information:

ITEM 2.  Acquisition or Disposition of Assets

       On May 31, 2002 the Company consummated the sale of all of its domestic
oil and gas properties to Delta Petroleum Company ("Delta"). The sale was
pursuant to a definitive purchase and sale agreement dated January 15, 2002. At
closing the Company received $18,236,000 cash plus 9,566,000 shares of Delta
common stock. The $18,236,000 cash represents a $20,000,000 purchase price cash
component as of October 1, 2001, the effective date, less $1,764,000 of net cash
flow received by the Company applicable to production from the properties
subsequent to the effective date . It does not include approximately $3,300,000
of estimated net production revenue applicable to production subsequent to
October 1, 2001 that the Company had not received but will be received by Delta.
Pursuant to the governing purchase and sale agreement, the Company granted Delta
an option to repurchase up to 3,188,667 of Delta's shares at $4.50/share for a
period of one year after closing. The Delta stock received by the Company was
valued at $26,952,000 by an independent appraiser excluding the value of the
option granted to Delta to reacquire up to 3,188,667 of the Delta shares within
a year of closing. As a result of the sale, the Company will own approximately
44% of Delta.

                            EXPLANATION OF UNAUDITED
                   PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                               ("$000's" Omitted)


      On May 31, 2002 the Company consummated the sale of all of its domestic
oil and gas properties to Delta Petroleum Company ("Delta"). The sale was
pursuant to a definitive purchase and sale agreement dated January 15, 2002. At
closing the Company received $18,236 cash plus 9,566,000 shares of Delta common
stock. The $18,236 cash represents a $20,000 purchase price cash component as of
October 1, 2001, the effective date, less $1,764 of net cash flow received by
the Company applicable to production from the properties subsequent to the
effective date . It does not include approximately $3,300 of estimated net
production revenue applicable to production subsequent to October 1, 2001 that
the Company had not received but will be received by Delta. Pursuant to the
governing purchase and sale agreement, the Company granted Delta an option to
repurchase up to 3,188,667 of Delta's shares at $4.50/share for a period of one
year after closing. The Delta stock received by the Company was valued at
$26,952 by an independent broker excluding the value of the option granted to
Delta to reacquire up to 3,188,667 of the Delta shares within a year of closing.
As a result of the sale, the Company will own approximately 44% of Delta.

      The following unaudited pro forma consolidated balance sheet and
statements of operations of the Company reflect the pro forma effects of the
sale of the domestic oil and gas properties of Castle Energy Corporation to
Delta ("Sale") as if the Sale had occurred on (i) March 31, 2002 for balance
sheet purposes, (ii) October 1, 2000 for purposes of the statement of operations
for the year ended September 30, 2001 and (iii) October 1, 2000 for purposes of
the statement of operations for the six months ended March 31, 2002. The pro
forma adjustments to the aforementioned statements of operations include
adjustments to reflect the Company's share of Delta's earnings and losses. Such
adjustments, in turn, are based upon Delta's pro forma statements of operations
for Delta's fiscal year ended June 30, 2001 and for the six month period ended
December 31, 2001, which are included in Delta's Proxy Statement to its
shareholders dated May 2, 2002. Rules promulgated by the Securities and Exchange
Commission allow the Company to utilize or combine Delta's financial data with
that of the Company as long as Delta's fiscal periods do not differ from the
Company's fiscal periods by more than 93 days. The Company's fiscal year end is
September 30 while Delta's fiscal year end is June 30 hence the Company utilized
Delta's fiscal data for the periods ended June 30, 2001 and December 31, 2001
for the Company's pro forma statements of operations for the periods ended
September 30, 2001 and March 31, 2002. The Company's 44% equity interest in
Delta is accounted for under the equity method of accounting.

      The pro forma consolidated financial statements assume that Delta records
the 9,566,000 shares of its common stock issued to the Company at $37,977 as set
forth in Delta's pro forma financial statements included in its proxy to
shareholders. The Company, in turn, has computed its proportionate share of
Delta's equity at March 31, 2002 based upon Delta's aforementioned valuation of
the shares issued to the Company. The Company understands that Delta's valuation
of the shares was based upon preliminary estimates and may change in future
filings by Delta. Based upon Delta's valuation of the Delta shares issued to the
Company and the Company's appraisal of the Delta shares it received by an
independent appraiser, the Company estimates that its resulting investment in
Delta exceeds its proportional share of Delta's equity by approximately $1,454
at March 31, 2002. The Company currently believes that the excess should be
allocated to Delta's potential legal recovery from its offshore California oil
and gas leases but the Company is still awaiting additional information,
primarily evaluations of Delta's oil and gas properties, and Delta's final
determination of the valuation of its shares issued to the Company, in order to
finalize the allocation of such excess. Delta and eight other energy companies
which own interests in oil and gas leases off the California coast have sued the
United States Government for $1,200,000 for reimbursement damages for




                                    Page -3-




stalling their plans to develop these offshore oil and gas fields. The lawsuit
was filed January 9, 2002 in the U.S. Court of Federal Claims in Washington,
D.C. Delta's claim is for in excess of $152,000 plus exploration costs and
related expenses. The Company expects to finalize the allocation of its excess
investment in Delta within a year.

      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 purchase 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. Such assumption and estimates include but
are not limited to the estimates of cash flow earned from October 1, 2001 to
March 31, 2002, the excess of the Company's investment in Delta's stock over the
Company's proportional share of Delta's equity at March 31, 2002 and of other
items. The pro forma consolidated financial statements and accompanying notes
should be read in conjunction with the historical consolidated financial
statements of the Company and Delta and notes thereto and the other financial
information regarding the Company and Delta included in filings with the
Securities and Exchange Commission made by the Company and Delta.

a.  Reflects the operating results from the domestic oil and gas properties sold
    to Delta. Although the Company expects to reduce its corporate general and
    administrative expenses as a result of the Sale, no reduction of corporate
    general and administrative expenses has been reflected in the Pro Forma
    Consolidated Statement of Operations because the intended reductions have
    not yet been achieved. The Company has eliminated all exploration and
    production general and administrative expenses because Delta has assumed
    these operations, including hiring the related employees and assuming the
    related field office leases and other expenses.


b.  Reflects the Company's share of Delta's pro forma net income based upon the
    equity method of accounting as follows:


    Delta net income (loss) for fiscal year ended June 30, 2001         $   345

    The pro forma results do not reflect the gain of $1,608 directly related
    to the Sale

c.  Income tax benefits have been eliminated as a result of income tax valuation
    allowances for tax benefits otherwise arising from pro forma losses.


                                                                       VII (b) 4
