AGREEMENT AND PLAN OF REORGANIZATION

This AGREEMENT AND PLAN OF REORGANIZATION (this “Agreement”) is effective as of August 29, 2025, by and among Equity Bancshares, Inc. (“EQBK”), a Kansas corporation and registered financial holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”), Winston Merger Sub, Inc. (“Merger Sub”), a Nebraska corporation and wholly-owned subsidiary of EQBK, and Frontier Holdings, LLC. (“Frontier”), a Nebraska limited liability company and registered financial holding company under the BHCA.

RECITALS

WHEREAS, EQBK owns all of the common stock of Equity Bank, a Kansas state bank with its principal office in Andover, Kansas (“Equity Bank”);

WHEREAS, Frontier owns all of the common stock of Frontier Bank, a Nebraska state bank with its principal office in Omaha, Nebraska (the “Bank”);

WHEREAS, the Board of Directors of EQBK (the “EQBK Board”) and the Board of Directors of Frontier (the “Frontier Board”) have determined that it is advisable and in the best interests of their respective companies, the shareholders of EQBK, and unitholders of Frontier to consummate the strategic business combination transaction provided for in this Agreement;

WHEREAS, on the terms and subject to the conditions set forth in this Agreement, EQBK will acquire Frontier through the merger of Merger Sub with and into Frontier (the “Merger”), with Frontier surviving as a wholly owned subsidiary of EQBK;

WHEREAS, immediately following, and in connection with, the Merger, EQBK will cause Frontier to be merged with and into EQBK, with EQBK surviving the merger (the “Second Step Merger” and together with the Merger, the “Integrated Mergers”), and immediately following the Second Step Merger, or at such later time as EQBK may determine, EQBK will cause the Bank to be merged with and into Equity Bank, with Equity Bank surviving the merger (the “Bank Merger”);

WHEREAS, concurrently with the execution and delivery of this Agreement, as a condition and inducement for EQBK to enter into this Agreement, certain members of Frontier have each entered into a Voting Agreement in the form attached hereto as Exhibit A (the “Voting Agreement”), whereby such members of Frontier have agreed to vote their Frontier Units (as defined herein) owned by them in favor of this Agreement, the Merger and the transactions contemplated hereby and thereby;

WHEREAS, concurrently with the execution and delivery of this Agreement, as a condition and inducement for EQBK to enter into this Agreement, certain of the members of Frontier have entered into Support Agreements in the form attached hereto as Exhibit B (the “Support Agreement”) in connection with the Merger;

WHEREAS, it is intended that the Integrated Mergers together be treated as a single integrated transaction as described in Rev. Rul. 2001-46, 2001-2 C.B. 321, that qualifies as a “reorganization” under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury Regulations promulgated thereunder, and this Agreement is a “plan of reorganization” within the meaning of Treasury Regulations §§1.368-2(g) and 1.368-3(a) for purposes of Sections 354, 356 and 361 of the Code (and any comparable provision of state Law); and

WHEREAS, the parties hereto desire to set forth certain representations, warranties and covenants made by each to the other as an inducement to the execution and delivery of this Agreement and certain additional agreements related to the transactions contemplated hereby:

AGREEMENT

NOW, THEREFORE, for and in consideration of the foregoing and of the mutual representations, warranties, covenants and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and subject to the conditions set forth below, the parties, intending to be legally bound, undertake, promise, covenant and agree with each other as follows:

ARTICLE I

THE MERGER

Section 1.01 Merger of Merger Sub with and into Frontier. Subject to the terms and conditions of this Agreement, at the Effective Time, Merger Sub will merge with and into Frontier in accordance with Section 21-171 of the Nebraska Uniform Limited Liability Company Act (the “RULLCA”) and Section 21-2,162 of the Nebraska Model Business Corporation Act (the “MBCA”). Frontier will be the surviving entity in the Merger (the “Surviving Entity”) and will continue its corporate existence under the MBCA. Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

Section 1.02 Effects of the Merger. The Merger will have the effects set forth in the RULLCA and the MBCA. The name of the Surviving Entity will be “Frontier Holdings, LLC.”

Section 1.03 Certificate of Organization and Operating Agreement. At the Effective Time, the articles of organization and operating agreement of Frontier (the “Frontier Operating Agreement”), as in effect immediately before the Effective Time, will be the certificate of organization and operating agreement of the Surviving Entity until thereafter changed or amended as provided by Law.

Section 1.04 Directors and Officers; Manager. The directors and officers, respectively, of Merger Sub at the Effective Time will become the directors and officers of the Surviving Entity and will hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the certificate of organization and operating agreement of the Surviving Entity or as otherwise provided by Law. At the Effective Time, the Surviving Entity shall appoint EQBK to act as its manager.

Section 1.05 Effect on Capital Stock/Units. At the Effective Time, by virtue of the Merger and without any further action on the part of EQBK, Merger Sub, Frontier or any holder of record of the following securities/interests:

2

(a) Each share of Class A common stock, par value $0.01 per share, of EQBK (“EQBK Class A Stock”) and Class B common stock, par value $0.01 per share of EQBK (“EQBK Class B Stock” and together with the EQBK Class A Stock, the “EQBK Stock”) issued and outstanding immediately prior to the Effective Time, shall remain issued and outstanding and shall not be affected by the Merger.

(b) Each unit of Frontier (each a “Frontier Unit” and collectively the “Frontier Units”) issued and outstanding immediately prior to the Effective Time, except for the Cancelled Units, shall cease to be outstanding and shall automatically be converted into and become the right to receive, without interest, the following:

(i) a number of shares of EQBK Class A Stock equal to the Exchange Ratio; and

(ii) the Per Unit Cash Amount (the aggregate consideration described in clauses (i) and (ii), such per unit amount, the “Per Unit Merger Consideration,” and in the aggregate for all holders of Frontier Units entitled to receive the Per Unit Merger Consideration under the terms of this Agreement, the “Merger Consideration”).

