                     IN THE UNITED STATES BANKRUPTCY COURT
                         FOR THE DISTRICT OF DELAWARE

In re:                                 :    Chapter 11
                                       :
PORTACOM WIRELESS, INC.,               :    Case No. 98-661 (PJW)
                                       :
          Debtor.                      :

           MOTION OF DEBTOR (A) TO ESTABLISH BIDDING PROCEDURES AND
             APPROVE A BREAK-UP FEE IN CONNECTION WITH THE SALE OF
            THE DEBTOR'S INTEREST IN CERTAIN PROPERTY OF THE ESTATE
               AND (B) TO APPROVE THE FORM AND MANNER OF NOTICE
               ------------------------------------------------

     PortaCom Wireless, Inc. (the "Debtor"), as debtor in possession, hereby
moves this Court for the entry of an order (a) establishing bidding procedures
and approving a break-up fee in connection with the sale of certain assets of
the Debtor, and (b) approving the form and manner of notice (the "Motion"), and
respectfully states in support thereof as follows:

                                 Background
                                 ----------

      1.  On March 23, 1998 (the "Filing Date"), the Debtor filed a voluntary
petition for reorganization under chapter 11 of title 11 the United States Code
(the "Bankruptcy Code").  Since the Filing Date, the Debtor has continued in
possession of its assets and operation of its business as a debtor-in-possession
pursuant to (S)(S) 1107 and 1108 of the Bankruptcy Code.

      2.  PortaCom Wireless, Inc., a publicly held Delaware corporation,
develops wireless and wireline telecommunications services in selected
developing world markets.

      3.  The Debtor's assets consist primarily of its interest in 2,000,000
shares of common stock (the "MAC Shares") in Metromedia Asia Corporation ("MAC")
and warrants to purchase an additional 4,000,000 shares of MAC common stock with
a strike price of $4.00 per


<PAGE>
 
share (the "Warrants").

      4.  During this Chapter 11 case, the Debtor intends to sell its interest
in the MAC Shares and Warrants pursuant to section 363 of the Bankruptcy Code.
The Debtor believes, based on the current value of shares of common stock of VDC
Corporation, Ltd. ("VDC"), that it will receive approximately $30 million, plus
a deferred payment, in consideration for the sale of the MAC Shares and
Warrants.  The proceeds from the sale of the MAC Shares and Warrants (the "Sale
Proceeds") will be used to maximize value to the Debtor's creditors and equity
security holders and fund the Debtor's plan of reorganization.

      5.  In 1996, the Debtor's business generated revenues of approximately
$1,000,000 from one transaction (a break-up fee from a failed merger).  In 1997,
the Debtor did not generate any revenues.  Due to the lack of capital resources,
the Debtor's business activities have virtually come to a standstill.  At the
same time, the Debtor faced increasing pressure from trade creditors and, in
certain instances, litigation in a variety of locations across the country.

      6.  The Debtor determined that for it to maximize value to its
shareholders and creditors, it was necessary to commence this chapter 11 case
and to sell the MAC Shares and Warrants to the highest bidder pursuant to
sections 363(b) and (f) of the Bankruptcy Code.

      7.  Under the terms of that certain Postpetition Asset Purchase Agreement
between the Debtor and VDC, the Debtor agreed to sell the MAC Shares and
Warrants to VDC in consideration for 5.3 million shares of common stock of VDC
and the difference between $700,000 and the Debtor's outstanding indebtedness
arising from prepetition and postpetition financing 

                                       2
<PAGE>
 
provided by VDC (the "Purchase Offer"), subject to its receipt of higher and
better offers. The proposed sale will generate value to creditors and the
estate, based on the current market value of VDC common stock, of approximately
$30 million, plus a deferred payment. This will, in turn, result in a fund for
distribution under a plan which the Debtor anticipates will be sufficient to
satisfy allowed unsecured claims in full and provide substantial value to the
Debtor's shareholders. A true and correct copy of the Postpetition Asset
Purchase Agreement is attached hereto as Exhibit "A".

                               Relief Requested
                               ----------------

      8.  The Debtor requests the entry of an order establishing bidding
procedures and approving a break-up fee in connection with the sale of the MAC
Shares and Warrants.  The Debtor also seeks approval of the form and manner of
notice of these procedures.  The relief sought is authorized by section 363 of
the Bankruptcy Code and is designed to maximize value to the Debtor's creditors
and equity security holders.  In addition, the Debtor is requesting the Court to
schedule a hearing to consider the Purchase Offer on or about April 15, 1998.
The Debtor submits that a hearing held on that date will not require shortened
notice and is within the time specified for notice under Federal Rule of
Bankruptcy Procedure 2002(a).

