                            FOR THE FISCAL YEAR ENDED
                                DECEMBER 31, 1998

                                     PART I

ITEM 1.  BUSINESS

         Sterling Drilling Fund 1983-1, L.P., formerly Sterling-Fuel Resources
Drilling Fund 1983-1 (the "Registrant" or the "Partnership") is a limited
partnership formed under the laws of the State of New York on March 18, 1983.
The sole business of the Partnership was the drilling of formation extension
wells principally for natural gas in various locations in the State of West
Virginia. No exploratory drilling was undertaken.

         The principal place of business of the Partnership is at One Landmark
Square, Stamford, Connecticut 06901, telephone (203) 358-5700. The Managing
General Partner of the Partnership is PrimeEnergy Management Corporation, a New
York corporation which is a wholly-owned subsidiary of PrimeEnergy Corporation,
a publicly held Delaware corporation. Messrs. Charles E. Drimal, Jr., Oliver J.
Sterling and Samuel R. Campbell also are General Partners. Mr. Drimal is a
Director, President and Chief Executive Officer of PrimeEnergy Management
Corporation and PrimeEnergy Corporation, and Mr. Campbell is a Director of
PrimeEnergy Corporation.

         The aggregate contributions to the Partnership were $11,077,000, all of
which, net of the organization expenses of the Partnership, was expended in the
drilling of such formation extension wells. Such properties are located in Clay,
Roane, Calhoun, Gilmer, Wirt, Kanawha, Lincoln and Putnam Counties, West
Virginia. The Partnership does not operate any of the properties in which it has
an interest, but generally such properties are operated and serviced by Prime
Operating Company, a Texas corporation, and Eastern Oil Well Service Company, a
West Virginia corporation, both wholly-owned subsidiaries of PrimeEnergy
Corporation.

         During 1998, the Partnership did not engage in any development drilling
activities or the acquisition of any significant additional properties, but
engaged in the production of oil and gas from its producing properties in the
usual and customary course. Since January 1, 1999, and to the date of this
Report, the Partnership has not engaged in any drilling activities nor
participated in the acquisition of any material producing oil and gas
properties.

COMPETITION AND MARKETS

         Competitors of the Partnership in the marketing of its oil and gas
production include oil and gas companies, independent concerns, and individual
producers and operators, many of which have financial resources, staffs and
facilities substantially greater than those available to the Partnership.
Furthermore, domestic producers of oil and gas must not only compete with each
other in marketing their output, but must also compete with producers of
imported oil and gas and alternative energy sources such as coal, nuclear power
and hydroelectric power.


                                       -1-

<PAGE>   3




         The availability of a ready market for any oil and gas produced by the
Partnership at acceptable prices per unit of production will depend upon
numerous factors beyond the control of the Partnership, including the extent of
domestic production and importation of oil and gas, the proximity of the
Partnership's producing properties to gas pipelines and the availability and
capacity of such pipelines, the marketing of other competitive fuels,
fluctuation in demand, governmental regulation of production, refining,
transportation and sales, general national and worldwide economic conditions,
and pricing, use and allocation of oil and gas and their substitute fuels.

         The Partnership does not currently own or lease any bulk storage
facilities or pipelines, other than adjacent to and used in connection with
producing wells. The Partnership deals with a number of major and independent
companies for the purchase of its oil and gas production, in the areas of
production. In 1998, approximately $314,253, or 94.86%, of the Partnership's gas
production was sold to one unaffiliated purchaser, Phoenix Diversified and about
$12,820, or 100%, of oil production was purchased by the American Refining
Group. Neither purchaser has any relationship or is otherwise affiliated with
the Partnership. Sales are made under short-term contractual arrangements. The
Partnership believes that its current purchasers will continue to purchase oil
and gas products and, if not, could be replaced by other purchasers.

ENVIRONMENTAL MATTERS

         The petroleum industry is subject to numerous federal and state
environmental statutes, regulations and other pollution controls. In general,
the Partnership is, and will be subject to, present and future environmental
statutes and regulations, and in the future the cost of its activities may
materially increase as a result thereof. The Partnership's expenses relating to
preserving the environment during 1998 as they relate to its oil and gas
operations were not significant in relation to operating costs and the
Partnership expects no material change in the near future. The Partnership
believes that environmental regulations should not, in the future, result in a
curtailment of production or otherwise have a materially adverse effect on the
Partnership's operations or financial condition.

