On September 28, 2012, pursuant to the terms of the previously-announced Agreement and Plan of Merger dated as of June 3, 2012 (the "Merger Agreement"), by and among Forestar Group Inc., a Delaware corporation ("Forestar"), CREDO Petroleum Corporation, a Delaware corporation ("Credo"), and Longhorn Acquisition Inc., a Delaware corporation and a wholly owned subsidiary of Forestar ("Merger Sub"), Forestar completed its acquisition of Credo via the merger of Merger Sub with and into Credo, with Credo continuing as the surviving corporation and becoming a wholly owned subsidiary of Forestar (the "Merger"). Upon completion of the Merger, Credo's name was changed to Forestar Petroleum Corporation.

At the effective time of the Merger, each outstanding share of Credo's common stock, other than shares held in Credo's treasury, was cancelled and converted into the right to receive $14.50 per share in cash, without interest. Each option to purchase Credo's common stock that was outstanding as of the effective time of the Merger was cancelled in exchange for the right to receive the excess of $14.50 over the exercise price of such option, less applicable taxes required to be withheld.

The aggregate amount of the merger consideration was approximately $146 million. Forestar financed the transaction using a portion of its existing balance of cash, cash equivalents and short-term investments and borrowings under its Credit Agreement (as defined in Item 2.03 below).

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is incorporated by reference.
