In the opinion of the management of AK Steel Holding Corporation (“AK Holding”) and AK Steel Corporation (“AK Steel”, and together with AK Holding, the “Company”), the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial position of the Company as of March 31, 2004 and the results of its operations and cash flows for the three- month periods ended March 31, 2003 and 2004. The results of operations for the three months ended March 31, 2004 are not necessarily indicative of the results to be expected for the year ending December 31, 2004. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2003.

2. Earnings Per Share

Three Months Ended March 31,

2003 2004

Income (loss) for calculation of basic and diluted earnings per share: Loss from continuing operations $ (42.4) $ (16.4) Income from discontinued operations 1.6 6.9 Gain on sale of discontinued operations — 174.9

Net income (loss) $ (40.8) $ 165.4

Weighted average common shares (in millions) 108.4 108.7

Net income (loss) per share $ (0.38) $ 1.52

Potentially issuable common shares (in millions) excluded from earnings per share calculation due to antidilutive effect 4.2 5.2

3. Inventories

Inventories are valued at the lower of cost or market. The cost of the majority of inventories is measured on the last in, first out (LIFO) method. Other inventories are measured principally at average cost.

December 31, March 31, 2003 2004

Finished and semi-finished $ 641.8 $ 712.6 Raw materials 180.0 186.7

Total cost 821.8 899.3 Adjustment to state inventories at LIFO value (90.9) (117.3)

Net inventories $ 730.9 $ 782.0

4. Pension and other postretirement benefits

Net periodic benefit costs for pension and other postretirement benefits were as follows:

Pension Benefits Other Benefits Three Months Three Months Ended Ended March 31, March 31,

-4- Table of Contents

The Medicare Prescription Drug, Improvement and Modernization Act of 2003 provides a federal subsidy to sponsors of retiree healthcare benefit plans that include a qualified prescription drug benefit. The Company sponsors such a plan. Based on current temporary guidance, because its benefit plan’s measurement date preceded the effective date of the Act, the Company was not permitted to recognize the effects of the Act until February 8, 2004. The Company expects that savings in per capita prescription claim costs due to the impact of the Act will result in a reduction in the Company’s accumulated postretirement benefit obligation of approximately $140.0. These savings are included in unrecognized actuarial net gains and losses and will be recognized into income over future periods. In 2004, the Company expects to recognize a reduction in net periodic benefit costs related to these savings of approximately $17.0, excluding any possible fourth quarter corridor adjustment. Final authoritative guidance on accounting for the federal subsidy, when issued, could affect these estimates and require the Company to change previously reported information.

5. Common Stock Compensation

Common stock compensation expense related to restricted stock awards granted under the Company’s Stock Incentive Plan (“SIP”) was $1.5 and $2.0 for the three-month periods ended March 31, 2003 and 2004, respectively. The Company uses the intrinsic value method to account for nonqualified stock options granted under the SIP. Had compensation expense for the Company’s stock option plans been determined based on the fair value method, the Company’s net income (loss) and basic and diluted income (loss) per share would have been adjusted as follows:

Three Months Ended March 31,

2003 2004

Net income (loss) as reported $ (40.8) $ 165.4 Additional compensation cost based on fair value recognition, net of tax 0.4 0.4

Net income (loss) as adjusted $ (41.2) $ 165.0

Basic and diluted income (loss) per share as reported $ (0.38) $ 1.52 Additional compensation cost based on fair value recognition per share — —

Basic and diluted income (loss) per share as adjusted $ (0.38) $ 1.52

6. Discontinued Operations

On March 31, 2004, the Company sold Douglas Dynamics, L.L.C. for $264.0, before fees and expenses, and recognized a pre-tax gain of $208.3 ($174.9, after tax, or $1.61 per share) in the first quarter. On April 9, 2004, the Company sold Greens Port Industrial Park for $75.0, before fees and expenses, and expects to recognize a pre-tax gain of approximately $46.0 in the second quarter of 2004. Both businesses were accounted for as discontinued operations. Income from discontinued operations for the three months ended March 31, 2003 and 2004 included the following:

Douglas Dynamics Greens Port

8. Legal Proceedings

The following are updates to the Company’s descriptions of pending legal proceedings and environmental matters reported in its Annual Report on Form 10-K for the calendar year 2003:

