     This Amended Stipulation and Order In Lieu of Objection ("Stipulation") is

                             W I T N E S S E T H:

     WHEREAS, on March 23, 1998, Debtor filed a voluntary petition for relief
under Chapter 11 of Title 11 of the United States Code ("Code"), commencing a
case in the United States Bankruptcy Court for the District of Delaware (the
"Court"), which is pending at number 98-661 (the "Case"); and

     WHEREAS, on March 29, 1998, the Office of the United States Trustee
convened a meeting of the twenty largest unsecured creditors of the Debtor for
the purpose of appointing a committee of creditors; and

     WHEREAS, the Office of the United States Trustee appointed three creditors

Shares") of Metromedia Asia Corporation ("MAC") and warrants to purchase an
additional 4,000,000 of MAC common stock with a strike price of $4.00 per share
("MAC Warrants"); and

     WHEREAS, the Debtor and Buyer negotiated the terms of an asset purchase
agreement to be entered into in the Case and approved by the Court ("Purchase
Agreement") and agreed upon the procedures pursuant to which the Purchase
Agreement would be submitted to the Court for approval; and

     WHEREAS, together with the petition commencing the Case, the Debtor filed
the Motion Of Debtor (A) To Establish Bidding Procedures And To 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 ("Motion") with
respect to the Purchase Agreement, which is attached to the Motion as Exhibit A;

"Successful Bidder;" and
<PAGE>
 
     NOW, THEREFORE, intending to be legally bound hereby, for and in
consideration of the mutual covenants set forth below, the parties agree as
follows:

     1.  The recitals set forth above are incorporated herein as though set
forth below at length.

     2.  The Purchase Agreement is incorporated herein and shall be amended
pursuant to the terms set forth below.  Capitalized terms used herein and not
defined herein shall have the meaning ascribed to such term in the Purchase
Agreement.

     3.  Section 1.1 shall be amended by adding a new definition, as follows:

          "Allowed Claims" means the pre-petition unsecured claims, as defined
          in Code (S) 101(5), or portion thereof, that: (a) are allowed pursuant
          to a final, non-appealable Order of the Court, or (b) are deemed
          allowed pursuant to Code (S) 1111(a), or (c) are the subject of pre-
          petition settlement agreement, or post-petition settlements agreement
          approved by the Court, that provide for the payment of cash, in whole
          or in part, in settlement and satisfaction thereof, and in such case,
          the cash portion thereof (collectively, the "Settlements").  Debtor's
          counsel believes the Settlements are enforceable and will vigorously
          attempt to enforce them in the Chapter 11, to the extent necessary.

          "Cash Purchase Escrow" means that segregated, interest bearing escrow
          account established and maintained by the Debtor, funded by Buyer, in
          an amount equal to $2.6 million.  The Cash Purchase Escrow may be
          funded by any combination of cash and stand-by letter of credit;
          provided, however, that the cash portion shall be in the minimum
          amount of $1,250,000.  The holders of priority unsecured claims and
          general unsecured claims shall be the beneficiaries of this fund.

          "Disputed Claims" means any pre-petition, unsecured claim that is not
          an Allowed Claim, by virtue of its being scheduled by the Debtor as
          disputed, contingent or unliquidated, and proof of which has not been
          timely filed, or as to which an objection has been interposed and
          which is pending as of Closing.

