WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code;
 
WHEREAS, the individuals and entities listed on Section 1.1 of the FIBK Disclosure Schedule (the “Scott Family Shareholders”) are supportive of this Agreement and the transactions contemplated hereby, including the Merger, and have determined that it is in their best interests to provide for their collective support for this Agreement and such transactions and, concurrently with the execution of this Agreement, are entering into a support agreement (the “Support Agreement”), pursuant to which, among other things, each of the Scott Family Shareholders is agreeing, subject to the terms of the Support Agreement, to vote all shares of FIBK Common Stock owned by such holders in favor of the approval and adoption of this Agreement and the FIBK Articles Amendment, and the Support Agreement is further a condition and inducement for GWB and FIBK to enter into this Agreement;

WHEREAS, 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 herein, and intending to be legally bound hereby, the parties agree as follows:
 
ARTICLE I
         
THE MERGER
 
1.1          The Merger.  Subject to the terms and conditions of this Agreement, in accordance with the Delaware General Corporation Law (the “DGCL”) and the Montana Business Corporation Act (the “MBCA”), at the Effective Time, GWB shall merge with and into FIBK (the “Merger”), with FIBK surviving the Merger (hereinafter sometimes referred to in such capacity as the “Surviving Entity”).  The Surviving Entity shall continue its corporate existence under the laws of the State of Montana.  Upon consummation of the Merger, the separate corporate existence of GWB shall terminate.
 
1.2          Closing.  Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., New York City time, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by GWB and FIBK.  The date on which the Closing occurs is referred to as the “Closing Date.”
 
1.3          Effective Time.  On or (if agreed by GWB and FIBK) prior to the Closing Date, FIBK and GWB, respectively, shall cause to be filed articles of merger with the Secretary of State of the State of Montana (the “Montana Secretary”) and a certificate of merger with the Secretary of State of the State of Delaware (the “Delaware Secretary”) (collectively, the “Articles of Merger”).  The Merger shall become effective at such time as specified in the Articles of Merger in accordance with the relevant provisions of the MBCA and the DGCL, or at such other time as shall be provided by applicable law (such time hereinafter referred to as the “Effective Time”).
 
1.4          Effects of the Merger.  At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the MBCA and the DGCL.
 
1.5          Conversion of GWB Common Stock.  At the Effective Time, by virtue of the Merger and without any action on the part of FIBK, GWB or the holder of any securities of FIBK or GWB:
 
2

(a)          Subject to Section 2.2(e), each share of the common stock, par value $0.01 per share, of GWB issued and outstanding immediately prior to the Effective Time (the “GWB Common Stock”), except for shares of GWB Common Stock owned by GWB or FIBK (in each case other than shares of GWB Common Stock (i) 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 or (ii) held, directly or indirectly, by GWB or FIBK in respect of debts previously contracted), shall be converted into the right to receive 0.8425 shares (the “Exchange Ratio” and such shares the “Merger Consideration”) of Class A common stock, no par value, of FIBK (the “FIBK Class A Common Stock”).
 
(b)          All of the shares of GWB Common Stock converted into the right to receive the Merger Consideration pursuant to this Section 1.5 shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate,” it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book‑entry account statements relating to the ownership of shares of GWB Common Stock) previously representing any such shares of GWB Common Stock shall thereafter represent only the right to receive (i) the number of whole shares of FIBK Class A Common Stock which such shares of GWB Common Stock have been converted into the right to receive pursuant to this Section 1.5, (ii) cash in lieu of fractional shares which the shares of GWB Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2, in each case, without any interest thereon.  If, prior to the Effective Time, the outstanding shares of FIBK Class A Common Stock or GWB 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 or reverse stock split, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give FIBK and the holders of GWB Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided that nothing contained in this sentence shall be construed to permit GWB or FIBK to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.
 
(c)          Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of GWB Common Stock that are owned by GWB or FIBK (in each case other than shares of GWB Common Stock (i) 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 or (ii) held, directly or indirectly, by GWB or FIBK in respect of debts previously contracted) shall be cancelled and shall cease to exist and no FIBK Class A Common Stock or other consideration shall be delivered in exchange therefor.
 
1.6          FIBK Stock.  At and after the Effective Time, each share of (a) FIBK Class A Common Stock and (b) Class B common stock, no par value, of FIBK (the “FIBK Class B Common Stock” and, together with the FIBK Class A Common Stock, the “FIBK Common Stock”), issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Entity and shall not be affected by the Merger.
 
3

1.7          Treatment of GWB Equity Awards.
 
(a)          At the Effective Time, each time-vesting restricted stock unit award in respect of a share of GWB Common Stock (each a “GWB RSU Award”) granted under the GWB 2014 Omnibus Incentive Compensation Plan, the GWB 2014 Non-Employee Director Plan or the GWB Executive Incentive Compensation Plan (each a “GWB Stock Plan”) that is outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any required action on the part of GWB or any holder of such GWB RSU Award, fully vest and be cancelled and converted automatically into the right to receive the Merger Consideration, as if such GWB RSU Award had been settled in shares of GWB Common Stock immediately prior to the Effective Time (the “GWB RSU Award Consideration”).
 
(b)          At the Effective Time, each restricted stock unit award in respect of a share of GWB Common Stock that is earned or vests based in whole or in part on the achievement of performance metrics (each a “GWB PSU Award,” and together with the GWB RSU Awards, the “GWB Equity Awards”) granted under a GWB Stock Plan that is outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any required action on the part of GWB or any holder of such GWB PSU Award, vest at the greater of the target or actual level of performance, as determined by GWB Board of Directors or a committee thereof prior to the Effective Time (the “Earned PSUs”), and be cancelled and converted automatically into the right to receive the Merger Consideration, as if such Earned PSUs had been settled in shares of GWB Common Stock immediately prior to the Effective Time (the “GWB PSU Award Consideration”).  For the avoidance of doubt, any portion of the GWB PSU Awards that are not Earned PSUs shall be forfeited and cancelled at the Effective Time for no consideration.
 
(c)          Prior to the Effective Time, GWB, the Board of Directors of GWB and its compensation committee, as applicable, shall adopt any resolutions and take any actions that are reasonably necessary or appropriate to effectuate the provisions of Section 1.7(a) and Section 1.7(b).
 