As previously reported, on January 2, 2002, John D. West, a former employee, filed a purported class action in the United States District Court for the Southern District of Ohio against the AK Steel Corporation Retirement Accumulation Pension Plan (the “AK RAPP”) and the AK Steel Corporation Benefit Plans Administrative Committee (the “AK BPAC”). The plaintiff claims that the method used under the AK RAPP to determine lump sum distributions does not comply with the Employment Retirement Income Security Act of 1974 (“ERISA”) and results in underpayment of benefits to putative class members. It previously was reported that the plaintiff had filed a motion to certify the case as a class action and that the parties have filed cross-motions for summary judgment on the merits of the plaintiff’s claims. On March 9, 2004, the Court granted the plaintiff’s motion to certify the case as a class action. On April 8, 2004, the Court granted the plaintiff’s motion for partial summary judgment and held that the manner in which the plaintiff’s lump sum disbursement was calculated under the AK RAPP violated ERISA and the Internal Revenue Code. The Court further denied the defendants’ motion for summary judgment and ordered that the matter proceed to trial on the issue of damages. No trial date has yet been set. The defendants intend to continue to contest this matter vigorously.

As previously reported, in April 2000 an action was filed in the United States District Court for the Southern District of Ohio by Bernard Fidel and others against the Company and certain of its directors and officers. The plaintiffs allege material misstatements and omissions in the Company’s public disclosure about its business and operations. It previously was reported that the parties have entered into a settlement agreement, which is subject to court approval. On March 30, 2004, the Court entered an Order preliminarily approving the settlement agreement and setting July 9, 2004 as the date for a final settlement hearing in the matter. The Company does not consider the amount of the settlement to be material and, in any event, the settlement amount is well within the limits of the Company’s applicable insurance.

As previously reported, on December 10, 2003, Richard M. Wardrop, Jr., the Company’s former chairman and CEO, filed an arbitration demand in which he asserted claims for benefits under a written severance agreement and under the Company’s Executive Minimum and Supplemental Retirement Plan as a result of the termination of his employment with the Company in September 2003. The total amount of his claims was in excess of $51.0. In April 2004, the Company and Mr. Wardrop reached a settlement of his claims which involved an agreed-upon payment of an amount significantly less than was claimed by Mr. Wardrop. The settlement involves a lump-sum pension payment that was paid entirely from a portion of the funds maintained in a “rabbi trust” account. The Company expects that the settlement will have no material impact on its earnings or liquidity. As part of the settlement, Mr. Wardrop’s arbitration proceeding has been terminated.

-6- Table of Contents

As previously reported, the State of Ohio has asserted claims against the Company that air emissions from the operation of the blast furnace and basic oxygen furnace at the Company’s Middletown Works were causing a public nuisance. In June 2000, AK Steel filed a verified complaint against the State of Ohio and the Ohio Environmental Protection Agency (“OEPA”) in the Court of Common Pleas for Butler County, Ohio (the “State Action”) seeking a declaration, among other things, that the blast furnace and basic oxygen furnaces at the Middletown Works were not causing a public nuisance, and that AK Steel was in compliance with its operating permits for those facilities. It previously was reported that AK Steel and OEPA have been engaged in settlement discussions related to the OEPA air nuisance claims. On March 31, 2004, AK Steel and the OEPA executed and filed an agreed-upon Consent Order in the Court of Common Pleas for Butler County, Ohio (the “Consent Order”). A major component of the Consent Order is AK Steel’s commitment to install control equipment at the Middletown Works blast furnace to meet MACT standards of the federal Clean Air Act by May 2005, one year in advance of the mandatory compliance date. AK Steel also agreed to implement a community response program, a neighborhood cleaning program and a green belt extension, to continue intra-plant employee busing and to pay a civil penalty of approximately $1.7, of which approximately $0.3 will be paid in the form of cash and the rest will be offset by credits for supplemental environmental projects. As a result of the Consent Order, all of the OEPA’s air nuisance claims relating to the Middletown Works blast furnace and basic oxygen furnaces have been resolved and the State Action has been dismissed. Certain appeals also previously reported in the Company’s Form 10-K related to the OEPA air nuisance claims are in the process of being dismissed.

9. New Accounting Pronouncement

In the quarter ended March 31, 2004, the Company adopted the revised FASB Interpretation No. 46, “Consolidation of Variable Interest Entities.” The revised interpretation requires the Company, under certain circumstances, to consolidate all variable interest entities. The adoption of the Interpretation did not have a material effect on the Company’s financial position, results of operations or cash flows.

