Immediately following the Merger, pursuant to the Bank Merger Agreement and as set forth in Section 1.7, the Bank will be merged with and into Glacier Bank, with Glacier Bank as the surviving bank.

1.2 Merger Consideration. Subject to the provisions of this Agreement, including Section 1.3 as of the Effective Date:

1.2.1 Outstanding GBCI Common Stock. The shares of GBCI Common Stock issued and outstanding immediately prior to the Effective Time will remain as issued and outstanding.

1.2.2 Outstanding GNTY Stock. Each share of GNTY Stock issued and outstanding as of the Effective Time will be converted into and represent the right to receive from GBCI, in accordance with Section 1.6, (a) the Per Share Stock Consideration, plus (b) any cash in lieu of fractional shares of GBCI Common Stock in accordance with Section 1.3.

1.3 No Fractional Shares. No fractional shares of GBCI Common Stock will be issued in the Merger. In lieu of fractional shares, if any, each holder of GNTY Stock who is otherwise entitled to receive a fractional share of GBCI Common Stock after adding together all shares of GBCI Common Stock received by such holder in the Merger will receive an amount of cash equal to the product of such fractional share multiplied by the GBCI Average Closing Price. Such fractional share interests will not include the right to vote or receive dividends or any interest on dividends.

1.4 GNTY Stock Awards.

1.4.1 Options.

(a) Outstanding GNTY Options. The GNTY Options have been duly granted and remain outstanding pursuant to the GNTY Stock Plan. If any holder of a GNTY Option that may by its terms be exercised provides a notice of exercise of such GNTY Option to GNTY on or before the 30th calendar day prior to the Effective Date (such date, the “Option Exercise Notice Deadline”), GNTY shall issue shares of GNTY Stock upon such exercise in accordance with the terms of the GNTY Options and the applicable GNTY Stock Plan, including receipt of payment of the exercise price therefor, and each such share of GNTY Stock shall be converted into the right to receive the Per Share Stock Consideration and cash in lieu of fractional shares in accordance with Section 1.3 at the Effective Time. No exercise of GNTY Options shall be permitted if an option holder fails to provide notice of exercise to GNTY by the Option Exercise Notice Deadline. With respect to GNTY Options that remain outstanding and unexercised at the Effective Time, such GNTY Options, whether vested or unvested at the Effective Time, and without any action on the part of any holder thereof, will be assumed by GBCI and will be automatically converted into an option (a “Converted Option”) to purchase GBCI Common Stock on the same terms and conditions as are in effect with respect to the GNTY Option immediately prior to the Effective Time, except that (a) to the extent provided for in the applicable option award agreement under the GNTY Stock Plan, each such Converted Option will be fully vested and exercisable immediately following the Effective Time. (b) each such Converted Option may be exercised solely for shares of GBCI Common Stock, (c) the number of shares of GBCI Common Stock subject to such Converted Option will be equal to the number of shares of GNTY Stock subject to the GNTY Option immediately prior to the Effective Time, multiplied by the Per Share Stock Consideration and rounded down to the nearest whole share of GBCI Common Stock, and (d) the per-share exercise price for each such Converted Option will be adjusted by dividing the per-share exercise price of the GNTY Option immediately prior to the Effective Time by the Per Share Stock Consideration (rounded up to the nearest whole cent); provided, however, that in no case shall the conversion of a GNTY Option

- 15 -

be performed in a manner that is not in compliance with the adjustment requirements of IRC Section 409A and, to the extent that the GNTY Option is an incentive stock option under IRC Section 422, the adjustment requirements of IRC Section 424(a). GNTY shall, if requested by GBCI, obtain from each holder of GNTY Options entitled to become a Converted Option under this Section a fully executed option assumption agreement in form and substance reasonably satisfactory to GBCI. The execution of such assumption agreement shall be a condition to the receipt of a Converted Option. Consistent with the terms of the GNTY Stock Plan and the documents governing the outstanding GNTY Options under such plan, the Merger shall not terminate any of the GNTY Options assumed by GBCI.

(b) Special Dividend Adjustment. The board of directors of GNTY (or a committee thereof to the extent applicable) may take any necessary actions to ensure that the terms of the GNTY Options then outstanding are equitably adjusted to take into account the payment of the special dividend, if applicable, pursuant to Section 4.14 of this Agreement; provided, however, that (i) in no case shall such adjustment to a GNTY Option be performed in a manner that is not in compliance with the adjustment requirements of IRC Section 409A and, to the extent that the GNTY Option is an incentive stock option under IRC Section 422, the adjustment requirements of IRC Section 424(a), and (ii) such adjustment shall be performed in accordance with Schedule 1.4.1(b).

(c) Registration. GBCI shall file with the SEC a registration statement on Form S-8 (or any successor form), or another appropriate form with respect to shares of GBCI Common Stock issuable upon exercise of the Converted Options, and shall use its reasonable best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as the Converted Options remain outstanding. As soon as practicable after the registration of such shares, GBCI shall deliver to the holders of Converted Options an appropriate notice setting forth such holders’ rights pursuant to GBCI’s 2025 Stock Incentive Plan and agreements evidencing such Converted Options, and stating that such Converted Options have been assumed by GBCI and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 1.4 after giving effect to the Merger and the terms of the GNTY Stock Plan).

1.4.2 Restricted Stock. Immediately prior to the Effective Time, each outstanding restricted stock award of GNTY (the “GNTY Restricted Stock”) shall, automatically and without any action on the part of the holder thereof, vest and be settled through the issuance of unrestricted shares of GNTY Stock in accordance with the terms of each award agreement and the applicable GNTY Stock Plan, and each such share of GNTY Stock shall be converted into the right to receive at the Effective Time the Per Share Stock Consideration and cash in lieu of fractional shares in accordance with Section 1.3.

1.4.3 Corporate Action. Prior to the Effective Time, the board of directors of GNTY (or a committee thereof to the extent applicable) will take all reasonable corporate actions and adopt such resolutions as may be necessary or appropriate to effectuate this Section 1.4.

