cancelled in such Maturity Netting shall be automatically cancelled as of the
date of such Maturity Netting and, thereafter, this Note shall be deemed to be
paid in full and shall be null and void.  The Maturity Netting shall
automatically occur on the Maturity Date (as defined in the Series B Note).

written notice to the Company, Net all, or any part, of the outstanding
obligations under the Series B Note by the cancellation of such portion of the
outstanding obligations under the Series B Note as set forth in such written
notice in exchange for the surrender and concurrent cancellation of an equal
amount of Principal hereunder (each, an “Event of Default Netting”).  Upon any
Event of Default Netting, any accrued and unpaid Interest hereunder with respect
to such portion of Principal being satisfied in such Event of Default Netting

collectively, the “Investor Netting Rights”).  Upon any Bankruptcy Event of
Default Netting, any accrued and unpaid Interest hereunder with respect to such
portion of Principal being satisfied in such Bankruptcy Event of Default Netting
shall be automatically cancelled as of the date of such Bankruptcy Event of
Default Netting and, thereafter, this Note shall be deemed to be paid in full
and shall be null and void.  Each Bankruptcy Event of Default Netting shall be
effective upon the date of the earliest occurrence of a Bankruptcy Event (as
defined in the Series B Note) under the Series B Note.

outstanding obligations under the Series B Note equal to 75% of the remaining
Restricted Principal then outstanding under the Series B Note (with the
remaining 25% of the Restricted Principal of the Series B Note automatically
becoming unrestricted principal thereunder) in exchange for the surrender and
concurrent cancellation of the aggregate Principal then outstanding hereunder.
 Upon any Prohibited Transfer, any accrued and unpaid Interest hereunder shall
be automatically cancelled as of the date of such Prohibited Transfer and,
thereafter, this Note shall be deemed to be paid in full and shall be null and
