Exxon Mobil Corporation

Extended Provisions for Restricted Stock Unit Agreements – Settlement in Shares

1. Effective Date and Credit of Restricted Stock Units. If Xxxxxxx completes, signs, and returns the signature page of this Agreement to the Corporation in Dallas County, Texas, U.S.A. on or before March 9, 2012, this Agreement will become effective the date the Corporation receives and accepts the signature page in Dallas County, Texas, U.S.A. After this agreement becomes effective, the Corporation will credit to Grantee the number of restricted stock units specified on the signature page. Subject to the terms and conditions of this Agreement, each restricted stock unit (“unit”) will entitle Grantee to receive in settlement of the unit one share of the Corporation’s common stock.

2. Conditions. If credited, the units will be subject to the provisions of this Agreement, and to such regulations and requirements as the administrative authority of the Program may establish from time to time. The units will be credited to Grantee only on the condition that Grantee accepts such provisions, regulations, and requirements.

3. Restrictions and Risk of Forfeiture. During the applicable restricted periods specified in section 4 of this Agreement,

(a) the units under restriction may not be sold, assigned, transferred, pledged, or otherwise disposed of or encumbered, and any attempt to do so will be null and void; and

(b) the units under restriction may be forfeited as provided in section 6.

4. Restricted Periods. The restricted periods will commence when the units are credited to Grantee and, unless the units have been forfeited earlier under section 6, will expire as follows, whether or not Grantee is still an employee:

(a) with respect to 50% of the units, on November 30, 2016; and

(b) with respect to the remaining units, on the later to occur of

(i) November 30, 2021, or

(ii) the first day of the calendar year immediately following the year in which Grantee terminates;

except that

(c) the restricted periods will automatically expire with respect to all shares on the death of Xxxxxxx.

5. No Obligation to Credit Units. The Corporation will have no obligation to credit any units and will have no other obligation to Grantee with respect to the subject matter of this Agreement if Grantee fails to complete, sign, and return the signature page of this Agreement on or before March 9, 2012. In addition, whether or not Grantee has completed, signed, and returned the signature page, the Corporation will have no obligation to credit any units and will have no other obligation to Grantee with respect to the subject matter of this Agreement if, before the units are credited:

(a) Grantee terminates (other than by death) before standard retirement time within the meaning of the Program, except to the extent the administrative authority of the Program determines Grantee may receive units under this Agreement; or

(b) Grantee is determined to have engaged in detrimental activity within the meaning of the Program; or

(c) Grantee fails to provide the Corporation with cash for any required taxes due upon crediting the units, if Grantee is required to do so under section 7.

6. Forfeiture of Units After Crediting. Until the applicable restricted period specified in section 4 has expired, the units under restriction will be forfeited or subject to forfeiture in the following circumstances:

Termination

If Grantee terminates (other than by death) before standard retirement time within the meaning of the Program, all units for which the applicable restricted periods have not expired will be automatically forfeited as of the date of termination, except to the extent the administrative authority determines Grantee may retain units issued under this Agreement.

Detrimental activity

If Grantee is determined to have engaged in detrimental activity within the meaning of the Program, either before or after termination, all units for which the applicable restricted periods have not expired will be automatically forfeited as of the date of such determination.

Attempted transfer

The units are subject to forfeiture in the discretion of the administrative authority if Grantee attempts to sell, assign, transfer, pledge, or otherwise dispose of or encumber them during the applicable restricted periods.

Applicable law

The units are subject to forfeiture in whole or in part as the administrative authority deems necessary in order to comply with applicable law.

7. Taxes. Notwithstanding the restrictions on transfer that otherwise apply, the Corporation in its sole discretion may withhold units or shares, either at the time of issuance, at the time the applicable restricted periods expire, or at any other time in order to satisfy any required withholding, social security, and similar taxes or contributions (collectively, “required taxes”). Withheld units or shares may be retained by the Corporation or sold on behalf of Grantee. If the Corporation does not withhold units or shares to satisfy required taxes, in the alternative the Corporation may require Grantee to deposit with the Corporation cash in an amount determined by the Corporation to be necessary to satisfy required taxes. Notwithstanding any other provision of this Agreement, the Corporation will be under no obligation to credit units or to deliver shares to Grantee in settlement of any units if Grantee fails timely to deposit such amount with the Corporation. The Corporation in its sole discretion may also withhold any required taxes from dividends paid on the units.

8. Form of Units; No Shareholder Status. The units will be represented by book-entry credits in records maintained by or on behalf of the Corporation. Units will be unfunded and unsecured promises by the Corporation to deliver shares in the future upon the terms and subject to the conditions of this Agreement. Grantee will not be a shareholder of the Corporation with respect to units prior to the time shares are actually registered in Grantee’s name in settlement of such units in accordance with section 9.

9. Settlement of Units. If and when the applicable restricted period expires with respect to any units, subject to section 7, the Corporation will issue shares, free of restriction and registered in the name of Grantee, in settlement of such units. Such shares will be delivered promptly after such expiration to or for the account of Grantee either in certificated form or by book-entry transfer in accordance with the procedures of the administrative authority in effect at the time.

10. Change in Capitalization. If during the applicable restricted periods a stock split, stock dividend, or other relevant change in capitalization of the Corporation occurs, the administrative authority will make such adjustments in the number of units credited to Grantee, or in the number and type of securities deliverable to Grantee in settlement of such units and used in determining dividend equivalent amounts, as the administrative authority may determine to be appropriate. Any resulting new units or securities credited with respect to previously credited units that are still restricted under this Agreement will be delivered to and held by or on behalf of the Corporation and will be subject to the same provisions, restrictions, and requirements as those previously credited units.

11. Limits on the Corporation’s Obligations. Notwithstanding anything else contained in this Agreement, under no circumstances will the Corporation be required to credit any units or issue or deliver any shares in settlement of units if doing so would violate any law or listing requirement that the administrative authority determines to be applicable, or if Grantee has failed to provide for required taxes pursuant to section 7.

12. Receipt or Access to Program. Xxxxxxx acknowledges receipt of or access to the full text of the Program.

13. Dividend Equivalents. The Corporation will pay to Grantee cash with respect to each credited unit corresponding in amount, currency, and timing to cash dividends that would be payable with respect to a share of common stock outstanding on each record date that occurs during the applicable restricted period. Alternatively, the administrative authority may determine to reinvest such dividend equivalents in additional units which will be held subject to all the terms and conditions otherwise applicable to units under this Agreement.

14. Addresses for Communications. To facilitate communications regarding this Agreement, Xxxxxxx agrees to notify the Corporation promptly of changes in current mailing and email addresses. Communications to the Corporation in connection with this Agreement should be directed to the Incentive Processing Office at the address given on the signature page of this Agreement, or to such other address as the Corporation may designate by further notice to Grantee.

This data includes Xxxxxxx’s name, age, date of birth, contact information, work location, employment status, tax status, social security number, salary, nationality, job title, share ownership, and details of incentive awards granted, cancelled, vested or unvested, and related information.

Such data will at all times be held in accordance with applicable laws, regulations, and agreements.

16. No Employment Contract or Entitlement to Other or Future Awards. This Agreement, the Corporation’s incentive programs, and Xxxxxxx’s selection for incentive awards do not imply or form a part of any contract or assurance of employment, and they do not in any way limit or restrict the ability of Grantee’s employer to terminate Xxxxxxx’s employment. Xxxxxxx acknowledges that the Corporation maintains and administers its incentive programs entirely in its discretion and that Grantee is not entitled to any other or future incentive awards of any kind in addition to those that have already been granted.