REGULATION

         The Partnership's oil and gas operations are subject to a wide variety
of federal, state and local regulations. Administrative agencies in such
jurisdictions may promulgate and enforce rules and regulations relating to,
among other things, drilling and spacing of oil and gas wells, production rates,
prevention of waste, conservation of natural gas and oil, pollution control, and
various other matters, all of which may affect the Partnership's future
operations and production of oil and gas. The Partnership's natural gas
production and prices received for natural gas are regulated by the Federal
Energy Regulatory Commission ("FERC") and the Natural Gas Policy Act of 1978 and
various state regulations. The Partnership was subject to the Crude Oil Windfall
Profit Tax Act of 1980, which imposed an excise tax on producers of crude oil at
various rates for prices received in excess of certain historical base prices.
That Act was repealed in August, 1988. The Partnership is also subject to state
drilling and proration regulations affecting its drilling operations and
production rates.

         The FERC continues to regulate interstate natural gas pipeline
transportation rates and service conditions pursuant to the NGA and NGPA.
Federal regulation of interstate transporters affects the marketing of natural
gas produced by the Partnership as well as the revenues received by the


                                       -2-

<PAGE>   4




Partnership for sales of such natural gas. Since the latter part of 1985,
through its Order Nos. 436, 500 and 636 rulemakings, the FERC has endeavored to
make natural gas transportation accessible to gas buyers and sellers on an open
and non-discriminatory basis. The FERC's efforts have significantly altered the
marketing and pricing of natural gas. No prediction can be made as to what
additional legislation may be proposed, if any, affecting the competitive status
of a gas producer, restricting the prices at which a producer may sell its gas,
or the market demand for gas, nor can it be predicted which proposals, including
those presently under consideration, if enacted, might be effective.

         A number of legislative proposals have been introduced in Congress and
the state legislatures of various states, that, if enacted, would significantly
affect the petroleum industry. Such proposals involve, among other things, the
imposition of land and use controls and certain measures designed to prevent
petroleum companies from acquiring assets in other energy areas. In addition,
there is always the possibility that if market conditions change dramatically in
favor of oil and gas producers that some new form of "windfall profit" or
severance tax may be proposed for and imposed upon either oil or gas. At the
present time it is impossible to predict which proposals, if any, will actually
be enacted by Congress or the various state legislatures. The Partnership
believes that it will comply with all orders and regulations applicable to its
operations. However, in view of the many uncertainties with respect to the
current controls, including their duration and possible modification together
with any new proposals that may be enacted, the Partnership cannot predict the
overall effect, if any, of such controls on its operations.

TAXATION

         The Partnership received an opinion of its counsel that the Partnership
would be classified as a partnership and the holders of Partnership Units would
be treated as limited partners for federal income tax purposes. The Partnership
itself, to the extent that it is treated for federal income tax purposes as a
partnership, is not subject to any federal income taxation, but it is required
to file annual partnership returns. Each holder of Partnership Units will be
allocated his distributive shares of the Partnership's income, gain, profit,
loss, deductions, credits, tax preference items and distributions for any
taxable year of the Partnership ending within or with his taxable year without
regard as to whether such holder has received or will receive any cash
distributions from the Partnership.

ITEM 2.  PROPERTIES

         The Partnership has no interest in any properties other than its oil
and gas properties. The information set forth below summarizes the Partnership's
oil and gas wells, production and reserves, for the periods indicated.

PRODUCING WELLS AND OPERATING INFORMATION

         The Partnership, following its formation, and in November, 1983,
contracted for the drilling of 38 development wells, which resulted in 37
producing wells and one dry hole.

         As of December 31, 1998, the Partnership had ownership interests in the
following gross and net producing oil and gas wells and gross and net producing
acres(1). The Partnership has no material undeveloped leasehold, mineral or
royalty acreage.

         (1)      A gross well is a well in which an interest is owned; a net
                  well is the sum of the interests owned in gross wells. Wells
                  are classified by their primary product. Some wells produce
                  both oil and gas.

