On the other hand,

FOR MEMORY IT IS REMINDED THAT:

The employee was recruited on April, 9th 2006 and today holds the role of Health Physics Group Division President. Article 5.4 of the original contract of employment mentioned the granting of an expatriation allowance calculated on the basis of a number of days abroad, out of the home country. This allowance concerned only the countries of Western Europe and Americas (North and South). Given the fact that the employee must travel extensively throuhout the world to fulfill this role, it appeared necessary for both sides to extend this clause and to standardize it according to a middle table.

AS A CONSEQUENCE IT IS AGREED THE FOLLOWING:

ARTICLE I — MODIFICATION OF THE CLAUSE 5.4 OF THE CONTRACT OF EMPLOYMENT

The time spent outside the French territory will be the subject of an expatriation allowance calculated according to the same principle as before but on the following basis:

		All countries of the world
Yearly cumulated period		except French territory
20 to 30 days			6	%
31 to 45 days			8	%
46 to 60 days			12	%
61 to 75 days			15	%
76 to 90 days			20	%
More than 90 days			30	%

ARTICLE II — VARIOUS ARRANGEMENTS.

The other articles of the previous contract remain unchanged.
