ACCOUNTING POLICIES ------------------- The combined balance sheets as of September 30, 2005, combined statements of operations for the three and nine months ended September 30, 2005 and 2004, and combined statements of cash flows for the nine months ended September 30, 2005 and 2004 have been prepared by Geodyne Resources, Inc., the General Partner of the limited partnerships, without audit. Each limited partnership is a general partner in the related Geodyne Energy Income Production Partnership in which Geodyne Resources, Inc. serves as the managing partner. Unless the context indicates otherwise, all references to a "Partnership" or the "Partnerships" are references to the limited partnership and its related production partnership, collectively, and all references to the "General Partner" are references to the general partner of the limited partnerships and the managing partner of the production partnerships, collectively. In the opinion of management the financial statements referred to above include all necessary adjustments, consisting of normal recurring adjustments, to present fairly the combined financial position at September 30, 2005, the combined results of operations for the three and nine months ended September 30, 2005 and 2004, and the combined cash flows for the nine months ended September 30, 2005 and 2004. Information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. The accompanying interim financial statements should be read in conjunction with the Partnerships' Annual Report on Form 10-K filed for the year ended December 31, 2004. The results of operations for the period ended September 30, 2005 are not necessarily indicative of the results to be expected for the full year. The Limited Partners' net income or loss per unit is based upon each $1,000 initial capital contribution. -14- OIL AND GAS PROPERTIES ---------------------- The Partnerships follow the successful efforts method of accounting for their oil and gas properties. Under the successful efforts method, the Partnerships capitalize all property acquisition costs and development costs incurred in connection with the further development of oil and gas reserves. Property acquisition costs include costs incurred by the Partnerships or the General Partner to acquire producing properties, including related title insurance or examination costs, commissions, engineering, legal and accounting fees, and similar costs directly related to the acquisitions, plus an allocated portion, of the General Partner's property screening costs. The acquisition cost to the Partnerships of properties acquired by the General Partner is adjusted to reflect the net cash results of operations, including interest incurred to finance the acquisition, for the period of time the properties are held by the General Partner. Depletion of the costs of producing oil and gas properties, amortization of related intangible drilling and development costs, and depreciation of tangible lease and well equipment are computed on the unit-of-production method. The Partnerships' depletion, depreciation, and amortization includes estimated dismantlement and abandonment costs and estimated salvage value of the equipment. When complete units of depreciable property are retired or sold, the asset cost and related accumulated depreciation are eliminated with any gain or loss (including the elimination of the asset retirement obligation) reflected in income. When less than complete units of depreciable property are retired or sold, the proceeds are credited to oil and gas properties. ACCRUED LIABILITY - OTHER ------------------------- The Accrued Liability - Other at December 31, 2004 for the I-E and I-F Partnerships represents a charge accrued for the payment of a judgment related to plugging liabilities. The decrease in Accrued Liability - Other from December 31, 2004 to September 30, 2005 was due to a ruling made by the Texas Supreme Court on April 8, 2005 that the Partnerships did not owe this liability. -15- ASSET RETIREMENT OBLIGATIONS ---------------------------- The Partnerships' wells must be properly plugged and abandoned after their oil and gas reserves are exhausted. The Partnerships follow FAS No. 143, "Accounting for Asset Retirement Obligations" in accounting for the future expenditures that will be necessary to plug and abandon these wells. FAS No. 143 requires the estimated plugging and abandonment obligations to be recognized in the period in which they are incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of fair value can be made and to be capitalized as part of the carrying amount of the well. Estimated abandonment dates will be revised in the future based on changes to related economic lives, which vary with product prices and production costs. Estimated plugging costs may also be adjusted to reflect changing industry experience. The Partnerships' asset retirement obligations were revised upward for the three months ended September 30, 2005 due to an increase in both the labor and rig costs associated with plugging wells. Cash flows would not be affected until wells are actually plugged and abandoned. The asset retirement obligation will be adjusted upwards each quarter in order to recognize accretion of the time-related discount factor. For the nine months ended September 30, 2005, the I-D, I-E, and I-F Partnerships recognized approximately $10,000, $109,000, and $54,000, respectively, of an increase in depreciation, depletion, and amortization expense, which was comprised of accretion of the asset retirement obligation and depletion of the increase in capitalized cost of oil and gas properties. The components of the change in asset retirement obligations for the three and nine months ended September 30, 2005 and 2004 are as shown below.