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

On September 19, 2011, two investors separately notified Intermountain Community Bancorp (the “Company”) that each was terminating, effective immediately, its respective Securities Purchase Agreement (as defined below). As disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 7, 2011, on April 6, 2011 the Company entered into securities purchase agreements (each, a “Securities Purchase Agreement” and collectively, the “Securities Purchase Agreements”) with Castle Creek Capital Fund IV (“Castle Creek”), affiliates of Stadium Capital Management, LLC, and 14 other investors (each an “Investor,” and collectively, the “Investors”), pursuant to which the Investors agreed to invest in private placements an aggregate of $70 million in the Company for 70 million newly issued shares of the Company’s common stock (the “Common Stock”) at a purchase price of $1.00 per share and, with respect to Castle Creek, a three-year warrant to purchase an additional 1,000,000 shares of Common Stock at $1.25 per share. Under the Securities Purchase Agreements, each terminating Investor had agreed to purchase shares of Common Stock that would have represented approximately nine percent of the outstanding shares of Common Stock after giving effect to the private placements. However, the two nine-percent Investors elected to terminate their respective Securities Purchase Agreements pursuant to the provision allowing such termination if the transactions were not complete on or prior to August 31, 2011.

As reported in the Company’s Form 8-K filed April 7, 2011, the closing of the transactions was subject to certain customary conditions including required bank regulatory approvals and confirmations for the transactions. The Company and each appropriate Investor filed all necessary notices and filings with applicable bank regulators; however, all required approvals were not obtained by August 31, 2011. It is a condition to each remaining Investor’s obligation to close the transactions that the full $70 million in capital be raised. As a result, the transactions must be re-structured in order for this closing condition to be satisfied with respect to the other Investors.

The Company is working with its placement agent, Sandler O’Neill + Partners, L.P., and its other advisors to complete the transactions as quickly as possible.

The matters reported under Item 1.02 above are incorporated herein by reference.