(d)          The GWB RSU Award Consideration and the GWB PSU Award Consideration amounts shall be delivered as soon as reasonably practicable following the Closing Date and in no event no later than two (2) business days following the Closing Date, and shall be reduced by any withholding Taxes required to be paid by or collected on behalf of the recipients of the GWB RSU Award Consideration and the GWB PSU Award Consideration (which withholding Taxes shall be satisfied by retaining a number of shares of FIBK Class A Common Stock having a fair market value (determined by reference to the closing price of a share of FIBK Class A Common Stock on the Closing Date) equal to the minimum statutory amount required to be withheld).  Notwithstanding anything herein to the contrary, with respect to any GWB RSU Award or GWB PSU Award that constitutes nonqualified deferred compensation subject to Section 409A of the Code and that GWB determines prior to the Effective Time is not eligible to be terminated in accordance with Treasury Regulation Section 1.409A-3(j)(4)(ix)(B), the payment or provision of the GWB RSU Award Consideration and the GWB PSU Award Consideration will be made at the earliest time permitted under the applicable GWB Equity Award that will not trigger a Tax or penalty under Section 409A of the Code.
 
4

1.8          Certificate of Incorporation of Surviving Entity.  At the Effective Time, the articles of incorporation of FIBK, as amended as set forth in Exhibit A (such amendment, the “FIBK Articles Amendment”), shall be the articles of incorporation of the Surviving Entity until thereafter amended in accordance with applicable law.
 
1.9          Bylaws of Surviving Entity.  At the Effective Time, the bylaws of FIBK, as amended as set forth in Exhibit B (such amendment, the “FIBK Bylaws Amendment”), shall be the bylaws of the Surviving Entity until thereafter amended in accordance with applicable law.
 
1.10          Tax Consequences.  It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.
 
1.11          Bank Merger.
 
(a)          Immediately following the Merger, Great Western Bank, a South Dakota state chartered bank and a wholly owned Subsidiary of GWB (“GWB Subsidiary Bank”), will merge with and into First Interstate Bank, a Montana-chartered bank and a wholly owned Subsidiary of FIBK (“FIBK Subsidiary Bank”) (the “Bank Merger”).  FIBK Subsidiary Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of GWB Subsidiary Bank shall cease.  Promptly after the date of this Agreement, GWB Subsidiary Bank and FIBK Subsidiary Bank shall enter into an agreement and plan of merger in substantially the form set forth in Exhibit C (the “Bank Merger Agreement”).  The Board of Directors of each of GWB Subsidiary Bank and FIBK Subsidiary Bank shall approve the Bank Merger Agreement, and each of GWB and FIBK shall approve the Bank Merger Agreement and the Bank Merger as the sole shareholder of GWB Subsidiary Bank and FIBK Subsidiary Bank, respectively, and GWB and FIBK shall, and shall cause GWB Subsidiary Bank and FIBK Subsidiary Bank, respectively, to, execute certificates or articles of merger and such other documents and certificates as are necessary to make the Bank Merger effective (“Bank Merger Certificates”) immediately following the Effective Time. The Bank Merger shall become effective at such time and date as specified in the Bank Merger Agreement in accordance with applicable law, or at such other time as shall be provided by applicable law.
 
(b)          It is intended that the Bank Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that the Bank Merger Agreement is intended to be and will be adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.

ARTICLE II    

EXCHANGE OF SHARES
 
2.1          FIBK to Make Consideration Available.  At or prior to the Effective Time, FIBK shall deposit, or shall cause to be deposited, with a bank or trust company mutually agreed upon by FIBK and GWB (the “Exchange Agent”), for exchange in accordance with this Article II for the benefit of the holders of Old Certificates, evidence in book-entry form representing shares of FIBK Class A Common Stock to be issued pursuant to Section 1.5, and any cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) and shares of FIBK Class A Common Stock to be issued pursuant to Section 1.5, together with any dividends or distributions with respect to shares of FIBK Class A Common Stock payable in accordance with Section 2.2(b), being referred to herein as the “Exchange Fund”).
 
2.2          Exchange of Shares.
 
(a)          As promptly as practicable after the Effective Time, but in no event later than five (5) days thereafter, the Surviving Entity shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of GWB Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive FIBK Class A Common Stock pursuant to Section 1.5(a), a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for the number of whole shares of FIBK Class A Common Stock and any cash in lieu of fractional shares which the shares of GWB Common Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b) (such materials and instructions to include customary provisions with respect to delivery of an “agent’s message” with respect to book-entry shares).  Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent (it being understood that no certificates shall be required to be delivered for shares of GWB Common Stock held in book-entry at the Effective Time), together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, (i) that number of whole shares of FIBK Class A Common Stock to which such holder of GWB Common Stock shall have become entitled pursuant to the provisions of Section 1.5(a) and (ii) a check representing the amount of (A) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II and (B) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled.  No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates.  Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of FIBK Class A Common Stock which the shares of GWB Common Stock represented by such Old Certificate have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.
 
(b)          No dividends or other distributions declared with respect to FIBK Class A Common Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II.  After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of FIBK Class A Common Stock that the shares of GWB Common Stock represented by such Old Certificate have been converted into the right to receive.
 
6

(c)          If any share of FIBK Class A Common Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of the shares of FIBK Class A Common Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.
 
(d)          After the Effective Time, there shall be no transfers on the stock transfer books of GWB of the shares of GWB Common Stock that were issued and outstanding immediately prior to the Effective Time.  If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for shares of FIBK Class A Common Stock and any cash in lieu of fractional shares as provided in this Article II.
 
(e)          Notwithstanding anything to the contrary contained herein, no fractional shares of FIBK Class A Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to FIBK Class A Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of FIBK.  In lieu of the issuance of any such fractional share, the Surviving Entity shall pay to each former holder of GWB Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of FIBK Class A Common Stock on NASDAQ as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the trading day immediately preceding the Closing Date (or, if not reported therein, in another authoritative source mutually agreed upon by FIBK and GWB) by (ii) the fraction of a share (after taking into account all shares of GWB Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of FIBK Class A Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5.  The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.
 
7

(f)          Any portion of the Exchange Fund that remains unclaimed by the stockholders of GWB for twelve (12) months after the Effective Time shall be paid to the Surviving Entity.  Any former holders of GWB Common Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of FIBK Class A Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the FIBK Class A Common Stock deliverable in respect of each former share of GWB Common Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon.  Notwithstanding the foregoing, none of FIBK, GWB, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of GWB Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.  Any amounts remaining unclaimed by former holders of shares of GWB Common Stock immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Entity shall, to the extent permitted by applicable law, become the property of the Surviving Entity, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

(g)          The Surviving Entity shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of FIBK Class A Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement to any holder of GWB Common Stock or GWB Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment or distribution under the Code or any provision of state, local or foreign Tax law.  To the extent that amounts are so deducted or withheld by the Surviving Entity or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of GWB Common Stock or GWB Equity Awards in respect of which the deduction and withholding was made by the Surviving Entity or the Exchange Agent, as the case may be.
 
(h)          In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by the Surviving Entity or the Exchange Agent, the posting by such person of a bond in such amount as the Surviving Entity or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of FIBK Class A Common Stock and any cash in lieu of fractional shares, as applicable, deliverable in respect thereof pursuant to this Agreement.

