PROSPECTUS

                                  $600,000,000

                           LIBERTY MEDIA CORPORATION              [LIBERTY LOGO]
                 3 1/2% SENIOR EXCHANGEABLE DEBENTURES DUE 2031
(Exchangeable for Motorola Inc. Common Stock or cash based on the value of that
                                     stock)

                             ---------------------

     This prospectus relates to $600,000,000 original principal amount of our
3 1/2% senior exchangeable debentures due 2031, which may be sold from time to
time by the selling security holders named herein.

     The debentures are exchangeable by the holders for the exchange market
value of the reference shares, calculated as described in this prospectus. The
reference shares currently consist of 36.8189 shares of Motorola Inc. common
stock per debenture.

     In addition to paying interest on the debentures, we will distribute, as an
additional distribution on each debenture, cash or securities (other than common
equity securities) that correspond to any dividends, distributions or other
payments made in respect of the reference shares. If any common equity
securities are distributed in respect of the reference shares, those securities
will themselves become reference shares.

     We may redeem the debentures at any time beginning on and after January 15,
2006, at the redemption prices described in this prospectus.

     The debentures were initially sold by us in a private placement to
qualified institutional buyers and pursuant to offers and sales that occurred
outside the United States in accordance with Regulation S under the Securities
Act of 1933. This prospectus has been made available to the selling security
holders in fulfillment of our obligations under a registration rights agreement.

     The selling security holders may offer and sell the debentures directly to
purchasers or through underwriters, brokers, dealers or agents, who may receive
compensation in the form of discounts, concessions or commissions. The
debentures may be sold in one or more transactions at fixed or negotiated prices
or at prices based on prevailing market prices at the time of sale.

     We will not receive any proceeds from the sale of the debentures by the
selling security holders. We are, however, responsible for the costs of
registering, under the Securities Act of 1933, the offer and sale of the
debentures by the selling security holders.

     INVESTING IN THE DEBENTURES INVOLVES RISKS.   SEE "RISK FACTORS" BEGINNING
ON PAGE 6.

                               PROSPECTUS SUMMARY

     The following summary highlights selected information from this prospectus
to help you understand Liberty and the debentures. For a more complete
understanding of Liberty and the debentures, we encourage you to read this
entire document, including the "Risk Factors" section, and all of the documents
that we incorporate by reference into this prospectus. All references to
"Liberty," "we," "us" and words to similar effect refer to Liberty Media
Corporation and, unless the context indicates otherwise, its consolidated
subsidiaries.

LIBERTY MEDIA CORPORATION

     We are a leading media, entertainment and communications company with
interests in a diverse group of public and private companies that are market
leaders in their respective industries. Our subsidiaries and business affiliates
are engaged in a broad range of programming, communications, technology and
Internet businesses and have some of the most recognized and respected brands.
These brands include Encore, STARZ!, Discovery, TV Guide, Fox, USA, QVC, CNN,
TBS, Motorola and Sprint PCS.

     Our management team, led by Dr. John C. Malone, our Chairman, and Mr.
Robert R. Bennett, our President and Chief Executive Officer, has extensive
expertise in creating and developing new businesses and opportunities for our
subsidiaries and business affiliates and in building scale, brand power and
market leadership. This expertise dates back to the mid-1980s when members of
our management were instrumental in identifying and executing strategic
transactions to provide TCI, our former parent, with quality programming for its
cable television systems. Today, our management team continues to leverage its
expertise and industry relationships on behalf of our subsidiaries and business
affiliates to identify and execute strategic transactions that improve the value
of their businesses and that allow us to take full advantage of new developments
in consumer and technological trends.

     The media, entertainment and communications industries are currently
undergoing tremendous changes due in part to the growth of new distribution
technologies, led by the Internet and the implementation of digital compression.
The growth in distribution technologies has, in turn, created strong demand for
an ever increasing array of multimedia products and services. We are working
with our subsidiaries and business affiliates to extend their established
brands, quality content and networks across multiple distribution platforms to
keep them at the forefront of these ongoing changes.

     The following table lists our principal subsidiaries and business
affiliates and our direct equity interests or indirect attributed equity
interests, based on ownership of capital stock. Our direct or attributed equity
interest in a particular company does not necessarily represent our voting
interest in that company. Our indirect attributed interest is determined by
multiplying our ownership interest in the holder of an equity interest by that
equity holder's ownership interest in the listed subsidiary or business
affiliate. The ownership percentages are approximate, calculated as of May 15,
2001, and, in the case of convertible securities we hold, assume conversion to
common stock by us and, to the extent known by us, other holders. In some cases
our interest is subject to buy/sell procedures, rights of first refusal or other
obligations.

BUSINESS STRATEGY

     Our business strategy is to maximize our value by (1) working with the
management teams of our existing subsidiaries and business affiliates to grow
their established businesses and create new businesses; (2) identifying and
executing strategic transactions that improve the value or optimize the
efficiency of our assets; and (3) managing our capital structure to maintain
liquidity, reduce risk and preserve a prudent debt structure. Key elements of
our business strategy include the following:

     - Promoting the internal growth of our subsidiaries and business
       affiliates;

     - Maintaining significant involvement in governance;

     - Participating with experienced management and strategic partners; and

     - Executing strategic transactions that optimize the efficiency of our
       assets; and

     - Participating in financial transactions to optimize our financial
       structure.

SPLIT OFF FROM AT&T CORP.

     We have been a subsidiary of AT&T Corp. since March 9, 1999. On that date,
AT&T acquired by merger our parent company, the former Tele-Communications,
Inc., which has since been converted into a limited liability company and
renamed AT&T Broadband, LLC. As part of that merger, AT&T issued AT&T common
stock (NYSE: T) and Class A and Class B Liberty Media Group common stock (NYSE:
LMG.A and LMG.B). AT&T's Liberty Media Group common stock is a tracking stock
designed to reflect the economic performance of the businesses and assets of
AT&T attributed to the "Liberty Media Group." We are included in the Liberty
Media Group, and our businesses and assets and those of our subsidiaries
constitute all of the businesses and assets of the Liberty Media Group.

     We have had a substantial degree of managerial autonomy from AT&T as a
result of our corporate governance arrangement with AT&T. Our board of directors
is controlled by persons designated by TCI prior to its acquisition by AT&T, and
our management consists of individuals who managed the businesses of Liberty
prior to the AT&T merger. We have entered into agreements with AT&T which
provide us with a level of financial and operational separation from AT&T,
define our rights and obligations as a member of AT&T's consolidated tax group,
enable us to finance our operations separately from those of AT&T and provide us
with certain programming rights with respect to AT&T's cable systems.

     On October 25, 2000, AT&T announced a restructuring of its businesses. In
this restructuring, we will be split off from AT&T, and we will become an
independent, publicly traded company. The split off is scheduled to occur at
9:00 a.m., New York City time, on August 10, 2001. In the split off, our common
stock will be recapitalized, and each outstanding share of AT&T Class A Liberty
Media Group tracking stock will be redeemed for one share of our new Series A
common stock, and each outstanding share of AT&T Class B Liberty Media Group
tracking stock will be redeemed for one share of our new Series B common stock.
Although we anticipate that the split off will occur as scheduled, the split off
is subject to certain conditions and we cannot assure you that it will be
consummated as currently contemplated or at all.

TERMS OF THE DEBENTURES

     On January 11, 2001 and January 17, 2001, we completed the private
placement of $600,000,000 aggregate principal amount of our 3 1/2% Senior
Exchangeable Debentures due 2031. On January 11, 2001, we entered into a
registration rights agreement with the initial purchaser, in which we agreed to
file for the benefit of the holders of the debentures a shelf registration
statement covering public resales of the debentures. This prospectus is part of
that shelf registration statement, and the debentures being offered hereby are
those initially sold by us in the private placement.

     Set forth below is a summary description of the terms of the debentures
being offered hereby. We refer you to "Description of the Debentures," beginning
on page 20, for a more complete description of the debentures.

Issuer..............................     Liberty Media Corporation

Debentures offered..................     $600,000,000 aggregate original
                                         principal amount of 3 1/2% Senior
                                         Exchangeable Debentures due 2031. The
                                         debentures are being offered by the
                                         selling security holders.

Ranking.............................     The debentures are our unsecured senior
                                         obligations and rank equally with all
                                         of our existing and future unsecured
                                         and unsubordinated obligations. As of
                                         March 31, 2001, we had approximately
                                         $4.0 billion of unsecured and
                                         unsubordinated indebtedness, all of
                                         which ranked equally with the
                                         debentures. The debentures will be
                                         effectively subordinated to all of our
                                         secured indebtedness to the extent of
                                         the value of the assets securing that
                                         indebtedness, and will be effectively
                                         subordinated to all liabilities of our
                                         consolidated subsidiaries. As of March
                                         31, 2001, we had approximately $315
                                         million of secured indebtedness and our
                                         consolidated subsidiaries had
                                         outstanding approximately $15.0 billion
                                         of liabilities, all of which
                                         effectively ranks senior to the
                                         debentures.

Denominations; Principal Amount.....     The minimum denomination is $1,000
                                         original principal amount, which we
                                         refer to as a debenture, and debentures
                                         may be transferred in integral
                                         multiples of $1,000 original principal
                                         amount. The principal amount of the
                                         debentures is subject to adjustment as
                                         described in this prospectus. Because
                                         the principal amount is subject to
                                         change, we refer to the principal
                                         amount, at any time of determination,
                                         as the adjusted principal amount.

Exchangeability.....................     At your option, each debenture can be
                                         exchanged for the exchange market
                                         value, calculated in the manner
                                         described in this prospectus, of the
                                         reference shares attributable to that
                                         debenture. At the date of this
                                         prospectus, the reference shares
                                         consist of 36.8189 shares of Motorola

                                         each debenture that you present for

Motorola and its Relationship to the
Debentures..........................     According to publicly available
                                         information, Motorola is a global
                                         leader in providing integrated
                                         communications solutions and embedded
                                         electronic solutions. Neither Motorola
                                         nor any other reference company will
                                         have any obligations whatsoever under
                                         the debentures. This prospectus relates
                                         solely to the debentures and does not
                                         relate to any offering of the Motorola
                                         stock or any other securities of
                                         Motorola or any successor reference
                                         company.

Maturity............................     The debentures have a stated maturity
                                         of January 15, 2031.

Interest............................     We will pay you interest at the rate of
                                         3 1/2% per annum on the original
                                         principal amount of the debentures.
                                         Interest will be paid semi-annually on
                                         each January 15 and July 15, beginning
                                         on July 15, 2001. The interest rate on
                                         the debentures is subject to increase
                                         (by up to an additional 1.00%) in the
                                         event this prospectus becomes unusable
                                         for more than 30 days in any
                                         twelve-month period.

Additional Distributions............     We will distribute, as an additional
                                         distribution on each debenture, (i)
                                         regular cash dividends on the reference
                                         shares in excess of the regular
                                         quarterly cash dividend of $0.04 per
                                         share currently being paid on the
                                         Motorola stock, and (ii) cash or
                                         securities (other than publicly traded
                                         common equity securities) that
                                         correspond to any other dividends,
                                         distributions or other payments made in
                                         respect of the reference shares. If any
                                         common equity securities are
                                         distributed in respect of the reference
                                         shares, those securities will
                                         themselves become reference shares.

                                         Any additional distribution that we pay
                                         as a result of a regular cash dividend
                                         on the reference shares in excess of
                                         the $0.04 per share quarterly cash
                                         dividend currently being paid by
                                         Motorola, which we refer to as an
                                         excess regular cash dividend amount,
                                         will be distributed to you with the
                                         next semi-annual interest payment on
                                         the debentures. All other additional
                                         distributions will be paid or made
                                         within 20 business days after the
                                         payment or delivery of the related
                                         dividends or distributions on the
                                         reference shares.

Adjusted Principal Amount...........     The adjusted principal amount of the
                                         debentures will not be reduced by any
                                         excess regular cash dividend amount
                                         that we distribute to holders of the
                                         debentures.

                                         The original principal amount of the
                                         debentures will be reduced by the
                                         amount of all additional distributions
                                         that we make to holders of the
                                         debentures that are attributable to
                                         extraordinary distributions on or in
                                         respect of the reference shares. The
                                         adjusted principal amount will also be
                                         reduced on subsequent interest payment
                                         dates to the extent necessary so that
                                         the annualized yield on the debentures
                                         paid by us does not exceed 3 1/2% per
                                         annum. In no event will the adjusted
                                         principal amount ever be less then
                                         zero. Reductions to the adjusted
                                         principal amount will not affect the
                                         amount of the semi-annual interest
                                         payment received by a holder of
                                         debentures, which is based on the
                                         original principal amount.

Optional Redemption.................     We may redeem the debentures, in whole
                                         or in part, at any time on or after
                                         January 15, 2006, at the redemption
                                         prices described herein. If we make a
                                         partial redemption, debentures with an
                                         aggregate principal amount of at least
                                         $100 million must remain outstanding.

Covenants...........................     The indenture governing the debentures
                                         contains covenants with respect to:

                                         - limitations on liens;

                                         - limitations on sale and leaseback;
                                           and

                                         - limitations on certain merger,
                                           consolidation and similar
                                           transactions. These covenants are
                                           subject to a number of important
                                           qualifications and exceptions. See
                                           "Description of the
                                           Debentures -- Certain Covenants."

Use of Proceeds.....................     We will not receive any of the proceeds
                                         from the secondary sale by the selling
                                         security holders of debentures. This
                                         prospectus fulfills an obligation of
                                         ours under a registration rights
                                         agreement that we entered into with the
                                         initial purchaser of the debentures.

Book-entry only.....................     The debentures have been issued in
                                         book-entry form and are represented by
                                         global debentures deposited with The
                                         Bank of New York on behalf of The
                                         Depository Trust Company. Except to the
                                         extent described herein, interests in
                                         the global debentures will be shown on,
                                         and transfers will be effected only
                                         through, records maintained by DTC and
                                         its participants.

RISK FACTORS

     An investment in the debentures involves risks.  See "Risk Factors"
beginning on the next page for a discussion of factors you should carefully
consider before deciding to purchase any debentures.

                                        5
   9

                                  RISK FACTORS

     An investment in the debentures involves risk.  You should carefully
consider the following factors, as well as the other information included in
this prospectus and in the documents we have incorporated by reference before
deciding to purchase the debentures. Any of the following risks could have a
material adverse effect on the value of the debentures.

