Advanced Technologies, Inc. ("Orbit").  Orbit has been responsible for operating
the antennae measurement unit for Alchut and its subsidiaries and possesses the
technical know-how necessary for the operation of the antennae measurement unit.
Orbit has maintained an antennae measurement unit in Israel, the employees of
which, although employed by Alchut, worked under the supervision of Orbit. In
contemplation of an initial public offering by Orbit/FR, it became necessary for
Alchut to transfer the antennae measurement unit in Israel to Orbit/FR.

establishing its antennae measurement unit as a separate entity.  Effective at
11:58 p.m. on December 31, 1996, Alchut and Engineering entered into an Asset
Acquisition Agreement.   In addition, the personnel formerly employed in the
antennae measurement unit were transferred to Engineering.  In accordance with
the foregoing, the parties desire that Alchut now sell, convey and transfer, and
Engineering buy and acquire the inventory of the commercial and engineering
portions, but not the production portion, of the antennae measurement unit in
Israel (the "Business"), subject to the terms and conditions stated in this
Agreement.
