Item 1.01. Entry Into a Material Definitive Agreement.

Entry Into Agreement and Plan of Reorganization with Guaranty Bancorp

On May 22, 2018, Independent Bank Group, Inc. (“Independent”) entered into an Agreement and Plan of Reorganization (the “Agreement”) with Guaranty Bancorp, a Delaware corporation (“Guaranty”), pursuant to which Guaranty would merge with and into Independent and Independent would continue as the surviving entity (the “Merger”), subject to the terms and conditions set forth therein. Subsequent to the Merger, Independent would merge Guaranty Bank and Trust Company, a Colorado state bank and wholly owned subsidiary of Guaranty, with and into Independent Bank, a Texas state banking association and wholly owned subsidiary of Independent, with Independent Bank continuing as the surviving bank.

Under the terms of the Agreement, shareholders of Guaranty will receive 0.45 shares of Independent common stock for each share of Guaranty common stock. The aggregate consideration is valued at approximately $1.0 billion, or approximately $35.37 per Guaranty share, based on the closing price of Independent’s common stock of $78.60 on May 21, 2018. In addition, the Agreement provides that Paul W. Taylor, President and Chief Executive Officer of Guaranty, and Edward B. Cordes, Chairman of the Board of Guaranty, will be added to the Independent Board upon consummation of the Merger.

The Merger is currently expected to be consummated during the fourth quarter of 2018. Completion of the Merger is subject to customary conditions, including (i) the effectiveness of Independent’s Registration Statement on Form S-4 registering the Independent shares to be issued in connection with the Merger, which registration statement will be filed with the Securities and Exchange Commission (“SEC”), (ii) the receipt of bank regulatory approvals, (iii) approval of Independent’s shareholders and Guaranty’s stockholders, and (iv) the satisfaction of other customary closing conditions. The Merger has been approved by the Boards of Directors of Independent and Guaranty.

The foregoing summary of the terms of the Agreement is not complete and is qualified in its entirety by reference to the complete text of the Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

On May 22, 2018, Independent posted on the Investor Relations page of its website a slide presentation related to the proposed Merger with Guaranty. A copy of the slide presentation is furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

Independent and Guaranty issued a joint press release on May 22, 2018, to announce the proposed Merger, a copy of which press release is furnished as Exhibit 99.2 to this Current Report on Form 8-K and incorporated herein by reference.

In accordance with the General Instruction B.2 of Form 8-K, the information in Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 and Exhibit 99.2 hereto, which is furnished herewith pursuant to and relate to Item 7.01, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of Section 18 of the Exchange Act. The information in Item 7.01 of this Current Report on Form 8-K and Exhibit 99.1 and Exhibit 99.2 hereto shall not be incorporated by reference into any filing or other document filed by Independent with the SEC pursuant to the Securities Act of 1933, as amended (the “Securities Act”), the rules and regulations of the SEC thereunder, the Exchange Act, or the rules and regulations of the SEC thereunder, except as shall be expressly set forth by specific reference in such filing or document.

Special Note Regarding the Agreement

The Agreement contains customary representations, warranties, covenants and other terms, provisions and conditions that Independent and Guaranty made to each other as of specific dates. The assertions embodied in those terms, provisions and conditions were made solely for purposes of the Agreement, and may be subject to important qualifications and limitations agreed to by the parties to the Agreement in connection with negotiating the terms contained in the Agreement. Moreover, the parties to the Agreement may be subject to a contractual standard of materiality in the Agreement that may be different from what may be viewed as material to shareholders of Independent or Guaranty or may have been used by the parties for the purpose of allocating risk between Independent, together with its direct and indirect subsidiaries, and Guaranty, together with its direct and indirect subsidiaries, rather than for the purpose of establishing matters as facts. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding Independent or Guaranty at the time they were made or otherwise.

Forward Looking Statements

Certain statements contained in this filing and related presentations that are not statements of historical fact constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties and are made pursuant to the safe harbor provisions of Section 27A of the Securities Act and Section 21E of the Exchange Act. These forward-looking statements include information about Independent Bank Group’s and Guaranty Bancorp’s possible or assumed future economic performance or future results of operations, including Independent Bank Group’s or Guaranty Bancorp’s future revenues, income, expenses, provision for loan losses, provision for taxes, effective tax rate, earnings per share and cash flows, and Independent Bank Group’s and Guaranty Bancorp’s future capital expenditures and dividends, future financial condition and changes therein, including changes in Independent Bank Group’s and Guaranty Bancorp’s loan portfolio and allowance for loan losses, future capital structure or changes therein, as well as the plans and objectives of management for Independent Bank Group’s and Guaranty Bancorp’s future operations, future or proposed acquisitions, the future or expected effect of acquisitions on Independent Bank Group’s and Guaranty Bancorp’s operations, results of operations, financial condition, and future economic performance, statements about the benefits of the proposed transaction, and the

statements of the assumptions underlying any such statement. Such statements are typically, but not exclusively, identified by the use in the statements of words or phrases such as “aim”, “anticipate”, “estimate”, “expect”, “goal”, “guidance”, “intend”, “is anticipated”, “is expected”, “is intended”, “objective”, “plan”, “projected”, “projection”, “will affect”, “will be”, “will continue”, “will decrease”, “will grow”, “will impact”, “will increase”, “will incur”, “will reduce”, “will remain”, “will result”, “would be”, variations of such words or phrases (including where the word “could”, “may”, or “would” is used rather than the word “will” in a phrase) and similar words and phrases indicating that the statement addresses some future result, occurrence, plan or objective. The forward-looking statements that Independent Bank Group and Guaranty Bancorp make are based on our current expectations and assumptions regarding Independent Bank Group’s and Guaranty Bancorp’s businesses, the economy, and other future conditions. Because forward-looking statements relate to future results and occurrences, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. Many possible events or factors could affect Independent Bank Group’s or Guaranty Bancorp’s future financial results and performance and could cause those results or performance to differ materially from those expressed in the forward-looking statements. Such risks and uncertainties include, among others: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between Independent Bank Group and Guaranty Bancorp, the outcome of any legal proceedings that may be instituted against Independent Bank Group or Guaranty Bancorp, delays in completing the transaction, the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction) and shareholder approvals or to satisfy any of the other conditions to the transaction on a timely basis or at all, the possibility that the anticipated benefits of the transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Independent Bank Group and Guaranty Bancorp do business, the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, diversion of management’s attention from ongoing business operations and opportunities, potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the transaction, Independent Bank Group’s ability to complete the acquisition and integration of Guaranty Bancorp successfully, and the dilution caused by Independent Bank Group’s issuance of additional shares of its common stock in connection with the transaction. Each of Independent Bank Group and Guaranty Bancorp disclaims any obligation to update such factors or to publicly announce the results of any revisions to any of the forward-looking statements included herein to reflect future events or developments. Further information on Independent Bank Group, Guaranty Bancorp, and factors which could affect the forward-looking statements contained herein can be found in Independent Bank Group’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, its Quarterly Report on Form 10-Q for the three-month period ended March 31, 2018 and its other filings with the SEC, and in Guaranty Bancorp’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, its Quarterly Report on Form 10-Q for the three-month period ended March 31, 2018 and its other filings with the SEC.

At the Effective Time, all rights, title and interests to all real estate and other property owned by GBNK shall be allocated to and vested in the Resulting Corporation without reversion or impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any existing liens or encumbrances thereon.

Section 1.05.    Conversion of GBNK Shares. At the Effective Time by virtue of this Agreement and without any action on the part of IBG, GBNK or the holder of any of the following securities:

For purposes of this Section 1.06(B), the number of GBNK Shares subject to each GBNK 2015 RSA for which the performance period is not completed as of the Effective Time shall be the target number of GBNK Shares subject to such GBNK 2015 RSA.

IBG shall consider in good faith all comments from GBNK and its legal, financial and accounting advisors to the Registration Statement, all amendments and supplements thereto and all responses to requests for additional information. GBNK agrees to reasonably cooperate with IBG and IBG’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and independent auditor and in taking such other required actions in connection with the Registration Statement and the Proxy Statement. If GBNK has reasonably cooperated and promptly provided information required to be delivered by it for inclusion in the Registration Statement and Proxy Statement as required by this Section 1.08(A) and Section 5.02, IBG shall file, or cause to be filed, the Registration Statement with the SEC on or before the sixtieth (60th) day following the date of this Agreement. IBG shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act of 1933, as amended (the “Securities Act”), as promptly as reasonably practicable after the filing thereof.