FACTORS RELATING TO THE DEBENTURES

     The return to investors on the debentures depends on the value of the
Motorola stock.  The terms of the debentures differ from those of ordinary debt
securities because:

     - the effective yield on the debentures may change depending upon the
       dividend policy of Motorola or any other reference company;

     - the debentures are exchangeable by the holder for (1) cash in an amount
       based on the then exchange market value of the reference shares, (2) the
       reference shares themselves or (3) a combination of cash and reference
       shares, at the election of Liberty; and

     - the principal amount of the debentures will be reduced by the amount of
       an additional distribution that is made by Liberty following any
       extraordinary distribution being made on or in respect of the reference
       shares.

     Accordingly, the return that a holder of the debentures will realize may be
less than that of an ordinary fixed income debt security that may be issued by
us.

     We do not have any control over the dividend policy of Motorola. As of the
date of this prospectus, Motorola's stated dividend policy is to pay a quarterly
cash dividend of $0.04 per share on the Motorola stock. You will not receive an
additional distribution for regular quarterly cash dividends with respect to the
reference shares, except to the extent those dividends exceed Motorola's current
cash dividend. We cannot assure you that Motorola will increase its quarterly
dividend or that it will not reduce its quarterly dividend.

     It is not possible to predict whether the price of the Motorola stock will
rise or fall. Trading prices of the Motorola stock will be influenced by
Motorola's operating results and by complex and interrelated political,
economic, financial and other factors that can affect the capital markets
generally, the New York Stock Exchange and the market segments of which Motorola
is a part.

     Motorola has no obligations with respect to the debentures.  Motorola is
not involved in the offering of the debentures, and neither Motorola nor any
other reference company will have any obligations with respect to the
debentures, including any obligation to take our interests or your interests
into consideration for any reason or under any circumstance. Holders of the
debentures will not be entitled to any rights with respect to the Motorola stock
or any other reference shares other than indirectly pursuant to the express
terms of the debentures or at such time, if any, that the debentures are
tendered for exchange and we elect to deliver reference shares in connection
therewith.

     The number of reference shares attributable to the debentures will not
adjust for some dilutive transactions involving the reference shares.  If
specific dilutive or anti-dilutive events occur with respect to the reference
shares, the number and type of reference shares that will be used to calculate
the amount of cash or reference shares you will receive upon exchange, maturity
or redemption of a debenture will be adjusted to reflect such events. These
adjustments will not take into account various other events, such as offerings
of reference shares by a reference company for cash or business acquisitions by
a reference company with the reference shares, that may adversely affect the
price of the reference shares and may adversely affect the trading price and
market value of the debentures. We cannot assure you that a reference company
will not make offerings of the reference shares or other equity securities or
enter into such business acquisitions in the future.

     Purchasing the debentures involves potential adverse tax
consequences.  Before purchasing the debentures, you should recognize that the
amount of interest income required to be included in income by
                                        6
   10

you for each year will be in excess of the semi-annual interest payments you
actually receive. Any gain recognized by you on the sale or exchange of the
debentures will be ordinary income; any loss will be ordinary loss to the extent
of the interest previously included in income, and thereafter, capital loss. See
"Certain United States Federal Income Tax Considerations."

     The debentures are a recent issue of securities for which there is
currently no active trading market. The debentures are a recent issue of
securities with no active trading market. If a trading market does not develop
or is not maintained, holders of the debentures may experience difficulty in
reselling the debentures or may be unable to sell them at all. We cannot assure
you that an active public market or other market for the debentures will develop
or be maintained. If a market for the debentures develops, it may be
discontinued at any time.

     The liquidity of any market for the debentures will depend upon the number
of holders of the debentures, our operating performance, the operating
performance of Motorola or any other reference company, the interest of
securities dealers in making a market in the debentures and other factors. A
liquid trading market may not develop for the debentures. Furthermore, the
market price for the debentures may be subject to substantial fluctuations.
Factors such as the following may have a significant effect on the market price
of the debentures:

     - the market price of the Motorola stock or any other reference shares;

     - hedging or arbitrage trading activity that may develop involving the
       debentures and the Motorola stock or any other reference shares;

     - actual or anticipated fluctuations in our operating results;

     - our perceived business prospects;

     - general economic conditions, including prevailing interest rates; and

     - the market for similar securities.

FACTORS RELATING TO LIBERTY

     Our holding company structure could restrict access to funds of our
subsidiaries that may be needed to service the debentures.  Creditors of our
subsidiaries have a claim on their assets that is senior to that of holders of
the debentures. Liberty is a holding company with no significant assets other
than its equity interests in its subsidiaries and cash, cash equivalents and
marketable securities. Liberty is the only company obligated to make payments
under the debentures. Our subsidiaries are separate and distinct legal entities
and they have no obligation, contingent or otherwise, to pay any amounts due
under the debentures or to make any funds available for any of those payments.
In addition, neither AT&T nor any of its subsidiaries other than Liberty have
any obligation to make payments under the debentures or to make any funds
available for those payments.

     All of the liabilities of our subsidiaries effectively rank senior to the
debentures. A substantial portion of the consolidated liabilities of Liberty
consists of liabilities incurred by its subsidiaries. Moreover, the indenture
governing the debentures does not limit the amount of indebtedness that may be
incurred by Liberty's subsidiaries in the future. The rights of Liberty and of
its creditors, including holders of the debentures, to participate in the
distribution of assets of any subsidiary upon the latter's liquidation or
reorganization will be subject to prior claims of the subsidiary's creditors,
including trade creditors, except to the extent Liberty may itself be a creditor
with recognized claims against the subsidiary. Where Liberty is itself a
creditor of a subsidiary, its claims will still be subject to the prior claims
of any secured creditor of that subsidiary and to the claims of any holder of
indebtedness that is senior to the claim held by Liberty. As of March 31, 2001,
the aggregate amount of the total liabilities of our consolidated subsidiaries
was approximately $15.0 billion, of which approximately $10.9 billion was
deferred income taxes.

     We could be unable in the future to obtain a sufficient amount of cash with
which to service our financial obligations.  Our ability to meet our debt
service requirements, including those with respect to the

                                        7
   11

debentures, is dependent upon our ability to access cash. Liberty's sources of
cash include its available cash balances, net cash from the operating activities
of its subsidiaries, dividends and interest from its investments, availability
under credit facilities and proceeds from asset sales. Although at March 31,
2001, Liberty had cash and cash equivalents of approximately $2,089 million and
short-term investments of approximately $444 million, there is no requirement in
the indenture governing the debentures that any of Liberty's cash or cash
equivalents or proceeds from the sale of any of its marketable securities be
reserved for the payment of Liberty's obligations under the debentures. We
cannot assure you that Liberty will maintain significant amounts of cash, cash
equivalents or marketable securities in the future.

     Liberty obtained from its subsidiaries net cash of $7.5 million in the
first three months of 2001, $5 million in calendar year 2000 and $6 million in
calendar year 1999. The ability of Liberty's operating subsidiaries to pay
dividends or to make other payments or advances to Liberty depends on their
individual operating results and any statutory, regulatory or contractual
restrictions to which they may be or may become subject. Some of our
subsidiaries are subject to loan agreements that restrict sales of assets and
prohibit or limit the payment of dividends or the making of distributions, loans
or advances to stockholders and partners.

     Liberty generally does not receive cash, in the form of dividends, loans,
advances or otherwise, from its business affiliates (those companies in which
Liberty has less than a majority interest). In this regard, we do not have
voting control over most of our business affiliates and cannot cause those
companies to pay dividends or make other payments or advances to their partners
or shareholders (including us).

     AT&T has no obligation to provide financing for our operations and we do
not expect AT&T to provide us with any financing during the term of the
debentures. In addition, AT&T does not guarantee any of our indebtedness, and it
will have no obligations to the holders of the debentures in the event of a
payment default or other default by Liberty. Moreover, AT&T has publicly
announced the pending split off of Liberty. Please see "Prospectus
Summary -- Split Off from AT&T Corp." for information regarding the split off.

     We may secure future indebtedness of Liberty with the capital stock of our
subsidiaries or other securities, in which case that indebtedness will
effectively rank senior to the debentures.  The indenture does not restrict the
ability of Liberty to pledge shares of capital stock or other securities that it
owns to secure indebtedness. To the extent Liberty pledges shares of capital
stock or other securities to secure indebtedness, the indebtedness so secured
will effectively rank senior to the debentures to the extent of the value of the
shares or other securities pledged. The indenture also does not restrict the
ability of Liberty's subsidiaries to pledge shares of capital stock or other
assets that they own to secure indebtedness.

     We have entered into bank credit agreements that contain restrictions on
how we finance our operations and operate our business, which could impede our
ability to engage in transactions that would be beneficial for us.  Liberty and
its subsidiaries are subject to significant financial and operating restrictions
contained in outstanding credit facilities. These restrictions will affect, and
in some cases significantly limit or prohibit, among other things, our ability
or the ability of our subsidiaries to:

     - borrow more funds;

     - pay dividends or make other distributions;

     - make investments;

     - engage in transactions with affiliates; or

     - create liens.

                                        8
   12

     The restrictions contained in these credit agreements could have the
following adverse effects on us, among others:

     - we could be unable to obtain additional capital in the future to

        - fund capital expenditures or acquisitions that could improve the value
          of Liberty;

        - permit us to meet our loan and capital commitments to our business
          affiliates or allow us to help fund their operating losses or future
          development; or

        - allow us to conduct necessary corporate activities;

     - we could be unable to access the net cash of our subsidiaries to help
       meet our own financial obligations;

     - we could be unable to invest in companies in which we would otherwise
       invest; and

     - we could be unable to obtain lower borrowing costs that are available
       from secured lenders or engage in advantageous transactions that monetize
       our assets.

     In addition, some of the credit agreements to which our subsidiaries are a
party require them to maintain financial ratios, including ratios of total debt
to operating cash flow and operating cash flow to interest expense. If Liberty
or its subsidiaries fail to comply with the covenant restrictions contained in
their credit agreements, that could result in a default which accelerates the
maturity of the indebtedness borrowed pursuant to those agreements. Such a
default could also result in indebtedness under other credit agreements and the
debentures becoming due and payable due to the existence of cross-default or
cross-acceleration provisions of our credit agreements and in the indenture
governing the debentures.

     We have agreements with AT&T that restrict our ability to incur debt and
impede our ability to use AT&T Liberty Media Group tracking stock to effect
acquisitions or engage in other transactions.  Liberty has entered into an
Inter-Group Agreement with AT&T that restricts the amount of indebtedness that
Liberty may incur as a member of the Liberty Media Group. Under the Inter-Group
Agreement, no subsidiary of AT&T that is attributed to the Liberty Media Group
may incur any debt, other than the refinancing of debt without any increase in
amount, that would cause the total indebtedness of all the subsidiaries of AT&T
that are attributed to the Liberty Media Group at any time to be in excess of
25% of the total market capitalization of the Class A and Class B Liberty Media
Group tracking stock, unless the excess would not adversely affect the credit
rating of AT&T. To the extent we are unable to incur additional debt due to this
restriction, the effects set forth in the preceding risk factor arising out of
restrictions on our ability to borrow funds will be exacerbated. The AT&T
Liberty Media Group tracking stock is a common stock of AT&T, and we cannot use
that stock to effect acquisitions or for any other purpose without the prior
approval of the AT&T board of directors or of a three person capital stock
committee of the AT&T board of directors. Only one member of that committee, Dr.
John C. Malone, is also a director of Liberty. All of Liberty's common stock is
currently owned by a subsidiary of AT&T.

     Notwithstanding the foregoing, AT&T has publicly announced the pending
split off of Liberty, pursuant to which Liberty will cease to be a member of the
Liberty Media Group and will become an independent, publicly traded company. The
split off is, however, subject to certain conditions, and we cannot assure you
that the split off will occur as currently contemplated or at all.

     We may make significant capital contributions and loans to our subsidiaries
and business affiliates to cover operating losses and fund development and
growth, which could limit the amount of cash available to pay Liberty's own
financial obligations. The development of video programming, communications,
technology and Internet businesses involves substantial costs and capital
expenditures. As a result, many of our business affiliates have incurred
operating and net losses to date and are expected to continue to incur
significant losses for the foreseeable future. Our results of operations include
ours and our consolidated subsidiaries' share of the net losses of their
affiliates. The share of net losses amounted to $1,302 million for the first
three months of 2001, $3,485 million for the calendar year 2000 and $970 million
for calendar year 1999.

                                        9
   13

     We may make significant capital contributions and loans to our existing and
future subsidiaries and business affiliates to help cover their operating losses
and fund the development and growth of their respective businesses and
assets.  We have assisted, and may in the future assist, our subsidiaries and
business affiliates in their financing activities by guaranteeing bank and other
financial obligations. At March 31, 2001, we had guaranteed various loans, notes
payable, letters of credit and other obligations of certain of our subsidiaries
and business affiliates totaling $1,681 million.

     To the extent Liberty makes loans and capital contributions to its
subsidiaries and business affiliates or Liberty is required to expend cash due
to a default by a subsidiary or business affiliate of any obligation guaranteed
by Liberty, there will be that much less cash available to Liberty with which to
pay its own financial obligations, including the debentures.

     If we fail to meet required capital calls to a subsidiary or business
affiliate, we could be forced to sell our interest in that company, our interest
in that company could be diluted or we could forfeit important rights. We are
parties to shareholder and partnership agreements that provide for possible
capital calls on shareholders and partners. Our failure to meet a capital call,
or other commitment to provide capital or loans to a particular company, may
have adverse consequences to us. These consequences may include, among others,
the dilution of our equity interest in that company, the forfeiture of our right
to vote or exercise other rights, the right of the other shareholders or
partners to force us to sell our interest at less than fair value, the forced
dissolution of the company to which we have made the commitment or, in some
instances, a breach of contract action for damages against us. Our ability to
meet capital calls or other capital or loan commitments is subject to our
ability to access cash. See "-- We could be unable in the future to obtain a
sufficient amount of cash with which to service our financial obligations"
above.