(c) At the Effective Time, each Frontier Unit converted into the right to receive the Per Unit Merger Consideration pursuant to this Section 1.05 shall no longer be outstanding and shall automatically be cancelled and cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such Frontier Units shall thereafter cease to have any rights with respect to such Frontier Units, except the right to receive the Per Unit Merger Consideration for such units.

(d) Any Frontier Units that are owned immediately prior to the Effective Time by Frontier, EQBK or their respective Subsidiaries (other than (i) Frontier Units held, directly or indirectly, in trust accounts, managed accounts and the like or otherwise held in a fiduciary capacity that are beneficially owned by third parties and (ii) Frontier Units held in respect of a debt previously contracted) shall be canceled and extinguished without any conversion thereof or consideration therefor (the “Cancelled Units”).

(e) No certificates representing a fractional share of EQBK Class A Stock shall be issued by EQBK. In lieu of any fractional share, each holder of Frontier Units entitled to a fractional share, upon surrender of such Frontier Units, shall be entitled to receive from EQBK an amount in cash (without interest), payable in accordance with Section 1.07, rounded to the nearest cent, determined by multiplying the fractional share by the closing price of EQBK Class A Stock as of the Calculation Date.

(f) Notwithstanding anything to the contrary herein, if, between the date hereof and the Effective Time, the outstanding shares of EQBK Class A Stock or EQBK Class B Stock increase, decrease, change into or are exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization (a “Share Adjustment”), then the Exchange Ratio shall be appropriately and proportionately adjusted so that each holder of Frontier Units shall be entitled to receive the Merger Consideration in such proportion as it would have received if the record date for such Share Adjustment had been immediately after the Effective Time.

3

(g) Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted automatically into and become one newly issued, fully paid and non-assessable unit of the Surviving Entity.

Section 1.06 Calculation of Consideration. For purposes of this Agreement, the following terms shall have the meanings set forth below:

(a) “Adjusted Cash Amount” means an amount equal to the difference between (i) $32,500,000, minus (ii) the Equity Adjustment.

(b) “Adjusted Equity” means the Frontier Equity as adjusted to reflect the payment of or accrual for all Frontier Merger Costs.

(c) “Calculation Date” means the last day of the month immediately preceding the month during which the Closing Date occurs, or such other date as mutually agreeable to the parties hereto.

(d) “Equity Adjustment” means the (i) Minimum Equity, minus (ii) Adjusted Equity; provided, that if the amount of the Adjusted Equity is greater than the Minimum Equity, then the Equity Adjustment shall be zero.

(e) “Exchange Ratio” means the amount of shares of EQBK Class A Stock equal to the quotient of 2,220,000 divided by the number of Frontier Units outstanding immediately prior to the Effective Time, except for the Cancelled Units.

(f) “Frontier Equity” means the members’ equity of Frontier, calculated as of the Calculation Date and in accordance with generally accepted accounting principles in the United States (“GAAP”) consistently applied.

(g) “Frontier Merger Costs” means the following items that have not otherwise been paid or accrued on or prior to the Calculation Date: (i) the cost of terminating any employment related agreements and obligations (including any non-competition agreements, option agreements or equity based plans); (ii) the transaction costs, fees and expenses (including, without limitation, all legal, accounting, and financial advisory fees and expenses, including any cost to obtain any opinion as to the financial fairness of the Merger) incurred by Frontier; (iii) the payments owed by Frontier to those employees and in such amounts listed on Frontier Confidential Schedule 1.06(g), including, without limitation any severance, stay-pay or retention bonus amounts or change in control payments not being paid by EQBK (all of which shall be reflected on Frontier Confidential Schedule 1.06(g) including the name of the recipient, the amount of such payment and with respect to any stay-pay or retention bonus arrangements, the date through which the recipient must remain employed by the Surviving Entity to receive the stay-pay or retention bonus amount); (iv) a mutually agreeable estimate of the cost of obtaining a determination

4

letter from the IRS in connection with the termination of a Retirement Plan; (v) any federal or state income Tax obligations (including pass-through entity and non-resident withholding Tax obligations), franchise Tax obligations or property Tax obligations imposed with respect to any tax year or period (or portion thereof) ending immediately prior to the Effective Time; (vi) the accrual or payment of all of the costs, fees, expenses, contract payments and penalties or liquidated damages necessary to be paid by Frontier in connection with any contract termination required pursuant to this Agreement, including, without limitation, all costs, fees, deconversion fees, expenses, contract payments and penalties or liquidated damages associated with the termination of the data processing, technology and other contracts contemplated by Section 5.15 hereof; (vii) any unrealized gains or any unrealized losses (as the case may be) in Frontier’s held-to-maturity securities portfolio as of the Calculation Date; (viii) a mutually agreeable estimate of the cost of preparing any required federal and state income Tax Returns of Frontier for the tax year ended September 30, 2025 and for the period from October 1, 2025 through the Closing Date; (ix) any distributions on the Frontier Units declared or to be declared through the date immediately preceding the Closing Date; (x) any amount required to be added to Frontier’s allowance for loan losses to comply with Section 5.04(k); (xi) the cost of the Audit; and (xii) any other amounts mutually agreed upon in writing by EQBK and Frontier. For the avoidance of doubt, Frontier shall pay or fully accrue all Frontier Merger Costs as of the Calculation Date, including mutually agreeable estimates of all Frontier Merger Costs to be paid after the Calculation Date.

(h) “Minimum Equity” means $99,416,508.00.

(i) “Per Unit Cash Amount” means the amount equal to the quotient of the Adjusted Cash Amount, divided by the number of the Frontier Units outstanding immediately prior to the Effective Time, except for the Cancelled Units.

Section 1.07 Exchange Procedures.

(a) Prior to the Effective Time, EQBK shall appoint an exchange agent (the “Exchange Agent”) to act as the exchange agent hereunder, which may be Equity Bank.

