                        and Final Quarterly Cash Dividend

KLAMATH FALLS, OR, December 11, 2003 - Klamath First Bancorp, Inc. (Nasdaq KFBI)
today  announced  that its  shareholders  had approved the Agreement and Plan of
Merger  dated July 14,  2003,  which  provides  for the merger of Klamath  First

Under the terms of the merger  agreement,  shareholders of Klamath First Bancorp
will be entitled to receive for each share of Klamath First Bancorp common stock
0.77 shares of Sterling common stock and cash in lieu of any fractional  shares.
The merger has been structured as a tax-free  reorganization  within the meaning

The parties  currently  anticipate that the proposed merger will be completed in
early January 2004, which date will be the last day of trading for Klamath First
Bancorp's stock on the Nasdaq Stock Market.

In  connection  with today's  shareholder  approval,  Klamath First Bancorp also
announced that its Board of Directors  declared a final  quarterly cash dividend
of $0.13 per share of common  stock.  The dividend  will be paid on December 31,
2003 to  shareholders of record on December 19, 2003, just prior to the expected
closing date of the  Klamath/Sterling  merger. This will be the 33rd consecutive
and final cash dividend declared by Klamath First Bancorp.