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT

         The Managing General Partner of the Partnership is PrimeEnergy
Management Corporation, a New York corporation ("Management"). The principal
business of Management is the management of the Partnership and other publicly
and privately held exploration and development limited partnerships and joint

limited partnerships and joint ventures, of which 5 are publicly held, and is
the Managing Trustee of 2 Delaware Business Trusts. The primary activity of such
Partnerships, joint ventures and trusts is the production of oil and gas and
Management, as the Managing General Partner of the Partnership, will devote such

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Prime Operating Company acts as the operator for most of the producing
oil and gas wells of the Partnership pursuant to operating agreements with the
Partnership and other working interest owners, including other partnerships
managed by the Managing General Partner, and in 1998, was paid well operating
fees ranging from about $444 to $615 per month per well. Well operating supplies
and equipment and related servicing operations are generally provided by Eastern
Oil Well Service Company. The Partnership pays its proportionate part of such
operating fees and expenses. Such fees and expenses vary depending on such
matters as the location of the well, the complexity of the producing equipment,
whether wells produce oil or gas or both and similar factors. The Partnership
believes that such services are as favorable to the Partnership as they would be
if the Partnership entered into such transactions with unaffiliated third
parties. In 1998 and 1997, the Partnership paid an aggregate of $106,181 and
$116,779, respectively, in such fees and expenses.

ITEM 7.  MANAGEMENTS DISCUSSION & ANALYSIS OF FINANCIAL CONDITION & RESULTS OF 
         OPERATIONS

         1. Liquidity: The oil and gas industry is intensely competitive in all
its phases. There is also competition between this industry and other industries
in supplying energy and fuel requirements of industrial and residential
consumers. It is not possible for the Partnership to calculate its position in
the industry as the Partnership competes with many other companies having
substantially greater financial and other resources. In accordance with the
terms of the Agreement of Limited Partnership of the Partnership, the General
Partners of the Partnership will make cash distributions of as much of the
Partnership cash credited to the capital accounts of the partners as the General
Partners have determined is not necessary or desirable for the payment of any
contingent debts, liabilities or expenses for the conduct of the Partnership
business. As of December 31, 1998, the General Partners have distributed to the
Limited Partners $2,340,016 or 21.125% of the total Limited Partner capital
contributions to the Limited Partnership.

         The Year 2000 (Y2K) issue is the definition and resolution of potential
problems resulting from computer application programs or imbedded chip
instruction sets utilizing two-digits, as opposed to four digits, to define a
specific the year. Such date sensitive systems may be unable to properly
interpret dates, which could cause a system failure or other computer errors,
leading to disruptions in operations. The Partnership relies on the Managing
General Partner for all


                                       F-2

<PAGE>   15




management and administrative functions. Consequently, the Partnership's
exposure to the Y2K problems is determined by what Year 2000 efforts have been
undertaken by the Managing General Partner.

         In 1997, the Managing General Partner developed a three-phase program
for the Y2K information systems compliance. Phase I is to identify those systems
with which the Partnership has exposure to Y2K issues. Phase II is to remediate
systems and replace equipment where required. Phase III, to be completed by
mid-1999, is the final testing of each major area of exposure to ensure
compliance. The Managing General Partner has identified four major areas
determined to be critical for successful Y2K compliance: (1) financial and
informational system applications, (2) communications applications, (3) oil and
gas producing operations, and (4) third-party relationships.

         The Managing General Partner, in accordance with Phase I of the
program, is in the process of conducting an internal review of all systems and
contacting all software suppliers to determine major areas of exposure to Y2K
issues. The Managing General Partner has completed the modifications to its core
financial and reporting systems and is continuing to test compliance in this
area. These modifications were made in conjunction with an upgrade of the
financial reporting applications provided by the Managing General Partner's
software vendor. Conversion to the new system was completed during 1998. Due to
the technology advances in the communications area the Managing General Partner
has upgraded such equipment regularly over the past three years. Y2K compliance
was a specification requirement of each installation. Consequently, the Managing
General Partner expects exposure in this area to be limited to third party
readiness. The Managing General Partner is in the process of identifying areas
of exposure resulting from equipment used in its oil and gas producing
operations. The Managing General Partner expects to complete identification of
critical systems by June 1999 and to continue remediation and testing throughout
1999. In the third-party area, the Managing General Partner has received
assurance from its significant service suppliers that they intend to be Y2K
compliant by 2000. The Managing General Partner has implemented a program to
request Year 2000 certification or other assurance from other third parties
during 1999.

