|   | (1) | The Partnership determined that there was an error in the Partnership’s accounting for derivatives for improperly using hedge accounting and for using an incorrect derivative valuation methodology.  Correction of this error required recognition in the statement of operations of an unrealized derivative loss of $313,760, and reversal of a realized loss of $31,111 previously included in oil and gassales during the first quarter of 2005.  The correction also resulted in changes to balance sheet captions as follows:  an increase in “Accounts receivable” of $30,934; a decrease in “Due from Managing General Partner – other, net” of $31,111; a decrease in Accounts payable and accrued expenses of $45,599; an increase in “Due from Managing General Partner – derivatives” (short term) of $3,216; an increase in “Due from Managing General Partner– derivatives” (long term) of $3,813; an increase in “Due to Managing General Partner – derivatives” (short term) of $288,353; an increase in “Due to Managing General Partner – derivatives” (long term) of $1,295; and a decrease in the “Accumulated other comprehensive loss” of $45,422. |

|   | (2) | The Partnership determined that “Oil and gas sales” had been understated for the three month period ended March 31, 2005 by $473,138.  The reversal of the previously recorded incorrect oil and gas revenues accrual and the recording of the correct accrual resulted in changes to the Balance Sheet captions as follows:  an increase in “Accounts receivable” of $579,691; a reductionin “Due from Managing General Partner – other, net” of $44,393; and an increase in “Accounts payable and accrued expenses” of $62,160. |

|   | (3) | The Partnership determined that “Production and operating costs” had been understated by $71,010 for the three month period ended March 31, 2005 with a corresponding understatement of “Accounts payable and accrued expenses” of $71,279 and an overstatement of “Asset retirement obligations” of $269.  In addition, PDC determined that it had also over-withheld productiontaxes from distributions to the limited partners of the Partnership during 2005.  The total error for the production tax over-withholding was $62,023, including $1,332 in forgone interest income, during the three month period ended March 31, 2005.  Properly recording these production taxes resulted in an increase in “Due from Managing General Partner – other, net” of $62,023. |

|   | (4) | The “Depreciation, Depletion and Amortization” error related to Partnership’s wells being assigned to a combined field instead of separate fields.  The calculation of DD&A using two fields resulted in additional DD&A expense of $332,784 during the first quarter of 2005 with a corresponding decrease in oil and gas properties, net at March 31, 2005 of $332,784. |
|--------|-----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (5) | The Partnership used an incorrect starting date for accretion of the asset retirement obligations resulting in an understatement of ”oil and gas properties, net” of $57,256 and “asset retirement obligations” of $58,428 at March 31, 2005 and an understatement of accretion of assets of $1,232 for the three month period ended March 31, 2005. |
|--------|-----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (6) | The Partnership determined that certain invoices in the amount of $1,256 had been improperly recorded during the three months ended March 31, 2005.  Correcting these amounts resulted in an increase in “Oil and gas properties, net” of $173 and a decrease in “Accounts payable and accrued expenses” of $1,083 at March 31, 2005 and a decrease in production and operating costs of $1,256for the three month period ended March 31, 2005. |

|   | · | PDC might sponsor additional drilling programs in the future that could conflict with the interests of the Partnership.  PDC and affiliates have the right to organize and manage oil and natural gas drilling programs in the future similar to the Partnership and to conduct production operations now and in the future on its own behalf or for other individual investor partners.  This situation couldlead to a conflict between the position of PDC as Managing General Partner of the Partnership and the position of PDC or its affiliates as managing general partner or sponsor of additional programs. |

|   | · | PDC has a fiduciary duty as Managing General Partner to the Partnership.  PDC acts as managing general partner currently for 33 limited partnerships, including this Partnership, and is accountable to all of the partnerships as a fiduciary.  PDC therefore has a duty to exercise good faith and deal fairly with the investor partners of each partnership.  PDC’s actions taken on behalfof one or more of these partnerships could be disadvantageous to the Partnership and could fall short of the full exercise of its fiduciary duty to the Partnership. |

|   | (1) | The Partnership determined that there was an error in the Partnership’s accounting for derivatives for improperly using hedge accounting and for using an incorrect derivative valuation methodology.  Correction of this error required recognition in the statement of operations of an unrealized derivative loss of $313,760, and reversal of a realized loss of $31,111 previously included in oil and gassales during the first quarter of 2005.  The correction also resulted in changes to balance sheet captions as follows:  an increase in “Accounts receivable” of $30,934; a decrease in “Due from Managing General Partner – other, net” of $31,111; a decrease in Accounts payable and accrued expenses of $45,599; an increase in “Due from Managing General Partner – derivatives” (short term) of $3,216; an increase in “Due from Managing General Partner– derivatives” (long term) of $3,813; an increase in “Due to Managing General Partner – derivatives” (short term) of $288,353; an increase in “Due to Managing General Partner – derivatives” (long term) of $1,295; and a decrease in the “Accumulated other comprehensive loss” of $45,422. |

|   | (2) | The Partnership determined that “Oil and gas sales” had been understated for the three month period ended March 31, 2005 by $473,138.  The reversal of the previously recorded incorrect oil and gas revenues accrual and the recording of the correct accrual resulted in changes to the Balance Sheet captions as follows:  an increase in “Accounts receivable” of $579,691; a reductionin “Due from Managing General Partner – other, net” of $44,393; and an increase in “Accounts payable and accrued expenses” of $62,160. |

|   | (3) | The Partnership determined that “Production and operating costs” had been understated by $71,010 for the three month period ended March 31, 2005 with a corresponding understatement of “Accounts payable and accrued expenses” of $71,279 and an overstatement of “Asset retirement obligations” of $269.  In addition, PDC determined that it had also over-withheld productiontaxes from distributions to the limited partners of the Partnership during 2005.  The total error for the production tax over-withholding was $62,023, including $1,332 in forgone interest income, during the three month period ended March 31, 2005.  Properly recording these production taxes resulted in an increase in “Due from Managing General Partner – other, net” of $62,023. |

|   | (4) | The “Depreciation, Depletion and Amortization” error related to Partnership’s wells being assigned to a combined field instead of separate fields.  The calculation of DD&A using two fields resulted in additional DD&A expense of $332,784 during the first quarter of 2005 with a corresponding decrease in oil and gas properties, net at March 31, 2005 of $332,784. |

|   | (5) | The Partnership used an incorrect starting date for accretion of the asset retirement obligations resulting in an understatement of ”oil and gas properties, net” of $57,256 and “asset retirement obligations” of $58,428 at March 31, 2005 and an understatement of accretion of assets of $1,232 for the three month period ended March 31, 2005. |

|   | (6) | The Partnership determined that certain invoices in the amount of $1,256 had been improperly recorded during the three months ended March 31, 2005.  Correcting these amounts resulted in an increase in “Oil and gas properties, net” of $173 and a decrease in “Accounts payable and accrued expenses” of $1,083 at March 31, 2005 and a decrease in production and operating costs of $1,256for the three month period ended March 31, 2005. |