(b) At or prior to the Effective Time, EQBK shall deposit with or make available to the Exchange Agent, for the benefit of the holders of Certificates (as defined below), for exchange in accordance with this Section 1.07(a), (i) certificates or, at EQBK’s option, evidence of shares in book entry form, representing the shares of EQBK Class A Stock, to be issued pursuant to Section 1.05(b), and (ii) cash in an amount sufficient to pay (A) the aggregate Per Unit Merger Consideration and (B) cash in lieu of any fractional shares (such shares of EQBK Class A Stock and cash described in the foregoing clauses (i) and (ii), the “Exchange Fund”).

(c) As promptly as practicable after the Effective Time, but no later than ten (10) Business Days after the Effective Time, and subject to the receipt by the Exchange Agent of a list of Frontier’s unitholders in a format that is reasonably acceptable to the Exchange Agent, EQBK shall cause the Exchange Agent to mail to each holder of record immediately prior to the Effective Time of certificates (other than with respect to Cancelled

5

Units) representing Frontier Units (each, a “Certificate”, it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of Frontier Units), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu of such Certificate and, if reasonably required by EQBK or the Exchange Agent, the posting by such holder of Frontier Units of a bond in such amount as EQBK or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate)) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the agreement with the Exchange Agent (the “Letter of Transmittal”) and (ii) instructions for use in surrendering each Certificate in exchange for the Per Unit Merger Consideration, any cash in lieu of a fractional share of EQBK Class A Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to this Section 1.07. The Frontier unitholders will be entitled to receive their Per Unit Merger Consideration only after receipt by the Exchange Agent of a properly completed Letter of Transmittal. If a Letter of Transmittal contains an error, is incomplete or is not accompanied by all appropriate Certificates, then EQBK will cause the Exchange Agent to notify that Frontier unitholder promptly of the need for further information or documentation.

(d) As promptly as practicable after the Effective Time, but within five (5) Business Days after the surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, the Exchange Agent shall deliver to such holder of Frontier Units the Per Unit Merger Consideration and any cash in lieu of a fractional share of EQBK Class A Stock to be issued or paid with respect to each Frontier Unit represented by the Certificate, and each Certificate surrendered will be canceled. EQBK may, at its option, deliver any shares of EQBK Class A Stock in book-entry form. Until so surrendered, each Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Per Unit Merger Consideration and any cash in lieu of a fractional share of EQBK Class A Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with this Section 1.07, and any dividends or distributions to which such holder is entitled pursuant to this Section 1.07.

(e) No dividends or other distributions with respect to EQBK Class A Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of EQBK Class A Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Section 1.07. Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Certificate in accordance with this Section 1.07, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of EQBK Class A Stock represented by such Certificate and not paid and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of EQBK Class A Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the EQBK Class A Stock issuable with respect to such Certificate.

6

(f) In the event of a transfer of ownership of a Certificate representing Frontier Units prior to the Effective Time that is not registered in the unit transfer records of Frontier, the Per Unit Merger Consideration and any cash in lieu of a fractional share of EQBK Class A Stock to be issued or paid in consideration therefor shall be issued or paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such Frontier Units shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a person other than the registered holder of the Certificate or establish to the satisfaction of EQBK and the Exchange Agent that the Tax has been paid or is not applicable.

(g) EQBK, the Surviving Entity, Equity Bank, the Bank and the Exchange Agent, as the case may be, shall be entitled to deduct and withhold, if necessary, from any Per Unit Merger Consideration and any other amounts otherwise payable pursuant to this Agreement to any Person such amounts as they are required to deduct and withhold under the Code, or any provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so deducted or withheld, such amounts shall be (i) remitted to the appropriate Governmental Entity, and (ii) treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by EQBK or the Exchange Agent, as the case may be.

(h) Any portion of the Exchange Fund that remains unclaimed by the unitholders of Frontier at the expiration of six (6) months after the Effective Time shall be paid to EQBK. In such event, any former unitholders of Frontier who have not theretofore complied with this Section 1.07 shall thereafter look only to EQBK with respect to the Per Unit Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the EQBK Class A Stock deliverable in respect of each share represented by a Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

(i) Any other provision of this Agreement notwithstanding, none of EQBK, the Surviving Entity or the Exchange Agent shall be liable to a holder of Frontier Units for any amounts paid or property delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 1.08 Tax Treatment. For U.S. federal income Tax purposes, it is intended that the Integrated Mergers together be treated as a single integrated transaction as described in Rev. Rul. 2001-46, 2001-2 C.B. 321, that qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute, and is hereby adopted as, a “plan of reorganization” within the meaning of Treasury Regulation Section 1.368-2(g). From and after the date of this Agreement and until the Closing Date, each party hereto shall (and shall cause its Affiliates to) use its commercially reasonable efforts to cause the Integrated Mergers to so qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action not to be taken, which action or failure to act would reasonably be expected to prevent the Integrated Mergers from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

