The Plan 1.1 Establishment and Amendment of the Plan. Michigan Consolidated Gas Company which is also known as MichCon (hereinafter referred to as the "Company") presently maintains an investment and stock ownership plan for the benefit of its Eligible Employees and the Eligible Employees of its participating Affiliated Companies. The plan was last restated effective as of April 1, 1989, and was amended from time to time thereafter. The plan as previously restated established the MichCon Employee Stock Ownership Plan for Union Employees ("ESOP") and incorporated the ESOP into the Michigan Consolidated Gas Company Union Employee's Investment Plan to form the MichCon Investment and Stock Ownership Plan. The plan is hereby further amended and completely restated as set forth herein effective as of January 1, 1989, except as otherwise provided herein or required by law, and shall continue to be known as the "MichCon Investment and Stock Ownership Plan" (the "Plan"). The ESOP provisions of the Plan shall be effective as of April 1, 1989. 1.2 Applicability of the Plan. Except as otherwise specified herein or required by law, the provisions of the Plan as amended and restated herein effective as of January 1, 1989, shall be applicable only with respect to Eligible Employees of an Employer in current employment on or after January 1, 1989, and their beneficiaries. Any person who was covered under the Plan as in effect prior to January 1, 1989, and whose employment terminated under the Plan -1- 7 prior to January 1, 1989, shall continue to have his rights to receive benefits determined under the provisions of the Plan in effect when his employment relationship so terminated. 1.3 Purpose and Type of Plan. The purpose of the Plan is to provide a convenient way for Participants to save on a regular and long-term basis for their retirement income needs; to recognize the contribution made to the Employer's successful operation by its employees and to reward such contribution for those employees who qualify as participants under the terms of the Plan; and to facilitate ownership of MCN Stock by participating Eligible Employees. The non-ESOP portion of the Plan is intended to qualify as a profit-sharing plan and the ESOP portion of the Plan is intended to qualify as a stock bonus and an employee stock ownership plan for purposes of Code sections 401(a), 402, 412, 417, 4975, and related provisions. -2- 8 Article II.

These hours shall be credited to the individual for the computation period or periods in which the period during which no duties are performed occurs, beginning with the first unit of time to which the payment relates. (c) All hours for which back pay, irrespective of mitigation of damages, has been awarded, agreed to, or paid by an Employer or nonparticipating Affiliated Company, with no duplication of credit for hours. These hours shall be credited to the individual for the computation period or periods to which the award or agreement pertains rather than the computation period in which the award, agreement, or payment is made. (d) Except as provided in section 3.7(e) below, eight Hours of Employment per day for each working day that an -19- 25 individual is absent from work without pay for an approved leave of absence, voluntary time, sick time, disciplinary layoff, or Military Service if the individual returns to the employ of an Employer or nonparticipating Affiliated Company within 90 days after the end of such period. These hours shall be credited to the individual for the computation period or periods in which the period during which no duties are performed occurs, beginning with the first such period. (e) Eight Hours of Employment per day for each working day that an individual is absent from work with or without pay because of pregnancy of the individual, birth of a child to the individual, placement of a child with the individual in connection with the adoption of such child by such individual, or caring for such child for a period beginning immediately following such birth or placement. The Company may, in its discretion, request such information from the individual as the Company shall deem relevant in order to verify that an absence is for the reasons described in this subsection (e). Notwithstanding the foregoing, no more than 501 Hours of Employment shall be credited under this subsection (e) on account of any such pregnancy or placement if the individual does not return to the employ of an Employer or participating Affiliated Company within 90 days after the end of the period approved for such absence. Hours credited under this subsection (e) shall be credited to the individual only in the year in which the absence begins if the crediting is necessary to prevent a Break in Service Year for such year; or, in any other case, in the immediately following year; provided, however, that if more than 501 hours are credited under this subsection (e) on account of any -20- 26 such pregnancy or placement, the excess over 501 hours shall be credited to the period or periods to which it relates. Hours of Employment credited under this section 3.7 shall comply with the rules set forth in 29 C.F.R. section 2530.200b-2(b) and (c), which rules are hereby incorporated by reference. 3.8 Employment by Related Entities. If an Employee's employer is a nonparticipating Affiliated Company, any period in which the Employee is employed by the nonparticipating Affiliated Company, while such membership or common control as defined in section 2.1(c) exists, shall be taken into account for purposes of satisfying the eligibility service requirement set forth in section 3.1 and measuring such Employee's Years of Service to the same extent it would have been had such period of employment been employment by an Employer. 3.9 Leased Employees. A person who is not an Employee of an Employer or nonparticipating Affiliated Company and who performs services for an Employer or a nonparticipating Affiliated Company pursuant to an agreement between the Employer or nonparticipating Affiliated Company and a leasing organization shall be considered a "leased employee" if such person performed the services on a substantially full-time basis for a year and the services are of a type historically performed by employees. A person who is considered a "leased employee" of an Employer or nonparticipating Affiliated Company shall not be considered an Employee for purposes of participating in this Plan or receiving any contribution or benefit under this Plan. A leased employee shall be excluded from this Plan regardless of whether the leased employee participates in any plan maintained by the leasing organization. However, if a leased employee participates in the Plan as a result of subsequent employment with an Employer, his previous service as a leased employee shall be counted in calculating his Years of Service. Notwithstanding the preceding provisions of this section 3.9, a leased employee will be -21- 27 included as an Employee for purposes of applying the requirements described in Code section 414(n)(3) and for purposes of determining the number and identity of Highly Compensated Employees. -22- 28 Article IV.

(b) Changes in Allotments. The allotment of Voluntary Deductions and/or Salary Reductions designated by a Participant shall continue in effect, notwithstanding any change in his Compensation Rate, until the Participant shall change such allotment; provided, however, that such allotment shall in no event be less than 1 percent, nor more than the limits of section 4.1(a)(1) and (2), in incremental percentages of 1 percent. -24- 30 A Participant may change his allotment-- (1) prior to August 1, 1991, as of the first day of any Accounting Period, or (2) on or after August 1, 1991, but prior to December 1, 1993, as of the first day of any calendar quarter, or (3) on or after December 1, 1993, as of the first day of any month, by giving written directions to his Employer in the form prescribed by the Company at least 20 days prior to the effective date of the change. Prior to August 1, 1991, such changes may be made only once in each calendar year, except that any time a Participant's Compensation Rate is changed he shall have the right to change his allotment as of the first day of any Accounting Period commencing not more than 60 days thereafter by giving 20 days' written notice to his Employer in the form prescribed by the Company. (c) Voluntary Suspension of Allotments. Any Participant may, by giving 20 days' written notice to his Employer in the form prescribed by the Company, suspend his allotment of Voluntary Deductions and/or Salary Reductions, effective as of the end of any Accounting Period, either indefinitely or for any specified period provided that in either case the suspension shall be for at least 12 full Accounting Periods. In case of any such suspension of any allotments, the Employer's contributions on behalf of the Participant shall be automatically suspended for a like period. (d) Automatic Suspension of Allotments. A Participant's allotments of Voluntary Deductions and Salary Reductions and the Employer's contributions on behalf of the Participant shall be suspended automatically for any period during which the Participant is absent without pay under any of the circumstances described in section 3.7(c), (d), or (e), and such an absence shall not constitute termination of service for purposes of -25- 31 any of the provisions of Article IX. A Participant may, by giving 20 days' written notice to his Employer in the form prescribed by the Company, suspend his allotment of Voluntary Deductions and/or Salary Reductions for any period during which he is absent from work under any of the circumstances described in section 3.7(b) or (c) and receiving Compensation at a reduced Compensation Rate, in which case the Employer contributions on behalf of such Participant shall be automatically suspended for a like period. 4.2 Employer Investment Plan Contributions. Each Employer shall contribute, to the Salary Reduction Account of each of its participating Employees, an amount equal to 25 percent of the Salary Reduction allotment of such Participant; provided, however, that Salary Reduction allotments shall be disregarded to the extent that they exceed an amount determined by multiplying the applicable contribution percentage shown in the following schedules by the Participant's Compensation Rate: (a) Effective for periods prior to April 1, 1989 for Participants represented by S.E.I.U. Local 80 (Detroit and P.T. & S.) and I.C.W.U.

The maximum Employer matching contributions on behalf of any Participant shall not be increased until such Participant has filed a new election form with the Company. Notwithstanding the foregoing, until January 1, 1990, the Employer contributions on behalf of the Participants represented by I.C.W.U. Locals 70, 132, and 799 (Northern) shall be determined by substituting "100 percent" for "25 percent" in each place that it appears in this section 4.2. -27- 33 The Employer contributions pursuant to this section 4.2 (including the amount of any Salary Reduction allotments made by Participants) shall be made only from the current profits or retained earnings of the Employer. The current profits and accumulated retained earnings of the Employer shall be determined in accordance with generally accepted accounting principles and practices and shall be the amounts reflected in the Employer's certified financial statements. 4.3 Employer ESOP Contributions. (a) Basic ESOP Contribution. Subject to subsection (d) of this section, effective on and after April 1, 1989, each Employer shall contribute to the ESOP Account of each of its participating Employees each pay period an amount equal to the difference, if any, between (1) and (2) below: (1) 75 percent of the sum of the Salary Reduction and Voluntary Deduction allotments of such Participant for such pay period; provided, however, that Salary Reduction and Voluntary Deduction allotments shall be disregarded to the extent that they exceed, in the aggregate, an amount determined by multiplying the applicable contribution percentage in the schedules set forth in section 4.2 by such Participant Compensation Rate. (2) The value of the shares of MCN Stock allocated to the ESOP Account of such Participant pursuant to section 13.4(d) for such pay period. The value of shares allocated under section 13.4(d) shall be the market value thereof as of the last day of the pay period for which the shares are allocated, with the market value to be determined by the Company in a nondiscriminatory manner. (b) Contribution of Principal, Interest, or Other Payments. Each Employer also shall contribute to the ESOP its proportionate share of any additional amount necessary -28- 34 to make principal, interest, or other payments required by the terms of any loan made to the ESOP in accordance with section 13.4. Each Employer's proportionate share shall be equal to the proportion that its contributions under section 4.3(a) bears to the total contributions under section 4.3(a). Effective November 1, 1989, each Employer also may make additional contributions to make principal, interest, or other payments in accordance with the terms of any loan made to the ESOP in accordance with section 13.4.

