Company and Mr. Gregoire, he is to be employed for a term beginning on January
24, 2005 and expiring on December 31, 2005, with automatic twelve-month renewals
unless notice of non-renewal is provided by either party at least six months
before the scheduled expiration date of the then current term. Any such notice
of non-renewal by the Company will be deemed a termination without cause under
the Employment Agreement. Mr. Gregoire's current annual base salary under the
Employment Agreement is $325,000 subject to annual discretionary increases, if
any, as determined at least annually, by the Board of Directors or a committee

The Company also agreed that Mr. Gregoire will receive options pursuant to the
Company's existing stock option plan, vesting in three equal annual
installments, to purchase 50,000 shares of the Company's Ordinary Common Stock.

If Mr. Gregoire's employment is terminated without cause or if Mr. Gregoire
terminates his employment for good reason, in each case, as defined in the
employment agreement, the Company will make a lump sum payment to Mr.
Gregroire's equal to his then annual base salary plus his target bonus in
addition to payment to Mr. Gregoire of amounts previously earned and, under
certain conditions, a ratable portion of his target bonus.

The foregoing description is qualified in its entirety by reference to the
