March 29, 2002  ARTICLE I ESTABLISHMENT AND PURPOSE OF THE PROGRAM   1.01        Establishment of Program  The 1999 Non-Employee Director Option Program (the Program) is

Plan) and, in addition to the terms and conditions set forth below, is
subject to the provisions of the Plan.  1.02        Purpose of Program  The purpose of the Program is to enhance the ability of the Company to
attract and retain directors who are not Employees (Non-Employee Directors)
through a program of automatic Option grants.  1.03        Effective Date of the Program  The Program became effective as of the Registration Date on December 1,
1999, and was first amended and restated by the Board on April 22, 2001 to
increase the number of Shares granted pursuant to Initial Grants and Subsequent
Grants (as defined below) and to change the vesting provisions thereunder.   The Program was further amended and
restated by the Board on March 29, 2002 to increase the number of Shares
granted pursuant to Initial Grants and Subsequent Grants, to award additional
Option grants to Non-Employee Directors serving on committees of the Board, and
to change the vesting provisions for all automatic Option grants.   ARTICLE II DEFINITIONS   Capitalized terms in this Program, unless otherwise defined in this