     The liquidity and value of our interests in our business affiliates may be
adversely affected by shareholder agreements and similar agreements to which we
are a party.  A significant portion of the equity securities we own is held
pursuant to shareholder agreements, partnership agreements and other instruments
and agreements that contain provisions that affect the liquidity, and therefore
the realizable value, of those securities. Most of these agreements subject the
transfer of the stock, partnership or other interests constituting the equity
security to consent rights or rights of first refusal of the other shareholders
or partners. In certain cases, a change in control of Liberty or of the
subsidiary holding our equity interest will give rise to rights or remedies
exercisable by other shareholders or partners, such as a right to initiate or
require the initiation of buy/sell procedures. Our proposed split off from AT&T
will not be deemed a change of control event for these purposes. Some of our
subsidiaries and business affiliates are parties to loan agreements that
restrict changes in ownership of the borrower without the consent of the
lenders. All of these provisions will restrict our ability to sell those equity
securities and may adversely affect the price at which those securities may be
sold. For example, in the event buy/sell procedures are initiated at a time when
we are not in a financial position to buy the initiating party's interest, we
could be forced to sell our interest at a price based on the value established
by the initiating party, and that price might be significantly less than what we
might otherwise obtain.

     We do not have the right to manage our business affiliates, which means we
cannot cause those affiliates to operate in a manner that is favorable to
Liberty.  We do not have the right to manage the businesses or affairs of any of
our business affiliates in which we have less than a majority voting interest.
Rather, our rights, at most, may take the form of representation on the board of
directors or a partners' or similar committee that supervises management or
possession of veto rights over significant or extraordinary actions. The scope
of our veto rights varies from agreement to agreement. Although our board
representation and veto rights may enable us to prevent the sale by a business
affiliate in which we own less than a majority voting interest of assets or
prevent it from paying dividends or making distributions to its stockholders or
partners, they do not enable us to cause these actions to be taken.

     Our business is subject to risks of adverse government
regulation.  Programming services, cable television systems, satellite carriers,
television stations and internet companies are subject to varying degrees of
regulation in the United States by the Federal Communications Commission and
other entities. Such regulation and legislation are subject to the political
process and have been in constant flux over the past

                                        10
   14

decade. In addition, substantially every foreign country in which Liberty has,
or may in the future make, an investment regulates, in varying degrees, the
distribution and content of programming services and foreign investment in
programming companies and wireline and wireless cable communications, satellite,
telephony and Internet services. Further material changes in the law and
regulatory requirements must be anticipated, and there can be no assurance that
our business will not be adversely affected by future legislation, new
regulation or deregulation.

     We are subject to the risk of possibly becoming an investment
company.  Because Liberty is a holding company and a significant portion of its
assets consists of investments in companies in which Liberty owns less than a
50% interest, Liberty runs the risk of inadvertently becoming an investment
company that is required to register under the Investment Company Act of 1940.
Registered investment companies are subject to extensive, restrictive and
potentially adverse regulation relating to, among other things, operating
methods, management, capital structure, dividends and transactions with
affiliates. Registered investment companies are not permitted to operate their
business in the manner Liberty operates its business, nor are registered
investment companies permitted to have many of the relationships that Liberty
has with its affiliated companies.

     To avoid regulation under the Investment Company Act, Liberty monitors the
value of its investments and structures transactions with an eye toward the
Investment Company Act. As a result, Liberty may structure transactions in a
less advantageous manner than if Liberty did not have Investment Company Act
concerns, or Liberty may avoid otherwise economically desirable transactions due
to those concerns. In addition, events beyond Liberty's control, including
significant appreciation or depreciation in the market value of certain of our
publicly traded holdings, could result in us becoming an inadvertent investment
company. If we were to become an inadvertent investment company, we would have
one year to divest of a sufficient amount of investment securities and/or
acquire other assets sufficient to cause us to no longer be an investment
company.

     If it were established that Liberty is an unregistered investment company,
there would be a risk, among other material adverse consequences, that we could
become subject to monetary penalties or injunctive relief, or both, in an action
brought by the SEC, that we would be unable to enforce contracts with third
parties or that third parties could seek to obtain rescission of transactions
with us undertaken during the period it was established that we were an
unregistered investment company.

     We are dependent on a limited number of potential customers for carriage of
our programming services. The cable television and direct-to-home satellite
industries are currently undergoing a period of consolidation. As a result, the
number of potential buyers of our programming services and those of our business
affiliates is decreasing. AT&T's cable television subsidiaries and affiliates,
which as a group comprise one of the two largest operators of cable television
systems in the United States, are collectively the largest single customer of
Liberty's programming companies. With respect to some of our programming
services and those of our business affiliates, this is the case by a significant
margin. The existing agreements between AT&T's cable television subsidiaries and
affiliates and the program suppliers owned or affiliated with Liberty were
entered into prior to the AT&T merger. There can be no assurance that our owned
and affiliated program suppliers will be able to negotiate renewal agreements
with AT&T's cable television subsidiaries and affiliates. Although AT&T has
agreed to extend any existing affiliation agreement of Liberty and its
affiliates that expires on or before March 9, 2004 to a date not before March 9,
2009, that agreement is conditioned on mutual most favored nation terms being
offered and the arrangements being consistent with industry practice.

stock. In describing the debentures, the Motorola stock will initially comprise
the reference shares. As of the date of this prospectus, 36.8189 reference
shares are attributable to each debenture. The reference shares will also
include any other publicly traded common equity securities that may be
distributed on or in respect of the Motorola stock, or on or with respect to any
publicly traded common equity security into which any of those securities may be
converted or exchanged. In describing the debentures, we refer to Motorola and
any other company which may in the future become an issuer of reference shares
as the reference company.

     According to publicly available documents, Motorola is a global leader in
providing integrated communications solutions and embedded electronic solutions.
These include:

     - Software-enhanced wireless telephone, two-way radio and messaging

     Motorola is required to file reports and other information with the SEC.
Copies of these reports and other information may be inspected and copied at the
SEC offices specified under "Where to Find More Information" below.

     This prospectus relates only to the debentures and does not relate to the
Motorola stock or other securities of Motorola. Motorola has no obligations
whatsoever under the debentures. All disclosures contained in this prospectus
regarding Motorola are derived from the publicly available documents referred to
in the preceding paragraph. We have not participated in the preparation of
Motorola's documents nor made any due diligence inquiry with respect to the
information provided in those documents. The initial purchaser has not made any
due diligence inquiry with respect to the information provided in Motorola's
documents in connection with the offering of the debentures. Neither we nor the
initial purchaser represent that Motorola's publicly available documents or any
other publicly available information regarding Motorola are accurate or
complete. Neither we nor the initial purchaser can provide you with any
assurance that all events occurring prior to the date of this prospectus,
including events that would affect the accuracy or completeness of the publicly
available documents described in the preceding paragraph that would affect the
trading price of the Motorola stock, and therefore the issue price of the
debentures, have been publicly disclosed. Subsequent disclosure of any such
event or the disclosure of or failure to disclose material future events
concerning Motorola could affect the trading price of the debentures.

     We, our affiliates and the initial purchaser do not make any representation
to you as to the performance of Motorola, the Motorola stock or any other
securities of Motorola.

             PRICE RANGE AND DIVIDEND HISTORY OF THE MOTOROLA STOCK

     The Motorola stock is listed and traded on the NYSE under the symbol "MOT."

     The following table sets forth, for the calendar quarters indicated, the
range of high and low sale prices of the Motorola stock as reported on the NYSE
Composite Tape during the last two years. On June 1, 2000, Motorola effected a
3-for-1 common stock split in the form of a 200% dividend. The prices listed in
the table below have been adjusted to give effect to the stock split as if it
had occurred on January 1, 1999.

                            SELLING SECURITY HOLDERS

     We issued and sold the debentures in a private placement that was exempt
from the registration requirements of the Securities Act. We understand that the
initial purchaser of the debentures subsequently resold the debentures in
compliance with Rule 144A and Regulation S. Prior to the date of this
prospectus, the debentures were transferable in accordance with Rule 144A and
Regulation S and were eligible for trading in Nasdaq's Private Offerings,
Resales and Trading Through Automated Linkages (PORTAL) market. The selling
security holders listed below (including their transferees, pledgees, donees or
successors) may offer and sell pursuant to this prospectus any or all of the
debentures owned by them from time to time.

     In accordance with the terms of a registration rights agreement that we
entered into with the initial purchaser of the debentures, we have made this
prospectus available to the selling security holders so that they may publicly
resell their debentures.

     The following table sets forth information with respect to each selling
security holder and the principal amount of debentures owned by it. The entire
principal amount of the debentures owned by each of the selling security holders
named in the table may be sold pursuant to this prospectus. Because each selling
security holder may sell all or some of its debentures from time to time under
this prospectus, no estimate can be given at this time as to the principal
amount of debentures that will be held by a particular selling security holder
following any sale of debentures by it. In addition, some of the selling
security holders named in the table may have sold, transferred, loaned or
otherwise disposed of all or a portion of their debentures since the date they
last advised us of their holdings. Hence, the total principal amount of
debentures included in the following table does not equal the maximum aggregate
principal amount of debentures to which this prospectus relates. Changes in the
information concerning the selling security holders will be set forth in
supplements to this prospectus, when and if necessary.

                         DESCRIPTION OF THE DEBENTURES

     The debentures were issued under an indenture dated as of July 7, 1999,
between Liberty and The Bank of New York, as trustee, as supplemented by a fifth
supplemental indenture dated as of January 11, 2001, between Liberty and the
trustee. When we refer to the indenture, we mean the indenture as supplemented
by the fifth supplemental indenture. The terms of the debentures include those
stated in the indenture and those terms made part of the indenture by reference
to the Trust Indenture Act of 1939, as amended. The following summary of certain
provisions of the indenture and the debentures does not purport to be complete
and is subject to, and qualified in its entirety by reference to, the provisions
of the indenture. A copy of the indenture has been filed as an exhibit to the
registration statement of which this prospectus is a part. You can read the
indenture, and obtain a copy of it, at the locations described under "Where to
Find More Information."

GENERAL

     The indenture provides that senior debt securities may be issued by Liberty
thereunder from time to time in one or more series. The senior debt securities
that Liberty may issue under the indenture, including the debentures, are
collectively referred to in this section as the "senior debt securities." The
indenture does not limit the aggregate principal amount of senior debt
securities that may be issued under it. Senior debt securities of each series
issued under the indenture, including the debentures, may be reopened at any
time and additional securities of that series may be issued.

     The 3 1/2% senior exchangeable debentures due 2031 constitute a separate
series of senior debt securities under the indenture. The debentures are
unsecured senior obligations of Liberty and are initially limited to an
aggregate original principal amount of $600,000,000. They will mature on January
15, 2031, unless earlier exchanged by the holders or redeemed by Liberty. When
we refer to a "debenture" in this section, we are referring to a debenture in
the original principal amount of $1,000.

     The indenture does not contain any provision that restricts the ability of
Liberty to incur additional indebtedness. It also does not afford holders of
debentures any protection in the event of a decline in Liberty's credit quality
as a result of a takeover, recapitalization or similar transaction involving
Liberty. Subject to the limitations set forth under "-- Successor Corporation"
below, Liberty may enter into transactions, including a sale of all or
substantially all of its assets, a merger or a consolidation, that could
substantially increase the amount of Liberty's indebtedness or substantially
reduce or eliminate its assets, and which may have an adverse effect on
Liberty's ability to service its indebtedness, including the debentures.

     Liberty will make payments of principal, premium, if any, interest and
distributions on the debentures through the trustee to DTC, as the registered
holder of the debentures. See "-- Form, Denomination and Registration" below.
Liberty will not have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the global debentures registered in the name of DTC or its nominee,
or for maintaining, supervising or reviewing any records relating to those
beneficial ownership interests.

     If any payment or distribution on the debentures is to be made on a day
that is not a business day, that payment or distribution will be made on the
next business day, without interest or any other payment being made on account
of the delay. A business day means any day that is not a Saturday, Sunday or
legal holiday on which banking institutions or trust companies in The City of
New York are authorized or obligated by law or regulation to close.

     If the debentures at some date are reissued in certificated form, Liberty
will make payments of principal, premium, if any, interest and distributions on
the debentures to the registered holders thereof. Liberty will make payments due
on the maturity date in immediately available funds upon presentation and
surrender by the holder of a certificated debenture at the office or agency
maintained by Liberty for this purpose in the Borough of Manhattan, The City of
New York, which is expected to be the office of the trustee at 101 Barclay
Street, New York, N.Y. 10286. Liberty will pay interest and additional
distributions attributable to excess regular cash dividend amounts on the
reference shares, if any, due on a certificated debenture on

                                        20
   24

any interest payment date other than the maturity date by check mailed to the
address of the holder entitled to the payment as his address shall appear in the
security register of Liberty. Notwithstanding the foregoing, a holder of $10
million or more in aggregate original principal amount of certificated
debentures will be entitled to receive such payments, on any interest payment
date other than the maturity date, by wire transfer of immediately available
funds if appropriate wire transfer instructions have been received in writing by
the trustee not less than 15 calendar days prior to the interest payment date.
Any wire transfer instructions received by the trustee will remain in effect
until revoked by the holder. Any interest and any additional distribution due
and not punctually paid or duly provided for on a certificated debenture on any
interest payment date other than the maturity date will cease to be payable to
the holder of that debenture as of the close of business on the related record
date and may either be paid (1) to the person in whose name the certificated
debenture is registered at the close of business on a special record date for
the payment of the defaulted interest and any additional distribution that is
fixed by Liberty, written notice of which will be given to the holders of the
debentures not less than 30 calendar days prior to the special record date, or
(2) at any time in any other lawful manner.

     Liberty will pay or distribute additional distributions, if any, due on a
certificated debenture to the holder of that debenture as of a special record
date which will be the 10th business day after the date the related distribution
is made on the reference shares, at the address shown for such holder in the
security register of Liberty.

     All moneys or in-kind distributions paid or made by Liberty to the trustee
or any paying agent for the payment of principal, premium, if any, interest
and/or distributions on any certificated debenture which remain unclaimed for
two years after the payment or making thereof may be repaid or returned to
Liberty and, thereafter, the holder of the debenture may look only to Liberty
for payment.

RANKING AND HOLDING COMPANY STRUCTURE

     The debentures, which constitute unsecured senior indebtedness of Liberty,
rank equally with Liberty's existing and future unsubordinated unsecured
indebtedness, and senior in right of payment to all subordinated indebtedness of
Liberty. As of March 31, 2001, we had outstanding $4.0 billion of unsecured and
unsubordinated indebtedness, all of which ranks equally with the debentures. The
debentures are effectively subordinated to all secured indebtedness of Liberty,
to the extent of the value of the assets securing that indebtedness, and to all
liabilities of Liberty's subsidiaries. As of March 31, 2001, we had
approximately $315 million of secured indebtedness and our consolidated
subsidiaries had outstanding $15.0 billion of liabilities, all of which
effectively ranks senior to the debentures. See "Risk Factors -- Factors
Relating to Liberty -- Our holding company structure could restrict access to
funds of our subsidiaries that may be needed to service the debentures."

