ITEM 1.   BUSINESS

                                       GENERAL

Lone Star Technologies, Inc. (LST) 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.  LST's consolidated revenues are not seasonal.
However, Steel's sales of oilfield products are sensitive to the level of
domestic drilling activity, which is in turn dependent on the prices of oil and
natural gas.

LST was incorporated in Delaware in 1986 and became the holding company of
Steel, pursuant to Steel's merger with a wholly owned subsidiary of LST.  In
1988, LST acquired the stock of American Federal Bank (AFB), a federally
chartered savings bank.  During May 1991, a major creditor group received 19.5%
of the common stock of Steel, creating a minority interest in Steel.  In 1995,
LST 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 LST, making Steel a wholly owned subsidiary of LST.  In
November 1993, LST sold the stock of AFB.  During August 1997, LST 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.

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 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


                                          3
<PAGE>

ranges of OCTG diameters (2 1/16" to 20") and grades produced in the industry,
including grades that have been successfully used for drilling at depths of over
30,000 feet.

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 up 21% in 1997 from the
prior year, according to the average number of rigs operating in the United
States as measured by Baker Hughes.  Steel's open orders for OCTG at December
31, 1997, were down 21% from the prior year-end as distributors continued to
work down slightly higher inventory levels at the end of the year.
Approximately 6% of shipments in 1997 were used 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.

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 10% of Steel's line pipe shipments were exported in
1997.

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
1997, accounted for 17% and 12% of total tons shipped, respectively.  About 77%
of the oil and gas wells drilled in the United States in 1997 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.  Steel has expanded into other marketing agreements to sell
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 20% of Steel's revenues from oilfield products during 1997.

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 purchases steel slabs, scrap steel, and steel coils for use in the
manufacture of its products.  The availability of steel slabs to meet production
needs remained tight in 1997, and it was often necessary for Steel to commit to
purchase slabs   90 to 150 days prior to production.  Steel has secured
commitments from a major supplier to be provided most of its steel slab
requirements for 1998.  Steel's principal raw material for its internally
produced steel slabs is steel scrap, which is purchased in the spot market and
internally generated from Steel's operations.  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 a wide range of sizes and chemistries 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-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


                                          4
<PAGE>

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-Registered 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 16% of the apparent supply available to the
domestic OCTG market during 1997 and 14% during 1996 and 1995, as compared to
24% in 1994.  A reduction of imported OCTG 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 1997.  Because these
protective tariffs cover significant OCTG producing countries in Asia, the level
of imported OCTG has not substantially changed as a result of currency
devaluations and general slowdowns in certain Asian economies at the end of
1997.

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 range
in size from 7/8" to 15 1/2" in outside diameter 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 devices, machine parts, bearing
races, downhole pump barrels, and printing rollers.  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 largest domestic manufacturing capacity for DOM
tubing.  The use of the DOM manufacturing process enables Steel to achieve
higher critical tolerances and dimensional control than other processes.
Steel's 1,000,000 pound drawbench, the largest in the United States, also
enables Steel to manufacture larger diameter, heavier wall products and thus
access a broader market than its competitors.  Moreover, Steel is the only DOM
specialty tubing manufacturer in the U.S. that produces its own electric arc
furnace (EAF) steel, which allows for control of the complete manufacturing
process.  DOM specialty tubing order quantities are typically small (usually
less than 50,000 pounds) and made to exact customer specifications.  Steel's
integration of steelmaking and tube finishing allows for optimal inventory
control, combined with just-in-time customer delivery of tubes with special
steel chemistries and precise dimensional requirements.

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 up in
1997 due to strong automotive sales, construction activity, and general economic
conditions.  Open orders at year-end 1997 were 56% more than 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 1997 accounted
for 14% of total shipments.  Internationally, the majority of Steel's specialty
tubing is currently sold directly to end users.  Exports accounted for
approximately 26% and 19% of Steel's DOM specialty tubing shipments in 1997 and
1996, respectively.

RAW MATERIALS AND INVENTORIES.  Raw materials are readily available from
multiple sources.  Production is generally


                                          5
<PAGE>

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 purchases steel slabs, scrap steel, and coiled  steel for use in the
manufacture of its products.  The availability of steel slabs to meet production
needs remained tight in 1997, and it was often necessary for Steel to commit to
purchase slabs 90 to 150 days prior to production.  Steel has secured
commitments from a major supplier to be provided most of its steel slab
requirements for 1998.  Steel's principal raw material for its internally
produced steel slabs is steel scrap, which is purchased in the spot market and
internally generated from Steel's operations.  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.  The expansion allowed Steel to
ship 18% more tons in 1997 over 1996.  Based on generally available market data,
Steel believes it has the largest production capacity for DOM specialty tubing
products in the United States.

Steel is the only fully integrated DOM producer in the United States.  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.  The largest customer of Steel's flat rolled steel accounted for 80% of
Steel's flat rolled steel sales in 1997 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 8% of
Steel's total revenues for 1997.

RAW MATERIALS AND INVENTORIES.  Steel produces flat rolled steel from its
internally produced slabs and slabs purchased from unrelated companies.  The
availability of steel slabs to meet production needs remained tight in 1997, and
it was often necessary for Steel to commit to purchase slabs 90 to 150 days
prior to production.  Steel has secured commitments from a major supplier to be
provided most of its steel slab requirements for 1998.  Steel's principal raw
material used in the production of its slabs is steel scrap, which is purchased
in the spot market and internally generated from Steel's operations.  The price
of steel scrap can be volatile and is influenced 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.


                                          6
<PAGE>

OTHER PRODUCTS.  Steel markets its surplus and reject 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, 1997, LST and Steel had a total of 2,044 active employees, of
whom 1,390 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.  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 $58.1
million, $50.0 million, and $37.9 million for the years 1997, 1996, and 1995,
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 it can be
demonstrated that the state 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) and the federal air
quality program under the Clean Air Act.  The Texas air quality program also
requires all new or modified facilities that may emit any air contaminant to
obtain a permit which may impose limitations on emissions.  Texas has not yet
been delegated authority to implement the federal water quality program under
the Clean Water Act.  Therefore, dual federal and state water quality programs
exist in Texas, requiring companies such as Steel to obtain both a federal
permit and a state permit to discharge wastewater into state waters.  In
addition, Texas has state environmental programs that supplement and operate
independently of the federal environmental programs.  Texas has established its
own program for the regulation of municipal and industrial solid wastes under
the Texas Solid Waste Disposal Act.  Steel's operations generate wastes that are
regulated as industrial solid waste under this program.

AIR quality is governed by the federal Clean Air Act and the Texas Clean Air
Act.  The TNRCC has primary responsibility for implementing and enforcing the
federal law through the state program.  The Texas State Implementation Plan
implements, maintains, and enforces the National Ambient Air Quality Standards
established by the EPA, as well as the other federal air quality programs.
Recently, the TNRCC adopted rules implementing Title V of the federal Clean Air
Act, which requires subject sources to apply for a general operating permit.
Steel has submitted an abbreviated application for a general


                                          7
<PAGE>

operating permit, as required.  The TNRCC has not yet set a deadline for subject
sources within the steel industry to submit full applications.  Once the TNRCC
issues Steel a general operating permit, Steel will have additional record
keeping obligations.

Emission sources at Steel's facilities are currently regulated by a combination
of individual 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
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 permitting requirements.  Steel is
presently in substantial compliance with the conditions of its permits and
applicable standards.

WATER quality is governed by the federal Clean Water Act, implemented by the
EPA, and the state Water Code, implemented by the TNRCC.  Steel is required to
have two separate permits to discharge wastewater from each of its outfalls: a
National Pollutant Discharge Elimination System (NPDES) permit issued by the EPA
and a wastewater discharge permit issued by the TNRCC.  The regulatory emphasis
on wastewater is directed at the control of effluent toxicity.  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.

In the process of manufacturing low alloy carbon grade steel and fabricating
steel pipe and tube, Steel generates wastewater which contains certain
contaminants from the process.  Steel is authorized by both a state and a
federal permit to discharge its wastewater to either of two receiving water
bodies, Ellison Creek Reservoir or Big Cypress Creek.  Each permit contains
effluent limitations for the contaminants of concern that might be present in
Steel's wastewater.  The effluent limitations are usually the same in both
permits, but if not, the more stringent limitations determine the maximum
concentrations of contaminants that may be present in Steel's wastewater.  To
comply with these limitations, Steel treats its wastewater before discharge.
The permits require that Steel monitor the concentrations of the contaminants of
concern in its effluent on a regular basis and report the monitoring results to
the TNRCC and the EPA.

The only compliance issue for Steel is the effluent limitations for total lead
at its process discharge outfall.  Steel's state wastewater discharge permit was
renewed effective August 1, 1994, for a five-year term.  The effluent
limitations for total lead were less stringent for the first three years than
the remaining two years of the permit term because the TNRCC also issued an
order granting Steel a three-year variance from the Texas Surface Water Quality
Standards for dissolved lead.  The order was based on scientific evidence that
less stringent, site-specific water quality standards for dissolved lead were
appropriate for the receiving water bodies into which Steel discharges its
wastewater.  Thereafter, the TNRCC adopted, and the EPA approved, the
site-specific water quality standards for dissolved lead.  Before the temporary
variance expired on August 1, 1997, and in accordance with the terms of the
temporary variance, Steel submitted an application to the TNRCC for an amendment
to its wastewater discharge permit to modify the final effluent limitations for
total lead at its process discharge outfall.  Recently, the TNRCC provided to
Steel, for review, a draft proposed permit that contains effluent limitations
for total lead at that outfall based on the site-specific water quality
standards for dissolved lead.  The proposed effluent limitations for total lead
are less stringent than those that were authorized by the temporary variance.
Steel anticipates that the TNRCC will issue to Steel the final amended permit
within a few months.  Steel further anticipates that it will be able to comply
with all requirements of its state wastewater discharge permit as amended.

Steel's existing federal NPDES permit for wastewater discharges was scheduled to
expire in June 1995.  However, this permit continues in effect until the EPA
takes final action on a renewal NPDES permit.  On December 31, 1994, the EPA
published a notice of intent to issue Steel a renewal NPDES permit.  The draft
NPDES permit contained effluent limitations for total lead that are less
stringent than those in the existing NPDES permit.  The EPA based this
modification on the site-specific water quality standards for dissolved lead.
The only requirement in the draft NPDES permit on which the EPA and Steel could
not reach agreement was the inclusion of a whole effluent toxicity (WET) limit.
WET is measured by exposing freshwater organisms, such as fathead minnow larvae,
to various concentrations of effluent for seven days and then determining the
growth and survival of the test organisms.  A WET limit is a legally enforceable
permit limitation that is


                                          8
<PAGE>

based on the survival of the test organism in a stated concentration of the
effluent.  Steel opposed the inclusion of a WET limit in its renewal NPDES
permit, because its effluent contains naturally occurring bacteria that are
pathogenic to fathead minnow larvae.  These pathogenic bacteria interfere with
the WET tests.  Steel also later filed a Petition for Review challenging the EPA
final rule adopting the WET test methods for the reason that EPA did not address
in the methods the issue of how to account for adverse influences of pathogens
in the conduct of WET tests.  Steel and the EPA have been involved in settlement
negotiations to resolve both the Petition for Review and the NPDES permit issue.
Steel believes that it will be able to settle both matters favorably with the
EPA.

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 on-site management units.  Steel is
registered as a large quantity generator and only stores hazardous waste on-site
for periods less than ninety (90) days.  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 four
land-based RCRA waste management units and a fifth site which predates RCRA.  In
1996, Steel received TNRCC approval of a closure plan for the site not subject
to RCRA (a pond previously used for storing spent acid and a tarry waste).
Closure began in September 1997.  Two sites subject to RCRA (the main plant
landfill and a site that received air pollution sludge) have been closed as
hazardous waste landfills in accordance with requirements of RCRA and
corresponding state regulations.  These sites are subject to post-closure care
obligations, including groundwater monitoring, for up to thirty years.  Of the
remaining two sites, one has been closed by a combination of removal (clean
closed) and conversion to nonhazardous landfill and one has been clean closed,
in accordance with requirements of RCRA and corresponding state regulations.  In
1996, TNRCC accepted the closure certifications for all four units and released
the clean-closed and nonhazardous units from further RCRA requirements.  The
TNRCC will issue Steel a permit for the facilities requiring post-closure care.
Steel estimates the actual cost of RCRA post-closure care for the remaining
twenty-four years to be approximately $350,000.


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; six
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 LST's headquarters are located in leased facilities in
Dallas, Texas.

Steel's annual rated capacity approximates 480,000 slab tons, 1,250,000 flat
rolled tons, and 1,000,000 welded pipe tons.  Steel has access through marketing
arrangements and agreements with alliance mills to additional oilfield pipe
capacity of approximately 250,000 tons.  In 1997, the specialty tubing
facilities operated near 80% of capacity.  The rolling mills and pipe mills
generally operated at or above 90% of capacity, while the EAF's operated at
about 50% 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


                                          9
<PAGE>

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 LST and its
subsidiaries taken as a whole.

As of January 31, 1998, LST had approximately 4,200 common shareholders of
record.  LST has paid no dividends on its Common Stock since becoming a public
company.

On July 28, 1997, LST called for redemption of its $50.0 million principal
amount 8% convertible subordinated debentures due 2002.  By the end of August
1997, substantially all of the debentures were converted into LST common stock
increasing the total shares outstanding by 2.1 million.

During December 1997, LST purchased 0.5 million shares of its common stock to be
used as treasury stock under a Board of Directors approved plan to buy up to 1
million common shares.

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

                                       OVERVIEW

LST'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
and marketing 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.  OCTG represents over three-fourths of Steel's
oilfield products volume as measured in tonnage, and exports have ranged from
approximately 6% to 12% 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 1997, 1996, and 1995 were 943, 779, and 723,
respectively.  Demand is also affected by the amount of oilfield products
imported into this country as well as available industry inventories.  Imported
OCTG represented approximately 16% of the apparent supply in 1997 and 14% in
1996 and 1995, as compared to 24% in 1994.  A reduction of imported OCTG 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 1997.  Because these protective tariffs cover significant OCTG
producing countries in Asia, the level of imported OCTG has not substantially
changed as a result of currency devaluations and general slowdowns in certain
Asian economies at the end of 1997.  The effect of available inventory increased
in significance last year as OCTG mills operated near their full productive
capacity.  The volatility of oil and gas prices creates uncertainty with respect
to the timing and extent of increased activity in the energy sector.  This
affects customer confidence in the longer term outlook for energy prices and as
a result some drilling projects may be deferred.  However, domestic markets
strengthened considerably in 1997 as oil and gas prices were at levels needed to
justify additional exploration and production spending while efficiencies from
new oilfield technologies continued to lower costs associated with these
activities.

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 devices, and machine parts.

