IL Aerospace Technologies (ILAT) was the sole Israeli entrant to the Ansari X-prize competition.
Their initial X-prize entry was the Negev-5 (Negevs 1 through 4 being various planned subscale/prototypes). Like the da Vinci Project entry, the first 'stage' was a balloon that lifted the hybrid rocket power capsule to altitude.
The first attached PDF from January 2003, from the original X-prize website page at http://space.xprize.org/ansari-x-prize/il-aerospace-technologies, gives various team and vehicle information. The subsequent attached pictures also come from the PDF. The second attached PDF, from July 2003, is a fairly minor update to the original - with a different capsule picture (also attached). The vehicle and mission details from this second PDF are:
