Upon completion of the Merger, each share of Intermountain common stock will be converted into the right to receive consideration consisting of shares of Columbia common stock or cash, or a unit consisting of a mix of Columbia common stock and cash, pursuant to the terms of the Agreement and Plan of Merger, a copy of which is attached as Appendix A to the Proxy Statement/Prospectus dated September 23, 2014.

If an Intermountain shareholder fails to submit an Election Statement to the Exchange Agent prior to the Election Deadline, or if an Election Statement is improperly completed and/or is not signed, such shareholder will be deemed to have made no election and will be issued in respect of each share of Intermountain common stock held by such shareholder a unit consisting of Columbia common stock and cash.

The transaction has received the requisite approvals from the Federal Deposit Insurance Company, the Washington Department of Financial Institutions and the Idaho Department of Finance.
