RECITALS

A. Executive and the Company entered into that certain Employment Agreement
dated as of March 29, 2011 (the “Agreement”).

B. Executive and the Company desire to modify the Agreement pursuant to the
terms of this Amendment.

In consideration of the mutual covenants contained herein and other good and

1. Defined Terms. All capitalized terms not defined in this Amendment shall have
the meanings given to such terms in the Agreement.

2. Non-Compete; Non-Solicit. Sections 7(a) and 7(b) of the Agreement are hereby

the Subsidiaries’ trade secrets and with other Confidential Information

in, manage, control, participate in, consult with, render services for, or in

render services specifically with respect to any unit, division, segment or
subsidiary of any other business that engages in or otherwise competes with (or
was organized for the purpose of engaging in or competing with) the business of
providing behavioral healthcare and/or related services (provided that, this
clause (ii) shall not be construed to prohibit Executive from directly or
indirectly owning any interest in, managing, controlling, participating in,
consulting with, rendering services for, or in any manner engaging in any
business activities with or for such business generally and, for the avoidance
of doubt, not specifically with respect to such unit, division, segment or
subsidiary), in

business entity (whether as a director, officer, manager, supervisor, employee,
agent, consultant or otherwise). Nothing herein shall prohibit Executive from
being a passive owner of not more than 2% of the outstanding stock of any class
of a corporation which is publicly traded, so long as Executive has no active
participation in the business of such corporation; and

 

  (ii) during the Employment Period and for a period thereafter of twelve
(12) months, Executive shall not shall not directly or indirectly own any
interest in, manage, control, participate in, consult with, render services for,
or in any manner engage in any business with, for or on behalf of Behavioral

not be subject to the restrictions set forth in this Section 7(a)(ii) if the
Employment Period is terminated by the Company without Cause or by Executive
with Good Reason and for so long as the Company is in breach of its obligations
under Section 4(b) and such breach is not the subject of a good faith dispute
between the Company and Executive.

 

  (b) Non-Solicit. During the Employment Period and for a period thereafter of
twelve (12) months (the “Nonsolicit Period”), Executive shall not directly or
indirectly through another Person (other than on behalf of Holdings and the
Subsidiaries) (i) induce or attempt to induce any employee or independent
contractor of Holdings or the Subsidiaries to leave the employ or services of
Holdings or the Subsidiaries, or in any way interfere with the relationship
between Holdings and the Subsidiaries and any employee or independent contractor
thereof, (ii) hire or seek any business affiliation with any person who was an
employee or independent contractor of Holdings or the Subsidiaries at any time
during the twelve (12) months prior to the Termination Date or (iii) induce or
attempt to induce any customer, supplier, licensee, licensor or other business
relation of Holdings or any Subsidiary to cease doing business with Holdings or
such Subsidiary; provided that Executive shall not be subject to the
restrictions set forth in this Section 7(b) if the Employment Period is

such breach is not the subject of a good faith dispute between the Company and