- 16 -

1.5 Deposit of Cash and Shares. At or prior to the Closing, GBCI will deposit, or will cause to be deposited, with the Exchange Agent, for the benefit of the holders of GNTY Stock, for exchange in accordance with this Section 1.5 and Section 1.6, (a) evidence of shares in book-entry form, representing the GBCI Shares for payment of the Total Merger Consideration in full; and (b) the aggregate cash in lieu of fractional shares to be paid in accordance with Section 1.3. Such cash and evidence of the GBCI Shares, together with any dividends or distributions with respect thereto, are referred to in this Agreement as the “Exchange Fund.” To the extent that the Exchange Fund diminishes for any reason below the amount required to promptly pay in full the amounts contemplated by this Section 1.5, GBCI shall promptly replace or restore such amounts so as to ensure that the Exchange Fund is at all times maintained at a level sufficient to make in full such payments contemplated by this Article 1. The Exchange Fund shall not be used for any purpose other than as provided in this Agreement.

1.6 Certificates and Uncertificated Shares.

1.6.1 Letter of Transmittal; Uncertificated Shareholder Letter.

(a) GBCI will use its reasonable best efforts to cause the Exchange Agent, within five Business Days following the Effective Date, to mail to each holder of record of a certificate evidencing shares of GNTY Stock (a “Certificate”) a customary form letter of transmittal advising such holder of the procedure for the conversion of each holder’s GNTY Stock evidenced by a Certificate into the consideration to which such holder may be entitled pursuant to this Agreement (the “Letter of Transmittal”).

(b) GBCI will use its reasonable best efforts to cause the Exchange Agent, within five Business Days following the Effective Date, to mail to each holder of record of evidence of a book-entry account statement relating to the ownership of shares of GNTY Stock (“Uncertificated Shares”) a customary form letter advising such holder that all of such holder’s Uncertificated Shares of GNTY Stock have automatically converted into the right to receive the consideration to which such holder may be entitled pursuant to this Agreement (the “Uncertificated Shareholder Letter”).

1.6.2 Payment Procedures.

(a) Each Certificate will, from and after the Effective Time, be deemed for all corporate purposes to represent and evidence only the right to receive the Per Share Stock Consideration (and cash for fractional shares in accordance with Section 1.3) owing in respect of the number of shares of GNTY Stock represented thereby. Following the Effective Time, holders of shares of GNTY Stock represented by a Certificate will provide to the Exchange Agent a properly completed and executed Letter of Transmittal or transfer their shares of GNTY Stock by an “agent’s message” to the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in exchange for, (i) evidence of issuance in book-entry form equal to the Per Share Stock Consideration multiplied by the aggregate number of shares of GNTY Stock represented by such Certificates, rounded down to the nearest whole number; and (ii) cash in lieu of fractional shares, if any, to which such holder is entitled in accordance with Section 1.3. Until such “agent’s message” (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) and a properly executed Letter of Transmittal is received by the Exchange Agent (or, in the case of a lost, stolen, or destroyed Certificate, the procedure in Section 1.6.3 is complied with), the holder of shares of GNTY Stock represented by a Certificate will not be entitled to receive his, her or its Per Share Stock Consideration or other amounts payable pursuant hereto.

- 17 -

(b) Each Uncertificated Share will, from and after the Effective Time, be deemed for all corporate purposes to represent and evidence only the right to receive the Per Share Stock Consideration (and cash for fractional shares in accordance with Section 1.3) owing in respect of the number of shares of GNTY Stock represented thereby. Following the Effective Time, holders of Uncertificated Shares will automatically receive, as described in the Uncertificated Shareholder Letter, (i) evidence of issuance in book-entry form equal to the Per Share Stock Consideration multiplied by the aggregate number of shares of GNTY Stock represented by such Uncertificated Shares, rounded down to the nearest whole number; and (ii) cash in lieu of fractional shares, if any, to which such holder is entitled in accordance with Section 1.3.

1.6.3 Lost, Stolen, and Destroyed Certificates.

(a) GNTY will use commercially reasonable efforts to contact GNTY shareholders of record prior to the Effective Date and determine whether any Certificates have been lost, stolen or destroyed. Prior to the Effective Date, GNTY will be authorized to re-issue Certificates or issue evidence of ownership in book-entry form if the holder provides GNTY with (i) satisfactory evidence in a reasonable form that the holder owns GNTY Stock and that the Certificate representing this ownership is lost, stolen, or destroyed, (ii) any affidavit or security GNTY’s transfer agent may require in accordance with its policies or procedures, and (iii) any reasonable additional assurances that GNTY may require.

(b) Beginning after the Effective Date, with respect to any remaining Certificates that have been lost, stolen, or destroyed, the Exchange Agent will be authorized to issue or pay the holder’s Per Share Stock Consideration and cash in lieu of fractional shares in accordance with Section 1.3 in exchange thereof, if the holder provides GBCI with: (i) satisfactory evidence in a reasonable form that the holder owns GNTY Stock and that the Certificate representing this ownership is lost, stolen, or destroyed, (ii) any affidavit or security GBCI’s transfer agent may require in accordance with its policies and procedures (including such bond as may be required by the Exchange Agent in accordance with such policies), and (iii) any reasonable additional assurances that GBCI or the Exchange Agent may require.

1.6.4 Rights to Dividends and Distributions. After the Effective Time, no holder of any Certificate will be entitled to receive any dividends or other distributions otherwise payable to holders of record of GBCI Common Stock on any date on or after the Effective Date, unless the holder has surrendered in accordance with this Agreement his, her or its Certificates (or has met the requirements of Section 1.6.3) in exchange for evidence of GBCI stock ownership. Surrender of Certificates will not deprive the holder of any dividends or distributions that the holder is entitled to receive as a record holder of GNTY Stock prior to the Effective Time. When the holder surrenders his, her or its Certificates in exchange for GBCI Shares, the holder shall become a shareholder of record of GBCI and shall receive the amount, without interest, of any cash dividends and any other distributions declared and distributed after the Effective Time on the whole number of GBCI Shares into which the holder’s GNTY Stock was converted at the Effective Time.

