ITEM 2.  Acquisition or Disposition of Assets

             On May 30, 1997, the Company consummated the sale of its Rusk
County, Texas oil and gas properties and pipeline to Union Pacific Resources
Company ("UPRC") and Union Pacific Interstate Pipeline Company ("UPIPC"),
respectively. The assets sold include approximately 8150 net acres, 115
producing oil and gas wells and a 74 mile pipeline which gathers gas from the
producing wells and delivers to a pipeline owned by Lone Star Gas Company. The
reserves associated with the oil and gas properties that were sold comprise
approximately 84% of the Company's proved reserves. The Company still owns its
non-Texas oil and gas properties and its gas sales contract with Lone Star Gas
Company. That contract expires on May 31, 1999.

             The purchase price received by the Company was $54,758,531 and
consisted of $50,183,531 cash, $1,575,000 of liabilities assumed by UPRC and
$3,000,000 of prepaid gas transportation. The gas transportation prepayment
relates to natural gas that the Company is required to supply to Lone Star Gas
Company through May 31, 1999. Although the purchase price will be increased or
decreased through post closing adjustments within the next 160 days, the net
amount of such post closing adjustments is not expected to be significant.

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF THE COMPANY

      The following pro forma consolidated balance sheet and statements of
operations of the Company illustrate the estimated effects of the sale (the
"Asset Sale") of the Company's Rusk County, Texas oil and gas properties and
pipeline to Union Pacific Resources Company ("UPRC") and Union Pacific
Intrastate Pipeline Company ("UPIPC"), respectively, as if the Asset Sale had
occurred on (i) March 31, 1997 for balance sheet purposes, (ii) October 1, 1996
for purposes of the statement of operations for the six months ended March 31,
1997, and (iii) October 1, 1995 for purposes of the statement of operations for
the year ended September 30, 1996. The pro forma consolidated financial
statements assume that the post closing adjustments to the purchase price will
not be significant.

      THE PRO FORMA CONSOLIDATED STATEMENTS OF THE COMPANY DO NOT PURPORT TO
REPRESENT WHAT THE COMPANY'S FINANCIAL POSITION OR RESULTS OF OPERATIONS WOULD
ACTUALLY HAVE BEEN IF THE ASSET SALE IN FACT HAD OCCURRED ON SUCH DATES OR TO
PROJECT THE COMPANY'S FINANCIAL CONDITION OR RESULTS OF OPERATIONS AS OF ANY
FUTURE DATE OR FOR ANY FUTURE PERIOD. The pro forma adjustments are based upon
available information and upon certain assumptions that the Company believes are
reasonable under the circumstances. The pro forma consolidated financial
statements and accompanying notes should be read in conjunction with the
historical consolidated financial statements of the Company and notes thereto
and the other financial information regarding the Company included in filings
with the Securities and Exchange Commission made by the Company.

General
- --------
     Gives effect to the Asset Sale as though it occurred October 1, 1996.

     1.  Reflects changes in operating income items other than depletion and
         depreciation as a result of the Asset Sale as follows:

         (a) Reflects replacement of equity gas (sold in Asset Sale) with
             purchased gas, i.e., the gas that was previously owned is now being
             purchased from the buyer.

         (b) Reflects loss of operating fees attributable to oil and gas
             properties sold in Asset Sale.

         (c) Reflects reduction in operating and general and administrative
             costs attributable to assets sold.

         (d) Reflects amortization of two years of prepaid gas transportation
             received as part of the purchase price.

         (e) Reflects loss of oil and gas sales from oil and gas properties
             sold.

     2.  Reflects reduction in depletion for oil and gas properties and in
         depreciation for pipeline as a result of the Asset Sale.

     3.  Reflects elimination of interest expense since a portion of the
         proceeds from the Asset Sale were assumed used to liquidate the
         Company's bank debt.

     In accordance with the guidelines of the Securities and Exchange
Commission, interest or other income has not been imputed on the remaining cash
proceeds received by the Company in the Asset Sale nor have such cash proceeds
been assumed to have been spent for other purposes such as repurchasing shares
of the Company's stock or additional investments.

General
- ---------
     Gives effect to the Asset Sale as though it occurred October 1, 1995.

     1.  Reflects changes in operating income items other than depletion and
         depreciation as a result of the Asset Sale as follows:

         (a) Reflects replacement of equity gas (sold in Asset Sale) with
             purchased gas, i.e., the gas that was previously owned is now being
             purchased from the buyer.

         (b) Reflects loss of operating fees attributable to oil and gas
             properties sold in Asset Sale.

         (c) Reflects reduction in operating and general and administrative
             costs attributable to assets sold.

         (d) Reflects amortization of two years of prepaid gas transportation
             received as part of the purchase price.

         (e) Reflects loss of oil and gas sales from oil and gas properties
             sold.

     2.  Reflects reduction in depletion for oil and gas properties and in
         depreciation for pipeline as a result of the Asset Sale.

     3.  Reflects elimination of interest expense since a portion of the
         proceeds from the Asset Sale were used to liquidate the Company's bank
         debt.

     In accordance with the guidelines of the Securities and Exchange
Commission, interest or other income has not been imputed on the remaining cash
proceeds received by the Company in the Asset Sale nor have such cash proceeds
been assumed to have been spent for other purposes such as repurchasing shares
of the Company's stock or additional investments.
