INTRODUCTION

Wolverine Tube, Inc. ("Wolverine" or the "Company") is a leading North American
manufacturer and distributor of copper and copper alloy tube, and other tubular
products, and believes that it offers the broadest product line of any North
American tube manufacturer. The Company also manufactures and distributes
copper and copper alloy rod, bar and strip products. The Company believes that
in 1998 it was the largest North American producer of copper and copper alloy
tube for commercial products.

Copper's unique attributes--thermal conductivity, ease of bending and joining,
and resistance to erosion and corrosion--make it an attractive material for a
broad range of applications in a large number of diverse industries. The
Company's focus is on custom-engineered, high value-added copper and copper
alloy tube, which enhances performance and energy efficiency in many
applications. Customers include commercial and residential air conditioning and
refrigeration equipment manufacturers, appliance manufacturers, automotive
manufacturers, industrial equipment manufacturers, utilities and other power
generating companies, refining and chemical processing companies and plumbing
wholesalers.

HISTORY AND STRUCTURE

The Company is the successor to a business founded in Detroit in 1916. In 1987,
the Company was purchased through a leveraged acquisition of substantially all
the assets of the seamless copper tube business of The Henley Group, Inc. and
its Canadian affiliates by an investor group that included the then-existing
management of the Company. In 1988, the Company's wholly-owned subsidiary,
Wolverine Tube (Canada) Inc. ("Wolverine Canada"), acquired substantially all
of the assets of Noranda Metal Industries Limited, a Canadian company. In
January 1991, Genstar Capital Corporation ("Genstar") acquired a controlling
interest in the Company. At that time, Genstar owned 72.8% of the Common Stock
with the balance of the Common Stock owned by the management of the Company
(the "Management Stockholders") and certain other investors.

In August 1993, the Company and certain stockholders engaged in an initial
public offering of 6,555,000 shares of Common Stock. Of those shares, 3,280,000
were sold by Wolverine and 3,275,000 were sold by certain stockholders. Net
proceeds to the Company were approximately $46.4 million.

In November 1994, the Company completed its acquisition of Small Tube Products
Company, Inc. ("STP"), a fabricated copper and copper alloy products
manufacturer based in Altoona, Pennsylvania, by means of a merger of a
wholly-owned subsidiary of the Company with and into STP. The Company acquired
all of the outstanding stock of STP in exchange for $54.6 million in cash and
400,000 shares of Wolverine Common Stock. As a result of the merger, STP became
a wholly-owned subsidiary of Wolverine and was renamed "STPC Holding, Inc."


                                       1
<PAGE>   4


In September 1995, the Company completed a secondary public offering of
4,882,700 shares of Common Stock (the "Secondary Stock Offering") in which
Genstar and its affiliates sold substantially all of their shares of Common
Stock. No additional shares of Common Stock were issued by the Company in
conjunction with the Secondary Stock Offering.

In September 1996, the Company completed the acquisition of Tube Forming, Inc.,
a manufacturer of value-added copper fabricated products based in Carrollton,
Texas, for $34.6 million in cash.


In May 1998, the Company acquired a 240,000 square foot welded tube
manufacturing facility located in Jackson, Tennessee, and the related equipment
and technology, from Korea-based Poongsan Corporation, for approximately $35.4
million in cash.

The Company, a Delaware corporation, was organized in 1987. The Company's
principle executive offices are located at 1525 Perimeter Parkway, Suite 210,
Huntsville, Alabama 35806, and its telephone number is (256) 353-1310.

PRODUCTS

COMMERCIAL PRODUCTS

The Company includes in the commercial products category several types of
technically sophisticated tube and fabricated tubular products that it sells
directly to equipment manufacturers and that are generally custom designed and
manufactured. Because of the high level of added value, profitability tends to
be higher for commercial products than for the Company's other products.

The Company's commercial products include:

Industrial Tube. Small (as small as .01") and medium diameter copper tube used
primarily by residential air conditioning, appliance and refrigeration
equipment manufacturers is known as "industrial" tube. Industrial tube is made
to customer specifications for equipment manufacturing. The Company's
industrial tube products include coils in lengths of up to one mile (to permit
economical transport to customers for further processing), smooth straight
tube, internally enhanced tube with internal surface ridges to increase heat
transfer in air conditioning coils, and very small diameter capillary tube (for
control valve applications).

Technical Tube. Technical tube is used to increase heat transfer in large
commercial air conditioners, heat exchangers for power generating and chemical
processing plants, water heaters, swimming pool and spa heaters and large
industrial equipment oil coolers. Small, wedge-like grooves (fins) on the outer
surface, together with internal enhancements of technical tube, increase
surface area and refrigerant agitation, thereby increasing heat transfer
efficiency. The Company was the first to develop integral finned tube, in which
the fins are formed directly from the wall of the tube, and holds many patents
in that area.

Copper Alloy Tube. Copper alloy tube (principally copper mixed with nickel) is
manufactured for certain severe uses and corrosive environments such as
condenser tubes and heat exchangers


                                       2
<PAGE>   5


in power generating plants, chemical plants, refineries and ships. The
Company's copper alloy tube products include smooth and surface enhanced tube
produced from a variety of alloys, U-bends for heat exchangers and the
Company's patented Korodense(R) corrugated heat transfer tube. Also included in
the alloy tube category are surface enhanced titanium and steel tube produced
by the Company from smooth tube supplied by outside sources.

Fabricated Products. Fabricated products encompass a wide variety of copper,
copper alloy and aluminum tubing for a myriad of different applications. Tubing
can be supplied in various cut lengths, long straight lengths or coils.
Specialty fabricated parts, sub-assemblies and components (such as return bends
and manifolds) are also produced. Capabilities include cutting, bending,
swaging, flaring, end-finishing and brazing, which can be applied to a wide
range of products.

WHOLESALE PRODUCTS

Wholesale products include plumbing tube and refrigeration service tube.
Plumbing tube and refrigeration service tube are produced in standard sizes and
lengths primarily for plumbing, air conditioning and refrigeration service
applications. Many major competitors manufacture the most common 3/4" and 1/2"
diameter plumbing tube. These products are considered commodity products
because price and delivery are the primary competitive factors. Plumbing tube
and refrigeration service tube are sold primarily through wholesalers.

ROD, BAR AND STRIP PRODUCTS

Copper and Copper Alloy Rod and Bar. Copper and copper alloy rod and bar
products include a broad range of copper and copper alloy solid products,
including round, rectangular, hexagonal and specialized shapes. Brass rod and
bar are used by industrial equipment and machinery manufacturers for valves,
fittings and plumbing goods. Copper bars are used in electrical distribution
systems and switchgear.

Copper and Copper Alloy Strip. Copper and copper alloy strip products are used
primarily by automotive, hardware and electrical equipment manufacturers, by
roofing contractors and by mints for coins. Copper and copper alloy strip
products are sold directly to manufacturers and to service centers that keep an
inventory of standard sizes.

PHASEOUT OF CFCS

In September 1987, the United States, Canada and many other countries signed
The Montreal Protocol on Substances that Deplete the Ozone Layer (the "Montreal
Protocol"). As originally drafted, the Montreal Protocol provided for the
limitation on production and consumption of chlorofluorocarbons ("CFCs") over
various periods of time. On November 15, 1990, the President of the United
States signed The Clean Air Act Amendments of 1990 (the "1990 Amendments").
Title VI, Section 604 of the Clean Air Act (the "Act") requires the phaseout of
CFCs (other than methyl chloroform) by the year 2000. On November 23, 1992, the
fourth meeting of the parties to the Montreal Protocol was convened in
Copenhagen. At that meeting the parties agreed, among other things, to
accelerate the phaseout of CFC production to January 1, 1996. On December 10,
1993, the United States Environmental Protection Agency (the


                                       3
<PAGE>   6


"EPA") promulgated regulations requiring domestic producers to cease
production of CFCs by January 1, 1996.

The 1990 Amendments, the Montreal Protocol and the EPA regulations generally
contain exceptions for essential uses of CFCs and permit recycling. CFCs are
used as refrigerants in major air conditioning and refrigeration applications
(other than household air conditioning and refrigeration units, which rely
exclusively on hydrochlorofluorocarbon-22). Alternatives to CFCs include
hydrofluorocarbons ("HFCs"), hydrochlorofluorocarbons ("HCFCs"), and, to a
lesser extent, ammonia. HFCs and HCFCs are generally less efficient
refrigerants than CFCs.

The Company has benefited and expects to continue to benefit from the CFC
phaseout as existing large commercial air conditioners ("chillers") are
replaced over the next five to seven years with units utilizing alternative
refrigerants. Based upon data from the EPA and the Air Conditioning and
Refrigeration Institute ("ARI"), the Company estimates that there are
approximately 130,000 large industrial chillers worldwide, including 80,000
large industrial chillers in North America, that are affected by the 1990
Amendments and the Montreal Protocol. Industry sources estimate that as of
December 31, 1998, there were approximately 51,000 large industrial chillers in
North America that have not been replaced or retrofitted. These chillers are
used to regulate the temperature and humidity in offices, hotels, shopping
centers and other large buildings.

The Company expects demand for its high value-added, energy efficient tubes to
increase as manufacturers produce more energy efficient and lower operating
cost units and as existing chillers are replaced in response to the ban on
production of CFCs. There can be no assurance that this anticipated demand will
materialize, or that the Company will not face increased competition, with an
adverse effect on profitability, from other manufacturers in this high
value-added segment. In addition, new refrigerants or technologies that are not
compatible with copper tube may be developed in response to the requirements of
the 1990 Amendments, the Montreal Protocol and the EPA regulations. The
development of any such new refrigerant or technology could have a material
adverse effect on the Company's business, operating results or financial
condition. Furthermore, there can be no assurance that the use of reclaimed
CFCs to a greater extent than anticipated will not continue, causing a slower
pace of replacement and retrofitting of chillers currently using CFCs.

KEY CUSTOMERS

York International accounted for 10% of the Company's consolidated net sales in
1998 and 11% of the Company's consolidated net sales in 1996. No customer
accounted for as much as 10% of the Company's consolidated net sales in 1997.

BACKLOG

A significant part of the Company's sales are based on short-term purchase
orders. For this reason, the Company does not maintain a backlog and believes
that backlog is not necessarily a meaningful indicator of future results. A
significant and increasing amount of the Company's sales result from
"partnership" relationships wherein the Company provides a high degree of
specialized service and generally becomes the largest supplier of a customer's
copper tube requirements. Under these arrangements, the Company's customers
provide forecasts of their requirements, against which purchase orders are
periodically released. While these relationships do not involve long-term
supply or purchase contracts from either party, they have provided the Company
with an increased degree of order flow predictability.

