements
reached with the Company's suppliers of electrodes resulting from antitrust
claims investigations against the electrode suppliers and from a customer of the
Company in settlement of the Company's claim related to such customer's minimum
purchase requirements.

9.       NOTES PAYABLE

Notes payable of $7.4 million consists of short-term revolving credit facilities
in Chile, Peru, and the Philippines.

10.      COMMITMENTS AND CONTINGENCIES

LITIGATION AND OTHER CONTINGENCIES

In August, 1996, Samsung America, Inc. ("Samsung") filed an action in the
Supreme Court of the state of New York seeking monetary damages against GSI, the
Company, its Peruvian subsidiary, Acerco, and Acerco's partners in the Siderperu
joint venture, collectively, ("the Defendants"). Samsung seeks to recover
purported compensatory damages of $48.5 million and punitive damages of $10.0
million and alleges that the Defendants failed to honor a written contract which
entitled Samsung to obtain an equity interest in Siderperu and to provide
certain distribution and trading services on an exclusive basis. The Company
believes that it has substantial and meritorious defenses and will defend itself
accordingly.

The Company's subsidiary, Georgetown Steel Corporation, is the defendant in
three related suits filed in June 1998 and July 1998 by certain private
plaintiffs in the Court of Common Pleas for the County of Georgetown, South
Carolina. The plaintiffs allege trespass, nuisance, negligence and violation of
State and Federal law in connection with the escape of "mill dust" and gases
from Georgetown's steel mill into the atmosphere and onto the plaintiffs'
property in Georgetown, South Carolina. The plaintiffs seek certification as a
class action in each case. The plaintiffs in these actions seek unspecified
actual, compensatory and punitive damages. The Company believes the actions lack
merit and intends to defend itself vigorously.

There are various claims pending involving the Company arising out of the normal
course of business. In management's opinion, the ultimate liability resulting
therefrom will not materially effect the financial position or results of
operations of the Company.

ENVIRONMENTAL MATTERS

The Company's U.S. facilities are subject to a broad range of federal, state and
local environmental requirements, including those governing discharges to the
air and water, the handling and disposal of solid and hazardous wastes and the
remediation of contamination associated with releases of hazardous substances at
Company facilities and associated offsite disposal locations. Liabilities with
respect to hazardous substance releases arise principally under the federal
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")
and similar state laws, which impose strict, retroactive, joint and several
liability upon statutorily defined classes of "potentially responsible parties."
The Company's foreign facilities and joint ventures are subject to varying
degrees of environmental regulation in the jurisdictions in which those
facilities are located.

Based on the continuing review of environmental requirements, the Company
believes it is currently in compliance with environmental requirements.
Nevertheless, as is the case with steel producers in general, if a release of
hazardous substances occurs on or from the Company's properties or any
associated offsite disposal locations, or if contamination from prior activities
is discovered at such properties or locations, the Company may be held liable
and may be required to pay the cost of remedying the condition or satisfying
third party damage claims. The amount of any such liability could be material.
The Company devotes considerable resources to ensuring that its operations are
conducted in a manner that reduces such risks.

The Company has several environmental issues currently under discussion with
various federal and local agencies, some of which involve compliance and/or
remediation at certain properties. The Company records certain operating
expenses for environmental compliance, testing and other environmental related
costs as expenses when incurred. When it has been possible to determine
reasonable estimates of liabilities related to environmental issues, based upon
information from engineering and environmental specialists, the Company has made
provisions and accruals. At June 30, 1999, $2.6 million was accrued for
environmental related issues. The Company believes, based upon information
currently available to management, that it will not require expenditures to
maintain compliance with environmental requirements which would have a material
adverse effect on its financial condition, results of operations or competitive
position. As part of the purchase and sale agreement with a former owner, the
Company has been indemnified, through November 1999, for certain environmental
issues at certain of its facilities.

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998.

AMERICAN IRON REDUCTION LLC ("AIR"). The Company owns 50% of AIR which produces
direct reduced iron ("DRI") and commenced operations in January 1998. This
facility is capable of producing 1.2 million metric tons of DRI annually.
However, during late 1998 and continuing during the first six months of 1999,
production was scaled back as market conditions caused scrap and scrap
substitute demand and pricing to fall dramatically. The Company realized a net
equity loss from this joint venture of $4.8 million for the first half of 1999.
Additionally, the Company incurred a loss of $1.5 million on sales of DRI to
third parties during the first six months of 1999.

