case of any conflict with this Agreement.

         3. Expiration of the Option. The Option (to the extent not earlier
exercised or terminated due to cessation of the Optionee's employment or
otherwise in accordance with the Plan) will expire at the end of business on
March 30, 2008. The Option may terminate sooner under certain circumstances,
including, without limitation, termination of the Optionee's employment or a
change in control of the Company, as set forth in Sections 5.13, 7.1, and 7.2 of
the Plan. The Option may not be exercised after its expiration or termination.

         4. Exercise Plan. The "Exercise Price" of the Option is $9.42 per share
of Common Stock. The Exercise Price is subject to adjustment as set forth in
Article III of the Plan.

         5. Vesting. On each Measurement Date set forth in Column 1 below, the
Option shall vest and become exercisable for the corresponding number of shares
of Common Stock set forth in Column 2 below if the Optionee's employment has not
terminated. The "Vested Portion" of the Option as of any particular date shall
be the cumulative total of all shares for which the Option has become

of the Option, except that no Option shall be exercisable except in respect to

the Plan administrator may deem acceptable.

         8. Nontransferability of Option. The Option shall not be transferable
or assignable by the Optionee, other than in accordance with Section 5.9 of the
Plan or by will or the laws of descent and distribution (or as otherwise
permitted by the Plan administrator in its sole discretion), and shall be
exercisable during the Optionee's lifetime only by him or her or by his or her
legal representative(s) or guardian(s).

         9. Administration. The Plan and this Agreement shall be administered
