AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of August 7, 2014 (this “Agreement”), by and between Banner Corporation, a Washington corporation (“Banner”), and Siuslaw Financial Group, Inc., an Oregon Corporation (“Siuslaw”, and together with Banner, the “Parties”).

RECITALS

A. The Boards of Directors of the Parties have determined that it is advisable and in the best interests of their respective companies and their shareholders to consummate the business combination transaction provided for in this Agreement in which Siuslaw will, on the terms and subject to the conditions set forth in this Agreement, merge with and into Banner (the “Merger”), with Banner as the surviving corporation in the Merger (sometimes referred to in such capacity as the “Surviving Company”).

B. As a condition to the willingness of Banner to enter into this Agreement, all of the directors and executive officers of Siuslaw have entered into voting agreements (each a “Voting Agreement”), substantially in the form attached hereto as Exhibit A, dated as of the date hereof, with Banner.

C. As a condition to the willingness of Banner to enter into this Agreement, all of the directors and executive officers of Siuslaw have entered into resignation (in the case of directors only), non-solicitation and confidentiality agreements (each a “Non-Solicitation Agreement”), substantially in the form attached hereto as Exhibit B, dated as of the date hereof but effective upon consummation of the Merger, with Banner.

D. The Parties intend the Merger to be treated as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and intend for this Agreement to constitute a “plan of reorganization” within the meaning of United States Department of Treasury (“Treasury”) Regulations section 1.368-2(g).

E. The Parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this Agreement, the Parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger.

(a) Subject to the terms and conditions of this Agreement, in accordance with the Washington Business Corporation Act (“WBCA”) and the Oregon Business Corporation Act (“OBCA”), at the Effective Time (as defined in Section 1.2), Siuslaw shall merge with and into Banner. Banner shall be the Surviving Company in the Merger and shall continue its existence as a corporation under the laws of the State of Washington. As of the Effective Time, the separate corporate existence of Siuslaw shall cease.

(b) Subject to the consent of Siuslaw, which shall not be unreasonably withheld or delayed, Banner may at any time change the method of effecting the combination (including by providing for the merger of a wholly owned subsidiary of Banner with Siuslaw) if and to the extent requested by Banner; provided, however, that no such change or amendment shall (i) alter or change the amount or kind of the Merger Consideration (as defined in Section 1.4(b)) to be received by the shareholders of Siuslaw, (ii) adversely affect the tax consequences of the Merger to the shareholders of Siuslaw or the tax treatment of either party pursuant to this Agreement or (iii) impede or materially delay consummation of the transactions contemplated by this Agreement.

1.2 Effective Time. Subject to the terms and conditions of this Agreement, simultaneously with the Closing (as defined in Section 9.1), the Parties shall execute, and Banner shall cause to be filed with the Secretary of State of the State of Washington (the “Washington Secretary”) and the Secretary of State of the State of Oregon (the “Oregon Secretary”) articles of merger as provided in the WBCA and OBCA (collectively the “Articles of Merger”) and a short form plan of merger, if applicable. The Merger shall become effective at such time as designated in the Articles of Merger or if no time is designated at the time of filing with the Washington Secretary (the “Effective Time”).

1.3 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the WBCA and the OBCA.

1.4 Conversion of Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Siuslaw, Banner or the holders of any of the following securities:

(a) Each share of common stock, $0.01 value, of Banner (“Banner Common Stock”) issued and outstanding immediately prior to the Effective Time shall continue to be one validly issued, fully paid and nonassessable share of common stock, $0.01 par value, of the Surviving Company.

(b) Subject to Sections 1.4(c), 1.4(d) and 1.4(e), each share of common stock, $1.00 par value, of Siuslaw (“Siuslaw Common Stock”) issued and outstanding immediately prior to the Effective Time (which shall consist of the 3,992,937 shares of Siuslaw Common Stock outstanding on the date hereof and 102,484 shares of Siuslaw Preferred Stock (as defined in Section 3.2(a)) outstanding on the date hereof that are automatically converted to 102,484 shares of Siuslaw Common Stock prior to the Effective Time)), including Trust Account Common Shares and DPC Common Shares (as such terms are defined in Section 1.4(c)), but excluding any Cancelled Shares (as defined Section 1.4(c) and Dissenting Shares (as defined in Section 1.4(e)), shall be converted, in

accordance with the procedures set forth in Article II, into the right to receive $1.41622 in cash without interest plus 0.32231 (the “Exchange Ratio”) of a share of Banner Common Stock (collectively the “Merger Consideration”). All of the shares of Siuslaw Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of Siuslaw Common Stock (each, a “Certificate”), (it being understood that any reference to “Certificate” shall be deemed, as appropriate, to include reference to book-entry account statements relating to the ownership of Siuslaw Common Stock, and it being further understood that provisions herein relating to Certificates shall be interpreted in a manner that appropriately accounts for book-entry shares, including that, in lieu of delivery of a Certificate and a letter of transmittal as specified herein, shares held in book-entry form may be transferred by means of an “agent’s message” to the Exchange Agent (as defined in Section 2.1) or such other similar evidence of transfer as the Exchange Agent may reasonably request), shall thereafter represent only the right to receive the Merger Consideration and/or any cash in lieu of a fractional share interest into which the shares of Siuslaw Common Stock represented by such Certificate have been converted pursuant to this Section 1.4 and Section 2.3(f), as well as any dividends as provided in Section 2.3(c).