- 18 -

1.6.5 Unclaimed Merger Consideration. Any portion of the Exchange Fund that remains unclaimed by shareholders of GNTY on a date that is 12 months after the Effective Date may be returned to GBCI, at GBCI’s election. To the extent so returned, holders of GNTY Stock who have not, prior to such time, complied with the provisions of this Section 1.6 will, from such time forward, look only to GBCI for payment of the Per Share Stock Consideration and cash in lieu of fractional shares to which they are entitled and/or unpaid dividends and distributions on the GBCI Shares deliverable with respect to each share of GNTY Stock held by such holders as determined pursuant to this Agreement, in each case, without any interest. Neither GBCI nor GNTY will be liable to any holder of GNTY Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. In the event of a dispute with respect to ownership of GNTY Stock, GBCI and the Exchange Agent shall be entitled to deposit the Per Share Stock Consideration and cash in lieu of fractional shares represented thereby in escrow with an independent third party with instructions to release the Per Share Stock Consideration as determined between the disputing parties promptly upon resolution of the dispute, and thereafter be relieved of any responsibility with respect to any claims thereto.

1.7 Bank Merger. The board of directors of Glacier Bank and the Bank, respectively, have adopted the Bank Merger Agreement and have caused the Bank Merger Agreement to be executed by Glacier Bank and the Bank simultaneously with the execution and delivery of this Agreement. Prior to the Effective Time, GBCI and GNTY, as the sole shareholders of Glacier Bank and the Bank, respectively, shall approve the Bank Merger and the Bank Merger Agreement. Immediately following the Effective Time, Glacier Bank and the Bank shall (a) consummate the Bank Merger and (b) file with the Secretary of State of Montana articles of merger or other such documents, in the form required by and executed in accordance with the relevant provisions of the MBCA.

As of their respective dates of filing with the SEC (or, if amended or superseded by a subsequent filing prior to the date hereof, as of the date of such subsequent filing), the GNTY SEC Reports complied (and each GNTY SEC Report filed subsequent to the date hereof and prior to the Effective Time will comply) in all material respects with applicable Laws and did not or will not, as the case may be, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. There are no outstanding comments from, or unresolved issues raised by, the SEC with respect to any of the GNTY SEC Reports. To the Knowledge of GNTY, no enforcement action by the SEC relating to its disclosures in any GNTY SEC Report is pending or threatened against GNTY or its directors or officers.

(a) GNTY has no ERISA Affiliates (other than the Bank and the Bank’s Subsidiaries).

(b) For purposes of this Agreement, “Plan,” or “Plans,” individually or collectively, means any “employee benefit plan,” as defined in Section 3(3) of ERISA, maintained by GNTY, the Bank or any other GNTY Subsidiary, as the case may be. GNTY and the GNTY Subsidiaries are not now nor, within the past six years, have been a contributing employer to, or sponsor of, a “multiemployer plan” within the meaning of ERISA Section 3(37) or 4001(a)(3) or a single employer plan subject to Title IV of ERISA.

(c) Schedule 3.1.18(c) sets forth a list, as of the Execution Date, of (i) all Plans, stock purchase plans, restricted stock and stock option plans, and other deferred compensation arrangements, and (ii) all other material employee benefit plans, programs, policies, agreements, collective bargaining agreements, or other arrangements providing for compensation, severance, incentive compensation, bonuses, performance awards, or other compensation, or for fringe, retirement, death, disability or medical benefits or other employee benefits or remuneration of any kind, whether written or unwritten, funded or unfunded, and whether or not subject to ERISA, that is or has been sponsored, maintained, contributed to, or required to be contributed to, by GNTY or any GNTY Subsidiary for the benefit of any employees or former employees of GNTY or any GNTY Subsidiary (collectively, “Employees”), including, without limitation, all salary continuation or supplementation agreements between GNTY or any GNTY Subsidiary and any of their respective officers, directors, or employees

(collectively, the “Compensation Plans”).

(d) All of the Compensation Plans have been maintained, and are in compliance (both in form and operation) in all material respects with, any applicable Laws, including ERISA and the IRC. Each Plan that is an “employee pension benefit plan” within the meaning of ERISA Section 3(2) and that is intended to be qualified under IRC Section 401(a), has either received a favorable determination letter from the Internal Revenue Service or consists of a master, prototype, or volume submitter plan which has received an opinion or advisory letter from the Internal Revenue Service and, as of the date hereof no such determination letter has been revoked, no revocation has been threatened, and, to the Knowledge of GNTY, nothing has occurred since the date of such letter that would reasonably be expected to adversely affect the qualified status of each such Plan. All such Plans have been timely amended for all such requirements. No litigation, audit, or investigation relating to the Compensation Plans is pending or, to the Knowledge of GNTY, threatened. To the Knowledge of GNTY, there has been no “non-exempt prohibited transaction”, as such term is defined in ERISA Section 406 or IRC Section 4975, with respect to any Plan and neither GNTY nor any GNTY Subsidiary has engaged in such non-exempt prohibited transactions with respect to any Plan.

(e) All contributions required to be made under the terms of any Plans have been timely made and paid in full or, to the extent not required to be made or paid on or before the date of this Agreement, have been accrued and reflected in the GNTY Financial Statements.

None of GNTY or any GNTY Subsidiary have provided, or are required to provide, security to any Plan under IRC Sections 401(a)(29) or 412(f) of ERISA Sections 306 and 307.

(f) Except as required by IRC Section 4980B or Part 6 of Subtitle B of Title I of ERISA (or any similar state Law), neither GNTY nor any GNTY Subsidiary have any material obligations for retiree health or life benefits.

(g) No provision of the documents governing any Plan contains restrictions on the rights of GNTY or any GNTY Subsidiary or their successors to amend, merge, or terminate any Plan without incurring liability under such Plan other than normal liabilities for benefits and administrative costs incident to such amendment, merger or termination. Neither GNTY nor any GNTY Subsidiary has a commitment or obligation, or has made any representations, to any employee, officer, director, independent contractor or consultant, whether or not legally binding, to adopt, amend, modify or terminate any Plan or any collective bargaining agreement, in connection with the consummation of the Transactions or otherwise.

