Exhibit 10.5
 GIGABIT TECHNOLOGY LICENSE AGREEMENT
  RECITALS
        1.
    
    TECHNOLOGY LICENSES
 1.1
    
    In consideration of the sums to be paid to 3Com as set forth in Section 2,
subject to all terms and conditions set forth in this Agreement, 3Com hereby grants to
the Realtek Group and Realtek Subsidiaries a fully paid-up, non-exclusive,
non-sublicensable license to make, have made, use, offer to sell, sell, and import the
Covered Products (as defined below) in the United States under the Licensed Gigabit
Technology (as defined below), from the date of issue of the Gigabit Patents until the
last expiration date of the patents within the Licensed Gigabit Technology.
Notwithstanding the foregoing, this license shall not take effect until payment is made
under Section 2.1 below, and shall then take effect only if, at that time, Realtek is
in full compliance with the terms of this Agreement and any other license agreements
between the Parties. Licensed Gigabit Technology shall include: (i) the Gigabit
Patents; (ii) all United States patents which claim priority to or through any of the
Gigabit Patents or that are listed as related applications in any of the Gigabit
Patents; (iii) all related United States

continuation, continuation-in-part, parents, ancestors, children, descendants,
divisional, reissue, extension and reexamination patents, and all corresponding
foreign patents and other counterparts of the Gigabit Patents described in
subparagraphs (i) and (ii) above, together with all patents anywhere in the world
which claim priority (in whole or in part, directly or indirectly) from any of the
foregoing patents or from any patent applications from which any of the foregoing
patents issued or issue; and (iv) all technical, manufacturing and production
know-how, processes, protocols, standard operating procedures, and product designs
related to the technology of the Gigabit Patents in the Covered Products that are or
were developed by the Realtek Group and/or any Realtek Subsidiary, and are or were
utilized by any of them in the design and/or manufacture of Covered Products,
provided, however, that such license shall not include any other patent owned by
3Com whatsoever. Covered Products shall mean those products identified in Exhibit
A hereto, and any later versions thereof or other products technologically derived
therefrom (in whole or in part) and any network adapter and/or interface devices or
components, in each case that are (a) made by or for Realtek and/or its Subsidiaries
(as defined below), and (b) sold by Realtek and/or its Subsidiaries to their direct
customers (including, without limitation, distributors) as a Realtek or
Realtek-Subsidiary Product (as defined below). For purposes of this Agreement, a
Realtek or Realtek-Subsidiary Product shall be a product designed by Realtek
and/or its Subsidiary, and sold by Realtek and/or its Subsidiary under a Realtek
and/or Realtek Subsidiary part number and/or with a Realtek and/or Realtek
Subsidiary topmark. For purposes of this Agreement, a part designed and sold by
Realtek and/or a Realtek Subsidiary using a part number requested by the customer
shall be considered sold by Realtek and/or a Realtek Subsidiary under a Realtek
and/or Realtek Subsidiary part number. For purposes of this Agreement,
Subsidiary shall mean a corporation, partnership or other legal entity in which
Realtek (x) owns a majority of the voting stock or other voting or controlling
interests, and (y) has effective management control.1.2
    
    The Realtek Group agrees to mark all Covered Products manufactured and sold at
all times in a manner consistent with 35 U.S.C. § 287. The Realtek Group may discharge
this duty, without limitation, by stamping or printing the U.S. patent numbers of the
Gigabit Patents on the Covered Products, or by stating in its associated software
license or on its associated packaging that the product is covered by one or more of
the Gigabit Patents, together with their applicable U.S. patent numbers. The Realtek
Group shall supply, upon reasonable request by 3Com, proof of marking of Covered
Products. Substantial ongoing failure to mark a Covered Product in an appropriate
manner shall void the licenses granted herein with respect to that Covered Product.1.3
    
    Subject to timely payment in full of the sums set forth in Section 2, 3Com
covenants not to sue Realtek, its Subsidiaries, its direct or indirect customers, or
its suppliers, for direct or indirect patent infringement under the Licensed Gigabit
Technology and U.S. Patent No. 6,526,446 (the 446 Patent) with respect to any
Covered Products or any other Realtek or Realtek-Subsidiary Products, or to assert the
Licensed Gigabit Technology and/or the 446 Patent to allege

infringement thereof as to Covered Products or any other Realtek or
Realtek-Subsidiary Products. In addition, pending the timely payment of the amounts
set forth in Section 2, 3Com covenants not to sue Realtek, its Subsidiaries, its
direct or indirect customers, or its suppliers, for direct or indirect patent
infringement under the Licensed Gigabit Technology and the 446 Patent with respect
to Covered Products or any other Realtek or Realtek-Subsidiary Products, or to
assert the Licensed Gigabit Technology and/or the 446 Patent to allege infringement
thereof as to Covered Products or any other Realtek or Realtek-Subsidiary Products,
until such payment is timely made.1.4
    
    Nothing contained in this Agreement will be construed as conferring by
implication, estoppel or otherwise, any license or other right under any patent rights
or other industrial or intellectual property rights of either Party in any jurisdiction
except for the licenses expressly granted herein. Nothing in this Agreement prevents
either Party from seeking any available remedies under patent law for any patent
infringement by the other Party when the Party does not have a license, covenant or
release with respect to that activity, including any remedies available under 35 U.S.C.
§§ 281, 283, 284 and 285.
 2.
    
    PAYMENT AND LICENSE FEES
 2.1
    
    In consideration for the licenses granted in Sections 1.1 and 1.3 above, the
Realtek Group shall pay to 3Com a license fee in the amount of USD $35,000,000.00,
representing royalties covering as stated in Sections 1.1 and 1.3 above. Payment of
the license fee shall be made by Amber Universal Inc. in full within 45 (forty-five)
days following the execution of this Agreement by wire transfer to an account to be
designated by 3Com.2.2
    
    Upon full payment of the license fee set forth in Section 2.1, the licenses
granted to the Realtek Group hereunder shall be fully paid-up and irrevocable. If the
license fee is not timely paid in full, this Agreement shall be null and void in its
entirety and its provisions shall have no effect.