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES - ----------------------------------------------- This Quarterly Report contains certain forward-looking statements. The words "anticipate", "believe", "expect", "plan", "intend", "estimate", "project", "could", "may" and similar expressions are intended to identify forward-looking statements. Such statements reflect management's current views with respect to future events and financial performance. This Quarterly Report also includes certain information, which is, or is based upon, estimates and assumptions. Such estimates and assumptions are management's efforts to accurately reflect the condition and operation of the Partnerships. Use of forward-looking statements and estimates and assumptions involve risks and uncertainties which include, but are not limited to, the volatility of oil and gas prices, the uncertainty of reserve information, the operating risk associated with oil and gas properties (including the risk of personal injury, death, property damage, damage to the well or producing reservoir, environmental contamination, and other operating risks), the prospect of changing tax and regulatory laws, the availability and capacity of processing and transportation facilities, the general economic climate, the supply and price of foreign imports of oil and gas, the level of consumer product demand, and the price and availability of alternative fuels. Should one or more of these risks or uncertainties occur or should estimates or underlying assumptions prove incorrect, actual conditions or results may vary materially and adversely from those stated, anticipated, believed, estimated, and otherwise indicated. GENERAL - ------- The Partnerships are engaged in the business of acquiring and operating producing oil and gas properties located in the continental United States. In general, a Partnership acquired producing properties and did not engage in development drilling or enhanced recovery projects, except as an incidental part of the management of the producing properties acquired. Therefore, the economic life of each Partnership, and its related Production Partnership, is limited to the period of time required to fully produce its acquired oil and gas reserves. The net proceeds from the oil and gas operations are distributed to the Limited Partners and the General Partner in accordance with the terms of the Partnerships' partnership agreements. -20- LIQUIDITY AND CAPITAL RESOURCES - ------------------------------- The Partnerships began operations and investors were assigned their rights as Limited Partners, having made capital contributions in the amounts and on the dates set forth below: Limited Date of Partner Capital Partnership Activation Contributions ----------- ------------------ --------------- I-D March 4, 1986 $ 7,194,700 I-E September 10, 1986 41,839,400 I-F December 16, 1986 14,320,900 In general, the amount of funds available for acquisition of producing properties was equal to the capital contributions of the Limited Partners, less 15% for sales commissions and organization and management fees. All of the Partnerships have fully invested their capital contributions. Net proceeds from the operations less necessary operating capital are distributed to the Limited Partners on a quarterly basis. Revenues and net proceeds of a Partnership are largely dependent upon the volumes of oil and gas sold and the prices received for such oil and gas. While the General Partner cannot predict future pricing trends, it believes the working capital available as of September 30, 2005 and the net revenue generated from future operations will provide sufficient working capital to meet current and future obligations. Occasional expenditures for new wells or well recompletions or workovers, however, may reduce or eliminate cash available for a particular quarterly cash distribution. Pursuant to the terms of the Partnerships' partnership agreements (the "Partnership Agreements"), the Partnerships would have terminated on December 31, 1999. However, the Partnership Agreements provide that the General Partner may extend the term of each Partnership for up to five periods of two years each. As of the date of this Quarterly Report, the General Partner has extended the terms of the Partnerships for their fourth two year extension period to December 31, 2007. -21- CRITICAL ACCOUNTING POLICIES - ---------------------------- The Partnerships follow the successful efforts method of accounting for their oil and gas properties. Under the successful efforts method, the Partnerships capitalize all property acquisition costs and development costs incurred in connection with the further development of oil and gas reserves. Property acquisition costs include costs incurred by the Partnerships or the General Partner to acquire producing properties, including related title insurance or examination costs, commissions, engineering, legal and accounting fees, and similar costs directly related to the acquisitions plus an allocated portion of the General Partner's property screening costs. The acquisition cost to the Partnerships of the properties acquired by the General Partner is