ITEM 1.        BUSINESS

                                     GENERAL

Lone Star Technologies, Inc. (Lone Star) is a management and holding company
that currently has one principal operating subsidiary, Lone Star Steel Company
(Steel). Steel serves three business segments: oilfield products, specialty
tubing products, and flat rolled steel and other tubular products and services.
Oilfield products are comprised of casing, tubing, and line pipe, that are
manufactured and marketed globally to the oil and gas drilling industry.
Specialty tubing products consist of Drawn Over Mandrel (DOM) tubing and
as-welded tubing that are manufactured and marketed globally to automotive,
fluid power, and other markets for various mechanical applications. Flat rolled
steel and other tubular products and services are manufactured and provided to
general industrial markets. Lone Star's consolidated revenues are not seasonal.
However, demand for Steel's oilfield products is subject to significant
fluctuations due to the volatility of oil and gas prices and domestic drilling
activity as well as other factors including competition from imports.

Lone Star was incorporated in Delaware in 1986 and became the holding company of
Steel, pursuant to Steel's merger with a wholly owned subsidiary of Lone Star.
In 1988, Lone Star acquired the stock of American Federal Bank (AFB), a
federally chartered savings bank. In November 1993, Lone Star sold the stock of
AFB. During August 1997, Lone Star received $12.4 million as a final payment on
the sale of AFB. The accompanying consolidated financial statements reflect this
payment as a gain from discontinued operations. During May 1991, a major
creditor group received 19.5% of the common stock of Steel, creating a minority
interest in Steel. In 1995, Lone Star repurchased 4.95% of Steel's common stock
from Steel's minority shareholders. In January 1997, all of the remaining
outstanding common stock, preferred stock, and warrants held by the other
minority shareholders of Steel were purchased by Lone Star, making Steel a
wholly owned subsidiary of Lone Star.

Additional segment information is included in Note B to the consolidated
financial statements.

OILFIELD PRODUCTS. Steel manufactures and markets oil country tubular goods
(OCTG) and line pipe.

OCTG offered by Steel includes the widest size and chemistry range of electric
resistance welded (ERW) high-quality prime casing and tubing for oil and gas
drilling and production in the United States. Casing, which historically
represents about 75% of all OCTG tonnage sold by Steel, is the structural
retainer for the walls of oil and gas wells. It also serves to prevent pollution
of nearby water reservoirs and to prevent contamination of a well's production.
Casing is generally not removed after it has been installed. Production tubing
is installed within the casing to convey oil and gas to the surface. Steel
offers the widest ranges of OCTG diameters (1.90" to 20") and grades produced in
the industry, including grades that have been successfully used for drilling at
depths of over 30,000 feet.

                                        3
<PAGE>

Demand for OCTG is affected by drilling activity which is driven by customers'
expectations of future oil and gas prices and political factors such as energy
and trade policies. Domestic drilling activity was down 13% in 1998 from the
prior year, according to the average number of rigs operating in the United
States as measured by Baker Hughes. However, the decline in drilling activity
accelerated in the second half of 1998 and by year-end only 621 rigs were
active, compared to 1,007 at the end of 1997. Steel's open orders for OCTG at
December 31, 1998, were down 78% from the prior year-end due to the decline in
drilling activity and high industry wide OCTG inventories. Approximately 7% of
shipments in 1998 were to destinations outside the United States. Sales and
earnings are affected by price, cost, availability of raw materials, oil and gas
drilling activity, general economic conditions, and an equitable trade
environment. Because of volatility of oil and gas prices and related drilling
activity as well as other factors such as competition from foreign imports,
demand for oilfield products can be subject to significant fluctuations.

LINE PIPE offered by Steel ranges in diameter from 2 3/8" to 16" and is used to
gather and transport oil and gas from the well site to storage or refining
facilities. Approximately 4% of Steel's line pipe shipments were exported in
1998.

SALES AND DISTRIBUTION. Steel's domestic OCTG sales distribution network
consists of 14 nonexclusive distributors that maintain and deliver product
inventory to major and independent oil and gas companies that explore for oil
and natural gas. Line pipe is also sold through nonexclusive distributors and
directly to end users. Internationally, OCTG is sold through distributors and
trading companies as well as directly to end users. The largest customer and the
second largest customer, both distributors of Steel's oilfield products in 1998,
accounted for 13% and 12% of total OCTG tons shipped, respectively. About 77% of
the oil and gas wells drilled in the United States in 1998 were located in
Texas, Oklahoma, Kansas, Louisiana, New Mexico, and the federal waters of the
Gulf of Mexico, all within 750 miles of Steel's mill in Lone Star, Texas. The
majority of Steel's oilfield products were sold for use in these states, as well
as the Gulf of Mexico which is less than 250 miles from Steel's mill.

ALLIANCE MILLS. In addition to production from its mill, Steel has marketing
agreements to sell other steel tubular products manufactured by six unrelated
companies. These arrangements are intended to expand Steel's product offerings
without a substantial investment in plant and equipment and enhance Steel's
marketing competitiveness. These transactions are performed on a commission
basis, through purchase and resale of the products, and under agreements to
process flat rolled steel provided by Steel into tubular products. These
arrangements accounted for over 15% of Steel's revenues from oilfield products
during 1998. Steel has commitments to buy tubular products from certain of its
alliance mills. Certain costs related to these commitments have been included as
part of the special charge related to supplier contracts discussed in Note C to
the consolidated financial statements.

RAW MATERIALS AND INVENTORIES. OCTG and line pipe are generally produced to fill
specific orders and, accordingly, Steel maintains the majority of its inventory
in the form of raw materials, work-in-process, or finished goods earmarked for
specific orders. Some work-in-process and finished inventories are maintained in
order to provide flexibility in responding to customer delivery demands.

Steel can use steel slabs, scrap steel, and steel coils in the manufacture of
its products. Steel primarily purchased steel slabs to meet production needs in
1998, and it was often necessary for Steel to commit to purchase slabs 90 to 150
days prior to production. Steel anticipates again using steel slabs for most of
its production needs in 1999 and has secured commitments from a major supplier
to be provided most of its steel slab requirements for 1999. Steel's principal
raw material for its internally produced steel slabs is steel scrap, which is
internally generated from Steel's operations or could be purchased in the spot
market. The price of scrap steel and steel slabs can be volatile and is
influenced by a number of competitive market conditions beyond the control of
Steel.

COMPETITION. OCTG and line pipe are sold in highly competitive markets. Steel
offers the widest range of sizes and chemistries in the United States and, based
on generally available market data, Steel believes that it is one of the largest
domestic suppliers of OCTG. Users of OCTG base their purchase decisions on four
factors: availability, price, quality, and service. Steel believes that it is
competitive in all of these areas.

Two primary markets exist for OCTG, and Steel serves both. Deep critical wells,
such as offshore wells, require high-

                                      4
<PAGE>

performance OCTG that can sustain enormous pressure as measured by burst 
strength, collapse strength, and yield strength. Both major and independent 
oil companies that conduct drilling programs of this nature emphasize quality 
and compliance with specific standards. Steel, with its full-body normalized 
ERW manufacturing process that meets American Petroleum Institute standards, 
often competes with seamless OCTG in this market. Operators drilling shallow 
wells generally purchase OCTG on the basis of price and availability because 
wells of this nature require fewer performance characteristics. Steel 
competes in this market, which is served primarily by producers of 
seam-annealed ERW and seamless OCTG, with its full range of Lone 
Star-Registration Trademark- products as well as with its Wildcat-TM- brand 
of OCTG.

Several domestic manufacturers produce limited lines of OCTG, and a number of 
foreign manufacturers produce OCTG for export to the United States. Imported 
OCTG accounted for approximately 24% of the apparent supply available to the 
domestic OCTG market during 1998, 16% during 1997, 14% during 1996 and 1995, 
as compared to 24% in 1994. The level of imported OCTG increased during 1998 
due to dislocations of inventories from certain foreign competitors whose 
traditional markets were encroached upon by other foreign manufacturers, 
particularly those subject to U.S. trade tariffs, as global drilling activity 
declined. A reduction of imported OCTG in the 1995 to 1997 period from levels 
experienced in the 1992 to 1994 period resulted from the imposition of 
protective tariffs on certain foreign countries in 1995. These trade tariffs, 
which were intended to promote an equitable trade environment, remained in 
effect during 1998.

Trade tariffs on OCTG from certain countries will be subject to sunset review 
beginning in May 1999. By law, the orders cannot be terminated prior to 
January 1, 2000. Trade tariffs on OCTG from more significant importers will 
be subject to review in August 2000. Under schedules proposed by the U.S. 
International Trade Commission, decisions in cases should be made 
approximately one year after initiation. Steel intends to join with other 
members of the U.S. industry to pursue its legal rights to continued relief 
from unfair trade practices.

SPECIALTY TUBING PRODUCTS.  Steel manufactures and markets specialty tubing.

