Re: SIDELETTER/EMPLOYMENT AGREEMENT

Dear Mr. Shell:

Enclosed you will find two revised copies of the Employment Agreement between
you and Liberty/Fox U.S. Sports LLC for your review and signature. Please sign
each Agreement and return all copies for final execution. A fully executed
Agreement will be returned to you for your files.

In addition to the terms of the Agreement set forth in the attached, there are a
number of items not specifically addressed which will be described herein and
which will apply to your employment.

1.  You shall participate in the Company's bonus program in the same manner as
Senior Vice Presidents. Due to the limited history of the Company, the Company
agrees that any bonus payment will be calculated comparable to the current Fox
program. Payment of any bonus is entirely at the discretion of the Company.

2.  If the Company offers a stock appreciation plan or other equity appreciation
plans, you shall be entitled to the benefit in the same manner as other Senior
Vice Presidents.

3.  The Company agrees to pay you $3,000, less normal deductions, upon the
execution of your Agreement.  You will be eligible to participate in all such
plans to the same extent as comparable executives and any other plans in which
Senior Vice Presidents participate. Should the underlying policies which address
these areas change in a manner which affects other Senior Vice Presidents of the
Company, you will be similarly affected.

Sincerely,

LIBERTY/FOX U.S. SPORTS LLC

8.   You will not during the term of your employment and for a period of two
years thereafter, directly or indirectly, induce or attempt to induce any

     deemed by the Company to be proprietary in nature, unless disclosure is
     permitted by the Company or required by law.

     (c)  The Company shall have the right to use your name, approved biography
     and approved likeness in connection with its business, including in
     advertising its products and services, and may grant this right to others,

be governed by the rules applicable to comparable executives. All accrued
benefits will transfer to the new position except pension.

11.  The services to be furnished by you hereunder and the rights and privileges
granted to the Company by you are of a special, unique, unusual, extraordinary,
and intellectual character which gives them a peculiar value, the loss of which
cannot be reasonably or adequately compensated in damages in any action at law,
and a breach by you of any of the provisions contained herein will cause the
Company irreparable injury and damage. You expressly agree that the Company
shall be entitled to seek injunctive and other equitable relief to prevent a
breach of this Agreement by you. Resort to such equitable relief, however, shall
not be construed as a waiver of any preceding or succeeding breach of the same
or any other term or provision. The various rights and remedies of the Company
hereunder shall be construed to be cumulative and no one of them shall be
exclusive of any other or of any right or remedy allowed by law.

12.  In consideration of the making of this Agreement, as well as of the other
consideration stated herein, you expressly agree that any contract, agreement or
understanding between you and the Company with respect to severance or
termination pay, notice of severance or termination, or pay in lieu of notice of
severance or termination previously extended to you whether by way of contract,
letter, or Company termination policy, is hereby rescinded. You further agree
that if you continue in the employ of the Company after the end of this
Agreement, your employment shall be at-will and shall otherwise be in accordance
with the provisions of such then existing Company policies as may then be in
effect applicable to comparable executives of the Company.
