Williams Partners Announces Board of Directors Changes

TULSA, Okla. – Williams Partners L.P. (NYSE: WPZ) today announced changes to its general partner’s board of directors.

Bill Z. Parker resigned his position as an independent director, effective Sept. 7.  Parker, a retired executive vice president of Phillips Petroleum Company, was elected as a member of the board of directors in 2005.  He served on the board’s audit and conflicts committees.

Steve Malcolm, chief executive officer of the general partner of Williams Partners, thanked Parker for his five years of service to the partnership.

“Mr. Parker was the initial independent board member elected upon formation of the partnership in 2005,” Malcolm said.  “His contributions over the years have helped transform Williams Partners into one of the largest diversified energy MLPs in the country.”

H. Brent Austin has been elected to replace Parker, effective Sept. 8.  He will serve on the board’s audit and conflicts committees.

Austin is managing partner and chief investment officer of Alsamora L.P., a Houston-based private limited partnership with real estate and diversified equity investments. Prior to his current position, he was president and chief operating officer of El Paso Corporation, where he managed all non-regulated operations as well as all financial functions.

He was previously a member of the board of directors of Williams Pipeline Partners L.P.’s general partner.  He was elected to that position in 2008.