(c) All shares of Siuslaw Common Stock that are owned immediately prior to the Effective Time by Siuslaw or Banner (other than shares of Siuslaw Common Stock held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties (any such shares, “Trust Account Common Shares”) and other than shares of Siuslaw Common Stock held, directly or indirectly, by Siuslaw or Banner in respect of a debt previously contracted (any such shares, “DPC Common Shares”)) shall be cancelled and shall cease to exist and no stock of Banner or other consideration shall be delivered in exchange therefor (any such shares, the “Cancelled Shares”).

(d) Notwithstanding anything in this Agreement to the contrary, all shares of Siuslaw Common Stock (inclusive of those shares automatically converted from Siuslaw Preferred Stock to Siuslaw Common Stock) that are issued and outstanding immediately prior to the Effective Time and which are held by a shareholder who does not vote in favor of the Merger (or consent thereto in writing) and who exercises dissenters rights when and in the manner required under Sections 60.561 to 60.594 of the Oregon Revised Statutes (the “ORS”) shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead such holder shall be entitled to only such rights as are granted with respect to the payment of the fair value of such shares under the applicable provisions of Sections 60.561 through 60.594 of the ORS (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the foregoing provisions of the ORS and this Section 1.4(d)), unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost rights to demand or receive the fair value of such shares of Siuslaw Common Stock under the ORS. If any shareholder dissenting pursuant to the ORS and this Section 1.4(d) shall have failed to perfect or shall have effectively withdrawn or lost such right, such holder’s shares of Siuslaw Common Stock shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration for each such share of Siuslaw Common Stock in accordance with Section 1.4(b), without any interest thereon. Siuslaw shall give Banner (i) prompt notice of any written notices of intent to demand payment under Section 60.564 of the ORS or other written notices relating to the exercise of dissenters’ rights in respect of any shares of Siuslaw Common Stock, attempted withdrawals of such notices and any

other instruments served pursuant to the Sections 60.561 through 60.594 of the ORS and received by Siuslaw relating to shareholders’ dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the ORS. Siuslaw shall not, except with the prior written consent of Banner, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Article II to pay for shares of Siuslaw Common Stock for which dissenters’ rights have been perfected shall be returned to Banner upon demand.

(e) If, between the date of this Agreement and the Effective Time, the outstanding shares of Banner Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, and such change would have an economic effect on the value of the stock portion of the Merger Consideration, then an appropriate and proportionate adjustment shall be made to the Exchange Ratio to provide the holders of Siuslaw Common Stock converted into Merger Consideration the same economic effect as contemplated by this Agreement with respect to the stock portion of the Merger Consideration prior to such event.

1.5 Incorporation Documents and By-Laws of the Surviving Company. At the Effective Time, the articles of incorporation of Banner in effect immediately prior to the Effective Time, shall be the articles of incorporation of the Surviving Company until thereafter amended in accordance with applicable law. The by-laws of Banner, as in effect immediately prior to the Effective Time, shall be the by-laws of the Surviving Company until thereafter amended in accordance with applicable law and the terms of such by-laws.

1.6 Directors and Officers. The directors and officers of Banner immediately prior to the Effective Time shall be the directors and officers of the Surviving Company and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

1.7 The Bank Merger. Immediately after the Effective Time, Banner intends to merge Siuslaw Bank, an Oregon chartered commercial bank and wholly owned subsidiary of Siuslaw, with and into Banner Bank, a Washington chartered commercial bank and wholly owned subsidiary of Banner (the “Bank Merger”) in accordance with the provisions of applicable state and federal banking laws and regulations, with Banner Bank being the resulting institution or surviving bank (the “Surviving Bank”). The Bank Merger shall have the effects as set forth under applicable state and federal banking laws and regulations and the Boards of Directors of the Parties shall approve, and shall cause the boards of directors of Siuslaw Bank and Banner Bank, respectively, to approve, a separate agreement/plan of merger (the “Bank Plan of Merger”) in substantially the form attached hereto as Exhibit C, and cause the Bank Plan of Merger to be executed and delivered as soon as practicable following the date of execution of this Agreement. In addition, Siuslaw shall cause Siuslaw Bank, and Banner shall cause Banner Bank, to execute and file in accordance with applicable state and federal banking laws and regulations such articles of merger, corporate resolutions, and/or other documents and certificates as are necessary to make the Bank Merger effective (the “Bank Merger Certificates”).