SALES AND MARKETING

The Company generally uses a direct field sales force rather than the
agent-based approach used by many of its competitors. The Company believes its
direct sales force forms a critical link in the communication between the
Company and its customers. This link is particularly important in the high
value-added product segments, in which the Company often works with customers
in their product enhancement and new product development efforts.


                                       5
<PAGE>   8


North America. The sales force in North America consists of sales officers and
field marketing representatives who are responsible for selling and servicing
accounts for the entire product line. The sales force also consists of regional
managers located in Dallas, Texas and London, Ontario. The sales force in North
America is coordinated by the Vice President of Sales, who is located in the
Company's offices in Decatur, Alabama.

International. The Company's overseas export sales are carried out both
directly with major overseas customers and through foreign agents. These sales
are coordinated by the Vice President of International Operations from the
Company's offices in Huntsville, Alabama. The Company has sales, marketing and
business development offices in Lyon, France, Leeds, England and Hong Kong.

For information concerning the amount of sales, gross profit and certain other
financial information about foreign and domestic operations see Note 16 of the
Notes to Consolidated Financial Statements.

COMPETITION

While no single company competes with Wolverine in all of the Company's product
lines, the Company faces significant competition in each of its product lines.
The Company has numerous competitors, some of which are larger and have greater
financial resources than the Company. Cerro Copper Products Co., Inc. ("Cerro"),
Industrias Nacobre S.A. de C.V., Kobe Copper Products Inc., Mueller Industries
Inc., Olin Corporation, Outokumpu American Brass Company, Wieland-Werke
Metallwerke and others compete with the Company in one or more product lines.
There can be no assurance that the Company will be able to compete successfully
or that competition will not have an adverse effect on the Company's business
operating results or financial condition. Minimal product differentiation among
competitors in the Company's wholesale and rod, bar and strip product lines
creates a pricing structure for these products resembling "commodity" pricing
(i.e., a pricing structure where customers differentiate between products almost
exclusively on price). In these product areas, certain of the Company's
competitors have significantly larger market shares than the Company, and tend
to be the industry pricing leaders. If the Company's competitors in these
product lines were to significantly reduce prices, the Company's business,
operating results or financial condition could be adversely affected.

The Company currently faces limited competition for certain high value-added
commercial products. If other companies, or some of the Company's existing
customers, begin or expand operations in these product categories, the
Company's business, operating results or financial condition could be adversely
affected. Because the Company competes primarily on the basis of the technical
advantages of its commercial products, technical improvements by competitors
could reduce the Company's competitive advantage in these product lines and
thereby adversely affect the Company's business, operating results or financial
condition. The Company could also be adversely affected if new technologies
emerge in the refrigeration industry, or other consumer industries, including
technologies developed in response to the elimination of CFCs, which would
reduce or eliminate the need for copper and copper alloy tube. Certain of the
Company's products, such as plumbing tube, compete with products made of
alternative substances, such as polybutylene plastic. A substantial increase in
the price of copper could


                                       6

decrease the relative attractiveness of copper products in cases where an
alternative exists and thereby adversely affect the Company's business,
operating results or financial condition.

MANUFACTURING

The manufacture of seamless tube and tubular products consists of casting,
extruding, drawing, forming and finishing processes. In most cases, the raw
material is first cast into a solid cylindrical shape or "billet". The billet
is then heated to a high temperature, a hole is pierced through the center of
the cylinder, and the cylinder is then extruded under high pressure into a
tube. At one of the Company's facilities, the raw material is cast directly
into a tubular product. The tube is either drawn to smaller sizes or reduced on
a forging machine and then drawn to smaller sizes. The outside and/or inside
surface can be enhanced to achieve the desired heat transfer qualities.
Depending on customer needs, bending, annealing (heating to restore
flexibility), coiling or other operations may be required to finish the
product.

Virtually all of the tube produced by the Company is seamless as opposed to
welded tube, with the exception of the tube manufactured at the Company's
Jackson, Tennessee location. Welded tube is made from a flat strip that is
rolled and welded together at the edges.

RAW MATERIALS, SUPPLIERS AND PRICING

The Company's principal raw materials are copper, nickel, zinc and tin. In
1998, the Company purchased approximately 357.8 million pounds of metal,
approximately 88% of which was copper. The Company contracts for its copper
requirements with a variety of sources, including producers, merchants,
brokers, dealers and industrial suppliers. The Company's raw materials are
available from a variety of sources, and the Company does not believe that the
loss of any one source would materially affect its business, operating results
or financial condition.

The key elements of the Company's copper procurement and product pricing
strategies are the assurance of a stable supply and the avoidance of exposure
to metal price fluctuations. The price of copper purchased by the Company is
based on fluctuating market prices, usually with the COMEX price as a
benchmark. The Company generally has an "open pricing" option under which the
Company may set the price of all or a portion of the metal subject to a
purchase contract at any time up to the last COMEX trading day (usually two
days before the end of the month) of the last month in the contract period.


In the majority of cases, the price to the customer contains two components:
(i) a metal charge based on the market value of the metal content on the date
of shipment of the product to the customer; and (ii) a fixed fabrication
charge. In other cases, the Company quotes a firm price to the customer which
covers both the metal price and the fabrication charge. In either case, the
Company minimizes its exposure to metal price fluctuations through various
strategies. Generally, at the time the metal price for the customer is
established, the Company prices an equivalent amount of metal under its open
pricing arrangements with its suppliers. It is the Company's policy not to
attempt to profit from fluctuations in copper prices by taking commodity risks
or speculative commodity positions.

RESEARCH AND DEVELOPMENT

The Company's research and development efforts are devoted to new product
development and manufacturing process improvements. To further support the
Company's advancements in product and process development, the Company recently
completed construction of the 21,000 square foot Technology Center in Decatur,
Alabama. The Technology Center supports the engineering and testing of
specialized products and enhancement of the Company's custom-engineering
processes through which the Company customizes products to the particular
specifications of its customers. The Company's research and development is
conducted primarily at the Technology Center.

Heat transfer products, including the Company's line of "Turbo" products,
accounted for over 30% of commercial product gross profit in 1998. Turbo
products include Turbo-A, the Company's internally enhanced tube, Turbo-B and
Turbo-C, the proprietary line of enhanced surface boiling and condenser tube
for chillers. Demand for enhanced tube products is driven by the need for
improved energy efficiency. New product development will continue to be
concentrated in the heat transfer area. The Company is involved in several
industry, university and government sponsored research projects relating to
CFC-alternative refrigerants as well as more energy efficient tube for the
power and petrochemical industries. The ARI has chosen the Company's tube as
the "standard" to measure the efficiency of alternative refrigerants. See
"Phaseout of CFCs."

The Company's research and development expense was $1.5 million, $1.4 million
and $1.6 million for the years ended December 31, 1998, 1997 and 1996,
respectively. The Company uses its extensive manufacturing facilities and
personnel to assist in manufacturing process research and development efforts.
In addition, the Company engages in new product development efforts with
certain of its major customers.

ENVIRONMENTAL MATTERS

The Company's facilities and operations are subject to extensive environmental
regulations imposed by federal, state, provincial and local authorities in the
United States and Canada with respect to emissions to air, discharges to
waterways, and the generation, handling, storage, transportation, treatment and
disposal of waste materials. In addition, the Company has incurred, and in the
future may incur, liability under environmental statutes and regulations with
respect to the contamination of sites owned or operated by the Company
(including contamination caused by prior owners and operators of such sites)
and the off-site disposal of hazardous substances.

The Company believes its operations are in substantial compliance with the
terms of all applicable environmental laws and regulations as currently
interpreted. However, the Company expects that future regulations and changes
in the text or interpretation of existing regulations may subject the Company's
operations to increasingly stringent standards. While the precise effect of
these changes on the Company cannot be estimated, compliance with such
requirements may make it necessary, at costs which may be substantial, to
retrofit existing facilities with additional pollution-control equipment and to
undertake new measures in connection with the storage, transportation,
treatment and disposal of by-products and wastes.


                                       8
<PAGE>   11


The Company has a reserve of $3.0 million for environmental remediation costs.
This reserve is reflected in the Company's December 31, 1998 Consolidated
Balance Sheet and does not anticipate any recovery for amounts indemnified by
other parties. The total cost of environmental assessment and remediation
depends on a variety of regulatory, technical and factual issues, some of which
cannot be anticipated. While the Company believes that the reserve, under
existing laws and regulations, is adequate to cover presently identified
environmental remediation liabilities, there can be no assurance that such
amount will be adequate to cover the ultimate costs of these liabilities, or
the costs of environmental remediation liabilities that may be identified in
the future. See "Item 3--Legal Proceedings" and "Item 7--Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Environmental."

EMPLOYEES

As of December 31, 1998, the Company had a total of 3,316 employees. None of the
United States or the London, Ontario employees are represented by a union. A
majority of the hourly employees at the Montreal and Fergus plants are unionized
and are covered by collective bargaining agreements that expire in 1999. As a
whole, the Company believes its relations with its employees are good.

PATENTS AND TRADEMARKS

The Company owns a number of patents (in the United States and other
jurisdictions) on its products and related manufacturing processes, as well as
trademarks, and has granted licenses with respect to some of such patents and
trademarks. While the Company believes that its patents and trademarks have
competitive value, it does not consider the Company's success as a whole to be
dependent on its patents, patent rights or trademarks.

         associated with an acquisition that was not completed; and $0.7
         million of costs for discontinuing Poland operations of Small Tube
         Manufacturing Corporation (a wholly-owned subsidiary of the Company).

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

GENERAL

The following general factors should be considered in analyzing the Company's
results of operations:

COMPONENTS OF COST OF GOODS SOLD

A substantial portion of the Company's cost of goods sold reflects the cost of
raw material, principally copper. These costs, which fluctuate with the markets
for such raw material, are generally passed along to the Company's customers.
Accordingly, the levels of the Company's net sales and costs of goods sold are
affected by the rise and fall of copper prices, even in the absence of
increases or decreases in business activity. Such increases or decreases cause
variations in the Company's gross margin (gross profit as a percentage of net
sales), but have little direct impact on the Company's levels of gross profit.