Effective November 1, 1989, each Employer also shall contribute to the ESOP Account of each of its participating Employees such amounts as may be necessary to acquire for the ESOP Account of such Participant shares of MCN Stock having a fair market value equal to the amount of any dividends on shares of MCN Stock allocated to the ESOP Account of such Participant that were used to repay an ESOP loan in accordance with section 13.4(c). Such contributions shall be made on, or as soon as practicable after, each date on which dividends on allocated shares of MCN Stock are used to repay a loan. In no event shall the shares of MCN Stock acquired with contributions under this subsection (c) be allocated to the ESOP Account of such Participant later than the last day of the Plan Year during which (but for the use of the dividend to repay the loan) the dividend giving rise to such contribution would have been allocated to the ESOP Account of such Participant. (d) Exception. Notwithstanding any other provision hereof, no contributions shall be made prior to January 1, 1990 to the ESOP Account of any Participant represented by I.C.W.U. Locals 70, 132, and 799 (Northern). -29- 35 4.4 Additional Employer Contributions. Effective January 14, 1991, if a Participant receiving payments (based upon 40 or more hours per week) under the terms of any Workers' Compensation law does not have sufficient compensation to make Salary Reduction or Voluntary Deduction allotments in an amount equal to the amount of the Participant's allotments as in effect during the Participant's last period of active service, then the Participant's Employer shall contribute on behalf of the Participant such additional amount as would have been contributed by the Employer under sections 4.2 and 4.3 on behalf of such Participant had the Participant's allotments been continued at the rate in effect during the Participant's last period of active service. Additional contributions under this section 4.4 shall be treated for accounting purposes as if made under section 4.2 or 4.3, as applicable. 4.5 Rollover Contributions. (a) From Qualified Plan. If an Employee receives, either before or after becoming an Employee-- (1) prior to January 1, 1993, a qualified total distribution (within the meaning of Code section 402(a)(5)(E)) or, (2) effective January 1, 1993, an eligible rollover distribution (within the meaning of Code section 402(c)(4)) from an employees' trust described in Code section 401(a) which is exempt from tax under Code section 501(a) or from a qualified annuity plan described in Code section 403(a) (other than an employees' trust or an annuity plan under which the Employee was an Employee within the meaning of Code section 401(c)(1) at the time contributions were made on his behalf under such trust or annuity plan), then such Employee may transfer and deliver to the Company, to be credited to his Employee Salary Reduction Account as if it were a Salary Reduction allotment, an amount which does not exceed the amount of such qualified total distribution -30- 36 or eligible rollover distribution (including any proceeds from the sale of any property received as a part of such qualified total distribution or eligible rollover distribution) less, in the case of a qualified total distribution, the amount considered contributed to such trust or annuity plan by the Employee. (b) From Individual Retirement Account or Annuity. If-- (1) an Employee receives, either before or after becoming an Employee, a distribution or distributions from an individual retirement account or individual retirement annuity (within the meaning of Code section 408) or from a retirement bond (within the meaning of Code section 409); (2) no amount in such account, no part of the value of such annuity, or no part of the value of the proceeds of such bond is attributable to any source other than-- (A) prior to January 1, 1993, a qualified total distribution (within the meaning of Code section 402(a)(5)(E)), or (B) effective January 1, 1993, an eligible rollover distribution (within the meaning of Code section 402(c)(4)) from an employees' trust described in Code section 401(a) which is exempt from tax under Code section 501(a) or annuity plan described in Code section 403(a) (other than an employees' trust or an annuity plan under which the Employee was an Employee within the meaning of Code section 401(c) at the time contributions were made on his behalf under such trust or annuity plan) and any earnings on such a qualified total distribution or eligible rollover distribution; and -31- 37 (3) for rollovers prior to January 1, 1993, the amount received represents the entire amount in such account, the entire value of such annuity or the entire value of such bond, then such Employee may transfer and deliver to the Company, to be credited to his Salary Reduction Account as if it were a Salary Reduction allotment, such distribution or distributions. (c) Timing and Substantiation. Any transfer and delivery pursuant to this section 4.5 shall be delivered by the Employee to the Company and by the Company to the Trustee on or before the sixtieth day after the day on which the Employee receives the distribution or on or before such later date as may be prescribed by law. Any such transfer and delivery must be accompanied by-- (1) a statement of the Employee that to the best of his knowledge the amount so transferred meets the conditions specified in this section 4.5, and (2) a copy of such documents as may have been received by the Employee advising him of the amount and the character of such distribution. Notwithstanding the foregoing, the Company shall not accept a rollover contribution if, in its judgment, such acceptance would cause the Plan to violate any provision of the Code or Regulations. (d) Deemed Allotment for Certain Purposes. A rollover contribution pursuant to this section 4.5 shall be deemed to be an allotment of a Participant for purposes of the value of a Participant's fund account as provided in section 8.2 and in determining the amount distributable to a Participant, the provisions of Article IX that are applicable to Salary Reduction allotments will be used, pursuant to section 9.1, but not for purposes of determining the amount of the contribution to be made on behalf of a Participant by his Employer pursuant to section 4.2, 4.3, or 4.4 or calculating the Annual Addition of such Participant. -32- 38 (e) Deemed Participation for Certain Purposes. If the amount of rollover contribution is made by an Employee prior to his becoming a Participant, such Employee shall, until such time as he becomes a Participant, be deemed to be a Participant for all purposes of the Plan except for purposes of any determination of when he becomes a Participant pursuant to section 3.1 and the making of allotments pursuant to section 4.1(a). 4.6 Transfers from the MichCon Savings and Stock Ownership Plan. Effective January 14, 1991, if an Employee who previously had participated in the MichCon Savings and Stock Ownership Plan (the "Savings Plan") becomes a Participant in the Plan and the Participant's plan account in the Savings Plan is transferred to the Plan in accordance with section 3.3 of the Savings Plan, the Plan shall accept such transfer. Amounts transferred shall be 100 percent vested at all times and shall be treated for all purposes in the same manner as they were treated under the Savings Plan; that is: (a) Amounts attributable to Employer salary reduction allotments under the Savings Plan shall be allocated to the Participant's Employee Salary Reduction Account; (b) Amounts attributable to voluntary deduction allotments under the Savings Plan shall be allocated to the Participant's Employee Voluntary Deduction Account; (c) Amounts attributable to Employer Savings Plan contributions shall be allocated to the Participant's Employer Salary Reduction Account or Employer Voluntary Deduction Account, as the case may be; and (d) Amounts transferred from the ESOP Account of the Participant in the Savings Plan shall be allocated to the Participant's ESOP Account. Notwithstanding the foregoing, amounts transferred shall not be used for purposes of determining the amount of the contribution to be made on behalf of a Participant by the Employer pursuant to section 4.2, 4.3, or 4.4, or calculating the Actual Deferral Percentage or Annual Addition of the Participant. -33- 39 4.7 Transfers from the MichCon Employee Stock Ownership Plan. (a) In General. The Company has previously maintained the MichCon Employee Stock Ownership Plan (the "Tax Credit ESOP"), which was a plan separate and distinct from the MichCon Employee Stock Ownership Plan for Union Employees which constitutes a part of the Plan. The Company terminated the Tax Credit ESOP and, upon such termination, a portion of the assets of the Tax Credit ESOP were transferred to this Plan. The purpose of this section 4.7, which is effective as of January_25, 1991, is to set forth specific provisions applicable to the assets so transferred. In the event of any conflict between any other provision of the Plan and this section 4.7 the terms of this section 4.7 shall govern with respect to amounts transferred from the Tax Credit ESOP, adjusted for earnings and losses thereon. (b) Allocation to ESOP Account. All amounts transferred from the Tax Credit ESOP attributable to Plan Years 1975 through 1982 on behalf of any Participant or former Participant who has an account balance in this Plan shall be allocated to the ESOP Account of such Participant or former Participant. The amounts transferred to the ESOP Account of a Participant or former Participant, adjusted for any earnings or losses thereon, shall, subject to the special rules set forth in this section 4.7, be treated in the same manner as other assets of the ESOP Accounts for all purposes of this Plan, including, but not limited to, distributions, loans, investments, and diversification of investments. The amounts transferred shall not be deemed to constitute an Employee Allotment or an Employer Contribution for discrimination testing or any other purpose. (c) Allocation to MCN Salary Reduction Account. All amounts transferred from the Tax Credit ESOP -34- 40 attributable to Plan Years 1983 through 1986 on behalf of any Participant or former Participant who has an account balance in this Plan shall be allocated to the Salary Reduction Account of such Participant or former Participant. The amounts transferred to the Salary Reduction Account of a Participant or former Participant, adjusted for any earnings or losses thereon, shall, subject to the special rules set forth in this section 4.7, be treated in the same manner as other assets of the Salary Reduction Accounts for all purposes of this Plan, including, but not limited to, distributions, loans, investments, and diversification of investments. The amounts transferred shall not be deemed to constitute an Employee Allotment or an Employer Contribution for discrimination testing or any other purpose. (d) Vesting. All amounts transferred from the Tax Credit ESOP on behalf of any Participant or former Participant, adjusted for any earnings or losses thereon, shall at all times be fully vested and nonforfeitable. 4.8 Limitations on Salary Reduction Allotments. (a) Dollar Limitation. In no event shall any Employer make Salary Reduction allotments for any calendar year, with respect to any Participant in excess of $7,627 (for 1989) (as adjusted by the Secretary of the Treasury to reflect increases in the cost of living). This limit shall be applied by aggregating all plans and arrangements maintained by the Company and all Affiliated Companies that provide for elective deferrals (as defined in Code section 402(g)). (b) ADP Test. Effective for Plan Years beginning on or after January 1, 1992, in addition to the limitations set forth elsewhere in this Plan, one of the following tests must be satisfied for the Plan Year: -35- 41 (1) The Average Actual Deferral Percentage for Highly Compensated Employees who are eligible to participate for the Plan Year shall not exceed the Average Actual Deferral Percentage for Nonhighly Compensated Employees who are eligible to participate for the Plan Year multiplied by 1.25; or (2) The Average Actual Deferral Percentage for Highly Compensated Employees who are eligible to participate for the Plan Year shall not exceed the Average Actual Deferral Percentage for Nonhighly Compensated Employees who are eligible to participate for the Plan Year multiplied by two, provided that the Average Actual Deferral Percentage for such Highly Compensated Employees does not exceed the Average Actual Deferral Percentage for such Nonhighly Compensated Employees by more than two percentage points. (c) Determination of Actual Deferral Percentages. For purposes of the Actual Deferral Percentage test described in this section 4.8-- (1) An Elective Deferral will be taken into account for a Plan Year only if it relates to Compensation that either would have been received by the Eligible Employee in the Plan Year (but for the deferral election) or is attributable to services performed by the Eligible Employee in the Plan Year and would have been received by the Eligible Employee within 2_1/2 months after the close of the Plan Year (but for the deferral election); (2) An Elective Deferral will be taken into account for a Plan Year only if it is allocated to the Eligible Employee as of a date within that Plan Year. For this purpose, an Elective Deferral is considered allocated as of a date within a Plan Year if the allocation is not contingent on -36- 42 participation or performance of services after such date and the Elective Deferral is actually paid to the Trust no later than 12 months after the Plan Year to which the contribution relates; (3) The Actual Deferral Percentage for an Employee who is eligible to participate shall be computed by treating any Excess Deferral (as defined in section 4.9) as an Elective Deferral, except to the extent provided by Regulations; (4) The Actual Deferral Percentage for any Employee who is a participant under two or more section 401(k) plans or arrangements that are maintained by the Company or an Affiliated Company shall be determined as if all such Elective Deferrals were made under a single arrangement; provided, however, that no Elective Deferrals under an employee stock ownership plan (as defined in Code section 4975(e)(7)) shall be taken into account for purposes of this section 4.8; (5) In the event that two or more plans which include cash-or-deferred arrangements are considered as one plan for purposes of Code section 401(a)(4) or 410(b), the cash-or-deferred arrangements included in such plans shall be treated as one arrangement for purposes of this section 4.8; (6) For purposes of determining the Actual Deferral Percentage of an Employee who is a 5-percent owner of the Company or one of the ten Highly Compensated Employees paid the most Compensation during the year, the Elective Deferrals and Compensation of such Employee shall include the Elective Deferrals and Compensation of Family Members, and such Family Members shall be disregarded in determining the Actual Deferral Percentage for Employees who are Nonhighly Compensated Employees; and -37- 43 (7) The determination and treatment of the Elective Deferrals and Actual Deferral Percentage of any Employee shall satisfy such other requirements as may be prescribed by the Secretary of Treasury. 4.9 Distribution of Excess Deferrals. "Excess Deferrals" means excess deferrals as defined under Code section 402(g). Notwithstanding any other provision of the Plan, the Excess Deferral, if any, of each Employee with respect to a calendar year plus any income and minus any loss allocable thereto shall be distributed no later than April 15 of the following calendar year to each Employee who claims an Excess Deferral for the preceding calendar year. Excess Deferrals shall be treated as Annual Additions under the Plan. The Employee's claim shall be in writing; shall be submitted to the Company no later than March 1; shall specify the Employee's Excess Deferral for the preceding calendar year; and shall be accompanied by the Employee's written statement that if such amount is not distributed, such Excess Deferral, when added to amounts deferred under other plans or arrangements described in Code section 401(k), 408(k), or 403(b), exceeds the limit imposed on the Employee by Code section 402(g) for the year in which the deferral occurred. Notwithstanding the preceding paragraph, the Employer may notify the Plan on behalf of the individual of Excess Deferrals to the extent that the individual has Excess Deferrals for the calendar year calculated by taking into account only elective deferrals under this Plan and other plans of the Company and any Affiliated Company. The Excess Deferral distributed to an Employee with respect to a calendar year shall be adjusted for any income or loss thereon for such calendar year and for the period between the end of such calendar year and the date of distribution. The income or loss allocable to such calendar year shall be determined by -38- 44 multiplying the income or loss for such calendar year allocable to the Employee's Salary Reduction Account by a fraction, the numerator of which is the Excess Deferral of the Employee for such calendar year and the denominator of which is the Employee's Salary Reduction Account balance on the last day of such calendar year. The income or loss allocable to the period between the end of such calendar year and the date of distribution shall be equal to 10 percent of the income or loss allocable to the Excess Deferral for the preceding calendar year multiplied by the number of calendar months that have elapsed from the end of the preceding calendar year to the date of distribution. A distribution occurring on or before the fifteenth day of the month shall be treated as having been made on the last day of the preceding month and a distribution occurring after such fifteenth day shall be treated as having been made on the first day of the following month. In the event that an Employee's Salary Reduction allotments are distributed to such Employee under this section 4.9, any Employer contributions attributable thereto plus any income and minus any loss allocable thereto shall be forfeited. 