PART I

ITEM 1. BUSINESS.

General

PDC 1998-D Limited Partnership ("the Partnership") is a limited partnership formed on December 31, 1998 pursuant to the West Virginia Uniform Limited Partnership Act. Petroleum Development Corporation ("PDC") serves as Managing General Partner of the Partnership.

Since the commencement of operations on December 31, 1998, the Partnership has been engaged in onshore, domestic gas exploration exclusively in the northern Appalachian and Michigan Basins. A total of 11 limited partners contributed initial capital of $330,000; a total of 1,045 additional general partners contributed initial capital of $20,195,261; and PDC (Managing General Partner) contributed $4,464,244 in capital as a participant in accordance with contribution provisions of the Limited Partnership Agreement (the Agreement).

Under the terms of the Agreement, the allocation of revenues is as follows:



|                                        | Allocation of Revenues
|--------------------------------------- | ----------------------
|                                        |                       
|Additional General and Limited Partners | 80%                   
|                                        | ==                    
|Managing General Partner                | 20%                   
|                                        | ==                    

Operating and direct costs are allocated and charged to the additional general and limited partners and the Managing General Partner in the same percentages as revenues are allocated. Leasehold, drilling and completion costs, and equipment costs are borne 80% by the additional general and limited partners and 20% by the Managing General Partner.

Employees

The Partnership has no employees, however, PDC has approximately 90 employees which include a staff of geologists, petroleum engineers, landmen and accounting personnel who administer all of the Partnership's operations.

Plan of Operations

The Partnership participated in the drilling of 97 gross wells and will continue to operate and produce its 89 gross productive wells. The Partnership does not have unexpended initial capital and no additional drilling activity is planned.

See Item 2 herein for information concerning the Partnership's gas wells.

Markets for Oil and Gas

The availability of a market for any oil and gas produced from the operations of the Partnership will depend upon a number of factors beyond the control of the Partnership which cannot be accurately predicted. These factors include the proximity of the Partnership wells to and the capacity of natural gas pipelines, the availability and price of competitive fuels, fluctuations in seasonal supply and demand, and government regulation of supply and demand created by its pricing and allocation restrictions. Oversupplies of gas can be expected to occur from time to time and may result in the Partnership's wells being shut-in or curtailed. Increased imports of oil and natural gas have occurred and are expected to continue. The effects of such imports could adversely impact the market for domestic oil and natural gas.

2



Derivatives and Hedging Activities

The Managing General Partner utilizes commodity based derivative instruments as hedges to manage a portion of the Partnership's exposure to price volatility stemming from natural gas production. These instruments consist of natural gas futures and option contracts traded on the New York Mercantile Exchange. The futures and option contracts hedge committed and anticipated natural gas purchases, generally forecasted to occur within a 12 month period. The Managing General Partner does not hold or issue derivatives for trading or speculative purposes and permits utilization of hedges only if there is an underlying physical position.

The Managing General Partner has extensive experience with the use of financial hedges to reduce the risk and impact of natural gas price changes. These hedges are used to "lock in" fixed prices from time to time for the Managing General Partner and its various limited partnerships' share of production. In order for future contracts to serve as effective hedges, there must be sufficient correlation to the underlying hedged transaction. While hedging can help provide price protection if spot prices drop, hedges can also limited upside potential.

Despite the measure taken by the Managing General Partner to attempt to control price risk, the Partnership remains subject to price fluctuations for natural gas sold in the spot market. The Managing General Partner continues to evaluate the potential for reducing these risks by entering into hedge transactions. In addition, the Managing General Partner may also close out any portion of hedges that may exist from time to time.

Competition

The Partnership competes in marketing its gas with numerous companies and individuals, many of which have financial resources, staffs and facilities substantially greater than those of the Partnership or Petroleum Development Corporation.

State Regulations

State regulatory authorities have established rules and regulations requiring permits for well operations, reclamation bonds and reports concerning operations. States also have statutes and regulations concerning the spacing of wells, environmental matters and conservation, and have established regulations concerning the unitization and pooling of oil and gas properties and maximum rates of production from oil and gas wells. The Partnership believes it has complied in all material respects with applicable state regulations.