     4.  Section 3.2 of the Purchase Agreement is hereby amended by deleting the
section in its entirety and replacing it with the following:

          3.2  Closing Purchase Price.  The Closing Purchase Price (the "Closing
               ----------------------                                           
          Purchase Price") shall be paid or delivered by Buyer at Closing in the
          following manner:
<PAGE>
 
          (a) Subject to adjustment pursuant to Section 3.4 hereof, Buyer shall
          deliver the Cash Purchase Escrow (the "Cash Funds") to the Cash
          Purchase Escrow escrow agent ("Escrow Agent") for the benefit of
          Seller; and

          (b) Buyer shall deliver newly issued shares of common stock, par value
          $2.00 per share, of Buyer in accordance with the provisions of Section
          3.3 hereof (the "VDC Shares").  The number of VDC Shares to be
          delivered shall equal the difference between (i) 5,300,000 and (ii)
          the difference between the principal amount of the Cash Purchase
          Escrow delivered to Seller at Closing and the Indebtedness, divided by
          the value of the VDC stock valued consistently with paragraph 14 of
          the Motion.  For example, if the funds of the Cash Purchase Escrow
          delivered to Seller at Closing are in the amount of $2,000,000, the
          Indebtedness is $366,125 and the value of the VDC Shares is $6.00, the
          number of VDC Shares to be delivered is equal to 5,027,688 shares
          (5,300,000 - ((2,000,000 - 366,125)/6)); and

          (c) The Indebtedness shall be satisfied by Seller's delivery, in its
          capacity as escrow agent, to Buyer of that portion of the Cash
          Purchase Escrow, together with all accrued interest and other earnings
          thereon, not delivered to Seller pursuant to sub-section (a) above.

     5.  Section 3.4 of the Purchase Agreement is hereby amended by adding to
the end of the paragraph, the following:

          Following the Closing, from time to time, Disputed Claims, or a
          portion thereof, may become Allowed Claims.  To the extent that any
          Disputed Claim becomes an Allowed Claim, the Escrow Agent shall
          deliver to the Seller for distribution to the holder thereof the
          amount of such Allowed Claim; to Buyer 60% of the disallowed amount of
          the Disputed Claim; and the Escrow Agent shall retain the balance.

     6.  The Cash Purchase Escrow shall be funded the later of April 8, 1998 or
forty-eight (48) hours after entry by the Court of an Order approving this
Stipulation and upon the satisfaction of the condition identified in paragraph 7
below.

     7.  Debtor, or its counsel, shall be appointed escrow agent with respect to
the Cash Purchase Escrow.  The Cash Purchase Escrow shall be established and
invested in a money market or federally backed instrument.  Interest and all
other earnings on the Cash Purchase
<PAGE>
 
Escrow shall inure to the benefit of Buyer. The excess Cash Purchase Escrow, or
any portion thereof, shall be returned to Buyer from time to time at such time
as any Disputed Claim becomes an Allowed Claim. The amount returned to Buyer
shall be 60% of the amount which is disallowed. All other terms and conditions
of the escrow shall be set forth in an agreement mutually acceptable to the
Debtor, Buyer and the Committee, which shall be executed as a condition
precedent to the funding of such escrow.

     8.  Upon approval of the Purchase Agreement by the Court and confirmation
of Buyer as the Successful Bidder and approved purchaser thereunder, 10% of the
Cash Purchase Escrow shall become non-refundable as to Buyer, except in the
event of a default by Seller under the Purchase Agreement.

     9.  The Debtor In Possession Loan, Security and Pledge Agreement between
the Debtor and Buyer, approved by interim order entered on March 25, 1998 ("DIP
Financing Agreement"), shall be deemed modified by reducing the amount of
advances available thereunder post-petition to $100,000.00.

     10. Except as expressly modified hereby, the Purchase Agreement, Motion,
Notice and DIP Financing Agreement shall remain in full force and effect.

     11. The Committee hereby waives any and all objections to the Motion,
Notice and approval of the Purchase Agreement by the Court and confirmation of
Buyer as the Successful Bidder and approved purchaser thereunder.

     12. The Debtor shall use its best efforts to review the claims asserted
against the estate and interpose and pursue objects thereto.  Any and all
objections to claims shall be filed on or before May 15, 1998.
<PAGE>
 
     13.  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.

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

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

     16.  This Stipulation may be executed in counterparts.

counsel, have signed this Stipulation the day and year first above written.
