Termination by You. You may resign from your employment with Cerner at any time upon written notice to Cerner of your intention to resign from employment. Any resignation notice must be submitted to Cerner at least thirty (30) days prior to your intended last day of employment. Cerner, however, reserves the right either to accelerate your last day of employment or to allow your intended last day of employment to stand. If you resign with fewer than thirty (30) days’ notice, or if you actually leave Cerner’s employ prior to expiration of the notice period without the permission of Cerner, then you agree that (to the extent permitted by law) no Accrued Amounts from the date you submitted your resignation notice to your last day of employment will be owed or paid to you by Cerner. All other Accrued Amounts will be paid. You may also terminate your employment hereunder upon written notice to Cerner in the event of a Constructive Termination (before a Change in Control) or for Good Reason (after a Change in Control) and, subject to you satisfying your obligations under Paragraph 9.B.3 (Severance Agreement and Release), be entitled to certain severance and benefit compensation as provided in Paragraph 9.B.

Severance and Benefits.

Non-Change in Control - Termination by Cerner for other than an Ineligible Severance Event or Resignation following Constructive Termination. Subject to you satisfying your obligations under Paragraph 9.B.3. (Severance Agreement and Release), if, prior to a Change in Control or at any time after twelve (12) months following a Change in Control, (i) Cerner terminates your employment other than in connection with an Ineligible Severance Event or (ii) you resign from employment following a Constructive Termination, Cerner will within sixty (60) days (or later if required by Code Section 409A) of your termination of employment:

Pay you your Accrued Amounts; and

Commence severance payments to you equal to the sum of (i) two (2) year’s base salary (based on your annual base salary at the time of your termination), plus (ii) two (2) times the average annual cash bonus you received from Cerner during the three (3) years preceding the termination of your employment, less (iii) normal tax and payroll deductions. Such severance pay will be payable pro rata during the twenty-four (24) month severance term on Cerner’s regular paydays; and

Commence payments to you having an aggregate value equal to twenty-four (24) times the difference between the monthly COBRA continuation premium cost to cover you and your dependents (to the extent covered under Cerner's health, vision and dental the plans on the date of your termination of employment) under Cerner's health, vision and dental plans in effect as of the date of your termination and the monthly amount you were paying for such coverage at the effective date of your termination. Such payments will be payable pro rata during the twenty-four (24) month severance term on Cerner’s regular paydays. Notwithstanding the foregoing, if Cerner making payments under this Paragraph 9.B.1.c would violate the nondiscrimination rules applicable to non-grandfathered plans under the Affordable Care Act or result in the imposition of penalties under the Affordable Care Act, the parties agree to reform this Paragraph 9.B.1.c in a manner as is necessary to comply with the Affordable Care Act; and

With respect to outstanding equity awards:

Fully vest all outstanding unvested stock options or stock appreciation rights granted by Cerner to you and still held by you and all other outstanding equity-based compensation awards that are not intended to qualify as performance-based compensation under Code Section 162(m)(4)(C); provided that, any delays in the settlement or payment of such awards that are set forth in the applicable award agreement and that are required under Code Section 409A ("Section 409A") shall remain in effect; and

Cause all outstanding equity-based compensation awards that are intended to constitute performance-based compensation under Code Section 162(m)(4)(C) (excluding stock options and stock appreciation rights which will fully vest in accordance with Paragraph 9.B.1.d.i) to remain outstanding and vest or be forfeited in accordance with the terms of the applicable award agreements, if the applicable performance goals are satisfied.

Change in Control - Termination by Cerner for other than an Ineligible Severance Event or Resignation for Good Reason. Subject to you satisfying your obligations under Paragraph 9.B.3 (Severance Agreement and Release), if there is a Change in Control of Cerner and within twelve (12) months following the date such Change in Control becomes effective Cerner terminates your employment for any reason other than on account of an Ineligible Severance Event or you resign from employment with Good Reason, then Cerner will, within sixty (60) days (or later if required by Code Section 409A) of your termination of employment:

Pay you your Accrued Amounts;

Commence severance payments to you equal to the sum of (i) two (2) years’ base salary (based on your annual base salary at the time of your termination or resignation), plus (ii) two (2) times the average annual cash bonus you received from Cerner during the three (3) years preceding the termination or resignation of your employment, less (iii) normal tax and payroll deductions. Such severance pay will be payable in lump sum within sixty (60) days of the effective date of the termination of your employment;

Commence payments to you having an aggregate value equal to twenty-four (24) times the difference between the monthly COBRA continuation premium cost to cover you and your dependents (to the extent covered under Cerner's health, vision and dental plans on the date of your termination of employment) under Cerner's health, vision and dental plans in effect as of the date of your termination and the monthly amount you were paying for such coverage at the effective date of your termination. Such payments will be payable pro rata during the twenty-four (24) month severance term on Cerner’s regular paydays. Notwithstanding the foregoing, if Cerner's making payments under this Paragraph 9.B.2.c would violate the nondiscrimination rules applicable to non-grandfathered plans under the Affordable Care Act or result in the imposition of penalties under the Affordable Care Act, the parties agree to reform this Paragraph 9.B.2.c in a manner as is necessary to comply with the Affordable Care Act; and

Fully vest all outstanding unvested equity incentive awards granted to you under any Cerner equity incentive plans after June 1, 2005. For purposes of this Paragraph 9.B.2.d, any performance-based award shall become vested or settled assuming an "at-target" level of goal achievement had been attained.