1.8 Additional Actions. If, at any time after the Effective Time, the Surviving Company shall consider that any further assignments or assurances in law or any other acts are necessary or desirable to (i) vest, perfect or confirm, of record or otherwise, in the Surviving Company its right,

title or interest in, to or under any of the rights, properties or assets of Siuslaw acquired or to be acquired by the Surviving Company as a result of, or in connection with, the Merger, or (ii) otherwise carry out the purposes of this Agreement, Siuslaw, and its proper officers and directors, shall be deemed to have granted to the Surviving Company an irrevocable power of attorney to execute and deliver all such proper deeds, assignments and assurances in law and to do all acts necessary or proper to vest, perfect or confirm title to and possession of such rights, properties or assets in the Surviving Company and otherwise to carry out the purposes of this Agreement, and the proper officers and directors of the Surviving Company are fully authorized in the name of the Surviving Company or otherwise to take any and all such action without limitation except as otherwise required by applicable law.

ARTICLE II

DELIVERY OF MERGER CONSIDERATION

2.1 Exchange Agent. Prior to the Effective Time, Banner shall appoint an unrelated bank or trust company reasonably acceptable to Siuslaw, or Banner's transfer agent, pursuant to an agreement (the “Exchange Agent Agreement”) to act as exchange agent (the “Exchange Agent”) hereunder.

2.2 Deposit of Merger Consideration. At or prior to the Effective Time, Banner shall (i) deposit with the Exchange Agent, or authorize the Exchange Agent to issue, an aggregate number of shares of Banner Common Stock equal to the stock portion of the aggregate Merger Consideration and (ii) deposit, or cause to be deposited with, the Exchange Agent, the cash portion of the aggregate Merger Consideration plus, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.3(f) (together, the “Exchange Fund”) and Banner shall instruct the Exchange Agent to timely deliver the Merger Consideration.

2.3 Delivery of Merger Consideration.

(a) As soon as reasonably practicable after the Effective Time (and in any event within ten (10) days thereafter), and subject to the receipt by the Exchange Agent of a list of Siuslaw’s shareholders in a format that is reasonably acceptable to the Exchange Agent, the Exchange Agent shall mail to each holder of a Certificate, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu of such Certificate) to the Exchange Agent) substantially in the form prescribed by the Exchange Agent Agreement (the “Letter of Transmittal”) and (ii) instructions for use in surrendering each Certificate in exchange for the Merger Consideration, any cash in lieu of a fractional share of Banner Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to Section 2.3(c).

(b) As soon as reasonably practicable after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, such holder of Siuslaw Common Stock will be entitled to receive the Merger Consideration, any cash in lieu of a fractional share of Banner Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled pursuant to Section 2.3(c), in respect of the shares of Siuslaw Common Stock represented by such holder’s Certificate or Certificates. Until so surrendered, each Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration, any cash in lieu of a fractional share of Banner Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate in

accordance with, and any dividends or distributions to which such holder is entitled pursuant to, this Article II.

(c) No dividends or other distributions with respect to Banner Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Banner Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive, without interest, and in addition to the other amounts set forth herein, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Banner Common Stock represented by such Certificate and not paid and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to whole shares of Banner Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Banner Common Stock issuable with respect to such Certificate.

(d) In the event of a transfer of ownership of a Certificate representing Siuslaw Common Stock prior to the Effective Time that is not registered in the stock transfer records of Siuslaw, the Merger Consideration, any cash in lieu of a fractional share of Banner Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled, shall be issued or paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such Siuslaw Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes (as defined in Section 3.10(b)) required by reason of the payment or issuance to a person other than the registered holder of the Certificate or establish to the satisfaction of Banner that the Tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) six months after the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, Banner) shall be entitled to deduct and withhold from the cash portion of the Merger Consideration and any cash in lieu of a fractional share of Banner Common Stock otherwise payable pursuant to this Agreement to any holder of Siuslaw Common Stock such amounts as the Exchange Agent or Banner, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign tax law, with respect to the making of such payment. To the extent amounts are so withheld by the Exchange Agent or Banner, as the case may be, and timely paid over to the appropriate Governmental Entity (as defined in Section 3.4), such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Siuslaw Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Banner, as the case may be.

(e) After the Effective Time, there shall be no transfers on the stock transfer books of Siuslaw of the shares of Siuslaw Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of Siuslaw Common Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration, any cash in lieu of fractional shares of Banner Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled, in accordance with the procedures set forth in this Article II.

(f) Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of Banner Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to Banner Common Stock shall be payable on or with respect to any fractional share, and such fractional share interest shall not entitle the owner thereof to vote or to any other rights of a shareholder of Banner. In lieu of the issuance of any such fractional share, Banner shall pay to each former shareholder of Siuslaw who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the Banner Average Closing Price by (ii) the fraction of a share (after taking into account all shares of Siuslaw Common Stock held by such holder at the Effective Time and rounded to the nearest one ten thousandth when expressed in decimal form) of Banner Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.4(b). For purposes of this Agreement, the terms “Banner Average Closing Price” means the average of the volume weighted closing price (rounded to the nearest one ten thousandth) of Banner Common Stock on the NASDAQ Global Select Market (“Nasdaq”) for the ten (10) trading days immediately preceding the fifth (5th) day prior to the Closing Date (as defined in Section 9.1).