10. Supplemental Guarantor Information

AK Holding, along with Douglas Dynamics, L.L.C., AK Tube LLC and AKS Investments, Inc. (the “Guarantor Subsidiaries”), fully and unconditionally, jointly and severally guarantee the payment of interest, principal and premium, if any, on AK Steel’s 9% Senior Notes Due 2007, 8 7/8% Senior Notes Due 2008, 7 7/8% Senior Notes Due 2009, 7 3/4% Senior Notes Due 2012 and Senior Secured Notes Due 2004. On March 31, 2004, Douglas Dynamics, L.L.C. was sold (see Note 6). AK Steel’s other subsidiaries are not guarantors of these notes. The Company has determined that full financial statements and other disclosures concerning AK Holding and the Guarantor Subsidiaries would not be material to investors and, accordingly, those financial statements are not presented. The following supplemental consolidating financial statements present information about AK Holding, AK Steel, the Guarantor Subsidiaries and AK Steel’s other subsidiaries.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (dollars in millions, except per share and per ton data)

Results of Operations

AK Steel’s operations consist of seven steelmaking and finishing plants that produce flat-rolled carbon steels, including premium quality coated, cold-rolled and hot-rolled products, and specialty stainless and electrical steels that are sold in slab, hot band, sheet and strip forms. Its operations also include AK Tube LLC, which further finishes flat-rolled steel into welded steel tubing, and European trading companies that buy and sell steel and steel products.

Steel shipments for the three months ended March 31, 2004 and 2003 were 1,514,300 tons and 1,365,400 tons, respectively. The 11% increase in tons shipped in the current year first quarter was primarily a result of strong demand from customers in the automotive, appliance, construction and manufacturing markets. For the three months ended March 31, 2004, value-added products comprised 93.7% of total shipments, up from 89.1% reported in the first three months of 2003 on significantly stronger shipments of coated and cold-rolled carbon steel products and a doubling of tubular steel product shipments as the result of the acquisition of ArvinMeritor’s tubing facility in the third quarter of 2003.

For the Three Months Ended March 31,

(tons in thousands) 2003 2004

Stainless/electrical 226.7 16.6% 239.6 15.8% Coated 687.3 50.3% 809.6 53.5% Cold-rolled 278.2 20.4% 316.3 20.9% Tubular 24.8 1.8% 52.6 3.5%

Subtotal value-added shipments 1,217.0 89.1% 1,418.1 93.7%

Hot-rolled 85.3 6.2% 47.3 3.1% Secondary 63.1 4.7% 48.9 3.2%

Total shipments 1,365.4 100.0% 1,514.3 100.0%

For the quarter ended March 31, 2004, net sales were $1,134.4, a 15% increase from the $985.3 reported for the corresponding period in 2003. Net sales increased due to higher shipment volumes, improved product mix and higher prices across all product lines. The Company’s average steel selling price increased from $702 per ton in the first three months of 2003 to $747 per ton in the first three months of 2004 due to price increases, and the implementation of raw material and energy cost surcharges, both primarily on sales in the spot market. The price increases reflect the global increase in demand for steel, while the surcharges were imposed in response to unprecedented increases in the costs of energy, particularly natural gas, and certain key raw materials, including steel scrap, purchased carbon slabs, coal and coke.

For the first quarter of 2004, the Company recorded an operating profit of $1.5 compared to a $43.1 operating loss for the first quarter of 2003. The year-over- year improvement resulted from increased sales and lower operating and overhead costs that reflected the benefits of salaried workforce reductions and other cost containment efforts. However, in the three months ended March 31, 2004 and 2003, LIFO charges of $26.4 and $13.5, respectively, reflected continued increasing costs for key raw materials and energy, as well as higher employee benefit costs. The 2003 operating loss also included a charge of $3.0 for an unplanned blast furnace outage.

On March 31, 2004, the Company sold Douglas Dynamics, L.L.C. for $264.0, before fees and expenses, and recognized a pre-tax gain of $208.3 ($174.9, after tax, or $1.61 per share) in the first quarter. On April 9, 2004, the Company sold Greens Port Industrial Park for $75.0, before fees and expenses, and expects to recognize a pre-tax gain of approximately $46.0 in the second quarter of 2004. Both businesses were accounted for as discontinued operations and together generated after-tax income of $6.9 and $1.6 during the first quarter of 2004 and 2003, respectively.

During the first quarter of 2003, the effective income tax rate on loss from continuing operations and income from discontinued operations approximated federal and state statutory rates. In the first quarter of 2004, the effective tax rate applied to the loss from continuing operations, likewise, approximates statutory rates. However, an effective rate of approximately 16% was applied to the operating income of discontinued operations and the gain on the sale of Douglas Dynamics. This lower rate results from the recognition of a benefit the Company estimates it will realize in 2004 from the use of net operating loss carryovers that had previously been reduced by a deferred tax asset valuation allowance. The actual effective tax rate applied to discontinued operations for the year 2004 will depend on the amount of taxable income or loss generated by the Company in the year.