(a) Set forth on Frontier Confidential Schedule 3.28(a) is a complete and correct list of all “employee benefit plans” (as defined in the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), all multiple employer plans and “multiemployer plans” (as defined in the Code or ERISA), all specified fringe benefit plans as defined in Code § 6039D, and all other bonus, incentive, compensation, deferred compensation, profit sharing, stock option, stock appreciation right, stock bonus, stock purchase, employee stock ownership, savings, severance, supplemental unemployment, layoff, salary continuation, retirement, pension, health, life insurance, disability, group insurance, vacation, holiday, sick leave, fringe benefit or welfare plan or any other similar plan, agreement, policy or understanding (written or oral, qualified or nonqualified, currently effective or terminated), and any trust, escrow or other agreement related thereto, which (i) are sponsored, maintained, or contributed to, by Frontier and any of its Subsidiaries, or with respect to which Frontier and any of its Subsidiaries has or could reasonably be expected to have any liability thereunder, and (ii) provide benefits, or describe policies or procedures applicable to, or for the welfare of, any current of former officer, director, independent contractor, employee, or service provider of Frontier or any of its Subsidiaries, or the dependents or spouses of any such person, regardless of whether funded (the “Employee Plans”). Frontier has furnished or made available to EQBK, with respect to each Employee Plan, complete and correct copies of the following: (i) the three (3) most recently filed annual reports with respect to each Employee Plan (including all schedules and attachments), to the extent required to be filed under ERISA or the Code; (ii) the most recent summary plan description, together with each summary of material modification required under ERISA with respect to such Employee Plan; (iii) the most recent plan document, or, with respect to any Employee Plan not reduced to writing, a summary of material terms; (iv) all current trust agreements, insurance contracts and similar instruments with respect to each funded or insured Employee Plan; (v) any coverage, nondiscrimination and top-heavy testing reports for the last three (3) plan years with respect to each Employee Plan that is subject to coverage, nondiscrimination and/or top-heavy testing; (vi) the most recent determination or opinion letter from the IRS; (vii) all material correspondence with any Governmental Entity relating to any Employee Plan within the last three (3) years; and (viii) current investment management agreements, administrative services contracts or similar contracts relating to the ongoing administration, investment or implementation of any Employee Plan.

(b) Except as set forth on Frontier Confidential Schedule 3.28(b) no Employee Plan is a defined benefit plan within the meaning of ERISA §3(35) or is otherwise subject to ERISA Title IV, and neither Frontier nor any of its Subsidiaries has ever sponsored or otherwise maintained such a plan.

(c) Except as set forth on Frontier Confidential Schedule 3.28(c), there have been no prohibited transactions (as defined in Code §4975(c)(1)), breaches of fiduciary duty or any other breaches or violations of any Law applicable to the Employee Plans that would directly or indirectly subject Frontier, any of its Subsidiaries or any Employee Plan to any taxes, penalties, or other liabilities (including any liability arising from any indemnification agreement or policy), except to the extent that Frontier, any of its Subsidiaries or any Employee Plan sponsored by Frontier or any of its Subsidiaries is involved in such transaction or breach. Each Employee Plan that is intended to be qualified under Code §401(a) can rely on an applicable favorable determination or opinion letter, as applicable, that such plan is qualified and that the plan and the trust related thereto are exempt from federal income Taxes under Code §§ 401(a) and 501(a), respectively, and nothing has occurred to Frontier’s Knowledge that would reasonably be likely to result in

31

the revocation of such a favorable opinion letter. Each such Employee Plan is so qualified and has been operated in material compliance with applicable Law and its terms, any related trust is exempt from federal income tax under Code §501(a) and no event has occurred that will or reasonably could result in the loss of such tax exemption or to liability for any tax under Code §511. There are no pending claims, lawsuits or actions relating to any Employee Plan (other than ordinary course claims for benefits) and, to Frontier’s Knowledge, none are threatened, except to the extent that Frontier, any of its Subsidiaries, or any Employee Plan sponsored by Frontier or any of its Subsidiaries is involved in such transaction. Neither Frontier nor any of its Subsidiaries provides benefits to any employee or dependent of such employee of Frontier or any of its Subsidiaries after the employee terminates employment other than as disclosed in this Agreement or any schedule hereto or as required by Law. No written or oral representations have been made by or on behalf of Frontier or any of its Subsidiaries to any employee or former employee of Frontier or any of its Subsidiaries promising or guaranteeing any employer payment or funding for the continuation of medical, dental, life or disability coverage or any other welfare benefit (as defined in ERISA §3(1)) for any period of time beyond the end of the current plan year (except to the extent of coverage required under Code §4980B). Compliance with FAS 106 would not create any material change to the Frontier Financial Statements or the Call Reports. Except as set forth in Frontier Confidential Schedule 3.28(c), the completion of the transactions contemplated by this Agreement will not cause a termination or partial termination, or otherwise accelerate the time of payment, exercise, or vesting, or increase the amount of compensation due to any current or former employee, officer or director of Frontier or any of its Subsidiaries except (i) as required by the terms of any Employee Plan provided to EQBK or by applicable Law in connection with a qualified plan, or (ii) as contemplated by this Agreement. There are no surrender charges, penalties, or other costs or fees that would be imposed by any person against Frontier or any of its Subsidiaries, an Employee Plan, or any other person, including an Employee Plan participant or beneficiary, as a result of the hypothetical liquidation as of the Closing Date of any insurance, annuity, or investment contracts or any other similar investment held by any Employee Plan.

(d) The execution, delivery and performance by Frontier of its obligations under the transactions contemplated by this Agreement and/or the approval of Frontier’s unitholders of the Merger (whether alone or in connection with any subsequent event(s)), will not result in any payments or benefits which would not be deductible pursuant to Code §280G.

(e) Except as set forth on Frontier Confidential Schedule 3.28(e), all contributions to any Employee Plan (including, without limitation, all employer contributions, employee salary reduction contributions and all premiums or other payments (other than claims)) that are due and payable by Frontier any of its Subsidiaries on or before the Closing Date have been timely paid to or made with respect to each Employee Plan and, to the extent not presently payable, appropriate reserves have been established for the payment and properly accrued in accordance with GAAP.

32

(f) No participant, beneficiary or non-participating employee has been denied any benefit due or to become due under any Employee Plan. Neither Frontier nor any of its Subsidiaries has misled any person as to his or her rights under any Employee Plan. All obligations required to be performed by Frontier and any of its Subsidiaries under any Employee Plan have been performed in all material respects and neither Frontier nor any of its Subsidiaries is in default under or in violation of any provision of any Employee Plan. No event has occurred that would constitute grounds for an enforcement action by any party against Frontier, any of its Subsidiaries or any fiduciary of any Employee Plan under part 5 of Title I of ERISA under any Employee Plan.

