      including the pending nature of the announced divestiture of non-core oil and
      gas properties as well as the ability to complete the transaction, the uncertain
      nature of the expected benefits from the divestiture of oil and gas properties,
      the volatility and level of oil and natural gas prices, the availability of
      economically attractive exploration and development and property acquisition
      opportunities and any necessary financing, lower prices realized on oil and
      gas
      sales resulting from our commodity price risk management activities,
      unsuccessful exploration and development drilling, uncertainties inherent in
      projecting future rates of production from drilling activities and acquisitions,
      drilling and operating service availability, uncertainties in cash flow, the
      financial strength of hedge contract counterparties, the negative impact that
      lower oil and natural gas prices could have on our ability to borrow,
      litigation, environmental matters, the potential impact of government