-12- Table of Contents

The Company’s net income in the three months ended March 31, 2004 was $165.4, or $1.52 per share, compared to a net loss of $40.8, or $0.38 per share, in the first quarter of 2003. The 2004 favorable variance was primarily due to the gain on the sale of Douglas Dynamics and improved operating results from the steel operations.

Outlook

The Company expects second quarter 2004 shipments to approximate first quarter levels, with continued robust shipments to automotive customers and improving demand for stainless and electrical steels. The percentage of value-added products to total shipments is expected to approximate the 94% experienced in the first quarter. Strong spot market pricing should continue due to previously announced increases in base prices and surcharges with overall average selling prices expected to rise approximately 8% from the first quarter.

The Company expects second quarter costs to increase, as significantly higher purchased slab prices and slightly higher natural gas and iron ore prices outstrip additional savings from cost containment measures. In addition, although steel scrap prices recently have begun to decline from March 2004 highs, scrap costs recognized in cost of products sold during the second quarter are expected to be higher than in the first quarter. A planned maintenance outage at the Ashland Works blast furnace in the second quarter is expected to negatively impact operating results by approximately $16.0. Overall, the Company expects modestly improved operating results in the second quarter as compared to the first quarter of 2004.

As described below, net proceeds from the sales of Douglas Dynamics and Greens Port Industrial Park will be used primarily to reduce outstanding debt and reinvest in the business. The Company expects to record a second quarter pre-tax charge of approximately $3.0 related to the redemption of its Senior Secured Notes.

The Medicare Prescription Drug, Improvement and Modernization Act of 2003 provides a federal subsidy to sponsors of retiree healthcare benefit plans that include a qualified prescription drug benefit. The Company sponsors such a plan. Based on current temporary guidance, because its benefit plan’s measurement date preceded the effective date of the Act, the Company was not permitted to recognize the effects of the Act until February 8, 2004. The Company expects that savings in per capita prescription claim costs due to the impact of the Act will result in a reduction in the Company’s accumulated postretirement benefit obligation of approximately $140.0. These savings are included in unrecognized actuarial net gains and losses and will be recognized into income over future periods. In 2004, the Company expects to recognize a reduction in net periodic benefit costs related to these savings of approximately $17.0, excluding any possible fourth quarter corridor adjustment. Final authoritative guidance on accounting for the federal subsidy, when issued, could affect these estimates and require the Company to change previously reported information.

Liquidity and Capital Resources

At March 31, 2004, the Company had $299.9 of cash and cash equivalents, $127.2 of availability under a $300.0 accounts receivable purchase credit facility and $308.8 of availability under a $400.0 inventory credit facility. At March 31, 2004, there were no outstanding borrowings under the inventory facility; however, the Company had outstanding borrowings of $80.0 under the accounts receivable facility. Total availability under these facilities was also reduced by $90.8 of outstanding letters of credit and reduced pools of eligible collateral. Availability under each facility fluctuates monthly with changes in the levels of eligible receivables and inventories. The Company believes it has adequate liquidity to meet its anticipated cash needs for capital investments, working capital, employee benefit obligations, debt service and the funding of operations.

Cash used by operations totaled $119.1 for the three months ended March 31, 2004. Net cash generated by the Company’s operations was more than offset by $162.3 of cash used to increase net working capital. Accounts receivable rose as a result of increased sales, while inventories grew due to the impact of rising costs and increases in purchased slabs in anticipation of a second quarter blast furnace outage. Accounts payable decreased due to more rapid payment for certain raw materials that have been subject to sharply increasing demand.

During the three months ended March 31, 2004, cash generated by investing activities totaled $271.8, including $263.9 from the sale of Douglas Dynamics. In the first three months of 2004, the Company used $10.8 for capital investments. Capital spending for the year 2004 is expected to total approximately $125.0.

During the three months ended March 31, 2004, cash flows from financing activities generated $79.7, primarily from utilization of the accounts receivable credit facility.

The sales of Douglas Dynamics in March 2004 and Greens Port Industrial Park in early April 2004 generated aggregate proceeds, net of fees and expenses, of approximately $334.0. A portion of these proceeds are being used in the second quarter to reduce outstanding debt, including the April repayment of the $80.0 outstanding balance under the accounts receivable facility and the early redemption in May of the remaining $62.5 of the Company’s

-13- Table of Contents

Senior Secured Notes due December 2004. The Company also will use part of the proceeds to fund future capital investments.