         The Partnership recognizes that, notwithstanding the efforts described
above, the Partnership could experience disruptions to its operations or
administrative functions, including those resulting from non-compliant systems
utilized by unrelated third party governmental and business entities. The
Managing General Partner is in the process of developing a contingency plan in
order to mitigate potential disruption to business operations. The Managing
General Partner expects to complete this contingency plan by the second quarter
of 1999 but also expects to refine this plan throughout 1999.

         Through 1998, the Managing General Partner has handled identifying,
remediating and testing systems for Year 2000 compliance within the scope of
routine upgrades and systems evaluations. The Managing General Partner expects
to complete the review of oil and gas operations exposure in the same manner,
without incurring substantial additional costs. However, information resulting
from the oil and gas operations review may indicate required expenditures not
currently contemplated by the Partnership.

         The net proved oil and gas reserves of the Partnership are considered
to be a primary indicator of financial strength and future liquidity. The
present value of unescalated future net revenue (S.E.C.


                                       F-3

<PAGE>   16




case) associated with such reserves, discounted at 10% as of December 31, 1998,
was approximately $915,800 as compared to the discounted reserves as of December
31, 1997, which were approximately $1,200,900.

         Reservoir engineering is a subjective process of estimating underground
accumulations of gas and oil that can not be measured in an exact manner. The
accuracy of any reserve estimate is a function of the quality of available data
and of the engineering and geological interpretation and judgment. Accordingly,
reserve estimates are generally different from the quantities of gas and oil
that are ultimately recovered and such differences may have a material impact on
the Partnership's financial results and future liquidity.

         2. Capital resources: The Partnership was formed for the sole intention
of drilling oil and gas wells. The Partnership entered into a drilling contract
with an independent drilling contractor in November, 1983, for $9,400,000.
Pursuant to the terms of this contract, thirty-eight wells were drilled
resulting in thirty-seven producing wells and one dry-hole.

         3.  Results of Operations:

         1998 compared to 1997

         Overall operating revenues declined from $379,079 in 1997 to $337,678
in 1998. The Partnership receives some of its revenue from oil production as
well as gas production. The Partnership's oil production did not change
significantly from 1997 to 1998, 1302 bbls to 1232 bbls respectively. The stable
production was offset by significantly lower average price per barrel, from
$19.64 in 1997 to $12.05 in 1998. The Partnership main source of revenue is from
its gas produced and sold. A decline in its gas production from 111,382 mcf in
1997 to 100,983 mcf in 1998 was only slightly offset by a very small increase in
average price per mcf from $3.15 in 1997 to $3.17 in 1998. Normal production
decline can sometimes be attributed to shut-ins and higher main transport line
pressures. The higher main line pressure can inhibit or restrict the free
movement of the Partnership's gas from the wells to the purchaser's transport
line.

         Interest income fluctuates with changes in the interest rates received
as well as the amount of cash in the bank at any given time.

         Production expenses decreased from $165,863 in 1997 to $152,083 in
1998. Some production expenses can be variable based upon to the volumes of gas
and oil produced. The operator also expends funds or repairs, labors,
maintenance and location costs based upon the needs at a particular well or well
site. During 1998, the majority of production expenses were associated with
routine maintenance at the wells or well sites. Any variable costs incurred were
reasonable based upon the current production volumes. During 1997, the operator
performed supplemental repairs which included location work, road repairs,
pipeline repairs and additional labor expenditures. In most cases large repairs
are made to help maintain overall production or to minimize current declines.
General and administrative costs remained relatively unchanged between 1997 and
1998, from $121,632 to $120,356, respectively. Management will use in-house
resources if it will provide efficient and timely services to the partnership.
Amounts in both years are substantially less than the $553,850 allocable to the
Partnership under the Partnership Agreement.

         The Partnership records additional depreciation, depletion and
amortization to the extent that the net capitalized costs exceed the
undiscounted future net cash flows attributable to the Partnership. No revisions
to the basis of the Partnership properties were needed in 1998 or 1997. The
overall depreciation for both years was consistent with the rates used and the
remaining property basis.