(g) With respect to each “employee benefit plan” (as defined in ERISA) maintained or contributed to or required to be contributed to, currently or within the last six years, by any corporation or trade or business, the employees of which, together with the employees of Frontier and each of its Subsidiaries, are required to be treated as employed by a single employer under any of the rules contained in ERISA or Code §414 (the “Controlled Group Plans”):

(i) All Controlled Group Plans that are “group health plans” (as defined in Code §5000(b)(1) and ERISA §733(a)) have been operated up to the Closing in a manner so as to not subject Frontier or any of its Subsidiaries to any liability under Code §4980B or §4980D;

(ii) Except as set forth on Frontier Confidential Schedule 3.28(f), there is no Controlled Group Plan that is a “multiple employer plan” or “multiemployer plan” (as either such term is defined in ERISA), nor has there been any such plan under which Frontier or any of its Subsidiaries had any liability in the last 5 years (or would have had liability if notice had been given); and

Each such Controlled Group Plan is included in the listing of Employee Plans on Frontier Confidential Schedule 3.28(a).

(h) Except as set forth on Frontier Confidential Schedule 3.28(h), each Employee Plan that provides (or has provided within the past 5 years) for health, dental, vision, life, disability or similar coverage is covered by one or more third-party insurance policies and neither Frontier nor any of its Subsidiaries is liable for self-insuring any such claims.

(i) Except as set forth on Frontier Confidential Schedule 3.28(i), all Employee Plan documents, annual reports or returns, audited, compiled or unaudited financial statements, actuarial valuations, summary annual reports, and summary plan descriptions issued with respect to the Employee Plans are correct, complete, and current in all material respects, have been timely filed or distributed to the extent required by Law.

(j) Except as set forth on Frontier Confidential Schedule 3.28(j), no Employee Plan holds any stock or other securities of Frontier or any of its Subsidiaries or provides the opportunity for the grant, purchase or contribution of any such security.

33

(k) Except as provided in Frontier Confidential Schedule 3.28(k), Frontier or any of its Subsidiaries may, at any time amend or terminate any Employee Plan that it sponsors or maintains and may withdraw from any Employee Plan to which it contributes (but does not sponsor or maintain), without obtaining the consent of any third party, other than an insurance company in the case of any benefit underwritten by an insurance company, and without incurring liability except for unpaid premiums or contributions due for the pay period that includes the effective date of such amendment, withdrawal or termination and for customary termination expenses.

(l) Each Employee Plan that is a “nonqualified deferred compensation plan” within the meaning of Code §409A(d)(1) (a “Nonqualified Deferred Compensation Plan”) subject to Code §409A has (i) been maintained and operated since January 1, 2010 (or, if later, from its inception) in good faith compliance with Code §409A and all applicable IRS regulations promulgated thereunder, and (ii) since January 1, 2011, been materially in documentary and operational compliance with Code §409A and all applicable IRS guidance promulgated thereunder. No additional tax under Code §409A(a)(1)(B) has been or is reasonably expected to be incurred by a participant in any such Employee Plan. Neither Frontier nor any of its Subsidiaries is a party to, or otherwise obligated under, any contract, agreement, plan or arrangement that provides for the gross-up of taxes imposed by Code §409A(a)(1)(B). No currently outstanding stock option or other right to acquire Frontier Units or other equity security of Frontier or any of its any of its Subsidiaries under any Employee Plan, or the payment of cash based on the value thereof, (A) has, as to any employee of Frontier or any of its Subsidiaries, an exercise price that was less than the fair market value of the underlying equity security as of the date such stock option or right was granted, as determined by Frontier in good faith and in compliance with the relevant IRS guidance in effect on the date of grant (including, IRS Notice 2005-1 and § 1.409A-1 (b)(5)(iv) of the Treasury regulations), (B) has any feature for the deferral of compensation other than the deferral of recognition of income until the later of exercise or disposition of such option or right, or (C) has been granted after December 31, 2004, with respect to any class of stock of Frontier or any of its Subsidiaries that is not “service recipient stock” (within the meaning of applicable regulations under Code §409A).

Section 3.29 Obligations to Employees. All accrued obligations and liabilities of Frontier, each of its Subsidiaries and all Employee Plans, for payments to trusts (including grantor trusts) or other funds, to any government agency or authority, or to any present or former director, officer, employee or agent (or his or her heirs, legatees or legal representatives) with respect to any of the matters listed below have been timely paid to the extent required by applicable Law or the terms of such plan, contract program, policy, or other governing instruments: (a) withholding taxes, unemployment compensation or social security benefits; (b) all pension, profit-sharing, savings, stock purchase, stock bonus, stock ownership, stock option, and stock appreciation rights plans and agreements; (c) all employment, deferred compensation (whether funded or unfunded), salary continuation, consulting, retirement, early retirement, severance, reimbursement, bonus or collective bargaining plans and agreements; (d) all executive and other incentive compensation plans, programs, or agreements; (e) all group insurance and health contracts, policies and plans; and (f) all other incentive, welfare (including vacation and sick pay), retirement or employee benefit plans or agreements maintained or sponsored, participated in, or contributed to, by Frontier or any of its Subsidiaries for its current or former directors, officers, employees and agents.

All obligations and liabilities of Frontier and each of its Subsidiaries for all other forms of

34

compensation that are or may be payable to their current or former directors, officers, employees or agents, or pursuant to any Employee Plan, have been and are being paid to the extent required by applicable Law or by the plan or contract, and adequate actuarial accruals and reserves for payment therefor have been and are being made by Frontier and each of its Subsidiaries according to GAAP and generally accepted actuarial principles.

