|   | (1) | The accounts receivable error of $252,193 related to an adjustment to record actual for previously estimated natural gas and oil sales revenue of $319,682 offset by the reclassification of unrealized derivative gains of $67,489 to Due to Managing General Partner – derivatives at December 31, 2004. |
|--------|-----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (2) | The Due to Managing General Partner – other, net error of $71,515 related to the correction of over withheld production taxes of $345,985 recorded to natural gas and oil production costs together with $9,931 of accrued interest income thereon offset by the accrual of natural gas and oil production costs of $284,401 at December 31, 2004. |
|--------|-----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (3) | The oil and natural gas properties error of $13,464,930 related to the recognition of $12,317,924 recorded as a loss on impairment of oil and gas properties, a $1,279,572 reduction to accumulated DD&A in conjunction with recording the impairment and an increase of $132,566 related to the understatement of asset retirement obligations described in (7) below.  The impairment expense resulted from the Partnership’s properties being divided into two separate fields for the purposes of assessment for impairment from the previously inappropriate one field approach.  The impairment assessment for the Partnership’s Grand Valley Field in the Piceance Basin could not support the current carrying value of its wells based on undiscounted cash flows and thus an impairment occurred.  The impairment resulted from the Partnership reducing the carrying value of this field to an amount equal to the future discounted cash flows. |

|   | (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 a realized and an unrealized derivative loss of $108,203, and reclassification of a realized loss of $98,532 previously included in natural gas and oil sales during the first quarter of 2005.  The correction also resulted in changes to balance sheet captions as follows:  an increase in “Accounts receivable” of $81,605; an increase in “Due from Managing General Partner – derivatives” (short term) of $17,151; a decrease in “Due from Managing General Partner – other, net” of $16,136; an increase in “Due from Managing General Partner – derivatives” (long term) of $2,823; an increase in “Accounts payable and accrued expenses” of $88,149; an increase in “Due to Managing General Partner – derivatives” (short term) of $28,686; an increase in “Due to Managing General Partner – derivatives” (long term) of $959; and an increase in the “Accumulated other comprehensive loss” of $22,680. |

|   | (2) | The Partnership determined that natural gas and oil revenues had been overstated for the three month period ended March 31, 2005 by $23,121 and production and operating costs were overstated by $4,699.  The reversal of the previously recorded incorrect natural gas and oil revenues accrual and the recording of the correct accrual resulted in changes to the Balance Sheet captions as follows:  a decrease in “Accounts receivable” of $51,783; an increase in “Due from Managing General Partner – other, net” of $143,771; and an increase in “Accounts payable and accrued expenses” of $110,410. |

|   | (3) | PDC determined that it had also over-withheld production taxes from distributions to the limited partners of the Partnership during 2005.  The total error for the production tax over-withholding was $73,387, including $5,665 in forgone interest income, during the three month period ended March 31, 2005.  Properly recording these costs resulted in an increase in “Due from Managing General Partner – other, net” of $73,387. |
|--------|-----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (4) | The “Depreciation, depletion and amortization” error related to Partnership’s wells being assigned to one combined field instead of two separate fields.  This resulted in the recognition of impairment expense at December 31, 2004, which is included in the restatement adjustment to Partners’ equity at January 1, 2005.  The revised calculation of DD&A using two fields resulted in additional DD&A expense of $100,844 during the first quarter of 2005 with a corresponding decrease in “Natural gas and oil properties, net” at March 31, 2005 of $100,844. |

|   | (5) | The Partnership also used an incorrect starting date for accretion of the asset retirement obligation resulting in an understatement of “Accretion of asset retirement obligations” of $2,413 offset by a reduction in “Direct costs – general and administration” of $257.  Recording the additional accretion resulted in an increase to the Balance Sheet caption “Asset retirement obligations” of $2,156. |

|   | (6) | Represents the reclassification of $581,838 of “Accounts receivable” for undistributed natural gas and oil revenues collected by the Managing General Partner from the Partnership’s customers from “Accounts receivable” to “Due from Managing General Partner – other, net” offset by the reclassification of $26,666 of “Accounts payable and accrued expenses” for natural gas and oil production costs to “Due from Managing General Partner – other, net” to conform to the 2007 current year presentation. |

|   | · | The U.S. Environmental Protection Agency, or EPA, has recently focused on citizen concerns about the risk of water contamination and public health problems from drilling and hydraulic fracturing activities.  The EPA has held public meetings around the country on this issue that have been well publicized and well attended.  This renewed focus could lead to additional federal and state laws and regulations affecting the Partnership’s well recompletions, fracturing and operations.  Additional laws, regulations or other changes could significantly reduce the Partnership’s future Codell formation development opportunities, increase the Partnership’s costs of operations, and reduce the Partnership’s distributable cash flows, in addition to undermining the demand for the natural gas and oil the Partnership produces. |