Following redemption of the Senior Secured Notes, the Company will have no scheduled debt maturities before 2007. In addition, the Pension Funding Equity Act of 2004 was signed into law in early April 2004. This legislation reduces the Company’s funding obligations during the next two years by increasing the discount rate used to value pension plans and deferring deficit reduction contributions. The Company was under no obligation to fund its pension trusts in 2004 and expects that, as a result of the newly enacted legislation, it will have no pension funding obligation in 2005. Annual pension funding obligation amounts after 2005 will depend on pension plan investment performance, interest rates and other factors, and could be substantial.

Forward-Looking Statements

Certain statements in this Form 10-Q, particularly those in the paragraph entitled “Outlook,” reflect management’s estimates and beliefs and are intended to be, and are hereby identified as “forward-looking statements” for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. As discussed in its Form 10-K for the year ended December 31, 2003, the Company cautions readers that such forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those currently expected by management.

Item 4. Controls and Procedures

With the participation of management, the Company’s chief executive officer and its chief financial officer evaluated the effectiveness of the Company’s disclosure controls and procedures as of March 31, 2004. Based upon this evaluation, the chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) were effective as of March 31, 2004.

There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the Company’s fiscal quarter ended March 31, 2004, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The following are updates to the Company’s descriptions of pending legal proceedings reported in its Annual Report on Form 10-K for the calendar year 2003:

As previously reported, on January 2, 2002 John D. West, a former employee, filed a purported class action in the United States District Court for the Southern District of Ohio against the AK Steel Corporation Retirement Accumulation Pension Plan (the “AK RAPP”) and the AK Steel Corporation Benefit Plans Administrative Committee (the “AK BPAC”). The plaintiff claims that the method used under the AK RAPP to determine lump sum distributions does not comply with the Employment Retirement Income Security Act of 1974 (“ERISA”) and results in underpayment of benefits to putative class members. It previously was reported that the plaintiff had filed a motion to certify the case as a class action and that the parties have filed cross-motions for summary judgment on the merits of the plaintiff’s claims. On March 9, 2004, the Court granted the plaintiff’s motion to certify the case as a class action. On April 8, 2004, the Court granted the plaintiff’s motion for partial summary judgment and held that the manner in which the plaintiff’s lump sum disbursement was calculated under the AK RAPP violated ERISA and the Internal Revenue Code. The Court further denied the defendants’ motion for summary judgment and ordered that the matter proceed to trial on the issue of damages. No trial date has yet been set. The defendants intend to continue to contest this matter vigorously.

As previously reported, in April 2000 an action was filed in the United States District Court for the Southern District of Ohio by Bernard Fidel and others against the Company and certain of its directors and officers. The plaintiffs allege material misstatements and omissions in the Company’s public disclosure about its business and operations. It previously was reported that the parties have entered into a settlement agreement, which is subject to court approval. On March 30, 2004, the Court entered an Order preliminarily approving the settlement agreement and setting July 9, 2004 as the date for a final settlement hearing in the matter. The Company does not consider the amount of the settlement to be material and, in any event, the settlement amount is well within the limits of the Company’s applicable insurance.

-14- Table of Contents

As previously reported, on December 10, 2003, Richard M. Wardrop, Jr., the Company’s former chairman and CEO, filed an arbitration demand in which he asserted claims for benefits under a written severance agreement and under the Company’s Executive Minimum and Supplemental Retirement Plan as a result of the termination of his employment with the Company in September 2003. The total amount of his claims was in excess of $51.0. In April 2004, the Company and Mr. Wardrop reached a settlement of his claims which involved an agreed-upon payment of an amount significantly less than was claimed by Mr. Wardrop. The settlement involves a lump-sum pension payment that was paid entirely from a portion of the funds maintained in a “rabbi trust” account. The Company expects that the settlement will have no material impact on its earnings or liquidity. As part of the settlement, Mr. Wardrop’s arbitration proceeding has been terminated.

Item 2. Changes in Securities, Use of Proceeds and Issuer Purchases of Equity Securities

Total 35,245 $ 4.82 0 $ 59.5

During the quarter, the Company repurchased shares of common stock owned by participants in its restricted stock awards program under the terms of its Stock Incentive Plan. In order to satisfy the requirement that an amount be withheld that is sufficient to pay federal, state and local taxes due upon the vesting of the restricted stock, employees are permitted to have the Company withhold shares having a fair market value equal to the tax which could be imposed on the transaction. The Company repurchases the withheld shares at the quoted average of high and low prices on the day the participant elects to have the shares withheld.