A Change in Recommendation effected in accordance with the provisions of Section 5.23 will not constitute a breach by Frontier of this Agreement. None of the information supplied or to be supplied by Frontier or any of its directors, officers, employees or agents for inclusion in the Registration Statement or the Proxy Statement/Prospectus shall, at the date the Proxy Statement/Prospectus is mailed to the unitholders of Frontier and, as the Registration Statement and the Proxy Statement/Prospectus may be amended or supplemented, at the time of the Members’ Meeting, contain any untrue statement of a material fact or omit to state any material fact with respect to Frontier necessary in order to make the statements therein with respect to Frontier, in light of the circumstances under which they are made, not misleading or necessary to correct any statement in any earlier communication with respect to the solicitation of any proxy for the Members’ Meeting. All documents that Frontier is responsible for filing with any Regulatory Agency in connection with the Merger shall comply with respect to Frontier in all material respects with the provisions of applicable Law.

(b) The Frontier Board has resolved to recommend to the Frontier unitholders that they approve this Agreement and the Merger and, subject to a Change in Recommendation in accordance with Section 5.23, shall submit to its unitholders this Agreement and any other matters required to be approved by its unitholders in order to carry out the purposes of this Agreement. Subject to a Change in Recommendation in accordance with Section 5.23, the Frontier Board shall (i) include in the Proxy Statement/Prospectus the recommendation of the Frontier Board that the unitholders of Frontier vote in favor of this Agreement, the Merger and the transactions contemplated

53

hereby, (ii) use its commercially reasonable efforts to obtain such unitholders approval of this Agreement, the Merger and the transactions contemplated hereby, (iii) perform such other acts as may reasonably be requested by EQBK to ensure that such member approval of this Agreement, the Merger and the transactions contemplated hereby are obtained, and (iv) cause the Proxy Statement/Prospectus to be mailed to the unitholders of Frontier as soon as practicable after the Registration Statement becomes effective with the SEC.

(c) If Frontier becomes aware prior to the Effective Time of any information that would cause any of the statements in the Proxy Statement/Prospectus to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, Frontier shall promptly inform EQBK thereof and take the necessary steps to correct the Proxy Statement/Prospectus.

Section 5.14 Benefit Plans.

(a) Frontier will take, and will cause each of its Subsidiaries to take, all action necessary to terminate any Employee Plan that is a Code § 401(a) qualified retirement plan (each a “Retirement Plan”) and related trust sponsored by Frontier or any of its Subsidiaries, effective no later than the date immediately before the Closing Date. Frontier will provide EQBK evidence or such other confirmation from Frontier which EQBK deems appropriate that each such Retirement Plan has been terminated as set forth in this Section 5.14(a) pursuant to duly authorized corporate action.

(b) At the direction of EQBK, Frontier will take, and will cause each of its Subsidiaries to take, all action necessary to terminate any Employee Plan that is an employee welfare benefit plan, as defined in ERISA § 3(1) (“Welfare Plan”), effective not later than immediately before the Closing.

(a) Frontier and each of its Subsidiaries will, with regard to any contract to which Frontier or any of its Subsidiary is a party identified by EQBK prior to the Calculation Date, cooperate with and take such actions as reasonably requested by EQBK to terminate any such contract on a date to be determined by EQBK, in its sole discretion. Any and all costs, fees, expenses, contract payments, penalties or liquidated damages necessary to be paid by Frontier or any of its Subsidiaries in connection with the termination of any contract, regardless of whether such contract is identified by EQBK, shall be accrued or paid by Frontier or its Subsidiaries on or prior to the Calculation Date in accordance with this Section 5.15(a). For the avoidance of doubt, EQBK will not pay or be responsible for the payment of any costs, fees, expenses, contract payments, penalties or liquidated damages in connection with the termination of any contract.

54

(b) Frontier and each of its Subsidiaries will cooperate with EQBK in EQBK’s negotiation in good faith of a reasonable settlement of the termination of Frontier’s and/or each of its Subsidiaries’ data processing/technology contracts listed on Frontier Confidential Schedule 5.15(b) and Frontier and each of its Subsidiaries will take such actions as reasonably requested by EQBK in connection with the termination of such contracts, to ensure that if the Merger occurs, the data procession/technology contracts listed on Frontier Confidential Schedule 5.15(b) will be terminated in connection with the consummation of the Merger or the conversion of the Bank’s systems to those of Equity Bank, as directed by EQBK; provided, that any and all costs, fees, expenses, contract payments, penalties or liquidated damages necessary to be paid by Frontier or any of its Subsidiaries in connection with the termination of such data processing and technology contracts shall be accrued or paid by Frontier or its Subsidiaries on or prior to the Calculation Date in accordance with this Section 5.15(b).

Section 5.17 Regulatory and Other Approvals. Frontier, at its own expense, will promptly file or cause to be filed applications for all regulatory approvals required to be obtained by Frontier in connection with this Agreement and the other agreements contemplated hereby. Frontier will promptly furnish EQBK with copies of all such regulatory filings and all correspondence for which confidential treatment has not been requested.

The Members’ Representative and EQBK shall each have a period of at least fifteen (15) Business Days prior to the due date (and prior to filing such Pre-Closing Tax Return) for such Pre-Closing Tax Return to review a draft of each such Pre-Closing Tax Return and shall allow the Members’ Representative and EQBK to review, comment and reasonably approve without undue delay upon each such Pre-Closing Tax Return. To the extent applicable, the Pre-Closing Tax Returns shall report the Integrated Mergers as a “reorganization” described in Section 368(a) of the Code.

(b) For purposes of this Agreement, in the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes other than property or ad valorem Taxes of Frontier or any of its Subsidiaries for the portion of the Straddle Period ending on the Closing Date shall be determined on an interim closing of the books as of the close of business on the Closing Date and the amount of all property or ad valorem Taxes shall be determined for that portion of the Straddle Period ending on the Closing Date equal to the amount of such Tax for the entire Straddle Period multiplied by a fraction the numerator of which is the number of the days from the beginning of the Straddle Period through the end of the Closing Date and the denominator of which is the total number of days in the entire Straddle Period.