     Liberty is a holding company and is largely dependent on dividends,
distributions and other payments from its subsidiaries and business affiliates
and other investments to meet its financial obligations, and will be dependent
on those payments to meet its obligations under the debentures. Liberty's
subsidiaries and business affiliates, as well as AT&T and its subsidiaries other
than Liberty, have no obligation, contingent or otherwise, to pay any amounts
due under the debentures or to make any funds available for any of those
payments. See "Risk Factors -- Factors Relating to Liberty -- We could be unable
in the future to obtain a sufficient amount of cash with which to service our
financial obligations."

INTEREST

     Liberty will pay interest on the debentures semi-annually on January 15 and
July 15, beginning July 15, 2001, at the per annum rate of 3 1/2% of the
original principal amount of each debenture. The debentures will begin to accrue
interest on the date of original issuance of the debentures. Interest will be
paid to the persons in whose names the debentures are registered at the close of
business on the January 1 and July 1 preceding the interest payment date. We
refer to these dates as the regular payment dates. Changes in the adjusted
principal amount will not affect the amount of the semi-annual interest payments
received by holders of the debentures, which is calculated based solely on the
original principal amount. See "-- Adjusted Principal

                                        21
   25

Amount" below. Interest payable at maturity, or upon any earlier date of
redemption, will be payable to the person to whom principal shall be payable on
that date. Interest on the debentures is calculated on the basis of a 360-day
year of twelve 30-day months.

     Until a debenture can be transferred in compliance with Rule 144(k) under
the Securities Act, the interest rate on that debenture is subject to increase
in the event this prospectus becomes unusable by the selling security holders
for more than 30 days in any twelve-month period. Beginning on the 31st day, the
interest rate will increase by one quarter of one percent (0.25%) of the
original principal amount of the debenture for the first 90-day period
thereafter, and will increase by an additional one quarter of one percent of the
original principal amount of the debenture at the beginning of each subsequent
90-day period during which the prospectus remains unusable. However, the maximum
interest rate that may be borne by the debentures is 4 1/2%. Upon the prospectus
again becoming useable, the interest rate borne by the debentures will return to
the original interest rate of 3 1/2%.

EXCHANGE OPTION

     The holder of a debenture may at any time, except during the periods
described below under "-- Payment at Stated Maturity" and "-- Redemption,"
exchange the debenture for the exchange market value of the reference shares
attributable to that debenture. Liberty may pay the exchange market value of
each debenture tendered for exchange as follows:

     - in cash;

     - by delivering the reference shares attributable to the debenture; or

     - in a combination of cash and reference shares.

     For so long as the debentures are represented by global debentures
registered in the name of DTC or its nominee, exchanges may be effected only
through DTC's Automated Tender Offer Program, or ATOP. If the debentures at some
date are reissued in certificated form, the exchange right at that time will be
exercisable as follows:

     - by completing and manually signing an exchange notice in the form
       available from the exchange agent, which is initially the trustee, and
       delivering the exchange notice to the exchange agent at the office it
       maintains for this purpose;

     - by surrendering the debentures to be exchanged to the exchange agent;

     - if required, by furnishing appropriate endorsement and transfer
       documents; and

     - if required, by paying all transfer or similar taxes.

     If an exchange is made during the period between a regular record date and
the next succeeding interest payment date, the exchanging holder will be
required to tender funds equal to the interest and any additional distribution
that is payable to the holders of debentures on that interest payment date.

     We refer to the date on which all of the foregoing requirements for
exchange of a particular debenture are satisfied as the exchange date for that
debenture. The transmission of an agent's message requesting an exchange through
ATOP, or delivery of an exchange notice to the exchange agent, shall be
irrevocable. Liberty will advise a holder that tenders debentures for exchange
of the form of consideration to be paid by Liberty for the exchange market value
of the reference shares attributable to the debentures by 9:30 a.m., New York
City time, on the first trading day after the exchange date. Such advice by
Liberty shall be irrevocable.

     At the date of this prospectus, the reference shares attributable to each
debenture consist of 36.8189 shares of Motorola stock. If any other publicly
traded common equity securities, including additional shares of Motorola stock,
are issued as a distribution in respect of the Motorola stock or any other
reference shares, or if any reference shares are exchanged for publicly traded
common equity securities of a different

                                        22
   26

issuer in an exchange offer, merger or other extraordinary transaction, then the
reference shares will include the shares so issued, or be replaced by the shares
issued in the exchange offer, merger or other transaction. See "-- Changes to
the Reference Shares" below.

     We will pay the consideration due upon an exchange of debentures as soon as
reasonably practicable after the determination of the exchange market value, but
in no event later than 10 trading days thereafter. The calculation of the
exchange market value of a debenture will depend on when the notice of exchange
for that debenture is delivered to the exchange agent. If the notice is
delivered before January 15, 2002, the exchange market value will be the closing
price of the reference shares attributable to that debenture on the twentieth
trading day following its exchange date, unless the exchange agent receives
notices of exchange for more than $1,000,000 aggregate original principal amount
of debentures on the same day, in which case the exchange market value of those
debentures will be the average of the closing prices of the reference shares on
the five trading days ending on the twentieth trading day following the exchange
date.

     If the notice of exchange for a debenture is delivered on or after January
15, 2002, the exchange market value will be the closing price of the reference
shares attributable to that debenture on the trading day following its exchange
date, unless the exchange agent receives notices of exchange for more than
$1,000,000 aggregate original principal amount of debentures on the same day, in
which case the exchange market value of those debentures will be the average of
the closing prices of the reference shares on the five trading days following
the exchange date.

     If more than $1,000,000 aggregate original principal amount of debentures
are tendered for exchange on any day, notice of that event will be given to DTC
for dissemination through the DTC broadcast facility. Our failure to provide
this notice, however, will not affect the determination of the exchange market
value of the debentures tendered for exchange.

     The closing price of a security on any date means:

     - the closing sale price or, if no closing sale price is reported, the last
       reported sale price, of that security (regular way) on the NYSE; or

     - if the security is not listed for trading on the NYSE, as reported in the
       composite transactions for the principal United States national or
       regional securities exchange on which it is listed; or

     - if the security is not listed on a United States national or regional
       securities exchange, as reported by the Nasdaq National Market, or if the
       security is not so reported, the last quoted bid price for the security
       in the over-the-counter market as reported by the National Quotation
       Bureau or a similar organization.

     If the closing price of a security cannot be determined by any of the
foregoing methods on a particular trading day, our board of directors will be
entitled to determine the closing price on the basis of those quotations that
it, in good faith, considers appropriate. However, a nationally recognized
investment banking or appraisal firm retained by us will make that determination
if the securities at issue are to be distributed to holders of the debentures
and the aggregate value of those securities is expected to exceed $100,000,000.
With respect to options, warrants, and other rights to purchase a security, the
closing price of the option, warrant or other right will be deemed to be the
closing price of the underlying security, minus the exercise price. With respect
to securities exchangeable for or convertible into another security, the closing
price of the exchangeable or convertible security will be the closing price of
that security determined as aforesaid or, if its closing price cannot be so
determined, then the closing price will be deemed to be the fully exchanged or
converted value based upon the closing price of the underlying security. If an
"ex-dividend" date for a security occurs during the period used in determining
that security's closing price, the closing price of the security on any day
prior to the "ex-dividend" date used in calculating the closing price shall be
reduced by the amount of the dividend. For this purpose, the amount of a
non-cash dividend will be equal to the value of that dividend as determined by a
nationally recognized investment banking firm that we retain for this purpose.

                                        23
   27

ADDITIONAL DISTRIBUTIONS

     If a reference company pays or makes a dividend or distribution on its
reference shares, we may pay or make an additional distribution to holders of
the debentures based on that dividend or distribution. At the date of this
prospectus, the reference shares attributable to each debenture consist of
36.8189 shares of Motorola stock, and Motorola is the initial reference company.
The reference shares and the reference company are subject to change as
described under "-- Changes to the Reference Shares" below.

     As of the date of this prospectus, Motorola's stated dividend policy is to
pay a regular quarterly cash dividend of $0.04 per share on the Motorola stock.
This amounts to an aggregate $1.4727 in respect of the number of reference
shares initially attributable to each debenture, which we refer to as the
regular cash dividend retention amount. Any regular cash dividend that is paid
in respect of the number of reference shares attributable to each debenture on
such payment date that does not exceed the regular cash dividend retention
amount will not be distributed to holders of the debentures. We will, however,
pay to the holder of each debenture, as an additional distribution, the amount
of any regular cash dividend paid in respect of the number of reference shares
attributable to each debenture to the extent (but only to the extent) that
dividend exceeds the regular cash dividend retention amount. We refer to the
portion of any regular cash dividend in respect of the number of reference
shares attributable to each debenture that exceeds the regular cash dividend
retention amount as the excess regular cash dividend amount. We will pay this
additional distribution on the next semi-annual interest payment date for the
debentures. The additional distribution will be paid to holders of the
debentures as of 5:00 p.m., New York City time, on the regular record date for
that interest payment date. We will treat as a regular cash dividend any cash
dividend that is paid by a reference company in accordance with its publicly
announced regular common equity dividend policy. We refer to any dividend or
distribution by a reference company on its reference shares that is not a
regular cash dividend as an extraordinary distribution.

     Whether and what we pay or make by way of an additional distribution
following an extraordinary distribution by a reference company on its reference
shares will depend on the nature of the extraordinary distribution. If an
extraordinary distribution consists of cash, we will pay to holders of the
debentures, as an additional distribution on each debenture, the amount of the
cash distribution received by a holder of the number of reference shares
attributable to a debenture.

     If an extraordinary distribution consists of publicly traded common equity
securities, we will not make an additional distribution to holders of the
debentures. Rather, the number of publicly traded common equity securities
(including fractions thereof) distributed to a holder of the number of reference
shares attributable to a debenture will be treated as reference shares that are
also attributable to that debenture.

     If an extraordinary distribution consists of publicly traded securities
other than common equity securities, including options, warrants or similar
rights to acquire reference shares, we will cause to be delivered to the holders
of the debentures, as an additional distribution on each debenture, those
securities received by a holder of the number of reference shares attributable
to a debenture. We will not, however, deliver fractional securities. Instead, we
will pay cash in an amount equal to the product of the fractional interest times
the closing price of the security as of the special record date we set for the
additional distribution. If Liberty is unable to distribute any securities as an
additional distribution because necessary qualifications or registrations under
applicable state or federal laws cannot be obtained on a timely basis, then the
additional distribution may instead consist of cash. The cash payment will be
based on the average, over the five trading days ending on the trading day next
preceding the date the additional distribution is paid, of the closing prices of
the security that would have otherwise been delivered.

     If an extraordinary distribution consists of assets or property other than
cash or publicly traded securities, we will pay to holders of the debentures, as
an additional distribution on each debenture, an amount of cash equal to the
fair market value of the assets or properties distributed to a holder of the
number of reference shares attributable to a debenture. That fair market value
will be determined, in good faith, by our board of directors. However, a
nationally recognized investment banking or appraisal firm retained by us will
make that determination if we expect the aggregate fair market value of the
assets or properties distributed on the number of reference shares attributable
to all of the outstanding debentures to exceed $100,000,000.
                                        24
   28

     We will treat as an extraordinary distribution any consideration that is
distributed in connection with a merger, consolidation, share exchange,
liquidation or dissolution involving a reference company, except to the extent
it consists of publicly traded common equity securities. Publicly traded common
equity securities that are issued in connection with a merger, consolidation,
share exchange, liquidation or dissolution involving a reference company will
themselves become reference shares. See "-- Changes to the Reference Shares"
below.

     We will make an additional distribution that is attributable to an
extraordinary distribution on the twentieth business day after such
extraordinary distribution is made by the applicable reference company or
successor reference company. The additional distribution will be paid to holders
of the debentures as of a special record date that will be the tenth business
day prior to the date we pay the additional distribution.

     Liberty will issue a press release setting forth the amount and
composition, per debenture, of any additional distribution to be made by it that
is attributable to an extraordinary distribution, and will deliver such release
to DTC for dissemination through the DTC broadcast facility. All additional
distributions that are paid or made in respect of any excess regular cash
dividend amount or extraordinary distributions will be paid or made without any
interest or other payment in respect of such amounts.

ADJUSTED PRINCIPAL AMOUNT

     Original Principal Amount.  The principal amount of the debentures
initially is equal to their original principal amount, which is $1,000 for each
debenture.

     Adjustments to Principal Amount.  The principal amount of the debentures
will be adjusted downward to reflect any additional distributions that we make
to holders of the debentures that are attributable to extraordinary
distributions made on the reference shares. No adjustment will be made to the
principal amount, however, for additional distributions that are paid in respect
of any excess regular cash dividend amount. Because the principal amount of the
debentures is subject to reduction, we refer to the principal amount of a
debenture at any time as its adjusted principal amount. In no event will the
adjusted principal amount of a debenture be less than zero.

     On any date that we pay or make an additional distribution to the holders
of the debentures that is attributable to an extraordinary distribution on the
reference shares, the original principal amount of each debenture (or, if such
principal amount has previously been reduced, the adjusted principal amount of
the debenture) will be reduced by the amount of the additional distribution that
is paid or made with respect to that debenture. Thereafter, the adjusted
principal amount will be further reduced on each successive semi-annual interest
payment date to the extent necessary to cause the semi-annual interest payment
on that date to represent the payment by Liberty, in arrears, of an annualized
yield of 3 1/2% of the adjusted principal amount of the debentures. An
adjustment for purposes of ensuring that Liberty does not pay an annualized
yield of more than 3 1/2% of the adjusted principal amount of the debentures
that is necessitated by the payment of an additional distribution to holders of
the debentures will take effect on the second succeeding interest payment date
after the payment of that distribution. We will issue a press release, and
provide the release to DTC for dissemination through the DTC broadcast facility,
each time an adjustment is made to the adjusted principal amount of the
debentures.

     The adjustments described above will not affect the amount of the
semi-annual interest payments received by holders of debentures, which will
continue to be a rate of interest equal to 3 1/2% per annum of the original
principal amount of the debentures.