SPECIALTY TUBING includes a wide array of high-quality, custom-made steel 
tubular products which require critical tolerances, precise dimensional 
control, and special metallurgical properties. Steel's specialty tubing 
products have the widest size range from 1/2" to 15" in outside diameter in 
North America and are made from a variety of combinations of chemical 
compositions, thermal treatments, mechanical properties, and surface 
finishes. Product uses include the manufacture of automotive, construction, 
and farm equipment and industrial applications such as hydraulic cylinders, 
stabilizer tubes, intrusion tubes, machine parts, bearing races, downhole 
pump barrels, heavy-lift crane boom chords, drill rods, and printing press 
rolls. Because of the wide range of industrial applications, sales 
traditionally follow general domestic economic conditions.

Steel produces most of its specialty tubing by the drawn over mandrel (DOM) 
process which uses a drawbench to pull tubing through a die and over a 
mandrel. Steel believes it has the second largest manufacturing capacity for 
DOM tubing in the world. The use of the DOM manufacturing process enables 
Steel to achieve higher critical tolerances and dimensional control than 
other processes. Steel's production facilities include seven drawbenches. 
It's 1,000,000 pound drawbench, the largest in the United States, and its 
800,000 pound drawbench enable Steel to access broader markets through the 
manufacture of larger diameter, thicker wall products. DOM specialty tubing 
order quantities are typically small (usually less than 50,000 pounds) and 
made to exact customer specifications.

Steel also produces as-welded specialty tubing which does not utilize the DOM 
process. A typical application for this product is trailer axles.

Demand for specialty tubing products, within the traditional markets, was 
down in 1998. Demand from certain Asian countries was lower due to Asian 
economic issues. Demand for hydraulic cylinders used in agricultural and 
construction related equipment declined as domestic farming activity 
decreased and building activity slowed in certain Asian economies.
Open orders at year-end 1998 were down 28% from the prior year-end.

SALES AND DISTRIBUTION. Domestically, specialty tubing is marketed and sold
through 19 nonexclusive steel service centers and directly to end users.
Specialty tubing products have detailed design specifications and in some cases
long lead times, making annual contracts an efficient mechanism for large
purchasers. The largest customer of Steel's specialty tubing in

                                        5
<PAGE>

1998 accounted for 13% of specialty tubing shipments. Internationally, the
majority of Steel's specialty tubing is currently sold directly to end users.
Exports accounted for approximately 19% and 26% of Steel's DOM specialty tubing
shipments in 1998 and 1997, respectively.

RAW MATERIALS AND INVENTORIES. Raw materials are readily available from multiple
sources. Production is generally scheduled to meet specific orders and,
accordingly, inventory is managed to minimize the amount of finished goods on
hand. Work-in-process inventories are maintained in order to provide flexibility
in responding to customer needs.

Steel can use steel slabs, scrap steel, and steel coils in the manufacture of
its products. Steel primarily purchased steel slabs to meet production needs in
1998, and it was often necessary for Steel to commit to purchase slabs 90 to 150
days prior to production. Steel anticipates again using steel slabs for most of
its production needs in 1999 and has secured commitments from a major supplier
to provide most of its steel slab requirements for 1999. Steel's principal raw
material for its internally produced steel slabs is steel scrap, which is
internally generated from Steel's operations or could be purchased in the spot
market. The price of scrap steel and steel slabs can be volatile and is
influenced by a number of competitive market conditions beyond the control of
Steel.

COMPETITION. The market for specialty tubing is competitive and is served by
several manufacturers. During 1996, Steel completed a capital expenditure
program to expand its specialty tubing capacity. Based on generally available
market data, Steel believes it has the second largest production capacity for
DOM specialty tubing products in the world.

Because these products are made to end-user specification and often require
just-in-time delivery, only small quantities are imported into the United
States. In contrast to the OCTG market, seamless and ERW specialty tubing
products differ in their applications. ERW is preferred for many mechanical
tubing applications because its consistent wall thickness requires less
machining in the finishing process. Seamless tubes are used primarily in heavy
gauge applications such as boiler and pressure tubing.

FLAT ROLLED STEEL AND OTHER TUBULAR PRODUCTS AND SERVICES. Steel manufactures 
and markets flat rolled steel and other miscellaneous tubular products that 
are secondary to its manufacture of oilfield and specialty tubing products. 
Steel's participation in the flat rolled steel commodity market to some 
extent involves its excess capacity for flat rolled steel as related to the 
manufacture of its oilfield and specialty tubing products and certain cost 
considerations associated with its total manufacturing operations.

FLAT ROLLED STEEL is primarily used by Steel in the manufacture of tubular
products. It is also sold to fabricators of large diameter transmission pipe,
storage tanks, rail cars, and a variety of other construction and industrial
products.

SALES AND DISTRIBUTION. Flat rolled steel is sold directly to end users and
through service centers, primarily in the southwestern region of the United
States. Due to an influx of inexpensive imported flat rolled steel during 1998,
markets for flat rolled steel experienced excess supply and lower pricing. As a
result, Steel's shipment volumes were down in 1998. However, preliminary
antidumping tariffs on certain foreign countries were imposed shortly after
year-end which should provide some relief to domestic markets. The largest
customer of Steel's flat rolled steel accounted for 89% of Steel's flat rolled
steel sales in 1998 as well as substantially all other sales of miscellaneous
tubular products other than oilfield and specialty tubing products. This
customer has steel processing facilities located adjacent to Steel's facilities
in East Texas, and those facilities purchase most of its flat rolled steel from
Steel. Sales to this customer represented approximately 10% of Steel's total
revenues for 1998.

RAW MATERIALS AND INVENTORIES. Steel produces flat rolled steel from its
internally produced slabs and slabs purchased from unrelated companies. Steel
can use steel slabs, scrap steel, and steel coils in the manufacture of its
products. Steel primarily purchased steel slabs to meet production needs in
1998, and it was often necessary for Steel to commit to purchase slabs 90 to 150
days prior to production. Steel anticipates again using steel slabs for most of
its production needs in 1999 and has secured commitments from a major supplier
to be provided most of its steel slab requirements for 1999. Steel's principal
raw material for its internally produced steel slabs is steel scrap, which is
internally generated from Steel's operations or could be purchased in the spot
market. The price of scrap steel and steel slabs can be volatile and is
influenced

                                        6
<PAGE>

by a number of competitive market conditions beyond the control of Steel.

COMPETITION. Flat rolled steel is sold in highly competitive markets generally
concentrated in the southwestern region of the United States. Sales and earnings
are affected by the cost of raw materials, use of flat rolled steel by Steel in
the manufacture of its tubular products, demand by outside customers, and
general economic conditions.

OTHER SERVICES. Transportation, storage, and other services are provided by
Steel's subsidiaries.

OTHER PRODUCTS. Steel markets its pipe as secondary products for use in
structural and piling applications in the construction industry.

                       RESEARCH, DEVELOPMENT, AND PATENTS

Steel conducts limited research and development activities at its metallurgical
laboratory on its facilities in East Texas. Its patents do not significantly
affect financial results.

                                    EMPLOYEES

At December 31, 1998, Lone Star and Steel had a total of 938 active employees,
of whom 480 were members of two unions represented by three bargaining units.
The majority of union workers are represented by the United Steelworkers of
America under a contract signed in May 1996, which expires on May 31, 2001, with
a provision to reopen the contract for wages but not other benefits or work
conditions after May 31, 1999. The other two agreements expire in 2000.
Management considers its relationship with its employees to be good.

                               FOREIGN OPERATIONS

Steel conducts no manufacturing operations outside the United States. Export
sales to destinations outside the United States were approximately $33.8
million, $58.1 million, and $50.0 million for the years 1998, 1997, and 1996,
respectively.

                                  ENVIRONMENTAL

Steel's operating activities are governed by numerous environmental laws, which
are regulated by state and federal agencies. The three major areas of regulation
are air quality, water quality, and solid and hazardous waste management.

RELATIONSHIP OF FEDERAL AND STATE REGULATION. The United States Environmental
Protection Agency (EPA) is responsible for implementing and enforcing federal
environmental laws. In Texas, the environmental regulatory agency is the Texas
Natural Resource Conservation Commission (TNRCC). Most federal environmental
statutes expressly provide for state assumption of responsibility when the state
can demonstrate that its program is as stringent as the federal program;
however, the EPA retains authority to enforce the program if the state fails to
do so. Texas is authorized to implement the federal hazardous waste program
under the Resource Conservation and Recovery Act (RCRA), the federal air quality
program under the Clean Air Act, and the federal water quality program under the
Clean Water Act. In addition, Texas has state environmental programs that
supplement and operate independently of the federal environmental programs.

AIR quality is governed by the federal Clean Air Act and the Texas Clean Air
Act. The Texas State Implementation Plan implements, maintains, and enforces the
federal air quality programs. The TNRCC rules implementing Title V of the
federal Clean Air Act require subject sources to apply for a general operating
permit. As required, Steel has submitted an abbreviated application for a
general operating permit. The TNRCC set July 22, 1999, as the deadline for
subject sources within the steel industry to submit full Title V applications;
this deadline applies to Steel and Steel intends to timely file the application.
Once the TNRCC issues Steel a Title V general operating permit, Steel will have
additional recordkeeping obligations.

