HOUSTON (Reuters) - The chief executive officer of Exxon Mobil Corp <XOM.N>, the world's largest publicly traded oil company, received $29 million in total compensation in 2010, a 6.6 percent increase from the previous year, a regulatory filing showed on Wednesday.

Exxon CEO Rex Tillerson's pay included $2.2 million in salary, a $3.4 million bonus, and stock awards valued at $15.5 million, according to a filing with the U.S. Securities and Exchange Commission.

Factors the company's board considered when awarding Tillerson's pay included a 58 percent increase in earnings, safety results and the completion and integration of Exxon's purchase of U.S. natural gas company XTO Energy Inc.

Exxon's shares rose 7 percent in 2010, underperforming a 12 percent increase in the CBOE index of oil companies <.OIX> and a 13 percent increase in the Standard and Poor's 500 index <.SPX>.

In 2008, the Irving, Texas, company faced a challenge from members of the wealthy U.S. Rockefeller family, who urged the company to name an independent chairman.

John D. Rockefeller founded the Standard Oil Co in 1870, which was a precursor to Exxon Mobil.

Shares of Exxon fell 14 cents to $83.04 in midday trading on the New York Stock Exchange.
