Item 2.06.         Material Impairments

On May 5, 2010, Ridgewood Energy X Fund, LLC (the “Fund”) was informed by the operator that the Targa Project, an exploratory well, did not have commercially productive quantities of either gas or oil and has been determined to be an unsuccessful well, or dry hole.  The Fund owns a 2% working interest in the Targa Project.

As a result of the dry hole, the Fund incurred approximately $2.2 million of charges during the second quarter of 2010.  The Fund does not expect this dry hole to result in any significant additional expenditures.
