d)Non-Qualifying Termination. Notwithstanding any other provision of this Plan to the contrary, nothing in this Plan shall be construed to require the Company to pay any of the severance benefits under this Plan to an Eligible Executive if the Eligible Executive terminates employment with the Company under any circumstances that do not constitute a Qualifying Termination or a Qualifying CIC Termination.

4.Amount and Payment of Benefits upon a Qualifying Termination.

Subject to Sections 6 (Code § 280G potential carve-back) and 9(a) (Release requirements) of this Plan, an Eligible Executive who incurs a Qualifying Termination and is not eligible to receive severance benefits pursuant to Section 5 (Qualifying CIC Termination) shall be entitled to receive the severance benefits described below in this Section 4:

a)Payment. Unless otherwise provided herein, an Eligible Executive who incurs a Qualifying Termination shall receive severance payments in an amount equal to the sum of:

i.the product of the Applicable Qualifying Termination Severance Multiplier multiplied by the Eligible Executive's annual base salary as of the Eligible Executive's Termination Date;

ii.the product of the Applicable Qualifying Termination Severance Multiplier multiplied by the amount that the Eligible Executive would have received as an annual bonus under the Annual Incentive Plan for the plan year in which the Termination Date occurs, if an "at target" level of performance were achieved for such plan year and the Eligible Executive had remained employed through the end of the applicable performance year; and

iii.the product of the Applicable Qualifying Termination COBRA Multiplier multiplied by the Company-paid portion of the COBRA continuation premium cost to cover the Eligible Executive and his or her eligible dependents, if any, for one (1) month under the Company's health, vision and dental plans in effect as of the date of the Qualifying Termination. Such amount will include the Company-paid portion of the cost of the premiums for coverage of the Eligible Executive's dependents if, and only to the extent that, such dependents were enrolled in a health, vision or dental plan sponsored by the Company before the Qualifying Termination.

The severance payments made pursuant to this Section 4(a) shall be paid ratably over six (6) months, in accordance with the Company's normal payroll practices, commencing with the payroll period following the date on which the Release requirements of Section 9(a) are satisfied and in no event later than seventy-five (75) days after the Termination Date.

Notwithstanding any other provision of this Plan, if the Eligible Executive is a Specified Employee on his or her Termination Date, any portion of the severance payments under this Section 4(a) which may constitute non-exempt "nonqualified deferred compensation" subject to Code Section 409A shall be delayed until the earlier of (i) the first day after six (6) months following such Termination Date, as determined by the Company for the avoidance of penalties and/or excise taxes under Code Section 409A; or (ii) the date the Eligible Executive dies following such Termination Date.

b)Additional Payment. In addition to the severance payments made pursuant to Section 4(a), an Eligible Executive who incurs a Qualifying Termination shall also be entitled to receive a pro rata portion of the annual incentive bonus that the Eligible Executive would have received under the Annual Incentive Plan (or other annual incentive plan then in use by the Company) for the performance year during which his or her Termination Date occurs if the Eligible Executive had remained employed through the end of such performance year. The amount of such pro rata portion shall be the amount that the Eligible Executive would have received if the Eligible Executive had remained employed through the end of the applicable performance year, divided by three hundred and sixty-five (365), multiplied by the number of days between the first day of the performance year and the Eligible Executive's Termination Date. The severance payment eligible to be paid pursuant to this Section 4(b), if any, shall be paid in a single lump-sum cash payment, less all applicable withholding taxes, at the same time as the annual bonus payments are paid to other active bonus plan participants, and in no event later than the end of the calendar year in which the level of performance goal achievement is determined and certified by the Committee.

c)Outplacement Services. The Company shall reimburse the Eligible Executive for all reasonable and well-documented expenses directly relating to outplacement counseling services obtained by the Eligible Executive during the eighteen (18) month period following the Eligible Executive's Qualifying Termination.

provide the outplacement counseling; however, the Company's obligation to reimburse the Eligible Executive for such expenses shall not exceed $25,000. Reimbursement shall be made as soon as practicable after submission of appropriate expense reports with the Company, but in no event later than the end of the Eligible Executive's taxable year following the year in which the expense for outplacement counseling services was incurred.

d)Equity Award Vesting. An Eligible Executive who incurs a Qualifying Termination shall vest, if at all, in any and all previously granted stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units, deferred cash or any other form of equity awards issued by the Company and held by the Eligible Executive on his or her Termination Date (collectively, "Equity Awards") in accordance with the terms and conditions of the plan(s) and award agreements pursuant to which such Equity Awards are governed.

