The purpose of this Plan is to provide additional payments from the general assets of Exxon Mobil Corporation (the "Corporation") to certain persons. The benefits payable under this Plan consist of two types of pension benefits and a disability benefit. The first pension benefit is a benefit based upon the person's final average incentive compensation ("Incentive Pension Benefit"). The second pension benefit restores certain benefits that are accrued under a pension plan sponsored by a non-U.S. affiliate of the Corporation but which are not paid ("Overseas Makeup Benefit"). The disability benefit is based on incentive compensation and is paid in the event of a long-term disability ("Disability Benefit").

A person is eligible to receive Incentive Pension Benefits only if the person becomes a retiree within the meaning of the ExxonMobil Common Provisions ("retiree"):

The amount of a person's Incentive Pension Benefit is determined by multiplying 1.6% of the person's final average incentive compensation by the person's years of pensionable service, and dividing the amount so derived by twelve. The result is expressed in the form of a monthly five-year certain and life annuity for the life of the person commencing at the person's age 65 ("Normal Retirement Age").

(1) Except as provided in paragraph (2) below, it shall be the amount of pension service credited for the person under the ExxonMobil Pension Plan.

(b) upon localization is not credited with pension service under the ExxonMobil Pension Plan for the person’s service with the most recent service-oriented employer, and

the person’s pensionable service shall be the sum of the service credited under the Imperial Plan at the time of the person’s localization plus the pension service credited thereafter to the person under the ExxonMobil Pension Plan.

For the purposes of paragraph (A) above, a person's "final average incentive compensation" shall be determined in accordance with this paragraph (C).

A person's final average incentive compensation is the average of the person's three highest annual bonus awards (including awards of zero, if any) under the Corporation's Incentive Programs awarded on any of the five most recent annual award dates immediately preceding the person's termination of employment.

If a person commences employment with the Corporation or one of its affiliates in connection with a corporate acquisition, incentive compensation paid by the person's former employer that is the equivalent of bonus awards payable under the Corporation's Incentive Program may, in the sole discretion of the management of the Corporation, be taken into account for purposes of determining the person’s final average incentive compensation under this Paragraph (C).

For purposes of this paragraph (C), in determining the amount of a person's annual bonus award, only awards granted under the short-term incentive part of the Incentive Programs as cash and bonus units are considered.

For purposes of this paragraph (C), in determining the amount of a person's annual bonus award, an award to a person characterized by the granting authority as a special one-time bonus is disregarded, unless deemed specifically includable by the granting authority at the time of grant.

If an annual bonus award is granted as bonus units, the maximum settlement value obtainable at the time of the grant shall be used in calculating the value of the award.

If a participant under this Plan is also entitled to payments comparable to the Incentive Pension Benefit for any portion of the same years of pensionable service under a plan of a service-oriented employer, as defined in the ExxonMobil Common Provisions, other than the Corporation, the amount of the Incentive Pension Benefit shall be reduced by the respective amount of such comparable payments. In any given

case, the Plan Administrator may determine the precise amount of this offset and if a conversion of currency computation is required, may follow the process established under the ExxonMobil Pension Plan.

The portion of any Incentive Pension Benefit deriving from a provisionally granted bonus that is subsequently annulled lapses as of the date of such annulment.

(B) the person terminates active participation in the non-U.S. plan and simultaneously becomes a participant in the ExxonMobil Pension Plan or predecessor plan;

(C) as a result of terminating active participant status under the non-U.S. plan, the person loses eligibility for all or a portion of the benefit under the non- U.S. plan accrued prior to termination; and

(D) the amount of the lost benefit is not provided under the terms of the ExxonMobil Pension Plan, the ExxonMobil Supplemental Pension Plan, or otherwise under this Plan.

The amount of the Overseas Makeup Benefit is the amount, expressed as a monthly benefit in the form of a five-year certain and life annuity that is the actuarial equivalent of the lost benefit under the non-U.S. plan. Such amount shall be conclusively determined by the Plan Administrator.

Except as provided under paragraph (B) below, payment of a person's Incentive Pension Benefit and, if applicable, Overseas Makeup Benefit shall occur as soon as practicable following the later to occur of the following:

(2) In the case of a person who, immediately prior to his or her retirement, has a Classification Level of 35 or above ("Key Employee"), the six-month anniversary of the person's retirement.

Notwithstanding the above, a person with a Classification Level of 35 whose retirement is approved prior to February 1, 2021, and occurs prior to May 1, 2021 shall not be considered a Key Employee.

In the case of a person who retires with eligibility for Disability Benefits under article 6 below prior to the first of the month in which the person attains age 55, payment of such benefit shall occur as of the first of the month in which the person attains age 55, or as soon as practicable thereafter.

If a payment under section 4.1 above occurs prior to the month in which the person reaches Normal Retirement Age, it is reduced by applying the early commencement factors specified under the ExxonMobil Pension Plan for a benefit commencing at the person's then age.

Payment of a person's Incentive Pension Benefit or Overseas Makeup Benefit shall be made in a lump sum that is the actuarial equivalent of the five-year certain and life annuity. For this purpose, actuarial equivalence shall be determined by the Plan Administrator using the factors and procedures that are used for the calculation of the lump-sum payment option under the ExxonMobil Pension Plan.

If payment of a Key Employee's Incentive Pension Benefit and/or Overseas Makeup Benefit is delayed for six months following retirement because of the requirement set out in section 4.1(A)(2) above, then instead of the lump-sum benefit calculated under section 4.3 above, the person shall receive a lump-sum benefit equal to the greater of the following:

(A) The lump-sum payment that would otherwise have been calculated for the person under section 4.3 above as if he were not a Key Employee, based on the payment date that would have applied to the individual if he were not a Key employee