- 37 -

(h) Except as disclosed in Schedule 3.1.18(h), the Transactions (either alone or upon the occurrence of any additional or subsequent events) will not result in (i) vesting, acceleration, or increase of any amounts payable under any Compensation Plan, (ii) any increase in benefits under any Compensation Plan, (iii) payment of any severance, true-up, change in control, or similar payments or compensation or any forgiveness of any indebtedness under any Compensation Plan, or (iv) result in an “excess parachute payment” within the meaning of IRC Section 280G(b).

The requirements of COBRA and any applicable state continuation laws have been met with respect to each applicable Plan in all material respects.

(k) Each Compensation Plan that is subject to IRC Section 409A has been operated in all material respects in compliance with, and is in documentary compliance with such section and all applicable regulations and regulatory guidance (including, without limitation, proposed regulations, notices, and rulings).

3.1.19 Required Vote; Takeover Laws.

(a) The affirmative vote of the holders of two thirds of the outstanding shares of GNTY Stock entitled to vote is necessary to approve this Agreement and the Merger on behalf of GNTY.

(b) GNTY and the Bank have taken all action required to be taken in order to exempt this Agreement and the Transactions from, and this Agreement and the Transactions are exempt from, the requirements of any “moratorium,” “control share,” “fair price,” “business combination,” or other antitakeover Laws and regulations of any state, including, without limitation, the State of Texas, applicable to it (collectively, “Takeover Laws”). GNTY and the Bank have taken all action required to be taken by them in order to make this Agreement and the Transactions comply with, and this Agreement and the Transactions do comply with, the requirements of any articles, sections, or provisions of the certificate of formation or articles of association, as applicable, and bylaws of GNTY and the Bank concerning “business combination,” “fair price,” “voting requirement,” “constituency requirement,” or other related provisions (collectively, the “Takeover Provisions”).

To the extent not included in the Final Transaction Related Expenses, GNTY and the Bank shall, prior to the date of calculation of GNTY Closing Capital, pay, provide for the payment of, or reflect as a liability any change-in-control, termination or similar payments required to be made under, or upon termination of, the Compensation Plans or closing of the Transactions. All resolutions, notices, or other documents issued, adopted or executed by GNTY or the Bank in connection with the implementation of this Section 4.1.3(b) shall be subject to GBCI’s reasonable prior review and approval, which approval shall not be unreasonably withheld, conditioned or delayed, and GNTY and the Bank shall cooperate reasonably with GBCI in connection with the actions required by this subsection and subsection (c) below, and in the implementation of Section 6.4 below.

4.1.6 Updates of Financial Statements. GNTY will deliver to GBCI the Subsequent GNTY Financial Statements and Subsequent Bank Financial Statements for each month ending after the Execution Date and before Closing or an earlier Termination Date, within 15 days after each such month-end (including year-end). The Subsequent GNTY Financial Statements and the Subsequent Bank Financial Statements: (w) will be prepared from the books and records of GNTY and the Bank; (x) will present fairly in all material respects the financial position and operating results of GNTY and/or the Bank at the times indicated and for the periods covered; (y) will be prepared in accordance with GAAP (except for the absence of notes and exceptions from GAAP identified in Section 3.1.4) or the regulations promulgated by applicable regulatory authorities, to the extent then applicable to such financial statement, and (z) will reflect all liabilities, of GNTY and/or the Bank on the respective dates and for the respective periods covered, except for liabilities: (i) not required to be so reflected on the face of a balance sheet in accordance with GAAP or regulatory requirements, or (ii) not material in amount. All contingent liabilities known to GNTY that are required to be reflected in footnotes in accordance with GAAP but not recorded on the Subsequent GNTY Financial Statements will be disclosed in writing to GBCI.

4.1.7 Acquisition Proposal. GNTY and the Bank will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any Acquisition Proposal. GNTY agrees that neither it nor any of its Subsidiaries will, and GNTY will direct and use its commercially reasonable efforts to cause its and its Subsidiaries’ directors, officers, employees, agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by it or any of its Subsidiaries) not to initiate, solicit, encourage or take any other action to facilitate any inquiries or the making of any proposal or offer (including, without limitation, any proposal or offer to shareholders of GNTY) with respect to an Acquisition Event (any such proposal or offer, an “Acquisition Proposal”) or engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any Person relating to an Acquisition Proposal, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal; except that, in the event GNTY receives an unsolicited bona fide Acquisition Proposal and the board of directors of GNTY determines prior to approval of this Agreement and the Merger by GNTY’s shareholders at the GNTY Meeting, in good faith and after consultation with independent legal counsel, that (a) such Acquisition Proposal constitutes or is reasonably expected to result in a Superior Proposal, and (b) fiduciary duties applicable to it require it to engage in negotiations with, provide confidential information or data to, or have any discussions with a Person in connection with such Acquisition Proposal, GNTY may do so to the extent the board of directors of GNTY determines it is required by its fiduciary duties. In such event, prior to providing any confidential information or data to any such Person, GNTY and such Person shall have executed a confidentiality agreement on terms at least as favorable to GNTY as those contained in the Confidentiality Agreement. GNTY will further notify GBCI in writing promptly (and in any event within two Business Days) if any such inquiries or proposals are received by, any such information is requested from, or any such negotiations or discussions are sought to be initiated or continued with GNTY, or if any such inquiry, proposal or request is thereafter materially modified or amended, including providing to GBCI the material terms and conditions of any such proposal or inquiry in connection with each required notice, together with a copy of any written proposals received. GNTY will take the necessary steps to inform the appropriate individuals or entities referred to in the second sentence of this Section 4.1.7 of the obligations to be undertaken in this Section 4.1.7 and shall be responsible for any breach or violation of this Section 4.1.7 by such Persons.

