ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

BENNETT EMPLOYMENT AGREEMENT

         As previously announced, Mr. Bennett resigned as Chief Executive
Officer of Liberty Media Corporation (the Company) on August 2, 2005, but
continued as the President and a director of the Company. On November 8, 2005,
the Board of Directors of the Company, in recognition of Mr. Bennett's many
years of service and his contributions to the Company, approved compensation and
other arrangements for Mr. Bennett, as described in the Company's Current Report
on Form 8-K, dated November 8, 2005 (File No. 001-16615). These arrangements
have now been memorialized in an Employment Agreement entered into between the
Company and Mr. Bennett, as of December 28, 2005. The Employment Agreement
provides as follows:

         Through March 31, 2006, Mr. Bennett is entitled to continue receiving
his base salary of $1,000,000 per annum. He is also entitled to receive a
performance bonus in the amount of $750,000. Mr. Bennett will cease to be
President of the Company no later than March 31, 2006. From April 1, 2006
through March 31, 2008, Mr. Bennett will remain employed by the Company and will
be entitled to receive a base salary at the rate of $500,000 per annum. Also
through March 31, 2008, he will be entitled to office support services and to
use of the Company's New York City apartment. From April 1, 2008 through August
31, 2014, Mr. Bennett will continue to be employed by the Company and will be
entitled to receive a base salary at the rate of $3,000 per annum and an
additional amount of cash compensation based on the hours of service he provides
to the Company at an hourly rate to be agreed by the Company and Mr. Bennett.
Mr. Bennett is also entitled to continue his participation in the Company's
savings and welfare benefit plans and programs through August 31, 2014, subject
to the terms and conditions of those plans.

         The foregoing compensation and benefit arrangements are subject to the
earlier termination of Mr. Bennett's employment (i) upon his death, (ii) by the
Company in connection with his disability, (iii) by the Company for cause or
(iv) by Mr. Bennett for any reason. If his employment terminates by reason of
his death or disability (A) prior to April 1, 2008, Mr. Bennett (or his estate)
will be entitled to receive his base salary through March 31, 2008, or (B) on or
after April 1, 2008 but prior to August 31, 2014, Mr. Bennett (or his estate)
will be entitled to receive his base salary through August 31, 2014. If Mr.
Bennett's employment is terminated (x) by the Company for cause or (y) by Mr.
Bennett, he will be entitled to receive his base salary through the date of
termination.

         All of Mr. Bennett's existing stock incentive awards with respect to
Company common stock are currently exercisable, and Mr. Bennett will continue to
be treated as employed by the Company for all purposes under such awards during
the term of his employment under the Employment Agreement.

         For the period August 2, 2005 through April 30, 2006, Mr. Bennett is
entitled to an aggregate of 60 hours of personal use of the Company's aircraft,
to be valued for compensation purposes in accordance with applicable tax
regulations. This arrangement supersedes any prior agreement between Mr. Bennett
and the Company regarding Mr. Bennett's personal use of the Company's aircraft.

         Mr. Bennett's deferred compensation arrangements are governed by
separate agreements which are described below.

         The foregoing description of the Employment Agreement is not complete
and is qualified in its entirety by reference to the full text of the Employment
Agreement, which is filed as Exhibit 99.1 hereto.

BENNETT DEFERRED COMPENSATION AGREEMENTS

         The American Jobs Creation Act of 2004 and related regulations and
pronouncements made by the Internal Revenue Service (collectively, the AJCA)
impose significant restrictions on deferred compensation arrangements for U.S.
taxpayers. Any U.S. taxpaying employees with a deferred compensation arrangement

                                       1


that does not comply with the AJCA will be subject to an additional 20% tax
above income tax rates, together with acceleration of income and other possible
penalties. As a protective measure, in order to avoid the potential application
of additional taxes under the AJCA, the Company and Mr. Bennett have amended and
restated two of Mr. Bennett's deferred compensation agreements. The Company and
Mr. Bennett are also party to a third deferred compensation agreement, which is
also described below.

         On December 28, 2005, the Company and Mr. Bennett amended and restated
Mr. Bennett's Deferred Compensation Agreement, originally dated January 1, 2004
(as so amended and restated, the January 2004 Agreement). The original agreement
provided for the Company to credit $12,500 to an account in the name of Mr.
Bennett at the end of each calendar quarter beginning with the calendar quarter
ending March 31, 2004 and continuing through the date Mr. Bennett ceased to be a
"covered employee" within the meaning of Section 162(m) of the Internal Revenue
Code of 1986, as amended (Section 162(m)), together with an 8% investment return
thereon, compounded quarterly, through such date. The amount in this account
would have been payable within 30 days of such date. Under the January 2004
Agreement, the Company will cease to credit the $12,500 to Mr. Bennett's account
following March 31, 2006. The January 2004 Agreement also provides that the
amount in this account, including the investment return accrued through March
31, 2008, will be payable to Mr. Bennett within ten business days following
March 31, 2008.

         Also, on December 28, 2005, the Company and Mr. Bennett amended and
restated Mr. Bennett's Deferred Compensation Agreement, originally dated October
15, 2004 (as so amended and restated, the October 2004 Agreement). Under the
original agreement, the Company credited $1,000,000 to an account in the name of
Mr. Bennett as of July 1, 2004, and agreed to credit an 8% investment return
thereon, compounded quarterly, through the date Mr. Bennett ceased to be a
"covered employee" within the meaning of Section 162(m). The amount in this
account would have been payable within 30 days of such date. The October 2004
Agreement also provides that the amount in this account, including the
investment return accrued through March 31, 2008, will be payable to Mr. Bennett
within ten business days following March 31, 2008.

         Mr. Bennett and the Company are also party to a separate Deferred
Compensation Agreement, dated as of July 1, 2005 (the July 2005 Agreement),
pursuant to which the Company credited $1,000,000 to an account in the name of
Mr. Bennett as of July 1, 2005, and agreed to credit an 8% investment return
thereon, compounded quarterly, through March 31, 2008. The amount in this
account will be payable to Mr. Bennett within ten business days following March
31, 2008.

         The foregoing description of the January 2004 Agreement, the October
2004 Agreement and the July 2005 Agreement is not complete and is qualified in
its entirety by reference to the full text of the January 2004 Agreement, the
October 2004 Agreement and the July 2005 Agreement, which are filed as Exhibit
99.2, 99.3 and 99.4, respectively, hereto.
