employment agreement; or (iv) a change of your principal place of employment to
a location more than seventy-five (75) miles from such principal place of

creditor of the Company. Nothing in this Retention Agreement is intended to
suggest any guaranteed period of continued employment and your employment will
at all times continue to be terminable by you or the Company. This Retention
Agreement will be binding on any successor to the Company. This Retention
Agreement will be governed by, and construed in accordance with, the laws of the
State of Delaware.