VARIABILITY OF WHOLESALE PRODUCT GROSS PROFIT

Gross profit attributable to sales of the Company's wholesale products has
fluctuated and may continue to fluctuate substantially from period to period.
In 1998, 1997 and 1996, gross profit from sales of these products was $6.4
million, $2.8 million, and $7.9 million, respectively. Gross profit derived
from the sale of wholesale products is mainly affected by changes in selling
prices. Selling prices for these products are affected by general economic
conditions (especially the rate of housing starts), industry competition and
manufacturing capacity, industry production levels and other market factors,
all of which are beyond the control of the Company.

IMPACT OF PRODUCT MIX

The Company's products range from higher value-added and higher margin
commercial products to commodity-type products such as wholesale tube products
and rod, bar and strip products. The Company's overall profitability from
period to period is affected by the mix in sales within these categories. The
Company has substantial sales in Canada, and its product mix in that market, as
compared to the United States market, reflects a much higher percentage of
commodity type products, such as wholesale tube and rod, bar and strip
products. The results of Canadian operations reflect both this different
product mix and the impact of Canadian market and economic trends, which can be
independent of United States trends.

CYCLICAL AND SEASONAL NATURE OF DEMAND

Because the Company primarily supplies component parts, the Company's
operations are affected by changes in its customers' markets. Demand in certain
industries to which the Company sells its products is cyclical. In particular,
sales of plumbing tube and refrigeration service tube are affected by changes
in residential construction rates. Demand in certain industries to which the
Company sells, including the residential air conditioning industry, is also


                                      19
<PAGE>   22


seasonal. Sales to the residential air conditioning market are generally
greater in the first and second quarters of the year and lower in the third and
fourth quarters because manufacturers typically increase inventories in the
early part of the year in anticipation of summer air conditioning sales and
housing starts. In addition, sales of industrial tube are affected adversely in
years with unusually cool summers.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998, COMPARED WITH YEAR ENDED DECEMBER 31, 1997

Consolidated net sales for the year ended December 31, 1998 were $617.5 million,
a decrease of 7.5% from net sales of $667.7 million in 1997. Pounds shipped
increased by 5.4% in 1998 to 357.5 million from 339.3 million in 1997. Net sales
reflect a decrease in the price of copper, the Company's main raw material. The
average COMEX copper price for 1998 was $0.75 per pound, compared with $1.04 per
pound in 1997.

Shipments of commercial tube products increased 4.1% in 1998 over 1997,
primarily as a result of increased shipments of industrial tube used in the
residential air conditioning industry. The increase in shipments of industrial
tube was offset somewhat by reduced shipments of technical tube products.
Technical tube shipments decreased over prior period levels as the Company
experienced lower than anticipated demand for these products from major
customers, especially those customers with significant international sales.
Shipments of the Company's wholesale products increased 4.5% as a result of
increased participation by the Company in the United States market. Rod, bar
and strip product shipments increased 11.8% as compared to a year ago,
primarily as a result of increased shipments of strip products to the Canadian
mint. The Company expects that the continued international economic weakness,
particularly in Asia, will continue to affect the demand for technical tube in
1999. Pounds shipped in the United States were 227.8 million in 1998,
representing an increase of 1.5% over 1997. Pounds shipped in Canada in 1998
were 129.7 million, a 12.3% increase over 1997.

Consolidated gross profit increased 0.1% in 1998 to $82.7 million from $82.6
million in 1997. Excluding the effect of the $2.1 million non-recurring charge,
consolidated gross profit was $84.8 million in 1998. This charge includes $1.4
million of costs associated with the closing of the Company's Greenville,
Mississippi facility and $0.7 million of costs associated with efficiency
initiatives being implemented at the Company's Roxboro, North Carolina
facility. Gross profit from United States operations decreased by 5.9% to $65.5
million from $69.6 million in 1997 due to the factors outlined above. Gross
profit from Canadian operations increased by 32.3% to $17.2 million from $13.0
million in 1997, principally due to the factors outlined above.

Consolidated selling, general and administrative expenses for the year ended
December 31, 1998 increased 15.4% to $25.5 million, compared with $22.1 million
in 1997. This increase was primarily the result of increased employee benefits,
marketing expenses and professional fees.


During the year ended December 31, 1998, the Company recognized a non-recurring,
pre-tax charge ("the 1998 non-recurring charge") of approximately $11.9 million
($7.5 million after tax). This charge included $7.4 million in expenses related
to the closing of the Company's Greenville, Mississippi facility, of which $5.6
million of


                                      20
<PAGE>   23


expenses related to the write-off of impaired assets resulting primarily from
the closing of this facility; $2.7 million in expenses related to efficiency
initiatives being implemented at the Company's North Carolina facility; $0.9
million in expenses related to the implementation of a salaried workforce
reduction program; and $0.9 million in professional fees and other costs
primarily associated with an acquisition that was not completed. As the
Greenville, Mississippi facility is no longer operational, the net assets of
this facility, which is being held for sale, have been recorded at their
estimated net realizable value.

During the year ended December 31, 1997, the Company recognized a non-recurring
pre-tax charge ("the 1997 non-recurring charge") to operations of approximately
$4.4 million ($3.0 million after tax). This one-time charge to operations
included $1.8 million of expenses related to the implementation of the Company's
1997 Voluntary Early Retirement Program; $1.3 million in severance costs
primarily associated with the departure of the Company's former Chief Executive
Officer; $0.6 million in professional fees and other costs associated with an
acquisition that was not completed; and $0.7 million in costs for discontinuing
the Poland operations of Small Tube Manufacturing Corporation (a wholly-owned
subsidiary of the Company).

As a result of increased selling, general and administrative expenses and the
recognition of the 1998 non-recurring charge, consolidated income from
operations decreased by 19.2% to $45.4 million in 1998, from $56.2 million in
1997. Excluding the effect of the non-recurring charges in 1998, and the 1997
non-recurring charge in the prior year period, income from operations was $59.4
million in 1998 and $60.5 million in 1997. United States income from operations
decreased by 31.7% to $30.8 million in 1998 from $45.1 million in 1997, and
Canadian income from operations increased by 31.5% to $14.6 million in 1998 from
$11.1 million in 1997.

Consolidated net interest expense decreased by 10.9% to $6.6 million in 1998
from $7.4 million in 1997. This decrease was primarily the result of reduced
interest expense achieved through the Company's April 1997 refinancing and the
related repayment of its 10 1/8% Senior Subordinated Notes due 2002 (the "10
1/8% Notes"), increased interest income from investing the remaining proceeds
from the issuance of $150 million in principal amount of 7 3/8% Senior Notes
due 2008 in August 1998 (the "Senior Notes") and increased capitalized interest
associated with several capital projects in 1998. This decrease was partially
offset by increased interest expense associated with the Company's Senior
Notes. The Company incurred an extraordinary charge associated with the early
extinguishment of the 10 1/8% Notes. The charge on the extinguishment, net of
tax, was approximately $4.7 million ($7.5 million pre-tax).

The effective tax rate for the year ended December 31, 1998 was 35.2%, compared
to 36.4% for the year ended December 31, 1997. The reduced effective tax rate in
1998 was the result of the Company recognizing a tax benefit associated with the
non-recurring charges in 1998. Excluding the effect of the tax benefit
associated with the non-recurring charges in 1998, the effective tax rate would
have been 35.7% in 1998.


Excluding the non-recurring charges in the current year period and the 1997
non-recurring charge and the extraordinary item in the prior year period,
consolidated net income and diluted earnings per share for 1998 would have been
$33.5 million and $2.34, respectively, compared to $33.6 million and $2.34,
respectively, in the prior year period. Consolidated net income in 1998 was


                                      21
<PAGE>   24


$24.6 million, or $1.72 per diluted share, compared to $25.8 million or $1.80
per diluted share in 1997.


YEAR ENDED DECEMBER 31, 1997, COMPARED WITH YEAR ENDED DECEMBER 31, 1996

Consolidated net sales for the year ended December 31, 1997, were $667.7
million, a decrease of 4.6% from net sales of $699.9 million in 1996. Pounds
shipped decreased by 2.9% in 1997 to 339.3 million from 349.3 million in 1996.
The decrease in net sales reflects a decrease in the price of copper, the
Company's main raw material, and in pounds shipped. The average COMEX copper
price for 1997 was $1.04 per pound, compared with $1.06 per pound in 1996. Net
sales were also impacted by a decrease in fabrication charges to customers for
wholesale and rod, bar and strip products which were offset by increased
fabrication charges in the commercial product line.

Shipments of commercial tube decreased 5.8% in 1997 from 1996, primarily as a
result of decreased shipments of industrial tube used in the residential air
conditioning industry, as well as a 3.4% decrease in technical tube shipments.
The decrease in shipments of industrial tube was principally attributable to a
decline in orders from customers in the residential air conditioning industry,
which generally did not meet its anticipated levels of production for 1997, and
the decrease in technical tube shipments was primarily because the
manufacturers of large commercial air conditioners reduced their production
from the previous years' levels. The decline in commercial shipments was offset
somewhat by a 10.8% increase in shipments of fabricated products, primarily
resulting from the acquisition of Tube Forming, Inc. in September 1996.
Shipments of the Company's wholesale products increased 5.8% as a result of
increased participation by the Company in the United States market. Rod, bar
and strip product shipments decreased 2.3%, primarily as a result of a decline
in shipments of strip products. Pounds shipped in the United States were 223.9
million in 1997, representing an increase of 4.8% from 1996. Canadian pounds
shipped in 1997 were 115.4 million, 14.9% less than 1996.

Consolidated gross profit decreased 11.8% for 1997 to $82.6 million from $93.7
million in 1996. This decline was primarily the result of the decreased
shipments of commercial products, which are generally the Company's highest
margin products, and a shift in product mix within the commercial product
category. In addition, the fabrication price charged to customers for the
Company's wholesale products decreased 24.8%, which resulted in decreased gross
profit. Consolidated gross margin decreased to 12.4% in 1997, from 13.4% in
1996.

Gross profit from United States operations decreased by 7.9% to $69.9 million,
from $75.6 million in 1996, due to the factors outlined above. Gross profit
from the Canadian operations decreased by 28.2% to $13.0 million from $18.1
million in 1996, principally due to decreased wholesale product fabrication
charges and reduced pounds shipped.

Consolidated selling, general and administrative expenses for the year ended
December 31, 1997 were $22.1 million, compared with $21.9 million in 1996.

