Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On April 26, 2016, Pacific Continental Corporation, Eugene, Oregon (“PCBK”) and its subsidiary, Pacific Continental Bank (“PCB”), entered into an Agreement and Plan of Merger (the “Agreement”), with Foundation Bancorp, Inc. (“Foundation”), and its wholly-owned subsidiary, Foundation Bank, a Washington state-chartered bank (“Foundation Bank”), pursuant to which PCBK will acquire Foundation and Foundation Bank.

Subject to the terms and conditions of the Agreement, which has been approved by the board of directors of each party thereto, Foundation will be merged with and into PCBK, with PCBK as the surviving corporation (the “Merger”). Thereafter, pursuant to the terms of the plan of bank merger to be entered into by PCB and Foundation Bank, Foundation Bank will be merged with and into PCB, with PCB surviving.

Subject to the terms and conditions of the Agreement, upon the effectiveness of the Merger, each outstanding share of Foundation common stock will be converted into the right to receive, without interest, either (i) 0.7911 shares of PCBK common stock, or (ii) $12.50 in cash, subject to the payment of cash in lieu of fractional shares and customary adjustment, election and allocation procedures, if necessary to assure that the aggregate cash consideration paid is approximately $19.3 million, subject to potential adjustment. Foundation preferred stock outstanding immediately prior to the effective time of the Merger will be converted into the right to receive the Merger consideration with respect to 1,500,000 shares of Foundation common stock, together with cumulative cash dividends payable to such holders.

The Agreement also provides, among other things, that, effective upon the closing of the Merger, PCBK shall expand the size of its Board of Directors by two seats and designate two Foundation representatives to serve on the Board of Directors of PCBK and PCB.

The boards of directors of each company have unanimously approved this transaction. Completion of the transaction is subject to customary closing conditions, including receipt of bank regulatory approvals and the approval of Foundation’s common and preferred shareholders. The transaction is expected to close by the end of the third quarter of 2016.

The Agreement contains customary representations, warranties and covenants of the parties. The Agreement contains certain termination rights for both PCBK and Foundation, and further provides that, upon termination of the Agreement upon specified circumstances, Foundation may be required to pay PCBK, or PCBK may be required to pay Foundation, a termination fee of $2,000,000.

In connection with the Agreement, PCBK also entered into a Voting and Non-Competition Agreement with each of the directors and certain executive officers of Foundation. Each Voting and Non-Competition Agreement will be effective upon the Closing of the Merger and includes certain non-competition covenants for a period of up to two years following the completion of the Merger. In addition, each signatory of a Voting and Non-Competition Agreement, solely in his or her capacity as a shareholder of Foundation, agreed to vote his or her shares of Foundation common stock in favor of the Merger and against alternative transactions.

Concurrently with entering into the Agreement, PCBK entered into a Voting Agreement with certain executive officers of Foundation, Castle Creek Capital Partners V, L.P. and Thomas Ellison, solely in his, her or its capacity as a shareholder of Foundation, pursuant to which each agreed to vote their shares of Foundation common stock or Foundation preferred stock, as appropriate, in favor of the Merger and against alternative transactions.

The foregoing is not a complete description of the Agreement, the form of Voting and Non-Competition Agreement or the form of Voting Agreement, and is qualified in its entirety by reference to the full text of these agreements, which are filed as Exhibits 2.1, 99.1 and 99.2 hereto and are incorporated herein by reference.

The Agreement and the above description of the Agreement have been included to provide investors and security holders with information regarding the terms of the Agreement and the transactions contemplated thereby. The Agreement and the above description are not intended to provide any other factual information about PCBK, Foundation, or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Agreement were made only for purposes of the Agreement and as of specific dates; were solely for the benefit of the parties to the Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them rather than establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of PCBK, Foundation, or any of their respective subsidiaries, affiliates or businesses. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Agreement, which subsequent information may or may not be fully reflected in public disclosures by PCBK or Foundation. Accordingly, investors should read the representations and warranties in the Agreement not in isolation, but only in conjunction with the other information about PCBK or Foundation and their respective subsidiaries that the respective companies include in reports, statements and other filings they make with the SEC.
