A Member's Accrued Benefit shall be equal to the greater of (i) the monthly benefit earned by the Member under the Plan immediately prior to its amendment and restatement effective February 22, 1996 based on service, compensation and other factors then prevailing or (ii) an amount of monthly retirement income payable at the Member's Normal Retirement Date in the form of a single life annuity equal to the Member's Average Monthly Earnings multiplied by the applicable percentage determined in accordance with Appendix A hereto based upon the Member's years of Benefit Calculation Service but reduced by the offsets described in Section 5.02. If a Member has a fractional year of Benefit Calculation Service, such fraction shall be counted for purposes of determining the "Standard Accrual Rate" but not the "Retroactive Cliff Bonus - 6 - 8 Accrual." For example, if a Member has 9.5 years of Benefit Calculation Service, his "Cumulative Accrual" would be 14.25 percent (13.5 percent + [.5 x 1.5 percent]). 5.02 Offsets. A Member's Accrued Benefit shall be reduced and offset by the following amounts: (a) the monthly amount of retirement income payable to the Member under the Salaried Pension Plan and any other defined benefit pension plan maintained by the Company or any of its affiliates or by USX or any of its affiliates; and (b) 50 percent of the Member's Primary Insurance Amount. 5.03 Commencement of Benefits. The benefits payable under this Plan shall commence to be paid at the same time as benefits are to be paid to the Member or his or her Beneficiary under the Salaried Pension Plan. If a Member's benefits commence before attainment of age 62, the Member shall be entitled to an amount equal to his Accrued Benefit otherwise determined above reduced by one-half of one percent (1/2 percent) for each month by which his date of benefit commencement precedes the first day of the month coincident with or immediately following the date that the Member will attain age 62. 5.04 Vesting of Accrued Benefit. (a) A Member shall acquire a fully vested interest in his Accrued Benefit upon his death or attainment of age 65 while in the employ of the Company. (b) Whenever the employment of a Member terminates before Retirement and for reasons other than death, he shall be entitled to a nonforfeitable (vested) percentage of his Accrued Benefit, in accordance with the following table, based on his full years of Vesting Service as of the date of termination of employment: Full Years of Vested Percentage Vesting Service of Accrued Benefit --------------- ------------------ Less than 5 years 0 percent 5 years or more 100 percent - 7 - 9 Notwithstanding the foregoing, upon and following a Change of Control, a Participant shall be 100 percent vested in his Accrued Benefit. 5.05 Distribution of Benefits. Each Member may elect to receive monthly retirement income in one of the alternative forms listed in Section 5.06. The timing of such elections shall be in accordance with Section 5.07. Each of the alternative forms shall be the Actuarial Equivalent of the monthly retirement income payable in the single life annuity form. In the absence of an election as to the form of benefit payment, in the case of a Member who is not married on his annuity starting date, the Member's Accrued Benefit shall be payable in the single life annuity form. In the absence of an election as to the form of benefit payment, in the case of a Member who is married on his annuity starting date, his Accrued Benefit shall be paid in the form described in Section 5.06(b). 5.06 Form of Payment. Subject to the limitations of subsection (e) below, the alternative forms of payment available under the Plan for all types of retirement benefits are as follows: (a) Single Life Annuity Form. A monthly income continuing for the life of the Member. (b) Qualified Joint and Survivor Annuity. A monthly income payable for the lifetime of the Member and continuing thereafter in an amount fifty percent (50 percent) as large to the Member's spouse for the lifetime of said spouse. (c) Contingent Annuitant Option. A monthly income payable for the lifetime of the Member and continuing thereafter in an amount fifty percent (50 percent) or one hundred percent (100 percent) as great, as elected by the Member, to a Co-Pensioner designated in writing by the Member for such Co-Pensioner's life. Should the Co-Pensioner named by the Member die prior to the Member's annuity starting date, this election shall be void and a single life annuity shall be paid as if election of this optional form had never been made. Should the Co-Pensioner die after payment of the Member's Accrued Benefit has commenced, no alternative Co-Pensioner can be named. (d) Lump Sum Option - A Member may elect, in lieu of the forms of payment set forth in subsections (a), (b) and (c) above, to receive a lump sum distribution of - 8 - 10 his vested Accrued Benefit in an amount equal to the Actuarial Equivalent of such vested Accrued Benefit. (e) Limitation. Notwithstanding any other provision of this Plan to the contrary, if an annuity form of distribution is payable to the Member under the terms of the Salaried Pension Plan, then the same form of annuity payout shall be applicable to the Member's Accrued Benefit hereunder. 