REPRESENTATIONS AND WARRANTIES OF GWB

Except (a) as disclosed in the disclosure schedule delivered by GWB to FIBK concurrently herewith (the “GWB Disclosure Schedule”); provided, that (i) 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, (ii) the mere inclusion of an item in the GWB Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by GWB that such item represents a material exception or fact, event or circumstance or that such item would reasonably be expected to have a Material Adverse Effect and (iii) any disclosures made with respect to a section of this Article III shall be deemed to qualify (1) any other section of this Article III specifically referenced or cross-referenced and (2) other sections of this 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 or (b) as disclosed in any GWB Reports filed by GWB since September 30, 2019, and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly non-specific or cautionary, predictive or forward-looking in nature), GWB hereby represents and warrants to FIBK as follows:
 
3.1          Corporate Organization.
 
(a)          GWB is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, and is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”).  GWB has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted.  GWB is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on GWB.  As used in this Agreement, the term “Material Adverse Effect” means, with respect to FIBK, GWB or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided 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 U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (B) changes, after the date hereof, in laws, rules or regulations (including the Pandemic Measures) 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 and not specifically relating to such party or its Subsidiaries (including any such changes arising out of the Pandemic or any Pandemic Measures), (D) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, floods or other natural disasters or from any outbreak of any disease or other public health event (including the Pandemic), (E) public disclosure or consummation of the transactions contemplated hereby or actions 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 (it being understood and agreed that this clause (E) shall not apply with respect to any representation or warranty that is intended to address the consequences of the execution, announcement or performance of this Agreement or the consummation of the Merger), or (F) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts, but not, in either case, including any underlying causes thereof; except, with respect to subclause (A), (B), (C) or (D), 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 to timely consummate the transactions contemplated hereby.  As used in this Agreement, the word “Pandemic” means any outbreaks, epidemics or pandemics relating to SARS-CoV-2 or COVID-19, or any evolutions or mutations thereof, or any other viruses (including influenza), and the governmental and other responses thereto; the word “Pandemic Measures” means any quarantine, “shelter in place”, “stay at home”, workforce reduction, social distancing, shut down, closure, sequester or other laws, directives, policies, guidelines or recommendations promulgated by any Governmental Entity, including the Centers for Disease Control and Prevention and the World Health Organization, in each case, in connection with or in response to the Pandemic; and the word “Subsidiary” when used with respect to any person, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, or person of which (x) such first person directly or indirectly owns or controls at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions or (y) such first person is or directly or indirectly has the power to appoint a general partner, manager or managing member or others performing similar functions.  True and complete copies of the certificate of incorporation of GWB (the “GWB Charter”) and the bylaws of GWB (the “GWB Bylaws”), in each case as in effect as of the date of this Agreement, have previously been made available by GWB to FIBK.

(b)          Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on GWB, each Subsidiary of GWB (a “GWB Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership, leasing or operation of property or the conduct of its business requires it to be so licensed or qualified or in good standing and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted.  There are no restrictions on the ability of GWB or any Subsidiary of GWB to pay dividends or distributions except, in the case of GWB or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities.  The deposit accounts of GWB Subsidiary Bank are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950) 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, to the knowledge of GWB, threatened.  Section 3.1(b) of the GWB Disclosure Schedule sets forth a true and complete list of all Subsidiaries of GWB as of the date hereof.  No Subsidiary of GWB is in violation of any of the provisions of the articles or certificate of incorporation or bylaws (or comparable organizational documents) of such Subsidiary of GWB.  There is no person whose results of operations, cash flows, changes in shareholders’ equity or financial position are consolidated in the financial statements of GWB other than the GWB Subsidiaries.

12

(b)          Neither the execution and delivery of this Agreement by GWB nor the consummation by GWB of the transactions contemplated hereby (including the Merger and the Bank Merger), nor compliance by GWB with any of the terms or provisions hereof, will (i) violate any provision of the GWB Charter or the GWB Bylaws or the articles or certificate of incorporation or bylaws (or similar organizational documents) of any GWB Subsidiary or (ii) assuming that the consents and approvals referred to in Section 3.4 are duly obtained, (x) violate any law, statute, code, ordinance, rule, regulation, judgment, order, writ, decree or injunction applicable to GWB or any of its Subsidiaries or any of their respective properties or assets or (y) violate, conflict with, result in a breach of any provision of or the loss of any benefit under, constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, result in the termination of or a right of termination or cancellation under, accelerate the performance required by, or result in the creation of any Lien upon any of the respective properties or assets of GWB or any of its Subsidiaries under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which GWB or any of its Subsidiaries is a party, or by which they or any of their respective properties or assets may be bound, except (in the case of clauses (x) and (y) above) for such violations, conflicts, breaches or defaults that, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on GWB.

(b)          Except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on GWB, neither GWB nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of GWB included in its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2021 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since June 30, 2021, or in connection with this Agreement and the transactions contemplated hereby.
 
(c)          The records, systems, controls, data and information of GWB and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership and direct control of GWB or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a Material Adverse Effect on GWB.  GWB (x) has implemented and maintains disclosure controls and procedures and internal controls over financial reporting (as defined in Rule 13a-15(e) and (f), respectively, of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to ensure that material information relating to GWB, including its Subsidiaries, is made known to the chief executive officer and the chief financial officer of GWB by others within those entities as appropriate to allow timely decisions regarding required disclosures and to make the certifications required by the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to GWB’s outside auditors and the audit committee of GWB’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to materially adversely affect GWB’s ability to record, process, summarize and report financial information, and (ii) any fraud that involves management or senior employees who have a significant role in GWB’s internal controls over financial reporting.  These disclosures were made in writing by management to GWB’s auditors and audit committee and true, correct and complete copies of such disclosures have been made available by GWB to FIBK.  Neither GWB nor its independent audit firm has identified any unremediated material weakness in internal controls over financial reporting or disclosure controls and procedures.  GWB has no reason to believe that its outside auditors and its chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act, without qualification, when next due.

(i)          There are no pending or threatened claims (other than claims for benefits in the ordinary course), actions, suits, audits, lawsuits or arbitrations which have been asserted or instituted, and, to GWB’s knowledge, no set of circumstances exists which may reasonably give rise to a claim, action, suit, audit, lawsuit or arbitration against the GWB Benefit Plans, any fiduciaries thereof with respect to their duties to the GWB Benefit Plans or the assets of any of the trusts under any of the GWB Benefit Plans that would reasonably be expected to result in any material liability of GWB or any of its Subsidiaries to the PBGC, the IRS, the DOL, any Multiemployer Plan, a Multiple Employer Plan, any participant in a GWB Benefit Plan, or any other party.

