Retirement of Richard G. Reiten from the Northwest Natural Gas Company Board of Directors

As previously reported on March 24, 2008, Richard G. Reiten, Chairman of the Board of Northwest Natural Gas Company (“NW Natural”), notified NW Natural that he intended to retire at the end of his current term, which expired at the end of the 2008 Annual Shareholders Meeting held on May 22, 2008.

The Organization and Executive Compensation Committee has adopted a Board compensation standard practice such that upon the death, total disability or retirement of a director, (i) any unvested shares under the Non-Employee Director Stock Compensation Plan (the “NEDSCP”) will become fully vested (as applicable through the end of 2008), and (ii) such director’s quarterly cash retainer will be paid for the full quarter in which the termination event occurs. In accordance with the standard practice, 379.169 shares of NW Natural Common Stock awarded to Mr. Reiten under the NEDSCP which otherwise would remain unvested as of May 22, 2008, were vested by the Board, and all cash retainers payable to Mr. Reiten for his service as a director and Chairman of the Board were paid in full through June 30, 2008.