Specialty tubing is used in a wide range of industrial applications and,
therefore, demand is sensitive to general economic conditions.  Demand increased
during 1997 and open orders were up 56% at year-end as compared to year-end
1996. International shipments of DOM specialty tubing were 26%, 19%, and 15% of
shipments in 1997, 1996, and 1995, 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 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.

MANUFACTURING.  The manufacture of Steel's products is capital intensive.
Utilization rates rose significantly during 1997


                                          12

at Steel's manufacturing facilities.  Certain facilities were utilized in excess
of 90% of capacity for significant periods during 1997.  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 rolled steel provided by Steel into tubular products which provides Steel
access to additional manufacturing capacity.

Steel is under a capital expenditure program for the 1997 to 1998 period
totaling approximately $70.0 million.  This program is designed to improve
quality and lower costs and will be financed from operating cash flows and
available borrowings under Steel's revolving credit facility.

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.


                                          13
<PAGE>

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 LST's $50.0 million subordinated debentures at the end of August
into 2.1 million shares of LST'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, 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.


1996 COMPARED WITH 1995

NET REVENUES increased 28.9% to $549.0 million in 1996 from $425.8 million in
1995.  Net revenues of oilfield products increased 53.6% to $371.0 in 1996 from
$241.6 million in 1995.  Shipment volumes and prices increased in 1996 from 1995
levels by 50% and 2.4%, respectively, as the average domestic rig count
increased to 779 in 1996 from 723 in 1995.  As in 1995, demand for Steel's OCTG
was favorably impacted due to the reduction in imported OCTG resulting from the
continuation of protective tariffs on imported products from certain countries,
and by the types of drilling being conducted, such as deep water drilling in the
Gulf of Mexico, which increased the industry's requirements for larger diameter,
higher grade products for which Steel is most competitive.

Specialty tubing products net revenues decreased by 4.7% to $109.8 million in
1996 from $115.2 million in 1995 primarily attributable to weak demand from
steel service centers which was partially offset by increased demand from
automobile manufacturers.  For the specialty tubing product group, 1996 shipment
volume and price decreased by 2.0% and 2.7%, respectively.

Flat rolled and other tubular products net revenues were down 1.2% to $68.2
million in 1996 from $69.0 million in 1995 due to lower average selling prices.


                                          14
<PAGE>

GROSS EARNINGS improved 84.0% to $48.2 million in 1996 from $26.2 million in
1995.  This was attributable to increased shipments and prices of oilfield
products and a 12.2% decrease in the cost of steel slabs.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES increased to $16.4 million in 1996
from $14.6 million in 1995, primarily due to additional sales expenses as
product sales increased and additional spending to modernize management
information systems.

INTEREST INCOME was $1.4 million less in 1996 than in 1995 as short-term
interest rates were lower on average in 1996 than in 1995.

INTEREST EXPENSE for 1996 decreased $1.9 million from $8.7 million in 1995,
reflecting average lower borrowings in 1996 on Steel's revolving credit facility
compared to 1995.

OTHER INCOME, NET.  Net other loss in 1996 consisted of miscellaneous items
totaling of $0.1 million.  Net other income in 1995 was $2.4 million and
included $3.0 million from the gain on sale of approximately 9,400 acres of land
in East Texas.

EARNINGS FROM CONTINUING OPERATIONS AND NET EARNINGS for 1996 were both $24.9
million or $1.19 per diluted share.  For 1995, net earnings and earnings from
continuing operations were both $9.6 million or $0.46 per diluted share.


                          FINANCIAL CONDITION AND LIQUIDITY

At December 31, 1997, LST had available cash and cash equivalents, short-term
investments, and marketable securities totaling $39.5 million.

Also, at year-end Steel had a $100.0 million revolving credit facility, under
which it had $56.6 million of availability, after reduction for borrowings and
outstanding letters of credit.  This $100.0 million facility replaced another
$75.0 million credit facility from other lenders in October 1997.  Under the new
credit facility interest is payable under one of two rate options:  at the
London Interbank Offered Rate (LIBOR) plus an index which is based on quarterly
debt ratio calculations or the institution's prime lending rate.  At December
31, 1997, the rate was 6.47% and was indexed at 0.50% over LIBOR.  Steel also
pays an indexed rate on the unused portion of the credit facility, which at
December 31, 1997 was 0.15% per annum.  The term of the agreement is through
October 2002.  The revolving credit agreement also includes requirements to
maintain minimum net worth levels, meet certain financial ratios and restricts
Steel's ability to incur additional indebtedness.

On August 28, 1997, LST's $50.0 million 8% subordinated debentures were
converted into 2.1 million shares of LST common stock.

Steel requires capital primarily to fund general working capital needs and
capital expenditures.  Principal sources of funds include cash generated by
operations and borrowings.  Steel believes that funds generated by operations
and its borrowing capacity under the revolving credit agreement will provide the
liquidity necessary to fund its cash requirements during 1997.

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 - $3 million annually in the foreseeable
future.

LST and Steel have completed an assessment of certain year 2000 issues on
various computer related systems.  Necessary changes outlined in an
implementation plan for corrective actions are being made.  It is expected that
the required changes will be made by year 2000 to preclude any material adverse
consequences.  Corrective actions are estimated to cost $1 - $1.5 million in
1998 and are being funded primarily from ongoing computer systems operating
budgets.  LST and Steel are in


                                          15
<PAGE>

the process of conducting an additional assessment of certain year 2000 issues
on Steel's manufacturing equipment, time based operating equipment, and
significant suppliers, which will be completed in 1998.  It is anticipated that
corrective actions, if any, will be made by year 2000.

LST has no direct business operations other than Steel or significant sources of
cash other than from short-term investments or the sale of securities.  LST is
reimbursed by Steel for most of its operating costs as provided by its
cost-sharing agreement with Steel.  Under Steel's revolving credit agreement,
funds can be distributed to LST from unrestricted net worth, which at December
31, 1997 was $54.7 million.  Unrestricted net worth increases by 50% of Steel's
future net earnings less distributions.  At 1997 year-end, restricted net worth
was $108.4 million.

LST periodically purchases steel slabs which are consigned to Steel for use in
its production process and thereby affords Steel somewhat longer payment periods
for this raw material.  Steel pays LST as the slabs are used plus interest on
unpaid amounts.  During 1997, LST's slab purchases amounted to approximately
$113.3 million.

In November 1993, LST sold  the stock of AFB, one of its operating subsidiaries,
to Guaranty Federal Bank, F.S.B. (GFB).  The sale price was $155.7 million; of
that, LST received $135.7 million in cash on the date of the sale, $5.0 million
in November 1994, and $15.0 million was in escrow to pay for certain GFB claims
pursuant to the sale agreement.  During August of 1997, LST received $12.4
million from the escrow in final settlement of all outstanding claims and
recognized the same amount as gain from discontinued operations.


                           RECENT ACCOUNTING PRONOUNCEMENTS

LST will adopt SFAS No. 130, "Reporting Comprehensive Income" effective January
1, 1998.  SFAS No. 130 established standards for reporting and display of
comprehensive income and its components in a full set of general-purpose
financial statements.  Comprehensive income is defined as the total of net
income and all other non-owner changes in equity.  LST's only non-owner change
in equity at December 31, 1997, is a minimum pension liability adjustment.  Upon
adoption, comprehensive income and the cumulative other comprehensive income
will be reported in a consolidated statement of shareholders' equity which is
currently shown in Note D, to the consolidated financial statements.

LST will adopt SFAS No. 131, "Disclosure about Segments of An Enterprise and
Related Information", effective January 1, 1998.  This pronouncement changes the
requirements under which public businesses must report segment information.  The
objective of the pronouncement is to provide information about a company's
different types of business activities and different economic environments.
SFAS No. 131 will require companies to select segments based on their internal
reporting system.  LST's current segments, as reported herein, are consistent
with the company's internal reporting systems.  Therefore, adoption of this
pronouncement will not have a significant impact on LST's financial statement
disclosures.


                             FORWARD LOOKING INFORMATION

The statements included in this Annual Report regarding future financial
performance and results and the other statements that are not historical facts

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

LST and its subsidiaries do not invest in commodities or foreign currencies. 
LST'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 LST'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.
(LST):

We have audited the accompanying consolidated balance sheets of LST (a Delaware
corporation) and subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of earnings, shareholders' equity, and cash flows for
the three years ended December 31, 1997.  These financial statements and the
schedule referred to below are the responsibility of LST's management.  Our
responsibility is to express an opinion on these financial statements and
schedule 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 LST and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for the three years ended December 31, 1997, 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 schedule listed in the
index to consolidated financial statements is 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.  This schedule has been
subjected to the auditing procedures applied in our audits of the basic
consolidated financial statements and, in our opinion, fairly states 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.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Lone Star Technologies, Inc. (LST) is a management and holding company whose
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 LST 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 (see Note J).

CASH, INVESTMENTS, AND MARKETABLE SECURITIES.  LST's cash equivalents include
U.S. government and related agencies obligations and corporate debt instruments
rated A-1, P-1 or higher with original maturities of less than three months.
Short-term investments consist of U. S. government and related agencies debt
obligations and corporate debt instruments 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.  LST'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 LST has
the intent and ability to hold them to maturity.  At December 31, 1997, LST's
cash and cash equivalents, short-term investments and marketable securities,
which had a carrying amount that approximated market value, consisted of $30.0
million in U. S. government and related agencies obligations and $9.5 million in
corporate debt instruments 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 in accordance with Statement of Financial Accounting Standards No. 121
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.  LST files a consolidated federal income tax return.  LST 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 LST, making Steel a wholly owned subsidiary.  This acquisition was accounted
for under the purchase method of accounting.  Prior to 1997, minority ownership
in Steel was included in the liabilities section of LST's consolidated balance
sheets, and results for the years ended December 31, 1996 and 1995 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.


                                          22
<PAGE>

RECLASSIFICATIONS.  Certain 1996 balances have been reclassified to conform to
current year presentation.

RECENT ACCOUNTING PRONOUNCEMENTS.  LST will adopt SFAS No. 130, "Reporting
Comprehensive Income" effective January 1, 1998.  SFAS No. 130 established
standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements.  Comprehensive income is
defined as the total of net income and all other non-owner changes in equity.
LST's only non-owner change in equity at December 31, 1997, is a minimum pension
liability adjustment.  Upon adoption, comprehensive income and the cumulative
other comprehensive income will be reported in a consolidated statement of
shareholders' equity which is currently shown in Note D, to the consolidated
financial statements.

LST will adopt SFAS No. 131, "Disclosure about Segments of An Enterprise and
Related Information", effective January 1, 1998.  This pronouncement changes the
requirements under which public businesses must report segment information.  The
objective of the pronouncement is to provide information about a company's
different types of business activities and different economic environments.
SFAS No. 131 will require companies to select segments based on their internal
reporting system.  LST's current segments, as reported herein, are consistent
with the company's internal reporting systems.  Therefore, adoption of this
pronouncement will not have a significant impact on LST's financial statement
disclosures.

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 both 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.


                                          24

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.

Steel's primary manufacturing facilities are located in East Texas.  Raw
materials and supplies, principally scrap steel, 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 approximately 13% of net revenues in 1997, and
10% in both 1996, and 1995.  Sales to another significant customer of flat
rolled steel and other tubular products were approximately 8%, 9%, and 12% of
net revenues for 1997, 1996, and 1995, respectively.  Direct foreign revenues as
a percent of total revenues were approximately 9% of the total in 1997, 1996,
and 1995.

Of Steel's total labor force, 68% 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.

LST and Steel have completed an assessment of certain year 2000 issues on
various computer related systems.  Necessary changes outlined in an
implementation plan for corrective actions are being made.  It is expected that
the required changes will be made by year 2000 to preclude any material adverse
consequences.  Corrective actions are estimated to cost $1 - $1.5 million in
1998 and are being funded primarily from ongoing computer systems operating
budgets.  LST and Steel are in the process of conducting an additional
assessment of certain year 2000 issues on Steel's manufacturing equipment, time
based operating equipment, and significant suppliers, which will be completed in
1998.  It is anticipated that corrective actions, if any, will be made by year
2000.

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.  Steel is required to pay
premiums assessed annually under the Act for the benefit of former employees who
worked in Steel's now-discontinued coal mining

operations.  A liability has been recorded for the total estimated future
payments related to this Act.  Steel is making these payments under protest.
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, 1997 and 1996. Approximately $140.8 million and
$116.8 million of total inventories before LIFO valuation reserves were
accounted for on the LIFO basis at December 31, 1997 and 1996, respectively.
Non-LIFO inventories are stated at the lower of average cost or market.  The
total inventories before LIFO valuation reserves approximate replacement cost of
the inventories.

On July 28, 1997, LST called for redemption of its $50.0 million principal
amount 8% convertible subordinated debentures due 2002.  By the end of August
1997, substantially all of the debentures were converted into LST common stock,
increasing the total shares outstanding by 2.1 million.

At December 31, 1997, Steel had a $100.0 million revolving credit facility,
under which it had $56.6 million of availability after reduction for borrowings
and outstanding letters of credit.  This $100.0 million facility replaced
another $75.0 million credit facility from other lenders in October 1997.  A
$1.1 million prepayment penalty was recognized as an extraordinary item on
retirement of the old credit agreement (see Note J).  Under the new credit
arrangement interest is payable under one of two rate options:  at the London
Interbank Offered Rate (LIBOR) plus an index which is based on quarterly debt
ratio calculations or the institution's prime lending rate.  At December 31,
1997 the rate was 6.47% and was indexed at 0.50% over LIBOR.  Steel also pays an
indexed rate on the unused portion of the credit facility, which at December 31,
1997 was 0.15% per annum.  The term of the agreement is through October 2002 and
it is collateralized by the assets of Steel excluding real property.  Other
requirements include meeting minimum net worth levels and certain financial
ratios, and restrictions on Steel's ability to incur additional indebtedness.
Under the agreement, Steel can distribute funds to LST from unrestricted net
worth, which at December 31, 1997 was $54.7 million.  Unrestricted net worth
increases by 50% of LSS's future net earnings, less distributions.  At 1997 year
end, restricted net worth of Steel was $108.4 million.

Cash paid for interest during 1997, 1996, and 1995 was $9.4 million, $7.2
million, and $8.9 million, respectively.  Interest of $0.4 million was
capitalized into property, plant, and equipment during 1996.


NET EARNINGS PER SHARE - NOTE F

During 1997 LST adopted SFAS No. 128, "Earnings Per Share."  Under SFAS No. 128
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 1997, 1996, and 1995 were approximately 21.5
million, 20.6 million, and 20.4 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 1997, 1996, and 1995 were approximately
22.1 million, 20.9 million, and 20.6 million, respectively.


