2. The first sentence of Section 2 of the Original Agreement is hereby amended and restated to read as follows:

“The Employee’s title is Chief Executive Officer—International, as such title may be amended upon the mutual agreement of the parties.”

3. The first and second sentences of Section 3(a) (“Base Salary”) of the Original Agreement are hereby deleted and replaced with the following sentences:

“Effective January 1, 2011, Live Nation will pay the Employee an annual gross base salary of £455,000.00 (GBP), less appropriate withholdings. The Employee will be eligible for annual increases in such gross base salary in Live Nation’s sole discretion and in accordance with company policy.”