- 49 -

4.1.8 Status of Title.

(a) Reports. GNTY will use its commercially reasonable efforts to provide GBCI, no later than 45 days after the Execution Date, lot book, preliminary title reports, title commitments, or other similar reports for all Owned Real Estate and Leased Property subject to a ground lease under which GNTY is a ground tenant to be issued by title insurance companies reasonably satisfactory to GBCI (the “Title Companies”), the cost of which shall be paid by GNTY and treated as a Transaction Expense for purposes of this Agreement. Such reports shall show the current status of title to the Owned Real Estate and Leased Property subject to a ground lease under which GNTY is a ground tenant. Within 30 days after the date on which GNTY delivers the foregoing reports to GBCI for its review, GBCI will inform GNTY in writing whether, and in what manner, it objects to any of the exceptions to title shown in any of the title reports (such notice, an “Objection Notice”). GNTY will, within 20 days of the date on which it receives a written Objection Notice from GBCI, inform GBCI if there are any objections that it is unable or unwilling to remove or cure at or prior to Closing (the “Response Notice”). GNTY will not, in any event, be obligated to seek removal, cure of, or otherwise remedy exceptions that are (a) nonmonetary exceptions that do not prohibit or materially interfere with the use of the Owned Real Estate and Leased Property subject to a ground lease under which GNTY is a ground tenant as bank branch locations or as otherwise used by GNTY or the Bank as of the Execution Date, (b) monetary or non-monetary exceptions disclosed in the GNTY Financial Statements, or (c) matters that GBCI has not taken objection to in an Objection Notice (such title exceptions together, “Permitted Exceptions”). GNTY will in good faith use commercially reasonable efforts, at GNTY’s expense, to remove, cure, or otherwise remedy any matters set forth in the Response Notice that are not Permitted Exceptions that are susceptible to cure.

(b) Title Policies. At Closing, if requested by GBCI, GNTY will reasonably cooperate with GBCI’s efforts to cause the Title Companies to provide GBCI with standard coverage title insurance policies (or at GBCI’s option, extended coverage title policies, including but not limited by completing commercially reasonable owner’s affidavits, provided the additional premium for extended title coverage shall be at GBCI’s expense) issued with respect to each of the Properties constituting Owned Real Estate or Leased Property subject to a ground lease under which GNTY is a ground tenant, in an amount commensurate with the greater of (i) the book value or (ii) the tax assessed value, of each such Real Property, dated as of the Effective Date, insuring fee title in GBCI or such Subsidiary of GBCI, as so designated by GBCI, and that each such Real Property is unencumbered by any Liens, other than the Permitted Exceptions, or at GBCI’s option, to obtain an additional insured endorsement (e.g., CLTA 107.9 or T-26), or a substitute insured endorsement (e.g., OTIRO 90), or a similar endorsement insuring that Glacier Bank is the “Insured” under, and as defined in, any existing title policy held by GNTY or Bank with respect to each of the Properties constituting Owned Real Estate, and if available a policy date down endorsement with respect to such title policy. Standard coverage

- 50 -

title insurance policies for each of the Real Properties listed on Schedule 4.1.8(b) will be obtained at GNTY’s expense. Any other standard coverage title insurance policies desired by GBCI, together with the additional premiums for extended title coverage or title endorsements desired by GBCI for any title insurance policy to be obtained under this Section 4.1.8(b) shall be obtained at GBCI’s expense.

4.1.9 Directors’ and Officers’ Liability. Before the Effective Date, GNTY will notify its directors’ and officers’ liability insurers of the Merger and of all pending or, to the Knowledge of GNTY, threatened claims, actions, suits, proceedings or investigations asserted or claimed against any Person entitled to indemnification pursuant to Section 6.3 and known to GNTY, or circumstances reasonably deemed by GBCI to be likely to give rise thereto, in accordance with terms and conditions of the applicable policies.

4.1.10 Review of Loans. GNTY and the Bank will permit GBCI and its advisors, at GBCI’s sole cost and expense, reasonable access to the Bank’s records necessary to conduct an examination of the Bank’s loans to determine credit quality and the adequacy of the Bank’s ACL and to establish, following the Effective Time, appropriate accounting adjustments under Financial Accounting Standards No. 141R published by the Financial Accounting Standards Board.

4.2 Registration Statement; GNTY Shareholders Meeting.

4.2.1 Preparation of Registration Statement.

(a) GBCI and GNTY will use their commercially reasonable efforts to jointly prepare and jointly file a Registration Statement on Form S-4 (together with any amendments or supplements, the “Registration Statement”) and related proxy statement/prospectus (the “Proxy Statement/Prospectus”) with the SEC within 60 days after the Execution Date for registration of the GBCI Shares to be issued in the Merger and solicitation of proxies for the GNTY Meeting.

(b) The parties will cooperate with each other in preparing the Registration Statement and Proxy Statement/Prospectus, and will use their commercially reasonable efforts to promptly obtain the clearance of the SEC and, if required, any appropriate state securities regulators and any other required regulatory approvals, to issue the Proxy Statement/Prospectus.

(c) GNTY and GBCI will each provide to the other, for inclusion in the Registration Statement, all required information relating to such Person or its Affiliates as the Person making such filing may reasonably request for the purpose of including such data and information in the Registration Statement and any amendments or supplements thereto. GNTY and its counsel shall be given the opportunity to review and comment on the Registration Statement, including any amendments thereto and related correspondence with the SEC, before it is filed with the SEC. Nothing will be included in the Registration Statement, or the Proxy Statement/Prospectus, or any additional proxy solicitation materials with respect to any party to this Agreement unless approved by that party, which approval will not be unreasonably withheld, conditioned, or delayed. When the Registration Statement becomes effective, and at all times

- 51 -

subsequent to such effectiveness (up to and including the date of the GNTY Meeting), all information set forth in the Registration Statement that is or to be furnished by or on behalf of GBCI relating to GBCI and its Subsidiaries and by or on behalf of GNTY relating to GNTY and the Bank, (i) will comply in all material respects with the provisions of the Securities Act, the Exchange Act and any other applicable statutory or regulatory requirements, and (ii) will not contain any untrue statement of a material fact or omit to state a material fact that is required to be stated or necessary to make the statements in the Registration Statement not misleading; provided, however, that in no event will any party be liable for any untrue statement of a material fact or omission to state a material fact in the Registration Statement where such statement or omission, as the case may be, was made in reliance upon, and in conformity with, written information concerning another party furnished by or on behalf of such other party specifically for use in the Registration Statement.

(d) GBCI will pay all fees and costs associated with the preparation by GBCI’s counsel (and other professional advisors) and the filing of the Registration Statement. GNTY will pay all fees and costs associated with its review and preparation of the Registration Statement and printing and mailing of the Proxy Statement/Prospectus and the holding of the GNTY Meeting, with all such fees and costs to be included as and in the calculation of Transaction Related Expenses.