GBNK shall prepare and deliver (at its expense) the Proxy Statement to its stockholders as promptly as practicable after the date that the Registration Statement is declared effective and a final prospectus (relating to the Registration Statement) and Proxy Statement is on file with the SEC before such mailing, and shall hold the GBNK Meeting as promptly as practicable thereafter and in any event on or before the sixtieth (60th) day after the date that the Registration Statement is declared effective. Except as otherwise set forth in Section 1.08(C), neither GBNK nor the GBNK Board nor any committee thereof shall (i) withhold, withdraw or modify in any manner adverse to IBG or propose publicly to withhold, withdraw or modify in any manner adverse to IBG, the GBNK Board Recommendation or approval, recommendation or declaration of advisability by GBNK, the GBNK Board or any such committee thereof with respect to this Agreement or the transactions contemplated hereby, (ii) approve or recommend to its stockholders, or resolve to or publicly propose or announce its intention to approve or recommend to its stockholders, an Acquisition Proposal or (iii) fail to publicly, finally and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the GBNK Board Recommendation, in each case, within 10 Business Days after such Acquisition Proposal is made public or any request by IBG to do so (which request may be made once per Acquisition Proposal (and any material change thereto)) (any of the foregoing, a “GBNK Change in Recommendation”).

-5-

(C)    Notwithstanding the foregoing, prior to the receipt of the Requisite GBNK Stockholder Approval, GBNK and the GBNK Board are permitted to make a GBNK Change in Recommendation if and only to the extent that:

(2)    an unsolicited bona fide written Acquisition Proposal (that did not result from a breach of Section 5.10) is made to GBNK by a third party, and such Acquisition Proposal is not withdrawn;

(3)    the GBNK Board, after consultation with its outside counsel, has determined in good faith, after giving effect to all of the adjustments which may be offered by IBG pursuant to subclause (c) of item (4) below, that failure to make a GBNK Change in Recommendation would reasonably be expected to be inconsistent with the GBNK Board’s fiduciary duties under applicable Law; and

(4)    (a) the GBNK Board has concluded in good faith, after giving effect to all of the adjustments which may be offered by IBG pursuant to subclause (c) below, that such Acquisition Proposal constitutes a Superior Proposal, (b) GBNK has notified IBG, at least five Business Days in advance, of its intention to make a GBNK Change in Recommendation in response to such Superior Proposal (including the identity of the party making such Acquisition Proposal) and furnished to IBG a written description of the material terms of the Superior Proposal, and (c) before making such a GBNK Change in Recommendation, GBNK has, and has caused its financial and legal advisors to, during the period after GBNK’s delivery of the notice referred to in subclause (b) above, negotiated with IBG in good faith for a period of up to five Business Days (to the extent IBG desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal. Any change to the material terms of an Acquisition Proposal shall require a new notice of GBNK’s intention to make a GBNK Change in Recommendation and the provisions of this Section 1.08(C) shall apply anew to such Acquisition Proposal.

(D)    The Board of Directors of IBG (the “IBG Board”) shall duly call, give notice of, and cause to be held, a meeting of its shareholders (the “IBG Meeting”) and will direct that this Agreement and the transactions contemplated hereby be submitted to a vote at the IBG Meeting. Specifically, the IBG Board will present for the consideration of IBG shareholders a proposal to approve and adopt this Agreement and the Merger and the transactions contemplated hereby and the issuance of IBG Shares in connection with the Merger.

IBG shall print and commence the mailing (at its expense) of the Proxy Statement to its shareholders as promptly as practicable after the date that the Registration Statement is declared effective and a final prospectus (relating to the Registration Statement) and Proxy Statement is on file with the SEC

before such mailing, and shall hold the IBG Meeting as promptly as practicable thereafter and in any event on or before the sixtieth (60th) day after the date that the Registration Statement is declared effective. Neither IBG nor the IBG Board nor any committee thereof shall withhold, withdraw or modify in any manner adverse to GBNK or propose publicly to withhold, withdraw or modify in any manner adverse to GBNK, the IBG Board Recommendation or approval, recommendation or declaration of advisability by IBG, the IBG Board or any such committee thereof with respect to this Agreement or the transactions contemplated hereby.

(E)    Nothing contained in this Section 1.08 shall prohibit GBNK from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder; provided, however, that compliance with such rules shall not in any way limit or modify the effect that any action taken pursuant to such rules has under any other provision of this Agreement; provided, further, that any such disclosure (other than a “stop, look and listen” statement pending disclosure of its position thereunder, which is followed within 10 Business Days by an unqualified public reaffirmation of the GBNK Board Recommendation) shall be deemed for all purposes of this Agreement to be a GBNK Change in Recommendation unless the GBNK Board expressly publicly reaffirms without qualification the GBNK Board Recommendation in connection with such communication.

Section 1.09.    Effective Time. The “Effective Time” means the effective time of the Merger as specified in the certificate of merger to be filed with the Texas Secretary of State and the certificate of merger to be filed with the Secretary of State of the State of Delaware, respectively, on the Closing Date, which shall be 12:01 a.m. on the first day of the calendar month immediately following the calendar month in which the Closing Date occurs.

Section 1.10.    Bank Merger. Immediately after the Effective Time, IBG shall cause the Bank Merger to be consummated.

Section 1.11.    Anti-Dilution Provisions. If, between the date of this Agreement and the Effective Time, the IBG Shares or GBNK Shares are changed, or if the IBG Board sets a related record date that will occur before the Effective Time for a change, into a different number or class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment, or a share dividend thereon is declared with a record date within said period, an appropriate and proportionate adjustment shall be made to the Merger Consideration, the Exchange Ratio and any dependent items (including those set forth in Section 9.01(I)), to provide to the GBNK stockholders the same economic effect as contemplated by this Agreement prior to such action; provided, however, that nothing in this sentence shall be construed to permit any party to take any action with respect to its securities that is prohibited by the terms of this Agreement.

Section 1.12.    Tax Matters.

(A)    None of IBG, Independent Bank, GBNK or Guaranty Bank has taken or agreed to take any action, or is aware of any fact or circumstance, that could reasonably be expected to prevent the Merger from qualifying as a reorganization within the meaning of § 368

(A)    On the Business Day before the Closing Date, IBG shall deposit or cause to be deposited in trust with Equiniti Trust Company or another bank or trust company mutually agreeable to IBG and GBNK (the “Exchange Agent”), for the benefit of the holders of the GBNK Shares (i) certificates for shares or, at IBG’s option, evidence of shares in book entry form, including via the direct registration system (collectively, referred to herein as “certificates”) representing the aggregate number of IBG Shares which the holders of GBNK Shares are entitled to receive pursuant to Section 1.05 and (ii) any cash payable in lieu of fractional shares pursuant to Section 1.05(C) (such IBG Shares and cash described in the foregoing clauses (i) and (ii), “Exchange Fund”).

(B)    As soon as practicable after the Effective Time, but in no event more than five Business Days after the Effective Time, the Resulting Corporation shall use commercially reasonable efforts to cause the Exchange Agent to mail to each record holder of an outstanding certificate or certificates representing GBNK Shares (each, a “Certificate”, it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry accounts relating to the ownership of GBNK Shares), a form letter of transmittal which will specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and contain instructions for use in effecting the surrender of the Certificates for payment therefor. IBG shall provide a draft of the form of letter of transmittal to GBNK no later than 10 days prior to the Closing Date. The form and substance of the letter of transmittal and any associated cover letter shall be mutually acceptable to IBG and GBNK before such transmittal materials are mailed to the holders of the Certificates. Upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal properly completed and duly executed (the “Transmittal Materials”), the holder of such Certificate shall be entitled to receive in exchange therefor (i) a certificate representing that number of IBG Shares equal to the product of (x) the Exchange Ratio, multiplied by (y) the number of GBNK Shares represented by the Certificate, and (ii) an amount of cash as payment in lieu of the issuance of fractional IBG Shares calculated in accordance with Section 1.05(C), and such Certificate shall forthwith be canceled. Until surrendered in accordance with this Section 2.04, each Certificate (other than Certificates representing Cancelled Shares) shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration without any interest thereon. Promptly after receipt of the Transmittal Materials, the Resulting Corporation will use commercially reasonable efforts to cause the Exchange Agent to review the Transmittal Materials in order to verify proper completion and execution thereof. As soon as practicable after the Effective Time and the surrender of a Certificate to the Exchange Agent, together with properly completed and executed Transmittal Materials, the Resulting Corporation will use commercially reasonable efforts to cause the Exchange Agent to promptly deliver the Merger Consideration.

-11-

(C)    After the Effective Time, the share transfer ledger of GBNK shall be closed and there shall be no transfers on the share transfer books of GBNK of the GBNK Shares which were outstanding immediately before such time of filing. If, after the Effective Time, Certificates are presented to the Resulting Corporation, they shall be promptly presented to the Exchange Agent and exchanged as provided in this Section 2.04.

