OMNICARE, INC. SENIOR EXECUTIVE CHANGE IN CONTROL PLAN

This Senior Executive Change in Control Plan is effective as of May 22, 2013.

OBJECTIVE

Omnicare, Inc. (the “Company”) has adopted the Omnicare, Inc. Senior Executive Change in Control Plan (the “Plan”) to provide certain executives with the financial security to allow them to focus on the growth of the Company's business during a critical transition period. Executives must make important decisions that affect the livelihood of many employees and the overall performance of the Company. Moreover, in the event of a change-in-control, it is critical to the ongoing success of the Company to retain key leaders to ensure an effective transition. In order to free these executives to make decisions in a thoughtful and strategic manner, regardless of the personal consequences, the Company has provided them with this additional level of security. The Company further believes that the Plan will aid the Company in attracting and retaining highly qualified executives who are essential to its success.

PLAN OPERATION

Any decisions or determinations required to be made under the Plan shall be made by the Compensation Committee of the Company's Board of Directors (the “Committee”) or one or more executives of the Company to which authority is delegated by the Committee. The decisions and determinations of the Committee (and any executive to whom authority has been delegated) relating to the Plan are final and binding on all persons.

PARTICIPATION

Participation in the Plan is limited to the most senior executives of the Company and its subsidiaries as selected by the Committee (upon recommendation of the Company's Chief Executive Officer) or as selected by the Company's Chief Executive Officer if such authority is so delegated by the Committee. Notwithstanding anything contained herein, employees of the Company and its subsidiaries are not eligible to participate in the Plan and are excluded from coverage under the Plan if they are a party to an individual arrangement or a written employment agreement or other change-in-control payment policy or arrangement with the Company or any of its subsidiaries containing a change-in-control provision unless the Participant waives any rights to such change-in-control provisions in a manner deemed appropriate by the Committee. Any Qualifying Change-in-Control Termination that also qualifies for benefits under the Omnicare, Inc. Senior Executive Severance or the Omnicare Inc. Executive Severance Plan shall only receive benefits under this Plan and not under such severance plan.

Participation in the plan is limited to senior executives in one of the following two tiers:

Tier 1 - Executive Officers of the Company, as confirmed by the Compensation Committee and the full Board of Directors on an annual basis.

Tier 2 - Senior executives who are not Executive Officers, but whose ongoing employment would be critical in a transition should a Change-in-Control occur. Such executive must be selected as described above under “Participation”.

Payment of the Change-in-Control benefits may also be subject to the provisions of Section 409A of the Internal Revenue Code of 1986, as amended (“Code Section 409A”) discussed below.

Notwithstanding the other provisions of this Plan, in the event that any Change-in-Control or other benefits otherwise payable to the Participant (i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this paragraph, would be subject to the excise tax imposed by Section 4999 of the Code, then any other benefits shall be either (x) delivered in full, or (y) delivered as to such lesser extent which would result in no portion of such benefits being subject to excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income and employment taxes and the excise tax imposed by Section 4999 of the Code (and any equivalent state and local excise taxes), results in the receipt by the Participant on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Company and the Participant otherwise agree in writing, any determination required under this paragraph will be made by the Company and its advisors. Any reduction in payments and/or benefits required by this provision shall occur in the following order: (1) reduction of Change-in-Control payments; (2) reduction of vesting acceleration of equity awards; and (3) reduction of other benefits paid or provided to the Participant. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant for the Participant's equity awards. If two or more equity awards are granted on the same date, each award will be reduced on a pro-rata basis.

Any rights a Participant may have with respect to pension benefits, long-term performance awards, stock options, restricted stock and restricted stock units, deferred compensation, bonus payments or other employee or fringe benefits will be determined in accordance with the applicable Company plans, programs and/or policies.

If a Participant is rehired by the Company or any of its subsidiaries, any unpaid Change-in-Control benefits or payments will be forfeited. If a Participant is a terminated employee who is subsequently reinstated to employee status back to the date he or she was terminated (including reinstatement as the result of an appeal of a claim for disability benefits), any Change-in-Control payment made to a Participant must be repaid to the Company.

RESTRICTIVE COVENANTS

Any agreement that a Participant has entered into with the Company or a subsidiary that provides for nondisclosure of information, noncompetition with the Company or its subsidiaries and/or non-solicitation of the Company's and its subsidiaries' current or prospective clients, customers or employees (each, a “Restrictive Covenant Agreement”) shall remain in full force and effect following a Qualifying Termination, and Participant agrees to abide by the terms of any such agreement. The Company reserves all rights to enforce the provisions of any Restrictive Covenant Agreement. In the event that a Participant breaches any Restrictive Covenant Agreement, any unpaid benefits under the Plan will be forfeited (other than the Accrued Obligations or any other provision required by law).

(b) If a Participant's separation is covered by the provisions of the Workers Adjustment and Retraining Notification Act (WARN), any payments made to the Participant under provisions of that act will offset the Change-in-Control benefits calculated under the Plan.

