Subject: Deferral of Term Loan Principal Payments

Dear Lloyd,

Pursuant to our discussions, I am requesting that Laurus agree to reduce the
monthly principal payments due under our Secured Non-Convertible Term Note dated
as of June 30, 2006 for the period of July 2007 to September 2008 to $100,000
per month. The resulting $1,500,000 of deferred principal payments will be added
to our last payment due in June 2009. Please also confirm no further
documentation is required to evidence this agreement.

Please let me know of any questions. If you are in agreement with our request,
please note your agreement below and return an executed copy to my attention via
email. Thank you again for your continued cooperation.

Sincerely,

/s/ Charles E. Coppa
