COMMON  STOCK  OF  CDEX-Inc.


Loch Harris, Inc., a Nevada corporation (Loch), as owner of the shares described
above, appoints the Board of Directors of CDEX-Inc., a Nevada corporation (CDEX)
as Loch's proxy to act for and on behalf of Loch to attend shareholders'
meetings, vote, execute consents and otherwise act for Loch in connection with
such shares in the same manner and with the same effect as if Loch were
personally present. It is agreed that the authority and rights given to the
Board of Directors of CDEX by Loch with respect to this proxy were given for
good and valuable consideration (the sufficiency of which is mutually
recognized) and are irrevocable except as to the termination provisions
contained in the following paragraph. In addition, it is agreed that the Board
of Directors of CDEX is to vote the shares of this proxy in accordance with the
best interest of CDEX. It is the intent of both parties that this proxy is in
itself a complete and irrevocable transfer of all voting rights of these shares
to the Board of Directors of CDEX until the termination provisions of the
following paragraph take effect. The Board of Directors of CDEX accepts such
appointment.

This proxy shall terminate immediately and automatically as to any shares
covered by this proxy when, as and if any such shares are sold, transferred or
assigned to any party not under the control of Loch or its officers or
directors. No further action shall be necessary to affect such revocation;
however, CDEX and its Board of Directors shall execute any such documents that
may be reasonably requested from time to time by Loch or Loch's transferee(s) to
memorialize such revocation as to such shares.