4.10 Distribution or Recharacterization of Excess Contributions. (a) Determination of Excess Contributions. "Excess Contributions" means, with respect to any Plan Year, the excess of-- (1) the aggregate amount of Elective Deferrals actually paid over to the Trust on behalf of Highly Compensated Employees for such Plan Year, over (2) the maximum amount of such Elective Deferrals permitted under the limitations of section 4.8(b), determined by reducing Elective Deferrals as follows: (A) First, the Actual Deferral Percentage (as defined in section 2.1(b)) of the Highly -39- 45 Compensated Employee with the highest Actual Deferral Percentage is reduced to the extent necessary to satisfy the test described in section 4.8(b) or to cause such percentage to equal the Actual Deferral Percentage of the Highly Compensated Employee with the next highest Actual Deferral Percentage. (B) Second, this process is repeated until the test described in section 4.8(b) is satisfied. Excess Contributions shall be treated as Annual Additions under the Plan. For purposes of this section 4.10, to the extent permitted by the Code, the Excess Contributions shall be reduced by the amount of any Excess Deferrals included in such Excess Contributions and distributed to the Employee pursuant to section 4.9. (b) Distribution or Recharacterization. Notwithstanding any other provision of the Plan, either-- (1) Excess Contributions with respect to a calendar year plus any income and minus any loss allocable thereto shall be distributed no later than the last day of the following calendar year to Employees on whose behalf such Excess Contributions were made for the preceding calendar year; or (2) at the election of the Employee and to the extent permitted by the Code, the Excess Contributions shall be treated as distributed to the Employee and then contributed by the Employee to the Plan as a Voluntary Deduction allotment. (c) Adjustment for Income and Loss. The Excess Contributions to be distributed to an Employee with respect to a calendar year shall be adjusted for any income or loss thereon for such calendar year and for the period between the end of such calendar year and -40- 46 the date of distribution. The income or loss allocable to such calendar year shall be determined by multiplying the income or loss for such calendar year allocable to the Employee's Salary Reduction Account by a fraction, the numerator of which is the Excess Contributions for such calendar year and the denominator of which is the Employee's Salary Reduction Account balance on the last day of such calendar year. The income or loss allocable to the period between the end of such calendar year and the date of distribution shall be equal to 10 percent of the income or loss allocable to the Excess Contributions for the preceding calendar year multiplied by the number of calendar months that have elapsed from the end of the preceding calendar year to the date of distribution. A distribution occurring on or before the fifteenth day of the month shall be treated as having been made on the last day of the preceding month and a distribution occurring after such fifteenth day shall be treated as having been made on the first day of the following month. In the event that an Employee's Salary Reduction allotments are distributed to such Employee under this section 4.10, any Employer contributions attributable thereto plus any income and minus any loss allocable thereto shall be forfeited. 4.11 Statutory (Code Section 415) Limitations on Allocations to Accounts. Notwithstanding any other provision of the Plan, contributions under the Plan shall be subject to the limitations set forth in Code section 415, which are incorporated herein by reference. For purposes of applying such limitations to contributions under the Plan, the rules set forth in this section 4.11 shall be applicable. -41- 47 (a) Annual Addition. The term "Annual Addition" means the amount allocated to a Participant's account during any calendar year that constitutes-- (1) Employer contributions; (2) Employee contributions; (3) forfeitures; and (4) amounts described in Code sections 415(l)(1) and 419A(d)(2). The compensation limitation referred to in Code section 415(c)(1)(B) shall not apply to-- (A) any contribution for medical benefits (within the meaning of Code section 419A(f)(2)) after separation from service which is otherwise treated as an Annual Addition, or (B) any amount otherwise treated as an Annual Addition under Code section 415(l)(1). The Annual Addition for any calendar year before 1987 shall not be recomputed to treat all Employee contributions as an Annual Addition. (b) Combined-Plan Limits. In the case of an individual who was a Participant in the Plan on December 31, 1986, an amount shall be subtracted from the numerator of the defined contribution fraction (not exceeding such numerator) as prescribed by the Secretary of Treasury so that the sum of the defined benefit plan fraction and defined contribution plan fraction does not exceed 1.0 as of such date. Code section 415 shall be applied in such manner as to maximize the permissible contributions and benefits thereunder and, in determining the permissible amount of contributions under the Plan, any grandfathering provisions heretofore or hereafter adopted pursuant to Code section 415 shall be applicable. For purposes of applying the limitations set forth in Code section 415(e), the Michigan Consolidated Gas Company -42- 48 Retirement Plan For Employees Covered By Collective Bargaining Agreement shall be the primary plan and any required reductions shall be made in the Annual Additions to this Plan. (c) Reduction of Annual Additions. (1) If the limitations of Code section 415 would be exceeded as a result of a reasonable error in estimating a Participant's compensation or on account of such other limited facts and circumstances as the Commissioner of Internal Revenue finds justify the application of the rules hereinafter set forth, the Annual Additions to the Participant's account which exceed the applicable limitation shall be returned to the Participant to the extent of all or any portion of any Voluntary Deduction allotments which were made by him pursuant to Article IV. Any net earnings and gains allocable to such allotments for the period between the date of such allotment and the date returned shall also be repaid to the Participant but such return of net earnings and gains will not be deemed a further reduction of any excess Annual Additions. (2) If the Participant made no Voluntary Deduction allotments or if, after returning all or part of such allotments in accordance with the previous paragraph, his Annual Additions still exceed the limitations of Code section 415, then such excess shall be returned to the Participant to the extent of all or any portion of any Salary Reduction allotments made on behalf of such Participant, together with any net earnings and gains on such allotments as hereinabove described. (3) If, after returning all or any portion of Voluntary Deduction and Salary Reduction allotments of a Participant in accordance with the preceding paragraphs, his Annual Additions still -43- 49 exceed the limitations of Code section 415, such portion of the Employer contributions under section 4.2 made on behalf of the Participant as must be removed to meet the limitations shall be allocated and reallocated to other Participants' Investment Plan Accounts as contributions by the Employer. (4) If, after reallocating all or any portion of Employer contributions under section 4.2, a Participant's Annual Additions still exceed the limitation of Code section 415, such portion of the Employer contributions under section 4.3(a) made on behalf of the Participant and shares of MCN Stock allocated to his ESOP Account under section 13.4(d) as must be removed to meet the limitations shall be allocated and reallocated to other Participant's ESOP Accounts as contributions by the Employer. (5) If, as a result of the allocation of forfeitures, a reasonable error in estimating a Participant's Compensation, or under other limited facts and circumstances which the Commissioner of the Internal Revenue Service finds justify the availability of the following rules, any amount cannot be allocated during the Plan Year in accordance with the foregoing procedure without exceeding the applicable limitations for one or more Participants, any remaining amount shall be held unallocated in a special suspense account to be allocated to Participants in the succeeding Plan Year or Plan Years; provided, however, that (A) no Employer contributions and no Voluntary Deduction allotments shall be made in such succeeding Plan Year or Plan Years until such special suspense account is exhausted by allocations and reallocations; (B) no investment gains (or losses) or other income shall be -44- 50 allocated to the special suspense account; and (C) the amounts in the special suspense account shall be allocated as soon as possible without violating the limitations of this section 4.11. -45- 51 Article V. Vesting in Accounts 5.1 Employee Salary Reduction Accounts, Employee Post-1986 Voluntary Deduction Account, and Employee Pre-1987 Voluntary Deduction Account. The Employee Salary Reduction Account, the Employee Post-1986 Voluntary Deduction Account, and the Employee Pre-1987 Voluntary Deduction Account of each Participant shall be fully vested and nonforfeitable at all times. 5.2 Employer Salary Reduction Account, Employer Voluntary Deduction Account, and ESOP Account. (a) In General. A Participant shall have a vested and nonforfeitable interest in his Employer Salary Reduction Account, Employer Voluntary Reduction Account, and ESOP Account after he has completed at least five Years of Service. Prior to that time he shall have no vested interest in such accounts. (b) Accelerated Vesting. Notwithstanding section 5.2(a) above, a Participant shall be fully vested and have a nonforfeitable interest in his entire Employer Salary Reduction Account, Employer Voluntary Deduction Account, and ESOP Account if-- (1) while still an Employee, he attains age 65; (2) while still an Employee, he dies or suffers a total and permanent disability as defined in section 2.1(l); or (3) while he is an Employee, contributions to the Plan are completely discontinued or the Plan is terminated, or the Plan is partially terminated and such Participant is affected by such partial termination. -46- 52 Article VI. Investment Provisions 6.1 Investment of Contributions and Allotments. Employer contributions under sections 4.2, 4.3, and 4.4 and Employee allotments shall be invested in accordance with the following provisions: (a) The Employer contributions made pursuant to section 4.3(a) and (c) shall be invested in the MCN Stock fund, which fund is described in Article VII. (b) Each Participant shall, by written direction to the Company in the form prescribed by the Company, direct that the Employer contributions made pursuant to section 4.2 and Employee allotments, including those made as a Salary Reduction, be invested in such funds offered by the Trustee as are selected by the Company. Employee allotments, including those made as a Salary Reduction, and the portion of Employer contributions referenced in section 6.1(b) above, need not be invested in the same fund. A Participant shall direct the manner in which the total of such allotments and such Employer contributions referenced in section 6.1(b) above shall be divided, equally or otherwise, among the funds. With respect to any Employee who is a Participant on April 1, 1989 and who has not filed a new election form to direct Employer contributions in accordance with this section 6.1, Employer contributions under section 4.3(a) and (c) shall automatically be directed to the MCN Stock fund and Employer contributions under section 4.2 shall automatically be directed to the Fixed Income fund. 6.2 Change of Investment Direction. Any investment direction given by a Participant under section 6.1 shall be deemed to be a continuing direction until changed by the Participant. A Participant may change any such direction in accordance with such procedures as the Company may from time to time provide and apply in a nondiscriminatory manner. -47- 53 6.3 Transfers Between Investment Funds. A Participant may direct that all or any part of the value of his interest in any investment fund be transferred to one or more of the other funds except that a Participant may not transfer any amount from the MCN Stock fund to the extent that the balance remaining in such fund immediately after the transfer would be less than the value of his ESOP Account. Notwithstanding the foregoing, no transfers may be made to the Primark Corporation Stock fund by a Participant. A transfer of all or any part of the value of a Participant's interest in the Fixed Income fund may from time to time be restricted by the terms of agreements which govern the investment of assets in such fund, in which event the Company shall give notice of such restrictions to the Participants. Prior to September 1, 1991, transfers between funds shall be effected only as of the first day of any Accounting Period upon written directions to the Company in the form prescribed by the Company given at least 20 days prior to the effective date of such transfer. Prior to September 1, 1991, if a Participant shall direct the transfer of all or any part of the value of his interest in a fund, the Participant shall not be allowed to direct transfers to such fund for a period of one year from the date of such transfer. Prior to April 30, 1991, the procedures set forth above were equally applicable to the Primark Corporation Stock fund. After that date, such fund ceased to exist. -48- 54 Article VII. Investment Funds 7.1 Investment Funds. The Trustee shall establish, operate, and maintain the following funds exclusively for the collective investment and reinvestment of monies directed by the Company to be invested in such funds on behalf of Participants: (a) MCN Stock Fund.

A Fixed Income fund which shall be invested, except as hereinafter provided, in accounts or, effective as of December 18, 1992, in marketable fixed income securities or accounts maintained by financial institutions which provide for fixed or variable rates of interest for specified periods of time. The terms of such agreements and the selection of such institutions shall be determined by the Company. Investment advisors for marketable fixed income securities may use fixed income futures and options to reduce the effect of market volatility. (c) Primark Corporation Stock Fund. Until April 30, 1991, a Primark Corporation Stock Fund to be invested in accordance with the terms of this paragraph (e).

As soon as practicable after April 12, 1991, the shares of Primark Corporation Stock in the fund shall be sold and the proceeds of such sales shall be invested solely in any short-term fixed income fund described in section 8.1. As of May 1, 1991 (or, if the sale of all shares of Primark Corporation Stock is not completed by April 30, 1991, then June 1, 1991), the assets of the fund shall be transferred to the MCN Stock Fund and the Primark Corporation Stock Fund shall cease to exist. Each Participant shall be entitled to direct the transfer of all or any portion of the amounts so -49- 55 transferred to the MCN Stock Fund on his or her behalf to any other fund or funds in accordance with, and subject to the limitations of section 7.3. (d) Other Funds. Such other funds offered by the Trustee as the Company may select. Notwithstanding the foregoing, the Trustee or the investment manager, as the case may be, shall invest such portion of the assets of the funds as the Company may deem necessary or appropriate to facilitate the administration of such funds in any short-term fixed income fund as may be established under any common, commingled, or collective trust for employee benefit plans established and maintained by the Trustee. 7.2 Management of Investment Funds. Except as otherwise provided in this Article VII, each fund shall be under the exclusive management and control of the Trustee; the ownership of the assets and investments of the funds shall be in the Trustee as such; and the Trustee shall have in respect of any and all assets of the funds the same powers as if it were absolute owner thereof. 7.3 Voting of MCN Stock. (a) Instructions from Participants. The Trustee shall vote, in person or by proxy, shares of MCN Stock held by the Trustee in the MCN Stock fund in accordance with instructions obtained from Participants. Each Participant shall be entitled to give voting instructions with respect to the number of shares of such respective stock which bears the same ratio to the total number of shares held by the Trustee on the record date as the number of shares allocated to the respective stock fund account of such Participant as of the Valuation Date preceding such record date bears to the total number of shares allocated to the respective stock fund accounts of all Participants as of such -50- 56 Valuation Date, excluding shares allocated to the accounts of persons whose accounts have been distributed prior to such record date. Written notice of any meeting of stockholders of MCN Corporation and a request for voting instructions shall be given by the Company or the Trustee, at such time and in such manner as the Company shall determine, to each Participant entitled to give instructions for the voting of stock at such meeting. Shares with respect to which no voting instructions are received from Participants and unallocated shares of the ESOP shall be voted by the Trustee in the same proportion as shares for which voting instructions are received from Participants. The Trustee shall combine and vote fractional shares to the extent possible to reflect the voting instructions of Participants. (b) Confidentiality. The instructions received by the Trustee from Participants shall be held by the Trustee in strict confidence and shall not be divulged or released to any person, including officers or employees of the Company or any Affiliated Company. 7.4 Tender Offers.