During the year ended December 31, 1997, the Company recognized the pre-tax 1997
non-recurring charge to operations of approximately $4.4 million ($3.0 million
after tax). This one-time charge to operations included $1.8 million of expenses
related to the


                                      22
<PAGE>   25


implementation of the Company's 1997 Voluntary Early Retirement Program; $1.3
million of severance costs primarily associated with the departure of the
Company's former Chief Executive Officer; $0.6 million of professional fees and
other costs associated with an acquisition that was not completed; and $0.7
million of costs for discontinuing the Poland operations of Small Tube
Manufacturing Corporation (a wholly-owned subsidiary of the Company).

As a result of decreased gross profit, slightly increased selling, general and
administrative expenses and the recognition of the 1997 non-recurring charge,
consolidated income from operations decreased by 21.7% to $56.2 million in 1997,
from $71.8 million in 1996. United States income from operations decreased by
21.3% to $45.1 million, from $57.3 million, and Canadian income from operations
decreased by 23.4% to $11.1 million in 1997, from $14.5 million in 1996.

Consolidated net interest expense decreased by 20.4% to $7.4 million in 1997
from $9.3 million in 1996. This decrease is primarily due to reduced interest
expense resulting from the Company's refinancing of debt outstanding under its
10 1/8% Notes in April 1997, but was partially offset by reduced interest income
resulting from a reduced amount of cash holdings during 1997 as a result of the
Company's use of cash to purchase Tube Forming, Inc. in the third quarter of
1996. During the year ended December 31, 1997, the Company incurred an
extraordinary charge associated with the early extinguishment of the 10 1/8%
Notes for unamortized debt issuance cost, professional fees and prepayment
premium. The charge on the extinguishment net of tax was approximately $4.7
million ($7.5 million pre-tax).

The effective tax rate for the year ended December 31, 1997 was 36.4%, compared
to 35.5% for the year ended December 31, 1996. Upon an evaluation of the
Company's income tax position during the period ended December 31, 1996, the
tax provision was reduced to reflect the settlement of certain tax issues.

For the year ended December 31, 1997, net income was $25.8 million, or $1.80
per diluted share, compared with $39.6 million, or $2.77 per diluted share, for
the year ended December 31, 1996. Excluding the non-recurring charge and the
extraordinary charge relating to the extinguishment of the 10 1/8% Notes, net
income was $33.6 million or $2.34 per diluted share, for the year ended
December 31, 1997.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities is the Company's primary source of
liquidity and totaled $35.8 million, $46.7 million and $39.4 million for the
years ended December 31, 1998, 1997 and 1996, respectively. The decrease in 1998
from 1997 was primarily due to decreased net income, net of non-recurring
charges and increased inventories. The decrease in accounts receivable from
December 31, 1998 to 1997 is primarily due to decreased sales activity and
reduced COMEX copper prices over the prevailing prices at year end 1997.

The ratio of current assets to current liabilities was 4.7 in 1998 and 3.5 in
1997. The current ratio increased in 1998 over 1997 primarily as a result of
increased cash and equivalents resulting from the issuance of the Senior Notes
in 1998, and increased inventories resulting from, among other things, the
addition of the Shanghai, China and Jackson, Tennessee facilities.


                                      23
<PAGE>   26

In June 1998, the Company amended certain provisions of the Company's $200
million Revolving Credit Facility (the "Facility"), which included (i)
increasing the amount of unsecured indebtedness that the Company may incur
while borrowings under the Facility are outstanding, (ii) waiving the
requirement that the proceeds of the Senior Notes must be used to repay all the
outstanding borrowings under the Facility, and (iii) raising the ratio of total
debt to EBITDA permitted while borrowings are outstanding under the Facility.
The Facility, as amended, matures in full on April 30, 2002, and currently
provides for a floating base interest rate that is, at the Company's election,
either (a) the higher of the federal funds effective rate plus 0.50% and the
prime rate or (b) LIBOR plus a specified margin (determined with reference to
the Company's ratio of total debt to EBITDA and the Company's debt rating as
determined by the Standard & Poor's and Moody's Rating Services) of 0.25% to
1.00%. Commitment fees on the unused available portion of the Facility range
from 0.10% to 0.50%. As of December 31, 1998, the Company had approximately $67
million in outstanding borrowings and obligations under the Facility and
approximately $133 million in additional borrowing availability thereunder.

In May 1998, the Company acquired a facility located in Jackson, Tennessee, and
the related welded tube manufacturing equipment and technology, from a
subsidiary of Korea-based Poongsan Corporation. The equipment at this facility
is being installed and tested, and commercial production began in January 1999.
The aggregate purchase price was approximately $35.4 million, and was financed
in part from borrowings under the facility.

During the third quarter of 1998, the Company implemented a work force reduction
program of approximately fifty salaried positions from various locations and
departments, which was primarily aimed at reducing administrative costs. Each
terminated employee's severance pay was, in general, calculated in accordance
with a Severance Pay Plan (the "Severance Plan"), which provides benefits to all
eligible employees who have at least one year of service and who are terminated
for reasons other than cause. Severance benefits include payment of all accrued
vacations and two weeks' pay at the employee's current base salary plus one
week's pay for each full year of continuous service, not to exceed 26 weeks.
Acceptance of severance benefits constitutes a release of all claims against the
Company, except claims in accordance with the provisions of applicable benefit
plans. The Company expects to realize approximately $2.0 million in reduced
salary and related expenses per year as a result of this workforce reduction.
Implementation of the workforce reduction program resulted in an approximate
$0.9 million charge that was included in the Company's 1998 non-recurring charge
and recognized in the third quarter of 1998. The primary components of the
charge relating to the work force reduction program included approximately $0.8
million relating to severance and vacation pay and $0.1 million related to
professional fees and miscellaneous expenses resulting from the workforce
reductions.

During the third quarter of 1998, the Company implemented plans to close the
Greenville, Mississippi fabricated products facility. Customers of this
facility will be served by the Company's Ardmore, Tennessee, Altoona,
Pennsylvania, or Carrollton, Texas facilities. The closing of this facility was
completed in early November 1998, and the approximately 140 employees received
severance pay in accordance with the Severance Plan and also received their
regular pay for 60 days subsequent to the notice of closure. The Company
expects to realize approximately $2.5 million in reduced salary and related
expenses per year as a result of the 


                                      24
<PAGE>   27

closure of this facility. Implementation of the plan to close this facility has
resulted in an approximate $8.8 million charge, of which $7.4 million is
included in non-recurring and other charges and $1.4 million is included in
cost of goods sold. Primary components of the charge relating to closing the
Greenville facility included $5.6 million related to the write down of impaired
fixed assets, $1.6 million primarily related to severance costs and $1.5
million primarily related to other asset write downs and operating
inefficiencies resulting from the closure of this facility.

In the first quarter of 1997, the Company adopted the 1997 Voluntary Early
Retirement Program (the "Plan"). This Plan rewards certain eligible employees
who elected on a voluntary basis to take early retirement from the Company
between March 26, 1997, and May 12, 1997. After the execution of a binding
Voluntary Early Retirement Agreement and General Release by each eligible
employee, the Company paid each such employee an early retirement payment and
provided certain other consideration. The payment was an amount equal to four
weeks' base pay plus one additional weeks' pay for each year of service, up to a
maximum of twenty-six weeks total pay, less applicable taxes and withholdings
required by law. Twenty-six employees from various locations and departments
throughout the Company elected to participate in the Plan. At the end of the
second quarter of 1997, the implementation of the Plan was completed. The
Company expects to realize approximately $2.0 million in reduced salary and
related expenses per year as a result of the Plan. Implementation of the Plan
resulted in an approximate $1.8 million charge that was included in the
Company's 1997 non-recurring charge and was recognized in the second quarter of
1997. The primary components of the charge relating to the Plan include
approximately $1.0 million relating to severance and vacation pay, $0.6 million
in increased pension expense and $0.2 million for professional fees and
miscellaneous expenses resulting from these early retirements.

In the ordinary course of business, the Company enters into various types of
transactions that involve contracts and financial instruments with off-balance
sheet risk. The Company enters into these financial instruments to manage
financial market risk, including foreign exchange risk, commodity price risk
for certain customers and interest rate risk. The Company is exposed to loss on
the forward contracts in the event of non-performance by the customer whose
orders are covered by such contracts. However, the Company does not anticipate
non-performance by such customers. The Company accounts for its interest rate
swap as a hedge; accordingly, gains and losses are recognized as interest
expense. The Company enters into these financial instruments utilizing
over-the-counter, as opposed to exchange-traded, instruments. The Company
attempts to mitigate the risk that counter parties to these over-the-counter
agreements will fail to perform by only entering into agreements with major
international financial institutions.

Capital expenditures were $34.7 million in 1998, $21.6 million in 1997 and $8.5
million in 1996. The Company currently expects to spend approximately $27
million in 1999 under its capital improvement program. The Company's 1999
capital improvement program includes asset replacement, environmental
compliance and asset improvement items. The Company believes that it will be
able to satisfy its existing working capital needs, interest obligations and
capital expenditure requirements with cash flow from operations and funds
available under the Facility.

SENIOR NOTES DUE 2008

In August 1998, the Company issued $150 million in principal amount of the
Senior Notes. The Senior Notes were issued pursuant to an Indenture, dated as of
August 4, 1998, between the Company and First Union National Bank, as Trustee.
The net proceeds from the sale of the Senior Notes were applied to reduce
borrowings by approximately $58 million under the Facility. Of the remaining net
proceeds, the Company intends to use the remainder for capital expenditures and
potential future acquisitions, working capital and other general corporate
purposes. Pending such uses, the Company will invest such proceeds in short-term
interest-bearing securities. The Senior Notes (i) have interest payments dates
on February 1 and August 1 of each year, commencing February 1, 1999; (ii) are
redeemable at the option of the Company at a redemption price equal to the
greater of (a) 100% of the principal amount of the Senior Notes to be redeemed,
or (b) the sum of the present value of the remaining scheduled payments of
principal and interest thereon from the redemption date to the maturity date,
discounted to the redemption date on a semiannual basis at the Treasury Rate
plus 25 basis points, plus, in each case, accrued interest thereon to the date
of redemption; (iii) are senior unsecured obligations of the Company and are
pari passu in right of payment with any existing and future senior unsecured
indebtedness of the Company, including borrowings under the Facility; (iv) are
guaranteed by certain of the Company's subsidiaries; and (v) are subject to the
terms of the Indenture, which contains certain covenants that limit the
Company's ability to incur indebtedness secured by certain liens and to engage
in sale/leaseback transactions.