4.2.2 Submission to Shareholders. GNTY will promptly take the actions necessary in accordance with applicable Law and its certificate of formation and bylaws to convene a shareholders’ meeting to consider the approval of this Agreement and to authorize the transactions contemplated by this Agreement (such meeting and any adjournment or postponement thereof, the “GNTY Meeting”). The GNTY Meeting will be held as soon as reasonably practicable (but in any event within 45 days) after the date the Proxy Statement/Prospectus is sent to GNTY’s shareholders without objection by applicable Governmental Authorities. The board of directors of GNTY has adopted a resolution recommending approval of this Agreement and the Merger by GNTY’s shareholders, and it shall not withdraw, modify, or qualify its recommendation unless, subsequent to the Execution Date, GNTY receives a Superior Proposal and the board of directors of GNTY determines, in good faith and upon the written advice of independent legal counsel, that it would violate its fiduciary duties under applicable Law not to withdraw, modify, or qualify such recommendation. GNTY shall use its reasonable best efforts to obtain from GNTY’s shareholders approval of this Agreement in accordance with Texas Law, including (except as provided in the preceding sentence) by communicating to its shareholders its recommendation (and including such recommendation in the Proxy Statement/Prospectus) that they approve this Agreement and the Merger and, in GNTY’s sole discretion, retaining a proxy solicitor to assist with such communications. Subject to applicable Law, GNTY shall adjourn or postpone the GNTY Meeting if, as of the time for which such meeting is originally scheduled, there are insufficient shares of GNTY Stock 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 GNTY Meeting, (a) GNTY has not received proxies representing a sufficient number of shares necessary to obtain the required approval by GNTY’s shareholders and such approval remains possible to obtain and (b) the shareholders of GNTY have authorized by the requisite vote under Texas Law the adjournment pursuant to the Proxy Statement/Prospectus; provided that GNTY shall only be required to adjourn the GNTY Meeting two times pursuant to this Section 4.2.2.

- 52 -

4.3 Submission to Regulatory Authorities. GBCI will use its commercially reasonable efforts to promptly prepare, promptly file (but in any event within 45 days of the Execution Date) and timely effect all documentation, applications, notices, petitions and filings, and to obtain all permits, approvals, consents, authorizations, waivers, clearances and orders of Governmental Authorities necessary or advisable, in the opinion of GBCI’s counsel, to consummate the Transactions (the “Requisite Regulatory Approvals”), and to comply with the terms and conditions of all Requisite Regulatory Approvals. GBCI will provide to GNTY copies of all non-confidential portions of such documentation, applications, notices, petitions and filings for review and comment by GNTY prior to their submission to the applicable Governmental Authorities. These documentation, applications, notices, petitions and filings are expected to include (a) an interagency bank merger application to be filed with the FDIC, a waiver to be sought from the Federal Reserve, pursuant to Federal Reserve Regulation Y § 225.12(d) with respect to the Merger, and a notice to be provided to the OCC; (b) an application or notice to the Montana Commissioner and related filings regarding the Transactions; (c) a notice to be provided to the Texas Department of Banking, pursuant to §§ 202.001 and 203.003 of the TFC; (d) filings and coordination with the offices of the Secretaries of State of Montana and Texas with respect to the Merger; and (e) filings and coordination with the office of the Secretary of State of Montana and a notice provided to the OCC with respect to the Bank Merger. GNTY and the Bank will cooperate with GBCI and use their commercially reasonable efforts to assist GBCI in obtaining all Requisite Regulatory Approvals. GNTY and the Bank shall reasonably cooperate with GBCI and, upon request, furnish GBCI with all information concerning itself, and its directors, officers, and shareholders and such other matters as may be reasonably necessary or advisable in connection with any statement, filing, notice, or application made by or on behalf of GBCI, Glacier Bank, GNTY, or the Bank to any third party or Governmental Authority in connection with the Transactions.

4.4 Public Announcements. Subject to advice of legal counsel with respect to legal requirements relating to public disclosure of matters related to this Agreement and its subject matter, the timing and content of any announcements, press releases or other public statements concerning the Merger or the Bank Merger will occur upon, and be determined by, the mutual consent of GNTY and GBCI.

4.5 Consents. Each party to this Agreement will use its commercially reasonable efforts to obtain the timely consent or approval of any other Person whose consent or approval is necessary or appropriate in order to permit GBCI or GNTY and Glacier Bank or the Bank to consummate the Merger or the Bank Merger.

4.6 Transition.

4.6.1 Each of GBCI and GNTY shall designate an individual to serve as the primary representative tasked with coordinating transition matters with respect to the Transactions (each, a “Coordinator”). Each Coordinator shall have requisite authority to act on behalf of GBCI or GNTY, as applicable, in order to address reasonable requests of the other during the transition period.

- 53 -

4.6.2 At such times as GBCI’s Coordinator may reasonably request during the period from the Execution Date to the Effective Time, the Coordinators shall meet for the purposes of discussing (i) the general status of GNTY’s ongoing operations; (ii) the recipients, amounts and timing of payment of retention bonuses to Employees, including whether such bonuses will be paid contingent upon retention through Closing, core systems conversion, or upon another agreed-upon milestone; and (iii) the plan for the conversion of the Bank’s data processing and related electronic informational systems to those used by GBCI and Glacier Bank, which planning shall include, but not be limited to, discussion of the possible termination by the Bank of third-party service provider arrangements effective at the Effective Time or at a date thereafter, non-renewal of personal property leases and software licenses used by the Bank in connection with its systems operations, retention of outside consultants and additional employees to assist with the conversion, and outsourcing, as appropriate, of proprietary or self-provided system services, it being understood that neither GNTY nor the Bank shall be obligated to take any formal action to take effect prior to the Effective Time; provided, however, no such request by GBCI’s Coordinator shall interfere materially with the performance of duties by any employee of GNTY or the Bank.

4.6.3 GNTY shall use commercially reasonable efforts to provide to GBCI (i) a preliminary test file for core systems conversion that includes a preliminary tape and set of deconversion reports within 45 days after the Execution Date; and (ii) updated versions of such preliminary test file within five Business Days of GBCI’s reasonable request to GNTY.