(D)    No dividends or other distributions declared after the Effective Time with respect to IBG Shares and payable to the holders thereof shall be paid to the holder of a Certificate until such holder surrenders such Certificate to the Exchange Agent in accordance with this Section 2.04. After the surrender of a Certificate in accordance with this Section 2.04, the holder thereof shall be entitled to receive any such dividends or other distributions, without interest thereon, which had become payable after the Effective Time with respect to the IBG Shares represented by such Certificate.

(E)    Any portion of the Exchange Fund that remains unclaimed by the stockholders of GBNK for twelve months after the Exchange Agent mails the letter of transmittal pursuant to this Section 2.04 shall be delivered to the Resulting Corporation upon demand, and any stockholders of GBNK who have not theretofore complied with the exchange procedures in this Section 2.04 shall look to the Resulting Corporation only, and not the Exchange Agent, for the payment of the Merger Consideration in respect of such shares. If outstanding Certificates for GBNK Shares are not surrendered or the payment for them is not claimed before the date on which such IBG Shares or cash would otherwise escheat to any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property or any other applicable Law, become the property of the Resulting Corporation (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property.

(F)    If any IBG Shares are to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be appropriately endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form (reasonably satisfactory to the Resulting Corporation) for transfer, and that the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the issuance of a certificate representing IBG Shares in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or not payable. The Exchange Agent, IBG or the Resulting Corporation shall be entitled to deduct and withhold from any portion of the Merger Consideration or other consideration payable under this Agreement such amounts as the Exchange Agent, IBG or the Resulting Corporation, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign tax Law, with respect to the making of such payment.

(A)    Each of GBNK and its Subsidiaries has good and marketable title to all securities held by it in all material respects (except securities sold under repurchase agreements or held in any fiduciary or agency capacity) free and clear of any Lien, except to the extent that such securities are pledged in the ordinary course of business consistent with prudent business practices to secure obligations of GBNK or any of its Subsidiaries and except for such defects in title or Liens that would not be material to GBNK and its Subsidiaries, taken as a whole. Such securities are valued on the books of GBNK and each of its Subsidiaries in accordance with GAAP in all material respects.

-32-

(B)    GBNK and each of its Subsidiaries employs investment, securities risk management and other policies, practices and procedures that GBNK and each such Subsidiary believes are prudent and reasonable in the context of such businesses, and GBNK and its Subsidiaries have, since January 1, 2016, been in material compliance with such policies, practices and procedures in all material respects.

Section 3.37.    Risk Management Instruments. Except as otherwise set forth in Confidential Schedule 3.37, neither GBNK nor any GBNK Subsidiary is a party to nor has it agreed to enter into an exchange traded or over-the-counter equity, interest rate, foreign exchange or other swap, forward, future, option, cap, floor or collar or any other contract that is a derivatives contract (including various combinations thereof), other than those entered into in the ordinary course of business and in accordance with applicable Laws and with counterparties believed to be financially responsible, all of which are legal, valid and binding obligations of GBNK or its applicable Subsidiary, enforceable against GBNK or such Subsidiary in accordance with their respective terms and conditions, except as enforceability may be limited by bankruptcy, conservatorship, insolvency, moratorium, reorganization, receivership or similar Laws and judicial decisions affecting the rights of creditors generally and by general principles of equity (whether applied in a proceeding at law or in equity), and GBNK and its applicable Subsidiaries and, to GBNK’s Best Knowledge, each counterparty thereto, have duly performed in all material respects all of their material obligations thereunder.

Section 3.38.    Indemnification. To the Best Knowledge of GBNK, no action or failure to take action by any present or former director, officer, employee or agent of GBNK or any GBNK Subsidiary has occurred which would give rise to a material claim by any such individual for indemnification from GBNK or any GBNK Subsidiary.

Section 3.39.    Organization and Qualification of the Trusts. GBNK has two special purpose trust subsidiaries, CenBank Statutory Trust III (“CenBank Trust”) and Guaranty Capital Trust III (“Guaranty Trust”, and, together with the CenBank Trust the “Trusts”). With respect to the Trusts:

(A)    (i) CenBank Trust has issued and sold preferred securities (the “CenBank Preferred Securities”) and common securities (the “CenBank Common Securities”) under an Amended and Restated Trust Agreement (the “CenBank Trust Agreement”) and GBNK has issued to CenBank Trust Floating Rate Junior Subordinated Debentures (the “CenBank Debentures”), under an Indenture (CenBank Trust’s Indenture and the CenBank Trust Agreement are collectively referred to as the “CenBank Trust Operative Documents”) and (ii) Guaranty Trust has issued and sold capital securities (the “Guaranty Trust Capital Securities”) and common securities (the “Guaranty Trust Common Securities”) under an Amended and Restated Declaration of Trust (the “Guaranty Trust Agreement”, and, together with the CenBank Trust Agreement, the “Trust Agreements”), and GBNK has issued to the Guaranty Trust, Junior Subordinated Debentures (the “Guaranty Trust Debentures”, and, together with the CenBank Debentures, the “Debentures”), under an Indenture (Guaranty Trust’s Indenture and the Guaranty Trust Agreement are collectively referred to, together with the CenBank Trust Operative Documents, the “Operative Documents”). Confidential Schedule 3.39 sets forth, with respect to the Trusts, the (i) dates of the respective Operative Documents, (ii) aggregate liquidation value of the CenBank Preferred Securities, CenBank Common Securities, Guaranty Trust Capital

-33-

Securities and Guaranty Trust Common Securities (together, the “Trust Securities”), (iii) aggregate amount of Debentures that have been issued to each Trust by GBNK, (iv) the rate paid on the respective Trust Securities and the Debentures (collectively, the “Securities”), (v) the dates after which GBNK may redeem the respective Debentures at par, and (vi) the maturity date of the respective Debentures.

(B)    The Trusts have been duly created and each is validly existing in good standing as a statutory trust under the Laws of the State of Delaware with the power and authority to own property and to conduct the business it transacts and proposes to transact and to enter into and perform its obligations under the Operative Documents. Each Trust is not a party to or otherwise bound by any material agreement other than the Operative Documents and a Placement Agreement of even date with the Trust Agreement. Each Trust is and will, be classified for tax purposes as a grantor trust and not as an association taxable as a corporation.

(C)    The Trust Securities have been duly authorized by the respective Trust Agreements, have been validly issued and represent undivided beneficial interests in the assets of the respective Trusts. None of the Trust Securities is subject to preemptive or other similar rights. All of the outstanding CenBank Common Securities and Guaranty Trust Common Securities (the “Common Securities”) are directly owned by GBNK free and clear of any pledge, security interest, claim, Lien or other encumbrance, and have been issued in compliance with applicable federal and state securities Laws. The Common Securities satisfy the eligibility requirements of Rule 144A(d)(3) issued under the Securities Act. Neither GBNK nor any Trust is an “investment company” or an entity “controlled” by an “investment company,” in each case within the meaning of Section 3(a) of the Investment Company Act of 1940, as amended, without regard to Section 3(c) of that act. The Debentures are not held of record by stockholders of GBNK or any GBNK Subsidiary.

(D)    The sole assets of each Trust are its Debentures, any interest paid on such Debentures to the extent not distributed, proceeds of such Debentures, or any of the foregoing.

(E)    All of the proceeds from the sale of the CenBank Preferred Securities and the Guaranty Trust Capital Securities issued by each respective Trust have been invested in its respective Debentures. All of the proceeds from the sale of the Common Securities issued by each respective Trust have been invested in the respective Debentures. All Debentures are and have been held by each Trust since their initial issuance.

(F)    Neither Trust was not formed to, and is not authorized to, conduct any trade or business and neither Trust has conducted any trade or business since it was formed. The Trusts exist for the exclusive purposes of (i) issuing and selling its respective CenBank Preferred Securities and the Guaranty Trust Capital Securities, as applicable, and its respective Common Securities, (ii) using the proceeds from the sale of its respective CenBank Preferred Securities and the Guaranty Trust Capital Securities, as applicable, and its respective Common Securities to acquire its respective Debentures, and (iii) engaging only in activities necessary, advisable or incidental thereto. Each Trust was formed to facilitate direct investment in the assets of such Trust, and the existence of multiple classes of ownership is incidental to that purpose. There is no intent to provide holders of such interests in each Trust with diverse interests in the assets of each Trust.

-34-

(G)    Since January 1, 2015, GBNK has not exercised its right to defer interest payments on the Debentures.

(H)    Each Trust’s income consists solely of payments made by GBNK with respect to the respective Debentures, and such payments are not derived from the active conduct of a financial business by such Trust. Both GBNK’s obligation to make those payments and the amounts thereof are set forth in the respective Debentures. Neither GBNK’s obligation to make those payments nor the amounts payable by GBNK is dependent on income or profits of GBNK or any Affiliate of GBNK (although GBNK’s ability to do so is so dependent).