INCOME TAXES - NOTE G

There was a current income tax expense for federal alternative minimum tax of
$0.9 million in 1997, $0.6 million in 1996, and


                                          28

none in 1995.  Cash paid for income taxes was $1.3 million in 1997, and none in
1996 and 1995.  There was no deferred income tax expense or benefit for 1997,
1996, or 1995.  A reconciliation of computed income taxes to actual income taxes

At December 31, 1997, LST had federal tax net operating loss carryforwards
(NOL's) of approximately $223.1 million, a portion of which may be related to
AFB and subject to an agreement with the Federal Deposit Insurance Corporation
(FDIC) whereby LST may be required to pay the FDIC for certain tax benefits.  If
not utilized, the NOL's will expire between years 2002 and 2010, and their
future availability may be limited if LST or a member of the consolidated group
experiences an ownership change of more than 50 percentage points, as defined by
IRS regulations.  LST's common stock is publicly traded, and management cannot
assure that future trading will not result in an ownership change, as defined,
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 H

DEFINED CONTRIBUTION PLANS.  LST 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, LST and
Steel make matching contributions within specified limits.  Steel makes
contributions at rates specified under collective agreements for its bargaining
unit employees.  Steel and LST contributions totaled $1.5 million in 1997, $0.8
million in 1996, and $0.7 million in 1995.

STOCK OPTION PLAN.  LST 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 a change of control of LST 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 1997, 1996, and 1995:

At December 31, 1997, 847,775 shares were available for grant and 354,625 shares
were exercisable.

The weighted average fair value per option granted in 1997, 1996, and 1995 was
$9.72, $5.91, and $4.71, 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 1997, 1996, and 1995,
respectively: risk free interest rates of 6.36%, 5.73%, and 6.88%; volatility of
47.94%, 54.4%, and 65.5%; and expected lives of five years for all 1997, 1996,
and 1995 option grants with payment of no dividends.

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

Because the Statement 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.

POSTRETIREMENT BENEFIT PLANS.  Steel sponsors an unfunded, defined benefit,
postretirement health care plan ("Health Care Plan") for most of its bargaining
unit employees and a limited number of nonbargaining unit retirees eligible
under special early retirement programs.  Health Care Plan benefits are provided
to eligible retirees and their spouses until they reach the age of 65, at which
time coverage terminates.  Additionally, Steel provides for certain other
postretirement benefits, primarily life insurance.  Steel accrues for the
anticipated cost of these postretirement benefits over the employees' years of
service.  Net postretirement benefits expense for 1997, 1996, and 1995 included
the following components:

The annual rate of the increase in per capita cost of covered health care
benefits was assumed to gradually decrease from 8% to an ultimate trend rate of
6% by the year 2004.  An increase of 1% per year in the assumed medical cost
trend rate would have resulted in an additional obligation of $1.2 million for
accumulated benefits at December 31, 1997, and an additional $0.2 million in the
aggregate of the service cost and interest cost components of net benefits
expense for 1997.  A weighted average discount rate of 7% and 7.5% was used to
determine the accumulated obligation at December 31, 1997 and 1996,
respectively.

PENSION PLANS.  Steel has three defined benefit pension plans covering
substantially all of its bargaining unit employees.  Retirement benefits are
based on years of service at progressively increasing flat-rate amounts.  A
special lump-sum payment equal to 13 weeks of vacation pay is made upon
retirement.  Steel's policy is to fund the minimum contribution each year as
required by applicable regulations.

During 1996, the largest of Steel's three plans was amended so that new
employees hired on or after June 4, 1996, do not participate in the defined
benefit plan.  Such new employees are eligible to participate in one of Steel's
defined contribution retirement plans, as are substantially all other employees.
The amendment also provided for increased benefits to plan participants retiring
on or after June 1, 1996.

In determining the projected benefit obligation, weighted average discount rates
of 7% and 7.5% were used for 1997 and 1996, respectively.  The expected
long-term rate of return on assets was assumed to be 9% for both years.  The
annual rate of increase in compensation was assumed to be 4% for both 1997 and
1996.  Steel has recorded an adjustment, as shown in the above table, to
recognize a minimum pension liability.  Offsetting this liability at December
31, 1997, was a noncurrent intangible asset of $4.4 million and a reduction of
shareholders' equity of $9.7 million, with no recorded tax benefit assumed.  The
December 31, 1996 balance sheet reflected an offsetting $5.6 million intangible
asset and a reduction of shareholders' equity of $6.8 million, net of minority
interest.  The plans' assets consist primarily of short-term money market
investments, government and corporate obligations, real estate, and public
market equity securities.

Net pension expense in 1997, 1996, and 1995 was as follows:

PROFIT SHARING PLAN.  Steel has a profit sharing plan for substantially all
employees which provides for payment of a specified percentage of Steel's
quarterly operating earnings.  Steel's payments to employees were $3.9 million,
$2.7 million, and $0.6 million for 1997, 1996, and 1995, respectively.

COMMITMENTS AND CONTINGENCIES - NOTE I

Steel has various commitments for the purchase of raw materials, 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 C 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
$3.9 million, $3.7 million, and $3.5 million in 1997, 1996, and 1995,
respectively.  Future minimum lease payments under noncancellable operating
leases are as follows:  1998, $1.7 million; 1999, $1.6 million; 2000, $1.1
million; 2001, $0.6 million; and 2002, $0.4 million, and thereafter,
$0.9 million.

LST and its subsidiaries are parties to a number of lawsuits and controversies
which are not discussed herein.  Management of LST 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 LST and
its subsidiaries, taken as a whole.


GAIN FROM DISCONTINUED OPERATIONS AND EXTRAORDINARY ITEMS - NOTE J

In November 1993, LST sold the stock of AFB, one of its operating subsidiaries.
The sale price was $155.7 million; of that, LST 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.

Extraordinary items recognized in 1997 include a gain of $2.0 million related to
reduction of the UMWA liability (Note C), reduced by a loss of $1.1 million for
the early prepayment fee in connection with the refinancing of Steel's revolving
credit facility (Note E).  There were no income tax effects recognized for these
items.

                                        POLICY


     In order to attract and retain officers and key employees for Lone Star
Technologies, Inc. (the "Corporation") and its subsidiaries, particularly in the
event of a threat or the occurrence of a Change in Control, the Board of
Directors of the Corporation (the "Board") has adopted the following Employment
Retention Policy:

     If the employment of any Officer or key employee designated by the Board or
its Compensation Committee (the "Committee") is involuntarily terminated without
Cause or is voluntarily terminated with Good Reason within two years after the
occurrence of a Change in Control of his Employer, his Employer shall pay a lump
sum, as determined by the Board or the Committee, to the Officer in an amount
that does not exceed twenty-four times his Monthly Compensation or to the key
employee in an amount that does not exceed twelve times his Monthly
Compensation. Each person designated by the Board or the Committee will be
covered by this Policy upon his entering into the letter agreement in the form
attached.

     The Board shall have the right to amend or terminate this Policy at any
time, but any such amendment or termination, whether adopted prior to or after a
Change in Control, shall not adversely affect any person covered by this Policy
prior to such amendment or termination.

     The Corporation will request that the other Employers adopt this Policy and
will make reasonable efforts to require any successor to the business or assets
of any Employer expressly to assume and to agree to be bound by this Policy.

DEFINITIONS:

     "Cause" for termination of a person's employment means his illegal conduct
or gross misconduct that in either case is willful and results in material
damage to his Employer's business or reputation or his willful failure or
refusal to perform his duties or obligations to his Employer or to comply in all
material respects with the lawful directives of the Employer's Chief Executive
Officer or Board of Directors, provided that he has received written notice from
his Employer stating the nature of such failure or refusal and has reasonable
opportunity to correct the stated deficiency.

     "Change in Control" means, with respect to an Employer that is a subsidiary
of the Corporation, (i) any event that results in the Corporation not
controlling the Employer or owning all or substantially all of the Employer's
assets or (ii) any Change in Control of the Corporation.

<PAGE>

     "Change in Control" means, with respect to the Corporation, any of the
following:

     (i)   any event affecting the Corporation that would be required to be
reported by a reporting company as a change in control pursuant to Regulation
14A under the Securities Exchange Act of 1934, as amended (the "Exchange Act");

     (ii)  any "person" (as that term is used in Section 13(d) of the Exchange
Act) becomes the "beneficial owner" (as defined by Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Corporation representing more
than 50% of either the then outstanding shares of the Corporation's Common Stock
or the combined voting power of the Corporation's then outstanding securities;

     (iii) at any time during any twenty-four month period, the individuals
who were serving on the Board at the beginning of that period or who were
nominated for election or were elected to the Board during that period by a vote
of at least two-thirds of such individuals still in office shall cease to
constitute a majority of the Board;

     (iv)  any merger or consolidation of the Corporation with any other
corporation or any sale of all or substantially all of the assets of the
Corporation, other than a merger, consolidation or sale that results in the
voting securities of the Corporation outstanding immediately prior thereto
continuing to represent more than 50% of the combined voting power of the voting
securities of the Corporation or the surviving entity or any parent thereof
outstanding immediately thereafter; or

     (v)   the stockholders of the Corporation approve a plan of complete
liquidation or dissolution of the Corporation.

     "Employer" is the Corporation or any corporation that is or becomes a
subsidiary of the Corporation and its respective successors and assigns.

     "Good Reason" with respect to the voluntary termination of a person's
employment means the occurrence, after a Change in Control, of (i) any adverse
change in his status, position, authority or responsibilities, (ii) a reduction
in his compensation, (iii) any material change in his employment location or
(iv) the failure or refusal of any successor to his Employer to expressly assume
his Employer's obligations under this Policy.

     "Monthly Compensation" is a person's salary and cash bonus paid during the
twelve months prior to the termination of his employment or, if higher, his
salary and cash bonus paid during the twelve months prior to the Change in
Control of his Employer, in each case computed as a monthly average.

     "Officer" is any person who is or becomes the President, Chief Executive
Officer, Treasurer, Controller, Secretary or any Vice President of an Employer.

     Each Bank shall be obligated to participate in each request for Revolving 
Credit Loans pursuant to Section 2.4 [Revolving Credit Loan Requests] in 
accordance with its Ratable Share. The aggregate of each Bank's Revolving 
Credit Loans outstanding hereunder to the Borrower at any time shall never 
exceed its Revolving Credit Commitment minus its Ratable Share of the Letters 
of Credit Outstanding. The obligations of each Bank hereunder are several. 
The failure of any Bank to perform its obligations hereunder shall not affect 
the Obligations of the Borrower to any other party nor shall any other party 
be liable for the failure of such Bank to 

                                     -21-
<PAGE>

perform its obligations hereunder. The Banks shall have no obligation to make 
Revolving Credit Loans hereunder on or after the Expiration Date.

     2.3  COMMITMENT FEES.

     Accruing from the date hereof to the Expiration Date, the Borrower agrees
to pay to the Agent for the account of each Bank, as consideration for such
Bank's Revolving Credit Commitment hereunder, a nonrefundable commitment fee
(the "Commitment Fee") equal to the Applicable Commitment Fee Rate (computed on
the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed) on the average daily difference between the amount of (i) such Bank's
Revolving Credit Commitment as the same may be constituted from time to time and
the (ii) the sum of such Bank's Loans outstanding plus its Ratable Share of the
amount of Letters of Credit Outstanding. All Commitment Fees shall be payable in
arrears on the first Business Day of each October, January, April and July after
the date hereof and on the Expiration Date or upon acceleration of the Notes.

time to time prior to the Expiration Date request the Banks to make Revolving

existing Revolving Credit Loans pursuant to Section 4.2 [Interest Periods], by
delivering to the Agent, not later than 12:00 Noon, Pittsburgh time, (i) three

making of Revolving Credit Loans to which the Euro-Rate Option applies or the
conversion to or the renewal of the Euro-Rate Option for any Loans; and (ii) one

last day of the preceding Interest Period with respect to the conversion to the
Base Rate Option for any Loan, of a duly completed request therefor
substantially in the form of EXHIBIT 2.4.1 or a request by telephone immediately
confirmed in writing by letter, facsimile or telex in such form (each, a "Loan
Request"), it being understood that the Agent may rely on the authority of any
individual making such a telephonic request without the necessity of receipt of
such written confirmation. Each Loan Request shall be irrevocable and shall
specify (i) the proposed Borrowing Date; (ii) the aggregate amount of the
proposed Loans comprising each Borrowing Tranche, which shall be in integral
multiples of $500,000 and not less than $1,000,000 for each Borrowing Tranche to
which the Euro-Rate Option applies and not less than the lesser of $500,000 or
the maximum amount available for Borrowing Tranches to which the Base Rate
Option applies; (iii) whether the Euro-Rate Option or Base Rate Option shall
apply to the proposed Loans comprising the applicable Borrowing Tranche; and
(iv) in the case of a Borrowing Tranche to which the Euro-Rate Option applies,

Borrowing Date of a duly completed request therefor substantially in the form of

confirmation. Each Swing Loan Request shall be irrevocable and shall specify the
proposed Borrowing Date and the principal amount of such Swing Loan, which shall
be not less than $100,000.

AND SWING NOTES.

               2.5.1     MAKING REVOLVING CREDIT LOANS.

     The Agent shall, promptly after receipt by it of a Loan Request pursuant to
Section 2.4 [Revolving Credit Loan Requests], notify the Banks of its receipt of
such Loan Request specifying: (i) the proposed Borrowing Date and the time and
method of disbursement of the Revolving Credit Loans requested thereby; (ii) the
amount and type of each such Revolving Credit Loan and the applicable Interest
Period (if any); and (iii) the apportionment among the Banks of such Revolving
Credit Loans as determined by the Agent in accordance with Section 2.2 [Nature
of Banks' Obligations]. Each Bank shall remit the principal amount of each
Revolving Credit Loan to the Agent such that the Agent is able to, and the Agent
shall, to the extent the Banks have made funds available to it for such purpose
and subject to Section 7.2 [Each Additional Loan], find such Revolving Credit
Loans to the Borrower in U.S. Dollars and immediately available funds at the
Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable
Borrowing Date, PROVIDED that if any Bank fails to remit such funds to the Agent
in a timely manner, the Agent may elect in its sole discretion to fund with its
own funds the Revolving Credit Loans of such Bank on such Borrowing Date, and
such Bank shall be subject to the repayment obligation in Section 10.16
[Availability of Funds].

               2.5.2     MAKING SWING LOANS.

                    So long as PNC Bank elects to make Swing Loans, PNC Bank
shall, after receipt by it of a Swing Loan Request pursuant to Section 2.4.2,
fund such Swing Loan to the Borrower in U.S. Dollars and immediately available
funds at the Principal Office prior to 3:00 o'clock PM Pittsburgh time on the
Borrowing Date. PNC Bank may at any time (i) terminate, temporarily or
permanently, the Swing Loan facility hereunder by notifying the Borrower or (ii)
elect not to make a Swing Loan following its receipt of a Swing Loan Request
(and before the making of such Swing Loan).


