August 8, 2013

Dear Jonathan:

It is with great pleasure that I confirm in writing the terms and conditions of your promotion in this employment letter (“Employment Letter”), effective August 9, 2013 (the “Effective Date”).

Position: Your position will be Senior Vice President, Controller & Chief Accounting Officer of CareFusion Corporation (the “Company”), reporting to the Company’s Chief Financial Officer. In this position, you will be designated as the Company’s “principal accounting officer” and will be an “officer” of the Company for purposes of Section 16 of the Securities Exchange Act of1934, as amended.

Base Pay: Your initial annual base salary will increase to $260,000 (“Base Salary”) subject to review and modification at regular intervals, in accordance with standard Company practices. CareFusion employees are paid every other Friday, one week in arrears (one week behind the most current workweek you’ve completed). The official CareFusion workweek starts on Monday and runs through Sunday.

Management Incentive Plan: You will continue to be eligible to participate in our short-term incentive plan, which we call our Management Incentive Plan (“MIP”), pursuant to which cash incentive awards are typically paid on an annual basis. Your potential MIP incentive for fiscal year ending June 30, 2014 will increase to 45% of your Base Salary (the “MIP Bonus”), pro-rated for your length of service in this position during fiscal 2014. The actual MIP Bonus earned and paid in any year depends upon the achievement of Company and/or individual performance objectives as established and determined by the Human Resources and Compensation Committee of the Company’s Board of Directors (the “Committee”).

Long-Term Incentive Plan: Provided that the Effective Date is prior to August 15, 2013 (the “Grant Date”), you will receive a long term incentive award for fiscal 2014 equal to 90% of Base Salary (the “LTI Target”), or $234,000. The LTI Target is expected to be delivered based on the following mix: 50% stock options, 25% restricted stock units (“RSUs”) and 25% performance stock units (“PSUs”). Stock options and RSUs will vest in annual installments of 33.33% on each of the first three anniversaries of the Grant Date, and will be subject to the terms of the Company’s standard form of agreement applicable to such type of award (a “Grant Agreement”) and the Company’s Long-Term Incentive Plan (the “LTIP”). PSUs will vest at the end of a three-year performance period, subject to the Company attaining certain pre-established performance goals, and will be subject to the terms of the applicable Grant Agreement and the LTIP. The timing of the grant of these awards, the award values and terms are subject to the approval of the Committee.

Compensation plan participation and amounts paid are subject to the approval of the Committee. Standard terms and conditions apply.

Rewards: You and your eligible dependents will continue to be eligible to participate in the Company’s employee benefit plans consistent with an employee of your position.

Executive Severance Guidelines: If you accept this offer and your employment is terminated by the Company without “cause” or you terminate employment for “good reason”, you will be entitled to severance benefits in accordance with the Company’s Executive Severance Guidelines (the “Guidelines”) then in effect, subject to the Board’s discretion to modify or terminate the Guidelines or your participation thereunder. Under the current Guidelines, you would be eligible to receive severance payments equal to the sum of (i) one times (1X) your Base Salary for the year in which employment terminates (without regard to any reduction that gives rise to good reason) plus (ii) one times (1X) your two-year average actual MIP Bonus (or target MIP Bonus, if the actual MIP Bonus is indeterminable) for the fiscal year during which employment terminates and the immediately preceding fiscal year.

Executive Change in Control Severance Plan: If in connection with a “change in control” of the Company your employment is terminated by the Company without “cause” or by you for “good reason”, then you will be entitled to severance benefits in accordance with the Company’s Executive Change in Control Severance Plan (the “Severance Plan”) then in effect, subject to the Board’s discretion to modify or terminate the Severance Plan or your participation thereunder. Under the current Severance Plan, you would be eligible to receive severance payments equal to the sum of (i) one and a half times (1.5X) the sum of your Base Salary for the year in which your employment terminates (without regard to any reduction that gives rise to good reason) plus your target MIP bonus for the fiscal year during which your employment terminates and (ii) a pro-rated MIP Bonus for the year in which the termination occurs.

Prior to receiving any severance payments under the Guidelines or the Severance Plan (“Severance Payments”), you will be required to sign a timely waiver and release of liability in a form satisfactory to the Company and to comply with the Restrictive Covenants in order to receive any Severance Payments.

To the extent you are entitled to receive Severance Payments that constitute nonqualified deferred compensation subject to Section 409A of the Internal Revenue Code, and you are determined to be a “specified employee” for purposes of Section 409A, such amounts will be paid on the first day of the seventh month following separation from service or, if earlier, upon death.

You must agree to comply with certain Restrictive Covenants regarding confidential information; non-recruitment and non-solicitation of employees; non-solicitation of business; and non-disparagement. You must also agree to assist the Company with regard to legal and other matters pending during his employment or arising after termination. You must disclose and assign any inventions to the Company. The Company has the right to suspend Severance Payments and you must agree to return any previously paid amounts upon a violation of the Restrictive Covenants, in addition to any other legal remedies that may be available to the Company.

Terms: Employment with CareFusion is not for any definite period of time and is terminable, with or without notice, at the will of either you or the Company at any time for any reason. There shall be no contract, express or implied, of employment.

Confidentiality Agreement: Your employment is contingent upon signing the CareFusion Confidentiality Agreement, a copy of which is attached as Exhibit A.

Entire Agreement: You acknowledge that you do not, and have not, relied upon any representation or statement not set forth herein made by the Company, its agents or representatives. You and the Company acknowledge that this Employment Letter contains the entire understanding of you and the Company with respect to the matters set forth herein.

Jonathan, you may have some follow-up questions once you have had the opportunity to review the details of this offer. If you have any questions, please feel free to call Jim Hinrichs or Roger Marchetti. I look forward to your continued leadership to CareFusion.

Further, a breach of the covenants contained herein, may have implications under the terms of such other agreements, including but not limited to a forfeiture of equity awards and long-term cash compensation.