On April 25, 2000, the Company announced that its Board of Directors had authorized the Company to repurchase, from time to time, up to $100.0 of its outstanding equity securities. The Company has not repurchased its stock under this program since the third quarter of 2000 and cannot currently reacquire its stock under a covenant contained in the instruments governing its outstanding senior debt.

Item 5. Other Information

The following are updates to the Company’s descriptions of pending environmental matters reported in its Annual Report on Form 10-K for the calendar year 2003:

As previously reported, the State of Ohio has asserted claims against the Company that air emissions from the operation of the blast furnace and basic oxygen furnace at the Company’s Middletown Works were causing a public nuisance. In June 2000, AK Steel filed a verified complaint against the State of Ohio and the Ohio Environmental Protection Agency (“OEPA”) in the Court of Common Pleas for Butler County, Ohio (the “State Action”) seeking a declaration, among other things, that the blast furnace and basic oxygen furnaces at the Middletown Works were not causing a public nuisance, and that AK Steel was in compliance with its operating permits for those facilities. It previously was reported that AK Steel and OEPA have been engaged in settlement discussions related to the OEPA air nuisance claims. On March 31, 2004, AK Steel and the OEPA executed and filed an agreed-upon Consent Order in the Court of Common Pleas for Butler County, Ohio (the “Consent Order”). A major component of the Consent Order is AK Steel’s commitment to install pollution control equipment at the Middletown Works blast furnace to meet MACT standards of the federal Clean Air Act by May 2005, one year in advance of the mandatory compliance date. AK Steel also agreed to implement a community response program, a neighborhood cleaning program and a green belt extension, to continue intra-plant employee busing and to pay a civil penalty of approximately $1.7, of which approximately $0.3 will be paid in the form of cash and the rest will be offset by credits for supplemental environmental projects. As a result of the Consent Order, all of the OEPA’s air nuisance claims relating to the Middletown Works blast furnace and basic oxygen furnaces have been resolved and the State Action has been dismissed. Certain appeals also previously reported in the Company’s Form 10-K related to the OEPA air nuisance claims are in the process of being dismissed.

ARTICLE 1: INTRODUCTION AND PURPOSE

AK Steel Corporation hereby amends and restates the AK Steel Corporation Executive Minimum and Supplemental Retirement Plan (“Plan”), effective as of November 25, 2003. The Plan was last amended and restated as of January 20, 2000. The purpose of the Plan is to aid the Company and its subsidiaries and affiliates in attracting and retaining key personnel.

The Plan is an unfunded deferred compensation arrangement maintained by the Company for the purpose of providing supplemental retirement benefits for a select group of management or highly compensated employees within the meaning of Section 201(2) and 301(a)(3) of the Employee Retirement Income Security Act of 1974, as amended.

Benefit shall be payable under this Plan if a Member’s employment with the Company terminates for any reason prior to his Vesting Date.

(b) With respect to a Key Management Member who attained his Vesting Date under the Prior Plan before the Effective Date, his accrued benefit under this Plan shall be his Benefit under the terms of the Prior Plan (after offset for other pensions as provided therein) determined immediately before the Effective Date. With respect to a Key Management Member who has not attained his Vesting Date under the Prior Plan before the Effective Date, his accrued benefit under this Plan shall be his Regular Benefit under the terms of the Prior Plan (after offset for other pensions as provided therein) determined immediately before the Effective Date, times the lesser of:

(1) the percentage obtained by dividing his Service as of the Effective Date by 10; or

(2) the percentage obtained by dividing his Key Management Service as of the Effective Date by 5.

The Benefit of any Key Management Member as determined above shall not increase after the Effective Date, and shall not be payable under this Plan if such Key Management Member’s employment with the Company terminates for any reason prior to his Vesting Date.

6.2 Regular Benefit

(a) Except as provided in (b) below, a Member’s Regular Benefit is a monthly payment for the Member’s lifetime, commencing on the first day of the month coinciding with or next following the later of the Member’s 60th birthday or the Member’s Termination Date and payable in the form provided in Section 7.1, which is in an amount equal to the greater of:

(b) With respect to any Member whose Vesting Date occurred prior to the Effective Date, his Regular Benefit shall be the greater of his

Grandfathered Benefit or the amount determined in (a) above.

