Energy Brokering and Consulting Services:

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 Public Utility Holding Company Act of 1935 (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 brokering and related energy products and services businesses. Usource, Inc. is a wholly–owned subsidiary of Unitil Resources, Inc. and is the sole member of Usource L.L.C.

Usource provides customers access to an electronically–supported bidding process for energy commodities and to a suite of value–added energy products, services and tools. Usource acts as a broker, not an energy supplier. Usource also provides 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 L.L.C. 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 L.L.C. is not included in the financial statements that follow.
