Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

Unitil Corporation (Unitil or the Company) is a public utility holding company. Unitil’s principal business is the retail distribution of electricity and natural gas through two utility subsidiaries: Unitil Energy System’s Inc. (UES) and Fitchburg Gas and Electric Light Company (FG&E). UES is an electric utility with an operating franchise in the southeastern seacoast and capital city areas of New Hampshire. FG&E is a combination gas and electric utility with an operating franchise in the greater Fitchburg area of north central Massachusetts.

Unitil’s two retail distribution utilities serve approximately 99,400 electric customers and 15,000 natural gas customers in their franchise areas. The retail distribution companies are pure distribution utilities with a combined investment in net utility plant of $249.4 million at March 31, 2008. Substantially all of Unitil’s revenue and earnings are derived from regulated utility operations.

Unitil also conducts non-regulated operations principally through its Usource™ (Usource) subsidiary. Usource provides energy brokering and consulting services to large commercial and industrial customers in the northeastern United States. Unitil’s other subsidiaries include Unitil Service and Unitil Realty, which provide centralized facilities, management and administrative services to Unitil’s affiliated companies. Unitil’s consolidated net income includes the earnings of the holding company and these subsidiaries.

On February 15, 2008, the Company entered into a Stock Purchase Agreement (Agreement) with NiSource Inc. (NiSource) and Bay Sate Gas Company (Bay State, which is a wholly owned utility subsidiary of NiSource), to acquire all of the outstanding stock of Northern Utilities, Inc. (Northern), and Granite State Gas Transmission, Inc. (Granite) for $160 million plus a net working capital adjustment. Northern’s principal business is the retail distribution of natural gas to approximately 53,000 customers located in 44 coastal New Hampshire and southern Maine communities. Portions of Northern’s natural gas service territory are contiguous and overlapping with Unitil’s electric distribution service territory in New Hampshire. Granite’s principal business is a natural gas transmission company, principally engaged in the business of rendering natural gas transportation services to Northern.

Consummation of the acquisition is subject to various closing conditions, including but not limited to the receipt of requisite regulatory approvals from certain federal and state public utility, antitrust and other regulatory authorities. It is currently anticipated that the acquisition will be consummated in the fourth quarter of 2008. However, no assurance can be given that the acquisition will occur, or, the timing of its completion.

RATES AND REGULATION

Unitil’s utility operations related to wholesale and interstate business activities are regulated by the Federal Energy Regulatory Commission (FERC). The retail distribution utilities, UES and FG&E, are subject to regulation by the New Hampshire Public Utilities Commission (NHPUC) and the Massachusetts Department of Public Utilities (MDPU), formerly the Massachusetts Department of Telecommunications and Energy, respectively, in regards to their rates, issuance of securities and other accounting and operational matters. Because Unitil’s primary operations are subject to rate regulation, the regulatory treatment of various matters could significantly affect the Company’s operations and financial position.

Unitil’s retail distribution utilities have the franchise to deliver electricity and/or natural gas to all customers in their franchise areas, at rates established under traditional cost of service regulation. Under this regulatory structure, UES and FG&E recover the cost of providing distribution service to their customers based on a historical test year, in addition to earning a return on their capital investment in utility assets.

As a result of the implementation of retail choice in New Hampshire and Massachusetts, Unitil’s customers are free to contract for their supply of electricity with third-party suppliers. The retail distribution utilities provide for the delivery of that supply of electricity over their distribution systems at regulated rates. Both UES and FG&E

continue to provide basic or default electric supply service to those customers who do not obtain their supply from third-party suppliers, with the costs associated with electricity supplied by the Company being recovered on a pass-through basis under periodically-adjusted rates.

As a result of the introduction of retail choice for all natural gas customers in Massachusetts, FG&E’s customers are free to contract for their supply of natural gas with third-party suppliers. FG&E continues to provide natural gas supply services to those customers who do not obtain their supply from third-party suppliers. The costs associated with natural gas supplied by FG&E are recovered on a pass-through basis under periodically adjusted rates.

RESULTS OF OPERATIONS

The following section of MD&A compares the results of operations for each of the two fiscal periods ended March 31, 2008 and March 31, 2007 and should be read in conjunction with the accompanying Consolidated Financial Statements and the accompanying Notes to Consolidated Financial Statements included in Item 1 of this report.

Earnings Overview

The Company’s Earnings Applicable to Common Shareholders (Net Income) was $3.3 million for the first quarter of 2008. Earnings per common share (EPS) were $0.57 for the three months ended March 31, 2008, an improvement of $0.11 per share or 24% over the first quarter of 2007.

Unitil’s improved first quarter earnings in 2008 over 2007 were driven by higher gas sales margin and lower operating expenses, including the benefit from the proceeds of an insurance settlement associated with environmental remediation costs. These favorable factors were partially offset by higher amortization expenses and higher interest expense in the current year.

The following table presents the significant items contributing to the improvement in earnings per share in the first quarter of 2008 compared to the same period in 2007:


	Earnings Per Share
Three Months Ended March 31, 2007:	$	0.46
Electric Sales Margin		(0.04	)
Gas Sales Margin		0.10
Usource Sales Margin		0.01
Operation & Maintenance Expense		0.19
Depreciation, Amortization, Taxes & Other		(0.10	)
Interest Expense, net		(0.05	)

Three Months Ended March 31, 2008:	$	0.57

In the first quarter of 2008, Unitil’s electric kilowatt (kWh) sales decreased 1.4% compared to the same period in 2007. Gas sales in the first quarter of 2008 decreased 1.7% compared to the same period in 2007. The lower unit sales in 2008 compared to 2007 were driven by milder winter weather this year and lower average usage by our customers reflecting a slowing economy and energy conservation.

Electric sales margin was lower by $0.4 million in the three months ended March 31, 2008 compared to the same period in 2007 due to lower electric kWh sales volumes, partially offset by higher electric base rates. Gas sales margin increased $0.9 million in the three months ended March 31, 2008 compared to the same period in 2007 reflecting higher gas base rates, implemented in 2007. Usource, our non-regulated energy brokering business, recorded increased sales margin of $0.1 million in the first quarter of 2008, an increase of 11% over the first quarter of 2007.

