Dividends on common stock, as declared by the Board of Directors, are normally paid on the 10th day of March, June, September and December.
Form 1099-DIV will be mailed to shareholders by Computershare no later than January 31, if you were paid at least $10.00 in dividends.
If you do not receive your dividend check on the appropriate payment date, we suggest that you wait at least 10 days after the payment date to allow for any delay in mail delivery. After that time, advise Computershare to issue a replacement check. You may contact Computershare to authorize electronic deposit of your dividends or interest into your bank account.
The Dividend Reinvestment and Direct Stock Purchase Plan (the "Plan") provides shareholders with a convenient way to purchase additional shares of Marathon Oil Corporation Common Stock without payment of any brokerage fees or service charges through the investment of cash dividends or through optional cash payments. The Plan was temporarily suspended in November 2008. We have reinstituted the Plan, as amended and restated, effective March 10, 2009. Effective October 12, 2009, the administrator for the Plan changed to Computershare Trust Company, N.A. Computershare Inc. acts as service agent to Computer Trust Company, N.A. under the Plan.
For further information about the Plan, please see the "Letter to Participants." A copy of the Plan Prospectus, Notice of Plan Administrator Change and Authorization Form can be found on the Dividend Reinvestment and Direct Stock Purchase Plan page. Stockholders of record may also request a copy of the Plan Prospectus and Authorization Form by contacting the Company's stock transfer agent, Computershare at 1-888-843-5542 or web.queries@computershare.com. Beneficial holders should contact their brokers.

It is important that you notify Computershare immediately when you change your address. As a convenience, you also may make your address change online via Computershare's Investor Centre™.
Federal law requires that each stockholder provide a certified Taxpayer Identification Number (TIN) for his/her stockholder account. For individual stockholders, your TIN is your Social Security Number. If you do not provide a certified TIN, Computershare may be required to withhold 28 percent for federal income taxes from your dividends.
If you have not done so, we recommend that you return any USX Corporation or United States Steel Corporation common stock certificates, which were issued prior to May 7, 1991, in exchange for certificates for Marathon Oil Corporation common stock. Certificates should be sent to Computershare. Since Marathon Oil Corporation does not issue stock certificates, your Marathon Oil Corporation shares will be put in direct registration in your account at Computershare. Computershare will send to you a Direct Registration Statement reflecting your shares of Marathon Oil Corporation in your account.
If a stock certificate is lost, stolen, or destroyed, notify Computershare so that a "stop transfer" can be placed on the missing certificate. Computershare will send you the necessary forms and instructions for obtaining a replacement which will be issued in direct registration form. You may be required to obtain and pay for the cost of an indemnity bond. If you find the missing certificate, notify Computershare immediately so that the stop transfer can be removed. To avoid loss, theft, or destruction, we recommend that you keep your certificates in a safe place, such as a safe deposit box at your bank.