(I)    GBNK has not issued any class of capital shares either pari passu or senior to the Debentures. All Debentures are either pari passu or senior to GBNK’s trade accounts payable arising in the ordinary course of business.

(J)    GBNK and the Trusts have created a debtor-creditor relationship between GBNK, as debtor, and each Trust, as a creditor, and GBNK and the Trusts have treated the Debentures as indebtedness for all tax purposes.

Section 3.40.    Investment Advisor Subsidiary.

(A)    Confidential Schedule 3.40 lists each GBNK Subsidiary that provides investment management, investment advisory or sub-advisory services to any Person (including management and advice provided to separate accounts and participation in wrap fee programs) and that is required to register with the SEC as an investment adviser under the Investment Advisers Act of 1940, as amended (the “Investment Advisers Act”) (each, an “Advisory Entity”). Each Advisory Entity is registered as an investment adviser under the Investment Advisers Act and has operated since January 1, 2015 and is currently operating in compliance with all Laws applicable to it or its business and has all registrations, permits, licenses, exemptions, orders and approvals required for the operation of its business or ownership of its properties and assets substantially as presently conducted, except as would not reasonably be expected, either individually or in the aggregate, to result in a Material Adverse Change in GBNK. Each “investment advisory representative” (as defined under the Investment Advisers Act) required to be registered as such with any state securities authority has been since January 1, 2015 and is so registered, except as would not reasonably be expected, either individually or in the aggregate, to result in a Material Adverse Change in GBNK. There is no action, suit, proceeding or investigation pending or, to GBNK’s Best Knowledge, threatened that would reasonably be expected to assert noncompliance with any applicable Law or lead to the revocation, amendment, failure to renew, limitation, suspension or restriction of any such registrations, permits, licenses, exemptions, orders and approvals in any material respect.

(B)    Each Advisory Entity has been since January 1, 2015 and is in all material respects in compliance with each contract for services provided in its capacity as an Advisory Entity to which it is a party.

(C)    The accounts of each advisory client of GBNK or its Subsidiaries, for purposes of the Investment Advisers Act, that are subject to ERISA have been managed by the applicable Advisory Entity in all material respects in compliance with the applicable requirements of ERISA.

-35-

(D)    Except as disclosed on a Uniform Application for Investment Adviser Registration on Form ADV (each, a “Form ADV”) neither an Advisory Entity nor to the Best Knowledge of GBNK any of their directors, officers, or employees has been the subject of any disciplinary proceedings or orders of any Governmental Authority arising under applicable Law which would be required to be disclosed on Forms ADV. None of the Advisory Entities nor any “person associated with an investment adviser” (as defined in the Investment Advisers Act) of any of them is ineligible pursuant to Section 203 of the Investment Advisers Act to serve as an investment advisor or as a Person associated with a registered investment advisor, and there is no action, suit, proceeding or investigation pending or, to GBNK’s Best Knowledge, threatened that would reasonably be expected to result in ineligibility of any such person.

(E)    GBNK has made available to IBG true and complete copies of each Form ADV filed since January 1, 2015 by each Advisory Entity, reflecting all amendments thereto to the date hereof (each, a “GBNK Form ADV”). The GBNK Forms ADV were each timely filed, were complete and accurate in all material respects at the time of filing thereof, and are in compliance in all material respects with the applicable requirements of the Investment Advisers Act. Since January 1, 2015, each Advisory Entity has made available to each advisory client its Form ADV to the extent required by the Investment Advisers Act. GBNK has made available to IBG true and complete copies of all deficiency letters and inspection reports or similar documents furnished to any Advisory Entity by the SEC since January 1, 2015 and the Advisory Entity’s responses thereto, if any.

(F)    None of GBNK or any GBNK Subsidiary serves as an investment adviser (or an investment sub-adviser) to a registered investment company.

Section 3.41.    No Broker-Dealer Subsidiary. Neither GBNK nor any Subsidiary of GBNK is a broker-dealer required to be registered under the Exchange Act with the SEC. Neither GBNK nor any Subsidiary of GBNK is subject to Section 9(a) or 9(b) of the Investment Company Act of 1940.

Section 3.42.    Broker’s Fees. Neither GBNK nor any of its Subsidiaries has any responsibility or liability for any fees, expenses or commissions payable to any agent, representative, finder, financial advisor or broker in connection with the Merger or the other transactions contemplated by this Agreement, except for Keefe, Bruyette & Woods, Inc., pursuant to an agreement, a copy of which has been provided to IBG.

Section 3.43.    No Other Representations or Warranties.

(A)    Except for the representations and warranties in this Article III, neither GBNK nor any other Person makes any express or implied representation or warranty with respect to GBNK and its Subsidiaries, or their respective businesses, operations, assets, liabilities, conditions (financial or otherwise) or prospects, and GBNK hereby disclaims any such other representations or warranties. In particular, without limiting the foregoing disclaimer, and except for the representations and warranties made by GBNK in this Article III, neither GBNK

-36-

nor any Person makes or has made any representation to IBG or any of IBG’s Affiliates or representatives with respect to any oral or written information presented to IBG or any of IBG’s Affiliates or representatives in the course of their due diligence investigation of GBNK (including any financial projections or forecasts), the negotiation of this Agreement or in the course of the transactions contemplated hereby.

(B)    GBNK acknowledges and agrees that neither IBG nor any other Person has made or is making any express or implied representation or warranty other than those contained in Article IV.

ARTICLE IV

Except (a) as disclosed in the correspondingly enumerated section or subsection of the Confidential Schedules delivered herewith (provided, that each exception set forth on any Confidential Schedule shall be deemed to qualify such other representation and warranty to the extent that the relevance of such exception to such other representation and warranty is reasonably apparent on the face of the disclosure (notwithstanding the absence of a specific cross-reference)) or (b) disclosed in any IBG SEC Reports publicly filed prior to the date hereof (but excluding any disclosures set forth in any “risk factors,” “forward-looking statements” or “market risk” sections or other statements that are similarly non-specific or cautionary, predictive or forward-looking in nature), IBG hereby makes the following representations and warranties to GBNK.

IBG and each IBG Subsidiary is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would not reasonably be expected to, individually or in the aggregate, result in a Material Adverse Change in IBG.

Section 5.06.    Allowance for Loan Losses. GBNK shall cause Guaranty Bank to maintain its Allowance for Loan and Lease Losses (the “Allowance”) at a level consistent with Guaranty Bank’s historical methodology and in compliance with GAAP.

Section 5.07.    Untrue Representations. GBNK shall promptly notify IBG in writing if GBNK becomes aware of any fact or condition that makes untrue, or shows to have been untrue, in any material respect, any material written information provided by GBNK to IBG, any confidential schedule to this Agreement or any representation or warranty made by GBNK in Article III or that results in GBNK’s failure to comply with any covenant, condition or agreement contained in this Agreement.

Section 5.08.    Litigation and Claims. GBNK shall promptly notify IBG in writing of any material litigation, or of any claim, controversy or contingent liability that individually, or taken together with other facts, events and circumstances, is reasonably expected to become the subject of material litigation, against GBNK or any GBNK Subsidiary or affecting any of their Properties. GBNK shall promptly notify IBG in writing of any legal action, suit or proceeding or judicial, administrative or governmental investigation, pending or, to the Best Knowledge of GBNK, threatened against GBNK or any GBNK Subsidiary that (i) questions or would

-59-

reasonably be expected to question the validity of this Agreement or the agreements contemplated hereby, or any actions taken or to be taken by GBNK or any GBNK Subsidiary pursuant hereto or (ii) seeks to enjoin or otherwise restrain the transactions contemplated hereby.

Section 5.09.    Adverse Changes.

Section 5.10.    No Negotiation with Others.

(A)    GBNK agrees that it shall not, and that it shall cause each GBNK Subsidiary and the respective employees, directors, officers, financial advisors, agents and other representatives of GBNK and each GBNK Subsidiary (collectively, “GBNK Representatives”) not to, directly or indirectly, (i) solicit, knowingly encourage or facilitate, initiate or participate in any negotiations or discussions with any third party (except for the limited purpose of notifying such Person of the existence of the provisions of this Section 5.10) regarding an Acquisition Proposal (as defined below), whether by acquisition, business combination, purchase of securities or assets or otherwise; (ii) disclose to any third party any information concerning the business, Properties, books or records of GBNK or any GBNK Subsidiary in connection with any Acquisition Proposal; or (iii) cooperate with any third party to make any Acquisition Proposal. Promptly upon receipt of any unsolicited offer, GBNK will communicate to IBG the terms of any proposal or request for information and the identity of the parties involved. Notwithstanding anything to the contrary contained in this Agreement, unless this Agreement has been terminated in accordance with its terms, GBNK shall not, and it shall cause each GBNK Subsidiary and GBNK Representative not to, execute or enter into any letter of intent, agreement in principle, merger agreement, asset or stock purchase or share exchange agreement, option agreement or other contract related to any Acquisition Proposal (other than a confidentiality agreement entered into in accordance with Section 5.10(B)).

