Fourth-Quarter Financial Results

Williams Pipeline Partners plans to report its year-end 2009 financial results before the market opens on Thursday, Feb. 18. However, management has cancelled the live webcast and conference call that was previously scheduled for 12 p.m. EST on the same day.

As part of the restructuring, Williams Partners announced it intends to launch an exchange offer for the publicly held units of Williams Pipeline Partners.

Williams Partners will offer a fixed exchange ratio of 0.7584 of its common units for each Williams Pipeline Partners common unit. The ratio is based on Friday, Jan. 15 closing prices on the New York Stock Exchange of $23.35 for Williams Pipeline Partners and $30.79 for Williams Partners.

The exact timing of the launch will be based upon the filing of necessary offering documents with the Securities and Exchange Commission and upon market conditions. The terms of the exchange offer will be fully described in those documents.