5.Amount and Payment of Benefits upon a Qualifying CIC Termination.

Subject to Sections 6 (Code § 280G potential carve-back) and 9(a) (Release requirements) of this Plan, an Eligible Executive who incurs a Qualifying CIC Termination and is eligible to receive the following severance benefits on account thereof, shall be entitled to receive the severance benefits described in this Section 5 in lieu of any severance benefits that the Eligible Executive is eligible to receive pursuant to Section 4 of this Plan:

a)Payment. Unless otherwise provided herein, an Eligible Executive who incurs a Qualifying CIC Termination shall receive a severance payment in an amount equal to the sum of:

i.the product of the Applicable Qualifying CIC Termination Severance Multiplier multiplied by the Eligible Executive's annual base salary as of the Eligible Executive's Termination Date;

ii.the product of the Applicable Qualifying CIC Termination Severance Multiplier multiplied by the amount that the Eligible Executive would have received as an annual bonus under the Annual Incentive Plan for the plan year in which the Termination Date occurs, if an "at target" level of performance were achieved for such plan year and the Eligible Executive had remained employed through the end of the applicable performance year;

iii.the product of the Applicable Qualifying CIC Termination COBRA Multiplier multiplied by the Company-paid portion of the COBRA continuation premium cost to cover the Eligible Executive and his or her eligible dependents, if any, for one (1) month under the Company's health, vision and dental plans in effect as of the date of the Qualifying CIC Termination. Such amount will include the Company-paid portion of the cost of the premiums for coverage of the Eligible Executive's dependents if, and only to the extent that, such dependents were enrolled in a health, vision or dental plan sponsored by the Company before the Qualifying CIC Termination; and

iv.a pro rata portion of the annual incentive bonus that the Eligible Executive would have received under the Annual Incentive Plan (or other annual incentive plan then in use by the Company) for the performance year during which his or her Termination Date occurs as if the Eligible Executive had remained employed

through the end of such performance year and if an "at target" level of performance were achieved for such performance year. The amount of such pro rata portion shall be the amount that the Eligible Executive would have received if the Eligible Executive had remained employed through the end of the applicable performance year and if an "at target" level of performance were achieved for such performance year, divided by three hundred and sixty-five (365), multiplied by the number of days between the first day of the performance year and the Eligible Executive's Termination Date.

The severance payment pursuant to this Section 5(a) shall be paid in a single lump-sum cash payment, less all applicable withholding taxes within the sixty (60) day period following the Eligible Executive's Termination Date. Notwithstanding any other provision of this Plan, if the Eligible Executive is a Specified Employee on his or her Termination Date, any portion of the severance payment under this Section 5(a) which may constitute non-exempt "nonqualified deferred compensation" subject to Code Section 409A shall be delayed until the earlier of (i) the first day after six (6) months following such Termination Date, as determined by the Company for the avoidance of penalties and/or excise taxes under Code Section 409A, or (ii) the date the Eligible Executive dies following such Termination Date.

b)Outplacement Services. The Company shall reimburse the Eligible Executive for all reasonable and well-documented expenses directly relating to outplacement counseling services obtained by the Eligible Executive during the eighteen (18) month period following the Eligible Executive's Qualifying CIC Termination. The Eligible Executive may select the organization that will provide the outplacement counseling, however, the Company's obligation to reimburse the Eligible Executive for such expenses shall not exceed $25,000. Reimbursement shall be made as soon as practicable after submission of appropriate expense reports with the Company but in no event later than the end of the Eligible Executive's taxable year following the year in which the expense for outplacement counseling services was incurred.

c)Equity Award Vesting. An Eligible Executive who incurs a Qualifying CIC Termination shall vest, if at all, in any and all previously granted Equity Awards in accordance with the terms and conditions of the plan(s) and award agreements pursuant to which such Equity Awards are governed.