         1997 compared to 1996

         Operating revenue increased from $290,733 in 1996 to $379,079 in 1997.
This increase can be attributed to a variety of factors, including only minor
fluctuations in gas and oil production, from 113,227 mcf and 1,524 barrels in
1996 to 111,382 mcf and 1,302 barrels in 1997. Both gas and oil revenues were
helped substantially by the increased average price per mcf and barrel in 1997
when compared to 1996. On average, the Partnership was paid $2.31 per mcf and
$16.37 per barrel in 1996 and $3.15 per mcf and $19.64 per barrel in 1997. The
Partnership has locked into a favorable gas contract price that will be in place
until November of 1998.

         Production expenses increased from $135,780 in 1996 to $165,863 in
1997. The Partnership did expend funds on additional capitalized well equipment
and other repairs performed on a few wells. The operator will determine if
additional equipment, for example lift equipment, will have a beneficial effect
on production. The operator will also perform various repairs including but not
limited to location work, road repairs, pipeline repairs and additional labor
cost as deemed appropriate. In most cases large repairs are made to help
maintain overall production. Also the Partnership in both years expended the
necessary funds on the routine, general upkeep and maintenance of the well and
well site. General and administrative costs remained relatively unchanged
between 1996 and 1997, from $121,632 to $121,848, respectively. Management
continues to monitor any third party costs and use in-house resources if it will
provide efficient and timely services to the Partnership. Amounts in both years
are substantially less than the $553,850 allocable to the Partnership under the
Partnership Agreement.

         The Partnership records additional depreciation, depletion and

undiscounted future net cash flows attributable to the Partnership. No revisions

                          NOTES TO FINANCIAL STATEMENTS

                        DECEMBER 31, 1998, 1997 AND 1996




(1)      Organization and Capital Contributions:

         Sterling Drilling Fund 1983-1, L.P., formerly Sterling-Fuel Resources
         Drilling Fund 1983-1, a New York limited partnership (the
         "Partnership"), was formed on March 18, 1983 for the primary purpose of
         acquiring, developing and producing oil and gas in the state of West
         Virginia. The general partners are: PrimeEnergy Management Corporation
         (PEMC), a wholly owned subsidiary of PrimeEnergy Corporation (PEC),
         Charles E. Drimal, Jr., Oliver J. Sterling and Samuel R. Campbell.
         Eleven thousand seventy-seven limited partnership units, (11,077), were
         sold at $1,000 per unit aggregating total limited partner contributions
         of $11,077,000. The general partners' contributions amounted to
         $902,847. Partnership operations commenced on November 10, 1983.

(2)      Summary of Significant Accounting Policies:

         Revenue Recognition:

         The Partnership recognizes operating revenues, consisting of sales of
         oil and gas production, in the month of sale. Uncollected revenue is
         accrued based on known facts and trends of the relevant oil and gas
         properties on a monthly basis.

         Basis of Accounting:

         The accounts of the Partnership are maintained in accordance with
         accounting practices permitted for federal income tax reporting
         purposes. Under this method of accounting, (a) substantially all
         exploration and development costs except leasehold and equipment costs
         are expensed as paid, (b) costs of abandoned leases and equipment are
         expensed when abandoned, and (c) depreciation (for equipment placed in
         service) is provided on an accelerated basis. In order to present the
         accompanying financial statements in accordance with generally accepted
         accounting principles, memorandum adjustments have been made to account
         for oil and gas properties, as discussed below.

         Oil and Gas Producing Activities:

         The Partnership accounts for its oil and gas operations using the
         successful efforts method of accounting on a property by property
         basis. The Partnership only participates in developmental drilling.
         Accordingly, all costs of drilling and equipping these wells, together
         with leasehold acquisition costs, are capitalized. These capitalized
         costs are amortized on a property by property basis by the unit-of-

                        DECEMBER 31, 1998, 1997 AND 1996




(2)      Summary of Significant Accounting Policies - (Cont'd):

         production method based upon the ratio of production to proved oil and
         gas reserves. Additional depreciation, depletion and amortization may
         be recorded if net capitalized costs exceed the undiscounted future net
         cash flows attributable to Partnership properties. (See Note 4)

         Federal Income Taxes:

         As federal income taxes are the liability of the individual partners,
         the accompanying financial statements do not include any provision for
         federal income taxes. (See Note 8)

         Limited Partners' Loss Per Equity Unit:

         The limited partners' income (loss) per equity unit is computed on the
         11,077 limited partner equity units.

         Cash and Cash Equivalents:

         For purposes of the statements of cash flows the Partnership considers
         all highly liquid debt instruments with a maturity of three months or
         less to be cash equivalents.

