Each BWI Option held by a PHC employee which is exercisable on and not exercised prior to the Distribution Date and with respect to which the holder has not elected prior to the Distribution Date to surrender in exchange for an option under the PHC Stock Option Plan ("Priority Option") shall remain outstanding and shall be exercisable only within a period of three months after the Distribution Date according to its terms and the terms of the BWI Stock Option Plan. The number of shares of BWI Common Stock subject to, and the exercise price of such BWI Option after the Distribution Date shall be determined in accordance with the requirements of Section 424 of the Code and the regulations promulgated thereunder. The exercise price of any such BWI Option shall be rounded to the nearest $.01; the number of shares subject to any such BWI Option shall be rounded to the nearest whole share; the aggregate Spread of such BWI Option immediately after the Distribution Date shall be equal to the Spread of such BWI Option immediately before the Distribution Date. "Spread" means, as of the same date, the excess of the fair market value of the shares subject to the option over the aggregate option price. (b) BWI and PHC shall cooperate and take all action necessary so that as of the Distribution Date, each BWI Option held by a PHC employee and which is either (i) exercisable on, and not exercised on or prior to, the Distribution Date, or (ii) not exercisable on or prior to the Distribution Date, and with respect to which the holder has elected prior to the Distribution Date to surrender in exchange for a Priority Option, shall both, without any action on the part of the holder thereof, be considered to be surrendered to BWI in exchange for a Priority Option. The number of shares of PHC Class B Common Stock subject to and the exercise price of such Priority Option shall be determined in accordance with the requirements of Section 424 of the Code and the regulations promulgated thereunder. The exercise price of any such Priority Option shall be rounded to the nearest $.01; the number of shares subject to any such option shall be rounded to the nearest whole share; the aggregate Spread of such Priority Option immediately after the Distribution Date shall be equal to the Spread of the BWI Option surrendered for it immediately before the Distribution Date; and such Priority Option shall be granted under the PHC Stock Option Plan with an outstanding exercise period and vesting schedule which is the same as the exercise period and vesting schedule of the BWI Option surrendered for it. Section 2.9. PROFIT SHARING PLANS. (a) After the Distribution Date, employees of PHC will no longer be eligible to participate in the qualified profit sharing plan maintained by BWI ("BWI Profit Sharing Plan"). On or before the Distribution Date, PHC shall establish a similar profit sharing plan ("PHC Profit Sharing Plan"), including a 401(k) feature and a PHC Common Stock Fund, in lieu of a BWI Common Stock Fund. The PHC Profit Sharing Plan shall also provide for a BWI Common Stock Fund into which any BWI Common Stock held by PHC employees under the BWI Profit Sharing Plan shall be transferred, but no further investments in BWI Common Stock may be made under the PHC Profit Sharing Plan. (b) BWI shall also amend the BWI Profit Sharing Plan before the Distribution Date to provide for a PHC Common Stock Fund into which the PHC Class A Common Stock received as a distribution from BWI on the BWI Common Stock held by the BWI Profit Sharing Plan shall be placed. No further investments in PHC Common Stock may be made by participants in the BWI Profit Sharing Plan. (c) On or promptly after the Distribution Date, all assets in the BWI Profit Sharing Plan relating to PHC employees shall be transferred to the PHC Profit Sharing Plan and BWI and the BWI Profit Sharing Plan shall have no further obligations or liabilities to such PHC employees. Section 2.10. TAX COVENANTS. After the Distribution Date neither BWI or any member of the BWI Group nor PHC or any member of the PHC Group, shall take any action, or permit any action to be taken, which could reasonably be expected to prevent the Distribution from qualifying as a tax-free distribution under Section 355 of the Code. ARTICLE III ASSUMPTION, INDEMNITY AND RELEASE Section 3.1. INDEMNITIES. (a) COMPREHENSIVE OBLIGATIONS, CLAIMS AND LIABILITIES. PHC, on its behalf and on behalf of the PHC Group, does hereby assume and agree to pay, perform and discharge all obligations, liabilities and Losses in any way arising out of or relating to the PHC Business (whether known or unknown, absolute, contingent or otherwise, matured or not matured, accrued or unaccrued, of whatever nature and whenever arising and regardless of when discovered, and including contingent liabilities and obligations as have accrued or will accrue to the BWI Group relating to the past, present or future PHC Business), or to acts or events occurring or conditions existing with respect to the PHC Business, whether before, on or after the Distribution Date, including without limitation (a) all contracts, agreements, commitments, undertakings, notes, letters of credit, bonds, guarantees, warranties, indemnities, accounts payable, purchase orders, leases, licenses, liens, mortgages, restrictions and covenants, (b) all employee or employment related obligations and liabilities, (c) all environmental conditions and responsibilities (including without limitation hazardous and toxic waste and material), and (d) all Actions, including those relating to damage or injury to person, property, business or reputation (all of the foregoing collectively the "Assumed Liabilities"); PROVIDED, HOWEVER, that the Assumed Liabilities do not include the obligations of BWI pursuant, and subject to the provisions of, the Ancillary Agreements.