(g) Any portion of the Exchange Fund that remains unclaimed by the shareholders of Siuslaw at the expiration of six months after the Effective Time shall be paid to Banner. In such event, any former shareholders of Siuslaw who have not theretofore complied with this Article II shall thereafter look only to Banner with respect to the Merger Consideration, any cash in lieu of any fractional share interest and any unpaid dividends and distributions on the Banner Common Stock deliverable in respect of the shares represented by a Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Banner, Siuslaw, the Surviving Company, the Exchange Agent or any other person shall be liable to any former holder of shares of Siuslaw Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Banner or the Exchange Agent, the posting by such person of a bond in such amount as Banner may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, any cash in lieu of any fractional share interest and any dividends and distributions to which such person is entitled in respect thereof pursuant to this Agreement.

ARTICLE III

Except as disclosed in the disclosure schedule delivered by Siuslaw to Banner concurrently herewith (the “Siuslaw Disclosure Schedule”); provided, that (a) no such item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (b) the mere inclusion of an item in the Siuslaw Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by Siuslaw that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect (as defined in Section 3.1(a)) and (c) any disclosures made with respect to a section of Article III shall be deemed to qualify (i) any

other section of Article III specifically referenced or cross-referenced and (ii) other sections of Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections, Siuslaw hereby represents and warrants to Banner as follows:

3.1 Corporate Organization.

(a) Siuslaw is a corporation duly organized and validly existing under the laws of the State of Oregon, and is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). Siuslaw has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted. Siuslaw is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siuslaw. As used in this Agreement, the term “Material Adverse Effect” means, with respect to Banner, Siuslaw or the Surviving Company, as the case may be, a material adverse effect on (i) the business, properties, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in United States generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally, (D) public disclosure of the transactions contemplated hereby or actions or inactions expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby, or (E) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections, but not, in either case, including the underlying causes thereof; except, with respect to subclauses (A), (B), or (C), to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate), or (ii) the ability of such party or its banking Subsidiary to timely consummate the transactions contemplated hereby. As used in this Agreement, the word “Subsidiary” when used with respect to any party, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, which is consolidated with such party for financial reporting purposes. True and complete copies of the articles of incorporation of Siuslaw (the “Siuslaw Charter”) and the bylaws of Siuslaw (the “Siuslaw Bylaws”), as in effect as of the date of this Agreement, have previously been made available by Siuslaw to Banner.

(b) Each Subsidiary of Siuslaw (a “Siuslaw Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly qualified to do business and, where such concept is recognized under applicable law, is in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership or leasing of property or the conduct of its business requires it to be so qualified and in which the failure to be so qualified would reasonably be expected to have a Material Adverse Effect on Siuslaw and (iii) has all requisite power and authority to own or lease its properties and assets and to carry on its business as now

conducted. There are no restrictions on the ability of any Subsidiary of Siuslaw to pay dividends or distributions except for statutory restrictions on dividends or distributions generally applicable to all entities of the same type and, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities. The deposit accounts of Siuslaw Bank are insured by the Federal Deposit Insurance Corporation (“FDIC”) through the Deposit Insurance Fund to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened. Section 3.1(b) of the Siuslaw Disclosure Schedule sets forth a true and complete list of all Subsidiaries of Siuslaw as of the date hereof. Neither Siuslaw nor any of its Subsidiaries owns any equity or profit-and-loss interest in any business enterprise, corporation, partnership or joint venture, limited liability company, association, joint-stock company, business trust or unincorporated organization, other than a Subsidiary, readily marketable securities, securities held-to-maturity in its investment portfolio, and stock in the Federal Home Loan Bank of Seattle (the “FHLB”).

Except for the automatic conversion of outstanding Siuslaw Preferred Stock to Siuslaw Common Stock described above, there are no outstanding subscriptions, options, warrants, puts, calls, rights, exchangeable or convertible securities or other commitments or agreements obligating Siuslaw to issue, transfer, sell, purchase, redeem or otherwise acquire, any such securities.

that are made available to similarly situated employees of Banner or its Subsidiaries (other than Siuslaw and its Subsidiaries), a Covered Employee's continued participation in employee benefit plans and compensation opportunities of Siuslaw and its Subsidiaries shall be deemed to satisfy the foregoing provisions of this sentence (it being understood that participation in the Banner Benefit Plans may commence at different times with respect to each Banner Benefit Plan).