4.7 Notice of Certain Events; Cooperation. GBCI and GNTY will each provide the other with prompt written notice of: (a) any events that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect with respect to it, (b) the commencement of any investigation, action or proceeding against it by or before any court or Governmental Authority that would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect with respect to it, and (c) any shareholder or other litigation or community-based protests, or any threat of such litigation or protest, against such party or its directors relating in any manner to this Agreement or the transactions contemplated hereby and shall keep the other party reasonably informed regarding any such shareholder or other litigation or protests, or threat related thereto, including providing all relevant documentation reasonably requested. No settlement of any litigation referenced in clause (c) shall be agreed to without GBCI’s prior written consent. The parties will reasonably cooperate with each other in all material respects between the Execution Date and Closing to resolve any fact or circumstance identified by a party that would give rise to a breach of any of the representations, warranties, agreements or covenants in this Agreement if such facts or circumstances had been present as of the Execution Date. In addition, GNTY will notify GBCI in the event it or any GNTY Subsidiary acquires a fee ownership or leasehold interest in any real property. Notwithstanding anything in this Section 4.7 to the contrary, a failure to provide notice pursuant to this Section 4.7 shall not, in and of itself, result in a failure of any condition to the obligation of any party to consummate the Merger pursuant to Article 5 unless the underlying event would independently result in a failure to meet any such condition.

4.8 Confidentiality. Subject to the requirements of Law, each party will keep and hold as confidential, and will exercise commercially reasonable efforts to cause its representatives to keep and hold as confidential, all information and documents obtained pursuant to this Agreement unless such information (a) is required by Law to be disclosed, (b) becomes available to such party from other sources not bound by a confidentiality obligation, (c) is disclosed with

- 54 -

prior written approval of the party to which such information pertains or is disclosed in a legal action between the parties relating to this Agreement or the Transactions, or (d) is or becomes public without fault of the subject party. If this Agreement is terminated or the Merger otherwise fails to be consummated, each party to this Agreement will remain bound by the terms of the Confidentiality Agreement, which will continue in accordance with its terms.

4.9 Listing. Prior to the Effective Time, GBCI shall cause to be filed with the NYSE such notices of issuance or related forms as may be necessary or appropriate in connection with issuance of the GBCI Shares in the Merger.

4.10 Blue Sky Filings. GBCI will use commercially reasonable efforts to obtain, prior to the mailing of the Registration Statement, any necessary state securities Laws or “Blue Sky” permits and approvals.

4.11 Tax Treatment. Neither GBCI and its Subsidiaries nor GNTY and the GNTY Subsidiaries will take or cause to be taken any action that would reasonably be expected to prevent the Merger from qualifying as a reorganization under IRC Section 368(a). Each of GBCI and its Subsidiaries and GNTY and the GNTY Subsidiaries shall use commercially reasonable efforts to cause the Merger to qualify as a reorganization under IRC Section 368(a). The parties shall report the Merger for all U.S. federal, state, and local income Tax purposes in a manner consistent with qualification as a reorganization under IRC Section 368(a). GBCI shall comply with the recordkeeping and information reporting requirements set forth in Treasury Regulations § 1.368-3.

4.12 GNTY Closing Capital. No earlier than the 15th Business Day prior to the anticipated date of Closing (the “Anticipated Closing Date”) nor later than the 11^th Business Day before the Anticipated Closing Date, GNTY shall calculate and provide to GBCI the estimated GNTY Capital as of the Anticipated Closing Date (including estimated earnings through the Anticipated Closing Date) determined in accordance with GAAP or otherwise as expressly provided in this Agreement, and shall provide GBCI with a copy of the proposed Subsequent GNTY Financial Statements and Subsequent Bank Financial Statements for the month preceding the date of calculation (if not already provided in accordance with Section 4.1.6), together with internally prepared financial statements through the date of calculation, estimated retained earnings through the Anticipated Closing Date, the impact of any pending adjustments required in the calculation of the estimated GNTY Capital, and any other documentation reasonably requested by GBCI for purposes of confirming the amount of such estimated GNTY Capital. GBCI shall review such materials and, within four Business Days following receipt thereof, notify GNTY as to whether GBCI accepts or disputes the amount of the estimated GNTY Capital. If GBCI disputes such calculation, it shall describe in its notice its specific requested changes or adjustments. If GBCI and GNTY are unable to resolve such dispute through good faith negotiations within three Business Days after delivery of GBCI’s notice of objection, then the parties shall mutually engage and submit such dispute to, and the same shall be finally resolved by, an accounting firm that is mutually and reasonably acceptable to, and independent of, the parties (the “Independent Accountants”). The Independent Accountants shall review the matter in dispute and, solely as to disputes relating to accounting issues and acting as an expert and not as an arbitrator, determine and report in writing to GBCI and GNTY the resolution of such disputed matters and the effect of such determinations on the calculation of the GNTY

- 55 -

Capital estimated as of the Anticipated Closing Date (unadjusted for any delay that may have been caused by the Independent Accountants’ review of the matter(s) in dispute), and such determinations shall be final, binding and conclusive unless GBCI and GNTY mutually agree upon a different amount. The GNTY Capital estimated as of the Anticipated Closing Date, as determined and agreed upon in writing by GBCI and GNTY in accordance with this Section 4.12, is the “GNTY Closing Capital.” The fees and disbursements of the Independent Accountants pursuant to this Section 4.12 and Section 4.13 below shall be shared equally by GBCI, on the one hand, and GNTY, on the other hand, and GNTY’s portion shall be an expense in the calculation of the GNTY Closing Capital.