Total Operation & Maintenance (O&M) expenses decreased $1.8 million for the three month period ended March 31, 2008 compared to the same period in 2007. This decrease reflects a reduction to operating expenses of $2.8 million from the proceeds of an insurance settlement associated with environmental remediation costs. This reduction to operating expenses was partially offset by annual increases in salary, wage and benefit costs of $0.7 million, higher professional fees of $0.2 million and higher bad debt expenses of $0.1 million.

Depreciation, Amortization, Taxes & Other expenses increased $1.2 million in the three month period ended March 31, 2008 compared to the same period in 2007 primarily reflecting the amortization of $0.7 million of natural gas inventory carrying costs and higher income taxes on higher levels of pre-tax earnings in 2008 compared to 2007.

Interest Expense, Net increased $0.5 million in the three month period ended March 31, 2008 compared to the same period in 2007 primarily reflecting higher debt outstanding.

In 2007, Unitil’s annual common dividend was $1.38, representing an unbroken record of quarterly dividend payments since trading began in Unitil’s common stock. At its January, 2008 and March, 2008 meetings, the Unitil Board of Directors declared quarterly dividends on the Company’s common stock of $0.345 per share.

A more detailed discussion of the Company’s results of operations for the three months ended March 31, 2008 and a period-to-period comparison of changes in financial position are presented below.

Balance Sheet

The Company’s investment in Net Utility Plant increased by $11.7 million as of March 31, 2008 compared to March 31, 2007. This increase was due to capital expenditures related to UES’ and FG&E’s electric and gas distribution systems, including expenditures of approximately $1.0 million for the Company’s Advanced Metering Infrastructure (AMI) project.

Regulatory Assets decreased $29.0 million as of March 31, 2008 compared to March 31, 2007, primarily reflecting current year cost recoveries. A significant portion of this decrease is matched by a corresponding decrease of $19.9 million in Power Supply Contract Obligations. The remaining decrease primarily reflects lower levels of Regulatory Assets associated with deferred taxes and retirement benefit obligations as well as recoveries of deferred charges.

Long-Term Debt increased $19.6 million as of March 31, 2008 compared to March 31, 2007, reflecting the issuance and sale on May 2, 2007 by Unitil Corporation of $20.0 million of 6.33% Senior Long-Term Notes, due May 1, 2022, to institutional investors in the form of a private placement. Short-term Debt decreased $13.0 million as of March 31, 2008 compared to March 31, 2007, as short-term borrowings were refinanced with the issuance of Senior Long-Term Notes, discussed above.

Electric Sales, Revenues and Margin

Kilowatt-hour Sales – In the first quarter of 2008, Unitil’s total electric kWh sales decreased 1.4% compared to the first quarter of 2007. Sales to residential and C&I customers decreased 0.9% and 1.7%, respectively, in the first quarter of 2008 compared to the same period in 2007. The lower kWh sales in 2008 compared to 2007 were primarily driven by lower average usage by our customers reflecting a slowing economy and energy conservation.

The following table details total kWh sales for the three months ended March 31, 2008 and 2007 by major customer class:


kWh Sales (millions)
	Three Months Ended March 31,

Total Electric Operating Revenues decreased by $6.1 million, or 9.7%, in the three months ended March 31, 2008 compared to the same period in 2007. Total Electric Operating Revenues include the recovery of costs of electric sales, which are recorded as Purchased Electricity and Conservation & Load Management (C&LM) in Operating Expenses. The decrease in Total Electric Operating Revenues in the three months ended March 31, 2008 reflects lower Purchased Electricity costs of $5.3 million, lower C&LM revenues of $0.4 million and lower sales margin of $0.4 million.

Purchased Electricity and C&LM revenues decreased a combined $5.7 million, or 9.1%, of Total Electric Operating Revenues in the three months ended March 31, 2008 compared to the same period in 2007, reflecting lower electric kWh sales, an increase in the amount of electricity purchased by customers directly from third-party suppliers and lower electric commodity prices. Purchased Electricity revenues include the recovery of the cost of electric supply as well as other energy supply related restructuring costs, including long-term power supply contract buyout costs. C&LM revenues include the recovery of the cost of energy efficiency and conservation programs. The Company recovers the cost of Purchased Electricity and C&LM in its rates at cost on a pass through basis.

Gas Sales, Revenues and Margin

Therm Sales – Therm sales of natural gas decreased 1.7% in the three months ended March 31, 2008 compared to the same period in 2007. Sales to residential customers and C&I customers decreased 2.0% and 1.4%, respectively, in the first quarter of 2008 compared to the same period in 2007. The decrease in gas sales in 2008 reflects a milder winter heating season this year and lower average usage by our customers reflecting a slowing economy and energy conservation.

The following table details total firm therm sales for the three months ended March 31, 2008 and 2007, by major customer class:


Therm Sales (millions)
	Three Months Ended March 31,

⁽¹⁾	Represents change as a percent of Total Gas Operating Revenue.

Total Gas Operating Revenues increased $0.1 million, or 0.7%, in the three months ended March 31, 2008 compared to the same period in 2007. Total Gas Operating Revenues include the recovery of the cost of sales, which are recorded as Purchased Gas and C&LM in Operating Expenses. The net increase in Total Gas Operating Revenues in three months ended March 31, 2008 reflects higher sales margin of $0.9 million, offset by lower Purchased Gas costs of $0.8 million.

Purchased Gas and C&LM revenues decreased a combined $0.8 million, or 5.6%, of Total Gas Operating Revenues in three months ended March 31, 2008 compared to the same period in 2007, primarily reflecting lower natural gas sales and an increase in the amount of natural gas purchased by customers directly from third-party suppliers. Purchased Gas revenues include the recovery of the cost of gas supply as well as the other energy supply related costs. C&LM revenues include the recovery of the cost of energy efficiency and conservation programs. The Company recovers the cost of Purchased Gas and C&LM in its rates at cost on a pass through basis.

Gas sales margin increased $0.9 million in the three months ended March 31, 2008 compared to the same period in 2007 reflecting higher gas base rates, implemented in 2007.

