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 October 18, 2007. The purpose of the Plan is to aid the Company and its subsidiaries and affiliates in attracting and retaining key personnel.

The purpose of this amendment and restatement is to bring the Plan into compliance with the requirements of Section 409A of the Code and applicable Treasury Regulations thereunder (referred to collectively as “Section 409A”) and to make certain other changes to the Plan. The terms of the Plan shall be interpreted in such manner as to be in compliance with the requirements of Section 409A, including the grandfathering provisions thereof. With respect to Members whose Vesting Date occurred on or before December 31, 2004, such Members’ accrued benefits under the Prior Plan as of December 31, 2004 shall be grandfathered (within the meaning of Section 409A) and remain subject to the terms and conditions of the Prior Plan. This amendment and restatement is in no way intended to materially modify (within the meaning of the term “material modification” under Section 409A) the Prior Plan with respect to such Members’ grandfathered accrued benefits as of December 31, 2004.

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.

Nothing contained in this Plan shall give or be deemed to give any Member or any other person any interest in any property of the Trust or of the Company or any right except to receive such payments as are expressly provided hereunder.

No current or former employee, officer or director of AK Steel Holding Corporation or the Company shall be personally liable to any Member or other person under any provision of this Plan.

Participation shall commence at such time as the Administrator determines after the selected officer enters into any agreements with the Company as the Administrator may require as a condition to participation in this Plan, and provides to the Administrator any documents or other information required by the Administrator, including but not limited to information relating to the officer’s participation in any Qualified Plan.

The Board may remove any Member or Key Management Member from participation in this Plan. With respect to any removed Member or Key Management Member who has

5

attained his Vesting Date, such removal shall not directly or indirectly deprive such Member or Key Management 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 removal.

The Company shall notify in writing those employees selected as Members pursuant to Section 5.1 of their Member status and shall notify in writing any Member or Key Management Member removed from membership pursuant to Section 5.2.

ARTICLE 6: BENEFITS

The Benefit of any Key Management Member as determined above shall not increase after November 25, 2003, 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.

A Member whose employment with the Company terminates after he has attained his Vesting Date but before he has attained age 60 shall be entitled to an Early Retirement Benefit equal to his Regular Benefit provided in Section 6.2 reduced to its actuarial equivalent based on his age as of his Benefit Commencement Date using the actuarial assumptions specified in Exhibit A – Schedule A-2 of the NCPP.

A Member’s Benefit shall be reduced as of the Member’s Benefit Commencement Date by: (a) any accrued benefit under any employer-provided Qualified DB Plan, actuarially adjusted under the terms of the Qualified DB Plan as if the benefit under the Qualified DB Plan commenced at the same time as the Member’s Benefit; and (b) the actuarial equivalent, determined under the assumptions set forth in Section 8.2 of this Plan, of any employer-provided vested benefits accumulated under any Qualified DC Plan.

7

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.

ARTICLE 7: VESTING

A Member who becomes “Permanently Disabled” while employed by the Company shall have a nonforfeitable right to 100% of his Benefit as of the date on which he is determined to be Permanently Disabled, provided he has completed at least five (5) years of Service as of such date. The term “Permanently Disabled” shall have the same meaning under this Plan as under the NCPP or the RAPP, as applicable.

8

The designated beneficiary of a Member who dies while employed by the Company shall have a nonforfeitable right to 100% of his Benefit as of his date of death, provided he has completed at least five (5) years of Service as of such date.

A Member shall have a nonforfeitable right to 100% of his Benefit as of the effective date of any Change of Control which occurs while he is employed by the Company.

ARTICLE 8: PAYMENT

9

Notwithstanding any provision of the Plan to the contrary, with respect to any Member or Key Management Member who on his Termination Date is deemed to be a “specified employee” within the meaning of Section 409A, his Benefit shall not be paid prior to the earlier of: (i) the expiration of the six-month period measured from the date of his “separation from service” (as defined in Section 409A) with the Company, or (ii) his death. Such Member or Key Management Member whose Benefit payment is so delayed shall be entitled to interest on the delayed payment for such six-month period (or shorter period as the case may be), accrued at the average prime rate in effect during such period of delay, which shall be added to his Benefit payable under the Plan. The average prime rate of interest for this purpose shall be the average over such period of the daily prime rate of interest published by the Fifth Third Bank, Cincinnati, Ohio or its successors.

ARTICLE 9: INTERPRETATION, AMENDMENT AND TERMINATION

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 9.2.

10

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 10.2 and 10.4, 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 10.2 and 10.4 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.

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 10.4, no such amendment or termination shall directly or indirectly deprive such Member of all or any portion of his vested Benefit or any right to receive his vested Benefit under the terms of the Plan as in effect immediately before such amendment or termination.

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 9.1 and 9.2. 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 10: MISCELLANEOUS

Any and all rights created under this Plan shall be unfunded and unsecured contractual rights of the Members against the Company. The Company’s obligation under this Plan shall be a mere promise by the Company to make the benefit payments described herein.

11

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.

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.

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.

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.

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.

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.

12

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. Words in the masculine gender include the feminine, and the singular includes the plural, and vice versa, unless qualified by the context.

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.

This Plan is subject to interpretation under federal law and, to the extent applicable, the law of the State of Ohio.