Severance Agreement and Release. As a condition to your receiving severance in accordance with this Paragraph 9.B, upon your resignation or the termination of your employment, you agree to promptly execute and not revoke a written severance agreement, which release will be provided to you within ten (10) days of your termination date, containing normal and customary provisions, including but not limited to, a release releasing Cerner from any claims against Cerner related to your employment with Cerner that you might have at the time of or following the termination of your employment, and reasonable and customary representations and warranties.

Forfeiture and Reimbursement. Further, notwithstanding anything to the contrary in this Executive Severance Agreement, if you breach any confidentiality, non-competition or other material provision in

ERISA Claims Review Procedures. To the extent any severance payments described in this Paragraph 9.B are covered by the Employee Retirement Income Security Act of 1974, as amended, Claims Review Procedures are available from Cerner.

Compliance with Section 409A.

General Compliance. This Executive Severance Agreement and any severance payments contemplated to be made hereunder is intended to comply with Section 409A or an exemption thereunder and shall be construed and administered in accordance with Section 409A. Notwithstanding any other provision of this Executive Severance Agreement, payments provided under this Executive Severance Agreement may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments under this Executive Severance Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this Executive Severance Agreement shall be treated as a separate payment. Any payments to be made under this Executive Severance Agreement upon a termination of employment shall only be made upon a "separation from service" under Section 409A. Notwithstanding the foregoing, Cerner makes no representations that the payments and benefits provided under this Executive Severance Agreement comply with Section 409A, and in no event shall Cerner be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by you on account of non-compliance with Section 409A.

Specified Employees. Notwithstanding any other provision of this Executive Severance Agreement, if any payment or benefit provided to you in connection with your termination of employment is determined to constitute "nonqualified deferred compensation" within the meaning of Section 409A and you are determined to be a "specified employee" as defined in Section 409A(a)(2)(b)(i), then such payment or benefit shall not be paid until the first payroll date to occur following the six-month anniversary of the your termination date or, if earlier, on your death (the "Specified Employee Payment Date"). The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date shall be paid to you in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments shall be paid without delay in accordance with their original schedule.

Reimbursements. To the extent required by Section 409A, each reimbursement or in-kind benefit provided under this Executive Severance Agreement shall be provided in accordance with the following:

the amount of expenses eligible for reimbursement, or in-kind benefits provided, during each calendar year cannot affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year;

any reimbursement of an eligible expense shall be paid to you on or before the last day of the calendar year following the calendar year in which the expense was incurred; and

any right to reimbursements or in-kind benefits under this Executive Severance Agreement shall not be subject to liquidation or exchange for another benefit.

Partial Accelerated Vesting upon a Change in Control. In connection with a Change in Control, 50% of each outstanding and unvested equity incentive award granted to you under any Cerner equity incentive plan after June 1, 2005 and prior to the date of the Change in Control becomes effective will become vested on the date the Change in Control becomes effective. The remaining 50% of each such outstanding equity incentive award that has not yet vested will continue to vest according to its vesting schedule (unless your employment is

Modified 280G Carve-Back. Notwithstanding anything contained in this Executive Severance Agreement to the contrary, if on an after-tax basis the aggregate payments and benefits paid pursuant to Paragraph 9.B.2 or Paragraph 9.C would be larger if the portion of such payments and benefits constituting "parachute payments" under Code Section 280G were reduced by the minimum amount necessary to avoid the imposition of the excise tax under Code Section 4999, then such payments and benefits shall be reduced by the minimum amount necessary to avoid such excise tax.  Any such reduction shall occur in a manner that maximizes your economic position. In applying this principle, the reduction shall be made in a manner consistent with the requirements of Section 409A, and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis but not below zero. Any determination required under this Paragraph 9.D shall be made in writing in good faith by an accounting firm selected by Cerner, which is reasonably acceptable to you (the “Accountants”). Cerner and you shall provide the Accountants with such information and documents as the Accountants may reasonably request in order to make a determination under this Paragraph 9.D. Cerner shall be responsible for all fees and expenses of the Accountants.

409(a) Modifications. Notwithstanding anything to the contrary herein, Cerner may modify your Employment Agreement and this Executive Severance Agreement from time to time without your consent if Cerner’s legal counsel deems doing so to be advisable to comply with Section 409A of the Code and you agree that any such modifications shall be binding upon you.