Operating Revenue - Other

The following table details total Other Operating Revenue for the three months ended March 31, 2008 and 2007:


Other Operating Revenue (Millions)
	Three Months Ended March 31,
	2008		2007		$ Change		% Change
Other	$	1.0	$	0.9	$	0.1	11.1	%

Total Other Operating Revenue	$	1.0	$	0.9	$	0.1	11.1	%

Total Other Operating Revenue increased $0.1 million, or 11.1%, in the three month period ended March 31, 2008 compared to the same period in 2007. The increase was the result of growth in revenues from the Company’s non-regulated energy brokering business, Usource.

Operating Expenses

Purchased Electricity – Purchased Electricity expenses include the cost of electric supply as well as the other energy supply related restructuring costs, including long-term power supply contract buyout costs. Purchased Electricity decreased $5.3 million, or 11.0%, in the three month period ended March 31, 2008 compared to the same period in 2007, reflecting lower electric kWh sales, an increase in the amount of electricity purchased by customers directly from third-party suppliers and lower electric commodity prices. The Company recovers the costs of Purchased Electricity in its rates at cost on a pass through basis and therefore changes in these expenses do not affect Net Income.

Purchased Gas – Purchased Gas expenses include the cost of gas purchased and manufactured to supply the Company’s total gas supply requirements. Purchased Gas decreased $0.8 million, or 8.2%, in the three month period ended March 31, 2008 compared to the same period in 2007, primarily reflecting lower natural gas sales and an increase in the amount of natural gas purchased by customers directly from third-party suppliers. The Company recovers the costs of Purchased Gas in its rates at cost on a pass through basis and therefore changes in these expenses do not affect Net Income.

Operation and Maintenance (O&M) - O&M expense includes electric and gas utility operating costs, and the operating cost of the Company’s unregulated business activities. Total O&M expenses decreased $1.8 million for the three month period ended March 31, 2008 compared to the same period in 2007. This decrease reflects a reduction to operating expenses of $2.8 million from the proceeds of an insurance settlement associated with environmental remediation costs. This reduction to operating expenses was partially offset by annual increases in salary, wage and benefit costs of $0.7 million, higher professional fees of $0.2 million and higher bad debt expenses of $0.1 million.

Conservation & Load Management – C&LM expenses are associated with the development, management, and delivery of the Company’s Energy Efficiency programs. Energy Efficiency programs are designed, in conformity with state regulatory requirements, to help consumers use electricity and natural gas more efficiently and thereby decrease their energy costs. Programs are tailored to residential, small business and large business customer groups and provide educational materials, technical assistance, and rebates that contribute toward the cost of purchasing and installing approved measures. Approximately 90% of these costs are related to electric operations and 10% to gas operations.

Total C&LM expenses decreased by $0.4 million, or 40.0%, in three month period ended March 31, 2008 compared to the same period in 2007. The decrease reflects the timing of spending on the implementation of Energy Efficiency programs. These costs are collected from customers on a pass through basis and therefore, fluctuations in program costs have no impact on Net Income.

Depreciation, Amortization and Taxes

Depreciation and Amortization - Depreciation and Amortization expense increased $0.7 million, or 15.6%, for the three month period ended March 31, 2008 compared to the same period in 2007. This increase primarily reflects the amortization of $0.7 million of natural gas inventory carrying costs deferred under a previous regulatory ruling.

Local Property and Other Taxes - Local Property and Other Taxes increased by $0.2 million, or 13.3% for the three month period ended March 31, 2008 compared to the same period in 2007. This increase was due to higher property tax rates on increased property assessments and higher payroll taxes on higher compensation expenses.

Federal and State Income Taxes - Federal and State Income Taxes were higher by $0.2 million for the three months ended March 31, 2008 compared to the same period in 2007 reflecting higher pre-tax earnings.

Other Non-Operating Expense

Other Non-Operating Expense increased by $0.1 million in the three month period ended March 31, 2008 compared to the same period in 2007. This increase reflects an adjustment of $0.1 million in conjunction with the Company’s recently approved electric base distribution rate increase in Massachusetts.

Interest Expense, Net

Interest expense is presented in the financial statements net of interest income. Interest expense is mainly comprised of interest on long-term debt and short-term borrowings. Certain reconciling rate mechanisms used by the Company’s distribution operating utilities give rise to regulatory assets (and regulatory liabilities) on which interest is calculated.

The Company operates a number of reconciling rate mechanisms to recover specifically identified costs on a pass through basis. These reconciling rate mechanisms track costs and revenue on a monthly basis. In any given month, this monthly tracking and reconciling process will produce either an under-collected or an over-collected balance of costs. In accordance with the Company’s tariff, interest is accrued on these balances and will produce either interest income or interest expense. Interest income is recorded on an under-collection of costs, which creates a regulatory asset to be recovered in future periods when rates are reset. Interest expense is recorded on an over-collection of costs, which creates a regulatory liability to be refunded in future periods when rates are reset.

Subtotal Interest Income		(0.5	)		(0.9	)		0.4

Total Interest Expense, Net	$	2.6		$	2.1		$	0.5

Interest Expense, Net increased by $0.5 million in the three month period ended March 31, 2008 compared to the same period in 2007. Interest expense on long-term borrowings increased due to the issuance of new long-term

debt by Unitil on May 2, 2007. Unitil issued and sold $20 million of Senior Long-Term Notes at a coupon rate of 6.33%, through a private placement to institutional investors. The Company utilized the proceeds from the long-term Note financing to refinance existing short-term debt and for other corporate purposes of the Company’s principal utility subsidiaries. The resulting reduction in average daily short-term bank borrowings lowered short-term interest expense for the first quarter of 2008 compared to the same period in 2007. An adjustment of $0.2 million related to earnings on funds used for capital projects ordered in conjunction with the Company’s recently approved electric base distribution rate increase in Massachusetts and lower carrying charges earned on regulatory assets also contributed to the increase in Interest Expense, Net.