Emission sources at Steel's facilities are currently regulated by a combination
of individual state permit limitations and statewide standards. Sources which
existed before the implementation of the state permitting requirements are
registered with the TNRCC as "grandfathered sources" and are not required to
obtain a state permit. If, however, a grandfathered source is modified in a
manner that increases the amount or changes the character of air contaminants
emitted into the atmosphere, it becomes subject to the state permitting
requirements. Steel is presently in substantial compliance with the conditions
of its state permits and applicable standards.

WATER quality is governed by the federal Clean Water Act and the state Water
Code. On September 14, 1998, EPA authorized the State of Texas to implement the
National Pollutant Discharge Elimination System (NPDES) through its state
program, the Texas Pollutant Discharge Elimination System (TPDES). Before
delegation, Steel was required to have two separate permits to discharge
wastewater from each of its outfalls: an NPDES permit issued by the EPA and a
wastewater discharge permit issued by the TNRCC. After delegation, Steel
continues to be required to have both permits until they are consolidated in a
permit renewal or permit amendment process into a single TPDES permit. Steel is
also required to have an NPDES permit to discharge storm water that is not
commingled with wastewater. Steel's storm water discharges are permitted through
the EPA's NPDES General Permit for Storm Water Discharges Associated With
Industrial Activities. The EPA will continue to administer this permit until it
expires on September 29, 2000, before which time, Steel will need to renew the
permit with the TNRCC.

Steel's NPDES permit was renewed on August 28, 1998, for a five-year term. In
Steel's renewal NPDES permit, EPA modified the lead limitations at Steel's major
process discharge to be consistent with the Texas Surface Water Quality
Standards for dissolved lead, which favorably addressed Steel's challenge to its
former NPDES permit. In addition, EPA removed from Steel's renewal NPDES permit
the whole effluent toxicity (WET) limits at Steel's major process discharge that
it had initially proposed to include in the permit. EPA took this latter action
pursuant to the Settlement Agreement that EPA and Steel entered on March 4,
1998, in partial settlement of Steel's Petition for Review of the WET test
method rule that EPA had adopted.

Steel's state wastewater discharge permit was amended effective September 14,
1998, to revise the lead limitations at its major process discharge to be
consistent with the Texas Surface Water Quality Standards for dissolved lead. On
January 8, 1999, the TNRCC issued Steel another amended permit that further
modified these lead limitations to be the same as those in Steel's NPDES permit.
Steel recently submitted an application to the TNRCC to renew and further amend
its state wastewater discharge permit, which will expire August 1, 1999. The
TNRCC will issue Steel a TPDES permit that will consolidate Steel's state and
federal permits.

SOLID AND HAZARDOUS WASTE management is governed by the Texas Solid Waste
Disposal Act and RCRA. The TNRCC has primary responsibility for implementing and
enforcing the federal law through the state program.

Solid waste, some of which is now classified as hazardous, has been generated by
Steel since it began operation. As with similar mills in the industry, Steel's
EAF generates dust containing lead, chromium, and cadmium. Until 1988, Steel
disposed of the EAF dust and other wastes in onsite management units. Hazardous
wastes, and most nonhazardous wastes, are now shipped off site to commercial
facilities for disposal or reclamation. EAF dust has been recycled for metals
recovery since 1991.

In the past, Steel operated solid waste management units for the storage and
disposal of nonhazardous and hazardous wastes. These sites include: (1) two
closed RCRA landfills; (2) two former RCRA units that were clean-closed or
closed as nonhazardous waste units and no longer require monitoring; and (3) one
unit that predates RCRA which was closed as a nonhazardous landfill, with
certification of closure submitted to the TNRCC in December 1998. The two RCRA
units require a post-closure care permit; the application is pending with the
TNRCC. The permit will specify the amount of financial assurance required for
post-closure care and what, if any, corrective action is required to address
Steel's remaining non-RCRA solid waste management units. Steel estimates the
actual cost of RCRA post-closure care to be approximately $310,000.

ITEM 2.        PROPERTIES

Steel conducts its operations at facilities on a 2,000-acre site in East Texas.
The original facilities, constructed in the 1940's and 1950's have been expanded
and modernized, and include two electric-arc furnaces (EAF) equipped with
oxy-fuel burners with a combined capacity of approximately 575,000 ingot tons
per year; two rolling mills, a "two-high" mill that rolls the EAF ingots into
slabs and a "four-high" single stand reversing Steckel mill that produces flat
rolled coils; coil slitting and handling equipment; two pipe welding mills;
seven draw benches, including the largest specialty tubing drawbench in the
United States; heat treating facilities; numerous types of ultrasonic and
electromagnetic testing and inspection equipment; finishing facilities at which
tubular goods are threaded and couplings are applied; and various support
facilities including a shortline railroad and other transportation and storage
facilities. Steel's and Lone Star's headquarters are located in leased
facilities in Dallas, Texas.

Steel's annual rated capacity approximates 480,000 slab tons, 1,400,000 flat
rolled tons, and 1,000,000 welded pipe tons. Steel has access through marketing
arrangements and agreements with alliance mills which provide additional
oilfield pipe capacity of approximately 250,000 tons. In 1998, the specialty
tubing facilities operated near 80% of capacity. The rolling mills and pipe
mills generally operated at approximately 50% of capacity, while the EAF's
operated at about 30% of capacity.

In addition to the manufacturing facilities, Steel owns 8,250 acres in Texas
which were purchased primarily for iron ore or coal reserves, and Steel owns
mineral interests in an additional 12,000 acres in Oklahoma and 60,000 acres in
Texas. No minerals have been recovered from these properties for many years
because their use is no longer required in Steel's operations. Steel owns
nominal oil and gas interests in an additional 9,400 acres in Texas.

ITEM 3.        LEGAL PROCEEDINGS

Management does not believe, based upon analysis of known facts and
circumstances and reports from legal counsel, that any pending legal proceeding
will have a material adverse effect on the financial condition of Lone Star and
its subsidiaries taken as a whole.

ITEM 4.        SUBMISSION OF MATTERS TO A VOTE OF SHAREHOLDERS

ITEM 7.        MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
               OPERATIONS AND FINANCIAL CONDITION

                                    OVERVIEW

Lone Star's revenues are derived from Steel's three business segments: oilfield
products, specialty tubing products, and flat rolled steel and other tubular
products and services.

PRODUCTS AND MARKETS. The oilfield products business includes the manufacture,
marketing and sales of OCTG, the casing and tubing used in oil and gas well
drilling and production, and line pipe that is used to gather and transport oil
and gas from the well site to storage or refining facilities. Steel is one of
the largest domestic producers and suppliers of OCTG, based on data compiled by
the American Iron & Steel Institute. Historically, OCTG has represented
approximately three-fourths of Steel's oilfield products volume as measured in
tonnage, and exports have ranged from approximately 7% to 9% of this segment's
shipments during the last three years.

Demand for oilfield products is generally affected by customers' expectations of
future oil and gas prices and political factors such as energy and trade
policies. A key indicator of domestic demand is the average number of drilling
rigs operating in the United States. According to Baker Hughes, the average
United States rig counts in 1998, 1997, and 1996 were 827, 943, and 779,
respectively. However, the decline in drilling activity accelerated in the
second half of 1998 and by year-end only 621 rigs were active compared to 1,007
at the end of 1997. Steel's open orders for OCTG at December 31, 1998 were down
78% from the prior year due to the decline in drilling activity and high
industry-wide OCTG inventories. Demand is also affected by the amount of
oilfield products imported into this country as well as available industry
inventories. Imported OCTG accounted for approximately 24% of the apparent
supply available to the domestic OCTG market during 1998, 16% during 1997, 14%
during 1996 and 1995, as compared to 24% in 1994. The level of imported OCTG
increased during 1998 due to dislocations of inventories from certain foreign
competitors whose traditional markets were encroached upon by other foreign
manufacturers, particularly those subject to U.S. trade tariffs, as global
drilling activity declined. A reduction of imported OCTG in the 1995 to 1997
period from levels experienced in the 1992 to 1994 period resulted from the
imposition of protective tariffs on certain foreign countries in 1995. These
trade tariffs, which were intended to promote an equitable trade environment,
remained in effect during 1998.

The effect of available inventory was significant last year as new mill
production of OCTG was largely displaced during the second half of the year by
consumption of excess industry wide inventories. The volatility of oil and gas
prices creates uncertainty with respect to the timing and extent of activity in
the energy sector. This affects customer confidence in the longer term outlook
for energy prices and directly affects drilling activity. Consequently, domestic
markets deteriorated in 1998 as oil and gas prices declined to levels that did
not justify additional exploration and production spending. Substantial
uncertainty exists regarding the future levels of oil and gas prices and related
drilling activity. Therefore, no assurance can be given regarding the extent of
future demand for Steel's OCTG products.

Steel's specialty tubing products segment includes two product groups: Drawn
Over Mandrel (DOM) tubing and as-welded tubing. Specialty tubing consists of a
wide array of high-quality, custom-made steel tubular products requiring
critical tolerances, precise dimensional control, and special metallurgical
properties. These products are used in the further manufacture of automotive,
construction, and other industrial equipment such as hydraulic cylinders,
stabilizer tubes and intrusion tubes, and machine parts.