                                        25
   29

PAYMENT AT STATED MATURITY

     The stated maturity of the debentures is January 15, 2031. The amount that
we will pay a holder of debentures at stated maturity will depend on whether we
notify holders, not less than 30 business days prior to the stated maturity
date:

     - that we will cause reference shares to be delivered in payment of the
       exchange market value of all debentures tendered for exchange up until
       the close of business on the trading day preceding the stated maturity
       date; or

     - that we are terminating, as of the 30th business day prior to the stated
       maturity date, the right of all holders to exchange their debentures for
       the exchange market value thereof.

     Continuation of Exchange Right.  If we notify debenture holders that we
will cause reference shares to be delivered in payment of the exchange market
value of all debentures tendered for exchange up until the close of business on
the trading day preceding the stated maturity date, then we will pay, for each
debenture outstanding on the stated maturity date, an amount equal to the sum
of:

     - the adjusted principal amount of the debenture; plus

     - any accrued but unpaid interest on the debenture up to the stated
       maturity date; plus

     - any final period distribution on the debenture.

     Termination of Exchange Right.  If we notify debenture holders that we are
terminating, as of the 30th business day prior to the stated maturity date,
their right to exchange their debentures for the exchange market value thereof,
then we will pay, for each debenture outstanding on the stated maturity date, an
amount equal to the sum of:

     - the greater of:

     - the adjusted principal amount of the debenture; and

     - the current market value of the reference shares attributable to the
       debenture; plus

     - any accrued but unpaid interest on the debenture up to the stated
       maturity date; plus

     - any final period distribution on the debenture.

     The current market value of the reference shares attributable to the
debentures for this purpose will be calculated based on the average closing
price for each reference share over the 20 trading day period immediately prior
to, but not including, the fifth business day preceding the stated maturity
date.

     A final period distribution will be made if, as of the stated maturity
date:

     - a regular cash dividend that includes an excess regular cash dividend
       amount has been declared on any of the reference shares attributable to a
       debenture or an extraordinary dividend has been declared on any of the
       reference shares attributable to a debenture; and

     - the ex-dividend date for that dividend or distribution has occurred; and

     - the holders of such reference shares have not yet received the dividend
       or distribution.

     In the case of a regular cash dividend that includes an excess regular cash
dividend amount that has been declared on reference shares attributable to a
debenture as of the stated maturity date but not yet paid, the final period
distribution for each debenture will be equal to the amount of the excess
regular cash dividend amount that is payable to a holder of the number of
reference shares attributable to a debenture. This amount will be paid on the
stated maturity date with all other amounts then due. In the case of an
extraordinary distribution that has been declared on reference shares as of the
stated maturity date but not yet paid or made, the form and amount of the final
period distribution will be determined in the same manner as that for an

                                        26
   30

additional distribution that would have been attributable to that extraordinary
distribution, except that any publicly traded common equity securities to be
distributed on the reference shares will be part of any final period
distribution rather than treated as additional reference shares. Because any
additional distribution we make on a debenture that is attributable to an
extraordinary distribution on the reference shares is deducted from the adjusted
principal amount of that debenture, we will deduct from any final period
distribution that is attributable to an extraordinary distribution the adjusted
principal amount of the debenture, as of the stated maturity date, as to which
such final period distribution is paid. We will pay or make any final period
distribution that is attributable to an extraordinary distribution on the 20th
business day after the payment of that extraordinary dividend by the applicable
reference company.

     The amount we pay for any debentures outstanding on the stated maturity
date will be payable in cash, except that any final period distribution included
in that amount which consists of publicly traded securities will be payable by
delivery of those securities.

AMOUNT PAYABLE UPON ACCELERATION OF THE DEBENTURES

     If the maturity of the debentures is accelerated following an event of
default, the amount payable for each debenture will be determined in the same
manner as the amount payable at stated maturity under the circumstances in which
Liberty notifies debenture holders that it is terminating, as of the 30th
business day prior to the stated maturity date, their right to exchange their
debentures for the exchange market value thereof. See "-- Payment at Stated
Maturity" above.

REDEMPTION

     Optional Redemption.  The debentures are not redeemable before January 15,
2006. At any time or from time to time on or after January 15, 2006, Liberty may
redeem all or some of the debentures on not less than 30 business days prior
notice. If Liberty chooses to redeem only some of the debentures, there must
remain outstanding, immediately following any partial redemption, at least $100
million original principal amount of debentures.

     The redemption price we pay for a debenture on any redemption date will
depend on whether we notify holders of debentures called for redemption, not
less than 30 business days prior to the redemption date:

     - that we will cause reference shares to be delivered in payment of the
       exchange market value of all debentures called for redemption that are
       tendered for exchange up until the close of business on the trading day
       next preceding the redemption date; or

     - that we are terminating, as of the 30th business day prior to the
       redemption date, the right of all holders of debentures called for
       redemption to exchange those debentures for the exchange market value
       thereof.

     Any termination of the exchange right in the event of a partial redemption
will only apply to the debentures called for redemption.

     Continuation of Exchange Right.  If we notify debenture holders that we
will cause reference shares to be delivered in payment of the exchange market
value of all debentures called for redemption that are tendered for exchange up
until the close of business on the trading day next preceding the redemption
date, then we will pay, for each debenture that we redeem on the redemption
date, a redemption price equal to the sum of:

     - the adjusted principal amount of the debenture; plus

     - any accrued but unpaid interest on the debenture up to the redemption
       date; plus

     - any final period distribution on the debenture.

     Termination of Exchange Right.  If we notify holders of debentures called
for redemption that we are terminating, as of the 30th business day prior to the
redemption date, their right to exchange their debentures
                                        27
   31

for the exchange market value thereof, then we will pay, for each debenture that
we redeem on the redemption date, an amount equal to the sum of:

     - the greater of:

     - the adjusted principal amount of the debenture; and

     - the current market value of the reference shares attributable to the
       debenture; plus

     - any accrued but unpaid interest on the debenture up to the redemption
       date; plus

     - any final period distribution on the debenture.

     Calculation of Current Market Value.  If the current market value of the
reference shares attributable to a debenture needs to be calculated to determine
the amount of the redemption price, it will be calculated based on the average
closing price for each reference share over the 20 trading day period
immediately prior to, but not including, the fifth business day preceding the
redemption date.

     Definition and Timing of Final Period Distribution.  A final period
distribution will be made with respect to each debenture we redeem if, as of the
redemption date:

     - a regular cash dividend that includes an excess regular cash dividend
       amount has been declared on any of the reference shares attributable to a
       debenture or an extraordinary dividend has been declared on any of the
       reference shares attributable to a debenture; and

     - the ex-dividend date for that dividend or distribution has occurred; and

     - the holders of such reference shares have not yet received the dividend
       or distribution.

     The timing, amount and form of any final period distribution that we make
in connection with a redemption of debentures will be determined in the same
manner as that described under "-- Payment at Stated Maturity" above for any
final distribution we may make in connection with the repayment of debentures
that are outstanding on the stated maturity date.

     Payment of Redemption Price.  The redemption price will be paid in cash,
except that any final period distribution included in the redemption price which
consists of publicly traded common equity securities will be payable by delivery
of those securities. On or prior to the redemption date, we will irrevocably
deposit with the trustee sufficient funds to pay the redemption price for all
debentures being redeemed at that date, other than any final period distribution
that is attributable to an extraordinary distribution on the reference shares. A
final period distribution that is attributable to an extraordinary distribution
will be paid on the 20th business day after the extraordinary distribution is
received by holders of reference shares. If the redemption date is not a
business day, then the redemption price will be payable on the next business
day, without any interest or other payment being made in respect of the delay.

     Additional distributions to be made after debentures have been called for
redemption and before the redemption date will be payable to the holders on the
record date for that distribution.

     Once a notice of redemption is given and funds are irrevocably deposited,
interest on the debentures will cease to accrue on and after the date of
redemption and all rights of the holders of the debentures will cease, except
for the right of the holders to receive the redemption amount, including, if
applicable, any final period distribution (but without any interest or other
payment on that redemption amount).

     If we improperly withhold or refuse to pay the redemption price for the
debentures, interest on the debentures will continue to accrue at an annual rate
of 3 1/2% from the original redemption date to the actual date of payment. In
this case, the actual payment date will be considered the redemption date for
purposes of calculating the redemption price. Any final period distribution will
be payable based on the original redemption date scheduled.

                                        28
   32

     In compliance with applicable law (including the United States federal
securities laws), we and our affiliates may, at any time, purchase outstanding
debentures by tender, in the open market or by private agreement.

CHANGES TO THE REFERENCE SHARES

     As of the date of this prospectus, Motorola is the reference company and
one share of Motorola stock represents one reference share. The reference
company may change over the 30-year term of the debentures, or there may be one
or more additional reference companies. A change in, or the addition of, a
reference company will result in a change in, or the addition to, the reference
shares attributable to the debentures. One reference share attributable to each
debenture may, over time, consist of a basket of reference shares.

     The initial reference shares attributable to each debenture are 36.8189
shares of Motorola stock.

     The reference shares attributable to each debenture will be affected by the
following events, in the manner described below:

     Dividends and Distributions.  If a reference company makes a dividend or
distribution on its reference shares consisting of additional reference shares
of the same class, then the number of reference shares attributable to each
debenture will equal the sum of:

     - the number of reference shares attributable to each debenture immediately
       prior to the dividend or distribution; and

     - the number of additional references shares that a holder of the number of
       reference shares attributable to each debenture receives as a result of
       the dividend or distribution.

     If a reference company makes a distribution on its reference shares
consisting of publicly traded common equity securities of another class of that
reference company or of another issuer, then the reference shares attributable
to each debenture will consist of the following:

     - the number of reference shares attributable to each debenture immediately
       prior to the distribution; and

     - the number and type of new common equity securities that a holder of the
       number of reference shares attributable to each debenture receives as a
       result of the distribution.

     Any change in the reference shares attributable to a debenture that results
from a dividend or distribution by a reference company will be deemed to have
occurred on the date the dividend or distribution is made by the reference
company.

     Combinations, Subdivisions and Reclassifications.  If a reference company
combines or subdivides its reference shares or issues by reclassification of its
reference shares any shares of any other class of its publicly traded common
equity securities (including any reclassification that is effected in connection
with a merger in which the reference company is the continuing corporation), the
reference shares will be adjusted so that the reference shares attributable to
each debenture will become the number and kind of reference shares that a holder
of the reference shares attributable to each debenture immediately prior to the
combination, subdivision or reclassification owns immediately following that
action.

     Any change in the reference shares attributable to a debenture that results
from a combination, split or reclassification by a reference company will be
deemed to have occurred immediately after the effective date of the combination,
subdivision or reclassification.

     Mergers and Consolidations.  If a reference company merges or consolidates
with another company where the reference shares are exchanged for other publicly
traded common equity securities, the reference shares will be adjusted so that
the reference shares attributable to each debenture will become the number and
kind of publicly traded common equity securities that a holder of the number of
reference shares attributable to each debenture immediately prior to the merger
or consolidation owns immediately following the merger or consolidation. To the
extent the consideration received by the holders of reference shares in a merger
or

                                        29
   33

consolidation consists of cash or assets other than publicly traded common
equity securities, the cash and assets so received will be treated as though
they were part of an extraordinary distribution by the reference company or the
successor reference company, and shall be the object of an additional
distribution by Liberty. See "-- Additional Distributions" above.

     If an election is offered to holders of reference shares as to the form of
consideration they may receive in any merger or consolidation, such election
shall be deemed a reference share offer and treated in the manner described
under "-- Tender or Exchange Offer; Elections" below.

     Any change in the reference shares attributable to a debenture that results
from a merger or consolidation will be deemed to have occurred immediately after
the effective date of the merger or consolidation.

     Statutory Share Exchange.  If a reference company participates in a
statutory share exchange with another company where the reference shares are
exchanged for other publicly traded common equity securities, the reference
shares will be adjusted so that the reference shares attributable to each
debenture will become the number and kind of publicly traded common equity
securities that a holder of the number of reference shares attributable to each
debenture immediately prior to the share exchange owns immediately following the
share exchange. To the extent the consideration received by the holders of
reference shares in a share exchange consists of cash or assets other than
publicly traded common equity securities, the cash and assets so exchanged will
be treated as though they were part of an extraordinary distribution by the
reference company or the successor reference company, and shall be the object of
an additional distribution by Liberty. See "-- Additional Distributions" above.

     If an election is offered to holders of reference shares as to the form of
consideration they may receive in any statutory exchange, such election shall be
deemed a reference share offer and treated in the manner described under
"-- Tender or Exchange Offer; Elections" below.

     Any change in the reference shares attributable to a debenture that results
from a share exchange will be deemed to have occurred immediately after the
effective date of the share exchange.

     Liquidation or Dissolution.  If a reference company liquidates or
dissolves, the reference shares will be adjusted so that the reference shares
attributable to each debenture will become the number and kind of publicly
traded common equity securities, if any, that a holder of the number of
reference shares attributable to each debenture immediately prior to the
liquidation or dissolution owns immediately thereafter. To the extent the
consideration received by the holders of reference shares in a liquidation or
dissolution consists of cash or assets other than publicly traded common equity
securities, the cash and assets so exchanged will be treated as though they were
part of an extraordinary distribution by the reference company, and shall be the
subject of an additional distribution by Liberty. See "-- Additional
Distributions" above.

     Any change in the reference shares attributable to a debenture that results
from the liquidation or dissolution of a reference company will be deemed to
have occurred immediately after the effective date of the liquidation or
dissolution.

     Tender or Exchange Offer; Elections.  The reference shares will be adjusted
in the event of any tender or exchange offer for 30% or more of the outstanding
reference shares of any reference company. In the event of such a tender offer,
or any consolidation, merger or statutory share exchange involving a reference
company in which an election is given to holders of reference shares as to the
consideration to be received in the transaction, a reference share offer shall
be deemed to have been made.

     If a reference share offer is made, we will make a reference share offer
adjustment. This means the reference shares attributable to each debenture will
include, immediately after the closing of the reference share offer, the portion
of the average transaction consideration that consists of publicly traded common
equity securities. In addition, this means reducing the reference shares
attributable to each debenture immediately prior to the closing of such
reference share offer by the reference share proportionate reduction.