Each Participant shall have the right, to -51- 57 the extent the terms of the tender offer so permit, to direct the withdrawal of such shares from tender. A Participant shall not be limited as to the number of instructions to tender or withdraw from tender which he can give; provided, however, the Participant shall not have the right to give instructions to tender or withdraw from tender after a reasonable time established by the Trustee pursuant to section 7.4(c) below. (b) Duties of the Company. Within a reasonable time after the commencement of a tender offer, the Company shall provide to each Participant having an ownership interest in the MCN Stock fund-- (1) the offer to purchase as distributed by the offeror to the shareholders of MCN Corporation, (2) a statement of the shares representing his interest in the MCN Stock fund as of the most recent information available from the Company, and (3) directions as to the means by which a Participant can give confidential instructions to the Trustee with respect to the tender. The Company shall establish and pay for a means such as, but not limited to, Datagram by which a Participant can expeditiously deliver to the Trustee instructions with respect to the tender. (c) Duties of the Trustee. The Trustee shall follow the instructions of the Participants with respect to the tender offer. The Trustee shall not tender shares for which no instructions are received. Unallocated shares of MCN Stock of the ESOP shall be tendered or exchanged by the Trustee in the same proportion as the allocated shares for which the Trustee has received written direction are tendered or exchanged, subject to the terms of any loan or pledge agreement covering such shares. On the basis of its ability to comply with the -52- 58 terms of the offer, the Trustee shall establish a reasonable time after which it shall not accept the instructions of Participants.

Brokerage commissions, transfer taxes, and other charges and expenses in connection with the purchase and sale of securities for a fund shall be charged to the fund. Any income and other taxes payable with respect to a fund shall likewise be charged to the fund. 7.7 Primark Corporation Stock. The provisions of sections 7.3, 7.4, and 7.5 pertaining to MCN Stock shall also be applicable to Primark Corporation Stock during the period of its existence. -53- 59 Article VIII. Accounts and Records of the Plan 8.1 Company to Maintain Accounts. The Company shall maintain, or cause to be maintained, for each Participant-- (a) an Investment Plan Account attributable to Voluntary Deduction allotments and related Employer contributions under section 4.2, and (b) a separate account attributable to Salary Reduction allotments and related Employer contributions under section 4.2, each of which shall be composed, to the extent required by the investment directions of the particular Participant, of a MCN Stock fund account, a Fixed Income fund account, and an account for each other applicable fund in which his allotments and related contributions are invested.

The Company shall maintain, or cause to be maintained, all necessary records. 8.2 Plan Accounting. The interests of each Participant in the funds shall be his proportionate share of the value of such funds as of any Valuation Date. The Participant's proportionate share may be determined under any accounting method selected by the Company that allocates fairly, in the opinion of the -54- 60 Company, the investment gains and losses by or on behalf of each Participant to the fund and that complies with the Code requirements of the Code and the Regulations thereunder. The value of Participants' fund accounts shall be redetermined as of each Valuation Date. 8.3 Valuation of Funds. The value of a fund as of any Valuation Date shall be the market value of all assets (including any uninvested cash) held by the fund as determined by the Trustee reduced by the amount of any accrued liabilities of the fund on such Valuation Date.

A Trust has been established to fund benefits under the Plan. The Employers may, without further reference to or action by any Employee or Participant, from time to time enter into further agreements with the Trustee and make such amendments to such Trust Agreement or such further agreements as they may deem necessary or desirable to carry out the Plan, and may take such other steps and execute such other instruments as the Employers may deem necessary or desirable to put the Plan into effect or to carry it out. -56- 62 Article IX. Distributions, Withdrawals, and Loans 9.1 Distribution Upon Termination of Employment Entitling Participant to Value of Plan Account. Upon termination of a Participant's employment with his Employer-- (a) due to retirement on his Normal Retirement Date, his Early Retirement Date, or his Disability Retirement Date, (b) by the death of the Participant, (c) because of total and permanent disability or legally established mental incompetency of the Participant not qualifying the Participant for retirement pursuant to section 2.1(l), or (d) under any circumstances after the Participant has satisfied the Vesting Requirement, the Company shall, subject to the provisions of section 9.7, direct the Trustee to distribute to the Participant, or, in a proper case his designated beneficiary or legal representative, the value of the Participant's Plan Account as of the Valuation Date coincident with or next following the date of termination of employment. Notwithstanding the foregoing, the value of a Participant's Plan Account shall become nonforfeitable as of the date on which the Participant attains his sixty-fifth birthday, provided he is an Employee on that date. 9.2 Distribution Upon Termination of Employment Under Circumstances Resulting in Forfeiture of Employer Contributions. Upon termination of a Participant's employment under circumstances other than those described in sections 9.1 and 9.7(c)(2), the Company shall, subject to the provisions of section 9.7, direct the Trustee to distribute to the Participant an amount equal to the value of the Participant's Employee Pre-1987 Voluntary Deduction Account, Employee Post-1986 Voluntary Deduction Account, and Employee Salary Reduction Account each of which shall be fully vested and nonforfeitable at all times. The -57- 63 Participant's Employer Voluntary Deduction Account, Employer Salary Reduction Account, and ESOP Account shall be forfeited and applied in reduction of the next succeeding contribution which the Participant's Employer would otherwise contribute to the Trust; provided, however, if such Participant is reemployed prior to his incurring five consecutive Break in Service Years, then as of the Valuation Date coincident with or next following his date of reemployment, the Participant's Employer shall contribute on behalf of such Participant an amount equal to the amount that was forfeited upon his termination of employment, and such contribution shall be credited to the same accounts from which it was forfeited, in the same amounts, except amounts that would otherwise be credited to the Primark Corporation Stock fund shall be credited to the MCN Stock fund. Such contributions shall not be taken into account in determining under section 4.11 the Annual Additions to such Participant's Savings Plan Account. 9.3 Certain Distributions from Participant Accounts. (a) In General. Any Participant may, upon 20 days' written notice to the Company in the form prescribed by the Company, terminate his participation in the Plan as of any Valuation Date. Upon such termination, the Company shall direct the Trustee to distribute to the Participant an amount equal to the value of the Participant's Employee Pre-1987 Voluntary Deduction Account and Employee Post-1986 Voluntary Deduction Account. Such a Participant shall continue to be considered a Participant for all purposes of the Plan except for purposes of Article IV (Contributions), but shall be ineligible to again elect to make allotments under the Plan for a period of 12 full Accounting Periods from the date of termination of his participation. -58- 64 (b) Withdrawals After Age 59 1/2. (1) Prior to January 25, 1991, upon 20 days' written notice to the Company in the form prescribed by the Company, any Participant who has satisfied the Vesting Requirement and attained age 59 1/2 may terminate his participation in the Plan as of any Valuation Date. Upon such termination, the Company shall direct the Trustee to distribute to the Participant the value of his Plan Account as of such Valuation Date and such Participant shall be ineligible to again elect to make allotments under the Plan for a period of 12 full Accounting Periods from the date of termination of participation. (2) Effective January 25, 1991, upon 20 days' written notice to the Company in the form prescribed by the Company, any Participant who has attained age 59 1/2 may make an election, not more frequently than-- (A) prior to December 1, 1993, once in any 12-month period, or (B) on or after December 1, 1993, once every calendar year, to withdraw all or any portion of the vested amount of his Plan Account as of any Valuation Date. Upon such withdrawal, the Company shall direct the Trustee to distribute to the Participant as of such Valuation Date the amount the Participant has elected to withdraw. (c) Limited Withdrawal in the Event of Hardship. Effective January 25, 1991, if a Participant incurs a financial hardship as defined in section 9.6, he may limit the amount of a distribution from his Voluntary Deduction Account under section 9.3(a) to the amount necessary to satisfy the hardship and to pay any taxes resulting from such distribution. -59- 65 9.4 In-Service Withdrawals--General. At its discretion, the Company may adopt rules limiting the number of withdrawals that may be made in any Plan Year and prescribe a minimum amount that may be withdrawn. All requests for a withdrawal shall be submitted in a form prescribed by the Company. A Participant may not rescind a request for withdrawal which has been submitted to the Company unless the Company consents. A withdrawal shall be distributed as soon as reasonably practicable after the withdrawal request is received. 9.5 Withdrawal of Voluntary Deduction Allotments. Any Participant who shall have actively participated in the Plan for 24 or more calendar months (for purposes of this section 9.5 active participation means the Participant shall have made allotments to the Plan in each month in which compensation was available), may, upon 20 days' written notice to the Company, withdraw as of any Valuation Date an amount not in excess of 100 percent of his Voluntary Deduction allotments under the Plan; provided, however, that the amount withdrawn shall in no event exceed the sum of the values of his Employee Pre-1987 Voluntary Deduction Account and Employee Post-1986 Voluntary Deduction Account invested in the MCN Stock fund, the Fixed Income fund, and any other investment funds under the Plan as of such Valuation Date. Successive withdrawals may be made at intervals of not less than two full years provided that the total amount withdrawn may never exceed the limitations prescribed in the preceding sentence. Withdrawals under this section 9.5 shall be from the MCN Stock fund, the Fixed Income fund, or such other investment funds offered by the Trustee as the Company shall make available for purposes of this section. If the Participant has an account in more than one fund, he shall specify in his written direction to the Company the amount to be withdrawn from each fund. The allotments in all funds in the Employee Pre-1987 Voluntary Deduction Account must be withdrawn before a withdrawal is permitted from a fund in the Employee Post-1986 Voluntary -60- 66 Deduction Account. The amount of an in-service withdrawal from a specific fund in a Voluntary Deduction Account shall not exceed the Employee's allotments in such fund prior to the withdrawal. 9.6 Hardship Withdrawal of Salary Reduction Allotments. A Participant may request, upon 20 days' written notice to the Company, a withdrawal from his Salary Reduction Account if the withdrawal is necessary to satisfy an immediate and heavy financial need of a Participant as defined below. The amount of such withdrawal shall be limited to the Participant's Salary Reduction allotments or the total value of the Participant's Employee Salary Reduction Account as of the latest Valuation Date for which information is available, whichever is smaller. Withdrawals under this section 9.6 shall be from the MCN Stock fund, the Fixed Income fund, or such other investment funds under the Plan as the Participant specifies in his written request for a hardship withdrawal. The determination of whether or not a distribution is necessary to satisfy an immediate and heavy financial need and the amount required to be distributed to meet the need shall be made by the Company. All determinations regarding financial need shall be made in accordance with written procedures established by the Company and applied in a uniform and nondiscriminatory manner. Such written procedures shall specify the requirements for requesting and receiving distributions on account of financial need, including the forms that must be submitted and to whom the forms are to be submitted. All determinations regarding financial need must comply with applicable Regulations under the Code. For purposes of this section 9.6, a financial hardship withdrawal shall be limited to the amount required to meet the need created by one of the following situations: (a) Expenses for medical care described in Code section 213(d) previously incurred by the Participant, his -61- 67 spouse, or any dependents of the Participant or necessary for these persons to obtain medical care described in Code section 213(d). (b) Costs directly related to the purchase (excluding mortgage payments) of the principal residence for the Participant. (c) Payment of tuition and related educational fees for the next 12 months of post-secondary education for the Participant, his spouse, children, or dependents (as defined in Code section 152). (d) The need to prevent the eviction of the Participant from his principal residence or foreclosure on the mortgage on the Participant's principal residence. A distribution will be deemed necessary to satisfy an immediate and heavy financial need of a Participant only if both of the following conditions are met: (1) The distribution is not in excess of the amount of the immediate and heavy financial need of the Participant. Effective January 1, 1993, this amount may be increased by the lesser of the amount withheld from the distribution under Code section 3405(c), as enacted by section 522(b) of the Unemployment Compensation Amendments of 1992, Public Law No. 102-318, Stat. 290 or remaining Salary Reduction allotments or total value of the Salary Reduction Account, if less, after subtracting the amount of the immediate and heavy financial need. (2) The Participant has obtained all distributions, other than hardship distributions, and all loans available under this Plan and all other plans maintained by the Employer. If a Participant receives a hardship distribution, (A) the Participant shall not be entitled to make Salary Reduction allotments or Voluntary Deduction allotments for a period of one year after the hardship distribution, and (B) the Participant may not make Salary Reduction allotments for the Participant's taxable year immediately following the taxable year of the -62- 68 hardship distribution in excess of the amount specified in Code section 402(g) for such taxable year less the amount of the Participant's Salary Reduction allotments for the taxable year of the hardship distribution. 