(c) The Plan does not constitute a contract of employment. Nothing in this plan is to be construed as providing the Participant with a right to continued employment. A Participant's employment with the Company continues to be “at will” subject to the benefits provided herein upon a Qualifying Change-in-Control Termination.

(d) The Company shall withhold from any amounts payable under the Plan all federal, state, local or other taxes that are legally required to be withheld.

(f) The invalidity or unenforceability of any provision of the Plan shall not affect the validity or enforceability of any other provision of the Plan, which shall remain in full force and effect, and any prohibition or unenforceability in any jurisdiction, shall not invalidate or render unenforceable such provision in any other jurisdiction.

(g) The other benefits under the Plan shall constitute unfunded obligations of the Company. The Change-in-Control payments shall be made, as due, from the general funds of the Company. The Plan shall constitute solely an unsecured promise by the Company to provide such benefits to a Participant to the extent provided herein. For avoidance of doubt, any health benefits to which a Participant may be entitled under the Plan shall be provided under other applicable employee benefit plans of the Company.

(h) In addition to any compensation recovery (claw back) which may be required under any agreement between the Company and the Participant, law or regulation (including but not limited to any claw back required by Section 954 of the Dodd-Frank Act), Participant acknowledges and agrees that any compensation paid under this Plan is deemed to be subject to any claw back requirements as set forth in the Company's corporate governance guidelines or policies and to any similar successor provisions as may be in effect from time to time, including by reason of guidelines or policies adopted following the date of the Participant's Qualifying Change-in-Control Termination.

(i) By signing the Acknowledgement Form, the Participant agrees not to commence any action or suit related to Participant's employment by the Company or any arbitration related to this Plan: (i) more than six months after the termination of Participant's employment, if the action, suit or arbitration is related to the termination of Participant's employment, or (ii) more than six months after the event or occurrence on which Participant's claim is based, if the action, suit, or arbitration is based on an event or occurrence other than the termination of Participant's employment. Participant agrees to waive any statute of limitations that is contrary to this section.

(j) A Participant and the Company shall submit to mandatory, final and binding arbitration any controversy or claim arising out of, or relating to, this Plan or any breach hereof.

6

time such arbitration is conducted. Judgment upon the determination or award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Nothing in this section shall affect or limit in any way the Company's right to resort to a court for injunctive, equitable, or other relief for breach or threatened breach of Participant's obligation to the Company or otherwise relating to enforcement of any Restrictive Covenant Agreement or otherwise related to unfair competition or restrictive covenants.

(k) This Plan shall be governed by and construed in accordance with the substantive laws of the State of Ohio, without regard to the conflicts of law principles thereof. The Participant is deemed to agree (i) that any suit, proceeding or action at law or in equity (each, an “Action") arising out of or relating to this Plan must be instituted in state or federal court located within Hamilton County, Ohio, (ii) to waive any objection which he or she may have now or hereafter to the laying of the venue of any such Action, (iii) to irrevocably submit to the jurisdiction of any such Action, and (iv) to hereby waive any claims or defenses of inconvenient forum. The Company and the Participant irrevocably agrees that service of any and all process which may be served in any such Action may be served upon the Participant or the Company by registered mail and that such service shall be deemed effective service of process upon the Participant and the Company in any such Action. The Participant and the Company irrevocably agree that such service of process shall have the same force and validity as if service were made to the Participant or the Company according to the law governing such service in the State of Ohio, and waive all claims of error by reason of any such service.

Additionally, Participant agrees to return to the Company within five (5) days of the Company's written request any previously paid payments made pursuant to this Plan if the Company determines that Participant has violated the Company's Anti-Kickback Statute Policies & Procedures.

(m) A Participant may not assign or otherwise transfer Participant's rights, obligations, or duties contained in this Plan.

SECTION 409A

7

(a) To the fullest extent possible, amounts and other benefits payable under the Plan are intended to be comply with or be exempt from Code Section 409A, and the Company shall have complete discretion to interpret and construe this Agreement and any associated documents in any manner that establishes an exemption from (or compliance with) the requirements of Code Section 409A.  Any terms of this Plan that are undefined or ambiguous shall be interpreted by the Company in its discretion in a manner that complies with Code Section 409A to the extent necessary to comply with Code Section 409A. If for any reason, such as imprecision in drafting, any provision of this Plan does not accurately reflect its intended establishment of an exemption from (or compliance with) Code Section 409A, as demonstrated by consistent interpretations or other evidence of intent, such provision shall be considered ambiguous as to its exemption from (or compliance with) Code Section 409A and shall be interpreted by the Company in a manner consistent with such intent, as determined in the discretion of the Company. If, notwithstanding the foregoing provisions of this paragraph, any provision of this Plan would cause a Participant to incur any additional tax or interest under Code Section 409A, the Company shall interpret or reform such provision in a manner intended to avoid the incurrence by the Participant of any such additional tax or interest; provided that the Company agrees to maintain, to the maximum extent practicable, the original intent and economic benefit to the Participant of the applicable provision without violating the provisions of Code Section 409A.

