                          options you have received from your previous employer
                          (i.e., the difference between the "strike price" of
                          any such options and the price at which such shares
                          close on the date exercised or the actual selling
                          price on that date). You will provide the necessary
                          documentation to establish the amount of such realized

                          (the "Net Signing Bonus"). The Net Signing Bonus will
                          be paid as follows:

                          50% on the later of 30 days after the employment start
                          date or 7 days after the Net Signing Bonus is

                          25% on the first anniversary of your employment start

                          date.

                          In the event that you resign without Good Reason or
                          are terminated for cause within one (1) year after
                          your employment start date, you agree to return to GCL
                          the first payment of the Signing Bonus, prorated on a
