WOLVERINE TUBE, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
APRIL 2, 2000
(Unaudited)

NOTE 1. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements include
the accounts of Wolverine Tube, Inc. (the "Company") and its majority-owned
subsidiaries after elimination of significant intercompany accounts and
transactions. The accompanying condensed consolidated financial statements have
been prepared in accordance with instructions to Form 10-Q and do not include
all the information and footnotes required by generally accepted accounting
principles for complete financial statements. The accompanying condensed
consolidated financial statements (and all information in this report) have not
been examined by independent auditors; but, in the opinion of management, all
adjustments, which consist of normal recurring accruals necessary for a fair
presentation of the results for the periods, have been made. The results of
operations for the three-month period ended April 2, 2000 are not necessarily
indicative of the results of operations that may be expected for the year ending
December 31, 2000. For further information, refer to the consolidated financial
statements and notes included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1999.

The Company uses its internal operational reporting cycle for quarterly
financial reporting.

Certain reclassifications have been made to the previously reported consolidated
statement of income for the three-month period ended April 3, 1999 to provide
comparability with the current year presentation.

NOTE 2. CONTINGENCIES

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 one waste disposal site. The Company believes that
its potential liability with respect to this waste disposal site is not
material.

The Company had accrued estimated environmental remediation costs of $2,582,000
at April 2, 2000, consisting primarily of $859,000 for the Decatur, Alabama
facility; $290,000 for the Greenville, Mississippi facility; $730,000 for the
Jackson, Tennessee facility; $314,000 for the Ardmore, Tennessee facility and
$389,000 for the Shawnee, Oklahoma 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
adverse effect on the Company's business, financial condition or results of
operations.

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

Approximately 64% and 60% of the total consolidated inventories at April 2, 2000
and December 31, 1999 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.

NOTE 4. INTEREST EXPENSE, NET

Interest expense is net of interest income and capitalized interest of $216,000
and $43,000 for the three-month period ended April 2, 2000, and $998,000 and
$124,000 for the three-month period ended April 3, 1999, respectively.


NOTE 5. DEBT

The Company has a $200 million Revolving Credit Facility (the "Facility") which
matures on April 30, 2002. The Facility 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% or the prime rate, or (b) LIBOR plus a specified
margin 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 April 2, 2000, the Company had
approximately $46 million in outstanding borrowings and obligations under the
Facility and approximately $154 million in additional borrowing availability
thereunder.

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 Senior Notes (i) have interest
payment 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.

NOTE 6. COMPREHENSIVE INCOME

For the three-month periods ended April 2, 2000 and April 3, 1999, total
comprehensive income was $6,066,000 and $2,885,000, respectively. Comprehensive
income differs from net income due to foreign currency translation adjustments.

NOTE 7. INDUSTRY SEGMENTS

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
original equipment manufacturers. Wholesale products are commodity-type plumbing

NOTE 8. CUMULATIVE EFFECT OF ACCOUNTING CHANGE

During the first quarter of 1999, the Company adopted the American Institute of
Certified Public Accountants' Statement of Position 98-5, Reporting on the Costs
of Start-Up Activities (the "Statement"), which requires that certain costs
related to start-up activities be expensed as incurred. In accordance with the
Statement, the Company recognized a charge for the cumulative effect of a change
in accounting principle of $8.0 million pre-tax ($5.8 million after-tax). The
implementation of the Statement required the Company to write-off the remaining
start-up costs relating primarily to the Company's Roxboro, North Carolina;
Jackson, Tennessee; and Shanghai, China facilities.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

RESULTS OF OPERATIONS

THREE-MONTH PERIOD ENDED APRIL 2, 2000 COMPARED TO
THREE-MONTH PERIOD ENDED APRIL 3, 1999

For the three-month period ended April 2, 2000, consolidated net sales were
$177.8 million, compared with $160.8 million in the three-month period ended
April 3, 1999. The increase in net sales for the three-month period this year
versus last year was primarily due to increased volumes of industrial tube and
strip products, as well as higher average copper prices. The average COMEX
copper price was $0.82 per pound in the most recent three-month period, compared
with $0.64 per pound in the same period a year ago. The primary impact to the
Company of higher copper prices is higher net sales and cost of goods sold. The
cost of copper is generally passed along to the Company's customers and is
included in the cost of goods sold. The Company uses various strategies to
minimize the effect of copper prices on the Company's earnings.

Total pounds shipped for the three-month period of 2000 increased 2.0% to 99.5
million pounds, compared with 97.5 million pounds in the three-month period a
year ago. Shipments of commercial tube products increased 5.5%, primarily as a
result of increased shipments of industrial tube used in the residential air
conditioning industry. Shipments of the Company's wholesale products for the
three-month period of 2000 decreased 19.9% to 16.4 million. The lower shipments
primarily reflect the Company's decision to produce more industrial tube, and,
to a lesser extent, the lower shipments also reflect distributors' desire to
carry less inventory. Rod, bar and strip product shipments for the three-month
period of 2000 increased 15.6% from the three-month period a year ago, primarily
as a result of increased shipments of strip product from the Wolverine
Ratcliffs, Inc. ("WRI") joint entity, formed in mid-July 1999.

