If at any time the Company elects or is required to purchase any Units pursuant to Section 4, the Company shall pay the purchase price for the Units it purchases (i) first, by the cancellation of any indebtedness, if any, owing from the Executive to the Company or any of its subsidiaries (which indebtedness shall be applied pro rata against the proceeds receivable by each member of the Executive Group receiving consideration in such repurchase) and (ii) then, by the Company’s delivery of a check or wire transfer of immediately available funds for the remainder of the purchase price, if any, against delivery of the certificates or other instruments representing the Units so purchased, duly endorsed; provided that if any of the conditions set forth in Section 5.1(a) exists which prohibits such cash payment (either directly or indirectly as a result of the prohibition of a related cash dividend or distribution), the portion of the cash payment so prohibited may be made, to the extent such payment is not prohibited, by the Company’s delivery of a junior subordinated promissory note (which shall be subordinated and subject in right of payment to the prior payment of any debt outstanding under the Financing Agreements and any modifications, renewals, extensions, replacements and refunding of all such indebtedness) of the Company (a “Junior Subordinated Note”) in a principal amount equal to the balance of the purchase price, payable (x) in the event of a termination of employment referenced in Section 4.2(a)(i) and (ii), as soon as the conditions set forth in Section 5.1(a) no longer exist or (x) in the event of a termination of employment referenced in Section 4.2(a)(iii), on the fifth anniversary of the issuance thereof, and bearing interest payable annually at the Applicable Federal Rate on the date of issuance; provided further that if any of the conditions set forth in Section 5.1(a) exists which prohibits such payment (or the payment described in the next proviso) by delivery of a Junior Subordinated Note, the portion of the payment so prohibited may be made, to the extent such payment is not prohibited, by the Company’s delivery of preferred units of the Company having an aggregate liquidation preference equal to the balance of the purchase price; provided further that in the case of a purchase pursuant to Section 4.2(a)(iii) the Company may elect at any time to deliver a Junior Subordinated Note in a principal amount equal to all or a portion of the cash purchase price (in lieu of paying such portion of the purchase price in cash), which Junior Subordinated Note shall mature on the fifth anniversary of its issuance and accrue interest annually at the Applicable Federal Rate on the date of issuance, which interest shall be payable at maturity. The Company shall use its reasonable efforts to repurchase Units pursuant to Section 4.1(a) or Section 4.2(a)(i) or Section 4.2(a)(ii) with cash and/or to prepay any Junior Subordinated Notes or redeem any preferred units issued in connection with a repurchase of Units pursuant to Section 4.1(a) or Section 4.2(a)(i) or Section 4.2(a)(ii). The Company shall have the right set forth in clause (i) of the first sentence of this Section 5.2 whether or not the member of the Executive Group selling such units is an obligor of the Company. Any Junior Subordinated Note (or preferred units issued in lieu thereof) shall become prepayable (or redeemable) upon a Sale of the Company from net cash proceeds, if any, payable to the Company or its unitholders; to the extent that

11

sufficient net cash proceeds are not so payable, the Junior Subordinated Note (or preferred units issued in lieu thereof) shall be cancelled in exchange for such other non-cash consideration received by unitholders in the Sale of the Company having a fair market value equal to the principal of and accrued interest on the note. 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 ▇▇▇▇▇▇ care, other ▇▇▇▇▇▇ 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.

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.

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.

13

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.