Specialty tubing is used in a wide range of industrial applications and,
therefore, demand is sensitive to general economic conditions. Demand decreased
during 1998 and open orders were down 28% at year-end as compared to year-end
1997. International shipments were lower in 1998 due to lower economic activity
in certain Asian countries. Also, orders for specialty tubing used as hydraulic
cylinders were lower due to reduced demand for construction equipment in certain
Asian countries and decreased domestic agricultural equipment demand.
International shipments of DOM specialty tubing were 19%, 26%, and 19% of
shipments in 1998, 1997, and 1996, respectively.

Steel's participation in the flat rolled steel commodity market is generally
concentrated in the southwestern region of the United States and is affected by
factors such as price, capacity utilization, and raw material costs. Flat rolled
steel produced by Steel is primarily used by Steel in the manufacture of tubular
products, but is also sold to customers for the manufacture

                                       11
<PAGE>

of a variety of commercial and industrial products. Flat rolled steel is sold 
in highly competitive markets, with price, quality, and availability 
primarily determining customer purchase decisions. Due to an influx of 
inexpensive imported flat rolled steel during 1998, markets for flat rolled 
steel experienced excess supply and lower pricing. As a result, Steel's 
shipment volumes were down in 1998. However, preliminary antidumping tariffs 
on certain foreign countries were imposed shortly after year-end which should 
provide some relief to domestic markets.

MANUFACTURING. The manufacture of Steel's products is capital intensive.
Utilization rates declined significantly during 1998 at Steel's manufacturing
facilities. Operations of certain facilities were curtailed for significant
periods during the second half of 1998. The level of production volume through
Steel's various facilities has a significant effect on the cost of
manufacturing. Key variable costs include costs of raw materials, including
scrap steel, steel slabs, coils, electricity, and natural gas. Steel has entered
into certain marketing alliances and manufacturing arrangements with unrelated
companies involving the marketing of their products and processing of flat

1998 COMPARED WITH 1997

NET REVENUES of $432.4 million were 33.9% lower than 1997. Net revenues from
oilfield products declined 43.7% to $255.6 million in 1998. Shipment volumes and
prices were down from 1997 levels 41.1% and 4.4%, respectively. Demand for
Steel's OCTG decreased as drilling activities declined precipitously in the
second half of 1998. The average rig count was down 116 to 827 in 1998 with only
621 rigs operating at year-end, compared to 1,007 at the end of 1997. Demand was
also detrimentally impacted as new mill production was replaced by the
consumption of excess industry wide OCTG inventories. Also, demand declined due
to increased competition from imported OCTG which grew to 24% of the apparent
supply available to the domestic market from 16% in 1997.

Specialty tubing products revenues decreased by 4.5% to $123.2 million from
lower shipment volumes with slightly higher prices. Shipment volumes were down
6.6% due to reduced sales for hydraulic cylinder applications in agricultural
and construction related equipment and reduced international sales to certain
Asian countries.

                                       12
<PAGE>

Flat rolled steel and other tubular products revenues were down 24.7% to $53.6
million. Shipments were 25.4% lower due to a dramatic increase in inexpensive
imported foreign coils during 1998 that resulted in an excess supply of flat
rolled steel in domestic markets.

GROSS EARNINGS decreased from $64.2 million in 1997 to $4.4 million in 1998 due
to reduced shipment volumes in all products coupled with lower prices for
oilfield products and slightly higher prices for specialty tubing products.
Also, significantly decreased production volumes negatively impacted gross
margins as fixed and semi-fixed costs were absorbed by fewer units of
production.

SPECIAL CHARGES. In response to late 1998 and expected 1999 market conditions,
Steel has restructured and downsized its operations. The lower operating rates
resulted in the need to reduce employment levels and initiate other actions. As
a result of these actions, special charges of $14.5 million have been recognized
in the 1998 consolidated statement of operations, which include the following
items in millions:

<TABLE>

                Total special charges                                                        $14.5
</TABLE>

Certain facilities are expected to permanently reduce or eliminate their
operations, relying instead on alternative production or procurement methods.
This includes a reduction in the production level of the electric-arc furnace
steelmaking facilities, with heavier reliance to be placed on purchased steel in
coil and slab form. Additionally, some finishing processes and infrastructure
utility services have or are expected to be permanently abandoned and be
completely replaced through outside procurement. These actions triggered an
assessment of the recoverability of the asset carrying costs and the resulting
recognition of an impairment loss. The determination of the impairment loss was
based on an evaluation of future cash flows from operation of the steelmaking
facilities and estimated salvage values of the steelmaking facilities and those
facilities to be abandoned. The net book value of these assets, which included
property, plant and equipment supplies inventory, totaled $12.6 million, of
which $8.1 million is included in the special charges.

Certain existing supplier contracts are also being renegotiated or cancelled to
accommodate the lower operating levels. Estimated costs of $4.4 million
associated with renegotiating or cancelling these obligations that will provide
no future benefit have been included in the special charges and accrued at
December 31, 1998.

Steel has terminated employees or identified certain positions for elimination
as of December 31, 1998. Payments made to terminated employees are based on
Steel's standard severance package. Total employee severance costs included in
special charges totaled $2.0 million, of which $1.1 million had been paid by
December 31, 1998.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES increased 2.0% to $20.0 million
due primarily to continued higher spending related to year 2000 readiness
initiatives partially offset by lower selling expenses.

INTEREST INCOME decreased from $3.0 million in 1997 to $2.0 million in 1998 due
to lower average interest rates on invested cash, short-term investments and
marketable securities.

INTEREST EXPENSE decreased from $6.6 million in 1997 to $4.0 million in 1998 due
to the conversion of Lone Star's $50.0 million principal amount 8% convertible
subordinated debentures into common stock in August of 1997. Also, Steel's
revolving credit facility during 1998 had lower average interest rates which
were offset by higher average borrowings than in 1997.

OTHER EXPENSE. During 1998, other expense of $0.2 million was primarily related
to write-off of prepaid bank fees on the restructuring of Steel's revolving
credit facility partially offset by gains from nonrecurring miscellaneous items.
In 1997 other income of $0.3 million consisted of nonrecurring miscellaneous
items.

                                       13
<PAGE>

LOSS FROM CONTINUING OPERATIONS of $32.3 million, or $1.43 per diluted share,
included $14.5 million, or $.65 per diluted share, in special charges. Excluding
special charges, the loss from continuing operations was $17.8 million, or $.78
per diluted share, compared to 1997 earnings from continuing operations of $40.4
million, or $1.83 per diluted share. The loss was due to lower shipment volumes
for all products, particularly oilfield products, coupled with lower prices for
oilfield products partially offset by slightly higher prices for specialty
tubing products. Also, significantly decreased production volumes negatively
impacted operating margins as fixed and semi-fixed costs were absorbed by fewer
units of production.

EXTRAORDINARY ITEM of $7.4 million, or $.33 per diluted share, was realized on
the gain from cancellation of all future obligations under the Coal Industry
Retiree Health Benefit Act of 1992 (Act). During 1997 extraordinary items
totaling a net gain of $0.9 million, or $.04 per diluted share, consisted of a
gain of $2.0 million for the downward adjustment of obligations under the Act,
partially offset by an extraordinary prepayment charge of $1.1 million on the
refinancing of Steel's credit facility.

NET LOSS of $24.9 million, or $1.10 per diluted share, included special charges
of $14.5 million which were reflected in the loss from continuing operations of
$32.3 million, or $1.43 per diluted share, and partially offset by an
extraordinary gain of $7.4 million, or $.33 per diluted share.

1997 COMPARED WITH 1996

NET REVENUES of $654.3 million increased 19.2% over 1996. Net revenues from
oilfield products improved 22.4% to $454.1 million in 1997. Shipment volumes and
prices were up from 1996 levels by 16.0% and 5.5%, respectively. Demand for
Steel's OCTG rose as land based drilling increased in 1997. This was reflected
in the average domestic rig count which increased to 943 in 1997 from 779 in
1996. Demand was also favorably impacted by the reduction in imported OCTG
resulting from the continuation of duties imposed on products from certain
countries.

Specialty tubing products revenues increased by 17.5% to $129.0 million from
higher shipment volumes with flat prices. Shipment volumes were up 18.0% due to
additional automotive sales, robust construction activity, and strengthening
demand in the overall economy. Steel achieved higher shipments with new capacity
from the expansion of its specialty tubing facilities in late 1996.

Flat rolled and other tubular products net revenues were up 4.4% to $71.2
million due to higher realized prices with flat shipment volumes.

GROSS EARNINGS improved 33.2% to $64.2 million in 1997 from $48.2 million in
1996. The improvement was due to higher shipments of oilfield and specialty
tubing products combined with small price increases for oilfield products and
flat rolled steel. Increased production volumes also resulted in improved gross
margins as raw material costs were essentially unchanged from 1996.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES increased to $19.6 million from
$16.4 million in 1996 due to additional selling expenses associated with higher
sales and continued modernization of computer systems.