Consolidated gross profit increased 5.0% to $23.2 million in the three-month
period of 2000 compared to $22.1 million in the three-month period of 1999. This
increase was primarily the result of increased shipments of industrial tube
(included in commercial products), benefits from previously-enacted cost
reduction programs and improved operating results at the Jackson, Tennessee
facility, which positively affected gross profit to a lesser extent.

Consolidated selling, general and administrative expenses for the three-month
period of 2000 were $8.7 million, as compared to $7.2 million in the three-month
period of 1999. This increase was primarily the result of increased costs due to
the addition of WRI, incremental depreciation and maintenance charges on new
information systems software, increased employee compensation expenses relating
to limited merit increases and performance awards and professional fees.

Consolidated net interest expense for the three-month period in 2000 increased
to $3.3 million from $3.1 million in the three-month period of 1999. This
increase reflects a reduction in interest



                                       8
<PAGE>   11

expense due to a lower outstanding balance on the Company's credit facilities,
which was offset by less interest income in the first quarter of 2000.

The effective tax rate for the first quarter of 2000 was 37.8% compared with
36.4% for the first quarter of 1999. The increase in the effective tax rate
resulted from more income from tax jurisdictions with higher tax rates than in
the first quarter of 1999.

During the first quarter of 1999, the Company adopted the American Institute of
Certified Public Accountants' Statement of Position 98-5, Reporting on the Costs
of Start-Up Activities (the "Statement"), which requires that certain costs
related to start-up activities be expensed as incurred. In accordance with the
Statement, the Company recognized a charge for the cumulative effect of a change
in accounting principle of $8.0 million pre-tax ($5.8 million after-tax). The
implementation of the Statement required the Company to write-off the remaining
start-up costs relating primarily to the Company's Roxboro, North Carolina;
Jackson, Tennessee; and Shanghai, China facilities.

Consolidated net income for the three-month period of 2000 was $6.8 million, or
$0.54 per diluted share, compared to $1.5 million, or $0.10 per diluted share in
the three-month period a year ago. Income before the cumulative effect of an
accounting change in the three-month period of 1999 was $7.2 million, or $0.53
per diluted share.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used for operating activities totaled $2.7 million in the first three
months of 2000 as compared to net cash provided by operating activities of $1.6
million in the first three months of 1999. The decrease in cash provided by
operations in the first three months of 2000 was primarily due to a seasonal
increase in accounts receivable and inventory partially offset by a decrease in
accounts payable. The $14.2 million increase in net accounts receivable from
December 31, 1999 was primarily due to increased sales over year-end 1999
levels.

The Company has a $200 million Revolving Credit Facility (the "Facility"), which
matures on April 30, 2002. The Facility 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% or the prime rate, or (b) LIBOR plus a specified
margin 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 April 2, 2000, the Company had
approximately $46 million in outstanding borrowings and obligations under the
Facility and approximately $154 million in additional borrowing availability
thereunder.

Capital expenditures were $6.7 million for the first three months of 2000
compared to $6.1 million for the first three months of 1999. The Company
currently expects to spend approximately $35 to $40 million in 2000 under its
capital improvement program.

The Company believes that it will be able to satisfy its existing working
capital needs, interest obligations, stock repurchases and capital expenditure
requirements with cash flow from operations and funds available from the
Facility.

ENVIRONMENTAL

The Company's facilities and operations are subject to extensive environmental
laws and regulations. During the three-month period ended April 2, 2000, the
Company spent approximately $8,000 on environmental matters which included
remediation costs, monitoring costs and legal and other costs. The Company has a
reserve of approximately $2.6 million for environmental remediation costs which
is reflected in the Company's Condensed Consolidated Balance Sheet. 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 PRP's 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 PRP's liability to be limited to a prorata share of
an aggregate amount based on the EPA'a worst-case cost scenario to remediate the
site. Under the current proposal, the Company's settlement amount is estimated
to be $389,000.

Decatur, Alabama

In 1999, the Company negotiated a new Consent Order under Section 3008(h) of the
Resource Conservation and Recovery Act (the "Order"). The Order incorporated the
Corrective Measures Study ("CMS") that Henley (a former owner of the facility)
had submitted to the EPA regarding a waste burial site at the Decatur, Alabama
facility. The Order also included an upgrade to an existing chrome groundwater
remediation system. The CMS proposes current monitoring and site maintenance.
The remaining monitoring, legal and other costs related to the groundwater
remediation project are estimated to be $859,000. The cost to the Company to
comply with the CMS, as currently approved, will not have a material 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



                                       10
<PAGE>   13

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 a range
of between $314,000 and $1,100,000 to complete the investigation and develop the
remediation plan for this site.

