  STIPULATION REGARDING MOTION OF VDC CORPORATION LTD. FOR RECONSIDERATION AND
PARTIAL STAY OF CONFIRMATION ORDER PENDING COMPLETION OF FED. R. BANKR. P. 2004
  EXAMINATIONS TO INVESTIGATE GROUNDS FOR POSSIBLE REVOCATION OF CONFIRMATION

     This Stipulation is made and entered into this 20th day of October, 1998,
by and among PortaCom Wireless, Inc., ("Debtor"), the Official Committee of
Unsecured Creditors of the Debtor ("Committee"), Klehr, Harrison, Harvey,
Branzburg & Ellers ("Escrow Agent"), Michael Richards ("Disbursing Agent") and
VDC Corporation Ltd. ("VDC").

                                   BACKGROUND
                                   ----------

     A.   On March 23, 1998 ("Petition Date"), PortaCom Wireless, Inc.
("Debtor") filed a Voluntary Petition for relief under Chapter 11 of Title 11 of
the United States Code ("Code").

     B.   The Debtor is in control of its property and is maintaining and
managing its business as a debtor-in-possession pursuant to Code (S)(S) 1107 and
1108.

     C.   On or about July 24, 1998, the Debtor filed an Amended Plan of
Reorganization As Modified ("Amended Plan") and accompanying Disclosure
Statement.

     D.   By Order dated September 17, 1998 ("Confirmation Date"), this Court
confirmed the Amended Plan ("Confirmation Order").  The Amended Plan was
confirmed pursuant to Code 

 
(S) 1129(a) and without objection.

     E.   Prior to the commencement of the within bankruptcy case, on September
30, 1997, the Debtor and VDC entered into an agreement to acquire the Debtor's
interest in MCC, consisting of 2,000,000 shares of MCC common stock ("MCC
Shares") and warrants to purchase 4,000,000 shares of MCC common stock with a
strike price of $4.00 per share ("Warrants"), in consideration of VDC's issuance
of 5.3 million shares of VDC common stock and up to $700,000 in cash ("1997 Sale
Agreement").  The 1997 Sale Agreement was superseded by the Asset Purchase
Agreement dated March 23, 1998 ("Asset Purchase Agreement").

     F.   The Asset Purchase Agreement, was subsequently amended by two
Stipulations and Orders in Lieu of Objection, dated as of April 3, 1998 and
April 23, 1998, respectively (collectively, the "Stipulations") and by an Escrow
Agreement ("Escrow Agreement"), which provided for an escrow account in the
amount of $2,682,000 funded by VDC, subject to adjustment, for the holders of
Unsecured Claims against the Debtor.

     G.   Pursuant to the Escrow Agreement, VDC has delivered the escrowed funds
to the Debtor's special transactional counsel, as Escrow Agent, together with
5,300,000 VDC Shares as provided in the Asset Purchase Agreement.

     H.   In addition, pre-petition funding was also provided to the Debtor by
VDC, whereby VDC agreed to extend credit and advance funds to the Debtor in an
amount not to exceed $700,000. As of the Petition Date, VDC had advanced
approximately $370,000 to the Debtor, which sum, together with all accrued
interest, costs and other charges constituted the pre-petition indebtedness to
VDC ("Pre-Petition Indebtedness").

     I.   On or about June 8, 1998, the Debtor and VDC entered into a Memorandum
of Understanding ("MOU"), which provided for a procedure for distribution of VDC
Shares.  The MOU constitutes an amendment to the Asset Purchase Agreement by
virtue of the entry of the 

 
Confirmation Order, to the extent set forth in the Confirmation Order.

     J.   Pursuant to (S) 3.3, 7.6 and 7.7 of the MOU, the Debtor is required to
retain the VDC Shares delivered from the Escrow Agent until such time as a
transfer or other disposition of such shares occurs to the Debtor's creditors
and stockholders pursuant to (a) a confirmed plan of reorganization providing
for the transfer of the VDC Shares, or (b) an effective Registration Statement
in accordance with the provisions of (S) 7.6 of the MOU.  Except as provided for
in (S)(S) 7.6 and 7.7 and subject to (S) 3.4(h) of the MOU, the VDC Shares were
issued in three series, the First Series of 25% of the VDC Shares ("First
Series") being transferable immediately upon the Confirmation Date; the Second
Series of 25% of the VDC Shares ("Second Series") being transferable six months
thereafter; and the Third Series of 50% of the VDC Shares ("Third Series") being
transferable on the first anniversary of the Confirmation Date.

     K.   VDC filed a motion seeking reconsideration, and a stay, of the
Confirmation Order ("Motion") in order to conduct Fed. R. Bankr. P. 2004
examinations of representatives of the Debtor, MCC and others involved in the
promotion of the sale to VDC for the purposes of determining whether there are
grounds for revocation of confirmation pursuant to Code (S) 1144, in particular,
whether principals of the Debtor and others with economic interests in the
transaction, made fraudulent representations to induce VDC to enter into the
Asset Purchase Agreement, thereby resulting in a Confirmation Order which was
procured by fraud.  Debtor and the Committee dispute VDC's allegations and filed
objections to the Motion.

