Note 1

     As of June 8, 1998, PortaCom Wireless, Inc. (the "Debtor") consummated the
sale to VDC Corporation, Ltd. ("VDC") of 2,000,000 shares of common stock and
warrants to acquire, at an exercise price of $4.00 per share, an additional
4,000,000 shares of common stock of Metromedia China Corporation (formerly
Metromedia Asia Corporation). In consideration for the sale of such assets and
subject to certain adjustment features, the Debtor received a pool of 5,300,000
shares of VDC common stock and the right to utilize a maximum of $3,000,000 in
cash to satisfy claims made against the Debtor in connection with Debtor's Plan
of Reorganization (the "Plan") filed in its Chapter 11 bankruptcy case in the
United States Bankruptcy Court for the District of Delaware (the "Bankruptcy
Court"), Case No. 98-661 (PJW). To the extent that more than $384,725 of the
cash is used by PortaCom to satisfy claims made in connection with the Plan, the
excess thereof will result in the Debtor 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 the
Debtor, its creditors and the Bankruptcy Court. The Plan remains subject to,
among other things, the approval of impaired creditors and stockholders and
confirmation by the Bankruptcy Court.

Generally accepted accounting principles require the Debtor to record its
investment in VDC common stock using the equity method. The use of the equity
method for the purposes of this Monthly Operating Report was not possible
because financial statements of VDC as of June 30, 1998 were not available as of
the date this report was required to be filed with the Bankruptcy Court.
Accordingly, the accounts have not been adjusted to reflect any difference
between the value of the investment in VDC common stock which the Debtor now
holds and the value of the investment in Metromedia China Corporation common
stock which the Debtor held prior to the consummation of the sale to VDC.
