Attention: Ward Graffam

Dear Mr. Graffam:

The purpose of this letter is to advise you that Maine & Maritimes Corporation (the “Company”) is negotiating a merger of the Company with a subsidiary of BHE Holdings, Inc. (the “Transaction”). The signing of a merger agreement would constitute an event of default under the following agreements between the Company’s wholly-owned subsidiaries and Bank of America:

We hereby request Bank of America’s consent to the signing of the merger agreement, including an acknowledgement that Bank of America does not consider the signing of the merger agreement to be an event of default, with the understanding that we will need one or more additional consents in order to consummate the Transaction if Bank of America will continue to be a lender to the Company or any of its affiliates after the closing. We understand that this consent does not apply to any matters other than our entering into the merger agreement and that we are still obligated to comply with the terms of the applicable loan and security documents. We also agree to keep you informed about the progress of the Transaction. We would appreciate it if you would indicate your consent by signing on the following page. Please fax or mail the signed consent to the attention of Patrick C. Cannon, General Counsel for the Company, 209 State Street, Presque Isle, Maine 04769, facsimile (207) 760-2423, telephone (207) 760-2422.
