Bankruptcy and Restructuring

In re TXCO Resources Inc., Chapter 11 Bankruptcy Case No. 09-51807, pending in the United States Bankruptcy Court for the Western District of Texas, San Antonio Division
Lead counsel to an exploration and production company who were Debtors in jointly administered chapter 11 bankruptcy case. Cox Smith began to assist TXCO’s management in negotiations with their lenders beginning in March 2009. Once a commitment for post-petition financing was obtained in an amount sufficient to avoid the need for immediate liquidation, Chapter 11 was filed on May 17, 2009. Cox Smith played an instrumental role throughout the bankruptcy case, including obtaining approval of the $32,000,000 in debtor-in-possession financing over numerous objections, putting in place a sale process, introducing potential purchasers, and ultimately negotiating the terms of a sale for approximately $310,000,000 of significantly all of the assets of debtors, which provided for the payment in full of the creditors’ claims with interest and a multi-million dollar return to equity.
