EXHIBIT 10.11 CLOSING ESCROW AGREEMENT ------------------------ This CLOSING ESCROW AGREEMENT ("Agreement") is made as of the 8 day of June, 1998, by and among VDC Corporation Ltd. ("Buyer"), PortaCom Wireless, Inc. ("Debtor"), Metromedia China Corporation ("MCC"), the Official Committee of Unsecured Creditors of PortaCom Wireless, Inc. ("Committee"), and Klehr, Harrison, Harvey, Branzburg & Ellers LLP ("Closing Escrow Agent"). BACKGROUND ---------- A. 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"). B. The Office of the United States Trustee thereafter appointed the Committee. C. Prior to the commencement of the Case, Debtor and Buyer were parties to an asset purchase agreement and amendments thereto, pertaining to Debtor's agreement to sell to Buyer its interest in and to 2,000,000 shares of common stock ("MAC Shares") of Metromedia Asia Corporation, predecessor in interest to MCC ("MAC"), and warrants to purchase an additional 4,000,000 shares of MAC common stock with a strike price of $4.00 per share ("MAC Warrants"). D. 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. The Purchase Agreement was amended by (a) two Stipulations and Orders in Lieu of Objection, dated as of April 3, 1998 and April 23, 1998, respectively (collectively, the "Stipulations"), by and among Debtor, VDC and the Committee; and (b) the Escrow Agreement (the "Escrow Agreement"), dated April __, 1998, among Debtor, VDC, the Committee and Klehr, Harrison, Harvey, Branzburg & Ellers LLP as Escrow Agent. E. 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 ("Procedures Motion") with respect to the Purchase Agreement, and the Debtor's Motion for Approval of the Sale of the Debtor's Interest in Property of the Estate Free and Clear of Liens, Claims and Encumbrances Pursuant to 11 U.S.C. (S) 363(b) and (f) and Federal Rule of Bankruptcy Procedure 6004 ("Sale Motion"). F. On April 23, 1998, the United States Bankruptcy Court for the District of Delaware 1 (the "Court") entered an order (the "Sale Order") approving the Purchase Agreement and authorizing the sale of the MAC Shares and Warrants free and clear of any liens or encumbrances, including MCC's first priority security interest in the MCC Shares (the "MCC Lien"). Pursuant to the Sale Order and section 363 of the Bankruptcy Code, the MCC Lien attached to the sale proceeds (the "Replacement Lien"), including certain shares of common stock of VDC (the "VDC Shares"). G. Pursuant to that certain pledge agreement dated June 8, 1998 between the Debtor and MCC (the "Pledge Agreement"), MCC has agreed that the Replacement Lien is limited to 50% of the Debtor's interest in the VDC Shares deliverable to the Debtor under the Purchase Agreement dated March 23, 1998, as amended. Pursuant to the Pledge Agreement, in order for MCC to perfect the Replacement Lien, the Debtor has agreed that 2.65 million VDC Shares will be pledged to MCC (the "Pledged Shares"), subject to the terms of the Pledge Agreement. H. Buyer has demanded that, as a condition for closing under the Purchase Agreement, the Debtor deliver to Buyer a newly issued stock certificate representing the MAC Shares and a newly issued warrant certificate representing the MAC Warrants, each in the name of Buyer (collectively, the "Reissued Shares and Warrants"). I. This Closing Escrow Agreement is delivered in furtherance of the closing of the sale of the MAC Shares and Warrants, that commenced on June 8, 1998 at the offices of Buchanan Ingersoll Professional Corporation (the "Closing"). NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto do hereby agree as follows: 1. The foregoing recitals are hereby incorporated in this Agreement as though set forth at length herein. 2. Appointment of Closing Escrow Agent.
