Dividends
Dividends on Common Stock, as declared by the Board of Directors, are normally paid on the 10th day of March, June, September and December.

Dividend Checks Not Received / Electronic Deposit
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 National City Bank by phone or in writing to issue a replacement check. You may contact National City Bank to authorize electronic deposit of your dividends or interest into your bank account.

Section 302 Certifications and NYSE CEO Certification
Marathon Oil Corporation has filed the certifications of its Chief Executive Officer and Chief Financial Officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 as Exhibits 31.1 and 31.2 to its Annual Report on Form 10-K for the year ended December 31, 2007. In May 2007, Marathon's Chief Executive Officer, as required by Section 303A.12(a) of the NYSE Listed Company Manual, submitted his certification to the NYSE that he was not aware of any violation by Marathon of the NYSE's corporate governance listing standards.

 

Dividend Reinvestment and Direct Stock Purchase Plan
The Dividend Reinvestment and Direct Stock Purchase Plan provides stockholders with a convenient way to purchase additional shares of Marathon Oil Corporation Common Stock without payment of any brokerage fees or service charges through investment of cash dividends or through optional cash payments. Stockholders of record can request a copy of the Plan Prospectus and an authorization form from National City Bank. Beneficial holders should contact their brokers.

 

Lost Stock Certificate
If a stock certificate is lost, stolen or destroyed, notify National City Bank in writing so that a stop transfer can be placed on the missing certificate. National City Bank will send you the necessary forms and instructions for obtaining a replacement certificate. You may be required to obtain and pay for the cost of an indemnity bond. If you find the missing certificate, notify National City Bank in writing 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.

 

Taxpayer Identification Number
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, National City Bank may be required to withhold 28 percent for federal income taxes from your dividends.

 

Address Change
It is important that you notify National City Bank immediately, by phone, in writing or by fax, when you change your address. As a convenience, you also may indicate an address change on the stub of your quarterly dividend check. Seasonal addresses may be entered for your account.

 

Exchange of Certificate
If you have not done so, we recommend you submit 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 National City Bank.

Cautionary Note and Statement for the Purposes of the Safe Harbor Provisions of the Private Securities Litigation Reform Act of 1995
The United States Securities and Exchange Commission (SEC) permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. In this summary annual report wrap, we use certain terms to refer to reserves other than proved reserves, which the SEC's guidelines strictly prohibit us from including in filings with the SEC. These terms include resources and other similar terms, which are not yet classified as proved reserves. U.S. investors are urged to consider closely the disclosures in our Form 10-K. You can obtain this form from the SEC by calling 1-800-SEC-0330. This summary annual report wrap also contains forward-looking statements about Marathon's four business segments: (1) exploration and production; (2) oil sands mining; (3) integrated gas; and (4) refining, marketing and transportation. Such statements include, but are not limited to, the timing and levels of production from the Alvheim/Vilje development in Norway, the Neptune development in the Gulf of Mexico, the Corrib project in Ireland and other existing and potential developments; future exploration and drilling activity; additional reserves; the estimated startup date of an LNG liquefaction plant and related facilities in Equatorial Guinea, including possible expansion plans and sale of the LNG; potential developments in Angola; potential new leaseholds in Indonesia; potential gas-to-fuels developments; potential production development in Libya; the anticipated commencement or completion date of other expansion projects; a joint venture that would construct and operate ethanol plants; the Garyville refinery expansion; and the common stock repurchase program. Where, in any forward-looking statement, the Company expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, there can be no assurance that the statement of expectation or belief will result or be achieved. These statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. In accordance with the "Safe Harbor" provisions of the Private Securities Litigation Reform Act of 1995, Marathon has included in its attached Form 10-K for the year ended December 31, 2007, cautionary language identifying important factors, though not necessarily all such factors, that could cause future outcomes to differ materially from those set forth in the forward-looking statements.
