Statement for Month/Year:                          04/2002

Explanation of Responses:

(1) The Reporting Person is filing this Form 4 because of the change in its
indirect ownership of the securities covered hereby (other than 125 shares of
Common Stock and the Series B Warrants, which are owned by a wholly owned
subsidiary of the Reporting Person) as a result of the transfer of Ascent
Entertainment Group, Inc., a wholly-owned subsidiary of the Reporting Person and
direct owner of such securities ("Ascent"), to a non-wholly-owned subsidiary of
the Reporting Person. This transaction may be deemed to constitute a reduction
in the Reporting Person's indirect pecuniary interest in such shares. On April
1, 2002, pursuant to a Purchase Agreement dated as of August 16, 2001, as
amended, by and among Liberty Satellite & Technology, Inc. ("LSAT"), the
Reporting Person, only for certain limited purposes, and another entity, all of
the shares of Ascent were transferred by the Reporting Person to LSAT. Following
this transaction, the Reporting Person is the owner of 84.1% of the outstanding
common stock of LSAT and 100% of LSAT's outstanding preferred stock, including
both convertible and nonconvertible preferred stock with an aggregate stated
value of $300 million.

(2) The Issuer is required to redeem all outstanding shares of Series D
Preferred Stock on June 30, 2011. At any time prior to that time and on or after
December 31, 2002, each share of Series D Preferred Stock, with a stated value
per share of $1,000, may be converted into 132.4503 fully paid and
non-assessable shares of Common Stock.

(3) Due to a clerical error, the Reporting Person had previously reported owning
39 Series B Warrants.