(k)          Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (either alone or in conjunction with any other event) (i) result in, cause the vesting, exercisability or delivery of, or increase in the amount or value of, any payment, right or other benefit to any current or former employee, officer, director, or other service provider of GWB or any of its Subsidiaries, (ii) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under any GWB Benefit Plan, or (iii) result in any limitation on the right of GWB or any of its Subsidiaries to amend, merge, terminate or receive a reversion of assets from any GWB Benefit Plan or related trust.
 
(l)          The transactions contemplated by this Agreement will not cause or require GWB or any of its affiliates to establish or make any contribution to a rabbi trust or similar funding vehicle.

58

(c)          Each party shall use its reasonable best efforts to resolve any objection that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby.  Notwithstanding the foregoing, nothing contained herein shall be deemed to require FIBK or GWB or any of their respective Subsidiaries, and neither FIBK nor GWB nor any of their respective Subsidiaries shall be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, orders, approvals, waivers, non-objections and authorizations of Governmental Entities that would reasonably be expected to have a material adverse effect on the business, properties, assets, liabilities, results of operations or financial condition of the Surviving Entity and its Subsidiaries, taken as a whole, after giving effect to the Merger (measured on a scale relative to FIBK and its Subsidiaries, taken as a whole) (a “Materially Burdensome Regulatory Condition”).
 
(d)          FIBK and GWB shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders or stockholders, as applicable, and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of FIBK, GWB or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger and the Bank Merger and the other transactions contemplated by this Agreement.
 
(e)          FIBK and GWB shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained, or that the receipt of any such approval will be materially delayed.
 
6.2          Access to Information; Confidentiality.
 
(a)          Upon reasonable notice and subject to applicable laws, each of GWB and FIBK, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the Representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, provided that such investigation or requests shall not interfere unnecessarily with normal operations of the party, and each shall cooperate with the other party in preparing to execute after the Effective Time the conversion or consolidation of systems and business operations generally, and, during such period, each of GWB and FIBK shall, and shall cause its Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents that GWB or FIBK, as the case may be, is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request.  Neither FIBK nor GWB nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of FIBK’s or GWB’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement.  The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.
 
59

(b)          Each of GWB and FIBK shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or Representatives pursuant to this Agreement in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated May 5, 2021, between FIBK and GWB (the “Confidentiality Agreement”).
 
(c)          No investigation by either of the parties or their respective Representatives shall affect or be deemed to modify or waive the representations, warranties, covenants and agreements of the other set forth herein.  Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time.  Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.
 
60

6.3          Stockholder and Shareholder Approvals.  Each of FIBK and GWB shall call, give notice of, establish a record date for, convene and hold a meeting of its shareholders and stockholders, respectively (the “FIBK Meeting” and the “GWB Meeting,” respectively) to be held as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining (i) in the case of GWB, the Requisite GWB Vote, and in the case of FIBK, the Requisite FIBK Vote, and (ii) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of shareholders or stockholders, as applicable, in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of GWB and FIBK shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date.  Subject to the remainder of this Section 6.3, each of FIBK and GWB and their respective Boards of Directors shall use its reasonable best efforts to obtain from the shareholders of FIBK and the stockholders of GWB, as applicable, the Requisite FIBK Vote and the Requisite GWB Vote, as applicable, including by communicating to the shareholders of FIBK and the stockholders of GWB, as applicable, its recommendation (and including such recommendation in the Joint Proxy Statement) that, in the case of FIBK, the shareholders of FIBK adopt and approve this Agreement and the transactions contemplated hereby (including the issuance of shares of FIBK Class A Common Stock pursuant to this Agreement) and approve the FIBK Articles Amendment (the “FIBK Board Recommendation”), and, in the case of GWB, the stockholders of GWB adopt and approve this Agreement and the transactions contemplated hereby (the “GWB Board Recommendation”).  Subject to the remainder of this Section 6.3, each of FIBK and GWB and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the FIBK Board Recommendation, in the case of FIBK, or the GWB Board Recommendation, in the case of GWB, (ii) fail to make the FIBK Board Recommendation, in the case of FIBK, or the GWB Board Recommendation, in the case of GWB, in the Joint Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the FIBK Board Recommendation, in the case of FIBK, or the GWB Board Recommendation, in the case of GWB, in each case within ten (10) business days (or such fewer number of days as remains prior to the FIBK Meeting or the GWB Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing a “Recommendation Change”).  However, subject to Section 8.1 and Section 8.2, if the Board of Directors of FIBK or GWB, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the FIBK Board Recommendation or the GWB Board Recommendation, as applicable, such Board of Directors may, in the case of FIBK, prior to the receipt of the Requisite FIBK Vote, and in the case of GWB, prior to the receipt of the Requisite GWB Vote, effect a Recommendation Change, including by submitting this Agreement to its shareholders or stockholders, respectively, without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for such Recommendation Change to its shareholders or stockholders, as applicable, in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that such Board of Directors may not take any actions under this sentence unless it (A) gives the other party at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the FIBK Board Recommendation or GWB Board Recommendation, as the case may be.  Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3.  Neither FIBK nor GWB shall adjourn or postpone the FIBK Meeting or the GWB Meeting, as the case may be, except that FIBK or GWB (1) shall be permitted to adjourn or postpone the FIBK Meeting or the GWB Meeting, as the case may be, to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure which the Board of Directors of FIBK or the Board of Directors of GWB, as the case may be, has determined in good faith after consultation with outside counsel is necessary under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by such party’s shareholders or stockholders, as applicable, prior to the FIBK Meeting or the GWB Meeting, as the case may be and (2) shall adjourn or postpone the FIBK Meeting or the GWB Meeting, as the case may be, up to two times, if, as of the time for which such meeting is originally scheduled there are insufficient shares of FIBK Common Stock or GWB Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting GWB or FIBK, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite GWB Vote or the Requisite FIBK Vote; provided that, without the prior written consent of the other party, neither FIBK nor GWB shall adjourn or postpone the FIBK Meeting or the GWB Meeting, as the case may be, under this clause (2) for more than five (5) business days in the case of any individual adjournment or postponement or more than twenty (20) business days in the aggregate.  Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, (x) the FIBK Meeting shall be convened and this Agreement shall be submitted to the shareholders of FIBK at the FIBK Meeting and (y) the GWB Meeting shall be convened and this Agreement shall be submitted to the stockholders of GWB at the GWB Meeting, and nothing contained herein shall be deemed to relieve either FIBK or GWB of such obligation.
 
61

6.4          Legal Conditions to Merger.  Subject in all respects to Section 6.1 of this Agreement, each of FIBK and GWB shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by GWB or FIBK or any of their respective Subsidiaries in connection with the Merger and the Bank Merger and the other transactions contemplated by this Agreement.