adjusted to reflect the net cash results of operations, including interest incurred to finance the acquisition, for the period of time the properties are held by the General Partner. Depletion of the cost of producing oil and gas properties, amortization of related intangible drilling and development costs, and depreciation of tangible lease and well equipment are computed on the unit-of-production method. The Partnerships' calculation of depreciation, depletion, and amortization includes estimated dismantlement and abandonment costs and estimated salvage value of the equipment. When complete units of depreciable property are retired or sold, the asset cost and related accumulated depreciation are eliminated with any gain or loss (including the elimination of the asset retirement obligation) reflected in income. When less than complete units of depreciable property are retired or sold, the proceeds are credited to oil and gas properties. The Partnerships evaluate the recoverability of the carrying costs of their proved oil and gas properties for each oil and gas field (rather than separately for each well). If the unamortized costs of oil and gas properties within a field exceeds the expected undiscounted future cash flows from such properties, the cost of the properties is written down to fair value, which is determined by using the estimated discounted future cash flows from the properties. The risk that the Partnerships will be required to record impairment provisions in the future increases as oil and gas prices decrease. The Deferred Charge on the Balance Sheets represents costs deferred for lease operating expenses incurred in connection with the Partnerships' underproduced gas imbalance positions. Conversely, the Accrued Liability represents charges accrued for lease operating expenses incurred in connection with the Partnerships' overproduced gas imbalance positions. The rate used in calculating the Deferred Charge and Accrued Liability is the annual average production costs per Mcf. -22- The Partnerships' oil and condensate production is sold, title passed, and revenue recognized at or near the Partnerships' wells under short-term purchase contracts at prevailing prices in accordance with arrangements which are customary in the oil and gas industry. Sales of gas applicable to the Partnerships' interest in producing oil and gas leases are recorded as revenue when the gas is metered and title transferred pursuant to the gas sales contracts covering the Partnerships' interest in gas reserves. During such times as a Partnership's sales of gas exceed its pro rata ownership in a well, such sales are recorded as revenues unless total sales from the well have exceeded the Partnership's share of estimated total gas reserves underlying the property, at which time such excess is recorded as a liability. The rates per Mcf used to calculate this liability are based on the average gas price for which the Partnerships are currently settling this liability. These amounts were recorded as gas imbalance payables in accordance with the sales method. These gas imbalance payables will be settled by either gas production by the underproduced party in excess of current estimates of total gas reserves for the well or by negotiated or contractual payment to the underproduced party. ASSET RETIREMENT OBLIGATIONS - ---------------------------- The Partnerships' wells must be properly plugged and abandoned after their oil and gas reserves are exhausted. The Partnerships follow FAS No. 143, "Accounting for Asset Retirement Obligations" in accounting for the future expenditures that will be necessary to plug and abandon these wells. FAS No. 143 requires the estimated plugging and abandonment obligations to be recognized in the period in which they are incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of fair value can be made and to be capitalized as part of the carrying amount of the well. NEW ACCOUNTING PRONOUNCEMENTS - ----------------------------- The Partnerships are not aware of any recently issued accounting pronouncements that would have an impact on the Partnerships' future results of operations and financial position. -23- PROVED RESERVES AND NET PRESENT VALUE - ------------------------------------- The process of estimating oil and gas reserves is complex, requiring significant subjective decisions in the evaluation of available geological, engineering, and economic data for each reservoir. The data for a given reservoir may change substantially over time as a result of, among other things, additional development activity, production history, and viability of production under varying economic conditions; consequently, it is reasonably possible that material revisions to existing reserve estimates may occur in the future. Although every reasonable effort has been made to ensure that these reserve estimates represent the most accurate assessment possible, the significance of the subjective decisions required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures. The following tables summarize changes in net quantities of the Partnerships' proved reserves, all of which are located in the United States, for the periods indicated. The proved reserves were estimated by petroleum engineers employed by affiliates of the Partnerships, and are annually reviewed by an independent engineering firm. "Proved reserves" refers to those estimated quantities of crude oil, gas, and gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known