VOTING AND NON-SOLICITATION AGREEMENT

Exhibit 99.4

EXECUTION VERSION

VOTING AND NON-SOLICITATION AGREEMENT

This Voting and Non-Solicitation Agreement (“Agreement”), dated as of July 23, 2014, is entered into by and among Columbia Banking System, Inc., a Washington corporation (“Parent”), Intermountain Community Bancorp, an Idaho corporation (the “Company”), and each person executing this Agreement or a counterpart to this Agreement, each of whom is a member of the Board of Directors of the Company (each, a “Director”).

RECITALS

A. Pursuant to the terms of the Agreement and Plan of Merger (as the same may be amended or supplemented, the “Merger Agreement”), dated as of the date hereof, between Parent and the Company, the Company will be merged with and into Parent (the “Merger”) and Panhandle State Bank, an Idaho state-chartered bank and wholly-owned subsidiary of the Company (“Panhandle State Bank”), will be merged with and into Columbia State Bank, a Washington state-chartered bank and wholly-owned subsidiary of Parent.

B. The parties to this Agreement believe that the future success and profitability of Parent and its subsidiaries following the Merger (the “Combined Company”), requires that the Directors be subject to the restrictions set forth herein with respect to solicitation activities following the closing of the Merger as set forth herein.

C. As an inducement and a condition to Parent entering into the Merger Agreement, Parent has required that each Director, in his capacity as a shareholder of the Company, enter into this Agreement to make more likely the approval of the Merger by the requisite vote of the Company’s shareholders, to minimize the risk that Parent will lose the benefit of the goodwill and other assets being acquired by it, and to protect the trade secrets and other confidential and proprietary information of the Company known to each Director and being acquired by Parent.

AGREEMENT

In consideration of Parent’s and the Company’s performance under the Merger Agreement, each Director agrees as follows:

1. Definitions. Capitalized terms not defined in this Agreement have the meaning assigned to those terms in the Merger Agreement. The following definitions also apply to this Agreement:

(a) Competing Business. “Competing Business” means any depository, wealth management or trust business company or holding company thereof (including without limitation, any start-up bank or bank in formation) operating anywhere within the Covered Area.

(b) Covered Area. “Covered Area” means the State of Idaho and the counties listed in Annex 1 located in the State of Washington.

(c) Term. “Term” means the period of time beginning on the Effective Time and ending two (2) years after the Effective Time.

2. Effectiveness. If the Merger Agreement is terminated for any reason in accordance with its terms, this Agreement (other than Sections 4 and 5 and Sections 12 through 20) shall automatically terminate and be null and void and of no effect.

3. No Solicitation. During the Term, the Director will not, directly or indirectly, either for himself or any other Person, (a) solicit or induce, or attempt to solicit or induce (i) any employees or independent contractors (or any former employees or independent contractors within the six months preceding such solicitation) of the Combined Company to participate, as an employee or otherwise, in any manner in a Competing Business, (ii) any customers, business partners or joint venturers of the Combined Company to transfer their business to a Competing Business or to reduce their business or cease conducting business with the Combined Company, or (iii) the termination of an employment or contractual relationship between the Combined Company and any employee, independent contractor, customer, business partner or joint venturer, (b) hire any Person then employed by the Combined Company, or who was employed by the Company or its subsidiaries or the Combined Company at any time during the two-year period prior to the Effective Time; provided, however, the Director shall not be prohibited from, directly or indirectly, hiring for himself or a Competing Business, former employees of the Combined Company if such employees were terminated by Parent and a period of not less than ninety (90) days from the date of such former employee’s termination has passed, or (c) in any other way interfere with or disrupt the Combined Company’s relationship with any of its employees, independent contractors, customers, business partners or joint venturers. Solicitation prohibited under this Section 4 includes solicitation by any means, including, without limitation, meetings, letters or other mailings, electronic communications of any kind, and internet communications.