(a)          For a period commencing at the Effective Time and ending on the one year anniversary of the Effective Time, FIBK shall provide, or cause to be provided, to each individual who is employed by GWB or any of its Subsidiaries as of immediately prior to the Effective Time and who continues to be actively employed by the Surviving Entity (or any affiliate thereof) during such period (a “Continuing Employee”), with (i) a base salary or base wage rate that is no less than the base salary or base wage rate in effect for such Continuing Employee as of immediately prior to the Effective Time, (ii) short-term incentive compensation opportunities, long-term incentive compensation opportunities and other compensation and employee benefits (in each case of clause (i) and (ii) of this Section 6.6(a), excluding defined benefit pension, retiree medical, change in control and severance benefits) that, in each case, are no less favorable than those provided to similarly situated employees of FIBK and its Subsidiaries, and (iii) to any Continuing Employee who experiences an involuntary termination of employment without cause (or other severance-qualifying termination) during such period, severance benefits pursuant to FIBK’s severance policy (the terms of which are described in Section 6.6(a) of the FIBK Disclosure Schedule), and which shall apply to Continuing Employees in a manner no less favorable than as applicable to similarly situated employees of FIBK and its Subsidiaries. Nothing in this Section 6.6(a) is intended to limit FIBK or any of its Subsidiaries from taking or continuing to take reasonable actions in response to the COVID-19 related stresses on FIBK after the Closing Date, including reductions in force, furloughs, temporary layoffs, or reduced hours, pay or benefits; provided that no such actions shall disproportionately adversely affect the Continuing Employees when compared to similarly situated FIBK employees.

(b)          With respect to any FIBK Benefit Plans in which any Continuing Employees first become eligible to participate on or after the Closing Date, FIBK or the  Surviving Entity shall:  (i) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any such FIBK Benefit Plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous GWB Benefit Plan immediately prior to the Closing Date, (ii) provide each such Continuing Employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the Closing Date (or, if later, prior to the time such employee commenced participation in such FIBK Benefit Plan) under such FIBK Benefit Plan (to the same extent that such credit was given under the analogous GWB Benefit Plan) in satisfying any applicable deductible or out-of-pocket requirements under any such FIBK Benefit Plans, and (iii) recognize all service of such employees with GWB and its respective Subsidiaries, for all purposes to the same extent that such service was taken into account under the analogous GWB Benefit Plan prior to the Closing Date; provided that the foregoing service recognition shall not apply to the extent it would result in duplication of benefits for the same period of services, for purposes of benefit accrual under any FIBK Benefit Plan that is a defined benefit pension plan, for purposes of any FIBK Benefit Plan that provides retiree welfare benefits, or to any FIBK Benefit Plan that is a frozen plan, either with respect to level of benefits or participation, or provides grandfathered benefits.
 
(c)          If directed in writing by FIBK at least ten (10) business days prior to the Effective Time, GWB shall terminate any GWB Qualified Plan effective as of, and contingent upon, the Effective Time. In connection with the termination of such plan, FIBK shall take any and all actions as may be required to permit each affected GWB employee to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code, including all participant loans) in cash or notes (in the case of participant loans) in an amount equal to the eligible rollover distribution portion of the account balance distributed to each such affected employee from such plan to an “eligible retirement plan” (within the meaning of Section 401(a)(31) of the Code) of FIBK or any of its Subsidiaries (a “FIBK Qualified Plan”).  If a GWB Qualified Plan is terminated as described herein, the affected employees shall be eligible immediately upon the Closing Date to commence participation in a FIBK Qualified Plan.
 
(d)          GWB and FIBK shall cooperate in good faith in structuring any payments or benefits that may be made in connection with the transactions contemplated hereby, or preparing any reasonable compensation analysis (including valuing applicable noncompetition covenants), to mitigate any negative tax consequences to GWB, FIBK or the applicable service provider that may arise due to any such payments or benefits being subject to Sections 280G and 4999 of the Code.
 
63

(e)          Nothing in this Agreement shall confer upon any employee, officer, director or consultant of GWB or any of its Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Entity, GWB, FIBK or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, GWB, FIBK or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of GWB or any of its Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause.  Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any GWB Benefit Plan, FIBK Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity or any of its Subsidiaries or affiliates to amend, modify or terminate any particular Employee Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time.  Without limiting the generality of Section 9.11, except as set forth in Section 6.7, nothing in this Agreement, express or implied, is intended to or shall confer upon any person not a party to this Agreement, including any current or former employee, officer, director or consultant of FIBK or GWB or any of their Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.
 
6.7          Indemnification; Directors’ and Officers’ Insurance.
 
(a)          From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless and shall advance expenses as incurred, in each case to the extent (subject to applicable law) such persons are indemnified as of the date of this Agreement by GWB pursuant to the GWB Charter, the GWB Bylaws, the governing or organizational documents of any Subsidiary of GWB and any indemnification agreements in existence as of the date hereof and disclosed in Section 6.7(a) of the GWB Disclosure Schedule, each present and former director or officer of GWB and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “GWB Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of the fact that such person is or was a director or officer of GWB or any of its Subsidiaries and pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, any GWB Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such GWB Indemnified Party is not entitled to indemnification.
 
(b)          For a period of six (6) years after the Effective Time, the Surviving Entity shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by GWB (provided, that the Surviving Entity may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims arising from facts or events which occurred at or before the Effective Time; provided that the Surviving Entity shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the current annual premium paid as of the date hereof by GWB for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Entity shall cause to be maintained policies of insurance which, in the Surviving Entity’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap.  In lieu of the foregoing, FIBK or GWB, in consultation with, but only upon the consent of FIBK, may (and at the request of FIBK, GWB shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy under GWB’s existing directors’ and officers’ insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.
 
64

(c)          The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each GWB Indemnified Party and his or her heirs and representatives.  If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case, the Surviving Entity will cause proper provision to be made so that the successors and assigns of the Surviving Entity will expressly assume the obligations set forth in this Section 6.7.
 
6.8          Additional Agreements.  In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of FIBK, on the one hand, and a Subsidiary of GWB, on the other hand) or to vest the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take, or cause to be taken, all such necessary action as may be reasonably requested by FIBK.
 
6.9          Advice of Changes.  FIBK and GWB shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on it or (ii) that it believes would or would reasonably be expected to cause or constitute a material breach of any of its representations, warranties, obligations, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.9 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.
 
6.10         Dividends.  After the date of this Agreement, each of FIBK and GWB shall coordinate with the other the declaration of any dividends in respect of FIBK Common Stock and GWB Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of GWB Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of GWB Common Stock and any shares of FIBK Class A Common Stock any such holder receives in exchange therefor in the Merger.
 