CAPITAL REQUIREMENTS

Sources of Capital

Unitil requires capital to fund utility plant additions, working capital and other utility expenditures recovered in subsequent and future periods through regulated rates. The capital necessary to meet these requirements is derived primarily from internally-generated funds, which consist of cash flows from operating activities, excluding payment of dividends. The Company initially supplements internally generated funds through bank borrowings, as needed, under unsecured short-term bank lines. The Company had short-term debt outstanding through bank borrowings of $16.7 and $29.7 at March 31, 2008 and March 31, 2007, respectively. In addition, Unitil had approximately $4.0 million in cash at March 31, 2008. Periodically, the Company replaces portions of its short-term debt with long-term financings more closely matched to the long-term nature of its utility assets.

The continued availability of these methods of financing, as well as the Company’s choice of a specific form of security, will depend on many factors, including, but not limited to: security market conditions; general economic climate; regulatory approvals; the ability to meet covenant issuance restrictions, if any; the level of the Company’s earnings, cash flows and financial position; and the competitive pricing offered by financing sources.

On February 15, 2008, the Company entered into a Stock Purchase Agreement with NiSource and Bay State to acquire all of the outstanding stock of Northern Utilities, Inc. and Granite State Gas Transmission, Inc. The Company has entered into a senior unsecured bridge facility, which is available to finance this transaction. The Company anticipates either financing the initial acquisition or refinancing the bridge facility with the issuance of a combination of unsecured senior notes and common/or preferred equity securities.

The Company provides limited guarantees on certain energy contracts entered into by its regulated subsidiary companies. The Company’s policy is to limit these guarantees to the duration of the contracts, which range from less than one month to two and one-half years. As of March 31, 2008, there were approximately $6.0 million of guarantees outstanding and the longest term guarantee extends through October 31, 2009.

The tables below summarize the major sources and uses of cash (in millions) for the three months ended March 31, 2008, compared to the same period in 2007.


Cash Provided by Operating Activities	$	7.9	$	6.1

Cash Provided by Operating Activities - Cash Provided by Operating Activities was $7.9 million during the first three months ended March 31, 2008, an increase of $1.8 million over the comparable period in 2007. Cash flow from Net Income, adjusted for non-cash charges to depreciation, amortization and deferred taxes of $1.0 million, was $1.7 million higher in the first three months of 2008 compared to 2007. Working Capital related cash flows increased by $0.6 million during the first three months of 2008 compared to the same period in 2007. Deferred Restructuring Charges were a $1.0 million source of cash in the first quarter of 2008 compared to the same period in 2007. These charges were deferred in prior periods for collection current rates. All other changes in operating activities were a net $1.5 million in uses of cash in the first three months of 2008 compared to 2007, including a $2.8 million source of cash from the insurance settlement discussed above.


Cash (Used in) Investing Activities	$	(4.5	)	$	(9.6	)

Cash (Used in) Investing Activities - Cash (Used in) Investing Activities was $4.5 million for the three months ended March 31, 2008 reflecting a source of cash due to a decrease in capital spending of $5.1 million over the comparable period in 2007 mainly due to the completion of the Company’s Advanced Metering Infrastructure (“AMI”) project. In the first quarter 2007, capital expenditures included approximately $2.8 million of cash outlays for investment in the AMI project. Capital expenditure projections are subject to changes during the fiscal year.


Cash Provided by (Used in) Financing Activities	$	(4.0	)	$	1.7

Cash Provided by (Used in) Financing Activities - Cash Used in Financing Activities was $4.0 million in the three months ended March 31, 2008, a decrease of $5.7 million over the comparable period in 2007. Cash provided from short-term debt declined by $5.8 million in the first quarter of 2008, principally reflecting the repayment of short-term debt from the proceeds of an insurance settlement. All other cash flows provided from other financing activities aggregated to a net $0.1 million increase in the first three months of 2008 as compared to the same period in 2007.

CRITICAL ACCOUNTING POLICIES

The preparation of the Company’s financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In making those estimates and assumptions, management is sometimes required to make difficult, subjective and/or complex judgments about the impact of matters that are inherently uncertain and for which different estimates that could reasonably have been used could have resulted in material differences in its financial statements. If actual results were to differ significantly from those estimates, assumptions and judgments, the financial statements of the Company could be materially different than reported. The following is a summary of the Company’s most critical accounting policies, which are defined as those policies where judgments or uncertainties could materially affect the application of those policies. For a complete discussion of the Company’s significant accounting policies, refer to the Note 1 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on February 12, 2008.

Regulatory Accounting - The Company’s principal business is the distribution of electricity and natural gas by the retail distribution companies: UES and FG&E. Both UES and FG&E are subject to regulation by the FERC and FG&E is regulated by the MDPU and UES is regulated by the NHPUC. Accordingly, the Company uses the provisions of FASB Statement No. 71, “Accounting for the Effects of Certain Types of Regulation.” (SFAS No. 71). In accordance with SFAS No. 71, the Company has recorded Regulatory Assets and Regulatory Liabilities which will be recovered from customers, or applied for customer benefit, in accordance with rate provisions approved by the applicable public utility regulatory commission.

The Company’s principal regulatory assets and liabilities are detailed on the Company’s Consolidated Balance Sheet and a summary of the Company’s Regulatory Assets is provided below. The Company receives a return on investment on its regulated assets for which a cash outflow has been made.

Regulatory commissions can reach different conclusions about the recovery of costs, which can have a material impact on the Company’s consolidated financial statements. The Company believes it is probable that its regulated utility companies will recover their investments in long-lived assets, including regulatory assets. The Company also has commitments under long-term contracts for the purchase of electricity and natural gas from various suppliers. The annual costs under these contracts are included in Purchased Electricity and Purchased Gas in the Consolidated Statements of Earnings and these costs are recoverable in current and future rates under various orders issued by the FERC, MDPU and NHPUC.


