the Board of Directors. We may pay dividends on our common stock from any funds, property or shares legally available for such purpose. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><U>Voting Rights

Holders of common stock have the exclusive right to vote for the election of directors and for any other purpose or any other subject and to be represented at and to receive notice of any meeting of shareholders. Holders of our common stock do not
have cumulative voting rights. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><U>Board of Directors Classification </U></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our Board of Directors is divided into three classes, each class to be as nearly equal in number as possible as determined by the Board of
Directors, with a minimum of nine directors total, and maximum of 15 directors total. The terms of the directors in each class will expire in successive years. Directors are elected by ballot for a term of three years. Vacancies on our Board of
Directors may be filled by the affirmative vote of a majority of the remaining directors, though less than a quorum of the Board of Directors. A director elected to fill a vacancy is elected for the unexpired term of his predecessor in office. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><U>Provisions of Our Articles of Incorporation and <FONT STYLE="white-space:nowrap">By-Laws</FONT> That Could
Delay, Defer or Prevent a Change in Control </U></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Certain provisions in our Articles of Incorporation and
<FONT STYLE="white-space:nowrap">By-Laws</FONT> may delay, defer or make more difficult unsolicited acquisitions or changes of control of Unitil Corporation (&#147;Unitil&#148;). We believe that such provisions will enable us to develop our business
in a manner that will foster our long-term growth without disruption caused by the threat of a takeover not deemed by our Board of Directors to be in the best interest of Unitil and our shareholders. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The provision in our Articles of Incorporation relating to classification of the Board of Directors could have the effect of making it
difficult and time-consuming to change majority control of the Board of Directors. Such a change in control could take up to two annual meetings of shareholders to effect. As a result, this provision could limit the vulnerability of Unitil to an
unsolicited proposal to acquire Unitil or its assets. Takeovers which are proposed and effected without prior consultation and negotiation with management are not necessarily detrimental to a company and its shareholders. The difficulties, if any,
which may exist in effecting a change in control of Unitil&#146;s Board of Directors could benefit Unitil by protecting the Board of Directors&#146; ability to negotiate with the proponent of an unfriendly or unsolicited takeover proposal. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our Articles of Incorporation provide that shares of common stock when duly authorized may be issued from time to time for such consideration
as may be fixed by the Board of Directors. Under the laws of the State of New Hampshire and our Articles of Incorporation and <FONT STYLE="white-space:nowrap">By-Laws,</FONT> we can issue additional shares of common stock without further approval of
our shareholders; however, the New York Stock Exchange requires that we obtain shareholder approval for certain issuances of common stock in excess of 20% of the amount outstanding prior to the issuance. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our <FONT STYLE="white-space:nowrap">By-Laws</FONT> require advance notice for annual and special meetings, which notices are always required
to state the purposes for which the meetings are called. Our <FONT STYLE="white-space:nowrap">By-Laws</FONT> also require advance notice of business proposed by shareholders and nominations of directors by shareholders. In addition, our Board of
Directors may make, amend or repeal our <FONT STYLE="white-space:nowrap">By-Laws</FONT> in whole or in part, except with respect to any provision thereof which by statute or by the Articles of Incorporation requires action by our shareholders. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are a public utility holding company under the laws of the State of New Hampshire. Section&nbsp;374:33 of the New Hampshire Revised
Statutes provides that no public utility or public utility holding company may directly or indirectly acquire more than 10&nbsp;percent of the stocks or bonds of another public utility holding company incorporated or doing business in the State of
New Hampshire, without the approval of the Public Utilities Commission of New Hampshire. </P>