Federal Regulations

Regulation of Liquid Hydrocarbons. Liquid hydrocarbons (including crude oil and natural gas liquids) were subject to federal price and allocation controls until January 1981 when controls were effectively eliminated by executive order of the President. As a result, to the extent the Partnership sells oil produced from its properties, those sales are at unregulated market prices.

Although it appears unlikely under present circumstances that controls will be reimposed upon liquid hydrocarbons, it is possible Congress may enact such legislation at a future date. The impact of such legislation on the Partnership would be minimal since the partnership expects to sell only small quantities of liquid hydrocarbons, if any.

3

Natural Gas Regulation. Sale of natural gas by the Partnership is subject to regulation of production, transportation and pricing by governmental regulatory agencies. Generally, the regulatory agency in the state where a producing well is located regulates production activities and, in addition, the transportation of gas sold intrastate. The Federal Energy Regulatory Commission (FERC) regulates the operation and cost of interstate pipeline operators who transport gas. Currently the price of gas to be sold by the Partnership is not regulated by any state or federal agency.

Proposed Regulation. Numerous proposals concerning energy are being considered by the United States Congress, various state legislatures and regulatory agencies. The possible outcome and effect of these proposals cannot be accurately predicted.

Environmental and Safety Regulation. The Partnership believes that it complies, in all material respects, with all legislation and regulations affecting its operations in the drilling and production of oil and gas wells and the discharge of wastes. To date, compliance with such provisions and regulations has not had a material effect upon the Partnership's expenditures for capital equipment, its operations or its competitive position. The cost of such compliance is not anticipated to be material in the future.

ITEM 2. PROPERTIES.

Drilling Activity

The following table sets forth the results of drilling activity from December 31, 1998 (date of inception) to December 31, 2001, of the Partnership which was conducted in the Continental United States.



|                                 | Development Wells
|-------------------------------- | -----------------
|                                 | Gross            
|                                 | Productive       
|P Period Ended
December 31, 2001 | 89               
|                                 | ==               

The Partnership drilled three dry exploratory wells (2.69 net), two in Colorado and one in Michigan. No additional drilling activity is planned.

Summary of Productive Wells

The table below shows the number of the Partnership's gross and net wells by state as of December 31, 2001.



|              | Natural Gas Wells
|------------- | -----------------
|Location      | Gross            
|Michigan      | 37               
|Pennsylvania  | 42               
|West Virginia | 10               
|Total         | 89               
|              | ==               

A "productive well" is a well producing, or capable of producing, oil and gas in commercial quantities. For purposes of the above table, a "gross well" is one in which the Partnership has a working interest and a "net well" is a gross well multiplied by the Partnership's working interest to which it is entitled under its drilling agreement.

4

Title to Properties

The Partnership's interests in producing acreage are in the form of assigned direct interests in leases. Such properties are subject to customary royalty interests generally contracted for in connection with the acquisition of properties and could be subject to liens incident to operating agreements, liens for current taxes and other burdens. The Partnership believes that none of these burdens materially interfere with the use of such properties in the operation of the Partnership's business.

As is customary in the oil and gas industry, little or no investigation of title is made at the time of acquisition of undeveloped properties (other than a preliminary review of local mineral records). Investigations are generally made, including in most cases receiving a title opinion of legal counsel, before commencement of drilling operations. A thorough examination of title has been made with respect to all of the Partnership's producing properties and the Partnership believes that it has generally satisfactory title to such properties.

ITEM 3. LEGAL PROCEEDINGS.

The Managing General Partner as driller/operator is not party to any legal action that would materially affect the Managing General Partner's or Partnership's operations or financial statements.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

None.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND SECURITY HOLDER MATTERS.

At December 31, 2001, PDC 1998-D Limited Partnership had one Managing General Partner, 11 Limited Partners who fully paid for 16.5 units at $20,000 per unit of limited partnership interests and a total of 1,045 Additional General Partners who fully paid for 1,009.76305 units at $20,000 per unit of additional general partnership interests. No established public trading market exists for the interests.

