B. The Employer desires to amend the Hours of Service requirement for eligibility to participate in the Plan to be consistent with the collective bargaining agreement between Allegiance Healthcare Corporation - Hayward, California and ILWU Local 6, effective as of January 1, 2001 (the "Bargaining Agreement"). C. The Employer also desires to amend the profit sharing contribution allocation computation period for Fixed Contributions and Transition Contributions to the Plan Year, effective as of July 1, 2001, and to authorize an allocation of such contributions for a short Contribution Allocation Period of January 1, 2001 to June 30, 2001. D. Section 12.1 of the Basic Plan Document permits the amendment of the Plan by action of the Employer at any time. AMENDMENT --------- 1.

Sections II.B.2. and II.I. of the Adoption Agreement are also hereby amended to provide that 800 Hours of Service must be completed to participate in the Plan, as required by the Bargaining Agreement, and to permit participation to commence immediately upon meeting such requirement by revising the definition of "Entry Date" accordingly. 2. Effective July 1, 2001, Sections V.C.1. and 2. of the Adoption Agreement are hereby amended to change the profit sharing contribution allocation computation period for Fixed Contributions and Transition Contributions to the Plan Year, rather than the calendar year, and Section V.C.4. is amended to reflect the short Plan Year allocation resulting from this change. 3.