                                     -23-

     2.6  REVOLVING CREDIT NOTES.

     The Obligation of the Borrower to repay the aggregate unpaid principal
amount of the Revolving Credit Loans made to it by each Bank, together with
interest thereon, shall be evidenced by a Revolving Credit Note dated the
Closing Date payable to the order of such Bank in a face amount equal to the
Revolving Credit Commitment of such Bank.

     2.7  SWING LOAN NOTE.

     The Obligation of the Borrower to repay the aggregate unpaid principal
amount of the Swing Loans made to it by PNC Bank, together with interest
thereon, shall be evidenced by the Swing Loan Note dated the Closing Date
payable to the order of PNC Bank in a face amount equal to the Swing Loan
Commitment.

     2.8  USE OF PROCEEDS.

     The proceeds of the Revolving Credit Loans shall be used to refinance the
Indebtedness of the Borrower for borrowed money existing prior to the Closing
Date, to redeem the Preferred Stock of the Borrower and to make certain
dividends and other distributions to Lone Star Technologies permitted hereunder
and for general purposes all in accordance with Section 8.1.10 [Use of
Proceeds].

     2.9  BORROWINGS TO REPAY SWING LOANS.

     PNC may, at its option, exercisable at any time for any reason whatsoever,
demand repayment of the Swing Loans, and each Bank shall make a Revolving Credit
Loan in an amount equal to such Bank's Ratable Share of the aggregate principal
amount of the outstanding Swing Loans, plus, if PNC so requests, accrued
interest thereon, PROVIDED that no Bank shall be obligated in any event to make
Revolving Credit Loans in excess of its Revolving Credit Commitment. Revolving
Credit Loans made pursuant to the preceding sentence shall bear interest at the
Base Rate Option and shall be deemed to have been properly requested in
accordance with Section 2.4.1 and of the apportionment among the Banks, and the
Banks shall be unconditionally obligated to fund such Revolving Credit Loans
(whether or not the conditions specified in Section 2.4.1 are then satisfied) by
the time PNC so requests, which shall not be earlier than 3:00 p.m. Pittsburgh

     2.10 LETTER OF CREDIT SUBFACILITY.

               2.10.1   ISSUANCE OF LETTERS OF CREDIT.

                    Borrower may request the issuance of a letter of credit
(each a "Letter of Credit") on behalf of itself or another Loan Party by
delivering to the Agent a completed application and agreement for letters of
credit in such form as the Agent may specify from time to time by no later than
Noon Pittsburgh time, at least five (5) Business Days, or such shorter period as
may be agreed to by the Agent, in advance of the proposed date of issuance. 


                                     -24-

<PAGE>

Each Letter of Credit shall be either a Standby Letter of Credit or a 
Commercial Letter of Credit. Subject to the terms and conditions hereof and 
in reliance on the agreements of the other Banks set forth in this Section 
2.10, the Agent will issue a Letter of Credit provided that each Letter of 
Credit shall (A) have a maximum maturity of twenty four (24) months from the 
date of issuance, and (B) in no event expire later than ten (10) Business 
Days prior to the Expiration Date and providing that in no event shall (i) 
the Letters of Credit Outstanding exceed, at any one time, $20,000,000 or 
(ii) the Revolving Facility Usage exceed, at any one time, the Revolving 
Credit Commitments (for purposes of this computation, PNC Bank's Swing Loans 
shall be deemed to be borrowed amounts under its Revolving Credit Commitment).

               2.10.2    LETTER OF CREDIT FEES.

                    The Borrower shall pay (i) to the Agent for the ratable
account of the Banks a fee (the "Letter of Credit Fee") at a percentage rate per
annum equal to the Applicable Margin which applies to Loans under the Euro-Rate
Option, and (ii) to the Agent for its own account a fronting fee equal to 1/8%
per annum (computed on the basis of a year of 360 days and actual days elapsed),
which fees shall be computed on the daily average Letters of Credit Outstanding
and shall be payable quarterly in arrears commencing with the first Business Day
of each October, January, April and July following issuance of each Letter of
Credit and on the Expiration Date. The Borrower shall also pay to the Agent for
the Agent's sole account the Agent's then in effect customary administrative
fees and expenses payable with respect to the Letters of Credit as the Agent may
generally charge or incur from time to time in connection with the issuance,
maintenance, modification (if any), assignment or transfer (if any),
negotiation, and administration of Letters of Credit.

               2.10.3    DISBURSEMENTS, REIMBURSEMENT.

                         2.10.3.1  Immediately upon the Issuance of each Letter
of Credit, each Bank shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Agent a participation in such
Letter of Credit and each drawing thereunder in an amount equal to such Bank's
Ratable Share of the maximum amount available to be drawn under such Letter of
Credit and the amount of such drawing, respectively. Each Bank is hereby deemed
to, and hereby irrevocably and unconditionally agrees to, purchase from the
Agent a participation in the Overdraft Reimbursement Agreement and each of the
Agent's obligations thereunder, including the Agent's obligations in connection
with any right of CITBC to be reimbursed by the Agent, in an amount equal to
such Bank's Ratable Share of each such obligation.

                         2.10.3.2  In the event of any request for a drawing
under a Letter of Credit by the beneficiary or transferee thereof or any demand
for reimbursement by or right of reimbursement in favor of CITBC under the
Overdraft Reimbursement Agreement, the Agent will promptly notify the Borrower.
Provided that it shall have received such notice, the Borrower shall reimburse
(such obligation to reimburse the Agent shall sometimes be referred to as a
"Reimbursement Obligation") the Agent prior to 12:00 noon, Pittsburgh time on
each date that an amount is paid by the Agent under any Letter of Credit or
Overdraft Reimbursement 


                                     -25-

<PAGE>

Agreement (each such date, a "Drawing Date") in an amount equal to the amount 
so paid by the Agent. In the event the Borrower fails to reimburse the Agent 
for the full amount of any drawing under any Letter of Credit or payment by 
the Agent under the Overdraft Reimbursement Agreement by 12:00 noon, 
Pittsburgh time, on the Drawing Date, the Agent will promptly notify each 
Bank thereof, and the Borrower shall be deemed to have requested that 
Revolving Credit Loans be made by the Banks under the Base Rate Option to be 
disbursed on the Drawing Date under such Letter of Credit or Overdraft 
Reimbursement Agreement, subject to the amount of the unutilized portion of 
the Revolving Credit Commitment and subject to there being no Potential 
Default or Event of Default described in or arising under Sections 9.1.14 
or 9.1.15 (each a "Bankruptcy Default"). Any notice given by the Agent 
pursuant to this Section 2.10.3.2 may be oral if immediately confirmed in 
writing; provided that the lack of such an immediate confirmation shall not 
affect the conclusiveness or binding effect of such notice.

                         2.10.3.3 Each Bank shall upon any notice pursuant to 
Section 2.10.3.2 make available to the Agent an amount in immediately 
available funds equal to its Ratable Share of the amount of the drawing or 
other payment by the Agent, whereupon the participating Banks shall (subject 
to Section 2.10.3.4) each be deemed to have made a Revolving Credit Loan 
under the Base Rate Option to the Borrower in that amount. If any Bank so 
notified fails to make available to the Agent for the account of the Agent 
the amount of such Bank's Ratable Share of such amount by no later than 2:00 
p.m., Pittsburgh time on the Drawing Date, then interest shall accrue on such 
Bank's obligation to make such payment, from the Drawing Date to the date on 
which such Bank makes such payment (i) at a rate per annum equal to the 
Federal Funds Effective Rate during the first three days following the 
Drawing Date and (ii) at a rate per annum equal to the rate applicable to 
Loans under the Base Rate Option on and after the fourth day following the 
Drawing Date. The Agent will promptly give notice of the occurrence of the 
Drawing Date, but failure of the Agent to give any such notice on the Drawing 
Date or in sufficient time to enable any Bank to effect such payment on such 
date shall not relieve such Bank from its obligation under this Section 
2.10.3.3.

                         2.10.3.4  With respect to any unreimbursed drawing or
other payment by the Agent described in this Section 2.10.3 above that is not
converted into Revolving Credit Loans under the Base Rate Option to the Borrower
in whole or in part as contemplated by Section 2.10.3.2, because of the
existence of a Bankruptcy Default or for any other reason, the Borrower shall be
deemed to have incurred from the Agent a borrowing (each a "Reimbursement
Borrowing") in the amount of such drawing. Such Reimbursement Borrowing shall be
due and payable on demand (together with interest) and shall bear interest at
the rate per annum applicable to the Revolving Credit Loans under the Base Rate
Option. Each Bank's payment to the Agent pursuant to Section 2.10.3.3 shall be
deemed to be a payment in respect of its participation in such Reimbursement
Borrowing and shall constitute a Participation Advance from such Bank in
satisfaction of its participation obligation under this Section 2.10.3.

               2.10.4   REPAYMENT OF PARTICIPATION ADVANCES.

                         2.10.4.1  Upon (and only upon) receipt by the Agent 
for its account of immediately available funds from the Borrower (i) in 
reimbursement of any 

                                     -26-

<PAGE>

payment made by the Agent under the Letter of Credit or the Overdraft 
Reimbursement Agreement with respect to which any Bank has made a 
Participation Advance to the Agent, or (ii) in payment of interest on such a 
payment made by the Agent under such a Letter of Credit or Overdraft 
Reimbursement Agreement, the Agent will pay to each Bank, in the same funds 
as those received by the Agent, the amount of such Bank's Ratable Share of 
such funds, except the Agent shall retain the amount of the Ratable Share of 
such funds of any Bank that did not make a Participation Advance in respect 
of such payment by Agent.

                         2.10.4.2  If the Agent is required at any time to
return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or
any official in any Insolvency Proceeding, any portion of the payments made by
any Loan Party to the Agent pursuant to Section 2.10.4.1 in reimbursement of a
payment made under the Letter of Credit or the Overdraft Reimbursement Agreement
or interest or fee thereon, each Bank shall, on demand of the Agent, forthwith
return to the Agent the amount of its Ratable Share of any amounts so returned
by the Agent plus interest thereon from the date such demand is made to the date
such amounts are returned by such Bank to the Agent, at a rate per annum equal
to the Federal Funds Effective Rate in effect from time to time.

               2.10.5    DOCUMENTATION.

                    Each Loan Party agrees to be bound by the terms of the 
Overdraft Reimbursement Agreement and the Agent's application and agreement 
for letters of credit. In the event of a conflict between such Overdraft 
Reimbursement Agreement or application for letters of credit or agreement and 
this Agreement, this Agreement shall govern. It is understood and agreed 
that, except in the case of gross negligence or willful misconduct, the Agent 
shall not be liable for any error, negligence and/or mistakes, whether of 
omission or commission, in following any Loan Party's instructions or those 
contained in the Letters of Credit or Overdraft Reimbursement Agreement or 
any modifications, amendments or supplements thereto.

               2.10.6    DETERMINATIONS TO HONOR DRAWING REQUESTS.

                    In determining whether to honor any request for drawing
under any Letter of Credit by the beneficiary thereof, the Agent shall be
responsible only to determine that the documents and certificates required to be
delivered under such Letter of Credit have been delivered and that they on their
face comply with and satisfy the requirements of such Letter of Credit.

               2.10.7    NATURE OF PARTICIPATION AND REIMBURSEMENT OBLIGATIONS.

                    Each Bank's obligation in accordance with this Agreement to
make the Revolving Credit Loans or Participation Advances, as contemplated by
Section 2.10.3, as a result of a drawing under a Letter of Credit, and the
Obligations of the Borrower to reimburse the Agent upon a draw under a Letter of
Credit, shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Section 2.10 under all
circumstances, including the following circumstances:


                                     -27-

<PAGE>

right which such Bank may have against the Agent, the Borrower or any other
Person for any reason whatsoever;

               (ii)   the failure of any Loan Party or any other Person to 
comply, in connection with a Reimbursement Borrowing, with the conditions set 
forth in Section 2.1 [Revolving Credit Commitments], 2.4 [Revolving Credit 
Loan Requests], 2.5.1 [Making Revolving Credit Loans] or 7.2 [Each Additional 
Loan] or as otherwise set forth in this Agreement for the making of a Revolving
Credit Loan, it being acknowledged that such conditions are not required for 
the making of a Reimbursement Borrowing and the obligation of the Banks to 
make Participation Advances under Section 2.10.3;

               (iii)  any lack of validity or enforceability of any Letter of
Credit;

               (iv)   the existence of any claim, set-off, defense or other 
right which any Loan Party or any Bank may have at any time against a 
beneficiary or any transferee of any Letter of Credit (or any Persons for whom
any such transferee may be acting), the Agent or any Bank or any other Person 
or, whether in connection with this Agreement, the transactions contemplated 
herein or any unrelated transaction (including any underlying transaction 
between any Loan Party or Subsidiaries of a Loan Party and the beneficiary for 
which any Letter of Credit was procured);

               (v)    any draft, demand, certificate or other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect even if the Agent has been notified thereof;

               (vi)   payment by the Agent under any Letter of Credit against
presentation of a demand, draft or certificate or other document which does not
comply with the terms of such Letter of Credit;

               (vii)  any adverse change in the business, operations, 
properties, assets, condition (financial or otherwise) or prospects of any 
Loan Party or Subsidiaries of a Loan Party;

               (viii) any breach of this Agreement or any other Loan Document by
any party thereto;

               (ix)   the occurrence or continuance of an Insolvency Proceeding
with respect to any Loan Party;

               (x)    the fact that an Event of Default or a Potential Default
shall have occurred and be continuing; and


                                     -28-

<PAGE>

               (xi)   the fact that the Expiration Date shall have passed or 
this Agreement or the Commitments hereunder shall have been terminated.

               2.10.8    INDEMNITY.

                    In addition to amounts payable as provided in Section 10.5
[Reimbursement and Indemnification of Agent by the Borrower], the Borrower
hereby agrees to protect, indemnify, pay and save harmless the Agent from and
against any and all claims, demands, liabilities, damages, losses, costs,
charges and expenses (including reasonable fees, expenses and disbursements of
counsel and allocated costs of internal counsel) which the Agent may incur or be
subject to as a consequence, direct or indirect, of (i) the issuance of any
Letter of Credit, other than as a result of (A) the gross negligence or willful
misconduct of the Agent as determined by a final judgment of a court of
competent jurisdiction or (B) subject to the following clause (ii), the wrongful
dishonor by the Agent of a proper demand for payment made under any Letter of
Credit, or (ii) the failure of the Agent to honor a drawing under any such
Letter of Credit as a result of any act or omission, whether rightful or
wrongful, of any present or future de jure or de facto Official Body (all such
acts or omissions herein called "Governmental Acts").