Limited and additional general partnership interests are transferable, however no assignee of an interest in the Partnership can become a substituted partner without the written consent of the transferor and the Managing General Partner.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS.

Liquidity and Capital Resources

The Partnership was funded with initial Limited and Additional General Partner contributions of $20,525,261 and the Managing General Partner contributed $4,464,244 in accordance with the Agreement. Syndication and management fee costs of $2,668,284 were incurred leaving available cash of $22,321,221 for Partnership activities.

The Partnership began exploration and development activities subsequent to the funding of the Partnership and completed these activities by December 31, 1999. Ninety-seven wells have been drilled, eighty-nine of which have been completed as producers. No additional wells will be drilled.

The Partnership had working capital at December 31, 2001 of $335,298.

Operations are expected to be conducted with available funds and revenues generated from oil and gas activities. No bank borrowings are anticipated.

Results of Operations

2001 Compared to 2000

Oil and gas sales increased 15% in 2001 compared to 2000 due to higher average sales prices of natural gas offset by decreased sales volumes. Cash distributions increased from $1,315,827 in 2000 to $1,835,797 in 2001.

2000 Compared to 1999

Oil and gas sales increased 87% in 2000 compared to 1999 due to increased sales volumes (1999 was not a full production year.) Cash distributions increased from $470,207 in 1999 to $1,315,827 due to increase in sales and also due to 1999 not being a full production year. Oil and gas sales commenced during the second quarter of 1999 with revenue distributions to the partners commencing in the third quarter. The net loss in 1999 of $12,503,892 was primarily due to the impairment charge for oil and gas properties which amounted to $10,764,226 in 1999. This impairment resulted from net capitalized costs exceeding estimated undiscounted future net cash flows. The impairment was based on estimated fair value which considered future discounted cash flows.

The Partnership's revenues from natural gas sales will be affected by changes in prices. Natural gas prices are subject to general market conditions which drive the pricing changes.

The principal effects of inflation upon the Partnership relate to the costs required to drill, complete and operate oil and gas wells. The Partnership expects these costs to remain somewhat stable over the next year.

Critical Accounting Policies



Certain accounting policies are very important to the portrayal of the Partnership's financial condition and results of operations and require management's most subjective or complex judgments. The policies are as follows:











6





Impairment of Long-Lived Assets

The Partnership assesses impairment of capitalized costs of proved oil and gas properties by comparing net capitalized costs to undiscounted future net cash flows on a field-by-field basis using expected prices. Prices utilized in each year's calculation for measurement purposes and expected costs are held constant throughout the estimated life of the properties. If net capitalized costs exceed undiscounted future net cash flow, the measurement of impairment is based on estimated fair value which would consider future discounted cash flows.

The judgments used in applying the above policies are based on management's evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from those estimates. See additional discussions in this Management's Discussion and Analysis.

New Accounting Standards

Statement of Financial Accounting Standards No. 141, "Business Combinations" ("SFAS No. 141") and Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142") were issued in July 2001. SFAS No. 141 requires that all business combinations entered into subsequent to June 30, 2001 be accounted for under the purchase method of accounting and establishes specific criteria for the recognition of intangible assets separately from goodwill. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS 142. SFAS 142 also requires that intangible assets with definite useful lives be amortized over their respective estimated useful lives to their estimated residual value, and subsequently reviewed for impairment. The Partnership does not believe that the adoption of these statements will have a material effect on its financial position, results of operations, or cash flows.

In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement Obligations" ("SFAS No. 143"). SFAS No. 143 requires the Partnership to record the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. The Partnership also records a corresponding asset which is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation will be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The Partnership is required to adopt SFAS No. 143 on January 1, 2003. At this time, the Partnership cannot reasonably estimate the effect of the adoption of this Statement on either its financial position, results of operations, or cash flows.

In August, 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144"). SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its







7





estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. SFAS No. 144 requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. The Partnership is required to adopt SFAS No. 144 on January 1, 2002. The Partnership does not believe that the adoption of this statement will have a material effect on its financial position, results of operations or cash flows.