     L.   The parties hereto have entered into this Stipulation in order to
resolve the issues raised by VDC, as well as certain other issues and disputes
that have arisen in contemplation of implementation of the Plan.

     NOW, THEREFORE, intending to be legally bound hereby, for and in 
consideration of

 
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, subject to approval by the Court after notice and hearing the
parties hereto agree as follows:

     1.   The Background section set forth above is incorporated herein as
though set forth below at length.

     2.   Debtor, the Escrow Agent, as defined above and in the MOU, and
Disbursing Agent, as defined above and in the Plan, agree to defer making
distributions of VDC Shares, as defined in the Asset Purchase Agreement, to the
Class 6 equity holders of Debtor, except in accordance with the terms of this
Stipulation and only for the period specified in paragraph 3 hereof, set forth
more fully below.

          a.   Upon the entry of this Stipulation on the docket of the Debtor's
case, or as soon as is reasonably practicable thereafter, the Escrow Agent shall
disburse to VDC the Returned Shares, as defined in the MOU, and as calculated
below, and to the Disbursing Agent the remainder of the First Series and Second
Series.

          b.   Of the VDC Shares delivered by the Escrow Agent to the Disbursing
Agent in accordance with sub-paragraph a above, the Disbursing Agent shall (i)
retain the difference between (I) the sum of the First Series and Second Series
delivered by the Escrow Agent and (II) the Returned Shares, as defined in the
Plan, and may distribute the same to creditors holding claims in Classes 1
through 5 under the Plan, except as limited hereby; (ii) of the VDC Shares
retained by the Disbursing Agent pursuant to clause (i) above, retain 102,320
additional VDC Shares (the "Returned Shares Escrow Shares") in escrow until the
Disputed 

 
Claims that are the subject of the Disputed Claims Reserve under the Plan are
allowed or disallowed, in whole or in part, by a Final Order; and (iii) disburse
the Returned Shares to VDC in accordance with paragraph 9 below. The Returned
Shares Escrow Shares shall consist of VDC Shares in the Second Series referenced
in the MOU.

          c.   The Disbursing Agent's distributions of VDC Shares as described
above shall in all respects, except as specifically described herein, comport
with the terms of the Plan and Confirmation Order. The Court shall retain
jurisdiction to hear and determine any and all disputes which may arise under or
in the implementation of this Stipulation.

     3.   None of the Debtor, Committee, Escrow Agent or Disbursing Agent shall
file any pleading or otherwise seek to shorten the period of deferral of the
distribution of the VDC Shares to Class 6 equity holders under this Stipulation,
except to enforce the terms hereof. Notwithstanding anything herein to the
contrary, the deferral agreed to hereby shall dissolve and be of no further
force or effect as of the 165th day following the entry of the Confirmation
Order (the period of deferral shall expire at 5:00 p.m. on March 2, 1998
prevailing Eastern time), unless VDC shall obtain a further order of the Court
prior to the 165th day following the Confirmation Date.  Debtor and VDC shall
cooperate in good faith with respect to VDC's investigation of fraud in
connection with the Asset Purchase Agreement, including, without limitation, the
scheduling of depositions/examinations and production of documents, which duty
of cooperation shall be reciprocal.  The Court shall retain jurisdiction to hear
and determine any and all discovery/examination disputes.

     4.   The Motion shall be and is withdrawn with prejudice.  The Confirmation
Order in 

 
all respects shall become and is a Final Order, as defined in the Plan. Debtor,
Escrow Agent and Disbursing Agent are hereby authorized and directed immediately
to implement the Plan, except with respect to making disbursements to the Class
6 equity holders of cash or VDC Shares, as provided herein. Nothing herein is
intended or shall prejudice or alter the rights of creditors holding claims in
Classes 1, 2 and 5 under the Plan and Confirmation Order.

     5.   Notwithstanding the withdrawal with prejudice of the Motion, all of
VDC's rights, claims, causes of action and remedies as to any and all parties
shall be and hereby are reserved, including, without limitation, VDC's remedy of
rescission of the Asset Purchase Agreement; and Debtor's rights, claims and
causes of action as to any and all parties shall be and hereby are reserved.
Notwithstanding anything herein to the contrary, VDC, its successors and
assigns, shall not seek to disgorge or otherwise recover from the Debtor, Escrow
Agent, Escrowed Funds, Disbursing Agent, reserves or funds maintained by the
Disbursing Agent, or creditors of the Debtor's estate funds that are payable or
have been paid to and on account of creditors holding Allowed Claims in Classes
1, 2 and 5 under the Plan, or otherwise paid to administrative creditors (it
being the express intention of the parties hereto that VDC's remedies would be
exercised only against the Second Series and Third Series retained by the
Disbursing Agent and to affect an indefeasible distribution to the creditors
holding claims in Classes 1, 2 and 5), except that nothing herein shall act to
release any claim, action or right of recovery of VDC against individual
creditors that are determined to have participated, aided, abetted, assisted or
conspired in the alleged fraud.  Furthermore, to the extent that the assets of
the estate are insufficient to satisfy VDC's claims and any claims with priority
over the claims in Class 5, VDC will agree to reduce its claim against the
Debtor accordingly so as prevent the disgorgement of distributions to the
Classes 2 and 5 creditors.

