EXPLANATORY STATEMENT

This post-effective amendment to the registration statement on Form S-8 (Registration No. 333-109501) (the “Registration Statement”) is being filed by Pacific Continental Corporation (the “Registrant” or “Pacific”) to deregister 720,812 shares of its common stock (as adjusted for subsequent stock splits and stock dividends) previously registered under the Registration Statement with respect to shares reserved for issuance under the Registrant’s 1999 Employee Stock Option Plan and 1999 Director Stock Option Plan (collectively the “1999 Plans”). Under the Registration Statement and Registration Statement No. 333-86632, an aggregate of 2,100,000 shares (as adjusted for subsequent stock splits and stock dividends) were registered for issuance under the 1999 Plans. As of this date, 812,025 shares remain subject to granted but unexercised options under the 1999 Plans.

At the 2006 Annual Shareholder Meeting, shareholders approved the 2006 Stock Option and Equity Compensation Plan (the “2006 Plan”). The 2006 Plan supersedes the 1999 Plans and as a result, Registrant has terminated all further offerings of its common stock under the 1999 Plans and pursuant to the Registration Statement. On June 2, 2006, the Registrant filed a registration statement on Form S-8 (Registration No. 333-134702) to register 500,000 shares of its common stock for issuance under the 2006 Plan.

In accordance with an undertaking made by Pacific in the Registration Statement to remove from registration, by means of a post-effective amendment, any shares of the Registrant’s common stock which remain unsold at the termination of the offering, the Registrant removes from registration all shares of Pacific common stock registered under the Registration Statement which are not subject to granted but unexercised stock options as of the Effective Time.
