LAKE SUCCESS, N.Y. — DealerTrack Holdings Inc. will appoint Barry Zwarenstein to its board of directors on Nov. 6. Zwarenstein is expected to serve on DealerTrack's Audit Committee.

"We are very pleased to welcome Barry to the DealerTrack board of directors," said Mark O'Neil, DealerTrack's chairman and chief executive officer. "Given the breadth of his experience with other rapidly growing public companies, and his background in M&A and the international arena, we are confident Barry will bring valuable perspective to the board's deliberations."

Zwarenstein joined VeriFone Holdings Inc. in June 2004 as senior vice president and chief financial officer. He was subsequently promoted to executive vice president and chief financial officer. Over the previous eight years, he also served as chief financial officer of Iomega Corporation, Mellanox Technologies Limited, Acuson Corporation and Logitech S.A. Zwarenstein began his career at FMC Corporation, where he held a variety of positions in finance, and at the time of his departure was chief financial officer for FMC Europe.

Zwarenstein received a Bachelor of Commerce degree from the University of Natal, South Africa, and an M.B.A. from the Wharton School of Business at the University of Pennsylvania. He also earned South Africa's Chartered Accountant designation early in his career.

In addition, DealerTrack has announced that Thomas F. Gilman will resign from the board effective on Nov. 5. Gilman's move to an operating role at Cerberus LLC makes it challenging for him to continue to fulfill his responsibilities on the DealerTrack board.

"We would like to thank Tom for his contributions to the growth and development of DealerTrack over the course of this year," said O'Neil.

Gilman said, "I would like to thank everyone at DealerTrack, and especially the members of the Board, for their support and graciousness as I arrived at my decision. I wish you all the best of success in the future."

Due to similar circumstances, it is anticipated that director Thomas R. Gibson, a senior advisor to Cerberus, will resign from the DealerTrack board in the near future. To ensure a smooth transition, Gibson plans to remain a director for DealerTrack until a replacement has been designated.