In the event that the severance payments, distributions or benefits to be made by the Company to or for the benefit of the Eligible Executive (whether paid, payable, distributed, distributable or provided pursuant to the terms of this Plan, under some other plan, agreement, or arrangement, or otherwise) ("Payments") (i) constitute "parachute payments" within the meaning of Code Section 280G and (ii) but for this Section 6 would be subject to the excise tax imposed by Code Section 4999 (the "Excise Tax"), then the Payments to the Eligible Executive shall be either: (a) delivered in full, or (b) delivered after reducing the Payments $1 below the safe harbor limit (as described in Code Section 280G(b)(2)(A)(ii)) which would result in no portion of the Payments being subject to the Excise Tax. The choice between (a) and (b) shall depend upon whichever of the foregoing amounts, taking into account the applicable federal, state, and local income taxes and the Excise Tax, results in the receipt by the Eligible Executive, on an after-tax basis, of the greater amount, notwithstanding that all or some portion of the Payments may be taxable under Code Section 4999. In the event that the Payments are required to be reduced by this paragraph, any amount payable pursuant to Sections 4 or 5 shall be reduced, first by reducing all Payments being made pursuant to Sections 4(a) through (b) or 5(a) that do not constitute "nonqualified

deferred compensation" within the meaning of Code Section 409A (in the order designated by the Eligible Executive), second, by reducing all Payments other than those made pursuant to Sections 4(a) through (b) or 5(a) that do not constitute "nonqualified deferred compensation" within the meaning of Code Section 409A (in the order designated by the Eligible Executive), and third, reducing all Payments that constitute "nonqualified deferred compensation" within the meaning of Code Section 409A, with the latest of such scheduled payments being reduced first. CrossFirst's accounting firm shall make all determinations required by this paragraph, and CrossFirst and the Eligible Executive shall cooperate with each other and the accounting firm and shall provide necessary information so that the accounting firm may make all such determinations. CrossFirst shall pay all of the fees of the accounting firm for services performed by the accounting firm as contemplated in this Section 6.

7.Administration/Amendment/Termination.

a)Administrator. The Administrator has the sole discretionary authority to construe and interpret this Plan and to make any and all determinations related to administration of this Plan, including all questions of eligibility for participation and benefits, to the maximum extent permitted by law. The decisions, actions and interpretations of the Administrator are final and binding on all parties. The Administrator may delegate any of its duties under the Plan to such individuals or entities from time to time as it may designate.

b)Amendment. The Committee expressly reserves the right to amend this Plan, in whole or in part, at any time and in any way it determines to be advisable; provided that if the amendment will become effective during either the General Term or the CIC Term (as applicable to an Eligible Executive) then in progress (which, for this purpose, shall not include any renewal terms) and will materially and adversely affect the rights of any Eligible Executive under the Plan, the Company must obtain the Eligible Executive's written consent to the amendment. Notwithstanding the foregoing, any amendment to the definition of "Change in Control" made to the Equity Plan before a Change in Control or Potential Change in Control has occurred will not be deemed to adversely affect the rights of any Eligible Executives. Further, in no event shall a notification to an Eligible Executive notifying him or her that his or her participation in the Plan will terminate at the end of the General Term or CIC Term (as applicable) then in progress constitute an amendment to the Plan requiring such Eligible Executive's prior written consent.

c)Termination. An Eligible Executive's right under this Plan to receive severance benefits upon a Qualifying Termination shall commence upon the Effective Date and shall continue in effect through the first anniversary of the Effective Date (the "Initial General Term"). An Eligible Executive's right under this Plan to receive severance benefits upon a Qualifying CIC Termination shall commence upon the Effective Date and shall continue in effect through the third anniversary of the Effective Date (the "Initial CIC Term"). Unless terminated prior to either the end of the Initial General Term or the Initial CIC Term, both the Initial General Term and the Initial CIC Term shall be automatically renewed for successive one-year periods commencing at the end of the Initial General Term and Initial CIC Term, respectively, and on each anniversary date thereafter. For purposes of this Plan, any reference to the "General Term" shall include the Initial General Term and any extension thereof and any reference to the "CIC Term" shall include the Initial CIC Term and any extension thereof. Notwithstanding the foregoing, the Committee reserves the right to terminate this Plan by providing written notice to each Eligible Executive at least ninety (90) days prior to the end of the General Term or CIC Term that such term will not be extended, and if such notice is timely given, the Plan will terminate with respect to the General Term or CIC Term at the end of the General Term or CIC Term, as applicable, then in effect;