CLAIM SETTLEMENTS. During the first six months of 1999, the Company realized
$6.9 million of pre-tax gains, classified as a reduction in cost of goods sold,
from settlements reached with the Company's suppliers of electrodes resulting
from antitrust related claims against the electrode suppliers and from a
customer of the Company in settlement of the Company's claim related to such
customer's minimum purchase requirements.

NET SALES. Net sales decreased by $43.5 million to $397.9 million in the first
half of 1999 compared to the first half of 1998. The Company's total shipment
volume increased approximately 3,300 tons to 1,126,000 tons for the first half
of 1999. However, depressed pricing experienced by the domestic steel industry
due to high levels of low priced imported steel products resulted in an overall
decline in net sales. Wire rod sales of $192.9 million for the first six



                                       11

months of 1999 were below 1998 sales by approximately $26.5 million despite an
increase in shipments of approximately 31,600 tons as average wire rod selling
prices declined $55 per ton from the comparable six-month period of 1998.
Revenues from the Company's grinding media and mill liner shipments for the
first half of 1999 were down on a combined basis by approximately $8.7 million
from 1998 levels due primarily to lower selling prices.

The Company's wire products sales were up approximately $2.5 million to $44.8
million for the first six months of 1999 from an approximate 8,600 ton increase
in total shipments, partially offset by a decrease in average selling prices.

COST OF PRODUCTS SOLD AND GROSS MARGIN. Cost of products sold as a percent of
net sales remained constant at 87.8% for each of the six-month periods. Margins
continued to be adversely impacted by declines in average selling prices and
losses on sales of DRI to third parties. These negative factors were partially
mitigated by reductions in the Company's raw material costs and the claims
settlements recorded in the first half of 1999 as discussed above.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses for the first half have increased $2.5 million to $24.1
million. The increase results from costs associated with new system
installations, Year 2000 compliance programs and the recruitment and relocation
of certain management personnel.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization expense for the
first six months increased by $0.2 million to $16.0 million. This increase
results from capital additions and improvements.

NET INTEREST EXPENSE. Net interest expense of $20.3 million for the first half
of 1999 remained relatively constant with the $20.5 million for the same period
of 1998.

GAIN ON DISPOSITION OF PROPERTIES. In June 1998, the Company recognized a gain
of $6.4 million on the disposition of properties, primarily an idle facility in
Italy and certain assets in Peru.

OTHER INCOME (EXPENSE). Other income (expense), which is primarily equity in
income (loss) of joint ventures and fees from joint ventures, was net expense of
$6.0 million for the first half of 1999 compared to net income of $2.5 million
in 1998. The change results primarily from an equity loss from AIR of $4.8
million for the first half of 1999 versus an equity loss of $1.9 million in
1998. Additionally, the Company realized an equity loss from its joint venture
in Peru of $3.9 million for the first half of 1999 compared to equity earnings
of $0.9 million for the first half of 1998. The joint venture in Peru
experienced a significant decline in volume due to an economic recession in that
country and worldwide steel industry conditions.

INCOME TAX PROVISION/BENEFIT. The Company recorded an income tax provision of
$2.1 million on a pre-tax loss of $17.7 million for the first six months of 1999
resulting in an effective rate that is not meaningful. This compares to an
income tax provision of $1.9 million on pre-tax earnings of $4.5 million for the
first six months of 1998 at an effective rate of 42.6%. The rate is effected by
limitations on the Company's ability to utilize foreign tax credits, net
operating loss carry forwards, and the nondeductibility of amortization expense
associated with the Company's acquisition premium. Changes in the mix of U.S.
and foreign earnings also affect the rate of taxation.

NET INCOME (LOSS). As a result of the factors discussed above, the Company had a
net loss of $19.7 million for the first six months of 1999 compared to net
income of $2.6 million for the first six months of 1998.

THREE MONTHS ENDED JUNE 30, 1999 COMPARED TO THREE MONTHS ENDED JUNE 30, 1998.

NET SALES. Net Sales for the second quarter of 1999 were $193.3 million compared
to $224.7 million for the second quarter of 1998. As discussed above, this
decrease results from declines in average selling prices being experienced by
the domestic steel industry.

Wire rod sales for the second quarter of 1999 were down $14.4 million to $93.5
million compared to the same period of 1998 due primarily to a substantial
decrease in average selling prices.