|   | · | Several bills in Congress, if passed, would establish a "cap and trade" system regarding greenhouse gas emissions.  Companies would be assigned emission "allowances" under these bills which would decline each year.  In addition, new EPA greenhouse gas monitoring and reporting regulations may affect us and the third parties that process our natural gas and oil. |
|--------|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | New or increased severance taxes have been proposed in several states, which could adversely affect the existing operations in these states and the economic viability of future well completions. |
|--------|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was signed into law.  The Dodd-Frank Act regulates derivative transactions, including the Partnership’s natural gas and oil hedging swaps.  These swaps are broadly defined to include most of the Partnership’s hedging instruments.  The law requires the issuance of new regulations and administrative procedures related to derivatives within one year.  The effect of such future regulations on the Partnership’s business is currently uncertain.  In particular, note the following: |
|--------|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | i. | The Dodd-Frank Act may decrease the Managing General Partner’s ability to enter into hedging transactions which would expose the Partnership to additional risks related to commodity price volatility.  Commodity price decreases could then have an immediate significant adverse affect on the Partnership’s revenues and impair the Partnership’s ability to have certainty with respect to a portion of the Partnership’s distributable cash flows.  A reduction in cash flows may lead to decreased Investor Partner cash distributions or fewer well recompletions and therefore, decreased Partnership’s proved reserves and future production. |
|--------|----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | ii. | The Managing General Partner expects that the cost to hedge will increase as a result of fewer counterparties in the market and the pass-through of increased counterparty costs.  The Partnership’s derivative counterparties may be subject to significant new capital, margin and business conduct requirements imposed as a result of the new legislation. |
|--------|-----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | iii. | The Dodd-Frank Act contemplates that most swaps will be required to be cleared through a registered clearing facility and traded on a designated exchange or swap execution facility.  There are some exceptions to these requirements for entities that use swaps to hedge or mitigate commercial risk.  While the Partnership may ultimately be eligible for such exceptions, the scope of these exceptions currently is somewhat uncertain, pending further definition through rulemaking proceedings. |
|--------|------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | iv. | The above factors could also affect the pricing of derivatives and make it more difficult for the Managing General Partner to enter into hedging transactions on behalf of the Partnership, on favorable terms. |

|   | · | PDC has no plans through 2010 or beyond to sponsor additional drilling programs; however joint ventures arrangements could conflict with the interests of the Partnership.  PDC and affiliates have the right to organize and manage natural gas and oil joint venture arrangements, whose business purpose is generally similar to the Partnership, and to conduct production operations now and in the future on its own behalf or for joint venture partners.  This situation could lead to a conflict between the position of PDC as Managing General Partner of the Partnership and the position of PDC or its affiliates as a capital contributing partner to joint venture natural gas and oil properties development entity. |
|--------|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | 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 behalf of 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. |
|--------|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | There are and will continue to be transactions between PDC, its affiliates and the Partnership.  PDC, as operator of the Partnership, has and will continue to provide drilling, completion and operation services to the Partnership’s wells.  Although the prices that PDC has charged, and will charge, to the Partnership for the supplies and services provided by PDC and affiliates to the Partnership will be competitive with the prices charged by unaffiliated persons for the same supplies and services, PDC will benefit financially from this relationship. |

|   | · | In operating the Partnership, the Managing General Partner and its affiliates could take actions which benefit themselves and which do not benefit the Partnership.  These actions could result in the Partnership being less profitable.  In that event, Investor Partners could anticipate a reduction of cash distributions. |
|--------|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | PDC, the managing general partner of various public limited partnerships, has disclosed its intention to pursue the acquisition, within the next three years beginning in the fall of 2010, of the remaining third-party Investor Partner interests in the limited partnerships which PDC has sponsored, which includes the Partnership.  Any such transaction, if proposed, will also be subject to PDC having sufficient available capital.  Should a purchase offer from PDC be proposed, approved by a majority of the respective partnership’s unaffiliated limited partners, and consummated, the purchase transaction would result in a liquidating cash distribution to all partners and termination of the existence of that partnership.  There is no assurance that any such acquisition of any or all of PDC’s sponsored drilling program partnerships will occur. For additional information regarding PDC’s disclosed partnership acquisition intensions, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations−PDC Sponsored Drilling Program Acquisition Plan. |

|   | · | “Collars” contain a fixed floor price (put) and ceiling price (call).  If the index price falls below the fixed put strike price, PDC, as Managing General Partner, receives the market price from the purchaser and receives the difference between the put strike price and index price from the counterparty.  If the index price exceeds the fixed call strike price, PDC, as Managing General Partner, receives the market price from the purchaser and pays the difference between the call strike price and index price to the counterparty.  If the index price is between the call and put strike price, no payments are due to or from the counterparty. |