oil and gas reservoirs under existing economic and operating conditions. The following information includes certain gas balancing adjustments which cause the gas volume to differ from the reserve reports prepared by the General Partner. -24- I-D Partnership --------------- Crude Natural Oil Gas (Barrels) (Mcf) --------- ----------- Proved reserves, Dec. 31, 2004 71,201 1,516,243 Production ( 952) ( 41,416) Extensions and discoveries 84 147 Revisions of previous estimates 204 23,496 ------ --------- Proved reserves, March 31, 2005 70,537 1,498,470 Production ( 858) ( 34,823) Extensions and discoveries 305 2,711 Revisions of previous estimates 518 58,832 ------ --------- Proved reserves, June 30, 2005 70,502 1,525,190 Production ( 921) ( 34,746) Extensions and discoveries 41 3,355 Revisions of previous estimates 195 36,001 ------ --------- Proved reserves, Sept. 30, 2005 69,817 1,529,800 ====== ========= -25- I-E Partnership --------------- Crude Natural Oil Gas (Barrels) (Mcf) --------- ----------- Proved reserves, Dec. 31, 2004 500,364 8,079,380 Production ( 10,723) ( 229,046) Extensions and discoveries 363 635 Revisions of previous estimates 20,871 141,088 ------- --------- Proved reserves, March 31, 2005 510,875 7,992,057 Production ( 8,653) ( 195,235) Extensions and discoveries 1,078 13,574 Revisions of previous estimates 3,176 314,743 ------- --------- Proved reserves, June 30, 2005 506,476 8,125,139 Production ( 10,508) ( 189,167) Extensions and discoveries 185 16,674 Revisions of previous estimates 14,074 200,607 ------- --------- Proved reserves, Sept. 30, 2005 510,227 8,153,253 ======= ========= -26- I-F Partnership --------------- Crude Natural Oil Gas (Barrels) (Mcf) --------- ----------- Proved reserves, Dec. 31, 2004 238,894 2,401,195 Production ( 5,079) ( 61,912) Extensions and discoveries 168 296 Revisions of previous estimates 9,588 53,721 ------- --------- Proved reserves, March 31, 2005 243,571 2,393,300 Production ( 3,982) ( 58,488) Extensions and discoveries 407 5,850 Revisions of previous estimates 1,283 139,067 ------- --------- Proved reserves, June 30, 2005 241,279 2,479,729 Production ( 4,785) ( 61,844) Extensions and discoveries 89 7,176 Revisions of previous estimates 5,378 93,024 ------- --------- Proved reserves, Sept. 30, 2005 241,961 2,518,085 ======= ========= The net present value of the Partnerships' reserves may change dramatically as oil and gas prices change or as volumes change for the reasons described above. Net present value represents estimated future gross cash flow from the production and sale of proved reserves, net of estimated oil and gas production costs (including production taxes, ad valorem taxes, and operating expenses) and estimated future development costs, discounted at 10% per annum. The following table indicates the estimated net present value of the Partnerships' proved reserves as of September 30, 2005, June 30, 2005, March 31, 2005, and December 31, 2004. Net present value attributable to the Partnerships' proved reserves was calculated on the basis of current costs and prices as of the date of estimation. Such prices were not escalated except in certain circumstances where escalations were fixed and readily determinable in accordance with applicable contract provisions. The table also indicates the oil and gas prices in effect on the dates corresponding to the reserve valuations. Changes in the oil and gas prices cause the estimates of remaining economically recoverable reserves, as well as the values placed on said reserves to fluctuate. The prices used in calculating the net present value attributable to the Partnerships' proved reserves do not necessarily reflect market prices for oil -27- and gas production subsequent to September 30, 2005. There can be no assurance that the prices used in calculating the net present value of the Partnerships' proved reserves at September 30, 2005 will actually be realized for such production.

The primary source of liquidity and Partnership cash distributions comes from the net revenues generated from the sale of oil and gas produced from the Partnerships' oil and gas properties. The level of net revenues is highly dependent upon the total volumes of oil and natural gas sold. Oil and gas reserves are depleting assets and will experience production declines over time, thereby likely resulting in reduced net revenues. The level of net revenues is also highly dependent upon the prices received for oil and gas sales, which prices have historically been very volatile and may continue to be so. Additionally, lower oil and natural gas prices may reduce the amount of oil and gas that is economic to produce and reduce the Partnerships' revenues and cash flow. Various factors beyond the Partnerships' control will affect prices for oil and natural gas, such as: * Worldwide and domestic supplies of oil and natural gas; * The ability of the members of the Organization of Petroleum Exporting Countries ("OPEC") to agree to and maintain oil prices and production quotas; -28- * Political instability or armed conflict in oil-producing regions or around major shipping areas; * The level of consumer demand and overall economic activity; * The competitiveness of alternative fuels; * Weather conditions and the impact of weather-related events; * The availability of pipelines for transportation; and * Domestic nd foreign government regulations and taxes. It is not possible to predict the future direction of oil or