Dear Russ:

This letter agreement will confirm certain terms and conditions relating to the
cash sign-on bonus provided under the employment offer letter between you and
Orbitz Worldwide, Inc. (the "Company") dated December 30, 2010 (the "Employment
Letter Agreement"). Specifically, you are to receive a cash-sign-on bonus of up
to $531,000, less applicable taxes, payable within thirty (30) days of your
employment start date, subject to adjustment and full or partial repayment if
you resign or are terminated by the Company for "Cause" (as defined in the
Employment Letter Agreement) within two (2) years of your employment start date.
This cash sign-on bonus is to make you "whole" to the extent you do not receive
your 2010 bonus from Crocs Incorporated ("Crocs").

The Employment Letter Agreement provides that any 2010 bonus you receive from
Crocs will be deducted from the cash sign-on bonus paid to you by the Company.
However, we understand that you may not receive your 2010 bonus payment from
Crocs until after the date your sign-on bonus from the Company is due and
payable. Therefore, you agree to repay the Company as follows: (i) within five
(5) days from the date you receive the 2010 bonus from Crocs you shall make a
payment to the Company by check equal to: (a) the amount you received from Crocs
as your 2010 bonus, minus (b) all income and employment taxes deducted by the
Company with respect to your prior receipt of an equivalent amount from the
Company, and (ii) you authorize the Company to receive and retain a refund from
the applicable taxing authorities of all income and employment taxes paid on
your behalf with respect to your prior receipt of such amount from the Company.

Regards,