|   | · | “Swaps” are arrangements that guarantee a fixed price.  If the index price is below the fixed contract price, PDC, as Managing General Partner, receives the market price from the purchaser and receives the difference between the index price and the fixed contract price from the counterparty.  If the index price is above the fixed contract price, PDC, as Managing General Partner, receives the market price from the purchaser and pays the difference between the index price and the fixed contract price to the counterparty.  If the index price and contract price are the same, no payment is due to or from the counterparty. |

|   | · | “Basis protection swaps” are arrangements that guarantee a price differential for natural gas from a specified delivery point.  For CIG basis protection swaps, which traditionally have negative differentials to NYMEX, PDC, as Managing General Partner, receives a payment from the counterparty if the price differential is greater than the stated terms of the contract and pays the counterparty if the price differential is less than the stated terms of the contract.  If the index price and contract price are the same, no payment is due to or from the counterparty. |

|   | · | “Floors” contain a floor price (put) whereby PDC, as Managing General Partner, receives the market price from the purchaser and the difference between the index price and floor strike price from the counterparty if the index price falls below the floor strike price, but receives no payment when the index price exceeds the floor strike price. |

|   | 1. | The following material weaknesses in internal control over financial reporting were identified by Management which related to the year ended December 31, 2004, and the subsequent period through December 28, 2007, as follows: |
|--------|----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The Registrant did not have effective policies and procedures, or personnel with sufficient technical expertise to properly account for derivative transactions in accordance with generally accepted accounting principles. Specifically, the Registrant's policies and procedures relating to derivatives transactions were not designed effectively such that each of the requirements for hedge accounting were evaluated appropriately with respect to the Registrant's commodity based derivatives. |
|--------|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The Registrant did not have effective policies and procedures, or personnel with sufficient technical expertise to ensure compliance with appropriate accounting principles for its natural gas and oil properties. Specifically, the Registrant's policies and procedures were not designed effectively to ensure that the calculation of depreciation and depletion and the determination of impairments were performed in accordance with the applicable authoritative accounting guidance. |
|--------|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The Registrant did not have effective policies and procedures, or personnel with sufficient technical expertise to ensure that its accounting for asset retirement obligations complied with generally accepted accounting principles. Specifically, the Registrant's policies and procedures regarding the estimate of the fair value of the asset retirement obligations were not designed effectively to ensure that it was estimated in accordance with SFAS No. 143, Asset Retirement Obligations. |
|--------|--------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The Registrant did not have effective policies and procedures to ensure the timely reconciliation, review and adjustment of significant balance sheet and income statement accounts, which resulted in the identification of material misstatements in certain significant balance sheet and income statement accounts during the Registrant's closing process. |
|--------|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 2. | In connection with KPMG's audit of the Managing General Partner's 2006 financial statements, the Managing General Partner, identified that the Managing General Partner had over-withheld production taxes from revenue distributions made to its 75 drilling partnerships' limited partners, including the limited partners of the Registrant.  See Explanatory Note on Page 1 for discussion concerning the over-withholding of production taxes by PDC. |

|--------|--------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The support for the Partnership’s general ledger depends in part on the effectiveness of controls of the Managing General Partner’s spreadsheets.  The overall ineffectiveness of the Managing General Partner's spreadsheet controls could have a material effect on the Partnership’s financial statements.  The Partnership did not maintain effective controls to ensure the completeness, accuracy, and validity of key financial statement spreadsheets generated by the Managing General Partner.  These spreadsheets are utilized by the Partnership to support significant balance sheet and income statement accounts. |
|--------|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The support for the Partnership’s derivative calculations depends in part on the effectiveness of controls of the Managing General Partner’s process.  The overall ineffectiveness of the Managing General Partner's derivative controls could have a material effect on the Partnership’s financial statements.  The Partnership did not maintain effective controls to ensure that the Managing General Partner had policies and procedures, or personnel with sufficient technical expertise to record derivative activities in accordance with generally accepted accounting principles. |
|--------|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | For the transactions that are directly related to and processed by the Partnership, the Partnership failed to maintain sufficient documentation to adequately assess the operating effectiveness of internal control over financial reporting.  More specifically, the Partnership’s financial close and reporting narrative failed to adequately describe the process, identify key controls and assess segregation of duties. |
|--------|--------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | · | The Partnership did not have effective policies and procedures, or personnel with sufficient technical expertise to ensure compliance with appropriate accounting principles for its natural gas and oil properties.  Specifically, the Partnership’s policies and procedures were not designed effectively to ensure that the calculation of depreciation and depletion and the determination of impairments were performed in accordance with the applicable authoritative accounting guidance.  This material weakness was remediated as of December 31, 2007. |