natural gas prices or whether the above discussed trends will remain. Operating costs, including General and Administrative Expenses, may not decline over time or may experience only a gradual decline, thus adversely affecting net revenues as either production or oil and natural gas prices decline. In any particular period, net revenues may also be affected by either the receipt of proceeds from property sales or the incursion of additional costs as a result of well workovers, recompletions, new well drilling, and other events. In addition to pricing, the level of net revenues is also highly dependent upon the total volumes of oil and natural gas sold. Oil and gas reserves are depleting assets and will experience production declines over time, thereby likely resulting in reduced net revenues. Despite this general trend of declining production, several factors can cause the volumes of oil and gas sold to increase or decrease at an even greater rate over a given period. These factors include, but are not limited to, (i) geophysical conditions which cause an acceleration of the decline in production, (ii) the shutting in of wells (or the opening of previously shut-in wells) due to low oil and gas prices (or high oil and gas prices), mechanical difficulties, loss of a market or transportation, or performance of workovers, recompletions, or other operations in the well, (iii) prior period volume adjustments (either positive or negative) made by the purchasers of the production, (iv) ownership adjustments in accordance with agreements governing the operation or ownership of the well (such as adjustments that occur at payout), and (v) completion of enhanced recovery projects which increase production for the well. Many of these factors are very significant as related to a single well or as related to many wells over a short period of time. However, due to the large number of wells owned by the Partnerships, these factors are generally not material as compared to the normal declines in production experienced on all remaining wells. -29- I-D PARTNERSHIP THREE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE THREE MONTHS ENDED SEPTEMBER 30, 2004. Three Months Ended September 30, -------------------------------- 2005 2004 -------- -------- Oil and gas sales $324,886 $229,257 Oil and gas production expenses $ 55,785 $ 30,838 Barrels produced 921 871 Mcf produced 34,746 37,834 Average price/Bbl $ 60.79 $ 41.91 Average price/Mcf $ 7.74 $ 5.09 As shown in the table above, total oil and gas sales increased $95,629 (41.7%) for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. Of this increase, approximately $17,000 and $92,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by a decrease of approximately $16,000 related to a decrease in volumes of gas sold. Volumes of oil sold increased 50 barrels, while volumes of gas sold decreased 3,088 Mcf for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. The decrease in volumes of gas sold was primarily due to normal declines in production, which decrease was partially offset by positive prior period volume adjustments made by the operator on several wells during the three months ended September 30, 2005. Oil and gas production expenses (including lease operating expenses and production taxes) increased $24,947 (80.9%) for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. This increase was primarily due to (i) positive prior period lease operating expense adjustments made on several wells during the three months ended September 30, 2005, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) workover expenses incurred on several other wells during the three months ended September 30, 2005. As a percentage of oil and gas sales, these expenses increased to 17.2% for the three months ended September 30, 2005 from 13.5% for the three months ended September 30, 2004. This percentage increase was primarily due to the dollar increase in oil and gas production expenses. Depreciation, depletion, and amortization of oil and gas properties increased $9,738 (146.9%) for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. Of this increase (i) approximately $7,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of the upward revision in the estimate of the asset retirement obligations, of which approximately $5,000 was related to -30- previously fully depleted wells, and (ii) approximately $1,000 was due to accretion of these additional asset retirement obligations. This increase was also due to one significant well being fully depleted during the three months ended September 30, 2005 due to the lack of remaining reserves. As a percentage of oil and gas sales, this expense increased to 5.0% for the three months ended September 30, 2005 from 2.9% for the three months ended September 30, 2004. This percentage increase was primarily due to the dollar increase in depreciation, depletion, and amortization of oil and gas properties. General and administrative expenses remained relatively constant for the three months ended September 30, 2005 and 2004. As a percentage of oil and gas sales, these expenses decreased to 6.8% for the three months ended September 30, 2005 from 9.6% for the three months ended September 30, 2004. This percentage decrease was primarily due to the increase in oil and gas sales. NINE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE NINE MONTHS ENDED SEPTEMBER 30, 2004. Nine Months Ended September 30, ------------------------------- 2005 2004 -------- -------- Oil and gas sales $882,543 $692,596 Oil and gas production expenses $158,363 $119,681 Barrels produced 2,731 2,558 Mcf produced 110,985 115,934 Average price/Bbl $ 53.57 $ 37.67 Average price/Mcf $ 6.63 $ 5.14 As shown in the table above, total oil and gas sales increased $189,947 (27.4%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. Of this increase, approximately $43,000 and $165,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by a decrease of approximately $25,000 related to a decrease in volumes of gas sold. Volumes of oil sold increased 173 barrels, while volumes of gas sold decreased 4,949 Mcf for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. The decrease in volumes of gas sold was primarily due to normal declines in production. This decrease was partially offset by (i) positive prior period volume adjustments made by the operator on several wells during the nine months ended September 30, 2005, (ii) the first receipt of revenues on one significant well during early 2005, and (iii) the successful completion of several new wells during late 2004 and early 2005. -31- Oil and gas production expenses (including lease operating expenses and production taxes) increased $38,682 (32.3%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. This increase was primarily due to (i) an increase in production taxes associated with the increase in oil and gas sales, (ii) positive prior period lease operating expense adjustments made on several wells during the nine months ended September 30, 2005, and (iii) workover expenses incurred on several other wells during the nine months ended September 30, 2005. As a percentage of oil and gas sales, these expenses increased to 17.9% for the nine months ended September 30, 2005 from 17.3% for the nine months ended September 30, 2004. Depreciation, depletion, and amortization of oil and gas properties increased $8,338 (32.4%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. Of this increase (i) approximately $7,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of the upward revision in the estimate of the asset retirement obligations, of which approximately $5,000 was related to previously fully depleted wells, and (ii) approximately $1,000 was due to accretion of these additional asset retirement obligations. This increase was also due to two significant wells being fully depleted during the nine months ended September 30, 2005 due to the lack of remaining reserves. These increases were partially offset by (i) several wells being fully depleted during the nine months ended September 30, 2004 due to the lack of remaining reserves and (ii) upward revisions in the estimates of remaining oil and gas reserves since September 30, 2004. As a percentage of oil and gas sales, this expense increased to 3.9% for the nine months ended September 30, 2005 from 3.7% for the nine months ended September 30, 2004. General and administrative expenses increased $2,460 (2.9%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. As a percentage of oil and gas sales, these expenses decreased to 9.9% for the nine months ended September 30, 2005 from 12.3% for the nine months ended September 30, 2004. This percentage decrease was primarily due to the increase in oil and gas sales. The Limited Partners have received cash distributions through September 30, 2005 totaling $17,697,175 or 245.98% of Limited Partners' capital contributions. -32- I-E PARTNERSHIP THREE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE THREE MONTHS ENDED SEPTEMBER 30, 2004.

Of this increase, approximately $189,000 and $524,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by a decrease of approximately $87,000 related to a decrease in volumes of gas sold. Volumes of oil and gas sold decreased 643 barrels and 17,292 Mcf, respectively, for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. The decrease in volumes of gas sold was primarily due to normal declines in production. This decrease was partially offset by (i) positive prior period volume adjustments made by the operator on several wells during the three months ended September 30, 2005 and (ii) the successful completion of several new wells during late 2004 and early 2005. Oil and gas production expenses (including lease operating expenses and production taxes) increased $143,678 (53.7%) for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. This increase was primarily due to (i) positive prior period lease operating expense adjustments made on several wells during the three months ended September 30, 2005, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) workover expenses incurred on several other wells during the three months ended September 30, 2005. As a percentage of oil and gas sales, these expenses increased to 19.7% for the three months ended September 30, 2005 from 17.9% for the three months ended September 30, 2004. This percentage increase was primarily due to the dollar increase in oil and gas production expenses. Depreciation, depletion, and amortization of oil and gas properties increased $97,894 (243.9%) for the three months ended September 30, 2005 as compared to the three months ended September 30, 2004. Of this increase (i) approximately $70,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of -33- the upward revision in the estimate of the asset retirement obligations, of which approximately $42,000 was related to previously fully depleted wells, and (ii) approximately $15,000 was due to accretion