Grinding media sales were $47.8 million for the second quarter of 1999 compared
to $52.4 million in 1998 reflecting a decrease in volume of approximately 5,000
tons and a decrease in average selling prices quarter to quarter. Revenues from
the Company's grinding media and mill liner business declined approximately $8.3
million quarter to quarter from the combination of a 1,600 ton reduction in
volume and a decrease in average selling prices.



                                       12
<PAGE>   13

COST OF PRODUCTS SOLD AND GROSS MARGIN. Second quarter cost of products sold as
a percent of net sales decreased from 90.4% in 1998 to 88.9% in 1999. Conversion
costs were higher than normal in the second quarter of 1998 due to unusually
high temperatures which caused power interruptions and shortages and resulted in
higher electricity cost and reduced production.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.3 million for the second quarter of 1999 to
$11.9 million as the Company incurred costs associated with new system
installations, and Year 2000 compliance programs, and the recruitment and
relocation of certain management personnel.

OTHER INCOME (EXPENSE). Other income (expense) was net expense of $4.9 million
for the second quarter of 1999 compared to net income of $1.0 million for the
same three-month period of 1998. The change results primarily from an equity
loss at AIR of $3.7 million in 1999 compared to a $.7 million equity loss in
1998 and an equity loss from the Peruvian joint venture of $2.5 million in 1999
compared to equity earnings of $.1 million in the second quarter of 1998.

INCOME TAX PROVISION/BENEFIT. The Company recorded an income tax provision of
$.9 million on a pre-tax loss of $13.7 million. This compares to an income tax
benefit of $104,000 on a pre-tax loss of $188,000 for the second quarter of
1998.

NET INCOME (LOSS). As a result of the factors discussed above, the Company has a
net loss of $14.7 million for the three months ended June 30, 1999 compared to a
net loss of $84,000 for the same period of 1998.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1999, the Company had cash and cash equivalents of $8.7 million, a
decrease of $1.9 million from December 31, 1998. Operating activities provided
$7.2 million of cash during the six months ended June 30, 1999, composed
primarily of a net loss of $19.7 million, including a non-cash equity loss on
joint ventures of $7.6 million, non-cash depreciation and amortization of $16.0
million, dividends from joint ventures of $1.1 million and changes in current
assets and liabilities for the period providing $1.1 million; the Company
invested $9.9 million in properties and an additional $3.8 million in joint
ventures and financing activities provided $5.1 million.

While management believes that funds available from the Company's cash flow from
operations and credit facilities will be sufficient, in the aggregate, to fund
planned working capital and capital expenditure requirements for 1999,
management continues to evaluate alternative sources of funds. There are
fluctuations in the Company's working capital needs over the course of a year,
generally influenced by various factors such as seasonality, inventory levels
and the timing of raw material purchases. Due to these factors, management
believes that it is important for the Company to maintain borrowing facilities
in excess of working capital requirements.

The Company is currently in compliance with its restrictive debt covenants.
However, should any of the factors described under "Risk Factors" adversely
affect future operating results, the Company could violate one or more of its
restrictive covenants within the next twelve months. The Company is evaluating
its alternatives in the event that it is unable to comply with its restrictive
covenants in the near term. The alternatives include, but are not limited to,
obtaining waivers for possible future violations, amending the covenants or
refinancing the Company's outstanding obligations. If it becomes necessary to
obtain waivers or amendments, the Company does not expect that these
alternatives would have a significant impact on future results of operations.
However, should it become necessary to refinance one or more of the Company's
facilities, the Company may incur increased interest costs.

Capital expenditures in the Company's business tend to vary from year to year,
as the impact of major programs is concentrated in certain periods followed by
periods of maintenance spending. Management believes that this pattern is
typical of the industry. Recent capital spending has been maintenance related
with some focus towards growth in production, improvement in product quality and
reduction in product cost.

The Company manages its liquidity needs on a consolidated basis with borrowings
that will be available under the Company's Revolving Credit Facility, and
various credit facilities available at its subsidiaries and joint ventures.
Management believes that cash flows from operations, after being adversely
impacted in late 1998 and 1999 by depressed market conditions as discussed
herein, will begin to improve due to the ongoing benefits of its business
strategy, previously announced price increases, including its cost reduction
programs and capital investment projects.