INTEREST INCOME decreased $1.4 million in 1997 from 1996 to $3.0 million
primarily due to usage of $25.0 million of invested funds in January to buy the
remaining minority interest in Steel.

INTEREST EXPENSE of $6.6 million was $0.2 million less than 1996 due to the
conversion of Lone Star's $50.0 million subordinated debentures at the end of
August into 2.1 million shares of Lone Star's common stock.

OTHER INCOME, NET. Net other income of $0.3 million and $0.1 million for 1997
and 1996, respectively, consisted of nonrecurring miscellaneous items.

EARNINGS FROM CONTINUING OPERATIONS for 1997 improved to $40.4 million, or $1.83
per diluted share, from $24.9 million,

                                       14
<PAGE>

or $1.19 per diluted share, in 1996. The improvement was due to higher shipment
volumes, small price increases for oilfield products and better gross margins.

EXTRAORDINARY ITEMS totaling $0.9 million, or $.04 per diluted share, reflect a
$1.1 million prepayment charge on the refinancing of Steel's revolving credit
facility and a $2.0 million gain related to reduction of prior reserves for
United Mine Worker's claims.

GAIN FROM DISCONTINUED OPERATIONS of $12.4 million, or $.57 per diluted share,
resulted from receipt of escrowed proceeds of $12.4 million from the prior sale
of American Federal Bank.

NET EARNINGS of $53.7 million, or $2.44 per diluted share, included earnings
from continuing operations of $40.4 million, extraordinary items of $0.9 million
and gain from discontinued operations of $12.4 million.

                        FINANCIAL CONDITION AND LIQUIDITY

At December 31, 1998, Lone Star had available cash and cash equivalents,
short-term investments, and marketable securities totaling $33.0 million.

Also at year-end, Steel had a $100.0 million revolving credit facility, under
which it had $46.0 in borrowings and $12.4 million in availability after
reduction for borrowings and outstanding letters of credit. Under this facility,
Steel could borrow an amount based on a percentage of eligible accounts
receivable and inventories, reduced by outstanding letters of credit. The total
available borrowing base was $58.4 million at December 31, 1998. Interest was
payable under one of two rate options: at the London Inter Bank Offer Rate
(LIBOR) plus an index which is based on quarterly debt ratio calculations or the
institution's prime lending rate plus 0.75%. At December 31, 1998, the rate was
8.28% and was indexed at 2.75% over LIBOR. The rate was 6.47% at December 31,
1997. Steel also paid an indexed rate on the unused portion of the credit
facility, which was 0.50% per annum at December 31, 1998. The term of the
agreement was through October 2002. The loan was secured by Steel's assets other
than real estate.

As a result of Steel's operating environment and resulting losses, the revolving
credit agreement was amended in December 1998 to provide for the aforementioned
borrowing base provisions, adjust the interest rate index and to amend various
restrictive financial covenants contained in the agreement.

This $100.0 million credit facility replaced another $75.0 million credit
facility from other lenders in October 1997. In connection with early
termination of the $75.0 million credit facility, a prepayment fee of $1.1
million was incurred and recognized as an extraordinary loss in the 1997
consolidated statement of operations.

On March 16, 1999, Steel refinanced its revolving credit facility with a new
three year $90.0 million revolving line of credit and a three year $10.0 million
term loan with a new lender. The new revolving credit facility is similar to the
refinanced facility in that Steel can borrow an amount based on a percentage of
eligible accounts receivable and inventories, reduced by outstanding letters of
credit. However, the borrowing capacity is increased under the new facility due
to higher borrowing base percentages and less restrictive limitations on the
inventory portion of the borrowing base. As of March 16, 1999, the total
available borrowing base including the term loan was approximately $83.3
million. At Steel's option, the interest rate is the prime lending rate plus
1.0% or the LIBOR plus 3.0%. Steel also pays a 0.375% per annum fee on the
unused portion of the credit facility. The term loan is repayable in quarterly
installments of $0.5 million, plus interest at the prime lending rate plus 1.5%
or the LIBOR plus 3.5%. Steel's assets other than real estate secure these
loans.

The loan agreements contain various restrictive covenants which require Steel to
meet specified quarterly financial ratios, including cash flow and net worth
measurements, which Steel anticipates achieving. Steel's ability to incur
additional indebtedness is also restricted under the agreements.

Steel requires capital primarily to fund general working capital needs and
capital expenditures. Principal sources of funds

                                       15
<PAGE>

include cash generated by operations, borrowings under Steel's revolving credit
facility and from Lone Star. Steel believes that its borrowing capacity under
the revolving credit agreement will provide the liquidity necessary to fund its
cash requirements during 1999.

Steel's operations are subject to restrictive environmental compliance and
permitting requirements of various governmental agencies that include the TNRCC
and the EPA. Steel believes that the cost of maintaining compliance with
environmental requirements will fall within its contemplated operating and
capital expenditure plans, averaging $1 - $2 million annually in the foreseeable
future.

Lone Star has no direct business operations other than Steel or significant
sources of cash other than from short-term investments or the sale of
securities. Lone Star is reimbursed by Steel for most of its operating costs as
provided by its cost- sharing agreement with Steel. Under Steel's new revolving
credit agreement, Lone Star's operating costs and Steel's portion of Lone Star's
consolidated taxes are the only funds that can be distributed to Lone Star.

Lone Star believes that reimbursements by Steel for most of its operating costs
and funds generated by cash and investments will be adequate to fund its cash
requirements during 1999.

YEAR 2000. In order to prepare Lone Star and Steel for the Year 2000, a plan has
been implemented detailing a process to ensure that its various computer systems
are or become Year 2000 compliant. This plan encompasses three primary areas:
business systems (both hardware and software), communications equipment, and
manufacturing equipment. The various stages in this process include assessment
(identifying systems which need change), remediation (making changes in the
software or hardware), verification (testing the changes), and implementation of
the Year 2000 compliant systems. Software applications for the business systems
were substantially completed through the verification stage at year-end and
implementation is scheduled to be completed during the first quarter of 1999.
The hardware applications related to business systems and the communication
equipment have been completed through the verification stage and substantially
implemented at the end of 1998, with complete implementation expected by the end
of the first quarter 1999. Approximately half of the manufacturing equipment had
been assessed at year-end 1998, with no changes required. The remaining
assessment is expected to be completed by April 1999 and, although no changes
are expected to be necessary, remediation, verification and implementation
processes will be developed at that time if needed.

This plan also entails assessing certain Year 2000 risks related to third party
relationships through communications with key suppliers and customers. The
processes described above will be performed on identified third party issues
that are correctable. For those suppliers and customers that may be identified
as a concern, such concerns will be addressed in Lone Star and Steel's
contingency plan. Lone Star and Steel have not identified the "most reasonably
likely worst case Year 2000 scenarios"; however, risks identified through the
process described above will be analyzed and evaluated. A contingency plan will
be developed in the second quarter of 1999 on how those identified risks will be
handled. The cumulative costs incurred through December 31, 1998 to achieve Year
2000 compliance are approximately $1.2 million, and are estimated to total $1.5
million upon completion in 1999.

ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Lone Star and its subsidiaries do not invest in commodities or foreign
currencies. Lone Star's investments in cash equivalents, short-term investments
and marketable securities, the weighted average maturity of which is less than
one year, are held to maturity. Therefore, interest rate risk is not considered
to be material. Information regarding Lone Star's investments is included in
Note A to the consolidated financial statements.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Directors of Lone Star Technologies, Inc. (Lone
Star):

We have audited the accompanying consolidated balance sheets of Lone Star (a
Delaware corporation) and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of earnings, shareholders' equity, and cash
flows for the three years ended December 31, 1998. These financial statements
and the schedules referred to below are the responsibility of Lone Star's
management. Our responsibility is to express an opinion on these financial
statements and schedules based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Lone
Star and subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for the three years ended December 31, 1998, in
conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole. The schedules listed in the
index to consolidated financial statements are presented for the purpose of
complying with the Securities and Exchange Commission's rules and is not a part
of the basic consolidated financial statements. These schedules have been
subjected to the auditing procedures applied in our audits of the basic
consolidated financial statements and, in our opinion, fairly state in all
material respects the financial data required to be set forth therein in
relation to the basic consolidated financial statements taken as a whole.

                          LONE STAR TECHNOLOGIES, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Lone Star Technologies, Inc. (Lone Star) is a management and holding company
whose one principal operating subsidiary, Lone Star Steel Company (Steel),
manufactures and globally markets oilfield products to the oil and gas drilling
industry, specialty tubing products to automotive, fluid power, and other
markets for various mechanical applications, and flat rolled steel and other
tubular products to domestic industrial markets.

ACCOUNTING POLICIES - NOTE A

PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include the
accounts of Lone Star and its subsidiaries. Intercompany transactions are
eliminated in consolidation. Gain from discontinued operations in 1997 relates
to the final settlement of the 1993 sale of American Federal Bank (AFB) (see
Note K).