65

6.11        Shareholder Litigation.  Each party shall give the other party prompt notice of any shareholder litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement, and GWB shall give FIBK the opportunity to participate (at FIBK’s expense) in the defense or settlement of any such litigation.  Each party shall give the other the right to review and comment on all filings or responses to be made by such party in connection with any such litigation, and will in good faith take such comments into   account. GWB shall not agree to settle any such litigation without FIBK’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that FIBK shall not be obligated to consent to any settlement which does not include a full release of FIBK and its affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its affiliates.
 
6.12        Corporate Governance.
 
(a)          Effective as of the Effective Time, in accordance with the FIBK Bylaws, the number of directors that will comprise the full Board of Directors of the Surviving Entity shall be sixteen (16).  Of the members of the initial Board of Directors of the Surviving Entity as of the Effective Time, (i) one (1) shall be the Chief Executive Officer of FIBK as of immediately prior to the Effective Time, (ii) an additional ten (10) shall be members of the Board of Directors of FIBK as of immediately prior to the Effective Time, designated by FIBK (the directors referred to in clauses (i) and (ii), the “FIBK Directors”), and (iii) an additional five (5) shall be members of the Board of Directors of GWB as of immediately prior to the Effective Time, designated by GWB (the directors referred to in this clause (iii), the “GWB Directors”); provided that any GWB Director must meet any applicable requirements or standards that may be imposed by a Regulatory Agency for service on the Board of Directors of FIBK.  Prior to the Effective Time, the parties (coordinating through the respective Chairman of each of GWB and FIBK) shall cooperate in good faith to mutually agree on the selection of the GWB Directors who will join the Board of Directors of the Surviving Entity, their respective classes, and their respective committee appointments, taking into account relevant considerations including skill sets, experience, diversity and inclusion, and the needs of the Board of Directors of the Surviving Entity; provided, that (i) the GWB Directors shall be apportioned among the three (3) classes of the Board of Directors of the Surviving Entity as nearly evenly as is possible, (ii) the Chairman of GWB as of immediately prior to the Effective Time shall be appointed to the Executive Committee of the Board of Directors of the Surviving Entity effective as of the Effective Time and (iii) the GWB Directors shall be eligible and given due consideration for committee service to the same extent as the FIBK Directors, and each GWB Director shall be appointed to at least two (2) standing committees of the Board of Directors of the Surviving Entity effective as of the Effective Time.

6.13        Acquisition Proposals.
 
(a)          Each party agrees that it will not, and will cause each of its Subsidiaries and its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, have or participate in any discussions with any person relating to any Acquisition Proposal or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.13) in connection with or relating to any Acquisition Proposal.  Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite FIBK Vote, in the case or FIBK, or the Requisite GWB Vote, in the case of GWB, a party receives an unsolicited bona fide written Acquisition Proposal that did not result from or arise in connection with a breach of this Section 6.13(a), such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party.  Each party will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than GWB or FIBK, as applicable, with respect to any Acquisition Proposal.  Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal.  Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof.  As used in this Agreement, “Acquisition Proposal” shall mean, with respect to FIBK or GWB, as applicable, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of a party and its Subsidiaries or twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party.
 
67

(b)          Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.
 
6.14        Public Announcements.  GWB and FIBK agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by the parties.  Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance or (ii) for such releases, announcements or statements that are consistent with other such releases, announcement or statements made after the date of this Agreement in compliance with this Section 6.14.
 
6.15        Change of Method.  GWB and FIBK shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of GWB and FIBK (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided that unless this Agreement is amended by agreement of each party in accordance with Section 9.1, no such change shall (i) alter or change the Exchange Ratio or the number of shares of FIBK Class A Common Stock received by holders of GWB Common Stock in exchange for each share of GWB Common Stock, (ii) adversely affect the Tax treatment of GWB’s stockholders or FIBK’s shareholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of GWB or FIBK pursuant to this Agreement or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner.  The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.1.
 
68

6.16        Takeover Statutes.  None of GWB, FIBK or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect.  If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.
 
6.17        Treatment of GWB Indebtedness.  (a) Upon the Effective Time, FIBK shall assume the due and punctual performance and observance of the covenants to be performed by GWB under the indentures set forth on Section 6.17(a) of the GWB Disclosure Schedule, and the due and punctual payment of the principal of (and premium, if any) and interest on, the notes governed thereby.  In connection therewith, (i) FIBK and GWB shall cooperate and use reasonable best efforts to execute and deliver any supplemental indentures and (ii) GWB shall use reasonable best efforts to execute and deliver any officer’s certificates or other documents, and to provide any opinions of counsel to the trustee thereof, in each case, required to make such assumption effective as of the Effective Time.
 
(b)          Upon the agreement of GWB and FIBK, GWB shall use reasonable best efforts to (i) redeem any or all of the trust preferred securities of GWB set forth on Section 6.17(b) of the GWB Disclosure Schedule (the “Trust Preferred Securities”) as specified by GWB and FIBK, collectively, at or prior to the Effective Time in accordance with, and pursuant to the terms of, the indentures applicable thereto set forth on Section 6.17(b) of the GWB Disclosure Schedule (the “Trust Preferred Indentures”), (ii) timely deliver all notices required to be delivered, and timely take all actions required to be taken, by the Trust Preferred Indentures in connection with the redemption of the Trust Preferred Securities, and (iii) concurrently with the consummation of the redemption of the Trust Preferred Securities, if no Trust Preferred Securities remain outstanding under any Trust Preferred Indentures, take all actions required to be taken by such Trust Preferred Indentures to cause such Trust Preferred Indentures to terminate and be of no further force and effect.
 
69

6.18         Exemption from Liability Under Section 16(b).  GWB and FIBK agree that, in order to most effectively compensate and retain GWB Insiders, both prior to and after the Effective Time, it is desirable that GWB Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of GWB Common Stock into shares of FIBK Class A Common Stock in the Merger and the conversion of GWB Equity Awards into corresponding FIBK Equity Awards in the Merger, and for that compensatory and retentive purposes agree to the provisions of this Section 6.18.  GWB shall deliver to FIBK in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of GWB subject to the reporting requirements of Section 16(a) of the Exchange Act (the “GWB Insiders”), and the Board of Directors of FIBK and of GWB, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of GWB) any dispositions of GWB Common Stock or GWB Equity Awards by the GWB Insiders, and (in the case of FIBK) any acquisitions of FIBK Class A Common Stock or FIBK Equity Awards by any GWB Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.
 
6.19         Tax Cooperation.  FIBK and GWB shall cooperate and use their respective reasonable best efforts in order for (i) FIBK to receive the opinion described in Section 7.2(c) and (ii) GWB to receive the opinion described in Section 7.3(c).
 