Regulatory Assets consist of the following (millions)
	March 31,				December 31,
	2008		2007		2007
Power Supply Buyout Obligations	$	67.7	$	87.6	$	72.7
Deferred Restructuring Costs		29.6		30.9		30.5
Generation-related Assets		1.4		2.1		1.6

Subtotal – Restructuring Related Items		98.7		120.6		104.8

Retirement Benefit Obligations		35.1		37.1		35.1
Income Taxes		14.2		18.7		14.6
Environmental Obligations		13.3		13.0		13.1
Other		3.0		3.9		2.9

Total Regulatory Assets	$	164.3	$	193.3	$	170.5

If the Company, or a portion of its assets or operations, were to cease meeting the criteria for application of these accounting rules, accounting standards for businesses in general would become applicable and immediate recognition of any previously deferred costs, or a portion of deferred costs, would be required in the year in which the criteria are no longer met, if such deferred costs were not recoverable in the portion of the business that continues to meet the criteria for application of SFAS No. 71. If unable to continue to apply the provisions of SFAS No. 71, the Company would be required to apply the provisions of FASB Statement No. 101, “Regulated Enterprises – Accounting for the Discontinuation of Application of Financial Accounting Standards Board Statement No. 71.” In the Company’s opinion, its regulated operations will be subject to SFAS No. 71 for the foreseeable future.

Utility Revenue Recognition - Regulated utility revenues are based on rates and charges approved by federal and state regulatory commissions. Revenues related to the sale of electric and gas service are recorded when service is rendered or energy is delivered to customers. The determination of energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each calendar month, amounts of energy delivered to customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is estimated. This unbilled revenue is estimated each month based on estimated customer usage by class and applicable customer rates.

Allowance for Doubtful Accounts - The Company recognizes a Provision for Doubtful Accounts each month. The amount of the monthly Provision is based upon the Company’s experience in collecting electric and gas utility service accounts receivable in prior years. Account write-offs, net of recoveries, are processed monthly. At the end of each month, an analysis of the delinquent receivables is performed and the adequacy of the Allowance for Doubtful Accounts is reviewed. The analysis takes into account an assumption about the cash recovery of delinquent receivables and also uses calculations related to customers who have chosen payment plans to resolve their arrears. The analysis also calculates the amount of written-off receivables that are recoverable through regulatory rate reconciling mechanisms. The Company is authorized by regulators to recover the supply-related portion of its written-off accounts from customers through periodically reconciling rate mechanisms. Evaluating the adequacy of the Allowance for Doubtful Accounts requires judgment about the assumptions used in the analysis, including expected fuel assistance payments from governmental authorities and the level of customers enrolling in payment plans with the Company. Also, the Company has experienced periods when state regulators have extended the periods during which certain standard credit and collection activities of utility companies are suspended. In periods when account write-offs exceed estimated levels, the Company adjusts the Provision for Doubtful Accounts to maintain an adequate Allowance for Doubtful Accounts balance. It has been the Company’s experience that the assumptions it has used in evaluating the adequacy of the Allowance for Doubtful Accounts have proven to be reasonably accurate.

Retirement Benefit Obligations - The Company sponsors the Unitil Corporation Retirement Plan (Pension Plan), which is a defined benefit pension plan covering substantially all of its employees. The Company also sponsors an unfunded retirement plan, the Unitil Corporation Supplemental Executive Retirement Plan (SERP), covering certain executives of the Company and an employee 401(k) savings plan. Additionally, the Company

sponsors the Unitil Employee Health and Welfare Benefits Plan (PBOP Plan), primarily to provide health care and life insurance benefits to retired employees.

In September 2006, the FASB issued FASB Statement No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans”, (SFAS No. 158), an amendment of SFAS No. 87, “Employers’ Accounting for Pensions”, SFAS No. 88, “Employers’ Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits,” SFAS No. 106, “Employers’ Accounting for Postretirement Benefits other than Pensions” and SFAS No. 132(R), “Employers’ Disclosures about Pensions and Other Postretirement Benefits.” SFAS No. 158 requires companies to record on their balance sheets as an asset or liability the overfunded or underfunded status of their retirement benefit obligations (RBO) based on the projected benefit obligation. The Company has recognized a corresponding Regulatory Asset, to recognize the future collection of these obligations in electric and gas retail rates.

The Company’s reported costs of providing retirement benefits are dependent upon numerous factors resulting from actual plan experience and assumptions of future experience. The Company has made critical estimates related to actuarial assumptions, including assumptions of expected returns on plan assets, future compensation, health care cost trends, and appropriate discount rates. The Company’s health care cost trend assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. The Company’s RBO are affected by actual employee demographics, the level of contributions made to the plans, earnings on plan assets, and health care cost trends. Changes made to the provisions of these plans may also affect current and future costs. The Company’s RBO may also be significantly affected by changes in key actuarial assumptions, including, anticipated rates of return on plan assets and the discount rates used in determining the Company’s RBO.

If these assumptions were changed, the resultant change in benefit obligations, fair values of plan assets, funded status and net periodic benefit costs could have a material impact on the Company’s financial statements. The discount rate assumptions used in determining retirement plan costs and retirement plan obligations are based on a market average of long-term bonds that receive one of the two highest ratings given by a recognized rating agency. For the years ended December 31, 2007 and 2006, a change in the discount rate of 0.25% would have resulted in an increase or decrease of approximately $200,000 in the Net Periodic Benefit Cost for the Pension Plan. For the years ended December 31, 2007 and 2006, a 1.0% increase in the assumption of health care cost trend rates would have resulted in increases in the Net Periodic Benefit Cost for the PBOP Plan of $690,000 and $683,000, respectively. Similarly, a 1.0% decrease in the assumption of health care cost trend rates for those same time periods would have resulted in decreases in the Net Periodic Benefit Cost for the PBOP Plan of $539,000 and $530,000, respectively. (See Note 8)

Income Taxes - Provisions for income taxes are calculated in each of the jurisdictions in which the Company operates for each period for which a statement of income is presented. This process involves estimating the Company’s current tax liabilities as well as assessing temporary and permanent differences resulting from the timing of the deductions of expenses and recognition of taxable income for tax and book accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included in the Company’s consolidated balance sheets. The Company accounts for income tax assets, liabilities and expenses in accordance with FASB Statement No. 109, “Accounting for Income Taxes” (SFAS No. 109) and under FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48), an interpretation of FAS 109.

Depreciation - Depreciation expense is calculated on a group straight-line basis based on the useful lives of assets and judgment is involved when estimating the useful lives of certain assets. The Company conducts independent depreciation studies on a periodic basis as part of the regulatory ratemaking process and considers the results presented in these studies in determining the useful lives of the Company’s fixed assets. A change in the estimated useful lives of these assets could have a material impact on the Company’s consolidated financial statements.

