Item 2.  Acquisition or Disposition of Assets.

         On April 12, 1999, the Company entered into a Purchase and Sale
Agreement with Columbia Natural Resources to sell all of the Company's oil and
gas properties in Kentucky, Tennessee and West Virginia (the "Appalachia
Properties") for approximately $28 million effective as of April 1, 1999. The
sale closed on May 12, 1999. The oil and gas properties comprising the
Appalachia Properties represented approximately 15% of the Company's total
proved oil and gas reserves at December 31, 1998. The sales proceeds were used
to reduce the outstanding balance under the Company's credit agreement with a
group of banks which provided for the issuance of letters of credit and
revolving credit loans to the Company (the "Credit Agreement") to approximately
$11 million and for general corporate purposes.

         On April 13, 1999, the Company entered into a Purchase and Sale
Agreement with Prince Minerals, Ltd. to sell certain producing and non-producing
mineral interests ( the "Mineral Properties") for approximately $10 million
effective as of April 1, 1999. The sale closed on April 21, 1999. The producing
portion of the oil and gas properties comprising the Mineral Properties
represented approximately 2% of the Company's total proved oil and gas reserves
at December 31, 1998. The sales proceeds, together with the sales proceeds from
the Appalachia Properties, were used to reduce the outstanding balance under the
Credit Agreement to approximately $11 million.

         On May 10, 1999, the Company entered into a Restated Credit Agreement
with Bank One, Texas, N.A. (the "Bank One Revolver"). The Company borrowed $11
million under the Bank One Revolver and repaid in full the outstanding balance
of $11 million under the Credit Agreement and the Credit Agreement was
