| ·   | Gas      distribution operating income increased $19.1 million for the third      quarter 2009 compared to the prior-year period.  The three-month      results reflected: |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | - | Higher      gas distribution margin (approximately $20 million) due primarily to the      base rate increase. |
|--------|---|---------------------------------------------------------------------------------------------------------------|

|   | - | Lower      operating and maintenance costs ($0.9 million) due in large part to      decreased company use and storage-related gas costs and bad debt expense,      partially offset by increased pensionexpense. |
|--------|---|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | - | Partially      offsetting these positive factors was higher depreciation expense ($1.6      million). |

| ·   | Gas      distribution operating income increased $15.0 million for the nine months      ended September 30, 2009 compared to the prior-year period.  The      nine-month results reflected: |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | - | Higher      gas distribution margin (approximately $31 million) due to the base rate      increase (approximately $45 million) partially offset by lower demand      unrelated to weather (approximately $6 million), lower franchise gas cost      recoveries (approximately $3 million), and lower natural gas deliveries      due to warmer weather in 2009 (approximately $2  million). |
|--------|---|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | - | Higher      operating and maintenance costs ($10.5 million) due primarily to higher      payroll and benefit-related costs (primarily attributable to increased      pension expense) and the absence of prior year legal recoveries recorded      in the second quarter of 2008.  These increases were partially      offset by lower bad debt expense (attributable principally to lower      natural gas prices) and lower franchise gas  costs. |
|--------|---|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | - | Higher      depreciation expense ($4.9million). |

| ·   | Shipping      operating income decreased $2.9 million and $3.4 million for the third      quarter 2009 and the nine months ended September 30, 2009, respectively,      compared to the prior-year periods.  Declines in both periods      were due to lower operating revenues partially offset by lower      operating costs.  Decreased operating revenues for both 2009      periods, compared to 2008, were attributable to lower volumes shipped and      lower average rates (resulting principally from lower surcharges for      fuel).  Decreased operating costs for both 2009 periods,      compared to 2008, were primarily attributable to lower      transportation-related costs (due in large part to lower volumes shipped      and lower fuel prices); and lower chartercosts. |

| ·   | Other      energy ventures operating income increased $3.1 million and $6.4 million      for the third quarter 2009 and the nine months ended September 30, 2009,      respectively, compared to the prior-year periods due primarily to higher      operating income in the company’s retail energy-related products and      services businesses; and wholesale natural gas marketing      business. |

| ·   | The      third quarter 2009 financial results, compared to the same period in 2008,      reflect lower pretax equity investment income due primarily to the absence      of equity income from EN Engineering.  The nine-months-ended      September 30, 2009 financial results, compared to the same period in 2008,      reflect lower interest income (due primarily to lower average rates, lower      average investment balances, and lower interest on tax matters), and a      higher effective income tax rate; partially offset by higher pretax equity      investment income.  Higher equity investment income was due      primarily to a gain of $10.1 million pretax, recorded in the first quarter      of 2009, related to the sale of the company’s equity investment interest      in EN Engineering. |