     The term "average transaction consideration" means, as to each reference
share subject to the reference share offer, the quotient derived by dividing (1)
the aggregate amount of consideration actually distributed or paid to all
holders of reference shares that participated in the reference share offer, by
(2) the total number of
                                        30
   34

reference shares outstanding immediately prior to the closing of the reference
share offer and entitled to participate in that reference share offer.

     The term "reference share proportionate reduction" means a proportionate
reduction in the number of reference shares attributable to each debenture that
are the subject of the reference share offer, calculated in accordance with the
following formula:

     R = X/N

     where:

     R = the fraction by which the number of reference shares that are the
     subject of the reference share offer and attributable to each debenture
     will be reduced.

     X = the aggregate number of such reference shares that are surrendered and
     accepted in the reference share offer.

     N = the aggregate number of reference shares, which are the subject of the
     reference share offer, outstanding immediately prior to the closing of the
     reference share offer.

     Any portion of the average transaction consideration that does not consist
of publicly traded common equity securities will be treated as though it were
part of an extraordinary distribution by the reference company, and shall be the
object of an additional distribution by Liberty. See "-- Additional
Distributions" above.

     Any change in the reference shares attributable to a debenture that results
from a reference share offer will be deemed to have occurred immediately after
the closing of the tender or exchange offer or the effective date of the merger,
consolidation or statutory share exchange involving an election, as the case may
be.

     If following any merger, consolidation, liquidation, dissolution, exchange
offer or tender offer no reference shares were to remain outstanding, the
maturity of the debentures would not be accelerated and the debentures would
continue to remain outstanding until the stated maturity date, unless the
debentures were earlier redeemed by us. At the stated maturity or upon
redemption, holders of the debentures would only be entitled to receive the
adjusted principal amount of the debentures, plus any accrued but unpaid
interest and any final period distribution.

CALCULATIONS IN RESPECT OF THE DEBENTURES

     We will be responsible for making all calculations called for under the
debentures. These calculations include determination of:

     - the adjusted principal amount of the debentures;

     - the current market value of the reference shares;

     - the exchange market value of the reference shares;

     - any final period distribution on the debentures;

     - the cash value of any property distributed on the reference shares;

     - the average transaction consideration in a reference share offer;

     - the reference share proportionate reduction resulting from a reference
       share offer;

     - the number and composition of the reference shares attributable to a
       debenture; and

     - the amount of accrued interest payable upon redemption or at maturity of
       the debentures.

     We will make all these calculations in good faith and, absent manifest
error, our calculations will be final and binding on holders of the debentures.
We will provide a schedule of our calculations to the trustee, and the trustee
is entitled to rely upon the accuracy of our calculations without independent
verification.
                                        31
   35

FORM, DENOMINATION AND REGISTRATION

     The debentures have been issued in book-entry form only, and are
represented by global debentures registered in the name Cede & Co., as nominee
of The Depository Trust Company. The debentures are transferable on the books of
DTC in minimum denomination of $1,000 original principal amount and integral
multiples thereof.

     So long as DTC, or its nominee is the registered owner of a global
debenture, DTC or its nominee, as the case may be, will be the sole holder of
the debentures represented by the global debenture for all purposes under the
indenture. Except as otherwise provided in this section, the beneficial owners
of the global debentures representing the debentures will not be entitled to
receive physical delivery of certificated debentures and will not be considered
the holders of the debentures for any purpose under the indenture, and no global
debenture representing the book-entry debentures will be exchangeable or
transferable. Accordingly, each beneficial owner must rely on the procedures of
DTC and, if the beneficial owner is not a participant of DTC, then the
beneficial owner must rely on the procedures of the participant through which
the beneficial owner owns its interest in order to exercise any rights of a
holder under the global debentures or the indenture. The laws of some
jurisdictions may require that certain purchasers of debentures take physical
delivery of the debentures in certificated form. Such limits and laws may impair
the ability to transfer beneficial interests in a global debenture representing
the debentures.

     The global debentures representing the debentures will be exchangeable for
certificated debentures of like tenor and terms and of differing authorized
denominations aggregating a like principal amount, only if:

     - DTC notifies Liberty that it is unwilling or unable to continue as
       depositary for the global debentures;

     - DTC ceases to be a clearing agency registered under the Exchange Act;

     - Liberty in its sole discretion determines that the global debentures
       shall be exchangeable for certificated debentures; or

     - there shall have occurred and be continuing an event of default under the
       indenture with respect to the debentures; provided that interests in the
       temporary Regulation S global debentures will not be exchangeable for
       certificated debentures until expiration of the 40-day distribution
       compliance period and receipt of certification of non-U.S. beneficial
       ownership as described above.

     Upon any exchange, the certificated debentures shall be registered in the
names of the beneficial owners of the global debentures representing the
debentures, which names shall be provided by DTC's relevant participants (as
identified by DTC) to the trustee.

     Information Relating to DTC.  The following is based on information
furnished by DTC, which is the initial depositary:

     DTC will act as the depositary for the debentures. The debentures have been
issued as fully registered senior debt securities registered in the name of Cede
& Co., which is DTC's partnership nominee. Fully registered global debentures
have been issued for the debentures, in the aggregate principal amount of
$600,000,000, and have been deposited with DTC, or a custodian for its benefit.

     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds debentures that its participants deposit with it. DTC also facilitates the
settlement among participants of securities transactions, including transfers
and pledges, in deposited debentures through electronic computerized book-entry
changes to participants' accounts, thereby eliminating the need for physical
movement of senior debt securities certificates. Direct participants of DTC
include securities brokers and dealers, including the initial purchasers of the
debentures, banks, trust companies, clearing corporations and certain other
organizations. DTC is owned by a number of its direct participants, including
the initial purchaser of the debentures and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc., and the National Association of
                                        32
   36

Securities Dealers, Inc. Access to DTC's system is also available to indirect
participants, which includes securities brokers and dealers, banks and trust
companies that clear through or maintain a custodial relationship with a direct
participant, either directly or indirectly. The rules applicable to DTC and its
participants are on file with the SEC.

     Purchases of debentures under DTC's system must be made by or through
direct participants, which will receive a credit for the debentures on DTC's
record. The ownership interest of each beneficial owner, which is the actual
purchaser of each debenture, represented by global debentures, is in turn to be
recorded on the direct and indirect participants' records. Beneficial owners
will not receive written confirmation from DTC of their purchase, but beneficial
owners are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the direct
or indirect participants through which the beneficial owner entered into the
transaction. Transfers of ownership interests in the global debentures
representing the debentures are to be accomplished by entries made on the books
of participants acting on behalf of beneficial owners. Beneficial owners of the
global debentures representing the debentures will not receive certificated
debentures representing their ownership interests therein, except in the event
that use of the book-entry system for the debentures is discontinued.

     To facilitate subsequent transfers, all global debentures representing the
debentures which are deposited with, or on behalf of, DTC are registered in the
name of DTC's nominee, Cede & Co. The deposit of global debentures with, or on
behalf of, DTC and their registration in the name of Cede & Co. effect no change
in beneficial ownership. DTC has no knowledge of the actual beneficial owners of
the global debentures representing the debentures; DTC's records reflect only
the identity of the direct participants to whose accounts the debentures are
credited, which may or may not be the beneficial owners. The participants will
remain responsible for keeping account of their holdings on behalf of their
customers.

     Conveyance of notices and other communications by DTC to direct
participants, by direct participants to indirect participants, and by direct and
indirect participants to beneficial owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

     Neither DTC nor Cede & Co. will consent or vote with respect to the global
debentures representing the debentures. Under its usual procedure, DTC mails an
omnibus proxy to Liberty as soon as possible after the applicable record date.
The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those
direct participants to whose accounts the debentures are credited on the
applicable record date (identified in a listing attached to the omnibus proxy).

     Principal and/or interest payments and additional distributions on the
global debentures representing the debentures will be made to DTC. DTC's
practice is to credit direct participants' accounts on the applicable payment
date in accordance with their respective holdings shown on DTC's records unless
DTC has reason to believe that it will not receive payment on the date. Payments
by participants to beneficial owners will be governed by standing instructions
and customary practices, as is the case with debentures held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of the participant and not of DTC, the trustee or Liberty,
subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of principal and/or interest and additional distributions
to DTC is the responsibility of Liberty or the trustee, disbursement of the
payments to direct participants will be the responsibility of DTC, and
disbursement of the payments to the beneficial owners will be the responsibility
of direct and indirect participants.

     DTC may discontinue providing its services as securities depositary with
respect to the debentures at any time by giving reasonable notice to Liberty or
the trustee. Under such circumstances, in the event that a successor securities
depositary is not obtained, certificated debentures are required to be printed
and delivered.

     Liberty may decide to discontinue use of the system of book-entry transfers
through DTC or a successor securities depositary. In that event, certificated
debentures will be printed and delivered.

     Although DTC has agreed to the procedures described above in order to
facilitate transfers of interests in the global debentures among participants of
DTC, it is under no obligation to perform or continue to perform
                                        33
   37

these procedures, and these procedures may be discontinued at any time. Neither
the trustee nor Liberty will have any responsibility for the performance by DTC
or its respective participants or indirect participants of its obligations under
the rules and procedures governing its operations.

     The information in this subsection concerning DTC and its respective
book-entry system has been obtained from sources that Liberty believes to be
reliable, but Liberty takes no responsibility for its accuracy.

CERTAIN COVENANTS

     The covenants set forth below are contained in the indenture and are
applicable to Liberty and its Subsidiaries.

     Limitation on Liens.  Liberty will not, and will not permit any Restricted
Subsidiary to, create, incur or assume any Lien, except for Permitted Liens, on
any Principal Property to secure the payment of Funded Indebtedness of Liberty
or any Restricted Subsidiary if, immediately after the creation, incurrence or
assumption of such Lien, the sum of (A) the aggregate outstanding principal
amount of all Funded Indebtedness of Liberty and the Restricted Subsidiaries
that is secured by Liens (other than Permitted Liens) on any Principal Property
and (B) the Attributable Debt relating to any Sale and Leaseback Transaction
which would otherwise be subject to the provisions of clause 2(A)(i) of the
"Limitation on Sale and Leaseback" covenant would exceed 15% of the Consolidated
Asset Value, unless effective provision is made whereby the debentures (together
with, if Liberty shall so determine, any other Funded Indebtedness ranking

     such merger, consolidation or acquisition;

          (3) Liens existing on the date of original issuance of the debentures;

     Liens referred to in clauses (2), (3), (4), (5), (6) and (7) above,
     provided that the principal of the Funded Indebtedness secured thereby does

        created) are secured equally and ratably with (or prior to) the
        obligations of Liberty or the Restricted Subsidiary under the lease of
        the Principal Property that is the subject of the Sale and Leaseback
        Transaction, or

             (B) within 180 days, Liberty or the Restricted Subsidiary either
        (i) applies an amount equal to the fair market value of the Principal

the end of such fiscal year), which Officers' Certificate shall state the
effective date of such designation; Liberty has made the initial designation of

Officers' Certificate with respect thereto to the trustee, on or prior to the
date of initial issuance of the debentures.

     than by the declaration of acceleration and interest on the senior debt
     securities; and

in aggregate principal amount of the outstanding senior debt securities of any
series may, on behalf of the holders of all senior debt securities of the
series, waive any past default and its consequences under the indenture with
respect to the senior debt securities of the series, except a default

     - in the payment of principal (or premium, if any), or any interest or
       distributions on, or any additional amounts with respect to, senior debt
       securities of the series, or

     - in respect of a covenant or provision of the indenture that cannot be

           SUMMARY OF REGISTRATION RIGHTS OF SELLING SECURITY HOLDERS

     We entered into a registration rights agreement with the initial purchaser
of the debentures, pursuant to which we filed with the SEC and caused to become
effective a shelf registration statement of which this prospectus is a part.
Pursuant to the registration rights agreement, we are required to:

     - use our reasonable best efforts to keep effective the shelf registration
       statement until two years after the issue date or until all of the
       debentures covered by the shelf registration statement have been sold,
       exchanged or redeemed or otherwise cease to be outstanding; and

     - use our reasonable best efforts to ensure that:

      - the shelf registration statement and any amendment thereto and any
        prospectus included therein comply in all material respects with the
        Securities Act; and

      - the shelf registration statement and any amendment thereto and any
        prospectus included therein do not, when the shelf registration
        statement or any amendment becomes effective, contain an untrue
        statement of a material fact.

     If the shelf registration statement is unusable by the holders for any
reason for more than 30 days in the aggregate in any consecutive 12-month
period, then the interest rate borne by the debentures will be increased by
0.25% per annum of the principal amount of the debentures for the first 90-day
period (or portion thereof) beginning on the 31st day that the shelf
registration statement ceased to be usable. This interest rate will be increased
by an additional 0.25% per annum of the principal amount of the debentures at
the beginning of each subsequent 90-day period, provided that the maximum
aggregate increase in the interest rate will in no event exceed one percent (1%)
per annum. Upon the shelf registration statement once again becoming usable, the
interest rate borne by the debentures will be reduced to the original interest
rate. Additional interest shall be computed based on the actual number of days
elapsed in each 90-day period in which the shelf registration statement is
unusable.

     Liberty shall notify the trustee within three business days of an event
date, which is each and every date on which an event occurs in respect of which
additional interest is required to be paid. Additional interest shall be paid by
depositing with the trustee, in trust, for the benefit of the holders of the
debentures, on or before the applicable semiannual interest payment date,
immediately available funds in sums sufficient to pay the additional interest
then due. The additional interest due shall be payable on each interest payment
date to the record holder of debentures entitled to receive the interest payment
to be paid on such date as set forth in the indenture. Each obligation to pay
additional interest shall be deemed to accrue from and including the date
following the applicable event date.

     The registration rights agreement has been filed as an exhibit to the
registration statement of which this prospectus forms a part, and we refer you
to the registration rights agreement for a complete description of its terms.
See "Where to Find More Information." The registration rights agreement requires
us to pay substantially all of the expenses incident to the registration,
offering, and sale of the debentures to the public, other than commissions,
concessions and discounts of underwriters, dealers or agents, but including the
fees and disbursements of one counsel for the selling security holders. We have
agreed to indemnify the selling security holders and any underwriters they may
use against certain civil liabilities, including liabilities under the
Securities Act.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the material United States federal income tax
consequences of the acquisition, ownership and disposition of the debentures and
of the Motorola stock for which the debentures may be exchanged. This summary is
based upon the United States Internal Revenue Code of 1986, as amended (which we
refer to as the "Code"), administrative pronouncements, judicial decisions, and
existing and proposed Treasury Regulations, changes to any of which subsequent
to the date of this prospectus may affect the tax consequences described in this
prospectus, possibly with retroactive effect. This summary deals only with
holders that will hold the debentures and Motorola stock for which the
debentures may be exchanged as "capital assets" within the meaning of Section
1221 of the Code, and does not address tax considerations applicable to holders
that may be subject to special tax rules, such as dealers or traders in
securities, financial institutions, tax-exempt entities, holders that hold the
debentures as a part of a hedging, straddle, conversion or other integrated
transaction, or U.S. Holders (as defined below) whose functional currency is not
the United States dollar. The following summary assumes that the reference
shares received upon maturity, exchange or redemption of the debentures will
consist of Motorola stock.

