ITEM 1.01  ENTRY INTO MATERIAL DEFINITIVE AGREEMENT

On March 29, 2005, our Compensation Committee approved an increase in the annual
salary of Mr. Carl Gruenler, our Vice President of Government and Force
Protection Systems Group, from $185,000 to $250,000, effective April 1, 2005.
This increase reflects an amendment to the letter agreement dated July 30, 2003
under which Mr. Gruenler is employed. The letter agreement also provides for an
annual performance bonus of up to 10% of base salary to be determined by the
Compensation Committee and the Board of Directors. Mr. Gruenler is now
compensated through a broad-based commission arrangement in lieu of an annual
performance bonus. Under this arrangement, commissions are awarded for each of
our business segments based on achievement of operating plan revenue within the
segment, with commissions increasing in percentage if operating plan is
exceeded. Executive officers in charge of each business unit recommend an
allocation of such commissions amongst sales personnel and themselves, which
recommendation is reviewed and approved by the Chairman and the President. All
commissions payable to executive officers are then reviewed and approved by the
Compensation Committee.

Mr. Gruenler's employment is terminable at-will by us or by Mr. Gruenler for any
reason, with or without notice.