4. Confidential Information. From and after the date of this Agreement, the Director shall not at any time, directly or indirectly, divulge, reveal or communicate any confidential information of Parent, the Company or their respective Subsidiaries obtained by such Person while serving as a director of the Company or Panhandle State Bank to any Person, or use any confidential information for his own benefit or for the benefit of any other Person except in accordance with a judicial or other governmental order in compliance with Section 5. For purposes of this Agreement, “confidential information” shall include (a) all secrets and other confidential information, ideas, knowledge, knowhow, techniques, secret processes, improvements, discoveries, methods, inventions, sales, financial information, customers, lists of customers and prospective customers, broker lists, potential brokers, rate sheets, plans, concepts, strategies or products, as well as all documents, reports, drawings, designs, plans, and proposals otherwise pertaining to same, with respect to Parent, the Company, the Combined Company or their respective Subsidiaries, plus any non-public personal information on any present or past customer or client of the Company, Panhandle State Bank or the Combined Company. For purposes of this Agreement “confidential information” does not include (a) information that is or becomes generally available to the public other than as a result of an unauthorized disclosure by such Director; (b) information that was in the Director’s possession prior to serving as a director or information received by the Director from another Person without any limitations on disclosure, but only if the Director had no reason to believe that the other Person was prohibited from using or disclosing the information by a contractual or fiduciary obligation; or (c) was independently developed by the Director without using any confidential information of Parent, the Company, the Combined Company or their respective Subsidiaries.

5. Legally Required Disclosure. If the Director is requested or required by any tribunal or government agency (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process), to disclose any confidential information that would violate the other provisions of this Agreement, the Director shall provide Parent with prompt notice of any such request or requirement and shall provide, at Parent’s expense, such reasonable cooperation as Parent may request so that Parent may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement as it would apply to such requested or required disclosure. If, in the absence of a protective order or other remedy or the receipt of a written waiver from Parent, the Director is nonetheless legally compelled to disclose confidential information to any tribunal or government agency, the Director may, without liability hereunder, disclose to such tribunal or government agency only that portion of confidential information which is legally required to be disclosed; provided that the Director exercises his reasonable efforts to preserve the confidentiality of such confidential information, including, without limitation, by reasonably cooperating with Parent, at its expense, to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded to such confidential information by such tribunal or government agency.

6. Voting Agreement. From the date hereof until the earlier of (i) the Effective Time and (ii) the termination of the Merger Agreement in accordance with its terms (the “Support Period”), the Director agrees that at any shareholder meeting of the Company to approve the Merger or any related transaction, or any adjournment or postponement thereof, the Director shall be present (in person or by proxy) and shall vote (or cause to be voted) all of his voting shares of capital stock of the Company entitled to vote at such meeting (together, “Owned Shares”): (a) in favor of approval of (1) the Merger Agreement and the transactions contemplated thereby, (2) any other matter that is required to facilitate the transactions contemplated by the Merger Agreement and (3) any proposal to adjourn or postpone such meeting to a later date if there are not sufficient votes to approve the Merger Agreement; and (b) against any action or agreement submitted for approval to the shareholders of the Company that would (1) result in breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement, (2) result in any of the conditions to the consummation of the Merger under the Merger Agreement not being fulfilled, or (3) impair the ability of Parent to complete the Merger, the ability of the Company to complete the Merger, or that would otherwise be inconsistent with, prevent, impede or delay the consummation of the transactions contemplated by the Merger Agreement; provided, that the foregoing applies solely to the Director in his capacity as a shareholder and nothing in this Agreement shall prevent the Director from discharging his fiduciary duties with respect to his role on the Board of Directors of the Company. The Director covenants and agrees that, except for this Agreement, he (a) has not entered into, and shall not enter during the Support Period any voting agreement or voting trust with respect to the Owned Shares, (b) has not granted, and shall not grant during the Support Period a proxy, consent or power of attorney with respect to the Owned Shares except any proxy to carry out the intent of this Agreement, and (c) has not taken and shall not take any action that would have the effect of preventing or disabling the Director from performing any of its obligations under this Agreement.

8. Resignation from the Company Board. The Director hereby tenders his resignation from the Board of Directors of the Company and of Panhandle State Bank subject to and effective upon the Effective Time.

9. Expenses.

The Director further agrees that neither Parent nor any other Person or entity shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this paragraph, and the Director irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

13. Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Washington applicable to contracts made and performed entirely within such state, without giving effect to its principles of conflicts of laws.

Whenever possible, each provision or portion of any provision of this Agreement, including Section 3, will be interpreted in such manner as to be effective and valid under applicable law but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision or portion of any provision had never been contained herein.

17. Individual Obligations. The obligations of each of the Directors under this Agreement are several and not joint. This Agreement is binding on each Director that executes this Agreement regardless of whether any other Director(s) also executed this Agreement.

No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.
