          Technitrol,  Inc.'s wholly-owned subsidiary,  Pulse Engineering,  Inc.

wholly-owned  subsidiary of Pulse (the "Merger Sub"),  dated as of May 23, 2001.
Pursuant  to the  Merger  Agreement,  Merger  Sub shall be merged  with and into

Merger  is  subject  to  various  conditions,  including,  among  other  things,
