    PORTACOM ANNOUNCES CLOSING OF SALE OF EQUITY STAKE IN METROMEDIA CHINA
                     CORPORATION TO VDC CORPORATION, LTD.

     PortaCom Wireless, Inc. ("PortaCom") announced today that it has completed
the sale to VDC Corporation, Ltd. (OTCBB: VDCLF) ("VDC") of its 2,000,000 shares
and warrants to acquire, at $4 per share, an additional 4,000,000 shares of
Metromedia China Corporation (formerly Metromedia Asia Corporation).   In
consideration for the sale and subject to certain adjustment features, PortaCom
received a pool of up to 5,300,000 shares of VDC common stock and a maximum of
$3,000,000 in cash.  To the extent that more than $384,725 of the cash is used
by PortaCom, the excess thereof will result in PortaCom returning to VDC a
certain number of shares of VDC common stock according to a predetermined
formula. The final amounts of the cash and VDC common stock received will be
determined by PortaCom, its creditors and the United States Bankruptcy Court for
the District of Delaware (the "Bankruptcy Court").

     The combined cash and share components of the sale proceeds will be used to
fund PortaCom's plan of reorganization, which has been filed with the Bankruptcy
Court but remains subject to, among other things, the approval of impaired
creditors and stockholders under the United States Bankruptcy Code and
confirmation by the Bankruptcy Court.

     Based on information provided by VDC, VDC is a development stage company
that intends to pursue opportunities to establish wireless, wired and cellular
telephony systems, operate international telephony gateways and become internet
service providers in certain areas of Eastern Europe and Asia, as well as Egypt
and the United States.  VDC recently announced that it has entered into
agreements with Egypt's National Telecom Company to establish, and actively
manage, 50% owned Egyptian corporations whose purpose will be to provide
telecommunications and internet services in Egypt as well as billing services
for telecommunications and utility businesses in Egypt, the Middle East, and
Africa.

 
     VDC also manages and/or acts as agent for existing communications tower and
building top sites and markets the sites to communications companies, such as
wireless telephony, paging and cable television service providers, who require
the use of such sites for their communications transmitter and receiver
infrastructure.