(c) All transfer, documentary, sales, use, stamp, registration and other similar Taxes and all conveyance fees, recording charges and other similar fees and charges (including any penalties and interest) incurred in connection with the consummation of the transactions contemplated by this Agreement, if any, shall be paid by Frontier when due, and Frontier will, at its own expense, file all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges, and, if required by applicable Law. To the extent required by Law, EQBK will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation.

(d) Frontier and its Subsidiaries agree, upon request, to use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(e) In the event of any audit or exam of Frontier’s or its Subsidiaries’ federal or state Tax Returns (i) prior to the consummation of the Integrated Mergers, EQBK and Frontier shall cooperate regarding any such audit or exam and Frontier shall not settle the same without the consent of EQBK, which consent will not be unreasonably withheld; and (ii) after the Effective Time, EQBK may settle any such audit in any matter that it determines is appropriate and shall pay all amounts due with respect to any such settlement.

56

Frontier and its Subsidiaries shall not take or cause to be taken any action that would cause to be untrue (or fail to take or cause not to be taken any action that would cause to be untrue) any of the certifications, representations, warranties and covenants included in the Frontier Certificate.

Section 5.20 Disclosure Schedules. At least ten (10) days prior to the Closing, Frontier agrees to provide EQBK with supplemental disclosure schedules reflecting any material changes thereto between the date of this Agreement and the Closing Date. Delivery of such supplemental disclosure schedules shall not cure a breach or modify a representation or warranty of this Agreement.

Section 5.21 Transition.

(a) The senior officers of Frontier and the Bank agree to meet with senior officers of EQBK as reasonably requested by EQBK to review the financial and operational affairs of the Bank, and to the extent permitted by applicable Law, each of Frontier and the Bank agrees to give due consideration to EQBK’s input on such matters, consistent with this Section 5.21, with the understanding that EQBK shall in no event be permitted to exercise control of Frontier or the Bank prior to the Effective Time and, except as specifically provided under this Agreement, Frontier and the Bank shall have no obligation to act in accordance with EQBK’s input. Commencing after the date hereof and to the extent permitted by applicable Law, EQBK, Frontier and the Bank shall use their commercially reasonable efforts to plan the integration of Frontier and the Bank with the businesses of EQBK and their respective affiliates to be effective as much as practicable as of the Closing Date; provided, however, that in no event shall EQBK or its affiliates be entitled to control Frontier or the Bank prior to the Effective Time.

EQBK shall provide such assistance of its personnel as Frontier and the Bank shall request to permit Frontier and the Bank to comply with their obligations under this Section 5.21.

57

(b) Following receipt of all regulatory approvals required for the consummation of the transactions contemplated by this Agreement, each of Frontier and the Bank shall use its commercially reasonable efforts, and shall use its commercially reasonable efforts to cause its agents to, permit EQBK to take all reasonable actions that EQBK deems necessary or appropriate, and to cooperate and to use its commercially reasonable efforts to cause its agents to cooperate in the taking of such actions, to enable EQBK, after the Closing, to satisfy the applicable obligations under §§302, 404 and 906 of the Sarbanes-Oxley Act of 2002 (the “SOA”) and the other requirements of the SOA with respect to Frontier and the Bank, including establishing and maintaining adequate disclosure controls and procedures and internal controls over financial reporting as such terms are defined in the SOA. Any such actions shall be at the expense of EQBK.

(b) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the approval of the Frontier unitholders, in the event that Frontier receives a bona fide Acquisition Proposal that is not received in violation of this Section 5.23, Frontier and the Frontier Board may participate in discussions or negotiations with, or furnish any information to, any Person making such Acquisition Proposal and its

58

agents and representatives or potential sources of debt financing that need to be involved in such discussion, provided that (i) the Frontier Board determines in good faith, after consultation with its counsel and financial advisor, that such Person is reasonably likely to submit to Frontier a Superior Proposal, and (ii) that failure to take such action would reasonably be expected to be inconsistent with their fiduciary duties; provided, however, that, prior to providing any nonpublic information to such Person or participating in discussions or negotiations with such Person, Frontier shall have entered into a confidentiality agreement with such Person on terms that are substantially similar to the confidentiality provisions of the Confidentiality Agreement and that any nonpublic information concerning Frontier and its Subsidiaries provided to such Person, to the extent not previously provided to EQBK, is promptly provided to EQBK. In addition, nothing herein shall restrict Frontier from complying with its disclosure obligations with regard to any Acquisition Proposal under applicable Law.

(c) Frontier will promptly (and in any event within 48 hours) notify EQBK of the receipt by Frontier of any Acquisition Proposal, which notice shall include the material terms of and identity of the Person(s) making such Acquisition Proposal. Frontier will (subject to the fiduciary duties of the members) keep EQBK reasonably informed of the status and material terms and conditions of any such Acquisition Proposal and of any material amendments or proposed material amendments thereto and will promptly notify EQBK of any determination by the Frontier Board that such Acquisition Proposal constitutes a Superior Proposal.

(d) The Frontier Board may, at any time prior to obtaining the approval of the Frontier unitholders, (i) approve, endorse or recommend a Superior Proposal or enter into a definitive agreement with respect to a Superior Proposal or (ii) modify or amend in a manner adverse to EQBK or withdraw Frontier Recommendation ((i) or (ii) above being referred to as a “Change in Recommendation”), provided that (x) prior to such Change in Recommendation, the Frontier Board shall determine, in good faith (after consultation with its counsel), that the failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable Law and (y) such Change in Recommendation is in connection with a Superior Proposal and such Superior Proposal has been made and has not been withdrawn and continues to be a Superior Proposal after taking into account any action taken by EQBK pursuant to Section 5.23(e).