     THE DISCUSSION SET OUT BELOW IS INTENDED ONLY AS A SUMMARY OF CERTAIN
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN THE
DEBENTURES. PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO
THE TAX CONSEQUENCES OF AN INVESTMENT IN THE DEBENTURES, INCLUDING THE
APPLICATION TO THEIR PARTICULAR SITUATIONS OF THE TAX CONSIDERATIONS DISCUSSED
BELOW, AS WELL AS THE APPLICATION OF STATE, LOCAL OR FOREIGN TAX LAWS.

     "U.S. Holder" means a beneficial owner of the debentures or Motorola stock,
as the case may be, that is, for United States federal income tax purposes, (i)
an individual citizen or resident of the United States, (ii) a corporation,
partnership, or other entity created or organized in or under the laws of the
United States or any political subdivision thereof, (iii) an estate the income
of which is subject to United States federal income taxation regardless of its
source or (iv) in general, a trust which is subject to the primary supervision
of a United States court and the control of one or more United States
fiduciaries. "Non-U.S. Holder" means any holder of the debentures or Motorola
stock, as the case may be, that is not a U.S. Holder.

TAX CONSEQUENCES TO U.S. HOLDERS

     Interest Accrual on the Debentures.  For United States federal income tax
purposes, the debentures will be subject to Treasury Regulations relating to
contingent payment debt instruments (which we refer to as the contingent payment
debt regulations). Under the contingent payment debt regulations, a U.S. Holder
will be required to accrue interest income on the debentures (in amounts
described in the next paragraph) regardless of whether such U.S. Holder uses the
cash or accrual method of tax accounting. As a result, a U.S. Holder will be
required to include interest in taxable income each year in excess of the
semi-annual interest payments received in that year.

     Under the contingent payment debt regulations, for each accrual period
prior to and including the maturity date of the debentures, the amount of
interest that accrues, as original issue discount, on a debenture equals the
product of (a) the adjusted issue price (as defined below) as of the beginning
of the accrual period and (b) the comparable yield (as defined below) (adjusted
for the length of the accrual period). This amount is ratably allocated to each
day in the accrual period and is includable as ordinary interest income by a
U.S. Holder for each day in the accrual period on which the U.S. Holder holds
the debentures.

     The "adjusted issue price" means the issue price of the debenture, which is
$1,000, increased by any interest previously accrued (determined without regard
to any adjustments to interest accruals described below) and decreased by the
amount of any projected payments (as defined below) with respect to the
debenture.

     The "comparable yield" means the annual yield we would pay, as of the issue
date, on a fixed-rate debt security with no exchange right or other contingent
payments but with terms and conditions otherwise comparable to those of the
debentures. Amounts treated as interest under the contingent payment debt
regulations are treated as original issue discount for all purposes of the Code.

                                        44
   48

     We have determined that the comparable yield is 9.5%, compounded
semi-annually. Under the contingent payment debt regulations, we are required,
solely for United States federal income tax purposes, to provide a schedule of
the projected amounts of payments (which we refer to as projected payments) on
the debentures. This schedule must produce the comparable yield. Based on our
determination of the comparable yield, the schedule of projected payments
(assuming a principal amount of $1,000 and an issue price of $1,000, and with
respect to each integral multiple thereof) consists of (a) a payment of stated
interest equal to $17.89 on July 15, 2001, (b) payments of stated interest equal
to $17.50 on all subsequent semi-annual interest payment dates (including the
maturity date) and (c) a payment of a projected amount at the maturity date of
the debentures (excluding the stated semi-annual interest on the debentures
payable on such date) equal to $10,603.87. For United States federal income tax
purposes, a U.S. Holder is required to use the comparable yield and the schedule
of projected payments in determining its interest accruals and adjustments
thereof in respect of the debentures, unless such U.S. Holder timely discloses
and justifies the use of other estimates to the IRS.

     THE COMPARABLE YIELD AND THE SCHEDULE OF PROJECTED PAYMENTS ARE NOT
PROVIDED FOR ANY PURPOSE OTHER THAN THE DETERMINATION OF HOLDERS' INTEREST
ACCRUALS AND ADJUSTMENTS THEREOF IN RESPECT OF THE DEBENTURES FOR UNITED STATES
FEDERAL INCOME TAX PURPOSES AND DO NOT CONSTITUTE A PROJECTION OR REPRESENTATION
REGARDING THE ACTUAL AMOUNTS PAYABLE ON THE DEBENTURES.

     Adjustments to Interest Accruals.  If, during any taxable year, the sum of
any actual payments with respect to the debentures for that taxable year
(including excess regular cash dividend amounts, extraordinary distributions
and, in the case of the taxable year which includes the maturity date of the
debentures, the fair market value of any Motorola stock received by such holder,
plus the fair market value of any other property received, plus the amount of
cash received) exceeds the total amount of projected payments for that taxable
year, the difference will produce a "net positive adjustment" under the
contingent payment debt regulations, which will be treated as additional
interest for the taxable year. For this purpose, the payments in a taxable year
include the fair market value of property received in that year. If the actual
amount received in a taxable year is less than the amount of projected payments
for that taxable year, the difference will produce a "net negative adjustment"
under the contingent payment debt regulations, which will (a) reduce the U.S.
Holder's interest income on the debentures for that taxable year and (b) to the
extent of any excess after the application of (a), give rise to an ordinary loss
to the extent of the U.S. Holder's interest income on the debentures during
prior taxable years (reduced to the extent such interest was offset by prior net
negative adjustments).

     Sale or Exchange of the Debentures.  Upon the sale, exchange or retirement
of the debentures (including, for instance, an exchange at the U.S. Holder's
option for Motorola stock or the redemption of the debentures by us) prior to
the maturity date, the U.S. Holder will recognize gain or loss equal to the
difference between the amount realized and the U.S. Holder's adjusted basis. A
U.S. holder will be treated as receiving an amount equal to the fair market
value of any Motorola stock received, plus the fair market value of any other
property received, plus the amount of any cash received. The adjusted basis will
be the U.S. Holder's original basis in the debentures, increased by the interest
income previously included by the U.S. Holder with respect to the debentures
(determined without regard to any adjustments to interest accruals described in
the preceding paragraph) and decreased by the projected amount of all prior
payments with respect to the debentures. (See below under Purchase for Premium
or Discount for additional adjustments made with respect to U.S. Holders who did
not purchase debentures in the initial offering.) Any gain upon sale or exchange
of the debentures will be ordinary interest income; any loss will be ordinary
loss to the extent of the interest previously included in income by the U.S.
Holder with respect to the debentures, and thereafter, capital loss. The
distinction between capital loss and ordinary loss is potentially significant in
several respects. For example, limitations apply to a U.S. Holder's ability to
offset capital losses against ordinary income.

     Purchase for Premium or Discount.  A purchase of a debenture by a U.S.
Holder will cause the new U.S. Holder to have a basis in the debenture equal to
the amount paid for the debenture. A U.S. Holder is required to reasonably
allocate any difference between the adjusted issue price of the debenture and
such U.S. Holder's basis in the debenture to daily portions of interest or
projected payments over the remaining
                                        45
   49

term of debenture. If such basis in the debenture exceeds the debenture's
adjusted issue price, the amount of the difference allocated to a daily portion
of interest or to a projected payment is treated as a negative adjustment on the
date the daily portion accrues or the payment is made. On the date of the
adjustment, the U.S. Holder's adjusted basis in the debenture is reduced by the
amount the U.S. Holder so treats as a negative adjustment. If the new U.S.
Holder's basis in the debenture is less than the debenture's adjusted issue
price, the amount of the difference allocated to a daily portion of interest or
to a projected payment is treated as a positive adjustment on the date the daily
portion accrues or the payment is made. On the date of the adjustment, the U.S.
Holder's adjusted basis in the debenture is increased by the amount the U.S.
Holder so treats as a positive adjustment.

     Distributions on Motorola Stock.  The gross amount of any distribution made
by Motorola to a U.S. Holder with respect to the Motorola stock generally will
be includable in the income of a U.S. Holder as dividend income to the extent
that such distribution is paid out of Motorola's current or accumulated earnings
and profits as determined under U.S. federal income tax principles. Subject to
certain limitations, United States corporations holding Motorola stock that
receive dividends thereon generally will be eligible for a dividends-received
deduction equal to 70% of the dividends received. If the amount of any
distribution exceeds Motorola's current and accumulated earnings and profits as
so computed, such excess first will be treated as a tax-free return of capital
to the extent of the U.S. Holder's tax basis in its Motorola stock, and
thereafter as gain from the sale or exchange of property.

     Dispositions of Motorola Stock.  A U.S. Holder generally will recognize
capital gain or loss for U.S. federal income tax purposes on the sale or
disposition of Motorola stock in an amount equal to the difference between the
amount realized on the sale or other disposition and the U.S. Holder's tax basis
in the Motorola stock. Any such gain or loss will be long-term gain or loss if
the U.S. Holder held the Motorola stock for more than one year. A U.S. Holder
that received Motorola stock from Liberty in a disposition of a debenture either
on or before the maturity date will have a basis in that Motorola stock equal to
that stock's fair market value on the date of such disposition of the debenture.
Additionally, the U.S. Holder's holding period in the Motorola stock will begin
the day after such disposition of the debenture.

     Backup Withholding.  Certain noncorporate U.S. Holders may be subject to
backup withholding at a rate of 31% on payments of principal and interest
(including original issue discount) on, or the proceeds of disposition of, the
debentures and dividends on the Motorola stock. Backup withholding will apply
only if the U.S. Holder (a) fails to furnish its Taxpayer Identification Number
(which we refer to as TIN) which, for an individual, is his or her Social
Security number, (b) furnishes an incorrect TIN, (c) is notified by the IRS that
it has failed to properly report payments of interest and dividends or (d) under
certain circumstances, fails to certify, under penalties of perjury, that it has
furnished a correct TIN and has not been notified by the IRS that it is subject
to backup withholding for failure to report interest and dividend payments. U.S.
Holders should consult their tax advisors regarding their qualification for
exemption from backup withholding and the procedure for obtaining such an
exemption if applicable.

     The amount of any backup withholding from a payment to a U.S. Holder will
be allowed as a credit against such U.S. Holder's United States federal income
tax liability and may entitle such U.S. Holder to a refund, provided that the
required information is furnished to the IRS.

TAX CONSEQUENCES TO NON-U.S. HOLDERS

     Withholding.  Under present United States federal income tax law, and
subject to the discussion below concerning backup withholding, payments of
principal and interest (including original issue discount) on the debentures by
us or any paying agent to any Non-U.S. Holder, and gain realized on the sale or
exchange of the debentures or Motorola stock by a Non-U.S. Holder, will be
exempt from United States federal income or withholding tax, provided that:

     - such Non-U.S. Holder does not own, actually or constructively, 10 percent
       or more of the total combined voting power of all classes of our stock
       entitled to vote, is not a controlled foreign corporation related,
       directly or indirectly, to us through stock ownership, and is not a bank
       receiving interest described in Section 881(c)(3)(A) of the Code;
                                        46
   50

     - the statement requirement set forth in Section 871(h) or Section 881(c)
       of the Code has been fulfilled with respect to the beneficial owner, as
       discussed below;

     - such Non-U.S. Holder is not an individual who is present in the United
       States for 183 days or more in the taxable year of disposition or who is
       subject to special rules applicable to former citizens and residents of
       the United States;

     - such payments and gain are not effectively connected with the conduct by
       such Non-U.S. Holder of a trade or business in the United States; and

     - the Motorola stock continues to be actively traded within the meaning of
       Section 871(h)(4)(C)(v)(I) of the Code (which, for these purposes and
       subject to certain exceptions, includes trading on the NYSE).

     The statement requirement referred to in the preceding paragraph will be
fulfilled if the beneficial owner of a debenture certifies on an appropriate
form (generally IRS Form W-8BEN), under penalties of perjury, that it is not a
United States person and provides its name and address, and (a) the beneficial
owner files that form with the withholding agent or (b) a securities clearing
organization, bank or other financial institution holding customers' securities
in the ordinary course of its trade or business holds the debentures on behalf
of the beneficial owner, files with the withholding agent a statement that it
has received the Form W-8BEN from the beneficial owner and furnishes the
withholding agent with a copy thereof. With respect to any debentures held by a
foreign partnership, unless the foreign partnership has entered into a
withholding agreement with the IRS, each partner that is a Non-U.S. Holder will
be required to supply this certification in order to avoid withholding with
respect to such partner's share of interest (including original issue discount)
and disposition proceeds paid with respect to the debentures to the foreign
partnership.

     Distributions by Motorola with respect to Motorola stock that are treated
as dividends paid, as described above under "-- Tax Consequences to U.S.
Holders -- Distributions on Motorola Stock," to a Non-U.S. Holder (excluding
dividends that are effectively connected with the conduct of a trade or business
in the United States by such Holder and are taxable as described below) will be
subject to United States federal withholding tax at a 30% rate (or lower rate
provided under any applicable income tax treaty).

     If a Non-U.S. Holder of the debentures or Motorola stock is engaged in a
trade or business in the United States, and if interest on the debentures,
dividends on the Motorola stock, or gain from the sale or exchange of the
debentures or Motorola stock are effectively connected with the conduct of such
trade or business, the Non-U.S. Holder, although exempt from the withholding tax
discussed in the preceding paragraphs, will generally be subject to regular
United States federal income tax on such interest, dividends, or gain realized
on the sale or exchange of the debentures or Motorola stock in the same manner
as if it were a U.S. Holder. In lieu of the certificate described in the
preceding paragraph, such a Non-U.S. Holder will be required to provide to the
withholding agent a properly executed IRS Form W-8ECI (or successor form) in
order to claim an exemption from withholding tax. In addition, if such a
Non-U.S. Holder is a foreign corporation, it may be subject to a branch profits
tax equal to 30% (or such lower rate provided by an applicable treaty) of its
effectively connected earnings and profits for the taxable year, subject to
certain adjustments.