5.07 Timing of Benefit Elections. Each Member shall make his election as to the form of benefit distribution before the later of (i) the Member's 55th birthday and (ii) 30 days after the effective date of such Member's initial eligibility under the Plan. Such election shall be irrevocable except as provided in Section 5.10 and as follows: (a) If the change is made at least 13 months prior to the date of termination of employment, the Member may change his election from any optional benefit form to any other optional benefit form. (b) If the change is not made at least 13 months prior to the date of termination of employment, the Member may change his election from a lump sum to an annuity or from an annuity to a lump sum (but not from one annuity form to another), but in such event the Member shall forfeit ten percent (10 percent) of his Accrued Benefit, determined as of the date the new election is effective. 5.08 Hardship Withdrawal. Following Retirement, a Member may, in the event of a Financial Hardship, request a withdrawal of all or a portion of his Accrued Benefit. The request shall be made in a time and manner determined by the Administrative Committee, shall not be for a greater amount than the amount required to meet the Financial Hardship, and shall be subject to approval by the Administrative Committee. 5.09 Change in Control. If within two years after the occurrence of a Change in Control either (i) the Plan is terminated or (ii) a Member's employment with the Company is terminated by the Company without Cause, an additional three years will be added to the Member's Benefit Calculation Service for purposes of calculating the Member's Accrued Benefit, except for purposes of determining the Member's eligibility for the 10 percent "Retroactive Cliff Bonus Accrual" at 10 years of Benefit Accrual Service and the 12.5 percent "Retroactive Cliff Bonus Accrual" at 15 years - 9 - 11 of Benefit Accrual Service (as described in Appendix A), and the Member's Accrued Benefit so calculated shall be paid to the Member in a lump sum distribution within 30 days of the date of termination. 5.10 Change in Distribution Form. Following the occurrence of a Change in Control, a Member or Beneficiary who is receiving an annuity benefit shall be entitled to elect to convert such annuity into an immediate lump sum distribution of the Actuarial Equivalent of his Accrued Benefit, as adjusted for any benefit payments made prior to the date of such conversion; provided that, as a condition of such conversion, the Member or Beneficiary, as the case may be, shall forfeit an amount equal to six percent (6 percent) of such lump sum benefit. If a Change in Control has not occurred, a Member or Beneficiary shall be entitled to elect such a conversion from an annuity to a lump sum, but the forfeited amount shall equal ten percent (10 percent) of the lump sum benefit. Article VI - Survivor Benefits 6.01 Pre-Retirement Survivor Benefit for Vested Member. In the case of any Member who dies prior to his annuity starting date when he is vested in his Accrued Benefit, the Member's Beneficiary shall be entitled to a survivor benefit, payable as follows: (a) If such Member was eligible to immediately commence receipt of his Accrued Benefit as of the date of his death, such survivor benefit shall be a monthly income payable for the life of the Beneficiary, commencing on the first day of the month immediately following the Member's date of death equal to the benefit that would have been payable to the Beneficiary had the Participant retired on the day before death, and elected immediate commencement of benefits in a joint and 50 percent survivor annuity form under Section 5.06(c). The last monthly payment shall be made for the month in which the death of such Beneficiary occurs. (b) If such Member was not eligible to immediately commence receipt of his Accrued Benefit hereunder as of the date of his death, such survivor benefit shall be a monthly income payable for the life of the Beneficiary, beginning with the first day of the month in which the Member could have elected - 10 - 12 immediate benefits had he survived ("earliest commencement date"), equal to the benefit that would have been payable to the Beneficiary had the Member terminated employment on his date of death (except where termination of employment occurred prior to his death, the Member's date of termination of employment shall be used) and then survived and retired on the earliest commencement date and elected immediate commencement of benefits in a joint 50 percent and survivor annuity form under Section 5.05(c). The last monthly payment shall be made for the month in which the death of such Beneficiary occurs. 6.02 Post-Retirement Survivor Benefit.

Article VII - Amendment and Termination The Company, by action of the Board, may modify, alter, amend or terminate the Plan in whole or in part, except to the extent that such action would result in the reduction of the Accrued Benefit of any Member. Notwithstanding the foregoing, the Company may not amend or terminate the Plan within two (2) years following a Change in Control without the consent of a majority of the Participants. Article VIII - Miscellaneous 8.01 Withholding. The Member or the Beneficiary shall make appropriate arrangements with the Company for satisfaction of any federal, state or local income tax withholding requirements and Social Security or other employee tax requirements applicable to the payment of benefits under the Plan.

The rights of a Member or his or her Beneficiary to receive payment of any benefits under the Plan shall be and remain no greater than the rights of an unsecured general creditor of the Company. In the event the Company establishes a trust, which it may but shall not be required to do, to hold money or other property of the Company in contemplation of paying benefits under - 11 - 13 the Plan, such money or other property shall remain subject to the claims of creditors of the Company. 8.03 Nonassignability.