Item 7.a.  Quantitative and Qualitative Disclosure About Market Risk.

Market-Sensitive Instruments and Risk Management

The Partnership's primary market risk exposure is commodity price risk. This exposure is discussed in detail below:

Commodity Price Risk

The Managing General Partner of the Partnership utilizes commodity-based derivative instruments as hedges to manage a portion of the Partnership's exposure to price risk from its natural gas sales. These instruments consist of NYMEX-traded natural gas futures contracts and option contracts. These hedging arrangements have the effect of locking in for specified periods (at predetermined prices or ranges of prices) the prices the Partnership will receive for the volume to which the hedge relates. As a result, while these hedging arrangements are structured to reduce the Partnership's exposure to decreases in price associated with the hedging commodity, they also limit the benefit the Partnership might otherwise have received from price increases associated with the hedged commodity. The Partnership's policy prohibits the use of natural gas future and option contracts for speculative purposes. As of December 31, 2001, the Partnership had no future contracts or options. As of December 31, 2000, the Partnership had entered into a series of natural gas future contracts and option contracts. Open future contracts maturing in 2001 were for the sale of 376,330 dt of natural gas with a weighted average price of $2.98 dt resulting in a total contract amount of $1,121,650, and a fair market value of $(1,451,573). Open option contracts maturing in 2001 were for the sale of 501,773 dt with a weighted average floor price of $3.68 dt and a fair value of $(166,965).

Disclosure of Limitations

As the information above incorporates only those exposures that exist at December 31, 2001, it does not consider those exposures or positions which could arise after that date. As a result, the Partnership's ultimate realized gain or loss with respect to commodity price fluctuations will depend on the exposures that arise during the period, the Partnership's hedging strategies at the time and commodity prices at the time.

PDC 1998-D LIMITED PARTNERSHIP

(A West Virginia Limited Partnership)

Notes to Financial Statements

Years Ended December 31, 2001, 2000 and 1999

(1)  Summary of Significant Accounting Policies

Partnership Financial Statement Presentation Basis

The financial statements include only those assets, liabilities and results of operations of the partners which relate to the business of PDC 1998-D Limited Partnership (the Partnership). The statements do not include any assets, liabilities, revenues or expenses attributable to any of the partners' other activities.

Oil and Gas Properties

The Partnership follows the successful efforts method of accounting for the cost of exploring for and developing oil and gas reserves. Under this method, costs of development wells, including equipment and intangible drilling costs related to both producing wells and developmental dry holes, and successful exploratory wells are capitalized and amortized on an annual basis to operations by the units-of-production method using estimated proved developed reserves determined at year end by the Managing General Partner's petroleum engineers at December 31, 2001, and by an independent petroleum engineer, Wright & Company, Inc. at December 31, 2000 and 1999. If a determination is made that an exploratory well has not discovered economically producible reserves, then its costs are expensed as dry hole costs.

The Partnership assesses impairment of capitalized costs of proved oil and gas properties by comparing net capitalized costs to undiscounted future net cash flows on a field-by-field basis using expected prices. Prices utilized in each year's calculation for measurement purposes and expected costs are held constant throughout the estimated life of the properties. If net capitalized costs exceed undiscounted future net cash flow, the measurement of impairment is based on estimated fair value which would consider future discounted cash flows. During 1999 the loss on impairment of oil and gas properties as reflected in the Statement of Operations amounted to $10,764,226.

Based on the Managing General Partner's experience, management believes site restoration, dismantlement and abandonment costs, net of salvage to be immaterial in relation to operating costs. These costs are being expensed when incurred.

Income Taxes

Since the taxable income or loss of the Partnership is reported in the separate tax returns of the partners, no provision has been made for income taxes on the Partnership's books.

Under federal income tax laws, regulations and administrative rulings, certain types of transactions may be accorded varying interpretations. Accordingly, the Partnership's tax return and, consequently, individual tax returns of the partners may be changed to conform to the tax treatment resulting from a review by the Internal Revenue Service.