6.3 Early Retirement Benefit

Any Member (or Key Management Member) whose employment with the Company terminates after he has attained his Vesting Date, may elect, as soon as administratively feasible after his Termination Date, to commence payment of his Benefit on the first day of the month coinciding with or next following his 55th birthday (or such earlier date as may be approved by the Administrator in its sole discretion). Such Early Retirement Benefit shall be equal to his Regular Benefit provided in Section 6.2 (or, in the case of a Key Management Member, his Benefit under Section 6.1(b)) reduced to its actuarial equivalent based on his age as of such elected commencement date and on the actuarial assumptions used by the enrolled actuary for the NCPP to determine a participant’s early retirement benefit under the NCPP.

6.4 Offset for Other Pensions

A Member’s Benefit shall be reduced as of the Member’s Termination Date by: (a) any accrued benefit under any employer-provided Qualified DB Plan, actuarially adjusted as if the benefit under the Qualified DB Plan commenced at the same time as the Member’s Benefit; or (b) the actuarial equivalent of any employer-provided vested benefits accumulated under any Qualified DC Plan.

6.5 Non-Duplication

A Member shall not be eligible for benefits under any other non-qualified supplemental retirement benefit plan maintained by the Company for the purpose of providing benefits not permitted to be paid under any Qualified DB Plan. Nothing herein shall prohibit participation by any Member in the AK Steel Corporation Executive Deferred Compensation Plan or the AK Steel Corporation Supplemental Thrift Plan.

A lump sum form of payment may be available if approved by the Administrator in its sole discretion. In the case of a Member who is married when payment of his Benefit is to commence, unless the Member’s Spouse consents in writing

to the Member’s election of the single life annuity (or the lump sum form of payment, if available), the automatic form of payment of his Benefit shall be a joint and 50% surviving spouse annuity which shall be the actuarial equivalent of the basic form single life annuity, and which provides a lifetime benefit for the Member and a lifetime benefit for his Spouse equal to 50% of the benefit payable to the Member. The monthly amount of any annuity shall be determined by the enrolled actuary for the NCPP based on the actuarial assumptions contained in the NCPP.

(b) With respect to any Member whose Vesting Date occurred prior to the Effective Date, an amount equal to his Grandfathered Benefit shall be paid in a single lump sum payment, and any balance of his Benefit shall be paid in accordance with (a) above; provided however, such Member may elect the same form of payment with respect to his entire Benefit in accordance with (a) above, subject to approval by the Administrator.

(c) Any lump sum payment to a Member shall be determined in accordance with Section 7.2, and shall be made to the Member, or in the case of the Member’s death, to the Member’s designated beneficiary, within 30 days following the Member’s Termination Date. Any designation of beneficiary shall be made by the Member on an election form filed with the administrator and may be changed by the Member at any time by filing another election form containing the revised instructions. If no beneficiary is designated or no designated beneficiary survives the Member, payment shall be made to the Member’s estate.

(d) A Key Management Member’s Benefit shall be paid in accordance with the terms of the Prior Plan, provided however, with respect to any Key Management Member who has not attained his Vesting Date under the Prior Plan as of the Effective Date, his Benefit shall be paid in the manner set forth in (a) above.

7.2 Lump-Sum Valuation

(a) The lump-sum present value of a Member’s Benefit shall be the actuarial equivalent of his Benefit payable as a single life annuity as set forth in

Section 7.1(a).

8 (b) Subject to the provisions of (c) below, the lump-sum present value of a Member’s Benefit shall be determined by the enrolled actuary for the NCPP based upon assumptions approved by the Administrator in its sole discretion. The assumptions may be changed at any time, and from time to time, but any change shall be valid only with respect to Termination Dates occurring twelve or more months after the change is approved.

(c) Unless otherwise directed by the Administrator, the lump-sum present value of a Member’s Benefit shall be calculated as of the Member’s Termination Date based upon : (i) the 60-month average of the Pension Benefit Guaranty Corporation immediate annuity interest rate in effect during each of the 60 months preceding the month in which the Termination Date occurs, (ii) the age of the Member, (iii) the 1984 Unisex Pension Table (UP84) and (iv) such other actuarial assumptions as would apply under the NCPP. The lump sum present value of any Grandfathered Benefit shall be determined under the applicable provisions of the Prior Plan.

