To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:
We have been appointed by Europe Acquisition, Inc. ("Europe Acquisition"), a Delaware corporation and an indirect wholly-owned subsidiary of UnitedGlobalCom, Inc., a Delaware corporation ("United"), to act as Dealer Manager in connection with Europe Acquisition's offer to exchange 10.3 shares of the Class A common stock of United ("United Shares") for each outstanding share of common stock, par value $0.01 per share ("UGC Europe Shares"), of UGC Europe, Inc., a Delaware corporation ("UGC Europe"), not owned by United or its subsidiaries, upon the terms and subject to the conditions set forth in the Prospectus, dated November 26, 2003 (as it may be amended, the "Prospectus"), amending and restating in its entirety the original Prospectus dated October 6, 2003, and in the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the "Exchange Offer"). Please furnish copies of the enclosed materials to those of your clients for whose accounts you hold UGC Europe Shares registered in your name or in the name of your nominee.
WE URGE YOU TO CONTACT YOUR CLIENTS AS PROMPTLY AS POSSIBLE. PLEASE NOTE THAT THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 PM, NEW YORK CITY TIME, ON THURSDAY, DECEMBER 18, 2003, WHICH DATE MAY BE EXTENDED.
For your information and for forwarding to your clients for whom you hold UGC Europe Shares registered in your name or in the name of your nominee, we are enclosing the following documents:
1. The Prospectus, dated November 26, 2003.
2. The Letter of Transmittal for your use in accepting the Exchange Offer and tendering UGC Europe Shares and for the information of your clients.
3. The Notice of Guaranteed Delivery to be used to accept the Exchange Offer if certificates evidencing UGC Europe Shares are not immediately available, or if the procedures for tendering UGC Europe Shares set forth in "Chapter II—The Transaction—The Exchange Offer,
Procedure for Tendering Shares" in the Prospectus cannot be completed on or prior to the Expiration Date.
4. A printed form of letter which may be sent to your clients for whose accounts you hold UGC Europe Shares registered in your name or in the name of your nominee, with space provided for obtaining such clients' instructions with regard to the Exchange Offer.
Please note the following:
1. The consideration per UGC Europe Share has been increased to 10.3 United Shares, as described in the Prospectus.
2. The Exchange Offer is being made for all outstanding UGC Europe Shares not owned by United or its subsidiaries.
3. The Exchange Offer has been approved by a special committee of UGC Europe's board of directors as described in the Prospectus.
4. THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 PM, NEW YORK CITY TIME, ON THURSDAY, DECEMBER 18, 2003, WHICH DATE MAY BE EXTENDED BY EUROPE ACQUISITION.
5. The "Minimum Tender Condition" to the Exchange Offer has been eliminated. In addition, the "90% Condition" has been made non-waivable. To satisfy the "90% Condition," a sufficient number of UGC Europe Shares must have been validly tendered and not properly withdrawn, such that following the acceptance of such UGC Europe Shares for exchange pursuant to the Exchange Offer, United and its subsidiaries will collectively own at least 90% of the issued and outstanding UGC Europe Shares, determined on a fully diluted basis. The Exchange Offer is also subject to the other conditions set forth in the Prospectus. See "Chapter II—The Transaction—The Exchange Offer— Certain Conditions of the Exchange Offer" in the Prospectus.
6. Cash will be paid in lieu of any fraction of a United Share to which a stockholder would be entitled. U.S. Stockholders who fail to complete and sign the Internal Revenue Service Form W-9 attached to the Letter of Transmittal, and foreign stockholders who fail to complete and sign an appropriate Internal Revenue Service Form W-8, may be subject to a required federal backup withholding tax of 28% in connection with the Exchange Offer.
7. Notwithstanding any other provision of the Exchange Offer, exchange for UGC Europe Shares accepted for exchange pursuant to the Exchange Offer will in all cases be made only after timely receipt by the Exchange Agent of (a) certificates evidencing such UGC Europe Shares (or a confirmation of a book-entry transfer of such UGC Europe Shares (a "Book-Entry Confirmation") into the Exchange Agent's account at The Depository Trust Company), (b) a Letter of Transmittal, properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent's Message (as defined in the Letter of Transmittal) in lieu of the Letter of Transmittal) and (c) any other documents required by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at different times depending upon when certificates for UGC Europe Shares or Book-Entry Confirmations with respect to UGC Europe Shares and all other required documents are actually received by the Exchange Agent. Stockholders that delivered an original Letter of Transmittal previously distributed with the original Prospectus, dated October 6, 2003, are not required to deliver a revised Letter of Transmittal distributed with the Prospectus, dated November 26, 2003 to validly tender UGC Europe Shares.
In order to take advantage of the Exchange Offer, certificates for all tendered UGC Europe Shares in proper form for transfer (or a Book-Entry Confirmation with respect to all such shares), together with a properly completed and duly executed Letter of Transmittal, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent's Message in lieu of the Letter
2
of Transmittal), and any other required documents must be received by the Exchange Agent on or prior to the Expiration Date, all in accordance with the instructions set forth in the Letter of Transmittal and the Prospectus.
Any stockholder who desires to tender UGC Europe Shares and whose certificates for UGC Europe Shares are not immediately available, or who cannot comply with the procedures for book-entry transfer on a timely basis, or who cannot deliver all required documents to the Exchange Agent prior to the Expiration Date, may tender such UGC Europe Shares by following the procedures for guaranteed delivery set forth in "Chapter II—The Transaction—The Exchange Offer, Procedure for Tendering Shares" in the Prospectus.
Europe Acquisition will not pay any fees or commissions to any broker, dealer or other person for soliciting tenders of UGC Europe Shares pursuant to the Exchange Offer (other than the Dealer Manager, the Exchange Agent and the Information Agent as described in the Prospectus). Europe Acquisition will, however, upon request, reimburse you for customary mailing and handling expenses incurred by you in forwarding any of the enclosed materials to your clients. Europe Acquisition will only pay transfer taxes imposed on Europe Acquisition in connection with the transfer of UGC Europe Shares pursuant to the Exchange Offer.
