                         NOTES TO FINANCIAL STATEMENTS
                                  (UNAUDITED)



(1)  GENERAL INFORMATION -

                  The financial statements included herein have been prepared
        by the Partnership and are unaudited except for the balance sheet at
        December 31, 1995 which has been taken from the audited financial
        statements at that date. The financial statements reflect adjustments,
        all of which were of a normal recurring nature, which are, in the
        opinion of the managing general partner necessary for a fair
        presentation. Certain information and footnote disclosures normally
        included in financial statements prepared in accordance with generally
        accepted accounting principles have been omitted pursuant to the rules
        and regulations of the Securities and Exchange Commission ("SEC"). The
        Partnership believes adequate disclosure is provided by the
        information presented. The financial statements should be read in
        conjunction with the audited financial statements and the notes
        included in the latest Form 10-K.

(2)  GAS IMBALANCES -

                  The gas imbalance receivable and deferred revenues are
        accounted for on the entitlements method, whereby the Partnership
        records its share of revenue, based on its entitled amount. Any
        amounts over or under the entitled amount are recorded as an increase
        or decrease to the gas imbalance receivable or deferred revenues as
        applicable.

(3)  VULNERABILITY DUE TO CERTAIN CONCENTRATIONS -

                  The Partnership's revenues are primarily the result of sales
        of its oil and natural gas production. Market prices of oil and
        natural gas may fluctuate and adversely affect operating results.

                  The Partnership extends credit to various companies in the
        oil and gas industry which results in a concentration of credit risk.
        This concentration of credit risk may be affected by changes in
        economic or other conditions and may accordingly impact the
        Partnership's overall credit risk. However, the Managing General
        Partner believes that the risk is mitigated by the size, reputation,
        and nature of the companies to which the Partnership extends credit.
        In addition, the Partnership generally does not require collateral or
        other security to support customer receivables.

(4)  FAIR VALUE OF FINANCIAL INSTRUMENTS -

                  The Partnership's financial instruments consist of cash and
        cash equivalents and short-term receivables and payables. The carrying
        amounts approximate fair value due to the highly liquid nature of the
        short-term instruments.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS


GENERAL

      The Partnership was formed for the purpose of investing in producing oil
and gas properties located within the continental United States. In order to
accomplish this, the Partnership goes through two distinct yet overlapping
phases with respect to its liquidity and results of operations. When the
Partnership is formed, it commences its "acquisition" phase, with all funds
placed in short-term investments until required for such property
acquisitions. The interest earned on these pre-acquisition investments becomes
the primary cash flow source for initial partner distributions. As the
Partnership acquires producing properties, net cash from operations becomes
available for distribution, along with the investment income. After
partnership funds have been expended on producing oil and gas properties, the
Partnership enters its "operations" phase. During this phase, oil and gas
sales generate substantially all revenues, and distributions to partners
reflect those revenues less all associated partnership expenses. The
Partnership may also derive proceeds from the sale of acquired oil and gas
properties, when the sale of such properties is economically appropriate or
preferable to continued operation.

LIQUIDITY AND CAPITAL RESOURCES

      The Partnership has completed acquisition of producing oil and gas
properties, expending all of limited partners' commitments available for
property acquisitions.

      The Partnership does not allow for additional assessments from the
partners to fund capital requirements. However, funds are available from
partnership revenues, borrowings or proceeds from the sale of partnership
property. The Managing General Partner believes that the funds currently
available to the Partnership will be adequate to meet any anticipated capital
requirements.

RESULTS OF OPERATIONS

      Oil and gas sales increased $114,664 or 58 percent in the first quarter
of 1996 when compared to the same period in 1995, partially due to increased
gas and oil prices. An increase in gas prices of 48 percent or $.64/MCF and in
oil prices of 11 percent or $1.85/BBL had a significant impact on partnership
performance. Current quarter gas and oil production declined 25 percent and 29
percent, respectively, when compared to first quarter 1995 production volumes,
partially offsetting the effect of increased gas and oil prices.

      Also, current quarter oil and gas sales increased due to the settlement
of pending litigation on the Kaiser Francis I acquisition, Cassel 1-17 well.
Take or pay proceeds were received in the amount of $119,150 and recorded in
the March revenues.

      Associated depreciation expense decreased 3 percent or $2,513.

      The Partnership recorded an additional provision in depreciation,
depletion and amortization in the first quarter of 1995 for $177,226 when the
present value, discounted at ten percent, of estimated future net revenues
from oil and gas properties, using the guidelines of the Securities and
Exchange Commission, was below the fair market value originally paid for oil
and gas properties. The additional provision results from the Managing General
Partner's determination that the fair market value paid for properties may or
may not coincide with reserve valuations determined according to guidelines of
the Securities and Exchange Commission.

      During 1996, partnership revenues and costs will be shared between the
limited partners and general partners in a 90:10 ratio.