IMPACT OF YEAR 2000

The Company utilizes a number of computer software programs and operating
systems throughout its organization, including applications used in order
processing, shipping and receiving, accounts payable and receivable processing,
financial reporting and in various other administrative functions. The Company
recognizes the need to ensure that its operations will not be adversely
impacted by applications and processing issues related to the upcoming calendar
year 2000 (the "Year 2000 Issue"). The Year 2000 Issue is the result of
computer programs that have been written to recognize two digit, rather than
four digit, date codes to define the applicable year. To the extent that the
Company's software applications contain source codes that are unable to
appropriately interpret a code using "00" as the upcoming year 2000 rather than
1900, the Company could experience system failures or miscalculations that
could disrupt operations and cause a temporary inability to process
transactions, send and process invoices or engage in similar normal business
activities.

Based on a recent assessment of its systems, the Company has determined that it
will be required to modify or replace significant portions of its software so
that its computer systems will function properly with respect to dates in the
year 2000 and thereafter. The Company presently believes that with
modifications to its existing software and certain conversions to new software,
the Year 2000 Issue will not pose significant operational problems for its
computer systems. In addition, the Company's systems and operations are
dependent, in part, on interaction with systems operated or provided by vendors
or other third-parties, and the Company is currently surveying those parties
about their progress in identifying and addressing problems that their computer
systems may face in connection with the Year 2000 Issue. The Company believes
that it has no exposure for contingencies related to Year 2000 Issue for the
products it has sold.


                                      26
<PAGE>   29


The Company's plan to address the Year 2000 Issue (the "Plan") identifies
exposure in three areas: information technology, operating equipment with
embedded chips or software, and third-party vendors. In addition, the Plan
involves the following four phases for each of the exposure areas: assessment,
remediation, testing and implementation. With respect to information technology,
the Company has fully completed its assessment of this area. This assessment
indicated that most of the Company's significant information technology systems
could be affected, particularly the general ledger, billing, payables and
inventory systems. To date, the Company is 92% complete on the remediation phase
for the information technology area and expects to complete software
reprogramming and replacement no later than June 30, 1999. Once software is
reprogrammed or replaced, the Company will begin testing and implementation.
These phases run concurrently for multiple systems. To date the Company has
completed 55% of its testing and has implemented 50% of its remediation systems.
Completion of the testing phase for all significant systems is expected by
September 30, 1999, with all remediation and implementation of systems expected
to be fully tested and operational by October 1, 1999.

The Company is beginning the assessment and remediation phases for its
operating equipment with embedded chips or software. As the assessment phase
continues, the Company will begin to develop and implement any necessary
remediation efforts with the manufacturers or servicers of the operating
equipment. The target for completion of the remediation phase is March 31,
1999. Testing and implementation of affected equipment is expected to be
complete by June 30, 1999.

The assessment of third-party vendors and customers and their exposure to the
Year 2000 Issue is 100% complete for systems that directly interface with the
Company and 80% complete for all other material exposure. The Company expects to
complete surveying of all third-parties by May 1999, has completed remediation
efforts on these systems and is 80% complete with the testing and implementation
phases. The testing phase of the systems interface work is expected to be
complete by April 30, 1999. The Company has queried its significant suppliers
that do not share any information systems with the Company ("external agents").
To date, the Company is not aware of any external agent with a Year 2000 Issue
that would materially impact the Company's results of operations, liquidity or
capital resources. The Company, however, has no means of ensuring that external
agents will be Year 2000 compliant. The inability of external agents to complete
their Year 2000 resolution processing in a timely fashion could materially
impact the Company. The effect of non-compliance by external agents is not
determinable by the Company.

The Company is utilizing both internal and external resources to reprogram, or
replace, and test its software for Year 2000 modifications. The total cost of
the Year 2000 project is estimated at $5.5 million and is being funded through
operating cash flows. Of the total project cost, approximately $5.3 million is
attributable to the purchase of new software, which will be capitalized. The
remaining $0.2 million, which will be expensed as incurred, is not expected to
have a material effect on the results of operations. To date, the Company has
incurred approximately $4.3 million in costs related to the assessment,
remediation and implementation efforts in its Year 2000 modification project,
the development of the plan for the purchase of new systems and systems
modifications. The Company has engaged an independent outside consultant (the
"Consultant") to review the adequacy, completeness and feasibility of the Plan.
The Consultant has made recommendations that the Company is currently
considering regarding 


                                      27
<PAGE>   30


improvements to the Plan. After the Company completes the review and responds
to these recommendations, the Consultant will review the Company's responses to
these recommendations and will continue to monitor the Company's execution of
the Plan. The Company currently has no contingency plans in place in the event
that it does not complete all phases of the Year 2000 remediation program. The
Company plans to evaluate the status of completion in April 1999 and develop 
contingency planning.

The costs of the project and the timeframe in which the Company believes it
will complete the Year 2000 modifications are based on management's best
estimates, which were derived utilizing numerous assumptions of future events,
including the continued availability of certain resources, third-party
modification plans and other factors. Specific factors that might result in
additional costs or time delays include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer codes and similar uncertainties. Based on the
Company's current estimates, the Company does not anticipate that the cost of
compliance with the Year 2000 Issue will be material to its business, financial
condition or results of operations; however, there can be no assurance that the
Company's systems, or those of its vendors, customers or other third-parties,
will be made Year 2000 compliant in a timely manner or that the impact of the
failure to achieve such compliance will not have a material adverse effect on
the Company's business, financial condition or results of operations.

ENVIRONMENTAL

The Company's facilities and operations are subject to extensive environmental
laws and regulations. During the year ended December 31, 1998, the Company
spent approximately $0.3 million on environmental matters, which include
remediation costs, monitoring costs and legal and other costs. The Company has
a reserve of $3.0 million for environmental remediation costs which is
reflected in the Company's Consolidated Balance Sheet. The Company has approved
and spent $0.4 million for capital expenditures relating to environmental
matters during 1998. Based upon information currently available, the Company
believes that the costs of the environmental matters described below are not
reasonably likely to have a material adverse effect on the Company's business,
financial condition or results of operations.

OKLAHOMA CITY, OKLAHOMA

The Company is one of a number of Potentially Responsible Parties ("PRPs")
named by the United States Environmental Protection Agency (the "EPA") with
respect to the soil and groundwater contamination at the Double Eagle Refinery
Superfund site in Oklahoma City, Oklahoma. The costs associated with the
cleanup of this site will be entirely borne by the PRP group (the "Group"), as
the site owner has filed for bankruptcy protection. In March 1993, twenty-three
PRPs named with respect to the soil contamination of the site, including the
Company, submitted a settlement offer to the EPA. Settlement negotiations
between the Group and the EPA are continuing, and a settlement and consent
order is currently being contemplated among the PRPs, the EPA and the State of
Oklahoma which would provide for each PRPs liability to be limited to a prorata
share of an aggregate amount based on the EPA's worst-case cost scenario to
remediate the site. Under the current proposal the Company's settlement amount
is estimated to be $390,000.


                                      28
<PAGE>   31


DECATUR, ALABAMA

The Company is subject to an order under Section 3008(h) of the Resource
Conservation and Recovery Act ("RCRA") to perform a facilities investigation of
its site in Decatur, Alabama, including a portion of the site where wastes were
buried (the "Burial Site"). Should the EPA decide to order remediation, the
remaining monitoring, legal and other costs are estimated to be $1.0 million.
The Company is currently awaiting comments and approval from the EPA on a
Corrective Measures Study ("CMS") that Henley had submitted to the EPA
regarding the Burial Site. The cost to the Company to comply with the CMS, as
currently presented, will not have an adverse effect on the Company's business,
financial condition or results of operations.

ARDMORE, TENNESSEE

On December 28, 1995, the Company entered into a Consent Order and Agreement
with the Tennessee Division of Superfund (the "Tennessee Division"), relating
to the Ardmore, Tennessee facility (the "Ardmore facility"), under which the
Company agreed to conduct a preliminary investigation regarding whether
volatile organics detected in and near the municipal drinking water supply are
related to the Ardmore facility and, if necessary, to undertake an appropriate
response. That investigation has disclosed contamination, including elevated
concentrations of certain volatile organic compounds, in soils of certain areas
of the Ardmore facility and also has disclosed elevated levels of certain
volatile organic compounds in the shallow residuum groundwater zone at the
Ardmore facility. Under the terms of the Consent Order and Agreement, the
Company submitted a Remedial Investigation and Feasibility Study ("RI/FS") work
plan, which was accepted by the Tennessee Division, and the Company has
initiated the RI/FS. Based on the available information, the Company
preliminarily estimates that it will cost between $374,000 and $1,174,000 to
complete the investigation and remediation of this site.

A recent report of a 1995 EPA site inspection of the Ardmore facility
recommended further action for the site. The Company believes, however, that
because the Tennessee Division is actively supervising an ongoing investigation
of the Ardmore facility, it is unlikely that the EPA will intervene and take
additional action. If the EPA should intervene, however, the Company could
incur additional costs for any further investigation or remedial action
required.

GREENVILLE, MISSISSIPPI

Following the Company's acquisition of its Greenville, Mississippi facility
(the "Greenville facility"), a preliminary investigation disclosed volatile
organic contaminants in soil and groundwater at the site. Based on further
investigation, it appears that the contamination has not spread off-site. The
Company entered into a Consent Order with the Mississippi Department of
Environmental Quality ("MDEQ") for a pilot study program which will help
determine the effectiveness of certain technology tentatively identified for
remediation, which will also help define the scope of remediation for the site.
The pilot study program concluded on June 1, 1997. The Company entered into a
final consent agreement with MDEQ on July 15, 1997. Remediation efforts began
in the third quarter of 1997 and are expected to continue for approximately
three years. However, there can be no assurance that remediation efforts will
be allowed to be discontinued after three years, and operations, maintenance
and other expenses of 


                                      29
<PAGE>   32


the remediation system may continue for a longer period of time. Through
October 3, 1998, applicable costs of testing and remediation required at the
Greenville facility have been shared with the former owners of the Greenville
facility pursuant to the terms of an Escrow Agreement established at the time
the facility was acquired. Subsequent to October 3, 1998, the Company released
the former owners of the facility from liability related to the remediation of
the Greenville facility following the receipt of a $145,000 settlement payment.
The Company estimates the remaining investigative and remedial costs could
total $431,000 under the remediation plant the Company adopted, but these costs
could increase if additional remediation is required.