9.7 Time of Distributions. (a) In General. Except as hereinafter provided and subject to the provisions of section 9.9, distributions made pursuant to section 9.1 or 9.7(c)(2) shall be made by the Trustee at the direction of the Company on such date as the Company shall determine after consultation with the Participant or his beneficiary, but in no event later than March 1 of the calendar year following termination of the Participant's employment. Except as hereinafter provided, all other distributions or withdrawals under this Article IX shall be paid as soon as reasonably practicable by the Trustee at the direction of the Company after the applicable Valuation Date. Notwithstanding any other provision of the Plan-- (1) if the vested portion of a Participant's Plan Account exceeds $3,500, no distribution shall be made to such Participant pursuant to section 9.1, 9.2, 9.7(c)(2), or 9.9 prior to the date the Participant attains the age of 65 without written consent of the Participant; and (2) if a distribution to a Participant is deferred pursuant to (1), the amount that would otherwise have been distributed to such Participant shall be invested-- (A) prior to August 1, 1991, in the Fixed Income fund, and (B) on and after August 1, 1991, in the Fixed Income fund or any other investment fund under the Plan, as the Participant shall direct, -63- 69 except that the ESOP Account of such Participant shall continue to be invested in the MCN Stock fund, subject to the diversification rules set forth in section 13.5. As soon as practicable after the date of adoption of the Second Amendment to the Plan, the Company shall direct the Trustee to transfer from the Fixed Income fund to the MCN Stock fund, on behalf of each former Participant who terminated employment on or after April 1, 1989 and prior to the date of adoption of the Second Amendment, and whose distribution has been deferred, an amount equal to the sum of (A) the amount required to purchase the number of shares of MCN Stock credited to his or her ESOP Account immediately prior to his or her termination of employment, plus (B) the amount of dividends that would have been credited thereon from April 1, 1989 to the date of such transfer. Such amount shall be credited to the ESOP Account of such former Participant. A former Participant whose distribution has been deferred pursuant to (1) above will not thereafter be eligible for withdrawals under section 9.3 or 9.5 or loans under section 9.10 but shall continue to have the voting and tender offer rights described sections 7.3 and 7.4 and to be treated as a Participant for purposes of Article VIII. A former Participant whose distribution has been deferred may initiate a distribution upon 30 days' prior written notice to the Company and shall receive an amount equal to the vested portion of his Plan Account as of the Valuation Date next following the expiration of such 30-day period, with such amount to be distributed in a lump sum cash payment except that-- (i) amounts invested in the MCN Stock fund shall be distributed in accordance with section 9.8, -64- 70 (ii) effective as of August 1, 1991, such former Participant may upon 30 days' prior notice to the Company receive a partial distribution rather than a total distribution, of the vested portion of his Account, but not more frequently than once in any calendar year (prior to December 1, 1993, not more frequently than once in any 12-month period), and (iii) to the extent that such distribution comes from the Fixed Income fund account, such distribution shall be subject to the provisions of section 9.9. Notwithstanding any other provision of this Plan, if a Participant attains age 70 1/2 and still has a balance allocated to his or her Plan Account, a distribution shall be made under section 9.1 as if the Participant had terminated employment in the month in which the Participant attains age 70 1/2. Such distribution shall in no event be later than April 1 of the calendar year following the year in which the Participant attains age 70 1/2. Distributions to such Participant shall be made annually thereafter no later than April 1 of each year and shall be equal to at least the minimum amount required to be distributed by Code section 401(a)(9). For purposes of this paragraph, the life expectancy of the Participant and the Participant's spouse shall be redetermined annually. (b) Suspension of Participation. If a Participant shall, prior to termination of his employment, cease to meet the eligibility requirements of the Plan, his allotments and Employer contributions on his behalf shall be suspended during the period of his ineligibility. Subject to section 3.1, distribution of such Participant's Plan Account shall be deferred until termination of his employment with the Company and any Affiliated Company. If the provisions of section 3.3 relating to the transfer of a Participant's Plan Account to the MichCon Savings and Stock Ownership Plan or its successor are not applicable-- -65- 71 (1) with respect to Participants who cease to meet the eligibility requirements of the Plan prior to January 1, 1987, the Company shall direct the Trustee to distribute the value of the Participant's Plan Account in accordance with section 9.1 whether or not such termination of employment shall be under the circumstances set forth in said section 9.1; and (2) with respect to Participants who cease to meet the eligibility requirements of the Plan subsequent to December 31, 1986, such distribution shall be in accordance with section 9.1 or 9.3, whichever is applicable. (c) Transfer of Employment. (1) A transfer of employment from an Employer to an Affiliated Company shall not be considered a termination of employment. (2) If a Participant shall be transferred to the employ of an Affiliated Company which has not elected to participate in the Plan, distribution of such Participant's Plan Account shall be deferred until the date on which he is no longer in the employ of the Company or any Affiliated Company, whereupon the Company shall direct the Trustee to distribute the value of the Participant's Plan Account in the manner prescribed in section 9.1, subject to the provisions of section 9.7, whether or not termination of employment shall be under circumstances set forth in said section 9.1. (d) Special Rules Relating to Distributions in the Event of Death. In the event that a Participant dies before a distribution of his Plan Account, the Company shall direct the Trustee to distribute the entire value of his Plan Account to his beneficiary no later than March 1 of the calendar year following the Participant's death, as provided in section 9.1. In -66- 72 the event of the death of the Participant after the distribution of his Plan Account has begun, any remaining balance in his Plan Account at the time of death will be distributed at least as rapidly as under the method of distribution in effect at the date of the Participant's death. 9.8 Distributions of Stock. In the case of distributions under section 9.1, 9.2, 9.3(b), 9.7(a), or 9.7(c)(2), the value of the Participant's MCN Stock and/or Primark Corporation Stock fund account(s), if any, shall be paid in full shares of stock except that cash shall be distributed in lieu of fractional shares; provided, however, that a Participant entitled to such a distribution may elect to receive cash in lieu of MCN Stock and/or Primark Corporation Stock. Except in the case of an election to receive cash in lieu of MCN Stock and/or Primark Corporation Stock-- (a) prior to August 1, 1991, the number of shares to be distributed from such account shall be the quotient of the value of such account as of the applicable Valuation Date divided by the value assigned by the Trustee to a share of MCN Stock or Primark Corporation stock for purposes of valuing the fund as of such Valuation Date; and (b) on and after August 1, 1991, the total number of shares allocated to such account shall be distributed from such account. Any remaining value of such account and, subject to the provisions of section 9.9, the value of the Participant's accounts in other funds shall be distributed in cash. Any transfer taxes payable with respect to the distribution of shares of stock shall be charged to the respective MCN Stock or Primark Corporation Stock fund. Distributions pursuant to section 9.3(a) and withdrawals under sections 9.5 and 9.6 shall be paid entirely in cash. -67- 73 9.9 Distributions from Fixed Income Fund. (a) Normal Form. Notwithstanding any provision of the Plan, other than the final paragraph of section 9.7(a), if a distribution is to be made under section 9.1(a) or (c) and the Participant has a Fixed Income fund account and at least one Hour of Employment prior to May 31, 1988, then unless the Participant or legal representative shall make an election in the manner prescribed in section 9.9(b), the value of such account (exclusive of the portion thereof attributable to diversification elections under section 13.5) shall be distributed by the purchase of a single premium annuity contract providing for monthly payments during the Participant's lifetime and, if the Participant is married on the date payment of his benefit commences and his spouse shall survive him, for monthly payments during the remainder of such spouse's lifetime, each such payment to such spouse being equal to one-half of the monthly payment received by the Participant, commencing no later than March 1 of the calendar year following the calendar year of the Participant's termination of employment, and delivery of such contract to the Participant within a reasonable time after the Participant's termination of employment. If a distribution is to be made under section 9.1(b) because of a Participant's death and the Participant had a Fixed Income fund account at the time of his death and at least one Hour of Employment prior to May 31, 1988, then unless the Participant had made or the Participant's spouse or beneficiary, as the case may be, makes an election at the time and in the manner prescribed in section 9.9(b), the value of the Participant's Fixed Income fund account (exclusive of the portion thereof attributable to diversification elections under section 13.5) shall be distributed by purchase of a single premium annuity contract providing -68- 74 for monthly payments to the Participant's spouse, or, if the Participant was not married on the day of his death, to his beneficiary during such person's lifetime, commencing no later than March 1 of the calendar year following the calendar year of the Participant's death and delivery of such contract to such person within a reasonable time after the date of Participant's death. (b) Election to Reject Normal Form. Subject to the provisions of this section 9.9(b), each Participant entitled to a distribution under section 9.9(a) (or legal representative on behalf of such a Participant) may, at any time during the 90-day period ending on the annuity starting date, elect to have the value of the Participant's Fixed Income fund account (exclusive of the portion thereof attributable to diversification elections under section 13.5) distributed by one or more of the methods set forth in section 9.9(c). Within 30 days after a Participant provides written notice to the Company of his intention to retire on his Early Retirement Date, Normal Retirement Date, or Disability Retirement Date, or within 30 days after the Company receives notice of a Participant's death, or within five business days after determining, pursuant to section 2.1(l), that a Participant is totally and permanently disabled, or within five business days after receiving notice of the legally established mental incompetency of the Participant, if the Participant has a Fixed Income fund account at such time, the Company shall deliver to such Participant or his legal representative, by mail or by personal delivery, written notice in nontechnical language explaining the terms and conditions of the annuity provided in section 9.9(a). -69- 75 The notice shall explain the Participant's or legal representative's right to elect an optional form of distribution and that such election may be revoked by the Participant or legal representative at any time prior to the annuity starting date or, if a lump sum payment is elected, prior to the first day on which all events have occurred which entitle the Participant or legal representative to the lump sum payment. The notice shall explain that a married Participant may elect a distribution pursuant to section 9.9(c) only if the spouse consents in writing to such election. Such written consent shall acknowledge consent to the designated beneficiary and the optional form of distribution, neither of which may be changed thereafter without again obtaining written spousal consent (or the consent of the spouse expressly permits changes by the Participant without further consent by the spouse). Such written consent shall acknowledge the effect of such election and shall be witnessed by a notary public or by a representative of the Company who is designated to act in such capacity by the Company. If the Participant establishes to the satisfaction of the Company that such written consent cannot be obtained because his spouse cannot be located, the requirement of such written consent shall be waived. Any election, change, or revocation under this section 9.9(b) shall be effective when written notice is delivered to the Company in a form approved by the Company for this purpose, provided such election, change, or revocation is delivered prior to the annuity starting date or, if a lump sum payment is elected, prior to the first day on which all events have occurred which entitle the Participant or legal representative to the lump sum payment. The notice -70- 76 shall explain that an effective revocation shall result in the benefit being provided as an annuity described in section 9.9(a). (c) Optional Forms. In addition to the form described in section 9.9(a), distribution of the value of a Participant's Fixed Income fund account (exclusive of the portion thereof attributable to diversification elections under section 13.5) may be made either-- (1) in a lump sum payment no later than March 1 of the calendar year following the calendar year of the Participant's termination of employment or death; or (2) by purchase of any form of single premium annuity contract that satisfies Code section 401(a)(9) as may from time to time be offered by the legal reserve life insurance companies with which the Trustee has agreements governing the investment of assets in the Fixed Income fund and delivery of such contract to the Participant or distributee within a reasonable time after the Participant's termination of employment or death. Within five business days after the Company receives an election pursuant to this provision, the Company shall provide the same written notice provided under section 9.9(b). An election pursuant to this provision shall be subject to the provisions of section 9.9(b). 9.10 Loans. The Trustee is hereby authorized to establish a loan program in accordance with this section 9.10. Upon application of a party in interest (as defined in ERISA section 3(14)) who is a Participant or beneficiary under the Plan, the -71- 77 Company shall direct the Trustee to make a cash loan to such Participant or beneficiary, secured by 50 percent of the nonforfeitable value of the Participant's Employee and Employer Salary Reduction and ESOP Accounts determined as of the date the loan is made. The loan program shall be administered by the Company subject to the following conditions and such other conditions that are consistent with Labor Regulation section 2550.408b-1 and are from time to time set forth in a written document, delivered to Participants and beneficiaries who are parties in interest (which document may but need not be the Summary Plan Description), which provisions shall constitute a part of the Plan and are hereby incorporated by reference: (a) Effective October 18, 1989, the term of a loan shall not extend beyond the earlier of four years or the date upon which the Participant or beneficiary ceases to be a party in interest; provided, however, that the four years shall be changed to eight years where the proceeds of the loan are used by the Participant or beneficiary to acquire the Participant's principal residence. (b) Effective October 18, 1989, a loan shall bear interest at a reasonable rate which shall be based upon the prevailing interest rate charged by persons in the business of lending money on similar commercial loans under comparable circumstances at the time that such loan is granted, as determined by the Company and uniformly applied. (c) Effective October 18, 1989, the amount of a loan (when added to the balance of other outstanding loans) shall not exceed the lesser of-- (1) $50,000 reduced by the excess (if any) of-- (A) the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the date on which such loan was made, over (B) the outstanding balance of loans outstanding on the date such loan was made, or -72- 78 (2) 50 percent of the nonforfeitable value of the Participant's Employee and Employer Salary Reduction and ESOP Accounts under the Plan which the Participant would have been entitled to receive if the Participant's employment had terminated on the date such loan was made. In no case shall a Participant be entitled to a loan under this Plan if the amount of the proposed loan is less than $500. (d) A loan shall be evidenced by a promissory note. (e) Payments of principal and interest shall be made by approximately equal payments not less frequently than monthly on a basis that would permit the loan to be fully amortized over its term. Effective October 18, 1989, loan payments shall be made by payroll deductions for Participants in active pay status. (f) Appropriate disclosure shall be made pursuant to the Truth in Lending Act to the extent applicable. (g) Amounts of principal and interest received on a loan shall be credited to the Participant's account and the outstanding loan balance shall be considered an investment of the assets of the account. Payment of principal and interest shall be credited to the investment funds in the same proportion as the amount distributed from the funds from which the loan was granted to the Participant, except amounts that would otherwise be credited to the Primark Corporation Stock fund shall be credited to the MCN Stock fund. (h) The frequency of loans and the minimum amount for a loan shall be determined through uniform rules prescribed by the Company and at the sole discretion of the Company. (i) All applications for a loan shall be submitted to the Company on a form prescribed by the Company. Distribution shall be made as soon as reasonably practicable after the application of the loan is received. -73- 79 (j) If a Participant borrows from an account which is invested in more than one fund, he shall instruct the Company as to the funds from which the loan is to be applied; provided, however, that no borrowing shall be applied from the MCN Stock fund unless and until the Participant's ability to borrow from each of the other funds has been exhausted. (k) A married Participant may not borrow any amount from the Plan unless his spouse executes a written consent as hereinafter provided. Such consent must be executed during the 90-day period ending on the date on which the loan is made and shall specifically provide that the spouse consents both to the loan and to the use of the Participant's Salary Reduction and ESOP Accounts as security for the loan. The consent shall acknowledge the effect of the use of the Participant's accounts as security for the loan and shall be witnessed by a notary public or a representative of the Company who is designated to act in such capacity by the Company. (l) In the event a Participant defaults on a loan, the entire outstanding balance of and accrued interest on the loan shall be due and payable. The Trustee and/or Company may pursue collection on such defaulted loan by any means generally available to a creditor where a promissory note is in default, or if the entire amount due is not paid by such Participant following the default, the amount of such loan default shall be charged against the "secured portion" of the Participant's Plan Account and treated as a distribution with respect to such Participant; provided, however, that such a charge against a Participant's Plan Account shall not occur with respect to funds in his Employee Salary Reduction Account at a time so as to cause a violation of Code section 401(k)(2)(B)(i). -74- 80 9.11 Definition of Allotments and Employer Contributions. For the purposes of this Article IX, a Participant's allotments shall include only those allotments made either as a Voluntary Deduction or a Salary Reduction which have not been previously withdrawn or distributed. If a Participant has previously had a portion of his Plan Account forfeited under section 9.2, the Employer contributions, exclusive of those made as a Salary Reduction to the Plan on his behalf, shall include only such Employer contributions made subsequent to such forfeiture. 