provided that if the CIC Term expires or is scheduled to expire during the Protection Period, the CIC Term shall be deemed to have been extended through, and the Plan shall continue in full force and effect and shall not terminate or expire until the first day immediately following the expiration of the Protection Period (as defined below). A proper termination of this Plan automatically shall effect a termination of all the Eligible Executive's rights and benefits hereunder without further action or notice; provided, however, no termination shall reduce or terminate any Eligible Executive’s right to receive, or continue to receive, any benefits that became payable in respect of a termination of employment that occurred prior to the date of such termination.

8.Claims for Benefits.

Any claim for benefits under this Plan shall be subject to the claims procedures contained in Appendix B attached to this Plan.

9.Miscellaneous Provisions.

a)Release and Adherence to Restrictive Covenants. In consideration of and as a condition precedent to receiving any of the severance benefits in the event of a Qualifying Termination or Qualifying CIC Termination under this Plan, no severance payment nor severance benefit shall be required to be made or provided under Sections 4 or 5 unless and until the Eligible Executive (i) executes and delivers to the Company a release of all claims in such form as requested by the Company within twenty-two (22) days following the Eligible Executive's Date of Termination (or any such longer period if required by applicable law and communicated to the Eligible Executive), (ii) does not revoke the release during the seven (7) day period following the date that the Eligible Executive executed the release (or any such longer period if required by applicable law and communicated to the Eligible Executive), and (iii) adheres to and remains in compliance with the restrictive covenants set forth in Appendix A or any employment agreement to which the Eligible Executive may be subject, each of which may apply for a period of time after the termination of the Eligible Executive's employment as described therein. To the extent any Equity Award award agreement between the Company and the Eligible Executive contains restrictive covenants, such Equity Award will be subject to the restrictive covenants therein and not any restrictive covenants contained in Appendix A of this Plan.

b)Waiver. The failure of the Company to enforce at any time any of the provisions of this Plan, or to require at any time performance of any of the provisions of this Plan, shall in no way be construed to be a waiver of these provisions, nor in any way to affect the validity of this Plan or any part thereof, or the right of the Company thereafter to enforce every provision.

c)Benefits Not Transferable. Except as may be required by law, no benefit eligible to be payable under this Plan to any Eligible Executive shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any attempt to alienate, sell, transfer, assign, pledge, encumber or charge all or any part of the benefit shall be void; provided, however, that if a terminated Eligible Executive dies before the end of the period over which such Eligible Executive is entitled to receive severance benefits under this Plan, the severance benefits payable hereunder shall be paid to the estate of such Eligible Executive or to the person who acquired the rights to such benefits by bequest or inheritance (the "Beneficiary"), provided such Beneficiary satisfies the release requirements in Section 9(a). Except as may be provided by law, no benefit shall in any manner be subject to the debts, contracts, liabilities,

engagements or torts of any Eligible Executive, nor shall it be subject to attachment or legal process for, or against, the Eligible Executive and the same shall not be recognized under this Plan.

d)Successors of the Company. This Plan shall bind any successor of the Company, its assets or its businesses (whether direct or indirect, by purchase, merger, consolidation or otherwise), in the same manner and to the same extent that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by this Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the Company’s obligations under this Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. The term "Company," as used in this Plan, shall mean the Company as heretofore defined and any successor or assignee to the business or assets which by reason hereof becomes bound by this Plan.

e)No Contract of Employment. The definitions and criteria set forth herein are solely for the purpose of defining Plan eligibility. No legal rights to employment are created or implied by this Plan, nor are any conditions or restrictions hereby placed on termination of employment. Unless the employee has a written employment agreement binding on the Company that provides otherwise, employment with the Company is employment-at-will. As such, termination of employment may be initiated by the Eligible Executive or by the Company at any time for any reason that is not unlawful, with or without Cause.