               2.10.9    LIABILITY FOR ACTS AND OMISSIONS.

                    As between any Loan Party and the Agent, such Loan Party 
assumes all risks of the acts and omissions of, or misuse of the Letters of 
Credit by, the respective beneficiaries of such Letters of Credit. In 
furtherance and not in limitation of the foregoing, the Agent shall not be 
responsible for: (i) the form, validity, sufficiency, accuracy, genuineness 
or legal effect of any document submitted by any party in connection with the 
application for an issuance of any such Letter of Credit, even if it should 
in fact prove to be in any or all respects invalid, insufficient, inaccurate, 
fraudulent or forged (even if the Agent shall have been notified thereof); 
(ii) the validity or sufficiency of any instrument transferring or assigning 
or purporting to transfer or assign any such Letter of Credit or the rights 
or benefits thereunder or proceeds thereof, in whole or in part, which may 
prove to be invalid or ineffective for any reason; (iii) the failure of the 
beneficiary of any such Letter of Credit, or any other party to which such 
Letter of Credit may be transferred, to comply fully with any conditions 
required in order to have a right to draw upon such Letter of Credit or any 
other claim of any Loan Party against any beneficiary of such Letter of 
Credit, or any such transferee, or any dispute between or among any Loan 
Party and any beneficiary of any Letter of Credit or any such transferee; 
(iv) errors, omissions, interruptions or delays in transmission or delivery 
of any messages, by mail, cable, telegraph, telex or otherwise, whether or 
not they be in cipher; (v) errors in interpretation of technical terms; (vi) 
any loss or delay in the transmission or otherwise of any document required 
in order to make a drawing under any such Letter of Credit or of the proceeds 
thereof; (vii) the misapplication by the beneficiary of any such Letter of 
Credit of the proceeds of any drawing under such Letter of Credit; or (viii) 
any consequences arising from causes beyond the control of the Agent, 
including any Governmental Acts, and none of the above shall affect or 
impair, or prevent the vesting of, any of the Agent's rights or powers 
hereunder. Nothing in the preceding sentence shall relieve the Agent from 
liability for the Agent's gross negligence or 

                                     -29-

<PAGE>

willful misconduct in connection with actions or omissions described in such 
clauses (i) through (viii) of such sentence.

                         In furtherance and extension and not in limitation of
the specific provisions set forth above, any action taken or omitted by the
Agent under or in connection with the Letters of Credit issued by it or any
documents and certificates delivered thereunder, if taken or omitted in good
faith, shall not put the Agent under any resulting liability to the Borrower or
any Bank.

                    2.10.10   COMPARABLE TREATMENT OF THE AGENT UNDER OVERDRAFT
REIMBURSEMENT AGREEMENT AND LETTERS OF CREDIT.

                         All of the rights given to the Agent under Sections
2.10.6 through 2.10.9 above relating to Letters of Credit issued by the Agent
hereunder shall apply in a comparable manner and shall be given to the Agent
relating to the Overdraft Reimbursement Agreement and each reference in such
Section to a Letter of Credit or Letters of Credit shall be deemed to refer also
to the Overdraft Reimbursement Agreement.

          2.11 EXTENSION BY BANKS OF THE EXPIRATION DATE.

          Upon or promptly after delivery by the Borrower of the annual
financial statements to be provided under Section 8.3.2 [Annual Financial
Statements] for the fiscal year ending December 31, 1998 or any subsequent
fiscal year, the Borrower may request a one-year extension of the Expiration
Date by written notice to the Banks, and the Banks agree to respond to the
Borrower's request for an extension by the later of sixty (60) days following
receipt of the request or May 31 of such year; provided, however, that the
failure of any Bank to respond within such time period shall not in any manner
constitute an agreement by such Bank to extend the Expiration Date. If all Banks
elect to extend, the Expiration Date shall be extended for a period of one year.

                                   3.  COLLATERAL

     Each of the Loan Parties shall grant first priority Liens in their assets
(including capital stock of each of the Loan Parties but excluding all real
property, all stock of the Inactive Subsidiaries, and any immaterial assets of

Security Agreement, the Security Agreement and the Pledge Agreement. Any

Obligations of the Loan Parties hereunder pursuant to a Guaranty Agreement as
more fully provided in Sections 8.2.9 and 11.18. Each of the Loan Parties and
Lone Star Technologies shall execute and deliver to the Agent for the benefit of
the Banks the Intercompany Subordination Agreement as provided in Section 7.1.3.

                                  4.  INTEREST RATES

          4.1  INTEREST RATE OPTIONS.

          The Borrower shall pay interest in respect of the outstanding unpaid
principal amount of the Loans as selected by it from the Base Rate Option or
Euro-Rate Option set forth below applicable to the Loans, it being understood
that, subject to the provisions of this Agreement, the Borrower may select
different Interest Rate Options and different Interest Periods to apply
simultaneously to the Loans comprising different Borrowing Tranches and may
convert to or renew one or more Interest Rate Options with respect to all or any
portion of the Loans comprising any Borrowing Tranche, PROVIDED that there shall
not be at any one time outstanding more than Six (6) Borrowing Tranches in the
aggregate among all of the Loans, and PROVIDED FURTHER that only the Base Rate
Option shall apply to the Swing Loans. If at any time the designated rate
applicable to any Loan made by any Bank exceeds such Bank's highest lawful rate
(i.e., the highest rate such Bank is permitted to charge to the Borrower, taking
into account all applicable Laws), the rate of interest on such Bank's Loan
shall be limited to such Bank's highest lawful rate.

                    4.1.1     RATE OPTIONS.

                         The Borrower shall have the right to select from the
following Interest Rate Options applicable to the Revolving Credit Loans
(subject to the provisions above regarding Swing Loans):

                              (i)  REVOLVING CREDIT BASE RATE OPTION: A
fluctuating rate per annum (computed on the basis of a year of 365 or 366 days,
as the case may be, and actual days elapsed) equal to the Base Rate plus the
Applicable Margin, such interest rate to change automatically from time to time
effective as of the effective date of each change in the Base Rate; or

                              (ii) REVOLVING CREDIT EURO-RATE OPTION: A rate per
annum (computed on the basis of a year of 360 days and actual days elapsed)
equal to the Euro-Rate plus the Applicable Margin.

                    4.1.2     RATE QUOTATIONS.

                         The Borrower may call the Agent on or before the date
on which a Loan Request is to be delivered to receive an indication of the rates
then in effect, but it is acknowledged that such projection shall not be binding
on the Agent or the Banks nor affect the rate of interest which thereafter is
actually in effect when the election is made.

          4.2  INTEREST PERIODS.

          At any time when the Borrower shall select, convert to or renew a
Euro-Rate Option, the Borrower shall notify the Agent thereof at least three (3)
Business Days prior to the effective date of such Euro-Rate Option by delivering
a Loan Request. The notice shall specify 


                                     -31-

<PAGE>

an interest period (the "Interest Period") during which such Interest Rate 
Option shall apply, such Interest Period to be one, two, three or six Months 
if Borrower selects the Euro-Rate Option. Notwithstanding the preceding 
sentence, the following provisions shall apply to any selection of, renewal 
of, or conversion to a Euro-Rate Option:

                    4.2.1     ENDING DATE AND BUSINESS DAY.

                         any Interest Period which would otherwise end on a date
which is not a Business Day shall be extended to the next succeeding Business
Day unless such Business Day falls in the next calendar month, in which case
such Interest Period shall end on the next preceding Business Day;

                    4.2.2     AMOUNT OF BORROWING TRANCHE.

                         each Borrowing Tranche of Euro-Rate Loans shall be in
integral multiples of $500,000 and not less than $1,000,000

                    4.2.3     TERMINATION BEFORE EXPIRATION DATE.

                         the Borrower shall not select, convert to or renew an
Interest Period for any portion of the Loans that would end after the Expiration
Date; and

                    4.2.4     RENEWALS.

                         in the case of the renewal of a Euro-Rate Option at the
end of an Interest Period, the first day of the new Interest Period shall be the
last day of the preceding Interest Period, without duplication in payment of
interest for such day.

          4.3  INTEREST AFTER DEFAULT.

          To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time as such Event of Default shall have been cured or
waived:

                    4.3.1     LETTER OF CREDIT FEES. INTEREST RATE.

                         the Letter of Credit Fees and the rate of interest for
each Loan otherwise applicable pursuant to Section 2.10.2 [Letter of Credit
Fees] or Section 4.1 [Interest Rate Options], respectively, shall be increased
by 2.0% per annum; and

                    4.3.2     OTHER OBLIGATIONS.

                         each other Obligation hereunder if not paid when due
shall bear interest at a rate per annum equal to the sum of the rate of interest
applicable under the Base Rate Option plus an additional 2.0% per annum from the
time such Obligation becomes due and payable and until it is paid in full.

                    4.3.3     ACKNOWLEDGMENT.

                         The Borrower acknowledges that the increase in rates
referred to in this Section 4.3 reflects, among other things, the fact that such
Loans or other amounts have become a substantially greater risk given their
default status and that the Banks are entitled to additional compensation for
such risk; and all such interest shall be payable by Borrower upon demand by
Agent.

          4.4  EURO-RATE UNASCERTAINABLE; ILLEGALITY; INCREASED COSTS; DEPOSITS
NOT AVAILABLE.

                    4.4.1     UNASCERTAINABLE.

                         If on any date on which a Euro-Rate would otherwise be
determined, the Agent shall have determined that:

                              (i)  adequate and reasonable means do not exist
for ascertaining such Euro-Rate, or

                              (ii) a contingency has occurred which materially
and adversely affects the London interbank eurodollar market relating to the
Euro-Rate, the Agent shall have the rights specified in Section 4.4.3.

                    4.4.2     ILLEGALITY; INCREASED COSTS; DEPOSITS NOT 
                              AVAILABLE.

                         If at any time any Bank shall have determined that:

                              (i)  the making, maintenance or funding of any
Loan to which a Euro-Rate Option applies has been made impracticable or unlawful
by compliance by such Bank in good faith with any Law or any interpretation or
application thereof by any Official Body or with any request or directive of any
such Official Body (whether or not having the force of Law), or

                              (ii) such Euro-Rate Option will not adequately and
fairly reflect the cost to such Bank of the establishment or maintenance of any
such Loan, or

                              (iii) after making all reasonable efforts,
deposits of the relevant amount in Dollars for the relevant Interest Period for
a Loan to which a Euro-Rate Option applies, respectively, are not available to
such Bank with respect to such Loan, in the London interbank market,

then the Agent shall have the rights specified in Section 4.4.3.

                    4.4.3     AGENT'S AND BANK'S RIGHTS.

                         In the case of any event specified in Section 4.4.1
above, the Agent shall promptly so notify the Banks and the Borrower thereof, 
and in the case of an event specified in Section 4.4.2 above, such Bank shall
promptly so notify the Agent and endorse a certificate to such notice as to the
specific circumstances of such notice, and the Agent shall promptly send copies
of such notice and certificate to the other Banks and the Borrower. Upon such
date as shall be specified in such notice (which shall not be earlier than the
date such notice is given), the obligation of (A) the Banks, in the case of such
notice given by the Agent, or (B) such Bank, in the case of such notice given by
such Bank, to allow the Borrower to select, convert to or renew a Euro-Rate
Option shall be suspended until the Agent shall have later notified the
Borrower, or such Bank shall have later notified the Agent, of the Agent's or
such Bank's, as the case may be, determination that the circumstances giving
rise to such previous determination no longer exist. If at any time the Agent
makes a determination under Section 4.4.1 and the Borrower has previously
notified the Agent of its selection of conversion to or renewal of a Euro-Rate
Option and such Interest Rate Option has not yet gone into effect, such
notification shall be deemed to provide for selection of, conversion to or
renewal of the Base Rate Option otherwise available with respect to such Loans.
If any Bank notifies the Agent of a determination under Section 4.4.2, the
Borrower shall, subject to the Borrower's indemnification Obligations under
Section 5.5.2 [Indemnity], as to any Loan of the Bank to which a Euro-Rate
Option applies, on the date specified in such notice either convert such Loan to
the Base Rate Option otherwise available with respect to such Loan, or prepay
such Loan in accordance with Section 5.4 [Voluntary Prepayments]. Absent due
notice from the Borrower of conversion or prepayment, such Loan shall
automatically be converted to the Base Rate Option otherwise available with
respect to such Loan upon such specified date.

          4.5  SELECTION OF INTEREST RATE OPTIONS.

          If the Borrower fails to select a new Interest Period to apply to any
Borrowing Tranche of Loans under the Euro-Rate Option at the expiration of an
existing Interest Period applicable to such Borrowing Tranche in accordance with
the provisions of Section 4.2 [Interest Periods], or if any such selection is
ineffective for any reason (including Borrower's inability to meet any of the
conditions described in Section 7.2), then the Borrower shall be deemed to have
converted such Borrowing Tranche to the Base Rate Option, as applicable,
commencing upon the last day of the existing Interest Period.

                                    5.  PAYMENTS

          5.1  PAYMENTS.

          All payments and prepayments to be made in respect of principal,
interest, Commitment Fees, Letter of Credit Fees, Agent's Fee or other fees or
amounts due from the Borrower or any other Loan Party hereunder or under the
other Loan Documents shall be payable prior to 12:00 Noon, Pittsburgh time, on
the date when due without presentment, demand, protest 


                                     -34-

<PAGE>

or notice of any kind, all of which are hereby expressly waived by the 
Borrower and each other Loan Party, and without set-off counterclaim or other 
deduction of any nature, and an action therefor shall immediately accrue. 
Such payments shall be made to the Agent at the Principal Office for the 
account of PNC Bank with respect to the Swing Loans and for the ratable 
accounts of the Banks with respect to the Revolving Credit Loans or 
Reimbursement Obligations in U.S. Dollars and in immediately available funds, 
and the Agent shall promptly distribute such amounts to the Banks in 
immediately available funds, PROVIDED that in the event payments are received 
by 11:00 a.m., Pittsburgh time, by the Agent with respect to the Loans and 
such payments are not distributed to the Banks on the same day received by 
the Agent, the Agent shall pay the Banks the Federal Funds Effective Rate 
with respect to the amount of such payments for each day held by the Agent 
and not distributed to the Banks. The Agent's and each Bank's statement of 
account, ledger or other relevant record shall be prima facia evidence of the 
amount of principal of and interest on the Loans and other amounts owing 
under this Agreement.

          5.2  PRO RATA TREATMENT OF BANKS.

          Each borrowing shall be allocated to each Bank according to its
Ratable Share, and each selection of, conversion to or renewal of any Interest
Rate Option and each payment or prepayment by the Borrower with respect to
principal, interest, Commitment Fees, Letter of Credit Fees, or other fees
(except for the Agent's Fee) or amounts due from the Borrower hereunder to the
Banks with respect to the Loans, shall (except as provided in Section 4.4.3
[Agent's and Bank's Rights] in the case of an event specified in Section 4.4
[Euro-Rate Unascertainable, Etc.], 5.4.2 [Replacement of a Bank] or 5.5
[Additional Compensation in Certain Circumstances]) be made in proportion to the
applicable Loans outstanding from each Bank and, if no such Loans are then
outstanding, in proportion to the Ratable Share of each Bank. Notwithstanding
any of the foregoing, each borrowing or payment or prepayment by the Borrower of
principal, interest, fees or other amounts from the Borrower with respect to
Swing Loans shall be made by or to PNC Bank according to Section 2.