6.20         Conversion of FIBK Class B Common Stock.  Prior to the first annual meeting of shareholders of the Surviving Entity following the Effective Time, the Board of Directors of the Surviving Entity shall, in accordance with the articles of incorporation of the Surviving Entity and applicable law, adopt any resolutions and take any actions that are necessary or appropriate to determine that the number of shares of FIBK Class B Common Stock outstanding as of the record date for such annual meeting constitutes less than twenty percent (20%) of the aggregate number of shares of FIBK Common Stock then outstanding on such record date, such that each share of FIBK Class B Common Stock as of such record date shall be automatically converted as of such record date into one (1) fully paid and non-assessable share of FIBK Class A Common Stock pursuant to the articles of incorporation of the Surviving Entity (the “Conversion”).  From the date hereof until the date of the Conversion, FIBK and the Board of Directors of FIBK shall not take any action (including repurchasing FIBK Class A Common Stock or issuing additional shares of FIBK Class B Common Stock) that would prevent the Conversion in accordance with the preceding sentence.

(a)          Representations and Warranties.  The representations and warranties of FIBK set forth in Section 4.2(a) and Section 4.8(a) (in each case, after giving effect to the lead-in to Article IV) shall be true and correct (other than, in the case of Section 4.2(a), such failures to be true and correct as are de minimis) in each case as of the date of this Agreement and as of the Closing Date as though made on and as of the Closing Date (except to the extent such representations and warranties speak as of an earlier date, in which case as of such earlier date), and the representations and warranties of FIBK set forth in Section 4.1(a), Section 4.1(b) (but only with respect to FIBK Subsidiary Bank), Section 4.2(b) (but only with respect to FIBK Subsidiary Bank), Section 4.3(a) and Section 4.7 (read without giving effect to any qualification as to materiality or Material Adverse Effect set forth in such representations or warranties but, in each case, after giving effect to the lead-in to Article IV) shall be true and correct in all material respects as of the date of this Agreement and as of the Closing Date as though made on and as of the Closing Date (except to the extent such representations and warranties speak as of an earlier date, in which case as of such earlier date).  All other representations and warranties of FIBK set forth in this Agreement (read without giving effect to any qualification as to materiality or Material Adverse Effect set forth in such representations or warranties but, in each case, after giving effect to the lead-in to Article IV) shall be true and correct in all respects as of the date of this Agreement and as of the Closing Date as though made on and as of the Closing Date (except to the extent such representations and warranties speak as of an earlier date, in which case as of such earlier date); provided that for purposes of this sentence, such representations and warranties shall be deemed to be true and correct unless the failure or failures of such representations and warranties to be so true and correct, either individually or in the aggregate, and without giving effect to any qualification as to materiality or Material Adverse Effect set forth in such representations or warranties, has had or would reasonably be expected to have a Material Adverse Effect on FIBK.  GWB shall have received a certificate dated as of the Closing Date and signed on behalf of FIBK by the Chief Executive Officer or the Chief Financial Officer of FIBK to the foregoing effect.
 
72

(b)          Performance of Obligations of FIBK.  FIBK shall have performed in all material respects the obligations, covenants and agreements required to be performed by it under this Agreement at or prior to the Closing Date, and GWB shall have received a certificate dated as of the Closing Date and signed on behalf of FIBK by the Chief Executive Officer or the Chief Financial Officer of FIBK to such effect.

ARTICLE VIII          

TERMINATION AND AMENDMENT
 
8.1          Termination.  This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Requisite GWB Vote or the Requisite FIBK Vote:
 
(a)          by mutual written consent of FIBK and GWB;
 
(b)          by either FIBK or GWB if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise 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 or observe the obligations, covenants and agreements of such party set forth herein;
 
(c)          by either FIBK or GWB if the Merger shall not have been consummated on or before September 15, 2022 (the “Termination Date”), 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 obligations, covenants and agreements of such party set forth herein;
 
73

(d)          by either FIBK or GWB (provided, that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained herein) if there shall have been a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of GWB, in the case of a termination by FIBK, or FIBK, in the case of a termination by GWB, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by FIBK, or Section 7.3, in the case of a termination by GWB, and which is not cured within forty-five (45) days following written notice to GWB, in the case of a termination by FIBK, or FIBK, in the case of a termination by GWB, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the Termination Date);

74

(b)          (i)            In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of GWB or shall have been made directly to the stockholders of GWB or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the GWB Meeting) an  Acquisition Proposal, in each case with respect to GWB and (A) (x) thereafter this Agreement is terminated by either FIBK or GWB pursuant to Section 8.1(c) without the Requisite GWB Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.3 were satisfied or were capable of being satisfied prior to such termination), (y) thereafter this Agreement is terminated by FIBK pursuant to Section 8.1(d) as a result of a willful breach or (z) thereafter this Agreement is terminated by either GWB or FIBK pursuant to Section 8.1(g) as a result of the Requisite GWB Vote not having been obtained upon a vote taken thereon at the GWB Meeting (including any adjournment or postponement thereof), and (B) prior to the date that is twelve (12) months after the date of such termination, GWB enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then GWB shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay FIBK, by wire transfer of same-day funds, a fee equal to $70,000,000 (the “GWB Termination Fee”); provided, that for purposes of this Section 8.2(b)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”
 
(ii)            In the event that this Agreement is terminated by (x) FIBK pursuant to Section 8.1(f) or (y) either FIBK or GWB pursuant to Section 8.1(g) as a result of the Requisite GWB Vote not having been obtained upon a vote taken thereon at the GWB Meeting (including any adjournment or postponement thereof) and at such time FIBK could have terminated this Agreement pursuant to Section 8.1(f), then GWB shall pay FIBK, by wire transfer of same-day funds, the GWB Termination Fee within two (2) business days of the date of termination.

(c)          (i)            In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of FIBK or shall have been made directly to the shareholders of FIBK or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the FIBK Meeting) an Acquisition Proposal, in each case with respect to FIBK and (A) (x) thereafter this Agreement is terminated by either FIBK or GWB pursuant to Section 8.1(c) without the Requisite FIBK Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.2 were satisfied or were capable of being satisfied prior to such termination), (y) thereafter this Agreement is terminated by GWB pursuant to Section 8.1(d) as a result of a willful breach or (z) thereafter this Agreement is terminated by either GWB or FIBK pursuant to Section 8.1(g) as a result of the Requisite FIBK Vote not having been obtained upon a vote taken thereon at the FIBK Meeting (including any adjournment or postponement thereof), and (B) prior to the date that is twelve (12) months after the date of such termination, FIBK enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then FIBK shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay GWB a fee equal to $105,000,000 (the “FIBK Termination Fee”) by wire transfer of same-day funds; provided, that for purposes of this Section 8.2(c)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”
 
75

(ii)           In the event that this Agreement is terminated by (x) GWB pursuant to Section 8.1(e), or (y) either FIBK or GWB pursuant to Section 8.1(g) as a result of the Requisite FIBK Vote not having been obtained upon a vote taken thereon at the FIBK Meeting (including any adjournment or postponement thereof) and at such time GWB could have terminated this Agreement pursuant to Section 8.1(e), then FIBK shall pay GWB, by wire transfer of same-day funds, the FIBK Termination Fee within two (2) business days of the date of termination.

