Separation package:

In addition, if within the first year of your employment, SiteSmith hires a new
CEO and your position is materially changed (i.e. reduction of position, salary,
significant change in job location), this change will be construed as a
constructive termination and you will be given a separation package to consist
of the following:

                                                    6 (six) months base salary
                                                     continuation
                                                    6 (six month acceleration of
                                                     vesting with a minimum
                                                     guarantee of 1 (one) year
                                                     total vesting (including
                                                     current vested amount)

In regards to the acceleration of vesting, stock options will be provided in the
event of a "change of control." The acceleration will only happen if both a
change of control and constructive termination has occurred. The acceleration
will be for half of whatever options are not currently vested.

In addition, you will be given the opportunity to exercise in advance your stock
options with the provision that the company has the right to repurchase shares
at the exercise price for shares that would be unvested in a normal 4 year
vesting schedule.

You will also be eligible for coverage under the SiteSmith, Inc., Medical and
Dental plans and Life Insurance plan. Descriptions of these plans will be
provided when you report for work.

Enclosed is our company's Confidentiality Agreement and Invention Assignment

you will be asked to sign each Agreement as a condition of employment.

Your employment is contingent on your providing us with evidence that you have a
legal right to work in the United States pursuant to provisions of the