9.12 Spousal Consent to Payment. Subject to section 9.7(a), the spouse of a married Participant or former Participant shall be required to consent in writing to any in-service withdrawal, loan, or distribution under the Plan to the Participant or former Participant; provided, however, for distributions on account of termination of employment, this sentence shall be effective as of January 1, 1993. The spouse's consent shall be in such form as the Company may prescribe. 9.13 Distributions Pursuant to a Qualified Domestic Relations Order. Upon receipt of a domestic relations order, the Company will notify the involved Participant and any alternate payee that the order has been received and explain the Plan's procedures for determining whether the order is a qualified domestic relations order as defined in Code section 414(p). After determining that the order is a qualified domestic relations order, the Company shall direct the Trustee to distribute or segregate the Participant's Account as provided in the qualified domestic relations order. If required by the qualified domestic relations order, the Trustee shall make distribution prior to the time that the Participant, whose account is subject to distribution, could have received a distribution. -75- 81 In a case of a dispute regarding the validity of a domestic relations order or the amounts or identities of parties to be paid thereunder, the Company may segregate the portion of the Participant's account in question, and may bring an action in a court of competent jurisdiction to determine the proper amount and/or recipient of benefits, or may submit such segregated amount to a court of competent jurisdiction (through an interpleader action or otherwise) until resolution of the matter. Further, if the Company receives notice that a domestic relations order is forthcoming, the Company may suspend payments from the Participant's Account or may follow the procedures described in the preceding sentence, until resolution of the matter. 9.14 Direct Rollovers of Eligible Distributions. (a) General. This section applies to distributions made on or after January 1, 1993. Notwithstanding any provision of the Plan to the contrary that would otherwise limit a distributee's election under this section, a distributee may elect, at the time and in the manner prescribed by the Company, to have any portion of an eligible rollover distribution paid directly to an eligible retirement plan specified by the distributee in a direct rollover. (b) Definitions. (1) Eligible rollover distribution. An eligible rollover distribution is any distribution of all or any portion of the balance to the credit of the distributee, except that an eligible rollover distribution does not include: any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the distributee or the joint lives (or joint life expectancies) of the distributee and the distributee's designated beneficiary, or for a -76- 82 specified period of ten years or more; any distribution to the extent such distribution is required under Code section 401(a)(9); and the portion of any distribution that is not includible in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to employer securities). (2) Eligible retirement plan. An eligible retirement plan is an individual retirement account described in Code section 408(a), an individual retirement annuity described in Code section 408(b), an annuity plan described in Code section 403(a), or a qualified trust described in Code section 401(a), that accepts the distributee's eligible rollover distribution. However, in the case of an eligible rollover distribution to the surviving spouse, an eligible retirement plan is an individual retirement account or individual retirement annuity. (3) Distributee. A distributee includes an Employee or former Employee. In addition, the Employee's or former Employee's surviving spouse and the Employee's or former Employee's spouse or former spouse who is the alternate payee under a qualified domestic relations order, as defined in Code section 414(p), are distributees with regard to the interest of the spouse or former spouse. (4) Direct rollover. A direct rollover is a payment by the Plan to the eligible retirement plan specified by the distributee. (c) Waiver of 30-Day Notice Period. If a distribution is one to which Code sections 401(a)(ll) and 417 do not apply, such distribution may commence less than 30 days after the notice required under section 1.411(a)-11(c) of the Income Tax Regulations is given, provided that: (1) the Company clearly informs the Participant that the Participant has a right to a period of at -77- 83 least 30 days after receiving the notice to consider the decision of whether or not to elect a distribution (and, if applicable, a particular distribution option), and (2) the Participant, after receiving the notice, affirmatively elects a distribution. -78- 84 Article X. Administration 10.1 Plan Administration and Interpretation. (a) The Company shall be responsible for the administration of the Plan. The Company shall have all such powers as may be necessary to carry out the provisions of the Plan and may from time to time establish rules and procedures for the administration of the Plan and the transaction of the Plan's business. (b) The Company shall have the exclusive right to make any finding of fact necessary or appropriate for any purpose under the Plan. The Company shall have the maximum discretion permitted by law to interpret and construe the terms of the Plan and to resolve all issues arising under the Plan including, but not limited to the authority to-- (1) construe disputed or doubtful terms of the Plan; (2) determine the eligibility of an individual to participate in the Plan; (3) determine the amount, if any, of benefits to which any Participant, former Participant, beneficiary, or other person may be entitled under the Plan; (4) determine the timing and manner of payment of benefits; and (5) resolve all other issues arising under the Plan. To the extent permitted by law, all findings of fact, determinations, interpretations, and decisions of the Company shall be conclusive and binding upon all persons having or claiming to have any interest or right under the Plan. The Employers shall, from time to time, on request of the Company, furnish to the Company such data and information as the Company shall require in the performance of its duties. (c) The Company shall each month collect Employee allotments and Employer contributions from each -79- 85 Employer and shall deliver the amounts collected to the Trustee, together with instructions concerning the portions of such total amount to be invested in each fund. (d) The Company shall direct the Trustee to make payments of amounts to be distributed or withdrawn from the Trust under Article IX and to make any transfers from one fund to another directed by Participants under section 6.3. 10.2 Notice to Employees. All notices, reports, and statements given, made, delivered, or transmitted to a Participant shall be deemed to have been duly given, made, or transmitted when mailed with postage prepaid and addressed to the Participant at the address last appearing on the books of the Employer. A Participant may record any change of his address from time to time by written notice filed with the Employer. 10.3 Notices to Employers. Written directions, notices, and other communications from Participants to the Employers shall be mailed by first class mail with postage prepaid or delivered to such location as shall be specified upon the forms prescribed by the Company for the giving of such directions, notices, and other communications, and shall be deemed to have been received by the addressee when received at such location. Any other notice to the Employers shall be addressed-- (a) If intended for the Company: MichCon Investment and Stock Ownership Plan c/o Michigan Consolidated Gas Company 500 Griswold Street Detroit, Michigan 48226 (b) If intended for any other Employer, at its principal place of business. 10.4 Participants' Acceptance of the Provisions of the Plan. Each Participant at the time of becoming a Participant in the -80- 86 Plan and as a condition of participation shall sign an instrument evidencing the fact that he accepts and agrees to all provisions of the Plan. 10.5 Audit of Plan Records. The records of the Company and the records of the Employers in respect of the Plan shall be examined annually by a firm of independent public accountants appointed by the Company. Such accountants shall, on the basis of such examination, make such reports to the Company and to the Employers as they may request. The audited records of the Company and the Employers shall be conclusive in respect of all matters involved in the administration of the Plan. 10.6 Claims Procedure. If any Participant or distributee believes he is entitled to benefits in an amount greater than those which he is receiving or has received, he may file a claim with the Secretary of the Company. Such a claim shall be in writing and state the nature of the claim, the facts supporting the claim, the amount claimed, and the address of the claimant. The Secretary of the Company shall review the claim and, within a reasonable period of time after receipt of the claim, give written notice by registered or certified mail to the claimant of his decision with respect to the claim. Such notice shall be written in a manner calculated to be understood by the claimant and, if the claim is wholly or partially denied, set forth the specific reasons for the denial, specific references to the pertinent Plan provisions on which the denial is based, a description of any additional material or information necessary for the claimant to perfect the claim, and an explanation of why such material or information is necessary, and an explanation of the claim review procedure under the Plan. The Secretary shall also advise the claimant that he or his duly authorized representative may request a review by the Company of the denial by filing with the Company, within 65 days after notice of the denial has been received by the claimant, a -81- 87 written request for such review. The claimant shall be informed that he may have reasonable access to pertinent documents and submit comments in writing to the Company within the same 65-day period. If a request is so filed, review of the denial shall be made by the Company and the claimant shall be given written notice of the Company's final decision. Such notice shall be provided within 60 days after receipt of such request. Such notice shall include specific reasons for the decision and specific references to the pertinent Plan provisions on which the decision is based and shall be written in a manner calculated to be understood by the claimant. 10.7 Effect of a Mistake. In the event of a mistake or misstatement as to the eligibility, participation, or service of any Participant, or the amount of payments made or to be made to a Participant or beneficiary, the Company shall, if possible, adjust the Plan's records and cause to be withheld or accelerated or otherwise make adjustment of such amounts of payments as will in its sole judgment result in the Participant or beneficiary receiving the proper amount of payments under the Plan. -82- 88 Article XI. Amendment and Termination 11.1 Amendment. The Company may at any time and from time to time amend or modify the Plan by written instrument duly adopted by the Board of Directors of the Company. Any such amendment or modification shall become effective on such date as the Company shall determine, may apply to Participants in the Plan at the time thereof as well as future Participants, but may not reduce the Plan Account of any Participant as of the date of adoption of such amendment or modification. 11.2 Withdrawal. If an Employer shall withdraw from the Plan under section 12.2, or if an Employer shall adopt an amendment to the Plan which shall render impracticable the continued administration of the Plan as a joint plan of the several Employers, the Company shall determine the portions of the various funds held by the Trustee which are applicable to the Participants of such Employer and shall direct the Trustee to segregate such portions in a separate trust. Such separate trust shall thereafter be held and administered as a part of the separate plan of such Employer. After such portions of the funds have been segregated in a separate trust, no such Participant or any distributee with respect to such Participant shall have any right to any benefit under the Plan or any claim against the Trust. 11.3 Termination. Any Employer may at any time terminate its participation in the Plan by resolution of its Board of Directors without obtaining the consent of or giving notice to any Participant or collective bargaining representative. In the event of any such termination, the Company shall determine the portions of the various funds held by the Trustee which are applicable to the Participants of such Employer and shall direct the Trustee to distribute such portions to such Participants ratably in proportion to the values of their respective fund accounts; provided, however, amounts attributable to a Participant's Elective Deferrals shall not be distributed on -83- 89 account of such termination if the Employer, after such termination, maintains a defined contribution plan (other than an employee stock ownership plan or a simplified employee pension). The portions of the MCN Stock fund and the Primark Corporation Stock fund so distributed shall be distributed in kind except that cash shall be distributed in lieu of fractional shares. The portions of the Fixed Income fund and other investment funds so distributed shall be distributed in cash or in kind, or partly in cash and partly in kind, as determined by the Company. Upon termination or partial termination of the Plan by any Employer or upon the complete discontinuance of contributions by any Employer, the benefits under the Plan of all affected Participants employed or formerly employed by such Employer shall become nonforfeitable. 11.4 Allocation of Funds Between Employers. The portion of a fund applicable to Participants of a particular Employer shall be an amount which bears the same ratio to the value of the fund which the aggregate value of the fund accounts of Participants employed by such Employer bears to the total value of the fund accounts of all Participants. 11.5 Trust to be Applied Exclusively for Participants and Their Beneficiaries. Subject to section 13.3, any provision of the Plan to the contrary notwithstanding, it shall be impossible for any part of the Trust to be used for or diverted to any purpose not for the exclusive benefit of Participants and their beneficiaries either by operation or termination of the Plan, by power of amendment, or by other means. Notwithstanding the preceding paragraph, if a contribution is made to the Trust by an Employer by a mistake of fact, then such contribution shall be returned to such Employer within one year after the payment of the contribution; and if any part or all of a contribution is disallowed as a deduction under Code section 404, then to the extent such contribution is disallowed as a -84- 90 deduction it shall be returned to such Employer within one year after the disallowance. All Employer contributions are conditioned upon their deductibility under Code section 404. -85- 91 Article XII. Participation by Affiliated Companies 12.1 Adoption of the Plan. Any Affiliated Company may become a participating Employer under the Plan by (a) taking such corporate action as shall be necessary to adopt the Plan, and (b) executing and delivering such instruments and taking such other action as may be necessary or desirable to put the Plan into effect with respect to such Affiliated Company. The Plan shall become effective with respect to each particular Affiliated Company which becomes a participating Employer after January 1, 1993, as of a date to be determined by the Board of Directors of such Employer after complying with all legal requirements pertaining to the participation of such Employer in the Plan. 12.2 Withdrawal from the Plan. Any Employer may withdraw from participation in the Plan at any time by filing with the Company a duly certified copy of a resolution of its Board of Directors to that effect and giving notice of its intended withdrawal to the Company, the other Employers, and the Trustee at least 30 days prior to the effective date of withdrawal. 12.3 Company as Agent for Employers. Each Employer named under section 2.1(u), other than the Company, hereby appoints, and each other corporation which shall become an Employer pursuant to section 12.1 or 13.7 by so doing shall be deemed to have appointed the Company its agent to exercise on its behalf all of the powers and authorities hereby conferred upon the Employers by the terms of the Plan, including, but not by way of limitation, the power to amend, restate, and terminate the Plan. The authority of the Company to act as agent shall continue unless and until the portion of the Trust fund held for the benefit of Employees of the particular Employer and their beneficiaries is set aside in a separate trust as provided in section 11.2. -86- 92 Article XIII. Special Provisions Relating to the ESOP 13.1 Establishment of ESOP. The MichCon Employee Stock Ownership Plan for Union Employees was originally established effective as of April 1, 1989. Each Employer shall make contributions to the ESOP in accordance with section 4.3 hereof and the assets of the ESOP shall be invested at all times primarily in MCN Stock. The Company from time to time may direct the Trustee to incur debt in accordance with section 13.4 hereof to finance the acquisition of MCN Stock. 