4.13 Transaction Related Expenses. No earlier than the 15th Business Day prior to Closing nor later than the 11th Business Day before such Closing, GNTY shall calculate in good faith the estimated Transaction Related Expenses as of the Closing and shall provide GBCI with a copy of a schedule in the form of Exhibit B detailing each Transaction Related Expense and any other documentation reasonably requested by GBCI for purposes of confirming the amount of such Transaction Related Expenses. GBCI shall review such materials and, within four Business Days following receipt thereof, notify GNTY as to whether GBCI accepts or disputes the amount of the estimated Transaction Related Expenses. If GBCI disputes such calculation in good faith, it shall describe in its notice its specific requested changes or adjustments. If GBCI and GNTY are unable to resolve such dispute through good faith negotiations within four Business Days after delivery of GBCI’s notice of objection, then the parties shall mutually engage and submit such dispute to, and the same shall be finally resolved by the Independent Accountants in accordance with the process set forth in Section 4.12. The Transaction Related Expenses estimated as of Closing, as determined and agreed upon in writing by GBCI and GNTY in accordance with this Section 4.13, are the “Final Transaction Related Expenses.”

4.14 Payment of Dividend; Adjustment to Per Share Stock Consideration.

4.14.1 Payment of Dividend; Notice; Adjustment to Dividend. If the GNTY Closing Capital exceeds the Closing Capital Requirement (i.e., the Closing Capital Differential is a positive number) after making all adjustments required by the terms of this Agreement (including, without limitation, in the event the Final Transaction Related Expenses exceed the Maximum Transaction Expense Amount), GNTY may, upon prior written notice to GBCI not less than 12 calendar days prior to the Anticipated Closing Date, declare a special dividend to its shareholders of record on a date prior to the Anticipated Closing Date reasonably determined by GNTY and payable on or before the Effective Date in an aggregate amount equal to the positive Closing Capital Differential. The special dividend payable pursuant to this Section 4.14.1 shall be allocated to such GNTY shareholders of record and holders of GNTY Options in accordance with Schedule 1.4.1(b). GNTY shall satisfy all notice requirements to Governmental Authorities applicable to payment of the special dividend pursuant to this Section 4.14.1 and issue a press release, if reasonably requested by GBCI.

4.14.2 Adjustment to Per Share Stock Consideration. If the GNTY Closing Capital is less than the Closing Capital Requirement (i.e., the Closing Capital Differential is a negative number) after making all adjustments required by the terms of this Agreement (including, without limitation, in the event the Final Transaction Related Expenses exceed the Maximum Transaction Expense Amount), then the Per Share Stock Consideration will be reduced on a per share basis by an amount, rounded to the nearest ten thousandth (referred to as the “Stock Consideration Per Share Adjustment Amount”), determined by dividing the remaining balance in the negative Closing Capital Differential by the GBCI Average Closing Price, and dividing that result by the number of shares of GNTY Stock outstanding at the Effective Time.

- 56 -

The parties acknowledge and agree that (a) the agreements contained in Section 7.3 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, neither party would enter into this Agreement, and (b) any amount payable by GNTY pursuant to Section 7.3 constitutes liquidated damages and not a penalty and shall be the sole monetary remedy of GBCI in the event of termination of this Agreement under circumstances that give rise to payment of the Break-Up Fee. In the event that GNTY fails to pay the Break-Up Fee when due then (a) GNTY shall reimburse GBCI for all costs and expenses (including disbursements and reasonable fees of counsel) incurred in connection with the collection of unpaid or overdue amounts, and (b) GNTY shall pay to GBCI interest on such overdue amounts (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) at a rate per annum equal to the prime rate published in The Wall Street Journal on the date such payment was required to be made, plus 2 percent. The parties hereto acknowledge and agree that in no event shall GNTY be required to pay the Break-Up Fee more than one time.

8.5 Expenses, Fees and Costs. Except as otherwise specifically provided herein, all fees, costs and expenses (including all legal, accounting, broker, finder or investment banker fees) incurred in connection with this Agreement and the Transactions are to be paid by the party incurring such fees, costs and expenses. In the event of any dispute, claim, arbitration or litigation arising out of or in connection with, or relating to, this Agreement or any breach or alleged breach of this Agreement (“Claim”), the substantially prevailing party on any such Claim will be entitled to reimbursement from the other party of its costs and expenses, including reasonable attorneys’ fees.

8.6 Arbitration. At either party’s request, the parties must submit any Claim to arbitration under the American Arbitration Association’s Commercial Arbitration Rules then in effect (or under any other form of arbitration mutually acceptable to the parties); provided that a party shall not be prevented from seeking injunctive relief from a court of competent jurisdiction in accordance with Sections 8.7 and 8.10 below to enforce this Agreement. A single arbitrator agreed on by the parties will conduct any arbitration. If the parties cannot agree on a single arbitrator within 15 days after service of the demand for arbitration, Claims shall be heard by a panel of three arbitrators, selected as follows: each party shall select one person to act as arbitrator and the two selected shall select a third arbitrator within 10 days of their appointment; if the arbitrators selected by the parties fail to select or are unable to agree on the third arbitrator, the third arbitrator shall be selected by the American Arbitration Association. The arbitration decision is final (except as otherwise specifically provided by ▇▇▇) and binds the parties, and either party may request any court having jurisdiction to enter a judgment and to enforce the arbitrator’s decision. The arbitrator(s) will provide the parties with a written decision naming the substantially prevailing party in the action. Any arbitration or related proceedings will take place in Kalispell, Montana.

Therefore, the parties shall be entitled to seek specific performance of the terms of this Agreement, in addition to any other remedies to which they are entitled at law or equity. Each party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other parties have an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties acknowledge and agree that any party entitled to an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such injunction, and any party against whom such injunction is entered expressly waives any bond or security in connection therewith.

EXHIBIT B

Form of Transaction-Related Expenses Exhibit

As provided in the Plan and Agreement of Merger, to the extent Final Transaction Related Expenses exceed the Maximum Transaction Expense Amount, the difference, on an after-tax basis (applying an effective tax rate of 21.0 percent to reflect proportionately items that are deductible under applicable Tax Laws to those that are not), will be treated as a reduction of GNTY Capital for purposes of determining GNTY Closing Capital (regardless of whether such amounts are required to be expensed in accordance with GAAP). If Final Transaction Related Expenses are less than the Maximum Transaction Expense Amount, the difference, on an after-tax basis (applying an effective tax rate of 21.0 percent to the extent a particular item is deductible under applicable Tax Laws), will be treated as an increase in GNTY Capital for such purpose.

*Figures to be provided prior to giving effect to taxes.