CASH, INVESTMENTS, AND MARKETABLE SECURITIES. Lone Star's cash equivalents
include highly liquid investments in a fund consisting of U. S. government and
related agencies obligations with original maturities of less than three months.
Short-term investments consist of U. S. government and related agencies debt
obligations with maturities at purchase greater than three months and up to one
year. Marketable securities consist of U. S. government and related agencies
debt obligations with maturities at purchase greater than one year and up to two
years. Lone Star's total cash equivalents, short-term investments and marketable
securities, the weighted average maturity of which is less than one year, are
classified as held-to-maturity because Lone Star has the intent and ability to
hold them to maturity. At December 31, 1998, Lone Star's cash and cash
equivalents, short-term investments, and marketable securities, which had a
carrying amount that approximated market value, consisted of $33.0 million in U.
S. government and related agencies obligations at amortized cost.

INVENTORIES are stated at the lower of cost (principally last-in, first-out
"LIFO") or market value and include raw materials, labor, and overhead.

PROPERTY, PLANT, AND EQUIPMENT are stated at cost. Depreciation is provided on
the straight-line method over the estimated useful lives of depreciable assets.
Long-lived assets including property, plant, and equipment are periodically
evaluated to determine whether events or changes in circumstances have occurred
that indicate the remaining asset balances may not be recoverable and an
impairment loss should be recorded.

INCOME TAXES. Lone Star files a consolidated federal income tax return. Lone
Star utilizes an asset and liability approach for financial accounting and
income tax reporting. Deferred tax liabilities or assets are recognized for the
estimated future tax effects attributable to temporary differences and
carryforwards and are adjusted whenever tax rates or other provisions of income
tax statutes change.

MINORITY INTEREST. In January 1997, all of the outstanding common stock,
preferred stock, and warrants held by other shareholders of Steel were purchased
by Lone Star, making Steel a wholly owned subsidiary. This acquisition was
accounted for under the purchase method of accounting. The results for the year
ended December 31, 1996, were adjusted in the consolidated statements of
earnings to reflect the participation of minority ownership in Steel's earnings.

USE OF ESTIMATES. Preparation of the consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities, disclosures of contingent assets and liabilities, and the reported
amounts of revenues and expenses. Actual results could differ from those
estimates.

RECLASSIFICATIONS. Certain 1997 balances have been reclassified to conform to
current year presentation.

CURRENT OPERATING ENVIRONMENT AND BUSINESS SEGMENTS  - NOTE B

Effective January 1, 1998, Lone Star adopted SFAS No. 131, "Disclosure About
Segments of an Enterprise and Related Information." SFAS No. 131 requires
companies to identify their operating segments based upon the internal financial
information reported to the company's chief operating decision maker. Lone
Star's chief operating decision maker is its Chief Executive Officer (CEO).
Financial information reported to the CEO reflects three business segments:
oilfield products, specialty tubing products, flat rolled steel and other
tubular products, and corporate and other non-segments. The CEO evaluates the
performance of each segment based upon operating earnings (loss) as reported in
accordance with generally accepted accounting principles and operational data.
The accounting policies of the segments are the same as those described in the
summary of accounting policies in Note A to the consolidated financial
statements except that Lone Star allocates certain assets, capital expenditures,
depreciation and other items common to all segments based upon segment revenues
or manufacturing costs.

Oilfield products are comprised of casing, tubing, and line pipe, that are
manufactured and marketed globally to the oil and gas drilling industry.
Specialty tubing products consist of Drawn Over Mandrel (DOM) tubing and
as-welded tubing that are manufactured and marketed globally to automotive,
fluid power, and other markets for various mechanical applications. Flat rolled
steel and other tubular products and services are manufactured and provided to
general industrial markets.

Sales of oilfield products are greatly impacted by the level of domestic oil and
gas drilling, which in turn is primarily dependent on oil and natural gas
prices. Because of the volatility of oil and gas prices and drilling activity as
well as other factors, such as competition from foreign imports, demand for
these steel products can be subject to significant fluctuations.

Steel's specialty tubing products segment includes two product groups: DOM
tubing and as-welded tubing. Specialty tubing consists of a wide array of
high-quality, custom-made steel tubular products requiring critical tolerances,
precise dimensional control, and special metallurgical properties. Specialty
tubing is used in a wide range of industrial applications and, therefore, demand
is sensitive to general economic conditions.

Steel's participation in the flat rolled steel commodity market to some extent
involves its excess capacity for flat rolled steel as related to the manufacture
of its oilfield and specialty tubing products and certain cost considerations
associated with its total manufacturing operations. Steel's flat rolled steel
commodity market is generally concentrated in the southwestern region of the
United States. Flat rolled steel is sold in highly competitive markets, with
price, quality, and availability primarily determining customer purchase
decisions.

The corporate segment is responsible for financial operations including
investing and managing financial assets, financing of product purchases,
shareholder relations, and assessing and evaluating strategic alternatives.

Steel's primary manufacturing facilities are located in East Texas. Raw
materials and supplies, principally steel slabs and steel coils used in the
manufacture of Steel's products have historically been readily available from
various competitive sources. The manufacture of Steel's products uses several
common facilities and shares administrative support. Accordingly, the segment
information contains certain costs and assets which are allocated and may not
reflect each line of business as if it were operated separately.

Steel's principal market is domestic, although sales are also made into
international markets. The majority of sales of tubular products occur through
networks of sales distributors, although some tubular product sales and most
flat rolled steel sales are made directly to end users. Sales to the largest
oilfield products customer were $29.9 million or approximately 7% of net
revenues in 1998, $83.1 million or 13% in 1997, and $53.2 million or 10% in
1996. Sales to another significant customer of flat rolled steel and other
tubular products were $43.3 million or 10%, $53.3 million or 8%, and $49.1
million or 9% of net revenues for 1998, 1997, and 1996, respectively. Direct
foreign revenues as a percent of total revenues were approximately 8% of the
total in 1998 and 9% in 1997 and 1996.

Of Steel's total active labor force, 52% are represented by three collective
bargaining agreements. The majority of union workers are represented by the
United Steelworkers of America under a contract signed in May 1996, which
expires on May 31, 2001, with a provision to reopen the contract for wages but
not other benefit or work conditions after May 31, 1999. The two other
agreements expire in 2000.

For the year ended December 31, 1998, Lone Star had net sales of $432.4 million
and an operating loss of $30.1 million, which included $14.5 million of special
charges. This compares to net sales of $654.3 million and an operating profit of
$44.6 million for 1997. The most significant reason for these declines was the
decrease in demand for oilfield products, which was driven by a decrease in the
number of domestic rigs drilling for oil and natural gas during 1998. At
year-end, 621 rigs were active compared to 1,007 at the end of 1997. Steel's
open orders for OCTG at December 31, 1998, were down 78% from the prior year due
to the decline in drilling activity and high industry-wide OCTG inventories.
This reduced drilling activity was principally caused by declining crude oil
prices that reached recent historic lows in late 1998 and lower gas prices. In
addition, demand decreased for specialty tubing products and flat rolled steel
due to reduced demand for specialty tubing in certain Asian economies and
increased competition from an influx of inexpensive foreign coils into the
domestic market. Substantial uncertainty exists regarding the future levels of
oil and gas prices and related drilling activity. Therefore,

                                       25
<PAGE>

no assurance can be given regarding the extent of future demand for Steel's OCTG
products, or that profitability can be achieved until these markets improve.

Steel requires capital primarily to fund general working capital needs and
capital expenditures. Principal sources of funds include cash generated by
operations, borrowings under Steel's revolving credit facility (Note F) and from
Lone Star. Steel believes that its borrowing capacity under the revolving credit
agreement will provide the liquidity necessary to fund its cash requirements
during 1999.

Lone Star has no direct business operations other than Steel or significant
sources of cash other than from short-term investments or the sale of
securities. Lone Star is reimbursed by Steel for most of its operating costs as
provided by its cost-sharing agreement with Steel. Under Steel's new revolving
credit agreement, Lone Star's operating costs and Steel's portion of Lone Star's
consolidated taxes are the only funds that can be distributed to Lone Star.

Lone Star believes that reimbursements by Steel for most of its operating costs
and funds generated by cash and investments will be adequate to fund its cash
requirements during 1999.

SPECIAL CHARGES - NOTE C

In response to late 1998 and expected 1999 market conditions, Steel has
restructured and downsized its operations. The lower operating rates resulted in
the need to reduce employment levels and initiate other actions. As a result of
these actions, special charges of $14.5 million have been recognized in the 1998
consolidated statement of operations, which include the following items in
millions:

                                                                                             -------
           Total special charges                                                               $14.5
</TABLE>

Certain facilities are expected to permanently reduce or eliminate their
operations, relying instead on alternative production or procurement methods.
This includes a reduction in the production level of the electric-arc furnace
steelmaking facilities, with heavier reliance to be placed on purchased steel in
coil and slab form. Additionally, some finishing processes and infrastructure
utility services have or are expected to be permanently abandoned and be
completely replaced through outside procurement. These actions triggered an
assessment of the recoverability of the asset carrying costs and the resulting
recognition of an impairment loss. The determination of the impairment loss was
based on an evaluation of future cash flows from operation of the steelmaking
facilities and estimated salvage values of the steelmaking facilities and those
facilities to be abandoned. The net book value of these assets, which included
property, plant and equipment supplies inventory, totaled $12.6 million, of
which $8.1 million is included in the special charges.