13.2 ESOP Account. The Company shall establish an ESOP Account in the name of each Participant to which there shall be credited or charged-- (a) the Employer contributions under section 4.3(a) and (c) hereof made on behalf of such Participant; (b) the shares allocated to the Participant pursuant to section 13.4(d) hereof; and (c) the investment gains and losses on such amounts. A Participant's ESOP Account shall be invested only in the MCN Stock fund, except to the extent that monies diversified under section 13.5 may, at the Participant's election, be directed to the Equities fund, the Senior Securities fund, or the Fixed Income fund. 13.3 Discrimination Testing. For purposes of the limitations on Salary Reduction allotments set forth in section 4.8 and the limitations on Voluntary Deduction allotments and Employer contributions set forth in section 4.11, the ESOP and non-ESOP portions of the Plan shall be tested separately. For purposes of such testing-- (a) the ESOP portion of the Plan shall mean Employer contributions under section 4.3(a) made on behalf of the Participant and the shares allocated to a Participant's ESOP Account pursuant to section 13.4(d); and -87- 93 (b) the non-ESOP portion of the Plan shall mean all Elective Deferrals, Voluntary Deductions and Employer contributions under section 4.2. 13.4 Loans. (a) Stock Acquired with Exempt Loan. The Company may direct the Trustee to incur a loan on behalf of the ESOP in a manner and under conditions which will cause the loan to qualify as an "exempt loan" within the meaning of Code section 4975(d)(3). A loan shall be used primarily for the benefit of Participants and their beneficiaries. The proceeds of each such loan shall be used, within a reasonable time after the loan is obtained, only to purchase MCN Stock, to repay the loan, or to repay any prior loan. Any such loan shall provide for a reasonable rate of interest and an ascertainable period of maturity, and shall be without recourse against the Plan. Any such loan shall be secured solely by shares of MCN Stock acquired with the proceeds of the loan and shares of MCN Stock that were used as collateral on a prior loan which was repaid with the proceeds of the current loan. MCN Stock acquired with the proceeds of a loan, including shares pledged as collateral, shall be placed in a Suspense Account and released in accordance with subsection (b) below as the loan is repaid as if all shares in the Suspense Account were pledged. MCN Stock released from the Suspense Account shall be allocated in the manner described in subsection (d) below. No person entitled to payment under a loan made pursuant to this section 13.4 shall have recourse against any assets of the Plan other than the MCN Stock used as collateral for the loan, Employer contributions -88- 94 under section 4.3 that are available to meet obligations under the loan, and earnings attributable to such collateral and the investment of such contributions. Employer contributions under section 4.3(b) made with respect to any Plan Year during which the loan remains unpaid, and earnings on such contributions, shall be deemed available to meet obligations under the loan, unless otherwise provided by the Employer at the time such contributions are made. (b) Release of Pledged Shares. Any pledge of MCN Stock as collateral under this section 13.4 shall provide for the release of shares so pledged upon the payment of any portion of the principal of the loan. Shares so pledged shall be released in the proportion that the principal paid on the loan bears to the total principal amount of the loan, as provided in Treasury Regulation 54.4975-7(b)(8)(ii). The number of shares of MCN Stock that shall be released with each principal payment on the loan shall be equal to the number of shares of MCN Stock held as collateral on the loan immediately prior to the release multiplied by a fraction the numerator of which is the amount of principal of the loan repaid on such date and the denominator of which is the sum of the numerator plus the remaining outstanding principal amount of the loan after giving effect to the repayment of principal of the loan on such date. Each loan under this section 13.4 shall comply with the requirements of Treasury Regulation 54.4975-7(b)(8)(ii). If such a loan provides for monthly principal payments, shares of MCN Stock shall be released monthly. (c) Repayment of Loan. Payments of principal and interest on any loan under this section 13.4 shall be made by the Trustee at the direction of the Company solely from-- -89- 95 (1) the proceeds of such loan, if any portion of such proceeds are used for such purpose within a reasonable period of time after the loan is obtained as provided in section 13.4(a) above; (2) Employer contributions under section 4.3(b) available to meet obligations under the loan; (3) earnings from the investment of such contributions; (4) earnings attributable to MCN Stock acquired with the proceeds of such loan, whether allocated or unallocated; (5) the earnings on other allocated shares of MCN Stock held by the ESOP if the Internal Revenue Service, by private letter ruling, advises the Company that the use of such earnings to repay the loan will be deductible under Code section 404(k)(2)(C) and will not violate the requirements of Code section 4975; and (6) the proceeds of a subsequent loan made to repay the loan. The contributions and earnings available to pay a loan must be accounted for separately by the Company until all loans under this section 13.4 have been paid. If dividends on MCN Stock allocated to the ESOP Account of any Participant are used to repay any loan, shares of MCN Stock with a fair market value not less than the amount of such dividends shall be allocated in accordance with section 4.3(c) to the ESOP Account of such Participant prior to the end of the Plan Year during which (but for the use of the dividends to repay the loan) such dividend would have been allocated to the ESOP Account of such Participant. (d) Allocation of Released Shares. Subject to the limitations in section 4.11 on Annual Additions to a Participant's accounts, shares of MCN Stock released from a Suspense Account described in section 13.4(a) shall be allocated immediately to the ESOP Accounts of -90- 96 each Participant in the proportion that the contribution that would be required to be made on behalf of such Participant under section 4.3(a)(1) for the applicable period if no shares were allocated under section 4.3(a)(2) during such period bears to the total of all Employer contributions that would be required under section 4.3(a)(1) hereof for the applicable period if no shares were allocated under section 4.3(a)(2) during such period. 13.5 Diversification. Any Participant or any former Participant whose distribution has been deferred pursuant to section 9.7(a), who, in either case, has completed at least ten years of participation in the Plan, and who has attained the age of 55 is a "Qualified Participant". Any Qualified Participant shall have the right to make an election to direct the investment of a portion of his ESOP Account. Such a Participant may elect within 90 days after the close of each Plan Year in the six plan-year period beginning with the first Plan Year in which the individual becomes a Qualified Participant to diversify 25 percent of his ESOP Account, less any amount to which a prior election applies. In the case of the last year to which an election applies, 50 percent shall be substituted for 25 percent. The portion of a Qualified Participant's ESOP Account which is eligible for diversification may be invested in the Fixed Income fund and/or any other investment funds under the Plan, in any combination thereof. 13.6 Put Option. If MCN Stock becomes not readily tradable on an established market, then any Participant who is otherwise entitled to a distribution of his ESOP Account, shall have the right (hereinafter referred to as "Put Option") to require that his Employer repurchase any MCN Stock allocated to his ESOP Account under a fair valuation formula. The Put Option shall be exercisable only by written notice to the Participant's Employer during the 60-day period immediately following the date of -91- 97 distribution and if the Put Option is not exercised within such 60-day period, then it can be exercised for an additional period of 60 days in the following Plan Year. The period during which the Put Option is exercisable shall not include any time when a Participant is unable to exercise it because his Employer is prohibited from honoring it by applicable federal or state law. This Put Option shall be nonterminable within the meaning of Treasury Regulation 54.4975-(11)(a)(ii). The amount paid for MCN Stock under the Put Option shall be paid in substantially equal periodic payments (not less frequently than annually) over a period beginning not later than 30 days after the exercise of the Put Option and not exceeding five years. There shall be adequate security provided and reasonable interest paid on the unpaid balance due under this section 13.6. 13.7 Purchase of MCN Stock. The ESOP may acquire shares of MCN Stock on a national securities exchange, from the Company or any Affiliated Company or otherwise; provided, however, that if any shares of MCN Stock are purchased from the Company or any Affiliated Company, the price shall not exceed an amount which constitutes adequate consideration (as defined in ERISA section 3(18) and any Regulations thereunder) and such purchase shall satisfy all other requirements of ERISA and the Code applicable to such purchases. Except as provided in section 13.6 or as otherwise required by applicable law, no shares of MCN Stock acquired by the ESOP shall be subject to a put, call, or other option, or buy-sell or similar arrangement while held by and when distributed from the Plan, whether or not any part of the Plan is then an ESOP. The protection afforded to Participants in the preceding sentence is nonterminable within the meaning of Treasury Regulation section 54.4975-(1)(a)(ii). -92- 98 Article XIV. Miscellaneous 14.1 Beneficiary Designation. Subject to the provisions of section 9.9 and this section 14.1, each Participant shall have the right to designate a beneficiary or beneficiaries to receive any distribution to be made under section 9.1 upon the death of such Participant, or, in the case of a Participant who dies subsequent to termination of his employment but prior to the distribution of the entire amount to which he is entitled under the Plan, any undistributed balance to which such Participant would have been entitled. In the event of the death of a Participant whose spouse survives him, the beneficiary of the Participant shall be his surviving spouse unless such spouse has consented in writing to the designation of another beneficiary or beneficiaries. Any such written consent shall acknowledge the effect of such election and shall be witnessed by a notary public or by a representative of the Company who is designated to act in such capacity by the Company. In the event a Participant dies without a surviving spouse, or, in the event the surviving spouse of a Participant has executed the written consent hereinabove described, any distributions to be made under section 9.1 upon the death of the Participant shall be made to his designated beneficiary or beneficiaries. If the Participant establishes to the satisfaction of the Company or its designated representative that such written consent cannot be obtained because his spouse cannot be located, the requirement of such written consent shall be waived. If no beneficiary has been named by a Participant who dies without a surviving spouse or if the beneficiary designated by such a Participant or by a Participant whose surviving spouse has executed the written consent hereinabove described has predeceased the Participant or such designated beneficiary has -93- 99 died prior to complete disbursement of the Participant's Plan Account, the value of his account, or the undistributed portion thereof, shall be paid by the Trustee at the direction of the Company-- (a) to the surviving spouse of such deceased Participant, if any; (b) if there shall be no surviving spouse, to the surviving children of such deceased Participant, if any, in equal shares; (c) if there shall be no surviving spouse or surviving children, to the executors or administrators of the estate of such deceased Participant; or (d) if no executor or administrator shall have been appointed for the estate of such deceased Participant, to the person or persons who would be entitled to the personal estate of such deceased Participant under the laws of his state of domicile if he had died leaving no will. In the event that a Participant and his spouse die under circumstances such that it is not clear whether the spouse survived the Participant, the Participant shall be presumed to have survived the spouse. 14.2 Incompetency. Any distribution under this Plan which is payable to a beneficiary who is a minor or to a Participant or beneficiary who, in the opinion of the Company, is unable to manage his affairs by reason of illness or mental incompetency, may be made to or for the benefit of any such Participant or beneficiary in such of the following ways as the Company shall direct: (a) Directly to any such minor beneficiary, if, in the opinion of the Company, he is able to manage his affairs; (b) To the legal representative of any such Participant or beneficiary; or (c) To some near relative of any such Participant or beneficiary to be used for the latter's benefit. -94- 100 14.3 Expenses. Except as otherwise provided in the Plan, all costs and expenses incurred in administering the Plan, including the expenses of the Company, the fees and expenses of the Trustee, the fees of its counsel, and other administrative expenses, shall be borne by the Employers in such proportions as the Company shall determine to be equitable and proper having regard to the nature of the particular expense. 14.4 Nonassignability. Except as may be required to comply with a qualified domestic relations order (as defined in Code section 414(p)), it is a condition of the Plan, and all rights of each Participant shall be subject thereto, that no right or interest of any Participant in the Plan or in a Plan Account shall be assignable or transferable in whole or in part, either directly or by operation of law or otherwise, including, but not by way of limitation, execution, levy, garnishment, attachment, pledge, or bankruptcy but excluding devolution by death or mental incompetency, and no right or interest of any Participant in the Plan or in his Plan Account shall be liable for, or subject to, any obligation or liability of such Participant. 14.5 Employment Noncontractual. The Plan confers no right upon any Employee to continue in employment. 14.6 Merger or Consolidation with Another Plan. A merger or consolidation with, or transfer of assets or liabilities to, any other plan shall not be effected unless the terms of such merger, consolidation, or transfer are such that each Participant, distributee, beneficiary, or other person entitled to receive benefits from the Plan would, if the Plan then terminated, receive a benefit immediately after the merger, consolidation, or transfer which is equal to or greater than the benefit such person would have been entitled to receive immediately before the merger, consolidation, or transfer if the Plan had then terminated. -95- 101 If any other plan shall be merged into and become a part of this Plan, each Participant or the person entitled to receive a benefit under such other plan shall be entitled to receive a benefit under this Plan which is equal to the benefit such person would have been entitled to receive had such other plan terminated immediately before the merger. 14.7 Continuance by a Successor. In the event that any Employer corporation shall be reorganized by way of merger, consolidation, transfer of assets, or otherwise, so that another Affiliated Company shall succeed to all or a portion of such Employer's business, such successor corporation, with the consent of each other participating Employer, may be substituted for such Employer under the Plan by adopting the Plan and becoming a party to the Trust Agreement. Employee allotments and Employer contributions shall be automatically suspended from the effective date of any such reorganization until the date upon which the substitution of such successor corporation for the Employer under the Plan becomes effective. If, within 90 days from the effective date of any such reorganization, such successor corporation shall not have become a party to the Plan, or, if the Employer shall adopt a plan of complete liquidation other than in connection with a reorganization, the Plan shall be automatically terminated with respect to Employees of such Employer as of the close of business on the ninetieth day following the effective date of such reorganization or as of the close of business on the date of adoption of such plan of complete liquidation, as the case may be, and the Trustee shall distribute the portion of the Trust applicable to Participants of such Employer in the manner provided in section 11.3. -96- 102 14.8 Elimination of Certain Provisions. Effective-- (a) as of May 1, 1991, all references to Primark Corporation Stock and the Primark Corporation Stock fund shall be deleted from the Plan; and (b) as of January 1, 1993, all provisions that ceased to apply on any date prior to January 1, 1993 shall be deleted from the Plan. * * * * * * * * * * -97- 103 IN WITNESS WHEREOF, Michigan Consolidated Gas Company has caused its corporate name to be hereunto affixed by its duly authorized officers as of the 29th day of December, 1993.