f)Governing Law. To the extent not pre-empted by federal law, this Plan shall be construed, administered and governed in accordance with and governed by the laws of the State of Kansas, without regard to any conflict of law principles. Subject to Section 8(h), any action concerning this Plan shall be brought in a court of competent jurisdiction in Johnson County, Kansas, and each party consents to the venue and jurisdiction of such court.

g)Entire Plan. This Plan constitutes the Company's entire Executive Severance Plan for the Eligible Executive and, except as provided in Section 9(h) and Section 10 of this Plan, supersedes any and all previous representations, understandings and plans with respect to general severance for the Eligible Executives, and any such representations, understandings and plans with respect to Eligible Executive severance are hereby canceled and terminated in all respects.

h)Severability and Interpretation. Whenever possible, each provision of this Plan and any portion hereof shall be interpreted in such a manner as to be effective and valid under applicable law, rules and regulations. If any covenant or other provision of this Plan (or portion thereof) shall be held to be invalid, illegal, or incapable of being enforced, by reason of any rule of law, rule, regulation, administrative order, judicial decision or public policy, all other conditions and provisions of this Plan shall, nevertheless, remain in full force and effect, and no covenant or provision shall be deemed dependent upon any other covenant or provision (or portion) unless so expressed herein. The parties hereto desire and consent that the court or other body making such determination shall, to the extent necessary to avoid any unenforceability, so reform such covenant or other provision or portion of this Plan to the minimum extent necessary so as to render the same enforceable in accordance with the intent herein expressed.

i)No Mitigation Required. The Eligible Executive shall not be required to mitigate the amount provided for in Sections 4 or 5 of this Plan by seeking other employment or otherwise, nor shall the amount of any payment or benefit provided for in Section 4 of this Plan be reduced by any compensation earned by the Eligible Executive as the result of employment by another employer after the date of termination, or otherwise.

j)Validity. If any provision of this Plan is held invalid, void or unenforceable, the same shall not affect, in any respect whatsoever, the validity of any other provision of this Plan.

k)Captions and Titles. Captions and titles have been used in this Plan only for convenience, and in no way define, limit or describe the meaning of this Plan or any part thereof.

l)Section 409A Savings Clause. This Plan is intended to comply with the provisions of Section 409A of the Code, including the exceptions for short-term deferrals, separation pay arrangements, reimbursements and in-kind distributions, and shall be administered and interpreted in accordance with such intent. Without limiting the generality of the foregoing, any term or provision that is determined by the Administrator to have an ambiguous definition shall be interpreted, to the extent reasonable, to comply with Section 409A of the Code. Any reference in this Plan to a "termination of employment" or similar term or phrase shall be interpreted as a "separation from service" within the meaning of Section 409A of the Code. Each payment under this Plan shall be treated as a separate payment for purposes of Section 409A of the Code. In no event may an Eligible Executive, directly or indirectly, designate the calendar year of any payment to be made under this Plan. All reimbursements and in-kind benefits, including any taxable health, dental and vision benefits provided under this Plan that constitute deferred compensation within the meaning of Section 409A of the Code shall be made or provided in accordance with the requirements of Section 409A of the Code, including, without limitation, that (i) in no event shall reimbursements by the Company under this Plan be made later than the end of the calendar year next following the calendar year in which the applicable fees and expenses were incurred, provided that the Eligible Executive shall have submitted an invoice for such fees and expenses at least ten (10) days before the end of the calendar year next following the calendar year in which such fees and expenses were incurred; (ii) the amount of in-kind benefits that the Company is obligated to pay or provide in any given calendar year (other than medical reimbursements described in Treas. Reg. Section 1.409A-3(i)(1)(iv)(B)) shall not affect the in-kind benefits that the Company is obligated to pay or provide in any other calendar year; (iii) the Eligible Executive's right to have the Company pay or provide such reimbursements and in-kind benefits may not be liquidated or exchanged for any other benefit; and (iv) in no event shall the Company's obligations to make such reimbursements or to provide such in-kind benefits apply later than the end of the third year following the year in which the Eligible Executive's Termination Date occurred.

Notwithstanding the foregoing, any benefits received by an Eligible Executive pursuant to this Plan shall be in lieu of any general severance policy or other change in control severance plan maintained by the Company except to the extent any such substitution in severance benefits or payment timing would result in a violation of Code Section 409A.