Certain existing supplier contracts are also being renegotiated or cancelled to
accommodate the lower operating levels. Estimated costs of $4.4 million
associated with renegotiating or cancelling these obligations that will provide
no future benefit have been included in the special charges and accrued at
December 31, 1998.

Steel has terminated employees or identified certain positions for elimination
as of December 31, 1998. Payments made to terminated employees are based on
Steel's standard severance package. Total employee severance costs included in
special charges totaled $2.0 million, of which $1.1 million had been paid by
December 31, 1998.

of America ("UMWA") retirees and eligible dependents. A liability had been
recorded for the total estimated future payments related to this Act. During
1998, Steel's obligations under the Act were cancelled resulting in a $7.4
million extraordinary gain. During 1997, the estimated UMWA liability was
adjusted downward resulting in a $2.0 million extraordinary gain.

Accounts receivable is stated net of allowance for doubtful accounts of $1.4
million both at December 31, 1998 and 1997.

Approximately $110.8 million and $140.8 million of total inventories before LIFO
valuation reserves were accounted for on the LIFO basis at December 31, 1998 and
1997, respectively. During 1998, Steel experienced a reduction of inventory
which resulted in the depletion of previous inventory LIFO layers, the financial
effect of which was not significant to net reported results of operations.
Non-LIFO inventories are stated at the lower of average cost or market. The
total inventories before LIFO valuation reserves approximates replacement cost
of the inventories.

DEBT - NOTE F

YEAR-END BALANCES. Steel's long-term debt of $46.0 million and $43.0 million at
December 31, 1998 and 1997, respectively, consisted of borrowings under a $100.0
million revolving credit facility. The fair value of Steel's long-term debt at
December 31, 1998 and 1997, approximated the recorded amounts. Under this
facility, Steel could borrow an amount based on a percentage of eligible
accounts receivable and inventories, reduced by outstanding letters of credit.
The available borrowing base was $58.4 million at December 31, 1998. Interest
was payable under one of two rate options: at the London Inter Bank Offer Rate
(LIBOR) plus an index which is based on quarterly debt ratio calculations or the
institution's prime lending rate plus 0.75%. At December 31, 1998, the rate was
8.28% and was indexed at 2.75% over LIBOR. The rate was 6.47% at December 31,
1997. Steel also paid an indexed rate on the unused portion of the credit
facility, which was 0.50% per annum at December 31, 1998. The term of the
agreement was through October 2002. The loan was secured by Steel's assets other
than real estate.

As a result of Steel's operating environment and resulting losses described in
Note B, the revolving credit agreement was amended in December 1998 to provide
for the aforementioned borrowing base provisions, adjust the interest rate index
and to amend various restrictive financial covenants contained in the agreement.

This $100.0 million credit facility replaced another $75.0 million credit
facility from other lenders in October 1997. In connection with early
termination of the $75.0 million credit facility, a prepayment fee of $1.1
million was incurred and recognized as an extraordinary loss in the 1997
consolidated statement of operations.

SUBSEQUENT REFINANCING IN 1999. On March 16, 1999, Steel refinanced its
revolving credit facility with a new three year $90.0 million revolving line of
credit and a three year $10.0 million term loan with a new lender. The new
revolving credit facility is similar to the refinanced facility in that Steel
can borrow an amount based on a percentage of eligible accounts receivable and
inventories, reduced by outstanding letters of credit. However, the borrowing
capacity is increased under the new facility due to higher borrowing base
percentages and less restrictive limitations on the inventory portion of the
borrowing base. As of March 16, 1999, the amount of the total available
borrowing base including the term loan was approximately $83.3 million. At
Steel's option, the interest rate is the prime lending rate plus 1.0% or the
LIBOR plus 3.0%. Steel also pays a 0.375% per annum fee on the unused portion of
the credit facility. The term loan is repayable in quarterly installments of
$0.5 million, plus interest at the prime lending rate plus 1.5% or the LIBOR
plus 3.5%. Steel's assets other than real estate secure these loans.

The loan agreements contain various restrictive covenants which requires Steel
to meet specified quarterly financial ratios, including cash flow and net worth
measurements, which Steel anticipates achieving. Steel's ability to incur
additional

                                       28
<PAGE>

indebtedness is also restricted under the agreements, and Steel can repay a 
$25.0 million loan from Lone Star only if certain conditions are met after 
March 12, 2002. In addition, Steel's ability to pay cash dividends is 
prohibited by the agreement. At December 31, 1998, Lone Star's equity in the 
net assets of Steel was $132.0 million.

Cash paid for interest during 1998, 1997, and 1996 was $5.4 million, $9.4
million, and $7.2 million, respectively. Interest of $0.4 million was
capitalized into property, plant, and equipment during 1996.

NET EARNINGS PER SHARE - NOTE G

Basic earnings per share is computed by dividing net income by the weighted
average number of shares of common stock. The numbers of shares used to compute
basic earnings per share in 1998, 1997, and 1996 were approximately 22.5
million, 21.5 million, and 20.6 million, respectively. Diluted earnings per
share is computed by dividing net income by the weighted average number of
shares of common stock and other dilutive securities. The number of shares used
to compute diluted earnings per share in 1998, 1997, and 1996 were approximately
22.5 million, 22.1 million, and 20.9 million, respectively.

INCOME TAXES - NOTE H

There was no current income tax expense in 1998. Current income tax expense was
recognized for federal alternative minimum taxes of $0.9 million in 1997 and
$0.6 million in 1996. Cash paid for income taxes was $0.3 million in 1998, $1.3
million in 1997, and none in 1996. There was no deferred income tax expense or
benefit for 1998, 1997, or 1996. A reconciliation of computed income taxes to
actual income taxes follows:

At December 31, 1998, Lone Star had federal tax net operating loss carryforwards
(NOL's) of approximately $245.6 million, a portion of which may be related to
AFB and subject to an agreement with the Federal Deposit Insurance Corporation
(FDIC) whereby Lone Star may be required to pay the FDIC for certain tax
benefits. If not utilized, the NOL's will expire between years 2003 and 2013,
and their future availability may be limited if Lone Star or a member of the
consolidated group experiences an ownership change of more than 50 percentage
points, as defined by IRS regulations. Lone Star's common stock is publicly
traded, and management cannot assure that future trading will not result in an
ownership change, as defined by IRS regulations, which would limit availability
of the NOL's. Due to these uncertainties regarding possible utilization of NOL's
and the sensitivity of Steel's earnings to the level of domestic drilling
activity, valuation allowances were recorded to fully reserve the computed net
deferred tax assets.

EMPLOYEE BENEFIT PLANS - NOTE I

DEFINED CONTRIBUTION PLANS. Lone Star and Steel have defined contribution plans
available to substantially all full-time employees under which participants can
make voluntary pretax contributions. For nonbargaining unit employees, Lone Star
and Steel make matching contributions within specified limits. Steel makes
contributions at rates specified under collective agreements for its bargaining
unit employees. Lone Star and Steel contributions totaled $1.3 million in 1998,
$1.5 million in 1997, and $0.8 million in 1996.

STOCK OPTION PLAN. Lone Star has a long-term incentive plan which provides for
the issuance of up to 2,700,000 shares of common stock to key employees and
outside directors through the granting of incentive (the right to grant further
incentive options expired in 1995) and nonqualified stock options, stock
appreciation rights, restricted stock grants, and performance unit grants. The
option price is the average of the high and low market price on the date of the
grant. Options are generally exercisable for ten years with one-fourth of the
shares becoming exercisable on the one-year anniversary of the grant date and an
additional one-fourth becoming exercisable on the same anniversary date over the
next three years. If the optionee's employment is terminated under certain
circumstances after a change of control of Lone Star occurs before an option's
fourth anniversary, the option may be exercised in full earlier. Also,
accelerated vesting of options can occur upon death or retirement from
employment of an option holder. Following is a summary of stock option activity
during 1998, 1997, and 1996:

At December 31, 1998, 617,275 shares were available for grant and 450,625 shares
were exercisable.

The weighted average fair value per option granted in 1998, 1997, and 1996 was
$14.28, $9.72, and $5.91, respectively. The fair value of each option grant is
estimated on the date of grant using the Black-Scholes option pricing model with
the following weighted average assumptions for grants in 1998, 1997, and 1996,
respectively: risk-free interest rates of 5.60%, 6.36%, and 5.73%; volatility of
48.83%, 47.94%, and 54.4%; and expected lives of five years for all 1998, 1997,
and 1996 option grants with payment of no dividends.

Lone Star accounts for this plan under APB Opinion No. 25, under which no
compensation cost has been recognized. Had compensation cost for this plan been
determined consistent with SFAS No. 123, net income and earnings per share would
have been reduced to the following pro forma amounts:

Because the SFAS No. 123 method of accounting has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

DEFINED BENEFIT PENSION AND HEALTH CARE PLANS. Steel has three defined benefit
pension plans covering a substantial portion of its bargaining unit employees.
Retirement benefits are based on years of service at progressively increasing
flat- rate amounts. A special initial lump-sum pension payment equal to 13 weeks
of vacation pay is also paid following retirement. Steel funds the minimum
required contributions each year as required by applicable regulations.

