Entry
      into a Material Definitive Agreement.
On
      September 7, 2006, we and our 99% subsidiary, American Real Estate Holdings
      Limited Partnership, entered into an Exclusivity Agreement and Letter of Intent,
      or the Letter, with Riata Energy, Inc., relating to a potential transaction
      pursuant to which Riata would obtain an option to acquire all of the issued
      and
      outstanding membership interests of NEG Oil & Gas LLC, our indirect
      wholly-owned subsidiary, or the Transaction.
The
      consummation of the Transaction is subject to the satisfaction of several
      conditions, including the negotiation, execution and delivery of definitive
      agreements within 70 days from the date of the execution of the
      Letter.
The
      Letter sets forth certain proposed terms with respect to the Transaction,
      including a proposed purchase price of approximately $1.519 billion, which
      includes the assumption of third party debt obligations, approximately $1.025
      billion of cash and 12.8 million shares of Riata common stock.
The
      Letter provides for a 70-day exclusivity period, during which we and certain
      of
      our affiliates have agreed not to solicit, negotiate or accept competing
      proposals.
Riata
      is
      a working interest owner and the operator of a majority of the Longfellow
      Ranch area oil and gas properties. Longfellow Ranch is the single largest oil
      and gas property owned by NEG Oil &Gas.
The
      description set forth above is qualified in its entirety by the Letter, a copy
      of which is filed as Exhibit 10.1 to this report and incorporated by
      reference.