(B)    Notwithstanding anything to the contrary contained in this Section 5.10, if at any time after the date hereof and before the receipt of the Requisite GBNK Stockholder Approval, GBNK and the GBNK Representatives, having each theretofore complied with the terms of Section 5.10(A), receives a bona fide, unsolicited written Acquisition Proposal, GBNK and the GBNK Representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to IBG or is made available to IBG before or concurrently with the time such information or access is made available to such person) to, any Person making such Acquisition Proposal if, and only if, the GBNK Board determines in good faith, after consultation with outside legal and financial advisors, that (i) such Acquisition Proposal constitutes or is reasonably likely to become a Superior Proposal (as defined below) and (ii) the failure of the GBNK Board to furnish such information or access or enter into such discussions or negotiations would be inconsistent with its fiduciary duties under applicable Law; but before furnishing any such information, GBNK shall have received from the Person making such Acquisition Proposal

-60-

an executed confidentiality agreement with terms at least as restrictive in all material respects on such Person as the Confidentiality Agreement entered into with IBG dated April 20, 2018 (the “Confidentiality Agreement”), which confidentiality agreement shall not prohibit GBNK from complying with the terms of this Section 5.10. GBNK will promptly, and in any event within twenty-four (24) hours, (x) notify IBG in writing of the receipt of such Acquisition Proposal or any request for information relating to GBNK or for access to the Properties, books or records of GBNK by any Person that has made, or to the Best Knowledge of GBNK may be considering making, an Acquisition Proposal and (y) communicate the material terms of such Acquisition Proposal to IBG, including as they may change upon any modification or amendment to the terms thereof, and including the identity of the Person making the Acquisition Proposal and a copy thereof if in writing and any related documentation or correspondence. GBNK will keep IBG reasonably apprised of the status of and other matters relating to any such Acquisition Proposal on a timely basis, including providing a copy of all further related documentation or correspondence.

(C)    GBNK agrees that it (i) will and will cause the GBNK Subsidiaries and GBNK Representatives to, cease immediately and terminate any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal or similar transaction and (ii) will not release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which it or any of its Subsidiaries is a party with respect to any Acquisition Proposal or similar transaction, and will enforce the terms thereof and will promptly request from such third parties the return or destruction of any confidential information of GBNK provided thereunder. Nothing contained in this Agreement shall prevent (I) GBNK or the GBNK Board from (i) taking the actions provided in Section 1.08(C) or 5.10(B) subject to compliance with the terms thereof, (ii) responding to an unsolicited bona fide Acquisition Proposal for the sole purpose of clarifying the terms and conditions of the Acquisition Proposal, or (iii) informing any Person who submits an unsolicited bona fide Acquisition Proposal of GBNK’s obligations pursuant to Section 5.10(A), or (II) either party, in consultation with outside counsel, complying with its disclosure obligations under federal or state Law including in connection with a GBNK Change in Recommendation (provided that any GBNK Change in Recommendation shall be subject to Section 1.08(C) and shall have the effects set forth in this Agreement).

(D)    For purposes of this Agreement, “Acquisition Proposal” means any offer, inquiry, indication of interest or proposal from a party other than IBG regarding any of the following (other than the transactions contemplated by this Agreement) involving GBNK or any GBNK Subsidiary: (i) any merger, reorganization, consolidation, share exchange, recapitalization, business combination, liquidation, dissolution or other similar transaction involving GBNK or any GBNK Subsidiary or any sale, lease, exchange, mortgage, pledge, transfer or other disposition of 20% or more of the consolidated assets of GBNK or any GBNK Subsidiary, in a single transaction or series of related transactions; or (ii) any acquisition by any party or group of parties (including the shareholders or equity holders thereof), directly or indirectly, including by any tender offer or exchange offer, of 20% or more of the outstanding GBNK Shares or of the total voting power of GBNK or any GBNK Subsidiary.

(E)    For purposes of this Agreement, “Superior Proposal” means an unsolicited bona fide written Acquisition Proposal made by a party other than IBG to acquire, directly or

-61-

indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination or similar transaction, all or substantially all of the consolidated assets of GBNK or all of the GBNK Shares and that the GBNK Board determines in its good faith judgment, after consultation with its outside legal and financial advisors (i) is or would result in a transaction that if consummated would be more favorable to GBNK’s stockholders from a financial point of view than the Merger, taking into account all of the terms and conditions of such proposal and of this Agreement (including any proposal by IBG to amend the terms of this Agreement) and (ii) is capable of being, and is reasonably likely to be, consummated on a timely basis on the terms so proposed taking into account all financial, regulatory, legal and other aspects of such proposal.

Section 5.11.    Non-Governmental Consents and Approvals. GBNK shall use commercially reasonable efforts to obtain all consents and approvals from third parties necessary or advisable in connection with the transactions contemplated by this Agreement. GBNK will cooperate in all commercially reasonable respects with IBG to obtain all such approvals and consents required of IBG. Without limiting the foregoing, as soon as reasonably practicable after the date hereof, GBNK shall cause each of its Subsidiaries that is an Advisory Entity to inform their investment advisory clients of the transactions contemplated by this Agreement and request each such client’s written consent to the deemed assignment of its management contract resulting from the change in ownership of GBNK and the relevant Advisory Entity resulting from the transactions contemplated by this Agreement and use all reasonable efforts to obtain such consent on or before the Effective Time. While GBNK shall request affirmative written consents from each Advisory Entity’s clients to such deemed assignment, a negative consent will constitute valid consent to the extent permitted by applicable Law and the applicable management contract if (i) a negative consent is not expressly prohibited by the management contract (for purposes of this Agreement, it is assumed that, unless an agreement expressly requires written consent to an “assignment” as defined under the Investment Advisers Act or a change in control, then such “negative consent” or “silence” is permissible hereunder and thereunder), (ii) a notice describing the change in control and the negative consent in a form reasonably acceptable to IBG and GBNK is sent to each client, and (iii) sixty (60) days elapse from the date that notice is received at the client’s office during which period the client continues to have its account managed by the applicable Advisory Entity and does not notify the applicable Advisory Entity that it is withholding its consent and such client shall not have otherwise provided a notice of termination of the relevant management contract that provides for the termination to be effective as of or prior to the Closing Date.

Section 5.12.    Termination of Employee Plans. If requested by IBG in writing delivered to GBNK by 20 Business Days before the Closing Date, the GBNK Board (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary to terminate any Employee Plan that is a tax-qualified savings plan (the “GBNK 401(k) Plans”), effective as of the day prior to the Closing Date. The form and substance of such resolutions and any other actions taken in connection with the foregoing termination shall be subject to the review and approval of IBG. Following the Effective Time and (if IBG determines in its sole discretion that a determination letter is appropriate) as soon as practicable following receipt of a favorable determination letter from the IRS on the termination of the GBNK 401(k) Plans, the assets thereof shall be distributed to the participants, and IBG shall, to the extent permitted by IBG’s 401(k) plan (the “IBG 401(k) Plan”), permit the employees of GBNK and its Subsidiaries who are actively employed as of the date immediately following the distribution of account

-62-

balances under the GBNK 401(k) Plans to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code, but excluding loans), in the form of cash, from the amounts distributed to such employee from the GBNK 401(k) Plan to the IBG 401(k) Plan.

Section 5.13.    Other Agreements. GBNK shall, and shall cause each GBNK Subsidiary to, execute and deliver the Bank Merger Agreement and such other agreements, certificates of merger, certificates, and other documents reasonably necessary to effect the Merger and the Bank Merger, and to take all actions reasonably necessary or required to consummate the transactions contemplated thereby in accordance with the terms hereof.

Section 5.14.    Support Agreement. GBNK shall use commercially reasonable efforts to cause each outside director of GBNK and Guaranty Bank to execute and deliver to IBG, contemporaneously with the execution of this Agreement, a Director Support Agreement providing for the continuing support of Independent Bank by the outside directors (the “Director Support Agreements”).