 
     6.   Attached hereto and made a part hereof is a schedule of Allowed Claims
treated in Classes 2 and 5 under the Plan that are to be paid out of the
Escrowed Funds.  The Schedule reflects that $1,402,200.00 is payable to the
holders of Allowed Claims in Classes 2 and 5.  The Schedule further reflects
that $714,645.24 is to be reserved under the Plan until the entry of an Order
resolving the Debtor's objections to certain claims.

     7.   On September 25, 1998, the Escrow Agent disbursed to VDC $192,754.00
on account of a portion of the 60% Credits, as defined in the Plan, due to VDC.
From time to time, the Debtor made requests of the Escrow Agent to fund
administrative expenses from the Escrowed Funds in the aggregate amount of
$82,000.  On or about June 8, 1998, the Escrow Agent disbursed to Debtor the sum
of $41,412.00, representing the Bar Date Claims and Closing Date Claims, both as
defined in the Escrow Agreement.  As of October 16, 1998, the Escrow Account, as
defined in the Escrow Agreement, contains $2,427,979.72, including principal,
interest and other earnings thereon.

     8.   The Escrow Agent is hereby authorized and directed forthwith to
disburse from the Escrow Account to: (a) Disbursing Agent the sum of $714,645.24
for deposit into the Disputed Claims Reserve Fund, as defined in the Plan; and
(b) VDC the sum of $311,134.48, plus any and all interest and earnings thereon
(from time to time when received), plus any other funds existing, remaining or
otherwise in the Escrow Account or comprising the Escrowed Funds. The Escrow
Agent's obligation to disburse the remainder of the Escrow Account to VDC shall
be continuing from time to time so long as such Account continues to earn or
accrue income, interest, dividends or other revenues.

 
     9.   Pursuant to the Asset Purchase Agreement, certain VDC Shares are to be
returned to VDC in connection with the post-closing adjustments.  The number of
Returned Shares is equal to 159,526 (($1,484,400 - $370,000)/$6.98446 per VDC
Share).  The Returned Shares shall comprise VDC Shares in the Second Series, as
defined in the MOU.

     10.  The Disbursing Agent shall forthwith upon the entry of a Final Order
on objections to the allowance in whole or in part of claims treated in Classes
2 and 5 under the Plan, disburse the Returned Shares Escrow Shares and funds
from the Disputed Claims Reserve Fund to: (a) the creditor the amount, if any,
of such creditor's Allowed Claim; (b) VDC the amount, if any, of such creditor's
claim that was disallowed, expunged, or otherwise that has not become an Allowed
Claim, plus a corresponding portion of the Returned Shares Escrow Shares
(calculated in accordance with the Asset Purchase Agreement); and (c) VDC the
balance of the Returned Shares Escrow Shares and the Disputed Claims Reserve
Fund after resolution of all Disputed Claims with respect to which the Disputed
Claims Reserve Fund was funded, plus any and all interest and earnings thereon
(from time to time when received), plus any other funds existing, remaining or
otherwise in or comprising the Disputed Claims Reserve Fund.  The Disbursing
Agent's obligation to disburse the remainder of the Disputed Claims Reserve Fund
to VDC shall be continuing from time to time so long as such Fund continues to
earn or accrue income, interest, dividends or other revenues.

     11.  Pursuant to the Asset Purchase Agreement, one million VDC Shares may
immediately be liquidated in order to fund the Plan with respect to the holders
of Allowed Claims in Classes 1 through 5 and otherwise pay administrative
claims.

 
     12.  VDC has filed an application for allowance of an administrative claim
in the amount of $18,000.00.  No objections have been interposed to the
application.  The parties hereto consent to the entry of an Order approving the
application and allowing to VDC an administrative claim in the amount of
$18,000.00.  VDC's allowed administrative claim shall be paid in full together
with the payment of the Class 1 Allowed Claims under the Plan. Notwithstanding
the foregoing, the Debtor and the Committee reserve their respective rights and
claims against VDC in connection with the Motion and other acts and omissions of
VDC after the date of this Stipulation.

     13.  Upon VDC's indefeasible receipt of the funds from the Escrow Agent and
Disbursing Agent and the Returned Shares, all as provided for herein, the Pre-
Petition Indebtedness shall be forgiven and deemed satisfied.

     14.  This Stipulation sets forth the entire agreement of the parties hereto
with respect to the subject matter hereof and may be amended only by a writing
signed by each party hereto and approved by the Court.

     15.  This Stipulation shall inure to and be binding upon the parties hereto
and their respective successors and assigns upon approval hereof by an Order of
the Court.

     16.  Counsel signing this Stipulation on behalf of the parties hereto each
represent that they have all the requisite authority to bind their client
hereto.

 
     17.  This Stipulation may be executed in counterparts.

     IN WITNESSETH WHEREOF, the parties hereto through their duly authorized
counsel, have signed this Stipulation the day and year first above written.