|   | (3) | The oil and natural gas properties error of $13,464,930 related to the recognition of $12,317,924 recorded as a loss on impairment of oil and gas properties, a $1,279,572 reduction to accumulated DD&A in conjunction with recording the impairment and an increase of $132,566 related to the understatement of asset retirement obligations described in (7) below.  The impairment expense resulted from the Partnership’s properties being divided into two separate fields for the purposes of assessment for impairment from the previously inappropriate one field approach.  The impairment assessment for the Partnership’s Grand Valley Field in the Piceance Basin could not support the current carrying value of its wells based on undiscounted cash flows and thus an impairment occurred.  The impairment resulted from the Partnership reducing the carrying value of this field to an amount equal to the future discounted cash flows. |

|   | (4) | The accumulated depreciation, depletion and amortization (DD&A) error related to a decrease in accumulated DD&A of $1,279,572 resulting from the impairment described in (3) above and a net $238,517 decrease in accumulated DD&A resulting from an increase related to the Partnership’s wells being assigned to one combined field instead of two separate fields offset by a decrease, resulting from the impairment, which occurred in the first quarter of 2004. |

The Partnership determined that its derivatives did not qualify for hedge accounting and unrealized gains or losses should be recognized in the Statement of Operations at December 31, 2004.  Upon restatement of the balance sheet at December 31, 2004, AOCI is eliminated and changes in fair value of open derivative positions are recorded in retained earnings. |

|   | · | “Collars” contain a fixed floor price (put) and ceiling price (call).  If the index price falls below the fixed put strike price, PDC, as Managing General Partner, receives the market price from the purchaser and receives the difference between the put strike price and index price from the counterparty.  If the index price exceeds the fixed call strike price, PDC, as Managing General Partner, receives the market price from the purchaser and pays the difference between the call strike price and index price to the counterparty.  If the index price is between the call and put strike price, no payments are due to or from the counterparty. |

|   | (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 a realized and an unrealized derivative loss of $108,203, and reclassification of a realized loss of $98,532 previously included in natural gas and oil sales during the first quarter of 2005.  The correction also resulted in changes to balance sheet captions as follows:  an increase in “Accounts receivable” of $81,605; an increase in “Due from Managing General Partner – derivatives” (short term) of $17,151; a decrease in “Due from Managing General Partner – other, net”; an increase in “Due from Managing General Partner – derivatives” (long term) of $2,823; an increase in “Accounts payable and accrued expenses” of $88,149; an increase in “Due to Managing General Partner – derivatives” (short term) of $28,686; an increase in “Due to Managing General Partner – derivatives” (long term) of $959; and an increase in the “Accumulated other comprehensive loss” of $22,680. |

|   | (2) | The Partnership determined that natural gas and oil revenues had been overstated for the three month period ended March 31, 2005 by $23,121 and production and operating costs were overstated by $4,699.  The reversal of the previously recorded incorrect natural gas and oil revenues accrual and the recording of the correct accrual resulted in changes to the Balance Sheet captions as follows:  a decrease in “Accounts receivable” of $51,783; an increase in “Due from Managing General Partner – other, net” of $143,771; and an increase in “Accounts payable and accrued expenses” of $110,410. |

|   | (3) | PDC determined that it had also over-withheld production taxes from distributions to the limited partners of the Partnership during 2005.  The total error for the production tax over-withholding was $73,387, including $5,665 in forgone interest income, during the three month period ended March 31, 2005.  Properly recording these costs resulted in an increase in “Due from Managing General Partner – other, net” of $73,387. |

|   | (4) | The “Depreciation, depletion and amortization” error related to Partnership’s wells being assigned to one combined field instead of two separate fields.  This resulted in the recognition of impairment expense at December 31, 2004, which is included in the restatement adjustment to Partners’ equity at January 1, 2005.  The revised calculation of DD&A using two fields resulted in additional DD&A expense of $100,844 during the first quarter of 2005 with a corresponding decrease in “Natural gas and oil properties, net” at March 31, 2005 of $100,844. |

|   | (5) | The Partnership also used an incorrect starting date for accretion of the asset retirement obligation resulting in an understatement of “Accretion of asset retirement obligations” of $2,413 offset by a reduction in “Direct costs – general and administration” of $257.  Recording the additional accretion resulted in an increase to the Balance Sheet caption “Asset retirement obligations” of $2,156. |

|   | (6) | Represents the reclassification of $581,838 of “Accounts receivable” for undistributed natural gas and oil revenues collected by the Managing General Partner from the Partnership’s customers from “Accounts receivable” to “Due from Managing General Partner – other, net” offset by the reclassification of $26,666 of “Accounts payable and accrued expenses” for natural gas and oil production costs to “Due from Managing General Partner – other, net” to conform to the 2007 current year presentation. |