Section 5.15.    Conforming Accounting Adjustments. GBNK shall, if requested in writing by IBG, consistent with GAAP and applicable banking Laws immediately before Closing, make such accounting entries as GBNK may reasonably request in order to conform the accounting records of GBNK to the accounting policies and practices of IBG. No such adjustment by GBNK or any GBNK Subsidiary shall of itself constitute or be deemed to be a breach, violation or failure by GBNK or any GBNK Subsidiary to satisfy any representation, warranty, covenant, condition or other provision of this Agreement or constitute grounds for termination of this Agreement by IBG or be an acknowledgment by GBNK of any adverse circumstances for purposes of determining whether the conditions to IBG’s obligations under this Agreement have been satisfied. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence by GBNK, any GBNK Subsidiary or their respective management with any such adjustments.

Section 5.16.    D&O Liability Insurance. Contemporaneously with the Closing, GBNK shall purchase an extended reporting period for six (6) years under GBNK’s existing directors and officers liability insurance policy for purposes of covering actions occurring prior to the Effective Time, on terms approved by IBG. Notwithstanding any other provision of this Agreement, the aggregate cost of the premiums for such coverage shall not exceed 300% of the current annual premium for such insurance paid by GBNK as of the date of this Agreement.

Section 5.17.    Termination of DP Contracts and IT Conversion. At IBG’s request and in consultation with IBG, GBNK will use commercially reasonable efforts, including but not limited to notifying appropriate parties and negotiating in good faith a reasonable settlement, to ensure that the DP Contracts and contracts related to the provision of any other electronic banking services, if the Merger occurs, be terminated after the consummation of the Merger on a date to be mutually agreed upon by IBG and GBNK. Such notice and actions by GBNK will be in accordance with the terms of such contracts. GBNK shall use reasonable efforts and cooperate with IBG to facilitate a smooth conversion of data processing, item processing, network and related hardware and software, telephone systems, telecommunications, data communications and other technologies, including participating in conversion planning, design, mapping and testing activities before the Closing Date.

-63-

IBG shall promptly notify GBNK in writing of any legal action, suit or proceeding or judicial, administrative or governmental investigation, pending or, to the Best Knowledge of IBG, threatened against IBG or Independent Bank that (i) questions or would reasonably be expected to question the validity of this Agreement or the agreements contemplated hereby or any actions taken or to be taken by IBG with respect hereto or thereto, or (ii) seeks to enjoin or otherwise restrain the transactions contemplated hereby or thereby.

-66-

Section 6.07.    Regulatory and Other Approvals. With the reasonable cooperation of GBNK, IBG shall use commercially reasonable efforts to prepare all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of (i) all third parties and (ii) all federal or state bank regulatory authorities or Governmental Authorities necessary to consummate the Merger, the Bank Merger and the other transactions contemplated by this Agreement, including the applications for the prior approval of the Merger and the Bank Merger by the FRB (or appropriate Federal Reserve Bank acting on delegated authority), the TDB, the FDIC and the Colorado Division of Banking (collectively, the “Regulatory Approvals”). Provided that GBNK has promptly provided information reasonably requested by IBG and its comments to draft applications, and otherwise complied with Section 5.02, IBG shall file all such applications on or before the thirtieth (30th) day following the date of this Agreement. IBG shall use commercially reasonable efforts to obtain all such regulatory approvals and any other approvals from third parties at the earliest practicable time. IBG and GBNK shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable Law relating to the exchange of information, all the information relating to IBG or GBNK, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted or proposed to be submitted to, any third party or any Governmental Authority in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. In addition, IBG shall keep GBNK reasonably informed as to the status of such applications and filings; IBG shall promptly furnish GBNK and its counsel with copies of all such regulatory filings and all correspondence with respect thereto to the extent permitted by applicable Law; and to the extent permitted by applicable Law, each party shall promptly advise the other upon receiving any communication from any Governmental Authority 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 such approval will not be obtained or that the receipt of any such approval will be materially delayed. Notwithstanding anything to the contrary contained in this Agreement, IBG shall not be required to (and GBNK shall not be permitted to, without IBG’s prior written consent) take any action, or commit to take any action, or agree to any condition or restriction, involving IBG, GBNK or any of their respective Subsidiaries pursuant to this Section 6.07 or otherwise in connection with obtaining any permits, consents, approvals and authorizations that would reasonably be expected to be materially burdensome on IBG, GBNK, the Resulting Corporation or their respective Subsidiaries or require a material modification of, or impose any material limitation or restriction on, the activities, governance, legal structure, capital structure, compensation or fee arrangements of IBG, GBNK, the Resulting Corporation or any of their respective Subsidiaries (any of the foregoing, a “Burdensome Condition”); provided, however, that the following shall not be deemed to be a Burdensome Condition: any restraint, limitation, term, requirement, provision or condition that applies generally to bank holding companies and banks as provided by statute, regulation, or written and publicly available supervisory guidance of general applicability, in each case, as in effect on the date hereof.

Section 6.08.    Other Agreements. IBG shall, and shall cause Independent Bank to, execute and deliver the Bank Merger Agreement and such other agreements, certificates of merger, certificates, and other documents reasonably necessary to effect the Merger and the Bank Merger and to take all actions reasonably necessary or required to consummate the transactions contemplated thereby in accordance with the terms hereof.

-67-

Section 6.09.    Employee Matters.

(A)    To the extent that an employee of GBNK and its Subsidiaries immediately prior to the Closing (collectively, the “Covered Employees”) becomes eligible to participate in an employee benefit plan maintained by the Resulting Corporation or any of its Subsidiaries (other than GBNK or its Subsidiaries) following the Effective Time, the Resulting Corporation shall cause such employee benefit plan to recognize the service of such Covered Employee with GBNK or its Subsidiaries for purposes of eligibility, participation, vesting and benefit accrual under such employee benefit plan of the Resulting Corporation or any of its Subsidiaries, to the same extent that such service was recognized immediately prior to the Effective Time under a similar Employee Plan in which such Covered Employee was eligible to participate immediately prior to the Effective Time; provided that, such recognition of service shall not (i) operate to duplicate any benefits of a Covered Employee with respect to the same period of service, or (ii) apply for purposes of any retiree medical plans or for purposes of benefit accrual under any defined benefit pension plan. With respect to any health care, dental or vision plan of the Resulting Corporation or any of its Subsidiaries (other than GBNK and its Subsidiaries) in which any Covered Employee is eligible to participate, for the plan year in which such Covered Employee is first eligible to participate, the Resulting Corporation shall (x) cause any preexisting condition limitations or eligibility waiting periods under such Resulting Corporation or Subsidiary plan (excluding any Employee Plan) to be waived with respect to such Covered Employee to the extent that such limitation would have been waived or satisfied under the similar Employee Plan in which such Covered Employee participated immediately prior to the Effective Time, and (y) use commercially reasonable efforts to cause any health care, dental and vision expenses incurred by such Covered Employee in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) to be recognized for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such health, dental or vision plan of the Resulting Corporation or any of its Subsidiaries (excluding any Employee Plan), to the extent that any such amount was recognized for a similar purpose under the Employee Plans in which such Covered Employee participated immediately prior to the Effective Time.

(B)    From and after the date hereof, any written communications to the employees, officers or directors of GBNK or any of its Subsidiaries pertaining to compensation or benefit matters after the Closing or otherwise relating to the transactions contemplated by this Agreement, shall be in the form of mutually agreeable communications, prepared in prior consultation with IBG, it being agreed that IBG and GBNK shall cooperate, including by providing IBG a reasonable period of time to review any such communication, in providing mutually agreeable communications.

(C)    For a period beginning at the Effective Time and continuing through the first anniversary thereof, the Resulting Corporation and its Subsidiaries shall provide severance to each Covered Employee pursuant to the terms and conditions of the severance plan or policy of GBNK or its Subsidiaries applicable to such Covered Employee as of the date hereof (in each case, as set forth on Confidential Schedule 6.09(C)).

(D)    Prior to the Effective Time, GBNK may pay to each Covered Employee who at the time of the payment is then participating in any GBNK annual cash bonus plan or

-68-

annual cash incentive plan in effect for the 2018 fiscal year identified on Confidential Schedule 6.09(D) (the “Annual Bonus Plans”) a bonus under such Annual Bonus Plans for the period between January 1, 2018 and the Closing Date; provided that, the aggregate of such bonus payments must not exceed GBNK’s unpaid aggregate accrual for such bonus payments as of the Closing Date (the “Bonus Accrual Amount”). The Bonus Accrual Amount shall be based on the amount accrued by GBNK in respect of the Annual Bonus Plans in the ordinary course of business consistent with past practices and in accordance with GAAP based on GBNK’s actual performance for the period from January 1, 2018 through the latest practicable date prior to the Closing Date. The Bonus Accrual Amount shall be allocated among such Covered Employees in the ordinary course of business consistent with past practices. GBNK shall consult with IBG regarding the determination and allocation of the Bonus Accrual Amount and consider IBG’s comments on such determination and the allocation thereof in good faith. For the avoidance of doubt, (i) if bonuses are paid to employees under the Annual Bonus Plans in the ordinary course of business consistent with past practices prior to the Effective Time, this Section 6.09(D) shall have no force and effect and (ii) any bonuses paid pursuant to this Section 6.09(D) shall be paid in a manner which avoids the duplication of any benefits which may be provided under any other Employee Plan.

