| ·   | Introduce a new definition of oil and gas producing activities. This new definition allows companies to include in their reserve base volumes from unconventional resources. Such unconventional resources include bitumen extracted from oil sands and oil and gas extracted from coal beds and shale formations. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Report oil and gas reserves using an unweighted average price using the prior 12-month period, based on the closing prices on the first day of each month, rather than year-end pricing. This should maximize the comparability of reserve estimates among companies and mitigate the distortion of the estimates that arises when using a single pricing date. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Permit companies to disclose their probable and possible reserves on a voluntary basis. Current rules limit disclosure to only proved reserves. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Update and revise reserve definitions to reflect changes in the oil and gas industry and new technologies. New updated definitions include “by geographic area” and “reasonable certainty.” |
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Permit the use of new technologies to determine proved reserves if those technologies have been demonstrated empirically to lead to reliable conclusions about reserves volumes. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Require additional disclosures regarding the qualifications of the chief technical person who oversees the Partnership’s overall reserve estimation process. Additionally, disclosures are required related to internal controls over reserve estimation, as well as a report addressing the independence and qualifications of a Partnership’s  reservespreparer or auditor based on Society of Petroleum Engineers criteria. |

| (2)   | Average sales prices represent accrual basis pricing after reversing the effect of previously recognized gains resulting from prior period impairment charges. |
|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (3)   | Average gas prices are calculated by including in total revenue gains previously recognized into income and dividing by the total volume for the period. Gas revenue was adjusted for previously recognized gains of $189,200 and $122,800 for the three and six months June 30, 2009. Gas revenue was adjusted for previously recognized gains of $251,400 and $246,500for the three and six months ended June 30, 2008. |

| ·   | Introduce a new definition of oil and gas producing activities. This new definition allows companies to include in their reserve base volumes from unconventional resources. Such unconventional resources include bitumen extracted from oil sands and oil and gas extracted from coal beds and shale formations. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Report oil and gas reserves using an unweighted average price using the prior 12-month period, based on the closing prices on the first day of each month, rather than year-end pricing. This should maximize the comparability of reserve estimates among companies and mitigate the distortion of the estimates that arises when using a single pricing date. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Permit companies to disclose their probable and possible reserves on a voluntary basis. Current rules limit disclosure to only proved reserves. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Update and revise reserve definitions to reflect changes in the oil and gas industry and new technologies. New updated definitions include “by geographic area” and “reasonable certainty.” |
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Permit the use of new technologies to determine proved reserves if those technologies have been demonstrated empirically to lead to reliable conclusions about reserves volumes. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Require additional disclosures regarding the qualifications of the chief technical person who oversees the Partnership’s overall reserve estimation process. Additionally, disclosures are required related to internal controls over reserve estimation, as well as a report addressing the independence and qualifications of a Partnership’s reservespreparer or auditor based on Society of Petroleum Engineers criteria. |