          5.3  INTEREST PAYMENT DATES.

          Interest on Loans to which the Base Rate Option applies shall be due
and payable in arrears on the first Business Day of each October, January, April
and July after the date hereof and on the Expiration Date or upon acceleration
of the Notes. Interest on Loans to which the Euro-Rate Option applies shall be
due and payable on the last day of each Interest Period for those Loans and, if
such Interest Period is longer than three (3) Months, also on the 90th day of
such Interest Period. Interest on the principal amount of each Loan or other
monetary Obligation shall be due and payable on demand after such principal
amount or other monetary Obligation becomes due and payable (whether on the
stated maturity date, upon acceleration or otherwise).

          5.4 VOLUNTARY PREPAYMENTS.

                    5.4.1     RIGHT TO PREPAY.

                         The Borrower shall have the right at its option from
time to time to prepay the Loans in whole or part without premium or penalty
(except as provided in Section 5.4.2 below or in Section 5.5 [Additional
Compensation in Certain Circumstances]):

                              (i)  at any time with respect to any Loan to which
the Base Rate Option applies,

                              (ii) on the last day of the applicable Interest
Period with respect to Loans to which a Euro-Rate Option applies,

                              (iii) on the date specified in a notice by any
Bank pursuant to Section 4.4 [Euro-Rate Unascertainable, Etc.] with respect to
any Loan to which a Euro-Rate Option applies.

                         Whenever the Borrower desires to prepay any part of the
Loans, it shall provide a prepayment notice to the Agent by 1:00 p.m. at least
one (1) Business Day prior to the date of prepayment of the Revolving Credit
Loans or no later than Noon, Pittsburgh time, on the date of prepayment of Swing
Loans, setting forth the following information:

               (x)  the date, which shall be a Business Day, on which the
          proposed prepayment is to be made;

               (y)  a statement indicating the application of the prepayment
          between the Swing Loans and Revolving Credit Loans; and

               (z)  the total principal amount of such prepayment, which shall
          not be less than $100,000 for any Swing Loan, $100,000 for any
          Revolving Credit Loan to which the Base Rate Option applies or
          $500,000 for any Revolving Credit Loan to which the Euro-Rate Option
          applies.

               All prepayment notices shall be irrevocable. The principal amount
of the Loans for which a prepayment notice is given, together with interest on
such principal amount except with respect to Loans to which the Base Rate Option
applies, shall be due and payable on the date specified in such prepayment
notice as the date on which the proposed prepayment is to be made. Except as
provided in Section 4.4.3 [Agent's and Bank's Rights], if the Borrower prepays a
Loan but fails to specify the applicable Borrowing Tranche which the Borrower is
prepaying, the prepayment shall be applied first to Loans to which the Base Rate
Option applies, then to Dollar Loans to which the Euro-Rate Option applies. Any
prepayment hereunder shall be subject to the Borrower's Obligation to indemnify
the Banks under Section 5.5.2 [Indemnity].

               5.4.2 REPLACEMENT OF A BANK.

                         In the event any Bank (i) gives notice under Section
4.4 [Euro-Rate Unascertainable, Etc.] or Section 5.5.1 [Increased Costs, Etc.],
(ii) does not fund Revolving Credit Loans because the making of such Loans would
contravene any Law applicable to such Bank, (iii) does not approve any action as
to which consent of the Required Banks is requested by the Borrower and obtained
hereunder, or (iv) becomes subject to the control of an Official Body (other
than normal and customary supervision), then the Borrower shall have the right
at its option, with the consent of the Agent, which shall not be unreasonably
withheld, to prepay the Loans of such Bank in whole, together with all interest
accrued thereon, and terminate such Bank's Commitment within ninety (90) days
after (w) receipt of such Bank's notice under Section 4.4 [Euro-Rate
Unascertainable, Etc.] or Section 5.5.1 [Increased Costs, Etc.], (x) the date
such Bank has failed to fund Revolving Credit Loans because the making of such
Loans would contravene Law applicable to such Bank, (y) the date of obtaining
the consent which such Bank has not approved, or (z) the date such Bank became
subject to the control of an Official Body, as applicable; PROVIDED that the
Borrower shall also pay to such Bank at the time of such prepayment any amounts
required under Section 5.5 [Additional Compensation in Certain Circumstances]
and any accrued interest due on such amount and any related fees; PROVIDED,
however, that the Commitment of such Bank shall be provided by one or more of
the remaining Banks or a replacement bank acceptable to the Agent; PROVIDED,
further, the remaining Banks shall have no obligation hereunder to increase
their Commitments. Notwithstanding the foregoing, the Agent may only be replaced
subject to the requirements of Section 10. 14 [Successor Agent] and PROVIDED
that all Letters of Credit have expired or been terminated or replaced.

                    5.4.3     CHANGE OF LENDING OFFICE.

                         Each Bank agrees that upon the occurrence of any event
giving rise to increased costs or other special payments under Section 4.4.2
[Illegality, Etc.] or Section 5.5.1 [Increased Costs, Etc.] with respect to such
Bank, it will if requested by the Borrower, use reasonable efforts (subject to
overall policy considerations of such Bank) to designate another lending office
for any Loans or Letters of Credit affected by such event, PROVIDED that such
designation is made on such terms that such Bank and its lending office suffer
no economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of such Section. Nothing
in this Section 5.4.3 shall affect or postpone any of the Obligations of the
Borrower or any other Loan Party or the rights of the Agent or any Bank provided
in this Agreement.

          5.5  ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES.

                    5.5.1     INCREASED COSTS OR REDUCED RETURN RESULTING FROM
TAXES, RESERVES, CAPITAL ADEQUACY REQUIREMENTS, EXPENSES, ETC.

                         If any Law, guideline or interpretation or any change
in any Law, guideline or interpretation or application thereof by any Official
Body charged with the 


                                     -37-

<PAGE>

interpretation or administration thereof or compliance with any request or 
directive (whether or not having the force of Law) of any central bank or 
other Official Body:

                              (i)  subjects any Bank to any tax or changes the
basis of taxation with respect to this Agreement, the Notes, the Loans or
payments by the Borrower of principal, interest, Commitment Fees, or other
amounts due from the Borrower hereunder or under the Notes (except for taxes on
the overall net income of such Bank([including taxes referred to in the last
sentence of Section 11.17])),

                              (ii) imposes, modifies or deems applicable any
reserve, special deposit or similar requirement against credits or commitments
to extend credit extended by, or assets (funded or contingent) of, deposits with
or for the account of, or other acquisitions of funds by, any Bank, or

                              (iii) imposes, modifies or deems applicable any
capital adequacy or similar requirement (A) against assets (funded or
contingent) of, or letters of credit, other credits or commitments to extend
credit extended by, any Bank, or (B) otherwise applicable to the obligations of
any Bank under this Agreement, and the result of any of the foregoing is to
increase the cost to, reduce the income receivable by, or impose any additional
expense (including loss of margin) upon any Bank with respect to this Agreement,
the Notes or the making, maintenance or funding of any part of the Loans (or, in
the case of any capital adequacy or similar requirement, to have the effect of
reducing the rate of return on any Bank's capital, taking into consideration
such Bank's customary policies with respect to capital adequacy) by an amount
which such Bank in its sole discretion deems to be material, such Bank shall
from time to time notify the Borrower and the Agent of the amount determined
reasonably and in good faith (using any reasonable averaging and attribution
methods employed in good faith) by such Bank to be necessary to compensate such
Bank for such increase in cost, reduction of income, additional expense or
reduced rate of return. Such notice shall set forth in reasonable detail the
basis for such determination. Such amount shall be due and payable by the
Borrower to such Bank ten (10) Business Days after such notice is given.

                    5.5.2     INDEMNITY.

                         In addition to the compensation required by Section
5.5.1 [Increased Costs, Etc.], the Borrower shall indemnify each Bank against
all liabilities, losses or expenses (including loss of margin, any loss or
expense incurred in liquidating or employing deposits from third parties and any
loss or expense incurred in connection with funds acquired by a Bank to fund or
maintain Loans subject to a Euro-Rate Option) which such Bank sustains or incurs
as a consequence of any

                              (i)  payment, prepayment, conversion or renewal of
any Loan to which a Euro-Rate Option applies on a day other than the last day of
the corresponding Interest Period (whether or not such payment or prepayment is
mandatory, voluntary or automatic and whether or not such payment or prepayment
is then due),


                                     -38-

<PAGE>

                              (ii) attempt by the Borrower to revoke (expressly,
by later inconsistent notices or otherwise) in whole or part any Loan Requests
under Section 2.4 [Revolving Credit Loan Requests] or Section 4.2 [Interest
Periods] or notice relating to prepayments under Section 5.4 [Voluntary
Prepayments], or

                              (iii) default by the Borrower in the performance
or observance of any covenant or condition contained in this Agreement or any
other Loan Document, including any failure of the Borrower to pay when due (by
acceleration or otherwise) any principal, interest, Commitment Fee or any other
amount due hereunder.

                         If any Bank sustains or incurs any such loss or
expense, it shall from time to time notify the Borrower of the amount determined
reasonably and in good faith by such Bank (which determination may include any
reasonably assumptions, allocations of costs and expenses and averaging or
attribution methods as such Bank shall elect) to be necessary to indemnify such
Bank for such loss or expense. Such notice shall set forth in reasonable detail
the basis for such determination. Such amount shall be due and payable by the
Borrower to such Bank ten (10) Business Days after such notice is given.

          5.6  SETTLEMENT DATE PROCEDURES.

          In order to minimize the transfer of funds between the Banks and the
Agent, the Borrower may borrow, repay and reborrow Swing Loans and PNC Bank may
make Swing Loans as provided in Section 2.1.2 hereof. Not later than 10:00 am,
Pittsburgh time, on each Settlement Date, the Agent shall notify each Bank of
its Ratable Share of the total of the Revolving Credit Loans and the Swing Loans
(each a "Required Share"). The Agent shall also effect settlement of the Swing
Loans in accordance with the foregoing sentence on the proposed Borrowing Dates
for Revolving Credit Loans and on any mandatory prepayment dates and may at its
option effect settlement on any other Business Day (each a" Settlement Date").
On each Settlement Date, (i) the Borrower may in its discretion repay all
outstanding Swing Loans, or (ii) if the Borrower does not repay all outstanding
Swing Loans the Agent shall notify each Bank of its Ratable Share of the Swing
Loans (each a "Required Share"). On such Settlement Date, the Borrower shall be
deemed to borrow from the Banks Revolving Credit Loans under the Base Rate
Option equal to the outstanding Swing Loans and simultaneously making payment of
the proceeds thereof in repayment of the Swing Loans. Prior to 12:00 Noon,
Pittsburgh time on such Settlement Date, each Bank shall fund its Required Share
of the Revolving Credit Loans referred to in the preceding sentence by making

covenants:

               Each Loan Party shall, and shall cause each of its 
Subsidiaries to, maintain its legal existence as a corporation, limited 
partnership or limited liability company and its license or qualification and

[Liquidations, Mergers, Etc.].

          8.1.2     PAYMENT OF LIABILITIES, INCLUDING TAXES, ETC.

               Each Loan Party shall, and shall cause each of its

subject or which are asserted against it, promptly as and when the same shall 
become due and payable, including all taxes, assessments and governmental 
charges upon it or any of its properties, assets, income or profits, prior to 
the date on which penalties attach thereto, except to the extent that such 
liabilities, including taxes, assessments or charges, are being contested in 
good faith and by appropriate and lawful proceedings diligently conducted and 
for which such reserve or other appropriate provisions, if any, as shall be 
required by GAAP shall have been made, but only to the extent that failure to 
discharge any such liabilities would not result in a Material Adverse Change, 
PROVIDED that the Loan Parties and their Subsidiaries will pay all such 
liabilities (which have not promptly been stayed or enjoined) forthwith upon 
the commencement of proceedings to foreclose any Lien which may have attached 
as security therefor.

          8.1.3     MAINTENANCE OF INSURANCE.

               Each Loan Party shall, and shall cause each of its 
Subsidiaries to, insure its properties and assets against loss or damage by 
fire and such other insurable hazards as such assets are commonly insured 
(including fire, extended coverage, property damage, workers' compensation, 
public liability and business interruption insurance) and against other risks 
(including errors and omissions) in such amounts as similar properties and 
assets are insured by prudent companies in similar circumstances carrying on 
similar businesses, and with reputable 

                                     -55-
<PAGE>

and financially sound insurers, including self-insurance to the extent 
customary, all as reasonably determined by the Agent. At the request of the 
Agent, the Loan Parties shall deliver to the Agent (x) on the Closing Date

Agent, which shall (i) specify the Agent as an additional insured, mortgagee 
and lender loss payee as its interests may appear, with the understanding 
that any obligation imposed upon the insured (including the liability to pay 
premiums) shall be the sole obligation of the applicable Loan Parties and not 
that of the insured, (ii) provide that the interest of the Banks shall be 
insured regardless of any breach or violation by the applicable Loan Parties 
of any warranties, declarations or conditions contained in such policies or 
any action or inaction of the applicable Loan Parties or others insured under 
such policies, (iii) provide a waiver of any right of the insurers to set off 
or counterclaim or any other deduction, whether by attachment or otherwise, 
(iv) provide that any and all rights of subrogation which the insurers may 
have or acquire shall be, at all times and in all respects, junior and 
subordinate to the prior payment in full of the Indebtedness hereunder and 
that no insurer shall exercise or assert any right of subrogation until such 
time as the Indebtedness hereunder has been paid in full and the Commitments 
have terminated, (v) provide, except in the case of public liability 
insurance and workmen's compensation insurance, that all insurance proceeds 
for losses of less than $1,000,000 shall be adjusted with and payable to the

$1,000,000 or more shall be adjusted with and payable to the Agent, (vi) 
include effective waivers by the insurer of all claims for insurance premiums 
against the Agent, (vii) provide that no cancellation of such policies for 
any reason (including non-payment of premium) nor any change therein shall be 
effective until at least thirty (30) days after receipt by the Agent of 
written notice of such cancellation or change, (viii) be primary without 
right of contribution of any other insurance carried by or on behalf of any 
additional insureds with respect to their respective interests in the 
Collateral, and (ix) provide that inasmuch as the policy covers more than one 
insured, all terms, conditions, insuring agreements and endorsements (except 
limits of liability) shall operate as if there were a separate policy 
covering each insured. The applicable Loan Parties shall notify the Agent 
promptly of any occurrence causing a material loss or decline in value of the 
Collateral and the estimated (or actual, if available) amount of such loss or 
decline.