(E)    From and after the Effective Time, the Resulting Corporation shall, or shall cause its Subsidiaries to, (i) assume and honor the Employee Plans set forth on Confidential Schedule 3.28 in accordance with their terms; provided that, nothing herein shall prohibit the Resulting Corporation from amending, suspending or terminating any such Employee Plan to the extent permitted by the governing documents of such Employee Plan or applicable Law, and (ii) honor and discharge all GBNK’s and the GBNK Subsidiaries’ obligations and assume all of its and their defenses under existing change of control and employment agreements to which GBNK or any GBNK Subsidiary is a party that are set forth on Confidential Schedule 3.28. Without limiting the generality of Section 10.13, the provisions of this Section 6.09 are solely for the benefit of the parties to this Agreement, and no current or former employee, officer, director or independent contractor or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement. In no event shall the terms of this Agreement be deemed to (a) establish, amend or modify any Employee Plan or any other employee benefit plan, program, agreement or arrangement maintained or sponsored by the Resulting Corporation, IBG, GBNK or any of their respective affiliates; (b) alter or limit the ability of IBG or any of its Subsidiaries to amend, modify or terminate any Employee Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date; or (c) confer upon any current or former employee, officer, director or independent contractor any right to employment or continued employment or continued service with the Resulting Corporation or any of its Subsidiaries (including, following the Closing Date, GBNK and its Subsidiaries), or constitute or create an employment agreement with any employee.

Section 6.10.    Adverse Changes. IBG shall promptly notify GBNK in writing if any change shall have occurred or, to the Best Knowledge of IBG, been threatened (or any development shall have occurred or, to the Best Knowledge of IBG, been threatened involving a prospective change) in the business, financial condition, or operations of IBG and/or Independent Bank that has resulted in or may reasonably be expected to result in a Material Adverse Change with respect to IBG or Independent Bank or lead to a failure to obtain necessary regulatory approval of the transactions contemplated by this Agreement.

-69-

Section 6.11.    Issuance of IBG Common Shares. The IBG Shares to be issued by IBG to the stockholders of GBNK pursuant to this Agreement will, on the issuance and delivery to such stockholders pursuant to this Agreement, be duly authorized, validly issued, fully paid and nonassessable. The IBG Shares to be issued to the stockholders of GBNK pursuant to this Agreement are and will be free of any preemptive rights of the stockholders of GBNK or any other Person, and are not and will not be restricted securities under the Securities Act, except for IBG Shares issued by IBG to any GBNK stockholders who may be deemed to be an “affiliate” of IBG under the Securities Act after completion of the Merger.

Section 6.12.    Access to Properties and Records. To the extent permitted by applicable Law, IBG shall and shall cause each of its Subsidiaries, upon reasonable notice from GBNK to IBG to: (a) afford the employees and officers and authorized representatives (including legal counsel, accountants and consultants) of GBNK reasonable access to the properties, books and records of IBG and its Subsidiaries during regular business hours in order that GBNK may have the opportunity to make such reasonable investigation as it shall desire to make of the affairs of IBG and its Subsidiaries, and (b) furnish GBNK with such additional financial and operating data and other information as to the business and properties of IBG as GBNK may, from time to time, reasonably request; provided, however, that GBNK shall request permission for all such access reasonably in advance and all such access shall be conducted in a manner designed to minimize disruption to the normal business operations and employee or customer relations of IBG and each IBG Subsidiary. No investigation by GBNK or its representatives shall affect the representations and warranties set forth herein.

Section 6.13.    Director and Officer Indemnification. From and after the Effective Time, the Resulting Corporation shall indemnify, defend and hold harmless, to the fullest extent permitted by applicable Law, each present and former officer, director and employee of GBNK and any GBNK Subsidiary against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses damages or liabilities arising, in whole or in part, out of matters, actions or omissions occurring at or prior to the Effective Time and arising out of or pertaining to the fact that such person is or was an officer, director or employee of GBNK or any GBNK Subsidiary (including, without limitation, matters, actions or omissions related to the negotiation, execution, approval and performance of this Agreement or consummation of the Merger), including advancement of expenses as further specified below. If the Resulting Corporation or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of the Resulting Corporation or the surviving company shall assume the obligations set forth in this Section 6.13 prior to or simultaneously with the consummation of such transaction. The Resulting Corporation shall also advance expenses as incurred by any such indemnified party hereunder to the fullest extent permitted by applicable Law; provided that the indemnified party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such indemnified party is not entitled to indemnification. The Resulting Corporation shall reasonably cooperate with the indemnified party, and the indemnified party shall reasonably cooperate with the Resulting

-70-

Corporation, in the defense of any such claim, action, suit, proceeding or investigation. The obligations of the Resulting Corporation under this Section 6.13 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any party entitled to indemnification hereunder without the prior consent of such affected party. The provisions of this Section 6.13 shall survive the Effective Time and are intended for the benefit of, and shall be enforceable by, each party entitled to indemnification hereunder and his or her heirs and representatives.

Section 6.14.    Appointment of Directors. Effective immediately after the Effective Time, the IBG Board shall adopt resolutions and take such other action as necessary to appoint Edward B. Cordes and Paul W. Taylor (the “GBNK Nominees”) to the IBG Board, each for a term expiring at the next annual meeting of the shareholders of IBG following the Effective Time. IBG shall nominate, and recommend that the IBG shareholders elect, each of the GBNK Nominees to the IBG Board as a Class III director at the 2019 annual meeting of IBG shareholders. Notwithstanding the foregoing, IBG’s obligation to nominate and recommend each GBNK Nominee is subject to such GBNK Nominee’s compliance with IBG’s governance and ethics policies in place from time to time, as reasonably determined by IBG’s Corporate Governance and Nominating Committee.

Section 6.15.    Section 16 Matters. Each of the GBNK Board and the IBG Board shall, prior to the Effective Time, take all such reasonable actions as may be necessary or appropriate pursuant to Rule 16b-3 under the Exchange Act to exempt the conversion of GBNK Shares and GBNK equity awards pursuant to the terms of this Agreement by officers and directors of GBNK subject to the reporting requirements of Section 16(a) of the Exchange Act or by officers or directors of GBNK who may become an officer or director of the Resulting Corporation subject to the reporting requirements of Section 16(a) of the Exchange Act. In furtherance of the foregoing, prior to the Effective Time, (i) the GBNK Board shall adopt resolutions that specify (A) the name of each individual whose disposition of GBNK Shares (or GBNK equity awards) is to be exempted, (B) the number of GBNK Shares (and GBNK equity awards) to be disposed of by each such individual and (C) that the approval is granted for purposes of exempting the disposition from Section 16(b) of the Exchange Act under Rule 16b-3(e) of the Exchange Act and (ii) the IBG Board shall adopt resolutions that specify (A) the name of each individual whose acquisition of IBG Shares (or IBG equity awards) is to be exempted, (B) the number of IBG Shares (and IBG equity awards) to be acquired by each such individual and (C) that the approval is granted for purposes of exempting the acquisition from Section 16(b) of the Exchange Act under Rule 16b-3(d) of the Exchange Act. Each party shall provide to counsel of the other party for its review (x) copies of such resolutions to be adopted by the respective boards of directors prior to such adoption and (y) copies of such resolutions as adopted, and each party shall provide the other party with such information as shall be reasonably necessary for the other party’s board of directors to set forth the information required in the resolutions of such board of directors.

Section 6.16.    Dividends. After the date of this Agreement, IBG and GBNK shall coordinate with the other the declaration of any dividends in respect of IBG Shares and GBNK Shares and the record dates and payment dates relating thereto, it being the intention of the parties that holders of GBNK Shares shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their GBNK Shares and any IBG Shares any such holder receives in exchange therefor in the Merger.

-71-

Section 6.17.    Takeover Statutes. No party shall take any action that would cause this Agreement, the Merger or any of the other transactions contemplated by this Agreement to be subject to requirements imposed by any takeover Laws of any state, including any “moratorium,” “control share,” “fair price,” “takeover” or “interested shareholder” Law (any such Laws, “Takeover Statutes”), and each party shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated by this Agreement, or if necessary challenge the validity or applicability of, any applicable Takeover Statute, as now or hereafter in effect.

