PART III

Item 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT

Directors of the Corporation

The Corporation has a classified Board of Directors (the "Board") consisting of three Class I directors, two Class II directors and two Class III directors. Thomas A. Hurkmans served as a Class III director from his election to the Board on March 15, 2000 until his resignation from the Board on December 31, 2001. On January 25, 2002, Anthony J. Villiotti was appointed to the Board to fill the vacancy resulting from the resignation of Mr. Hurkmans. At each Annual Meeting of Stockholders, directors are elected for a full term of three years to succeed those whose terms are expiring.

For each member of the Board there follows information given by each concerning his principal occupation and business experience for the past five years, the name of other publicly held companies on which he serves as a director and his age and length of service as a director of the Corporation.

No director or executive officer is related by blood, marriage or adoption to any other director or executive officer.

Pursuant to the Securities Purchase Agreement (the "1997 Securities Purchase Agreement"), dated as of May 28, 1997, by and among the Corporation, Beacon Power Corporation ("Beacon Power"), an affiliate of the Corporation, and DQE Enterprises, Inc. ("DQE Enterprises"), Mr. Villiotti was first elected to the Board on June 30, 1997. On January 13, 2000, Mr. Villiotti resigned from his position as a director of the Corporation, and the Board appointed Mr. Hurkmans, as the representative of DQE Enterprises, to fill the vacancy resulting from the resignation of Mr. Villiotti. Mr. Hurkmans was elected to the Board by the stockholders on March 15, 2000 and served as a director of the Corporation until his resignation on December 31, 2001. Pursuant to the terms of the 1997 Securities Purchase Agreement, as long as DQE Enterprises owned five percent (5%) of the Corporation's Common Stock (the "Common Stock"), the Corporation was required to recommend that the Corporation's stockholders vote for DQE Enterprises' representative and cause to be voted for such representative the shares of Common Stock for which the Corporation's management or Board holds proxies or are otherwise entitled to vote. DQE Enterprises no longer owns 5% of the Common Stock and, since the resignation of Mr. Hurkmans in December 2001, has no representative on the Board. Mr. Villiotti's appointment to the Board on January 25, 2002 to fill the vacancy resulting from the resignation of Mr. Hurkmans was not pursuant to, or in connection with, the 1997 Securities Purchase Agreement or any other arrangement between the Corporation and DQE Enterprises.

Pursuant to the Securities Purchase Agreement (the "1999 Securities Purchase Agreement"), dated as of October 21, 1999, between the Corporation and Mechanical Technology Incorporated, Mr. Goldberg was elected to the Board as of November 15, 1999. Pursuant to the terms of the 1999 Securities Purchase Agreement, as long as Mechanical Technology Incorporated owns five percent (5%) of the Common Stock, the Corporation must recommend that the Corporation's stockholders vote for Mechanical Technology Incorporated's representative. The Corporation has also agreed to appoint an additional member to the Board based on recommendations by Mechanical Technology Incorporated.

In consideration for the acquisition of Ling Electronics and an investment by Mechanical Technology Incorporated in the Corporation, Mechanical Technology Incorporated received a total of 1,800,000 shares of the Common Stock and warrants to purchase an additional 100,000 shares of the Common Stock at an exercise price of $8.80 per share. On October 21, 1999, Mechanical Technology Incorporated funded $2,570,000 of its investment in the Corporation and received 370,800 shares of Common Stock and issued a warrant to the Corporation to purchase 108,000 shares of Mechanical Technology Incorporated's common stock at an exercise price of $12.56 per share. At a second closing of Mechanical Technology Incorporated's investment, on January 31, 2000, the Corporation issued to Mechanical Technology Incorporated 659,200 shares of the Common Stock and a warrant to purchase an additional 64,000 shares of the Common Stock at an exercise price of $8.80 per share in exchange for $4,500,000 in cash and a warrant to purchase 192,000 shares of Mechanical Technology Incorporated's common stock at an exercise price of $12.56 per share. In connection with these transactions, Alan P. Goldberg, then a director of Mechanical Technology Incorporated and President of First Albany Companies Inc., was elected a member of the Board on November 15, 1999. Mr. Goldberg resigned from the board of directors of Mechanical Technology Incorporated in December 2002. The Corporation has also agreed to appoint an additional member to the Board based on recommendations by Mechanical Technology Incorporated, and Mechanical Technology Incorporated agreed to appoint Mr. Eisenhaure to its board of directors. Mr. Eisenhaure currently serves on the board of directors of Mechanical Technology Incorporated.

Consulting Agreement with Marshall J. Armstrong

On July 19, 2000, the Corporation entered into a consulting agreement with Marshall J. Armstrong, one of its directors. In consideration for Mr. Armstrong providing consulting, advisory and related services under the consulting agreement, the Corporation has agreed to pay Mr. Armstrong $2,000 per day (which amount will be proportionately less for partial days) for services performed as well as reimbursement of reasonable and necessary expenses incurred by Mr. Armstrong in connection with the consulting agreement. To date, the Corporation has paid Mr. Armstrong $3,000 under the terms of the consulting agreement since entering into the consulting agreement in July 2000.

The Corporation believes that each of the transactions described above was carried out on terms that were no less favorable to the Corporation than those that would have been obtained from unaffiliated third parties.
