Item 8.01 Other Events

On March 26, 2009, the Company adopted a written trading plan under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to facilitate the repurchase of shares of its common stock in connection with its Board of Director Retainer Fees and Employee Length of Service Awards.

The Company's Rule 10b5-1 trading plan provides that a broker selected by Unitil has the authority to repurchase shares of the Company's common stock on the open market pursuant to the terms and limitations specified in the plan, including compliance with Rule 10b-18 under the Exchange Act. There can be no assurance that any shares will be repurchased by Unitil either through its Rule 10b5-1 trading plan or otherwise.

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.