Section 6.18.    Untrue Representations. IBG shall promptly notify GBNK in writing if IBG becomes aware of any fact or condition that makes untrue, or shows to have been untrue, in any material respect, any material written information provided by IBG to GBNK, any confidential schedule to this Agreement or any representation or warranty made by IBG in Article IV or that results in IBG’s failure to comply with any covenant, condition or agreement contained in this Agreement.

Section 6.19.    Transaction Litigation. IBG shall give GBNK prompt notice of any litigation against IBG and/or its directors relating to the Merger and the other transactions contemplated by this Agreement and shall give GBNK the opportunity to participate, at GBNK’s cost, in the defense or settlement of any such litigation, and no such settlement shall be agreed to without the prior written consent of GBNK, which consent shall not be unreasonably withheld, conditioned or delayed. For purposes of this paragraph, “participate” means that the non-litigating party will be kept apprised of proposed strategy and other significant decisions with respect to the litigation by the litigating party, consistent with the common interest of IBG and GBNK in these matters and the applicable privileges and protections provided therein, and the non-litigating party may offer comments or suggestions with respect to the litigation and any documents to be prepared or filed in connection therewith, which will be reasonably considered in good faith by the litigating party.

(A)    By the mutual written consent of GBNK and IBG, duly authorized by the GBNK Board and the IBG Board, respectively.

-75-

(B)    By either GBNK or IBG if the Closing shall not have occurred on or before April 2, 2019 (the “Closing Date Deadline”); provided, however, that the right to terminate this Agreement under this Section 9.01(B) shall not be available to any party whose action or failure to act has been the cause of or resulted in the failure of the Closing to occur on or before such date and such action or failure to act constitutes a material breach of this Agreement.

(C)    By either IBG or GBNK if (i) any Regulatory Approval required to be obtained pursuant to Section 8.04 or Section 7.03 has been denied by the relevant Governmental Authority and such denial has become final and nonappealable or if any such Regulatory Approval includes, or will not be issued without, the imposition of a Burdensome Condition, or (ii) any Governmental Authority of competent jurisdiction shall have issued an order, injunction, decree or ruling or taken any other action permanently restraining, enjoining, invalidating or otherwise prohibiting this Agreement or any other agreement contemplated hereby, or the transactions contemplated hereby or thereby and such order, injunction, decree, ruling or other action shall have been final and nonappealable.

(D)    By IBG, if GBNK shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement which breach or failure, if continuing on the Closing Date, would, individually or together with all other such uncured breaches or failures by GBNK, constitute grounds for the conditions set forth in Section 8.01 or Section 8.02 not to be satisfied on the Closing Date, and such breach or failure shall not have been cured within a period of thirty (30) calendar days after written notice from IBG (or such fewer days as remain prior to the Closing Date Deadline).

(E)    By GBNK, if IBG shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure, if continuing on the Closing Date, would, individually or together with all other such uncured breaches or failures by IBG, constitute grounds for the conditions set forth in Section 7.01 or Section 7.02 not to be satisfied on the Closing Date, and such breach or failure shall not have been cured within a period of thirty (30) calendar days after written notice from GBNK (or such fewer days as remain prior to the Closing Date Deadline).

-76-

(H)    By GBNK, if IBG or the IBG Board shall have failed to comply in any material respect with its obligations under Section 1.08(D).

(1)    The number obtained by dividing the Average Closing Price by the Starting Price (each as defined below) (the “IBG Ratio”) shall be less than 0.85; and

(2)    (x) the IBG Ratio shall be less than (y) the number obtained by dividing the Final Index Price by the Index Price on the Starting Date (each as defined below) and subtracting 0.15 from the quotient in this clause (2)(y);

subject, however, to the following three sentences. If GBNK elects to exercise its termination right pursuant to this Section 9.01(I), it shall give written notice to IBG. Following its receipt of such notice, IBG shall have the option, at its sole discretion, to increase the consideration to be received by the GBNK stockholders hereunder, by adjusting the Exchange Ratio (calculated to the nearest ten-thousandth) to a number (rounded to the nearest ten-thousandth) equal to the quotient of (A) the product of (i) the product of the Starting Price, multiplied by 0.85, multiplied by (ii) the Exchange Ratio, divided by (B) the Average Closing Price. If IBG so elects, it shall give prompt written notice to GBNK of such election and the revised Exchange Ratio, whereupon no termination shall have occurred pursuant to this Section 9.01(I) and this Agreement shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified).

For purposes of this Section 9.01(I), the following terms shall have the meanings indicated:

Section 9.03.    Effect of Termination. In the event of the termination of this Agreement and abandonment of the Merger pursuant to the provisions of Section 9.01, no party to this

-77-

Agreement shall have any further liability or obligation in respect of this Agreement, except that (A) the provisions of Sections 9.03, 9.04, 10.02, 10.07, 10.11, and 10.14 and the Confidentiality Agreement shall survive any such termination of the Agreement and abandonment of the Merger and (B) notwithstanding anything to the contrary, neither IBG nor GBNK shall be relieved or released from any liabilities or damages arising out of its fraud or willful breach of any provision of this Agreement.

Section 9.04.    Termination Fee.

(A)    In the event that (i) after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been made known to senior management or the board of directors of GBNK or has been made directly to its stockholders generally, or any Person shall have publicly announced an Acquisition Proposal, (ii) thereafter this Agreement is terminated (A) by GBNK or IBG pursuant to Section 9.01(B) (if the Requisite GBNK Stockholder Approval has not theretofore been obtained but all other conditions set forth in Article VII had been satisfied or were capable of being satisfied prior to such termination), (B) by IBG pursuant to Section 9.01(D) as a result of a willful breach, or (C) by GBNK or IBG pursuant to Section 9.01(F)(i), and (iii) prior to the date that is twelve (12) months after the date of such termination, GBNK consummates a transaction included within the definition of Acquisition Proposal or enters into a definitive agreement with respect to an Acquisition Proposal, in each case, whether or not relating to the same Acquisition Proposal as that referenced in clause (i), then GBNK shall on the earlier of (x) the date such a transaction is consummated or (y) the date any such definitive agreement is entered into, as applicable, pay IBG a fee equal to $40,000,000 (the “Termination Fee”) by wire transfer of immediately available funds; provided, that, for purposes of this Section 9.04(A), all references in the definition of Acquisition Proposal to “20%” shall instead refer to “50%”.

(C)    In the event this Agreement is terminated by GBNK pursuant to Section 9.01(H), then IBG shall, within two Business Days after the date of termination, pay GBNK the Termination Fee by wire transfer of immediately available funds.

(D)    Each of GBNK and IBG acknowledges that the agreements contained in this Section 9.04 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, IBG and GBNK, respectively, would not enter into this Agreement; accordingly, if GBNK or IBG, as applicable, fails promptly to pay the amount due pursuant to this Section 9.04, and, in order to obtain such payment, IBG or GBNK (as applicable) commences a suit which results in a judgment against GBNK or IBG (as applicable) for the fee set forth herein or any portion thereof, GBNK or IBG, as applicable, shall pay to the other party its fees and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit. In addition, if IBG or GBNK fails to pay the amounts payable pursuant to this Section 9.04, then IBG or GBNK, as applicable, shall pay 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

-78-

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 200 basis points for the period commencing as of the date that such overdue amount was originally required to be paid. The amounts payable by GBNK or IBG pursuant to this Section 9.04 constitute liquidated damages and not a penalty, and, except in the case of fraud, or willful breach of this Agreement, shall be the sole monetary remedy of IBG or GBNK, as applicable, in the event of a termination of this Agreement specified in such section. In no event shall any party be required to pay the Termination Fee more than once. Each party’s obligation to pay the Termination Fee shall survive termination of this Agreement.

Upon completion of the merger, Guaranty Bank and Trust Company will be merged with and into Independent Bank.

Guaranty Bancorp, through Guaranty Bank and Trust Company, operates from its main office in Denver with 32 branches strategically located along the Colorado Front Range, including 14 locations in the Denver metropolitan area. As of March 31, 2018, Guaranty Bancorp, on a consolidated basis, reported total assets of $3.7 billion, total deposits of $3.0 billion, and total tangible common equity of $324.8 million.

Independent Bank Group Chairman and Chief Executive Officer David R. Brooks stated “We are thrilled to announce the acquisition of Guaranty Bancorp. This transaction represents the build out of our Colorado footprint through the acquisition of a high quality bank operating in dynamic markets along the Front Range.” Brooks continued, “Guaranty is the premier Colorado banking franchise and brings a committed management team, consistent level of high profitability, clean balance sheet, strong core deposit base, and a track record of growth. We are delighted to welcome Guaranty’s clients, shareholders, and employees to Independent Bank Group.”

“We are pleased to partner with an organization that shares our approach to community banking,” said Guaranty Bancorp President and Chief Executive Officer Paul W.