JACKSON, TENNESSEE

In connection with the Company's acquisition of its Jackson, Tennessee facility
(the "Jackson facility"), a preliminary investigation disclosed soil and/or
groundwater contamination at this site. The Company has performed a Phase I
Environmental Audit and identified the existence of volatile organic
contaminants; however, the extent of any such contamination has not been fully
determined. Investigation at the site is being conducted pursuant to a consent
order with the State of Tennessee by a prior owner of the property. Based upon
currently available information, the Company preliminarily estimates that
remediation costs could total $750,000. Certain of the remediation costs,
however, may be reimbursed pursuant to the terms of an indemnification
agreement between the Company and the previous owners of the Jackson Facility.

OTHER

The Company has been identified by the EPA as one of a number of PRPs at
Superfund sites in Athens, Alabama and in Criner, Oklahoma. The Company
believes that its potential liability with respect to these Superfund sites is
not material. There can be no assurance, however, that the Company will not be
named a PRP at additional Superfund sites in the future, or that the costs
associated with any such sites would not be substantial.

The Company believes that it faces no significant liability for the Athens,
Alabama site because it has removed all of the material it contributed to the
site. The Company believes that it faces no significant liability for the
Criner, Oklahoma site because Henley, the prior owner of the site, has retained
liability for all cleanup costs resulting from past disposal of used oil at the
Criner, Oklahoma site pursuant to an indemnification agreement between the
Company and Henley. Henley, which is not affiliated with the Company, has
discharged these obligations to date.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board issued Statement No. 133
Accounting for Derivative Instruments and Hedging Activities. This statement
provides a comprehensive and consistent standard for the recognition and
measurement of derivatives and hedging activities. Statement No. 133 requires
all derivatives to be recorded on the balance sheet at fair value and
establishes special accounting for the following three different types of
hedges: changes in the fair value of assets and liabilities of firm
commitments; hedges of the variable cash flows of forecasted transactions; and
hedges of foreign currency exposures of net investments in foreign operations.
Though the accounting treatment and criteria for each of the 


                                      30
<PAGE>   33


three types of hedges is unique, they all result in recognizing offsetting
changes in value or cash flows of both the hedge and hedged item in earnings in
the same period. Changes in the fair value of derivatives that do not meet the
criteria of one of these three categories of hedges are included in earnings in
the period of the change. Statement No. 133 is effective for fiscal years
beginning after June 15, 1999, but early adoption is allowed. Adoption of this
statement is not expected to have a material effect on the Company's
consolidated financial statements.

In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, Reporting on the Costs of Start-Up Activities. This
Statement of Position provides guidance on the financial reporting of start-up
costs and organizational costs, and requires these costs to be expensed as
incurred. This Statement of Position applies to all non-governmental entities
and, in general, is effective for financial statements for fiscal years
beginning after December 15, 1998. Initial application of this Statement of
Position should be reported as the cumulative effect of a change in accounting
principle, and entities are not required to report the pro forma effects of
retroactive application. The Company will adopt this Statement of Position in
the first quarter of 1999 and will accordingly recognize a pre-tax expense of
approximately $6.0 to $8.0 million as a cumulative effect of the change in
principle.

WOLVERINE TUBE, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS

The accompanying consolidated financial statements include the accounts of
Wolverine Tube, Inc. (the "Company") and its wholly-owned subsidiaries. All
significant intercompany transactions and balances have been eliminated. 

The Company is engaged in the manufacturing and distribution of copper and
copper alloy tubular products as well as rod, bar and strip products. The
Company's focus is developing and manufacturing high value added products used
in engineered applications which require tubular products that have superior
heat transfer capability. The Company's major customers are primarily located in
North America and include the residential and commercial building industries,
plumbing wholesalers, air conditioning and refrigeration manufacturers,
utilities and automobile manufacturers, refining and chemical processing
companies and industrial manufacturers. Sales are made under normal terms and
generally do not require collateral.

CASH AND EQUIVALENTS

The Company considers all highly liquid financial instruments with a maturity of
three months or less at the time of purchase to be cash equivalents.

INVENTORIES

Inventories are stated at the lower of cost or market. Approximately 71% and 73%
of the total amounts of consolidated inventories at December 31, 1998 and 1997
are stated on the basis of last-in, first-out (LIFO) method. The remaining
inventories, which primarily include supplies, are valued using the average cost
method.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is stated at cost. Depreciation is provided on the
straight-line method over the following periods:

<TABLE>
        <S>                                            <C>      
        Furniture and fixtures                         2-9 years

        Tooling                                        3-10 years

        Building and improvements                      3-39 years

        Machinery and equipment                        5-25 years
</TABLE>

                                      F-5

<PAGE>   45
IMPAIRMENT OF LONG-LIVED ASSETS

Impairment losses are recorded on long-lived assets used in operations where
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by these assets are less than their carrying amount.

INCOME TAXES

Deferred income taxes are provided for the temporary differences between the
financial reporting basis and the tax basis of the Company's assets and
liabilities. Property, plant and equipment, inventories, prepaid pension,
postretirement benefit obligations and certain other accrued liabilities are the
primary sources of these temporary differences.

DEFERRED CHARGES AND INTANGIBLE ASSETS

Debt issuance costs are deferred and amortized over the term of the debt to
which they relate using the interest method. Intangible assets consist of
patents and goodwill. Patents are amortized on the straight-line method over
their estimated lives. Excess cost over the fair value of net assets acquired
(or goodwill) generally is amortized on a straight-line basis over 40 years. The
carrying value of goodwill is reviewed if the facts and circumstances suggest
that it may be impaired. Negative operating results, negative cash flows from
operations, among other factors, could be indicative of the impairment of
goodwill. If this review indicates that goodwill will not be recoverable, the
Company's carrying value of the goodwill would be reduced.

EARNINGS PER COMMON SHARE

Basic net income per share is based on the weighted average number of common
shares outstanding and net income reduced by preferred dividends. Diluted net
income per share is based on the weighted average number of common shares
outstanding plus the effect of dilutive employee stock options and net income
reduced by preferred dividends.

FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods are used by the Company in estimating fair value
disclosures for financial instruments: 

Cash and equivalents: the carrying amount reported in the consolidated balance
sheets for cash and equivalents approximates its fair value. 

Financing arrangement, long-term debt and redeemable cumulative preferred stock:
The carrying amount of the Company's borrowings under its financing arrangement
approximates its fair value. The fair value of the Company's long-term debt and
derivative financial instruments are based upon quoted market price. The fair
value of the Company's redeemable cumulative preferred stock is based upon its
dividend rate and call provisions. The fair value of the Company's long-term
debt and redeemable cumulative preferred stock was $143,880,000 and $2,215,000,
respectively, at December 31, 1998.

                                      F-6

ENVIRONMENTAL EXPENDITURES

Environmental expenditures that pertain to current operations and relate to
future revenues are expensed or capitalized consistent with the Company's
capitalization policy. Expenditures that result from the remediation of an
existing condition caused by past operations, that do not contribute to future
revenues, are expensed. Liabilities are recognized for remedial activities when
the cleanup is probable and the cost can be reasonably estimated.

MARKET RISK
The Company is exposed to various market risks, including interest rates,
foreign currency exchange rates and derivative commodity instruments. Market
risk is the potential loss arising from adverse changes in market rates and
prices. The Company does not enter into derivatives or other financial
instruments for trading or speculative purposes. The Company enters into
financial instruments to manage and reduce the impact of changes in interest
rates, foreign currency and commodity prices.

INTEREST RATE SWAPS

The Company enters into interest-rate swap agreements to modify the interest
characteristics of its outstanding debt. Each interest-rate swap agreement is
designated as a hedge with the principal balance and term of a specific debt
obligation. These agreements involve the exchange of amounts based on a fixed
interest rate for amounts based on variable interest rates over the life of the
agreement, without an exchange of the notional amount upon which the payments
are based. The differential to be paid as interest rates change is accrued and
recognized as an adjustment of interest expense related to the debt (the accrual
accounting method). The fair value of the swap agreements and changes in the
fair value as a result of changes in market interest rates are not recognized in
the financial statements. At December 31, 1998, the Company was a party to one
interest rate swap agreement. The estimated fair value of this interest rate
swap was a net payable of $3.2 million at December 31, 1998. A 1% decrease in
the 30-day LIBOR rate would increase the amount paid to approximately $5.2
million.

Gains and losses on terminations of interest-rate swap agreements are deferred
as an adjustment to the carrying amount of the outstanding debt and amortized as
an adjustment to interest expense related to the debt over the remaining term of
the original contract life of the terminated swap agreement. In the event of the
early extinguishment of a designated debt obligation, any realized or unrealized
gain or loss from the swap would be recognized in income coincident with the
extinguishment gain or loss. The Company mitigates the risk that counter parties
to these over-the-counter agreements will fail to perform by only entering into
agreements with major international financial institutions.

FOREIGN CURRENCY FORWARDS

The Company sometimes uses foreign exchange contracts to reduce its exposure to
foreign currency risk associated with purchasing contracts denominated in
foreign currency. A forward foreign exchange contract obligates the Company to
exchange predetermined amounts of specified foreign currencies at specified
exchange rates on specified dates or to make an equivalent U.S. dollar payment
equal to the value of such exchange.


                                      F-7
<PAGE>   47

These contracts are designated and effective as hedges and discounts or premiums
(the difference between the spot exchange rate and the forward exchange rate at
inception of the contract) are accreted or amortized to other operating expenses
over the contract lives using the straight-line method while realized and
unrealized gains and losses resulting from changes in the spot exchange rate
(including those from open, matured, and terminated contracts), net of related
taxes, are included in the cumulative translation adjustment account in
stockholders' equity (the deferral accounting method). The Company mitigates the
risk that counter parties to these over-the-counter agreements will fail to
perform by only entering into agreements with major international financial
institutions. At December 31, 1998, the Company was not a party to any material
contract relating to foreign currency forward agreements.