Commitments and Contingencies - The Company’s accounting policy is to record and/or disclose commitments and contingencies in accordance with SFAS No. 5. SFAS No. 5 applies to an existing condition, situation, or set of circumstances involving uncertainty as to possible loss that will ultimately be resolved when one or more future events occur or fail to occur. As of March 31, 2008, the Company is not aware of any material commitments or contingencies other than those disclosed in the Commitments and Contingencies footnote to the Company’s consolidated financial statements below.

Refer to “Recently Issued Accounting Pronouncements in Note 1 of the Notes of Consolidated Financial Statements for information regarding recently issued accounting standards.

LABOR RELATIONS

There are approximately 100 employees of the Company represented by labor unions. In May 2005, the Company reached agreements with its bargaining units for new five-year contracts, effective June 1, 2005. These agreements replace contracts that expired on May 31, 2005.

INTEREST RATE RISK

The majority of the Company’s debt outstanding represents long-term notes bearing fixed rates of interest. Changes in market interest rates do not affect interest expense resulting from these outstanding long-term debt securities. However, the Company periodically repays its short-term debt borrowings through the issuance of new long-term debt securities. Changes in market interest rates may affect the interest rate and corresponding interest expense on any new long-term debt securities issued by the Company. In addition, the Company’s short-term debt borrowings bear a variable rate of interest. As a result, changes in short-term interest rates will increase or decrease the Company’s interest expense in future periods. For example, if the Company had an average amount of short-term debt outstanding of $25 million for the period of one year, a change in interest rates of 1% would result in a change in annual interest expense of approximately $250,000 (pre-tax). The average interest rates on the Company’s short-term borrowings for the three months ended March 31, 2008 and March 31, 2007 were 3.84% and 5.77%, respectively.

MARKET RISK

Although Unitil’s utility operating companies are subject to commodity price risk as part of their traditional operations, the current regulatory framework within which these companies operate allows for full collection of electric power and natural gas supply costs in rates on a pass-through basis. Consequently, there is limited commodity price risk after consideration of the related rate-making. Additionally, as discussed above and below in Regulatory Matters, the Company has divested its commodity-related contracts and therefore, further reduced its exposure to commodity risk.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation – The accompanying unaudited consolidated financial statements of Unitil have been prepared in accordance with the instructions to Form 10-Q and include all of the information and footnotes required by generally accepted accounting principles. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. The results of operations for the three months ended March 31, 2008 are not necessarily indicative of results to be expected for the year ending December 31, 2008. For further information, please refer to Note 1 of Part II to the Consolidated Financial Statements – “Summary of Significant Accounting Policies” of the Company’s Form 10-K for the year ended December 31, 2007, as filed with the SEC on February 12, 2008, for a description of the Company’s Basis of Presentation.

Nature of Operations – Unitil Corporation (Unitil or the Company) is a public utility holding company. Unitil and its subsidiaries are subject to regulation as a holding company system by the Federal Energy Regulatory Commission (FERC) under the Energy Policy Act of 2005. Prior to the passage of the Energy Policy Act of 2005, Unitil and its subsidiaries were subject to regulation as a registered holding company system under the Public Utility Holding Company Act of 1935 (PUHCA) by the Securities and Exchange Commission (SEC). As a result of the enactment of the Energy Policy Act of 2005, PUHCA has been repealed. The following companies are wholly-owned subsidiaries of Unitil: Unitil Energy Systems, Inc. (UES), Fitchburg Gas and Electric Light Company (FG&E), Unitil Power Corp. (Unitil Power), Unitil Realty Corp. (Unitil Realty), Unitil Service Corp. (Unitil Service) and its non-regulated business unit Unitil Resources, Inc. (Unitil Resources). Usource, Inc. and Usource L.L.C. are subsidiaries of Unitil Resources.

Unitil’s principal business is the retail distribution of electricity in the southeastern seacoast and capital city areas of New Hampshire and the retail distribution of both electricity and natural gas in the greater Fitchburg area of north central Massachusetts, through the Company’s two wholly-owned subsidiaries, UES and FG&E, collectively referred to as the retail distribution utilities.

A third utility subsidiary, Unitil Power, formerly functioned as the full requirements wholesale power supply provider for UES. In connection with the implementation of electric industry restructuring in New Hampshire, Unitil Power ceased being the wholesale supplier of UES on May 1, 2003 and divested of its long-term power supply contracts through the sale of the entitlements to the electricity associated with various electric power supply contracts it had acquired to serve UES’ customers.

Unitil also has three other wholly-owned subsidiaries: Unitil Service, Unitil Realty and Unitil Resources. Unitil Service provides, at cost, a variety of administrative and professional services, including regulatory, financial, accounting, human resources, engineering, operations, technology and management services on a centralized basis to its affiliated Unitil companies. Unitil Realty owns and manages the Company’s corporate office in Hampton, New Hampshire and leases this facility to Unitil Service under a long-term lease arrangement. Unitil Resources is the Company’s wholly-owned non-regulated subsidiary. Usource, Inc. and Usource L.L.C. (collectively, Usource) are wholly-owned subsidiaries of Unitil Resources. Usource provides brokering and advisory services to large commercial and industrial customers in the northeastern United States.

Recently Issued Pronouncements – In March 2008, the FASB issued FASB Statement No. 161, “Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133” (SFAS No. 161) , effective for fiscal years and interim periods beginning after November 15, 2008, with early adoption allowed. SFAS No. 161 amends and expands the disclosure requirements of SFAS No. 133 with the intent to provide users of financial statements with an enhanced understanding of an entity’s use of derivative instruments and the effect of those derivative instruments on an entity’s financial statements. The Company adopted SFAS No. 161 and there was no impact on its financial statements.

