(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, 1994 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) DEFERRED REVENUES -

          Deferred Revenues represent a gas imbalance liability assumed
    as part of property acquisitions. The imbalance is 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 deferred
    revenues.

(3) CONCENTRATION OF CREDIT RISK -

          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.

              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 result 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 the limited partners' commitments available for
property acquisitions.

     The Partnership does not allow for additional assessments from the
partners to fund capital requirements. However, funds in addition to the
remaining unexpended net capital commitments of the partners 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

     The following analysis explains changes in the revenue and expense
categories for the quarter ended September 30, 1995 (current quarter) when
compared to the quarter ended September 30, 1994 (corresponding quarter), and
for the nine months ended September 30, 1995 (current period), when compared
to the nine months ended September 30, 1994 (corresponding period).

THREE MONTHS ENDED SEPTEMBER 30, 1995 AND 1994

     Oil and gas sales declined $155,976 or 54 percent in the current quarter
of 1995 when compared to the corresponding quarter in 1994, primarily due to
decreased gas and oil production. Current quarter gas and oil production
declined 51 percent and 38 percent, respectively, when compared to third
quarter 1994 production volumes. A decline in gas and oil prices of 14
percent or $.25/MCF and 18 percent or $3.05/BBL, respectively, further
contributed to decreased revenues.

      Associated depreciation expense decreased 54 percent or $51,828.

     The Partnership recorded an additional provision in depreciation,
depletion and amortization in the third quarter of 1995 for $76,437 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. Using
prices in effect at September 30, 1994, the Partnership would have recorded
an additional provision at September 30, 1994 in the amount of $448,517.
However, these temporarily low quarter-end prices rebounded and by using
prices in effect at the filing date, the Partnership's unamortized cost of
oil and gas properties were not limited by this calculation.

               CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

NINE MONTHS ENDED SEPTEMBER 30, 1995 AND 1994

     Oil and gas sales decreased $299,312 or 34 percent in the first nine
months of 1995 over the corresponding period in 1994. A decline of 24 percent
in gas production and 24 percent in oil production were significant factors
in the decreased revenues for the period. Also, current period gas prices
decreased 25 percent or $.48/MCF compared to the corresponding period in
1994, further contributing to decreased income.

      Associated depreciation expense decreased 28 percent or $82,187.

     The Partnership recorded an additional provision in depreciation,
depletion and amortization in the first nine months of 1995 for $640,903 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 Exchange Commission.

     During 1995, partnership revenues and costs will be shared between the
limited partners and general partners in a 90:10 ratio.