DERIVATIVE COMMODITY INSTRUMENTS

In connection with the purchase of certain raw materials, principally copper, on
behalf of certain customers for future manufacturing requirements, the Company
has entered into commodity forward contracts as deemed appropriate for these
customers to reduce the risk of future price increases. These forward contracts
are accounted for as hedges and, accordingly, gains and losses are deferred and
recognized in cost of sales as part of the product cost. At December 31, 1998,
the Company had entered into contracts hedging certain future commodity
purchases through December 31, 2000, of approximately $42.1 million. The
estimated fair value of these outstanding contracts was approximately $37.5
million at December 31, 1998. The effect of a 10% adverse change in commodity
prices at December 31, 1998 would change the estimated fair value of these
outstanding contracts to $33.7 million The Company is exposed to loss on the
forward contracts in the event of non-performance by the customers whose orders
are covered by such contracts. However, the Company has not closed any contracts
prior to the execution of the underlying sale transactions nor have any of the
underlying sale transactions failed to occur.

STOCK OPTIONS

Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, encourages but does not require companies to record compensation
costs for stock-based employee compensation plans at fair value. The Company has
chosen to continue to account for stock-based compensation using the method
prescribed in Accounting Principles Board Option No. 25, "Accounting for Stock
Issued to Employees," and related interpretations. The Company grants stock
options for a fixed number of shares to employees with an exercise price equal
to the fair value of the shares at the date of grant. Accordingly, the Company
recognizes no compensation for stock option grants.

TRANSLATION TO U.S. DOLLARS

Assets and liabilities of the Company denominated in foreign currency are
translated to U.S. dollars at rates of exchange at the balance sheet date.
Income statement items are translated at average exchange rates during the
period. Translation adjustments arising from changes in exchange rates are
included in the accumulated currency translation adjustment component of
stockholders' equity. Realized exchange gains and losses are included in income.

<PAGE>   48

RESEARCH AND DEVELOPMENT COSTS

Expenditures relating to the development of new products and processes,
including significant improvements and refinements to existing products, are
expensed as incurred. The amounts charged to expense were $1.5 million, $1.4
million and $1.6 million for the years ended December 31, 1998, 1997 and 1996,
respectively.

USE OF ESTIMATES

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement No. 133
Accounting for Derivative Instruments and Hedging Activities. This statement
provides a comprehensive and consistent standard for the recognition and
measurement of derivatives and hedging activities. Statement No. 133 requires
all derivatives to be recorded on the balance sheet at fair value and
establishes special accounting for the following three different types of
hedges: changes in the fair value of assets and liabilities of firm commitments;
hedges of the variable cash flows of forecasted transactions; and hedges of
foreign currency exposures of net investments in foreign operations. Though the
accounting treatment and criteria for each of the three types of hedges is
unique, they all result in recognizing offsetting changes in value or cash flows
of both the hedge and hedged item in earnings in the same period. Changes in the
fair value of derivatives that do not meet the criteria of one of these three
categories of hedges are included in earnings in the period of the change.
Statement No. 133 is effective for fiscal years beginning after June 15, 1999,
but early adoption is allowed. Adoption of this statement is not expected to
have a material effect on the Company's consolidated financial statements.

In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5 Reporting on the Costs of Start-Up Activities. This
Statement of Position provides guidance on the financial reporting of start-up
costs and organizational costs, and requires these costs to be expensed as
incurred. This Statement of Position applies to all non-governmental entities
and, in general, is effective for financial statements for fiscal years
beginning after December 15, 1998. Initial application of this Statement of
Position should be reported as the cumulative effect of a change in accounting
principle, and entities are not required to report the pro forma effects of
retroactive application. The Company will adopt this Statement of Position in
the first quarter of 1999 and will accordingly recognize a pre-tax expense of
approximate $6.0 to $8.0 million as a cumulative effect of the change in
principle.

The reserves for LIFO included in inventories at December 31, 1998 and 1997 are

3. ASSETS HELD FOR RESALE

During 1998, the Company recognized that excess manufacturing capacity existed
in the Company's Greenville, Mississippi fabricated products facility and that
certain action would be required to reduce this excess capacity. It was decided
by management that operations at the Greenville, Mississippi facility would
cease and certain assets related to this operation would be either transferred
to other facilities or sold. Also during 1998 the Company completed the
relocation of the Carrollton, Texas fabricated products facility. The new,
larger facility is also located in Carrollton, Texas, and will accommodate
additional growth.

The net assets of the unoccupied Greenville, Mississippi and Carrollton, Texas
facilities have been recorded at $0.7 million and $2.3 million, respectively,
which are the estimated net proceeds based on an independent assessment of the
market value of these assets. The Company is currently marketing these assets
that are held for resale.

6. FINANCING ARRANGEMENTS AND LONG TERM DEBT

In June 1998, the Company amended certain provisions of the Company's $200
million Revolving Credit Facility (the "Facility"), which included: (i)
increasing the amount of unsecured indebtedness that the Company may incur while
borrowings under the Facility are outstanding; (ii) waiving the requirement that
the proceeds of an offering of senior notes must be used to repay all the
outstanding borrowings under the Facility; and (iii) raising the ratio of total
debt to EBITDA permitted while borrowings are outstanding under the Facility.
The Facility, as amended, matures in full on April 30, 2002, and currently
provides for a floating base interest rate that is, at the Company's election,
either (a) the higher of the federal funds effective rate plus .50% and the
prime rate; or (b) LIBOR plus a specified margin (determined with reference to
the Company's ratio of total debt to EBITDA and the Company's debt rating as
determined by the Standard & Poor's and Moody's Rating Services) of 0.25% to
1.00%. Commitment fees on the unused available portion of the Facility range
from .10% to .50%. As of December 31, 1998, the Company had approximately $67
million in outstanding borrowings and obligations under the Facility and
approximately $133 million in additional borrowing availability thereunder.

The Company originally entered into the Facility in April 1997 to replace the
Company's then existing credit facility, as well as a tender offer for the $99
million in outstanding principal amount of the Company's 10 1/8% Senior
Subordinated Notes due 2002 (the "10 1/8% Notes"). Upon consummation of the
refinancing on April 30, 1997, the Company borrowed approximately $107 million
under the Facility, substantially all of which was used to finance the purchase
of the $98.225 million in 10 1/8% Notes that were tendered as well as related
financing expenses. Accordingly, the Company recorded an extraordinary after-tax
charge of $4,738,000 ($7,520,000 pre-tax) resulting from the early retirement of
the 10 1/8% Notes. On October 31, 1997, the balance of $775,000 in aggregate
principal amount of the 10 1/8% Notes that had remained outstanding was called
for redemption by the Company at 103.8%, pursuant to the terms of the 10 1/8%
Notes.

The Company is currently party to an interest rate swap agreement which
effectively fixes the interest rate on $65,000,000 in principal amount of
floating rate borrowings provided under the Facility at a rate of 6.82% plus the
specified margin of .25% to 1.00%. This agreement expires on May 7, 2002, and is
based on 3-month LIBOR. This interest rate swap is accounted for as a



                                      F-11
<PAGE>   51

hedge; the differential to be paid as interest rates change is accrued and
recognized as an adjustment to interest expense.

In August 1998, the Company issued $150 million in principal amount of 7 3/8%
Senior Notes (the "Senior Notes") due August 1, 2008. The Senior Notes were
issued pursuant to an Indenture, dated as of August 4, 1998, between the Company
and First Union National Bank, as Trustee. The net proceeds from the sale of the
Senior Notes were applied to reduce borrowings under the Facility by
approximately $58 million. The remaining net proceeds will be used for capital
expenditures, potential future acquisitions, working capital and other general
corporate purposes. The Senior Notes (i) have interest payment dates of February
1 and August 1 of each year, commencing February 1, 1999; (ii) are redeemable at
the option of the Company at a redemption price equal to the greater of (a) 100%
of the principal amount of the Senior Notes to be redeemed, or (b) the sum of
the present value of the remaining scheduled payments of principal and interest
thereon from the redemption date to the maturity date, discounted to the
redemption date on a semiannual basis at a rate based upon the yield of the
specified treasury securities plus 25 basis points, plus, in each case, accrued
interest thereon to the date of redemption; (iii) are senior unsecured
obligations of the Company and are pari passu in right of payment with any
existing and future senior unsecured indebtedness of the Company, including
borrowings under the Facility; (iv) are guaranteed by certain of the Company's
subsidiaries; and (v) are subject to the terms of the Indenture, which contain
certain covenants that limit the Company's ability to incur indebtedness secured
by certain liens and to engage in sale/leaseback transactions.

The Company has a non interest bearing loan agreement with the government of
Canada. As of December 31, 1998 and 1997, the Company had outstanding advances
of $980,000 and $1,399,000, respectively. The loan is being repaid in four
annual installments which commenced in 1998.

The Company's credit agreements contain covenants that include requirements to
maintain certain financial ratios and certain other restrictions and
limitations, including the restrictions on payment of dividends by the Company,
limitations on the issuance of additional debt, limitations on investments and
contingent obligations, the redemption of capital stock and the sale or transfer
of assets.

Interest expense is net of interest income and capitalized interest of
$2,792,000 and $1,816,000 in 1998, and $383,000 and $381,000 in 1997, and
$954,000 and $184,000 in 1996, respectively.

7. RETIREMENT AND PENSION PLANS

U.S. PLANS

The Company has established trusteed, noncontributory defined benefit pension
plans covering the majority of all U.S. employees fulfilling minimum age and
service requirements. Benefits are based upon years of service with the Company
and the average of the employee's highest five years of compensation during the
last ten years of employment with the Company. The Company contributes annual
amounts that fall within the range determined to be deductible for federal
income tax purposes.

CANADIAN PLANS

The Company sponsors a defined contribution profit-sharing retirement plan for
the London, Ontario facility employees who are required to contribute 4% of
regular wages, subject to a maximum contribution limit specified by Canadian
income tax regulations. Employer contributions are determined based on the
facility's operating results, which will not be less than the greater of 1% of
regular earnings of participants up to 10% of an adjusted net income as defined
in the agreement. Employer contributions to this plan were $585,000 in 1998,
$630,000 in 1997 and $750,000 in 1996.

The Company has established noncontributory defined benefit pension plans
covering substantially all employees at the Montreal, Quebec and Fergus, Ontario
facilities. The Company contributes the actuarially determined amounts annually
into the plans. Benefits for the hourly employees at the Montreal, Quebec and
Fergus, Ontario facilities are based on years of service and a negotiated rate.
Benefits for salaried employees are based on years of service and the employee's
highest annual average compensation over five consecutive years.

