Hampton, NH - May 1, 2002: Unitil Corporation (AMEX: UTL) (www.unitil.com) announced today that earnings per share were $0.36 for the first quarter, a decrease of $0.05 per share compared to the same three-month period last year. Utility Operations contributed $0.39 per share to consolidated results; a decline of $0.13 from last year, while Usource lost $0.03 per share, an improvement of $0.08 from the same period in 2001. The warmest winter on record in New England adversely affected gas and electricity sales in the Company's utility service territories in Massachusetts and New Hampshire. Gas sales were down almost 20% from prior year and electricity sales were off almost 4% compared to last winter.

"Notwithstanding the impact of weather, we remain focused on the things we do control such as operating costs and improving service and performance," said Bob Schoenberger, Chairman and CEO of Unitil. "By next year we intend to complete regulatory restructuring in New Hampshire, to revise distribution prices for all of our distribution businesses to reflect increased costs and to make Usource, our energy brokerage service, a profitable business."

Earnings per share for the 12 months ending March 31, 2002, after the charges discussed below, were $0.12, compared to $1.33 for the prior year. In the third quarter 2001, the Company recorded a one-time non-cash adjustment to Regulatory Assets of $5.3 million, resulting in an extraordinary charge of $3.9 million, net of taxes, to implement Massachusetts Department of Telecommunications and Energy orders on electric industry restructuring. In the fourth quarter of 2001, the Company recorded a non-cash charge of $3.7 million, $2.4 million net of tax, to recognize a decrease in the fair value of its non-utility investment in Enermetrix, Inc., an energy technology start-up enterprise.
