KLAMATH FIRST TO SELL SEVEN BRANCHES

TO THE BANK OF EASTERN OREGON

KLAMATH  FALLS,  OREGON -  September  10,  2003 - Klamath  First  Bancorp,  Inc.
(Nasdaq:  KFBI)  announced  today that Klamath  First Federal had agreed to sell
seven branches located in northeastern Oregon to the Bank of Eastern Oregon. The
branches  that will be sold are located in the towns of Burns,  Condon,  Fossil,
Heppner,  John Day, Prairie City and Moro. The sale includes deposit accounts of
approximately  $66  million,  which will  double the size of the Bank of Eastern
Oregon's six branches, and its $78 million in total assets. The fixed assets and
branch locations will also be included in the sale;  however,  loans will not be
included.  It is  anticipated  that  the  Bank  of  Eastern  Oregon  will  offer
employment to all current branch employees.

Kermit K. Houser,  President and Chief Executive Officer commented,  "As part of
our  strategic  plan  management  and the Board of Directors  have looked at the
possibility of branch sales, closures and consolidations in an effort to improve
Klamath  First's  operating  efficiency  over the past year but did not have any
specific  areas or  branches  targeted.  With  the  recent  announcement  of our
proposed merger with Sterling  Financial  Corporation  (Nasdaq:  STSA),  several
community  banks  indicated an interest in many of our rural  branch  locations.
Klamath First  determined  that Bank of Eastern Oregon was the best candidate to
acquire its branches since Bank of Eastern Oregon shared Klamath First Federal's
commitment to customers and  employees.  In addition,  a sale at this time would
ensure  that the  Klamath  First  customers  and  employees  at  these  branches
experience only one organizational change rather than two.

We do not  anticipate  any further  sales or  closures of branches  prior to the
Sterling merger," added Mr. Houser.

"The Bank of Eastern Oregon is pleased to offer customers and employees of these
branches the opportunity to join our great team. We were  established in 1945 to
meet the  financial  needs of rural  communities  in eastern  Oregon,  and these
branch  purchases  will allow us to continue that  tradition in markets and with
customers we are very familiar with," stated George Koffler, President and Chief
Executive  Officer  of the  Bank  of  Eastern  Oregon.  Bank of  Eastern  Oregon
currently intends to partially finance the proposed branch  acquisition  through
the issuance of $2 million of Trust Preferred Securities.

As  previously  announced,  Klamath is party to a merger  agreement  pursuant to
which  Klamath  will merge into  Sterling  Financial  Corporation.  Sterling was
apprised of and concurred in the sale of these seven  branches.  The branch sale
is expected to close in December subject to regulatory approval.
