| -   | Water production increased by 6.2% for the year ended December 31, 2010.  The increase in production was due to more favorable weather during the second and third quarters of 2010 when compared to the same periods of 2009.  During these two quarters, when the weather is warm and dry, residential customers are more likely to use more water.  During 2009, the Town of Windsor Locks, CT, part of our largest service area, saw 102 days of rain compared to 77 days in 2010.  During the six month period of April through September 2010, the Company’s water production increased by approximately 13%, when compared to the same six month period of 2009. |

| -   | Labor costs increased in 2010 primarily due to a larger component of 2009 labor costs being capitalized as part of the implementation of a new Enterprise Resource Planning (ERP) system; |
|---------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Water treatment costs increased due to higher costs associated with laboratory testing and waste disposal.  Additionally, the costs of chemicals increased when compared to 2009 due to higher prices and an increase in water production; |
|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Pension and post-retirement medical costs increased due primarily to a decrease in the discount rate used to determine the future liabilities of the plans and, partially, to a decline in the market value of the plans’ assets in prior periods; and |
|---------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Customer costs increased due to higher bad debt expense.  This was driven by a higher Accounts Receivable balance at December 31, 2010, when compared to 2009, due to higher consumption and higher rates in effect during the second half of 2010 and due to an increase in accounts receivable aged over 180 days, due in part to employees focusing on bill integrity with the implementation of the ERP system in the first quarter of 2010.  These increases to Customer costs were partially offset by a decrease in customer communication and postage costs. |
|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Outside services decreased due to a reduction in legal fees associated with the favorable resolution of an on-going legal matter in our Unionville decision during 2010 and a reduction in temporary labor used as part of cost containment; and |
|---------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Medical costs decreased 23% due to a reduction in claims and administrative expense as well as an increase in the amount contributed by employees through payroll deductions.  While the Company has taken steps to manage its medical costs by offering a wider variety of plans, including a high-deductible health plan, and passing some cost increases on to employees, it is difficult to project future costs as they are primarily dependant on claims made by employees in any given year. |

| -   | On July 1, 2009, the Company’s first WICA surcharge and the voluntarily enacted rate decrease, became effective.  The net effect of these two new items on customers’ bills was a decrease to operating revenue of approximately $287,000, or approximately 15% of the total year over year decrease in customer revenues.  WICA charges will continue to appear on customer’s bills until the Company’s next general rate case, including increases to WICA charges between cases, while the rate reduction was eliminated on January 1, 2010. |

| -   | Water production for the year ended December 31, 2009 decreased by 4%.  A portion of this decline was related to lower residential demand due to the extremely wet and cool weather experienced in the second quarter of 2009.  In addition, our residential customers continued the declining usage throughout 2009. |
|---------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Industrial revenues decreased by $363,000, or 20%, to $1,459,000 when compared to 2008, primarily due to the economic downturn affecting companies in our service regions.  A portion of the decrease was due to industrial customers cutting back on shifts and other budget cuts. |
|---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | Partially offsetting the declining usage described above, was the implementation of the second phase of the Company’s 2006 rate increase that was effective April 1, 2008.  As a result, the first quarter of 2009 included an increase of rates of approximately 4.5% that was not included in rates in the first quarter of 2008. |
|---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| -   | The January 2009 acquisition of Ellington Acres added approximately $261,000 in new revenues from the additional customers served. |