A 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. The Company entered into a
consent agreement with the Mississippi Department of Environmental Quality (the
"MDEQ") on July 15, 1997. Remediation efforts began in the third quarter of 1997
and are expected to take approximately three years. The Company recently
submitted a report of remediation activities and requested that the MDEQ allow
it to cease active remediation and begin post-closure monitoring. However, there
can be no assurance that remediation efforts will be allowed to be permanently
discontinued, and operations, maintenance and other expenses of 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
had been shared with the former owners of the 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 $290,000 under the
remediation plan the Company adopted, but these costs could increase if
additional remediation is required.

In December 1999, the Company applied for admission into the Mississippi Land
Recycling Program. It is anticipated that the Land Recycling Program will allow
more latitude in remediation decision making and property transfers.

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 had 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 on
currently available information, the



                                       11
<PAGE>   14

Company preliminarily estimates that remediation costs could amount up to
$730,000. However, certain of the remediation costs may be reimbursed pursuant
to the terms of an indemnification agreement between the Company and the
previous owners of the Jackson facility.

Altoona, Pennsylvania

The Company has entered into the State of Pennsylvania Department of
Environmental Protection Act II Program (the "Program"). The Program was entered
to address issues of contamination from closed hazardous waste lagoons and oil
contamination of soil. The chrome lagoons were closed in 1982. The Program is a
voluntary site remediation program which allows the Company to direct the site
evaluation and any eventual remediation. Preliminary costs are estimated at
$185,000 to complete the investigation phase of the Program. Once the
investigation phase is completed, a decision on remediation (if any) will be
made. Insufficient information exists at this point to estimate any remediation
costs or if remediation will be required. The Company is fully indemnified by
the previous owner for any costs associated with the Program, thus no liability
has been recorded at April 2, 2000.

Other

The Company has been named as a party in a Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") lawsuit by Southdown Environmental
Services ("Southdown") and Allworth, Inc. ("Allworth"). The Company is named
with approximately 200 other companies (the "Group") in the suit. The Company,
along with the other members of the Group, contracted with Allworth, and
subsequently Southdown, for treatment, storage and disposal of hazardous wastes
between 1978 and 1995. The suit seeks compensation from the Group for costs
related to environmental cleanup incurred by Southdown, and potentially
Allworth, at the site in Birmingham, Alabama. The site is presently owned by
Philips Services Corporation ("Philips"). To date, the Company has only incurred
legal fees associated with this matter. Negotiations have been ongoing,
unsuccessfully, between Philips, Southdown and Allworth to reach a settlement.
The Company's potential share of liability, if any, is unknown at this point.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

Certain of the statements and subject areas contained herein in "Management's
Discussion and Analysis of Financial Condition and Results of Operations" that
are not based on historical or current facts deal with or may be impacted by
potential future circumstances and developments. Such statements and the
discussion of such subject areas involve, and are therefore qualified by, the
inherent risks and uncertainties surrounding future expectations generally, and
also may materially differ from the Company's actual future experience involving
any one or more of such subject areas. The Company has attempted to identify, in
context, certain of the factors that it currently believes may cause actual
future experience and results to differ from current expectations regarding the
relevant statement or subject area. The Company's operations and results may be
subject to the effect of other risks and uncertainties in addition to the
relevant qualifying factors identified herein, including but not limited to,
cyclicality and seasonality in the industries to which the Company sells its
products, the impact of competitive products and



                                       12

pricing, extraordinary fluctuations in the pricing and supply of the Company's
raw materials, volatility of commodities markets, unanticipated developments in
the areas of environmental compliance and other risks and uncertainties
identified from time to time in the Company's reports filed with the Securities
and Exchange Commission.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There has been no material changes in the Company's market risk exposures
relating to interest rate risk and foreign currency risk that would
significantly affect the quantitative and qualitative disclosures presented in
the Form 10-K filing for the year ended December 31, 1999.

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 Company's risk of future price increases. The amount of
forward contracts and their respective fair values have materially changed since
December 31, 1999 primarily due to the change in copper prices.

At December 31, 1999, the Company had entered into contracts hedging certain
future commodity purchases through May 2001, of $32.6 million. The estimated
fair value of these outstanding contracts was approximately $38.3 million at
December 31, 1999. At April 2, 2000, the Company had entered into contracts
hedging certain future commodity purchases through May 2001, of $30.1 million.
The estimated fair value of these outstanding contracts was approximately $31.9
million at April 2, 2000. The effect of a 10% adverse change in commodity prices
at April 2, 2000 would change the estimated fair value of these outstanding
contracts to $28.7 million.
