IMPORTANT NOTICE

January 3, 2011

Dear fellow Northeast Utilities shareholder:

On October 18, 2010, Northeast Utilities (NU) and NSTAR announced a merger of equals that will create the largest utility company in New England. I firmly believe the merger will provide significant benefits to our shareholders and customers and to the region as a whole. NSTAR serves 1.1 million electric and 300,000 natural gas distribution customers in eastern Massachusetts, so its service territory complements our Connecticut, New Hampshire and western Massachusetts service territories very well. Like NU, NSTAR focuses primarily on electric transmission and distribution and natural gas distribution. Together, we will serve 3 million electric and 500,000 natural gas distribution customers.

PROXY MATERIAL WILL BE SENT TO YOU SHORTLY

Later this month, you will receive a joint proxy statement/prospectus concerning a Special Meeting of NU shareholders that is scheduled for March 4, 2011. I urge you to read this document when you receive it. You will be asked to consider four proposals concerning the merger. Your Board of Trustees has unanimously approved the merger agreement and urges you to vote “FOR” each of the proposals promptly after reviewing the joint proxy statement/prospectus, whether or not you plan to attend the Special Meeting. We expect the merger to be accretive to earnings the first year after it closes and we believe the merger will enhance the value of your NU shares. Additionally, subject to the conditions of the merger agreement, NU’s first quarterly dividend declared after the merger is completed will be increased to achieve parity with NSTAR’s then current dividend. Based on NSTAR’s current annualized dividend rate, that would result in an annualized NU dividend of approximately $1.30 per common share. In 2010, NU’s annualized dividend was $1.025 per common share. Of course, the payment of dividends by NU remains subject to applicable law and the discretion of the Board of Trustees.

The four proposals you will be asked to consider are:

 

  1. To approve the merger, including the issuance of NU common shares to NSTAR shareholders. The number of NU common shares you own will not change as a result of the merger and there will be no need for you to exchange your current NU common shares.

 

  2. To increase the number of authorized Northeast Utilities common shares.

 

  3. To fix the number of NU trustees at 14.

 

  4. To adjourn the Special Meeting, if necessary, to solicit additional proxies.

YOUR VOTE IS VERY IMPORTANT

Completion of the merger is subject to several conditions, including the approval of each company’s shareholders, as well as from certain state and federal regulators. Please note that the merger proposal requires the affirmative vote of the holders of at least two-thirds of outstanding Northeast Utilities common shares, so every shareholder’s vote is very important.

If you have questions concerning this merger, please contact our Investor Relations group at (860) 728-4652 or (860) 728-4650. Thank you in advance for your support and for your investment in our company.

 

Sincerely,