                                       13
<PAGE>   14

Borrowings under the Revolving Credit Facility bear interest at a floating rate.
Increases in prevailing rates could adversely affect the Company's cash flow. To
the extent that the interest rate on the Revolving Credit Facility increases or
the principal amount outstanding increases, there will be corresponding
increases in the Company's interest obligations. Under the Revolving Credit
Facility, the Company's availability is $120.0 million (subject to a borrowing
base limitation). As of June 30, 1999, the unused availability under the
Revolving Credit Facility was $42.1 million, and $6.2 million of letters of
credit were outstanding.

ENVIRONMENTAL AND TAX CONTINGENCIES AND INDEMNIFICATION

Note 10 to the Company's Unaudited Consolidated Financial Statements is
incorporated herein by reference.

YEAR 2000

The Company is pursuing an organized program to assure that the Company's
systems will be Year 2000 compliant. The Company's Year 2000 program was
designed around phases, which included management awareness, system inventory
and assessment, modification or replacement, testing, contingency planning,
business partner communication, audit, and employee awareness. A Year 2000 team
has been established at each location. Specific action plans and timelines have
been established at each of the locations and periodic meetings are held to
monitor progress.

The Company has completed the phases of management awareness, systems inventory
and assessment. Critical systems were identified and prioritized and decisions
made relative to the modification versus replacement of systems deemed to be
non-compliant. The cost of modifications to existing systems is being charged to
current operations. Where systems have been replaced with new applications, the
cost has been capitalized.

At the end of the second quarter, the Company has substantially completed its
Year 2000 modifications. The remaining system modifications and replacements are
in progress and will be completed during the third quarter of 1999.

Testing of individual systems was conducted as the systems were changed or
modified. Testing of the integrated systems indicates that the Company is
substantially ready for the Year 2000 in terms of its local manufacturing,
infrastructure, support, and facility systems except as noted above. This time
frame allows for the completion of further testing as required and the
presentation of an employee awareness training session to assure that all
employees, from the factory floor to the executive offices are familiar with the
Year 2000 situation and are prepared for any unforeseen possibilities.

The estimated costs for correction of the Year 2000 issues is approximately $3
million. More than one-half of this amount expended to-date.

The Company's Year 2000 program includes communications with its outside
business partners to prepare for Year 2000 readiness. The Company requested
information from its suppliers and other partners to determine their Year 2000
compliance. If a business partner indicates that it will not be ready for the
Year 2000, the Company will develop a contingency plan to address the issue.

At the present time, the Year 2000 team is developing contingency plans assuming
a variety of possible scenarios. These scenarios include the possibilities of
non-compliance difficulties from the standpoint of a customer, supplier, or
internal manufacturing support function. How these scenarios are used will
depend on the results of the testing programs. The Company's goal is to have a
completed contingency plan in place in the third quarter of 1999, based on
information received from its customers and suppliers relative to their
compliance with Year 2000 issues.

The estimates and conclusions herein contain forward-looking statements and are
based on management's best estimates of future events. Risks to completing the
program include the availability of resources, the Company's ability to execute
the Company's Year 2000 program, and the ability of suppliers to bring their
systems into Year 2000 compliance. All statements made herein regarding our Year
2000 efforts are "Year 2000 Readiness Disclosures" made pursuant to the Year
2000 Information and Readiness Disclosure Act, and to the extent applicable, are
entitled to the protections of such act.

RISK FACTORS

During 1998 and continuing into 1999, the Company's results have been negatively
impacted by distressed market conditions within the domestic steel industry.
Distressed economic conditions in other countries, particularly in Asia, have
resulted in record levels of low priced steel being imported into the U.S. and
causing dramatic declines in selling prices industry-wide.

The Company's grinding media business has been affected by a slow-down in the
mining industry resulting from declining commodity prices.

The Company's steel making operations are heavily dependent on the availability
and price of electricity. Future operations could be affected by these factors.

The Company has announced wire rod price increases and intends to aggressively
pursue reductions in its conversion costs, particularly at its Kansas City
mini-mill. The Company will also continue to carefully evaluate capital spending
and invest only when anticipated economic returns clearly exceed cost and when
necessary to ensure proper maintenance of equipment.







ITEM 3:  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

There have been no material changes in the Company's market risk during the six
months ended June 30, 1999. The market risk inherent in the Company's financial
instruments represents potential changes in interest rates. The Company manages
interest rate risks by maintaining certain ratios of fixed to variable rate
debt. The Company does not currently use derivative financial instruments.