     Backup Withholding and Information Reporting.  Backup withholding (at the
rate of 31%) will not apply to payments made by us or a paying agent on the
debentures or Motorola stock if the certifications required by Sections 871(h)
or 881(c) are received, provided in each case that we or such paying agent, as
the case may be, do not have actual knowledge and do not have reason to know
that the payee is a United States person.

     Non-U.S. Holders of the debentures and Motorola stock should consult their
tax advisors regarding the application of information reporting and backup
withholding in their particular situations, the availability of an exemption
therefrom, and the procedure for obtaining such an exemption, if available. Any
amounts withheld from a payment to a Non-U.S. Holder under the backup
withholding rules will be allowed as a credit against such Non-U.S. Holder's
United States federal income tax liability and may entitle such Non-U.S. Holder
to a refund, provided that the required information is furnished to the IRS.

                              PLAN OF DISTRIBUTION

     We will not receive any of the proceeds from sales of debentures by selling
security holders. The debentures may be sold from time to time:

     - directly by any selling holder to one or more purchasers;

     - to or through underwriters, brokers or dealers;

     - through agents on a best-efforts basis or otherwise; or

     - through a combination of such methods of sale.

     If debentures are sold through underwriters, brokers and dealers, the
selling security holder will be responsible for underwriting discounts or
agent's commissions.

     The debentures may be sold:

     - in one or more transactions at a fixed price or prices, which may be
       changed;

     - at prevailing market prices at the time of sale or at prices related to
       such prevailing prices;

     - at varying prices determined at the time of sale; or

     - at negotiated prices.

     Such sales may be effected in transactions (which may involve crosses or
block transactions):

     - on any national securities exchange or quotation service on which the
       debentures may be listed or quoted at the time of sale;

     - in the over-the-counter market;

     - in transactions otherwise than on such exchanges or services or in the
       over-the-counter market; or

     - through the writing of options.

     In connection with the sale of the debentures, any selling security holder
may:

     - enter into hedging transactions with brokers, dealers or others, which
       may in turn engage in short sales of the debentures in the course of
       hedging the positions they assume;

     - sell short or deliver debentures to close out such short positions; or

     - loan or pledge debentures to brokers, dealers or others that may in turn
       sell such securities.

     Any selling security holder may pledge or grant a security interest in some
or all of the debentures owned by it, and if it defaults in the performance of
its secured obligations, the pledgees or secured party may sell from time to
time the pledged debentures pursuant to the registration statement of which this
prospectus is a part. The selling security holders may also transfer and donate
debentures in other circumstances in which case the transferees, donees,
pledgees or other successors in interest will be the selling security holders
for purposes of this prospectus.

     Underwriters, brokers, dealers and agents may receive compensation in the
form of underwriting discounts, concessions or commissions from the selling
security holders or the purchaser of debentures for whom they may act as agent.
The selling security holders and any underwriters, dealers or agents that
participate in the distribution of debentures may be deemed to be "underwriters"
within the meaning of the Securities Act, and any profit on the sale of
debentures by them and any discounts, commissions or concessions received by
them might be deemed to be underwriting discounts and commissions under the
Securities Act.

                                        48
   52

     There is currently no active trading market for the debentures. We do not
presently intend to list the debentures on any stock exchange. Therefore, any
trading with respect to the debentures is expected to occur in over-the-counter
markets.

     At the time a particular offering or sale of debentures is made, a
prospectus supplement, if required, will be distributed which will set forth the
aggregate amount of debentures offered or sold and the terms of the offering or
sale, including the name or names of any underwriters, dealers or agents, any
discounts, commissions and other terms constituting compensation from the
selling security holders and any discounts, commissions or concessions allowed
or reallowed or paid to dealers.

     To comply with the securities laws of certain jurisdictions, if applicable,
the debentures can be offered or sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain jurisdictions
the debentures may not be offered or sold unless they have been registered or
qualified for sale in such jurisdictions or an exemption from registration or
qualification is available and is complied with.

     There is no assurance that the selling security holders will sell any of
the debentures. In addition, any debentures covered by this prospectus which
qualify for sale pursuant to Rule 144 or Rule 144A under the Securities Act may
be sold pursuant to Rule 144 or Rule 144A rather than pursuant to this
prospectus.

                                 LEGAL MATTERS

     The validity of the debentures will be passed upon for us by Baker Botts

     The consolidated balance sheets of Liberty Media Corporation and
subsidiaries ("New Liberty or Successor") as of December 31, 2000 and 1999, and
the related consolidated statements of operations and comprehensive earnings,
stockholder's equity, and cash flows for the year ended December 31, 2000 and
for the period from March 1, 1999 to December 31, 1999 (Successor periods) and
from January 1, 1999 to February 28, 1999 and for the year ended December 31,
1998 (Predecessor periods) have been incorporated by reference herein in
reliance upon the report, dated February 26, 2001, except as to notes 1 and 2,
which are as of May 7, 2001, of KPMG LLP, independent certified public
accountants, incorporated by reference herein, and upon the authority of said
firm as experts in accounting and auditing.

     In addition the KPMG LLP report contains an explanatory paragraph and
states that effective March 9, 1999, AT&T Corp., the former parent company of
New Liberty, acquired Tele-Communications, Inc., the former parent company of
Old Liberty, in a business combination accounted for as a purchase. As a result
of the acquisition, the consolidated financial information for the periods after
the acquisition is presented on a different cost basis than that for the periods
before the acquisition and, therefore, is not comparable.

     The consolidated financial statements of Teligent, Inc. as of December 31,
2000 and 1999 and for each of the three years in the period ended December 31,
2000 and the related financial statement schedule included in Teligent Inc.'s
Annual Report (Form 10-K/A) for the year ended December 31, 2000 and
incorporated by reference in this prospectus and registration statement, have
been audited by Ernst & Young LLP, independent auditors, as set forth in their
report thereon included therein and incorporated herein by reference (which
report contains explanatory paragraphs describing conditions that raise
substantial doubt about Teligent, Inc.'s ability to continue as a going concern
as more fully described in Note 1 to the consolidated financial statements, and
the restatement of the December 31, 2000 consolidated balance sheet to reflect
the classification of Teligent, Inc.'s outstanding debt from a long-term
liability to a current liability). Such consolidated financial statements are
incorporated herein by reference in reliance upon such report given upon the
authority of such firm as experts in accounting and auditing.

                         WHERE TO FIND MORE INFORMATION

     We have filed with the SEC a registration statement on Form S-3 under the
Securities Act with respect to the debentures that may be sold by this
prospectus. This prospectus, which forms a part of the registration statement,
does not contain all the information included in the registration statement. You
should refer to the registration statement, including its exhibits and
schedules, for further information about us or the debentures that may be sold
by this prospectus. Statements contained in this prospectus as to the contents
of any contract or other document are not necessarily complete, and, where any
contract or other document is an exhibit to the registration statement, we refer
you to that exhibit for a more complete description of the matter involved.

     The SEC allows us to "incorporate by reference" information into this
document, which means that we can disclose important information to you by
referring you to other documents. The information incorporated by reference is
an important part of this prospectus, and is deemed to be part of this document
except for any information superceded by this document or any other document
incorporated by reference in this document. We incorporate by reference the
documents listed below and any future filings made by us with the SEC under
Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934:

     - Annual Report on Form 10-K for the year ended December 31, 2000, filed on
       March 28. 2001, as amended by the Annual Report on Form 10-K/A for the
       year ended December 31, 2000, filed on June 12, 2001.

     - Quarterly Report on Form 10-Q for the three-month period ending March 31,
       2001, filed on May 14, 2001, as amended by the Quarterly Report on Form
       10-Q/A for the three month period ending March 31, 2001, filed on June
       20, 2001.

     - Current Report on Form 8-K, filed on March 7, 2001.

     - Current Report on Form 8-K, filed on June 26, 2001.

     - The consolidated financial statements of Teligent, Inc., as of December
       31, 2000 and 1999 and for each of the years in the three year period
       ended December 31, 2000, which appear in the Annual Report on Form 10-K/A
       for the year ended December 31, 2000 of Teligent, Inc., filed on July 5,
       2001. On May 21, 2001, Teligent, Inc. and all of its direct and indirect
       domestic subsidiaries filed voluntary petitions for relief under Chapter
       11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for
       the Southern District of New York.

     On May 17, 2001, certain subsidiaries and assets of AT&T Corp. which had
previously been attributed to AT&T's Liberty Media Group but which had not been
previously held by Liberty Media Corporation were contributed to Liberty Media
Corporation in anticipation of its split off from AT&T. Those subsidiaries and
assets, which constitute only a portion of our overall assets, are being
accounted for in a manner similar to a pooling of interests and, therefore, the
financial statements of Liberty Media Corporation for periods prior to the
contributions have been restated to include the financial position and results
of operations of the contributed assets from the dates of their acquisition by
AT&T. Accordingly, the following information is incorporated by reference from
the Registration Statement on Form S-1 of Liberty Media Corporation,
Registration No. 333-55998, declared effective on June 14, 2001, with respect to
the split off: (1) the information under the captions titled "Capitalization,"
"Selected Financial Information" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and (2) the following financial
statements and notes thereto of Liberty Media Corporation and subsidiaries,
which have been restated to give effect to the aforementioned contribution: (x)
the balance sheets of Liberty Media Corporation as of March 31, 2001 and
December 31, 2000, and the related consolidated statements of operations and
comprehensive earnings, stockholder's equity, and cash flows for the three
months ended March 31, 2001 and 2000; and (y) the balance sheets of Liberty
Media Corporation as of December 31, 2000 and 1999 and the related consolidated
statements of operations and comprehensive earnings, stockholder's equity, and
cash flows for the year ended December 31, 2000, and the period from March 1,
1999 to December 31, 1999 (Successor periods) and from January 1, 1999 to
February 28, 1999 and for the year ended December 31, 1998 (Predecessor
periods).

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law ("DGCL") provides,
generally, that a corporation shall have the power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (except actions by or in the right of
the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation against all expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. A corporation may similarly indemnify such person for
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of any action or suit by or in the right of the
corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of claims, issues and matters as to which such
person shall have been adjudged liable to the corporation, provided that a court
shall have determined, upon application, that, despite the adjudication of
liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

     Section 102(b)(7) of the DGCL provides, generally, that the certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
may not eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under section 174 of Title 8 of the Delaware
General Corporation Law, or (iv) for any transaction from which the director
derived an improper personal benefit. No such provision may eliminate or limit
the liability of a director for any act or omission occurring prior to the date
when such provision became effective.

     Article V, Section E of the Restated Certificate of Incorporation, as
amended ("Liberty charter"), of Liberty Media Corporation, a Delaware
corporation ("Liberty"), provides as follows:

          1. Limitation On Liability.  To the fullest extent permitted by the
     DGCL as the same exists or may hereafter be amended, a director of Liberty
     shall not be liable to Liberty or any of its stockholders for monetary
     damages for breach of fiduciary duty as a director. Any repeal or
     modification of this paragraph 1 shall be prospective only and shall not
     adversely affect any limitation, right or protection of a director of
     Liberty existing at the time of such repeal or modification.

                                       II-1
   57

          2. Indemnification.

             (a) Right to Indemnification.  Liberty shall indemnify and hold
        harmless, to the fullest extent permitted by applicable law as it
        presently exists or may hereafter be amended, any person who was or is
        made or is threatened to be made a party or is otherwise involved in any
        action, suit or proceeding, whether civil, criminal, administrative or
        investigative (a "proceeding") by reason of the fact that he, or a
        person for whom he is the legal representative, is or was a director or
        officer of Liberty or is or was serving at the request of Liberty as a
        director, officer, employee or agent of another corporation or of a
        partnership, joint venture, trust, enterprise or nonprofit entity,
        including service with respect to employee benefit plans, against all
        liability and loss suffered and expenses (including attorneys' fees)
        reasonably incurred by such person. Such right of indemnification shall
        inure whether or not the claim asserted is based upon matters which
        antedate the adoption of this Section E. Liberty shall be required to
        indemnify or make advances to a person in connection with a proceeding
        (or part thereof) initiated by such person only if the proceeding (or
        part thereof) was authorized by the board of directors of Liberty.

             (b) Prepayment of Expenses.  Liberty shall pay the expenses
        (including attorneys' fees) incurred by a director or officer in
        defending any proceeding in advance of its final disposition, provided,
        however, that the payment of expenses incurred by a director or officer
        in advance of the final disposition of the proceeding shall be made only
        upon receipt of an undertaking by the director or officer to repay all
        amounts advanced if it should be ultimately determined that the director
        or officer is not entitled to be indemnified under this paragraph or
        otherwise.

             (c) Claims.  If a claim for indemnification or payment of expenses
        under this paragraph is not paid in full within 60 days after a written
        claim therefor has been received by Liberty, the claimant may file suit
        to recover the unpaid amount of such claim and, if successful in whole
        or in part, shall be entitled to be paid the expense of prosecuting such
        claim. In any such action, Liberty shall have the burden of proving that
        the claimant was not entitled to the requested indemnification or
        payment of expenses under applicable law.

             (d) Non-Exclusivity of Rights.  The rights conferred on any person
        by this paragraph shall not be exclusive of any other rights which such
        person may have or hereafter acquire under any statute, provision of the
        Liberty Charter, Liberty's Bylaws, agreement, vote of stockholders or
        resolution of disinterested directors or otherwise.

             (e) Other Indemnification.  Liberty's obligation, if any, to
        indemnify any person who was or is serving at its request as a director,
        officer, employee or agent of another corporation, partnership, joint
        venture, trust, enterprise or nonprofit entity shall be reduced by any
        amount such person may collect as indemnification from such other
        corporation, partnership, joint venture, trust, enterprise or nonprofit
        entity.

          3. Amendment or Repeal.  Any amendment, modification or repeal of the
     foregoing provisions of this Section E shall not adversely affect any right
     or protection hereunder of any person in respect of any act or omission
     occurring prior to the time of such amendment, modification or repeal.

ITEM 17. UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
Liberty pursuant to the foregoing provisions, or otherwise, Liberty has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by Liberty of
expenses incurred or paid by a director, officer or controlling person of
Liberty in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities being registered, Liberty will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.