(d)          Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages to the extent permitted herein, in no event shall either party be required to pay the GWB Termination Fee or the FIBK Termination Fee, as applicable, more than once.
 
(e)          Each of FIBK and GWB acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if FIBK or GWB, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the GWB Termination Fee or the FIBK Termination Fee, as applicable, or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit.  In addition, if FIBK or GWB, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts at a rate per annum equal to the “prime rate” published in the Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

9.6          Interpretation.  The parties have participated jointly in negotiating and drafting this Agreement.  In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.  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.”  The word “or” shall not be exclusive.  References to “the date hereof” shall mean the date of this Agreement.  As used in this Agreement, the “knowledge” of GWB means the actual knowledge of any of the officers of GWB listed on Section 9.6 of the GWB Disclosure Schedule, and the “knowledge” of FIBK means the actual knowledge of any of the officers of FIBK listed on Section 9.6 of the FIBK Disclosure Schedule.  As used herein, (i) the term “person” means any individual, corporation (including not‑for‑profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or other entity of any kind or nature, (ii) an “affiliate” of a specified person is any person that directly or indirectly controls, is controlled by, or is under common control with, such specified person, (iii) the term “made available” means any document or other information that was (a) provided by one party or its Representatives to the other party and its Representatives at least one (1) day prior to the date hereof, (b) included in the virtual data room of a party at least one (1) day prior to the date hereof or (c) filed by a party with the SEC and publicly available on EDGAR at least one (1) day prior to the date hereof and (iv) the term “business day” means any day other than a Saturday, a Sunday or a day on which banks in Billings, Montana or Sioux Falls, South Dakota are authorized by law or executive order to be closed.  The GWB Disclosure Schedule and the FIBK Disclosure Schedule, as well as all other schedules and all exhibits hereto, shall be deemed part of this Agreement and included in any reference to this Agreement.  Nothing contained herein shall require any party or person to take any action in violation of applicable law.
 
78

9.7          Counterparts.  This Agreement may be executed in counterparts, 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 parties, it being understood that all parties need not sign the same counterpart.
 
9.8          Entire Agreement.  This Agreement (including the documents and instruments referred to herein) together with the Confidentiality Agreement constitutes the entire agreement among the parties and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.
 
9.9          Governing Law; Jurisdiction.
 
(a)          This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to any applicable conflicts of law principles (except that matters relating to the fiduciary duties of the Board of Directors of FIBK shall be subject to the laws of the State of Montana).
 
(b)          Each party agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any federal or state court of competent jurisdiction located in the State of Delaware (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 9.5.
 
9.10        Waiver of Jury Trial.  EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE EXTENT PERMITTED BY LAW AT THE TIME OF INSTITUTION OF THE APPLICABLE LITIGATION, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.  EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT:  (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.
 
79

9.11        Assignment; Third-Party Beneficiaries.  Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other party.  Any purported assignment in contravention hereof shall be null and void.  Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.  Except as otherwise specifically provided in Section 6.7, this Agreement (including the documents and instruments referred to herein) is not intended to confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein.  The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties.  Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person.  In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto.  Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.
 
9.12        Specific Performance.  The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and, accordingly, that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger), in addition to any other remedy to which they are entitled at law or in equity.  Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.
 
9.13        Severability.  Whenever possible, each provision or portion of any provision of this Agreement shall 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 shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

80

9.14        Confidential Supervisory Information.  Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(b)(1) and as identified in 12 C.F.R. § 309.5(g)(8)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable law.  To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentence apply.
 
9.15         Delivery by Facsimile or Electronic Transmission.  This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e‑mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.  No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or e‑mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e‑mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.

The number of authorized shares of any class or classes of stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of at least a majority of the voting power of the issued and outstanding shares of Common Stock, voting together as a single class.


2.          Board of Directors.  Article VI of the Amended and Restated Articles of Incorporation of the Corporation is hereby amended to add the following new Section 6:

Section 6.  Except as otherwise provided for or fixed by or pursuant to the provisions of Article IV hereof in relation to the rights of the holders of Preferred Stock to elect directors under specified circumstances, the Board of Directors shall be and is divided into three classes, as nearly equal in number of directors as possible, designated: Class I, Class II and Class III.  The Board of Directors is authorized to assign to such classes directors already in office at the time the First Amendment to the Third Amended and Restated Articles of Incorporation becomes effective (the “Effective Date”), provided that notwithstanding anything to the contrary any directors already in office at the Effective Date and who were elected, or whose appointment was ratified, at any annual or special meeting of shareholders for a term of office to expire at (i) the first annual meeting of shareholders following the Effective Date, shall be assigned to Class I, (ii) the second annual meeting of shareholders following the Effective Date, shall be assigned to Class II, and (iii) the third annual meeting of shareholders following the Effective Date, shall be assigned to Class III.  Except as otherwise provided in this Section 6, the term of office of the directors initially assigned to Class I at the Effective Date will expire at the first annual meeting of shareholders following the Effective Date; the term of office of the directors initially assigned to Class II at the Effective Date will expire at the second annual meeting of shareholders following the Effective Date; the term of office of the directors initially assigned to Class III at the Effective Date will expire at the third annual meeting of shareholders following the Effective Date; and the term of office of any directors appointed by the Board of Directors to fill newly created directorships resulting from any increase in the number of directors or any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other cause shall expire at the next annual meeting of shareholders after their appointment in accordance with these Third Amended and Restated Articles of Incorporation, as amended, and the Bylaws of the Corporation. At each annual meeting of shareholders beginning with the first annual meeting of shareholders following the Effective Date, the successors of the directors whose terms expire at that meeting shall be elected for a term of three years. The directors of each class will hold office until the expiration of the term of such class and until their respective successors shall have been elected and qualified, or until such director’s earlier death, resignation or removal. Notwithstanding anything to the contrary, the Board of Directors is authorized to take appropriate steps, by designation of short terms or otherwise, to return the rotation of election of directors to staggered terms as contemplated by, and established and fixed in accordance with, this Section 6 and the Bylaws of the Corporation; provided that in all cases the Board of Directors shall comply with Section 6.12(b) of that certain Agreement and Plan of Merger, by and between Great Western Bancorp, Inc. and the Corporation, dated as of September 15, 2021 (as the same may be amended, supplemented or modified from time to time).