(b) To the extent that a Covered Employee becomes eligible to participate in a Banner Benefit Plan, Banner shall cause such Banner Benefit Plan to (i) recognize full-time years of prior service from the date of most recent hire of such Covered Employee with Siuslaw or its Subsidiaries for purposes of eligibility, participation, vesting and, except under any plan that determines benefits on an actuarial basis, for benefit accrual, but only to the extent that such service was recognized immediately prior to the Effective Time under a comparable Siuslaw Benefit Plan in which such Covered Employee was eligible to participate immediately prior to the Effective Time; provided that such recognition of service shall not operate to duplicate any benefits of a Covered Employee with respect to the same period of service; and (ii) with respect to any Banner Benefit Plan that is a health, dental, vision plan or other welfare plan in which any Covered Employee is eligible to participate for the plan year in which such Covered Employee is first eligible to participate, Banner or its applicable Subsidiary shall use its commercially reasonable efforts to cause any pre-existing condition limitations or eligibility waiting periods under such Banner or Subsidiary plan to be waived with respect to such Covered Employee to the extent such condition was or would have been covered under the Siuslaw Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time.

(c) Prior to the Effective Time, and except as provided in Sections 6.5(d) and (e), Siuslaw shall take, and shall cause its Subsidiaries to take, all actions requested by Banner that may be necessary or appropriate to (i) cause one or more Siuslaw Benefits Plans to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any Siuslaw Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Siuslaw Benefit Plan for such period as may be requested by Banner, or (iv) facilitate the merger of any Siuslaw Benefit Plan into any employee benefit plan maintained by Banner or a Banner Subsidiary. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 6.5(c) shall be subject to Banner's reasonable prior review and approval, which shall not be unreasonably withheld.

(d) At the Effective Time or the effective time of the Bank Merger, Banner shall, or it shall cause Banner Bank to, assume and honor all salary continuation agreements, deferred compensation agreements and split-dollar agreements set forth under the heading “Non-Qualified Benefit Plans in Section 3.11(a) of the Siuslaw Disclosure Schedule and attached to Section 6.5(d) of the Siuslaw Disclosure Schedule. Notwithstanding Section 6.5(f), Banner shall not, and it shall not permit Banner Bank to, amend or terminate any of such salary continuation agreements or deferred compensation agreements in a manner that would alter or change the installment payout schedule thereof, except as required by law or in connection with termination of the non-qualified deferred compensation plans and agreements of Banner and Banner Bank. The provisions of this Section 6.5(d) shall survive the Effective Time, are intended for the benefit of and are enforceable by the individual parties to the above mentioned agreements, and shall be binding on all successors or assigns of Banner or Banner Bank, as applicable. In the event Banner or any of its successors or assigns (i) consolidates with or merges into any other person or entity and shall not be the continuing or surviving company or entity of such consolidation or merger, or (ii) transfers all or substantially

all of its properties and assets to one or more other persons or entities, then, and in each such case, proper provision shall be made so that the successors and assigns of Banner assume the obligations set forth in this Section 6.5(d).

(e) The Board of Directors of Siuslaw Bank has adopted a general severance plan for its full time employees (i.e., employees who are employed on average at least 30 hours of service per week pursuant to 26 U.S. Code §4980H), who are not executive officers and not otherwise entitled to contractual or other severance or change in control benefits, that provides for a severance benefit to each such employee in the amount of two (2) weeks base pay for each full year of full time employment with Siuslaw Bank from his or her most recent hire date with a maximum severance benefit of twenty six (26) weeks base pay, if and only if (i) such employee’s employment is involuntarily terminated by the employer without cause at the time of or within one (1) year following a change in control and (ii) such employee executes a release of all employment claims, which release shall be in a form that complies with Section 409A of the Code and is reasonably acceptable to the employer (the “Siuslaw Bank General Severance Plan”). At the Effective Time or at the effective time of the Bank Merger, Banner shall, or shall cause Banner Bank to, assume and honor the Siuslaw Bank General Severance Plan. Section 6.5(e) of the Siuslaw Disclosure Schedule sets forth the name of each individual entitled to contractual or other severance or change in control benefits from Siuslaw or any of its Subsidiaries (or their respective successors in interests) together with the dollar amount and payment terms of each monetary benefit and a detailed description of any non-monetary benefits.

(f) Except as provided in Section 6.5(d), nothing in this Section 6.5 shall be construed to limit the right of Banner or any of its Subsidiaries (including, following the Closing Date, any Siuslaw Subsidiary) to amend or terminate any Siuslaw Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor shall anything in this Section 6.5 be construed to require Banner or any of its Subsidiaries (including, following the Closing Date, any Siuslaw Subsidiary) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date.