                            The Bidding Procedures
                            ----------------------

      9.  Both the Debtor and VDC recognize that the transaction contemplated
by the Postpetition Asset Purchase Agreement will be subject to higher and
better offers. Therefore, the Debtor seeks authority to implement certain
procedures (the "Bidding Procedures") to assure that the Debtor has obtained the
best return possible with respect to the MAC Shares and Warrants for the benefit
of its estate and creditors.

                                       3
<PAGE>
 
      10.  As set forth below, the Debtor will accept bids from interested
third-parties pursuant to the Bidding Procedures.  Bids will be accepted on a
global basis for all of the MAC Shares and Warrants, to the extent that all, or
some portion, of the MAC Shares and Warrants have not been otherwise disposed of
pursuant to an Order of the Bankruptcy Court.  To the extent that third-party
offers are received by the Debtor, the Debtor will conduct an auction between
and among VDC and other parties interested in bidding on the MAC Shares and
Warrants.  The Debtor, pursuant to this Motion, will seek authority to enter
into an agreement with the Successful Bidder (as hereafter defined) for the
purchase and sale of the MAC Shares and Warrants, subject to the approval of
this Court at a duly scheduled hearing (the "Hearing").

                             Notice of the Auction
                             ---------------------

      11.  Within five (5) business days following the entry of an order
granting this Motion, or as soon thereafter as is practicable, the Debtor will
(a) publicize the auction of the MAC Shares and Warrants by publishing the
Notice of Auction for the Purchase of Certain Property, a form of which is
attached hereto and incorporated herein by reference as Exhibit "B" (the
"Auction Notice"), in The Financial Times, and (b) serve a copy of the Auction
                      -------------------                                     
Notice by first class U.S. mail, postage pre-paid, on all creditors and
shareholders and any person or entity that has expressed to the Debtor a
substantial interest in bidding on the MAC Shares and Warrants.

                              Bidding Guidelines
                              ------------------

      12.  Any person, entity, or buyer who desires to purchase the MAC Shares
and Warrants (collectively, a "Competing Bidder") must be present at the Auction
(as hereinafter defined) and bid in accordance with the following procedures (a
"Competing Bid"):

                                       4
<PAGE>
 
           (a) The Debtor will not consider offers for less than all the MAC
               Shares and Warrants.

           (b) To be eligible for participation in the Auction (as hereinafter
               defined), offers must:

               (1)  be in writing and received by the Debtor's respective
                    undersigned counsel no later that two (2) days prior to the
                    date established for the Auction;

               (2)  be made on terms and conditions that are substantially
                    similar to those set forth in the Postpetition Asset
                    Purchase Agreement;

               (3)  contain a minimum initial bid providing consideration at
                    least $2,000,000 higher than the consideration provided by
                    the Purchase Offer;

               (4)  be accompanied by a refundable deposit of 10% of the
                    Competing Bid, payable in cash, certified check or cashier's
                    check, which shall be delivered to the Debtor not later than
                    the commencement of the Hearing;

               (5)  not be contingent upon any unperformed due diligence
                    investigation by the Competing Bidder, the receipt of
                    financing or any board of directors, shareholders or other
                    corporate approval;

               (6)  close the transaction prior to July 1, 1998;

               (7)  be accompanied by proof in a form satisfactory to the Debtor
                    of the Competing Bidder's financial ability to consummate
                    its offer to purchase the MAC Shares and Warrants;

               (8)  be in the form of a final written contract that will contain
                    terms and conditions substantially similar to the
                    Postpetition Asset Purchase Agreement signed by the
                    Competing Bidder which, when and if determined by the Debtor
                    and the Court to be the highest and best offer for the MAC
                    Shares and Warrants (the "Successful Bid"), can be
                    immediately countersigned by the Debtor and shall constitute
                    a binding agreement between the parties thereto; and

               (9)  acknowledge that the offer shall remain open and irrevocable
                    until the earlier of (a) entry of an order approving the
                    sale of the MAC Shares and Warrants, or (b) consummation of
                    an agreement with any Competing Bidder.

                                       5
<PAGE>
 
           (c)  All offers are subject to approval of the Court at the Hearing.

                                  The Auction
                                  -----------

      13.  The Debtor will conduct the Auction beginning at 10:00 a.m on the
date of the Hearing and continue if necessary, from day to day until completed,
at the offices of Klehr, Harrison, Harvey, Branzburg & Ellers LLP, 1401 Walnut
Street, Philadelphia, Pennsylvania 19102.  At the Auction, VDC and all other
interested parties will submit their highest and best bids to purchase the MAC
Shares and Warrants.

      14.  For purposes of determining whether a Competing Bid is higher and
better than the Purchase Offer, the shares of VDC common stock will be valued
based upon the mean of the last bid and ask prices per share as listed on the
NASD Electronic Bulletin Board or other similar interdealer quotation system
through which bid and ask prices for VDC are submitted, or any national
securities exchange on which VDC is listed, for the consecutive five (5) trading
days immediately preceding the Auction.  In the event VDC is not trading on any
exchange for the five (5) days prior to the Auction, the value of VDC common
stock shall be the fair market value as reasonably determined by an investment
banking firm selected by the Debtor, with the costs of such appraisal to be
borne by the Debtor.

      15.  At the commencement of the Auction, the Debtor will announce which
bid (including the Purchase Offer and any Competing Bid) was the highest and
best initial offer (the "Opening Bid").  Thereafter, the Debtor will open the
bidding to submissions which are higher and better than the Opening Bid.  Such
bids, other than the minimum initial bid described in paragraph 12(b)(3) hereof,
must be submitted in minimum increments of $100,000, until such

                                       6
<PAGE>
 
time as the Debtor announces the Successful Bidder.

      16.  The Debtor reserves the sole discretion to determine which bidder is
the Successful Bidder.

      17.  At the time the Successful Bidder is announced at the Auction, and in
the event that such a Successful Bidder is a Competing Bidder, the Successful
Bidder shall increase its deposit to twenty (20%) percent of the Successful Bid,
which deposit shall be nonrefundable. If the Successful Bidder fails to increase
the deposit, the penultimate highest and best offer will be announced as the
Successful Bid, subject to the requirements of this paragraph.

      18.  No bidder in the Auction shall be entitled to any termination fee or
break-up fee (other than VDC, who may be entitled to a break-up fee under the
Postpetition Asset Purchase Agreement, as described below).

      19.  Following the Auction or as soon thereafter as the Court's calendar
permits, the Successful Bid shall be presented to the Court for approval at the
Hearing, so that the sale of the MAC Shares and Warrants can be approved and
authorized by the Court to the Successful Bidder.

                               The Sale Hearing
                               ----------------

      20.  The Debtor requests that the Court schedule the Hearing for April 15,
1998, or as soon thereafter as the Court's calendar permits.  At the  Hearing,
the Court shall consider the sale of the MAC Shares and Warrants and enter an
order (the "Sale Order") authorizing the sale of the MAC Shares and Warrants as
follows:

           i.  If VDC is the Successful Bidder for the MAC Shares and Warrants,
               the Debtor requests that the Court enter a Sale Order
               substantially similar in form to the proposed order attached to
               this Motion, modified as necessary

                                       7
<PAGE>
 
                to reflect the contents of the Successful Bid at the Auction;
                and

           ii.  If VDC is not the Successful Bidder for the MAC Shares and
                Warrants, the Debtor requests that the Court enter an
                alternative Sale Order approving the Debtor's sale of the MAC
                Shares and Warrants to the Successful Bidder.

      21.  If necessary, any alternative order will be submitted to the Court on
the day of the Hearing and will be substantially similar in form and substance
to the proposed order attached to the Motion, except as modified to reflect the
results of the Auction.

      22.  The sale of the MAC Shares and Warrants shall be without
representation or warranty of any kind, nature or description by the Debtor,
except as set forth in the Postpetition Asset Purchase Agreement.

                   Justifications for the Bidding Procedures
                   -----------------------------------------

      23.  The Debtor believes that the Bidding Procedures are the best way to
maximize the value of the MAC Shares and Warrants.

                               The Break-Up Fee
                               ----------------

      24.  The Postpetition Asset Purchase Agreement provides that, if VDC is
not the Successful Bidder with respect to the purchase of all of the MAC Shares
and Warrants (including a determination that a Competing Bidder is the
Successful Bidder), then the Debtor is required to pay a break-up fee equal to
$1,000,000 (the "Break-Up Fee") to VDC. The Debtor is required to pay the Break-
Up Fee in consideration of VDC's efforts and expenses incurred in connection
with the Postpetition Asset Purchase Agreement and the DIP financing. Thus, the
Debtor also hereby requests authority to pay the Break-Up Fee to the extent
required under the Postpetition Asset Purchase Agreement.

                                       8
<PAGE>
 
      25.  The Break-Up Fee is beneficial to the Debtor's estate and creditors.
VDC's Purchase Offer has established a floor for any further bidding on the MAC
Shares and Warrants.  If VDC is not the Successful Bidder at the Auction because
the Debtor receives a higher and better offer, the Debtor will have benefited
from the floor established by the Purchase Offer.

      26.  Approval of break-up fees and/or expense reimbursement in connection
with the sale of significant assets has become an established practice in
chapter 11 asset sales, enabling a debtor to assure a sale to a contractually
committed bidder at a price the debtor believes is fair, while providing the
debtor with the potential of obtaining even greater benefits for the estate
through an auction process.   This and other courts have approved break-up fees
in numerous other chapter 11 cases.  See, e.g., In re Kupp Acquisition Corp.,
                                     ---  ----  ----------------------------

airlines, Inc., Case No. 90-932 (HSB) (approval of $1.5 million breakup fee on

approximate purchase price of $61 million).

      27.  The Break-Up Fee is within the range established by the precedents
set forth above.   Assuming that the consideration offered by VDC has a value,
as of the Hearing, of at least approximately $30 million, the Break-Up Fee
represents less than four (4%) percent of the purchase price.  Further, the
Break-Up Fee is the result of the Debtor's prudent business judgment and has
been agreed upon to maximize the value of the MAC Shares and Warrants.  If
necessary, therefore, the Debtor should be authorized to pay the Break-Up Fee
pursuant to the Postpetition Asset Purchase Agreement.  See In re Integrated

                    1998);

               (2)  be made on terms and conditions that are substantially
                    similar to those set forth in the Postpetition Asset
                    Purchase Agreement;

               (3)  contain a minimum initial bid providing consideration at

                    check, which shall  be delivered to the Debtor not later
                    than the commencement of the hearing to approve the sale of
                    the MAC Shares and Warrants scheduled for April 23, 1998 at
                    2:30 p.m. (the "Hearing");

               (5)  not be contingent upon any unperformed due diligence
                    investigation by the Competing Bidder, the receipt of
                    financing or any board of directors, shareholders or other
                    corporate approval;

               (6)  agree to close the transaction prior to July 1, 1998;

               (7)  be accompanied by proof in a form satisfactory to the Debtor
                    of the Competing Bidder's financial ability to consummate
                    its offer to purchase the MAC Shares and Warrants;

               (8)  be in the form of a final written contract that will contain
                    terms and conditions substantially similar to the
                    Postpetition Asset Purchase Agreement signed by the
                    Competing Bidder which, when and if determined by the Debtor
                    and the Court to be the highest and best 

                                       2
<PAGE>
 
                    offer for the MAC Shares and Warrants (the "Successful
                    Bid"), can be immediately countersigned by the Debtor and
                    shall constitute a binding agreement between the parties
                    thereto; and

               (9)  acknowledge that the offer shall remain open and irrevocable
                    until the earlier of (a) entry of an order approving the
                    sale of the MAC Shares and Warrants, or (b) consummation of
                    an agreement with any Competing Bidder.

         (c) All offers are subject to approval of the Court at the Hearing.

     4.  At the Auction, the following procedure will be utilized:

         (a) VDC and all other interested parties will submit their highest
             and best bids to purchase the MAC Shares and Warrants.

         (b) For purposes of determining whether a Competing Bid is higher and
             better than the Purchase Offer, the shares of VDC common stock will
             be valued based upon the mean of the last bid and ask prices per
             share as listed on the NASD Electronic Bulletin Board or other
             similar interdealer quotation system through which bid and ask
             prices for VDC are submitted, or any national securities exchange
             on which VDC is listed, for the consecutive five (5) trading days
             immediately preceding the Auction. In the event VDC is not trading
             on any exchange for the five (5) prior to the Auction, the value of
             VDC common stock shall be the fair market value as reasonably
             determined by an investment banking firm selected by the Debtor,
             with the costs of such appraisal to be borne by the Debtor.

         (c) At the commencement of the Auction, the Debtor will announce
             which bid (including the Purchase Offer and any Competing Bid) was
             the highest and best initial offer (the "Opening Bid"). Thereafter,
             the Debtor will open the bidding to submissions which are higher
             and better than the Opening Bid. Such bids, other than the minimum
             initial bid described in paragraph 3(b)(3) above, must be submitted
             in minimum increments of $100,000, until such time as the Debtor
             announces the Successful Bidder.

         (d) The Debtor reserves the sole discretion to determine which bidder
             is the Successful Bidder.

         (e) At the time the Successful Bidder is announced at the Auction, and
             in the event that such a Successful Bidder is a Competing Bidder,
             the Successful Bidder shall increase its deposit to 20% of the
             Successful Bid, which deposit shall be nonrefundable. If the
             Successful Bidder fails to increase

                                       3
<PAGE>
 
               the deposit, the penultimate highest and best offer will be
               announced as the Successful Bid, subject to the requirements of
               this paragraph.

     5.  A hearing to approve the sale of the MAC Shares and Warrants to the
highest and best bidder will be held on April 23, 1998 at 2:30 p.m. (Prevailing
Eastern Time) at the Bankruptcy Court, 824 N. Market Street, 6th Floor,
Wilmington, Delaware 19801.

     6.  This Notice is qualified in its entirety by the Order.

     7.  Copies of the Order and the Postpetition Asset Purchase Agreement, as
amended, are available upon request, at the Debtor's expense, from (a) Delaware
Legal Copy (302) 426-1500, or (b) the below-listed counsel.