          8.1.4     MAINTENANCE OF PROPERTIES AND LEASES.

               Each Loan Party shall, and shall cause each of its 
Subsidiaries to, maintain in good repair, working order and condition

useful or necessary to its business, and from time to time, such Loan Party 
will make or cause to be made all appropriate repairs, renewals or

Subsidiaries to, maintain in full force and effect all patents, trademarks, 
service marks, trade names, copyrights, licenses, franchises, permits and 
other authorizations necessary for the ownership and operation of its 
properties and business if the failure so to maintain the same would 
constitute a Material Adverse Change.

          8.1.6     VISITATION RIGHTS.

               Each Loan Party shall, and shall cause each of its 
Subsidiaries to, permit any of the officers or authorized employees or 
representatives of the Agent or any of the Banks to visit and inspect any of 
its properties and to examine and make excerpts from its books and records 
and discuss its business affairs, finances and accounts with its officers, 
all in such detail and at such times and as often as any of the Banks may 
reasonably request, PROVIDED that each Bank shall provide the Borrower and 
the Agent with reasonable notice prior to any visit or inspection. In the 
event any Bank desires to conduct an audit of any Loan Party, such Bank shall 
make a reasonable effort to conduct such audit contemporaneously with any 
audit to be performed by the Agent.

          8.1.7     KEEPING OF RECORDS AND BOOKS OF ACCOUNT.

               The Borrower shall, and shall cause each Subsidiary of the 
Borrower to, maintain and keep proper books of record and account which 
enable the Borrower and its Subsidiaries to issue financial statements in 
accordance with GAAP and as otherwise required by applicable Laws of any 
Official Body having jurisdiction over the Borrower or any Subsidiary of the 
Borrower, and in which full, true and correct entries shall be made in all 
material respects of all its dealings and business and financial affairs.

          8.1.8     PLANS AND BENEFIT ARRANGEMENTS.

               The Borrower shall, and shall cause each other member of the 
ERISA Group to, comply with ERISA, the Internal Revenue Code and other 
applicable Laws applicable to Plans and Benefit Arrangements (including 
provisions relating to the qualification of Plans and Benefit Arrangements 
under Section 401 of the Internal Revenue Code), except where such failure, 
alone or in conjunction with any other failure, would not result in a 
Material Adverse Change. Without limiting the generality of the foregoing, 
the Borrower shall cause all of its Plans and all Plans maintained by any 
member of the ERISA Group to be funded in accordance with the minimum funding 
requirements of ERISA and shall make, and cause each member of the ERISA 
Group to make, in a timely manner, all contributions due to Plans, Benefit 
Arrangements and Multiemployer Plans.

          8.1.9     COMPLIANCE WITH LAWS.

               Each Loan Party shall, and shall cause each of its 
Subsidiaries to, comply with all applicable Laws, including all Environmental 
Laws, in all respects, PROVIDED that 

                                     -57-
<PAGE>

it shall not be deemed to be a violation of this Section 8.1.9 if any failure 
to comply with any Law would not result in fines, penalties, remediation 
costs, other similar liabilities or injunctive relief which in the aggregate 
would constitute a Material Adverse Change.

          8.1.10    USE OF PROCEEDS.

               The Loan Parties will use the Letters of Credit and the 
proceeds of the Loans only for general corporate purposes, including (i) for 
working capital, (ii) to fund redemptions of Preferred Stock permitted 
hereunder, (iii) to finance Permitted Acquisitions, or (iv) to repay and 
terminate Indebtedness outstanding under the Existing Credit Agreement. The

for any purposes which contravenes any applicable Law or any provision hereof.

          8.1.11    FURTHER ASSURANCES.

               Each Loan Party shall, from time to time, at its expense, 
faithfully preserve and protect the Agent's Lien on and Prior Security 
Interest in the Collateral as a continuing first priority perfected Lien, 
subject only to Permitted Liens, and shall do such other acts and things as 
the Agent may deem necessary or advisable from time to time in order to

the Banks to the extent provided in this Agreement.

intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable Law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties. Each
Bank expressly acknowledges (i) that the Agent has not made any representations
or warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of any of the Loan Parties, shall be deemed to constitute

which is contrary to this Agreement or any other Loan Document or applicable
Law. In the absence of a request by the Required Banks, the Agent shall have
authority, in its sole discretion, to take or not to take any such action,
unless this Agreement specifically requires the consent of the Required Banks or
all of the Banks. Any action taken or failure to act pursuant to such
instructions or discretion shall be binding on the Banks, subject to Section
10.6 [Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6,

Loan Documents or any action taken or omitted by the Agent hereunder or

failure to give notice does not result in a loss to the Bank), or (c) if the 
same results from a compromise and settlement agreement entered into without 
the consent of such Bank, which shall not be unreasonably withheld. In 
addition, each Bank agrees promptly upon demand to reimburse the Agent (to 
the extent not reimbursed by the Borrower and without limiting the Obligation 
of the Borrower to do so) in proportion to its Ratable Share for all amounts 
due and payable by the Borrower to the Agent in connection with the Agent's 
periodic audit of the Loan Parties' books, records and business properties.

     10.8 RELIANCE BY AGENT.

     The Agent shall be entitled to rely upon any writing, telegram, telex or
teletype message, resolution, notice, consent, certificate, letter, cablegram,
statement, order or other document or conversation by telephone or otherwise
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons, and upon the advice and opinions of counsel and
other professional advisers selected by the Agent. The Agent shall be fully
justified in failing or refusing to take any action hereunder unless it shall
first be indemnified to its satisfaction by the Banks against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

     10.9 NOTICE OF DEFAULT.

     The Agent shall not be deemed to have knowledge or notice of the occurrence
of any Potential Default or Event of Default unless the Agent has received
written notice from a Bank or the Borrower referring to this Agreement,
describing such Potential Default or Event of Default and stating that such
notice is a "notice of default."

     10.10  NOTICES.

     The Agent shall promptly send to each Bank a copy of all notices received
from the Borrower pursuant to the provisions of this Agreement or the other Loan
Documents promptly upon receipt thereof. The Agent shall promptly notify the
Borrower and the other Banks of each change in the Base Rate and the effective
date thereof.

     10.11 BANKS IN THEIR INDIVIDUAL CAPACITIES.

     With respect to its Revolving Credit Commitment and the Revolving Credit
Loans made by it and any other rights and powers given to it as a Bank hereunder
or under any of the other Loan Documents, the Agent shall have the same rights
and powers hereunder as any 


                                     -84-
<PAGE>

other Bank and may exercise the same as though it were not the Agent, and the 
term "Banks" shall, unless the context otherwise indicates, include the Agent 
in its individual capacity. PNC Bank and its Affiliates and each of the Banks 
and their respective Affiliates may, without liability to account, except as 
prohibited herein, make loans to, accept deposits from, discount drafts for, 
act as trustee under indentures of, and generally engage in any kind of 
banking or trust business with, the Loan Parties and their Affiliates, in the 
case of the Agent, as though it were not acting as Agent hereunder and in the 
case of each Bank, as though such Bank were not a Bank hereunder. The Banks 
acknowledge that, pursuant to such activities, the Agent or its Affiliates 
may (i) receive information regarding the Loan Parties (including information 
that may be subject to confidentiality obligations in favor of the Loan 
Parties) and acknowledge that the Agent shall be under no obligation to 
provide such information to them, and (ii) accept fees and other 
consideration from the Loan Parties for services in connection with this 
Agreement and otherwise without having to account for the same to the Banks.

     10.12  HOLDERS OF NOTES.

     The Agent may deem and treat any payee of any Note as the owner thereof for
all purposes hereof unless and until written notice of the assignment or
transfer thereof shall have been filed with the Agent. Any request, authority or
consent of any Person who at the time of making such request or giving such
authority or consent is the holder of any Note shall be conclusive and binding
on any subsequent holder, transferee or assignee of such Note or of any Note or
Notes issued in exchange therefor.

     10.13  EQUALIZATION OF BANKS.

     The Banks and the holders of any participations in any Notes agree among
themselves that, with respect to all amounts received by any Bank or any such
holder for application on any Obligation hereunder or under any Note or under
any such participation, whether received by voluntary payment, by realization
upon security, by the exercise of the right of set-off or banker's lien, by
counterclaim or by any other non-pro rata source, equitable adjustment will be
made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Banks and such holders in
proportion to their interests in payments under the Notes, except as otherwise
provided in Section 4.4.3 [Agent's and Bank's Rights], 5.4.2 [Replacement of a
Bank] or 5.5 [Additional Compensation in Certain Circumstances]. The Banks or
any such holder receiving any such amount shall purchase for cash from each of
the other Banks an interest in such Bank's Loans in such amount as shall result
in a ratable participation by the Banks and each such holder in the aggregate
unpaid amount under the Notes, PROVIDED that if all or any portion of such
excess amount is thereafter recovered from the Bank or the holder making such
purchase, such purchase shall be rescinded and the purchase price restored to
the extent of such recovery, together with interest or other amounts, if any,
required by law (including court order) to be paid by the Bank or the holder
making such purchase.

<PAGE>

     10.14  SUCCESSOR AGENT.

     The Agent (i) may resign as Agent or (ii) shall resign if such resignation
is requested by the Required Banks (if the Agent is a Bank, the Agent's Loans
and its Commitment shall be considered in determining whether the Required Banks
have requested such resignation) or required by Section 5.4.2 [Replacement of a
Bank], in either case of(i) or (ii) by giving not less than thirty (30) days'
prior written notice to the Borrower. If the Agent shall resign under this
Agreement, then either (a) the Required Banks shall appoint from among the Banks
a successor agent for the Banks, subject to the consent of the Borrower, such
consent not to be unreasonably withheld, or (b) if a successor agent shall not
be so appointed and approved within the thirty (30) day period following the
Agent's notice to the Banks of its resignation, then the Agent shall appoint,
with the consent of the Borrower, such consent not to be unreasonably withheld,
a successor agent who shall serve as Agent until such time as the Required Banks
appoint and the Borrower consents to the appointment of a successor agent. Upon
its appointment pursuant to either clause (a) or (b) above, such successor agent
shall succeed to the rights, powers and duties of the Agent, and the term
"Agent" shall mean such successor agent, effective upon its appointment, and the
former Agent's rights, powers and duties as Agent shall be terminated without
any other or further act or deed on the part of such former Agent or any of the
parties to this Agreement. After the resignation of any Agent hereunder, the
provisions of this Section 10 shall inure to the benefit of such former Agent
and such former Agent shall not by reason of such resignation be deemed to be
released from liability for any actions taken or not taken by it while it was an
Agent under this Agreement.

     10.15  AGENT'S FEE.

     The Borrower shall pay to the Agent a nonrefundable fee (the "Agent's Fee")
under the terms of a letter (the "Agent's Letter") between the Borrower and
Agent, as amended from time to time.

     10.16  AVAILABILITY OF FUNDS.

     The Agent may assume that each Bank has made or will make the proceeds of a
Loan available to the Agent unless the Agent shall have been notified by such
Bank on or before the later of the close of Business on the Business Day
preceding the Borrowing Date with respect to such Loan or two (2) hours before
the time on which the Agent actually funds the proceeds of such Loan to the
Borrower (whether using its own funds pursuant to this Section 10.16 or using
proceeds deposited with the Agent by the Banks and whether such funding occurs
before or after the time on which Banks are required to deposit the proceeds of
such Loan with the Agent). The Agent may, in reliance upon such assumption (but
shall not be required to), make available to the Borrower a corresponding
amount. If such corresponding amount is not in fact made available to the Agent
by such Bank, the Agent shall be entitled to recover such amount on demand from
such Bank (or, if such Bank fails to pay such amount forthwith upon such demand
from the Borrower) together with interest thereon, in respect of each day during
the period commencing on the date such amount was made available to the Borrower
and ending on the date the Agent recovers such amount, at a rate per annum equal
to (i) the Federal Funds Effective Rate during 


                                     -86-

<PAGE>

the first three (3) days after such interest shall begin to accrue and (ii) 
the applicable interest rate in respect of such Loan after the end of such 
three-day period.

     10.17 CALCULATIONS.

     In the absence of gross negligence or willful misconduct, the Agent shall
not be liable for any error in computing the amount payable to any Bank whether
in respect of the Loans, fees or any other amounts due to the Banks under this
Agreement. In the event an error in computing any amount payable to any Bank is
made, the Agent, the Borrower and each affected Bank shall, forthwith upon
discovery of such error, make such adjustments as shall be required to correct
such error, and any compensation therefor will be calculated at the Federal
Funds Effective Rate.

     10.18  BENEFICIARIES.

     Except as expressly provided herein, the provisions of this Section 10 are
solely for the benefit of the Agent and the Banks, and the Loan Parties shall
not have any rights to rely on or enforce any of the provisions hereof. In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be deemed to have
assumed any obligation toward or relationship of agency or trust with or for any
of the Loan Parties.


                         11.  MISCELLANEOUS

     11.1  MODIFICATIONS, AMENDMENTS OR WAIVERS.


     With the written consent of the Required Banks, the Agent, acting on behalf
of all the Banks, and the Borrower, on behalf of the Loan Parties, may from time
to time enter into written agreements amending or changing any provision of this
Agreement or any other Loan Document or the rights of the Banks or the Loan
Parties hereunder or thereunder, or may grant written waivers or consents to a
departure from the due performance of the Obligations of the Loan Parties
hereunder or thereunder. Any such agreement, waiver or consent made with such
written consent shall be effective to bind all the Banks and the Loan Parties;
PROVIDED, that, without the written consent of all the Banks, no such agreement,
waiver or consent may be made which will:

          11.1.1    INCREASE OF COMMITMENT; EXTENSION OR EXPIRATION DATE.

               Increase the amount of the Commitment of any Bank hereunder or
extend the Expiration Date;


                                     -87-

<PAGE>

          11.1.2    EXTENSION OF PAYMENT; REDUCTION OF PRINCIPAL INTEREST OR
FEES; MODIFICATION OF TERMS OF PAYMENT.

               Whether or not any Loans are outstanding, extend the time for
payment of principal or interest of any Loan (excluding the due date of any
mandatory prepayment of a Loan or any mandatory Commitment reduction in
connection with such a mandatory prepayment hereunder except for mandatory
reductions of the Commitments on the Expiration Date), the Commitment Fee or any
other fee payable to any Bank, or reduce the principal amount of or the rate of
interest borne by any Loan or reduce the Commitment Fee or any other fee payable
to any Bank, or otherwise affect the terms of payment of the principal of or
interest of any Loan, the Commitment Fee or any other fee payable to any Bank;

          11.1.3  RELEASE OF COLLATERAL OR GUARANTOR.

               Except for sales of assets permitted by Section 8.2.7
[Disposition of Assets or Subsidiaries], release any Collateral consisting of
capital stock or other ownership interests of any Loan Party or its Subsidiary
or substantially all of the assets of any Loan Party, or any Guarantor from its
Obligations under the Guaranty Agreement; or

               11.1.4  MISCELLANEOUS

               Amend Section 5.2 [Pro Rata Treatment of Banks], 10.6
[Exculpatory Provisions, Etc.] or 10.13 [Equalization of Banks] or this Section
11.1, alter any provision regarding the pro rata treatment of the Banks, change
the definition of Required Banks, or change any requirement providing for the
Banks or the Required Banks to authorize the taking of any action hereunder;

PROVIDED, further, that no agreement, waiver or consent which would modify the
interests, rights or obligations of the Agent in its capacity as Agent or as the
issuer of Letters of Credit shall be effective without the written consent of
the Agent.

