Dear Layne:

     On behalf of the Board of Directors of Replay Networks, Inc. ("Replay"), I

Networks on the terms set forth below.

You will have sole overall responsibility for the management of all of Replay's
network service elements, including but not limited to, Replay's core service
business of media business development, editorial, programming, business
affairs, scheduling, affiliate relations and advertising sales, and you will
report directly and only to the Chief Executive Officer. During your term, you
will be present at all Board of Directors meetings. During your term, you will
be expected to devote your full working time and attention to the business of
Replay. Notwithstanding the foregoing, you may (i) serve on the board of
directors of DEN and on other boards of directors of organizations that are not
competitive with Replay, that do not materially interfere with your duties to
Replay and that are approved by Replay, (ii) serve as a consultant to UPN
through December 31, 1999, so long as such activity does not materially
interfere with your duties to Replay, or (iii) own up to 1% of the outstanding
equity securities of any corporation whose stock is listed on a national stock
exchange. You will also be expected to comply with and be bound by Replay's
operating policies, procedures and practices that are from time to time in
effect during the term of your employment.

     2.   Base Salary. Your initial base monthly salary will be $20,000, or
          -----------
a base annual salary of $240,000, payable in accordance with Replay's normal
payroll practices with such payroll deductions and withholdings as are required
by law. Your base salary will be reviewed on an annual basis by the Compensation
Committee of the Board of Directors and increased from time to time, in the
discretion of the Board of Directors, but in any event such compensation shall
not be reduced below $240,000.

                                       1

     3.  Bonus. You will be eligible to receive an annual bonus based on the
         -----

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

         On the Commencement Date, the Compensation Committee of the Board of
Directors shall grant you an option to purchase 560,000 shares of Common Stock
at an exercise price equal to $1.25 per share, which options shall be "incentive
stock options" to the maximum extent permitted under the Internal Revenue Code
of 1986, as amended. These shares will vest ratably on a monthly basis over 48
months commencing with your first day of employment. The option will be
immediately exercisable, subject to repurchase of the unvested shares by Replay
on termination of employment at your original purchase price, which repurchase
option will lapse over the 48 month vesting schedule. You will be permitted to
pay for shares with a full recourse promissory note with interest accruing at
the minimum applicable federal rate and with principal and interest deferred for
five years and payable in a balloon payment on the fifth anniversary of the
grant, subject to acceleration 30 days following termination of employment. You
should consult a tax advisor concerning your income tax consequences before
exercising any of the options. Notwithstanding any other provision of this
Section 4 to the contrary, upon "Involuntary Termination," "Termination without
Cause," or "Termination for Death or Disability," unvested shares shall vest as
provided in Section 8 below, and grant of the option to you shall be subject to
