Staff providing services under the activities listed below (unless otherwise indicated) are located at Unitil Service Corp. (Unitil Service), 6 Liberty Lane West, Hampton, NH 03842-1720, where most client work is performed. From time to time staff visit other locations, predominately in New England, representing client interests.

Unitil Resources Inc. is Unitil Corporation's wholly-owned non-utility subsidiary and has been authorized by the Securities and Exchange Commission, pursuant to the rules and regulations of the 1935 Act, to engage in business transactions as a competitive marketer of electricity, gas and other energy commodities in wholesale and retail markets, and to provide energy brokering, consulting and management related services within the United States.

In April 2000, Unitil formed Usource, Inc. and Usource L.L.C. , collectively "Usource", to operate its Internet-based brokering and related energy products and services businesses. Usource, Inc. is a wholly owned subsidiary of Unitil Resources, Inc. and an indirect subsidiary of Unitil Corporation. Usource, Inc. is the sole member of Usource L.L.C.

Usource is an Internet-based energy marketplace that provides customers access to a customer-driven auction process for energy commodities and to a suite of value-added energy products, services and tools. Usource runs on the transactional-based software and energy commodity exchange developed and licensed from Enermetrix.com (The "Exchange") to assist customers with their energy procurement process and to ensure competitive, time-sensitive bids from energy suppliers. Usource acts as a broker, not an energy supplier. The Exchange provides energy suppliers with an Internet-based energy marketplace to offer energy consumers products and services. Usource will also provide data and information services to commercial and industrial customers desiring to control their energy procurement process and manage their energy usage.

The Federal Communications Commission has determined that Usource, Inc. and Usource LLC are exempt telecommunications companies, as that term is defined in PUHCA Section 34(a)(1), as amended. Accordingly, financial information for Usource, Inc. and Usource LLC is not included in the financial statements that follow.
