WEST COAST BANCORP TO CONSOLIDATE AFFILIATE BANKS, NORTHWEST HOLDING COMPANY
CONTINUES EMPHASIS ON COMMUNITY FOCUS

LAKE OSWEGO, Ore. - Sept. 15, 1998 -West Coast Bancorp (Nasdaq:WCBO), the
Northwest-based community bank holding company, announced today that it plans to
combine its four separate banking affiliates into a single community-focused
bank.

The name West Coast Bank is being reserved for the consolidated company. The
combination is designed to continue West Coast Bancorp's longstanding commitment
to community banking while increasing its effectiveness in serving customers by
strengthening the company's marketing and brand identity and improving
efficiency.

The board of directors of the new West Coast Bank will consist of the same
members as West Coast Bancorp, assuring continued representation from each of
the markets served by the bank. The consolidation will result in certain
one-time costs when fully implemented and is expected to result in annual
savings in excess of the one-time expenses.

The consolidated bank will be wholly owned by West Coast Bancorp and will be
headquartered in Lake Oswego, Oregon. It will have $1.2 billion in assets and 41
offices in western Oregon and Washington. The consolidation is expected to be
completed in the fourth quarter of 1998, following regulatory approvals. It is
expected that the bank's new name will be in place at its locations around
year-end 1998.

"Our core values remain the same after this consolidation," said Victor L.
Bartruff, president and chief executive officer of West Coast Bancorp. "They
are: a commitment to the communities we serve; relationship-based customer
service; and an open, trusting, integrity-based environment. At the same time,
we expect to speed our decision-making processes, increase efficiency, and put
more emphasis on customer service and less on internal structure. In today's
mobile society, we believe customers will welcome this combination of our family
of community banks under a common name, and the fact that we can deliver
improved service at a lower cost under the new structure. We have strengthened
and realigned our corporate management to prepare for this change, including the
addition of Ron DeLude as chief operating officer, and we are enthusiastic about
the positive results we expect from the changes announced today." DeLude has
been president of Bank of Vancouver, Vancouver, Washington, an affiliate of West
Coast Bancorp.

As a result of the consolidation, West Coast Bancorp expects to reduce
employment by approximately 100 positions or 13% of its total work force. The
affected positions are primarily held by administrative and back office
personnel whose functions can be more effectively handled centrally. West Coast
Bancorp will attempt to find positions within the company for the individuals
whose jobs are affected by the changes, and will offer a severance package to
individuals who are not able to find another position in the new bank.

The company anticipates one-time costs of approximately $5 million to cover
costs of the consolidation, including the severance program, signage, data
conversions and other marketing/branching, regulatory and administrative costs.
Of the one-time expenses, approximately $2 million is expected to be charged
against third-quarter 1998 results, with the remaining costs to be expensed as
incurred in the following several quarters.

The company expects that the consolidation will save approximately $6 million
annually or 12% of its current ongoing overhead expenses. The cost savings will
come from the reductions in staff and related overhead, a simplified corporate
structure, a reduced regulatory burden and synergies created by unified
marketing efforts and name branding. The plan calls for two-thirds of the cost
savings to be substantially achieved by third-quarter 1999, with the remaining
savings to be achieved early in the year 2000.