8. POSTRETIREMENT BENEFIT OBLIGATION

In addition to the Company's U.S. defined benefit pension plan, the Company
sponsors a defined benefit health care plan and life insurance plan that
provides postretirement medical benefits and life insurance to substantially all
full-time U.S. employees who have worked ten years after age 50, and widows of
employees who die while employed after age 55 and have at least five years of
service with the Company. This plan is contributory, with retiree contributions
adjusted annually.

Net periodic postretirement benefit cost for the years ended December 31 
includes the following components:

============================================================================================================
</TABLE>

The assumed rate of annual increase in the per capita cost of covered benefits
(i.e. health care cost trend rate) is 5% for 1998 and is assumed to remain at
that level thereafter. The health care cost trend rate assumption has a
significant effect on the amounts reported. For example, increasing the assumed
health care cost trend rate by one percentage point in each year would have
resulted in an increase in the postretirement medical benefit obligation at
December 31, 1998 of $335,000, and an increase in the aggregate of the service
cost and interest cost components of net periodic postretirement benefit cost
for 1998 of $48,000. The weighted average discount rate used in determining the
accumulated postretirement benefit obligation was 7.00% and 7.50% at December
31, 1998 and 1997, respectively.

9. ENVIRONMENTAL REMEDIATION

The Company is subject to extensive U.S. and Canadian federal, state, provincial
and local environmental laws and regulations. These laws, which are constantly
changing, regulate the discharge of materials into the environment. The Company
has received various communications from regulatory authorities concerning
certain environmental matters and has currently been named as a potentially
responsible party ("PRP") at various waste disposal sites. The Company believes
that its potential liability with respect to these waste disposal sites is not
material.

The Company had accrued environmental remediation costs of $3,002,000 at
December 31, 1998, consisting primarily of $34,000 for estimated remediation
costs for the London and Fergus facilities, $1,023,000 for the Decatur facility,
$431,000 for the Greenville facility, $750,000 for the Jackson facility and an
aggregate of $764,000 for the Ardmore facility and the Shawnee facility (with
respect to the Double Eagle Refinery site). Based on information currently
available, the Company believes that the costs of these matters are not
reasonably likely to have a material effect on the Company's business, financial
condition or results of operations.

The Internal Revenue Service is conducting an examination of the Company's U.S.
federal income tax returns for the years 1993 through 1994. The Company believes
that it has made an adequate provision for these matters and that such matters
will not have a material adverse effect on its business, financial condition or
results of operations.

11. CUMULATIVE PREFERRED STOCK

The Company has 500,000 shares authorized for issuance of $1 par value
cumulative preferred stock. Of these shares, there are currently 20,000 shares
of cumulative preferred stock issued and outstanding which must be redeemed by
the Company on March 1, 2002, if not earlier, for $100 per share plus accrued
and unpaid dividends. The cumulative preferred stock provides for annual
dividends at the rate of $14 per share. The dividends accrue quarterly whether
declared or not, and compound quarterly at 14% per annum to the extent unpaid.
At December 31, 1998 and 1997, all accrued dividends had been paid.

The cumulative preferred stock is entitled to a preference, in liquidation, in
the amount of $100 per share, plus any accrued and unpaid dividends and any
related interest. The owners of the cumulative preferred stock are not entitled
to any voting rights, except that in the event that six consecutive quarterly
dividends are not paid, the holders of the cumulative preferred stock are
entitled to vote separately as a class to elect 20% of the directors of the
Company. There are also certain restrictions against the declaration or payment
of dividends on common stock or the acquisition of common stock by the Company
if it is in default on any dividends or redemption payments on the cumulative
preferred stock. Additionally, amendment of the Company's Articles of
Incorporation or changes in the number of authorized stock ranking on a parity
with the preferred stock must be approved by the holders of the cumulative
preferred stock.

12. COMMON STOCK

All holders of common stock are entitled to receive dividends when and if
declared by the Company's Board of Directors (the "Board"), provided that all
dividend requirements of the cumulative preferred stock have been paid.
Additionally, the payment of dividends on the Company's common stock is
restricted under the terms of the Company's various financing agreements. To
date, no dividends have been paid to the holders of the common stock and there
are no immediate plans to institute a dividend.

The Board has adopted a Stockholder Rights Plan designed to protect the Company
and its stockholders from coercive, unfair or inadequate takeover bids. Pursuant
to the Rights Plan, a dividend of one Preferred Share Purchase Right ("Right")
was declared for each share of Common Stock outstanding at the close of business
on February 23, 1996. The Rights are generally not exercisable until ten days
after a person or group acquires, or commences a tender offer that could result
in the party acquiring, 15% of the outstanding shares of Common Stock. Each
Right, should it become exercisable, will enable the owner to buy one
one-thousandth of a share of newly created Series A Junior Participating
Preferred Stock at an exercise price of $175, and, in certain circumstances, to
purchase shares of Common Stock at a substantially reduced price. The Board is
generally entitled to redeem the Rights at $0.01 per Right at any time prior to
the date they become exercisable. The Rights will expire on February 23, 2006.

On September 17, 1998, the Board authorized the Company to purchase up to
1,000,000 shares of the Company's outstanding common stock at market prices from
time to time through September 18, 1999. The aggregate purchase price for such
purchases of common stock shall not exceed $25,000,000. As of December 31, 1998,
the Company had repurchased 784,200 shares.

13. STOCK OPTION PLAN

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Options Issued to Employees" ("APB 25") and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under
Financial Accounting Standards Board Statement No. 123 ("Statement 123"),
Accounting for Stock-Based Compensation, requires use of option valuation models
that were not developed for use in valuing employee stock options. Under APB 25,
no compensation expense is recognized because the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of the grant.

Pro forma information regarding net income and earnings per share is required by
Statement 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1998,
1997 and 1996, respectively: risk free interest rates of 5.29%, 6.32% and 6.34%;
volatility factors of the expected market price of the Company's common stock of
0.331 and a weighted-average expected life of the option of 7 years.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period. The effects of
applying Statement 123 for proforma disclosure may not likely be representative
of the effects on reported proforma net income in future years. The Company's
pro forma information for the years ended December 31 are as follows:

employees. The maximum number of additional shares issuable under the 1993
Equity Plan is 1,225,000 at a price no less than fair market value at the date
of grant. Options granted under the 1993 Equity Plan vest 20% on each
anniversary thereafter and terminate on the 10th anniversary of the date of
grant. Options granted under prior plans remain outstanding but are governed by
the provisions of the 1993 Equity Plan.

The 1993 Stock Option Plan for Outside Directors (the "1993 Directors' Plan")
provides for the issuance of stock options to outside directors at the fair
market value on the date of grant. A maximum of 105,000 shares are issuable
under the 1993 Directors' Plan. The initial options granted vest at 33.3% per
year and all subsequent options granted will vest immediately and terminate on
the 10th anniversary of the date of grant. All initially granted options must be
held one year before being exercised.

The weighted-average exercise price of options outstanding at the beginning of
the 1998, granted during the year, exercised during the year, forfeited during
the year and outstanding at the end of the year is $24.64, $36.78, $15.46,
$35.28 and $29.84, respectively. The weighted average fair value of options
granted in 1998 was $10.76. The weighted average remaining life for options
outstanding at December 31, 1998 is 7.4 years.

The number of options outstanding, weighted-average exercise price,
weighted-average remaining contractual life, vested options and the
weighted-average exercise price of vested options outstanding at December 31,
1998, which were issued prior to August 1993, were 136,837, $6.08, 3.6 years,
136,837 and $6.08, respectively. The number of options outstanding,
weighted-average exercise price, weighted-average remaining contractual life,
vested options and the weighted-average exercise price of vested options
outstanding at December 31, 1998, which were issued after August 1993, were
754,250, $34.15, 8.0 years, 205,117 and $31.08, respectively.

14. COMMITMENTS

Pursuant to various operating lease agreements, at December 31, 1998, the
Company had payment obligations totaling $6,474,000 during the next five years
and thereafter in annual amounts ranging from $1,907,000 to $869,000. Total
rental expense for operating leases amounted to approximately $1,976,000,
$2,027,000 and $1,564,000 for the years 1998, 1997 and 1996, respectively. At
December 31, 1998, the Company had commitments of $5,044,000 for capital
expenditures.

15. RELATED PARTY TRANSACTIONS

During 1996, pursuant to a management consulting and advisory agreement (the
"Agreement"), the Company paid management fees and out-of-pocket expenses of
$450,000 to Genstar Investment Corporation ("GIC"), an affiliate of Genstar
Capital Corporation, a former controlling stockholder of the Company. Under the
terms of the Agreement, the Company paid GIC a management fee of $150,000 per
quarter through September 30, 1996, at which time the Agreement terminated.

16. INDUSTRY SEGMENTS AND FOREIGN OPERATIONS

The Company adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information in 1998, which changes the way the Company
reports information about its operating segments. The information for 1997 and
1996 has been restated from the prior year's 


                                      F-21
<PAGE>   61

presentation in order to conform to the 1998 presentation. The Company's
reportable segments are based on the Company's three product lines: commercial
products, wholesale products and other products. Commercial products consist
primarily of high value-added products sold directly to equipment manufacturers.
Wholesale products are commodity-type plumbing tube products, which are
typically sold to a variety of customers. Other products consist primarily of
commodity-type rod, bar and strip products which are also sold to a variety of
customers.

The accounting policies of the reportable segments are the same as those
described in Note 1 of the Notes to the Consolidated Financial Statements. The
Company evaluates the performance of its operating segments based on sales and
gross profit. During 1998, 1997 and 1996, the Company did not allocate asset
amounts and items of income and expense below gross profit or depreciation and
amortization. Summarized financial information concerning the Company's
reportable segments is shown in the following table:

The Company's manufacturing operations are primarily conducted in the U.S. and
Canada. In 1998, one customer accounted for 10% of the Company's net sales. In
1997, no customer accounted for as much as 10% of the Company's net sales. In
1996, one customer accounted for approximately 11% of the Company's net sales.
The following summarized geographic data is based on estimates that do not
consider fully the extent to which the Company's product development,
engineering, marketing and management activities are interrelated. Thus, the
data is not totally indicative of the extent that each geographic area
contributed to the Company's consolidated operating results.

The Board of Directors
Wolverine Tube, Inc.


We have audited the accompanying consolidated balance sheets of Wolverine Tube,
Inc. and Subsidiaries as of December 31, 1998 and 1997, and the related
consolidated statements of income, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements 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 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 financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Wolverine Tube,
Inc. and Subsidiaries at December 31, 1998 and 1997, and the consolidated
results of their operations and their cash flows for each of the years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.