of these additional asset retirement obligations. This increase was also due to one significant well being fully depleted during the three months ended September 30, 2005 due to the lack of remaining reserves. These increases were partially offset by (i) the decreases in volumes of oil and gas sold and (ii) upward revisions in the estimates of remaining oil and gas reserves since September 30, 2004. As a percentage of oil and gas sales, this expense increased to 6.6% for the three months ended September 30, 2005 from 2.7% for the three months ended September 30, 2004. This percentage increase was primarily due to the dollar increase in depreciation, depletion, and amortization of oil and gas properties. General and administrative expenses remained relatively constant for the three months ended September 30, 2005 and 2004. As a percentage of oil and gas sales, these expenses decreased to 5.8% for the three months ended September 30, 2005 from 8.1% for the three months ended September 30, 2004. This percentage decrease was primarily due to the increase in oil and gas sales. NINE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE NINE MONTHS ENDED SEPTEMBER 30, 2004. Nine Months Ended September 30, ------------------------------- 2005 2004 ---------- ---------- Oil and gas sales $5,628,777 $4,418,764 Oil and gas production expenses $1,101,034 $ 983,429 Barrels produced 29,884 34,394 Mcf produced 613,448 632,401 Average price/Bbl $ 52.63 $ 35.22 Average price/Mcf $ 6.61 $ 5.07 As shown in the table above, total oil and gas sales increased $1,210,013 (27.4%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. Of this increase, approximately $520,000 and $945,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by decreases of approximately $159,000 and $96,000, respectively, related to decreases in volumes of oil and gas sold. Volumes of oil and gas sold decreased 4,510 barrels and 18,953 Mcf, respectively, for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. The decrease in volumes of oil sold was primarily due to (i) normal declines in production and (ii) a negative prior period volume adjustment made by the operator on one significant well during the nine months ended September 30, 2005. The decrease in volumes of gas sold was primarily due to normal declines in production. This decrease was -34- partially offset by (i) an increase in production on two significant wells following the successful workover of those wells during mid 2004, (ii) positive prior period volume adjustments made by the operator on several wells during the nine months ended September 30, 2005, and (iii) the successful completion of several new wells during late 2004 and early 2005. Oil and gas production expenses (including lease operating expenses and production taxes) increased $117,605 (12.0%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. This increase was primarily due to (i) workover expenses incurred on several wells during the nine months ended September 30, 2005, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) positive prior period lease operating expense adjustments made on several other wells during the nine months ended September 30, 2005. These increases were partially offset by (i) a reversal during the nine months ended September 30, 2005 of approximately $89,000 of a charge previously accrued for a judgment and (ii) workover expenses incurred on several wells during the nine months ended September 30, 2004. As a percentage of oil and gas sales, these expenses decreased to 19.6% for the nine months ended September 30, 2005 from 22.3% for the nine months ended September 30, 2004. This percentage decrease was primarily due to the increase in oil and gas sales. Depreciation, depletion, and amortization of oil and gas properties increased $82,058 (55.5%) for the nine months ended September 30, 2005 as compared to the nine months ended September 30, 2004. Of this increase (i) approximately $70,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of the upward revision in the estimate of the asset retirement obligations, of which approximately $42,000 was related to previously fully depleted wells, and (ii) approximately $15,000 was due to accretion of these additional asset retirement obligations. This increase was also due to (i) two significant wells being fully depleted during the nine months ended September 30, 2005 due to the lack of remaining reserves and (ii) downward revisions in the estimates of remaining oil and gas reserves on two other significant wells since September 30, 2004. These increases were partially offset by (i) upward revisions in the estimates of remaining oil and gas reserves since September 30, 2004, (ii) several wells being fully depleted during the nine months ended September 30, 2004 due to the lack of remaining reserves, and (iii) the decreases in volumes of oil and gas sold. As a percentage of oil and gas sales, this expense increased to 4.1% for the nine months ended September 30, 2005 from 3.3% for the nine months ended September 30, 2004. This percentage increase was primarily due to the dollar increase in depreciation, depletion, and amortization of oil and gas properties. -35- General and administrative expenses remained relatively constant for the nine months ended September 30, 2005 and 2004. As a percentage of oil and gas sales, these expenses decreased to 6.9% for the nine months ended September 30, 2005 from 8.8% for the nine months ended September 30, 2004.