In December 2007, the FASB issued FASB Statement No. 141 (Revised 2007), “Business Combinations” (SFAS No. 141R), effective prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. SFAS No. 141R establishes principles and requirements on how an acquirer recognizes and measures in its financial statements identifiable assets acquired, liabilities assumed, noncontrolling interests in the acquiree, goodwill or gain from a bargain purchase and accounting for transaction costs. Additionally, SFAS No. 141R determines what information must be disclosed to enable users of the financial statements to evaluate the nature and financial effects of the business combination. The Company will adopt SFAS No. 141R upon its effective date and expects the adoption to affect any business combinations effected on or subsequent to that date.

In September 2006, the FASB issued FASB Statement No. 157, “Fair Value Measurements”, (SFAS No. 157). SFAS No. 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Certain requirements of SFAS No. 157 are effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The effective date for other requirements of SFAS No. 157 has been deferred for one year by the FASB. The Company adopted the sections of SFAS No. 157 which are effective for fiscal years beginning after November 15, 2007 and there was no additional impact on the Company’s Consolidated Financial Statements. The Company’s fixed rate long-term debt falls under the fair value reporting requirements of SFAS No. 157. Accordingly, the Company has estimated the fair value of its long-term debt as of March 31, 2008 based on the quoted market prices for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities (See Note 4). The Company does not expect that the adoption of the deferred sections of SFAS No. 157 will have an impact on the Company’s Consolidated Financial Statements.

The Company maintains a Restricted Stock Plan (the Plan) which has been ratified and approved by the Company’s shareholders. On February 6, 2008, 15,540 restricted shares were issued in conjunction with the Plan with an aggregate market value at the date of issuance of $445,998. Compensation expense associated with shares issued under the Plan is recognized ratably as the shares vest and was $0.1 million and $0.1 million for three months ended March 31, 2008 and 2007, respectively. At March 31, 2008, there was approximately $1.1 million of total unrecognized compensation cost related to non-vested shares under the Plan which is expected to be recognized over approximately 2.9 years as the shares vest.

The fair value of the Company’s long-term debt is estimated based on the quoted market prices for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the Company’s long-term debt at March 31, 2008 is estimated to be approximately $166 million, before considering any costs, including prepayment costs, to market the Company’s debt. Currently, the Company believes that there is no active market in the Company’s debt securities, which have all been sold through private placements.

The Company provides limited guarantees on certain energy contracts entered into by its regulated subsidiary companies. The Company’s policy is to limit these guarantees to two years or less. As of March 31, 2008 there are $6 million of guarantees outstanding and these guarantees extend through October 31, 2009. These guarantees are not required to be recorded under the provisions of FASB Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.”

NOTE 6 – REGULATORY MATTERS

UNITIL’S REGULATORY MATTERS ARE DESCRIBED IN NOTE 5 TO THE FINANCIAL STATEMENTS IN ITEM 8 OF PART II OF UNITIL CORPORATION’S FORM 10-K FOR DECEMBER 31, 2007 AS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION ON FEBRUARY 12, 2008.

FG&E – Electric Division – On December 3, 2007, FG&E submitted its annual reconciliation of costs and revenues for Transition, Transmission, Standard Offer Service, and Default Service filed under its restructuring plan (the Annual Reconciliation Filing). The rates were approved effective January 1, 2008, subject to reconciliation pursuant to the MDPU’s investigation. This matter remains pending.

On August 17, 2007, FG&E filed an electric distribution rate increase of $3.3 million, which represented an increase of 4.7 percent over FG&E’s 2006 total electric operating revenue. Evidentiary hearings were held in November 2007 and briefing was completed in January 2008. On February 29, 2008, the Company received a final order from the MDPU approving an electric distribution rate increase of $2.1 million, which represents an increase of 3.0 percent over FG&E’s 2006 total electric operating revenue. The order also provides for recovery

of approximately $0.1 million annually of supply-related operating and administrative costs through default service rates. The new electric rates were effective as of March 1, 2008.

FG&E – Other – On June 22, 2007, the MDPU opened an inquiry into revenue decoupling, generally defined as a ratemaking mechanism designed to eliminate or reduce the dependence of a utility’s distribution revenues on sales. Revenue decoupling is intended to remove the disincentive a utility has to administer and promote customer efforts to reduce energy consumption and demand or to install distributed generation to displace electricity delivered by the utility. This matter remains pending.

UES – On March 14, 2008, UES made its annual reconciliation and rate filing with the NHPUC under its restructuring plan, effective May 1, 2008, including reconciliation of prior year costs and revenues, power supply and power supply-related stranded costs. The filing is pending, subject to investigation. A hearing is scheduled for April 22, 2008.

On June 22, 2007, the NHPUC issued an order in its investigation into implementation of the federal Energy Policy Act of 2005 regarding the adoption of standards for time-based metering and interconnection. On August 31, 2007, the NHPUC issued an order on motion for rehearing, staying the June 22, 2007 order pending hearing and reconsideration of the issues. An order following rehearing was issued on January 22, 2008 finding that it is appropriate to implement time-based metering standards and ordering that the details, including cost-benefit analyses, form of rate design, time of implementation and applicable customer classes shall be determined in separate proceedings to be initiated by the Commission.

On May 14, 2007, the NHPUC issued an order opening an investigation into the merits of instituting appropriate rate mechanisms, such as revenue decoupling, which would have the effect of removing obstacles to, and encouraging investment in, energy efficiency. On March 13, 2008, the NHPUC issued a letter seeking written comments regarding the utilities experience with declining sales attributable to energy conservation, energy efficiency, and demand response and whether existing rate treatment poses an obstacle to investment in energy efficiency. Comments are due April 11, 2008.

Unitil Corp. – On February 15, 2008, Unitil reached agreement with NiSource Inc. and Bay State Gas Company to purchase 100 percent of the ownership shares of Northern Utilities, Inc. and Granite State Gas Transmission, Inc. for $160 million plus a net working capital adjustment. The Company has entered into a senior unsecured bridge facility, which is available to finance this transaction. The Company anticipates either financing the initial acquisition or refinancing the bridge facility with the issuance of a combination of unsecured senior notes and common/or preferred equity securities. On March 31, 2008, Unitil filed petitions and testimony with both the Maine Public Utilities Commission and the New Hampshire Public Utilities Commission requesting approval of the acquisitions. As of March 31, 2008, the Company has capitalized $1.1 million of transaction costs associated with the acquisition. The transaction is expected to close by the fourth quarter of 2008, subject to approval by these commissions and review by certain federal agencies.

