Any Junior Subordinated Note (or preferred units issued in lieu thereof) also shall become prepayable upon the consummation of an initial Public Offering. The principal of and accrued interest on any such note may be prepaid (and preferred units issued in lieu thereof may be redeemed) in whole or in part at any time at the option of the Company. If interest (or cash dividends) is required to be paid on any Junior Subordinated Note (or preferred units issued in lieu thereof) prior to maturity and any of the conditions set forth in Section 5.1(a) exists or if any such cash payment would result in adverse accounting treatment for the Company which prohibits the payment of such interest (or dividends) in cash, such interest may be cumulated and accrued until and to the extent that such prohibition no longer exists.

6. Noncompetition.

6.1 Competitive Activity. Executive shall be deemed to have engaged in “Competitive Activity” if, during the period commencing on the date hereof and ending on the later of (x) the first anniversary of the date Executive’s employment with the Company and its subsidiaries is terminated or (y) the maximum number of years of base salary Executive is entitled to receive as severance in a termination by the Company without Cause, Executive, whether on Executive’s own behalf or on behalf of or in conjunction with any other person or entity, directly or indirectly (A) solicits, or assists in soliciting, the business of any client of the Company or any of its subsidiaries (collectively, the “Entities”), or hires any employee of any of the Entities, or interferes with, or attempts to interfere with, the relationships between any of the Entities, on the one hand, and any of its customers, clients, suppliers, partners, members, employees or investors, on the other hand; or (B) becomes an employee, agent, representative, consultant, partner, shareholder or holder of any other financial interest with respect to any business, individual, partnership, joint venture, association, firm, corporation or other entity engaged, wholly or in part, in the provision or sale of acquired brain injury services, therapeutic xxxxxx care, other xxxxxx care or other home or community-based healthcare, therapy, counseling or other educational or human services to people with special needs, or any other business that the Company is actively conducting or is actively considering conducting at the time of Executive’s termination of employment (so long as Executive knows or reasonably should have known about such plan(s)), in each case in any geographical area within 100 mile radius of the Executive’s principal place of work as of the Termination Date with the Company or its affiliates, as applicable(the “Competitive Business”). Notwithstanding the foregoing, if Executive is subject to a more restrictive noncompetition covenant in any agreement with the Company or any of its affiliates, the most restrictive of such noncompetition covenants shall apply.

6.2 Activity Date. If Executive engages in Competitive Activity, the “Activity Date” shall be the first date on which Executive engages in such Competitive Activity.

6.3 Repayment of Proceeds. If Executive engages in Competitive Activity, then Executive shall be required to pay to the Company, within ten business days following the Activity Date, an amount equal to the excess, if any, of (A) the aggregate proceeds Executive

received upon the sale or other disposition of Executive’s Units, over (B) the aggregate Cost of such Units.

7. Miscellaneous.

7.1 Transfers to Permitted Transferees. Prior to the transfer of Units to a Permitted Transferee (other than a transfer subsequent to a Sale of the Company), the Executive shall deliver to the Company a written agreement of the proposed transferee (a) evidencing such Person’s undertaking to be bound by the terms of this Agreement and (b) acknowledging that the Units transferred to such Person will continue to be Units for purposes of this Agreement in the hands of such Person. Any transfer or attempted transfer of Units in violation of any provision of this Agreement or the Securityholders Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Units as the owner of such Units for any purpose.

7.2 Recapitalizations, Exchanges, Etc., Affecting Units. The provisions of this Agreement shall apply, to the full extent set forth herein with respect to Units, to any and all securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for, or in substitution of the Units, by reason of any dividend payable in units, issuance of units, combination, recapitalization, reclassification, merger, consolidation or otherwise.

7.3 Executive’s Employment by the Company. Nothing contained in this Agreement shall be deemed to obligate the Company or any subsidiary of the Company to employ the Executive in any capacity whatsoever or to prohibit or restrict the Company (or any such subsidiary) from terminating the employment of the Executive at any time or for any reason whatsoever, with or without Cause.

7.4 Cooperation. Executive agrees to cooperate with the Company in taking action reasonably necessary to consummate the transactions contemplated by this Agreement.

7.5 Binding Effect. The provisions of this Agreement shall be binding upon and accrue to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns; provided, however, that no Transferee shall derive any rights under this Agreement unless and until such Transferee has executed and delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement; and provided further that Vestar is a third party beneficiary of this Agreement and shall have the right to enforce the provisions hereof.

7.6 Amendment; Waiver. This Agreement may be amended only by a written instrument signed by the parties hereto. No waiver by any party hereto of any of the provisions hereof shall be effective unless set forth in a writing executed by the party so waiving.

7.8 Jurisdiction. Any suit, action or proceeding with respect to this Agreement, or any judgment entered by any court in respect of any thereof, shall be brought in any court of competent jurisdiction in the State of Delaware, and each of the Company and the members of the Executive Group hereby submits to the exclusive jurisdiction of such courts for the purpose of any such suit, action, proceeding or judgment. Each of the members of the Executive Group and the Company hereby irrevocably waives (i) any objections which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement brought in any court of competent jurisdiction in the State of Delaware, (ii) any claim that any such suit, action or proceeding brought in any such court has been brought in any inconvenient forum and (iii) any right to a jury trial.

7.9 Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given when personally delivered, telecopied (with confirmation of receipt), one day after deposit with a reputable overnight delivery service (charges prepaid) and three days after deposit in the U.S. Mail (postage prepaid and return receipt requested) to the address set forth below or such other address as the recipient party has previously delivered notice to the sending party.