6.6 Officers' and Directors' Insurance; Indemnification.

(a) For four (4) years from and after the Effective Time, Banner shall maintain officers' and directors' liability insurance covering the persons who are presently covered by Siuslaw's current officers' and directors' liability insurance policy with respect to actions, omissions, events, matters or circumstances occurring prior to the Effective Time, on terms which are at least substantially equivalent to the terms of said current policy, provided that it shall not be required to expend during the coverage period more than an amount equal to 200% of the annual premium most recently paid by Siuslaw (the “Insurance Amount”) to maintain or procure insurance coverage pursuant hereto, and further provided that if Banner is unable to maintain or obtain the insurance called for by this Section 6.6(a), Banner shall use commercially reasonable efforts to obtain as much comparable insurance as is available for the Insurance Amount. At Siuslaw’s option, Siuslaw may, in lieu of the foregoing, (or, if requested by Banner, Siuslaw shall) purchase prior to the Effective Time, a prepaid "tail" policy providing single limit equivalent coverage to that described in the preceding sentence for a premium cost not to exceed the Insurance Amount. The officers and directors of Siuslaw or its Subsidiaries may be required to make application and provide customary representations and warranties to Banner's insurance carrier for the purpose of obtaining such insurance.

(b) For four (4) years from and after the Effective Time, Banner shall indemnify and hold harmless each person who is now, or who has been at any time before the date of this Agreement, or

who becomes before the Effective Time, a director or officer of Siuslaw (each, a “Siuslaw Indemnified Party”) against all losses, claims, damages, costs, expenses (including reasonable attorneys’ fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of Banner, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding, investigation or other legal proceeding, whether civil, criminal, administrative or investigative or investigation (each, a “Claim”), in which a Siuslaw Indemnified Party is, or is threatened to be made, a party or witness arising out of the fact that such person is or was a director or officer of Siuslaw if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the fullest extent permitted under the Siuslaw Charter or Siuslaw Bylaws but limited to the extent permitted by applicable law including 12 USC 1828(k) and the regulations thereunder and Regulatory Agencies.

(c) In connection with the indemnification provided pursuant to Section 6.6(b), Banner (i) will advance expenses, promptly after statements therefor are received, to each such Siuslaw Indemnified Party to the fullest extent permitted by law and Governmental Entities (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such Siuslaw Indemnified Party or multiple Siuslaw Indemnified Parties, it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel), all such counsel shall be reasonably satisfactory to Banner and (ii) will cooperate in the defense of any such matter.

(d) This Section 6.6 shall survive the Effective Time, is intended to benefit each Siuslaw Indemnified Party (each of whom shall be entitled to enforce this Section against Banner), and shall be binding on all successors and assigns of Banner.

(e) In the event Banner or any of its successors or assigns (i) consolidates with or merges into any other person or entity and shall not be the continuing or surviving company or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to one or more other persons or entities, then, and in each such case, proper provision shall be made so that the successors and assigns of Banner assume the obligations set forth in this Section 6.6.

6.7 No Solicitation.

(a) Siuslaw agrees that, except as expressly permitted by Section 6.7(b), from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with Section 8.1, it will not, and will cause its Subsidiaries and its Subsidiaries’ officers, directors, and employees (the “Siuslaw Individuals”) not to, and will use its commercially reasonable efforts to cause Siuslaw and its Subsidiaries’ agents, advisors and controlled affiliates, accountants, legal counsel, and financial advisors (the “Siuslaw Representatives”) not to, initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any discussions or negotiations concerning, or provide any confidential or nonpublic information or data concerning its and/or its Subsidiaries business, properties or assets (“Siuslaw Confidential Information”) to, or have any discussions with, any person or entity relating to, any Acquisition Proposal. Siuslaw will immediately cease and cause to be terminated any activities, discussions or negotiations conducted

before the date of this Agreement with any persons or entities other than Banner with respect to any Acquisition Proposal and will use its commercially reasonable efforts, subject to applicable law, to enforce any confidentiality or similar agreement relating to such an Acquisition Proposal.

(b) Notwithstanding anything to the contrary in Section 6.7(a), at any time from the date of this Agreement and prior to obtaining the Siuslaw Shareholder Approval, in the event Siuslaw receives an unsolicited Acquisition Proposal and the Board of Directors of Siuslaw determines in good faith that such Acquisition Proposal constitutes a Superior Proposal (as defined below) or is reasonably likely to result in a Superior Proposal, Siuslaw may, and may permit its Subsidiaries and the Siuslaw Individuals and the Siuslaw Representatives to, (i) negotiate the terms of, and enter into, a confidentiality agreement with terms and conditions no less favorable to Siuslaw than the Confidentiality Agreement (an “Acceptable Confidentiality Agreement”), (ii) furnish or cause to be furnished Siuslaw Confidential Information to the person or entity making such Acquisition Proposal pursuant to an Acceptable Confidentiality Agreement, and (iii) negotiate and participate in such negotiations or discussions with the person or entity making such Acquisition Proposal concerning such Acquisition Proposal, if the Board of Directors of Siuslaw determines in good faith (following consultation with counsel) that failure to take such actions would result in a violation of its fiduciary duties under applicable law.