NOTE 7 – ENVIRONMENTAL MATTERS

UNITIL’S ENVIRONMENTAL MATTERS ARE DESCRIBED IN NOTE 5 TO THE FINANCIAL STATEMENTS IN ITEM 8 OF PART II OF UNITIL CORPORATION’S FORM 10-K FOR DECEMBER 31, 2007 AS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION ON FEBRUARY 12, 2008.

The Company’s past and present operations include activities that are generally subject to extensive federal and state environmental laws and regulations. The Company believes it is in compliance with all applicable environmental and safety laws and regulations, and the Company believes that as of March 31, 2008, there are no material losses reasonably possible in excess of recorded amounts. However, there can be no assurance that significant costs and liabilities will not be incurred in the future. It is possible that other developments, such as increasingly stringent federal, state or local environmental laws and regulations could result in increased environmental compliance costs.

Included on the Company’s Consolidated Balance Sheet at March 31, 2008, in Environmental Obligations is $12.0 million related to estimated future clean up costs for permanent remediation of a former manufactured gas plant site at Sawyer Passway, located in Fitchburg, Massachusetts. A corresponding regulatory asset was

recorded to reflect the future rate recovery of these costs. As noted above, please refer to Note 5 to the financial statements in Item 8 of Part II of the Company’s Form 10-K for December 31, 2007 for additional information. As discussed above, the Company received an insurance settlement during the first quarter of 2008. Any recovery that FG&E receives from insurance or third parties with respect to environmental response costs, net of the unrecovered costs associated therewith, are split equally between FG&E and its gas customers.

NOTE 8: RETIREMENT BENEFIT OBLIGATIONS

The Company sponsors the following retirement benefit plans to provide certain pension and postretirement benefits for its retirees and current employees as follows:

•

The Unitil Corporation Retirement Plan (Pension Plan) – The Pension Plan is a defined benefit pension plan covering substantially all of its employees. Under the Pension Plan, retirement benefits are based upon an employee’s level of compensation and length of service.

•

The Unitil Retiree Health and Welfare Benefits Plan (PBOP Plan) – The PBOP Plan provides health care and life insurance benefits to retirees. The Company has established Voluntary Employee Benefit Trusts (VEBT), into which it funds contributions to the PBOP Plan.

•

The Unitil Corporation Supplemental Executive Retirement Plan (SERP) – The SERP is an unfunded retirement plan, with participation limited to executives selected by the Board of Directors.

The following table includes the key weighted average assumptions used in determining the Company’s benefit plan costs and obligations:


	2008		2007
Used to Determine Plan Costs

Employer Contributions

On August 17, 2006, the Pension Protection Act of 2006 (PPA) was signed into law. Included in the PPA are new minimum funding rules which will go into effect for plan years beginning in 2008. The funding target will be 100% of a plan’s liability with any shortfall amortized over seven years, with lower (92% – 100%) funding targets available to well-funded plans during the transition period. The Company expects to contribute approximately $2.8 million to fund its Pension Plan in 2008.

As of March 31, 2008, the Company had made $0.5 million and $18,000 of contributions to the PBOP and SERP Plans, respectively, in 2008. The Company presently anticipates contributing an additional $2.0 million and $54,000 to the PBOP and SERP Plans, respectively, in 2008.

NOTE 9: INCOME TAXES

The Company bills its customers sales tax in Massachusetts and consumption tax in New Hampshire. These taxes are remitted to the appropriate departments of revenue in each state and are excluded from revenues on the Company’s Consolidated Statements of Earnings.

The Company evaluated its tax positions at December 31, 2007 and for the current interim reporting period ended March 31, 2008 in accordance with FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48), an interpretation of FAS 109, and has concluded that no adjustment for recognition, derecognition, settlement and foreseeable future events to any unrecognized tax liabilities or assets as defined by FIN 48 is required. The Company does not have any unrecognized tax positions for which it is reasonably possible that the total amounts recognized will significantly change within the next 12 months. The Company remains subject to examination by Federal, Massachusetts and New Hampshire tax authorities for the tax periods ended December 31, 2004; December 31, 2005; and December 31, 2006. Income tax filings for the year ended December 31, 2007 have been extended and are due September 15, 2008. The Company classifies penalty and interest expense related to income tax liabilities as an income tax expense. There are no interest and penalties recognized in the statement of earnings or accrued on the balance sheets.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

Reference is made to the “Interest Rate Risk” and “Market Risk” sections of Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (above).

Item 4.

Controls and Procedures

As of the end of the quarter covered by this Form 10-Q, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, the Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company required to be included in the Company’s periodic SEC filings.

There have been no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during the fiscal quarter covered by this Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1.

Legal Proceedings

The Company is involved in legal and administrative proceedings and claims of various types, which arise in the ordinary course of business. Certain specific matters are discussed in Notes 6 and 7 to the Consolidated Financial Statements. In the opinion of Management, based upon information furnished by counsel and others, the ultimate resolution of these claims will not have a material impact on the Company’s financial position.

Item 1A.

Risk Factors

There have been no material changes to the risk factors disclosed in the Company’s Form 10-K for the year-ended December 31, 2007 as filed with the Securities and Exchange Commission on February 12, 2008, other than the risks associated with the Company’s recently announced acquisition of Northern and Granite, as discussed in the Cautionary Statement section of Part I, Item 2 of this Quarterly Report on Form 10-Q for the quarter ended March 31, 2008.

Item 2.

Unregistered Sales of Equity Securities and Use of Proceeds

There were no sales of unregistered equity securities by the Company for the fiscal period ended March 31, 2008.

Pursuant to the written trading plan under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), adopted by the Company on March 20, 2008, the Company periodically repurchases shares of its Common Stock on the open market related to Employee Length of Service Awards and the stock portion of the Directors’ annual retainer. The Company may suspend or terminate its Rule 10b5-1 trading plan at any time, so long as the suspension or termination is made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Exchange Act, or other applicable securities laws. There is no pool or maximum number of shares related to these purchases. There were no Company repurchases during the three months ended March 31, 2008.
