SAN DIEGO, Dec 14, 2009 (BUSINESS WIRE) --

Robbins Umeda LLP has commenced an investigation into possible breaches of fiduciary duty and other violations of state law by members of the Board of Directors of XTO Energy Inc. ("XTO") in connection with its decision to merge with Exxon Mobile Corporation ("Exxon"). XTO and Exxon announced their agreement to merge the companies on Monday, December 14, 2009. Under the terms of the merger agreement, Exxon has agreed to exchange 0.7098 common shares for each common share of XTO. This exchange ration is based on the closing share prices of Exxon and XTO on December 11, 2009. XTO and Exxon expect to complete the transaction in the second quarter of 2010.

Robbins Umeda LLP's investigation concerns whether the consideration to be received by XTO shareholders is fair and whether the directors and special committee members have acted in the shareholders' best interests in connection with the sale process.