(c) The Board of Directors of Siuslaw shall not (nor shall any committee thereof) withdraw or modify, in a manner adverse to Banner, the Siuslaw Board Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify in any manner adverse to Banner the Siuslaw Board Recommendation (any such action, a “Change in Recommendation”). Notwithstanding the foregoing, the Board of Directors of Siuslaw (including any committee thereof) may, at any time prior to obtaining the Siuslaw Shareholder Approval, effect a Change in Recommendation in response to a bona fide written unsolicited Acquisition Proposal made after the date of this Agreement that the Board of Directors of Siuslaw determines in good faith (after consultation with counsel) constitutes a Superior Proposal; provided, however, that the Board of Directors of Siuslaw may not make a Change in Recommendation, or terminate this Agreement pursuant to Section 8.1(f), with respect to an Acquisition Proposal until it has given Banner at least four (4) business days, following Banner’s initial receipt of written notice that the Board of Directors of Siuslaw has determined that such Acquisition Proposal is a Superior Proposal and the reasons therefor, to respond to any such Acquisition Proposal and, taking into account any amendment or modification to this Agreement proposed by Banner, the Board of Directors of Siuslaw determines in good faith (after consultation with counsel) that such Acquisition Proposal continues to constitute a Superior Proposal.

(d) Siuslaw will promptly (and in any event within two (2) business days) advise Banner in writing following receipt of any Acquisition Proposal and the substance thereof (including the identity of the person or entity making such Acquisition Proposal), and will keep Banner apprised of any related developments, discussions and negotiations (including the terms and conditions, whether written or oral, of the Acquisition Proposal) on a current basis.

(e) As used in this Agreement, the following terms have the meanings set forth below:

“Acquisition Proposal” means a tender or exchange offer, proposal for a merger, consolidation or other business combination involving Siuslaw or Siuslaw Bank or any proposal or offer to acquire in any manner more than 24.99% of the voting power in, or more than 24.99% of the fair market value of the business, assets or deposits of, Siuslaw or Siuslaw Bank, other than the transactions contemplated by this Agreement.

“Superior Proposal” means a written Acquisition Proposal that the Board of Directors of Siuslaw concludes in good faith to be more favorable from a financial point of view to its shareholders than the Merger, (i) after receiving the advice of its financial advisors (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law; provided, however, that for purposes of the definition of “Superior Proposal,” the references to “more than 24.99%” in the definition of Acquisition Proposal shall be deemed to be references to “a majority”.

6.8 Notification of Certain Matters. Each of the Parties shall give prompt written notice to the other of any fact, event or circumstance known to it that (a) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (b) would cause or constitute a breach of any of its representations, warranties, covenants or agreements contained herein. Each of Siuslaw and Banner shall promptly inform the other in writing upon receiving notice of any claim, demand, cause of action or investigation by any Governmental Entity or third party against, or threatened against, it or any of its Subsidiaries or any of their respective assets, properties, or any of their respective directors, officers or employees in their individual capacities as such.

6.9 Correction of Information. Each of Siuslaw and Banner shall promptly correct and supplement in writing any information furnished under this Agreement so that such information shall be correct and complete in all material respects at all times, without taking into account any Material Adverse Effect qualification, and shall include all facts necessary to make such information correct and complete in all material respects at all times; provided, however, that in each case, such disclosure shall not be deemed to cure any breach of a representation, warranty, covenant or agreement or any failure of a condition under Article VII, or to otherwise limit or affect in any way the remedies available hereunder to any party receiving such notice.

6.10 System Integration. From and after the date hereof, Siuslaw shall cause Siuslaw Bank and its directors, officers and employees to, and shall make all commercially reasonable efforts (without undue disruption to either business) to cause Siuslaw Bank's data processing consultants and software providers to, cooperate and assist Siuslaw Bank and Banner Bank in connection with the planned electronic and systematic conversion of all applicable data of Siuslaw Bank to the Banner Bank system to occur after the Effective Time, including the training of Siuslaw Bank employees, without undue disruption to Siuslaw Bank's business, during normal business hours and at the expense of Banner or Banner Bank (not to include Siuslaw Bank's employee payroll).

6.11 Coordination; Integration. Subject to applicable law and regulation, during the period from the date hereof until the Effective Time, Siuslaw shall cause the Chief Executive Officer and Chief Financial Officer of Siuslaw Bank to assist and confer with the officers of Banner Bank, on a weekly basis, relating to the development, coordination and implementation of the post-Merger operating and integration plans of Banner Bank, as the Surviving Bank in the Bank Merger.

6.12 Trust Preferred Securities. Upon the Effective Time, Banner shall assume the due and punctual performance and observance of the covenants to be performed by Siuslaw under the Junior Subordinated Indenture, dated as of May 7, 2004, between Siuslaw and U.S. National Bank, as Trustee relating to $8 million in trust capital securities issued by Siuslaw Statutory Trust I (the “Trust Preferred Securities”), and the due and punctual payment of the principal of and premium, if any, and interest on the Trust Preferred Securities. In connection therewith, Banner and Siuslaw shall execute

and deliver any supplemental indentures or other documents, and the Parties shall provide any opinion of counsel to the trustee thereof, required to make such assumption effective.