During 1996, the largest of the three pension plans was amended so that new
employees do not participate in the defined benefit plan. During 1998, the other
two plans were similarly amended. New employees are eligible to participate in
one of the defined contribution retirement plans, as are substantially all other
employees. The amendments also provided for increased benefits to newly retiring
plan participants.

Steel also sponsors an unfunded defined benefit postretirement health care plan
for eligible bargaining unit employees and a limited number of other retirees
eligible under special early retirement programs. These health care plan
benefits are limited to eligible retirees and their spouses until age 65, at
which time coverage terminates. Certain other postretirement benefits, primarily
life insurance are also provided. The anticipated costs of these postretirement
benefits are accrued over the employees' years of service.

</TABLE>

In determining the benefit obligation, weighted average discount rates of 6.5%,
7.0%, and 7.5% were used for 1998, 1997, and 1996, respectively. Other
assumptions utilized for all three years included a 9.0% expected long-term rate
of return on plan assets and a 4.0% annual increase in the compensation rate.

Assumed health care cost trend rates have a significant effect on the amounts
reported for the health care plans. The annual rate of increase in the per
capita costs of covered health care benefits is assumed to decrease gradually
from 8.0% to an ultimate trend rate of 6.0% by the year 2004. Increasing the
assumed medical cost trend rates by one percentage point in each year would have
resulted in a $1.4 million increase in the benefit obligation as of December 31,
1998 and a $0.2 million increase in the aggregate of the service cost and
interest cost components of net periodic benefit expense for 1998. A 1.0%
decrease in the assumed trend rates would have resulted in a $1.2 million
decrease in the benefit obligation and a $0.2 million decrease in expense.

$3.9 million, and $2.7 million for 1998, 1997, and 1996, respectively.

COMMITMENTS AND CONTINGENCIES - NOTE J

Steel has various commitments for the purchase of raw materials, certain tubular
goods, supplies, services, and energy arising in the ordinary course of
business. The majority of these commitments are for a period of less than one
year.

Steel's operations are subject to numerous environmental laws. The three major
areas of regulation are air quality, water quality, and solid and hazardous
waste management. The primary governmental oversight agencies include the Texas
Natural Resource Conservation Commission and the Environmental Protection
Agency. Steel has agreements with these agencies to conduct numerous
environmental studies and to develop plans to ensure continuous compliance with
applicable laws and regulations. Steel is engaged in various ongoing
environmental studies, monitoring programs, and capital projects. Estimated
expenditures for certain remediation programs are included in accrued
liabilities and other noncurrent liabilities as shown in Note D and are computed
on a non-discounted basis. Steel believes that its environmental expenditures
will continue to fall within its contemplated operating and capital plans.

Steel leases equipment under various operating leases. Rental expense totaled
$3.7 million, $3.9 million, and $3.7 million in 1998, 1997, and 1996,
respectively. Future minimum lease payments under noncancellable operating
leases are as follows: 1999, $1.4 million; 2000, $1.1 million; 2001, $0.6
million; 2002, $0.5 million; 2003, $0.4 million; and thereafter, $0.5 million.

Lone Star and its subsidiaries are parties to a number of lawsuits and
controversies which are not discussed herein. Management of Lone Star and its
operating companies, based upon their analysis of known facts and circumstances
and reports from legal counsel, does not believe that any such matter will have
a material adverse effect on the results of operations or financial condition of
Lone Star and its subsidiaries, taken as a whole.

EXTRAORDINARY ITEMS AND GAIN FROM DISCONTINUED OPERATIONS - NOTE K

During 1992, The Coal Industry Retiree Health Benefit Act of 1992 ("Act")
created a benefit plan fund to provide medical and death benefits to certain
United Mine Workers of America ("UMWA") retirees and eligible dependents. In
1993, Steel recorded a liability for the total estimated future payments related
to this Act. During 1997, the estimated liability was adjusted downward,
resulting in an extraordinary gain of $2.0 million. During 1998, as a result of
a decision by the United States Supreme Court, Steel was relieved from making
payments under the Act. Accordingly, the remaining UMWA liability

                                       33
<PAGE>

(Note D) was reversed in 1998, resulting in a $7.4 million extraordinary gain.
In addition to the $2.0 million UMWA liability adjustment in 1997, an
extraordinary loss of $1.1 million was recognized for the early prepayment fee
in connection with the refinancing of Steel's revolving credit facility in 1997
(Note F), resulting in a net extraordinary gain of $0.9 million for 1997. There
were no income tax effects recognized for these extraordinary items.

In November 1993, Lone Star sold the stock of AFB, one of its operating
subsidiaries. The sale price was $155.7 million; of that, Lone Star received
$135.7 million in cash on the sale date. Additional payments were received of
$5.0 million in November 1994 and $12.4 million in August 1997, and recognized
as gains from discontinued operations. There were no income tax effects
recognized for these items.

                                  QUALIFIED ACCOUNTS

     Upon delivery to the Agent of each Schedule of Accounts, the Agent shall
make a determination, in its sole discretion, as to which Accounts listed
thereon shall be deemed Qualified Accounts. An Account shall not be considered a
Qualified Account unless the Agent determines, in its sole discretion, that such
Account has met the following minimum requirements:

          (i)  the Account represents a complete bona fide transaction for goods
     sold and delivered or services rendered (but excluding any amounts in the
     nature of a service charge added to the amount due on an invoice because
     the invoice has not been paid when due) which requires no further act under
     any circumstances on the part of the applicable Loan Party to make such
     Account payable by the Account Debtor; the Account arises from an
     arm's-length transaction in the ordinary course of such Loan Party's
     business between such Loan Party and an Account Debtor which is not an
     Affiliate of any Loan Party or an officer, stockholder or employee of any
     Loan Party or any Affiliate of any Loan Party, or a member of the family of
     an officer, stockholder or employee of any Loan Party or any Affiliate of
     any Loan Party;

          (ii) the Account shall not (a) be or have been unpaid more than ninety
     (90) days from the invoice date, (b) be delinquent more than sixty (60)
     days, or (c) be payable by an Account Debtor (1) more than 50% of whose
     Accounts have remained unpaid for more than ninety (90) days from the
     invoice date or are delinquent more than sixty (60) days, or (2) whose
     Accounts constitute, in the Agent's determination, an unduly high
     percentage of the aggregate amount of all outstanding Accounts;

          (iii) the goods the sale of which gave rise to the Account were
     shipped or delivered or provided to the Account Debtor on an absolute sale
     basis and not on a bill and hold sale basis, a consignment sale basis, a
     guaranteed sale basis, a sale or return basis, or on the basis of any other
     similar understanding, and no part of such goods has been returned or
     rejected;

          (iv) the Account is not evidenced by chattel paper or an instrument of
     any kind;

          (v)  the Account Debtor with respect to the Account (a) is solvent,
     (b) is not the subject of any bankruptcy or insolvency proceedings of any
     kind or of any other proceeding or action, threatened or pending, which
     might have a materially adverse effect on its business, and (c) is not, in
     the sole discretion of the Agent, deemed ineligible for credit for other
     reasons (including, without limitation, unsatisfactory past experiences of
     any Loan Party or any of the Banks with the Account Debtor or
     unsatisfactory reputation of the Account Debtor);

          (vi) the Account Debtor is not located outside Canada or the
     continental United States of America, provided that if the Account Debtor
     is located in Canada, the


<PAGE>

     Account is supported by a letter of credit or FICA insurance deemed
     adequate and acceptable by the Agent;

          (vii) the Account Debtor is not the government of the United States of
     America, or any department, agency or instrumentality thereof, or (b) if
     the Account Debtor is an entity mentioned in clause (vii)(a), the Federal
     Assignment of Claims Act (or applicable similar legislation) has been fully
     complied with so as to validly perfect the Banks' Prior Security Interest
     to the Agent's satisfaction;

          (viii) the Account is a valid, binding and legally enforceable
     obligation of the Account Debtor with respect thereto and is not subject to
     any dispute, condition, contingency, offset, recoupment, reduction, claim
     for credit, allowance, adjustment, counterclaim or defense on the part of
     such Account Debtor, and no facts exist which may provide a basis for any
     of the foregoing in the present or future;

          (ix) the Account is subject to the Agent's and the Banks' Prior
     Security Interest and is not subject to any other Lien, claim, encumbrance
     or security interest whatsoever;

          (x)  the Account is evidenced by an invoice or other documentation and
     arises from a contract which is in form and substance satisfactory to the
     Agent;

          (xi) the applicable Loan Party has observed and complied with all laws
     of the state in which the Account Debtor or the Account is located which,
     if not observed and complied with, would deny to such Loan Party access to

     Inventory which is in transit and is so identified on the relevant Schedule
     of Inventory;

          (iv) the Inventory is not stored with a bailee, warehouseman,
     consignee or similar party unless the Agent has given its prior written
     consent and such Loan Party has caused such bailee, warehouseman, consignee
     or similar party to issue and deliver to the Agent, in form and substance