MCNISH ------------------------------------ Its SECRETARY AND GENERAL COUNSEL --------------------------------- 7 116 THIRD AMENDMENT TO THE 1989 AMENDMENT AND RESTATEMENT OF THE MICHCON INVESTMENT AND STOCK OWNERSHIP PLAN WHEREAS, Michigan Consolidated Gas Company (the "Company") has previously established the MichCon Investment and Stock Ownership Plan (the "Plan"), which was most recently restated effective January 1, 1989; WHEREAS, FURTHER, pursuant to Section 11.1 of the Plan, the Company has reserved the right to amend the Plan from time to time; NOW, THEREFORE, the Plan is hereby amended as follows, effective January 1, 1996 except as otherwise provided below: 1. Section 2.1(ww) shall be amended in its entirety as follows: "Valuation Date" means each business day on which the New York Stock Exchange shall be open for business. 2. Section 4.5(a) shall be clarified by adding the following at the end thereof, effective January 1, 1995: Former Employees who are Participants and who receive an eligible rollover distribution from another plan sponsored by an Employer may make rollover contributions in accordance with this section. 3. Section 9.10(g) shall be amended in its entirety as follows: (g) Amounts of principal and interest received on a loan shall be credited to the Participant's account and the outstanding loan balance shall be considered an investment of the assets of the account. Payment of principal and interest related to loans made from a Participant's ESOP Account shall be credited to such Participant's ESOP Account. Payment of principal and interest related to loans made from a Participant's Investment Plan Account shall be credited to the Participant's Investment Plan Account and shall be invested in the investment funds in the same proportions as the investment election then in effect by the Participant under Article VI. 1 117 4. A new Section 14.9 shall be added to the Plan, effective October 12, 1996, which shall read as follows: 14.9 USERRA Rights. Notwithstanding any provision of the Plan to the contrary, contributions, benefits and service credit with respect to qualified military service will be provided in accordance with Code Section 414(u), to the extent applicable. Loan repayments will be suspended under this Plan as permitted under Code Section 414(u). 5. A new Article XV shall be added to the Plan, effective as of January 1, 1996 provided that a favorable private letter ruling in connection with this addition is received from the Internal Revenue Service on or before January 31, 1997, and which is otherwise effective on the January 1 of the year in which such favorable private letter ruling is received, which such Article XV shall read as follows: Article XV. Redesignation of ESOP This Article XV designates that part of the non-ESOP portion of the Plan which is invested in the MCN Stock Fund becomes part of the ESOP portion of the Plan. This Article XV also sets forth certain provisions regarding the operation of the ESOP portion of the Plan, such provisions to supersede any contrary provisions of the Plan. Except as specifically provided in this Article XV, the provisions of this Article XV, including the redesignation of the ESOP portion of the Plan described herein, shall not affect any beneficiary designations or any other applicable agreements, elections, or consents that Participants, spouses, or beneficiaries validly executed under the terms of the Plan before the execution date of the Plan amendment which first adopts this Article XV, and such designations, agreements, elections and consents shall continue to apply in the same manner as they did prior to such amendment. The ESOP, as set forth in this Article XV, is intended to meet with requirements of an employee stock ownership plan, as defined in Section 4975(e)(7) of the Code and the accompanying regulations, and Section 407(d)(6) of ERISA. As provided below, the ESOP is designed to invest primarily in qualifying employer securities of MCN Corporation. 15.1 REDESIGNATION OF ESOP PORTION OF PLAN. Effective as of January 1, 1996, the ESOP portion of the Plan shall consist of the ESOP Account of each Participant plus the remaining part of each Participant's Plan Account that is invested in the MCN Stock Fund. The put option provisions of Section 13.6 shall apply to the entire ESOP portion of the Plan. However, only a Participant's ESOP Account shall be subject to the restrictions described in the first sentence of Section 6.3. 2 118 15.2 ALLOCATION OF INVESTMENT PLAN ACCOUNT BALANCES TO ESOP PORTION OF PLAN. On and after January 1, 1996, all amounts contributed, transferred or designated as allocable to the Investment Plan Account of any Participant shall be treated as part of the ESOP portion of the Plan to the extent the Participant has directed the investment of such amounts in the MCN Stock Fund in accordance with Article VI of the Plan. 15.3 DISTRIBUTION OF DIVIDENDS ON MCN STOCK. At the direction of the Company exercised in its sole discretion, the Trustee will, after dividends are paid on MCN Stock held in the Trust, but in no event later than 90 days following the end of the Plan Year in which such dividends are paid (to the extent such dividends are not used to make payment on an exempt loan as provided for in section 13.4(c) of the Plan), either (i) distribute to Participants such portion of the dividends attributable to the interests in MCN Stock held in their Plan Accounts (or, if so determined by the Company, their ESOP Accounts) as described below or, (ii) arrange to have such dividends distributed directly to Participants by the Employer, or (iii) arrange to have such dividends distributed to Participants by a dividend disbursement agent selected by the Company, which may be the Employer's payroll department. In its sole discretion, the Company may direct the Trustee to have such dividends distributed only to Participants who elect to receive such dividend distributions in accordance with procedures established by the Company (which such procedures may apply to all Participants, solely to Participants described in (a) below, or solely to Participants not described in (a) below). Further, in its sole discretion, the Company may establish procedures that would permit Participants to elect to have dividends distributed to them in a single sum rather than over periods that might otherwise be determined by the Company to correspond with Employer payroll practices. The distribution of dividends on MCN Stock held in a Participant's Plan Account (or, if so determined by the Company, a Participant's ESOP Account ) shall be in the following amounts: a. Participants who have terminated employment with the Employers and all other nonemployees with Plan Account balances (such as QDRO alternate payees and beneficiaries of deceased Participants) shall receive distributions of all of the dividends paid on the MCN Stock held in their Plan Accounts (or, if so determined by the Company, their ESOP Accounts), provided, however, that the aggregate amount of such distributions to each such Participant or other individual shall not exceed $3,500 in any Plan Year (unless the Company, in its sole discretion, uniformly permits such Participants to elect to receive such distributions without limitation). 3 119 b. Participants who are employees who participate in the MCN Supplemental Savings Plan shall receive distributions of all of the dividends paid on the MCN Stock held in their Plan Accounts (or, if so determined by the Company, their ESOP Accounts). c. Each other Participant not described in (a) or (b) above shall receive distributions equal to the amount of Additional Allotments that he or she would be permitted to make under Section 15.4 below, subject to the limitations of Section 15.5 below, unless such Participant affirmatively elects to receive a distribution of 100% of the dividends paid on the MCN Stock held in his or her Plan Account (or, if so determined by the Company, his or her ESOP Account). For purposes of this Section 15.3, the ESOP portions of both the MichCon Savings and Stock Ownership Plan and the MichCon Investment and Stock Ownership Plan shall be considered in the aggregate for each Participant and the payment of dividend amounts on MCN Stock held in the Plan Accounts (or, if so determined by the Company, the ESOP Accounts) under both plans shall not exceed the limitations on distributions of dividends set forth in subsections (a) and (c) above. In this regard, the limitations under subsections (a) and (c) shall be allocated among the two plans for a Participant by multiplying such limitation by a percentage derived by dividing the total of ESOP portion under each plan by the total ESOP portions under both plans (or, if so determined by the Company, by dividing the total ESOP Account under each plan by the total ESOP Account under both plans). 15.4 ADDITIONAL ALLOTMENTS. All active Employee-Participants will be deemed to have elected to make additional Salary Reduction allotments similar to those elected under Section 4.1 ("Additional Allotments") for each calendar year unless they affirmatively elect (under procedures established by the Company) not to make such allotments at least 15 days prior to the scheduled commencement of any distributions under Section 15.3 above (the "Election Date"). The amount of Additional Allotments deemed to be elected under this Section 15.4 shall be equal to the amount of ESOP dividends distributed to the Participant under Section 15.3 above, but subject to applicable legal limitations, including but not limited to the restrictions of Code Sections 402(g) and 415. Such restrictions shall be applied in the manner determined by the Company in its sole discretion . The amount of Additional Allotments shall be calculated by the Company utilizing uniform methodologies and assumptions established by the Company in its sole discretion. 4 120 15.5 PROVISIONS FOR FURTHER REDUCTION OF ADDITIONAL ALLOTMENTS. A Participant's Additional Allotments shall be further reduced as necessary below the level described in Section 15.4 above so as to limit Additional Allotments to an amount equal to or not exceeding: a. The lesser of (i) the residual of a Participant's gross wages less all deductions other than Additional Allotments or (ii) the maximum further reduction permitted under applicable law. b. Zero, in the event that the Participant does not make allotments pursuant to Section 4.1 of the Plan at the time of any distribution of dividends pursuant to Section 15.3 above. c. Zero, in the event that the Participant's Plan Account is invested in less than one share of MCN Stock immediately prior to the distribution of dividends. 15.6 EMPLOYER CONTRIBUTIONS. Additional Allotments shall not be subject to the limitations on Salary Reduction and Voluntary Deduction allotments described in Section 4.1. In addition, Additional Allotments shall not be treated as Salary Reduction or Voluntary Deduction allotments under Section 4.1 for the purposes of determining Employer contributions under 4.2 and 4.3 of the Plan, and shall be disregarded for these purposes. IN WITNESS WHEREOF, this Amendment has been executed as of this 23rd day of December, 1996. MICHIGAN CONSOLIDATED GAS COMPANY By /s/ Susan K.