Derivatives Financial Instruments

The Managing General Partner utilizes commodity based derivative instruments as hedges to manage a portion of the Partnership's exposure to price volatility stemming from natural gas production. These instruments consist of natural gas futures and option contracts traded on the New York Mercantile Exchange. The futures and option contracts hedge committed and anticipated natural gas sales generally forecasted to occur within a 12 month period. The Managing General Partner does not hold or issue derivatives for trading or speculative purposes.

As of December 31, 2001, the Partnership had no future contracts or options contracts for the sale of natural gas.

All derivatives are recognized on the Partnership's balance sheet at their fair value. On the date the derivative contract is entered into, the Managing General Partner designates the derivative as either a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow" hedge), or a non-hedging derivative. The Managing General Partner formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash-flow hedges to specific firm commitments or forecasted transactions. The Managing General Partner also formally assesses, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Partnership discontinues hedge accounting prospectively. No hedging activities were discontinued during 2001.

Changes in fair value of a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge are recorded in accumulated other comprehensive income, until earnings are affected by the variability in cash flows of the designated hedged item. Changes in the fair value of non-hedging derivatives are reported in current-period earnings. The Partnership discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised. Additionally, if the derivative is dedesignated as a hedging instrument, because it is unlikely that a forecasted transaction will occur, a hedged firm commitment no longer meets the definition of a firm commitment, or management determines that designation of the derivative as a hedging instrument is no longer appropriate, hedge accounting will discontinue.

For the years ended December 31, 2000 and 1999, prior to adoption of Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Certain Hedging Activities" and SFAS No. 138, "Accounting for Certain Hedging Activities", gains and losses related to qualifying hedges of firm commitments or anticipated transactions through the use of natural gas futures and option contracts were deferred and recognized in income or as adjustments of carrying amounts when the underlying hedged transaction occurred. In order for futures contracts to qualify as a hedge, there must have been sufficient correlation to the underlying hedged transaction.

Notes to Financial Statements, Continued

The Partnership adopted the provisions of SFAS 133/138 effective January 1, 2001. The natural gas futures and options are derivatives pursuant to SFAS 133/138. The Partnership's derivatives are treated as hedges of committed and/or anticipated transactions. On adoption of this Statement on January 1, 2001, the Partnership recorded a net transition adjustment of ($1,618,538) which was recorded in accumulated other comprehensive income (AOCI). During the year ended December 31, 2001, the Partnership reclassified $797,496, from AOCI into oil and gas sales relating to settled contracts.

As of December 31, 2000 the Partnership had futures contracts for the sale of 376,330 dt of natural gas and option contracts for the sale of 501,773 dt of natural gas. While these contracts have nominal carrying value, their fair value, represented by the estimated amount that would be received (paid) upon termination of the contracts, based on market quotes, was a fair value of ($1,618,538).



By using derivative financial instruments to hedge exposures to changes in commodity prices, the Managing General Partner exposes the Partnership to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Partnerhip, which creates repayment risk. The Managing General Partner minimizes the credit or repayment risk in derivative instruments by entering into transactions with high-quality counterparties.

Use of Estimates

The Partnership has made a number of estimates and assumptions relating to the reporting of assets and liabilities and revenues and expenses and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with generally accepted accounting principles. Actual results could differ from those estimates. Estimates which are particularly significant to the financial statements include estimates of oil and gas reserves and future cash flows from oil and gas properties which are used in assessing impairment of long-lived assets.

New Accounting Standards

Statement of Financial Accounting Standards No. 141, "Business Combinations" ("SFAS No. 141") and Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" ("SFAS No. 142") were issued in July 2001. SFAS No. 141 requires that all business combinations entered into subsequent to June 30, 2001 be accounted for under the purchase method of accounting and establishes specific criteria for the recognition of intangible assets separately from goodwill. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS 142. SFAS 142 also requires that intangible assets with definite useful lives be amortized over their respective estimated useful lives to their estimated residual value, and subsequently reviewed for impairment. The Partnership does not believe that the adoption of these statements will have a material effect on its financial position, results of operations, or cash flows.

