of Directors of the Company immediately prior to such Merger.

is terminated by the Company or a successor to the Company other than for
Cause (as defined below), or (ii) Employee's job duties, responsibilities and
requirements are materially reduced or changed such that they are
inconsistent with Employee's prior duties, responsibilities and requirements,

100% of the option that has not yet become exercisable shall become
exercisable on the effective date of such termination, reduction or change.

indirect and whether by purchase, lease, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Agreement and agrees expressly