         Use of Estimates:

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenues
         and expenses during the reporting period. Actual results could differ
         from those estimates.

(3)      Oil and Gas Properties:

         The Partnership acquired leases or farmouts from PEMC at its cost. Cost
         is defined as any amount paid for delay rentals, lease bonuses, if any,
         surveys and other expenses including such portion of any of the general
         partners', or their affiliates' reasonable, necessary and actual
         expenses for geological, geophysical, seismic, land, engineering,
         drafting, accounting, legal and other services. The Partnership
         currently pays royalties of approximately 12.5% to 17.9% of the selling
         price of the oil and gas extracted.

         The following table sets forth certain revenue and expense data
         concerning the Partnership's oil and gas activities for the years ended
         December 31, 1998, 1997 and 1996:

(4)      Quantities of Oil and Gas Reserves - (Cont'd):

         Should current prices continue into the future, operation of certain
         wells would become uneconomic, on a pretax basis, as production levels
         decline with age. In accordance with the rules and regulations of the
         Securities and Exchange Commission, proved reserves exclude production
         which would be uneconomic. The partners are entitled to certain tax
         benefits and credits which, if available in the future, may result in
         production continuing beyond the level included in the above table.

         Revisions arise from changes in current prices, as well as engineering
         and geological data which would alter the useful life and therefore the
         overall predicted production of each well. Future changes in these
         estimates are common and would impact the reserve quantities used to
         calculate depreciation, depletion and amortization.

         As discussed in Note 2, the Partnership may record additional
         depreciation, depletion and amortization if net capitalized costs
         exceed the undiscounted future net cash flows attributable to
         Partnership properties. Price declines affect estimated future net
         revenues both directly and as a consequence of their impact on
         estimates of future production. The Partnership has recorded no
         additional provision for 1998, 1997 or 1996. If the additional
         provision had been computed based on the limited partners' interest in
         capitalized costs and estimated future net revenues, rather than on the
         basis of total Partnership interests, the limited partners' income
         would not have been reduced for 1998, 1997 or 1996.

                percentage of working interest in the well. Such fee is subject
                to annual adjustment by the percentage increase in the Cost of
                Living Index published by the U.S. Department of Labor over the
                year in which production began. During 1998, 1997 and 1996,
                $104,801, $110,512, and $87,747 of production operator's fees
                were incurred, respectively.

         (c)    In accordance with the terms of the Partnership Agreement, the
                general partners are required to pay 8.5% of drilling and
                completion costs, lease acquisition costs and certain other
                costs, of which 1% will be paid for by the general partners out
                of revenues received by them from the Partnership. At December
                31, 1998, $21,720 was due from certain general partners for such
                costs.

         (d)    Eastern Oil Well Services Company (EOWSC), a subsidiary of PEC,
                provided field services to the Partnership during the years
                ending December 31, 1998 and 1997 for which it was billed $1,380
                and $6,267 respectively.


(7)      General and Administrative Expenses:

         In accordance with the Management Agreement, the general partners are
         reimbursed for the portion of their in-house overhead, including
         salaries and related benefits, attributable to the affairs and
         operations of the Partnership.

         This amount, combined with certain direct expenses for geology,
         engineering, legal, accounting, auditing, insurance and other items
         shall not exceed an annual amount equal to 5% of limited partner
         capital contributions. Excess expenses shall be borne by the general
         partners.

         During 1998, 1997 and 1996, the Partnership recognized general and
         administrative expenses incurred on its behalf by a general partner of
         $100,000, $100,000, and $100,000 respectively.

         The tax returns of the Partnership, the qualifications of the
         Partnership as such for tax purposes, and the amount of Partnership
         income or loss are subject to examination by federal and state taxing
         authorities. If such examinations result in changes with respect to
         Partnership's qualifications or in changes to its income or loss, the
         tax liability of the partners would be changed accordingly.

         The Tax Reform Act of 1976 provides that no part of any depletion
         deduction with respect to oil and gas wells is to be determined by the
         Partnership but must be computed separately by the partners. Thus, cost
         or percentage depletion, as applicable, must be computed by each
         partner so that a specific depletion computation can be made when each
         partner files his U.S. income tax return. Information is furnished to
         the partners to compute the depletion deduction.
