Exhibit 10.23

November 30, 2005

Dan Sheeran
c/o RealNetworks, Inc.
2601 Elliott Avenue, Suite 1000
Seattle, WA  98121


Dear Dan:

In consideration for your excellent work relating to the Microsoft antitrust
case and your continued employment with RealNetworks, I am pleased to offer you
the bonus plan and payments described in Exhibit A (the "Bonus Payments").

You will be entitled to receive the Bonus Payments unless RealNetworks has
terminated your employment for Cause, as defined below, or you voluntarily
choose to end your employment with RealNetworks, in which case you will not be
entitled to any Bonus Payments after the date of your termination or voluntary
resignation. Once paid, a Bonus Payment will be considered final and
irrevocable. If RealNetworks materially changes your job responsibilities, moves
your primary workplace by more than 15 miles or is acquired by a third party,
any subsequent resignation by you will not be considered "voluntary" and you
will be entitled to receive all Bonus Payments on your last day of employment.
In the event of your death or permanent disability, you or your heirs will be
entitled to receive all Bonus Payments within 30 days. In addition, in the event
of any mutually agreed (a) change in your employment status to part-time for a
continuous period lasting greater than three months or (b) leave of absence for
a continuous period lasting greater than three months, the Bonus Payments may be
adjusted to reflect appropriately such change in status (for example, by
altering the payment schedule, pro-rating the payments, tolling the payment
schedule or such other mechanism as agreed by the parties). Notwithstanding the
previous sentence, there shall not be any adjustment to the Bonus Payments or
schedule as a result of any change in employment status relating to disability
(other than a permanent disability as described above), medical or family leave
or other FMLA-related leave.

As used in this agreement, "Cause" means conduct involving one or more of the
following: (i) your substantial and continuing failure after written notice to
render services to RealNetworks in accordance with the terms or requirements of
your employment for reasons other than illness or incapacity; or (ii) willful
misconduct, fraud, embezzlement, theft, misrepresentation or dishonesty
involving RealNetworks resulting in any case in material harm to RealNetworks.

Sincerely,

/s/ Rob Glaser

Rob Glaser
Chairman and Chief Executive Officer
RealNetworks, Inc.

I have read and agree to the terms of the incentive bonus agreement contained in
this letter.

Name: /s/ Dan Sheeran
