EXXONMOBIL SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

Note 1:  Description of the Plan

General

Active participants in the ExxonMobil Savings Plan ("Savings Plan") are eligible employees of Exxon Mobil Corporation ("ExxonMobil" or "Company") and certain affiliated employers.  The terms and conditions of the Savings Plan are contained in the ExxonMobil Common Provisions document, the ExxonMobil Savings Plan document, and the ExxonMobil Savings Trust document (collectively, the "Plan Document").  The Savings Plan is an "employee pension benefit plan" described in Section 3(2) of the Employee Retirement Income Security Act of 1974 ("ERISA") and also a "defined contribution plan" described in Section 3(34) of ERISA.  In addition, effective February 8, 2002, the entire Savings Plan was designated an Employee Stock Ownership Plan ("ESOP"), a plan designed to invest primarily in employer securities.

Contributions

The Savings Plan permits participant contributions of up to 20% of compensation and, prior to 2007, a 100% Company match was made on the first 6% of compensation contributed by the participant.  Prior to 2007, participants could receive up to an additional 1% Company match on the 6% of compensation if the participant elected for the Company match to be directed to the Stock Match Account ("SMA").  Prior to 2007, the restriction on the SMA stipulated that 75% of the assets in the SMA must be invested in ExxonMobil stock.  

Effective January 1, 2007, all active participants began receiving a Company match of 7% of compensation on the first 6% of compensation contributed by them, regardless of how the Company match is directed.  Also effective January 1, 2007, the SMA became fully diversifiable.  

Employees who are at least age 50 during the plan year and who maximize their before-tax contributions may elect to make additional pretax ("catch-up") contributions.  More details of all types of contributions may be found in the Plan Document.

Vesting

Participants are immediately vested in their contributions and all earnings.  Company contributions vest at 100% upon the earliest of completion of 3 years of vesting service, reaching age 65 while employed, or upon death of the participating employee.

Forfeitures

During 2006, $1 million were forfeited by terminating employees and used to offset future employer contributions.

Other Plan Provisions

The Savings Plan was amended in February 2006 in response to the Gulf Opportunity Zone Act of 2005 (GOZA) passed by U.S. Congress to respond to the financial hardships experienced by victims of Hurricanes Katrina, Rita, and Wilma.  Provisions of the Savings Plan amendment for qualifying employees include penalty-free distributions up to $100,000 for active employees and suspension of loan repayments until January 2007.

Other Savings Plan provisions including eligibility, enrollment, participation, forfeiture, loans, benefit payments (including withdrawals and distributions), and investment options are described in the Plan Document.

NOTES TO FINANCIAL STATEMENTS

Plan Termination

The Company may terminate or amend the Savings Plan at any time.  In the event of termination, the net assets of the Savings Plan will be distributed in accordance with the Employee Retirement Income Security Act of 1974.

Note 2:  Accounting Policies

Basis of Accounting

The financial statements of the Savings Plan are presented on the accrual basis. Benefit payments are reported when paid.

Investment Valuation and Income Recognition

Investments are stated at fair value.  Fair values are based on quoted prices as of the date of the financial statements, or if market quotations are not readily available, upon estimated values obtained from a major investment securities firm. At December 31, 2005, the Common Asset Fund included certain guaranteed investment contracts ("GICs") which were stated at contract value, which approximated fair value, representing the original cost, plus interest (based upon the crediting rates of the underlying contracts) reduced by administration fees, transfers out, and withdrawals.  There were no reserves against contract value for credit risk of the contract issuer or otherwise.  The average crediting interest rate of these GICs for the year ended December 31, 2005 was 5.3%.  The annualized crediting interest rate at December 31, 2005 was 5.9%.  Crediting rates fluctuate with the activities of the underlying contracts.  There was no minimum crediting interest rate.  There are no GICs at December 31, 2006.

Under the terms of its trust agreement, the Savings Plan engaged in an authorized form of security lending activities during the years ended December 31, 2006 and 2005.  The market value of securities on loan and the collateral held at The Northern Trust Company at December 31, 2006 were $470 million and $481 million, respectively.  The market value of securities on loan and the collateral held at The Northern Trust Company at December 31, 2005 were $376 million and $385 million, respectively.  In accordance with the Securities Lending Agreement, the market value of the collateral held is required to be 100% of the market value of government securities lent and 102% for all other securities lent.  Collateral held consists of cash, letters of credit, and government securities.  At December 31, 2006 and 2005, the market value of all collateral held was at least 102%.  The securities on loan are reflected in the Statement of Net Assets Available for Benefits and the Schedule of Assets (Held at End of Year) at December 31, 2006 and 2005.

Purchases and sales of securities are recorded on a trade-date basis.  Dividends are recorded on the ex-dividend date.

Net appreciation and depreciation in the current value of investments includes realized gains and losses on investments sold or disposed of during the year and unrealized gains and losses on investments held at year end.

Participant loans represent the outstanding principal balances of the loans and are valued at cost, which approximates current value.

The Savings Plan is subject to normal risks associated with international and domestic debt and equity markets, including the investment in ExxonMobil common stock.

NOTES TO FINANCIAL STATEMENTS

Transfers in include participant-initiated rollovers of certain distributions from other tax-qualified plans into the Savings Plan.  Transfers out include plan-to-plan transfers of the balances of former ExxonMobil employees who became employees of the Infineum USA, L.P. joint venture.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets available for benefits and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period.  Actual results could differ from those estimates.

Note 3:  Related-Party Transactions

During 2006, certain Savings Plan investments were units of various funds managed by The Northern Trust Company.  The Northern Trust Company also provided custodial and other fiduciary services to the Savings Plan during the plan year and, therefore, purchases and sales of these investments qualified as party-in-interest transactions.

Note 4:  Tax Status

The Internal Revenue Service has determined and informed the Savings Plan administrators by a letter dated November 14, 2002, that the Savings Plan is qualified and the trusts established under the Savings Plan are tax-exempt, under the appropriate sections of the Internal Revenue Code ("Code").  The Savings Plan has been amended since receiving the determination letter. However, counsel for the Company believes that these amendments have not adversely affected the Savings Plan's qualified status and the related trust's tax-exempt status as of the financial statement date.

Note 5:  Expenses

Investment income from all sources is stated net of administrative expenses, which include brokerage fees on purchases and sales of ExxonMobil common stock, management fees, and brokerage commissions.  Savings Plan administration expenses, to the extent not paid by the Company, are charged to and paid from the Savings Plan's assets.  Administrative expenses are recorded when incurred.

Note 7:  Plan Merger

The Paxon Polymer Company, L.P. II Savings Plan, the Paxon Polymer Company, L.P. II Hourly Savings Plan, and the Advanced Elastomer Systems, Inc. Retirement Savings Plan were merged with the Savings Plan effective December 1, 2006.  At that time, the merged plans' net assets of $55 million were transferred to the Savings Plan.

Report of Independent Registered Public Accounting Firm

To the Participants and Administrator of the ExxonMobil Savings Plan:

In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the ExxonMobil Savings Plan (the “Plan”) at December 31, 2006 and 2005, and the changes in net assets available for benefits for the year ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America.  These financial statements are the responsibility of the Plan’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.  We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole.  The supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  This supplemental schedule is the responsibility of the Plan's management.  The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.
