options held by Mr. Rudolph and the acceleration of the vesting of a portion of
other stock options held by him.&#160; The

On Assignment is the surviving entity, but in which 50% or more of On
Assignment&#146;s outstanding voting stock is transferred to holders different from
those who held the stock immediately prior to such merger; (d) the acquisition

(c)&nbsp;his resignation following a reduction in his base salary or target
bonus or a material reduction in his benefits, or (d)&nbsp;his resignation
following a change in his position with the company that materially reduces his
level of responsibility or authority.&#160;
The executive&#146;s resignation</font> for any reason or for no reason
during the period commencing on the date that is six months after the date of a
Change of Control and ending ten business days thereafter also would be deemed