(e) Notwithstanding anything to the contrary contained in this Agreement, Frontier may not terminate this Agreement to enter into a definitive agreement with respect to a Superior Proposal unless (i) it notifies EQBK in writing of its intention to take such action at least five (5) Business Days prior to taking such action, specifying the material terms of any applicable Superior Proposal, identifying the Person(s) making such Superior Proposal and providing EQBK an unredacted copy of all of the agreements with the party making such Superior Proposal, (ii) EQBK does not make, after being provided with reasonable opportunity to negotiate with Frontier and its agents and representatives, within such five (5) Business Day period, irrevocable adjustments in the terms and conditions of this Agreement that the Frontier Board determines, in good faith after consultation with its counsel and financial advisors, is at least as favorable to Frontier’s unitholders as such Superior Proposal and (iii) Frontier is not in material breach of this Section 5.23.

(a) At the Effective Time, EQBK may, in its sole and absolute discretion, either discontinue the employment of one or more current employees of Frontier or any of its Subsidiaries (each a “Terminated Employee”), or continue the employment of one or more current employees of Frontier or any of its Subsidiaries (each a “Continuing Employee”). EQBK shall consult with the Chief Executive Officer of Frontier with respect to the termination of any such employees in connection with the Closing. Subject to the right of subsequent amendment, modification, replacement or termination in the sole discretion of EQBK, each Continuing Employee shall be entitled, as an employee of EQBK or its Subsidiaries, to participate in the employee benefit plans of EQBK provided to similarly situated employees of EQBK or its Subsidiaries, if such Continuing Employee shall be eligible and, if required by the terms of such plans, selected for participation therein under the terms thereof and makes any required contributions. All such participation shall be subject to such terms of such plans as may be in effect from time to time and this Section 6.07 is not intended to give any Continuing Employee any rights or privileges superior to those of other similarly situated employees of EQBK or its Subsidiaries. The provisions of this Section 6.07 shall not be deemed or construed so as to provide duplication of similar benefits but, subject to that qualification, EQBK shall, for purposes of vesting and any age or period of service requirements for commencement of participation with respect to any employee benefit plans in which a Continuing Employee may participate (excluding any defined benefit pension plan), credit each Continuing Employee with his or her term of service with Frontier or any of its Subsidiaries to the extent such service was recognized under the analogous Employee Plan of Frontier or any of its Subsidiaries.

(b) Terminated Employees and Continuing Employees will be eligible to receive the severance set forth on EQBK Confidential Schedule 6.07, subject to the satisfaction of the terms and condition set forth on such schedule.

(c) If Continuing Employees become eligible to participate in a medical, dental or health plan of EQBK upon termination of any such analogous plan of Frontier or the Bank, EQBK shall use commercially reasonable efforts to cause each such plan of EQBK to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of EQBK, and (ii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such Continuing Employee on or after the Effective Time, in each case to the extent such employee had satisfied any similar limitation or requirement under an analogous plan prior to the Effective Time for the plan year in which the Effective Time occurs.

(d) Nothing in this Agreement shall confer upon any employee, officer, director, independent contractor or consultant of Frontier or any of its Subsidiaries or Affiliates any right to continue in the employ or service of the Surviving Entity, EQBK, or any Subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, Frontier, EQBK or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Frontier or any of its Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Employee Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity or any of its Subsidiaries or Affiliates to amend, modify or terminate any particular Employee Plan or any other

62

benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 10.21, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person, including any current or former employee, officer, director, independent contractor or consultant (or any spouse or dependent of such individual) of Frontier or any of its Subsidiaries or Affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 6.09 Access to Properties and Records. To the extent permitted by applicable Law, and solely for the purposes of verifying the representations and warranties of EQBK and preparing for the Merger and the other matters contemplated by this Agreement, EQBK shall, and shall cause each of its Subsidiaries to, upon reasonable notice from Frontier to EQBK (a) afford the employees and officers and authorized representatives (including legal counsel, accountants and consultants) of Frontier, who enter into a non-disclosure agreement with EQBK in a form acceptable to EQBK, reasonable access to the properties, books and records of EQBK and its Subsidiaries during normal business hours in order that Frontier may have the opportunity to make such reasonable investigation of the affairs of EQBK and its Subsidiaries, and (b) furnish Frontier with such additional financial and operating data and other information as to the business and properties of EQBK as Frontier shall, from time to time, reasonably request. Frontier shall use commercially reasonable efforts to minimize any interference with EQBK’s business operations during any such access. Neither EQBK nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of EQBK’s customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any Law, Order, fiduciary duty or binding agreement entered into prior to the date of this Agreement.

63

Section 6.13 Tax-free Reorganization Opinion. An authorized officer of EQBK shall execute and deliver to Norton Rose Fulbright US LLP and Fenimore Kay Harrison LLP, respectively, certificates (the “EQBK Certificate”) containing appropriate representations and covenants, reasonably satisfactory in form and substance to each counsel, at such time or times as may be reasonably requested by each counsel, including the Closing Date (and, if requested, as of the date on which the Registration Statement is declared effective by the SEC), in connection with each counsel’s delivery of an opinion with respect to the Tax treatment of the Integrated Mergers pursuant to Section 7.10 and Section 8.14, and EQBK and Merger Sub shall also provide such other information as reasonably requested by each counsel for purposes of rendering the opinions described in Section 7.10 and Section 8.14. EQBK and its Subsidiaries shall not take or cause to be taken any action that would cause to be untrue (or fail to take or cause not to be taken any action that would cause to be untrue) any of the certifications, representations, warranties and covenants included in the EQBK Certificate.

Section 6.14 Directors’ and Officers’ Indemnification and Insurance.

(a) By virtue of the occurrence of the Integrated Mergers, EQBK and Equity Bank shall, from and after the Effective Time, succeed to Frontier’s and the Bank’s obligations with respect to indemnification or exculpation now existing in favor of the managers, directors, officers, employees and agents of Frontier and the Bank, respectively, as provided in their operating agreements, articles or certificates of organization or incorporation, bylaws, indemnification agreements or otherwise in effect as of the date of this Agreement with respect to matters occurring prior to the Effective Time (collectively, the “Existing Indemnification Obligation”).
