ARTICLE 2 DEFINITIONS ----------- The words and phrases used in the Plan shall have the same meanings as provided under Article 2 of the MichCon Retirement Plan (the "Qualified Plan"), unless otherwise defined in the Plan or the context clearly requires otherwise. ARTICLE 3 PURPOSE ------- The principal purpose of the Plan is to provide for the payment of certain benefits that would not otherwise be payable under the Qualified Plan. Such benefits shall be payable to certain employees of the Company and any other corporation which is a Participating Employer under the Qualified Plan. 1 ARTICLE 4 EFFECTIVE DATE -------------- The effective date of the Plan for the Company shall be March 31, 1988 and for any Participating Employer shall be the date established by resolution of the Board of Directors of the particular Participating Employer at the time of adoption of the Plan. ARTICLE 5 ELIGIBILITY ----------- All employees of Participating Employers whose benefits under the Qualified Plan are limited because of the limitation on compensation under Section 401(a)(17) of the Code, the limitation on benefits and contributions under Section 415 of the Code, or any other provision of the Code or other law that the Committee hereafter designates shall be eligible for the benefits provided by this Plan. Also, all employees of Participating Employers who are participating in the MichCon Supplemental Savings Plan shall be eligible for benefits provided by this Plan. Notwithstanding the foregoing, no employee shall be eligible for benefits provided by this Plan until such employee has satisfied the eligibility requirements of the Qualified Plan. ARTICLE 6 EMPLOYERS' OBLIGATION --------------------- The Participating Employers shall pay under this Plan any amount that any eligible employee would have been entitled to receive under the Qualified Plan but for the limitation on compensation under Section 401(a)(17) of the Code, the limitation on benefits and contributions under Section 415 of the Code, and any other provision of the Code or other law that the Committee hereafter designates. Also, the Participating Employers shall pay under this Plan any amount that any eligible employee would have been entitled to receive under the Qualified Plan but 2 for the exclusion of deferrals under the MichCon Supplemental Savings Plan from the definition of Primary Monthly Earnings in the Qualified Plan. Such payments shall be made by the particular Participating Employer which last employed the employee with respect to whom the payment is to be made. ARTICLE 7 PAYMENT OF BENEFITS ------------------- Payments made under this Plan shall be made in all respects at the same time, in the same manner and to the same person as would have been the case under the Qualified Plan had the limitations described in Article 6 not been applicable and the payment had been made under the Qualified Plan. ARTICLE 8 UNFUNDED PLAN ------------- This Plan shall not be a funded plan. Notwithstanding that, the Participating Employers may set aside or otherwise earmark company assets for payment of the benefits payable hereunder. Title to and ownership of such assets shall at all times remain in such company, and no eligible employee shall have any property interest in any specific assets of such company. Nothing in the Plan and no action taken pursuant to the provisions of the Plan shall be deemed to create a trust or fund of any kind or to create a fiduciary relationship. The obligation to make payments under this Plan shall be and remain an unsecured, unfunded general obligation of the Participating Employer. 3 ARTICLE 9 ADMINISTRATION -------------- The Plan shall be administered by the Committee appointed pursuant to the provisions of Section 14.1 of the Qualified Plan. The Committee shall have the same powers and duties, and shall be subject to the same limitations, as are described in the Qualified Plan. ARTICLE 10 AMENDMENT AND TERMINATION ------------------------- The Plan shall be subject to the same reserved power of amendment and termination as the Qualified Plan. ARTICLE 11 MISCELLANEOUS ------------- Section 11.1 Benefits Non-Assignable. This Plan shall be subject to the same terms as specified in Section 11.6 of the Qualified Plan, and said Section is hereby incorporated by reference. Section 11.2 No Employment Rights. Nothing contained in the Plan and no action taken pursuant to the provisions of the Plan shall be construed as a contract of employment between an employee and the Company or a Participating Employer, or as a right of any employee to be continued in the employment of the Company or a Participating Employer, or as a limitation of the right of the Company or a Participating Employer to discharge any employee at any time, with or without cause, or as a limitation of the right of the employee to terminate employment at any time. Section 11.3 Law Applicable. This Plan and all actions hereunder shall be governed by and construed according to the laws of the State of Michigan. 4 Section 11.4 Legal Fees and Expenses. The Company shall pay all legal fees and expenses that any eligible employee may incur as a result of the Company contesting the validity, enforceability, or such employee's interpretation of, or determinations under this Plan. Section 11.5 Cause. Cause shall mean repeated material breaches of an Employee's duties of employment which are not cured after receipt by the Employee of written notice specifying such breaches or the Employee's conviction of a felony involving moral turpitude. ARTICLE 12 CHANGE IN CONTROL PROVISIONS ---------------------------- Section 12.1 General. In the event of a Change in Control, as defined in Section 12.5, then, notwithstanding any other provision of the Plan, the provisions of this Section 12 shall be applicable and shall supersede any conflicting provisions of the Plan. Section 12.2 Transfer to Rabbi Trust. MCN Corporation ("MCN") has established a trust pursuant to a Trust Agreement dated January 3, 1991 (the "Rabbi Trust"). The terms of the Rabbi Trust provide that, in the event of a Change in Control and thereafter, assets are to be transferred to such trust to provide benefits under the Plan. MCN shall make all transfers of funds required by the Rabbi Trust in a timely manner and shall otherwise abide by the terms of the Rabbi Trust. Section 12.3 Joint and Several Liability. Upon and at all times after a Change in Control, the liability under the Plan of MCN and each Affiliated Employer that has adopted the Plan shall be joint and several so that MCN and each such Affiliated Employer shall each be liable for all obligations under the Plan to each employee covered by the Plan, regardless of the corporation by which such employee is employed. Section 12.4 Dispute Procedures. In the event that, upon or at any time subsequent to a Change in Control, a claim for benefits under the Plan of a Participant or distributee who has exhausted the claims and appeals procedures set forth in Section 13.7 of the Qualified Plan is denied in whole or in part, the following additional procedures shall be applicable: (a) Any amount that is not in dispute shall be paid to the Participant or distributee at the time or times provided herein. 5 (b) MCN shall advance to such claimant from time to time such amounts as shall be required to reimburse the claimant for reasonable legal fees, costs and expenses incurred by such claimant in seeking a judicial resolution of his or her claim, including reasonable fees, costs and expenses relating to appeals; provided, however, that MCN shall not be obligated to advance to the claimant any amounts under this Section 12.4(b) unless and until the claimant agrees in writing to repay to MCN, immediately upon the occurrence of a final judicial determination with respect to such dispute, any amount of such fees, costs and expenses that is not awarded to such claimant in a final order of a court of competent jurisdiction. Section 12.5 Definition of Change in Control. A "Change of Control" means: (a) The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (i) the then outstanding shares of common stock of MCN Corporation (the "Outstanding MCN Common Stock") or (ii) the combined voting power of the then outstanding voting securities of MCN Corporation entitled to vote generally in the election of directors (the "Outstanding MCN Voting Securities");