     11.2 NO IMPLIED WAIVERS; CUMULATIVE REMEDIES; WRITING REQUIRED.

     No course of dealing and no delay or failure of the Agent or any Bank in
exercising any right, power, remedy or privilege under this Agreement or any
other Loan Document shall affect any other or future exercise thereof or operate
as a waiver thereof, nor shall any single or partial exercise thereof or any
abandonment or discontinuance of steps to enforce such a right, power, remedy or
privilege preclude any further exercise thereof or of any other right, power,
remedy or privilege. The rights, remedies, powers and privileges of the Agent
and the Banks under this Agreement and any other Loan Documents are cumulative
and not exclusive of any rights, remedies, powers and privileges which they
would otherwise have. Any waiver, permit, consent or approval of any kind or
character on the part of any Bank of any breach or default under this Agreement
or any such waiver of any provision or condition of this Agreement must be in
writing and shall be effective only to the extent specifically set forth in such
writing.

     11.3 REIMBURSEMENT AND INDEMNIFICATION OF BANKS BY THE BORROWER; TAXES.

     The Borrower agrees unconditionally upon demand to pay or reimburse to each
Bank (other than the Agent, as to which the Borrower's Obligations are set forth
in Section 10.5 [Reimbursement and Indemnification of Agent by the Borrower])
and to save such Bank harmless against (i) liability for the payment of all
reasonable out-of-pocket costs, expenses and disbursements (including fees and
expenses of counsel), incurred by such Bank (a) in connection with the
enforcement of this Agreement or any other Loan Document, or collection of
amounts due hereunder or thereunder or the proof and allowability of any claim
arising under this Agreement or any other Loan Document, whether in bankruptcy
or receivership proceedings or otherwise, and (b) in any workout or
restructuring or in connection with the protection, preservation, exercise or
enforcement of any of the terms hereof or of any rights hereunder or under any
other Loan Document or in connection with any foreclosure, collection or
bankruptcy proceedings, or (ii) all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against such Bank, in its capacity as such, in any way relating to or arising
out of this Agreement or any other Loan Documents or any action taken or omitted
by such Bank hereunder or thereunder, PROVIDED that the Borrower shall not be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements (A) if
the same results from such Bank's gross negligence or willful misconduct, or (B)
if the Borrower was not given notice of the subject claim and the opportunity to
participate in the defense thereof, at its expense (except that the Borrower
shall remain liable to the extent such failure to give notice does not result in
a loss to the Borrower), or (C) if the same results from a compromise or
settlement agreement entered into without the consent of the Borrower, which
shall not be unreasonably withheld. The Banks will attempt to minimize the fees
and expenses of legal counsel for the Banks which are subject to reimbursement
by the Borrower hereunder by considering the usage of one law firm to represent
the Banks and the Agent if appropriate under the circumstances. The Borrower
agrees unconditionally to pay all stamp, document, transfer, recording or filing
taxes or fees and similar impositions now or hereafter determined by the Agent
or any Bank to be payable in connection with this Agreement or any other Loan
Document, and the Borrower agrees unconditionally to save the Agent and the
Banks harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions. For the purposes of this
Section 11.3, all references to any Bank or the Banks shall be deemed to include
Bank Of America National Trust and Savings Association, N.A. in its capacity as
the Co-Agent and Bank Of America National Trust and Savings Association, N.A. in
its capacity as the Co-Agent shall be afforded all of the rights given to any
Bank in this Section.

     11.4 HOLIDAYS.

     Whenever payment of a Loan to be made or taken hereunder shall be due on a
day which is not a Business Day such payment shall be due on the next Business
Day and such extension of time shall be included in computing interest and fees,
except that the Loans shall be due on the Business Day preceding the Expiration
Date if the Expiration Date is not a Business Day. Whenever any payment or
action to be made or taken hereunder (other than payment of the 


                                     -89-

<PAGE>

Loans) shall be stated to be due on a day which is not a Business Day, such 
payment or action shall be made or taken on the next following Business Day 
(except as provided in Section 4.2 [Interest Periods] with respect to 
Interest Periods under the Euro-Rate Option), and such extension of time 
shall not be included in computing interest or fees, if any, in connection 
with such payment or action.

     11.5 FUNDING BY BRANCH, SUBSIDIARY OR AFFILIATE.

          11.5.1    NATIONAL FUNDING.

               Each Bank shall have the right from time to time, without notice
to the Borrower, to deem any branch, Subsidiary or Affiliate (which for the
purposes of this Section 11.5 shall mean any corporation or association which is
directly or indirectly controlled by or is under direct or indirect common
control with any corporation or association which directly or indirectly
controls such Bank) of such Bank to have made, maintained or funded any Loan to
which the Euro-Rate Option applies at any time, PROVIDED that immediately
following (on the assumption that a payment were then due from the Borrower to
such other office), and as a result of such change, the Borrower would not be
under any greater financial obligation pursuant to Section 5.5 [Additional
Compensation in Certain Circumstances] than it would have been in the absence of
such change. Notional funding offices may be selected by each Bank without
regard to such Bank's actual methods of making, maintaining or funding the Loans
or any sources of funding actually used by or available to such Bank.

          11.5.2    ACTUAL FUNDING.

               Each Bank shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Bank to make or maintain such Loan subject to the last sentence of this Section
11.5.2. If any Bank causes a branch, Subsidiary or Affiliate to make or maintain
any part of the Loans hereunder, all terms and conditions of this Agreement
shall, except where the context clearly requires otherwise, be applicable to
such part of the Loans to the same extent as if such Loans were made or
maintained by such Bank, but in no event shall any Bank's use of such a branch,
Subsidiary or Affiliate to make or maintain any part of the Loans hereunder
cause such Bank or such branch, Subsidiary or Affiliate to incur any cost or
expenses payable by the Borrower hereunder or require the Borrower to pay any
other compensation to any Bank (including any expenses incurred or payable
pursuant to Section 5.5 [Additional Compensation in Certain Circumstances])
which would otherwise not be incurred.

     11.6 NOTICES.

     All notices, requests, demands, directions and other communications (as
used in this Section 11.6, collectively referred to as "Notices") given to or
made upon any party hereto under the provisions of this Agreement shall be by
telephone or in writing (including telex or facsimile communication) unless
otherwise expressly permitted hereunder and shall be delivered or sent by telex
or facsimile to the respective parties at the addresses and numbers set forth
under 


                                     -90-

their respective names on SCHEDULE 1.1(B) hereof or in accordance with any 
subsequent unrevoked Notice from any party to the others. All Notices shall, 
except as otherwise expressly herein provided, be effective (a) in the case 
of telex or facsimile, when received, (b) in the case of hand-delivered 
Notice, when hand-delivered, (c) in the case of telephone, when telephoned, 
PROVIDED, however, that in order to be effective, telephonic Notices must be 
confirmed in writing no later than the next day by letter, facsimile or 
telex, (d) if given by mail, four (4) days after such communication is 
deposited in the mail with first-class postage prepaid, certified or 
registered mail, return receipt requested, and (e) if given by any other 
means (including by air courier), when delivered; PROVIDED, that Notices to 
the Agent shall not be effective until received. Any Bank giving any Notice 
to any Loan Party shall simultaneously send a copy thereof to the Agent, and 
the Agent shall promptly notify the other Banks of the receipt by it of any 
such Notice.

     11.7 SEVERABILITY.

     The provisions of this Agreement are intended to be severable. If any
provision of this Agreement shall be held invalid or unenforceable in whole or
in part in any jurisdiction, such provision shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without in any
manner affecting the validity or enforceability thereof in any other
jurisdiction or the remaining provisions hereof in any jurisdiction.

     11.8 GOVERNING LAW.

     Each Letter of Credit and Section 2.10 [Letter of Credit Subfacility] shall
be subject to the Uniform Customs and Practice for Documentary Credits (1993
Revision), International Chamber of Commerce Publication No. 500, as the same
may be revised or amended from time to time, and to the extent not inconsistent
therewith, the internal laws of the Commonwealth of Pennsylvania without regard
to its conflict of laws principles, and the balance of this Agreement shall be
deemed to be a contract under the Laws of the Commonwealth of Pennsylvania and
for all purposes shall be governed by and construed and enforced in accordance
with the internal laws of the Commonwealth of Pennsylvania without regard to its
conflict of laws principles.

     11.9 PRIOR UNDERSTANDING.

     This Agreement and the other Loan Documents supersede all prior
understandings and agreements, whether written or oral, between the parties
hereto and thereto relating to the transactions provided for herein and therein,
including any prior confidentiality agreements and commitments.

     11.10     DURATION; SURVIVAL.

     All representations and warranties of the Loan Parties contained herein or
made in connection herewith shall survive the making of Loans and issuance of
Letters of Credit and shall not be waived by the execution and delivery of this
Agreement, any investigation by the 


                                     -91-

<PAGE>

Agent or the Banks, the making of Loans, issuance of Letters of Credit, or 
payment in full of the Loans. All covenants and agreements of the Loan 
Parties contained in Sections 8.1 [Affirmative Covenants], 8.2 
[Negative Covenants] and 8.2.20 [Reporting Requirements] herein shall 
continue in full force and effect from and after the date hereof so long as 
the Borrower may borrow or request Letters of Credit hereunder and until 
termination of the Commitments and payment in full of the Loans and 
expiration or termination of all Letters of Credit. All covenants and 
agreements of the Borrower contained herein relating to the payment of 
principal, interest, premiums, additional compensation or expenses and 
indemnification, including those set forth in the Notes, Section 5 [Payments] 
and Sections 10.5 [Reimbursement and Indemnification of Agent by the Borrower],
10.7 [Reimbursement and Indemnification of Agent by the Banks] and 11.3 
[Reimbursement and Indemnification of Banks by the Borrower, Etc.], shall 
survive payment in full of the Loans, expiration or termination of the 
Letters of Credit and termination of the Commitments.

     11.11  SUCCESSORS AND ASSIGNS.

                    (i)  This Agreement shall be binding upon and shall inure to
the benefit of the Banks, the Agent, the Loan Parties and their respective
successors and assigns, except that none of the Loan Parties may assign or
transfer any of its rights and Obligations hereunder or any interest herein.
Each Bank may, at its own cost, make assignments of or sell participations in
all or any part of its Commitments and the Loans made by it to one or more banks
or other entities, subject to the consent of the Borrower and the Agent with
respect to any assignee, such consent not to be unreasonably withheld, PROVIDED
that (1) no consent of the Borrower shall be required (A) if an Event of Default
exists and is continuing, or (B) in the case of an assignment by a Bank to an
Affiliate of such Bank, and (2) any assignment by a Bank to a Person other than
an Affiliate of such Bank may not be made in amounts of Revolving Credit
Commitments less than the lesser of $5,000,000 or the amount of the assigning
Bank's Revolving Credit Commitment. In the case of an assignment, upon receipt
by the Agent of the Assignment and Assumption Agreement, the assignee shall
have, to the extent of such assignment (unless otherwise provided therein), the
same rights, benefits and obligations as it would have if it had been a
signatory Bank hereunder, the Commitments shall be adjusted accordingly, and
upon surrender of any Note subject to such assignment, the Borrower shall
execute and deliver a new Note to the assignee in an amount equal to the amount
of the Revolving Credit Commitment assumed by it and a new Revolving Credit Note
to the assigning Bank in an amount equal to the Revolving Credit Commitment
retained by it hereunder. Any Bank which assigns any or all of its Commitment or
Loans to a Person other than an Affiliate of such Bank shall pay (or cause to be
paid by the assignee) to the Agent a service fee in the amount of $3,500 for
each assignment. In the case of a participation, the participant shall only have
the rights specified in Section 9.2.3 [Set-off] (the participant's rights
against such Bank in respect of such participation to be those set forth in the
agreement executed by such Bank in favor of the participant relating thereto and
not to include any voting rights except with respect to changes of the type
referenced in Sections 11.1.1 [Increase of Commitment, Etc.], 11.1.2 [Extension
of Payment, Etc.], or 11.1.3 [Release of Collateral or Guarantor], all of such
Bank's obligations under this Agreement or any 


                                     -92-

<PAGE>

other Loan Document shall remain unchanged, and all amounts payable by any 
Loan Party hereunder or thereunder shall be determined as if such Bank had 
not sold such participation.

                    (ii) Any assignee or participant which is not incorporated
under the Laws of the United States of America or a state thereof shall deliver
to the Borrower and the Agent the form of certificate described in Section 11.17
[Tax Withholding Clause] relating to federal income tax withholding. Each Bank
may furnish any publicly available information concerning any Loan Party or its
Subsidiaries and any other information concerning any Loan Party or its
Subsidiaries in the possession of such Bank from time to time to assignees and
participants (including prospective assignees or participants), PROVIDED that
such assignees and participants agree to be bound by the provisions of Section
11.12 [Confidentiality].

                    (iii) Notwithstanding any other provision in this Agreement,
any Bank may at any time pledge or grant a security interest in all or any
portion of its rights under this Agreement, its Note and the other Loan
Documents to any Federal Reserve Bank in accordance with Regulation A of the FRB
or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or consent
of the Borrower or the Agent. No such pledge or grant of a security interest
shall release the transferor Bank of its obligations hereunder or under any
other Loan Document.

     11.12     CONFIDENTIALITY.

          11.12.1   GENERAL.

               The Agent and the Banks each agree to keep confidential all
information obtained from any Loan Party or its Subsidiaries which is nonpublic,
confidential or proprietary in nature (including any information the Borrower
specifically designates as confidential), except as provided below, and to use
such information only in connection with their respective capacities under this
Agreement and for the purposes contemplated hereby. The Agent and the Banks
shall be permitted to disclose such information (i) to outside legal counsel,
accountants and other professional advisors who need to know such information in
connection with the administration and enforcement of this Agreement, subject to
agreement of such Persons to maintain the confidentiality, (ii) to assignees and
participants as contemplated by Section 11.11 or as provided in Section 11.12.2,
(iii) to the extent requested by any bank regulatory authority or, with notice
to the Borrower, as otherwise required by applicable Law or by any subpoena or
similar legal process, or in connection with any investigation or proceeding
arising out of the transactions contemplated by this Agreement, (iv) if it
becomes publicly available other than as a result of a breach of this Agreement
or becomes available from a source not known to be subject to confidentiality
restrictions, or (v) if the Borrower shall have consented to such disclosure.
