On October 22, 2013, on the recommendation of the Chairman of the Board of American DG Energy Inc., or the Registrant, the Board of Directors appointed Mr. John Rowe as a member of Registrant’s Board of Directors. Mr. Rowe shall hold such position until the next annual meeting of the stockholders of the Registrant or until his successor shall have been duly elected and qualified.

Mr. Rowe is Chairman Emeritus of Exelon Corporation, a utility holding company which he has led since its formation in 2000.  Mr. Rowe retired as Chief Executive Officer of Exelon in March 2012.  Exelon Corporation is the nation's leading competitive energy provider, with approximately $23.5 billion in annual revenues.  Previous roles include chief executive officer positions at New England Electric Systems and Central Maine Power Company.  Mr. Rowe served as general counsel of Consolidated Railroad and was a partner in the law firm of Isham, Lincoln and Beale.

The Registrant’s Board of Directors has determined that Mr. Rowe’s prior experience in senior operating positions at various companies, where he demonstrated leadership capability and garnered extensive operating expertise qualify him to be a member of the Board of Directors in light of Registrant’s business and structure.

Mr. Rowe has no family relationships with any directors or executive officers of the Registrant. He will receive a fee of $500 per day for his service as a member of the Board of Directors of the Registrant and has been granted a nonqualified option award to purchase 80,000 shares of the Registrant’s common stock with an exercise price equal to the fair market value of Registrant’s common stock on the date of the grant. Those options will vest in 4 equal annual installments and will expire on the tenth anniversary of the date of the grant.
