ExxonMobil Pension Plan SPD

About The Pension Plan

This SPD is the summary plan description for the mainstream benefits provided under the ExxonMobil Pension Plan. Descriptions of pension benefits provided by other ExxonMobil sponsored plans or sub-plans of the ExxonMobil Pension Plan are contained in separate summary plan descriptions for each of those specific plans including but not limited to the Retirement Plan of Mobil Oil Corporation, Advanced Elastomer Systems, L.P. Pension Plan for Salaried Employees, and Paxon Hourly and Salaried Pension plans.

This SPD supersedes all previous Pension Plan participant publications. It does not contain all the details. In determining specific benefits, the full Pension Plan provisions, as they exist now or in the future, always govern. Copies of Pension Plan documents are available for your review. The company reserves the right at any time to change in any way or terminate any benefit.

Eligibility for participation in the Pension Plan by represented employees is governed by local bargaining requirements.

Introduction

The two pressing questions about retirement are: How much money will I need and where will I get this money?

Many financial planners believe that in retirement, people need between 70% and 80% of their income just before retirement. The amount you need depends on factors as unique as you are — what you want to do when you retire, your health and your financial obligations. In addition, your retirement income must keep pace with inflation during your retirement.

The company helps you prepare financially for retirement. ExxonMobil's Pension Plan and Savings Plan are designed to work with Social Security and personal savings to provide financial security in retirement for long-term career employees.

The Pension Plan is designed primarily to provide you a monthly benefit from the time of your retirement until your death. This Plan offers additional flexibility — you can choose various payment options for your pension. In addition, the Plan may pay benefits to your survivors in case of your death.

To help you find specific Plan information quickly and easily, this SPD includes these helpful tools:

• Plan at a Glance, a quick user's guide highlighting plan basics.
• Charts and tables throughout the booklet providing information, highlights of plan provisions, etc.

A careful reading of this SPD will help you understand how the Plan works. You may obtain additional information through the sources shown on pages 1 and 2.

Plan at a Glance

Participation and Vesting
Regular, full-time employees automatically begin participating upon employment. In some cases, part-time employees may also participate. You are vested when you have five years of service or reach age 65, whichever comes first. See page 4.

Retiring From ExxonMobil
While you are eligible to receive a pension if your employment ends after you become vested, the benefit is enhanced if you are a retiree. Generally, you become a retiree when you terminate employment as a regular employee and have at least 15 years of service and are age 55 or older. See page 5.

Pension Plan Basics
Your basic pension benefit is determined by a formula that takes into account your service, pay and Social Security benefit. See page 6.

When Your Benefit Can Begin
Benefits are available after your employment ends. Benefits can begin as early as age 50. The amount of your benefit may be adjusted to take into account your age when your benefit begins. See page 9.

How Your Benefit Is Paid
The Plan provides several payment options. Retirees can choose among more options. See page 12.

What Happens When You Die
The Plan pays death benefits in most cases if you die before you begin receiving your benefit. If you die after your pension benefit has started, the payment option you chose determines whether benefits continue. See page 16.

Administrative and ERISA Information
This Plan is subject to rules of the federal government, including the Employee Retirement Income Security Act (ERISA). See page 19.