6.13 Delivery of Agreements. Siuslaw shall cause the Voting Agreements and Non-Solicitation Agreements to be executed by its directors and executive officers and delivered to Banner prior to or simultaneously with the execution of this Agreement.

prohibiting or making illegal the consummation of the Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform any covenant or agreement in this Agreement required to be performed prior to the Effective Time;

(c) by either Siuslaw or Banner, if the Merger shall not have been consummated on or before March 31, 2015, unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth in this Agreement;

(d) by either Siuslaw or Banner (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties set forth in this Agreement on the part of Siuslaw, in the case of a termination by Banner, or Banner, in the case of a termination by Siuslaw, which breach, either individually or in the aggregate, would result in, if occurring or continuing on the Closing Date, the failure of the conditions set forth in Section 7.2 or 7.3, as the case may be, and which is not cured within twenty (20) days following written notice to the party committing such breach or by its nature or timing cannot be cured within such time period;

(e) by Banner if (i) the Board of Directors of Siuslaw (or any committee thereof) shall have failed to make the Siuslaw Board Recommendation or made a Change in Recommendation or (ii) Siuslaw shall have materially breached any of the provisions set forth in Section 6.7;

8.5 Amendment. This Agreement may be amended by the Parties, by action taken or authorized by their respective Boards of Directors, at any time before or after Siuslaw Shareholder Approval; provided, however, that after Siuslaw Shareholder Approval, there may not be, without further Siuslaw Shareholder Approval, any amendment of this Agreement that (i) alters in any manner the amount or form of the Merger Consideration to be received by Siuslaw shareholders; (ii) alters the tax treatment of the Merger or the tax consequences to Siuslaw shareholders or any party to this Agreement; or (iii) requires further approval under applicable law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

8.6 Extension; Waiver. At any time prior to the Effective Time, the Parties, by action taken or authorized by their respective Board of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or (c) waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on

strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

9.4 Interpretation. When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” All schedules and exhibits hereto shall be deemed part of this Agreement and included in any reference to this Agreement. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. If for any reason such court or regulatory agency determines that any provision, covenant or restriction is invalid, void or unenforceable, it is the express intention of the Parties that such provision, covenant or restriction be enforced to the maximum extent permitted.

9.5 Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile or other electronic means), all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other party, it being understood that each party need not sign the same counterpart.

9.6 Entire Agreement. This Agreement (including the documents and the instruments referred to in this Agreement), together with the Confidentiality Agreement, constitutes the entire agreement and supersedes all prior written, and prior or contemporaneous oral, agreements and understandings, between the Parties with respect to the subject matter of this Agreement, other than the Confidentiality Agreement.

9.7 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Washington applicable to contracts made and performed entirely within such state, without regard to any applicable conflicts of law principles or any other principle that could require the application of the application of the law of any other jurisdiction. The Parties hereto agree that any suit, action or proceeding brought by either party to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal or state court located in the State of Washington. Each of the Parties hereto submits to the jurisdiction of any such court in any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of, or in connection with, this Agreement or the transactions contemplated hereby and hereby irrevocably waives the benefit of jurisdiction derived from present or future domicile or otherwise in such action or proceeding. Each party hereto irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

9.8 Publicity. Neither Siuslaw nor Banner shall, and neither Siuslaw nor Banner shall permit any of its Subsidiaries to, issue or cause the publication of any press release or other public announcement with respect to, or otherwise make any public statement concerning, the transactions contemplated by this Agreement without the prior consent (which shall not be unreasonably withheld or delayed) of Banner, in the case of a proposed announcement or statement by Siuslaw, or Siuslaw, in the case of a proposed announcement or statement by Banner; provided, however, that either party may, without the prior consent of the other party (but after prior consultation with the other party to the extent practicable under the circumstances) issue or cause the publication of any press release or other public announcement to the extent required by law or by the rules and regulations of the Nasdaq.

9.9 Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by either of the Parties (whether by operation of law or otherwise) without the prior written consent of the other party (which shall not be unreasonably withheld or delayed). Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by each of the Parties and their respective successors and assigns. Except for Section 6.5(d) (which is intended to benefit the individual parties to the agreements referred to therein) and Section 6.6 (which is intended to benefit each Siuslaw Indemnified Party), or as otherwise specifically provided herein, this Agreement (including the documents and instruments referred to in this Agreement) is not intended to and does not confer upon any person other than the Parties hereto any rights or remedies under this Agreement.

9.10 Specific Performance; Time of the Essence. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the Parties shall be entitled specific performance of the terms hereof, without the necessity of demonstrating irreparable harm or posting of any bond or security, in addition to any other remedies to which they are entitled at law or equity. Time is of the essence for performance of the agreements, covenants and obligations of the Parties herein.

Banner and Siuslaw have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.