(b) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Plan providing for the payment of any amounts or benefits that the Company determines may be considered nonqualified deferred compensation under Code Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A, and, for purposes of any such provision of this Plan, references to a “termination,” “termination of employment” or like terms shall mean such a separation from service. The determination of whether and when a separation from service has occurred for purposes of this Plan shall be made in accordance with the presumptions set forth in Section 1.409A-1(h) of the Treasury Regulations.

(c) Any provision of this Plan to the contrary notwithstanding, if at the time of a Participant's separation from service, the Company determines that the Participant is a “specified employee,” within the meaning of Code Section 409A, based on an identification date of December 31, then to the extent any payment or benefit that the Participant becomes entitled to under this Plan on account of such separation from service would be considered nonqualified deferred compensation under Code Section 409A, such payment or benefit shall be paid or provided at the date which is the earlier of (i) six (6) months and one day after such separation from service, and (ii) the date of the Participant's death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this paragraph shall be paid or provided to the Participant in a lump-sum and any remaining payments and benefits due under this Plan shall be paid or provided in accordance with the normal payment dates specified for them herein.

(d) Any reimbursements and in-kind benefits provided under this Plan that constitute deferred compensation within the meaning of Code Section 409A shall be made or provided in accordance with the requirements of Code Section 409A, including, without limitation, that (i) in no event shall any fees, expenses or other amounts eligible to be reimbursed by the Company under this Plan be paid later than the last day of the calendar year next following the calendar year in which the applicable fees, expenses or other amounts were incurred; (ii) the amount of expenses eligible for reimbursement, or in-kind benefits that the Company is obligated to pay or provide, in any given calendar year shall not affect the expenses that the Company is obligated to reimburse, or the

8

in-kind benefits that the Company is obligated to pay or provide, in any other calendar year, provided that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement is in effect; (iii) the Participant'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 Participant's remaining lifetime (or if longer, through the sixth (6th) anniversary of the commencement date of such obligations).

(e) For purposes of Code Section 409A, the Participant's right to receive the Change-in-Control payments shall be treated as a right to receive a series of separate and distinct payments.  Whenever a payment under this Plan specifies a payment period with reference to a number of days (for example, “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company. In no event may the Participant, directly or indirectly, designate the calendar year of any payment to be made under this Plan, to the extent such payment is subject to Code Section 409A.

(f) The Company makes no representation or warranty and shall have no liability to the Participant or any other person if any provisions of this Plan are determined to constitute deferred compensation subject to Code Section 409A but do not satisfy an exemption from, or the conditions of, Code Section 409A.

AMENDMENT AND TERMINATION OF PLAN

The Company reserves the right to modify or terminate this Plan with respect to one or more Participants (or all Participants) at its sole discretion at any time. However, any such modification or termination will not impact Participants who have already had a Qualifying Change-in-Control Termination as of the date of the modification or termination. In addition, any Participant impacted by any such modification or termination will be notified by the Company thirty (30) days prior to implementation of such modification or termination. Following a Change in Control (as defined below), the Plan may not be terminated or adversely amended with respect to anyone who is a Participant on the date of the Change in Control without the consent of such Participant.

DEFINITIONS

For purposes of this Plan, the following definitions will be used:

1. "Participant” means any Executive Officer of the Company or other senior executive that has been selected as described above under “Participation” and, in each case, who executes an Acknowledgement Form.

2."Cause”will mean any of the following:

a. Conduct which is materially detrimental to the Company's reputation, goodwill or business operations;

b. Gross or habitual neglect of Participant's duties or obligations or breach of such duties,

9

or misconduct in discharging such duties;

c. Participant's failure to substantially perform his or her duties to the Company or the repeated absence from his or her duties without the consent of the Chief Executive Officer of the Company;

In no event shall a Participant be considered to have been terminated for “Cause” unless the Company delivers a written notice of termination to the Participant identifying in reasonable detail the acts or omissions constituting “Cause” and the provision of this Plan relied upon. In the case where such acts or omissions are not capable of cure, the Participant's termination will take effect upon his or her receipt of such notice. In the case where such acts or omissions are capable of cure, the Participant's termination will take effect fifteen (15) days following his or her receipt of such notice if such acts or omissions are not cured by the Participant by such date, provided the Company may suspend the Participant's employment or place him or her on leave of absence pending such cure. For the avoidance of doubt, mere failure of the Company to achieve earnings goals shall not constitute “Cause.”

To qualify for the other benefits under the Plan upon voluntary termination for Good Reason, a Participant must notify the Company in writing of termination for Good Reason specifying the event constituting Good Reason within thirty (30) calendar days of the Participant being notified of the event. Failure for any reason to give written notice of termination of employment for Good Reason shall be deemed a waiver of the right to voluntarily terminate employment and claim Good Reason under this Plan in relation to such event. The Company shall have a period of thirty (30) days in which to cure the Good Reason. If the Good Reason is cured within this period, a

10

Participant will not be entitled to voluntarily terminate for Good Reason with respect to the event that has been cured.

5. “Disability" will mean the Participant is unable to perform his or her duties to the Company or its subsidiaries by reason of illness or other physical or mental disability, and such physical or mental disability has continued for 90 days or would be reasonably expected to continue for at least 90 days.