ARTICLE 8: INTERPRETATION, AMENDMENT AND TERMINATION

8.1 Interpretation of the Plan

This document contains the terms of the Plan. However, the Administrator shall have, and the Board expressly reserves to itself and its designate, the broadest possible power to exercise its discretion to interpret the terms of this Plan and to resolve any question regarding any person’s rights under the Plan. Any such interpretation shall be final and binding upon a Member, the Member’s spouse and heirs and subject to review only in accordance with Section 8.2.

8.2 Claims Procedure

Any Member or other person questioning the rights of any person under the Plan shall submit such question in writing to the Administrator, or its designate, for resolution. No person shall have any claim or cause of action for any benefit under this Plan until the Administrator, or its designate, has responded to such written claim, which response shall not be unreasonably delayed. Except as to disputes described in Sections 9.2 and 9.4, it is the intent of the Company, and each Member agrees as a condition of membership, that any judicial review of any decision hereunder shall be limited to a determination of whether the Administrator, or its designate, acted arbitrarily or capriciously, and that any decision of the Administrator, or its designate shall be enforced unless the action taken is found by a court of competent jurisdiction to have been arbitrary or capricious. Disputes described in Sections 9.2 and 9.4 may be resolved by binding arbitration, if mutually agreed by the Member and the Administrator, or by litigation; and in either case such action may proceed without the necessity of exhausting any other remedies that may be available under this Plan.

9 8.3 Amendment or Termination of the Plan

The Board may, at any time, with or without notice to any person, amend or terminate this Plan. With respect to any Member who has attained his Vesting Date, and subject to Section 9.4, no such amendment or termination shall directly or indirectly deprive such Member of all or any portion of his Benefit or any right to receive his Benefit under the terms of the Plan as in effect immediately before such amendment or termination.

8.4 No Cause of Action

No Member shall have any right, claim or cause of action against any person or entity to appeal the denial of a benefit by the Administrator except as provided in Sections 8.1 and 8.2. In addition, no Member, and no person claiming by, through or on behalf of a Member, shall have any claim to or cause of action for any benefit under this Plan which might have been earned but for the amendment or termination of the Plan, or the termination of the Member’s employment or the removal of the Member from participation under this Plan.

ARTICLE 9: MISCELLANEOUS

9.1 Unsecured General Creditor

Any and all rights created under this Plan shall be unfunded and unsecured contractual rights of the Members against the Company.

Members shall have no legal or equitable right, interest or other claim in any property or assets of the Company by reason of the establishment of this Plan.

9.2 Obligations to the Company

If a Member becomes entitled to a distribution of benefits under this Plan, and if at such time the Member has any outstanding debt, obligation or other liability representing an amount certain owed to the Company, then the Company may offset such amount against the amount of benefits otherwise distributable under the Plan. Such determination shall be made by the Administrator.

9.3 Assignability

No Member shall have any right to anticipate, alienate, assign, sell, transfer, pledge, encumber, attach, mortgage or otherwise hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder. No part of the amounts payable hereunder shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance, nor shall any person have any other claim to any benefit payable under this Plan as a result of a divorce or the Member’s, or any other person’s bankruptcy or insolvency.

10 9.4 Forfeiture

Notwithstanding any provision in the Plan to the contrary, any Member terminated for Cause shall forfeit all rights under this Plan. “Cause” means a willful engaging in gross misconduct demonstrably injurious to the Company. “Willful” means an act or omission in bad faith and without reasonable belief that such act or omission was in the best interests of the Company. Any such determination shall be made by the Board. Each Member shall be entitled to a statement of the facts alleged as a basis for the Board’s determination that a Member has been terminated for Cause and shall be permitted an opportunity to present, in person, for the Board’s consideration, in such manner as the Board shall direct, any facts or arguments on the Member’s behalf as the Member or his representative may determine.

9.5 Sale of Business

The sale as a going business of (i) the Company or (ii) substantially all of the assets of the Company shall not be a termination of Service for the purpose of establishing a Member’s right to receive benefits under this Plan.

9.6 Employment Not Guaranteed

The establishment of this Plan, a Member’s appointment as a Member of the Plan, any provision of this Plan, or any action taken hereunder, shall not be or be construed as a contract of employment for any definite term. The Company may take any action related to a Member’s employment without regard to the effect such action has or may have on a Member’s rights hereunder.

9.7 Captions

The captions to the articles, sections and paragraphs of this Plan are for convenience only and shall not control or affect the meaning or construction of any of its provisions.

9.8 Validity

In the event any provision of this Plan is found by a court of competent jurisdiction to be invalid, void or unenforceable, such provision shall be stricken and the remaining provisions shall continue in full force and effect.

9.9 Applicable Law
