                         RESTATED STOCK OPTION AGREEMENT


         THIS RESTATED STOCK OPTION AGREEMENT, dated as of July 30, 1998, is
made between BET HOLDINGS II, INC. (the "Company") and Robert L. Johnson (the
"Optionee").

                                   WITNESSETH:

         WHEREAS, BET Holdings, Inc. has previously issued certain stock options
("Original Options") to the Optionee to purchase shares of Class A common stock
of BET Holdings, Inc.; and

         WHEREAS, the Company shall be the ultimate parent corporation in
connection with the Agreement and Plan of Merger among Robert L. Johnson,
Liberty Media Corporation, BTV Acquisition Corporation and BET Holdings, Inc.;
and

         WHEREAS, the Original Options previously issued to the Optionee by BET
Holdings, Inc. shall become options ("Company Options") to acquire Common Stock
("Common Stock") in the Company, as the ultimate parent of the corporate group
which previously included BET Holdings, Inc., pursuant to the terms and
conditions of this Restated Stock Option Agreement, it being the intention of
the parties to fully vest the Original Options, to cause the Options used to
restate such Original Options to have an initial value on the date of
restatement equal to the differential between (i) Sixty-Three Dollars ($63.00)
multiplied by the number of shares of Class A Common Stock which could otherwise
have been purchased pursuant to the exercise of such cancelled Original Options
and (ii) the aggregate exercise price attributable to all such cancelled
Original Options, and to allow the restatement of such Original Options into
Options hereunder in such manner as shall satisfy the requirements of Section
424(a) of the Internal Revenue Code of 1986, as amended.

         NOW, THEREFORE, in consideration of the premises and of the covenants
and agreements herein set forth, the parties mutually covenant and agree as
follows:

         1. Ratification of Outstanding Original Options. Pursuant to the
Agreement and Plan of Merger, options to purchase Two Hundred and Sixty-Two
Thousand (262,000) shares of the Class A common stock of BET Holdings, Inc. held
by the Eligible Executive which remain outstanding as of the date of the
transactions contemplated in the Agreement and Plan of Merger (the "Remaining
Options") shall, pursuant to this Agreement and Plan of Merger, remain
outstanding following the merger. Such Remaining Options, by virtue of the
merger and the reorganization transactions following the merger, shall
constitute Company Options to purchase Two Hundred and Sixty-Two Thousand
(262,000) shares of the Common Stock. The Company Options shall be deemed to
have been issued pursuant to the BET Holdings, Inc. 1991 Executive Stock Option
Plan, as amended and restated through July 30, 1998 into the BET Holdings II,
Inc. 1998 Executive Stock Option Plan (the "Plan"), the provisions of which are
hereby incorporated by reference. The Plan is hereby adopted and assumed by the
Company and the Company hereby assumes the obligations in respect of the Company
Options. The exercise price per share,
