Investor Presentation
Exhibit 99.4


Cautionary Note: Forward-looking Statements
This presentation includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.  All statements
other than statements of historical fact are forward-looking statements.  These forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause Columbia Banking System, Inc.’s (“Columbia”) or Pacific Continental Corporation’s (“PCBK”)
performance or achievements to be materially different from any expected future results, performance, or achievements. 
Forward-looking statements speak only as of the date they are made and neither Columbia nor PCBK assumes any duty to update forward-looking
statements. We caution readers that a number of important factors could cause actual results to differ materially from those expressed in, or
implied or projected by, such forward-looking statements. Such forward-looking statements include, but are not limited to, statements about the
benefits of the business combination transaction involving Columbia and PCBK, including future financial and operating results, the combined
company’s plans, objectives, expectations and intentions and other statements that are not historical facts. The following factors, among others,
could
cause
actual
results
to
differ
from
those
set
forth
in
the
forward-looking
statements:
(i)
the
possibility
that
the
merger
does
not
close
when
expected or at all because required regulatory, shareholder or other approvals and other conditions to closing are not received or satisfied on a
timely basis or at all; (ii) changes in Columbia’s stock price before closing, including as a result of the financial performance of PCBK prior to closing,
or
more
generally
due
to
broader
stock
market
movements,
and
the
performance
of
financial
companies
and
peer
group
companies;
(iii)
the
risk
that the benefits from the transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in
general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree
of competition in the geographic and business areas in which Columbia and PCBK operate; (iv) the ability to promptly and effectively integrate the
businesses of Columbia and PCBK; (v) the reaction to the transaction of the companies’ customers, employees and counterparties; (vi) diversion of
management time on merger-related issues; (vii) lower than expected revenues, credit quality deterioration or a reduction in real estate values or a
reduction in net earnings; and (viii) other risks that are described in Columbia’s and PCBK’s public filings with the Securities and Exchange
Commission (the “SEC”). For more information, see the risk factors described in each of Columbia’s and PCBK’s Annual Reports on Form 10-K,
Quarterly Reports on Form 10-Q and other filings with the SEC.

Accelerates our growth over $10 billion in total assets into mid-2017
COLB started preparing to cross $10 billion in January 2013.  Significant infrastructure
expenses have already been built into our run rate; efforts to date include:
Implemented a robust Compliance Management Program with area compliance experts
embedded within the various functional areas of the bank resulting in an enhanced
compliance-oriented culture
Developed and implemented in 2014 a DFAST compliant stress test model
Expanded the Executive Management team with the addition of the General Counsel function
Various shifts in the senior and middle management organizational structure to more
efficiently manage across a larger asset base
Implemented various Board level corporate governance initiatives, including the addition of
new directors with diversified professional backgrounds and expanded geographic reach, and
improved utilization of board committees
Continue to develop and mature our Enterprise Risk Management program
Subjects COLB to Durbin Amendment in Q3 of 2018 resulting in an annual estimated
loss of pre-tax interchange revenue on a combined proforma basis of approximately
$9.8 million
13
Surpassing the $10 Billion Asset Threshold


Acquisition is in line with COLB’s strategic plan, and meets COLB’s investment
criteria
PCBK provides COLB a solid foothold in the Eugene market with #1 market share
rank and the opportunity to combine some branches in the Seattle and Portland
markets
Culturally compatible banks with similar core deposit bases and commercial
banking orientation
Increased size and scale favorably positions COLB for further growth strategies
Transaction expected to enhance COLB’s long-term shareholder value