Notes to Financial Statements, Continued

In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement Obligations" ("SFAS No. 143"). SFAS No. 143 requires the Partnership to record the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. The Partnership also records a corresponding asset which is depreciated over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation will be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The Partnership is required to adopt SFAS No. 143 on January 1, 2003. At this time, the Partnership cannot reasonably estimate the effect of the adoption of this Statement on either its financial position, results of operations, or cash flows.

In August, 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144"). SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. SFAS No. 144 requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. The Partnership is required to adopt SFAS No. 144 on January 1, 2002. The Partnership does not believe that the adoption of this statement will have a material effect on its financial position, results of operations or cash flows.

(2)  Organization

The Partnership was organized as a limited partnership on December 31, 1998 in accordance with the laws of the State of West Virginia for the purpose of engaging in the drilling, completion and operation of oil and gas development and exploratory wells in the Northern Appalachian, Michigan and Colorado Basins.

Purchasers of partnership units subscribed to and fully paid for 16.5 units of limited partner interests and 1,009.76305 units of additional general partner interests at $20,000 per unit (Investor Partners). Petroleum Development Corporation has been designated the Managing General Partner of the Partnership. Although costs, revenues and cash distributions allocable to the limited and additional general partners are shared pro rata based upon the amount of their subscriptions, including the Managing General Partner to the extent of its capital contributions, there are significant differences in the federal income tax effects and liability associated with these different types of units in the Partnership.

Notes to Financial Statements, Continued

Upon completion of the drilling phase of the Partnership's wells, all additional general partners units are converted into units of limited partner interests and thereafter become limited partners of the Partnership. Limited partners do not have any rights to convert their units into units of additional general partner interests in the Partnership.

In accordance with the terms of the Partnership Agreement (the Agreement), the Managing General Partner manages all activities of the Partnership and acts as the intermediary for substantially all Partnership transactions.

(3)  Transactions with Managing General Partner and Affiliates

The Partnership's transactions with the Managing General Partner include the following:

(3)     The Managing General Partner receives monthly reimbursement from the Partnership for their direct costs incurred by the Managing General Partner on behalf of the Partnership.

(4)     The revenues and expenses allocated to the partners are subject to a special provision in the partnership agreement, whereby the allocable share of revenues and expenses of the Investor Partners may be increased and the interest of the Managing General Partner may be decreased if certain cash distribution levels are not met. The shifting of the allocable share of revenues and expenses to the Investor Partners in the event that certain prescribed cash distribution levels are not attained may also serve to shift an increased amount of cash distributions to the Investor Partners and a decreased amount of cash distributions to the Managing General Partner.

(5)     In the event of the sale or other disposition of a productive well, a lease upon which such well is situated, or any equipment related to any such lease or well, the proceeds from such sale or disposition shall be allocated and credited to the Partners as oil and gas revenues are allocated. The term "proceeds" above does not include revenues from a royalty, overriding royalty, lease interest reserved, or other promotional consideration received by the Partnership in connection with any sale or disposition, which revenues shall be allocated to the Investor Partners and the Managing General Partner in the same percentages that oil and gas revenues are allocated. No such sales have occurred.

(6)     In accordance with the repurchase provision of the partnership prospectus, PDC may repurchase units from the investing partners which is entirely voluntary on the part of the partners. During 2001 PDC purchased a total of .25 units of partnership interest for a total ownership of 11.75 units as of December 31, 2001 which represents a 1.14% ownership of the Investor Partners share of limited and additional general partnership units. Therefore, costs and revenues and distributions for these purchased units are allocated to PDC in accordance with the Investor Partners allocation percentages disclosed in this table.

(6)  Income Taxes

As a result of the differences in the treatment of certain items for income tax purposes as opposed to financial reporting purposes, primarily depreciation, depletion and amortization of oil and gas properties and the recognition of intangible drilling costs as an expense or capital item, the income tax basis of oil and gas properties differs from the basis used for financial reporting purposes. At December 31, 2001, 2000 and 1999, the income tax basis of the partnership's oil and gas properties was $2,272,083, $3,000,920 and $3,831,866, respectively.
