| ·   | 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. |

| ·   | Monthly well supervision fees which are included in production expenses in the Partnership’s Statements of Net Earnings are payable at $975 per well per month for Marcellus wells and $1,500, for New Albany and Indiana Wells. For all other wells a fee of $392 is charged per will per month, for operating and maintaining the wells. Well supervisionfees incurred for the three months and six months ended June 30, 2009 were $203,200 and $257,900, respectively. |

| ·   | Transportation fees which are included in production expenses in the Partnership's Statements of Net Earnings are generally payable at 13% of the natural gas sales price.

| ·   | 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. |
